BACKGROUND: Because desflurane can cause airway irritability when used to induce anesthesia, drugs aimed at reducing airway irritability. This study investigated the possible differences between lidocaine and alfentanil on the decrease in the airway irritability during desflurane inhaled induction. METHODS: 75 patients (25 in each groups) were assigned randomly to induce anesthesia with inhaled desflurane. The breathing circuit was primed with desflurane 6% in 50% O2 and 50% N2O. After pretreatment with 2% lidocaine (1 mg/kg), or alfentanil (10microgram/kg), or saline (7 ml) intravenously 2 minutes before inducing anesthesia, each patient breathed the gas mixture through a tight fitting facemask. The time to loss of consciousness, cough, laryngospasm, excitatory movement and hemodynamics were checked before and after inhalation. RESULTS: The time to loss of consciousness, cough and excitatory movement were lower significantly between in the control group and other groups, but there was no difference between the 2% lidocaine and alfentanil groups. The blood pressure and heart rate were lower in the alfentanil group, but the heart rate was similar. CONCLUSIONS: These results explain that intravenous 2% lidocaine appears to be useful. However, Intravenous alfentanil can also reduce the airway irritability and stabilize the hemodynamics significantly when desflurane is used to induce anesthesia.

BACKGROUND: Propofol increases the risk of bradycardia compared with other anesthetics. This paper reports the heart rate response to intravenous atropine during propofol and enflurane anesthesia. METHODS: Sixty patients undergoing a transabdominal hysterectomy under general anesthesia were randomly assigned to two groups: the propofol group and the enflurane group. All the patients received midazolam 2 mg intramuscularly and were then anesthetized with propofol or enflurane. The blood pressure and heart rate were taken at 1 min intervals for 10 min after a bolus injection of atropine 5microgram/kg. RESULTS: In the enflurane group, the systolic blood pressure and heart rate were increased significantly at 1, 2 and 3 min after the atropine injection (P<0.05). When the two groups were compared, the heart rate in the enflurane group was significantly higher at 1, 2 and 3 min after atropine injection than in the propofol group (P<0.05). CONCLUSIONS: The heart rate response to intravenous atropine during propofol anesthesia is attenuated compared with enflurane anesthesia.

BACKGROUND: This study assessed the changes in the heart rate variability (HRV) indices, which are used to measure the autonomic nervous system function during general anesthesia (GA), and compared the result of the awake state. METHODS: Patients undergoing an explo-laparotomy were anesthetized with either isoflurane (Group I, n = 20) or sevoflurane (Group S, n = 20) added to a mixture of nitrous oxide and oxygen. Frequency-domain analysis of the HRV indices using fast Fourier transformation (FFT) resulted in a power spectrum with a very low (VLF), low (LF), and high frequency (HF) and calculated normalized LF (nuLF), normalized HF (nuHF), and LF/HF ratios before and after GA. Time-domain analysis was performed and the pNN50 (proportion of successive RR intervals [RRI] > 50 ms in relation to the total RRI), RMSSD (root mean square of the successive differences in the RRI), standard deviation 1 (SD1) and standard deviation 2 (SD2) from the Poincare plots, HRV triangular index, and TINN (triangular interpolation of NN interval histogram) were also calculated before and after GA. RESULTS: The VLF, LF, HF, nuLF, and LF/HF ratio during GA decreased by 45.2, 95.1, 83.1, 27.3, and 17.4%, respectively, compared with the awake state. However, the nuHF significantly increased. The RMSSD, pNN50, SD1, SD2, HRV triangular index, and TINN also decreased 62.0, 69.2, 62.0, 61.7, 62.4, and 52.4%, respectively. Groups I and S produced similar alterations in the studied parameters during GA. CONCLUSIONS: GA reduced all the HRV indices studied except for the nuHF.

PURPOSE: The purpose of this study was to investigate the effect on pain of distraction with an operating doll in preschool children(3-6 years old) during an IV catheter insertion. METHOD: The research design was a nonequivalent control group posttest design, and the participants were 22 children in the experimental group, and 23 children in the control group. The children were hospitalized for enteritis and pharyngitis in a university hospital. The subjective pain was measured using FACES Pain Rating Scale by self report, and the pain behavior responses were scored using Procedure Behavior Check List by observing a film of the entire procedure, and changes in pulse and oxygen saturation as the physiological pain responses were measured by pulse oximeter. Data were analyzed with the SPSS Win 10.0 program. RESULT: The degree of subjective pain, pain behavior responses, and changes in pulse during IV catheter insertion were significantly lower in the experimental group. But there was no significant difference in O2 saturation between the two groups. CONCLUSION: Distraction using an operating doll was effective in decreasing pain during inserting the IV catheter in preschool children.

PURPOSE: The purpose of this study was to investigate the effects on weight of premature infants when Yakson therapy was conducted by mothers and also to measure role confidence and role satisfaction of the mothers. METHOD: A non-equivalent control group non-synchronized design was used. The data were collected from January to July, 2005. Thirty preterm infants and mothers were assigned to either an experimental (15) or a control group (15). Yakson therapy consists of three phases: laying on of hands, caressing by hands, and laying on of hands again, each phase taking 5 minutes. Yakson therapy was provided to infants in the experimental group for 15-minutes 5 times a day for 15 days. Infant weight, mothers' role confidence and satisfaction with role were measured for both groups. RESULTS: Compared to the control group, weight gain of infants in the experimental group (t=2.05, p=.049) was significantly increased after 15 days. The experimental group also had significantly higher scores in mothers' role confidence (t=1.98, p=.038). CONCLUSION: The results suggest that Yakson therapy can be used to increase weight gain in preterm infants and improve the role confidence of mothers.

This study assessed the association between vitamin D sufficiency (serum 25(OH)D > or =30 ng/mL) and alcohol consumption using data from the Korea National Health and Nutrition Examination Survey conducted in 2009. The following characteristics were obtained in 7,010 Korean participants > or =19-years-of-age: serum 25(OH)D level, alcohol consumption (drinking frequency, drinking number of alcoholic beverages on a typical occasion, average daily-alcohol intake), and potential confounders (age, residence, housing status, occupation, total fat and lean mass, smoking, physical activity, history of liver diseases, liver function, and daily intake of energy, protein, and calcium). After adjusting for confounders, vitamin D sufficiency in men was significantly associated with drinking frequency, number of alcoholic drinks consumed, and average daily alcohol intake; odds ratio of 1.21-1.72, 2.17-3.04, and 2.27-3.09, respectively. Increase in the three alcohol drinking-related behaviors was also linearly associated with increase in serum 25(OH)D level in men. By comparison, there was no significant association between alcohol intake and serum 25(OH)D level in women. The positive association between vitamin D sufficiency and alcohol consumption was evident only in Korean men.

Whether the FTO polymorphisms interact with environmental factors has not yet been evaluated in associations with metabolic syndrome (MS) risk. The present study investigated the association of the FTO rs9939609 genotypes, body mass index (BMI), and lifestyle-related factors including smoking, alcohol drinking, physical activity, and diet with MS incidence. A population-based prospective cohort study comprised 3,504 male and female Koreans aged 40 to 69 years. At the beginning of the study, all individuals were free of MS and known cardiovascular disease. Incident cases of MS were identified by biennial health examinations during a follow-up period from April 17, 2003 to April 15, 2009. Pooled logistic regression analysis was applied to obtain relative odds (RO) of MS with its 95% confidence interval (CI). After controlling for potential MS risk factors, we observed no association between the rs9939609 genotypes and MS incidence. In analysis stratified by BMI, however, carriers with the FTO risk allele whose BMI is 29 kg/m2 or greater showed an approximately 6-fold higher RO (95% CI: 3.82 to 9.30) compared with non-carriers with BMI less than 25 kg/m2. In particular, the association between the rs9939609 variants and MS risk was significantly modified by high BMI (P-value for interaction < 0.05). Such significant interaction appeared in associations with central obesity and high blood pressure among the MS components. Because carriers of the FTO risk alleles who had BMI of 29 kg/m2 or greater are considered a high risk population, we suggest that they may need intensive weight loss regimens to prevent MS development.

Flavan-3-ols are a subclass of flavonoids found in a variety of foods including teas. The effects of flavan-3-ols on the risk of metabolic syndrome (MetS) have been investigated, generally focusing on tea catechins or individual flavan-3-ol rich foods, but there is little information on dietary flavan-3-ols intake and risk of MetS in population-based studies. In this cross-sectional study, we examined the association between dietary flavan-3-ols intake and the risk of MetS in Korean adults. Subjects comprised 1,827 men and 2,918 women aged 20-69 years whose data was included in the 2008 Korean National Health and Nutrition Examination Survey. This survey was conducted between January 2008 and December 2008. Total flavan-3-ols intakes were calculated from 24-hour dietary recalls using a flavonoids database. Thirty percent of the male subjects and 24% of the female subjects were reported as having MetS. In the female subjects, flavan3-ols intake was inversely associated with the risk of MetS after adjusting for potential confounders (5th vs. 1st quintile, OR = 0.64, 95% CI = 0.45-0.91, P for trend = 0.384). The main food source of flavan-3-ols was green tea followed by apples and grapes. Among MetS components, flavan3-ols intake was inversely associated with the risk of high blood pressure after adjusting for potential confounders (5th vs. 1st quintile, OR = 0.64, 95% CI = 0.45-0.90, P for trend = 0.005). No significant association between flavan-3-ols intake and risk of MetS was found in the male subjects. After stratified analysis by obesity (BMI > or = 25 or BMI < 25), however, flavan3-ols intake was inversely related to the risk of hypertension in non-obese men. These results suggest that dietary flavan-3-ols intake may have beneficial effects on MetS risk by reducing the risk of hypertension. The effects of flavan-3-ols intake dependent on obesity need further investigation.

Intradural disc herniation is a very rare condition, and multiple intradural disc herniations have not been reported to date. The latter may be confused with intradural extramedullary (IDEM) spinal tumors. Here, we report a case of multiple intradural disc herniations masquerading as multiple IDEM tumors and review the relevant literature. We retrospectively reviewed the patient's medical chart, reviewed the intraoperative microscopic findings, and reviewed of PubMed articles on intradural disc herniation. The masses considered to be IDEM tumors were confirmed to be multiple intradural disc herniations. A nonenhancing mass was found to have migrated along the intra-arachnoid space. Two enhancing masses could not migrate because of adhesion and showed peripheral neovascularization. We report an extremely rare case of multiple intradural lumbar disc herniations showing diverse enhancing patterns and masquerading as multiple IDEM tumors. In case of multiple enhancing IDEM masses suspected preoperatively, surgeons should consider the possibility of intradural disc herniation.

OBJECTIVE: A fibrin sealant is commonly applied after closure of an incidental or intended durotomy to reduce the complications associated with the leakage of cerebrospinal fluid. Routine usage might not be essential after closure of an intended durotomy, which has clear cut-margins. We investigated the efficacy of fibrin sealants for primary intradural spinal cord tumor surgery. METHODS: A retrospective review was performed for 231 consecutive surgically treated patients with primary intradural spinal cord tumors without extradural extension. Fibrin sealants were not used for 47 patients (group I: age, 51.57±16.75 years) and were applied to 184 patients (group II: age, 48.8±14.7 years). The surgical procedures were identical except for the use of a fibrin sealant after closure of the durotomy. The primary outcome was the occurrence of complications (wound problems, hematoma collection, infection, and neurological deterioration). The covariates were age, sex, body mass index, operation time, pre-/postoperative ambulation, number of laminectomies, and type of tumor. RESULTS: Schwannoma was the most common pathology (n=134), followed by meningioma (n=35) and ependymoma (n=31). Complications occurred in 13 patients (3 in group I and 10 in group II, p=0.73). The postoperative ambulation status (p<0.01; odds ratio, 28.8; 95% confidence interval, 6.9-120.0) and operation time (p=0.04; cutoff, 229 minutes; sensitivity, 62%; specificity, 72%) were significant factors, whereas the use of a fibrin glue was not (p=0.47). CONCLUSION: The use of a fibrin sealant might not be essential to reduce complications after surgery for primary spinal intradural tumor.
