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.

One case of congenital cutis aplasia is presented. The defect involved includes full-thickness skin defect of scalp and cranium. The patient was treated with debridement of dirty necrosed crust which covered exposed dura mater and with double opposing rotation flap including pericranium for bone regeneration. The donor site was covered with skin graft from right thigh. During operation, the superficial temporal artery was found to be short and weak. And after operation, the margin of flap were congested and finally necrotized. The necrotic wound was treated with conservative management. The vascular impairment is thought to be main course of congenital cutis aplasia. So we conclude that the treatment of choice is conservative management or careful flap surgery for coverage of defect area.

Albinism is a hereditary disease caused by the defect of tyrosinase that converts tyrosine to dihydroxyphenylalanine (DOPA). `Oculocutaneous albinism' is classified as hypopigmentation of skin, hair and eyes, but incidences of `ocular albinism' where hypopigmentation is limited to eyes are found rarely. Biochemically, albinism is caused by the tyrosinase activity. Typical findings in oculocutaneous albinism include not only ophthalmologic problems such as hypopigmentation of skin, foveal hypoplasia, photophobia and decreased visual acuity but also congenital nystagmus. We cannot determine distinctive characteristics of nystagmus of albinism because domestically, there are only a few reports that have been recorded correctly about nystagmus of albinism. Merely, we present our experience of two cases of albinism with congenital nystagmus because we think that these two cases, showing different types of nystagmus and electronystagmography, stand for the two representative types of nystagmus found in the literature up to date.

An association study with Korean alcoholic patients(n=50) and normal controls(n=53) was performed to find the relationship between catechol-O-methyltransferase(COMT) gene polymorphism and alcoholism using polymerase chain reaction-restriction fragment length polymorphism. When we compared the allele and genotype frequencies of Nla III COMT gene polymorphism in alcoholism and normal controls, there was no significant difference between two groups. Our results do not support an association between the Nla III polymorphism of COMT gene and alcoholism.

BACKGROUND AND OBJECTIVES:Traditionally, down beat nystagmus is regarded as a sign of central nervous system dysfunction. But, several years has passed since Herdman et al reported the down beat nystagmus developed during treatment maneuvers for posterior semicircular canal benign paroxysmal positional vertigo(BPPV). We undertook this study to evaluate the character and clinical analysis of the positional or positioning down beat nystagmus, to discuss the clinical significance of positional or positioning down beat nystagmus as a diagnostic criteria of superior semicircular canal BPPV, and to propose the new treatment method. MATERIALS AND METHOD:From November 1999 to March 2004, we sampled the 103 patients with positional or positioning down beat nystagmus. Of these patients, we selected 16 patients except for the patients with central nervous system dysfunction, nonspecific or artifact result, idiopathic origin. RESULTS:All of 16 patients had no sign and radiologic result of central nervous system disorder. 10 patients was reported or suspected the diagnosis of posterior semicircular canal BPPV. Fatigability was reported in 9 patients and reversibility was reported in 1 patient. Average latency was checked less than 2 seconds. CONCLUSION:Although the diagnostic criteria of superior semicircular canal BPPV that we reported was not controversial, we expect that this criteria is useful in diagnosis for patients with atypical positional or positioning down beat nystagmus. And the new treatment method that we reported will has the better results than previous method.

PURPOSE: A survey was performed to identify the level of mouthguard use, awareness, wearability issues and attitude toward mouthguard among elite Korean Taewondo athletes. MATERIALS AND METHODS: Survey questionnaires were given to 152 athletes participating in the Korea National Taekwondo team selection event for the 2010 Guangzhou Asian Games. Questionnaires consisted of three sections, mouthguard awareness, reasons for not wearing mouthguard and the last section to test the level of acceptance on current mouthguard and when the identified problems were resolved. For analyzing difference among response, chi2 test was used and significant level (alpha) was set up as 0.05. RESULTS: Responses in each of items showed significant difference (P<.001). Majority of response regarding each question: Majority of respondents believed that mouthguard were effective in preventing injuries (36.4%) but the result suggested that the provision of information on mouthguard to athletes was inadequate (44.0%) and the result showed that respondents were not greatly interested or concerned in relation to the mandatory mouthguard rule (31.6%). Although the responses on the level of comfort and wearability of mouthguard were negative (34.8%), athletes were positively willing to wear mouthguard if the problems rectified (51.2%). CONCLUSION: Considering the high level of willingness to wear mouthguard if the problems rectified, it is thought that together with efforts in providing more mouthguard information, the work of sports dentistry to research and improve mouthguard will be invaluable in promoting mouthguard to more athletes.

Dicamba is 3, 6-dichloro-2-methoxybenzoic acid and classified as a chemically related chlorophenoxy herbicide. This herbicide has been widely used for control of broad-leaved weeds. The poisoning is uncommon and of low toxicity, but massive self-ingestion may be fatal. We experienced a case of dicamba poisoning with rhabdomyolysis and acute renal failure in a 53-year-old male. This patient showed vomiting, confused mental status, and myotonia. Electrolyte abnormalities, rhabdomyolysis, and acute renal failure also developed together with fever, hepatotoxicity, pancreatic toxicity, hematologic abnormalities and cardiac ischemia. He was treated by 7 sessions of hemodialysis with supportive treatment and recovered.

Milk-Alkali syndrome can be caused by ingesting large amount of calcium and absorbable alkali. Coincident with promotion of calcium therapy for the treatment of osteoporosis in postmenopausal women and secondary hyperparathyroidism in patients with chronic renal failure, the Milk-Alkali syndrome is now a common cause of hypercalcemia. We experienced a case of a woman who had took calcium for hypoparathyroidism after thyroidectomy (and incidental parathyroidectomy) for thyroid papillary adenocarcinoma. Recently she ingested unusually large amount of calcium (10.8 g/day) for a week mistakenly. She presented voiding difficulty, anorexia and irritability with the triad of hypercalcemia, metabolic alkalosis and acute renal failure. All the metabolic abnormalities were normalized and renal function was improved with fluid and diuretic therapies.

BACKGROUND: Since the advent of AIDS, tuberculosis has become a major public health problem in the western society. Therefore, it is essential that pulmonary tuberculosis be rapidly diagnosed. Light microscopic detection of acid-fast organisms in sputum has traditionally been used for rapidly diagnosing tuberculosis. However positive smears are only observed in about one-half to three-quarters of cases. Studies using PCR for diagnosing pulmonary tuberculosis disclosed several shortcomings suggesting an inability to distinguish between active and treated or in active tuberculosis. In this study, the clinkcal significance of a PCR-bases rapid technique for detecting Mycobacterium tuberculosis DNA in peripheral blood investigated. MATERIALS AND METHODS: From July 1, 1998 through to August 30, 1999, 59 patients with presumed tuberculosis, who had no previous history of anti-tuberculosis medication use whithin one year prior to this study were recruite and followed up for more than 3 months. AFB stain and culture in the sputum and/or pleural fluids and biopsies when needed were performed. Blood samples from each of the 59 patients were obtained in order to identify Mycobacterium Tuberculosis DNA by a PCR test. RESULTS: 1) Forty five out of 59 patients had a final diagnosis of tugerculosis; Twenty eight were confirmed as having active pulmonary tuberculosis by culture or biopsy. Four were clinkcally diagnosed with pulmonary tuberculosis. The othe 13 patients were diagnosed as having tuberculous pleurisy (9) and extrapulmonary tuberculosis (4). 2) Fourteen patients showed a positive blood PCR test. The PCR assay correctly identified active tuberculosis in 13 out of 14 patients. The overall sensitivity and specificity of this blood PCR assay for diagnosing tuberculosis were 29% and 93%, respectively. The positive predictive value was 93%, the negative predictive value was 29% and diagnostic accuracy was 44%. 3) Six out of 14(43%) patients with blood PCR positive tuberculosis were immunologically compromised hosts. 4) A simple chest radiograph in blood PCR positive tuberculosis patients showed variable and inconsistent findings. CONCLUSION: A peripheral blood PCR assay for Mycobacterium tuberculosis is not recommended as screening method for diagnosing active tuberculosis. However, it was suggested that the blood PCR assay could contribute to an early diagnostic rate due to its high positive predictive value.
