Lafora disease (LD) can be diagnosed by skin biopsy, but this approach has both false negatives and positives. Biopsies of other organs also diagnostic are more invasive. Genetic diagnosis is possible inconclusive, for example, in patients with only one heterozygous <i>EPM2A</i> mutation apparently homozygous <i>EPM2B</i> mutations where parent not a carrier the mutation. We sought to identify occult clarify genotypes confirm LD apparent nonrecessive inheritance. used single nucleotide...

Abstract Introduction Work disability is a major consequence of rheumatoid arthritis (RA), associated not only with traditional disease activity variables, but also more significantly demographic, functional, occupational, and societal variables. Recent reports suggest that the use biologic agents offers potential for reduced work rates, conclusions are based on surrogate measures derived from studies primarily Western countries. Methods The Quantitative Standard Monitoring Patients RA...

Spine-related disorders are a leading cause of global disability and burden on society to public health. Currently, there is no comprehensive, evidence-based model care for spine-related disorders, which includes back neck pain, deformity, spine injury, neurological conditions, spinal diseases, pathology, that could be applied in health settings. The purposes this paper propose: (1) principles transform the delivery care; (2) an globally; (3) implementation suggestions. Global Spine Care...
