Disseminated nontuberculous mycobacterial infection in the context of interferon-gamma autoantibody syndrome: A case report and review of the literature.

Interferon-gamma (IFN-γ) autoantibody syndrome is an emerging clinical entity that has been associated with disseminated non-tuberculous mycobacterial infection (dNTM) particularly in healthy young people, a population not previously thought to be at particular risk. A 29-year-old South-East Asian man presented with several weeks of fever, cough, lymphadenopathy, and constitutional symptoms while working on an international cargo ship, deteriorating rapidly with a sepsis-like syndrome. Eventually lymph node and sputum cultures revealed a diagnosis of dNTM infection with growth of both Mycobacterium persicum and Mycobacterium abscessus.

This case describes a previously unreported complication of maxillary canine root canal therapy in a cat. A 5-year-old Russian Blue cat was presented with a complicated crown fracture (pulp exposure) of its left maxillary canine tooth (204).

Pulmonary malakoplakia due to Prescottella (Rhodococcus) soli in a renal transplant recipient: First reported case.

Prescottella (Rhodococcus) soli is a soil-dwelling organism not previously thought to be pathogenic in humans. We discuss the case of a 78-year-old male renal transplant recipient presenting with respiratory symptoms and multiple pulmonary nodules, found to be pulmonary malakoplakia secondary to infection with Prescottella (Rhodococcus) soli. Treatment was commenced with vancomycin, meropenem and azithromycin for an induction period of two weeks and continued with indefinite oral moxifloxacin and azithromycin with significant clinical improvement.
