[Influence of staining and mounting methods on Cryptomeria japonica and Cupressaceae pollen counts].

The staining and mounting method for measuring air-borne pollen differs at each institute resulting in discrepancies. We examined influence of staining and mounting methods on pollen counts of Cryptomeria japonica and Cupressaceae. Two Durham type pollen collection instruments, stored at the same place and holding slides coated with white vaseline, were exposed to the air for 24 hours.

New options for aerodigestive tract replacement after extended pharyngolaryngectomy.

Objectives: Assess the results of a new type of reconstruction of the aerodigestive tract after extended pharyngolaryngectomy.

Study Design: Follow-up of a total of eight patients who had surgery using ileocolic free graft.

Methods: The surgical technique is described.

Temporal lobe injury in temporal bone fractures.

Objective: To determine the incidence of intracranial injury, specifically in the temporal lobe, in patients with longitudinal fractures of the temporal bone.

Design: Prospective inception cohort.

Setting: University of Maryland Division of Otolaryngology-Head and Neck Surgery and the Maryland Shock Trauma Center, Baltimore.

Dose-dependent protection by azelastine eye drops against pollen-induced allergic conjunctivitis. A double-blind, placebo-controlled study.

The efficacy and tolerability of azelastine (CAS 58581-89-8) eye drops at three different doses (0.025%, 0.05% and 0.

Quantification of conjunctival vascular reaction by digital imaging.

Background: No objective evaluation of the conjunctival provocation test (CPT) was possible until now.

Objective: The aim of this study was to develop a tool that would enable us to monitor conjunctival allergic inflammation by objective measurements.

Methods: Twenty-four patients allergic to grass pollen were challenged by a CPT with grass pollen and genuine grass pollen in the "Vienna Challenge Chamber.

Differential integrin expression in thyroid and laryngeal carcinomas.

Several laryngeal and thyroid carcinomas were studied immunohistochemically to evaluate whether the expression and distribution of integrins and basal lamina components can represent reproducible markers for correct early diagnosis and prognosis. In laryngeal cancers, the depolarization and pericellular redistribution of alpha 3 beta 1 and alpha 6 beta 4, and focal or massive fragmentation of the basal lamina, according to tumor prognosis, occurred. In thyroid carcinomas, loss of polar topography of alpha 3 beta 1 and neo-expression of alpha 6 beta 4 in histopathologically or clinically aggressive cancers were observed.

Significance of adhesion molecules as biological prognostic factor in locally advanced laryngeal squamous cell carcinomas.

Thirty laryngeal carcinomas were studied immunohistochemically in order to evaluate whether the expression and different distribution of adhesion molecules influence the clinical features and progression of the tumors. On the basis of clinical and pathological variables, two different groups were established: one with good and the other with poor prognosis. The patients were included in one of the two groups on the basis of prognostic factors previously studied by multivariate analysis (the validity of this choice was confirmed by the NED survival curves of the two groups).

Investigation of long-term efficacy and tolerability of azelastine nasal spray in the treatment of perennial allergic rhinitis.
