A INDUSTRIAL MEDICAL PRACTICE Effect of Smoking on Asthma and Emphysema. G. A. Peiurs and R. Drew Miller* Proc. Staff Meetings Mayo Clinic 35, 353-358 (June 22, I960). Clinical observations, studies in laboratory animals and objective measurements j( pulmonary function in smokers and non-smokers indicate that bronchial secretions and ciliary action as well as bronchial muscular tone may be unfavorably altered by cigarette smoke, so that impairment of pulmonary function may occur* The authors have described representative cases in which objective improvement of pulmonary function in asthma and mphy6cmu followed cessation uf smoking* Although the exact etiologic relationship of amoking to emphysema is not as yet dear, it is apparent ^hat patients with asthma, bron chitis or emphysema should not smoke. Failure to advise such patients to stop smoking tonititutes incomplete therapy. - Authors' summary Tobacco Amblyopia. C. W. Rucker. Proc* Staff Meetings Mayo Clinic 35* 3*15-3*18 (Juno 22, I960). Excessive smoking of tobacco causes dimuess of vision In some persons. The nature of the visual loss is so characteristic that a careful examiner can usually bo certain thu diagnosis even in the absence oi supporting information. Although It impairs ability '< read and to recognise faces, it does not lead to blindness. The exact means by which udwcco impairs vision Is not known* A plausible suggestion is that it has a toxic action on T:.lnouri*hed cells in tho retina. Nicotine is not alone responsible for the deleterious affects -n vijion* Other volatile alkaloids present in the tobacco or formed during its combustion !>.; produce poisonous effects* The general health and nutritional state of the patient are .-tirmlning factors. The majority of patients are elderly, or at least past the age of 50. disproportionately large number have diabetes, which perhaps lowers thoir resistance. -r.y uf those who smoke excessively also drink excessively, and this has posed the question ;*u relative importance of alcohol in this disorder. There is so much overlapping that it h Seen given the name "tobacco-alcohol-amblyopia". Treatment consists o( abstinence .?.i tobacco and an adequate, balanced diet with supplements of vitamin B complex. If the :-.l loss Is of only a few months' duration and If thsro is no atrophy of the optic nerve se 'Jiinced by pallor of the optic nerve heads, some restoration of vision is to be expected. ' n rocess is slow and may continue over s period of several months to a year. Optic -*:..t,hy precludes much return to vision. f r.; logical Effects of SmoklnB'oinKn~Larynx and Oral Cavity. X. D.
