Patients that are mechanically ventilated in ICUs are constantly exposed to different pathogens, which present multiantibiotic resistance. Among these microorganisms, is MRSA (Meticillin-Resistant Staphylococcus aureus) considered to be a therapeutic challenge due to its resistance to β-lactam antibiotics. Therefore, this study proposed to identify species of Staphylococcus spp. isolated from mechanically ventilated patients in ICU, the gene mecA detection and the genes of the enterotoxins A (sea), B (seb), C (sec-1) and D (sed) in samples of S. aureus, as well as the phenotypic resistance determination to oxacillin using the disc-diffusion method with discs of oxacillin and cefoxitin. The samples collection occurred during in a period of 19 months, obtaining samples from 232 patients. A percentage of 39% (70) of Gram-positive cocci were found; which 82,8% (58) were identified as Staphylococcus spp,. among these, 75,8% (44) corresponded to S. aureus species and 47,7% were identified as MRSA. It was found resistance to both drugs in 31,8% of the S. aureus samples, 16 (36,3%) had the gene sea and 11 (25%) had the sec-1 gene. Among the coagulase-negative staphylococci obtained, the species most found was S. epidermidis, corresponding to 43% (6). The results revealed that one of the most important etiologic agents of VAP amid the Gram-positive cocci is the species S. aureus, with special attention to MRSA. The presence of enterotoxins genes in S. aureus did not showed determinant role in VAP, but the presence of these superantigens can contribute worsening the patient’s prognosis, since they are associated with intense inflammatory response

Introduction: The mandibular injuries account for about 20% to 50% of cases of facial fractures. Some consider the jaw the second most commonly fractured bone of the skull, and is the only mobile bone of the facial framework, which results in decreased stability compared to the trauma. When one takes into account the degree of airway obstruction in patients with facial fractures, the problem becomes much more serious since it is one of the most troubling complications of trauma. Objective: the relevance of the topic is aimed to report a case of a patient victim of mandibular fracture associated with trauma to the trachea. Case report: Case report: Patient 24 years old patient with tracheal trauma concomitant mandibular fracture surgically treated in conjunction with the thoracic surgeon. After 5 months postoperatively, the patient is in good condition general, no complaints. Final comments: This form is observed that the key to proper treatment of tracheal trauma associated with facial fractures is the knowledge of the type of injury, and an accurate diagnosis multidisciplinary.

Objetivamos testar um novo modelo de endoprótese traqueal autoexpansível para que esse possa ser futuramente disponibilizado para o uso clínico. As endopróteses de nitinol revestidas de poliuretano foram alocadas no terço médio da traqueia de 25 coelhos da raça Nova Zelândia sob laringoscopia direta. Após um período de observação médio de 26 dias, avaliou-se a migração da prótese, grau de dilatação, incorporação, aderência, formação de tecido de granulação, presença de infiltrado inflamatório, envolvimento parietal e revestimento epitelial. Os resultados demonstraram completa expansibilidade radial, pouca aderência à mucosa traqueal e baixa incorporação tecidual, assim como alta taxas de formação de granulomas e de migração. Esse novo modelo demonstrou ser biocompatível e teve comportamento semelhante ao de outras próteses disponíveis no mercado.

[ES] Como resultado del dinamismo inherente al entorno competitivo, las empresas actuales necesitan ampliar de manera continua su base de conocimientos. Una vía para ello es organizar el trabajo en equipos y tratar de que sus integrantes creen, transfieran e integren (CTI) su conocimiento. Sin embargo, no todos los equipos logran ese objetivo. Por ello, el propósito de este trabajo es identificar qué factores potencian o dificultan la CTI de conocimiento en equipos de trabajo y qué mecanismos tienen las empresas para favorecer la presencia de tales factores. Sobre la base de un estudio empírico realizado con una muestra de 363 individuos de doce grandes empresas, en su mayoría multinacionales, establecemos cuáles son tales factores y mecanismos, exponiendo su importancia relativa.
