Transischioanal trans-sacrospinous ligament rectocele repair with polypropylene mesh: a prospective study with assessment of rectoanal function

Introduction and hypothesis

Despite good anatomical outcomes of pelvic organ prolapse (POP) repair by the vaginal route using synthetic mesh, complications limit their use. Clinical data are needed to generalize prolapse mesh repair by the vaginal route. The current study aims to evaluate midterm rectoanal function and clinical outcomes after transischioanal rectocele repair using a medium weight polypropylene mesh.

Methods

Between March 2003 and June 2004, 230 patients with stage II–IV anterior and/or posterior POP were included in a prospective multicenter study. The current study is based on the analysis of the 116 patients who underwent a rectocele repair via the infracoccygeal route through the sacrospinous ligament. Anatomical cure was defined when rectocele was at stage <II in the Pelvic Organ Prolapse Quantification (POP-Q) system. Postoperative functional results were evaluated using the self-administered Pelvic Floor Distress Inventory (PFDI) and the Pelvic Floor Impact Questionnaire (PFIQ).

Results

Of the 116 patients who received a posterior mesh with two arms via the infracoccygeal route through the sacrospinous ligament, midterm anatomical results were available for 78 women representing 67 % (78/116) of the operated patients. The mean follow-up was 36 (± 8.1) months. No rectal injury occurred during surgery. The objective success rate was 94.8 % and subjective (by patient satisfaction) was 93.23 %. Colorectal-Anal Impact (CRAI) and Colorectal-Anal Distress Inventory (CRADI) scores were both significantly decreased at midterm follow-up in comparison with baseline (42.7 at baseline vs 11.4 at 24- or 36-month follow-up, p?=?0.001 for CRAI, and 81.1 vs 34.4, p?<?0.001 for CRADI) highlighting the benefits of rectocele repair on colorectal-anal function.

Conclusions

Polypropylene mesh with two arms via the infracoccygeal route through the sacrospinous ligament has good anatomical results at midterm follow-up with significant improvement in symptoms and quality of life and is associated with few complications. Obstructive symptoms reported in cases of rectocele can be improved by transvaginal mesh repair.     

Time perception in children treated for a cerebellar medulloblastoma

The aim of the present study was to investigate temporal abilities in children treated by surgery for a malignant tumor in the cerebellum. Children with a diagnosed medulloblastoma and age-paired control children were given a temporal discrimination task (bisection task) and a temporal reproduction task with two duration ranges, one shorter than 1 s and the other longer than 4 s. The motor and cognitive capacities of these children were also assessed by a battery of age-adapted neuropsychological tests. The results did not show any significant difference in performance between the children with or without cerebellar lesions in the temporal discrimination task. It was only in the temporal reproduction task that the children with cerebellar lesions reproduced longer and more variable durations than the other children, but only for the short stimulus durations (≤1 s). In addition, a hierarchical regression analysis revealed that the best predictor of variance in temporal performance was a significantly lower processing speed in children with cerebellar lesions in comparison to their controls. These results indicated that the major cause of deficits in temporal judgments in children with cerebellar lesions was due to their inability to reproduce accurately short temporal intervals in association with low processing speed, rather than to a specific deficit in the perception of time.     

Mycophenolate mofetil in steroid-dependent idiopathic nephrotic syndrome

Background

Prospective studies have established the mycophenolate mofetil (MMF) efficiency in childhood idiopathic nephrotic syndrome (INS) but reports on the long-term outcome are lacking. Moreover, the search for factors influencing its efficiency would be useful to define its place among the other treatments.

Methods

We performed a monocentric retrospective study including 96 children with steroid-dependent INS followed for 4.7 years (median) (IQ 3–6) after the onset of MMF treatment. The characteristics of responder patients (n?=?74), as defined by a 50 % decrease of relapse rate and/or a 60 % decrease of steroid dose, and of non-responder patients (n?=?22) were compared by univariate analysis and multivariate logistic regression.

Results

Withdrawal of prednisone was achieved in 48/96 patients after a median duration of 18.1 months (IQ 7.8–30.0) of MMF. Only 26/48 patients did not relapse under MMF alone. After MMF was stopped in these patients, only six remained in remission without any treatment at last follow-up. Responders had a shorter time to remission at the first flare (9.5 vs. 15 days, p?=?0.02), a shorter disease duration prior to the onset of MMF (22.2 vs. 94.5 months, p?=?0.001), and were younger at the MMF initiation (6.7 vs. 10.1 years, p?=?0.02) than non-responder patients. The age of MMF initiation was an independent factor associated with efficiency (OR?=?0.80, 95 % CI [0.69, 0.93], p?<?0.01).

Conclusions

MMF is more efficient in young patients treated early in the disease course. Nevertheless, MMF has no remnant effect while nearly all patients relapsed after withdrawal of the drug.

     

Is prenatal urethral descent a risk factor for urinary incontinence during pregnancy and the postpartum period?

Introduction and hypothesis

Obstetric trauma during childbirth is considered a major risk factor for postpartum urinary incontinence (UI), particularly stress urinary incontinence. Our aim was to investigate the relation between postpartum UI, mode of delivery, and urethral descent, and to define a group of women who are particularly at risk of postnatal UI.

Methods

A total of 186 women were included their first pregnancy. Validated questionnaires about urinary symptoms during pregnancy, 2 and 12 months after delivery, were administered. Urethral descent was assessed clinically and by ultrasound at inclusion. Multivariate logistic regression analysis was used to determine the risk factors for UI during pregnancy, at 2 months and 1 year after first delivery.

Results

The prevalence of UI was 38.6, 46.5, 35.6, and 34.4 % at inclusion, late pregnancy, 2 months postpartum, and 1 year postpartum respectively. No significant association was found between UI at late pregnancy and urethral descent assessed clinically or by ultrasound. The only risk factor for UI at 2 months postpartum was UI at inclusion (OR 6.27 [95 % CI 2.70–14.6]). The risk factors for UI at 1 year postpartum were UI at inclusion (6.14 [2.22–16.9]), body mass index (BMI), and urethral descent at inclusion, assessed clinically (7.21 [2.20–23.7]) or by ultrasound. The mode of delivery was not associated with urethral descent.

Conclusions

Prenatal urethral descent and UI during pregnancy are risk factors for UI at 1 year postpartum. These results indicate that postnatal UI is more strongly influenced by susceptibility factors existing before first delivery than by the mode of delivery.
