Onychomycoses represent a group of nail affections caused by one or more fungi. Whether aging represents a risk factor for developing onychomycosis, remains a question. In the present work, we studied the variations in frequency and prevalence of onychomycoses and non-mycotic onychodystrophies according to age. Our results show that there is an increase in the frequency and prevalence of onychomycoses and non-mycotic onychodystrophies predominantly in patients over forty years of age. [less ▲]

Chemical peels induce the destruction and exfoliation of the epidermis using selected caustic substances. The specific properties of these agents result in a limited and controlled destruction of epidermal layers and of the superficial dermis. The choice of the appropriate method, the preparatory phase and the post-peeling care are very important to reach optimal results. Some types of peeling are routinely used. We briefly report those designed for the superficial and medium depth peelings. The topical application of glycolic acid at high concentration induces a superficial peel resulting in shading of small wrinkles. Trichloracetic acid used at an appropriate concentration acts more deeply and thus represents a good indication for more severe signs of ageing. These peels have been used for decades by dermatologists to improve the visible signs of skin ageing and to treat some alterations of the cutaneous relief. [less ▲]

Sensory irritation is directly bound to the concept of sensitive skin. A large proportion of the population, in particular young women, is affected. The reported symptoms are those of skin discomfort without any visible alteration of the skin. According to the subjects, the timing and the cutaneous sites, various perceptions occur, including pruritus, burning and stinging sensations. Sensory irritation is difficult to quantify because it remains subjective by essence. The condition is sometimes aggravated by some cosmetics, cleaning and cleansing products, wool contact and exposure to cold and dry climate. The responsible ingredients are often agents affecting functions of stratum corneum without being obvious chemical irritants. [less ▲]

The topical treatment of psoriasis benefits from the alternate use of dermocorticosteroids and vitamin D3 analogues. A new galenic formulation allows to combine them in a single application. Dovobet (LEO Pharma) ointment is the association of calcipotriol 50 microg/g with betamethasone dipoprionate 0.5 mg/g. This formulation boosts the therapeutic activity of calcipotriol. It also decreases the irritative inflammatory reaction due to calcipotriol without increasing the atrophogenic risk of the dermocorticoid. [less ▲]

Oral administration of lithium is used as treatment in psychiatry. The drug frequently induces cutaneous side effects corresponding to acneiform or maculo-papular eruptions, psoriasis and folliculitis. Men are more frequently affected than women. These manifestations are characterized by the accumulation of neutrophils in the skin. Alopecia and classical drug reactions are also possible. Topical applications of lithium used to treat some dermatoses do not induce similar side effects, probably because dosages are much lower. [less ▲]

The treatment of drug-induced toxic epidermal necrolysis (TEN) remains unsatisfactory. Intravenous immunoglobulins (IVIg) and intravenous cyclosporin A (CsA) have shown some efficacy in short series of patients. We assessed the effects of IVIg and CsA on TEN lesional and apparently uninvolved skin using standard histology and immunohistochemistry. Cutaneous biopsies were taken from necrotic and clinically uninvolved TEN skin at admission (D1) before any treatment, and after a 5-day treatment (D5). Two IVIg-treated patients (0.75 g/kg/day), two CsA-treated patients (5 mg/kg/day) and two control patients only receiving supportive care were compared. Biopsies were examined by standard histology and immunohistochemistry using antibodies directed to CD68 antigen (macrophages), CD45R0 antigen (activated T lymphocytes), Factor XIIIa (dermal dendrocytes) and the CD95 receptor (apoptosis marker). The different cell densities were evaluated by computerized image analysis. The clinical outcomes with the different treatments were also recorded. There was no obvious difference in the duration of hospitalization in intensive care unit between the three groups but one patient passed away in each of the IVIg- and CsA-groups. At D5, no differences were found between the three groups in the histological and clinical rate of re-epithelialization, and in the evolution of T lymphocyte, macrophage and dendrocyte densities in the epidermis and dermis. However, the expression of the CD95 receptor was similarly and strongly abated at D5 in the epidermis of IVIg- and CsA-treated patients, while it was conversely increased in the two patients under supportive care only. Such a difference was found both in necrotic and uninvolved sites. IVIg and CsA treatments thus appeared to exert no obvious effect on the inflammatory infiltrate, but both abated the expression of the CD95 receptor in the skin of TEN patients. This effect did not seem sufficient to fully reverse the clinical evolution of the disease. It is inferred that IVIg and CsA do not completely abate the TEN process. [less ▲]

Among acute phase proteins, haptoglobin is considered as the most interesting in cattle. Due to its early and marked increase in acute inflammation, it is useful for the diagnosis and prognosis of acute inflammation and for the evaluation of treatment. Physiological variations of its serum concentrations can be observed in the days following parturition. From very low or even undetectable concentrations, its serum levels can rise significantly during acute inflammation. Haptoglobin could improve the sanitary control of animals and the identification of pathologies even before clinical signs become apparent. It could also detect subclinical diseases and improve the sanitary control at the slaughterhouse, because haptoglobin has a good combination of specificity and sensitivity in such a context. At the herd scale, it could be used to evaluate the sanitary status in order to allocate it a quality label. [less ▲]

Le développement durable est souvent présenté comme l'aboutissement naturel de la montée des préoccupations environnementales. Il a pourtant constitué un tournant dans l'appréhension des problèmes environnementaux car il a modifié le débat public autour de cette problématique et a ouvert un espace d'action pour de nouveaux acteurs. Porteur d'une vision conciliatrice entre objectifs économiques et environnementaux, le développement durable s'inscrit dans une approche de l'écologisation comme "modernisation" de la techno-sphère qui se démarque de la pensée écologiste.

The small GTPases of the Rho family are key intermediates in cellular signalling triggered by activated cell-adhesion receptors. In this study, we took advantage of RNA interference (RNAi) using small interfering RNAs (siRNAs) to define the roles of the best-characterized members of the RhoGTPase family, RhoA, Rac1 and Cdc42, in the control of MMP-1, MMP-2 and type-I-collagen expression in normal human skin fibroblasts (HSFs). A specific and long-lasting repression, up to 7 days after transfection, of the three GTPases was achieved by transient transfection of specific siRNA. The silencing of Cdc42, but not that of RhoA or Rac1, induced a 15-fold increase in MMP-1 secretion. This upregulation was confirmed at the mRNA level and observed with two different siRNAs targeting Cdc42. Such a regulation was also observed in various human cell lines and was rescued by re-expressing wild-type Cdc42 encoded by a construct bearing silent mutations impeding its recognition by the siRNA. By contrast, MMP-2 and type-I-collagen expression was not affected by the individual silencing of each Rho GTPase. Cytokine protein array, enzyme-linked immunosorbent assays and reverse-transcription PCR measurements revealed that ablation of Cdc42 induced an overexpression of interleukin 8 and MCP-1. Although these cytokines are known to induce the expression of MMP-1, we showed that they were not involved in the Cdc42-mediated upregulation of MMP-1. Silencing of Cdc42 also induced an increased phosphorylation of ERK1/2 and p38 MAP kinase. The use of chemical inhibitors on Cdc42-ablated cells revealed that the upregulation of MMP-1 is dependent on the ERK1/2 pathways, whereas the p38 MAP kinase pathway displayed an inhibitory role. Simultaneous knock-down of two or three Rho GTPases allowed us to demonstrate that the RhoA-ROCK pathway was not involved in this regulation but that the silencing of Rac1 reduced the effect of Cdc42 suppression. These data suggest that, in vivo, when cell/extracellular-matrix interactions via integrins induce cytoskeleton organization, MMP-1 expression is maintained at a low level by Cdc42 via a repression of the Rac1 and ERK1/2 pathways. Therefore, Cdc42 contributes to ECM homeostasis and connective tissue integrity. [less ▲]
