Objectives:
:This study aimed to investigate the prevalence of internet game addiction and its association with environmental characteristics such as parent supervision, gaming hour (time spent on gaming) and attention-deficit hyperactivity disorder (ADHD) symptoms among middle school students.
Methods:
:A total of 596 (416 males and 180 females) first grade middle-school students in Gwang-ju metropolitan city were included in this study. Subjects were asked to complete a self-reported questionnaire, including measures of the Internet Gaming Use-Elicited Symptom Screen (IGUESS), Attention deficit hyperactivity disorder (ADHD) symptom, environmental factor such as parent supervision, and game related factor like game hours. Internet Game addiction and non-addiction group were defined using IGUESS score of 10 as a cut-off. The data were analyzed using hierarchical regression analyses.
Results:
:Internet Game addiction group was fifty-two subjects (8.7%). Male students were significantly higher than female students (OR 25.01). IGUESS score was statistically negatively correlated with parent attachment and parent supervision, while IGUESS score was positively correlated with time spent on gaming per day, the longest time spent on gaming per day and violent game and ADHD score. Among variables, IGUESS score showed the highest correlation with the longest time spent on gaming per day (r=0.373, p<0.01). Using hierarchical regression analyses, the longest time spent on gaming per day was also the highest predicting factor affecting internet game addiction among variables.
Conclusion
:Our findings indicate that parent supervision, parent attachment and game related characteristics such as gaming per day, the longest time spent on gaming per day and violent game and ADHD were associated with internet game addiction.

PURPOSE: This study aimed to identify the neural basis of executive function (EF) in amnestic mild cognitive impairment (aMCI) according to beta-amyloid (Aβ) positivity. Furthermore, we explored if the identified brain areas could serve as predictors for clinical progression. MATERIALS AND METHODS: We included individuals with aMCI using data from [¹⁸F]-florbetapir-positron emission tomography (PET), fluorodeoxyglucose-PET, and EF scores, as well as follow-up clinical severity scores at 1 and 5 years from baseline from the Alzheimer's Disease Neuroimaging Initiative database. The correlations between EF score and regional cerebral glucose metabolism (rCMglc) were analyzed separately for aMCI with low Aβ burden (aMCI Aβ−, n=230) and aMCI with high Aβ burden (aMCI Aβ+, n=268). Multiple linear regression analysis was conducted to investigate the associations between rCMglc and clinical progression. RESULTS: Longitudinal courses differed between aMCI Aβ− and aMCI Aβ+ groups. On average, aMCI Aβ− subjects maintained their level of clinical severity, whereas aMCI Aβ+ subjects showed progression. EF impairment in aMCI Aβ− was related to the anterior cingulate cortex (ACC), whereas that in aMCI Aβ+ was related to Alzheimer's Disease-vulnerable brain regions. ACC and the posterior cingulate cortex were associated with clinical progression in aMCI Aβ− and aMCI Aβ+, respectively. CONCLUSION: Our findings suggest that although MCI subjects showed similar behavioral phenotypes at the time of diagnosis, EF and further progression were associated with different brain regions according to Aβ burden. Clarification of the etiologies and nature of EF impairment in aMCI are critical for disease prognosis and management.

This study aimed to investigate the independent and interactive influences of apolipoprotein E (APOE) epsilon4 and beta-amyloid (Abeta) on multiple cognitive domains in a large group of cognitively normal (CN) individuals and patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD). Participants were included if clinical and cognitive assessments, amyloid imaging, and APOE genotype were all available from the Alzheimer's Disease Neuroimaging Initiative database (CN = 324, MCI = 502, AD = 182). Individuals with one or two copies of epsilon4 were designated as APOE epsilon4 carriers (epsilon4+); individuals with no epsilon4 were designated as APOE epsilon4 non-carriers (epsilon4-). Based on mean florbetapir standard uptake value ratios, participants were classified as Abeta burden-positive (Abeta+) or Abeta burden-negative (Abeta-). In MCI, APOE epsilon4 effects were predominantly observed on frontal executive function, with epsilon4+ participants exhibiting poorer performances; Abeta positivity had no influence on this effect. Abeta effects were observed on global cognition, memory, and visuospatial ability, with Abeta+ participants exhibiting poorer performances. Measures of frontal executive function were not influenced by Abeta. Interactive effects of APOE epsilon4+ and Abeta were observed on global cognition and verbal recognition memory. Abeta, not APOE epsilon4+, influenced clinical severity and functional status. The influences of APOE epsilon4+ and Abeta on cognitive function were minimal in CN and AD. In conclusion, we provide further evidence of both independent and interactive influences of APOE epsilon4+ and Abeta on cognitive function in MCI, with APOE epsilon4+ and Abeta showing dissociable effects on executive and non-executive functions, respectively.

PURPOSE: To evaluate the efficacy and safety of once-daily ciclesonide in comparison to both levocetirizine alone, and a ciclesonide/levocetirizine combination in patients with seasonal allergic rhinitis (SAR) and perennial allergic rhinitis (PAR). METHODS: Subjects exhibiting moderate to severe allergic rhinitis for longer than 1 year were randomized in an open-label, 3-arm, parallel group, multicenter study. Subjects received 200 microg ciclesonide, 5 mg levocetirizine, or a combination of both. Changes from baseline until the end-of-study visit (2 weeks following) were evaluated by reflective total nasal symptom scores (rTNSSs), reflective total ocular symptom scores (rTOSSs), physician-assessed overall nasal signs and symptoms severity (PANS), and rhinoconjunctivitis quality-of-life questionnaires (RQLQ). RESULTS: Significant improvements in rTNSS, PANS, and RQLQ in the ciclesonide monotherapy group were observed in comparison to the levocetirizine alone group. Three individual symptoms of rTNSS, including runny nose, nasal itching, and congestion, were improved in the ciclesonide-treated group. rTOSS scores for ciclesonide monotherapy improved from baseline, but no superiority over levocetirizine was shown. The absolute score and changes in rTNSS and PANS were positively correlated. Ciclesonide spray was more effective than levocetirizine in reducing nasal symptoms in both SAR and PAR patients. Ciclesonide and levocetrizine were well tolerated alone and in combination. CONCLUSIONS: Our results provide support for an AR and its Impact on Asthma (ARIA) recommendation stipulating that ciclesonide is superior to levocetirizine for the treatment of AR, with tolerable safety. Addition of levocetirizine to ciclesonide did not give further clinical benefit over monotherapy.

A 16-year-old woman was referred to us for depression and persistent suicidal and homicidal ideation. From 2010, the patient visited a neurologist due to recurrent grand mal epilepsy, auditory and visual hallucinations, episodic memory loss, and persistent depression. Upon admission, it was revealed through clinical history taking that she had suffered from chronic bullying from same-sex peers and sexual abuse, twice, from an adult male in the neighborhood when she was 10 years old. A brain magnetic resonance imaging study showed left mesial hippocampal sclerosis. The patient exhibited improvement of her psychiatric symptoms after treatment with a combination of fluoxetine (30 mg) and aripiprazole (10 mg). Children and adolescents with epilepsy experience conflicts in the family, challenges at school, stigma, and psychosocial limitations or deprivations due to their comorbid psychiatric symptoms and hence, psychiatric evaluation and early intervention is important when treating these patients.

BACKGROUND: Ferulic acid (FA) is a naturally occurring nutritional compound. Although it has been shown to have antihypertensive effects, its effects on vascular function have not been intensively established. The aim of this study was to assess the vasoreactivity of FA in chronic two-kidney, one-clip (2K1C) renal hypertensive rats. METHODS: Hypertension was induced in 2K1C rats by clipping the left renal artery and age-matched rats that received a sham treatment served as a control. Thoracic aortas were mounted in tissue baths to measure isometric tension. The effects of FA on vasodilatory responses were evaluated based on contractile responses induced by phenylephrine in the aortic rings obtained from both 2K1C and sham rats. Basal nitric oxide (NO) bioavailability in the aorta was determined by the contractile response induced by NO synthase inhibitor NG-nitro-L-arginine methyl ester (L-NAME). RESULTS: FA induced concentration-dependent relaxation responses which were greater in 2K1C hypertensive rats than in sham-clipped control rats. This relaxation induced by FA was partially blocked by the removal of endothelium or by pretreating with L-NAME. L-NAME-induced contractile responses were augmented by FA in 2K1C rats, while no significant differences were noted in sham rats. FA improved acetylcholine-induced endothelium-dependent vasodilation in 2K1C rats, but not in sham rats. The simultaneous addition of hydroxyhydroquinone significantly inhibited the increase in acetylcholine-induced vasodilation by FA. CONCLUSION: These results suggest that FA restores endothelial function by altering the bioavailability of NO in 2K1C hypertensive rats. The results explain, in part, the mechanism underlying the vascular effects of FA in chronic renal hypertension.

OBJECTIVES: We attempted to compartmentalize the periaqueductal gray (PAG) of the rabbit in terms of the different distribution patterns between NADPH-diaphorase (NADPHd)- and calbindin D28K (CB)-positive neurons. METHODS: Immunohistochemistry and immunofluorescent labelling for CB and histochemistry for NADPHd were carried out on coronally-sectioned midbrain slices of the rabbit. RESULTS: NADPHd-positive neurons were selectively localized in the dorsolateral (DL), the middle one-third of the lateral (L), the dorsal half of the ventrolateral (VLd) PAG, and the supraoculomotor cap nucleus (Su3C). Clusters of CB-immunoreactive perikarya marked the dorsal half of DL (DLd), Su3C, the ventral one-third of L, and the ventral half of the ventrolateral (VLv) PAG. Double labelling for NADPHd and CB revealed that two markers labelled different neuronal groups in DLd and Su3C subdivisions. CONCLUSION: The present data suggest that NADPHd and CB can be regarded as reliable neurochemical markers to reveal the longitudinally-columnar organization within the PAG and to subdivide each columnar area.

BACKGROUND: Soft tissue defects of the posterior heel of the foot present difficult reconstructive problems. This paper reports the authors' early experience of five patients treated with a lateral calcaneal artery adipofascial flap. METHODS: Between 2003 and 2007, five patients (3 males and 2 females) with soft-tissue defects over the posterior heel underwent a reconstruction using a lateral calcaneal artery adipofascial flap and a full-thickness skin graft. The flap sizes ranged from 3.5 x 2.5 cm to 5.5 x 4.0 cm. RESULTS: All five flaps survived completely with no subsequent breakdown of the grafted skin, even after regularly wearing normal shoes. The adipofascial flap donor sites were closed primarily in all patients. CONCLUSIONS: Lateral calcaneal artery adipofascial flaps should be included in the surgical armamentarium to cover difficult wounds of the posterior heel of the foot. These flaps do not require the sacrifice of a major artery to the leg or foot, they are relatively thin with minimal morbidity at the donor site, and leave a simple linear scar over the lateral aspect of the foot.

BACKGROUND: Malignant pleural effusion is a common condition in neoplastic patients and palliative therapy is the usual treatment. Talc has been generally accepted to be the most effective sclerosant for chemical pleurodesis, but the optimal route of administration remains controversy. We compared the results of video-assisted thoracoscopic talc poudrage (VTP) with administering a bedside talc slurry through a chest tube (BTS) for the treatment of malignant pleural effusion. MATERIAL AND METHOD: From December 2004 to May 2006, 20 patients with malignant pleural effusion underwent chemical pleurodesis via VTP (group A, n=10), and BTS (group B, n=10). RESULT:The durations of chest tube placement after the procedure were 7.0+/-4.0 days (group A) and 6.7+/-3.6 days (group B). The hospital stays were 24.3+/-9.4 days (group A) and 30.7+/-21.5 days (group B), respectively. The symptoms of dyspnea were much more improved in group A (p-value=0.014) after discharge (mean f/u group A=8.5+/-2.2 months, group B 8.0+/-7.4 months). The collapsed portions of lung were better expanded in group A than in group B (p-value= 0.011). CONCLUSION: We recommend VTP for the selected patients with malignant pleural effusion because of the advantages of dissecting the fibrous peel to relieve the atelectasis and dyspnea, and excising the pleura for diagnosis with direct viewing of the lesion.

OBJECTIVE: To evaluate the association of level of CA-125 and severity of dysmenorrhea with lesion depth in adenomyosis. METHODS: Sixty-eight women who had undergone hysterectomy and were found to have pure adenomyosis on histopathologic examination were reviewed retrospectively. Specimens were stratified according to the degree of adenomyosis penetration into 4 groups: group A consisted of specimens with adenomyosis penetration into myometrium of up to 25%; group B, 26-50%; group C, 51-75%, and group D, >75%. All women were submitted to serum determination of CA-125. Severity of dysmenorrhea was assessed by means of a modification of 10-point verbal rating scale. RESULTS: Each group was not correlated with severity of dysmenorrhea (p=0.7394 Fisher's exact test). The means of serum CA-125 levels was increased corresponding to depth of adenomyosis (p=0.0441 ANOVA test). CONCLUSION: In this study, serum CA-125 level is associated with the depth lesion and severity of dysmenorrhea is not. Therefore, the level of serum CA-125 might be useful indicator in management of adenomyosis before surgery.
