BACKGROUND: According to the 1992 version of ACLS guideline, adenosine is recommended as the first line drug far the treatment of paroxysmal supraventricular tachycardia(PSYT). But adenosine is not used frequently in our country, despite currency proven effect and safety. Therefore we tried to compare the efficacy and safety of adenosine with verapamil for the treatment far PSVT. MATERIALS AND METHODS: We prospectively reviewed charles of PSVT patients admitted to YongDong Severance Hospital from Jan. 1995 to Dec. 1996. These patients were randomly divided into two groups. The flat group was given 6mg of adenosine initially, and another 12mg was given within 5 minutes if fast dose failed. The other group was given 5mg of verapamil initially, and if failed, 10mg was given within 10 minutes. The results were analyzed by Chi-square test and student-t method. RESULTS: In converting PSVT to normal rhythm, adenosine and verapamil showed similar results and there was no difference between the two Groups in frequency of side elects, but serious arrhythmia such as ventricular fibrillation and ventricular tachycardia was not seen in the adenosine group. CONCLUSION: Adenosine not only showed comparable effect and safety, but also had shorter action time than verapamil. Therefore we recommand adenosine, as a safe and effective fort line drug for PSVT.

This paper shows anthropometric differences among four regions of urban community using Korean anthropometric data surveyed in 1992. The anthropometric data include 84 measurements of Korean aged 12~50. The principal component analysis reduce 84 measures to five components. The discriminant analysis using these components is performed to observe the anthropometric differences among four regions : Seoul and Kyungki, Kangwon and Chungbuk, Chungnam and Ch lla, Kyungsang. The results on age groups (12~14, 15~17, 18~24, 25~50 ages) and city size (big city, medium city, small city) can be summarized as follows ; 1) In male aged 12~14 and 15~17, there are significant differences of anthropometry among four regions in all city size. But in another age groups (18~24 and 25~50 ages), these are not significant differences of anthropometry among four regions except medium city. 2) In female, there are significant differences of anthropometry in all city sloe in aged 18~24 and 25~50 and in medium city in aged 15~17. however, there are not significant differences in aged 12~14 and 15-17.

Erdheim Chester disease (ECD) is very rare non-Langerhans cell histiocytosis (LCH) which occurs in the skeletal system and multiple organs. As it is progressive, sometimes it causes fatal results. However, it is often misdiagnosed as LCH or multiple bone metastasis and, thus, is very difficult to diagnose. In Korea, only 10 cases were first reported in 1999. In particular, there have been a few orthopedic approaches or reports in English-speaking literatures, and no report has been issued in Korea. The authors performed bone biopsy in patients with knee and lower extremity pain who were referred for the integrated treatment. We attempts to report this diagnosis experience with literature review.

PURPOSE:Varying clinical phenotypes are associated with the chromosome 22q11.2 microdeletion syndrome. The endocrine manifestation are latent or overt hypoparathyroidism, thyroid dysfunction and short stature. This study was undertaken to investigate frequencies of endocrine abnormalities and short stature in patients with the chromosome 22q11.2 microdeletion syndrome. METHODS:Forty three unrelated patients were diagnosed having chromosome 22q11.2 microdeletion syndrome. Chromosomal microdeletion was confirmed by fluorescent in situ hybridation (FISH) with DNA probe (22q11.2 LSI TUPLE1 from Vysis). Serum total calcium and intact parathyroid hormone (PTH) were measured in all patients. Thyroid function tests including free thyroxine(T4), thyroid stimulating hormone (TSH) and thyroid autoantibodies were performed in all patients. Insulin-like growth factor-1 (IGF-1) was measured in 10 patients. Height, weight and body mass index were compared with chronological age in all patients. RESULTS:Seven patients (16%) had an overt hypoparathyroidism, presenting with hypocalcemic tetany. Thirteen patients (31%) showing hypocalcemia with normal PTH were regarded as having latent hypoparathyroidism since their PTH secretion response was blunted. Out of 2 patients with thyroid diseases, one patient had Graves disease and the other had Hashimoto thyroiditis. Five patients (12%) were below the 3rd percentile in height at evaluation. The BMI was below the 5th percentile in 23% of patients. CONCLUSION: Twenty patients (47%) presented with overt and latent hypoparathyroidism. Interestingly, autoimmune thyroid diseases such as Graves disease and Hashimoto thyroiditis were associated in patients with chromosome 22q11.2 microdeletion, indicating predisposition to autoimmune disorders. Therefore, a careful endocrine and growth evaluation is needed in these patients.
