Background We designed a prospective study to assess the likelihood that early lesions presenting as mammographic calcifications could be accessed for cytological diagnosis by ductal lavage (DL).Methods Consenting women with calcifications (Breast Imaging Reporting and Data System 4 or 5) underwent DL of fluid-yielding ducts (FYDs) before stereotactic core or excisional biopsy. The DL catheter was used to inject .2 to 1 mL of Isovue 300 into the duct to determine whether the FYD corresponded to the duct containing calcifications (designated overlap). Additional FYDs were injected, if possible, until overlap was identified. DL cytology was compared with histology.Results Twenty women were enrolled (mean age, 54.2 years); the mean size of the calcification-bearing area was 190 mm2. The histological findings were as follows: 1 invasive cancer, 9 ductal carcinomas-in-situ (DCIS), 5 atypical hyperplasias, and 5 usual hyperplasias or fibrocystic changes. Four women had no FYD. In 15 women who underwent DL and ductography, overlap of dye and calcifications was seen in 4 (27%): 1 fibrocystic change, 1 hyperplasia, 1 atypical hyperplasia (cytological diagnosis mildly atypical), and 1 DCIS (cytological diagnosis benign). Of the remaining 8 DCIS lesions, 4 had no nipple aspiration fluid, 1 showed extravasation, and 3 were lavaged but the duct did not overlap.Conclusions These results are consistent with data from women undergoing mastectomy for larger invasive cancer and DCIS and show that cancer-containing ducts do not yield nipple fluid in most cases.Published by Springer Science+Business Media, Inc. © 2005 The Society of Surgical Oncology, Inc. 相似文献

The Global Polio Eradication Initiative (GPEI) promised eradication of polio by the year 2000 and certification of eradication by 2005. The first deadline is already a matter of history. With the reporting of polio cases in 2004, the new deadline for polio eradication by 2004 is postponed further. This article seeks to argue that the scientific and technical bodies spear-heading the GPEI, including the WHO, UNICEF, and the U.S. Centers for Disease Control, have formulated a conceptually flawed strategy and that it is not weak political will that is the central obstacle in this final push for global eradication. The validity of the claims of "near success" by the proponents of the GPEI is also examined in detail. By taking India as a case study, the authors examine the achievements of the GPEI in nine years of intense effort since 1995. They conclude that the GPEI is yet another exercise in mismanaging the health priorities and programs in developing countries in the era of globalization. 相似文献

Background/Purpose Laparoscopic cholecystectomy is the procedure of choice for patients with symptomatic cholelithiasis. This procedure is contraindicated in patients with gall-bladder cancer (GBC) because of fear of dissemination of the disease. One of the findings raising the suspicion of GBC is a thick-walled gallbladder (TWGB).Methods A prospective study of patients with TWGB was done over a period of 10 months at a tertiary-level referral hospital in northern India. We studied the clinical profiles, investigations (ultrasound [US] and computerized tomography [CT]) and management plans in these patients.Results A total of 60 patients were included in the study. After cholecystectomy, histopathology of gallbladders showed GBC in 2 (3.3%) patients. The remaining 58 patients had chronic cholecystitis, of whom 28 (48%) had xanthogranulomatous variant chronic cholecystitis. Cholecystectomy by the laparoscopic method was attempted in 46 (77%) patients and by open technique in the remaining 14 (23%) patients. Laparoscopic cholecystectomy was successful in 40 of the 46 (87%) patients in whom it was attempted. Obscure anatomy, suspicion of GBC, and bile duct injury were the causes of conversion, in the remaining 13% (6/46). None of the 11 patients who had a CT examination because of clinical or US suspicion of malignancy turned out to have GBC at final histology. Both the cases of GBC in this study were incidental findings on final histopathology.Conclusions Laparoscopic cholecystectomy can be successfully performed in the majority of patients with diffuse TWGB, with appropriate selection. There is, however, an increased chance of conversion to open cholecystectomy in these patients. If there is an intraoperative suspicion of GBC, early conversion to open cholecystectmy and frozen section/imprint cytology will help to decide the further treatment during surgery. 相似文献

Chryseobacterium meningosepticum is a Gram-negative bacillus historically associated with meningitis and sepsis in premature neonates. Clinicians should suspect this organism when Gram-negative bacilli are seen on Gram-stain and culture, particularly in immunocompromised patients, and in cases of disrupted host tissue integrity. We report the first case of septic arthritis due to this organism. 相似文献

Enhancement of paclitaxel-induced microtubule stabilization, mitotic arrest, and apoptosis by the microtubule-targeting agent EM012 总被引:3,自引:0,他引:3
EM012, a semisynthetic phthalideisoquinoline alkaloid, has been recently found to target microtubules and possess anti-cancer activity. In this study, we evaluated the effects of EM012 in combination with the classic microtubule-targeting agent paclitaxel. Our results demonstrated that EM012 enhanced the anti-proliferative activity of nanomolar concentrations of paclitaxel in human breast cancer (MCF7), prostate cancer (DU145), and non-small-cell lung cancer (A549) cells. Further studies revealed that EM012 increased the ability of nanomolar concentrations of paclitaxel to induce mitotic arrest and apoptosis, without affecting microtubule polymerization. In contrast, when micromolar concentrations of paclitaxel were used, EM012 promoted paclitaxel-induced microtubule polymerization both in vitro and in cultured cells. Nevertheless, EM012 enhanced the ability of nanomolar concentrations of paclitaxel to stabilize microtubules, as indicated by increased tubulin acetylation. Our results therefore suggest a therapeutic potential of EM012/paclitaxel combination in the management of human cancer and provide mechanistic insights into the combined effects of these two microtubule-targeting agents. 相似文献

An unusual case of massive cystic degeneration in an uterine leiomyoma measuring 21 cm in diameter, in a 40 year old female is being presented. It was diagnosed as a cystic adnexal tumor on ultrasonogram. Interlacing bundles of smooth muscle were identified in the cyst wall, which was confirmed on special stains. The differential diagnoses considered in this case are discussed. To the best of our knowledge, this is the largest cystic degeneration in an uterine leiomyoma reported in the literature. 相似文献
