Long-term prognosis of women with Brugada syndrome and electrophysiological study.

Background: A male predominance in Brugada syndrome (BrS) has been widely reported, but scarce information on female patients with BrS is available.

Objective: The purpose of this study was to investigate the clinical characteristics and long-term prognosis of women with BrS.

Methods: A multicenter retrospective study of patients diagnosed with BrS and previous electrophysiological study (EPS) was performed.

Magnetic resonance imaging of the pharynx in OSA patients and healthy subjects.

Obstructive sleep apnoea (OSA) occurs because of recurrent narrowing and occlusion of the velopharynx (VP) during sleep. The specific cause of OSA is unknown. Cephalometric radiography, fibreoptic nasopharyngoscopy, acoustic reflection techniques, and computerized tomography have limitations (dynamic and tridimensional evaluation) in the mechanism of occlusion investigation.

Young's syndrome: a further cause of chronic rhinosinusitis.

Three males--aged 32, 35, and 27 years--presented Young's syndrome: a combination of obstructive azoospermia and chronic sinopulmonary infection. The evaluation of nasal mucociliary transport using an isotopic technique revealed mucociliary stasis in one case and decreased clearance in the others (< 2 mm/min). Ciliary ultrastructure was normal in two patients, while the other showed mucous hyperplasia and low ciliary density which made correct ciliary evaluation not possible.

[The prevalence of primary dyskinetic ciliary syndromes in patients with sinusitis and bronchiectasis].

In this paper are studied the prevalence of this syndrome (the PDCS) in 18 patients affected either of chronic sinusitis or bronchiectasias. Fourteen cases (77%) fulfil the diagnostic requirements in order to be considered as PCDS. Clinical differential features with regard to the idiopathic group are: situs inversus, male's infertility, perennial rhinorrhea and secretory otitis media.

Immotile cilia syndrome: nasal mucociliary function and nasal ciliary abnormalities.

We present 17 patients with a typical symptomatology of immotile cilia syndrome, seven of them with complete situs inversus. Firstly, a study of the nasal mucociliary transport was made by means of the radioisotopic technique with serum albumin-Tc99m. In all cases there was absence of transport.
