Lymph node metastasis in nasal vestibule cancer: A review

Item does not contain fulltextBACKGROUND: Squamous cell carcinoma of the nasal vestibule (SCCNV) is an uncommon malignancy. Our purpose is to define the incidence of simultaneous and delayed regional metastasis in SCCNV according to the available literature. METHODS: Articles discussing SCCNV and addressing the issue of regional lymph node metastases were reviewed. CONCLUSION: SCCNV is an uncommon form of cancer, possibly originating in the mucocutaneous junction. The incidence of lymph node metastasis is variably reported. The data in the literature do not provide a solid basis for recommendations on elective treatment of the neck. Thorough examination of the neck is recommended, preferably with modern imaging techniques. (c) 2010 Wiley Periodicals, Inc. Head Neck, 2010

Membrana amniótica preservada em glicerina no reparo de feridas cutâneas de membros locomotores de eqüinos Equine amniotic membrane preserved in glycerin in reparing the equine limbs cütaneous wounds

Neste estudo experimental, avaliou-se o uso de membrana amniótica eqüina preservada em glicerina 98%, à temperatura ambiente, em feridas com cura por segunda intenção, nos membros locomotores de eqüinos. Foram provocadas cirurgicamente feridas de 9,6cm² na face lateral da articulação metacarpo-falangeana, face medial do terço proximal do metacarpo e face lateral do terço médio do metatarso de ambos os membros locomotores de cinco eqüinos adultos, perfazendo total de trinta feridas. Foram constituídos dois grupos experimentais com quinze feridas cada, sendo um destes grupos tratado com membrana amniótica, e o outro, grupo controle, tendo recebido apenas gaze umidecida em solução fisiológica. Os curativos foram trocados a cada 48horas, tendo sido a membrana amniótica e a gaze umidecida substituídas. Em todas as feridas foram mensurados a área, o grau de secreção, a formação de tecido de granulação exuberante e o tempo para a epitelização se completar. Realizou-se também exame bacteriológico e histopatológico em um grupo de feridas, tratadas e controle. Na membrana amniótica, fez-se determinação bioquímica de proteínas e identificação de fator de crescimento de fibroblasto. Em todas as feridas tratadas, observou-se: menor tempo para cicatrização, menor formação de tecido de granulação exuberante, menor incidência de bactérias patológicas e menor aumento na área total.<br>In the present experimental study, the use of the equine amniotic membrane preserved in glvcerol 98%, at room temperature, in wounds with secound intention healing of equine limbs were evaluated. Surgical wounds of the size of 9.6cm² were made on the fetiock joint, medial aspect of the proximal third of the metacarpus and lateral aspect of the medium third of the metatarsus ofboth limbs offive adult horses, making a total of thirty wounds. Two experimental groups were made with fifteen wounds in each group, where one of these groups was treated with amniotic membrane, and the other, the control group, treated only with a damp gauze changed every 48 hours. In all the wounds the procedure was to evaluate the measurement of the área, degree of secretion, development of exuberant granulation tissue and the complete time of epitheliazation. Bacteriologic and histopatologic exams were made in a sample of the treated and contrai groups. The biochemical determination of proteins and the identification of fibroblastic growth factor were realized in the amnionic membrane. In all the treated wounds were observed shorter healing time, less formation of exuberant granulation tissue, smaller incidence of pathogenic bacterias and a smaller increase of the wound area
