11-Oxygenated androgens are not secreted by the human ovary: in-vivo data from four different cases of hyperandrogenism.

Objective: Differentiation of an adrenal from an ovarian source of hyperandrogenemia can be challenging. Recent studies have highlighted the importance of 11-oxygenated C19 steroids to the androgen pool in humans. The aim of this study was to confirm the origin of 11-oxygenated androgens in females and to explore their potential use in the diagnostics of hyperandrogenic disorders.

[Radiation exposure of the eye lens in orthopedics and trauma surgery : A pilot study].

Background: On 27 June 2017 the Act on new regulation of the law for the protection against the harmful effects of ionizing radiation was passed. One of the main innovations in daily surgical practice in the now legally stipulated provisions is the lowering of the eye lens dose to 20 mSv/year (§§ 78, 212 Radiation Protection Act, StrlSchG).

Material And Methods: To estimate the level of exposure of the eye lens to ionizing radiation that is to be expected in the course of surgical interventions, the dose that surgeons receive during surgery was determined.

Radiological evidence of purulent infections in ancient Egyptian child mummies.

Objective: To identify computed tomography (CT) findings of purulent infections in ancient Egyptian child mummies.

Materials: Whole-body CT examination of 21 ancient Egyptian child mummies from German (n = 18), Italian (n = 1), and Swiss museums (n = 2).

Methods: CT examinations were evaluated for estimation of age at death and sex of the children.

Corona again? SSC after a severe COVID-disease.

Secondary sclerosing cholangitis (SSC) is a severe complication of intensive care treatment in critically ill patients. It is characterized by rapid onset and severe chlolestasis with elevation of gGT. In contrast to primary sclerosing cholangitis, SSC-CIP has a distinct and timely well defined trigger and can have a rapid progress to cirrhosis and liver failure.

Embolic Protection in Complex Femoropopliteal Interventions: Safety, Efficacy and Predictors of Filter Macroembolization.

Objectives: To evaluate the safety and efficacy of a filter embolic protection device (FEPD) in endovascular interventions of the femoropopliteal arteries.

Methods: Patients who underwent endovascular interventions of the femoropopliteal arteries between 2008 and 2016 and in whom the SpiderFX FEPD was applied were included in this retrospective study. Clinical and angiographic characteristics, filter macroembolization (FME), device-related complications, distal embolization, as well as the early clinical and hemodynamic outcome, were assessed.
