RESUMO

PURPOSE: This study aims to provide an exhaustive analysis of pediatric low-grade gliomas (pLGGs) in the cerebellar hemispheres, focusing on incidence, clinical characteristics, surgical outcomes, and prognosis. It seeks to enhance understanding and management of pLGGs in the pediatric population. METHODS: We conducted an observational, descriptive, retrospective, and cross-sectional study at a pediatric hospital, reviewing medical records of 30 patients with cerebellar hemispheric pLGGs treated from December 2014 to January 2023. Data collection included demographics, clinical presentation, imaging findings, surgical approach, postoperative complications, histopathological diagnosis, hydrocephalus management, and follow-up. Molecular markers and adjuvant therapies were also analyzed. RESULTS: The cohort predominantly presented with cerebellar symptoms, with 60% showing hydrocephalus at diagnosis. MRI with gadolinium was crucial for diagnosis. Surgical focus was on achieving gross total resection (GTR), accomplished in 70% of cases. Postsurgical hydrocephalus was less common, and cerebellar mutism was not reported. While a complete molecular analysis was not performed in all cases, available data suggest significant influence of molecular markers on prognosis and therapeutic options of pLGGs. CONCLUSIONS: This study highlights the unique clinical and molecular characteristics of cerebellar hemispheric pLGGs in children. The lower incidence of postoperative hydrocephalus and absence of cerebellar mutism are notable findings. Emphasizing a multidisciplinary approach, our findings contribute to a deeper understanding of pediatric pLGGs, underscoring the need for personalized treatment strategies and vigilant follow-up.

RESUMO

BACKGROUND: Radicular cyst is a lesion of odontogenic origin that arises from epithelial remains due to periapical periodontitis caused by inflammatory reactions generated at the apex of affected teeth with infected or necrotic pulps. The therapeutic management of radicular cysts is controversial. There is only one case report of enucleation of a radicular cyst managed with microsurgery and apicoectomy, but without the use of the guided tissue regeneration (GTR) technique in the same surgical procedure. The present clinical case describes the management of a radicular cyst with microsurgical approach, performance of an apicoectomy of the tooth associated with the entity, application of GTR technique, use of a resorbable membrane of type I bovine collagen, and bovine xenograft. CASE SUMMARY: A 68-year-old patient presented with a radicular cyst from an upper lateral incisor. The microsurgical management used was aimed at enucleating the chemical membrane, performing apicoectomy of the tooth along with careful and precise retrograde filling, and implementing GTR technique using a resorbable collagen membrane and bovine xenograft. The diagnosis of radicular cyst was confirmed using histopathological analysis. The patient underwent follow-up evaluations at 10 and 30 d postoperatively. At 4 months postoperative evaluation, she remained asymptomatic, and radiographs showed significant periapical healing with adequate bone formation. CONCLUSION: These results suggest that microsurgical management using the GTR technique with collagen membrane and xenograft, contributes to bone regeneration.

RESUMO

The study of central nervous system (CNS) tumors is a subject of great interest and such knowledge is of great importance in medical practice. The classifications of CNS neoplasms began in the mid-19th century, until the World Health Organization (WHO) published, in 1979, the first edition of a useful systematic review for the purpose of establishing a common language for all medical specialties. To date, 5 updated editions of neoplastic taxonomy have been published. The fifth edition, from 2021, consolidates the paradigm shift brought about by molecular advances, although the transition between morphological and molecular biological characterization is still in progress. In this article, the new modifications introduced in the different most frequent families of tumors in pediatrics are analyzed, emphasizing useful information for pediatricians in their daily practice and multidisciplinary consultations.


El estudio de los tumores del sistema nervioso central (SNC) resulta ser un tema de gran consideración y su conocimiento reviste una alta importancia en la práctica médica. Las clasificaciones de las neoplasias del SNC comenzaron a mediados del siglo XIX hasta que en 1979 la Organización Mundial de la Salud (OMS) publicó la primera edición de una sistemática útil con el objetivo de establecer un lenguaje común para todas las especialidades médicas. Al día de hoy, 5 ediciones actualizaron la taxonomía neoplásica. La quinta edición del año 2021 consolida el cambio de paradigma dado por los avances moleculares, si bien todavía la transición se encuentra en proceso entre la caracterización morfológica y la biológica molecular. En este artículo, se analizan las nuevas modificaciones incorporadas en las diferentes familias tumorales más frecuentes en pediatría haciendo hincapié en aquella información de utilidad para el médico pediatra en su práctica diaria y la consulta multidisciplinaria.

RESUMO

The abusive head trauma (AHT) is a form of child abuse and is a frequent entity all over de world. It is particularly unique among medical diagnoses because of the legal implications imposed by the diagnosis. Therefore, it has been the subject of much legal controversy over the decades. Knowledge of the clinical signs and imaging findings of abusive head trauma is vitally important for early diagnosis. An oriented anamnesis, as well as a complete physical examination and obtaining adequate images of the central nervous system, play a significant role in confirming the presumptive diagnosis. The interdisciplinary approach (pediatricians, neurosurgeons, neuroradiologists, social workers, and other specialists) is the key in the management of these patients. The purpose of this article is to familiarize the pediatric neurosurgeon with some of the more common medicolegal issues surrounding AHT as well as to discuss legal commitments and ethical obligations of the neurosurgeon in Argentina (South America) based on 2 clinical cases.

RESUMO

Introducción: Los tumores de tronco constituyen neoplasias frecuentes en pediatría. Durante las últimas décadas y con el avance de los métodos de estudios por imágenes fueron desarrolladas clasificaciones con implicancias diagnósticas y terapéuticas. Hoy en día la biopsia estereotáxica es un tema controversial especialmente en las lesiones difusas.El objetivo del presente artículo es realizar una actualización de las indicaciones de este tipo de procedimiento en pediatría analizando también perspectivas futuras. Desarrollo: En la actualidad las biopsias estereotáxicas en tumores de tronco tienen indicaciones precisas ante tumores sin indicación quirúrgica o en casos no quirúrgicos. En pacientes con lesiones atípicas definida por imagen, presentación clínica o edad fuera del rango habitual se torna necesario el diagnóstico por anatomía patológica. El avance del estudio oncológico por biología molecular despertó interés en los gliomas difusos de la protuberancia. Hoy en día es aceptada la realización de esta cirugía en caso de protocolos de investigación, aunque la misma no tenga relevancia en la evolución del paciente. La toma de tejido para determinar la aplicación de tratamientos blanco junto a técnicas que posibilitan la aplicación de fármacos por microcatéteres colocados directamente en la lesión son posibles futuras aplicaciones de la estereotaxia para este tipo de tumores. Conclusiones: Los tumores de tronco en pediatría, por ser una patología frecuente, requieren un capítulo especial. Los avances en la clasificación de estos junto con los nuevos métodos de estudio de biología molecular tornan necesario definir las indicaciones de biopsia estereotáxica en este tipo de lesiones pudiendo cambiar el paradigma en un futuro cercano.


Introduction: Brainstem tumors are frequent neoplasms in pediatrics. During the last decades and with the advancement of imaging methods, classifications with diagnostic and therapeutic implications were developed. Today the stereotaxic biopsy is a controversial topic especially in diffuse lesions. Objectives: To update the indications for this type of procedure in pediatrics, also analyzing future perspectives. Discussion: At the present, stereotaxic biopsies in brainstem tumors have precise indications for tumors without surgical indication or in non-surgical cases. In patients with atypical lesions defined by MRI, clinical presentation or age outside the usual range, diagnosis by pathological anatomy becomes necessary.Advances in molecular biology in oncology have sparked interest in diffuse gliomas of the pons. Nowadays, the performance of this surgery is accepted in the case of research protocols, although it has no relevance in the patient`s outcome.Taking tissue to determine the application of target treatments together with techniques that allow the application of drugs by microcatheters placed directly in the lesion are possible future applications of stereotaxy for this type of tumors. Conclusions: Brainstem tumors in pediatrics, as they are a frequent pathology, require a special chapter. Advances in the classification of these, together with new molecular biology study methods make it necessary to define the indications for stereotaxic biopsy for this type of lesion, which may change the paradigm in the future.

RESUMO

Craniosynostosis in Apert syndrome is routinely treated by wide frontal and bilateral supraorbital reshaping and posterior cranial decompression. Dynamic cranial vault expansion has proved to be useful in craniofacial surgery, and its use has extended to syndromic patients. Although a controversy remains between conventional osteotomy and application of the spring-mediated technique in surgical treatment of craniosynostosis, there have been several positive clinical reports on expansion techniques for nonsyndromic and syndromic craniosynostosis. Simultaneous fronto-orbital advancement and posterior cranial vault expansion have been applied successfully to 2 patients of Apert syndrome, without intraoperative complications or postoperative morbidity and improving final cranial shape.

RESUMO

Objetivo. Describir y analizar una serie de pacientes operados en nuestro servicio por diferentes patologías, en los cuales se utilizó pericardio de donante no vivo para la realización de la duroplastía, obtenido del Banco de Tejidos de nuestro Hospital. Material y método. Se realizó un análisis retrospectivo de las historias clínicas de 33 pacientes en los cuales se utilizó pericardio humano, operados entre los años 2006 y 2008. Resultados. La edad de los pacientes fue entre 1 mes y 19 años (promedio: 6,6 años). 17 masculinos, 16 femeninos. Las cirugías en las cuales se utilizó, por diferentes motivos, pericardio humano para el cierre de la duramadre fueron: 7 cirugías por tumores de fosa posterior, 6 por tumores supratentoriales, 5 por traumatismos encefalocraneanos, 3 por malformación de Arnold-Chiari, 3 por hematomas espontáneos, 2 por malformaciones arteriovenosas, 2 por lipomas lumbosacros, 2 por encefaloceles, 1 por cirugía de la epilepsia, 1 por tumor espinal, y 1 por tumor de tronco. Las complicaciones encontradas fueron: 2 pseudomeningoceles y 1 fístula de líquido cefalorraquídeo, las que se resolvieron sin necesidad de nueva intervención quirúrgica. No se presentaron infecciones de la herida quirúrgica ni rechazo del injerto. Follow up: 18,6 meses. Conclusión. Consideramos que este material se comporta en forma excelente como sustituto de la duramadre, presentando ventajas tales como: ser impermeable, fácil de suturar y manejar, proporcionando un sellado hermético, baja antigenicidad y no inducir reacciones a cuerpo extraño.


Objective. To describe and to analyze a series of patients operated in our service by different pathologies, in which we used pericardium of alive donor for dural closure, stored at 80°Cbelow cero in our hospital. Method. A retrospective analysis was designed to evaluate the medical records of 33 patients in which human pericardiumwere used, in a period of time between 2006 and 2008. Results. The age of the patients ranged from 1 month to 19years old (average age: 6.6). 17 were male and 16 female. The surgeries in which we used, by different reasons, human pericardium for dural closure were: 7 posterior fossa tumors, 6supratentorial tumors, 5 traumatic brain injury (intracranial hypertension), 3 Arnold-Chiari malformations, 3 spontaneous haematomas, 2 arterio-venous malformations, 2 lumbo-sacrallipomas, 2 encephaloceles, 1 surgery for epilepsy, 1 spinal cord tumor, and 1 brainstem tumor. The complications found were: 2 pseudomeningoceles and 1 CSF fistula. There were no systemicallergic reactions or local skin changes or infections. Follow up: 18.6 months.Conclusion. We considered that human pericardium is an excellent, effective and safe cranial and spinal dural substitute, presenting advantages such as: to be impermeable, easy tosuture and to handle, providing hermetic sealing, low antigenicidadand not to induce reactions to strange body.

Objective. To describe and analyze a series of pediatric patients who underwent surgery for craniocerebral gunshot wounds. Material and method. The study is a retrospective review of the clinical charts of patients with cranial gunshot injuries seen between 1987 and 2007. Results. In this period 40 patients were admitted and 38 were operated on always with general anesthesia. Mean age of the children was 7 years. Twenty eight patients were male and twelve female. Twelve children sustained transhemipheric injurieds, ten extradural injuries, 9 tangencial injuries, 5 bihemipheric injuries and 3 transventricular injuries. Mortality rate was 20% with a mean follow up of 36 months. Conclusion. We conclude that almost all cranial gunshot patients should initially receive aggressive surgical therapy with a previous CT scan.

RESUMO

Objective: To describe and analyze a series of pediatric patients who underwent surgery for intracranial metastasis at our department, specially considering the paucity of publications in the literature on the topic in this age group. Material and method: The study is a retrospective review of the clinical charts of patients with intracranial metastasis seen between 1988 and 2006. Inclusion and exclusion criteria were established for the different cases. Results: In this period, 1740 CNS tumors were operated on, of which 12 cases were intracranial metastasis (0.7). Mean age of the children was 11 years. Six patients were male and 6 female. Location of the primary tumor was: suprarenal in 4 case, in the bone in 2, and in the bladder, kidney, testicle, hypopharynx, facial bone, and thigh in 1 case each. Four patients had multiple metastasis: 10 located in the cerebral hemispheres, 2 in the skull bone, and 2 at the epidural level. All patients presented with symptoms due to the brain metastases. Total resection was achieved in 9 cases, subtotal resection in1, and partial resection in 2. Mortality rate was 50, with a mean follo-up of 23 months. Conclusion: The incidence rate of brain metastasis in children in much lower than the published incidence rates in adults. The location of the primary tumor and histology found were also different. We consider surgery, when possible, a good therapeutic option within the multimodal treatment of metastases.
