Comparing Visual and Digital Counting Methods to Estimate Horn Fly (Diptera: Muscidae) Populations on Cattle.

Horn fly, Haematobia irritans (L.), population estimates often serve as a diagnostic tool prior to implementing managerial control options available to researchers and producers. Digital photographs taken of cattle infested with horn flies have been suggested to provide similarly accurate population estimates as compared with traditional visual assessments.

Coronary artery spasm and acute myocardial infarction in naproxen-associated anaphylactic reaction.

We present the case of a 43-year-old man who suffered an acute myocardial infarction after oral administration of 250 mg of naproxen, prescribed as antiinflammatory-analgesic agent after tooth extraction. Both intradermal skin test and human basophil degranulation test were positive to naproxen. These findings suggest a naproxen-associated anaphylactic reaction with concomitant coronary artery spasm and posteroinferior infarction, a clinical event previously not reported with the use of this drug.
