Recently, ultrasound has emerged as a potentially useful tool to assist PDT and reduce procedure-related complications. An open-label, parallel, non-inferiority randomized controlled trial was conducted comparing an ultrasound-guided PDT with a bronchoscopy-guided PDT in mechanically ventilated critically ill patients. The primary outcome was procedure failure, defined as a composite end-point of conversion to a surgical tracheostomy, unplanned associated use of bronchoscopy or ultrasound during PDT, or the occurrence of a major complication. A total of 4965 patients were assessed for eligibility. Of these, 171 patients were eligible and 118 underwent the procedure, with 60 patients randomly assigned to the ultrasound group and 58 patients to the bronchoscopy group. Procedure failure occurred in one (1.7 %) patient in the ultrasound group and one (1.7 %) patient i...

Proper surgical treatment depends upon accurate histological findings, especially in the case of malignant lesions. As such, knowledge of correct cytological findings prior to surgery is important for therapeutic planning. This is not easily established since it is usually based only on the patients' clinical history and imaging exams To evaluate results obtained from fine needle aspiration biopsy (FNAB), comparing them to the histological findings of the respective surgical specimens and analyzing the sensitivity, specificity and accuracy of this method in relation to the diagnosis of malignancy or benignancy. Retrospective study with the medical records of 73 patients who had salivary gland neoplasms and were submitted to FNAB and surgical treatment. Data disclosed that values of sensitivity were 87.9 % and specificity 85.7 % for diagnosis of benign tumors. For malignant tumors 42.5 % of sensitivity ...
