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.
A total of 685 clinical isolates from patients with pneumococcal diseases were collected from 14 centers in 11 Asian countries from January 2000 to June 2001. The in vitro susceptibilities of the isolates to 14 antimicrobial agents were determined by the broth micro dilution test. Among the isolates tested, 483 (52.4%) were not susceptible to penicillin, 23% were intermediate, and 29.4% were penicillin resistant (MICs ≥ 2 mg/liter). Isolates from Vietnam showed the highest prevalence of penicillin resistance (71.4%), followed by those from Korea (54.8%), Hong Kong (43.2%), and Taiwan (38.6%).
The treatment for stretch marks is limited, and there is no curative treatment. The most invasive therapies for stretch marks involve physician-administered laser surgery. 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.
