5.Correlation of Measurements for Body Fat in Obese Children.
Korean Journal of Pediatrics 2004;47(5):485-490
PURPOSE: Measurement of body fat in obese children is useful not only in evaluating health hazard but also in establishing standards of treatment and evaluating the effectiveness of treatment. In the field of clinical and laboratory study, there are various methods with different reliability, propriety, convenience, and expenses. However, the practical value of these studies is limited in Korea, especially in the field of pediatrics, therefore we investigated the correlation of body fat measurement methods to establish the basis for the practical use in children. METHODS: The study is based on the records of a total of 32 cases who visited the pediatric obesity clinics at Chung-Ang University Yong San Hospital from April 2003 to September 2003. We measured the height, weight, waist-hip ratio obesity degree and body mass index. Then we analyzed the correlation of these manual measurement data with the results of bioelectrical impedance analysis(BIA), Dual energy X-ray absorptiometry(DEXA). RESULTS: The body mass index was correlated with the quantity of body fat(r=0.805, P=0.000), the ratio of body fat(r=0.437, P=0.012), and the ratio of abdominal fat(r=0.458, P=0.008) in DEXA. The obesity degree was correlated only with the ratio of body fat(r=0.358, P=0.044) in DEXA. The body composition measured by BIA and DEXA showed significant correlation with the quantity of body fat(r=0.953, P=0.000) and the ratio of body fat(r=0.578, P=0.001), but the ratios of abdominal fat were not correlated with each other. CONCLUSION: Body mass index is more accurate compared with obesity degree. In addition, BIA can be utilized competitively in screening of body fat, although it is limited in measuring localized fat distribution when compared with DEXA.

BACKGROUND: In patients with mitral stenosis, the degree of pulmonary hypertension is expected to be related to the severity of mitral valve obstruction. However, some patients with severe mitral stenosis do not develop reactive pulmonary hypertension. MATERIALS AND METHODS: We evaluated 34 patients with symptomatic mitral stenosis undergoing percutaneous mitral valvuloplasty by clinical, echocardiographic, and invasive hemodynamic(cardiac cathrterization) data. Prevalvuloplasty data were available in 34 subjects[mean age 38+/-9 year ; women 74% ; NYHA class 1 (6 patients), class 2 (17 patients), class 3 (7 patients), class 4 (4 patients) ; in electrocardiography, NSR(23 patients), Atrial fibrillation(11 patients)]. RESULTS: 1) The pulmonary vascular bed gradient was significantly correlated with pulmonary vascular resistance(r=0.91), mean pulmonary artery pressure(r=0.82), transmitral mean pressure gradient(r=0.64) and mitral valve area(r=-0.48). The pulmonary vascular resistance was significantly correlated with mena pulmonary artery pressure(r=0.77), transmiral mean pressure gradient(r=0.61) and mitral valve area(r=-0.54), NYHA functional classification(r=0.36). However, the pulmonary vascular bed gradient and pulmonary vascular resistance was not significantly correlated with age, sex, cardiac output, the severity of mitral regurgitation and mean left atrial pressure. 2) The mean pulmonary artery pressure was significantly correlated with mean left atrial pressure(r=0.80), transmitral mean pressure gradient(r=0.72) and mitral valve area(r=-0.47). 3) When patients were divided into those with a pulmonary vascular bed gradient > 12mmHg and = 12mmHg, the two groups were significantly different for many of these measures-Pulmonary vascular resistance(p=0.004), mean pulmonary artery pressure(p=/p<0.0001), transmitral mean pressure gradient(p=0.008), mitral valve area(p=0.04). 4) The mean left atrial pressure was significantly correlated with mean pulmonary artery pressure but not with pulmonary vascular resistance and pulmonary vascular bed gradient as the index of reactive pulmonary hypertension. 5) Results of multiple regressin analysis of factors affecting pulmonary vascular bed gradient showed that transmitral mean pressure gradient was the most significant factor(op<0.0001). 6) The decrease in mean pulmonary artery pressure from immediate before to immediate after balloon commissurotomy was related to pulmonary vascular resistance(r=0.51), pulmonary vascular bed gradient(r=0.63), mean left atrial pressure(r=0.60), transmitral mean pressure gradient(r=0.50), mitral valve area(r--0.41). CONCLUSION: In patients with mitral stensis, the degree of reactive pulmonary hypertension was significantly related to the severity of mitral stenosis(transmitral mean pressure gradient, mitral valve area) but not to mean left artial pressure. In some patients the degree of mitral stenosis could not expect the development of reactive pulmonary hypertension. It is suggested that specific predictors of pulmonary hypertension on an individual patient cannot be identified based solely on the severity of mitral valve disease and must include many factors associated with pulmonary parenchymal diseases, other heart diseases, and duration of mitral stensis.

Scrotal swelling may be acute or chronic, painful or painless. Common causes of scrotal swelling in newborns are hydrocele, inguinal hernia, testicular torsion, testicular tumor, scrotal hematoma, meconium peritonitis and epididymitis. Abrupt onset of a painful scrotal swelling necessitates prompt evaluation. Testicular torsion and incarcerated inguinal hernia require urgent surgical management. We report a case of scrotal swelling caused by a tunica vaginalis abscess in a 20-days-old boy. He was admitted to the hospital due to fever, irritability and left scrotal swelling with local heat, tenderness and redness. Exploratory laparotomy was performed to rule out testicular torsion. On the operative field, congestive erythematous inflammation on the left tunica vaginalis was noted and it was filled with a pus like discharge. The cultured organism was Streptococcus agalactiae(group B). He recovered quickly after debridement and administration of empirical antibiotics.

To elucidate iron utilization patterns of Staphylococcus aureus according to the growth, we checked the residual iron concentration and the production of siderophores at the indicated times while culturing S. aureus ATCC 6538 and 25923 strains in brain heart infusion broth. By using streptonigrin susceptibility test and investigating growth curves in three culture media of which iron concentration is 0.2, 20, 45 uM, respectively, we found out that iron metabolism of 6538 strain was more active than that of 25923 strain. In point of tendency of iron consumption, 6538 strain steeply consumed iron just before the onset of stationary phase, but 25923 strain did gradually iron throughout the growth phase. Nevertheless, total amount of iron consumed by each strain during the growth was almost no difference between the strains. CAS diffusion assay in detecting siderophores showed that siderophore production followed iron consumption. These results suggest that the siderophores play significant role in iron utilization in vitro.

BACKGROUND/AIMS: We examined the effects of cilostazol on mitogen-activated protein kinase (MAPK) activity and its relationship with cilostazol-mediated protection against apoptosis in lipopolysaccharide (LPS)-treated endothelial cells. METHODS: Human umbilical vein endothelial cells (HUVECs) were exposed to LPS and cilostazol with and without specific inhibitors of MAPKs; changes in MAPK activity in association with cell viability and apoptotic signaling were investigated. RESULTS: Cilostazol protected HUVECs against LPS-induced apoptosis by suppressing the mitochondrial permeability transition, cytosolic release of cytochrome c, and subsequent activation of caspases, stimulating extracellullar signal-regulated kinase (ERK1/2) and p38 MAPK signaling, and increasing phosphorylated cAMPresponsive element-binding protein (CREB) and Bcl-2 expression, while suppressing Bax expression. These cilostazol-mediated cellular events were effectively blocked by MAPK/ERK kinase (MEK1/2) and p38 MAPK inhibitors. CONCLUSIONS: Cilostazol protects HUVECs against LPS-induced apoptosis by suppressing mitochondriadependent apoptotic signaling. Activation of ERK1/2 and p38 MAPKs, and subsequent stimulation of CREB phosphorylation and Bcl-2 expression, may be responsible for the cellular signaling mechanism of cilostazolmediated protection.

Journal of the Korean Neurological Association 1998;16(4):432-438
BACKGROUND: Moyamoya disease is a chronic cerebrovascular disorders in which stenosis of the major arteries of the circle of Willis at the base of the skull progresses to occlusion. We observed two kinds of collateral pathways from the extracranial to the intracranial arteries. Also we evaluated clinlcal and neuroimaging features of moyamoya disease to give on aid in diagnosis. METHODS: We analysed 17 patients with moyamoya disease through the medical record and neuroimaging (conventional angiography and/or MR angiography) review. Six out of 17 patients were children(< OR =15 years) and the other 11 patients were adults(15 years). There were 8 males and 9 females. RESULTS: In our result, moyamoya disease was more common in the adult. There was bimodal age distribution, so average age of onset in children was 8-year-old and in adult 37-year-old. Common clinical features are seizure (66%), TIA (17%), and psychotic behavior (17%) in childrens and hemorrhages (73%), infarction (18%), seizures (9%) in adults. According to angiographic staging classification of Suzuki et al. (1967), our cases showed distribution of stage I (13%), stage II (8.8%), stage III (65.3%), stage IV (4.3%), stage V (4.3%), stage VI (4.3%). In collateral vessels of moyamoya disease, there were 7 cases of ethmoidal moyamoya, 3 of vault moyamoya and 1 of mixed form. It is interesting that there were five cases of unilateral moyamoya disease and one case had pseudoaneurysm. CONCLUSION: According to our results, we may say that seizures are common in the children and hemorrhages are in the adult. Unilateral moyamoya were mainly occurred in the adult. Ethmoidal collaterals were common among collaterals and stage III had a more cases than others in our neuroimaging data. These clinical and neuroimaging data may help interpretation and diagnosis of moyamoya disease.
