RESUMO
BACKGROUND: Parkinson's disease (PD) affects approximately 145,519 people in the UK. Speech impairments are common with a reported prevalence of 68%, which increase physical and mental demands during conversation, reliance on family and/or carers, and the likelihood of social withdrawal reducing quality of life. In the UK, two approaches to Speech and Language Therapy (SLT) intervention are commonly available: National Health Service (NHS) SLT or Lee Silverman Voice Treatment (LSVT LOUD®). NHS SLT is tailored to the individuals' needs per local practice typically consisting of six to eight weekly sessions; LSVT LOUD® comprises 16 sessions of individual treatment with home-based practice over 4 weeks. The evidence-base for their effectiveness is inconclusive. METHODS/DESIGN: PD COMM is a phase III, multicentre, three-arm, unblinded, randomised controlled trial. Five hundred and forty-six people with idiopathic PD, reporting speech or voice problems will be enrolled. We will exclude those with a diagnosis of dementia, laryngeal pathology or those who have received SLT for speech problems in the previous 2 years. Following informed consent and completion of baseline assessments, participants will be randomised in a 1:1:1 ratio to no-intervention control, NHS SLT or LSVT LOUD® via a central computer-generated programme, using a minimisation procedure with a random element, to ensure allocation concealment. Participants randomised to the intervention groups will start treatment within 4 (NHS SLT) or 7 (LSVT LOUD®) weeks of randomisation. PRIMARY OUTCOME: Voice Handicap Index (VHI) total score at 3 months. Secondary outcomes include: VHI subscales, Parkinson's Disease Questionnaire-39; Questionnaire on Acquired Speech Disorders; EuroQol-5D-5 L; ICECAP-O; resource utilisation; adverse events and carer quality of life. Mixed-methods process and health economic evaluations will take place alongside the trial. Assessments will be completed before randomisation and at 3, 6 and 12 months after randomisation. The trial started in December 2015 and will run for 77 months. Recruitment will take place in approximately 42 sites around the UK. DISCUSSION: The trial will test the hypothesis that SLT is effective for the treatment of speech or voice problems in people with PD compared to no SLT. It will further test whether NHS SLT or LSVT LOUD® provide greater benefit and determine the cost-effectiveness of both interventions. TRIAL REGISTRATION: International Standard Randomised Controlled Trials Number (ISRCTN) Registry, ID: 12421382. Registered on 18 April 2016.

BACKGROUND CONTEXT: Cervical spondylotic myelopathy (CSM) is a chronic spinal cord disease and can lead to progressive or stepwise neurologic decline. Several factors may influence this process, including extent of spinal cord compression, duration of symptoms, and medical comorbidities. Diabetes is a systemic disease that can impact multiple organ systems, including the central and peripheral nervous systems. There has been little information regarding the effect of diabetes on patients with coexistent CSM. PURPOSE: To provide empirical data regarding the effect of diabetes on treatment outcomes in patients who underwent surgical decompression for coexistent CSM. STUDY DESIGN/SETTING: Large prospective multicenter cohort study of patients with and without diabetes who underwent decompressive surgery for CSM. PATIENT SAMPLE: Two hundred thirty-six patients without and 42 patients with diabetes were enrolled. Of these, 37 were mild cases and five were moderate cases. Four required insulin. There were no severe cases associated with end-organ damage. OUTCOME MEASURES: Self-report measures include Neck Disability Index and version 2 of 36-Item Short Form Health Survey (SF-36v2), and functional measures include modified Japanese Orthopedic Association (mJOA) score and Nurick grade. METHODS: We compared presurgery symptoms and treatment outcomes between patients with and without diabetes using univariate and multivariate models, adjusting for demographics and comorbidities. RESULTS: Diabetic patients were older, less likely to smoke, and more likely to be on social security disability insurance. Patients with diabetes presented with a worse Nurick grade, but there were no differences in mJOA and SF-36v2 at presentation. Overall, there was a significant improvement in all outcome parameters at 12 and 24 months. There was no difference in the level of improvement between the patients with and without diabetes, except in the SF-36v2 Physical Functioning, in which diabetic patients experienced significantly less improvement. There were no differences in surgical complication rates between diabetic patients and nondiabetic patients. CONCLUSIONS: Except for a worse Nurick grade, diabetes does not seem to affect severity of symptoms at presentation for surgery. More importantly, with the exception of the SF-36v2 Physical Functioning scores, outcomes of surgical treatment are similar in patients with diabetes and without diabetes. Surgical decompression is effective and should be offered to patients with diabetes who have symptomatic CSM and are appropriate surgical candidates.

STUDY DESIGN: Retrospective case-control study/economic analysis. OBJECTIVE: To determine the treatment times required for isolated lumbar decompressions and for combined decompression and instrumented fusion procedures to compare the relative reimbursements for each type of operation as a function of time expenditure by the surgeon. SUMMARY OF BACKGROUND DATA: Under current Medicare fee schedules, the payment for a fusion procedure is higher than of an isolated decompression. It has been recently suggested in the lay press that the greater reimbursement for a lumbar arthrodesis may inappropriately influence the manner in which surgeons elect to treat lumbar degenerative conditions, resulting in what they believe to be a substantial number of unnecessary spinal fusions. METHODS: A consecutive series of 50 single-level decompression cases performed by single surgeon were retrospectively analyzed and compared with an equivalent cohort of subjects who underwent single-level decompression and instrumented posterolateral fusion with autogenous iliac crest bone grafting. The operative reports, office charts, and billing records were reviewed to determine the total clinical time invested by the surgeon and the Medicare reimbursement for each surgery. RESULTS: Relative to the corresponding values of the decompression group, combined decompression and fusion procedures were associated with a longer mean surgical time (134.6 min vs. 47.3 min, P<0.0001), a greater number of postoperative visits (1.0 vs. 3.2, P<0.0001), a higher mean total clinical time expenditure (186.6 min vs. 62.2 min, P<0.0001), and a lower mean dollars received per minute of surgeon time ($12.51 vs. $15.51, P<0.001). CONCLUSIONS: These findings challenge the assertion that spine surgeons have an undue financial incentive to recommend a combined decompression and instrumented fusion procedure over an isolated decompression to patients with symptomatic lumbar degeneration, especially when considering the greater time, effort, and risk characteristic of this more complex operation.

BACKGROUND: Autogenous iliac crest bone is the gold-standard graft for spinal fusion surgery. Unfortunately, there is a frequent incidence of graft site pain that persists well into the postoperative period with complication rates reported in 2.8-39% of patients. Persistent pain lasting at least 2 years is reported in 15-39% of patients. OBJECTIVE: The objective of this work was to determine the incidence of acute and persistent pain as well as patient assessment of graft site appearance following iliac crest bone graft harvest for anterior lumbar interbody fusion (ALIF). The control arms of four randomized prospective multicenter clinical trials evaluating recombinant human bone morphogenetic protein-2 (rhBMP-2) versus autogenous iliac crest bone graft were combined. Two hundred eight patients underwent iliac crest bone graft harvest for ALIF in threaded cylindrical cages or threaded bone dowels. Patients were assessed at each postoperative visit with questionnaires evaluating graft site pain intensity, duration, and appearance. METHODS: Two hundred eight patients underwent iliac crest bone graft harvest for ALIF as the control group of four randomized prospective multicenter clinical trials evaluating rhBMP-2 versus autogenous iliac crest bone graft in threaded cylindrical cages or threaded bone dowels. Most patients in the control group had anterior iliac crest graft harvest, equally from the right and left side. Three grafts (1.4%) were taken from the posterior crest and six (2.9%) were tricortical. Follow-up was obtained at hospital discharge, 6 weeks, 3, 6, 12, and 24 months. A pain evaluation score was made up of two Visual Analog Scales: one scale measuring intensity, the other frequency of pain. For the intensity scale, a rating of "0" meant no pain and "10" was "as bad as it could be." For the frequency scale, a rating of "0" meant pain was present "none of the time" and "10" meant it was present "all the time." Combining these scales, a total score of 20 indicated the worst pain was present all the time. Patients were also questioned about the graft site appearance. RESULTS: Two hundred eight patients underwent iliac crest harvest, and prospective data were available on 202 patients. At hospital discharge, 2 patients (1%) had no pain; this increased to 34 of 199 (17%) at 6 weeks postoperatively and to 85 of 199 patients (43%) at 3 months. However, 41% of patients reported pain at 6 months postoperatively (79/192), and 33% of 168 reported pain at 1 year. One hundred forty-one of 208 patients completed a survey at 24 months, with 31% reporting some level of pain. At hospital discharge, the graft site pain score ranged from 0 to 20 with a mean of 12.8, decreasing to 7.3 at 6 weeks, to 3.8 at 3 months, and to 2.9, 2.4, and 1.8 at 6, 12, and 24 months, respectively. At all time intervals, P values from t tests comparing the mean with 0 were <0.001. Graft site appearance at discharge was good in 49% of patients, fair in 40%, and poor in 11%. At 6 weeks, appearance was good in 69%, fair in 27%, and poor in 5%; at 3 months, it was good in 75%, fair in 24%, and poor in 2%; at 6 months, it was good in 82%, fair in 15%, and poor in 3%; at 12 months, it was good in 82% and fair or poor in 19%; and at 24 months, it was good in 84% and fair or poor in 16%. There was no significant difference between posterior and anterior harvest sites or bicortical grafts, and all were included in the analysis. Right or left side demonstrated no differences. DISCUSSION: This is the first study known to the authors presenting results of prospective data collected in a multicenter study evaluating iliac crest harvest site pain, both intensity and frequency, as well as graft site appearance. The results demonstrate that 31% of patients had persistent pain at 24 months postoperatively and 16% reported fair or poor appearance of their graft site. CONCLUSIONS: Persistent donor site pain remains a problem with harvest of autogenous iliac crest bone graft for spinal fusion. This prospective study, the first such study reported for ALIF, confirms that donor site pain remains a significant postoperative management problem.
