RESUMEN
A small subset of patients with antiphospholipid syndrome (APS) may develop widespread thrombotic disease with organ damage, referred to as catastrophic APS (CAPS) that is associated with a high mortality. Medical therapy typically involves a combination of anticoagulation, systemic glucocorticoids, plasmapheresis, and intravenous immune globulin (IVIG). There is currently no consensus for the management of refractory cases of CAPS. However, monoclonal antibodies such as rituximab and eculizumab have shown some benefits. Herein, we present a 29-year-old female with previous pulmonary embolism who presented with necrotic left toes and was eventually diagnosed with refractory CAPS, successfully treated with Plasmapheresis and Rituximab. With this case report, we hope to encourage the usage of Rituximab in the management of CAPS.
RESUMEN
Research on the brain regions involved in suicidal behavior has led to the identification of a number of regions as being implicated in the neurobiology of suicide. Some of the brain regions identified have a clear correlation between the levels of activity and suicidal behavior. For some regions, such as the insular cortex and anterior cingulate cortex (ACC), both hyperactivity and hypoactivity have been correlated with suicidal behavior. More studies are needed to characterize more clearly the activity of the insular cortex and ACC when it comes to suicidal behavior. The case report presented adds to the literature seeking to clarify the correlation between ACC and insular activities and suicidal behavior. Structural damage of the insular region and ACC, thus leading to a decline in their activity level, was found in a patient who had resolution of suicidal intent after hypoxic brain injury. We discuss the significance of our findings for the neurobiology of suicide.
