Alterations of the gallbladder wall is a well known sonographic sign of acute cholecystitis. But thickening of the gallbladder wall is also found in patients without intrinsic gallbladder disease. We present our experience on this regard in patients with cirrhosis, acute viral hepatitis, infectious mononucleosis, halothane hepatitis, fulminant hepatic failure, malaria due to plasmodium falciparum, heart failure, severe malnutrition due to gastric obstruction, septicemia, pyogenic hepatic abscess, amoebic hepatic abscess and in a 14 years old patient with fracture of the skull-acute anemia-shock. Most of these diseases affected the liver directly or indirectly. Knowledge of these alterations of the gallbladder wall in these circumstances are important in order to avoid a the erroneous diagnosis of acute cholecystitis.

The results of intensive therapy and temporary organ substitution by hemoperfusion through a suspension of active hepatocytes in 126 patients suffering from acute hepatic insufficiency (AHI) induced by virus B hepatitis, virus non-A, non-B hepatitis, acute toxic hepatitis, active liver cirrhosis, sepsis leptospirosis long-term subhepatic jaundice are presented in this paper. Hepatic encephalopathia confirmed both clinically and electroencephalographically was registered in all the patients. The patients were subdivided into two groups: a complex of commonly used curative measures according to the intensive therapy for AHI was applied in Group A (67 patients); in Group B (59 patients), alongside with the above measures, temporary organ substitution by hemoperfusion through a suspension of active porky hepatocytes was also performed. The lethality in Group A made up 59% and that in Group B was 37%.

Changes of high molecular weight kininogen (HMW-K) clotting activity, antigen and cleavage in the plasma in the health and various diseases were studied. In 20 healthy individuals clotting activity of HMW-K, as measured by APTT one stage method, was 99 +/- 12% (male) and 84 +/- 15% (female). Antigen as measured by Laurell method were 106 +/- 24% (male) and 91 +/- 21% (female). In 35 patients with disseminated intravascular coagulation (DIC), both activity (78 +/- 33%) and antigen (69 +/- 31%) were statistically lower than those in normal individuals (p less than 0.01). In DIC both activity and antigen of HMW-K was correlated with serum albumin level. These results suggest that the cause of the lower level of HMW-K in DIC especially with septicemia is the result of lower production rather than consumption. In vivo cleavage of HMW-K was detected in plasma of a patient with septicemia and DIC by immunoblotting. The change of HMW-K was also assessed in other pathological states including liver cirrhosis, collagen disease, cardiopulmonary bypass and pregnant women.

Of 72 patients who underwent jejunoileal bypass because of morbid obesity, 69 could be evaluated with special reference to long-term (median 11 years) results. One of the other three had fatal anastomotic leakage, one underwent resection and reversal of shunt because of postoperative gangrene in the bypassed segment, and one died of sepsis and liver failure following cholecystectomy 6 months after bypass. The median body mass index (kg/m2) fell from 45.4 preoperatively to 33.2 after 16 years. Shunt-related complications in early and late follow-up were diarrhoea (n = 15), anal/perianal disorders (15), arthralgia (15), urinary calculi (16), cholelithiasis (5), severe flatulence (7), liver cirrhosis (5), intestinal tuberculosis (1), ileitis (1), severe electrolyte disturbance (4), hypomagnesaemia (22), hypokalaemia (8), and deficiency of vitamin B12 (24), iron (24) and folate (17). Although jejunal bypass effectively reduces weight, the patients are at continuous risk of many complications. However, the improvement in quality of life should not be underestimated.

Hypercalcemic crisis represents a medical emergency. If conservative treatment is ineffective, low calcium bath or zero calcium bath hemodialysis are good alternatives. We report 4 patients treated with calcium free acetate hemodialysis because of hypercalcemic crisis due to breast cancer, hepatocellular carcinoma, cirrhosis of the liver and immobilisation with hydrochlorothiazids' medication. Following 3 h of hemodialysis, serum calcium concentrations fell from a mean value of 3.96 (range 3.53-4.46) mmol/l to 2.71 (2.28-3.12) mmol/l. In 2 patients rapid clinical improvement was achieved and in one oliguric patient diuresis started spontaneously during hemodialysis. One patient died from gram-negative sepsis. In 3 cases the subsequent conservative treatment was sufficient to maintain serum calcium levels within the normal range. Together with the previously reported cases (5 patients treated by hemodialysis with low dialysate calcium and 3 patients by hemodialysis with calcium free dialysate) our experience indicates that hemodialysis is an effective and safe therapy for hypercalcemic crisis.

The authors report a case of Pasteurella multocida meningoencephalitis in a 5 week-old female infant, with special attention to clinical, laboratory and evolutive features. A moderate neurological sequel was observed at follow-up examinations. A brief review of the importance of P. multocida in human pathology is presented on the basis of the international literature, since the authors did not find any Brazilian reports. The most important feature on P. multocida is the prevalence of bacterial meningitis at the extremes of age. Otherwise, significant mistaken was found between Gram stained smears of body fluids for P. multocida and Haemophilus influenzae or Neisseria meningitidis. Because its role in infections following animal bite or scratch and its opportunistic feature, P. multocida must be included among the possible etiologic agent of bacteremia or sepsis in patients with liver cirrhosis or immunosuppression.

Renal vein thrombosis in early infancy is a complication of dehydration and prolonged hypotension. The onset is usually acute and the most common clinical signs are uni- or bilateral frank masses, hematuria, proteinuria and thrombocytopenia. In most cases, with conservative management, the late outcome is favorable. In the adult, renal vein thrombosis is often a silent complication of the nephrotic syndrome, the hypercoagulability of which may be an important factor in the pathogenesis of the thrombosis. Clinically, the presentation of a sudden complete occlusion is that of severe abdominal and lumbar pain with hematuria and loss of function of the kidney that suffers hemorrhagic infarction. Physical examination often reveals an enlarged kidney. With gradual occlusion, renal function is preserved. The initial diagnostic approach is with ultrasound studies and computed tomography; definitive diagnosis is established by renal venography or by selective renal arteriography. In general, a conservative approach including the use of anticoagulant treatment is preferred to surgical intervention. Priapism is a persistent painful penile erection due to ischemic or non-ischemic causes; therapeutic intracavernosal injection of papaverine is becoming the most common cause. In early and mild stages, aspiration of blood from the corpora cavernosa supplemented with intracavernosal irrigation with alpha-stimulating agents is the procedure of first choice; in late and severe ischemia, a shunt procedure may become necessary. Hepatic vein thrombosis occurs in association with a number of conditions considered predisposing factors including the use of oral contraceptives. The clinical picture may be that of an acute illness with abdominal pain, hepatomegaly, ascites and hepatic failure as well as early death. More often, the onset is insidious with slowly developing ascites and wasting. For the diagnosis, hepatic scintigraphy may be helpful but, at present, ultrasonography, computed tomography and magnetic resonance scanning are procedures of choice. There is, as yet, no adequate treatment. A fatal outcome may be prevented by surgical decompression of the congested liver and, in recent years, liver transplantation has been employed. Portal vein thrombosis, in children, is usually considered a complication of umbilical sepsis or a result of a congenital abnormality of the portal vein. In adults, the most frequent causes are hepatic cirrhosis and neoplasia. Clinically, there may be a sudden appearance of ascites with resolution in a symptom-free interval until the onset of other features of portal hypertension occur. Currently, ultrasound real-time imaging supplemented with Doppler capability, computed tomography and magnetic resonance scanning provide the necessary diagnostic information. Variceal hemorrhage is often the first major complication requiring treatment.(ABSTRACT TRUNCATED AT 400 WORDS)

Hepatic transplantation is the only therapeutic choice for end-stage pediatric liver diseases. The survival improvement, registered in the last few years is mainly due to the employment of cyclosporine in therapy, but also to new and sophisticated surgical techniques and immunosuppressive drugs. The indications in children are: biliary atresia after unsuccessful Kasai procedure, paucity of intrahepatic bile ducts (of syndromic and not syndromic type), some metabolic diseases (alfa1 antitrypsine deficiency, hereditary tyrosinemia), post infective cirrhosis, acute fulminant hepatic failure, hepatic malignancies. Absolute contraindications include severe systemic illness, severe cardiac or kidney failure, thrombosis or abnormalities of caval and portal veins, systemic sepsis, HIV infection. Other drawbacks are mental deficiency and the inability of family to care for the child and follow therapy after discharge. Relative contraindications are: HBsAg positivity, HIV positivity without infection, malnutrition. Finally the scarcity of donors of liver of adequate size is an important limitation for transplant especially in childhood.

Sodium and water retention is characteristic of edematous disorders including cardiac failure, cirrhosis, nephrotic syndrome and pregnancy. In recent years the use of a sensitive radioimmunoassay for plasma vasopressin has implicated the role of nonosmotic vasopressin release in the water retention of these edematous disorders. In experimental studies and studies in humans it has been found that the nonosmotic release of vasopressin is consistently associated with activation of the sympathetic nervous and renin-angiotensin-aldosterone systems. Moreover, the sympathetic nervous system has been shown to be involved in the nonosmotic release of vasopressin (carotid and aortic baroreceptors) and activation of the renin-angiotensin system (renal beta-adrenergic receptors). These findings have led to our proposal that body fluid volume regulation involves the dynamic interaction between cardiac output and peripheral arterial resistance. In this context neither total extracellular fluid (ECF) volume nor blood volume are determinants of renal sodium and water excretion. Rather, renal sodium and water retention is initiated by either a fall in cardiac output (e.g. ECF volume depletion, low-output cardiac failure, pericardial tamponade or hypovolemic nephrotic syndrome) or peripheral arterial vasodilation (e.g. high-output cardiac failure, cirrhosis, pregnancy, sepsis, arteriovenous fistulae and pharmacologic vasodilators). With a decrease in effective arterial blood volume (EABV), initiated by either a fall in cardiac output or peripheral arterial vasodilation, the acute response involves vasoconstriction mediated by angiotensin, sympathetic mediators and vasopressin. The slower response to restoring EABV involves vasopressin-mediated water retention and aldosterone-mediated sodium retention. The renal vasoconstriction which accompanies those states that decrease EABV, by either decreasing cardiac output or causing peripheral arterial vasodilation, limits the distal tubular delivery of sodium and water thus maximizing the water-retaining effect of vasopressin and impairing the normal escape from the sodium-retaining effects of aldosterone. The elevated glomerular filtration rate and filtered sodium load in pregnancy allows increased distal sodium and water delivery in spite of a decrease in EABV, thus limiting edema formation during gestation.
