ABSTRACT
BACKGROUND: This study was designed to compare the efficacy and tolerability of a new topical (nasal spray and eye drops) H1-receptor antagonist, levocabastine, with that of orally administered terfenadine for the prophylaxis and treatment of seasonal allergic rhinoconjunctivitis. METHODS: A total of 115 patients with documented birch pollen allergy were enrolled in this randomized, double-blind, double-dummy, parallel-group trial. Treatment was initiated immediately before the birch pollen season started and continued for a total of 8 weeks. Xylometrazoline (Otrivin) nasal spray was permitted as rescue medication. RESULTS: The investigator's evaluation of symptoms showed similar effects for levocabastine and terfenadine. Both the patients' and the investigator's global evaluations of ocular and nasal symptoms disclosed a somewhat higher percentage of good or excellent results for levocabastine, but the differences were not statistically significant. Visual analog scale ratings from the patients' diaries showed better results for levocabastine. Levocabastine was significantly more effective than terfenadine in relieving sneezing, rhinorrhea, lacrimation, itch, and burning sensation (p < 0.05). For some symptoms, levocabastine was significantly more effective than terfenadine on days when the pollen count was high. There were no statistically significant differences in the use of rescue medication or in the incidence of adverse reactions reported in each treatment group. CONCLUSIONS: In the present study topical levocabastine was frequently more effective than orally administered terfenadine for the treatment of seasonal allergic rhinoconjunctivitis. Both drugs were well-tolerated.

The youngest reported case of laryngeal granular cell tumor is presented together with transmission electron micrographs of the tumor cells. Whereas subglottic involvement is unusual in adults, a review of the literature reveals that three of the seven youngest patients (including the present patient) with laryngeal granular cell lesions had a subglottic tumor immediately below the anterior commissure.

The causes of unilateral orbital disease encountered during a seven year period are reviewed. Although orbital involvement secondary to primary rhinological conditions accounted for 73 per cent of the cases, the importance of systemic disease, and in particular angiitis, as a cause of orbital pseudotumor is stressed.
