Objective: To expand the adverse events associated with metronidazole to include nonconvulsive status epilepticus (NCSE). Design: Observational single case report of a rare association. Setting: Hospitalized lung transplant recipient treated with metronidazole for prevention of infection. Patient: A 56-year-old man with systemic symptoms, peripheral neuropathy, generalized seizure, and a subsequent acute deterioration of mental status due to NCSE. Interventions: Administration of midazolam was successful in terminating status epilepticus. Main Outcome Measures: Abrupt termination of NCSE was evident on continuous bedside electroencephalogam associated with clinical resolution of mental status. Results: Recovery occurred from NCSE eventually deteriorating to a fatal outcome. Conclusions: Metronidazole may be associated with successfully treated NCSE.

Behçet' s disease is an autoimmune, multifactorial, systemic condition with several clinical manifestations, including vascular disorders. An aortic aneurysm with vertebral erosion is rare in association with this pathology and there are only four case reports listed on the PubMed database. This article reports the case of a female patient with a long-standing diagnosis of Behçet' s Disease who developed a saccular infrarenal abdominal aortic aneurysm with lumbar vertebral erosion. Her surgical treatment consisted of endovascular repair with a monoiliac endoprosthesis and a femorofemoral crossover bypass, because of limitations imposed by the anatomy of the aortic bifurcation. This paper discusses the rarity of this presentation of the disease and treatment outcomes and offers a brief review of the relevant literature.Keywords: Behçet' s Disease; aneurysm; spinal column; vertebral lesions. ResumoA doença de Behçet é uma doença sistêmica, multifatorial e autoimune com diversas manifestações clínicas, entre elas o acometimento vascular. Aneurisma de aorta associado a erosão de vértebra lombar é condição rara na literatura, existindo apenas quatro relatos de caso nas bases de dados da PubMed. O presente artigo relata o caso de paciente do sexo feminino com diagnóstico de Doença de Behçet de longa data e aneurisma sacular de aorta abdominal infrarrenal com erosão de vértebra lombar. O caso foi tratado por meio de técnica endovascular com colocação de endoprótese monoilíaca e enxerto fêmoro-femoral cruzado, devido a limitações anatômicas da bifurcação aórtica. O artigo aborda a raridade desse tipo de apresentação da doença e o desfecho do tratamento e apresenta revisão da literatura sobre esse tema.Palavras-chave: Doença de Behçet; aneurisma; coluna vertebral; lesões de coluna vertebral.

ObjectiveTo compare duplex ultrasound and computed tomography (CT) angiography in terms of their performance in detecting endoleaks, as well as in determining the diameter of the aneurysm sac, in the postoperative follow-up of endovascular abdominal aortic aneurysm repair.Materials and MethodsThis was a prospective study involving 30 patients who had undergone endovascular repair of infrarenal aortoiliac aneurysms. Duplex ultrasound and CT angiography were performed simultaneously by independent radiologists. Measurements of the aneurysm sac diameter were assessed, and the presence or absence of endoleaks was determined.ResultsThe average diameter of the aneurysm sac, as determined by duplex ultrasound and CT angiography was 6.09 ± 1.95 and 6.27 ± 2.16 cm, respectively. Pearson's correlation coefficient showing a statistically significant correlation (R = 0.88; p < 0.01). Comparing the duplex ultrasound and CT angiography results regarding the detection of endoleaks, we found that the former had a negative predictive value of 92.59% and a specificity of 96.15%.ConclusionOur results show that there is little variation between the two methods evaluated, and that the choice between the two would have no significant effect on clinical management. Duplex ultrasound could replace CT angiography in the postoperative follow-up of endovascular aneurysm repair of the infrarenal aorta, because it is a low-cost procedure without the potential clinical complications related to the use of iodinated contrast and exposure to radiation.

Resumo A esclerose tuberosa é uma doença genética de transmissão autossômica dominante. Caracteriza-se, na sua apresentação clássica, por epilepsia, deficiência mental e adenomas sebáceos. Aneurismas de aorta podem acometer desde crianças com poucos meses de vida até adultos jovens portadores de esclerose tuberosa. Apresentamos o caso de uma paciente jovem com diagnóstico de aneurisma sacular de aorta torácica e esclerose tuberosa tratada com sucesso por via endovascular.
