Successful Treatment of Immune Checkpoint Inhibitor-Induced Bullous Pemphigoid with Omalizumab: A Case Report and Review of the Literature.

Background: Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment by enhancing the immune system's ability to target cancer cells. However, ICIs can lead to immune-related adverse events (irAEs), including dermatologic manifestations such as bullous pemphigoid (BP).

Objective: To evaluate the efficacy and safety of omalizumab and other biologics in the treatment of ICI-induced refractory bullous pemphigoid and to derive a strategy for selecting biologic treatments for this condition.

Serum lipids may causally affect the occurrence of alopecia areata: A Mendelian randomization study.

Purpose: The etiology of alopecia areata (AA) in relation to serum lipids remains unclear, thereby prompting our intention to do Mendelian study on this subject.

Design: Two-sample Mendelian randomization (MR) analysis was performed in the study. The inverse variance-weighted method was used as the primary method.

Tacrolimus reverses pemphigus vulgaris serum-induced depletion of desmoglein in HaCaT cells via inhibition of heat shock protein 27 phosphorylation.

Background: Glucocorticoids are the first-line treatment for Pemphigus vulgaris (PV), but its serious side effects can be life-threatening for PV patients. Tacrolimus (FK506) has been reported to have an adjuvant treatment effect against PV. However, the mechanism underlying the inhibitory effect of FK506 on PV-IgG-induced acantholysis is unclear.

A Case of Chromoblastomycosis Caused by Fonsecaea pedrosoi Successfully Treated by Oral Itraconazole Together with Terbinafine.

Patients with chromoblastomycosis (CBM) usually have a history of local skin damage related to outdoor activities, mainly manifested as chronic refractory proliferative pathologic changes. We report a case of a 56-year-old man with CBM, identified as Fonsecaea pedrosoi infection by fungal culture and gene sequencing. This patient was successfully treated with a regimen of oral itraconazole (ITZ) and terbinafine lasting 7 months.

High-throughput sequencing reveals the diversity of TCR β chain CDR3 repertoire in patients with severe acne.

Acne is a common chronic inflammatory skin disease, and the inflammation immune response runs through all stages of acne lesions. In this study, we use a combination of multiplex-PCR and high-throughput sequencing technologies to analyze T cell receptor β chain CDR3 (complementarity-determining region 3) in peripheral blood isolated from severe acne patients. Once compared with healthy controls, we propose to identify acne-relevant CDR3 peptides.

A Novel Nested Real-time Polymerase Chain Reaction for Treponema pallidum DNA in Syphilis Biospecimens.

Background: Early diagnosis of Treponema pallidum infection is helpful for disease management, and conventional PCR is suitable for lesion swabs of patients with probable early syphilis. We thus tested nested and real-time PCR (NR-PCR) in various biosamples from syphilitic patients.

Methods: Samples were collected from syphilis patients before treatment.

Over reporting of congenital syphilis in Guangzhou, China.

The purpose of this study was to evaluate the rationality of congenital syphilis (CS) cases reported by physicians in hospitals of various levels in Guangzhou, China. The over-reporting rate was calculated. The results suggested that 49.
