The use of the transdermal contraceptive patch is associated with greater bioavailability of ethinyl estradiol (EE) compared with contraceptive vaginal ring or oral contraceptives (OC). We compared the influences of three contraceptive methods (OC, vaginal ring, and transdermal patch) on serum levels of coenzyme Q(10), alpha-tocopherol, gamma-tocopherol and total antioxidant capacity in premenopausal women. Blood samples from 30 premenopausal women who used hormonal contraception for at least 4 months were collected.

Introduction And Hypothesis: We aimed to identify factors contributing to successful pessary use for over 1 year.

Methods: A chart review was conducted composed of 150 women at Montefiore Medical Center, using a pessary for over 1 year. Characteristics of those who continued pessary usage were compared with those who discontinued use by using Chi-square, Fisher's exact test, logistic regression model, receiver-operator characteristic curve, and Kaplan-Meier survival curves.

While investigating whether proteins retrieved by cervicovaginal lavages (CVL) from women with cervical intraepithelial neoplasia (CIN) might correlate with risk of progression to invasive cervical cancer, we unexpectedly identified HIV gag and env glycoprotein in CVL from women with HIV-negative serology. HIV antigens were consistently identified by mass spectrometry (MS) in CVL from 4 women but were absent in CVL from the remaining 16 women. HIV serologies of all 20 patients were negative for both HIV-1 and HIV-2 antibodies.

Introduction And Hypothesis: The objective of this study was to identify nerve(s) vulnerable to entrapment during uterosacral ligament fixation (USLF), which could cause postoperative lower extremity pain previously described in the literature.

Methods: Preserved cadavers in a medical anatomy course were used. Before the students' pelvic dissections, a 2-0 prolene suture was placed in the middle third of each left uterosacral ligament visualized.

Although gross hematuria is a relatively uncommon condition in general obstetrics and gynecology practice, microscopic hematuria is a common incidental finding during routine antepartum or gynecologic office visits. The proper evaluation and treatment options are understudied in females. In fact, work-up of females is controversial, and no consensus guidelines exist at this time.

Our objective was to document variations in the topography of pelvic floor nerves (PFN) and describe a nerve-free zone adjacent to the sacrospinous ligament (SSL). Pelvic floor dissections were performed on 15 female cadavers. The course of the PFN was described in relation to the ischial spine (IS) and the SSL.

We described the innervation of the levator ani muscles (LAM) in human female cadavers. Detailed pelvic dissections of the pubococcygeus (PCM), iliococcygeus (ICM), and puborectalis muscles (PRM) were performed on 17 formaldehyde-fixed cadavers. The pudendal nerve and the sacral nerves entering the pelvis were traced thoroughly, and nerve branches innervating the LAM were documented.

Background: Isolated incisional herniation of the bladder is very rare following pelvic surgery and may present as suprapubic discomfort. We report a case of incisional bladder hernia following pelvic surgery presenting as refractory urinary urgency.

Case: A 70-year-old woman, para 2, presented with a long history of suprapubic tenderness and refractory urinary urgency following reconstructive pelvic surgery.

The present study examines the influence of menopause and hormone replacement therapy (HRT) on serum levels of coenzyme Q(10) and other lipid-soluble antioxidants in normal women. Serum levels of coenzyme Q(10), alpha-tocopherol, gamma-tocopherol, beta-carotene and lycopene in 50 premenopausal women (not using oral contraceptives), 33 healthy postmenopausal and 15 postmenopausal women on HRT ("Prempo"; combination of 0.625 mg conjugated estrogen and 2.

Objective: The purpose of this study was to examine the influence of menstrual cycle and oral contraceptive use on serum levels of lipid-soluble antioxidants.

Study Design: In this cross-section study, nonfasting blood samples were collected twice from 10 healthy premenopausal women during the follicular phase (between days 8 and 11) and the luteal phase (between days 18 and 22) of their same menstrual cycle. In addition, blood samples from 15 premenopausal women who used oral contraceptive for at least 6 months and 40 women who did not use oral contraceptive were collected randomly at any day of the menstrual cycle.

Objective: The purpose of this study was to determine effects of ovariectomy (OVX) and conjugated equine estrogens plus medroxyprogesterone acetate (CEE/MPA), or ethinyl estradiol plus norethindrone acetate (EE/NA) on biomechanics of uterosacral (USL) and round (RL) ligaments in postmenopausal (PMP) monkeys.

Study Design: This was a randomized, triple blind, placebo-controlled study. OVX monkeys received 12 months no treatment (Pbo) (n = 19), CEE/MPA (n = 19), or EE/NA (n = 21).

The objective of this study was to review our experience with pessary use for advanced pelvic organ prolapse. Charts of patients treated for Stage III and IV prolapse were reviewed. Comparisons were made between patients who tried or refused pessary use.

The objective of this study was to determine the association of plasma levels of uric acid, an endogenous antioxidant, in women with cervical intraepithelial neoplasia (CIN), while controlling for the confounding effects of human papillomavirus (HPV) infection, age, smoking, and use of oral contraception. Plasma-reduced and oxidized uric acid levels were determined in 650 women by high-performance liquid chromatography, employing electrochemical technique. The findings demonstrated that 1) plasma-reduced uric acid (PRUA) levels in women with CIN (n = 311) were significantly lower (P < 0.

Aims: We studied preoperative and postoperative pressure transmission ratio (PTR) and urethral pressure profilometry in patients undergoing the vaginal wall patch sling technique as a first surgical approach for genuine stress incontinence (GSI) with urethral hypermobility. The specific aims were to determine the exact urodynamic parameters, if any, that may be improved postoperatively and to report the urodynamic outcome of the vaginal wall patch sling technique in successful cases.

Methods: Preoperatively, all patients had a positive standing stress test, urethral hypermobility on Q-tip testing, and normal postvoid residual volume.

Graft augmentation for repair of recurrent pelvic organ prolapse is commonly used in reconstructive pelvic surgery. The reported complications are mainly late onset. We report a case of early-onset inflammatory reaction following bovine pericardium graft augmentation for posterior vaginal wall defect repair.

This study aimed to determine whether preoperative pessary reduction of anterior vaginal wall prolapse in patients with elevated postvoid residual (PVR) volumes relieves urinary retention, and if reconstructive pelvic surgery in these patients cures urinary retention. The records of all women with symptomatic anterior vaginal wall and urinary retention (PVR >or=100 cc) who underwent evaluation and surgical repair of the anterior vaginal wall at our institution between 1996 and 1999 were retrospectively reviewed. All patients underwent a detailed urogynecologic and urodynamic evaluation and had a pessary trial prior to surgery.

Objective: alpha-Tocopherol is a potent antioxidant that protects cell membranes against oxidative damage. Red blood cell alpha-tocopherol levels reflect membrane alpha-tocopherol concentrations, and altered levels may suggest membrane damage. The objective of this study was to determine the levels of alpha-tocopherol and alpha-tocopheryl quinone, the oxidized product of alpha-tocopherol, in plasma and red blood cells that were obtained from control subjects and patients with cervical intraepithelial neoplasia and cervical cancer.

We describe our long-term outcome for patients with genuine stress incontinence (GSI) and urethral hypermobility using a modified vaginal wall patch sling technique. Fifty-three patients were studied. Preoperatively, all patients had a positive standing stress test and urethral hypermobility on Q-tip testing.

It has been hypothesized that in preeclampsia, the antioxidant-deficient state may facilitate increased attacks of free radicals, which may result in endothelial cell damage. The purpose of this study was to investigate the association of three lipid-soluble antioxidants, coenzyme Q10, alpha-tocopherol and gamma-tocopherol, with preeclampsia and normal pregnancy. Serum levels of all three antioxidants in 42 women with normal pregnancies, 25 with mild preeclampsia and 28 with severe preeclampsia were measured by high-pressure liquid chromatography.
