Bleeding lesion on nose
One week later, the pathologist reported that the growth was an amelanotic melanoma of 1.2 mm depth. The FP was relieved that he sent the tissue for pathology and did not assume this was a benign pyogenic granuloma. The patient was referred to a head and neck surgeon for complete excision with margins and a sentinel lymph node biopsy. She was fortunate to not have any nodal metastases. The FP performed a complete skin exam and found no other lesions suspicious for melanoma.

Newborn oral rotavirus vaccine held effective
A new oral rotavirus vaccine administered within the first few days of life appears effective against severe rotavirus gastroenteritis in newborns, a study has found.
Julie E. Bines, MD, from the RV3 Rotavirus Vaccine Program at the Murdoch Children’s Research Institute in Melbourne, and her coauthors reported the results of a double-blind, placebo-controlled phase 2b trial in 1,513 healthy newborns in Indonesia. Participants were randomized to three doses of oral human neonatal rotavirus vaccine either on a neonatal schedule (0-5 days, 8-10 weeks, and 14-16 weeks of age) or an infant schedule (8-10 weeks, 14-16 weeks, and 18-20 weeks of age), or the equivalent schedules of placebo.
That efficacy was 77% in those who received the doses on the infant schedule.
Overall, severe rotavirus gastroenteritis was reported in 5.6% of the placebo group, compared with 2.1% of the combined vaccine group. The time from randomization to first episode of gastroenteritis was significantly longer among participants who received the vaccine, compared with those who received placebo.
“The use of a neonatal dose was investigated in the early phase of development of the rotavirus vaccine but was not pursued because of concerns regarding inadequate immune responses and safety,” wrote Dr. Bines and her associates
They noted that the results of this trial compared favorably with the efficacy of licensed vaccines in similar low-income countries that experienced a high burden of rotavirus disease.
The rates of severe adverse events were similar across all the trial groups. There were no episodes of intussusception seen within the 21-day risk period after immunization, either in the vaccine or placebo groups. However, there was one episode of intussusception in a child on the infant schedule group, which occurred 114 days after the third dose of the vaccine.
“Because intussusception is rare in newborns, the administration of a rotavirus vaccine at the time of birth may offer a safety advantage,” Dr. Bines and her associates said.
The study was supported by the Bill and Melinda Gates Foundation, the National Health and Medical Research Council, PT Bio Farma, and the Victorian government’s Operational Infrastructure Support Program. Authors declared fees, grants, and institutional support from the study sponsors, and three authors also declared a stake in the patent of the RV3-BB vaccine, which is licensed to PT Bio Farma.

Pre–bariatric surgery weight loss improves outcomes
Preoperative weight loss improves bariatric surgery outcomes, according to findings from a single-institution retrospective analysis. The weight loss came from following a 4-week low-calorie diet (LCD) and was of greatest benefit to patients who lost 8% or more of their excess weight. These patients had a greater loss of excess weight in the 12 months following surgery, as well as shorter average hospital length of stay.
Preliminary studies indicated that short-term weight loss before surgery might reduce surgical complexity by reducing the size of the liver and intra-abdominal fat mass, but it remained uncertain what effect weight loss might have on long-term outcomes.
The LCD included 1,200 kcal/day (45% carbohydrates, 35% protein, 20% fat), which were consumed through five meal-replacement products and one food-based meal. Liquids included at least 80 ounces of calorie-free, caffeine-free, carbonation-free beverages per day. Patients were also instructed to conduct 30 minutes of moderate to vigorous activity per day.
Deborah A. Hutcheon, DCN, and her fellow researchers analyzed data from their own institution, where a presurgical 4-week LCD with a target loss of 8% or more of excess weight had been standard policy already. The population included 355 patients who underwent sleeve gastrectomy (n = 167) or Roux-en-Y gastric bypass (n = 188) between January 2014 and January 2016.
Almost two-thirds (63.3%) of patients achieved the target weight loss before surgery. There were some differences between the two groups. The group that achieved the target contained a greater proportion of men than did the other group (25.5% vs. 13.7%, respectively; P = .013), a higher proportion of white patients (84.8% vs. 74.1%; P = .011), and a higher proportion of patients taking antihypertensive medications (68.3% vs. 57.3%; P = .048). The two groups had similar rates of preoperative comorbidities and surgery types.
Those who achieved the target weight loss had a shorter hospital length of stay (1.8 days vs. 2.1 days; P = .006). They also had a higher percentage loss of excess weight at 3 months (42.3% vs. 36.1%; P less than .001), 6 months (56.0% vs. 47.5%; P less than .001), and at 12 months (65.1% vs. 55.7%; P = .003).
After controlling for patient characteristics, insurance status, 12-month diet compliance, and surgery type, successful presurgery weight loss was associated with greater weight loss at 12 months.

Basiliximab/BEAM may improve post-ASCT outcomes in PTCL
LA JOLLA, CALIF. – Combining a radio-labeled, anti-CD25, monoclonal antibody with BEAM chemotherapy appears to be an effective and safe conditioning regimen prior to autologous stem cell transplant in patients with peripheral T-cell lymphoma (PTCL), investigators report.
In a phase 1 trial, median progression-free survival (PFS) was 10.6 months for patients treated with the yttrium-90–labeled, chimeric, anti-CD25 antibody basiliximab (Simulect) at one of three dose levels plus standard dose BEAM (carmustine, etoposide, cytarabine, and melphalan), said Jasmine Zain, MD, of the City of Hope Medical Center in Duarte, Calif.
There have been no significant cases of delayed transplant engraftment or unexpected increases in either mucositis or infectious complications, she said at the annual T-cell Lymphoma Forum.
“With standard conditioning, I think the best outcome we have seen is that at 5 years we have about 45% to 50% event-free survival, depending on the histology,” she said. “So we’re hoping we will surpass that.”
The first patient to receive a transplant in the study was treated in July 2015, and since most relapses in this patient population tend to occur within 2 years of transplant, the investigators expect that they will get a better idea of the results in the near future, Dr. Zain said.
PTCL generally has a poor prognosis, and many centers have turned to high-dose therapy followed by autologous stem cell transplant as a consolidation strategy for patients who are in their first or subsequent complete remissions, as well as for patients with relapsed or refractory disease.
“We in this field consider autologous stem cell transplant to be not curative for PTCL. It is true that some patients will achieve long-term remission and even long-term survival,” she said. ”But overall, even with long-term data, it seems like most patients will eventually relapse.”
The goal of the ongoing study is to determine whether adding basiliximab to BEAM could improve outcomes in the long run.
Unlike ibritumomab tiuxetan (Zevalin) – an yttrium-90–labeled antibody that’s been combined with rituximab to target CD20 in relapsed or refractory low-grade follicular B-cell non-Hodgkin lymphoma – basiliximab is targeted to CD25, which is preferentially expressed on T cells.
Basiliximab has been shown to inhibit growth of human anaplastic large cell lymphoma (ALCL) tumors and improve survival in mice bearing human tumor xenografts.
Because the beta particles that basiliximab emits cannot be detected on conventional scans, the antibody is also labeled with an indium-111 radiotracer for purposes of tracking.
At the time of Dr. Zain’s presentation, 13 patients ranging from 19 to 77 years of age were enrolled in the phase 1 trial. The patients were assigned to receive basiliximab at a dose of either 0.4, 0.5, or 0.6 mCi/kg in combination with standard dose BEAM.
The first patient treated had delayed engraftment of platelets; all subsequent patients had engraftment as expected.
There were no grade 3 or 4 toxicities at any dose level and no treatment-related mortality. The most frequent toxicity was grade 2 stomatitis, which occurred in three patients each in the 0.4 and 0.6 miC/kg levels and in four patients at the 0.5 miC/kg level of basiliximab. There were no dose-limiting toxicities.
As of the data cutoff, three patients have experienced relapses, and two of those patients died from disease progression. The times from transplant to relapse were 301 days and 218 days in the two patients who died, and it was 108 days in the third patient.
Dose expansion is continuing in the study, with an additional seven patients scheduled for treatment at the 0.6 miC/kg dose, Dr. Zain said.
Dr. Zain did not report information on conflicts of interest. The study is supported by City of Hope Medical Center and the National Cancer Institute. The T-cell Lymphoma Forum is held by Jonathan Wood & Associates, which is owned by the same company as this news organization.

Treatment priorities often differ between RA patients, clinicians
Patients with RA and their clinicians approach treatment goals differently based on knowledge, illness experience, and competing priorities, according to findings from a qualitative study.
The results of this study underscore “the tension between having an explicit shared goal between clinicians and patients, and experiencing inherently different – and at times opposing – conceptualization of how one formulates or achieves said goal,” wrote Jennifer L. Barton, MD, of the Department of Veteran Affairs Portland Health Care System and Oregon Health & Science University, Portland, and her coauthors.
Two domains – disease knowledge and psychosocial dynamics – emerged across all focus groups, Dr. Barton and her colleagues reported in Arthritis Care & Research.
Disease knowledge and education
In the knowledge domain, themes that emerged were informed choice, medication adherence and safety, and clinician assumption of patients’ inability to interpret information. Patients disclosed, for instance, a desire for more information on disease progression and medication side effects to inform future clinician visits, and often sought such information on the Internet.
“Patients highlighted the importance of RA knowledge to understanding what was happening to them physically and the impact of medication on their bodies, and their need to seek information outside of the clinical visit,” the authors noted.
Whereas patients discussed medications in the context of informed decision making, “many clinicians connected RA education to risk of nonadherence and medication safety,” the authors reported. Additionally, “patients did not discuss their adherence to clinician treatment recommendations, though patients expressed dissatisfaction with clinicians who they believed dismissed their medication concerns.”
Some clinicians expressed frustration with patients’ self-education efforts and attitudes toward alternative medicine, and patients reported feeling as though doctors had “diminished the importance of information” they shared.
“Several clinicians voiced perceived paradoxes in current expectations of their professional role as an expert who also defers to patient preferences,” the authors said. “Many clinicians voiced frustration with patients seeking knowledge from what they considered unreliable sources, which prompted varying levels of comfort among clinicians with some adopting a more paternalistic stance.”
Psychosocial dynamics of RA illness
The psychosocial dynamics domain focused on stress and found that patients’ experiences with RA informed their treatment preferences and affected patient-provider communication. For instance, patients who experienced inability to participate in activities because of pain or fatigue prioritized treatment goals aimed at pain reduction and increased energy, with minimal side effects.
“In contrast, clinicians talked about using objective clinical markers” to inform treatment strategy, the authors said. Although they acknowledged the psychosocial stress experienced by patients, clinicians cited limited time and resources as a main reason for their inability to adequately address these concerns.
Both patients and clinicians acknowledged the role of fear in the disease experience, with providers asserting that patients’ fear “disrupted effective communication and complicated patient willingness to follow treatment recommendations,” the authors said.
Lastly, both patients and clinicians described treatment decisions as a “negotiation” in which patients’ priorities of quality of life improvements, such as pain reduction, often were at odds with objective clinical goals of the provider, such as addressing underlying damage.
“Patients indicated that clinician goals focused on objective clinical markers and helping patients achieve remission; however, patients expressed a desire for clinicians to look beyond clinical markers and consider patients’ quality of life goals as well as being open to multiple treatment possibilities,” the authors said.
Areas for improvement
The results of the study highlight potential areas for improvement in patient-clinician communication, namely by balancing the imparting of clinician knowledge with sincere consideration of patient preferences and priorities. “The mismatch in attitudes towards the goal of knowledge between patients and clinicians may lead to suboptimal communication and lack of trust,” the authors wrote. “Patients’ desire for information on a range of RA topics is important, but the value attached to that knowledge is where patients and clinicians diverge.”
Resources aimed at facilitating a conversation around goals may lead to greater goal concordance, which could potentially result in more high value treatment, the authors concluded. “With tools and training to support patient goal-directed care in rheumatology, improved outcomes and reduced disparities may be achieved.”
The study was funded by a grant to Dr. Barton from the National Institutes of Health.

Biologics have best chance of achieving PASI 90 in psoriasis
The biologics ixekizumab, secukinumab, brodalumab, guselkumab, certolizumab pegol, and ustekinumab provide the best chances for achieving Psoriasis Area and Severity Index (PASI) 90 when compared with placebo in patients with moderate to severe psoriasis, according to Emilie Sbidian, MD, and her associates.
Dr. Sbidian of Henri Mondor Hospital, Créteil, France, and her colleagues conducted a network meta-analysis of 109 randomized, controlled trials that collectively had a total of 39,882 participants. The results showed that all of the interventions appeared superior to placebo in terms of reaching PASI 90.
The investigators also found that there was no significant difference between the three anti–IL-17 agents (brodalumab, ixekizumab, and secukinumab) and the two anti–IL-23 (tildrakizumab and guselkumab) monoclonal antibodies in terms of reaching PASI 90. However, all of the anti–IL-17 drugs (brodalumab, ixekizumab, and secukinumab) and guselkumab (an anti–IL-23) were significantly more effective than three anti–TNF-alpha agents (infliximab, adalimumab, and etanercept).
Additionally, in the network meta-analysis, anti–IL-17 drugs were the best for achieving PASI 90, compared with placebo (RR, 30.81), followed by anti–IL-12/23 (RR, 23.16), anti–IL-23 (RR, 16.53), and anti–TNF-alpha (RR, 11.58). At the individual drug level, results showed ixekizumab was the best treatment for attaining PASI 90 when compared with placebo (RR, 32.45), followed by secukinumab (RR, 26.55), brodalumab (RR, 25.45), guselkumab (RR, 21.03), certolizumab pegol (RR, 24.58), and ustekinumab (RR, 19.91). The investigators found that “there was no significant difference between all of the interventions and the placebo regarding the risk of serious adverse effects.”
“Our main results do not reflect the way patients are managed in ‘real life,’ ” the researchers concluded. “Currently, biological treatments have been positioned as third-line therapies by regulatory bodies, with mandatory reimbursement criteria that patients must meet before being considered for these treatments (moderate to severe disease after failure, intolerance or contraindication to conventional systemic agents).”

VIDEO: SPF 100 sunscreen outperformed SPF 50 in Vail study
SAN DIEGO – a finding that might interest consumers and prompt the Food and Drug Administration to continue to allow sunscreens to have labels listing sun protection factors greater than 50.*
“Our study results show pretty definitively that SPF 100 did significantly better than SPF 50 in a real world environment,” Darrell S. Rigel, MD, said at the annual meeting of the American Academy of Dermatology.
Dr. Rigel cited data that he and his associates recently published from 199 adults skiing on a sunny March day in Colorado. Participants applied a blinded sunscreen rated at SPF 50 to one side of their face all day and an SPF 100 sunscreen to the other side all day, and the researchers then ran a blinded assessment of images taken of each side at the end of the day. The sunburn on the SPF 50 side exceeded the other side in 55% of skiers, the two sides matched in 40%, and in 5% the sunburn was worse on the SPF 100 side (J Am Acad Dermatol. 2017 Dec 29. doi: 10.1016/j.jaad.2017.12.062).
“The SPF 50 side of the face was 11 times more likely to be sunburned than the SPF 100 side,” and for all the secondary endpoints and different ways of analyzing the data, the SPF 50 was not as effective as SPF 100, Dr. Rigel said in a video interview. Erythema appeared on 41% of the SPF 50–treated sides of participants faces, compared with 14% of the sides treated with SPF 100 sunscreen.
The results followed-up on a report from Dr. Rigel and his associates from 8 years ago that ran a similar comparison of two sunscreen potencies, SPF 85 and SPF 50, in 56 skiers, with similar results showing greater sunburn protection from the higher SPF sunscreen (J Am Acad Dermatol. 2010 Feb;62[2]:348-9). In 2011, the FDA proposed a new rule for SPF labeling that would cap the maximum SPF potency possible of 50, which created a label 50+ to designate unspecified SPF above 50. According to Dr. Rigel, the FDA rejected his 2010 study as documentation of incremental benefit above SPF 50 because of several flaws the agency found with that study, including not tracking sunscreen use by weight. He specifically designed the new, 199-subject study to address that and the FDA’s other concerns.
He and his associates decided to do the study because the FDA said in the monograph that, if the concerns were met, “they would accept the study as definitive,” said Dr. Rigel, a dermatologist at New York University.
The greater protection from SPF 100 sunscreen probably occurs because it’s “more forgiving” when used with inadequate application, he suggested. Allowing labeling that specifies SPF levels greater than 50 would help consumers pick sunscreen formulations that give greater protection, and it would encourage manufacturers to market sunscreens with higher SPF levels.
Dr. Rigel has been a consultant to Castle Biosciences, DermTech, Ferndale, Myriad, Neutrogena, and Novascan and has received research support from Castle and Neutrogena.
Correction, 2/22/18: Due to an editing error, an earlier version of this article implied incorrectly that sunscreen labels listing SPFs over 50 had been banned .

EXPERT ANALYSIS FROM AAD 18
House cleaning linked to lung function decline
that has found accelerated decline in lung function among women regularly engaged in cleaning activities.
The longitudinal population-based cohort study, published online Feb. 16 in the American Journal of Respiratory and Critical Care Medicine, looked at the lung health of 6,230 people who were followed for more than 20 years as part of the European Community Respiratory Health Survey.
Analysis based on questionnaires about cleaning practices revealed that women who were responsible for cleaning at home or who worked as professional cleaners showed significantly greater declines in maximum forced vital capacity (FVC) and maximum forced expiratory volume in 1 second (FEV1), compared with women who said they did not regularly clean.
However, there was no association between cleaning practices in men – either professional or domestic – and accelerated lung function decline. The authors suggested that the exposures experienced by men who worked as cleaners may have been different from the exposures experienced by women. They also noted that the small numbers of male cleaners meant the study wasn’t powered to pick up greater declines in lung function.
The study also showed a significant association between use of cleaning products and decline in lung function. Women who used sprays or other cleaning agents at least once a week showed significantly greater declines in FEV1 and FVC, compared with women who didn’t use cleaning products. Again, this effect was not significant in men.
“One possible mechanism for the accelerated decline in cleaners is the repetitive exposure to low-grade irritative cleaning agents over time, thereby causing persistent changes in the airways,” the authors wrote. “Repeated exposure could lead to remodelling of the airways, thereby over time causing an accelerated decline in FVC and FEV1.”
The analysis found no significant increases in the incidence of chronic airway obstruction among regular cleaners, nor among those who used cleaning products. The authors noted that while previous studies had suggested an increase in chronic obstructive pulmonary disease among occupational cleaners, their study reported relatively few cases of COPD.
While the prevalence of asthma was slightly higher in the two groups of women exposed to regular cleaning (12.3% and 13.7%, versus 9.6%), adjustment for asthma in the analysis did not change the associations. This suggests that the declines in lung function seen in regular cleaners were not mediated by cleaning-related asthma, the researchers noted.

that has found accelerated decline in lung function among women regularly engaged in cleaning activities.
The longitudinal population-based cohort study, published online Feb. 16 in the American Journal of Respiratory and Critical Care Medicine, looked at the lung health of 6,230 people who were followed for more than 20 years as part of the European Community Respiratory Health Survey.
Analysis based on questionnaires about cleaning practices revealed that women who were responsible for cleaning at home or who worked as professional cleaners showed significantly greater declines in maximum forced vital capacity (FVC) and maximum forced expiratory volume in 1 second (FEV1), compared with women who said they did not regularly clean.
However, there was no association between cleaning practices in men – either professional or domestic – and accelerated lung function decline. The authors suggested that the exposures experienced by men who worked as cleaners may have been different from the exposures experienced by women. They also noted that the small numbers of male cleaners meant the study wasn’t powered to pick up greater declines in lung function.
The study also showed a significant association between use of cleaning products and decline in lung function. Women who used sprays or other cleaning agents at least once a week showed significantly greater declines in FEV1 and FVC, compared with women who didn’t use cleaning products. Again, this effect was not significant in men.
“One possible mechanism for the accelerated decline in cleaners is the repetitive exposure to low-grade irritative cleaning agents over time, thereby causing persistent changes in the airways,” the authors wrote. “Repeated exposure could lead to remodelling of the airways, thereby over time causing an accelerated decline in FVC and FEV1.”
The analysis found no significant increases in the incidence of chronic airway obstruction among regular cleaners, nor among those who used cleaning products. The authors noted that while previous studies had suggested an increase in chronic obstructive pulmonary disease among occupational cleaners, their study reported relatively few cases of COPD.
While the prevalence of asthma was slightly higher in the two groups of women exposed to regular cleaning (12.3% and 13.7%, versus 9.6%), adjustment for asthma in the analysis did not change the associations. This suggests that the declines in lung function seen in regular cleaners were not mediated by cleaning-related asthma, the researchers noted.
They also noted that the women who reported not engaging in any cleaning may represent a particular socioeconomic group, but adjustment for socioeconomic status did not alter the associations.
