Contemporary Pharmacotherapies for Nontuberculosis Mycobacterial Infections: A Narrative Review.

Nontuberculous mycobacteria (NTM) are a group of atypical bacteria that may cause a spectrum of clinical manifestations, including pulmonary, musculoskeletal, skin and soft tissue, and cardiac infections. Antimycobacterial medication regimens for NTM infections require multiple agents with prolonged treatment courses and are often associated with poor tolerance in patients and suboptimal clinical outcomes. This review summarizes NTM pharmacotherapy, including treatment concepts, preferred medication regimens according to NTM species and site of infection, and emerging treatment methods for difficult-to-treat species.

Nontuberculous Mycobacteria: Epidemiology and the Impact on Pulmonary and Cardiac Disease.

This article reviews the current epidemiology of nontuberculous mycobacterial pulmonary disease and the impact on thoracic disease. The prevalence of nontuberculous pulmonary disease in the United States is much higher than that of Mycobacterium tuberculosis. Estimates support an annual increase in incidence of 8% per year.

Necrotizing osteomyelitis in a man with disseminated infection.

Cases of disseminated nontuberculous mycobacterial (NTM) infection are difficult to treat. We encountered an elderly man with disseminated infection. The clinical evaluation and treatment of patients with this type of systemic infection pose unique challenges.

Plague in a Pediatric Patient: Case Report and Use of Polymerase Chain Reaction as a Diagnostic Aid.

We report a case of bubonic plaque in a 7-year-old patient who presented with a core temperature of 107°F, seizures, vomiting, altered mental status, and septic shock. This case highlights the utility of polymerase chain reaction (PCR) as a diagnostic aid for rapid presumptive identification of Yersinia pestis as well as the importance of correlating PCR results with clinical data. We discuss the various manifestations of plague as they relate to infection control, postexposure prophylaxis, antimicrobial therapy, and treatment duration.
