Barbara Nieradko-Iwanicka
Psoriasis is a chronic recurrent inflammatory skin disease with prevalence of 1-3%. Nail psoriasis affects 10-90% of patients with plaque psoriasis. The aim of the article is to review the literature for the correlation between nail psoriasis and psoriatic arthritis (PsA) to provide rheumatologists a short review on features of nail psoriasis, methods of their assessment and possible clinical repercussions. The PubMed database was searched using the key words 'nail psoriasis' and 'psoriatic arthritis'. Psoriasis involving the nail matrix shows up as changes such as pitting, Beau lines, leukonychia, red spots in the lunula, or nail plate crumbling...

INTRODUCTION: Redness of the nail plate-erythronychia-is a common condition involving one or multiple digits. It may affect the entire nail or present as longitudinal red bands that extend from the proximal nail fold to the distal tip of the nail plate. Rarely, red bands may traverse the nail bed horizontally. Although erythronychia is often idiopathic, it has also been associated with amyloidosis, Darier's disease, lichen planus, and various other cutaneous conditions. We describe the clinical features of a 64-year-old Caucasian man who presented with transverse and longitudinal erythronychia affecting his fingernails...

Alopecia areata (AA) is a chronic, autoimmune disease. The main symptom is massive hair loss, localized or diffuse, in the scalp and the whole body. However, nails may also be involved, and brittleness, fragility and pitting can be signs of nail dystrophy in AA patients. Here, we report the case of a male patient with AA refractory to various treatments, including oral, topical and intralesional corticosteroids, immunosuppressants, cyclosporin and PUVA (oxoralen plus ultraviolet light), all interrupted due to side effects...

Sesamoids bones are small intra-tendinous (or ligamentous) ossifications found near joints and are often variable between individuals. Related bones, lunulae, are found within the menisci of certain joints. Several studies have described sesamoids and lunulae in lizards and their close relatives (Squamata) as potentially useful characters in phylogenetic analysis, but their status in the extant outgroup to Squamata, tuatara (Sphenodon), remains unclear. Sphenodon is the only living rhynchocephalian, but museum specimens are valuable and difficult to replace...

INTRODUCTION: The anatomy and embryology of the nail are well known, and nail abnormalities are a feature of many genodermatoses. However, the physiological aspect is not well described. We aimed to analyse the physiological features of nails in healthy newborns. METHODS: We performed an observational, prospective study at University Hospital Center of Tours between July and October 2015. Newborns were included by a dermatologist assistant during the systematic examination on release of the mother from the hospital...

BACKGROUND: Vitiligo is an acquired pigmentary skin disorder affecting 0.1-4% of the general population. The nails may be affected in patients with an autoimmune disease such as psoriasis, and in those with alopecia areata. It has been suggested that nail abnormalities should be apparent in vitiligo patients. OBJECTIVE: We sought to document the frequency and clinical presentation of nail abnormalities in vitiligo patients compared to healthy volunteers. We also examined the correlations between nail abnormalities and various clinical parameters...

We studied the monogenean communities of 34 species of butterflyfish from the tropical Indo-West Pacific, identifying 13 dactylogyrid species (including two species that are presently undescribed). Monogenean assemblages differed significantly between host species in terms of taxonomic structure, intensity and prevalence. Parasite richness ranged from 0 (Chaetodon lunulatus) to 11 (C. auriga, C. citrinellus and C. lunula). Host specificity varied between the dactylogyrids species, being found on 2-29 of the 34 chaetodontid species examined...

The classic chemical garden experiment is reconstructed to produce protein-intercalated silicate-phosphate tubules that resemble tubular sponges. The constructs were synthesized by seeding calcium chloride into a solution of sodium silicate-potassium phosphate and gelatin. Sponge-mimetic tubules were fabricated with varying percentages of gelatin (0-15% w/v), in diameters ranging from 200 μm to 2 mm, characterized morphologically and compositionally, functionalized with biomolecules for cell adhesion, and evaluated for cytocompatibility...

BACKGROUND: Nail-patella syndrome (NPS) is an inherited disease produced by mutations in the LMX1B gene. It is characterized by fingernail dysplasia, hypoplastic or absent patella, dysplasia of the elbows and iliac horns on X-ray. It is useful to know this syndrome since some patients develop nephropathy and eye abnormalities. There are very few accurate descriptions related to this syndrome in the literature. OBJECTIVE: Describe the features of 11 patients with NPS in a paediatric hospital...

Cutaneous leiomyomata, which are benign smooth muscle neoplasms, commonly present as dermal-based nodules or papules with smooth borders and firm consistency. Digital, particularly subungual leiomyomata are quite rare. A 16-year-old female presented to nail clinic complaining of discoloration of the lunula of the left thumbnail for 2.5 months. On initial examination, a pink longitudinal band was present in the center of the nail plate, with yellow discoloration and distal onycholysis. The patient had only mild tenderness with firm palpation, and did not recall trauma of the area...

Sediments in navigation-dominated waterways frequently are contaminated with a variety of particle-associated pollutants and are subject to frequent short-term resuspension events. There is little information documenting whether resuspension of metal-contaminated sediments has adverse ecological effects on resident aquatic organisms. Using a novel laboratory approach, the authors examined the mobilization of Zn, Cu, Cd, Pb, Ni, and Cr during resuspension of 1 freshwater and 2 coastal marine sediments and whether resuspension and redeposition resulted in toxicity to model organisms...

The Iso-Kikuchi Syndrome is a rare condition characterized by nail dysplasia involving the index fingers, including micronychia, polyonychia, anonychia, irregular lunula, malalignment and hemionychogryphosis. On the antero-posterior image, radiologic examination reveals a narrowing of the distal phalanx. The lateral image shows a Y-shaped bifurcation of the distal phalanx. We report a case of a patient with typical clinical and radiologic signs of Iso-Kikuchi Syndrome.

OBJECTIVE: We report a case in which an avulsion-amputation of the thumb proximal to the lunula was repaired by reattaching the amputated segment as a composite graft. The graft demonstrated complete survival with only a minimal sacrifice in length. METHODS: A 23-year-old man presented 4 hours after an avulsion injury of the thumb with associated distal and proximal phalanx fractures. The amputated segment included the sterile and germinal matrix. He underwent defatting and composite grafting of the amputated segment followed by K-wire fixation of his proximal phalanx fracture...

REVIEW
Eshini Perera, Rodney Sinclair
"Nails protect the fingertips and toes. Diseases affecting the nail can cause cosmetic disfigurement and social embarrassment. Physical functioning may be impaired. Disorders of the nail bed may cause pain or create difficulty grasping fine objects. The nail bed is the area beneath the nail plate between the lunula and the hyponychium. Disorders of the nail bed can cause onycholysis, subungual hyperkeratosis, and/or onychogryphosis. Ventral pterygium is less common. Tumors of the nail bed are rare and commonly missed...

Cells are sophisticated integrators of mechanical stimuli that lead to physiological, biochemical, and genetic responses. The bioluminescence of dinoflagellates, alveolate protists that use light emission for predator defense, serves as a rapid noninvasive whole-cell reporter of mechanosensitivity. In this study, we used atomic force microscopy (AFM) to explore the relationship between cell mechanical properties and mechanosensitivity in live cells of the dinoflagellate Pyrocystis lunula. Cell stiffness was 0...
