RESUMO
Although the most important primary local inflammatory response factor to intubation is not yet clear, it is known that it may be directly attributed to the presence of trauma during intubation or the response of oral bacterial flora present in the trachea. It is known that prolonged intubation is associated with worse outcomes, but other underlying systemic issues, such as sepsis and trauma, are also associated with this result. Likewise, patients who require advanced airway management and excessive manipulation are more likely to experience complications. There are various inflammatory mediators that are generated during orotracheal intubation, many of which can be considered targets for therapies to help reduce inflammation caused by intubation. However, there is little evidence on the management of the inflammatory response induced by orotracheal intubation in pediatric patients. Therefore, the aim of this narrative review is to highlight the intubation associated complications that can arise from poorly controlled inflammation in intubated pediatric patients, review the proposed pathophysiology behind this, and discuss the current treatments that exist. Finally, taking into account the discussion on pathophysiology, we describe the current therapies being developed and future directions that can be taken in order to create more treatment options within this patient population.

Inbreeding (reproduction between relatives) often decreases the fitness of offspring and is thus expected to lead to the evolution of inbreeding avoidance strategies. Chimpanzees (Pan troglodytes) are expected to avoid inbreeding as they are long-lived, invest heavily in offspring and may encounter adult, opposite sex kin frequently, especially in populations where both males and females commonly remain in the group in which they were born (bisexual philopatry). However, it is unclear whether substantial bisexual philopatry has been a feature of chimpanzees' evolutionary history or whether it is a result of recent anthropogenic interference, as the only groups for which it has been documented are significantly impacted by human encroachment and experience notable rates of potentially unsustainable inbreeding. Here we use 14 years of observational data and a large genomic dataset of 256 481 loci sequenced from 459 individuals to document dispersal and inbreeding dynamics in an eastern chimpanzee (P. t. schweinfurthii) community with low levels of anthropogenic disturbance. We document the first case of substantial bisexual philopatry in a relatively undisturbed chimpanzee community and show that, despite an increased inbreeding risk incurred by females who do not disperse before reaching reproductive age, natal females were still able to avoid producing inbred offspring.
RESUMO
Post-herpetic neuralgia (PHN) is an entity derived from peripheral nerve damage that occurs during the reactivation of the Varicella Zoster Virus (VZV), which manifests itself through pain with neuropathic characteristics. This can prove to be very difficult to manage in the chronic stages of disease reappearance. There currently exists a multitude of treatment alternatives for PHN, however, prevention through the early initiation of antiviral regimens is vital. There are various pharmacological options available, but it is important to individualize each patient to maximize efficacy and minimize adverse effects. Interventional procedures have become a cornerstone in difficult-to-manage cases, and have shown promising outcomes when used in a multimodal approach by experienced specialists. It is necessary to make an objective diagnosis of PHN and start early treatment. Additionally there is current evidence that vouches for interventional therapies as well as individualization, with a clear establishment of therapeutic objectives according to the needs of each patient.

Isopropyl alcohol (IA) is a colorless, flammable organic compound that has been used in the manufacturing process of a wide variety of industrial and household chemicals. Inhalation of its vapor has been noted to potentially have antiemetic effects, which may be useful in the treatment of postoperative nausea and vomiting (PONV). However, given the varied study protocols and endpoints assessing its efficacy as antiemetic, clinical trials have yielded mixed results. If effective, inhalation of IA may be a cost-effective, readily available, and inexpensive therapy that can be used for the treatment of PONV with a low risk of adverse effects. The following narrative review explores the available information regarding the mechanism of action of IA in treating PONV, presents clinical information including possible mechanism of action and clinical applications, and reviews the published literature on its efficacy to treat nausea and vomiting with a focus on its use postoperatively. While early studies suggested that inhaled IA may be successful for the short-term treatment of PONV compared with placebo, subsequent studies both in and out of the operating room (OR) have reported conflicting results. In general, studies in the perioperative setting have provided some evidence to support the use of inhaled IA in alleviating or reducing the severity of PONV in adults. In particular, inhaled IA may have a more rapid onset compared with traditional antiemetic agents, but the clinical effect has generally been found to be short-lived. The results outside of the OR and perioperative setting have been somewhat more favorable, generally showing that inhaled IA reduces nausea and vomiting of various etiologies in adults in the emergency department setting. Similarly, it has been shown to reduce the need for rescue antiemetic agents in this area and thus may be considered a cost-cutting strategy with no reported adverse effects. The available literature suggests that inhaled IA may be considered a potential therapy to achieve rapid relief of PONV and assist in the management of nausea and vomiting in adult patients outside of the perioperative setting. There remain insufficient data to determine how inhaled IA may impact PONV in children. Given the mixed results and the limitations of the current studies, additional data are needed to draw firm conclusions regarding the utility of inhaled IA.
RESUMO
BACKGROUND: Cardiovascular effects for drugs such as hyoscine butylbromide are poorly documented in the literature, unlike atropine, which is considered the antimuscarinic of choice in the presence of intraoperative bradycardia. AIM: The aim of the study was to describe the dose-related cardiovascular effect of hyoscine butylbromide in patients between 18 and 65 years of age, with low perioperative risk undergoing elective surgery under general anaesthesia on an outpatient basis or hospitalised at our institution between 1 January and 31 May 2019. METHODS: Descriptive, cross-sectional, retrospective study; 28 patients with low perioperative risk who underwent general anaesthesia were selected. Changes in heart rate and blood pressure were analysed during the first 6 minutes after the administration of hyoscine butylbromide. The data obtained was recorded in a Microsoft Excel database and analysed using the Excel analysis tool and IBM SPSS. RESULTS: The average dose of 0.15mg/kg of hyoscine butylbromide achieved an increase in heart rate and mean arterial pressure in 96% and 92.8%, respectively, in the first 6 minutes after the administration. Significant changes in heart rate and blood pressure were obtained during the first 6 minutes at doses between 0.05mg/kg and 0.15mg/kg. CONCLUSION: Hyoscine butylbromide generates positive effects on the heart rate and blood pressure of patients under general anaesthesia, representing a possible alternative in the management of intraoperative bradycardia.

Sugammadex is a medication that may have cost considerations with the potential for waste of unused product in pediatric patients due to the vial size and its single-use limitation. Therefore, exploring the potential of vial-splitting for perioperative use may be beneficial. Methods: The study was a retrospective, quality improvement study using the electronic medical record to identify every sugammadex administration over the last five years in a tertiary care pediatric institution. We divided patients into groups depending on the dose of sugammadex administered. The cost of sugammadex was calculated under three scenarios: (1) only 200-mg vials available; (2) 100-mg aliquots available; and (3) 50-mg aliquots. We then calculated the total money spent per patient in the 3 scenarios. Results: 31,063 patients received sugammadex over the study period, of whom 23.6% received 151-200 mg. The greatest percentage of patients received ≤50 mg (32.9%). The average cost per patient was $113.58, $81.61, and $68.83 if 200 mg, 100 mg, and 50 mg doses were available, respectively. Over the last 5 years, $1,390,110.13 could have been saved by having 50 and 100 mg aliquots available. Conclusions: Pediatric patients generally receive lower doses of sugammadex due to weight-based dosing, leading to increased waste and cost when using only 200-mg vials. Vial-splitting into smaller aliquots can significantly cut costs for healthcare centers and patients while decreasing waste.
RESUMO
OBJECTIVE: Painful Phantom Limb Syndrome (PPLS) occurs in 50 to 80% of patients undergoing amputation, having a great impact on quality of life, productivity and psychosocial sphere. The objective of this review is to summarize the pharmacological and non-pharmacological strategies, surgical optimization, and provide a multidisciplinary approach aimed at reducing the incidence of chronic pain associated with PPLS in patients undergoing limb amputation. METHODS: A narrative review was carried out using Medline, Pubmed, Proquest, LILACS and Cochrane, searching for articles between 2000 and 2021. Articles describing the epidemiology, pathophysiological considerations, and current treatments were selected after a screening process. RESULTS: A multidisciplinary and multimodal approach is required in PPLS, and should include the use of regional techniques, and adjuvants such as NSAIDs, ketamine, lidocaine and gabapentinoids. In addition, an evaluation and continuous management of risk factors for chronic pain in conjunction with the surgical team is necessary. CONCLUSION: The current literature does not support that a single technique is effective inthe prevention of PPLS. However, adequate acute pain control, rehabilitation and early restoration of the body scheme under a multidisciplinary and multimodal approach have shown benefit in the acute setting.

Rheumatoid Arthritis (RA) is a systemic autoimmune disease characterized by chronic inflammation and progressive deterioration of the joints, which generates pain and stiffness. The origin of this pain is multifactorial, with inflammation, secondary osteoarthritis, as well as central and peripheral sensitization playing important roles in the development. Up to 90.4% of RA patients visit a health professional for severe pain, and despite new therapies and sophisticated treatments, there are a limited number of options for analgesic management. We conducted a narrative review using the Medline and Pubmed search engines for articles in English and Spanish between 2000 and 2021, with the keywords "pain," "rheumatoid arthritis," "non-steroidal anti-inflammatory drugs" (NSAIDs), "opioids," "glucocorticoids," "disease modifying antirheumatic drugs" (DMARDs), "neuromodulators," "antidepressants," and "cannabinoids." The articles describing epidemiology, pathophysiological considerations and current treatments were selected after a screening process carried out by the authors. It was found that DMARDs are the fundamental basis of treatment, since the main mechanism of pain in this entity is inflammation. Nonetheless, a significant number of patients continue to have pain despite optimal treatment. The available evidence for pain management in RA is scarce, however, medications such as NSAIDs, topical capsaicin, weak opioids, and treatments such as joint infiltrations or surgical management, play an important role in its management. We believe more research efforts are needed to optimize analgesic treatment recommendations, however, based on the current existing evidence, we propose a stepwise algorithm in order to properly approach these cases.Key PointsRA is a systemic autoimmune disease characterized by chronic inflammation, in which the main symptom is pain.Pain in RA is multifactorial, with inflammation, secondary osteoarthritis, as well as central and peripheral sensitization playing determining roles.DMARDs are the mainstay of RA treatment, although many patients continue to experience pain despite optimal management.Medications such as glucocorticoids, NSAIDs, topical capsaicin, and weak opioids are key elements when achieving analgesia in RA.Other pharmacological groups such as neuromodulators, antidepressants, muscle relaxants and cannabinoids currently do not have enough evidence to be recommended.

Abstract Introduction: The practice of anesthesiology during the COVlD-i9/SARS-CoV-2 pandemic has had a psychological impact, and has been associated with ethical dilemmas, work overload, and occupational risk. Objective: To understand different problems affecting anesthesiologists, in particular with regards to professional ethics in the decision-making process, increased personal workload, and the potential risk in terms of their own safety and health, as a consequence of working during the COVlD-19 pandemic. Methods: Observational, descriptive, cross-sectional study. A survey was administered to anesthesiologists members of the Colombian Society of Anesthesiology and Resuscitation (S.C.A.R.E.), to enquire about work hours, occupational safety, prevention standards and strategies, and ethical aspects involved in decision making during the COVID-19 pandemic. Results: 218 anesthesiologist participated in the survey. Most of the respondents felt that there was not a significant increase in their workload, except for those in critical care (42.5 %; n = 17). Most of the participants believe that leisure time is not enough. 55.96 % (n = 122) of the participants said they felt moderately safe with the biosecurity measures, but with a higher risk of contagion versus other practitioners, with 72.9 % (n = 159) responding that they used their own money to buy personal protection equipment (PPE). There was also evidence that one fourth of the respondents has faced ethical dilemmas during the resuscitation of SARS-CoV-2 - infected patients. Conclusions: The information gathered is a preliminary approach to the situation arising in Colombia as a result of the pandemic; it is clear that anesthesiologists perceive higher associated lack of safety due to different factors such as higher risk of infection, shortage of PPEs and burnout, inter alia. Hence we believe that it is fundamental to acknowledge the work of all anesthesiologists and understand the impact that the pandemic has had on this group of professionals.
Resumen Introducción: El ejercicio de la anestesiología durante la pandemia por COVID-i9/SARS-CoV-2 ha tenido un impacto psicológico y ha estado asociado a dilemas éticos, aumento en la sobrecarga y riesgo laboral. Objetivo: Comprender distintos problemas en los que se han visto envueltos los médicos anestesiólogos, en especial los relacionados con su ética profesional en el proceso de tomar decisiones, el aumento en la carga personal y el posible riesgo de su seguridad y salud como consecuencia de su labor durante la pandemia por COVID-19. Métodos: Estudio observacional, descriptivo, de corte transversal. Por medio de una encuesta, aplicada a anestesiólogos afiliados a la Sociedad Colombiana de Anestesiología y Reanimación (S.C.A.R.E.), se indagó acerca de jornadas laborales, seguridad laboral, normas y estrategias de prevención, y aspectos éticos vinculados con la toma de decisiones durante la pandemia por COVID-19. Resultados: Participaron 218 anestesiólogos. La mayoría de los encuestados consideró que no hubo aumento significativo en su carga laboral, excepto aquellos que ejercen en cuidado crítico (42,5 %; n = 17). La mayoría de los participantes consideran que el tiempo de descanso no es suficiente. Un 55,96 % (n = 122) de los participantes, refieren sentirse moderadamente seguros con las medidas de bioseguridad, pero con un mayor riesgo de contagio frente a otros profesionales, con un 72,9 % (n = 159) y manifestaron haber invertido de sus propios recursos para la adquisición de elementos de protección personal (EPP). Así mismo, se evidenció que una cuarta parte de los entrevistados se ha enfrentado a dilemas éticos durante la reanimación de pacientes infectados por SARS-CoV-2. Conclusiones: La información obtenida hace un acercamiento inicial a la problemática generada en Colombia por la pandemia, donde es evidente que los anestesiólogos perciben una mayor inseguridad asociada, debido a diversos factores como mayor riesgo de infección, insuficiencia de EPP y burnout, entre otros. Por ende, creemos que es fundamental reconocer el trabajo de todos los anestesiólogos, y comprender el impacto que la pandemia ha tenido en estos profesionales.
