Epidermal inclusion cyst in male breast: how to differentiate from other male breast lesions.

Male breast lesions are relatively less common. The most encountered malignant lesion in the male breast is ductal adenocarcinoma; and benign lesions are gynecomastia, fibrocystic disease, intramammary lymph node, fibroadenoma, lipoma and epidermal inclusion cyst (EIC), respectively [5,6]. To date, there had been published only a few cases of EIC of the male breast in literature [3,5,6].

Tracheal Stenosis After Prolonged Intubation Due to COVID-19.

Objectives: The authors aimed to evaluate the characteristics and management outcomes of patients who developed tracheal stenosis after invasive mechanical ventilation (IMV) due to COVID-19.

Design, Setting, And Participants: The data of 7 patients with tracheal stenosis and 201 patients without tracheal stenosis after IMV due to COVID-19 between March 2020 and October 2021 were retrospectively analyzed.

Interventions: Flexible bronchoscopy was performed for the diagnosis of tracheal stenosis and the evaluation of the treatment's effectiveness, and rigid bronchoscopy was applied for the dilatation of tracheal stenosis.

The role of interventional pulmonology for the postoperative bronchopleural fistula.

Background: : Postoperative bronchopleural fistula (BPF) remains a serious complication due to its high morbidity and mortality. Although various endoscopic techniques have been defined for the closure of BPF previously, no standard algorithm yet exists.

Aims: To study the effectiveness and safety of various endoscopic procedures in an interventional pulmonology unit.

Imaging findings of a rare pararectal splenosis and literature review.

Pararectal splenosis is an extremely rare lesion caused by ectopic auto-transplantation of splenic tissue after splenic trauma or splenectomy. It is often asymptomatic and detected incidentally during radiologic evaluation. We present a 24-year-old male with pararectal splenosis.

Functional characterization of AVPR2 mutants found in Turkish patients with nephrogenic diabetes insipidus.

Diabetes insipidus is a rare disorder characterized by an impairment in water balance because of the inability to concentrate urine. While central diabetes insipidus is caused by mutations in the , the reason for genetically determined nephrogenic diabetes insipidus can be mutations in or After release of AVP from posterior pituitary into blood stream, it binds to AVPR2, which is one of the receptors for AVP and is mainly expressed in principal cells of collecting ducts of kidney. Receptor activation increases cAMP levels in principal cells, resulting in the incorporation of AQP2 into the membrane, finally increasing water reabsorption.
