Case presentation of amyloidosis of the gastrointestinal tract with CT enterography

Poster no. C-1406Amyloidosis is an uncommon heterogeneous group of diseases caused by extracellular deposition of the amyloid protein. The amyloid deposits demonstrate apple-green birefringence under a polarized light microscope after staining with Congo red, and presence of rigid and non-branching fibrils of 7.5-10 nm diameters on electron microscopy. Amyloidosis can be classified into systemic or localized forms. The gastrointestinal tract (GIT) is the commonest site of involvement (98%) of systemic...link_to_OA_fulltex

Jacobson's nerve schwannoma presenting as middle ear mass

Schwannoma is one of the common benign middle ear space tumors. Middle ear space schwannomas may originate from the nerves of the tympanic cavity or by extensions From outside the middle ear space. In the English-language literature, the facial nerve and chorda tympani nerve, but not yet the tympanic branch of glossopharyngeal nerve (Jacobson's nerve), have been reported as the origins of intrinsic middle ear space schwannomas. We present the clinical and radiologic features of a middle-space schwannoma originating from Jacobson's nerve, and suggest that such a tumor be included in the differential diagnosis of middle ear tumors

The venous hum as a cause of vascular pulsative tinnitus

Tinnitus is one of the most common complaints in medical practice. The venous hum is described as an uncommon cause of vascular tinnitus, seldom remembered or recognized as a clinical entity. AIM: The aim of this paper is to identify the venous hum cases at Tinnitus Ambulatory at UNIFESP-EPM and compare them to literature. MATERIAL AND METHOD: retrospective research of venous hum cases identified at UNIFESP-EPM from April 1997 to April 2003, analyzing the following parameters: age of appearance, frequency, affected side, presence of associated hearing loss and dizziness, improvement and worsening factors, audiometry results, vestibular exam and computadorized tomography of temporal bones, evolution and treatment performed. RESULTS: pulsative tinnitus happened in 7,5% and venous hum in 3% of total cases of the patients with tinnitus, all in women, with no preference for age of appearance, most common at left ear. All patients have improved with clinical treatment and surgery was not needed in any case. CONCLUSION: The venous hum is not an uncommon cause of tinnitus (39% of pulsative tinnitus) as described in literature. Treatment should be performed by acting in responsible and decurrente factors caused by tinnitus. In great number of cases venous hum spontaneously disappears, needing no treatment. Surgical treatment is rarely indicated and must be reserved only in cases with no improvement with clinical treatment.Zumbido é uma das queixas otológicas mais comuns com que o otorrinolaringologista se depara. O hum venoso é descrito como uma causa pouco comum de zumbido vascular, pouco lembrado ou reconhecido como entidade clínica. OBJETIVO: O objetivo do estudo é identificar os casos de hum venoso dentre os pacientes com zumbido pulsátil atendidos no Ambulatório de Zumbido da Disciplina de Otorrinolaringologia da UNIFESP-EPM e compará-los com a literatura. MATERIAL E MÉTODO: Estudo retrospectivo dos pacientes com hum venoso realizado na UNIFESP-EPM de abril de 1997 a abril de 2003, analisando-se os parâmetros: idade de aparecimento, freqüência, lado acometido, presença de perda auditiva e tontura associadas, fatores de piora e melhora, resultados de audiometria, exame vestibular e tomografia computadorizada de ossos temporais, evolução e tratamento realizados. Foi utilizado um protocolo de exames e tratamento e os resultados foram comparados com os da literatura. RESULTADOS: O zumbido pulsátil ocorreu em 7,5% e o hum venoso em 3% do total de pacientes com zumbido, todos no sexo feminino, sem prevalência por época de aparecimento, acometendo mais a orelha esquerda. Em todos os pacientes houve melhora com tratamento clínico, não sendo necessária intervenção cirúrgica em nenhum caso. CONCLUSÃO: O hum venoso não é uma causa incomum de zumbido (39% dos zumbidos pulsáteis) como citado na literatura. O tratamento deve ser realizado atuando-se sobre os fatores responsáveis pelo zumbido e decorrentes do mesmo. Em grande número de casos o mesmo desaparece espontaneamente, não necessitando de tratamento. O tratamento cirúrgico raramente é necessário, devendo ser reservado apenas aos casos em que não haja melhora com o tratamento clínico.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de OtorrinolaringologiaUNIFESP, EPM, Depto. de OtorrinolaringologiaSciEL
