Does chronic urticaria affect quality of sleep and quality of life?

Background: Urticaria affects a wide range of daily activities and social relationships. It has a severe impact on quality of life (QOL) and causes psychological problems. Objective: was to assess the impact of chronic urticaria (CU) on quality of sleep, the levels of depression, anxiety, QOL and their interaction with each other and their relation to disease related factors. Patients and methods: The study included 25 patients with CU and 25 healthy controls. Urticaria Activity Score (UAS) was used for objective evaluation of the intensity of urticaria. Patients completed a 10-cm visual analogue score (VAS) indicating the overall severity of their itching over the previous 2 weeks. The Dermatology Life Quality Index (DLQI) was used to evaluate patients' QOL. Patients were also assessed for anxiety and depression with the Hospital Anxiety and Depression Scale (HADS). Pittsburgh Sleep Quality Index (PSQI) was used for evaluation of sleep quality and sleep disturbances. Results: In our CU patients the mean of UAS7 score was 39.72 ± 2.76 and the mean of VAS score was 28 ± 1.34. The mean of DLQI score was 24.8 ± 4.37 indicating severe impact of QOL. CU patients had higher total HADS score when compared to controls; 72% of the patients had depression and 92% had anxiety. By using PSQI, CU patients had significantly longer sleep latency onset, shorter total sleep duration, lower sleep efficiency and higher PSQI scores compared to controls. Conclusion: CU highly affects the QOL of patients and is associated with higher levels of anxiety, depression and poor sleep quality.

Topical Ectoin Versus Topical Dexpanthenol for Managing Acute Radiodermatitis Associated With Breast Cancer Radiotherapy: A Randomized Double-Blind Study.

Background: Radiodermatitis is a common side effect of breast cancer radiotherapy; however, there is no current consensus regarding an effective standard therapy. Objective: To evaluate the efficacy of topical ectoin versus dexpanthenol in the management of acute radiodermatitis after breast cancer radiotherapy. Methods: Fifty patients randomly used dexpanthenol 5% cream (25 patients), or ectoin 7% cream (25 patients), applied twice daily to the irradiated area during and for 2 weeks after radiotherapy. The study was stratified by the radiotherapy schedule and was double-blind. Radiodermatitis grade, radiation-associated symptoms, and adverse events were assessed weekly during radiotherapy and 2 weeks thereafter. Skin-related quality of life (QOL) scores were measured using the Skindex-16 questionnaire. Results: Both agents were effective in preventing severe radiodermatitis (≥G3). Ectoin had a lower radiodermatitis grade level than dexpanthenol, with a significant difference at week 2 (P = 0.008). Radiation-associated pain (P = 0.003) and itching (P = 0.001) were lower with ectoin than dexpanthenol. Side effects were not significantly different between the 2 treatments (P = 0.107). Ectoin showed less QOL impairment than dexpanthenol. The radiation schedule was an independent predictor for radiodermatitis persistence. Conclusion: Ectoin showed some clinical benefit over dexpanthenol in improving radiation dermatitis and the radiation schedule is a predictor of radiodermatitis persistence.

Serum pentraxin 3 in systemic lupus erythematosus: A potential indicator of cutaneous disease activity.

BACKGROUND: Although skin manifestations are common in systemic lupus erythematosus (SLE), there is still a lack of a diagnostic marker for cutaneous involvement. Pentraxin3 (PTX3) has been studied in SLE patients; however, it has not been investigated in relation to cutaneous manifestations. OBJECTIVE: To assess the serum PTX3 level in SLE patients, and to investigate its relationship with disease activity as well as with variable skin manifestations. PATIENTS AND METHODS: Thirty-four patients with SLE (17 patients with skin manifestations and 17 without) and 30 healthy subjects were included in the study. Patients were evaluated clinically for systemic and skin manifestations of SLE. Systemic Lupus Erythematosus Disease Activity Index (SLEDAI-2k) and Cutaneous Lupus Erythematosus Activity and Severity Index (CLASI) scores were calculated. Serum level of PTX3 was measured in patients and controls using ELISA. RESULTS: Higher serum PTX3 level was found in SLE patients compared to controls (p < 0.001). Patients with skin manifestations showed higher SLEDAI-2k scores and had higher PTX3 level compared to those without skin manifestations (p = 0.015 and p < 0.001, respectively). PTX3 showed higher levels in association with malar rash (p < 0.001), mucosal ulcers (p < 0.001), alopecia (p < 0.001), and purpuric eruption (p = 0.002). Moreover, PTX3 level positively correlated with CLASI scores (p < 0.001). CONCLUSION: Our results reinforce the important role of Pentraxin3 in SLE patients with skin manifestations, and it may be considered an interesting biomarker for the pattern and extent of cutaneous involvement in SLE.

Efficacy of Cryotherapy Combined With Intralesional Purified Protein Derivative (PPD) Versus Intralesional PPD Monotherapy in the Treatment of Multiple Common Warts.

INTRODUCTION: Intralesional antigen immunotherapy represents a promising therapeutic approach for the treatment of different types of warts, particularly if multiple and/or recalcitrant. AIM: to investigate the efficacy and safety of combined cryotherapy with intralesional purified protein derivative (PPD) immunotherapy in the treatment of multiple common warts. METHODS: Fifty patients were randomly divided into two groups (25 patients each): Group A: receiving intralesional PPD immunotherapy for the largest wart, while group B: receiving cryotherapy for all warts plus intralesional PPD for the largest wart. Treatments were performed every 2 weeks for a maximum of four sessions. Photographs were taken at baseline and at each visit and clinical response was evaluated by the reduction in number and size of warts. Adverse effects were recorded. RESULTS: There was a significant reduction in size and number of warts in both groups (P < .001), with no significant difference between the two groups. Complete clearance of the lesions was observed in 48% of patients in group A and 44% in group B (P = .39). Higher rates of near complete/complete response were achieved after fewer sessions (2, 3 sessions) in group B (P = .002). Blistering was common after cryotherapy. Higher rate of hypopigmentation was noticed after combined treatment than after PPD monotherapy (56%, 8% respectively; P < .001), which resolved gradually. CONCLUSION: Both intralesional PPD alone and combined cryotherapy with PPD are safe and effective in clearing of common warts. Cryotherapy may be a successful adjunct to intralesional PPD immunotherapy that helps in reducing the number of treatment sessions.The study protocol was registered at ClinicalTrials.gov with ID: NCT04288817.

Tailoring of Retinyl Palmitate-Based Ethosomal Hydrogel as a Novel Nanoplatform for Acne Vulgaris Management: Fabrication, Optimization, and Clinical Evaluation Employing a Split-Face Comparative Study.

AIM: Retinyl palmitate (RP), the most stable vitamin A derivative, is used to treat photoaging and other skin disorders. The need to minimize the adverse effects of topical drug administration has led to an enhanced interest in loading RP on ethosomes for topical drug delivery. The aim of the current study was to prepare and compare the performance of RP decorated ethosomal hydrogel with tretinoin cream in the treatment of acne vulgaris as an approach to improve drug efficacy and decrease its side effects. METHODS: RP-loaded ethosomes were prepared using the injection sonication technique. A Box-Behnken design using Design Expert® software was used for the optimization of formulation variables. Particle size, zeta potential (ZP), entrapment efficiency percent (EE%), % drug release, and permeation over 24 h of different formulations were determined. The optimal formulation was incorporated into a hydrogel. Finally, the efficacy and tolerability of the optimized RP ethosomal hydrogel were clinically evaluated for acne treatment using a split-face comparative clinical study. RESULTS: The optimized ethosomal RP showed particle size of 195.8±5.45 nm, ZP of -62.1±2.85 mV, EE% of 92.63±4.33%, drug release % of 96.63±6.81%, and drug permeation % of 85.98 ±4.79%. Both the optimized RP ethosomal hydrogel and tretinoin effectively reduced all types of acne lesions (inflammatory, non-inflammatory, and total lesions). However, RP resulted in significantly lower non-inflammatory and total acne lesion count than the marketed tretinoin formulation. Besides, RP-loaded ethosomes showed significantly improved tolerability compared to marketed tretinoin with no or minimal skin irritation symptoms. CONCLUSION: RP ethosomal hydrogel is considerably effective in controlling acne vulgaris with excellent skin tolerability. Therefore, it represents an interesting alternative to conventional marketed tretinoin formulation for topical acne treatment.

Efficacy of stem cell-conditioned medium vs. platelet-rich plasma as an adjuvant to ablative fractional CO2 laser resurfacing for atrophic post-acne scars: a split-face clinical trial.

OBJECTIVES: To explore the impact of using topical stem cell-conditioned medium (SC-CM) after fractional carbon dioxide laser (FCL) vs. combined FCL and platelet-rich plasma (PRP) or FCL alone in treatment of atrophic acne scars. METHODS: Thirty-three patients were randomly divided into two split-face groups. Group I (n = 17) received FCL plus topical SC-CM on one side or FCL plus saline on the other. Group II (n = 16) received FCL plus topical PRP or SC-CM. All patients had three monthly sessions. Clinical assessment was done at each visit, with a final assessment after 3 months. Skin biopsies were obtained for histological and quantitative molecular analysis after treatment. RESULTS: No significant difference in clinical improvement of acne scars was observed between the FCL/SC-CM and FCL only sides (p = .63), while better and faster improvement was detected on FCL/PRP side compared to FCL/SC-CM side (p = .006). There was no significant difference in downtime or adverse effects between the treated sides in either group. Dermal collagen was increased and procollagen type I gene was upregulated in both FCL/PRP and FCL/SC-CM sides compared to FCL only sides (p = .001 and p = .041, respectively). CONCLUSIONS: Topical SC-CM could potentially enhance the efficacy of FCL. However, PRP seems to be a better alternative.

Cutaneous JAK Expression in Vitiligo.

BACKGROUND: The Janus kinase-signal transducer and activator of transcription signaling pathway has been suggested as a promising therapeutic target in vitiligo. However, limited data is available on the cutaneous expression of JAK in vitiligo. AIM: This study is designed to analyze the cutaneous expression patterns of JAK1, 2, and 3 in vitiligo and investigate their relation to the disease clinical parameters. METHODS: This case-control study recruited 24 patients having active vitiligo and 20 age, sex, and skin type-matched healthy volunteers. Skin biopsies were obtained from patients (lesional, perilesional and nonlesional) and controls for assessment of JAK1, 2, and 3 expression using RT-PCR. RESULTS: JAK1 and JAK3 were overexpressed in patients' skin compared to control skin and showed a stepwise pattern of upregulation from control to nonlesional, perilesional and lesional skin. However, JAK3 showed much stronger expression. In contrast JAK2 expression showed no significant difference in any of lesional, perilesional or nonlesional skin compared to control skin. JAK1 and JAK3 expression levels showed no correlation with neither the disease activity nor severity. CONCLUSION: JAK1 and more prominently JAK3 are upregulated in vitiliginous skin and possibly contribute to the pathogenesis of the disease. Accordingly, selective JAK3/1 inhibition may provide a favorable therapeutic opportunity for vitiligo patients.This study is registered on the ClinicalTrials.gov Identifier: NCT03185312.

Efficacy of Intralesional Cryosurgery in the Treatment of Multiple Extragenital Cutaneous Warts: A Randomized Controlled Study.

BACKGROUND: The efficacy of intralesional (IL) cryosurgery in the treatment of cutaneous warts has not been previously studied. OBJECTIVE: To compare the efficacy and safety of IL cryosurgery versus electrosurgery in multiple extragenital warts and investigate their effect on serum interleukin (IL)-12 and interferon-gamma (IFN-γ). MATERIALS AND METHODS: Thirty-one patients were included; 18 received IL cryosurgery, and 13 had electrosurgery. Treatment was performed for the largest or few (2-3) small warts (target) until cleared, leaving the remaining (distant) warts untreated. Clinical response of the target and distant warts and adverse effects were evaluated. Serum IL-12 and IFN-γ levels were assessed before and after treatment. RESULTS: All patients had complete clearing of the treated wart in both groups. IL cryosurgery was well tolerated; infection, ulceration, and recurrence occurred only with electrosurgery. Complete/near-complete resolution of the distant untreated warts was seen in 33.3% versus none of patients in the IL cryosurgery and electrosurgery groups, respectively (p = .003). Furthermore, IL-12 and IFN-γ levels showed a tendency to increase after IL cryosurgery, and their increase correlated with distant wart response. CONCLUSION: Intralesional cryosurgery is effective not only in clearing treated warts but also resolving untreated warts and possibly enhances human papillomavirus-directed immune response.

Intralesional vitamin D3 versus intralesional purified protein derivative in treatment of multiple warts: A comparative clinical and immunological study.

Intralesional (IL) vitamin D3 is an emerging treatment for cutaneous warts. However, its effectiveness and exact mechanism is not fully evaluated. We aimed to compare the efficacy and safety of IL purified protein derivative (PPD) and IL vitamin D3 in multiple warts and to investigate their systemic effect clinically and immunologically. Forty-five patients with multiple extragenital warts were treated with IL-PPD (22 patients) or IL vitamin D3 injection (23 patients) for a maximum of three sessions at 3 week intervals. Decrease in size and number of warts and adverse effects were evaluated. Serum interleukin-12 (IL-12) and interferon-gamma (IFN-γ) levels were measured before and 3 weeks after the last session. Higher clearance rates for all warts were observed with IL-PPD compared to IL vitamin D (59.1% vs. 21.7% complete clearance, p < .001). Significant increase was found in both serum IL-12 and IFN-γ after PPD treatment (p = .034 and p = .04, respectively), but only IFN-γ after vitamin D3 treatment (p = 0.02). Both IL vitamin D3 and PPD showed positive results in treatment of multiple warts. However, PPD showed higher clinical efficacy and more increase in both IL-12 and IFN-γ levels.

Oxidative stress and psychiatric morbidity in patients with facial acne.

BACKGROUND: Acne vulgaris is a common cosmetic problem that is frequently associated with psychosocial disturbances as well as increased oxidative stress. However, oxidative stress and psychological aspects have been studied separately in acne. OBJECTIVE: To evaluate the relationships between oxidative stress, anxiety, depression, and quality of life in acne patients. METHODS: Sixty patients with facial acne and 40 age- and sex-matched healthy individuals were included in the study. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS), and quality of life (QoL) was measured by the Cardiff Acne Disability Index. Disease severity was assessed using the Combined Acne Severity Classification. The serum levels of zinc and malondialdehyde (MDA) and total antioxidant capacity (TAC) were measured in patients and healthy subjects. RESULTS: The mean HADS scores for anxiety and depression were higher in patients than controls (P<.001 for both). Acne patients showed higher serum MDA and lower TAC and serum zinc levels compared with control subjects (P=.019, P<.001, and P=.028, respectively). Anxiety and depression scores did not correlate with oxidative stress parameters. Patients with moderate/severe acne had worse anxiety scores than mild acne (P=.048), and higher anxiety scores were associated with poorer quality of life (r=.436, P=.001). CONCLUSION: Our results indicate that the high levels of anxiety and depression in patients with facial acne were not related to oxidative stress. Anxiety was more common than depression and was directly related to QoL impairment.

Suppression of transforming growth factor-beta1 expression in keloids after cryosurgery.

The biological mechanism underlying cryosurgical treatment of keloids remains unclear. Transforming growth factor-beta1 (TGF-ß1) has been implicated in the pathogenesis of keloids and was reported to be the target of several therapeutic modalities. However, the effect of cryosurgery on its expression in keloid tissue has not been yet investigated. In this study, 26 consecutive keloid patients were treated with cryosurgery for 2-6 sessions. Keloids were biopsied before starting cryosurgery and after two treatment sessions for the immunohistochemical evaluation of TGF-ß1 expression. The average volume reduction, after two treatment sessions (in 22 patients completing the study) was 68.77 ± 15.82%. Dermal overexpression of TGF-ß1 was demonstrated in all keloid specimens before treatment. Following therapy, significant reduction of that expression was detected in all keloid specimens (P = 0.016). In addition to attesting the clinical efficacy of cryosurgery, our findings indicate that cryosurgery effectively suppressed TGF-ß1 expression, possibly contributing to keloid regression.

A randomized, double-blind, placebo-controlled, crossover trial of "on-demand" tramadol for treatment of premature ejaculation.

OBJECTIVES: The objective of this study is to assess the dose-related effects of tramadol on a group of patients with premature ejaculation (PE). SUBJECTS AND METHODS: During the period of months between June 2010 and July 2012, 180 PE patients presented to outpatient clinic of our hospital. Patients were randomized in a 1:1:1 fashion to receive different sequences of the three medications: placebo, 50 mg of tramadol and 100 mg of tramadol. Every patient received 10 doses of each medication for 2 months. Intra-vaginal ejaculatory latency time (IELT) was recorded in seconds initially and for each arm. Successful treatment of PE is defined if IELT exceeded 120 s. Side-effects of medications were reported. RESULTS: Of patients enrolled, 125 (69.4%) continued the study. Patients' age range was 20-55 years with PE complaint of 1 to 10 years duration. Mean IELT was 72 at presentation, 82 for placebo, 150 for tramadol 50 mg, and 272 for tramadol 100 mg (P < 0.001 for all comparisons). PE was successfully treated in only 2.4% of patients with placebo, in contrast to 53.6% and 85.6% with 50 and 100 mg tramadol, respectively (P < 0.001 for all comparisons). On multivariate logistic regression analysis, baseline IELT was the only predictor of successful treatment of PE with both tramadol 50 mg (odds ratio [OR]: 1.05, 95% confidence interval [CI]: 1.03-1.07, P < 0.001) and tramadol 100 mg (OR: 1.07, 95% CI: 1.04-1.11, P < 0.001). Postmicturition dribble annoyed 12.8% of those who received 50 mg tramadol and 33.6% of those who received 100 mg tramadol (P < 0.001). Weak scanty ejaculation was the main complaint in 7.2% versus 21.6% of those using 50 and 100 mg tramadol, respectively (P = 0.002). Two patients discontinued tramadol 100 mg due to side-effects. CONCLUSION: Tramadol hydrochloride exhibits a significant dose-related efficacy and side-effects over placebo for treatment of PE.

Intralesional vs. contact cryosurgery in treatment of keloids: a clinical and immunohistochemical study.

BACKGROUND: Cryosurgery is a safe and effective treatment of keloids. Intralesional cryosurgery has been shown to bring about significant improvement in keloids. The histopathological and immunohistochemical changes in keloids following cryosurgery are not well-assessed. METHODS: Twenty-three patients with 66 keloids were treated with either the contact (cryoprobe) method or intralesional cryosurgery. Keloid specimens were obtained before treatment and after two sessions of treatment for evaluation of keloid pathology and immunohistochemical changes in expression of vascular endothelial growth factor (VEGF) and tenascin C induced by both cryosurgical techniques. RESULTS: A better therapeutic response was detected after intralesional cryosurgery (excellent response [ER], 87%) than contact cryosurgery (ER, 60%; P < 0.05). The intralesional technique achieved higher rates of flattening after the first two sessions (ER in 61.3% and 22.9%, respectively; P < 0.05) and caused fewer side effects compared with the contact method. Both cryosurgical methods resulted in a significant decrease in VEGF and tenascin C expression in keloids. CONCLUSIONS: Intralesional cryosurgery is superior to contact cryosurgery in terms of efficacy and safety. Both techniques may have beneficial effects on keloids, at least partially, through the modulation of VEGF and tenascin C expression.

Hyperuricemia: a possible cause of hemospermia.

OBJECTIVE: To report our experience with hemospermia and its relation to hyperuricemia. PATIENTS AND METHODS: Between July 2005 and July 2012, 143 patients with hemospermia presented to the outpatient clinic in our hospital. History, examination, workup, treatment outcomes, and long-term follow-up were reported in a prospective database. Patients were followed up monthly by semen examination till disappearance of hemospermia, then every 3 months for 1 year. We identified 43 patients, who had 4-12 hemospermia attacks for 2-10 months before presentation with no identifiable cause for hemospermia. Of them, 22 had hyperuricemia. The association between hemospermia and hyperuricemia was examined by comparing such 22 hyperuricemic hemospermic patients with the other 21 idiopathic hemospermic patients. RESULTS: The commonest 5 findings identified as possible causes of hemospermia were bilharziasis (21.6%), hyperuricemia (15.4%), idiopathic (14.7%), tuberculosis (8.4%), and chronic prostatitis (8.4%). Hyperuricemic hemospermic patients were significantly of younger age (median of 31.5 vs 45 years), complaining of more painful ejaculation (68.2% vs 9.5%), and had higher serum uric acid (median, 9.3 vs 4.5 mg/dL) compared with those of idiopathic hemospermia. Hemospermia disappeared completely in all patients of the hyperuricemia group vs only 25% of the idiopathic group (P <.001) within a mean of 2 months (range, 1-4 months). CONCLUSION: Hyperuricemia is a new probable cause of hemospermia. Further randomized studies are mandatory for establishment of our postulation.
