Adaptations to this technique include transection rather than lateral retraction of the strap muscles (the Sofferman technique). [1]

Breast Abscess
Breast Abscess samer kareem 5,376 Views • 2 years ago

Breast abscesses are often linked to mastitis – a condition that causes breast pain and swelling (inflammation), and usually affects women who are breastfeeding. Infections can occur during breastfeeding if bacteria enter your breast tissue, or if the milk ducts (tiny tubes) become blocked. This can cause mastitis which, if not treated, can result in an abscess forming. Women who aren't breastfeeding can also develop mastitis if bacteria enter the milk ducts through a sore or cracked nipple, or a nipple piercing.

Understanding MRIs
Understanding MRIs samer kareem 21,320 Views • 2 years ago

Magnetic resonance imaging (MRI) can be an important tool in the diagnosis of multiple sclerosis (MS). MRI can also be used to monitor the progression of the disease in people living with MS. How does it work? MRI uses very strong magnets, radio signals, and computer software to take 3-dimensional pictures of the inside of the body. Will I need contrast material? Maybe. Contrast material is a substance that temporarily changes the way imaging tools interact with the body. They are often used to visualize certain types of MS disease activity on the MRI. If your doctor thinks your scan requires this contrast material, you may get an injection before you get in the MRI machine. How long will it take? The time may vary based on the type of MRI. Be sure to discuss with your doctor in advance so he or she can provide you with exact timing. But don’t worry, you won’t have to stay still the whole time. The technician will let you know when they’re starting a new image.
