We present the case of a 38-year-old man with end-stage renal disease receiving hemodialysis via a left femoral loop graft who developed debilitating back pain. During a maintenance fistulogram, we found a completely occluded inferior vena cava and engorged lumbar veins. The patient underwent inferior vena cava reconstruction with stenting, which resulted in complete resolution of the engorged lumbar veins on venography and a significant reduction in his back pain.

Gender norms related to sexual behavior have a pervasive impact on the psychosocial development of men. These norms have been theorized to influence the formation of male sexual scripts, including those that place high emphasis on performative abilities. While research has indicated that endorsing performance-based scripts can have negative consequences, little work has examined how this sexual ideology is communicated by men to their peer groups.

Decades of masculinity research have concluded that society places higher demands on males to adhere to norms for low emotional expression; yet, countless studies find that emotional expression is integral to well-being. Unfortunately, this contradiction places boys and men in a tenuous position as they must navigate a bombardment of societal messages about the importance of emotional stoicism and invincibility. For urban adolescents, the situation is more complicated as they encounter environmental stressors that place greater emphasis on projecting a tough façade.

Men are considerably less likely to seek professional and nonprofessional help for mental disorders. Prior findings indicate that adherence to masculine norms contributes to stigma about internalizing disorders and help seeking. There are currently no empirically supported interventions for increasing help seeking in men with internalizing symptoms.

Absence of the inferior vena cava (AIVC) is a rare congenital anomaly and result from aberrant development during embryogenesis. Deep vein thrombosis (DVT) is a frequent finding in healthy young adults who are diagnosed with congenital AIVC. This condition is best diagnosed with color venous Doppler ultrasound and computed tomography angiography or magnetic resonance imaging, and managed using anticoagulation, mechanical catheter-directed thrombectomy, and thrombolysis.

There has been limited research on interventions addressing the psychosocial barriers to men's underutilization of formal and informal help. To address this gap in the literature, we report on the development of Gender-Based Motivational Interviewing (GBMI) for men with internalizing symptoms and present the findings of a pilot trial. GBMI is a single session of assessment and feedback that integrates gender-based and motivational interviewing principles.

The occurrence of status epilepticus (SE) is considered the main cause of brain lesions and morphological alterations, such as hippocampal neuron loss, that result in chronic epilepsy. Previous work demonstrated the convulsive and widespread neuropathological effects of soman, an organophosphorus compound that causes SE and severe recurrent seizures as a result of exposure. Seizures begin rapidly after exposure, can continue for hours, and contribute to prolonged physical incapacitation of the victim.

A 62-year-old male with multiple medical problems including a long-standing history of muscular dystrophy presented with recurrent abdominal and back pain of 2-month duration. Two consecutive mesenteric arteriograms were performed 3 weeks apart as part of the work-up and treatment. The latest study revealed a significant progression in the size and number of visceral artery aneurysms.

Background: Chimeric proteins may be used to direct cell-specific activity. Heparin-binding growth-associated molecule (HBGAM) binds to cell receptors that are relatively more robust on endothelial cells, and it may confer endothelial cell selectivity to potent angiogens such as fibroblast growth factor-1 (FGF-1).

Methods: By ligating fibroblast growth factor or its potent mutant, S130K, to HBGAM, we tested their effect on re-endothelialization after angioplasty injury by using a canine model.

Antidepressant medication is considered the current standard for severe depression, and cognitive therapy is the most widely investigated psychosocial treatment for depression. However, not all patients want to take medication, and cognitive therapy has not demonstrated consistent efficacy across trials. Moreover, dismantling designs have suggested that behavioral components may account for the efficacy of cognitive therapy.

Aortoenteric fistula (AEF) is an infrequent but disastrous complication of open abdominal aortic repair. Left untreated, it has a 100% fatality rate. The traditional approaches to the repair of secondary AEF (SAEF) are associated with average mortality rates of 21-59% and numerous major complications.

Objectives: Abdominal aortic aneurysm (AAA) sac shrinkage after endovascular aneurysm repair (EVAR) is considered to be evidence of clinical success. Exclusion of the sac from systemic pressure is the likely cause of shrinkage. We report our continuing clinical experience with the use of a permanently implantable, ultrasound-activated remote pressure transducer to measure intrasac pressure and its correlation with changes in sac diameter over time.

Minimally invasive repair of thoracic and abdominal aortic aneurysms (AAAs) is rapidly becoming a vital tool in the arsenal of the vascular specialist. Historically, surgical replacement of the aorta has been the "gold standard" for treatment of aortic aneurysms. However, transfemoral placement of an endovascular stent graft, first described by Dr.

Clinical researchers and practitioners are increasingly aware of the need for quality theory, research, and intervention in men's mental health. Successful work in this area requires an understanding of the multitude of ways that gender, and more specifically masculinities, can be conceptualized beyond a sole focus on sex differences between men and women. Drawing from a range of social sciences in addition to psychology, the authors consider several theoretical, research, and clinical directions that can follow from social learning, psychodynamic, social constructionist, and feminist paradigms.

Recent research into reason giving for depression has illustrated the importance of client beliefs about the cause of their depression. Reasons given have been found to be associated with level of depression, perceived credibility of treatments and therapy outcome. It has been suggested that giving reasons for depression is a form of rule-governed behaviour and as such can cause the depression to be harder to treat (i.

Objectives: Endovascular stent graft repair of abdominal aortic aneurysms (AAAs) prevents rupture by excluding the aneurysm sac from systemic arterial pressure. Current surveillance protocols after endovascular aneurysm repair (EVAR) follow secondary markers of sac pressurization, namely, endoleak and sac enlargement. We report the first clinical experience with the use of a permanently implantable, ultrasound-activated remote pressure transducer to measure intrasac pressure after EVAR.

Eighty clients enrolled in a managed care health plan who identified panic disorder as their primary presenting problem were randomly assigned to treatment by a therapist recently trained in a manual-based empirically supported psychotherapy or a therapist conducting treatment as usual (TAU). Participants in both conditions showed significant change from pre- to posttreatment on a number of measures. Those receiving panic control therapy (PCT) showed greater levels of change than those receiving TAU.

Research on men's help seeking yields strategies for enhancing men's use of mental and physical health resources. Analysis of the assumptions underlying existing theory and research also provides a context for evaluating the psychology of men and masculinity as an evolving area of social scientific inquiry. The authors identify several theoretical and methodological obstacles that limit understanding of the variable ways that men do or do not seek help from mental and physical health care professionals.
