Changes in cell proliferation, but not in vascularisation are characteristic for human endometrium in different reproductive failures--a pilot study

Reproductive failure, determined as recurrent spontaneous abortions (RSA) or recurrent implantation failure (RIF) in women is not well understood. Several factors, including embryo quality, and cellular and molecular changes in endometrium may contribute to the insufficient feto-maternal interaction resulting in reproductive failure. Prior clinical studies suggest an inadequate endometrial growth and development of the endometrium, leading to a lesser endometrial thickness.

Comparison of the effect of a CIDR-Select synch versus a long-term CIDR based AI protocol on reproductive performance in multiparous dairy cows in Swiss dairy farms

Background Synchronization programs have become standard in the dairy industry in many countries. In Switzerland, these programs are not routinely used for groups of cows, but predominantly as a therapy for individual problem cows. The objective of this study was to compare the effect of a CIDR-Select Synch and a 12-d CIDR protocol on the pregnancy rate in healthy, multiparous dairy cows in Swiss dairy farms. Methods Cows (N = 508) were randomly assigned to CIDR-Select Synch (N = 262) or 12-d CIDR (N = 246) protocols. Cows in the CIDR-Select Synch group received a CIDR and 2.5 ml of buserelin i.m. on d 0. On d 7, the CIDR insert was removed and 5 ml of dinoprost was administered i.m.. Cows in the 12-d CIDR group received the CIDR on d 0 and it was removed on d 12 (the routine CIDR protocol in Swiss dairies). On d 0 a milk sample for progesterone analysis was taken. Cows were inseminated upon observed estrus. Pregnancy was determined at or more than 35 days after artificial insemination. As a first step, the two groups were compared as to indication for treatment, breed, stud book, stall, pasture, and farmer's business using chi square tests or Fisher's exact test. Furthermore, groups were compared as to age, DIM, number of AI's, number of cows per farm, and yearly milk yield per cow using nonparametric ANOVA. A multiple logistic model was used to relate the success of the protocols to all of the available factors; in particular treatment (CIDR-Select Synch/12-d CIDR), milk progesterone value, age, DIM, previous treatment of the uterus, previous gynecological treatment, and number of preceding inseminations. Results The pregnancy rate was higher in cows following the CIDR-Select Synch compared to the 12-d CIDR protocol (50.4% vs. 22.4%; P < 0.0001). Conclusion The CIDR-Select Synch protocol may be highly recommended for multiparous dairy cows. The reduced time span of the progesterone insert decreased the number of days open, improved the pregnancy rate compared to the 12-d CIDR protocol and the cows did not to have to be handled more often.

Suspicious axillary lymph nodes in patients with unremarkable imaging of the breast

The aim of this study was to evaluate the pathological findings and the method of tissue harvesting in those patients who have both suspicious axillary lymph nodes and normal imaging of the breast.

Off-label use of misoprostol for labor induction: a nation-wide survey in Switzerland

Off-label use of drugs is frequent in obstetrical practice. No data however are available about nation-wide off-label use in obstetrics regarding frequency and patient information. The objective of our study was to assess the clinical practice of off-label use of misoprostol for labor induction.

Effects of a single administration of prostaglandin F2alpha, or a combination of prostaglandin F2alpha and prostaglandin E2, or placebo on fertility variables in dairy cows 3-5 weeks post partum, a randomized, double-blind clinical trial

BACKGROUND: Delayed uterine involution has negative effects on the fertility of cows; use of prostaglandin F2alpha alone as a single treatment has not been shown to consistently improve fertility. Combined administration of PGF2alpha and PGE2 increased uterine pressure in healthy cows. We hypothesized, that the combination of both prostaglandins would accelerate uterine involution and have, therefore, a positive effect on fertility variables. In commercial dairy farming, the benefit of a single post partum combined prostaglandin treatment should be demonstrated. METHODS: 383 cows from commercial dairy farms were included in this study. Uterine size and secretion were evaluated at treatment 21-35 days post partum and 14 days later. Cows were randomly allocated to one of three treatment groups: PGF2alpha and PGE2, PGF2alpha or placebo. For every animal participating in the study, the following reproduction variables were recorded: Interval from calving to first insemination, days open, number of artificial inseminations (AI) to conception; subsequent treatment of uterus, subsequent treatment of ovaries. Plasma progesterone level at time of treatment was used as a covariable. For continuous measurements, analysis of variance was performed. Fisher's exact test for categorical non-ordered data and exact Kruskal-Wallis test for ordered data were used; pairwise group comparisons with Bonferroni adjustment of significance level were performed. RESULTS: There was no significant difference among treatment groups in uterine size. Furthermore, there was no significant difference among treatments concerning days open, number of AI, and subsequent treatment of uterus and ovaries. Days from calving to first insemination tended to be shorter for cows with low progesterone level given PGF2alpha and PGE2 in combination than for the placebo-group (P = 0.024). CONCLUSION: The results of this study indicate that the administration of PGF2alpha or a combination of PGF2alpha and PGE2 21 to 35 days post partum had no beneficial effect upon measured fertility variables. The exception was a tendency for a shorter interval from calving to first insemination after administration of the combination of PGF2alpha and PGE2, as compared to the placebo group. Further research should be done in herds with reduced fertility and/or an increased incidence of postpartum vaginal discharge.

Do transsexuals have micturition disorders?

OBJECTIVE: Transsexualism occurs with an estimated prevalence of 2.4:100,000 male-to-female (MTF) and 1:100,000 female-to-male (FTM) transsexuals. As sex reassignment surgery involves surgery of the urethra and transsexuals are substituted life-long with the cross gender hormones there could possibly arise micturition disorders. Aim of the study was to determine if transsexuals have an increased risk of micturition disorders and if so which. STUDY DESIGN: Between January and July 2003 we examined 25 transsexuals whereof 18 were MTF and 7 were FTM transsexuals using King's Health Questionnaire, visual analogue scale for patient's well being, perineal and transabdominal ultrasound, urine dipstick and uroflow measurement. RESULTS: 17 out of 25 patients considered themselves very happy. In MTF transsexuals, a diverted stream, overactive bladder and stress urinary incontinence was a common problem. Prostate volume was small with 20 g and palpation did not confirm and solid or suspicious lesions. None of the patients had significant residual urine but MTF transsexuals had a reduced urinary flow. We could not detect a current urinary tract infections in any of the patients. CONCLUSION: Transsexuals have an increased risk for the development of micturition disorders including stress urinary incontinence and overactive bladder compared to age-matched control groups and should be counselled preoperatively. Reasons for the development of incontinence might be surgery including pudendal nerve damage, hormonal reasons and ageing.

Tubal sterilization: Complications of laparoscopy and minilaparotomy

OBJECTIVE: To evaluate whether intra- and post-operative morbidity varies according to the method used for female sterilization. STUDY DESIGN: The database of the Swiss obstetric study group was analyzed for a period of 9 years. After the exclusion of cases with extraneous factors that may have influenced the operative outcome, three groups of patients were identified: (1) interval laparoscopic sterilization unrelated to pregnancy (n=20,325); (2) postpartum laparoscopic sterilization (n=2233); (3) postpartum sterilization by minilaparotomy (n=5095). Intra-operative and post-operative complications were compared according to the surgical approach. RESULTS: A total of 27,653 patients were included in the study. The proportion of major complications was higher in group 3 than in group 1 (0.39% versus 0.10%, odds ratio 4.0, 95% CI 2.15-7.44, p<0.001) but not statistically different between groups 1 (0.10%) and 2 (0.18%). Minor complications were statistically significantly more frequent in group 3 (0.82%) than in group 1 (0.26%) or group 2 (0.27%). There was no case of intra-operative or post-operative death in the study population. CONCLUSION: When available, a laparoscopic approach should be chosen for female sterilization. After uneventful pregnancy course and delivery, it does not seem justified to delay the endoscopic sterilization to a later time.

Gynaecological operations: do they improve sexual life?

Aim of the study was to determine if gynaecological operations have an effect on sexual function using the current medlined literature. We performed a Medline search using the terms "sexual life/function after operative gynaecological treatment", "sexual life/function after operations for gynaecological problems", "sexual life/function after hysterectomy", "sexual life/function, incontinence" and "sexual life/function, pelvic organ prolapse". Reviews were excluded. We divided the operations into four groups of (1) combined prolapse and incontinence operations, (2) prolapse operations only, (3) incontinence operations only and (4) hysterectomy and compared pre-to postoperative sexual outcome. Thirty-six articles including 4534 patients were identified. Only 13 studies used a validated questionnaire. The other authors used self-designed and non-validated questionnaires or orally posed questions by the examiner to determine sexual function. Prolapse operations particularly posterior repair using levator plication seem to deteriorate sexual function, incontinence procedure have some worsening effect on sexual function and hysterectomy seems to improve sexual function with no differences between subtotal or total hysterectomy. Gynaecological operations do influence sexual function. However, little validated data are available to come to this conclusion.

Do women with urinary incontinence really know where all the toilets are? The toilet paper

AIMS OF STUDY: Aim of this study was to determine if women with overactive bladder really do have a more detailed knowledge about toilets and their conditions in their vicinity in comparison to women with urinary stress incontinence and those without any urinary symptoms. PATIENTS AND METHODS: A questionnaire survey of 270 women from three symptom groups, those with stress incontinence, overactive bladder and controls without any bladder symptoms from an inner city area and two local towns. The knowledge of the three groups was compared and measured by a score assessed by the authors who had visited the toilets themselves. RESULTS: Women with overactive bladder are more likely to exhibit precautionary voiding prior to leaving home and have significantly more detailed knowledge about toilets in their neighbourhood. DISCUSSION: The overactive bladder seems to have a greater influence on behaviour and on quality of life than stress incontinence which could mean that they are more tortured by their symptoms.

The feasibility, efficacy and functional outcome of local anaesthetic repair of anterior and posterior vaginal wall prolapse

INTRODUCTION: Urogenital prolapse is a very common condition in women with a prevalence of 30%. If conservative therapy fails or is not desired by the patient, prolapse repair is usually performed under general or regional anaesthetic. The aim of the study was to evaluate feasibility, efficacy and functional outcome after fascial prolapse repairs under local anaesthetic (LA). PATIENTS AND METHODS: Between November 1999 and December 2000, 130 consecutive patients presenting with anterior or posterior prolapse or both were invited to have their procedure performed under LA. All patients with a symptomatic minimum stage II prolapse were included. Prior to surgery all women completed a standardized questionnaire examining the specific and non-specific symptoms of prolapse and their situation was classified using the ICS Pelvic Organ Prolapse (POP-Q) system. Follow up was 30 months. Objective success was defined as a stage 1 or less and no symptoms of bulge, subjective success was defined as lack of specific or non-specific symptoms of prolapse. RESULTS: There were 128 patients who agreed to have their operations performed under LA: 68 in the anterior group, 52 in the posterior group and 8 with a combined anterior and posterior repair. Objective cure rate was 88% for posterior repair, 87% for anterior repair and 63% for combined repair. Success rates were no different in primary from recurrent cases. There were no intraoperative complications and operating time was 21 min (anterior repair) or 23 min (posterior repair). There was no de novo postoperative urinary or stool incontinence and all patients but two would have the operation performed again under the same circumstances. The two remaining refused due to embarrassment but for no other reason. CONCLUSION: Local anaesthetic prolapse repair is feasible and effective in middle term results. It is well accepted by the patients who benefit from less side effects and short hospital stay.

Acute stress reactions in the first 3 weeks postpartum: A study of 219 parturients

OBJECTIVES: There is increasing research on posttraumatic stress (PS) 4-6 weeks and 3 months postpartum, but, there are no data on acute stress reactions (ASR) in the first 3 weeks postpartum, i.e. the potential precursors of PS. However, ASR may have long-term effects, e.g., on a subsequent pregnancy without having manifested as PS in the meantime. We propose: (i) to describe the patterns of ASR after childbirth, (ii) to explore differences between women with normal and traumatogenic ASR, and (iii) to provide data on the early detection of traumatogenic ASR 2 and 3 weeks postpartum. STUDY DESIGN: Intra-event variables (relationship with caregivers, overall birth experience, and dissociative experiences, as well as obstetric variables) were assessed 48-96h. postpartum, as were ASR (by means of the Impact-of-Event Scale IES) in weeks 1, 2, and 3 postpartum. According to research on PS the upper 33%-range of ASR in weeks 2 and 3 was defined as 'traumatogenic'. RESULTS: Normal ASR in week 1 are at a level which in non-obstetric trauma-situations is considered as the upper range of low stress or lower range of medium distress. ASR decline constantly from week 1 to week 3. However, high ASR in week 1 do not drop faster than do low ones, thus indicating a prolonged stress reaction in women with high ASR in week 1. Low ASR (IES-scores <10) and high ASR (IES-scores >20) in week 1 are highly predictive for normal ASR, and traumatogenic ASR in weeks 2 and 3, respectively. Medium ASR (IES-scores 10-20) in week 1 are of uncertain predictive value for stress reactions in weeks 2 and 3 and have to be re-assessed at that time. CONCLUSIONS: Clinical screening for ASR appears to be helpful in detecting women with a compromised ability to process childbirth-related stress. The association between ASR and long-term development should be further explored.

The correlation of urethral resistance pressure with maximum urethral closure pressure and stress incontinence

OBJECTIVE: Aim of the study was to correlate urethral retro resistance pressure with the maximum urethral closure pressure (MUCP) and functional urethral length (FUL) in patients with urinary incontinence and healthy individuals. STUDY DESIGN: Two hundred and twenty patients with the complaint of urinary incontinence had a urodynamic examination including urethral pressure profiles and URP. Additionally, 15 healthy individuals without the complaint of any incontinence had their URP and urethral pressure profiles measured. The correlation of MUCP, FUL and URP were calculated using Graph Pad Instat 4.0 for windows. RESULTS: URP correlates well with the diagnosis of urodynamic stress incontinence. Correlation coefficient between URP and MUCP is 0.9262. Healthy individuals have significantly higher values for URP and MUCP. CONCLUSION: URP is a valuable less invasive test than conventional urethral function tests for the diagnosis of urodynamic incontinence with an excellent correlation of MUCP and URP.

The Young's modulus of fetal preterm and term amniotic membranes

OBJECTIVE: To examine the Young's modulus of the human amniotic membranes, as well as its relationship to gestational age. To determine whether cellular and material-related parameters affect this modulus. STUDY DESIGN: In a prospective study at the Obstetric outpatient clinic of the University Hospital Zurich Young's modulus, thickness and mesenchymal:epithelial cell ratio of amniotic membranes of preterm (N=23) and term (N=40) placentae were examined. Significance (P<0.05) was calculated with the Mann-Whitney two-sample rank sum test and Wilcoxon signed rank test, while correlations were made using the Spearman's correlation. RESULTS: The Young's modulus of preterm amniotic membranes was significantly higher than that of term membranes. It varied within the same amniotic membrane. The thickness of the amnion in both preterm and term membranes did not differ significantly. The thinner the preterm and term amniotic membranes, the higher the Young's modulus was. There was no relation to the mesenchymal:epithelial cell ratio in the amnion. CONCLUSIONS: Preterm amniotic membranes are stiffer than term amniotic membranes. Tentatively, we hypothesise that there may be a correlation between the extracellular matrix components and the elastic properties of the membrane.
