Background : Delayed treatment of pulmonary tuberculosis is an important problem because it results in greater mortality and the nosocomial transmission of tuberculosis. This study was conducted to analyze the factors that contribute to the delayed treatment of pulmonary tuberculosis in a university hospital and we wanted to provide basic data for instituting an effective management program for tuberculosis. Methods : we retrospectively reviewed the medical records of 155 patients with smear-positive or culture-positive pulmonary tuberculosis and who were treated between May 1999 and October 1999. A case-control study was performed to analyze the factors. We then tried to follow up the patients in delayed treatment group via telephone for the purpose of assessing the therapeutic interventions. Results : Among 150 patients, 55 (37%) were included in the delayed treatment group. The factors associated with delayed treatment on the univariate analysis included age (61 vs 40 years old; p <0.001), a smear-negative sputum test for acid-fast bacilli (AFB) (85% vs 55%; p <0.001) and no visits to a private clinic before the patient presented to the university hospital (56% vs 36%; p = 0.014). Multivariate analysis revealed that old age (p = 0.001), a smear-negative sputum for AFB (p = 0.001), and lower lobe infiltrate on chest X-ray (p = 0.041) were the independent predictors of delayed treatment. Of the 22 patients who did not receive any treatment, 20 of them 91%) consented to our suggestion of revisiting the hospital. Conclusion : Delayed treatment of patients with pulmonary tuberculosis is not uncommon in a university hospital. Old age, smear-negative for AFB, and lower lobe infiltrate on chest X-ray are the risk factors for delayed treatment. A more systematic management system is required for achieving better control of tuberculosis.

Purpose: The purpose of this study is to evaluate the long-term stability of the improved symptoms and accommodative functions after completion of accommodative therapy. Methods: Seven children (mean age${\pm}$SD: $12{\pm}1.41$ years) who were successfully treated with a vision therapy program for either accommodative insufficiency or infacility were followed for 1 year. The visual symptoms of the subjects were measured by the College of Optometrists in Vision Development Quality of Life (COVD-QOL) checklist, and this was followed by measurement of the monocular and binocular accommodative facility with ${\pm}2.00$ D flipper lens. Results: The mean visual symptoms at the 1 year follow-up examination ($15.14{\pm}8.59$) showed a small increase, but there was no significant difference (p=0.446) from post-therapy ($11.86{\pm}7.22$). There was small regression in the monocular (left eye, $13.86{\pm}3.93cpm$) and binocular ($11.14{\pm}3.13cpm$) accommodative facility at the 1 year follow-up examination, but there were no significant different from the monocular ($15.86{\pm}4.14cpm$, p=0.147) and binocular ($13.21{\pm}3.76cpm$, p=0.066) accommodative facility measurements at post-therapy. Also, every subject met the normative values of ${\geq}7$ cpm for monocular accommodative facility and ${\geq}5$ cpm for binocular accommodative facility in the long-term. Conclusions: There was long-term maintenance of the improved visual symptoms and accommodative functions, and so it is clear that the positive therapeutic effects persist with accommodative therapy.

Purpose : To evaluate the potential prognostic value of the antithrombin-III (AT-III) level in the children with acute lung injury (ALI), we analyzed several early predictive factors of death including AT-III level at the onset of ALI and compared the relative risk of them for mortality. Methods : Over a 18-month period, a total of 198 children were admitted to our pediatric intensive care unit and 21 mechanically ventilated patients met ALI criteria, as defined by American-European consensus conference, i.e., bilateral pulmonary infiltrates and $PaO_2/FiO_2$ lower than 300 without left atrial hypertension. Demographic variables, hemodynamic and respiratory parameters, underlying diseases, as well as Pediatric Risk of Mortality-III (PRISM-III) scores and Lung Injury Score (LIS) at admission were collected. AT-III levels were measured within 3 hours after admission. These variables were compared between survivors and non-survivors and entered into a multiple logistic regression analysis to evaluate their independent prognostic roles. Results : The overall mortality rate was 38.1% (8/21). Non-survivors showed lower age, lower lung compliance, higher PEEP, higher oxygenation index (OI), lower arterial pH, lower $PaO_2/FiO_2$, higher PRISM-III score and LIS, and lower AT-III level. PRISM-III score, LIS, OI and decreased AT-III level (less than 70%) were independently associated with a risk of death and the odds ratio of decreased AT-III level for mortality is 2.75 (95% confidence interval; 1.28-4.12) Conclusion : These results suggest that the decreased level of AT-III is an important prognostic factor in children with ALI and the replacement of AT-III may be considered as an early therapeutic trial.
Purpose : The aim of this study was to compare the clinical effects of modified porcine (Curosurf$^{(R)}$) and bovine (Newfactan$^{(R)}$) surfactants in the treatment of neonatal respiratory distress syndrome. Methods : Between April 2004 and December 2006, 65 neonates (birth weight ${\leq}$2,500 g and gestational age ${\leq}$35 weeks) with neonatal respiratory distress syndrome were treated in our neonatal intensive care unit with surfactant. Thirty-one neonates received Curosurf$^{(R)}$ and 34 neonates received Newfactan$^{(R)}$. The neonates were not enrolled if they had major congenital anomalies or meconium aspiration syndrome. We compared the changes in respiratory parameters after surfactant instillation, the incidences of acute and chronic complications, and the mortality between the two treatment groups. Results : Neonatal and maternal demographic characteristics were not different between the groups. The patterns of change in the respiratory parameters after surfactant instillation were not statistically different between the groups. The incidences of surfactant reinstillation and acute complications, such as pneumothorax, patent ductus arteriosus, pulmonary hemorrhage, and grade 3-4 intraventricular hemorrhage, were not different between the neonates who received Curosurf$^{(R)}$ and the neonates who received Newfactan$^{(R)}$. There were no statistically significant differences in the duration of mechanical ventilation, oxygen therapy, hospitalization, prevalence of bronchopulmonary dysplasia, periventricular leukomalacia, retinopathy of prematurity, necrotizing enterocolitis, and mortality between the groups. Conclusion : In the present comparative study, no significant differences in the clinical effects of Curosurf$^{(R)}$ and Newfactan$^{(R)}$ were observed.
Purpose : Transient wall motion abnormality and contractile dysfunction of the left ventricle (LV) can be observed in patients with coronary artery disease due to post-stress myocardial stunning. To understand clinical characteristics of stress induced LV dysfunction, we have compared the findings of exercise stress test, myocardial perfusion SPECT and coronary angiography between subjects with and without post-stress LV dysfunction. Materials and Methods : Among subjects who underwent exercise stress test, myocardial perfusion SPECT and coronary angiography within a month of interval, we enrolled 36 patients with post-stress LV election fraction (LVEF) was $\geq5%$ lower than rest (stunning group) and 16 patients with difference of post-stress and rest LVEF was lesser than 1 %(non-stunning group) for this study. Treadmill exercise stress gated myocardial perfusion SPECT was performed with dual head SPECT camera using 740 MBq Tc-99m MIBI and coronary angiography was also performed by conventional Judkins method. Results : Stunning group had a significantly higher incidence of hypercholesterolemia than non-stunning group(45.5 vs. 7.1%, p=0.01). Stunning group also had higher incidence of diabetes mellitus and lower incidence of hypertension, but these were not statistically significant. Stunning group had larger and more severe perfusion defect in stress perfusion myocardial SPECT than non-stunning group(extent 18.2 vs. 9.2%, p=0.029; severity 13.5 vs. 6.9, p=0.040). Stunning group also had higher degree of reversibility of perfusion defect, higher incidence of positive exercise stress test and higher incidence of having severe stenosis ($80{\sim}99%$) in coronary angiography than non-stunning group, but these were not statistically significant. In stunning group, all of 4 patients without perfusion defect had significant coronary artery stenosis and had received revascularization treatment. Conclusion : Patients with post-stress LV dysfunction had larger and more severe perfusion defect and severe coronary artery stenosis than patients without post-stress LV dysfunction. All of the patients without perfusion defect in stunning group had significant coronary artery stenosis and needed revascularization. Therefore, we suggest that invasive diagnostic procedures and therapeutic interventions might be needed in patients with post-stress LV dysfunction.
It was reported that the novel compounds (LP9M80-H) of $Liriope$$platyphylla$ regulate glucose transporter (Glut) biosynthesis by activating the insulin-signaling pathway in the liver and brain of ICR mice. To investigate the therapeutic effects of LP9M80-H on the pathology of diabetes and obesity, alterations of key factors related to symptoms were analyzed in the Otsuka Long Evans Tokushima Fatty (OLETF) rats treated with LP9M80-H for 2 weeks. The abdominal fat masses in the LP9M80-H-treated group were lower than the vehicle-treated group, although there was no difference in body weight between the two groups. Additionally, when compared to the vehicle-treated group, LP9M80-H treatment induced a significant decrease in glucose levels and an increase in the insulin concentration in the blood of OLETF rats. A high level of insulin protein was also detected in pancreatic ${\beta}$ cells of LP9M80-H-treated OLETF rats. A significant reduction in the concentration of lipids and adiponectin was detected only in LP9M80-H-treated OLETF rats. Furthermore, the expression of insulin receptor ${\beta}$ and the insulin receptor substrate (IRS) was dramatically decreased in LP9M80-H-treated OLETF rats compared to the vehicle-treated group. Of the glucose transporters located downstream of the insulin-signaling pathway, glucose transporters (Glut) -2 and -3 were significantly decreased in LP9M80-H-treated OLETF rats, while the level of Glut-4 was maintained under all conditions. Therefore, these results suggest that LP9M80-H may contribute to relieving symptoms of diabetes and obesity through glucose homeostasis and regulation of lipid concentration.

Background: Lung cancer-associated hypercalcemia is one of the most disabling and life-threatening paraneoplastic disorders. Humoral hypercalcemia is responsible for most lung cancer-associated hypercalcemia. Patients with hypercalcemia are usually in the advanced stage with obvious bulky tumor and carry a poor prognosis. Materials and Methods: Total 29 patients satisfied the following criteria: histologically proven primary lung cancer, corrected calcium level ${\geq}$ 10.5 mg/dL, and symptoms which could possibly be attributed to hypercalcemia. In this retrospective study, we evaluated the various clinical aspects of hypercalcemia, in relation to cancer stage, histologic cell type, mass size, bone metastasis, performance status, and other possible characteristics. Results: Total 29 lung cancer patients with hypercalcemia were studied, and most of them had squamous cell carcinoma in their histologic finding. The incidence of hypercalcemia was significantly higher between 50 and 69 years of age, and in the advancement of cancer stage. Although serum calcium level showed positive correlation with mass size, performance status, and bone metastasis, it was not significant statistically. Altered consciousness was significantly more frequent in the patients with higher serum calcium level. There were no differences in effectiveness among therapeutic regimens. Hypercalcemia was more frequently in the later stage of disease than during the initial diagnosis of lung cancer. Most of the patients died within 1 month after development of hypercalcemia. Conclusion: We concluded that hypercalcemia in lung cancer is related to extremely poor prognosis, and may be one of the causes of death and should be treated aggressively to prevent sudden deterioration or death.

Purposes : Renal involvement is a potentially serious complication of systemic lupus erythematosus (SLE). There have been only few studies of lupus nephritis in pediatric age. In this study, the clinical manifestations, pathologic findings, response to treatment, and clinical course of lupus nephritis in children were analyzed. And the results will provide basic data for future nation-wide prospective multi-center study. Methods . The medical records of 46 children clinically and pathologically diagnosed to have lupus nephritis at Seoul National University Children's Hospital during 1986 to 1997 were analyzed retrospectively. Results : 1) The median age of diagnosis of lupus nephritis was 12.8 years ($2\;years\~\;15year$ 8months), and the sex ratio was 1:2.5. 2) FANA($85.7\%$), anti-ds-DNA antibody ($78.0\%$), and malar rash ($60.8\%$) were the most common findings among the classification criteria by ARA Decreased C3 was detected in $88.9\%$ of patients. 3) Hematuria ($87.0\%$) was the most common renal symptom, and WHO class IV lupus nephritis was identified in 41 cases by renal biopsy. 4) In most of patients, the disease activity was controlled relatively well with a single or combined therapy of prednisolone, azathioprine, or cyclophosphamide. The response revealed no difference according to the mode of treatment. 5) Infection, especially of Varicella-Zoster virus and candida, was the most common complication during the disease course. Conclusion : The renal involvement was noted in $87.0\%$ of childhood SLE, and $89.1\%$ of renal lesions was WHO class IV lupus nephritis known to associated with poor long-term prognosis. So, aggressive treatment using immunosuppressants in the early disease course may be helpful to increase long-term prognosis of lupus nephritis. A prospective multi-center study is necessary to analyze the therapeutic efficacy of various treatment modalities.
Purpose : Edema is one of the cardinal features of nephrotic syndrome. Although the pathogenesis of edema is not entirely understood, it is caused by hypovolemia or hypervolemia by different mechanisms. Accordingly it is important to evaluate the volume status of patients in order to treat the edema, but it is difficult to evaluate the patient's volume status only by clinical parameters. The quotient of urine sodium and potassium excretion $U_K/(U_{Na}+U_K)$ is introduced as a more useful way to evaluate volume status. In this study we will propose the usefulness of $U_K/(U_{Na}+U_K)$ in evaluating the volume status of children with nephrotic syndrome. Methods : Primary nephrotic syndrome patients at Yeungnam University Hospital since January 1995 to June 2005, were included in the study. We analyzed clinical parameters such as tachycardia, cardiomegaly, pleural effusion, blood chemistry and urinalysis prospectively. We defined hypovolemia when $U_K/(U_{Na}+U_K)$ exceeded 60%. Intravenous albumin and diuretics were administered to hypovolemic edematous patients. On the other hand, hypervolemic edematous patients were treated only with diuretics. Results : There were 50 cases of primary nephrotic syndrome patients(hypervolemia: 29 vs hypovolemia: 21). There were no significant differences in clinical symptoms and laboratory findings except for FeNa While $F_eNa$ and $U_K/(U_{Na}+U_K)$ had a significant negative correlation, BUN and $U_K/(U_{Na}+U_K)$ had a significant positive correlation. Urine output after edema treatment was effective and there were no treatment-related side effects in both groups. Conclusion : FeNa, BUN and $U_K/(U_{Na}+U_K)$ are a useful parameters for evaluating volume status of edematous nephrotic syndrome patients. We could suggest a therapeutic option for using albumin and/or diuretics according to volemic status by means of measured $U_K/(U_{Na}+UK)$.
Purpose: Dietary protein induced proctocolitis (DPIPC) can be considered as a cause of rectal bleeding or blood streaked stool in otherwise healthy-looking infants in the first several months of life. Failure to appreciate this entity may lead to inappropriate diagnostic or therapeutic intervention. This study aimed to ascertain the clinical features, treatment and prognosis of DPIPC. Methods: We reviewed 13 infants retrospectively, presented with bloody stool in early infancy. They were diagnosed as DPIPC clinically in Pusan National University Hospital from May 2002 to June 2004. Results: Seven males and six females were included. The mean age at onset of bleeding was $96.8{\pm}58.8days$. The mean frequency of hematochezia was $2.6{\pm}2.5$ times a day. Duration from onset of symptom to diagnosis was $35.5{\pm}55.0days$ and duration from onset of symptom to resolution of bleeding was $58.7{\pm}67.0days$. Nine (69.2%) were exclusively breast-fed infants and two (15.4%) were formula-fed infants. All but one infant did not have family history of other allergic diseases. A dietary history of ingestion of cow's milk, nut or shellfish was present in three mothers. Peripheral eosinophil count was normal to slightly elevated (total WBC count $10,555{\pm}3,145/mm^3$, relative eosinophil count $6.3{\pm}3.0%$, absolute eosinophil count $659.0{\pm}532.2/mm^3$). Sigmoidoscopy revealed lymphonodular hyperplasia with surrounding hemorrhagic spots in the rectosigmoid colon in 6 infants. Histopathologic finding of colonic biopsies in 5 infants showed chronic inflammation with lymphoid follicular hyperplasia (5 infants), crypt abscess (3 infants), or mild infiltration of eosinophils (less than 20/high power field) in the lamina propria. Spontaneous resolution of rectal bleeding occurred in all infants without dietary change or medicine. Conclusion: Most infants with DPIPC experience a very benign course and have spontaneous resolution of rectal bleeding without changes in the mother's diet. In the case of strong evidence for DPIPC we suggest deferring further invasive investigation and continuing breast feeding.
