RESUMO
Behcet's disease (BD) is a chronic systemic inflammatory vasculitis with a relapsing and remitting course. The disease predominantly affects males between the ages of 20 and 40 years. The disease is more prevalent in Middle Eastern and Asian countries but is less common in North American countries. BD typically presents as recurrent oro-genital ulcers and ocular inflammation. Pulmonary vasculitis with pulmonary arterial involvement is a unique manifestation, with most pulmonary manifestations occurring later in the disease course. Here, we report a case with pulmonary arterial aneurysms and variable arterial-venous thrombosis in a young African American Male diagnosed with BD after he presented with pulmonary manifestations. This report emphasizes that a high index of suspicion is needed to diagnose a rare condition with such variable manifestations as Behcet's disease and that early detection and immunosuppression therapy can confer improved prognosis.
RESUMO
We present a case of refractory hypernatremia in a patient with elevated adrenocorticotropic hormone (ACTH) and hypercortisolism. Cortisol's effect in tissues results in various outcomes, from maintaining blood pressure to increasing serum glucose levels. In addition, cortisol, cortisone, and aldosterone activate mineralocorticoid receptors with the same affinity; therefore, the activation of mineralocorticoid receptors by elevated cortisol levels leads to increased sodium reabsorption, increased potassium secretion, and metabolic alkalosis. Hypernatremia in our patient was initially refractory to fluid replacement but was eventually corrected with intravenous fluid and desmopressin. Overall, we suggest that hypercortisolism should be considered a differential diagnosis in hypernatremia refractory to fluids replacement.
RESUMO
Pylephlebitis, otherwise known as septic portal vein thrombosis, is an infective suppurative thrombosis of the portal vein and/or its intra-hepatic branches. It is a diagnosis that is frequently missed but easily treated with antibiotics. Therefore, it should be considered early on in any patient presenting with fever, abdominal pain, leukocytosis, and evidence of portal vein thrombosis on a CT scan. In this case report, we discuss a case of pylephlebitis as well as the etiologies, diagnosis, and treatment of septic portal vein thrombosis.
