Eighty-five people aged 2-76 years with 250 common and plantar warts were followed prospectively for 9 months. The majority (57; 67%) had one to two warts. Of the 54 subjects who had a past history of warts, 41 (75.9%) had sought treatment for them. Twenty-four (58.5%) said that treatment had been unsuccessful; 22 (53.7%) experienced pain during their treatment; 14 (34.1%) said that treatment had been inconvenient; nine (22%) required multiple treatments; and eight (19.5%) said the treatment resulted in the development of scars. The quality-of-life assessment related to their current warts revealed that 81.2% were moderately to extremely embarrassed by them; 70.5% were moderately to extremely concerned about negative appraisal by others for having them; 24.7% said that it was moderately to extremely difficult to play sport because of their warts. Moderate to severe discomfort from their warts occurred in 51.7% of people and 35.4% said they had moderate to severe pain. During the 9-month study period, 27 (31.8%) of the participants had at least one wart regress spontaneously with 49 (19.6%) of the 254 warts regressing during that time. These data confirm the impression that a wart is not merely a blemish on the skin. Warts have the potential to cause considerable morbidity at times; this should be taken into account when a patient asks for treatment.
Background Tissue fillers are generally safe and well tolerated by patients. However, complications do occur and may be very severe, such as intravascular injection (with occasional residual tissue loss, visual and neurological sequelae) and late nodularity and swelling. Methods to lessen the likelihood of complications have been the subject of much recent literature. Depth of injection has been identified as a key safety consideration. Patients/Methods The role of injection of facial filler into the muscular layer of the face is explored in this article. Literature was explored using available search facilities to study the role of injections in or around this layer in the production of significant adverse reactions. Results A body of literature seems to suggest that injection into mimetic musculature of the face especially the musculature in the periorbital and perioral regions is prone to adverse reactions. Conclusions Injection of agents into the perioral and periorbital mimetic muscular layer may produce, product clumping, displacement, and tendency to late nodularity and swelling. It also risks intravascular injection as compared to injection of other layers of the face. Injection into the mimetic muscles especially the sphincteric muscles should be avoided to minimize the risk of complications.
Background The pathogenesis of delayed onset tissue nodules (DTNs) due to hyaluronic acid (HA) injections is uncertain. Objectives To formulate a rational theory for DTN development and their avoidance and treatment. Methods A multi-disciplinary and multi country DTN consensus panel was established with 20 questions posed and consensus sought. Consensus was set at 75% agreement. Results Consensus was reached in 16/20 questions regarding the pathogenesis of DTNs forming the basis of a classification and treatment guide. Conclusions The group believe that filler, pathogens and inflammation are all involved in DTNs and that DTNs most likely are infection initiated with a variable immune response. Injected filler may incorporate surface bacteria, either a commensal or a true pathogen if the skin barrier is altered. The initially High molecular weight HA (HMWHA) filler is degraded to Low molecular weight HA (LMWHA) at the edge of the filler. Commensals positioned within the filler bolus may be well tolerated until the filler is degraded and the commensal becomes visible to the immune system. LMWHA is particularly inflammatory in the presence of any local bacteria. Commensals may still be tolerated unless the immune system is generally heightened by viraemia, or vaccination. Systemic pathogenic bacteraemia may also interact with the filler peripheral LMWHA, activating Toll Like receptors inducing DTN formation. Given this scenario, attention to practitioner and patient hygiene and early systemic infection treatment deserve attention. Classification and treatment systems were devised by considering each of the 3 factors of filler, inflammation, and infection separately.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
