[A woman with acute abdominal pain in the night].

A 43-year-old woman came to the Emergency Room with acute abdominal pain during the night. CT examination of the abdomen showed ventral herniation of the stomach and parts of the small intestine and colon in the right hemithorax. We made the diagnosis 'symptomatic Morgagni hernia', a rare congenital defect that is usually diagnosed soon after birth.

SCN5A mutations in Brugada syndrome are associated with increased cardiac dimensions and reduced contractility.

Background: The cardiac sodium channel (Na(v)1.5) controls cardiac excitability. Accordingly, SCN5A mutations that result in loss-of-function of Na(v)1.

[A young woman with acute abdominal pain].

A 21-year-old woman reported to the first aid with acute pain in the right lower abdomen since 5 days, diarrhoea and nausea. There was no fever or muscular guarding, and no signs of inflammation in the blood screening. An ultrasound and a CT-scan of the abdomen showed an ovoid, fatty mass compatible with an appendagitis epiploica.

Computer-aided detection of lung cancer on chest radiographs: effect on observer performance.

Purpose: To assess how computer-aided detection (CAD) affects reader performance in detecting early lung cancer on chest radiographs.

Materials And Methods: In this ethics committee-approved study, 46 individuals with 49 computed tomographically (CT)-detected and histologically proved lung cancers and 65 patients without nodules at CT were retrospectively included. All subjects participated in a lung cancer screening trial.

Structural degeneration of pulmonary homografts used as aortic valve substitute underlines early graft failure.

Objectives: The limited availability of donor valves and experimental evidence that pulmonary valves can withstand systemic pressure made us use cryopreserved pulmonary homografts as aortic valve substitutes. We observed a high incidence of early reoperation because of severe graft insufficiency due to cuspal tears. The mid-term results are evaluated in this study and histological analysis of explanted homografts is performed to investigate the cause of graft failure.
