In this study, we present the first experimental results for stable barium (Ba) isotope ((137)Ba/(134)Ba) fractionation during low-temperature formation of the anhydrous double carbonate BaMn[CO(3)](2). This investigation is part of an ongoing work on Ba fractionation in the natural barium cycle. Precipitation at a temperature of 21±1°C leads to an enrichment of the lighter Ba isotope described...

The barium esophagram is a valuable diagnostic test for evaluating structural and functional abnormalities of the esophagus. The study is usually performed as a multiphasic examination that includes upright double-contrast views with a high-density barium suspension, prone single-contrast views with a low-density barium suspension, and, not infrequently, mucosal-relief views with either density...

RATIONALE Even though barium sulphate aspiration during upper gastrointestinal examination is a well-known phenomenon, complication such as long-term lung injury and death may still occur. This may depend upon the concentration, amount, anatomy, or certain predisposing factors. PATIENT CONCERNS A 47-year-old woman who had a barium swallow to screen for foreign body in esophagus. DIAGNOSES C...

The microvasculature was investigated in the normal bowel and in ulcerative colitis and Crohn's disease. Tissue samples from postoperative colectomy specimens in which the microvasculature had been perfused with barium sulphate suspension were examined. Microradiography was used to study intramural vascular pattern which was abnormal in both disease states. A recently described radiograph fluor...

Alqurashi MM, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-220486 Description A healthy 43-year-old gravida 14, para 12+1 woman, developed Sheehan syndrome followed by disseminated intravascular coagulopathy and sepsis post-Caesarean section. Her postoperative course was further complicated by a hospital-acquired pneumonia for which she required endotracheal intubation and mechanical ventilat...

the hyperpolarization of cones. This proposal together with the suggestion that barium ions reduce the potassium efflux in cones predicts that the receptor potential amplitude of cones should decline in the presence of barium. Such a decrease is noted in this study and elsewhere. Also consistent with this interpretation is our present finding that barium ions delay the onset of rapid dark adapt...

PURPOSE The use of barium enemas to confirm the anastomotic integrity prior to ileostomy closure is still controversial. The purpose of the study was to determine the utility of routine contrast enema prior to ileostomy closure and its impact on patient management in patients with a low pelvic anastomosis. METHODS One hundred forty-five patients had a temporary loop ileostomy constructed to p...

This study measured dose-response of a range of commercially available liquid barium materials designed for use in videofluoroscopic oropharyngeal swallowing assessments, particularly as they relate to the necessity of adding a thickening agent for swallow safety. A group of 25 adult males representing various medical diagnoses consented to participate, with 16 qualifying to complete a videoflu...

The aim of this study was to evaluate the necessity of urgent barium enema in suspected cases of acute malignant colonic obstruction. We reviewed the medical records and images for 20 patients with suspected acute colonic obstruction. Nine patients were excluded. Computed tomography (CT) and urgent barium enema images for the remaining 11 cases were reviewed and the results were compared with t...
