Vertigo. A practical approach to diagnosis and treatment.

BACKGROUND: Vertigo is a symptom that has diverse causes. The diagnosis may remain elusive even after exhaustive clinical enquiry and there is often also a general perception that little can be done in many cases apart from prescribing vestibular suppressant drug therapy. Many patients are therefore treated symptomatically without a specific diagnosis being made. OBJECTIVE: To discuss the diagnosis and management of the more common vestibular syndromes. DISCUSSION: Many conditions such as benign positional vertigo and migraine can be successfully diagnosed and treated without the need for referral. Exercise therapy rather than chronic drug use should be the mainstay of treatment in patients with 'uncompensated' vestibular lesions. This article provides a practical approach to vertigo that can lead to a successful clinical outcome in many cases.

[An analysis of the clinical effectiveness of manual therapy in cervical vertebrae syndrome].

The aim of this review was to evaluate the clinical effectiveness of manipulation techniques as a therapy for cervical pain syndromes. Only few randomized trials have been published on this matter. They come to contradictory conclusions. In this unclear situation, the prescribing physician should note that there is no scientific evidence to suggest that manipulations are superior to other forms of treatment, for instance exercise therapy. Further research in this area seems therefore mandatory.

A multicenter study of a new inotropic agent, piperanometozine (OPC-8212) in congestive heart failure: clinical improvement during short-term treatment.

Piperanometozine (OPC-8212) is a new, orally effective inotropic agent. To evaluate the efficacy of this agent on systemic hemodynamics and clinical symptoms in patients with congestive heart failure, a multicenter study was performed. Thirty four patients with New York Heart Association (NYHA) functional classes II to IV and initially treated with digitalis were enrolled from ten centers. After a washout period of one or two weeks (placebo period), digitalis was replaced by piperanometozine (30 or 60 mg/day) for four weeks, while other drugs were continued. Clinical symptoms, routine physical findings, electrocardiogram, chest roentgenogram, echocardiogram, exercise tolerance time, and routine laboratory data were obtained in 34 patients. Four patients were withdrawn from the study before completion. After the withdrawal of digitalis, heart rate was increased and ejection fraction was decreased. Exercise tolerance time was increased while other parameters were unchanged. At the end of the treatment period with piperanometozine, ejection fraction significantly (p less than 0.05) increased with a decrease in LV end-systolic volume (p less than 0.05), whereas heart rate and blood pressure remained unchanged. Systolic blood pressure/LV end-systolic volume (P/V index) tended to decrease after the withdrawal of digitalis and increase during piperanometozine therapy. Exercise tolerance time was further increased (p less than 0.01) and NYHA functional class was improved in 11 patients, whereas it worsened in only one patient. No major adverse effects were observed. These results indicate that a short-term therapy of oral piperanometozine restored the depressed cardiac performance of the heart and improved clinical symptoms in patients with congestive heart failure. Thus, this promising agent deserves further clinical study in long-term trials.

The influence of intense exercise-based physical therapy program on back pain anticipated before and induced by physical activities.

BACKGROUND CONTEXT: Pain anticipated before and induced by physical activities has been shown to influence the physical performance of patients with chronic back pain. Limited data exist as to the influence of treatment on this component of pain. PURPOSE: This study attempted to determine if pain anticipated before and induced by physical activities was altered during an exercise-oriented physical therapy program for chronic back pain. STUDY DESIGN/SETTING: Subjects were recruited from three physical therapy sites with similar spine rehabilitation programs that used intense exercise delivered in a group format. During the recruitment period, 70 subjects with chronic low back pain and disability agreed to participate and complied with recommended treatments. The primary outcome measures were anticipated and induced pain as assessed by visual analog scales (VAS) during six tests of back flexibility and strength. Additional outcome measures included the performance levels of these six tests (trunk flexion, extension, straight leg raising, back strength, lifting from floor to waist and waist to shoulder height), global back and leg VAS and Oswestry Low Back Pain Disability Questionnaire scores. METHODS: At evaluation for the spine rehabilitation programs, we recorded the anticipated and induced pain levels associated with the six tests of back function, the performance levels on each test and global pain and disability scores. Subjects then participated in the spine rehabilitation program that consisted of intense exercise delivered up to three times per week, for 2 hours over a period of 6 weeks. All outcome measures were reassessed at discharge. Pre- and posttreatment outcome scores were statistically compared using paired sample t tests and chi-squared test. Spearman correlation coefficients were used to compare anticipated and induced pain results with global back and leg pain VAS scores, Oswestry scores and physical performance levels for each physical test. RESULTS: Most measures of anticipated and induced pain improved between evaluation and discharge. Improvements were noted for global back pain (p<.001), leg pain (p=.001), disability (p<.001) and performance on each physical testing (p<.001) after treatment. Performances on all physical testing correlated with anticipated and induced pain for all tests at evaluation but only for measures of flexibility at discharge. Improvements in global pain and disability correlated with improvements in anticipated and induced pain with physical testing. CONCLUSION: Anticipated and induced pain with physical activities was lessened after physical therapy using exercise. Anticipated and induced pain with physical activities related to physical performance levels, global pain and disability ratings. These findings may help explain how exercise exerts a positive influence on chronic back pain and disability.

[Exercise training in heart failure].

BACKGROUND: In patients with chronic heart failure, exercise limitation cannot be exclusively attributed to cardiac dysfunction. During progression of the disease, peripheral factors have a growing impact on functional capacity. Chronic underperfusion of skeletal muscles, inactivity and a harmful effect of neuroendocrine stimulation lead to a myopathy syndrome characterized by atrophy, a shift in muscle fiber type and a loss of capillaries and mitochondria, which cause reduced muscle strength and aerobic capacity. Unlike left ventricular systolic function, which is a poor predictor of exercise tolerance in patients with chronic heart failure, parameters characterizing the myopathy syndrome correlate well with functional capacity. In the last 20 years, numerous studies have demonstrated that chronic heart failure patients in NYHA classes II and III benefit from physical training without deterioration of their cardiac function. EFFECTS OF EXERCISE TRAINING: Physical activity primarily improves muscle function and increases maximal as well as submaximal exercise capacity. Advantageous effects have also been observed with regard to neuroendocrine stimulation. The effect on central hemodynamics is much smaller and indirectly mediated by a trend towards decreased peripheral resistance. Left ventricular diameters, ejection fraction and filling pressures do not show significant changes. The gain in exercise capacity is usually accompanied by an improvement in symptom status and quality of life. Recent studies indicate that prognosis may also be improved by exercise training. CONVERSION INTO CLINICAL PRACTICE: Although continuous exercise training (mainly by use of cycle ergometry) has been investigated most thoroughly, there is an increasing number of studies reporting beneficial effects of interval and resistance training. Before starting a standardized training program, functional limitation and training intensity should be determined by an appropriate stress test. During the first training sessions, patients should always be supervised by a physician. In order to increase efficiency and feasibility of the exercise therapy, home-based training should be engaged as soon as a stable condition during repeated training sessions has been proven.

Effect of diet and weight reduction in hypertension.

Weight reduction by a low-energy diet and a high-polyunsaturates-, fiber- and potassium-rich diet may be independently useful to hypertensives. To study the effect of such diets, 416 hypertensives were randomized to either a low-energy cardiovasoprotective (CVP) diet (Group A; n = 106), a low-energy usual diet (Group B; n = 104), an optimal-energy CVP diet (Group C; n = 104), or an optimal-energy, usual pre-experimental diet (Group D; n = 102) plus drug therapy in a single-blind and controlled fashion. Groups A and B received significant (p less than 0.02) fewer calories per day than Groups C and D. Groups A and C also received significantly (p less than 0.02) more calories per amount of complex carbohydrates, polyunsaturates, potassium, and magnesium than did Groups B and D. Dietary compliance and drug intake was checked weekly. After 3 months, there was a significant fall in mean serum cholesterol (p less than 0.01) and mean serum triglycerides (p less than 0.05) in Group A compared with Group D. Group A and B patients had a loss of around 10kg of mean body weight, with no weight change seen in Group D. Weight loss was associated with a significant fall in systolic and diastolic pressures in both Group A (22/18mmHg) and Group B (16/13mmHg) compared with Group D at the end of the study. Group C patients also showed a significant fall in pressure (13/10mmHg) compared with Group D. Drug therapy, exercise, and salt intake were similar in all the groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Initiating oral glucose-lowering therapy with metformin in type 2 diabetic patients: an evidence-based strategy to reduce the burden of late-developing diabetes complications.

A major aim of glucose-lowering therapy in people with diabetes is to delay or prevent the late-developing complications of diabetes that threaten the quality and duration of life. While intensive interventions to control hyperglycaemia may impair well-being to some extent, the balance of quality of life is usually highly positive. Diet and exercise therapy remains the cornerstone of management, and should usually be given a trial alone first. However, the magnitude and duration of benefit from this intervention is insufficient for most people. More frequent, early, use of metformin is an evidence-based strategy for reducing the risk of adverse outcomes of diabetes in people with type 2 diabetes with sub-optimal glucose control on lifestyle measures alone. This has been recognised in recent evidenced-based guidelines from the UK National Institute for Clinical Excellence and from Diabetes UK, which now support the use of metformin as initial pharmacological therapy for all people without contraindications to the drug. Other national and local guideline committees should consider updating their recommendations on diabetes management in line with these findings.

Oral photochemotherapy in lichen planus (LP) and mycosis fungoides (MF): ultrastructural modifications of the infiltrating cells.

Six patients (5 with mycosis fungoides and 1 with lichen planus) treated with PUVA, were subjected to biopsy of lesional skin before and during oral photochemotherapy. Ultrastructurally, a reduction in the density of cellular infiltrate was observed in the superficial dermis. In the same areas, necrotic cellular changes were observed. PUVA therapy exercises its beneficial effect by direct destruction of these cells.

Amount of health care and self-care following a randomized clinical trial comparing flexion-distraction with exercise program for chronic low back pain.

BACKGROUND: Previous clinical trials have assessed the percentage of participants who utilized further health care after a period of conservative care for low back pain, however no chiropractic clinical trial has determined the total amount of care during this time and any differences based on assigned treatment group. The objective of this clinical trial follow-up was to assess if there was a difference in the total number of office visits for low back pain over one year after a four week clinical trial of either a form of physical therapy (Exercise Program) or a form of chiropractic care (Flexion Distraction) for chronic low back pain. METHODS: In this randomized clinical trial follow up study, 195 participants were followed for one year after a four-week period of either a form of chiropractic care (FD) or a form of physical therapy (EP). Weekly structured telephone interview questions regarded visitation of various health care practitioners and the practice of self-care for low back pain. RESULTS: Participants in the physical therapy group demonstrated on average significantly more visits to any health care provider and to a general practitioner during the year after trial care (p < 0.05). No group differences were noted in the number of visits to a chiropractor or physical therapist. Self-care was initiated by nearly every participant in both groups. CONCLUSION: During a one-year follow-up, participants previously randomized to physical therapy attended significantly more health care visits than those participants who received chiropractic care.

Peripheral arterial disease. A systemic disease extending beyond the affected extremity.

Peripheral arterial disease (PAD) is a manifestation of the atherosclerotic process and is associated with an increased risk of cerebrovascular disease, cardiovascular disease, and death. Clinicians should consider screening both asymptomatic and symptomatic patients with the ankle-brachial index, a test with a high sensitivity and specificity. For those patients with PAD, atherosclerotic risk factors (such as smoking, dyslipidemia, hypertension, and diabetes mellitus) should be aggressively treated. In addition to exercise therapy, there is evidence available to support the use of aspirin, clopidogrel, lipid-lowering agents, pentoxifylline, and cilostazol.

Ottawa panel evidence-based clinical practice guidelines for therapeutic exercises and manual therapy in the management of osteoarthritis.

BACKGROUND AND PURPOSE: Osteoarthritis (OA) affects a large and growing proportion of the population. The purpose of this project was to create guidelines for the use of therapeutic exercises and manual therapy in the management of adult patients (>18 years of age) with a diagnosis of OA. All stages of the disease were included in the analysis, and studies of patients who had recent surgery or other rheumatologic, musculoskeletal, or spinal problems or of subjects without known pathology or impairments were excluded. METHODS: The Ottawa Methods Group used Cochrane Collaboration methods to find and synthesize evidence from comparative controlled trials and then asked stakeholder groups to nominate representatives to serve on a panel of experts. The Ottawa Panel agreed on criteria for grading the strength of the recommendations and their supporting evidence. Of the 609 potential articles on therapeutic exercises for OA that were identified, 113 were considered potentially relevant, and 26 randomized controlled trials and controlled clinical trials were ultimately used. RESULTS: Sixteen positive recommendations of clinical benefit were developed for therapeutic exercises, especially strengthening exercises and general physical activity, particularly for the management of pain and improvement of functional status. Manual therapy combined with exercises also is recommended in the management of patients with OA. DISCUSSION AND CONCLUSION: The Ottawa Panel recommends the use of therapeutic exercises alone, or combined with manual therapy, for managing patients with OA. There were a total of 16 positive recommendations: 13 grade A and 3 grade C+. The Ottawa Panel recommends the use of therapeutic exercises because of the strong evidence (grades A, B, and C+) in the literature.

Physical exercise for patients with cystic fibrosis: a review.

Cystic fibrosis (CF) is an inherited, chronic disease which mainly affects the lungs and the nutrition. Intensive treatment has gradually improved the outcome for the patients. Exercise therapy has been increasingly advocated to be included in the CF regimen. Our own studies indicate that both short-term and long-term training ameliorate the physical conditions for CF patients, that there is no danger for well-trained CF patients--both boys and girls--to take part even in vigorous, prolonged exercises, and that CF patients might have a positive attitude toward physical activities. Of course, all physical activities have to be individually designed. A review of the literature is also given: The specific ventilatory factors in CF, the limitations of exercise, the problem with exercise-induced asthma, the training effect on lung drainage, on lung function, on infections, on biochemical and hormonal variables, on nutrition and the gastrointestinal tract, on the musculoskeletal apparatus, and on the mind. Nearly all these reports are favorable for a carefully monitored, high activity in CF patients. Practical considerations for activities are given.

Reduced oxidative susceptibility of LDL from patients participating in an intensive atherosclerosis treatment program.

The goal of this investigation was to determine whether participation in an atherosclerosis treatment program would reduce the oxidative susceptibility of LDL from patients with coronary artery disease. The treatment program included intensive exercise therapy, stress management, and consumption of a diet containing 10% fat. The size and antioxidant and lipid contents of LDL particles from 25 patients were analyzed at baseline and after 3 mo of therapy. The susceptibility of LDL to copper-mediated oxidation was measured by a conjugated diene assay and headspace gas chromatography (HSGC). Atherosclerosis treatment significantly reduced plasma total cholesterol and apolipoprotein B concentrations and the molar ratio of LDL cholesterol ester to apolipoprotein B (P < 0.01). The LDL content of alpha-tocopherol and beta-carotene was increased (27% and 17%, respectively, P < 0.04) and the molar ratio of LDL cholesterol ester the sum of LDL alpha-tocopherol and LDL beta-carotene decreased from 159 at baseline to 122 at 3 mo (P < 0.01). The lag phase of LDL conjugated diene formation increased 24%, whereas the maximum rate of oxidation slowed 29% (P < 0.01). As assessed by HSGC, copper-catalyzed formation of volatile lipid oxidation products was reduced 15% (P < 0.007); the reduction in volatiles was correlated with an increase in the alpha-tocopherol content of LDL (r=-0.48, P < 0.01). The principal determinants of reduced LDL oxidative susceptibility were the particle contents of alpha-tocopherol and beta-carotene. To our knowledge, this is the first report to document a reduction in LDL oxidation in coronary artery disease patients undergoing atherosclerosis-reversal therapy.

Exercise and hypertension. Maximizing the benefits in patients receiving drug therapy.

Aerobic exercise may prevent hypertension and reduce blood pressure and mortality in hypertensive patients and those at high risk for coronary artery disease. Supervised aerobic exercise at an intensity of 70% to 80% of maximal aerobic capacity is recommended to achieve cardiovascular conditioning and other health benefits. When antihypertensive drug therapy is required, physicians should choose an agent that has favorable secondary effects, including hemodynamic responses to exercise. The most favorable effects are achieved with calcium channel blockers, angiotensin-converting enzyme inhibitors, alpha blockers, and central alpha agonists. The effects of diuretics are less desirable, and beta blockers should be a last choice for hypertensive patients who are physically active.

Spinal manipulative therapy in sports medicine.

Spinal manipulation or manual therapy is becoming an increasingly popular method of treating athletes with spinal problems. The primary theoretic basis for the claimed beneficial results of manipulation is the restoration of motion with subsequent effect on ligamentous adhesions, muscle spasm, disk nutrition, and central nervous system endorphin systems. The concept of joint barriers has been developed to differentiate among exercise therapy, mobilization, and manipulation. Research trials suggest that spinal manipulation is beneficial in relieving or reducing the duration of acute low back pain and acute neck pain but has much less effect on chronic low back pain and neck pain. There is evidence that manipulation increases certain parameters of motion of the spine but this evidence is not yet conclusive. There are a wide variety of manipulative procedures that are utilized to manipulate the spine to increase range of motion, and the selection of the procedures is based on manual diagnostic skills. Manipulation, however, is not a benign procedure and has been implicated in the aggravation of disk herniation or bony fractures as well as the precipitation of vertebrobasilar artery occlusion.

Compliance with cardiovascular disease prevention strategies: a review of the research.

The efficacy of cardiovascular risk-reduction programs has been established. However, the extent to which risk-reduction interventions are effective may depend on adherence. Non-compliance, or non-adherence, may occur with any of the recommended or prescribed regimens and may vary across the treatment course. Compliance problems, whether occurring early or late in the treatment course, are clinically significant, as adherence is one mediator of the clinical outcome. This article, which is based on a review of the empirical literature of the past 20 years, addresses compliance across four regimens of cardiovascular risk reduction: pharmacological therapy, exercise, nutrition, and smoking cessation. The criteria for inclusion of a study in this review were: (a) focus on cardiovascular disease risk reduction; (b) report of a quantitative measure of compliance behavior; and (c) use of a randomized controlled design. Forty-six studies meeting these criteria were identified. A variety of self-report, objective, and electronic measurement methods were used across these studies. The interventions employed diverse combinations of cognitive, educational, and behavioral strategies to improve compliance in an array of settings. The strategies demonstrated to be successful in improving compliance included behavioral skill training, self-monitoring, telephone/mail contact, self-efficacy enhancement, and external cognitive aids. A series of tables summarize the intervention strategies, compliance measures, and findings, as well as the interventions demonstrated to be successful. This review reflects the progress made over two decades in compliance measurement and research and, further, advances made in the application of behavioral strategies to the promotion of cardiovascular risk reduction.
