Use of mobile learning applications as an innovative method for the teaching of biochemistry.

Background: Traditional teaching methods of biochemistry provide effective tools for knowledge transmission, but are considered less engaging with students. Smartphone applications may provide suitable alternatives to compensate for the shortcomings of traditional teaching methods.

Purpose: This study aimed to assess the effectiveness of smartphone applications as a complementary method for learning biochemistry.

Postoperative takotsubo cardiomyopathy: an illustration of the electrocardiographic features that raise suspicion for takotsubo.

Takotsubo cardiomyopathy is an increasingly recognized clinical disorder mimicking acute coronary syndrome. It is usually preceded by physical or emotional stress and recovery of the left ventricular systolic function occurs in most cases within 1-4 weeks. Takotsubo cardiomypathy can masquerade as ST-segment elevation myocardial infarction when chest pain, ST-segment elevation, and high cardiac biomarkers coexist.

Sustainability and effectiveness of a quality improvement project to improve handoffs to night float residents in an internal medicine residency program.

Background: Handoff is the process in which patient care is transitioned from one provider to another. In teaching hospitals, handoffs are frequent, and resident duty hour restrictions have increased the use of night float staff. To date, few studies have focused on long-term sustainability and effectiveness of a handoff quality improvement project.

Unprotected left main coronary stenting as alternative therapy to coronary bypass surgery in high surgical risk acute coronary syndrome patients.

Acute coronary syndrome has a high mortality rate that dramatically increases in the presence of left main coronary artery (LMCA) disease. Over the past decades, coronary artery bypass graft (CABG) surgery has been commonly accepted as the standard of care for patients with LMCA stenosis and is still considered the first-line treatment in current practice guidelines. Percutaneous coronary intervention (PCI) of protected and unprotected LMCA has gained popularity and is increasingly utilized with comparable outcomes to CABG in randomized controlled trials.

Licorice abuse: time to send a warning message.

Licorice extract has always been recognized as a sweetener and a thirst quencher. Its nutritive value is overrated by many who consume significant amounts and are prone to complications. Glycyrrhetic acid, the active metabolite in licorice, inhibits the enzyme 11-ß-hydroxysteroid dehydrogenase enzyme type 2 with a resultant cortisol-induced mineralocorticoid effect and the tendency towards the elevation of sodium and reduction of potassium levels.

Simultaneous left anterior descending and right coronary stent thrombosis after aspirin withdrawal.

ST-segment elevation myocardial infarction is usually caused by plaque rupture and subsequent thrombosis of a single culprit vessel. In rare occasions, simultaneous thrombosis of 2 coronary arteries occurs, which is usually associated with a worse prognosis. Although surgery provokes hemodynamic stress, leading in some instances to myocardial ischemia due to supply/demand mismatch, other factors may also contribute to postoperative myocardial infarction.

Occult pneumothorax, revisited.

Pneumothorax is a recognized cause of preventable death following chest wall trauma where a simple intervention can be life saving. In cases of trauma patients where cervical spine immobilization is mandatory, supine AP chest radiograph is the most practical initial study. It is however not as sensitive as CT chest for early detection of a pneumothorax.
