Monitoring the performance of mycobacteriology laboratories: a proposal for standardized indicators

SETTING: Thailand Tuberculosis (TB) Active Surveillance Network: Bangkok, Chiang Rai, Phuket, Tak and Ubon-Ratchathani, Thailand. BACKGROUND: Mycobacteriology laboratories in resource-limited, high TB burden settings are expanding to perform conventional solid media culture and broth-based mycobacteriology culture. Indicators that measure how well a laboratory performs sputum microscopy have been developed and broadly implemented. Routine monitoring of sputum culture performance, however, is not as common. DESIGN: We implemented indicators for monitoring the quality of laboratory services in five province-level mycobacteriology culture facilities in Thailand. These indicators were derived from literature review, consultation with subject matter experts and our program experience. CONCLUSIONS: We believe that an international consensus document providing monitoring guidelines for mycobacteriology laboratories is urgently needed.     

Hyperammonemic coma in a post-partum patient with undiagnosed urea cycle defect

Urea cycle disorders (UCD) are common during neonatal period, and it is rarely reported in adults. We are reporting a patient presenting with post-partum neuropsychiatric symptoms rapidly progressing to coma. Markedly raised serum ammonia level on presentation with an initial normal magnetic resonance imaging (MRI) of brain and normal liver function tests led to the suspicion of UCD, which was confirmed on the basis of urine orotic acid and elevated serum amino acid levels. We had to resort to hemodialysis to correct the hyperammonemic coma, which was unresponsive to conventional anti-ammonia measures. She exhibited remarkable improvement with a progressive decline in serum ammonia with repeated hemodialysis and made a full recovery. Timely diagnosis and early institution of hemodialysis in the setting of a poor neurological status maybe considered a suitable treatment option.
