Patients with cauda equina syndrome (CES) require emergency imaging and surgical decompression. The severity and type of symptoms may influence the timing of imaging and surgery, and help predict the patient’s prognosis. Categories of CES attempt to group patients for management and prognostication purposes. We aimed in this study to assess the inter-rater reliability of dividing patients with CES into categories to assess whether they can be reliably applied in clinical practice and in research. A literature review was undertaken to identify published descriptions of categories of CES. A total of 100 real anonymized clinical vignettes of patients diagnosed with CES from the Understanding Cauda Equina Syndrome (UCES) study were reviewed by consultant spinal surgeons, neurosurgical registrars, and medical students. All were provided with published category definitions and asked to decide whether each patient had ‘suspected CES’; ‘early CES’; ‘incomplete CES’; or ‘CES with urinary retention’. Inter-rater agreement was assessed for all categories, for all raters, and for each group of raters using Fleiss’s kappa.Aims
Methods
The aim of this study was to determine whether the sequential
application of povidone iodine-alcohol (PVI) followed by chlorhexidine
gluconate-alcohol (CHG) would reduce surgical wound contamination
to a greater extent than PVI applied twice in patients undergoing
spinal surgery. A single-centre, interventional, two arm, parallel group randomised
controlled trial was undertaken, involving 407 patients who underwent
elective spinal surgery. For 203 patients, the skin was disinfected before surgery using
PVI (10% [w/w (1% w/w available iodine)] in 95% industrial denatured
alcohol, povidone iodine; Videne Alcoholic Tincture) twice, and
for 204 patients using PVI once followed by CHG (2% [w/v] chlorhexidine
gluconate in 70% [v/v] isopropyl alcohol; Chloraprep with tint).
The primary outcome measure was contamination of the wound determined
by aerobic and anaerobic bacterial growth from samples taken after
disinfection.Aims
Patients and Methods
To determine factors such as age, sex and curve severity in patients with idiopathic scoliosis presenting for the first time to a spine deformity clinic. A prospective study at a regional spine clinic. Patients with idiopathic scoliosis presenting for the first time to the scoliosis clinic were entered into a database recording information such as age, symptoms, severity of scoliosis as measured by the Cobb angle (CA), spine rotation measured by Scoliometer, geographical region, person detecting the curve, neurological findings etc. The study period was from June 2008 to September 2009 inclusive. Fifty consecutive patients with all required information in the database were included in the analysis. All eligible patients were not entered due to logistical reasons. 13 males and 37 females, average age 13.96 (range 1 to 23). 68% were unhappy with the shape of their back, 48% presented with significant pain and 32% had both. The mother first saw the scoliosis in 52%, the rest were seen by either the patient, friends or doctors. 36 were single curves with a mean CA of 34 degrees ranging from 10 to 80 degrees. 52% of patients presented with a curve of 40 degrees or more. 14 had double curves. None of the patients were found to have any abnormal neurological findings. There are few epidemiological studies in the recent literature. This data was not previously available in our region and initial presentation with a severe curve is a worrying trend which triggered this study.
To analyse the pain distribution in the acute and chronic phase following thoracolumbar fractures. Prospective observational study 39 patients with fractures between T11 and L2, with no neurological deficit, were treated conservatively. Strict inclusion and exclusion criteria were applied. All had X-rays and MR imaging (whole spine) at post-injury and one-year follow-up. The patients documented their pain distribution using pain drawing, along with 10 other domains of pain and functional outcomes for a period over 12 months. The pain distribution was analysed. The association of distal pain distribution to - other associated injury, resultant kyphosis, Pre-existing or increase in disc degeneration at the lower non-injured disc levels – were analysed and reviewed The most common site of the pain distribution in both the acute (90%) and chronic phase (97%) was distal to the fracture (regions - iliac crest, lumbosacral junction and buttock). Factors mentioned above that could be related to distal pain distribution did not show any significant correlation (P>0.5) with different domains of pain outcome. Some of the commonly believed reasons for distal pain distribution like resultant kyphosis and associated disc/facet pathologies were not supported by our study findings. The distal pain distribution corresponds to the scelerotomal referred pain mapping, which could be the probable explanation. Thoracolumbar pathologies could be the source of pain in patients complaining of low back symptoms. Distal pain distribution of spine pathologies should not be attributed as functional.
