A 79-year old female patient with antecedents of headache and fever, was admitted because of fatigue, anorexia, anemia and elevated ESR. After admission she presented with rheumatic polymyalgia and synovial effusion in the knee. A first biopsy of the temporal artery was normal. After dismissing other possible causes a second biopsy of the contralateral temporal artery was bone and confirmed giant cell arteritis. Diagnostic value of a second temporal artery biopsy is discussed and justified by: a) a confirmed diagnosis is necessary for prolonged treatment with corticosteroids, b) if it is decided to treat the rheumatic polymyalgia with lower doses of corticosteroids than for temporal arteritis the certainty that no temporal arteritis is present and c) shortening the hospital stay and lowering the cost and number of diagnostic procedures. The frequency of arthritis and synovial effusion in temporal arteritis are also discussed.

During a period of 29 months positive hemocultures to Streptococcus agalactiae corresponding to eight adult patients have been observed. These bacteria were apparently responsible for the clinical picture in five patients. In other two patients S. agalactiae appeared in the course of a sepsis caused by other germ. The remaining patient had a transient bacteremia and no treatment was required. Septic shock and bacterial endocarditis were the cause of death in two patients. Six patients cured. Literature on this subject is reviewed and the better prognosis of sepsis due to S. agalactiae in adults than in neonates is stressed. Endocarditis and meningitis occur as severe complications with poor prognosis. In patients with endocarditis the administration of penicillin and gentamicin as well as the consideration of early surgical replacement of the affected heart valve is recommended. Intravenous penicillin and gentamicin associated with intrathecal gentamicin are indicated in meningeal infections. Vancomycin is a good substitutive antibiotic in patients with penicillin hypersensibility.

A 75 year-old male presented with hyperkalemia unexplained by a moderate renal insufficiency, low basal levels of aldosterone and renin with a subnormal response to walking and saline depletion, and normal glucocorticoid function. The hyperkalemia was corrected by fluorocortisone administration. The concept of hypoaldosteronism is reviewed, defining it as an isolated aldosterone deficiency and thus excluding the combined deficiency of cortisol and aldosterone and the suprarenal enzyme deficits that simultaneously involve mineralocorticoid and glucocorticoid synthesis. Depending on the presence or absence of alterations of the renin-angiotensin axis, this infrequent syndrome can be pathophysiologically classified as low, normal or high renin hypoaldosteronism. The characteristic features of each type are described, and emphasis is made on the need for a high index of suspicion when unexplained hyperkalemia is present in order to perform the appropriate tests to confirm or rule out hypoaldosteronism.

Human foetal small intestine was shown to contain both alpha- and beta-adrenoceptors with a predominance of beta-adrenoceptors. The tissue examined was obtained from foetuses of gestational age between 8 and 26 weeks.
