1.White Matter Damage in Neonates in the Course of Viral Illness.
Journal of the Korean Society of Neonatology 2007;14(2):263-269
Studies of brain magnetic resonance imaging (MRI) of neonatal white matter damage are few, and descriptions of this type of brain damage are limited. During the past three years, we have encountered three full-term infants with selective white matter damage over the course of their viral illness. All three neonates presented with seizures a few days after showing symptoms of a viral illness. The results of bacterial cultures of the blood, CSF, and stool were negative. Newborn screening tests for organic aciduria, amino acid metabolism disorders, and fatty acid oxidation defects were also negative. In two infants, an electroencephalogram (EEG) showed slow basic activity, which is a typical finding in patients with encephalitis/encephalopathy. The Diffusion-weighted MRI (DWI) showed abnormally high signal intensity localized to the white matter of the corpus callosum, thalamus, internal capsule, or hippocampus. The findings of DWI suggested that the neonates' lesions had occurred recently. All patients recovered completely.

Congenital lobar emphysema has the clinical features of an air block' syndrome with- out the evidence of pulmonary infection or intrabronchial foreign body. The hyperinflated lung causes a compression of uninvolved lobes creating respiratory distress, cyanosis within the first weeks of life. We experienced a case of congenital lobar emphysema diagnosed incidentally by chest reontgenogram in an infant with frequent upper respiratory infection within a few weeks of life. Chest X-ray revealed extensive emphysematous changes in the left upper lobe, shifting of heart and medistinum to the right and compression of the right lung. Respiratory distress, cyanosis and chest wall retraction ensued and left upper lobe Lobectomy was performed successfully.

PURPOSE: The aim of this study was to develop a bioinformatics software and to test it in serum samples of papillary thyroid cancer using mass spectrometry (SELDI-TOF-MS). MATERIALS AND METHODS: Development of 'Protein analysis' software performing decision tree analysis was done by customizing C4.5. Sixty-one serum samples from 27 papillary thyroid cancer, 17 autoimmune thyroiditis, 17 controls were applied to 2 types of protein chips, CM10 (weak cation exchange) and IMAC3 (metal binding - Cu). Mass spectrometry was performed to reveal the protein expression profiles. Decision trees were generated using 'Protein analysis' software, and automatically detected biomarker candidates. Validation analysis was performed for CM10 chip by random sampling. RESULTS: Decision tree software, which can perform training and validation from profiling data, was developed. For CM10 and IMAC3 chips, 23 of 113 and 8 of 41 protein peaks were significantly different among 3 groups (p<0.05), respectively. Decision tree correctly classified 3 groups with an error rate of 3.3% for CM10 and 2.0% for IMAC3, and 4 and 7 biomarker candidates were detected respectively. In 2 group comparisons, all cancer samples were correctly discriminated from non-cancer samples (error rate = 0%) for CM10 by single node and for IMAC3 by multiple nodes. Validation results from 5 test sets revealed SELDI-TOF-MS and decision tree correctly differentiated cancers from non-cancers (54/55, 98%), while predictability was moderate in 3 group classification (36/55, 65%). CONCLUSION: Our in-house software was able to successfully build decision trees and detect biomarker candidates, therefore it could be useful for biomarker discovery and clinical follow up of papillary thyroid cancer.

A 41-year-old female was admitted to our hospital for self-audible wheezing sound and dyspnea. On past history, she has been suffered from chest discomfort, and treated recurrently by other hospitals. But, there was no symptomatic improvement. A stridor and mixed wheezing sound was auscultated on whole lung field. PFT revealed fixed type or variable intra- & extra-thoracic air way obstructive pattern. By bronchoscopy & bronchogram, we found web-like structure on the distal trachea. A bronchoplasty was performed and the post-operative PFT showed slight improvement & she had no more complaints.

PURPOSE: This study was designed to assess the effects of cyclic parenteral nutrition(CP) on parenteral nutrition induced liver diseases. METHODS: Before and after CP, data were collected on diagnosis, age, duration of parenteral nutrition, macronutrients and biochemical parameters. Initially parenteral nutrition was cycled off for 1-2 hours and the off-time was advanced by 0.5-1 hour daily over 1 week. Blood and urine glucose were monitored during procedure. RESULTS: Data on 6 sets of CP in 4 patients, among whom 2 patients had undertaken CP 2 times, respectively, were analyzed. The mean age was approximately 4 months, ranging from 2 to 11 months. Underlying diseases were as follows : 2 cases of microvillous inclusion disease, 1 case of protracted diarrhea of infancy and 1 case of feeding intolerance. The mean duration of parenteral nutrition before CP were 38.6 days, and that of CP was 41.6 days. During CP, the mean total caloric intake of each patient was 107kcal/kg/day, and the mean weight gain was 6.0g/kg/day. After CP, the biochemical parameters changed as follows : bilirubin was decreased in 4 cases, not changed in 1 case but increased in 1 case who had sepsis during CP period; the level of ALT was decreased in 2 cases but increased in 2 cases and not changed in 2 cases. Overall, CP was tolerated well although 3 cases had hypoglycemia(serum glucose concentration less than 40mg/dL) at the initial CP period. CONCLUSION: CP has potential beneficial metabolic effects on total parenteral nutrition induced cholestasis with minimal complications.

BACKGROUND: Diagnosis of subpulmonary effusion is thought to be somewhat difficut more than pulmonary effusion. Clinical course and pathophysiology are thought to be different from typical pulmonary effusion. This study was done for increasing high suspicious index and early diagnosis of subpulmonary effusion. METHOD: Among the patients at dept. of chest medicine, National Medical Center from January 1990 to Dec. 1993, 232 cases of typical pulmonary effusion and 42 cases of subpulmonary effusion were studied. RESULT: 1) The ratio of subpulmonary effusion and typical pulmonary effusion was about 1:5 2) Male to Female ratio was 1:1 in both effusion. 3) Rt. side pleural and subpleural effusion were slightly predominant. 4) Subjective symptoms are chest pain, cough and exertional dyspnea. There is no difference between subpulmonary and typical pulmonary effusion. 5) Duration of symptom was slightly longer in subpulmonary effusion. 6) The most common cases of pleural effusion is tuberculosis in both subpulmonary & typical pulmonary effusion. Non-specific pleuritis was more common in subpulmonary effusion. 7) Pleural effusion was recurred about one fifth in both subpulmonary & pulmonary effusion. CONCLUSION: We studied clinical course and laboratory findings between subpulmonary & pulmonary effusion. However there are no definite difference between subpulmonary & pulmonary effusion. Duration of symptom was slightly longer in subpulmonary effusion. Most common cause was tuberculosis. Non specific pleuritis was more prevalent in subpulmonary effusion.

PURPOSE: The aim of this study was to assess health-related behavior of pregnant women and breastfeeding mothers by investigating relevant risk factors. METHODS: Data of 10,396 women (age 19 to 49 years) from the Korea National Health and Nutrition Examination Survey report from 2007 to 2012 was used to analyze factors associated with health-related behavior. The subjects were divided into pregnant women; breastfeeding mothers; and non-pregnant women. Bottle feeding mothers were excluded. RESULTS: Current smoking rate including self-reported smoker and/or positive cotinine urine test were lower for pregnant or breast-feeding group than non-pregnant group. Heavy-drinking was not different among groups while monthly drinking rate was higher in non-pregnant group. Rate of stress recognition was lower in pregnant and breast-feeding group than non-pregnant group. Rate of experience for depressive symptoms and rate of suicidal ideation were not different among groups. CONCLUSION: Pregnant women and breast-feeding mothers maintain a good pattern of health-related behavior compared to non-pregnant women. However, substantial proportion of pregnant women and breast-feeding mothers continue to drink and smoke. This shows the need for a plan that will modify health-related behavior.
