Uso do contraste oral negativo em exames de colangiografia por ressonância magnética

OBJETIVO: Realizamos estudo prospectivo das vias biliares e pancreáticas através de colangiografia por ressonância magnética, com a utilização de meio de contraste oral negativo. Os nossos objetivos foram verificar se este novo meio de contraste melhora a visualização das vias biliar e pancreática, além de identificar a freqüência de efeitos colaterais ao contraste e sua aceitação pelo paciente. MATERIAL E MÉTODO: Quinze voluntários (oito homens e sete mulheres) com idades variando entre 18 e 54 anos (média de 29 anos), sem queixas ou cirurgias abdominais, foram submetidos a colangiografia por ressonância magnética. Foram realizadas duas seqüências colangiográficas em apnéia, antes e cinco minutos após a ingestão de 300 ml de contraste oral negativo. Os exames foram realizados em equipamento operando a 1,0 T. RESULTADOS: Setenta e três por cento dos voluntários consideraram o gosto ruim ou muito ruim, sugerindo uma aceitação discutível; 27% dos voluntários apresentaram náuseas; 20%, cólicas; 14%, azia ou parestesia labial; e 7%, diarréia. A visualização da via biliar extra-hepática foi considerada melhor após o contraste oral negativo em 9/15 voluntários (60%) e do ducto pancreático principal em todos os cinco em que havia interposição de alças. CONCLUSÃO: O contraste oral negativo melhora a visualização dos ductos hepatocolédoco e pancreático principal em exames de colangiografia por ressonância magnética, apesar da baixa aceitação e dos seus efeitos colaterais.

OBJETIVO: Verificar se o uso do laser de InGaAlP com comprimento de onda de 685 nm pode reduzir a incidência de xerostomia, gravidade da mucosite oral e da dor associada à mucosite em pacientes portadores de câncer de cabeça e pescoço submetidos a radioterapia. MATERIAIS E MÉTODOS: Sessenta pacientes portadores de carcinoma de cabeça e pescoço foram submetidos a radioterapia com dose diária de 1,8 a 2,0 Gy e dose final de 45 a 72 Gy. O volume salivar foi medido nos dias um, 15, ao final do tratamento e após 15 e 30 dias, e a mucosite oral em avaliações semanais. Vinte e nove pacientes se submeteram a radioterapia sem laser e 31 foram submetidos a radioterapia e laser com dose diária de 2 joules/cm² em pontos pré-determinados da mucosa oral e glândulas parótida e submandibular. RESULTADOS: No grupo submetido a radioterapia e laser, a incidência de mucosite (p < 0,001) e dor (p < 0,016) foram significativamente menores e o volume salivar se manteve maior (p < 0,001) durante e após o tratamento. CONCLUSÃO: Os pacientes submetidos à associação de radioterapia e laser tiveram menor incidência de xerostomia, mucosite oral e dor quando comparados ao grupo de radioterapia sem laser, com resultados com significância estatística.

Hybrid treatment of penetrating aortic ulcer

AbstractPenetrating atherosclerotic aortic ulcer is a rare entity with poor prognosis in the setting of acute aortic syndrome. In the literature, cases like the present one, located in the aortic arch, starting with chest pain and evolving with dysphonia, are even rarer. The present report emphasizes the role played by computed tomography in the diagnosis of penetrating atherosclerotic ulcer as well as in the differentiation of this condition from other acute aortic syndromes. Additionally, the authors describe a new therapeutic approach represented by a hybrid endovascular surgical procedure for treatment of the disease.
