Two dogs were referred with the clinical signs of depression and constipation, respectively. One dog with depression had hypoglycemia on biochemistry. On survey abdominal radiographs, a soft tissue density round mass with calcified spots was identified cranial to the urinary bladder. On ultrasonographs, a solitary oval heterogeneous complex-echoic mass with well-defined margin was found. On surgery, the mass was pedunculated and originated from the colonic wall. The resected mass was confirmed as colonic leiomyoma. The other dog with constipation had normal CBC and biochemistry values. On survey abdominal radiographs, there was a soft tissue density round mass dorsal to the descending colon and rectum. The descending colon was displaced ventrally and narrowed by the mass. On ultrasonographs, a well-defined round heteroechoic mass compressed the colon. The mass was also pedunculated and originated from the colonic wall on surgery and confirmed as colonic leiomyoma. Two dogs recovered without any clinical signs after surgery and showed permanent resolution of the clinical signs, respectively.

A 10-year-old intact female Yorkshire terrier dog was referred for evaluation of marked abdominal distension and hemorrhagic effusion. Abdominal radiography and ultrasonography demonstrated abdominal effusion and intraabdominal mass with anechoic cystic components. On ascites cytology, neoplastic epithelial cells with vacuolated cytoplasm and prominent nucleoli were identified. Magnetic resonance imaging (MRI) showed the well-defined, heterogeneous, and large mass filled the intraabdominal cavity. At necropsy, a large mass arising from the right ovary was observed. Histopathologically, the mass was composed of papillary structures lined by neoplastic epithelial cells. The dog was definitively diagnosed as malignant ovarian adenocarcinoma with papillary pattern based on clinical and histopathological findings.

A 1.5-year-old, female domestic rabbit was diagnosed with uterine torsion accompanying hydrometra of the right uterine horn and pyometra of the left horn. The exploratory laparotomy revealed the torsion of bilateral uterine horns in the region of the uterine cervix. No growth was detected in fluid collected from the right horn of the uterus; however, Gram-positive micrococcus and bacilli were cultured from the left horn. The pathophysiology of the simultaneous occurrence of these disorders was suspected considering that abdominal distension progressed over 4 months and the rabbit's condition deteriorated abruptly within 2 days, hydrometra was the initial disease and then infection to the left uterine horn and torsion developed later due to the large volume of fluid within the uterus. This report is the first case showing uterine torsion accompanying hydrometra and pyometra in each uterine horn.

We report a case of a patient with necrotizing fasciitis followed by liver abscess. A 51-year-old man was admitted to our hospital with a 5-day history of fever and chills with painful swelling of the right thigh. A magnetic resonance imaging (MRI) scan showed fluid collection with numerous dark signal intensities considered as air-bubbles between the posteromedial and posterolateral groups of the right thigh, resulting in presumptive diagnosis of necrotizing fasciitis. At the time of admission, an ultrasonograph of the abdomen showed increased parenchymal echogenicity of both kidneys and no liver abscess. Ten days after fasciotomy, an abdominal computed tomography (CT) scan showed intrahepatic abscess. Sonography-guided percutaneous drainage was performed. Both cultures of pus specimens from the liver abscess and right thigh yielded Klebsiella pneumoniae (K. pneumoniae). The patient was treated with fasciotomy several times and parenteral antibiotics, after which he began to improve. After 5 weeks, liver abscess size was reduced, and after 10 weeks, liver abscess disappeared. To the best of our knowledge, this is the first case of K. pneumoniae-necrotizing fasciitis followed by liver abscess.

Purpose : The renal manifestations of tuberous sclerosis complex (TSC) are remarkably diverse, including polycystic kidney disease, simple renal cysts, renal cell carcinomas, and angiomyolipomas. All of these occur in children as well as adults in TSC. Angiomyolipomas, which can cause spontaneous life-threatening hemorrhages, are by far the most prevalent and the greatest source of morbidity. Here, we will address our experience, adding to the literature on pediatric patients with TSC requiring evaluation and treatment for renal manifestations. Methods : A retrospective analysis was made on 19 patients in whom TSC was diagnosed between May 2001 and Oct. 2005 at Severance Hospital. All patients had clinical diagnoses of TSC as defined by the 1998 tuberous sclerosis complex consensus conference. Results : The patients consisted of 13 boys and 6 girls with a mean age of 7.3 years (range 1 to 22). The renal disease associated with TSC included angiomyolipoma in nine patients (47.4 percent), renal simple cyst in one (5.3 percent), hydronephrosis in one (5.3 percent) patient. Eight patients (42.1 percent) presented with normal kidney contours at abdominal ultrasonography. One patient underwent renal replacement therapy due to chronic renal insufficiency after nephrectomy. Hemorrhage from angiomyolipoma was not detected. Conclusion : In our review of 19 cases of TSC, renal manifestations are reported in 57.9 percent of patients. Asymptomatic angiomyolipoma associated with TSC grow gradually, although severe hemorrhages are rare. So patients with TSC should be followed up with serial computerized tomography or abdominal ultrasonography. And also, renal function should be monitored conservatively.

In Korea, Clonorchis sinensis infection is still highly prevalent because case detection in the field is difficult and the detected cases used to be incompletely cured due to treatment failure. The present study tried to control clonorchiasis in an endemic village by repeated treatments with praziquantel every 6 months and to evaluate sonography as a diagnostic measure. By stool examinations, the egg positive rate in the endemic village was 22.7％, but it decreased to 19.6％ at 6 months. 15.1％ at 12 months, 12.2％ at 18 months, 6.3％ at 24 months, 11.4％ at 30 months, and 6.3％ at 42 months after the beginning of repeated praziquantel administration. The sonography showed 61 (49.6％) positive cases of 123 screened residents; among egg-positives the sonography positive rate was 52.2％ and among egg-negatives it was still 49％. The rate among cured cases was 64.3％ after 6 months, 50.0％ after 12 months, 50.0％ after 18 months, and 66.7％ after 24 months. In a non-endemic village, 64 residents were found egg-negative by fecal examination, but 20 (31.3％) of them were positive by sonography. The present findings indicate that control of clonorchiasis in an endemic village by repeated praziquantel treatment for 42 months is still insufficient and sonography is of little value for diagnosis of clonorchiasis.

Nonalcoholic fatty liver disease (NAFLD) is accumulation state of fat in liver cells without excessive alcohol intake, and it has been studied that is closely related to obesity. The purpose of this study is to identify risk factors for NAFLD and may prevent or to manage risk factors. This study was in progress for six months (2011 May 1 to October 31), of the 83 people who underwent abdominal ultrasound 11 people eventually were selected. Research results was as follows : First, the decreased body weight and body mass index (BMI), and the second, a decrease of the deepening of fatty liver in ultrasound diagnosis, and the third, steady movement reduces the deepening of fatty liver regardless of calories. Thus, the implication of this research is that long-term exercise programs have positive effects in the treatment of fatty liver.

Purpose : Neutropenic enterocolitis is an acute, life-threatening inflammation of the small and large bowel, often seen in children with malignancies during periods of prolonged or severe neutropenia. The optimal management for typhlitis in pediatric oncology patients has been debateful between operative and nonoperative approaches. The purpose of this study was to review the outcome of medical management of patients who were diagnosed as typhlitis. Methods : The records of 207 pediatric cancer patients who were diagnosed and treated at the pediatric department of Yeungnam University Hospital for cancer between August, 2002 and July, 2007 were reviewed. Results : Among 207 patients, 12 (5.7%) children aged 9 to 14 years, were diagnosed clinically to have typhlitis. Clinical symptoms and signs of patients were fever, abdominal pain and tenderness, diarrhea, vomiting and rebound tenderness. Bowel-wall thickening (> 4mm) was seen on CT or ultrasonography. All patients were treated with antibiotics combinations of teicoplanin, carbapenem, aminoglycoside, or other third generation cephalosporin and metronidazole or clindamycin. Eight patients were treated with additional antifungal agents. Other supportive management included bowel rest, total parenteral nutrition, and G-CSF administration. All patients recovered completely and did not need any surgical management. Conclusion : Early diagnosis and aggressive supportive treatment appears to be important for complete recovery and survival of typhlitis.

The purpose of this study was to investigate the relationship between abdominal subcutaneous fat thickness(ASFT) and maternal gestational diabetes mellitus(GDM) measured by ultrasound at period of pregnancy. We compared maternal age, pre-pregnancy body mass index, and weight gain during pregnancy in 286 pregnant women who were diagnosed with early pregnancy ASFT and high GDM screening test(50 g OGTT) of more than 140 mg/dL. ROC curve analysis was used to determine the cut-off value of ASFT for GDM prediction. Maternal age and weight gain during pregnancy were not related to GDM in the mid-trimester and pre-pregnancy body mass index and earely pregnancy ASFT were significantly different between normal and GDM high risk groups. The cut-off value of ASFT for GDM prediction was 2.23 cm(AUC 0.913. Sensitivity 76.19%, Specificity 93.72%). ASFT measured by ultrasound in early pregnancy was useful as an important index for predicting mid-trimester GDM prediction. Therefore, ASFT can be used as an auxiliary diagnostic index for early recognition of GDM.

Purpose: Alvarado scoring system was evaluated regarding its usefulness for the early diagnosis of acute appendicitis in adult and in reduction of the incidence of negative appendicectomies. To evaluate the accuracy of diagnosing appendicitis using the Alvarado score in children. Methods: Prospectively, we surveyed 122 patients (male 67, female 55) suffering from abdominal pain, who had visited to the emergency department of Chosun University Hospital from June 2002 to May 2003. The Alvarado score has been computed from the white blood cell count, neutrophil count, body temperature, resistance in the right lower quadrant, length of symptoms, nausea and vomiting. Each patient was evaluated by a pediatric resident and then by a general surgeon independently. Results: Out of 170 total children who visited to the emergency department due to abdominal pain, 122 patients were associated with appendicitis. A total of 122 patients (67 male and 55 female) were visited to the emergency room with suspected appendicitis. From 105 operated patients, 92 (87.6%) were diagnosed acute appendicitis and erronous diagnostic rate was 12.4%, pathologically. Mean alvarado score of appendicitis group was $5.40{\pm}1.24$ whereas those of non-appendicitis group was $3.73{\pm}1.82$ (p<0.05). From 6 Alvarado score high sensitivity (86.4%) and high specificity (80.0%) were observed. Sensitivity of ultrasonography or computed tomography was 92.5%. Conclusion: We found that Alvarado score system is a noninvasive, safe diagnostic method, which is simple, reliable and repeatable. Alvarado score is useful system for a first, rapid and economic evaluation for the appendicitis in children.
