cervicouterine cancer

Víctor Manuel Vargas-Hernández, Víctor Manuel Vargas-Aguilar, José María Tovar-Rodríguez
Cervico-uterine cancer screening with cytology decrease incidence by more than 50%. The cause of this cancer is the human papilloma virus high risk, and requires a sensitive test to provide sufficient sensitivity and specificity for early detection and greater interval period when the results are negative. The test of the human papilloma virus high risk, is effective and safe because of its excellent sensitivity, negative predictive value and optimal reproducibility, especially when combined with liquid-based cytology or biomarkers with viral load, with higher sensitivity and specificity, by reducing false positives for the detection of cervical intraepithelial neoplasia grade 2 or greater injury, with excellent clinical benefits to cervical cancer screening and related infection of human papilloma virus diseases, is currently the best test for early detection infection of human papillomavirus and the risk of carcinogenesis...

BACKGROUND AND AIMS: An assessment was performed of the quality of Pap readings in 19 cytology laboratories (CLs) in Mexico from the Cervical Cancer Screening Program. METHODS: Nine CLs were affiliated with the Health Ministry (SSA), and ten were affiliated with the Mexican Social Security Institute (IMSS). Two sets of 200 cervical cytology specimens were prepared, one set for each institution. Fourteen percent of the specimens were positive and six were inappropriate for diagnosis (3%)...

Diverse steroidal compounds have shown antiproliferative activity on certain tumor cell lines; however, their complete role on cancer cells has not been extensively established since the research is quite recent. Hence, deeper study in this field is required. Due to the importance of selenium in animal and human health; herein, we report the synthesis, characterization, and biological evaluation of two novel 22-oxo-26-selenocyanocholestanic steroids on cervicouterine cancer cells and non-tumor cells. The title compounds were straightforward prepared from diosgenin and hecogenin in excellent overall yields...

The pyometra is a rare condition, with an incidence of less than 1%. In patients with cervical cancer, spontaneous rupture of pyometra manifests as a generalized peritonitis, which is extremely rare, in the literature only seven cases are described. This paper reports the case of a patient with a history of postmenopausal vaginal bleeding one month before her admission to the hospital; she attended because of acute abdomen. The CT scan reported air in the abdominal cavity and the uterus with air at the periphery, so she underwent an exploratory laparotomy in which purulent material was found with two perforations in the uterine fundus...

The synthesis of glucosamine derivatives of the steroidal sapogenins diosgenin and hecogenin using the N-phthaloyl protected trichloroacetimidate of d-glucosamine as donor and TMSOTf as promoter is reported. The corresponding glycoconjugates were transformed into their acetamido derivatives and the hydrochloride salt (from diosgenin) and tested against HeLa, CaSki, and ViBo cervicouterine cancer cells. These compounds showed low cytotoxicity values on tumor cells and human lymphocytes, indicating that the main cell death process is presumably not necrosis...

The synthesis and biological evaluation of the new cholestane glycoside (25R)-3β,16β-diacetoxy-22-oxocholest-5-en-26-yl β-d-glucopyranoside starting from diosgenin is described. This compound showed selective antiproliferative activity against CaSki, ViBo, and HeLa cervicouterine cancer cells. Its effect on the cell-cycle was determined. The cytotoxic effects of the title compound on cervicouterine cancer cell lines and human lymphocytes indicate that the main cell death process is not necrosis; hence it is not cytotoxic...

BACKGROUND: to determine the quality of a prompt cervical cancer detection program (TDC CC) according to the indicators for prevention and diagnosis. METHODS: cross-sectional and comparative study conducted in four primary care units. We selected 400 patients who attended preventive services to participate in the study of cervical cytology (Pap). The evaluation of the Program of TDC CC was obtained by the degree of fulfillment of quality and productivity outlined by an institutional program...

BACKGROUND: It has been considered the incidence and the prevalence of the disease of sexual transmission with base in the different data banks. Unfortunately, each of these sources has limitations. OBJECTIVE: To evaluate annual prevalence of genital condiloma acuminate in the women who go to opportune detection of cervicouterine cancer. MATERIAL AND METHOD: Study realized in a first level of attention, the Zaragoza clinic of the System of Collective Transport Metro of Mexico City; of January of the year 2000 to June of year 2009...

The synthesis of the new glycoside (25R)-3β,16β-diacetoxy-12,22-dioxo-5α-cholestan-26-yl β-D-glucopyranoside starting from hecogenin is described. This compound showed anti-cancer activity against cervicouterine cancer cells HeLa, CaSki and ViBo in the micromolar range. Its effect on cell proliferation, cell cycle and cell death is also described. The cytotoxic effect of the title compound on HeLa, CaSki and ViBo cells and human lymphocytes was evaluated through the LDH released in the culture supernatant, indicating that the main cell death process is not necrosis; the null effect on lymphocytes implies that it is not cytotoxic...

INTRODUCTION: Postradiation proctopathy (PP) is a major complication in patients who receive radiotherapy for cancer. Medical treatments of this entity are unsatisfactory. Argon plasma coagulation (APC) had been shown to be successful with low complications. The aim was to describe our experience with APC in the management of PP. METHODS: We conducted a retrospective analysis of electronic- and paper-based records of patients with PP managed with APC. RESULTS: Nineteen patients with PP were included, nine were women...

BACKGROUND: Cervicouterine cancer is one of the main public health problems in Mexico. Several problems related to the low effectiveness of the Program of Opportune Detection of Cervicouterine Cancer have been identified, among them: low cover of the disease detection and absence of quality control in the detection, diagnosis and treatment of it. In Mexico the quality control problem in cytology has been taken with success, but the opposite occurs with colposcopy practice. For that reason this service is overused by patients with low risk cancer and is not accessible for the high risk population...

Bioactivities present in three honeybee royal jelly (RJ) protein fractions were screened for diverse in vitro model systems. RJCP, a RJ crude protein extract, stimulated cell growth of Tn-5B1-4 insect cells inducing 6.5 population doublings per mg of protein added to culture medium, meanwhile fetal bovine serum, the usual growth supplement, gave rise only to 2.55 population doublings. RJCP, as well as the fractions RJP30 and RJP60 obtained by precipitation with ammonium sulfate, also affected Tn-5B1-4 cell shape and stimulated adhesion of these cells to the substrate...

BACKGROUND: In locally advanced pelvic cancer, tumor fixation to the bony pelvis is regarded as unresectable and often inoperable. Few data exist regarding the futility or utility of pelvic exenteration with en bloc resection of involved portions of the bony pelvis. METHODS: Thirty-four of 625 patients undergoing radical pelvic procedures had an en bloc resection of pelvic organs with portions of the bony pelvis. There were 19 female and 15 male patients, and the median age was 59 years...
