ABSTRACT

Abstract BACKGROUND: Primary hyperhidrosis is a condition characterized by excessive sweating, inconsistent with the needs for thermoregulation. OBJECTIVE: To assess the effectiveness and the change in the quality of life of patients undergoing bilateral VATS (video-assisted thoracoscopic sympathectomy) for treatment of hyperhidrosis, in a large case series. DESIGN AND SETTING: Cohort study conducted in a tertiary hospital specializing in hyperhidrosis located in São Paulo, Brazil. METHODS: A total of 2,431 patients who underwent surgery consisting of bilateral video-assisted thoracoscopic sympathectomy between January 2000 and February 2017 were retrospectively assessed in an outpatient clinic specializing in hyperhidrosis. The patients underwent clinical and quality of life assessments on two occasions: firstly, prior to surgery, and subsequently, one month after the operation. The presence or absence of compensatory hyperhidrosis (CH) and general satisfaction after the first postoperative month were also evaluated. RESULTS: All the patients operated had poor or very poor quality of life before surgery. In the postoperative period, an improvement in the quality of life was observed in more than 90% of the patients. Only 10.7% of the patients did not present CH, and severe CH occurred in 22.1% of the patients in this sample. CONCLUSION: Bilateral VATS is a therapeutic method that decreases the degree of sweating more than 90% of patients with palmar and axillary hyperhidrosis. It improves the quality of life for more than 90% of the patients, at the expense of development of CH in approximately 90% of the patients, but not intensely.

ABSTRACT

ABSTRACT Hyperhidrosis is characterized by excessive sweating and it affects almost 5% of the population. The affected age group is wide, and it can affect from children to elderlies. There are two types of hyperhidrosis: generalized and focal. Treatment depends on the symptoms presented. In more severe cases, radiofrequency sympatholysis and bilateral thoracic sympathectomy are the options. However, recurrence is possible or the postoperative appearance of conditions called compensatory hyperhidrosis or reflex hyperhidrosis. We describe two cases of patients treated with Cannabidiol who had significant and unexpected improvement of hyperhidrosis. The first patient received Cannabidiol specific for public presentations at work, and the second patient had a diagnosis of autism spectrum disorder. The hyperhidrosis improved in both patients immediately after using Cannabidiol.

ABSTRACT

Resumen La hiperhidrosis es un trastorno caracterizado por la producción excesiva de sudor por las glándulas sudoríparas ecrinas que influye negativamente en las actividades sociales, laborales y fundamentalmente en la calidad de vida. Se divide en primaria o secundaria. La primaria es una enfermedad benigna caracterizada por una excesiva sudoración con mayor frecuencia en palmas, plantas, axilas y cara. Su incidencia es del 1% de la población y su causa es desconocida. La mayoría de los tratamientos médicos no logran un buen control sintomático y frecuentemente son transitorios. La simpaticotomía torácica bilateral videoasistida se ha vuelto el tratamiento de elección en pacientes muy sintomáticos. En el período de 1998 a 2018 se realizaron 174 simpaticotomias bilaterales videoasistidas por hiperhidrosis primaria, de las cuales 102 cumplieron los criterios de inclusión. Se excluyeron a 72 pacientes. El 20.5% fueron hombres y el 79.5% mujeres con una edad media de 29.22 años. En cuanto a la localización fue palmoplantar axilar en un 50.9%, axilar en un 23.5%, palmoplantar en un 10.7%, palmar en un 7.8%, palmoaxilar 6.8% y facial 5.8%. Los pacientes con sudoración palmar presentaron 94.9% de mejoría, axilar 84.51%, plantar 46.25% y facial 84% respectivamente. El post operatorio arrojó una media de internación de 1.1 días. Como efecto no deseado, se presentó sudoración compensatoria en 53 casos y complicaciones postoperatorias en 18 casos. Concluimos que es una técnica segura, que resuelve de manera significativa la sudoración, mejorando la calidad de vida.


Abstract Hyperhidrosis is a disorder consisting of excessive sweating through the different body sweat glands, which produces a negative impact socially and in work-related activities in those that suffer this condition. There are primary and secondary forms. The primary form is a benign condition with excessive sweating mainly in palms, soles of feet, axillae and face. It affects a 1% of the population, and its cause is unknown. Most medical treatments are unsuccessful, and at best, transitory. In patients who are very troubled by the condition, videoassisted bilateral thoracic sympathicotomy has become the elective treatment. In the period ranging from 1998 to 2018, 174 procedures were undertaken for primary hyperhidrosis, of which 102 satisfied the inclusion criteria. 72 patients were excluded. A 20.5% were males, and 79.5% were females, with an average age of 29.22 years at surgery. As to localization of sweating, a 50.9% was palmar-plantar-axillary, 23.5% axillary, 10.7% palmarplantar, 7.8% palmar, 6.8% palmar-axillary, and a 5.8% facial. Those patients with palmar sweating showed a 94.9% improvement, those with axillary sweating a 88.51%, with plantar a 46.25% and those with facial sweating a 84% improvement. The average admission time was 1.1 days. As an undesired effect, compensatory sweating occurred in 53 cases and postoperative complications in 18 cases. We conclude this is a safe technique, that diminishes sweating significantly, improving patient's quality of life.

ABSTRACT

ABSTRACT Background: The surgical treatment of hyperhidrosis by thoracic sympathectomy has brought, in addition to symptomatic relief for many, its main adverse effect: compensatory or reflex sweating. The clipping technique in place of the sympathetic nerve section gave rise to the hope of reversibility, but the positive results showed to be quite divergent, evidencing the academic deficiency regarding the study of this phenomenon. Aim: To observe micro and macroscopic damage caused by the polymer clip on sympathetic nerve of rabbits seven days after their clipping and the findings after three weeks of clip removal. Method: In this experimental study, 20 rabbits were divided into two groups of 10, group 1 (clipping) and group 2 (de-clipping). The right cervical sympathetic nerve of all animals was clamped with polymeric clip, and in group 2 the nerve was unclipped seven days later. Group 1 rabbits were induced to death on the 7th postoperative day, and group 2 on the 21st after removal of the polymer clip. Macroscopic variables were: clip appearance, presence of discontinuity lesion, infection and adhesions around the nerve. H&E was used in the evaluation of the phases and degree of the inflammatory process and presence of necrosis, and picrosirius red F3BA for quantification of collagen. Results: The cervical sympathetic nerve was intact, without necrosis or infection in all animals of the experiment; there were adhesions in both groups, being minimal in eight animals of each group and moderate or intense in two; the clip was completely closed in all animals at the 7th postoperative day; the inflammatory process shown was chronic, with monomorphonuclear predominance. There was no significant difference between groups regarding the intensity the inflammatory process, but the amount of collagen type I and type III was significantly higher in group 2. Conclusions: The injury caused by the polymer clip on the sympathetic nerve may be reversible, allowing functional return in the areas involved in the simulated cervical sympathectomy. Clipping of the cervical sympathetic nerve using a polymer clip does not cause discontinuity injury.


RESUMO Racional: O tratamento cirúrgico da hiperidrose pela simpatectomia torácica trouxe além do alívio sintomático para muitos, também seu principal efeito adverso: o suor compensatório ou reflexo. A técnica de clipagem do nervo simpático no lugar de sua secção deu margem à esperança de reversão do procedimento; porém, os resultados mostram-se bastante divergentes e pouco conclusivos Objetivo: Observar a lesão provocada pelo clipe de polímero em nervo simpático de coelhos sete dias após sua clipagem, comparando-a com os achados após três semanas da retirada do clipe. Método: Estudo experimental, com amostra formada por 20 coelhos, divididos em dois grupos de 10, sendo o grupo 1 chamado clipagem e o 2, desclipagem. Todos foram submetidos à clipagem do nervo simpático cervical direito com clipe polimérico, e no grupo 2 realizou-se a desclipagem sete dias após. Os coelhos do grupo 1 foram submetidos à eutanásia no 7º dia de pós-operatório, e os do grupo 2 no 21º dia após a remoção do clipe. Observou-se na macroscopia o aspecto do clipe, a presença de lesão de descontinuidade, infecção e aderências ao redor do nervo. Para estudo microscópico utilizou-se a coloração H&E na avaliação das fases, grau do processo inflamatório e presença de necrose, e a de picrosirius red F3BA para quantificação de colágeno. Resultados: O nervo simpático cervical foi identificado íntegro, sem necrose ou infecção em todos os animais do experimento; havia aderências em ambos os grupos, sendo mínimas em oito de cada grupo e moderadas ou intensas em dois; em toda a amostra o clipe encontrava-se completamente fechado no 7º dia de pós-operatório; o processo inflamatório presente foi do tipo crônico, com predomínio monomorfonuclear, não se observando diferença significativa em relação ao grau do processo inflamatório entre os grupos; porém, a quantidade de colágeno tanto do tipo I quanto do tipo III foi significativamente maior no grupo 2. Conclusões: A lesão provocada pelo clipe de polímero em nervo simpático pode ser reversível possibilitando o retorno funcional nas áreas envolvidas na simpatectomia cervical simulada. A clipagem do nervo simpático cervical com uso de clipe de polímero não causa lesão de descontinuidade.

ABSTRACT

Surgical neuromodulation therapies are still considered a last resort when standard therapies have failed for patients with progressive heart failure (HF). Although a number of experimental studies have provided robust evidence of its effectiveness, the lack of strong clinical evidence discourages practitioners. Thoracic unilateral sympathectomy has been extensively studied and has failed to show significant clinical improvement in HF patients. Most recently, bilateral sympathectomy effect was associated with a high degree of success in HF models, opening the perspective to be investigated in randomized controlled clinical trials. In addition, a series of clinical trials showed that bilateral sympathectomy was associated with a decreased risk of sudden death, which is an important outcome in patients with HF. These aspects indicates that bilateral sympathectomy could be an important alternative in the treatment of HF wherein pharmacological treatment barely reaches the target dose.

ABSTRACT

OBJECTIVES: To evaluate the effects of sympathectomy on the myocardium in an experimental model. METHODS: The study evaluated three groups of male Wistar rats: control (CT; n=15), left unilateral sympathectomy (UNI; n=15), and bilateral sympathectomy (BIL; n=31). Sympathectomy was performed by injection of absolute alcohol into the space of the spinous process of the C7 vertebra. After 6 weeks, we assessed the chronotropic properties at rest and stress, cardiovascular autonomic modulation, myocardial and peripheral catecholamines, and beta-adrenergic receptors in the myocardium. The treadmill test consisted of an escalated protocol with a velocity increment until the maximal velocity tolerated by the animal was reached. RESULTS: The bilateral group had higher levels of peripheral catecholamines, and consequently, a higher heart rate (HR) and blood pressure levels. This suggests that the activation of a compensatory pathway in this group may have deleterious effects. The BIL group had basal tachycardia immediately before the exercise test and increased tachycardia at peak exercise (p<0.01); the blood pressure had the same pattern (p=0.0365). The variables related to autonomic modulation were not significantly different between groups, with the exception of the high frequency (HF) variable, which showed significant differences in CT vs UNI. There was no significant difference in beta receptor expression between groups. There was a higher concentration of peripheral norepinephrine in the BIL group (p=0.0001), and no significant difference in myocardial norepinephrine (p=0.09). CONCLUSION: These findings suggest that an extra cardiac compensatory pathway increases the sympathetic tonus and maintains a higher HR and higher levels of peripheral catecholamines in the procedure groups. The increase in HF activity can be interpreted as an attempt to increase the parasympathetic tonus to balance the greater sympathetic activity.

ABSTRACT

Abstract Despite the current availability of safe and efficient drugs for treating hypertension, a substantial number of patients are drug-resistant hypertensives. Aiming this condition, a relatively new approach named catheter-based renal denervation was developed. We have now a clinically relevant time window to review the efficacy of renal denervation for treating this form of hypertension. This short review addresses the physiological contribution of renal sympathetic nerves for blood pressure control and discusses the pros and cons of renal denervation procedure for the treatment of resistant hypertension.


Resumo Em que pese a atual disponibilidade de medicamentos seguros e eficientes para o tratamento da hipertensão, um número significativo de pacientes sofre de hipertensão arterial resistente a tratamento medicamentoso. Em vista dessa condição, foi desenvolvida uma abordagem relativamente nova, denominada denervação renal por cateter. Dispomos atualmente de uma janela de tempo clinicamente relevante para analisar a eficácia da denervação renal no tratamento dessa modalidade de hipertensão. A presente revisão aborda a contribuição fisiológica dos nervos renais simpáticos no controle da pressão arterial e discute os prós e contras do procedimento de denervação renal no tratamento da hipertensão resistente.

ABSTRACT

RESUMO Objetivo: Avaliar a qualidade de vida de pacientes submetidos a simpatectomia torácica bilateral de R5 a R8 como forma de tratamento da hiperidrose compensatória (HC) grave e debilitante em pacientes que foram previamente submetidos a simpatectomia torácica bilateral para tratamento da hiperidrose localizada. Métodos: Doze pacientes com hiperidrose compensatória grave e debilitante foram submetidos a simpatectomia estendida no Hospital das Clínicas da Universidade Federal de Pernambuco, Brasil, entre setembro de 2016 e maio de 2019. Os seguintes desfechos foram estudados: nível de satisfação com a operação, escore de qualidade de vida e as possíveis complicações cirúrgicas. Resultados: Houve significativa melhora na qualidade de vida em 66% da amostra. Em todas as esferas de função, foi evidenciada relevância estatística no que se refere ao alívio dos sintomas relacionados à hiperidrose compensatória. Conclusões: A simpatectomia estendida de R5 a R8 mostrou-se efetiva na maioria dos casos operados, caracterizando este procedimento como promissor, podendo, após estudos futuros, ser incluído como uma opção terapêutica para a hiperidrose compensatória.


ABSTRACT Objective: The purpose of this study was to assess the quality of life of patients who had undergone bilateral thoracic sympathectomy from R5 to R8 as a treatment for severe and debilitating compensatory hyperhidrosis (CH). Methods: Twelve patients with severe and debilitating compensatory hyperhidrosis underwent extended sympathectomy (R5-R8) from September 2016 to May 2019 at the Hospital das Clínicas, Federal University of Pernambuco, Brazil. Outcomes such as the level of patient satisfaction with the operation, quality of life scores as well as postoperative complications were assessed. Results: There has been a substantial improvement in the quality of life score of 66% of the sample. In all four domains, a statistical significant difference was seen, regarding the relief of compensatory hyperhidrosis symptoms. Conclusions: Extended sympathectomy from R5 to R8 was shown to be quite effective in most cases, leading us to believe that this approach could be a therapeutic option for severe compensatory hyperhidrosis.

ABSTRACT

Abstract Objective: Cardiac sympathetic denervation (CSD) using video-assisted thoracoscopy is a therapeutic alternative for cardiac arrhythmias refractory to conventional treatment in patients with ventricular structural heart disease, mainly due to ischemia, and in patients with hereditary conditions associated with sudden death such as long QT syndrome. In general, it is performed in cases with recurrent episodes of ventricular tachycardia or electrical storm, in spite of conventional treatment. The objective of this study is to show the experience of this institution with DSCI in refractory patients to conventional management and the results derived from its application. Methods: This was an observational retrospective study. The records of patients with a history of ventricular arrhythmias treated in our center with pharmacological treatment, catheter ablation, or implantation of an implantable cardioverter-defibrillator (ICD), who underwent video-assisted CSD were analyzed and described. Results: A total of six patients were included in the study. Patients with structural heart disease were the most frequent, median age was 56 � 16 years; 67% were male. The procedure evolved without complications in any of the patients and an overall significant improvement was observed. A 24-month follow-up was conducted; two patients had recurrence episodes presenting as slow ventricular tachycardia without severe symptoms and a third patient presented an episode of ventricular fibrillation aborted by the ICD. Conclusion: Video-assisted CSD should be considered as a treatment option for patients with potentially dangerous arrhythmias that do not respond to conventional treatment, especially in recurrent ventricular tachycardia.


Resumen Objetivo: La denervación simpática cardiaca izquierda (DSCI) por toracoscopia se ha convertido en una alternativa terapéutica para el manejo de arritmias cardíacas refractarias al tratamiento convencional en pacientes con cardiopatía estructural, principalmente isquémicos, y enfermedades hereditarias asociadas con muerte súbita como el síndrome de QT largo. Generalmente se realiza en quienes manifiestan episodios recurrentes de arritmias ventriculares o incluso tormenta eléctrica a pesar del tratamiento convencional. El objetivo de este estudio es mostrar la experiencia de esta institución con la DSCI en pacientes refractarios al manejo convencional y los resultados derivados de su aplicación. Métodos: Se revisaron los registros de 6 pacientes con antecedente de arritmias ventriculares tratados previamente con medicamentos y en algunos casos con ablación con catéter y la mayoría con desfibrilador automático implantable, que fueron llevados DSCI por toracoscopia video-asistida (VATS). Resultados: La principal enfermedad de base fue la cardiopatía estructural, la indicación más prevalente fue tormenta arrítmica incontrolable, la edad promedio fue de 56 +- 16 años, el 67% de los individuos fueron hombres. Este procedimiento no mostró complicaciones en ninguno de los pacientes y se encontró mejoría sintomática en todos los casos. Se realizó seguimiento por 24 meses; dos pacientes tuvieron recurrencias por taquicardia ventricular lenta sin síntomas severos y uno por fibrilación ventricular. Conclusion: La DSCI por VATS debe considerarse como opción terapéutica para pacientes con arritmias de difícil manejo.

ABSTRACT

Se define la hiperhidrosis como una excesiva sudoración en respuesta a estímulos térmicos o emocionales más allá de los requerimientos fisiológicos, con una incidencia de 2% a 4% en la población mundial. Si bien existen varios tipos de tratamientos, la opción quirúrgica brinda excelentes resultados con bajas tasas de recidiva. Pacientes y método: estudio retrospectivo de 190 simpaticectomías torácicas videoasistidas realizadas desde 2003 hasta 2013, totalizando 95 pacientes. Se realizó una encuesta mediante un cuestionario sobre calidad de vida y sobre la severidad de los síntomas. Resultados: se logró recabar el cuestionario en 58 pacientes (30% hombres y 70% mujeres) con una media de edad de 25 años. El 90% se dio de alta entre las 24 y 48 horas del posoperatorio. Del total de pacientes, 72% presentaba hiperhidrosis severa. Del procedimiento podemos decir que dos pacientes presentaron recurrencia y un paciente refirió disconformidad por hipersequedad de la piel. El 80% presentó algún tipo de hiperhidrosis compensadora, no siendo este un síntoma de preocupación mayor por parte de los pacientes. No hubo complicaciones de procedimiento. Respecto a la calidad de vida, era mala o regular en el 90% de los pacientes, mejorando en el posoperatorio, siendo buena o muy buena en el 95%. El 94% de los pacientes están conformes o muy conformes con el procedimiento y sus resultados. Como conclusión, podemos establecer que la simpaticectomía torácica bilateral para el tratamiento de la hiperhidrosis es un método altamente seguro y efectivo. (AU)


Hyperhidrosis is defined as excessive sweating as a response of thermal or emotional stimuli beyond physiological requirements, and it incidence is 2 to 4% of the global population. In spite of there being several kinds of treatment, surgery provides excellent results with low relapse rates. Method: retrospective study of 190 video-assisted thoracic sympathectomies performed from 2003 until 2013, accounting for 95 patients. A survey was conducted through a quality-of-life questionnaire and questions on the severity of symptoms. Results: 58 patients completed the survey (30% men and 70% women) with an average age of 25 years old. 90% were discharged from hospital between 24 and 48 hours after surgery. 72% of patients presented severe hyperhidrosis. Based on the procedure, we may state 2 patients presented recurrence and only one patient declared to be uncomfortable with the hyper-dryness of skin. 80% of patients presented some kind of compensating hyperdidrosis, being the no reason for concern among patients. There were no complications arising from the procedure. As to the quality of life it used to be bad or fair in 90% of patients, and improved in the postoperative period, being it good or very good in 95% of them. 94% of patients are satisfied or very satisfied with the procedure and its results. As a conclusion, we may sat that bilateral thoracic sympathectomy is a highly safe and effective method to treat hyperhidrosis.

ABSTRACT

The autonomic nervous system plays critical roles in maintaining homeostasis in humans, directly regulating inflammation by altering the activity of the immune system. The cholinergic anti-inflammatory pathway is a well-studied neuroimmune interaction involving the vagus nerve. CD4-positive T cells expressing β2 adrenergic receptors and macrophages expressing the alpha 7 subunit of the nicotinic acetylcholine receptor in the spleen receive neurotransmitters such as norepinephrine and acetylcholine and are key mediators of the cholinergic anti-inflammatory pathway. Recent studies have demonstrated that vagus nerve stimulation, ultrasound, and restraint stress elicit protective effects against renal ischemia-reperfusion injury. These protective effects are induced primarily via activation of the cholinergic anti-inflammatory pathway. In addition to these immunological roles, nervous systems are directly related to homeostasis of renal physiology. Whole-kidney three-dimensional visualization using the tissue clearing technique CUBIC (clear, unobstructed brain/body imaging cocktails and computational analysis) has illustrated that renal sympathetic nerves are primarily distributed around arteries in the kidneys and denervated after ischemia-reperfusion injury. In contrast, artificial renal sympathetic denervation has a protective effect against kidney disease progression in murine models. Further studies are needed to elucidate how neural networks are involved in progression of kidney disease.

ABSTRACT

RESUMO A simpatectomia toracoscópica mostrou-se eficaz no alívio da hiperidrose em diversos pacientes, com melhora da qualidade de vida. O conhecimento do quadro clínico de cada paciente, assim como, as possíveis complicações pós-operatórias, são fundamentais para a obtenção de bons resultados. Deste modo, foi realizada uma revisão na base de dados PubMed de artigos publicados entre 2005 e 2019 que apresentavam como temática principal a simpatectomia realizada por videotoracoscopia para o tratamento da hiperidrose, com o objetivo de avaliar o atual estado da arte referente à qualidade de vida pós-operatória, o tempo de cirurgia e as suas complicações. A partir desta análise, verificou-se a importância do nível de secção da cadeia ganglionar simpática em relação aos resultados. As complicações, apesar de ocorrerem, não reduziram o nível de satisfação e qualidade de vida pós-operatória dos pacientes.


ABSTRACT. Thoracic sympathectomy has been effective in relieving hyperhidrosis in several patients, with quality of life improvement. The knowledge of the clinical picture of each patient, as well as the possible postoperative complications, are fundamental to obtain good results. Thus, we performed a review of articles from the PubMed database published between 2005 and 2019 that presented, as the main topic, thoracoscopy sympathectomy for the treatment of hyperhidrosis, with the objective of evaluating the current state of art referring to postoperative quality of life, surgical time and its complications. From this analysis, we verified the importance of the level of sympathetic ganglion chain section in relation to results. The complication, although occurring, did not reduced the postoperative level of satisfaction or patients' quality of life.

ABSTRACT

ABSTRACT Objective: To conduct a longitudinal investigation of cardiac vagal activity (CVA) by measuring resting HR and calculating the cardiac vagal index (CVI) in individuals undergoing sympathectomy for the treatment of primary hyperhidrosis. Methods: This was a descriptive longitudinal study involving 22 patients, 13 of whom were female. The mean age was 22.5 ± 8.8 years. The palms, soles, and axillae were the most commonly affected sites. Resting HR was measured by an electrocardiogram performed 20 min before the 4-second exercise test (4sET), which was used in order to evaluate CVA at three different time points: before surgery, one month after surgery, and four years after surgery. Results: Resting HR (expressed as mean ± SE) was found to have decreased significantly at 1 month after surgery (73.1 ± 1.6 bpm before surgery vs. 69.7 ± 1.2 bpm at one month after surgery; p = 0.01). However, the HR values obtained at four years after surgery tended to be similar to those obtained before surgery (p = 0.31). The CVI (expressed as mean ± SE) was found to have increased significantly at one month after surgery (1.44 ± 0.04 before surgery vs. 1.53 ± 0.03 at one month after surgery; p = 0.02). However, the CVI obtained at four years after surgery tended to be similar to that obtained before surgery (p = 0.10). Conclusions: At one month after sympathectomy for primary hyperhidrosis, patients present with changes in resting HR and CVA, both of which tend to return to baseline at four years after surgery.


RESUMO Objetivo: Investigar longitudinalmente o comportamento da atividade vagal cardíaca (AVC) por meio da FC de repouso e do índice vagal cardíaco (IVC) de indivíduos submetidos à simpatectomia para o tratamento de hiperidrose primária. Métodos: Estudo de natureza descritiva e longitudinal que avaliou 22 pacientes (13 mulheres), com média de idade de 22,5 ± 8,8 anos. Os locais mais afetados eram as mãos, pés e axilas. A FC de repouso média foi mensurada através de eletrocardiograma 20 min antes do teste de exercício de 4 segundos (T4s), que foi utilizado para a avaliação da AVC em três momentos: antes da cirurgia, um mês após a cirurgia e quatro anos após a cirurgia. Resultados: A média ± erro-padrão da FC de repouso apresentou uma redução significativa entre a avaliação pré-operatória e um mês após a cirurgia (73,1 ± 1,6 bpm vs. 69,7 ± 1,2 bpm; p = 0,01), tendendo a retornar aos valores pré-operatórios quatro anos após a cirurgia (p = 0,31). Houve um aumento significativo do IVC entre o pré-operatório e um mês após a cirurgia (1,44 ± 0,04 vs. 1,53 ± 0,03; p = 0,02), tendendo também a retornar próximo aos valores do pré-operatório após quatro anos da cirurgia (p = 0,10). Conclusões: A simpatectomia resultou em alteração na FC de repouso e na AVC um mês após a cirurgia, retornando, após quatro anos, aos valores próximos do pré-operatório.

ABSTRACT

PREFACE: Videothoracoscopic sympathectomy (VTS) is the gold standard treatment for the upper extremity hyperhidrosis (HH) because it is safe and has good results. OBJECTIVE: To evaluate retrospectively the long term results of VTS for the treatment of HH on 50 operated patients in the Maule Region from the year 2003 to september of 2015. METHODS: For axillary HH a T2 to T4 VTS was performed, and T3 VTS for palmar HH. All the patients were operated bilaterally through 2 axillary ports. The operatory sucess was evaluated through the persistence or not of sweating of the palm and armpit. Also, all the complications associated were registered. RESULTS: The procedure was successful in 96% of the patients, who reached anhidrosis in the palms and armpits. The most common complication was compensatory sweating, minimal to mild in 28% of the patients aproximately, severe only in one case; intense post operatory pain in 3 cases and sympathyc reinervation in 2 cases. There was no Infection, Horner syndrome, inthercostal arthery injury or mortality reported. CONCLUSION: The billateral VTS is an effective and safe procedure to obtain anhidrosis in patients with upper extremity hyperhidrosys.

ABSTRACT

Abstract Background and objectives Ischemic cardiomyopathy is characterized by imbalance between supply and demand of myocardial oxygen. Endoscopic transthoracic sympathectomy is a therapeutic option indicated in refractory cases. However, the patient's position on the operating table may favor ischemic coronary events triggering the Bezold-Jarisch reflex. Case report A female patient, 47 years old, with refractory ischemic cardiomyopathy, admitted to the operating room for endoscopic transthoracic sympathectomy, developed the Bezold- Jarisch reflex with severe bradycardia and hypotension after placement in semi-sitting position to the procedure. Conclusion Bradyarrhythmia, hypotension, and asystole are complications potentially associated with patient placement in a semi-sitting position, particularly in cases with previous ischemic heart disease.


Resumo Justificativa e objetivos A cardiomiopatia isquêmica caracteriza-se pelo desbalanço entre a oferta e o consumo de oxigênio pelo miocárdio. A simpatectomia transtorácica endoscópica é uma opção terapêutica indicada nos casos refratários. Contudo, a posição do paciente na mesa cirúrgica pode favorecer eventos coronarianos isquêmicos e deflagrar o reflexo de Bezold-Jarisch. Relato de caso Paciente do sexo feminino, 47 anos, portadora de cardiomiopatia isquêmica refratária, admitida na sala de cirurgia para simpatectomia transtorácica endoscópica, deflagrou o reflexo de Bezold-Jarisch e desenvolveu bradicardia e hipotensão graves logo após colocação em posição semissentada para o procedimento. Conclusão Bradiarritmia, hipotensão e assistolia são complicações potencialmente associadas à colocação do paciente em posição semissentada, especialmente nos casos em que há prévio comprometimento isquêmico do coração.

ABSTRACT

RESUMO Objetivo: avaliar a qualidade de vida de pacientes submetidos à simpatectomia por videotoracoscopia para tratamento de hiperidrose primária. Métodos: foram avaliados os pacientes submetidos à simpatectomia por videotoracoscopia para tratamento de hiperidrose primária pela equipe de cirurgia torácica do Hospital Universitário Gafrée e Guinle-UNIRIO entre julho de 2004 e agosto de 2013. Foi aplicado um questionário sobre qualidade de vida relacionada à hiperidrose desde o pré-operatório até um ano após a operação. Resultados: o questionário foi aplicado em 122 pacientes com média de idade de 25 anos, sendo 57% mulheres. Quanto à severidade da hiperidrose primária, 83% dos pacientes referiam como pouco tolerável ou intolerável, associada com grande limitação da qualidade de vida, sendo esta pobre ou muito pobre em 82% dos casos. No pós operatório a hiperidrose compensatória ocorreu em 78% dos pacientes, entretanto foi considerada como imperceptível ou pouco perceptível por 85% destes pacientes, classificando-a como aceitável. Em 15% dos pacientes a hiperidrose compensatória foi classificada como perturbadora. Conclusão: a simpatectomia videotoracoscópica melhora a qualidade de vida dos pacientes com hiperidrose primária. A hiperidrose compensatória transitória ocorreu na maioria dos pacientes, mas não alterou de maneira significativa a melhora da qualidade de vida.


ABSTRACT Objective: to evaluate the quality of life of patients undergoing video-assisted thoracoscopy for primary hyperhidrosis. Methods: we evaluated the patients who underwent thoracoscopic sympathectomy to treat primary hyperhidrosis by the team of thoracic surgery at the University Hospital Gaffrée and Guinle - UNIRIO between July 2004 and August 2013. It was applied a questionnaire about quality of life related to hyperhidrosis since preoperative period until one year after the surgery. Results: one hundred twenty two patients answered the questionnaire, with a mean age of 25 years, 57% of whom were women. In relation to severity of primary hyperhidrosis, 83% of the patients reported as tolerable or somewhat tolerable associated with major limitation of quality of life, which it was poor or very poor in 82% of cases. Postoperative compensatory hyperhidrosis occurred in 78% of patients, but it was regarded as invisible or barely noticeable for 85% of these patients, classifying it as acceptable. In 15% of patients, the compensatory sweating was classified as disruptive. Conclusion: thoracoscopic sympathectomy improves the quality of life of patients with primary hyperhidrosis. The transitional compensatory hyperhidrosis occurred in most patients, but did not improve significantly the quality of life.

ABSTRACT

Abstract Background: Radiofrequency ablation of renal sympathetic nerve (RDN) shows effective BP reduction in hypertensive patients while the specific mechanisms remain unclear. Objective: We hypothesized that abnormal levels of norepinephrine (NE) and changes in NE-related enzymes and angiotensinconverting enzyme 2 (ACE2), angiotensin (Ang)-(1-7) and Mas receptor mediate the anti-hypertensive effects of RDN. Methods: Mean values of systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) were assessed at baseline and follow-up. Plasma and renal norepinephrine (NE) concentrations were determined using highperformance liquid chromatography with electrochemical detection, and levels of NE-related enzyme and ACE2-Ang(1-7)- Mas were measured using real time PCR, Western blot and immunohistochemistry or Elisa in a hypertensive canine model fed with high-fat diet and treated with RDN. The parameters were also determined in a sham group treated with renal arteriography and a control group fed with normal diet. Results: RDN decreased SBP, DBP, MAP, plasma and renal NE. Compared with the sham group, renal tyrosine hydroxylase (TH) expression was lower and renalase expression was higher in the RDN group. Compared with the control group, renal TH and catechol-o-methyl transferase (COMT) were higher and renalase was lower in the sham group. Moreover, renal ACE2, Ang-(1-7) and Mas levels of the RDN group were higher than those of the sham group, which were lower than those of the control group. Conclusion: RDN shows anti-hypertensive effect with reduced NE and activation of ACE2-Ang(1-7)-Mas, indicating that it may contribute to the anti-hypertensive effect of RDN.


Resumo Fundamentos: A denervação simpática renal por radiofrequência (DSR) mostra redução eficaz da pressão arterial (PA) de pacientes hipertensos, ainda que os mecanismos específicos permaneçam obscuros. Objetivo: Fizemos a hipótese de que níveis alterados de noradrenalina (NA) e mudanças nas enzimas relacionadas à NA e enzima conversora de angiotensina 2 (ECA-2), angiotensina (Ang)-(1-7) e receptor Mas são mediadores dos efeitos antihipertensivos da DSR. Métodos: Foram avaliados os valores médios de pressão arterial sistólica (PAS), pressão arterial diastólica (PAD) e pressão arterial média (PAM) no início e durante o seguimento. Foram medidas as concentrações plasmática e renal de noradrenalina (NA) por cromatografia líquida de alta eficiência com detecção eletroquímica, e os níveis de enzima relacionada à NA e ECA2-Ang-(1-7)-Mas através de PCR em tempo real, Western blot e imunohistoquímica ou Elisa em um modelo canino de hipertensão que recebeu ração rica em gordura e foi tratado com DSR. Os parâmetros também foram determinados em um grupo de cirurgia simulada submetido à arteriografia renal e em um grupo controle que recebeu dieta normal. Resultados: DSR causou diminuição da PAS, PAD, PAM e das concentrações plasmática e renal de NA. Em comparação ao grupo placebo, a expressão da tirosina hidroxilase (TH) renal foi menor e a da renalase foi maior no grupo DSR. Em comparação ao grupo controle, os níveis de TH renal e de catecol-o-metil-transferase (COMT) foram maiores e os de renalase foram menores no grupo cirurgia simulada. Além disso, os níveis renais de ECA2, Ang-(1-7) e Mas foram maiores no grupo DSR do que no grupo cirurgia simulada, que, por sua vez, foram menores do que no grupo controle. Conclusões: A DSR mostra efeitos anti-hipertensivos com redução da NA e ativação da ECA2-Ang-(1-7)-Mas, o que indica que pode contribuir com o efeito anti-hipertensivo da DSR.
