Does soccer ball heading cause retinal bleeding?

OBJECTIVES: To define forces of youth soccer ball heading (headers) and determine whether heading causes retinal hemorrhage. SETTING: Regional Children's Hospital, youth soccer camp. PATIENTS: Male and female soccer players, 13 to 16 years old, who regularly head soccer balls. MEASUREMENTS: Dilated retinal examination, after 2-week header diary, and accelerometer measurement of heading a lofted soccer ball. RESULTS: Twenty-one youth soccer players, averaging 79 headers in the prior 2 weeks, and 3 players who did not submit header diaries lacked retinal hemorrhage. Thirty control subjects also lacked retinal hemorrhage. Seven subjects heading the ball experienced linear cranial accelerations of 3.7 +/- 1.3g. Rotational accelerations were negligible. CONCLUSIONS: Headers, not associated with globe impact, are unlikely to cause retinal hemorrhage. Correctly executed headers did not cause significant rotational acceleration of the head, but incorrectly executed headers might.

Asthma, allergy, and sinopulmonary disease in pediatric condition falsification.

Reports of pediatric condition falsification (PCF) have noted, but not emphasized, exaggerated complaints of real and common illnesses. Among the most frequent chronic childhood illnesses are asthma, allergy, drug sensitivity, and ear and sinopulmonary infections. The most common pediatric surgery is the insertion of myringotomy tubes. A computer database of 104 PCF victims from 68 families spanning from 1974 to 1998 was searched for the frequency of these conditions. Outright falsification or extreme exaggeration of severity of asthma or allergies was noted in 52 children (50%), sinopulmonary infections in 50 (48%), and drug reactions or sensitivities in 30 (29%). Forty-five children (43%) had otolaryngologic surgery, including ear tubes. In all, 71 children (68%) had at least one of these conditions. Associated victim and perpetrator characteristics are described. Children with PCF are not only subjected to induced illnesses and excessive medical diagnostic and therapeutic efforts but also victimized b) the consequences of false and exaggerated complaints of common pediatric diseases.
