1. Report Card on Humidity Control.

Author

Fischer, John C. and Bayer, Charlene

Abstract

Reports on an investigation of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standard 62-1999 on outdoor ventilation rates and space humidity levels for schools. Examined conventional cooling versus desiccant-based systems designed to control indoor humidity levels. Discusses the effectiveness of systems investigated, benefits offered by humidity control, and the need for increased ventilation. (EV)

Abstract

The angiographic findings in a patient with an interesting vascular tumor of the right atrium are described. The tumor was supplied by vessels from both the right and left coronary arteries and consisted of dilated blood spaces in which contrast material persisted for a prolonged period of time. Since this picture is identical to that described in cavernous hemangioma of other organs, this report presumably represents the first description of the angiographic findings in a cavernous hemangioma of the heart.

12. MIDDLE EAR INSUFFLATION

Author

GOLDSTEIN, CAPT ALLAN J. and FISCHER, JOHN C.

Abstract

To the Editor.—Recent reports from this laboratory have dealt with rupture of the tympanic membrane and death or serious complications in guinea pigs resulting from excessive air pressure within the middle ear space.1,2 In this animal it was not possible to demonstrate ventilation of the middle ear space by the eustachian tube. Recent work with the rhesus monkey has revealed that this is species dependent. All primate ears tested showed eustachian tube opening immediately upon rupture of the tympanic membrane. In one ear with serous otitis, there was eustachian tube dysfunction with step-wise reduction in pressure rather than immediate reduction. No death from overpressure resulted. We feel middle ear insufflation via eustachian tube catheterization is probably safer than via the external auditory canal. The basis for this is that in eustachian tube catheterization the tympanic membrane may act as a safety valve and rupture before pressure reached a
