Cystic echinococcosis (CE) caused by Echinococcus granulosus is a major public health problem worldwide, including Turkey. The aim of the current study was to identify the strains and to estimate the potential risk factors of E. granulosus in operated pediatric cases in eastern Turkey. Ten pediatric patients (7 boys and 3 girls) living in rural areas, with ages ranging from 3 to 15 years old and various clinical histories, were included in this study. Eight patients had only liver hydatid cyst, while 1 patient had liver and lung hydatid cyst and the other liver, lung, and spleen, together. There were 2 ruptured liver cysts. After surgery, during follow-up, no increase was observed in hemagglutination levels, there were no mortalities, and there was no evidence of recurrence at 2 years post operation in all patients. Molecular analysis was performed on hydatid cyst samples obtained from the 10 pediatric cases. According to mt-12S rRNA PCR results, all cases were found to be G1/G3 cluster of E. granulosus sensu stricto.

Choledochal cyst is considered to be congenital anomalies of the biliary tract, characterized by varying degrees of cystic dilatation at various segments of the biliary tract. A 20-month-old girl was admitted to Eul-Ji general hospital because of abdominal distension. Physical examination revealed marked splenomegaly and hepatomegaly with nodular surface and hard consistency. Laboratory examination showed elevated transaminase level, alkaline phosphatase level and gamma glutamyltranspeptidase level without evidence of cholestasis. Diagnostic imaging study revealed choledochal cyst with Todani classification type 1. Cholecystectomy and Roux-en-Y choledochojejunostomy was performed, and wedge liver biopsy showed diffuse periportal fibrosis with cirrhotic change and ductular proliferation in the portal area. After operation, hepatosplenomegaly and abnormal laboratory examinations improved rapidly, and in 9 months, the liver and spleen became not palpable. We experienced a case of choledochal cyst complicated by liver cirrhosis on pathology in a 20 month-old girl, and removal of choledochal cyst improved clinical manifestations rapidly.

A 10-year-old-girl was referred to our hospital due to abdominal pain. She underwent Roux-en-Y cystojejunostomy for a choledochal cyst at another hospital at the age of 3 months. Abdominal ultrasonography (USG) and computed tomography (CT) showed type I choledochal cyst and multiple gallbladder stones. Because of severe inflammation and adhesion, partial resection of the choledochal cyst and Roux-en-Y hepaticojejunostomy was performed. Two and one half years later, intermittent abdominal pain, fever, nausea and vomiting occured. Abdominal CT scan showed a polypoid nodular lesion in the remnant of the choledochal cyst and probable metastasis at segment 7 of the liver. The duodenum was obstructed by the mass. Liver biopsy revealed moderately differentiated adenocarcinoma. A palliative gastrojejunostomy was performed to relieve duodenal obstruction. She died of hepatic insufficiency 4 months later.

Choledochal cysts have been associated with complications such as cholangitis, pancreatitis, and malignancy of the biliary tract. Recently, the incidence of choledochal cyst in neonate and young infant is increasing due to advances in diagnostic imaging. The aim of this study is to investigate the rationale of excision of choledochal cyst during the neonatal period. The clinical outcome and correlation between age at surgery and the degree of liver fibrosis were reviewed retrospectively. A total of 198 patients with choledochal cyst who were managed surgically between January 1985 and December 2000 at the Department of Surgery, Seoul National University Children's Hospital were included in this study. The overall outcome and the outcome of patients who were managed surgically during the neonatal period were compared. Correlation between age and the degree of liver fibrosis was evaluated by chi-square test and Pearson exact test. The mean age of the patients was 2 years 7 months (ranged from 5 days to 15 years). Mean postoperative follow-up period was 7 years 1 month (7 months to 20 years). The results are as follows. Twelve patients (6%) had postoperative complications, cholangitis (7), bleeding (4) and ileus (1). Eleven patients operated during the neonatal period had no postoperative complications. The positive correlation between age group and degree of liver fibrosis was statistically significant (chi-square: p=0.0165, Pearson exact test: p=0.019). The results support the rationale that excision of choledochal cyst can be performed safely without increasing morbidity in neonates.

In humans, echinococcal species produce cystic lesions primarily involving the liver and lung. Echinococcal infection is caused far more commonly by Echinococcus granulosa than by E. multilocularis, which accounts for less than 5 per cent of all cases of hydatid liver disease. Hydatid disease occurs principally in sheep grazing areas, particularly in the Australia, New Zealand, Greece, Yugoslavia, Middle East, and South American countries, but with increasing migration and traveling, this disease now has a worldwide distribution. This disease is rare in Korea and only few cases have been reported. This is a clinical case report of hydatid cyst of liver caused by Echinococcus granulosus in a 52-year-old man who had been dispatched in the Vietnam from 1966 to 1968.

This study is to get preliminary data for an effectiveness evaluation of abdominal examination and improvement of it. Abnormal cases of abdominal ultrasonography are classified by sex, frequency, diagnosis and age. 4,924 examinees were included at a university hospital of health promotion center from January to December in 1999. The results are as follows. 1. According to the distribution of sex, there are more male patients(55.0%) than females patients(48.0%). For men, 40's showed the highest percentage among examinees. For women, 50's were the highest. 2. The reason that they visited the health promotion center was that 'they wanted to check their health status'. This answers were reported the highest(59.3%). 3. Patients that had abnormal cases of abdominal ultrasonography were 48.3%. Liver, kidney, gallbladder showed the highest percentage of abnormal cases in order of organs. Additionally, abnormal cases were discovered in liver cases. 4. According to the frequency of abnormal cases among examinees, the slight fatty liver were the highest regardless of sex. Men had the slight fatty liver, kidney simple cyst, liver calcification and liver simple cyst in order of abnormal cases. Women showed the slight fatty liver kidney simple cyst, kidney calcification, liver simple cyst, and blood vessel tumor in order of abnormal cases. 5. For the abnormal cases of liver by sex and age, the 50's reported the highest number of abnormal cases in men(299 patients). In addition, 60's had the highest of disease rata 47.8%. For women, 50's reported the highest number of abnormal cases(361 patients). Over 70's patients had the highest of disease rata 52.6%. For kidney, men and women showed the highest number of abnormal cases -62 vs 44 respectively. Over 70's patients had the highest percentage of disease rata-23.2% vs 14.0% respectively. For gallbladder, the number of abnormal cases were the most in men's 60's (31 patients) and in women's in the same age group (32patients). Disease showed the highest percentage in men's 60's(7.6%) and in women's 70's (14.0%). 6. According to malignant tumor, 17patients were liver cancer, 2patients stomach ca and 1pt kidney cancer. 7. The relationship between the malignant tumor and the examination motive was that 'they wanted to check their health status(41.0%)' and 'regular checkup (24.0%)'.

A 15-year-old spayed female Yorkshire Terrier was presented to our hospital with a history of anorexia, depression and abdominal pain. Diagnostic procedures including blood test, radiography and ultrasonography were performed. Abdominal ultrasonography revealed multiple hypoechoic cysts in the left lobe of the liver. Over time, the cysts increased in size and became more echogenic. Four days later, the rupture of the largest cyst was suspected, and hepatic abscesses with bacteria were confirmed by aspiration of the cyst. Despite surgical resection of the abscessed liver lobe, antibiotic administration, and supportive therapy, the dog died 9 days after presentation to the hospital and 4 days after the surgical procedure. The present case report described the overall diagnostic and therapeutic approaches for liver abscesses in a dog.

A 25-year-old Uzbek male presented with right upper abdominal pain for 20 days. On radiologic studies, a huge cystic mass was noticed in the right liver which was suspected as parasitic. The patient received right hepatic segmentectomy (segment 7), and the surgically resected mass was confirmed as cystic echinococcosis (CE), measuring 10.5 cm in its diameter. The inner surface of the cyst was bile-stained. The patient was discharged on the 8th hospital day, and was rechecked 6 months after the surgical intervention without any evidence of recurrence. The present report describes findings of an imported case of CE which represented ultrasound images of the 'ball of wool'.

Echinococcal or hydatid cyst is one of the most important zoonoses and commonly seen throughout the world, especially sheep and cattle raising areas, but rare in Korea. The causative organism, Echinococcus granulosus, is a small tapeworm and dogs are the usual source of infestation. Lung is the second most common focus for this disease, after liver. Recently, with increasing numbers of Koreans visiting to those endemic countries especially Middle East, the reports of hydatidosis are increasing. Authors experienced two cases of pulmonary hydatid cyst in the 31 year old male and 44 year old male who had a history of spending 2 * 3 years in Middle East. we found them in incidental routine chest X-ray.

microRNAs (miRNAs) are small non-coding RNAs that regulate gene expression by targeting the 3'-untranslated region of multiple target genes. Pathogenesis results from defects in several gene sets; therefore, disease progression could be prevented using miRNAs targeting multiple genes. Moreover, recent studies suggest that miRNAs reflect the stage of the specific disease, such as carcinogenesis. Cystic diseases, including polycystic kidney disease, polycystic liver disease, pancreatic cystic disease, and ovarian cystic disease, have common processes of cyst formation in the specific organ. Specifically, epithelial cells initiate abnormal cell proliferation and apoptosis as a result of alterations to key genes. Cysts are caused by fluid accumulation in the lumen. However, the molecular mechanisms underlying cyst formation and progression remain unclear. This review aims to introduce the key miRNAs related to cyst formation, and we suggest that miRNAs could be useful biomarkers and potential therapeutic targets in several cystic diseases.
