Molecular epidemiology has been initiated for the confirmation of transmission link among tuberculosis patients. IS6110 restriction fragment length polymorphisms (RFLP) technique has been used as an excellent tool to discriminate Mycobacterium tuberculosis isolates, especially in tuberculosis (TB) outbreak in the population. IS6110 RFLP has the most discriminatory power for the M. tuberculosis isolates with high copy number of IS6110 like Korean isolates. Spoligotyping using spacers of direct repeat is useful to distinguish Beijing strains which are found widely in Eastern Asia, from non-Beijing strains. It is known that Beijing strains are more virulent, apt to be drug resistant than non-Beijing strains. Strain typing techniques of Mycobacterium tuberculosis has lead to the development of phylogenetic classification. Variable number tandem repeat (VNTR) of M. tuberculosis is another good target for strain typing. The technique using VNTR is rising as an alternative tool to overcome disadvantages of IS6110 RFLP which is time consuming in the sense that it takes longer time to process from the culture positive bacilli, and has the intrinsic difficulties in objectification of the results. The combination of many VNTR loci enhances discriminatory power to become equal to that of IS6110 RFLP. On the other hand, the optimal VNTR combination differs from one country to another due to different dominant clade. Large sequence polymorphisms (LSP) and single nucleotide polymorphisms (SNP) are important tools for the classification of the phylogeny of M. tuberculosis complex. Many previous reports indicate that the depending upon the type of strains, the ways of transmission of disease, the way to get infected with disease and the development of drug resistance conditions are variable. Therefore, the molecular epidemiology of M. tuberculosis has become more important for tuberculosis control in the world. It will be possible to set up tuberculosis-tailored policy after the characterization of M. tuberculosis by molecular epidemiologically.

There have been controversies on the rationale, surgicl indication, technique and results of meniscus repair.. Authors comparatively studied 100 cases of meniscus injury in 88 patients (arthroscopic total menisectomy: 16 cases, arthroscopic partial menisectomy: 68 cases, arthroscopic meniscus suturing: 16 cases) from February 1985 to March 1992. The results were as follows: 1. Male (61.4%) was much more affected than female. 2. The third decade group was most commonly affected and the most common causes was sports injury (43.2%) 3. The lateral meniscus was more injured (71%), than the medial (29%) 4. In arthroscopic finding, longitudinal tear (37%) was the most common. 5. According to the Tapper and Hoover's criteria, satisfactory result was 56.3% in arthroscopic meniscus repair group.

Leiomyoma is one of the rarest solid tumor of the ovary. Approximately 50 cases have been published to date. However, most reported leiomyoma of the ovaries were small and rarely induced serious symptoms. We report a case of ovarian leiomyoma in 57-year-old woman which has been experienced in our haspital with brief review of literature.

BACKGROUND: Almost all STD(sexually tranamitted diseases) have been increasing worldwide since the 1960s. In Korea, the occurrence of STD from recent trends of sexual openness and development in the pleasure-seeking industry is becoming a social issue. However, epidemiological studies and reports concerning the incidence of STD are lacking in Korea, especially in the sexually aetive young age group. OBJECTIVE: We evaluated the incidence of YTD and sexual behavior of recruits in a Korean arrny training center to contribute to the management of STD in Korea. METHODS: We studied 1304 recruits in a Korean army training center by questionnaire, physical examination and laboratory data. The subjects were divided into 3 groups: group 1(1072 persons), those who visited the hospital for evaluation of STD; group 2(641 persons), a control group for coitus rate; and group 3(1304 persons; group 1 plus 232 persons out of group 2), those who had coital experiences. RESULTS: 1. The incidence of STD in group 1 was 65.7%(704/1072) and that of the total number of recruits was 0.43%(704/164,134). 2. Among the 704 cases of STD, the most frequently observed STD was non-gonococcal urethritis, 292 cases(41.5%) and the second was gonorrhea, 236 cases(33.5%). The others were, 68 cases(9.7%) of pediculosis pubis, 41 cases(5.8%) of condyloma acuminatum, 29 cases(4.1%) of syphilis, 20 cases(2.8%) of combined STD, 14 cases(2%) of herpes progenitalis, 2 cases(0.28%) of molluscum cohtagiosum and 2 cases(0.28%) of chancroid. 3. The coitus rate in group 2 was 36.2%(232/641). 4. The incidence of previous STD in group 3 was 20.9%(273/1304). 5. The mn;t common form of STD which the patients experienced previously was urethritis(82.8%) and the others were pediculosis pubis(7.3%), syphilis(3.3%), condylcena acuminahun and herpes progenitalis. 6. The group with more sexual partners tended to have a lower educational level. 7. The experience rate of drug abuse was higher in the group with more sexual partners. 8. The experience rate of oral and anal sex was higher in the group with experiences of clrug abuse than in the ather one. CONCLUSION: In this study, urethritis was the most common form of STD(75% of all STD) and non-gonococcal urethritis showed a greater incidence than gonorrhea. The incidence of STD is thought to be closely related to the factors associated with social or behavioral science, such as the number of sexual partners, grade of education, drug abuse, experience of oral and anal sex. To accomplish more effective management of STD, therefore, the improvement of current social problems involving sexual openness, the pleasure-seeking industry and drug abuse should be achieved.

The authors accessed the effects of heart rate and age to echocardiographic right ventricular systolic time intervals in 27 cases with normal pulmonary artery pressure and correlation of pulmonary hemodynamic parameters with echocardiographic right ventricular systolic time intervals in 76 cases with congenital and acquired valvular heart diseases. The results were as follows; 1) As heart rate increased there was a diminution of the length of right ventricular ejection time(RVET)(r=0.642), but no significant changes in the length of right ventricular pre-ejection period(RVPEP) and the ratio of RVPEP/RVET were found. 2) As age increased there was an increase in the ratio of RVPEP/RVET(r=0.46), but no significant changes in the length of RVPEP and RVEF were found. 3) In patients with the RVPEP/RVET of 0.3 or more this ratio can predict that pulmonary artery systolic pressure is >30mmHg(sensitivity : 83%, specificity : 96%, accuracy 88%), pulmonary artery mean pressure >20mmHg(sensitivity : 87%, specificity : 96%, accuracy 90%), and pulmonary artery diastolic pressure >15mmHg(sensitivity : 86%, specificity : 90%, accuracy : 88%). 4) In patients with the RVPEP/RVET of 0.4 or more this ratio can predict that pulmonary artery systolic pressure is >50 mmHg(sensitivity : 75%, specificity : 98%, accuracy : 92%), pulmonary artery mean pressure >40mmhg(sensitivity : 93%, specificity : 96%, accuracy : 96%), pulmonary artery diastolic pressure >25mmHg(sensitivity : 75%, specificity : 98%, accuracy : 92%), pulmonary vascular resistance >6 units(sensitivity : 70%, specificity : 96%, accuracy : 89%), and Rp/Rs >0.25(sensitivity : 86%, specificity : 95%, accuracy : 93%). In conclusion, pulmonary hypertension, increased pulmonary vascular resistance and pulmonary arteriolar obstructive disease can be predicted by echocardiographic measurement of RVPEP/RVET.

It is thought to be reliable roentgenologic sign of pulmonary plethora that the diameter of anterior segmental artery(d-ASA) is larger than that of anterior segmental bronchus(d-ASB). To evaluate the reliability of this sign, we compared d-ASA with d-ASB on chest rentgenograms of 100 normal adults. Of the total 105 cases. d-ASA was larger than d-ASB in 40 cases (38.1%), smaller than d-ASB in 34 cases(32.4%) and equal to (d-ASA and) d-ASB in 31 cases(29.5%). The ratio(ABR) and difference between d-ASA and d-ASB ranged from 0.70 to 1.58(mean, 1.05±0.30) and from -1.85mm to +2.45mm(mean of absolute value, 0.75mm±0.57). These results showed that the relationships between d-ASA and d-ASB were variable. Conclusively, d-ASA may be larger than d-ASB in even normal adults and mild degree of pulmonary plethora cannot exectly evaluated with this findings only.
