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.

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.

Introduction: Systemic isotretinoin is the most effective treatment modality in acne vulgaris; however, both patients and physicians hesitate to use it due its side effects. Objectives: The aim of this study is to determine the prevalence of fatigue, myalgia and low back pain during systemic isotretinoin treatment; and to determine their relationship with age, gender, treatment duration, daily isotretinoin dose and isotretinoin-naiveness of the patient. Methods: This is a cross sectional study including the acne vulgaris patients, aged between 13 to 40 years, who have at least received one month of oral isotretinoin treatment. Patients were questioned for side effects during their follow-up visits; a physical therapy and rehabilitation specialist further evaluated patients complaining of low back pain. Results: Fatigue was reported by 4.4% of the patients, myalgia by 2.8% and low back pain by 25% of the patients; 2.2% had inflammatory and 22.8% had mechanical low back pain. None of the patients had sacroiliitis. All the side effects that were examined were found to be independent of age, gender, isotretinoin dosage (mg/kg/day), treatment duration and isotretinoin-naiveness. Conclusions: The side effects are not as common as feared; thus, patients and physicians should not hesitate to use systemic isotretinoin in indicated cases.
