[Step-by-Step tutorial of bedside percutaneous dilatational tracheostomy].

Bedside percutaneous dilatational tracheostomy has become one of the most commonly used interventions in ICU medicine. Different techniques have been developed, but guidance of percutaneous dilatational tracheostomy by video bronchoscope has been suggested to be clinically reasonable for direct visualization. The current Step-by-Step tutorial gives a detailed instruction of the procedure with visualization of every single step offering tips and pitfalls of the procedure.

Do patients return to sports and work after total shoulder replacement surgery?

Background: Studies evaluating the return to sports and work after shoulder arthroplasty are rare, and there are no studies evaluating return to work after total shoulder arthroplasty (TSA).

Hypothesis: Patients undergoing TSA will be able to return to their preoperative sports levels and occupations.

Study Design: Case series; Level of evidence, 4.

Evaluation of thyroid nodules--combined use of (99m)Tc-methylisobutylnitrile scintigraphy and aspiration cytology to assess risk of malignancy and stratify patients for surgical or nonsurgical therapy--a retrospective cohort study.

Objective: Thyroid nodules are a common clinical problem, and differentiation between benign and malignant nodules is essential. The aim of this study was to evaluate an approach for cold thyroid nodules including (99m)Tc-methylisobutylnitrile (MIBI) scintigraphy to assess risk of malignancy and stratify patients for therapy.

Design: Retrospective cohort study; 391 patients with at least one cold thyroid nodule were consecutively admitted (between 1 January 2004 and 31 December 2006) and recommended for surgical or nonsurgical therapy.
