RESUMO
Objective: To understand the Adverse Analytical Finding (AAF) that have occurred in Brazilian soccer in a recent 10-year period, comparing them to international data, to know the Brazilian profile. Methods: A review of the AAR in the Doping Control Commission database of the Brazilian Football Association from 2008 to 2017. The AAR in professional male soccer players between 2008 and 2017 were considered. Results: The sample selected in this research was composed of 40,092 doping tests, with 113 AAR, identified in 18 different competitions (0.28%) in the professional category, in Brazilian national and state competitions between 2008 and 2017, flagged in doping control exams through urine samples. Stimulants were detected most frequently (31.0%), followed by glucocorticoids (21.2%), diuretics, and masking agents (19.5%). The Brazilian Championship series did not show a relationship with any of the World Anti-Doping Agency (WADA) groups of substances. Series A showed 0.07% of AAR, Series B 0.21%, Series C 0.75% and Series D 1.49. Conclusion: The rate of AAR in Brazilian soccer was 0.28%, lower than the average for all soccer worldwide, and shows similar percentages among field positions. Stimulants were the most prevalent drugs. The national elite soccer competitions showed significantly fewer cases than the lower divisions. Level of Evidence II; Retrospective Study.

RESUMO
OBJECTIVES: Football is a globally played sport that poses potential risks for musculoskeletal injuries. Upper-limb injuries have a lower incidence rate than lower-limb injuries but can still cause absenteeism and performance impairment in football players. This descriptive epidemiological study aimed to evaluate and compare the epidemiological data on shoulder injuries among professional football players in two major Brazilian football championships. METHODS: Data were collected throughout the championships, and club physicians medically evaluated each player during official games using two online forms. The collected information included the player's age and position, injury diagnosis, laterality, location on the field where the injury occurred, playing time, imaging examinations performed, need for surgical treatment, time to return to play (TRP), and recurrence of the injury. The incidence of injuries was evaluated using the Federation Internationale de Football Association (FIFA) incidence formula. RESULTS: A total of 107 shoulder injuries were recorded (4.3% of all injuries), with a FIFA incidence of 0.847. Glenohumeral dislocations (GHDs) and acromioclavicular dislocations (ACDs) accounted for 37.38% and 35.51% of all shoulder injuries, respectively. Goalkeepers and defenders presented, respectively, a 2.15 and 1.57 times increased risk of suffering shoulder injuries, while attackers presented a 0.63 times decreased risk. Injury recurrence was observed in 14.95% of cases, with GHDs and ACDs showing recurrence rates of 35.00% and 5.26%, respectively. Surgery was performed in 9.35% of cases, with GHDs representing 50% of all surgeries. The average TRP was 22.37 days, with severe and major injuries accounting for 11.21% and 10.28% of all injuries, respectively. Goalkeepers had the highest average TRP of 36.15 days. Recurring injuries had a higher average TRP of 33.44 days compared to nonrecurring injuries, which had an average TRP of 20.43 days. Surgically treated injuries had the highest average TRP of 112.5 days. CONCLUSION: Shoulder injuries in the professional football scenario are of great concern due to the high recurrence rate and need for surgical treatment, which will lead to a long TRP. These findings emphasize the need to implement prevention protocols and effective treatments to reduce the consequences of such injuries, which are usually underestimated in this sport. LEVEL OF EVIDENCE: III.

RESUMO
Introduction Dorsal root entry zone (DREZ) leasioning (DREZ-otomy) is considered an effective treatment for chronic pain due to spinal cord injuries, brachial and lumbosacral plexus injuries, postherpetic neuralgia, spasticity, and other conditions. The objective of the technique is to cause a selective destruction of the afferent pain fibers located in the dorsal region of the spinal cord. Objective To identify and review the effectiveness and the main aspects related to DREZ-otomy, as well as the etiologies that can be treated with it. Methods The PubMed, MEDLINE and LILACS databases were used as bases for this systematic review, having the impact factor as the selection criteria. The 23 selected publications, totalizing 1,099 patients, were organized in a table for systematic analysis. Results Satisfactory pain control was observed in 70.1% of the cases, with the best results being found in patients with brachial/lumbosacral plexus injury (70.8%) and the worst, in patients with trigeminal pain (40% to 67%). Discussion Most of the published articles observed excellent results in the control of chronic pain, especially in cases of plexus injuries. Complications are rare, and can be minimized with the use of new technologies for intraoperative monitoring and imaging. Conclusion DREZ-otomy can be considered a great alternative for the treatment of chronic pain, especially in patients who do not tolerate the side effects of the medications used in the clinical management or have refractory pain.

RESUMO
OBJECTIVE: To evaluate and collect epidemiological data on injuries of the anterior cruciate ligament of the knee in professional soccer players of the Brazilian Championship. METHODS: Transversal study, with information extracted from the online data platform www.transfermrkt.com.br (Transfermarkt GmbH & Co. KG), with 5 seasons (2015 - 2019) of the Brazilian championship series A and B being analyzed and revised by 3 researchers. RESULTS: 52 injuries of the anterior cruciate ligament were detected, with a mean age of 26,3 years, time off due to injury of 244.5 ±31.6 days, regardless of the division. Forwarders and defenders had the highest incidences of injury without statistically significant difference, but they had greater chances than goalkeepers, left/right backs and midfielders. CONCLUSION: The incidence of injury to the anterior cruciate ligament of the knee in professional football players in the first and second divisions of the Brazilian soccer championship between 2015 and 2019 is 0.414 per 1,000 hours of play, a value similar to described in the literature. The incidence of the injury varies according to the player's field position, being the forwarders and defenders the most injured players. Level of Evidence II, Retrospective study.
OBJETIVO: Avaliar dados epidemiológicos das lesões do ligamento cruzado anterior do joelho em jogadores profissionais de futebol do Campeonato Brasileiro. MÉTODOS: Estudo transversal, com informações extraídas da plataforma de dados on-line www.transfermrkt.com.br (Transfermarkt GmbH & Co. KG), sendo analisadas 5 temporadas (2015 - 2019) do campeonato brasileiro séries A e B por 3 pesquisadores. RESULTADOS: Detectamos 52 lesões do ligamento cruzado anterior, com idade média de 26,3 anos, tempo de afastamento devido a lesão de 244,5 +- 31,6 dias, independentemente da série. Atacantes e zagueiros apresentaram maiores incidências de lesão sem diferença estatisticamente significante entre eles, porém apresentaram maiores chances que goleiros, laterais e meio campistas. CONCLUSÃO: A incidência da lesão do ligamento cruzado anterior do joelho em atletas de futebol do campeonato brasileiro série A e B entre 2015-2019 é de 0,414 por 1.000 horas de jogo, semelhante ao descrito em literatura. A incidência da lesão depende da posição tática do jogador, com atacantes e zagueiros sofrendo mais lesões em relação as outras posições. Nível de Evidência II, Estudo retrospectivo.
RESUMO
BACKGROUND: The treatment of neuropathic pain (NP) continues to be controversial as well as an economic health issue and a challenge to health care. Neurosurgery can offer different methods of neuromodulation that may improve patients' condition, including deep brain stimulation (DBS), motor cortex stimulation (MCS), spinal cord stimulation (SCS), and posterior insula stimulation (PIS). There is no consensus of opinion as to the final effects of these procedures, which stimulation parameters to select, the correct timing, or how to select the patients who will best benefit from these procedures. OBJECTIVE: To review the evidence available regarding these 4 procedures and the management of NP. METHODS: We conducted a PubMed, Embase, and Cochrane Library database search from 1990 to 2020. The strategy of the search concentrated on the following keywords: "neuropathic pain," "chronic pain," "deep brain stimulation," "motor cortex stimulation," "spinal cord stimulation," "insula stimulation," and "neuromodulation." Studies that provided data regarding the immediate and long-term effectiveness of the procedure, anatomic stimulation target, percentage of pain control, and cause of the NP were included. RESULTS: The most frequent causes of NP were phantom limb pain and central poststroke pain in the MCS group; central poststroke pain, phantom limb pain, and spinal cord injury (SCI) in the DBS group; and complex regional pain syndrome and failed back surgery syndrome in the SCS group. Pain improvement varied between 35% and 80% in the MCS group and 50% and 60% in the DBS group. In the SCS group, successful rates varied between 38% and 89%. CONCLUSIONS: This systematic review highlights the literature supporting SCS, DBS, MCS, and PIS methods for the treatment of NP. We found consistent evidence supporting MCS, DBS, and SCS as possible treatments for NP; however, we were not able to define which procedure should be indicated for each cause. Furthermore, we did not find enough evidence to justify the routine use of PIS. We conclude that unanswered points need to be discussed in this controversial field and emphasize that new research must be developed to treat patients with NP, to improve their quality of life.

Objective To perform a prospective evaluation of muscle injuries that occurred during the matches of series A and B of the Brazilian Men's Football Championship from 2016 to 2018. Prospective A prospective-cohort study with data collection regarding muscle injuries that occurred during the official matches of the first and second divisions of the Brazilian Men's Soccer Championship in the 2016, 2017 and 2018 seasons. Results The total number of muscle injuries was of 577 throughout the 3 seasons, with a gradual and annual reduction in the incidence of injuries (219 injuries in 2016, 195 in 2017, and 163 in 2018), with a statistically significant difference between the 2016 and 2018 seasons. Muscle injuries represented approximately 35% of the total lesions. The incidence of muscle injuries was of 7.66 per 1,000 hours of play. During the 3 seasons (2016 to 2018), the most common injury was of the hamstring muscle (41.1%, 40.5%, and 33.7% respectively). Wingers were the most affected players, and the most common injury severity scale was moderate (8 to 28 days). The moment of the match with the highest incidence of injuries was in the period between 61 and 75 minutes, with an index of 19.9%, with no statistical difference in relation to the other periods of the match. Conclusion There was an incidence of muscle injuries of 7.7 /1,000 h, and they occurred predominantly in home games, in defenders (wingers and centre-backs), with an average age of 28 years, mainly involving the hamstring muscles, with a moderate mean time of absence (8 to 28 days).

External defenders suffered most injuries, while muscular injuries were most common and lower limbs, the most affected areas. Most injuries occurred between 30 and 45 minutes of the match and only 11.9% of the injuries required surgery. Conclusions: Prevalence and frequency of injuries decreased between seasons. Most injuries were sustained in the lower limbs; strains were the most common injuries, followed by strains and contusions; MRIs were the most frequently requested exams and most injuries were classified as moderate (8-28 days). Level of evidence III, Cross-Sectional Study.
RESUMO Objetivo: Comparar a incidência e características das lesões ocorridas em duas temporadas consecutivas no campeonato Paulista de Futebol. Métodos: Realizamos um estudo prospectivo, através de questionário eletrônico previamente desenvolvido pelo Comitê Médico da Federação Paulista de Futebol e enviado aos médicos dos times das séries A1 e A2 do Campeonato Paulista de Futebol após cada rodada. Resultados: A série A1 apresentou 17,63 lesões por 1000 horas de jogo e a série A2 14,91 lesões por 1000 horas de jogo. A incidência de lesões por 1000h de jogo caiu de 24,16 para 17,63 na serie A1 (p<0,037) e de 19,10 para 14,01 na serie A2 (p<0,064). Os laterais foram os mais acometidos, as lesões musculares as mais frequentes e os membros inferiores os mais acometidos. A maioria das lesões ocorreu entre 30 e 45 minutos de jogo e somente 11,9% das lesões necessitaram de cirurgia. Conclusão: Houve uma queda da prevalência e da incidência de lesões entre as temporadas. A maioria das lesões ocorreu nos membros inferiores, o tipo mais comum de lesão foi o estiramento, seguido de entorse e contusão, o exame mais pedido foi a ressonância magnética e a maioria das lesões foi classificada como moderada (8-28 dias).

RESUMO
OBJECTIVE: To identify the incidence of injuries, their main characteristics, and the way they were managed throughout 2016 in two major series of a professional soccer championship in São Paulo, Brazil. METHODS: This prospective study used an electronic questionnaire previously developed by the Medical Committee of the Paulista Soccer Federation which was sent to the team doctors after each match. RESULTS: Two hundred and fifty-nine injuries occurred during 361 matches, and the incidence of injury per 1000 hours of game play was 21.32. Strikers were the most affected by injury; the most frequent diagnosis was muscle injury and the legs were predominantly affected. Most of the injuries occurred in the last 15 minutes of the first half and only 7.7% required surgical treatment. CONCLUSIONS: Muscle injuries were the most frequent, with most occurring in forwards and in the legs. Approximately half of the injuries occurred after contact and the vast majority was treated without surgery. MRI was the most requested exam and most injuries were classified as moderate (8 to 28 lost play days). Level of Evidence III, Study of Non Consecutive Patients; Without Consistently Applied Reference "Gold" Standard.
OBJETIVO: Identificar a incidência de lesões, suas principais características e a maneira como foram conduzidas durante todo o ano de 2016 nas duas principais séries (A1 e A2) do Campeonato Paulista. MÉTODOS: Realizou-se um estudo prospectivo por meio de questionário eletrônico previamente desenvolvido pelo Comitê Médico da Federação Paulista de Futebol, que foi enviado aos médicos dos times das séries A1 e A2 do Campeonato Paulista de Futebol após cada rodada. RESULTADOS: Houve 259 lesões durante 361 jogos, com incidência de 21,32 lesões por 1.000 horas de jogo ao se agrupar as duas séries do Campeonato Paulista. Os atacantes foram os mais envolvidos, sendo as lesões musculares as mais frequentes e os membros inferiores os mais afetados. A maioria das lesões ocorreu nos últimos 15 minutos do primeiro tempo e somente 7,7% das lesões precisaram de tratamento cirúrgico. CONCLUSÕES: As lesões musculares são as mais frequentes, sendo que a maioria ocorreu em atacantes e nos membros inferiores. Cerca de metade das lesões ocorreu após contato e a maioria absoluta das lesões foi tratada de forma não cirúrgica. A ressonância magnética foi o exame mais solicitado e a maior parte das lesões foi classificada como de gravidade moderada (8 a 28 dias de afastamento).

RESUMO
BACKGROUND: Football is a high-speed contact sport and the risk of injury is high. The objective of this study was to compare the two main divisions (A1 and A2) of the São Paulo Football Championship and to perform a correlation analysis of the variables studied. METHODS: A prospective study was conducted using an electronic questionnaire previously developed by the Medical Committee of the São Paulo Football Federation. The questionnaire was sent to the doctors of the teams playing in the A1 and A2 divisions of the São Paulo Football Championship after each round. Setting: 2016 São Paulo Football Championship. RESULTS: The comparison of divisions A1 and A2 showed few significant differences among the various variables analysed in this study. The only significant differences were for right-side involvement in division A1 (p=0.044) and morning matches in division A2 (p<0.001). The correlation analysis of the variables studied showed expected associations, including sprains with a higher rate of need for surgery, ultrasound with muscle strains and moderate severity (8-28 days lost) with muscle strains. CONCLUSION: Despite the differences between the two divisions regarding budgets and team characteristics, there was a little difference in the variables analysed and there were associations such as sprains with a higher rate of need for surgery, ultrasound with muscle strains and moderate severity (8-28 days lost) with muscle strains. LEVEL OF EVIDENCE: II b, individual cohort study.
RESUMO
OBJECTIVE: To establish the method of isolation and culture of human glioblastoma neurospheres, and the purification of their stem cells, followed by the process of obtaining tumor subspheres, immunophenotypically characterizing this clonogenic set. METHODS: Through the processing of glioblastoma samples (n=3), the following strategy of action was adopted: (i) establish primary culture of glioblastoma; (ii) isolation and culture of tumor neurospheres; (iii) purify cells that initiate tumors (CD133+) by magnetic separation system (MACS); (iv) obtain tumor subspheres; (v) study the expression of the markers nestin, CD133, and GFAP. RESULTS: The study successfully described the process of isolation and culture of glioblastoma subspheres, which consist of a number of clonogenic cells immunophenotypically characterized as neural, which are able to initiate tumor formation. CONCLUSION: These findings may contribute to a better understanding of the process of gliomagenesis.
