Korean Journal of Physical Anthropology 1989;2(2):123-134
Patterns of branches and distribution of right coronary artery in Korean adult hearts were observed at the viewpoint of newly edited Nomina Anatomica, and the results were as follows. Generally the right aortic sinus had one orifice, but sometimes had two orifices which were related to conal branch. The right coronary artery had mural coronary in 17.5% of cases. In the most of the cases, right coronary artery was dominent, and type 4 was most frequent. Descending septal artery was observed in 17.5% of cases. The atrial branches can be grouped as anterior, posterior and left atrial, and each group was composed of one or two branches when present. In 97.5% of cases, intermediate atrial branch was observed. The sinuatrial nodal artery was originated mostly from right coronary artery. The atrioventriclar branch was observed in 7.5% of cases. The ventricular branches can be grouped as right anterior, right posterior and left posterior, and composed of 3-6, 0-2, and 0-4 branches respectively. Right marginal branch showed great variation, and other branch originated from superiorto to it was found to distribute the apex of the heart. Based on the results, the authors depicts typical arrangement of the rignt coronary artery in Korean.

The tricuspid valve is not a simple but a complex structure, tricuspid valve complex. This complex is composed of tricuspid orifice, annulus, valve leaflet, chordae tendineae and papillary muscles. There are flew articles about these structures. The authors studied tricuspid valve complex in 53 cases of normal korean adults, such as circumference of tricuspid annulus, the maximum diameter of the tricuspid orifice, height and breadth of the cusps, including commissures, the ratio of rough to clear zone, the number of scallops of posterior cusp, the number, length and pattern of arrangement of the several types of chordae, the number and morphological characteristics of papillary muscles.

A 46-year-old male patient developed jaundice after 23 days' treatment of propylthiouracil (PTU) for Graves' disease. Serum alkaline phosphatase was elevated markedly with moderate increase in serum aminotransferase, and the peak level of total bilirubin was 7.3 mg/dL. After withdrawal of PTU, serum aminotransferase and bilirubin began to decrease simultaneously, and completely normalized. One week after the discharge from hospital, he received radioiodine treatment for Graves' disease, but he showed aggravation of hyperthyroidism and ophthalmopathy. So we prescribed methimazole inevitably 16 days' after the radiodiodine treatment. He developed jaundice again after 69 days' treatment of methimazole, but the pattern of hepatotoxicity was slightly different from that of the previous PTU-nduced hepatotoxicity. Serum aminotransferase increased slightly and quickly normalized after discontinuance of methimazole, but serum total bilirubin increased continuously and reached to 24.6 mg/dL. Eosinophilia was prominent and the result of liver biopsy was compatible with cholestatic jaundice. The patient was treated with prednisolone and recovered from jaundice rapidly.

BACKGROUND: Surgery may have a role when medical treatment alone is not successful in patients with multi-drug resistant (MDR) pulmonary tuberculosis (PTB). To document the role of resection in MDR PTB, we analyzed 4 years of our experience. METHODS: A retrospective review was performed on thirteen patients that underwent pulmonary resection for MDR PTB between May 1996 and February 2000. All patients had organisms resistant to many of the first-line drugs including isoniazid (INH) and rifampicin (RFP). RESULTS: The thirteen patients were 37.5±12.4 years old (mean±S.D.)(M:F=5:8), and their sputum was culture positive even with adequate medication for prolonged periods (109.7±132.0 months), resistant to 2-8 drugs including isoniazid and rifampin. All patients had localized lesion(s) and most (92.3%) had cavities. At least 3 sensitive anti-TB medications were started before surgery in all patients according to the drug sensitivity test. The preoperative FE1 was 2.37±0.83 L. Lobectomy was performed in 11 patients and pleuropneumonectomy in two. Postoperative mortality did not occur, but pneumonia occurred as a complication in one (7.7%). After 41.5±58.9 days (range 1~150 days) follow up, negative conversion of sputum culture was achieved in all patients within 5 months. Only one patient (7.7%) recurred 32 months after lung resection. CONCLUSION: When medical treatment alone is not successful, surgical resection can be a good treatment option in patients with localized MDR PTB.

8.Percutaneous Pulmonary Valve Implantation.

Pulmonary regurgitation (PR) is a frequent sequelae after repair of tetralogy of Fallot, pulmonary atresia, truncus arteriosus, Rastelli and Ross operation. Due to patient growth and conduit degeneration, these conduits have to be changed frequently due to regurgitation or stenosis. However, morbidity is significant in these repeated operations. To prolong conduit longevity, bare-metal stenting in the right ventricular outflow tract (RVOT) obstruction has been performed. Stenting the RVOT can reduce the right ventricular pressure and symptomatic improvement, but it causes PR with detrimental effects on the right ventricle function and risks of arrhythmia. Percutaneous pulmonary valve implantation has been shown to be a safe and effective treatment for patients with pulmonary valve insufficiency, or stenotic RVOTs.

PURPOSE: This study compared the marginal bone loss around dental implant that were placed in the canine areas of the mandibles and finded the survival rate of implants, marginal bone loss around implants and prosthetic complications in 10 patients treated with overdentures retained with Locator attachments. MATERIALS AND METHODS: Ten patients who had received implant retained overdentures in the mandibules using two implants and Locator attachments at Daegu Catholic University Medical Center from 2004 to 2010 were included in this study. Evaluations of the survival rate of implants, marginal bone loss and prosthetic complications were performed. RESULTS: Implants placed in this study showed a 100% survival rate and the average annual bone loss was 1.03 mm +/- 0.20 mm in the first year. The patients have verbally indicated that they are comfortable and that their overdentures function well. But, implant retained overdentures had various prosthetic complications such as male change, relining, rebasing and denture fracture. CONCLUSION: Implant retained overdentures using two implant and Locator attachments in the fully edentulous mandibles is considered as a stable way for long terms because of minimal invasive operation, simple prosthetic process and easy repair.

Korean Journal of Urology 2005;46(7):695-699
PURPOSE: To investigate whether the preoperative prostatic biopsy values predict the tumor stage in radical retropubic prostatectomy (RRP) specimens. MATERIALS AND METHODS: We reviewed the prostatic needle biopsy findings in 69 patients, diagnosed with clinical organ confined prostate cancer, and who underwent a RRP between December 2003 and November 2004. The biopsy specimens were assessed for the number and maximal tumor length of positive cores and for the Gleason score. The preoperative serum prostate-specific antigen (PSA) level and prostate volume were measured using transrectal ultrasonography (TRUS). TRUS guided biopsies of 13.7 2.2 sites were performed. The preoperative values were compared with the pathological stage of the RRP specimens. RESULTS: Of the 69 patients, 53 (76.8%) had organ confined cancer and 16 (23.2%) had extraprostatic extension (pathologic T2 and T3 or greater, respectively), with mean ages of 65.6 and 65.1 years, respectively. The mean PSA levels were 8.0 and 13.0ng/ml and the prostate volumes were 38.3 and 33.8ml, respectively. The age, prostate volume, biopsy Gleason score and preoperative PSA level were not significant factors for predicting the pathological stage inform a multivariate analysis (p>0.05). The number (p=0.007) and maximal tumor length of positive cores (p=0.046) were significantly higher in those with an extraprostatic stage than in the organ confined cancer group. The optimal maximal tumor length and number of positive cores for the detection of extraprostatic cancer were 7.5mm and 6.5, respectively. CONCLUSIONS: The number and maximal tumor length of positive cores were strong predictors of the pathologic stage in the RRP specimens.
