Whenever a patient presents with chest pain, shortness of breath, dizziness, fainting, or irregular heartbeats, an electrocardiogram (ECG) will be ordered to determine any heart abnormalities. Many of these abnormalities may include coronary artery disease, unstable angina, acute myocardial infarction, arrhythmias, and cardiomyopathies, to name a few. Coronary artery disease is the buildup of plaque in the arteries surrounding the heart, restricting blood flow and resulting in chest pain, which is also known as unstable angina. A myocardial infarction (heart attack) is whenever this plaque builds up so much that it completely blocks the vessels, causing the heart to lose blood supply and killing heart tissue. Some symptoms can include: chest pain, shortness of breath, dizziness, nausea, vomiting, and heartburn. Arrhythmias are abnormally fast, slow or irregular heart beats. Cardiomyopathies are conditions affecting heart tissue, causing the tissue to be dilated, hypertrophic, or restrictive. Symptoms include shortness of breath, fatigue, swelling of lower extremities, coughing when lying down, dizziness, chest pain, and arrhythmias. Continue reading
As a physician, a patient comes to you presenting with bone pain, weight loss, nausea and vomiting. Ordered tests come back abnormal: the complete blood count (CBC) shows low cell counts with abnormal cells, calcium, urea and creatinine levels are elevated, and the X-ray demonstrates bone lesions. All these signs point towards multiple myeloma, a type of cancer in which plasma cells form multiple masses in the bone marrow. Therefore, a serum protein electrophoresis is ordered to confirm your suspicion. Continue reading
Toxoplasma gondii is the causative agent of the disease known as toxoplasmosis. The parasite was first discovered by Charles Nicolle and Louis Manceaux in 1908 while working with the rodent Ctenodactylus gundi. They initially named the parasite Leishmania gondii thinking that it belonged to the Leishmania genus. However, once they realized they discovered a new organism, they named it Toxoplasma gondii, from the Greek toxo, meaning arc or bow, and plasma, meaning something that is shaped or molded. The parasite’s definitive host is the cat in which T. gondii can sexually reproduce.
Giardiasis, also known as “beaver fever”, is caused by an infection with the gastrointestinal parasite, Giardia lamblia. This parasite was first discovered by the “Father of the Microscope”, Antoine van Leeuwenhoek, and later described by and named after Alfred Mathieu Giard and Vilém Dušan Lambl.
