Background Hidradenitis suppurativa (HS) is a chronic inflammatory disorder that primarily affects women of childbearing age. There is a paucity of data on HS disease activity during menstruation, pregnancy, and menopause and the potential impact of HS on the method of delivery. Objective We aimed to characterize the natural history of HS symptoms during menses, pregnancy, and menopause. We also sought to evaluate the potential impact of HS on delivery method and whether there were delivery-related healing complications unique to women with HS. Methods An anonymous survey was distributed via social media to international HS support groups and patients at three HS specialty clinics in North America. Responses were collected from March to July 2019. Results A total of 279 respondents answered questions on disease changes during pregnancy. Menstruation caused worsening of HS symptoms in 76.7%, no change in 22.2%, and improvement in 1.1%. During pregnancy, the distribution between symptoms worsening (34.8%), having no change (28.7%), and improving (36.6%) was relatively even. After menopause, participants typically reported either worsening (39.5%) or no change (44.2%) in HS symptoms. Among respondents with anogenital HS involvement who delivered vaginally, 3.1% believed that HS interfered with vaginal delivery (VD), and 23.5% believed that VD caused an HS flare. Cesarean section (C-section) delivery was reported by 44.2% of participants. Ten participants reported that they were advised by their doctor to have a C-section instead of a VD because of severe anogenital HS. Of those who underwent a C-section, 33.9% reported that HS interfered with incision healing, and 51.2% reported developing new HS lesions in their C-section scar. Conclusion To our knowledge, this is the first study describing the potential influence of HS on a patient’s method of delivery. Multidisciplinary collaboration plays a pivotal role in developing individualized treatment and birth plans for pregnant women with HS.

While dietary triggers have been investigated in acne and other inflammatory follicular dermatoses, there is a paucity of data on diet and hidradenitis suppurativa (HS). We sought to identify exacerbating and alleviating foods in HS patients. An anonymous survey was distributed via HS Facebook support groups and in person at HS specialty clinics. Participants were asked to select all that apply from a list to indicate

Injection site reactions with biologic medications are encountered with variable frequency. Although there is no clear definition, they commonly manifest with pain and irritation at the injection site. Previously proposed reaction classification systems may be impractical or insufficient, and more intuitive nomenclature may benefit clinical dermatologists and patients. Negative injection experiences (NIE) are common reasons for biologic medication nonadherence. Here we provide clinical classifications and recommendations for mitigating these reactions. We categorized NIEs into the following: (a) physical, due to the needle and injection process, (b) irritant, related to properties of the injected solution, and (c) allergic, both immediate and delayed.

was difficult in the present case; melanotrichoblastoma with seborrheic keratosis was finally diagnosed on the basis of the pathological findings. Although pathological findings are the gold standard for the diagnosis of melanotrichoblastoma, we believe that dermoscopic features might help in the diagnosis of melanotrichoblastoma even in cases of coexistence with seborrheic keratosis.
