Alexithymia in different dermatologic patients.

Alexithymia is a personality trait characterized by difficulties in differentiating and describing feelings. Research indicates that alexithymia can be considered as a possible risk factor for a variety of medical conditions. The purpose of our study was to compare and assess the prevalence of alexithymia in patients with psoriasis, alopecia areata, vitiligo and acne vulgaris.

Assessment of clinical diagnostic accuracy compared with pathological diagnosis of basal cell carcinoma.

Background: Basal cell carcinoma (BCC) is the most common type of skin cancer, afflicting light skin more than dark skin people. This malignancy metastasizes rarely and has unique histological properties.

Aims And Objectives: We focused on the accuracy of clinical diagnoses of BCC by specialists.

Familial amyloidosis cutis dyschromica: a case report.

Amyloidosis cutis dyschromica (ACD) is a rare form of macular amyloidosis characterized by hypo and hyperpigmented macules. Here we described a 20 year old girl with diffuse hypo and hyperpigmentation since she was four years old. Five other members of her family are also involved.

Comparison of Q-Switched 1064-nm Nd: YAG laser and fractional CO2 laser efficacies on improvement of atrophic facial acne scar.

Background: Acne scarring is treatable by a variety of modalities. Ablative carbon dioxide laser (ACL), while effective, is associated with undesirable side effect profiles. Newer modalities using the principles of fractional photothermolysis (FP) produce modest results than traditional carbon dioxide (CO(2)) lasers but with fewer side effects.

Is topical nitric oxide and cryotherapy more effective than cryotherapy in the treatment of old world cutaneous leishmaniasis?

Background: Current systemic treatments for cutaneous leishmaniasis are limited by their toxicity, high cost, side effects and the emergence of drug resistance. New approaches, including topical therapies, are urgently needed. Nitric oxide (NO) produced by human and canine macrophages has long been demonstrated to be involved in the intracellular killing of Leishmania.

Association of interferon-gamma and tumor necrosis factor alpha polymorphisms with susceptibility to vitiligo in Iranian patients.

Vitiligo is a common skin disorder that is caused by selective destruction of melanocytes, resulting in disfiguring loss of pigment. There are convincing evidences that cytokines and T cell mediated immunity may have a role in its pathogenesis. Given the fact that cytokine production is under genetic control, in this study, we have investigated IFN-gamma +874 T/A and TNF-alpha -308 G/A gene polymorphisms in a total of 176 vitiligo patients and 545 controls.
