Multimodal analgesia versus patient-controlled analgesia in the management of acute postoperative spinal pain: systematic review and meta-analysis / Analgesia multimodal versus analgesia controlada pelo paciente no tratamento da dor aguda pós-operatória da coluna: revisão sistemática e meta-análise

ABSTRACT BACKGROUND AND OBJECTIVES: Spine diseases have a high annual prevalence and are the main causes of years lived with disability and chronic pain. Among the postoperative analgesic control options, patient-controlled analgesia (PCA) and multimodal analgesia (MMA) have shown good clinical results. This meta-analysis seeks new evidence to help in the treatment of acute postoperative pain in patients undergoing spinal surgery. CONTENTS: The following databases were used: Cochrane Central Register of Controlled Trials, Medline and Embase. Studies that compared two post-surgical analgesic interventions were included; MMA and PCA. The parameters evaluated were: analgesic effect; opioid consumption; length of hospital stay; and adverse effects. Registration of the systematic review protocol: (PROSPERO CRD42023446627). There was no statistical difference when assessing analgesic improvement comparing MMA to PCA (MD -0.12 [-0.41, 0.17] 95%CI with p=0.69). There was a statistical difference, with lower opioid consumption in MMA compared to PCA (MD -3.04 [-3.69, -2.39] 95%CI with p=0.0002). Statistically significant difference regarding length of hospital stay in favor of MMA (MD -13.17 [-16.98, -9.36] 95%CI with p=0.00001), and significantly lower incidence of nausea and vomiting in patients undergoing MMA in compared to PCA (OR 0.26 [0.11, -0.64] 95%CI with p=0.003). CONCLUSION: MMA was equivalent to PCA in the treatment of acute postoperative spinal pain, with the significant clinical advantage and safety of lower amounts of infused opioids, shorter hospital stay and lower incidence of adverse effects.

RESUMO JUSTIFICATIVA E OBJETIVOS: As doenças da coluna apresentam alta prevalência anual e são as principais causas de anos vividos com incapacidade e de cronificação da dor. Dentre as opções de controle analgésico pós-operatória, a analgesia controlada pelo paciente (ACP) e a analgesia multimodal (AMM) apresentam bons resultados clínicos. O objetivo deste estudo foi buscar novas evidências que auxiliem no tratamento da dor aguda no pós-operatório do paciente submetido à cirurgia da coluna. CONTEÚDO: As bases de dados utilizadas: Cochrane Central Register of Controlled Trials, Medline e Embase. Foram incluídos estudos que compararam duas intervenções analgésicas pós-cirúrgicas; AMM e ACP. Os parâmetros avaliados foram: efeito analgésico; consumo de opioide; tempo de internação hospitalar e efeitos adversos. Registro do protocolo de revisão sistemática: (PROSPERO CRD42023446627). Não houve diferença estatística quando avaliadas a melhora analgésica comparando a AMM à ACP (MD -0,12 [-0,41, 0,17] 95%CI com p=0,69). Houve diferença estatística, com menor consumo de opioide na AMM em comparação à ACP (MD -3,04 [-3,69, -2,39] 95%IC com p=0,0002). Diferença estatística significativa com relação ao tempo de permanência hospitalar a favor da AMM (MD -13,17 [-16,98, -9,36] 95%IC com p=0,00001), e incidência significativamente menor de náuseas e vômitos nos pacientes submetidos a AMM em comparação a ACP (OR 0,26 [0,11, -0,64] 95%IC com p=0,003). CONCLUSÃO: A AMM foi equivalente à ACP no tratamento da dor aguda pós-operatória da coluna, com a significativa vantagem clínica e a segurança de menores quantidades de opioides infundidos, menor tempo de internação hospitalar e menor incidência de efeitos adversos.

Combined ultrasound and electric field stimulations improve pain and functional capacity in immediate cesarean delivery: a randomized clinical trial, double-blind, and placebo-controlled / Terapia combinada de estimulação elétrica por meio do ultrassom melhora a dor e a capacidade funcional no pós-parto imediato de cesariana: ensaio clínico randomizado, duplo-cego e placebo

ABSTRACT BACKGROUND AND OBJECTIVES: Wound complications and pharmacological pain relief methods used at the skin surgical site after cesarean delivery may result in women's physical and emotional burden. Thus, nonpharmacological treatments must be explored to avoid these complications and side effects on maternal health. The objective of this study was to investigate the effects of Combined Ultrasound and Electric Field Stimulation (CUSEFS) on cicatricial pain and functional capacity in immediate cesarean delivery. METHODS: This study has a randomized clinical trial, double-blind, and placebo-controlled design. Thirty women (25.7±5.0 years) in immediate postpartum were randomly assigned to three groups: Control (CG, n:9), CUSEFS (TG, n:11), and Placebo (PG, n:10). CUSEFS was performed once for 20 minutes. Cicatricial pain (McGill Pain Questionnaire) and functional capacity (Functional Capacity Check) was assessed at baseline, after the intervention, and after 30 minutes. Cohen's (d) and Mixed-design analysis of variance were used to compare groups. RESULTS: Immediately after the intervention, TG showed a decrease in cicatricial pain compared with CG in sensory (d:3.8 to 4.0), affective (d:4.0), and total categories (d:3.9). In functional capacity, TG had less difficulty than CG at walking (d:0.6) and lying down (d:1.1), and PG at rest (d: 0.9). CONCLUSION: CUSEFS might be a resource for managing cicatricial pain and functional capacity in immediate cesarean delivery. Further studies with longer duration and different CUSEFS doses/parameters are required.

RESUMO JUSTIFICATIVA E OBJETIVOS: As complicações na ferida e o uso de métodos farmacológicos de alívio da dor no local cirúrgico após a cesariana podem resultar em sobrecarga física e emocional para a mulher. Assim, tratamentos não farmacológicos devem ser explorados para evitar essas complicações e efeitos adversos à saúde materna. O objetivo deste estudo foi investigar os efeitos da terapia combinada de estimulação elétrica por meio do ultrassom (CUSEFS) na dor cicatricial e na capacidade funcional no pós-parto imediato de cesariana. MÉTODOS: Este estudo possui um desenho de ensaio clínico randomizado, duplo-cego e controlado por placebo. Trinta mulheres (25,7±5,0 anos) em pós-parto imediato de cesariana foram distribuídas aleatoriamente em três grupos: Controle (CG, n:9), CUSEFS (TG:11) e Placebo (PG, n:10). O CUSEFS foi realizado uma vez por 20 minutos. A dor cicatricial (Questionário de Dor McGill) e a capacidade funcional (Functional Capacity Check) foram avaliadas no início, após a intervenção e após 30 minutos. As análises de variância de design misto e Cohen (d) foram usadas para comparar os grupos. RESULTADOS: Imediatamente após a intervenção, o TG apresentou diminuição na dor cicatricial em relação ao CG nas categorias sensorial (d:3,8 a 4,0), afetiva (d:4,0) e total (d:3,9). Na capacidade funcional, o TG apresentou menor dificuldade que o CG na marcha (d:0,6) e deitado (d:1,1), e que o PG em repouso (d:0,9). CONCLUSÃO: O CUSEFS pode ser um recurso para o manejo da dor cicatricial e da capacidade funcional imediatamente após a cesariana. Além disso, são necessários mais estudos com maior duração e diferentes doses/parâmetros de CUSEFS.

Educación, ejercicio terapéutico y terapia manual en el dolor orofacial. Estudio de casos / Education, therapeutic exercise, and manual therapy approaches in orofacial pain. Case reports

Introducción Los trastornos temporomandibulares son la causa más común de dolor crónico orofacial. Intervenciones pasivas como la terapia manual (TM) es de las herramientas más utilizadas. Sin embargo, este tipo de abordajes puede resultar insuficiente. La investigación de nuevas estrategias, ahora de naturaleza activa, como son el ejercicio o la educación, es necesaria para generar un cambio en la práctica clínica de los profesionales sanitarios y brindar una atención completa al paciente con dolor crónico. Objetivos Analizar el efecto de tres abordajes principales de forma combinada sobre el dolor, factores psicosociales, variables funcionales y biomecánicas. Métodos Se siguió un diseño de estudio de casos compuesto por tres sujetos divididos en tres modelos de intervención: educación para el dolor y terapia manual (PEdu+TM), ejercicio terapéutico y terapia manual (PEjerc+TM) y terapia manual cervical y orofacial (PTM). El periodo de intervención duró 3-4 semanas; las medidas fueron tomadas en tres momentos: preintervención, postintervención inmediata y 45 días postintervención. Dolor, características psicosociales y funcionalidad del paciente fueron evaluadas con diferentes herramientas validadas. Resultados Los resultados mostraron a corto plazo una mejora en todas las variables analizadas en el PEdu+TM y en el PEjerc+TM, pero no en el PTM. A medio plazo (45 días postintervención), el PEdu+TM mostró beneficios en todas las variables estudiadas mientras que el PEjerc+TM generó cambios positivos en las mismas variables excluyendo el dolor. Conclusión El tratamiento combinado podría ser una intervención más eficaz que la terapia manual a solas, siendo necesarios ensayos clínicos aleatorizados que corroboren dichos hallazgos (AU)

Introduction Temporomandibular disorders are the most common cause of chronic orofacial pain. Passive interventions such us manual therapy (MT) is being one of the most used tools. However, this type of approach may be insufficient. The investigation of new strategies, now of an active nature such as exercise or education, it is necessary to generate a change in the clinical practice of health professionals and provide comprehensive care to patients with chronic pain. Objectives To analyze the effect of three main approaches in combination on pain, psychosocial factors, functional and biomechanical variables. Methods A case study design was followed consisting of three subjects divided into three intervention models: pain education and manual therapy (PEdu+TM), therapeutic exercise and manual therapy (PExer+TM), and cervical and orofacial manual therapy (PTM). The intervention period lasted 3-4 weeks, the measurements were taken at three moments: pre-intervention, immediate post-intervention and 45 days post-intervention. Pain, psychosocial characteristics and functionality of the patient were evaluated with different validated tools. Results The results showed in the short-term an improvement in all the variables analyzed in the PEdu+TM and in the PExer+TM, but not in the PTM. In the medium term (45 days post-intervention), the PEdu+TM showed benefits in all the variables studied, while the PExer+TM generated positive changes in the same variables, excluding pain. Conclusion Combined treatment could be a more effective intervention than manual therapy alone, requiring randomized clinical trials to corroborate these findings (AU)

Tratamiento de COVID-19 en Panamá. La historia del inicio, estudio PanaCovid2020

Antecedentes En Panamá, durante los primeros cinco meses de pandemia, se reportaron 65,256 casos y 1,421 fallecimientos por COVID-19. Los tratamientos utilizados en pacientes hospitalizados durante este periodo fueron variando en la medida que surgía evidencia científica. Metodología Presentamos un estudio multicéntrico observacional, descriptivo, de corte transversal y retrospectivo de la terapéutica administrada en pacientes hospitalizados con COVID-19 en siete centros estatales de la República de Panamá, entre el 1 de marzo al 31 de julio de 2020. Se analizó el resultado de recuperado o fallecido en relación al uso de hidroxicloroquina, heparinas y esteroides. Resultados Se revisaron 837 expedientes. 60.7% pacientes eran hombres y la mediana de edad fue 53.6 años. Los tratamientos más utilizados fueron heparinas 84.7%, esteroides sistémicos 76.5%, azitromicina 65.5% e hidroxicloroquina en 41.1%. La frecuencia de uso de oxigenoterapia fue de cánula nasal 73,2%, máscara facial con reservorio 39%, cánula de alto flujo 8.9%, ventilación mecánica no invasiva 11.1% y ventilación invasiva en el 15.3%. Los esteroides mostraron mayor tasa de recuperación (OR 1.72 [1.16-2.54). Conclusiones El reto de abordar una nueva enfermedad, sin tratamiento conocido, con evolución y desenlace variable, llevó a la comunidad médica a utilizar medicamentos empíricos con potencial terapéutico incierto. Destacamos que desde muy temprano se administró esteroides sistémicos, heparinas y tocilizumab; actualmente con beneficios para pacientes con requerimientos de hospitalización. Además, se empleó técnicas de oxigenación, como la cánula de alto flujo y ventilación mecánica no invasiva, con dudosa efectividad; pero que hoy ya tienen un rol estudiado en la falla respiratoria por COVID-19.

Background: In Panama, during the first five months of the pandemic, 65,256 cases and 1,421 deaths due to COVID-19 were reported. The treatments used in hospitalized patients during this period varied as scientific evidence emerged. Methodology: We present a retrospective, descriptive, cross-sectional, observational, descriptive, multicenter study of the therapeutics administered in hospitalized patients with COVID-19 in seven state centers in the Republic of Panama, between March 1 and July 31, 2020. The outcome of recovered or deceased was analyzed in relation to the use of hydroxychloroquine, heparins and steroids. Results: A total of 837 files were reviewed. 60.7% of patients were men and the median age was 53.6 years. The most commonly used treatments were heparins 84.7%, systemic steroids 76.5%, azithromycin 65.5% and hydroxychloroquine in 41.1%. The frequency of oxygen therapy use was nasal cannula 73.2%, face mask with reservoir 39%, high-flow cannula 8.9%, noninvasive mechanical ventilation 11.1% and invasive ventilation in 15.3%. Steroids showed higher recovery rate (OR 1.72 [1.16-2.54). Conclusions: The challenge of dealing with a new disease, without known treatment, with variable evolution and outcome, led the medical community to use empirical drugs with uncertain therapeutic potential. We highlight the early administration of systemic steroids, heparins and tocilizumab; currently with benefits for patients requiring hospitalization. In addition, oxygenation techniques were used, such as high-flow cannula and noninvasive mechanical ventilation, with doubtful effectiveness, but which today have a studied role in respiratory failure due to COVID-19.   (provided by Infomedic International)

Nanoformulaciones avanzadas contra la infección bacteriana / Advanced nanoformulations against bacterial infection

En la actualidad, los antibióticos constituyen la piedra angular en el tratamiento de las infecciones bacterianas. Sin embargo, en las últimas décadas, las bacterias han desarrollado mecanismos de defensa que las hace altamente resistentes a los antibióticos existentes, lo que nos deja vulnerables frente a las infecciones. La Organización Mundial de la Salud alerta de que las resistencias bacterianas constituyen una grave amenaza para la toda la humanidad y que necesitamos urgentemente el desarrollo de nuevos antibacterianos. La nanotecnología ha irrumpido en este escenario proporcionando herramientas novedosas para el diagnóstico, prevención y tratamiento de numerosas patologías, principalmente el cáncer. De este modo, la nanomedicina permite abordar diferentes enfermedades utilizando nanotransportadores de fármacos capaces de dirigirse de forma selectiva a la diana terapéutica, aumentando así la eficacia del tratamiento y disminuyendo los efectos secundarios. Este discurso se centra en las nanopartículas mesoporosas de sílice (MSNs), cuyas propiedades únicas y enorme versatilidad permiten diseñar múltiples nanosistemas para tratar infecciones bacterianas. Su capacidad para dirigirse específicamente a las bacterias y/o al biofilm, liberar distintos fármacos de manera controlada y/o inteligente en respuesta a determinados estímulos, e incorporar cationes terapéuticos en terapias combinadas, auguran el desarrollo de nanoformulaciones avanzadas que podrían revolucionar la lucha contra la infección bacteriana. (AU)

Nowadays, antibiotics remain the cornerstone in the treatment of bacterial infections. However, in recent decades, bacteria have developed defense mechanisms that make them highly resistant to the existing antibiotics, leaving us vulnerable to infection. The World Health Organization warns that bacterial resistance constitutes a serious threat to humanity at global level and that there is an urgent need of developing new antibacterial agents. Nanotechnology has entered into this scenario by providing novel tools for the treatment of numerous pathologies, highlighting cancer. Nanomedicine brings up the opportunity to address different diseases using drug nanocarriers that can be specifically directed to the therapeutic target, increasing the efficacy of the treatment and reducing the side effects. This entrance speech focuses on mesoporous silica nanoparticles, whose unique properties and enormous versatility allow the design of multiple nanosystems to treat bacterial infections. Its ability to specifically target bacteria and/or biofilm, release different drugs in a controlled manner and/or in a smart fashion, i.e. in response to certain stimuli, and incorporate therapeutic cations for combined therapies, envision the development of advanced nanoformulations that could revolutionize the fight against bacterial infection.

Chronic postsurgical pain after emergency cervical fusion with iliac crest graft - a multimodal approach to a multifactorial problem. Case report / Dor crônica pós-operatória após artrodese cervical emergencial com enxerto de crista ilíaca - abordagem multimodal para um problema multifatorial. Relato de caso

ABSTRACT BACKGROUND AND OBJECTIVES: Chronic postsurgical pain is a major surgical complication with an impact on quality of life. Persistent pain following cervical fusion with iliac crest graft can be due to patient positioning, cervical surgical technique or nerve injury during iliac crest harvesting. Treatment options for chronic postsurgical pain overlap with those recommended for neuropathic pain. However, other pain mechanisms may be present in these patients. CASE REPORT: Male patient, 51-year-old, with persistent pain five years after emergency cervical arthrodesis with an iliac crest graft. The patient was referred to the chronic pain department (CPD) for management of meralgia paresthetica. However, other significant pain etiologies were found and treated such as nociceptive neck pain, myofascial lumbar pain, and inguinal neuropathic postsurgical pain. The therapeutic approach included multimodal pharmacotherapy with anticonvulsants, antidepressants, weak opioids, topical capsaicin 8% patch, as well as nerve blocks. After almost two years of follow-up, CPD discharge was possible, with minimal pain and return to baseline activity. CONCLUSION: Although the patient had a long course of undertreated postsurgical pain, a multimodal approach targeting different pain etiologies allowed the achievement of satisfactory pain control and return to baseline physical activity.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor crônica pós-operatória é uma importante complicação cirúrgica com impacto na qualidade de vida. A dor persistente após artrodese cervical pode ser secundária ao posicionamento do paciente, abordagem cirúrgica cervical ou lesão nervosa durante colheita de enxerto ilíaco. As opções terapêuticas para dor crônica pós-operatória têm alguma sobreposição com o tratamento da dor neuropática. No entanto, outros mecanismos de dor podem estar presentes nestes pacientes. RELATO DO CASO: Paciente do sexo masculino, 51 anos, que se apresentou com dor persistente cinco anos após artrodese cervical emergencial, com enxerto de crista ilíaca. Foi encaminhado para a unidade de dor crônica (UDC) para abordagem de meralgia parestésica. No entanto, foram encontradas e tratadas outras etiologias de dor: dor cervical nociceptiva; dor lombar miofascial e dor neuropática pós-operatória inguinal. A abordagem terapêutica utilizada incluiu farmacoterapia com anticonvulsivantes, antidepressivos e opioides fracos, adesivo de capsaicina a 8% e bloqueios regionais. Após quase dois anos de seguimento, foi possível oferecer alta da UDC com queixas álgicas mínimas e retorno da atividade física basal. CONCLUSÃO: Apesar de o paciente ter passado por um longo período sob tratamento insuficiente de dor pós-operatória, uma abordagem multimodal tendo como alvo diferentes etiologias de dor permitiu obter um controle álgico satisfatório e o retorno à atividade física basal.

The Impact of Leprosy on the Quality of Life of Patients Undergoing Treatment / O Impacto da Hanseníase na Qualidade de Vida dos Pacientes em Fase de Tratamento

The individuals with Hansen's disease experience situations of prejudice that, together with stigma and discrimination, culminate in social isolation and restrictions in social relationships. The aim of this study was to assess the perception of leprosy patients about their quality of life. This is a cross-sectional, quantitative study, whose convenience sample consisted of 94 leprosy patients, undergoing treatment, who attended health units in the city of Cuiabá, MT, Brazil. A structured questionnaire with sociodemographic data and information about the patient's knowledge about leprosy, prejudice, self-esteem and quality of life, was applied between April and August 2018.The results showed in the investigated population a predominance of males (55.3%), individuals with high school education (28.7%) and with an income ranging from 1 to 3 minimum wages (67%).The interviewees pointed out the side effects (44.7%) and the duration period (28.7%) as the greatest difficulty in the treatment. Most of the investigated (72.3%) had great knowledge about the disease, among which 26.6% had already suffered the leprosy reaction.40.4% of individuals were depressed and sad, and 69.1% had problems in employment after the diagnosis of the disease. When the quality of life was investigated, 45.7% of leprosy patients classified the domains evaluated between bad and very bad. Physical pain was associated with 43.7% of the individuals being unable to perform daily tasks. It can be concluded that leprosy causes suffering beyond pain and discomfort, with great social and psychological impact. (AU)

Os pacientes com hanseníase vivenciam situações de preconceito que, com o estigma e a discriminação, culminam para o isolamento social e a restrição dos relacionamentos sociais. O objetivo do presente estudo foi avaliar a percepção do paciente com hanseníase sobre sua qualidade de vida. Trata-se de um estudo transversal, quantitativo, cuja amostra de conveniência foi composta por 94 pacientes hansenianos, em fase de tratamento, que frequentavam as Unidades de Saúde do município de Cuiabá/MT, Brasil. Um questionário estruturado com dados sociodemográficos e informações sobre o conhecimento do paciente sobre a hanseníase, preconceito, autoestima e qualidade de vida, foi aplicado entre abril e agosto de 2018. Os resultados mostraram, na população investigada, um predomínio de indivíduos do sexo masculino (55,3%), com ensino médio completo (28,7%) e com renda entre 1 e 3 salários mínimos (67%). Os entrevistados apontaram como maior dificuldade do tratamento os efeitos colaterais (44,7%) e o período de duração (28,7%). A maioria dos investigados (72,3%) apresentava grande conhecimento sobre a doença, dentre os quais 26,6% já haviam sofrido a reação hansênica. 40,4% dos indivíduos encontravam-se deprimidos e tristes e 69,1%, tiveram problemas no emprego após o diagnóstico da doença. Quando a qualidade de vida foi investigada, 45,7% dos hansenianos classificaram os domínios avaliados entre ruim e muito ruim. A dor física foi associada ao impedimento do desempenho das tarefas diárias por 43,7% dos indivíduos. Pode-se concluir que a hanseníase causa sofrimento aos indivíduos que ultrapassa a dor e o mal-estar estritamente vinculados ao prejuízo físico, com grande impacto social e psicológico. (AU)

Experts document on methotrexate use in combined therapy with biological or targeted synthetic disease modifying drugs in patients with rheumatoid arthritis.

OBJECTIVE: We aimed to develop recommendations for the management of methotrexate (MTX) when considering the combination with biological (b) or targeted synthetic (ts) disease modifying drugs (DMARDs) in rheumatoid arthritis (RA). METHODS: Eleven experts on RA were selected. Two coordinators formulated 13 questions about the combination therapy of MTX with bDMARDs or tsDMARDs. A systematic review was conducted to answer the questions. Inclusion and exclusion criteria were established as well as the search strategies (Medline, Embase and the Cochrane Library were searched up to January 2019). Two reviewers selected the articles and collected data. Simultaneously, EULAR and ACR meeting abstracts were evaluated. Based on this evidence, the coordinators proposed preliminary recommendations that the experts discussed and voted in a nominal group meeting. The level of evidence and grade of recommendation was established using the Oxford Center for Evidence Based Medicine and the level of agreement with a Delphi. Agreement was established if at least 80% of the experts voted 'yes' (yes/no). RESULTS: The systematic review retrieved 513 citations of which 61 were finally included. A total of 10 recommendations were generated, voted and accepted. The level of agreement was very high in all of them and it was achieved in the first Delphi round. Final recommendations cover aspects such as the optimal MTX dosage, tapering strategy or patients' risk management. CONCLUSIONS: This document is intended to help clinicians solve usual clinical questions and facilitate decision making when treating RA patients with MTX in combination with bDMARDs or tsDMARDs.

Microagulhamento do couro cabeludo como terapia complementar no tratamento da alopecia de padrão feminino / Scalp microneedling as a complementary therapy for female pattern hair loss

A alopecia de padrão feminino figura dentre as queixas mais frequentes no consultório dermatológico e afeta até 50% das mulheres no climatério e na pós-menopausa. Apesar da existência de múltiplas terapias hoje disponíveis, algumas pacientes mostram-se refratárias aos tratamentos convencionais, sendo necessária a associação de tratamentos de segunda linha para a obtenção de bons resultados estéticos. Este trabalho ilustra as vantagens do microagulhamento nesse cenário por meio do relato de uma paciente de 48 anos de idade que não apresentou boa resposta clínica à associação do minoxidil tópico e à finasterida oral.

Female pattern hair loss (FPHL) is one of the most frequent complaints in dermatological practice. It affects up to 50% of climacteric and postmenopausal women. Despite multiple therapies available nowadays, some patients are refractory to conventional treatments, requiring the association of second-line therapies to obtain good aesthetic results. This paper aims to show the advantages of microneedling of the scalp for such cases by reporting the case of a 48-years-old patient who failed to the association of topical minoxidil and oral finasteride therapy

Costoefectividad del régimen combinado de mirabegron/solifenacina en el tratamiento del síndrome de vejiga hiperactiva en Colombia / Cost-effectiveness of the Combined Regimen of Mirabegron/Solifenacin in the Treatment of Overactive Bladder Syndrome in Colombia

Objetivo Evaluar la costoefectividad incremental del régimen combinado de mirabegron/solifenacina en comparación con el uso temprano de toxina botulínica, desde la perspectiva del sistema de salud colombiano, para el tratamiento de adultos con vejiga hiperactiva. Métodos Se empleó un modelo de Markov en que se comparan dos secuencias de tratamiento, una con y otra sin mirabegron/solifenacina, para evaluar la costoefectividad en un horizonte temporal de cinco años. Debido a la perspectiva de análisis, sólo se tuvieron en cuenta los costos médicos directos. La eficacia del tratamiento evaluado y su comparador fue medida en términos de la reducción de episodios diarios de incontinencia y de la frecuencia de micciones. Los costos fueron expresados en pesos colombianos de 2019, y se aplicó una tasa de descuento de 5% tanto para desenlaces como para costos. Resultados Para el caso base, el costo del tratamiento en la secuencia que incluye mirabegron/solifenacina fue mayor, pero generó un mayor número de años de vida ajustados por calidad, y así e obtuvo una razón de costoefectividad incremental de $13.637,184 si se considera el desenlace de reducción de episodios diarios de incontinencia de 50%, y de $29.313,848 si se considera el del 100%. Conclusiones De acuerdo con los resultados de esta evaluación, para un horizonte de análisis de cinco años, la secuencia de tratamiento con mirabegron/solifenacina es una alternativa costoefectiva, si se considera un umbral de disposición a pagar de tres veces el producto interno bruto (PIB) per cápita.

Aim To evaluate the incremental cost-effectiveness of the combined regimen of mirabegron/solifenacin compared with the early use of botulinum toxin, from the perspective of the Colombian health system, for the treatment of adults with overactive bladder. Methods A Markov model comparing two treatment sequences, one with and one without mirabegron/solifenacin, was used to assess cost-effectiveness over a five-year period. Due to the perspective of the analysis, only direct medical costs were considered. The efficacy of the evaluated treatment and its comparator was measured in terms of the reduction in the daily incontinence episodes and the frequency of micturition. The costs were expressed in Colombian pesos of 2019, and a discount rate of 5% was applied for both outcomes and costs. Results For the base case, the cost of the treatment in the sequence that includes mirabegron/solifenacin was higher, but it generated a greater number of quality-adjusted years of life, thus obtaining an incremental cost-effectiveness ratio of $13,637,184 when considering the outcome of 50% of reduction in the daily incontinence episodes, and $29,313,848 when considering 100%. Conclusions According to the results of the present assessment, for a five-year period of analysi, the mirabegron/solifenacin treatment sequence is a cost-effective alternative when considering a threshold of willingness to pay three times the per capita gross domestic product (GDP).

Resultados: se incluyeron 31 pacientes; la edad mediana al diagnóstico fue 76,8 años; las características clínico-patológicas fueron: carcinoma ductal: 71%; GH 1-2: 74,2%; estadio I: 54,8 %; sin metástasis axilares: 80,6 %; HER2-RE/RP+ 80,6%; HER2+ 16,7%, y triple negativas 3,2%. El 29% de las pacientes fueron diagnosticadas mediante tamizaje poblacional y el 74,2% recibieron tratamiento según pautas vigentes, mientras que el 38,7% fueron subtratadas y el 16,1% sobretratadas. La mediana de SVG fue de 98,7 meses. Conclusiones: Una minoría de las pacientes fue diagnosticada mediante tamizaje poblacional, el tipo histológico más frecuente fue el ductal y la prevalencia de los tumores HER2-RE/RP+ fue mayor que en las pacientes más jóvenes. La mayoría de las pacientes recibió tratamiento estandar.

Introduction: There are few guidelines for the treatment of breast cancer (BC) in older patients, which can lead to under- or over-treatment. Objective: To understand the characteristics, management and evolution of early BC in older women. Material and methods: Observational, descriptive, cross-sectional study. Data were collected on the clinical-pathological characteristics and evolution of patients aged 70 years or older, treated for BC in the period from 1/1/ 2011 to 31/12/ 2018, at the Hospital de Clínicas. Descriptive statistical tools were used and the Kaplan-Meier method was applied to calculate the overall survival (OS) rate. Results: 31 patients were included; median age at diagnosis was 76.8 years old; the clinical-pathological characteristics were: ductal carcinoma: 71%; HG 1-2: 74.2%; stage I: 54.8%; no axillary metastases: 80.6%; HER2-ER/PR+ 80.6%; HER2+ 16.7%, and triple negative 3.2%. Of all the patients, 29% were diagnosed through screening and 74.2% were treated according to current guidelines, while 38.7% were under-treated and 16.1% over-treated. The median OS was 98.7 months. Conclusions: A minority of patients were diagnosed by screening, the most frequent histological type was ductal and the prevalence of HER2-RE/RP+ tumors was higher than in younger patients. Most patients received standard treatment.
