Isoimmune hemolytic disease of the newborn due to anti-E is a disease characterized by the progressive neonatal hyperbilimbinemia and anemia which is caused by the IgG antibody transmitted from the mother to the ferns. Authors have experienced two cases of isoimmune hemolytic disease due to anti-E, who presented with jaundice on the first and the second day of life, respectively. The ABO and Rh blood types of their mother and father were B, CcDee and O, ccDEE, respectively. Both babies showed positive direct Coombs test and the mother showed strong positive indirect Coombs test. Antibody identification tests were made only in the first case and the mother, both of which revealed anti-E antibody. The first case was treated with phototherapy for 3 days and two blood transfusions. The second case was treated with phototherapy for 6 days and two exchange transfusions.

BACKGROUND: Leptin has been found to be involved in the regulation of hematopoiesis processes and angiogenesis. Therefore, we investigated the effect of leptin in the proliferation and angiogenesis of peripheral blood (PB)-derived endothelial progenitor cells (EPCs). METHODS: Mononuclear cells were isolated from PB of healthy male volunteers and were cultured in endothelial cell growth medium-2 (EGM-2). After 6 days of culture, cells were treated with 50 ng/mL vascular endothelial growth factor (VEGF) and/or with various concentrations of leptin (10 ng/mL, 100 ng/mL, 1microgram/mL, and 10 microgram/mL) and were further cultured for one week. Proliferation of EPCs was examined by an assay measuring the uptake of 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbo cyanine-labeled acetylated LDL (Dil-ac-LDL) and tubule formation on a matrigel. The control group of cells was not treated with VEGF and/or leptin. RESULTS: The number of Dil-ac-LDL labeled-EPCs, tubule formation on matrigel and the number of cells present along tubules were significantly increased in the leptin-treated groups of cells as compared to the control group or VEGF treated group of cells (P<.05). The effect was synergistically increased in the group of cells co-treated with leptin and VEGF. The number of EPCs was increased in a leptin dose-dependent manner that was maximal at a concentration of 1microgram/mL leptin. CONCLUSION: This study shows that leptin increased in vitro proliferation and angiogenesis of EPCs derived from peripheral blood.

PURPOSE: This study was conducted to assess the effects of lights-out at nighttime on body weight, physiological variables, and behavioral status in premature infants and to provide basic data for applying lights-out at night time in premature infants. METHODS: Premature infants of over 32 weeks' corrected age were included in this study (January 2015-June 2015), and were allocated to two groups according to the lights-out at night for 5 hours: study group and control group. Lights-out was applied to the study group from midnight for five hours in a quiet environment. RESULTS: Fifty-two infants were included in the study: 26 in the study group and 26 in the control group. Growth rates of body weight, height, and head circumference were higher in the study group compared to the control group, but there were no statistical differences. In the physiological variables, heart rate decreased by 6.9 beats per minute in the study group, but it increased by 2.7 beats per minute in the control group (P<0.0001) during applied 5 hours at night. Anderson Behavioral State Score decreased in the study group compared to the control group (P=0.042). CONCLUSION: Lights-out at night decreased the heart rate and made the behavioral status more stable. To understand the effects of lights-out on long-term growth and development of premature infants at the highest risk of delayed growth and development, further studies with a larger number of premature infants are needed.

Object of this study was to to evaluate the laterality of local cerebral cellular metabolism in various locations of the brain related to the symptomatic side of patients with clinically diagnosed idiopathic Parkinson's disease (IPD) and to verify GABA-related pathophysiology in IPD by comparing postoperative changes in (GABA+Glutamate)/Cr ratio from patients with IPD after stereotactic pallidotomy and thalamotomy. Fourteen patients with IPD(10 males and 4 females: age range 39-67 years) participated in the study. The patients were classified into two disease subgroups, one for tremor dominant group(n=7, T group), and the other bradykinesia and rigidity dominant one(n=7, B&R group). For T group, stereotactic VL(Vop, Vim) thalamotomy and subthalamotomy was performed and for the B&R group, stereotactic posteroventrolateral pallidotomy was selected. In Vivo 1H MRS study was performed on a 1.5 T MRI/MRS system(GE Sigma Advantage, version 4.8) using STEAM sequence after water suppression with CHESS RF pulse and dephasing gradients. After peak areas of creatine/phosphocreatine(Cr), choline-containning compound(Cho), N-Acetyl Aspartate(NAA), r-aminobutyric acid, (GABA) and glutamate(Glu) were calculated and processed, the metabolic ratios of NAA/Cr, Cho/Cr, and (GABA+Glu)/Cr in three different locations were calculated and compared with clinical symptoms and its changes after surgery. For the neuronal laterality in patients with IPD, there was significant differences of NAA/Cr ratio between the right and left sides of substantia nigra, thalamus and pallidum(p=0.00170). The magnitude of difference in NAA/Cr ratios between right and left side were significantly larger in substantia nigra(p=0.0141). Compared to the normal control values(1.82+/-0.52 in ages 27-50, 1.71+/-0.54 in ages 51-70 years), the neuronal loss was generally observed in at least one of three locationsin all patients. Moreover, NAA/Cr ratio was substantially lower in ipsilateral than contralateral substantia nigra of the parkinsonian symptomatic side. For preoperative(GABA+Glu)/Cr ratios of thalamus contralateral to the symptomatic side compared to that of ipsilateral, it was significant larger in thalamus of B&R group and significant smaller in T group. In the pallidotomy group, there was significant increase in the operated pallidum, whereas significant decrease in (GABA+Glu)/Cr ratios were noted in the operated side thalamus. And in the thalamotomy group, there were significant increase in the operated thalamus, whereas in the operated side pallidum, significant decrease in (GABA+Glu)/Cr ratios were noted. Neuronal laterality, pallidal neuronal loss and postoperative changes in GABA activity in patients with IPD were demonstrated on the basis of NAA/Cr and (GABA+Glu)/Cr ratio by In Vivo 1H MRS. The neuronal laterality was detected in the substantia nigra of all the parkinsonian patient, and NAA/Cr ratios in unilateral and bilateral disease were consistently lower in ipsilateral than in contralateral substantia nigra of the Parkinsonian disease side. Our result suggests that there may be another ongoing pathological process of ipsilateral neuronal degeneration with contralateral dopaminergic neuronal loss. The result of neuronal loss in pallidum supports with the previous reports concerning striatal degeneration in IPD. Our results concerning postoperative changes of (GABA+Glu)/Cr ratio suggests that separate pathophysiologic mechanisms may be involved in the development of two dominant symptom groups of IPD. That is, for the B&R group, pallidal overinhibition to the thalamus by the GABA-ergic system as previously noted, but for T group, a process other than GABA inhibitory mechanism with or without it may be involved.

With the increasing use of PD as a replacement therapy in chronic renal failure, the number of complications related to PD also has increased. One of these is hydrothorax associated with pleuroperitoneal communications. Diagnosis is based upon confirming that the fluid in pleural space is dialysate. The chemical characteristics of the pleural fluid can help diagnose dialysate in pleural space. One can use dialysate mixed with dye (methylene blue, indigo). Peritoneographies with contrast and radionucleotides are safe, accurate, and reliable methods of diagnosing peritoneal defects. While these substances do not damage the peritoneum, their diffusion is low. We report 2 cases of hydrothorax associated with pleuroperitoneal communications in CAPD patients. We employed CT peritoneography and peritoneoscintigraphy to diagnose the hydrothorax associated with pleuroperitoneal leak.

We describe below a case of Zellweger syndrome case with facial dysmorphism, profound hypotonia, and hepatomegaly. He died at the age of 2 months. Zellweger syndrome is a disease marked by the absence of hepatic and renal peroxisomes. Because peroxisomes have many vital anabolic and catabolic functions within the cell, their absence results in profound cellular dysfunction. A biochemical study of plasma revealed elevation of very long chains of fatty acids and pipecolic acid, consistent with peroxisomal disorder. The cultured skin fibroblasts showed a marked decrease in plasmalogen synthesis enzyme : dihydroxyacetonephosphate acyl transferase(DHAP-AT) The clinical characteristics and biochemical findings led to the diagnosis of Zellweger syndrome. The pattern of inheritance is autosomal recessive, hence genetic counseling can help the families. In infantile hypotonia patients with unknown cause, peroxisomal disorder should be included in the differential diagnosis. We report the first confirmed case of Zellweger syndrome by enzyme assay in Korea.

BACKGROUND: The aim of the present study was to determine the population-based prevalence of diabetes mellitus (DM) and prediabetes in a rural district of Daegu City, Korea. METHODS: Between August and November 2003, a community-based health survey of adults aged 20 years and older was performed in the rural district of Dalseong-gun in Daegu City. A total of 1,806 of all eligible individuals agreed to participate. Fasting plasma glucose was measured in all participants. Two hour oral glucose tolerance was measured in the 1,773 participants for whom there was neither an established diagnosis of DM nor evidence of DM according to fasting glucose levels. The prevalence of DM and prediabetes was determined according to the 2003 criteria of the American Diabetes Association. Subjects with prediabetes were classified into one of three categories of glucose intolerance: isolated impaired fasting glucose (IFG); isolated impaired glucose tolerance (IGT); or combined IFG and IGT. RESULTS: The prevalence of DM was 12.2%. The highest prevalence rates were observed in subjects in their seventies. A total of 34.7% of all subjects who were assigned a diagnosis of DM in the present study had not been diagnosed previously. The prevalence of prediabetes was 22.7%. The highest prevalence rates were observed in subjects in their fifties. CONCLUSION: The present study identified prevalence rates of 12.2% for DM (age-standardized prevalence rate [ASR], 6.8%), and 22.7% for prediabetes (ASR 18.5%). These results emphasize the need for community health promotion strategies to prevent or delay the onset of DM in individuals with prediabetes.

BACKGROUND: Thyroid nodules are commonly encountered in clinical practice and a p revalence of general population is 19~67% by ultrasonography. We made a study to investigate clinical characteristics, malignancy ratio of thyroid incidentalomas and predicting factors for diagnosis of malignancy, to provide recommendation for evaluation. METHODS: We retrospectively evaluated the medical records of 320 patients who visited Kyungpook National University Hospital from July 2001 to December 2003 with non palpable thyroid nodules. We reviewed physical examination, ultrasonographic findings, laboratory findings, histology of thyroid nodules and did statististic analysis to examine relationship to malignancy. RESULTS: 52 patients revealed papillary carcinomas and malignancy rate whin incidentalomas is 9.3%. Sonographic findings of solid structure, hypoechogenecity, punctate calcification, ill defined margin, irregular shape showed meaningful diagnostic value for malignancy. CONCLUSIONS: Combination of meaningful sonographic findings increased possibility of maliganancy and require active mangements including recurrent fine needle aspiration and surgery if needed.
