BACKGROUND: Spinal intradural arachnoid cysts (SIAC) are cerebrospinal fluid (CSF) filled sacs formed by arachnoid membranes and may be either idiopathic or acquired. Idiopathic cysts represent a separate entity and their aetiology remains uncertain. By far the most difficult differential diagnosis is distinguishing between idiopathic anterior spinal cord herniation (IASCH) and dorsal thoracic intradural arachnoid cysts (TIAC), due to their similarity in radiological appearance. Cine-mode (SSFP) is emerging as a novel technique in the diagnosis and operative planning of SIAC...

Primary membranous nephropathy (PMN) is characterized by antibodies to the podocyte, but little is known about B- and T-cell populations and their response to rituximab is controversial. To help resolve this we compared 33 lymphocyte subpopulations and 27 cytokines/chemokines in 25 patients with severe PMN and 27 age-matched healthy individuals. At baseline, patients had a significantly increased percentage of naive B-cells with significantly decreased switched and non-switched memory B-cells. There was a significantly decreased percentage of natural killer (NK) cells with an increase in the CD56(bright)CD16(-/lo) NK subset...

Vitreopapillary traction (VPT) is an unusual clinical entity and its management and prognosis have been sparsely studied. It has been described in adults with various vitreomacular pathologies and the possible effects on visual functions. However, the role of surgical intervention in altering the course of the disease is not well understood. Hereby, we describe a case of idiopathic VPT in a 16-year-old girl who presented with decreased vision and visual field changes corresponding to the area of retinal traction...

Anhidrosis/hypohidrosis are conditions presenting various level of sweating dysfunction. Among them, acquired idiopathic generalized anhidrosis (AIGA) presents inadequate decrease or loss of sweating without apparent neurological and dermatological symptoms except cholinergic urticaria. Recently, serum level of carcinoembryonic antigen (CEA), one of the most well-known tumor markers, has been proposed as a clinical marker reflecting activity of AIGA. This study was performed to verify the specificity and independence of serum CEA level from the other serum tumor markers especially related to adenocarcinoma...

Lesley J Scott
Sarilumab (Kevzara™) is a fully human IgG1 monoclonal antibody that binds specifically to both soluble and membrane-bound interleukin (IL)-6 receptors (sIL-6Rα and mIL-6Rα) and thereby inhibits IL-6-mediated signalling through these receptors. Subcutaneous sarilumab is approved in Canada for the treatment of adult patients with moderately to severely active rheumatoid arthritis who have had an inadequate response to one or more biological or non-biological disease-modifying anti-rheumatic drugs. It is under regulatory review for use in rheumatoid arthritis in other countries, including in the EU, USA and Japan...

In lung injury and disease, including idiopathic pulmonary fibrosis (IPF), extravascular factor X is converted into factor Xa (FXa), a coagulant protease with fibrogenic actions. Extracellular annexin A2 binds to FXa, augmenting activation of the protease activated receptor-1 (PAR-1). In this study, the contribution of annexin A2 in lung injury and fibrosis was investigated. Annexin A2 immunoreactivity was observed in regions of fibrosis, including associated with fibroblasts in lung tissue of IPF patients...

Choroidal neovascularisation (CNV) in the context of exsudative age-related macular degeneration (nAMD) can be divided into type 1 (occult) and type 2 (classical) membranes. Retinal angiomatous proliferation (RAP) or polypoidal choroidal vasculopathy (PCV) are "rare subtypes" of chorioretinal neovascularisation and are distinguished by their distinct morphology and the sometimes worse response to therapy. Chorioretinal anastomosis, severe exsudates with serosanguinous pigment epithelial detachment and, in PCV, orange-red lesions in the papillomacular bundle can be diagnostic...

Receptor-associated prorenin system (RAPS) refers to the pathogenic mechanism whereby prorenin binding to (pro)renin receptor [(P)RR] dually activates tissue renin-angiotensin system (RAS) and RAS-independent signaling via (P)RR. The aim of this study is to determine the association of RAPS with idiopathic epiretinal membrane (iERM). Reverse transcription-PCR indicated the expression of RAPS components, including (P)RR and Ang II type 1 receptor (AT1R), in iERM tissues and human Müller glial cell line. Double-labeling analyses demonstrated that (P)RR and AT1R were detected in cells positive for glial fibrillary acidic protein, a marker for glial cells, and co-localized with prorenin and angiotensinogen, respectively...

There are two basic pathways for formation of calcium based kidney stones. Most idiopathic calcium oxalate (CaOx) stones are formed in association with sub-epithelial plaques of calcium phosphate (CaP), known as Randall's plaques, on renal papillary surfaces. Crystal formation and retention within the terminal collecting ducts, the ducts of Bellini, leading to the formation of Randall's plugs, is the other pathway. Both pathways require supersaturation leading to crystallization, regulated by various crystallization modulators produced in response to changing urinary conditions...

BACKGROUND: Suggestion for the management of idiopathic membranous nephropathy (IMN) includes 6 months of observation, followed with steroid plus alkylating agent. However, delayed immunosuppression exposes the kidneys to persistent damage. This study aimed to examine the benefit of early immunosuppression in IMN patients. METHOD: A retrospective study was performed. From 1993 to 2013, 161 IMN patients were enrolled. Patients receiving immunosuppression within 6 months after diagnosis were classified as initial-treatment group, whereas other patients as initial-no-treatment group...
