Ehlers-Danlos syndrome (EDS) is heterogenous with regard to genetic traits, clinical manifestation, the biomechanical and microscopic properties of connective tissues, and basic molecular defects. We report on nine relatives of four generations who suffered from large vessel dissections and cutaneous microscopic changes consistent with EDS. Measurements of the mechanical properties of skin were performed using a computerized suction device (Cutometer). Morphological and biomechanical alterations suggestive of EDS were present in all examined subjects. A loose network of collagen bundles was admixed with clumsy elastic fibres. Factor XIIIa-positive dermal dendrocytes looked almost normal but were slim and rarefied in four subjects. The severity in ultrastructural alterations of the collagen network differed among the subjects. The group with the most prominent changes showed the most striking biomechanical alterations characterized by increased biologic elasticity without any excess in skin extensibility. A positive correlation was found between skin extensibility and elasticity. In conclusion, distinct alterations in the collagen scaffolding were found to be correlated to variable severity in biomechanical alterations of the skin. The predictive value of these changes for large vessel dissections in some families at risk remains to be settled. [less ▲]

Acne is a multifaceted disorder. Its clinical presentation differs according to the age and gender of the subjects. Acne of the adolescent is a frequent disorder. Some topical and oral antibiotics have proven their efficacy. However, the risk of bacterial resistance may be a concern for the clinicians and their patients. Hence, a therapeutic strategy without antibiotics merits to be considered. Retinoids have a place of choice in this therapeutic strategy. Benzoyl peroxide and miconazole are also active and valuable agents in this therapeutic algorithm. [less ▲]

A critical step in establishment of human pregnancy is the invasion of the uterus wall by the extravillous cytotrophoblast (EVCT), a process regulated by multiple autocrine and paracrine factors. Hormones belonging to the GH/prolactin family are expressed at the maternofetal interface. Because they are involved in cell motility in various models, we examined the possible regulatory role of human placental GH (hPGH) in EVCT invasiveness. By using an in vitro invasion model, we found that EVCT isolated from first-trimester chorionic villi and cultured on Matrigel secreted hPGH and expressed human GH receptor ( hGHR). These data were confirmed by in situ immunohistochemistry. EVCT expressed the full-length and truncated forms of hGHR, and the Janus kinase-2/signal transducer and activator of transcription factor-5 signaling pathway was activated in EVCT by hPGH treatment. Strong hPGH and hGHR expression was observed when EVCT invaded Matrigel and moved through the pores of the filter on which they were cultured. hPGH stimulated EVCT invasiveness, and this effect was inhibited by a Janus kinase-2 inhibitor. Interestingly, hPGH was more efficient than pituitary GH in stimulating EVCT invasiveness. These results offer the first evidence for a placental role of hPGH and suggest an autocrine/ paracrine role of hPGH in the regulation of trophoblast invasion. [less ▲]

BACKGROUND: Histological structures of the skin are often irregular in size and shape. Euclidean geometry and fractal analysis are complementary for assessing distinct aspects of their dimensions. OBJECTIVE: To determine and compare the variations in shape of the dermo-epidermal junction and the size of the superficial vessels in psoriatic lesions. METHOD: The relative microvasculature area and the fractal dimension D of the dermo-epidermal interface were measured inside and outside growth-stunted guttate lesions (n = 22) and expanding plaques (n = 37) in psoriasis of the trunk. RESULTS: The median D values of the dermo-epidermal interface were significantly larger (p < 0.01) in psoriatic plaques (D = 1.15) than in guttate lesions (D = 1.08), and these D values on lesional skin were significantly larger (p < 0.01) than in the uninvolved skin (D = 1.03). The microvasculature was significantly (p < 0.01) more developed in lesional (plaque: 13%, guttate: 8.20%) than in uninvolved skin (3.60 and 3.85%). No correlations were found between the relative microvasculature areas and the D values of the dermo-epidermal interface, both in the uninvolved and lesional skins of each psoriatic type. CONCLUSION: The absence of a relationship between modulations of the dermo-epidermal junction and vascular hyperplasia, both in expanding and stable psoriasis lesions, suggests that these events are regulated by different mechanisms and do not depend on each other.

A consultation motivated by an enlarged red leg is a common situation. The causes are multiple and the diagnosis primarily relies on case history and physical examination distinguishing inflammatory red legs from erythemato-violaceous presentations. Additional diagnostic search cannot be described as a single standardized procedure. Each disease calls for specific and different paraclinical investigations. The most frequent cause is erysipelas or a thrombophlebitis. Some vascular malformations and some functional circulatory disturbances are also possible, as well as sequelae of panniculitis or borreliosis. [less ▲]

Previous studies have implicated acetylases and deacetylases in regulating the transcriptional activity of NF-kappaB. Here, we show that inhibitors of deacetylases such as trichostatin A (TSA) and sodium butyrate (NaBut) potentiated TNF-induced expression of several natural NF-kappaB-driven promoters. This transcriptional synergism observed between TNF and TSA (or NaBut) required intact kappaB sites in all promoters tested and was biologically relevant as demonstrated by RNase protection on two instances of endogenous NF-kappaB-regulated gene transcription. Importantly, TSA prolonged both TNF-induced DNA-binding activity and the presence of NF-kappaKB in the nucleus. We showed that the p65 subunit of NF-kappaB was acetylated in vivo. However, this acetylation was weak, suggesting that other mechanisms could be implicated in the potentiated binding and transactivation activities of NF-kappaB after TNF plus TSA versus TNF treatment. Western blot and immunofluorescence confocal microscopy experiments revealed a delay in the cytoplasmic reappearance of the IkappaBalpha inhibitor that correlated temporally with the prolonged intranuclear binding and presence of NF-kappaB. This delay was due neither to a defect in IkappaBalpha mRNA production nor to a nuclear retention of IkappaBalpha but was rather due to a persistent proteasome-mediated degradation of IkappaBalpha. A prolongation of IkappaB kinase activity could explain, at least partially, the delayed IkappaBalpha cytoplasmic reappearance observed in presence of TNF plus TSA. [less ▲]

Skin is subjected to many environmental threats, some of which altering the structure and function of the stratum corneum. Among them, surfactants are recognized factors that may influence irritant contact dermatitis. The present study was conducted to compare the variations in skin capacitance and corneosurfametry (CSM) reactivity before and after skin exposure to repeated subclinical injuries by 2 hand dishwashing liquids. A forearm immersion test was performed on 30 healthy volunteers. 2 daily soak sessions were performed for 5 days. At inclusion and the day following the last soak session, skin capacitance was measured and cyanoacrylate skin-surface strippings were harvested. The latter specimens were used for the ex vivo microwave CSM. Both types of assessments clearly differentiated the 2 hand dishwashing liquids. The forearm immersion test allowed the discriminant sensitivity of CSM to increase. Intact skin capacitance did not predict CSM data. By contrast, a significant correlation was found between the post-test conductance and the corresponding CSM data. In conclusion, a forearm immersion test under realistic conditions can discriminate the irritation potential between surfactant-based products by measuring skin conductance and performing CSM. In vivo skin preconditioning by surfactants increases CSM sensitivity to the same surfactants. [less ▲]

Acne is a multifactorial disorder affecting the vast majority of adolescents and young adults. Among the therapeutic armamentum, estroprogestative contraception can be offered to young women. The choice must, however, be carefully targeted because the estroprogestative associations do not show similar anti-acne efficacy. A new contraceptive associating 20 micrograms of ethinyl estradiol and 100 micrograms of levonorgestrel (Lowette) has proven its clinical efficacy in this indication. [less ▲]

Background : The aspect of hair depends on the spatial organization of the hair shafts and on their chemical, physical and structural integrity. Some genetic disorders and exogenous influences may affect it. Aims : In vivo objective assessments are welcome in order to compare the consequences of hair damages and to assess the kinetics of the changes occurring in time after damaging or attempting to repair the hair structure. Method : Ultrasound shear wave propagation measured on hair is introduced as an objective non-invasive method with in vitro and in vivo applications. Results : With multiple measurements made on the scalp of 72 Caucasians, hair felting following damage appeared to be associated with an increase in the coefficient of variation of the shear wave velocity measurements. Maximum hydration of hair locks increased the shear wave velocity in vitro and decreased the intraindividual range of data. The relevance of the method and reproducibility of data was influenced by the experimentalist skill. Conclusion : Ultrasound shear wave propagation on hair is influenced by the physical integrity of the hair shafts and on their three-dimensional arrangement. [less ▲]

Ketoconazole (KET) and zinc pyrithione (ZPT) are compounds active against the Malassezia spp. yeasts, which are believed to play a major role in dandruff and seborrheic dermatitis. We compared the efficacy and safety of KET 2% and ZPT 1% in shampoo formulations for the alleviation of severe dandruff and seborrheic dermatitis. This open randomized, parallel-group trial began with a 2-week run-in phase during which subjects applied a neutral non-antidandruff shampoo. It was followed by a 4-week randomized treatment phase and a subsequent 4-week follow-up phase without treatment. Shampooing during the treatment period was carried out twice weekly for the KET group and at least twice weekly for the ZPT group in accordance with the label instructions. A total of 343 subjects were recruited to enter the trial. Of the 331 eligible volunteers, 171 were randomized to KET 2% and 160 to ZPT 1%. Clinical assessments were performed. Beneficial effects were evidenced for both medicated shampoos, but the effect was significantly better for KET 2%, which achieved a 73% improvement in the total dandruff severity score compared with 67% for ZPT 1% at week 4 (p < 0.02). The recurrence rate of the disease was also significantly lower following KET 2% treatment than following ZPT 1% treatment. As a consequence, the overall clearing of the skin condition at the end of treatment and follow-up phase was in favor of the KET 2% formulation (p = 0.004). Side effects were minimal. It is concluded that after a 4-week treatment, KET 2% shampoo was significantly superior to ZPT 1% shampoo in the treatment of subjects with severe dandruff or seborrheic dermatitis of the scalp. It is our assumption that this difference is noticeable for the patient and as a consequence relevant. Both formulations were well tolerated. [less ▲]

Hair shedding and hair thinning have been reported to be affected by dandruff and seborrhoeic dermatitis. The present study was conducted in 150 men presenting with telogen effluvium related to androgenic alopecia associated with dandruff. They were randomly allocated to three groups receiving each one of the three shampoos in the market containing either 1% ketoconazole (KTZ), 1% piroctone olamine (PTO) or 1% zinc pyrithione (ZPT). Shampoos had to be used 2-3 times a week for 6 months. Hair shedding during shampoo was evaluated semiquantitatively. Hair density on the vertex was evaluated on photographs using a Dermaphot. Trichograms were used for determining the anagen hair percentage and the mean proximal hair shaft diameter using computerized image analysis. The sebum excretion rate (SER, mug cm(-2) h(-1)) was also measured using a Sebumeter((R)). The three treatments cleared pruritus and dandruff rapidly. At end point, hair density was unchanged, although hair shedding was decreased (KTZ: -17.3%, PTO: -16.5%, ZPT: -10.1%) and the anagen hair percentage was increased (KTZ: 4.9%, PTO: 7.9%, ZPT: 6.8%). The effect on the mean hair shaft diameter was contrasted between the three groups of volunteers (KTZ: 5.4%, PTO: 7.7%, ZPT: -2.2%). In conclusion, telogen effluvium was controlled by KTZ, PTO and ZPT shampoos at 1% concentration. In addition, KTZ and PTO increased the mean hair shaft thickness while discretely decreasing the sebum output at the skin surface. [less ▲]
