Pediculosis capitis is a common parasitic infestation, whereas phthiriasis palpebrarum is an uncommon infection due to Phthirus pubis (pubic lice) inoculating the eyelashes and surrounding tissues of the eye. Emergency physicians should recognize the causes of this uncommon disease. Cases of phthiriasis palpebrarum should trigger the clinician to consider the potential for child abuse when suspected or when social history dictates the risk for abuse. ⋯ Pediatric phthiriasis palpebrarum can represent child abuse, and the origins of this infection need to be carefully discerned. A thorough history can provide information to assess whether further action is needed and, if in doubt, social services should be contacted to ensure child safety.

Most out-of-hospital cardiac arrest (OHCA) studies have been conducted in developed countries or metropolitan areas, and few in developing countries or rural areas. ⋯ The survival rate of OHCA patients in nonmetropolitan Taiwan was very low (1.4%). Lower witnessed rate, lower bystander CPR rate, and longer response interval in remote areas are the main causes of inferior survival rate.
