RESUMEN
BACKGROUND: Identifying individuals at increased risk of suicide is important, particularly those who present for treatment for nonpsychiatric chief complaints who may go undetected. It has been found that pain symptoms, such as headache, are associated with suicide, although this association requires further characterization. This study examined specific components of suicidality in relation to headache subtypes. METHODS: This study retrospectively reviewed 2,832,835 nonpsychiatric adult clinical encounters at a large county hospital, where a standardized suicide risk screening tool, the Columbia-Suicide Severity Rating Scale (C-SSRS), was universally implemented. The C-SSRS assesses specific components of suicidality: wish to be dead and suicidal ideation, method, intent, plan, and action. Multivariate logistic regressions were performed to assess the association between headache, as well as headache subtype (migraine, tension, or cluster), and each component of suicidality. RESULTS: There were significant positive associations between presenting with a headache and 2 specific components of suicidality: wish to be dead and suicidal action. Individuals with tension headache may have a lower risk of wishing to be dead compared to those with migraine and cluster headaches. CONCLUSIONS: The association of headaches with specific elements of sui-cidality demonstrates the potential yield of identification of suicide risk among individuals with nonpsychiatric presentations.

Our earlier decorin (Dcn) gene overexpression studies found that the targeted Dcn gene transfer into the cornea inhibited corneal angiogenesis in vivo using a rabbit model. In this study, we tested the hypothesis that anti-angiogenic effects of decorin in the cornea are mediated by alterations in a normal physiologic balance of pro- and anti-angiogenic factors using decorin deficient (Dcn-/-) and wild type (Dcn+/+) mice. Corneal neovascularization (CNV) in Dcn-/- and Dcn+/+ mice was produced with a standard chemical injury technique. The clinical progression of CNV in mice was monitored with stereo- and slit-lamp microscopes, and histopathological hematoxylin and eosin (H&E) staining. Protein and mRNA expression of pro- and anti-angiogenic factors in the cornea were evaluated using immunofluorescence and quantitative real-time PCR, respectively. Slit-lamp clinical eye examinations revealed significantly more CNV in Dcn-/- mice than the Dcn+/+ mice post-injury (p < 0.05) and AAV5-Dcn gene therapy significantly reduced CNV in Dcn-/- mice compered to no AAV5-Dcn gene therapy controls (p < 0.001). H&E-stained corneal sections exhibited morphology with several neovessels in injured corneas of the Dcn-/- mice than the Dcn+/+ mice. Immunofluorescence of corneal sections displayed significantly higher expression of α-smooth muscle actin (α-SMA) and endoglin proteins in Dcn-/- mice than Dcn+/+ mice (p < 0.05). Quantitative real-time PCR found significantly increased mRNA levels of pro-angiogenic factors endoglin (2.53-fold; p < 0.05), Vegf (2.47-fold; p < 0.05), and Pecam (2.14-fold; p < 0.05) and anti-angiogenic factor Vegfr2 (1.56-fold; p < 0.05) in the normal cornea of the Dcn-/- mice than the Dcn+/+ mice. Furthermore, neovascularized Dcn-/- mice corneas showed greater increase in mRNA expression of pro-angiogenic factors endoglin (4.58-fold; p < 0.0001), Vegf (4.16-fold; p < 0.0001), and Pdgf (2.15-fold; p < 0.0001) and reduced expression of anti-angiogenic factors Ang2 (0.12-fold; p < 0.05), Timp1 (0.22-fold; p < 0.05), and Vegfr2 (0.67-fold; p > 0.05) compared to neovascularized Dcn+/+ mice corneas. These gene deficience studies carried with transgenic Dcn-/- mice revealed decorin's role in influencing a physiologic balance between pro-and anti-angiogenic factors in the normal and injured cornea. We infer that the functional deletion of Dcn promotes irregular corneal repair and aggravates CNV.

Major depressive disorder is associated with pro-inflammatory markers, such as cytokines TNF-alpha, IL-6, IL-1ß, and C-reactive protein. Galectin-3 is a novel emerging biomarker with pro-inflammatory properties. It is a saccharide binding protein distributed throughout many tissues with varying functions and is a predictor of poor outcomes in patients with heart failure and stroke. However, its role as a predictor in depressive symptom severity remains undefined. Data from the community-based Dallas Heart Study (n = 2554) were examined using a multiple linear regression analysis to evaluate the relationship between galectin-3 and depressive symptom severity as assessed with Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR) scores. Additional covariates included age, sex, race/ethnicity, body mass index (BMI), years of education, serum creatinine, history of diabetes, and smoking history. Galectin-3 levels statistically significantly predicted QIDS-SR depressive symptom severity (ß = 0.055, p = .015). Female sex, smoking status, and BMI were found to be statistically significant positive predictors of depression severity, while age, years of education, non-Hispanic White race, and Hispanic ethnicity were negative predictors of depressive symptom severity. In this large sample, higher galectin-3 levels were associated with higher levels of depressive symptoms. The findings suggest that galectin-3 may be a new and useful inflammatory biomarker associated with depression.

Over the last few decades in health care a premium has been placed on decreasing the length of stay. Cost containment measures and more effective psychotropic medications have fueled this trend. The new paradigm is "diagnose, stabilize quickly, and discharge to outpatient setting." Although in the short run this model saves money, it is at the cost of an accurate diagnosis; however, in the long run the costs far exceed the initial savings, especially in today's dismal economy. This editorial presents a case report where prolonged psychiatric hospitalization and diagnostic clarification saved the U.S. Air Force $650,000 in unwarranted disability payments.

In line with Psychiatry 2009's mission to strengthen its global presence as a leading source of evidence-based information for practicing clinicians, we are pleased to launch the new column, "Psychiatric Clinics from Around the World." This series will enable readers to become familiar with facilities around the world that provide psychiatric care. We hope you find the column interesting. We start the series with a column featuring Wilford Hall Medical Center, the flagship psychiatric facility of the United States Air Force.United States Air Force psychiatry plays a vital role in Operation Iraqi Freedom and Operation Enduring Freedom (Afghanistan). Outside of the military, little is known about US Air Force psychiatry and the Wilford Hall Medical Center. Wilford Hall Medical Center is the US Air Force's flagship hospital and premiere psychiatric hospital. This article briefly discusses the history of Wilford Hall Medical Center and its psychiatric contributions to the wars in Iraq and Afghanistan.
RESUMEN
The use of complimentary/alternative medicine has become popular as evidenced by grocery store aisles and "infomercials" devoted to herbal products. These products are often misconstrued as safe because of their natural origin. With an increase in the consumption of these products, physicians need to be aware of their potential adverse effects. There are several popular over-the-counter herbal products that can affect one's behavior, especially resulting in acute mania and/or psychosis. This article provides an overview of existing literature regarding the increased use of herbal agents, reviews several case reports describing a potential association between herbal products (St. John's Wort and ginseng) and the development of mania and psychosis, and discusses the limitations in determining the frequency of serious adverse effects due to herbal products.
