Stretch marks typically appear as bands of parallel lines on your skin. These lines are a different color and texture than your normal skin, and they range from purple to bright pink to light gray. When you touch stretch marks with your fingers, you might feel a slight ridge or indentation on your skin. Sometimes, stretch marks feel itchy or sore. These lines commonly appear during or after pregnancy or after a sudden change in your weight. They also tend to occur in adolescents who are rapidly growing.
In short, stretch marks are scars that are permanent once formed. Lower respiratory tract infections are, in people with HIV, the most common cause of hospitalization in an intensive care unit (ICU), according to a 2007 report from University College Hospital (UCH), London. Nearly half of people with HIV admitted to ICUs (48%) had a pulmonary (lung) infection, with Pneumocystis pneumonia (PCP) and bacterial pneumonia being the diagnosis in 80% of them. A 2009 US study reported about 40% of HIV-positive people in intensive care were admitted with respiratory failure, including pneumonia and other lung conditions such as emphysema.
Improvement in stretch marks with laser therapy is accomplished by wounding the scarred skin and hoping that the newly healed skin will have a more normal, cosmetically acceptable appearance. Medical reports of Nd:YAG laser, radiofrequency devices, and fractional photothermolysis have shown some degree of improvement in stretch mark appearance but not resolution. The earlier the stretch mark is treated, generally the better the result. Red immature stretch marks are more amenable to treatment than those that have matured to a silvery white. This is because the reddish stretch marks are still healing, and the healing can be modified by intervention. Sometimes, camouflage (the use of cosmetics) is the best option to hide the scars.
