简介：AbstractIntroduction:Scarring and non-scarring alopecias have rarely been described to occur together in the same patient. Distinguishing these two different types of alopecia is important as treatment and prognosis can be different.Case presentation:Here, we report the first case of simultaneous alopecia areata (AA) and central centrifugal cicatricial alopecia (CCCA) in a 35-year-old woman. New alopecic patches were noted on her frontal and vertex scalp. Biopsy of the frontal scalp revealed miniaturized hair follicles and dense lymphocytic infiltrate surrounding the hair bulbs, consistent with AA; while biopsy of the vertex scalp revealed decreased hair follicles, perifollicular fibroplasia with eccentric atrophy of the follicular epithelium, and premature desquamation of the inner root sheath at the level of the lower isthmus, consistent with CCCA.Discussion:Proposed mechanisms of these two alopecia types occurring together include loss of immune privilege, genetic predisposition, as well as unknown external factors that trigger an autoimmune lymphocytic response. Most recently, the peptidylarginine deiminase type III gene has been implicated in both diseases. Although treatment options can overlap between the two diseases, treatment response can differ and CCCA tends to have a worse prognosis.Conclusion:Awareness of this concomitant presentation of two alopecic types is important for appropriate treatment and prognostication.

简介：AbstractBackground:Gastroparesis is a debilitating medical condition with limited treatment options. Gastric per-oral pyloromyotomy (G-POEM) has emerged as a promising treatment option with remarkable short-term clinical success shown in multiple studies. While the post-procedure protocol is not standardized across many centers, the majority of the centers observes these patients in the hospital after the procedure for monitoring. In this single-center prospective study, we evaluated the safety and feasibility of same day discharge after the G-POEM procedure.Methods:All the patients with refractory gastroparesis undergoing G-POEM from October 2019 to March 2020 were enrolled. A total of 25 patients were enrolled in the procedure. Based on the pre-defined criteria, patients were either discharged on the same day after the procedure or admitted to the hospital for further observation. The patient and procedure-related data were extracted from the chart review. Univariate analysis was performed (chi-squared test) on categorical variables after organizing categorical variables as numeric counts or percentages. The student t test was performed on continuous variables after reporting as mean and standard deviation. For analysis with a smaller sample size, Fisher exact and Mann–Whitney tests were used.Results:A total of 25 patients were enrolled. The technical success of G-POEM was 100% and clinical success was 80% (20/25) at 1-month follow-up. Of the 25 patients, 9 patients (36%) were discharged on the same day according to the procedure from the recovery unit. Of the remaining 16 patients who were admitted to the hospital post-procedure, 10 (40%) were admitted due to procedure-related causes while other admissions were either pre-planned or due to social reasons. The average Charlson comorbidity index was lower in the same day discharge group (P < 0.05). The number of patients requiring double myotomy was higher in the same day discharge group (P < 0.05). The overall complication rate of G-POEM in the study cohort was 12% (3/25) with all complications being mild without any severe adverse events.Conclusion:G-POEM is a safe and effective method of treatment for refractory GP with higher clinical success in short-term follow-up. The same day discharge after G-POEM is safe and feasible in >50% of patients with close periprocedural monitoring.
