In these modern times, it can sometimes be difficult to recognize the significant impact that many medications have had in eliminating fatal conditions and diseases. For any woman who has been pregnant and has the Rh-Negative blood group, this medication is Rh Immune Globulin (or RhIg for short).
In this blog series, clinical laboratory testing will be shown in a case-study format along with clinical presentations of patients.
Clinical Perspectives: Electrocardiogram in the diagnosis of heart conditions
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 build up 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) occurs 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 of cardiomyopathies include: shortness of breath, fatigue, swelling of lower extremities, coughing when lying down, dizziness, chest pain, and arrhythmias. Continue reading
Clinical Perspectives: Multiple Myeloma and Serum Protein Electrophoresis
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
