Cholecystitis due to helminthic infection

Helminthic infections were reported from tropical and subtropical locations in the world. The parasitic helminths develop and migrate to different organs. Unusual cases may afflict the gallbladder and the biliary tract. The parasites invade the bile ducts and cause inflammation, fibrotic lesions, acute and chronic cholecystitis. In this article, we reported three unusual cases of parasitic infection in Kermanshah, Iran. The worms were isolated from gallbladder and biliary tract. The specimens were diagnosed by macroscopic features and staining methods. Ascaris lumbricoides, Taenia saginata and adult type fasciola hepatica isolated from gall bladder and biliary duct. Cholecystectomy was done on all patients suffering from gall bladder inflammation and obstruction

Study of operated primary and secondary [recurrence] hydatidosis in hospitals of Kermanshah, west of Islamic Republic of Iran

Cystic echinococcosis, caused by the larval stage of Echinoccocus granulosus, is a global public health threat. The aim of this study was to determine the demographic and clinical characteristics of cases of primary and secondary hydatid cyst in the west of the Islamic Republic of Iran. A retrospective record review was made in 7 public and private hospitals in Kermanshah from 2004 to 2009. Of 526 files of suspected cases analysed, 291 cases of hydatid cyst had been operated upon and confirmed. Of the patients, 51.5% were females, 57.7% lived in urban and suburban areas and the largest age group [17.5%] was 31-40 years. The major organs involved were liver [64.9%] and lung [26.8%] and 18 cases [6.2%] were confirmed as secondary hydatidosis. Most patients [79.4%] had been treated with albendazole.Kermanshah province should be considered an endemic region for human hydatid cyst disease; greater efforts in prevention are needed

trend of hydatidosis in Kermanshah province, western Iran [1986-2008]

Hydatidosis is the larval stage of the Echinococcus granulosus. This disease is endemic in Iran. There are many studies about hydatidosis in different regions of the country, but there is not any information about the disease in Kermanshah Province. This article will review all available data about hydatidosis in this province. Using web based search engines and a survey on medical student's theses, all the information about hydatid cysts in the province from 1986 -2008 was collected. During these twenty years, at least 482 proven cases of hydatid cyst have been identified in the province. Accordingly, the trend of hydatid cyst operation in the province has been growing and the average annual number of cases has reached 1.41/100,000. Frequency of disease in urban areas was slightly higher than rural areas and the rate of infection in housewives was more than others. Because of the growing trend of hydatid cyst operation in Kermanshah Province, which may be due to many different reasons, this province should be considered as one of the important endemic regions of hydatidosis in Iran
