RESUMO

Although molluscum contagiosum (MC) is a common infectious dermatosis that is self-resolving, treatment can diminish discomfort and decrease the risk of autoinoculation and infection to others, because it is transmitted through direct skin contact. This systematic review evaluates the efficacy of topical treatments for MC. A PubMed search following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed to find randomized, controlled trials of MC treatment. The search yielded 129 publications, but only 15 studies published between 1994 and 2020 were found to fit the inclusion criteria. Treatment modalities included podophyllotoxin, imiquimod, sodium nitrite, myrtle leaf extract, phenol, Salatac Gel (salicylic acid with lactic acid), potassium hydroxide, cantharidin, SB206, and VP-102. Outcomes were extracted from the literature, and subsequent quality and risk of bias assessments were performed. All treatments were more efficacious than the control except cantharidin, potassium hydroxide, and imiquimod, which had varying degrees of efficacy throughout studies. Overall, studies were of sufficient quality and had low risk of bias, but they had small sample sizes and lacked adequate explanation of statistical analysis. Current first-line treatment entails mechanical methods such as cryotherapy and curettage, which may be frightening to children with MC, so the development and assessment of topical treatments allows for alternative efficacious techniques.

RESUMO

BACKGROUND: Many traumatic brain injury (TBI) survivors live with persistent disability from chronic motor deficits despite contemporary rehabilitation services, underscoring the need for novel treatment. OBJECTIVE/HYPOTHESIS: We have previously shown that deep brain stimulation (DBS) of the lateral cerebellar nucleus (LCN) can enhance post-stroke motor recovery and increase the expression of markers of long-term potentiation in perilesional cerebral cortex. We hypothesize that a similar beneficial effect will be for motor deficits induced by unilateral fluid percussion injury (FPI) in rodents through long-term potentiation- and anti-inflammatory based mechanisms. METHODS: Male Long Evans rats with a DBS macroelectrode in the LCN underwent FPI over contralateral primary motor cortex. After 4 weeks of spontaneous recovery, DBS treatment was applied for 4 weeks, with the pasta matrix, cylinder, and horizontal ladder tests used to evaluate motor performance. All animals were euthanized and tissue harvested for further analysis by histology, immunohistochemistry, RNA microarray assay and Western Blot. RESULTS: LCN DBS-treated animals experienced a significantly greater rate of motor recovery than untreated surgical controls, with treated animals showing enhanced expression of RNA and protein for excitability related genes, suppressed expression of pro-inflammatory genes, suppressed microglial and astrocytic activation, but proliferation of c-fos positive cells. Finally, our data suggest a possible role for anti-apoptotic effects with LCN DBS. CONCLUSION: LCN DBS enhanced the motor recovery following TBI, possibly by elevating the neuronal excitability at the perilesional area and mediating anti-apoptotic and anti-inflammatory effects.
