In order to learn more about stretch reflex behaviour of triceps surae, normal human subjects sat in a chair with one foot on a platform attached to a torque motor that produced phasic dorsiflexion displacements on the ankle. EMG activity was recorded from triceps surae and responses were obtained for various conditions. When the subjects's foot was(More)
Electromyographic responses of triceps surae to dorsiflexion stretch were studied in 47 patients with a variety of lesions producing an upper motor neuron syndrome. The short latency spinal reflexes, both when the patient was at rest and when he was exerting a voluntary plantarflexion, were frequently enhanced in magnitude and the rate of increase with(More)
We reviewed autopsies of neonates who had died of meningitis. Plexitis and ventricular exudate were usually present. While the pathogenetic relationship between these two phenomena is uncertain, it is possible that the glycogen-rich choroid plexus of the lateral ventricles not only facilitates local bacterial growth but also acts as a bacterial reservoir(More)
A child with idiopathic myeloid metaplasia is described and her course contrasted with another child having myeloid metaplasia secondary to reticulum cell sarcoma. Despite prior reports the idiopathic form of illness may pursue a relatively indolent course in children. A thorough search should be made for underlying disease when myeloid metaplasia is first(More)
The authors report the case of a child with retroperitoneal ganglioneuroma and cytodifferentiated skeletal metastases. The primary tumor was surgically resected, and the child is alive and well 2 years later without additional therapy. This rarely documented phenomenon can be explained by spontaneous cytomaturation within both primary and metastatic tumor.
HLA-A,B and DR antigens were evaluated in 51 patients with mucocutaneous lymph node syndrome (Kawasaki disease) during both endemic and epidemic periods in the Boston area. Although 80% of patients were HLA-B5 (70% HLA-Bw51) during endemic periods, there were no HLA-B5 individuals during the epidemic period. There was, however, an increased incidence of(More)
We outline the implementation of a new method of measuring the quality of medical care that counts cases of unnecessary disease and disability and unnecessary untimely deaths. First of all, conditions are listed in which the occurrence of a single case of disease or disability or a single untimely death would justify asking, "Why did it happen?" Secondly,(More)
