Diagnóstico de tumores do angulo ponto-cerebelar com o auxílio de técnicas de inteligência artificial
LEIT?O, FLáVIO;GOMES, FERNANDO C.;DIóGENES, SEBASTIO;LEIT?O FILHO, FLáVIO;

Abstract: we are concerned in this paper with learning classification procedures from known cases. more precisely, we provide a diagnostic model that discriminate between cerebellum-pontine angle (cpa) tumors and otorhinolaryngological (ent) disorders. usually, in order to distinguish between cpa tumors and ent disorders one must perform clinical-neurological examination together with expensive radiological imagery (ct and mri). the proposed model was obtained through artificial intelligence methods and presented a good accuracy level (88.4%) when tested against new cases, considering only clinical examination without radiological imagery results.

Abstract: Trata-se de estudo multidisciplinar, cujo objetivo é a obten o de modelo discriminatório entre diagnóstico de tumores do angulo ponto-cerebelar (APC) e de distúrbios otorrinolaringológicos. Presentemente, a realiza o de um acurado exame neurológico e/ou otorrinolaringológico é incapaz de firmar diagnóstico de tumor do APC, sem valer-se de exames radiológicos de alto custo (tomografia computadorizada, ressonancia magnética). O modelo proposto foi obtido através da utiliza o de técnicas de inteligência artificial e apresentou bom nível de acurácia (88,4%) no teste de novos casos, considerando-se apenas o exame clínico e sem o auxílio de exames radiológicos.

Abstract: epistaxis remains one of the most common otolaryngology emergencies. despite considerable interest in the subject, there is still no consensus on the most appropriate primary therapeutic modality. aim: the purpose of this study was to evaluate the bleeding source of acute or recurrent epistaxis in adults. study design: clinical prospective. material and method: thirty adults patients with acute or recurrent epistaxis were evaluated through the use of frontal light and endoscope for identification of the bleeding source in the nasal cavity. results: use of the nasal endoscope allowed diagnosis of the bleeding site in all patients. conclusion: a careful examination of the posterior nasal cavity allows identification of the bleeding source in most patients and should be a routine procedure.

Abstract: the coral tree (erythrina velutina) is a fast growing tree with medicinal properties. the aim of this study was to evaluate the allelopathic effects of aqueous extract of seeds, flowers and bark of coral tree on seed germination and seedling development of lettuce cv. m?nica sf fi. the experimental design was completely randomized with seven treatments [seed extract at 100°c, seed extract at 25°c, bark extract at 100°c, bark extract at 25°c, flower extract at 100°c, flower extract at 25°c and distilled water (control)] with four replications. the extracts of seeds, independent of the extraction temperature decreased the percentage and speed of germination of lettuce and affected the development of the seedlings. the other extracts did not affect germination, but caused the appearance of abnormal seedlings and dead. the aqueous extract of seeds of coral tree has allelopathic potential in the seeds of lettuce cv. m?nica sf fi.

Abstract: introduction: an antrochoanal polyp, or killian?s polyp is a benign solitary polypoid lesion that affects mainly children and young adults. studies demonstrate that killin?s polyp generally represents 4-6% of all nasal polyps. however, in the pediatric population this percentage reaches 33%. it originates from a hypertrophy of the mucous membrane on the maxillary sinus antrum, and it grows for unknown reasons, through the maxillary sinus ostium towards the nasal cavity and the choana - the posterior portion of the pharynx. aim: to evaluate the result of the surgical treatment on patients assisted in the department of otorhinolaryngology of the walter cantídio university hospital - medical school of the federal university of ceará, mainly on the surgical technique employed and the efficacy of each technique in controlling the disease. materials and methods: retrospective study, accomplished through a chart analysis from the patients submitted to polypectomy because of killian?s polyps or other nasal polyps, operated from march 1st, 1991 to april 30th of 2001, in the department of otorhinolaryngology of the medical school of the walter cantídio university hospital of the federal university of ceará. results: nine patient (56.6%) were males and 7 (43.8%) were females. eleven (68.75%) patients were between 8 and 20 years of age. predominant symptoms were unilateral nasal obstruction (81.3%) and purulent rhinorrhoea (43.8%). the most common procedure employed was the combined approach: external and endonasal, in 87.5% of the cases. antrochoanal polyp removal procedure accounted for 21.6% of all the surgical procedures accomplished in the same period for the removal of nasal polyps. postoperative recurrence was of 12.5%. conclusions: antrochoanal polyp was an affection that prevailed among children and young adults. the combined external and endonasal approach was the one most used. despite maxillary sinus approach to the polyp origin, postoperative recurrence is a possib

Abstract: introduction: the lowered temporal meninges and/ or anterior sigmoid sinus are contiditions that can determine surgical difficulties in performing mastoidectomy. objective: to correlate in the tomography the extent of the prolapse of the sigmoid sinus and of temporal meninges with the surgical difficulty in the mastoidectomy. method: the tomographic measurements of prolapse sigmoid and of temporal meninges were correlated with the presence or non-presence of the surgical difficulty observed during the mastoidectomy procedure in patients with ostomatoiditis chronic (n=30). form of study: contemporary cohort transverse. results: in 10 patients were observed surgical difficulty distributed as: due to prolapse of the sigmoid sinus (n = 2) or temporal meninges prolapse (n = 7) or both (n = 1). in patients in which the surgical difficulty was due to sigmoid sinus prolapse, the tomography distance of the anterior border of the sigmoid sinus to posterior wall of external auditory canal was lower than 9 mm. in patients in which surgical difficulty was due to temporal meninges prolapse, the tomographic distance to the upper plane of the petrous bone was 7 mm. conclusion: the computerized tomography distance between the temporal meninges and the upper plane of the petrous bone 7 mm and the distance of the anterior border of the sigmoid sinus to posterior wall of external auditory canal was lower than 9 mm are predictive to the surgical difficulties to perform mastoidectomy.
