Houve a análise das principais medidas governamentais de caráter legal após esse episódio, visando responder ao seguinte questionamento: a partir das evidências existentes quanto às causas dos incêndios florestais no Pantanal Mato-grossense, as medidas adotadas pelo Estado brasileiro são aptas a prevenir incêndios florestais e a assegurar a reparação do dano ambiental a partir do desastre ocorrido? As medidas adotadas pelo governo brasileiro foram levantadas por meio de consulta legislativa e notícias veiculadas nos sítios eletrônicos oficiais dos poderes legislativo e executivo na esfera federal e estadual. A análise das medidas foi feita considerando as ações de caráter preventivo e de combate, em relação às principais causas dos incêndios ocorridos no ano de 2020. Entre as considerações finais do presente estudo...

Useful advice on how to gain exposure to this surgical specialty and suggestions on relevant investigations and diagnostic procedures to see are provided. An approach to the clinical assessment of patients in cardiothoracic outpatients is outlined, including focused history taking and clinical examination for both cardiac and thoracic surgical patients—a rich environment for eliciting clinical signs. Acute cardiothoracic presentations are covered with particular emphasis on acute aortic dissection (including classification) and chest trauma (including life-threatening traumatic chest injuries). Cardiothoracic surgery is an exciting environment for medical students interested in surgery. This chapter describes the principles of the most common operations: coronary artery bypass grafting, aortic valve replacement, mitral valve repair, lobectomy, video-assisted thoracic surgery, bronchoscopy, medi...

Com uma estrutura de administração participativa, a rede de informações do SNUC sofre com a falta de comunicação entre os diferentes órgãos. Aliado a desatualização dos domínios oficiais, o sistema falha onde deveria prover dados das unidades de conservação (UC's). O Ministério do Meio Ambiente, responsável por compilar dados referentes a todas unidades de conservação possui um grande déficit de informações referentes as UC's do estado de Mato Grosso, 46 no total. Na base de dados do ICMBio 14 unidades federais são omitidas. Quanto ao plano de manejo, 35 unidades estaduais e 17 unidades federais não possuem o documento. Independentemente da crítica situação das UC's no estado, referente a falta de planos de manejo, as mesmas podem gerar benefícios, como a conservação da biodiversidade local.

Atypical forms are a diagnostic challenge and recent cardiac imaging techniques, such as cardiac CT and magnetic resonance imaging, can make an important contribution. We present a review of this disease based on two case reports.

The diagnostic was made by angiography. He was submitted to a Bentall's procedure; replacement of the ascending aorta by a conduit and of aortic valve by a mechanical prosthesis with reimplantation of coronary arteries into the conduit. The only complication was atrial fibrillation with fast ventricular response. Nowadays he is clinically well, in NYHA class I. The authors make some considerations about AAE, its surgical treatment and its results.

This procedure was used on 63 grafts (30 in the LAD; 20 in the LCX; 13 in the RCA) in 32 patients with a mean age of 56 +/- 8 years, all of whom were referred to our department for postoperative management or evaluation. The CT scanner used was Toshiba TCT-60A with a scan time of 3 sec, 5 mm thick slices, and 512 x 512 pixels. CT scans without contrast enhancement were obtained from the level of the aortic arch to the left ventricle. Eight sec after 30 ml of contrast media was injected at a rate of 3 ml/sec into an antecubital vein, 5 scans were made at the same level of the pulmonary artery truncus. After positioning the regions of interests on the ascending aorta and grafts, we obtained time-density curves (TDCs) and compared the data with those recorded from an intraoperative electromagnetic flow meter (EMF). Fifty grafts were angiographically patent. The appearance time, build-up time, peak time, disappearance time and peak densities obtained from TDCs of grafts did not correlate with the flow volumes measured by EMF. Patent grafts were easily identified visually, without contrast enhancement (sensitivity; 88%, specificity; 100%, accuracy; 91%). Occluded grafts were not imaged on CT, either with or without contrast enhancement. We concluded that the TDCs of grafts obtained by CT are of no value for predicting the graft flow, and that plain CT without contrast enhancement is sufficiently useful for assessing the patency of such grafts.

This was an exploratory correlational study of 91 patients (71 men and 20 women) who underwent CABG (aortocoronary anastomosis) by sternotomy. Mean age was 63.8 + 9.6 years (between 39 and 84). The following instruments were used: visual analogical scales at 24, 48 and 96 hours of post-surgery; demographic characteristics survey; pain expectations scale; perceived support scale; self-efficacy scale, Mental Inventory (5 items); health perception scale; and satisfaction with treatment, doctors and nurses (American Pain Society questionnaire) at 96 hours after surgery. Patients who had presented high expectations of pain, perceived more support, presented high levels of self-efficacy to deal with pain or were male, felt less pain. Furthermore, patients who presented better mental health, perceived their general health as being good, or ex...

Material and methods: From September 2001 to September 2003, thirty-three very high-risk patients were operated on in our department, which represents 1.6% of all the surgical activity during that period of time, being 17 male and 16 female, with an average of 69 years old (maximum 86 and minimum 32). Diagnosis includes: post infarction CIV 5, coronary insufficiency 11, aortic dissection 3, mitral prosthesis 3, valvular disease 9, aortic prosthesis disfunction 2. Fifteen patients underwent an emergency procedure, 12 were urgent and the remaining 6 were electively operated on. Results: Overall post-operative mortality was 12 patients (36%), being 6 emergent, 5 urgent and 1 elective patient. Patients who survived the operation had longer intensive care and hospital admission periods, which will be analyzed in detail. Conclusion: Surgery can be justifie...

Laboratory tests revealed anemia, leukocytosis, thrombocytopenia, high sedimentation rate and D-dimers, hypoxemia and hypocapnea. He also had sinus tachycardia, rSR' in V1 and an opacity on the periphery of the right pulmonary field. Blood and urine cultures were negative, as were serological markers. The echocardiogram showed a large mass adhering to the tricuspid valve, suggestive of myxoma. The patient underwent surgery, and anatomopathological examination of the mass showed it to be a bacterial vegetation, with no agent isolated. It is pointed out that differential diagnosis is difficult between a myxoma with systemic symptomatology associated with a possible pulmonary embolism, and tricuspid endocarditis with negative blood culture associated with a septic pulmonary embolism, which turned out to be the diagnosi...

Relata-se o caso de um rapaz de 14 anos, assintomático, referenciado à consulta após detecção de imagem nodular na base do pulmão direito num radiograma de tórax. A tomografia computorizada (TC) mostrou, no pulmão direito, formação redonda de média densidade com centro cavitado. Após um ano de seguimento, mantinha-se assintomático, sendo a imagem radiológica sobreponível. Em conjunto com a equipa de cirurgia cardiotorácica foi decidido proceder a biópsia excisional. O exame histológico revelou um carcinoma bronquíolo-alveolar mucinoso associado a CPAM tipo 1. Perante este resultado, o doente foi submetido a lobectomia inferior direita. No exame histológico do restante lobo, não se Abstract Congenital pulmonary airway malformation (CPAM) is a rare entity with potential for malignant transformation. We describe the case of a fourteen-year-old boy evaluated for the presence of a nodular image on the right lung on the chest x-ray. Computerized Tomography (CT) showed a round lesion of medium density with cavitation on the right lung. After one year of follow-up the patient was still asymptomatic and the image was similar. With the agreement of the cardiothoracic surgeons an excisional biopsy was performed. The histological examination revealed a mucinous bronchioloalveolar carcinoma associated with a type 1 CPAM. The patient was then submitted to right inferior lobectomy. After two years follow-up he is asymptomatic and free of complications. To the authors best knowledge this is the first case reported in Carcinoma bronquíolo-alveolar associado a malformação congénita das vias aéreas pulmonares em adolescente assintomático Bronchioloalveolar carcinoma associated with congenital pulmonary airway malformation in an asymptomatic adolescent Recebido para publicação/received for publication: 07.09.21 Aceite para publicação/accepted for publication: 07.11.02
