Objective: The objective of the study was to determine the effectiveness of myoinositol (MI) supplementation in the prevention of gestational diabetes mellitus (GDM) among high-risk patients. Materials and Methods: Comprehensive and systemic online searches were performed on PubMed, MEDLINE, Ovid, and Cochrane. Cross-referencing from related articles was also done. Only studies published in English were included in the study. We selected all randomized controlled trials on MI and singleton pregnant women with high risk for GDM. Data Collection and Analysis: Five randomized controlled trials were evaluated by two independent reviewers. For each comparison, the quality of evidence was assessed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Cochrane Collaboration tool. Review Manager 5.3 was used to generate the risk of bias evaluation and the analysis of the results. Main Results: The present study identified five randomized controlled trials involving 871 participants. The comparison of the studies showed a statistically significant reduction in the incidence of GDM in MI supplementation versus the control group (odds ratio [OR] = 0.32, 95% confidence interval [CI] = 0.19–0.53, P = 0.0001, Z = 4.36) by 68%. Similarly, there is a greater reduction in the incidence of fetal macrosomia among patients in the MI group than the controlled group (OR = 0.24, 95% CI = 0.07–0.78; P = 0.02, Z = 2.36) by 78%. However, there was no difference in terms of incidence of gestational hypertension (OR = 0.61, 95% CI = 0.19–2.01; P = 0.42, Z = −0.81), cesarean section (OR = 0.89, 95% CI = 0.65–1.22; P = 0.47, Z = 0.72), and neonatal hypoglycemia (OR = 0.35, 95% CI = 0.01–8.80; P = 0.53, Z = 0.63) outcomes. Conclusion MI supplementation taken at 4 g daily would decrease the incidence of GDM and fetal macrosomia. There was no statistically significant reduction in the risk of gestational hypertension, cesarean section, and neonatal hypoglycemia in the supplementation of MI.

OBJECTIVE: To compare the perinatal outcomes of pregnant women with 100 g oral glucose tolerance test (OGTT) proven impaired glucose tolerance (IGT), with normal control and gestational diabetes mellitus (GDM) groups. METHODS: 159 pregnant women who had visited our medical center between March 2002 and March 2004, positive (> or = 140 g) for 50 g OGTT were included in this study. IGT was defined by the presence of one abnormal 100 g OGTT glucose value, and they were compared with the control group, and the GDM group(with at least 2 abnormal glucose values). The maternal and neonatal outcomes were assessed among three groups. RESULTS: Even though familial history of DM was significantly higher in the IGT and GDM group (p<0.001) compared with the control group, no difference was observed in the frequency of previous GDM. The rate of fetal macrosomi a (>4 kg) and hypoglycemia was significantly increased in GDM group than other groups. The difference in the frequency of i) large for gestational age birthweight (>90 percentile) ii) preterm delivery, iii) APGAR score (1-min and 5-min), iv) shoulder dystocia, and v) congenital anomalies among the three groups was not notable-however, the incidence of neonatal hyperbilirubinemia was significantly higher and duration of NICU admission is significantly longer in the IGT group, compared to the control group (p<0.001). In maternal outcomes, whereas no significant difference was observed concerning the frequency of i) polyhydramnios (>95%) ii) infections (genitourinary and surgical wounds) in the three groups, the prevalence of preeclampsia was significantly higher in the IGT (p=0.018) and GDM group (p=0.023), compared with the control group. CONCLUSION: Neonatal hyperbilirubinemia, as well as maternal preeclampsia were significantly elevated in the IGT group. The results obtained thus far demonstrate the possibility of the need for active perinatal care with therapeutic intervention in pregnant women with IGT.

During the last 30 years, there has been much advances in the understanding of pathogenisis of neonatal hyperbilirubinemia, but the risk of bilirubin encephalopathy are still remained for the high risk neonates. The mechanisms of bilirubin encephalopathy are not thouroughly understood. Various theories may explain bilirubin transport acoss the blood-brain barrier. Free bilirubin, not bound to albumin, can enter the brain. The permeability of the blood brain barrier to bilirubin or albuimin and bilirubin binding may play an important role in the bilirubin encephalopathy. Bilirubin binding ability of Korean infants, similar to American infants, is shown to be less than that of adults. Factors influencing bilirubin-albumin binding, such as acidosis, hypoxia, sepsis, hypothermia, hypoglycemia and immaturity should be considered for neonates at high risk of bilirubin encephalopathy. Free bilirubin is found to be significantly increased in preterm infants with low albumin level. Sulfisoxazole inhibits the bilirubin-albumin binding that resulted in increased free bilirubin concentrations even at low total bilirubin levels. Phenobarbital has no effects on bilirubin binding capacity of albumin. Phototherapy for 48 hours has no influence on bilirubin-albumin binding capacitiy and affinity. Auditory evoked repsonse (ABR) changes in the form of I, III, and IV wave reduction are associated with brainstem and cerebellum bilirubin deposition. Since early detection of bilirubin neurotoxicity is promising for improving outcome for high risk neonates, ABR and other electrophysiological measure will be useful.

OBJECTIVE: To determine whether late preterm twin neonates have a more favorable perinatal outcome than singleton late preterm neonates. METHODS: We studied 401 late preterm births between 34+0 and 36+6 weeks of gestation, from January 2011 to December 2014 in our institution. We compared the maternal and neonatal characteristics and perinatal outcomes between singleton and twin pregnancies. Perinatal outcomes included Apgar score, admission to the neonatal intensive care unit (NICU) or special care nursery, duration of NICU stay, and the rate of composite morbidity (antibiotic use, hypoglycemia, hypocalcemia, hyperbilirubinemia requiring phototherapy, respiratory support, and respiratory distress syndrome). RESULTS: A total of 289 neonates were in the singleton group and 112 in the twin group. The twin group showed smaller mean birth weight despite of longer gestational age at delivery. In addition, there were significant differences in the indication of delivery and cesarean section rate between the 2 groups. Overall, the risk of composite morbidity was similar between 2 groups (odds ratio, 1.4; 95% confidence interval, 0.8 to 2.4). CONCLUSION: Our findings suggest that late preterm twins do not show a more favorable outcome than singleton late preterm births.

PURPOSE: We evaluated three blood glucose self-monitoring for measuring whole blood glucose levels in preterm and low-birth-weight infants. METHODS: Between December 1, 2012 and March 31, 2013, 230 blood samples were collected from 50 newborns, who weighed, < or =2,300 g or were < or =36 weeks old, in the the neonatal intensive care unit of Eulji University Hospital. Three blood glucose self-monitoring (A: Precision Pcx, Abbott; B: One-Touch Verio, Johnson & Johnson; C: LifeScan SureStep Flexx, Johnson & Johnson) were used for the blood glucose measurements. The results were compared to those obtained using laboratory equipment (D: Advia chemical analyzer, Siemens Healthcare Diagnostics Inc.). RESULTS: The correlation coefficients between laboratory equipment and the three blood glucose self-monitoring (A, B, and C) were found to be 0.888, 0.884, and 0.900, respectively. For glucose levels< or =60 mg/dL, the correlation coefficients were 0.674, 0.687, and 0.679, respectively. For glucose levels>60 mg/dL, the correlation coefficients were 0.822, 0.819, and 0.839, respectively. All correlation coefficients were statistically significant. And the values from the blood glucose self-monitoring were not significantly different from the value of the laboratory equipment , after correcting for each device's average value (P>0.05). When using laboratory equipment (blood glucose < or =60 mg/dL), each device had a sensitivity of 0.458, 0.604, and 0.688 and a specificity of 0.995, 0.989, and 0.989, respectively. CONCLUSION: Significant difference is not found between three blood glucose self-monitoring and laboratory equipment. But correlation between the measured values from blood glucose self-monitoring and laboratory equipment is lower in preterm or low-birth-weight infants than adults.

OBJECTIVETo assess the diagnostic value of amplitude-integrated electroencephalography (aEEG) in predicting outcome of newborns who were at high risk for central nervous system without severe hypoxic-ischemic encephalopathy.

METHODSForty-two consecutive patients at risks for neurological disorders referred to our level-III NICU were prospectively enrolled in the study over a period of 3 years. They were classified on the basis of their primary diagnoses including hypoglycemic brain damage, meningoencephalitis, bilirubin encephalopathy, and metabolic disease. Clinical data were collected. Amplitude-integrated and raw EEG tracings were assessed for background pattern, sleep-wake cycling, and epileptiform activity. The neuromotor development of survivors was assessed by using the Infant Neurological International Battery (INFANIB).

RESULTThe characteristic of aEEG tracings in 42 infants showed continuous normal voltage (CNV)(n = 15), discontinuous voltage (DC)(n = 9), burst-suppression (BS) BS(+) (n = 6), BS(-)(n = 7), flat (FT, n = 5); mature sleep-wake cycling (SWC, n = 4), immature SWC (n = 14), no SWC (n = 24); 30 infants (71.4%) had electrical seizures: single seizure (n = 6); repetitive seizures (n = 7), and status epilepticus (SE) (n = 17).aEEG of 20 infants who had poor outcome showed FT (n = 5), BS(-)/SE (n = 6), BS(-)/ repetitive seizures (n = 1) , BS(+)/SE (n = 1), BS(+)/repetitive seizures (n = 1), DC/SE(n = 6). Chi-square analysis and Spearman rank correlation analysis showed the classification of aEEG background pattern, SWC and comprehensive score (score system was developed by evaluation of the above 3 variables) were correlated with the outcome of these infants at high neurological risks.

CONCLUSIONAmplitude-integrated electroencephalography can provide important information of the status of cerebral function in neonates at high neurological risk and help to predict their outcome.

BACKGROUND: Prader-Willi syndrome (PWS) is a congenital disorder, which is clinically characterized by a short stature, muscular hypotonia, hypogonadism, mental retardation and hyperphagia, leading to early childhood obesity. Impaired growth hormone (GH) secretion, hypogonadism, and obesity are common in patients with PWS. The purpose of this study was to find the effects of growth hormone treatment in patients with PWS. METHODS: Six patients with PWS confirmed by a genetic study were recruited, and treated with growth hormone(Eutropin(R))(0.8-1 IU/kg/week) divided into five or seven day doses per week for six months. The heights and weights of the subjects were evaluated. GH status were evaluated using the serum insulin-like growth factor (IGF)-I level, the L-dopa test, and insulin-induced hypoglycemia tess. Glucose metabolism was evaluated using the random serum glucose and HbA1c levels. RESULTS: GH was found to be deficient in 2 out of 6 subjects by the insulin test, in 3 out of 6 by the IGF-I level, and in 5 out of in 5 by the L-dopa test. After six months of GH treatment, the height percentile was increased and weight percentile decreased. The serum glucose and HbA1c levels remained unchanged. CONCLUSION: Six months of GH treatment in patients with PWS improved the height and degree of obesity. This study has shown the beneficial effects of GH treatment for patients with PWS, and without significant side effects.

Eight neonates with transient tricuspid insufficiency are presented which was confirmed clinical and two dimensional echocardiographic assessment. We found that two dimensional Doppler echocardiography was very useful in the detection of transient tricuspid insufficiency during neonatal age as noninvasive method. Transient tricuspid insufficiency is a clinical disorder in the newborn period caused by myocardial dysfunction, secondary to asphyxia with or without hypoglycemia and associated with right ventricular overloading caused by pulmonary hypertention. The clinical diagnosis was based on a history of perinatal distress, distinctive murmur, ECG changes, biochemical abnormalities and myocardial imaging. 1) The sex ratio of TTI was 1:1. 2) The average gestational age was 34 weeks and mean body weight was 2.06 Kg, respectably. 3) Major symptoms were dyspnea, cyanosis, and tachypnea. 4) Tricuspid regurgitation was detected from the lst day to the 4th day of the life and was improved from the 7th day to the 30th day of the life. 5) The peak velocity through tricuspid valve ranged from the 2.7 m/sec to 4.0 m/sec and the estimated right ventricular pressure ranged from 39 mmHg to 74 mmHg. 6) Associated diseases were neonatal hyperbilirubinemia (100%), prematurity (87.5%), atrial right to left shunt (87.5%), patent ductus arteriosus (75%), hyaline membrane disease (25%), and transient tachypnea of newborn (12.5%).

OBJECTIVES: To evaluate the clinical manifestations and perinatal outcomes of pregnancies complicated with gestational impaired glucose tolerance (GIGT) and gestational diabetes mellitus (GDM). METHODS: We performed 50gm oral glucose tolerance test (OGTT) for GIGT and GDM screening in 4,367 pregnant women at 24-28 weeks of gestation. In 1,010 women with plasma glucose level over 130mg/dl, 753 women underwent 100gm OGTTs at 28-32 weeks of gestation. According to the NDDG criteria, 113 cases with GIGT (single positive level of OGTT ; group 2), 125 cases with GDM (group 3), and 515 cases with control (group 1) were identified among the 753 cases. Retrospective review of outcome of these patients was performed. ANOVA and chi-square test were used to determine the statistical significance. RESULTS: The incidence of GIGT and GDM was 2.7%, 3.0%. The prepregnant body mass index (21.4+/- 3.0kg/m2, 21.3+/-2.8kg/m2, 23.2+/-4.1kg/m2), overweight of BMI over 26 (7.4%, 4.4%, 14.4%) and obesity of BMI over 30 (1.2%, 0.0%, 8.0%) was significantly higher in group 3 than group 1 (p<0.05). We defined poor maternal outcome as those suffering from any one of birth canal injury, hydramnios or oligohydramnios, preeclampsia, cesarean delivery due to cephalopelvic disproportion, dystocia, fetal distress. Group 3 showed most highest poor maternal outcome (22.3%, 28.3%, 39.2%, p<0.05). And we defined poor neonatal outcome as those suffering from any one of hyperbilirubinemia, hypoglycemia, congenital anomaly, admission to neonatal intensive care unit due to respiratory distress syndrome. Group 2 and group 3 showed poor neonatal outcome than group 1 (6.2%, 13.3%, 21.6%, p<0.05). CONCLUSION: Pregnancies complicated with GDM showed poor maternal and neonatal outcome, and GIGT experienced no adverse maternal outcomes but showed poor neonatal outcomes compared to normal pregnancy, and showed less correlation with obesity than GDM. Further study of pathophysiology and proper management of GIGT will be mandatory.
