Introduction: There is currently an increasing use of biological agents in the management of Crohn's disease (CD). There is lack of data regarding the epidemiological profile of patients on infliximab (IFX) and adalimumab (ADA) for CD in Brazil. Objective: To identify the epidemiological characteristics of patients with CD who underwent biological therapy. Method: Retrospective multicenter study, with CD patients on biological therapy. Analyzed variables: gender, age at treatment initiation, Montreal classification, concomitant perianal disease and smoking status. Results: 175 patients without previous exposure to biological agents were included, 93 (53%) were male. The mean age at treatment initiation was 35.5 (2-79) years old an the mean disease duration was 46.9 (0-480) months. Overall, 117 (66.9%) patients used IFX and 58 (33.1%), ADA. Montreal classification: age at diagnosis-A1 (n=21; 12%), A2 (n=102; 58.3%), and A3 (n=52; 29.7%). CD location-L1 (n=42; 24%), L2 (n=51; 29.1%), L3 (n=81; 46.3%), and L4 (n=1, 0.6%). Phenotype-B1 (n=59; 33.7%), B2 (n=46; 26.3%), and B3 (n=70; 40%). Perianal disease was found in 89 (50.9%) patients. Conclusions: The epidemiological profile of patients was similar to the literature. There was a high prevalence of patients with fistulizing CD.

RESUMOObjetivo: O objetivo do estudo é descrever as características epidemiológicas dos pacientes portadores de afecções nos sesamoides em uma amostra de pacientes do SUS. Métodos: Estudo retrospectivo realizado através da revisão de prontuário eletrônico dos atendimentos ambulatoriais de pé e tornozelo, nos últimos 5 anos, analisando as variáveis como sexo, idade, profissão, raça, prática esportiva, lateralidade e identificação do sesamoide acometido (medial ou lateral). Resultados: As anormalidades relacionadas aos sesamoides do hálux ocorrem com maior frequência no sexo feminino (63/108), na 3 a década de vida (56/108), mais comumente no sesamoide medial (74/108), e estão relacionadas a 65,7% de praticantes de atividade física regular, sem relação significativa com a lateralidade ou a profissão. Conclusão: O sexo mais acometido foi o feminino, com média de idade de 23,7 anos, sendo mais comum no lado direito, no osso medial, em praticantes de atividade física frequente.

ABSTRACTObjective: The objective of this study is to describe the epidemiological characteristics of patients with sesamoid disorders in a sample of patients treated in the Brazilian public health system. Methods: A retrospective study was performed by reviewing the electronic charts of foot and ankle outpatient consultations over the past 5 years, analysing variables such as sex, age, occupation, ethnicity, participation in sports, laterality, and affected sesamoid (medial or lateral). Results: Abnormalities in hallucal sesamoids occur more frequently in women (63/108), during the third decade of life (56/108), and in the medial sesamoid (74/108); 65.7% of the sample with these abnormalities participated in physical activity regularly. No significant relationship was observed with laterality or occupation. Conclusion:The most commonly affected patients were females, with a mean age of 23.7 years, who participated in physical activity frequently; the right side and medial sesamoid bone were the most commonly affected sites.

Objective: To determine the prevalence of short gastrocnemius in orthopaedic patients treated in the emergency room and the foot and ankle outpatient clinic of a public hospital and to evaluate the relationship between prevalence and certain specific symptoms. Methods: This was an observational cross-sectional study conducted using a questionnaire completed by patients treated in February 2018. Results: Of the 160 patients studied, 21 (13.1%) had a diagnosis of shortening of the gastrocnemius. The condition was more prevalent in females than in males, with no differences in race, age, laterality or occupation. The most commonly associated symptoms were calf pain, back pain, equinism and metatarsalgia, which were all present in more than 2/3 of cases. Conclusion: Shortening of the gastrocnemius is a fairly common pathology that deserves greater attention in orthopaedic practice. Additional studies are needed to better correlate epidemiological findings with this pathology. Level of Evidence II; Diagnostics Studies.

Introduction: The sesamoid bones are part of the hallux metatarsophalangeal (MTTF) joint complex and are an important factor in the normal biomechanics of gait. Abnormalities of the sesamoid bones are not rare but are often underestimated and include acute fractures, osteochondral lesions, bipartite sesamoids, recurrent traumatic sesamoiditis or infection, in addition to osteoarthritis. Given the lack of recent studies on the epidemiological profile of sesamoid-related diseases, the objective of this study is to identify the epidemiological characteristics of patients with these disorders. Methods: The study was approved by the research ethics committee and registered in the Brazil Platform (Plataforma Brazil). This retrospective study was performed by reviewing the electronic charts of foot and ankle outpatients diagnosed with sesamoiditis and acute or stress fractures between February 1, 2013 and January 31, 2018. The exclusion criterion used was the presence of incomplete records in the electronic chart. The following variables were analyzed: sex, age, occupation, participation in sports, laterality and affected sesamoid bone (medial or lateral). The data collected were tabulated and saved in an Excel spreadsheet and analyzed using descriptive statistics. Results: Data on 108 patients were collected after reviewing the charts. Based on these data, we report the epidemiological characteristics of patients with sesamoid disorders in a sample of orthopedic patients from a reference hospital of the Unified Health System (Sistema Único de Saúde – SUS) in a city in southern Brazil. Among the various occupations reported, the 3 most common were cleaner (29), student (23) and salesperson (16). Among the subjects who participated in sports, only 22 were involved in competitive sports (professional or amateur).
