New method: Are tumor markers in vaginal-washing fluid significant in the diagnosis of primary ovarian carcinoma?

OBJECTIVE: Ovarian cancer is the seventh most common cancer in women worldwide, with nearly a quarter of a million women diagnosed every year. The serum tumor markers cancer antigens CA 125, CA 19-9, and carcinoembryonic antigen (CEA) are potentially of clinical value for the diagnosis of ovarian cancer. A diagnostic tool that is noninvasive, simple to perform, and specific is needed to predict primary ovarian cancer. The purpose of this study was to evaluate the diagnostic sensivitity and specificity of vaginal-washing tumor markers CA 125, CA 19-9, and CEA for diagnosis of primary ovarian cancer. MATERIALS AND METHODS: In the current prospective study, 30 patients with advanced primary ovarian cancer and 30 patients with benign ovarian cysts were enrolled. The vaginal-washing fluid samples were obtained the day before surgery and were immediately centrifuged and stored at -80 degrees C until analysis. Measurements of CA 125, CA 19-9, and CEA were determined using fully-automated chemiluminescent microparticle immunoassays. RESULTS: The vaginal fluid concentrations of CA 125, CA 19-9, and CEA in patients with primary ovarian carcinoma were significantly higher (p < 0.001) compared to those in patients with benign adnexal masses (p < 0.001). In the ROC curve analysis, the optimal cut-off values for the detection of primary ovarian cancer were >295 for CA 125 (p < 0.001), > 101 for CA 19-9 (p < 0.001), and >135 for CEA (p < 0.001). CONCLUSION: Vaginal-washing tumor markers CA 125, CA 19-9, and CEA are simple, noninvasive, and reliable diagnostic tests for the detection of primary ovarian cancer.

Uterine artery ligation at the beginning of total laparoscopic hysterectomy reduces total blood loss and operation duration.

The purpose of this study was to compare the feasibility, blood loss, duration of surgery and complications between patients in whom both uterine arteries were ligated by surgical clips and cut using a 5-mm ligature at the beginning of total laparoscopic hysterectomy (TLH) and patients in whom uterine arteries were not ligated at the beginning of TLH. In our prospective study, a total of 60 women underwent TLH. Uterine artery ligation (UAL) was done at the beginning of the procedure. Women were divided into TLH + UAL (n = 30) and TLH (n = 30) groups. In TLH group, TLH was done without ligating the uterine arteries at the beginning of the procedure. In TLH + UAL group, TLH was done with ligation of both uterine arteries at the beginning of the procedure. The mean operating time was longer for the TLH group (99.16 ± 7.01) than TLH + UAL group (63.27 ± 7.16). The median total blood loss was higher in TLH group (109.38 ± 33.03 mL) than TLH + UAL group (47.50 ± 8.12 mL). UAL at the beginning of TLH is a technically feasible procedure. It reduces the total blood loss and decreases the time taken for the procedure and length of hospital stay.

Does gestational diabetes result in cochlear damage?

BACKGROUND: Glucose metabolism has a significant impact on inner-ear physiology. Therefore, hearing may be affected in gestational diabetes. METHOD: A matched case-control study was performed to evaluate 27 patients with gestational diabetes and 31 non-diabetic pregnant women with similar demographic characteristics. A medical history was taken for each participant, and otological inspections and high-frequency audiometry tests were performed. RESULTS: There were no significant differences in average pure tone air-bone hearing thresholds between the groups (p > 0.05). However, evaluation of high-frequency hearing thresholds indicated significantly increased auditory thresholds at 10 kHz and 12 kHz for right ears and at 8, 10, 12 and 14 kHz for left ears in the gestational diabetes group (p < 0.001). CONCLUSION: An investigation into cochlear damage in gestational diabetic patients showed significant high-frequency hearing loss. Further studies are needed to validate these findings in different ethnic groups and geographical populations.
