Early medical and surgical treatment is essential to improve the prognosis of AIFRS patients. A poorer prognosis was associated with underlying disease and extensiveness of AIFRS, but not to the fungus isolated.
Purpose: Hyperbaric oxygen therapy (HOT) consists of intermittent inhalations of 100% oxygen at a pressure higher than 1 atm. It is an important adjuvant therapy in pathological processes like soft tissue infections, radiation injury, gas gangrene, osteomyelitis and decompressive diseases. Cisplatin, a potent antineoplastic drug, widely used in cancer therapy is highly ototoxic causing bilateral, irreversible damage to the hearing of high frequency sounds (4-8 KHz). Objective:This experimental study conducted at the Faculty of Medicine of Ribeirao Preto, University of Sao Paulo aims to evaluate Hyperbaric Oxygen Therapy as an otoprotection agent against drug toxicity. Methods: Albino guinea pigs were divided into two groups: in Group A, 5 animals (10 cochlea) received cisplatin, i. p., 8.0 mg/kg/day during three days and afterwards were submitted to HOT; in Group B, 3 animals (6cochlea) received cisplatin, i. p. 8.0mg/kg/day during three days. Guinea pigs were evaluated by acoustic otoemissions (AOE) and scanning electron microscopy (SEM). Results: Group B animals showed loss of auditory functions as measured by AOE and distorted outer hair cells by SEM. In Group A, outer hair cells shown by SEM images were mostly preserved. Conclusion: It is presumed that Hyperbaric Oxygen Therapy has a protector effect against cisplatin ototoxicity.Key words: Hyperbaric Oxygen Therapy. Ototoxicity. Otoprotection. Cisplatin. RESUMOIntrodução: A Oxigenoterapia hiperbárica (OHB) envolve a inalação de oxigênio a 100% sob uma pressão maior que 1 atm. E um importante modo de terapia adjuvante para processos patológicos, tais como: infecção de partes moles, lesões actínicas, gangrena gasosa, osteomielite e doença descompressiva. A cisplatina e uma potente droga antineoplásica largamente utilizada para o tratamento de câncer. A ototoxicidade e um importante efeito colateral desta droga, causando dano irreversível, bilateral, na capacidade de ouvir sons de alta freqüência (4 -8 KHz). Este estudo experimental, realizado na Faculdade de Medicina de Ribeirao Preto da Universidade de São Paulo nos anos de 2005 e 2006. Objetivo: Avaliar o papel da Oxigenoterapia Hiperbárica como agente otoprotector contra a toxicidade de drogas. Métodos: Cobaias albinas divididas em 2 grupos Grupo A: com 5 cobaias (10 cócleas) que receberam cisplatina 8,0 mg/kg/dia, via intraperitoneal por 3 dias, submetidas posteriormente a OHB. Grupo B: com 3 cobaias (6 cócleas) que receberam cisplatina 8,0 mg/kg/dia, via intraperitoneal por 3 dias. As cobaias foram avaliadas através de otoemissões acústicas (OEA) e por microscopia eletrônica de varredura (MEV). Resultados: Encontramos no grupo B perda da função auditiva medida pela OEA e distorção das células ciliares externas a MEV. No grupo A, a MEV as células ciliares externas foram preservadas em sua grande maioria. Conclusão: Assim podemos supor que a Oxigenoterapia Hiperbárica tem um efeito otoprotetor contra a ototoxicidade induzida pela cisplatina.
Summary Introduction: Fungal mastoidits by Aspergillus fumigates predominantly occurs in immunosuppressed patients. Diagnosis is usually hard and disease is potentially fatal. Treatment is comprised of antifungal therapy, surgical debridement and immunosuppression correction. Case Report: This article reports a case of fungal mastoiditis in a patient with acquired immunodeficiency syndrome (AIDS). The treatment performed was that of surgery associated with antifungal therapy. The patient's facial nerve was not affected, what does not exclude potentially fatal complications of mastoiditis.
Pl astic surgery is based on improving esthetic for the patient. In most services, the surgery outcome is evaluated in a subjective manner.Aim: to objectively assess the degree of patient satisfaction one year after rhinoplasty using the Rhinoplasty Outcome Evaluation questionnaire at a referral academic center. Materials and Methods:69 patients operated in the otorhinolaryngology service were selected. The patients were operated upon by third year residents during the period from January to December 2007 and answered the questionnaire translated by the authors of this study.Results: we obtained a mean value of 73.25% of satisfaction for primary rhinoplasty and a mean value of 72.02% of satisfaction for secondary rhinoplasty.Conclusion: the level of satisfaction presented by the patients was considered to be very good.

Inacomodações do indivíduo órfão -a subjetividade na arte, da modernidade à pós-modernidadeUnaccommodations of the orphans individual -the subjectivity in the art, from modernity to post-modernity por Camila Yassuda RESUMO Trazendo referências das Artes Visuais e unindo-as a alguns "achados" da Literatura, procuro, por meio deste artigo, elaborar uma reflexão, com embasamentos filosóficos e históricos, acerca de aspectos da subjetividade contemporânea relacionados à crise existencial, e seus efeitos na produção artística. O indivíduo pós-moderno quer reafirmar o propósito de sua existência depois que este foi extinto. Dito indivíduo encontra-se, portanto, numa errância labiríntica, desde que fora desprovido das certezas absolutas e da crença em sua finalidade de existir, que delatam a ausência do progresso humano. Essa é a emboscada e o ponto de partida que nos impele à invenção do "depois", ou seja, á pós-modernidade.
