Increased femoral cartilage thickness in acne patients using isotretinoin: could it be a sign of early osteoarthritis?

Vitamin A derivatives have inhibitory effects on cartilage tissue, such as decreasing chondrocyte proliferation and collagen synthesis, and increasing the loss of glycosaminoglycans and proteoglycans. Therefore, isotretinoin (a vitamin A derivative) may play a role in the pathogenesis of cartilage-related diseases like osteoarthritis by affecting the balance of cartilage tissue. The aim of this study was to evaluate the distal femoral cartilage thickness in acne patients under the systemic isotretinoin therapy and to determine whether it constitutes a risk factor for the development of osteoarthritis.

Unveiling the impact of psoriasis on liver health: does methotrexate play a villainous role?

Psoriasis might bring about an increased risk of liver diseases like nonalcoholic fatty liver disease and fibrosis. The impact of methotrexate on liver function is still a cause for concern, because of the studies suggesting an increased risk of liver damage and others finding no association. The focus of this study was the liver functions in psoriatic patients investigating the impact of long-term use of methotrexate on liver in psoriasis.

Dermatologic Reactions Following COVID-19 Vaccination: A Case Series.

We describe 7 patients with various dermatologic reactions following COVID-19 vaccination, including herpes zoster (HZ) infection, herpes zoster ophthalmicus (HZO), herpes labialis, and urticaria. Although the reactions described here may be related to COVID-19 vaccination, continued vaccination is recommended, as it is the most effective way to protect against serious COVID-19 infection.

Could Blood Cell-Based Inflammatory Markers Be Used to Monitor Response to Biologic Therapy in Psoriasis?

Objectives: Despite extensive research, there is currently no specific biomarker that reliably and universally indicates treatment response in psoriasis. Multiple studies have evaluated systemic inflammation markers, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), systemic immune-inflammation index (SII), and systemic immune response index (SIRI) in psoriasis patients. However, there are limited studies investigating changes in these markers with biologic therapy.

Relationship between psoriasis and urolithiasis.

The aim of the present study was to investigate whether patients with psoriasis are prone to urolithiasis. Prospective analysis of 67 patients diagnosed as psoriasis (PS group) and 65 volunteers who had never been diagnosed as psoriasis (NPS group) was performed. The levels of oxalate, citrate, calcium, uric acid, magnesium, creatinine, and sodium were evaluated by analyzing the 24-h urine samples.

Evaluation of atherosclerotic risk in rosacea patients through serum fetuin-A and carotid intima media thickness.

Background: The link between rosacea and various systemic conditions has been growing in prominence, even though the relationship between rosacea and cardiovascular disease remains a subject of debate in current research.

Aims: Detecting the connection between rosacea and subclinical atherosclerosis using laboratory and ultrasonographic parameters.

Methods: Fifty rosacea patients and 49 control were included in the study.

"Zooming" in the association between rosacea and fibromyalgia syndrome: ıs it worth mentioning?

Objective: We aimed to detect the frequency of fibromyalgia syndrome in patients with rosacea and determine whether this frequency was affected by the severity of rosacea and the quality of life.

Methods: In this prospective, controlled, cross-sectional study, a total of 94 consecutive rosacea cases and 87 age- and sex-matched controls were enrolled. The severity of rosacea was assessed in light of the findings of the National Rosacea Society Ethics Committee.

Incidence and Prognosis of COVID-19 in Patients with Psoriasis: A Multicenter Prospective Study from the Eastern Black Sea Region of Turkey.

COVID-19 infection can have a poor prognosis, especially in patients with chronic diseases and those receiving immunosuppressive or immunomodulating therapies. This study aimed to investigate the severity of COVID-19 infection in patients with psoriasis and compare the infection severity for systemic treatments and comorbidities. We conducted a study in the dermatology clinics of five different centers in the Eastern Black Sea region of Turkey.

The effect of COVID-19 on development of hair and nail disorders: a Turkish multicenter, controlled study.

Background: A broad spectrum of skin diseases, including hair and nails, can be directly or indirectly triggered by COVID-19. It is aimed to examine the type and frequency of hair and nail disorders after COVID-19 infection.

Methods: This is a multicenter study conducted on consecutive 2171 post-COVID-19 patients.
