Cutaneous metastasis of vaginal carcinoma is extremely rare. So far, the total number of reported skin metastasis of vaginal carcinoma is only one. We present another case with an unusual manifestation of vagina carcinoma metastasis: skin metastasis presenting as a leg ulcer on the lower leg.  相似文献

Thirty patients with Philadelphia chromosome-positive lymphoid (20 patients) or undifferentiated (ten patients) chronic myelogenous leukemia in blast crisis were treated with 0.4 mg of vincristine by continuous intravenous infusion (CIV) daily for 4 days; (doxorubicin) 12 mg/m2 of Adriamycin (Adria Laboratories, Columbus, OH) by continuous intravenous infusion daily for 4 days; and 40 mg of decadron daily on days 1 through 4, 9 through 12, and 17 through 20 (VAD). Course 2 was given starting on day 24 with the addition of cyclophosphamide 1 g/22. Overall nine patients achieved complete remission (30%) and three attained a partial remission (10%), for an overall response rate of 40%. Four patients expired during induction whereas 14 had resistant disease. Response rate was significantly higher for patients with lymphoid compared to undifferentiated morphology (55% versus 10%; P = 0.05). In lymphoid blast crisis, Calla-positive disease was associated with a higher response rate compared to Calla-negative disease (75% versus 25%; P = 0.08). Eleven patients developed infections, and seven had fever without documented infections. The median overall survival was 29 weeks. Median survival was 43 weeks for patients achieving complete remission and 20 weeks for those with resistant disease. Remission duration was 39 weeks. After primary and salvage therapy, nine patients are alive, six of them in continuous remission for 19+ to 112+ weeks. The authors conclude that VAD chemotherapy is an effective regimen with acceptable toxicity in patients with lymphoid blast crisis especially those with Calla-positive disease. Alternate induction regimens for undifferentiated disease and for maintenance therapy are currently being investigated.  相似文献

Localization of a gene for otosclerosis to chromosome 15q25-q26   总被引:5,自引:0,他引:5  
Among white adults otosclerosis is the single most common cause of hearing impairment. Although the genetics of this disease are controversial, the majority of studies indicate autosomal dominant inheritance with reduced penetrance. We studied a large multi- generational family in which otosclerosis has been inherited in an autosomal dominant pattern. Five of16 affected persons have surgically confirmed otosclerosis; the remaining nine have a conductive hearing loss but have not undergone corrective surgery. To locate the disease- causing gene we completed genetic linkage analysis using short tandem repeat polymorphisms (STRPs) distributed over the entire genome. Multipoint linkage analysis showed that only one genomic region, on chromosome 15q, generated a lod score >2.0. Additional STRPs were typed in this area, resulting in a lod score of 3.4. STRPs FES (centromeric) and D15S657 (telomeric) flank the 14. 5 cM region that contains an otosclerosis gene.   相似文献

There is increasing evidence that immunological mechanisms play a role in the pathogenesis and pathophysiology of endometriosis. It was therefore of interest to study interleukin-8 (IL-8), a chemokine, in the peritoneal fluid and peripheral blood of women undergoing laparoscopic procedures. The presence and concentrations of IL-8 in relation to endometriosis, infertility and abdominal pain were evaluated. Samples of peritoneal fluid (n = 49) and peripheral blood (n = 50) were obtained from 50 consecutive patients undergoing laparoscopic surgery for various gynaecological indications (abdominal pain, infertility, sterilization). IL-8 was present in the peritoneal fluid of most women (87%). The concentration of IL-8 in the peritoneal fluid was higher in women with endometriosis compared to women without (P = 0.02). This difference was more pronounced in early (stage 1) endometriosis (P = 0.001). IL-8 concentrations in the peritoneal fluid were also higher in women with early endometriosis compared to women with later stages of the disease (P = 0.003). Peripheral blood concentrations did not correlate with peritoneal fluid concentrations of IL-8 and/or the presence of endometriosis. We conclude that IL-8 is an important factor that may contribute to the pathogenesis of endometriosis possibly by promoting neovascularization. This information can be a guide in the development of new therapeutic approaches for the treatment of endometriosis.   相似文献
