Assessment of the Quality of Life, Prevalence of Depression, and the Level of Interleukin 6 in Patients with Pemphigus Vulgaris.

Pemphigus vulgaris (PV) is a life-threatening, autoimmune blistering disease affecting the skin and mucous membranes, exerting a detrimental effect on the quality of life (QOL). Our aim was to evaluate the psychological status and QOL of patients with PV and investigate Interleukin-6 (IL-6) as a possible contributor to the pathogenesis of pemphigus and associated depression. The study included 22 patients with PV, 21 patients with depression, and 20 normal controls. All the 63 participants were subjected to assessment of their QOL, psychiatric profile, as well as estimation of serum level of IL-6. All (100%) of the included patients with PV had a negative effect on their QOL, which was significant compared with controls (P<0.001). Among patients with PV, 13 patients (59.1%) had depression. IL-6 was non-significantly elevated in the pemphigus group when compared with the controls (P=0.057). QOL was significantly worse in the depressed pemphigus subgroup compared with the non-depressed pemphigus subgroup (P=0.006 and <0.001) respectively. However, IL-6 was non-significantly elevated in the depressed pemphigus subgroup compared with the non-depressed pemphigus subgroup (P=0.095). A marked deterioration in the QOL was observed in patients with pemphigus. More than 50%, but not all, of patients with pemphigus had depression. IL-6 was non-significantly elevated in patients with pemphigus.

Comparing the Efficacy of Mesotherapy to Topical Minoxidil in the Treatment of Female Pattern Hair Loss Using Ultrasound Biomicroscopy: A Randomized Controlled Trial.

The efficacy of mesotherapy in the treatment of female pattern hair loss (FPHL) has not yet been evaluated. Aim of the study was to compare the initial efficacy and safety of mesotherapy containing nutritional supplements to topical minoxidil 5% solution in FPHL. 30 patients with FPHL were randomly classified into two equal groups: Group A applied minoxidil 5% lotion twice daily; Group B was injected with mesotherapy once weekly. For both groups ultrasound biomicroscopy (UBM) was performed before and at the end of the 12th week of treatment. After treatment, no significant difference was found between both groups with regard to either improvement of hair density and hair loss (P=0.27 and 0.056, respectively), nor the degree of improvement of Ludwig's classification as assessed by the investigator (P=0.210). A significant difference was observed between both groups (P=0.001) with the highest degree of satisfaction in the mesotherapy group. In group A, no significant difference was found in the number of hair follicles or the diameter of the largest hair follicle (P=0.244 and 0.925, respectively). In group B, a significant difference was found in the number of hair follicles (P=0.001), with no significant difference in the diameter of the largest hair follicle (P=0.105). The mesotherapy group showed more improvement with regard to the increase in the number of the hair follicles after treatment (P=0.007). Limitation of the study is small sample size, and relatively short duration of treatment. Mesotherapy, containing nutritional supplements only, is an effective, more acceptable to patients, and more tolerable modality compared with topical minoxidil in the treatment of FPHL.

Toenail concentrations of zinc, selenium and nickel in patients with chronic recurrent warts: A pilot two-group comparative study.

BACKGROUND: Normal immune functioning requires sufficient levels of trace elements including zinc and selenium, while elements such as nickel can be immunotoxic. AIM: To assess long-term abnormalities in zinc, selenium and nickel levels in patients with chronic recurrent warts. METHODS: Toenail samples were taken from 28 patients with chronic recurrent warts and 30 apparently healthy matching controls were analysed. Toenail concentrations of zinc, selenium and nickel were measured using inductively-coupled plasma-optical emission spectroscopy. RESULTS: Selenium levels were significantly higher in patients than in controls (P = 0.03). Levels of trace elements did not correlate with the number or duration of warts. Toenail nickel levels in all subjects were higher than globally reported values. LIMITATIONS: A small sample size and the absence of regional reference ranges for concentrations of trace elements in toenails. CONCLUSION: Zinc does not seem to be involved in the chronicity of warts, and it is unclear if selenium has a protective role against warts. Our finding of high concentrations of nickel in both patients and controls raises concerns about environmental exposure.

Higher Expression of Toll-like Receptors 3, 7, 8, and 9 in Pityriasis Rosea.

BACKGROUND: Pityriasis rosea (PR) is a common papulosquamous skin disease in which an infective agent may be implicated. Toll-like receptors (TLRs) play an important role in immune responses and in the pathophysiology of inflammatory skin diseases. Our aim was to determine the possible roles of TLRs 3, 7, 8, and 9 in the pathogenesis of PR. METHODS: Twenty-four PR patients and 24 healthy individuals (as controls) were included in this case control study. All recruits were subjected to routine laboratory investigations. Biopsies were obtained from one active PR lesion and from healthy skin of controls for the detection of TLR 3, 7, 8, and 9 gene expression using real-time polymerase chain reaction. RESULTS: This study included 24 patients (8 females and 16 males) with active PR lesions, with a mean age of 28.62 years. Twenty four healthy age- and sex-matched individuals were included as controls (8 females and 16 males, with a mean age of 30.83 years). The results of the routine laboratory tests revealed no significant differences between both groups. Significantly elevated expression of all studied TLRs were detected in PR patients relative to healthy controls (p < .001). CONCLUSIONS: TLRs 3, 7, 8, and 9 might be involved in the pathogenesis of PR.

Is There a Link between Human Herpesvirus Infection and Toll-like Receptors in the Pathogenesis of Pityriasis Rosea? A Case-control Study.

Human herpesvirus (HHV) 6 and 7 are involved in the pathogenesis of pityriasis rosea (PR). Our aim was to evaluate the role of the innate immune response in PR through the detection of Toll-like receptors (TLR) 2, 3, 4, 7, 8, and 9 expression in the skin of affected patients and to detect the possibility of being induced by HHV-6 and/or HHV-7 viral coexistence in these patients. Twenty-four patients with PR and 24 healthy controls were included in this case-control study. Biopsy was obtained from the PR lesion and from the healthy skin of controls for detection of HHV-6 and 7 as well as TLRs 2, 3, 4, 7, 8, and 9 gene expression using real-time polymerase chain reaction (PCR). Significantly elevated expression of all studied TLRs and significantly higher viral load of HHV-6 and 7 in PR cases were detected. A significant higher expression of TLR2 and 4 in HHV-7 positive cases and a significant positive correlation between TLR9 and HHV-7 viral load were documented. HHV6 and 7 may also be involved in the pathogenesis of PR via TLR pathways.

Efficacy and safety of fractional carbon dioxide laser for treatment of unwanted facial freckles in phototypes II-IV: a pilot study.

Facial freckles are a cosmetic concern to Egyptians, particularly young females. Several therapeutic lines exist with variable response rates and limitations. Fractional carbon dioxide (FCO2) laser provides minimal ablation and therefore less down time and less side effects. The efficacy and safety of this laser technology have still not been studied in freckles. The aim of this study is to assess the efficacy and safety of FCO2 laser in the treatment of unwanted facial freckles in Egyptians. Twenty patients undergone a single session of FCO2 laser and then were followed up clinically a month later. Photographs were taken before treatment and at follow-up visit and were assessed by three blinded investigators. Percent of global improvement was measured on a 4-point grading scale. Patient's satisfaction and adverse events were recorded. Two patients (10 %) showed grade 1 improvement, while eight patients (40 %) showed grade 2 improvement. Nine patients (45 %) showed grade 3 improvement, and only one patient (5 %) showed grade 4 improvement. FCO2 laser resurfacing is effective and safe in treatment of facial freckles in skin phototypes II-IV. It can offer a more practical alternative to topical treatments, and a cheaper alternative to Q-switched lasers.

Clinical study of nail changes in vitiligo.

Both vitiligo and alopecia areata (AA) are associated together, associated with other autoimmune diseases, and autoimmunity is one of the important theories in their etiology. Nail changes are a known association with AA, thus we hypothesized that nail changes can be found in vitiligo patients. On revising the literature, only two types of nail changes were described in association with vitiligo. Our aim was to study the frequency and types of nail changes among vitiligo patients in comparison with normal healthy volunteers. This multi-centric study was carried on 91 patients with vitiligo, as well as 91 normal healthy control subjects who were age- and sex-matched. Nails were examined for changes in nail plates as regards striations, texture, curvature, dystrophy, and pigmentation. The presence or absence of the thumb lunula was also reported. Nail changes were observed in 62 patients (68.1%) and 46 (50.5%) control subjects with a statistically significant difference (P = 0.016). Longitudinal ridging and absent lunula were significantly higher in patients than in the controls (P = 0.001 and 0.037, respectively). Other reported nail abnormalities in the current study included punctate leukonychia, pitting, flag sign, and Terry's nails. Awareness of this association will widen the clinician's perspective to carefully examine the nail changes in vitiligo patients and conversely examine patients with nail changes for vitiligo.
