There is a growing interest in the use of medical cannabis for a variety of dermatologic conditions. Despite the lack of evidence to validate the effectiveness and safety of marijuana, it is approved ...to treat a variety of dermatologic conditions in the United States. Furthermore, medical cannabis dispensaries have been making unsubstantiated claims about medical cannabis. It is important for dermatologists to know about the purported use of medical cannabis to help patients navigate this new treatment option, particularly as cannabis becomes legal in Canada in October 2018. We collected and tabulated the dermatologic indications for medical cannabis from Canada, the United States, and Europe. In the United States, dermatologic-approved indications vary by state but include psoriasis, lupus, nail-patella syndrome, and severe pain. Health Canada has listed psoriasis, dermatitis, and pruritus as potential therapeutic uses for cannabis but does not endorse its use for therapeutic purposes. We also surveyed the websites of dispensaries in Canada, the United States, and Europe and found that numerous unsubstantiated claims were being made and advertised to consumers. Dermatologic uses of medical cannabis, as claimed by dispensaries, included treating acne, aging, allergic contact dermatitis, chronic pain, herpes, dermatitis, lupus, Lyme disease, nevi, psoriasis, epidermolysis bullosa, and melanoma. Psoriasis, dermatitis, and chronic pain were the most commonly cited indications for medical cannabis listed by dispensaries. Our data indicate that the suggested and advertised uses of medical cannabis are largely unsubstantiated. Further research is necessary to validate the indications, effectiveness, and safety of medical cannabis.

Bullous pemphigoid is an acquired autoimmune subepidermal blistering disease that can arise following exposure to systemic medication, referred to as drug-induced bullous pemphigoid. Drug-induced ...bullous pemphigoid is a rare but potentially serious immune-related adverse event that should be considered in patients with advanced malignancies undergoing immunotherapy, with immune checkpoint inhibitors emerging in particular as a well-documented drug association in drug-induced bullous pemphigoid. We present a 74-year-old female with recurrent metastatic programmed cell death-ligand 1–positive squamous cell carcinoma of the head and neck area who developed drug-induced bullous pemphigoid in the setting of immunotherapy with a novel immunoglobulin-like transcript 4 inhibitor (MK-4830) in combination with pembrolizumab. Treatment with upadacitinib, a Janus-associated kinase-1 inhibitor, was pursued for significantly disabling disease that was recalcitrant to standard therapies and ultimately transition to palliative care. Follow-up at 4 weeks demonstrated good response. This is the first report describing the use of a Janus-associated kinase inhibitor for the treatment of bullous pemphigoid.
Introduction
Hidradenitis Suppurativa (HS) is a chronic inflammatory disordercommonly affecting body folds. It can significantly impair quality of life due to the physical, psychological, and ...socialturmoil experienced by patients. Treatment remains a challenge.Limited data on the HS patient experience, such as self-treatment exists.
Methods
This was a single-center cross-sectional study, utilizing a paper-based survey. Surveys were mailed out to all HS patients from the dermatology clinic and completed on a voluntary basis. Demographics, disease characteristics, medical and family history, treatments tried, and life quality were documented.
Results
The response rate was 49.4% (41/83), with a female predominance (26/41). Eighty-five percent (35/41) were Caucasian with an average age and BMI of 39.0 ± 16.78 and 30.71 ± 7.02, respectively. In total, 24.4% (10/41), 56.0% (23/41), and 19.5% (8/41) had Hurley I, II, and III, respectively. Lesions affected the genital region (75.6%), thigh/groin (68.2%), and axilla (46.3). Almost half (49%) of patients experienced an average of 1-2 flares per month. The most bothersome symptoms were pain (92.7%), discharge (68.3%), malodor (63.4%), and itch (61%). Depression (53.7%), severe facial acne (14.6%), and hypertension (14.6%) were the most common co-morbidities. Treatments used included antibiotics (82.9%) and surgical excision (34.2%) were. Over 90% of patients reportedself-treatment of lesions by squeezing (80.5%), soaking (53.7%), and lancing (41.4%).
Conclusions
This study provides insight into the patient perspective of HS. We identify itch as a symptom that is not frequently associated with HS and reveal how commonly patients utilize various types of self-treatment in their experience of disease.

A Survey of Topical Cannabis Use in Canada Mahmood, Farhan; Lim, Megan M.; Kirchhof, Mark G.
Journal of cutaneous medicine and surgery,

Journal Article
Peer reviewed
Background
Since its legalization in Canada, cannabis use has expanded to include commercially available topical formations. Several scientifically unsupported claims regarding the therapeutic ...efficacy of topical cannabis are also being made. Developing an understanding of the consumer uses of topical cannabis is important for clinicians to provide appropriate counseling and inform potential areas of therapeutic development. We are examining the prevalence, purpose of use, and sources of information regarding topical cannabis in the Canadian population, with a focus on dermatologic uses.
Method
A cross-sectional, anonymous electronic, voluntary survey was developed to assess the use of topical cannabis amongst adults in Canada.
Results
Cannabis was used topically at least once by 24.3% of respondents who started the survey. The commonest form of topical cannabis were creams (26.2%). The most common dermatologic conditions being treated with topical cannabis included atopic dermatitis (25%), acne (19%), and anti-aging (16%); for non-dermatologic conditions, common uses were for joint stiffness or tendonitis (30%) and headaches and migraines (27%). Topical cannabis was reported to be most effective for joint stiffness and tendonitis, general muscular soreness, headaches, eczema, pruritus, acne, and psoriasis. Most respondents obtained and received information about topical cannabis from dispensaries.
Conclusion
Canadians use topical cannabis for a broad range of systemic and dermatologic purposes, most of which have limited evidence. Future clinical studies are required to elucidate the therapeutic efficacy and safety of topical cannabis. Dermatologists should screen their patients for topical cannabis use and be aware of the limited evidence of therapeutic potential.

Pyoderma gangrenosum is a challenging disease to manage, due in part to the lack of approved treatment therapies. Recently, the emergence of biologic agents has expanded treatment options, with ...tumour necrosis factor alpha inhibitors being the best supported in the literature. In our report, we present a 50-year-old female with pyoderma gangrenosum who was successfully treated with the anti-interleukin-17 biologic agent, secukinumab, after failing other systemic therapies.
