ABSTRACT: Two new collagen-based lidocaine-containing dermal fillers, ArteSense™/ArteFill™ (Artes Medical, San Diego, CA) and Evolence® (Colbar LifeScience Ltd., Herzliya, Israel), have proved to be of particular interest to men, many of whom seek a long-lasting or permanent correction. ArteFill™ has been available in the United States since 2006, and it is expected that Evolence® will reach the American market in 2008. The properties of the two products will be described, and experience based on the administration of many hundreds of syringes of both products by a Canadian dermatologist will be detailed here, with tips and precautions to optimize patient outcomes. 相似文献

It is generally believed that ablative laser therapies result in prolonged healing and greater adverse events when compared with nonablative lasers for skin resurfacing. To evaluate the efficacy of ablative laser use for skin resurfacing and adverse events as a consequence of treatment in comparison to other modalities, a PRISMA‐compliant systematic review (Systematic Review Registration Number: 204016) of twelve electronic databases was conducted for the terms “ablative laser” and “skin resurfacing” from March 2002 until July 2020. Studies included meta‐analyses, randomized control trials, cohort studies, and case reports to facilitate evaluation of the data. All articles were evaluated for bias. The search strategy produced 34 studies. Of 1093 patients included in the studies of interest, adverse events were reported in a total of 106 patients (9.7%). Higher rates of adverse events were described in nonablative therapies (12.2% ± 2.19%, 31 events) when compared with ablative therapy (8.28% ± 2.46%, 81 events). 147 patients (13.4%) reported no side effects, 68 (6.22%) reported expected, transient self‐resolving events, and five (0.046%) presented with hypertrophic scarring. Excluding transient events, ablative lasers had fewer complications overall when compared with nonablative lasers (2.56% ± 2.19% vs 7.48% ± 3.29%). This systematic review suggests ablative laser use for skin resurfacing is a safe and effective modality to treat a range of pathologies from photodamage and acne scars to hidradenitis suppurativa and posttraumatic scarring from basal cell carcinoma excision. Further studies are needed, but these results suggest that ablative lasers are a superior, safe, and effective modality to treat damaged skin. 相似文献

Studies integrating clinicopathological and genetic features have revealed distinct patterns of genomic aberrations in Melanoma. Distributions of BRAF or NRAS mutations and gains of several oncogenes differ among melanoma subgroups, while 9p21 deletions are found in all melanoma subtypes. In the study, status of genes involved in cell cycle progression and apoptosis was evaluated in a panel of 17 frozen primary acral melanomas. NRAS mutations were found in 17% of the tumors. In contrast, BRAF mutations were not found. Gains of AURKA gene (20q13.3) were detected in 37.5% of samples, gains of CCND1 gene (11q13) or TERT gene (5p15.33) in 31.2% and gains of NRAS gene (1p13.2) in 25%. Alterations in 9p21 were identified in 69% of tumors. Gains of 11q13 and 20q13 were mutually exclusive, and 1p13.2 gain was associated with 5p15.33. Our findings showed that alterations in RAS‐related pathways are present in 87.5% of acral lentiginous melanomas. 相似文献

A 7‐week‐old girl, born at 30 weeks' gestational age, presented to clinic for evaluation of a crop of vesicular lesions that were noted after removal of a bandage that had been in place for 4 days. A punch biopsy of the lesion revealed fungal elements that were later identified as Rhizopus spp. The lesion began to self‐resolve, and no further treatment was needed, with full resolution of the lesion by 1 month after presentation. Clinicians should be aware of the variable presentations of mucormycosis and consider fungal infection in the differential diagnosis when evaluating vulnerable patients with skin eruptions. 相似文献

A black woman with the concurrent onset of two subcutaneous nodules located on the digits of her upper extremities is described. Initially, a single systemic disorder was considered; yet, the lesions differed in morphology and consistency. Microscopic examination of the nodules showed a giant cell tumor of tendon sheath and a lipoma. Although Occam's “razor” suggests that multiple lesions in the same person are more likely to represent variable manifestations of a single disorder than several different diseases in that individual, the simultaneously appearing lesions in this patient represented two different conditions. 相似文献

Psoriasis is a chronic inflammatory skin disorder resulting from a complex network of cytokines and chemokines produced by various immune cell types and tissue cells. Emerging evidence suggests a central role of IL-17 and IL-23/T17 axis in the pathogenesis of psoriasis, giving a rationale for using IL-17-blocking agents as therapeutics.Three agents targeting IL-17 signaling are being studied in Phase III clinical trials: secukinumab and ixekizumab (IL-17 neutralizing agents), and brodalumab (IL-17 receptor antagonist). Preliminary results are highly promising for all anti-IL17 agents, creating fair expectations on this class of agents as the new effective therapeutic approach for the treatment of psoriasis. 相似文献

Background and objectives
The negative impact of psoriasis on patient quality of life can be as important as the physical consequences of the disease. We could assume that clearance of the disease would also lead to an improvement in its psychosocial impact. The present study assesses the psychological state of patients with psoriasis receiving systemic treatment in a psoriasis unit, especially those with mild or no disease involvement.Methods
We performed a cross-sectional, observational, noninterventional epidemiological study of 2 cohorts (cases and controls). The patients self-completed demographic data and 4 questionnaires (Rosenberg Self-Esteem Scale, Skindex-29, HADS, and COPE-28 questionnaire) at a single visit.Results
We recruited 111 patients diagnosed with psoriasis and 109 control patients. In self-esteem, the mean and standard deviation (SD) score was 33.5 (4.8) for the psoriasis group and 33.3 (6.7) for the control group, with no significant differences. In the Skindex-29, the mean score for the psoriasis group was almost 3 times higher than that of the control group (30 vs. 11). Significant differences were found in the HADS scores of both groups (12.7 vs. 9.0, P < .001). The mean HADS-A scores were 8.0 (4.78) for the psoriasis group compared with 5.7 (3.8) for the control group (P < .001). In the case of HADS-D, the scores were 4.7 (3.9) compared with 3.2 (3.1) (P < .004), respectively.Conclusions
Our findings indicate that it is necessary to assess the psychological state of patients with psoriasis, because psychological effects persist even in cases where the disease is almost totally controlled. 相似文献15.
Combined effects of irritants and allergens. Synergistic effects of nickel and sodium lauryl sulfate in nickel- sensitized individuals 总被引:1,自引:0,他引:1
Knowledge of the combined effects of irritants and allergens is of interest with respect to accurate risk assessment. The threshold for elicitation of allergic contact dermatitis in previously sensitized individuals may theoretically be markedly influenced by the simultaneous presence of irritants and allergens. Combined exposures have, however, only been studied infrequently. In the present study, the combined effect of an irritant and an allergen was evaluated in a dose-response designed experimental study. 20 nickel-sensitized subjects were exposed to patch testing with varying concentrations of NiCl2 (nickel chloride) and sodium lauryl sulfate (SLS) alone and in combination. Evaluation of skin reactions was performed by colorimetry, measurement of transepidermal water loss and clinical evaluation, and the data were analyzed by logistic dose-response models. A synergistic effect was found of combined exposure to NiCl2 and SLS, as compared to each of the substances applied separately, as evaluated by colorimetry and clinical scoring. This means that the effect produced by the combined exposure was substantially greater than the effect produced by either of the substances alone. A synergistic effect of combined exposure on skin barrier impairment was not found, since the barrier function is significantly influenced by SLS-exposure only and not by NiCl2. Concentration limits are used by industry and government agencies to protect consumers. The present results clearly illustrate that elicitation thresholds and concentration limits may be influenced considerably by combined exposure to allergens and irritants. 相似文献

Desmoplakin mutations are associated with a wide variety of phenotypes affecting the skin, nails, hair, and heart. A 21‐month‐old boy was born with multiple erosions resembling epidermolysis bullosa, complete alopecia, nail dystrophy, palmoplantar keratoderma, and areas of follicular hyperkeratosis. He was found to have two heterozygous mutations in the desmoplakin gene: c.478 C>T in exon 4 (p.Arg160X) and c.3630T>A in exon 23 (Tyr1210X). This case expands the clinical spectrum associated with desmoplakin mutations and highlights a mutation in exon 23 that has not been previously reported in the literature. 相似文献

Most guidelines on neonatal skin care emphasize issues pertaining to healthy, term infants. Few address the complex task of skin barrier maintenance in preterm, very preterm, and extremely preterm infants. Here, we provide an evidence‐based review of the literature on skin care of preterm neonates. Interestingly, the stratum corneum does not fully develop until late in the third trimester, and as such, the barrier function of preterm skin is significantly compromised. Numerous interventions are available to augment the weak skin barrier of neonates. Plastic wraps reduce the incidence of hypothermia while semipermeable and transparent adhesive dressings improve skin quality and decrease the incidence of electrolyte abnormalities. Tub bathing causes less body temperature variability than sponge bathing and can be performed as infrequently as once every four days without increasing bacterial colonization of the skin. Topical emollients, particularly sunflower seed oil, appear to reduce the incidence of skin infections in premature neonates—but only in developing countries. In developed countries, studies indicate that topical petrolatum ointment increases the risk of candidemia and coagulase‐negative Staphylococcus infection in the preterm population, perhaps by creating a milieu similar to occlusive dressings. For preterm infants with catheters, povidone‐iodine and chlorhexidine are comparably effective at preventing catheter colonization. Further studies are necessary to examine the safety and efficacy of various skin care interventions in premature infants with an emphasis placed on subclassifying the patient population. In the interim, it may be beneficial to develop guidelines based on the current body of evidence. 相似文献

Summary: Skin care is essential for many patients wearing compression hosiery. However, skin care products may impact the elasticity of the stockings. Since a recommendation of skin care products would be of great value for the patients we have developed a method for testing the influence of creams and lotions on compression hosiery. Stockings manufactured from synthetic yarns are almost resistant towards the effects of the analyzed formulations while fabric containing natural rubber is heavily influenced by most of these products. Besides Paraffinum liquidum other ingredients have a negative impact on the elastic properties of natural rubber. With the help of this method we are able to select dermatological preparations which can be used without harming the delicate fabric of compression hosiery. 相似文献
