Brenner tumors constitute about l.5~2.5% of all primary ovarian neoplasms and are almost always benign. It appears to derive from the surface epithelium of the ovary which undergoes metap1asia to form the urothelial-like components. we experienced a case of malignant Brenner tumor with adenocarcinoma and squamous cell carcinoma patterns in a 57-year-old woman. It was partly cystic tumor and contained a 4cm-sized gray yellow, lobulated or papillary solid mass, projecting from the cystic wall. Ultrastructurally, the solid mass was composed of malignant urothelial-like cells with focal glandular differentiation.

We report a case of angiosarcoma of the jejunum in a 65-year-old female. This angiosarcoma developed 20 years after postoperative irradiation for cervical carcinoma of the uterus. Grossly, the resected jejunum showed a 8 cm long segmental hemorrhagic lesion with multiple, small hemorrhagic nodules or cysts on its serosa and mesentery. Microscopically, the wall of jejunum was infiltrated by epithelioid or polygonal tumor cells arranged in solid nests or lining irregular vascular spaces. The case is of interest that the tumor occurred in the very unusal site for angiosarcoma and the patient had a past history of irradiation for uterine cervical carcinoma 20 years ago. In addition, the resected intestine showed histologic changes of chronic irradiation effect. Therefore, this case supports the view that there is cause and effect relationship between irradiation adn angiosarcoma.

BACKGROUND: Cleaning and disinfection of fiberoptic bronchoscope requires careful attention, especially to mycobacterium species because the contamination of mycobacteria could raise confusion on diagnosis. Recently, we detected contamination of Wydex(R) solution used in bronchoscope washer with Mycobacterium chelonae. In this study, we evaluated the mycobactericidal effect of 12 kinds of disinfectants for M. chelonae. METHOD: To evaluate the bactericidal effect of Wydex(R) 2%, Cidex(R) 2.25%, Cidex(R) 3%, Bacteriokiller (BK) disinfectant, Perasafe(R), HICLO-S(R), Lamicine(R), ethanol, Instrusept(R), Virkon(R), Betadine(R), and Vipon(R) against M. chelonae, culture was performed after exposure of two M. chelonae strains (ATCC 35749, the type strain and the strain isolated from contaminated Wydex(R) solution) to each disinfectant solution. The growth of organism was examined for up to 8 weeks. RESULTS: Growth of M. chelonae (reference strain of ATCC 35749 and isolated strain) was observed after a week incubation for Wydex(R) 2%, Cidex(R) (2.25%, 3%) and control. For BK disinfectant and Perasafe(R), they grew after 2-3 weeks, and 3-4 weeks, respectively. For HICLO-S(R) and Lamicine(R), only the contaminated strain grew after two and three weeks, respectively. For ethanol, Virkon(R), Betadine(R), Vipon(R), and Instrusept(R) , growth was not observed from either strain. CONCLUSIONS: On the basis of these results, Instrusept(R), virkon(R), ethanol, Betadine(R), and Vipon(R) were effective for the disinfection of M. chelonae. Especially, Instrusept(R) was thought to be useful as a disinfectant for bronchoscopes because it has advantages including non-corrosiveness, chemical stability, and non-irritativeness. And additional washing with ethanol might be effective. The finding that strain isolated from contaminated bronchoscopes was more resistant to disinfectants than reference strain suggested that the more resistant strains are selected throughout the improper disinfection.

PURPOSE: A number of studies have been published on the effect of growth hormone therapy over 1-3 years in children with growth hormone deficiency(GHD) & Familial short stature(FSS). So far final height data are seldomly available. Final heights of GH treated children with GHD & FSS were evaluated. METHODS: 10 Children with GHD and 69 children with with FSS were enrolled for the study. They were treated with GH 0.1IU/kg/daily in 10 GHD and 20 children with FSS. They were grown up and reached adult height. 49 children with FSS were not treated at all. Facors influencing final height were investigated. RESULTS: 1) All patients with GHD(Idiopathic 8 cases, Organic 2 cases) had additional gonadotropin deficiency and had multiple pituitary hormone deficiency. 2) At start of GH treatment boys of idiopathic GHD were 9.8 years old and 12.4 years old in girls and their mean height was 114.8cm(-2.8SDS), 123.0cm(-2.9 SDS)in boys and girls respectively. Boy with orgnaic GHD was 11.1 years and 6.7 years old in girl. Their height were 126.0cm(-1.5SDS) and 104cm(-1.2SDS) respectively. 3) Mean final height of idiopathic GHD was 167.6cm(-0.5SDS) in male and 161.0 cm(0.7SDS) and that of organic GHD was 173.0cm(0.5SDS) in male and 157cm (0SDS) in girl. 4) Mean Final height in untreated children with FSS was 159.8+/-.2cm(-1.6 SDS)in male and 149.6+/-.3cm(-1.4SDS) in female. Mean final height of GH treated in FSS was 162.5+/-.1cm(-1.5SDS) in male and 152.0+/-.4cm(-1.2SDS) in female But there was no statiscally difference between untreated and treated children in final height. 5) The age of onset of menarche was 12.74+/-.78 years old in GH treated group (n=12) and 12.45+/-.16 years old in untreated group(n=34). CONCLUSION: The GH administration in patients with GHD has been confirmed for growth promotion. but in case of FSS there was no significant difference between treated and untreated group. More further studies are needed for the confirmation of the efficacy of GH therapy in patients with FSS.

PURPOSE: To evaluate the clinical efficacy of balloon catheter dilatation in the treatment of esophageal achalasia. MATERIALS AND METHODS: Seven patients(three males and four females) with esopha-geal achalasia were treated with balloon catheter dilatation. Balloon catheters of variable sizes were used depending on patient's conditions. The patients were followed up over a period of 12-39months. RESULTS: Balloon catheter dilatation in esophageal achalasia was successful in all patients without esophageal perforation. All patients were relieved from dysphagia. Recurrence was not found in 5 patients on long term follow-up study, but was seen in 2 patients after 18 and 21 months, respectively. CONCLUSION: Balloon catheter dilatation was a safe and effective method in the treatment of esophageal achalasia with low recurrence rate of 29% on follow-up study.

Well differentiated osteosarcomas are variants of osteosarcoma composed mainly of fibrous and osseous tissue with minimal cystologic atypia. This tumor may be misinterpretated as a benign lesion if the radiologic and clinical features are not taken into account. We report a typical case of intraosseous well differentiated osteosarcoma occuring in the left distal femur of a 58-year-old woman. Radiologically, it appered as an ill-defined lesion with a mixture of sclerotic and osteolytic ares. But there was a lack of highly destructive appearance of conventional osteosarcoma. Grossly, the mass occupied a metaphysis of the distal femur with extension into the diaphysis and epiphysis. Multifocal cortical destruction and sclerosis were also associated. Histologically, the mass showed typical features of intraosseous well differentiated osteosarcoma. There were various patterns of osteoid deposits and bone formation mimicking those of fibrous dysplasia, nonossifying fibroma or parosteal osteosarcoma.

Benign ductal or glandular neoplasms of the esophagus unrelated to Barrett esophagus are extremely rare. Only 9 cases have been reported in the English language literature. We now report a case of esophageal gland duct adenoma incidentally found in a 73-year-old man. A 0.8 cm-sized, polypoid submucosal lesion in the distal esophagus was removed. Histologically, the lesion was well circumscribed and consisted of several ducts or cysts with focal papillary configurations. Interstitial lymphocytic infiltration with germinal centers was also observed. The lining cells of ducts or cysts were composed of two layers: an inner intensely eosinophilic luminal duct cell layer and an outer myoepithelial cell layer that was accentuated by alpha-smooth muscle actin. There was no significant nuclear atypia or mitosis. Mucin production was occasionally observed in a few goblet cells. To the best of our knowledge, this is the first case of benign ductal or glandular neoplasm of the esophagus among Koreans.

PURPOSE:Urine examination for microalbuminuria during the clinical silent years can help to identify those patients most likely to progress to overt nephropathy. The normalization of the AER(Albumin Excretion Rate) by alteration of glomerular hemodynamics may be the key to preventing or delaying overt nephropathy. The prognostic and therapeutic implications have led to attempts to identify patients with microalbuminuria as early as possible.Because diagnosis of microalbuminuria has required a 12 or 24 hour urine collection,there has been interested in developing tests that might serve as a first-stage screen for microalbuminuria. Most reports have dealt with the usefulness of either the albumin concentration or the albumin/creatinine ratio in a timed or randomly collected urine specimen. Exercise induced albumin excretion is increased compared to resting and could unmask latent glomerular damage. The purpose of this study is to evaluate diagostic significance of urinary albumin measurement after exercise in children with insulin dependent diabetes. METHODS:Fifty-seven patients with IDDM collected their overnight urine from 22:00 to 6:00 in following morning. Exercised method for urine examination was 100M running and collected 2 hour urine after exercise. The AER and Albumin/ creatinine ratio(ACR) were measured in the urine and compared with before and after exercise. RESULTS:Mean ages of diabetic children was 13.7 yrs old and duration of diabetes was 4.1+/-2.7yrs, HbA1c 8.6+/-1.9%,Systolic BP 107+/-10mmHg and Diastolic BP 67+/-8mmHg. The exercise induced AER was increased compared to before exercise(10.3+/-10.5 vs 18.1+/-16.0 mg/24hr). The exercise induced ACR also increased too(1.4+/-1.5 mg/g.Cr vs 4.1+/-3.6mg/g.Cr)(P<0.01). Two(3.5%) children with IDDM was positive for microalbuminuria in terms of AER before exercise and 8 children(14%) after exercise. No one positive for microalbuminuria in terms of Alb/cr before and after exercise. The charateristics of 8 children with microalbuminuria after exercise was no specific difference between positive and negative microalbuminuria. There was specific correlation between microalbuminuria and HbA1c(P<0.05) but sex, ages, duration of diabetes & blood pressure were not correlated with incidence of microalbuminuria. CONCLUSION: The mean timed urinary albumin excretion after exercise was significantly higher than before exercise. Measurement of timed urinary albumin excretion after exercise will be helpful for detecting microalbuminuria earlier.

This study was performed to determine the health and nutritional risk factors associated with hypertension in Koreans over the age of 50 in a high-income class (more than twice as much family income as the 2005 Korean minimum cost of living, 668,540 Won). A total of 505 subjects aged over 50 from the 2005 Korean National Health and Nutrition Examination Survey (KNHANES) were divided into two groups: A hypertension group (HG) (N=151, Systolic Blood Pressure > or = 140 mmHg or Diastolic Blood Pressure > or = 90 mmHg) and normal group (NG) (N=354). Subjects who took hypertension medicines or underwent diet therapy were excluded. In HG, mean daily alcohol intake and the amount of alcohol consumption per one occasion were significantly higher than in NG, respectively. A greater number of hypertension subjects answered that they drank alcohol to reduce stress as compared to normal subjects. HG also took fewer dietary supplements than NG. Mean body mass index (BMI), waist circumference, fasting blood sugar level, and 2 hour postprandial blood sugar following a glucose load were significantly higher in HG than in NG, respectively. Also, iron, thiamin, and niacin intakes and the consumption frequency of seaweeds were significantly lower in HG than in NG, respectively. Finally, obesity (BMI > or = 25 kg/m2), abdominal obesity (waist circumference > or = 90 cm for males, > or = 80 cm for females), high blood sugar level 2 hours after an oral glucose load (> or = 140~200 mg/dl), and hypertriglyceridemia (serum TG > or = 200 mg/dl) were related to a significantly higher risk of hypertension in the subjects (odds ratio: 1.884~3.040). In conclusion, dietary factors such as higher alcohol consumption; lower intakes of iron, thiamin, and niacin; lower consumption frequency of seaweeds; and metabolic syndrome were associated with hypertension in the study subjects.
