    SPINE METASTASIS OF INTRACRANIAL HEMANGIOPERICYTOMA: CASE REPORT OF TWO TREATMENTS
    (2019) ARAUJO, Fernando Flores de; NARAZAKI, Douglas Kenji; TEIXEIRA, William Gemio Jacobsen; MARCON, Raphael Martus; CRISTANTE, Alexandre Fogaca; BARROS FILHO, Tarcisio Eloy Pessoa
    Objective: To report the use of two techniques (radiosurgery and en bloc vertebrectomy) on the same patient for the treatment of two metastases in different sites of the spine arising from intracranial hemangiopericytoma. Intracranial hemangiopericytomas are rare, comprising approximately 2.4% of meningeal tumors and <1% of all tumors of the central nervous system. Metastases to the spine are even rarer: The largest case series reported in the literature has 5 and 7 cases. Methods: A 37-year-old man diagnosed with intracranial hemangiopericytoma was referred for a metastatic lesion in T12 and underwent en bloc resection using the Tomita technique. Results: The disease evolved with a metastasis to T2 treated by radiosurgery with 1600 cGy. The patient died 1,706 days after the en bloc resection of T12 and 1324 days after the radiosurgery of T2, and no recurrence occurred in these locations due to progression of the systemic diseases (liver and central nervous system). Conclusion: This is the first case reported in the literature in which two different techniques were used to treat metastatic lesions in the spine from an intracranial hemangiopericytoma and is unique for its use of two treatments in the same patient.

    A COMPUTERIZED SYSTEM FOR THE APPLICATION OF BASSO, BEATTIE AND BRESNAHAN SCALE IN WISTAR RATS
    (2015) MOLINA, Alessandra Eira Iague Sleiman; CRISTANTE, Alexandre Fogca; BARROS FILHO, Tarcisio Eloy Pessoa de; MOLINA, Marcos Sleiman; MOLINA, Taina Peral
    Objectives: To develop and test a computer program to assist researchers in assigning scores in the application of the Basso, Beattie and Bresnahan (BBB) scale and to compare these scores when doing so in free, targeted and automated computer-assisted modes. Method: To test the program, the participants used the Impactor methodology recommended by the New York University (USA), in which 12 Wistar rats submitted to spinal cord injury were filmed on the 28th day after the injury. Eight researchers from the Laboratory of Medical Investigation, Faculdade de Medicina da Universidade de Sao Paulo, SP, Brazil took part in the study. The two heads of the laboratory, with 15 years of experience in the application of the scale, were considered the gold standard. Results: The results of the scale application were not significantly different in relation to the gold standard, considering the mean of the evaluators in each method: free, targeted and automated form (with the help of the computer). Conclusions: The application of the BBB scale in the automated mode, using the computer program, did not present any difference in relation to the gold standard for all the evaluators.

    Clinical and Radiological Results After Minimally Invasive Transpsoas Lateral Access Surgery for Degenerative Lumbar Stenosis
    (2020) COUTINHO, Thiago Pereira; CRISTANTE, Alexandre Fogaca; MARCON, Raphael Martus; ROCHA, Ivan Dias da; ONO, Allan Hiroshi; MEYER, Guilherme Pereira Correa; BARROS FILHO, Tarcisio Eloy de Pessoa
    Study Design: Prospective cohort study. Objective: The lateral transpsoas access is a retroperitoneal approach for the lumbar spine to perform the lateral lumbar interbody fusion (LLIF), an intersomatic arthrodesis performed with a cage placed on the lateral borders of the epiphyseal ring. The procedure can be used to provide indirect decompression of the nervous structures through the discectomy and restoration of the disc height. The objective of the present study was to evaluate the indirect decompression following LLIF both with radiological and clinical parameters. Methods: Prospective clinical and radiological study in a single center with 20 patients diagnosed with 1- or 2-level degenerative lumbar stenosis. Radiological analysis on magnetic resonance imaging included foramen height, canal area, canal diameter, and disc height. Clinical outcomes included visual analogue scale (VAS) and Oswestry Disability Index (ODI) collected up to 12 months. Complications and reoperations were recorded. Results: In total, 25 levels were treated. No reoperation was required. Disc height was increased by an average of 25% (P < .001). The canal area increased from 109 to 149 mm(2) (P < .001) and from 9.3 to 12.2 mm (P < .001) in anteroposterior diameter. The foramen area demonstrated the effect of indirect decompression on both sides (P < .001). The height of the foramen showed significant average increase of 2.8 mm (P < .001). The results from VAS and ODI questionnaires confirmed the clinical effect of indirect decompression. Conclusion: We observed that indirect decompression by the LLIF method is feasible both radiologically and clinically with a low rate of complications and reoperations.

    (2021) ONO, Allan Hiroshi de Araujo; CHANG, Veronica Yulin Prieto; RODENBECK, Erico Myung; ARAUJO, Alex Oliveira de; OLIVEIRA, Rafael Garcia de; MARCON, Raphael Martus; CRISTANTE, Alexandre Fogaca; BARROS FILHO, Tarcisio Eloy Pessoa
    Study Design: Cohort study. Objectives: This study aimed to evaluate the accuracy of the AO Surgery Reference mobile app in the diagnosis of thoracolumbar fractures of the spine according to the AO TL classification, and to discuss the usefulness of this app in the teaching and training of the resident physicians in orthopedics and traumatology area. Methods: The 24 residents of Orthopedic and Traumatology program assessed 20 cases of thoracolumbar fractures selected from the hospital database on 2 different occasions, with a 30-day interval, and they classified these cases with and without using the AO Surgery Reference app. A group of spine experts previously established the gold standard and the answers were statistically compared, with the inter- and intraobserver reliability evaluated by the kappa index. Results: The use of the AO Surgery Reference app increased the classification success rate of the fracture morphology (from 53.4% to 72.5%), of the comorbidity modifier (from 61.4% to 77.9%) and of the neurological status modifier (from 55.1% to 72.9%). In addition, the mobile app raised the classification agreement and accuracy. The kappa index increased from 0.30 to 0.53 regarding the morphological classification of fractures. Conclusions: The residents improved their ability to recognize and classify thoracolumbar spine fractures, which reinforces the importance of this tool in medical education and clinical practice.

    (2011) SANTOS, Gustavo Bispo dos; CRISTANTE, Alexandre Fogaca; MARCON, Raphael Martus; SOUZA, Fabiano Inacio de; BARROS FILHO, Tarcisio Eloy Pessoa de; DAMASCENO, Marcelo Loquette
    Objectives: To determine a standardized spinal cord contusion model and a method for motor assessment in rats with paraplegia. Methods: This study used 20 Wistar rats divided into 4 groups according to level of severity of spinal cord injury; standardized intermediate lesions were made through system MASCIS IMPACTOR (Multicenter Animal Spinal Cord Injury Study): group 1, 12.5mm (mild injury); group 2,25mm (moderate injury); group 3,50mm (severe injury; in the group 4 the animals suffered no injury (control group). Motor function was assessed after 48 hours, using the scale proposed by Basso, Beattie and Bresnahan. Results: Using the model, we observed that the mild contusions (12.5mm height) were effective, and the animals presented acute urinary tract infection one week after the injury. Moderate contusions (25mm height) were effective, and the animals presented urinary infection until 2 weeks after injury. The severe contusions (50mm height) were effective, and the animals presented urinary infection for 3 to 4 weeks and autophagy. Conclusion: The model of spinal cord injury using the system MASCIS IMPACTOR and the functional assessment proposed by Basso, Beattie and Bresnahan is reproducible and can be used, enabling information exchange among different researchers.

    (2024) RITTO, Ana Paula; ARAUJO, Adriana Ladeira de; CARVALHO, Carlos Roberto Ribeiro de; SOUZA, Heraldo Possolo De; FAVARETTO, Patricia Manga e Silva; SABOYA, Vivian Renata Boldrim; GARCIA, Michelle Louvaes; KULIKOWSKI, Leslie Domenici; KALLAS, Esper Georges; PEREIRA, Antonio Jose Rodrigues; COBELLO JUNIOR, Vilson; SILVA, Katia Regina; ABDALLA, Eidi Raquel Franco; SEGURADO, Aluisio Augusto Cotrim; SABINO, Ester Cerdeira; RIBEIRO JUNIOR, Ulysses; FRANCISCO, Rossana Pulcineli Vieira; MIETHKE-MORAIS, Anna; LEVIN, Anna Sara Shafferman; SAWAMURA, Marcio Valente Yamada; FERREIRA, Juliana Carvalho; SILVA, Clovis Artur; MAUAD, Thais; GOUVEIA, Nelson da Cruz; LETAIF, Leila Suemi Harima; BEGO, Marco Antonio; BATTISTELLA, Linamara Rizzo; DUARTE, Alberto Jose da Silva; SEELAENDER, Marilia Cerqueira Leite; MARCHINI, Julio; FORLENZA, Orestes Vicente; ROCHA, Vanderson Geraldo; MENDES-CORREA, Maria Cassia; COSTA, Silvia Figueiredo; CERRI, Giovanni Guido; BONFA, Eloisa Silva Dutra de Oliveira; CHAMMAS, Roger; BARROS FILHO, Tarcisio Eloy Pessoa de; BUSATTO FILHO, Geraldo
    Introduction The COVID-19 pandemic has prompted global research efforts to reduce infection impact, highlighting the potential of cross-disciplinary collaboration to enhance research quality and efficiency.Methods At the FMUSP-HC academic health system, we implemented innovative flow management routines for collecting, organizing and analyzing demographic data, COVID-related data and biological materials from over 4,500 patients with confirmed SARS-CoV-2 infection hospitalized from 2020 to 2022. This strategy was mainly planned in three areas: organizing a database with data from the hospitalizations; setting-up a multidisciplinary taskforce to conduct follow-up assessments after discharge; and organizing a biobank. Additionally, a COVID-19 curated collection was created within the institutional digital library of academic papers to map the research output.Results Over the course of the experience, the possible benefits and challenges of this type of research support approach were identified and discussed, leading to a set of recommended strategies to enhance collaboration within the research institution. Demographic and clinical data from COVID-19 hospitalizations were compiled in a database including adults and a minority of children and adolescents with laboratory confirmed COVID-19, covering 2020-2022, with approximately 350 fields per patient. To date, this database has been used in 16 published studies. Additionally, we assessed 700 adults 6 to 11 months after hospitalization through comprehensive, multidisciplinary in-person evaluations; this database, comprising around 2000 fields per subject, was used in 15 publications. Furthermore, thousands of blood samples collected during the acute phase and follow-up assessments remain stored for future investigations. To date, more than 3,700 aliquots have been used in ongoing research investigating various aspects of COVID-19. Lastly, the mapping of the overall research output revealed that between 2020 and 2022 our academic system produced 1,394 scientific articles on COVID-19.Discussion Research is a crucial component of an effective epidemic response, and the preparation process should include a well-defined plan for organizing and sharing resources. The initiatives described in the present paper were successful in our aim to foster large-scale research in our institution. Although a single model may not be appropriate for all contexts, cross-disciplinary collaboration and open data sharing should make health research systems more efficient to generate the best evidence.

    Prediction of intensive care admission and hospital mortality in COVID-19 patients using demographics and baseline laboratory data
    (2023) AVELINO-SILVA, Vivian I.; AVELINO-SILVA, Thiago J.; ALIBERTI, Marlon J. R.; FERREIRA, Juliana C.; COBELLO JUNIOR, Vilson; SILVA, Katia R.; POMPEU, Jose E.; ANTONANGELO, Leila; MAGRI, Marcello M.; BARROS FILHO, Tarcisio E. P.; SOUZA, Heraldo P.; KALLAS, Esper G.
    Introduction: Optimized allocation of medical resources to patients with COVID-19 has been a critical concern since the onset of the pandemic.Methods: In this retrospective cohort study, the authors used data from a Brazilian tertiary university hospital to explore predictors of Intensive Care Unit (ICU) admission and hospital mortality in patients admitted for COVID19. Our primary aim was to create and validate prediction scores for use in hospitals and emergency departments to aid clinical decisions and resource allocation. Results: The study cohort included 3,022 participants, of whom 2,485 were admitted to the ICU; 1968 survived, and 1054 died in the hospital. From the complete cohort, 1,496 patients were randomly assigned to the derivation sample and 1,526 to the validation sample. The final scores included age, comorbidities, and baseline laboratory data. The areas under the receiver operating characteristic curves were very similar for the derivation and validation samples. Scores for ICU admission had a 75% accuracy in the validation sample, whereas scores for death had a 77% accuracy in the validation sample. The authors found that including baseline flu-like symptoms in the scores added no significant benefit to their accuracy. Furthermore, our scores were more accurate than the previously published NEWS-2 and 4C Mortality Scores.Discussion and conclusions: The authors developed and validated prognostic scores that use readily available clinical and laboratory information to predict ICU admission and mortality in COVID-19. These scores can become valuable tools to support clinical decisions and improve the allocation of limited health resources.

    (2011) PONTIN, Pedro Augusto; BUMLAI, Renam Urt Mansur; LETAIF, Olavo Biraghi; DAMASCENO, Marcelo Loquette; CRISTANTE, Alexandre Fogaca; MARCON, Raphael Martus; IUTAKA, Alexandre Sadao; OLIVEIRA, Reginaldo Perilo; BARROS FILHO, Tarcisio Eloy Pessoa de
    Objective: This article describes a clinical and radiologic retrospective analysis of odontoid fractures in 20 patients accompanied by the IOT-HCFMUSP, from 2004 to 2010. Methods: These fractures were stratified according to their classification (AO/Anderson and D'Alonzo), epidemiologic profile, type of treatment, time to consolidation of the fracture, and complications. Results: It was observed that there was a higher number of odontoid fractures in males (4: 1), between the third and fourth decades of life (60%), and that the main causes of the trauma were falling from heights (60%) and car accidents (25%). Also, 15% of the cases presented neurological deficits. The most prevalent type of odontoid fracture was Type II (55%) followed by Type III (40%). The most prevalent type of treatment used for Type II and III fractures was surgical (73%) and non-surgical (87.5%), respectively. Consolidation of the fracture took place within 16 weeks in 87.5% of surgically treated cases, and in 54.5% of those treated non-surgically. No cases of pseudoarthrosis were found. Conclusion: The surgical treatment of Type II odontoid fractures showed satisfactory results in relation to time to consolidation of the fracture and low incidence of complications, as did the non-surgical treatment used for the Type III fractures. Level of Evidence: Level IV, case series.

    FOUR-LEVEL EN BLOC VERTEBRECTOMY: A NOVEL TECHNIQUE AND LITERATURE REVIEW
    (2018) NARAZAKI, Douglas Kenji; HIGINO, Lucas P.; TEIXEIRA, William Gemio Jacobsen; ROCHA, Ivan Dias da; CRISTANTE, Alexandre Fogaca; BARROS FILHO, Tarcisio Eloy Pessoa de
    Objective: To demonstrate a novel technique for multilevel en bloc post-vertebrectomy reconstruction. Methods: A novel technique for en bloc multiple post-vertebrectomy reconstruction was used in a patient presenting for curative resection of Ewing's Sarcoma at the oncology center of a public university hospital. Results: The procedure described was feasible for en bloc resection of the four vertebrae. The reconstruction was acceptable and satisfactory in terms of mechanical stability and was without any neurological sequelae in the patient. Conclusion: The use of an allograft with a locked intramedullary nail was an adequate solution for reconstructing the anterior and medial spines after multilevel vertebrectomy. In addition, the association of four intramedullary nails provided stability to the reconstruction. Immediate benefits of the technique compared to other commonly used techniques were shorter hospitalization times and reduced surgical morbidity.

    SACRECTOMY ASSOCIATED WITH VERTEBRECTOMY: A NEW TECHNIQUE USING DOWEL GRAFTS FROM CADAVERS
    (2018) ARAUJO, Thiego Pedro Freitas; NARAZAKI, Douglas Kenji; TEIXEIRA, William Gemio Jacobsen; BUSNARDO, Fabio; CRISTANTE, Alexandre Fogaca; BARROS FILHO, Tarcisio Eloy Pessoa de
    Objective: The purpose of this study was to demonstrate, in a case series, a new sacrectomy technique using an iliac crest dowel graft from a cadaver. Study design: Report of a case series with description of a new surgical technique. Methods: The technique uses four bars to support the posterior spine and a dowel graft in the iliac wings, with compression of the spine and pelvis above it, to support the anterior spine. Three cases were operated on, and in all of them, a vertebrectomy was used. Results: In the first two cases, the technique was performed as a two-stage surgery. The first stage was performed via the anterior and peritoneal access routes, and the second stage via the posterior access route. In the third case, retroperitoneal access via the anterior route meant that the technique could be performed in one stage, resulting in an overall reduction in surgical time (1250 vs. 1750 vs. 990 minutes, respectively). Conclusion: The new technique enables fixation with biomechanical stability, which is essential to support the stress in the lumbosacral transition and promote earlier rehabilitation.
