En 2015 se publicaron en Archivos Argentinos de Pediatría las "Nuevas recomendaciones frente a las actuales controversias en infección urinaria". Dado que en estos años surgieron evidencias con respecto al diagnóstico, la forma de estudio y el tratamiento de la infección urinaria, el Comité de Nefrología Pediátrica de la Sociedad Argentina de Pediatría decidió actualizar dichas recomendaciones. El objetivo principal es brindar al pediatra las herramientas para realizar un correcto diagnóstico, definir el tratamiento más adecuado, seleccionar a los pacientes que se beneficiarán con la profilaxis antibiótica y decidir cuáles serán los estudios de imágenes necesarios, para evitar intervenciones costosas e invasivas. En estas guías se incluyen, además, los lineamientos para el manejo de niños con infecciones urinarias asociadas a situaciones especiales como la disfunción vesicointestinal, el recién nacido, los portadores de vejiga neurogénica, los receptores de trasplante renal y las infecciones urinarias micóticas.
In 2015, the "New recommendations regarding the current controversies in urinary infection" were published in the Archivos Argentinos de Pediatría. Given the fact that in these past years, new evidence has emerged regarding the diagnosis and treatment of urinary infection, the Pediatric Nephrology Committee of Sociedad Argentina de Pediatría has decided to update these recommendations. The main goal is to provide the pediatrician with the necessary tools to make a correct diagnosis, define the most appropriate treatment, select the patients who will benefit from antibiotic prophylaxis, and decide which imaging studies will be necessary, avoiding costly and invasive interventions. These guidelines also include the management of children with urinary tract infections associated with special situations such as: bladder bowel dysfunction, the newborn, children with neurogenic bladder, kidney transplant patients and fungal urinary tract infections.

Resumen La infección del tracto urinario (ITU) es una de las infecciones bacterianas más frecuentes en la infancia. Un adecuado diagnóstico es esencial para poder realizar un tratamiento racional, eficiente y eficaz; sin embargo, existe gran heterogeneidad en los métodos diagnósticos, específicamente en el estudio de la susceptibilidad antimicrobiana. El objetivo de estas recomendaciones es entregar herramientas para uniformar los criterios diagnósticos, el estudio de susceptibilidad bacteriana in vitro y el tratamiento antimicrobiano de la ITU en la población pediátrica, con un enfoque de uso racional de los antimicrobianos. En esta primera parte, se presentan las recomendaciones en cuanto a cómo obtener una adecuada muestra de orina, el diagnóstico de laboratorio incluyendo puntos de corte -unidades formadoras de colonias/mL de orina-, además de consideraciones microbiológicas para el estudio de susceptibilidad y finalmente, el manejo de la ITU en pediatría. En la segunda parte se detalla el tratamiento antimicrobiano de sus complicaciones, el manejo de ITU en situaciones especiales y consideraciones farmacocinéticas y farmacodinámicas de los antimicrobianos a indicar en ITU.
Abstract The urinary tract infection (UTI) is one of the most common bacterial infections in childhood. An adequate diagnosis is essential to be able to carry out a rational, efficient and effective treatment, however, there great heterogeneity in diagnostic methods, specifically in the study of antimicrobial susceptibility. The aim of these recommendations is to provide tools to homogenize the diagnosis criteria, susceptibility study and antimicrobial treatment of urinary tract infection in the pediatric population, with a rational use of antibiotics approach. In the first part, the recommendations regarding diagnosis are presented, such as sampling and cut-off points, as well as microbiological considerations for susceptibility study and management of UTI in pediatrics. The second part details the management of complications, UTI in special situations, and pharmacokinetic and pharmacodynamic considerations of antimicrobials to be prescribed in UTI.

Las infecciones del tracto urinario (ITU) son una consulta ambulatoria frecuente, afectan mayormente a mujeres y han ido en aumento en todas las edades, especialmente en adultos mayores. A su vez, la resistencia antimicrobiana está aumento progresivamente en el tiempo y esquemas antibióticos tradicionales han perdido su utilidad clínica. En particular, el aumento de resistencia de E. coli, como principal uropatógeno, es una realidad presente en diversos países y un mayor desafío lo constituyen las ITU causadas por cepas de E. coli productoras de betalactamasas de espectro expandido. El presente artículo revisa los factores de riesgo asociados al aislamiento de cepas resistentes, los cuadros clínicos más frecuentes, y también el diagnóstico y manejo en la situación actual a nivel ambulatorio.
Urinary tract infections (UTI) are a frequent outpatient consultation, it affects mostly women, and is becoming more common in all ages, especially in the elderly. Concurrently, antimicrobial resistance is progressively increasing over time and traditional antibiotic regimens have lost their clinical efficacy. In particular, in many countries the increase in resistance of E. coli (the main uropathogen) is a reality, making UTIs caused by E. coli strains that produce expanded spectrum beta-lactamases the greater challenge. This article reviews the risk factors associated with the isolation of resistant strains, common clinical presentations, and also current diagnosis and management of outpatients.

Introducción: La infección de vías urinarias es recurrente en el embarazo y generadora de complicaciones. Objetivo: Presentar un plan de cuidados enfermero a una mujer con diagnóstico infección de vías urinarias y amenaza de aborto Métodos: Caso clínico de paciente admitida en unidad de Ginecología y Obstetricia del Hospital General de Teziutlán, Puebla, México, durante 2019. Siguiendo la lógica del proceso de enfermería, la valoración se fundamentó en los patrones funcionales de salud de Marjory Gordon. Fueron utilizadas las terminologías normalizadas de enfermería: Diagnósticos (NANDA.int). Resultados (NOC) e Intervenciones (NIC). Resultados: Se identificaron cuatro diagnósticos de enfermería: deterioro de la eliminación urinaria, gestión ineficaz de la propia salud, disposición para mejorar la nutrición y riesgo de alteración de la díada materno/fetal, este último diagnóstico principal. Además, un Resultado NOC (Conocimiento: Control de Infección), cuatro indicadores y la escala de nunca a siempre demostrado; cuatro Intervenciones NIC, con 19 actividades. La evaluación transitó desde 12 (puntuación inicial) a 19 (puntuación final), de 20 como puntuación diana. Conclusión: La integración de las taxonomías NANDA, NIC, NOC y los patrones funcionales de salud de Marjory Gordon permitió diseñar el plan de cuidado de la embarazada, fueron articulados diagnósticos, resultados e intervenciones de enfermería que favorecieron la relación enfermera-paciente-contexto sociocultural, para llevar el cuidado hasta una concepción sistémica que permita el seguimiento y control de la embarazada(AU)
Introduction: Urinary tract infection is recurrent in pregnancy and causes complications. Objective: To present a nursing care plan provided to a woman with a diagnosis of urinary tract infection and threatened miscarriage. Methods: Clinical case of a patient admitted to the gynecology and obstetrics unit of General Hospital of Teziutlán (Puebla, Mexico) during 2019. Following the logic of the nursing process, the assessment was based on Marjory Gordon's functional health patterns. The standard nursing terminologies were used: diagnostics (NANDA-I), outcomes (NOC) and interventions (NIC). Results: Four nursing diagnoses were identified: deterioration of urinary elimination, ineffective self-health management, willingness to improve nutrition, and risk for alterations in maternal-fetal dyad, the latter being the main diagnosis. In addition, a NOC outcome (knowledge: infection control), four indicators and the never-to-always scale upon demonstration, as well as four NIC interventions, with nineteen activities, were obtained. Evaluation ranged from twelve (initial score) to nineteen (final score), with twenty as target score. Conclusion: The integration of the NANDA, NIC and NOC taxonomies together with the Marjory Gordon's functional health patterns allowed the design of the pregnant woman's care plan, with an articulation between nursing diagnoses, outcomes and interventions, which favored the nurse-patient-sociocultural context relationship, up to considering care based on a systemic conception that allows monitoring and control of the pregnant woman(AU)

Objetivo: O presente estudo tem como objetivo avaliar o perfil de sensibilidade antimicrobiana do patógeno mais comum causador da infecção do trato urinário (ITU) de gestantes que foram internadas em um hospital de ensino do município de São Paulo em determinado período. Métodos: Estudo retrospectivo, transversal, quantitativo, realizado avaliando as uroculturas positivas e o perfil de sensibilidade antimicrobiana dos agentes mais comuns encontrados em ITUs das gestantes de hospital e maternidade-escola do município de São Paulo de janeiro de 2019 ateÌ janeiro de 2020. Resultados: A partir da análise de uroculturas positivas e antibiograma de 149 gestantes admitidas com quadro de infecção urinária no referido hospital no intervalo de tempo analisado, constatou-se que 83,89% dos casos apresentaram como patógeno a bacteÌria Escherichia coli. No âmbito da resistência bacteriana, percebeu-se que o maior índice foi encontrado no que tange a cefalotina (65%), ampicilina (58%) e ampicilina/sulbactam (45%). Ademais, a partir das análises individuais, 20 pacientes, ou seja, aproximadamente 13,42% apresentaram cepas sensíveis a todas as medicações apontadas, e as demais apresentaram resistência a, pelo menos, uma delas. Conclusão: A partir da premissa de eficácia desempenhada pelo protocolo de medicação empírica estabelecido pela instituição no tocante ao tratamento de infecção do trato urinário em gestantes, a cefalotina certamente não deveria compor o rol de drogas ofertadas às pacientes. Isso se dá, pois a sensibilidade apresentada pela Escherichia coli, patógeno que mais comumente está associado aos quadros de ITU do serviço, a essa droga eÌ muito baixa. Já a nitrofurantoína apresentou um satisfatório espectro de cobertura, sendo a resistência à droga inferior a 10%. Com isso, conclui-se que ela deve permanecer como droga inicial para as ITUs das gestantes que chegam a essa instituição.(AU)
Objective: The present study aims to evaluate the antimicrobial sensitivity profile of the most common pathogen that causes urinary tract infection (ITU) in pregnant women who were admitted to a Teaching Hospital in the city of São Paulo in a specific period. Methods: Retrospective, cross-sectional, quantitative study carried out evaluating positive urine cultures and the antimicrobial sensitivity profile of the most common agents found in ITU of pregnant women at Teaching Maternity hospital in the city of São Paulo from January 2019 to January 2020. Results: From the of positive urine culture and antibiogram of 149 pregnant women admitted with a urinary tract infection in the referred hospital in the analyzed period of time, it was found that 83.89% of the cases presented the bacterium Escherichia coli as a pathogen. In the scope of bacterial resistance, it was noticed that the highest index was found with respect to Cephalothin (65%), ampicillin (58%) and ampicillin/sulbactam (45%). Furthermore, from the individual analyzes, 20 patients, that is, approximately 13.42% had strains sensitive to all the medications indicated, with the others showing resistance to at least one of them. Conclusion: Based on the premise of efficacy performed by the empirical medication protocol established by the institution regarding the treatment of urinary tract infection in pregnant women, Cephalothin should certainly not be included in the list of drugs offered to patients. This happens because the sensitivity presented by Escherichia coli, the most commonly pathogen associated with the UTI pathogen of the service, to this drug is very low. Nitrofurantoin, on the other hand, presented a satisfactory coverage spectrum, with drug resistance below 10%. Thus, it is concluded that this should remain as an initial drug for ITUs of pregnant women who arrive at this institution.(AU)

Los porcentajes de especificidad para los antimicrobianos testados fueron: ciprofloxacina (97%), fosfomicina (94%), cotrimoxazol (84%), ampicilina (80%) y amoxicilina/ácido clavulánico (55%). Conclusión: El dispositivo KAR® puede ser una herramienta útil para el diagnóstico de ITU en pacientes ambulatorios, especialmente en áreas de bajo nivel socio-económico.
Abstract Background: Urinary tract infections (UTI) presents a high prevalence in the community setting. Rapid and accurate microbiological diagnosis is essential to ensure adequate and effective therapy. Aim: To evaluate a rapid antibiogram kit (KAR®) in point-of-care format for rapid detection of UTI and antibiotic susceptibility. Methods: The KAR® device has been designed and developed in collaboration with technical engineers and clinical microbiologists. Its evaluation has been carried out through a multicenter study in which three Spanish hospitals have participated. Thus, different in vivo tests have been implemented in order to determine device correlation with the reference microbiological techniques. Results: During the study period, a total of 400 urine samples from patients with suspected ITU were tested. The KAR® device provided fast results (mean positivity time of 7,8 ± 1,5 hours) with 97% sensitivity, 89% specificity and 87% agreement for the detection of significant bacteriuria. The percentages of specificity for the antibiotics tested were: ciprofloxacin (97%), fosfomycin (94%),cotrimoxazole (84%), ampicillin (80%) and amoxicillin/clavulanic acid (55%). Conclusion: The KAR® device could be a useful tool for diagnosing UTI in outpatients, especially in areas of low socio-economic level.

La Sociedad Argentina de Infectología y otras sociedades científicas han actualizado estas recomendaciones utilizando, además de información internacional, la de un estudio multicéntrico prospectivo sobre infecciones del tracto urinario del adulto realizado en Argentina durante 2016-2017. La bacteriuria asintomática debe ser tratada solo en embarazadas, a quienes también se las debe investigar sistemáticamente; los antibióticos de elección son nitrofurantoína, amoxicilina, amoxicilina-clavulánico, cefalexina y trimetoprima-sulfametoxazol. Ante procedimientos que impliquen lesión con sangrado del tracto urinario se recomienda solicitar urocultivo para pesquisar bacteriuria asintomática, y, si resultara positivo, administrar antimicrobianos según sensibilidad desde inmediatamente antes hasta 24 horas luego de la intervención. En mujeres, la cistitis puede ser tratada con nitrofurantoina, cefalexina, o fosfomicina y no se recomienda usar trimetoprima-sulfametoxazol o fluoroquinolonas; en pielonefritis puede emplearse ciprofloxacina, cefixima o cefalexina si el tratamiento es ambulatorio o ceftriaxona, cefazolina o amikacina si es hospitalario. En los hombres, las infecciones del tracto urinario se consideran siempre complicadas. Se recomienda tratamiento con nitrofurantoina o cefalexina por 7 días, o bien monodosis con fosfomicina. Para la pielonefritis en hombres se sugiere ciprofloxacina, ceftriaxona o cefixima si el tratamiento es ambulatorio y ceftriaxona o amikacina si es hospitalario. Se sugiere tratar las prostatitis bacterianas agudas con ceftriaxona o gentamicina. En cuanto a las prostatitis bacterianas crónicas, si bien su tratamiento de elección hasta hace poco fueron las fluoroquinolonas, la creciente resistencia y ciertas dudas sobre la seguridad de estas drogas obligan a considerar el uso de alternativas como fosfomicina.
The Argentine Society of Infectious Diseases and other scientific societies have updated these recommendations based on data on urinary tract infections in adults obtained from a prospective multicenter study conducted in Argentina during 2016-2017. Asymptomatic bacteriuria should be treated only in pregnant women, who should also be systematically investigated; the antibiotics of choice are nitrofurantoin, amoxicillin, clavulanic/amoxicillin, cephalexin and trimethoprim-sulfamethoxazole. In procedures involving injury to the urinary tract with bleeding, it is recommended to request urine culture and, in the presence of bacteriuria, antimicrobial treatment according to sensitivity should be prescribed from immediately before up to 24 hours after the intervention. In women, cystitis can be treated with nitrofurantoin, cephalexin or fosfomycin, while trimethoprim-sulfamethoxazole and fluoroquinolones are not recommended; pyelonephritis can be treated with ciprofloxacin, cefixime or cephalexin in ambulatory women or ceftriaxone, cefazolin or amikacin in those who are hospitalized. In men, urinary tract infections are always considered complicated; nitrofurantoin or cephalexin are recommended for 7 days, alternatively fosfomycin should be given in a single dose. In men, ciprofloxacin, ceftriaxone or cefixime are suggested for pyelonephritis on ambulatory treatment whereas ceftriaxone or amikacin are recommended for hospitalized patients. Acute bacterial prostatitis can be treated with ceftriaxone or gentamicin. Fluoroquinolones were the choice treatment for chronic bacterial prostatitis until recently; they are no longer recommended due to the increasing resistance and recent concerns regarding the safety of these drugs; alternative antibiotics such as fosfomycin are to be considered.

Resumen: La infección del tracto urinario (ITU) es una de las infecciones bacterianas mas frecuentes en la edad pediátrica, pero su diagnóstico y manejo se pueden ver complicados por lo inespecífico de sus sín tomas y signos de presentación, la dificultad en la interpretación de los exámenes, especialmente en niños mas pequeños, y por un pronóstico respecto a daño renal muchas veces incierto. En los últimos años, se ha evidenciado una modificación significativa en el enfoque diagnostico y terapéutico de esta patología, surgiendo la necesidad de actualizar las recomendaciones previas. El propósito de esta re vision es contribuir a reducir la variabilidad de la práctica clínica en el manejo de ITU en la población pediátrica, mejorando la detección y manejo de la patología estructural y otros factores de riesgo de daño renal, evitando acciones innecesarias en aquellos niños con bajo riesgo. En esta primera parte, se presentan las recomendaciones en cuanto a diagnóstico y manejo de la ITU en pediatría. En la segunda parte se detalla su estudio, prevención y seguimiento.
Abstract: Urinary tract infection (UTI) is one of the most frequent bacterial infection in pediatrics. However, its diagnosis and management can be complicated due to the nonspecific clinical presentation, the difficulty of exams interpretation, especially in younger children, and an uncertain prognosis regar ding renal damage. In recent years, significant worldwide change has come in treatment, diagnosis, and images studies, we have decided to update the current recommendations on UTI management published by the Pediatric Nephrology branch of Chilean Pediatrics Society in previous years. The purpose of these recommendations is to reduce the variability of clinical practice in management of UTI in our pediatric population, favoring diagnostic and therapeutic interventions in the most ap propriate way, improving detection and management of structural pathology and other risk factors of renal damage, avoiding unnecessary actions in children with low risk. This first part includes diag nosis and treatment recommendations of urinary tract infection in pediatric age. In the second part the study, prevention and monitoring of urinary tract in pediatric age is detailed.

Abstract Urinary tract infection is a serious public health issue that predominantly affects women. In men, it is more often associated with prostatic hyperplasia and bladder catheterization. Urogenital tuberculosis presents with nonspecific with nonspecific symptoms and the diagnosis can be made in the presence of sterile leukocyturia and recurrent infection with acid urine. Non-tuberculous mycobacteria or other non-tuberculosis mycobacteria are opportunistic pathogens that inhabit the soil, water or environment surfaces, and usually cause diseases in immunocompromised individuals. Mycobacterium abscessus is an agent that causes lung, skin and soft tissue hospital infections. Urinary tract infections by this pathogen are rare.
Resumo Infecção do trato urinário é um sério problema de saúde pública que acomete predominantemente as mulheres. Em homens, está mais relacionada com hiperplasia prostática e cateterismo vesical. A tuberculose urogenital cursa com sintomas inespecíficos e o diagnóstico pode ser aventado na presença de leucocitúria estéril, e infecção recorrente com urina ácida. Micobactérias não tuberculosas ou mycobacteria other than tuberculosis são patógenos oportunistas que habitam o solo, a água ou superfícies do meio ambiente, e geralmente causam doenças em imunodeprimidos. Mycobacterium abscessus é um agente que causa infecções nosocomiais, pulmonares, de pele e de tecidos moles. Infecção urinária decorrente desse patógeno é considerada rara.

INTRODUCCIÓN: La infección del tracto urinario es la colonización y multiplicación microbiana a lo largo de la vía urinaria, es causa frecuente de consulta pediátrica. Su presentación clínica puede ser inespecífica y representa un riesgo de lesión permanente renal mientras menor es la edad del pa-ciente. El objetivo de este estudio fue determinar la prevalencia de los factores de riesgo conocidos de Infección del tracto urinario en pacientes hospitalizados menores de 5 años y mayores a un mes. MATERIALES y MÉTODOS: Se realizó un estudio descriptivo transversal en 68 pacientes con diagnóstico de infección del tracto urinario (confirmado por urocultivo), en el departamento de Pediatría del Hospital Humanitario Pablo Jaramillo hospitalizados entre enero del 2014 a diciembre del 2015. Se midió la prevalencia de los factores de riesgo de Infección del tracto urinario. Los datos se recolec-taron en un formulario con información obtenida de las historias clínicas y analizadas en SPSS V 20. Se evaluaron las posibles asociaciones entre las variables con el Chi cuadrado. RESULTADOS: el 67.6 % de la población fue del sexo femenino y 32.4 % al grupo masculino. El grupo etario con mayor prevalencia de ITU fue el de menores de 12 meses (80.9 %), con predominio del sexo femenino en todos los grupos etarios. Entre los factores de riesgo estudiados, se encontró que el antecedente materno de infección urinaria representó el 13.3 %. El reflujo vesico-ureteral se presentó en el 7.2 % y la hidronefrosis en el 8.8%. La fimosis fue predominante en los menores de 12 meses (11.7% del total de la población de estudio). El uso prolongado del pañal correspondió al 36.7 %. El 5.9% de los pacientes con ITU presentaron estreñimiento asociado. CONCLUSIÓN: La ITU es una patología infecciosa frecuente en menores de cinco años, con diferente distribución por edades de acuerdo al sexo. El grupo etario más frecuentemente afectado son los menores de 12 meses de edad, con predominio del sexo femenino. El uso prolongado del pañal (ma-yor a 8 horas) se constituye como el factor de riesgo estudiado de mayor prevalencia, y se encontró asociación estadísticamente significativa entre este factor y la ITU.(au)
BACKGROUND: Urinary tract infection is the colonization and microbial replication along the urinary tract, it is a frequent cause for seeking medical attention. Its clinical presentation is often nonspecific and represents a risk of permanent kidney damage, which is higher as younger is the patient. The aim of this study was to determine the prevalence of known risk factors for urinary tract infection in hospita-lized patients under the age of 5 years and older than a month of age. METHODS: A descriptive cross-sectional study was carried out in 68 patients with diagnosis of urinary tract infection (confirmed by urine culture), hospitalized at the Pediatrics department of Hospital Humanitario Pablo Jaramillo from January 2014 to December 2015. We measured the prevalence of the known risk factors for urinary tract infection. Data was collected in a form with the information obtained from the medical records and analyzed in SPSS V 20. Possible associations between the variables was evaluated with the Chi square test. RESUlTS: 67.6% of the sample were women and 32.4% were men. The age group with the highest prevalence of UTI was the group under 12 months (80.9%), with a higher frequency in females in all age groups. Among the risk factors, the maternal background of urinary infection represented 13.3%. Vesico-ureteral reflux represented 7.2% and hydronephrosis 8.8%. Phimosis was predominant in children under 12 months (11.7% of the total sample). The prolonged use of the diaper corresponded to 36.7 %. 5.9% of the patients with UTI presented constipation. CONClUSION: UTIs are a frequent infectious disease in children under 5, with different distribution according to age and sex. The age group more frequently affected was the group under 12 months of age, and it was higher on women. Prolonged used of diaper (higher than 8 hours) was the most frequent risk factor in this study, and we found statistical significant association between this two variables.(au)

Introducción. El objetivo fue evaluar las características clínicas y la evolución del reflujo vesicoureteral (RVU) según el sexo y grado de RVU.Población y métodos. Se incluyeron pacientes con RVU vistos durante el seguimiento de rutina entre enero de 2014 y enero de 2015. Se registraron las características demográficas, la evolución, los laboratorios y las imágenes.Resultados. Se seleccionó a 220 pacientes, cuya media de edad del diagnóstico era 3,17 ± 3,08 años; en ese momento, los varones eran menores que las niñas (2,00 ± 2,59 vs. 3,81 ± 3,15, p < 0,001). La infección urinaria fue la presentación más frecuente, seguida de hidronefrosis prenatal (HNP). El 22 % de los pacientes tuvo reflujo de grado 1-2; el 51 %, de grado 3; y el 27 %, de grado 4-5. En el reflujo de grado 4-5, las ecografías y gammagrafías con ácido dimercaptosuccínico (DMSA) marcado con 99mTc presentaron más anomalías, y se realizaron más cirugías (p < 0,001). En los varones, fueron más comunes el reflujo de grado 4-5 (43,6 % vs. 18,3 %) y las anomalías ecográficas (77 % vs. 54 %) y en la DMSA (77 % vs. 59 %) (p < 0,05). En las niñas, hubo mayores tasas de infección urinaria, disfunción de las vías urinarias inferiores y resolución espontánea (p < 0,05).Conclusiones. A pesar de la menor edad al momento del diagnóstico, la resolución espontánea fue menor en los varones, y estos presentaron HNP, reflujo grave y anomalías radiológicas más frecuentemente.
Introduction. The aim of the study was to assess the clinical features and outcome parameters of children with vesicoureteral reflux (VUR) based on gender and VUR grade.Population and methods. Patients with VUR who were seen during routine follow-up visits at Ankara University Children's Hospital between January 2014-January 2015 were included in this retrospective study. Patient demographics, clinical course, laboratory investigations, imaging were noted.Results. Two hundred and twenty patients were recruited. Mean age at the time of diagnosis was 3,17 ± 3,08 years. Boys were diagnosed at younger ages as compared to girls (2.00 ± 2,59 vs. 3,81 ± 3.15, p < 0.001). Urinary tract infection (UTI) was the most common presentation. The second presentation form was antenatal hydronephrosis (AHN) which was more common in males (25.6 %, p < 0.001). Twenty-two percent of the patients had grade 1-2, 51 % grade 3 and 27 % grade 4-5 reflux. Patients with grade 4-5 reflux had more abnormal ultrasound (US) and Tech 99m dimercaptosuccinic acid scintigraphy (DMSA) findings and surgery was performed more frequently in this group (p < 0.001). In males, grade 4-5 reflux (43.6 % vs. 18.3 %), abnormal US (77 % vs. 54 %) and DMSA (77 % vs. 59 %) findings were more frequent (p < 0.05). In girls higher rates of UTIs, lower urinary tract dysfunction (LUTD) and spontaneous reflux resolution were seen (p < 0.05).Conclusions: Despite younger age at diagnosis, spontaneous resolution was found lower in boys and they had more frequent AHN, more severe reflux, and radiological abnormalities.

ABSTRACT Introduction Vesicoureteral Reflux (VUR) is characterized by a retrograde flow of urine from the bladder into the ureters and kidneys. It is one of the most common urinary tract anomalies and the major cause of urinary tract infection (UTI) in the first years of life. If not properly diagnosed and treated can lead to recurrent UTI, renal scar and, in severe cases, to end stage renal disease. Despite recent advances in scientific and technological knowledge, evaluation and treatment of VUR is still controversial and there is still considerable heterogeneity in evaluation methods and therapeutic approaches. The aim of the present consensus is to give a practical orientation on how to evaluate and treat VUR. Methods The board of Pediatric Urology of the Brazilian Society of Urology joined a group of experts and reviewed all important issues on Vesicoureteral Reflux evaluation and treatment and elaborated a draft of the document. On November 2017 the panel met to review, discuss and write a consensus document. Results and Discussion Vesicoureteral Reflux is a common and challenging problem in children. Children presenting with Vesicoureteral Reflux require careful evaluation and treatment to avoid future urinary tract infections and kidney scars. The panel addressed recommendations on up to date choice of diagnosis evaluation and therapies.

Resumen La melioidosis es una enfermedad infecciosa causada por Burkholderia pseudomallei cuyo diagnóstico clínico puede ser difícil debido a su variada presentación clínica y a las dificultades del diagnóstico microbiológico, por lo cual pueden requerirse técnicas moleculares para su adecuada identificación una vez se sospecha su presencia. Son pocos los antibióticos disponibles para el tratamiento de esta enfermedad y, además, deben usarse durante un tiempo prolongado. Aunque se conoce por ser endémica en Tailandia, Malasia, Singapur, Vietnam y Australia, en Colombia se han reportado algunos pocos casos. Se presenta un caso de melioidosis en la región norte de Colombia, se hace una revisión de las características clínicas y el tratamiento, y se describe la epidemiología local de esta enfermedad.
Abstract Melioidosis is an infectious disease caused by Burkholderia pseudomallei whose clinical diagnosis can be difficult due not only to its varied clinical presentation but also to the difficulties in the microbiological diagnosis.Thus, it may be necessary to use molecular techniques for its proper identification once it is suspected. There are few antibiotics available for the treatment of this disease, which must be used over a long period of time. Although it is known to be endemic in Thailand, Malaysia, Singapore, Vietnam, and Australia, in Colombia there are few reported cases. We describe a case of melioidosis in the northern region of Colombia. Additionally, we review its clinical characteristics and treatment and we describe the local epidemiology of this disease.

ABSTRACT Introduction: Urinary tract infection (UTI) is the most common serious bacterial infection in young infants. Signs and symptoms are often nonspecific. Objectives: To describe clinical, demographic and laboratory features of UTI in infants ≤ 3 months old. Methods: Cross-sectional study of infants ≤ 3 months old with UTI diagnosed in a pediatric emergency department, for the period 2010-2012. UTI was defined as ≥ 50,000 colony-forming units per milliliter of a single uropathogen isolated from bladder catheterization. Paired urinalysis and urine culture from group culture-positive and group culture-negative were used to determine the sensitivity and specificity of pyuria and nitrite tests in detecting UTI. Results: Of 519 urine cultures collected, UTI was diagnosed in 65 cases (prevalence: 12.5%); with male predominance (77%). The most common etiologies were Escherichia coli (56.9%), Klebsiella pneumoniae (18.5%) and Enterococcus faecalis (7.7%). Frequent clinical manifestations were fever (77.8%), irritability (41.4%) and vomiting (25.4%). The median temperature was 38.7°C. The sensitivity of the nitrite test was 30.8% (95%CI:19.9-43.4%), specificity of 100% (95%CI:99.2-100%). Pyuria ≥ 10,000/mL had a sensitivity of 87.7% (95%CI:77.2-94.5%), specificity of 74.9% (95%CI:70.6 -78.8%). The median peripheral white blood cell count was 13,150/mm3; C-reactive protein levels were normal in 30.5% of cases. Conclusions: The male: female ratio for urinary tract infection was 3.3:1. Non-Escherichia coli etiologies should be considered in empirical treatment. Fever was the main symptom. Positive nitrite is highly suggestive of UTI but has low sensitivity; whereas pyuria ≥ 10,000/mL revealed good sensitivity, but low specificity. Peripheral white blood cell count and C-reactive protein concentration have limited usefulness to suggest UTI.
RESUMO Introdução: A infecção do trato urinário (ITU) é um quadro infeccioso grave mais frequente em lactentes jovens, cujos sinais e sintomas são frequentemente inespecíficos. Objetivos: Descrever aspectos clínicos, demográficos e laboratoriais de ITU em lactentes ≤ 3 meses. Métodos: Estudo transversal de ITU diagnosticada em lactentes ≤ 3 meses, em pronto-socorro geral de pediatria, entre 01/01/2010 a 31/12/2012. Diagnóstico de ITU definida como crescimento ≥ 50.000 unidades formadoras de colônia por mililitro de uropatógeno único, colhido por cateterismo vesical. Urina tipo I e urocultura foram pareadas dos grupos cultura-positiva e cultura-negativa para determinar a sensibilidade e especificidade de piúria e teste do nitrito para o diagnóstico de ITU. Resultados: Das 519 uroculturas colhidas, confirmou-se 65 casos de ITU (prevalência: 12,5%), com predomínio em meninos (77%). As etiologias mais frequentes foram Escherichia coli (56,9%), Klebsiella pneumoniae (18,5%) e Enterococcus faecalis (7,7%). Os sintomas mais frequentes foram febre (77,8%), irritabilidade (41,4%) e vômitos (25,4%). A temperatura mediana foi de 38,7°C. A sensibilidade do nitrito positivo foi de 30,8% (IC95%:19,9-43,4%), especificidade de 100% (IC95%:99,2-100%). Piúria ≥ 10.000/mL apresentou sensibilidade de 87,7% (IC95%:77,2-94,5%), especificidade de 74,9% (IC95%:70,6-78,8%). A contagem mediana de leucócitos foi 13.150/mm3. A proteína C reativa foi normal em 30,5% dos casos. Conclusões: A proporção entre meninos e meninas para ITU foi de 3,3:1. Outros agentes além de Escherichia coli devem ser considerados no tratamento empírico. A febre foi a principal queixa. O nitrito positivo é altamente sugestivo de ITU mas tem baixa sensibilidade; enquanto que a piúria ≥ 10.000/mL revelou boa sensibilidade, porém baixa especificidade. Leucograma e proteína C reativa demonstraram pouca utilidade clínica para sugerir ITU.
