Dermatologists have a generally favorable attitude regarding the use of artificial intelligence (AI) in their practices, but few have actually used it yet, according to the results of a small survey.

Just 9% of the 90 respondents acknowledged that they have used AI in their practices, while 81% said they had not, and 10% weren’t sure or didn’t know. Despite that lack of familiarity, however, “many embrace the potential positive benefits, such as reducing misdiagnoses” and a majority (94.5%) “would use it at least in certain scenarios,” Vishal A. Patel, MD, and associates said in the Journal of Drugs in Dermatology.

Dermatologists aged 40 years and under were more likely to have used AI previously: 15% reported previous experience, compared with 4% of those over age 40 – but the difference in “age did not have a significant effect on perception of AI,” the investigators noted, adding that most of the dermatologists over 40 believe “that AI would be most beneficial and used for detection of malignant skin lesions.”

The survey also asked about ways the respondents would use AI to help their patients. Almost two-thirds of respondents (66%) chose analysis and management of electronic health records “for research purposes to improve patient outcomes,” compared with 56% who chose identifying unknown/screening skin lesions “with a list of differential diagnoses,” 32% who chose telemedicine, and 26% who chose primary surveys of skin, said Dr. Patel, director of cutaneous oncology at the George Washington University Cancer Center in Washington, and coauthors.

The respondents were fairly evenly split when asked about the possible impact of nondermatologists using AI in the near future to detect skin lesions, such as melanomas, on the need for dermatologists. Just over a quarter said that the need for dermatologists will be decreased all (about 4.4%) or some (about 21.1%) of the time, and 24.4% said that the need will be increased, with the largest share (39.9%) of respondents choosing the middle ground: neither increased or decreased, the investigators reported.

The survey form was emailed to 850 members of the Orlando Dermatology, Aesthetic & Surgical Conference listserv, with responses accepted from April 13 to May 14, 2021. The investigators noted that the response rate was low enough to be a limiting factor, making selection bias “by those with a particular interest in the topic” a possibility.

No funding sources for the study were disclosed. Dr. Patel disclosed that he is chief medical officer for Lazarus AI, the other authors had no disclosures listed.

Have you experienced malpractice?

No, I’m not asking whether you have experienced litigation. I’m asking whether you, as a physician, have actually experienced substandard care from a colleague. I have heard many such experiences over the years, and mistreatment doesn’t seem to be getting any less frequent.

It seems to me that physicians may be especially prone to receiving substandard care. If true, there could be several explanations. The first is that, unlike the Pope, who has a dedicated confessor trained to minister to his spiritual needs, no one formally trains physicians to treat physicians. As a result, most of us feel slightly uneasy at treating other physicians. We naturally wish to keep our colleagues well, but at the same time realize that our clinical skills are being very closely scrutinized. What if they are found to be wanting? This discomfiture can make a physician treating a physician overly compulsive, or worse, overtly dismissive.

Second, we physicians are famously poor patients. We pretend we don’t need the advice we give others, to monitor our health and promptly seek care when something feels amiss. And, for the period during which we delay a medical encounter, we often attempt to diagnose and treat ourselves.

Sometimes we are successful, which reinforces this approach. Other times, we fail at being our own caregiver and present to someone else either too late, or with avoidable complications. In the former instance, we congratulate ourselves and learn nothing from the experience. In the latter, we may heap shame upon ourselves for our folly, and we may learn; but it could be a lethal lesson. In the worst scenario, our colleague gives in to frustration (or angst), and heaps even more shame onto their late-presenting physician patient.

Third, when we do submit to being a patient, we often demand VIP treatment. This is probably in response to our anxiety that some of the worst things we have seen happen to patients might happen to us if we are not vigilant to ensure we receive a higher level of care. But of course, such hypervigilance can lead to excessive care and testing, with all the attendant hazards, or alternatively to dilution of care if our caregivers decide we are just too much trouble.

Fourth, as a fifth-generation physician myself, I am convinced that physicians and physician family members are either prone to unusual manifestations of common diseases or unusual diseases, or that rare disease entities and complications are actually more common than literature suggests, and they simply aren’t pursued or diagnosed in nonphysician families.

No matter how we may have arrived in a position to need medical care, how often is such care substandard? And how do we respond when we suspect, or know, this to be the case? Are physicians more, or less, likely to take legal action in the face of it?

I certainly don’t know any statistics. Physicians are in an excellent position to take such action, because judges and juries will likely believe that a doctor can recognize negligence when we fall victim to it. But we may also be reluctant to publicly admit the way (or ways) in which we may have contributed to substandard care or outcome.

Based on decades of working with physician clients who have been sued, and having been sued myself (thus witnessing and also experiencing the effects of litigation), I am probably more reluctant than normal patients or physicians to consider taking legal action. This, despite the fact that I am also a lawyer and (through organized medicine) know many colleagues in all specialties who might serve as expert witnesses.

I have experienced serial substandard care, which has left me highly conflicted about the efficacy of my chosen profession. As a resident, I had my first odd pain condition and consulted an “elder statesperson” from my institution, whom I assumed to be a “doctor’s doctor” because he was a superb teacher (wrong!)

He completely missed the diagnosis and further belittled (indeed, libeled) me in the medical record. (Some years later, I learned that, during that period, he was increasingly demented and tended to view all female patients as having “wandering uterus” equivalents.) Fortunately, I found a better diagnostician, or at least one more willing to lend credence to my complaints, who successfully removed the first of several “zebra” lesions I have experienced.

As a young faculty member, I had an odd presentation of a recurring gynecologic condition, which was treated surgically, successfully, except that my fertility was cut in half – a possibility about which I had not been informed when giving operative consent. Would I have sued this fellow faculty member for that? Never, because she invariably treated me with respect as a colleague.

Later in my career after leaving academia, the same condition recurred in a new location. My old-school gynecologist desired to do an extensive procedure, to which I demurred unless specific pathology was found intraoperatively. Affronted, he subjected me to laparoscopy, did nothing but look, and then left the hospital leaving me and the PACU nurse to try to decipher his instructions (which said, basically, “I didn’t find anything; don’t bother me again.”). Several years of pain later, a younger gynecologist performed the correct procedure to address my problem, which has never recurred. Would I have sued him? No, because I believe he had a disability.

At age 59, I developed a new mole. My beloved general practitioner, in the waning years of his practice, forgot to consult a colleague to remove it for several months. When I forced the issue, the mole was removed and turned out to be a rare pediatric condition considered a precursor to melanoma. The same general practitioner had told me I needn’t worry about my “mild hypercalcemia.”

Ten years later I diagnosed my own parathyroid adenoma, in the interim losing 10% of my bone density. Would I have sued him? No, for he always showed he cared. (Though maybe, if I had fractured my spine or hip.)

If you have been the victim of physician malpractice, how did you respond?

Do we serve our profession well by how we handle substandard care – upon ourselves (or our loved ones)?

The first condom specifically designed for use during anal sex has gained Food and Drug Administration approval.

Anal intercourse is considered to be much riskier than vaginal sex for the transmission of infections such as HIV and HPV, a risk factor for anal cancer, agency officials said in a statement Feb. 23 announcing the decision. And though the Centers for Disease Control and Prevention has long encouraged the use of a condom during anal intercourse, the FDA had not until now deemed this practice safe.

The latex ONE Male Condom, from prophylactic maker Global Protection Corp. of Boston, has already been available for vaginal sex. The FDA action now allows the company to market the product for anal intercourse.

“This authorization helps us accomplish our priority to advance health equity through the development of safe and effective products that meet the needs of diverse populations,” Courtney Lias, PhD, the director of the FDA’s Office of GastroRenal, ObGyn, General Hospital, and Urology Devices, said in a statement.

The FDA said it relied on an Emory University clinical study of condom safety of more than 500 men. Those who took part in the study were evenly divided between men who have sex with men and men who have sex with women. The condom failure rate, meaning that a condom either broke or slipped, was less than 1% during anal sex. The failure rate was 3 times higher during vaginal intercourse.

The Emory researchers also found that roughly 70% of men who have sex with men would be more likely to use condoms marked as safe for anal sex, according to a survey of 10,000 people.

ONE Male Condoms sell for between $3.48 for a three-pack and $14.48 for a 24-pack, according to Milla Impola, Global Protection’s director of marketing and communications. The FDA said the condom should be used with a condom-compatible lubricant when used during anal sex.

When counseling patients with warts, Adam Friedman, MD, admits that he feels like a character from “Game of Thrones” since many treatment options are “medieval and painful,” from duct tape occlusion to the stings of liquid nitrogen and salicylic acid.

“We can combine destructive, immunologic, and cytotoxic approaches,” Dr. Friedman, professor and chair of dermatology at George Washington University, Washington, said at the ODAC Dermatology, Aesthetic & Surgical Conference. “It’s not one or the other, we want to be aggressive. Combining therapies in the office and at home will accelerate clearance of warts; monotherapy just doesn’t cut it.”

At the initial clinic visit, he advises asking patients how long the warts have been present, because sometimes they will go away within a year or two without treatment. “If someone says, ‘I’ve had these for years,’ you know you’re in for the long haul and you have to be aggressive with their therapy,” Dr. Friedman said. “Sometimes you’ll pick up plantar warts on a full-body skin exam and the patient may say, ‘I really don’t care. Please don’t touch them,’ so it’s important to understand how they are impacting quality of life.”

Patients should also be asked what treatments they have used previously, and it is important to set some realistic expectations and dispel some myths, Dr. Friedman said. “One of the most important things is that you must get these patients back. This is not often a one and done approach; you need to keep hitting them [with therapy], because if you let one infected keratinocyte survive, it’s going to come back and it’s still going to be contagious – more likely for that patient than for anyone else.”

The application of liquid nitrogen is a popular, inexpensive destructive treatment option, with spray canisters that cost about $600. “You have to consider the temperature of the liquid nitrogen spray because melanocytes die at negative 5 degrees Celsius, so you have to be mindful in patients with darker skin tones that you may leave with permanent dyschromia, meaning hypopigmentation or depigmentation when you do this,” he said. Because it is painful, “we’re limited when it comes to treating children with warts who are younger than 9 or 10. I don’t think the Q-tip method or dipping a hemostat in cryogen and touching the tip really works. You’ve got to create a nice ice ball that thaws and kills the infected keratinocytes.”

Dr. Friedman favors a 10-second freeze of the wart, usually for two to three cycles depending on its anatomic location, and he may give patients imiquimod or 5-FU to use at home for 5 nights of the week. A recently published study found that the use of ultrasound gel increases the efficacy of cryotherapy in the treatment of warts.

Another destructive treatment approach is cantharidin 0.7% applied topically in the office. It is believed to activate neutral serine proteases that cause degeneration of the desmosomal plaque, leading to detachment of tonofilaments from desmosomes. Repeat in-office applications within 14-21 days may be necessary for this treatment, which is not approved by the Food and Drug Administration. “It is painless on application unless there’s a break in the skin,” Dr. Friedman said.

For warts on thicker areas such as palms and soles, he often employs combination therapy with cantharidin 1%, salicylic acid 30%, and podophyllotoxin 5%. “This can hurt a little bit, but some patients require only one treatment for cure,” he said. “Efficacy depends on the size of the wart.”

VP-102, a proprietary, drug-device combination product containing cantharidin, 0.7% “is coming down the pike,” Dr. Friedman said. “From the data we have, it seems that pairing with a curette or a #15 blade first gets better penetration, which makes sense. Patients come back every 3-4 weeks for treatment. It is a big investment, but it is worth it. I tell patients it’s not worth starting if you’re not going to see it through. I tell them, ‘we’re going to see a lot of each other until this is clear.’ ”

As for immunomodulatory approaches, imiquimod 5% cream is approved for treating genital and perianal warts. In Dr. Friedman’s clinical experience, it has limited efficacy on keratinized skin unless the surface has been disrupted, “so don’t even waste your time unless you are using some approach to enhance skin penetration,” he advised. “Insurance coverage can be a challenge,” he added.

He recommends application with salicylic acid alternating with imiquimod 5% cream every night at bedtime – under occlusion for thicker skinned areas.

For patients who favor use of natural products, off-label ingenol mebutate is an option. A case series of its use in 17 patients with anogenital warts found that 16 experienced clearance of all warts treated with either 0.05% or 0.015% ingenol mebutate gel. Local irritation occurred within 24-48 hours and lasted 2-5 days.

A natural alternative treatment is Candida albicans skin test antigen (Candin), especially for cases of multiple lesions on the hands and feet, because a field effect can be achieved, Dr. Friedman said. “The idea here is simple. At most, you’re talking about injecting a sentinel wart with 0.3 mL Candin 2-10 times every 3 weeks. The wart may be in a field of warts. That will induce an immune reaction that brings in the cavalry. I find that it works very well but it is painful, so when you’re injecting the feet, get the foot positioned well, because that patient may inadvertently kick you in the face [upon injection].”

Authors of a recent systematic review and meta-analysis highlighted the efficacy for systemic retinoids in the treatment of warts, particularly recalcitrant or recurrent types (Dermatol Ther 2021 34[2]:e14793). “Tazarotene is going to be your best bet if you can get it,” Dr. Friedman said. “If you have to go lower like OTC adapalene or tretinoin, be my guest, but tazarotene works best by slowing down that rapid turnover that the virus is imparting on the basal keratinocyte layer. It can enhance penetration of drug but also thin the warts out.”

Dr. Friedman characterized human papilloma virus (HPV) vaccines, such as Gardasil 9, as “one of the greatest innovations” in the treatment of warts. While indicated as a preventive strategy, “it also works as treatment. I’ve had patients with recalcitrant genital warts who will clear after taking the vaccine. It is something to think about as an adjuvant to everything we do, because it can function as a treatment.”

Another immunologic treatment option is the oral H2-receptor antagonist cimetidine taken 30 mg/kg per day for 3-5 months. “There is mixed evidence of efficacy with this,” Dr. Friedman said. “I tend to use it in cases of innumerable flat warts.”

As for cytotoxic options for treating warts, bleomycin works at 250-1,000 U/mL injected per lesion, with lidocaine. “This is painful to patients both on application and post treatment,” he said. “But it works really well when used properly.”

In one study of 46 patients who received intralesional bleomycin, 74% patients had complete resolution of all warts with an average of 1.7 treatments. About 70% of patients experienced pain that lasted less than 2 days after treatment. In a separate study of patients treated with bleomycin for warts, researchers in India diluted bleomycin with lidocaine to help mitigate some of that pain.

An additional cytotoxic option, 5-FU in formulations of 5% cream/solution or 1% cream, can effectively treat warts. Dr. Friedman typically suggests application to the affected area twice daily for 3-5 weeks. “The cost can be high especially for off-label use,” he said. He noted that Skin Medicinals makes a compounded wart solution composed of 5% 5-FU and salicylic acid 30% solution. A 50 mL container sells for about $50.

Dr. Friedman had no relevant disclosures related to his presentation.

When counseling patients with warts, Adam Friedman, MD, admits that he feels like a character from “Game of Thrones” since many treatment options are “medieval and painful,” from duct tape occlusion to the stings of liquid nitrogen and salicylic acid.

“We can combine destructive, immunologic, and cytotoxic approaches,” Dr. Friedman, professor and chair of dermatology at George Washington University, Washington, said at the ODAC Dermatology, Aesthetic & Surgical Conference. “It’s not one or the other, we want to be aggressive. Combining therapies in the office and at home will accelerate clearance of warts; monotherapy just doesn’t cut it.”

At the initial clinic visit, he advises asking patients how long the warts have been present, because sometimes they will go away within a year or two without treatment. “If someone says, ‘I’ve had these for years,’ you know you’re in for the long haul and you have to be aggressive with their therapy,” Dr. Friedman said. “Sometimes you’ll pick up plantar warts on a full-body skin exam and the patient may say, ‘I really don’t care. Please don’t touch them,’ so it’s important to understand how they are impacting quality of life.”

Patients should also be asked what treatments they have used previously, and it is important to set some realistic expectations and dispel some myths, Dr. Friedman said. “One of the most important things is that you must get these patients back. This is not often a one and done approach; you need to keep hitting them [with therapy], because if you let one infected keratinocyte survive, it’s going to come back and it’s still going to be contagious – more likely for that patient than for anyone else.”

The application of liquid nitrogen is a popular, inexpensive destructive treatment option, with spray canisters that cost about $600. “You have to consider the temperature of the liquid nitrogen spray because melanocytes die at negative 5 degrees Celsius, so you have to be mindful in patients with darker skin tones that you may leave with permanent dyschromia, meaning hypopigmentation or depigmentation when you do this,” he said. Because it is painful, “we’re limited when it comes to treating children with warts who are younger than 9 or 10. I don’t think the Q-tip method or dipping a hemostat in cryogen and touching the tip really works. You’ve got to create a nice ice ball that thaws and kills the infected keratinocytes.”

Dr. Friedman favors a 10-second freeze of the wart, usually for two to three cycles depending on its anatomic location, and he may give patients imiquimod or 5-FU to use at home for 5 nights of the week. A recently published study found that the use of ultrasound gel increases the efficacy of cryotherapy in the treatment of warts.

Another destructive treatment approach is cantharidin 0.7% applied topically in the office. It is believed to activate neutral serine proteases that cause degeneration of the desmosomal plaque, leading to detachment of tonofilaments from desmosomes. Repeat in-office applications within 14-21 days may be necessary for this treatment, which is not approved by the Food and Drug Administration. “It is painless on application unless there’s a break in the skin,” Dr. Friedman said.

For warts on thicker areas such as palms and soles, he often employs combination therapy with cantharidin 1%, salicylic acid 30%, and podophyllotoxin 5%. “This can hurt a little bit, but some patients require only one treatment for cure,” he said. “Efficacy depends on the size of the wart.”

VP-102, a proprietary, drug-device combination product containing cantharidin, 0.7% “is coming down the pike,” Dr. Friedman said. “From the data we have, it seems that pairing with a curette or a #15 blade first gets better penetration, which makes sense. Patients come back every 3-4 weeks for treatment. It is a big investment, but it is worth it. I tell patients it’s not worth starting if you’re not going to see it through.

If you worry that artificial intelligence (AI) will one day replace your own clinical acumen as a dermatologist, Vishal A. Patel, MD, advises you to think differently.

“AI is meant to be an enhancement strategy, a support tool to improve our diagnostic abilities,” Dr. Patel, a Mohs surgeon who is director of cutaneous oncology at the George Washington University Cancer Center, Washington, said during the ODAC Dermatology, Aesthetic & Surgical Conference. “Dermatologists should embrace AI and drive how it is utilized – be the captain of the plane (technology) and the passenger (patient). If we’re not in the forefront of the plane, we’re not to be able to dictate which way we are going with this.”

In 2019, a group of German researchers found that AI can improve accuracy and efficiency of specialists in classifying skin cancer based on dermoscopic images. “I really do believe this is going to be the future,” said Dr. Patel, who was not involved with the study. “Current research involves using supervised learning on known outcomes to determine inputs to predict them. In dermatology, think of identifying melanoma from clinical or dermoscopic images or predicting metastasis risk from digitized pathology slides.”

However, there are currently no universal guidelines on how large an AI dataset needs to be to yield accurate results. In the dermatology literature, most AI datasets range between 600 and 14,000 examples, Dr. Patel said, with a large study-specific variation in performance. “Misleading results can result from unanticipated training errors,” he said.

“The AI network may learn its intended task or an unrelated situational cue. For example, you can use great images to predict melanoma, but you may have an unintended poor outcome related to images that have, say, a ruler inside of them clustered within the melanoma diagnoses.” And unbeknown to the system’s developer, “the algorithm picks up that the ruler is predictive of an image being a melanoma and not the pigmented lesion itself.” In other words, the algorithm is only as good as the dataset being used, he said. “This is the key element, to ask what the dataset is that’s training the tool that you may one day use.”
 

Convolutional neural network

In 2017, a seminal study published in Nature showed that for classification of melanoma and epidermal lesions, a type of AI used in image processing known as a convolutional neural network (CNN) was on par with dermatologists and outperformed the average. For epidermal lesions, the network was one standard deviation higher above the average for dermatologists, while for melanocytic lesions, the network was just below one standard deviation above the average of the dermatologists. A CNN “clearly can perform well because it works on a different level than how our brains work,” Dr. Patel said.

In a separate study, a CNN trained to recognize melanoma in dermoscopic images was compared to 58 international dermatologists with varying levels of dermoscopy experience; 29% were “beginners,” with less than 2 years of experience; 19% were “skilled,” with 2-5 years of experience; and 52% were “experts,” with at least 5 years of experience. The analysis consisted of two experiments: In level I, dermatologists classified lesions based on dermoscopy only. In level II, dermatologists were provided dermoscopy, clinical images, and additional clinical information, while the CNN was trained on images only. The researchers found that most dermatologists were outperformed by the CNN. “Physicians of all different levels of training and experience may benefit from assistance by a CNN’s image classification,” they concluded.
 

Gene expression profiling

Another aspect of AI is gene expression profiling (GEP), which Dr. Patel defined as the evaluation of frequency and intensity of genetic activity at once to create a global picture of cellular function. “It’s AI that uses machine learning to evaluate genetic expression to assess lesion behavior,” he explained.

One GEP test on the market is the Pigmented Lesion Assay (PLA) from DermTech, a noninvasive test that looks at the expression of two genes to predict if a lesion is malignant or not. “Based on their validation set, they have shown some impressive numbers,” with sensitivities above 90%, and published registry data that have shown higher sensitivities “and even specificities above 90%,” he said.

“On the surface, it looks like this would be a useful test,” Dr. Patel said. A study published in 2021 looked at the evidence of applying real-world evidence with this test to see if results held up. Based on the authors’ analysis, he noted, “you would need a sensitivity and specificity of 95% to yield a positivity rate of 9.5% for the PLA test, which is what has been reported in real-world use. So, there’s a disconnect somewhere and we are not quite there yet.” That may be a result of the dataset itself not being as uniform between the validation and the training datasets, he continued. Also, the expression of certain genes is different “if you don’t have a clean input variable” of what the test is being used for, he added.

“If you’re not mirroring the dataset, you’re not going to get clean data,” he said. “So, if you’re using this on younger patients or for sun-damaged lesional skin or nonmelanocytic lesions around sun-damaged areas, there are variable expressions that may not be accurately captured by that algorithm. This might help explain the real-world variation that we’re seeing.”

Another GEP test in use is the 31-Gene Expression Profile Test for Melanoma, which evaluates gene expressions in melanoma tumors and what the behavior of that tumor may be. The test has been available for more than a decade “and there is a lot of speculation about its use,” Dr. Patel said. “A recent paper attempted to come up with an algorithm of how to use this, but there’s a lot of concern about the endpoints of what changes in management might result from this test. That is what we need to be thinking about. There’s a lot of back and forth about this.”

In 2020, authors of a consensus statement on prognostic GEP in cutaneous melanoma concluded that before GEP testing is routinely used, the clinical benefit in the management of patients with melanoma should be established through further clinical investigation. Dr. Patel recommended the accompanying editorial on GEP in melanoma, written by Hensin Tsao, MD, PhD, and Warren H. Chan, MS, in JAMA Dermatology.

In Dr. Patel’s opinion, T1a melanomas (0.8 mm, nonulcerated) do not need routine GEP, but the GEP test may be useful in cases that are in the “gray zone,” such as those with T1b or some borderline T2a melanomas (> 0.8 mm, < 1.2mm, nonulcerated, but with high mitosis, etc.); patients with unique coexisting conditions such as pregnancy, and patients who may not tolerate sentinel lymph node biopsy (SLNB) or adjuvant therapy.

Echoing sentiments expressed in the JAMA Dermatology editorial, he advised dermatologists to “remember your training and know the data. GEP predicting survival is not the same as SLNB positive rate. GEP should not replace standard guidelines in T2a and higher melanomas. Nodal sampling remains part of all major guidelines and determines adjuvant therapy.”

He cited the characterization of GEP in the editorial as “a powerful technology” that heralds the age of personalized medicine, but it is not ready for ubiquitous use. Prospective studies and time will lead to highly accurate tools.”

Dr. Patel disclosed that he is chief medical officer for Lazarus AI.

“AI is meant to be an enhancement strategy, a support tool to improve our diagnostic abilities,” Dr. Patel, a Mohs surgeon who is director of cutaneous oncology at the George Washington University Cancer Center, Washington, said during the ODAC Dermatology, Aesthetic & Surgical Conference. “Dermatologists should embrace AI and drive how it is utilized – be the captain of the plane (technology) and the passenger (patient). If we’re not in the forefront of the plane, we’re not to be able to dictate which way we are going with this.”

In 2019, a group of German researchers found that AI can improve accuracy and efficiency of specialists in classifying skin cancer based on dermoscopic images. “I really do believe this is going to be the future,” said Dr. Patel, who was not involved with the study. “Current research involves using supervised learning on known outcomes to determine inputs to predict them. In dermatology, think of identifying melanoma from clinical or dermoscopic images or predicting metastasis risk from digitized pathology slides.”

However, there are currently no universal guidelines on how large an AI dataset needs to be to yield accurate results. In the dermatology literature, most AI datasets range between 600 and 14,000 examples, Dr. Patel said, with a large study-specific variation in performance. “Misleading results can result from unanticipated training errors,” he said.

“The AI network may learn its intended task or an unrelated situational cue. For example, you can use great images to predict melanoma, but you may have an unintended poor outcome related to images that have, say, a ruler inside of them clustered within the melanoma diagnoses.” And unbeknown to the system’s developer, “the algorithm picks up that the ruler is predictive of an image being a melanoma and not the pigmented lesion itself.” In other words, the algorithm is only as good as the dataset being used, he said. “This is the key element, to ask what the dataset is that’s training the tool that you may one day use.”
 

Convolutional neural network

In 2017, a seminal study published in Nature showed that for classification of melanoma and epidermal lesions, a type of AI used in image processing known as a convolutional neural network (CNN) was on par with dermatologists and outperformed the average. For epidermal lesions, the network was one standard deviation higher above the average for dermatologists, while for melanocytic lesions, the network was just below one standard deviation above the average of the dermatologists. A CNN “clearly can perform well because it works on a different level than how our brains work,” Dr. Patel said.

In a separate study, a CNN trained to recognize melanoma in dermoscopic images was compared to 58 international dermatologists with varying levels of dermoscopy experience; 29% were “beginners,” with less than 2 years of experience; 19% were “skilled,” with 2-5 years of experience; and 52% were “experts,” with at least 5 years of experience. The analysis consisted of two experiments: In level I, dermatologists classified lesions based on dermoscopy only. In level II, dermatologists were provided dermoscopy, clinical images, and additional clinical information, while the CNN was trained on images only. The researchers found that most dermatologists were outperformed by the CNN. “Physicians of all different levels of training and experience may benefit from assistance by a CNN’s image classification,” they concluded.
 

Gene expression profiling

Another aspect of AI is gene expression profiling (GEP), which Dr. Patel defined as the evaluation of frequency and intensity of genetic activity at once to create a global picture of cellular function. “It’s AI that uses machine learning to evaluate genetic expression to assess lesion behavior,” he explained.

One GEP test on the market is the Pigmented Lesion Assay (PLA) from DermTech, a noninvasive test that looks at the expression of two genes to predict if a lesion is malignant or not. “Based on their validation set, they have shown some impressive numbers,” with sensitivities above 90%, and published registry data that have shown higher sensitivities “and even specificities above 90%,” he said.

“On the surface, it looks like this would be a useful test,” Dr. Patel said. A study published in 2021 looked at the evidence of applying real-world evidence with this test to see if results held up. Based on the authors’ analysis, he noted, “you would need a sensitivity and specificity of 95% to yield a positivity rate of 9.5% for the PLA test, which is what has been reported in real-world use. So, there’s a disconnect somewhere and we are not quite there yet.” That may be a result of the dataset itself not being as uniform between the validation and the training datasets, he continued. Also, the expression of certain genes is different “if you don’t have a clean input variable” of what the test is being used for, he added.

“If you’re not mirroring the dataset, you’re not going to get clean data,” he said. “So, if you’re using this on younger patients or for sun-damaged lesional skin or nonmelanocytic lesions around sun-damaged areas, there are variable expressions that may not be accurately captured by that algorithm. This might help explain the real-world variation that we’re seeing.”

Another GEP test in use is the 31-Gene Expression Profile Test for Melanoma, which evaluates gene expressions in melanoma tumors and what the behavior of that tumor may be. The test has been available for more than a decade “and there is a lot of speculation about its use,” Dr. Patel said. “A recent paper attempted to come up with an algorithm of how to use this, but there’s a lot of concern about the endpoints of what changes in management might result from this test. That is what we need to be thinking about. There’s a lot of back and forth about this.”

In 2020, authors of a consensus statement on prognostic GEP in cutaneous melanoma concluded that before GEP testing is routinely used, the clinical benefit in the management of patients with melanoma should be established through further clinical investigation. Dr. Patel recommended the accompanying editorial on GEP in melanoma, written by Hensin Tsao, MD, PhD, and Warren H. Chan, MS, in JAMA Dermatology.

In Dr. Patel’s opinion, T1a melanomas (0.8 mm, nonulcerated) do not need routine GEP, but the GEP test may be useful in cases that are in the “gray zone,” such as those with T1b or some borderline T2a melanomas (> 0.8 mm, < 1.2mm, nonulcerated, but with high mitosis, etc.); patients with unique coexisting conditions such as pregnancy, and patients who may not tolerate sentinel lymph node biopsy (SLNB) or adjuvant therapy.

Echoing sentiments expressed in the JAMA Dermatology editorial, he advised dermatologists to “remember your training and know the data. GEP predicting survival is not the same as SLNB positive rate. GEP should not replace standard guidelines in T2a and higher melanomas. Nodal sampling remains part of all major guidelines and determines adjuvant therapy.”

He cited the characterization of GEP in the editorial as “a powerful technology” that heralds the age of personalized medicine, but it is not ready for ubiquitous use. Prospective studies and time will lead to highly accurate tools.”

Dr. Patel disclosed that he is chief medical officer for Lazarus AI.

As COVID-19 cases and hospitalizations continue to decline across the United States, all states but one -- Hawaii -- have dropped their mask mandates or have announced plans to do so in coming weeks.

Retailers and cruises are following along, with Apple and Target stores lifting their own mask mandates this week. Cruise lines such as Norwegian and Royal Caribbean International have said mask requirements will be relaxed for vaccinated passengers, according to the Washington Post.

But guidance from the Centers for Disease Control and Prevention hasn’t changed even as the Omicron variant recedes across the country. Vaccinated people should wear masks when indoors in areas of “substantial or high transmission,” which still covers more than 95% of the country, according to a CDC map.

As daily cases continue to fall, the CDC is reviewing its recommendations, Rochelle Walensky, MD, the CDC director, said during a briefing last week.

“We want to give people a break from things like mask-wearing, when these metrics are better, and then have the ability to reach for them again should things worsen,” she said.

As states relax mask rules, county and city officials are now deciding what to do in their jurisdictions. Vaccinated residents in Los Angeles County may soon be able to go maskless in indoor settings that check for proof of vaccination, according to the Los Angeles Times.

Chicago will also end its mask and COVID-19 vaccine mandates for public places such as restaurants Feb. 28, according to the Chicago Tribune. Illinois will end a statewide indoor mask mandate on the same day. Masks will still be required in health care settings and public transmit.

State and local school boards are debating their mask policies as well. The Maryland State Board of Education voted Feb. 22 to allow local school districts to decide whether students must wear face coverings in school, according to the Associated Press. The update will take effect on March 1 if approved by a Maryland General Assembly committee that oversees the rule.

In New York, state officials have begun lifting mask rules. At the same time, 58% of New York voters want to see early March data before school mask mandates are ended, according to a new poll, released Feb. 22 by the Siena College Research Institute. About 45% of those polled said the state’s indoor public mask mandate should also still be in place.

The debate about wearing masks in schools will likely continue, especially as districts get caught between health authorities and parents, according to the Wall Street Journal. District officials in several states are receiving hundreds of emails daily from both sides, with parents calling for mask rules to end or saying that requirements should remain in place for now to keep kids safe.

American health care workers have remained resilient during the pandemic but are feeling the ongoing strain, with 23% saying they are likely to leave the field in the near future, according to a new poll.

About half of the respondents to the poll from USA Today/Ipsos reported feeling “burned out,” 43% said they were “anxious,” and 21% said they were “angry” about politics and abuse from patients and families.

“We’re trying to help people here, and we are getting verbally and physically abused for it,” Sarah Fried, a nurse in California who responded to the survey, told USA Today in a follow-up interview.

“Early in this pandemic, people were clapping for us and calling us heroes,” she said. “And what happened to that? What happened to them appreciating what nurses are doing?”

The poll was done Feb. 9-16 among 1,170 adults in the U.S. health care industry, including doctors, nurses, paramedics, therapists, home health aides, dentists, and other medical professionals.

A large majority of workers still reported being satisfied with their jobs, although that optimism has declined somewhat since early 2021 when the COVID-19 vaccine rollout was underway. About 80% of those in the recent poll said they were somewhat or very satisfied with their current job, which is down from 89% in an April 2021 poll from Kaiser Family Foundation/the Washington Post.

Most health care workers reported feeling “hopeful” (59%), “motivated” (59%), or “optimistic” (56%) about going to work. But “hopeful” is down from 76% and “optimistic” is down from 67%, compared with last year.

If they could pick a career over again, about 16% disagreed with the statement, “I would still decide to go into health care,” and 18% said they didn’t know how they felt about it.

“The pandemic has actually made me realize how important this career is and how I really do make a difference. I still love it,” Christina Rosa, a mental health counselor in Massachusetts, told USA Today.

During the pandemic, about 66% of those polled said they had treated a COVID-19 patient, which increased to 84% among nurses and 86% among hospital workers. Among those, 47% reported having a patient who died from COVID-19, including 53% of nurses and 55% of hospital workers.

What’s more, 81% of those who treated COVID-19 patients have cared for unvaccinated patients. Among those, 67% said their patients continued to express skepticism toward COVID-19 vaccines, and 38% said some patients expressed regret for not getting a vaccine. Beyond that, 26% said unvaccinated patients asked for unproven treatments, and 30% said the patient or family criticized the care they received.

Regarding coronavirus-related policy, most Americans working in health care expressed skepticism or criticism of the nation’s handling of the pandemic. About 39% agreed that the American health care system is “on the verge of collapse.”

Only 21% said the pandemic is mostly or completely under control. About 61% don’t think Americans are taking enough precautions to prevent the spread of the coronavirus.

Health care workers were slightly positive when it comes to the Centers for Disease Control and Prevention (54% approve, 34% disapprove), divided on the Biden administration (41% approve, 40% disapprove), and critical of the news media (20% approve, 61% disapprove) and the American public (18% approve, 68% disapprove).

Broadly, though, health care workers support public health efforts. About 85% back measures that provide N95 masks, and 83% back measures that provide COVID-19 tests.

Big Vegetable has lied to us all

Hear this, children of the world: Your parents have betrayed you. They tell you day in and day out that vegetables are necessary, that they’re healthy, that you need them, but it is not the truth. Behind their foul taste is nothing but empty lies.

Okay, before we get a full-blown child rebellion on our hands, let’s reel things in. Eating vegetables has many benefits, and will help prevent many nasty medical conditions, such as diabetes or cancer. However, cardiovascular disease is not among them.

nneem/Pixabay

For their study published in Frontiers in Nutrition, researchers analyzed the diet, lifestyle, and medical history of nearly 400,000 U.K. adults over a 5-year period, finding that 4.5% developed heart disease and that the average adult consumed about 5 tablespoons of vegetables per day. Those who consumed the most vegetables had a reduction in heart disease incidence of about 15%, compared with those who ate the least.

Hang on, you’re thinking, we just said that vegetables didn’t prevent cardiovascular disease. But the data show otherwise! Ah, but the data are unadjusted. Once the researchers took socioeconomic status, information level, and general lifestyle into account, that benefit disappeared almost completely. The benefit seems to come not from the vegetables themselves, but from being able to afford better food and medical care in general.

The researchers were quick to note the other benefits of eating vegetables, and that people should probably keep eating those five servings a day. But we’re onto you, scientists. You can’t fool us with your vegetable-based lies. Unless we’re talking about pizza. Pizza is the best vegetable.
 

The good old days of surgery?

Modern surgical instruments, techniques, and technological innovations are amazing. It’s hard to imagine what surgery was like before laparoscopes came along, or x-ray machines, or even anesthesia. But those days weren’t really that long ago. Modern anesthesia, after all, dates back to just 1846. We’ve got socks almost that old.

Petar Ubiparip/Pixabay

But suppose we go back even further … say 5,300 years. Older than the oldest sock. Scientists studying a funerary chamber in Burgos, Spain, which was built in the 4th millennium B.C., have come across what looks like “the first known radical mastoidectomy in the history of humankind,” Sonia Díaz-Navarro of the University of Valladolid (Spain) and associates wrote in Scientific Reports.

One of the skulls they uncovered shows signs of trepanation. “Despite the [evidence] of cut marks, it is difficult to conclude the type of tool used to remove the bone tissue, most likely a sharp instrument with a circular movement,” they investigators said.

What is clear, though, is that the patient survived the surgery, because there is evidence of bone regeneration at the surgical sites. Sites? “Based on the differences in bone remodelling between the two temporals, it appears that the procedure was first conducted on the right ear, due to an ear pathology sufficiently alarming to require an intervention, which this prehistoric woman survived,” they explained.

The same procedure was then performed on the left ear, “but whether this was performed shortly after the right ear, or several months or even years later can’t be concluded from the existing evidence,” IFL Science reported.

Located nearby was a small section of tree bark with some scratches on it. That, ladies and gentlemen, was the first prior authorization form.
 

I hate that song, with reason

Do you have a favorite song? You may have a million reasons for loving that song. And past research can tell you why. But it’s only in a recent study that researchers were able to tell you why you dislike a song. And you know the song we’re talking about.

MPI for Empirical Aesthetics

Dislike breaks down into three major categories of rationale: subject-related reasons (how the song makes you feel emotionally and/or physically), object-related reasons (the lyrics or composition), and social reasons (do you relate to this?). Researchers at the Max Planck Institute for Empirical Aesthetics in Frankfurt, Germany, interviewed 21 participants and asked them to come up with a prepared list of music that they disliked and why they didn’t like it. And there was a lot that they didn’t like: 277 dislikes worth, to be exact.

“The most often mentioned type of dislike was musical style, followed by artist and genre,” senior author Julia Merrill explained on Eurekalert. Just over 40% of those rationales for not liking the music just had to do with the music itself, but 85% involved the music combined with one of the other categories.

Social reasoning played a big part in dislike. If the listener didn’t feel like a part of the target in-group for the music or the music didn’t have the same social values as those of the listener, it had an impact on dislike, they said.

But our dislike of certain types of music doesn’t just separate us from people in a negative way. Looking at the dislike of certain types of music helps us define our terms of having good taste, the researchers explained. Saying that one type of music is better than another can bring us closer with like-minded people and becomes a piece of how we identify ourselves. Cue the music snobs.

So if you can blast Barry Manilow but can’t bring yourself to play the Rolling Stones, there’s a reason for that. And if you love Aretha Franklin but not Frank Sinatra, there’s a reason for that, too. It’s all very personal. Just as music is meant to be.

I hate that song, with reason

Do you have a favorite song? You may have a million reasons for loving that song. And past research can tell you why. But it’s only in a recent study that researchers were able to tell you why you dislike a song. And you know the song we’re talking about.

MPI for Empirical Aesthetics

Dislike breaks down into three major categories of rationale: subject-related reasons (how the song makes you feel emotionally and/or physically), object-related reasons (the lyrics or composition), and social reasons (do you relate to this?). Researchers at the Max Planck Institute for Empirical Aesthetics in Frankfurt, Germany, interviewed 21 participants and asked them to come up with a prepared list of music that they disliked and why they didn’t like it. And there was a lot that they didn’t like: 277 dislikes worth, to be exact.

“The most often mentioned type of dislike was musical style, followed by artist and genre,” senior author Julia Merrill explained on Eurekalert. Just over 40% of those rationales for not liking the music just had to do with the music itself, but 85% involved the music combined with one of the other categories.

Social reasoning played a big part in dislike. If the listener didn’t feel like a part of the target in-group for the music or the music didn’t have the same social values as those of the listener, it had an impact on dislike, they said.

But our dislike of certain types of music doesn’t just separate us from people in a negative way. Looking at the dislike of certain types of music helps us define our terms of having good taste, the researchers explained. Saying that one type of music is better than another can bring us closer with like-minded people and becomes a piece of how we identify ourselves. Cue the music snobs.

So if you can blast Barry Manilow but can’t bring yourself to play the Rolling Stones, there’s a reason for that. And if you love Aretha Franklin but not Frank Sinatra, there’s a reason for that, too. It’s all very personal. Just as music is meant to be.

Big Vegetable has lied to us all

Hear this, children of the world: Your parents have betrayed you. They tell you day in and day out that vegetables are necessary, that they’re healthy, that you need them, but it is not the truth. Behind their foul taste is nothing but empty lies.

Okay, before we get a full-blown child rebellion on our hands, let’s reel things in. Eating vegetables has many benefits, and will help prevent many nasty medical conditions, such as diabetes or cancer. However, cardiovascular disease is not among them.

For their study published in Frontiers in Nutrition, researchers analyzed the diet, lifestyle, and medical history of nearly 400,000 U.K. adults over a 5-year period, finding that 4.5% developed heart disease and that the average adult consumed about 5 tablespoons of vegetables per day. Those who consumed the most vegetables had a reduction in heart disease incidence of about 15%, compared with those who ate the least.

Hang on, you’re thinking, we just said that vegetables didn’t prevent cardiovascular disease. But the data show otherwise! Ah, but the data are unadjusted. Once the researchers took socioeconomic status, information level, and general lifestyle into account, that benefit disappeared almost completely. The benefit seems to come not from the vegetables themselves, but from being able to afford better food and medical care in general.

The researchers were quick to note the other benefits of eating vegetables, and that people should probably keep eating those five servings a day. But we’re onto you, scientists. You can’t fool us with your vegetable-based lies. Unless we’re talking about pizza. Pizza is the best vegetable.
 

The good old days of surgery?

Modern surgical instruments, techniques, and technological innovations are amazing. It’s hard to imagine what surgery was like before laparoscopes came along, or x-ray machines, or even anesthesia. But those days weren’t really that long ago. Modern anesthesia, after all, dates back to just 1846. We’ve got socks almost that old.

But suppose we go back even further … say 5,300 years. Older than the oldest sock. Scientists studying a funerary chamber in Burgos, Spain, which was built in the 4th millennium B.C., have come across what looks like “the first known radical mastoidectomy in the history of humankind,” Sonia Díaz-Navarro of the University of Valladolid (Spain) and associates wrote in Scientific Reports.

One of the skulls they uncovered shows signs of trepanation. “Despite the [evidence] of cut marks, it is difficult to conclude the type of tool used to remove the bone tissue, most likely a sharp instrument with a circular movement,” they investigators said.

What is clear, though, is that the patient survived the surgery, because there is evidence of bone regeneration at the surgical sites. Sites? “Based on the differences in bone remodelling between the two temporals, it appears that the procedure was first conducted on the right ear, due to an ear pathology sufficiently alarming to require an intervention, which this prehistoric woman survived,” they explained.

Acids peels are used to elicit a chemical exfoliation of the skin by hydrolyzing amide bonds between keratinocytes, reducing corneocyte adhesion, as well as inducing an inflammatory reaction stimulating tissue remodeling. Release of cytokines such as interleukin (IL)-1 and IL-6 by keratinocytes activates fibroblasts to increase the production of matrix metalloproteinases. These are involved in the production of hyaluronic acid and new collagen formation.

Mandelic acid was derived from bitter almonds (mandel is the German word for almond). It is a white powder originally used as an antibiotic for the treatment of urinary tract infections. Its antibacterial properties make it an excellent product for the topical treatment of acne, as well as for use in topical preparations to treat hyperpigmentation and photoaging. In cosmetic use, mandelic acid is a slow acting chemical peel that can be used in all skin types, including sensitive and rosacea-prone skin, as well as skin of color. Its large molecular size allows for the slow penetration of the acid on the skin and thus it can be carefully titrated.

Studies have shown its efficacy in reducing sebum content, acne, acne scarring, and hyperpigmentation. In clinical practice however, the most effective use of this acid is on sensitive skin. It is a great tool for clinicians to use as an effective exfoliant in less acid tolerant skin types. In commercially available concentrations of 5%-45%, mandelic acid can be used alone or in combination with other beta hydroxy peels, depending on the indication.

Most dermatologists and patients prefer in-office peels that induce noticeable peeling and resurfacing of the skin. Mandelic acid is one of the largest alpha hydroxy acids, a lipophilic acid that penetrates the skin slowly and uniformly, making it an ideal peel in sensitive or aging and thin skin types. Although many mandelic acid peels are available, however, there is a paucity of studies comparing their benefits and efficacies.

The Omicron subvariant, BA.2, is not only more transmissible than the original Omicron strain, BA.1, but may cause more severe disease, a lab study from Japan says.

“Our multiscale investigations suggest that the risk of BA.2 for global health is potentially higher than that of BA.1,” the researchers said in the study published on the preprint server bioRxiv. The study has not been peer-reviewed.

The researchers infected hamsters with BA.1 and BA.2. The hamsters infected with BA.2 got sicker, with more lung damage and loss of body weight. Results were similar when mice were infected with BA.1 and BA.2.

“Infection experiments using hamsters show that BA.2 is more pathogenic than BA.1,” the study said.

BA.1 and BA.2 both appear to evade immunity created by COVID-19 vaccines, the study said. But a booster shot makes illness after infection 74% less likely, CNN said.

What’s more, therapeutic monoclonal antibodies used to treat people infected with COVID didn’t have much effect on BA.2. 

BA.2 was “almost completely resistant” to casirivimab and imdevimab and was 35 times more resistant to sotrovimab, compared to the original B.1.1 virus, the researchers wrote. 

“In summary, our data suggest the possibility that BA.2 would be the most concerned variant to global health,” the researchers wrote. “Currently, both BA.2 and BA.1 are recognised together as Omicron and these are almost undistinguishable. Based on our findings, we propose that BA.2 should be recognised as a unique variant of concern, and this SARS-CoV-2 variant should be monitored in depth.”

If the World Health Organization recognized BA.2 as a “unique variant of concern,” it would be given its own Greek letter.

But some scientists noted that findings in the lab don’t always reflect what’s happening in the real world of people.

“I think it’s always hard to translate differences in animal and cell culture models to what’s going on with regards to human disease,” Jeremy Kamil, PhD, an associate professor of microbiology and immunology at Louisiana State University Health Shreveport, told Newsweek. “That said, the differences do look real.”

“It might be, from a human’s perspective, a worse virus than BA.1 and might be able to transmit better and cause worse disease,” Daniel Rhoads, MD, section head of microbiology at the Cleveland Clinic in Ohio, told CNN. He reviewed the Japanese study but was not involved in it.

Another scientist who reviewed the study but was not involved in the research noted that human immune systems are evolving along with the COVID variants. 

“One of the caveats that we have to think about, as we get new variants that might seem more dangerous, is the fact that there’s two sides to the story,” Deborah Fuller, PhD, a virologist at the University of Washington School of Medicine, told CNN. “Our immune system is evolving as well. And so that’s pushing back on things.”

Scientists have already established that BA.2 is more transmissible than BA.1. The Omicron subvariant has been detected in 74 countries and 47 U.S. states, according to CNN. About 4% of Americans with COVID were infected with BA.2, the outlet reported, citing the CDC, but it’s now the dominant strain in other nations.

It’s not clear yet if BA.2 causes more severe illness in people. While BA.2 spreads faster than BA.1, there’s no evidence the subvariant makes people any sicker, an official with the World Health Organization said, according to CNBC.
