Acute cytomegalovirus infection associated with pulmonary embolism treated successfully with rivaroxaban: case report.

Severe life-threatening thromboembolism may be caused exclusively by the presence of an acute CMV infection or due to the association of this agent and other thrombogenic factors. We report a case of an immunocompetent young female patient who presented a pulmonary embolism associated with acute CMV infection. The patient did not have any other apparent cause of thrombosis. She was successfully treated with rivaroxaban for 6 months without further episodes. To the best of our knowledge, this is the first report of a pulmonary embolism associated with CMV treated with a direct oral anticoagulant. The current case report calls attention to the importance of signs and symptoms of thromboembolism among patients with CMV. Direct oral anticoagulants can potentially bring the same benefits to treat pulmonary embolism associated with CMV as those observed in patients not infected.

Crohn's disease versus Yersinia enterocolitica infection - case report - a difficult differential diagnosis / Doença de Crohn's × Yersinia enterocolitica - um difícil diagnóstico diferencial - relato de caso

ABSTRACT The aim of this report is to present an unusual case of Crohn's disease affecting the terminal ileum; whose principal differential diagnosis was Yersinia enterolocolitica infection, as the histological features of the resected ileum was common to both diseases. We also describe how the infectious etiology was discarded and the implications for the patient follow-up.

RESUMO O objetivo desse relato é analisar um caso incomum de doença de Crohn, cujo diagnóstico diferencial, com possível infecção por Yersinia enterocilítica, foi dificultado pela presença de alterações histológicas das duas doenças. Descrevemos como foi realizada a exclusão de causas infecciosas e as implicações no acompanhamento do paciente.

A non-living, effective model for microvascular training

Abstract Purpose: To introduce a nonliving microvascular training model based on vessels diameter and feasibility. Methods: We dissected ten oxen tongues, and divided the pedicles into three-thirds: proximal, middle and distal. We measured the external vessels diameter in all regions. We performed a descriptive statistical analysis. Three students (two beginner level and one intermediate level) performed this training. We evaluated the confidence, according Likert scale. Results: We dissected all oxen tongues, each tongue showed two parallel pedicles. Each pedicle was located at 1.5 - 2.0 cm from the midline. Proximal median artery and vein diameter were 3.9 ± 0.7, and 5.04 ± 1.44mm, respectively. In the middle third, the mean artery diameter was 3.3 ± 0.4mm, and the vein diameter was 3.5 ± 0.9mm. The distal third showed a mean artery diameter of 2.0 ± 0.42mm, and a vein diameter of 2.4 ± 0.82mm. The students performed ten anastomoses. This study showed a higher confidence level (CL) (p=0.03) than the pre training CL assessment. Conclusion: This study suggested a feasible non-animal model for microsurgical training process for beginners and intermediate trainees.
