Azithromycin and moxifloxacin resistance determinants in Mycoplasma genitalium in Lleida, Spain.

OBJECTIVE: Mycoplasma genitalium (MG) is a microorganism related to sexually transmitted infections. Antibiotic resistance of MG leads to an increase in treatment failure rates and the persistence of the infection. The aim of this study was to describe the most frequent mutations associated with azithromycin and moxifloxacin resistance in our geographical area. METHODS: A prospective study from May 2019 to May 2023 was performed. MG-positive samples were collected. Real-time PCRs (AllplexTM MG-AziR Assay and AllplexTM MG-MoxiR Assay, Seegene) were performed in MG positive samples to detect mutations in 23S rRNA V domain and parC gene. RESULTS: A 37.1% of samples presented resistance determinants to azithromycin and the most common mutation detected was A2059G (57.9%). Resistance to moxifloxacin was studied in 72 azithromycin-resistant samples and 36.1% showed mutations, being G248T the most prevalent (73.1%). CONCLUSIONS: The resistance to different lines of treat ment suggests the need for a targeted therapy and the performing of a test of cure afterwards.

Efficacy of sacral transcutaneous electrical nerve stimulation in patients with overactive bladder refractory to anticholinergic treatment: a prospective multi-center study. / Eficacia de la electroestimulación transcutánea sacra en pacientes con vejiga hiperactiva refractarios a fármacos anticolinérgicos. Estudio prospectivo y multicéntrico.

OBJECTIVE: To determine whether sacral transcutaneous electrical nerve stimulation (S-TENS) is an effective treatment in patients refractory to anticholinergic drugs (Achs). MATERIALS AND METHODS: A prospective multi-center study of patients with overactive bladder (OB) refractory to Achs treated with S-TENS from 2018 to 2021 was carried out. S-TENS was applied over 3 months. Symptom progression was assessed using the voiding calendar and the Pediatric Lower Urinary Tract Symptoms Score (PLUTSS), excluding questions 3 and 4 -referring to enuresis- so that progression of daytime symptoms only (LUTS variable) was analyzed. RESULTS: 66 patients -50% of whom were female- were included, with a mean age of 9.5 years (range: 5-15). S-TENS significantly lowered PLUTSS (19.1 baseline vs. 9.5 final, p< 0.001) and LUTS (13.1 baseline vs. 4.8 final, p< 0.001). It also reduced the number of mictions (8.5 baseline vs. 6.4 final, p< 0.001), while increasing urine volume in the voiding records (214 ml baseline vs. 258 ml final, p< 0.001). Enuresis was the only variable refractory to S-TENS. Complication rate was 3% (2 patients with dermatitis in the S-TENS application area). CONCLUSIONS: S-TENS is effective and safe in the short-term in patients with OB refractory to Achs. Further studies assessing long-term efficacy and potential relapses are required.

OBJETIVOS: Determinar si la electroterapia nerviosa transcutánea a nivel sacro (TENS-S) es un tratamiento efectivo en pacientes refractarios a fármacos anticolinérgicos (Ach). MATERIAL Y METODOS: Estudio prospectivo y multicéntrico: pacientes con VH refractaria a Ach tratados con TENS-S entre 2018-2021. El TENS-S se aplicó durante 3 meses. La evolución sintomática fue evaluada utilizando el calendario miccional y el cuestionario PLUTSS (Pediatric Lower Urinary Tract Symptoms Score), pero excluyendo sus preguntas 3 y 4 (referidas a la enuresis) para analizar solamente la evolución de la sintomatología diurna (variable LUTS). RESULTADOS: Fueron incluidos 66 pacientes (50% niñas), con una edad media de 9,5 años (rango: 5-15). El TENS-S disminuyó significativamente el PLUTSS (19,1 inicial vs 9,5 final, p< 0,001) y el LUTS (13,1 inicial vs 4,8 final, p< 0,001). Además, redujo el número de micciones (8,5 inicial vs 6,4 final, p< 0,001) y aumentó el volumen de orina en los registros miccionales (214 ml inicial vs 258 ml final, p< 0,001). La enuresis fue la única variable refractaria al TENS-S. La tasa de complicaciones fue del 3% (2 pacientes, dermatitis en el área de aplicación del TENS-S). CONCLUSIONES: El TENS-S es efectivo y seguro a corto plazo en pacientes con VH refractarios a los Ach. Deben realizarse estudios para evaluar la eficacia a largo plazo y posibles recaídas.

Distal Urethral Advance and Glanduloplasty (DUAGPI) for Distal Hypospadias: A 15 Years Experience

Background: Meatal advancement with glanduloplasty (MAGPI) has been in the recent years one of the most frequently surgical techniques used for the correction of distal hypospadias. Multiple modifications have been described to improve the results ofthis technique. In 2004 we presented the initial results of the New Modern MAGPI or DUAGPI (distal urethral advancement and glanduloplasty) as a surgical alternative to the original MAGPI. Objetive: The objective of the present study is to evaluate the applicability, safety and the cosmetic results obtained with this technique, as well as the long-term complications. Materials and Methods: Retrospective and descriptive study of patients with distal hypospadias, corrected using the DUAPI technique, between 2002 and 2018. Surgical technique: Initially, an artificial erection was performed, the absence of curvature in all patients is proven. A skin denudation was performed up to the base of the penis in those children with a bend greater than 30. Second, the distal urethral disconnection was performed at the posterior and lateral urethral level. A glandular triangular section is made to accommodate the distal urethra and to allow a conical appearance with a final glandular. Finally, the fixation of the distal urethral to the glandular tip and the anterior glandular closure is performed. We performed an annual follow-up of all patients. The analysis of all the variables collected during surgery and follow-up was done with SPSS 22 statistical package. Results: 90 patients meet inclusion criteria and were included in the study (32 glandular and 58 coronal). The mean surgical time was 47 minutes (Range: 37-71 minutes). The mean follow-up was 9.4 years (2.1-15 years). 2 patients had meatal stenosis after surgery, 4 mild glandular retraction, and 2 urethrocutaneous fistula. Six of the 8 patients with a complication were successfully reoperated (AU)

Puesta al día en electroestimulación vesical y vejiga neurógena en pediatría: una revisión sistemática / Update on vesical electrostimulation and neuropatic bladder in pediatrics: A sistematic review

Introducción y objetivo: La electroestimulación vesical ha surgido como nueva alternativa en el manejo de pacientes adultos con disfunciones vesicales de origen neuropático. A pesar de que numerosos trabajos han probado la eficacia y la seguridad de esta terapia en este grupo de edad, todavía son escasos los estudios que demuestran su éxito en la vejiga neuropática pediátrica. Material y métodos. Realizamos una revisión sistemática de los estudios que evalúan el impacto de la electroestimulación vesical en pacientes pediátricos (0-18 años) con vejiga de origen neurógeno. La búsqueda identificó 9.716 artículos potencialmente elegibles. Finalmente, 11 trabajos publicados entre 1992 y 2019 cumplieron los criterios necesarios para formar parte del estudio y fueron seleccionados para la presente revisión sistemática. Resultados: No encontramos una tendencia común entre los resultados obtenidos de los estudios incluidos en la presente revisión. A pesar de que la mayoría de ellos demostró individualmente una tasa de eficacia óptima y una alta seguridad, la superioridad de esta terapia frente a los fármacos anticolinérgicos no pudo establecerse. Por tanto, hasta la fecha, sus resultados continúan siendo controvertidos. Además, la metodología entre los diferentes estudios fue muy diversa, lo que dificultó la comparación entre los resultados obtenidos de cada uno de ellos. Conclusiones: Dado el potencial riesgo de insuficiencia renal que presentan los pacientes pediátricos con vejiga neurógena, las alternativas terapéuticas utilizadas en su manejo deben tener una eficacia demostrada. Así, ante la ausencia de evidencia con respecto a la electroestimulación vesical en este grupo de pacientes, por el momento su utilización debería ser limitada y excepcional.

Introduction and objective: Bladder neuromodulation has emerged as a new alternative in the management of adults with bladder dysfunctions from a neuropathic origin. Despite the fact that, numerous studies have proven the efficacy and safety of this therapy in adults’ patients, there are however, still few studies that demonstrate its success in paediatric neuropathic bladder. Materials and methods: We perform a systematic review of the studies which analysed the impact of bladder electrostimulation in paediatric patients (0 to 18 years) with a neurogenic origin. The search identified 9716 potentially articles. Finally, 11 papers published between 1992 and 2019 fulfilled the necessary criteria to be part of our study and were selected for the systematic review. Results: We did not find a common trend among the results obtained from the studies included in the present review. Most of the studies demonstrated an optimal efficacy rate and high safety, but however the superiority of this therapy over anticholinergic drugs could not be established due the presented results. For this fact, these results continue to be controversial. Furthermore, the methodology between the different studies was very huge, which made it difficult to compare the results obtained from each one of them. Conclusions: Given the potential risk of renal failure presented by paediatric patients with neurogenic bladder, the therapeutic alternatives used in the management of this disease must have a proven efficacy. For this reason, and after the review, due the absence of evidence regarding bladder electrotherapy in this group of patients, its use should be limited and exceptional.

Improved anaerobic digestion of swine manure by simultaneous ammonia recovery using gas-permeable membranes.

In feedstocks containing high ammonia (NH3) concentration, removal of the NH3 during the anaerobic digestion (AD) process can improve AD process performance. In the present study, the effect of NH3 removal using gas-permeable membrane (GPM) technology on AD process performance and biogas production was investigated using swine manure feedstock. Batch and semi-continuous AD experiments were carried out under mesophilic conditions. In the reactor with NH3 recovery, total ammonia nitrogen (TAN) concentration was reduced 28% in batch experiments and 23% on average in the semicontinuous experiment compared with the reactor without NH3 recovery. Free ammonia (FA) concentrations were also decreased by 23% and 4% on average in batch and semicontinuous experiments, respectively. These reductions in TAN and FA by GPM system positively impacted both the quality and quantity of the biogas produced by AD of swine manure. Specifically, the specific methane yield increased 9% in the batch experiment and 17% on average in the semicontinuous experiment. Furthermore, higher percentages of methane in biogas were obtained during AD retrofitted with GPM system, 24% increase in the batch experiment and 11% on average in the semicontinuous experiment (range 8.3-13.6%). Simultaneously, a uniform TAN recovery rate of 6.7 g N TAN per m2 of membrane and per day was obtained for the 205 days of semicontinuous operation; ammonia nitrogen was recovered in the form of ammonium sulphate solution. Therefore, the AD-GPM configuration produces beneficial results on biogas quantity and quality while recovering ammonia nitrogen in form of ammonium sulphate.

Neuroestimulación eléctrica sacra en la vejiga hiperactiva pediátrica refractaria / Sacral electrical neurostimulation in the refractory pediatric overactive bladder

La incontinencia urinaria es uno de los motivos de visita más frecuentes al urólogo pediátrico, y la vejiga hiperactiva es la disfunción del tracto urinario inferior que más frecuentemente presenta este síntoma. Actualmente, el único fármaco aprobado para el manejo de la vejiga hiperactiva en pediatría es la oxibutinina; sin embargo, muchos pacientes responden parcialmente a esta terapia o son refractarios a la misma. La electroterapia vesical ha surgido como nueva alternativa en el algoritmo de manejo de los pacientes con vejiga hiperactiva refractaria a los fármacos anticolinérgicos, pero la evidencia bibliográfica al respecto hasta la fecha es escasa. Presentamos el caso de una paciente de 12 años con vejiga hiperactiva refractaria a oxibutinina y solifinacina que presentó una buena respuesta al tratamiento con electroterapia vesical sacra, con desaparición completa de los síntomas (incontinencia diurna y urgencia miccional), sin efectos adversos

Urinary incontinence is one of the principal reasons for visiting the urologist amongst paediatric patients, and an overactive bladder is the vesical dysfunction that most frequently provokes this. Currently the only medicine approved for managing an overactive bladder is oxybutynin; however, many patients respond partially to this therapy or are refractory to it. Vesical electrotherapy has emerged as a new alternative in the algorithm for managing patients with an overactive bladder refractory to anticholinergic medicines, but the evidence on this issue has to date been scant. We present the case of a 12-year-old patient with an overactive bladder refractory to oxybutynin and solifenacin who presented a good response to treatment with sacral vesical electrotherapy, with complete disappearance of the symptoms (diurnal incontinence and urgency of micturition) without adverse effects

Predictors of a positive oral food challenge to cow's milk in children sensitized to cow's milk

INTRODUCTION AND OBJECTIVES: The diagnosis of IgE-mediated cow's milk allergy (CMA) is often based on clinical history and on specific IgE levels and/or skin-prick tests (SPT), both of which are sensitive but not specific. The gold standard, oral food challenge (OFC), is expensive and time-consuming and involves a risk of severe allergic reactions. This study aimed to determine the value of specific IgEs, ratios of specific IgEs for cow's milk and its components to total IgE, and wheal size on SPT for predicting a positive OFC for CMA. MATERIAL AND METHODS: We retrospectively studied 72 patients [median age, four years; age range 0.75-15 years] sensitized to cow's milk who underwent OFCs to milk. predictive variables between patients with positive and negative OFCs were compared. Receiver operator characteristic (ROC) curves were uses to assess variables' discriminatory capacity and Youden's index to determine the best cut-offs for predicting CMA. RESULTS: The OFC was positive in 39 (54%) patients. Wheal size on SPT and all specific IgEs and specific-to-total IgE ratios were significantly different between patients with positive OFCs and those with negative OFCs (p < 0.001). The variable with the greatest area under the ROC curve was casein-specific IgE (0.98), followed by β-lactoglobulin-specific IgE (0.923), casein-specific-to-total-IgE ratio (0.919), and α-lactalbumin-specific IgE (0.908). Casein-specific IgE ≥ 0.95kU/L yielded 88.9% sensitivity and 90.9% specificity. CONCLUSIONS: In our center, casein-specific IgE > 0.95kU/L can obviate an OFC to cow's milk for the diagnosis of CMA in patients sensitized to cow's milk with a compatible history
