R. S. Eliot; W. A. Millhon and J. Millhon. American Journal of Cardiology; 12; 767-771 (Dec. 1962). One hundred and ninety-five men with marked left axis deviation ( --30 to --90) ranging in age from 23 to 61 years were comparer! with 100 men with normal axis deviation in the same age distribution at an initial examination and at follow up 3 to 22 months later. Men with other ECG abnormalities, clinical cardiovascular-renal disease or dia betes mellitus known to exist prior to the initial examination were ex cluded from the study. 113 or 58% of the 195 subjects with LAD had cardiovascular disease or diabetes mellitus on the initial or follow up examination compared to 3% with hypertension and 1% with diabetes in the control group. A more detailed analysis of the abnormal findings revealed: Angina coronary insufficiency, myocardial infarction or a positive exercise tolerance test occurred or developed in 34% of the study group. None of these diagnoses occurred in those with NAD. Hypertension alone occurred in 14% of the LAD group compared to 3%. of the NAD group. 2% in the LAD group had both hypertension and angina. Subclinical or latent diabetes mellitus was found in 7% of the study group compared to 1% of the controls. Cerebral hemorrhage or infarction developed in 2% of the study group. Neither occurred in the controls. Six patients died of coronary or cerebrovascular disease in the study group during the brief period of follow up. Body habitus or blood cholesterol levels were not significantly dif ferent in the two groups. The group with LAD had a much stronger family history of cardio vascular disease than did the NAD group. The authors conclude that the ECG finding of uncomplicated marked LAD should be suspect because of the above associations.

R. Gallo and A. Glorig. Am. Ind. Hyg. Assn. ]. 25:237 (May- June 1964). ' With long-term exposures to industrial noise of 90 db octave band SPL, most hearing level changes at 3,000, 4,000, and 6,000 cps occur in the first 15 years, while at 500, 1,000, and 2,000 cps, bearing level change is linear with exposure time. Men have greater hearing level changes than women. Changes from noise and aging may not be differentiable. Asbestos Exposure During Naval Vessel Overhaul. VV. T. Marr. Am. Ind. Ihjg. A.swn. ]. 25:264 (Mav-June 1964). Exposures resulting in 6 eases of asbestosis among SO employees of a naval shipyard insulation shop were not picked up in time by X-rays since the cases took a minimum of seven years to develop. The maximum allowable concentration for short duration massive exposures is unknown, '['here is no agreement on the relative importance of short and long fiber asbestos. Shipboard pipe covering and insulation is hazardous and em ployees should wear respirators when exposed. Diffuse Mesothelioma and Exposure to Asbestos Dust in the Merseyside Area. W. G. Owen. Brit. Med. ]. 2:214 (July 25, 1964). Seventeen cases of diffuse mesothelioma were investigated and evidence was sought of exposure to asbestos dust. Clinical features of diffuse meso thelioma are discussed and the pathological findings in 12 cases are described. Exposure to asbestos was confirmed in 14 (82%) of the 17 cases examined, and asbestos bodies were found in 7 out erf 10 specimens of lung tissue examined. The author concludes that exposure to asbestos is a major factor in the cause of diffuse mesothelioma. The New Federal Clean Air Act. V. G. MacKenzie. Paper, Air Pollution Control Assn. 57th Ann.
