[Testicular nodules of infertile men and contrast enhanced ultrasonography: preliminary study].

Introduction: The incidence of testicular nodules discovered during infertility evaluation is increasing. These nodules are suspicious of malignancy. There is no paraclinical examination which allows histological orientation to these nodules.

Influence of motilin on gastric fundus tone and on meal-induced satiety in man: role of cholinergic pathways.

Background: Motilin agonists are strong gastroprokinetics, but their impact on symptoms in delayed gastric emptying has been disappointing. It has been speculated that it is due to the contractile effect of motilin agonists on the proximal stomach, but the pathway involved and the symptomatic consequences have been incompletely elucidated.

Aims: To study whether motilin enhances proximal stomach tone and enhances meal-induced satiety and to evaluate whether this effect involves a cholinergic pathway.

Therapeutic embolization of a thoracoacromial artery perforated by placement of a deep venous catheter.

An 82-year-old man presented with massive external bleeding from the puncture site after placement of a deep venous catheter in the right subclavian vein. Emergent angiography revealed contrast extravasation along the central venous catheter tract due to perforation of the right thoracoacromial artery. Superselective catheterization of the bleeding artery followed by microparticle embolization definitively stopped the hemorrhage.

Radiolucent chest lesions in a neonate due to congenital cystic adenomatoid malformation.

A localized radiolucent cystic lesion in the left lower lobe with shift of the mediastinum to the opposite side in a neonate is shown on chest X-ray and CT. Findings on conventional X-ray and particularly on CT are very suggestive for congenital cystic adenomatoid malformation type 1. Histology after lobectomy confirmed the diagnosis.
