PURPOSE: Articaine is used as a local anesthetic for outpatient surgery because it offers rapid onset of anesthesia and short duration motor block. Levobupivacaine is often preferred for Caesarean section. We evaluated the anesthetic characteristics of fentanyl-supplemented plain articaine and levobupivacaine for Caesarean section under combine spinal epidural anesthesia. METHODS: Patients undergoing Caesarean section received in random order plain articaine 40 mg (Group A, n=50) or plain levobupivacaine 10 mg (Group L, n=50) mixed with fentanyl 20 µg intrathecally...

BACKGROUND CONTEXT: Compromise of pedicle screw purchase is a concern in maintaining rigid spinal fixation, especially with osteoporosis. Little consistency exists among various tapping techniques. Pedicle screws are often prepared with taps of a smaller diameter, which can further exacerbate inconsistency. PURPOSE: To determine whether a mismatch between tap thread depth (D) and pitch (P) and screw thread D and P affects fixation when under-tapping in osteoporotic bone...

The care of the older person with hip fracture is complicated by their comorbid condition, limited physiological reserve, cognitive impairment and frailty. Two aspects of hip fracture management that have received considerable attention are how best to manage the pain associated with it and the ideal mode of anaesthesia. Existing literature has reported on the suboptimal treatment of pain in this orthogeriatric cohort. With recent advancements in medical care, a number of options have emerged as alternatives to conservative systemic analgesia...

More than 90% of spinal cord injuries are caused by traumatic accidents and are often associated with other tissue damage (polytrauma) that can provide a source of continued pain input during recovery. In a clinically relevant spinal cord contusion injury model, prior work has shown that noxious stimulation at an intensity that engages pain (C) fibers soon after injury augments secondary injury and impairs functional recovery. Noxious input increases the expression of pro-inflammatory cytokines (interleukin 1β and 18), cellular signals associated with cell death (caspase 3 and 8), and physiological signs of hemorrhage...

We have recently reported that repeated systemic treatments of extract from Corydalis yanhusuo alleviate neuropathic pain and levo-tetrahydropalmatine (l-THP) is one of active components from Corydalis. We designed this study to investigate antinociceptive effect of l-THP in acute and chronic pain models and related mechanism within the spinal cord. We found that intraperitoneal pretreatment with l-THP significantly inhibited the second phase of formalin-induced pain behavior. In addition, intrathecal as well as intraperitoneal pretreatment with l-THP reduced the mechanical allodynia (MA) induced by direct activation of sigma-1 receptor (Sig-1)...

Equid herpes virus type-1 (EHV-1) is a major pathogen of horses, causing abortion storms and outbreaks of herpes virus myeloencephalopathy. These clinical syndromes are partly attributed to ischemic injury from thrombosis in placental and spinal vessels. The mechanism of thrombosis in affected horses is unknown. We have previously shown that EHV-1 activates platelets through virus-associated tissue factor-initiated thrombin generation. Activated platelets participate in thrombus formation by providing a surface to localize coagulation factor complexes that amplify and propagate thrombin generation...

BACKGROUND: The conventional technique for sacroiliac (SI) joint injection involves aligning the anterior and posterior aspects of the SI joint under fluoroscopic guidance and then entering the SI joint in the most caudal aspect. OBJECTIVE: We wish to highlight that there is no added advantage to aligning both the anterior and posterior joint lines of the SI joint as it is time consuming, associated with additional radiation exposure, and may make the entry into the posterior SI joint technically more difficult...

Here it is shown that paclitaxel induced neuropathy is associated with the development of spontaneous activity (SA) and hyperexcitability in DRG neurons that is paralleled by increased expression of low-voltage-activated calcium channels (T-type; Cav3.2). The percentage of DRG neurons showing SA and the overall mean rate of SA were significantly higher at day 7 of paclitaxel treatment than in rats receiving vehicle. Cav3.2 expression was increased in L4-6 DRG and spinal cord segments in paclitaxel-treated rats, localized to small calcitonin gene-related peptide expressing and isolectin B4 expressing DRG neurons and to glial fibrillary acidic protein-positive spinal cord cells...

The heat-sensitive transient receptor potential vanilloid 1 (TRPV1) channels are expressed in the peripheral and central nervous systems. However, there is no report on how the activation of TRPV1 causes the modulation of neuronal activity in the medullary respiratory center. We examined effects of capsaicin, a specific agonist of TRPV1 channels, on respiratory rhythm generation in brainstem-spinal cord preparation from newborn rats. Capsaicin induced a biphasic response in the respiratory rhythm (a transient decrease followed by an increase in the C4 rate)...

Cutaneous inflammation alters the function of primary afferents and gene expression in the affected dorsal root ganglia (DRGs). However specific mechanisms of injury-induced peripheral afferent sensitization and behavioral hypersensitivity during development are not fully understood. Recent studies in children suggest a potential role for growth hormone (GH) in pain modulation. GH modulates homeostasis and tissue repair after injury, but how GH effects nociception in neonates is not known. To determine if GH played a role in modulating sensory neuron function and hyper-responsiveness during skin inflammation in young mice, we examined behavioral hypersensitivity and the response properties of cutaneous afferents using an ex vivo hairy skin-saphenous nerve-dorsal root ganglion (DRG)-spinal cord preparation...

BACKGROUND: Low-dose spinal anaesthesia is a safe and reliable anaesthesia technique in outpatient perianal surgery. Regarding its short duration of action and its trend to hyperbaric characteristics, plain chloroprocaine 10 mg/ml seems to be ideal to perform low-dose spinal anaesthesia. The aim of this trial was to determine the optimal dosage of chloroprocaine for this indication. METHODS: Hundred and twenty patients undergoing perianal surgery were enrolled and randomly allocated to receive 10, 20 or 30 mg of chloroprocaine 10 mg/ml intrathecally...

Management of women with Complete Heart Block (CHB) presenting without pacing, during pregnancy and labour is debatable. Temporary pacemakers have been routinely inserted for labour and birth probably to withstand any haemodynamic variations. However, due to lack of large scale prospective studies, the necessity of this procedure has not been objectively assessed. Also, the most appropriate anaesthetic technique for caesarean section in women with CHB is yet to be clarified. We report herein the case of a pregnant woman with CHB who had uneventful emergency caesarean delivery under spinal anaesthesia without temporary pacing...

Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disease and one of the leading inherited causes of infant mortality. SMA results from insufficient levels of the survival motor neuron (SMN) protein, and studies in animal models of the disease have shown that increasing SMN protein levels ameliorates the disease phenotype. Our group previously identified and optimized a new series of small molecules, with good potency and toxicity profiles and reasonable pharmacokinetics, that were able to increase SMN protein levels in SMA patient-derived cells...

BACKGROUND: Spinal anesthesia (SA) in the lateral decubitus position is often used to perform total hip arthroplasty (THA). Hypobaric local anesthetic ensures enhanced and prolonged sensory and motor block in the involved side. The aim of this study was to compare the intraoperative anesthetic efficacy of hypobaric with isobaric levobupivacaine solutions for THA. METHODS: Forty patients scheduled to elective THA were allocated into two groups: isobaric levobupivacaine group (IL group) and hypobaric levobupivacaine group (HL group)...

Nerve injury-induced downregulation of voltage-gated potassium channel subunit Kcna2 in the dorsal root ganglion (DRG) is critical for DRG neuronal excitability and neuropathic pain genesis. However, how nerve injury causes this downregulation is still elusive. Euchromatic histone-lysine N-methyltransferase 2, also known as G9a, methylates histone H3 on lysine residue 9 to predominantly produce a dynamic histone dimethylation, resulting in condensed chromatin and gene transcriptional repression. We showed here that blocking nerve injury-induced increase in G9a rescued Kcna2 mRNA and protein expression in the axotomized DRG and attenuated the development of nerve injury-induced pain hypersensitivity...
