PURPOSE: Congenital anomalies are known as a major cause of neonatal death with prematurity and birth injuries. We surveyed the incidence of congenital anomalies among livebirths and stillbirths delivered at our hospital, and detected in neonatal and postneonatal period. METHODS: The statistical study was done about congenital anomalies among 9,569 deliveries (9,438 livebirths and 131 stillbirths) at Ulsan University Hospital during the periods of 5 years from Jan 1992 to Dec 1996. We reviewed delivery and newborn record, OPD chart, admission chart retrospectively. We investigated the incidence of congenital anomaly according to each year, period, outcome of delivery, sex, birth weight, gestational age, maternal age, Apgar score, multiple pregnancy, and each system. RESULTS: 1) The overall incidence of congenital anomalies was 5.0% (481 cases) among 9,569 deliveries. The annual incidence was 4.5% in 1992, 5.1% in 1993, 5.2% in 1994, 5.8% in 1995, 4.7% in 1996. 2) The incidence of congenital anomalies detected in neonatal period was 3.5% (333 cases) and 1.5% (148 cases) in postneonatal periods. 3) The incidence of congenital anomalies was 4.9% among live births and 9.2% among stillbirths. 4) The incidence of congenital anomalies was 5.3% in male and 4.7% in female. 5) The incidence of congenital anomalies among the babies, below 2,500g of birth weight was 7.7%, between 2,500g and 3,999g was 4.7%, and over 4,000g was 6.8N. 6) The incidence of congenital anomalies among the babies, below 32 weeks of gestational age was 12.9%, between 32 weeks and 36 weeks was 7.4%, between 37 weeks and 41 weeks was 4.7%, and over 42 weeks was 5.1%. 7) The babies born to mothers younger than 20 years of age have anomalies in 7.1%, mother between 20 years of age and 35 years of age in 5.0%, and older than 35 years of age in 6.5%. 8) The incidence of congenital anomalies according to Apgar score among live births between 0 and 3 was 9.8%, between 4 and 6 was 6.0%, and between 7 and 10 was 5.0%. 9) The incidence of congenital anomalies according to multiple pregnancy was 8.6%. 10)The systems of congenital anomalies in order of incidence were as follows; The digestive system (25.6%), the cardiovascular system (22.1%), the genitourinary system (18.9%), the musculoskeletal system (15.5%), the skin and soft tissue (11.7%), the central nervous system (1.6%), the respiratory system (l%), the others (3.6%). CONCLUSIONS: Regular examination and screening on congenital anomaly is required from newborn period to infant and childhood. In view of these considerations, the incidence of congenital anomaly may be increased more than the past reports because of development of recent diagnostic techniques.

OBJECTIVE: This study aimed to evaluate attention, memory and executive function in patients with narcolepsy. METHODS: This study included 23 narcoleptic patients whose diagnosis were confirmed by the International Classification of Sleep Disorders(ICSD) at Chonnam National University Hospital Sleep Disorders Clinic or an other hospital in Korea, from 2005 to 2008, as well as 23 normal controls. All participants were given an IQ test for Korean-Wechsler Adult Intelligence Scale and several neuropsychological function tests (the d2 test for attention function, the Rey Complex Figure Test for nonverbal memory, the Korean-California Verbal Learning Test [K-CVLT] for verbal memory, and the Wisconsin Card Sorting Test for executive function). Clinical features of narcoleptic patients, including the frequency of excessive daytime sleepiness, cataplexy, sleep paralysis and hypnagogic hallucination, were investigated by a structured clinical interview administered by a neuropsychiatist. Excessive daytime sleepiness was evaluated by the Epworth sleepiness scale. RESULTS: Characteristic symptoms of narcolepsy observed in this study included excessive daytime sleepiness (n=23, 100.0%), cataplexy (n=19, 82.6%), hypnagogic hallucination (n=5, 21.7%) and sleep paralysis (n=12, 52.2%). In nocturnal polysomnographic findings, stage 2 sleep and REM latency were found to be significantly decreased in narcoleptic patients compared with the control group, and were accompanied by significant increases in stage 1 sleep. Narcoleptic patients had lower scores than the control group on total number, Total Number-Total Error, Concentration Performance and Fluctuation Rate on the d2 test, which measures attention. Also, there were significant differences between the performance of patient and control groups on the B list of the K-CVLT, which measures verbal memory. CONCLUSION: Narcoleptic patients showed decreased attention and verbal memory performance compared to the control group; however, in many areas, narcoleptic patients still demonstrated normal cognitive function.

Recently, next generation sequencing (NGS) has received attention as the ultimate genotyping method to overcome the limitations of capillary electrophoresis (CE)-based short tandem repeat (STR) analysis, such as the limited number of STR loci that can be measured simultaneously using fluorescent-labeled primers and the maximum size of STR amplicons. In this study, we analyzed 15 autosomal STR markers via the NGS method and evaluated their effectiveness in STR analysis. Using male and female standard DNA as single-sources and their 1:1 mixture, we sequentially generated sample amplicons by the multiplex polymerase chain reaction (PCR) method, constructed DNA libraries by ligation of adapters with a multiplex identifier (MID), and sequenced DNA using the Roche GS Junior Platform. Sequencing data for each sample were analyzed via alignment with pre-built reference sequences. Most STR alleles could be determined by applying a coverage threshold of 20% for the two single-sources and 10% for the 1:1 mixture. The structure of the STR in each allele was accurately determined by examining the sequences of the target STR region. The mixture ratio of the mixed sample was estimated by analyzing the coverage ratios between assigned alleles at each locus and the reference/variant ratios from the observed sequence variations. In conclusion, the experimental method used in this study allowed the successful generation of NGS data. In addition, the NGS data analysis protocol enables accurate STR allele call and repeat structure determination at each locus. Therefore, this approach using the NGS system will be helpful to interpret and analysis the STR profiles from singe-source and even mixed samples in forensic investigation.

Platelet-rich plasma (PRP) has been known to increase the rate and degree of bone formation by virtue of growth factors in concentrated platelets. Although its great healing effect on bone defect or pre-implantation site preparation in conjunction with bone substitute has been reported, the effect associated with implant is unknown. The purpose of this study was to investigate the effect of PRP on rapid osseointegration of endosseous dental implants in the rabbit tibiae. Twenty two adult female New Zealand white rabbits, weighing approximately 2.7-3.3kg, were used for this study. Twelve of the 22 animals were used for histomorphometric analysis and ten of the 22 were for removal torque test. Each animal received two implants in each tibia (two treated with PRP and two as control) and was given fluorochrome intramuscularly. For histomorphometric analysis, rabbits were divided into four groups according to the healing period. At 1 week, 2 weeks, 4 weeks and 8 weeks postoperatively, each three animals were sacrificed serially and the amount and rate of bone formation around dental implant were examined on the undecalcified sections under fluorescent microscope, polarized microscope and light microscope connected to a personal computer equipped with image analysis system. For removal torque test, rabbits were divided into two groups and removal torque tests were performed at 4 weeks, 10 weeks after implant placement. In total, 88 screw shaped, commercially pure titanium implants (Neoplant, Neobiotech, Seoul, Korea) were used in this study. Labeling pattern reflected differences of two groups in bone formation rate at each period. Histomorphometrically, PRP group showed significantly higher bone volume within threads compared to control group at 2 weeks (70.30+/-4.96% vs. 50.68+/-6.33%; P<.01) and 4 weeks (82.59+/-5.94% vs. 72.94+/-4.57%; P<.05). PRP group at 1, 2 and 4 weeks revealed similar degree of bone volume formation comparable to control group at 2, 4 and 8 weeks, respectively. On the other hand, while PRP group showed higher bone-implant contact (47.37+/-8.09%) than control group (33.16+/-13.47%) at 2 weeks, there were no significant differences between PRP group and control group for any experimental period. Removal torque values also showed no significant differences between PRP group and control group at any experimental period (P>.05). These findings imply that PRP could induce rapid, more bone formation around implant during early healing period and get faster secondary stability for reducing healing period, though it has not induced bone maturation enough to resist functional loading.
