Primitive neuroectodermal tumors (PNET) of the ovary are rare tumors with an exclusive or almost exclusive malignant neuroectodermal composition, and are generally regarded as a monodermal expression of an ovarian teratoma. The tumors are basically identical with the lesions of the same name occuring typically in the central nervous system of children. These tumors consist chiefly of undifferentiated small cells resembling neuroblasts. There are also mature, well- differentiated neuroectodermal cells, such as astrocytes and ependymal cells. We report a case of ovarian PNET with glial and neuroblastic differentiation and focal teratomatous foci of non-neural tissue in a 17-year-old female.

BACKGROUND: The goal of antihypertensive therapy will be to extended the life expectancy of hypertensive patients to that of subjects without high blood pressure. Hypertension treatment in the 1990s will focus on the mechanisms by which blood pressure is lowered by various antihypertensive agents, as will as individualization of drug therapy. In recognition of their lack of adverse lipid effects and their tolerability, first line therapy with alpha blocker, angiotensin converting enzyme inhibitors and calcium antagonists will become increasingly commom. We studied a new dihydropyridine calcium antagonist barnidipine to evaluate the efficacy and safety in patients with essential hypertension. METHODS: The rabit aortic rings were cut and mounted on the force transducer to record an isometric tension on polygraph. To elucidate the mechanism of saponin effect on vascular smooth muscle, the contractility of the vascular smooth muscle were measured under vatying experimental condition. RESULTS: 1) The baseline sitting systolic and diastolic blood pressure after 4 weeks washout period were 154.+/-15.9mmHg and 1.0+/-8.2mmHg. At the end of 8 weeks of therapy sitting systolic and diastolic blood pressure were 126+/-9.5mmHg and 84.5+/-4.6mmHg which declined statistically significant(p<0.05). 2) The pulse rates did not change significantly during treatment period(70.0+/-6.6 beats / min at baseline, 70.9+/-7.2 beats / min at 2 weeks, 71.2+/-5.0 beats / min at 4 weeks, 72.8+/-8.5 beats / min at 6 weeks, and 71.9+/-6.8 beats / min). 3) The adverse reactions due to branidipine were reported in 2 patients(6.5%) with headache, 2 patients(6.5%) with facial flushing, 1 patient(3.4%) with dizziness and 1 patients(3.4%) with nausea and vomiting). 4) The abnormal laboratory findings due to barnidipine were reported in 1 patient with increased total bilirubin and GPT, 1 patient with increased transaminase and 1 patient with CK but another findings were normal. CONCLUSION: These results indicate that barnidipine is effective and safe antihypertensive agent in the treatment of essential hypertension.

To evaluate the effect of Perindopril in patients with essential hypertension, we administered Perindopril 4 to 8mg/day once daily to 30 patients(18 males, 12 females) for 12 weeks. Baseline blood pressure after 4 weeks with placebo was 150.4+/-7.5/102.0+/-4.3mmHg. The blood pressures of the patients were declined significantly at 4th(140.6+/-14.9/95.4+/-6.5), 8th(136.7+/-11.4/91.7+/-7.6), and 12th(132.3+/-11.1/87.5+/-6.9) week(p<0.01) without change of heart rate. The blood pressure of the patients was normalized below 140/30mmHg in 24 patients(80%) and declined diastolic blood pressure more than 10mmHg in one patients. Therefore the response rate of perindopril was 83.3%. There were reported 3 patients who revealed mild adverse reactions as follows; cough, indigestion, dizziness in one each. In conclusion, these results indicate that antihypertensive therapy with perindopril single daily dose was effective in patients with mild to moderate essential hypertension and well tolerated.

BACKGROUND: Several antibiotics can be used to treat ventilator-associated pneumonia caused by carbapenem-resistant A. baumannii (CRAB-VAP) including high-dose sulbactam. However, the effectiveness of high-dose sulbactam therapy is not well known. We report our experience with high-dose sulbactam for treatment of CRAB-VAP. METHODS: Medical records of patients with CRAB-VAP who were given high-dose sulbactam between May 2013 and June 2015 were reviewed. RESULTS: Fifty-eight patients with CRAB-VAP were treated with high-dose sulbactam. The mean age was 72.0 ± 15.2 years, and the acute physiology and chronic health evaluation II (APACHE II) score was 15.1 ± 5.10 at the time of CRAB-VAP diagnosis. Early clinical improvement was observed in 65.5% of patients, and 30-day mortality was 29.3%. Early clinical failure (odds ratio [OR]: 8.720, confidence interval [CI]: 1.346-56.484; p = 0.023) and APACHE II score ≥ 14 at CRAB-VAP diagnosis (OR: 10.934, CI: 1.047-114.148; p = 0.046) were associated with 30-day mortality. CONCLUSIONS: High-dose sulbactam therapy may be effective for the treatment of CRAB-VAP. However, early clinical failure was observed in 35% of patients and was associated with poor outcome.

Congenital lipoid adrenal hyperplasia, the most severe form of congenital adrenal hyperplasia, is caused by mutations in the steroidogenic acute regulatory protien (StAR). It is characterized by failure of synthesis of all three classes of adrenal steroids and massive accumulation of lipids and cholesterol in the adrenal cortex. The computed tomography (CT) unequivocally delineated massively enlarged adrenal glands of fat-tissue attenuation, enabling early diagnosis and replacement therapy. We report a case of congenital lipoid adrenal hyperplasia, in which CT established that lipoid deposition at the adrenal cortex disappeared after the adrenal hormone replacement therapy.

BACKGROUND: Hyperlipidemia is the one of the major risk factors causing the atherosclerosis of coronary arteries. Treatment of hyperlipidemia with drugs has been confirmed the effects of therapy showing a decreased incidence of coronary artery disease. Pravastatin is one of the new HMG-CoA reductase inhibitors and we studied the short-term hypolipidemic effects and safety of pravastatin in patients with hyperlipidemia. METHODS: We studied 31 patients(7 males and 24 females ; range of age, 36-67 years) for 12 weeks whose plasma levels of total cholesterol were higher than 250mg% after one month period of diet therapy. Pravastatin was administered 10mg/day and measured lipid profiles at 4 week interval. RESULTS: Pravastatin reduced the plasma total cholesterol from 286.2mg% to 212.3mg% (25.9%), the LDL-cholesterol from 204.2mg% to 143.6mg% (29.7%), the triglyceride from 226.0mg% to 161.4mg% (28.6%) after 12 weeks treatment. The HDL-cholesterol increased from 25.8mg% to 46.4mg% (20.5%) after pravastatin therapy. These changes were disclosed all statistically significant compared to baseline levels(p<0.01). The clinical and laboratory examinations before and after pravastatin treatment showed no particular abnormal findings. CONCLUSIONS: These results suggested that short-term pravastatin therapy in patients with hyperlipidemia seems to be very effective and safe.

BACKGROUND: Mycosis fungoides(MF) is a form of cutaneous T cell lymphoma with clonal differentiation of helpr' T cell. It has a patch, plaque, and tumor stage. But pathogenetic factors controlling the development and progression of MF are still unclear. Apoptosis plays a major role in developmental biology and homeostasis. The bcl-2 oncogene prolongs ce11 life by inhibiting apoptosis. The mutant pS3 gene induces apoptosis indirectly. Ki-67 antigen is the cell proliferation marker. Recently, it has been shown that the relationships among them are important in the tumorigenesis of the various tumors. OBJECTIVE: The aim of this study was to examine the expression of these genes and apoptotic rate and clarify the relationship among them in the development and progression of MF. METHODS: The eighteen specimens from 8 patients with MF and 10 specimens from benign lymphocytic infiltrating diseases including 5 lichen planus, 3 lupus erythematosus, and 2 contact dermatitis were included. We performed immunoperoxidase staining(LSAB technique) using monoclonal antibodies including bc1-2, p~53, and Ki-67(MIB1). We used ApoptaqTM(Oncor) in situ labelling kit for detecting apoptotic cell.

Necrolytic migratory erythema is a rare, distinctive, necrotizing cutaneous eruption usually associated with glucagonoma, an alpha-cell tumor of the pancreas. Other clinical features include ane- mia, diabetes mellitus and weight loss. However, it also occurrs without the pancreatic glucagonoma. So this rare condition is called pseudoglucagonoma syndrome, and has been described in association with chronic hepatic diseases, malabsorption with villous atrophy, chronic pancreatitis, celiac sprue, hypoproteinemia and odontogenic infection. We report a case of pseudoglucagonoma syndrome induced by malnutrition without glucagonoma. A 28-year-old Korean female was referred to our department complaining of multiple erythematous, desquamative, crusted and erosive patches on the extremities, and diffuse scalp alopecia for 5 years. She also had perianal erosion, angular cheilitis without glossitis, amenorrhea, axillary and pubic hair loss, and weight loss. Six years previously she had had Whipples operation for a pancreatic solid and papillary neoplasm. The laboratory data showed hypoalbuminemia, essential fatty acid deficiency, diabetes mellitus and slightly high levels of zinc and glucagon. A skin biopsy showed irregular acanthosis, epidermal edema and pallor, dyskeratosis, areas of superficial epidermal necrosis and vascular dilatation of the papillary dermis. The patient improved dramatically after intravenous hyperalimentation and oral intake of mediurn chain triglyceride. For 2.5 years she has taken medium-chain triglycerides without any other treatment, and no side effects on recurrence has been observed.
