The possible cochlear toxicity of systemically applied macrolides--erythromycin (ER), azithromycin (AZ) and clarithromycin(CL)--was investigated in guinea pigs by measuring transiently evoked otoacoustic emissions (TEOAEs). A single dose of 125 mg/kg intravenous (i.v.) ER caused no change in TEOAEs in guinea pigs (p>0.05), whereas AZ (45 mg/kg orally) and CL (75 mg/kg i.v.) reversibly reduced the emission response (p<0.05). ⋯ The present study reveals that at least one ototoxic effect of AZ and CL is on the inner ear. The results may also encourage planning clinical researches on TEOAE monitoring in patients receiving high doses of AZ or CL.

Topical vasoconstriction using four to 10 per cent cocaine is widely used for nasal surgery. A number of techniques are being used with equally satisfactory results. Here we describe a novel method of topical application of cocaine for nasal surgery. The method is simple, cheap and effective.

A case of an isolated hypoglossal nerve palsy is reported. The differential diagnosis is discussed, in the context of the requirement for careful scrutiny of the entire course of the hypoglossal nerve on imaging, to detect underlying pathology remote from the tongue, and to avoid unnecessary invasive diagnostic procedures prompted by the appearance of a 'pseudomass' of the weak tongue both clinically and radiologically.

Behçet's disease is a rare condition in children and characterized by a triad of recurrent aphthous stomatitis, genital ulceration and uveitis. The aetiology is unknown, but systemic vasculitis is the main pathology. ⋯ We presented a 12-year-old girl with the initial complaint of recurrent aphthous stomatitis. During the follow-up period, we observed the other cardinal signs of the Behçet's disease.

Nasal endoscopy is a valuable adjunct to the localization of the sphenopalatine ganglion. Twenty-two patients with advanced malignancies of the head and neck region whose pain was not adequately controlled with conventional medications, including oral morphine, were given nasal endoscopically guided neurolytic sphenopalatine ganglion block with six per cent phenol after a prognostic block with local anaesthetic solution. Seventeen patients had good immediate relief. ⋯ On follow-up for one month, the patients had significantly lower pain intensity and the pain was more manageable with oral medication. The vicious cycle of pain was broken. This block is relatively safe and can be usefully performed as an out-patient procedure.
