1.Periappendiceal Abscess in a Pre-Term Neonate.
Soonchunhyang Medical Science 2013;19(2):160-162
Acute appendicitis is a common occurrence in childhood. It is very rare in newborns, so it misses the appropriate diagnosis time. Peritonitis due to perforation of acute appendicitis is the cause of death. We report the case of periappendiceal abscess of female premature baby on the age of 23 weeks and 3 days. The baby has abdominal distension and irritability, and she did not respond to antibiotics and conservative treatment. No abnormal findings were found on simple plain radiography and ultrasonography on the abdomen. The clinical manifestations did not improve in spite of conservative care - antibiotics, nasogastric decompression. So diagnostic laparotomy was done. On operation, panperitonitis was found which may be caused by periappendiceal abscess. After ileocecectomy the patient was recovered and gained weight to 2,050 gram. Appendicitis should be considered in the differential diagnosis for a neonate with abdominal distension and bilious vomiting and needs strong clinical suspicion.

The purpose of this study was to investigate the prevalence and characteristics of pre-eruptive intracoronal radiolucencies (PEIR) from panoramic radiographs in Korean children and adolescents.
This study examined panoramic radiographs of 3,000 patients aged between 5 and 14 years old who visited ten dental hospitals in Korea. The age and gender of the patients, the tooth type, the number of intracoronal radiolucent lesions, and the location and size of the lesions were recorded.
The overall prevalence of patients with PEIR was 2.5%. The difference in the presence of PEIR between both genders was not significant. Within each tooth type, the mandibular first molar showed highest prevalence of PEIR (29.6%). The central part of the crown was the most frequently observed location of PEIR (56.8%). The size of the PEIR lesions was mostly limited to less than one-third of the thickness of coronal dentin.

Internal biliary fistula (IBF) is occurred spontaneously due to the biliary disease in most cases. Bilioenteric, biliobiliary, bronchobiliary, and vasculobiliary type of IBF have been reported in the literature. We herein describe our experience with an incidental cholecystojejunal fistula, a very rare type of bilioenteric fistula in laparoscopic cholecystectomy. A 61-year-old woman with several years' history of intermittent right upper abdominal pain was admitted to Soonchunhyang University Cheonan Hospital. Abdominal CT scan showed the pneumobilia in gallbladder with common bile duct dilatation. Endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy were done. On operative findings, there was a cholecystojejunal fistula. We performed laparoscopic cholecystectomy and fistulectomy with jejunal partial resection. To our knowledge, this is the first report on incidental cholecystojejunal fistula uncombined with any other disease and was treated with laparoscopic procedure.

Ovarian cancer is one of the leading causes of cancer-related deaths in gynecological malignancies. Over 70% of ovarian cancer cases are high-grade serous ovarian cancers and have high death rates due to their resistance to chemotherapy. Despite advances in surgical and pharmaceutical therapies, overall survival rates are not good, and making an accurate prediction of the prognosis is not easy because of the highly heterogeneous nature of ovarian cancer. To improve the patient's prognosis through proper treatment, we present a prognostic prediction model by integrating high-dimensional RNA sequencing data with their clinical data through the following steps: gene filtration, pre-screening, gene marker selection, integrated study of selected gene markers and prediction model building. These steps of the prognostic prediction model can be applied to other types of cancer besides ovarian cancer.

PURPOSE: Defensin alpha 6 (DEFA6) is cationic short peptide with known functional activities in innate antimicrobial immunity. DEFA6 is also highly expressed in colorectal cancer tissue. The mechanism and function of DEFA6 have not been reported how to play a significant role in carcinogenesis and cancer progression. The aim of this study was to evaluate the protumorigenic functions of DEFA6 in the colorectal cancer cell line and the clinical significance of DEFA6 expression in colorectal cancer patients.METHODS: DEFA6 expression was investigated by immunohistochemistry in 151 cases of colorectal cancer tissue and the association of DEFA6 expression was correlated with patient's cancer charecteristics.RESULTS: Immunohistochemistry analysis showed that the DEFA6 protein was expressed higher in advanced cancer group (high T stage, patients with lymph node metastasis, patients with vascular invasion) than early cancer group (low T stage, patients without lymph node metastasis, patients without vascular invasion) (P=0.007/0.032/0.047).CONCLUSION: As patient's survival usually depends on migration and invasion of the cancer cell, the high expression of DEFA6 in colorectal cancer cell is associated with patient's cancer charecteristics and could be a biomarker for colorectal cancer. The future study about characterization of DEFA6 will clarify its specific role in oncogenesis and its therapeutic potential.

PURPOSE: Astrocyte elevated gene-1 (AEG-1) plays important roles in tumorigenesis such as proliferation, invasion, metastasis, angiogenesis, and chemoresistance. We examined the expression of AEG-1 in patients with hepatocellular carcinoma (HCC). METHODS: Eighty-five samples were collected from patients with HCC who underwent surgery and were histopathologically confirmed to have HCC. Two independent pathologists, experienced in evaluating immunohistochemistry and blinded to the clinical outcomes of the patients, reviewed all samples. They determined AEG-1 expression semiquantitatively by assessing the percentage of positively stained immunoreactive cells and staining intensity. Clinicopathological data were analyzed in association with prognosis. RESULTS: The association was estimated by univariate and multivariate analyses with Cox regression. Tumor size (hazard ratio [HR], 2.285; 95% confidence interval [CI], 1.175-4.447; P = 0.015), microvascular invasion (HR, 6.754; 95% CI, 1.631-27.965; P = 0.008), and AEG-1 expression (HR, 4.756; 95% CI, 1.697-13.329; P = 0.003) were independent prognostic factors for overall survival. Those for disease-free survival rate were tumor size (HR, 2.245; 95% CI, 1.282-3.933; P = 0.005) and AEG-1 expression (HR, 1.916; 95% CI, 1.035-3.545; P = 0.038). The cumulative 5-year survival and recurrence rates were 89.2% and 50.0% in the low-expressing group and 24.5% and 82.4% in the high-expressing group, respectively. CONCLUSION: The results suggest that AEG-1 overexpression could serve as a valuable prognostic marker in patients with HCC.
