RESUMEN
Cardiovascular diseases are recognised complications of pregnancy, however, pregnancy-associated acute myocardial infarction (PAMI) is uncommon. Pregnancy is known to increase risk of myocardial infarction even in the absence of traditional risk factors for atherosclerotic vascular disease. Our patient presented with acute chest pain two weeks after delivery and her electrocardiogram was in keeping with STelevation myocardial infarction (STEMI). Coronary angiography revealed coronary artery dissection and she was managed conservatively. Various pathophysiological mechanisms of PAMI have been described in literature including spontaneous coronary artery dissection (SCAD) found in our case. The diagnosis is often missed and earlier reported cases were diagnosed at autopsy. Therefore, we report this case as a learning tool. Also, there is a need for a high index of suspicion in pregnant patients presenting with features suggestive of aortic dissection, and its diagnosis should be thought of in peripartum women presenting with acute chest pain.
Les maladies cardiovasculaires sont des complications reconnues de la grossesse, cependant, l'infarctus aigu du myocarde associé à la grossesse (IPAM) est rare. La grossesse est connue pour augmenter le risque d'infarctus du myocarde même en l'absence de facteurs de risque traditionnels de maladie vasculaire athéroscléreuse. Notre patiente s'est présentée avec une douleur thoracique aiguë deux semaines après l'accouchement et son électrocardiogramme était conforme à l'infarctus du myocarde avec élévation de l'échelle (STEMI). La coronarographie a révélé une dissection de l'artère coronaire et elle a été gérée de manière conservatrice. Divers mécanismes physiopathologiques de PAMI ont été décrits dans la littérature, y compris la dissection spontanée des artères coronaires (SCAD) trouvée dans notre cas. Le diagnostic est souvent manqué et les cas signalés antérieurement ont été diagnostiqués à l'autopsie. Par conséquent, nous rapportons ce cas comme un outil d'apprentissage. En outre, il existe un besoin d'un indice de suspicion élevé chez les patientes enceintes présentant des caractéristiques suggérant une dissection aortique, et son diagnostic doit être envisagé chez les femmes en péripartum présentant une douleur thoracique aiguë.

A survey of gastrointestinal helminth parasites of stray dogs (Canis familiaris) was conducted at Obollo-Afor and Ekwulobia markets, in Enugu and Anambra States, south-eastern Nigeria, respectively, to determine the patterns of infection among dogs in different parts of south-eastern Nigeria. Faecal samples collected, using long forceps, from every dog encountered in the markets between June 2007 and December 2008 were analysed by the Kato-Katz technique. Out of 413 dogs examined in both markets, 217 (52.6%) were infected with at least one of five parasites (Toxocara spp., Dipylidium caninum, Ancylostoma caninum, Taenia spp. and Trichuris vulpis). Overall faecal egg intensity of infection was 49.9 ± 58.7 eggs/g (epg). The prevalence of infection was comparable between the markets and between the male and female dogs, but varied significantly (P < 0.05) by age, decreasing from 78.9% in pups to 36.0% in adult dogs. The mean intensity pattern was similar to that of prevalence, decreasing from 86.7 ± 63.0 epg in pups to 22.1 ± 34.4 in adults. The most important individual parasite infection was Ancylostoma spp. (39.2%; 30.0 ± 41.2 epg) while T. vulpis was the least important (1.9%; 0.7 ± 5.4 epg). Generally, prevalence and intensity patterns of each parasite were also comparable between the markets and between sexes, but significantly (P < 0.05) age-dependent. The implications of these findings to public health in Nigeria and other endemic countries are discussed in relation to options for cost-effective control design and implementation.
