The barbed suture lift procedure provides moderate long-term and sustained improvement for facial laxity, with most improvement seen in the tear trough/malar fat pads and nasolabial folds. In this study, clinical efficacy was seen up to 16 months postprocedure.

Background: Botulinum toxin type A (BTX) is used prophylactically to reduce the frequency of migraine headaches, with inconsistent responses reported in the literature. The purpose of our study was to determine whether BTX injections at doses used for upper-face cosmetic purposes, which differ from doses typically used by headache specialists, could prevent imploding and ocular but not exploding migraines. Observations: Study participants were recruited among patients who had received or were planning to receive BTX injections for upper-face cosmetic purposes but also reported having migraines. Among the 18 patients who completed the study, most with imploding and ocular migraines experienced a significant reduction in their headache frequency, whereas those with exploding migraines generally did not. Conclusions: Our study supports the hypothesis that patients with imploding and ocular migraines are more responsive to BTX than those with exploding migraines. Injections of BTX at doses appropriate for cosmetic purposes may be sufficient to prevent migraine attacks.

Hyperproliferative epidermal disorders range from benign hyperplasias such as psoriasis to basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), the two most common cancers in the US. While they all arise from the epidermis, these diseases differ dramatically in biological behavior and their underlying gene expression patterns have not been compared. We thus examined mRNA transcript levels in these disorders to identify and further characterize differentially expressed genes. Transcript expression patterns distinguish these disorders and identify EGR1, among other genes, whose epidermal expression is decreased in BCC and SCC but is elevated in psoriasis. Egr-1 inhibits growth of benign and malignant epidermal cells in vitro and appears to suppress both Cdc25A expression and Cdk2 dephosphorylation. These data indicate that gene expression profiling can differentiate epidermal hyperproliferative diseases and suggest that Egr-1 may play a role in preventing uncontrolled epidermal growth.
