Heat disorders are not uncommon in the military society due to supposedly hard training to overcome the environmental conditions. Twenty-two soldiers with heat disorders were admitted to Chin Hae Naval Hospital June 1969 through July 1970. Hoping that our clinical studies on them contribute to a renewed understanding, the results are reported in summary as follows: 1) Heat disorders occurred with an overall incidence of 3.1 per cent during running in early summer. 2) Of the twenty-two patients, eight (37 per cent) had heat cramps, six (27 per cent) heat exhaustion, five(23 per cent) heat stroke, and three(13 per cent) had undetermined disorder. 3) Ten patients(45 per cent) were comatous, and this occurred most frequently(80 per cent) among those with heat stroke. 4) All patients were grouped into four according to their physical status on admission. Those with heat exhaustion mostly belonged to group I (good) or group II (fair). Those with heat stroke and heat cramps eomprised most of group III (poor) and group IV (grave). 5) Group I and II patients recovered within 12 hours; group III, within 12~24 hours; and group IV, required more than 24 hours of care. 6) One patient with heat stroke, graded V, expired with sudden hypothermia 15 hours following admission. Overall mortality of heat disorders was 4.5 per cent, and that of heat stroke 20 per cent. 7) The rest recovered uneventfully within 19 hours of average.

Minicore myopathy, an uncommon condition, is one of congenital myopathies. It is characterized by multifocal areas of degeneration in muscle fibers. The minicores consist of numerous small areas of decreased oxidative enzyme activity. The axis of the lesion is perpendicular or parallel to the long axis of the muscle fiber. The phenotype has been described as predominantly proximal, static or only slowly progressive muscle weakness. We report a 4 year-old-girl with respiratory failure, thoracic scoliosis, hypotonia and facial weakness, who was diagnosed as minicore myopathy by muscle biopsy. The laboratory investigations, such as creatine phosphokinase and lactic dehydrogenase levels, and the nerve conduction velocity were normal. The muscle biopsy showed marked size variations of myofibers, marked endomyseal and perimyseal fibrosis, and moderate fatty changes in myofibers. The histochemical studies showed multiple focal losses of mitochondria. These findings are consistent with minicore type congenital myopathy.

PURPOSE: Atopic dermatitis may impair quality of life and lead to attention deficit-hyperactivity disorder (ADHD). Thymus and activation-regulated chemokine (TARC)/CCL17 may serve as a new biomarker for atopic dermatitis. We investigated the relationship between TARC and the severity of atopic dermatitis, quality of life, and ADHD. METHODS: A total of 249 preschool children who had atopic dermatitis were enrolled. Parents of the patients filled out a questionnaire on the past history of allergic diseases, quality of life, and ADHD. In each patient, total immunoglobulin (Ig) E and specific IgE to nine foods and inhalant allergens, total eosinophil counts, and TARC levels were measured. We evaluated the severity of atopic dermatitis by using the scoring atopic dermatitis (SCORAD) score and divided the patients into three groups; mild (<15), moderate (15 to 40), and severe (>40). RESULTS: In a total of 249 children, 222 children (89.2%) had a history of atopic dermatitis. Children with allergic sensitization had a higher SCORAD score, total IgE levels, and total eosinophil counts, but not TARC levels. Three groups by the SCORAD score showed significant differences in quality of life index and TARC levels but not in ADHD index. TARC level was correlated with the SCORAD score, but not with the quality of life index and ADHD index. The SCORAD score was correlated with the quality of life index but not with the ADHD index. CONCLUSION: Serum TARC levels may be associated with the severity of atopic dermatitis but not with the degree of quality of life and ADHD. Disease severity of atopic dermatitis in preschool children may be associated with the degree of quality of life but not with the level of ADHD.

PURPOSE: Environmental factors may increase risk for childhood asthma. The objective of this study was to investigate the association of environmental tobacco smoke (ETS) exposure and home environment with the development of wheeze and asthma. METHODS: We conducted a cross-sectional survey of 969 elementary school students. Data included questions about asthma and wheeze symptoms, exposure to tobacco smoke, and home environment including history of moving into a new house within 1 year of age after birth, use of fragrance at home, recent purchase of new furniture. Logistic regression and Pearson chi statistics were used to estimate these associations. RESULTS: ETS exposure was associated with current wheeze and nocturnal sleep disturbance. Paternal smoking over 20 cigarettes per day was associated with 4 or more episodes of wheeze during the past 1 year. However, there were no significant differences in pulmonary function, serum total IgE levels, blood eosinophil counts, and atopy between children with ETS exposure and non-exposure. Moving into a new house within 1 year of birth was associated with current asthma or wheeze. Use of fragrance at home and purchase of new furniture during the past 1 year were associated with current wheeze, current physician-diagnosed asthma, and nocturnal cough. CONCLUSION: Exposure to ETS, moving into a new house after birth, and indoor fragrance are risk factors for wheeze and asthma in schoolchildren.

BACKGROUND: Although the pro-convulsant or anticonvulsant properties of propofol remain a matter of controversy, it is evident that propofol can produce involuntary movement. Such movement is a relatively common side effect, especially in children, and may be dose-related or injection rate-related. The goal of this study was to evaluate the effect of injection rate upon involuntary movement during propofol induction in children. METHODS: Children (age 3-14 yr) undergoing elective Eye and ENT surgery were randomly allocated to one of 4 groups based on the propofol injection rate (A, manual/15 s; B, 360 ml/hr; C, 200 ml/hr, D, 100 ml/hr) using a manual injection method and syringe pumps. No premedication was used. The induction dosage of propofol was 3 mg/kg in all groups. Fentanyl 1mcg/kg and 1% lidocaine 1-2ml were given I.V. before propofol. Involuntary movement was graded 0-2 on severity. The infused dose of propofol at movement was measured. Movement due to pain or mask fitting was not regarded as an involuntary movement. All results were analyzed using the Chi-Square Test and ANOVA. RESULTS: 595 children were studied. Age, gender, and weight were similar in the 4 groups. Involuntary movements were apparent in 179 (30.1%) of the 595 subjects. Movements were significantly less in group A (12.4%) and B (16.4%) compared to group C (46.6%) and D (45.3%). The grades of movement were not different among the 4 groups. The durations of movement in group A and B were significantly short compared to group C and D. The infused dose of propofol (mg/kg) at movement was higher in group C (2.65+/-0.62) than in A (1.99+/-0.62) and B (2.43+/-0.78). There were no significant hemodynamic and SPO2 changes during and after the propofol injection. CONCLUSIONS: We concluded that slow injection may increase the incidence of involuntary movement during propofol induction in children. Since the bolus injection rates are usually slow in most syringe pumps, manual injection for 10 15 s may be a better choice for smoother induction, as it requires fewer interventions to prevent venous catheter displacement in children.

PURPOSE: There were no accurate data of hematologic changes in the high school students in Korea since 1980'. Because of rapid growing of Korean students recently, it is necessary to reevaluate Korean data. So we compared hematologic changes in the students of general (GHS) and athletic high school (AHS) in Seoul city. METHODS: We reassured red cell count (RBC), hemoglobin (Hb), hematocrit (Hct), and related hematologic factors in the 452 GHS (male 290, female 162) as control group and the 138 AHS (male 70, female 68) as exercised group. Hematologic comparisons were performed between the students of AHS and GHS and the male and female students with t-test. RESULTS: 1) Values of RBC, Hb, Hct, MCHC, RDW were 4.6+/-0.3x1012/L, 13.4+/-1.2g/dL, 41.5+/- 3.4%, 32.2+/-0.5g/dL, 12.1+/-0.9% respectively in the male AHS and 5.2+/-0.3x1012/L, 15.2+/- 1.0g/dL, 46.7+/-3.0%, 32.5+/-0.5g/dL, 12.3+/-0.6% respectively in male GHS, and there were significant between compared data. 2) Values of RBC, Hb, Hct MPV were 4.5+/-0.3x1012/L, 13.6+/-1.2g/dL, 40.5+/-3.2%, 9.0+/- 0.6fl respectively in the female AHS and 5.0+/-0.5x1012/L, 14.9+/-1.3g/dL, 44.8+/-3.4%, 8.7+/- 0.8fl respectively in the female GHS, and significance were between compared data. 3) Values of MCH, MCHC, RDW, MPV were 30.1+/-1.8pg, 33.6+/-1.1g/dL, 12.8+/-1.1%, 9.0+/-0.6fl respectively in the female AHS and 29.3+/-1.8pg, 32.2+/-0.5g/dL, 12.1+/-0.9%, 8.7+/-0.9fl respectively in the male AHS, and there were significant between compared data. 4) Values of RBC, Hct, MCH, MCHC, RDW, PLT were 5.0+/-0.5x1012/L, 44.8+/-3.4%, 30.0+/-2.1pg, 33.4+/-1.1g/dL, 12.7+/-1.0%, 29.8+/-5.8x104/mm3 respectively in the female non-AHS, and 5.2+/-0.3x1012/L, 46.7+/-3.0%, 29.4+/-1.4pg, 32.5+/-0.5g/dL, 12.3+/-0.6%, 28.7+/- 5.8x104/mm3 respectively in the male non-AHS, and there were significant between compared data. CONCLUSIONS: Among the high school students, exercise caused several hematologic changes that were significant decline of the values of RBC, hemoglobin, hematocrit compared to control group regardless of sex. In female students, their values of MCH, MCHC, RDW were significantly increased compared to male students regardless of exercise.

Tyrosinemia type 1 is an autosomal recessive inborn error of tyrosine metabolism that caused a mutation in the gene coding for the enzyme fumarylacetoacetate hydrolase(FAH). As a result, maleylacetoacetate(MAA) and fumarylacetoacetate(FAA) are formed. The accumulated FAA is converted into succinylacetone(SA) and succinylacetoacetate(SAA) which are excreted in urine. The first report with typical clinical and biochemical findings was presented by Sakai in 1957. Clinically, the disorder is characterized by progressive liver damage with liver failure, a high risk of hepatocellular carcinoma and renal tubular dysfunction hypophosphataemic rickets. Some patients have porphyria-like episodes. Liver transplantation has been the ultimate treatment of tyrosinemia. However pharmacological therapy with 2-(2-nitro-4-trifluoromethylbenzoyl) -1,3-cyclohexanedione(NTBC) has offered a new therapeutic option in addition to dietary restriction of tyrosine and phenylalanine. We experienced a case of tyrosinemia type 1 with cytomegalovirus infection in a 4-month-old male who improved by dietary restriction of tyrosine and phenylalanine.
