BACKGROUND: Elderly patients often have postoperative psychiatric disorders compared with young patients. METHODS: This study was undertaken to compare the effects of general or regional anesthesia on postoperative psychiatric disorders in 31 elderly patients with elective orthopedic and urological surgery. Mini Mental States Examinations(MMSE) was done to find out postoperative delirium at preoperative, postoperative 6hours, 1st, 3rd, and 7th days. RESULTS: Mean changes in MMSE score after general anesthesia were significantly decreased compared with preoperative score and with in regional anesthesia at postoperative 6 hours and 1st day. Postoperative MMSE scores were decreased below 17 points in 17 patients among 22 patients in general anesthesia and 3 patients among 26 patients in regional anesthesia. Hospital admission duration were significantly prolonged in general anesthesia compare with regional anesthesia. CONCLUSIONS: The incidence of postoperative delirium is more common after general aneshtesia than after regional anesthesia. Therefore regional anesthesia is recommeded in elderly patients to decrease postoperative delirium.

In the modern practice of general anesthesia, endotracheal intubation is routinely used for controlled ventilation. To facilitating intubation, succinlycholine is the most valuable muscle relaxant. But succinylcholine has many untoward reactions such as elevation of intraocular pressure, increased plasma potassium, increased intragastric pressure, bradycardia and the development of postperative muscle pain, etc. Several attempts have study was intended to determine adequate doses of gallamine triethiodide for endotracheal intubation in patients to avoid the development of bradycardis. The authors measured the heart rate just beofre, immediately after and 5 minutes after intubation. The total number of patients in this study was 67, and the patients were divided into five groups: Group 1: consisting of 10 patients, receiving 1.5 mg/kg of gallamine triethiodide. Group 2: of 10 patients, receiving 2.0 mg/kg of gallamine. Group 3: of 22 patients, receiving 2.5 mg/kg of gallamine. Group 4: of 15 patients, receiving 3.0 mg/kg of gallamine. Group 5: of 10 patients, receiving 3.5 mg/kg of gallamine. The authors tried to choose the least difficult intubation after gallamine triethiodide, the amount administered and the patient's reaction to stimulation. The conclusions are summarized as follows: 1) The adequate dose of gallamine triethiodide for endotracheal intubation is 2.5mg/kg. 2) The duraion of action of gallamine triethiodide is dose dependent. 3) Increase of heart rate in each group is significant after gallamine triethiodide.

PURPOSE: To determine (1) the relationship between the cortical defects seen on 99 mTc-DMSA renal scans and age, and (2) the presence and degree of vesicoureteral reflux, and then to depict the risk factors for cortical defects in children with acute urinary tract infection (UTI). Furthermore, to assess the diagnostic value of VCUG in predicting a defect on 99 mTc-DMSA renal scans. MATERIALS AND METHODS: We studied 134 kidneys in 67 children aged 15 days-10 years (M:F=39:28) in whom symptomatic UTI was present. In all these children, both DMSA renal scans and voiding cystourethrography (VCUG) were performed. Scanning took place within 7 days of diagnosis and VCUG was performed after one month of diagnosis. Scintigraphic findings were graded according to the extent and number of cortical defects. We evaluated the relationships between the cortical defects seen on DMSA scans and age, and the grade of vesicoureteral reflux. The diagnostic value of VCUG in predicting cortical defects was analysed. Results: The prevalence of cortical defects was greater in patients older than two years (38/54, 70%) than in those aged less than two (38/80, 48%). The frequency of cortical defects was related to vesicoureteral reflux (p<0.05) and grade of reflux (p<0.05). As this latter increased, the extent of cortical defects also increased (p<0.05), and DMSA scans revealed the presence of these in 76 of the 134 kidneys (57%) with acute UTI. In 30 of these 76 (39.5%), VCUG demonstrated the presence of vesicoureteral reflex. On the other hand, vesi-coureteral reflex was found in 36 of the 134 kidneys (27%), and in 30 of these 36 (83%), cortical defects were noted. The sensitivity of VCUG in predicting cortical defect was 39.5%, while specificity was 89.7%. The positive predictive value for defects was 83.3%, and the negative predictive value was 53.1%. The relative risk of cortical defect in the presence of vesicoureteral reflux was 1.78. CONCLUSION: Renal cortical defects are significantly related to age and grade of vesicoureteral reflux. Risk factors for developing cortical defects were older age (> or =2yrs) at the time of acute UTI, and high grade of vesicoureteral reflux. The specificity of VCUG in predicting cortical defects is relatively high but the sensitivitiy is low, and a significant proportion of cortical defects therefore occurred in the absence of vesicoureteral reflux.

PURPOSE: To investigate the different types of anatomical connection between the lacrimal sac and the canaliculi using digital subtraction dacryocystography (DCG) in Koreans. METHODS: The authors of the present study performed digital subtraction DCG in Korean patients who presented with epiphora from January 2010 until December 2010. The 248 patients (496 eyes) who achieved a satisfactory DCG image were classified as follows: 1) type I: visible common canaliculus (CC), 2) type II: no visible CC and the canaliculi entering the sac at the point where they meet on the sac wall (common opening), 3) type III: no visible CC and common opening, and each canaliculus entering the sac from different points. RESULTS: Out of a total of 496 eyes, CC was observed in 449 eyes (type I: 90.5%). In 41 eyes (8.3%), the CC was absent (type II), but the upper and lower canaliculi joined at the wall of the lacrimal sac. In 6 eyes (1.2%), the upper and lower canaliculi entered the sac separately (type III). Eighteen patients (7.3%) showed different types of lacrimal drainage system between the 2 eyes. CONCLUSIONS: The CC may not exist in all patients, and the type of anatomical connection between the lacrimal sac and the canaliculi may be different between the eyes in the same individuals. Although such patients comprise a minority, anatomical knowledge of the lacrimal drainage system could be helpful to assess and manage patients with lacrimal drainage disorder.

BACKGROUND: In spite of the successful reperfusion therapy, coronary blood flow in infarcted myocardium was known to decrease for a long time. Abciximab is known to inhibit the final pathway of platelet aggregation and maintenance the large vessel patency. But abciximab may have another important effect beyond the these effect. TIMI frame count method is simple, reproducible, objective and quantitative index of coronary flow. We tried to define the effect of abciximab that used with primary angioplasty on the coronary blood flow using TIMI frame count methods. METHODS: We consecutively studied 30 patients who admitted for acute myocardial infarction without cardiogenic shock from September 1997 to August 1999. We analyzed the changes of corrected TIMI frame count(CTFC) between the baseline(immediate after the angioplasty) and follow-up(post-op 7th day) coronary angiogram and compared the results between the group of primary angioplasty with abciximab(abciximab group, n=1) and the group of primary angioplasty without abciximab(non-abciximab group, n=9). RESULTS: There were no differences between abciximab group and non-abciximab group in baseline characteristics, treatment modalities and angiographic results. According to the results of the comparison of deltaCTFC, changing rate of CTFC, deltavelocity and changing rate of velocity, there were significant improvement of the coronary blood flow in infarct related artery in the abciximab group than non-abciximab group. But there were no differences in the changes of coronary blood flow in non-infarct related artery between two groups. The frequency of major adverse coronary events during follow up periods(mean 6 months) were similar(9.1% and 5.2% each other, p>0.05). CONCLUSIONS: Abciximab used with primary angioplasty in acute myocardial infarction improved the coronary blood flow significantly in infarcted myocardium. This finding may be related that abciximab enhance the perfusion and function of microvasculature in infarcted myocardium.

The study was performed to see the effects of coenzyme Q₁₀ (CoQ₁₀) on blood biochemical components and hepatic antioxidant system in rats exposed to lipopolysaccharide (LPS)-induced toxicity. A total of 24 rats were allocated to four groups: control (CON), 100 mg/kg BW of LPS (LPS), 100 mg of CoQ₁₀/kg BW with LPS (LCQI) and 300 mg of CoQ₁₀/kg BW with LPS (LCQII). The LPS and LCQI groups showed a significant (P<0.05) increase in the relative spleen weight compared with the CON group without affecting body and liver weights. The blood alanine aminotransferase (ALT) level in the LPS group was significantly (P<0.05) greater than that in the CON group, while supplementation with 100 or 300 mg CoQ₁₀ to rats injected with LPS normalized the ALT level in the CON group. In antioxidant systems, the LPS group showed a significantly (P<0.05) higher mRNA and activity of superoxide dismutase (SOD) than the CON group. The supplementation with CoQ₁₀ to the LPS-treated group normalized the level of SOD, which was comparable to the level of the CON group. Both the mRNA expression and activity of glutathione peroxidase in the LCQI and LCQII groups were higher (P<0.05) than that of the LPS group. However, administration of LPS or CoQ₁₀ unaffected the level of catalase and total antioxidant power. The level of lipid peroxidation in the LCQII group was lower (P<0.05) than that in the LPS group. In conclusion, CoQ₁₀ exerted its favorable effect against liver damage by modulation of antioxidant enzymes in LPS treated rats.

OBJECTIVES: Childhood depressive disorder one of the most prevalent chronic health conditions affecting school aged children. The objective of this study was to examine the prevalence and epidemiological characteristics of childhood depressive disorder in Korea. METHODS: In this study, a survey was conducted of elementary school children in the Cheonan area from September 2009 to August 2010. A total of 12,084 children were included in the analyses. The primary measure of depression was the 27-item Kovacs' Children's Depression Inventory (CDI), the Korean Dupaul attention-deficit hyperactivity disorder Rating Scales (K-ARS), Autism Spectrum Screening Questionnaire (ASSQ) and Restless Legs Syndrome Questionnaire (RLSQ) were also administered. RESULTS: The prevalence rate of childhood depressive disorder was 3.07%. The mean age was 9.21+/-1.81 years for the control group (5,969 male, 6,054 female) and 9.91+/-1.83 years for the depression group (CDI score> or =22 ; 159 male, 210 female). Age, height, weight, and economic status were similar for the two groups. However, there were statistically significant differences in the distribution of sex. The distribution of school grade also differed between the two groups. Scores for CDI, K-ARS, and ASSQ in the depressive group were higher than those of the control group. CONCLUSIONS: This is the first large-scale population-based study to report on the prevalence of childhood depressive disorder in South Korea. Increased rates of childhood depressive disorder, as reported by primary caretakers, might reflect the increasing negative impact of environmental risk factors on neurobehavioral health. Longitudinal study of the prevalence of childhood depressive disorder should be considered for further evaluation.

PURPOSE: Fractional exhaled nitric oxide (FeNO) is useful for the diagnosis of allergic rhinitis (AR) as well as bronchial asthma (BA). However, FeNO may differ according to race, age, and other determinants. There have been few studies about FeNO in Korean children with AR. The aims of this study were to evaluate the value of FeNO in AR and to compare FeNO, and determinants of FeNO levels between AR, BA, and combined AR and BA. METHODS: This study included 647 children aged 5 to 17. The children were classified into 5 groups after performing the skin test, FeNO measurement, the pulmonary function test, and the methacholine challenge test: those with nonallergic rhinitis (NAR), those with AR, those with BA, and those with combined AR and BA, and healthy controls,. RESULTS: The values of FEV1 (forced expiratory volume in one second) %predicted were 94.4%+/-12.6%, 93.8%+/-20.7%, 90.0%+/-17.4% in AR, BA, and combined AR and BA, respectively. The values of FeNO in AR (32.3+/-25.0 ppb), BA (31.1+/-20.5 ppb), and combined AR and BA (34.5+/-30.4 ppb) were significantly higher compared to those of NAR (16.8+/-13.5 ppb) and controls (15.9+/-12.5 ppb). There was no significant difference in FeNO among AR, BA, and combined AR and BA. FeNO was significantly higher in patients with > or =4 positive results (36.6+/-29.2 ppb) than in those with <4 positive skin test results (27.6+/-20.7 ppb). When the receiver operating characteristic curve analysis for prediction of AR showed 0.756 of area under the curve, the cutoff level of FeNO was 16 ppb. CONCLUSION: In this study, children with AR had increased levels of FeNO. It is suggested that AR may have eosinophilic bronchial inflammation without BHR or clinical asthma.
