RESUMO
Introduction: The inability of the spinal cord to propagate sensory and motor stimuli as a result of the disruption of the nerve tracts is called spinal cord injury. Objective: This study analyzes clinically and radiologically the hands and wrists of spinal cord injured patients, evaluating their motor and sensitive functionality, in order to determine if these patients are more likely to develop degenerative alterations. Methods: 14 patients (8 paraplegics and 6 tetraplegics) were evaluated, undergoing anamnesis and clinical examination - a scale of muscular strength (MRC - Medical Research Council) and the amplitude measurement of the movement with a manual goniometer (ROM), were used for objective evaluation - and x-ray exams. The results were compared with pre-existing data from other studies. Results: When asked, only one of the 14 observed patients complained about constant wrist pain, described as level 3 (weak to moderate), based on the visual analog scale (VAS). The motor evaluation, MRC and ROM divided the group of patients into two subgroups: paraplegic and tetraplegic patients. The x-ray analysis showed, based on Kellgren and Lawrence classification, that all exam images fit grades 1 or 2 of osteoarthritis and osteoarthrosis. Conclusion: In conclusion, spinal cord injured patients showed none or minimal clinical and radiological signs of osteoarthritis on hands or wrists. Overall, the hands and wrists of spinal cord-injured patients behave similarly to noninjured patients. Level of Evidence III; Retrospective Comparative Study.
Introdução: A incapacidade da medula espinhal de propagar estímulos sensoriais e motores como resultado do rompimento das vias nervosas é chamada de lesão da medula espinhal. Objetivo: Este estudo analisa clínica e radiograficamente mão e punhos de pacientes lesados medulares, avaliando função motora e sensitiva, a fim de determinar se estes pacientes estariam mais propensos a alterações degenerativas. Métodos: 14 pacientes (8 paraplégicos e 6 tetraplégicos) foram avaliados, passando por anamnese e exame clínico - sendo escala de força muscular (MRC - Medical Research Council) e a medição da amplitude de movimento com um goniômetro manual (ROM) foram utilizados para análise objetiva - e radiografias. Os dados obtidos foram comparados com literatura preexistente. Resultados: Quando questionados, apenas um dos 14 pacientes observados referiu dor crônica nos punhos, descrita como nível 3 (fraca a moderada), baseada na escala visual analógica. A avaliação motora, MRC e ROM dividiram os pacientes em 2 subgrupos: pacientes paraplégicos e tetraplégicos. A análise radiográfica mostrou, baseada na classificação de Kellgren e Lawrence, que todas as imagens se encaixam nos graus 1 ou 2 de osteoartrite e osteoartrose. Conclusão: Conclui-se, então, que pacientes lesados medulares apresentam nenhuma ou mínimas alterações clínicas e radiológicas para osteoartrite ou osteoartrose de punhos ou mãos. Ou seja, no geral, mãos e punhos de pacientes lesados medulares comportam-se como os pacientes sem lesão medular. Nível de Evidência III; Estudo Retrospectivo Comparativo.
RESUMO
OBJECTIVE: To describe and analyze the aspects regarding the cost and length of stay for elderly patients with bone fractures in a tertiary reference hospital. METHODS: A cross-sectional retrospective study using data obtained from medical records between January and December 2020. For statistical analysis, exploratory analyses, Shapiro-Wilk test, χ2 test, and Spearman correlation were used. RESULTS: During the study period, 156 elderly patients (62.2% women) with bone fractures were treated. The main trauma mechanism was a fall from a standing height (76.9%). The most common type of fracture in this sample was a transtrochanteric fracture of the femur, accounting for 40.4% of cases. The mean length of stay was 5.25 days. The total cost varied between R$2,006.53 and R$106,912.74 (average of R$15,695.76) (updated values). The mean daily cost of hospitalization was R$4,478.64. A positive correlation was found between the length of stay and total cost. No significant difference in cost was observed between the two main types of treated fractures. CONCLUSION: Fractures in the elderly are frequent, resulting in significant costs. The longer the hospital stay for treatment, the higher the total cost. No correlation was found between total cost and number of comorbidities, number of medications used, and the comparison between the treatment of transtrochanteric and femoral neck fractures.

BACKGROUND: Peptide drugs are advantageous because they are subject to rational design and exhibit highly diverse structures and broad biological activities. The NS2B-NS3 protein is a particularly promising flavivirus therapeutic target, with extensive research on the development of inhibitors as therapeutic candidates, and was used as a model in this work to determine the mechanism by which GA-Hecate inhibits ZIKV replication. OBJECTIVE: The present study aimed to evaluate the potential of GA-Hecate, a new antiviral developed by our group, against the Brazilian Zika virus and to evaluate the mechanism of action of this compound on the flavivirus NS2B-NS3 protein. METHODS: Solid-phase peptide Synthesis, High-Performance Liquid Chromatography, and Mass Spectrometry were used to obtain, purify, and characterize the synthesized compound. Real-time and enzymatic assays were used to determine the antiviral potential of GA-Hecate against ZIKV. RESULTS: The RT-qPCR results showed that GA-Hecate decreased the number of ZIKV RNA copies in the virucidal, pre-treatment, and post-entry assays, with 5- to 6-fold fewer RNA copies at the higher nontoxic concentration in Vero cells (HNTC: 10 µM) than in the control cells. Enzymatic and kinetic assays indicated that GA-Hecate acts as a competitive ZIKV NS2B-NS3 protease inhibitor with an IC50 of 32 nM and has activity against the yellow fever virus protease. CONCLUSION: The results highlight the antiviral potential of the GA-Hecate bioconjugate and open the door for the development of new antivirals.
RESUMO
HIV-1 antiretroviral therapy is highly effective but fails to eliminate a reservoir of latent proviruses, leading to a requirement for life-long treatment. How the site of integration of authentic intact latent proviruses might impact their own or neighboring gene expression or reservoir dynamics is poorly understood. Here, we report on proviral and neighboring gene transcription at sites of intact latent HIV-1 integration in cultured T cells obtained directly from people living with HIV, as well as engineered primary T cells and cell lines. Proviral gene expression was correlated to the level of endogenous gene expression under resting but not activated conditions. Notably, latent proviral promoters were 100-10,000× less active than in productively infected cells and had little or no measurable impact on neighboring gene expression under resting or activated conditions. Thus, the site of integration has a dominant effect on the transcriptional activity of intact HIV-1 proviruses in the latent reservoir, thereby influencing cytopathic effects and proviral immune evasion.

RESUMO
BACKGROUND: Chikungunya virus (CHIKV) has spread across Brazil with varying incidence rates depending on the affected areas. Due to cocirculation of arboviruses and overlapping disease symptoms, CHIKV infection may be underdiagnosed. To understand the lack of CHIKV epidemics in São José do Rio Preto (SJdRP), São Paulo (SP), Brazil, we evaluated viral circulation by investigating anti-CHIKV IgG seroconversion in a prospective study of asymptomatic individuals and detecting anti-CHIKV IgM in individuals suspected of dengue infection, as well as CHIKV presence in Aedes mosquitoes. The opportunity to assess two different groups (symptomatic and asymptomatic) exposed at the same geographic region aimed to broaden the possibility of identifying the viral circulation, which had been previously considered absent. METHODOLOGY/PRINCIPAL FINDINGS: Based on a prospective population study model and demographic characteristics (sex and age), we analyzed the anti-CHIKV IgG seroconversion rate in 341 subjects by ELISA over four years. The seroprevalence increased from 0.35% in the first year to 2.3% after 3 years of follow-up. Additionally, we investigated 497 samples from a blood panel collected from dengue-suspected individuals during the 2019 dengue outbreak in SJdRP. In total, 4.4% were positive for anti-CHIKV IgM, and 8.6% were positive for IgG. To exclude alphavirus cross-reactivity, we evaluated the presence of anti-Mayaro virus (MAYV) IgG by ELISA, and the positivity rate was 0.3% in the population study and 0.8% in the blood panel samples. In CHIKV and MAYV plaque reduction neutralization tests (PRNTs), the positivity rate for CHIKV-neutralizing antibodies in these ELISA-positive samples was 46.7%, while no MAYV-neutralizing antibodies were detected. Genomic sequencing and phylogenetic analysis revealed CHIKV genotype ECSA in São José do Rio Preto, SP. Finally, mosquitoes collected to complement human surveillance revealed CHIKV positivity of 2.76% of A. aegypti and 9.09% of A. albopictus (although it was far less abundant than A. aegypti) by RT-qPCR. CONCLUSIONS/SIGNIFICANCE: Our data suggest cryptic CHIKV circulation in SJdRP detected by continual active surveillance. These low levels, but increasing, of viral circulation highlight the possibility of CHIKV outbreaks, as there is a large naïve population. Improved knowledge of the epidemiological situation might aid in outbreaks prevention.

RESUMO
ABSTRACT Objective: This study aimed to analyze the relationship between the number of motorcycle accidents attended at a reference Hospital for trauma in Campinas, state of São Paulo, and the pandemic by COVID-19 during the year 2020. Methods: This is a cross-sectional, descriptive retrospective study carried out at Hospital PUC- Campinas, through the analysis of medical records of patients, victims of motorcycle trauma undergoing orthopedic surgical management in 2020. The phases of the pandemic and the isolation rates according to the São Paulo Plan were studied. Chi-Square tests, and the Least Squares method were applied for statistical calculations. Results: 155 medical records were analyzed, of which 91.61% of the patients were male. Of those admitted, 94.84% suffered fractures and 51.61%, polyfractures. There was a correlation between the average isolation rates and the number of accidents. In the 14-day period, as the average isolation rate increased by 10%, there was an increase of approximately 3 accidents in that period. In the 7-day analysis, 1.7 more traumas were observed for every 10% increase in the average isolation. Conclusion: The results suggest that by increasing the average isolation rate, the number of traumas per motorcycle treated at the institution increased. Level of Evidence III, Comparative Retrospective Study.

RESUMO
ABSTRACT The chronic hepatitis C (CHC) treatment is currently based on the use of direct-acting antivirals (DAAs), and patients infected with hepatitis C virus genotype 3 (GT3) have emerged as a more difficult-to-cure population. The NS5A inhibitor daclatasvir (DCV) and sofosbuvir (SOF), an NS5B viral polymerase inhibitor, are among the drugs that compose more effective and safer treatment regimens. The virus genetic variability is related to resistance-associated substitutions (RASs) that adversely impact DAAs effectiveness. The aims of this study were to analyze the association of NS5A and NS5B RASs and other clinical factors with DAAs regimens effectiveness in patients with GT3 CHC infection. This was a prospective cohort study performed in a Brazilian university hospital. Individuals older than 18 years with GT3 CHC treated with SOF + DCV ± ribavirin (RBV) or SOF + peginterferon (PEG) + RBV were included. Blood samples were collected at baseline and post-treatment. A total of 121 patients were included. Sustained virological response rates were 87.6% for the SOF + DCV ± RBV group and 80.0% for the SOF + PEG + RBV arm. Cirrhosis, prior treatment with interferon/PEG + RBV, and baseline NS5A RAS were associated with higher risk of treatment failure. The NS5A analysis suggested that A30K, Y93H, and RAS at site 62 were related to failure. Interestingly, a likely compensatory effect was shown between A30K and A62T. Emergence of Y93H was always associated with RAS at position 62. The RASs dynamics comprehension is an important tool to indicate more effective treatment for GT3 patients.
RESUMO
ABSTRACT Objective: To evaluate the epidemiological profile of motorcycle accident victims in a metropolis with more than one million inhabitants attended in a university hospital of reference in 2017. Methods: a retrospective study through the analysis of medical records of 105 motorcycle accident victims in Campinas (SP) attended in a university hospital of reference and who needed surgical procedure in 2017. Results: 87 patients (82.9%) were men. Multiple fractures were observed in 61 patients (58.1%) and polytrauma was found in 14 patients (13.3%). Tibial fracture was the most frequent, present in 65 cases (61.9%). Exposed fractures occurred in 68 patients (64.7%). Among the polytrauma victims, the most frequent injury was traumatic brain injury (TBI), present in seven patients (6.6%). The mean age was 29.8 years (range 6-63 years). The average length of hospital stay was 14 days (1-87). Conclusion: It is essential to investigate and evaluate the victims' epidemiological profile, as well as the resulting injuries, in order to provide adequate support for the implementation of measures aimed at primary prevention and awareness of the most affected groups.

RESUMO
ABSTRACT Objective: To evaluate the socioeconomic impact of motorcycle accidents of a metropolis with one million inhabitants treated by a university hospital in 2017. To study hospital cost and time of victims, evaluate definite and incapacitating sequelae, and analyze patient's insertion in the labor market six months after the accident. Methods: Retrospective study of 62 victims of motorcycle accidents treated in the emergency room and referred for surgical procedure in a university hospital. Data were collected from medical records and answers via telephone six months after the trauma. Results: Injuries related to motorcycle accident resulted in high hospital costs. Average loss per patient was R$ 17,555. Of those who answered the functional impact questionnaire, 64% were on paid leave by INSS and 84% presented partial or permanent physical disabilities after the accident. Only 9 people (36%) received any kind of financial benefit from public authorities. Conclusion: High costs are directly related to hospitalization time and surgical needs. Most victims needed financial help and had their social lives aggravated. Investments in motorcyclists' awareness of traffic laws and use of safety equipment are needed, as well as in road infrastructure. Level of evidence II, Prognostic studies.
RESUMO Objetivo: Avaliar o impacto socioeconômico de acidentes motociclísticos de uma metrópole com mais de um milhão de habitantes atendidos, no ano de 2017, em um hospital universitário. Estudar custo e tempo de internação hospitalar das vítimas, avaliar sequelas definitivas e incapacitantes e analisar a inserção no mercado de trabalho seis meses depois do acidente. Métodos: Estudo retrospectivo de 62 pacientes vítimas de acidentes motociclísticos, atendidos na urgência e emergência, levados para procedimento cirúrgico de um hospital universitário. Coleta de dados através do levantamento de prontuários e contato telefônico seis meses após o trauma. Resultados: Lesões relacionadas às vítimas implicaram elevados custos hospitalares. Prejuízo médio por paciente foi de R$ 17.555. Dos que responderam ao questionário do impacto funcional, 64% ficaram afastados da atividade laboral pelo INSS e 84% apresentaram incapacidades físicas parciais ou permanentes após o acidente. Apenas 9 (36%) receberam algum tipo de benefício financeiro do governo. Conclusão: Elevados custos estão diretamente relacionados ao tempo de internação e necessidades cirúrgicas. A maioria das vítimas necessitou de auxílio financeiro e teve sua vida social prejudicada. Investimentos em conscientização dos motociclistas, para que conduzissem respeitando as leis de trânsito e utilizando equipamentos de segurança, e na infraestrutura das rodovias são necessários.

RESUMO
ABSTRACT Objective: This article aimed to evaluate the efficacy of arthroereisis using synthetic polyethylene implants to correct excessive valgus deformity in pediatric patients with flexible valgus flatfoot. Methods: Retrospective study of 20 pediatric patients with flexible valgus flatfoot, totaling 23 feet, between five and 14 years old, operated between January 2009 and July 2016. Clinical evaluations were performed by the Valenti podoscopic classification and the American Orthopaedic Foot & Ankle Society criteria, based on radiographic images and podoscopic analysis. These patients underwent surgical treatment with the introduction of a synthetic implant in the sinus tarsi. Multiple linear regression analysis with Backward selection of variables, angles of pre and postoperative of radiographic images of the patients submitted to arthroereisis were performed. Results: The arthroereisis with interposition of synthetic material was satisfactory, considering that 91% of the cases presented clinical and radiographic improvement, with correction of angles and improvement in deformity degrees. Two cases presented implant loosening. The variables of the Bordelon and Pitch angles significantly influenced (p < 0,05) the improvement of the correction of deformity degrees. Conclusion: The arthroereisis with the interposition of synthetic polyethylene material showed to be an effective technique for flexible flatfoot in symptomatic pediatric patients.

RESUMO
Objetivo Avaliar a etiologia das tendinopatias e as diferentes técnicas cirúrgicas utilizadas na reparação dos tendões calcâneos, tibial posterior, tibial anterior, fi bular curto e fi bular longo e apresentar os resultados clínico-funcionais, grau de satisfação dos pacientes e as complicações pós-cirúrgicas. Métodos Estudo retrospectivo de 88 pacientes com lesões degenerativas ou agudas dos tendões calcâneo, tibial anterior, tibial posterior, fi bular curto e fi bular longo, entre o período de 2005 a 2017. Resultados Dos 88 pacientes analisados, 50 eram do sexo masculino e 38 do sexo feminino, com idade média de 49 anos. A frequência de lesão foi de 54% para o membro direito, 40% para o membro esquerdo e 6% para ambos os pés. O mecanismo de ruptura predominante foi o degenerativo, em 56% dos pacientes. A maioria dos indivíduos (49%) apresentou lesões no tendão calcâneo e a técnica cirúrgica com a utilização do tendão semitendíneo foi empregada na maioria dos casos (41%). Os resultados clínicos funcionais obtidos pelo Questionário da American Orthopaedic Foot and Ankle Society no pós-operatório, após um tempo médio de 18 meses, foram de 87 pontos (variando de 65 a 92). Houve complicação na área receptora em apenas 5 pacientes. Conclusão O reparo cirúrgico das tendinopatias mostrou-se extremamente efetivo na reabilitação funcional dos pacientes, com uma baixa taxa de complicações e elevado grau de satisfação dos pacientes.
Objective To evaluate the etiology of tendinopathies and the different surgical techniques used to repair the calcaneus, posterior tibial, anterior tibial, long fibular and short fibular tendons and present the clinical-functional results, the degree of patient satisfaction and postoperative complications. Methods A retrospective study of 88 patients with degenerative or acute lesions of the calcaneus, anterior tibial, posterior tibial, short fibular and long fibular tendons between 2005 and 2017. Results Of the 88 patients analyzed, 50 were males and 38 female, with a mean age of 49 years. The lesion frequency was 54% for the right limb, 40% for the left limb and 6% for both feet. The predominant mechanism of rupture was degenerative in 56% of the patients. Most of the individuals (49%) presented lesions in the calcaneus tendon and the semitendinosus tendon surgical technique was used in most cases (41%). The functional clinical results obtained by the American Orthopedic Foot & Ankle Society Questionnaire postoperative questionnaire after an average time of 18 months, were 87 points (ranging from 65 to 92). Recipient area complications were reported in only 5 patients. Conclusion Tendinopathy surgery proved to be extremely effective in the functional rehabilitation of patients, with a low rate of complications and a high degree of patient satisfaction.

ABSTRACT OBJECTIVES: To analyze and evaluate functional and clinical results in patients with congenital clubfoot treated with Ponseti's technique. METHODS: This study evaluated 31 patients diagnosed with 51 congenital clubfeet, treated between April 2006 and September 2011 with Ponseti's technique. The patients who did not achieve an equinus correction with manipulation were treated with Achilles tenotomy. An anterior tibial tendon transfer was performed in patients who maintained residual adduction. All plasters were made by fellows and supervised by Ankle and Foot Chiefs. The technique was performed without the need for physical therapists, orthotics, and plaster technicians. Patients were submitted to pre- and post-treatment examination and evaluated under Pirani's classification. RESULTS: Male patients had an increased incidence and the right side was more affected, while bilateral involvement was observed in 64.5% of the cases. The mean number of cast changes was 5.8, and Achilles tenotomy was necessary in 26 patients. There were significant deformity improvements in 46 of the 51 treated feet (90.2%); Pirani's mean score improved from 5.5 to 3.6 after treatment. CONCLUSION: The Ponseti method was effective in both functional and clinical evaluation of patients, with significant statistical relevance (p = 0.0001), with a success rate of 90.2% and mean improvement in the Pirani's index of 65.5%.
RESUMO OBJETIVOS: Analisar e avaliar os resultados funcionais e clínicos em pacientes com pé torto congênito tratados pela técnica de Ponseti. MÉTODOS: O estudo incluiu 31 pacientes diagnosticados com 51 pés tortos congênitos, tratados entre abril de 2006 a setembro de 2011 pela técnica de Ponseti. Os pacientes que não alcançaram a correção do estado equino com manipulação foram tratados com tenotomia do Aquiles. Uma transposição do tendão tibial anterior foi feita nos pacientes que mantiveram uma adução residual. Todos os gessos foram feitos por residentes e supervisionados pelos chefes de Tornozelo e Pé. A técnica foi aplicada sem a necessidade de fisioterapeutas ou técnicos de gesso. Os pacientes foram submetidos a exame antes e depois do tratamento e avaliados de acordo com a escala de Pirani. RESULTADOS: Os pacientes do sexo masculino apresentaram um aumento de incidência e o lado direito foi o mais afetado, enquanto que o acometimento bilateral foi observado em 64,5% dos casos. A média de mudanças de gesso foi de 5,8 e a tenotomia do tendão de Aquiles foi necessária em 26 pacientes. Houve melhorias significativas das deformidades em 46 dos 51 dos pés tratados (90,2%), a escala de Pirani pontuou um avanço na média de 5,5 para 3,6 após o tratamento. CONCLUSÃO: O método de Ponseti foi eficaz nas avaliações funcionais e clínicas dos pacientes, com uma relevância estatística significante (p = 0,0001), com uma taxa de sucesso de 90,2% e um avanço na escala de Pirani de 65,5%.

To evaluate, compare and identify the surgical technique with best results for treating intra-articular calcaneal fractures, taking into account postoperative outcomes, complications and scoring in the Aofas questionnaire. METHODS: This was a retrospective study on 54 patients with fractures of the calcaneus who underwent surgery between 2002 and 2012 by means of the following techniques: (1) open reduction with extended L-shaped lateral incision and fixation with double-H plate of 3.5 mm; (2) open reduction with minimal incision lateral approach and percutaneous fixation with wires and screws; and (3) open reduction with minimal incision lateral approach and fixation with adjustable monoplanar external fixator. RESULTS: Patients treated using a lateral approach, with fixation using a plate had a mean Aofas score of 76 points; those treated through a minimal incision lateral approach with screw and wire fixation had a mean score of 71 points; and those treated through a minimal incision lateral approach with an external fixator had a mean score of 75 points. The three surgical techniques were shown to be effective for treating intra-articular calcaneal fractures, without any evidence that any of the techniques being superior. CONCLUSION: Intra-articular calcaneal fractures are complex and their treatment should be individualized based on patient characteristics, type of fracture and the surgeon's experience with the surgical technique chosen.

OBJETIVO: Identificar técnica cirúrgica com melhor resultado para tratamento de fraturas intra-articulares do calcâneo tipo Sanders II e III. MÉTODOS: Revisão sistemática da literatura de estudos clínicos randomizados comparativos de cirurgias de fraturas intra-articulares do calcâneo Sanders II e III, avaliados pelo questionário da American Orthopaedic Foot and Ankle Society (AOFAS). Os estudos foram identificados e recuperados nas bases de dados LILACS, MEDLINE/Pubmed, Biblioteca Cochrane, SciELO, Embase, Science Direct, Scopus, Journals@Ovid, ISI Web of Knowledge, Evidence Based Medicine, além de consulta às referências dos estudos acessados. RESULTADOS: foram identificados três trabalhos randomizados avaliando três técnicas cirúrgicas: fixador externo, fixação percutânea com fio de Kirschner e fixação com parafuso canulado. Todas as técnicas compararam tratamento com redução aberta e fixação com placa e parafuso. Obteve-se as seguintes médias (AOFAS): 86,23 (placa e parafuso), 88,2 (fixação externa), 90,6 (fixação percutânea com fio de Kirschner) e 87,2 (fixação com parafuso canulado). CONCLUSÃO: fixação percutânea com fio de Kirschner apresentou melhores resultados e menor número de complicações, porém as evidências são insuficientes para afirmar superioridade desse tratamento em relação a outras técnicas cirúrgicas.
OBJECTIVE: This paper aims to identify the most effective surgical technique for intraarticular calcaneal fractures of Sanders' types II and III.METHODS: Systematic review of comparative randomized clinical trials on surgical treatment of the intraarticular fractures of the calcaneus (Sanders types II and III) that used the questionnaire of the American Orthopaedic Foot and Ankle Society. The studies were identified and retrieved in the following databases - LILACS, MEDLINE/PubMed, Cochrane Library, SciELO, EMBASE, Science Direct, Scopus, Journals@Ovid, ISI Web of Knowledge, Evidence Based Medicine, besides consulting the references of studies accessed. The keywords used Boolean logic (AND and OR): "calcaneus fracture, calcaneous, calcaneal; surgical treatment, management; open reduction, minimally invasive, percutaneous reduction; internal fixation, external fixation. RESULTS: We identified only three randomized comparative trials. Each study compared a different technique (external fixation, percutaneous fixation with Kirchner wires and cannulated screws fixation) to the open reduction with internal fixation using plate and screws (considered the standard technique).CONCLUSION: Comparing the series, percutaneous fixation using Kirschner wires presented the best results, however, evidence is insufficient to assert superiority of this treatment in comparison with other surgical techniques.
