Outcomes of spinal cord injury following cervical fracture in ankylosing spondylitis and diffuse idiopathic skeletal hyperostosis (DISH): A prospective cohort study / Lesión medular cervical traumática en pacientes afectados de espondilitis anquilosante y DISH. Estudio comparativo prospectivo

Introduction The ankylosed spine is prone to increased fractures risk even after minor trauma. The lower cervical spine is most frequently injured, and fractures of the ankylosed spine tend to precipitate spinal cord injury (SCI). The objective of the current study is to assess the incidence, management, and outcomes of patients with ankylosis of the spine sustaining a cervical fracture with associated SCI over a 7-year period. Material and methods Prospective cohort study. Patients referred to the institution with a cervical fracture associated with SCI on a background of AS or DISH from 2009 to 2017 were reviewed. Demographics, mechanism of injury, fracture type, neurological level of injury, time to surgery, surgical management, neurological status (AIS), spinal cord independence measure (SCIMIII) scale at admission and discharge, and hospital length of stay. In September 2019 the summative data was analyzed using NDI, VAS, SV-QLI/SCI and length of survival were analyzed for statistical significance. Pathological fractures and dementia were excluded. Results 1613 patients with traumatic SCI were admitted in this period of whom 37 (12 AS and 25 DISH) met the inclusion criteria (mean age 65 years AS; 67 DISH). Fracture-dislocation was the most frequent fracture type (33% AS patients, 24% DISH patients). C4 was the most common neurological level of injury. SCIMIII score at admission was 1 point and 59 at discharge. AIS at admission was A (50%). At time of discharge no patient had neurologically deteriorated. Post-discharge mortality was 58% in AS patients and 32% in DISH patients (p=0.13).ConclusionsBoth AS and DISH patients have high levels of disability and mortality associated with trauma to the cervical spine...

Reducing Surgical Site Infection in Pediatric Scoliosis Surgery: A Multidisciplinary Improvement Program and Prospective 4-Year Audit.

STUDY DESIGN: Single-center prospective cohort. OBJECTIVES: To evaluate a multidisciplinary led, structured protocol for reducing surgical site infections (SSIs) in pediatric scoliosis surgery. METHODS: Following a spike to 8.6% in local annual infection rate, a multidisciplinary team was convened to identify interventions. The team consisted of spinal surgeons, infectious diseases consultants, physiotherapists, specialist nurses, and theatre managers. A protocol was initiated, including preoperative skin decontamination; standardized operative site prepreparation; betadine-soaked swabs sutured to wound edges; blood loss minimization; 3 L0.9% saline pulsed-lavage; defined protocol of glove changes; antibiotic regime of preoperative gentamicin, intraoperative subfascial vancomycin powder, 48-hour cefuroxime; and intraoperative normothermia. A 4-year audit was initiated of all patients aged ≤18 years undergoing corrective spinal deformity surgery. Institutional board review was not required. RESULTS: Between January 1, 2014 and January 1, 2018, 414 operations were performed on 355 patients: male:female = 1:2.2, mean age 13.7 years (range 2.5-17.9), 233 idiopathic (mean operated vertebral levels 12), 122 neuromuscular (mean operated vertebral levels 14), 66 growing rod procedures, 41 multistage procedures. The mean number of operated vertebral levels both overall and in infected cases was 13 (range 2-17). Nine SSIs occurred in 8 patients at 3 months (4 neuromuscular), resulting in an overall SSI per operation of 2.2%. CONCLUSION: A multidisciplinary approach with standardized measures significantly reduced SSIs in the unit's pediatric scoliosis surgery.

The local thermal effect of using monopolar electrosurgery in the presence of a deep brain stimulator: Cadaveric studies on a lamb brain.

In 2001, a patient with a deep brain stimulator (DBS) died following treatment with medical diathermy. Manufacturers have since advised against all forms of diathermy except bipolar electrosurgery in DBS patients. This effective ban on monopolar electrosurgery has an impact on the 150,000 patients treated with DBS to date, a number that is set to progressively increase. Analysis of the events, technical specifications, and literature suggests that the original ban was based on extrapolation from medical diathermy to electrosurgery, two very different treatment modalities. This prompted novel work exploring the impact of electrosurgery on DBS systems. Monopolar electrosurgery was employed on an animal cadaveric model with a DBS system paired with a thermocouple at the brain implant site. Prolonged use of monopolar, including at settings higher than normal surgical practice, resulted in a maximum mean temperature increase of only 2.6 °C. Microscopic post-event analysis showed no evidence of thermal injury at the implant site. The implication is that there may be limits within which monopolar electrosurgery use is safe in patients with DBS.

Invasive sinonasal adenocarcinoma with an absent olfactory bulb: a case report.

Sinonasal adenocarcinomas are rare, locally invasive tumours. In this case the symptomatic profile was unusual and the diagnosis was missed at the primary care stage. Interestingly this would be the first documented case with an absent ipsilateral olfactory bulb. A 55-year old male presented with symptoms of behavioural change and mild headaches. He was later found to have a large Sinonasal adenocarcinoma which penetrated the skull base. This was treated by a combined craniotomy and endonasal approach. Sinonasal adenocarcinomas are unusual tumours and further research is required in order to clarify management strategies and prognosis. This interesting case was more unusual again given its presentation, extent and absence of the olfactory bulb. Importantly for primary care physicians the initial diagnosis was considered psychiatric rather than organic; despite there being specific features of the presentation which were suggestive of an intra-cranial lesion.

Cranioplasty outcomes and associated complications: A single-centre observational study.

INTRODUCTION: The resurgence of decompressive craniectomy has led to recent published reviews of the safety of cranioplasties. To date there is a wide range of reported mortality and morbidity. This observational study reports the outcomes of the cranioplasty operations from a single centre and evaluates the factors involved in their management. METHODS: A retrospective search of all theatre logs was performed for the years 2006-2013 inclusive. 88 operations were documented as 'Cranioplasty'. Data collection include patient demographics, type of cranioplasty used, time lapse between decompression and cranioplasty, seniority of the operating surgeon(s), antibiotic regimen and complications. Outcomes were recorded at the three-month follow-up. RESULTS: The overall complication rate was 6.8%. The mean patient age was 36.2 years. 52.2% of patients had decompressive craniectomy for trauma, 11.3% had infectious pathology, 9% had subarachnoid haemorrhage, 9% had tumour with bone infiltration and 3.4% had stroke. 55.7% of patients had cranioplasty within 6 months of craniectomy. 61.3% of cranioplasties were with autologous bone, 20.4% titanium, 10.2% acrylic and 7.9% polyetheretherketone (PEEK). Significant complications included one case of infection, two cases of subgaleal haematoma and one extradural collection. No deaths were noted. No correlation was found between infection and the use of drains. 68.6% of cases were done by either a senior surgeon or a supervised registrar. There was an observable difference in complication rates in relation to the seniority and experience of the operator. However, patient numbers and complications were insufficient to achieve statistical significance. Strict antimicrobial prescribing was observed. CONCLUSION: Some potentially preventable complications have been addressed with a resulting rate of complications lower than other published reports. We use two standard adjuncts: the presence of a senior surgeon and strict antimicrobial regimens. We believe that our results could be transferrable to other units by following similar guidelines.

Intracranial abscess in Ectopia Cordis.

We present a case of intracranial abscess in a young female with Ectopia Cordis, an exceptionally rare cardiac condition. The neurosurgical implication is the predisposition to intracranial abscess formation. A heightened awareness of this association will aid diagnosis in similar clinical scenarios.

Neurosarcoidosis mimicking acute cervical disc prolapse.

We describe the case of a 29-year-old farmer who developed upper limb radiculopathy followed by myelopathy in his lower limbs. MRI findings suggested cervical disc prolapse with cord changes. Despite a successful anterior cervical decompression and fusion his symptoms rapidly returned. Further investigations ultimately diagnosed underlying neurosarcoidosis.
