Conventional Conjunctivodacryocystorhinostomy[CDCR]which is performed for canalicular obstruction or failed DCR, is well known as one of the most effective treatment modalities. The authors compared surgical results of endoscopic with those of conventional method to evaluate advantages of endoscopic method over conventional CDCR and important success factors. Primary success rates were 90%[86/96]in endoscopic method and 86%[214/217]in conventional method. Final success rates were 97%[93/96]and 96%[237/247]in endoscopic and conventional method, respectively[p>0.05]. We considered that endoscopic method was superior to conventional method in accurate measurement of Jones tube length at the time of endoscopic operation. It was considered the most important success factor.

This paper describes a case of intrapericardial teratoma in a 20-day-old female meonate, who suffered from cyanosis and respiratory difficulty. She was evaluated by echocardiography, chest CT and MRI, the suspected cyanosis and respiratory difficulty. She was evaluated by echocardiography, chest CT and MRI, the suspected intrapericardial mass was identified and surgically removed. The postopervative diagnosis was intrapericardial teratoma, grade II. This case is reported with brief review of some related literature.

Neuromyelitis Optica(Devic's Disease) is characterized by a disease process that is relatively afebrile and strictly limited to the spinal cord and optic nerves. We experienced a case of neuromyelitis optica characterized by binocular blindness and paresthesia below the umbilicus level with paraplegia of both lower legs associated with urinary incontinence and defication difficulty. We report above case with brief review of literatures.

We studied the relationship among hypertension and retinal and retinal vessel change of 200 hypertensive out and in patients in Seoul Red Cross Hospital. The results are: 1) About 50% of hypertensive patients fall in 2nd stage hypertensive retinopathy. Systolic blood pressure is proportion to hypertensive retinopathy. 2) Generalized narrowing accounts for 86% of retinal vessel change, focal constriction 36.5% and increased central reflex accounts for 68%. 3) Concealment account for 57.5% of A-V crossing sign and anterior displacement accounts for 34%. 4) The commonest site of A-V crossing is inferior-temporal branch and superior-temporal branch come after. The former accounts for 45.3% of A-V crossing and the latter accounts for 36.8%. 5) In grade m retinal changes, puntate hemorrhage accounts for 30. 6% of retinal hemorrhages, flame shaped hemorrhages 32.1% punctate exudates 32.1% and cotton-wool patches accounts for 39%.

Telomerase play a key role in the maintenance of telomere length and chromosome integrity. We have evaluated the association between telomerase activity and the risk of lung cancer in peripheral blood. Telomerase activity in peripheral blood mononuclear cells was measured by a PCR-designed telomeric repeat amplification protocol in 63 lung cancer patients and 190 healthy controls that were matched for age, gender, and smoking status. Telomerase activity was significantly lower in the lung cancer patients than in controls (mean +/- standard deviation; 1.32 +/- 1.65 vs 2.60 +/- 3.09, P < 1 x 10(-4)). When telomerase activity was categorized into quartiles based on telomerase activity in the controls, the risk of lung cancer increased as telomerase activity reduced (Ptrend = 1 x 10(-4)). Moreover, when the subjects were categorized based on the median value of telomerase activity, subjects with low telomerase activity were at a significantly increased risk of lung cancer compared to subjects with high telomerase activity (adjusted odds ratio = 3.05, 95% confidence interval = 1.60-5.82, P = 7 x 10-4). These findings suggest that telomerase activity may affect telomere maintenance, thereby contributing to susceptibility to lung cancer.
