- BILATERAL LOCALIZED PIGMENTED VILLONODULAR SYNOVITIS OF THE KNEE: CASE REPORT AND REVIEW(2018) FERNANDES, Tiago Lazzaretti; VIDEIRA, Livia Dau; SASAKI, Sandra Umeda; NATALINO, Renato Jose Mendonca; ALMEIDA, Adriano Marques de; PEDRINELLI, Andre; HERNANDEZ, Arnaldo JoseObjectives: Several cases of bilateral diffuse pigmented villonodular synovitis (PVNS) or tenosynovial giant cell tumor have been described in the literature. Nevertheless, some presentations are rare and differential diagnoses are necessary. Methods: The purpose of this study was to perform a systematic review of the literature related to PVNS and to report a rare supra-patellar bilateral and focal presentation. We performed a systematic data review in the Pubmed Clinical Queries database using MeSH and keywords related to PVNS and tenosynovial giant cell tumor. Results: Two cases of bilateral and local PVNS had been previously described, but neither was localized in the supra-patellar compartment. To our knowledge, this case report is the first to describe supra-patellar bilateral and localized PVNS of the knee. This case involves a 28-year-old woman with bilateral localized PVNS of the supra-patellar recess of the knee. MRI showed a low-signal intensity nodule in T1-and T2-weighted images. These were associated with hemosiderin pigmentation. Conclusion: The most important finding of the case reported is related to rarity and location. Histopathology analysis confirmed a rare case of hemosiderin pigmentation in the capsular nodule with internal non-pigmented villous content. Lipoma arborescens in the supra-patellar form must be ruled out as a differential diagnosis since it occurs in the same site.
- ANALYSIS OF MEDICAL ASSISTANCE PROVIDED TO SPECTATORS AT THE 2014 FIFA WORLD CUP MATCHES(2018) ARLIANI, Gustavo Goncalves; LARA, Paulo Henrique Schmidt; PEDRINELLI, Andre; EJNISMAN, Benno; LEITE, Luiz Marcelo Bastos; COHEN, MoisesObjective: Several studies have already described the main injuries to soccer players during FIFA World Cup events; however, little is known about the main reasons spectators require medical assistance during these matches. The aim of this study is to assess the number of cases and main reasons spectators required medical assistance during the 2014 World Cup matches in Brazil. Methods: Data were collected from spectators who received medical assistance on all game days, and factors related to the assistance provided were analyzed. Results: Medical assistance was given to spectators in a total of 6,222 cases during the 64 games played in Brazil, an average of 97.2 times per game. The total number of spectators removed from the stadiums by ambulance was 167, a mean of 2.6 removals per game. The main reasons spectators required medical assistance during the World Cup games were headache, gastrointestinal problems, and trauma. Conclusions: Most spectators required medical assistance during the World Cup games for headache, gastrointestinal problems, and trauma; this information is fundamental to develop new prevention strategies and plan medical assistance for large-scale events.
- Determination of cervical stenosis in rugby players using an alternative radiographic method(2018) BORNHOLDT, Gustavo C.; LOPES, Bruno Siqueira Campos; PAZ, Pedro Francisco Senne; HERNANDEZ, Arnaldo Jose; PEDRINELLI, AndrePurpose To find a radiographic method that best correlates with the mean subaxial cervical space available for the cord (MSCSAC) by using a fixed size parameter as radiographic reference, in contrast to the use of vertebral bodies as reference in the mean subaxial cervical Torg ratio (MTorg). Methods The study was approved by an institutional review board and written informed consent was obtained. Radiographs and cervical neck MRI were obtained from 18 male rugby athletes (age 18-30 years). Rheumatic disease, symptomatic cervical orthopaedic disease and previous cervical injury were used as exclusion criteria. MSCSAC and MTorg were calculated for each individual as the space available for the cord and Torg ratio averages from C3 to C6, respectively. A new radiographic method, using a metal bar as a size parameter (the corrected diameter of the cervical canal - CDCC), was also calculated for each individual, as well as its average from C3 to C6 (mean corrected diameter of the cervical canal - MCDCC). Values obtained for MCDCC and MTorg were correlated with those obtained by the MSCSAC using Pearson's coefficient. Results Four volunteers were excluded due to previous cervical injury. In total, 14 subjects had their radiographs and MRIs analysed. Pearson's correlation between MSCSAC and MTorg was 0.5706 (p=0.033). The correlation between MSCSAC and MCDCC was 0.6903 (p=0.006). Conclusion MCDCC correlates better than MTorg with MSCSAC and may be a better radiographic option than MTorg for cervical stenosis evaluation.
- Quality assessment of muscle injury classification in sports: a systematic literature review(2018) SANTANNA, Joao Paulo C.; ALMEIDA, Adriano M. de; PEDRINELLI, Andre; HERNANDEZ, Arnaldo J.; FERNANDES, Tiago L.Introduction: Muscular injuries are very common and lesion categorization is important for patient treatment and orientation. There is no study in literature that assessed methodological quality of classifications for muscle injury in sports. The objective of this study was to evaluate the quality of manuscripts that proposed a classification of muscular injury in sports. Methods: A systematic search for articles in English, Spanish and Portuguese languages containing terms related to ""muscle, skeletal/injuries"", ""athletic injuries"", ""classification"", ""diagnosis"" and ""etiology"" were carried out. Articles included for evaluation proposed classifications of muscular injuries related to sports and were submitted to methodological quality appraisal from Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) protocol. Results: 1606 articles were found. From those, 17 proposed an organized system with different sorts of muscular injury. The 17 studies were graded according to methodological quality, considering risk of bias and applicability of each classification. Three studies presented very good results and one showed good results. The remaining articles presented a high or undetermined risk of bias and problems related to applicability. Conclusion: There is a wide variety of methodological quality of classification studies. Most classifications system are only a theoretical model and therefore have important limitations.
- Aerobic fitness in professional soccer players after anterior cruciate ligament reconstruction(2018) ALMEIDA, Adriano Marques de; SILVA, Paulo Roberto Santos; PEDRINELLI, Andre; HERNANDEZ, Arnaldo J.Although anterior cruciate ligament (ACL) reconstruction is considered a successful procedure in restoring knee stability, few studies have addressed the issue of aerobic capacity after ACL surgery. Soccer players need technical, tactical and physical skills to succeed, such as good knee function and aerobic capacity. Our purpose is to evaluate aerobic fitness in ACL injured professional football players and six months after ACL reconstruction compared to a control group. Twenty athletes with ACL injury were evaluated and underwent ACL reconstruction with hamstrings autograft, and were compared to twenty healthy professional soccer players. The methods used to evaluate aerobic fitness were maximum oxygen uptake (VO2max) and ventilatory thresholds with a treadmill protocol, before and six months after surgery, compared to a control group. Knee function questionnaires, isokinetic strength testing and body composition evaluation were also performed. Results: Median ACL-injured patients age was 21 years old, and controls 20.5 years old. (n.s.). Preoperative VO2max in the ACL injured group was 45.2 +/- 4.3 mL/kg/min, postoperative 48.9 +/- 3.8 mL/kg/min and controls 56.9 +/- 4.2 mL/kg/min. (p<.001 in all comparisons). Body composition evaluation was similar in all situations. Knee function questionnaires and quadriceps peak torque deficit improved after surgery but were significantly lower compared to controls. Conclusion: Aerobic fitness is significantly reduced in professional soccer players with ACL injury, and six months of rehabilitation was not enough to restore aerobic function after ACL reconstruction, compared to non-injured players of the same level.
- MENISCAL REPAIR RESULTS COMPARING MRI, ARTHRO-MRI, AND ARTHRO-CT(2018) ALMEIDA, Adriano Marques de; RODRIGUES, Marcelo Bordalo; REZENDE, Marcia Uchoa de; PEDRINELLI, Andre; HERNANDEZ, Arnaldo JoseObjective: To clinically and radiologically evaluate patients who received meniscal suture using the outside-in technique, comparing magnetic resonance imaging (MRI), arthro-magnetic resonance imaging (arthro-MRI), and arthro-computed tomography (arthro-CT) to evaluate the healing of meniscal sutures. Methods: We evaluated eight patients with an average follow-up of 15 months. The evaluation analyzed clinical parameters using the Lysholm and IKDC scores as well as MRI, arthro-MRI, and arthro-CT imaging. Results: At the end of the follow-up period, mean Lysholm score was 89.5 and mean IKDC score was 78.6. In the MRI, signs of meniscal healing were observed in 50% of the cases. The arthro-MRI and arthro-CT showed signs of healing in 75% of cases. There was a positive correlation between arthro-MRI and arthro-CT results in all the cases studied (kappa correlation index=1). Conclusion: Meniscal suture using the outside-in technique presented good or excellent results in 87.5% of our patients. The arthro-CT and arthro-MRI showed the same level of accuracy in detecting healing of the sutured region of the meniscus.
