Manejo cirúrgico de ferimento auto-infligido por arma de fogo em região maxilofacial / Surgical management of self-inflicted injury by gun in the maxillofacial region

INTRODUÇÃO: O manejo dos pacientes vítimas de PAF possui vertentes divergentes a respeito do tratamento cirúrgico, que pode ser realizado de forma imedata ou tardia. Em lesões auto-infligidas, a distância entre a arma e a região acometida é menor, causando consequências estéticas e funcionais mais devastadoras. Aliado ao fato desse tipo de trauma criar uma ferida suja devido à comunicação com a cavidade oral e seios paranasais, o manejo das lesões representam um desafio mesmo à cirurgiões experientes. OBJETIVO: Estre trabalho relata o manejo cirúrgico de uma ferida auto-infligida por arma de fogo que resultou em avulsão dos tecidos moles na região maxilofacial. DESCRIÇÃO DO CASO: Paciente do sexo masculino, 35 anos, vítima de projétil de arma de fogo auto-infligido em região maxilofacial, cursando com extenso ferimento em região de língua e mento. Clinicamente, o paciente não apresentava sinais de fratura em ossos da face. Ambos os ferimentos apresentavam secreção purulenta e o paciente manifestava disfonia devido a grande destruição tecidual. CONSIDERAÇÕES FINAIS: O tratamento de ferimentos por arma de fogo não só é um grande desafio para o cirurgião, como para toda a equipe multidisciplinar requerida para tais casos, visto que não há protocolos bem definidos para o tratamento dessas lesões(AU)

INTRODUCTION: The management of patients who are victims of FAP has divergent aspects regarding surgical treatment, which can be performed immediately or late. In self-inflicted injuries, the distance between the weapon and the affected region is smaller, causing more devastating aesthetic and functional consequences. Allied to the fact that this type of trauma creates a dirty wound due to the communication with the oral cavity and paranasal sinuses, the management of injuries represents a challenge even for experienced surgeons. OBJECTIVE: This paper reports the surgical management of a self-inflicted gunshot wound that resulted in soft tissue avulsion in the maxillofacial region. CASE DESCRIPTION: Male patient, 35 years old, victim of a self-inflicted firearm projectile in the maxillofacial region, coursing with extensive injury in the region of the tongue and chin. Clinically, the patient did not show signs of facial bone fractures. Both wounds had purulent secretion and the patient had dysphonia due to extensive tissue destruction. FINAL CONSIDERATIONS: The treatment of gunshot wounds is not only a great challenge for the surgeon, but also for the entire multidisciplinary team required for such cases, since there are no well-defined protocols for the treatment of these injuries(AU)

Small Molecules Accelerate Skin Wound Healing: Shikonin Efficacy and Mechanism of Action in Mice / Las Moléculas Pequeñas Aceleran la Curación de Heridas en la Piel: Eficacia de Shikonin y Mecanismo de Acción en Ratones

SUMMARY: The objective of this study was to investigate the therapeutic wound healing potential and molecular mechanisms of shikonin as small molecules in vitro. A mouse burn model was used to explore the potential therapeutic effect of shikonin; we traced proliferating cells in vivo to locate the active area of skin cell proliferation. Through the results of conventional pathological staining, we found that shikonin has a good effect on the treatment of burned skin and promoted the normal distribution of skin keratin at the damaged site. At the same time, shikonin also promoted the proliferation of skin cells at the damaged site; importantly, we found a significant increase in the number of fibroblasts at the damaged site treated with shikonin. Most importantly, shikonin promotes fibroblasts to repair skin wounds by regulating the PI3K/AKT signaling pathway. This study shows that shikonin can effectively promote the proliferation of skin cell, and local injection of fibroblasts in burned skin can play a certain therapeutic role.

El objetivo de este trabajo fue investigar el potencial terapéutico de cicatrización de heridas y los mecanismos moleculares de la shikonina como moléculas pequeñas in vitro. Se utilizó un modelo de quemaduras en ratones para explorar el posible efecto terapéutico de la shikonina; Rastreamos las células en proliferación in vivo para localizar el área activa de proliferación de células de la piel. A través de los resultados de la tinción para patología convencional, encontramos que la shikonina tiene un buen efecto en el tratamiento de la piel quemada y promueve la distribución normal de la queratina de la piel en el sitio dañado. Al mismo tiempo, la shikonina también promovió la proliferación de células de la piel en el sitio dañado. Es importante destacar que encontramos un aumento significativo en la cantidad de fibroblastos en el sitio dañado tratado con shikonina. Lo más importante es que la shikonina promueve la función reparadora de fibroblastos en las heridas de la piel regulando la vía de señalización PI3K/ AKT. Este estudio muestra que la shikonina puede promover eficazmente la proliferación de células de la piel y que la inyección local de fibroblastos en la piel quemada puede desempeñar un cierto papel terapéutico.

Chinese Medicine Intervention in Signaling Pathways Related to Diabetic Ulcer： A Review / 中国实验方剂学杂志

Diabetic ulcer （DU） wound is one of the chronic and serious complications of diabetes characterized by prolonged wound healing， and it is more common in foot and lower extremity ulcers. DU has brought great economic and psychological pressure to patients and seriously affected the quality of life of patients because of its great difficulty in treatment， long treatment process， and high morbidity and mortality. Therefore， how to help the rapid healing of DU wounds， reduce the disability rate and mortality rate， protect limb function， and improve the quality of life is an important topic and hot spot in the field of medical research. The pathogenesis of DU is complex， mainly including microcirculation disorder， peripheral neuropathy， inflammation and infection， and excessive apoptosis of cells， involving physiological processes such as wound inflammation， granulation tissue hyperplasia and re-epithelialization. A large number of previous studies have found that Chinese medicine can regulate phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， Wnt/β-catenin， nuclear factor-κB （NF-κB）， Notch， nuclear factor E2-related factor 2 （Nrf2）， transforming growth factor-β （TGF-β）/Smad， and other signaling pathways， regulate abnormal glucose metabolism， improve microcirculation， inhibit inflammation and oxidative stress， regulate cell proliferation and excessive apoptosis， and promote wound tissue growth to promote the rapid healing of DU wounds under the guidance of treatment based on traditional Chinese medicine （TCM） syndrome differentiation and internal and external treatment. Therefore， this paper reviewed Chinese medicinal monomers or Chinese medicinal compounds in recent years in regulating the above signaling pathways and the expression of key protein molecules and promoting the rapid healing of DU wounds， aiming to provide ideas and a theoretical basis for the in-depth study and clinical application of Chinese medicine in promoting the healing of DU wounds.

Effect and mechanism of Panax notoginseng saponins on wound healing after anal fistula surgery in rats / 中国药房

OBJECTIVE To investigate the effect and mechanism of Panax notoginseng saponins （PNS） on wound healing after anal fistula surgery in rats by regulating the hypoxia-inducible factor-1α （HIF-1α）/vascular endothelial growth factor （VEGF）/ vascular endothelial growth factor receptor-2 （VEGFR2） signaling pathway. METHODS SD rats were selected to establish a postoperative rat model of anal fistula by infecting wound with Escherichia coli. The model rats were randomly grouped into model group， PNS low-dose and high-dose groups （15， 30 mg/cm2）， high-dose of PNS+2-methoxyestradiol （2ME2） group （PNS 30 mg/cm2+HIF-1α inhibitor 2ME2 4 mg/kg）， with 10 rats in each group. Another 10 normal rats were selected for back hair removal treatment as the control group. Each drug group was injected with the corresponding drug solution intramuscularly or （and） intraperitoneally， once a day， for 3 weeks. After the last administration， the wound healing rate （excluding the control group）， microvascular density （MVD）， the expression of collagen Ⅰ and fibronectin （FN） in the wound tissue were detected in each group； the levels of angiogenic factors [VEGF， E-mail：842710813@qq.com angiopoietin-Ⅰ （Ang-Ⅰ）， Ang-Ⅱ] in serum， the levels of inflammatory factors [interleukin-6 （IL-6） and IL-2] in serum binggui7183@163.com and wound tissue as well as the expressions of the related proteins of HIF-1α/VEGF/VEGFR2 signaling pathway in the wound tissue of rats were also detected in each group. RESULTS The MVD， the expression of collagen Ⅰ and FN in the wound tissue， and the levels of IL-6 and IL-2 in serum and wound tissue of rats increased significantly in the model group， compared to the control group （P＜0.05）， while the serum levels of VEGF， Ang- Ⅰ and Ang-Ⅱ decreased significantly （P＜0.05）. The wound healing rate， the MVD in wound tissue， the serum levels of VEGF， Ang-Ⅰ and Ang-Ⅱ， the expressions of collagen Ⅰ and FN in the wound tissue， and protein expressions of HIF-1α， VEGF and VEGFR2 in the PNS low-dose and high-dose groups increased significantly， compared to the model group （P＜0.05）， while the levels of IL-6 and IL-2 in serum and wound tissue decreased significantly （P＜0.05）； the high-dose PNS had a stronger effect （P＜ 0.05）. 2ME2 could weaken the effect of PNS on above indicators of rats after anal fistula surgery （P＜0.05）. CONCLUSIONS PNS can promote the production of angiogenic factors and inhibit the production of pro-inflammatory factors， thereby promoting wound healing in rats after anal fistula surgery. The above effects are related to the activation of HIF-1α/VEGF/VEGFR2 signaling pathway.

Modulation Agents of Wound Healing in Ocular Surgeries

@#Wound healing is a complex process that includes haemostasis and inflammation, followed by a proliferation period and repair and finally remodelling. Ocular surgeries, particularly in glaucoma cases, aim at minimal fibrosis to preserve the function of trabeculectomy as an alternative pathway for aqueous drainage. Hence, it is important to find an agent to modulate the wound healing process. This review presents compilation of wound modulation agents that have been tested in vitro, in vivo, or clinically on patients undergoing ocular surgeries, particularly for glaucoma. We identified agents into four groups, mostly for glaucoma filtration operations: anti-metabolites, anti-growth factors, mechanical barriers and rho kinases. The effect of these agents is highlighted in this review. In conclusion, despite recognized drawbacks of antimetabolites, they are still regarded as the gold standard and the most efficient treatment as anti-scarring agents use in ocular surgeries. More studies are needed to inquire agents that efficient yet has minimal adverse effects both in short and long term.

Mechanism of Promoting Chronic Refractory Wound Repair by Polysaccharides in Traditional Chinese Medicine： A Review / 中国实验方剂学杂志

A chronic refractory wound is caused by continuous skin damage. At the same time， it may be formed due to repeated infection， vascular insufficiency， diabetes， tumors， chronic osteomyelitis， and other reasons， resulting in wound repair interruption and recovery delay. Chronic refractory wound seriously affects the quality of life of patients and consumes a lot of medical resources. Polysaccharides in traditional Chinese medicine （TCM） are the effective components of most TCM. Modern pharmacological studies have found that polysaccharides contained in TCM have anti-inflammatory， antioxidant， anti-radiation， hypoglycemic， antiviral， anti-tumor， hypolipidemic， and immunomodulatory effects. Through the summary and analysis of the literature， it was found that the mechanism of polysaccharides in TCM to promote chonic refractory wound repair was mainly realized from the following aspects： firstly， regulating inflammatory cytokines like interleukin-4 （IL-4）， interleukin-10 （IL-10）， interleukin-8 （IL-8）， and tumor necrosis factor-α （TNF-α） or regulating macrophage-related inflammatory proteins and chemotactic proteins like MIP-2， MCP-1， to shorten the inflammatory period. Secondly， activating growth factors like platelet-derived growth fator （PDGF）， basic fibroblast growth factor （bFGF）， TGF-α， and vascular endothelial growth factor （VEGF） to recruit endothelial cells and fibroblasts into tissue proliferation. Thirdly， activationg VEGF and its downstream receptor vascular endothelial growth factor receptor-1 （VEGFR-1） and vascular endothelial growth factor receptor-2 （VEGFR-2）-mediatated protein kinase C/extracellular regulated kinases （PKC/ERK） signaling pathway or promoting angiogenesie and improving wound blood flow through angiotensin （ANG）. Fourthly， promoting the ablility of collagen synthesis by enhancing the secretion of hydroxyproline and hyaluronic acid （HA） from fibroblasts （FB） and regulating relevant matrix metalloenzymes and their enzyme inhibitor to regulate the extracellular matrix. Fifthly， eliminating free radiccals to reduce the damage caused by oxidative stress to tissue. Sixthly， enhancing the phagocytic ability of macrophages， the activity of natural killer cells， and the proliferation of T cells to improve the defense ability of tissue. Polysaccharides in TCM can repair wounds in many ways at the same time. Its advantage lies in the multiple targets and multiple pathways. It is expected that the research will pay more attention to the mechanism of wound repair by polysaccharide components in TCM when improving the treatment of chronic refractory wounds.

Injectable platelet rich fibrin effect on laser depigmented gingiva: a clinical randomized controlled split mouth trial with histological assessment

Abstract Objective To determine whether intra-mucosal injection of injectable platelet-rich fibrin (i-PRF) can promote healing after Diode Laser Gingival Depigmentation (DLGD). Methodology A total of 20 arch sites of hyperpigmented gingiva of 10 patients underwent DLGD. For each patient, two arch sites were randomly assigned for either intra-mucosal injection of i-PRF (G1-i-PRF) (n=10 sites) or no treatment (G2-Control): (n=10 sites). Wound Healing Score (WHS), patient satisfaction, and Pigmentation Index (DOPI) were measured at 1 week and 1 and 3 months postoperatively. Histological assessment of tissue specimens was performed at baseline and 1 week. Results The percentage change in WHS at 1 week was significantly higher in G1 (58.34±15.43) compared to G2 (37.50±11.79). At day 1, 50% of patients in G1 were pain free compared with 75% in G2, who had mild pain. Mean DOPI decreased significantly at 3 months in both groups (P-value <0.001), without significant differences between groups. G1 specimens showed significantly higher epithelial thickness (P-value <0.001), as well as a higher number of blood vessels and less percentage of inflammatory cells. Conclusions i-PRF demonstrated better clinical and histological healing potential and less patient discomfort compared to sites without treatment after DLGD.

Intracorneal implantation of a misdirected foldable intraocular lens during phacoemulsification surgery: a case report / Implantação intracorneana de uma lente intraocular dobrável direcionada incorretamente durante cirurgia de facoemulsificação: relato de caso

ABSTRACT A 59-year-old man presented with a unilateral blurring of vision in his left eye. His left eye's visual acuity was hand movements level. He underwent phacoemulsification surgery, and an intrastromal posterior chamber intraocular lens was implanted. The intrastromal intraocular lens was extracted and a new intraocular lens was implanted. Usinge the Snellen chart, the final best-corrected visual acuity was 20/40. With this case report, we wish to emphasize that a single stepwise clear corneal incision merged with wound-assisted intraocular lens injections can result in intraocular lens misdirection into the corneal stroma. As a result, while performing a misdirected intraocular lens removal, we recommend that the wound be carefully constructed.

RESUMO Um homem de 59 anos apresentou embaçamento visual unilateral no olho esquerdo. Sua acuidade visual nesse olho era no nível de movimentos da mão. O paciente havia se submetido a uma cirurgia de facoemulsificação em que foi feita a implantação intraestromal de uma lente intraocular de câmara posterior. Foi feita a extração dessa lente intraestromal intraocular e uma nova lente intraocular foi implantada. A melhor acuidade visual corrigida final foi de 20/40 pela tabela de Snellen. Com este relato de caso, os autores desejam apontar que uma incisão de degrau único em córnea clara, quando combinada com a injeção de uma lente ocular através da incisão, pode levar a um direcionamento incorreto da lente intraocular para dentro do estroma corneano. Portanto, recomenda-se uma construção cuidadosa da incisão ao se remover uma lente intraocular direcionada incorretamente.

Microbiological profile and antibiotic sensitivity of maxillofacial infections in an emergency hospital

Aim: To investigate the bacteriological profile of oral and maxillofacial infections and the pattern of sensitivity to a specific group of antibiotics in a reference emergency hospital in Brazil. Methods: This is a prospective cohort institutional study that studied patients affected by oral and/ or maxillofacial infections in a Brazilian emergency hospital, over a 12-month period, of different etiologies, through data collection, culture and antibiogram tests, and monitoring of the process of resolution of the infectious condition. The variables were analyzed using the chi-square and Mann-Whitney tests, using a significance level of 5%. Results: The sample consisted of 61 patients, 62.3% male. The mean age of participants was 34.3 years. Odontogenic infection was the most frequent etiology and the submandibular space was the most affected. The bacterial species Streptococcus viridans was isolated in 21.6% of cases. Levofloxacin, vancomycin and penicillin were the antibiotics with the highest frequency of bacterial sensitivity, while clindamycin and erythromycin showed the highest percentages of resistance. Conclusions: The results suggest that, among the most used antibiotics for the treatment of these infections, penicillin remains an excellent option of choice for empirical therapy

OBJECTIVE@#To explore the feasibility and effectiveness of a foldable pedicled latissimus dorsi myocutaneous flap to repair soft tissue defects in the shoulder and back.@*METHODS@#Between August 2018 and January 2023, the foldable pedicled latissimus dorsi myocutaneous flaps were used to repair soft tissue defects in the shoulder and back of 8 patients. There were 5 males and 3 females with the age ranged from 21 to 56 years (mean, 35.4 years). Wounds were located in the shoulder in 2 cases and in the shoulder and back in 6 cases. The causes of injury were chronic infection of skin and bone exposure in 2 cases, secondary wound after extensive resection of skin and soft tissue tumor in 4 cases, and wound formation caused by traffic accident in 2 cases. Skin defect areas ranged from 14 cm×13 cm to 20 cm×16 cm. The disease duration ranged from 12 days to 1 year (median, 6.6 months). A pedicled latissimus dorsi myocutaneous flap was designed and harvested. The flap was divided into A/B flap and then were folded to repair the wound, with the donor area of the flap being pulled and sutured in one stage.@*RESULTS@#All 7 flaps survived, with primary wound healing. One patient suffered from distal flap necrosis and delayed healing was achieved after dressing change. The incisions of all donor sites healed by first intention. All patients were followed up 6 months to 4 years (mean, 24.7 months). The skin flap has a good appearance with no swelling in the pedicle. At last follow-up, 6 patients had no significant difference in bilateral shoulder joint motion, and 2 patients had a slight decrease in abduction range of motion compared with the healthy side. The patients' daily life were not affected, and linear scar was left in the donor site.@*CONCLUSION@#The foldable pedicled latissimus dorsi myocutaneous flap is an ideal method to repair the soft tissue defect of shoulder and back with simple operation, less damage to the donor site, and quick recovery after operation.

Fatores de Risco para Infecção da Ferida Operatória em Pacientes Submetidos à Cirurgia Cardíaca Pediátrica / Risk Factors for Surgical Site Infection in Patients Undergoing Pediatric Cardiac Surgery

Resumo Fundamento A infecção do sítio cirúrgico (ISC) é uma importante complicação no pós-operatório de cirurgia cardíaca pediátrica associada ao aumento da morbimortalidade. Objetivos Identificar fatores de risco para a ISC após cirurgias cardíacas para correção de malformações congênitas. Métodos Este estudo caso-controle incluiu 189 pacientes com um ano completo e 19 anos e 11 meses, submetidos à cirurgia cardíaca em hospital universitário terciário de cardiologia de janeiro de 2011 a dezembro de 2018. Foi realizado registro e análise de dados pré, intra e pós-operatórios. Para cada caso foram selecionados dois controles, conforme o diagnóstico da cardiopatia e cirurgia realizada em um intervalo de até 30 dias para minimizar diferenças pré e/ou intraoperatórias. Para a análise dos fatores de risco foi utilizado o modelo de regressão binária logística. Significância estatística definida como valor de p<0,05. Resultados O estudo incluiu 66 casos e 123 controles. A incidência de ISC variou de 2% a 3,8%. Fatores de risco identificados: faixa etária de lactentes (OR 3,19, IC 95% 1,26 - 8,66, p=0,014), síndrome genética (OR 6,20, IC 95% 1,70 - 21,65, p=0,004), RACHS-1 categorias 3 e 4 (OR 8,40, IC 95% 3,30 - 21,34, p<0,001), o valor da proteína C reativa (PCR) de 48 horas pós-operatórias foi demonstrado como fator protetor para esta infecção (OR 0,85, IC 95% 0,73 - 0,98, p=0,023). Conclusão Os fatores de risco identificados não são variáveis modificáveis. Vigilância e medidas preventivas contínuas são fundamentais para reduzir a infecção. O papel do PCR elevado no pós-operatório foi fator protetor e precisa ser melhor estudado.

Abstract Background Surgical site infection is an important complication after pediatric cardiac surgery, associated with increased morbidity and mortality. Objectives We sought to identify risk factors for surgical site infection after pediatric cardiac surgeries. Methods A case-control study included patients aged between 1 year and 19 years and 11 months of age, submitted to cardiac surgery performed at a tertiary cardiac center from January 1 st , 2011, through December 31, 2018. Charts were reviewed for pre-, intra, and postoperative variables. We identified two randomly selected control patients with the same pathophysiological diagnosis and underwent surgery within thirty days of each index case. Univariate and multivariate logistic regression analyses were performed to identify risk factors. Statistical significance was defined as p<0.05. Results Sixty-six cases and 123 controls were included. Surgical site infection incidence ranged from 2% to 3.8%. The following risk factors were identified: Infant age (OR 3.19, 95% CI 1.26 to 8.66, p=0.014), presence of genetic syndrome (OR 6.20, CI 95% 1.70 to 21.65, p=0.004), categories 3 and 4 of RACHS-1 (OR 8.40, CI 95% 3.30 to 21.34, p<0.001), 48 h C-reactive protein level range was detected as a protective factor for this infection (OR 0.85, 95% CI 0.73 to 0.98, p=0.023). Conclusions The risk factors defined in this study could not be modified. Therefore, additional surveillance and new preventive strategies need to be implemented to reduce the incidence of surgical site infection. The increased CRP in the postoperative period was a protective factor that needs further understanding.

Introducción: La atención al paciente con retardo en la cicatrización parte de la optimización en sus cuidados. La reversión del cuadro requiere del conocimiento de los factores de riesgo. La literatura nacional e internacional describen factores locales o relacionados con la herida y generales o relacionados al estado general del paciente. Objetivo: Estimar los factores de riesgo del retardo en la cicatrización en pacientes quemados. Métodos: Estudio analítico de casos y control en pacientes quemados ingresados en el Servicio de Caumatología del Hospital Universitario Manuel Ascunce Domenech en el período 2017 a 2021. La población objeto de estudio comprendió a 267 pacientes. Se calculó el odds ratio y el intervalo de confianza. Resultados: El desarrollo de retardo en la cicatrización resultó tres veces y media más probable en pacientes quemados con 45 años y más, odds ratio 3,591. Además, fue nueve veces más probable en enfermedades crónicas asociadas, hasta seis veces en quemaduras no accidentales, 163 veces en la complicación local y 89 veces en la complicación sistémica. Conclusiones: Los factores de riesgo del retardo en la cicatrización en pacientes quemados identificados fueron los siguientes: edad de 45 años y más, presencia de comorbilidad, el fuego directo como agente causal, el modo de producción no accidental, la presencia de más de seis zonas anatómicas afectadas, la quemadura hipodérmica, la quemadura de 20 porciento de superficie corporal quemada y más de extensión, el apoyo de la lesión, el índice cubano de pronóstico con riesgo vital, la complicación local y la complicación sistémica(AU)

Introduction: The care for the patient with delayed healing starts from the optimization of their care. Reversing such condition requires knowledge of the risk factors. The national and international literature describes local factors related to the injury and general factors related to the patient's general condition. Objective: To estimate the risk factors for delayed healing in burn patients. Methods: An analytical case-control study was carried out with burn patients admitted to the caumatology service at Hospital Universitario Manuel Ascunce Domenech in the period from 2017 to 2021. The study population consisted of 267 patients. Odds ratio and confidence interval were calculated. Results: The development of delayed healing was three and a half times more likely in burn patients aged 45 years or over (odds ratio: 3.591). In addition, it was nine times more likely for associated chronic diseases, up to six times in nonaccidental burns, 163 times in local complications, and 89 times in systemic complications. Conclusions: The identified risk factors for delayed healing in burn patients were the following: age 45 years or over, presence of comorbidity, direct fire as causative agent, nonaccidental way of production, presence of more than six affected anatomical areas, hypodermic burn, burn extension of 20 percent or over on the burned body surface, injury contact pressure, the Cuban index of prognostic vital risk, as well as the local or the systemic complications(AU)

Análisis costo-efectividad del tratamiento con terapia compresiva en la cicatrización de úlceras venosas / Cost-effectiveness analysis of the treatment with compressive therapy in the healing of venous ulcers / Análise de custo-efetividade do tratamento com terapia compressiva na cicatrização de úlceras venosas

Objetivo: analizar el costo-efectividad y calcular la relación costoefectividad incremental del tratamiento multicapa compresivo con respecto al inelástico (bota de Unna y estiramiento corto) según la literatura actual. Método: estudio cuantitativo de costo-efectividad a través de un modelo con ayuda del software TreeAge® para la elaboración del árbol de decisión. Los supuestos anunciados se obtuvieron mediante el uso de datos secundarios de la literatura para estimar el costo y la efectividad de los parámetros asumidos. Para ello, se realizó una revisión sistemática de la literatura con metaanálisis. Resultados: el árbol de decisión, después del Roll Back, mostró que la terapia multicapa prevaleció sobre las alternativas en el caso base, presentó un costo intermedio por aplicación, pero obtuvo la mayor efectividad. El gráfico del análisis de costo-efectividad también demostró que había un dominio extendido de la bota de Unna sobre el vendaje de estiramiento corto. El análisis de sensibilidad reveló que el vendaje multicapa sigue siendo la alternativa con mayor costoefectividad, dentro del umbral de disposición a pagar. Conclusión: la alternativa con mayor costo-efectividad fue el vendaje multicapa, considerado estándar de oro en la literatura. La segunda alternativa con mayor costo-efectividad fue la bota de Unna, la terapia más utilizada en Brasil.

Objective: to analyze the cost-effectiveness and calculate the incremental cost-effectiveness ratio of multilayer compressive treatment in relation to inelastic (Unna boot and short stretch) therapy according to the current literature. Method: quantitative study about cost-effectiveness through modeling with the aid of TreeAge® software for construction of the decision tree. The anticipated assumptions were obtained by using secondary literature data to estimate the cost and effectiveness of the assumed parameters. A systematic literature review with meta-analysis was performed for this end. Results: the decision tree after Roll Back showed that the multilayer therapy dominated the alternatives in the base case, representing an intermediate cost per application, although with the highest effectiveness. The cost-effectiveness analysis graph also showed extended dominance of the Unna boot in relation to the short stretch bandage. The sensitivity analysis showed that multilayer bandage remains a more cost-effective alternative, within the threshold of willingness to pay. Conclusion: the most cost-effective alternative was multilayer bandage, considered the gold standard in the literature. The second most cost-effective alternative was the Unna boot, the most used therapy in Brazil.
