摘要:

A case of gas-producingSalmonella typhimuriuminfection of the soft tissue of the leg is reported in a patient with predisposing factors which include systemic lupus erythematosus, corticosteroid therapy, hepatic disease, and hemolysis. Aerobic bacterial infections associated with clinically significant gas production are reviewed.Escherichia coliandKlebsiella-Enterobacterspecies are the organisms most frequently isolated, and diabetes mellitus is the most common underlying disease.

摘要:

A single protocol using both Conn's and Biglieri's criteria was adopted in an attempt to reach a diagnosis of primary aldosteronism in 48 normokalemic “essential” hypertensives. Two distinct groups of patients were found by Conn's criteria Group 1, consisting of five patients (10 per cent) had an elevated aldosterone excretion on high salt diet without suppressed renin, and Group II, consisting of six patients (12 per cent) had a low renin response on a low salt diet and upright posture; their individual aldosterone excretion on a high salt diet was normal. Several explanations for the occurrence of these two abnormalities are set forth. Biglieri's criteria for the diagnosis of primary aldosteronism were observed in six patients. However, their aldosterone excretion was stimulated by salt depletion, obviating the possibility of autonomous aldosterone-producing adenoma. Based on the clinical criteria designed by both Conn and Biglieri, it is concluded that primary aldosteronism was not the cause of hypertension in 48 normokalemic “essential” hypertensives.

摘要:

Reports indicate that patients do not follow medical instructions faithfully and that physicians are unable to judge their individual patient's cooperation levels. This paper evaluates criteria available to the physician for making such judgments. The data were obtained from a series of patients followed for two years after an acute attack of peptic ulcer. Objective measures of antacid and atropine intakes were made. Patients' regularity of attendance at clinic did not provide an index to their intake of antacid. Requests for prescriptions of atropine showed no relationship to intake of atropine as measured by urine tests. A count of the number of atropine tablets the patient actually obtained from the hospital pharmacy provided at best a moderately accurate index to intake.

摘要:

A renal functional abnormality associated with a failing liver has been observed for many years. Extensive study over the last decade has demonstrated a decreased glomerular filtration rate, an avid tubular reabsorption of sodium, and a decreased renal blood flow associated with an increase in renal vascular resistance. Current evidence suggests a functional disturbance of the kidney perhaps secondary to a circulating substance released by, or not detoxified by, the failing liver. Intrarenal shunting may be the renal mechanism producing the clinical syndrome. No effective therapy has been developed to date. A fatal outcome is to be expected.

摘要:

In vitrocomparisons of inhibitory activity of ampicillin, cephalothin, gentamicin, ampicillin/gentamicin, and cephalothin/gentamicin combinations were made with 273 Enterobacteriacae. Fifty-two per cent of the entire group were inhibited by 0.7 µg gentamicin and 6 µg ampicillin per ml, and 56 per cent were inhibited by gentamicin (0.7 µg/ml) plus cephalothin (6 µg/ml), demonstrating a distinct bacterial advantage of the combinations over either drug used alone. Synergism was observed for 33 per cent of the strains with ampicillin/gentamicin and for 51 per cent with cephalothin/gentamicin; the superiority of the latter combination was due to its action onKlebsiellastrains The use of ampicillin/gentamicin and cephalothin/gentamicin for the treatment of severe Gram-negative infection in patients with serious underlying disease resulted in a failure rate of 33 and 42 per cent, respectively. Infections caused by microorganisms for which the combinations were synergisticin vitrohad a significantly better outcome than infections caused by microorganisms for which no synergism had been found.

摘要:

The influence of ventricular tachycardia on phasic aortic flow velocity using a Doppler flowmeter catheter system was studied in 27 patients: 18 during transient episodes of ventricular tachycardia, and 13 during pacemaker-induced ventricular tachycardiaIn the group with transient episodes of ventricular tachycardia, decreased and marked irregularity of phasic peak aortic flow velocity was observed uniformly and these findings were much more pronounced at rapid ventricular rates “Alternans” in peak aortic flow velocity was observed in one patient with a ventricular rate of 150/minute. Short episodes of ventricular fibrillation occurred subsequently after ventricular tachycardia in one patient Peak aortic flow velocity decreased markedly during this episode.In the group of pacemaker-induced ventricular tachycardia, the peak phasic aortic flow velocity decreased proportionally and progressively with increase of ventricular pacing rates; marked irregularity of the peak phasic aortic flow velocity was observed during ventricular pacing at a rate above 160/minute
