PURPOSE: Routine screening for toxoplasmosis, rubella, cytomegalovirus (CMV), and herpes simplex virus (TORCH) in intrauterine growth restriction (IUGR) and small for gestational age (SGA) neonates has become a common practice. However, the incidence of TORCH varies across countries, and the cost of TORCH testing may be disadvantageous compared to disease-specific screening. To evaluate the efficacy of TORCH screening, the medical charts of IUGR or SGA neonates born in a single institution in Bucheon, Korea from 2011 to 2015 were reviewed. METHODS: The clinical data of the 126 IUGR or SGA neonates were gathered, including gestational age, Apgar scores, neonatal sonographic findings, chromosome study, morbidities, developmental follow-up, and growth catch-up. Maternal factors including underlying maternal disease and fetal sonography were collected, and placental findings were recorded when available. TORCH screening was done using serum IgM, CMV urine culture, quantification of CMV DNA with real-time polymerase chain reaction, and rapid plasma reagin qualitative test for syphilis. Tests were repeated only for those with positive results. RESULTS: Of the 119 TORCH screenings, only one was positive for toxoplasmosis IgM. This result was deemed false positive due to negative IgM on repeated testing and the absence of clinical symptoms. CONCLUSION: Considering the incidence and risk of TORCH in Korea, the financial burden of TORCH screening, and the single positive TORCH finding in our study, we suggest disease-specific screening based on maternal history and the clinical symptoms of the neonate. Regarding CMV, which may present asymptomatically, universal screening may be appropriate upon cost-benefit analysis.

PURPOSE: The aim of this study was to evaluate the efficacy of pamidronate therapy in children and adolescents with secondary osteoporosis. METHODS: Nine patients (7 males, 2 females, 13.2 +/- 2.5 years, 10.1-17.4 years) with secondary osteoporosis who had a history of severe bone pain and/or fracture were enrolled. Intravenous pamidronate 1.5 mg/kg (0.5 mg/kg for 3 consecutive days) was given every 6 to 8 weeks for 0.86 +/- 0.15 years (6 or 8 cycles). Bone mineral density (BMD) in lumbar spine and femoral neck and their Z-scores were measured before treatment, after the fourth and last cycle (sixth or eighth cycle). RESULTS: Underlying diseases were as follows; neurofibromatosis type 1 (n = 2), epilepsy with/without cerebral palsy (N=2), autoimmune disease treated with steroid (n = 2), hematologic malignancy (n = 3). Bone pain was relieved in most of the patients after the first cycle of treatment, and no more fracture occurred thereafter. There was a significant increase in BMD Z-score of the lumbar spine and femoral neck after the last cycle of therapy, compared to baseline values (from -3.91 +/- 1.79 to 1.86 +/- 1.18, in L1-4 and -3.71 +/- 1.83 to -2.53 +/- 1.77 for femoral neck; P = 0.008 and 0.011, respectively). However, there was no significant change in BMD Z-scores between the fourth cycle and the last cycle. Fever developed in 7 out of 9 patients (77.8%), which was relieved by antipyretics. Total serum levels of calcium and phosphorus were significantly decreased (calcium, P = 0.008; phosphorus, P = 0.015) after pamidronate therapy, and three of them experienced symptomatic hypocalcemia during the first cycle. The growth velocity was normal during follow-up periods (mean, 4.47 +/- 1.69 years; range, 1.05 to 6.77 years). CONCLUSION: In conclusion, pamidronate can be administered to the patients with secondary osteoporosis, relieving the symptoms and signs effectively and safely. However, its side effects should be monitored during treatment.

PURPOSE: Short sleep duration is associated with obesity. Urinary 6-sulfatoxymelatonin (6-OHMS), the principal metabolite of melatonin, is closely related with sleep. We evaluated the difference in urinary 6-OHMS levels between obese girls and normal weight girls, and the relationship of urinary 6-OHMS with other hormones regulating body weight and metabolism. METHODS: A total of 79 girls (6.3 to 12.4 years) were included in this study, of whom 34 were obese; 15, overweight; and 30, normal-weight. We examined their pubertal status and bone age. Fasting serum levels of total ghrelin, leptin, insulin, and first morning urinary 6-OHMS were measured. Homeostatic model assessment-insulin resistance (HOMA-IR) was calculated from the fasting insulin and glucose levels. RESULTS: There was no significant difference in the creatinine adjusted 6-OHMS levels between the obese girls and the control group. Urinary 6-OHMS did not show any correlations with body mass index (BMI), BMI percentile, total ghrelin, leptin, and HOMA-IR. Negative correlations were found between urinary 6-OHMS levels and chronological and bone ages. CONCLUSION: Our results suggest that melatonin production is not reduced consistently in obese girls.

Background:
There are many models for predicting diabetes mellitus (DM), but their clinical implication remains vague. Therefore, we aimed to create various DM prediction models using easily accessible health screening test parameters.
Methods:
Two sets of variables were used to develop eight DM prediction models. One set comprised 62 easily accessible examination results of commonly used variables from a tertiary university hospital. The second set comprised 27 of the 62 variables included in the national routine health checkups. Gradient boosting and random forest algorithms were used to develop the models. Internal validation was performed using the stratified 10-fold cross-validation method.
Results:
The area under the receiver operating characteristic curve (ROC-AUC) for the 62-variable DM model making 12-month predictions for subjects without diabetes was the largest (0.928) among those of the eight DM prediction models. The ROC-AUC dropped by more than 0.04 when training with the simplified 27-variable set but still showed fairly good performance with ROC-AUCs between 0.842 and 0.880. The accuracy was up to 11.5% higher (from 0.807 to 0.714) when fasting glucose was included.
Conclusion
We created easily applicable diabetes prediction models that deliver good performance using parameters commonly assessed during tertiary university hospital and national routine health checkups. We plan to perform prospective external validation, hoping that the developed DM prediction models will be widely used in clinical practice.

Hypoglycemia is one of the severe complications of diabetes. To prevent hypoglycemia, an emphasis is placed on maintaining an appropriate balance between nutrition, activity, and treatment, which can be achieved by the repetition of self-trials based on self-monitoring. Clinicians routinely focus on patients’ contribution, including timely intake of an adequate amount of carbohydrates, physical activity, antidiabetic medication, and abstinence from alcohol. Recently, many guidelines have highlighted the importance of clinicians’ factors and recommend individualized treatments according to lifestyle patterns and specific needs following the de-intensification of treatment. The optimal value of hemoglobin A1c (HbA1c) levels for blood glucose level regulation remains controversial among countries, but it generally does not exceed 8.0%. In populations that are at a risk of hypoglycemia, such as the older adults, it is advisable to adjust the target blood glucose level to less than 8.0%. Meanwhile, a blood glucose level of 7.0%–7.5% is generally recommended for healthy older adults. If the expected lifetime is shorter than 10 years or in patients with chronic kidney disease and severe cardiovascular disease, the HbA1c level target can be increased to 7.5%–8.0%. For even shorter lifetime expectancy, the target can be adjusted up to 8.0%–9.0%. To prevent hypoglycemia, the target blood glucose level needs to be adjusted, particularly in older adult patients. Ultimately, it is important to identify the maximum blood glucose levels that do not cause hypoglycemia and the minimum blood glucose levels that do not cause hyperglycemia-associated complications.

PURPOSE: Capillary hemangiomas occur more frequently in preterm infants. We aimed to describe the clinical course of capillary hemangiomas in preterm infants. METHODS: The records of preterm infants with a gestational age (GA) of <35 weeks who were admitted to two tertiary neonatal intensive care units from January 2004 to December 2013 and had capillary hemangiomas were reviewed retrospectively. Subgroup analysis of between infants of GA <30 weeks and GA 30-34+6 weeks were done and ad hoc analysis comparing study population and matched preterm infants without hemangioma for investigation of differences in clinical characteristics. RESULTS: Of the 2,772 preterm infants, 112 (4%) infants developed capillary hemangiomas. The majority (91.9 %) of them had a solitary hemangiomas with the trunk was the most commonly involved site (43%). Three quarters of the patients were treated with topical corticosteroid, propranolol or laser treatment. When we divided this population as who were born before or after GA 30 weeks, there was no difference at postmenstrual age (PMA) of onset of capillary hemangiomas (median [IQR], 36(+4) [30(+5)-40(+5)] vs. 36+2 [33(+6)-41(+1)] weeks, P = 0.275). The age at involution of capillary hemangiomas was also not differ between two groups (median [IQR], 7.75 [3.75-12.25] vs. 7.5 [4-13.75] months, P=0.425). There were no statistical differences between preterm infants with capillary hemangiomas and their age, weight and sex matched control preterm infants without hemangiomas in the neonatal and maternal factors. CONCLUSION: The development of capillary hemangiomas occurred at approximately 36 to 37 weeks of PMA regardless of prematurity in preterm infants. Capillary hemangiomas of preterm infants resolved spontaneously and disappear completely by around 7 months of corrected age.

Obesity and its related factors are known to suppress the secretion of growth hormone (GH). We aimed to evaluate the influence of body mass index (BMI) on the peak GH response to provocative testing in short children without GH deficiency. We conducted a retrospective review of medical records of 88 children (2-15 yr old) whose height was less than 3 percentile for one's age and sex, with normal results (peak GH level > 10 ng/mL) of GH provocative testing with clonidine and dopamine. Peak stimulated GH level, height, weight, pubertal status and serum IGF-1 level were measured. Univariate analysis showed that the BMI standard deviation score (SDS) correlated negatively with the natural log (ln) of the peak stimulated GH level (ln peak GH). BMI SDS did not correlate significantly with sex, age, pubertal status, or ln IGF-1 level. BMI SDS correlated negatively with ln peak GH level induced by clonidine but not by dopamine. In stepwise multivariate regression analysis, BMI SDS was the only significant predictor of ln peak GH level in the combination of tests and the clonidine test, but not in the dopamine test. In children without GH deficiency, BMI SDS correlates negatively with the peak GH level. BMI SDS should be included in the analysis of the results of GH provocation tests, especially tests with clonidine.

Weinstein et al. first described the HELLP (hemolytic anemia, elevated liver enzymes, and low platelets) syndrome in 1982. The incidence of HELLP syndrome is 0.2~0.6% in normal pregnant women and 4~12% in women with preeclampsia. This syndrome is accompanied by serious medical complications, including hepatic and renal failure, coagulopathy, hypertension, and pulmonary edema. Retinal detachment is an unusual, but well documented, complication of hypertensive disorder in pregnancy affecting 0.2~2% of patients with severe preeclampsia and 0.9% of patients with HELLP syndrome. This paper reports on a patient with HELLP syndrome accompanied by retinal detachment who recovered after controlling the blood pressure and receiving systemic steroids.

PURPOSE: We evaluate respiratory morbidities in infants beyond 35 weeks of gestation born via elective cesarean section by gestational age. METHODS: This is a retrospective study of 443 infants who were born at Seoul National University Hospital by elective cesarean section beyond 35 weeks of gestation from January 2011 to December 2012. We compared respiratory morbidities in four groups classified by gestational age (35(+0)-36(+6) weeks, 37(+0)-37(+6) weeks, 38(+0)-38(+6) weeks, 39(+0)-40(+6) weeks). RESULTS: There were significantly lower Apgar scores in the late-preterm infant group (35-36 weeks) compared to other term infant groups and the proportion of infants born from mothers with preeclampsia gradually decreased as gestational age increased. There were significant differences in O2 supplement, duration of O2 (>24 hours), checked chest radiography, transient tachypnea of newborn (TTN), transfer to neonatal intensive care unit (NICU), endotracheal intubation, and ventilator uses including nasal continuous positive airway pressure in four groups (P<0.05). By logistic regression analysis, compared to births at 38 weeks, births at 35-36 weeks and at 37 weeks were associated with an increased risk of respiratory morbidities [odds ratios (OR) and 95% confidence intervals (CI) for births at 35-36 weeks, 122.5 (17.4-863.4) for TTN; 54.0 (10.1-289.4) for transfer to NICU; 99.5 (14.9-666.2) for ventilator apply; OR and 95% CI for births at 37 weeks, 8.8 (1.6-50.1) for TTN; 5.3 (1.1-24.7) for transfer to NICU; 8.4 (1.5-47.7) for ventilator apply; P<0.05]. There were no significant differences in respiratory morbidities between births at 38 weeks and births at 39-40 weeks. CONCLUSION: Postponing the timing of elective cesarean section to beyond 38 weeks of gestation would be helpful in reducing the neonatal respiratory morbidities.
