- ItemEmbargoComparação da eficiência do laser de diodo 980 nm versus glicose a 75% na oclusão de veias da orelha de coelhos(Universidade Federal de São Paulo (UNIFESP), 2010-09-29) Lima, Paulo Roberto da Silva [UNIFESP]; Baptista-Silva, José Carlos Costa [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Contexto. Por ser o laser um método novo no tratamento das varizes, há muitos mitos e dúvidas com relação à sua eficácia; veio a necessidade de compará-lo às substâncias esclerosantes mais utilizadas em nosso meio. Assim, é relevante responder a pergunta de pesquisa: qual a eficiência do laser de diodo 980 nm em comparação à glicose 75% na oclusão de veias em orelha de coelho? Objetivo. Comparar a eficiência do laser de diodo 980 nm à glicose 75% na oclusão de veias em orelha de coelho. A hipótese é que o laser de diodo 980 nm tenha uma eficiência de 30% em relação à glicose 75%. Tipo de estudo. Ensaio aleatório em animais de laboratório por 21 dias. Local. Biotério do Laboratório de Tecnologia Farmacêutica (LTF) do Campus I da Universidade Federal da Paraíba, João Pessoa – PB. Amostra. Orelhas de coelhos machos. Procedimentos. Grupo L (LASER): 15 orelhas tratadas com laser e grupo G (glicose 75%): 15 orelhas tratadas com glicose 75%. Variáveis. Primárias: veias esclerosadas e/ou ocluídas. Secundárias: segurança. Complementares: volume da substância administrada, calibre e tamanho do vaso, peso e idade do coelho. Método estatístico. O tamanho da amostra foi estimado em 30 orelhas com base na literatura e para respeitar as normas da COBEA. A análise estatística será realizada com o teste exato de Fisher associado ao Risco Relativo (RR) e calculando o intervalo de confiança (IC) de 95% para cada ponto estimado Resultados. Característica da amostra. Congestão vascular no grupo G foi 87% (13/15, IC 95% 60 a 98) e no grupo L de 67% (10/15, IC 95% 38 a 88) com P = 0,3898 e RR de 1,30 (IC 95% 0,86 a 1,96). Hiperplasia intimal no grupo G foi 13% (2/15, IC 95% 2 a 40); e no grupo L 7% (1/14, IC 95% 0 a 32) com P = 1 e RR de 2,00 (IC 95% 0,20 a 19,79). Variáveis. A incidência de esclerose ou oclusão venosa foi no grupo G foi de 53% (8/15, IC 95% 27 a 79) e no grupo L 20% (3/15, IC 95% 4 a 49) com de P bicaudal foi de 0,1281, seu RR (risco relativo) usando a aproximação de Katz foi igual a 2,66 IC 95% 0,87 a 8,15 Conclusão. A eficiência do laser de diodo 980 nm em comparação à glicose 75% na oclusão de veias é a mesma.
- ItemAcesso aberto (Open Access)Corpo estranho de orelha, nariz e orofaringe: experiência de um hospital terciário(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2006-04-01) Tiago, Romualdo Suzano Louzeiro [UNIFESP]; Salgado, Daniel Cauduro; Corrêa, Juliano Piotto; Pio, Márcio Ricardo Barros; Lambert, Ernani Edney; Universidade Federal de São Paulo (UNIFESP); Hospital do Servidor Público Municipal de São Paulo Serviço de OtorrinolaringologiaThe ocurrence of foreign bodies in otorhinolaryngology is reason of constant searches for emergency services. OBJECTIVE: To value the incidence of patients with foreign body, to analyze the clinical situation and the treatment in these cases. METHOD: The prospective study was realized in 81 patients with diagnosis of foreign body of nose, ear or oropharynx in the otorhinolaryngology service of the Hospital do Servidor Público Municipal de São Paulo between april/2003 and march/2005. RESULTS: 57 cases of foreign body of ear, 13 cases of nose and 11 of oropharynx. These patients, 51.85% were men and 48.15% were women. The age average was 23 years old. The average of the evolution time was 18.36 days, being that 38.27% these cases were taken care in less 24 hours of evolution. Inside the total of patients, 83.95% received initial attendance in the otorhinolaryngology clinic, and 16.05% came of another service after some previous removal attempt. The most common symptom of the foreign bodies cases of oropharynx it was odinofagia present in 90.91% of the cases; in the foreign bodies of nose, the unilateral rhinorrhea and cacosmia were present in 46.15 of the cases; in the foreign bodies of ear, 38.60% evolved without symptoms and 28.07 with hipoacusia. The most frequent foreign body of oropharynx it was the fish spine (54.55%); in the nose it was the paper (30.77%); and in the ear it was the cotton (31.58%). The complications resulting of the presence of foreign body or about the manipulation of these had been found in 13 cases (16.05%). CONCLUSION: Most cases of foreign body conditions, in which a non-specialist professional or a non-professional person previously handles its removal, have a bad evolution with emerging complications. Such outcomes strengthen the fact that an otorhinolaryngologist using the proper equipment must treat patients with foreign body.
- ItemAcesso aberto (Open Access)Potencial evocado auditivo de estado estável por via aérea e via óssea em crianças de zero a seis meses sem e com comprometimento condutivo(CEFAC Saúde e Educação, 2014-06-01) Garcia, Michele Vargas; Azevedo, Marisa Frasson de [UNIFESP]; Biaggio, Eliara Pinto Vieira; Didoné, Dayane Domeneghini; Testa, Jose Ricardo Gurgel [UNIFESP]; Universidade Federal de Santa Maria; Universidade Federal de São Paulo (UNIFESP)Purposecheck the feasibility of searching the minimum response of the Auditory Evoked Potential Steady State by air and bone conduction in children from birth to six months and measure the “gap” air-bone of children with impairment conductive. Methodwe evaluated 60 children from birth to six months, 30 with and 30 without impairment conductive, divided into a control group and study group. Were measured acoustic impedance, otorhinolaryngological evaluation, and the Auditory Evoked Potential Steady State by air and bone conduction. The Auditory Evoked Potential Steady State was carried by air with insert earphones and bone with bone vibrator. By airway responses were surveyed in both ears and bone captured only the left ear. Resultin the control group, there was a predominance of type curve “A”. In the study group, there was a predominance of type curves “B” and “C”. In otorhinolaryngological evaluation found in the control group showed up normal. In the study group, opacity and tympanic membrane retraction. The Auditory Evoked Potential Steady State in the control group by air responses were around 17.2, 26.2, 22, 7 and 19.8 dBHL at frequencies 500 to 4 kHz and bone conduction between 18.8 to 20dBHL. In the study group by airway responses were 53, 56, 50.2 and 48dBNA to 500 to 4kHz and bone of 25, 25, 20 and 20dBHL. Conclusionit was possible to perform the Auditory Evoked Potential Steady State by air and bone conduction in children from birth to six months of age and the “gap” air-bone was around 20dB in children with impairment conductive.
- ItemAcesso aberto (Open Access)Subjective visual vertical with the bucket method in Brazilian healthy individuals(Assoc Brasileira Otorrinolaringologia & Cirurgia Cervicofacial, 2016) Ferreira, Maristela Mian [UNIFESP]; Cunha, Fabiana [UNIFESP]; Gananca, Cristina Freitas [UNIFESP]; Gananca, Mauricio Malavasi [UNIFESP]; Caovilla, Heloisa Helena [UNIFESP]Introduction: The capacity of a healthy individual to estimate the true vertical in relation to the Earth when a fluorescent line is aligned in a completely dark room is called the subjective visual vertical. Objective: To evaluate subjective visual vertical using the bucket method in healthy Brazilian individuals. Methods: Binocular subjective visual vertical was measured in 100 healthy volunteers, 50 females and 50 males. The volunteers indicated the estimated position in which a fluorescent line inside a bucket reached the vertical position. A total of ten repetitions were performed, five clockwise and five counterclockwise. Data were tabulated and analyzed statistically. Results: It was observed that the highest concentration of absolute values of vertical deviation was present up to 3, regardless of gender, and the vertical deviation did not increase with age. The analysis of the mean of the absolute values of deviations from the vertical of 90% of the sample showed a maximum value of 2.6, and at the analysis of 95%, the maximum value was 3.4 degrees deviation from the vertical. Conclusion: The bucket method is easy to perform and interpret when assessing the deviation of the subjective visual vertical in relation to the true vertical in healthy Brazilian individuals.
