This study, a retrospective review of 165 patients with myasthenia gravis, compares the course of the disease for patients with onset before 50 and at or after 50. There were no significant differences between age groups for presenting symptoms, but more of the older patients had progressed to severe disease. More of the younger than the older patients were(More)
Myeloproliferative neoplasms (MPNs) are a heterogeneous group of diseases including polycythemia vera (PV), essential thrombocythemia (ET), and primary(idiopathic) myelofibrosis (PMF). In this systematic review, we provide a comprehensive report on the incidence and prevalence of MPNs across the globe. Electronic databases (PubMed, EMBASE, MEDLINE, and Web(More)
In spite of a decline in muscle strength with age, the cause of the overall decrease in motor performance in aged mammals, including rodents, is incompletely understood. To add clarity, the gross organization, innervation, histochemical fiber types, and age-associated changes are described for mouse forearm muscles used in a variety of motor functions. The(More)
The case of a 5-year-old girl who survived a near-fatal ingestion of yew plant leaves after treatment with CPR, transcutaneous pacing, and digoxin-specific FAB antibody fragments is presented. Multiple rhythm disturbances, including profound bradycardia, occurred. She required endotracheal intubation, external chest compressions, and application of a(More)
BACKGROUND Transcutaneous cardiac pacemakers generate electrical stimuli that pace the heart through external electrodes that adhere to the chest wall. Transcutaneous pacing has been useful in some patients with bradycardia, but its efficacy in patients with asystole and full cardiac arrest has been limited, possibly because of delays in the initiation of(More)
STUDY OBJECTIVE To evaluate the effectiveness of transcutaneous cardiac pacing in out-of-hospital treatment of cardiac arrests in pediatric patients. DESIGN We describe the outcome of patients treated during a prospective trial of transcutaneous cardiac pacing in the field. We compare their outcome with that of out-of-hospital arrests in submersion(More)
Given the high costs of conducting a drug-response trial, researchers are now aiming to use retrospective analyses to conduct genome-wide association studies (GWAS) to identify underlying genetic contributions to drug-response variation. To prevent confounding results from a GWAS to investigate drug response, it is necessary to account for concomitant(More)
The purpose of the current study was to determine the relationships between lifetime physical activity participation, neuromuscular performance and body composition in men at musculoskeletal maturity. 50 healthy men (age 25.2±4.5 years) volunteered to participate. Lifetime physical activity was determined from the Bone-specific Physical Activity(More)
