Interpretation of Spirometry, Peak Flow, and Provocation Testing for Asthma.

Spirometry plays a crucial role in the diagnosis of asthma. The hallmark spirometry finding of expiratory airflow variability can be demonstrated in several ways including peak airflow and bronchodilator and bronchoprovocation testing. Challenges of overdiagnosis and underdiagnosis underscore the need to consider clinical context while interpreting these tests.

Therapeutic Plasma Exchange in Severe Rhabdomyolysis: A Case-Control Study.

Introduction:  Rhabdomyolysis is a serious condition that can cause acute kidney injury (AKI), compartment syndrome, severe metabolic and electrolyte derangement leading to arrhythmias, and even death. Total plasma exchange (TPE) has been used as a treatment modality to clear myoglobin, but the evidence is limited. In this study, we aim to investigate the use of TPE in critically ill rhabdomyolysis patients.

Dialysis in disaster: Using continuous renal replacement therapy for end-stage renal disease patients, a pilot proof of concept study.

Introduction: Each dialysis session uses approximately 150 to 200 L of water. The winter storm that swept southwest USA saw an unprecedented disruption of water supplies due to which intermittent hemodialysis could not be performed for end-stage renal disease (ESRD) patients. We present 4 cases when continuous renal replacement therapy (CRRT) was utilized to provide urgent hemodialysis in hemodynamically stable, non-critically ill ESRD patients during this time of water supply crisis.
