RESUMEN
INTRODUCTION: Most studies on nematode-malaria interactions were conducted outside of the Americas. The objective of the present study was thus to study the relation between malaria and nematodes in a cohort of children in an Amazonian village. METHODS: Odds ratios for intestinal nematode infections as an explanatory variable to malaria resistant vs. malaria sensitive were computed. RESULTS: Ascaris lumbricoides was significantly more frequent in the 'resistant' malaria group than in the 'sensitive' one. CONCLUSIONS: Despite its low statistical power, the present results find that Ascaris was associated with less malaria, as observed by a number of studies.

The authors report the case of a 33 year old man with distal occlusive arterial disease diagnosed as Buerger's disease, with two previous transient ischaemic attacks and coronary disease resulting in myocardial infarction. Coronary angiography showed narrowing of the second segment of the left anterior descending artery, occluded distally and not suitable for revascularisation. The observation of coronary artery disease is very rare in Buerger's disease and data of coronary angiography are very sparse in this context. The occurrence of myocardial infarction and the angiographic appearances of the left anterior descending artery raise the question of coronary involvement of Buerger's disease.
