A 5-yr-old, captive, hatched, female false gharial (Tomistoma schlegelii) presented with a 1-mo history of cervical spinal curvature. Antemortem diagnostics, including blood work, electromyography, muscle biopsies, and advanced imaging tests, were either within reference ranges or did not identify any specific etiology. Necropsy revealed extensive, marked, chronic granulomatous encephalomyelitis along with neuronal necrosis, rarefaction, gliosis, and astrocytosis of the white and gray matter of the cerebrum, cerebellum, brainstem, and spinal cord...

Dengue virus (DENV) causes immune-mediated diseases. Neurological involvement represents a severe condition that is rarely observed in DENV-1 infection. Neuromyelitis optica (NMO)/NMO spectrum disorders (NMOSD) are idiopathic immune-mediated demyelinating syndromes of the central nervous system. We report a 17-year-old female with oligosymptomatic DENV-1 viremia, diagnosed as NMOSD. Magnetic resonance imaging showed spinal cord and brainstem lesions. Antibody for aquaporin 4 was negative. DENV-1 RNA infection was detected by serial RT-PCR and confirmed by phylogenetic analysis in serum...

  Central nervous system (CNS), which is made up of brain and spinal cord, is protected from the invasion of harmful agents, such as various pathogens, chemical products or immune cells by a special structure "Blood Brain Barrier (BBB)". BBB highly preserves the homeostasis of CNS environment. On the other hand, there are many diseases in CNS regions which is associated with infection or autoimmunity, that means there may exist the "gateway" for pathogens or immune cells to attack CNS. Until recently, the molecular mechanism of the gateway formation has not been elucidated...

INTRODUCTION: Endoscopic discectomy and fusions have been gaining popularity in the recent past and are noted to be safe for its application in elderly population. It involves ultra-small incision for discectomy followed by placement of percutaneous screws in awake patients. Treatment of advanced spinal pathology using endoscope-assisted techniques are challenging. Although not common with endoscopic approach, post-operative infection can be problematic as there are no established guidelines on its management...

H-type bovine spongiform encephalopathy (H-BSE) is an atypical form of BSE in cattle. During passaging of H-BSE in transgenic bovinized (TgBoPrP) mice, a novel phenotype of BSE, termed BSE-SW emerged and was characterized by a short incubation time and host weight loss. To investigate the biological and biochemical properties of the BSE-SW prion, a transmission study was conducted in cattle, which were inoculated intracerebrally with brain homogenate from BSE-SW-infected TgBoPrP mice. The disease incubation period was approximately 15 months...

BACKGROUND: Lumbar microdiscectomy is the most commonly performed spinal surgery procedure, with over 300,000 cases performed annually in the United States alone. Traditionally, patients were advised to restrict post-operative activity as this was believed to reduce the risk of disc reherniation and progressive instability. However, this practice would often delay patients return to work. In contemporary practice many surgeons do not restrict patient post-operative activity due to the perception this practice is unnecessary...

History 50 year-old man with fever and headache starting one week after returning from his vacation in Thailand. His general practitioner prescribed amoxicillin/clavulanic acid, without further analyses to pinpoint the infection. Examinations The examination of cerebro-spinal fluid was crucial for the final diagnosis. Lumbar puncture demonstrated a predominantly mononuclear pleocytosis of 80 cells/µl (< 5) with an elevated protein of 782 mg/l (< 450); glucose and lactate were within normal limits...

BACKGROUND: The most common causes of pain following lumbar spinal fusions are residual herniation, or foraminal fibrosis and foraminal stenosis that is ignored, untreated, or undertreated. The original surgeon may advise his patient that nothing more can be done in his opinion that the nerve was visually decompressed by the original surgery. Post-operative imaging or electrophysiological assessment may be inadequate to explain all the reasons for residual or recurrent symptoms. Treatment of failed lumbar spinal fusions by repeat traditional open revision surgery usually incorporates more extensive decompression causing increased instability and back pain...

BACKGROUND: Postherpetic neuralgia (PHN) is a refractory condition that impairs the patient's quality of life (QoL), it develops secondary to herpes zoster infection. Therefore, it's important to prevent the transition of acute/subacute zoster-related pain to PHN. Despite of numerous studies, the optimal intervention that reduces PHN incidence is still unknown. OBJECTIVE: We evaluate the efficacy of short-term spinal cord stimulation (stSCS) in patients with refractory acute/subacute zoster-related pain...

INTRODUCTION: Surgical site infection is a potential complication of spinal cord stimulator (SCS) implantation. Current understanding of the epidemiology, diagnosis, and treatment of these infections is based largely on small clinical studies, many of which are outdated. Evidence-based guidelines for management of SCS-related infections thus rely instead on expert opinion, case reports, and case series. In this study, we aim to provide a large scale retrospective study of infection management techniques specifically for SCS implantation...

We present the case of a 63-year-old man, admitted for hand cellulitis and acute kidney injury. A Streptococcus dysgalactiae subsp equisimilis (SDSE) was isolated in blood cultures and despite directed intravenous antibiotherapy, the patient evolved unfavourably, with dorsolumbar spondylodiscitis, multifocal septic arthritis and abscesses. CT also showed densification of the gluteal muscles, multiple air bubbles in the psoas, paraspinal muscles and spinal canal that were associated with an intramuscular injection administered 1 week earlier for a backache...

BACKGROUND: Currently, many scholars are concerned about the treatment of postoperative infection; however, few have completed multivariate analyses to determine factors that contribute to the risk of infection. Therefore, we conducted a multivariate analysis of a retrospectively collected database to analyze the risk factors for acute surgical site infection following lumbar surgery, including fracture fixation, lumbar fusion, and minimally invasive lumbar surgery. METHODS: We retrospectively reviewed data from patients who underwent lumbar surgery between 2014 and 2016, including lumbar fusion, internal fracture fixation, and minimally invasive surgery in our hospital's spinal surgery unit...

BACKGROUND: Pedicle screw fixation in high grade lumbar listhetic vertebral body has been nightmare for Orthopaedic and spine surgeons. This is because of abnormally positioned listhetic pedicles and non-visualization of pedicle in conventional image intensifier (C-Arm). This results into increased surgical time, more blood loss, radiation exposure and more chances of infection. To overcome this problem, we have devised a new Technique of putting of pedicle screw fixation in listhetic vertebrae...

AIM: The mechanisms underlying detection and transmission of sensory signals arising from visceral organs, such as the urethra, are poorly understood. Recently, specialized ACh-expressing cells embedded in the urethral epithelium have been proposed as chemosensory sentinels for detection of bacterial infection. Here we examined the morphology and potential role in sensory signaling of a different class of specialized cells that express serotonin (5-HT), termed paraneurons. METHODS: Urethrae, dorsal root ganglia neurons and spinal cords were isolated from adult female mice and used for immunohistochemistry and calcium imaging...

The efficacy of spinal injection for chronic spinal pain is dubious for most conditions. They are however frequently prescribed. Side effects are poorly reported in the literature. In addition to benign and transient problems, serious and lethal side effects have been reported due to infection, hematoma or central and spinal cord infarctions which could be related to intravascular injection of corticoids. Although their frequency is excessively low, they should be discussed with every patient before prescription and should be mentioned in the consent form...

Autogenous bone graft is the best for spinal fusion in clinics, however, lacking sources, bleeding and infection are limited its practice. Seeking alternative materials are urgent for orthopaedic surgeon. Here, we evaluated osteoblast-oriented differentiation of rabbit BMSCs by co-culturing with composite scaffolds constructed using silicon-substituted-CaP-fine particulate bone powder-alginate. Using CCk8-kit, biocompatibility was evaluated by testing BMSCs proliferation; morphology and survival of osteoblasts within scaffolds were observed using EM and HE staining; growth factors and related genes were detected using RT-PCR...

A spinal epidural abscess is the collection of pus in the epidural space, and is a potentially life-threatening condition that requires early detection and prompt management. Almost two-thirds of cases are caused by Staphylococcus aureus, followed by Gram-negative bacilli which account for approximately 16% of cases. Raoultella planticola is an emerging pathogen, and is an extremely rare cause of invasive infection in humans. It has been reported to cause urinary tract infections, pneumonia, bacteraemia, cholangitis, cholecystitis, conjunctivitis and soft tissue infections...
