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.

Combined Jessner Solution and Trichloroacetic Acid Versus Trichloroacetic Acid Alone in the Treatment of Melasma in Dark-Skinned Patients.

BACKGROUND: Melasma is a common challenging pigmentary skin disorder especially in dark-skinned females urging them to seek medical help. Many modalities of treatment are available, but none is satisfactory. OBJECTIVE: To compare safety and efficacy of combined trichloroacetic acid (TCA) (20%-25%) and Jessner's solution versus TCA (20%-25%) alone in dark patients with melasma. MATERIALS AND METHODS: The study design was a split face, right-left, assessor-blinded, randomized controlled study. Twenty-four adult female patients (skin phototypes IV-V) with bilateral melasma were treated for 6 sessions at 2 weeks intervals. Clinical assessment of the 2 sides of the face with Melasma Area and Severity Index (MASI) score was performed, and photographs were taken before and after the peeling course. RESULTS: Both therapeutic modalities showed significant decrease in MASI score, which was significantly lower on the side treated with both Jessner solution and TCA. There were significant negative correlations between the percentage of improvement of MASI score and both age of the patients and duration of the melasma. CONCLUSION: Dark skin melasma can be treated with both regimens safely and effectively; however, combined Jessner solution and TCA is more effective.

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.
