The number of hair follicles in Trps1 Knockout (KO) newborn mouse skin was significantly lower than that in wild-type (WT) newborn skin. To gain insight into the functional role of Trps1 in hair development, we transplanted Trps1 KO newborn mouse skin on the backs of nude mice and examined hair growth at day 42 after transplantation. Surprisingly, transplanted skin from Trps1 KO newborn mice gave rise to a substantial amount of hair, although the hair was softer than that of WT mice. Histological examination revealed that the diameter of both hair follicles and hair shafts were significantly lower, whereas the density of hair follicles showed no significant difference between the Trps1 KO and WT mice. We introduce mouse hair follicles as a fascinating model to study the functions of Trps1 in mouse hair growth and pathology. This model suggests that the function of Trps1 is unnecessary for the development of normal hair follicles and hair shafts, although the loss of Trps1 affects the diameters of hair follicles and hair shaft.</p> Yingzhe Zhang, Tomoyuki Nakamura, Fukumi Furukawa, Yasuteru Muragaki ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc/4.0 https://www.pagepress.org/journals/index.php/dr/article/view/7853 Wed, 23 Jan 2019 00:00:00 +0100 Clinical picture, diagnosis and treatment of rosacea, complicated by Demodex mites https://www.pagepress.org/journals/index.php/dr/article/view/7675 <p>The article analyzes the clinical picture and course of rosacea in patients with <em>Demodex</em> mites. It presents the advantages of using the method of confocal laser scanning microscopy over the method of light microscopy of facial skin scrapes. The aimes were to study the influence of <em>Demodex</em> mites on the clinical picture and course of rosacea; to compare laboratory and instrumental diagnostic methods for detecting <em>Demodex</em> mites; to evaluate the effectiveness of external therapy aimed at eliminating <em>Demodex</em> mites. 212 people were examined. The study included healthy patients, patients with a diagnosis of rosacea with the presence and absence of Demodex. The presence of <em>Demodex</em> mites was confirmed by two methods of study (light microscopy of skin scrapes and confocal laser scanning <em>in vivo</em> microscopy). <em>Demodex</em> mites promote the development of acute-inflammatory morphological elements, increase the duration of the condition (more than 5 years, P&lt;0.01) and the probability of recurrence (from 1 to 3 relapses in 39.5% of patients, P&lt;0.05), resulting in a decrease in the quality of life of patients (dermatology life quality index is 12.5±4.5, P&lt;0.05). Antiparasitic drug ivermectin, in the form of an external form, at a concentration of 1% has a high therapeutic efficacy (in 93.3% of cases). <em>Demodex</em> folliculorum shows signs of parasitism, while <em>Demodex</em> folliculorum brevis is a saprophyte. The severity of the condition does not depend on the quantitative load of the mites in the scrape. As an antiparasitic drug, it is recommended to use 1% ivertmectin.</p> Alexey Kubanov, Yuliya Gallyamova, Anzhela Kravchenko ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc/4.0 https://www.pagepress.org/journals/index.php/dr/article/view/7675 Thu, 28 Mar 2019 13:57:41 +0100 Dermoscopy is a new diagnostic tool in diagnosis of common hypopigmented macular disease: A descriptive study https://www.pagepress.org/journals/index.php/dr/article/view/7916 <p>One of the most frequent complaints in dermatology clinics is the eruption of hypopigmented patchy skin lesions. The aim of the study was to investigate the utility of dermoscopy in common hypopigmented macular diseases. Patients with the followings diseases were examined by dermoscopy: vitiligo, pityriasis alba, nevus depigmentosus, achromic pityriasis versicolor, idiopathic guttate hypomelanosis, and extragenital guttate lichen sclerosus. This study showed that these hypopigmented macular diseases might display specific dermoscopic features. In vitiligo, the mean dermoscopic features were the presence of a diffuse white glow with perifollicular pigment, perilesional hyperpigmentation, leukotrichia and the pigmentary network. In idiopathic guttate hypomelanosis, the characteristic features were the presence of multiple, shiny, scaly macules with welland ill-defined edges borders that coalesced into polycyclic macules. For nevus depigmentosus, the mean features were hypopigmented patches with irregular border with a faint reticular network. For pityriasis alba, the fairly ill-demarcated hypopigmented macules with fine scales were the mean feature. In lichen sclerosus, there were white structureless areas, perilesional erythematous halo, follicular plugging and white chrysalis like structures. Dermoscopy of achromic pityriasis versicolor showed a fairly demarcated white area with fine scales localized in the skin creases.</p> Khitam Al-Refu ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc/4.0 https://www.pagepress.org/journals/index.php/dr/article/view/7916 Fri, 21 Dec 2018 00:00:00 +0100 Evaluation of the glycemic effect of methotrexate in psoriatic arthritis patients with metabolic syndrome: A pilot study https://www.pagepress.org/journals/index.php/dr/article/view/7965 <p>Methotrexate (MTX) is a systemic immunosuppressant drug used for the treatment of psoriasis and psoriatic arthritis. Previous studies demonstrated a potential association between psoriasis and diabetes mellitus, obesity, atherosclerosis, hypertension, eventuating into metabolic syndrome. This study aimed at exploring the glycemic effects of MTX in psoriatic arthritis (PsA) patients. In this prospective cross-sectional study, 27 patients with PsA were evaluated. The status of PsA and presence of accompanying metabolic syndrome was determined by standard criteria and indices. Blood indicators including HbA1c, erythrocyte sedimentation rate, fasting blood sugar, total cholesterol, high-density lipoprotein, triglycerides, and C-reactive protein were examined before and 12 weeks after MTX therapy. There were no significant changes between HbA1c levels before and after MTX therapy in both genders (men: P=0.131, women: P=0.803). In addition, HbA1c levels in PsA patients with metabolic syndrome were not different before and after treatment (P=0.250). Finally, HbA1c levels did not change in PsA patients without metabolic syndrome before and after therapy (P=0.506). MTX in PsA patients does not appear to have hyperglycaemic effects in the short-term and can be safely used in patients with metabolic syndrome and diabetes.</p> Tannaz Dehpouri, Ghasem Rahmatpour Rokni, Nematollah Ahangar Narenjbon, Mohamad Goldust, Paul S.

It is also suggested that TSLP has a role in autoimmune diseases such as psoriasis; however, the associated pathways remain unknown. There is currently little information on TSLP in psoriasis vulgaris. We investigated TSLP expressions on lesional and non-lesional skin of psoriasis vulgaris patients using reverse transcription- polymerase chain reaction. TSLP level was also investigated in serum from psoriasis vulgaris patients compared to healthy control using enzyme-linked immunosorbent assay. TSLP expression was higher in lesional skin (1.90) compared to non-lesional skin (1.76); however, the difference was not statistically significant (P&gt;0.05). TSLP serum levels were significantly higher in psoriasis patients (287.40 pg/dL) as compared to controls (114.70 pg/dL) (P&lt;0.05). This study concluded that TSLP levels in the serum of psoriasis vulgaris patients are higher than controls. TSLP was also found in keratinocyte of psoriasis patients, the expression was higher in the lesional compared to non-lesional skin; however, this difference is statistically insignificant. These findings suggest that TSLP may play a role in the pathogenesis of psoriasis vulgaris, but its exact role remains unclear.</p> Oki Suwarsa, Hartati Purbo Dharmadji, Endang Sutedja, Lengga Herlina, Putri Reno Sori, Reti Hindritiani, Reiva Farah Dwiyana, Hendra Gunawan ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc/4.0 https://www.pagepress.org/journals/index.php/dr/article/view/8006 Thu, 20 Jun 2019 09:08:16 +0200 Seborrheic keratosis evolution into squamous cell carcinoma: A truly modified sun-related tumor? A case report and review of the literature https://www.pagepress.org/journals/index.php/dr/article/view/7999 <p>The incidence of seborrheic keratosis (SK) generally increases with age and are mostly localized on the trunk, face and neck, especially on sun-exposed areas. The association between SK and skin malignancies appears to be accidental, but <em>in situ</em> transformation occurs more frequently in sun-exposed areas. Histopathological examination of all SK cases should be considered, especially when SK lesions exhibit atypical clinical manifestations, such as ulceration and cresting, as they may herald malignant transformation. In addition, other features associated with malignant transformation include excoriations or hemorrhages identified on the lesion, modification and evolution of the macroscopic characteristics, and the presence of local erythema or pruritus. Immunocompromised patients exhibit an increased risk of malignant transformation, even when radiation is involved.</p> Ioana Cimpean, Ivan Theate, Olivier Vanhooteghem ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc/4.0 https://www.pagepress.org/journals/index.php/dr/article/view/7999 Wed, 17 Apr 2019 11:59:59 +0200
