PURPOSE: Supraventricular tachycardia(SVT) is the most frequent symptomatic arrhythmia in children. We performed this study to disover the SVT mechanisms, age at SVT onset, symptoms and ECG findings of SVT and effect of adenosine on SVT. METHODS: We studied 57 patients(male : 30, female : 27, age : 1 day-15.8 years) who had been admitted or transferred due to SVT from January, 1997 to March, 2001. Retrospectively we reviewed their medical records, ECG and electrophysiologic study findings. RESULTS: Of the total 57 patients, the mechanisms of SVT(including atrial flutter) were atrioventricular reentrant tachycardia(AVRT) in 36(63%) patients, atrioventricular node reentrant tachycardia(AVNRT) in 9(16%) patients, ectopic atrial tachycardia(EAT) in 6(11%) patients, multifocal atrial tachycardia(MAT) in 3(5%) patients and atrial flutter(AF) in 3(5%) patients. Of the 12 primary atrial tachycardias(including EAT, MAT and AF), 11 tachycardias began before 1 year of age. The SVT occured before 1 year of age in 21(37%) patients, at 1 to 5 years of age in 7(12 %) patients, at 5 to 10 years of age in 19(33%) patients and after 10 years of age in 10(18%) patients. In symptomatic SVT, the frequent symptoms were palpitation, chest discomfort and chest pain, gastrointestinal symptoms including nausea and abdominal pain, dizziness and dyspnea in decreasing frequency. P wave was discernible in 31(86%) of the 36 AVRT patients and 5(56%) of the 9 AVNRT patients. Adenosine was effective in 19(91%) of 21 AVRT or AVNRT patients. No significant side effect resulted from was occured by rapid bolus intravenous injection of adenosine. CONCLUSION: AVRT was most frequent in pediatric SVT patients. SVT frequently occured before 1 year of age and at 5 to 10 years of age. Primary atrial tachycardia mainly occured before 1 year of age.

In order to provide some basic data for the control of air water pollution in Korea, the suthors have estimated the amount of air and water pollutant emitted from industries which are employed over 20 employes. This study have done from July 1, 1972 to the end March 1973. The results are as follows: 1. Total number of establishments tith over 20 employees is 5,197 in Korea and the largest gorup establishments was the manufacturing of texttiles with 1,363 establishments(26.2%). 2. By order of number of employees it was observed that there 2,800 industries with 20-59(53.9%) employees, 1,101 with 50-99(21.2%), 571 with 100-199(11.0%), 501 with 200-499(9.6%) and 225with over 500(4.3%) respectively. 3. By order of regional distribution, it was observed that there were 2,257 industries in Seoul (43.3%) and 736 industries in Pusan(14.2%). 4. Industrial coal consumption was 596,154 M/T in 1972, but it'11 be 315,000 M/T in 1980, Fuel consumption was 4,972,000 K1 in 1972, and estimated volume will be 19,3700,000 K1 in 1980. 5. Ttotal amounts of air polutants emitted from industris by fuel combustion were sulfur oxides 79,459 tons, carbon monoxide 33,908 tons, particulate 31,304 tons and hydrocarbon 30,280 tons in 1972 but in 1990 there will be sulfur oxides 1,010,474 tons, nitrogen oxides 204,575 tons, carbon monoxide 68,014 tons, particulate 64,820 tons and hydrocarbon 67,622 tons, respectively. 6. Annual emitted air pollutants through the working processes were sulfur oxides 91,250 tons and nitrogen oxides 32,485 tons in 1972, but sulfur oxieds 118,625 tons and nitrogen oxides 42,555 tons will be present in 1980, respectively. 7. Annual emitted air pollutants by national unit area amounted to 0.77 tons/km2/year in 1965 and 14.7 ton/km2/year in 1980. 8. Total industrial wastes from all industries in Korea were estimated at 810,360 tons/day in 1972; manufacturing of chemicals and plastic products showed the highest amount of wastes at 470,000 tons/day. 9. The amounts of water pollutants due to industrial wastes were the .B.O.D., 471.5 tons/day,suspended solid 331.5 tons/day, CN, 2.3 tons/day, and Cr. 3. 4 tons/day in 1972, but it might be evident of a B.O.D of 3.388 tons/day, suspended solid 2,544 tons/day, CN 20.1 tons/day, and 26.5 tons/day in 1990. 10. Total population equivalent of B.O.D. was 943,000 in 1972, and the estimated value in 1990 will be6, 780, 000.

Lichen sclerosus et atrophicus (LSA) is an uncommon condition of the skin with small white macular or atrophic plaques which predominantly affects the genital regions of middle aged and elderly women. We present an atypical case of LSA on a 58 year old woman. The patient had a brownish-black colored patch of 2.5 * 7.0 cm in size on the right clavicular area of one year's duration. The histopatholgy of the lesion disclosed classical findings of LSA. A marked incontinence of pigment is noted in the upper dermis which accounts for the clinical picture of the lesion. She was treated with topical hydrocortisone cream resulting in a marked diminution of pigmentation.

PURPOSE: Today, many patients with voiding dysfunction select suprapubic cystostomy (SPC) instead of clean intermittent catheterization (CIC) for practical reasons. There is thus a need to reconsider SPC as a management for voiding dysfunction. We designed SPC with timed drainage (TSPCD) and evaluated its effectiveness compared with continuous drainage with a urine bag (CSPCD). MATERIALS AND METHODS: Between January 2006 and January 2010, a total of 82 patients underwent SPC. Patients undergoing SPC were randomly assigned to CSPCD or TSPCD. Patient characteristics, complications, and the results of urine cultures were compared between the two groups through retrospective chart reviews. Also, preferences for CSPCD and TSPCD in another 15 patients who had experienced both CSPCD and TSPCD were investigated. RESULTS: The CSPCD and TSPCD groups comprised 46 and 36 patients, respectively. In a comparison of complications between the two groups, the incidence of acute symptomatic cystitis was significantly lower in the TSPCD group than in the CSPCD group (43% vs. 20%, p=0.032). The incidence of symptomatic urinary tract infection (UTI) was lower in the TSPCD group. Positive urine culture rates were 89.7% and 72.4% in groups 1 and 2, respectively. There was a significant difference between the two groups (p=0.004). In another 15 patients who experienced both CSPCD and TSPCD, 14 patients (93%) stated a preference for TSPCD after converting from CSPCD to TSPCD, and one patient (7%) returned to CSPCD only at night. CONCLUSIONS: In this study, TSPCD had the advantages of less morbidity as UTI and being more preferable by patients with relatively good daily activity compared with CSPCD. TSPCD is an alternative to CSPCD for the treatment of voiding dysfunction.
