Management Approaches To Spastic Gait Disorders, Sheng Li, Tulsi Pandat, Bradley Chi, Daniel Moon, Manuel Mas

Faculty, Staff and Student Publications

Spastic gait presents clinically as the net mechanical consequence of neurological impairments of spasticity, weakness, and abnormal synergies and their interactions with the ground reaction force in patients with upper motor neuron syndromes and with some neuromuscular diseases. It is critical to differentiate whether the primary problem is weakness or spasticity, thus better understanding different phenotypes of spastic gait disorders. Pelvic girdle abnormality plays a pivotal role in determining the clinical presentation of gait disorders, since it determines the body vector and compensatory kinetic chain reactions in the knee and ankle joints. Knee joint abnormality can be a mechanical compensation …

Faculty, Staff and Student Publications

Respiratory infections in patients with cancer are common. A low threshold for bronchoscopy with bronchoalveolar lavage (BAL) should be maintained in immunocompromised patients with pulmonary opacities on chest imaging to evaluate for opportunistic infections. In those with unresolving symptoms, transbronchial biopsies may add significant diagnostic value. Concomitant hypercalcemia in patients with cancer is typically related to underlying malignant disease. However, in those with persistent respiratory symptoms or atypical infiltrates then granulomatous inflammatory diseases should be considered. Diagnosing histoplasmosis in immunocompromised patients can be difficult. Antigen testing is often more sensitive, but tissue biopsy or culture may be needed. We describe …
