IntroductionInherited ichthyoses are caused by mutations in various genes important for keratinocyte differentiation and epidermal barrier function. Although ichthyoses are rare disorders, they require costly long-term medical management, and thus there is a need for efficient preventive and therapeutic strategies.AimWe performed a retrospective study to determine the frequency, types, clinical presentation and associated genomic errors of primary hereditary ichthyoses in Egyptian patients and their relatives consulting the Genetics Clinic, Pediatric Hospital, Ain Shams University.Material and methodsThe outpatient log books of patients between January 2000 and December 2014 were reviewed, and diagnosis of new patients was confirmed through examination by a dermatologist. All epidemiologic, demographic, and clinical data were extracted and recorded in especially designed data collection forms.ResultsThe occurrence rate of primary hereditary ichthyoses in our study was 25.7% of genodermatosis patients attending the genetics clinics and 1 per 2359 patients attending the Pediatric Hospital. The commonest type of ichthyosis in our study was Lamellar ichthyosis (38%), followed by congenital ichthyosiform erythroderma (26.8%). Consanguineous marriage was reported among the parents of 79% of patients and positive family history was reported in 72% of patients.ConclusionsTo the best of our knowledge, this preliminary study is the first report on the clinico-epidemiological features of primary hereditary ichthyoses in Egypt. The high rate of prenatal consanguinity among parents of our patients may account for the high frequency of these genodermatoses in Egypt. This highlights the importance of genetic counselling and prenatal diagnosis in Egypt.
Background Acne scarring is often the primary concern of a patient with acne. Acne scarring can cause depression and is a risk factor for suicide. Patients feel their appearance interferes with their relationships and chances of future employment. Acne scars can be classified into 3 different types: atrophic, hypertrophic, or keloidal. Atrophic acne scars are the most common type. Atrophic acne scars are divided into three main types: ice pick, rolling and boxcar scars. Aim of the Work To compare the results of whole facial area versus Focal Acne Scar Treatment (FAST) by factional CO2 laser in a split face study. Patients and Methods The present study is a split face comparative study which included 20 adult patients with atrophic acne scars ranged from 18 to 44 years old of both sex. The study was approved by the Research Ethical Committee, Faculty of Medicine, Ain Shams University and fulfilled all the ethical aspects required in human research. All patients received full information about description of the procedure of treatment, possible side effects, photo documentation and they all provided written consent. Results Patients were asked to compare the pain, peeling and complications between the right and left sides post CO2 fractional treatment: pain was more at right side in 35% of cases and more at left side in 30% of cases and equal in the rest of cases, peeling was faster at the right side in 60% of cases, faster at the left side in 20% of cases and equal at the rest of cases, 4 of the patients had post inflammatory hyperpigmentation (1 patient at right side, 2 patients at left side and 1 patient at both sides), no other complications were recorded as secondary infection, scaring keloid and prolonged erythema. Conclusion We compared the results of whole facial area treatment in the right side of the face versus Focal Acne Scar Treatment (FAST) in the left side by factional CO2 laser. We discovered that there is a statistically highly significant relationship between the improvement of acne scars and treatment with fractional CO2 laser by the either techniques. Both techniques are preferable in treating acne scars in equal degree.
Background Vitiligo is acquired depigmentary disorder characterized by destruction of the epidermal melanocytes leading to the loss of the skin color. Oxidative stress has a major role in the aetiopathogenesis and in melanocytic destruction due to its accumulation in the melanocytes and the hazardous effects to all compartments of the cell. Objective The aim of the work was to evaluate the level of E-cadherin and H2O2 level in vitiligo versus controls. Subjects This is a case control study which was carried out at Department of Dermatology, Venereology and Andrology,New Cairo Police Academy Hospital on 20 Subjects were divided into two groups, Group I included 10 patients having non segemental vitiligo. Group II included 10 non vitilignous controls were included in the study. Results We found that H2O2 level is increased in NSV patients when compared with healthy individuals. While E-cadherin level is significantly decreased in vitiligo skin compared to normal skin. Conclusion As compared to controls, increased H2O2 levels levels were suggestive of oxidative stress in patients of vitiligo in our study. From our results we can conclude that vitiligo is not a disease confined to melanocytes only, keratinocytes also showed certain pathological changes in vitiliginous lesions. As functional and structural units with melanocytes, keratinocytes in depigmented epidermis may constitute a different microenvironment compared to those in normally pigmented epidermis. These differences include obvious loss of cell to cell adhesion between keratinocytes and melanocytes and between keratinocytes and each other, which in turn may affect the pigmentary system of the skin.
