PURPOSE: Racemose hemangiomas of the retina are rare developmental vascular anomalies with abnormal arteriovenous anastomoses. We report our observations of a retinal racemose hemangioma with marked dilation and tortuosity of the retinal vessels in the entire left retina. METHODS: In a 9-year-old boy with loss of vision and mild esotropia who presented with hugely dilated and tortuous retinal vessels in left retina, we examined fundus, fluorescein angiography, cerebral angiography, brain CT and MRI. RESULTS: Fundus and fluorescein angiography of the left eye showed marked dilation and tortuosity of the retinal vessels. Angiographic finding showed rapid filling of all vessels and no dye leakage. MRI finding revealed small tortuous vessels around left optic nerve, optic chiasm and tract. Brain CT and cerebral angiography showed nothing abnormal.

Blunt thorax trauma may produce a variety of cardiac lesions, which may occur alone or in combination. Nonpenetrating perforation of interventricular septum with chordae rupture of tricuspid valve is a infrequent pathologic event. A 40-years-old worker was transfered to hospital with increasing symptoms of right heart failure following a blunt compressing chest trauma with a huge overolling cement pipe(Wt.680kg) 6 weeks ago. The immediately diagnosed serial rib fracture of the left thorax cage and dislocation of the left acromoclavicular joint were treat conservatively. A conventional transthoracic color Doppler and two dimensional echocardiogram detected traumatic ventricular septal defect with bilatral shunt and tricuspid regurgitation. An additional transesophageal color echocardiopraphic demonstrated the ruptured chordae tendineae of the tricuspid septal leafet, which prolapsed deeply into the right atrium. The conventional color Doppler echocardiopraphy enhances the ability to detect the presence of a ventricular septal perforation and valve dysfunction in a patient with cardiac contusion. The transesophageal echocardiopraphy is a useful semiinvasive tool for the detailed morphological evaluation of atrioventricular valves and their substructure.

Adenocarcinoma of the bladder is rare. During the last 20 years 13 patients with adenocarcinoma of the bladder were managed at Seoul National University Hospital. The incidence is 2.2% of all primary epithelial bladder neoplams. 10 patients had primary adenocarcinoma and urachal origins were identified in 3 patients. The most common presentation was painless gross hematuria. 9 of 10 patients with primary adenocarcinoma had deeply infiltrating tumor with or without distant metastasis at the time of initial diagnosis. Various interventions including TUR and partial cystectomy were carried out. In 5 patients postoperative radiation therapy was tried without substantial improvement. Three year survival rate of primary adenocarcinoma had was averaged less than 25% regardless of the mode of treatment. One patient was free of cancer up to 3 years. 3 patients with urachal adenocarcinoma had stage D of mucin producing adenocarcinoma. Partial cystectomy including enbloc excision of urachus in 1 was carried out, partial cystectomy in 1 and exploration for unresectable tumor in one patient who died in one year.

It has long been known that smoking can have a deleterious effect on sexual potency and fertility capacity of males but the subject of the possible adverse effects of cigarette smoking on steroidogenesis and spermatogenesis is controversial. The comparative study presented here was conducted on 30 cigarette-smokers and 30 non-cigarette-smokers of men. They were divided into 3 different groups such as control group (composed of 10 smokers and 10 non-smokers), impotence group (10 smokers and 10 non-smokers) and infertility group (10 smokers and 10 non-smokers). They were subjected to the investigation of medical history, body weight, height, testicular size, coital frequency per week, nocturnal penile tumescence frequency per week, routine laboratory works, plasma FSH, LH, testosterone and prolactin by radioimmunossay and semen analyses. The smokers were found to have a slightly smmaller frequency of coitus per week and also that of nocturnal penile tumescence per week than non-smokers but the differences were not significant. Plasma FSH, LH, testosterone and prolactin levels were also hot significantly different between smokers and non-smokers of each group. The levels of LH and testosterone of control group were greater than thoses of impotence and infertility groups. Semen samples from control and impotence groups showed no significant differences on volume, count, motility and morphology between smokers and non-smokers. Only in the infertility group, sperm motility was significantly greater in non-smokers than smokers and also morphology was slightly greater in non-smokers than smokers but the difference was not significant. The results of this study identify that the postulated deteriolated effect of cigarette smoking on steroidogenesis and spermatogenesis would have most significantly impinged. However, its clarification will require more careful and extensive investigations with large groups of subjects.

Testicular carcinoid tumor is uncommon and most of these tumors occur in fourth decade' of life. A 33-year-old man presented with intrascrotal painless mass, which was initially misdiagnosed as epididymal tumor. Epididymectomy including the mass was performed and pathologic examination revealed a carcinoid tumor confined to the rete testis. There was no evidence of carcinoid syndrome. The 24 hour urinary 5-HIAA level was normal. Abdominal CT scan and GI contrast study showed no evidence of carcinoid in other organ including the gut. Radical orchiectomy and hemiscrotectomy were undergone as a curative therapy. He has been well for 40 months without recurrence.
