Validation of mandibular movements' analysis to measure sleep in adults with sleep complaints by comparison with actigraphy and polysomnography.

Objective: In adults with sleep complaints, we assessed the software of automatic analysis of mandibular movements to identify sleep and wake states by confrontation with the polysomnography (PSG) and the actigraphy (ACTG).

Material And Methods: Simultaneous and synchronized in-lab PSG, ACTG, and JAWAC were carried out in 100 patients with a sleep complaint. Epoch by epoch analysis was realized to assess the ability to sleep-wake distinction.

Benzofuran-derived benzylpyridinium bromides as potent acetylcholinesterase inhibitors.

A series of benzofuran-based N-benzylpyridinium derivatives 5a-o were designed and synthesized as novel AChE inhibitors. The synthetic pathway of the compounds involved the preparation of 4-(benzofuran-2-yl)pyridine intermediates via the reaction of different salicylaldehyde derivatives and 4-(bromomethyl)pyridine, followed by intramolecular cyclization. Subsequently, the 4-(benzofuran-2-yl)pyridines were N-benzylated by using appropriate benzyl bromide to afford the final product 5a-o.

Tracheobronchial foreign bodies: presentation and management in children and adults.

Study Objectives: To compare the clinical and management aspects of tracheobronchial aspirated foreign body (AFB) removal in children and adults; to assess the influence of the operator's experience on the outcome of the procedure.

Design: A retrospective review of a 20-year experience (from 1976 to 1996).

Setting: A 900-bed university hospital.

Rupture of aortic aneurysm with right-sided haemothorax.

A 62-yr-old male with a history of high blood pressure was admitted for persistent dyspnoea and a right-sided pleural effusion, complicated by a recent episode of shock. There was no history of trauma and the patient denied any thoracic pain. A chest tube was inserted which released nonclotting bloody fluid.

Nonfibrous mineralogical analysis of bronchoalveolar lavage fluid from blast-furnace workers.

Steelworkers are exposed to many pollutants, and they are at risk for developing lung cancer. We demonstrated previously that steelworkers may be subject to an occult exposure to amphiboles in the plant environment. In the current study, we further analyzed bronchoalveolar lavage fluid of steelworkers by measuring intramacrophagic trace-metal content and nonfibrous mineral particles, using the particle-induced x-ray emission method and electron microscopy, respectively.

A case of tracheal fibrolipoma.

We report the case of a tracheal fibrolipoma in a 40-year-old man successfully treated by laser photocoagulation. The clinical and pathological aspects, as well as the therapeutical options of this rare upper airway benign tumor are discussed.
