RESUMO

Introduction: Mental distress is highly reported in cancer patients, resulting in anxiety and depression most of the time. Both conditions, in turn, are recognized to be related to dental fear in adults; however, there are no studies on patients suffering from head and neck cancer. Thus, the present study aimed to investigate whether newly diagnosed patients with head and neck cancer are more prone to self-reported dental fear. Material and Methods: This dual-center cross-sectional study was conducted with 25 healthy outpatients and 25 patients with a recent diagnosis of head and neck cancer, all requiring dental care. The patients were informed at the first appointment about their dental therapy planning and the Brazilian Portuguese Version of the Dental Fear Survey (DFS) questionnaire was then applied after appropriate instructions. Results: The DFS total scores did not differ statistically between the groups (Mann-Whitney U test, P = 0,120) but the Cancer Group presented a slightly higher mean score (32.2 ± 10.0) than the Control Group (30.0 ± 14.2). Conclusion: Within the limitations of this study, newly diagnosed patients with head and neck cancer and healthy individuals seem to experience similar self-reported dental fear.

RESUMO

BACKGROUND: Community-based violence intervention (CVI) programs are considered important strategies for preventing community violence and promoting health and safety. Mixed and inconclusive results from some prior CVI evaluations, as well as our general lack of understanding about the reasons for such varied findings, may be explained in part by misalignment of program theories of change and evaluation measures. Furthermore, most prior evaluations have focused solely on deficit-based outcomes; this narrow focus is inconsistent with the premise of CVI and may fail to capture improvements in health and well-being that are on the hypothesized pathway from intervention to violence reduction. METHODS: This article describes the process and results of codeveloping a theory of change for community-based youth firearm violence intervention and prevention programs in Washington state through a community-researcher partnership. We followed a multistep iterative process, involving (1) CVI program documentation review, (2) individual meetings, and (3) a day-long workshop. RESULTS: The theory of change included six key domains: (1) root causes, (2) promotive factors, (3) activities, (4) intermediate outcomes, (5) longer-term outcomes, and (6) multilevel context (youth/family, staff/organizational, community, and societal). Root causes were social and structural drivers of community violence. Promotive factors were assets and resources among the community, youth/their families, and community organizations that promote health and safety. Activities were supports and services the program provided to youth and their families, staff, and, potentially, the broader community. Intermediate and longer-term outcomes were the changes among youth, their families, staff, and the community that resulted from program activities. Intermediate outcomes may be felt within 6 months to 1 year, and longer-term outcomes may be felt after 1 to 2 years and beyond. CONCLUSION: The theory of change we codeveloped provides a common lens to conceptualize, compare, and evaluate CVI programs in Washington state and may support more rigorous and equity-centered evaluations. LEVEL OF EVIDENCE: Diagnostic Test/Criteria; Level V.

RESUMO

PURPOSE: Ozone is a potent antioxidant agent which presents an important antimicrobial action and many other biological effects. Although ozone therapy has been widely described and summarized in several other Dentistry areas recently, the studies concerning Dental Implantology have not been systematically compiled and evaluated. Thus, the present study aimed to evaluate the effectiveness of ozone therapy in dental implant procedures. METHODS: MEDLINE (via PUBMED), Cochrane Central Register of Controlled Trials (CENTRAL), and OpenGrey databases were searched (up to, and including, January 23, 2023) for studies in the English language. In addition, the reference lists of the articles were manually examined. Only interventional studies (controlled clinical trials, randomized or not) were considered eligible for inclusion. The risk of bias in each included study was assessed using the Cochrane tool for assessing risk of bias in randomized trials - version 2. RESULTS: 71 potentially eligible records were retrieved but only 5 articles were evaluated and considered eligible for inclusion. Among the studies, 2 addressed clinical situations related to implant insertion, and 3 involved pathological conditions affecting implants in function. Furthermore, only one randomized clinical trial was categorized as low risk of bias. CONCLUSION: The adjuvant use of ozone therapy may positively affect some outcomes in Implant Dentistry, both in treating pathological conditions and conducting rehabilitation (implant installation, secondary implant stability). However, as most studies have a high risk of bias and high heterogeneity, a definitive conclusion cannot be drawn.

RESUMO

Although lipomas are the most common mesenchymal tumors, the intramuscular type is rare. We report the case of a patient with rotator cuff arthropathy with a lipoma in the teres minor. Wide surgical excision and total shoulder arthroplasty with reverse prosthesis was performed and 18 months of follow up showed excellent results with any recurrence. The teres minor is extremely important for the proper function of a reverse prosthesis, and lipoma growth in the muscular belly can compromise the functionality of the prosthesis. To the best of our knowledge, this is the first case report of a rotator cuff arthropathy with a lipoma in the teres minor.

RESUMO

PURPOSE: To assess the impact of different types of anesthesia on the outcomes of arthrocentesis of the TMJ. METHODS: Electronic databases were searched to identify peer-reviewed studies, followed by reference list search and further hand-searching. Randomized clinical trials and controlled studies were considered for inclusion when comparing at least two anesthetic approaches. The risk of bias was assessed using the Cochrane risk of bias tool. RESULTS: Of a total of 506 potentially eligible studies, only a randomized controlled clinical trial and an observational study were included. The former compared some outcomes of arthrocentesis under local and general anesthesia and the latter under sedation and general anesthesia. Moreover, both studies were judged as "high risk of bias." CONCLUSIONS: In general, there appears to be a slight trend toward better outcomes of arthrocentesis for internal TMJ derangements (Wilkes grades I to III) when performed under general anesthesia; however, given that the available evidence is remarkably limited and a high risk of bias was detected within the included studies, a definitive statement cannot be made.

RESUMO

Introduction: Cancer is considered a major public health problem worldwide and may have an important impact on oral health-related quality of life (OHRQoL). Thus, the present study aimed to assess OHRQoL in Brazilian patients aged 3 to 21 years undergoing cancer treatment. Materials and Methods: In total, 121 patients receiving cancer treatment and 363 healthy individuals (control group) were evaluated. OHRQoL was assessed using an age-specific questionnaire, that is, the Brazilian versions of the Early Childhood Oral Health Impact Scale (ECOHIS), the Child Perceptions Questionnaire (CPQ) 11-14-short version, the CPQ 8-10-short version, and the short-form of Oral Health Impact Profile Questionnaire-14 (OHIP-14). Results: Individuals from the control group who were evaluated by the ECOHIS presented more impact on the OHRQoL regarding the psychological and family function score, as well as those evaluated by CPQ 8-10, who presented more impact in general. However, considering CPQ 11-14, cancer patients had their OHRQoL more affected, as shown in both the total questionnaire score and oral symptoms score. Conclusion: Within the limitations of this Brazilian study, cancer treatment seems to be associated with decreased OHRQoL only in patients aged between 11 and 14 years. However, children without cancer aged between 8 and 10 years seem to experience worse OHRQoL.

RESUMO

Introduction: Surgical procedures involving the temporomandibular joint (TMJ) are frequently associated with nerve injuries and subsequent dysfunctions. Considering that traumatic peripheral nerve injuries may resolve slowly and their prognosis is generally unpredictable, the current study aimed to report a clinical case in which both motor (affecting the temporal and zygomatic branches of the facial nerve) and sensory dysfunctions (affecting the auriculotemporal nerve of the trigeminal nerve) following TMJ surgery were effectively treated by using photobiomodulation therapy (PBMT). Case Report: PBMT sessions, involving a total of 30 facial points, were administered twice a week for 10 weeks. The following parameters were utilized: wavelength of 808 nm, energy density of 75 J/cm2, power output of 100 mW, total energy of 3 J, and duration of 30 seconds per point. A considerable improvement in both facial asymmetry and muscle function was achieved within 5 weeks, along with a total restoration of cutaneous sensitivity. By the 10th week of PBMT, the facial movement dysfunction was completely resolved. Conclusion: According to the current case, PMBT seems to be an effective intervention to manage motor and sensory nerve dysfunctions following TMJ surgery.

RESUMO

Although fluoride (F) is required for the normal growth and development of several human organs and tissues, excessive exposure to it may be potentially toxic. Groundwater may present ranging levels of F; however, the appearance, taste, and smell are not altered. Thus, the present study aimed to evaluate dental fluorosis in children from a Brazilian slave-descendent community, as well as to assess F levels in the drinking water supplies available in that area. For that, 21 children aged from 6 to 14 years living in Rincão dos Martimianos were invited to participate. Thylstrup and Fejerskov index (a 0­9 scale) was used to assess dental fluorosis on permanent teeth. Furthermore, the F concentration of two water samples (from the artesian well and a tank) was determined by using a potentiometric method. All children presented dental fluorosis to some degree, ranging from score 2 to 9. About 81% of them had dental fluorosis scores equal to or over 5. Scores lower than 5 were observed only in children younger than 8 years; on the other hand, all children older than 8 years presented scores higher than 5. Moreover, artesian well water had an F concentration of 5 mg/L and tank water 0.8 mg/L. It is suggested that the F-rich groundwater supply was most probably responsible for dental fluorosis in that area. Brazilian slave-descendent communities, therefore, should receive constant attention from their local authorities in order to guarantee a proper water supply for consumption, as well as to provide public health education(AU)


Embora o flúor (F) seja necessário para o crescimento e desenvolvimento normal de vários órgãos e tecidos humanos, a exposição excessiva pode ser potencialmente tóxica. As águas subterrâneas podem apresentar níveis variados de F; no entanto, a aparência, o sabor e o cheiro não são alterados. Desta forma, o presente estudo teve como objetivo avaliar a fluorose dentária em crianças de uma comunidade brasileira descendente de escravos, bem como avaliar os níveis de F na água potável disponível nessa área. Para isso, 21 crianças de 6 a 14 anos residentes no Rincão dos Martimianos foram convidadas a participar da pesquisa. O índice de Thylstrup e Fejerskov (uma escala de 0 a 9) foi usado para avaliar a fluorose dentária em dentes permanentes. Além disso, a concentração de F de duas amostras de água (do poço artesiano e de um tanque) foi determinada pelo método potenciométrico. Todas as crianças apresentaram algum grau de fluorose dentária, variando de 2 a 9. Cerca de 81% delas apresentaram escores de fluorose dentária iguais ou superiores a 5. Escores inferiores a 5 foram observados apenas em crianças menores de 8 anos; por outro lado, todas as crianças maiores de 8 anos apresentaram escores superiores a 5. Além disso, a água do poço artesiano tinha concentração de F de 5 mg/L e a água do tanque 0,8 mg/L. Desta forma, acredita-se que a fonte de água subterrânea rica em F foi provavelmente responsável pela fluorose dentária na região avaliada. As comunidades quilombolas brasileiras, portanto, devem receber atenção constante de suas autoridades locais, a fim de garantir o abastecimento adequado de água para consumo, bem como proporcionar educação em saúde pública(AU)

RESUMO

Many aggressive non-endodontic radiolucent lesions show very similar clinical and radiographical features to periapical lesions of endodontic origin. Since the treatments of endodontic and non-endodontic lesions differ markedly, a precise diagnosis is imperative. Thus, the present study aimed at presenting a clinical case on the diagnosis and management of a Langerhans cell histiocytosis (LCH) lesion mimicking a periapical lesion of endodontic origin. A 51-year-old male patient was referred to a private dental office due to slight pain from the region of tooth 36. Although no sign of prosthetic or endodontic failure was noted, radiographical examination revealed a radiolucent image with poorly defined borders associated with the periapical region of the tooth. Apicoectomy and bone curettage were then performed and, given the clinical and laboratory features, the definitive diagnosis of solitary eosinophilic granuloma was made. The surgical treatment was sufficient for the remission of the symptoms, and recurrence was not observed. Given the current case, dentists should be aware of LCH lesions as they may mimic endodontic periapical pathoses, leading to misdiagnosis and therapeutic complications. Moreover, alveolar bone lesions may be the first or only sign of LCH in many cases.

RESUMO

Introdução: A asma é a doença crônica mais prevalente na infância. O controle da doença é desafiador, porém fundamental para evitar exacerbações graves e danos em longo prazo. Estudos em adultos já mostraram que a baixa adesão medicamentosa, bem como aos cuidados do ambiente, impactam no controle da doença. Objetivo: Conhecer a adesão ao tratamento da asma na população pediátrica e associá-lo ao controle da doença e outras variáveis clínicas. Métodos: Trata-se de um estudo observacional transversal onde foram incluídos 104 pacientes com asma, acompanhados no Serviço de Alergia, Imunologia e Pneumologia Pediátrica do Complexo Hospital de Clínicas da Universidade Federal do Paraná. Foram realizadas entrevistas com base em questionários sobre adesão ao uso de medicação, controle ambiental e crenças populares sobre a asma. Resultados: Foi possível identificar uma correlação positiva entre pacientes que acreditavam em um ou mais mitos sobre a asma e pior adesão ao uso da medicação (p = 0,025). Também foi possível identificar uma relação significativa, entre uma boa adesão à medicação e o controle total da asma (p = 0,038) medido pelo Asthma Control Test (ACT) de 25 pontos. Cinquenta e um por cento dos participantes entrevistados relatou boa e ótima adesão ao controle de ambiente. Conclusão: A adesão e o controle de ambiente avaliados foram satisfatórios na população de crianças asmáticas de um ambulatório de referência. As crenças populares mostraram influência na adesão e no controle da asma dos pacientes entrevistados. Os achados reforçam a importância da comunicação assertiva entre médico e paciente, bem como do papel da educação da asma também voltada para a população pediátrica.


Background: Asthma is the most common chronic disease in childhood. Disease control is challenging but critical to prevent severe exacerbations and long-term damage. Studies in adults have shown that poor adherence to medication and environmental control practices has an impact on disease control. Objective: To determine pediatric asthma treatment adherence and associate it with disease control and other clinical variables. Methods: This was a cross-sectional observational study of 104 patients with asthma followed up at the Pediatric Allergy, Immunology and Pulmonology Service of the Hospital de Clínicas Complex of the Federal University of Paraná, south of Brazil. Participants were interviewed using questionnaires about medication adherence, environmental control, and popular myths about asthma. Results: There was a positive correlation between patients who believed in 1 or more myths about asthma and poorer medication adherence (p=0.025). There was also a significant association between good medication adherence and total asthma control (p=0.038) measured by the 25-point Asthma Control Test. Good and excellent adherence to environmental control practices was reported by 51% of respondents. Conclusion: Medication adherence and environmental control were satisfactory in the population of asthmatic children from a specialized outpatient clinic. Popular beliefs influenced adherence and asthma control in these patients. The findings highlight the importance of assertive communication between physicians and patients, as well as of pediatric asthma education programs.

RESUMO

Neste relato descrevemos as características clínicas, epidemiológicas e radiológicas da pneumonite de hipersensibilidade, uma causa rara de insuficiência respiratória em pediatria. Paciente masculino, com 8 anos de idade, proveniente da zona rural, admitido em serviço terciário por quadro de febre, vômitos, tosse seca, dispneia progressiva, anorexia e perda de peso há 15 dias, associado a taquipneia, esforço respiratório, hipóxia e estertores finos em base direita. Tomografia computadoriza de tórax demonstrou opacidades com atenuações em vidro fosco, com comprometimento difuso e distribuição predominantemente centrolobular e acinar, característicos de pneumonite por hipersensibilidade. Na revisão das condições e hábitos de vida, foi relatado pela responsável do paciente a presença de um aviário e convívio com aves de várias espécies na residência, reforçando a hipótese diagnóstica, após descartadas outras causas de insuficiência respiratória. Iniciado corticoterapia com metilprednisolona 1 mg/ kg/dia por 7 dias, seguido de redução progressiva nas semanas posteriores. Paciente evoluiu com melhora do quadro e alta hospitalar, após orientações sobre controle ambiental e importância do afastamento dos antígenos desencadeantes. A pneumonite por hipersensibilidade é uma síndrome incomum na população pediátrica, que pode levar à insuficiência respiratória e fibrose pulmonar, devendo ser considerada nos pacientes com epidemiologia positiva. Pela sua raridade e semelhança com outras infecções respiratórias, ressalta-se ainda a importância da coleta de dados sobre os hábitos de vida dos pacientes, destacando sua importância para a elucidação diagnóstica.


We report the clinical, epidemiological, and radiological features of hypersensitivity pneumonitis, a rare cause of respiratory failure in pediatrics. An 8-year-old male patient, from a rural area, was admitted to a tertiary care facility for fever, vomiting, dry cough, progressive dyspnea, anorexia, and weight loss for 15 days, associated with tachypnea, respiratory effort, hypoxia, and fine rales at the right base. Chest computed tomography showed ground-glass opacities, diffuse involvement, and predominantly centrilobular and acinar distribution, characteristic of hypersensitivity pneumonitis. In the review of living conditions and habits, the patient's guardian reported the presence of an aviary and interaction with birds of various species in the residence, supporting the presumptive diagnosis of hypersensitivity pneumonitis, after ruling out other causes of respiratory failure. Corticosteroid therapy was started with methylprednisolone 1 mg/kg/day for 7 days, followed by tapering over subsequent weeks. The patient's condition improved, and he was discharged home after receiving guidance on environmental control and the importance of removing the triggering antigens. Hypersensitivity pneumonitis is an uncommon syndrome in the pediatric population. It can lead to respiratory failure and pulmonary fibrosis and should therefore be considered in patients with a positive epidemiological history. Due to its rarity and similarity to other respiratory diseases, collecting data on patients' lifestyle habits is highlighted as an important diagnostic tool.

RESUMO

This systematic review aimed to assess whether the use of autologous platelet concentrates immediately after tooth extraction would prevent ORN in patients treated with radiotherapy (RT) for head and neck cancer (HNC). MEDLINE, Embase, Ovid, Scopus, Web of Science, CENTRAL Cochrane, and OpenGrey databases were searched (up to, and including, June 2021) by two independent reviewers to identify studies, followed by further manual search. As inclusion and exclusion criteria for the studies, only controlled clinical trials (randomized or not) were considered. The risk of bias of each included study was assessed using the Cochrane Risk of Bias Tool. Of the 129 potentially eligible studies, only 2 were included, both randomized controlled clinical trials; however, one used platelet-rich plasma and another leukocyte- and platelet-rich fibrin. Overall, both autologous platelet concentrates had no effect on the outcome assessed. The use of autologous platelet concentrates seems not to be beneficial for ORN prevention following tooth extractions in HNC patients treated with RT; however, according to the available evidence, a reliable statement cannot be made.

RESUMO

A trend within the orthopedic community is rejection of the belief that "one size fits all." Freddie Fu, among others, strived to individualize the treatment of anterior cruciate ligament (ACL) injuries based on the patient's anatomy. Further, during the last two decades, greater emphasis has been placed on improving the outcomes of ACL reconstruction (ACL-R). Accordingly, anatomic tunnel placement is paramount in preventing graft impingement and restoring knee kinematics. Additionally, identification and management of concomitant knee injuries help to re-establish knee kinematics and prevent lower outcomes and registry studies continue to determine which graft yields the best outcomes. The utilization of registry studies has provided several large-scale epidemiologic studies that have bolstered outcomes data, such as avoiding allografts in pediatric populations and incorporating extra-articular stabilizing procedures in younger athletes to prevent re-rupture. In describing the anatomic and biomechanical understanding of the ACL and the resulting improvements in terms of surgical reconstruction, the purpose of this article is to illustrate how basic science advancements have directly led to improvements in clinical outcomes for ACL-injured patients.Level of evidenceV.

RESUMO

Shoulder arthroplasty was first introduced through the developments of Dr. Charles Neer and over the past decade has seen several advancements. Improved recognition and training have heightened the awareness of arthroplasty as a treatment alternative both for surgeons and patients. The addition of reverse shoulder arthroplasty has been the driving force behind the explosive growth of arthroplasty and is now performed more often than anatomic shoulder arthroplasty. Although revision shoulder arthroplasty is primarily of interest to the subspecialist, it is a skill sought by the general orthopaedic surgeon. It is important for the orthopaedic surgeon to be knowledgeable about the planning, necessary skills, and management of basic shoulder arthroplasty.

RESUMO

OBJECTIVE: Radioiodine (131I) is an established modality of definitive treatment of hyperthyroidism. In spite of the vast experience available, there are still several aspects to be clarified, such as whether fixed or calculated doses should be used. The aim of this study was to assess whether efficacy of this treatment could be improved by implementing a simple dosimetric calculation method including ultrasonographic estimation of thyroid volume and a single measurement of 24-hour 131I thyroid uptake. METHODS: A prospective non-inferiority study was designed to compare two procedures to calculate radioiodine activity: the «semi-fixed¼ dose method (A), and the «calculated¼ dose method (B). The first consisted of activity escalation (185MBq steps) based on etiology of hyperthyroidism, 131I uptake, and treatment objective. The second method was based on the «dosimetric compromise¼ concept, considering 24-hour uptake and thyroid volume as the only factors and using a standard half-life of 5.5 days. The target absorbed dose was 150Gy, but after a preliminary analysis (first 100 cases) it was increased to 200Gy in diffuse toxic goiters (DTGs). RESULTS: A total of 212 patients were included. MethodB was at least as effective in terms of final and functional outcome, with a trend to more success and less hypothyroidism. In addition, activities administered were significantly lower. CONCLUSION: In radioiodine therapy of hyperthyroidism, a simple dosimetric method that provided results at least equal to those of a fixed dose-based method, with lower administered activities, could be implemented.

RESUMO

OBJECTIVES: To evaluate the rate of, and reasons for, conversion of closed treatment of humeral shaft fractures using a fracture brace, to surgical intervention. DESIGN: Multicenter, retrospective analysis. SETTING: Nine Level 1 trauma centers across the United States. PATIENTS: A total of 1182 patients with a closed humeral shaft fracture initially managed nonoperatively with a functional brace from 2005 to 2015 were reviewed retrospectively from 9 institutions. INTERVENTION: Functional brace. MAIN OUTCOME MEASUREMENTS: Conversion to surgery. RESULTS: A total of 344 fractures (29%) ultimately underwent surgical intervention. Reasons for conversion included nonunion (60%), malalignment beyond acceptable parameters (24%), inability to tolerate functional bracing (12%), and persistent signs of radial nerve palsy requiring exploration (3.7%). Univariate comparisons showed that females and whites were significantly (P < 0.05) more likely to be converted to surgery. The multivariate logistic regression identified females as being 1.7 times more likely and alcoholics to be 1.4 times more likely to be converted to surgery (P < 0.05). Proximal shaft as well as comminuted, segmental, and butterfly fractures were also linked to a higher rate of conversion. CONCLUSIONS: This large multicenter study identified a 29% surgical conversion rate, with nonunion as the most common reason for surgical intervention after the failure of functional brace. These results are markedly different than previously reported. These results may be helpful in the future when counseling patients on the choice between functional bracing and surgical intervention in managing humeral shaft fractures. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

OBJECTIVE: To determine whether intramedullary nail (IMN) diameter, antegrade versus retrograde insertion, or the difference between the canal and IMN diameter affect femoral shaft fracture healing. DESIGN: Retrospective analysis of a prospective database. SETTING: Level One Regional Trauma Center. PATIENTS/PARTICIPANTS: Seven hundred thirty-three femoral shaft fractures (OTA/AO 32) treated with an IMN between 1999 and 2017. After exclusion criteria, 484 fractures remained in the final analysis. INTERVENTION: Closed section, cannulated, interlocked, titanium alloy IMN using a reamed insertion technique. MAIN OUTCOME MEASUREMENTS: Nonunion, IMN size (10, 11.5, and 13 mm), antegrade versus retrograde insertion, Δ canal-nail diameter (ΔD) after reaming (<1, 1-2, or >2 mm). RESULTS: IMN diameters used were as follows: 314/10 mm (64%), 137/11.5 mm (28%), and 33/13 mm (8%). Forty-five percent were placed in antegrade versus 55% retrograde. Four hundred fifty-six fractures (94.2%) healed uneventfully. There were no IMN failures. 10/484 IMNs (2%) had broken interlocking screws; only 4 were associated with a NU. Average time to union was 23 weeks (12-119). Twenty-eight (5.8%) developed NU. There was no statistical correlation between (1) the NU rate and IMN diameter: 10 mm, 6.3%; 11.5 mm, 5.1%; 13 mm, 3% (P = 0.8, power = 0.85), (2) the NU rate and ΔD: 7.1% <1 mm, 5.6% 1-2 mm, 20% >2 mm (P = 0.36), (3) the NU rate and fracture location: Prox = 11%, Mid = 5%, Dist = 3% (P = 0.13), or (4) the NU rate and antegrade (7.2%) versus retrograde (4.2%) insertion (P = 0.24). CONCLUSION: Similar healing rates occurred regardless of IMN diameter, Δ canal-nail diameter after reaming, or insertion site. This indicates that a closed section, cannulated, interlocked, titanium alloy IMN with a diameter of 10 mm can be considered the standard diameter for the treatment of acute femoral shaft fractures, regardless of entry point. This should be associated with less reaming and therefore shorter operative times, and possibly less hospital implant inventories as well. Larger diameter IMN should be reserved for revision surgery.

RESUMO

Abstract Case report: A 50-year-old female patient with an 8-year history of amass in the right breast which has undergone rapid progressive growth, involving the entire breast, over the past 7 months, diagnosed as a phyllodes tumor. Simple right mastectomy with axillary lymph node dissection and pectoralis major fascia resection were performed under general anesthesia. Ultrasound-guided erector spinae plane block was performed for postoperative analgesia, with excellent response up to 18hours following the procedure, and no need for additional opioids. There were no adverse effects or complications associated with the block. Conclusions: Ultrasound-guided erector spinae block is a fast and safe procedure that may be used as a valuable adjunct to ensure postoperative analgesia in radical mastectomy cases, which pose a challenge in terms of pain control. Moreover, it offers an advantage in terms of reduced opioid requirement in these patients.


Resumen Caso clínico: Se presenta el caso de una paciente de 50 años con cuadro clínico de 8 años de evolución de masa en mama derecha la cual en los últimos 7 meses muestra un crecimiento rápido y progresivo que ocupa toda la mama, hacen diagnóstico de tumor phylloides. Realizan mastectomía derecha simple más vaciamiento ganglionar axilary resección de fascia pectoral mayor bajo anestesia general. Se efectúa bloqueo del elevador de la espina guiado por ultrasonido con fines analgésicos en el posoperatorio, obteniéndose una excelente respuesta hasta 18 horas posterior al procedimiento, sin necesidad de consumo de opioides, no se registraron efectos adversos o complicaciones relacionadas con el bloqueo. Conclusiones: El bloqueo del elevador de la espina ecoguiado es un procedimiento rápido y seguro que puede ser una herramienta valiosa para asegurar la analgesia posoperatoria en mastectomías radicales que generan un desafío en control del dolor, además de la ventaja de disminución de consumo de opioides en estas pacientes.

RESUMO

OBJECTIVES: To determine whether a difference in plate position for fixation of acute, displaced, midshaft clavicle fractures would affect the rate of secondary intervention. DESIGN: Retrospective Comparative Study. SETTING: Two academic Level 1 Regional Trauma Centers. PATIENTS: Five hundred ten patients treated surgically for an acutely displaced midshaft clavicle fracture between 2000 and 2013 were identified and reviewed retrospectively at a minimum of 24 months follow-up (F/U). Fractures were divided into 2 cohorts, according to plate position: Anterior-Inferior (AI) or Superior (S). Exclusion criteria included age <16 years, incomplete data records, and loss to F/U. Group analysis included demographics (age, sex, body mass index), fracture characteristics (mechanism of injury, open or closed), hand dominance, ipsilateral injuries, time between injury to surgery, time to radiographic union, length of F/U, and frequency of secondary procedures. INTERVENTION: Patients were treated either with AI or S clavicle plating at the treating surgeon's discretion. MAIN OUTCOME MEASURES: Rate and reason for secondary intervention. STATISTICAL ANALYSIS: Fisher exact test, t test. and odds ratio were used for statistical analysis. RESULTS: Final analysis included 252 fractures/251 patients. One hundred eighteen (47%) were in group AI; 134 (53%) were in group S. No differences in demographics, fracture characteristics, time to surgery, time to union, or length of F/U existed between groups. Seven patients/7 fractures (5.9%) in Group AI underwent a secondary surgery whereas 30 patients/30 fractures (22.3%) in group S required a secondary surgery. An additional intervention secondary to superior plate placement was highly statistically significant (P < 0.001). Furthermore, because 80% of these subsequent interventions were a result of plate irritation with patient discomfort, the odds ratio for a second procedure was 5 times greater in those fractures treated with a superior plate. CONCLUSIONS: This comparative analysis indicates that AI plating of midshaft clavicle fractures seems to lessen clinical irritation and results in significantly fewer secondary interventions. Considering patient satisfaction and a reduced financial burden to the health care system, we recommend routine AI plate application when open reduction internal fixation of the clavicle is indicated. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
