BACKGROUND Mobile (cell) phone communication has been suggested as a method to improve delivery of health services. However, data on the effects of mobile health technology on patient outcomes in resource-limited settings are limited. We aimed to assess whether mobile phone communication between health-care workers and patients starting antiretroviral(More)
We examined trends in fracture rates over 20 years in the Province of Manitoba, Canada. Hip fractures, major low-trauma fractures, and high-trauma fractures declined significantly from 1986 to 2006. Secular decreases in hip fracture rates have been reported in some countries. Whether this phenomenon applies to other fracture sites is not well described. We(More)

BACKGROUND Treatment outcomes for multidrug-resistant Mycobacterium Tuberculosis (MDRTB) are generally poor compared to drug sensitive disease. We sought to estimate treatment outcomes and identify risk factors associated with poor outcomes in patients with MDRTB. METHODOLOGY/PRINCIPAL FINDINGS We performed a systematic search (to December 2008) to(More)
BACKGROUND Inhaled corticosteroids (ICS) are commonly prescribed medications for the management of asthma and chronic obstructive pulmonary disease. It is well established that long-term use of these drugs may lower bone mineral density. However, whether ICS increase the risk of fractures remains unknown. Recent studies that have attempted to explore this(More)
BACKGROUND Myasthenic crisis is the most serious life-threatening event in generalized myasthenia gravis (MG) patients. The objective of this study was to assess the long-term impact of thymectomy on rate and severity of these attacks in Iranian patients. METHODS We reviewed the clinical records from 272 myasthenic patients diagnosed and treated in our(More)
