Patients With Spina Bifida Have Longer Length of Hospital Stay: Statewide Health Care Utilization in California From 1995 to 2017.

INTRODUCTION: Our goal was to better understand the health care utilization of patients with spina bifida (SB) by evaluating length of hospital stay (LOS) as well as identifying what characteristics within the SB population are contributing to shorter or longer LOS. METHODS: By querying the Department of Health Care Access and Information database of all encounters at California-licensed hospitals from January 1995 through December 2017, this study analyzed LOS as a measure of health care utilization. Patients with SB were identified using the International Classification of Diseases-9 and -10 coding system, and the data collected for both SB and control cohorts were compared using linear and logistic regression models. RESULTS: Patients with SB spent a mean LOS of 7.3 days compared to 4.7 days among the control cohort (P < .001). In multivariable analysis, SB was found to be an independent predictor of longer LOS. Within the SB encounters, increasing comorbidities and nonprivate insurance were associated with longer LOS, while being female and Hispanic were associated with a shorter LOS. CONCLUSIONS: SB is an independent predictor of longer LOS when compared to the control cohort. These findings highlight the importance of understanding the preventive health care access and needs of the vulnerable SB population to decrease hospital utilization rates.

The impact of a biocellulose-based repair of fetal open spina bifida on the need to untether the cord: is it time to unify techniques for prenatal repair?

ABSTRACT Objective: To report the need for cord untethering after prenatal repair of open spina bifida using a unique biocellulose-based technique performed at a later gestational age. Methods: An observational cohort study was conducted to determine the incidence of tethered cord syndrome. Between May 2013 and May 2022, we performed 172 procedures using the percutaneous fetoscopic approach in fetuses at 26-28 weeks of gestation. After placode dissection, a biocellulose patch was placed to cover the placode, a myofascial flap (when possible) was dissected, and the skin was closed. Owing to death or loss to follow-up, 23 cases were excluded. Cord tethering syndrome was defined as symptoms of medullary stretching, and the infants were evaluated and operated on by local neurosurgeons after an magnetic resonance imaging examination. Infants over 30-month had ambulation and neurodevelopment evaluations (PEDI scale). Results: Among 172 cases operated at a median gestational age of 26.7 weeks and delivered at 33.2 weeks, 149 cases were available for postnatal follow-up, and cord untethering was needed in 4.4% of cases (6/136; excluding 13 cases younger than 12 months). Cerebrospinal fluid diversion and bladder catheterization were needed in 38% and 36% of cases, respectively. Of the 78 cases evaluated at 30 months, 49% were ambulating independently, and 94% had normal social function. Conclusion: The biocellulose-based technique was associated with a low rate of cord tethering, wich may be attributed to the lack of the duramater suture during prenatal repair, the formation of a neoduramater and/or later gestational age of surgery.

Biocellulose patch technique for fetoscopic repair of open spina bifida in twin pregnancy.

OBJECTIVES: Twin pregnancy is currently an exclusion criterion for prenatal repair of open spina bifida (OSB). The main objective of this study was to report on our experience of treating twin pregnancies with OSB using the skin-over-biocellulose for antenatal fetoscopic repair (SAFER) technique. We also discuss reconsideration of the current exclusion criteria for fetal OSB repair. METHODS: Eight fetuses with OSB from seven twin pregnancies underwent successful prenatal repair. Six pregnancies were dichorionic diamniotic with only one twin affected, and one was monochorionic diamniotic with both twins affected. Percutaneous fetoscopy was performed under CO2 insufflation of the sac of the affected twin. Neurosurgical repair was performed using a biocellulose patch to protect the placode, with the skin sutured to hold the patch in place, with or without a myofascial flap. Neurodevelopment was assessed using the pediatric evaluation of disability inventory scale in babies older than 6 months of adjusted age, whereas the Alberta scale was used for babies younger than 6 months of adjusted age. RESULTS: All 14 fetuses were liveborn and none required additional repair. Gestational age at surgery ranged from 27.3 to 31.1 weeks, and gestational age at birth ranged from 31.6 to 36.0 weeks. Four out of eight affected twins developed sepsis, but had a good recovery. No sequela of prematurity was found in any of the unaffected twins. Short-term neurodevelopment was normal in all evaluated unaffected twins (5/5) and in all but one affected twins (7/8). In the affected group, only one baby required ventriculoperitoneal shunt placement. CONCLUSIONS: Prematurity is frequent after fetal surgery, and the risk is increased in twin pregnancy. Nevertheless, prenatal surgery using the SAFER technique is feasible, with low risk to both twins and their mother when performed by a highly experienced team. Long-term cognitive assessment of the unaffected twin is needed. © 2023 The Authors.

Introduction: Congenital musculoskeletal disorders often present hip malformations that affect gait and functional activities, therefore the importance of detecting them in a timely manner. Objective: To determine the presence of dysplasia and hip dislocation in children with congenital disorders who attend a national rehabilitation institute. Material and Methods: An observational, descriptive, retrospective and cross-sectional study was conducted using 150 medical records of children from 0 to 2 years of age with congenital disorders with musculoskeletal involvement. Results: The patients had a median age of 11 months and 64 percen were female. The most frequent alteration was congenital deformity of the hip (52 percent), followed by spina bifida, congenital deformity of the ECOM, multiple arthrogryposis, and congenital deformity of the feet (23.3 percen, 6.7 percen, 5.3 percen and 4 percen, respectively). In addition, 17.3 percen of patients with congenital abnormalities had dislocation, 56.7 percen had dysplasia and 72.7 percen had either of the two. In patients with congenital hip deformity, 100% had dysplasia and/or dislocation. In patients with spina bifida, 54.3 percen had at least one of them. Moreover, 75 percen of patients with arthrogryposis multiplex and 33.3 percen of those with congenital deformities of the feet presented dysplasia and/or dislocation. Conclusions: Dysplasia and/or dislocation of the hip are common in children with a diagnosis of congenital hip deformity, spina bifida, congenital arthrogryposis multiplex, and congenital foot deformities(AU)

Postnatal Surgical Correction of Myelomeningoceles: Preoperative and Intraoperative Risk Factors Associated with Postoperative Neurologic Outcomes.

OBJECTIVE: Open spina bifida or myelomeningocele (MMC) is a congenital defect that results from failure of caudal neurulation. We present a case series of patients who were treated with postnatal surgical correction for MMC, evaluating the possible preoperative and intraoperative risk factors associated with neurologic outcomes. METHODS: A retrospective chart review of patients who underwent postnatal surgical correction for MMCs over 11 years at our institution was performed. MMCs were classified based on their morphologic configuration into 3 types. Type I includes defects without a sac and there is cerebrospinal fluid (CSF) leak. Type II includes where there is a sac ≤4 cm, with or without CSF leak. Type III includes defects with a sac that are greater than 4 cm. RESULTS: Fifty patients were included. The median age of gestation at surgery was 37.4 weeks. There were 30 females (60%). All mothers received adequate folate supplementation. All patients underwent surgical correction in the first 48 hours. Lower extremity motor function at the last clinical follow-up was normal in 34 patients (68%). CSF leak, infection, and mortality were 8%, 2%, and 0%, respectively. Twenty-one patients (42%) underwent ventriculoperitoneal shunt for hydrocephalus. CONCLUSIONS: Despite there being no statistically significant associations with a timely closure, all cases were treated within the first 48 hours and this could influence the low complication rate. Individuals of Hispanic background who received appropriate folate supplementation still had high rates of MMC and we posit that this may be caused in part by a genetic/molecular predisposition.

The Association of Health Literacy with Health-Related Quality of Life in Youth and Young Adults with Spina Bifida: A Cross-Sectional Study.

OBJECTIVE: The objective of the study was to determine if health literacy is associated with health-related quality of life (HRQOL) in adolescents and young adults (AYAs) with spina bifida. STUDY DESIGN: Between June 2019 and March 2020, the Patient-Reported Outcome Measurement Information System Pediatric Global Health-7 (PGH-7), a measure of HRQOL, and the Brief Health Literacy Screening Tool (BRIEF) were administered to patients ≥12 years old with a diagnosis of spina bifida seen in our multidisciplinary spina bifida center. Questionnaires were completed at scheduled clinic visits. The primary outcome was the PGH-7 normalized T-score. The primary exposure was the BRIEF score. Demographic and clinical characteristics were obtained from the medical record. Nested, multivariable linear regression models assessed the association between health literacy and the PGH-7 score. RESULTS: Of 232 eligible patients who presented to clinic, 226 (97.4%) met inclusion criteria for this study. The median age was 17.0 years (range: 12-31). Most individuals were female (54.0%) and had myelomeningocele (61.5%). Inadequate, marginal, and adequate health literacy levels were reported by 35.0%, 28.3%, and 36.7% of individuals. In univariable analysis, higher health literacy levels were associated with higher PGH-7 scores. In nested, sequentially adjusted multivariable linear regression models, a higher health literacy level was associated with a stepwise increase in the PGH-7 score. In the fully adjusted model, adequate health literacy and marginal health literacy, compared with inadequate health literacy, were associated with increases in a PGH-7 score of 3.3 (95% CI: 0.2-6.3) and 1.1 (95% CI: -2.0 to 4.2), respectively. CONCLUSIONS: Health literacy was associated with HRQOL after adjusting for demographic and clinical factors. Strategies incorporating health literacy are needed to improve HRQOL in AYAs with spina bifida.

Is there a role in the central nervous system development for using corticosteroids to treat meningomyelocele and hydrocephalus?

INTRODUCTION: Myelomeningocele (MMC) is the most frequent neural tube defect and is frequently associated (around 80% of cases) with hydrocephalus (HC). Both diseases can have severe clinical consequences, insomuch as they require surgical treatment whose complications are not negligible, either when performed in utero or after birth. Therefore, clinical therapies that could have an impact on the incidence and progression of MMC and HC would be certainly valuable; however, this is not the current picture, and there are no effective pharmacological treatments for such patients to this day. AIM AND METHODS: Therefore, knowing that an inflammatory process comes associated with these disorders, mostly due to nervous tissue distension, the present article aimed at reviewing the role of corticosteroids in reducing inflammation and thus improving the outcome of patients with HC and MMC, considering the well-established anti-inflammatory effects of CS. RESULTS: The systematic review performed herein has found varying results regarding the role of steroids (even though a positive trend was observed) on the treatment and prevention of hydrocephalus, whereas for MMC. CONCLUSION: There are many reports demonstrating beneficial effects of CS therapy, from a clinical and histopathological point of view.

Diagnóstico, manejo y tratamiento actual del mielomeningocele fetal / Current diagnosis, management and treatment of fetal myelomeningocele

Introducción: El mielomeningocele fetal, es la extrusión de la médula espinal que ocurre por un cierre incompleto del neuróporo caudal, lo cual expone la placa neural al trauma mecáni-co y químico de la pared uterina y líquido amniótico respectivamente, con graves secuelas. La detección prenatal innovó el diagnóstico y con ello la reparación intra útero ha mejora-do estrategias del tratamiento, generando opciones de atención en aquellas pacientes que cumplen con los criterios de selección para cirugía prenatal. Objetivo: Presentar una revisión bibliográfica sobre diagnóstico, manejo y tratamiento del mielomeningocele fetal y ofrecer a la comunidad científica una herramienta de consulta para mejorar los conocimientos del tema y alternativas de tratamiento oportuno para los fetos con esta malformación.Material y Métodos: Se trata de un estudio de revisión sistemática sin metaanálisis, realiza-do en base a las recomendaciones PRISMA. La búsqueda de información se estructuró bajo el sistema PICO. Las búsquedas se realizaron en Pubmed, Tripdatabase y Pubmed Central; seleccionando artículos publicados durante los últimos diez años en inglés o español, sobre diagnóstico, manejo y tratamiento del mielomeningocele fetal. Resultados: 120 artículos cumplieron con criterios de búsqueda, de los cuáles fueron ele-gibles 42, con información relevante para determinar el diagnóstico, manejo y tratamiento actual del mielomeningocele fetal a través de procedimientos innovadores.Discusión: Los defectos del tubo neural aparecen como consecuencia de una alteración del proceso de neurulación entre el día 21-28 después de la concepción. El mielomeningocele fetal es considerado el defecto congénito no letal más común del SNC. Se caracteriza por la protrusión de las meninges y la médula espinal con daño neurológico permanente. Por ello el diagnóstico y manejo oportuno de esta patología, han permitido que la cirugía fetal intra útero se considere el método óptimo, mejorando la hernia del rombencéfalo, reduciendo la necesidad de una derivación ventricular y manteniendo la motricidad inferior, así como la función neuronal, vesical y gastrointestinal, mejorando la calidad de vida del paciente afecto por esta patología

Introduction: Fetal myelomeningocele is spinal cord extrusion that occurs due to the caudal neuropore incomplete closure, which exposes the neural plate to mechanical and chemical trauma to the uterus wall and amniotic fluid respectively, with serious sequelae. Prenatal detection innovated the diagnosis and with this intra-uterine repair has improved treatment strategies, generating care options in those patients who comply the selection criteria for prenatal surgery.Objective: Submit a bibliographic review on the diagnosis, management and treatment of fetal myelomeningocele and to offer the scientific community a consultation tool to improve knowledge of the subject and timely treatment alternatives for fetuses with this malformation.Materials and Methods: This is a systematic review study without meta-analysis, based on the PRISMA recommendations. The information search was structured under the PICO sys-tem. The searches were carried out in Pubmed, Tripdatabase and Pubmed Central; selecting articles published during the last ten years in English or Spanish, on diagnosis, management and treatment of fetal myelomeningocele.Results: 120 articles met the search criteria, of which 42 were eligible, with relevant informa-tion for determining the current diagnosis, management and treatment of fetal myelomenin-gocele through innovative procedures.Discussion: Neural tube defects appear as a consequence of an alteration of the neurula-tion process between days 21-28 after conception. MMCf is considered the most common non-fatal congenital defect of the CNS. It is characterized by protrusion of the meninges and spinal cord with permanent neurological damage. For this reason, the diagnosis and timely management of this pathology have allowed intra utero fetal surgery to be considered the optimal method, improving rhombencephalon hernia, reducing the need for a ventricular shunt and maintaining the lower motor skills, as well as neuronal, bladder and gastrointestinal function, improving the quality of life of the patient affected by this pathology.

Lipomielomeningocele y médula anclada en un neonato: a propósito de un hallazgo cutáneo / Lipomyelomeningocele and tethered cord in neonate: a cutaneous finding / Lipomielomeningocele e medula ancorada em rescem nacido: um achado cutâneo

Introducción: el disrafismo espinal oculto comprende las anomalías congénitas caracterizadas por la fusión incompleta del tubo neural, en las que la lesión se encuentra cubierta por piel sin observarse exposición del tejido nervioso. Existen estigmas cutáneos que se asocian a su presencia, siendo los lipomas congénitos en la línea media posterior altamente sugerentes de lesión espinal. Su principal complicación es la asociación con el síndrome de médula anclada, que puede causar un daño neurológico irreversible. Caso clínico: recién nacida de sexo femenino, durante la exploración en Maternidad detectamos un estigma cutáneo del tipo lipoma en la región sacra sospechoso de disrafismo espinal oculto, confirmándose posteriormente, mediante estudio con ecografía y resonancia magnética, la presencia de lipomielomeningocele y médula anclada. Conclusiones: el reconocimiento de los marcadores cutáneos, que constituyen a veces la única manifestación de la enfermedad en pacientes asintomáticos, posibilitaría un diagnóstico precoz y manejo individualizado con posible corrección quirúrgica según el caso, que podría prevenir el daño neurológico irreversible asociado a la médula anclada.

Introduction: hidden spinal dysraphism involves congenital anomalies characterized by an incomplete fusion of the neural tube, where the lesion is covered by skin and the nervous tissue is not exposed. Some skin stigmas are linked with this spinal injury, mainly congenital lipomas in the posterior midline of the lesion. Hidden spinal dysraphism's main complication could be tethered cord syndrome, which can cause irreversible neurological damage. Clinical case: female newborn showing a lipoma-like skin stigma in the sacral region, looking like hidden spinal dysraphism, which was later confirmed through ultrasound and magnetic resonance imaging, which showed lipomyelomeningocele and a tethered cord. Conclusions: early detection of these skin markers is sometimes the only tool to early diagnosis and personalized treatment in asymptomatic patients. It enables a possible surgical remediation and may prevent the irreversible neurological damage linked to the tethered cord.

Introdução: o disrafismo espinhal oculto envolve anomalias congênitas caracterizadas por uma fusão incompleta do tubo neural, onde a lesão é coberta por pele e o tecido nervoso não fica exposto. Alguns estigmas de pele estão relacionados a essa lesão espinhal, principalmente lipomas congênitos na linha média posterior da lesão. A principal complicação do disrafismo espinhal oculto pode ser a síndrome da medula ancorada, a qual pode causar danos neurológicos irreversíveis. Caso clínico: recém-nascida apresenta estigma cutâneo semelhante a lipoma na região sacral, semelhante a disrafismo espinhal oculto, posteriormente confirmado por ultrassonografia e ressonância magnética, o que evidenciou lipomielomeningocele e medula ancorada. Conclusões: a detecção precoce desses marcadores cutâneos às vezes é a única ferramenta para o diagnóstico precoce e tratamento personalizado em pacientes assintomáticos. Permite uma possível correção cirúrgica e pode prevenir os danos neurológicos irreversíveis ligados à medula ancorada.

[Craniorachischisis: a case report]. / Craneorraquisquisis: reporte de un caso.

Background: Neural tube defects are a heterogeneous group of alterations of the central nervous system with multifactorial origin, mainly caused by a failure in the mechanisms of closure of the neural tube which involves skin, paravertebral muscles, connective tissue, bone and spinal cord. Clinical case: 36-year-old woman with a pregnancy of 25.3 weeks, corroborated by second trimester ultrasound. She had a previous pregnancy with anencephaly and a poor prenatal care in the actual pregnancy. An obstetric ultrasound was performed with the diagnosis of craniorachischisis, which is why the delivery was performed by vaginal birth with labor induction with prostaglandins. Conclusions: The craniorachischisis is a rare defect of the neural tube that must be diagnosed early because it is a pathology incompatible with life.

Introducción: los defectos del tubo neural son un grupo heterogéneo de alteraciones del sistema nervioso central, de origen multifactorial, principalmente ocasionados por una falla en los mecanismos de cierre del tubo neural, la cual involucra: piel, músculos paravertebrales, tejido conectivo, hueso y médula espinal. La craneorraquisquisis es la variante más grave y rara de los defectos del tubo neural. Caso clínico: Mujer de 36 años con un embarazo de 25.3 semanas, corroborado por ultrasonido del segundo trimestre, con el antecedente de un embarazo previo con anencefalia y mal control prenatal en el embarazo actual. Se le realizó un ultrasonido que diagnosticó craneorraquisquisis, por lo que se procedió a finalizar el embarazo por inducción de trabajo de aborto con prostaglandinas. Conclusiones: la craneorraquisquisis es un defecto raro del tubo neural que debe diagnosticarse tempranamente por ser una patología incompatible con la vida.

Historical Clinical Outcomes of Children with Myelomeningocele Meeting the Criteria for Fetal Surgery: A Retrospective Cohort Survey of Brazilian Patients / Resultados clínicos históricos de crianças com mielomeningocele com critérios para cirurgia fetal: Um estudo de coorte retrospectivo de pacientes brasileiros

Abstract Objective To analyze the historical clinical outcomes of children with myelomeningocele (MMC) meeting the criteria for fetal surgery, but who underwent postnatal primary repair. Methods Data from children undergoing postnatal MMC repair between January 1995 and January 2015 were collected from the Neurosurgery Outpatient Clinic's medical records. Children were included if they had ≥1 year of postoperative follow-up andmet the criteria for fetal surgery. The children's data were then stratified according to whether they received a shunt or not. The primary outcome was mortality, and secondary outcomes were educational delays, hospitalization, recurrent urinary tract infections (UTIs), and renal failure. Results Over the 20-year period, 231 children with MMC were followed up. Based on clinical data recorded at the time of birth, 165 (71.4%) qualify of fetal surgery. Of the 165 patients, 136 (82.4%) underwent shunt placement. The mortality rate was 5.1% in the group with shunt and 0% in the group without, relative risk (RR) 3.28 (95% confidence interval, 95% CI, 0.19-55.9). The statistically significant RRs for adverse outcomes in the shunted group were 1.86 (95% CI, 1.01-3.44) for UTI, 30 (95% CI, 1.01-537) for renal failure, and 1.77 (95% CI, 1.09-2.87) for hospitalizations. Conclusion Children with MMC qualifying for fetal surgery who underwent shunt placement were more likely to have recurrent UTIs, develop renal failure, and be hospitalized. Since approximately half of the shunt procedures could be avoided by fetal surgery, there is a clinical benefit and a possible financial benefit to the implementation of this technology in our setting.

Resumo Objetivo Analisar os resultados clínicos históricos de crianças commielomeningocele (MMC) com critérios para cirurgia fetal,mas que foram submetidas a cirurgia pós-natal. Métodos Dados de crianças submetidas à correção deMMCpós-natal entre janeiro de 1995 e janeiro de 2015 foram coletados nos prontuários do Ambulatório de Neurocirurgia. Foram incluídas crianças se tivessem ≥ 1 ano de acompanhamento pósoperatório e atendessem os critérios para cirurgia fetal. As informações dessas crianças foram então estratificadas de acordo com se receberam ou não derivação do líquido cefalorraquidiano. O desfecho primário foi a mortalidade e os desfechos secundários foram atrasos educacionais, hospitalização, infecções recorrentes do trato urinário einsuficiência renal. Resultados Durante o período de 20 anos, 231 crianças com MMC foram acompanhadas. Com base nos dados clínicos registrados no momento do nascimento, 165 (71,4%) atendiam critérios para a cirurgia fetal. Dos 165 pacientes, 136 (82,4%) foram submetidos à colocação de derivação do líquido cefalorraquidiano. A taxa de mortalidade foi de 5,1% no grupo com derivação do líquido cefalorraquidiano e 0% no grupo sem risco relativo (RR) 3,28 (intervalo de confiança 95%, IC 95%, 0,19-55,9). Os RRs estatisticamente significativos para resultados adversos no grupo com derivação do líquido cefalorraquidiano foram 1,86 (IC 95%, 1,01-3,44) para infecção do trato urinário, 30 (IC 95%, 1,01-537) para insuficiência renal e 1,77 (IC 95%, 1,09-2,87) para hospitalizações. Conclusão Crianças com MMC com critérios para cirurgia fetal submetidas à colocação de derivação do líquido cefalorraquidiano eram mais propensas a ter infecções recorrentes do trato urinário, desenvolver insuficiência renal e serem hospitalizadas. Como aproximadamente metade dos procedimentos de derivação poderiam ser evitados por cirurgia fetal, há um benefício clínico e um possível benefício financeiro com a implementação dessa tecnologia em nosso meio.

Validity of the VO2peak prediction model to Brazilian youth with spina bifida / Validação de um modelo preditivo do VO2pico em jovens brasileiros com espinha bífida

Objective:To validate a peak oxygen uptake (VO2peak) prediction model in Brazilian youth with spina bifida. Methods:Twenty participants with spina bifida performed a graded arm crank test to measure VO2peak. The VO2peakvalues predicted by the equation "VO2peak(mL/min) = 194 + 18 × peak workload ­110 × sex" were compared to the VO2peakvalues measured. Results:The predicted VO2peakwas not different from the measured VO2peak. A high correlation was found between both VO2peak values, and the Bland-Altman analysis did not show a significant difference, demonstrating agreement between the values. Conclusions:The VO2peak prediction model in Brazilian youth with spina bifida was validated, being an advantageous alternative to assess and follow physical fitness and prescribe exercise training intensity.

Objetivo: Validar uma equação preditiva do consumo pico de oxigênio (VO2pico) em jovens brasileiros com espinha bífida. Métodos: Vinte participantes com espinha bífida realizaram um teste ergoespirométrico de membros superiores para medir o VO2pico. Os valores de VO2pico preditos pela equação "VO2pico (mL/min) = 194 + 18 × carga pico ­ 110 × sexo" foram comparados com o VO2pico medido. Resultados: O VO2pico predito pela equação não foi diferente do VO2pico medido. Foi encontrada alta correlação entre os valores de VO2pico e, a análise Bland Altman não mostrou diferença significativa, demonstrando concordância entre os valores. Conclusão: A equação preditiva do VO2pico é válida para jovens brasileiros com espinha bífida e é uma alternativa vantajosa para obter e acompanhar o condicionamento físico e prescrever a intensidade de treinamento nesses indivíduos.

Cervical intramedullary teratoma: a case report and systematic review of the literature.

Here, we report a case of a 3-year-old female who presented to clinic with an enlarging mass in the posterior cervical midline. The mass was present since birth and demonstrated no cutaneous stigmata. Plain film, CT, and MRI of the cervical spine (C3-C5) revealed enlargement of the spinal canal, soft tissue calcification, spinal dysraphism, and an intramedullary, predominantly fatty, mass. The mass had associated calcifications and a highly proteinaceous cyst. Surgical resection of the spinal lesion was subsequently performed. Histopathological evaluation revealed a mature teratoma. Cervical spinal teratomas in the pediatric population are rare entities with few cases currently reported in the literature. We conducted a systematic review to outline the current evidence detailing cases of intramedullary spinal cord teratomas. Six articles were included for final review. All patients in the included articles underwent maximal surgical resection with one patient also receiving chemotherapy and radiation. With our report, we aim to add to the literature on cervical intramedullary spinal cord teratomas in the pediatric population.

Prenatal intracranial hypotension syndrome: new insights into the mechanisms of fenestration of septi pellucidi and ventriculomegaly in fetuses with open spinal dysraphism.

OBJECTIVE: To study the prevalence of abnormalities of the septi pellucidi (SP) in a cohort of fetuses with open spinal dysraphism (OSD) and to determine whether this condition is secondary to obstructive ventriculomegaly and, therefore, part of the natural history of prenatal intracranial hypotension (PICH) syndrome. METHODS: Magnetic resonance imaging (MRI) studies from fetuses with OSD were analyzed. The SP were assessed using axial and coronal T2-weighted images of the fetal brain and classified as intact, partially absent, or completely absent. Additionally, the correlation between the presence or absence of the SP and the size of the lateral ventricles, degree of cerebellar tonsillar herniation, collapse of the fourth ventricle, and interpeduncular angle was investigated. RESULTS: A total of 32 fetuses with OSD were studied. Mean gestational age at the time of the fetal MRI was 25.5 ± 3.9 weeks (range, 19-35) and mean ventricular size was 16.2 ± 4.2 mm (range, 8-26). Twenty-three (71.9%) fetuses had cerebellar tonsillar herniation. The IPA was completely collapsed in 23 cases (71.9%), reduced in seven (21.9%), and unreadable in two (6.3%). Twenty (62.5%) fetuses presented with intact SP, 10 (31.3%) with partially absent SP (incomplete fenestration), and two (6.3%) with completely absent SP (complete fenestration). Fenestration of the SP correlated significantly with the degree of ventriculomegaly (Pearson's correlation coefficient =0.459; p = .01). However, there was no correlation with the IPA, collapse of the fourth ventricle, and cerebellar tonsillar herniation. CONCLUSIONS: More than one-third of the fetuses with OSD had fenestration of the SP. The most probable etiology is increased intraventricular pressure leading to local necrosis of the SP. As fenestration of the SP is a secondary event associated with PICH syndrome, this condition should not be considered a contraindication for intrauterine repair of the spinal defect. Instead, it should be seen as an indicator of the severity of the intraventricular pressure.

Spinal dermal sinus complication in children: case series and literature review / Complicação do seio dérmico espinhalem crianças: séries de casos e revisão de literatura / Complicacióndel seno dérmico espinal en niños: serie de casos y revisión de la literatura

ABSTRACT Introduction: Dermal sinus (DS) is a rare dysraphism. It can be asymptomatic, become infected, and produce severe neurological symptoms. Our objective is to present a series of pediatric cases with spinal DS complicated byinfections (DSCI), describe the findings correlated with the anatomy in a stillbirth, as well as the associated pathologies and their treatment. Method: We analyzeddifferent variables in the clinical histories of 5 children with spinal DSCI. In addition, an anatomical dissection of a stillbirth with lumbar DS was performed. Results: Two males and 3 femaleswith DSCI and a mean age of 2 years and 9 months were included: 2 lumbar (one in the midline and the other in theparamedian region), 1 in the thoracic region, 1 in the upper cervical region,and 1 in the lumbosacral region. The forms of presentation were 3 meningeal profiles (one with pain andlocalized swelling) and 3 neurological deficits (one associated with the meningeal profile and another associated with pain and a tumor). In all cases, the tract of the DS was identified by magnetic resonance imaging (MRI).Associated lesions included 1 dorsal intramedullary dermoid cyst, 1 tethered lumbar spinal cord with syringomyelia, 1 partial cervical medullary disconnection, and 2 spinal dysraphisms. Four were operated on and one died of infectious complications before surgery. In the 12-week-old male fetus with lumbar DS, a permeable tract to the subarachnoid space was verified. Conclusions: DSCIsshould bestudied with MRI to identify their tracts, infectious complications of thecentral nervous system, associated malformations, inclusion tumors, and to enabledifferential diagnosis. Once diagnosed, they should be urgently treated both surgically and with prolonged antibiotictherapy. Level of Evidence IV; Therapeutic Study (Treatment Outcome Investigation)

RESUMO Introdução: O seio dérmico (SD) é uma disrafia rara. Pode ser assintomático, sofrer infecção e produzir quadros graves.Nosso objetivo é apresentar uma série de casos pediátricos com SDs espinhais complicados por infecções (SDCI),descrever os achados correlacionados com a anatomia em um natimorto, as patologias associadas e seu tratamento. Método: Foram analisadasas variáveis da históriaclínica em 5 crianças com SCDI espinhal.Além disso, foi feita uma dissecção anatômica de um natimorto com SD. Resultados: Foram incluídos 2 meninose 3 meninas, com média de idade de 2 anos e 9 meses, com SDCI: 2 lombares(um na linha média e um paramediano), 1 na região torácica, 1 na região cervical superior e 1 lombossacral. As formas de apresentação foram 3 quadros meníngeos, 1 com dor e tumefação lombar local e 3 déficits neurológicos (um associado ao quadro meníngeo e outro associado à dor e tumor). Em todos os casos, o trajeto do SD foi identificado por ressonância magnética (RM).Aslesões associadas foram 1 cisto dermoide intramedular dorsal, 1 medula ancorada lombar com siringomielia, 1 desconexão medular cervical parcial e 2 disrafias espinhais. Quatro participantes foram operados e um foi a óbito decorrente de complicações infecciosas antes da cirurgia.No feto masculino de 12 semanas com SD lombar, foi verificado um trajeto permeável até o espaçosubaracnóideo. Conclusões: Os SDCIs devem ser estudados com RM para identificar o seu trajeto, complicações infecciosas do sistema nervoso, malformações associadas, tumores de inclusão e permitir o diagnóstico diferencial. Eles devem ser tratados cirurgicamente com urgência uma vez diagnosticados e com tratamento prolongado com antibióticos.

Disrafismo Espinal Oculto: Reporte de Caso

RESUMEN El disrafismo espinal oculto incluye alteraciones en la fusión del tubo neural, en el que la lesión está cubierta por la epidermis, su incidencia estimada es de 0,5 a 5 casos por cada 1000 nacidos vivos. Los estigmas cutáneos pueden ser el único signo de la patología, los cuales pueden no ser muy evidentes. Reporte de caso de mujer de 36 años que acudió a consulta por cuadro de dolor lumbar de inicio insidioso, de 3 semanas de duración, que con el paso de los días se fue intensificando, irradia a miembros inferiores, cede parcialmente con analgésicos comunes y se acompaña de parestesias en ambos miembros. Se solicitó TAC y RMN que reveló anomalía anatómica sacrococcígea caracterizada por abertura de canal raquídeo, ausencia de cóccix, situación baja del cono medular, siringomielia e hiperintensidad a nivel del filum terminal sugestivo de lipoma. Se confirmó el diagnóstico de espina bífida oculta a nivel sacro, con lipoma del filum terminal, médula anclada con situación baja del cono medular y siringomielia asociada. Actualmente es controversial el beneficio cirugía profiláctica en pacientes asintomáticos, siendo preferible una conducta conservadora con estrecho seguimiento urológico y neurológico, entre las medidas de prevención se recomienda evitar el ejercicio físico extenuante, disminuir carga de columna lumbar y reeducación postural.

ABSTRACT Occult spinal dysraphism includes alterations in the fusion of the neural tube, in which the lesion is covered by the epidermis, its estimated incidence is 0.5 to 5 cases per 1000 live births. Cutaneous stigmata may be the only sign of pathology, which may not be very obvious. Case report of a 36-year-old woman who came to the clinic for insidious onset lumbar pain, lasting 3 weeks, which intensified over the days, radiating to the lower limbs, partially subsided with common analgesics and accompanied by paresthesias in both limbs. CT and MRI are requested, revealing sacrococcygeal anatomical abnormality characterized by spinal canal opening, absence of coccyx, low location of the medullary cone, syringomyelia, and hyperintensity at the level of the terminal filum suggestive of lipoma. The diagnosis of occult spina bifida at the sacral level was confirmed, with a lipoma of the terminal filum, an anchored cord with a low location of the medullary cone and associated syringomyelia. Currently, the benefit of prophylactic surgery in asymptomatic patients is controversial, being preferable a conservative behavior with close urological and neurological monitoring, among the prevention measures it is recommended to avoid strenuous physical exercise, reduce lumbar spine load and postural reeducation.

Mucocele frontal: reporte de caso

RESUMEN Los mucoceles de los senos paranasales son tumoraciones expansivas que muestran diferentes presentaciones y localizaciones. Son tumores benignos de crecimiento lento, pero debido a la expansión que presentan causan la erosión y desplazamiento de las estructuras adyacentes, la edad de presentación varía de los 40 a los 60 años, sin predilección por el sexo. Aproximadamente en el 60-65 % de casos afectan a los senos paranasales frontales. La clínica de presentación es variable y depende mucho del tamaño del mucocele, así como de su localización y tiempo de evolución, pueden permanecer asintomáticos por mucho tiempo y debutar con alguna complicación; en los de localización frontal los hallazgos más frecuentes son cefalea frontal, asimetría facial, alteraciones a nivel ocular como diplopía, proptosis ocular, disminución de la movilidad ocular, reducción de la agudeza visual, incluso pudiendo llegar a pérdida de la visión total en el ojo afecto; la expansión intracraneal también puede llevar a fístulas de líquido cefalorraquídeo, meningitis y abscesos cerebrales. En el diagnóstico es fundamental solicitar el par radiológico de tomografía y resonancia magnética con contraste para determinar la extensión real del mucocele, la afectación de las estructuras adyacentes y optar por la mejor terapéutica posible. Esta patología es de manejo quirúrgico, el objetivo es abrir la cavidad del mucocele para lograr una adecuada ventilación y drenaje del seno afecto, actualmente la cirugía endoscópica nasal o combinada es la terapéutica más empleada.

ABSTRACT Mucoceles of the paranasal sinuses are expansive tumors that show different presentations and locations. They are benign tumors of slow growth, but due to their expansion they cause erosion and displacement of adjacent structures. The age of presentation varies from 40 to 60 years old, with no gender predilection. Approximately 60-65% of cases affect the frontal paranasal sinuses. The clinical presentation is variable and depends on the size of the mucocele, as well as its location and time of evolution, they can remain asymptomatic for a long time and debut with some complication; In frontal mucoceles the most frequent findings are frontal headache, facial asymmetry, ocular alterations such as diplopia, ocular proptosis, decreased ocular mobility, reduced visual acuity, and even total loss of vision in the affected eye; intracranial expansion can also lead to cerebrospinal fluid fistulas, meningitis and brain abscesses. In the diagnosis it is essential to request the radiological pair of tomography and magnetic resonance with contrast to determine the real extension of the mucocele, the affectation of the adjacent structures and to opt for the best possible therapy. This pathology is of surgical management, the objective is to open the mucocele cavity to achieve an adequate ventilation and drainage of the affected sinus, currently the nasal endoscopic or combined surgery is the most used therapy.

Myelomeningocele defect reconstruction with keystone flaps: vascular rationale for the design and operative technique.

BACKGROUND: Myelomeningocele is a frequently seen condition at tertiary care hospitals. Its treatment involves a variety of plastic reconstructive techniques. Herein, we present a series of myelomeningocele patients treated using keystone flaps. METHODS: We gathered information regarding soft tissue reconstruction and the use of bilateral keystone flaps to treat myelomeningocele patients. We obtained data from clinical records and recorded the demographic characteristics of mothers and children with the condition. The size, level of defect, and complications detected during the follow-up were analyzed. RESULTS: A series of seven patients who underwent bilateral keystone flaps for myelomeningocele closure was analyzed. There were no cases of midline or major dehiscence, flap loss, necrosis, surgical site infections, or cerebrospinal fluid leakage. No revision procedures were performed. Minor complications included one case with minimal seroma and three cases with areas of peripheral dehiscence that healed easily using conventional measures. CONCLUSIONS: The use of keystone flaps is an adequate option for closure of dorsal midline soft tissue defects related to myelomeningocele. This technique offers predictable results with an acceptable spectrum of complications. Robust blood flow can be predicted based upon anatomical knowledge.

Neurocirugía transicional: ¿una nueva subespecialidad? / Transitional neurosurgery: a new subspecialty?

Introducción: El proceso de transición de un paciente de la etapa pediátrica a la adulta es un proceso dinámico, complejo y planificado, que incluye la transferencia propiamente dicha de una institución pediátrica a una adulta. El aumento de la sobrevida de niños y adolescentes con patologías crónicas, la falta de acuerdos formales entre instituciones de salud y la falta de enfoque multidisciplinario de estos casos son los principales problemas a tener en cuenta. El objetivo del presente trabajo es describir y proponer una respuesta a las situaciones y dificultades que se encuentran en la actualidad en la salud pública durante el proceso de transición de pacientes pediátricos con patología neuroquirúrgica crónica y de pacientes adultos con patología congénita. Para tal fin se deben considerar factores sociales, económicos y comunicacionales. Material y Método: Estudio observacional, transversal y retrospectivo de pacientes con patología neuroquirúrgica transicional desde el 01 de enero de 2017 al 31 de diciembre de 2018. En total se revisaron las historias clínicas de 47 pacientes del Hospital "El Cruce". Resultados: De los 47 pacientes observados, con un rango etario entre 17 y 42 años, realizamos una división de éstos en 2 grupos: GRUPO 1: pacientes adultos operados en la edad pediátrica que requieren un seguimiento crónico de su patología de origen; y GRUPO 2: pacientes adultos con patología congénita. En el GRUPO 1, observamos 38 pacientes (24 masculinos y 14 femeninos) de los cuales 24 fueron operados y 14 no operados (solo seguimiento clínico). Dentro de este grupo, el 63% de los pacientes (n=29) presentó como su patología de base para su seguimiento la hidrocefalia. En el GRUPO 2, observamos a 9 pacientes (2 masculinos y 7 femeninos) de los cuales 7 fueron operados y 2 no operados. Todos los pacientes de este último grupo presentaron como diagnóstico de base un disrafismo espinal. Conclusión: Se debe lograr una transición planificada para el bienestar de los jóvenes con necesidades especiales de atención de salud. Actualmente no hay acuerdos interinstitucionales formales para el seguimiento y atención de estos pacientes.Consideramos que existe un grupo de pacientes que se beneficiarían con la creación de una nueva subespecialidad neuroquirúrgica: la neurocirugía transicional. La misma debería desarrollarse en hospitales generales, de alta complejidad, donde coincidan en el servicio de neurocirugía de adultos, neurocirujanos con formación pediátrica

Introduction: The transition process of a patient from pediatric to adult stage is a dynamic, complex, and planned process which, strictly speaking, includes the transfer from a pediatric to an adult institution. The increased rate of survival of children and adolescents with chronic pathologies, lack of formal agreements between health institutions and lack of multidisciplinary approach to these cases are the main issues to consider. The purpose of this paper is to describe and provide a response to situations and difficulties that currently exist in the public health during the transition process of pediatric patients with chronic neurosurgical pathology and adult patients with congenital pathology. For this purpose, communication, social, and economic factors must be considered. Methods: Observational, cross-sectional, and retrospective study of patients with transitional neurosurgical pathology from January 1, 2017, to December 31, 2018. In total, 47 patient's medical records were reviewed from "El Cruce" Hospital. Results: A total of 47 patients, with an age range between 17 and 42 years, were observed. We divided our study population into 2 groups: GROUP 1: adult patients who have been operated in pediatric age and require chronic follow-up of their origin pathology; and GROUP 2: adult patients with congenital pathology. In GROUP 1, we observed 38 patients (24 male and 14 female) of whom 24 were performed neurosurgery, and 14 were not. Within this group, 63% of the patients (n = 29) presented hydrocephalus as their basic pathology for monitoring. In GROUP 2, we observed 9 patients (2 male and 7 female) of whom 7 were operated and 2 were not. All patients in this last group presented spinal dysraphism as their basic diagnosis. Conclusion: A planned transition for the well-being of young patients with special health care needs must be achieved. Currently, there are no formal institutional agreements for the monitoring and care of these patients. We believe that there is a group of patients who would benefit from the creation of a new neurosurgical sub-specialty: transitional neurosurgery. It should be developed in high complexity general hospitals, where neurosurgeons with pediatric training could be part of a general neurosurgery department.

Agenesia caudal con disrafismo espinal cerrado, reporte de un caso / Caudal agenesis with closed spinal dysraphism, a case report / Caudal agenesis with closed spinal dysraphism, a case report

RESUMEN La agenesia caudal es una patología poco frecuente; es difícil su diagnóstico y evaluación fetal. La presencia de disrafismo espinal cerrado a nivel del sacro debe obligarnos a evaluar la anatomía del sacro. La visualización del cono medular es una forma muy útil en la evaluación y descarte de disrafismo espinal cerrado y agenesia caudal. Comunicamos un caso poco frecuente de agenesia caudal.

ABSTRACT Caudal agenesis is a rare pathology, its diagnosis and fetal evaluation are complex. The presence of closed spinal dysraphism at the level of the sacrum should compel us to evaluate the anatomy of the sacrum. The evaluation of the medullary cone is very useful to evaluate and exclude closed spinal dysraphism and caudal agenesis. We report a rare case of caudal agenesis.
