Background Rosacea may contribute to the development of cardiovascular (CV) diseases by causing endothelial dysfunction (ED), which is known to be the initial step of atherosclerosis, due to its inflammatory features. Objective This study aimed to assess ED in rosacea patients using the flow‐mediated dilatation (=dilation) (FMD) method. Methods Seventy‐three rosacea patients and 73 age, gender‐matched healthy volunteers were enrolled. Individuals with cardiac risk factors, pregnant, and lactating women were excluded. Demographic, clinical data and anthropometric measurements were recorded. FMD measurement was performed ultrasonographically by a cardiologist. Systolic and diastolic blood pressures (BP) were measured and hemogram, erythrocyte sedimentation rate (ESR), C‐Reactive Protein (CRP), total cholesterol, triglyceride, low‐density lipoprotein (LDL), high‐density lipoprotein (HDL), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), mean platelet volume (MPV), and fasting blood glucose values were assessed. Results The FMD value was statistically lower in rosacea patients compared with healthy controls (p = 0.000). Metabolic syndrome, systolic and diastolic BPs, and plasma NLR were higher in the rosacea group (p = 0.009, p = 0.000, p = 0.000, p = 0.000, respectively). According to the multivariate linear regression analysis, rosacea type significantly predicted FMD. Conclusions Rosacea is not only a disease limited to the skin, but it may also have systemic involvement. A significant difference was found between FMD values measured in between the case and control groups, suggesting rosacea may have an atherogenic effect. Possible cardiac risks should be considered in rosacea patients, and further evaluation could be warranted.
The study aimed to evaluate the efficiency of pomegranate ( Punica granatum) seed oil in wound healing in excised rats. Sixteen female young Wistar Albino Rats weighing approximately 300 to 320 g were randomly divided into 2 groups as the treatment (=pomegranate seed oil group) and control groups in this experiment. Six different wounds 1 cm apart from the midline and each other were formed with a 6 mm punch biopsy instrument. Three wounds were left open (open wound group) whereas 3 wounds were sutured with 4/0 vicryl (closed wound group). Punica granatum seed oil treatment was administered topically to the treatment group, both to open and closed wounds, once a day for 14 days. Parameters for healing were evaluated. Histopathologic examination was performed for the investigation of inflammation, neovascularization, granulation, and fibroblast generation in addition to serologic (enzyme-linked immunosorbent assay) evaluation of rat malondialchehyche, rat glutathione peroxidase, and rat superoxide dismutase. PeriScan PIM 3 System Laser Doppler Blood Perfusion Imager was used for the calculation of blood perfusion. There was a statistically significant difference between inflammation and neovascularization levels and group type on the 14th day in open wounds( P < .05). On the 21st day, the granulation tissue level in the closed wound group was found to be higher in the pomegranate group ( P = 0.000).The results showed that PSE oil is partially effective, although it is not effective in every parameter examined, in the treatment of excised wounds in rats and may be suitable for clinical treatment in humans but large controlled studies are needed.
Background: Psoriasis is a common, chronic, inflammatory skin disease that involves changes taking place as a result of activation of the immune system. Suppressor of cytokine signaling proteins (SOCS) are intracellular proteins that act as endogenous inhibitors of proinflammatory pathways triggered by various cytokines. In this study, the relationship between psoriasis disease and SOCS gene polymorphisms is investigated in relation to the pathogenesis of psoriasis to clarify the psoriasis susceptibility profile. Methods:The SOCS3 rs4969169 and SOCS7 rs3748726 polymorphisms were detected using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The study was approved by the Clinical Research Ethics Committee of Bulent Ecevit University and performed in accordance with the ethical standards established in the 1964 Declaration of Helsinki and later amendments. All participants were informed of the parameters of the study, and they signed consent forms before being included.Statistical analysis was performed using the SPSS 18.0 (SPSS Inc.) package program. Results: For the SOCS3 rs4969169 genotype frequency, the CC/CT genotypes represented 67%/33% in the patient group and 73%/27% in the control group. For the SOCS7 rs3748726 genotype frequency, the TT/TC/CC genotypes made up 89%/9%/1% in the patient group and 91%/8%/1% in the control group. Conclusion:The polymorphisms of SOCS3 rs4969169 and SOCS7 rs3748726 were found to have no effective role in the pathogenesis of psoriasis. This is the first study to investigate this topic, and further studies with larger, more ethnically diverse samples are encouraged.
Background/Objective. Platelet-rich plasma (PRP) has a widespread use in various indications including dermatological conditions. Injectable platelet-rich fibrin on the other hand is prepared without anticoagulants and seems to have a sustained action. This study aimed to compare PRP and PRF injection treatments for facial skin rejuvenation in terms of efficacy, patient satisfaction, and side effects. Patients and Methods. Patients who received facial intradermal injections of PRP or PRF for skin rejuvenation were included in this study. Patients received three injections one month apart and evaluated at follow-up visits for cosmetic results using a high-resolution UVA-light video camera and a surface evaluation software at three regions (frontal, nasolabial, and canthal) as well as for patient satisfaction and side effects. Results. A significant marginal superiority of PRF over PRP was only evident for some canthal cosmetic parameters (canthal smoothness and wrinkles); however, the two groups did not differ in terms of other cosmetic regional parameters. For canthal smoothness, the difference was significant at three months. The two groups did not differ in terms of side effects, pain, and patient satisfaction. Conclusion. This study obtained slightly better outcomes with PRF injections when compared to PRP for facial rejuvenation only at canthal region and only at three months, which disappeared later during the treatment. PRF may represent a viable alternative to PRP for that indication owing to its easier preparation, absence of anticoagulants, and possibly its sustained effect. Further large studies are warranted.
Background Lipophilic basidiomycetous yeasts of the Malassezia genus can cause various skin diseases, such as seborrheic dermatitis, pityriasis versicolor, folliculitis and atopic dermatitis, and even life‐threatening fungemia in newborns and immunocompromised individuals. Routine mycological media used in clinical practice do not contain sufficient lipid ingredients required for the growth of Malassezia species. A recently developed medium, FastFung agar, is promising for culturing fastidious fungal species. Methods In this study, we compared FastFung agar and mDixon agar for culturing Malassezia species from nasolabial fold and retroauricular specimens of 83 healthy individuals and 187 and 57 patients with acne vulgaris and seborrheic dermatitis, respectively. Results Malassezia species were identified using conventional tests and matrix‐assisted laser desorption/ionisation mass spectrometry. In total, 96 of 654 samples (14.6%) contained Malassezia species. The total isolation rate was significantly higher in patients with seborrheic dermatitis (40.4%) than in healthy volunteers (21.7%; p < .05), and the rate of M. furfur isolation was significantly higher for patients with acne vulgaris (13.9%) and seborrheic dermatitis (24.6%) than for healthy individuals (1.5%; p < .05). FastFung agar was superior to mDixon agar in M. furfur isolation (p = .004) but showed similar performance in the case of non‐M. furfur species (p > .05). Among cultured Malassezia species, perfect agreement between mDixon agar and FastFung agar was found only for M. globosa (κ = 0.90). Conclusion Our results indicate that FastFung agar favours the growth of Malassezia species and should be useful in clinical mycology laboratories.
