Primary antiphospholipid syndrome presented by total infarction of right kidney with nephrotic syndrome.

We report the case of a young woman with primary antiphospholipid syndrome (APS), which presented with acute renal failure, hypoproteinemia, hypoalbuminemia and nephrotic proteinuria. Investigations showed total infarction of right kidney by extensive arterial and vein thrombosis and presence of anticardiolipin antibodies IgG isotype (anti-beta2-glycoprotein I-positive). She was submitted to right nefrectomy and initiated anticoagulant therapy. After nefrectomy, the postoperative period was marked by the development of arterial hypertension and persistence of nephrotic syndrome. Hypertension was treated with antihypertensive drugs (IECA, beta-blocker and calcium antagonist). As the nephrotic syndrome persisted despite anticoagulant and antihypertensive therapy, the patient was treated with oral corticosteroids. Her renal function improved, hypoproteinemia and hypoalbuminemia corrected to normal values and proteinuria decreased to subnephrotic value. We discuss the unusual presentation of this case of primary antiphospholipid syndrome with total unilateral renal thrombosis and nephrotic syndrome that respond to anticoagulant, antihypertensive and corticosteroid therapy.

[Emphysematous cholecystitis].

Emphysematous cholecystitis (EC) is a rare and dramatic disease that requires prompt therapeutic procedures. The authors report a case of a 70-year-old-woman, admitted to the Intensive Care Unit for Infectious Diseases of the Santa Maria Hospital, with the diagnosis of EC. The literature on EC is also reviewed.

[Febrile coma and disseminated intravascular coagulation following heat stroke].

A clinical case that occurred in a 42 years old female and which fulfils the diagnostic criteria for the entity described as Heat Stroke is presented. In this case, besides the usual manifestations of hyperpyrexia without sweating along with consciousness disorders, features of consumptive coagulopathy, rhabdomyolysis and well marked laboratory liver dysfunction have also been found. The severity of this situation and its less common occurrence in temperate climates, together with the uncertainty in establishing the diagnosis, namely when infection is suspected--in the present case the initial diagnosis was Sepsis, which led to patient's admission in an infectious diseases intensive care unit--motivate the authors to make this report. Furthermore, they consider this case to be a good example of the varied clinical and laboratory manifestations and possible severe complications that Heat Stroke may display.

[Lower intestinal obstruction caused by a lactobezoar].

Two case of the so-called "milk curd obstruction" syndrome are reported. Although seldom found elsewhere than in the stomach, more distal obstruction in the ileum or the transverse colon by milk curd aggregates may mimic more classical causes of obstruction if one is not aware of the possibility of such incident related to feeding. Appropriate interviewing of the mother about regimen and medications will be of great help, in investigating the cause of the abdominal disorder, obviating the need for surgical intervention if confirmed by radiopaque enema.

Second operation for repair of biliary atresia.

In our experience with biliary atresia, there are few cases amenable to reoperation for recurrent jaundice. All authors would agree that specific conditions such as complete bile flow recovery from the first operation followed by early recurrence should be an unquestionable case for revision of the anastomosis, inasmuch as no biologic signs of ongoing cholangitis can be traced. The same decision would apply to the problem of bile leakage after hepatoportocholecystostomy. In other cases, however, one should be aware that these reoperations expose the child to ascitis, poor healing of the abdominal wound, liver failure, and also bring with the decision to reoperate undue hopes to the parents of the child. Moreover, if the child should be a future candidate for liver transplantation, it may be wiser to avoid useless laparotomies and abdominal dissections that are known to complicate the task of hepatectomy.

[Management of uropathies diagnosed prenatally. Discussion based on a series of 53 cases].

From 1982 to 1986, 53 newborns (26 boys and 27 girls) were referred to the authors for the management of a congenital anomaly of the urinary tract, following a prenatal ultrasonographic diagnosis. The postnatal diagnosis was hydronephrosis in 27 children (10/27 bilateral cases), unilateral multicystic dysplasia in 11, ureteral duplication in 6, primary megaureter or orthotopic ureterocele in 5 (1/5 bilateral case) and posterior urethral valves in 4. An early urinary tract infection was noticed in 5 cases only and 2 boys with urethral valves had an altered renal function at birth. Eight children with a mild lesion were not operated. A radical procedure was performed in 15 cases: excision of a multicystic kidney (10 cases) or heminephrectomy of an upper non-functioning pyelon (5 cases: 3 with heterotopic ureterocele and 2 with ectopic ureter). Thirty children were submitted to a corrective procedure: electrocoagulation of urethral valves (4 cases), ureteroneocystostomy (6 cases) or pyeloplasty (19 unilateral and 1 bilateral procedure). Except in a case of pyeloplasty the result of the reconstructive surgery was considered as good or satisfactory from a radiological point of view, with a mean follow-up of 1.5 year. The essential point of discussion is the evaluation of the factors which must be taken in account to plan an early reconstructive surgical treatment. The main factor, I.e. the natural history of these congenital anomalies remains at yet difficult to predict in a great number of cases.(ABSTRACT TRUNCATED AT 250 WORDS)

Banding patterns of the chromosomes of Cebus albifrons. Comparative study with Cebur apella.

Quinacrine- and Giemsa-banding studies of the chromosomes of Cebus albifrons permitted to obtain a pattern that characterizes the species. The topography of the bands has been compared with that of Cebus apella. Each chromosome pair of C. albifrons has a homologue in C. apella. The differences between the two karyotypes are the result of five pericentric inversions.

The relationship of education to critical thinking ability and values among nurses: socialization into professional nursing.

Exposure to faculty is assumed to positively influence critical thinking ability and professional values; therefore, faculty must be assumed to be superior in these characteristics. As a first step toward testing these assumptions, this study used a cross-sectional survey technique to compare critical thinking ability and values in ADN-prepared (n = 32) and BSN-prepared (n = 32) registered nurses, nursing faculty (n = 32), and sophomore college students (n = 32) beginning a baccalaureate degree program in nursing. The critical thinking ability of faculty was not significantly higher than that of sophomore nursing students when the influence of age was controlled statistically. The values of all three groups of nurses were strikingly similar, although faculty valued achievement most highly (P = .0001), while sophomore students valued goal orientation most highly (P = .001). All subjects valued support highly, but only sophomore students valued benevolence highly.
