Changes in the methodology of medical teaching due to the COVID-19 pandemic

ABSTRACT Objective To evaluate the perceptions of students and teachers regarding remote teaching modality in comparison with the traditional face-to-face method. Methods In this observational, retrospective, comparative, single-center study, questionnaires containing three major assessment domains were sent to two groups: university professors and undergraduate and graduate students. The first domain collected demographic and general data on the platforms used. The second and third domains contained questions that compared the perception of the quality of information offered by the two systems. Results Between May and September 2020, 162 students and 71 teachers participated in the study. A greater proportion of students demonstrated previous contact with the online method, while professors had presented a greater number of courses. Most participants reported that their expectations regarding the remote teaching method were met (students, 80.3%; teachers, 94.4%). A significant number of students (83.3%) and teachers (88.7%) rated the classes as easier to attend and manage. Despite difficulties, such as concentration retention, most of the participants agree (at least partially) that the format should be maintained. Conclusion The remote teaching methodology, although still incipient in Brazil, has become a reality in light of current health restrictions. Our study demonstrated a high level of overall satisfaction and a high sense of learning from both students and faculty. However, new challenges associated with this system have been identified, such as retention of attention and interference from the external environment. Longitudinal comparative studies that incorporate various aspects of medical education in all cycles are necessary to corroborate the findings of this study. Design Retrospective comparative study, level III evidence.

Epiphysiolysis in a 22-year-old Patient with Congenital Hypogonadotropic Hypogonadism: Case Report / Epifisiólise em paciente de 22 anos de idade com hipogonadismo hipogonadotrópico congênito: Relato de caso

Abstract Epiphysiolysis is a relatively common disease in the adolescent population (9-16 years); however, it is rare in the adult population. It is characterized by non-traumatic proximal femur slipping. When it occurs in this population it is associated with some disease that slows sexual development and physis closure, such as endocrine diseases or brain tumors. The aim of the present study is to report a case of epiphysiolysis in a 22-year-old patient with hypogonadotropic hypogonadism. There are only 63 cases reported in the world literature on epiphysiolysis in the adult population.

Resumo A epifisiólise é uma doença relativamente comum na população adolescente (de 9-16 anos), entretanto rara na população adulta. Se caracteriza pelo escorregamento metáfiso-epifisário do fêmur proximal não-traumático. Quando ocorre nessa população, está associada a alguma doença que retarda o desenvolvimento sexual e fechamento fisário, como doenças endocrinológicas ou tumores cerebrais. O objetivo do presente estudo é relatar um caso de epifisiólise numa paciente com 22 anos de idade e hipogonadismo hipogonadotrófico. Existem apenas 63 casos relatados na literatura mundial sobre epifisiólise na população adulta.

The intra-articular use of an hemostatic and non-adherent bicomponent for pain control, hemarthrosis, and knee range of motion after anterior cruciate ligament reconstruction

Introduction: Complications in the recent postoperative period of anterior cruciate ligament reconstruction are common. Among them, pain, hemarthrosis, and difficulty of complete range of motion. The purpose of this study is to evaluate the use of the intra-articular carboxymethylcellulose ­ polysaccharide B bicomponent shortly after anterior cruciate ligament reconstruction, and to compare the results obtained for pain control, hemarthrosis, and knee range of motion with a control group. Materials and methods: randomized, and prospective clinical trial of thirty-two patients divided into two groups: reconstruction of the anterior cruciate ligament with an intra-articular injection of a bicomponent carboxymethylcellulose-polysaccharide B (n = 16) and without the bicomponent (n = 16). Pain, hemarthrosis and knee range of motion were evaluated in the first postoperative week. Results: the group with bicomponent presented less pain on the third (p = 0.017) and fifth (p = 0.029) postoperative day when compared to the control group. Hemarthrosis was significantly lower on the first postoperative day (p = 0.001), and there was a significant improvement in the range of motion on the seventh day of surgery (p = 0.008) in this same group. Conclusions: the use of intra-articular carboxymethylcellulose-polysaccharide B showed superior results for pain control, hemarthrosis, and gain in the knee range of motion in the recent postoperative period (up to seven days) after anterior cruciate ligament reconstruction, when compared to patients from the control group

The 50 most cited articles in the brazilian medical literature on knee surgery / Os 50 artigos mais citados da literatura médica brasileira sobre cirurgia do joelho

ABSTRACT Objective: To provide an analysis of the 50 most cited articles on knee surgery in the Brazilian medical literature. Methods: This is a study of systematic review and meta-analysis, level of evidence 3. It was carried out through search in the SCOPUS database to identify scientific articles published in the Brazilian medical literature. Eighty-six Brazilian journals were analyzed, and articles with ten or more citations and which had the word "joelho" or "knee" in the title, abstract or keywords were selected. Results: All articles were published as of the year 2000 in 14 journals. The Journal Clinics presented the largest number of publications, followed by Acta Ortopédica Brasileira. The main focus of the studies was on anatomy and biomechanics, mainly from Brazilian authors. Most of the authors were Brazilian, from Brazilian and public research institutions. Conclusion: Biometric analysis has been gaining ground in recent years, but its interpretation must consider various aspects related to the paramount analytical importance.

RESUMO Objetivo: Fornecer uma análise dos cinquenta artigos mais citados sobre cirurgia do joelho na literatura médica brasileira. Métodos: Foi utilizada a base de dados da SCOPUS para identificar artigos científicos publicados na literatura médica brasileira de 1945 a junho de 2008 com o tema referente ao joelho. Foram analisados 86 periódicos brasileiros e selecionados os artigos com número de citações igual ou superior a dez que possuíam a palavra "joelho" ou knee no título, resumo ou palavras-chave. Foram selecionados aqueles que possuíam a articulação do joelho como foco principal do estudo, chegando ao resultado final de cinquenta artigos mais citados. Resultados: Todos os artigos foram publicados a partir do ano 2000, em quatorze revistas. A Revista Clinics apresentou maior número de publicações, seguida da Acta Ortopédica Brasileira. A maior parte foi sobre estudos sobre anatomia e biomecânica, preponderamente de autores brasileiros. Instituições de pesquisa brasileiras e públicas foram as responsáveis pela maior parte das pesquisas. Conclusão: Análise biométrica vem ganhando espaço nos últimos anos, contudo sua interpretação deve considerar variados aspectos relacionados a importância analítica.

Functional Evaluation after Medial Patellofemoral Ligament Reconstruction in Athletes / Avaliação funcional da reconstrução do ligamento patelofemoral medial em atletas

Abstract Objective The aim of the present study was to evaluate the clinical results, functional outcomes, and risk factors after anatomic reconstructions using knee flexor grafts in athletes. Methods The authors followed-up 32 patients and 34 knees for 1 year in a prospective design case series evaluating pre- and postoperative functional scores (Kujala and Lysholm) and associated risk factors. Results All of the 32 patients had a significant increase of the Lysholm and Kujala scores. Patients with < 5 preoperative dislocations had a better score on the Lysholm and Kujala scales. The mean preoperative Lysholm score was 62.8, and the mean postoperative score was 94.3. The mean preoperative Kujala score was 63.0, and the mean postoperative score was 94.0. Conclusion Medial patellofemoral ligament reconstruction with hamstring graft in athletes with patellar instability improved clinical and functional scores. The bone drilling through the patella and the positioning of the femoral tunnel should be judiciously performed.

Resumo Objetivo Avaliar os resultados clínicos e funcionais da reconstrução anatômica do ligamento patelofemoral medial com tendões flexores em atletas. Métodos Estudo tipo série de casos, prospectivo, que analisou a reconstrução do ligamento patelofemoralmedial em32 pacientes (34 joelhos). A avaliação funcional foi feita pelos escores Lysholm e Kujala nos períodos pré e pós-operatórios e os fatores de risco envolvidos foram avaliados. Resultados Dos 32 pacientes analisados, todos obtiveram melhoria dos escores funcionais comparativamente ao período pré-operatório. Pacientes com menos de cinco episódios de luxação prévios obtiveram melhores resultados funcionais. O valor médio de Lysholm no pré-operatório foi de 62,8 e no pós-operatório de 94,3, quanto ao escore de Kujala a média pré-operatório foi de 63,0 e pós-operatória de 94,0. Conclusão A reconstrução do ligamento patelofemoral medial com enxerto de tendão flexor do joelho em atletas propiciou melhoria dos escores clínicos e funcionais nos pacientes com instabilidade patelofemoral. A perfuração óssea da patela e o posicionamento do túnel femoral devem ocorrer de forma judiciosa.

Ultrasonography for evaluation of hamstring tendon diameter: is it possible to predict the size of the graft? / Ultrassonografia para avaliação do diâmetro dos tendões flexores do joelho: é possível predizer o tamanho do enxerto?

ABSTRACT Objective: Perform the preoperative measurement of the hamstring tendons using ultrasound imaging, validating and correlating the measured value with that found during surgical reconstruction of the ligament. Methods: A cross-sectional study was carried out with 24 patients who underwent ultrasonographic measurement of the semitendinosus and gracilis muscle tendons and were subsequently submitted to surgical reconstruction of the ACL, with ipsilateral semitendinosus and gracilis tendon grafting. Results: The patients' ages ranged from 16 to 43 years, with a mean of 24.8 years (SD = 8.4 years), 79.2% were men, and the distribution by side was 41.7% right knees and 58.3% left knees. A non-significant correlation coefficient was found between the area calculated by ultrasound (2 × semitendinosus area + 2 × gracilis area) and the intraoperative measurement (r = 0.16; p = 0.443). No evidence of a difference between intraoperative measurements <8 mm and ≥8 mm was found for the area calculated by the ultrasound (p = 0.746). The difference observed between the groups was −0.01 (95% CI: −0.09 to 0.07). Conclusion: Preoperative ultrasound imaging of the semitendinosus and gracilis tendons does not present a statistically significant correlation with the intraoperative measurement of the quadruple hamstring graft for ligament reconstruction.

RESUMO Objetivo: Fazer a mensuração pré-operatória dos tendões flexores do joelho com o uso do exame de ultrassonografia, validar e correlacionar o valor medido com aquele encontrado durante a reconstrução cirúrgica do ligamento. Métodos: Estudo transversal com 24 pacientes submetidos a mensuração ultrassonográfica dos tendões dos músculos semitendíneo e grácil e posteriormente submetidos a reconstrução cirúrgica do LCA, com enxerto ipsilateral dos tendões semitendíneo e grácil do próprio paciente. Resultados: A idade dos pacientes variou entre 16 e 43 anos, com média de 24,8 (DP = 8,4), 79,2% eram homens e a distribuição quanto ao lado foi de 41,7% joelhos direitos e 58,3% joelhos esquerdos. Foi encontrado coeficiente de correlação não significante entre a área calculada a partir do ultrassom (2 × área do semitendíneo + 2 × área do grácil) e a medida obtida intraoperatoriamente (r = 0,16, p = 0,443). Não foi encontrada evidência de diferença entre medidas intraoperatórias < 8 mm e ≥ 8 mm quanto à área calculada a partir do ultrassom (p = 0,746). A diferença observada entre os grupos foi de -0,01 (IC 95%: -0,09 a 0,07). Conclusão: A mensuração pré-operatória por método de imagem ultrassonográfico dos tendões dos músculos semitendíneo e grácil não apresenta correlação estatisticamente significante com a mensuração intraoperatória do enxerto quádruplo de flexores para reconstrução ligamentar.

Common injuries in athletes' knee: experience of a specialized center

OBJECTIVE: The present cross-sectional study aims to identify the most common knee injuries in athletes cared at a Specialized Outpatient Clinics. METHOD: Analysis of patients cared at the Knee Outpatient Clinics of a Sports Trauma Center, divided by gender, age and diagnosed injury. RESULTS: Initially 440 patients were divided into 33 types of sports; after excluding the less statistically significant practices, nine sports remained. The most frequently performed sports were football with almost 50% of total patients presenting anterior cruciate ligament (ACL) injury, and road runs with great frequency of meniscal injury. There was no correlation of the disorder with the type of sports performed but a correlation was found with patient's age/gender. CONCLUSION: The complete ACL rupture was the most common injury found in football, basketball and volleyball players, followed by meniscal injury in street runners.

Tratamento das fraturas da diáfise dos ossos do antebraço em crianças e adolescentes / Treatment of forearm fractures in children and adolescents

OBJETIVO: O tratamento e os desvios angulares tolerados nas fraturas diafisárias do antebraço em crianças evoca opiniões divergentes na literatura. Frente a esta indefinição, idealizamos este trabalho com o objetivo de avaliar transversalmente os métodos terapêuticos preferenciais para esta lesão durante o 39º Congresso Brasileiro de Ortopedia e Traumatologia. MÉTODO: Foram respondidos 759 questionários (13 por cento do total de inscritos). Abordamos os aspectos gerais da amostra estudada para traçar o perfil do ortopedista questionado. Foram expostas duas situações clínicas em indivíduos de 12 (CASO 1) e 5 anos (CASO 2), sendo apresentadas radiografias com fraturas do antebraço destes pacientes. Os dados obtidos foram compilados e submetidos à análise estatística. RESULTADO: O tratamento mais indicado no CASO 1 foi redução incruenta e fixação com fios de Kirschner (26 por cento), enquanto no CASO 2 foi redução incruenta seguida de aparelho gessado (46 por cento). CONCLUSÃO: Entre os ortopedistas com menos de 30 anos, a escolha por tratamentos menos invasivos e aceitação de maiores angulações prevaleceu para ambos os casos. Os traumatologistas aceitam menor angulação e tendem aos tratamentos invasivos, particularmente para o CASO 2. Já o ortopedista pediátrico opta por tratamentos menos invasivos e aceita maiores desvios angulares.

OBJECTIVE: The treatment and the angular deviations tolerated in diaphyseal forearm fractures in children evoke divergent opinions in literature. In view of this controversy, we idealized this study to evaluate the preferred treatment methods for this injury, during the 39th Brazilian Congress on Orthopedics and Traumatology. METHODS: A total 759 questionnaires were answered (13 percent of total entrants). We addressed the general aspects of the study sample to obtain a profile of the orthopedic surgeons questioned. RESULTS: Two clinical subjects were presented, aged 12 (CASE 1) and 5 years old (CASE 2), along with radiographs depicting forearm diaphyseal fractures of these patients. Data was gathered and submitted to statistical analysis. The overall preferred treatment in CASE 1 was closed reduction and fixation with Kirschner wires (26 percent), while in case 2 it was closed reduction followed by plaster cast (46 percent). CONCLUSION: Among orthopedic surgeons less than 30 years old, the choice for less invasive treatments and greater acceptance of angular values prevailed in both cases. The traumatologists accepted lower angular values and tended towards more invasive treatments, particularly for CASE 2. On the other hand, the pediatric orthopedic surgeon prefers less invasive treatments and accepts greater angular deviations.
