OBJECTIVES: Prompt treatment for lupus is important to prevent morbidity. A potential barrier to early treatment of pediatric lupus is delayed presentation to a pediatric rheumatologist. To better understand factors contributing to delayed presentation among pediatric lupus patients, we examined differences in demographic and clinical characteristics of lupus patients within the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Legacy Registry with regards to time between symptom onset and presentation to a pediatric rheumatologist...

We report a case of rapidly progressive glomerulonephritis caused by anti-glomerular basement membrane (GBM) disease accompanied by systemic lupus erythematosus (SLE) presenting central nervous system involvement in a 32-year-old Japanese male. He was admitted to our hospital because of a 3-week history of fever and rapidly failing renal function requiring hemodialysis (HD). Laboratory tests showed anti-GBM antibody elevation with a value of 16,385 units/ml. On day 85, he had generalized tonic-clonic seizure...

To inform our ongoing efforts to develop defining features to be incorporated into a novel set of classification criteria for discoid lupus erythematosus (DLE), we conducted a literature review using the Ovid MEDLINE database. A search was performed to identify studies reporting criteria used to distinguish DLE from other cutaneous lupus erythematosus subtypes. We examined which clinical, histopathologic, and serologic features have data to support their use as effective features in distinguishing DLE from other potential disease mimickers and cutaneous lupus subsets...

Currently, no standardized classification criteria exist for cutaneous lupus erythematosus. With increased interest in studying cutaneous lupus erythematosus, specifically discoid lupus erythematosus, it is our aim to apply previously adopted methods from rheumatology to dermatologic diseases to develop feasible, validated, and standardized classification criteria useful in both academic and community practice. Here we report the progress to date to define discoid lupus erythematosus using clinical, histopathologic, and serologic features by means of a Delphi method-using a series of iterative questionnaires sent to expert stakeholders...

Cutaneous lupus erythematosus(CLE) can be an individual disease only involving skin, or presents as part of the manifestations of SLE. A small proportion of CLE may progress into SLE, however, the underlying pathogenic mediators remain elusive. By only including researches that clearly described if the subtypes of CLE presented by enrolled subjects was associated with or without SLE, we provided an overview of antibodies, inflammatory cells and inflammatory molecular mediators identified in blood and skin that were possibly involved in lupus skin damages...

Background Epidemiological studies in systemic lupus erythematosus have been reported in the literature in many countries and ethnic groups. Although systemic lupus erythematosus in Jamaica has been described in the past, there has not been a detailed evaluation of systemic lupus erythematosus patients in urban Jamaica, a largely Afro-Caribbean population. The goal of this study was to describe the clinical features, particularly disease activity, damage index and immunological features, of 150 systemic lupus erythematosus subjects...

Systemic lupus erythematosus (lupus, SLE) is a chronic autoimmune disease characterized by the production of autoantibodies, which bind to antigens and are deposited within tissues to fix complement, resulting in widespread systemic inflammation. The studies presented herein are consistent with hyperpolarized, adenosine triphosphate (ATP)-deficient mitochondria being central to the disease process. These hyperpolarized mitochondria resist the depolarization required for activation-induced apoptosis. The mitochondrial ATP deficits add to this resistance to apoptosis and also reduce the macrophage energy that is needed to clear apoptotic bodies...

BACKGROUND: Discoid lupus erythematosus (DLE) is a chronic form of cutaneous lupus, which can cause scarring. Many drugs have been used to treat this disease and some (such as thalidomide, cyclophosphamide and azathioprine) are potentially toxic. This is an update of a Cochrane Review first published in 2000, and previously updated in 2009. We wanted to update the review to assess whether any new information was available to treat DLE, as we were still unsure of the effectiveness of available drugs and how to select the most appropriate treatment for an individual with DLE...

INTRODUCTION: Mucosal involvement is commonly seen in patients with lupus; however, oral examination is often forgotten. Squamous cell carcinoma arising within oral lupoid plaques has been described, emphasizing the importance of identifying and treating oral lupus. METHODS: We undertook a retrospective single-centre study looking at oral findings in patients attending our multidisciplinary lupus clinic between January 2015 and April 2016. RESULTS: A total of 42 patients were included...

PURPOSE: Symptomatic discoid lateral meniscus without tears has traditionally been treated with excision of part or the entire meniscus. Resection of 15-34% of the meniscus increases tibiofemoral contact pressures by more than 350%. Treatment of discoid lateral meniscus with partial or total meniscectomy in childhood increases the risk of early-onset osteoarthritis in the knee. The incidence of osteoarthritis is directly proportional to the amount of meniscal tissue resected. This paper describes the meniscus-preserving technique of meniscopexy and presents the outcomes of all patients who have undergone this procedure in the management of lateral discoid meniscus in a single unit over a 14-year period...

Background and Aims: Ultrathin sections of rice leaf blades observed two-dimensionally using a transmission electron microscope (TEM) show that the chlorenchyma is composed of lobed mesophyll cells, with intricate cell boundaries, and lined with chloroplasts. The lobed cell shape and chloroplast positioning are believed to enhance the area available for the gas exchange surface for photosynthesis in rice leaves. However, a cell image revealing the three-dimensional (3-D) ultrastructure of rice mesophyll cells has not been visualized...

Arcellinid testate amoebae include a wide variety of amoeboid organisms whose test (shell) varies in shape, composition and size. A decade ago, we initiated molecular phylogenetic analyses based on SSU rRNA gene sequences and a taxonomic revision of Arcellinida. However, many lineages within Arcellinida still lack molecular data, and the phylogeny of this group is largely incomplete. In this study, we obtained SSU rRNA gene sequences from seven taxa, of which six have agglutinated shell (Difflugia oblonga, D...

To investigate in a long-term study, the development of new extra-glandular manifestations (EGM) or associated auto-immune diseases (AID) from 1 year after establishing the diagnosis of primary Sjögren's syndrome (pSS). The primary goal was to examine the frequency and type of these manifestations and to find out which demographic, clinical and serological profile was most at risk. All outpatients diagnosed with primary Sjögren's syndrome were included in a retrospective study, with at least one check-up per year, from June 1991 until August 2015...

Synapsida, the clade including therapsids and thus also mammals, is one of the two major branches of amniotes. Organismal design, with modularity as a concept, offers insights into the evolution of therapsids, a group that experienced profound anatomical transformations throughout the past 270 Ma, eventually leading to the evolution of the mammalian bauplan. However, the anatomy of some therapsid groups remains obscure. Gorgonopsian braincase anatomy is poorly known and many anatomical aspects of the brain, cranial nerves, vasculature, and osseous labyrinth, remain unclear...

CONTEXT: Discoid lupus erythematosus (DLE) and human immunodeficiency virus (HIV) are both disorders of the immune system. The pathophysiology of these diseases varies greatly as DLE is characterized by an overactive immune system that attacks normal host cells, whereas HIV is characterized by an exogenous attack on the immune system that depletes it of key cell types. Although the reason is unknown, co-occurrence of DLE and HIV is rare. AIMS: The goal of this study is to determine the prevalence of co-occurrence of DLE and HIV and to determine whether patients with both DLE and HIV share any clinical feature...

The Ediacara biota features the rise of macroscopic complex life immediately before the Cambrian explosion. One of the most abundant and widely distributed elements of the Ediacara biota is the discoidal fossil Aspidella, which is interpreted as a subsurface holdfast possibly anchoring a frondose epibenthic organism. It is a morphologically simple fossil preserved mainly in siliciclastic rocks, which are unsuitable for comprehensive stable isotope geochemical analyses to decipher its taphonomy and paleoecology...

The pelvic skeleton is formed via endochondral ossification. However, it is not known how the normal cartilage is formed before ossification occurs. Furthermore, the overall timeline of cartilage formation and the morphology of the cartilage in the pelvis are unclear. In this study, cartilage formation in the pelvic skeletons of 25 human fetuses (crown-rump length [CRL] = 11.9-75.0 mm) was observed using phase-contrast computed tomography and 7T magnetic resonance imaging. The chondrification center of the ilium, ischium, and pubis first appeared simultaneously at Carnegie stage (CS) 18, was located around the acetabulum, and grew radially in the later stage...

In their early stages, some dermatoses of the scalp such as psoriasis seborrheic dermatitis, tinea capitis and discoid lupus erythematosus are often hardly noticeable to others. However, the eruptions are occasionally severe and extensive. Reaching an adequate diagnosis is of utmost impor¬tance for an adequate healthcare.

Tubular vesicles represent abundant structural motifs which are observed both in experiments and in nature. We analyse them within the theory of bending elasticity and determine the equilibrium solutions at fixed volume, surface area, and segment length without imposing any specific symmetry or periodicity. We identify four different non-periodic equilibrium shapes. Depending on the precise value of the constraints or the corresponding Lagrange multipliers, these four shapes include: (i) snake-like and (ii) helical structures, (iii) tubes with a spherical body, and (iv) tubes with a discoidal body...
