The choice of reference point for computing sagittal plane angular momentum affects inferences about dynamic balance

Background Measures of whole-body angular momentum in the sagittal plane are commonly used to characterize dynamic balance during human walking.To compute angular momentum, one must specify a reference 30x24x24 wall cabinet point about which momentum is calculated.Although biomechanists primarily compute angular momentum about the center of mass (C

Pulmonary Talcosis in an Immunocompromised Patient

The first case of pulmonary talcosis or talc pneumoconiosis related to inhalation of talc during its extraction and processing in mines was described by Thorel in 1896.Pulmonary talcosis is most commonly seen secondary to occupational exposure or intravenous (IV) drug abuse and, occasionally, in excessive use of cosmetic talc.Based on literature re
