RESUMO

Generalized lymphatic anomaly (GLA), previously known as lymphangiomatosis, is a rare developmental disease characterized by abnormal proliferation of lymphatic vascular structures that may involve the dermis, soft tissue, bone, and visceral parenchyma. Being an uncommon condition and the lack of specific symptoms often result in a delayed diagnosis or even misdiagnosis, which, in addition to its progressive nature, can lead to dysfunction of vital organs, and ultimately, a poor prognosis. In this report, we present a unique case of GLA in an upper Egyptian female child. Increasing awareness of the possible phenotypic presentations of such anomalies can lead to early diagnosis and possibly more effective management before significant organ damage ensues.

RESUMO

BACKGROUND: Acne vulgaris is a common skin problem that may result in significant scarring and systemic comorbidities. Adverse effects and increasing resistance to available treatments urge the development of new therapeutics. Topical vitamin D analogues have been successfully used in psoriasis; however, the efficacy and safety of calcipotriol as a potential topical treatment of acne is yet to be established. OBJECTIVES: To evaluate the efficacy and safety of calcipotriol in treating acne compared with adapalene and placebo. METHODS: Sixty patients with acne were included and randomly divided into two groups of 30 patients each. Group I participants were treated by daily application of calcipotriol 0.005% cream on one facial side vs. placebo (petrolatum) over the other side. Group II were treated by daily application of adapalene 0.1% gel over one facial side vs. calcipotriol on the other. Therapeutic response was evaluated using the Japanese Acne Grading System (JAGS) and through photographic evaluation using Mean Improvement Score by Physician. RESULTS: Adapalene-treated skin gave the greatest improvement and the highest patient satisfaction compared with skin treated with calcipotriol or placebo (P = 0.001). Nonetheless, the calcipotriol-treated side showed a significantly greater reduction in post-treatment JAGS score and much greater satisfaction than placebo. As treatment continued, improved tolerability to calcipotriol was noted, with comparable side-effects between the three study arms. CONCLUSIONS: Calcipotriol seems to be a promising new safe topical therapeutic option for acne. However, adapalene is still superior in efficacy, tolerability and patient satisfaction.

RESUMO

Alopecia areata (AA) is a common cause of hair loss with no available universally successful treatment. Thus, new innovative treatments are urgently needed. This research aimed to evaluate the effectiveness of fractional carbon dioxide laser (FCL) alone or combined with triamcinolone acetonide (TA) solution, platelet-rich plasma (PRP), or vitamin D3 solution in treating AA. Sixty-four AA patients with 185 lesions were recruited and divided into four treatment groups. All patients received FCL either alone (group A, n = 19) or followed by topical TA (group B, n = 16) or PRP (group C, n = 15), or vitamin D3 solution (group D, n = 14). The response was assessed using Alopecia Areata Severity Index (AASI), MacDonald Hull and Norris grading, and trichoscopy. Histopathological features and immunohistochemical decorin expression were studied. All groups showed significant improvement in AASI compared to the baseline, with insignificant differences between them. Post-treatment, trichoscopic features of disease activity significantly decreased in all groups. Compared to control biopsies, both anagen follicles and decorin expression were significantly decreased in all pretreatment specimens. After treatment, all groups showed significantly increased anagen follicles and decorin expression compared to the baseline. Accordingly, FCL is an effective treatment for AA alone or combined with TA, PRP, or vitamin D3 solution. In AA, Decorin expression was downregulated, while enhanced expression following successful treatment occurred. This suggests the role of decorin in AA pathogenesis. However, further research is still recommended to clarify the exact role of decorin in AA pathogenesis and to investigate the therapeutic benefits of decorin-based therapy.

RESUMO

Background: Melasma is a common acquired facial hyperpigmented skin disorder. Platelet-rich plasma (PRP) is autologous plasma containing higher than normal platelets concentrations. Recently, PRP has been used as a therapeutic modality in melasma with significant clinical improvement, possibly due to its abundant contents of growth factors such as TGF-ß. The latter represents a natural multifunctional polypeptide that negatively regulates melanocyte differentiation and therefore reduces skin hyperpigmentation. To date, the expression pattern of TGF-ß protein in skin of melasma patients following PRP injection is unknown. Here we hypothesize that "injection of PRP in the lesional skin of melasma patients is associated with alterations of TGF-ß protein expression".Patients and Methods: The study included 20 adult patients with melasma. Autologous PRP was delivered into the lesional skin either through microneedling or as intradermal microinjections. TGF-ß protein expression was immunohistochemically examined in the perilesional and lesional skins before and after PRP treatment and in the healthy skins of nine volunteers (control group).Results: TGF-ß protein was expressed within the epidermis, dermal adnexal structures, vascular endothelium, nerves and arrector pili muscle fibers of the healthy skins (control group), perilesional and lesional skins of melasma patients before and after treatment with PRP. Before treatment with PRP, the expression ofTGF-ß protein in the lesional (1.26 ± 0.41) and perilesional (1.68 ± 0.51) skins of melasma patients were significantly lower than that in the healthy skins (2.26 ± 0.37, p value<.05). After treatment with PRP, the expression of TGF-ß protein was significantly increased in the lesional (2.15 ± 0.44) skin of melasma patients.Conclusions: Our study provides the first indication about increased TGF-ß protein expression in skin of melasma patients after PRP treatment. The alterations of TGF-ß protein in skin of melasma patients not only support its roles in the development of this condition but also have some therapeutic ramifications.

RESUMO

Background: Melasma is a cosmetically disfiguring disorder of facial pigmentation. Objectives: We evaluated the value of platelet-rich plasma (PRP) in the treatment of melasma using two different delivery techniques: microneedling using dermapen versus microinjections using mesoneedles. Patients and methods: Twenty-three adult Egyptian melasma patients were enrolled. Wood's light was used to determine the histological type of melasma. Autologous PRP was delivered into the lesional melasma skins through microneedling with dermapen on the right side of the face and intradermal microinjections using mesoneedles on the left side of the face (for each patient). The treatment was done regularly (three sessions, each month). The response to PRP therapy was measured using melasma area and severity index (MASI) and modified melasma area and severity index (mMASI) that were calculated before and after three treatment sessions. Hemi-MASI was used to compare the effectiveness of the two delivery techniques. Results: Following PRP treatment, MASI and mMASI scores decreased significantly from 11.86 ± 5.25 to 6.96 ± 4.82, and from 5.71 ± 2.56 to 2.90 ± 2.05, respectively (p < .000,). A statistically significant decrease was noted in the hemi-MASI score on each side of the face following PRP treatment (p < .000), but there was no significant difference in comparing both sides. Conclusions: Our study provides the first indication about the value of PRP as a useful and new therapeutic option in melasma. Moreover, our study was the first to compare PRP delivery through microneedling versus microinjections.
