RESUMO

INTRODUCTION: The low attendance of families in child developmental follow-up programs for at-risk preterm children is a challenge in Brazil. OBJECTIVE: This study evaluates the feasibility of implementing a developmental follow-up program for Brazilian preterm infants in a hybrid format. METHODS: This is an observational, prospective cohort study, involving preterm infants. Longitudinal developmental test results, the participation frequency in the program, and the number of referrals to early intervention programs were used to assess feasibility. The General Movements (GMs) assessment, Alberta Infant Motor Scale (AIMS) and, Survey of Wellbeing of Young Children (SWYC) Milestones were administered via telehealth. The Bayley-III was administered in-person. RESULTS: Thirty-four preterm infants attended the follow-up until 12 months of corrected age and 18 (52.9 %) concluded all follow-up assessments. Twenty-six (76.5 %) attended all assessments via telehealth, and 26 (76.5 %) attended the in-person assessment. Eighteen (52.9 %) infants showed at least one altered result in development tests. Infants exhibiting abnormal results in the GMs assessment, motor developmental delay according to the AIMS, or developmental delay based on Balley-III were promptly referred to early intervention services. CONCLUSION: This study demonstrated high participation rate and low dropout in a developmental follow-up program employing a hybrid format. The substantial number of identified infants with developmental delay emphasizes the importance of timely detection of motor delays to referral to early intervention services.

RESUMO

This quasi-experimental study investigated the preliminary effects of a structured education intervention in a pooled sample of cardiovascular rehabilitation (CR) patients in Brazil. Recently enrolled (RE) and long-term enrolled (LTE) patients attended 12 weekly education sessions in addition to three weekly exercise sessions. Patients completed surveys assessing disease-related knowledge, physical activity, food intake, self-efficacy, and health literacy. Functional capacity was assessed by the 6-minutes walking test. All outcomes were assessed at pre-,post-CR, and 6-months follow-up. Bonferroni correction was applied. In total, 69 (69.7%) patients completed all three assessments. There were significant improvements in knowledge pre-to post-test in both subgroups (p < 0.001), and in functional capacity (p ≤ 0.001) and food intake (p ≤ 0.001) pre-to post-test in the RE subgroup. Post-test knowledge was correlated to physical activity, functional capacity and health literacy. This preliminary study suggests the importance of structured education for CR patients. A larger study using a randomized controlled design is needed to determine efficacy.

En el PP, el 47 % (32) de los pacientes tuvieron exacerbaciones graves vs. el 32 % (22) de los pacientes en el PV (p 0,048). Hubo 91 exacerbaciones graves en el PP vs. 49 en el PV (p 0,029), reducción del 46 %. No hubo diferencias en las hospitalizaciones (PP 10, PV 6; p 0,9). La telemedicina fue efectiva para el seguimiento de pacientes con asma grave

During the COVID-19 pandemic, health care strategies were explored to ensure the follow-up of children with severe asthma. This was a prospective, observational, and comparative study. Patients in the severe asthma program of a tertiary care children's hospital were included (n: 74). The extent of control, exacerbations, and hospitalizations during an in-person period (IPP) (March 2019­2020) and an online period (OP) (April 2020­2021) was assessed. A total of 74 patients were enrolled in the IPP compared to 68 (92%) in the OP. During the IPP, 68% (46) of patients had exacerbations versus 46% (31) during the OP (p = 0.003). During the IPP, 135 total exacerbations were recorded compared to 79 during the OP (p = 0.001); this accounted for a 41% reduction. During the IPP, 47% (32) of patients had severe exacerbations versus 32% (22) during the OP (p = 0.048). A total of 91 severe exacerbations were recorded during the IPP compared to 49 during the OP (p = 0.029); the reduction was 46%. No differences were observed in terms of hospitalization (IPP: 10, OP: 6; p = 0,9). Telemedicine was effective for the follow-up of patients with severe asthma.

RESUMO

Introducción: El virus chikungunya (CHIKV) causa una enfermedad con manifestaciones agudas bien documentadas, pero existen pocos datos sobre la persistencia de síntomas y secuelas a largo plazo. Objetivos: Evaluar la persistencia de signos, síntomas y factores asociados en pacientes con infección por CHIKV en un seguimiento de 6 meses posinfección. Materiales y métodos: Estudio de cohorte ambispectivo que incluyó casos confirmados de CHIKV notificados en abril de 2023 en Coronel Oviedo, Paraguay. Se realizaron entrevistas al mes, a los tres meses y a los 6 meses posinfección. Se analizaron características demográficas, comorbilidades, manifestaciones reumáticas y sintomáticas. Resultados: Ingresaron 333 participantes, completando seguimiento a 6 meses 170 pacientes. A los 6 meses persistieron: dolor de espalda (61.2%), artritis (57.1%), cefalea (54.1%), fatiga (51.2%), mialgia (49.4%), debilidad (47.6%), depresión (45.9%) y artralgia (45.9%). La persistencia de artritis (OR 7.54; p=0.008) y mialgia (OR 3.24; p=0.031) a 6 meses fue mayor en el grupo de 36-45 años. Conclusiones: Alta persistencia de síntomas musculoesqueléticos y fatiga hasta 6 meses posinfección, con tendencia decreciente, pero exacerbación de depresión. Edad entre 36-45 años asociada a mayor persistencia. Se requieren protocolos de seguimiento integral, investigar mecanismos fisiopatológicos y fortalecer prevención, dado el impacto individual y socioeconómico de la enfermedad.

Introduction: Chikungunya virus (CHIKV) causes a disease with well-documented acute manifestations, but there is limited data on the persistence of symptoms and long-term sequelae. Objectives: To evaluate the persistence of signs, symptoms, and associated factors in patients with CHIKV infection during a 6-month post-infection follow-up. Material and Methods: An ambispective cohort study that included confirmed cases of CHIKV reported in April 2023 in Coronel Oviedo, Paraguay. Interviews were conducted at 1, 3 and 6 months post-infection. Demographic characteristics, comorbidities, rheumatic, and symptomatic manifestations were analyzed. Results: 333 participants were enrolled, with 170 patients completing the 6-month follow-up. At 6 months, the following symptoms persisted: back pain (61.2%), arthritis (57.1%), headache (54.1%), fatigue (51.2%), myalgia (49.4%), weakness (47.6%), depression (45.9%), and arthralgia (45.9%). The persistence of arthritis (OR 7.54, p=0.008) and myalgia (OR 3.24, p=0.031) at 6 months was higher in the 36-45 age group. Conclusions: High persistence of musculoskeletal symptoms and fatigue up to 6 months post-infection, with a decreasing trend but exacerbation of depression. Age between 36-45 years was associated with greater persistence. Comprehensive follow-up protocols, investigation of pathophysiological mechanisms, and strengthening prevention are required, given the individual and socioeconomic impact of the disease.

RESUMO

Background: Previous studies reported the negative impact of social isolation on mental health in people with dementia (PwD) and their caregivers, butlongitudinal studies seem scarcer. Objective: To describe a one-year follow-up impact of the COVID-19 pandemic on PwD and their caregivers in both Brazil and Chile. Methods: This study analyzed the impact of the pandemic on the psychological and physical health of PwD and their family caregivers after one year of follow-up in three outpatient clinics in Brazil (n = 68) and Chile (n = 61). Results: In both countries, PwD reduced their functional capacity after one year of follow-up (p = 0.017 and p = 0.009; respectively) and caregivers reported worse physical and mental health (p = 0.028 and p = 0.039). Only in Chile, caregivers reported more sadness associated with care (p = 0.001), and reduced time sleeping (p = 0.07). Conclusions: In conclusion, the COVID-19 pandemic appears to have had a long-lasting impact on PwD and their caregivers. However, it is essential to acknowledge that the inherent progression of dementia itself may also influence changes observed over a year.

RESUMO

Introducción. Las tasas de retención en los estudios de seguimiento oscilan entre el 32 y 100%, demostrando el desafío que implica realizar estudios longitudinales de sobrevivientes de la unidad de cuidados intensivos (UCI). Objetivo. Identificar las estrategias implementadas y lecciones aprendidas en un estudio prospectivo multicéntrico de seguimiento de sobrevivientes de la UCI durante la pandemia. Métodos. Estudio post-hoc de las lecciones aprendidas mediante encuestas y entrevistas dirigidas a explorar la experiencia de los investigadores y coordinadores del estudio IMPACCT COVID-19, realizado en siete centros chilenos entre octubre 2020 y abril 2021 evaluando el síndrome post-cuidados intensivos de sobrevivientes hasta seis meses después. Resultados. Identificamos ocho lecciones: 1) selección de instrumentos de medición, 2) identificación de centros participantes, 3) aprobación del estudio, 4) financiamiento, 5) capacitación de evaluadores, 6) coordinación/aseguramiento de calidad, 7) reclutamiento y 8) seguimiento de pacientes. Incluso durante el primer año de pandemia, reclutamos 252 pacientes a una tasa de 1,4 pacientes/día con una retención del 48% a los 6 meses de seguimiento. El uso de redes académicas existentes y las estrategias de comunicación entre investigadores, coordinadores y evaluadores fueron aspectos positivos; mientras que la fidelización con evaluadores al egreso de la UCI y con pacientes durante el seguimiento son aspectos que deberían considerarse en futuros estudios. Conclusiones. Se evaluaron más de 250 pacientes en seis meses durante la pandemia, con tasas de retención post UCI acorde a la literatura. Futuros estudios debiesen optimizar los procesos de medición y de seguimiento para minimizar la pérdida de pacientes.

Background. Retention rates of follow-up studies range from 32 to 100%, demonstrating the challenge to conduct longitudinal studies of intensive care unit (ICU) survivors. Objective. To identify the strategies implemented and lessons learned in a multicenter prospective follow-up study of ICU survivors during pandemic times. Methods. Post-hoc study of lessons learned through surveys and interviews aimed at exploring the experience of the researchers and coordinators of the IMPACCT COVID-19 study. The original study was performed in seven Chilean sites between October 2020 and April 2021 evaluating the post-intensive care syndrome of survivors up to six-month follow-up. Results. We identified eight lessons: 1) selection of measurement instruments, 2) identification of participating sites, 3) Study approval, 4) funding, 5) evaluators training, 6) coordination/quality assurance, 7) recruitment, and 8) patient follow-up. Even during the first year of the pandemic, we recruited 252 patients at a rate of 1.4 patients/day with a retention rate of 48% at 6 months of follow-up. The use of existing academic networks and communication strategies between researchers, coordinators and evaluators were positive aspects; while evaluators fidelity at ICU discharge and patient engagement during follow-up are aspects should be considered. Conclusions. More than 250 patients were evaluated in six months during the pandemic, with post-ICU retention rates consistent with the literature. Future studies should optimize measurement and monitoring processes to minimize patient atrition.

RESUMO

PURPOSE: To compare health-related quality of life (HRQoL) and functional status between obese, underweight, normal-weight, and overweight patients after three months post-intensive care unit (ICU) discharge. METHODS: Multicenter cohort study (10 Brazilian ICUs). 1600 ICU survivors (≥ 72 h in the ICU) were included.The main outcomes were HRQoL and functional status assessed three months after the ICU discharge. The secondary outcomes were mortality, hospital readmission, and ICU readmission during the same period. RESULTS: Obese patients (median 50.1; IQR 39.6-59.6) had lower HRQoL in the mental component than normal-weight patients (median 53; IQR 45.6-60.1) (p = 0.033). No differences were found between BMI categories regarding the physical component of HRQoL and the Barthel Index (p = 0.355 and 0.295, respectively). Regarding readmissions, 65.1 and 25.1% of patients were readmitted to the hospital and ICU, but there was no difference between the groups (p = 0.870 and 0.220, respectively). Obese patients died less frequently (11.8%) than underweight (30.9%) and normal-weight (19.3%) patients (p < 0.001). CONCLUSION: After three months of post-ICU discharge, obese patients had lower HRQoL in the mental component than normal-weight patients. However, obese patients died less than underweight and normal-weight patients.

Métodos revisão integrativa realizada em oito bases de dados, com auxílio de um gerenciador de referências bibliográficas, utilizando o modelo de JBI para a análise do nível de evidência. Os dados foram organizados, categorizados e discutidos por meio de síntese descritiva. Resultados 10 estudos compuseram a amostra final, sendo dois apenas com enfermeiros e os demais com enfermeiros e médicos. Os principais desfechos avaliados foram perfuração e expulsão, sem diferenças significativas entre os profissionais que realizaram o procedimento. As taxas de sucesso, continuidade e satisfação foram semelhantes entre médicos e enfermeiros. Conclusão os desfechos das inserções de dispositivos intrauterinos por enfermeiros em instituições de saúde são similares aos realizados por médicos, com ampliação do acesso, sem aumentar as complicações relacionadas a esse método contraceptivo, contribuindo para a integralidade da assistência no campo do planejamento reprodutivo. Contribuições para a prática: os achados podem contribuir para o enfrentamento de barreiras pelos enfermeiros, servindo como subsídio para diretrizes e políticas de saúde que incentivem a inserção do dispositivo intrauterino por estes profissionais, principalmente, em contextos onde esta prática ainda não ocorre.

ABSTRACT Objective to identify the outcomes of intrauterine device insertions by nurses in healthcare institutions. Methods integrative review carried out in eight databases, with the help of a bibliographic reference manager, using the JBI model for analyzing the evidence level. The data was organized, categorized and discussed using descriptive summaries. Results 10 studies made up the final sample, two with nurses only and the others with nurses and physicians. The main outcomes assessed were perforation and expulsion, with no significant differences between the professionals who performed the procedure. Success rates, continuity and satisfaction were similar between physicians and nurses. Conclusion the outcomes of intrauterine device insertions by nurses in health institutions are similar to those carried out by physicians, with increased access, without increasing the complications related to this contraceptive method, contributing to comprehensive care in the field of reproductive planning. Contributions to practice: the findings could help nurses to tackle barriers and serve as a basis for guidelines and health policies that encourage the insertion of the intrauterine device by these professionals, especially in contexts where this practice does not yet take place.

RESUMO

Abstract Introduction COVID-19 could leave important consequences, including functional decline. Objective Eval-uate functional status in pediatric patients hospitalized with COVID-19 and correlate with clinical variables. Methods Prospective and retrospective longitudinal study with patients with COVID-19. Hospitalization data were collected from medical record review and post discharge data were collected by telephone contact. Functional status was evaluated by Functional Status Scale (FSS-Brazil) in three moments (hospital admission, hospi-tal discharge and after hospital discharge). Spearman test was used to correlate continuous variables and the linear model with generalized estimation equations was used to verify differences in the proportion of functional impairment occurrence (FSS-Brazil ≥ 8) at different mo-ments of the study and previous disease presence. Results It was included 232 patients, 56% male, median age of five years old. Seventy (30.2%) patients had post discharge data. The mean global score of FSS-Brazil was 7.3 at hospital admission, 6.8 at discharge hospital and 6.8 after discharge hospital. Functional status was adequate in the three different moments evaluated in 75% of the sample. The ventilatory support needed was not correlated with functional status and the length of hos-pital stay and oxygen therapy showed weak correlations with functional status. Having no previous disease reduced the risk of functional impairment by 94%. Conclusion The majority of the patients maintained adequate functional status. Absence of previous disease was a protective factor for long term functional impairment.

Resumo Introdução A COVID-19 pode deixar sequelas impor-tantes, como declínio funcional. Objetivo Avaliar a funcionalidade dos pacientes pediátricos internados com COVID-19 e correlacionar com variáveis clínicas. Métodos Estudo longitudinal retrospectivo e prospectivo, com pacientes pediátricos com COVID-19. Os dados de internação hospitalar foram coletados a partir da revisão de prontuários e os dados pós-alta através de contato telefônico. A funcionalidade foi avaliada através da Escala de Estado Funcional Pediátrica (FSS-Brasil) em três momentos (admissão, alta e pós-alta hospitalar). A correlação entre as variáveis contínuas foi avaliada pelo teste de Spearman e utilizou-se o modelo linear com equações de estimação generalizada para verificar as diferenças nas proporções de ocorrência de prejuízo funcional (FSS-Brasil ≥ 8) nos diferentes momentos do estudo e na presença de doenças prévias. Resultados Foram incluídos 232 pacientes, 56% do sexo masculino, mediana de 5 anos de idade. Foram obtidos dados de seguimento pós-alta hospitalar de 70 (30,2%) crianças. O escore global médio da FSS-Brasil foi de 7,3 na admissão, 6,8 na alta e 6,8 após a alta. A funcionalidade apresentou-se adequada nos três momentos de avalia-ção em 75% da amostra. A necessidade de suporte ven-tilatório não foi correlacionado com a funcionalidade, e o tempo de internação e oxigenoterapia apresentaram correlações fracas com a funcionalidade. A inexistência de doenças prévias reduziu em 94% o risco de prejuízo funcional. Conclusão A maioria das crianças manteve funcionalidade adequada. Não ter doenças prévias foi um fator de proteção para o prejuízo funcional em longo prazo.

RESUMO

ABSTRACT Introduction: The impact of mitral regurgitation (MR) on valve-in-valve transcatheter aortic valve implantation (VIV-TAVI) in patients with failed bioprostheses remains unclear. The purpose of this study was to assess the prognostic impact of residual moderate MR following VIV-TAVI. Methods: We retrospectively analyzed 127 patients who underwent VIV-TAVI between March 2010 and November 2021. At least moderate MR was observed in 51.2% of patients before the procedure, and MR improved in 42.1% of all patients. Patients with postoperative severe MR, previous mitral valve intervention, and patients who died before postoperative echocardiography were excluded from further analyses. The remaining 114 subjects were divided into two groups according to the degree of postprocedural MR: none-mild MR (73.7%) or moderate MR (26.3%). Propensity score matching yielded 23 pairs for final comparison. Results: No significant differences were found between groups before and after matching in early results. In the matched cohort, survival probabilities at one, three, and five years were 95.7% vs. 87.0%, 85.0% vs. 64.5%, and 85.0% vs. 29.0% in the none-mild MR group vs. moderate MR-group, respectively (log-rank P=0.035). Among survivors, patients with moderate MR had worse functional status according to New York Heart Association (NYHA) class at follow-up (P=0.006). Conclusion: MR is common in patients with failed aortic bioprostheses, and improvement in MR-status was observed in over 40% of patients following VIV-TAVI. Residual moderate MR after VIV-TAVI is not associated with worse early outcomes, however, it was associated with increased mortality at five years of follow-up and worse NYHA class among survivors.

RESUMO

Purpose: To estimate the prevalence and severity of impairments in functional status, fatigue, and health-related quality of life (HRQoL) among critical COVID-19 survivors one-year after hospital discharge. Methods: A systematic review was conducted following PRISMA statement and registered in PROSPERO (CRD42021258356), with searches in eight databases. Observational studies were selected. The prevalence meta-analysis of abnormalities was performed using random-effects models. Risk of bias was evaluated using the National Heart, Lung, and Blood Institute tool. Results: Twenty studies were included, with data collected between 12 and 13.5 months after hospital discharge and a total of 1828 participants. Of these, 71% were men, and 77.7% were intubated in the intensive care unit (ICU). Impairments and sequelae were identified in varying prevalence and degrees, with greater impact on functional capacity and physical components of fatigue and HRQoL. The prevalence of abnormalities of 32.3% [95% CI 23.9; 41.9] found in the meta-analysis is substantially high. Most studies were classified as having fair and poor quality. Conclusion: Critical COVID-19 survivors experience impairments in functional status, fatigue, and HRQoL to varying degrees one-year after hospital discharge, particularly among patients who stayed in the ICU and on MV for a prolonged period.

Critical COVID-19 survivors exhibit persistent impairments one-year post-discharge.Functional status, fatigue, and health-related quality of life are impaired to varying degrees in approximately one-third of patients.Long-term follow-up care for critical COVID-19 survivors should be prioritized.

RESUMO

PURPOSE: Peri-implant mucositis (PIM) and peri-implantitis (PI) are multicausal conditions with several risk factors contributing to their pathogenesis. In this study, we retrospectively investigated risk variables potentially associated with these peri-implant diseases (PIDs) over a follow-up period of 1 to 18 years. METHODS: The study sample consisted of 379 implants placed in 155 patients. Single-visit clinical and radiographic evaluations were employed to determine the presence or absence of PIDs. Parameters related to the patient, site, surgery, implant, and prosthetic restoration were documented. The relationships between risk variables and the occurrence of PIDs were individually examined and adjusted for confounders using multivariate binary logistic regression models. RESULTS: The prevalence rates of PIM and PI were 28.4% and 36.8% at the patient level and 33.5% and 24.5% at the implant level, respectively. Poor oral hygiene, active gingivitis/periodontitis, preoperative alveolar ridge deficiency, early or delayed implant placement, implant length of 11.0 mm or less, and poor restoration quality were strong and independent risk indicators for both PIDs. Furthermore, a follow-up period of more than 5 years and a loading time of more than 4 years were important indicators for PI. Simultaneously, age and smoking status acted as modifiers of the effect of mesiodistal (MD) and buccolingual (BL) widths of restoration on PI. CONCLUSIONS: In this study population, oral hygiene, periodontal status, preoperative alveolar ridge status, implant placement protocol, implant length, and the quality of coronal restoration appear to be robust risk indicators for both PIM and PI. Additionally, the length of follow-up and functional loading time are robust indicators of PI. Furthermore, the potential modifying relationships of age and smoking status with the MD and BL widths of restoration may be crucial for the development of PI.

RESUMO

Objective: The ceramic-on-metal (CoM) bearing has the theoretical advantages over ceramic-on-ceramic (CoC) and metal-on-metal bearings. This study aimed to analyze factors affecting the metal ion release of CoM bearings and compare clinical performance with CoC bearings. Methods: The 147 patients were divided into 96 patients in group 1 (CoM group) and 51 patients in group 2 (CoC group). Additionally, within group1, 48 patients and 30 patients were sub-categorized into group 1-A with leg length discrepancy (LLD) less than 1cm and group 1-B greater than 1 cm. The level of serum metal ions, functional scores and plain radiographs were obtained for the analysis. Results: The level of cobalt (Co) 2-years after surgery and chromium (Cr) 1-year after surgery showed significantly higher in the group1 than the group2. LLD indicated statistically significant positive correlation between serum metal ion levels among CoM bearing THAs. In comparison of the average metal ions level changes, group 1-B showed higher level of metal ion than group 1-A. Conclusion: In patients underwent THA with CoM bearings, large LLD have a higher risk of complications associated to metal ions. Therefore, it is critical to reduce the LLD to 1 cm or less in using CoM bearing. Level of Evidence III; Case Control Study.

Objetivo: Uma superfície metalocerâmica (CoM) apresenta vantagens teóricas sobre as superfícies cerâmica-cerâmica (CoC) e metal-metal. Este estudo teve como objetivo analisar os fatores que afetam a liberação de íons metálicos das superfícies CoM e comparar o desempenho clínico com as superfícies CoC. Métodos: Os 147 pacientes foram divididos em 96 pacientes no grupo 1 (grupo CoM) e 51 pacientes no grupo 2 (grupo CoC). No grupo 1, 48 pacientes foram subcategorizados em grupo 1-A, com discrepância de comprimento das pernas (LLD) menor que 1 cm; e 30 pacientes no grupo1-B maior que 1 cm. O nível de íons metálicos séricos, escores funcionais e radiografias foram obtidas para a análise. Resultados: Os níveis de cobalto (Co) 2 anos após a cirurgia e de cromo (Cr), após o primeiro ano da cirurgia mostraram-se significativamente mais altos no grupo 1 do que no grupo 2. A LLD indicou correlação positiva estatisticamente significativa entre os níveis de íons do soro metálico entre os portadores de THA de CoM. Em comparação com as alterações médias dos níveis de íons metálicos, o grupo 1-B revelou um nível de íons metálicos mais alto do que o grupo 1-A. Conclusão: Em pacientes submetidos a THA com superfícies CoM e elevada LLD têm um maior risco de complicações associadas a íons metálicos. Sendo fundamental reduzir LLD para 1 cm ou menos no uso de superfícies CoM. Nível de Evidência III; Estudo de Controle de Caso.

RESUMO

INTRODUCTION: Immediate completion lymph node dissection (CLND) performed in patients with a positive sentinel lymph node biopsy (SLNB) cutaneous melanoma is not associated with improved melanoma specific survival versus active surveillance (AS) using nodal ultrasound. Clinical practice experience and outcomes of AS and adjuvant therapy is now starting to be published in literature. METHODS: Retrospective analysis of patients with a positive-SLNB between June/2017-February/2022. Impact of management on any-site recurrence free survival (RFS), isolated nodal recurrence (INR), distant metastasis-free survival (DMFS) and melanoma-specific survival (MSS) was evaluated. RESULTS: From 126 SLNB, 31 (24.6%) were positive: 24 received AS and 7 CLND. Twenty-one (68%) received adjuvant therapy (AS, 67% and CLND, 71%). With a median follow-up of 18 months, 10 patients developed recurrent disease with an estimated 2-yr RFS of 73% (CI95%, 0.55-0.86) (30% in AS group vs. 43% in dissection group; P = 0.65). Four died of melanoma with an estimated 2-yr MSS of 82% (CI 95%, 0.63-0.92) and no differences between AS and CLND groups (P = 0.21). Estimated 2-yr DMFS of the whole cohort was 76% (CI 95%, 0.57-0.88) with no differences between groups (P = 0.33). CONCLUSION: Active surveillance strategy has been adopted for most positive-SLNB cutaneous melanoma patients. Adjuvant therapy without immediate CLND was delivered in nearly 70% of patients. Our results align with outcomes of randomized control trials and previous real-world data.

Introducción: La linfadenectomía inmediata (LI) realizada en pacientes con biopsia de ganglio centinela (BGC) positivo por melanoma cutáneo no está asociada a mejoría en la supervivencia libre de enfermedad vs. vigilancia activa (VA). Resultados oncológicos y experiencia en la práctica clínica con dicha conducta asociados a tratamiento adyuvante comienzan a ser publicados en la literatura. Métodos: Análisis retrospectivo incluyendo pacientes con BGC-positiva por melanoma cutáneo entre junio/2017-febrero/2022. Se evaluó impacto del manejo en: supervivencia libre de recurrencia (SLR), recurrencia ganglionar aislada (RGA), supervivencia libre de metástasis a distancia (SLMD) y supervivencia libre de enfermedad (SLE). Resultados: De 126 pacientes, 31 (24.6%) fueron positivos: en 24 se realizó VA y en 7 LI. Veintiún pacientes (68%) recibieron tratamiento adyuvante (VA, 67% y LI, 71%). Con una media de seguimiento de 18 meses, 10 pacientes presentaron recurrencia de la enfermedad con una SLR estimada a 2 años del 73% (CI95%, 0.55-0.86) (30% en VA vs. 43% en LI; P = 0.65). Cuatro murieron de melanoma con una SLE a 2 años del 82% (CI 95%, 0.63-0.92); sin diferencia entre ambos grupos (P = 0.21). La SLMD a 2 años de toda la cohorte fue de 76% (CI 95%, 0.57-0.88; P = 0.33). Conclusión: La vigilancia activa se ha adoptado como conducta para la mayoría de los pacientes con BGCpositivo. El tratamiento adyuvante sin linfadenectomía inmediata se realizó en cerca del 70% de nuestra serie. Los resultados de nuestra serie son similares a los reportados en la literatura.

RESUMO

Background Craniofacial fibrous dysplasia (CFD) is an uncommon benign condition in which a bone is replaced by fibrous tissue. An adequate clinical characterization considering the number of affected bones and functional impairment is important to determine the most effective surgical intervention for its management. This study aims to present our institution's experience in the evaluation and management of CFD. Methods This was a retrospective study that included patients with CFD managed at our institution. Data included demographic characteristics, afflicted bones, surgical procedures performed, and recurrence. Results are presented as mean and percentages. Recurrence-free years and association between the type of surgery and recurrence was evaluated. Results Eighteen patients were included (11 females, 61%). The zygomatic, maxillary, and frontal bones were the most commonly affected with eight (18%) cases each. The most common procedure was bone burring, with 36 procedures. Recurrence was more prevalent after burring (58.3%) and occurred earlier than in the bone resection group (13 vs. 15 years, p > 0.05). Conclusion Surgery continues to be the cornerstone of CFD treatment. Bone burring is effective for debulking and contouring but increases the risk for recurrence. An individualized approach should be tailored according to the anatomical location of the disease, type of CFD, behavior of the lesion, and accompanying clinical complaints.

RESUMO

Introduction: The aim of our work is to review those patients who underwent prosthetic hip revision surgery in our hospital considered to be patients at high risk of dislocation or recurrent dislocation, and who underwent a double mobility cemented cup (CMD). Analyzing the different ways to place these cups and the clinical results and reluxations. Material and methods: The 69 cases comprised 34 men and 35 women with a mean age of 77,39 years. The mean follow-up was 4.7536 years. The type of intervention performed varied according to the cause of the intervention, the acetabular bone stock and the state of the primary cup. In the cases in which there was a good fixation of the primary metalback, we opted to carry out a cementation of the cemented DMC into the existing well-fixed metal acetabular shell, this occurred in 23 cases. In the cases where there was loosening of the primary cup but there was a good bone stock, a CMD was cemented into the bone (21 cases). In the cases where there was a Paprosky type III we cemented a DMC to a Bursch-Schneider reinforcement ring together with the placement of a cancellous bone graft (25 cases). Results: The clinical evaluation at the end of the follow-up, according to the MD Scale, showed the mean value was 16.454 (SD 0.79472), with a survival at the end of the follow-up of 100% of the placed DMC. Conclusion: The use of cemented DMC is a good solution in the replacement of THA, especially in cases of reluxation or risk of dislocation due to personal or technical predisposing factors. The use of these DMC cemented can be directly to the bone, into the existing well-fixed metal Shell, or cemented to a reinforcing ring, depending on the acetabular defect.

Introdução: Revisar os pacientes que foram submetidos à cirurgia de revisão protética de quadril neste hospital, considerados como pacientes com alto risco de luxação ou luxação recorrente, submetidos a cirurgia por acetábulo cimentado de dupla mobilidade (CMD). Analisando as diferentes formas de posicionamento desses copos, seus resultados clínicos e reluxações. Material e métodos: Os 69 casos correspondiam a 34 homens e 35 mulheres com uma idade média de 77,39 anos. O tempo médio de acompanhamento foi de 4,7536 anos. O tipo de intervenção realizada variou de acordo com a causa da intervenção, o estoque ósseo acetabular e o estado do copo primário. Nos casos em que houve uma boa fixação do metal primário, optouse por realizar uma cimentação do DMC cimentado na cúpula acetabular metálica firme existente, o que ocorreu em 23 casos. Nos casos em que houve um afrouxamento acetabular primário com um bom estoque ósseo disponível, cimentou-se um CMD (21 caixas). Nos casos em que havia um Paprosky tipo III, cimentou-se um DMC a um anel de reforço Bursch-Schneider juntamente com a colocação de um enxerto ósseo esponjoso (25 caixas). Resultados: A avaliação clínica realizada no final do acompanhamento, de acordo com a Escala MD, mostrou que o valor médio foi de 16,454 (DP 0,79472), com uma sobrevivência ao final do acompanhamento de 100% do DMC inserido. Conclusão: O uso do DMC cimentado pode ser uma boa solução para substituição do THA, especialmente em casos de reluxação ou risco de deslo-camento devido a fatores de predisposição pessoais ou técnicos. O uso destes DMC cimentados pode ser realizado diretamente ao osso, dentro da cúpula metálica fixa existente, ou cimentados a um anel de reforço, dependendo do defeito acetabular.

RESUMO

Introducción: Las fracturas intertrocantéricas del extremo proximal del fémur constituyen el grupo nosológico con mayor morbilidad y mortalidad de las lesiones traumáticas del esqueleto. Objetivo: Evaluar la reducción, la colocación del implante y el tiempo de consolidación. Métodos: Se realizó un estudio descriptivo, longitudinal y prospectivo de 114 pacientes con diagnóstico de fracturas del extremo proximal del fémur tratadas con clavo femoral proximal, y un seguimiento posoperatorio de un año. Resultados: Se alcanzó un resultado clínico funcional de excelente a bueno en el 82,4 % de los casos. Se evidenciaron signos radiológicos de consolidación en un promedio de 4,2 meses en la mayor parte de la muestra. Conclusiones: La pérdida de la fijación constituyó la complicación más frecuente; por tanto, se considera que el enclavado femoral proximal ofrece buenos resultados en el tratamiento de fracturas intertrocantéricas inestables del fémur.

Introduction: Intertrochanteric fractures of the proximal end of the femur constitute the nosological group with the highest morbidity and mortality of traumatic skeletal injuries. Objective: To evaluate reduction, implant placement and consolidation time. Methods: A descriptive, longitudinal and prospective study was carried out in 114 patients with diagnosis of fractures of the proximal end of the femur treated with proximal femoral nailing, and a one-year postoperative follow-up. Results: A functional clinical result from excellent to good was achieved in 82.4% of the cases. Radiological signs of consolidation were evidenced in an average of 4.2 months in most of the sample. Conclusions: Loss of fixation was the most frequent complication; therefore, proximal femoral nailing is considered to offer good results in the treatment of unstable intertrochanteric fractures of the femur.

RESUMO

ABSTRACT Introduction: Acute type A aortic dissection (AAAD) in late pregnancy is a rare but severe disease. Lack of clinical experience is the main cause of high mortality. This study tries to investigate the multidisciplinary therapeutic strategy for these patients. Case presentation: We reported three patients with AAAD in late pregnancy. Sudden chest pain was the main clinical symptom before operation. All three patients and their newborns survived through multidisciplinary approach in diagnosis and treatment. No serious complications occurred during the mid-term follow-up. Conclusion: Multidisciplinary diagnosis and treatment strategy play a crucial role in saving the lives of pregnant women with AAAD.
