Liver abscess and pseudotumoral gastric lesion caused by chicken bone perforation: laparoscopic management.

The accidental ingestion of a foreign body into the gastrointestinal tract is not uncommon, but the vast majority of foreign bodies pass through the gastrointestinal tract uneventfully within a week. Less than 1% of patients with foreign body ingestion develop complications such as perforation of the gastrointestinal tract. The migration of an ingested foreign body may result in chronic inflammation, a silent clinical course, and radiological features suggestive of a neoplasm.

Childhood obesity treatment: double blinded trial on dietary fibres (glucomannan) versus placebo.

Dietary fibres are frequently used for the treatment of paediatric obesity. The aim of this clinical trial is to evaluate the efficacy of glucomannan in the child obesity management. This experimental design was double blinded with a block randomisation, alpha = 0.

[Pharmacologic effects and safety profile of bethanechol in the differential diagnosis of pseudo-anginal thoracic pain].

The use of bethanecol has recently been proposed to improve the diagnostic accuracy of esophageal manometry in identifying the origin of symptoms in patients with non cardiac chest pain. In this study we report our experience in 30 patients who underwent esophageal functional studies. Despite its low diagnostic value, bethanecol test (two subsequential doses of 50 micrograms/kg) demonstrated an excellent safety profile, there were few side effects, and patients tolerance was good.

Gas exchange during exercise in obese children.

Twenty-three obese children, aged 9 to 14 years, ranging in percentage overweight from 26% to 83% (median 51.6% +/- 16.3%), and 37 normal-weight children, matched for sex, age and height, performed a maximal exercise test on a treadmill.
