Intermenstrual pelvic pain, quality of life and mood

BACKGROUND/AIMS

To investigate the independent importance of different types of pelvic pain on quality of life and depressive symptoms.

METHODS

A cross-sectional study was performed on patients with pelvic pain. A 10-cm visual-analogue scale (VAS) was used to investigate intensity of intermenstrual pelvic pain, dysmenorrhea or deep dyspareunia. The SF-36 form and the Zung Self-Rating Scale for Depression (SDS) were used to investigate quality of life and depressive symptoms, respectively.

RESULTS

The final study group consisted of 248 patients, 175/248 (70.6%) with intermenstrual pelvic pain, 46/248 (18.5%) with dysmenorrhea and 27/248 (10.9%) with deep dyspareunia associated or not with dysmenorrhea. Mean VAS score for dysmenorrhea was higher than that for deep dyspareunia (p < 0.003) and intermenstrual pelvic pain (p < 0.0001). Women with intermenstrual pelvic pain had the worst SF-36 (p < 0.0001) and SDS (p < 0.002) scores. SF-36 was independently and inversely related to intermenstrual pelvic pain (CR -1.522; 95% CI -2.188 to -0.856; p < 0.0001), and less strongly to dysmenorrhea (CR -0.729; 95% CI -1.487 to 0.030; p = 0.06). Indeed, only the physical component summary of SF-36 was independently related to dysmenorrhea (CR -0.956; 95% CI -1.783 to -0.129; p = 0.024). The SDS score was independently related only to intermenstrual pelvic pain (CR 0.573; 95% CI 0.241-0.904; p = 0.0008).

CONCLUSIONS

Patients with intermenstrual pelvic pain have the worst SF-36 and SDS scores. Intermenstrual pelvic pain seems to be more strongly associated with a reduced quality of life and depressive mood.

Prevalence of menstrual pain in young women: what is dysmenorrhea?

Objectives

This study aimed to determine the frequency of dysmenorrhea, as identified by different definitions, in a population of young women, and to investigate factors associated with this complaint.

Materials and methods

A final group of 408 young women completed a self-assessment questionnaire. This was a cross-sectional analytical study.

Results

Menstrual pain was reported by 84.1% of women, with 43.1% reporting that pain occurred during every period, and 41% reporting that pain occurred during some periods. Women with menstrual pain had an earlier menarche (P = 0.0002) and a longer menstrual flow (P = 0.006), and this group was characterized as having a higher prevalence of smokers (P = 0.031) and a lower prevalence of hormonal contraception users (P = 0.015). Pain intensity was correlated (r = 0.302, P < 0.0001) positively with menstrual flow length (CR = 0.336), history of abortions (CR = 3.640), and gynecological pathologies (CR = 0.948), and negatively with age at menarche (CR = −0.225), use of hormonal contraception (CR = −0.787), and history of gynecological surgery (CR = −2.115). Considering the parameters of menstrual pain, a need for medication, and inability to function normally (absenteeism from study or social activities) alone or together, the prevalence of dysmenorrhea is 84.1% when considering only menstrual pain, 55.2% when considering the association between menstrual pain and need for medication, 31.9% when considering the association between menstrual pain and absenteeism, and 25.3% when considering the association between menstrual pain, need for medication, and absenteeism (P < 0.0001). The probability of having more severe dysmenorrhea is directly related to pain intensity as measured by a visual analog scale, but does not coincide with it.

Conclusion

Menstrual pain is a very common problem, but the need for medication and the inability to function normally occurs less frequently. Nevertheless, at least one in four women experiences distressing menstrual pain characterized by a need for medication and absenteeism from study or social activities.

The ovarian follicular pool and reproductive outcome in women

Both quantitative and qualitative aspects of the ovarian reserve are inversely related to age, hence the relationship existing between low quantity and low quality may be only indirect and depending on their strong relationship with the third variable, namely women's age. However the possibility exists that they may also be directly related. The objective of this study was to investigate the relationship between ovarian reserve and female reproductive outcome. Eight published studies reporting histological data on the human ovaries have been carefully reviewed. Only studies where the reproductive history of women was reported have been included for the analysis. The non-growing follicle count was plotted versus age and the best fit line through the data was calculated. All patients were assigned as to be above or below the calculated median hence differentiating women with high or low ovarian reserve for their age. A similar number of pregnancies ended in miscarriage in women with low and high ovarian reserve. The number of deliveries per woman in both the groups was not statistically different. The results of the study do not support the hypothesis that quality and quantity of the follicular pool are directly related.

The current TNM staging system of renal cell carcinoma: are further improvements needed?

Objective of the study is to review the current 7th edition of the TNM classification of renal tumors and to perform a critical analysis of the recent evidence in order to identify the limitations of this new staging system. A search of the english literature was performed through the Medline and Pubmed database using the following keywords: renal cell carcinoma, staging system and TNM. Overall, 2600 references were initially scrutinized. Forty papers were selected based on their pertinence with the topic of the review, level of evidence provided and overall contribution to the field. Few changes have been made in the current version of the TNM staging system of renal tumors. pT2 tumors have been divided in 2 subgroups based on tumor size with a cut-off at 10 cm; the invasion of the renal vein was classified as pT3a; finally, the invasion of the ispsilateral adrenal gland was classified as pT4. However, other changes were suggested by the analysis of the recent literature and have not been introduced in this new version. Further improvements of the TNM classification for renal tumors are needed especially with regard to locally advanced tumors and node-positive disease, in order to improve the accuracy of this important prognostic tool in renal oncology.

Second trimester amniocentesis is not a risk factor for very low birth weight and extremely low birth weight

Objectives. To assess the risk of very low birth weight (VLBW) and extremely low birth weight (ELBW) attributable to second trimester amniocentesis. Methods. Records of 4,877 consecutive amniocentesis, performed between 1997 and 2003, were analyzed. Only VLBW and ELBW in the study population (exposed) and in the control group (unexposed) were evaluated. Comparisons were made between the amniocentesis group versus nonexposed. Odds ratios (OR) and 95% confidence intervals (95% CI) were calculated for VLBW and ELBW classes. Results. In the study population, the VLBW were 35 (0.71%) and the ELBW were 20 (0.41%). In the control group, the VLBW were 220 (0.67%) and the ELBW were 112 (0.34%). The Odds ratios of the VLBW between the study and the control group did not show any statistical significant risk (OR = 1.07, 95% CI = 0.72–1.54). Also in ELBW odds ratios between study and control group were not statistically significant (OR = 1.20, 95% CI = 0.7–1.95). Conclusions. No effect of the second trimester amniocentesis was noted on VLBW and ELBW.

Surfactant protein D and KL-6 serum levels in systemic sclerosis: correlation with lung and systemic involvement

OBJECTIVE

The aim of this study was to investigate the relationship between SP-D and KL-6 serum concentrations and the extent of interstitial lung involvement, as measured by a quantitative HRCT score and the functional impairment, in patients with systemic sclerosis (SSc). Moreover we analysed the association between these lung-specific biomarkers and skin involvement, anti-Scl-70 antibody titres and an index of disease activity.

METHODS

Serum SP-D, KL-6 and anti-Scl-70 concentrations were determined by ELISA in 25 SSc patients. Disease activity and lung function parameters were assessed, and the extent of ILD was measured by a HRCT score.

RESULTS

SP-D and KL-6 concentrations were higher in patients with SSc and lung fibrosis than in healthy controls. KL-6 correlated positively with the HRCT-fibrosis score (r=0.68, p<0.001), SP-D showed a weaker correlation (r=0.44, p=0.025). Increased KL-6 concentrations were associated with decreased DLCO and decreased FVC in SSc patients, SP-D showed no association. Furthermore KL-6, but not SP-D, showed a strong association with skin involvement as expressed by the modified Rodnan skin score (r=0.71, p<0.0001) and a disease activity index (r=0.73, p<0.0001).

CONCLUSION

KL-6 is more strongly associated than SP-D with the HRCT-fibrosis score, and, different from SP-D, it correlates with skin involvement and disease activity. We suggest that KL-6 may be a useful biomarker in the assessment of scleroderma patients.

The transvaginal probe as a uterine manipulator: a new technique to simplify transabdominal chorionic villus sampling in cases with difficult access to the trophoblast

OBJECTIVES

To evaluate the efficacy of using the transvaginal probe to manipulate the uterus and change the position of the trophoblast, and to simplify access to the chorionic villus under difficult conditions.

METHODS

One thousand five hundred and thirty-nine procedures were performed in our centre in 1524 pregnant women from September 2006 to September 2009. In 90 of these, a difficult access to the trophoblast was observed and uterine manipulation under continuous ultrasound guidance with a double needle technique, was applied to obtain the sample. Of these, 86 samples were taken from singleton pregnancies and 4 from two bichorionic twin pregnancies

RESULTS

One thousand five hundred and thirty-nine transabdominal chorionic villus sampling (TA-CVS) procedures were conducted on 1524 pregnant women. As many as 1449 were performed without manipulation with the transvaginal probe and in 90 cases the manipulation was carried out. In 89 cases, access to the trophoblast was difficult and the uterus was manipulated, which enabled an adequate TA-CVS to be performed with a single aspiration. In one case, TA-CVS was not performed due to significant pelvic pain in a patient with a fixed, retroflexed uterus and a previous history of endometriosis.

CONCLUSIONS

Uterine manipulation with the transvaginal probe may be a useful solution in cases where TA-CVS is limited by difficult access to the trophoblast.

Anti-Müllerian hormone-based prediction model for a live birth in assisted reproduction

Prediction of assisted reproduction treatment outcome has been the focus of clinical research for many years, with a variety of prognostic models describing the probability of an ongoing pregnancy or a live birth. This study assessed whether serum anti-Müllerian hormone (AMH) concentrations may be incorporated into a model to enhance the prediction of a live birth in women undergoing their first IVF cycle, by analysing a database containing clinical and laboratory information on IVF cycles carried out between 2005 and 2008 at the Mother-Infant Department of University Hospital, Modena. Logistic regression was used to examine the association of live birth with baseline patient characteristics. Only AMH and age were demonstrated in regression analysis to predict live birth, so a model solely based on these two criteria was generated. The model permitted the identification of live birth with a sensitivity of 79.2% and a specificity of only 44.2%. In the prediction of a live birth following IVF, a distinction, however moderate, can be made between couples with a good and a poor prognosis. The success of IVF was found to mainly depend on maternal age and serum AMH concentrations, one of the most relevant and valuable markers of ovarian reserve.

Paclitaxel-hyaluronic acid for intravesical therapy of bacillus Calmette-Guérin refractory carcinoma in situ of the bladder: results of a phase I study

PURPOSE

Carcinoma in situ represents high grade anaplasia of the bladder mucosa. Intravesical immunotherapy with bacillus Calmette-Guérin is the gold standard treatment for patients with carcinoma in situ. Patients with carcinoma in situ refractory to bacillus Calmette-Guérin are candidates for major surgery such as radical cystectomy. We identified the maximum tolerated dose and the recommended dose, and evaluated the safety profile of paclitaxel-hyaluronic acid bioconjugate given by intravesical instillation to patients with carcinoma in situ refractory to bacillus Calmette-Guérin.

MATERIALS AND METHODS

A total of 16 patients with carcinoma in situ refractory to bacillus Calmette-Guérin were enrolled in a phase I, open label, single institution study. A minimum of 3 eligible patients were included per dose level. Paclitaxel-hyaluronic acid solution (ONCOFID-P-B™) was administered for 6 consecutive weeks. The primary objective was to identify the maximum tolerated dose and the recommended dose. As secondary objectives the safety profile of ONCOFID-P-B, the pharmacokinetic profile after each instillation and the tumor response were also evaluated.

RESULTS

No dose limiting toxicity occurred at any drug level evaluated. The plasma levels of the study drug were always below the lower limit of quantification at all tested doses after each instillation. A total of 11 adverse events were reported by 7 patients and 9 (60%) showed complete treatment response.

CONCLUSIONS

Intravesical instillation of ONCOFID-P-B for carcinoma in situ refractory to bacillus Calmette-Guérin showed minimal toxicity and no systemic absorption in the first human intravesical clinical trial to our knowledge. Finally, satisfactory response rates were observed.
