RESUMEN
Adrenocortical carcinoma (ACC) is a rare malignancy with an estimated annual incidence of 0.7-2 cases per million. Most patients present with steroid hormone excess or abdominal mass effects, but 15% of patients with ACC are diagnosed incidentally. A careful history, physical exam, and pertinent lab investigations are necessary to reach the diagnosis. Surgical resection is the cornerstone of treatment in localized ACC; however, systemic chemotherapy with mitotane is preferred in patients with widespread disease or those who are not ideal candidates for surgery.

Tuberculosis (TB) is an important cause of morbidity and mortality in the United States. Due to the unpredictable or nonspecific nature of its clinical presentations, TB can be a diagnostic challenge for physicians. In 2013, 23% of reported TB cases were culture-negative in the United States; in New York City, this was approximately 27%. The increasing number of sputum smear- and culture-negative TB patients is a serious concern because misdiagnosis and delayed treatment can lead to increased morbidity and mortality and increased infectious transmission. We report a case of a 26-year-old-female recent immigrant, who was initially managed for community-acquired pneumonia but was later found to have TB with complicated pleural effusion, despite having multiple smear- and culture-negative sputum specimens, Xpert Mycobacterium tuberculosis (MTB)/resistance to rifampin (RIF) assay (real-time polymerase chain reaction (PCR)) and pleural fluid analysis. She improved clinically on anti-tuberculosis therapy and, later, the diagnosis was confirmed by pleural biopsy.
RESUMEN
Late prosthetic valve endocarditis is usually caused by streptococci, staphylococci, gram-negative bacilli and candida. The authors report the first case of prosthetic valve endocarditis caused by Gemella sanguinis. The patient's risk factors for the development of Gemella endocarditis were the persistent severe dental caries and the presence of prosthetic valves. The patient required surgical replacement of the infected valve but had a good outcome with preservation of cardiac and valvular function. Evaluation and treatment of the persistent dental infection before initial valvular surgery may have prevented secondary infection of the prosthetic valve.
