Prevention of rheumatic recurrence in the allergic, rheumatic fever patient To the Editor: Drs. Ginsburg and Eichenwald 1 appear to recommend erythromycin for streptococcal prophylaxis in penicillin-allergic rheumatic fever patients to prevent recurrences. They cite two small efficacy studies which lack comparative treatment groups. ~, ~ I think that they should have advocated sulfonamides, rather than erythromycin, as the preferred alternative to penicillin. Sulfadiazine has been rigorously tested in rheumatic fever patients and found to be as effective as oral penicillin in preventing streptococcal infections and rheumatic recurrences? Both oral regimens, however, are less effective than intramuscular benzathine penicillin because of poorer compliance. The American Heart Association recommendations on prevention of recurrent attacks of rheumatic fever reserve erythromycin for "the exceptional patient who may be sensitive to both penicillin and sulfonamides" and as a substitute for sulfonamides in penicillin-allergic women during late pregnancy? .~ Sulfonamides pass the placental barrier readily, compete with bilirubin for albumin-binding sites in the neonate, and may potentiate kernicterus. Although sulfonamides are effective for prophylaxis, they should not be used for treatment of streptococcal pharyngitis; they do not eradicate established streptococcal infection, and do not prevent rheumatic fever/ As noted by Drs. Ginsburg and Eichenwald, 1 erythromycin is appropriate treatment for penicillin-allergic patients with pharyngitis, since it eradicates streptococci and, by extrapolation, should prevent rheumatic fever.

Reply To the Editor: We thank Dr. Lerman for his comments. We are aware of the various recommendations for prevention of recurrent attacks o f rheumatic fever and agree that sulfonamides are suitable alternatives for the penicillin-allergic patient. It was not our intent to compare the efficacy of t h e various prophylactic regimens for rheumatic fever and as such we were not making specific recommendations in this regard. Charles M.

Oxandrolone therapy for children with Turner syndrome To the Editor: Moore and associates ~ have shown that the anabolic steroid, oxandrolone, significantly increases growth velocity in patients with Turner syndrome during the first year of therapy. This increase in growth velocity was not demonstrated in the subsequent years of treatment, andl indeed, there was deceleration in many cases. This group of workers went on to conclude that longterm oxandrolone treatment improved ultimate height. Their evidence for this deduction was more tenuous: it was based on
