Cervical dentine hypersensitivity is the most frequent complaint among reported odontalgias. Thus, this study evaluated the effectiveness of two types of lasers (660 nm wavelength red, and 830 nm wavelength infrared) as dentine desensitizers, as well as both the immediate and late therapeutic effects in individuals 25 to 45 years of age. A total of 40 teeth with cervical exposure were treated in 4 sessions. They were divided into 2 groups according to treatment. A 660 nm wavelength red diode laser and an 830 nm wavelength infrared diode laser were used. Dentine sensitivity to cold nociceptive stimulus was evaluated by means of a pain numeric scale from zero to 10 before each treatment session, at 15 and 30 min after irradiation, and in a follow-up period of 15, 30 and 60 days after the end of treatment. Significant levels of dentinal desensitization were only found in patients ranging in age from 25 to 35 years. The 660 nm red diode laser was more effective than the 830 nm infrared laser and a higher level of desensitization was observed at the 15 and 30 minute post-irradiation examinations. The immediate and late therapeutic effects of the 660 nm red diode laser were more evident in 25-35-year-old patients compared with those of the 830 nm infrared diode laser, in terms of the different age groups.

Microarrays permitted us definition of the gene expression profile of the lesion and identify an increased Th1 activity in RAU lesions.

An intense inflammatory infiltrate in AC was predictive of an adjacent invasive SCC. In this study, the p53 protein immunoreactivity was not a marker of malignant transformation.

RESUMO -A paralisia cerebral é doença que pode cursar com distúrbios da deglutição (disfagias orofaríngeas). O objetivo deste artigo foi caracterizar e comparar a deglutição em 32 crianças com esta doença, pela avaliação clínica fonoaudiológica e videofluoroscópica, com ênfase na aspiração traqueal, Os resultados mostraram importante comprometimento da fase oral. Na fase faríngea a aspiração, a incompetência velofaríngea e o resíduo em recessos faríngeos, foram os achados mais encontrados. A aspiração foi encontrada mais frequentemente com líquidos, antes e durante a deglutição. Na avaliação clínica e na videofluoroscopia, a hiperextensão cervical foi a anormalidade postural mais encontrada. A videofluoroscopia confirmou a presença de aspiração na maioria dos casos que apresentaram sinais sugestivos de aspiração na avaliação clínica da deglutição. Concluímos que a avaliação clínica e a videofluoroscópica são complementares na avaliação da deglutição; juntas podem indicar a conduta mais adequada na reabilitação.PALAVRAS-CHAVE: paralisia cerebral, videofluoroscopia, deglutição, disfagia. Clinical and videofluoroscopic evaluation of deglutition in children with tetraparetic spastic cerebral palsyABSTRACT -Cerebral palsy is a condition that may be associated with swallowing disorders, that is, oropharingeal dysphagia. The aim of this study was to characterize and compare the swallowing processes of 32 children with this condition, by clinical and videofluoroscopic evaluation, with special focus on tracheal aspiration detectability. Results show an important compromise of oral phase. The most important findings during the pharyngeal phase were velopharingeal incompetence and residuals on the pharyngeal recesses. Aspiration was more common with liquids, before and after deglutition. On clinical and videofluoroscopic evaluation, cervical hyperextension was the commonest postural abnormality. Videofluoroscopy confirmed the occurrence of aspiration on most of the cases that presented suggestive signs of aspiration during clinical evaluation. We conclude that clinical and videofluoroscopic evaluations are complementary on deglutition evaluation and together may point to the most specific rehabilitation procedure. A paralisia cerebral (PC) do tipo tetraparética espástica representa a forma clínica mais grave das paralisias cerebrais. Em sua maioria, as crianças apresentam retardo mental, crises convulsivas e grave comprometimento motor. Estas manifestações são consideradas fatores de risco para distúrbios alimentares: pela alteração motora da dinâmica orofaringeana; pela falta de compreensão do contexto alimentar e dificuldade na ação motora voluntária da fase oral, podendo alterar a sequencialização da fase faríngea; e pela gravidade da aspiração traqueal. Nas disfagias orofaringeanas, as complicações mais difí-ceis de gerenciamento clínico são as afecções pulmonares causadas pela aspiração. Assim, a detectabilidade e caracterização dessa aspiração, que ocorre na fase faríngea, são primordiais para o prognósti-co e reabil...

We believe that the high expression of TGF-beta1 in inflammatory mucosa compared with the low expression in polyps may reflect an important role in the inhibitory mechanisms of nasal polyposis.

Adenotonsillar hypertrophy leads to more severe polysomnographic patterns in preschool-age children. More severe apnea is observed in younger children with adenotonsillar hypertrophy than in older ones.
