Materials And Methods: The sociodemographic characteristics of the patients and disease severity according to the Food and Drug Administration criteria were recorded.

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.

Could there be an association between Hashimoto's thyroiditis and demodex infestation?

Background: Human demodex mites are parasites that live in the pilosebaceous unit and can result in the disease demodicosis. While demodicosis may occur as a primary skin disease; immunosuppression, and topical or systemic immunosuppressive treatments can cause secondary demodicosis. It is known that thyroid hormones may cause skin changes, such as xerosis, and thereby may also modulate immune responses in the skin.

Rates of skincare product and cosmetic procedure use in patients with acne vulgaris and the effective factors: A multicenter study with 1,755 patients.

Background: Skincare products and cosmetic procedures are used as an adjunct or complementary to conventional drug therapy for acne vulgaris (AV).

Objective: To evaluate the use of skincare products and the frequency of cosmetic procedures in AV treatment.

Methods: A total of 1,755 patients with AV completed the survey prepared by the researchers and the Cardiff Acne Disability Index (CADI) questionnaire.

Social media use in patients with acne vulgaris: What do patients expect from social media?

Background: Acne vulgaris (AV) may affect external appearance and significantly deteriorate the quality of life of patients. Therefore, patients make various inquiries about their disease and seek treatment options.

Aims: To investigate the social media usage habits of patients with AV concerning their diseases, and their recommendations for dermatologists related to social media use.

Analysis of 3702 patients with acne vulgaris and concomitant comorbidities in Turkey: a multi-centered, prospective, controlled study.

Background: Acne vulgaris is a chronic inflammatory skin disease that affects the pilosebaceous unit. Although it is considered to be a skin-limited disease, different clinical studies have recently been published in which the disease is accompanied by systemic symptoms. In this study, systemic comorbidities accompanying acne vulgaris and the relationship between existing comorbidities and disease severity are investigated.

Imiquimod 5% Cream Versus Cryotherapy in Classic Kaposi Sarcoma.

Background: Classic Kaposi sarcoma usually remains on the skin and has a slow progression; thus, local treatment methods are preferable. Imiquimod is an immunomodulatory agent with antiviral, antitumoural, and antiangiogenic properties that is expedient against Kaposi sarcoma.

Objectives: We aimed to clarify whether imiquimod is effective on classic Kaposi sarcoma lesions by comparing imiquimod treatment with cryotherapy, which is the most-used treatment method in our department for this disease.

Uptake of an Acrochordon Incidentally Detected on 68Ga Prostate-Specific Membrane Antigen PET/CT.

Ga prostate-specific membrane antigen (PSMA) PET/CT is a promising tool for imaging of prostate cancer. Ga-PSMA PET/CT uptake of prostate cancer and its metastases are reflective of significant overexpression of PSMA. However, PSMA expression of benign neoplasms and nonprostate epithelial malignancies is not very well defined.

Symmetrical drug-related intertriginous and flexural exanthema (SDRIFE) induced by oral metronidazole.

Baboon syndrome is a special form of systemic contact dermatitis to systemic or local administration of contact allergens. Baboon syndrome without known previous cutaneous sensitisation was also described as drug-related baboon syndrome or symmetrical drug-related intertriginous and flexural exanthema (SDRIFE). The major drugs causing SDRIFE was beta-lactam antibiotic such as amoxicillin and ampicillin.

The effects of isotretinoin on the ovarian reserve of females with acne.

There are some side effects of isotretinoin in many organs. However, a study investigating the effects of isotretinoin on the human ovarian reserve has not been reported previously. The study was conducted to investigate possible effects of isotretinoin on ovarian reserve.

Effectiveness of systemic treatment agents on psoriatic nails: a comparative study.

Background: Nails, one of the most visible sites of body, are frequently involved in psoriasis and accepted as the most difficult site for topical treatment because of their anatomical structure. Healing of the psoriatic nails usually occurs when systemic therapy is initiated to treat severe skin psoriasis or joint involvement, but sometimes systemic therapy is essential for severe nail psoriasis, although Psoriasis Area and Severity Index (PASI) score is low or none of the joints are affected. In this case, knowing which systemic agent is most potent on nail findings is important.

Comparison of effects of 5 and 10 mg oral desloratadine and levocetirizine on histamine-induced wheal and flare response in healthy volunteers.

Background: Levocetirizine and desloratadine are mostly used as H1-antihistamines in the treatment of allergic disease in 5 and 10 mg doses.

Objective: In this study, the efficacy of single oral dosages of 5 and 10 mg desloratadine and levocetirizine were compared by using histamine-induced wheal and flare reactions.

Methods: Eighty healthy volunteers were randomized for four double-blinded treatment with desloratadine 5 and 10 mg and levocetirizine 5 and 10 mg.

Effects of isotretinoin on serum vitamin E levels in patients with acne.

Anecdotal reports suggest that using retinoids with vitamin E leads to improvements of some side effects due to isotretinoin. However, vitamin E blood levels have not been reported previously in patients with acne treated with isotretinoin. We aimed to investigate the serum vitamin E levels before and after isotretinoin therapy in patients with acne.

Unusual localization of a common cutaneous neoplasm: basal cell carcinoma.

Basal cell carcinoma (BCC) is the most common form of the skin carcinomas and ultraviolet radiation is the major risk factor in the etiopathogenesis. However, reports of unusual sites for BCC are increased in the literature. Authors draw attention to possibility of other etiological agents for BCC like local trauma, ageing, ionizing radiation, arsenic, chronic inflammation, and immune deficiency.
