Secondary Amenorrhea samer kareem 2,717 Views • 2 years ago

Absence of a woman's monthly menstrual period is called amenorrhea. Secondary amenorrhea is when a woman who has been having normal menstrual cycles stops getting her periods for 6 months or longer. Causes Secondary amenorrhea can occur due to natural changes in the body. For example, the most common cause of secondary amenorrhea is pregnancy. Breastfeeding and menopause are also common, but natural, causes. Women who take birth control pills or who receive hormone shots such as Depo-Provera may not have any monthly bleeding. When they stop taking these hormones, their periods may not return for more than 6 months. You are more likely to have absent periods if you: Are obese Exercise too much and for long periods of time Have very low body fat (less than 15 to 17%) Have severe anxiety or emotional distress Lose a lot of weight suddenly (for example, from strict or extreme diets or after gastric bypass surgery) Other causes include: Brain (pituitary) tumors Drugs for cancer treatment Drugs to treat schizophrenia or psychosis Overactive thyroid gland Polycystic ovarian syndrome Reduced function of the ovaries

ACE INHIBITORS MECHANISM OF ACTION samer kareem 3,149 Views • 2 years ago

ACE Inhibitor Mechanisms. Angiotensin converting enzyme (ACE) inhibitors are agents used to relax blood vessels and lower blood pressure.

Hiatal Hernia: Explanation of Chest X-Ray Findings
Hiatal Hernia: Explanation of Chest X-Ray Findings DrPhil 128 Views • 2 years ago

The typical radiograph is of a well-defined, rounded, retrocardiac opacity with an air-fluid level. In this image, the radiolucent gas is highlighted in blue, while the gastric contents are highlighted in the green. In many cases of hiatal hernia, there will not be an air bubble below the left hemidiaphragm. This is a relatively expected finding considering that the stomach is no longer in its usual position. The anatomical position of the herniated organ can be further elucidated on the lateral radiograph. Here we can see that the stomach is in the middle mediastinum posterior to the heart and above the diaphragm. Hiatal hernias can look similar to a retrocardiac lung abscess or another cavitary lesion, but it will change in size and shape between radiographs. Large hernias can shift the mediastinum to the right and result in a widening of the carinal angle. They can even give the appearance of cardiomegaly. In this radiograph, the cardiac silhouette is distinctly visible within the confines of the hiatal hernia. To review, a hiatal hernia on an AP chest radiograph typically appears as a round retrocardiac opacity with an air-fluid level.
