RESUMO
Bone lesions have the capacity for regeneration under normal conditions of the bone metabolism process. However, due to the increasing incidence of major traumas and diseases that cause bone-mineral deficiency, such as osteoporosis, scaffolds are needed that can assist in the bone regeneration process. Currently, natural polymeric scaffolds and bioactive nanoparticles stand out. Therefore, the objective of the study was to evaluate the osteoregenerative potential in tibiae of healthy and ovariectomized rats using mineralized collagen and nanohydroxyapatite (nHA) scaffolds associated with elastin. The in-vivo experimental study was performed with 60 20-week-old Wistar rats, distributed into non-ovariectomized (NO) and ovariectomized (O) groups, as follows: Controls (G1-NO-C and G4-O-C); Collagen with nHA scaffold (G2-NO-MSH and G5-O-MSH); and Collagen with nHA and elastin scaffold (G3-NO-MSHC and G6-O-MSHC). The animals were euthanized 6 weeks after surgery and the samples were analyzed by macroscopy, radiology, and histomorphometry. ANOVA and Tukey tests were performed with a 95% CI and a significance index of p < 0.05. In the histological analyses, it was possible to observe new bone formed with an organized and compact morphology that was rich in osteocytes and with maturity characteristics. This is compatible with osteoconductivity in both matrices (MSH and MSHC) in rats with normal conditions of bone metabolism and with gonadal deficiency. Furthermore, they demonstrated superior osteogenic potential when compared to control groups. There was no significant difference in the rate of new bone formation between the scaffolds. Ovariectomy did not exacerbate the immune response but negatively influenced the bone-defect repair process.

BACKGROUND: Inflammatory Bowel Disease (IBD) is an inflammatory and chronic disease, as well as non-alcoholic fatty liver disease (NAFLD). Current literature has shown that IBD patients are at high risk for NAFLD. In those patients, the pathogenesis of NAFLD may be more complex and related to multifactor causes, such as gut dysbiosis, unhealthy nutritional behavior, body composition and systemic inflammation. There is an increase in NAFLD's incidence in the general population, otherwise, there are few studies evaluating NAFLD prevalence in IBD patients. So, this study aimed to evaluate prevalence of NAFLD and identify the clinical factors associated with the presence of NAFLD in patients with IBD. METHODS: This cross-sectional, descriptive, observational study included 71 IBD patients from an IBD public outpatient in São Paulo State, Brazil. Laboratory evaluation and clinical data were collected. The presence of NAFLD was evaluated by ultrasonography. The exclusion criteria were as follows: pre-existing liver disease, history of alcohol intake >20g/day for women and >30g/day for men, and glucocorticoids treatment >20mg/day. Statistical analysis: descriptive statistics and association tests. RESULTS: 71 patients were included, of which 34 (47.89%) were Crohn´s disease (CD) and 37 (52.11%) ulcerative colitis (UC). Median age was 45.32±13.59 years, 63.38% were female, 69.1% Caucasian, 7.04% smokers. The time from diagnosis was 12.55 ± 8.01 years. Regarding the characteristics of the diseases, 42.42% of patients with CD have ileocolonic involvement, 50% penetrating disease and 39.4% perianal involvement. In relation to patients with UC, most patients have pancolitis (72.22%). Mostly, the patients were in clinical (63.89%) and endoscopic (52.86%) remission. Regarding medical treatment, the most used drugs were biological therapy (79.41%) and azathioprine (52.94%) in CD, and mesalazine (45.95%), azathioprine (40.54%) and biological therapy (40.54%) in UC. The NAFLD group consists of 32 (45.07%) patients: 40.63% had mild steatosis; 40.63% moderate and 18.65% intense NAFLD. Development of NAFLD vs no NAFLD was associated with body mass index (29.49 ± 3.93 vs 24.32 ± 3.85, p < 0.0001), and laboratory biomarkers, such as C-reactive protein (1.99 ± 4.39 vs 0.87 ± 0.52, p = 0.0061), AST (29.72 ± 16.64 vs 23.46 ± 5.31, p = 0.0226), ALT (24.92 ± 14.22 vs 17.92 ± 6.57, p = 0.0099), albumin (4.1 ± 0.37 vs 4.36 ± 0.32, p = 0.0415), fasting glucose (95.5 ± 14.01 vs 84.36 ± 13.01, p = 0.0251) and blood insulin (18.41 ± 11.88 vs 6.4 ± 4.26, p = 0.0054). Also, the NAFLD group had higher prevalence of systemic arterial hypertension (31.25% vs 10.26%, p = 0.0369). When comparing patients with the presence or absence of NAFLD, there was no difference between the groups regarding time since diagnosis (p = 0.9684), previous surgery (p = 0.5908), Montreal classification, clinical activity assessed by CDAI (p = 0.2258), clinical activity assessed by the Mayo score (p = 0.4935), endoscopic activity (p = 0.0599), histological activity (p = 1.0), or medical treatment. CONCLUSION: Development of NAFLD is a frequent occurrence in patients with IBD. NAFLD group had higher levels of body mass index, C-reactive protein, AST, ALT, fasting glucose and blood insulin, which are also associated with metabolic syndrome. Early diagnosis and appropriate nutritional orientation are necessary to prevent NAFLD related complications.
RESUMO
BACKGROUND: Inflammatory Bowel Disease (IBD), which can be divided into Crohn's Disease (CD) and Ulcerative Colitis (UC), is an immune mediated disease featured by gastrointestinal tract involvement. Hepatic disease, such as non-alcoholic fatty liver disease (NAFLD), cirrhosis, cholelithiasis, hepatic thromboembolic events and primary sclerosing cholangitis (PSC) are some hepatic complications presented by IBD patients. Since these hepatic disorders have a higher prevalence in IBD patients, ultrasonography is a noninvasive low-cost versatile tool, that allows to identify these manifestations at early stages. Therefore, this study aims to analyze the prevalence of hepatic diseases in patients with IBD. METHODS: A cross-sectional study was performed in a single IBD center, Brazil. This study considered clinical and sociodemographic data of these individuals, besides the evaluation of disease activity, biochemical tests, and liver ultrasound with doppler. Statistical analysis: descriptive, association tests. RESULTS: 71 patients were included, 34 had CD and 37 had UC, mean age 45.32 ± 13.59 years, 63.38% women. Among CD patients, 42.42% have ileocolonic involvement, 50% penetrating behavior and 39.4% perianal involvement. Among patients with UC, most patients have pancolitis (72.22%). Most patients were in clinical (CD: 93.55%, UC: 63.89%) and endoscopic (47.14%) remission. The main medications used were azathioprine (46.48%), infliximab (40.85%), salicylates (28.17%), corticosteroids (16.9%) and adalimumab (11.27%). According to ultrasound, NAFLD was found in 32 (45.07%) patients: 40.63% mild, 40.63% moderate and 18.75% severe. Furthermore, we found a correlation between liver steatosis and blunt liver edge (p < 0.0155). Only 2 patients presented with choledocholithiasis. One patient had features of chronic liver disease such as irregular surface, heterogeneity of a hepatic parenchymal echo and bluntness of the liver edge. No signs of thrombosis were found in portal, splenic or superior mesenteric veins. CONCLUSION: A higher prevalence of NAFLD was found in patients with IBD, and no signs of thrombosis were found in the splanchnic system.
RESUMO
Objective: Determine the reliability of three different methods of evaluating bone shortening in displaced midshaft clavicle fractures (DCMF). Method: A cross-sectional analytical study evaluated bone shortening by metric tape (MT), radiography (X-ray), and computed tomography (CT). Twenty-six men had been evaluated and used clavícula not broken as control. The collection of data was of the blind type for three specialists. Differences and reliability were analyzed with the Friedman and Kappa tests and validated with the T-test (CI: 95%; significance index p<0.05; Software "R" version 3.2.2). Results: The MT measurements (control) showed abnormal distribution and significant statistical difference concerning the imaging tests (p=0.000008). There was a similarity between X-ray and CT and Kappa agreement of 0.65. The fractured clavicles presented similar measurements between the three methods (p=0.059), and the T-tests proved that the similarity was caused by chance or possible measurement errors. Conclusion: Measurement by metric tape showed a tendency to overestimate bone shortening. The CT showed more reliable results for the diagnosis; however, the X-ray was sufficient for decision-making by surgeons, and therefore, it is not possible to rule out the importance of this resource for DCMF. Level of Evidence IV; Case-Control Study.
Objetivo: Determinar a confiabilidade de três diferentes métodos de avaliação do encurtamento ósseo em fraturas deslocadas do eixo médio da clavícula (FDEMC). Método: Estudo analítico transversal que avaliou o encurtamento ósseo por fita métrica (FM), radiografia (X-Ray) e tomografia computadorizada (TC). Foram avaliados 26 homens utilizando a clavícula não fraturada como controle. A coleta de dados foi do tipo cega por três especialistas. As diferenças e a confiabilidade foram analisadas com os testes de Friedman e Kappa e validados com o teste T (IC:95%; índice de significância p<0,05; Software "R" versão 3.2.2). Resultados: As medidas de FM (controle), apresentaram distribuição anormal e diferença estatísfica significativa em relação aos exames de imagem (p=0,000008). Houve semelhança entre radiografia e TC, concordância Kappa 0,65. As clavículas fraturadas apresentaram medidas semelhantes entre os três métodos (p=0,059) e os testes-T comprovaram que a semelhança foi provocada casualmente ou possíveis erros de medição. Conclusão: A medição por fita métrica apresentou tendência em superestimação do encurtamento ósseo. A TC apresentou resultados mais confiáveis para o diagnóstico, contudo, a radiografia foi suficiente para tomada de decisão dos cirurgiões e por isso, não é possível descartar a importância deste recurso para FDEMC. Nível de Evidência IV; Estudo Caso Controle.
RESUMO
Objective The objective of the present study was to evaluate the efficacy and safety of superior capsular reconstruction (SCR) using fascia lata allograft. Methods A prospective case series of 15 patients with irreparable supraspinatus tear who underwent SCR using fascia lata allograft. The American Shoulder and Elbow Surgeons (ASES) scale at 12 months after surgery was the primary outcome. The University of California Los Angeles (UCLA), Constant-Murley, and Single Assessment Numeric Evaluation (SANE) scales, in addition to the range of motion, were secondary outcomes. Radiological parameters were also evaluated by simple radiographs and magnetic resonance imaging (MRI). Results Fifteen patients completed 12 months of postoperative follow-up. The ASES score increased from 34.0 to 73.0 ( p = 0.005). The UCLA, Constant-Murley, and SANE scales also showed statistically significant differences ( p = 0.001; p = 0.005; and p = 0.046). In the evaluation of range of motion, there was improvement in elevation and in external rotation (95 to 140°, p = 0.003; 30 to 60°, p = 0.007). Six patients (40%) had complete graft healing. The clinical outcomes were significantly higher in the patients who presented graft healing. Conclusions Superior capsular reconstruction using a fascia lata allograft is a safe and effective procedure in short follow-up. Level of Evidence IV; Therapeutic Study; Case Series.
RESUMO
BACKGROUND The severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), which manifests mainly as a respiratory condition, has become a global pandemic that causes coronavirus disease-2019 (COVID-19). Although the symptoms remain mild in most patients, the elderly and patients with previous comorbidities have higher rates of morbidity and mortality. Patients with liver cirrhosis, especially after decompensation, may be more susceptible to SARS-CoV-2 infection due to systemic immune dysfunction. CASE REPORT The patient was a 51-year-old man who was hypertensive, an ex-alcoholic abstinent for 6 months, and a smoker. He was diagnosed with alcoholic liver cirrhosis in July 2019, and was using norfloxacin at home for secondary prophylaxis of bacterial peritonitis. He was also using furosemide and spironolactone to control ascites and propranolol for primary prophylaxis of esophageal varices. The patient entered our hospital in July 2020 with cough, dyspnea, runny nose, diarrhea, and fever. During hospitalization, we confirmed infection by COVID-19 and secondary nosocomial pulmonary infection. Chest tomography compatible with ground-glass standard was performed. The patient developed the need for auxiliary oxygen but without invasive mechanical ventilation. The patient received dexamethasone 6 mg/day and broad-spectrum antibiotic therapy (he was started on cefepime but switched to meropenem). At the end of the 14-day isolation period, he was discharged with improved respiratory status. CONCLUSIONS Despite high mortality rates in patients with advanced cirrhosis who become infected with COVID-19, we report a case with a favorable outcome. Success has been achieved with the use of medications in studies of broad-spectrum antibiotics and the rapid detection of complications caused by the virus. Further studies in SARS-CoV-2 patients with chronic liver disease are needed.

BACKGROUND: Anti-tumor necrosis factor agents were the first biologic therapy approved for the management of Crohn's disease (CD). Heart failure (HF) is a rare but potential adverse effect of these medications. The objective of this report is to describe a patient with CD who developed HF after the use of infliximab. CASE SUMMARY: A 50-year-old woman with a history of hypertension and diabetes presented with abdominal pain, diarrhea, and weight loss. Colonoscopy and enterotomography showed ulcerations, areas of stenosis and dilation in the terminal ileum, and thickening of the intestinal wall. The patient underwent ileocolectomy and the surgical specimen confirmed the diagnosis of stenosing CD. The patient started infliximab and azathioprine treatment to prevent post-surgical recurrence. At 6 mo after initiating infliximab therapy, the patient complained of dyspnea, orthopnea, and paroxysmal nocturnal dyspnea that gradually worsened. Echocardiography revealed biventricular dysfunction, moderate cardiac insufficiency, an ejection fraction of 36%, and moderate pericardial effusion, consistent with HF. The cardiac disease was considered an infliximab adverse effect and the drug was discontinued. The patient received treatment with diuretics for HF and showed improvement of symptoms and cardiac function. Currently, the patient is using anti-interleukin for CD and is asymptomatic. CONCLUSION: This reported case supports the need to investigate risk factors for HF in inflammatory bowel disease patients and to consider the risk-benefit of introducing infliximab therapy in such patients presenting with HF risk factors.
RESUMO
MicroRNAs (miRNAs) are non-coding RNA molecules composed of 19-25 nucleotides that regulate gene expression and play a central role in the regulation of several immune-mediated disorders, including inflammatory bowel diseases (IBD). IBD, represented by ulcerative colitis and Crohn's disease, is characterized by chronic intestinal inflammation associated with an increased risk of colorectal cancer (CRC). CRC is one of the most prevalent tumors in the world, and its main risk factors are obesity, physical inactivity, smoking, alcoholism, advanced age, and some eating habits, in addition to chronic intestinal inflammatory processes and the use of immunosuppressants administered to IBD patients. Recent studies have identified miRNAs associated with an increased risk of developing CRC in this population. The identification of miRNAs involved in this tumorigenic process could be useful to stratify cancer risk development for patients with IBD and to monitor and assess prognosis. Thus, the present review aimed to summarize the role of miRNAs as biomarkers for the diagnosis and prognosis of IBD-associated CRC. In the future, therapies based on miRNA modulation could be used both in clinical practice to achieve remission of the disease and restore the quality of life for patients with IBD, and to identify the patients with IBD at high risk for tumor development.
RESUMO
Cutaneous involvement is one of the most common extraintestinal manifestations of inflammatory bowel disease (IBD). More commonly, pyoderma gangrenosum and erythema nodosum are noted, but psoriasis, aphthous stomatitis, Sweet's syndrome, and vasculitis may also occur. Leukocytoclastic vasculitis (LCV) is a rare cutaneous manifestation, characterized by the appearance of palpable purpura, urticaria, and ulcer-necrotic lesions predominantly in the lower extremities that improve with immunosuppressive therapy. In this case, we report a patient with CD and LCV. We also searched the literature on the diagnosis and treatment of LCV in patients with CD. Female, 31, presented with diarrhea containing mucus and blood, abdominal pain, arthralgia, and enanthematous plaques and ulcers with a hematinic background in the lower extremities. The results of the colonoscopy were compatible with CD and skin biopsy showed signs of LCV. Systemic autoimmune disease and primary vasculitis were ruled out. The patient received treatment with a systemic corticosteroid and the skin lesions improved. Outpatient treatment with antitumor necrosis factor therapy was initiated to promote skin healing and IBD clinical remission. As LCV is a rare manifestation of IBD, it is necessary to distinguish this dermatopathy from other systemic vasculitis. The engagement of a multidisciplinary team is essential for the correct diagnosis and management.
RESUMO
RATIONALE: Heightened inflammatory bowel disease (IBD) activity during pregnancy is associated with higher rates of preterm birth, miscarriage, and low birth weight. Therefore, its adequate treatment is essential, considering the risk-benefit of medication use. Although previous literature has described the management of IBD during pregnancy, few studies have assessed the pharmacokinetics of IBD drugs in the newborn. In this case report, we describe the management of ulcerative colitis during pregnancy and discuss the benefits of checking serum levels of infliximab in newborns exposed to the medication during pregnancy. PATIENT CONCERN: A 37-year-old patient with ulcerative colitis in clinical and endoscopic remission had been undergoing treated with infliximab since 2008. The patient became pregnant in 2018. DIAGNOSIS AND INTERVENTION: Infliximab medication was discontinued at the 29th week of pregnancy. OUTCOMES: The pregnancy was uneventful, and the levels of infliximab in the umbilical cord were >20âµg/dL. Live vaccinations were postponed until the baby was 6âmonths old, when a new serum drug level proved to be undetectable. LESSONS: Our case suggests that the use of infliximab is safe in pregnancy, and drug discontinuation could be considered from the 24th week of pregnancy onward to reduce placental transfer to the newborn in patients at low risk of relapse. Vaccines with live attenuated organisms should be delayed for at least 6âmonths or until the serum level of the medication is undetectable.

BACKGROUND Hemangiomas are benign vascular neoplasms that originate from fast-growing embryonic mesodermal tissue and have a proliferation of endothelial cells, which manifest themselves in different forms, locations, and dimensions. Owing to its rarity and similarity of symptoms with other chronic bowel diseases, intestinal hemangioma is a differential diagnosis to be considered in patients presenting with symptoms such as abdominal pain and anemia. CASE REPORT A 46-year-old woman with a history of diffuse abdominal pain and abdominal distension for 20 years presented with a worsening of symptoms in the past year. She denied weight loss or changes in bowel habits or stool appearance. Laboratory investigations showed microcytic hypochromic anemia. Colonoscopy results were normal. A contrast-enhanced abdominal computed tomography scan showed focal and concentric thickening of the small intestine, measuring 8.3 cm, and associated with calcifications, intestinal dilation, mesenteric lymph node enlargement, and vascular dilatation and consistent with infectious granulomatous diseases such as intestinal tuberculosis, carcinoid tumor, Crohn's disease, and lymphoma. The tuberculin skin test resulted in a strong 25-mm reaction. We suspected intestinal tuberculosis or expansive injury, and the patient underwent exploratory laparotomy with visualization of a 4- to 5-cm bluish/blackish vegetating lesion located 220 cm from the Treitz angle. The anatomopathological study showed cavernous hemangioma of the small intestine, measuring 2.6×1.0 cm. The patient recovered well and remained asymptomatic. CONCLUSIONS Although rare, intestinal hemangioma should be on the list of differential diagnoses for chronic intestinal diseases, especially if there is anemia due to coexisting iron deficiency.

BACKGROUND: Hidradenitis suppurativa is a chronic inflammatory skin disorder associated with inflammatory bowel disease. However, it can arise as a paradoxical side effect of anti-TNF treatment. METHODS: The article reports on three patients with Crohn's disease who developed hidradenitis suppurativa during the treatment with adalimumab. RESULTS: Case 1: A 38-year-old female exhibited an infiltrative lesion in the inguinal region and vulva, consistent with hidradenitis suppurativa, after three months of adalimumab. These lesions were treated with partial vulvectomy. Case 2: After adalimumab treatment, a 27-year-old female, originally diagnosed with ileocolonic Crohn's disease, went into clinical and endoscopic remission. The patient eventually presented two hyperchromic nodules in the inguinal region, which were diagnosed as hidradenitis suppurativa. The patient showed improvement after treatment with oral doxycycline and local therapy. Case 3: A 34-year-old female with fistulizing and stenosing ileocolonic Crohn's disease, started adalimumab in 2010, with optimization in 2015. One year after, the patient developed bilateral, erythematous, hardened, inguinal nodulations with purulent drainage, consistent with hidradenitis suppurativa. Treatment with oral doxycycline, fusidic acid, and infiltration with triamcinolone resulted in partial improvement of the lesions. In 2018, the lesions deteriorate. The patient underwent surgical treatment. CONCLUSION: Patients with inflammatory bowel disease are more likely to the development of other mediated inflammatory diseases, such as hidradenitis suppurativa. Hidradenitis suppurativa may appear as a paradoxical reaction to anti-TNF therapy. Clinical teams must be aware of this type of complication. Early diagnosis and treatment are essential for controlling the disease and preventing the onset of complications.

RESUMO
Superior capsular reconstruction is a recently described procedure for the treatment of irreparable supraspinatus tendon tears. Graft options that have been previously described include autogenous fascia lata and decellularized dermal graft. No studies were published with the use of fascia lata allograft. The purpose of this technical note is to describe the surgical technique of superior capsular reconstruction using fascia lata allograft. The procedure is performed by arthroscopic visualization, with the patient positioned in the lateral decubitus position. The authors describe a technique based on the use of a double-pulley knot in the glenoid and greater tuberosity, facilitating the procedure and allowing the graft to be brought into the subacromial space in the definitive position, with the appropriate tension. The allografts are available from this institution's tissue bank, cryopreserved and submitted to microbiological and histopathological evaluation. Superior capsular reconstruction is a promising surgery. The technique described in the present technical note shows a viable arthroscopic alternative, with a smaller number of anchors when compared with other techniques.
RESUMO
OBJECTIVE: To assess the historical trend of rotator cuff repairs in Brazil between 2003 and 2015, using the database of the Brazilian Unified Health System's (Sistema Único de Saúde [SUS]) Department of Informatics (DataSUS). METHODS: Historical series using DataSUS. Surgeries performed between 2003 and 2015 were included and data relating to cuff tear repair were assessed, including decompression procedures were included. The numerator was the total number of rotator cuff repair and the denominator, the total population of the assessed locality. Population data were based on information from the Instituto Brasileiro de Geografia e Estatística (IBGE). RESULTS: During the period, 50,207 surgeries were performed. The rate was presented as number of procedures per 100,000 inhabitants, and increased from 0.83 to 2.81, a growth of 238%. In 2015, the South region had the highest rate, 6.32, followed by the Southeast, 3.62, while the North had the lowest rate, 0.13. The growing trend can be observed in the Southeast, South, and Midwest, while the rate is stable in the North and Northeast. CONCLUSION: The rate of rotator cuff repairs in Brazil performed through the SUS increased from 0.83 to 2.81 between 2003 and 2015, representing a growth of 238%, but remains lower than that of developed countries. A trend of growth can be observed in the Southeast, South, and Midwest, while the rate is stable in the North and Northeast.

Resumo Objetivo O objetivo do presente estudo foi avaliar a eficácia e a segurança da reconstrução capsular superior (RCS) com a utilização do aloenxerto de fáscia lata. Métodos Uma série de casos prospectivos de 15 pacientes com ruptura irreparável do supraespinhal foi submetida a RCS com aloenxerto de fáscia lata, sendo adotada como desfecho primário a escala American Shoulder and Elbow Surgeons (ASES, na sigla em inglês) aos 12 meses do pós-operatório. Como desfechos secundários, foram adotadas as escalas da University of California Los Angeles (UCLA, na sigla em inglês), Constant-Murley, e Single Assessment Numeric Evaluation (SANE, na sigla em inglês), além da amplitude de movimento. Os parâmetros radiológicos também foram avaliados por radiografias simples e ressonância magnética (RM). Resultados Quinze pacientes completaram 12 meses de acompanhamento pós-operatório. O escore ASES aumentou de 34,0 para 73,0 (p= 0,005). As escalas UCLA, Constant-Murley e SANE também apresentaram diferenças estatisticamente significativas (p= 0,001; p= 0,005; e p= 0,046). Na avaliação da amplitude de movimento, houve melhora na elevação e rotação externa (95 a 140°, p= 0,003; 30 a 60°, p= 0,007). Seis pacientes (40%) tiveram cicatrização completa do enxerto. Os desfechos clínicos foram significativamente maiores nos pacientes que apresentaram cicatrização do enxerto. Conclusões A RCS com aloenxerto de fáscia lata é um procedimento seguro e eficaz com um curto acompanhamento de tempo. Nível de evidência IV; Estudo Terapêutico; Série de casos.

Abstract Superior capsular reconstruction is a recently described procedure for the treatment of irreparable supraspinatus tendon tears. Graft options that have been previously described include autogenous fascia lata and decellularized dermal graft. No studies were published with the use of fascia lata allograft. The purpose of this technical note is to describe the surgical technique of superior capsular reconstruction using fascia lata allograft. The procedure is performed by arthroscopic visualization, with the patient positioned in the lateral decubitus position. The authors describe a technique based on the use of a double-pulley knot in the glenoid and greater tuberosity, facilitating the procedure and allowing the graft to be brought into the subacromial space in the definitive position, with the appropriate tension. The allografts are available from this institution's tissue bank, cryopreserved and submitted to microbiological and histopathological evaluation. Superior capsular reconstruction is a promising surgery. The technique described in the present technical note shows a viable arthroscopic alternative, with a smaller number of anchors when compared with other techniques.
Resumo A reconstrução da cápsula superior é um procedimento descrito recentemente para o tratamento das roturas irreparáveis do tendão do músculo supraespinal. Como opções de enxerto podemos citar o uso de fáscia lata autógena e enxerto dermal acelularizado. Nenhum estudo foi publicado com o uso de aloenxerto de fáscia lata. O objetivo desta nota é descrever a técnica cirúrgica da reconstrução da cápsula superior com aloenxerto de fáscia lata. O procedimento é feito por visão artroscópica, com o paciente posicionado em decúbito lateral. Os autores descrevem uma técnica baseada no uso do nó em dupla polia na glenoide e no tubérculo maior, que facilita o procedimento e permite que o enxerto seja levado para o espaço subacromial na posição definitiva e com a tensão adequada. Os aloenxertos usados são provenientes de banco de tecidos, onde são criopreservados e submetidos à avaliação microbiológica e histopatológica. A reconstrução da cápsula superior é uma cirurgia promissora. A técnica descrita mostra uma opção artroscópica viável, com uso de menor número de âncoras quando comparada com as demais descrições.

ABSTRACT OBJECTIVE: To assess the historical trend of rotator cuff repairs in Brazil between 2003 and 2015, using the database of the Brazilian Unified Health System's (Sistema Único de Saúde [SUS]) Department of Informatics (DataSUS). METHODS: Historical series using DataSUS. Surgeries performed between 2003 and 2015 were included and data relating to cuff tear repair were assessed, including decompression procedures were included. The numerator was the total number of rotator cuff repair and the denominator, the total population of the assessed locality. Population data were based on information from the Instituto Brasileiro de Geografia e Estatística (IBGE). RESULTS: During the period, 50,207 surgeries were performed. The rate was presented as number of procedures per 100,000 inhabitants, and increased from 0.83 to 2.81, a growth of 238%. In 2015, the South region had the highest rate, 6.32, followed by the Southeast, 3.62, while the North had the lowest rate, 0.13. The growing trend can be observed in the Southeast, South, and Midwest, while the rate is stable in the North and Northeast. CONCLUSION: The rate of rotator cuff repairs in Brazil performed through the SUS increased from 0.83 to 2.81 between 2003 and 2015, representing a growth of 238%, but remains lower than that of developed countries. A trend of growth can be observed in the Southeast, South, and Midwest, while the rate is stable in the North and Northeast.
RESUMO OBJETIVO: Avaliar a tendência histórica de reparos do manguito rotador no Brasil, entre 2003 e 2015, com o uso do banco de dados do Departamento de Informática do SUS (DataSUS). MÉTODOS: Série histórica com o uso do DataSUS. Foram incluídas cirurgias feitas entre 2003 e 2015 e coletados os dados referentes ao reparo de rotura do manguito, incluindo procedimentos descompressivos. Usamos como numerador o total de reparos do manguito rotador e como denominador a população total da localidade avaliada. Dados populacionais foram baseados nas informações do Instituto Brasileiro de Geografia e Estatística (IBGE). As taxas foram apresentadas por grupo de 100.000 habitantes. RESULTADOS: Durante o período, foram registradas 50.207 cirurgias. A taxa aumentou de 0,83 para 2,81, um acréscimo de 238%. Em 2015, a Região Sul apresentou a maior taxa, 6,32, seguida da Sudeste, 3,62, enquanto a Norte apresentou a menor taxa, 0,13. A tendência crescente pode ser observada nas regiões Sudeste, Sul e Centro-Oeste, enquanto o índice é estável nas regiões Norte e Nordeste. CONCLUSÃO: A taxa de reparos do manguito rotador no Brasil feitos pelo Sistema Único de Saúde aumentou de 0,83 para 2,81 entre 2003 e 2015, um aumento de 238%, mas permanece inferior à dos países desenvolvidos. Uma tendência crescente pode ser observada nas regiões Sudeste, Sul e Centro-Oeste, enquanto a taxa é estável nas regiões Norte e Nordeste.
