Left atrial thrombus after placement of watchman device.

Atrial fibrillation is an irregular rhythm with increased risk of morbidityand mortality. Commonly due to thromboembolism at the left atrialappendage. Guideline therapy for atrial fibrillation is anticoagulation.Alternative treatment includes closure with the Watchman device. Wepresent a case of Watchman device-related thrombus seven monthsafter placement.

Hemophagocytic lymphohistiocytosis secondary to disseminated histoplasmosis, cytomegalovirus viremia, and nontuberculous mycobacteria bacteremia in a patient with recently diagnosed AIDS.

A 30-year-old Honduran male with recently diagnosed AIDS presented with a 1-month history of worsening abdominal pain, diarrhea, and fever. Initial investigations were notable for Cytomegalovirus viremia and diffuse lymphadenopathy. Axillary lymph node biopsy demonstrated necrotizing lymphadenitis with disseminated histoplasmosis. Despite aggressive antimicrobial therapy he continued to clinically deteriorate raising suspicion for hemophagocytic lymphohistiocytosis. The patient met 5 of 8 HLH-2004 diagnostic criteria and was successfully treated with dexamethasone and etoposide per the HLH-94 protocol. Despite the high mortality rates and poor clinical outcomes of hemophagocytic lymphohistiocytosis in patients living with HIV/AIDS, this case demonstrates that this high-risk patient population can be successfully treated and survive acquired hemophagocytic lymphohistiocytosis. Furthermore, our case stresses the importance of maintaining a broad differential diagnosis in patients living with HIV/AIDS who present with sepsis.

Takotsubo Cardiomyopathy Secondary to Cryptococcal Meningoencephalitis in a Patient With Multiple Sclerosis.

Takotsubo or stress-induced cardiomyopathy is described as reversible left ventricular dysfunction that develops following a stressful emotional or physical event primarily occurring in postmenopausal females. Many physiologic triggers have been identified in the pathogenesis of Takotsubo cardiomyopathy, including diseases which affect the central nervous system such as traumatic brain injuries, hemorrhagic and ischemic strokes, epilepsy, and central nervous system infections, including meningitis and encephalitis; however, there are very few published case reports of Takotsubo cardiomyopathy in the setting of fungal meningoencephalitis. We present a unique case of Takotsubo cardiomyopathy secondary to Cryptococcus neoformans meningoencephalitis in a middle-aged female with a history of multiple sclerosis who was taking immunosuppressive therapy.
