Development and delivery of the BOOST (Better Outcomes for Older adults with Spinal Trouble) intervention for older adults with neurogenic claudication

Neurogenic claudication due to spinal stenosis is a common cause of disability in older adults. Conservative treatments are a favourable treatment option. This paper describes the development and delivery of the BOOST (Better Outcomes for Older adults with Spinal Trouble) intervention, a physiotherapist-delivered physical and psychological intervention for the management of neurogenic claudication in older adults. The BOOST intervention is being tested in a multi-centre, randomised controlled trial in UK National Health Service Trusts; delivered by physiotherapists registered with the Health and Care Professionals Council. Participants are aged 65 years or older, registered with a primary care practice, and report symptoms consistent with neurogenic claudication. Intervention content and delivery was initially informed by clinical and patient experts, research evidence, and behaviour change guidelines; and refined following an intervention development day attended by researchers, health professionals, and Patient and Public Involvement representatives. The BOOST intervention comprises 12 group sessions, promoting sustained adherence with a long term home and physical activity programme. Each session includes education and group discussion, individually tailored exercises, and walking. Initial exercise levels are set at a one-to-one assessment. Continued home exercise adherence and increased physical activity following completion of the sessions is facilitated through support telephone calls.

Practical considerations in reducing swallowing dysfunction following concurrent chemoradiotherapy with intensity‐modulated radiotherapy for head and neck cancer

Data have emerged that the addition of concurrent chemotherapy to radiation can lead to swallowing dysfunction that may have an impact on patient quality of life and lead to significant morbidities such as poor nutritional status, enteral feeding tube dependence, and aspiration pneumonia. Although intensity‐modulated radiation therapy (IMRT) for head and neck cancer was initially developed to spare the parotid gland to reduce xerostomia, attention has recently focused on its utility to selectively decrease radiation dose to specified anatomic structures responsible for a functional swallow. Recent reports have proposed a variety of dose thresholds or constraints to these swallowing‐related structures, which may guide IMRT planning with the aim of reducing dysphagia. This critical review of the current literature assesses the feasibility of IMRT to maintain swallowing function and appraises the various dosimetric parameters that have been proposed to help minimize long‐term dysphagia. © 2013 Wiley Periodicals, Inc.

CMAP scan discontinuities: Automated detection and relation to motor unit loss

ObjectiveTo evaluate an automated method that extracts motor unit (MU) information from the CMAP scan, a high-detail stimulus–response curve recorded with surface EMG. Discontinuities in the CMAP scan are hypothesized to result from MU loss and reinnervation.MethodsWe introduce the parameter D50 to quantify CMAP scan discontinuities. D50 was compared with a previously developed manual score in 253 CMAP scans and with a simultaneously obtained motor unit number estimate (MUNE) in 173 CMAP scans. The effect of MU loss on D50 was determined with a simulation model.ResultsWe found a high agreement (sensitivity = 86.8%, specificity = 96.6%) between D50 and the manual score. D50 and MUNE were significantly correlated below 80 MUs (r = 0.65, n = 68, p < 0.001), but not when MUNE was larger than 120 MUs (r = 0.23, n = 59, p = 0.08).ConclusionsDiscontinuities in the CMAP scan as expressed by a decreased D50 are related to significant MU loss. The determination of D50 is objective, quantitative, and less time-consuming than both manual scoring and many existing MUNE methods.SignificanceD50 is potentially useful to monitor neurogenic disorders and moderate to severe MU loss.     

Anatomical details of neurogenic heterotopic ossification anterior to the ankylotic hip

Neurogenic heterotopic ossification (NHO) is a common complication in patients with spinal cord injury (SCI) and traumatic brain injury (TBI). Although there are many reports regarding the etiology, pathophysiology, and medical management, few studies elaborate the anatomical details of NHO, which leads to ankylosis of the hip joint. A prospective study on surgical resection of NHO in patients with hip ankylosis was conducted. Radiography and magnetic resonance imaging (MRI) were used to assess the relationship of the NHO block with the blood vessels, peripheral nerve, and surrounding muscles and bones. The anatomical relationships were also assessed and documented during the surgical procedures. NHO, which is anterior to the hip and causes hip ankylosis, settles into tissue planes without involving the tissue itself and does not disrupt the femoral neurovascular structures. The NHO bone block can then fuse to the cortex of adjacent bone. During resection, the normal bony contour should be exposed as a marker to guide the resection in order to avoid iatrogenic fracture.     

Rapid construction of sigmoid bladder augmentation using absorbable staples: Long-term results and comparison to standard colocystoplasty in children with neurogenic bladder

ObjectiveAbsorbable staples facilitate detubularization and reconfiguration of the bowel when performing augmentation colocystoplasty. We compared the outcomes of stapled sigmoid augmentation with standard sutured colocystoplasty.Materials and methodsBetween 2003 and 2011, 108 children underwent bladder augmentation at our institution. Colocystoplasty was used in 30 patients (27.8%). Medical charts of children who underwent stapled (n = 8) or sutured (n = 22) sigmoid augmentation were compared with regard to patient demographics and surgical complications, including anastomotic leak and urolithiasis.ResultsEight children with underwent stapled sigmoid colocystoplasty. Average age at surgery was 8 years (range 4–17 years). Time to detubularize and refashion the bowel segment prior to augmentation was consistently under 5 min. Average length of follow-up was 44 months (range 12–80 months). One patient experienced anastomotic leak. Two of eight children (25%) in the stapled anastomosis cohort developed bladder stones. Twenty-two patients underwent standard sigmoid augmentation during the same time period (average age 8.2 years; range 4–16 years). One of 22 (4.5%) experienced anastomotic leak. Seven of 22 (31.8%) developed cystolithiasis.ConclusionsComplications from stapled sigmoid anastomosis are similar to those from standard colocystoplasty. Use of absorbable staples decreases operating time by avoiding bowel spatulation and suturing, and should be considered in pediatric patients undergoing colocystoplasty.
