PURPOSE: This study was done to compare breast feeding rates and factors influencing feeding practice between late preterm (34< or =GA<37) and preterm infants (GA<34). METHODS: A survey was done of 207 late preterm and 117 preterm infants in neonatal intensive care units (NICU) of 4 university hospitals in D city. Data were collected from July 2009 to June 2010 from 324 medical records in the NICU. Breast-feeding at home was checked either by telephone survey or questioning during hospital visits. RESULTS: Rate of breast feeding for late preterm infants was significantly lower than for preterm infants. There was no significant difference in breast-feeding at home. We found differences in factors influencing breast feeding between the two groups. Factors influencing feeding for late preterm infants were type of delivery, mothers' occupation, feeding type during hospitalization, time elapse from hospital discharge, total admission days, infant's body weight at first feeding and length of NPO (nothing by mouth). Factors influencing feeding for preterm infants were birth order, maternal disease and obstetric complications, and one-minute Apgar score. CONCLUSION: Results of the study show low rates of breast-feeding for late preterm infants indicating a need for breast-feeding education for mothers of these infants.

Bochdalek hernia through Bochdalek foramen, defect at the posterolateral side of the diaphragm is one of the congenital diaphragmatic hernias. It usually occurs in infants, but very rare in old age and also on the right side. We experienced the right-side Bochdalek hernia including kidney herniation in 68 years old man man ifested by hemoptysis. CT scan revealed diaphragmatic defect and herniated liver, colon and kidney. Thoracotomy was performed and the 10 cm-sized large defect was closed with patch. After then, the patient has been well without symptom.

Previously believed to solely play a supportive role in the central nervous system, astrocytes are now considered active players in normal brain function. Evidence in recent decades extends their contributions beyond the classically held brain glue role; it's now known that astrocytes act as a unique excitable component with functions extending into local network modulation, synaptic plasticity, and memory formation, and postinjury repair. In this review article, we highlight our growing understanding of astrocyte function and physiology, the increasing role of gliotransmitters in neuron-glia communication, and the role of astrocytes in modulating synaptic plasticity and cognitive function. Owing to the duality of both beneficial and deleterious roles attributed to astrocytes, we also discuss the implications of this new knowledge as it applies to neurological disorders including Alzheimer disease, epilepsy, and schizophrenia.

PURPOSE: The purpose of this study was to identify status and characteristics of patients who have been readmitted to ICU, and to analyze risk factors associated with the readmission to ICU within 48hours.METHODS: Data were collected from patient's electronic medical reports from one hospital in B city. Participants were 2,937 patients aged 18 years old or older admitted to the ICU. Data were analyzed using odd ratios (ORs) from multivariate logistic regressions.RESULTS: 2.2% of the 2,937 patients were early readmitted to ICU. Risk factors for early readmission to ICU were existence of respiratory disease, use of mechanical ventilator, and duration of hospitalization (longer).CONCLUSION: The assessment on the respiratory system of the patient who will be discharged from the ICU was identified as an important nursing activity. Therefore, the respiratory system management and education should be actively conducted. In addition, early ICU readmission may be prevented and decreased if a link was built to share the information on patient condition between the ICU and general wards.

Synapses are sites of high energy demand which are dependent on high levels of mitochondrial derived adenosine triphosphate. Mitochondria within synaptic structures are key for maintenance of functional neurotransmission and this critical biological process is modulated by energy metabolism, mitochondrial distribution, mitochondrial trafficking, and cellular synaptic calcium flux. Synapse loss is presumed to be an early yet progressive pathological event in Alzheimer disease (AD), resulting in impaired cognitive function and memory loss which is particularly prevalent at later stages of disease. Supporting evidence from AD patients and animal models suggests that pathological mitochondrial dynamics indeed occurs early and is highly associated with synaptic lesions and degeneration in AD neurons. This review comprehensively highlights recent findings that describe how synaptic mitochondria pathology involves dysfunctional trafficking of this organelle, to maladaptive epigenetic contributions affecting mitochondrial function in AD. We further discuss how these negative, dynamic alterations impact synaptic function associated with AD. Finally, this review explores how antioxidant therapeutic approaches targeting mitochondria in AD can further clinical research and basic science investigations to advance our in-depth understanding of the pathogenesis of AD.

Selective cervical nerve root block is executed for patients who have symptoms of cervical radiculopathy for diagnostic and therapeutic purposes. However several catastrophic complications caused by this procedure have been reported including neurological complications. A 43-year-old male received a C5 selective cervical nerve root block procedure due to continuous radiating pain even after cervical discectomy and interbody fusion was performed. At the time of the procedure, the contrast outline revealed reflux of the nerve root and epidural space. But after the procedure was performed, the patient experienced decreased sensation in the upper and low extremities as well as motor paralysis of both extremities. Our sspecting diagnosis was anterior spinal artery syndrome but both sensory and motor functions were subsequently recovered within a few hours after the procedure was completed. Due to the difficult nature of this case, we reported these complications and reviewed current literature related to this study.

Urinary hippuric acid was analyzed by gas chromatography/mass spectrometry method. A simple and economical derivatization procedure using excessive methanol in acidic condition was adopted to esterify hippuric acid. Quantitative analysis was performed with two internal standards, heptadecanoic acid and hydrocinnamic acid, to evaluate the derivatization procedure as an analytical method. Using the standard addition method, linear and reproducible calibration curves were obtained for both internal standards. Calibration experiment showed that good quantitative result could also be obtained with the calibration curve obtained without urine matrix. Recovery rates for the urine samples were in the range of 95.6~111.4%. Using hydrocinnamic acid as internal standard, analysis time could be reduced.

Ambient air monitoring(environmental monitoring) and biological monitoring of mixed organic solvents exposure have been used in exposure assessment of these compounds in the work environment. Environmental monitoring is more useful when assessing low level exposure to these compounds. The specific objectives of this study were to measure air organic solvent levels in the work environment, to test the agreement of items measured in this study with items which have been reported to the administrative agency, and finally to evaluate the appropriateness of environmental monitoring items. The study subjects were 13 small companies in which less than 300 employees were working and presumably exposed to mixed organic solvents(e.g. automotive repair and painting, 6; textile dyeing, 2; printing, 2; electronics, etc, 3). Personal air samplings were performed by the flow-lite sampling pump(MSA) and the 600mg charcoal tube with air velocity of 100ml/min for qualitative analysis and 2l/min for quantitative analysis. Samples were analysed by gas chromatography/mass spectrometry(Hewlett-Packard 5890/5970). High levels of toluene, n-hexane, and MIBK were detected in most study companies and low levels of ethylbenzene, xylene, n-butylacetate were also detected. When these measured items were compared with those of reported items, only 6 of 13 companies showed relatively good agreement between them. Two companies failed to report items exceeding the limit value. In conclusion, qualitative analysis of ambient air organic solvents seemed to be as important as quantitative analysis of these compounds and a periodic evaluation of monitoring items reported to the administrative agency should be required.

OBJECTIVE: The purpose of this study was to evaluate the impact of pelvic organ prolapse (POP) repair on overactive bladder (OAB) symptoms in women with POP and the effect of baseline POP severity on improvement in OAB after surgical repair of POP. And we also tried to identify any preoperative factors for persistent postoperative OAB symptoms. METHODS: A total of 87 patients with coexisting POP and OAB who underwent surgical correction of POP were included and retrospectively analyzed and postoperative data was obtained by telephone interview. OAB was defined as an affirmative response to item no. 15 (urinary frequency) and item no. 16 (urge incontinence) of the Pelvic Floor Distress Inventory. POP severity was dichotomized by Pelvic Organ Prolapse Quantification stage 1 to 2 (n=22) versus stage 3 to 4 (n=65). RESULTS: OAB symptoms were significantly improved after surgical treatment (P<0.001). But there was no significant differences in postoperative improvement of frequency and urge incontinence between stage 1 to 2 group versus stage 3 to 4 group. Preoperative demographic factors (age, parity, and POP stage) were not significantly related to persistent postoperative OAB symptoms. CONCLUSION: Women with coexisting POP and OAB who undergo surgical repair experience significant improvement in OAB symptoms after surgery, but severity of POP had no significant difference in improvement of OAB symptoms. Postoperative persistent OAB symptoms were not related to age, parity, body mass index, and POP stage.

OBJECTIVE: To investigate the relationship between serum creatine kinase (CK) level and pulmonary function in Duchenne muscular dystrophy (DMD). METHODS: A total of 202 patients with DMD admitted to the Department of Rehabilitation Medicine, Gangnam Severance Hospital were enrolled from January 1, 1999 to March 31, 2015. Seventeen patients were excluded. Data collected from the 185 patients included age, height, weight, body mass index, pulmonary function tests including forced vital capacity (FVC), peak cough flow, maximal expiratory pressure (MEP), and maximal inspiratory pressure (MIP), and laboratory measurements (serum level of CK, CK-MB, troponin-T, and B-type natriuretic peptide). FVC, MEP, and MIP were expressed as percentages of predicted normal values. RESULTS: Serum CK activities were elevated above normal levels, even in the oldest DMD group. Serum CK level was strongly correlated with pulmonary functions of sitting FVC (p<0.001), supine FVC (p<0.001), MIP (p=0.004), and MEP (p<0.001). CONCLUSION: Serum CK level is a reliable screening test even in patients with advanced DMD, and is a strong predictor of pulmonary functions.
