Outbreaks of infectious diseases may occur in animal and human populations; this underlines the need for suitable One Health approaches. During outbreak situations, straightforward identification of etiological agents is indispensable for taking countermeasures. A recently published protocol for metagenomic virus detection in clinical specimens (TUViD-VM) was developed for snap-frozen tissues which can be challenging to obtain. Here, we describe the use of RNALater(®) -treated tissue at ambient temperatures for virome sequencing...

The objective of the present work was to present the results of the clinical analysis of the patient presenting with natural killer (NK)/T-cell lymphoma of the nasal type. We undertook the analysis of the medical documentation concerning the case of interest. It was shown that the development of progressive perforation of the nasal septum and the pronounced destructive changes in the intranasal and adjacent structures following the endonasal surgical interventions made necessary differential diagnostics between the condition under consideration and certain latent disorders (such as Wegener's granulomatosis, leprosy, syphilis, leishmaniasis, dirofilariasis tuberculosis, etc...

Human noroviruses (HuNoV), members of the family Caliciviridae are the major cause of acute viral gastroenteritis worldwide. Successful infection is linked to the ability of the protruding (P) domain of the viral capsid to bind histo-blood group antigens (HBGA). Binding to gangliosides plays a major role for many non-human calici- and noroviruses. Increasing evidence points to a broader role of sialylated carbohydrates such as gangliosides in norovirus infection. Here, we compare HBGA and ganglioside binding of a GII...

The rapid and sustained antidepressant properties of ketamine provide evidence of the importance of the glutamatergic system in the neurobiology of depression. The antidepressant-like effects of ketamine are dependent on brain-derived neurotrophic factor (BDNF) and mammalian target of rapamycin (mTOR) in limbic brain areas. The nitrergic system is closely related to the glutamatergic system and generates antidepressant-like effects when blocked. The aim of this study was to investigate whether the behavioural effects induced by the inhibition of nitric oxide (NO) synthesis by aminoguanidine or N-methyl-D-aspartate (NMDA) receptor blockade by ketamine would affect the gene expression of Bdnf and Mtor in the ventromedial prefrontal cortex in rats...

Finding, testing and demonstrating efficacy of new treatments for stroke recovery is a multifaceted challenge. We believe that to advance the field, neurorehabilitation trials need a conceptually rigorous starting framework. An essential first step is to agree on definitions of sensorimotor recovery and on measures consistent with these definitions. Such standardization would allow pooling of participant data across studies and institutions aiding meta-analyses of completed trials, more detailed exploration of recovery profiles of our patients and the generation of new hypotheses...

REVIEW
E Héron, T Bourcier
Episcleritis is generally a benign disease with a self-limited course, while scleritis is a severe ocular condition due to a risk of impaired vision in one-fifth of patients and its association with systemic diseases in one third of them. Infectious scleritis, representing 8 % of the etiologies, is mainly of herpetic origin (varicella zoster and herpes simplex viruses). A systemic autoimmune disease is observed in roughly 30 % of scleritis patients: inflammatory rheumatisms (15 %), firstly rheumatoid polyarthritis, systemic vasculitides (8 %), mainly granulomatosis with polyangiitis (Wegener's) and polychondritis, and less often inflammatory bowel disease and systemic lupus erythematosus...

Granulomatosis with polyangiitis (GPA), previously known as Wegener's granulomatosis, is a pulmonary-renal syndrome affecting small and medium sized blood vessels. The disease has a prevalence in studies ranging from 3 to 15.7 cases per 100,000, with a noted increasing incidence and prevalence in more recent studies. Pulmonary manifestations include hemorrhage, lung cavitary lesions, and pulmonary fibrosis. Within the kidney, GPA is known to cause rapidly progressive pauci-immune crescentic glomerulonephritis...

BACKGROUND: Patients who have granulomatosis with polyangiitis (GPA, syn. M. Wegener) often develop an external nose deformity which may have devastating psychological effects. Therefore, reconstruction of nasal deformities by rhinoplasty may become necessary to achieve a normal appearance. OBJECTIVE OF REVIEW: The aim of this systematic review was to investigate the efficacy and safety of surgical reconstruction in external nasal deformities and septal perforation in GPA patients...

Autoantibodies play an important role in the pathophysiology of renal involvement in systemic autoimmune diseases, such as systemic lupus erythematosus (SLE), systemic vasculitis, and anti-glomerular basement membrane disease (or Goodpasture syndrome). Direct removal of autoantibodies therefore has been tried in various ways, first by plasma exchange. Today, immunoadsorption is the extracorporeal method that most effectively removes (pathogenic) immune complexes and antibodies. Although past data have shown efficacy and biocompatibility of immunoadsorption in (renal) SLE, it is still an experimental and expensive procedure, and evidence from randomized controlled trials is needed...

ANCA vasculitis has an associated autoimmune response that produces ANCAs that induce distinct pathologic lesions. Pauci-immune necrotizing and crescentic GN is a frequent component of ANCA vasculitis. ANCA vasculitis is associated with ANCA specific for myeloperoxidase (MPO-ANCA) or proteinase 3 (PR3-ANCA). A diagnosis of ANCA vasculitis should always specify the serotype as MPO-ANCA positive, PR3-ANCA positive, or ANCA-negative. To fully characterize a patient, the serotype also should be accompanied by the clinicopathologic variant if this can be determined: microscopic polyangiitis, granulomatosis with polyangiitis (Wegener), eosinophilic granulomatosis with polyangiitis (Churg-Strauss), or renal-limited vasculitis...

Many etiologies are held accountable for nasal septum perforations. Topical nasal drug usage, previous surgeries, trauma, nose picking, squamous cell carcinoma, some rheumatological disorders such as granulomatosis with polyangiitis (Wegener granulomatosis), some infectious diseases such as syphilis and leprosy are among the causes of the perforations. Occupational heavy metal exposures by inhalation rarely may also cause nasal septum perforation. Here, we present a 29-year-old patient without any known diseases, who is a worker at a metallic coating and nickel-plating factory, referred for investigation of his nasal cartilage septum perforation from an otorhinolaryngology clinic...

Wegener's granulomatosis (WG) is characterized by necrotizing polyangiitis involving the respiratory tract and kidneys. It causes segmental necrotizing glomerulonephritis in the kidneys. In rare cases, a renal pseudotumor may be seen because of the granulomatous process. Association of WG with renal malignancy, however, is very uncommon. We report a case of a patient who presented several years after being treated for WG with malignant hypertension and an infiltrating mass in the right kidney. The histopathology of radical nephrectomy specimen showed presence of primitive neuroectodermal tumor (PNET)...

Understanding the processes that are driving variation of natural microbial communities across space or time is a major challenge for ecologists. Environmental conditions strongly shape the metabolic function of microbial communities; however, other processes such as biotic interactions, random demographic drift or dispersal limitation may also influence community dynamics. The relative importance of these processes and their effects on community function remain largely unknown. To address this uncertainty, here we examined bacterial and archaeal communities in replicate 'miniature' aquatic ecosystems contained within the foliage of wild bromeliads...
