BACKGROUND The fifth Millennium Development Goal (MDG 5) established the goal of a 75% reduction in the maternal mortality ratio (MMR; number of maternal deaths per 100,000 livebirths) between 1990 and 2015. We aimed to measure levels and track trends in maternal mortality, the key causes contributing to maternal death, and timing of maternal death with(More)
BACKGROUND The Millennium Declaration in 2000 brought special global attention to HIV, tuberculosis, and malaria through the formulation of Millennium Development Goal (MDG) 6. The Global Burden of Disease 2013 study provides a consistent and comprehensive approach to disease estimation for between 1990 and 2013, and an opportunity to assess whether(More)
BACKGROUND The Global Burden of Disease Study 2013 (GBD 2013) aims to bring together all available epidemiological data using a coherent measurement framework, standardised estimation methods, and transparent data sources to enable comparisons of health loss over time and across causes, age-sex groups, and countries. The GBD can be used to generate summary(More)
BACKGROUND The frequency of multiple sclerosis (MS) is still undetermined in Tehran. We conducted this survey to assess the incidence trend and point prevalence of MS on March 20, 2009, in Tehran province, Iran. METHODS Data for patients with a definite diagnosis of MS were obtained from the Iranian MS Society (IMSS). The annual incidence rates were(More)
BACKGROUND Iran was formerly considered to be located in a low prevalence zone for multiple sclerosis (MS). During the last decade the number of patients has increased. This study was conducted to estimate the prevalence of MS in the capital city of the country. METHODS We re-evaluated the files of all patients who had registered at the Iranian Multiple(More)
Natalizumab is an approved medication for highly active multiple sclerosis (MS). Progressive multifocal leukoencephalopathy (PML) may occur as a severe side effect of this drug. Here, we describe pathological and radiological characteristics of immune reconstitution inflammatory syndrome (IRIS), which occurs in natalizumab-associated PML after the cessation(More)
Progressive multifocal leukoencephalopathy (PML) is an uncommon and often fatal demyelinating disease of human central nervous system, which is caused by reactivation of the polyomavirus JC (JCV). PML generally occurs in patients with profound immunosuppression such as AIDS patients. Recently, a number of PML cases have been associated with administration(More)
Different research groups have extensively studied the associations of cytokine gene polymorphisms in different diseases. The role of cytokines gene polymorphisms in multiple sclerosis (MS), as a chronic Immune-mediated neurodegenerative disease, has been previously reported in the various populations. For determining pro-inflammatory cytokine gene(More)
Magnetic resonance imaging (MRI) is a sensitive paraclinical test for diagnosis and assessment of disease progression in multiple sclerosis (MS) and is often used to evaluate therapeutic efficacy. The formation of new T2-hyperintense MRI lesions is commonly used to measure disease activity, but lacks specificity because edema, inflammation, gliosis, and(More)
BACKGROUND High-dose intravenous methylprednisolone is the most common therapeutic modality to treat acute exacerbations in multiple sclerosis (MS). Various cardiac arrhythmias have been reported during corticosteroid pulse therapy. This study was conducted to detect cardiac rhythm changes in patients with MS while receiving high dose methylprednisolone. (More)
