Rhabdomyolysis is a well-known clinical syndrome of muscle injury associated with myoglobinuria, electrolyte abnormalities, and often acute kidney injury (AKI). The pathophysiology involves injury to the myocyte membrane and/or altered energy production that results in increased intracellular calcium concentrations and initiation of destructive processes. Myoglobin has been identified as the primary muscle constituent contributing to renal damage in rhabdomyolysis. ⋯ There is little evidence other than from animal studies, retrospective observational studies, and case series to support the routine use of bicarbonate-containing fluids, mannitol, and loop diuretics. Hyperkalemia and compartment syndrome are additional complications of rhabdomyolysis that must be treated effectively. A definite need exists for well-designed prospective studies to determine the optimal management of rhabdomyolysis.

Ipsilateral Opposite-Side Aspiration in Resistant Pneumothorax After CT Image Guided Lung Biopsy: Complementary Role After Simple Needle Aspiration.
The goal of this study was to evaluate the efficacy of ipsilateral opposite-side aspiration, a new method to overcome resistant pneumothorax after failure of a simple aspiration. The patient position is reversed (from prone to supine or vice versa) and the aspiration repeated. ⋯ Immediate, simple, percutaneous aspiration of iatrogenic pneumothorax was successful in 74% of patients needing treatment. Our proposed new method of ipsilateral opposite-side aspiration offers a solution for patients who remain with resistant pneumothorax after simple aspiration.

Impact of age and comorbidity on cause and outcome in community-acquired pneumonia.
Prolonged life expectancy has currently increased the proportion of the very elderly among patients with community-acquired pneumonia (CAP). The aim of this study was to determine the influence of age and comorbidity on microbial patterns in patients over 65 years of age with CAP. ⋯ Age does not influence microbial cause itself, whereas comorbidities are associated with specific causes such as H. influenzae and potential MDR pathogens. Mortality in the elderly is mainly driven by the presence of comorbidities and potential MDR pathogens.

Comparative Study
A new instrument to assess physician skill at thoracic ultrasound, including pleural effusion markup.
To reduce complications and increase success, thoracic ultrasound is recommended to guide all chest drainage procedures. Despite this, no tools currently exist to assess proceduralist training or competence. This study aims to validate an instrument to assess physician skill at performing thoracic ultrasound, including effusion markup, and examine its validity. ⋯ Procedural training on mannequins prior to unsupervised performance on patients is rapidly becoming the standard in medical education. This study has validated the UGSTAT, which can now be used to determine the adequacy of thoracic ultrasound training prior to clinical practice. It is likely that its role could be extended to live patients, providing a way to document ongoing procedural competence.

COPD is a common comorbidity in heart failure. The efficacy of implantable cardioverter-defibrillator (ICD) therapy has not been determined in patients with heart failure and COPD. ⋯ Patients with COPD have a higher incidence of ICD shocks than those without COPD and appear to benefit from ICD therapy.
