RESUMEN
Brachytherapy consists of placing radioactive sources into or adjacent to tumors, to deliver conformal radiation treatment. The technique is used for treatment of primary malignancies and for salvage in recurrent disease. Permanent prostate brachytherapy seeds are small metal implants containing radioactive sources of I-125, Pd-103, or Cs-131 encased in a titanium shell. They can embolize through the venous system to the lungs or heart and subsequently be detected by cardiovascular computed tomography. Cardiovascular imagers should be aware of the appearance of migrated seeds, as their presence in the chest is generally benign, so that unnecessary worry and testing are avoided. We report a case of a patient who underwent brachytherapy for prostate cancer and developed a therapeutic seeds embolus to the right ventricle.
RESUMEN
Dialectical behavior therapy (DBT) and dynamic deconstructive psychotherapy (DDP) are listed in the National Registry of Evidence-Based Programs and Practices based on their performances in randomized controlled trials. However, little is known about their effectiveness in real-world settings. In the present study, the authors observed the naturalistic outcomes of 68 clients with borderline personality disorder (BPD) who were treated at a medical university clinic by experienced therapists using either comprehensive DBT (n = 25) or DDP (n = 27), with 16 clients treated with unstructured psychotherapy serving as a control. We found both DBT and DDP achieved significant reductions in symptoms of BPD, depression, and disability by 12 months of treatment, and showed effect sizes consistent with controlled trials. However, attrition from DBT was high and DDP obtained better outcomes than DBT (d = .53). Larger effectiveness studies are needed to replicate these findings, delineate common and unique treatment processes, and determine therapist and patient characteristics predicting positive outcomes.

Background Since the first cardiac catheterization in 1929, the procedure has continually evolved with advances in understanding, capabilities, and ease of operation. Though historically performed by cut down of the brachial artery, cardiologists soon learned that transfemoral access was both easier to perform and more efficacious with regard to patient outcome. In the last 20 years, the transradial approach has been adopted, and is being utilized with increasing frequency. Methods We conducted a survey of literature published concerning safety, efficacy, cost-effectiveness, and global uptake of transradial catheterization with specific attention to how transradial interventions compare with transfemoral interventions. Results This review of literature indicates that when performed by an experienced interventionalist, radial catheterization is as effective as femoral catheterization and has additional benefits of shorter length of hospital stay and reduced patient costs. Transradial access is superior to transfemoral access in some, but not all, clinical scenarios; in addition, it is an effective alternative for catheterization in patients contraindicated for transfemoral procedures. Adoption of radial access in the United States is at a faster rate than previously expected, though rate of use varies drastically worldwide. Conclusion The transradial approach is an excellent option for carrying out cardiovascular interventions, and will be adopted by more cardiologists in the upcoming years.

The Dopamine Hypothesis of Schizophrenia is actively being challenged by the NMDA Receptor Hypofunctioning Hypothesis of Schizophrenia. The latter hypothesis may actually be the starting point in neuronal pathways that ultimately modifies dopamine pathways involved in generating both positive and negative symptoms of schizophrenia postulated by the former hypothesis. The authors suggest that even this latter, NMDA receptor-based, hypothesis is likely too narrow and offer a review of typical glutamate and dopamine-based neurocircuitry, propose genetic vulnerabilities impacting glutamate neurocircuitry, and provide a broad interpretation of a possible etiology of schizophrenia. In conclusion, there is a brief review of potential schizophrenia treatments that rely on the etiologic theory provided in the body of the paper.
RESUMEN
The Dopamine Hypothesis has been the leading theory used to explain the mechanism of the clinical manifestation of schizophrenia symptoms for decades. It is unclear if excess dopaminergic activity is the primary pathophysiology causing psychosis or if this dopamine excess is triggered by upstream, downstream or neurodevelopmental abnormalities. A corollary hypothesis suggests that the glutamatergic system may be involved in the pathogenesis of schizophrenia, and that dysfunction of the glutamate system may actually lead to dopamine excess. The NMDA Receptor Hypofunction Hypothesis suggests that malfunctioning NMDA receptors may be the cause for the theoretically hypofunctioning glutamate system. This paper seeks to describe and discuss the potential underlying genetic vulnerabilities of the NMDA receptor and how aberrant genes coding for this receptor may lead to schizophrenia symptoms.
