Dapsone-Induced Methemoglobinemia Presenting Concomitantly With COVID-19 Pneumonia and Pulmonary Embolism: A Case Report.

Acquired methemoglobinemia is a treatable condition that is often clinically subtle and can be missed on routine clinical assessment. We present a 73-year-old male who was evaluated in the emergency department with worsening respiratory symptoms requiring oxygen. He tested COVID-19 positive and had new pulmonary emboli evident on his CT chest.

Diagnosed by Reversibility: Unmasking Propofol-Related Infusion Syndrome in a Critically-Ill Elderly Male.

Propofol-related infusion syndrome (PRIS) is an uncommon complication resulting from prolonged propofol use. Common clinical presentations include metabolic acidosis, cardiac arrhythmias, and renal complications. The mortality rate is high if it is not recognized in time.

Loeys-Dietz Syndrome Complicated by Right Coronary Artery Pseudoaneurysm.

Loeys-Dietz syndrome is a rare autosomal dominant connective tissue disorder notable for rapidly progressive vascular aneurysmal disease and craniofacial defects. Patients are at an increased risk for aneurysm rupture and dissection at younger ages compared to other aneurysmal syndromes. Early surgical intervention is important for prevention of ruptures and/or dissection.

Systematic review of nephrotoxicity of drugs of abuse, 2005-2016.

Background: The United States is faced with an unprecedented epidemic of drug abuse. Every year thousands of Americans visit the emergency departments all over the country with illicit drug related complaints. These drugs have been known to be associated with a range of renal pathologies, from reversible acute kidney injuries to debilitating irreversible conditions like renal infarction.

Femoral Neck Bone Mineral Density in Persons Over 50 Years Performing Shiftwork: An Epidemiological Study.

Objective: Shiftwork has been associated with bone loss due to hormonal fluctuations. Our aim was to assess the femoral neck bone mineral density and content in persons over 50 years performing shiftwork.

Methods: We performed analysis on the femoral neck bone mineral parameters in persons over age 50 years from the National Health and Nutrition Examination Survey cross-sectional data for 2010 to 2011 in regular and shiftworkers.

Predictors of systolic blood pressure in post-menopausal euthyroid women: A study of the NHANES continuous survey data 2007-2012.

There is an increased risk of cardiovascular disease and higher rate of hypertension in post-menopausal (compared to pre-menopausal women). We analysed the cross-sectional National Health and Nutritional Examination and Survey 2007-2012 to look at the factors that affect systolic blood pressure in post-menopausal women. We also performed a linear regression with systolic blood pressure as the dependent variable and age, body mass index, total cholesterol, triglycerides, A1C and serum creatinine as independent variables.

Cardiotonic steroids in adaptation to dietary salt intake.

For many years the concept relating salt to blood pressure (BP) changes has been debated and the concept of natriuretic hormone eliminating excessive sodium by direct inhibition of Na/K-ATPase has raised controversy. However, a recently discovered Na/K-ATPase signaling function has been widely confirmed and provided a novel mechanism to explain the relationship between sodium and blood pressure. Recently, we have demonstrated that activation of this Na/KATPase signaling function regulates sodium reabsorption in renal proximal tubules (RPTs) to correct sodium retention related volume expansion and BP increase.
