Iatrogenic postoperative left ventricular outflow tract obstruction

A 56-year-old female, who underwent aortocoronary bypass graft for occlusion of anterior descending artery is reported, who postoperatively developed a harsh systolic murmur, mitral regurgitation, and intraventricular systolic pressure gradient suggestive of hypertrophic subaortic stenosis. The above findings were due to the administration of dobutamine hydrochloride for hypotension in association with afterload reduction (intra-aortic balloon pumping) and disappeared almost immediately after left ventriculography (volume load).     

Haemophilus Influenzae Septic Thrombophlebitis Following Use of a ��Scalp-Vein�� Needle

Indolent Haemophilus influenzae type B septic thrombophlebitis developed in a 14-year-old boy two weeks after completing a course of intravenous antibiotics administered via a “scalp-vein” needle for an unrelated infection. Presumably, the primary disease (common variable immunodeficiency) contributed to the simultaneous occurrence of this uncommon complication of scalp-vein needle use, with an unusual pathogen.
