It has been previously demonstrated that the risk for the development of knee osteoarthritis is increased after both meniscus tear and meniscectomy. However, it is still unclear whether this is due to the meniscus tear per se, the surgery, or whether the development of knee osteoarthritis is completely independent of the two. Accordingly, the aim of the study is to investig...

A substantial body of evidence implicates the endogenous opioid system, and the mu opioid receptor (MOR) in particular, in the reinforcing effects of drugs of abuse, including nicotine. A single nucleotide polymorphism (SNP) in the mu opioid receptor gene (OPRM1 Asp40) is associated with the ability to quit smoking, as well as nicotine reward and withdrawal symptoms. Howeve...

Standard treatment for early stage bladder cancer is chemotherapy with methotrexate (M), vinblastine (V), adriamycin (A), and cisplatin (C) followed by surgical removal of any remaining cancer and the bladder with the intent of cure. The MV chemotherapy is usually given every 14 days with the AC given along each 28 days. This study looks at giving the same drugs at the sa...

Background: distal radial buckle fractures are common injuries in children. the ideal immobilization technique is controversial.

Furosemide in Early Acute Kidney Injury

Added: 22:19 EDT 26 Aug 2014

Acute renal failure, now referred to as acute kidney injury, is common in intensive care unit patients, contributes to high morbidity and mortality, and has no proven interventions with benefit once established. In addition to supportive care, these patients frequently receive diuretic therapy, most commonly furosemide. Prior trials showed no impact of furosemide on clinic...

Facial lacerations are a commonly encountered problem in the emergency department. Despite this, few original articles have been written concerning the management of lacerations of the lip which communicate with the oral cavity. Specifically, no study has been able to definitively show whether the use of antibiotics for these wounds decreases the infection rate. These cuta...

Chocolate consumption has long been associated with enjoyment and pleasure. Popular claims confer on chocolate the properties of being a stimulant, relaxant, euphoriant and antidepressant. These possible pharmacological actions might be related to various biogenic amines, such as serotonin, dopamine, tyramine, histamine, phenylethylamine and cannabinoid-like substances. Mos...

The purpose of this research is to understand the properties of mucus in persons with COPD, specifically Chronic Bronchitis. The investigators hypothesize that those with Chronic Bronchitis have dehydrated mucus, and thus have a harder time coughing it out of their lungs. This leads to a greater vulnerability for lung infection, inflammation and airflow obstruction. Ulti...

The prevalence of cellulitis in society is very high, as much as 3% of visits to Emergency Departments are for the treatment of this disease. The treatment of cellulitis varies depending on the severity. Low severity cases are treated with pain control and antibiotics by mouth and high severity are treated with antibiotics intravenously and pain control. The investigator's ...

Systolic function is a substantial determinant of overall hemodynamics and organ function. Therefore assessment of left ventricular systolic function (LVF) has been of central interest in Echocardiography. Ejection fraction (EF) measurement has been the gold standard echo-derived measure to describe LVF. However, EF is a blood pool derived and therefore load dependent meas...

The purpose of this randomized clinical trial is to determine whether haloperidol is superior to olanzapine for the treatment of ICU acquired delirium. The hypothesis is that haloperidol is in fact superior to olanzapine in treating ICU acquired delirium and sustaining delirium free time.
