ABSTRACT
BACKGROUND: NB-UVB has long been the vitiligo management pillar with capability of achieving the main treatment outcomes; repigmentation and stabilization. Its stabilizing effect in dark skin has been debatable. However, randomized controlled trials regarding NB-UVB ability to control disease activity are lacking. PURPOSE: To assess stabilizing effect of NB-UVB in comparison to systemic corticosteroids, the mainstay in vitiligo stabilization, in skin photo-types (III-V). METHODS: This is a multicenter, placebo-controlled, randomized, prospective study. Eighty patients with active nonsegmental vitiligo (NSV) (Vitiligo disease activity (VIDA) ≥2) were randomized to either NB-UVB and placebo (NB-placebo) or NB-UVB and dexamethasone oral mini-pulse (OMP) therapy (NB-OMP) for 6 months. Sixty four patients completed the study, 34 in the NB-OMP group and 30 in the NB-placebo group. Patients were evaluated fortnightly according to presence or absence of symptoms/signs of activity. RESULTS: In spite of earlier control of disease activity observed in the NB-OMP group, it was comparable in both groups by the end of the study period. Disease activity prior to therapy, but not extent, was found to influence control of activity in both groups. Thus, NB-UVB is a safe sole therapeutic tool in vitiligo management. Not only does it efficiently achieve repigmentation, but also it is a comparable stabilizing tool for systemic corticosteroids in spite of slightly delayed control. CONCLUSION: NB-UVB is the only well-established vitiligo therapy that can be used solely whenever corticosteroids are contraindicated or immune-suppression is unjustified. Nonetheless, its combination with corticosteroids expedites response and improves compliance.

INTRODUCTION: Psoriasis is a chronic, multisystem, inflammatory, disfiguring disease with a high negative impact on quality of life due to comorbid psychological, organic, and sexual consequences. AIM: To evaluate the psychopathological and sexual aspects of psoriasis vulgaris in patients and their partners compared to healthy controls. METHODS: In the current comparative cross-sectional study, the sample included 220 psoriasis vulgaris patients (110 males and 110 females), their consenting partners, and 220 age- and sex-matched healthy controls. All participants were evaluated for depression and anxiety using the Hospital Anxiety and Depression Scale and for low self-esteem using the Rosenberg's Self-Esteem Questionnaire. Sexual function was assessed in females using the Female Sexual Function Index questionnaire and in males using the International Index of Erectile Function and its abbreviated 5-item version. For male patients suffering from erectile dysfunction, hormonal assessment and penile duplex ultrasound were added. MAIN OUTCOME MEASURE: The main outcome measures were frequency of depression, anxiety, low self-esteem, and sexual dysfunction in psoriasis vulgaris patients, partners, and controls; the domains of sexual function affected in the studied groups; and the etiology of erectile dysfunction in affected psoriatic males. RESULTS: Frequency of depression, anxiety, and low self-esteem were significantly higher in psoriasis patients of both sexes compared with controls. Sexual dysfunction followed the same trend of being significantly higher in cases when compared to controls. Females had a significantly higher frequency of sexual dysfunction than males. Sexual dysfunction in both sexes involved multiple domains of the sexual response cycle, with depression and genital affection by psoriasis being risk factors in both sexes and disease severity being an additional risk factor in females. Erectile dysfunction was mainly psychogenic in origin in male patients. CLINICAL IMPLICATIONS: Assessment of psychopathological and sexual comorbidities in psoriasis patients and partners should be an integral part of the management plan and should be added to the guidelines of the disease. STRENGTH & LIMITATIONS: This study is of sufficient power to draw solid conclusions. Assessment of the partners and determination of the sexual domains affected by the disease and nature of erectile dysfunction in males are points of novelty. The cross-sectional design is a limitation of the study. CONCLUSION: Psoriatic patients of both sexes and their partners suffer from a high burden of psychopathological and sexual consequences that are related to disease distribution and severity.

BACKGROUND: Chronic hepatitis C (CHC) infection causes a wide range of immune mediated hepatic and extrahepatic manifestations. Cutaneous manifestations constitute a major portion of the latter group. Host immune response to the virus - particularly regulatory T lymphocytes - is important in determining the outcome of the infection and the possibility of extrahepatic manifestations. The present study aims to investigate the relationship between immune-mediated cutaneous manifestations of CHC infection and the frequency of CD4+CD25 high FOXP3+ T regulatory lymphocytes. We also investigated the relationships to viral load and hepatic conditions. METHODS: A total of 58 CHC patients (30 had cutaneous manifestations and 28 did not) and 30 healthy HCV free subjects were enrolled in this study. The frequency of CD4+CD25 high FOXP3+ Treg cells was measured in the peripheral blood of all participants. Additionally, serum ALT, RNA viral load, and hepatic ultrasonographic studies were performed for all patients. RESULTS: Skin manifestations were dominated by small vessel vasculitis and to a lesser extent lichen planus. Treg cell frequency was significantly lower in CHC patients with skin manifestations compared to those without. Chronic hepatic insult was significantly more common among patients with skin manifestations, although serum ALT levels were significantly lower in this group. Treg frequencies did not correlate to either ALT level or viral load. CONCLUSIONS: HCV-associated skin lesions are associated with low frequency of Treg cells. They are not related to liver enzymes or viral load; however, they are associated with a more advanced gross liver insult.

BACKGROUND: Repigmentation remains the primary target in vitiligo treatment. Melanocyte transfer procedures are often required for repigmenting stable, resistant vitiligo lesions necessitating procedural optimization and comparative evaluation. In the current study, we aimed to assess the additive value of weekly transverse needling sessions after mini-punch grafting for repigmenting stable non-segmental vitiligo lesions versus either procedure alone. METHODS: Eighty lesions, included in 20 stable non-segmental vitiligo patients, were randomly allocated to each of the three treatment groups (line-1, mini-punch grafting; line-2, needling; and line-3, combined grafting and needling) and to a fourth control group receiving non-procedural treatment (line-4). Oral mini-pulse steroids and narrow-band ultraviolet-B sessions were administered to all patients for 3 months before and 6 months after the interventions. The extent of repigmentation was assessed using planimetry. Secondary outcomes were the time to first repigmentation response, cosmetic matching, and patient satisfaction. Blinding and allocation concealment were not feasible owing to the intervention nature and within subject design. RESULTS: Mini-punch grafting followed by weekly needling for 6 months achieved the fastest response and highest extent of repigmentation. Mini-punch grafts and transverse needling alone provided better results than the control group. No steroid-associated side effects were reported. CONCLUSION: Weekly needling sessions after mini-punch grafting hastened and improved the repigmentation extent of stable, resistant, non-segmental vitiligo lesions and should be considered during treatment planning.
ABSTRACT
New indications are being reported for intradermal botulinum toxin type A (BTX-A) owing to its anti-inflammatory and antipruritic actions. Its successful use for dyshidrotic hand eczema and lichen simplex has been reported in a few cases, while its utility in dry palmar eczema not associated with hyperhidrosis has not yet been investigated. The aim of this study was the assessment of the additive efficacy and tolerability of BTX-A in chronic dry palmar eczema. This prospective non-randomized side-by-side comparative study included 30 cases of chronic bilateral dry palmar eczema with no associated hyperhidrosis. Combined emollients and topical mid-potency steroid on one side were compared with an additive 100 units of intradermal BTX-A on the other side for efficacy and tolerability using both patient- and physician-oriented scores over a period of 6 months. Timing and extent of improvement and relapse were recorded on both sides, together with the frequency of development of side-effects. Both lines were effective and well tolerated, with significantly greater reduction of symptom and sign scores and higher overall patient satisfaction on the side receiving BTX-A, an effect which lasted for a significantly longer duration on this side (4 months) as compared with the other side (1 month). In conclusion, intradermal BTX-A at a dose of 100 units/palm is beneficial and well tolerated in chronic dry palmar eczema. Compared with topical steroid and emollients alone, its addition yielded superior efficacy that was longer lasting and more satisfactory to the patients, while exerting a steroid-sparing effect.

BACKGROUND: Psoriasis is a chronic inflammatory multisystem disease with imbalance between the Th17 and T regulatory sub-populations. CD200/CD200R is an anti-inflammatory/immune-suppressive axis that might contribute to its pathogenesis given its relation to the Tregs induction. The current study aimed to investigate the status of the CD200/CD200R axis in the blood of psoriasis vulgaris patients versus healthy controls. METHODS: In this comparative cross sectional study, the blood levels of sCD200 and CD200R levels were measured in 25 psoriasis vulgaris patients and an age and sex matched 25 healthy controls using ELISA and flow-cytometry respectively. Their levels were tested for correlation to disease severity. RESULTS: sCD200 was significantly higher while CD200R was significantly lower in psoriasis vulgaris patients than in controls. They did not correlate to each other or to psoriasis severity although they differed significantly among cases of different severities. CONCLUSION: Aberrant expression of CD200/CD200R might play a role in psoriasis vulgaris pathophysiology and disease severity. It might constitute a future target of therapy, but cannot be used as a marker of disease severity.

Injection of platelet concentrates for the treatment of aging skin has gained popularity. The objective was to systematically assess the evidence regarding the safety and effectiveness of platelet-rich plasma (PRP) for reducing the visible signs of aging. Cochrane Library, MEDLINE (PubMed), EMBASE, and Scopus were searched from inception to March 2019 for prospective trials and case series assessing PRP for skin aging in 10 or more patients. Twenty-four studies, including 8 randomized controlled trials (RCTs), representing 480 total patients receiving PRP, were included. Based on physician global assessment, injection PRP monotherapy was shown to at least temporarily induce modest improvement in facial skin appearance, texture, and lines. Periorbital fine lines and pigmentation may also benefit. Adjuvant PRP accelerated healing after fractional laser resurfacing. Although the degree of improvement was typically less than 50%, patients generally reported high satisfaction. It was limited by heterogeneity in PRP preparation and administration, and lack of standardization in outcome measures. PRP injections are safe and may be modestly beneficial for aging skin. The evidence is most convincing for improvement of facial skin texture. The persistence of these effects is not known. More high-quality trials with sufficient follow-up are needed to optimize treatment regimens.
