Behçet's disease (BD), first described by Hulusi Behcet, is a multisystemic disease characterized by recurrent oral and genital ulcerations, ocular and cutaneous lesions, arthritis and vascular disease. Pyoderma gangrenosum (PG) is a rare, chronic, sterile pustular and progressive ulcerative process of unknown cause; sometimes can participate in the differential diagnosis of Behcet's ulceration. A 33-year-old woman complained a severe genital ulcer. She had a purulent oozing and stinky ulceration on the right side of labium minor measuring 5-8 cm. A punch biopsy at ulcer margin showed that the lymphocytic panniculitis was extending to the subcutaneous fat tissue without fibrin deposition or necrotic changes in the vessel wall. Based on the clinical and histological findings, she was diagnosed as genital ulcerative PG, which occurred during the exacerbation of BD.

Introduction: Increased oxidative stress (OXS) and a high prevalence of psychiatric disorders are seen in alopecia areata (AA). However, OXS and psychiatric disorders have been studied separately in AA patients. Aim: To determine the effects of anxiety and depression symptoms on OXS in AA patients. Material and methods: The anxiety and depression levels of 33 AA patients and 33 normal controls (NC) were determined using the Hospital Anxiety and Depression Scale. The oxidative stress index (OSI) was calculated by measuring serum total antioxidant status (TAS) and total oxidant status (TOS) levels in AA patients and NC. Results: The AA patients had higher anxiety and depression scores than NC (p < 0.001 for both). Total oxidant status (p = 0.002) and OSI (p < 0.001) values were higher, and TAS (p < 0.001) levels were lower, in patients with AA compared to NC. However, patients' anxiety and depression scores were not correlated with the TAS, TOS, or OSI values (p > 0.05). There was no significant difference in TAS, TOS, or OSI values between patients with high and low anxiety or depression scores (p > 0.05). Conclusions: These results show that OXS, anxiety, and depression scores were higher in patients with AA compared to NC. However, anxiety and depression scores were not associated with OXS in AA patients. More extensive studies should be performed to investigate the relationship between psychological status and OXS in patients with AA.

Background: Sensitive skin (SS) is a syndrome in which neurosensory disorders accompany epidermal barrier dysfunction. However, it is not yet clear how high anxiety levels affect the biophysical parameters of the skin in patients with SS. Objectives:We aimed to investigate the relationship between anxiety levels and facial neurosensitivity, the erythema index, sebum content, and sensitive skin scale scores in individuals with sensitive skin. Methods:The study was carried out on 35 individuals with SS and 40 without SS over three months. In the study, a questionnaire to detect the presence of sensitive skin, the sensitive skin scale for sensitive skin severity, the lactic acid sting test (LAST) to show facial neurosensitivity, a Mexameter for erythema index measurement, and a Sebumeter for sebum content measurement were used. In addition, the anxiety levels of the patient and control groups were measured using the hospital anxiety and depression scale (HADS).Results: While the HADS-Anxiety scores were found to be significantly higher in patients with sensitive skin, there was no significant difference in the HADS-Depression scores. Moreover, a strong positive correlation was found between the HADS-Anxiety scores and the erythema index in patients with sensitive skin. Conclusions:Sensitive skin is a disorder that can sometimes occur without any dermatological examination findings. In particular, the sensations of the patients, along with their anxiety levels, are essential parameters that should be evaluated in the approach to patients with sensitive skin.

Oral isotretinoin is frequently used in the treatment of young acne patients. However, knowledge levels and attitudes about this treatment have not been studied in the parents previously. We aimed to investigate the knowledge levels and concerns about oral isotretinoin in the parents of adolescent acne patients. We conducted a cross‐sectional study on 136 parents of adolescent patients with moderate to very severe acne vulgaris who answered the questionnaire about oral isotretinoin treatment. Demographic data and acne characteristics were recorded. The parents' knowledge levels and concerns about the treatment process were asked by the questionnaire. Since 32 parents have never heard oral isotretinoin before, they were excluded from the study. Of the remaining 104 parents, 80.8% were female and 19.2% were male. Of the parents, 62.5% had some concerns about oral isotretinoin treatment and 34.6% had no idea whether the drug is suitable for the use of <18 years. 52.9% stated that they think the drug will damage the liver. The most known and worrying side effects were dry lips and vision problems, respectively. The knowledge levels about oral isotretinoin treatment and its side effects were low in the parents of adolescent acne patients, leading to prejudice to the drug.
