Cirrhosis with portal hypertension is a common disease which has a significant impact on the quality of patients' life. Esophagogastric devascularization (EGDV) has been demonstrated to be an effective method to treat portal hypertension, however certain complications are associated with it. The purpose of this study was to evaluate the effectiveness and clinical outcome of the selective EGDV (sEGDV) for the treatment of portal hypertension. The study was conducted prospectively from Jan. 1 2011 to Dec. 31, 2012, and 180 patients were randomized to the sEGDV group (n=90) or the non-sEGDV (n-sEGDV) group (n=90). Patients' demographics, preoperative lab test results and operative details were comparable between the two groups. Postoperative and short-term complications were analyzed in two groups. There was statistically significant difference (P<0.01) in the PVF reduction between the two groups. Post-operative complications showed no statistically significant difference between the two groups in the incidence of bleeding, ascites, acute portal vein thrombosis, fever and hepatic encephalopathy. Mortality between two groups was comparable. The incidence of splenic fossa effusion after the surgery was lower in sEGDV group than in n-sEGDV group. There were no significant differences in the short-term follow-up data such as esophageal varices and portal hypertensive gastropathy (P>0.05). It is suggested that sEGDV is a safe, simple and effective surgical procedure. It has both the advantages of the shunt and devascularization because it preserves body's voluntary diversion. With the advantage of low incidence of postoperative complications, it is an ideal surgical approach for the treatment of portal hypertension.

OBJECTIVE: Due to longer life spans, patients newly diagnosed with unruptured intracranial aneurysms (UIAs) are increasing in number. This study aimed to evaluate how management of UIAs in patients age 65 years and older affects the clinical outcomes and post-procedural morbidity rates in these patients. METHODS: We retrospectively reviewed 109 patients harboring 136 aneurysms across 12 years, between 1997 and 2009, at our institute. We obtained the following data from all patients : age, sex, location and size of the aneurysm(s), presence of symptoms, risk factors for stroke, treatment modality, and postoperative 1-year morbidity and mortality. We classified these patients into three groups : Group A (surgical clipping), Group B (coil embolization), and Group C (observation only). RESULTS: Among the 109 patients, 56 (51.4%) underwent clipping treatment, 25 (23%) patients were treated with coiling, and 28 observation only. The overall morbidity and mortality rates were 2.46% and 0%, respectively. The morbidity rate was 1.78% for clipping and 4% for coiling. Factors such as hypertension, diabetes mellitus, hypercholesterolemia, smoking, and family history of stroke were correlated with unfavorable outcomes. Two in the observation group refused follow-up and died of intracranial ruptured aneurysms. The observation group had a 7% mortality rate. CONCLUSION: Our results show acceptable favorable outcome of treatment-related morbidity comparing with the natural history of unruptured cerebral aneurysm. Surgical clipping did not lead to inferior outcomes in our study, although coil embolization is generally more popular for treating elderly patients. In the treatment of patients more than 65 years old, age is not the limiting factor.

OBJECTIVES: The purpose of the study was to examine the relationships between temperament and character dimensions and family environments, and to investigate the influences of those factors on the antisocial personality traits in delinquent adolescents. METHODS: The subjects consisted of 160 male adolescents detained at the public prosecutor's office on the suspicion of crimes. To assess personality dimensions and family environmental factors, the Temperament and Character Inventory(TCI) and the Family Environment Scale(FES) were completed. Antisocial personality traits were assessed by the number of antisocial personality disorder symptoms of the Personality Disorder Questionnaire-Revised. RESULTS: Most of the TCI dimensions except Reward Dependence(RD) were highly correlated with the subscales of FES. Among temperament dimensions, Novelty Seeking(NS) and Persistence(P) were significantly affected by Organization, and Harm Avoidance(HA) was influenced by Expressiveness of FES. Self-Directednss(SD) was best predicted by Organization and Achievement-Orientation. While the Independence had significant effect on Cooperativeness, Expressiveness and Achievement-Orientation best predicted the level of Self-Transcendence(ST). On factor analysis, NS, HA, SD and ST were allocated to the same factors with subscales of FES. The level of antisocial personality trait was best predicted by NS, P and SD scores of TCI, and conflict subscale scores of FES. CONCLUSION: The findings of this study suggest that not only the character dimensions but also the temperament dimensions have close relationships with family environmental factors, and that the antisocial personality traits of delinquent adolescents may developed by the interaction between temperament/character dimensions and family environments.

This study was aimed to investigate the effect of baicalin on proliferation and apoptosis of HL-60 cells and its mechanism. Cell proliferation was assayed by using Cell Counting Kit-8. The morphological changes of HL-60 cells were examined by light microscopy and nucleolus morphological changes were observed by fluorescent microscopy after Hoechst 33342 staining. The early cell apoptosis was detected by using flow cytometry with Annexin V-FITC/PI double staining. The expression of caspase-3, caspase-9, Bcl-2 and Bax mRNA was detected by RT-PCR and Western blot assay was carried out to examine Bax, Bcl-2, caspase-8 and cleaved caspase-3 expression. The results showed that Baicalin inhibited the proliferation of HL-60 cells in a time- and concentration-dependent manner. HL-60 cells exhibited typical morphological features (for example, cell shrinkage, membrane blebbing and formation of apoptotic bodies). Cell apoptosis in early stage could be detected, the expression of caspase-3, caspase-9 and Bax mRNA was obviously up-regulated, while the Bcl-2 expression down-regulated, and accordingly Bcl-2/Bax ratio decreased. Such results were consistent with the expression of these proteins. In addition, the expression of cleaved caspase-8 protein was induced significantly after treated with baicalin. It is concluded that baicalin can significantly inhibit the proliferation of HL-60 cells and induce the apoptosis of HL-60 cells, which may occur through decreasing Bcl-2/Bax ratio by intrinsic pathway and through extrinsic pathway. It suggests that baicalin may be a promising drug for the therapy of acute myeloid leukemia.

OBJECTIVE: This study examined the differences in psychiatric comorbidities and behavioral aspects in accordance with the severity of Internet addiction in male adolescents. METHODS: One hundred and twenty-five adolescents from four middle and high schools in Seoul were enrolled in this study. The subjects were divided into non-addict, abuse, and dependence groups according to a diagnostic interview by psychiatrists. The psychiatric comorbidities and behavioral aspects of subjects were evaluated through psychiatric clinical interviews based on the Diagnostic and Statistical Manual of Mental Disorders (4th edition), the Children's Depression Inventory, the State-Trait Anxiety Inventory, the Internet Addiction Test, and a self-reported questionnaire about behavioral aspects. RESULTS: The psychiatric comorbidity distributions were significantly different in the abuse and dependence groups, particularly in terms of attention-deficit hyperactivity disorder and mood disorder items. The Children's Depression Inventory, the State-Trait Anxiety Inventory, and the Internet Addiction Test scores were also significantly different among the three groups. There were significant differences in 10 of the 20 items of the Internet Addiction Test between the non-addict, abuse, and dependence groups. There were significant differences in seven items between the non-addict and abuse groups, but no differences between subjects in the abuse and dependence groups. Significant differences were observed in three items between the abuse and dependence groups, but there were no significant differences between the non-addict and abuse groups. In terms of behavioral aspects, scores for abusive, sexual, and decreased social interest behaviors were highest in the dependence group, and lowest in the non-addict group. However, the behavioral aspects of decreased interpersonal relationships did not show this difference between groups. CONCLUSION: This study suggests that there are differences in psychiatric comorbidities and behavioral aspects between adolescent males with characteristics of Internet abuse and Internet dependence.

PURPOSE: This retrospective study was conducted to estimate the effects of climate factors and air pollution on asthma exacerbations using a case-crossover analysis. METHODS: Patients who visited the emergency department (ED) of 2 university hospitals in Chuncheon for asthma exacerbations from January 1, 2006, to December 31, 2011, were enrolled. Daily average data for meteorological factors (temperature, daily temperature range, relative humidity, wind speed, atmospheric pressure, presence of rain, solar irradiation, and presence of fog) and the daily average levels of gaseous air pollutants (SO2, NO2, O3, CO, and PM10) were obtained. A case-crossover analysis was performed using variables about the weather and air pollution at 1-week intervals between cases and controls before and after ED visits. RESULTS: There were 660 ED visits by 583 patients with asthma exacerbations. Low relative humidity (lag 1 and 2) and high wind speed (lag 1, 2, and 3) were associated with ED visits for asthma. Fog (lag 2) showed protective effects against asthma exacerbations in Chuncheon (risk increase: -29.4% [95% CI=-46.3% to -7.2%], P=0.013). These relationships were stronger in patients ≤19 years old than in those >60 years old. High levels of ambient CO (lag 1, 2, and 3) and NO2 (lag 2 and 3) were associated with decreased ED visits for asthma. However, there were no significant relationships among levels of ambient CO or NO2 and asthma exacerbations after adjusting for wind speed and relative humidity. CONCLUSIONS: High wind speed and low humidity were associated with an increased risk of asthma ED visits. Fog was associated with a decreased risk of asthma ED visits after controlling for seasonal variations in weather and air pollution.

OBJECTIVE: Direct surgical clipping of paraclinoid aneurysms is challenging due to nearby anatomic structures. However, as endovascular techniques advance, endovascular coil embolizations for paraclinoid aneurysms are more frequently performed. We reviewed our experience with endovascular coil embolization of paraclinoid aneurysms to evaluate its safety and efficacy. METHODS: From 2005 to 2011, 78 patients underwent endovascular procedures with detachable coils for 86 paraclinoid aneurysms at our institute. A retrospective review of the medical records was performed. RESULTS: Seventy-eight patients with 86 paraclinoid aneurysms were evaluated. Thirteen patients (16.7%) were men and 65 (83.3%) were women. Patient age ranged from 23 to 78 years (mean age, 48 years). Five patients (6.4%) presented with subarachnoid hemorrhage (SAH) with decreased consciousness and visual field defects. In the 86 treated aneurysms, the immediate post procedural angiogram demonstrated complete occlusion in 73 aneurysms (84.9%), near-complete occlusion in eight aneurysms (9.3%) and partial occlusion in five aneurysms (5.8%). We obtained angiographic follow-up in 46 cases. Minor recanalization occurred in two cases and major recanalization occurred in one case. One thromboembolic complication and one blurred vision occurred among the 78 patients. CONCLUSION: Despite difficulties with surgical approaches for paraclinoid aneurysms, these lesions can be successfully managed by endovascular treatment. Favorable outcomes with a low morbidity suggest endovascular techniques as alternatives to microsurgical therapy for treating paraclinoid aneurysms.

PURPOSE: The operative risk and natural history rupture risk for the treatment of unruptured intracranial aneurysms (UIAs) should be evaluated. The purpose of this study was to report our experience with treating UIAs and to outline clinical risk factors associated with procedure-related major neurological complications. MATERIALS AND METHODS: We treated 1158 UIAs in 998 patients over the last 14 years. All patients underwent operation performed by a single microvascular surgeon and two interventionists at a single institution. Patient factors, aneurysm factors, and clinical outcomes were analyzed in relation to procedure-related complications. RESULTS: The total complication rate was 22 (2.2%) out of 998 patients. Among them, complications developed in 14 (2.3%) out of 612 patients who underwent microsurgery and in 8 (2.1%) out of 386 patients who underwent endovascular procedures. One patient died due to intraoperative rupture during an endovascular procedure. The procedure-related complication was highly correlated with age (p=0.004), hypertension (p=0.002), and history of ischemic stroke (p<0.001) in univariate analysis. The multivariate analysis revealed previous history of ischemic stroke (p=0.001) to be strongly correlated with procedure-related complications. CONCLUSION: A history of ischemic stroke was strongly correlated with procedure-related major neurological complications when treating UIAs. Accordingly, patients with UIAs who have a previous history of ischemic stroke might be at risk of procedure-related major neurological complications.

OBJECTIVE: Continuous performance tests (CPTs) are frequently used in clinical practice to assess the attentiveness of ADHD children. Although most CPTs do not categorize T scores by intelligence, there is great diversity of opinion regarding the interrelation between intelligence and CPT performance. This study aimed to determine if ADHD children with superior IQs would perform better than ADHD children with average IQs. Additionally, we aimed to examine the need for CPTs' to categorize according to IQ. METHODS: Participants were 326 outpatients, aged 5-15 years, diagnosed with ADHD. All participants completed the Wechsler Intelligence Scale for Children-Revised and a CPT. After excluding those who meet exclusion criteria, we had 266 patients for our analysis. RESULTS: The "Highly Intelligent Group" (HIG), patients with IQs 120 and above, performed superiorly to the "Normally Intelligent Group" (NIG) patients, with IQs between 70 and 120, with regard to omission and commission errors on the visual-auditory CPT, even after controlling for age and gender. The HIG had higher ratios of subjects with T scores <65 on the visual and auditory CPT variables than the NIG did. CONCLUSION: The results of this study suggest this CPT is not sensitive for discerning ADHD in children with superior IQs; thus, there is a need to standardize the variables based on IQ, as well as on age and gender. Moreover, clinicians need to pay attention to the effect of IQ in interpreting CPT scores; that is, a "normal" score does not rule out a diagnosis of ADHD.
