In response to the challenges of the COVID-19 pandemic, iPLEDGE announced that they would accept results from home pregnancy tests and explicitly permit telemedicine.¹ Given the financial and logistical burdens associated with iPLEDGE, these changes have the potential to increase access.² However, it is unclear whether these modifications will be allowed to continue. We sought to evaluate clinician perspectives on the role of telemedicine and home pregnancy testing for iPLEDGE.

After piloting among several clinicians, a 13-question survey was distributed using the Qualtrics platform to members of the American Acne & Rosacea Society between April 14, 2021, and June 14, 2021. This survey consisted of items addressing provider practices and perspectives on telemedicine and home pregnancy testing for patients taking isotretinoin (eTable). Respondents were asked whether they think telemedicine and home pregnancy testing have improved access to care and whether they would like to continue these practices going forward. In addition, participants were asked about their concerns with home pregnancy testing and how comfortable they feel with home pregnancy testing for various contraceptive strategies (abstinence, condoms, combined oral contraceptives, and long-acting reversible contraception). This study was deemed exempt (category 2) by the University of Pennsylvania (Philadelphia, Pennsylvania) institutional review board (Protocol #844549).

Among 70 clinicians who completed the survey (response rate, 6.4%), 33 (47.1%) practiced in an academic setting. At the peak of the COVID-19 pandemic, clinicians reported using telemedicine for a median of 90% (IQR=50%–100%) of their patients on isotretinoin, and 57 respondents (81.4%) reported having patients use a home pregnancy test for iPLEDGE (Table 1). More than 75% (55/70) agreed that they would like to continue to use telemedicine for patients on isotretinoin, and more than 75% (54/70) agreed that they would like to continue using home pregnancy testing for patients outside the setting of the COVID-19 pandemic. More than 75% (54/70) agreed that telemedicine has increased access for their patients, and more than 70% (52/70) agreed that home pregnancy testing has increased access (Table 2). Clinicians agreed that they would be comfortable using home pregnancy testing for patients choosing long-acting reversible contraception (63/70 [90.0%]), combined oral contraceptives (61/69 [88.4%]), condoms (47/70 [67.1%]), or abstinence (48/70 [68.6%])(Table 3).

The most common concerns about home pregnancy testing were patient deception (39/70 [55.7%]), logistical challenges with reviewing results (19/70 [27.1%]), accuracy of the tests (19/70 [27.1%]), and patient ability to interpret tests appropriately (18/70 [25.7%]). To document testing results, 50 respondents (73.5%) would require a picture of results, 4 (5.9%) would accept a written report from the patient, and 14 (20.6%) would accept a verbal report from the patient (Table 2).

In this survey, clinicians expressed interest in continuing to use telemedicine and home pregnancy testing to care for patients with acne treated with isotretinoin. More than 75% agreed that these changes have increased access, which is notable, as several studies have identified that female and minority patients may face iPLEDGE-associated access barriers.^3,4 Continuing to allow home pregnancy testing and explicitly permitting telemedicine can enable clinicians to provide patient-centered care.²

Although clinicians felt comfortable with a variety of contraceptive strategies, particularly those with high reported effectiveness,⁵ there were concerns about deception and interpretation of test results. Future studies are needed to identify optimal workflows for home pregnancy testing and whether patients should be required to provide a photograph of the results.

This survey study is limited by the possibility of sampling and response bias due to the low response rate. Although the use of national listservs was employed to maximize the generalizability of the results, given the response rate, future studies are needed to evaluate whether these findings generalize to other settings. In addition, given iPLEDGE-associated access barriers, further research is needed to examine how changes such as telemedicine and home pregnancy testing influence both access to isotretinoin and pregnancy prevention.

The current understanding of the pathogenesis of acne includes altered keratinization, follicular obstruction, overproduction of sebum, and microbial colonization ( Cutibacterium acnes ) of the pilosebaceous unit resulting in perifollicular inflammation. ¹ A deeper dive into the hormonal and molecular drivers of acne have implicated insulin, insulinlike growth factor 1 (IGF-1), corticotropin-releasing hormone, the phosphoinositide 3 -kinase/Akt pathway, mitogen-activated protein kinase pathway, and the nuclear factor κ B pathway. ^2-4 A Western diet comprised of high glycemic index foods, carbohydrates, and dairy enhances the production of insulin and IGF-1. A downstream effect of excess insulin and IGF-1 is overactivity of the mammalian target of rapamycin complex 1 (mTORC1), a major promoter of cellular growth and proliferation that primarily is regulated through nutrient availability. ⁵ This article will review our understanding of the impact of the Western diet on acne pathogenesis and highlight the existing evidence behind the contributions of the mTORC1 pathway in this process. Although quality randomized controlled trials analyzing these effects are limited, dermatologists should understand the existing evidence supporting the potential impacts of diet on acne.

The Western Diet

Glycemic Index—To assess the impact of a high glycemic index diet on acne, Kwon et al⁶ evaluated 32 patients with mild to moderate acne and placed them on a low or high glycemic index diet for 10 weeks. The low glycemic index diet group was found to have a 70% reduction in the mean number of inflammatory acne lesions from baseline (P<.05), while the high glycemic index diet group had no significant reduction. Noninflammatory lesion counts remained statistically unchanged.⁶ Smith et al⁷ studied 43 male patients with acne on either a low glycemic index diet or a self-directed high glycemic diet that was carbohydrate dense. The low glycemic index group showed greater improvement in lesion count as well as improved insulin sensitivity at 12 weeks. Specifically, the mean lesion count (SEM) decreased by 23.5 (3.9) in the low glycemic index group and by only 12.0 (3.5) in the control group (P=.03).⁷ Observational studies also have supported this hypothesis. After adjustment, an analysis of 24,452 participants in the NutriNet-Santé cohort found significant associations between current acne and the consumption of sugary beverages (adjusted OR, 1.18; 95% CI, 1.01-1.38) and the consumption of fatty and sugary products (adjusted OR, 1.54; 95% CI, 1.09-2.16).⁸ A Cochrane review that included only 2 studies (Kwon et al⁶ and Smith et al⁷) did not find evidence to suggest a low glycemic index diet for noninflammatory lesion count reduction but did note possible benefit for a reduction in inflammatory and total lesion counts; however, Kwon et al⁶ had incomplete data.⁹

Dairy—A large retrospective study including 47,355 nurses noted the frequency of milk intake was significantly associated with increased prevalence of acne in adolescence (prevalence ratio, 1.22; 95% CI, 1.03-1.44; P=.002).¹⁰ A 2019 meta-analysis further suggested a significant relationship between acne and milk in highest vs lowest intake groups (OR, 1.48; 95% CI, 1.31-1.66) with no significant heterogeneity between the studies (I²=23.6%, P=.24 for heterogeneity), as well as a positive relationship between the highest vs lowest intake of low-fat milk (OR, 1.25; 95% CI, 1.10-1.43) and skim milk (OR, 1.82; 95% CI, 1.34-2.47). In this meta-analysis, yogurt and cheese consumption were not significantly associated with acne (OR, 0.90; 95% CI, 0.73-1.11).¹¹ One non–evidence-based explanation for this may be that fermented dairy products have different biological actions. Pasteurized milk allows microRNAs that directly activate mTORC1 to persist, whereas the bacteria present in the fermentation process may augment this.¹² A separate meta-analysis from 2018 did find that yogurt consumption was positively associated with acne (OR, 1.36; 95% CI, 1.05-1.77; P=.022), highlighting the need for larger, more rigorous studies on this topic.¹³

Insulin and IGF-1—As reviewed above, acne has been considered a disease of Western society, with the Western diet at the center of this association.¹⁴ A typical Western diet consists of high glycemic index foods, carbohydrates, and dairy, all of which enhance the production of insulin and IGF-1. Insulin levels increase secondary to high blood glucose and to a lesser degree by protein intake.¹⁵ Insulinlike growth factor 1 production is most influenced by age and peaks during puberty; however, high protein diets also increase liver IGF-1 production and release.¹⁶ When present in excess, insulin can function as a growth factor. Insulin exerts its anabolic effects through the IGF-1 pathway; however, insulin and IGF-1 are produced in response to different signals.¹⁷ Endocrine production of IGF-1 represents 70% of blood levels, peaks at puberty, and rapidly declines in the third decade of life.¹⁸ Insulin is produced by the pancreas, and levels correspond to lifestyle and genetically induced insulin resistance.¹⁹

Adolescents have elevated levels of IGF-1 as a major driver of puberty-associated growth.²⁰ Despite the natural decrease in IGF-1 following puberty, acne persists in many patients and can even develop for the first time in adulthood in a subset of patients. A study of 40 acne patients and 20 controls found that patients with acne who consumed a high glycemic–load diet was significantly higher than the number of controls consuming a similar diet (P=.008). Additionally, significantly higher levels of mean (SD) serum IGF-1 on quantitative sandwich enzyme-linked immunosorbent assay in acne patients vs controls (543.2 [174.7] ng/mL vs 316.9 [95.7] ng/mL; P<.001) was identified, and these levels correlated significantly with high glycemic–load diet consumption.²¹ In another study, Kartal et al²² found that basal and fasting insulin levels and homeostasis model assessment scores evaluating for insulin resistance were significantly higher in 36 women compared with 24 age/sex-matched controls (P<.05). This finding remained significant even after excluding women with hyperandrogenemia (P<.05).²²

Highlighting the importance of IGF-1 in the pathogenesis of acne, patients with genetic disorders characterized by IGF-1 deficiency, such as Laron syndrome, do not develop acne despite having a functional androgen receptor. Treatment with IGF-1 in these patients induces acne, further supporting the role of IGF-1 in the pathogenesis of this condition.²³

The mTORC1 Pathway

Comprised of mTOR in addition to other proteins, mTORC1 is a nutrient-sensitive regulator of cellular growth, proliferation, lipid synthesis, and protein translation.⁵ Increased activity of mTORC1 has been described in diabetes, neurodegenerative disease, and cancer,^14,24 while decreased activity may promote longevity.²⁵ Regulation of mTORC1 occurs through several mechanisms. Growth factors such as insulin and IGF-1 promote mTORC1 activation through the PI3K/Akt pathway. Several amino acids—specifically branched chain amino acids such as alanine, arginine, asparagine, glutamine, histidine, leucine, methionine, serine, threonine, and valine—also can activate mTORC1 independently.²⁶ Excess glucose leads to decreased adenosine monophosphate–activated protein kinase and increased activity of mTORC1, which occurs separately from insulin or IGF-1.²⁷ Starvation blocks mTORC1 via increased adenosine monophosphate–activated protein kinase and starvation-induced hypoxia.^26,28 To activate mTORC1, both the IGF-1 or insulin signal and amino acid excess must be present.²⁹ Although not studied in acne, altering the dietary protein content in obese mice has been shown to perturb the mTORC1 pathway, leading to pathologic changes in the mTORC1-autophagy signaling axis, increased amino acid release into the blood, and an acute elevation in mTORC1 signaling.³⁰

Another major regulator of mTORC1 is Forkhead box protein O1 (FOXO1), which is a transcription factor that regulates mTORC1 through sestrin 3.^31,32 Sestrin 3 is a stress-induced protein that helps regulate blood glucose and promote insulin sensitivity.³³ When FOXO1 is translocated to the cell nucleus, it upregulates the expression of sestrin 3, resulting in mTORC1 inhibition.^31,32 Insulin, IGF-1, and nutrient excess lead to FOXO1 translocation to the cell cytoplasm where it can no longer mitigate mTORC1 activity, while the fasted state leads to translocation to the nucleus.³⁴ A single study evaluated the association between FOXO1, mTORC1, a high glycemic–load diet, and acne development. Immunohistochemical detection of mTORC1 assessed by digital image analysis revealed significantly greater expression in inflamed pilosebaceous units found in acne patients (P<.001). Immunohistochemical cytoplasmic expression of FOXO1 and mTOR (used as a proxy for mTORC1) was significantly higher in patients on a high glycemic–load diet (P=.021 and P=.009, respectively) as well as in patients with more severe forms of acne (P=.005 and P=.015, respectively) and elevated IGF-1 levels (P=.004 and P=.003, respectively).²¹

mTORC1 contributes to the proliferation of keratinocytes and excess sebum production, both independently and through androgen-mediated processes.^35-40 Insulinlike growth factor 1 binding the IGF-1 receptor leads to proliferation of keratinocytes lining the sebaceous gland and hair follicle in vivo.³⁵ In mice with epidermis-specific deletion of mTOR, keratinocyte proliferation was decreased and hair follicles were diminished both in number and development. Genetic loss of mTOR in the epidermis led to attenuated signaling pathways of mTORC1 and mTORC2.³⁶

Androgen function is augmented by mTORC1, FOXO1, and IGF-1 through several mechanisms, which may partially explain the hormonal relationship to acne. Androgens increase IGF-1 within the hair follicle.³⁷ In prostate cancer cells, IGF-1 then facilitates movement of FOXO1 to the cytoplasm, preventing it from blocking mTORC1. This effective inactivation of FOXO1 thus further augments the impact of androgens by both allowing unchecked mTORC1 pathway activity and increasing translocation of the androgen receptor (AR) to the nucleus where it exerts its effects.³⁸ Interestingly, genetic polymorphisms of the AR have been shown to cause variable affinity of FOXO1 for the AR; specifically, shorter CAG (cytosine, adenine, guanine) repeat length may lead to decreased FOXO1 binding and is associated with an increased risk for acne.^41-43 In addition to its effects on the hair follicle, IGF-1 stimulates production of testosterone and dehydroepiandrosterone as well as activates 5α-reductase, leading to higher dihydrotestosterone levels, which activate the AR with higher affinity than testosterone.⁴⁴ In some tissues, androgens help regulate the mTORC1 pathway through positive feedback loops.^45,46 At this time, we do not know if this occurs in the pathogenesis of acne.

Isotretinoin is the treatment of choice for refractory acne. It has been hypothesized that isotretinoin induces sebocyte apoptosis via the upregulation of FOXO transcription factors and p53.⁴⁷ Elevated levels of nuclear FOXO1 have been found in the sebaceous glands of patients following initiation of treatment with isotretinoin and are hypothesized to play a major role in the drug’s effectiveness. Specifically, biopsies from 14 acne patients before and after 6 weeks of isotretinoin therapy were analyzed with immunohistochemical staining and found to have a significantly improved nuclear to cytoplasmic ratio of nonphosphorylated FOXO1 (P<.001).⁴⁷

Practical Recommendations

Given the available evidence, it is important for dermatologists to address dietary recommendations in acne patients. Although large randomized controlled trials on diet and acne severity are challenging to conduct in this population, the existing literature suggests that patients should avoid high glycemic index simple sugars and processed grains, and patients should focus on eating more complex carbohydrates in the form of legumes, vegetables, fruits, and tubers.^6-8 With regard to dairy, milk (especially skim) has been associated with increased risks for acne.^11,13 Fermented dairy products may have less impact on acne severity and include cheese, yogurt (unsweetened to keep glycemic index low), and sour cream.¹² Additionally, dermatologists can consider evaluating acne patients for insulin resistance with a hemoglobin A_1c or oral glucose tolerance test; however, these are not perfect markers of insulin sensitivity. This should be considered in patients with clinical features suggesting metabolic derangement such as acanthosis nigricans; elevated nonfasting triglycerides; or symptoms of polycystic ovarian syndrome, which include irregular menstruation, hirsutism, and early-onset androgenetic alopecia (also an independent sign of insulin resistance in men).^48-51

The current understanding of the pathogenesis of acne includes altered keratinization, follicular obstruction, overproduction of sebum, and microbial colonization ( Cutibacterium acnes ) of the pilosebaceous unit resulting in perifollicular inflammation. ¹ A deeper dive into the hormonal and molecular drivers of acne have implicated insulin, insulinlike growth factor 1 (IGF-1), corticotropin-releasing hormone, the phosphoinositide 3 -kinase/Akt pathway, mitogen-activated protein kinase pathway, and the nuclear factor κ B pathway. ^2-4 A Western diet comprised of high glycemic index foods, carbohydrates, and dairy enhances the production of insulin and IGF-1.

Another major regulator of mTORC1 is Forkhead box protein O1 (FOXO1), which is a transcription factor that regulates mTORC1 through sestrin 3.^31,32 Sestrin 3 is a stress-induced protein that helps regulate blood glucose and promote insulin sensitivity.³³ When FOXO1 is translocated to the cell nucleus, it upregulates the expression of sestrin 3, resulting in mTORC1 inhibition.^31,32 Insulin, IGF-1, and nutrient excess lead to FOXO1 translocation to the cell cytoplasm where it can no longer mitigate mTORC1 activity, while the fasted state leads to translocation to the nucleus.³⁴ A single study evaluated the association between FOXO1, mTORC1, a high glycemic–load diet, and acne development. Immunohistochemical detection of mTORC1 assessed by digital image analysis revealed significantly greater expression in inflamed pilosebaceous units found in acne patients (P<.001). Immunohistochemical cytoplasmic expression of FOXO1 and mTOR (used as a proxy for mTORC1) was significantly higher in patients on a high glycemic–load diet (P=.021 and P=.009, respectively) as well as in patients with more severe forms of acne (P=.005 and P=.015, respectively) and elevated IGF-1 levels (P=.004 and P=.003, respectively).²¹

mTORC1 contributes to the proliferation of keratinocytes and excess sebum production, both independently and through androgen-mediated processes.^35-40 Insulinlike growth factor 1 binding the IGF-1 receptor leads to proliferation of keratinocytes lining the sebaceous gland and hair follicle in vivo.³⁵ In mice with epidermis-specific deletion of mTOR, keratinocyte proliferation was decreased and hair follicles were diminished both in number and development. Genetic loss of mTOR in the epidermis led to attenuated signaling pathways of mTORC1 and mTORC2.³⁶

Androgen function is augmented by mTORC1, FOXO1, and IGF-1 through several mechanisms, which may partially explain the hormonal relationship to acne. Androgens increase IGF-1 within the hair follicle.³⁷ In prostate cancer cells, IGF-1 then facilitates movement of FOXO1 to the cytoplasm, preventing it from blocking mTORC1. This effective inactivation of FOXO1 thus further augments the impact of androgens by both allowing unchecked mTORC1 pathway activity and increasing translocation of the androgen receptor (AR) to the nucleus where it exerts its effects.³⁸ Interestingly, genetic polymorphisms of the AR have been shown to cause variable affinity of FOXO1 for the AR; specifically, shorter CAG (cytosine, adenine, guanine) repeat length may lead to decreased FOXO1 binding and is associated with an increased risk for acne.^41-43 In addition to its effects on the hair follicle, IGF-1 stimulates production of testosterone and dehydroepiandrosterone as well as activates 5α-reductase, leading to higher dihydrotestosterone levels, which activate the AR with higher affinity than testosterone.⁴⁴ In some tissues, androgens help regulate the mTORC1 pathway through positive feedback loops.^45,46 At this time, we do not know if this occurs in the pathogenesis of acne.

Isotretinoin is the treatment of choice for refractory acne. It has been hypothesized that isotretinoin induces sebocyte apoptosis via the upregulation of FOXO transcription factors and p53.⁴⁷ Elevated levels of nuclear FOXO1 have been found in the sebaceous glands of patients following initiation of treatment with isotretinoin and are hypothesized to play a major role in the drug’s effectiveness. Specifically, biopsies from 14 acne patients before and after 6 weeks of isotretinoin therapy were analyzed with immunohistochemical staining and found to have a significantly improved nuclear to cytoplasmic ratio of nonphosphorylated FOXO1 (P<.001).⁴⁷

Practical Recommendations

Given the available evidence, it is important for dermatologists to address dietary recommendations in acne patients. Although large randomized controlled trials on diet and acne severity are challenging to conduct in this population, the existing literature suggests that patients should avoid high glycemic index simple sugars and processed grains, and patients should focus on eating more complex carbohydrates in the form of legumes, vegetables, fruits, and tubers.^6-8 With regard to dairy, milk (especially skim) has been associated with increased risks for acne.^11,13 Fermented dairy products may have less impact on acne severity and include cheese, yogurt (unsweetened to keep glycemic index low), and sour cream.¹² Additionally, dermatologists can consider evaluating acne patients for insulin resistance with a hemoglobin A_1c or oral glucose tolerance test; however, these are not perfect markers of insulin sensitivity. This should be considered in patients with clinical features suggesting metabolic derangement such as acanthosis nigricans; elevated nonfasting triglycerides; or symptoms of polycystic ovarian syndrome, which include irregular menstruation, hirsutism, and early-onset androgenetic alopecia (also an independent sign of insulin resistance in men).^48-51

The current understanding of the pathogenesis of acne includes altered keratinization, follicular obstruction, overproduction of sebum, and microbial colonization ( Cutibacterium acnes ) of the pilosebaceous unit resulting in perifollicular inflammation. ¹ A deeper dive into the hormonal and molecular drivers of acne have implicated insulin, insulinlike growth factor 1 (IGF-1), corticotropin-releasing hormone, the phosphoinositide 3 -kinase/Akt pathway, mitogen-activated protein kinase pathway, and the nuclear factor κ B pathway. ^2-4 A Western diet comprised of high glycemic index foods, carbohydrates, and dairy enhances the production of insulin and IGF-1. A downstream effect of excess insulin and IGF-1 is overactivity of the mammalian target of rapamycin complex 1 (mTORC1), a major promoter of cellular growth and proliferation that primarily is regulated through nutrient availability. ⁵ This article will review our understanding of the impact of the Western diet on acne pathogenesis and highlight the existing evidence behind the contributions of the mTORC1 pathway in this process. Although quality randomized controlled trials analyzing these effects are limited, dermatologists should understand the existing evidence supporting the potential impacts of diet on acne.

The Western Diet

Glycemic Index—To assess the impact of a high glycemic index diet on acne, Kwon et al⁶ evaluated 32 patients with mild to moderate acne and placed them on a low or high glycemic index diet for 10 weeks. The low glycemic index diet group was found to have a 70% reduction in the mean number of inflammatory acne lesions from baseline (P<.05), while the high glycemic index diet group had no significant reduction. Noninflammatory lesion counts remained statistically unchanged.⁶ Smith et al⁷ studied 43 male patients with acne on either a low glycemic index diet or a self-directed high glycemic diet that was carbohydrate dense. The low glycemic index group showed greater improvement in lesion count as well as improved insulin sensitivity at 12 weeks. Specifically, the mean lesion count (SEM) decreased by 23.5 (3.9) in the low glycemic index group and by only 12.0 (3.5) in the control group (P=.03).⁷ Observational studies also have supported this hypothesis. After adjustment, an analysis of 24,452 participants in the NutriNet-Santé cohort found significant associations between current acne and the consumption of sugary beverages (adjusted OR, 1.18; 95% CI, 1.01-1.38) and the consumption of fatty and sugary products (adjusted OR, 1.54; 95% CI, 1.09-2.16).⁸ A Cochrane review that included only 2 studies (Kwon et al⁶ and Smith et al⁷) did not find evidence to suggest a low glycemic index diet for noninflammatory lesion count reduction but did note possible benefit for a reduction in inflammatory and total lesion counts; however, Kwon et al⁶ had incomplete data.⁹

Dairy—A large retrospective study including 47,355 nurses noted the frequency of milk intake was significantly associated with increased prevalence of acne in adolescence (prevalence ratio, 1.22; 95% CI, 1.03-1.44; P=.002).¹⁰ A 2019 meta-analysis further suggested a significant relationship between acne and milk in highest vs lowest intake groups (OR, 1.48; 95% CI, 1.31-1.66) with no significant heterogeneity between the studies (I²=23.6%, P=.24 for heterogeneity), as well as a positive relationship between the highest vs lowest intake of low-fat milk (OR, 1.25; 95% CI, 1.10-1.43) and skim milk (OR, 1.82; 95% CI, 1.34-2.47). In this meta-analysis, yogurt and cheese consumption were not significantly associated with acne (OR, 0.90; 95% CI, 0.73-1.11).¹¹ One non–evidence-based explanation for this may be that fermented dairy products have different biological actions. Pasteurized milk allows microRNAs that directly activate mTORC1 to persist, whereas the bacteria present in the fermentation process may augment this.¹² A separate meta-analysis from 2018 did find that yogurt consumption was positively associated with acne (OR, 1.36; 95% CI, 1.05-1.77; P=.022), highlighting the need for larger, more rigorous studies on this topic.¹³

Insulin and IGF-1—As reviewed above, acne has been considered a disease of Western society, with the Western diet at the center of this association.¹⁴ A typical Western diet consists of high glycemic index foods, carbohydrates, and dairy, all of which enhance the production of insulin and IGF-1. Insulin levels increase secondary to high blood glucose and to a lesser degree by protein intake.¹⁵ Insulinlike growth factor 1 production is most influenced by age and peaks during puberty; however, high protein diets also increase liver IGF-1 production and release.¹⁶ When present in excess, insulin can function as a growth factor. Insulin exerts its anabolic effects through the IGF-1 pathway; however, insulin and IGF-1 are produced in response to different signals.¹⁷ Endocrine production of IGF-1 represents 70% of blood levels, peaks at puberty, and rapidly declines in the third decade of life.¹⁸ Insulin is produced by the pancreas, and levels correspond to lifestyle and genetically induced insulin resistance.¹⁹

Adolescents have elevated levels of IGF-1 as a major driver of puberty-associated growth.²⁰ Despite the natural decrease in IGF-1 following puberty, acne persists in many patients and can even develop for the first time in adulthood in a subset of patients. A study of 40 acne patients and 20 controls found that patients with acne who consumed a high glycemic–load diet was significantly higher than the number of controls consuming a similar diet (P=.008). Additionally, significantly higher levels of mean (SD) serum IGF-1 on quantitative sandwich enzyme-linked immunosorbent assay in acne patients vs controls (543.2 [174.7] ng/mL vs 316.9 [95.7] ng/mL; P<.001) was identified, and these levels correlated significantly with high glycemic–load diet consumption.²¹ In another study, Kartal et al²² found that basal and fasting insulin levels and homeostasis model assessment scores evaluating for insulin resistance were significantly higher in 36 women compared with 24 age/sex-matched controls (P<.05). This finding remained significant even after excluding women with hyperandrogenemia (P<.05).²²

Highlighting the importance of IGF-1 in the pathogenesis of acne, patients with genetic disorders characterized by IGF-1 deficiency, such as Laron syndrome, do not develop acne despite having a functional androgen receptor. Treatment with IGF-1 in these patients induces acne, further supporting the role of IGF-1 in the pathogenesis of this condition.²³

The mTORC1 Pathway

Comprised of mTOR in addition to other proteins, mTORC1 is a nutrient-sensitive regulator of cellular growth, proliferation, lipid synthesis, and protein translation.⁵ Increased activity of mTORC1 has been described in diabetes, neurodegenerative disease, and cancer,^14,24 while decreased activity may promote longevity.²⁵ Regulation of mTORC1 occurs through several mechanisms. Growth factors such as insulin and IGF-1 promote mTORC1 activation through the PI3K/Akt pathway. Several amino acids—specifically branched chain amino acids such as alanine, arginine, asparagine, glutamine, histidine, leucine, methionine, serine, threonine, and valine—also can activate mTORC1 independently.²⁶ Excess glucose leads to decreased adenosine monophosphate–activated protein kinase and increased activity of mTORC1, which occurs separately from insulin or IGF-1.²⁷ Starvation blocks mTORC1 via increased adenosine monophosphate–activated protein kinase and starvation-induced hypoxia.^26,28 To activate mTORC1, both the IGF-1 or insulin signal and amino acid excess must be present.²⁹ Although not studied in acne, altering the dietary protein content in obese mice has been shown to perturb the mTORC1 pathway, leading to pathologic changes in the mTORC1-autophagy signaling axis, increased amino acid release into the blood, and an acute elevation in mTORC1 signaling.³⁰

After most dermatology residents graduate from their programs, they go out into practice and will often carry with them what they learned from their teachers, especially clinicians. Everyone else in their dermatology residency programs approaches disease management and the use of different therapies in the same way, right?

It does not take very long before these same dermatology residents realize that things are different in real-world clinical practice in many ways. Most clinicians develop a range of fairly predictable patterns in how they approach and treat common skin disorders such as acne, rosacea, psoriasis, atopic dermatitis/eczema, and seborrheic dermatitis. These patterns often include what testing is performed at baseline and at follow-up.

Recently, I have been giving thought to how clinicians—myself included—change their approaches to management of specific skin diseases over time, especially as new information and therapies emerge. Are we fast adopters, or are we slow adopters? How much evidence do we need to see before we consider adjusting our approach? Is the needle moving too fast or not fast enough?

I would like to use an example that relates to acne treatment, especially as this is one of the most common skin disorders encountered in outpatient dermatologic practice. Despite lack of US Food and Drug Administration (FDA) approval for use in acne, oral spironolactone commonly is used in females, especially adults, with acne vulgaris and has a long history as an acceptable approach in dermatology.¹ Because spironolactone is a potassium-sparing diuretic, one question that commonly arises is: Do we monitor serum potassium levels at baseline and periodically during treatment with spironolactone? There has never been a definitive consensus on which approach to take. However, there has been evidence to suggest that such monitoring is not necessary in young healthy women due to a negligible risk for clinically relevant hyperkalemia.^2,3

In fact, the suggestion that there is a very low risk for clinically significant hyperkalemia in healthy young women treated with spironolactone is accurate based on population-based studies. Nevertheless, the clinician is faced with confirming the patient is in fact healthy rather than assuming this is the case due to her “young” age. In addition, it is important to exclude potential drug-drug interactions that can increase the risk for hyperkalemia when coadministered with spironolactone and also to exclude an unknown underlying decrease in renal function.¹ At the end of the day, I support the continued research that is being done to evaluate questions that can challenge the recycled dogma on how we manage patients, and I do not fault those who follow what they believe to be new cogent evidence. However, in the case of oral spironolactone use, I also could never fault a clinician for monitoring renal function and electrolytes including serum potassium levels in a female patient treated for acne, especially with a drug that has the known potential to cause hyperkalemia in certain clinical situations and is not FDA approved for the indication of acne (ie, the guidance that accompanies the level of investigation needed for such FDA approval is missing). The clinical judgment of the clinician who is responsible for the individual patient trumps the results from population-based studies completed thus far. Ultimately, it is the responsibility of that clinician to assure the safety of their patient in a manner that they are comfortable with.

It takes time to make changes in our approaches to patient management, and in the majority of cases, that is rightfully so. There are several potential limitations to how certain data are collected, and a reasonable verification of results over time is what tends to change behavior patterns. Ultimately, the common goal is to do what is in the best interest of our patients. No one can argue successfully against that.

Isotretinoin is the most effective treatment of recalcitrant acne, but because of its teratogenicity and potential association with psychiatric adverse effects, it has been heavily regulated by the US Food and Drug Administration (FDA) through the iPLEDGE program since 2006.^1,2 To manage the risk of teratogenicity associated with isotretinoin, various pregnancy prevention programs have been developed, but none of these programs have demonstrated a zero fetal exposure rate. The FDA reported 122 isotretinoin-exposed pregnancies during the first year iPLEDGE was implemented, which was a slight increase from the 120 pregnancies reported the year after the implementation of the System to Manage Accutane-Related Teratogenicity program, iPLEDGE’s predecessor.³ The iPLEDGE program requires registration of all wholesalers distributing isotretinoin, all health care providers prescribing isotretinoin, all pharmacies dispensing isotretinoin, and all female and male patients prescribed isotretinoin to create a verifiable link that only enables patients who have met all criteria to pick up their prescriptions. For patients of reproductive potential, there are additional qualification criteria and monthly requirements; before receiving their prescription every month, patients of reproductive potential must undergo a urine or serum pregnancy test with negative results, and patients must be counseled by prescribers regarding the risks of the drug and verify they are using 2 methods of contraception (or practicing abstinence) each month before completing online questions that test their understanding of the drug’s side effects and their chosen methods of contraception.⁴ These requirements place burdens on both patients and prescribers. Studies have shown that in the 2 years after the implementation of iPLEDGE, there was a 29% decrease in isotretinoin prescriptions.^1-3

We conducted a survey study to see if clinicians chose not to prescribe isotretinoin to appropriate candidates specifically because of the administrative burden of iPLEDGE. Secondarily, we investigated the medications these clinicians would prescribe instead of isotretinoin.

Methods

In March 2020, we administered an anonymous online survey consisting of 12 multiple-choice questions to verified board-certified dermatologists in the United States using a social media group. The University of Rochester’s (Rochester, New York) institutional review board determined that our protocol met criteria for exemption (IRB STUDY00004693).

Statistical Analysis—Primary analyses used Pearson χ² tests to identify significant differences among respondent groups, practice settings, age of respondents, and time spent registering patients for iPLEDGE.

Results

Survey results from 510 respondents are summarized in the Table.

Burden of iPLEDGE—Of the respondents, 336 (65.9%) were frequent prescribers of isotretinoin, 166 (32.5%) were infrequent prescribers, and 8 (1.6%) were never prescribers. Significantly more isotretinoin prescribers estimated that their offices spend 16 to 30 minutes registering a new isotretinoin patient with the iPLEDGE program (289 [57.6%]) compared with 0 to 15 minutes (140 [27.9%]), 31 to 45 minutes (57 [11.3%]), and morethan 45 minutes (16 [3.2%])(χ²₃=22.09, P<.0001). Furthermore, 150 dermatologists reported sometimes not prescribing, and 2 reported never prescribing isotretinoin because of the burden of iPLEDGE.

Systemic Agents Prescribed Instead of Isotretinoin—Of the respondents, 73.0% (n=111) prescribed spironolactone to female patients and 88.8% (n=135) prescribed oral antibiotics to male patients instead of isotretinoin. Spironolactone typically is not prescribed to male patients with acne because of its feminizing side effects, such as gynecomastia.⁵ According to the American Academy of Dermatology guidelines on acne, systemic antibiotic usage should be limited to the shortest possible duration (ie, less than 3–4 months) because of potential bacterial resistance and reported associations with inflammatory bowel disease, Clostridium difficile infection, and candidiasis.^6,7

Prescriber Demographics—The frequency of not prescribing isotretinoin did not vary by practice setting (χ ²₄=6.44, P=.1689) but did vary by age of the dermatologist (χ²₃=15.57, P=.0014). Dermatologists younger than 46 years were more likely (Figure) to report not prescribing isotretinoin because of the administrative burden of iPLEDGE. We speculate that this is because younger dermatologists are less established in their practices and therefore may have less support to complete registration without interruption of clinic workflow.

Comment

The results of our survey suggest that the administrative burden of iPLEDGE may be compelling prescribers to refrain from prescribing isotretinoin therapy to appropriate candidates when it would otherwise be the drug of choice.

Recent Changes to iPLEDGE—The FDA recently approved a modification to the iPLEDGE Risk Evaluation and Mitigation Strategy (REMS) program based on the advocacy efforts from the American Academy of Dermatology. Starting December 13, 2021, the 3 patient risk categories were consolidated into 2 gender-neutral categories: patients who can get pregnant and patients who cannot get pregnant.⁸ The iPLEDGE website was transitioned to a new system, and all iPLEDGE REMS users had to update their iPLEDGE accounts. After the implementation of the modified program, user access issues arose, leading to delayed treatment when patients, providers, and pharmacists were all locked out of the online system; users also experienced long hold times with the call center.⁸ This change highlights the ongoing critical need for a streamlined program that increases patient access to isotretinoin while maintaining safety.

Study Limitations—The main limitation of this study was the inability to calculate a true response rate to our survey. We distributed the survey via social media to maintain anonymity of the respondents. We could not track how many saw the link to compare with the number of respondents. Therefore, the only way we could calculate a response rate was with the total number of members in the group, which fluctuated around 4000 at the time we administered the survey. We calculated that we would need at least 351 responses to have a 5% margin of error at 95% confidence for our results to be generalizable and significant. We ultimately received 510 responses, which gave us a 4.05% margin of error at 95% confidence and an estimated 12.7% response rate. Since some members of the group are not active and did not see the survey link, our true response rate was likely higher. Therefore, we concluded that the survey was successful, and our significant responses were representative of US dermatologists.

Suggestions to Improve iPLEDGE Process—Our survey study should facilitate further discussions on the importance of simplifying iPLEDGE. One suggestion for improving iPLEDGE is to remove the initial registration month so care is not delayed. Currently, a patient who can get pregnant must be on 2 forms of contraception for 30 days after they register as a patient before they are eligible to fill their prescription.⁴ This process is unnecessarily long and arduous and could be eliminated as long as the patient has already been on an effective form of contraception and has a negative pregnancy test on the day of registration. The need to repeat contraception comprehension questions monthly is redundant and also could be removed. Another suggestion is to remove the category of patients who cannot become pregnant from the system entirely. Isotretinoin does not appear to be associated with adverse psychiatric effects as shown through the systematic review and meta-analysis of numerous studies.⁹ If anything, the treatment of acne with isotretinoin appears to mitigate depressive symptoms. The iPLEDGE program does not manage this largely debunked idea. Because the program’s sole goal is to manage the risk of isotretinoin’s teratogenicity, the category of those who cannot become pregnant should not be included.

Conclusion

This survey highlights the burdens of iPLEDGE for dermatologists and the need for a more streamlined risk management program. The burden was felt equally among all practice types but especially by younger dermatologists (<46 years). This time-consuming program is deterring some dermatologists from prescribing isotretinoin and ultimately limiting patient access to an effective medication.

Acknowledgment—The authors thank all of the responding clinicians who provided insight into the impact of iPLEDGE on their isotretinoin prescribing patterns.

Isotretinoin is the most effective treatment of recalcitrant acne, but because of its teratogenicity and potential association with psychiatric adverse effects, it has been heavily regulated by the US Food and Drug Administration (FDA) through the iPLEDGE program since 2006.^1,2 To manage the risk of teratogenicity associated with isotretinoin, various pregnancy prevention programs have been developed, but none of these programs have demonstrated a zero fetal exposure rate. The FDA reported 122 isotretinoin-exposed pregnancies during the first year iPLEDGE was implemented, which was a slight increase from the 120 pregnancies reported the year after the implementation of the System to Manage Accutane-Related Teratogenicity program, iPLEDGE’s predecessor.³ The iPLEDGE program requires registration of all wholesalers distributing isotretinoin, all health care providers prescribing isotretinoin, all pharmacies dispensing isotretinoin, and all female and male patients prescribed isotretinoin to create a verifiable link that only enables patients who have met all criteria to pick up their prescriptions. For patients of reproductive potential, there are additional qualification criteria and monthly requirements; before receiving their prescription every month, patients of reproductive potential must undergo a urine or serum pregnancy test with negative results, and patients must be counseled by prescribers regarding the risks of the drug and verify they are using 2 methods of contraception (or practicing abstinence) each month before completing online questions that test their understanding of the drug’s side effects and their chosen methods of contraception.⁴ These requirements place burdens on both patients and prescribers. Studies have shown that in the 2 years after the implementation of iPLEDGE, there was a 29% decrease in isotretinoin prescriptions.^1-3

We conducted a survey study to see if clinicians chose not to prescribe isotretinoin to appropriate candidates specifically because of the administrative burden of iPLEDGE. Secondarily, we investigated the medications these clinicians would prescribe instead of isotretinoin.

Methods

In March 2020, we administered an anonymous online survey consisting of 12 multiple-choice questions to verified board-certified dermatologists in the United States using a social media group. The University of Rochester’s (Rochester, New York) institutional review board determined that our protocol met criteria for exemption (IRB STUDY00004693).

Statistical Analysis—Primary analyses used Pearson χ² tests to identify significant differences among respondent groups, practice settings, age of respondents, and time spent registering patients for iPLEDGE.

Results

Survey results from 510 respondents are summarized in the Table.

Burden of iPLEDGE—Of the respondents, 336 (65.9%) were frequent prescribers of isotretinoin, 166 (32.5%) were infrequent prescribers, and 8 (1.6%) were never prescribers. Significantly more isotretinoin prescribers estimated that their offices spend 16 to 30 minutes registering a new isotretinoin patient with the iPLEDGE program (289 [57.6%]) compared with 0 to 15 minutes (140 [27.9%]), 31 to 45 minutes (57 [11.3%]), and morethan 45 minutes (16 [3.2%])(χ²₃=22.09, P<.0001). Furthermore, 150 dermatologists reported sometimes not prescribing, and 2 reported never prescribing isotretinoin because of the burden of iPLEDGE.

Systemic Agents Prescribed Instead of Isotretinoin—Of the respondents, 73.0% (n=111) prescribed spironolactone to female patients and 88.8% (n=135) prescribed oral antibiotics to male patients instead of isotretinoin. Spironolactone typically is not prescribed to male patients with acne because of its feminizing side effects, such as gynecomastia.⁵ According to the American Academy of Dermatology guidelines on acne, systemic antibiotic usage should be limited to the shortest possible duration (ie, less than 3–4 months) because of potential bacterial resistance and reported associations with inflammatory bowel disease, Clostridium difficile infection, and candidiasis.^6,7

Prescriber Demographics—The frequency of not prescribing isotretinoin did not vary by practice setting (χ ²₄=6.44, P=.1689) but did vary by age of the dermatologist (χ²₃=15.57, P=.0014). Dermatologists younger than 46 years were more likely (Figure) to report not prescribing isotretinoin because of the administrative burden of iPLEDGE. We speculate that this is because younger dermatologists are less established in their practices and therefore may have less support to complete registration without interruption of clinic workflow.

Comment

The results of our survey suggest that the administrative burden of iPLEDGE may be compelling prescribers to refrain from prescribing isotretinoin therapy to appropriate candidates when it would otherwise be the drug of choice.

Recent Changes to iPLEDGE—The FDA recently approved a modification to the iPLEDGE Risk Evaluation and Mitigation Strategy (REMS) program based on the advocacy efforts from the American Academy of Dermatology. Starting December 13, 2021, the 3 patient risk categories were consolidated into 2 gender-neutral categories: patients who can get pregnant and patients who cannot get pregnant.⁸ The iPLEDGE website was transitioned to a new system, and all iPLEDGE REMS users had to update their iPLEDGE accounts. After the implementation of the modified program, user access issues arose, leading to delayed treatment when patients, providers, and pharmacists were all locked out of the online system; users also experienced long hold times with the call center.⁸ This change highlights the ongoing critical need for a streamlined program that increases patient access to isotretinoin while maintaining safety.

Study Limitations—The main limitation of this study was the inability to calculate a true response rate to our survey. We distributed the survey via social media to maintain anonymity of the respondents. We could not track how many saw the link to compare with the number of respondents. Therefore, the only way we could calculate a response rate was with the total number of members in the group, which fluctuated around 4000 at the time we administered the survey.

Practice Gap

Dermatology residents can struggle with surgical closure early in their training years. Although experienced dermatologic surgeons may intuitively be able to align edges for maximal cosmesis, doing so can prove challenging in the context of learning basic surgical techniques for early residents.

Furthermore, local anesthesia can distort cutaneous anatomy and surgical landmarks, requiring the surgeon to reexamine their closure technique. Patients may require position changes or may make involuntary movements, both of which require dynamic thinking and planning on the part of the dermatologic surgeon to achieve optimal outcomes.

The Technique

We propose the use of sutures to intraoperatively guide placement of the dermal needle. This technique can be used for various closure types; here, we demonstrate its use in a standard elliptical excision.

To begin, a standard length to width ellipse ratio of 3:1 is drawn with appropriate margins around a neoplasm.¹ After excision and appropriate undermining of the ellipse, we typically use deep sutures to close the deep space. The first pass of the needle through tissue can be performed in a place of the surgeon’s preference but typically abides by the rule of halves or the zipper method (Figure 1A). To determine optimal placement of the second needle pass through tissue, we recommend applying gentle opposing traction forces to the wound apices to approximate the linear outcome of the wound edges. The surgeon can use a skin hook to guide placement of the needle to the contralateral wound edge in an unassisted method of this technique (Figure 1B). The surgeon’s assistant also can aid in applying cutaneous traction along the length of the excision if the surgeon wishes to free their hands (Figure 1C). Because the risk of needlestick injury at this step is small, it is prudent for the surgeon to advise the assistant to avoid needlestick injury by keeping their hands away from the needle path in the surgical site.

Although traction is being applied to the wound apices, the deep suture should extend across the wound with just enough pressure to leave a serosanguineous notched mark in the contralateral tissue edge (Figure 1D). After releasing traction on the wound edges, the surgeon can effortlessly visualize the target for needle placement and make a throw through the tissue accordingly.

This process can be continued until wound closure is complete (Figure 2). Top sutures or adhesive strips can be placed afterward for completing approximation of the wound edges superficially.

Practice Implications

By using this technique to align wound edges intraoperatively, the surgeon can have a functional guide for needle placement. The technique allows improvement of function and cosmesis of surgical wounds, while also accounting for topographical variations in the patient’s surgical site. Approximation of the wound edges is particularly important at the beginning of closure, as the wound edges align and approximate more with each subsequent stitch, with decreasing tension.²

In addition, when operating on a curvilinear or challenging topographical surface of the body, this technique can provide a clear template for guiding suture placement for approximating wound edges. Furthermore, local biodynamic anatomy might become distorted after excision of the tissue specimen due to release of centripetal tangential forces that were present in the pre-excised skin.¹ Local change in biodynamic forces may be difficult to plan for preoperatively using other techniques.³

Although this technique can be utilized for all suture placements in closure, it is of greatest value when placing the first few sutures and when operating on nonplanar surfaces that might become distorted after excision. To ensure the best outcome, it is important to be certain that the area has been properly cleaned prior to surgery and a sterile technique is used.

The Diagnosis: Tinea Corporis Bullosa

At the time of presentation, a potassium hydroxide (KOH) preparation, fungal culture, and punch biopsy of the right ventral wrist was performed. The KOH preparation was positive for fungal hyphae characteristic of dermatophyte infections. Histologically, the biopsy showed intraepidermal and subepidermal blisters with neutrophil- and lymphocyte-rich contents (Figure 1). Fungal hyphae and spores were present within the stratum corneum and superficial epidermis (Figure 2), and fungal cultures grew Microsporum canis. The extent of the rash (upper and lower extremities, chest, and back), positive fungal culture, and KOH preparation all supported the diagnosis of tinea corporis bullosa, which was confirmed with biopsy. Oral prednisone use was discouraged and triamcinolone ointment was discontinued given that inappropriate treatment with steroids in the setting of fungal infection suppresses an inflammatory response and alters clinical appearance, obviating the persistent underlying infection.

Tinea corporis bullosa is a rare superficial dermatophyte fungal infection that often is acquired by close personto- person contact or contact with domestic animals. The infection begins as a circular pruritic plaque, generally with raised borders, which may be erythematous or hyperpigmented. By definition, tinea corporis occurs in sites other than the face, feet, hands, or groin area. Bullae formation is thought to be secondary to a delayed hypersensitivity reaction provoked by the presence of a dermatophyte antigen.¹

Linear IgA bullous dermatosis is an immunemediated disease characterized by IgA deposition at the dermoepidermal junction. Linear IgA bullous dermatosis classically presents as widespread tense vesicles in an arciform or annular pattern. Mucosal involvement is common and typically presents with erosions, ulcerations, and scarring.² Given the absence of mucosal involvement in our patient and a positive KOH preparation, linear IgA bullous dermatosis was an unlikely diagnosis.

Benign inoculation lymphoreticulosis, more commonly known as cat scratch disease (CSD), is a Bartonella henselae infection that results from a cat scratch or bite. Cat scratch disease can present as localized cutaneous and nodal involvement (lymphadenopathy) near the site of inoculation, or it may present as disseminated disease. Cutaneous lesions generally progress through vesicular, erythematous, and papular phases. Regional lymphadenopathy proximal to the inoculation site is the hallmark of CSD.³ Given the absence of lymphadenopathy in our patient as well as the sporadic distribution of lesions, CSD was an unlikely diagnosis.

Dermatitis herpetiformis (DH) is an autoimmune disorder with cutaneous manifestations of gluten sensitivity. Dermatitis herpetiformis presents as extremely pruritic papules and vesicles arranged in groups on areas such as the elbows, dorsal aspects of the forearms, knees, scalp, back, and buttocks. Most patients with DH have celiac disease or small bowel disease related to gluten sensitivity.4 Given our patient’s acute presentation in adulthood and lack of gluten sensitivity, DH was an unlikely diagnosis.

Bullous fixed drug reaction is a cutaneous eruption that typically presents in the setting of exposure to an offending drug/agent. Drug reactions can have various cutaneous presentations, with the most common being pigmented macules that progress into plaques.⁵ Given the isolated nature of our patient’s episode and apparent lack of association with medication, bullous fixed drug reaction was an unlikely diagnosis.

Tinea corporis bullosa is a rare clinical variant of tinea corporis that has only been reported in patients with a history of contact with different animals. There are many causative organisms related to tinea corporis; Trichophyton rubrum is the most common etiology of tinea corporis, while tinea corporis due to close contact with domesticated animals often is caused by M canis.⁶ The immunoinhibitory properties of the mannans in the fungal cell wall allow the organisms to adhere to the skin prior to invasion. Cutaneous invasion into dead cornified layers of the skin is credited to the proteases, subtilisinlike proteases (subtilases), and keratinases produced by the fungus.¹ There are many different clinical presentations of tinea corporis due to the variability of causative organisms. An annular (ring-shaped) lesion with a central plaque and advancing border is the most typical presentation. Tinea corporis bullosa is characterized by the presence of bullae or vesicles in the borders of the scaly plaque. Rupture of the bullae subsequently leads to erosions and crusts over the plaque.

The diagnosis of tinea corporis bullosa often is clinical if the lesion is typical and can be confirmed using KOH preparation and fungal culture. Once the diagnosis is confirmed, topical antifungals are the standard treatment approach for localized superficial tinea corporis. Systemic antifungal treatment can be initiated if the lesion is extensive, recurrent, chronic, or unresponsive to topical treatment.¹ Given our patient’s characteristic presentation, she was managed with an over-the-counter topical antifungal (terbinafine). The patient’s lesions dramatically improved, rendering oral therapy unnecessary. At 1-month follow-up, the rash had nearly resolved.

The Diagnosis: Tinea Corporis Bullosa

At the time of presentation, a potassium hydroxide (KOH) preparation, fungal culture, and punch biopsy of the right ventral wrist was performed. The KOH preparation was positive for fungal hyphae characteristic of dermatophyte infections. Histologically, the biopsy showed intraepidermal and subepidermal blisters with neutrophil- and lymphocyte-rich contents (Figure 1). Fungal hyphae and spores were present within the stratum corneum and superficial epidermis (Figure 2), and fungal cultures grew Microsporum canis. The extent of the rash (upper and lower extremities, chest, and back), positive fungal culture, and KOH preparation all supported the diagnosis of tinea corporis bullosa, which was confirmed with biopsy. Oral prednisone use was discouraged and triamcinolone ointment was discontinued given that inappropriate treatment with steroids in the setting of fungal infection suppresses an inflammatory response and alters clinical appearance, obviating the persistent underlying infection.

Linear IgA bullous dermatosis is an immunemediated disease characterized by IgA deposition at the dermoepidermal junction. Linear IgA bullous dermatosis classically presents as widespread tense vesicles in an arciform or annular pattern. Mucosal involvement is common and typically presents with erosions, ulcerations, and scarring.² Given the absence of mucosal involvement in our patient and a positive KOH preparation, linear IgA bullous dermatosis was an unlikely diagnosis.

Benign inoculation lymphoreticulosis, more commonly known as cat scratch disease (CSD), is a Bartonella henselae infection that results from a cat scratch or bite. Cat scratch disease can present as localized cutaneous and nodal involvement (lymphadenopathy) near the site of inoculation, or it may present as disseminated disease. Cutaneous lesions generally progress through vesicular, erythematous, and papular phases. Regional lymphadenopathy proximal to the inoculation site is the hallmark of CSD.³ Given the absence of lymphadenopathy in our patient as well as the sporadic distribution of lesions, CSD was an unlikely diagnosis.

Dermatitis herpetiformis (DH) is an autoimmune disorder with cutaneous manifestations of gluten sensitivity. Dermatitis herpetiformis presents as extremely pruritic papules and vesicles arranged in groups on areas such as the elbows, dorsal aspects of the forearms, knees, scalp, back, and buttocks. Most patients with DH have celiac disease or small bowel disease related to gluten sensitivity.4 Given our patient’s acute presentation in adulthood and lack of gluten sensitivity, DH was an unlikely diagnosis.

Bullous fixed drug reaction is a cutaneous eruption that typically presents in the setting of exposure to an offending drug/agent. Drug reactions can have various cutaneous presentations, with the most common being pigmented macules that progress into plaques.⁵ Given the isolated nature of our patient’s episode and apparent lack of association with medication, bullous fixed drug reaction was an unlikely diagnosis.

Tinea corporis bullosa is a rare clinical variant of tinea corporis that has only been reported in patients with a history of contact with different animals. There are many causative organisms related to tinea corporis; Trichophyton rubrum is the most common etiology of tinea corporis, while tinea corporis due to close contact with domesticated animals often is caused by M canis.⁶ The immunoinhibitory properties of the mannans in the fungal cell wall allow the organisms to adhere to the skin prior to invasion. Cutaneous invasion into dead cornified layers of the skin is credited to the proteases, subtilisinlike proteases (subtilases), and keratinases produced by the fungus.¹ There are many different clinical presentations of tinea corporis due to the variability of causative organisms. An annular (ring-shaped) lesion with a central plaque and advancing border is the most typical presentation. Tinea corporis bullosa is characterized by the presence of bullae or vesicles in the borders of the scaly plaque. Rupture of the bullae subsequently leads to erosions and crusts over the plaque.

The diagnosis of tinea corporis bullosa often is clinical if the lesion is typical and can be confirmed using KOH preparation and fungal culture. Once the diagnosis is confirmed, topical antifungals are the standard treatment approach for localized superficial tinea corporis. Systemic antifungal treatment can be initiated if the lesion is extensive, recurrent, chronic, or unresponsive to topical treatment.¹ Given our patient’s characteristic presentation, she was managed with an over-the-counter topical antifungal (terbinafine). The patient’s lesions dramatically improved, rendering oral therapy unnecessary. At 1-month follow-up, the rash had nearly resolved.

The Diagnosis: Tinea Corporis Bullosa

At the time of presentation, a potassium hydroxide (KOH) preparation, fungal culture, and punch biopsy of the right ventral wrist was performed. The KOH preparation was positive for fungal hyphae characteristic of dermatophyte infections. Histologically, the biopsy showed intraepidermal and subepidermal blisters with neutrophil- and lymphocyte-rich contents (Figure 1). Fungal hyphae and spores were present within the stratum corneum and superficial epidermis (Figure 2), and fungal cultures grew Microsporum canis. The extent of the rash (upper and lower extremities, chest, and back), positive fungal culture, and KOH preparation all supported the diagnosis of tinea corporis bullosa, which was confirmed with biopsy. Oral prednisone use was discouraged and triamcinolone ointment was discontinued given that inappropriate treatment with steroids in the setting of fungal infection suppresses an inflammatory response and alters clinical appearance, obviating the persistent underlying infection.

Tinea corporis bullosa is a rare superficial dermatophyte fungal infection that often is acquired by close personto- person contact or contact with domestic animals. The infection begins as a circular pruritic plaque, generally with raised borders, which may be erythematous or hyperpigmented. By definition, tinea corporis occurs in sites other than the face, feet, hands, or groin area. Bullae formation is thought to be secondary to a delayed hypersensitivity reaction provoked by the presence of a dermatophyte antigen.¹

The Diagnosis: Molluscum Contagiosum

A tangential shave removal with electrocautery was performed. Histopathology demonstrated numerous eosinophilic intracytoplasmic inclusion bodies (Figure), confirming a diagnosis of molluscum contagiosum (MC).

Molluscum contagiosum is a common poxvirus infection that is transmitted through fomites, contact, or self-inoculation.1 This infection most frequently occurs in school-aged children younger than 8 years^1-3; peak incidence is 6 years of age.^2,3 The worldwide estimated prevalence in children is 5.1% to 11.5%.^1,3 In children cohabitating with others infected by MC, approximately 40% of households experienced a spread of infection; the risk of transmission is not associated with greater number of lesions.⁴ In adults, infection most commonly occurs in the setting of immunodeficiency or as a sexually transmitted infection in immunocompetent patients.³ Molluscum contagiosum infection classically presents as 1- to 3-mm, flesh- or white-colored, dome-shaped, smooth papules with central umbilication.¹ Lesions often occur in clusters or lines, indicating local spread. The trunk, extremities, and face are areas that frequently are involved.^2,3

Atypical presentations of MC infection can occur, as demonstrated by our case. Involvement of hair follicles by the infection can result in follicular induction.^1,5 Secondary infection can mimic abscess formation.¹ Inflamed MC lesions demonstrating the “beginning of the end” sign often are mistaken for primary infection, which is thought to be an inflammatory immune response to the virus.⁶ Lesions located on the eye or eyelid can present as unilateral conjunctivitis, conjunctival or corneal nodules, eyelid abscesses, or chalazions.¹ Giant MC is a nodular variant of this infection measuring larger than 1 cm in size that can present similar to epidermoid cysts, condyloma acuminatum, or verruca vulgaris.^1,7 Other reported mimicked conditions include basal cell carcinoma, trichoepithelioma, appendageal tumors, keratoacanthoma, foreign body granulomas, nevus sebaceous, or ecthyma.^1,3 Molluscum contagiosum also has been reported to present as large ulcerative growths.⁸ In immunocompromised patients, deep fungal infection is another mimicker.1 Lesions on the plantar surfaces of the feet often are misdiagnosed as plantar verruca and present with pain during ambulation.⁹

The diagnosis of MC is clinical, with additional diagnostic tools reserved for more challenging situations.¹ In cases with atypical presentations, dermoscopy may aid diagnosis through visualization of orifices and vascular patterns including crown, radial, and punctiform vessels.¹⁰ Biopsy or fine-needle aspiration also can be utilized as a diagnostic tool. Histopathology often reveals pathognomonic intracytoplasmic inclusions or Henderson-Paterson bodies.^8,10 The appearance of MC can mimic other conditions that should be included in the differential diagnosis. Pyogenic granuloma often presents as a benign red papule that may grow rapidly and become pedunculated, sometimes with bleeding and crusting, though histology reveals groups of proliferating capillaries.¹¹ More than half of amelanotic melanomas present in the papulonodular form as vascular or ulcerated nodules, and others may appear as erythematous macules. Diagnosis of amelanotic melanoma is made through histologic examination, which reveals atypical melanocytes in nests or cords, in conjunction with immunohistochemical stains such as S-100.12 Spitz nevi often appear as round, dome-shaped papules that most commonly are red, pink, or fleshcolored. They appear histologically similar to melanoma with nests of atypical melanocytes and nuclear atypia.¹³

A variety of treatment modalities can be used for MC including cantharidin, curettage, and cryotherapy.¹⁴ Imiquimod no longer is recommended due to a lack of demonstrated superiority over placebo in recent studies as well as its adverse effects.³ Topical retinoids have been recommended; however, their use frequently is limited by local irritation.^3,14 Cantharidin is the most frequently utilized treatment by pediatric dermatologists. Most health care providers report subjective satisfaction with its results and efficacy, though some side effects may occur including discomfort and temporary changes in pigmentation. Treatment for MC is not required, as the condition is self-limiting.¹⁴ Therapy often is reserved for those with extensive disease, complications from lesions, cosmetic or psychological concerns, or genital involvement given the potential for sexual transmission.³ Time to resolution without treatment varies and is more prolonged in immunocompromised patients. Mean time to resolution in immunocompetent hosts has been reported as 13.3 months, but most infections are noted to clear within 2 to 4 years.^1,4 Although resolution without treatment occurs, transmission to others and negative impact on quality of life (QOL) can occur and support the need for treatment. Greater impact on QOL was observed in females, those with more lesions, and patients with a longer duration of symptoms. Moderate impact on QOL was reported in 28% of patients (n=301), and severe effects were reported in 11%.⁴

In conclusion, MC is a common, benign, treatable cutaneous viral infection that often presents as small, flesh-colored papules in children. Its appearance can mimic a variety of other conditions. In cases with abnormal presentations, definitive diagnosis with pathology can be important to differentiate MC from more dangerous etiologies that may require further treatment.

The World Health Organization declared COVID-19 a pandemic on March 11, 2020, just 4 months before the start of a new residency cycle. Referred to as “COVID interns,” PGY-1 residents transitioning out of medical school in 2020 faced an unprecedented challenge of doctoring within a confused and ill-prepared health care system, while senior residents scrambled to adjust to their rapidly changing training programs. Each subsequent week brought more sobering news of increasing hospitalizations, intensive care unit admissions, and deaths; hospitals across the country resorted to the redeployment of residents across all specialties to buffer the growing need within their internal medicine and critical care units.¹ And while the news and social media blurred into a collage of ventilator shortages, politicization of science, and “#healthcareheroes,” one study showed53.7% of medical interns (N=108) were struggling with mild to extremely severe depression, while 63.9% reported mild to severe anxiety.²

Many shortcomings of our health care system—ill preparedness, racial disparity, health illiteracy—were highlighted during the COVID-19 pandemic, and providers’ mental health was no exception.³ Classic psychosocial risk factors, such as high demands, lack of control, lack of institutional support, and absence of reward defined the workplace, leading Theorell⁴ to call it “a randomized trial for maximal worsening of the work environment.” Stress and burnout during residency are not novel concepts. A 2002 survey including 415 medical residency programs with a response from more than 4000 residents found depressive symptoms in 35% of respondents, paired with feelings of increased cynicism and decreased humanism despite major curricular reforms and duty hour limitations.⁵ Unfortunately, the statistics in the coming years hardly budged and, in the wake of the pandemic, culminated to more than 50% to 76% of physicians worldwide reporting burnout in 2020.^6-8

As a COVID intern at Brigham and Women’s Hospital (Boston, Massachusetts), I also experienced the demanding workload and witnessed the struggle of my colleagues firsthand. Brigham and Women’s Hospital, similar to many of its peer institutions, implemented frequent mental health check-ins within its curriculum. Known as the Intern Humanistic Curriculum, these check-ins essentially were an echo chamber to unload the psychological burdens of our workdays, and we eagerly shared what made us angry, sad, hopeful, and hopeless. During one such session, I learned about moral injury, a term originating in the military defined as the psychological stress resulting from actions—or the lack of actions—that violates one’s moral or ethical code.⁹ With the onslaught of patient deaths for which most of us felt unprepared, we had all endured varying degrees of moral injury. Greenberg et al⁹ described 2 potential outcomes after moral injury: (1) the development of mental health disorders such as depression and posttraumatic stress disorder, or (2) posttraumatic growth, which is the bolstering of psychological resilience. Notably, the outcome is based on the way someone is supported before, during, and after the challenging incident.⁹

With the aim of psychological growth and developing resilience, residents should prioritize mental health throughout their training. To this end, several resources are readily available, many of which I actively use or frequently revisit, which are reviewed here.

Mindfulness Meditation App

Calm (https://www.calm.com/) is one of several popular mobile applications (apps) that delivers mindfulness mediation—the practice of attending to experiences, thoughts, and emotions without bias or judgment. With more than 100 million downloads, Calm includes meditation tutorials, breathing exercises, nature scenes and sounds, and audio programs taught by mindfulness experts for $69.99 a year or $14.99 a month. Systemic reviews have demonstrated reduced sleep disturbance, decreased ruminative thoughts and emotional reactivity, and increased awareness and acceptance in those practicing mindfulness meditation. Calm users have reported these benefits, with many able to forego the time- and cost-intensive cognitive behavioral therapy that requires highly trained therapists.^10-12

Exercise to Relieve Stress

Both aerobic and anaerobic exercises are antidepressive and anxiolytic and also lower one’s overall sensitivity to stress. Whether it is governed by neurotransmitters such as the activation of the opioid systems or the release of endogenous endorphins or time spent focusing on a different task at hand, the benefits of exercise against mental stressors have been extensively studied and established.¹³ Consider obtaining a new gym membership at the start of residency or joining an intramural team. Both have the added benefit of expanding your social circle.

Socialize With Others

Social isolation and perceived loneliness are key stressors linked to neuroendocrine disturbances that underlie depression, anxiety, and even schizophrenia.^14,15 Throughout residency there will be several social events and opportunities to gather with colleagues—inside or outside of the work environment—and residents should attend as time allows. Even virtual social interactions were found to reduce stress and help in the treatment of social anxiety disorder.¹⁴

Open up to your co-residents, friends, and family about any struggles that may be invisible on the outside. Even attendings can empathize with the struggles of residency, and the mentors in place are actively trained to prioritize resident wellness. If verbal communication is not your strength, try journaling. Writing helps to untangle and better define underlying stressors and is itself meditative.^16,17 However, ensure that your journaling is focused on positive emotional responses and aims to determine the positive benefits within any stressful event; those solely expressing negative emotions were found to have higher levels of stress and anxiety afterward than they had before.¹⁷

Seek a Mental Health Specialist

As with all other human ailments, severe mental health disorders require specialists and proper medication. Unfortunately, substantial stigma accompanying mental health continues to permeate medicine, creating considerable barriers for residents in need of care.¹⁸ A 2016 survey of more than 2000 physicians found that those with mental illnesses did not seek treatment due to limited time, fear of being reported to a medical licensing board, concern over obtaining licensure, and shame or embarrassment at the diagnosis.¹⁹ Besides urging residents to seek care, more effort should be invested in addressing the stigma and ensuring confidentiality. In 2021, the internal medicine and medicine-pediatrics residency at the University of Colorado Anschutz Medical Campus (Aurora, Colorado) developed a confidential opt-out, rather than opt-in, mental health program, and appointments were made for all 80 interns in advance. In doing so, they found increased participation and self-reported wellness at a relatively low cost and simple implementation.²⁰ For trainees without such access, online or mobile therapy platforms offering electronic mental health treatment or telepsychiatry also have been employed.^21,22 The onus ultimately is still on the individual to seek the care they need. Although only an anecdotal piece of evidence, I have found the prevalence of physicians taking selective serotonin reuptake inhibitors such as escitalopram, sertraline, or fluoxetine to be strikingly common and quite beneficial.

Final Thoughts

Residency remains rife with financial, emotional, and physical stressors; even as the dust settles on the COVID-19 pandemic, the light shed on the importance of trainee mental health must remain illuminated. For the aforementioned resources to have an impact, residents need to be empowered to openly discuss mental health issues and to seek help if necessary. Finally, in 2018, the Journal of Graduate Medical Education published a 10-year prospective cohort study that found that emotional distress during residency persists in professional practice even 10 years after residency and is associated with future burnout.²³ Trainees should consider prioritizing their mental health to not only improve their quality of life in the present but also as an investment for their future.

Even virtual social interactions were found to reduce stress and help in the treatment of social anxiety disorder.¹⁴

Open up to your co-residents, friends, and family about any struggles that may be invisible on the outside. Even attendings can empathize with the struggles of residency, and the mentors in place are actively trained to prioritize resident wellness. If verbal communication is not your strength, try journaling. Writing helps to untangle and better define underlying stressors and is itself meditative.^16,17 However, ensure that your journaling is focused on positive emotional responses and aims to determine the positive benefits within any stressful event; those solely expressing negative emotions were found to have higher levels of stress and anxiety afterward than they had before.¹⁷

Seek a Mental Health Specialist

As with all other human ailments, severe mental health disorders require specialists and proper medication. Unfortunately, substantial stigma accompanying mental health continues to permeate medicine, creating considerable barriers for residents in need of care.¹⁸ A 2016 survey of more than 2000 physicians found that those with mental illnesses did not seek treatment due to limited time, fear of being reported to a medical licensing board, concern over obtaining licensure, and shame or embarrassment at the diagnosis.¹⁹ Besides urging residents to seek care, more effort should be invested in addressing the stigma and ensuring confidentiality. In 2021, the internal medicine and medicine-pediatrics residency at the University of Colorado Anschutz Medical Campus (Aurora, Colorado) developed a confidential opt-out, rather than opt-in, mental health program, and appointments were made for all 80 interns in advance. In doing so, they found increased participation and self-reported wellness at a relatively low cost and simple implementation.²⁰ For trainees without such access, online or mobile therapy platforms offering electronic mental health treatment or telepsychiatry also have been employed.^21,22 The onus ultimately is still on the individual to seek the care they need. Although only an anecdotal piece of evidence, I have found the prevalence of physicians taking selective serotonin reuptake inhibitors such as escitalopram, sertraline, or fluoxetine to be strikingly common and quite beneficial.

Final Thoughts

Residency remains rife with financial, emotional, and physical stressors; even as the dust settles on the COVID-19 pandemic, the light shed on the importance of trainee mental health must remain illuminated. For the aforementioned resources to have an impact, residents need to be empowered to openly discuss mental health issues and to seek help if necessary. Finally, in 2018, the Journal of Graduate Medical Education published a 10-year prospective cohort study that found that emotional distress during residency persists in professional practice even 10 years after residency and is associated with future burnout.²³ Trainees should consider prioritizing their mental health to not only improve their quality of life in the present but also as an investment for their future.

The World Health Organization declared COVID-19 a pandemic on March 11, 2020, just 4 months before the start of a new residency cycle. Referred to as “COVID interns,” PGY-1 residents transitioning out of medical school in 2020 faced an unprecedented challenge of doctoring within a confused and ill-prepared health care system, while senior residents scrambled to adjust to their rapidly changing training programs. Each subsequent week brought more sobering news of increasing hospitalizations, intensive care unit admissions, and deaths; hospitals across the country resorted to the redeployment of residents across all specialties to buffer the growing need within their internal medicine and critical care units.¹ And while the news and social media blurred into a collage of ventilator shortages, politicization of science, and “#healthcareheroes,” one study showed53.7% of medical interns (N=108) were struggling with mild to extremely severe depression, while 63.9% reported mild to severe anxiety.²

Many shortcomings of our health care system—ill preparedness, racial disparity, health illiteracy—were highlighted during the COVID-19 pandemic, and providers’ mental health was no exception.³ Classic psychosocial risk factors, such as high demands, lack of control, lack of institutional support, and absence of reward defined the workplace, leading Theorell⁴ to call it “a randomized trial for maximal worsening of the work environment.” Stress and burnout during residency are not novel concepts. A 2002 survey including 415 medical residency programs with a response from more than 4000 residents found depressive symptoms in 35% of respondents, paired with feelings of increased cynicism and decreased humanism despite major curricular reforms and duty hour limitations.⁵ Unfortunately, the statistics in the coming years hardly budged and, in the wake of the pandemic, culminated to more than 50% to 76% of physicians worldwide reporting burnout in 2020.^6-8

As a COVID intern at Brigham and Women’s Hospital (Boston, Massachusetts), I also experienced the demanding workload and witnessed the struggle of my colleagues firsthand. Brigham and Women’s Hospital, similar to many of its peer institutions, implemented frequent mental health check-ins within its curriculum. Known as the Intern Humanistic Curriculum, these check-ins essentially were an echo chamber to unload the psychological burdens of our workdays, and we eagerly shared what made us angry, sad, hopeful, and hopeless. During one such session, I learned about moral injury, a term originating in the military defined as the psychological stress resulting from actions—or the lack of actions—that violates one’s moral or ethical code.⁹ With the onslaught of patient deaths for which most of us felt unprepared, we had all endured varying degrees of moral injury. Greenberg et al⁹ described 2 potential outcomes after moral injury: (1) the development of mental health disorders such as depression and posttraumatic stress disorder, or (2) posttraumatic growth, which is the bolstering of psychological resilience. Notably, the outcome is based on the way someone is supported before, during, and after the challenging incident.⁹

With the aim of psychological growth and developing resilience, residents should prioritize mental health throughout their training. To this end, several resources are readily available, many of which I actively use or frequently revisit, which are reviewed here.

Mindfulness Meditation App

Calm (https://www.calm.com/) is one of several popular mobile applications (apps) that delivers mindfulness mediation—the practice of attending to experiences, thoughts, and emotions without bias or judgment. With more than 100 million downloads, Calm includes meditation tutorials, breathing exercises, nature scenes and sounds, and audio programs taught by mindfulness experts for $69.99 a year or $14.99 a month. Systemic reviews have demonstrated reduced sleep disturbance, decreased ruminative thoughts and emotional reactivity, and increased awareness and acceptance in those practicing mindfulness meditation. Calm users have reported these benefits, with many able to forego the time- and cost-intensive cognitive behavioral therapy that requires highly trained therapists.^10-12

Exercise to Relieve Stress

Both aerobic and anaerobic exercises are antidepressive and anxiolytic and also lower one’s overall sensitivity to stress. Whether it is governed by neurotransmitters such as the activation of the opioid systems or the release of endogenous endorphins or time spent focusing on a different task at hand, the benefits of exercise against mental stressors have been extensively studied and established.¹³ Consider obtaining a new gym membership at the start of residency or joining an intramural team. Both have the added benefit of expanding your social circle.

Socialize With Others
