Article: Etanercept causes regression of endometriotic implants in a rat model.
[show abstract] [hide abstract]
ABSTRACT: To determine the effects of etanercept (anti-TNF-α) on surgically induced endometriosis in a rat model. This is a prospective, randomized, controlled, experimental study that was carried out at the Experimental Research Center of Yeditepe University (YUDETAM). Thirty female nonpregnant, nulligravid Wistar-Hannover albino rats were used. The summary of the technique: surgical induction of endometriosis, administration of estrogen for 2 weeks, and laparotomy; administration of etanercept for 2 weeks following the induction of endometriosis and laparotomy; administration of estrogen for 2 weeks and necropsy. The volume and histopathological scores of the endometriotic foci were evaluated. One-hundred twenty uterine horns were implanted in 30 rats. Endometriosis was completely formatted in 112 lesions (93.3%). No rats were lost. In the etanercept group, the lesions' volumes were 83.9 ± 13.1, 47.2 ± 8.4, and 96.7 ± 34.8 mm(3) at the end of the second week (pretreatment stage), at the end of the fourth week (post-treatment stage), and at the end of the sixth week, respectively (P = 0.007). Histopathologic scores were 2.3 ± 0.2, 1.7 ± 0.2, and 1.9 ± 0.1, respectively (P = 0.08). The changes in the other groups were not statistically significant. Etanercept, a fusion protein consisting of human recombinant soluble TNF receptor-2, neutralizes TNF activity. Anti-TNF therapy could be a new non-hormonal therapeutic option for the treatment of endometriosis in humans.Archives of Gynecology 06/2011; 283(6):1297-302. · 0.91 Impact Factor -
Article: Efficacy of melatonin and hyaluronate/carboxymethylcellulose membrane in preventing adhesion reformation following adhesiolysis in a rat uterine model.
[show abstract] [hide abstract]
ABSTRACT: To evaluate the efficacy of hyaluronate/carboxymethylcellulose (HA/CMC) membrane and melatonin separately and in combination in reducing adhesion reformation following adhesiolysis of surgically induced adhesions in a rat uterine horn adhesion model. A randomized, prospective study was carried out in a university animal laboratory. Ninety-eight female Sprague-Dawley albino rats were operated on. Following infliction of standard lesions, all the animals underwent second operations after one week. In all the animals, there were dense and vascular adhesions only between the uterine horns. These adhesions were lysed. Following the completion of adhesiolysis, the animals were randomized before closure of the abdomen to one of four groups (melatonin, HA/CMC membrane, combination of melatonin and HA/CMC membrane, control group). Seven days after the second surgery, the third operations were carried out and adhesions were scored. The main outcome measures were type, tenacity, and extent of adhesions. Total adhesion scores were determined. Adhesion scores in the melatonin and HA/CMC membrane groups were similar, and significantly lower than those in the control group (P < 0.001). Adhesion scores in the combination group were lower than those in the other three groups (P < 0.001). Melatonin and HA/CMC membrane are both effective separately in preventing adhesion reformation following adhesiolysis, but in combination they are significantly more beneficial.Journal of Obstetrics and Gynaecology Research 02/2011; 37(2):125-31. · 0.94 Impact Factor -
Article: Responsiveness of urogynecologic quality of life measurements to change after radical gynecologic surgery.
[show abstract] [hide abstract]
ABSTRACT: In order to assess the responsiveness of short forms of the Incontinence Impact Questionnaire (IIQ-7) and Urogenital Distress Inventory (UDI-6) in a subset of women undergoing radical operations for gynecologic cancer. Women with cervical cancer without any abnormal urodynamic abnormalities who had undergone Class III hysterectomy were included in the study. All women underwent urodynamic investigation and completed the IIQ-7 and UDI-6 questionnaires pre-operatively and post-operatively in the sixth month. Twenty-eight patients were enrolled and general and subscale scores of the questionnaire were calculated in the study between February 2008 and September 2008. Class III hysterectomy was performed in 28 women with stage Ib cervical carcinoma. Scores of IIQ-7 and the irritative and obstructive subscales of UDI-6 in the sixth post-operative month were significantly higher than the pre-operative scores. The Cronbach's α was 0.84. Cystometric parameters were in concordance with these changes in the questionnaire scores. The IIQ-7 and UDI-6 questionnaires are sensitive to changes in patients who have undergone radical oncologic operations because their life impact of incontinence may be affected. Validated questionnaires are reasonable measures to detect these changes, which are confirmed by urodynamic findings.Archives of Gynecology 12/2010; 284(5):1259-63. · 0.91 Impact Factor -

Article: The significance of the number of CGG repeats and autoantibodies in premature ovarian failure.
[show abstract] [hide abstract]
ABSTRACT: The objective of this study was to determine whether there was a threshold for the number of CGG repeats in the FMR1 (fragile X) gene in premature ovarian ageing and premature ovarian failure and to investigate the association of this sequence with serum concentrations of anti-Müllerian hormone (AMH), inhibin B, anti-thyroid and anti-adrenal autoantibodies. In this prospective randomized controlled preliminary study, the number of triple CGG repeats and serum concentrations of FSH, AMH and aforementioned autoantibodies were evaluated in 79 women who were younger than 40 years old. FSH concentrations were between 12 and 50 IU/ml (premature ovarian ageing) in 30 women and were higher than 50 IU/ml (premature ovarian failure) in nine women; FSH concentrations were normal in 40 women. All women whose FSH concentrations were higher than 12 IU/ml had CGG repeats greater than 30. No women whose FSH concentrations were normal had a repeat number above 30. There was no significant relationship between the levels of antibodies and either CGG repeat numbers or FSH concentrations. In conclusion, the number of CGG repeats between 30 and 40 might be used to predict premature ovarian ageing and premature ovarian failure in infertile women.Reproductive biomedicine online 02/2010; 20(6):776-82. · 2.04 Impact Factor
