Obesity has been implicated as a significant risk factor for multiple medical condition including hypertention, glucose intolerance, hyperlipidemia, hyperinsulinemia and fatty liver. Furthermore, obesity in childhood is believed to be a reliable predictor of a similar condition in adulthood. During the recent years, there has been a rapid rise in the incidence of childhood obesity in Korea due to increased dietary intake rich in caloric content. This study was undertaken to investigate the epidemiology and potential health complications of obesity observed in elmentary school students. A total of 3,103 children (1630 boys and 1,473 girls), ages ranging from 6 to 12, were studied with personal interview, physical examination, and laboratory evaluation. The results were as follows: 1) The prevalence of obesity was 13.44% with approximately equal distribution among boys (14.42%) and girls (12.36%). 2) The prevalence of childhood obesity in Seoul was significantly higher (18.62%) than that in Suwon (7.85%) and in Hongchon (6.02%). 3) A higher incidence of hypertension was dectected in obese subjects and this was more obvious in girls. 4) Hyperlipidemia and elevated Atherogenic Index were more frequently observed in obese group. 5) although fasting blood glucose levels were similar in both groups. AST and ALT abnormalities were much more prevalent in obese group. It is concluded that hypertension and other metabolic abnormalities are much more frequently observed in obese children and that our effects should be focused on the earliest dection, prevention and management of childhood obesity.

The hyperimmunoglobulin E syndrome is a primary immunodificiency disorder characterized by recurrent staphylococcal infections and markedly elevated serum IgE level. Clinical features are coarse face and severe infections of the skin-furunculosis or chronically pruritic dermatitis and sinopulmonary tract infection from infancy by coagulase positive Staphylococcus aureus, or Candida albicans etc. The patients's serum IgE level is elevated but the basic immunologic pathogenesis not fully understood. We have experienced a case of hyperimmunoglobulin E syndrome in a 26/12-year-old who had suffered from recurrent staphylococcal pneumonias and abscesses and chronically pruritic dermatitis from 1 month of age with elevated serum IgE level. A brief review of the related literature is presented.

A 63-year-old male who had subtotal gastrectomy for early gastric cancer three months ago underwent Tc-99m bone scintigraphy for the evaluation of skeletal metastases. He had no symptoms such as fever, tenderness, or wound discharge. On physical examination, the surgical scar along the midline of the upper abdomen had keloid formation and there was no radiographic evidence of calcification. Bone scintigraphy (Fig. 1A & 1B) demonstrated an unusual linear increased uptake along the midline of the upper abdomen that corresponded to the skin incision for subtotal gastrectomy. Usually, an incisional scar will not be visualized in Tc-99m methylene diphosphate (MDP) scintigraphy beyond two weeks after surgery.1) Upon reviewing the literature, there were only a few reports where localization of Tc-99m MDP in surgical scars were found two months after surgery.2) It was also reported that a few cases with Tc-99m MDP uptake in the keloid scar developed after surgery. Although there are several potential mechanisms that may explain the uptake of Tc-99m MDP in scar tissue, the primary mechanism in older scars is suggested to be a result of pathological calcification.2) Siddiqui et al3) suggested it could be due to microscopic calcification in small resolving hematomas. However, the primary mechanism in keloid scar is not well-known. We should obtain oblique or lateral views to differentiate the uptake in healing surgical scars from the artifactual uptake.

A 60-year-old male with carcinoma of the prostate and cerebral infarction underwent a Tc-99m MDP bone scintigraphy for the evaluation of skeletal metastases. Bone scintigraphy (Fig. 1) showed multiple areas of increased uptake of Tc-99m MDP in the skull, spine, and ribs representing skeletal metastases. Two different patterns of uptake occurred in the skull region (Fig. 1A-C); one represents bony metastasis and the other represents cerebral infarction. The shape, size, location, intensity, and border of the increased uptake differed between the two lesions. An oval-shaped pattern with smaller size, greater intensity and more sharply defined border in the frontal region was consistent with bony metastasis. A rectangular-shaped pattern with larger size, lesser intensity and relatively indistinct border in the temporo-parieto-occipital region was consistent with cerebral infarction. Increased uptake of bone-seeking radiotracers in cerebral infarction has been reported previously.1-4) A suggested mechanism by which bone-seeking radiotracers accumulate in the necrotizing cerebral tissue is an alteration of the blood-brain barrier induced during cerebral infarction, which results in entry of the radiotracers into the extracellular space of the brain.4) Brain CT (Fig. 2) performed 7 days before and one month after the bone scintigraphy revealed lesions on the right temporo-parieto-occipital region consistent with acute hemorrhagic and chronic cerebral infarction, respectively.

BACKGROUNDS: This study was performed to determine the onset time and dose of intranasal midazolam used for preanesthetic sedation in children. METHODS: The children were randomly allocated to recieve one of three medications via the nasal route in a double blind manner. Group I: patients were given normal saline 0.2 ml/5kg, Group II: patients were given midazolam 0.2 mg/kg, Group III: patients were given midazolam 0.3 mg/kg. RESULTS: The cardiovascular and SpO2 changes were not significantly different among the patients of the three groups. The sedation score was greater in group II compared with group I from 5 minute after administration (1.9 vs 2.7, p<0.05). postanesthetic recovery score (PARS) was not significantly different among the three groups. CONCLUSIONS: It is suggested that intranasal midazolam (0.2 mg/kg) produces anxiolysis and sedation in children with rapid onset.

PURPOSE: The ureteral stent is very effective for the drainage of urine and maintenance of renal function in patients with ureteral strictures. Retrograde ureteral stunting is a common procedure. However, there is a need for antegrade ureteral stunting with percutaneous nephrostomy in cases of severe ureteral strictures. In these cases, retrograde exchange of ureteral stent is very difficult. Hence, we tried an easier and more efficient exchanging method available in these cases and also assessed its clinical results. MATERIALS AND METHODS: We performed retrograde ureteral scent exchange In the patients using the following procedure. First, the distal tip of the previously Inserted ureteral stunt was pulled out 2cm beyond the external meatus. Second, a guide-wire was inserted into the scent through the hole upto the kidney and then the stunt was completely removed. Third, a cystoscopic sheath without obturator was introduced into the bladder passing over the guide-wire. Fourth, a new ureteral stent was introduced into the ureter over the guide-wire with pusher. RESULTS: We experienced successful exchange of ureteral steno 95 times on 9 ureters in 8 patients with severe ureteral strictures who had antegrade ureteral stenting performed. CONCLUSIONS: From these results, we conclude that this exchanging method is very safe and effective.
