We performed 75 cases of daryocystorhinostomy from Jan. 1988 to Dec. 1990. A routine dacryocystography was performed prior to operation in all cases. A modified T oti's method was applied as a surgical technique "H" shaped incision was done. Both anterior and posterior flaps were sutured adequately and vaseline guaze was used as a plugging agent for 7 to 10 days Success was achieved in 72(96.0%) of 75 cases. The causes of 3-failures were organized granulation tissue and trauma.

Purpose: To evaluate the risk factors for the development of osteonecrosis in civilian professional divers by an epidemiologic study and to determine the correlation between osteonecrosis in divers and coagulopathy by analysis of serologic markers that are related to thrombophilia and hypofibrinolysis. Materials and Methods: Forty-two divers, who collected pen shells (Atrina pinnata), and among whom 10 had osteonecrosis (group 1), were compared with 32 divers without osteonecrosis (group 2). Both groups were evaluated based on the number of years of diving experience, number of dives per year, mean number of dives per day, mean diving time and depth, and diving methods. We determined any statistically significant differences among these variables. We measured the levels of serologic markers that were related to hyperlipidemia, thrombophilia, and hypofibrinolysis from the divers and a control group of 20 physicians (group 3). The levels of the serologic markers were compared between groups 1 and 2 and between the divers and the control group, in order to determine the relationship between the serologic markers and the development of dysbaric osteonecrosis. Results: None of the variables demonstrated any statistically significant differences, except for the mean diving time, in which group 1 had a mean diving time of 124 minutes and group 2 had a mean diving time of 62.1 minutes (P<0.05). In the analysis of the serologic markers, there were no statistically significant differences between groups 1 and 2; however, in comparison with the group 3, the divers demonstrated significantly decreased activity levels of proteins C and S (Protein C: P<0.05; Protein S: P<0.05), and an increase in the levels of plasminogen activator inhibitor-1 (PAI-1) (P<0.05). Conclusion: The divers with osteonecrosis had a longer mean diving time than did those divers without osteonecrosis. In the serologic marker analysis, the divers with osteonecrosis demonstrated significantly decreased activity levels of Proteins C, S and a significant increase in the levels of PAI-1, compared with the control group.

It has been widely accepted that complete surgical resection of hepatoblastoma is essential for long-term survival. But unfortunately less that 50% of hepatic tumors in children can be totally removed at the time of diagnosis. This report is to present the experience of successful resection of hepatoblastoma after concurrent radiotherapy with transarterial chemoinfusion in a child. We believe this modality of treatment enables complete resection of unresectable hepatoblastoma, which is resistant to the systemic chemotherapy.

Juvenile granulosa cell tumor is rare but one of the common congenital testicular neoplasms. Although histological features are typical of its ovarian counterpart, testicular juvenile granulosa cell tumor has a distinctly different clinical presentation. We report a case of juvenile granulosa cell tumor arising in the cryptochid testis of a 4-day-old newborn. A 6 5 5 cm sized multilocular cyst containing thick, mucinous fluid was found in the peritoneal cavity. The external surface of the cyst was smooth and the septae were relatively thin. The cyst consisted of numerous mucin-filled, cystic follicles lined by cells having vacuolated cytoplasm and round to oval dark nuclei without grooves. Cells resembling granulosa cells of an ovarian follicle were also observed in the intervening stroma forming irregular solid nests.

Melorheostosis is a rare disease entity of bone with an etiology and pathogenesis. It cause pain and stiffness in an affected limb, and dense bone formation along the side of bone resembles the flow of candle dripping. Two cases of the disease involving left hand and wrist, and right lower leg are reported with the review of literature.

OBJECTIVES: To perform a systematic review and meta-analysis of the prognostic value of post-treatment 18F-fluorodeoxyglucose positron emission tomography (¹⁸F-FDG PET) in uterine cervical cancer patients treated with radiotherapy (RT) with or without chemotherapy. METHODS: PubMed and Embase databases were searched up to July 22, 2018, for studies which evaluated the response outcomes of ¹⁸F-FDG PET following RT, and their prognostic significance in uterine cervical cancer was assessed with overall survival (OS) or progression-free survival (PFS) as endpoints. Hazard ratios (HRs) were meta-analytically pooled using the random-effects model. RESULTS: Eleven studies with 12 patient cohorts including 1,104 patients were included. For a quantitative synthesis of OS, 7 cohorts were included. Two cohorts which reported disease-specific survival instead of OS were also included with flexibility. Pooled HR of complete metabolic response (CMR) compared to partial metabolic response (PMR) was 0.19 (95% confidence interval [CI]=0.11–0.31). Pooled HR of CMR compared to progressive metabolic disease (PMD) was more evident at 0.07 (95% CI=0.04–0.12), and that of CMR compared to both PMR and PMD was 0.20 (95% CI=0.12–0.34). Quantitative synthesis for PFS was performed with a total of 8 cohorts. Pooled HR of CMR was 0.17 (95% CI=0.10–0.29) compared to PMR, 0.02 (95% CI=0.01–0.06) compared to PMD and 0.12 (95% CI=0.07–0.19) compared to both PMR and PMD. CONCLUSION: Response results of post-RT ¹⁸F-FDG PET were significant prognostic factors in patients with uterine cervical cancer, and ¹⁸F-FDG PET could be a reasonable follow-up imaging modality.

The prognostic factors for extrahepatic biliary atresia (EHBA) after Kasai portoenterostomy include the patient's age at portoenterostomy (age), size of bile duct in theporta hepatis (size), clearance of jaundice after operation (clearance) and the surgeon's experience. The aim of this study is to examine the most significant prognostic factor of EHBA after Kasai portoenterostomy. This retrospective study was done in 51 cases of EHBA that received Kasai portoenterostomy by one pediatric surgeon. For the statistical analysis, Kaplan-Meier method, Logrank test and Cox regression test were used. A p value of less than 0.05 was considered to be significant. Fifteen patients were regarded as dead in this study, including nine cases of liver transplantation. There was no significant difference of survival to age. The age is also not a significant risk factor for survival in this study (Cox Regression test; p = 0.63). There was no significant difference in survival in relation to the size of bile duct. However, bile duct size was a significant risk factor for survival (Cox Regression test; p = 0.002). There was a significant difference in relation to survival and clearance (Kaplan-Meier method; p = 0.02). The clearing was also a significant risk factor for survival (Cox Regression test; p = 0.001). The clearance of jaundice is the most significant prognostic factor of EHBA after Kasai portoenterostomy.

Transhiatal gastric transpositions were performed in two case of long gap esophageal atresia without tracheoesophageal fistula. The patients were a 12 months old female and an 18 months old male. Stamm type gastrostomies were performed at other hospitals in both cases. The stomach was mobilized preserving the right gastric artery, the right gastroepiploic artery and spleen. The proximal and distal esophageal pouches were excised by transcervical and transhiatal route, respectively. The mobilized stomach was pulled up to the neck through esophageal hiatus and posterior mediastinal route. The esophagogastrostomy, the only one anastomosis of this procedure, was performed in the neck. There was no clinical evidence of anastomotic leakage, stricture, regurgitation, difficulty of gastric emptying, hoarseness or respiratory problem. Transhiatal gastric transposition seems to be a safe and easy alternative surgical procedure for esophageal replacement in long gap esophageal atresia.
