RESUMEN

BACKGROUND: Bowel symptoms are commonly experienced by patients with Multiple sclerosis (PwMS), but no specific questionnaire validated in this population allows a rigorous assessment. OBJECTIVE: Validation of a multidimensional questionnaire assessing bowel disorders in PwMS. METHODS: A prospective, multicenter study was conducted between April 2020 and April 2021. The STAR-Q (Symptoms' assessmenT of AnoRectal dysfunction Questionnaire), was built in 3 steps. First, literature review and qualitative interviews were performed to create the first version, discussed with a panel of experts. Then, a pilot study assessed comprehension, acceptation and pertinence of items. Finally, the validation study was designed to measure content validity, internal consistency reliability (alpha coefficient of Cronbach) and test-retest reliability [intraclass correlation coefficient (ICC)]. The primary outcome was good psychometric properties with Cronbach's α>0.7 and ICC>0.7. RESULTS: We included 231 PwMS. Comprehension, acceptation and pertinence were good. STAR-Q showed a very good internal consistency reliability (Cronbach's α=0.84) and test-retest reliability (ICC=0.89). Final version of STAR-Q was composed of 3 domains corresponding in symptoms (Q1-Q14), treatment and constraints (Q15-Q18) and impact on quality of life (Q19). Three categories of severity were determined (STAR-Q≤16: minor, between 17 and 20: moderate, and≥21: severe). CONCLUSIONS: STAR-Q presents very good psychometric properties and allows a multidimensional assessment of bowel disorders in PwMS.

RESUMEN

INTRODUCTION: Improved life expectancy and prenatal screening have changed the demographics of spina bifida (spinal dysraphism) which has presently become a disease of adulthood. Urinary disorders affect almost all patients with spinal dysraphism and are still the leading cause of mortality in these patients. The aim of this work was to establish recommendations for urological management that take into account the specificities of the spina bifida population. MATERIALS AND METHODS: National Diagnosis and Management Guidelines (PNDS) were drafted within the framework of the French Rare Diseases Plan at the initiative of the Centre de Référence Maladies Rares Spina Bifida - Dysraphismes of Rennes University Hospital. It is a collaborative work involving experts from different specialties, mainly urologists and rehabilitation physicians. We conducted a systematic search of the literature in French and English in the various fields covered by these recommendations in the MEDLINE database. In accordance with the methodology recommended by the authorities (Guide_methodologique_pnds.pdf, 2006), proposed recommendations were drafted on the basis of this literature review and then submitted to a review group until a consensus was reached. RESULTS: Bladder dysfunctions induced by spinal dysraphism are multiple and varied and evolve over time. Management must be individually adapted and take into account all the patient's problems, and is therefore necessarily multi-disciplinary. Self-catheterisation is the appropriate micturition method for more than half of the patients and must sometimes be combined with treatments aimed at suppressing any neurogenic detrusor overactivity (NDO) or compliance alteration (anticholinergics, intra-detrusor botulinum toxin). Resort to surgery is sometimes necessary either after failure of non-invasive treatments (e.g. bladder augmentation in case of NDO resistant to pharmacological treatment), or as a first line treatment in the absence of other non-invasive alternatives (e.g. aponeurotic suburethral tape or artificial urinary sphincter for sphincter insufficiency; urinary diversion by ileal conduit if self-catheterisation is impossible). CONCLUSION: Spinal dysraphism is a complex pathology with multiple neurological, orthopedic, gastrointestinal and urological involvement. The management of bladder and bowel dysfunctions must continue throughout the life of these patients and must be integrated into a multidisciplinary context.

RESUMEN

INTRODUCTION: Several patterns of urological dysfunctions have been described following spinal cord injury (SCI), depending on the level and the completeness of the injury. A better understanding of the natural history of neurogenic bladder in patients with SCI, and the description of their successive therapeutic lines based on their clinical and urodynamic pattern is needed to improve their management. This study aimed to describe the real-life successive therapeutic lines in patients with neurogenic lower urinary tract dysfunction (NLUTD) following SCI. METHODS: We conducted a two-center retrospective review of medical files of patients with SCI followed in two French specialized departments of Physical Medicine and Rehabilitation between January 2000 and January 2018. All patients with SCI with a level of lesion bellow T3 and older than 18 years old were eligible. The primary outcome was the description of the natural journey of neurogenic bladder in this population, from the awakening bladder contraction to the last therapeutic line. Survival curves were calculated with a 95-confidence interval using the Kaplan-Meier method. RESULTS: One hundred and five patients were included in this study. Most of the patients were young men with a complete SCI lesion. The median time of treatment introduction was 1 and 9 years for anticholinergics and intradetrusor injection of BoNT/A, respectively. Median duration of effect of treatments was 4 and 6 years post-introduction of anticholinergics and BoNT/A, respectively. CONCLUSION: This study describes NLUTD journey of patients with SCI demonstrating the mid-term efficacy of the two first therapeutic lines of NDO management. An improvement of non-surgical therapeutics is needed.

RESUMEN

PURPOSE: This study aimed to determine the long-term effectiveness of augmentation ileocystoplasty (AI) associated with supra-trigonal cystectomy on clinical and urodynamic variables, and the safety of the intervention in individuals with spinal cord injury (SCI). MATERIALS AND METHODS: Single-center, retrospective study of all patients with SCI who underwent AI with supra-trigonal cystectomy from January 1994, with a follow-up of more than 8 years. The primary outcome was the sustained long-term effectiveness of AI with supra-trigonal cystectomy on clinical and urodynamic variables. The secondary outcome was the long-term safety of this procedure. RESULTS: We included 77 patients: 57% were female, mean (SD) age was 52.0 (13.0) years, 77% had paraplegia, and median time since onset was 25.0 [19; 30] years. Long-term success rate (evaluated 13 [10; 15] years post AI) was 93.5% for urodynamic parameters and 76.6% for urinary incontinence. Results of the short- and long-term post-AI assessments did not differ for any urodynamic or clinical variables. Bladder lithiasis occurred in 20.5% of cases and ≥ 1 febrile urinary tract infection occurred in 55.8%, mostly within the first 2 years of follow-up. No cases of bladder cancer were diagnosed. CONCLUSION: AI associated with supra-trigonal cystectomy in patients with SCI is safe and effective in both the short term and long term. Regular urodynamic assessment is not necessary in clinically stable patients with low bladder risk; however, close monitoring is important because of the risk of urological complications.

RESUMEN

PURPOSE: The aim of this work was to mechanically characterize a specific active guidewire and catheters that are commercially available, for further implementation into numerical simulation of endovascular navigation towards complex targets. METHODS: For the guidewire, 3-point bending tests and bending with added masses were used to obtain the Young moduli of its various components. To study its behavior, the guidewire was activated under "ideal" conditions and its performance was investigated. As for the various catheters, they were measured and 3-point bending tests were conducted to determine their mechanical properties. RESULTS & CONCLUSION: The Young moduli of the shaft and the distal tip of the guidewire were determined. We defined a suitable current intensity to activate the guidewire related to an optimal curvature. Then, the time of activation/deactivation was measured at 1.7 s. On the flip side, parts of the catheters were considered either elastic or viscoelastic. In all cases, the rigidity gradients along the various catheters were highlighted. The characterization of the aforementioned surgical tools provides the opportunity to simulate the endovascular nagivation process.

RESUMEN

Neurogenic bladder and sexual dysfunction after spinal cord lesions are highly prevalent. The treatment algorithm for neurogenic bladder is well described. Clean intermittent self-catheterisation associated with treatment of neurogenic detrusor overactivity is the gold standard. Goals of treatment are twofold: i) control risk factors to avoid upper urinary tract complications, and ii) improve quality of life by treating incontinence when feasible. Lower urinary tract dysfunction is still a major cause of complications and hospitalisation. Sexual dysfunction must be addressed and treated and is at the top of patient expectations one year after injury.

RESUMEN

OBJECTIVE: Saliva is the most important biological factor to protect against erosive tooth wear (ETW). Gastroesophageal reflux disease (GERD) patients have an increased risk of ETW due to the frequent presence of intrinsic acids in the oral cavity. Remarkably, not all GERD patients suffer from ETW, which might be due to differences in the composition of the saliva. METHODS: This study compared the proteomic profile of saliva in patients (1) with GERD and ETW (basic erosive wear examination, BEWE, score ≥9; GE group) and (2) with GERD without ETW (BEWE = 0; GNE group) using shotgun label-free quantitative proteomic analysis nLC-ESI-MS/MS. The ability of hemoglobin (Hb) to protect against initial enamel erosion caused by a daily 10-s immersion of enamel specimens in 0.01 M HCl (pH 2.3) for 3 days was evaluated in vitro for proof of concept. Surface hardness change was used as response variable. RESULTS: The differential expression of Hb subunits was significantly increased in the GNE group versus the GE group, in particular the Hb α-subunit that showed a >22-fold increase. Expressions of serum albumin (4.5-fold) and isoforms of cytoskeletal keratin type II (>3-fold) were also increased in the GNE group. Proteinase inhibitors, such as α1-antitrypsin and α2-macroglobulin, were only identified in the GNE group. In vitro, Hb (1.0 and 4.0 mg/mL) significantly reduced initial enamel erosion compared to a negative control after 3 days. CONCLUSIONS: Our results indicate that many proteins, with special emphasis on Hb, may be involved in the resistance of GERD patients to the occurrence of ETW. These proteins may be candidates for inclusion in dental products to protect against ETW.

RESUMEN

Micro light emitting diodes have been grown by metal organic vapor phase epitaxy on standard GaN and partly relaxed InGaNOS substrates with the purpose of incorporating higher concentrations of indium for identical growth conditions. Green emission has been demonstrated at wavelengths of 500 nm for the GaN template and 525 and 549 nm for the InGaNOS substrates, respectively. The structure, deformation, indium concentration and piezoelectric potentials have been measured with nm-scale spatial resolution in the same specimens by transmission electron microscopy. We show by off-axis electron holography that the piezoelectric potential and information about the indium concentration from the mean inner potential are obtained simultaneously. By separating the components using a model, we show that for higher concentrations of indium in the quantum wells (QWs) grown on InGaNOS substrates, the piezoelectric potentials are reduced. The measurements of the indium concentrations by electron holography have been verified by combining energy dispersive x-ray spectrometry, x-ray diffraction and from the tensile deformation made by precession electron diffraction. A discussion of the limitations of these advanced aberration-corrected transmission electron microscopy techniques when applied to nm-scale QW structures is given.

RESUMEN

PURPOSE: Management of pregnancy and delivery in women with lower urinary tract reconstruction is challenging and the currently available literature is insufficient to guide clinical practice. We report pregnancy and delivery outcomes in this specific population. MATERIALS AND METHODS: We conducted a national multicenter retrospective study (16 centers) including 68 women with 96 deliveries between 1998 and 2019. These women had at least 1 successful pregnancy and delivery after augmentation enterocystoplasty, catheterizable channel creation and/or artificial urinary sphincter implantation. Maternal and fetal complications during pregnancy and delivery were reported, as well as postpartum functional outcomes, according to the delivery mode. The chi-square test and Student's t-test were used to compare categorical and continuous variables, respectively. RESULTS: Overall 32% of reported pregnancies were complicated by febrile urinary tract infections, 13.5% by renal colic and 14.6% required upper urinary tract diversion. In addition, 10% of patients reported transient self-catheterization difficulties and 13.5% reported de novo or increased urinary incontinence. The preterm delivery rate was 35.3%. Elective C-section was performed in 61% of pregnancies. Twenty complications occurred during delivery (20%), including 19 during elective C-section. Urinary continence at 1 year was unchanged for 93.5% of deliveries. Delivery mode (p=0.293) and multiparity (p=0.572) had no impact on urinary continence. CONCLUSIONS: In this population C-section appeared to be associated with a high risk of complications. In the absence of any obstetric or neurological contraindications, vaginal delivery should be proposed as the first line option to the majority of these women.

RESUMEN

INTRODUCTION: Our objective was to provide guidelines covering all aspects of intermittent catheterisation (intermittent self-catheterisation and third-party intermittent catheterisation). MATERIALS AND METHODS: A systematic review of the literature based on Pubmed, Embase, Google scholar was initiated in December 2014 and updated in April 2019. Given the lack of robust data and the numerous unresolved controversial issues, guidelines were established based on the formal consensus of experts from steering, scoring and review panels. RESULTS: This allowed the formulation of 78 guidelines, extending from guidelines on indications for intermittent catheterisation, modalities for training and implementation, choice of equipment, management of bacteriuria and urinary tract infections, to the implementation of intermittent catheterisation in paediatric, geriatric populations, benign prostatic hyperplasia patients and continent urinary diversion patients with a cutaneous reservoir as well as other complications. These guidelines are pertinent to both intermittent self-catheterisation and third-party intermittent catheterisation. CONCLUSION: These are the first comprehensive guidelines specifically aimed at intermittent catheterisation and extend to all aspects of intermittent catheterisation. They assist in the clinical decision-making process, specifically in relation to indications and modalities of intermittent catheterisation options. These guidelines are intended for urologists, gynaecologists, geriatricians, paediatricians, neurologists, physical and rehabilitation physicians, general practitioners and other health professionals including nurses, carers….

RESUMEN

PURPOSE: We report the natural history and prognosis of tumors after augmentation enterocystoplasty, with a molecular analysis using an oncogene panel to search for potential targeted therapies. MATERIALS AND METHODS: This multicenter, nationwide, retrospective study included 16 patients. A panel of 21 clinically relevant oncogenes was tested on archival tumor specimens using next-generation sequencing. Survival rate was the main clinical outcome and sequences were compared to the reference genome for the genetic outcome. RESULTS: Augmentation enterocystoplasties were performed mainly for congenital neurogenic bladder and bladder exstrophy at a median patient age of 17 years (range 4 months to 45 years). Most of the malignancies were diagnosed because of clinical manifestations, with a median latency period of 20 years. Adenocarcinomas were mainly found after gastrocystoplasty, whereas urothelial cell carcinomas were typically found after colocystoplasty. Of the 16 patients 13 were diagnosed at an advanced stage of the disease (positive lymph nodes in 7, distant metastases in 6). The overall 1-year survival rate was 56%. Only 3 patients remained disease-free at a median followup of 70 months. Of the 9 tumors with analyzable DNA 4 were wild-type and 5 harbored missense mutations (KIT-p.Pro573Ser, PDGFRA-p.Glu587Lys, KRAS-p.Gly12Asp, ERBB4p.Arg484Lys, CTNNB1-p.Ser37Phe and p.Ser47Asn). CONCLUSIONS: Malignancy after augmentation enterocystoplasty is diagnosed late with frequent metastases and a very low 1-year survival rate. More than half the tested samples harbored missense mutations in oncogenes accessible to targeted therapies. An international collaboration to enlarge the genetic panel analysis of these tumors may offer new therapeutic hope to patients.

RESUMEN

Urinary tract infections (UTIs) in patients with neurogenic bladder are a major public health issue due to their high incidence and major consequences. Despite their frequency and potential severity, their physiopathology and management are poorly known. We provide a narrative literature review on the epidemiology, physiopathology, diagnostic criteria, microbiology, antimicrobial management, and prevention. UTIs among patients with neurogenic bladder are associated with high morbidity and healthcare utilization. Risk factors for UTI among this population are: indwelling catheter, urinary stasis, high bladder pressure, and bladder stones. Their diagnosis is a major challenge as clinical signs are often non-specific and rare. A urinary sample should be analyzed in appropriate conditions before any antibiotic prescription. According to most guidelines, a bacterial threshold≥103CFU/ml associated with symptoms is acceptable to define UTI in patients with neurogenic bladder. The management of acute symptomatic UTI is not evidence-based. A management with a single agent and a short antibiotic treatment of 10 days or less seems effective. Antibiotic selection should be based on the patient's resistance patterns. Asymptomatic bacteriuria should not be treated to avoid the emergence of bacterial resistance. Regarding preventive measures, use of clean intermittent catheterization, intravesical botulinum toxin injection, and prevention using antibiotic cycling are effective. Bacterial interference is promising but randomized controlled trials are needed. Large ongoing cohorts and randomized controlled trials should soon provide more evidence-based data.

RESUMEN

PURPOSE: Urinary tract infection (UTI) is the most common complication in patients with neurogenic bladder. The long-term use of antibiotic drugs induces an increase in antimicrobial resistance and adverse drug reactions. Bacterial interference is a new concept to prevent recurrent UTI which consists in a bladder colonization with low virulence bacteria. We performed a literature review on this emerging therapy. MATERIALS AND METHODS: Literature review of bacterial interference to prevent symptomatic urinary tract infection in neurological population. RESULTS: Seven prospectives study including 3 randomized, double-blind and placebo controlled trial were analyzed. The neurological population was spinal cord injured in most cases. The bladder colonization was performed with 2 non-pathogen strains of Escherichia coli: HU 2117 and 83972. At 1 month, 38 to 83% of patients were colonized. Mean duration of colonization was 48.5 days to 12.3 months. All studies showed that colonization might reduce the number of urinary tract infections and is safe with absence of serious side effects. CONCLUSION: Bacterial interference is a promising alternative therapy for the prevention of recurrent symptomatic urinary tract infections in neurogenic patients. This therapy should have developments for a daily use practice and for a long-term efficacy.

RESUMEN

OBJECTIVE: Changes in the protein profile of acquired enamel pellicles (AEP) formed in vivo over different time periods were evaluated after the application of hydrochloric acid (HCl). METHODS: Nine subjects were submitted to dental prophylaxis with pumice. After 3 or 120 min, the teeth were isolated with cotton rolls and 50 µL of 0.1 M HCl (pH 1.0), 0.01 M HCl (pH 2.0), or deionized water were applied on the buccal surface of the teeth for 10 s. The AEP was then collected using an electrode filter paper presoaked in 3% citric acid. After protein extraction, the samples were submitted to reverse-phase liquid chromatography coupled to mass spectrometry (nano LC-ESI-MS/MS). Label-free quantification was performed (Protein Lynx Global Service software). RESULTS: A total of 180 proteins were successfully identified in the AEP samples. The number of identified proteins increased with the time of pellicle formation. Only 4 proteins were present in all the groups (isoforms of IgA, serum albumin, and statherin). The greatest number of proteins identified uniquely in one of the groups was obtained for the groups treated with HCl after 2 h of pellicle formation (approx. 50 proteins). CONCLUSION: Proteins resistant to removal by HCl, such as serum albumin and statherin, were identified even in the short-term AEP. In addition, 120-min pellicles present many proteins that are resistant to removal by HCl. This suggests an increase in protection against intrinsic acids with the time of pellicle formation, which should be evaluated in future studies.

RESUMEN

STUDY DESIGN: A retrospective observational study. OBJECTIVE: To describe specificities of pregnancy in a traumatic spinal cord-injured (SCI) population managed by a coordinated medical care team involving physical medicine and rehabilitation (PMR) physicians, urologists, infectious diseases' physicians, obstetricians and anaesthesiologists. SETTING: NeuroUrology Department in a University Hospital, France. METHODS: All consecutive SCI pregnant women managed between 2001 and 2014 were included. A preconceptional consultation was proposed whenever possible. Obstetrical and urological outcomes, delivery mode and complications were reported. RESULTS: Overall, thirty-seven pregnancies in 25 women, of a mean age of 32±4 years, were included. Thirty-five children were born alive (three miscarriages, a twin pregnancy) without complications except for a case of neonatal respiratory distress in premature twins born at 33 weeks. The mean birth weight was 2979±599 g. Twenty-one (57%) pregnancies benefited from preconceptional care. A weekly oral cyclic antibiotic programme was prescribed in 28 (75%) pregnancies. The main complications during pregnancy included pyelonephritis (30%), lower urinary tract infections (UTI) (32%), pressure sores (8.8%) and prematurity (12% deliveries before 37 weeks, with only one delivery before 36 weeks). Two patients suffered from autonomic dysreflexia, one with serious complication (brain haematoma). Caesarean sections were performed for 68% of deliveries (23/34) to prevent syringomyelia deterioration (n=10), stress urinary incontinence aggravation (n=3) or for obstetrical reasons (n=7). CONCLUSIONS: Mothers' and infants' outcomes were satisfying after pregnancy in SCI women, but required many adjustments. Pregnancy must be prepared by a preconceptional consultation, and managed by a multidisciplinary team involving specialists of neurological disability and pregnancy.

RESUMEN

OBJECTIVES: Patients presenting with neurogenic bladder often require urological procedures (urodynamic testing and botulinum toxin injections) and a preventive antibiotic therapy. We aimed to assess the efficacy of this little known strategy in a cohort of patients. PATIENTS AND METHODS: All patients presenting with neurogenic bladder who underwent urological procedure were included in the study. They received an antibiotic therapy in accordance with the urine cytobacteriological examination results. The antibiotic therapy was initiated two days before the procedure and prolonged up until two days after the procedure if the culture was positive. Patients were treated with a single dose of fosfomycin-trometamol in case of a negative culture. The main study outcome was the occurrence of urinary tract infection (UTI), defined by a positive urine culture and symptoms, up until 14 days after the procedure. RESULTS: A total of 80 urological procedures were performed. Mean patient age was 47±13.1 years (sex ratio 1.22); 59 (73.8%) presented with asymptomatic bacteriuria before the procedure. Nine (11.1%) UTIs were recorded on Day 14, of which one (1.2%) was febrile. Two patients required an additional curative antibiotic therapy. No patient was hospitalized. Overall, 77.8% of UTIs were cured without antibiotic therapy. CONCLUSION: Screening and treating asymptomatic bacteriuria before urological procedures seems unnecessary and vainly exposes this population at high risk of infectious diseases to antibiotic therapies. This data should be confirmed by a randomized clinical trial.

RESUMEN

OBJECTIVES: Specify urinary functional impairment associated with diabetic pathology. Propose guidance for screening, monitoring of clinical signs of lower urinary tract (LUTS) and describe the specifics of the urological treatment of patients. METHODS: A review of literature using PubMed library was performed using the following keywords alone or in combination: "diabetes mellitus", "diabetic cystopathy", "overactive bladder", "bladder dysfunction", "urodynamics", "nocturia". RESULTS: LUTS are more common in the diabetic population with an estimated prevalence between 37 and 70 %, and are probably underevaluated in routine practice. They are heterogeneous and are frequently associated with other diabetic complications. Both storage and voiding symptoms can coexist. Despite a major evaluation in the literature, no recommendation supervises the assessment and management of LUTS in this specific population. An annual screening including medical history, bladder and kidney ultrasound and post-void residual measurement is required in the follow-up of diabetic patients. Specific urologial referral and urodynamic investigations will be performed according to the findings of first-line investigations. The type of bladder dysfunction, the risk of urinary tract infections and dysautonomia should be considered in the specific urological management of these patients. CONCLUSION: Diabetes mellitus significantly impacts on the lower urinary tract function. A screening of LUTS is required as well as other complications of diabetes. The management of LUTS must take into consideration the specific risks of the diabetic patient regarding the loss of bladder contractility, the possibility of dysautonomia and infectious complications.

RESUMEN

OBJECTIVE: There is currently no guideline regarding the management of neurogenic detrusor overactivity (NDO) refractory to intra-detrusor botulinum toxin injections. The primary objective of the present study was to find a consensus definition of failure of botulinum toxin intra-detrusor injections for NDO. The secondary objective was to report current trends in the managment of NDO refractory to botulinum toxin. METHODS: A survey was created, based on data drawn from current literature, and sent via e-mail to all the experts form the Group for research in neurourology in french language (GENULF) and from the comittee of neurourology of the French urological association (AFU). The experts who did not answer to the first e-mail were contacted again twice. Main results from the survey are presented and expressed as numbers and proportions. RESULTS: Out of the 42 experts contacted, 21 responded to the survey. Nineteen participants considered that the definition of failure should be a combination of clinical and urodynamics criteria. Among the urodynamics criteria, the persistence of a maximum detrusor pressure>40 cm H2O was the most supported by the experts (18/21, 85%). According to the vast majority of participants (19/21, 90.5%), the impact of injections on urinary incontinence should be included in the definition of failure. Regarding the management, most experts considered that the first line treatment in case of failure of a first intra-detrusor injection of Botox(®) 200 U should be a repeat injection of Botox(®) at a higher dosage (300 U) (15/20, 75%), regardless of the presence or not of urodynamics risk factors of upper tract damage (16/20, 80%). CONCLUSION: This work has provided a first overview of the definition of failure of intra-detrusor injections of botulinum toxin in the management of NDO. For 90.5% of the experts involved, the definition of failure should be clinical and urodynamic and most participants (75%) considered that, in case of failure of a first injection of Botox(®) 200 U, repeat injection of Botox(®) 300 U should be the first line treatment.
