1/32. 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.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
2/32. 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.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
3/32. 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.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
4/32. 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.- - - - - - - - - - ranking = 3keywords = infection (Clic here for more details about this article) |
5/32. 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.- - - - - - - - - - ranking = 6keywords = infection (Clic here for more details about this article) |
6/32. 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.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
7/32. Renal involvement in prolonged salmonella bacteremia: the role of schistosomal glomerulopathy.Renal involvement has been well documented in patients with hepatosplenic schistosomiasis and in patients with prolonged salmonella bacteremia (PSB). Whether there is a specific renal lesion related to PSB or the chronic bacterial infection aggravates a pre-existing schistosomal glomerulopathy has been a matter of controversy. To analyze the clinical manifestations and histopathological findings of the renal involvement, 8 patients with hepatosplenic schistosomiasis and PSB (group I) were compared with 8 patients with schistosomal glomerulopathy (group II) matched by sex and glomerular disease. The mean age in group I was 17.7 years. All patients presented with hematuria, in 4 cases associated with non-nephrotic proteinuria. In group II the mean age was 23 years; nephrotic syndrome was the clinical presentation in 7 of the 8 patients in the group. All patients in group I experienced remission of the clinical and laboratory abnormalities as the salmonella infection was cured; in group II the patients had persistent, steroid-resistant, nephrotic syndrome. On histological examination, no difference was noted between the two groups, except for pronounced glomerular hypercellularity and interstitial mononuclear cell infiltration in group I. These observations strongly suggest that PSB exacerbates a pre-existing sub-clinical schistosomal glomerulopathy by the addition of active lesions directly related to the prolonged bacteremia.- - - - - - - - - - ranking = 2keywords = infection (Clic here for more details about this article) |
8/32. Serologic findings in hepatic ascariasis: a case report.A 56-year-old Japanese woman underwent partial hepatectomy for intrahepatic cystic masses. Before operation, the patient had been diagnosed as liver abscess due to ascaris infection serologically. The excised hepatic lesions consisted of encapsulated old abscesses, with a few calcified parasitic ova and numerous Charcot-Leiden's crystals microscopically seen in necrotic exudate. However, no parasitic worms were found in the cystic cavity. The eggs in the tissues were indistinguishable from other helminthic ova morphologically, but stained positively for ascaris antigens by the indirect immunoperoxidase method. The results indicate that the serologic diagnosis of intrahepatic ascariasis may be feasible, practical, and reliable.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
9/32. An unusual cause of recurrent biliary colics.Hepato-biliary ascariasis is a rare condition in non-endemic areas; however, it should always be taken into account in patients with recurrent biliary colics and/or cholangitis, since these are among the most frequent modes of clinical presentation. We report a case of a young woman suffering from recurrent biliary colics in whom a diagnosis of biliary ascariasis was made. Endoscopic retrograde cholangiopancreatography with sphincterotomy and endoscopic extraction of the worm, using a Dormia basket, proved to be a safe and effective procedure for removing the living ascaris from the biliary tree and relieving symptoms. In the era of worldwide travels, physicians in Western countries should be more aware of this infection especially in patients with biliary symptoms who have travelled to endemic areas or immigrant from endemic countries.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
10/32. Hepatic capillariasis in maine presenting as a hepatic mass.We report the first case of hepatic capillariasis in maine. The patient was a 54-year-old male carpenter who presented with a subacute history of severe abdominal pain, fevers, and weight loss. Initial diagnostic studies suggested a hepatic mass associated with para-aortic lymphadenopathy. The patient underwent open laparotomy for resection of the mass. He was found to have an eosinophilic granuloma in the liver; further evaluation revealed degenerating capillaria hepatica. The exact route of infection in this case is unknown but is most likely due to accidental ingestion of soil contaminated with mature capillaria eggs. This patient had a low parasite burden and did not exhibit significant peripheral eosinophilia. After treatment with thiabendazole, he recovered uneventfully.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
