The patient visited our department because the clinical manifestations of mandibular acne did not improve. At the time of initial examination, telangiectasia (TE), post-inflammatory erythema (PIE), post-inflammatory hyperpigmentation (PIH), atrophic scars (ASs), and a hypertrophic scar (HS) with induration were observed on the right neck. We diagnosed this as an acne vulgaris complication. HS lesions were topically treated by injecting triamcinolone acetonide, and the patient was prescribed 8.1 g/day of oral Saireito (Japanese herb). Adapalene benzoyl peroxide gel and topical tacrolimus hydrate ointment were used to treat PIE and TE. Both HSs and PIE improved;however, TE and AS did not improve. Currently, the patient is under observation. We consider this to be a very rare concurrent occurrence of diverse complications of acne vulgaris, and present the following case study.展开更多

This study aimed to determine whether dermatologists’ guidance on appropriate skincare for skin symptoms such as post-inflammatory erythema and post-inflammatory hyperpigmentation (PIH), which are not covered by acne treatment, leads to an improvement in patients’ skin condition and patient satisfaction. Japanese women who had completed standard treatment for acne vulgaris and those with mild symptoms not requiring treatment were included in the study. The participants received instructions about skin care at the beginning of the study, which they continued to apply for 6 weeks. At the start and end of the study, participants were examined by a dermatologist;afterward, skin measurements, including skin color, skin surface lipid content, and image analysis by VISIA<sup>®</sup> Evolution, analysis of stratum corneum obtained from the skin surface, and Skindex-16 questionnaire for assessing quality of life (QOL), were performed. The following showed significant improvements: PIH score, number of inflammatory acne lesions, and number of non-inflammatory acne lesions observed via skin examination;skin surface lipid content and values of L* and a* obtained via instrumental measurement;n number of pore, texture, red spot, and pigmented spot obtained via by image analysis;and degree of multilayer exfoliation and interleukin-1α determined by analysis of epidermal stratum corneum. QOL measurement using Skindex-16 also improved significantly. Appropriate skin care guidance following standard acne vulgaris treatment is helpful in achieving patients’ treatment goals. .展开更多

Alternative solutions to acne treatment were instigated by antibiotic resistance despite of its extensive use. Purified bee venom （PBV） has been proposed as a promising candidate for that purpose. The present study was designed to confirm the antibacterial effect of PBV and access the efficacy of cosmetics containing PBV in subjects with acne vulgaris. METHODS： The skin bacterium Propionibacterium acnes was incubated with PBV at various concentrations and bacterial growth was evaluated using the colony forming unit （CFU） assay. The mechanism of PBV employed in killing P. acnes was examined by scanning electron microscopy （SEM） and transmission electron microscopy （TEM）. In addition, a total of 12 subjects were randomized in a double-blind, controlled trial to receive either cosmetics containing PBV or cosmetics without PBV for two weeks. Evaluations included lesion counts and skin microorganism. RESULTS： PBV exhibited antimicrobial activity in a concentration-dependent manner, reducing the number of P. acnes CFU by approximately 6 logs at a concentration of 0.5 mg. When PBV concentration was higher than 1.0 mg, no P. acnes colonies were spotted on an agar. TEM and SEM of untreated P. acnes illustrated the normal pleomorphic structure, whereas the PBV- treated bacterium lost the integrity of surface architecture. Significant difference （P=0.027） in the grading levels based on numbers of lesion counts for inflammatory and noninflammatory was observed in favour of the PBV group compared with the control group. In terms of average decrement of skin microorganism, subjects receiving cosmetics containing PBV experienced a significant 57.5% decrease of adenosine triphosphate levels, whereas participants receiving cosmetics without PBV experienced a nonsignificant decrease of 4.7%. CONCLUSION： These results show that the in vitro actions of antimicrobial activity of PBV were translated in vivo. Cosmetics containing PBV provided a certain degree of efficacy in terms of lesion counts and skin microorganism concentration compared with cosmetics without PBV in subjects with acne vulgaris. PBV may be a good candidate compound for developing therapeutic drua for the treatment of acne vulaaris.展开更多

The needles are inserted into the skin by a specially designed electronically controlled, smooth motion motor minimizing patient discomfort. RF emission delivered over the whole dermal portion of the needle allows effective coagulation resulting in minimal or no bleeding, together with bulk volumetric heating. Study Design/Materials and Methods: The study included 20 patients, treated for depressed acne scars using the IntensifTM?Microneedles handpiece (EndyMed PRO Platform System, EndyMed Medical, Caesarea, Israel). The degree of clinical improvement was assessed by the global aesthetic improvement scale (GAIS) and subjects satisfaction by post treatment questionnaires. Results: The number of treatments per patient varied between 1 and 6 (average 3.3 treatments per patient). Eleven patients (55%) reported none to minimal pain, six (30%) moderate discomfort and only three (15%) reported significant pain. Objective evaluation of the improvement by a board certified dermatologist showed improvement in 95% of patients. 25% showed excellent improvement, 50% experienced good improvement, and the 20% showed minimal improvement. One patient showed no improvement. Conclusions: The presented results show that the tested electronically controlled motorized insertion, non-insulated microneedle treatment technology provides a minimal discomfort, minimal downtime, effective and safe treatment for depressed acne scars.展开更多

文摘Background: The microneedle fractional RF handpiece used in our study (Intensif Handpiece, EndyMed Medical, Caesarea, Israel) is a novel handpiece that uses a tip with 25 non-insulated, gold plated microneedle electrodes. The needles are inserted into the skin by a specially designed electronically controlled, smooth motion motor minimizing patient discomfort. RF emission delivered over the whole dermal portion of the needle allows effective coagulation resulting in minimal or no bleeding, together with bulk volumetric heating. Study Design/Materials and Methods: The study included 20 patients, treated for depressed acne scars using the IntensifTM?Microneedles handpiece (EndyMed PRO Platform System, EndyMed Medical, Caesarea, Israel). The degree of clinical improvement was assessed by the global aesthetic improvement scale (GAIS) and subjects satisfaction by post treatment questionnaires. Results: The number of treatments per patient varied between 1 and 6 (average 3.3 treatments per patient). Eleven patients (55%) reported none to minimal pain, six (30%) moderate discomfort and only three (15%) reported significant pain. Objective evaluation of the improvement by a board certified dermatologist showed improvement in 95% of patients. 25% showed excellent improvement, 50% experienced good improvement, and the 20% showed minimal improvement. One patient showed no improvement. Conclusions: The presented results show that the tested electronically controlled motorized insertion, non-insulated microneedle treatment technology provides a minimal discomfort, minimal downtime, effective and safe treatment for depressed acne scars.

文摘Objective:Propionibacterium acnes(P.acnes)plays an important role in the development of acne,an inflammatory skin disease with a high-incidence.In this study,we used high-throughput RNA sequencing(RNA-seq)to reveal the anti-inflammatory mechanism of baicalin on P.acnes-induced acne in rabbits.Methods:The Kligman method was used to induce acne in the ears of New Zealand rabbits.The effect of baicalin on the acne model was evaluated by the number of acne lesions and hematoxylin and eosin(H&E)staining of acne tissues.Enzyme-linked immunoabsorbent assay was used to measure the protein expression levels of tumor necrosis factor a(TNFA),interleukin-1 b(IL1B),IL6,and IL8 in the serum of rabbits.RNA-seq was performed to investigate the mechanism of anti-inflammatory activities of baicalin on acne.Immunohistochemical analysis and Western blot were used to validate the expression levels of related proteins in acne tissues.Results:Baicalin treatment significantly reduced the number of acne lesions and lesions of the ear as well as levels of serum inflammatory cytokines.RNA-seq data showed that baicalin treatment globally suppressed inflammation,especially the TNF signaling pathway and Staphylococcus aureus infection pathway,in the rabbit acne model.Conclusion: Baicalin effectively ameliorates P. acnes-induced acne in rabbits by suppressingthe inflammatory response in rabbits.
文摘BACKGROUND Synovitis,acne,pustulosis,hyperostosis,and osteitis(SAPHO)syndrome is a rare autoinflammatory disease for which clinical treatment has not been standardized.Janus kinase(JAK)inhibitors represent a novel therapeutic option for rheumatoid arthritis,psoriatic arthritis,and some other autoinflammatory diseases.However,the clinical utility of JAK inhibitors in treating SAPHO syndrome has not been thoroughly investigated.In this study,we describe a patient with SAPHO syndrome who failed to respond to conventional treatment but demonstrated a remarkable and rapid response to the JAK inhibitor tofacitinib.CASE SUMMARY A 62-year-old female patient presented with swelling and pain at the sternoclavicular joints,back pain that limited her activities,arthralgia in the right knee,and cutaneous lesions.Her symptoms were unresponsive to nonsteroidal anti-inflammatory drugs,disease-modifying antirheumatic drugs,Tripterygium wilfordii hook f,and bisphosphonates.SAPHO syndrome was diagnosed in accordance with dermatological and osteoarticular manifestations and abnormal inflammatory factors.Multiple image studies have illustrated bone lesions and pathological fractures of vertebral bodies.Oral treatment with tofacitinib at 5 mg twice daily with methotrexate and bisphosphonates was initiated.The patient reported that her pain symptoms were relieved after 3 d and her cutaneous lesions were reduced after 4 wk of treatment.Vertebral lesions were improved after 6 mo on tofacitinib.No serious adverse effects were noted.CONCLUSION JAK inhibitor therapy may be a promising strategy to treat SAPHO syndrome.
