Remedies for headache prescribed by doctors have all passed the test of a placebo trial, carried out in the relatively calm atmosphere of university hospital out-patient departments. The trial reported here was done in a much more unusual setting in 1995 by a group of doctors and scientists from the US National Institutes of Health in Bethesda, Maryland. All of us have had headaches, with which we coped as well as we could. This trial was carried out on 30 patients whose headache disturbed them so much that they had gone to a hospital emergency department. It is important to realize that these patients would have been unusually worried by their headache and would have been full of expectation that powerful medicine would be given. Everyone was given an injection: one-third were given an aspirin-like drug, ketoralac, one-third a narcotic, meperidine, and the other third received a saline injection, all double-blind. All three injections produced an identical reduction of pain. The reason for choosing this example of a placebo effect is to emphasize the effect of the patients’ expectation in exaggerating the placebo effect. The two drugs had normally been tested on relaxed patients and shown to be superior to placebos. In this case, where the patients had deliberately sought emergency treatment and had a high expectation, the placebo was as effective as the drugs. Clearly, we are dealing with a subtle but powerful effect.

On the other hand, women grow up unashamed of fears, or tears, or weakness ; unused to roughing it; unaccustomed to fighting except with an unrestrained tongue; untrained to suffer the consequences for abusive words; spoiled by chivalry with its special privileges for their sex; willing to gain ends in ways that would be embarrassing to a man; discouraged from playing with mechanical toys in childhood; not expected to be rational; feeling no disgrace in dependence, often never knowing what the full weight of economic worry is; generally seeing no goal except the primitive task of keeping house and escaping boredom by belonging to card clubs; and in matters of sex taught that it is unladylike to enter into such experiences except reluctantly.2
How can we expect a man and woman to be companions to one another when they have had such divergent training? How can a man be educated to despise cowardice and poor sportsmanship and not feel contempt for his wife in so far as she has these traits? And how can a woman avoid feeling that her husband is unreasonable and selfish in wanting to put on his old clothes and go on a fishing trip when she wants to make an impression at a fashionable resort? These irritations, however, that arise out of the commonplace affairs of life, cannot leave the romantic feelings unaffected. Romance cannot long survive between two people who have little common ground of fellowship. Yet most people see no contradiction in their defence of the traditional differentiation of the sexes on the one hand, and their expecting sublime companionship between a man and his wife, on the other.

Oral hairy leukoplakia is an infection of the mouth which resembles thrush. Its cause is unknown, but it appears to be associated with the virus that causes infectious mononucleosis. Most infections by the infectious mononucleosis virus produce only trivial symptoms or no symptoms, but once the infection with mononucleosis virus occurs, the virus remains in the mouth for the duration of life. The person with oral hairy leukoplakia does not have the usual symptoms of infectious mononucleosis and does not transmit infectious mononucleosis to others. Oral hairy leukoplakia appears to be an unusual reaction to the common presence of this virus in the mouth.
As noted earlier, most of the conditions that occur in people with HIV infections also occur in the rest of the population. Oral hairy leukoplakia appears to be an exception: it occurs exclusively in people with HIV infection.
Unless the person is in pain, treatment is not warranted. Oral hairy leukoplakia does seem to indicate that the immune system is increasingly suppressed, and that the development of AIDS is probable within the next few years.
