Temporary threshold shift due to recreational firearm use.

OBJECTIVE: To assess whether a temporary threshold shift occurred after recreational firearm use. DESIGN: An observational study of 25 subjects using ear protection in an indoor rifle range. Hearing was evaluated before and after shooting five rounds with a 0.22 calibre rifle over 10 minutes. A threshold shift of 5 dB was found to be statistically significant, while a shift of 10 dB was clinically significant. RESULTS: Twenty-four candidates had a statistically significant threshold shift, while 12 had a clinically significant threshold shift. Two subjects with previous industrial noise exposure had threshold shifts at more frequencies than other subjects. There was no significant preference for either ear. One subject showed no changes. CONCLUSION: This small study sheds some light on impulse noise behaviour in an indoor shooting range, but no definite conclusions can be drawn. The side of shooting did not influence threshold changes in either ear.

Prevalence of hyperventilation syndrome in an allergy clinic, compared with a routine ENT clinic.

OBJECTIVES: A high prevalence of chronic hyperventilation syndrome in patients with asthma has been reported. We examined whether this phenomenon extended to allergy clinic patients in general and whether the prevalence was higher in patients attending a general allergy clinic compared with those attending a routine ENT clinic in our hospital. METHODS: We examined the prevalence of hyperventilation syndrome in unselected, consecutive patients (n = 100) seen in an allergy clinic. The validated Nijmegen questionnaire was completed by patients in the waiting room. We also administered the questionnaire to unselected, consecutive patients (n = 100) in a routine ENT clinic. RESULTS: There was no significant difference in prevalence of hyperventilation between allergy clinic and routine ENT clinic patients (25/100 vs 23/100). CONCLUSION: The result indicates a high prevalence of hyperventilation amongst hospital attendees in general. Consideration should perhaps be given to the possible role of hyperventilation in symptomatology.

Severe audiovestibular loss following ear syringing for wax removal.

Syringing of the ear is one of the commonest procedures performed for cleaning cerumen from the external auditory canal. Common complications following syringing are pain, external auditory canal trauma and otitis externa. Hearing and vestibular loss are often mentioned as a complication in descriptions of this technique, but we have not been able to find a reported case of such an occurrence. We report one such a case.
