摘要:

AbstractWe report a case of a right renal arteriovenous malformation with high output cardiac failure and hypertension which was cured by nephrectomy. Hemodynamic findings pre‐and post‐operatively are presented. Plasma renin activity (PRA), both from peripheral venous and renal vein samples, was assessed. The fall in PRA associated with nephrectomy lends support to the suggestion that the renin‐angiotensin system plays a role in the hypertension in these pat

摘要:

AbstractExercise capacity is documented to be poor in patients with end stage renal failure undergoing regular hemodialysis, but there is little information about exercise capacity in patients on continuous ambulatory peritoneal dialysis (CAPD). We studied a group of 18 patients undergoing CAPD, with a variety of cardiorespiratory disorders, using a progressive load treadmill exercise test. The influence of intraperitoneal fluid on work capacity was also assessed. The mean maximum oxygen uptake (VO2max) of the CAPD patients was reduced considerably (14.6 ml kg‐1min‐1) compared with matched control subjects (33.6 ml kg‐1min‐1). This corresponded to the difficulty experienced by these patients in carrying out daily activities. There was no significant change in VO2max or in maximum heart rate with the peritoneal cavity full. We conclude that physical fitness is poor in CAPD patients and that the infusion of dialysis fluid into the peritoneal cavity does not affect physical work capacity

摘要:

AbstractIndices of past lead absorption were measured and compared in patients with chronic renal failure from many causes, including some with chronic lead nephropathy. X‐ray fluorescence (XRF) yielded finger bone lead concentrations by a newin vivomethod. These correlated significantly with excess urinary lead following calcium di‐sodium EDTA (ethylenediamine tetra‐acetate) and erythrocyte lead concentration.Discriminant function analysis demonstrated that the patients in the study could be separated into two groups without any reference to the EDTA lead excretion test using the following variables, all of which contributed significantly to the discrimination. In order of importance, these were: a childhood history of acute lead poisoning, a history of gout, a family history of gout and detectable XRF finger bone lead.Although the XRF finger bone lead measurement is convenient and non‐invasive, its lack of sensitivity (48%) limits its usefulness as a screening test for chronic lead neph

摘要:

AbstractBalloon valvuloplasty was used to treat congenital pulmonary valve stenosis in 13 patients, 11 with isolated pulmonary stenosis, one associated with complex univentricular heart and tricuspid atresia, and one associated with tetralogy of Fallot.A balloon catheter was introduced through the pulmonary valve over a guidewire positioned in the distal pulmonary artery and inflated for 15 seconds on two or three occasions to 3 to 5 atmospheres and rapidly deflated.Marked improvement in pressure gradients was achieved in eight of the 11 patients with isolated pulmonary valve stenosis and symptoms disappeared in the only patient in this group who was symptomatic. The two patients with complex congenital malformations improved clinically. The procedure was without complication and satisfactory results have been maintained from two to twelve months later.The procedure offers effective treatment. We believe that pulmonary balloon valvuloplasty should be the initial treatment for isolated severe and moderate pulmonary valve stenosis.

摘要:

AbstractFourteen of 100 geriatric nursing home patients were shown to have evidence of carotid sinus hypersensitivity. The incidence of syncope and falls was noted in prospective follow‐up over 33 months. Falls were classified as either simple or complicated by laceration or fracture. Patients experienced simple falls at similar rates whether carotid sinus hypersensitivity was present or absent. For patients with carotid sinus hypersensitivity, the risk of a laceration was increased more than twofold, that of fracture more than threefold, and that of syncope tenfold. Carotid sinus hypersensitivity warrants greater attention as a contributory factor to serious falls and syncope in the elderly, and its importance may have been underestimated in the pas

摘要:

AbstractSeven patients demonstrating the difficulties in diagnosis and management of hepatic vein occlusion are presented. The syndrome may present in an acute form with upper abdominal pain, abdominal swelling, ascites and tender hepatomegaly or in a chronic form, mimicking cirrhotic ascites. The clinical features, predisposing factors, liver scan and liver biopsy may all suggest the condition, but hepatic venography is essential for diagnosis and as a preliminary to treatment. It is suggested that early side to side portacaval anastomosis is the current treatment of choice.

摘要:

AbstractThe mortality and morbidity of the 241 survivors of an acute gastrointestinal hemorrhage treated between 1958 and 1964 are reported. The major purpose of this study was to assess the subsequent risk to life and health of patients presenting with acute upper gastrointestinal bleeding. Patients without dyspepsia and with a negative single contrast barium meal study had an excellent prognosis. Life Table analysis showed that the gastric ulcer patients had a mortality not significantly different from that of the Australian population, with the higher risk of death from ulcer balanced by a lower risk of fatal vascular disease. Duodenal ulcer patients had an increased mortality attributable to a 290% increase in deaths from vascular disease, but only one of the 84 died of an ulcer complication. The association between duodenal ulcer and vascular disease has been present for decades. It is unlikely to be associated with hypertension, diabetes mellitus, diet, stress, or smoking and deserves further study.

摘要:

AbstractPrediction of clinical response to induction treatment was studied in a group of 16 children and adolescents with acute myeloid leukemia (AML) by a colony inhibition assay. Samples from ten of 16 patients formed colonies in agar and cells were available from nine of these ten for further study. The system correctly predicted the response of eight of the nine patients (89%) with a confidence level of greater than 80% in all cases and thus produced useful results in half of the series of 16 children. The incorrect prediction occurred in a child whose leukemia had a very low plating efficiency and who relapsed soon after achieving remission. While this methodology requires further development and assessment, it shows great promise in aiding in the selection of appropriate chemotherapy for individual patients with AML.

摘要:

AbstractA calcium loading test performed on seven of eight children with idiopathic hypercalciuria identified the hyperabsorptive form of hypercalciuria in five and renal hypercalciuria in one. The type of hypercalciuria was not identified in the other patient. Three children presented with hematuria without calculus formation. Chlorothiazide reduced the urinary calcium excretion level in two of six patients to the normal range. The addition of cellulose phosphate to chlorothiazide reduced the urinary calcium excretion level to the normal range in those four patients who showed an incomplete response to chlorothiazide alone. There was clinical improvement with cellulose phosphate in another child whose symptoms did not disappear after chlorothiazide had reduced urinary calcium level to the normal range. Cellulose phosphate is effective in children with recurrent stone formation who have shown inadequate response to chlorothiazide.
