In pediatric ages, the supracondylar fractures of the humerus are common and often associated with complications. In these days, the serious complications were reduced with a lot of apprehension for the treatment. While the fracture itself was healed properly, the remained deformity was frequent and it was known that this deformity was derived not from growth disturbance after fracture but from inaccurate reduction at the time of initial reduction. We have performed an anatomical study. Identical skeletal models were osteotomized at the supracondyle of the humerus and every combination of 0°,10°, 20°, 30° of each of varus, valgus tilt, internal rotation and flexion were tried at osteotomized site and were taken radiography and photographed. We measured T-C angle, carrying angle and displacement of distal radial styloid process on X-ray. We got the results as follow. 1. Simple rotational deformity of 50° have resulted in only 20% decrease of width of distal osteotomized surface in AP films in pure rotational deformity. 2. Flexion at the osteotomized site have no specific effect on the change of varus and valgus deformity. There were remarkable increase from 0° to 20° after then the changes were decreased in varus tendency according to internal rotation. 3. Among the changes of varus and valgus angle, the varus deformity was largest at the change of angle from 0° to 10° and other change of angle of varus and valgus deformity were incrersed at similar degree. 4. At the osteotomy site, without changes of varus and valgus angle, it showed that internal rotation resulted in varus defromity.

PURPOSE: Vigabatrin is a widely used antiepileptic drug that greatly increases whole brain gamma- aminobutyric acid(GABA). But little is known about the anticonvulsant effect of vigabatrin on pilocarpine-induced seizures in the immature rats. This study was conducted to determine the effects of vigabatrin on pilocarpine-induced seizures in the immature rats. METHODS: Six to eight day old Sprague-Dawley rats were classified into control(n=5) and vigabatrin-treated(n=5) groups that were pretreated with 30mg/kg of vigabatrin. Animals received vigabatrin or saline, intraperitonealy, for 6 days, once a day. And on the 5th day, right and left cortical electrodes were placed in 10-14 day old animals using stereotaxic instrument. The following day 2.5-hour EEG recordings were obtained to monitor the latency to first electrographic seizures and to first status epilepticus induced by intraperitoneal injection of pilocarpine(200mg/kg). Data were analyzed using the log-rank test. RESULTS: Electrographic seizures and status epilepticus were seen in 80% of vigabatrin-treated group, and in 100% of control group rats. And the latency to first seizure was 8.8+/-2.0 minutes in control group and 20.5+/-5.2 minutes in vigabatrin-treated animals(P<0.02), and to status epilepticus was 12.2+/-1.2 minutes in control group and 29.3+/-6.3 minutes in vigabatrin-treated group(P<0.03). CONCLUSION: It was confirmed that 30mg/kg of vigabatrin administration for 6 days did not affect the body weight gain and behavior of immature rats and had an anticonvulsant effect. These findings might demonstrate that the prolonged latency to seizure, and to status epilepticus, was a time to reduce GABA that was elevated in the brain by vigabatrin administration below the seizure threshold, by pilocarpine.

BACKGROUND: Clinical trials have shown that b-adrenergic blocking drugs are effective and well tolerated in patients with mild to moderate congestive heart failure. Carvedilol is a mild b1-selective adrenergic blocking agent with vasodilating properties due to a blocker and antioxidant and anti-proliferative properties. This study assessed the efficacy and safety of carvedilol in patients with moderate to severe congestive heart failure caused by idiopathic dilated cardiomyopathy. METHODS: We enrolled 27 patients with moderate to severe congestive heart failure with a left ventricular ejection fraction of 35% by MUGA scan. Each patient was randomly assigned to either control (n-9) or carvedilol (n-18, target dose 25 mg bid) for 6 months while background therapy with digoxin, diuretics, and ACE inhibitor remained constant. RESULTS: Compared to the control group, patients in the carvedilol group showed significant increase of left ventricular ejection fraction (p<0.05). In addition, patients in the carvedilol group had a tendency to show a decrease in left ventricular end-diastolic dimension and heart rate. Also, the carvedilol group had a greater frequency of symptomatic improvement than the control group. There was neither serious side effects nor hospitalization. CONCLUSION: These finding indicate that carvedilol produces important clinical benefits in patients with moderate to severe heart failure treated with digoxin, diuretics, and ACE inhibitor without serious side effects.

PURPOSE: Obesity is a frequent nutritional disorder in children and adolescent and its prevalence is increasing. Bioelectrical impedance analysis is a simple, rapid, non-invasive and reproducible technique. The aim of this study was to measure percent of body fat using bioelectrical impedance in healthy children. METHODS: We measured height, weight and bioelectrical impedance in 1035 children aged 7-18 years(496 males and 539 females). RESULTS: Percent of body fat was decreased in male children, but it was increased during the pubertal period in female. 95th percentiles of percent of body fat by bioelectrical impedance was 32.9% in 7 year olds, 31.6% in 8, 34.7% in 9, 35.1% in 10, 35.8% in 11, 33.1% in 12, 36.1% in 13, 38.2% in 14, 33.3% in 15, 28.3% in 16, 32.8% in 17 and 32.2% in 18 year olds for males. 95th percentiles of percent of body fat by bioelectrical impedance was 25.1% in 7 year olds, 29.6% in 8, 30.5% in 9, 35.6% in 10, 34.5% in 11, 36.5% in 12, 39.1% in 13, 34.1% in 14, 33.7% in 15, 32.8% in 16, 34.5% in 17 and 35.1% in 18 year olds for females. Intraobserver reliability coefficient of bioelectrical impedance analysis was 0.995 and intraobserver reliability of BI(Bioelectrical impedance) analysis was significantly high. CONCLUSION: To measure body fat percentage using bioelectrical impedance analysis in healthy children provides objective data in diagnosing obesity.

Intravenous immunoglobulin (IVIG) is being increasingly used to treat numerous immune-mediated diseases. However, there is a paucity of knowledge on the specific mode of action of IVIG in vivo. In this study, the in vitro effects of IVIG on peripheral blood mononuclear cell (PBMC) proliferation using phytohemagglutinin (PHA), anti-CD3 monoclonal antibody (MAb), phorbol myristate acetate (PMA), or purified protein derivatives (PPD) have been analyzed. The PBMCs were obtained from more than 10 individual donors. In all cases, IVIG almost completely inhibited PBMC proliferation at concentration above 20 mg/mL except when used in conjunction with PMA. PHA-induced proliferation of PBMCs at concentrations ranging from 1 to 15 mg/mL did not show significant differences. Anti-CD3 MAb-induced proliferation showed dose-dependent inhibition at concentrations ranging from 1 to 10 mg/mL. Interestingly, PMA-induced proliferation of PBMCs showed a dose-dependent increase at the same concentration range. PPD-induced proliferation of PBMC at concentrations ranging from 1 to 10 mg/mL did not show any statistically significant differences. These results suggest that high dose IVIG may be necessary to immune modulation in vivo and IVIG has various effects on PBMCs proliferation in limited concentration in vitro.

Drug-induced agranulocytosis is a potentially lethal disorder characterized by selective neutropenia. G-CSF has been utilized for its treatment. We report a case of acute agranulocytosis probably associated with injection of sulpyrine(dipyrone). A three-year old girl was admitted to Taejon St. Mary's Hospital following five days of fever and two days of chills and prostration. During this period, she had been treated at local clinics with oral acetaminophen, ibuprofen, and miokamycin. Two days before admission, she was administered an intramuscular injection of dipyrone as antipyretics. She had a past history of previous sensitization of dipyrone. CBC revealed profound netropenia(total WBC 900/mm3, with 1% neutrophils, 88% lymphocytes, 10% atypical lymphocytes, 1% monocytes), but normal RBC and platelet count. Bone marrow examination showed hypocellularity(20%), decreased myeloid precusors, and M:E ratio of 1 : 2.5. The girl received subcutaneous G-CSF once daily for 3 days. G-CSF therapy resulted in a steep increase of neutrophil count, which was faster than the spontaneous recovery reported in the literature. G-CSF may be considered useful in the management of drug-induced agranulocytosis.

Common variable immunodeficiency (CVID) is a heterogeneous collection of disorders with hypogammaglobulinemia with recurrent bacterial infections and high incidence of autoimmune disorders as its hallmark. We report a 7-year-old girl suffering from CVID with Coombs' test positive hemolytic anemia. She had been relatively well until 23-months old when she was admitted to Taejon St. Mary's Hospital with pneumonia 5 years ago. Afterwards, she had suffered from recurrent otitis media, paranasal sinusitis, bronchitis and pneumonia, experiencing 13 admissions. She was diagnosed as autoimmune hemolytic anemia at 4-years old and had been treated with prednisolone. Laboratory finidings showed hypogammaglobulinemia(gamma-globulin in immunoelectrophoresis 0.04g/dL, IgG 170mg/dL, IgA 31mg/dL, IgM 27.5mg/dL) which was previously within normal limits checked at the age of 3- and 5-years old. Isohemmagglutinins (Anti-A,-B IgM and IgG) and anti-measles IgG, anti-mumps IgG, anti-rubella IgG and anti-HBs antibody along with PPD skin test were all negative. Peripheral lymphocyte subsets revealed as follows : pan T cells (CD3+) 48.6% (normal values : 60-85%), pan B cells (CD19+) 36.7% (8-20%), CD4+ T cells 24.4% (28+/-8%), CD8+ T cells 15.3% (5+/-10%), and CD4/CD8 ratio of 1.6 (0.6-2.8). Proliferations of peripheral blood mononuclear cells induced by various T cell stimulants were all markedly depressed. Chronic paranasal sinusitis and lung parenchymal damages were revealed on computerized tomography and lung scan, and a monthly intravenous immunoglobulin therapy was started.

PURPOSE: To characterize the MR findings of nontumorous focal low attenuated areas around the falciformligament on contrast enhanced CT scan. MATERIALS AND METHODS: MR was used to study twelve patients who oncontrast-enhanced CT scan showed focal low attenuated areas around the falciform ligament. Imaging was carried outwith T1, FSE-T2, fat-suppressed T1, and fat-suppressed FSE T2-weighted pulse sequences at 1.5 T. Dynamic fastlow-angle shot(FLASH) imaging was performed in seven patients and chemical shift images were obtained in five. The findings on contrast enhanced CT scan were compared with those on MR. RESULTS: In five cases, the lesions were slightly hyperintense on T1 and FSE T2-weighted images, hypointense on fat-suppressed images, hyperintense on in-phase image, and presented a considerably diminished signal intensity on opposed-image. Focal hypointensity areas were visualized at 50-75 sec after contrast enhancement in three cases in which a lesion was not depicted oneither T1-or FSE T2-weighted images. CONCLUSION: Nontumorous focal low attenuated areas around the falciformligament were shown on MR imaging as focal fatty infiltrations or pseudolesions.
