ABSTRACT

OBJECTIVE: To evaluate the applicability of the main categories of risk and morphological factors in the prognosis of gastrointestinal stromal tumors. METHODS: we retrospectively studied fifty-four cases of GIST, assessing the main prognostic factors of this neoplasis: risk levels, topography, size, mitotic index, necrosis, histological subtype and immunophenotype. We also verified their association and the reduction of overall survival. RESULTS: Univariate analysis showed that tumors with mitoses number greater than 5 per 50CGA (high-power fields), the presence of necrosis and a high risk for both the systems proposed by Fletcher and Miettinen had a significant association with reduced survival (p = 0.00001, 0.0056, 0.03 and 0.009, respectively). The remaining analyzed factors (size, histological subtype, topography and immunophenotype) had no such association. Multivariate analysis (Jacard index) showed that the Miettinen degree of risk was the one that best correlated with prognosis. CONCLUSION: the risk criteria of Fletcher and Miettinen are important in assessing the prognosis of patients with gastrointestinal stromal tumors, especially the latter, which adds to the mitotic index and the presence of tumor necrosis.


OBJETIVO: Avaliar a aplicabilidade das principais categorias de risco e de fatores morfológicos no prognóstico tumor estromal gastrointestinal. MÉTODOS: cinquenta e quatro casos de GIST foram estudados retrospectivamente considerando-se os principais fatores prognósticos da neoplasia: graus de risco, topografia, tamanho, índice mitótico, necrose, subtipo histológico e imunofenótipo. Foi também verificada a sua associação e a redução da sobrevida global dos pacientes. RESULTADOS: a análise univariada mostrou que os tumores com número de mitoses maior que 5/50CGA (campos de grande aumento), a presença de necrose, de alto risco tanto para os sistemas propostos por Fletcher, quanto para Miettinen tiveram associação significativa com redução da sobrevida (p=0,00001, 0,0056, 0,03 e 0,009, respectivamente). Enquanto que os demais fatores analisados (tamanho, subtipo histológico, topografia e imunofenótipo) não tiveram tal associação. A análise multivariada (índice de Jacard) demonstrou que o grau de risco de Miettinen foi aquele que melhor se relacionou com o prognóstico. CONCLUSÃO: os critérios de risco de Fletcher e de Miettinen são importantes na avaliação do prognóstico de pacientes com tumor estromal gastrointestinal, principalmente este último, que se soma ao índice mitótico e a necrose tumoral.

ABSTRACT

OBJECTIVE: To investigate the effect of administration of supraphysiological ß carotene on biological, laboratory and histological parameters of spontaneously hypertensive rats prone to stroke (SHR-sp). METHODS: we used 36 male rats divided into three groups, each containing 12 rats of the types Wistar SHR and SHR-sp, subdivided into six control animals and six animals treated with supraphysiological doses of ß carotene for two ten-week periods, interspersed by a one-week interruption. We carried out daily physical examination and blood pressure assessment. We collected blood for measurement of serum malondialdehyde; the liver and carotid arteries were subsequently harvested for histological examination. RESULTS: there was a temporary change in the color of hair, a significant decrease (p <0.0001) in blood pressure (20 mg ß carotene supplementation) and serum levels of malondialdehyde (p<0.05) and increased amount of elastic fibers in the carotid wall of SHR and SHR-sp. CONCLUSION: ß carotene supraphysiological supplementation caused no toxic effects, showed positive response in the modulation of blood pressure and lower serum malondialdehyde. No significant morphological changes were observed in the groups studied, except for an increase in the number of elastic fibers in the carotid muscular layer, suggesting elastosis in SHR and SHR-sp.

ABSTRACT

Objective: to investigate the effect of administration of supraphysiological âcaroteno on biological parameters (ectoscopy and blood pressure), laboratory (malondialdehyde) and histological (liver and carotid arteries) of spontaneously hypertensive rats prone to stroke (SHR-sp). Methods: we used 36 male rats were divided into three groups, each containing 12 rats Wistar, SHR and SHR-sp, subdivided into six control animals and six animals treated with supraphysiological doses of âcaroteno for two periods of ten weeks interspersed with one week interruption. In the experiment were assessed daily physical examination and blood pressure (plethysmography). At sacrifice, blood was collected for measurement of serum malondialdehyde, liver and carotid arteries for histological examination. Results: temporary change in color of the fur, decreased significantly (p<0.0001) blood pressure (20mg supplementation âcaroteno) and serum levels of malondialdehyde (p<0.05) and increased amount of elastic fibers in the carotid wall of SHR and SHR-sp. Conclusion: supplementation of supraphysiological âcaroteno caused no toxic effects, showed positive response in the modulation of blood pressure and lower serum malondialdehyde. No significant morphological changes were found in both groups, except an increase in the number of elastic fibers in the muscle layer carotid suggesting elastosis in SHR and SHR-sp. .


Objetivo: investigar o efeito da administração suprafisiológica de bcaroteno sobre parâmetros biológicos, laboratoriais e histológicos dos ratos espontaneamente hipertensos com tendência ao acidente vascular encefálico (SHR-sp). Métodos: utilizaram-se 36 ratos machos, distribuídos em três grupos, contendo cada um dos 12 ratos das linhagens Wistar, SHR e SHR-sp, subdivididos em seis animais controle e seis animais tratados com doses suprafisiológicas de âcaroteno por dois períodos de dez semanas, intercalados por uma semana de interrupção. No experimento foram avaliados diariamente o exame físico e a pressão arterial. Foi coletado sangue para dosagem sérica de malondialdeído; o fígado e as artérias carótidas para exame histológico. Resultados: alteração provisória na coloração dos pelos, diminuição significativa (p<0,0001) da pressão arterial (suplementação de 20mg de bcaroteno) e dos níveis séricos de malondialdeído (p<0,05) e aumento da quantidade de fibras elásticas na parede carotídea dos ratos SHR e SHR-sp. Conclusão: A suplementação suprafisiológica de bcaroteno não causou efeitos tóxicos, apresentou resposta positiva na modulação da pressão arterial e diminuição na concentração sérica de malondialdeído. Não foram encontradas alterações morfológicas significativas nos grupos estudados, exceto um aumento no número de fibras elásticas da camada muscular carotídea sugerindo elastose nos ratos SHR e SHR-sp. .

ABSTRACT

PURPOSE: To analyze the small intestinal mucosa ultrastructure, and to characterize the enterocyte lesion severity caused by mechanical intestinal obstruction combined or not with an ischemia of the mesenteric marginal vessels arch. METHODS: It was used 47 Wistar rats divided into 4 groups as follows: Group 1- Control rats (C), Group 2- sham rats (S), Group 3- rats submitted to intestinal obstruction excluding marginal vessel (OEV), Group 4- Intestinal obstruction including marginal vessels (OIV). Rats of groups 3 and 4 were allotted into two subgroups for the removal of small intestinal tissue samples, one at the proximal (P), and the other at the distal (D) segments from the obstruction site. Samples of groups 2, 3, 4 were obtained 24, 48, and 72 hours after post operation care. Small intestinal tissue samples of group 1 were excised following laparotomy. Imaging in Light and Transmission Electronic Microscopy were used for morphological and morphometric studies. The results were analyzed by using the ANOVA and Newman-Keuls tests. RESULTS: No irreversible lesion was observed. In the 24 hours microvilli volume of group 3 turned down at the proximal site henceforth enlarging very slowly within the next 72 hours. At the distal site significant microvilli shrinkage was observed up to 48 hours. Then they recovered their volume after 72 hours. In the 24 hours microvilli volume of group 4 grew twice in comparison with the microvilli of group 1 rats but after 72 hours there was drastic volume shrinkage, shape alterations, and severe flatness, especially in the distal segments of the obstruction site. CONCLUSIONS: Terminal ileum mechanical obstruction with mesenteric marginal arch ischemia led to reversible ultrastructural alterations after 72 hours, and the injury is proportional to the persistence of the obstructive process. Furthermore the mesenteric vessels of the marginal arcade play an important role in the maintenance of mucosal integrity, when such obstructive disorder is present.

OBJETIVO: Analisar as alterações ultra-estruturais da mucosa do intestino delgado e caracterizar a severidade das lesões causadas por uma obstrução intestinal mecânica, associada ou não a isquemia da arcada marginal mesentérica. MÉTODOS: Foram utilizados 47 ratos, da linhagem Wistar, distribuídos em quatro grupos, da seguinte forma: Grupo 1 - Controle (C), Grupo 2- Simulação (S), Grupo 3- Ratos com obstrução intestinal sem inclusão de vaso marginal (OEV), Grupo 4 - Obstrução intestinal com inclusão de vaso marginal (OIV). Os animais dos grupos 3 e 4 foram redistribuídos em dois subgrupos com coleta de amostras do intestino delgado, à montante (P) e à jusante (D) do ponto de obstrução. Nos grupos 2, 3 e 4, as amostras foram colhidas com 24, 48 e 72 horas de pós-operatório. No grupo 1, este material foi retirado após laparotomia. Realizaram-se estudos morfológicos e morfométricos dos microvilos através das Microscopias Óptica e Eletrônica de Transmissão. Os resultados foram analisados mediante os testes estatísticos de ANOVA e Newman-Keuls. RESULTADOS: Não foram observadas lesões irreversíveis. No grupo 3 com 24 horas, o volume dos microvilos diminuiu, à montante, com discreto aumento em 72 horas. Á jusante, houve redução significante até 48 horas, com recuperação em 72 horas. No grupo 4, o volume dos microvilos quase dobrou em relação ao grupo 1, com 24 horas, mas reduziu-se, drasticamente, em especial à jusante, com 72 h de evolução, apresentando deformidade e achatamento severos, achados estes estatisticamente significantes. CONCLUSÕES: A obstrução intestinal mecânica do íleo terminal, associada ou não a isquemia da arcada mesentérica marginal, causa alterações ultra-estruturais reversíveis dos enterócitos, cuja gravidade é diretamente proporcional à duração do processo mórbido obstrutivo, até 72 horas de evolução. Aduz-se que, os vasos mesentéricos da arcada marginal exercem um papel relevante na preservação da mucosa intestinal, na ...

ABSTRACT

OBJETIVO: estudar os critérios morfológicos e imunoistoquímicos relacionados ao prognóstico dos tumores estromais gastrointestinais. MÉTODOS: o estudo foi retrospectivo de 42 casos de tumor estromal gastrointestinal (GIST). Vinte e cinco casos foram obtidos no arquivo do Serviço de Anatomia Patológica do Hospital Universitário Gaffrée e Guinle e os outros dezessete, do Serviço de Anatomia Patológica do Hospital Universitário Clementino Fraga Filho. RESULTADOS: de acordo com a análise univariada os tumores maiores que 5 cm, com número de mitoses maior que 5/50 CGA, presença de necrose, de alto risco, revelaram significância em relação a redução da sobrevida (p= 0,017, 0,010, 0,001 e 0,016, respectivamente). Os outros fatores analisados (subtipo histológico, topografia e imunofenótipo) não mostraram significância. CONCLUSÃO: os resultados confirmam a utilidade do grau de risco, do tamanho tumoral, do índice mitótico e da necrose como fatores preditores do comportamento biológico dos tumores estromais gastrointestinais.


OBJECTIVE: study the morphologic criteria and immunohistochemical related with the prognostic of the gastrointestinal stromal tumors. METHODS: the study was retrospective of 42 cases of gastrointestinal stromal tumor (GIST). Twenty-five cases were obtained in the file of the Services of Pathological Anatomy of the Hospital Gaffrée and Guinle and the other 17 of Pathological Anatomy of the Hospital Clementino Fraga Filho. RESULTS: in agreement with the univaried analysis, the tumors largest than 5 cm, with mitoses number greater than 5/50 CGA, presence of necrosis, high risk, revealed significance with regarding the reduction of the survival (P = 0.017, 0.01, 0.001 and 0.016, respectively). The other analyzed factors (histological subtype, topography and imunophenotype) they didn't show significance. CONCLUSION: the results confirm the usefulness of the risk degree, the tumorous size, the mitotic index and the necrosis as predictor factors of the biological behavior of the gastrointestinal stromal tumors.

ABSTRACT

OBJECTIVE: To establish a connection between infection by the human papilloma virus (HPV) and development of malignant (squamous cell carcinoma) and benign lesions (epithelial hyperplasia papillomatosis and papilloma) of the oral cavity and oropharynx. METHOD: A retrospective study of 66 blades and paraffin blocks with biopsy tissue fixed with formalin. This material, collected in 2002, refers to a group of 44 men (66.7%) and 22 women (33.3%) with ages ranging from 11 to 100 years, with confirmed diagnoses of squamous cell carcinoma in 38 cases, of epithelial hyperplasia papillomatosis in 20 cases and of papillomas in 8 cases. This material was analyzed by immunohistochemistry and the presence of viral DNA in the biopsy samples was determined. RESULTS: Presence of the viral DNA (HPV) in 16 of the 38 cases of carcinoma (42.5%), 19 in 20 cases of hyperplasia (95%) and 8 in 8 cases of papilloma (100%) was detected. CONCLUSION: The samples in this study show the predominant incidence of the HPV in the epithelial hyperplasia papillomatosis and papilloma in relation to squamous cell carcinoma. This last lesion, on the other hand, did not show statistical correlation to the HPV.

ABSTRACT

O objetivo deste trabalho é estabelecer a relação entre a infecção pelo vírus do papiloma humano (HPV) e o desenvolvimento de lesões malignas (carcinoma epidermóide) e benignas (hiperplasia epitelial papilomatosa e papiloma) de cavidade bucal e orofaringe. MÉTODOS: Estudo retrospectivo de 66 lâminas e blocos de parafina com tecido biopsiado e fixado com formalina. Esse material, colhido no ano de 2002, refere-se a uma casuística de 44 homens (66,7 por cento) e 22 mulheres (33,3 por cento) com idades que variavam entre 11 e 100 anos. O diagnóstico foi confirmado em 38 casos de carcinoma epidermóide, 20 casos de hiperplasia epitelial papilomatosa e oito casos de papilomas. Utilizamos a imunohistoquímica para analisar este material e determinar a possível presença do DNA viral nas amostras citadas. RESULTADOS: Detectamos a presença do DNA viral (HPV) em 16 dos 38 casos de carcinoma (42,5 por cento), 19 em 20 casos de hiperplasia (95 por cento) e em todos os oito casos de papilomas (100 por cento). CONCLUSAO: Este estudo demonstrou que as lesões papilomatosas e hiperplásicas da boca e orofaringe estão associadas ao HPV, ao contrário do carcinoma espinocelular que não apresentou correlação estatística significante com este agente infeccioso.

ABSTRACT

Mycobacterial pseudotumor (MP) is a rare pathologic presentation of both Mycobacterium tuberculosis and non-tuberculous mycobacterial disease, hitherto reported to occur only in immunosuppressed patients with or without human immunodeficiency virus infection. This lesion shares close pathologic resemblance to certain mesenchymal neoplasms, particularly Kaposi's sarcoma (KS), from which it must be properly differentiated due to distinct prognosis and therapy. We report a case of MP obliterating the lumen of the appendix vermiformis in a 34-years-old patient who died of complications of AIDS at our hospital in Rio de Janeiro. A total of 24 cases of MP (including our patient) have been described in the literature. MP has been found especially in lymph nodes, but extranodal lesions have been described in the skin, spleen, lung, bone marrow, brain and, in our patient, the appendix vermiformis. We offer a review of the other 23 published case reports of MP in both HIV-infected and uninfected patients and discuss the pathologic features that differentiate MP from KS.

ABSTRACT

The course of human immunodeficiency virus infection and the acquired immunodeficiency syndrome can be complicated by a variety of endocrine abnormalities. This article describes the findings of a prospective study of 100 AIDS patients with thyroids compromised by infectious agents or neoplastic disorders from a time period before the use of highly active antiretroviral regimens. A wide range of bacterial, fungal, viral, and neoplastic disorders were observed. Mycobacetrium tuberculosis was recorded in 23 percent of the patients, cytomegalovirus in 17 percent, Cryptoccocus in 5 percent, Mycobacterium avium in 50 percent, Pneumocystis in 4 percent, and other bacteria or fungi in 7 percent. Kaposi's sarcoma was recorded in 2 percent of patients and occult papillary carcinoma in 4 percent. Four patients had dual infections of the thyroid. The mean weight of the thyroid was lower than normal, and 1 case of thyroid follicular atrophy is presented. A review of the medical literature on thyroid disorders in HIV-infected patients is included. Physicians caring for HIV patients should be aware of the possibillity of thyroid dysfunction in their patients.
