Atrial fibrillation(AF) diagnosed by fibrillatory waves of atrial activity and an irregular ventricular response on ECG is a common arrhythmia associated with increased cardiovascular morbidity and mor- tality. The incidence of AF increases markedly with advancing age and the presence of congestive heart failure. Most patients with AF can be attributed to organic heart disease such as rheumatic, atherosclerotic and hypertensive heart disease. But there is an increasing awareness of so-called lone AF which has no underlying cardiac or metabolic abnormality. We report a case of paroxysmal AF developed just before the induction of anesthesia in a 73-year-old patient who had no history of cardiovascular disease.

Juvenile spring eruption(JSE) of the ears is an unusual type of photodermatosis, which develops on the light exposed areas of the ears of boys and young male adults in the early spring months. JSE has received little attention in the literature, and to our knowledge no cases have been reported in Korea until now. Herein we report a case of JSE occurring in a 17-year-old man who has suffered from a recurrent pruritic erythematous papulovesicular eruption of both helix, followed by crusting and healing without scarring within one to two months early each spring for six years.

Trichloroethylene (TCE) is currently used as a degreasing agent in the jewelry manufacturing industry. The characteristic sign arising after the exposure of TCE are hepatitis and contact dermatitis. The incidence of toxicity is relatively rare, therefore, the mechanism of occurrence is considered as hypersensitivity. A previously healthy 21-year-old male began to work at jewelry industry. The solvent used in that place was TCE. Over the next month, he experienced symptoms of weakness, fever, dry skin, red rash and bumps, peeling face, and jaundice. At that time, he had marked liver enzyme elevation with evidence of cholestasis. After two weeks of avoidance of TCE exposure, his liver enzymes showed a marked reduction in ALT from a peak of 1132 to 131 IU/L. The total bilirubin reduced from 9.3 to 4.6 mg/dL. Tests for hepatitis A, B, and C, CMV, HIV were all negative. The patch test showed primary irritant reaction to TCE and its metabolite, trichloroethanol. This is the second report of TCE induced hepatotoxicity in Korea. We consider this case as a TCE induced hepatotoxicity due to possibly hypersensitivity mechanism.

OBJECTIVE: Arrhythmogenic right ventricular cardiomyopathy(ARVC) is a progressive cardiac muscle disease characterized as progressive fibrofatty replacement of the right ventricle, severe ventricular arrhythmia, and sudden death. However, there is no report of ARVC as a cause of sudden death in Korea. METHODS and RESULTS: Postmortem studies were done to 115 cases of sudden unexplained death at department of legal medicine, school of medicine, Kyungpook national university in year 1999. We identified 7 cases(6%) of typical ARVC with no other identifiable cause of sudden death. The subjects included 5 males and 2 females, ranging in age from 19 to 41 years (mean 29.7 years). All were found dead at bed (5 cases) or workshop (2 cases). Five cases were fibrofatty types and two cases were fatty types. Right ventricular aneurysm, inflammatory infiltrates and left ventricular involvement were found in 4, 2 and 1 cases, repectively. Two cases had family history of sudden death before age 40. No one was suspected of having cardiovascular disease or ARVC before death. CONCLUSION: These findings indicate that ARVC in Taegu-Kyungpook area may be more frequent than previously thought. ARVC may be a major cause of sudden unexplained death.

OBJECTIVES: This study was conducted to determine the reference interval of serum thyroid hormones (TSH, FT(3), FT(4)) in healthy Korean adults. METHODS: Health examination data from 1,591 healthy Korean adults who visited an university hospital were analyzed. Patients with specific health conditions capable of altering laboratory results were excluded from the study. Serum thyroid hormones were measured using IMMULITE 2000 (DPC, USA, 2002). Subjects were 18-65 years old; 911 were male, and 690 were female. RESULTS: The arithmetic means of TSH, FT(3), and FT(4) values for male subjects were 1.28+/-1.84 micronIU/ml, 3.23+/-0.57 pg/ml, and 1.42+/-0.22 ng/dl, respectively. In female subjects, the arithmetic means of TSH, FT3, and FT4 values were 1.49+/-2.08 micronIU/ml, 3.08+/-0.54 pg/ml, and 1.29 +/-0.24 ng/dl, respectively. The arithmetic mean FT(4) value for males decreased with age (p<0.01). The arithmetic mean FT(3) value for females increased with age (p<0.01). The arithmetic mean thyroid hormone values of all study subjects differed significantly based on season. The arithmetic mean of male FT(4) decreased with increasing BMI (p<0.01). The arithmetic mean of female FT(3) increased with increasing BMI (p<0.01). The reference intervals recommended by the IMMULITE 2000 manufacturer are 0.40-4.00 micronIU/ml for TSH, 1.80-4.20 pg/ml for FT(3), and 0.80-1.90 ng/dl for FT(4) (same values for both genders). CONCLUSIONS: There was a significant difference in the interval of thyroid hormones between males and females, but the reference interval of IMMULITE 2000 was not established by gender. There is a need to reestablish the reference interval for thyroid hormones in Korean healthy adults.
