Fifteen reasons are given why occupational medicine should he taught. Among them are the needs for: a g reater knowledge of occupational health problem s; correction of erroneous concepts held by students; p ro v isio n of b e tte r m edical s e rv ic e to industry; a m o re ....... skilled assum ption of m edicolegal responsibilities; furthering both a holistic and a preventive approach to medicine; and the creation of a research sen-ice for industry. Other questions discussed w ere: what subjects should be caught, who does the teaching, and w here the teach lag should be accom plished, and in what year o r years the instruction should be given. A number of valuable suggestions a re given under each of these headings. i <9 Scientific M edicolegal Investigation in the Unde: graduate M edical Cur ricuium. a. M oritz. J . A m . bled.

I* L. W hittenberger. New Engl. J . M ed. 51, 816-620 (Nov., 11, 1954). The subject of artificial respiration, both in resuscitation and in therapy is review ed, with em phasis on principles rath e r than on p a r. ticular m ethods. Subjects that have received little study include alveo la r ventilation ra te s, ventilation distribution, diffusion capacity, and ventilation-perfusion relations. The lim its of safe p re s su re levels in the lungs a re not p recisely known. F o r se v e ra l reaso n s inflation of the lungs is difficult, and in all form s of external resp iratio n , an effective in sp irato ry phase appears to be of prim e im portance. V arious methods of m an u al and m echanical re s p ira tio n a re d isc u sse d with re g a rd to th e ir efficiency. The circulatory effects of artificia l resp iratio n encompass a spectrum from the circulation-prom oting action of natural respiration to the potentially s e v e re im p airm en t that m ay be due to n fluctuating p o s itiv e-p ressu re device, la the norm al patient the effects on respiration are tem porary, but in the im paired patient, deleterious consequences can be m inim ised by general supportive m easu res and reduction of the m ean m ask p ressu re. The success of any method of artificial re sp ira tion is favored by knowledge of the underlying physiologic m echanism s and th eir interactions with the methods' used. - - Cond. from author's sum m ary (Arch.
