Sociodemographic, laboratory, image data and predictors of gravity risk in patients with COVID-19.

INTRODUCTION: The effects, severity, and prognosis of COVID-19 infections do not follow a linear pattern in different locations, but change according to the epidemiological data and social issues in each region. AIMS: The purpose of the current study is to provide the clinical and epidemiological standard of the population affected by COVID-19 in the city of Juiz de Fora, MG to better understand the disease and its risk factors, in order to enable more appropriate conduct for patients. METHODS: A retrospective observational study was carried out from March to August of 2020, with 266 participants admitted to the emergency department of the Instituto de Clínicas e Cirurgia de Juiz de Fora-Hospital Monte Sinai. Data were tabulated, analyzed, and classified according to the outcome using an ordinal regression model. RESULTS: Among the 266 admitted patients, the most common findings were ground-glass opacifications on chest CT (78.8%), cough (75.6%), fever (58.4%), and rhinorrhea (34.5%). There were greater severity and greater need for hospitalization and admission to the ICU in patients who were male, tachypneic at the time of admission, with older age, and with underlying diseases. CONCLUSION: Collected data allowed for a better understanding of the disease, its severity criteria, and its pattern of affection in Juiz de Fora, MG. More studies based on the analysis of the behavior of COVID-19 in different regions must be carried out, to improve treatment and support to local populations.

Acute arterial occlusion of the lower limb as the main clinical manifestation in a patient with Covid-19 - Case Report.

INTRODUTION: COVID-19 infection may predispose to venous and arterial thromboembolism due to excessive inflammation, hypoxia, immobilization and disseminated intravascular coagulation; however, there are few reports of lower limb ischemia as the main manifestation of the disease. PRESENTATION OF CASE: Male patient, 69 years old, asthmatic, ex-smoker and bearer of systemic arterial hypertension, has been admitted to the emergency department with sudden onset of pain in the right lower limb (RLL), associated with cyanosis and reduced temperature of the limb. He has been tested for COVID-19 in the OR with positive result for IGG and IGM. Computed tomography angiography (AngioCT) was performed, showing signs of arterial embolization to both limbs, right internal iliac artery, and superior mesenteric artery. Faced with the threat of limb loss and the absence of signs and symptoms of visceral ischemia, the patient underwent full anticoagulation and RLL thromboembolectomy and tricompartmental fasciotomy. He was discharged after 7 days of hospitalization and demonstrated no other signs and symptoms of COVID-19, following outpatient follow-up. DISCUSSION: COVID-19 is associated with high risk of thrombotic complications being related to the clinical severity of the patient, with few studies that show symptoms of sudden pain in the lower limb without other complaints. CONCLUSION: Individuals infected with COVID-19 are at risk for arterial thromboembolic events, and knowledge of such cases is essential in order to create specific protocols for prophylaxis of thrombotic events in these patients, in addition to increasing the suspicion of infection in individuals with acute arterial occlusion, mostly during pandemic times.

Adenoid Cystic Carcinoma of the Trachea: A Case Report.

BACKGROUND Adenoid cystic carcinoma of trachea (ACCT) is an unusual low-grade tumor from the tracheal and bronchial wall glands. The histological structure and biological behavior of ACCT are similar to that of tumors found in the salivary glands. ACCT occurs most commonly in the upper trachea, being found in the articular cartilage in the posterior aspect of the trachea. CASE REPORT We describe the case of a 62-year-old male ex-smoker 25 years/pack (abstinence 20 years ago), who began with mild dyspnea 2 years ago, with intense evolution and cough. He was evaluated as an outpatient and was treated for sinusitis and later bronchitis after pulmonary function tests. With the worsening of the aforementioned symptoms, he sought prompt care, with hospitalization and computed tomography (CT) of the chest being indicated, showing an expansive lesion in the anterior wall of the trachea with an extension of approximately 3.1 cm, ending at the level of the carina, measuring 3.4×2.8 cm, with moderate stenosis of the tracheal lumen, with an exophytic component to the mediastinum. Bronchoscopy of the lesion was done, and later immunohistochemistry showed a probable pleomorphic adenoma. However, in a new analysis, after the removal of the surgical specimen, it was observed that it was a ACCT. CONCLUSIONS ACCT is a rare tumor that should be diagnosed as soon as possible in order to ensure its best prognosis. Moreover, it is evident that the analysis of the surgical specimen is sovereign to immunohistochemistry with regard to histological typing.

Video-assisted thoracic sympathectomy: literature review. / Simpatectomia torácica por videotoracoscopia: revisão da literatura.

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.

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.

Longitudinal follow-up of cardiac vagal activity in individuals undergoing endoscopic thoracic sympathectomy / Acompanhamento longitudinal da atividade vagal cardíaca de indivíduos submetidos à simpatectomia torácica endoscópica

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.
