Retrospective review of medicine utilization for noncommunicable diseases in three public sector pharmacies in Jamaica / Revisión retrospectiva del uso de medicamentos para enfermedades no transmisibles en tres farmacias del sector público de Jamaica / Revisão retrospectiva do uso de medicamentos para doenças não transmissíveis em três farmácias da rede pública na Jamaica

ABSTRACT Objective. The rational use of medicines offers a cost-saving strategy to maximize therapeutic outcomes for developing and developed countries. The aim of this study was to evaluate the rational use of medicines for selected noncommunicable diseases (NCDs) at three pharmacies at public hospitals in Jamaica using the World Health Organization's (WHO's) prescribing indicators. Methods. In this retrospective cross-sectional study, prescriptions for adult outpatients containing at least one medicine for cardiovascular disease, diabetes, cancer, chronic obstructive pulmonary disease or asthma that were filled between January and July 2019 were reviewed using WHO's prescribing indicators for the rational use of medicines. Data were analyzed and expressed as descriptive and inferential statistics. For all analyses conducted, significance was determined at P < 0.05. Results. A total of 1 500 prescriptions covering 5 979 medicines were reviewed; prescriptions were mostly written for female patients aged 42-60 years. Polypharmacy was observed in 35.6% (534) of prescriptions, and there was an average of 4 medicines per prescription, with a maximum of 17. Most of the prescriptions at each site were filled, with the main reason for not dispensing a medicine being that it was out of stock. Generic prescribing was high for all sites, accounting for more than 95% (5 722) of prescribed medicines. There was full compliance with prescribing according to the WHO Model List of Essential Medicines at two of the sites, but it was just off the target at Site 1, by 1.4%. Conclusions. The WHO guidelines for the rational use of medicines were followed with respect to the proportion of medicines prescribed from the WHO Model List and the proportion of antibiotics prescribed. The number of medicines per prescription and the proportion of medicines prescribed by generic name did not meet the WHO criteria. However, prescribing was aligned with treatment guidelines for the selected NCDs.

RESUMEN Objetivo. El uso racional de los medicamentos proporciona una estrategia de ahorro de costos para maximizar los resultados terapéuticos tanto en los países en desarrollo como en los países desarrollados. El objetivo de este estudio fue evaluar el uso racional de medicamentos para algunas enfermedades no transmisibles (ENT) seleccionadas en tres farmacias de hospitales públicos de Jamaica, usando los indicadores de prescripción de la Organización Mundial de la Salud (OMS). Métodos. En este estudio transversal retrospectivo se examinaron las prescripciones realizadas a pacientes ambulatorios adultos que incluían al menos un medicamento para enfermedades cardiovasculares, diabetes, cáncer, enfermedad pulmonar obstructiva crónica o asma, dispensadas entre enero y julio del 2019, utilizando los indicadores de prescripción para el uso racional de medicamentos de la OMS. Los datos se analizaron y expresaron mediante estadística descriptiva e inferencial. Para todos los análisis realizados se estableció un nivel de significación de p <0,05. Resultados. Se examinó un total de 1 500 prescripciones que incluían 5 979 medicamentos; la mayor parte de ellas correspondían a pacientes de sexo femenino de 42 a 60 años. Se observó que había polimedicación en el 35,6% (534) de las prescripciones, con un promedio de 4 y un máximo de 17 medicamentos por receta. En todos los centros se dispensó la mayor parte de los medicamentos prescritos, y el motivo principal para no hacerlo fue la falta de existencias del medicamento en cuestión. La prescripción de genéricos fue elevada en todos los centros y supuso más del 95% (5 722) de los medicamentos prescritos. En dos centros la prescripción se realizó en su totalidad de acuerdo con la Lista Modelo de Medicamentos Esenciales de la OMS, pero en el centro 1 no se alcanzó el objetivo por un 1,4%. Conclusiones. Se siguieron las directrices de la OMS para el uso racional de medicamentos en cuanto a la proporción de medicamentos prescritos de la Lista Modelo de la OMS y la proporción de antibióticos prescritos. El número de medicamentos por receta y la proporción de medicamentos prescritos mediante su nombre genérico no cumplieron con los criterios de la OMS. Sin embargo, las prescripciones estaban en consonancia con las directrices de tratamiento de las enfermedades no transmisibles seleccionadas.

RESUMO Objetivo. O uso racional de medicamentos é uma estratégia de contenção de custos para maximizar os resultados terapêuticos em países desenvolvidos e em desenvolvimento. O objetivo deste estudo foi avaliar o uso racional de medicamentos para algumas doenças não transmissíveis selecionadas em três farmácias de hospitais públicos na Jamaica a partir dos indicadores de prescrição preconizados pela Organização Mundial da Saúde (OMS). Métodos. Estudo transversal retrospectivo que avaliou receitas médicas de pacientes ambulatoriais adultos contendo pelo menos um medicamento prescrito para doença cardiovascular, diabetes, câncer, doença pulmonar obstrutiva crônica ou asma e dispensadas entre janeiro e julho de 2019. A avaliação foi realizada a partir dos indicadores de prescrição preconizados pela OMS para o uso racional de medicamentos. Os dados obtidos foram analisados por meio de estatísticas descritivas e inferenciais. O nível de significância de p <0,05 foi adotado em todas as análises. Resultados. Ao todo, foram analisadas 1 500 receitas médicas compreendendo 5 979 medicamentos. Em sua maioria, as receitas foram prescritas para pacientes do sexo feminino com idades entre 42 e 60 anos. A polifarmácia foi observada em 35,6% (534) das receitas; em média, foram prescritos 4 medicamentos, até um máximo de 17. As farmácias estudadas dispensaram a maior parte dos medicamentos receitados. O principal motivo para não fornecer algum medicamento foi o desabastecimento. O percentual de medicamentos genéricos foi alto em todos os locais, representando mais de 95% (5 722) do volume receitado. Houve plena observância da Lista Modelo de Medicamentos Essenciais da OMS nas receitas analisadas em dois dos locais estudos, e observância quase completa (diferença de 1,4%) no local 1. Conclusões. As diretrizes da OMS de uso racional de medicamentos foram cumpridas no que se refere ao percentual de medicamentos receitados de acordo com a Lista Modelo da OMS e o percentual de antibióticos receitados. Os critérios da OMS não foram cumpridos quanto ao número de medicamentos por receita e ao percentual receitado usando o nome genérico. Porém, os medicamentos foram receitados de acordo com as diretrizes terapêuticas para as doenças não transmissíveis selecionadas.

Traqueostomía abierta en el sistema de salud de Malvinas Argentinas. Nuestra Experiencia / Open tracheostomy in Malvinas Argentinas health system. Our experience

Introducción: la traqueostomía es la abertura y el abocamiento de la tráquea al exterior realizada para lograr una vía aérea controlable y permeable. El abordaje puede ser percutáneo y abierto, bajo anestesia general o local, de forma urgente o programada. Objetivo: describir la técnica quirúrgica realizada habitualmente en el sistema de salud de Malvinas Argentinas y evaluar indicaciones y complicaciones. Materiales y métodos: estudio descriptivo retrospectivo que incluyó pacientes con traqueostomía, mayores de 18 años, sin distinción de sexo, realizada entre enero de 2015 y junio de 2018 en Malvinas Argentinas. Resultados: se operaron 72 pacientes, 11 anestesia local y 61 anestesia general; 15 urgencias y 57 programados. La edad promedio fue 34,7. La técnica utilizada fue abierta con incisión horizontal. Las principales indicaciones: intubación orotraqueal prolongada en 34 pacientes, síndrome obstructivo laríngeo agudo (SOLA) en 25 y destete dificultoso en 6. Las complicaciones más frecuentes: lesiones laringotraqueales en 9 pacientes, infección de herida quirúrgica en 5 y enfisema subcutáneo en 3. Discusión: la técnica abierta no es la única existente en la bibliografía, pero buenos resultados en nuestro servicio afirman su seguridad por mejor reconocimiento de estructuras anatómicas y abocamiento de la tráquea. No es posible concluir cuál técnica es superior con respecto a morbimortalidad. Existen diferencias en el lugar donde se realiza, y puede hacerse en quirófano o junto a la cama del paciente con adecuada asepsia. Conclusión: en la actualidad sigue siendo la técnica de elección para la realización de este procedimiento en nuestro servicio.

Introduction: Tracheostomy is the opening and entrance of the trachea to the outside carried out to achieve a controllable and patent airway. The approach can be percuta-neous and open, under general or local anesthesia, urgently or scheduled. Objective:Describe the surgical technique usually performed in Malvinas Argentinas Health System and evaluate indications and complications. Materials and methods: Retros-pective descriptive study, including of patients with tracheostomy, over 18 years of age, without distinction of sex, carried out between January 2015 and June 2018, in Malvinas Argentinas. Results: 72 patients underwent surgery, 11 local anesthesia, 61 general; 15 emergency, and 57 scheduled. Average age 34.7. The technique used was open with a horizontal incision. The main indications were prolonged orotra-cheal intubation in 34 patients, acute laryngeal obstructive syndrome (AOLS) in 25, and difficult weaning in 6. The most frequent complications were laryngotracheal injuries in 9 patients, surgical wound infection in 5, and subcutaneous emphysema in 3. Discussion: Open technique is not the only one existing in the literature, but the good results in our service confirm its safety due to better recognition of anatomical structures and opening of the trachea. It is not possible to conclude which technique is superior, with respect to morbidity and mortality. There are differences in the place where it is performed, and it can be done in the operating room or next to the patient's bed with adequate asepsis. Conclusion: Currently, it continues to be the technique of choice for performing this procedure in our service.

Alimentos sin finalidad nutricional en la terapéutica médica hospitalaria de la edad moderna en el Hospital de Santiago de Vitoria (Álava, España) / Food without nutritional purpose in the medical therapeutics in the modern age at Hospital de Santiago in Vitoria (Alava, Spain)

Introduction: although important, food in medieval and modern hospitals was far from the excellence and abundance suggested by somehistorians, probably due to an incorrect assessment of hospital documentation, considering all food expenditure to be for food when much of itwas destined for the apothecary’s shop.Aim/method: to identify the foodstuffs used for non-nutritional therapeutic purposes during the modern age at Hospital de Santiago in Vitoria(Alava, Spain), to describe the system of consignment, and to review the bibliography of the period in order to facilitate documentary assessmentstrategies for researchers.Results: between 1592 and 1813, 42 groups of foodstuffs acquired for non-nutritional therapeutic purposes were identified. The system of annotation in the expenditure books is neither systematic nor homogeneous, but highly variable and dependent on who made the entry. Twenty-seventerms were identified for the recognition that a given foodstuff was intended for the apothecary’s shop and not the kitchen. Fourteen sanitarytexts of the period were chosen as clarifying bibliography, finding the 17th century nursing manuals most useful for the proposed purposes.Conclusions: the variety and quantity of foodstuffs destined for the apothecary’s shop shows the risk of confusion in unfamiliar researcherswhen analysing hospital diets from account books. A proposal of terms and strategies for discriminating the nutritional or non-nutritional use ofthe food acquired, together with bibliographical recommendations, is essential for an adequate assessment of historical hospital diets.

Description of the S-Apple mixed rotation and transposition flap: preliminary note / Descrição do retalho misto de rotação e transposição S-Apple: nota prévia

Introduction: The flaps, whose function is to reduce or redirect tension during a closure, are classified based on their primary movement: transposition, advancement, and rotation, each with its characteristics, indications, and peculiarities. Combining the qualities of the transposition flaps with those of rotation, which make up the S-Apple flap, makes it more versatile and with better aesthetic results than the bilobed flap, which denotes the archetype for the appearance of the S-Apple. Method: Having the rotation and transposition flaps as an archetype, four flaps are made in the S-Apple flap, which are rotated and transposed to close the defect. This is excised in a circular format for the oncological safety of margins. The "S" of the flap is traced at a 30º angle in relation to the defect. The arm dimension must be the same diameter as the defect, with the flaps transposed as in a z-plasty, and the flap rotated to cover the defect, resulting from the exeresis of the lesion. Results: No necrosis, infection, dehiscence, recurrences, trapdoor scars, or rotation point elevation were observed. The scars were classified as satisfactory and extremely satisfactory. Conclusion: The S-Apple flap proved versatile and easy to mark with excellent aesthetic and functional results.

Introdução: Os retalhos, com função de reduzir ou redirecionar a tensão durante um fechamento, são classificados com base em seu movimento primário: transposição, avanço e rotação, cada um com suas características, indicações e peculiaridades. O arregimentar das qualidades dos retalhos de transposição com os de rotação, que compõem o retalho S-Apple, tornam-no mais versátil e com melhores resultados estéticos em relação ao retalho bilobado, que denota o arquétipo para o surgimento do S-Apple. Método: Tendo como arquétipo os retalhos de rotação e transposição, no retalho S-Apple são confeccionados quatro retalhos, que são rotacionados e transpostos para fechamento do defeito. Este é excisado em formato circular para segurança oncológica de margens. O "S" do retalho é traçado em um ângulo de 30º em relação ao defeito. A dimensão do braço deve ser do mesmo diâmetro do defeito, sendo os retalhos transpostos como em uma zetaplastia e o retalho rotacionado para cobrir o defeito, resultante da exérese da lesão. Resultados: Não foram observadas necroses, infecção, deiscências, recidivas, cicatrizes em alçapão e elevação em ponto de rotação. As cicatrizes foram classificadas como satisfatórias e extremamente satisfatórias. Conclusão: O retalho S-Apple se mostrou um retalho versátil de fácil marcação com excelentes resultados estéticos e funcionais.

Direct costs of treating men with prostate cancer with High Intensity Focused Ultrasound / Costos directos del tratamiento de hombres con cáncer de próstata con el uso de High Intensity Focused Ultrasound / Custos diretos do tratamento de homens com câncer de próstata via High Intensity Focused Ultrasound

ABSTRACT Objective: To analyze the direct costs of materials, medicines/solutions and healthcare professionals required to treat men with prostate cancer using High Intensity Focused Ultrasound. Method: Quantitative, exploratory-descriptive research, single case study type. Data were collected from electronic medical records/printed documentation from the Operating Room of a public teaching and research hospital. Health professionals estimated the respective time spent on activities in the following stages: "Before anesthetic induction", "Before performing thermal ablation", "During thermal ablation" and "After performing thermal ablation". Costs were calculated by multiplying the (estimated) time spent by the unit cost of direct labor, adding to the measured cost of materials, medicines/solutions. Results: The measured costs with materials corresponded to US$851.58 (SD = 2.17), with medicines/solutions to US$72.13 (SD = 25.84), and estimated personnel costs to US$196.03, totaling US$1119.74/procedure. Conclusion: The economic results obtained may support hospital managers in the decision-making process regarding the adoption of the High Intensity Focused Ultrasound for the treatment of prostate cancer.

Suplementação de vitamina C: o que mostram as revisões sistemáticas Cochrane? / Vitamin C supplementation: what do Cochrane systematic reviews show?

Contextualização: A vitamina C (ácido ascórbico) é, sem dúvida, a mais popular dentre as vitaminas e a vedete de vendas na mídia, sobretudo no inverno, sob o slogan de que previne doenças. Objetivos: O estudo avaliou a efetividade da suplementação de vitamina C para tratamento e prevenção de sintomas e doenças, segundo as revisões sistemáticas da Colaboração Cochrane. Métodos: Trata-se de overview de revisões sistemáticas Cochrane. Procedeu-se à busca na Cochrane Library (2022), sendo utilizado o termo "Ascorbic Acid". O desfecho primário de análise foi a redução da incidência da doença ou a melhora clínica, mediante suplementação de vitamina C. Resultados: A estratégia de busca recuperou 26 revisões sistemáticas Cochrane, sendo oito estudos incluídos, seguindo critérios de inclusão. Foram avaliados 91 ensaios clínicos (n = 54.864 participantes). Condições/doenças fetais, pneumonia, resfriado comum, tétano, doença cardiovascular, asma e broncoconstrição por exercício, retinopatia diabética e Doença de Charcot-Marie-Tooth configuraram objetos de análise. Não foi evidenciada efetividade da vitamina C nas análises dessas condições. Discussão: Não há evidência de efetividade da vitamina C para as doenças analisadas. Embora a maioria dos estudos primários tenha limitações sérias e a evidência seja de baixa qualidade, não é possível recomendar a suplementação da vitamina C para essas condições nesse momento. Conclusão: Não há efetividade, nesse momento, da suplementação da vitamina C para prevenção e tratamento de doenças analisadas pela Cochrane, A evidência é bastante limitada e recomenda-se a realização de novos ensaios clínicos randomizados, utilizando-se o CONSORT (Consolidated Standards of Reporting Trials) Statement.

Cannabis medicinal: puntos críticos para su uso clínico / Medical cannabis: Critical points for clinical application

El cannabis se ha utilizado desde la antigüedad con fines recreativos y medicinales. Es una fuente muy rica de compuestos químicos, la mayoría denominados fitocannabinoides, que tienen una variedad de efectos fisiológicos, principalmente por su unión a receptores cannabinoides endógenos como el CB1 y CB2, entre otros. El cannabis tiene propiedades terapéuticas potenciales y sus preparaciones se han utilizado como remedios tradicionales para tratar el dolor y la emesis. Los cannabinoides sintéticos se utilizan clínicamente como analgésicos, antiespasmódico, antieméticos y estimulantes del apetito. La toxicidad significativa del cannabis es poco común en los adultos, sin embargo, puede tener múltiples efectos adversos agudos y crónicos. La calidad de la evidencia en este campo se ha visto limitada por la corta duración de los estudios, los reducidos tamaños de las muestras, la falta de grupos de control y la existencia de sesgos en la mayoría de los estudios revisados. En este contexto, son necesarios más estudios de mejor calidad metodológica para apoyar el uso seguro de esta terapia en otras enfermedades. La decisión de incorporar los cannabinoides como terapia en alguna de las condiciones descritas depende de la evidencia, el uso de terapias previas y el tipo de paciente.

Since ancient times cannabis has been used for recreational and medicinal purposes. It is a significant source of chemical compounds, most of them called phytocannabinoids. These compounds have several physiological effects and produce their effects primarily by binding to endogenous cannabinoid receptors such as CB1 and CB2, among others. Cannabis has potential therapeutic properties and its preparations have been used as traditional remedies to treat pain and emesis. Synthetic cannabinoids are used clinically as analgesics, antispastics, antiemetics, and appetite stimulants. Significant cannabis toxicity is rare in adults; however, it can produce countless acute and chronic side effects. The quality of the evidence in this field is limited by the short duration of the trials, poor sample sizes, lack of a control group, and the existence of bias in most of the reviewed studies. Therefore, a larger number of studies with better methodological quality is required to support the safe use of this therapy. The decision to include cannabinoids as a treatment for any of the conditions described will depend on the evidence, the use of previous therapies, and the type of patient.

El marcapasos es un dispositivo que se utiliza como medida de tratamiento de ciertos tipos de arritmias, mejorando así la calidad de vida de las personas que padecen de esta afección de salud. A nivel nacional no se disponen de estudios en relación a esta temática por lo que el objetivo fue Determinar las principales indicaciones y complicaciones del implante de marcapasos endocárdico percutáneo definitivo en paciente del Hospital Militar Central De El Salvador en el periodo de 2018 a diciembre de 2021, la metodología fue fundamentada en el tipo de estudio descriptivo, documental, de corte transversal la población en estudio fueron 16 pacientes con colocación de implante de marcapasos durante el tiempo del estudio, se utilizó la técnicas de revisión de expedientes auxiliándose de la ficha de revisión de expediente clínicos. Resultado que el 87.5% son mayores de 70 años, el 62.5% fueron más mujeres que hombres, el 56.25% fue por la enfermedad del nodo, no se presentaron complicaciones, por lo que la conclusiones fueron que la mayoría de marcapasos implantados son marcapasos bicameral, por indicación de enfermedad del nodo, sin complicaciones y con una instancia en su mayoría de 1 a 2 días, Por lo que la investigación certifica que el avance de la edad condiciona a la colocación de marcapasos, al igual que el sexo que son factores que se relacionan a la susceptibilidad, como lo es la enfermedad de coronaria como lo es la enfermedad del nodo y bloqueo AV de 2° y 3° grado.

The pacemaker is a device that is used as a treatment measure for certain types of arrhythmias, thus improving the quality of life of people who suffer from this health condition. At the national level, there are no studies in relation to this topic, therefore that the objective was to know the main indications and complications of the definitive percutaneous endocardial pacemaker implantation in a patient at the Central Military Hospital of El Salvador in the period from 2018 to December 2021, the methodology was based on the type of descriptive, documentary, cross-sectional and retrospective, with a study population of 16 patients with pacemaker implant placement during the study time, file review techniques were used with the help of the clinical file review sheet, resulting in 87.5% are older than 70 years, 62.5% were more women than men, 56.25% were due to node disease, it was not presented complications, so the conclusions were that the majority of implanted pacemakers are dual-chamber pacemakers, due to indication of node disease, without complications and with an instance mostly of 1 to 2 days. Therefore, the investigation certifies that the progress Age determines the placement of pacemakers, as well as sex, which are factors related to susceptibility, such as coronary artery disease, 2nd and 3rd degree AV block and nodal disease.

Utilización y farmacovigilancia de inmunoglobulina G endovenosa en un hospital pediátrico de alta complejidad / Intravenous immunoglobulin G use and pharmacovigilance in a tertiary care children's hospital

Introducción. La inmunoglobulina G endovenosa (IGEV) es un medicamento hemoderivado de inmunoglobulina G polivalente y policlonal. Posee un amplio espectro de indicaciones como inmunomodulador o como terapia de reemplazo. Asimismo, si bien se considera un tratamiento seguro, la incidencia de reacciones adversas reportadas en la literatura varía del 1 % al 81 %. Este trabajo tuvo como objetivo evaluar la utilización de IGEV y describir los acontecimientos adversos por la medicación en un hospital pediátrico de alta complejidad.Población y métodos. Se realizó un estudio de farmacoepidemiología, observacional y prospectivo. Se evaluaron pacientes que recibieron IGEV durante 7 meses, en 6 áreas de un hospital pediátrico de alta complejidad de la Ciudad Autónoma de Buenos Aires. La unidad de análisis fue cada infusión de IGEV, y la principal variable de estudio fue la presencia de reacciones adversas.Resultados. Se analizaron 305 infusiones en 111 pacientes. El 81,6 % de las indicaciones fueron de tipo supletorio. La dosis máxima utilizada fue 1 g/kg. En el 99,6 % de las infusiones, se indicó algún tipo de premedicación; la difenhidramina fue la droga más utilizada, aunque con diferentes posologías. Se registraron 12 reacciones adversas (el 3,9 % de las infusiones), tres de las cuales se consideraron graves: dos meningitis asépticas y una crisis comicial. Todas se resolvieron ad integrum.Conclusiones. La tasa de reacciones adversas de la IGEV en nuestro medio fue baja, con mayoría de reacciones leves e inmediatas y evolución favorable en todos los pacientes.

Introduction. Intravenous immunoglobulin G (IVIG) is a blood product from polyvalent and polyclonal immunoglobulin G. It covers a broad range of indications as immunomodulator or replacement therapy. In addition, although it is considered a safe therapy, the incidence of adverse reactions reported in the bibliography ranges from 1 % to 81 %. The objective of this study was to assess IVIG use and describe related adverse events in a tertiary care children's hospital.Population and methods. This was a pharmacoepidemiological, observational, and prospective study. Patients receiving IVIG for 7 months in 6 areas of a tertiary care children's hospital in the Autonomous City of Buenos Aires were assessed. The analysis unit was each IVIG infusion, and the main variable was the presence of adverse reactions.Results. A total of 305 infusions in 111 patients were analyzed. In 81.6 % of cases, the indication was for replacement. The maximum dose was 1 g/kg. In 99.6 % of infusions, some type of premedication was indicated; diphenhydramine was the most common drug, with varying dosages. A total of 12 adverse reactions (3.9 % of infusions) were recorded; 3 were severe: aseptic meningitis (2 cases) and seizures (1 case). All resolved to normal.Conclusions. The rate of IVIG adverse reactions in our setting was low; most reactions were mild and immediate and resolved favorably in all patients

Cnidoscolus aconitifolius: therapeutic use and phytochemical properties. Literature review / Cnidoscolus aconitifolius: usos terapéuticos y propiedades fitoquímicas. Revisión de la literatura

Abstract Introduction: Medicinal plants have been traditionally used to cure or alleviate infectious and non-infectious diseases. They are widely accepted due to their low cost and low toxicity indexes. These plants are frequently used in cases involving skin irritation, superficial wounds, insect bites, and snake bites. Objective: To compile available evidence on the main therapeutic uses and phytochemical components of Cnidoscolus aconitifolius (popularly known as chaya), a plant that grows in tropical regions of Mexico and Central America. Materials and methods: A literature review of studies on C. aconitifolius published until 2017 was conducted in the BIREME, PubMed/Medline, Elsevier and SciELO databases. Descriptors "Cnidoscolus" and "aconitifolius" were used for the literature search, and no language restrictions were applied. Results: 82 articles were retrieved after completing the initial search. Once the studies were filtered by title (descriptors in the title) and duplicates were removed, 18 articles were reviewed. Based on the information found, it was possible to confirm that this plant has multiple health benefits. Conclusions: The traditional therapeutic use of Cnidoscolus aconitifolius is backed by scientific evidence. Therefore, further research aimed at identifying new phytochemical properties of this plant should be conducted to establish alternative therapies for treating different conditions.

[Use (and abuse) of antibiotics in perinatal medicine]. / Uso (y abuso) de antibióticos en la medicina perinatal.

INTRODUCTION: The rational use of antibiotics (ATB) implies that patients receive those adequate for their clinical needs, in correct doses according to their individual conditions, during an adequate period of time, and at the lowest cost for them and their community. The highest rate of ATB abuse occurs during the perinatal period, despite the fact that there is evidence of multiple short- and long-term negative effects. Furthermore, this abuse is associated with increased costs of medical care. OBJECTIVE: To update and report the evidence on the use, abuse, and adverse effects of ATB in perinatal medicine, and possible measures to prevent them, and thus improve health care outcomes and costs. METHODS: A review and analysis was performed from the literature related to the use of ATB in perinatal medicine up to February 2020. RESULTS: ATB abuse in perinatal medicine ranges from 50% to 70%, with even higher rates in some neonatal centres. Adverse effects include death, increased microbial resistance, along with microbiome abnormalities and dysbiosis that lead to serious life-long complications such as infections, allergies, autoimmune disorders, gastrointestinal disorders, arthritis, asthma, obesity, and perhaps cancer. Preventing and reducing the abuse of ATB would lead to better health and to significant savings in the health sector. In only 4neonatal intensive care units, with 1000 admissions per year, savings are estimated at US$230,000 per year. CONCLUSION: The need to optimise the use of ATB in perinatal medicine has never been more urgent.

Prescripción e indicaciones de uso de fluoroquinolonas en un grupo de pacientes ambulatorios de Colombia / Prescription and indications for the use of fluoroquinolones in a group of outpatients in Colombia

Introducción. Existen evidencias sobre el uso indiscriminado de antibióticos en el tratamiento de diversas enfermedades. Objetivo. Determinar los patrones de prescripción y de indicaciones de uso de las fluoroquinolonas en un grupo de pacientes ambulatorios en Colombia. Materiales y métodos. Se llevó a cabo un estudio descriptivo farmacoepidemiológico del tipo de prescripción e indicaciones de uso a partir de una base de datos poblacionales que incluía pacientes con prescripciones ambulatorias de fluoroquinolonas entre mayo y octubre de 2018. Se recabó la información sobre las variables sociodemográficas, farmacológicas y clínicas (diagnóstico según la Clasificación Internacional de Enfermedades, versión 10) y se estableció la proporción del uso de fluoroquinolonas en indicaciones aprobadas y no aprobadas por las agencias reguladoras. Resultados. Se identificaron 23.373 pacientes que habían recibido fluoroquinolonas; su edad media era de 47,9 ± 18,1 años y 15.767 eran mujeres (67,5 %). La ciprofloxacina fue el medicamento más prescrito (n=19.328; 82,7 %), seguida de la norfloxacina (n=3.076; 13,2 %), la levofloxacina (n=573; 2,5 %) y la moxifloxacina (n=394; 1,7 %). Las principales indicaciones fueron la infección de las vías urinarias en sitio no especificado (n=10.777; 46,1 %), la diarrea y la gastroenteritis de presunto origen infeccioso (n=3.077, 13,2 %) y la cistitis aguda (n=956; 4,2 %). El 76 % (n=17.759) de las prescripciones correspondía a indicaciones aprobadas y el resto a usos no aprobados, como la rinofaringits o las infecciones de tejidos blandos. El ser hombre (odds ratio, OR=1,26; IC95%: 1,18-1,34) y tener menos de 35 años (OR=1,92; IC95%:1,48-1,50) se asociaron con una mayor probabilidad de uso de fluoroquinolonas en indicaciones no aprobadas. Conclusión. Las fluoroquinolonas, en particular la ciprofloxacina, se están prescribiendo especialmente a mujeres con infecciones de las vías urinarias, pero hasta la cuarta parte de los pacientes las recibieron para usos no aprobados por las agencias reguladoras.

Introduction: There is evidence of the indiscriminate use of antibiotics for different pathologies. Objective: To determine the prescription patterns and indications for the use of fluoroquinolones in a group of outpatients in Colombia. Materials and methods: We conducted a descriptive pharmaco-epidemiological study on prescription-indication using a population database where patients with outpatient fluoroquinolone prescriptions were included from May to October, 2018. We obtained the information on sociodemographic, pharmacological, and clinical variables, as well as on the diagnosis according to the International Classification of Diseases, version 10, and we established if the use was approved by the regulatory agencies or if it was off-label. Results: A total of 23,373 patients were identified who were using fluoroquinolones; their mean age was 47.9 ± 18.1 years and women predominated (n=15,767, 67.5%). Ciprofloxacin was the medication most commonly prescribed (n=19,328, 82.7%), followed by norfloxacin (n=3076, 13.2%), levofloxacin (n=573, 2.5%), and moxifloxacin (n=394; 1.7%). The main indications were urinary tract infection in unspecified site (n=10,777, 46.1%), diarrhea and gastroenteritis of presumed infectious origin (n=3077, 13.2%), and acute cystitis (n=956; 4.2%). The prescriptions followed approved indications in 76% (n=17,759) of cases while the rest were used off-label or without indication for nasopharyngitis or soft-tissue infections, for example. Being male (OR=1.26, 95%CI:1.18-1.34) and under 35 years of age (OR=1.92, 95%CI:1.48-1.50) were associated with a greater probability of using fluoroquinolones in unapproved indications. Conclusions: Fluoroquinolones, particularly ciprofloxacin, are being prescribed especially to women with urinary tract infections, but up to a quarter of the patients received them for unapproved indications by regulatory agencies.

25 años de CENTIS. Pandemia y Radiofármacos / 25 years of CENTIS. Pandemic and Radiopharmaceuticals

Resumen Próximo a su 25 aniversario CENTIS reflexiona sobre su quehacer en el contexto de los trastornos que causa la COVID-19. Con ese propósito se examinan el estado de la medicina nuclear y la radiofarmacia antes y durante la epidemia y sus perspectivas de desarrollo. La producción global de radiofármacos continúa siendo una industria consolidada y aunque la pandemia afecta a esta esfera, la presencia de otras enfermedades no cesa, por lo que los servicios de medicina nuclear esenciales y críticos siguen siendo necesarios. Se espera su paulatina reapertura y que se retome con más fuerza la investigación, dado que la COVID-19 es tan compleja y se asocia a tantos factores que constituye, en perspectiva, terreno virgen para las técnicas diagnósticas en medicina nuclear. Ha de permanecer asimismo el papel de los radiofármacos terapéuticos en un grupo importante de enfermedades, en cáncer sobre todo. El Centro de Isótopos pone por ello énfasis tanto en la consolidación, bajo buenas prácticas, de la producción y el suministro de radiofármacos, como en el desarrollo de nuevos productos. Ambos aspectos se basan principalmente en dos radionúclidos: Tc-99m e Y-90.

Abstract Close to its 25th anniversary, CENTIS evaluates its work in the context of the disorders triggered by COVID-19. For this purpose, the situation of nuclear medicine and radiopharmacy, before and during the epidemic and their current development prospects is examined. The production of radiopharmaceuticals continues to be a consolidated global industry and although the pandemic affects this area, the presence of other diseases does not cease, so essential and critical nuclear medicine services are still needed, therefore its gradual reopening is expected. In addition, research will be taken with more strength, given that COVID-19 is so complex and associated with so many factors that it constitutes virgin terrain in perspective for diagnostic techniques in nuclear medicine. The role of therapeutic radiopharmaceuticals in an important set of diseases, especially cancer, will also remain. As a result, the Isotope Center focus its attention under good management practices, on the consolidation of the production and distribution of radiopharmaceuticals and in the development of new products. Both aspects are mainly based on two radionuclides: Tc-99m and Y-90.

Cannabis medicinal: riesgos relacionados con la indicación previa a su aprobación / Medical cannabis: Risks related to its indication prior to approval

En los últimos años, se ha observado un incremento significativo en el interés por la prescripción del cannabis medicinal. En el siguiente artículo, se informa acerca de la escasa base científica que avala la prescripción de estos compuestos en un listado amplio y diverso de patologías médicas. Se considera fundamental que cualquier sustancia que vaya a ser utilizada en humanos siga un protocolo de aprobación estricto y científico, que pueda desligarse de modas o de resultados individuales. Es necesario que, antes de la prescripción de una droga en personas, deba tenerse un panorama claro de cuáles son los usos del compuesto en cuestión, pero, sobre todo, de su seguridad, que es prácticamente desconocida en el cannabis medicinal.

In recent years, the interest in medical cannabis prescription has increased significantly. This article provides information about the little scientific basis supporting the prescription of these products for a wide and diverse range of medical conditions. It is critical for any substance to be used in human beings to follow a strict scientific approval protocol, detached from any trend or individual outcome. Before prescribing any drug to human beings, it is necessary to have a clear picture of its uses, especially its safety, which is practically unknown in the case of medical cannabis.

Proton pump inhibitor indications in a Brazilian tertiary hospital

SUMMARY OBJECTIVES To evaluate the frequency of prescription of proton pump inhibitors (PPIs) and their indications in patients hospitalized at the Hospital de Clínicas of the Federal University of Uberlândia (HC-UFU). METHODS This is a quantitative cross-sectional observational study that analyzes data obtained from patient records on prescriptions of PPIs for patients hospitalized at the HC-UFU and from a questionnaire applied to assistant physicians on the indications of the drug in each case and evaluates the indication based on literature data. RESULTS On a pre-determined day, of a total of 462 inpatients, there was a prescription of PPI for 183 (39.3%), with a higher frequency (73.5%) in the Intensive Care Unit (ICU), followed by the infirmaries and the Emergency Room. The assistant physician was located in 116 cases, and the main motivation referred to prescription was prophylaxis of digestive hemorrhage (77%). However, after reviewing medical records, it was noticed that in 50.8% of the cases, the prescription was not supported by the literature. CONCLUSION The frequency of PPI prescriptions for inpatients in the HC-UFU is among the lowest described in the literature, but there are still unnecessary prescriptions. Instruction and awareness of the assisting team can minimize these numbers.

RESUMO OBJETIVOS Avaliar a frequência da prescrição de inibidores da bomba de prótons (IBPs) e suas indicações em pacientes internados no Hospital de Clínicas da Universidade Federal de Uberlândia (HC-UFU). MÉTODOS Estudo observacional transversal quantitativo, análise de dados obtidos em prontuários sobre prescrições de IBPs para pacientes internados no HC-UFU, aplicação de questionário aos médicos assistentes sobre as indicações do medicamento em cada caso e avaliação dessas indicações com base em dados da literatura. RESULTADOS Em um dia predeterminado, de 462 pacientes internados, houve prescrição de IBP para 183 (39,3%), com maior frequência (73,5%) em Unidade de Terapia Intensiva (UTI), seguida das enfermarias e do pronto-socorro (PS). O médico assistente foi localizado em 116 casos, a principal motivação referida para prescrição foi a profilaxia de hemorragia digestiva (77%). Entretanto, após revisão de prontuários, percebeu-se que em 50,8% a prescrição não era respaldada por literatura. CONCLUSÃO A frequência de prescrição de IBP para pacientes internados no HC-UFU está entre as menores descritas na literatura, mas ainda há prescrições desnecessárias. Orientação e conscientização da equipe assistente podem minimizar esses números.

Impacts of cytochrome P450 2D6 (CYP2D6) genetic polymorphism in tamoxifen therapy for breast cancer impactos do polimorfismo genético do citocromo P450 2D6 (CYP2D6) na terapia com tamoxifeno para câncer de mama

Abstract Tamoxifen (TMX) is the main drug used both in pre and postmenopausal women as adjuvant treatment for hormone receptor-positive breast cancer. An important barrier to the use of TMXis the development ofdrug resistance causedby molecular processes related to genetic and epigenetic mechanisms, such as the actions of cytochrome P450 2D6 (CYP2D6) polymorphisms and of its metabolites. The present study aimed to review recent findings related to the impact of CYP2D6 polymorphisms and how they can affect the results of TMX in breast cancer treatment. The keywords CYP2D6, tamoxifen, and breast cancer were searched in the PubMed, Scopus, The Cochrane Library, Scielo, and Bireme databases. Studies related to other types of neoplasms or based on other isoenzymes from cytochrome P450, but not on CYP2D6, were excluded. The impact of CYP2D6 polymorphisms in the TMX resistance mechanism remains unclear. The CYP2D6 gene seems to contribute to decreasing the efficacy of TMX, while the main mechanism responsible for therapy failure, morbidity, and mortality is the progression of the disease.

Resumo Otamoxifeno é a principal drogaque pode ser utilizada comotratamentohormonal adjuvante empacientesportadoras de câncer demamareceptor hormonal positivotanto na pré- quanto na pós-menopausa.Umadasmaiores barreirasemseu uso é o desenvolvimento de resistência medicamentosa causada por meio de processos moleculares relacionados a mecanismos genéticos e epigenéticos, como a ação dos polimorfismos do gene citocromo P450 2D6 (CYP2D6) e seus metabólitos.Opresente estudo busca revisar as descobertas recentes acerca dos impactos dos polimorfismos do gene CYP2D6 e de como eles podem afetar os resultados do tamoxifeno na terapêutica do câncer de mama. As palavras-chave CYP2D6, tamoxifeno e câncer de mama foram buscadas nas bases de dados Pubmed, Scopus, The Cochrane Library, Scielo e Bireme. Estudos relacionados com outros tipos de câncer ou relacionados a outras isoenzimas do citocromo P450 que não o CYP2D6 foram excluídos. O impacto do polimorfismo do CYP2D6 nos mecanismos de resistência ao tamoxifeno permanecem controversos. O gene CYP2D6 parece reduzir a eficácia do TMX; entretanto, os principais fatores associados a falha terapêutica são morbimortalidade e a progressão da doença

Indicaciones de cesárea / Indications of Cesarea

Objetivo: Aportar a la calidad de atención y seguridad del paciente, mediante la correcta indicación de operación cesárea, basada en la mejor evidencia científica disponible, definiendo criterios de indicación de esta intervención quirúrgica. Materiales y métodos: Se realiza una estrategia de búsqueda para el desarrollo de la revisión de artículo, donde se revisa sitios web como; aNational Guideline Clearinghouse (NGC), Hinari, PubMed. Se valoran la Guía Nacional de práctica clínica: Guías de práctica clínica y de procedimientos en obstetricia y perinatología. Minist Salud Perú INMP. Conclusiones: La cesárea es el procedimiento quirúrgico más realizado en el mundo en mujeres en edad reproductiva, es motivo de preocupación en salud pública que su indicación sea la correcta, evitando consecuencias en morbilidad y mortalidad que pudiesen resultar de su sobre indicación. Reportándose elevadas tasas de prevalencia de realización de cesáreas en países en vías de desarrollo como nuestro país que supera las tasas indicadas por la OMS que recomiendan un total de 15% del total de nacimientos. Su real posicionamiento en la práctica obstétrica se comprenderá una vez se entiendan las reales ventajas y desventajas de su ejecución, no sólo en lo referente al embarazo en curso sino respecto de la historia reproductiva final de la paciente. Por ello se hace necesario que los criterios, sean precisos para la indicación de una cesárea, realizar protocolos, unificar conocimientos y actitudes hacia la cesárea, y que no sea un procedimiento habitual. (AU)

Objective: : To contribute to the quality of care and patient safety, by means of the correct indication of cesarean section, based on the best available scientific evidence, defining criteria for the indication of this surgical intervention. Materials and methods: A search strategy is developed for the development of the article review, where websites such as; aNational Guideline Clearinghouse (NGC), Hinari, PubMed. The National Guide of clinical practice is valued: Clinical practice guides and procedures in obstetrics and perinatology. Minist Salud Perú INMP.Conclusions: Caesarean section is the most performed surgical procedure in the world in women of reproductive age, it is a cause of concern in public health that its indication is correct, avoiding consequences in morbidity and mortality that could result from its over indication. There are high prevalence rates of cesarean sections in developing countries, such as our country that exceeds the rates indicated by the WHO, which recommend a total of 15% of all births. Its real positioning in obstetric practice will be understood once the real advantages and disadvantages of its execution are understood, not only in relation to the current pregnancy but also in relation to the final reproductive history of the patient.For this reason, it is necessary that the criteria are precise for the indication of a cesarean section, to carry out protocols, to unify knowledge and attitudes towards cesarean section, and that it is not a usual procedure.
