1/77. Hepatic capillariasis in children: report of 3 cases in brazil.

    capillaria hepatica is a helminth that may cause an extremely rare condition of parasitic hepatitis. Only 29 cases have been published, 2 of them in brazil. We report here 3 cases of children in brazil with massive hepatic capillariasis who presented the characteristic triad of this type of infection, i.e., persistent fever, hepatomegaly, and eosinophilia. The diagnosis was made by liver biopsy. All children responded well after treatment with thiabendazole (case 1), albendazole (case 3), and albendazole in combination with a corticoid (case 2). Case 1 has been followed-up for 24 years, an event not previously reported in the literature. ( info)

2/77. capillaria hepatica parasitism.

    capillaria hepatica is rarely encountered in humans, with fewer than 30 documented cases. The clinico-pathological features of capillaria hepatica infection, diagnosed on liver biopsy of a 6-year-old child are discussed. Pathologically, it is characterised by prominent granulomatous lesions in the liver surrounding the eggs, which on cursory examination may be confused with schistosoma mansoni. ( info)

3/77. leishmaniasis diagnosed by liver biopsy: management of two atypical cases.

    Two patients presenting with pyrexia of unknown origin were diagnosed as having visceral leishmaniasis based on the presence of leishmania donovani bodies in liver tissue. Of particular interest is that these two case reports suggest that in patients with pyrexia of unknown origin, a liver biopsy for L. donovani bodies should be considered even when several months have passed since leaving an endemic area, when splenomegaly is absent, when bone marrow examination and serology are not diagnostic, and even when abnormal coagulation necessitates a transjugular liver biopsy.

4/77. Severe hepatic involvement in visceral larva migrans.

    Because of its anatomical position, the liver may be involved in many protozoan and helminthic gastrointestinal infections. Visceral larva migrans caused by toxocara canis is rarely taken into account in adult patients with cholestatic syndrome, especially when liver disease is not associated with hypereosinophilic reaction. We report on a 74-year-old immunocompetent woman who presented with fever, bronchospasm, erythema nodosum, weight loss and progressive jaundice. A liver biopsy showed caseating granulomatous hepatitis with secondary portal fibrosis and paucity of interlobular bile ducts. A step-by-step search for aetiological factors led us to a diagnosis of toxocariasis (positive enzyme-linked immunosorbent assay IgG test). An excellent clinical response to combined treatment with steroid and diethylcarbamazine, and a reduction in the antibody level against T. canis supported the diagnosis. Computed tomography and laparoscopy demonstrated multiple small mass lesions and fibrous perihepatitis. This report shows that visceral larva migrans may be a cause of prostrating chronic liver disease and should be suspected in every febrile patient with cryptogenic cholestatic hepatitis. ( info)

5/77. Hepatic schistosomiasis japonica in a patient with gallstones and bile duct stones--a case report.

    Schistosomiasis, a common parasitic disease in many countries, is found as imported cases in taiwan. Responsible for human infections are five species, one of which, schistosoma japonicum, is currently endemic in china and South-east asia. Chronic infection with S. japonicum may lead to the development of liver fibrosis, calcification and portal hypertension. Under investigation by sonography and computed tomography (CT) scan, a peculiar "turtle-back" appearance of liver fibrosis and calcification may be found. Herein, we report a case referred to our department due to jaundice. The sonography of liver showed typical "turtle-back" appearance. gallstones and bile duct stones were also found in this case. Surgical interventions with percutaneous transhepatic biliary drainage (PTBD), cholecystectomy and choledocholithotomy were performed to relieve the obstructive jaundice and remove the stones. There were no parasitic eggs in the extracted stones or in drained bile juice. However, deposits of calcified S. japonicum eggs in liver parenchyma and portal tracts were identified in liver biopsy. No special treatment was given for the schistosomiasis japonica because the calcified parasitic eggs were the sequelae of past infection. ( info)

6/77. Right hepatic segmentectomy for the treatment of intrahepatic biliary stones due to ascaris lumbricoides: report of a case.

    We report herein the case of a 46-year-old woman investigated for recurrent acute cholangitis. Ultrasound, endoscopic retrograde cholangiopancreatography, and computed tomography scan revealed dilatation and multiple images suggestive of intrahepatic biliary stones in the ducts that drained segments V and VI of the liver. Endoscopic treatment was attempted unsuccessfully, and based on the severity of the last crisis of cholangitis a laparotomy was performed. A right hepatic lobectomy including segments V and VI was carried out without any complications, resulting in complete relief of symptoms. Pathological examination of the liver demonstrated the presence of worm nests in the liver parenchyma with chronic granulomatous lesions. ( info)

7/77. Biliary ascariasis with acute hemorrhagic pancreatitis: a case report.

    A case of acute hemorrhagic pancreatitis associated with biliary ascariasis in a 35 year old man is reported. Clinical presentation and laboratory investigation along with management outcome are discussed. ( info)

8/77. Visceral larva migrans due to ascaris suum which presented with eosinophilic pneumonia and multiple intra-hepatic lesions with severe eosinophil infiltration--outbreak in a Japanese area other than Kyushu.

    A 32-year-old man presented with the chief complaint of severe cough. Examination of peripheral blood showed a marked increase in eosinophils. Chest CT demonstrated multiple ground glass opacities in both lungs. bronchoalveolar lavage showed abundant eosinophils. Abdominal CT demonstrated multiple low attenuation areas in the liver. liver biopsy with ultrasonography revealed severe eosinophil infiltrations around the portal veins. Serologically, a multi-dot enzyme linked immunosorbent assay (DOT-ELISA) and ELISA inhibition test using microtiter plates were positive for ascaris suum. Thus, visceral larva migrans due to ascaris suum was diagnosed. Outbreaks of this disease in japan have previously been confined to the Kyushu area. The present case which occurred outside that area, illustrates the importance of constant attention to the epidemiology of this disease. ( info)

9/77. Active hepatic capsulitis caused by paragonimus westermani infection.

    paragonimiasis is an important re-emerging parasitosis in japan. Although the lungs and pleural cavity are the principal sites affected with the parasite, ectopic infection can occur in unexpected sites such as skin and brain. This case report describes a patient with active hepatic capsulitis due to paragonimus westermani infection. The patient was successfully treated with praziquantel at the dose of 75 mg/kg/day for 3 days. ( info)

10/77. The first human case of hepatic dirofilariasis.

    Most of human dirofilariasis are pulmonary or subcutaneous infections, but there have been a few reports of human dirofilariasis in unusual sites, such as large vessels, mesentery, peritoneal cavity, and spermatic cord. We present the first case of human hepatic dirofilariasis, which was surgically diagnosed. A 39-year-old man without any evidence of systemic symptom was found incidentally to have a hepatic nodule during routine physical check-up. The histologic findings of the resected lesion showed a granulomatous lesion with central necrosis containing up to 35 transverse sections of a nematode, ranging 30-80 micro m in diameter. Thin (1.5-5 micro m) cuticle with transverse striations surrounded polymyarian and muscle bundles occupied a sixth of both sides of outer body cavity. Central portion of the body cavity was occupied with an intestine-like tubular structure and a larger reproductive tube. These microscopic findings were consistent with degenerated dirofilaria immitis. Antibody test by enzyme-linked immunosorbent assay for patient serum reacted positively against adult D. immitis antigen. ( info)
