Absceso de Brodie en la clavícula: una forma poco frecuente de presentación / Brodie abscess in the clavicle: an uncommon presentation

La osteomielitis (OM) se define como la inflamación ósea de origen infeccioso. La forma aguda es frecuente en la edad pediátrica. El absceso de Brodie es un tipo de osteomielitis subaguda, históricamente con baja incidencia, pero que actualmente se presenta un aumento de la misma. De poca repercusión clínica, con pruebas de laboratorio inespecíficas y estudios radiológicos de difícil interpretación, es crucial la sospecha diagnóstica. Se asemeja a procesos neoplásicos, benignos o malignos. Recae en la experiencia del profesional realizar el diagnóstico adecuado. El tratamiento consiste en antibioticoterapia, tanto parenteral como por vía oral, y eventualmente drenaje quirúrgico. Presentamos una paciente sana que consultó por una tumoración en topografía de clavícula izquierda de 3 meses de evolución. Se realizó diagnóstico de absceso de Brodie, inició tratamiento y se obtuvo una buena respuesta. Resulta imprescindible tener un alto índice de sospecha de esta entidad para no someter al paciente a estudios, pruebas invasivas o tratamientos erróneos, y evitar secuelas a futuro.

Osteomyelitis is defined as an inflammation of the bone caused by infection. Acute osteomyelitis is common in pediatrics. A Brodie abscess is a type of subacute osteomyelitis, with a historically low incidence; however, its incidence is currently increasing. Given its little clinical impact, with non-specific laboratory tests and radiological studies of difficult interpretation, diagnostic suspicion is crucial. It resembles neoplasms, either benign or malignant. An adequate diagnosis falls on the health care provider's experience. Treatment consists of antibiotics, both parenteral and oral, with potential surgical drainage. Here we describe the case of a healthy female patient with a tumor found in the topography of the left clavicle 3 months before. She was diagnosed with Brodie abscess; treatment was started with a good response. A high index of suspicion of Brodie abscess is critical to avoid invasive tests and studies or inadequate treatments, and to prevent future sequelae.

Microbiología de la colecistitis aguda y selección de antibióticos basado en el perfil de sensibilidad / Microbiology of acute cholecystitis and antibiotic selection based on sensitivity profile

OBJETIVO: determinar la microbiología y la prevalencia de cultivos de bilis positivos en la Colecistitis Aguda (CA). METODOLOGÍA DE LA INVESTIGACIÓN: serie de casos consecutivos anidados en una cohorte RESULTADOS: se han incluido 196 pacientes con un promedio de edad de 46,5 años (DE± 14,735 años) distribuidos por género en 88 pacientes del género femenino (44,9%) y 108 del género masculino (55,1%). El promedio de leucocitosis fue de 10.000 x mm3 con desvío izquierdo (80% de segmentados promedio). La prevalencia de cultivos positivos durante la CA fue de 64 pacientes (32,65%). El germen más cultivado fue la E. Coli en 28 pacientes con (43,75 %). En la sensibilidad del antibiograma, amoxicilina y Acido clavulánico presenta 53,12% de resistencia cuando están asociadas y 25,56% cuando se usa amoxicilina sola. La amikacina, ceftriaxona, cefepime, imipemen, cloranfenicol, ciprofloxacina, cotrimoxazol y gentamicina tienen sensibilidad superior al 50%. En las formas edematosas el cultivo fue de 19,7%, hidrops vesicular 31,25%, en piocolecisto el porcentaje de cultivos positivos fue de 50% y en abscesos retrovesiculares fue de 79,16%. CONCLUSIONES: la prevalencia de cultivo positivo en CA es de 32,65% con la E. Coli como germen más frecuente. La elección del antibiótico debe estar basada en el conocimiento de la microbiología del Hospital y de la sensibilidad determinada por los cultivos y antibiograma

Manejo de la hipoxia durante ventilación unipulmonar en un paciente con absceso mediastinal y mediastinitis para toracotomía abierta. Reporte de caso / Hypoxia Management during One-Lung Ventilation in a Patient with Mediastinal Abscess and Mediastinitis for Open Thoracotomy. Case Report

Introducción: la mayoría de los pacientes que se someten a cirugía torácica pueden ser clasificados en el grupo de alto riesgo para hipoxia, especialmente cuando se decide por una ventilación unipulmonar, debido al desequilibrio V/Q; por lo tanto, se han desa-rrollado nuevas estrategias ventilatorias y maniobras de rescate para hipoxia. Curso clínico: presentamos una paciente de 85 años de edad sin comorbilidades programada para toracotomía abierta y manejada con ventilación unipulmonar. Durante el mane-jo anestésico, se presenta hipoxia secundaria a desequilibrio V/Q y choque hipovolémi-co hemorrágico, con respuesta positiva a las maniobras de rescate para hipoxia. Con-clusión: es importante prevenir en la medida de lo posible la hipoxia en la ventilación unipulmonar, siguiendo las nuevas estrategias ventilatorias. Sin embargo, cuando se presenta una crisis, no debemos retrasar las maniobras de rescate de forma moderna. (AU)

Introduction: most of the patients undergoing thoracic surgery fit in the high risk group for hypoxia, especially when deciding to use one-lung ventilation due to the V/Q mis-match; therefore, new ventilation strategies and hypoxia rescue manoeuvres have been developed. Clinical course: we present an 85-year old female with no major co-morbidities scheduled for open thoracotomy and managed with one-lung ventilation. During the course of the anaesthetic management, hypoxia presents secondary to V/Q mismatch and haemorrhagic hypovolemic shock, with a positive response to hypoxia rescue manoeuvres. Conclusion: it is important to prevent as much as we can the hy-poxia in a one-lung ventilation following the new ventilation strategies. Although when facing a crisis, proper hypoxia management with a modern approach should not be de-layed. (AU)

Absceso en miocardio secundario a neumonía adquirida en la comunidad por Pseudomona aeruginosa en lactante inmunocompetente: reporte de caso / Myocardial abscess secondary to community acquired Pseudomona aeruginosa pneumonia in an immunocompetent infant: case report

La Pseudomona aeruginosa es una causa importante de infecciones asociadas a la atención de la salud y en las neumonías adquiridas en la comunidad, rara vez se identifica como el agente patógeno, siendo estas de progresión rápida y de mal pronóstico. Se trata de un menor de un año de edad inmunocompetente el cual fallece en casa una semana después de una lesión en la planta del pie derecho que según familiares le sacaron "pus", tratado con antinflamatorios y analgésicos. Se le realizó necropsia que evidenció cicatriz en planta de pie derecho sin lesiones traumáticas. Pulmones de consistencia indurada, con adherencias y áreas que impresionan necróticas, asociada a efusión pleural. El estudio histológico reportó un proceso infeccioso pulmonar agudo abscedado que se diseminó por continuidad a tejido cardiaco y en estudios microbiológicos de pulmón y bazo se reportó Pseudomona aeruginosa.

Pseudomona aeruginosa is an important cause of health care-associated infections and in community-acquired pneumonias, it is rarely identified as the pathogenic agent, being of rapid progression and poor prognosis. This is a one-year-old immunocompetent minor who died at home one week after a lesion in the sole of the right foot which, according to family members, caused "pus", treated with anti-inflammatory and analgesic drugs. A necropsy was performed, which showed a scar on the sole of the right foot with no traumatic lesions. Lungs of indurated consistency, with adhesions and areas that appear necrotic, associated with pleural effusion. The histological study reported an abscessed acute pulmonary infectious process that spread by continuity to cardiac tissue and microbiological studies of lung and spleen reported Pseudomona aeruginosa.

Abscesos mamarios múltiples por Mycobacterium abscessus en mastopexia secundaria con implantes mamarios / Multiple breast abscesses due to Mycobacterium abscessus in secondary mastopexy with breast implant

Las infecciones periprotésicas son una complicación poco frecuente en cirugía de implantes mamarios, pero de difícil resolución si son causadas por gérmenes como las micobacterias. Mycobacterium abscessus es una micobacteria no tuberculosa de rápido crecimiento, que se presenta de manera atípica, generando abscesos y fístulas cutáneas. En este reporte presentamos el caso de una paciente que fue intervenida por recambio de implantes mamarios y mastopexia secundaria. La paciente presentó un seroma temprano como manifestación inicial y posteriormente desarrolló múltiples abscesos en todo el parénquima mamario. El tratamiento instaurado en la paciente fue la extracción del implante mamario,curaciones diarias de la herida, antibioticoterapia prolongada y punciones periódicas guiadas por ecografía, con cultivo del material obtenido. El objetivo de nuestro reporte fue presentar esta complicación generada por un germen poco frecuente, su forma de presentación, diagnóstico y el tratamiento establecido

Although periprosthetic infections are a rare complication in breast implant surgery, they are difficult to resolve if they entail germs like mycobacteria. Mycobacterium abscessus is a rapidly growing, nontuberculous mycobacterium that occurs atypically and generates abscesses and cutaneous fistulas. In this report, we present the case of a patient that underwent surgery for a breast implant replacement and a secondary mastopexy. The initial manifestation the patient evinced was an early seroma. Later, she developed multiple abscesses in all the breast parenchyma. The treatment established for the patient involved extracting the breast implant, daily cleaning and dressing of the wound, prolonged antibiotic therapy, and periodical punctures guided by ultrasound, accompanied by culture sampling. The aim of this report is to present this infrequent germ-generated complication, its form of manifestation, its diagnosis, and the established treatment.

Regional analgesia and surgical site infections after colorectal surgery: a retrospective cohort analysis

Abstract Background The effect of regional analgesia on perioperative infectious complications remains unknown. We therefore tested the hypothesis that a composite of serious infections after colorectal surgery is less common in patients with regional analgesia than in those given Intravenous Patient-Controlled Analgesia (IV-PCA) with opiates. Methods Patients undergoing elective colorectal surgery lasting one hour or more under general anesthesia at the Cleveland Clinic Main Campus between 2009 and 2015 were included in this retrospective analysis. Exposures were defined as regional postoperative analgesia with epidurals or Transversus Abdominis Plane blocks (TAP); or IV-PCA with opiates only. The outcome was defined as a composite of in-hospital serious infections, including intraabdominal abscess, pelvic abscess, deep or organ-space Surgical Site Infection (SSI), clostridium difficile, pneumonia, or sepsis. Logistic regression model adjusted for the imbalanced potential confounding factors among the subset of matched surgeries was used to report the odds ratios along with 95% confidence limits. The significance criterion was p < 0.05. Results A total of 7811 patients met inclusion and exclusion criteria of which we successfully matched 681 regional anesthesia patients to 2862 IV-PCA only patients based on propensity scores derived from potential confounding factors. There were 82 (12%) in-hospital postoperative serious infections in the regional analgesia group vs. 285 (10%) in IV-PCA patients. Regional analgesia was not significantly associated with serious infection (odds ratio: 1.14; 95% Confidence Interval 0.87‒1.49; p-value = 0.339) after adjusting for surgical duration and volume of intraoperative crystalloids. Conclusion Regional analgesia should not be selected as postoperative analgesic technique to reduce infections.

Diagnosis and management of orbital and cranial complications of pediatric acute rhinosinusitis / 中华耳鼻咽喉头颈外科杂志

Objective: To review the clinical characteristics, to illustrate diagnosis and management experience of orbital and cranial complications of pediatric acute rhinosinusitis. Methods: The clinical data of 24 children with orbital and cranial complications of acute rhinosinusitis who received endoscopic sinus surgery combined with drug treatment in Beijing Children's Hospital from January 2017 to December 2021 were retrospectively reviewed. There were 19 boys and 5 girls. The age varied from 13 to 159 months, with a median 47.5 months. The following diagnoses were obtained: 12 isolated subperiosteal orbital abscess, 2 associated with preseptal abscess, 2 associated with intraorbital abscess, 7 associated with optic neuritis, and 1 associated with septic cavernous sinus thrombosis. Clinical characteristics, organism isolated and outcomes were analyzed through descriptive methods. Results: All 24 patients presented with fever; 9 presented with nasal congestion and purulent discharge. The clinical manifestations of orbital infection included orbital edema, pain, proptosis and displacement of globe in all patients, while visual impairment was recognized in 7 children. Purulent drainage was cultured in 17 patients, among which 12 were positive. All patients underwent nasal endoscopic surgical interventions uneventfully, excluding one patient who required a second surgical procedure. Follow-up period ranged from 5 to 64 months. All patients resolved fully, with the exception of 2 children who got permanent blindness with visual loss preoperative. There was no recurrence or death. Conclusions: Orbital and cranial complications of pediatric acute rhinosinusitis could be severe with an occult onset. For patients with vison impairment, any signs of intracranial complications and a lack of response to conservative management, an urgent endoscopic intervention is needed.

Multi-disciplinary treatment of severe palatal radicular groove of maxillary lateral incisor: A case report and literature review / 中南大学学报(医学版)

Palatal radicular groove is a developmental malformation of maxillary incisors, lateral incisors in particular, which often causes periodontal destruction. This paper reports a case of combined periodontal-endodontic lesions induced by palatal radicular groove, which was initially misdiagnosed as a simple periapical cyst. After root canal therapy and periapical cyst curettage, the course of disease was prolonged, resulting in the absence of buccal and maxillary bone plates in the affected tooth area. After the etiology was determined, the affected tooth was extracted and guide bone tissue regeneration was performed at the same time, followed by implantation and restoration at the later stage, leading to clinical cure. The palatal radicular groove is highly occult, and the clinical symptoms are not typical. If the abscess of the maxillary lateral incisor occurs repeatedly, and the abscess of the maxillary lateral incisor has not been cured after periodontal and root canal treatment, cone-beam computed tomographic and periodontal flap surgery should be considered.

Reverse partial pulmonary resection: a new surgical approach for pediatric pulmonary cysts / 南方医科大学学报

OBJECTIVE@#To evaluate the safety and efficacy of reverse partial lung resection for treatment of pediatric pulmonary cysts combined with lung abscesses or thoracic abscess.@*METHODS@#We retrospectively analyzed the clinical data of children undergoing reverse partial lung resection for complex pulmonary cysts in our hospital between June, 2020 and June, 2021.During the surgery, the patients lay in a lateral position, and a 3-5 cm intercostal incision was made at the center of the lesion, through which the pleura was incised and the fluid or necrotic tissues were removed.The anesthesiologist was instructed to aspirate the sputum in the trachea to prevent entry of the necrotic tissues in the trachea.The cystic lung tissue was separated till reaching normal lung tissue on the hilar side.The proximal end of the striated tissue in the lesion was first double ligated with No.4 silk thread, the distal end was disconnected, and the proximal end was reinforced with continuous sutures with 4-0 Prolene thread.The compromised lung tissues were separated, and the thoracic cavity was thoroughly flushed followed by pulmonary inflation, air leakage management and incision suture.@*RESULTS@#Sixteen children aged from 3 day to 2 years underwent the surgery, including 3 with simple pulmonary cysts, 11 with pulmonary cysts combined with pulmonary or thoracic abscess, 1 with pulmonary cysts combined with tension pneumothorax and left upper lung bronchial defect, and 1 with pulmonary herpes combined with brain tissue heterotaxy.All the operations were completed smoothly, with a mean operation time of 129 min, an mean hospital stay of 11 days, and a mean drainage removal time of 7 days.All the children recovered well after the operation, and 11 of them had mild air leakage.None of the children had serious complications or residual lesions or experienced recurrence of infection after the operation.@*CONCLUSION@#Reverse partial lung resection is safe and less invasive for treatment of complex pediatric pulmonary cysts complicated by infections.

Clinical analysis of patients with oral and maxillofacial infections in oral emergency / 北京大学学报(医学版)

OBJECTIVE@#To analyze the composition, incidence and clinical characteristics of oral and maxillofacial infections in oral emergency.@*METHODS@#A retrospective study on patients with oral and maxillofacial infections who visited the Department of Oral Emergency in Peking University School and Hospital of Stomatology from January 2017 to December 2019 was conducted. General characteristics, such as disease composition, gender, age distribution and position of involved teeth were analyzed.@*RESULTS@#A total of 8 277 patients with oral and maxillofacial infections were finally collected, including 4 378 male patients (52.9%) and 3 899 female patients (47.1%), with gender ratio of 1.12:1. The common diseases were periodontal abscess (3 826 cases, 46.2%), alveolar abscess (3 537 cases, 42.7%), maxillofacial space infection (740 cases, 9.0%), sialadenitis (108 cases, 1.3%), furuncle & carbuncle (56 cases, 0.7%) and osteomyelitis (10 cases, 0.1%). Male patients were more easily affected by periodontal abscess, space infection and furuncle & carbuncle than female patients with the gender ratios 1.24:1, 1.26:1, 2.50:1 individually, while the incidence of alveolar abscess, sialadenitis, furuncle & carbuncle had no significant gender difference. Different diseases were prone to occur at different ages. The peak ages of alveolar abscess were 5-9 and 27-67 years, while the peak age of periodontal abscess was 30-64 years. Space infection tended to occur between 21-67 years. There were 7 363 patients with oral abscess (3 826 patients with periodontal abscess and 3 537 patients with alveolar abscess), accounting for 88.9% of all the patients with oral and maxillofacial infections, involving 7 999 teeth, including 717 deciduous teeth and 7 282 permanent teeth. Periodontal abscess usually occurred in permanent teeth, especially the molar teeth. Alveolar abscess may occur in both primary teeth and permanent teeth. In primary teeth, the most vulnerable sites were primary molar teeth and maxillary central incisors while in permanent teeth the most vulnerable sites were first molar teeth.@*CONCLUSION@#Understanding the incidence of oral and maxillofacial infection was conducive to the correct diagnosis and effective treatment of clinical diseases, as well as targeted education for patients of different ages and genders to prevent the occurrence of diseases.

Assessment of main complications of regional anesthesia recorded in an acute pain unit in a tertiary care university hospital: a retrospective cohort

Abstract Background Regional anesthesia has been increasingly used. Despite its low number of complications, they are associated with relevant morbidity. This study aims to evaluate the incidence of complications after neuraxial block and peripheral nerve block. Methods A retrospective cohort study was conducted, and data related to patients submitted to neuraxial block and peripheral nerve block at a tertiary university hospital from January 1, 2011 to December 31, 2017 were analyzed. Results From 10,838 patients referred to Acute Pain Unit, 1093(10.1%) had side effects or complications: 1039 (11.4%) submitted to neuraxial block and 54 (5.2%) to peripheral nerve block. The most common side effects after neuraxial block were sensory (48.5%) or motor deficits (11.8%), nausea or vomiting (17.5%) and pruritus (8.0%); The most common complications: 3 (0.03%) subcutaneous cell tissue hematoma, 3 (0.03%) epidural abscesses and 1 (0.01%) arachnoiditis. 204 of these patients presented sensory or motor deficits at hospital discharge and needed follow-up. Permanent peripheral nerve injury after neuraxial block had an incidence of 7.7:10,000 (0.08%). The most common side effects after peripheral nerve block were sensory deficits (52%) and 21 patients maintained follow-up due to symptoms persistence after hospital discharge. Conclusion Although we found similar incidences of side effects or even lower than those described, major complications after neuraxial block had a higher incidence, particularly epidural abscesses. Despite this, other serious complications, such as spinal hematoma and permanent peripheral nerve injury, are still rare.

El identificar la etiología permite determinar diagnóstico, pronóstico y tratamiento ideal.

Introduction: Periodontal abscesses are the third most frequent dental emergency (6%-14%). Objective: To describe different etiological factors of periodontal abscesses in three patients. Case description: The first case was a 52-year-old woman who sought treatment due to spontaneous bleeding. During the examination, she revealed bleeding on probing (BP), presence of periodontal pockets (PP), and calculi (C). Scaling and root planning (SRP) was performed as treatment, which was complemented with detoxification with tetracycline and postoperative pharmacological treatment. The second case was a 27-year-old man who came to the clinic due to gum enlargement and showed BP and PP. The lesion was treated and SRP was performed. Finally, the third patient was a 21-year-old male who sought a follow-up consultation. The clinical examination showed the presence of dental calculi and periodontal pockets in teeth 16 and 17. SRP complemented with detoxification with tetracycline and postoperative pharmacology were used as treatments. Conclusion: The etiology of the periodontal abscesses in the first and third cases was based on the lack of depth during root scaling and planning. The cause in the second case was effects of food. Identifying this etiology is useful to achieve proper diagnosis, prognosis and treatment of periodontal abscesses.

Infección por Staphylococcus lugdunensis: descripción de 44 casos / Staphylococcus lugdunensis infection: report of 44 cases

INTRODUCCIÓN: Staphylococcus lugdunensis, es un estafilococo coagulasa negativa (SCN) con características de virulencia y de sensibilidad antimicrobiana que lo hacen más parecido a Staphylococcus aureus que a otros SCN. OBJETIVOS: Conocer las características clínicomicrobiológicas de los aislados de S. lugdunensis identificados en nuestra institución. MATERIAL Y MÉTODOS: Se realizó un estudio retrospectivo de los aislados de S. lugdunensis entre los años 2017 y 2019 en el Servicio de Microbiología del Hospital Universitario San Jorge de Huesca (España). Se revisaron las historias clínicas correspondientes a los pacientes con aislamiento de S. lugdunensis, considerándose las siguientes variables: edad, sexo, tipo de muestra, servicio de procedencia y enfermedad de base. La identificación bacteriana se realizó con MALDI-TOF VITEK MS (BioMérieux, Francia). Así mismo, se estudió su patrón de susceptibilidad antimicrobiana in vitro mediante microdilución en placa. RESULTADOS: Se obtuvieron 44 aislados de S. lugdunensis: 12 procedían de heridas, 10 fueron abscesos, 8 úlceras, 7 orinas, 4 frotis cutáneos, 2 exudados óticos, y 1 exudado vaginal. En relación con la enfermedad de base destacaron cinco pacientes con procesos tumorales y diez con diabetes mellitus. En 17 pacientes existían antecedentes de cirugía o traumatismo reciente. La mayoría de las cepas fueron sensibles a los antimicrobianos estudiados. En 19 de ellas se observó producción de β-lactamasa, dos fueron resistentes a macrólidos y tres a clindamicina. Todas las cepas fueron sensibles a oxacilina, gentamicina y cotrimoxazol. CONCLUSIONES: Aunque S. lugdunensis mantiene una buena sensibilidad a la mayoría de los antimicrobianos, su tendencia a producir abscesos y que exprese factores de virulencia más parecido a S. aureus que a otros SCN, hace necesaria una correcta identificación en el laboratorio con el fin de que su incidencia no quede subestimada.

BACKGROUND: Staphylococcus lugdunensis is a coagulase-negative staphylococcus (CNS) with virulence and antibiotic sensitivity characteristics which makes it more similar to Staphylococcus aureus than other CNS. AIM: To know the microbiological and clinical characteristics of S. lugdunensis isolates identified from our health sector. METHODS: A retrospective study of S. lugdunensis isolates was carried out between 2017 and 2019 in the Microbiology Service of the San Jorge University Hospital in Huesca (Spain). The clinical records of patients with S. lugdunensis isolation were reviewed, considering the following factors: age, sex, sample type, service and underlying disease. Bacterial identification was performed using MALDI-TOF VITEK MS (BioMérieux, France). The pattern of antibiotic susceptibility was studied by means of plate microdilution. RESULTS: 44 isolates of S. lugdunensis were obtained: 12 corresponded to wounds, 10 were abscesses, 8 ulcers, 7 urine samples, 4 skin smears, 2 otic exudates, and 1 vaginal exudate. Regarding the underlying disease, five patients had a tumor processes and ten had diabetes mellitus. In 17 patients there was a history of recent surgery or trauma. Most of the strains were susceptible to the antibiotics studied. Production of beta-lactamase was observed in 19 of them, two were resistant to macrolides and three to clindamycin. None of the isolates were resistant to oxacillin, gentamicin or cotrimoxazole. CONCLUSIONS: Although S. lugdunensis maintains a good sensitivity to most antibiotics, its tendency to produce abscesses and that it expresses virulence factors more similar to S. aureus than to other CNS requires a correct identification in the laboratory so that its incidence is not underestimated.

Hallazgos Clínicos, Radiográficos e Imagenológicos que permiten determinar el éxito de la Revascularización Pulpar / Achados Clínicos, Radiográficos e de Imagem que permitem determinar o Sucesso da Revascularização Pulpar / Clinical, Radiographic and Imaging Findings that allow determining the Success of Pulp Revascularization

Introducción:La revascularización pulpar es la terapia de primera elección para tratar al diente permanente inmaduro afectado por necrosis pulpar con periodontitis o absceso apical. Las evidencias indican que esta técnica induce la reparación de los tejidos dañados o perdidos, dentro y en la periferia, del conducto radicular. Durante los controles postoperatorios, el clínico dispone, fundamentalmente, de los hallazgos clínicos, radiográficos o imagenológicos, para interpretar y evaluar los resultados obtenidos con la terapia. Objetivo: Identificar los hallazgos clínicos, radiográficos e imagenológicos que determinan el éxito de la revascularización pulpar. Materiales y métodos: El desarrollo de la presente revisión narrativa se llevó a cabo mediante una estrategia de búsqueda en la base electrónica de datos y la consulta directa de portales web especializados. Además, se realizó una pesquisa en búsqueda de artículos primarios citados indiferentemente del año de publicación. Resultados: Fueron seleccionadas 25 publicaciones por su aporte y relevancia, de forma tal, que la presente revisión pueda cumplir con su objetivo. Conclusiones: Desde el punto de vista clínico, tanto para el control de los signos y síntomas de la infección como para inducir la reparación periapical, resulta una terapia exitosa. Ha demostrado que puede engrosar las paredes radiculares y estrechar el foramen apical a expensas de la deposición de un tejido mineralizado. Sin embargo, el alargamiento radicular sigue siendo un resultado incierto. La respuesta positiva a las pruebas de sensibilidad sugiere la existencia de un tejido vital en el interior del conducto radicular.

Introdução: A revascularização pulpar é a terapia de primeira escolha para o tratamento de dentes permanentes imaturos acometidos por necrose pulpar com periodontite ou abscesso apical. Evidências indicam que esta técnica induz o reparo de tecido danificado ou ausente dentro e ao redor do canal radicular. Durante os controles pós-operatórios, o clínico tem basicamente os achados clínicos, radiográficos ou de imagem para interpretar e avaliar os resultados obtidos com a terapia. Objetivo: Identificar os achados clínicos, radiográficos e de imagem que determinam o sucesso da revascularização pulpar. Materiais e métodos: O desenvolvimento desta revisão narrativa foi realizado por meio de uma estratégia de busca na base de dados eletrônica e consulta direta de portais especializados. Além disso, foi realizada uma busca em busca de artigos primários citados independente do ano de publicação. Resultados: 25 publicações foram selecionadas por sua contribuição e relevância, para que esta revisão possa cumprir seu objetivo. Conclusões: Do ponto de vista clínico, tanto para controlar os sinais e sintomas da infecção quanto para induzir o reparo periapical, é uma terapia de sucesso. Foi demonstrado que pode engrossar as paredes radiculares e estreitar o forame apical às custas da deposição de tecido mineralizado. No entanto, o alongamento da raiz continua sendo um resultado incerto. Uma resposta positiva aos testes de sensibilidade sugere a existência de tecido vital dentro do canal radicular.

Introduction: Pulpal revascularization is the first-choice therapy to treat immature permanent teeth affected by pulpal necrosis with periodontitis or apical abscess. Evidence indicates that this technique induces repair of damaged or missing tissue within and around the root canal. During the postoperative controls, the clinician basically has the clinical, radiographic or imaging findings to interpret and evaluate the results obtained with the therapy. Objective: To identify the clinical, radiographic and imaging findings that determine the success of pulpal revascularization. Materials and methods: The development of this narrative review was carried out through a search strategy in the electronic database and direct consultation of specialized web portals. In addition, a search was carried out in search of primary articles cited regardless of the year of publication. Results: 25 publications were selected for their contribution and relevance, so that this review can fulfill its objective. Conclusions: From the clinical point of view, both to control the signs and symptoms of the infection and to induce periapical repair, it is a successful therapy. It has been shown that it can thicken the root walls and narrow the apical foramen at the expense of the deposition of mineralized tissue. However, root elongation remains an uncertain outcome. A positive response to sensitivity tests suggests the existence of vital tissue within the root canal.
