Topical spray of Wharton's jelly mesenchymal stem cells derived from umbilical cord accelerates diabetic wound healing.

Background And Aim: Cell-based therapy utilizing mesenchymal stem cells (MSCs) is currently being investigated as a therapeutic agent for chronic wounds. There is no evidence regarding effectiveness of the spray and local transfer of this cellular product in diabetic wound healing. Accordingly, the present study, using clinical, pathological and biometric parameters, investigated the effectiveness of the spray of these cells in the healing of diabetic wounds in rats.

Ichthyosis, psoriasiform dermatitis, and recurrent fungal infections in patients with biallelic mutations in PERP.

Background: Germline autosomal dominant and autosomal recessive mutations in PERP, encoding p53 effector related to PMP-22 (PERP), a component of epidermal desmosomes, have been associated with a spectrum of keratodermas. Monoallelic nonsense mutations cause Olmsted syndrome with severe periorificial keratoderma and palmoplantar keratoderma (PPK). Biallelic recessive frameshift and missense mutations are associated with milder forms of the disease, including generalised erythrokeratoderma and PPK.

Keratitis-ichthyosis-deafness syndrome: Phenotypic heterogeneity and treatment perspective of patients with p.Asp50Asn GJB2 mutation.

Keratitis-ichthyosis-deafness (KID) syndrome is caused by mutations in the GJB2 gene encoding connexin 26, a component of transmembrane hemichannels which form gap junction channels, critical for cell-cell communication. Here, we report two patients from two distinct families with KID syndrome with the same GJB2 mutation (p.Asp50Asn); in both cases the mutation was de novo, as the parents depicted the wild-type allele only.

Genital Lesions Masquerading as Condyloma Acuminata: A Case Series Report.

Herein we report three married women referred to Dermatology Clinic of Loghman Hakim Hospital, Tehran, Iran in 2017 for evaluation and treatment of genital warts. Two patients were complaining of flat-topped papules on their labia major and the third one was presented with asymptomatic papillary projections on her vestibule and inner aspect of both labia minora. Histological examination revealed the diagnosis of syringoma, lymphangioma circumscriptum (LC) and vestibular papillomatosis respectively.

Serum and tissue angiotensin-converting enzyme in patients with alopecia areata.

Background: Alopecia areata is an immune-dependent disorder characterized by the interaction of T-lymphocytes with follicular antigens. Recent studies have shown the existence of a local renin-angiotensin system in the skin, where angiotensin-converting enzyme (ACE) plays a role in autoimmunity and inflammation.

Aim: The objective of this study was to evaluate serum and tissue ACE activity in patients with alopecia areata.
