Seabather's Eruption

Proceedings of the Physiological Society

“…36 P SOCIETY, 14 JANUARY 1956 of the centres upon which these impulses impinge. Certainly, evidence does exist that pulsatile pressures are more effective in eliciting barosensory reflexes than non-pulsatile pressures of the same mean value (McCrea & Wiggers, 1933;Strauss, 1940). Recently Ead, Green & Neil (1952) found that on conversion of a steady flow through the sinus region to a pulsatile flow, blood pressure fell and the previous continuous discharge in monitored sinus nerve fibres changed into bursts of impulses at a higher frequency: the total number of impulses occurring in a given time sometimes remained unchanged.…”

Marine Dermatosis

“…based his opinion on the facts that (1) a dermatitis was produced in human subjects exposed to Schistosoma cercariae from Haminoea an¬ tillarum quadalupensis; (2) the lesions produced experimentally appeared to be identical with those reported for "seabather's eruption" and "swimmer's itch"; (3) the duration of the experimental dermatitis was similar to that reported for "seabather's eruption"; (4) a second species of schistosome cercariae was isolated from Nassarius vibex Say, and, (5) N. vibex is one of the more common snails inhabiting the sandy beaches of Florida and therefore suspected as a possible reservoir for dermatitis-pro¬ ducing cercariae. Strauss ( 1956) reported approximately 75 persons suffering with "seabather's erup¬ tion" following exposure in the Guantanamo Bay area on the southeastern shore of Cuba during April and May, 1954. Pastrana (1941) and Moschella (1951) previously recorded cases of seabather's eruption from this same area.…”
