Male partners of infertile couples with congenital unilateral absence of the vas deferens are mainly non-azoospermic.

Background: Men with congenital unilateral absence of vas deferens were reported to be mainly azoospermic, with both unilateral renal absence and mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) but some have neither.

Objectives: To assess whether in infertile couples the male partners with congenital unilateral absence of vas deferens are mainly azoospermic men.

Material And Methods: Retrospective study in a unique university hospital; reproductive, clinical, CFTR analysis and seminal data of male partners of infertile couples (from 1998 to 2018) were analysed.

The spectrum of renal involvement in male patients with infertility related to excretory-system abnormalities: phenotypes, genotypes, and genetic counseling.

Background: While reproductive technologies are increasingly used worldwide, epidemiologic, clinical and genetic data regarding infertile men with combined genital tract and renal abnormalities remain scarce, preventing adequate genetic counseling.

Methods: In a cohort-based study, we assessed the prevalence (1995-2014) and the clinical characteristics of renal disorders in infertile males with genital tract malformation. In a subset of 34 patients, we performed a detailed phenotype analysis of renal and genital tract disorders.

[Value of neck dissection before definitive radiation therapy for locoregionally advanced squamous cell carcinoma of the head and neck].

Purpose: Optimal timing of neck dissection remains debated in the conservative management of patients with locoregionally advanced squamous cell carcinoma of the head and neck.

Patients And Methods: The files of 63 patients with radiographic evidence of bulky or necrotic nodal metastases treated by up-front neck dissection and definitive radiotherapy between 2000 and 2012 at two institutions were retrospectively reviewed.

Results: The primary site was oropharyngeal, hypopharyngeal or laryngeal in 63%, 21% and 13% cases, respectively.

Cystadenocarcinoma of the parotid: case report of a BRAF inhibitor treatment.

Background: Mutations of the proto-oncogene BRAF have been described in many cancers. Mutated BRAF causes overactive downstream signaling via MEK and ERK leading to excessive cell proliferation and survival. Their identification is of real interest because specific inhibitors have been developed.

[Clip migration after stereotactic macrobiopsy and presurgical localization: technical considerations and tricks].

Purpose: Clip migration occurs frequently in clinical practice (13-20%), irrespective of the approach. The purpose of this article is to suggest tricks in order to decrease clip migration and optimize presurgical localization.

Materials And Methods: Retrospective study of breast macrobiopsy from a lateral approach performed between March 2003 and June 2004: 447 clips were placed.
