Anti-psoriatic effect of myeloid-derived suppressor cells on imiquimod-induced skin inflammation in mice.

Scand J Immunol 2018 Dec 13:e12742. Epub 2018 Dec 13.

Pharmicell Co, Ltd, 484, Dunchon-daero, Jungwon-gu, Seongnam, Gyeonggi-do, Korea.

Myeloid-derived suppressor cells (MDSCs) play an important role in controlling the immune response against cancer and in suppression of autoimmunity and allergic inflammation. However, the beneficial effects of MDSCs on the experimental mouse model of psoriasis have not been reported. Therefore, we investigated the anti-psoriatic effect of MDSCs on IMQ-induced skin inflammation in mice and explored the mechanisms involved. Read More

Novel compound heterozygous FATP4 mutations caused ichthyosis prematurity syndrome in Spanish sisters.

Acta Paediatr 2018 Dec 11. Epub 2018 Dec 11.

Fundación Pública Galega de Medicina Xenómica-SERGAS, CIBERER, IDIS, Grupo de Medicina Xenómica-Universidade de Santiago de Compostela, Santiago de CompostelaSpain.

Ichthyosis prematurity syndrome (IPS), or ichthyosis congenita type IV, is a rare syndromic form of autosomic recessive ichthyosis caused by mutations in fatty acid transport protein 4 (FATP4), also known as SLC27A4. Patients with a disrupted FATP4 gene are usually born prematurely with thick desquamating skin and other complications, such as neonatal asphyxia, eosinophilia and elevated serum immunoglobulin E levels. Symptoms become less severe after the first months of life, evolving to non-scaly ichthyosis with follicular hyperkeratosis in adulthood (1, 2). Read More

Breast Cancer Metastasis in the Skin with Hyperkeratotic Pigmentation Caused by Melanocyte Colonization.

Case Rep Oncol 2018 Sep-Dec;11(3):660-664. Epub 2018 Oct 23.

Department of Dermatology, Tohoku University Graduate School of Medicine, Sendai, Japan.

Pigmented breast cancer in the skin caused by nonneoplastic melanocytes of epidermal origin is a rare condition of metastasis from breast cancer, but the pathogenesis of this phenomenon is almost unknown. In this report, we describe a case of breast cancer metastasis in the skin with prominent hyperkeratotic pigmentation caused by nonneoplastic melanocyte colonization. Immunohistochemical staining revealed that the metastatic tumor cells produced IL-23, which is reported not only to induce IL-17 but also to inhibit cell apoptosis in breast cancer cells, which affects tumor progression.

Narrow band imaging in transoral laser microsurgery (TLM) in moderately advanced (T2, T3) glottic cancer.

Otolaryngol Pol 2018 Aug;72(5):17-23

Department of Otolaryngology, Head and Neck Surgery, Poznań University of Medical Sciences, Poznań, Poland.

Introduction: Treatment planning in T2, T3 laryngeal carcinoma is based on clinical assessment and radiological imaging. However, to delineate precise mucosal margins for transoral laser microsurgery (TLM), a high class, sophisticated endoscopy is indispensable. Narrowband imaging (NBI) which is an optical filter technology, seems to be a useful adjunctive tool in marking superficial margins. Read More

Painful punctate palmoplantar keratoderma due to heterozygous mutations in AAGAB.

Br J Dermatol 2018 Nov 19. Epub 2018 Nov 19.

Dermatology and Genetic Medicine, Division of Biological Chemistry and Drug Discovery, School of Life Sciences, University of Dundee, Dundee, UK.

Punctate palmoplantar keratoderma (PPPK) is a rare, autosomal dominant disorder of keratinization with three main variants. PPPK type 1 (MIM 148600), also known as Buschke-Fischer-Brauer disease, is characterized by the progressive development of multiple small hyperkeratotic papules with central indentations that are irregularly distributed on the palms and soles, often deteriorating to more extensive diffuse hyperkeratosis on the weight-bearing areas of plantar skin. The PPPK1 gene was recently identified as the α and γ-adaptin binding protein p34 gene AAGAB, and in a single case, the COL14A1 gene. Read More

HPV-related oral dysplasia in a multiple myeloma patient after stem cell transplantation.

Spec Care Dentist 2018 Nov 15. Epub 2018 Nov 15.

Oral and Maxillofacial Diagnostic Sciences, University of Florida College of Dentistry, Gainesville, Florida.

The development of dysplastic changes in oral epithelial lesions is a potential long-term complication after hematopoietic stem cell transplantation (HSCT). This may be related to mechanisms including radiation and chemotherapy regimens, chronic graft-versus-host disease (cGVHD), inflammation, and prolonged immunosuppression. The current case describes a 54-year-old male with multiple myeloma treated by autologous and allogenic HSCT followed by development of cGVHD (mouth, skin and the eyes) with the complaint of diffuse white lesions on the buccal mucosa, tongue, and palate.

Philip R Cohen

Skin Appendage Disord 2018 Oct 26;4(4):331-334. Epub 2018 Mar 26.

Department of Dermatology, University of California San Diego, La Jolla, California, USA.

Half-and-half nails were originally described as a transverse leukonychia in patients with chronic renal disease; other conditions (such as Behcet's and Crohn's disease) and medications (such as isoniazid) have also been associated with the nail changes. However, longitudinal half-and-half nails (affecting the medial aspects of the nails) have previously been reported on the great toes of an older woman and, in the present case, on the thumbs of an elderly man; neither person had Behcet's, Crohn's, or kidney disease or was receiving isoniazid. The woman had a true leukonychia, bilateral hallux valgus deformity, and chronic trauma to her medial nail folds. Read More

Vet Parasitol 2018 Sep 5;261:96-103. Epub 2018 Sep 5.

Universidade Federal de São João del-Rei (UFSJ), Campus Centro-Oeste Dona Lindu, Divinópolis, MG, Brazil. Electronic address:

Canine visceral leishmaniosis (CVL), a parasitic disease caused by Leishmania infantum, may evolve to a chronic condition and lead to death. Evaluation of infected dogs is important to establish the clinical and laboratory parameters involved in the evolution of the disease. The objectives of the present study were to discriminate a canine population (n = 52) into sub-clinical and clinically affected dogs based on signs and scores, to evaluate the hematological, biochemical, histopathological and parasitological parameters of the two dog groups, and to analyze the results by multivariate regression analysis with the aim of establishing biomarkers of CVL clinical disease.

An 8-year-old girl presented with a persistent 5 × 2-cm violaceous doughy plaque on the left lower leg. Histologic examination revealed hyperkeratosis, variable but mild epidermal hyperplasia, and vacuolar interface changes with melanin pigment incontinence confined to the papillary dermis. A diagnosis of pretibial lymphoplasmacytic plaque in children was made. Read More

Ectopic transglutaminase 1 and 3 expression accelerating keratinization in oral lichen planus.

J Int Med Res 2018 Nov 13;46(11):4722-4730. Epub 2018 Sep 13.

2 Hard Tissue Pathology Unit, Graduate School of Oral Medicine, Matsumoto Dental University, Nagano, Japan.

Objective: Oral lichen planus (OLP) characterized by interface mucositis frequently shows hyper-keratinization. To clarify mechanisms of excess keratinization, we investigated key molecules for cornified cell envelope (CE).

Methods: Involucrin (IVL), loricrin (LOR), transglutaminase 1 (TGase 1) and transglutaminase 3 (TGase 3) were immunohistochemically examined in 20 specimens of OLP; five specimens of buccal mucosa served as controls. Read More
