Seventy-six children with portal vein obstruction underwent surgical portosystemic shunt, for severe gastrointestinal tract bleeding in 64 and for prophylactic purposes in 12. Endoscopy and angiography or both showed shunt patency in 70 children; thrombosis occurred in the remaining six. The mean age at successful shunt surgery was 6 years 10 months. Early postoperative assessment of shunt patency was judged from regression of splenomegaly and thrombocytopenia when splenectomy was not performed; when done, early postoperative ultrasonography correctly indicated the result. Significant regression of endoscopy was most often delayed postoperatively for up to six months. Children with a proved patent shunt did not have any further episodes of gastrointestinal tract bleeding, displayed no clinical signs of encephalopathy, and often exhibited a striking increase in growth velocity. These results strongly support the contention that a portosystemic shunt is the best treatment for portal vein obstruction after the first spontaneous bleeding episode, even in young children.

Lyme disease, caused by a tick-transmitted spirochete, typically begins with a unique skin lesion, erythema chronicum migrans. Of 314 patients with this skin lesion, almost half developed multiple annular secondary lesions; some patients had evanescent red blotches or circles, malar or urticarial rash, conjunctivitis, periorbital edema, or diffuse erythema. Skin manifestations were often accompanied by malaise and fatigue, headache, fever and chills, generalized achiness, and regional lymphadenopathy. In addition, patients sometimes had evidence of meningeal irritation, mild encephalopathy, migratory musculoskeletal pain, hepatitis, generalized lymphadenopathy and splenomegaly, sore throat, nonproductive cough, or testicular swelling. These signs and symptoms were typically intermittent and changing during a period of several weeks. The commonest nonspecific laboratory abnormalities were a high sedimentation rate, an elevated serum IgM level, or an increased aspartate transaminase level. Early Lyme disease can be diagnosed by its dermatologic manifestations, rapidly changing system involvement, and if necessary, by serologic testing.

From May 1st 1977 until the end of December 1980 35 Warren shunts were performed upon unselected patients with portal hypertension and esophageal varices. According to the Child classification they were divided up into nine Child A, 21 Child B and five Child C cases. Five (14.3) postoperative deaths occurred, yet only one due to technical failure; three patients died of hepatic coma and one of a perforated gastric ulcer. As a postoperative complication recurrent bleeding occurred in six cases (17.1%). Not even one case of pancreatitis could be observed. Fifteen patients were examined at least 6 months after operation. The control angiography (n = 15 = 100%) revealed hepatofugal circulation in only one case; splenomegaly was reduced in ten cases. Only one patient showed clinical signs of encephalopathy, fourteen patients were able to return to their normal activities. The late thrombosis rate was very low-only one case; however, the possibility of conversion to a portocaval shunt remains.

A 64-year-old Turkish male is described with recurrent hepatitic (pre-)coma resulting from a spontaneous porto-spleno-renal shunt, portal hypertension and hepatic insufficiency. In cases of chronic encephalopathy resulting from hepatic insufficiency that may be due to liver cirrhosis, the presence of a spontaneous porto-spleno-renal shunt should be considered as a distinct possibility, not only in the absence of apparent oesophageal varices and splenomegaly, but also when there is hepatopetal flow in the portal vein.

Ultrasound is now widely used in the diagnosis of liver diseases. Applications of ultrasound in the diagnosis of liver cirrhosis are reviewed in this paper. Characteristic findings of liver cirrhosis in ultrasound are nodular liver surface, round edge, and hypoechoic nodules in liver parenchyma which represent regenerative nodules of cirrhotic liver. Detection of hypoechoic nodule more than 10 mm is important in the early diagnosis of hepatocellular carcinoma. Detection of splenomegaly, ascites, and portosystemic collaterals is possible by ultrasound. Evaluation of portosystemic collaterals is beneficial in the management of esophagogastric varices and portosystemic encephalopathy. Ultrasound is useful in the non-invasive diagnosis and long-term management of cirrhotic patients.

At the end of 1984, there were about 1.5 million children worldwide infected with HIV-1. 75% of these children lived in sub-Saharan Africa and Latin America. The rate of mother-to-child transmission of HIV-1 is estimated to range from 13% to 42%. It is twice as high in Africa as it is in Europe. By the year 2000, 6 million pregnant women and 5-10 million children will be infected with HIV-1. It appears that clearance of HIV-1 infection occurs in 2.7% to 6.4% of infected infants. Possible intervention strategies to reduce perinatal HIV-1 transmission include antiretroviral therapy with zidovudine, recommending breast feeding only in areas where it is clearly necessary, cesarean section, passive immunotherapy with anti-HIV immunoglobulins, and viral envelope subunit vaccines. An accurate diagnosis of HIV-1 infection can occur in non-breast fed infants born to seropositive mothers by the age of 3 months. Most children (80-90%) with HIV-1 infection develop features of HIV-1 infection within the first year of life. Common manifestations in the first year are lymphadenopathy, splenomegaly, and/or hepatomegaly. Young infants, especially those 3-6 months old, are more likely to be diagnosed with Pneumocystis carinii pneumonia (PCP) than older HIV-1 infected children. HIV-1 infected children are more likely to develop PCP, serious bacterial infections, cytomegalovirus infection, lymphoid interstitial pneumonitis, and encephalopathy than adults. They are, however, less likely to develop other opportunistic infections (e.g., toxoplasmosis, tuberculosis, cryptococcoses, and histoplasmosis). Possible underlying mechanisms of disease progression in HIV-1 infected children include presence of rapidly replicating syncytium-inducing HIV-1, high virus burden, persistent neutralizing antibody response, antibody-dependent cellular cytotoxicity against HIV-1, and transplacental passage of maternal neutralizing antibodies.

A 59-year-old woman presented with consciousness disturbance with flapping tremor. Laboratory examinations revealed normal liver functions, and imaging studies, ultrasonography, magnetic resonance imaging, and angiography, showed portal vein aneurysm communicating from the portal vein to the hepatic vein, splenomegaly, and splenic artery aneurysm. These examinations confirmed porto-systemic shunt leading to hepatic encephalopathy. Porto-hepatic venous shunt via portal vein aneurysm is extremely rare, and there are few reports that it causes encephalopathy; therefore, little is known about the entity and this association. The literature in English is reviewed and the etiology, clinical features, and prognosis discussed.

A 72-year-old woman was admitted for recurrent episodes of encephalopathy. Laboratory data showed mild liver dysfunction and hyperammonemia, while she had neither anemia nor splenomegaly. The dilated inferior mesenteric vein (IMV) was opacified retrogradely from the superior mesenteric vein by superior mesenteric arteriography, and IMV was found to connect with the inferior vena cava (IVC) through a torturous shunt. No obstruction of the extrahepatic portal vein or hepatic vein was observed by arteriography. Histological evaluation of the liver biopsy indicated remarkable fatty change without cirrhosis. Finally, we diagnosed this case as extrahepatic portosystemic venous shunt without portal hypertension.

The aim of this paper is to describe and discuss, on the basis of a thorough review of the literature, the case of a 70-year-old woman with probable cirrhosis secondary to chronic hepatitis B and C, uncomplicated portal hypertension (without ascites, encephalopathy or bleeding varices), splenomegaly and hypersplenism, and an unusual, spontaneous, large splenorenal shunt and recanalization of the umbilical vein. The tortuous and varicose splenorenal shunt was diagnosed by abdominal ultrasound and CT investigations. A duplex Doppler ultrasonography evaluation was performed to study shunt flow direction and velocity. No gastroesophageal varices were identified on endoscopic examination. The clinical relevance of spontaneous splenorenal shunt, often associated with fundic gastric varices, is discussed.

Idiopathic myelofibrosis may be accompanied by portal hypertension. The authors report a 56-year-old man with idiopathic myelofibrosis and splenomegaly complicated by hepatopathy, severe portal hypertension and recurrent variceal bleeding. A transjugular intrahepatic porto-systemic shunt (TIPS) was inserted. Variceal bleeding never recurred. A short episode of encephalopathy, which is a known complication of porto-systemic shunting, ceased promptly after conservative treatment. The patient eventually died six months later due to metabolic deterioration and hepatic failure related to his underlying hematological disease. TIPS is a promising treatment modality for alleviating symptomatic portal hypertension in hematological disorders.
