Diurnal rhythm of urinary calcium excretion in adults.

Twenty-four-hour urinary calcium excretion is normally the equivalent of daily calcium intake, and varies between 200-300 mg/dL with a calcium/creatinine ratio of 0.07-0.15.

A brucellosis case with ascites, hearing loss and pancytopenia.

To date there has been no association of ascites, hearing loss and pancytopenia in brucellosis in the literature. A 25-year-old female patient was hospitalized with fever, hearing loss, ascites and pancytopenia. Cultures from bone marrow and ascites yielded growth of Brucella melitensis and Brucella standard tube agglutination was found to be positive at a titer of 1/1280.
