PURPOSE: Childhood headache is different from adulthood headache and according to their age in clinical aspects. This study investigated the clinical differences of primary headache according to ages of children and adolescents. METHODS: A 300 children who did not show abnormalities on neurologic examination or brain CT or MRI were classified into two groups according to their ages. RESULTS: The percentage of those in the migraine group (24.2% vs. 35.9% in Groups 1 and 2 respectively) was higher in Group 2, but it was not statistically significant. In relation to the duration of headache, pain lasting for less than one hour accounted for 59.8% and 40% in Groups 1 and 2, respectively (P=0.001). In relation to the location headaches developed, the frontal region (40.2%) and temporal region (48.1%) were the most common in Groups 1 and 2, respectively (P<0.001). In relation to the nature of the headaches, tightening sensation accounted for the highest percentage in both groups; however, pulsating sensation were more common in Group 2 than in Group 1 (16.2% vs. 8.3%, P=0.038). In relation to the severity of headaches, severe to profound headaches accounted for 35.5% and 61.1% in Groups 1 and 2, respectively (P<0.001). In relation to laterality, unilateral headaches accounted for 12.4% and 26.7% in Groups 1 and 2, respectively (P=0.002). In relation to accompanying symptoms, the incidence of photophobia was higher in Group 2 than in Group 1 (P=0.047). CONCLUSION: Age factors should be considered in the diagnosis of childhood headaches. Also, we consider that there may be a need to establish diagnostic criteria specifically for childhood headaches separately from those for adulthood headaches.

Nutritional rickets, which is caused by deficiency of calcium or vitamin D, is a rare disease in developed countries. However some cases have been reported recently, that developed as a result of a restricted and nutritionally imbalanced diet due to atopic dermatitis and related food allergy. We treated two infant cases of nutritional rickets. The infants had suffered from atopic dermatitis, and were fed "Sun-sik" (a powdery mixture of several grains and fruits) without receiving cow's milk or any milk products in their diet. After an adequate supply of calcium and nutritional management, they were markedly improved.

Adult onset Stills Disease (AOSD) is a systemic inflammatory disease characterized by spiking high fevers, arthritis, and an evanescent rash. Although many patients respond to nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroid, some patients fail to do so or are found to be resistant and require high doses of corticosteroid which induce severe side effects. Recently, treatment with intravenous immunoglobulin (IVIG) has been reported to be effective in patients with AOSD who were refractory to NSAIDs. Here, we report a case of AOSD treated with IVIG with a review of the literature.

Objective and METHOD: In order to identify the aggravating agents for intrinsic asthma, we performed ASA- and food additive-challenge tests on 182 subjects diagnosed as having intrinsic asthma. The following tests were performed: Lysine-aspirin bronchoprovocation test to confirm aspirin-sensitivity, sodium bi-sulfite (40-200mg) oral provocation test for sulfite sensitivity, tartrazine oral provocation test (50mg) for tartrazine sensitivity, and sodium benzoate (400mg) oral provocation test for sodium benzoate sensitivity. Positive reaction was defined as decrease in FEV, by more than 20% from the baseline value after the provocation. RESULT: Seventy-five (41.2%) of 182 subjects showed positive responses to more than one agent among the aspirin and three food additives challenged. The prevalence of aspirin-sensitivity was the highest (22.5%), followed by sulfite-sensitivity (8.8%), and then concurrent sensitivity to both aspirin and sulfite (6.0% ), to both aspirin and tartrazine (1.6% ), to aspirin, sulfite and tartrazine (1.1%) and to aspirin, sulfite and sodium benzoate (0.5%). Rhino-sinusitis was noted in 62.5% of aspirin-sensitive asthmatic subjects, 60% of sulfite-sensitive ones, and 80% of tartrazine-sensitive ones. Urticaria was noted in 21.4% of aspirin-sensitive asthmatic subjects, 16.6% of sulfite-sensitive ones and 6.3% of tartrazine-sensitive ones. Thirty-seven to 83% of positive responders had no adverse reaction history. CONCLUSION: These findings suggest that ASA and food additive challenge tests should be considered as a screening test to evaluate any aggravating factors in subjects with intrinsic asthma, even though they may not have experienced any adverse reactions.

BACKGROUND: There has been no reported case of arsine poisoning in Korea so far. This article presents the first reported case of arsine poisoning with hemolytic anemia accompanied by acute renal failure. Initially we suspected an infectious agent to be the cause of this case but later discovered that it was arsine poisoning suffered while working at a zinc-smelting industry in the process of recovering the cadmium by-product. We report this case and discuss the arsine poisoning. CASE REPORT: A 27-year-old man employed at a zinc-smelting industry was exposed to arsine while working in the process to recover the cadmium by-product.On the 4th day at work, he had to redissolve defected by-product into a pot and began to experience febrile sensation, diarrhea, upper quadrant abdominal pain, jaundice, and anorexia.After he was admitted to a hospital, the laboratory results showed hemolytic anemia, acute renal failure and elevated concentration of arsenic. He was thus diagnosed as suffering from arsine-poisoning and underwent hem dialysisand supportive therapy.He recovered from the poisoning after51 days and was discharged from the hospital. DISCUSSION: When workers dealing with arsenic-containing material present with hematuria, nausea, vomiting, abdominal pain, and dyspnea followed by hemolysis with acute renal failure, arsine poisoning must be suspected and diagnosis followed by treatment must commence immediately. If any future cases occur, blood and urine samples should be kept in storage so any necessary analysis can be processed later.

BACKGROUND: Longer needle and complicated insulin injection technique such as injecting at a 45-degree angle and making skinfolds may decrease patient compliance to insulin injection therapy. In this light, shorter insulin needles have been recently developed. However, it is necessary to ascertain that such shorter needles are appropriate for Korean patients with diabetes as well. METHODS: First, the diverse demographic and diabetic features of 156 Korean adults with diabetes were collected by a questionnaire and a device unit of body fat measurement. The skin and subcutaneous fat thicknesses of each subject were measured by Ultrasound device with a 7- to 12-MHz probe. Data were analyzed using analysis of variance and multiple linear regression. RESULTS: The mean skin thickness was 2.29+/-0.37 mm in the abdomen and 2.00+/-0.34 mm in the upper arms, and the mean subcutaneous fat thickness was to 10.15+/-6.54 mm in the abdomen and 5.50+/-2.68 mm in the upper arms. Our analysis showed that the factors affecting the skin thickness of the abdomen and upper arms were gender and body mass index (BMI), whereas the factors influencing the subcutaneous fat thickness in the abdomen were gender and BMI, and the factors influencing the subcutaneous fat thickness in the upper arms were gender, BMI, and age. Insulin fluids may not appear to be intradermally injected into the abdomen and upper arms at any needle lengths. The risk of intramuscular injection is likely to increase with longer insulin needles and lower BMI. CONCLUSION: It is recommended to fully inform the patients about the lengths of needles for insulin injections. As for the recommended needle length, the findings of this study indicate that needles as short as 4 mm are sufficient to deliver insulin for Korean patients with diabetes.

OBJECTIVES: The prevalence of hepatitis A decreases with improved hygiene and changing lifestyle. However, hepatitis A remains a global problem causing sporadic food-borne infections. Over the past 5 years, hepatitis A incidence has increased, and 15 deaths were reported in 2009 in Korea. Concerns about hepatitis A infection have increased. We checked hepatitis A virus antibody (HAV anti-IgG) in a large manufacturing company, so that the results could be a guideline for workplace preventive plan and health policy for hepatitis A. METHODS: We investigated the seroprevalence of HAV anti-IgG and the demographic characteristics of employee volunteer, in a company in Ulsan. In addition, we estimated those factors that affected seroprevalence of HAV anti-IgG. RESULTS: A total of 2,719 employee volunteers were enrolled into the study. The seropositive rate of HAV anti-IgG was 69.8% (n=1,899) and, the seronegative rate was 30.2% (n=820). There were no enrolled employees under age 24 years who tested positive for HAV anti-IgG; in this group, the seropositive rate was 0.0% (n=0); in 25~29 years the rate was 3.9% (n=12) and 26.5% (n=118) in 30~34 years olds. In the 35-39 ears, 61.1% (n=203) tested HAV anti-IgG positive and 86.8% (n=256) of 40~44 years tested positive. Other group tested as follows: 96.5% (n=335) in 45~49 year olds, 98.7% (n=593) in 50~54 year olds, and 100% (n=382) in over 55 years. There was a significantly increasing tendency to test HAV anti-IgG positive according to age group. In the 34-35 year olds, the seropositive rate exceeded the seronegative rate. CONCLUSIONS: HAV anti-IgG seropositive rate increased according to age. The result can used for guideline recommendationsand establishing hepatitis A policies.
