  • AI-Based Models to Predict Decompensation on Traumatic Brain Injury Patients.
    Publication . Ribeiro, Ricardo; Neves, Inês; Oliveira, Hélder P; Pereira, Tania
    Traumatic Brain Injury (TBI) is a form of brain injury caused by external forces, resulting in temporary or permanent impairment of brain function. Despite advancements in healthcare, TBI mortality rates can reach 30%-40% in severe cases. This study aims to assist clinical decision-making and enhance patient care for TBI-related complications by employing Artificial Intelligence (AI) methods and data-driven approaches to predict decompensation. This study uses learning models based on sequential data from Electronic Health Records (EHR). Decompensation prediction was performed based on 24-h in-mortality prediction at each hour of the patient's stay in the Intensive Care Unit (ICU). A cohort of 2261 TBI patients was selected from the MIMIC-III dataset based on age and ICD-9 disease codes. Logistic Regressor (LR), Long-short term memory (LSTM), and Transformers architectures were used. Two sets of features were also explored combined with missing data strategies by imputing the normal value, data imbalance techniques with class weights, and oversampling. The best performance results were obtained using LSTMs with the original features with no unbalancing techniques and with the added features and class weight technique, with AUROC scores of 0.918 and 0.929, respectively. For this study, using EHR time series data with LSTM proved viable in predicting patient decompensation, providing a helpful indicator of the need for clinical interventions.
  • Subdural Hematoma as a Complication of Endoscopic Third Ventriculostomy in a Pediatric Patient: a Case Report and Literature Review.
    Publication . Fernandes, Rafael Tiza; Sobrinho, Rui; Azevedo, Miguel; Matos, Mário; Sagarribay, Amets; Forte, Dalila
    Background: Subdural hematoma (SDH) typically occurs due to traumatic brain injury but can arise as a rare complication of procedures like endoscopic third ventriculostomy (ETV). Case presentation: We report an unusual case in a 9-year-old male with previous resection of a fourth-ventricle ependymoma at 2 years of age. Seven years post-surgery, he presented with worsening hydrocephalus and underwent ETV. One month later, he developed severe headaches and motor difficulties. Imaging revealed a significant right SDH, necessitating urgent drainage. Postoperative recovery was uneventful, and follow-up imaging showed resolution of the hematoma. Literature review and discussion: ETV is generally preferred for obstructive hydrocephalus due to lower complication rates compared to shunt procedures. However, cases of SDH post-ETV remain reported, albeit rarely. Potential mechanisms include altered cerebrospinal fluid dynamics and intraoperative vessel injury. This case aligns with literature findings and reinforces the importance of postoperative monitoring and prompt intervention in symptomatic cases to prevent complications. Conclusion: Clinicians should consider SDH in pediatric patients with new symptoms post-ETV. Further research should focus on understanding the risk factors and mechanisms for SDH development.

    Publication . Massimi, L; Cinalli, G; Frassanito, P; Arcangeli, V; Auer, C; Baro, V; Bartoli, A; Bianchi, F; Dietvorst, S; Di Rocco, F; Gallo, P; Giordano, F; Hinojosa, J; Iglesias, S; Jecko, V; Kahilogullari, G; Knerlich-Lukoschus, F; Laera, R; Locatelli, D; Luglietto, D; Luzi, M; Messing-Jünger, M; Mura, R; Ragazzi, P; Riffaud, L; Roth, J; Sagarribay, A; Pinheiro, M Santos; Spazzapan, P; Spennato, P; Syrmos, N; Talamonti, G; Valentini, L; Van Veelen, M L; Zucchelli, M; Tamburrini, G
    Background: COVID-19 pandemic is thought to have changed the epidemiology of some pediatric neurosurgical disease: among them are the intracranial complications of sinusitis and otitis (ICSO). According to some studies on a limited number of cases, both streptococci-related sinusitis and ICSO would have increased immediately after the pandemic, although the reason is not clear yet (seasonal changes versus pandemic-related effects). The goal of the present survey of the European Society for Pediatric Neurosurgery (ESPN) was to collect a large number of cases from different European countries encompassing the pre-COVID (2017-2019), COVID (2020-2021), and post-COVID period (2022-June 2023) looking for possible epidemiological and/or clinical changes. Material and methods: An English language questionnaire was sent to ESPN members about year of the event, patient's age and gender, presence of immune-deficit or other favoring risk factors, COVID infection, signs and symptoms at onset, site of primary infection, type of intracranial complication, identified germ, type and number of surgical operations, type and duration of medical treatment, clinical and radiological outcome, duration of the follow-up. Results: Two hundred fifty-four cases were collected by 30 centers coming from 14 different European countries. There was a statistically significant difference between the post-COVID period (129 children, 86 cases/year, 50.7% of the whole series) and the COVID (40 children, 20 cases/year, 15.7%) or the pre-COVID period (85 children, 28.3 cases/year, 33.5%). Other significant differences concerned the presence of predisposing factors/concurrent diseases (higher in the pre-COVID period) and previous COVID infection (higher in the post-COVID period). No relevant differences occurred as far as demographic, microbiological, clinical, radiological, outcome, morbidity, and mortality data were concerned. Paranasal sinuses and middle ear/mastoid were the most involved primary site of infection (71% and 27%, respectively), while extradural or subdural empyema and brain abscess were the most common ICSO (73% and 17%, respectively). Surgery was required in 95% of cases (neurosurgical and ENT procedure in 71% and 62% of cases, respectively) while antibiotics in 99% of cases. After a 12.4-month follow-up, a full clinical and radiological recovery was obtained in 85% and 84% of cases, respectively. The mortality rate was 2.7%. Conclusions: These results suggest that the occurrence of ICSO was significantly increased after the pandemic. Such an increase seems to be related to the indirect effects of the pandemic (e.g., immunity debt) rather than to a direct effect of COVID infection or to seasonal fluctuations. ICSO remain challenging diseases but the pandemic did not affect the management strategies nor their prognosis. The epidemiological change of sinusitis/otitis and ICSO should alert about the appropriate follow-up of children with sinusitis/otitis.
  • Idiopathic Spinal Cord Herniation - An Extremely Rare Cause of Paraparesis: Case Report
    Publication . De Smet, Bernardo; Pinheiro, Teresa; Fonseca, Lino
    Idiopathic spinal cord herniation is a rare disorder, consisting of a ventral displacement of the spinal cord through a dural defect. The resulting adhesion and vascular compromise lead to neurological impairment. We report the case of a 54yearold male, with a previous urological surgery resulting in chronic vesical catheterization, with a worsening paraparesis associated with anesthesia below T10. The magnetic resonance imaging showed a ventral displacement of the spinal cord at T7/T8 with an enlarged posterior subarachnoid space at that level. A fourlevel laminotomy was performed followed by spinal cord herniation reduction and closure of the anterior dural defect with a dural replacement. The patient had a partial recovery of his motor deficits regaining his ability to walk with the support of a single crutch. The purpose of this study was to highlight the existence of this extremely rare cause of paraparesis, which is often misdiagnosed.

    Publication . Rebelo, M; Francisco, T; Perry da Câmara, R; Pereira, A; Iraneta, A; Amorim, M; Paiva Lopes, MJ; Lopes da Silva, R; Cordeiro, AI
    Introduction: Neurocutaneous syndromes (NCS) are a heterogeneous group of conditions with multiorgan involvement and diverse manifestations, evolving throughout life with significant morbidity. A multidisciplinary approach to NCS patients has been advocated, although a specific model is not yet established. The aim of this study was 1) to describe the organization of the recently created Multidisciplinary Outpatient Clinic of Neurocutaneous Diseases (MOCND) at a Portuguese pediatric tertiary hospital; 2) to share our institutional experience focusing on the most common conditions, neurofibromatosis type 1 (NF1) and tuberous sclerosis complex (TSC); 3) to analyze the advantages of a multidisciplinary center and approach in NCS. Methods: Retrospective analysis of 281 patients enrolled in the MOCND over the first five years of activity (October 2016 to December 2021), reviewing genetics, family history, clinical features, complications, and therapeutic strategies for NF1 and TSC. Results: The clinic works weekly with a core team of pediatricians and pediatric neurologists supported by other specialties as needed. Of the 281 patients enrolled, 224 (79.7%) had identifiable syndromes such as NF1 (n = 105), TSC (n = 35), hypomelanosis of Ito (n = 11), Sturge-Weber syndrome (n = 5), and others. In NF1 patients, 41.0% had a positive family history, all manifested café-au-lait macules, 38.1% neurofibromas with 45.0% being large plexiform neurofibromas. Sixteen were under treatment with selumetinib. Genetic testing was performed in 82.9% of TSC patients with pathogenic variants found in TSC2 gene in 72.4% patients (82.7% if considered contiguous gene syndrome). Family history was positive in 31.4%. All TSC patients presented hypomelanotic macules and fulfilled diagnostic criteria. Fourteen patients were being treated with mTOR inhibitors. Conclusion: Offering a systematic and multidisciplinary approach to NCS patients enables timely diagnosis, promotes a structured follow-up, and encourages discussion to outline management plans for optimal care to every patient, with significant impact on the quality of life of patients and families.
  • Langerhans Cell Histiocytosis in the Occipital Condyle: A Case Study and a Brief Review of the Literature
    Publication . Barbosa, NC; Ramos, A; Sagarribay, A; Ribeiro, MJ
    We present a case study of a 5-year-old patient, who presented with left-sided torticollis. Due to persistence of problems, a CT and an MRI were made showing a single osteolytic lesion centred on right occipital condyle. After an open biopsy, histology confirmed it to be Langerhans cell histiocytosis (LCH). Torticollis or restricted range of motion is a presenting feature in 76% of children with LCH with cervical involvement. There remains much debate on the best treatment strategy. The clinical and radiological outcomes of the case study presented on this article support the treatment of LCH with chemotherapy in cases with solitary involvement of the occipital condyle.
  • Periodontoid Pseudotumor in Tuberous Sclerosis Associated With Neck Diffuse Lipomatosis
    Publication . Pinto, E; Veiga, M; Sagarribay, A; Conceição, C
    Tuberous sclerosis (TS) is a genetic multisystem disorder associated with the development of benign tumors in many organs. Diffuse lipomatosis, which represents the overgrowth of fatty tissue in one part of the body, is a very rare finding reported in patients with tuberous sclerosis. We describe the case of a patient with diffuse lipomatosis in the right scapular, posterior cervical and perivertebral regions, associated with a space-occupying lesion adjacent to the odontoid process of C2 that appeared to be a pseudotumor, and discuss possible relation between these entities.
  • Cerebrospinal Fluid Hypotension Following Fall in a Child: Case Report
    Publication . Botelho, G; Grilo, RD; Almeida, VD; Romão, P; Gomes, S; Sagarribay, A
    CSF hypotension arises in the context of a leak of CSF which causes negative intracranial pressure. Sacral fractures result from high-energy trauma which are frequently underdiagnosed. A ten-year-old boy presented with hip pain, after a fall. He mobilized both lower limbs, reported no leg pain, irradiation nor lack of sphincter control. The neurological examination was normal. When asked to stand, he began biparietal headache, nausea and vomiting, which improved laying down. CT scan showed an occult intrasacral meningocele; the MRI revealed collections of CSF along the spine, a S3 fracture with potential laceration of the meningocele and opening of a CSF fistula. Our diagnosis was the CSF hypotension, secondary to the fistula opening. The diagnosis was challenging. The child first presented with symptoms of CSF hypotension without evident cause. The discovery of the meningocele led us to hypothesize the opening of a fistula, a rare diagnosis, later confirmed by MRI.
  • Avaliação da Dor na Pessoa Idosa com Demência
    Publication . Bentes Pinto, AF
    Com o envelhecimento da população, aumenta também a prevalência da demência. Devido às várias comorbilidades associadas ao envelhecimento, a dor é um sintoma comum nesta população especial. Os défices cognitivos e alterações comportamentais associados à demência, dificultam o auto relato da experiência de dor, tornando mais complexa a sua avaliação. Como consequência, os idosos com demência, têm frequentemente a dor subavaliada e subtratada. Objetivo: Fazer uma revisão do tema focando os princípios gerais na avaliação e tratamento da dor e escalas comportamentais validadas e adaptadas culturalmente para a língua portuguesa. Metodologia: Foi realizada uma revisão narrativa da literatura com pesquisa nas bases de dados EBSCOhost - research databases (CINAHL Plus with full text; Nursing & Allied Health Collection full text; Cochrane Plus Collection full text; MedicLatina e MEDLINE with full text.) e Google académico de artigos em inglês e português publicados entre janeiro de 1999 e dezembro de 2016. Resultados: A avaliação da dor na pessoa idosa é um processo complexo. É necessário seguir alguns princípios gerais para a sua avaliação, existindo várias escalas comportamentais para tentar dar resposta a este problema. Conclusão: É imprescindível a utilização destes instrumentos de avaliação específicos, seguindo as boas práticas no controle e gestão da dor, permitindo assim uma melhoria da qualidade de vida. Especialmente nesta população específica, o enfermeiro assume um papel relevante na avaliação e controle da dor.
