Management of neck pain and associated disorders: A clinical practice guideline from the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration.

PURPOSE: To develop an evidence-based guideline for the management of grades I-III neck pain and associated disorders (NAD). METHODS: This guideline is based on recent systematic reviews of high-quality studies. A multidisciplinary expert panel considered the evidence of effectiveness, safety, cost-effectiveness, societal and ethical values, and patient experiences (obtained from qualitative research) when formulating recommendations. Target audience includes clinicians; target population is adults with grades I-III NAD <6 months duration. RECOMMENDATION 1: Clinicians should rule out major structural or other pathologies as the cause of NAD. Once major pathology has been ruled out, clinicians should classify NAD as grade I, II, or III. RECOMMENDATION 2: Clinicians should assess prognostic factors for delayed recovery from NAD. RECOMMENDATION 3: Clinicians should educate and reassure patients about the benign and self-limited nature of the typical course of NAD grades I-III and the importance of maintaining activity and movement. Patients with worsening symptoms and those who develop new physical or psychological symptoms should be referred to a physician for further evaluation at any time during their care. RECOMMENDATION 4: For NAD grades I-II ≤3 months duration, clinicians may consider structured patient education in combination with: range of motion exercise, multimodal care (range of motion exercise with manipulation or mobilization), or muscle relaxants. In view of evidence of no effectiveness, clinicians should not offer structured patient education alone, strain-counterstrain therapy, relaxation massage, cervical collar, electroacupuncture, electrotherapy, or clinic-based heat. RECOMMENDATION 5: For NAD grades I-II >3 months duration, clinicians may consider structured patient education in combination with: range of motion and strengthening exercises, qigong, yoga, multimodal care (exercise with manipulation or mobilization), clinical massage, low-level laser therapy, or non-steroidal anti-inflammatory drugs. In view of evidence of no effectiveness, clinicians should not offer strengthening exercises alone, strain-counterstrain therapy, relaxation massage, relaxation therapy for pain or disability, electrotherapy, shortwave diathermy, clinic-based heat, electroacupuncture, or botulinum toxin injections. RECOMMENDATION 6: For NAD grade III ≤3 months duration, clinicians may consider supervised strengthening exercises in addition to structured patient education. In view of evidence of no effectiveness, clinicians should not offer structured patient education alone, cervical collar, low-level laser therapy, or traction. RECOMMENDATION 7: For NAD grade III >3 months duration, clinicians should not offer a cervical collar. Patients who continue to experience neurological signs and disability more than 3 months after injury should be referred to a physician for investigation and management. RECOMMENDATION 8: Clinicians should reassess the patient at every visit to determine if additional care is necessary, the condition is worsening, or the patient has recovered. Patients reporting significant recovery should be discharged.

Placebo-controlled trial of cytisine for smoking cessation.

BACKGROUND: Cytisine, a partial agonist that binds with high affinity to the α(4)ß(2) nicotinic acetylcholine receptor, is a low-cost treatment that may be effective in aiding smoking cessation. This study assessed the efficacy and safety of cytisine as compared with placebo. METHODS: We conducted a single-center, randomized, double-blind, placebo-controlled trial. Participants were randomly assigned to receive cytisine or matching placebo for 25 days; participants in both groups received a minimal amount of counseling during the study. The primary outcome measure was sustained, biochemically verified smoking abstinence for 12 months after the end of treatment. Of 1542 adult smokers screened, 740 were enrolled and 370 were randomly assigned to each study group. RESULTS: The rate of sustained 12-month abstinence was 8.4% (31 participants) in the cytisine group as compared with 2.4% (9 participants) in the placebo group (difference, 6.0 percentage points; 95% confidence interval [CI], 2.7 to 9.2; P=0.001). The 7-day point prevalence for abstinence at the 12-month follow-up was 13.2% in the cytisine group versus 7.3% in the placebo group (P=0.01). Gastrointestinal adverse events were reported more frequently in the cytisine group (difference, 5.7 percentage points; 95% CI, 1.2 to 10.2). CONCLUSIONS: In this single-center study, cytisine was more effective than placebo for smoking cessation. The lower price of cytisine as compared with that of other pharmacotherapies for smoking cessation may make it an affordable treatment to advance smoking cessation globally.

A standing posture is associated with increased susceptibility to the sound-induced flash illusion in fall-prone older adults.

Recent research has provided evidence suggesting a link between inefficient processing of multisensory information and incidence of falling in older adults. Specifically, Setti et al. (Exp Brain Res 209:375-384, 2011) reported that older adults with a history of falling were more susceptible than their healthy, age-matched counterparts to the sound-induced flash illusion. Here, we investigated whether balance control in fall-prone older adults was directly associated with multisensory integration by testing susceptibility to the illusion under two postural conditions: sitting and standing. Whilst standing, fall-prone older adults had a greater body sway than the age-matched healthy older adults and their body sway increased when presented with the audio-visual illusory but not the audio-visual congruent conditions. We also found an increase in susceptibility to the sound-induced flash illusion during standing relative to sitting for fall-prone older adults only. Importantly, no performance differences were found across groups in either the unisensory or non-illusory multisensory conditions across the two postures. These results suggest an important link between multisensory integration and balance control in older adults and have important implications for understanding why some older adults are prone to falling.

A direct method and ICER tables for the estimation of the cost-effectiveness of smoking cessation interventions in general populations: application to a new cytisine trial and other examples.

INTRODUCTION: The popularity of smoking cost-effectiveness (CE) analysis has grown rapidly. Differences in models and inputs mean results may not be comparable, and researchers may have to take them on trust because the methods are beyond their expertise and not always transparent. We describe a direct method and tables of results for researchers without specialist knowledge. METHODS: We estimate the health benefit to an individual attributed to an intervention and compute tables of incremental cost-effectiveness ratios (ICERs) for interventions with varying incremental intervention effects and costs. Estimates of life years gained come from the longest epidemiological study. After discounting, adjustments are made for future cessation and relapse. The method is described in simple steps, and conservative inputs are used throughout. RESULTS: To look up an ICER, the user needs only to know the cost of the intervention per smoker and the effect as measured by the percentage of ex-smokers attributable to the intervention at either 6- or 12-month follow-up. Reanalysis of authoritative reports indicates that these ICERs are comparable to those from decision-analytic simulation models. CONCLUSIONS: Researchers can now obtain immediate estimates of the CE of interventions in general populations. The method is easily programmed in a spreadsheet. ICERs are from the payer perspective and exclude offset and societal costs. Interventions in subpopulations will require inputs specific to those populations. Readers who wish to include an adjustment for quality of life can easily do so. The tables might promote a standard approach, with interventions compared on a consistent and transparent basis.

Surgical Considerations for the Acute and Chronic Charcot Neuroarthropathy of the Foot and Ankle.

Charcot neuroarthropathy (CN) of the foot/ankle is a devastating complication that can occur in neuropathic patients. It is a progressive and destructive process that is characterized by acute fractures, dislocations, and joint destruction that will lead to foot and/or ankle deformities. Early diagnosis is imperative, and early treatment may be advantageous, but the condition is not reversible. There is no cure for CN but only treatment recommendations. Ultimate goals of care should include providing a stable limb for ambulation and no ulcerations.

Association between DRD2/ANKK1 Taq1A genotypes, depression and smoking cessation with nicotine replacement therapy.

OBJECTIVES: Tobacco dependence and depression are believed to have a common familial component, most probably genetic, and mood disorders have been reliably associated with failure to stop smoking. Variant genotypes of the Taq1A (DRD2/ANKK1, 32806T, rs1800497) polymorphism have been associated with failure to stop smoking in some studies, but not others. We investigated the association between Taq1A genotypes and smoking cessation, while also considering mental health. MATERIALS AND METHODS: This was a prospective study in 419 smokers who attended a smoking cessation clinic and used standard doses of nicotine replacement therapy. DNA samples and baseline measures including demographics, severity of tobacco dependence, mental health history and history of drug misuse were taken. Smoking cessation at the end of treatment was biochemically verified using expired-air carbon monoxide. RESULTS: We found no simple relation between Taq1A genotype and smoking cessation, although the association between cessation and lifetime depression was significantly modified by genotype. The relationship was such that for those having only common alleles there was no association between depression and stopping smoking, whereas for those with at least one variant allele (A1A2/A1A1) depression was associated with a two-fold reduction in the likelihood of stopping. CONCLUSION: Those having a Taq1A variant allele and a history of depression are likely to experience particular difficulty when trying to stop smoking and may require treatment other than standard doses of nicotine replacement. This finding might explain previous conflicting results for Taq1A and smoking cessation in studies where depression history was not measured, and may help to explain the underlying link between depression and smoking.

'The smoking toolkit study': a national study of smoking and smoking cessation in England.

BACKGROUND: Up-to-date data tracking of national smoking patterns and cessation-related behaviour is required to evaluate and inform tobacco control strategies. The Smoking Toolkit Study (STS) was designed for this role. This paper describes the methodology of the STS and examines as far as possible the representativeness of the samples. METHODS: The STS consists of monthly, cross sectional household interviews of adults aged 16 and over in England with smokers and recent ex-smokers in each monthly wave followed up by postal questionnaires three and six months later. Between November 2006 and December 2010 the baseline survey was completed by 90,568 participants. STS demographic, prevalence and cigarette consumption estimates are compared with those from the Health Survey for England (HSE) and the General Lifestyle Survey (GLF) for 2007-2009. RESULTS: Smoking prevalence estimates of all the surveys were similar from 2008 onwards (e.g 2008 STS=22.0%, 95% C.I.=21.4% to 22.6%, HSE=21.7%, 95% C.I.=20.9% to 22.6%, GLF=20.8%, 95% C.I.=19.7% to 21.9%), although there was heterogeneity in 2007 (chi-square=50.30, p<0.001). Some differences were observed across surveys within sociodemographic sub-groups, although largely in 2007. Cigarette consumption was virtually identical in all surveys and years. CONCLUSION: There is reason to believe that the STS findings (see http://www.smokinginengland.info) are generalisable to the adult population of England.

Noninvasive management of soft tissue disorders of the shoulder: A clinical practice guideline from the Ontario Protocol for Traffic Injury Management (OPTIMa) collaboration.

OBJECTIVES: Objective of this study is to develop an evidence-based guideline for the noninvasive management of soft tissue disorders of the shoulder (shoulder pain), excluding major pathology. METHODS: This guideline is based on high-quality evidence from seven systematic reviews. Multidisciplinary experts considered the evidence of effectiveness, safety, cost-effectiveness, societal and ethical values, and patient experiences when formulating recommendations. Target audience is clinicians; target population is adults with shoulder pain. RESULTS: When managing patients with shoulder pain, clinicians should (a) rule out major structural or other pathologies as the cause of shoulder pain and reassure patients about the benign and self-limited nature of most soft tissue shoulder pain; (b) develop a care plan in partnership with the patient; (c) for shoulder pain of any duration, consider low-level laser therapy; multimodal care (heat/cold, joint mobilization, and range of motion exercise); cervicothoracic spine manipulation and mobilization for shoulder pain when associated pain or restricted movement of the cervicothoracic spine; or thoracic spine manipulation; (d) for shoulder pain >3-month duration, consider stretching and/or strengthening exercises; laser acupuncture; or general physician care (information, advice, and pharmacological pain management if necessary); (e) for shoulder pain with calcific tendinitis on imaging, consider shock-wave therapy; (f) for shoulder pain of any duration, do not offer ultrasound; taping; interferential current therapy; diacutaneous fibrolysis; soft tissue massage; or cervicothoracic spine manipulation and mobilization as an adjunct to exercise (i.e., range of motion, strengthening and stretching exercise) for pain between the neck and the elbow at rest or during movement of the arm; (g) for shoulder pain >3-month duration, do not offer shock-wave therapy; and (h) should reassess the patient's status at each visit for worsening of symptoms or new physical, mental, or psychological symptoms, or satisfactory recovery. CONCLUSIONS: Our evidence-based guideline provides recommendations for non-invasive management of shoulder pain. The impact of the guideline in clinical practice requires further evaluation. SIGNIFICANCE: Shoulder pain of any duration can be effectively treated with laser therapy, multimodal care (i.e., heat/cold, joint mobilization, range of motion exercise), or cervicothoracic manipulation and mobilization. Shoulder pain (>3 months) can be effectively treated with exercises, laser acupuncture, or general physician care (information, advice, and pharmacological pain management if necessary).

Residual attraction to smoking and smoker identity following smoking cessation.

INTRODUCTION: Anecdotal reports suggest that some long-term ex-smokers retain a residual attraction to smoking and a "smoker identity," although little systematic data on this exist. These are important because they may increase the likelihood of relapse. This study aimed to quantify the extent of these characteristics in relation to length of abstinence. METHODS: A postal questionnaire on residual attraction to smoking, smoker identity, and vulnerability to relapse was sent to 1,390 adults known to have been abstinent for 4 weeks after treatment support with a large stop smoking service in England. Time since the end of treatment varied between 6 weeks and 3 years. Three hundred and fifty-seven ex-smokers responded and were included in the analysis. RESULTS: The proportion of ex-smokers reporting a residual attraction to smoking, a smoker identity, and a vulnerability to relapse declined with duration of abstinence (all p < .001), although even among those having 2 years or more of abstinence, 37.4% (95% CI = 27.9%-47.7%) reported some residual attraction and 16.3% (95% CI = 9.6%-25.2%) retained a smoker identity. By contrast, after 2 or more years of abstinence, only 7% thought they would ever return to smoking (95% CI = 2.9%-14.2%). DISCUSSION: The findings suggest that residual attraction to cigarettes is common among long-term ex-smokers, and a significant minority retain a smoker identity. Further studies are needed to determine how far these characteristics are associated with late relapse.

Illicit drug use as a predictor of smoking cessation treatment outcome.

INTRODUCTION: Evidence from cross-sectional survey data suggests a negative association between illicit drug use and smoking cessation. In a prospective clinical cohort, we examined whether illicit drug users were less successful than other smokers when making an attempt to stop smoking. METHODS: A total of 100 smokers attending a tobacco dependence clinic were studied. Pretreatment questionnaire measures of illicit drug use, demographics, health history, and tobacco smoking were taken. Treatment consisted of seven weekly behavioral support sessions plus nicotine replacement therapy or bupropion. Short-term outcome was assessed at the end of the treatment by self-report and carbon monoxide (CO) verification. RESULTS: A total of 24 smokers (24%) had used illicit drugs during the previous 30 days. Drug users were less likely to stop smoking than were nonusers. The difference in CO-verified success rates was 26.1% (29.2% vs. 55.3%, 95% CI = 4.8%-47.4%), and the odds ratio was 0.33 (95% CI = 0.12-0.89). Adjustment for group differences on all the measured background and treatment characteristics affected this result only marginally. DISCUSSION: Illicit drug use appears to have a significant detrimental effect on the success of an attempt to stop smoking. This effect is not explained by differences between drug users and nonusers on established prognostic factors. These first results in a prospective sample support findings from a large U.S. population survey of smoking cessation rates in drug users and nonusers. If these results are corroborated, clinicians treating smokers should consider developing new protocols to improve outcomes in smokers using illicit drugs.

A case report of a double advancement flap closure combined with an Ilizarov technique for the chronic plantar forefoot ulceration.

Soft tissue closure of defects on the plantar surface of the foot continues to be a challenge for the reconstructive surgeon secondarily to the limited number of surgical options and often difficulty of replacing durable and similar soft tissue coverage. Primary closure and skin grafting may not be suitable for the weight-bearing surfaces of the plantar forefoot area, and closure may then be obtained by other means of plastic surgery techniques.

Understanding and using time series analyses in addiction research.

Time series analyses are statistical methods used to assess trends in repeated measurements taken at regular intervals and their associations with other trends or events, taking account of the temporal structure of such data. Addiction research often involves assessing associations between trends in target variables (e.g. population cigarette smoking prevalence) and predictor variables (e.g. average price of a cigarette), known as a multiple time series design, or interventions or events (e.g. introduction of an indoor smoking ban), known as an interrupted time series design. There are many analytical tools available, each with its own strengths and limitations. This paper provides addiction researchers with an overview of many of the methods available (GLM, GLMM, GLS, GAMM, ARIMA, ARIMAX, VAR, SVAR, VECM) and guidance on when and how they should be used, sample size det ermination, reporting and interpretation. The aim is to provide increased clarity for researchers proposing to undertake these analyses concerning what is likely to be acceptable for publication in journals such as Addiction. Given the large number of choices that need to be made when setting up time series models, the guidance emphasizes the importance of pre-registering hypotheses and analysis plans before the analyses are undertaken.

Rapid Aspirin Desensitization is Safe and Feasible in Patients With Stable and Unstable Coronary Artery Disease: A Single-Center Experience.

AIMS: There are limited data on aspirin (ASA) desensitization for patients with coronary disease. We present our experience with a rapid nurse-led oral desensitization regimen in patients with aspirin sensitivity undergoing coronary angiography. METHODS: This single-center retrospective observational study includes patients with a history of ASA sensitivity undergoing coronary angiography with intent to perform percutaneous coronary intervention (PCI). RESULTS: Between January 2012 and January 2017, 24 patients undergoing coronary angiography for stable coronary disease (7 cases) or acute coronary syndromes (non-ST-segment myocardial infarction [NSTEMI; 8 cases], STEMI [9 cases]) underwent aspirin desensitization having reported previous reactions to aspirin. At initial presentation, previous sensitivity reactions were reported as: mucocutaneous reactions in 17 patients (urticaria in 3 [13%], nonurticarial rash in 6 [25%], angio-oedema in 8 [33%]), respiratory sensitivity in 4 (17%), and systemic anaphylactoid reactions in 3 (13%). Seventeen (71%) patients underwent PCI. Desensitization was acutely successful in 22 (92%) patients and unsuccessful in 2 (8%) patients who both had a single short-lived episode of acute bronchospasm treated successfully with nebulized salbutamol. Fifteen successfully desensitized patients completed 12 months of aspirin; no patient had recurrent hypersensitivity reaction. Aspirin was stopped prior to 12 months in 7 patients (replaced by warfarin [1 case], no antiplatelet or single antiplatelet clinically indicated and clopidogrel chosen [4 cases], patient choice without evidence of recurrent hypersensitivity [1 case], and death due to cardiogenic shock following STEMI [1 case]). CONCLUSION: A rapid aspirin desensitization protocol is safe and effective across a broad spectrum of hypersensitivity reactions and clinical presentations.

Non-pharmacological management of persistent headaches associated with neck pain: A clinical practice guideline from the Ontario protocol for traffic injury management (OPTIMa) collaboration.

OBJECTIVES: To develop an evidence-based guideline for the non-pharmacological management of persistent headaches associated with neck pain (i.e., tension-type or cervicogenic). METHODS: This guideline is based on systematic reviews of high-quality studies. A multidisciplinary expert panel considered the evidence of clinical benefits, cost-effectiveness, societal and ethical values, and patient experiences when formulating recommendations. Target audience includes clinicians; target population is adults with persistent headaches associated with neck pain. RESULTS: When managing patients with headaches associated with neck pain, clinicians should (a) rule out major structural or other pathologies, or migraine as the cause of headaches; (b) classify headaches associated with neck pain as tension-type headache or cervicogenic headache once other sources of headache pathology has been ruled out; (c) provide care in partnership with the patient and involve the patient in care planning and decision making; (d) provide care in addition to structured patient education; (e) consider low-load endurance craniocervical and cervicoscapular exercises for tension-type headaches (episodic or chronic) or cervicogenic headaches >3 months duration; (f) consider general exercise, multimodal care (spinal mobilization, craniocervical exercise and postural correction) or clinical massage for chronic tension-type headaches; (g) do not offer manipulation of the cervical spine as the sole form of treatment for episodic or chronic tension-type headaches; (h) consider manual therapy (manipulation with or without mobilization) to the cervical and thoracic spine for cervicogenic headaches >3 months duration. However, there is no added benefit in combining spinal manipulation, spinal mobilization and exercises; and (i) reassess the patient at every visit to assess outcomes and determine whether a referral is indicated. CONCLUSIONS: Our evidence-based guideline provides recommendations for the conservative management of persistent headaches associated with neck pain. The impact of the guideline in clinical practice requires validation. SIGNIFICANCE: Neck pain and headaches are very common comorbidities in the population. Tension-type and cervicogenic headaches can be treated effectively with specific exercises. Manual therapy can be considered as an adjunct therapy to exercise to treat patients with cervicogenic headaches. The management of tension-type and cervicogenic headaches should be patient-centred.

Varenicline in the routine treatment of tobacco dependence: a pre-post comparison with nicotine replacement therapy and an evaluation in those with mental illness.

AIMS: To compare the effectiveness of varenicline with nicotine replacement for smoking cessation and to evaluate the safety and effectiveness of varenicline in people with mental illness. DESIGN: Evaluation of consecutive routine cases before and after the introduction of varenicline. SETTING: National Health Service (NHS) tobacco dependence clinic in London, UK. PARTICIPANTS: A total of 412 cases receiving routine care. INTERVENTION: Seven group support sessions over 6 weeks with either nicotine replacement therapy (NRT) (n = 204) or varenicline (n = 208). MEASUREMENTS: Verified abstinence 4 weeks after quit day, severity of withdrawal symptoms, incidence and severity of adverse drug symptoms, cost per patient treated and cost per successful short-term quitter. FINDINGS: Short-term cessation rates were higher with varenicline than NRT (odds ratio = 1.70, 95% confidence interval = 1.09-2.67). Varenicline was equally effective in those with and without mental illness. Craving to smoke, but not adverse mood, was less severe with varenicline than NRT. The cost per quitter was similar for varenicline and NRT. There was a higher incidence of adverse drug symptoms among those taking varenicline, but these were tolerated by most smokers. There was no evidence that varenicline exacerbated mental illness. CONCLUSIONS: In this setting and with group support varenicline appears to improve success rates over those achieved with NRT, and is equally effective and safe in those with and without a mental illness.

Corrective midfoot osteotomies.

Corrective midfoot osteotomies involve complete separation of the forefoot and hindfoot through the level of the midfoot, followed by uni-, bi-, or triplanar realignment and arthrodesis. This technique can be performed through various approaches; however, in the high-risk patient, percutaneous and minimum incision techniques are necessary to limit the potential of developing soft tissue injury. These master level techniques require extensive surgical experience and detailed knowledge of lower extremity biomechanics. The authors discuss preoperative clinical and radiographic evaluation, specific operative techniques used, and postoperative management for the high-risk patient undergoing corrective midfoot osteotomy.

Use of circular external fixation for combined subtalar joint fusion and ankle distraction.

The authors discuss a novel technique not previously published that incorporates a subtalar joint arthrodesis with an ankle joint arthrodiastasis as an alternative to a tibiotalocalcaneal arthrodesis. Young and active patients who experience refractory pain and stiffness to the rearfoot and ankle secondary to combined severe subtalar and ankle arthrosis are suitable candidates for this surgical procedure. This new approach is based on sound principles in the treatment of severe arthrosis affecting the ankle and subtalar joint. The authors are currently prospectively reviewing their surgical experience with this procedure and believe that it provides an alternative option for the patient, with potentially promising long-term results.

Salvage of the first ray with concomitant septic and gouty arthritis by use of a bone block joint distraction arthrodesis and external fixation.

Gouty arthropathy about the first metatarsal-phalangeal joint with a superimposed deep infection poses a great challenge to the foot and ankle surgeon. The inflammatory nature of gout compromises the soft-tissue envelope and vasculature to the area. Acute gouty arthropathy is usually a contraindication to surgical intervention secondary to wound-healing complications and possible vasospasm leading to tissue necrosis. However, if deep infection is present this must be managed with adequate surgical débridement followed by delayed soft-tissue and osseous reconstruction to prevent amputation. The authors present an exceptional clinical manifestation of gouty arthropathy of the first metatarsal-phalangeal joint concomitant with deep abscess and osteomyelitis and the surgical approach taken to afford functional limb salvage.

Surgical management of diabetic foot infections and amputations.

The incidence of diabetes with severe foot infections (eg, necrotizing fasciitis, gas gangrene, ascending cellulitis, infection with systemic toxicity or metabolic instability) has risen significantly during the past decade. Foot infections are a major cause of hospitalization and subsequent lower extremity amputation among patients with diabetes mellitus who have a history of a preexisting ulceration. Surgical management often is required to address severe diabetic foot infections because they can be limb- or life-threatening. Critical limb ischemia, neuropathy, and an immunocompromised host, which often are associated with diabetic foot infections, complicate treatment and are associated with a poorer prognosis.
