Abstract BACKGROUND: Endoscopic thoracic sympathectomy is the definitive surgical treatment for hyperhidrosis and a nationwide study has suggested that cultural and socioeconomic factors play a role in the numbers of operations performed. Thus, there is a need to evaluate local data in order to understand the local epidemiology and trends in hyperhidrosis treatment. OBJECTIVE: To study the epidemiology of sympathectomy for treating hyperhidrosis in São Paulo, the largest city in Brazil. DESIGN AND SETTING: Population-based retrospective cross-sectional study. METHODS: Data on sympathectomies for treating hyperhidrosis between 2008 and 2018 were assessed from the database of the Municipal Health Department of São Paulo, Brazil. RESULTS: 65.29% of the patients were female, 66.2% were aged between 20 and 39 years and 37.59% had registered with addresses outside São Paulo. 1,216 procedures were performed in the city of São Paulo from 2008 to 2018, and 78.45% of them were in only two public hospitals. The number of procedures significantly declined over the years (P = 0.001). 71.63% of the procedures were associated with 2-3 days of hospital stay, only 78 intensive care unit days were billed and we did not observe any intra-hospital death. CONCLUSION: The profile of patients operated on in São Paulo (young women) is similar to that described in other populations. Sympathectomy is a very safe procedure, with no mortality in our series. There was a decreasing trend in the number of surgeries over the years.

Resumo Contexto O implante de filtro de veia cava é considerado um procedimento de baixa complexidade, o que pode resultar em indicação excessiva. No entanto, não é isento de complicações a curto e longo prazo. Objetivos Avaliar as taxas de implantes de filtro de veia cava realizados pelo Sistema Único de Saúde e a origem geográfica e mortalidade intra-hospitalar dos pacientes. Métodos Foi conduzida uma análise em um banco de dados públicos referente às taxas de implantes de filtro de veia cava realizados de 2008 a 2018 na cidade de São Paulo, utilizando o sistema de big data. Resultados Foram analisados 1.324 implantes de filtro de veia cava financiados pelo Sistema Único de Saúde. Identificou-se tendência de aumento da taxa de implantação até 2010 e de redução dos números após esse período. Do total de pacientes, 60,5% eram do sexo feminino; 61,75% tinham menos de 65 anos; e 34,07% possuíam endereço oficial em outra cidade ou estado. A taxa de mortalidade intra-hospitalar foi de 7,4%. Conclusões Observamos aumento das taxas de implante de filtro de veia cava até 2010 e redução das taxas após esse período, o que coincide com o ano em que a organização norte-americana Food and Drug Administration publicou uma recomendação para melhor avaliar as indicações de filtros.

Abstract Background Vena cava filter implantation is considered a simple procedure, which can lead to overuse and over-indication. It is nevertheless associated with short and long-term complications. Objectives The goals of this study were to evaluate rates of vena cava filter implantation conducted by Brazil’s Unified Public Health System, analyzing in-hospital mortality and migration of patients from other cities seeking medical attention in São Paulo. Methods This study analyzed all vena cava filter procedures conducted from 2008 to 2018 in the city of São Paulo and registered on the public database using a big data system to conduct web scraping of publicly available databases. Results A total of 1324 vena cava filter implantations were analyzed. 60.5% of the patients were female; 61.7% were under 65 years old; 34.07% had registered addresses in other cities or states; and there was a 7.4% in-hospital mortality rate. Conclusions We observed an increase in the rates of use of vena cava filters up to 2010 and a decrease in rates from that year onwards, which coincides with the year that the Food and Drug Administration published a recommendation to better evaluate vena cava filter indications.

Resumo Contexto No Brasil, a mortalidade por aneurisma de aorta aumentou 16,8% de 1990 a 2015. São Paulo é a maior cidade do Brasil, e cerca de 5 milhões de pessoas dependem do sistema público de saúde. Objetivos Análise epidemiológica das cirurgias do aneurisma de aorta abdominal na cidade de São Paulo. Métodos As cirurgias para correção do aneurisma de aorta infrarrenal realizadas no período de uma década (de 2008 a 2017) foram estudadas utilizando-se plataformas publicamente disponíveis do Sistema Único de Saúde e do Departamento de Informática do Sistema Único de Saúde. Resultados Foram analisados 2.693 procedimentos, entre os quais 66,73% eram endovasculares. Entre os pacientes, houve predominância do sexo masculino (78,7%) e daqueles com 65 anos ou mais (70,7%). Um total de 64,02% eram admissões hospitalares eletivas. Ocorreram 288 óbitos hospitalares (mortalidade: 10,69%). A mortalidade durante a internação foi menor para cirurgia endovascular do que para cirurgia aberta tanto no contexto eletivo (4,13% versus 14,42%) quanto urgente (9,73% versus 27,94%) (p = 0,019). O maior volume (n = 635) apresentou menor mortalidade intra-hospitalar (3,31%). Foi pago um total de $24.835.604,84, sendo uma média de $2.318,63 para cirurgia abertura eletiva, $3.420,10 para cirurgia abertura de emergência, $12.157,35 para cirurgia endovascular eletiva e $12.969,12 para cirurgia endovascular na urgência. Os custos dos procedimentos endovasculares foram estatisticamente superiores aos valores pagos para as cirurgias abertas (p < 0,001). Conclusões Foram realizadas duas vezes mais cirurgias endovasculares do que abertas, as quais apresentaram menor tempo de internação e menor mortalidade.

Abstract Background From 1990 to 2015, mortality from aortic aneurysms increased 16.8% in Brazil. São Paulo is the largest city in Brazil and about 5 million people depend on the public health system there. Objectives To conduct an epidemiological analysis of abdominal aortic aneurysm surgeries in the city of São Paulo. Methods Infra-renal aortic aneurysm procedures performed over a decade (from 2008 to 2017) were studied using publicly-available platforms from the Unified Health System and DATASUS. Results 2693 procedures were analyzed; 66.73% were endovascular; 78.7% of patients were male; 70.7% were aged 65 years or more; 64.02% were elective hospital admissions. There were 288 in-hospital deaths (mortality: 10.69%). In-hospital mortality was lower for endovascular surgery than for open surgery; both for elective (4.13% versus 14.42%) and urgent (9.73% versus 27.94%) (p = 0.019) admissions. The highest volume hospital (n = 635) had the lowest in-hospital mortality (3.31%). USD 24,835,604.84 was paid; an average of $ 2,318.63 for elective open, $ 3,420.10 for emergency open, $ 12,157.35 for elective endovascular and $ 12,969.12 for urgent endovascular procedures. Endovascular procedure costs were statistically higher than the values paid for open surgeries (p <0.001). Conclusions Endovascular surgeries were performed twice as often as open surgeries; they had shorter hospital stays and lower mortality.

SUMMARY OBJECTIVES: The aim of this study was to evaluate the epidemiology of varicose vein stripping in Brazil’s largest city, São Paulo. METHODS: Open and anonymous data regarding varicose vein surgeries between 2008 and 2018 were evaluated from the TabNet platform of the Municipal Health Secretary of São Paulo, Brazil. RESULTS: Most patients were female and adults. A total of 66,577 varicose vein surgeries were performed in public hospitals and outpatient clinics in São Paulo, with a statistically significant increase for both unilateral (p=0.003) and bilateral (p<0.001) procedures. Since 2016, unilateral procedures have been performed more frequently than bilateral procedures. Most procedures were associated with same-day (54.8%) or next-day (32%) discharge. The in-hospital mortality rate was 0.0045%. The total amount reimbursed was $20,693,437.94, corresponding to a mean value of $310.82 per procedure. CONCLUSION: Surgeries to treat chronic vein disease totaled 66,577 in 11 years, demanding $20,693,437.94 from the public health system. The majority of treated patients were female, over 40 years of age, and local residents. Procedure rates have increased over the years. The in-hospital mortality rate was very low (0.0045%).

RESUMO Objetivo Avaliar o potencial de liderança de médicos ativos de um hospital público na cidade de São Paulo. Métodos Estudo-piloto descritivo, no qual foram selecionados aleatoriamente 40 médicos assistentes e residentes para receberem o link com convite eletrônico da empresa Caliper Estratégias Humanas do Brasil. Aos que o aceitaram, foi encaminhado o link para preenchimento de avaliação de personalidade focada no trabalho, composta por 112 alternativas relativas a 21 domínios de 4 áreas de desempenho. De acordo com Questionário Perfil Caliper, as medidas ipsativas expressas em percentual são distribuídas em uma escala do tipo Likert, e são determinadas três categorias em relação às tendências comportamentais no trabalho: necessidade de aprimoramento, potencial moderado e alto potencial. Resultados A taxa de adesão dos médicos convidados ao estudo foi de 47,5% (19 médicos). No domínio liderança, a necessidade de aprimoramento ultrapassou 30% dos médicos avaliados. No relacionamento interpessoal, apenas 18,4% dos médicos assistentes necessitavam de aprimoramento e, no grupo dos médicos residentes, 37% necessitavam aprimoramento. Para resolução de problemas e tomada de decisões, as percentagens de necessidade de aprimoramento foram semelhantes (12,6% versus 14%). Na avaliação da organização pessoal e da administração do tempo, obtivemos percentagens semelhantes entre médicos assistentes e residentes, com necessidade de aprimoramento (14% nos dois grupos) e alto potencial nestas áreas (18,4% e 20% para médicos assistentes e residentes, respectivamente). Conclusão Os médicos avaliados apresentaram alto potencial de liderança em um quarto dos casos, necessitando aprimoramento nas áreas de desempenhos, como relacionamento interpessoal, resolução de problemas, tomada de decisão, organização pessoal e administração do tempo.

ABSTRACT Objective To analyze the leadership potential of physicians in a public hospital in the city of São Paulo. Methods A descriptive pilot study, in which 40 assistant physicians and medical residents were randomly selected to receive an electronic invitation of the company Caliper Estratégias Humanas do Brasil . To those who accepted it, a link was sent to fill out a personality evaluation focused on the work, comprising 112 alternatives related to 21 domains of 4 performance areas. According to the Caliper Profile Questionnaire, the ipsative measures expressed as a percentage are distributed on a Likert scale, and three categories are established based on behavioral tendencies at work: need for improvement, moderate and high potential. Results A total of 47.5% of physicians invited accepeted taking part in the study. Regarding to leadership, the need for improvement was over 30% among the evaluated physicians. In the interpersonal relationship analysis, only 18.4% of assistant physicians and 37% of medical residents required improvement. The percentage of physicians who needed improvement in problem-solving and decision-making was similar among the assistant and resident physicians (12.6% versus 14%). In the evaluation of personal organization and time management, we obtained similar percentages in assistant physicians and residents who needed improvement (14% in both groups). High potential leadership was observed in these domains (18.4% and 20% for assistant physicians and residents, respectively). Conclusion The physicians assessed presented high leadership potential in 25% of the cases, requiring improvement in the performance domains, such as interpersonal relationship, problem solving, decision-making, personal organization and time management.

RESUMO OBJETIVO Este estudo tem como objetivo correlacionar os dados demográficos, os diferentes graus clínicos da insuficiência venosa crônica (Ceap), com achados ultrassonográficos de refluxo da junção safenofemoral (JSF) e os achados anatomopatológicos do segmento proximal da veia safena magna (VSM) extraído de pacientes com insuficiência venosa crônica (IVC) primária submetidos à safenectomia magna para correção de varizes dos membros inferiores. MÉTODO Estudo prospectivo de 84 pacientes e 110 membros submetidos à safenectomia magna para o tratamento de varizes de membros inferiores, correlacionando a sua classificação clínica Ceap, presença de refluxo na JSF ao ultrassom Doppler e alterações histopatológicas. Comparamos ainda os achados histopatológicos da VSM proximal retirada dos pacientes com IVC com grupo controle de VSM normal retirada de cadáveres. RESULTADOS Média de idade dos pacientes foi maior nos Ceaps avançados quando comparado Ceap C2 (46,1 anos) com C4 (55,7 anos) e C5-6 (66 anos), e pacientes C3 (50,6 anos) com C5-6. A espessura da parede da VSM normal (média de 839,7 micrômetros) foi significativamente menor do que das VSM varicosas (média de 1.609,7 micrômetros). As análises de correlação da presença do refluxo em JSF com a classificação clínica ou achado histopatológico não demostraram ser estatisticamente significativas. CONCLUSÕES Quanto maior a idade, mais avançada é a classificação clínica da IVC dos pacientes. A espessura da parede da crossa da VSM é maior nos pacientes com IVC e essas alterações não se correlacionam com a classificação clínica da doença ou com a presença de refluxo na JSF ao ultrassom Doppler.

SUMMARY OBJECTIVE This study aims to correlate the demographic data, different clinical degrees of chronic venous insufficiency (CEAP), ultrasound findings of saphenofemoral junction (SFJ) reflux, and anatomopathological findings of the proximal segment of the great saphenous vein (GSV) extracted from patients with primary chronic venous insufficiency (CVI) submitted to stripping of the great saphenous vein for the treatment of lower limb varicose. METHOD This is a prospective study of 84 patients (110 limbs) who were submitted to the stripping of the great saphenous vein for the treatment of varicose veins of the lower limbs, who were evaluated for CEAP clinical classification, the presence of reflux at the SFJ with Doppler ultrasonography, and histopathological changes. We study the relationship between the histopathological findings of the proximal GSV withdrawal of patients with CVI with a normal GSV control group from cadavers. RESULTS The mean age of the patients was higher in the advanced CEAPS categories when comparing C2 (46,1 years) with C4 (55,7 years) and C5-6(66 years), as well as C3 patients (50,6 years) with C5-6 patients. The normal GSV wall thickness (mean 839,7 micrometers) was significantly lower than in the saphenous varicose vein (mean 1609,7 micrometers). The correlational analysis of reflux in SFJ with clinical classification or histopathological finding did not show statistically significant findings. CONCLUSIONS The greater the age, the greater the clinical severity of the patients. The GSV wall is thicker in patients with lower limb varicose veins, but those histopathological changes are not correlated with the disease’s clinical severity or reflux in the SFJ on a Doppler ultrasound.
