OBJECTIVE: Suicide is a leading cause of death in college age students. Identification of the associated risk factors has important implications for how to prevent and respond to this population; however, few studies have been performed on this topic in this age group. The purpose of this study was to evaluate the prevalence and risk factors associated with suicide ideation and attempts in college students. METHODS: Three hundred sixty-eight college students participated in this cross-sectional observational study. The recent (over two weeks) suicide ideation and lifetime suicide attempts were defined according to Moscicki's suicide behavior index. Sociodemographic variables were assessed and psychopathology measured using the Beck Depression Inventory, the Bipolar Spectrum Diagnostic Scale and the Alcohol Use Disorders Identification Test. A hierarchical multiple logistic regression analysis was used to identify the significant risk factors related to suicide ideation and attempts. RESULTS: The two-week prevalence of suicidal ideation was 9.8%, and the lifetime prevalence of suicide attempts was 3.3%. The univariate analysis showed that students who had more severe depression (p<0.001), a higher probability for bipolar disorder (p<0.001) and decrement of academic achievement (p<0.005) were more likely to have suicide ideation. Those with factors such as severe depression (p<0.05), a higher probability of bipolar disorder (p<0.001), a low socioeconomic status (p<0.001), who lived alone (p<0.01), and were female (p<0.05) had a higher risk for suicide attempts. The most important predictors of suicide ideation, by the logistic regression analysis, were depression, probability for bipolar disorder and academic achievement, and the risks identified for suicide attempts were socioeconomic status and probability of bipolar disorder. CONCLUSION: Suicide ideation and attempts were common in college students. The results of this study suggest that early identification and management of mood disorders and other sociodemographic risk factors may have implications for intervention and prevention.

PURPOSE: To evaluate the CT and MRI findings of neurosyphilis. MATERIALS AND METHODS: We retrospectivelyreviewed the CT and MR imaging findings in five patients with intracranial neurosyphilis confirmed by CSF, VDRL,TPHA, and clinical follow-up. MR imaging was performed in all five cases, and CT in two. RESULTS: The MRI and CTfindings of intracranial neurosyphilis included infarction (n=3), focal inflammation (n=1) and encephalopathy(n=1). There was a total of ten infaretions : three of the basal ganglia, two each of the frontal lobe, watershedzone, and cerebellum, and one of the occipital lobe. Intaretion was most common in MCA territory (n=9; 50%),followed by the watershed zone (16.6%), posterior cerebral artery territory (16.6%), and posterior inferiorcerebellar artery territory (11.1%), The size of the lesion varied from 1cm to larger than one lobe. One patientshowed diffuse high signal intensity in the left temporal lobe, but on follow-up MRI, this had resolved. CONCLUSION: The most common finding of neurosyphilis, as seen on MRI and CT, was infarction in middle cerebralarterial territory.

OBJECTIVE: The objective of this study was to identify patterns of brain activation elicited by erotic visual stimuli in patients treated with either Selective Serotonin Reuptake Inhibitors (SSRIs) or mirtazipine. METHODS: Nine middle-aged men with major depressive disorder treated with an SSRI and ten middle-aged men with major depressive disorder treated with mirtazapine completed the trial. Ten subjects with no psychiatric illness were included as a control group. We conducted functional brain magnetic resonance imaging (fMRI) while a film alternatively played erotic and non-erotic contents for 14 minutes and 9 seconds. RESULTS: The control group showed activation in the occipitotemporal area, anterior cingulate gyrus, insula, orbitofrontal cortex, and caudate nucleus. For subjects treated with SSRIs, the intensity of activity in these regions was much lower compared to the control group. Intensity of activation in the group treated with mirtazapine was less than the control group but grea-ter than those treated with SSRIs. Using subtraction analysis, the SSRI group showed significantly lower activation than the mirtazapine group in the anterior cingulate gyrus and the caudate nucleus. CONCLUSION: Our study suggests that the different rates of sexual side effects between the patients in the SSRI-treated group and the mirtazapine-treated group may be due to different effects on brain activation.
