Trial on the Efficiency of Topline® Against Natural Tick Infestations of Dromedaries in Mauritania

Topline®, as a 1% “pour-on” solution of fipronil, is produced by MERIAL Company. Fipronil is an acaricide used to control ticks and biting flies of cattle. Dromedaries are regularly infested by ticks. The effectiveness and residual activity of fipronil as a 1% w/w pour-on formulation (Topline®) was studied in a trial on ticks of calves of dromedaries near Nouakchott, Mauritania.

Superior Mesenteric Artery Embolus as a Delayed Complication of a Cocaine Induced Myocardial Infarction

Cocaine has acute and chronic effects on health as well as addiction and dependence and places a significant burden on healthcare systems. After cannabis, it is the most frequently used illicit drug worldwide. It is estimated that between 14 and 21 million people use the drug each year [1]. Its main adverse effects occur in the cardiovascular system. Cocaine causes sympathomimetic actions such as tachycardia, hypertension and coronary artery constriction due to enhancement of release of catecholamines. It enhances thrombus formation by activating platelets and potentiating thromboxane production [2]. The consequences of these effects include chest pain, myocardial infarction, aortic dissection, coronary artery aneurysm, myocarditis, cardiomyopathies and arrhythmias. Our case demonstrates a young patient who had a delayed presentation of a myocardial infarction, in the setting of recent cocaine use that was complicated by an apical thrombus which resulted in distal emboli to his superior mesenteric artery and left renal artery. It highlights the fact that in a young patient with no other risk factors how complications may arise, even weeks after cocaine use.
