introduction: proximal displacement of stomach and gastro-esophageal junction into the thoracic cavity results in a condition known as hiatal hernia (hh). sometimes this entity is neglected in practice and the patient is handled as gastroesophageal reflux disease, asthma or other non-surgical diagnosis.case: here we present a 6 months-old female infant who present with bloody emesis since two m...

Barium studies investigations (barium swallow, barium meal and barium enema) are the basic routine radiological examination, where barium sulphate suspension is introduced to enhance image contrast of gastrointestinal tracts. The aim of this study was to quantify the patients' radiation doses during barium studies and to estimate the organ equivalent dose and effective dose with those procedure...

The barium is often used in radiocontrast examinations of the digestive system because of mucosal absorption is limited. Massive barium aspiration is a rare complication, especially when there is no anatomic or neurological defi cit. The depending on barium concentration can cause various lung effects. When the literature is reviewed, barium aspiration may be asymptomatic or lethal in massive a...

OBJECTIVES/HYPOTHESIS This study tested the hypotheses that swallowing apnea duration (SAD) will increase given barium versus water, chemesthetic stimuli (i.e., water < ethanol, acid, and carbonation) mixed with barium, age (older > younger), and genetic taste differences (supertasters > nontasters). STUDY DESIGN Prospective group design. SETTING University Medical Center. METHODS Eighty ...

The International Programme on Chemical Safety (IPCS), established in 1980, is a joint venture of the United Nations Environment Programme (UNEP), the International Labour Organization (ILO), and the World Health Organization (WHO). The overall objectives of the IPCS are to establish the scientific basis for assessment of the risk to human health and the environment from exposure to chemicals, ...
