Delay in delivery of the Journal To the editor: On Jan. 21, 1977 I received two journals. One was the CMA Journal, published Jan. 8, 1977; the other was the New England Journal of Medicine, published Jan. 20, 1977. Why do I get a Canadian journal 2 weeks after publication and an American journal 1 day after publication? H.E. EMSON, MA, MD, FRcP[c] Department of pathology University Hospital Saskatoon, Sask.

[The answer to Dr. Emson's question is as follows: The Journal is mailed by third-class mail on the day of publication; NEJM is mailed by second-class mail - the newspaper rate - 1 week before the publication date. The Jan. 8, 1977 issue of the Journal was mailed to Dr. Emson from Montreal on Jan. 7, 1977 and took 2 weeks, which is reasonable for third-class delivery; the Jan. 20, 1977 issue of NEJM was mailed from Waseca, MN - relatively close to Canada - on Jan. 14, 1977 and took 1 week. The point made by Dr. Emson is a good one and the Journal would welcome information from readers concerning dates on which issues of the Journal are received. - Ed.]

one still has to add an increment required to accommodate an expanding population. The very evident shortages in some provinces must be considered as well. Dr. McKendry's statement in the last paragraph - to the effect that the disparity between my estimate and that of the original report relating to the needed number of ophthalmologists deserves prompt study - is very much to the point. The last sentence in his last paragraph shows how little he understands ophthalmology, the practice of ophthalmology, ophthalmologists and their capabilities. It is to be hoped more studies of this nature will serve to educate those who have influence in the decision-making that seems to be upon us. This much is owed the Canadian people. On the clearly hypothetical and invalid supposition that there may be an "ongoing overproduction" of ophthalmologists, Dr. McKendry outlines the difficulty of "retreading" ophthalmologists. What does he mean? Does he look upon the ophthalmologist as some sort of exclusive specialist, or technician, or possibly a form of optometrist with a courtesy medical degree? How uninformed can one be? We are basically physicians and surgeons with certain special technical skills, and no different from any other specialist.

Physician manpower requirements To the editor: May I reply to Dr. J.B.R. McKendry's comments (Can Med Assoc J 115: 983, 1976) relative to my criticism of the special report by Milan Korcok and D.A. Geekie on manpower requirements (Can Med Assoc J 115: 265, 1976)? In my original letter I said there are many imponderables in making medical manpower estimates. For instance, for some occult reason it is difficult to arrive at the exact number of practising ophthalmologists in Canada today; the number probably is at least 100 less than the figure of 780 given in the original article. (By ophthalmologists I do not mean physicians practising ophthalmology, but fully qualified ophthalmologists.) Included among the 780 mentioned in the report are some qualified ophthalmologists in administrative or semiadministrative positions, and some in semiretirement. The estimate of one ophthalmologist per 28 000 persons, as suggested by the committee report of the Council of Ontario Faculties of Medicine (COFM) (Boone report) had reference to full-time, fully qualified ophthalmologists. Dr. McKendry suggests that only 100 over and above the 780 will be required by 1981. On the above basis it is clear that a great many more than this, possibly twice as many, will be required, and

Found: alternative to the "Compendium of Pharmaceuticals and Specialties" (CPS) To the editor: After reading the letter by Dr. Warren Bell on the CPS (Can Med Assoc J 116: 349, 1977) I searched my cluttered desk to find an alternative to the CPS. I finally found one - The Medical Letter. According to Goodman and Gilman,1 "A very useful source of information on new drugs and therapeutics is the biweekly publication, The Medical Letter. Its distinguished board of editors provides a distinct service to medicine and to physicians by furnishing prompt, unbiased, pointed assessment of new drugs." The integrity of the Letter cannot be doubted. It is a nonprofit publication. Those familiar with the Letter may wonder how it is produced. Usually an expert in the field writes a draft. Then the draft is reviewed by the Letter's editors and advisers and by as many consultants as necessary, sometimes more than 30. When opinions differ, a consensus is arrived at. There are now laudable imitations of the Letter: Great Britain has the Drugs and

Therapeutics Bulletin and France, La Lettre Mt.dicale d'Information, for example, but none has such a well organized network of consultants. There are now two Canadian physicians on the advisory board. According to marketing departments in the drug industry, The Medical Letter is a nuisance. Yet there have been of late some "favourable" assessments of new drugs. For example, dopamine (Desberger's Intropin) was approved with little restriction and labelled "an important new drug" in the treatment of shock, having "the advantage over previously available catecholamines of a direct beneficial effect on renal blood flow".2 Who can ask for a better rating? The new nonsteroid anti-inflammatory drugs were labelled as "useful in treatment of rheumatoid arthritis" in the last September issue.3 The new antiseptic chlorhexidine (Hibitane-Ayerst) was also well rated last October.4 The scope of the Letter is no longer restricted to providing information just on drugs. There have recently been articles on colonoscopy, aortocoronary bypass, food additives, surgery for obesity, cardiac pacemakers, frostbite, surgery for colitis, influenza vaccination, water fluoridation, elastic stockings, high-fibre diet, ultrasound, radiographic therapy, mammography, cyclamates, allergy tests, poison ivy, intravenous fluid filters, intrauterine devices, pregnancy tests, treatment of hemorrhoids and mineral supplements. There is something for everyone. The Medical Letter covers areas of medical practice where decisions about whether to use a procedure are difficult to make. The Medical Letter on Medical Procedures might be a more appropriate name. New information on old and new drugs is now produced at such a rate that textbooks become obsolete, and the only alternative to reading the Letter would be to read all drug reviews appearing in the major medical journals. The Medical Letter requires 1 minute a day (15 minutes to read the few pages issued every other week). The presentation is tailored to the busy practitioner; it is usually limited to 4 pages, short paragraphs, concise sentences and few references. There is no equivalent in other areas of medical literature. A practitioner who does not have the time to read The Medical Letter does not have the time to read - in that case, may God help his patients.

Urticarial rash, periorbital edema following influenza (bivalent) vaccination To the editor: I report a case of urticanal rash and periorbital edema following influenza vaccination in a nonallergic young adult. A 23-year-old man, previously healthy, received 0.5 ml of bivalent influenza virus vaccine in each deltoid area on Oct. 26, 1976. The next day he noted puffiness around his eyes and a generalized itchy, red rash. The itching was relieved by the administration of oral and parenteral diphenhydramine hydrochloride (Benadryl). Because of persisting symptoms and signs he attended hospital on Dec. 6, 1976. He gave no history of allergies to egg, and no family history of allergic disorders. He was afebrile. Findings included urticarial lesions over the entire body, peniorbital edema, small, discrete lymph nodes in the cervical area, liver enlargement to 2 cm below the right costal margin and splenk enlargement to 2 cm below the left costal margin. Total leukocyte count was 5.6 x 10'! 1 (56% segmented forms and 33% lymphocytes); no eosinophils were seen. Results of blood chemistry studies, chest radiography and urinalysis were normal. VDRL testing and the differential slide test for infectious mononucleosis gave negative results. The patient was treated with hydroxyzine hydrochloride (Atarax) orally. The skin lesions and periorbital edema disappeared in about 7 days. Hepatosplenomegaly persists and follow-up is being continued in the outpatient clinic. U.
