HIV/AIDS patients often present with orogenital ulcers. In the immunocompromised patient diagnosis of these ulcers pose a challenge, as there is a myriad of etiologies. We present a case of an HIV/AIDS patient with recurrent orogenital aphthosis that was confirmed to have concomitant diagnosis of Behcet's disease. Proper awareness of the causes of these ulcers is essential for prompt and effective treatment. While rare causes may be at the bottom of a differential list in an immunocompetent host, when HIV/AIDS is involved these rare causes often percolate to the top.

The combination of Von Recklinghausen disease with a pheochromocytoma has a genetic linkage but is an exceedingly rare occurrence. Von Recklinghausen disease or neurofibromatosis type 1 (NF1) is a neurocutaneous disorder characterized by cafe-au-lait macules and multiple, soft tissue neurofibromas. While a pheochromocytoma is a neuroendocrine tumor characterized by intermittent hypertension. NF1 predisposes patients to pheochromocytomas; however, this occurrence is extremely rare. We describe the case of a young male with neurofibromatosis and a pheochromocytoma.

Aerococcus urinae is a rare bacteria usually associated with urinary tract infection. It is unusually associated with endocarditis. To date only 18 cases have been reported. Among these cases, the majority had aortic valve involvement. Three had mitral and aortic valve involvement, and two had mitral and tricuspid valve involvement. We present the first reported case of A. urinae associated aortic and tricuspid valve endocarditis. Timely recognition and appropriate treatment of this fatal infection is essential to decrease morbidity and mortality.

We report the case of a 47 year-old female with Streptococcus agalactiae (Group B beta-hemolytic streptococcus) meningitis complicated by hemorrhagic stroke. The patient presented to the emergency department with altered mental status, agitation, confusion, respiratory distress and fever of one-day duration. Labs showed left shift leukocytosis. CSF exhibited a high white blood cell count with a predominant population of polymononuclear cells, high glucose and protein concentration. CSF cultures grew S. agalactiae. Despite appropriate antimicrobial treatment, her mental status did not improve and head CT showed two hemorrhages, diffuse cerebral edema and a right to left midline shift. After completing the course of her therapy, her mental status improved and the patient was discharged.
