Noninvasive treatment of cutaneous neurofibromas (cNFs): Results of a randomized prospective, direct comparison of four methods.

BACKGROUND: People with Neurofibromatosis Type 1 (NF1) suffer disfigurement and pain when hundreds to thousands of cutaneous neurofibromas (cNFs) appear and grow throughout life. Surgical removal of cNFs under anesthesia is the only standard therapy, leaving surgical scars. OBJECTIVE: Effective, minimally-invasive, safe, rapid, tolerable treatment(s) of small cNFs that may prevent tumor progression. METHODS: Safety, tolerability, and efficacy of 4 different treatments were compared in 309, 2-4 mm cNFs across 19 adults with Fitzpatrick skin types (FST) I-IV: radiofrequency (RF) needle coagulation, 755 nm alexandrite laser with suction, 980 nm diode laser, and intratumoral injection of 10 mg/mL deoxycholate. Regional pain, clinical responses, tumor height and volume (by 3D photography) were assessed before, 3 and 6 months post-treatment. Biopsies were obtained electively at 3 months. RESULTS: There was no scarring or adverse events > grade 2. Each modality significantly (P < .05) reduced or cleared cNFs, with large variation between tumors and participants. Alexandrite laser and deoxycholate were fast and least painful; 980 nm laser was most painful. Growth of cNFs was not stimulated by treatment(s) based on height and volume values at 3 and 6 months compared to baseline. LIMITATIONS: Intervention was a single treatment session; dosimetry has not been optimized. CONCLUSIONS: Small cNFs can be rapidly and safely treated without surgery.

Stimulant use in patients presenting with psychocutaneous disorders.

BACKGROUND: Psychocutaneous disorders are often attributed to stimulant medications, yet this relationship has never been fully elucidated. Literature on psychocutaneous disorders largely focuses on clinical presentation and treatment rather than disease etiology or exacerbation. OBJECTIVE: To determine whether patients presenting with psychocutaneous disorders display high rates of stimulant use and psychiatric comorbidity. METHODS: We undertook a retrospective cohort study of patients with psychocutaneous disorders presenting to a single center. It was hypothesized that these patients would have high rates of stimulant use and psychiatric comorbidity. Following analysis of baseline demographics, the patients were assigned to 1 of 2 groups: those with a psychotic disorder and those with a neurotic disorder. RESULTS: Sixty percent of the patients (n = 317) with psychocutaneous disease had recently used a stimulant and more than 80% (270 of 317) carried an additional psychiatric diagnosis. The neurotic disorder group (n = 237) was younger and had higher rates of stimulant use. The psychotic disorder group (n = 80) had higher rates of psychosis, medical comorbidity, and illicit stimulant drug use. LIMITATIONS: The predominantly Caucasian population may limit generalizability of findings as may the retrospective nature. CONCLUSIONS: Patients with psychocutaneous disease have high rates of stimulant use and most have at least 1 psychiatric comorbidity.

Social Media in Aesthetic Dermatology: Analysis of the Users Behind the Top Filler Posts.

BACKGROUND: Within the aesthetic realm, the influence of social media is quite prominent, with a growing percentage of patients using this technology to seek out health care recommendations and education. OBJECTIVE: To ascertain the most accurate representation of what our patients may encounter on social media, we sought to characterize the top posts on the most popular visually-based social media platform (Instagram). MATERIALS AND METHODS: We queried Instagram with variations of hashtags related to filler to determine which hashtags had the greatest number of posts associated with them. We then reviewed the top 100 posts associated with the top 9 hashtags, making note of whether the poster was a physician or nonphysician and whether an off-label procedure was performed or discussed. RESULTS: Most (85.6%) of the 900 reviewed posts were written by nonphysicians, and most (84.6%) of the posts focused on off-label procedures were posted by nonphysicians. Among the physician posters, the most common specialties were Plastic Surgery and Family Medicine, followed by Dermatology. CONCLUSION: At a time when patients are increasingly turning to social media for health care recommendations and education, most "top" content related to soft tissue augmentation is being provided by nonphysicians, many of whom are performing off-label procedures.

Morphea following treatment with pembrolizumab for melanoma with metastatic lymph nodes: case report and review of literature.

Pembrolizumab is a humanized IgG4 isotype mAb that the targets and blocks the programmed cell death protein 1 receptor on lymphocytes. Its use in treating metastatic melanoma is associated with increased overall survival compared to other older immunotherapies. Several adverse effects have been noted including both systemic and cutaneous manifestations. As a relatively novel treatment option, many new cutaneous manifestations are still being observed, occurring at various times after initiation of therapy. Previously noted cutaneous adverse effects include sarcoid-like reactions, rash, and changes in preexisting lesions or scars. Here we present a case in which biopsy-proven morphea developed after completion of pembrolizumab therapy.
