BACKGROUND: Vitiligo is riot quite a rare diseasep; it has about 1% prevalence. The cause of vitiligo is not clear, however, in recent studies an autoimmune origin is freqluei itily mentioned. OBJECT: We tried to an lyze some clinical features of vitiligo and relate them with the presence of autoantibodies. MEHTODS: A total of 381 vitiligo patients was included for the analysis of clinical features. A laboratory study included rhumatoid factor, antinuclear antibocoly, antithyroglobulin antibody and antimicrosome antibody. Some 62 patients were examined for opl thmologic changes. RESULTS: One hundred and one(26.5%) of 381 patients exam ned showed at least one of the autoantibodies tested. Twenty nine pateints showed 2 different aitintibodies. The age at aonset of vitiligo in the autoantibody positive group was 6.6 years later than that of the autoantibody negative group. Autoimmune and/or endocrine diseases were more frequinty found among aut.oantibody positive patients. These diseas s included hyperthyroidism, diabetes me litus and alopecia areata. One patient revealed retinal hypoigmentation and showed no autoantibcidics. CONCLUSION: About 9% of vitiligo patients who were autoantiocyte positive had clinical evidence of diseases associated with the autoantibody. However, it is prudent. to xpect that more patients with t.he autoantibody may develop later systemic autoimmune diseases or endocrinopathies. A long term follow-up of these patients seem:, to be very important.

Two cases of carcinoid tumor of the uterine cervix were reported with emphasis on the histologic, cytologic, histochemical and electron microscopic appearance of tumor cells. Based on the light microscopic findings, one case was a well differentiated carcinoid with acinus formation, and the other was a poorly differentiated anaplastic type, being composed of small cells similar to those of oat cell carcinoma of the lung. Both tumors demonstrated scattered argyrophilic cells on Grimelius stain, and contained neurosecretory granules on electron microscopy. They were in stages II b and IV, respectively, at the time of presentation. The latter patient was treated with vinblastin, platinol and bleomycin, but died in 9 months after the initial diagnosis. The former was lost to follow-up study. Importance of distinction between this highly malignant tumor and other varieties of cervical cancer was emphasized.

Many unsolved probIems still remain in these in management of trochanteric fracture of hip, especially unstable type of trochanteric fracture. Among many cases of the trochanteric fracture treated during period from Jan. 1963 to July, 1973 at Busan National University Hospital, six patient has severe sequelae such as coxa vara deformity, shortening of the affected limb and ankylosis of the hip joint, which were analyzed clinically and results obtained were as follow. 1. It is the most important factor that the medial and the posterior cortex is good alignment in reduction with internal fixation and maintainance of unstable trochanteric fracture. 2. It is dangerous for the unstable type of trochanteric fracture to be reducted and maintained with only screws or plates. Jewett nail is more effective than the S-P nail and Thornton plate in internal fixation of unstable type of trochanteric franture. 3. The posterior fragments can hardly be found in A-P view but easily in lateral view 4. In cases that had not good alignments between posterior fragments the distaI fragment displaced medially and migration of the naiI, distraction of the pIate, malunion have developed in spite of prolonged immobilization in cast. 5. In one case that the severe coxa vara deformity have been developed. we performed the transverse osteotomy & fixed with Blount-V-blade plate like device. The result was good but the shortening of the limb could not prevent.

Since the introduction of percutaneous mitral valvotomy(PMV) in 1984, PMV was an effecive alternative to surgical commissurotomy in selected patients with severe mitral stenosis. Also PMV was an excellent palliative strategy in such patients who were high risk for operative management or longterm anticoagulation was not feasible. We performed PMV in a patient with very tight mitral stenosis and severe pulmonary hypertension under the general anesthesia because the patient was anticipated to be uncooperative due to mental problem, who was diagnosed as schizophrenia 16 years ago. Robinol was used for premedication and i.v fentanyl was used for maintenance of anesthesia. Inoue balloon was introduced into the LV and gradual ballooning was performed with favorable results. Total anesthesia time and interval from internal jugular vein puncture to the completion of valvuloplasty were 1 hour 45 min and 40 minutes respectively. Hemodynamic variables were improved immediately after intervention and mitral valve area was increased from 0.5cm2 to 1.3cm2.

It has been studied that a variety of fauna and flora are sensitive biological indicators which reflect the severity of regional pollution of heavy metals, but in the center of part of Taegu city the controversial issue of lead poisoning attributable to the atmosphere which contains an increased concentrations of lead has been raised recently, it is usually hard to find suitable plants or animal in the areas with heavy traffic. Pigeons are ubiquitous in and around Taegu city area, inhabiting even the most densely populated areas with heavy traffic with its small body size, high metabolic turnover, and rather limited mobility, a pigeon, as a biological indicator is expected. This study was conducted to monitor lead pollution in the Taegu and kyongju city in Korea. We measured the lead content of the various tissue of three groups of feral pigeon(Columbia livia) and soil and atmospheric lead concentration. First group was obtained io heavy traffic area in Taegu City, the second group was obtained a park in Taegu city and the third group was obtained light traffic area in kyongju city. The air and soil lead concentration of heavy traffic area in Taegu city was 0.11 microgram/m2, 4.96 microgram/g, that of park in Taegu city was 0.05 microgram/m3, 2.65 microgram/g and that of light traffic area in kyonngju city was 0.03 microgram/m3, 0.01 microgram/g. The lead content of lung, blood, kidney, femur and liver of feral pigeons in heavy traffic area in Taegu city was significantly higher than pigeons obtained in a park in Taegu city and low traffic density area in Kyonfju city(p<0.01). But stomach lead content of three group did not reflect a significant difference. In this study positive correlation was found between atmospheric lead concentrations and the concentration of lead in the pigeon's lung(r=0.5040, p<0.001), blood(r=0.3322, p<0.01), kidney(r=0.4824, p<0.001), femur(r=0.7214, p<0.001) and liverer (r=0.4836, p<0.01). we can also found positive correlation between soil lead concentrations and the concentration of lead in the pigeon's femur(r=0.4850, p<0.001), kidney(r=0.4850, p<0.001) and liver(r=0.4386, p<0.01). In the pigeon`s tissue there were significant correlations between concentration of lead in the blood and kidney(r=0.4818, p<0.001), femur(r= 0.6157, p<0.001) and liver(r=0.3889, p<0.001). In conclusion, at the heavy traffic area in Taegu city, lead concentrations found in the atmosphere and soil are reflected in the lead concentrations of different tissue of urban pigeons. It is suggested that the tissue of pigeons can be good biological indicators of environmental lead pollution.

OBJECTIVES: The hospital standardized mortality ratio (HSMR) has been widely used because it allows for robust risk adjustment using administrative data and is important for improving the quality of patient care. METHODS: All inpatients discharged from hospitals with more than 700 beds (66 hospitals) in 2008 were eligible for inclusion. Using the claims data, 29 most responsible diagnosis (MRDx), accounting for 80% of all inpatient deaths among these hospitals, were identified, and inpatients with those MRDx were selected. The final study population included 703 571 inpatients including 27 718 (3.9% of all inpatients) in-hospital deaths. Using logistic regression, risk-adjusted models for predicting in-hospital mortality were created for each MRDx. The HSMR of individual hospitals was calculated for each MRDx using the model coefficients. The models included age, gender, income level, urgency of admission, diagnosis codes, disease-specific risk factors, and comorbidities. The Elixhauser comorbidity index was used to adjust for comorbidities. RESULTS: For 26 out of 29 MRDx, the c-statistics of these mortality prediction models were higher than 0.8 indicating excellent discriminative power. The HSMR greatly varied across hospitals and disease groups. The academic status of the hospital was the only factor significantly associated with the HSMR. CONCLUSIONS: We found a large variation in HSMR among hospitals; therefore, efforts to reduce these variations including continuous monitoring and regular disclosure of the HSMR are required.

Impaired endothelium dependent relaxation occurs in diabetic rabbit corpus cavernosum and normal corpus cavernosum exposed to elevated glucose. Elevation of glucose can change the activities of two key enzymes, protein kinase C (PKC) and Na+-K+ ATPase. This study addresses the question of whether impaired endothelium dependent relaxation in isolated corpus cavernosum from normal rabbit exposed to elevated glucose is related to PKC and Na+-K+ ATPase activities and, if so, whether it is associated with altered ouabain sensitive 86-Rb uptake, an index of Na+-K+ ATPase activity, and contractile response of corpus cavernosum tissue to ouabain. Corpus cavernosal tissue suspended for measurement of isometric tension were incubated for 6 hours in control (5.5mM) or elevated glucose (44mM) to mimic euglycemic and hyperglycemic conditions. Relaxations of corpus cavernosum tissue in response to the endothelium-dependent vasodilator acetylcholine (ACh)were unaffected in control groups while significantly inhibited in the elevated glucose group. Relaxations of corporeal tissue to endothelium-independent vasodilators, sodium nitroprusside (SNP) were similar in the control and elevated glucose groups. Corporeal tissue treated with 4-phorbol 12-myristate 13-acetate (PMA), a PKC activator, showed decreased relaxations to ACh, similar to normal corporeal tissue exposed to elevated glucose. Relaxations in response to SNP were unaffected by treatment with PMA or exposure to elevated glucose. 1(5-isoquinolinylsulfonyl)-2-methylpiperazine (H-7), PKC inhibitor, restored the abnormal Ach-induced relaxation in corporeal tissue exposed to elevated glucose. The contractions caused by ouabain, Na+-K+ ATPase inhibitor, were smaller in elevated glucose groups than control and elevated glucose groups treated with H-7. Ouabain sensitive 86-Rb uptake of elevated glucose groups was significantly less than that of control groups but ouabain sensitive 86-Rb uptake of elevated glucose groups treated with H-7 was similar to those of control groups. These results suggest that activation in PKC activity and inhibition in Na+-K+ ATPase activity caused by elevated glucose contribute to impaired endothelium dependent relaxation in corpus cavernosum smooth muscle.

This paper deals with a case of linear IgA bullous dermatosis (LABD). The patient was a 58-year-old woman who had multiple pruritic vesicles on the trunk, buttocks, thighs, tongue and buccal mucosa. A biopsy of a lesion revealed subepidermal vesicles. Direct immunofluorescence examination of the perilesional skin showed a linear deposition of IgA along the basement membrane zone (BMZ). Indirect immunofluorescence examination, using NaCl split skin as substrate, showed antiBMZ IgA antibodies bound only to the epidermal side. The skin lesions responded well to oral dapsone therapy.
