RESUMO
OBJECTIVES: To describe a concept of standardized preoperative one-day evaluation before urinary reconstructive or diversion surgery for the treatment of neurogenic lower urinary tract (LUT) dysfunction, and to evaluate its feasibility and its impact on the care pathway. MATERIALS AND METHODS: All patients who underwent a one-day standardized evaluation before a urinary reconstructive or derivation surgery for the treatment of neurogenic LUT dysfunction between January 2017 and December 2021 in our institution were included. Data were collected retrospectively from standardized reports. The main outcome was the rate of completion of the tests and consultations planned during this evaluation. Secondary outcomes included the findings from the one-day evaluation and changes in the urological surgical strategy at different time points within one year. RESULTS: One hundred and thirty-one patients benefited from this one-day standardized evaluation. The overall completeness rate of the data collected was 77.5%, increasing from 62.3% in 2017 to 89.3% in 2021. The urological surgical plan was modified for 19.1% of patients following this preoperative evaluation. The indication was then confirmed for 114 patients (87.0%) by the multidisciplinary meeting and was carried out unchanged during the following year for 89 patients (67.9%). An associated colostomy procedure was proposed for 18.3% of patients and was finally performed in 11.5%. CONCLUSION: A standardized multidisciplinary preoperative one-day evaluation before performing reconstructive or diversion surgery for the treatment of neurogenic LUT dysfunction seems feasible and makes it possible to optimize the surgical plan and adapt the course of care.

AIM: To assess the efficacy of switching to Abobotulinumtoxin A (ATA) intradetrusor injections (IDI) after failure of Onabotulinumtoxin A (OTA) IDI for the treatment of neurogenic detrusor overactivity in patients with spinal cord injury (SCI). MATERIALS AND METHODS: A single-centre retrospective chart review study. All SCI patients who started OTA IDI after 2011 and had an ATA IDI switch were included. The primary outcome was the clinical and urodynamic efficacy of the switch to ATA IIDs at the last follow-up. Secondary outcomes were initial efficacy, duration of ATA treatment, and patient outcome including the occurrence of augmentation enterocystoplasty at last follow-up. RESULTS: Sixty-two patients were included. Eighteen patients (28.9%) were initially responders to ATA IDI. Nine patients (14.5%) remained responders at last follow-up after a median of 17 months (AE 8.8-29). Thirty-two patients (51.6%) had had or were awaiting augmentation enterocystoplasty with a follow-up time of 18.5 months (IQR 8-27). Eleven patients (17.7%) were on ATA IDI with low efficacy. Seven patients (11.3%) were switched back to OTA and 3 patients (4.8%) changed their voiding pattern. CONCLUSION: Switching from OTA to ATA toxin for IDI in the treatment of detrusor overactivity after spinal cord injury have long-term efficacy for a limited number of patients but may delay the need for surgery.

Asthma is a frequent respiratory disease, with severe asthma occurring in 3 to 5% of cases. Chronic inflammation of the bronchial epithelium is essential to its pathophysiology. When activated by the bronchial environment, the peripheral sensory nervous system contributes to inflammation of the airways. However, due to a lack of reliable models, the mechanisms of action remain largely unknown. Using induced pluripotent stem cells reprogrammed from blood cells, we have set up a model of bronchial epithelium innervated by sensory neurons. This model will ensure better understanding of the mechanisms of action underlying neurogenic inflammation.

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.

AIMS: Evaluation of repeated (at least 4) intra-detrusor injections of toxin botulinum A (IDI-TBA) for neurogenic bladder in a pediatric cohort. METHODS: Patients who underwent at least 4 IDI-TBA between 2005 and 2017 for neurogenic bladder related issues were included (detrusor overactivity and low compliance). Clinical and cystometric data were collected before and after the first injection and after the last injection. The primary endpoint was the proportion of patients with non-abnormal cystometry (no detrusor overactivity and normal compliance). Secondary outcomes were the evolution of the observed bladder capacity/expected ratio, surgical complications and acquired kidney impairment. RESULTS: From the 832 patients referred to our institution for neurogenic bladder, 48 underwent IDI-TBA, and 17 at least 4 injections. Among them, a total of 95 procedures were performed (median per patient 5 [4-8]). While the first injection had a significant effect for 82.3% patients, the last injection improved the medical condition for only 53.0% cases. The bladder capacity ratio, initially 36.1%, increased to 80.3% after the first injection but decreased to a level of 57.1% at last. After a median follow-up of 57 [34-102] months, no severe complications were reported but 11.8% of patients presented with repeated pyelonephritis. A bladder augmentation surgery was finally indicated for 35.3% cases. CONCLUSIONS: Despite a low complication rate and impressive cystometric results after the first injection, IDI-TBA efficacy decreased with time and repetition. These findings prone a long-term follow-up and a "à-la-carte" management of this specific population depending on the long-term response to IDI-TBA.

Neurogenic heterotopic ossifications (NHOs) are periarticular ectopic ossifications that frequently develop after a central nervous system injury, most often a traumatic one. They limit range of motion and cause pain, interfering with limb positioning and function, whether active or passive. Highly described in the lower limbs, NHOs can also develop in the upper limb, with specific characteristics depending on their location. This article provides a summary of the diagnostic and therapeutic management of NHOs in the upper limb, based on the current literature.

BACKGROUND: The clinicopathological value and exploration of the potential molecular mechanism of microRNA-183-5p (miR-183-5p) have been investigated in various cancers. This study further explored the transcriptome profile regulated by miR-183-5p. METHODS: Messenger RNA (mRNA) expression data, miRNA expression, and clinical information of stomach adenocarcinoma (STAD) were downloaded from The Cancer Genome Atlas (TCGA) database. Differentially expressed genes (DEGs) that related to mir-189-5p expression and cancer proliferation were acquired using bioinformatics analysis. The biological functions of these genes were analyzed in terms of Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG). Hub genes relating to gastric cancer (GC) signal pathway were explored. The results were validated by further experiments. RESULTS: A total of 308 genes were found to be regulated by miR-183-5p, and they were related to cancer and GC patients' survival outcome. The biological function of these genes was found to act mainly on biological processes and the involved signal pathways included neuroactive ligand-receptor interaction, cell adhesion molecules, and axon guidance. In addition, miR-183-5p was also shown to regulate the mTOR, Wnt, MAPK, and PI3K-Akt signaling pathways through the genes WNT2B, NGFR, and NTRK2. CONCLUSIONS: The miRNA miR-183-5p participates in the tumorigenesis and development of GC via certain signaling pathways, in particular the nerve- and immunity-related genes.
RESUMO
Spinal stenosis can be found in up to 80 % of individuals aged over 70 years. However, about 20 % of asymptomatic individuals demonstrate signs of spinal stenosis on MRI. The pathomechanism of central spinal stenosis is predominantly related to degenerative changes. Those eventually result in a progressive compression of the cauda equina. Patients who exhibit mild to moderate symptoms should undergo multimodal conservative treatment, such as patient education, pain medication, physiotherapy and epidural injections. Surgery should be evaluated in patients with severe symptoms, especially if conservative treatment fails after 36 months of trial. Clinically relevant motoric deficits or symptoms of cauda equina syndrome remain absolute indications for surgery.

INTRODUCTION: The temporary prosthetic sphincterotomy is a possible treatment for neurologic detrusor sphincter dyssynergia (DSD). The purpose of the study was to verify the feasibility and effectiveness of the urethral stent (US) Temporary ALLIUM BUS "BULBAR URETHRAL STENT". PATIENTS AND METHODS: A prospective, non-comparative, single-center starting in 2015 was conducted. Were included patients over 18 years, with a neurologic DSD proved urodynamically for which medical treatment was not indicated or failed. The primary endpoint was the percentage of patients who had a voiding method considered as improved or much improved at 1 month and the feasibility of the procedure. RESULTS: From January to June 2015, 7 patients, (mean age 47.9 years [24-76 years]) were prospectively enrolled. One patient was lost to sight at one month and therefore excluded. The median follow-up was 8.1 months (1-10 months). All procedures were technically successful. At 1 month, there were 57% of grade 2 complications (Clavien-Dindo), 1 of 6 patients had a migration of the US. At one month, quality of life and the urologic situation was considered good in 3 patients, unchanged in 2 patients and decreased in 1 patient. The study was stopped after the inclusion of seven patients. At the date of the latest news, 5 of 6 patients had a migrated or an explanted US. CONCLUSION: The temporary urethral stent ALLIUM BUS does not seem to be a possible surgical alternative for the treatment of detrusor sphincter dyssynergia. LEVEL OF EVIDENCE: 4.

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.

INTRODUCTION: For the last ten years, botulinum neurotoxin type A has become the gold standard for the treatment of neurogenic overactive detrusor. Bacterial colonization is common for these patients using clean intermittent self-catheterization, and toxin injections are at risk of urinary tract infections. OBJECTIVES: The aim of our study was to determine the prevalence of different germs and their resistance to antibiotics in patients with neurogenic bladder, treated with intravesical botulinum toxin injections. MATERIAL AND METHOD: This epidemiologic study took place from September to October 2012 in a urodynamic and neurourology unit in a teaching hospital in Paris, France. RESULTS: Eighty patients with a valid urine culture according to our protocol, were included. Fourty-four culture were positive with 45 bacteria. We found an Escherichia coli in 42.5%, a Klebsiella pneumoniae in 7.5%, a Citrobacter freundii and an enterococcus in 2.5%, and a Staphylococcus aureus in 1.25%. Penicillin resistance were found in 51.11%, 3rd generation cephalosporins in 8.89%, quinolones in 28.89% and sulfamids in 24.44%. None were resistant to fosfomycin. CONCLUSION: E. coli was the most frequent bacterium. No resistance to fosfomycin was found.

The present article demonstrates an unusual case of bilateral massive peripheral edema caused by neurogenic areflexic bladder in diabetes mellitus type 1. A 28-year-old patient with diabetes type 1 treated for a number of years was referred to the department of internal medicine because of massive edema of his lower limbs. Blood samples revealed increased concentrations of glucose (21.2 mmol/L) and glycated hemoglobin (8.5%). The computed tomography examination of abdomen and pelvis confirmed enlargement of the bladder, with smooth external contour and normal wall thickness. In addition, computed tomography demonstrated bilateral compression of the iliac veins caused by the enlarged bladder. This case highlights the importance of keeping a broad differential diagnosis in mind for patients with diabetes and massive peripheral edema. Neurogenic bladder should be considered in the differential diagnosis, especially for patients with poor glycemia control and long-standing diabetes complicated by diabetic neuropathy.

OBJECTIVE: Review the literature on therapeutic strategies and guidelines for the treatment of neurogenic bladder in multiple sclerosis. MATERIAL AND METHOD: A search on available articles on consensus, recommendations guidelines and algorithm of treatment of urinary tract dysfunction in multiple sclerosis. RESULTS: Five national consensus guidelines were recently published and proposed guidelines for the first and second line treatments. CONCLUSION: Multiple sclerosis patients suffering from lower urinary tract disorders must benefit from an early diagnosis and simple first line evaluation and treatment. More complex and invasive evaluation in the neuro-urology unit is appropriate for patients who failed to first line treatment or in case of complications.

La artropatía neuropática de Charcot es muy rara en niños. Este trabajo tiene como propósito fundamental presentar el tratamiento seguido en un infante con esta enfermedad. Se presenta un escolar masculino de seis años de edad y raza negra, procedente de La Habana que es traído al Complejo Científico Ortopédico Internacional Frank País por presentar aumento de volumen y deformidad del tobillo y el pie izquierdo de más de seis meses de evolución. Se muestran los hallazgos de laboratorio clínico (todos dentro de valores normales) e imagenológicos (radiografías, tomografía axial computarizada y gammagrafía ósea), así como el tratamiento impuesto (conservador y quirúrgico). Seis meses posteriores al diagnóstico se logró la remodelación del tobillo y la curación de las úlceras del pie izquierdo. Pero un año más tarde, apareció un cuadro similar en el derecho tras un trauma escolar. El caso presentado, inusual por la edad del paciente al momento del diagnóstico, nos demuestra lo difícil y complejo que resulta el tratamiento de la artropatía neuropática de Charcot y la necesidad de su seguimiento continuo y activo(AU)
Charcot neuropathic arthropathy is very rare in children. The present paper is mainly aimed at presenting the treatment applied to a child suffering from this disease. A black six-year-old school boy is brought to Frank País International Scientific Orthopedic Complex with enlargement and deformity of his left ankle and foot of more than six months' evolution. Clinical laboratory results (all within normal ranges) and imaging findings (radiography, computerized axial tomography and bone scintigraphy) are provided. The treatment indicated (conservative and surgical) is described. Six months after diagnosis the ankle had been remodeled and the ulcers on the left foot had healed. However, a year later a similar situation presented, now on the right foot, as a result of a trauma in school. The case presented, unusual as it is due to the patient's age at diagnosis, illustrates the difficulty and complexity of the treatment of Charcot neuropathic arthropathy, and the need for permanent, active follow-up(AU)
L'arthropathie neurogène de Charcot est une affection très rare chez les enfants. Le but de ce travail est de présenter le traitement de la neuro-arthropathie de Charcot chez un enfant. Un écolier âgé de 6 ans et de la race noire, provenant de La Havane, est vu en consultation au Centre scientifique orthopédique international Frank Pais , dû à une augmentation du volume et une difformité de sa cheville et son pied gauches avec plus de six mois d'évolution. Les résultat du laboratoire clinique (en normalité) et d'imagerie (radiographies, tomographie axiale informatisée et gammagraphie osseuse), ainsi que le traitement indiqué (conservateur et chirurgical), sont montrés. Six mois après le diagnostic, le remodelage de la cheville et la guérison des ulcères du pied gauche sont réussis. Un an après un tableau similaire apparaît, mais au pied droit. Le cas présenté, peu fréquent chez un enfant, nous montre combien le traitement de l'arthropathie neurogène est difficile et complexe, et combien un suivi continue et actif est nécessaire dans ces cas(AU)
