A 66-year-old woman with a history of interstitial lung disease presented with a 3-month history of dropped head syndrome (DHS), followed by camptocormia and extremity weakness. A clinical examination revealed Raynaud phenomenon, arthralgia, distal skin sclerosis, and microbleeds in the nailfold capillaries. An anti-Ku antibody test was positive. A muscle biopsy revealed inflammatory myopathy with rimmed vacuoles (RVs). The diagnosis of scleroderma-polymyositis (SSc-PM) overlap syndrome was made. RVs on a muscle biopsy in a patient with inflammatory myositis involving axial muscles may be seen either in inclusion body myositis or SSc-PM overlap syndrome...

Microcirculation impairment and related vasculopathy is a hallmark of systemic sclerosis. Digital ulcers are second only to Raynaud's phenomenon as a vascular complication occurring in scleroderma patients. Digital ulcers are painful and generate disability. Furthermore, patients may develop recurrent digital ulcers and one may ask whether the outcomes of such patients might be different to those of unaffected ones. Recently several registries have provided relevant information about digital ulcers. Male sex and severe skin disease seem to be the main associated factors observed in several registries...

Systemic sclerosis (SSc) is an autoimmunological disease of unknown origin with complex pathogenesis and multiple organ involvement. It is characterised by vascular and immunological abnormalities leading to fibrosis of the skin and internal organs. It is a rather rare disease with a prevalence of around 20 per 100,000. The disease results in heterogeneous clinical findings and different courses. Systemic sclerosis usually begins with the onset of Raynaud's phenomenon (RP), followed by skin sclerosis and internal organ involvement, although it may appear synchronously with RP...

Background/Purpose: Serositis is one of both ACR and SLICC classification criteria for systemic lupus erythematosus (SLE) and a common type of extra renal flare. However, little is known about clinical or immunological associations of pleurisy or pericarditis. The aim of this study is to analyze associates and predictors of pleurisy versus pericarditis in Caucasians and African Americans with SLE. Methods: 2,390 SLE patients in the Hopkins Lupus Cohort were analyzed for demographic, clinical and serologic associates of pleurisy or pericarditis, defined using the SELENA revision of the SLE Disease Activity Index (SLEDAI)...

Introduction.Mycoplasma pneumoniae is a small cell-wall-lacking bacterium that belongs to the mycoplasma (Mollicutes) prokaryote micro-organisms. It is a common cause of both upper and lower respiratory tract infections in all age groups. Respiratory illness is the most common manifestation of M. pneumoniae infection; however, extrapulmonary involvement may be present or predominant. The skin, mucus membranes, central nervous system, cardiovascular system, haematopoietic system, kidneys and musculoskeletal system are the most commonly involved extrapulmonary sites...

Neuropilin-1 (NRP-1) is an extra-cellular receptor for the main Vascular Endothelial Growth Factor over-expressed in tumour tissues, VEGF-A165. Consequently, NRP-1 is involved in angiogenesis and in tumour growth, and its over-expression is related to a clinical poor prognosis. NRP-1 appears as a major target in oncology, which remains poorly exploited. Herein, we report a new series of 18 small-sized fully organic VEGF-A165/NRP-1 antagonists (NRPas). These compounds share an original scaffold, including two linkers (sulphonamide and amide) and three aromatic cores...

This case report describes a patient with scleroderma who developed Mycobacterium intracellulare infection, which for more than a year mimicked worsening of her connective tissue disorder. The patient was diagnosed with scleroderma based on puffy fingers that developed into sclerodactyly, abnormal nail fold capillaries, interstitial lung disease, Raynaud's phenomenon, esophageal dysmotility, and positivity for rheumatoid factor and anti-SSA antibodies. She developed massive inflammatory changes of the cutis, the subcutis, and the muscle fasciae of the right leg, that after several failed attempts of immunosuppressive treatments were found to be caused by Mycobacterium intracellulare...

Silicon solar cells have captured a large portion of the total market of photovoltaic devices mostly due to their relatively high efficiency. However, Silicon exhibits limitations in ultraviolet absorption because high-energy photons are absorbed at the surface of the solar cell, in the heavily doped region, and the photo-generated electron-hole pairs need to diffuse into the junction region, resulting in significant carrier recombination. One of the alternatives to improve the absorption range involves the use of down-shifting nano-structures able to interact with the aforementioned high energy photons...

BACKGROUND: Subclinical chronic inflammation could be the driving force behind the recently revealed association between abnormal nailfold capillaries as well as autoantibodies and long-term mortality in patients with incipient Raynaud's phenomenon. Whether laboratory markers that reflect a chronic inflammatory process are directly related to mortality in Raynaud's phenomenon is not known. METHODS: In total, 2958 patients with incipient Raynaud's phenomenon without previously known connective tissue disease (CTD) were enrolled...

Raynaud syndrome refers to a medical condition where arterial smooth muscle contraction induces blood flow reduction. Thermal images and questionnaires have been used to assess the efficacy of treatment. In this research, a potential way to measure whole-hand blood circulation in real-time using infrared image is introduced. Normalized average pixel intensity of the regions of interest in hand was measured during or after blood circulation changes brought by temperature alteration and pressure applied to the hand or forearm...

BACKGROUND: Since 2006, human papillomavirus (HPV) vaccines have been introduced in many countries worldwide. Whilst safety studies have been reassuring, focus has been on the primary target group, the young adolescent girls. However, it is also important to evaluate safety in adult women where background disease rates and safety issues could differ significantly. OBJECTIVE: We took advantage of the unique Danish and Swedish nationwide healthcare registers to conduct a cohort study comparing incidence rate ratios (RRs) of 45 preselected serious chronic diseases in quadrivalent HPV (qHPV)-vaccinated and qHPV-unvaccinated adult women 18-44 years of age...

Heparin-binding epidermal growth factor (EGF)-like growth factor (HB-EGF) is a member of the EGF family growth factors, which affects multiple aspects of the wound healing process such as epithelialization, wound contraction and angiogenesis. In our study, we measured the serum HB-EGF levels of 51 systemic sclerosis (SSc) patients, which showed a significant increase compared with those of 20 normal subjects. Further analysis revealed a positive correlation between the HB-EGF level and pulmonary ground-glass score but no correlation between the former and pulmonary fibrosis score...

RP is an exaggerated vasospastic response to cold or emotion. Randomized, double-blind, placebo-controlled trials with either parallel group or cross-over trials should be mainly considered. Cross-over design, which is good for early phase trials of immediate or very short-term outcomes, is important in a condition as heterogeneous as RP: a wash-out period between treatment arms should always be included to minimize the possibility of a period (carry-over) effect. Duration of RP trials is usually constrained by the need to complete these over a single season, usually winter when the weather is colder...

Raynaud phenomenon is an overactive vascular response to cold and emotional stress that results in cutaneous color changes and sensory symptoms in the digits. It can be idiopathic (primary) or secondary to another condition; the latter can be more severe and more apt to lead to ischemic complications such as digital ulceration and even loss of digits. If nonpharmacologic interventions prove inadequate, then vasodilator agents are used.
