We evaluated the effects of intravenous dexmedetomidine during spinal anesthesia on hemodynamics, respiratory rate, oxygen saturation, sedpain, and compared them with those of saline infusion. Sixty American Society of Anesthesiologists physical status I and II cases were randomly divided into two groups. Patients were connected to the monitor after premedication, and spinal anesthesia was administered. Sensory and motor blockades were assessed using pinprick test and Bromage scale, respectively. Group I received dexmedetomidine infusion and Group II received saline infusion...

Damage to respiratory neural circuitry and consequent loss of diaphragm function is a major cause of morbidity and mortality in individuals suffering from traumatic cervical spinal cord injury (SCI). Repair of CNS axons after SCI remains a therapeutic challenge, despite current efforts. SCI disrupts inspiratory signals originating in the rostral ventral respiratory group (rVRG) of the medulla from their phrenic motor neuron (PhMN) targets, resulting in loss of diaphragm function. Using a rat model of cervical hemisection SCI, we aimed to restore rVRG-PhMN-diaphragm circuitry by stimulating regeneration of injured rVRG axons via targeted induction of Rheb (ras homolog enriched in brain), a signaling molecule that regulates neuronal-intrinsic axon growth potential...

Glycine is a fast inhibitory transmitter like γ-aminobutyric acid in the mammalian spinal cord and brainstem, and it is involved in motor reflex, nociception, and neuronal development. Triphenyltin (TPT) is an organometallic compound causing environmental hazard to many wild creatures. Our previous findings show that TPT ultimately induces a drain and/or exhaustion of glutamate in excitatory presynaptic nerve terminals, resulted in blockage of neurotransmission as well as methylmercury. Therefore, we have investigated the neurotoxic mechanism how TPT modulates inhibitory glycinergic transmission in the synaptic bouton preparation of rat isolated spinal neurons using a patch clamp technique...

BACKGROUND: Ehler-Danlos syndome (EDS) refers to a group of heritable connective tissue disorders; rare manifestations of which are cervical kyphosis and clinical myelopathy. Surgical treatment is described for the deformity in the thoracolumbar spine in adolescents but not for infantile cervical spine. Internal fixation for deformity correction in the infantile cervical spine is challenging due to the diminutive size of the bony anatomy and the lack of spinal instrumentation specifically designed for young children...

BACKGROUND: Multiple myeloma is characterised by monoclonal paraprotein production and osteolytic lesions, commonly leading to skeletal-related events (spinal cord compression, pathological fracture, or surgery or radiotherapy to affected bone). Denosumab, a monoclonal antibody targeting RANKL, reduces skeletal-related events associated with bone lesions or metastases in patients with advanced solid tumours. This study aimed to assess the efficacy and safety of denosumab compared with zoledronic acid for the prevention of skeletal-related events in patients with newly diagnosed multiple myeloma...

Highly Active Antiretroviral Therapy (HAART) has significantly contributed to the increase of HIV-infected survivors over 50 years of age. Unfortunately, patients are required to stay on long-term HAART, which may be causally related to the development of neurological problems such as chronic pain. Little is known about the contribution of HAART or its therapeutic agents to the pathogenesis of pain during aging. In this study, we determined the effect of nucleoside reverse transcriptase inhibitors (NRTIs) on the development of mechanical allodynia and the potential underlying mechanism in aging mice (15...

Intravenous human immunoglobulin G (IVIG) may have therapeutic benefit in neuromyelitis optica spectrum disorders (herein called NMO), in part because of the anti-inflammatory properties of the IgG Fc region. Here, we evaluated recombinant Fc hexamers consisting of the IgM μ-tailpiece fused with the Fc region of human IgG1. In vitro, the Fc hexamers prevented cytotoxicity in aquaporin-4 (AQP4) expressing cells and in rat spinal cord slice cultures exposed to NMO anti-AQP4 autoantibody (AQP4-IgG) and complement, with >500-fold greater potency than IVIG or monomeric Fc fragments...

REVIEW
David Oliveira Dias, Christian Göritz
Following lesions to the central nervous system, scar tissue forms at the lesion site. Injury often severs axons and scar tissue is thought to block axonal regeneration, resulting in permanent functional deficits. While scar-forming astrocytes have been extensively studied, much less attention has been given to the fibrotic, non-glial component of the scar. We here review recent progress in understanding fibrotic scar formation following different lesions to the brain and spinal cord. We specifically highlight recent evidence for pericyte-derived fibrotic scar tissue formation, discussing the origin, recruitment, function and therapeutic relevance of fibrotic scarring...

AIMS: We examined the efficacy of tramadol on the urethral reflex during sneezing, as well as the role of µ-opioid receptors in the spinal cord, in rats. METHODS: Forty-one female Sprague-Dawley rats were used. The rats were divided into normal female rats and rats with vaginal distension (VD), which mimics stress urinary incontinence (SUI) in humans. Under urethane anesthesia, the sneeze-induced amplitude of urethral responses (AUR) and baseline pressure (BP) were examined after intravenous injection of tramadol using a microtransducer-tipped catheter in both rat groups...

REVIEW
Zhihui Zhu, Georg Reiser
Small heat shock proteins (sHsps) are a group of proteins with molecular mass between 12 and 43 kDa. Currently, 11 members of this family have been classified, namely HspB1 to HspB11. HspB1, HspB2, HspB5, HspB6, HspB7, and HspB8, which are expressed in brain have been observed to be related to the pathology of neurodegenerative diseases, including Parkinson's, Alzheimer's, Alexander's disease, multiple sclerosis, and human immunodeficiency virus-associated dementia. Specifically, sHsps interact with misfolding and damaging protein aggregates, like Glial fibrillary acidic protein in AxD, β-amyloid peptides aggregates in Alzheimer's disease, Superoxide dismutase 1 in Amyotrophic lateral sclerosis and cytosine-adenine-guanine/polyglutamine (CAG/PolyQ) in Huntington's disease, Spinocerebellar ataxia type 3, Spinal-bulbar muscular atrophy, to reduce the toxicity or increase the clearance of these protein aggregates...

The partial recovery that can occur after a stroke has been attributed to structural and functional plasticity that compensate for damage and lost functions. This plasticity is thought to be limited in part by the presence of growth inhibitors in the central nervous system. Blocking or reducing signals from inhibitors of axonal sprouting such as Nogo and chondroitin sulfate proteoglycans (CSPGs) increases post-stroke axonal sprouting and improves recovery. We previously identified the transcription factor SOX9 as a key up-regulator of CSPG production and demonstrated that conditional Sox9 ablation leads to increased axonal sprouting and improved recovery after spinal cord injury...

Pregabalin, widely used in the treatment of several pain disorders, is usually well tolerated. Uncommonly, the drug may induce cardiac side effects, rarely prolongation of the PR interval. The latter has never been described in patients with healthy heart or normal renal function. We characterize a unique case of a young man with extrapulmonary tuberculosis and no detectable or known cardiac or kidney diseases, treated with pregabalin to control the severe pain due to the involvement of the spinal cord by the tuberculosis, showing an atrioventricular (AV) block due to pregabalin administration...

BACKGROUND: The serotonergic system is known to be involved in control of post-anesthetic shivering. Our hypothesis was that prophylactic granisetrone (serotonin antagonist) might reduce incidence of post- spinal anesthesia shivering in cesarean section. METHODS: Parturient scheduled for elective Caesarean delivery under spinal anesthesia were allocated to receive 0.9% saline (Group I, n = 71), 1 mg granisetron (Group II, n = 69), or 0.7 mg granisetron (Group III, n = 72) before the spinal block...

Development chemotherapy-induced peripheral neuropathic pain (CINP) compromises the use of chemotherapy and greatly impacts thousands of lives. Unfortunately, there are no FDA-approved drugs to prevent or treat CINP. Neuropathological changes within CNS, including neuroinflammation and increased neuronal excitability, are driven by alterations in neuro-glia communications; but the molecular signaling pathways remain largely unexplored. Adenosine is a potent neuroprotective purine nucleoside released to counteract the consequences of these neuropathological changes...
