Though the size of the pedicles varies from region to region and from individual to individual discount levitra 20mg without prescription impotence education, one can be comfortable that a 13-gauge cannula (0 purchase levitra 10 mg with visa erectile dysfunction doctors in sri lanka. When the size of the pedicle (or its absence in neoplastic disease) precludes a transpedicular approach, a parapedicular route may be necessary. This route takes the entry device along the lateral margin of the pedicle and above the tranverse process. In the thoracic spine, this trajectory is generally along the junction of the rib with the adja- cent transverse process and vertebral body (Figure 1. The costotransverse joint is the junction of the rib and transverse process, with the intervening space filled with the costotransverse ligament. The parapedicular needle entry point will be along the lateral and poste- rior vertebral border in the paraspinal soft tissues. Venous bleed- ing is common here, but this is usually self-limiting as long as no co- agulopathy exists. Occasionally, the posterior costophrenic sulcus con- tains lung that bulges beyond the border of the rib, making pneumothorax also possible. The bones of the vertebra make up part of the central skeleton, in- side of which the elements of the blood are made. This connection provides one of the main avenues for cement leakage during vertebroplasty or kyphoplasty. The venous route most important for potential leakage is through the pos- terior vertebral wall, communicating with the veins in the epidural space. Venous leak anterior or laterally can result in cement mi- gration into central veins carrying blood to the lungs (resulting in pul- monary emboli). Together with the ligamentous attachments, these elements allow the vertebrae to move through bending and rotation. However, these discs and joints wear and may be the source of pain caused by degeneration. The image-guided interventionist must deal with these structures during discography, percutaneous discectomy, intradiscal electrothermal therapy, facet blocks, and dorsal ramus neurolysis. The intervertebral discs are composed of an outer ring of fibrocarti- lage called the annulus fibrosis (Figure 1. The annulus is attached to the cartilaginous endplates of the vertebrae and constrains the inner disc core called the nucleus pulposus. It is thin posteriorly, which coincides with the area most commonly as- sociated with annular tears and disc herniations. The outer annular fibers, which are more densely packed, are referred to as Sharpey’s fibers. It is composed of collagen fibrils that are embedded in a proteoglycan ma- trix that contains water. With aging and degeneration, water is lost and the nucleus becomes progressively fibrotic and smaller. This variation requires different imaging angulation to enter the disc without obstruction by the adjacent vertebral margins. Appropriate im- aging angulation is necessary for accurate needle placement in discog- raphy and percutaneous disc therapy. The apophyseal or facet joints are paired joints between the poste- rior elements of two adjacent vertebrae. They are curved joints that are oriented obliquely to the sagittal plane (Figure 1. The nerve sup- ply is from the medial division of the dorsal ramus of the spinal nerve that reaches the joint from the nerve above and below the joint on the ipsilateral side (Figure 1. The joint is believed to be a source of non- radiating axial pain that is typically aggravated by hyperextension and rest. Because the joint is curved, image guidance can be confusing and entry into the joint may be difficult, particularly when there is degen- erative disease. A small synovial recess along the superior and inferior margins of the joint will allow access without passing through the curved bone margins. As they rarely have prolonged therapeutic ben- efit, neurolysis of the joint nerve supply with chemical or radiofre- quency (RF) ablation is most often used for long-term pain control. These innervations arise from medial branches from both above and below each joint.

The antidepressant discount levitra 10mg erectile dysfunction and injections, imipramine (Tofranil) effective 10mg levitra erectile dysfunction 23, mentioned above in relation to treating urgency and frequency, taken just before going to bed, has also been found to be effective in many cases. Incontinence Incontinence, what appears to be the involuntary release of urine, may be a slight and an occasional problem in MS, or it may prove to be a continuous problem. However, in each case it provokes anxiety and concern, for socially as much as physically it can be a difficult and embarrassing symptom to have occur unexpectedly. Bladder spasms may be causing this difficulty – technically called ‘incontinence’ – or your bladder muscle PROBLEMS WITH URINATION AND BOWELS 49 may be so weak that you have released urine before realizing it. In addition, sometimes you might not at first realize that you are wet because of reduced sensations in your pubic area. Sanitary protection (absorbent pads) can be used, even if only for maintaining confidence when you are not near a convenient toilet. Pads and liners are available in a wide variety of shapes and styles to suit different people and different clothing styles, but there is much less choice when they are supplied on prescription. Waterproof undersheets and absorbent bed sheets can also be very convenient, to minimize the effect of occasional accidents. If these procedures and/or the drugs mentioned above in relation to urgency and frequency do not work, other professional investigations may well be needed to determine the cause of the problems, and how best they might be managed. Catheterization Although your major concern may be incontinence, there may also a problem with urine retention in the bladder as well – for the bladder may not completely empty, which can lead to serious infection. Thus as an extra precaution, if one of the causes of the incontinence is retention of urine in your bladder, the use of ‘intermittent self-catheterization’ (ISC) Figure 4. A catheter (a thin plastic tube) is threaded through your urethra – the opening at tip of the penis, or just above the vagina – into your bladder, and this drains any remaining urine. You will need to wash yourself thoroughly before using this technique, and you may need to use a lubricant (something like K-Y Jelly) to assist the access of the tube, but modern catheters are low friction types and need no lubricant (such as ‘Lofric’ and ‘Speedicath’ types). You should not use a catheter (tube) which appears to be worn, stiff or damaged in any way. Undertaken regularly, several times a day, this method usually helps substantially. A nurse or doctor will explain how to undertake this procedure, and how to clean the catheter thoroughly. For the most part, although the procedure may seem very difficult, many people adapt well to it, as long as it is seen as a routine process. If you are able to write and to feed yourself, even if you have some eyesight problems, ISC should be possible. There is another reason why ISC can be of value, in that regularly undertaken, it is a means of ‘training’ the bladder to fill and empty as the urine is released: the bladder muscle contracts, expanding again as urine fills the bladder. Urine retention and voiding problems As we have noted above, many people with MS have problems not only with urgency or frequency, but also with some urine retention in the bladder. If this is the case, do not reduce your fluid intake substantially, because this will increase the risk of urinary infection (urine as a waste product is not being diluted). A useful rule of thumb is the colour of your urine: if it is dark yellow to brown in colour, then almost certainly you are not taking in enough fluid. There are some useful guidelines which should help you: • Drink at least 2 litres (or just over 3 pints) of liquid a day. Cranberry juice will also help to provide the vitamin C lost through reducing the intake of citrus fruits/juices. PROBLEMS WITH URINATION AND BOWELS 51 Hesitancy and ‘full bladder’feeling Although this is a frustrating problem, often urination will start after a couple of minutes, so be patient! Sometimes tapping very lightly on your lower abdomen – but not too hard – will help; this often produces a reflex reaction of urination. There have recently been trials of a hand-held vibrating device which, when held against your lower abdomen if you are still sensitive in this area, seems to work quite well by increasing urinary flow and leaving less urine in your bladder. Of course, other time-honoured techniques may work, including turning a tap on and hearing the sound of running water! A more direct method is to stimulate the urethra gently, at the tip of the penis or just above the vagina, with a clean finger or damp tissue.

Physical activity is described as bodily movement produced by skeletal muscles that requires energy expenditure and produces progressive healthy benefits 20 mg levitra free shipping erectile dysfunction question, for example walking order 10 mg levitra amex erectile dysfunction drugs thailand, housework, etc. Exercise is a type of physical activity that is planned, structured and repeti- tive, involving bodily movement performed to improve or maintain one or more components of physical fitness (Leon, NIH Consensus Statement, 1997). In 1997 the Health Education Board for Scotland (HEBS) devised a two-stage approach to encouraging the Scottish population to become more active. Stage one The first stage of the recommendation encourages realistic and achievable exercise prescription for the majority of the population. An active lifestyle does not require a structured exercise programme, but it encourages an increase in daily activity where activity is accumulated over a day (Pate, et al. This proved a change in philosophy; previously the health message invoked a strenuous, more formal type of training. The message behind the first stage encourages moderate intensity exercise, accumulating 30 minutes or more per day on most, preferably all, days of the week (Pate, et al. The activity can be accumulated in multiple small bouts of activity, for example three ten-minute bouts of walking. Stage one targets adults who are currently inactive or who are not regularly active, and aims to encourage an accumulation of moderate intensity activity on most days of the week. This stage encourages active living, using the stairs instead of the escalator, walking the children to school instead of driving, etc. Despite the intensity being too low to gain significant improvements in aerobic fitness Franklin (1993),ACSM (2001) and Blair and Church (2004) have shown that activity at this lower intensity will offer substantial benefits across a broad range of health outcomes. These benefits include: • improved bone density; • improved glucose tolerance; • reduced body fat; • reduced total cholesterol and triglycerides; • reduced risk of developing high blood pressure; • psychosocial well being. In addition, when subjects become more active by accumulated activity they may start to consider participation in more structured activity, as in stage two. All CR patient groups and sedentary individuals should be encouraged to be more active as well as take part in structured activity. Exercise Prescription 99 Stage two The second stage targets adults who are already achieving stage one. In addi- tion to the more active lifestyle in stage two, there is a need for these indi- viduals to achieve exercise overload. The exercise prescription for these individuals must be at a higher intensity, with longer duration of continuous or intermittent activity. A frequency of three to five times per week is advo- cated for these patients (Pollock, et al. Exercise prescribers can motivate sedentary individuals to initiate and accu- mulate activity into their lifestyle by using stage one. By targeting patients who already engage in an active lifestyle, exercise prescribers can introduce new activities, integrate the FITT principles and encourage long-term adherence to exercise. Cardiac rehabilitation structured exercise classes will provide an ideal method to deliver exercise to these individuals. They may present with a variety of self-motivating and limiting factors and differing experiences of exercise. It is the role and responsibility of the exercise leader and CR team to work in partnership with the patient and family to prescribe and deliver a safe, effective and enjoyable experience of both activity and exercise. PHASE I CARDIAC REHABILITATION Phase I is the in-patient stage and includes medical evaluation, reassurance and education, correction of cardiac misconceptions, risk factor assessment, mobilisation and discharge planning SIGN (2002). Anterior infarcts often result in greater left ventricular dysfunction (BACR, 2000), and, as a consequence, exercise tolerance may be limited. Progression should vary according to the stability of the patient’s condition during recov- ery, with higher risk or more debilitated patients progressing more slowly than lower risk, uncomplicated ones (AACVPR, 1999). Previously, patients were often kept on bed rest for many weeks following a cardiac event. However, it is now recognised that prolonged period of immo- bilization can lead to deep vein thrombosis, pulmonary embolism, de- conditioning, increased anxiety and depression (BACR, 1995). Over the years the period of bed rest and length of inpatient stay has gradually reduced. Patients post-MI are commonly allowed to sit up after a short period of bed rest, e. A prolonged period of bed rest may be required for patients who are haemodynamically unstable, or for those who have suffered shock, heart failure or serious arrhythmia.

For example cheap 20 mg levitra overnight delivery erectile dysfunction treatment yoga, participants should be asked if they achieved the activity goals set during the previous consultation levitra 10mg on line erectile dysfunction devices diabetes. If clients did not achieve their goals, then the reasons for this should be explored and new goals set. For example, did they encounter any barriers to activity or risky situations that caused a lapse or relapse from activity? Assessing the individ- uals’ current activity levels and comparing them to the first activity assessment can inform individuals if their activity levels have increased, been maintained or declined over the past six months. Individuals who have increased their activity or remained regularly active should be praised for their achievements. However, barriers to activity, problem solving, goal setting and relapse pre- vention strategies should be discussed with all individuals to ensure they have acquired the necessary skills to help them remain active in the future. Maintaining Physical Activity 211 Phone calls can also be used to provide individuals with support for remain- ing active after an initial exercise consultation. The information recorded during the exercise consultation should be used to guide the phone calls. The phone call may involve discussing any problems the individuals are experi- encing in achieving their activity goals, attending community exercise pro- grammes and remaining active. EFFECT OF EXERCISE CONSULTATION TO INCREASE AND MAINTAIN PHYSICAL ACTIVITY Several randomised controlled trials have found the exercise consultation to be effective in promoting and maintaining physical activity in non-clinical and clinical populations (Loughlan and Mutrie, 1997; Lowther, et al. A recent study of sedentary people with type II diabetes found that the exer- cise consultation was more effective than standard exercise information in promoting and maintaining physical activity for 12 months (Kirk, et al. Current research provides support for the exercise consultation in CR set- tings (Hughes, et al. A pilot study found that the exercise con- sultation improved short-term (four weeks) adherence to physical activity after completion of a phase III supervised exercise programme (Hughes, et al. A recent randomised controlled trial compared the longer-term effect of the exercise consultation with standard exercise information on mainte- nance of physical activity in 70 cardiac patients who had completed an 11-week phase III supervised exercise programme (Hughes, et al. Physical activity was assessed using a questionnaire, stage of change for exer- cise behaviour and accelerometry at baseline (immediately after programme completion), at six and 12 months follow-up. At baseline, both groups were regularly physically active (determined by questionnaire and stage of change), as patients had recently completed an exercise programme. Participation in moderate to vigorous physical activity, measured by questionnaire and accelerometry, was maintained in the experimental group over the 12-month study period. In contrast, self-reported physical activity significantly decreased in the control group from baseline to six and 12 months and total accelerom- etry counts per week decreased by 8% from baseline to 12 months. Further- more, a higher proportion of experimental patients was regularly physically active (i. These findings suggest that the exercise consultation 212 Exercise Leadership in Cardiac Rehabilitation successfully maintained physical activity for 12 months after completion of a phase III exercise programme. Implementing the exercise consultation Research suggests that the exercise consultation is an effective intervention for maintaining physical activity for 12 months following completion of phase III exercise-based cardiac rehabilitation (Hughes, et al. Presently, patients completing phase III can attend phase IV mainte- nance exercise programmes in the community. Furthermore, some patients may not be able to attend structured phase IV programmes due to barriers associated with supervised exercise training, including transportation problems, limited access, work and domestic conflicts. Furthermore, the intervention could be used to facilitate patients’ progression from phase III hospital-based exercise pro- grammes to community-based programmes or independent exercise. Thus, the exercise consultation could be routinely provided to cardiac patients on com- pletion of phase III to encourage maintenance of physical activity in phase IV. In addition, exercise consultation has the potential to help patients at all tran- sitions of CR, for example, from phase I to phase II. Applying exercise consultation to CR Is it feasible to incorporate the exercise consultation into current CR services? First,the consultations are relatively inexpensive in terms of time,resources and personnel. Exercise consultations last approximately 20 to 30 minutes and the support phone calls five to 10 minutes.
