We analyzed ERCP findings of 15 patients with clonorchiasis, that were confirmed by stool examination and operation from May, 1976 to September, 1980. The results were as follows. 1) Filling defects due to adult worm of clonorchis sinensis were significant direct findings of clonorchiasis. 2) Irregular stenosis, fuzziness, raggedness, peripheral dilation and disturbance of peripheral filling of intrahepatic bile ducts were significant indirect findings of clonorchiasis. 3) ERCP was excellent method to evaluate biliary tree in patients with clonorchiasis, who showed obstructive jaundice.

4.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.

Major surgeries such as total hip arthroplasty are likely to be associated with high incidences of perioperative morbidity and mortality, which may be compounded by the increased risk of heavy bleeding. It has been reported that these complications may occur more commonly when general, rather than spinal anesthesia is used. This study was undertaken to investigate whether spinal anesthesia is clinically safer than general anesthesia undergoing total hip arthroplasty. Forty-one patients were classified randomly into 2 groups to compare the effects of spinal versus general anesthesia on blood pressure, pulse rate, amounts of blood loss and transfusion, and complications in total hip arthroplasty. In general anesthesia groups, systolic blood pressure significantly increased from the baseline of 125.6+/-14.4 mmHg to 137.2+/-12.7 mmHg at 10 minutes post-induction (p<0.05). Pulse rate also increased from the baseline of 75.2+/-1.6 beats/min to 90.3+/-8.0 beats/min at 10 minutes post- induction. In spinal anesthesia group, systolic blood pressure significantly decreased from the baseline of 121.5+/-11.5 mmHg to 113.4+/-15.8 mmHg at 10 minutes post-induction (p<0.05). Pulse rate also decreased from the baseline 78.6+/-11.9 beats/min to 74.2+/-5.2 beats/min at 10 minutes post-induction. After 10 minutes post-induction, systolic blood pressure and pulse rate became stable in both groups. The amount of intraoperative blood loss was less in spinal anesthesia group (510+/-140 ml) than in the g anesthesia group (720+/-150 ml). However, difference in the amount of blood transfused was not significant in the two groups. Postoperative hemoglobin values showed a marked decreases in both group. The complication rates were similar in both groups. It appears that blood loss during total bip arthroplasty is less in the spinal than general anesthesia group. However, other clinical variables investigated are not significantly different in the two groups.

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.

Journal of the Korean Ophthalmological Society 2014;55(7):1071-1076
PURPOSE: To compare the refractive measurements obtained using a photorefractor (PlusoptiX S09, PlusoptiX GmbH, Germany) with those obtained using cycloplegic refraction in children. METHODS: We assessed the refractive status of 268 eyes in 134 children. The values acquired via photorefraction with a PlusoptiX S09 device were compared with those obtained by cycloplegic retinoscopy. Hyperopia (> or =+3.5 D), myopia (> or =-3.0 D), with the rule or against the rule astigmatism (> or =-1.5 D), and oblique astigmatism (> or =-1.0 D) were set as diagnostic criteria for refractive amblyopia risk factors (RARFs). The difference in the detection of RARFs by the two methods was the main outcome measure. RESULTS: The average spherical refractive power was -0.81 +/- 1.68 D for PlusoptiX S09 versus -0.26 +/- 2.00 D for cycloplegic retinoscopy (average difference -0.54 +/- 0.61 D; p < 0.001). The average spherical equivalent was -1.20 +/- 1.62 D for PlusoptiX S09 versus -0.64 +/- 1.94 D for cycloplegic retinoscopy (average difference -0.56 +/- 0.62 D; p < 0.001). The average cylinder power was -0.79 +/- 0.93 D for PlusoptiX S09 versus -0.76 +/- 0.94 D for cycloplegic retinoscopy (average difference -0.03 +/- 0.33 D; p = 0.135). Even though cycloplegic retinoscopy is considered the gold standard, the sensitivity and specificity for detecting RARFs with the PlusoptiX S09 were 88.0% and 96.3%, respectively. CONCLUSIONS: PlusoptiX S09 is a relatively useful method for detecting RARFs, but the device tends toward myopic shift compared to cycloplegic refraction, and hyperopia is underestimated.

Melanotic Schwannoma arising from the acoustic nerve is extremely rare and only three cases have been reported. We report an additional case of melanotic schwannoma occuring at the left cerebellopontine angle in a 53-year-old man presented with left facial numbness and tinnitus. After surgical removal of the mass, there has been no evidence of recurrence for 13 months.
