A Case of Mitochondrial Neurogastrointestinal Encephalomyopathy with Metabolic Complications During Refeeding.

BACKGROUND Anorexia nervosa has been referred to as the "great pretender" of medicine and is often misdiagnosed. We present a rare genetic disorder that was misdiagnosed as anorexia nervosa. This case highlights the diagnosis of mitochondrial neurogastrointestinal encephalomyopathy in a patient with previously diagnosed anorexia nervosa, which was discovered due to the metabolic abnormalities and intolerance of nutrition encountered during refeeding.

A Comprehensive Review of Complications and New Findings Associated with Anorexia Nervosa.

Anorexia nervosa is a complex and deadly psychiatric disorder. It is characterized by a significant degree of both co-occurring psychiatric diseases and widespread physiological changes which affect nearly every organ system. It is important for clinicians to be aware of the varied consequences of this disorder.

Nontuberculous mycobacterial lung infections in patients with eating disorders: plausible mechanistic links in a case series.

Nontuberculous mycobacteria (NTM) are widely distributed in the environment and are almost always acquired into the lungs by bioaerosol inhalation or aspiration of NTM-contaminated water, biofilms, and soil. NTM are increasingly recognized as causes of lung diseases in immunocompetent hosts, a not insignificant number of whom have a life-long or nearly life-long slender body habitus as well as thoracic cage abnormalities such as scoliosis and pectus excavatum. While several hypotheses have been offered to explain the purported increase in susceptibility to NTM lung disease in such individuals, the precise explanation remains unknown.
