Implementation of a novel point-of-care ultrasound billing and reimbursement program: fiscal impact.
The aim of this study was to determine the fiscal impact of implementation of a novel emergency department (ED) point-of-care (POC) ultrasound billing and reimbursement program. ⋯ Within 1 year of inception, our novel POC ultrasound billing and reimbursement program generated significant revenue through ultrasound billing.

Heatstroke is one of the most common clinical emergencies. Heatstroke that occurred in a dry-heat environment such as desert is usually more seriously effective and often leads to death. However, the report of the pathophysiologic mechanisms about heatstroke in dry-heat environment of desert has not been seen. ⋯ We have successfully established the rat heatstroke model of dry-heat environment of desert. We have identified heatstroke rats that presented changing characteristics on physiological indicators and varying degrees of organ damage, which are aggravated by the evolution of heatstroke in dry-heat environment of desert. We have preliminarily discussed the mechanism of heatstroke in dry-heat environment of desert.

Nebulized particles must have diameters between 1 to 5 μm (optimal particle size range [OPSR]) to be deposited in the lower respiratory tract. The purpose of this study is to determine factors that affect the particle size distributions of nebulized albuterol. ⋯ Single-use disposable nebulizers do not degrade with use, but their performance is highly dependent on gas flow rates. At the flow rate achieved by the home pump, the semipermanent nebulizer performs better than the SUD nebulizer.

Pericardial effusion is commonly detected in patients with severe hypothyroidism and is typically mild; rarely, it may lead to cardiac tamponade. Cardiac tamponade with myxedema coma as initial presenting feature of previously unrecognized hypothyroidism is rare. This case highlights that previously undiagnosed hypothyroidism can manifest as myxedema coma with shock due to pericardial tamponade particularly in winters because a cold environment can precipitate myxedema. ⋯ Cardiac tamponade and myxedema coma as presenting features of previously unrecognized primary hypothyroidism are extremely rare. Urgent bedside echocardiography with pericardiocentesis along with thyroxine therapy is the treatment of choice. It is important to include hypothyroidism as the differential diagnosis in patients with cardiac tamponade and altered level of consciousness especially in winter months.

Gluteraldehyde is an effective and widely used disinfectant. Despite the large volume of endoscopic procedures carried out, gluteraldehyde-induced colitis is rare. It typically presents with acute onset of lower abdominal pain, fever, and bloody stool, within hours to up to 2 days of endoscopy. Even though a self-limiting condition, it is important for front line clinicians to be aware of this entity as procedure related complications is of major concern to patients and healthcare providers.
