Real-world data of Brazilian adults with X-linked hypophosphatemia (XLH) treated with burosumab and comparison with other worldwide cohorts.

BACKGROUND: Disease-related variants in PHEX cause XLH by an increase of fibroblast growth factor 23 (FGF23) circulating levels, resulting in hypophosphatemia and 1,25(OH)2 vitamin D deficiency. XLH manifests in early life with rickets and persists in adulthood with osseous and extraosseous manifestations. Conventional therapy (oral phosphate and calcitriol) improves some symptoms, but evidence show that it is not completely effective, and it can lead to nephrocalcinosis (NC) and hyperparathyroidism (HPT). Burosumab (anti-FGF23 antibody) has shown to be effective and safety in the clinical trials. METHODS: The current real-world collaborative study evaluated genetic, clinical and laboratory data of XLH Brazilian adult patients treated with burosumab. RESULTS: Nineteen unrelated patients were studied. Patients reported pain, limb deformities and claudication, before burosumab initiation. 78% of them were previously treated with conventional therapy. The severity of the disease was moderate to severe (15 patients with score >5). At the baseline, 3 patients presented NC (16.7%) and 12 HPT (63%). After 16 ± 8.4 months under burosumab, we observed a significant: increase in stature (p = 0.02), in serum phosphate from 1.90 ± 0.43 to 2.67 ± 0.52 mg/dL (p = 0.02); in TmP/GFR from 1.30 ± 0.46 to 2.27 ± 0.64 mg/dL (p = 0.0001), in 1,25 (OH)2 D from 50.5 ± 23.3 to 71.1 ± 19.1 pg/mL (p = 0.03), and a decrease in iPTH from 86.8 ± 37.4 pg/mL to 66.5 ± 31.1 (p = 0.002). Nineteen variants were found (10 novel). HPT tended to develop in patients with truncated PHEX variants (p = 0.06). CONCLUSIONS: This study confirms the efficacy and safety of burosumab on XLH adult patients observed in clinical trials. Additionally, we observed a decrease in iPTH levels in patients with moderate to severe HPT at the baseline.

Phase angle values and ultra-processed food consumption are associated with changes in oxidative stress in inflammatory bowel disease patients.

BACKGROUND & AIMS: Changes in dietary habits including increased intake of refined sugars and fats and decreased intake of fiber have been suggested as potential risk factors for the development of inflammatory bowel diseases (IBD). Bioelectrical impedance analysis-derived phase angle (PhA) has been gaining attention in the clinical evaluation of nutritional status. In this study, we for the first time investigated the relationship of PhA and ultra-processed food intake with oxidative stress, body composition and biochemical parameters in adult patients with IBD. METHODS: Body composition and PhA were evaluated through electrical bioimpedance. Nitrite (Nox), myeloperoxidase (MPO), glutathione (GSH), malondialdehyde (MDA) and superoxide dismutase (SOD) levels were determined in both groups. Food consumption was obtained by a food frequency questionnaire (FFQ). RESULTS: In comparison with the control group, the IBD group had increased (p < 0.05) concentrations of Nox (19.95 ± 1.4 vs. 35.43 ± 7.7 µM), MDA (0.70 ± 0.31 vs. 4.56 ± 0.62 nmol/L), and GSH (9.35 ± 0.38 vs. 10.74 ± 0.51 mg NPSH/µL plasma). PhA was positively correlated with GSH (R2:0.22; p:0.02) and SOD (R2:0.25; p:0.01). IBD patients ingested higher amounts of ultra-processed foods (IBD:17.04 ± 2.76 vs. Control:24.88 ± 2.30%). However, IBD patients had better consumption of unprocessed or minimally processed foods (IBD:79.06 ± 3.07 vs. Control:67.83 ± 2.32%). We found a positive correlation between ultra-processed food consumption and MDA (R2 0.43; p:0.01). CONCLUSIONS: PhA may be a practical and effective measure in clinical follow-up of IBD patients, being associated with bilirubin levels and antioxidant enzymes. Also, we recommend evaluating consumption of ultra-processed foods, since this was related with increasing oxidative stress markers in clinical follow-up of IBD patients.

Physical exercise alleviates oxidative stress in brown adipose tissue and causes changes in body composition and nutritional behavior in rats with polycystic ovary syndrome.

AIM: Polycystic Ovary Syndrome (PCOS) is a very common endocrine disorder in women. We investigate the effect of physical exercise on body composition, nutritional parameters, and oxidative stress in rats with PCOS. METHODS: Female rats were into three groups: Control, PCOS, and PCOS + Exercise. PCOS was induced by letrozole (1 mg/kg via p.o.) for 21 days consecutively. Physical exercise was swimming, for 21 consecutive days, 1 h/day with 5 % load. In all groups, we assessed the nutritional and murinometric parameters, body composition, thermography, and oxidative stress in brown adipose tissue (BAT) and peri-ovarian adipose tissue (POAT). KEY FINDINGS: In PCOS we observed an increase (P < 0.05) in body weight vs. the Control group. But, the PCOS + Exercise group prevent this weight gain (P < 0.05). The temperature in BAT, decrease (P < 0.05) in the PCOS group vs. Control group. PCOS + Exercise prevented this reduction (P < 0.05) in BAT temperature vs. PCOS groups. We observed decreases (P < 0.05) in Lee Index and BMI in POS + Exercise vs. PCOS group. In PCOS rats, we observed an increase (P < 0.05) in murinometric (SRWG, EI, and FE) and body composition parameters (TWB, ECF, ICF, and FFM) vs. the Control group. The PCOS + Exercise prevents (P < 0.05) these changes in all groups, compared with PCOS. Regarding the BAT, we observe an increase (P < 0.05) in MPO and MDA levels in the PCOS vs. Control group. PCOS + Exercise prevents (P < 0.05) these increases vs. the PCOS group. SIGNIFICANCE: PCOS modifies body composition, and nutritional parameters, and induces changes in oxidative stress in BAT. Physical exercise prevented these alterations.

Acquired Hip Dysplasia in Children with Congenital Zika Virus Infection in the First Four Years of Life.

Acquired hip dysplasia has been described in children with cerebral palsy (CP); periodic surveillance is recommended in this population to prevent hip displacement and dislocation. Children with congenital zika syndrome (CZS) may present a spectrum of neurological impairments with changes in tonus, posture, and movement similar to children with CP. However, the relationship between CZS and hip dysplasia has not been characterized. In this prospective cohort study, we aimed to describe the occurrence of hip dysplasia in patients with CZS. Sixty-four children with CZS from 6 to 48 months of age were included and followed at a tertiary referral center in Rio de Janeiro, Brazil, with periodic radiologic and clinical hip assessments. Twenty-six (41%) patients were diagnosed with hip dysplasia during follow-up; mean age at diagnosis was 23 months. According to the Gross Motor Function Classification System (GMFCS), 58 (91%) patients had severe impairment (GMFCS IV and V) at the first evaluation. All patients with progression to hip dysplasia had microcephaly and were classified as GMFCS IV or V. Pain and functional limitation were reported by 22 (84%) caregivers of children with hip dysplasia. All patients were referred to specialized orthopedic care; eight (31%) underwent surgical treatment during follow-up. Our findings highlight the importance of implementing a hip surveillance program and improving access to orthopedic treatment for children with CZS in order to decrease the chances of dysplasia-related complications and improve quality of life.

Teaching medical students to choose wisely through simulation.

The Choosing Wisely (CW) campaign aims to encourage dialog among physicians and patients about the costs and benefits of medical care. The purpose of the present study was to describe the implementation of the CW campaign among medical students in the pediatrics clerkship using different teaching strategies and to evaluate the students' perception and performance. A prospective, interventionist, open study with a control group was conducted. All sixth-year undergraduate medical students that were on their pediatric clerkship at the Emergency Department during the study period were invited to participate. The study consisted of two strategies: a remote video class about the CW initiative and in situ simulation training. By the end of the rotation, all participants were evaluated through an Objective Structured Clinical Examination (OSCE). A total of 50 students were included, of which 24 watched only the online video (control group) and 26 were exposed to both the online video and the simulation scenarios (intervention group). Students in the intervention group had a significantly higher total score in the OSCE compared to students in the control group (median 90 vs 90; range 78-100 vs 50-100; p: 0.047). Median scores of behavioral items of the OSCE grouped together were significantly higher in the intervention group compared to the control group (median 60 vs 50; range 40-60 vs 20-60; p: 0.002).Conclusion: Simulation training about principles of the CW campaign had a greater impact on behavioral aspects of undergraduate students. This learning strategy was well accepted by participants. What is Known: • The Choosing Wisely (CW) campaign aims to encourage dialog among physicians and patients about the costs and benefits of medical care. • Teaching high-value and cost-conscious care to medical students is highly desired.. What is New: • Simulation training about principles of the CW campaign had a greater impact on behavioral aspects of undergraduate students.

Platelet-Rich Plasma Versus Hyaluronic Acid for Knee Chondral Injuries In Young Patients.

Objective The present study aimed to compare the clinical and functional outcomes of hyaluronic acid (HA) or platelet-rich plasma (PRP) applications to treat young patients with knee chondral lesions with no arthrosis. Methods Prospective clinical and functional evaluation of 30 young adult patients with knee chondral lesions submitted to conservative treatment with HA or PRP for a minimum follow-up time of 12 months. The Western Ontario and McMaster Universities Arthritis Index (WOMAC) and visual analog scale (VAS) were used for the evaluation. Results According to the WOMAC score, the PRP group showed significant improvement in all evaluated points, whereas the HA group presented no score improvement. In the VAS, the PRP group showed improvement in all evaluated points, and the HA group presented improvement at 6 and 12 months. Compared to the HA group, the PRP group presented better WOMAC scores at all evaluated points and better VAS scores up to 6 months after treatment. Conclusion Platelet-rich plasma application resulted in better clinical and functional outcomes at both the WOMAC and VAS scores when applied to knees from young patients with chondral lesions, but no arthrosis. These outcomes were sustained for up to 12 months. Level of evidence Randomized clinical trial (Type 2B).

Moderate Physical Exercise Activates ATR2 Receptors, Improving Inflammation and Oxidative Stress in the Duodenum of 2K1C Hypertensive Rats.

Background: In addition to the cardiovascular and renal systems, the gastrointestinal tract also contains angiotensin ATR1a, ATR1b, and ATR2. We previously observed that the 2Kidney-1Clip hypertension model elicits physical exercise and gastrointestinal dysmotility, which is prevented by renin-angiotensin system blockers. Here, we investigate the effect of physical exercise on inflammation, stress biomarkers, and angiotensin II receptors in the duodenum of 2K1C rats. Methods: Arterial hypertension was induced by the 2K1C surgical model. The rats were allocated in Sham, 2K1C, or 2K1C+Exercise groups. One week after surgery, they were submitted to a physical exercise protocol (running 5x/week, 60min/day). Next, we assessed their intestinal contractility, cytokine levels (TNF-α, IL-1ß, and IL-6), oxidative stress levels (MPO, GSH, MDA, and SOD), and the gene expression of angiotensin receptors (ATR1A, ATR1B, and ATR2). Results: In comparison with the Sham group, the 2K1C arterial hypertension decreased (p<0.05) the intestinal contractility. In comparison with 2K1C, the 2K1C+Exercise group exhibited lower (p<0.05) MPO activity (22.04±5.90 vs. 78.95±18.09 UMPO/mg tissue) and higher (p<0.05) GSH concentrations in intestinal tissues (67.63±7.85 vs. 31.85±5.90mg NPSH/mg tissue). The 2K1C+Exercise group showed lower (p<0.05) cytokine levels in the intestine than 2K1C rats. In comparison with the Sham group, the 2K1C+Exercise rats showed higher (p<0.05) gene expression of ATR2 in the duodenum. Conclusion: 2K-1C hypertension elicits an oxidative stress and inflammation process in the duodenum. Physical exercise modulates the expression twice as much of ATR2 receptors, suggesting possible anti-inflammatory and antioxidant effects induced by exercise.

Effect of dietary interventions on inflammatory biomarkers of inflammatory bowel diseases: A systematic review of clinical trials.

OBJECTIVES: In this review, we systematically assess whether dietary interventions are effective in attenuating inflammatory biomarkers in IBDs based on clinical trials available in the literature. RESEARCH METHODS & PROCEDURES: This review was conducted in accordance with the guidelines of the PRISMA. We used the PubMed and SciVerse Scopus databases and the Cochrane collaboration tool to assess the risk of bias in clinical trials. The PICO (patient, intervention, comparison, and outcomes) strategy was used, with the descriptors: "Inflammatory bowel disease", "Crohn's disease", "cd", "ibd", "ulcerative colitis", "uc", "Diet", "Diet Habits", "Feeding", "Nutrients", "Food Intake", "Dietary patterns", "Inflammations", "Inflammation", "acute-phase proteins", "C-reactive protein", "interleukins", "tumor necrosis factor-alpha" and "inflammatory response". There is no conflict of interest. DATA ANALYSIS: Fifteen studies were included, with a total of 627 participants. Of the total studies included, seven showed a reduction in some inflammatory markers in response to dietary interventions. This review was registered with the PROSPERO platform under number: CRD42021235150. CONCLUSIONS: The results presented in this review reveal that dietary intervention with specific characteristics may be important during the treatment of the inflammatory process in patients with IBDs.

COVID-19: ANALYSIS OF CONFIRMED CASES IN TERESINA, PIAUI, BRAZIL / COVID-19: ANÁLISE DE CASOS CONFIRMADOS EM TERESINA, PIAUI, BRASIL

Introduction: Coronavirus are microorganisms responsible for causing respiratory infections that can vary from asymptomatic to severe. The spread of the virus around the world has led to a pandemic position, which has claimed numerous victims. Given the magnitude of the problem, the study aims to analyze the epidemiological profile of confirmed cases of COVID-19 in Teresina-PI. Design: Descriptive and epidemiological study. The study population consisted of 315 confirmed cases of Covid-19, in individuals residing in the city of Teresina-PI, between March and April 2020. The variables evaluated were: age group, sex, deaths confirmed by Covid- 19 and confirmed cases of Covid-19 by area of ​​the city. Results: There was a predominance of confirmed cases of Covid-19 in young, female individuals living in an urban area of ​​Teresina. Most deaths occurred in the elderly, being more prevalent in males. Implications: The epidemiological monitoring of cases strengthens the need to implement preventive measures, such as social containment. In addition, the expansion of testing in the population is important in order to identify asymptomatic cases and, consequently, to prevent the spread of the coronavirus, considering that these cases favor the transmission chain.

Perthes-Like Disease Masquerading Non-Classical MPS

Abstract Mucopolysaccharidoses (MPS) are inborn errors of metabolism caused by deficient lysosomal enzymes, leading to organomegaly, hip osteonecrosis, coarse facial features, bone deformities, joint stiffness, cardiac and pulmonary symptoms (MPS VI) or hypermobility (MPS IVA). Some patients may present with non-classical forms of the disease in which osteoarticular abnormalities are the initial symptoms of non-classical forms. As orthopedists and surgeons are the specialists most frequently consulted before the diagnosis, it is critical that MPS may be considered as a differential diagnosis for patients with bone dysplasia. Experts in Latin America reviewed medical records focusing on disease onset, first symptoms and the follow-up clinical and surgical outcomes of non-classical MPS VI and IVA patients. All patients displayed orthopedic issues, which worsened over time, followed by cardiac and ophthalmological abnormalities. Our findings enlighten the necessity of including non-classical MPS as possible diagnosis for patients who report osteoarticular abnormalities in absence of inflammation.

Zika virus infection in children: epidemiology and clinical manifestations.

PURPOSE: The purpose of this review is to comprehensively review Congenital Zika Syndrome in regard to their epidemiology and clinical manifestations. METHODS: This subject review of congenital Zika syndrome was composed after conducting a thorough review of the available literature on this topic using PubMed and other primary sources. RESULTS: The first epidemic of Zika virus infection in Brazil was followed by an unexpected sharp increase in the incidence of infants born with microcephaly and the description of a new disease, the congenital Zika syndrome. This review focuses on the epidemiological and clinical aspects of Zika infection in children. We conducted a brief historical account of the virus description in 1947, the rare cases of Zika infection occurring up to 2007, and the first epidemics in the Pacific between 2007 and 2014. We also discussed the isolation of the virus in Brazil in 2015 and its spread in the Americas, the microcephaly outbreak in Brazil and its association with Zika virus, and the current epidemiological panorama. We address the known clinical spectrum of Zika virus infection in the pediatric population, including manifestations of acute infection and congenital Zika syndrome, with emphasis on cranial, ophthalmic, and orthopedic abnormalities. CONCLUSION: While much has been learned about congenital Zika syndrome, the full spectrum of this infection is not yet known. This review is based on current, limited data about Zika vírus infection. As more information becomes available, we will have a more accurate picture of this new disease.

ANALYSIS OF SURGICAL SITE INFECTIONS IN PEDIATRIC PATIENTS AFTER ORTHOPEDIC SURGERY: A CASE-CONTROL STUDY. / ANÁLISE DAS INFECÇÕES DE SÍTIO CIRÚRGICO EM PACIENTES PEDIÁTRICOS APÓS CIRURGIA ORTOPÉDICA: UM ESTUDO CASO-CONTROLE.

OBJECTIVES: To describe the rate of surgical site infections in children undergoing orthopedic surgery in centers of excellence and analyze the patients' profiles. METHODS: Medical records of pediatric patients undergoing orthopedic surgery in the Jamil Haddad National Institute of Traumatology and Orthopedics from January 2012 to December 2013 were analyzed and monitored for one year. Patients diagnosed with surgical site infection were matched with patients without infection by age, date of admission, field of orthopedic surgery and type of surgical procedure. Patient, surgical and follow-up variables were examined. Descriptive, bivariate and correspondence analyses were performed to evaluate the patients' profiles. RESULTS: 347 surgeries and 10 surgical site infections (2.88%) were identified. There was association of infections with age - odds ratio (OR) 11.5 (confidence interval - 95%CI 1.41-94.9) -, implant - OR 7.3 (95%CI 1.46-36.3) -, preoperative period - OR 9.8 (95%CI 1.83-53.0), and length of hospitalization - OR 20.6 (95%CI 3.7-114.2). The correspondence analysis correlated the infection and preoperative period, weight, weight Z-score, age, implant, type of surgical procedure, and length of hospitalization. Average time to diagnosis of infection occurred 26.5±111.46 days after surgery. CONCLUSIONS: The rate of surgical site infection was 2.88%, while higher in children over 24 months of age who underwent surgical implant procedures and had longer preoperative periods and lengths of hospitalization. This study identified variables for the epidemiological surveillance of these events in children. Available databases and appropriate analysis methods are essential to monitor and improve the quality of care offered to the pediatric population.

Surgical treatment for unstable pelvic fractures in skeletally immature patients.

OBJECTIVE: To present the results and conclusions of our study on surgical treatment for unstable pelvic fractures in children subjected to surgical reduction and stabilisation. METHODS: We analysed the cases of fourteen skeletally immature patients with unstable pelvic fractures who underwent surgery for this condition between March 2004 and January 2011. The surgical technique used was based on the principle of surgical reduction and stabilisation of anterior and posterior lesions of the pelvic ring. This was a retrospective study, based on clinical assessment and X-ray analyses. RESULTS: The mean age of patients at the time of the condition was 9.4 years (range 2-13 years). Eight patients were female and six were male. The cause of the trauma was being hit by a car in ten cases, falls in three cases and an accident involving a motorcycle in one case. Five patients presented with other associated injuries, including fracture of the clavicle, femur shaft, proximal humerus, tibial shaft or olecranon, and bladder damage. All the patients assessed showed excellent clinical progress. Pelvic asymmetry prior to surgery varied from 1.1 to 2.9 cm (mean 1.5 cm) and dropped to a range of 0.2 to 0.9 cm (mean 0.4 cm) after reduction. In none of the cases was there a change between the pelvic asymmetry measured immediately after surgery and at the end of the follow-up period. CONCLUSION: Pelvic fracture in skeletally immature patients is rare and surgery is not normally indicated. Various authors have questioned this conservative type of treatment due to complications encountered. Bone remodelling does not seem to be sufficient to ensure an improvement in pelvic asymmetry, which justifies opting for surgery to reduce and correct deformities in the pelvic ring.

Spiritual/religious coping in patients with epilepsy: relationship with sociodemographic and clinical aspects and quality of life.

One hundred and ten patients with epilepsy with a mean age of 45.9 were assessed by a clinical-neurological evaluation, Quality of Life in Epilepsy Inventory-31 (QOLIE-31), and the Spiritual/Religious Coping (SRCOPE) Scale. The objective of this study was to evaluate if patients with epilepsy used positive and/or negative spiritual/religious coping and the relationships between this type of coping and the sociodemographic and clinical aspects of epilepsy and the QOLIE-31. A greater use of positive coping (3.0±0.7) than negative coping (2.3±0.7) was found. The use of the positive factor was greater in mesial temporal lobe epilepsy (MTLE) than in other types of epilepsy. The ratio of negative/positive coping was associated with lower scores in the QOLIE-31 (-0.222; p=0.036). Patients with epilepsy appear to use spiritual/religious coping, especially those with MTLE, and a predominance of negative coping was associated with a reduced quality of life. Future studies should evaluate interventions considering the knowledge of spiritual/religious strategies by the patients.

Efeitos do aparelho de Herbst no tratamento precoce da má oclusão. Classe II de Angle / Effects of Herbst appliance in early treatment of angle Class II malocclusion

A Classe II de Angle tem sido amplamente pesquisada por diversos autores devido à grande incidência na população, juntamente os meios para o seu tratamento. Dentre os métodos de tratamento, destaca-se o aparelho de Herbst que foi reintroduzido a mais de 3 décadas na comunidade ortodôntica. Por ser um aparelho que independe da cooperação do paciente e por propiciar uma ação contínua através de tubos telescópicos bilaterais, tornou-se atualmente o aparelho mais utilizado. O objetivo deste trabalho é demonstrar o tratamento precoce da má oclusão de Classe II divisão 1ª com retrusão mandibular com o uso do aparelho de Herbst.

Due to its high prevalence in general population, Angle Class II malocclusion has been widely studied by several authors, as well as the methods for its treatment. Among the possible treatment methods stands out the Herbst appliance. Reintroduced more than three decades ago in the orthodontics community, it became the most utilized appliance because it does not require patient compliance, and provides continued action through bilateral telescopic tubes. The objective of the present article was to demonstrate the early treatment of Class II Division 1 malocclusion with mandibular retrusion using Herbst appliance.

This article aims to describe the technique of bilateral anterior pelvic osteotomy for treating bladder and cloacal exstrophy, and presents two cases to demonstrate the difficulties and applications of the technique.

SURGICAL TREATMENT OF UNSTABLE PELVIC RING FRACTURE IN SKELETALLY IMMATURE PATIENTS.

OBJECTIVES: To present the outcomes from definitive surgical treatment for unstable fractures of the pelvic ring in children undergoing surgical reduction and stabilization. METHODS: We studied 10 patients with immature skeletons who suffered unstable fractures of the pelvic ring and were treated between March 2004 and January 2008. The study was retrospective, based on clinical and radiographic evaluations. RESULTS: The mean age at the time of the trauma was 8.8 years (2 to 13 years). Seven patients were female and three was male. There were eight cases of trauma caused by being run over, and one case each of a motorcycle accident and falling from a height. Five patients had other associated injuries such as fractures of the clavicle, femoral diaphysis, proximal humerus, lower leg bones, olecranon and bladder injury. All the patients evaluated showed an excellent clinical outcome. The pelvic asymmetry before surgery ranged from 0.7 to 2.9 cm (mean 1.45 cm), and dropped to values between 0.2 and 0.9 cm (mean 0.39 cm) after reduction. In no case was any change observed in pelvic asymmetry measured in the immediate postoperative period and at the end of follow-up. CONCLUSION: Pelvic ring fractures in skeletally immature patients are rare and surgical treatment is unusual. Several authors have questioned conservative treatment because of the complications encountered. Bone remodeling does not seem enough to cause an improvement in pelvic asymmetry, and this justifies the choice of surgical treatment for reduction and correction of pelvic ring deformities.

Tratamento cirúrgico da fratura instável do anel pélvico em pacientes esqueleticamente imaturos / Surgical treatment of unstable pelvic ring fracture in skeletally immature patients

OBJETIVO: Apresentar o resultado do tratamento cirúrgico definitivo da fratura instável do anel pélvico na criança submetida a redução e estabilização cirúrgica. MÉTODOS: Avaliamos 10 pacientes com esqueleto imaturo que sofreram fraturas instáveis do anel pélvico tratados cirurgicamente no período entre março de 2004 a janeiro de 2008. O estudo foi retrospectivo, baseado na avaliação clínica e radiográfica. RESULTADOS: A média etária na época do trauma foi de 8,8 anos (dois a 13 anos), sendo sete do sexo feminino e três do sexo masculino. As causas dos traumas foram atropelamento em oito casos, e acidente com motocicleta e queda de altura em um caso cada. Cinco pacientes apresentavam lesões associadas, como fraturas da clavícula, diáfise do fêmur, úmero proximal, ossos da perna, olecrânio e lesão de bexiga. Todos os pacientes avaliados apresentaram excelente evolução clínica. A assimetria pélvica antes do procedimento cirúrgico variava de 0,7 a 2,9cm (média 1,45cm), e caiu para valores entre 0,2 a 0,9cm (média 0,39cm) após a redução. Em nenhum dos casos houve alteração da assimetria pélvica medida no pós-operatório imediato e no fim do seguimento. CONCLUSÃO: A fratura do anel pélvico em pacientes esqueleticamente imaturos é rara e a indicação de tratamento cirúrgico não é usual. Diversos autores questionam o tratamento conservador devido às complicações encontradas. A remodelação óssea não parece suficiente para que ocorra uma melhora da assimetria pélvica, fator que justifica a opção pelo tratamento cirúrgico para a redução e correção das deformidades do anel pélvico.

The cause of the trauma was being run over in eight cases, and one case each of a motorcycle accident and falling from a height. Five patients had other associated injuries such as fractures of the clavicle, femur diaphysis, proximal humerus, fibula, olecranon, and bladder injury. All patients showed an excellent clinical outcome. The pelvic asymmetry before surgery ranged from 0.7 to 2.9 cm (mean 1.45 cm), and dropped to values between 0.2 and 0.9 cm (mean 0.39 cm) after reduction.
