BACKGROUND: Although the culture of urethral discharge using a cutton swab is regarded as one of the most sensitive and reliable diagnostic methods of gonorrhea, it may give pain or diagnostic methods of gonorrhea, it may give pain or discomfort to patients, and its detection rate may be influenced by the examiner's technical ability. OBJECTIVE: The purpose of this study was to compare the positive culture rates between ure4thral discharge and urinary sediment for the diagnosing of Neisseria gonorrheae. METHODS: We compared this technique with the culture of urethral discharge using the specimens from 357 male patients with gonococcal infection at VD clinic of Jungku Pvblic Health center in Seoul from Jan 1991 to Jun 1993. RESULTS: The culture of urinary sediment was positive in 339 of 357(94.95), whereas the culture of urethral discharge was positive in 346 of 357(96.95). However, these data have no statistical significance(P<0.05). The obe observed sensitivity and specificity of culture of urinary sediment comjpared to culture of urethral discharge were 97.75 and 90.9%, respectively. The predictive value of positive and negative test compared to the culture of urethral discharge were 99.7% and 55.65, respectively. As our data showed low negative predictive value, a negative culture result of urinary sediment does not always imply a negative culture result of urethral discharge. CONCLUSION: Therefore, at present, the previous method of the culture of urethral discharge is more highly recommended and further studies for this diagnostic and/or new method of gonorrhea based on larger group of patients is encouraged.

Chronic complication of diving and working in compressed air is dysbaric osteonecrosis. Dysbaric osteonecrosis could be diagnosed by simple bone x-ray, in the case of exposure history to dysbaric atmosphere. The case is 44 years old man who worked as a shell fish diver for 20 years. He was exposed dysbaric atmosphere during diving. He had bone necrosis in both femur head, both distal femur and proximal tibia. He had multiple attacks of decompression sickness. Other causes of bone necrosis are ruled out. We conclude that diver's bone necrosis is dysbaric osteonecrosis.

This study was designed to investigate dental arch shapes buccally and lingually at Bracket Level of Koreans. This involved studying 63 inviduals (37 males, 26 females) with normal occlusion ranging in age from 17 to 24 years old. The landmarks were digitized and measurements and statistical analysis were performed by NEC 9801 V-M computer. The Results were as Follows: Bicanine width, Bipremolar width and Bimolar width were larger in males than in females. Buccal and lingual arch form and coordination form were obtained by NEC 9801 V-M computer. The parabolic equations which represents buccal and lingual arch form were obtained.

BACKGROUND AND OBJECTIVES: Mast cells are localized in the middle ear and Eustachian tube. They play a prominent role in the inflammatory and allergic conditions. The purpose of this study is to investigate if different inflammatory reactions depend on whether patients are allergic or not by measuring concentration of the mast cell tryptase that reflects the mast cell activity. MATERIALS AND METHOD: Twenty-five patients with chronic otitis media with effusion (COME) were studied. Thirteen patients were confirmed allergy positive by multiallergosorbent test. Mast cell tryptase in the middle ear effusions was measured using western blotting. RESULTS: Mast cell tryptase was more strongly expressed in the effusions with allergy positive than in the allergy negative (p<0.01). CONCLUSION: There was a correlation between mast cell tryptase from MEE and allergy, so we conclude that allergy plays a role in the pathogenesis of COME.

OBJECTIVE: To investigate the frequency, nature and risk factors of musculoskeletal problems in pregnancy. METHOD: We obtained the information through a questionnaire and physical examination of full-term (gestational age over 38 weeks) pregnant women. Prevalence, onset time, severity and risk factors of musculoskeletal problems were analyzed. RESULTS: Among the 70 pregnant women, 37 women (53%) complained of low back pain which was the most common musculoskeletal problem in pregnancy. Other problems were hand symptoms (31%), lower extremity joint pain (31%), leg cramp (29%), chest pain, shoulder pain and neck pain. Previous history of low back pain was significantly correlated with the occurrence of low back pain in pregnancy. Weight gain during pregnancy and amount of time of housework during pregnancy were significantly correlated with carpal tunnel syndrome. Pregnant women suffering from leg cramp were significantly old in age. CONCLUSION: Prevalence of musculoskeletal problems during pregnancy was relatively high and several risk factors were related with occurrence of those problems. So, prophylactic risk factor control would be necessary to reduce musculoskeletal problems during pregnancy.

With the goal of providing optimal care to patients, student-centered active learning and the development of clinical competency have become vital components of the education of future physicians capable of sustainably coping with future challenges. However, the shape of future medicine is dramatically changing based on advances in information and communication technology, and the current classroom model seems to have difficulties in fully preparing students for the future of medicine. New trends in teaching and assessment methods include computer-aided instruction, virtual patients, augmented reality, human patient simulations, and virtual reality for the assessment of students’ competency. The digital technologies introduced in medical and dental education include Google Forms to collect students’ answers, YouTube livestreaming, Google Art & Culture (an online art museum), and choose-your-own-adventure as a story-telling technique. Innovations in digital technology will lead the way toward a revolution in medical and dental education, allowing learning to be individualized, interactive, and efficient.

The complications of peripheral or posterioruveitis, such as vitreous opacity, epiretinal membrance, and tractional retinal detachment may need vitreous surgery. This study was undertaken to evaluate the efficacy of transpars plana vitrectomy in the case of epiretinal membrance or tractional retinal detachment secondary to chronic uveitis.We included 23 eyes of 21 patients, and among them there was 16 eyes of epiretinal membrance and 7 eyes of tractional retinal detachment respectively. Improvement of vision, 2 lines or more in Anellen Chart, was noted in 10 eyes(63%) for epiretinal membrance and 2 eyes(29%) for tractional retinal detachment within post-operative 1 month. Final visual acuity decrease, compared with preoperative vision, was noted in 4 eyes(25%) for epiretinal membrance and 6 eyes(86%) for tractional retinal detachment with a mean follow-up of 34 months. The most common cause of visual acuity decrease was recurrent or persistent inflammation and resultant fibrous tissue proliferation, which became obvious within post-operative 3 months.Therefore, we`re able to conclude that the main cause of postoperative visual acuity decrease is persistent intraocular inflammation and fibrous change. So it is necessary to remove posterior hyaloid membrance actively and combine with medical treatment like corticosteroid therapy in order to control the inflammation even after vitreous surgery.

Scrotal leiomyosarcoma arising from dartos layer not involving the testis, epididymis or spermatic cord is very rare tumor. We report a case of scrotal leiomyosarcoma in 29 year old man who present with right scrotal painless growing mass. The lesion had been for 3 months but there was no related symptom such as pain or tenderness. The excised lesion was 3 x 3cm sized ovoid mass with smooth surface and it had no relationship with the testis, epididymis and spermatic cord. Its pathologic finding was compatible with leiomyosarcoma. So additional radical orchiectomy was done.
