To evaluate the usefulness of the Forrest classification and the complete Rockall score with customary cut-off values for assessing the risk of adverse events in patients with upper gastrointestinal bleeding (UGI-B) subject to after-hours emergency oesophago-gastro-duodenoscopy (E-EGD) within six hours after admission. ⋯ In patients with UGI-B subject to after-hours endoscopy, a 'high-risk' Rockall score permits an estimation of the risk of death within 30 days but not of re-bleeding. A 'high-risk' Forrest score is not significantly associated with the study endpoints.

Nontyphoidal Salmonella infections often present with self-limited gastroenteritis. Extraintestinal focal infections are uncommon but have high mortality and morbidity. Urinary tract infection caused by nontyphoidal Salmonella is usually associated with structural abnormalities of the urinary tract. ⋯ Salmonella Group D was isolated from his urine specimen. Salmonella should be considered as a possible causality organism in patients with primary hyperparathyroidism and nephrocalcinosis who develop urinary tract infection. These patients need to be aware of the potential risks associated with salmonellosis.

Some kidney diseases are usually associated with changes in kidney size. ⋯ Sonographic determination of pathologic changes in the size of the kidneys necessitates knowing the normal ranges of its lengths especially with respect to height in school-age children.

Whipple's disease is a rare multi-organ infectious disease caused by Tropheryma whipplei. It is fatal without treatment. We report on a 40-year old Afro-Jamaican man who presented with a six-month history of weight loss and diarrhoea. ⋯ Electron microscopy was confirmatory and polymerase chain reaction testing conclusively identified the organisms as T whipplei. Antibiotic treatment resulted in resolution of symptoms. Although the diagnosis of Whipple's disease is difficult, increased awareness should lead to an increase in reported cases with the improvements in diagnostic capabilities.

Recent nutritional profiles of dietary intake have indicated a shift from the ancient diet to the Western diet. The ancient diet provided a high potassium and low sodium intake, which in turn leads to sodium conservation and potassium excretion. This change in the dietary intake is expected to affect potassium and sodium handling in the kidneys. Numerous studies have been done to emphasize the importance of sodium handling by the kidneys and its impact on cardiovascular health. This study will investigate potassium intake and handling, and its impact on the cardiovascular health of a sample of normotensive Afro-Caribbeans by the possible modulation of the renin angiotensin aldosterone system (RAAS). ⋯ The Afro-Caribbean sample has an inadequate daily potassium intake based on the observed intake and recommended values, with a high urinary excretion of the electrolyte compared to other values in the literature. This high potassium excretion could have been partly due to low plasma renin activity levels in the study participants. As a possible consequence, an increase in the nocturnal peripheral resistance is a likely cause for the diminished systolic dip. The lack of correlations between dietary potassium excretion and the blood pressure parameters does not allow any firm inference of the electrolyte's handling and its impact on cardiovascular health in the normotensive Afro-Caribbean participants. However, further research is needed to get a more accurate daily potassium intake value, and a more statistically robust sample to assess whether potassium handling and blood pressure would be affected by a change in potassium intake.
