Further Observations upon "Dermal Leishmanoid"

A vkry considerable number of cases of this condition are now referred to this department for diagnosis from Colonel Acton's skin outpatient clinic at the Calcutta School of Tropical Medicine since attention was first drawn to it, and at least two fresh cases are seen every week. In the early stage of the disease, when the lesions consist of white, non-pigmented tiny spots on the skin, it is ve...

Physiological observations during induced dyspnea.

DYSPNEA MAY be defined as a sense of need for increased breathing. As a symptom, it must be presumed to have a neurophysiological basis, including stimuli, receptors, and pathways of mediation. This report presents studies in which dyspnea was produced by exercise and added airway resistance iii normal individuals. These observations were concerned with the measurement of physiological paramete...

Physiological observations in Sydenham's chorea.

Involuntary movements in a patient with Sydenham's chorea were usually characterised by bursts of EMG activity lasting more than 100 ms, occurring asynchronously in antagonist muscles. The "hung-up" knee jerk was a choreic movement induced by the tendon tap. Exaggerated voluntary movements were produced with EMG burst longer than normal.
