Streptococcus mitis is a bacterium traditionally regarded as a normal commensal of the oropharynx, skin, and intestinal and genital tracts. To our knowledge, we describe the first case of bilateral lung abscesses caused by S. mitis in an immunocompetent host. The abscesses were successfully treated with clindamycin and gentamicin. Our case illustrates that(More)
Three isolates of a Gram-negative, catalase- and oxidase-positive, rod-shaped bacterium, isolated from the lung and liver of two beaked whales, were characterized by phenotypic and molecular genetic methods. Based on cellular morphology and biochemical criteria, the isolates were tentatively assigned to the family Flavobacteriaceae, although they did not(More)
Calcium metabolism was studied in 47 patients with borderline or lepromatous leprosy. Total and ionized calcium, phosphorus, creatinine, total alkaline phosphatase, parathyroid hormone (PTH), 25-hydroxy vitamin D [25(OH)D], and 1,25-dihydroxy vitamin D [1,25(OH)2D] were measured in serum; calcium and total hydroxyproline were determined in urine. Total(More)
OBJECTIVE To analyse the number of attendances and the direct cost of pharmaceutical prescription arising from a year-long monitoring of hypertense patients. SETTING Health Centre. DESIGN A prospective observation study. PATIENTS 220 hypertense patients, undergoing arterial pressure (AP) monitoring, were chosen by means of systematic random sampling.(More)
Exchangeable 22Na (ExNa), total body water (TBW) and the inulin space (InSp) were determined in two-kidney, two-clip (2K-2C) hypertensive and sham operated (normotensive) control rats 6-8 weeks after surgery. TBW (ml/kg lean body weight) was the same in hypertensive and sham rats. In contrast, ExNa (mEq/kglbw) and InSp (ml/kglbw) significantly increased (p(More)
A 73-year-old man presented with dyspnea, right-sided pleural effusion, and bilateral pulmonary infiltrates. The pleural fluid revealed adenocarcinoma cells that stained positively for prostatic specific antigen (PSA), which confirmed this uncommon metastatic involvement from prostate cancer. The dyspnea, effusion, and infiltrates disappeared after therapy(More)
A 69-year-old woman with a history of diabetes and hypertension, was referred to the Hospital of Laredo because of hyponatraemia. She had weakness and slight dyspnoea with no evidence of extracellular fluid volume depletion or oedema. Serum sodium level on admission was 125 mol l-1, plasma osmolality 270 mosmol kg-1, simultaneous urine osmolality was 580(More)
