BACKGROUND: Children that have had a meningomyelocele repair often present for hip and bilateral lower limb surgeries. Due to vertebral, epidural, and nerve root abnormalities, placement of epidural catheter is difficult. AIMS: We aim to describe the potential role of ultrasound in delineating the most appropriate intervertebral space for central neuroaxial blocks in these patients. METHOD: Twelve children with previous meningomyelocele repair, in the age group of 6-12 years posted for hip or bilateral lower limb surgeries were included...

Background: Lumbar puncture is a well-known procedure. The indications for lumbar puncture vary among different medical and surgical disciplines, though obtaining a sample for cerebrospinal fluid analysis is the most common one. A normal coagulation profile is crucial prior to pursing the procedure. Occasionally, an urgent sample is needed to guide an appropriate treatment while the patient's coagulation status is suboptimum. In those specific critical situations, some may accept suboptimal correction owing to the urgency of the case...

INTRODUCTION: Recent animal studies demonstrated immunosuppressive effects of opioid withdrawal resulting in a higher risk of infection. The aim of this study was to determine the impact of remifentanil discontinuation on Post-Anesthesia Care Unit (PACU)-acquired infection after a schedule of sedoanalgesia of at least 6 days. METHOD: All patients over 18 years of age with a unit admission of more than 4 days were consecutively selected. The study population was the one affected by surgical pathology of any origin where sedation was based on any hypnotic and the opioid remifentanil was used as analgesic for at least 96 hours in continuous perfusion...

Traumatic spinal cord injury (SCI) is a detrimental condition that causes loss of sensory and motor function in an individual. Many complex secondary injury cascades occur after SCI and they offer great potential for therapeutic targeting. In this study, we investigated the response of endogenous neural progenitor cells, astrocytes, and microglia to a localized thoracic SCI throughout the neuroaxis. Twenty-five adult female Sprague-Dawley rats underwent mild-contusion thoracic SCI (n = 9), sham surgery (n = 8), or no surgery (n = 8)...

OBJECTIVE Myxopapillary ependymoma is a benign WHO Grade I tumor most commonly located in the conus-cauda equina region of the spine. Although this tumor is defined by an overall excellent survival, dissemination throughout the whole neuraxis occurs frequently. The current study evaluated the clinical characteristics and significance of myxopapillary ependymoma metastases. METHODS Patients who underwent surgery from 2005 to 2015 for treatment of spinal myxopapillary ependymoma were included in the study. Charts were reviewed for primary tumor symptoms and initial treatment, local recurrence, response to salvage therapy, and presence and behavior of distant metastases...

Ependymomas are childhood brain tumors that occur throughout the central nervous system, but are most common in the hindbrain, also known as the posterior fossa (PF). Current standard therapy comprises maximal safe surgery, and there is no scope for further increase in survival. Despite the histological similarity, ependymomas from throughout the neuroaxis likely comprise multiple independent entities, each with a distinct molecular pathogenesis. The present review article would discuss both genetics and epigenetics of ependymomas...

BACKGROUND: Despite recent advances in surgery and anaesthesia which significantly improve safety, many health facilities in low-and middle-income countries (LMICs) remain chronically under-resourced with inability to cope effectively with serious obstetric complications (Knight et al., PLoS One 8:e63846, 2013). As a result many of these countries still have unacceptably high maternal and neonatal mortality rates. Recent data at the national referral hospitals in East Africa reported that none of the national referral hospitals met the World Federation of Societies of Anesthesiologists (WFSA) international standards required to provide safe obstetric anaesthesia (Epiu I: Challenges of Anesthesia in Low-and Middle-Income Countries...

OBJECTIVE: We aimed to determine the potential of aberrant glial cells (AbAs) isolated from the spinal cord of adult SOD1G93A symptomatic rats to induce gliosis and neuronal damage following focal transplantation into the lumbar spinal cord of wild-type rats. METHODS: AbAs were obtained from the spinal cords of SOD1G93A symptomatic rats. One hundred thousand cells were injected using a glass micropipette into the lumbar spinal cords (L3-L5) of syngeneic wild-type adult rats...

REVIEW
Donald W Pfaff, Michael J Baum
Testosterone (T) can act directly through neural androgen receptors (AR) to facilitate male sexual behavior; however, T's metabolites also can play complicated and interesting roles in the control of mating. One metabolite, dihydrotestosterone (DHT) binds to AR with significantly greater affinity than that of T. Is that important behaviorally? Another metabolite, estradiol (E), offers a potential alternative route of facilitating male mating behavior by acting through estradiol receptors (ER). In this review we explore the roles and relative importance of T as well as E and DHT at various levels of the neuroaxis for the activation of male sex behavior in common laboratory animals and, when relevant research findings are available, in man...

Anterior iliac crest bone grafting is a well-established modality in the treatment of alveolar bone deficiencies. However, this procedure may also have considerable postoperative morbidity which is mostly related to general anesthesia. Postoperative pain-related complications can be managed by neuroaxial blockade techniques which provide adequate surgical analgesia and reduce postoperative pain. This clinical report describes the reconstruction of a severely atrophic maxilla with anterior iliac crest bone grafting using combined spinal epidural anesthesia...

BACKGROUND: Chordomas arise from remnants of the notochord and occur throughout the neuroaxis. En bloc resection of chordomas can prove especially challenging in the upper cervical spine secondary to the unique structural anatomy and intimate relationship to the vertebral arteries and spinal cord. CASE DESCRIPTION: We describe the resection of a C2-C3 chordoma in a 55-year-old woman in 2-stage fashion with preservation of the vertebral arteries. First, a posterior instrumented fusion and removal of the posterior elements was performed, followed by an anterior transmandibular en bloc resection with cage reconstruction with kick-plate support achievable with off-the-shelf products...

INTRODUCTION: Aortic stenosis is a valvular lesion that poses several haemodynamic challenges for the anaesthesiologist. The use of central regional anaesthesia is traditionally regarded as contraindicated in patients with severe aortic stenosis due to its sympatholytic effect, potentially causing loss of vascular tone and ultimately diminished cardiac output. The aim of this paper was to review current literature to find evidence for or against the use of neuroaxial blockade in patients with aortic stenosis...

The prion hypothesis has extended to the fatal motor neuron disease, amyotrophic lateral sclerosis (ALS), as a means to explain the spatiotemporal spread of pathology from one or more focal points through the neuroaxis. About 20% of inheritable cases of ALS are due to mutation in the gene encoding the Cu/Zn superoxide dismutase (SOD1), causing the protein to misfold and form neurotoxic aggregates. Mutant SOD1 has been shown to impart its misfold onto natively folded wild-type SOD1 in living cells. Furthermore, misfolded wild-type SOD1 can itself induce further rounds of propagated SOD1 misfolding...

Neurofibromatosis type 2 (NF2), a neurogenetic condition manifest by peripheral nerve sheath tumors (PNST) throughout the neuroaxis for which there are no approved therapies. In vitro and in vivo studies presented here examine agents targeting signaling pathways, angiogenesis, and DNA repair mechanisms. In vitro dose response assays demonstrated potent activity of lapatinib and nilotinib against the mouse schwannoma SC4 (Nf2 (-/-)) cell line. We then examined the efficacy of everolimus, nilotinib, lapatinib, bevacizumab and radiation (RT) as mono- and combination therapies in flank and sciatic nerve in vivo NF2-PNST models...

Anaphylaxis is a sudden-onset, severe hypersensitivity reaction that can be potentially fatal. It can often transition to refractory hemodynamic instability, eventually resulting in death. Stress-related cardiomyopathies (SRCs) have multifactorial etiologies, including being linked to excessive catecholamine release in periods of intense stress. This novel case report recounts a SRC caused by contrast-induced anaphylaxis within 1 hour post percutaneous coronary intervention. Both acutely life-threatening conditions may occur simultaneously and are implicated with devastating complications...
