They can cause teeth staining and dental hypoplasia in developing children, therefore should be avoided in children under 12 years and breast feeding mothers. Minocycline has the broadest spectrum of activity. Tetracyclines are used in the management of chlamydia, Lyme disease, brucella and Q-fever. They can cause teeth staining and dental hypoplasia in developing children, therefore should be avoided in children under 12 years and breast feeding mothers. Minocycline has the broadest spectrum of activity. A normal JVP is about 7 cm from the sternal angle. When do you expect a JVP to rise more than 10cm with a large ‘a” wave? Explanation: The sternal angle is about 5cm above the left atrium when the patient is lying at 45˚. The normal central venous pressure (CVP) is 7cm and therefore the jugular vein is normally just visible.A large ‘a’ wave (corresponding with atrial systole) occurs when the right atrial pressure is raised, e.g.tricuspid stenosis, pulmonary hypertension, pulmonary stenosis and mitral stenosis.There is no ‘a’ wave in atrial fibrillation because there is no atrial systole.

Chest X-ray is an important diagnostic tool for respiratory as well as cardiac diseases. Which of the following are accurate for left atrial enlargement due to combined MS & MR? Left atrial dilatation results in prominence of the left atrial appendage, creating the appearance of a straight left heart border, a double cardiac shadow to the right of the sternum, and widening of the angle of the carina (bifurcation of the trachea) as the left main bronchus is pushed upwards.
