BACKGROUND: Angiogenesis is an essential component of tumor growth and metastasis, and the vascular endothelial growth factor (VEGF) is one of the most important angiogenic factors. Several solid tumors produce substantial amounts of VEGF, which stimulates proliferation and the migration of ednothelial cells, therby inducing neovasculization by a paracrine mechanism. To evaluate the prognostic roles of angiogenesis and VEGF expression in patients with non-small cell lung cancer, the relationship between VEGF expression in tumor tissues, the clinicopathologic features and the overall survival rate were analysed. METHODS: Sixty-nine resected primary non-small cell lung cancer specimens were evaluated. The pareffinembedded tumor tissues were stained by anti-VEGF polyclonal antibodies using an immunohistochemical method to assess VEGF expression. RESULTS: In Forty-one patients (59%), the VEGF antigen was expressed weakly in their tumor tissue, whereas in twenty-eight patients (41%) the VEGF antigen was expressed strongly. The median survival time of the weak VEGF expression group was 24 months, and that of the strong VEGF expression group was 19 months. The three year-survival rates were 35%, 33%, respectively. The survival difference between both groups was not statistically significnat. CONCLUSION: Although results were not statistically significant, the strong expression group tended to poorer prognosis than weak expression group.

Tuberculosis is a common chronic infectious disease, although the spleen is an uncommon organ to harbor tubercle bacilli. Immunocompromised subjects are primarily prone to miliary tuberculosis and in them the spleen is invaded by Mycobacterium tuberculosis. Spleen tuberculosis is manifested commonly as a miliary form. The basic pathology is granulomatous inflammation. The CT finding of splenic tuberculosis are multiple, well-defined, roung or ovoid, low-density masses. Lymphadenopathy in the abdomen and mediastinum and pleural effusion can be found. We report two cases with tuberculosis of the spleen proved by computed tomography and histologic identification. One paitient did not improve following antituberculous medication, so splenectomy was performed. The other patient has been treated with antituberculous medication.

Aspergillosis refers to an infection with any species from the genus Aspergillus. Pleural aspergillosis is an uncommon disease with less than 30 cases having been reported in the literature since 1958. The etiologic factors for this aspergillosis are preexisting pulmonary tuberculosis, bronchopleural fistula, pleural drainage, and a lung resection. Surgical removal of the aspergillus-infected pleura is the main treatment for managing this disease. We have experienced two cases of pleural aspergillosis as a complication of a preexisting chronic empyema. The chest radiographs showed a pyopneumothorax with cavitation and the chest computed tomographic scans revealed a loculated pyopneumothorax with cavity formation suggesting a bronchopleural fistula. A grossly purulent fluid was extracted by thoracentesis, and Aspergillus fumigatus was grown from a fungus culture of the fluid. A decortication, wedge resection with a pleurectomy and a pleuropneumonectomy were performed. The postoperative course was satisfactory and the patients have been in good condition up to now. Pleural aspergillosis is a very rare and potentially life-threatening disease. However, good result without significant complication were obtained by treatment with systemic antifungal agents and surgical removal.

OBJECTIVES: The present study systematically reviewed previous studies published in Korea regarding obesity status of children and adolescents in order to provide valid directions for future research and to help establish evidence-based prevention strategies. METHODS: The articles were selected by searching the primary keyword ‘obesity’ and the secondary keywords ‘children’, ‘young children’, ‘adolescents’ or ‘kids’ on the KISS (Korean Studies Information Service System). Out of 503 articles excluding the overlap, 308 articles were selected with inclusion and exclusion criteria. Secular trends of obesity research, distribution of subjects, potential risk factors for obesity, and intervention method for obesity management were documented. The associations between obesity and dietary factors were summarized. RESULTS: The overall number of research studies has increased since 2000 but obesity management studies have decreased in recent years. Most of the studies used a cross-sectional design. Research on preschool children were extremely limited. Intervention studies targeting males were prevalent. The most significant variables relevant to dietary habits were speed of eating, regular breakfast and snacking. The most significant food and nutrient intake factors were thiamin and iron. Intakes of cereals and animal foods were significantly higher in obese children than the counterparts. CONCLUSIONS: The present review of locally published articles on the obesity status in children and adolescents suggested the need for well-designed further studies focused on risk factors of obesity and on a range of intervention methods conducive to the development of obesity prevention and management programs.

OBJECTIVE: The goal of this study is to determine the efficacy of rapid karyotyping from fetal ascitic fluid. METHODS: In three cases of isolated fetal ascites diagnosed by prenatal ultrasonography, ultrasound guided fetal paracentesis and amniocentesis were performed and successfully obtained. Fetal karyotyping in each case at 29, 30 and 32 weeks gestation using modified lymphocyte culture method was conducted. RESULTS: The chromosomal analysis was successful within 72 hours and abnormalities were detected in two cases and revealed trisomy 21 in each case. Our study demonstrated that the majority distribution of white blood cells was lymphocytes which ranged from 2.1 * 10(6) cells/ml to 3.7 * 10(6) cells/ml and the cell density for culture was at least than 0.35 * 10(6) cells/ml. CONCLUSION: The use of ascitic fluid as a cell source to achieve rapid fetal karyotyping can be valuable when cordocenteis or amniocentesis would be technically more difficult, or when rapid result is required for planning of perinatal management at late second or third trimester gestational age.

PURPOSE: The goal of this study was to compare the effects of treatment of newborn babies with two different surfactants, Curosurf(R) and Surfacten(R). METHODS: We retrospectively reviewed the medical records from 2007 to 2009 and divided the patients into two groups: those who received Curosurf(R) (n=20) and those who received Surfacten(R) (n=21). We compared the groups for sex, gestational age (GA), birth weight, type of delivery, apgar score, maternal history, age at treatment, bronchopulmonary dysplasia (BPD), administration indomethacin for patent ductus arteriosus(PDA), necrotizing enterocolitis (NEC), intraventricular hemorrhage (IVH), periventricular leucomalacia (PVL), retinopathy of prematurity (ROP), pulmonary hemorrhage (PH), pneumothorax (PTX), duration of ventilation, need for oxygen, and administration. RESULTS: The demographic and clinical variables were similar in both groups. The gestational age for Curosurf(R) and Surfacten(R) were 32.7+/-3.1 and, 30.5+/-4.3 weeks, respectively (P=0.08). Six newborns in the Curosurf(R) group and 8 in the Surfacten(R) group developed BPD (P=0.59). No significant differences were noted for NEC, IVH, PVL, ROP, PH, PTX between the two groups (IVH, P=0.14; PVL, P=0.94; ROP P=0.94; PTX P=0.34). The mean duration of ventilation was 16.8 days with Curosurf(R) and 23.7 days with Surfacten(R), but these differences were not statistically significant (P=0.43). The differences in duration of need for oxygen and administration were also not statistically significant (P=0.92, 0.91, respectively). CONCLUSION: This study indicated no significant differences between Curosurf(R) and Surfacten(R). However, because of its convenience and the merit of minimal touching of the babies, the use of Curosurf(R) is recommended.

Hydranencephaly is a term used to describe a group of brain malformations in regard to developing any brain remnants. With most of the cerebral cortex absent, the cerebral hemispheres are replaced by cerebrospinal fluid (CSF), covered with leptomeninges and dura. Hydranencephaly is a rare isolated abnormality occurring in less than 1 per 10,000 births. With the cutting edged sonography, most of the hydranencephalies are screened in antenatal care. Therefore, it is very rare to observe a living preterm with hydranencephaly. From a history of a young, 19-year-old pregnant woman who did not look for the antenatal care, we found out that it was her first pregnancy, she was unmarried and intermittently had alcohol during the pregnancy. After home delivery, a preterm newborn assumed to be 28 weeks of gestational age was placed under surfactant therapy because of respiratory distress syndrome, and then received a mechanical ventilation. Brain sonography showed that most of the cerebral parenchyma, cortical tissue was absent at the 5th day after the birth. Magnetic resonance images (MRI) of brain showed that almost complete absence of cerebrum which was replaced by CSF, hydranencephaly at 81th days from birth. In summary, we report a preterm newborn with hydranencephaly from an adolescent, unmarried woman who had no antenatal care.

PURPOSE: To evaluate the utility of ultrasonograpy(US) as a guide in deciding drainage methods and as a prognostic factor in the prediction of pleural fibrosis, and to compare the effects of drainage methods in patients with tuberculous pleural effusions. MATERIALS AND METHODS: In 51 patients with tuberculous pleural effusion, US patterns of pleural effusion were classified according to degree of septa into three groups, into three groups, as follows: anechoic (n=5), linear septa (n=15), and honeycombing septa (n=31). US-guided drainage methods, including thoracentesis (n=17), percutaneous catheter insertion (n=12), catheter insertion with urokinase instillation (n=22) were employed. Therapeutic effects were evaluated with follow-up chest radiographs after 3 and 6 months. RESULTS: Three months after the procedure, 43 of 51 effusions had drained effectively. US guided drainage failed in eight patients including two of six with linear septated effusion treated with thoracentesis, four of seven with honeycomb septated effusion treated with thoracentesis, and two of six with honeycombing septated effusion treated with catheter drainage. There was no drainage failure in patients with anechoic effusions and in patients with urokinase instillation. Late effects were assessed in 39 patients after 6 months. Follow-up radiographs available in 39 patients demonstrated pleural fibrosis with intercostal space narrowing in 7 patients with honeycomb septated effusion, 3 patients with linear septated effusion, and none of the patients with anechoic effusions. CONCLUSION: The pattern of septa seen on US could be a useful factor for determining drainage methods and predicting late results in tuberculous pleural effusion. Percutaneous catheter drainage with urokinase instillation was a good drainage modality for patients with septated pleural effusions. Pleural fibrosis is more frequently induced by septated pleural effusion than by anechoic pleural effusion.
