Using the critical incident survey to assess hospital service quality.

This survey was designed to determine "standards of excellence" in hospital services as defined by (a) former patients, (b) physicians, (c) hospital employees, and (d) corporate insurance subscribers. One hundred forty-seven (147) patients, 188 employees, and 20 corporate subscribers were interviewed by telephone, and 52 physicians were interviewed in their offices. The interview consisted of a single question: "Can you think of a time when, as a patient/employee/employer/physician, you had a particularly satisfying or dissatisfying experience with a local hospital?" Reported incidents were reviewed, and 239 "critical incidents" were identified. These incidents were classified into 12 descriptive categories relating to the underlying factors in the incident reports. Six focus groups were later held with participants segregated by the population pool they represented. These groups were asked to develop definitions of "excellence" in hospital service quality and standards for service which would "exceed expectations." The focus groups created 122 standards of excellence, which were classified into 43 categories. Overall, the largest percentages of corporate, physician, and employee critical incidents were classified as "Administrative Policy" issues. Patients most often reported "Nurturing" incidents as critical to their perceptions of hospital service quality.

T cell subsets in idiopathic glomerulonephritis.

Determination of T lymphocyte subsets using monoclonal antibodies revealed a deficiency of suppressor cells and an elevated helper:suppressor T cell ratio in 7 patients with untreated idiopathic immune complex glomerulonephritis and nephrotic syndrome. Possible pathogenetic mechanisms of immunoregulatory cell imbalance and their implications specifically in reference to idiopathic glomerulonephritis are discussed.

Juxtaglomerular cell tumor.

A 15-year-old female with primary reninism presented with benign hypertension, normokalemia, normal aortagram and normal intravenous pyelogram. The diagnosis was suggested only by a remarkably elevated plasma renin activity (PRA). Selective catheterization of renal vein branches was necessary to make the diagnosis of a tumor. A local resection of the tumor resulted in normalization of blood pressure and PRA. Prior to the definitive surgery, oral propranolol was effective in lowering PRA and blood pressure.

Segmental intrarenal catheterization in renin-mediated hypertension.

Segmental renal vein blood was collected in 9 hypertensive patients who had a focal renal lesion on excretory urography and/or a high peripheral plasma renin activity. The main renal vein catheterization was normal in all patients. Segmental renal vein catheterization demonstrated a renin-producing lesion in 3 patients, all of whom were cured of the hypertension postoperatively. Segmental renal vein catheterization is safe and allows the recognition of increased renin production from focal lesions of the kidney that may not be demonstrated radiographically or by main vein catheterization.

Structure of a juxtaglomerular cell tumor: the presence of a neural component: a light and electron microscopic study.

A 15-year-old girl with hypertension, markedly elevated plasma renin activity, and normal aortogram had a well encapsulated tumor nodule removed from the right kidney. Following surgery, the plasma renin activity and blood pressure became normal and have remained so for the past 12 months. The tumor consisted of juxtaglomerular cells filling the interstitium between endothelium-lined vascular spaces. Electron microscopy disclosed the presence in the interior of the tumor, of unmyelinated nerve bundles with varicosities containing the small, densely cored vesicles characteristic of adrenergic nerves. Nerve terminals were in contact with the juxtaglomerular tumor cells. No basement membrane material was interposed between the nerve endings and the tumor cell; the width of the gap between the two plasma membranes was approximately 150 A. The presence of sympathetic fibers in the juxtaglomerular cell tumor underscores the close biologic relationship between the sympathetic and renin systems.

Double-blind comparison of minoxidil and hydrallazine in severe hypertension.

1. Thirty moderately severely hypertensive patients were studied in a double-blind comparison of minoxidil and hydrallazine in combination with frusemide and propranolol. 2. Blood pressure control in both groups of patients was satisfactory but long-term control appeared to be better in the minoxidil group. 3. Renal function was well preserved in both groups. Evidence of cardiac hypertrophy was slow to resolve despite good control of blood pressure. Side effects were negligible, and patient acceptance and rehabilitation was excellent.

A review of thirty cases of rhabdomyolysis-associated acute renal failure among phencyclidine users.

Fifteen cases of rhabdomyolysis-associated acute renal failure among phencyclidine (PCP) users were seen at our institution between 1979-1984. An additional 15 cases were found from the literature. These 30 cases are reviewed here with respect to the incidence of acute renal failure among PCP users, its possible pathogenesis, clinical and biochemical features, and treatment.
