Meshkinpour et al (2005) examined the safety and effectiveness of the ThermaCool TC radiofrequency system for treatment of hypertrophic and keloid scars and assessed treatment associated collagen changes. Six subjects with hypertrophic and 4 with keloid scars were treated with the ThermaCool device: 1/3 of the scar received no treatment (control), 1/3 received one treatment and 1/3 received 2 treatments (4-week interval). Scars were graded before and then 12 and 24 weeks after treatment on symptoms, pigmentation, vascularity, pliability, and height. Biopsies were taken from 4 subjects with hypertrophic scars and evaluated with hematoxylin and eosin (H & E) staining, multi-photon microscopy, and pro-collagen I and III immunohistochemistry. No adverse treatment effects occurred. Clinical and H & E evaluation revealed no significant differences between control and treatment sites. Differences in collagen morphology were detected in some subjects. Increased collagen production (type III > type I) was observed, appeared to peak between 6 and 10 weeks post-treatment and had not returned to baseline even after 12 weeks. The authors concluded that use of the thermage radiofrequency device on hypertrophic scars resulted in collagen fibril morphology and production changes. ThermaCool alone did not achieve clinical hypertrophic scar or keloid improvement. They noted that the collagen effects of this device should be studied further to optimize its therapeutic potential for all indications.
Oral preparations combining ergotamine and caffeine (Cafergot) are available, as are rectal suppositories. Dihydroergotamine (DHE), a semisynthetic ergot alkaloid and nonselective 5-HT 1 receptor agonist, is considered to be more appropriate for the treatment of severe migraines. It is available in parenteral preparations and as a nasal spray. Like ergotamine, DHE has oxytocic properties, precluding its use in pregnancy. Because of their ability to cause peripheral vasoconstriction, ergot alkaloids should not be used chronically. The ergotamine derivatives used to treat migraines are described in Table 7 . 4 , 16 - 18 , 22
As a flat chested WOMAN (not girl), I would rather keep my small boobs thank you. I've seen and heard too many horror stories regarding having large breasts that I stay clear away from surgery or anything else trying to convince me my breasts aren't good enough, especially shallow men. Besides my tiny boobies have attracted real intelligent gentlemen, and very few jerks. I truly believe that if I had a breast enlargement, I would properly only attract retarded, shallow, ugly on the inside types...so I'm very happy with my small breasts.
