BACKGROUND: In order to evaluate the prevalence of enterovirus and cytomegalovirus infections to terminally failing hearts, the presence of enteroviral RNA and cytomegaloviral DNA was screened in the explanted hearts of transplantation recipients. METHODS: RNA and DNA extractions were performed from explanted failing hearts (N=22) and normal hearts (N=5). Reverse transcription-polymerase chain reaction (RT-PCR) of enterovirus and polymerase chain reaction (PCR) of cytomegalovirus were performed. In situ RT-PCR and in situ PCR were performed with positive nucleic acids of viruses. RESULTS: The positivity of enterovirus in failing hearts was 4.4% (1/22) and 0% (0/5) in normal hearts in nested RT-PCR. There was no significant difference in positivity of enteroviral RNA between failing and normal hearts. Nuclei of myocardium was stained in dark-violet color with in situ RT-PCR. The positivity of cytomegalovirus in failing hearts was 45% (10/22) and 40% (2/5) in nested PCR. There was no significant difference in positivity of cytomegaloviral DNA between failing and normal hearts. Nuclei of myocardium was stained in dark-violet color with in situ PCR. Positive chambers of cytomegalovirus were in decreasing tendency according to increasing patient's age. CONCLUSION: Enterovirus was very rarely observed in explanted terminally failing hearts and cytomegalovirus was frequently found both in explanted failing hearts and normal. These viruses have little direct causal relationship with the development of heart failure.

Arytenoid subluxation or recurrent laryngeal nerve paralysis may result from injury to the larynx following endotracheal intubation or blunt laryngeal trauma. Early diagnosis is important for appropriate treatment and better prognosis. A 62-years-old man was admitted for cholecystectomy. He was intubated without any difficulty and nasogastric tube was inserted with the help of laryngoscope and Magill forcep before surgery. He had a weak voice and hoarseness after atraumatic extubation and those symptoms did not improve even 2 days after. Indirect laryngoscopy, videolaryngotelescopy, electromyography(EMG) and computed tomographic findings revealed anterior, inferior subluxation of left cricoarytenoid cartilage associated with left thyroarytenoid muscle denervation and resultant unilateral vocal cord palsy. Conservative treatment for 40 days after the operation and follow-up examination was done. The voice quality was improved and indirect laryngoscopy examination showed that right vocal cord crossed midline in a attempt to meet its paralyzed counterpart on phonation.

Bacteroides fragilis is a Gram negative nonsporulating anaerobic rod bacterium that makes up about 1 to 2% of the norrnal human colonic microflora. In 1984, Myer et al. reported that some strains of B. fragilis produce enterotoxin and cause diarrheal disease in cattle and human. Since then it has been termed enterotoxigenic B. fragilis (ETBF). In this study, we tried to detect enterotoxin gene from 37 B. fragilis strains, isolated in Korean patients, to confirm the existence of ETBF and usefulness of PCR as a rapid diagnosis method. By this method, we identified 9 ETBF strains and confirmed their pathogenesis by cytotoxicity test. No significant cross- reactivity with other anaerobes or aerobes was observed. Thus, the PCR method may be considered useful for the sensitive and rapid detection of anaerobic infections. And the entire amplified PCR mixture was ligated into a pT7Blue T-vector and transformed into E. coli. When the nucleotide sequences of cloned PCR products were compared with reported enterotoxin gene, pBF529 inserted DNA sequence was nearly in good agreement with it but pBF570 inserted DNA sequence showed some difference at nucleotide 270-300. A search for nucleotide sequence homologies revealed that pBF529 exhibited 99%, but pBF570 indicated only 90% identity with reported enterotoxin gene. According to these results, it was suggested that ETBF toxin can be differentiated into at least 2 subtypes.

From January 1979 to December 1983, eighty-five patients who had forearm bone fracture were treated by four different methods at the Department of Orthopedic Surgery, Chosun University Hospital. The results were as follows: 1. Among 85 patients, 12 patients were radius fractures, 19 patients were ulna fractures, 54 patients were both forearm bone fractures. 2. Closed fractures were 70 patients and the open fractures were 15 patients. 3. The mst common fracture site was middle third of the both radius and ulna. 4. The treatments were closed reduction with cast immobilization, intramedullary nailing or plate and screw fixation. 5. The time required for radiological bone union were shorter in compression plate fixation gmup, than those treated with other fixation device. 6. Functional result was claasified according to the rating system of Smith and Sage. The open reduction and internal fixation group had better results than the conservatively treated group.

Intrameduallary spinal hemangioblastoma is frequently associated with syringomyelia. It grows slowly and can be removed totally. Syringomyelia can be subcided by total removal of tumor and opening of syringomyelia. Two cases of intramedullary spinal hemangioblastomas associated with syringomyelia are reported. Intramedullary tumor and syrinx was easily diagnosed by magnetic resonance imaging(MRI). They are successfully managed by total removal of tumor and opening of syrinx. Patients showed improved neurological status after operations.

PURPOSE: To adapt to rapid and turbulent changes in the field of medicine, education, and society, medical school faculties need appropriate leadership. To develop leadership competencies through education, coaching, and mentoring, we need a leadership competency model. The purpose of this study was to develop a new leadership competency model that is suitable for medical school faculties in Korea. METHODS: To collect behavioral episodes with regard to leadership, we interviewed 54 subjects (faculties, residents, nurses) and surveyed 41 faculties with open-ended questionnaires. We classified the behavioral episodes based on Quinn and Cameron's leadership competency model and developed a Likert scale questionnaire to perform a confirmatory factor analysis. Two hundred seven medical school faculties responded to the questionnaire. RESULTS: The competency clusters that were identified by factor analysis were professionalism, citizenship, leadership, and membership to an organization. Accordingly, each cluster was linked with a dimension: self, society, team (that he/she is leading), and organization (to which he/she belongs). The clusters of competencies were: professional ability, ethics/morality, self-management, self-development, and passion; public interest, networking, social participation, and active service; motivating, caring, promoting teamwork, nurturing, conflict management, directing, performance management, and systems thinking; organizational orientation, collaboration, voluntary participation, and cost-benefit orientation. CONCLUSION: This competency model that fits medical school faculties in Korea can be used to design and develop selection plans, education programs, feedback tools, diagnostic evaluation tools, and career plan support programs.
