Our objective was to evaluate the efficacy of cul-de-sac obliteration in preventing pelvic floor anatomical defects formation
following Burch colposuspension. We evaluated 441 patients who had undergone Burch colposuspension. The patients were divided
into two groups: group A (132 patients) who underwent Burch colposuspension only, and group B (309 patients) who had had a
concomitant cul-de-sac obliteration. Cul-de-sac obliteration was performed using two different techniques, the Moschocowitz
procedure in 131 patients, and approximation of the sacrouterine ligaments in 178 patients. The follow-up period was 8.6 years
(range 3–16). In total we found 43/441 (9.7%) postoperative anatomical defects. Obliteration of the cul de sac significantly
(P<0.0001) reduced the formation of anatomical defects compared to Burch colposuspension. In a comparison of the two surgical
procedures for cul-de-sac obliteration, the approximation of the sacrouterine ligaments was significantly more effective than
either the Moschcowitz procedure (P<0.001) or the Burch colposuspension alone (P<0.001). The Moschcowitz procedure reduced the formation of anatomical defects to 15/131 (11.4%) compared to Burch colposuspension
only (25/132; 18.9%), but statistically the difference was insignificant. The time of anatomical defect detection was significantly
reduced after cul-de-sac obliteration: 2 years 6/25 (24%) in group A compared to 1/8 (5.5%) in group B (P<0.01). After 5 years the detection rate was 64% (16/25) and 22.2% (4/18) respectively (P<0.01). It was concluded that cul-de-sac obliteration using approximation of the sacrouterine ligaments significantly reduced
the incidence of anatomical defect formation following Burch colposuspension. A long follow-up period is needed to evaluate
the truce incidence.

Bombesin was originally isolated from amphibian skin, wherease its mammalian counterpart, gastrin-releasing peptide (GRP), was first identified in the nervous system of the gastrointestinal tract. Whether GRP is present in the human skin is not known. Bombesin-like peptides are also known to modulate growth. We therefore investigated whether human melanoma cell lines express functional GRP-preferring bombesin receptors and whether they alter growth or other specific cellular functions of these tumour cells. GRP receptor mRNA was found in HBL, D-10, Me-28 and A375-6 cell lines, but only A375-6 cells express a large number of high-affinity binding sites for [125 I]-[Tyr4 ] bombesin ( K d 0.31 ± 0.04 nmol L−1 , 3880 ± 429 binding sites per cell). Bombesin dose-dependently increased cytosolic calcium, but did not alter interleukin (IL) 1β-induced reduction of cell viability or IL-6 secretion, both A375-6-specific cell functions. Growth of A375-6 cells was not altered by bombesin or the specific GRP receptor antagonist BIM26226 as measured by [3 H]-thymidine incorporation or methylene blue assay, whereas insulin alone or in combination with other potential growth factors dose-dependently stimulated growth of these cells. The newly characterized GRP-preferring bombesin receptors on highly malignant human melanoma cells could initiate studies of growth effects on solid tumours or in vivo scanning using radiolabelled tracers. 相似文献

Study ObjectivesTo investigate the phenomenon of recurrent adnexal torsion during the same pregnancy, describe its risk factors, and suggest possible management of this entity.DesignRetrospective case-control study (Canadian Task Force classification II-3).SettingGynecologic endoscopy unit in a university hospital.Patients and interventionsPregnant women with surgically proved adnexal torsion were retrospectively identified from 1993 to 2007. Details of clinical presentation, method of conception, preoperative ultrasound findings, and operative findings were analyzed.InterventionComparison of characteristics of patients with recurrent episodes of adnexal torsion during the same pregnancy vs a single episode of torsion.Measurements and Main ResultsThirty-three pregnant women with 38 episodes of adnexal torsion were included in the study. Seventeen pregnancies (51.5%) were spontaneously conceived. Twenty-eight women had a single episode of torsion, and 5 women (15.1%) had recurrent episodes of torsion during the same pregnancy. No significant differences were found between the 2 groups in age, method of conception, and gestational age at time of torsion. However, ultrasound studies demonstrated that multicystic ovaries were significantly more common in women with recurrent torsion compared with women with a single episode of torsion (80% vs 25%; p = .02). The interval between the first and second episodes of torsion ranged from 1 to 4 weeks.ConclusionPregnant women are at risk for recurrent torsion, especially when the ovaries are enlarged and ultrasound studies demonstrate multiple cysts. Cyst aspiration may prevent recurrent torsion during the same pregnancy. 相似文献

The clinical and urodynamic short term results after colposuspension for urinary stress incontinence has been studied in a group of young patients in whom menopause was induced surgically and compared with a similarly treated group who did not undergo surgical castration. Clinically, no differences were found in the incidence of diurnal frequency, nocturia, urgency, urge incontinence or stress incontinence between the groups. No urodynamic changes in the cystometric, uroflowmetry and urethral pressure profile measurements were found post-operatively between the two groups. It is concluded that surgically induced menopause in the absence of aging has no effect on the results of colposuspension for urinary stress incontinence in the short term. 相似文献

Fifty-nine women with early unruptured tubal pregnancy were treated by a single local injection of methotrexate at laparoscopy. All 59 patients underwent the procedure without any adverse reaction, 47 (80%) of them needing no laparotomy. Twelve patients required a laparotomy for reasons such as rising beta-hCG levels and abdominal pain with or without rising levels of beta-hCG. Only one patient ruptured the tube. None of the women needed a blood transfusion. We found tubal patency in 19 out of 21 patients at follow up hysterosalpingography. Eleven pregnancies were subsequently reported, one of them tubal. The appearance of the injected tube was absolutely normal in three patients, one at cesarean section and two at repeated laparoscopy. No peritubal adhesions were observed. We suggest that this new technique is a safe and effective alternative to laparotomy in a patient with an early unruptured tubal pregnancy. 相似文献

Sixty-nine premenopausal and 53 postmenopausal women had a colposuspension operation for urinary stress incontinence. A significant postoperative reduction (p less than 0.001) of symptoms of frequency, nocturia, urgency and urge incontinence was obtained in both groups. Postoperatively, 88.4 per cent of the premenopausal women were found to be dry compared with 66 per cent in the postmenopausal group (p less than 0.01). No differences were found preoperatively and postoperatively in the cystometric values or in the urethral pressure profiles at rest in both groups and between the groups. The pressure transmission ratios were significantly improved postoperatively in both groups. The postoperative transmission ratios in the premenopausal women were found to be significantly higher than those in the postmenopausal group, at the middle two-quarters of the urethra. Although surgical treatment for urinary stress incontinence in postmenopausal women results in lower cure rates than in younger women, it should be considered. 相似文献

Defective Jak-STAT signal transduction pathway in melanoma cells resistant to growth inhibition by interferon-alpha 总被引:3,自引:0,他引:3

Advanced malignant melanoma is an aggressive malignancy with poor prognosis. Current therapeutic strategies have a modest success rate. The most promising treatment consists of a combination of chemotherapy with interferon-alpha, but complete response rates remain less than 15%. Interferon-alpha is also effective in adjuvant therapy for non-advanced melanoma treated surgically. The molecular mechanisms leading to loss of growth restraints and gain of growth-promoting functions during carcinogenesis of malignant melanoma are not understood in detail. Here, we studied 9 human melanoma cell lines with regard to growth inhibition by interferon-alpha and defects in intracellular signal transduction through the Jak-STAT pathway. In 3 cell lines, we found a complete loss of growth restraint by interferon-alpha. In all of them, different components of the Jak-STAT pathway were defective. Since signal transduction through the Jak-STAT pathway is necessary for antiviral and antiproliferative effects of interferons, we conclude that defects in this pathway may be one of the mechanisms that lead to cancer progression through loss of growth-restraining functions. Moreover, our results indicate that a subgroup of melanomas could be completely resistant to interferon-alpha and should therefore not be treated with this cytokine. 相似文献
