PURPOSE: Ghrelin stimulates the secretion of growth hormone and other pituitary hormones, and has orexigenic effects. It may have a physiologic role in fetal and neonatal growth. Leptin secreted by the adipocytes reflects fat mass in infants as well as adults. The aim of this study was to evaluate the relation of cord blood ghrelin and leptin levels to body weight(BW), body mass index(BMI), insulin-like growth factor-I(IGF-I) and insulin-like growth factor binding protein-3(IGFBP-3) levels in appropriate for gestational age(AGA) newborns. METHODS: Sixty healthy AGA newborns(31 males and 29 females, gestational age[GA] 34-42 weeks) were included in this study, whose BW and BMI were measured at delivery. Umbilical cord venous blood samples were withdrawn, and ghrelin and leptin were measured by radioimmunoassay. Cord blood IGF-I and IGFBP-3 were determined by immunoradiometric assay. RESULTS: The mean levels of ghrelin were inversely correlated with BW(r=-0.29, P<0.05) and GA (r=-0.28, P<0.05), but were not affected by gender. The mean levels of leptin levels showed positive correlation with BW(r=0.44, P<0.01), GA(r=0.36, P<0.01), and BMI(r=0.28, P<0.05). The leptin levels of females were higher than those of males. There was no gender difference in leptin levels in neonates under GA 37 weeks. However, the leptin levels of females were higher than those of males (P<0.01) in newborns with GA 37 weeks or over. There was no correlation between ghrelin and leptin levels. Ghrelin and leptin levels showed no relations to cord blood IGF-I and IGFBP-3 levels. CONCLUSION: These data suggest that cord blood ghrelin may have an inverse correlation with BW in AGA newborns, and leptin levels are positively correlated with BW and fat mass. Further study of ghrelin concentrations in cord blood is necessary to elucidate the physiological and pathological roles of ghrelin during the fetal and neonatal periods.

Acute A viral hepatitis is a mild, self-limiting disease of liver and acute renal failure (ARF) is a rare complication. We report two cases of chronic renal failure (CRF) in nonfulminant acute A viral hepatitis and ARF. A 40-year-old man was admitted with ARF and acute A viral hepatitis, and underwent temporary hemodialysis therapy. The renal biopsy showed acute tubular necrosis with tubulointerstitial nephritis. At 13 months after discharge serum creatinine was 1.33 mg/dL and protein-creatinine ratio of spot urine was 0.47 (mg/mg Cr). The second case was a 28-year-old man and was managed conservatively. At discharge the serum creatinine was 3.14 mg/dL and the urinalysis showed hematuria, and protein-creatinine ratio 0.56 (mg/mg Cr). Thirty-nine months after discharge, the creatinine was 1.23 mg/dL, the urinalysis showed persistent nephritis findings and the protein-creatinine ratio 1.28. Kidney biopsy revealed the membranous glomerulopathy with mild tubulointerstitial nephritis, and all of findings suggested the systemic disease-associated secondary glomerulopathy. To our knowledge our case is the first one of chronic glomerulapathy that is confirmed by kidney biopsy.

PURPOSE: This study aimed to evaluate the autonomic imbalance in syncope by comparing the baseline heart rate variability (HRV) between healthy children and those with vasovagal syncope. METHODS: To characterize the autonomic profile in children experiencing vasovagal syncope, we evaluated the HRV of 23 patients aged 7-18 years and 20 healthy children. These children were divided into preadolescent (<12 years) and adolescent groups. The following time-domain indices were calculated: root mean square of the successive differences (RMSSD); standard deviation of all average R-R intervals (SDNN); and frequency domain indices including high frequency (HF), low frequency (LF), normalized high frequency, normalized low frequency, and low frequency to high frequency ratio (LF/HF). RESULTS: HRV values were significantly different between healthy children and those with syncope. Student t test indicated significantly higher SNDD values (60.46 ms vs. 37.42 ms, P=0.003) and RMSSD (57.90 ms vs. 26.92 ms, P=0.000) in the patient group than in the control group. In the patient group, RMSSD (80.41 ms vs. 45.89 ms, P=0.015) and normalized HF (61.18 ms vs. 43.19 ms, P=0.022) were significantly higher in adolescents, whereas normalized LF (38.81 ms vs. 56.76 ms, P=0.022) and LF/HF ratio (0.76 vs. 1.89, P=0.041) were significantly lower in adolescents. In contrast, the control group did not have significant differences in HRV values between adolescents and preadolescents. CONCLUSION: The results of this study indicated that children with syncope had a decreased sympathetic tone and increased vagal tone compared to healthy children. Additionally, more severe autonomic imbalances possibly occur in adolescents than in preadolescents.

This study evaluated the surgical outcome and complications of phacoemulsification and the implantation of an acryl foldable intraocular lens (IOL) with a squared edge in dogs with cataracts. Thirty-two eyes from 26 dogs were examined. The mean follow up period was 75.9 days ranging from 23 to 226 days. The complications after phacoemulsification were posterior capsular opacity (PCO) around the IOL (n = 11), ocular hypertension (n = 4), focal posterior synechia (n = 4), hyphema (n = 3) and corneal ulcer (n = 2). The complications associated with the IOL were decenteration of the optic (n = 2) and ventral haptic displacement (n = 1). Most cases of PCO were found only around the margin of the IOL, and all eyes had vision during the observation period. In conclusion, the implantation of an acryl-foldable lens with a squared edge at the time of phacoemulsification is an effective method for preserving the central visual field of dogs with cataract.

BACKGROUND: Altered airway mucosal osmolarity is an underlying mechanism of bronchoconstrictive response to both exercise and hypertonic saline (HS). The purpose of this study was to examine whether the osmotic challenge test using HS could predict the exercise-induced bronchospasm (EIB) in asthma. METHODS: Thirty-six consecutive young male patients with asthma visited Chonnam National Univertisy Hospital underwent bronchial challenge tests using 4.5% HS, exercise (>24 hours later), and methacholine (MCh). The relationship in the responses between HS and exercise was observed in comparison with that between MCh and exercise. RESULTS: The maximal fall in forced expiratory volume in one second following exercise was significantly higher in the HS-responders (n=19) than that in the HS-nonresponders (n=17)(35.9 +/- 4.1% vs. 17.9 +/- 2.7%, p<0.001). There was a significant correlation between the severity of EIB and HS-airway hyperresponsiveness (AHR). Compared with the MCh-AHR test in diagnosing for EIB, the HS-AHR test showed a higher specificity (71.4% vs. 42.9%), but a lower sensitivity (58.6% vs. 89.7%) and a lower negative predictive value (29.4% vs. 50.0%). At the cutoff value for moderate AHR, the MCh-AHR test had specificity comparable with and predictive values higher than those of the HS-AHR test. CONCLUSION: The HS-AHR test was more specific than the MCh-AHR test, but less sensitive and had poor negative predictive value precluding from use of it as a screening test for EIB. The MCh-AHR test at the cutoff value for moderate AHR may be more useful in predicting EIB in asthma.

OBJECTIVES: Otitis media (OM) is an infectious disease that affects all age brackets. Aural discharge is a typical symptom, occurring in all subtypes of OM. We have compared the identity and antibiotic sensitivity of bacteria isolated from aural discharges of adults and children with various types of OM, including acute OM (AOM), OM with effusion (OME), chronic OM (COM), and cholesteatomatous OM (CSOM). METHODS: The study involved 2,833 patients who visited five tertiary hospitals between January 2001 and December 2010 and were diagnosed with AOM, OME, COM, or CSOM. The patients were divided into a pediatric group and an adult group, and the distribution of cultured bacteria and their antibiotic sensitivity were compared in the two groups. RESULTS: Bacterial detection rates were higher in adults than in children with OME and COM (P=0.000 each). The majority of the bacteria cultured from patients with AOM and OME bacteria were methicillin-susceptible Staphylococcus aureus (MSSA) and Streptococcus pneumoniae. Bacteria cultured from children were more susceptible to antibiotics (P=0.002) and had higher antibiotic sensitivity (P=0.001) than were bacteria cultured from adults. The majority of bacteria culture from patients with COM and CSOM were MSSA and pathogenic Pseudomonas aeruginosa. The frequency of methicillin-resistant Staphylococcus aureus was significantly higher in adults than in children, and more strains of bacteria isolated from adults were sensitive to the antibiotics septrin, vancomycin, and teicoplanin. CONCLUSION: Bacteria cultured from children were more susceptible to antibiotics and had higher antibiotic sensitivity than did bacteria cultured from adults.

OBJECTIVES: We have analyzed the correlation between the House-Brackmann (HB) scale and Facial Nerve Grading System 2.0 (FNGS 2.0) in patients with Bell palsy, and evaluated the usefulness of the new grading system. METHODS: Sixty patients diagnosed with Bell palsy from May 2009 to December 2010 were evaluated using the HB scale and FNGS 2.0 scale during their initial visit, and after 3 and 6 weeks and 3 months. RESULTS: The overall intraclass correlation coefficient (ICC) was 0.908 (P=0.000) and the Spearman correlation coefficient (SCC) was 0.912 (P<0.05). ICC and SCC displayed differences over time, being 0.604 and 0.626, respectively, at first visit; 0.834 and 0.843, respectively, after 3 weeks; 0.844 and 0.848, respectively, after 6 weeks; and 0.808 and 0.793, respectively, after 3 months. There was a significant difference in full recovery, depending on the scale used (HB, P=0.000; FNGS 2.0, P<0.05). The exact agreements between regional assessment and FNGS 2.0 for the mouth, eyes, and brow were 72%, 63%, and 52%, respectively. CONCLUSION: FNGS 2.0 shows moderate agreement with HB grading. Regional assessment, rather than HB grading, yields stricter evaluation, resulting in better prognosis and determination of grade.

PURPOSE: The incidence of methicillin-resistant Staphylococcus aureus (MRSA) infection has increased in children and in neonates, and is particularly associated with frequent use of central venous catheter in very low birth weight (VLBW) infants. It is known that the morbidity and mortality of MRSA infection are low in neonates, as compared with adults. The objective of this study was to examine the difference in clinical characteristics between VLBW infants that survived and those that did not, a catheter-related bloodstream infection (CRBSI) of MRSA. METHODS: Thirty-four VLBW infants had laboratory-confirmed bloodstream infection with S. aureus. We examined the incidence, mortality and morbidity of CRBSI, and predictive factors associated with mortality. RESULTS: Twenty-six infants had same pathogen (24 MRSA, 2 Methicillin-sensitive Staphylococcus aureus) in the blood and in the catheter tip. Eight infants (25.8%) died in the CRBSI and they all had MRSA blood infections. Sex ratio, gestational age, duration between blood collection and identification of pathogens, and WBC and platelet count were not significantly different between patients that died from and patients that survived CRBSI of MRSA. C-reactive protein (CRP) was significantly higher in VLBW infants that died. Mean age of onset and hospital day was earlier (9.1+/-6.6 vs. 26.9+/-20.2; P=0.005) and shorter for patients that died (10.1+/-7.0 vs. 73.0+/-32.4; P=0.000). Two survivors had complications of pyogenic arthritis of the lower extremities and soft tissue infection, respectively. CONCLUSION: Mortality of CRBSI was likely to be high in VLBW infants and might be anticipated by CRP and early onset of disease.

OBJECTIVE: To determine the efficacy of ultrasonogram in the detection of cornual pregnancy and the factors that might be affected on early diagnosis. METHOD: We studied 26 cases which were diagnosed as a cornual pregnancy from Jan, 1, 2000 to Dec, 31, 2004 at department of Obstetrics and Gynecology, St. Vincent's Hospital, the Catholic University of Korea. We compared two groups about clinical characteristics and outcomes. One group (A group) was diagnosed as cornual pregnancy before beginning of treatment, another group (B group) was not diagnosed as cornual pregnancy until operation. RESULTS: A group was 8 cases (30.8%) and B group was 18 cases (69.2%). There were no significant differences in age (33.0+/-6.21 years : 31.0+/-5.82 years), duration of amenorrhea (7.32+/-1.07 weeks : 8.90+/-5.44 weeks), previous cesarian section history (25.0% : 27.8%), present myoma (12.5% : 11.1%) and abdominal pain (50% : 77.78%), vaginal bleeding (50% : 55.6%), shock (0% : 27.8%) between two groups. There were significant differences in parity (1.63+/-0.74 : 1.0+/-0.77, p=0.032), number of abortions (2.25+/-1.16 : 1.11+/-1.18, p=0.016), previous history of ectopic pregnancy (37.5% : 0%, p=0.022). Of the method of treatments, only cornual resection (50% : 94.4%) showed significant differences between two groups. CONCLUSION: 30.8% of cornual pregnancy was early diagnosed by ultrasonogram. The important early detective factors for cornual pregnancy might be parity, previous ectopic pregnancy history and abortion history. Therefore if the patient has the previous ectopic pregnancy and abortion history, she can visit early to the hospital and the doctors do pay attention to the possibility of cornual pregnancy.

BACKGROUND: Changes in airway mucosal osmolarity are an underlying mechanism of bronchoconstrictive responses to exercise and hypertonic saline (HS). The purpose of this study was to examine whether an osmotic challenge test using HS can predict exercise-induced bronchospasm (EIB) in asthma patients. METHODS: Thirty-six young male asthmatic patients underwent bronchial challenge tests based on 4.5% HS, exercise (> 24h later), and methacholine (MCh) at the Chonnam National University Hospital. The relationships between responses to HS and exercise, and between MCh and exercise were evaluated. RESULTS: The maximal fall in forced expiratory volume in one second following exercise was significantly higher in the HS-responders (n=19) than in the HS-nonresponders (n=17, 35.9+/-4.1% vs. 17.9+/-2.7%, p< 0.001), and there was a significant correlation between the severity of EIB and HS-airway hyperresponsiveness (AHR). When compared with the MCh-AHR test in terms of predicting EIB, the HS-AHR test showed higher specificity (71.4% vs. 42.9%), but a lower sensitivity (58.6% vs. 89.7%) and negative predictive value (29.4% vs. 50.0%). At the moderate AHR cutoff value, the MCh-AHR test had a specificity that was comparable with and predictive values that were higher than those of the HS-AHR test. CONCLUSIONS: The HS-AHR test was more specific than the MCh-AHR test, but was less sensitive and had a poorer negative predictive value, which in combination preclude the use of the HS-AHR test as a screening tool for EIB. The MCh-AHR test had a cutoff value for moderate AHR that may be more useful for predicting EIB in asthmatic patients.
