The results show that the balance between oxidant and anti-oxidants was disrupted and the oxidative stress increased in melasma. These results improve the understanding of etiology-pathogenesis of the disease and its treatment.

The oral isotretinoin treatment has been demonstrated as having increased the platelet density, hemoglobin levels and having decreased red-blood-cell distribution width level significantly.

Methods: Overall, 85 separate exemplification groups were formed to reflect the population density, and the demographic data of the region they represent. In the first stage, the individuals, who were selected in random order, were invited to a Family Physician Unit at a certain date and time. The dermatological examinations of the volunteering individuals were performed by only 3 dermatology specialists. In the second stage, those individuals who had symptoms of BD were invited to our hospital, and the Pathergy Test and eye examinations were performed. Results:The annual prevalence of RAS was determined as 10.84%. The annual prevalence was determined to be higher in women than in men (p=0.000). It was observed that the prevalence was at the peak level in the 3 rd decade, and then decreased proportionally in the following decades (p=0.000). It was also observed that the aphtha recurrence decreased in the following decades (p=0.048). The Behçet's prevalence was found to be 0.60%. The prevalence in women was found to be higher than in men (0.86% female, 0.14% male; p=0.022). Conclusion: While the RAS prevalence ratio was at an average value when compared with the other societies; the BD prevalence was found as the highest ratio in the world according to the literature.

Recent studies have suggested the involvement of increased reactive oxygen species levels and decreased antioxidant system functions in psoriasis pathogenesis. In this study, we aimed to examine to investigate possible associations between the manganese superoxide dismutase (MnSOD Ala-9Val) and glutathione peroxidase (GPx1 Pro198Leu) polymorphisms and psoriasis susceptibility and disease progression in a Turkish population. The study group consisted of 100 unrelated patients with psoriasis and 167 unrelated healthy controls. Genomic DNA was extracted from peripheral leukocytes of whole blood which were obtained from all patients and control subjects. Genotyping was performed to identify MnSOD Ala-9Val and GPx1 Pro198Leu polymorphisms by a method based on PCR amplification and detection of polymorphisms with hybridization probes labeled with fluorescent dyes. Genotype and allele frequencies were compared between patients with psoriasis and 106 healthy control subjects. There was no significant difference between the MnSOD Ala-9Val single nucleotide polymorphism (SNP) genotype distributions and allele frequencies of the psoriasis patients and the control group (p = 0.99 and p = 0.89, respectively). There was also no significant difference between distributions of the genotype or allele frequencies of the GPx1 Pro198Leu SNP of the patient groups and control subjects (p = 0.99 and p = 0.96, respectively). Also, no significant difference was found between clinical severity of psoriasis and MnSOD Ala-9Val and GPx1 Pro198Leu polymorphism. This is the first report investigating the possible associations between the MnSOD Ala-9Val and GPx1 Pro198Leu polymorphisms and psoriasis susceptibility and disease progression in the Turkish population even if no significant difference was found between patient groups and control subjects. Further studies with large cohort on different populations and ethnicities will be able to better clarify the association.

Amaç: Tüm dünyada yaşlıların genel nüfusa oranı giderek artmaktadır. Sağlık hizmetlerinin planlanmasında bu popülasyona yönelik epidemiyolojik çalışmalar yol gösterici olacaktır. Yöntem: [2005][2006][2007][2008][2009][2010][2011][2012][2013] Objective: All over the world, the proportion of elderly in general population tends to increase. Epidemiological studies concerning this part of the population will be guiding while planning health services. Methods: Data of a total of 2734 geriatric patients admitted between the years 2005-2013 were analyzed. Hospital-based patient registry records were used for data collection. Patients were classified into 26 different groups in terms of types of their cutaneous diseases. The data were analyzed according to age, gender, and season. Results: Among 2734 patients included in the study, 1519 were males (55.6%) and 1215 (44.4%) were females. Mean age was 70.94±5.76 years. When analyzed in decreasing order of incidence, the first five groups were eczema (20.5%), fungal skin diseases (18%), pruritus (12.8%), erythematous-squamous disease (6.7%), and viral skin diseases (5.4%). Conclusions:This study provides important data on the frequency of dermatologic diseases in elderly patients, and also shows variations in the frequency depending on age, gender, and season. We believe that this study will create awareness about the extent and patterns of dermatologic problems in geriatric patients.

It was determined that colchicine lowers the levels of NLR, white blood cell count and RDW. Furthermore, no changes were seen on MPVs, PLRs and Hb levels.
