Öğe Clinical and molecular study in a child with X-linked hypohidrotic ectodermal dysplasia(Soc Argentina Pediatria, 2015) Callea, Michele; Yavuz, Izzet; Clarich, Gabriella; Cammarata-Scalisi, FranciscoEctodermal dysplasia encompasses more than 200 clinically distinct entities, which affect at least two structures derived from the ectoderm, including the skin, hair, nails, teeth, sweat glands, and sebaceous glands. X-linked hypohidrotic ectodermal dysplasia is the most common type and is caused by mutation of the EDA gene that encodes Ectodysplasin-A. It occurs in less than 1 in 100 000 individuals and is clinically characterized by hypodontia, hypohidrosis, hypotrichosis, and eye disorders. We present a child evaluated in a multidisciplinary manner with clinical and molecular diagnosis of X-linked hypohidrotic ectodermal dysplasia with type missense mutation c.1133C>T; p.T378M in EDA gene.Öğe Ear nose throat manifestations in hypoidrotic ectodermal dysplasia(Elsevier Ireland Ltd, 2013) Callea, Michele; Teggi, Roberto; Yavuz, Izzet; Tadini, Gianluca; Priolo, Manuela; Crovella, Sergio; Clarich, GabriellaThe ectodermal dysplasias (EDs) are a large and complex group of inherited disorders. In various combinations, they all share anomalies in ectodermal derived structures: hair, teeth, nails and sweat gland function. Clinical overlap is present among EDs. Few causative genes have been identified, to date. Altered gene expression is not limited to the ectoderm but a concomitant effect on developing mesenchymal structures, with modification of ectodermal-mesenchymal signaling, takes place. The two major categories of ED include the hidrotic and hypohidrotic form, the latter more frequent; they differentiate each other for the presence or absence of sweat glands. We report Ear Nose Throat manifestations of ED, linked to the reduction of mucous glands in the nasal fossae with reduced ciliar function, and decrease salivary glands function. Often patients report an increased rate of infections of the upper respiratory tract and of the ear. Nasal obstruction due to the presence of nasal crusting, hearing loss and throat hoarseness are the most represented symptoms. Environmental measures, including a correct air temperature and humidification, is mandatory above all in subjects affected by hypohidrotic form. (C) 2013 Elsevier Ireland Ltd.

The evaluation of ectodermal dysplasia cases was made by clincal examination and examination of the jaw and facial areas radiologically and on cone-beam 3-dimensional dental tomography (CBCT) images. Material and Methods: In the 36 cases evaluated in the study, typical clinical findings of pure hypohidrotic ectodermal displasia (HED) were seen, such as missing teeth, dry skin, hair and nail disorders. CBCT images were obtained from 12 of the 36 cases, aged 1.5-45 years, and orthodontic analyses were made on these images. Results: The clinical and radiological evaluations determined, hypodontia or oligodontia, breathing problems, sweating problems, a history of fever, sparse hair, saddle nose, skin peeling, hypopigmentation, hyperpigmentation, finger and nail deformities, conical teeth anomalies, abnormal tooth root formation, tooth resorption in the root, gingivitis, history of epilepsy, absent lachrymal canals and vision problems in the cases which included to the study. Conclusions: Ectodermal dysplasia cases have a particular place in dentistry and require a professional, multi-disciplinary approach in respect of the chewing function, orthognathic problems, growth, oral and dental health. It has been understood that with data obtained from modern technologies such as three-dimensional dental tomography and the treatments applied, the quality of life of these cases can be improved.Öğe Oral manifestation of Goltz-Gorlin syndrome in a young girl(BioMed Central Ltd., 2012) Callea, M.; Yavuz, İzzet; Deroma, Laura; Montanari, Marco; Clarich, Gabriella; Maglione, Michele; Albertini, Enrico[No abstract available]
