Takayasu,s arteritis is a systemic disease characterized by occlusion of aorta and its major branches because of a panaortitis with thickening of the adventitia. Coronary artery narrowing is due to extension of inflammations that occur in aorta. Angina pectoris may be the first symptom of the disease if the coronary arteries are the initial site of severe arterial narrowing. We present a case of bilateral coronary ostial stenosis where Takayasu,s arteritis was pathologically proved as an etiology. The patient was taken coronary ostial angioplasty with good result.

BACKGROUND: Evaluation of clinical performance is an essential area for the students who are preparing their career as a medical doctor. However the clinical skills has neither been taught with balanced proportion nor adequately being assessed their abilities. Yet no significant studies on this issue has been reported in Korea so far. The present study was done as a part of preliminary study to seek a model that would be introduced clinical performance assessment in Korean Medical Licensure Examination system. Purpose: The objectives of this study is to develop items of clinical performance and the effective methods to carry out the clinical performance assessment in Korean Medical Licensure Examination system. METHODS: Primary list of clinical performances which was generated through discussion between researchers and medical experts has been distributed to the physicians of various levels. Six hundred ninety seven medical doctors including professors, family physicians, and public health doctors were asked to express their opinion by mail questionnaire. Final items were selected after the reaction of questionnaires and each item has been carefully studied its validity, achievability, and practicality. RESULTS: Thirty five items were selected among fifty one items presented according to the checked number of "essential" and "frequently useful". Seven items were added according to the higher rate of recommendation by open questionnaire. The forty two items were confirmed as a final list which the students should be expected to demonstrate prior to graduation from undergraduate medical school("exit objective"). The OSCE was performed without any serious logistic problems and both examinees and evaluators thought the experience positively. CONCLUSION: To look at the present environment and the readiness it is recommendable to apply the items of psychomotor skills at the beginning for Medical Licensure Examination. For that purpose various medical dolls, kits and subjects can be used.

We report a 26-yr-old female patient with bilateral breast cancer who was clinically diagnosed with Li-Fraumeni like syndrome (LFL) and subsequently found to have a germline mutation of the TP53 gene. The patient was initially diagnosed with right breast cancer at age 24 yr and then with left breast cancer at age 25 yr. Surgery and radiotherapy were performed accordingly. The patient had a family history of various types of early onset cancers and was referred to a genetic counseling clinic. She was clinically diagnosed with LFL. Genetic analysis of the TP53 tumor suppressor gene was performed with the patient's consent. Direct sequencing of TP53 gene exons 5, 6, 8, 9, and 11 revealed a ermline missense mutation, resulting in an amino acid change from an arginine to a histidine (g.13203G>A, p.R175H). Considering the family history, individualized cancer surveillance was performed including a gastroscopy and a brain MRI. Even though the patient had not shown any neurological symptoms, a huge mass on the temporal lobe was incidentally found and the patient received surgery and radiotherapy. Although the residual mass required further treatment, the patient decided on supportive care alone and was discharged. We report a case of LFL, with a germline TP53 mutation, which was confirmed by gene sequencing in Korea. This case shows how genetic predisposition screening and counseling in patients, suspected of having a familial cancer syndrome, can influence the course of the patient.

Cyclosporine nephropathy was induced by intraperitoneal injection of cyclosporine 25 mg/kg in Sprague-Dawley rats daily for 1, 4, 8, and 12 weeks to clarify the relationship between cyclosporine nephropathy and the expression of TGF-beta1 with extracellular matrix deposition. On light microscopic examination, the kidneys in the 12 week cyclosporine-treated rats showed focal or striped fibrosis, vacuolization of tubular cells, and injury of endothelial cells. Immunohistochemically, TGF-beta1 protein was strongly expressed in the cyclosporine-treated rat kidneys, especially in the glomerular endothelial cells, interstitial endothelial cells, tubular epithelial cells, and parietal cells in the Bowman's capsule of the glomerulus as well as the periglomerular arterioles. The amount of TGF-beta1 expression was correlated with the morphological change in the cyclosporine-treated rats. Extracellular matrix, such as fibronectin and collagen IV, was also expressed in the endothelial cells of the glomerulus and the interstitium. It can be concluded, therefore that TGF-beta1 protein is probably involved in the early stage of fibrogenesis in cyclosporine nephropathy. It can be postulated that cyclosporine nephropathy results from the accumulation of extracellular matrix associated with the increase of TGF-beta1 transcription. Therefore, these results could be used in reducing fibrosis in cyclosporine nephropathy.

Ninety two strains of Streptococcus pyogenes were isolated from patients with pharyngitis, scarlet fever, skin infection, and invasive streptococcal infections in Seoul, Korea from January to December, 1998. All isolates were epidemiologically characterized by T protein serotype, and serum opacity factor (OF) detection to phenotypes. To analyze the genetic relationship, fifty two isolates including 32 erythromycin-clindamycin (Em-Cm) resistant strains, 20 antimicrobial susceptible strains were attempted to the pulsed-field gel electrophoresis (PFGE). T protein serotype showed 16 kinds in distribution including T12 and T4. Among the total isolates, 40 strains (43.5%) belonged to the T12 serotype and twenty strains (21.7%) to T4 serotype. On the other hand, when infection aspect of S. pyogenes isolates were analysed by T serotype distribution, T12 type was predominant for pharyngitidis which contributed to 21 strains (53%) and for skin infection isolates which contributed to 11 strains (28%), respectively. In case of T4 type, it was the most predominant pharyngitidis isolates which contributed to 8 strains (40%). In T serotype distribution of Em-Cm resistant strains, 27 strains (84%) of the thirty two showed T12 serotype. In minimum inhibitory concentration (MIC) values of Em-Cm resistance isolates, thirty two isolates showed resistant to erythromycin 27 strains (84%), had high MIC of >128 mug/ml. And also to clindamycin, twenty two strains (69%) had high MIC of >128 mug/ml. When OF detection of Em-Cm resistance of S. pyogenes isolates were analyzed by T serotype distribution, T12 serotype isolates revealed that all of the isolates except one strain were OF negative. In PFGE profile analysis to Em-Cm resistance isolates, of the twenty seven, Em-Cm resistance of T12 serotype isolates, 26 strains showed identical PFGE profile and all of these isolates revealed that OF negative. Eighty four percent of Em-Cm resistance S. pyogenes isolates had identical phenotype and PFGE profile. These results strongly suggested that the Em-Cm resistant S. pyogenes isolates from Seoul area showed close genetic correlation and PFGE could be available tool for molecular epidemiology.

We analysed video tapes in 31 patients of 97 seizures who were evaluated for epilepsy surgery at AMC Neurology department between 1992 and 1994. All patients had epilepsy surgery such as temporal lobe resection or gamma knife radiosurgery. They were either seizure free or had a greater than 90% reduction in the number of seizures for at least 12 months following surgery. Oromandibular automatism (74.2%), behavioral arrest/staring (63.9%), and upper extremity automatisms (37 1%) were frequent ictal manifestations of mesial temporal lobe epilepsy in our patients, Initial non-versive head turning was observed in 49 events (ipsilateral 77.8%, contralateral 22.2%), while versive head turning was noticed in 25 events (ipsilateral 7.1%, contralateral 92.9%). Contralateral dystonic posture was observed in 47 events (48.5%). Vocalization was observed in 2 among 12 patients (16.7%) with non-dominant sided lesions, and 9 among 19 patients (47.4%) with dominant sided lesions. Dystonic posture was observed contralaterally (100%), hand automatism ipsilaterally (94.4%) and versive head/eye turning wart observed ipsilaterally (92.3%) in our patients. So we concluded that valuable lateralizing sign in mesial temporal lobe origin seizure are contralateral dystonic posture, ipsilateral hand automatism, and versive contralateral head/eye turning. And also turning and rounding sign may have possible lateralizing value.
