We describe a 53-year-old women with eosinophilia-myalgia syndrome who suddenly developed severe persistent myalgias of her arms, legs, back, and shoulder after a 5-month period of daily L-tryptophan ingestion, associated with fever, progressive stenocardia and left-sided congestive heart failure. Laboratory tests showed a leukocytosis of 11.2/nl with 3.14/nl eosinophils and an elevated erythrocyte sedimentation rate. There was a marked, predominantly proximal sclerosis of her arms, legs and trunk with a brownish discoloration. The skin of her arms and legs appeared dimpled (peau d'orange). Findings of the electrophysiological examinations were consistent with sensory neuropathy and myositis. Remarkable fasciitis and interstitial myositis were present in a biopsy specimen (from skin to muscle) taken from her thigh. However, eosinophilic infiltrates were rare. Angiography revealed an apical obstructive cardiomyopathy. In this paper, we describe the clinical findings, the course over 2 years, as well as the therapeutic management. Furthermore, the most important differential diagnoses are discussed and the literature is reviewed with special attention given to more recent pathogenic insights into this newly recognized multisystem disease.

Eighty-eight patients undergoing percutaneous transluminal coronary angioplasty (PTCA) of 100 stenoses were studied for the presence of factors deemed significant in the etiology of silent myocardial ischemia. Thirty-two patients were asymptomatic during balloon dilations of 36 arteries, and 56 patients had angina during PTCA of 64 arteries. There were no differences in age, sex, prior anginal history, antianginal regimen, extent of coronary artery disease and number or duration of inflations between the 2 study groups. Previous infarction (33 vs 12%, p less than 0.02), Q waves in the target area (31 vs 7%, p less than 0.005) and diabetes mellitus (36 vs 17%, p less than 0.05) were present more often in the asymptomatic group. Sixty-four% of all asymptomatic patients had either diabetes or previous infarction in the target territory. Collateral circulation was more frequent in asymptomatic patients, probably reflecting the ability of collateral arteries to ameliorate ischemia. During 2-vessel PTCA, patients without angina during dilation of only 1 of the 2 treated arteries (discordant responders) had previous infarction in that artery's territory (5 of 5, 100%), whereas patients without previous infarction were either symptomatic or asymptomatic (concordant responders) during PTCA of both arteries. This study shows that asymptomatic ischemia occurs frequently during PTCA in patients with symptomatic coronary disease. Prior Q-wave infarction and diabetes mellitus are important, independent factors associated with painless ischemia. It is suggested that infarction produces a localized dysfunction of afferent cardiac pain fibers, whereas diabetes can cause a global cardiac sensory neuropathy.

This report describes the experimental design, methods, and baseline characteristics of patients enrolled in a Veterans Administration Cooperative Study on the effect of aspirin (325 mg t.i.d.) and dipyridamole (75 mg t.i.d.) (110 patients), or placebo (121 patients) on major vascular outcome variables in noninsulin-dependent diabetic patients with either a recent amputation for gangrene (n = 207) or active gangrene (n = 24). It also describes the baseline characteristics of the patients. A total of 231 patients of 563 screened (41%) were enrolled at 11 participating V.A. Medical Centers during a 39 month period. The median age at entry was 60 years, the median duration of diabetes was 10 years, and weight was 110% of desirable. All patients were men. Sixty-eight percent were treated with insulin and 32% with diet alone. Only 42% were smokers at entry, 40% had retinopathy, 61% sensory neuropathy, 42% hypertension, and 29% had a history of myocardial infarction, angina, and/or congestive heart failure. Thirteen percent had a history of cerebrovascular disease. Despite randomization, the treatment group had an increased frequency of a history of cerebrovascular disease (p = 0.01), diagnosed as stroke (p = 0.03), a finding suggesting that the treatment group was at a slightly increased risk for vascular disease upon enrollment in the study. Other baseline variables did not differ significantly between the two groups. This study should provide definitive data on the efficacy of these doses of antiplatelet agents in preventing further vascular disease in diabetic men with gangrene or recent amputation for gangrene, using death due to vascular disease and subsequent amputation of the opposite extremity for gangrene as major outcome variables. It should also give useful information on the effect of antiplatelet therapy on vascular outcome variables such as same side amputations, myocardial infarction, stroke, transient ischemic attack, retinopathy, and renal failure. Finally, the study should provide useful data on the natural history and significance of risk factors in this patient population.
