Brain Amygdala Volume Increases in Veterans and Active-Duty Military Personnel With Combat-Related Posttraumatic Stress Disorder and Mild Traumatic Brain Injury.

OBJECTIVE: To identify amygdalar volumetric differences associated with posttraumatic stress disorder (PTSD) in individuals with comorbid mild traumatic brain injury (mTBI) compared with those with mTBI-only and to examine the effects of intracranial volume (ICV) on amygdala volumetric measures. SETTING: Marine Corps Base and VA Healthcare System. PARTICIPANTS: A cohort of veterans and active-duty military personnel with combat-related mTBI (N = 89). DESIGN: Twenty-nine participants were identified with comorbid PTSD and mTBI. The remaining 60 formed the mTBI-only control group. Structural images of brains were obtained with a 1.5-T MRI scanner using a T1-weighted 3D-IR-FSPGR pulse sequence. Automatic segmentation was performed in Freesurfer. MAIN MEASURES: Amygdala volumes with/without normalizations to ICV. RESULTS: The comorbid mTBI/PTSD group had significantly larger amygdala volumes, when normalized to ICV, compared with the mTBI-only group. The right and left amygdala volumes after normalization to ICV were 0.122% ± 0.012% and 0.118% ± 0.011%, respectively, in the comorbid group compared with 0.115% ± 0.012% and 0.112% ± 0.009%, respectively, in the mTBI-only group (corrected P < .05). CONCLUSIONS: The ICV normalization analysis performed here may resolve previous literature discrepancies. This is an intriguing structural finding, given the role of the amygdala in the challenging neuroemotive symptoms witnessed in casualties of combat-related mTBI and PTSD.

Epidemiology profile of renal cell carcinoma: A 10-year patients' experience at King Abdulaziz Medical City, National Guard Health Affairs, Saudi Arabia.

PURPOSE: The purpose of this study is to describe the epidemiological profile, histopathological features, and outcomes of patients diagnosed with renal cell carcinoma (RCC) in a tertiary referral center over 10 years. METHODOLOGY: This is a retrospective cohort of 219 Saudi patients diagnosed with RCC between June 2003 and May 2013. The variables collected included the sociodemographic details and clinical presentation. The histopathological features investigated include the tumors histological subtype, pathologic staging tumor, node, and metastasis descriptors, and lymph-vascular invasion. Patients were followed until May 2013. Bivariable analysis was calculated using Chi-square test, with level of significance set at P < 0.05. Kaplan-Meier estimate was used to calculate the survival rate. RESULTS: The mean age of patients was 57.18 (±14.68 standard deviation). The trend of patients diagnosed with RCC over the past 10 years was higher among males than females (60.27% vs. 39.73%). Noticeably, more than half (57.58%) were diagnosed incidentally. The most common histological subtype was clear cell (conventional) RCC (70.44%). Patients were usually diagnosed at the pT1 stage (48.1%).The histopathological features associated with worse patient outcome were the stage of the primary tumor (P = 0.01) and lymph-vascular invasion (P = 0.003). The overall mean survival rate was 2.03 years. CONCLUSION: In the past 10 years, there are more patients diagnosed incidentally with RCC, which is in line with the global trend. Patients were more likely to be male and middle aged. We recommend further population-based studies in this area to establish a national epidemiological data for this common type of cancer.

Depression literacy in women attending university hospital clinics in Riyadh Saudi Arabia.

BACKGROUND: Depression literacy in general population constitutes an ability to understand depression, with knowledge of disease, its risk factors and symptoms. High levels of depression literacy promote early intervention, potentially reducing related disability. AIM: This study investigated the depression literacy in women visitors to clinics of a tertiary care hospital in Riyadh, Saudi Arabia. METHODS: Women of 18 and more years were surveyed during their visit to primary and other healthcare clinics of a public hospital in Riyadh. Knowledge on depression symptoms, causes and management approaches identified depression literate women scoring more than 30 points on a 42-item tool. RESULTS: Of the 409 participants, 65.5% were depression literate, 50% educated as college and above, 64.3% married, 50.7% housewives, 62.4% reported use of multiple information sources (range, 0-8) and had a mean age of 34.9 (standard deviation ( SD), 12.4) years. In a logistic regression model, participants scoring less than 30 for depression literacy were significantly associated with women having less than college-level education, divorced marital status and use of decreasing number of learning resources. CONCLUSION: Women with low education divorced; using fewer information sources need specific considerations by healthcare providers for assessment of depressive disorders in this setting.
