Healthy ear canal skin has an acidic pH. Evidence suggests that reacidification of the ear canal may lead to resolution of otitis externa. The pH of 15 commonly prescribed topical ear drop preparations used in the treatment of otitis externa was measured using a Jenway 3020 pH meter with temperature compensation at 37.5°C. The pH values ranged from 2.89 to 7.83. Two-thirds of preparations tested were of acidic pH. The remaining one-third were alkaline. Reacidification of the ear canal may help in the treatment of otitis externa. [ABSTRACT FROM AUTHOR]

We describe an unusual case of recurrent, refractory anterior epistaxis in ah 86-year-old man with two mechanical heart valves who was on permanent warfarin therapy. His numerous episodes of epistaxis were incited by chronic nose-picking and strong nose-blowing, practices that he continued to engage in despite repeated medical advice to stop. Stopping his anticoagulation therapy was not considered as a management option because of an unacceptably high risk that this would lead to a thromboembolic event. Eventually, we temporarily sutured his nares closed, and his nosebleeds ceased. The suturing was performed in the ward with local anesthesia. This procedure was simple to perform, fairly well tolerated, easily reversible, and highly effective. [ABSTRACT FROM AUTHOR]
