BACKGROUND: Spondylodiscitis are vertebral column infections whose incidence is rising due to an increase of the susceptible population and improved ascertainment. They have been associated with a wide range of microorganisms. Fungal spondylodiscitis is uncommon (0.5%-1.6%) and strongly associated with immunodepression and diabetes (Gouliouris et al., 2010). We present a rare case of Candida glabrata spondylodiscitis in a non neutropenic diabetic patient with the review of the literature...

Primary leptomeningeal primitive neuroectodermal tumors (PNETs) are extremely rare childhood central nervous system malignancies harboring a very poor prognosis. There is no consensus treatment for these tumors to date. We report a case of a 10-year-old male who presented with mental status change, hydrocephalus, intracranial and spinal diffuse leptomeningeal enhancement without a primary mass upon cranial imaging and a negative initial biopsy until five months into his presentation. He responded significantly well to initial chemotherapy and radiotherapy...

BACKGROUND: Thymic carcinoid with spinal metastasis is an extremely rare entity. Clinically, the tumor presents either by its endocrine manifestations or by mechanical compression of surrounding structures. However, no previous studies reported a case with neck pain, and neurological deficit as initial presentation of an atypical thymic carcinoid. METHOD: A 56-year-old non-smoking man presented with 12-month history of intermittent neck pain and 1-month history of progressive numbness and weakness of the right upper limb...

Joho Yun, Jinhwan Kim, Jong-Hyun Lee
We have introduced a fabrication method for electrical impedance spectroscopy (EIS)-on-a-needle (EoN: EIS-on-a-needle) to locate target tissues in the body by measuring and analyzing differences in the electrical impedance between dissimilar biotissues. This paper describes the fabrication method of fine interdigitated electrodes (IDEs) at the tip of a hypodermic needle using a photoresist spray coating and flexible film photomask in the photolithography process. A polyethylene terephthalate (PET) heat shrink tube (HST) with a wall thickness of 25 µm is employed as the insulation and passivation layer...

We transplanted human olfactory bulb OECs (hOECs) mixed with collagen into a unilateral transection of four dorsal roots (C6-T1) in a rat model. By mixing with collagen, we could maximise the limited numbers of hOEC from an olfactory bulb biopsy and optimise cavity-filling. Cyclosporine was administered daily to prevent immune rejection. Forelimb proprioception was assessed weekly in a vertical climb task. Half of the rats receiving hOEC transplants showed some functional improvement ('responders') over six weeks of the study whilst the other half did not ('non-responders') and performed similarly to 'injured only' rats...

Nocardiosis of the central nervous system and spine, in particular, is a rare infection with significant morbidity and mortality. Treatment is usually with antibiotics and surgical drainage or biopsy. The authors report a case of a 49-year-old man who presented with chronic lower back pain and paraplegia. He was found to have spinal subdural empyema caused by Nocardia farcinica. Laminectomy and sampling of the subdural collection were performed, and the patient was treated with triple intravenous antibiotics (linezolid, amikacin and ciprofloxacin)...

BACKGROUND: Oculoleptomeningeal amyloidosis (OLMA) represents a rare subtype of familial transthyretin (TTR) amyloidosis, characterized by deposition of amyloid in cranial and spinal leptomeninges along with ocular involvement. Of more than 100 TTR mutations identified, few have been associated with OLMA. Herein we describe the first report of leptomeningeal amyloidosis associated with the c.381T>G (p.Ile127Met) TTR mutation, linking this variant in the OLMA phenotype. CASE DESCRIPTION: A 53 year-old male presented with a 2-year history of progressive symptoms including upper and lower limb weakness, ataxia, peripheral and autonomic neuropathy...

INTRODUCTION: The most common form of spinal muscular atrophy (SMA) is a recessive disorder caused by SMN1 mutations in 5q13, whereas the genetic etiologies of non-5q SMA are very heterogenous and largely remain to be elucidated. We present a father and son with atrophy and weakness of the lower leg muscles since infancy. Genetic studies in this family revealed a novel BICD2 mutation causing autosomal dominant lower extremity-predominant SMA type 2. PATIENTS: The proband was the father, aged 30, and the son was aged 3...

RATIONALE: Intraneural perineurioma is an extremely rare form of peripheral nerve sheath tumor; and the anesthetic management of a parturient with intraneural perineurioma, especially affecting spinal roots and nerves of extremities, is very rare. PATIENT CONCERNS: A 28-year-old woman was referred to the hospital at 37+5 weeks' gestation, presenting with a 10-year history of paroxysmal acroanesthesia and aching with distal limbs. DIAGNOSES: Based on the biopsy results, including immunohistochemical and electron microscopic findings, and molecular studies, her condition was diagnosed as intraneural perineurioma...

RATIONALE: Sensory neuronopathy can be a devastating peripheral nervous system disorder. Profound loss in joint position is associated with sensory ataxia, and reflects degeneration of large-sized dorsal root ganglia. Prompt recognition of sensory neuronopathies may constitute a therapeutic window to intervene before there are irreversible deficits. However, nerve-conduction studies may be unrevealing early in the disease course. In such cases, the appearance of dorsal column lesions on spinal-cord MRI can help in the diagnosis...

Notalgia paresthetica (NP) is an underdiagnosed condition that presents with unilateral pruritus medial to the scapula on the midback with or without an associated hyperpigmented or hypopigmented macule. There is a paucity of recent reviews on this chronic cutaneous neuropathy in peer-reviewed journals. Current theories propose the condition is likely multifactorial, including spinal entrapment and muscular compressive neuropathy. An extensive literature review was performed by searching the MEDLINE database to review all published works on notalgia paresthetica...

Tuberculous spondylodiscitis usually affects the dorso-lumbar spine, and its cervical location is a rare condition that can mimic other diseases and consequently cause treatment delays. We report a case of tuberculous spondylodiscitis of the lower cervical spine discovered under unusual circumstances in a patient with severe polytrauma involving a cranio-cerebral trauma, a non-displaced fracture of the two laminæ and the spinous process of the C6 vertebrae as well as fibular and tibial shaft fractures. The patient underwent static tibial nailing, and a collar with occipital and chin supports was applied...

Case summary: A 12-year-old domestic shorthair cat was presented with acute non-painful hindlimb proprioceptive ataxia localising to T3-L3 spinal cord segments. MRI revealed paravertebral muscular hyperintensity on T2-weighted images at the level of T7-T8 vertebrae. The cat improved on conservative management but deteriorated 3 months later. Repeated MRI showed meningeal enhancement at the same level and hyperintensity of the paravertebral musculature extending to the right thoracic wall and pleural space on short tau inversion recovery images...
