ABSTRACT
BACKGROUND: External ultrasonic tumescent liposuction represents a new application of ultrasound energy to the standard tumescent liposuction procedure. Hoping to retain the in vivo properties of ultrasonic delivery while avoiding the growing number of invasive complications, external ultrasonic tumescent liposuction is a new technique with the potential of improving traditional tumescent liposuction therapy. OBJECTIVE: The purpose of this preliminary study was to evaluate the role of external ultrasonic tumescent liposuction as an adjunct to traditional tumescent liposuction. METHODS: Ten patients underwent standard tumescent liposuction with the addition of 10 minutes of preoperative ultrasound therapy applied to one-half of their targeted treatment regions. Both objective and subjective parameters were assessed during the subsequent side-by-side evaluations. RESULTS: Six of the 10 cases had a measurable increase in the amount of supernatant fat extracted per unit of aspirate volume from those regions pretreated with ultrasound energy. In five of the 10 cases, the operating physician noted slightly easier cannula maneuverability through adipose tissue on the ultrasound side. Roughly half of the patients had an improved postoperative course, with less swelling/edema, less bruising or ecchymoses, more skin retraction, and less postoperative pain/discomfort. CONCLUSION: The favorable results of this preliminary study warrant further investigation and research into external ultrasonic tumescent liposuction as an adjunct to the traditional tumescent liposuction procedure.

BACKGROUND: Angiolymphoid hyperplasia (ALH) with eosinophilia is a benign rare tumor, characterized by marked proliferation of endothelial cells. The tumors are associated with extensive infiltrate of lymphocytes, histiocytes, and eosinophils, and occur on the head and neck of young adults. A variety of treatments have been attempted with frequent recurrences. We report two cases of ALH with eosinophilia that seemed to be dependent on sex hormones. OBSERVATION: The first case is a patient with ALH that resolved after stopping treatment with birth control pills. Biopsy specimens of the tumor demonstrated increased level of estrogen and progesterone receptors compared with her normal skin. The second case is a patient with a previous lesion of ALH with eosinophilia, who during pregnancy had new lesions develop and whose primary lesion increased in size. All lesions decreased to half their original sizes after pregnancy. CONCLUSION: Both of these cases suggest a role for hyperestrogen states with the presence of hormonal receptors. The response to sex hormones could contribute to the pathogenesis of the disease and may offer future alternative treatment modalities.

The awareness of sun-induced skin damage has increased in both the lay public and physician. Coincidentally, there has been progress in the development of new ultraviolet-(UV) radiation protecting sunscreens. In this review and update on sunscreens, sunscreen classification, UVB and UVA protection, sunscreen vehicle, and substantivity will be addressed.
