Vaginal reconstruction using a gluteal transposition flap after abdominoperineal excision for anorectal malignancy.

The purpose of this study is to present and evaluate a surgical method using gluteal flap for combined perineal and vaginal reconstruction after abdominoperineal excision (APE) with partial vaginectomy for anorectal malignancy. The method is a two-centre study of consecutive patients undergoing APE including partial vaginectomy for anorectal tumours, with immediate combined perineal and vaginal reconstruction using gluteal flaps. Follow-up data were retrieved via retrospective review of medical records, questionnaires and gynaecological examinations.

Differential expression of cysteinyl leukotriene receptor 1 and 15-lipoxygenase-1 in non-Hodgkin lymphomas.

Background: Arachidonic acid metabolites have been suggested to play an important role in carcinogenesis. We have recently reported that the cysteinyl leukotriene receptor 1 (CysLT1) and 15-lipoxygenase-1 (15-LO-1) are expressed by the malignant Hodgkin Reed-Sternberg cells of Hodgkin lymphoma and certain Hodgkin lymphoma cell lines, and that these cells convert arachidonic acid to the novel proinflammatory eoxins.

Materials And Methods: The expression of the CysLT1 receptor and 15-LO-1 was investigated in a broad range of non-Hodgkin lymphomas (NHLs) by immunohistochemistry.
