These experiments offer further insight into the use of dialysis as an experimental technique in the skin. They provide direct evidence that the skin microvascular response to ACh is only partially mediated by NO. Further they suggest that ACh at higher concentrations can induce an axon-reflex-mediated response that is independent of NO release at the site of dermal provocation or of local histamine release.

Pyogenic granuloma is a benign vascular proliferation of the skin and mucous membranes, whose pathogenesis is not fully understood. Despite its benign nature, it can have a significant negative impact on patients’ quality of life, and therefore appropriate therapy is needed. Over the years, a lot of therapeutic modalities have been used in order to successfully treat this condition. This paper is an updated systematic overview of all the reported successful treatments described in the literature and was conducted according to the PRISMA guidelines for systematic reviews. Articles derived from the databases PubMed, EMBASE, and SCOPUS, published between 1981 and 2018, were analyzed for this study. In the literature, there are several studies, case series, and case reports that demonstrate encouraging results with the use of various methods, such as surgical intervention or laser treatment, but also with more conservative approaches, including the application of topical and systemic agents. The selection of the appropriate treatment should be made individually, depending on severity of the disease and patient characteristics. Both research efforts as well as clinical reporting are necessary in order to provide more insight on the management of these vascular tumors. This paper aims to provide a summarized update on the reported therapies and to raise awareness for the need to conduct larger systematic studies in order to adequately evaluate and compare the effectiveness of the presented therapeutic strategies.

Background: Accumulating evidence suggests that synthetic retinoids may be capable of affecting the differentiation and growth of nervous tissue in vivo and in vitro. On the other hand, adverse reactions concomitant with brainstem involvement definitely or probably related to oral retinoid therapy have been reported in a small number of patients. Objective: The purpose of the present study was to substantiate the possible effects of oral isotretinoin on the synaptic activity and propagation of action potentials along the nerve fibers. Methods: The auditory brainstem response of 33 patients with severe nodulocystic acne before and 3 weeks after the onset of oral isotretinoin administration was investigated using auditory evoked potentials. Results: The paired analysis of the response variables before and after treatment failed to reveal any statistically significant differences. However, a marked increase in latencies and interpeak latencies and a decrease in amplitudes for both ears were found in 3 patients after therapy. Conclusions: It seems reasonable to suggest that these subclinical changes may be due to an isotretinoin-induced synaptic malfunction or to a conduction defect in the auditory nerve fibers.

Background: The introduction of Immune Checkpoint Inhibitors in the recent years has resulted in high response rates and extended survival in patients with metastatic/advanced malignancies. Their mechanism of action is the indirect activation of cytotoxic T-cells through the blockade of inhibitory receptors of immunomodulatory pathways, such as cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4), programmed cell death protein-1 (PD-1) and its ligand (PD-L1). Despite their impressive therapeutic results, they can also induce immune-related toxicity, affecting various organs, including the skin. Objective: To provide an updated summarized overview of the most common immune-mediated cutaneous side effects and their management. Method: English articles derived from the databases PubMed and SCOPUS and published between 2009 and 2018, were analyzed for this narrative review. Results: The most common adverse cutaneous reactions include maculopapular rash, lichenoid reactions, vitiligo and pruritus, with severity Grade 1 or 2. Less frequent but eventually life-threatening skin side effects, including Stevens-Johnson syndrome, Drug Reaction with Eosinophilia and Systemic Symptoms and Toxic Epidermal necrolysis, have also been reported. Conclusion: Basic knowledge of the Immune-Checkpoint-Inhibitors-induced skin toxicity is necessary in order to recognize these treatment-related complications. The most frequent skin side effects, such as maculopapular rash, vitiligo and pruritus, tend to subside under symptomatic treatment so that permanent discontinuation of therapy is not commonly necessary. In the case of life-threatening side effects, apart from the necessary symptomatic treatment, the immunotherapy should be permanently stopped. Information concerning the management of ICIs-mediated skin toxicity can be obtained from the literature as well as from the Summary of Product Characteristics of each agent.

Background Mesotherapy is a procedure that involves the injection of active substances into the dermis and subcutaneous tissue in order to treat several local medical and cosmetic conditions. Despite being considered as a relatively safe method, a series of adverse reactions can occur due to its wide application and lack of standardization processes. Objectives The aim of this paper is to summarize all the mesotherapy‐related complications published so far, and to provide an insight into their management. Patient/Methods Articles derived from the databases, PubMed, EMBASE, and SCOPUS, and published between 1992 and 2018, were analyzed for this review. The study was conducted according to the PRISMA guidelines. Results In this literature, there is a number of case series and isolated case reports describing various side effects of different severities. The therapeutic management of these complications is—in most cases—individualized. Conclusions Larger systematic studies are needed in order to adequately evaluate the safety profile of mesotherapy, and in order to determine standardized therapy parameters, so as to minimize the risk of potential adverse reactions.

The effect of two naturally occurring (retinol and alltrans retinoic acid) and two synthetic (isotretinoin and acitretin) analogs of vitamin A (retinoids) on tRNA biogenesis was investigated employing the RNase P of Dictyostelium discoideum as an in vitro experimental system. RNase P is an ubiquitous and essential enzyme that endonucleolytically cleaves all tRNA precursors to produce the mature 5 end. All retinoids tested revealed a dose-dependent inhibition of RNase P activity, indicating that these compounds may have a direct effect on tRNA biogenesis. Detailed kinetic analysis showed that all retinoids behave as classical competitive inhibitors. The K i values determined were 1475 M for retinol, 15 M for all-trans retinoic acid, 20 M for isotretinoin, and 8.0 M for acitretin. On the basis of these values acitretin is a 184, 2.5, and 1.9 times more potent inhibitor, as compared with retinol, isotretinoin, and all-trans retinoic acid, respectively. Taking into account that retinoids share no structural similarities to precursor tRNA, it is suggested that their kinetic behavior reflects allosteric interactions of these compounds with hydrophobic site(s) of D. discoideum RNase P.Retinoids, a group of natural and synthetic analogs of vitamin A, play an essential role in vision, growth, and reproduction as well as exhibiting striking effects on cell proliferation, differentiation, and pattern formation during development (1, 2). The discovery that members of the steroid/thyroid hormone receptor superfamily are nuclear retinoic acid-binding proteins tremendously improves our understanding of the mechanisms that mediate the regulatory action of retinoids on gene expression (3-6). The retinoid receptors are ligand-activated, DNAbinding, transcription factors (7,8).Due to their ability to regulate cell differentiation and suppress or reverse the malignant phenotype, retinoids have a potential use as chemopreventive and chemotherapeutic agents in cancers of skin and other organs (9 -11). Moreover, oral synthetic retinoids are presently successfully applied in the management of severe and recalcitrant dermatoses, which were previously regarded as frustrating therapeutic problems (12)(13)(14).RNase P is a key enzyme in tRNA biogenesis, which cleaves all tRNA precursors endonucleolytically to produce the mature 5Ј end. RNase P enzymes are composed of both RNA and protein (15). In vitro, RNA subunits of bacterial enzymes are catalytically active in the absence of protein (16) and are the only known RNA catalysts naturally devoted to act in trans (17). Catalytic activity of RNA subunits, in the absence of protein subunits, has not been demonstrated so far for archaea and eukaryotes RNase P. However, the catalytic center of these RNase P enzymes most likely is associated with the RNA subunits. Eukaryotic RNase P activity has been detected in nuclei, mitochondria, and chloroplasts (15,18). Recently, the partial purification and characterization of RNase P from the slime mold Dictyostelium discoideum has been reported (18,19)....
