A New Cixiid Fossil Genus of the Tribe Acrotiarini from Mid-Cretaceous Burmese Amber (Insecta, Hemiptera, Fulgoromorpha).

Insects 2022 Jan 17;13(1). Epub 2022 Jan 17.

Institut de Systématique, Evolution, Biodiversité, ISYEB-UMR 7205 MNHN-CNRS-Sorbonne Université-EPHE-Univ. Antilles, Muséum National d'Histoire Naturelle, CP 50, 57 rue Cuvier, 75005 Paris, France.

A new Burmese amber genus with its type species is described in the planthopper family Cixiidae. This new genus is unique in Burmese Cixiidae by its forewing venation, with Pcu and A1 merging in the middle of clavus, the late bifurcation of ScP+R slightly after this level, and the early CuA forking well before this level. Although the head capsule is missing, it belongs to the recently described tribe Acrotiarini, based on the pentacarinated mesonotum and the distinctly arched RA on forewing with cell C1 wider submedially than apically.

A computational model of the epidermis with the deformable dermis and its application to skin diseases.

Sci Rep 2021 06 24;11(1):13234. Epub 2021 Jun 24.

Research Center of Mathematics for Social Creativity, Research Institute for Electronic Science, Hokkaido University, Sapporo, Japan.

The skin barrier is provided by the organized multi-layer structure of epidermal cells, which is dynamically maintained by a continuous supply of cells from the basal layer. The epidermal homeostasis can be disrupted by various skin diseases, which often cause morphological changes not only in the epidermis but in the dermis. We present a three-dimensional agent-based computational model of the epidermis that takes into account the deformability of the dermis. Read More

Relationship Between Plantar Callosity and Foot Deformity in Hallux Valgus Using Weightbearing Computed Tomography.

J Foot Ankle Surg 2021 Nov-Dec;60(6):1207-1211. Epub 2021 May 26.

Department of Orthopaedic Surgery, Sapporo Medical University School of Medicine, Sapporo, Japan.

Plantar callosities under lesser metatarsals are often accompanied by the hallux valgus, and the cause of callosity is thought to be associated with the foot deformity, such as the metatarsal length discrepancy, the abnormal metatarsal head height, cavus, flat foot, and rheumatoid conditions. However, it is unclear which variable is most involved in the cause of callosity in hallux valgus deformity. To clarify the factors associated with the callosity with hallux valgus deformity, we conducted multiple image assessments based on weightbearing radiography and computed tomography. Read More

Periwound skin care considerations for older adults.

Br J Community Nurs 2021 Jun;26(Sup6):S26-S33

Senior Tissue Viability Nurse and Clinical Operational programme improvement Lead, Welsh Wound Innovation Centre.

This article discusses the effects of ageing on the skin, particularly the main structural and functional changes that occur in the epidermis and dermis that make the skin more vulnerable to damage. Specific alterations that occur with ageing include slower epidermal turnover, flattening of the epidermal-dermal junction, loss of moisture and hydration as well as reduced immunity placing the skin at increased risk of damage. The discussion will also examine common periwound complications associated with ageing including; maceration, excoriation, dry skin, hyperkeratosis, callus, contact dermatitis and eczema. Read More

J Foot Ankle Res 2021 Apr 13;14(1):30. Epub 2021 Apr 13.

Department of Physical Activity Sciences and Podiatric Medicine, Université du Québec à Trois-Rivières, 3351, boul. des Forges, C.P. 500, Trois-Rivières, G9A 5H7, Canada.

Background: An intractable plantar keratoma (IPK) is a conical thickening of the epidermis' stratum corneum and a common cause of foot pain which can have a significant, detrimental impact on the mobility, quality of life and independence of individuals. Conservative treatments are currently offered to patients with IPK, but they are unsatisfactory since they do not offer a sufficient or permanent reduction of symptoms. The purpose of this study was the evaluation of the feasibility, safety and effectiveness of innovative treatments for intractable plantar keratoma (IPK). Read More
