A amiloidose consiste em um depósito de proteínas fibrilares insolúveis em tecidos e órgãos, causando disfunção nos mesmos, e pode contribuir, associada a outros fatores, para formação de complicações, como pseudoaneurisma em locais de punção arterial. O pseudoaneurisma consiste de uma complicação cada vez mais frequente e, por isso, a importância de se identificarem seus fatores de risco, para que, então, sua incidência possa ser minimizada.

Amyloidosis consists of deposition of insoluble fibrillar proteins in tissues and, causing dysfunction. In association with other factors, the condition can contribute to emergence of complications, such as pseudoaneurysms at arterial puncture sites. Pseudoaneurysms are becoming an ever-more common complication, which underscores the importance of identifying risk factors, so that their incidence can be minimized.

A fístula carotídeo-jugular é de ocorrência rara, porém habitualmente causa morbimortalidade. Está associada frequentemente a trauma penetrante, principalmente em razão de lesão por projétil de arma de fogo. Relata-se o caso de um paciente vítima de lesão por projétil de arma de fogo na região cervical esquerda, o que provocou fístula arteriovenosa carotídeo-jugular com oclusão da artéria carótida comum. Foi realizada correção da fístula com ligadura da veia jugular interna e arteriorrafia com remendo de pericárdio bovino na artéria carótida comum esquerda.

Carotid-jugular fistulae are rare, but habitually cause morbidity and mortality. They are often linked with penetrating trauma, primarily caused by gunshots. This report describes the case of a patient who was the victim of a gunshot wound to the left cervical area, provoking a carotid-jugular arteriovenous fistula and occlusion of the common carotid artery. The fistula was corrected by ligature of the internal jugular vein and arteriorrhaphy of the left common carotid artery with a bovine pericardium patch.

A embolia arterial periférica originada de tumores malignos é considerada uma manifestação rara da doença neoplásica, podendo se originar de vários sítios, incluindo coração, aorta e veias pulmonares, sendo estas últimas, fontes massivas de embolia por trombo ou tumores com erosão para seu lúmen. Apesar de infrequente, a neoplasia pulmonar deve ser considerada como uma fonte de êmbolos para as extremidades, principalmente quando há invasão neoplásica para as veias pulmonares. Apresentamos o caso de um paciente do sexo masculino submetido à pneumectomia por neoplasia pulmonar, que evoluiu com oclusão arterial aguda de membros inferiores por êmbolo tumoral " a cavaleiro".

Peripheral arterial embolism (PAE) caused by malignant tumors is a rare manifestation of cancer. PAE may originate from several sites, including heart, aorta, and pulmonary veins. Such veins are a major source of thrombotic embolism or tumors with vascular erosion. Although uncommon, lung cancer should be regarded as a source of emboli in the extremities, especially when there is neoplastic invasion of the pulmonary veins. We report on a case of a male patient who underwent pneumonectomy for lung cancer who developed acute arterial occlusion of the lower extremities caused by saddle tumor embolus.

The objective of this study was to identify possible predisposing factors for candiduria in intensive care unit (ICU) patients from Hospital das Clínicas, Universidade Federal de Goiás, Goiânia, Brazil, during one year. Urine samples from 153 ICU patients were obtained by catheterization on admission day and every seven days. Data such as sex, age, antifungal therapy, and variables as antibiotics, underlying diseases or comorbid conditions and stay in the hospital, were collected from patients who had at least one urine culture that yielded > 10³ yeast colonies/ml. Candiduria was recovered in 68 patients and the commonest predisposing factors were antibiotic therapy (100%) and indwelling urinary catheter (92.6%). The percentage of Candida spp. isolation increased during the extended periods in which patients remained in the ICU. C. albicans was isolated in 69.1%, and the other species non-albicans as C. glabrata, C. kefyr, C. parapsilosis, C. famata, C. guilliermondii, C. krusei, and C. tropicalis were isolated in lower percentage. The high frequency of candiduria and the possible predisposing factors found in ICU patients show that candiduria surveillance should be performed to help reducing nosocomial infections.
