This study was designed to validate the usefulness of the near point of convergence(NPC)test in determination of dominant & non-domnant eyes in intermittent exotropia patients. We performed NPC test in 36 intermittent exotrpic patients, and then, determined the non-dominant eye which deviated outward beyond the NPC. The dominant eyes determined by the NPC were compared to those that were determined by amblyopia, sensory fusion and photophobia. Best corrected visual acuity was used to divide patients into two groups : 26 patients without amblyopia, and 10 with amblyopia. Among the amblyopia group, if the eyes with better visual acuity were taken as dominant eyes, then eight(80%)cases were identical with the NPC test and two(20%)cases were different. Ten patients had sensory anomaly, and among then, nine(90%)cases were identical with the NPC test and one(10%)case was different. Twenty six(64%)patients had photophobia in one eye and all(100%)cases were identical with the NPC test. In intermittent exotropia, determination of dominant eye by the NPC test showed high coincidence with other tests. Therefore, we suggest that the NPC test is an easy and accurate method in determining either the dominant or non-dominant eye for surgery.

Between sept. 1982 and June 1985, the authors have performed arthroscopic debridement on 32 knees of 30 patients with primary osteoarthritis of the knee. Operative procedures including lavage, partial meniscectomy, excision of shelf, partial or total synovectomy of the anterior compartment, debridement of the articular cartilage, removal of loose bodies and multiple drilling of the articular cartilage were variously combined case by case. The follow-up period was between 18 and 52 months, with on average of 30.6 months. Clinical results were evaluated with the modified method of Sprague, III and were classified “Excellent”. “Good”, “Fair” and “Poor”. The data were analyzed by Fishers exact test to clarify the relationship between clinical results and various preoperative factors. The results were as follows: l. Of the total 32 knees, results were “excellent” in 17(53.1%), “good” in 9(28.1%), “fair” in 3 (9.4%) and “poor” in 3(9.4%) knees respectively. Satisfactory results, including “excellent” and good, were achieved in more than 3/4 cases(81.2%) . 2. Of the 3 “poor” cases, 2 cases seemed to be affected by major depression and the other one case had no specific cause to be considered. 3. The unsatisfactory cases, including “fair” and “poor” cases, commonly had degenerative changes of patellofemoral joint arthroscopically although the correlation between it and the results were not significantly proved statistically(P>0.05). 4. The correlation between amount of effusion, degree of degeneration of articular cartilage and amount of fibrinoid debris were not significantly proved statistically(P>0.05). 5. The correlation between clinical results and amout of effusion. degreq or site of degeneration of articular cartilage, degree of flexion contracture, meniscal tear, synovectomy, debridement of articular cartilage and number of operative procedures could not be significanly proved statistically. In conclusion, arthroscopic treatment of the primary osteoarthritis of the knee shows relatively satisfactory results in most cases with fewcomplications and a short rehabilitation period, and the procedure could be recommended as a process inbetween conservative treatment and definitive treatment such as total knee replacement. But any specific relationship between clinical results and various preoperative factors could not be proved statistically. The clinical results seemed to be attected by individual unknown factors and further precise analysis and long term follow-up will be necessary to clarify them.

BACKGROUND: HBsAg carriers are 6-12% of population in Korea. The patients knowledge on hepatitis B and regular follow-up tests are important, because HBsAg carriers have infectivity and the disease may progress without symptoms. We surveyed their knowledge on the hepatitis B and the frequency of follow-up blood test and sonogram. METHODS: From March 1993 through September 1994, 630 patients who were diagnosed as HBsAg positive and Anti-HBs negative in a health promotion center of college hospital were surveyed by mailing questionnaire. The questionnaire included the result of HBV viral marker test, transmission routes, complications, and prevention methods of Hepatitis B, frequency of follow-up test, and doctors recommendation. RESULTS: Of the 490 questionnaires excluded the 140 questionaires returned due to wrong address, 100 were answered, making the reply rate 20.4%. As for the result of HBV marker test, 64% answered their HBV marker as HBsAg positve, 10% answered HBsAg negative, and 26% answered I dont know. 65% answered that they are HBV carrier. As for the mode of transmission, 59% answered that HBV is transmitted by blood, 57% from carrier mother at birth, 29 % by sexual intercourse. 76% of responders know that vaccination is needed for preventing vertical transmission. When making score on their knowledge, significant differences were showed according to education, income and doctors recommendation about regular follow-up test. The number of persons who took regular blood test every 6 to 12 months were 56(56%), and the number of persons who took regular abdominal ultrasonogram were 39(39%). The number of patients who were recommended regular follow-up by doctor was 76%. In this group, 51 persons(67.0%) took regular blood test and 35 persons(35%) took regular sonogram so this frequency is significantly higher than the other group(each 20.8%, 16.7%). CONCLUSIONS: The knowledge on hepatitis B in HBsAg positive patients is relatively low and the frequency of regular follow-up test is significantly higher in the group who took doctors recommendation. So it is very important that HBsAg carriers must be educated about the infectivity, preventive methods, and regular follow-up for early detection of complication like hepatocellular cancer.

Ovarian cysts in the newborn are uncormnon. Fetal ovarian cysts are being diagnosed with inaeasing fiequency with development of obstetrical sonography. Most of these cysts are found within the first few months of life and have no clinical significance. But, a large ovarian cyst would be founded antenatally with sonography. A large ovarian cyst can cause life-theatening complications during parturition and in the neonatal period. We have experienced a case of fetal ovarian cyst in a 32-year-old primiparous woman with antenatal sonography and report our experience with a brief review of literatures.

BACKGROUND: The Amplified Mycobacterium tuberculosis Direct Test (AMTDT) has been developed for the direct detection of M. tuberculosis complex in respiratory specimens. Traditional methods for diagnosis of extrapulmonary tuberculosis such as the acid-fast bacilli (AFB) stain have their well-known limitations. We investigated the usefulness of the AMTDT for a wide range of non-respiratory specimens to establish early diagnosis of extrapulmonary tuberculosis. METHODS: 346 specimens (219 urine, 117 pleural fluid, 6 ascitic fluid, 2 lymph node, 1 gastric aspirate, and 1 pus specimens) from 340 patients referred from November 1997 to September 1998 were tested by the AMTDT. The AMTDT results were evaluated by comparing with clinical diagnosis and smear results. RESULTS: The overall sensitivity, specificity, and positive and negative predictive values of the AMTDT were 82.9%, 93.8%, 64.2%, and 97.6%, respectively. There were no difference in sensitivity and specificity between pleural fluid and urine specimens. In 31 specimens from tuberculosis patients concurrently tested with AMTDT and stain, 15 were only AMTDT positive and 4 were only stain positive. Among the results considered to be false positive, 47.2% of cases were shown as being less than 150,000 relative light units (RLU). In 30 specimens from tuberculosis patients during or after treatment, all six of the patients with reactivation or aggravation were AMTDT positive, and one case was considered to be false positive. CONCLUSIONS: Our study demonstrates the efficacy of the AMTDT in diagnosing extrapulmonary tuberculosis. Prudent interpretation of the AMTDT's results is recommended in case of that being less than 150,000 RLU.

To date, the unilateral single vaginal ectopic ureter has been regarded as the rarest form of ureteral ectopia because 80 per cent of all ectopic ureters are associated with a duplicated system and most of the ectopic ureters occur in male patients. This malformation may take the form of but is not limited to any ombination of abnormal development of the mesonephric and paramesonephric ducts. We report a case of unilateral single vaginal ectopic ureter with ipsilateral hypoplastic kidney in a 9 year-old female patient who has been suffered from diaper dermatitis due to persistent urinary incontinence since birth.
