Amiodarone-induced Loculated Pleural Effusion Without Pulmonary Parenchymal Involvement: a Case Report and Literature Review

Amiodarone is an extremely effective antiarrhythmic drug that is known to cause many adverse effects such as pulmonary, thyroid, and liver toxicities. Of these, pulmonary toxicity is most serious. Pulmonary toxicity can present as interstitial pneumonitis, organizing pneumonia, pulmonary nodules and masses, and very rarely pleural effusions. We present a case of a 73-year-old male who presented with progressive exertional dyspnea, nonproductive cough, generalized fatigue, and weakness. He was found to have multiorgan toxicity secondary to long-term treatment with high doses of amiodarone. This case illustrates that amiodarone may cause toxicity involving multiple organs simultaneously in patients receiving long-term therapy and represents the first reported case of amiodarone-induced loculated pleural effusion without associated lung parenchymal involvement

Value of Neutrophil to Lymphocyte Ratio as a Predictor of Mortality in Patients Undergoing Aortic Valve Replacement

Background: Neutrophil to lymphocyte ratio (NLR) has been studied as a measure of inflammation and as a prognosticating factor in various medical conditions including neoplastic, inflammatory and cardiovascular. The prognostic role of NLR in predicting mortality in patients with aortic stenosis undergoing surgical aortic valve replacement (AVR) has not been studied. The aim of our study is to explore the utility of NLR as a predictor of both, short and long-term mortality, in patients undergoing surgical AVR. Methods: Consecutive patients with aortic stenosis admitted for AVR to our institution were evaluated for study inclusion. Of the 335 patients admitted from January 2007 to September 2011, 234 met study inclusion criteria. Patients were divided into two groups depending on their initial preoperative NLR level with a cutoff value of 3. Three-year vital status was accessed with electronic medical records and Social Security Death Index. Survival analysis, stratified by NLR, was used to evaluate the predictive value of preoperative NLR levels. Results: Patients with NLR \u3e/=3, when compared to those with NLR /=3 had 4.77 fold increase in 3-year mortality (1.48-15.32, P=0.0090). Conclusions: NLR is an independent predictor of short-term and long-term mortality in patients with aortic stenosis undergoing AVR surgery, especially those with NLR \u3e/=3. We strongly suggest the use of NLR as a tool to risk stratify patients with aortic stenosis undergoing AVR surgery

Amiodarone Induced Myxedema Coma: Two Case Reports and Literature Review

Amiodarone is a benzofuran derivative that contains 37% iodine by weight and is structurally similar to the thyroid hormones. Amiodarone has a complex effect on the thyroid gland, ranging from abnormalities of thyroid function tests to overt thyroid dysfunction, with either thyrotoxicosis or hypothyroidism. Myxedema coma secondary to amiodarone use has been rarely reported in the literature. Our two case reports are an add on to the literature, and illustrate that amiodarone is an important cause of thyroid dysfunction including hypothyroidism and myxedema coma. Hence, healthcare providers should have a high index of suspicion for these conditions while treating patients who are taking amiodarone therapy as early recognition and management are essential to optimize outcomes

Losartan-induced ischemic hepatocellular hepatotoxicity: A case report and literature review

With the increasing use of various medications and supplements nowadays, the incidence of abnormal liver function tests and frank hepatic injury is has been increasing. Medications are now considered one of the most common causes of acute hepatic failure in the United States. Losartan was the first angiotensin 1 (AT1) receptor blocker approved by FDA for the treatment of arterial hypertension. It is a well-tolerated medication with few significant adverse effects. However, losartan-related hepatotoxicity has been reported rarely. We report a case of acute hepatic injury in an adult patient treated with losartan as a monotherapy for arterial hypertension

Ogilvie’s Syndrome following Cardioversion for Atrial Fibrillation

Acute colonic pseudoobstruction, also known as Ogilvie’s syndrome, is characterized by distension of the colon in the absence of a mechanical obstruction as evident by abdominal radiography. This syndrome is usually treated conservatively; however, medical or surgical therapies can be employed in refractory cases. Ogilvie’s syndrome has been reported following cardiac events, such as myocardial infarction, heart failure, and cardiac bypass surgeries. We report the first case of Ogilvie’s syndrome following synchronized electric cardioversion for atrial fibrillation
