Systematic review with meta-analysis: ondansetron for vomiting in children with acute gastroenteritis.

Background: Vomiting in children with acute gastroenteritis is a common symptom, and it is considered to be the main cause of failure of oral rehydration therapy.

Aim: To systematically update evidence on the effects of ondansetron (5-HT3 serotonin antagonist) for vomiting in children with acute gastroenteritis.

Methods: The Cochrane Library, MEDLINE and EMBASE databases were searched up to April 2016, with no language restrictions, for randomised controlled trials (RCTs).

Prevalence and predisposing conditions for atrial fibrillation in hospitalised patients with hypertension.

Background: Hypertension, due to its prevalence, is a common and independent risk factor for atrial fibrillation (AF). High blood pressure causes structural and functional changes in the myocardium, leading to an increased risk of arrhythmia. This risk is higher when hypertension is accompanied by concomitant diseases that contribute to the development of AF.

Morphometrical studies of posterior fontanel in different periods of foetal life.

Purpose: There are 6 fontanels in the newborn's skull. Scientists have been mainly interested in the development of anterior fontanel in foetus and newborn. There are no researches about the development of posterior fontanel.

Development of the human eyeball and orbit during the fetal life.

Purpose: The aim of this paper was to describe the development of the human eyeball and orbit during fetal life.

Material And Methods: Eighteen human fetuses (36 eyes and 36 orbits) with gestational age ranging from 17 to 28 weeks were examined. Fetuses died in the first hours of life due to immaturity and did not reveal any developmental anomalies.

The ossification of the metacarpal and phalangeal bones in human foetuses.

An evaluation was made of the ossification level of the metacarpal and phalangeal bones in human foetuses of both sexes from the 4th to the 9th month of gestation. Our results indicate that ossification of phalangeal bones 1 to 5 always started at the distal end of the phalanx and endochondral ossification prevailed in the proximal phalanx of the thumb.
