1/10. Hepatic calcification by sequelae of chronic schistosomiasis japonica: report of four cases.Due to the elimination of intermediate hosts and the improvement of clinical care, most parasitic infections have been effectively controlled in developing countries. Recently, the increase of the worldwide tourism, especially to Mainland china, and the migration of overseas workers from endemic countries have led to more parasitic infections that should not be overlooked by physicians. Assessment of diffuse liver disease with physical examination and laboratory findings is notoriously inaccurate. Thus, physicians use liver biopsy for accurate diagnoses. We present 4 patients with hepatic schistosomiasis japonica which were diagnosed using imaging before liver biopsy. Hepatic schistosomiais japonica has a tendency to cause dystrophic calcification and fibrosis in the liver. According to the results, a combination of ultrasonography and computed tomography (CT), used to recognize characteristic calcification patterns, seem useful to physicians for accurate diagnoses. Thus, unnecessary biopsy procedures can be avoided.- - - - - - - - - - ranking = 1keywords = japonica (Clic here for more details about this article) |
2/10. 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 = 0.83333333333333keywords = japonica (Clic here for more details about this article) |
3/10. cholangiocarcinoma coincident with schistosomiasis japonica.The relationship of parasitic liver disease to cholangiocarcinoma has long been debated, and it has been reported that cholangiocarcinoma is associated with opisthorchiasis viverrini. We report herein a rare case of cholangiocarcinoma associated with schistosomiasis japonica. A 76-year-old Japanese man with jaundice was diagnosed with cholangiocarcinoma. Radical resection was not done because of hepatic arterial and portal vein invasion. Biliary microwave tissue coagulation therapy was performed with placement of a metallic stent endoprosthesis. Twenty-two months after the treatment, however, the patient died from hematemesis. autopsy findings revealed that there was no distant metastasis, even in the area of regional lymph node metastasis. The primary tumor in the hepatic hilar region had been replaced by necrotic debris resulting from the microwave therapy, and an expandable metallic stent was located in the center of the debris. Histological findings showed schistosome eggs, which were old and microcalcified, in veins in the colonic submucosa. Glisson's fibrosis around the cancer lesion suggested that schistosomiasis japonica and cholangiocarcinoma can occur together with severe chronic inflammation of the portal vein.- - - - - - - - - - ranking = 1keywords = japonica (Clic here for more details about this article) |
4/10. Determination of the period for establishment of a liver network echogenic pattern in schistosoma japonicum infection.Schistosomiasis is caused by infection with schistosoma haematobium, S. mansoni, S. japonicum, or S. mekongi. S. japonicum infection results in liver cirrhosis at the final stage. A "network" (NW) echogenic pattern on hepatic ultrasonography appears to be specific to S. japonicum infection. The principal aim of the present study was to determine the exact year(s) or even month(s) required for the establishment of the liver NW echogenic pattern from the initial infection in young patients with schistosomiasis japonica since there are few data on this important point. We conducted yearly ultrasonographic, serologic, coprologic, and physical examinations of schistosomiasis patients in the philippines from 1996 up to the present. During that period, the total number of patients examined was approximately 2,000, among whom we selected 2 patients for determination of the duration required for NW establishment, when they were 10 years old. Although the exact time of initial exposure to schistosomes cannot be determined, the duration for the establishment of NW was definitively confirmed in patient no. 1 to be between 19-24 months based on the results of serologic and coprologic examinations. For patient no. 2, the circumstantial evidence suggested that the establishment of a NW might require 5 to 6 years at maximum. To the best of our knowledge, this is the first evidence-based report on the determination of the period required for the establishment of a liver NW echogenic pattern in S. japonicum infection in the philippines.- - - - - - - - - - ranking = 0.16666666666667keywords = japonica (Clic here for more details about this article) |
5/10. Sigmoid colonic carcinoma associated with deposited ova of schistosoma japonicum: a case report.We report a case of sigmoid colonic carcinoma associated with deposited ova of schistosoma japonicum. A 57-year old woman presented with a 10-mo history of left lower quadrant abdominal pain and a 2-mo history of bloody stools. She had a significant past medical history of asymptomatic schistosomiasis japonica and constipation. A colonoscopy showed an exophytic fragile neoplasm with an ulcerating surface in the sigmoid colon. During the radical operative procedure, we noted the partially encircling tumor was located in the distal sigmoid colon, and extended into the serosa. Succeeding pathological analysis demonstrated the diagnosis of sigmoid colonic ulcerative tubular adenocarcinoma, and showed deposited ova of schistosoma japonicum in both tumor lesions and mesenteric lymph nodes. Three days after surgery the patient returned to the normal bowel function with one defecation per day. These findings reveal that deposited schistosome ova play a possible role in the carcinogenesis of colorectal cancer.- - - - - - - - - - ranking = 0.16666666666667keywords = japonica (Clic here for more details about this article) |
6/10. Turtleback liver on CT and ultrasound: Schistosoma japonica revisited.Schistosomiasis in its many forms still presents a major public health challenge. Its tendency to cause dystrophic calcification makes it ideal for radiologic study. With population movement the disease may be encountered in unexpected countries especially with the sensitivity of CT to the presence of calcium. S. japonica produces pathognomonic "turtleback" calcification in the liver, in association with hepatic fibrosis but not necessarily cirrhosis. This paper illustrates a classic case and reviews the literature.- - - - - - - - - - ranking = 0.83333333333333keywords = japonica (Clic here for more details about this article) |
7/10. Disappearance of specific antibodies in patients with chronic schistosomiasis japonica by treatment with praziquantel.We tested effects of praziquantel, an antischistosomal compound, on clinical and immunological parameters of chronic schistosomiasis japonica. Two Japanese patients, who had high antibody titers to schistosoma japonicum antigens but no fecal schistosome eggs or no or mild symptoms complained, were treated with praziquantel. Within two years after treatment, anti-schistosome antibodies in sera from the patients became negative in enzyme-linked immunosorbent assay. There was no significant alteration in cellular immunity to the parasite. Although S. japonicum infection is believed to have been eradicated in japan, our present results seem to suggest the possibility that a few Japanese individuals, who have high anti-schistosome antibody, still harbor live parasites.- - - - - - - - - - ranking = 0.83333333333333keywords = japonica (Clic here for more details about this article) |

9/10. A case of microhepatoma associated with schistosomiasis japonica diagnosed by enhanced ultrasonography after hepatic intraarterial injection of carbon dioxide gas.The patient was a 58-year old man whose complaints were generalized malaise and right epigastralgia. He had liver cirrhosis and schistosomiasis japonica, previously diagnosed by laparoscopy. Computed tomography (CT) showed a high density funicular shadow in the liver. However no tumorous lesions in the liver were visualized. ultrasonography (US) of the liver showed a reticulate or scaly pattern, but no images of tumorous lesions. Hepatic angiography showed a single, deeply colored image about 1cm in diameter, in the segmentum anterosuperior. Preoperative and intraoperative enhanced US with hepatic intraarterial injection of carbon dioxide gas was performed. It showed a hyperechoic tumor shadow about 1cm in the segmentum anterior. The segmentum anterosuperior including the tumor was partially resected. Pathologically, the tumor was found to be a hepatoma of Edmondson type II, caused by cirrhosis and schistosomiasis japonica. The patient's postoperative course was uneventful. Enhanced US with hepatic intraarterial injection of carbon dioxide gas was useful for the diagnosis and treatment of the microhepatoma associated with schistosomiasis japonica.- - - - - - - - - - ranking = 1.1666666666667keywords = japonica (Clic here for more details about this article) |
10/10. Preeclampsia with fetal death in a patient with schistosomiasis japonica.A case of preeclampsia with fetal death at 32 weeks' gestation is reported. Liver examination of the patient revealed network patterns on ultrasonography and linear calcifications on unenhanced CT scans in the liver. These findings are typical of those of chronic schistosomal infection. Indeed, liver biopsy specimens showed eggs of schistosoma japonicum. We diagnosed her case as preeclampsia with liver cirrhosis due to chronic schistosomiasis japonica. Schistosomal placentitis may have been present and may have contributed to preeclampsia and fetal death.- - - - - - - - - - ranking = 0.83333333333333keywords = japonica (Clic here for more details about this article) |
