Surgical treatment of hypospadias with lichen sclerosus: Long-term outcomes from a single center.

Background: Hypospadias with lichen sclerosus (LS) poses surgical challenges due to lack of materials for urethral reconstruction and coverage and the limited number of reports on this clinical condition.

Objectives: To report surgical strategies and outcomes for primary and redo hypospadias patients with LS.

Materials And Methods: We conducted a retrospective observational descriptive study with 31 patients with primary/redo hypospadias and LS between 2013 and 2023.

induces chemoresistance in colorectal cancer by inhibiting pyroptosis via the Hippo pathway.

Chemotherapy resistance is one of the main reasons for the poor prognosis of colorectal cancer (CRC). Moreover, dysbiosis of gut bacteria was found to be a specific environmental risk factor. In this study, enrichment of was elucidated to be significantly associated with CRC recurrence after chemotherapy.

Spindle cell metaplastic carcinoma of breast: A clinicopathological and immunohistochemical analysis.

Aim: To better characterize spindle cell metaplastic carcinoma (SpCMC) of breast, a rare variant of breast cancer that has been classified under the broad rubric of metaplastic carcinoma.

Methods: We presented herein 19 cases of metaplastic breast carcinoma with dominant spindle cell component. All cases were clinically of breast origin, showed more than 80% spindle morphology, 10 cases exhibited pure spindled morphology, 8 contained invasive ductal carcinoma (IDC) and 1 presented with ductal carcinoma in situ elements.

Two novel mutations on exon 8 and intron 65 of COL7A1 gene in two Chinese brothers result in recessive dystrophic epidermolysis bullosa.

Dystrophic epidermolysis bullosa is an inherited bullous dermatosis caused by the COL7A1 gene mutation in autosomal dominant or recessive mode. COL7A1 gene encodes type VII collagen - the main component of the anchoring fibrils at the dermal-epidermal junction. Besides the 730 mutations reported, we identified two novel COL7A1 gene mutations in a Chinese family, which caused recessive dystrophic epidermolysis bullosa (RDEB).

Human leukocyte antigen-G (HLA-G) expression in cervical lesions: association with cancer progression, HPV 16/18 infection, and host immune response.

Human leukocyte antigen-G (HLA-G) expression in 55 cervical intraepithelial neoplasia (CIN) patients with or without human papillomavirus (HPV) infection and 116 patients with squamous cell cervical cancer were examined using immunohistochemistry. Host immune response was assessed by estimating the number of intratumoral lymphocyte infiltration (TIL) in all lesions and counting CD57-expressing cells in the neoplasm lesions. The means of HLA-G immunoreactive scores were compared by the Mann-Whitney test and 1-way analysis of variance (ANOVA).
