Revista Brasileira de Otorrinolaringologia , 2003,
Abstract: Os tumores da laringe e hipofaringe apresentam alta incidência no Brasil, sendo o sexto sítio mais comum entre os tumores malignos no sexo masculino. O diagnóstico inicial geralmente é realizado com les es em estadio clínicos avan ados diminuindo o sucesso do tratamento instituído. OBJETIVOS: Avaliar a evolu o de 60 pacientes com carcinoma epidermóide de seio piriforme, considerando tratamento instituído, complica es e sobrevida estimada em 5 anos. FORMA DE ESTUDO: Estudo retrospectivo. MéTODO: Os testes estatístico utilizados foram o método de Kaplan-Meier e o teste exato de Fisher. RESULTADOS: Dos 60 pacientes, 43 foram submetidos a tratamento cirúrgico seguido de radioterapia. Atualmente 27,9% est o vivos sem doen a, 11,6% vivos com doen a, 9,4% mortos sem doen a, 34,8% mortos com doen a e perda de seguimento de 16,3%. A complica o pós-operatória mais freqüente foi a fístula cutanea. A recidiva local ocorreu em 5 pacientes, regional em 6, loco-regional em 3 e metástase à distancia em 6. N o houve correla o entre margem cirúrgica comprometida e sobrevida em 20 pacientes com recidiva tumoral (Teste de Fisher). Aplicando a curva de sobrevida atuarial pelo método Kaplan-Meier, obtivemos média de sobrevida em 5 anos de 23,2 meses. CONCLUS O: A principal complica o pós-operatória foi a fístula cutanea, sendo tratada clinicamente. A margem cirúrgica comprometida n o alterou o prognóstico, apesar de ser sempre um dos princípios da cirurgia oncológica. A principal falha no tratamento foi a recidiva locorregional. A curva de sobrevida atuarial (Kaplan-Meier) em cinco anos apresentou média de 23,2 meses.

Abstract: laryngeal and pharyngeal tumors exhibit a high incidence in brazil, occupying the sixth position as the most frequent cancer sites in males. the initial diagnosis is usually made with the lesion at an advanced clinical stage, hindering success of any treatment employed. aim: to evaluate the evolution and prognosis of patients with epidermoid carcinoma of the hypopharynx, considering treatment of choice, complications and estimated 5-year survival. study design: this is a retrospective study methods: using kaplan-meier and exact fisher test. 60 patients with advanced epidermoid carcinoma of the hypopharynx, with the epicenter located at the pyriform sinus, were enrolled. results: 43 of the 60 patients were submitted to surgical treatment followed by radiotherapy. currently 27.9% of the patients are alive free of the disease, 11.6% are alive with the disease, 9.4% died from other causes, 34.8% died due to the disease and 16.3% interrupted the follow-up. the most frequent postoperative complication was salivary fistula. five patients evolved with local recurrence, 6 with regional recurrence, three with loco-regional recurrence and six with distant metastasis. there was no correlation between small surgical safety margins and survival in the 20 patients presenting recurrences (fisher test). applying the actuarial survival curve with the kaplan-meier method we obtained a 5-year survival average of 23.3 months. conclusion: the major post-surgical complication in hypopharyngeal carcinoma treatment was salivary fistula, being successfully treated without surgery. small surgical safety margin did not influence the prognosis, even though it is a failure according to one of the fundamental cancer surgery predicaments. the major feature of treatment failure was loco-regional recurrence. the actuarial five-year survival curve (kaplan-meier) averaged 23.3 months.

Abstract: context and objective: women infected by hiv are more likely to have cervical cancer and its precursors. treatment of the precursor lesions can prevent this neoplasia. the aim of this study was to assess the likelihood of recurrent cervical intraepithelial neoplasia grades 2 or 3 (cin 2-3) in hiv-infected women, compared with hiv-negative women, all treated by large loop excision of the transformation zone (lletz). design and setting: a cohort study in instituto fernandes figueira, funda??o oswaldo cruz (iff-fiocruz), rio de janeiro. method: 55 hiv-positive and 212 hiv-negative women were followed up after lletz for cin 2-3 (range: 6-133 months). results: the incidence of recurrent cin 2-3 was 30.06/10,000 woman-months in the hiv-positive group and 4.88/10,000 woman-months in the hiv-negative group (relative risk, rr = 6.16; 95% confidence interval, ci: 2.07-18.34). the likelihood of recurrence reached 26% at the 62nd month of follow-up among the hiv-positive women, and remained stable at almost 0.6% at the 93rd month of follow-up among the hiv-negative women. we were unable to demonstrate other prognostic factors relating to cin recurrence, but the use of highly active antiretroviral therapy (haart) may decrease the risk of this occurrence among hiv patients. conclusion: after lletz there is a higher risk of recurrence of cin 2-3 among hiv-positive women than among hiv-negative women. this higher risk was not influenced by margin status or grade of cervical disease treated. the use of haart may decrease the risk of this occurrence in hiv patients.

Abstract: Hemorrhagic gastroenteritis (GHE) is a common motivation to hospitalization and mortality between puppies. Considering the beneficial effects of probiotics in the treatment of some gastrointestinal disorders, we evaluated the usefulness of the probiotic product in 100 puppies hospitalized because GHE. Fifth dogs were treated by intravenous fluid, antiemetic, antibiotics and probiotic product (G1), and the other 50 only by supportive and symptomatic therapy (G2). We accessed the titters of anticorpus anti-parvovirus by HI, fecal excretion of virus by HA and registered the duration of internation period and tolerance to probiotic ingestion. The titters of HI were similar between G1 and G2 in the samples from entrance (P = 0,553) and at the hospital discharge (P = 0,844), moreover arises during hospitalization in booth groups (P < 0,001). The fecal excretion of virus of G1 and G2 were similar in booth moments (P = 0,746 and P = 0,294, respectively) furthermore the G1 showed lowest fecal titters of virus at hospital discharge (P < 0,001). The internation period in the G1 variates one to 15 days and one to 10 days in the G2 group, without statistical difference between the groups (P = 0,70). The rate of mortality in the G1 was 37,50% (18/48) and 26% (13/50) in the G2, lacking statistical significance (P = 0,49). Probiotic tolerance was regular to excellent in 95% of the administrations, furthermore the animals that died demonstrate intolerance. These observation permits no established a relationship between the administration of Lactobacilus acidophillus based probiotic and shortening treatment duration, improved in the disease evolution or anticorpus production, likewise showed positive influence over fecal excretion of virus. Considering the parvovirosis, this is a desirable factor to decrease dissemination of the disease between susceptible population. A gastrenterite hemorrágica (GHE) é uma afec o comum em filhotes de c es, e motivo freqüente de interna o e mortalidade. Considerando que probióticos têm sido apontados como benéficos no tratamento destes pacientes, avaliamos o impacto da inclus o de probiótico à base de Lactobacilus acidophillus em 100 filhotes de c es com GHE, distribuídos em dois grupos de 50 indivíduos. Os c es do grupo 1 (G1), além da terapia indicada para GEH, constituída de fluido e antibiótico terapia e antiemético, receberam, por via oral, probiótico. Para os animais do grupo 2 (G2) foi adotada apenas a terapêutica convencional. Foram quantificadas as partículas virais nas fezes, pela aglutina o (HA) e os anticorpos (Ac) anti-par

Abstract: Com o objetivo de conhecer a frequência de desnutri o proteico-calórica ao diagnóstico e avaliar a sua importancia na evolu o clínica de crian as portadoras de Leucemia Linfocítica Aguda, com idades inferiores a quinze anos, estudamos trinta e oito crian as com Leucemia Linfocítica Aguda e sem tratamento prévio, atendidas no Hospital de Base de S o José do Rio Preto-SP, no período de Setembro/89 a Dezembro/97. Entre as crian as, 63,2% eram do sexo masculino e 36,8% do sexo feminino (1,7:1,0), a faixa etária predominante foi de cinco a nove anos (44,8%), seguida daquela entre um e quatro anos (36,8%), superscript three 10 anos (10,5%) e menores de um ano (7,9%). Ao diagnóstico, 52,7% eram eutróficos e 47,3% desnutridos (escore Z). Os índices nutricionais avaliados foram peso/estatura, estatura/idade e peso/idade e 21%, 34,2% e 31,5% deles, respectivamente, estavam abaixo da normalidade. Foi observada uma alta frequência de desnutri o ao diagnóstico. Porém, na avalia o do estado nutricional, entre os pacientes vivos e n o-vivos, a presen a de desnutri o n o foi estatisticamente significativa. Este estudo refor ou a evidência da necessidade de estabelecer uma rotina de avalia o nutricional ao diagnóstico, bem como, a presen a de um profissional especializado em nutri o, numa unidade de oncologia pediátrica.
