RESUMO

BACKGROUND: Middle Eastern women worldwide increasingly seek aesthetic treatment to enhance their beauty and improve self-esteem, but literature describing standards of beauty across the Middle East are scarce. Knowledge of facial anthropometry and Middle Eastern subregional beauty preferences and aesthetic weaknesses are key to develop an effective facial enhancement strategy that does not jeopardize ethnic identity or facial harmony. METHODS: Dermatologists and plastic surgeons from 8 Middle Eastern countries who had 7.5-25 (mean 13.5) years of experience in aesthetic medicine examined female Middle Eastern beauty in 4 geographic subregions: the Gulf (comprising Bahrain, Kuwait, Saudi Arabia, and the United Arab Emirates), Iran, Lebanon, and Egypt. They developed consensus opinions regarding facial beauty, aesthetic deficiencies, and injectable treatment solutions. RESULTS: Facial anthropometry differs between Middle Eastern and Western women, and also within the region. Although subregional differences are seen, beauty is generally recognized by an oval or round face; temple fullness; pronounced, elevated, arched eyebrows; large almond-shaped eyes; well-defined, laterally full cheeks; a small, straight nose; full lips; a well-defined jawline; and a prominent, pointed chin. The relative prominence of the nose necessitates attention to the lips and the shape and projection of the chin. Aging is often accompanied by midface sagging that leads to increased heaviness in the lower facial third. CONCLUSIONS: Middle Eastern beauty is characterized by striking eyes, defined cheeks, and full lips. These consensus opinions inform aesthetic practitioners who treat Middle Eastern women worldwide about their aesthetic ideals and the implications for treatment.

RESUMO

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.

RESUMO

New treatment modalities for vitiligo acting by changing certain cytokines and metalloproteinases are newly emerging. The aim of this work is to To assess the efficacy of trichloroacetic acid (TCA) chemical peel, dermapen, and fractional CO2 laser in treatment of stable non-segmental vitiligo and to detect their effects on IL-17 and MMP-9 levels. Thirty patients with stable vitiligo were recruited in a randomized controlled study. They were randomly categorized into three equal groups. Group 1: TCA peel, Group 2: dermapen machine, and Group 3: Fractional CO2 laser. Skin biopsies were taken from treated areas and from control areas for which MMP-9 and IL-17 tissue levels were measured using ELISA. The 30 vitiligo patients had low basal tissue MMP-9 levels and high baseline IL-17 tissue levels. As regards the three different used modalities, all of them caused rise in MMP-9 as well as IL-17 levels and almost their levels were much more elevated with repetition of the previously mentioned traumatic procedures. TCA 25% peel proved to be the most effective modality both clinically and laboratory and it can be used prior or with other conventional therapies in the treatment of vitiligo.

RESUMO

To study protection of melanocytes from stress-induced cell death by heme oxygenases during depigmentation and repigmentation in vitiligo, expression of isoforms 1 and 2 was studied in cultured control and patient melanocytes and normal skin explants exposed to UV or bleaching agent 4-TBP. Similarly, expression of heme oxygenases was followed in skin from vitiligo patients before and after PUVA treatment. Single and double immunostainings were used in combination with light and confocal microscopic analysis and Western blotting. Melanocyte expression of heme oxygenase 1 is upregulated, whereas heme oxygenase 2 is reduced in response to UV and 4-TBP. Upregulation of inducible heme oxygenase 1 was also observed in UV-treated explant cultures, in skin of successfully PUVA-treated patients and in melanocytes cultured from vitiligo non-lesional skin. Heme oxygenase encoding genes were subsequently cloned to study consequences of either gene product on cell viability, demonstrating that HO-1 but not HO-2 overexpression offers protection from stress-induced cell death in MTT assays. HO-1 expression by melanocytes may contribute to beneficial effects of UV treatment for vitiligo patients.

RESUMO

OBJECTIVE: To evaluate the efficacy of two topically applied immunomodulative agents through the detection of lymphocyte subsets using monoclonal antibodies against CD4, CD8 and MHC II. METHODS: Fifty patients from the Departments of Medical Biochemistry, Dermatology and Pathology at Cairo University with different degrees of alopecia areata (AA) were included in this study. They were classified into two groups each of 25 patients. Each patient was treated with the immunomodulative agent on one side of the scalp and the other side was left as a control. Biopsies were taken from all patients at the beginning of treatment and at the end of the study. Tissue specimens were prepared for histologic and immunophenotypic analysis. The main outcome measures were the uses of diphencyprone (DPCP) and topical tacrolimus as two topical immunotherapeutic modalities in the treatment of AA. RESULTS: A clinical response of 68% was achieved in group A (treated with DPCP) while group B (treated with 0.1% tacrolimus) showed an insignificant clinical response. Decreased expression of CD4 and increased expression of CD8 and MHC II was detected in the post-treated areas compared with pretreated areas in cases treated with DCPC. In tacrolimus-treated cases, there was a decrease in CD4 and MHC II, with no change in CD8 between the pre- and post-treated areas. CONCLUSION: DCPC is one of the most accepted therapeutic modalities in the treatment of AA, with a favourable prognosis among patchy hair loss. MHC II expression was the one correlating with clinical response. Tacrolimus, though beneficial in other dermatoses, could not be considered effective in the treatment of AA.

RESUMO

PUVA is the first therapeutic choice in early stages of mycosis fungoides (MF). In this study the effect of PUVA on bcl-2 expression in MF was assessed in 15 patients (three stage Ia and 12 stage Ib) and 10 controls. Two biopsies were taken from each patient before and after 24 sessions of PUVA therapy. Histopathological assessment and immunohistochemical staining for bcl-2 was performed and showed positive bcl-2 staining of lymphocytes in 53% of MF cases (8/15) before PUVA, with no statistically significant difference in the bcl-2 level before and after PUVA therapy (P value 0.3). A statistically significant difference was found in the bcl-2 level between control samples and MF patients' biopsies before (P value 0.02) and after PUVA therapy (P value 0.011). In conclusion, a lack of decline in the bcl-2 level and the absence of clinical or histopathological correlation with the bcl-2 level before and after PUVA therapy in MF patients suggest that PUVA-induced apoptosis in MF cases may occur through pathways other than bcl-2 inhibition.

RESUMO

BACKGROUND: Several clinical and laboratory observations point to the possible microscopical affection of normal-looking skin in leprosy. OBJECTIVE: This study was carried out to verify the microscopical affection of apparently normal-looking skin in different types of leprosy. PATIENTS AND METHODS: The study included 50 patients with different clinical types of leprosy. Biopsies from both skin lesions and normal-looking skin were obtained from each patient and examined for microscopical evidence of leprosy. RESULTS: Microscopical affection of normal-looking skin was detected in 52% of our cases, with higher incidence of affection towards the lepromatous end of the disease. CONCLUSION: Our findings underscore that the incidence of microscopical affection of normal-looking skin in leprosy is much higher on the lepromatous end of the spectrum of leprosy than on the tuberculoid end; during treatment, the leprosy granulomas may disappear from the normal skin before the clinical lesions. Moreover, the microscopic picture of indeterminate leprosy can be observed in the normal-looking skin of patients with tuberculoid leprosy or lepromatous leprosy, and this description appears not to be confined to the entity known as indeterminate leprosy.
