Emerging and re-emerging infectious disease in otorhinolaryngology.

Emerging and re-emerging infectious disease in otorhinolaryngology (ENT) are an area of growing epidemiological and clinical interest. The aim of this section is to comprehensively report on the epidemiology of key infectious disease in otorhinolaryngology, reporting on their burden at the national and international level, expanding of the need of promoting and implementing preventive interventions, and the rationale of applying evidence-based, effective and cost- effective diagnostic, curative and preventive approaches. In particular, we focus on i) ENT viral infections (HIV, Epstein-Barr virus, Human Papilloma virus), retrieving the available evidence on their oncogenic potential; ii) typical and atypical mycobacteria infections; iii) non-specific granulomatous lymphadenopathy; iv) emerging paediatric ENT infectious diseases and the prevention of their complications; v) the growing burden of antimicrobial resistance in ENT and the strategies for its control in different clinical settings.

TTF-2/FOXE1 gene polymorphisms in Sicilian patients with permanent primary congenital hypothyroidism.

Thyroid transcription factor-2 (TTF-2/FOXE1) is a polyalanine domain protein that regulates thyroid embryogenesis, but very few patients with permanent primary congenital hypothyroidism (pCH) harbor germline mutations of this or other transcription factors that are involved in thyroid development that might explain the etiology of pCH. Variations within the polyalanine tract are found in a variety of genes and are often reported in association with malformation syndromes; pCH is frequently associated with thyroid malformations and extra-thyroidal malformations. Therefore, in this study we investigated whether alanine (Ala) length polymorphisms and non-polymorphic mutations of the TTF-2 gene in pCH patients might be involved in the pathogenesis of pCH.

Vestibular disorders in primary thrombocytosis.

Objective: Balance disturbances are some of the most common symptoms among the clinical manifestations of chronic myeloproliferative disorders (MPDs) with a high platelet count, such as essential thrombocythaemia (ET) and polycythaemia vera (PV). In this study, we evaluated the vestibulo-oculomotor and vestibulospinal reflexes in a group of patients suffering from these diseases.

Design: Evaluation of balance disturbances.

Electrophoretic pattern of physiological human nasal secretions.

Various proteins have been detected in human nasal mucus, but their electrophoretic pattern has not been extensively investigated. Therefore, we have studied this pattern in nasal mucus samples from a group of 40 healthy subjects (20 males and 20 females). The electrophoretic separations have been performed under both native and denaturing conditions.

[Delayed endolymphatic hydrops: an analysis of 12 cases].

Delayed Endolymphatic Hydrops (DEH) is a clinical entity which is characterized by an early phase with a profound sensorineural hearing loss in one ear. After a prolonged period of time (from 1 to 68 years) a late phase of the disease appears with different otologic symptoms. The ipsilateral type of endolymphatic hydrops appears in the deaf ear with consequent episodic vertigo.
