- ItemAcesso aberto (Open Access)Análise do clearance mucociliar nasal e dos efeitos adversos do uso de CPAP nasal em pacientes com SAHOS(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2004-04-01) Ferri, Ricardo Gimenes [UNIFESP]; Zonato, Adriane; Guilherme, Arnaldo [UNIFESP]; Gregório, Luiz Carlos [UNIFESP]; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP)Since 1981 the use of positive airway pressure through the nasal CPAP has been considered the main clinical treatment of the SAOS- sleep obstructive apnea syndrome, despite its low adhesion on a long- term. Some authors report that the nasal complaints from the continuous positive airway pressure in the nasal cavity are the main causes for the therapy discontinuance. This would probably occur because the treatment would lead to epithelium alterations and changes in the mucociliarytransport and hence, a greater number of upper respiratory infections. AIM: To evaluate the nasal mucociliary clearance in patients with SAHOS under nasal CPAP use through saccharin test, and correlate the adverse effects of this therapy with the treatment endurance and the pressure level used in it. STUDY DESIGN:Clinical study case-control. MATERIAL AND METHOD: Twenty five patients, carriers of SAHOS - between their 18 and 70 - submitted to nasal CPAP use for one month, were followed-up at the Instituto do Sono (UNIFESP-EPM) and subjected to the saccharin test. The results were compared to a group of 25 normal individuals. RESULTS: There was no statistical difference among the groups regarding the saccharin test. The adverse effects were present in 84% of the sample, being 60% for nasal dryness and 36% for nasal obstruction. CONCLUSIONS: The mucociliary transport stays normal in the SAHOS group submitted to nasal CPAP use and the nasal obstruction and nasal dryness do not present correlation with the treatment time and pressure level used by the device.
- ItemAcesso aberto (Open Access)Computerized analysis of snoring in sleep apnea syndrome(Associação Brasileira de Otorrinolaringologia e Cirurgia Cervicofacial, 2011-08-01) Shiomi, Fabio Koiti; Pisa, Ivan Torres [UNIFESP]; Campos, Carlos José Reis De [UNIFESP]; Instituto Federal de Educação Tecnológica de São Paulo; Universidade Federal de São Paulo (UNIFESP)The International Classification of Sleep Disorders lists 90 disorders. Manifestations, such as snoring, are important signs in the diagnosis of the Obstructive Sleep Apnea Syndrome; they are also socially undesirable. OBJECTIVE: The aim of this paper was to present and evaluate a computerized tool that automatically identifies snoring and highlights the importance of establishing the duration of each snoring event in OSA patients. MATERIAL AND METHODS: The low-sampling (200 Hz) electrical signal that indicates snoring was measured during polysomnography. The snoring sound of 31 patients was automatically classified by the software. The Kappa approach was applied to measure agreement between the automatic detection software and a trained observer. Student's T test was applied to evaluate differences in the duration of snoring episodes among simple snorers and OSA snorers. RESULTS: Of a total 43,976 snoring episodes, the software sensitivity was 99. 26%, the specificity was 97. 35%, and Kappa was 0. 96. We found a statistically significant difference (p <0. 0001) in the duration of snoring episodes (simple snoring x OSA snorers). CONCLUSIONS: This computer software makes it easier to generate quantitative reports of snoring, thereby reducing manual labor
- ItemAcesso aberto (Open Access)Indicação cirúrgica otorrinolaringológica em um ambulatório para pacientes com síndrome da apnéia e hipopnéia obstrutiva do sono(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2004-01-01) Martinho, Fernanda Louise [UNIFESP]; Zonato, Adriane Iurck; Bittencourt, Lia Rita Azeredo [UNIFESP]; Gregório, Carla Lobato; Gregório, Luiz Carlos [UNIFESP]; Tufik, Sergio [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Universidade de São Paulo (USP); Faculdade de Medicina do ABCAIM: Otolaryngology surgical procedure is an option for obstructive sleep apnea-hypopnea syndrome (OSAHS) treatment. The objective of this study is to show which procedures can be done well as their indications. STUDY DESIGN: Clinical retrospective. METHOD: 223 patients with OSAHS were studied in Otolaryngology Department of UNIFESP. Every patient had a previous polissonography, and they were analyzed and treatment options were proposed. The treatment options were divided in no surgical (CPAP, dental appliance and general measures) and surgical procedures (pharynx surgery, rhinosurgery and maxillofacial surgery). RESULT: 100 patients (44,8%) had surgery indication, and 168 procedures were proposed. The majority uvulopalatopharyngoplasty and radiofrequency of the soft palate were indicated in mild and moderate OSAHS cases and maxillomandibular surgery were indicated in severe cases. Tonsillectomy and rhinosurgery were indicated independently of OSAHS severity. CONCLUSION: The otolaryngological surgery is an option in OSAHS treatment, and your indication depends on OSAHS severity. The surgical procedure can be done whit curative intetion or to avoid CPAP use.
- ItemAcesso aberto (Open Access)Sleep disorders are associated with impulsivity in school children aged 8 to 10 years(Academia Brasileira de Neurologia - ABNEURO, 2005-09-01) Medeiros, Marilaine [UNIFESP]; Carvalho, Luciane Bizari Coin de [UNIFESP]; Silva, Tatiana A. [UNIFESP]; Prado, Lucila Bizari Fernandes do [UNIFESP]; Prado, Gilmar Fernandes do [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)CONTEXT: Sleep has an important function in the physical and emotional development of children. Some studies suggest an association between impulsivity and sleep disorders. However, little is known about this association in schoolchildren aged 8 to 10 years. METHOD: We studied 1180 children, 547 with sleep disorders (SD) and 633 without SD (control group), classified with SD questionnaires. Within the SD group, 53 children with sleep-related respiratory disorders (SRRD) and 521 children with non-respiratory sleep disorders (NRSD) were analyzed. We acessed emotional indicators of impulsivity with Bender test. RESULTS: More SD children presented impulsivity than control group (p<0.05). More NRSD and 10 years old children presented impulsivity than control group of the same age (p=0.001). Impulsivity and SRRD were associated with 8 years old children (p<0.05). CONCLUSION: Children with SD, 8 years old children with SRRD, and 10 years old children with NRSD presented higher proportion of impulsivity than control children.
