I started being bothered by the limp in the summer but didn’t go to the doctor until that fall. I would go overseas for two, three, sometimes even four weeks at a time, which meant I was carrying damned near everything I own and running through airports with this massive bag banging against my knee. So I never really thought much about it except that this one didn’t go away. I came in for a variety of torture tests, which were essentially measuring the nerves’ response to being stabbed and jolted. Progres- sively, I had to have braces on one leg and then both legs to help me stand up. Shortly thereafter I got a wheelchair for outside and a tricycle walker for home. Increasing weakness in my legs that has taken me from limping to not being able to walk at all. Lester Goodall, in his mid fifties, had long-standing diabetes requiring insulin. A manager in a Fortune 500 company, Lester’s recreational passion was throwing darts in leagues organized at local pubs. I would pick up my darts and try to get into the right position holding the darts, but I couldn’t. Then I’d stand on the line like you normally do, and the 32 / Sensations of Walking next step lose my balance. I attributed this to my dia- betes acting up, my blood sugar being high because I wasn’t control- ling it like I’m supposed to. It was like someone had taken the contrast on a TV and turned it up as bright as they could, and I couldn’t see the contrasts. So they put me through all of these tests, a vestibular test for the balance, this test, that test. Goodall’s MS started with two characteristic symptoms of the dis- ease—imbalance and difficulties with vision. This combination is especially troubling since vision problems compound the risk of falls. Goodall’s im- balance often leads people to think he is drunk:“It always appeared that I was inebriated and losing my balance. I didn’t know myself what was wrong back in those days, so I just figured, hey! I know there’s times when I’m walking and people look at me and think this man had too much to drink. Instead of planting their feet firmly where they used to, striding purpose- fully forward, their legs splay outward and their steps veer erratically. Often these changes reflect the nervous system’s attempt to restore or maintain balance in the face of neurologic deficits. The characteristic gait of a person with MS is described as “broad based”—feet planted far apart, trying to keep the walker erect. In contrast, diabetes mellitus can lead to “peripheral neuropathy,” a nerve problem that diminishes sensations in the lower extremities (toes, feet, and legs). That is one reason why periodic foot examinations are recommended for persons with diabetes, who may not feel injuries or sore spots, leaving wounds inadequately treated. Arnis Balodis had peripheral neuropathy from decades with diabetes and had had both legs amputated because of encroach- ing gangrene. Using mirrors, he carefully checked the stumps of his legs where they fit into his prostheses. Especially with illnesses that com- promise cognitive function or the ability to communicate, walking prob- Sensations of Walking / 33 lems may appear relatively manageable, particularly if they can be compen- sated for with mobility aids. An example is Parkinson’s disease, first de- scribed by James Parkinson over 180 years ago. Affecting more than one million people in North America, its cause is unknown, although genetics and aging play a role (Lang and Lozano 1998a, 1998b).

Tachycardia Certain adverse signs in bradycardia dictate the need for intervention: Tachyarrhythmias are conventionally divided into those arising ● Systolic blood pressure less than 90mmHg within the ventricular myocardium (ventricular tachycardias) or ● Ventricular rate less than 40 beats/min those arising above purchase 5 mg compazine fast delivery, or sometimes within buy compazine 5mg without prescription, the AV junction ● Presence of ventricular arrhythmias (supraventricular tachycardias). This has obvious merit requiring treatment with regard to treatment and prognosis, but considerable ● Presence of heart failure diagnostic difficulties may be encountered when relating the electrocardiographic appearance to the underlying mechanism of an arrhythmia. Ventricular tachycardia characteristically has a broad width QRS complex, but some rare tachycardias arising below the 21 ABC of Resuscitation AV junction may have a complex width within the normal range. Supraventricular tachycardia characteristically has a narrow QRS, but it may be widened when conduction is abnormal—for example, in the presence of bundle branch block. The guidelines make no assumption that the mechanism of tachycardia has been accurately defined and the recommendations for treatment are based on a simple Broad complex tachycardia: treatment will depend on the presence of electrocardiogram classification into narrow or broad complex adverse signs tachycardia. In the context of peri-arrest arrhythmia, it is always safest to assume that a broad complex tachycardia is ventricular in origin. Broad complex tachycardia Little harm results if supraventricular tachycardia is treated as Treat broad complex tachycardia as sustained ventricular tachycardia** a ventricular arrhythmia; however, the converse error may have serious consequences. The first question that determines management is whether a palpable pulse is present. Pulseless ventricular tachycardia If not already done, give oxygen and establish intravenous (i. Yes If a pulse is present oxygen should be administered and Adverse signs? No - Systolic BP <90 mmHg Yes intravenous access established if this has not already been done. The algorithm describes four such signs: help ● A systolic blood pressure less than 90mmHg. If potassium known to be low Synchronised DC shock* see panel 100J : 200J : 360J ● The presence of chest pain. If the plasma Seek expert Further cardioversion potassium concentration is known to be less than 3. If cardioversion is unsuccessful it is appropriate to further amiodarone 150 mg i. If these measures are unsuccessful additional doses of Doses throughout are based on an adult of average body weight amiodarone or alternative anti-arrhythmic drugs may be * Note 1: DC shock always given under sedation/general anaesthesia. Overdrive ** Note 2: For paroxysms of torsades de pointes, use magnesium as above or overdrive pacing (expert help strongly recommended). London: Resuscitation Council (UK), 2000 If the serum potassium concentration is known to be low an infusion of potassium and magnesium should be given. If the potassium concentration is unknown it must be measured immediately. Amiodarone is again recommended as the drug of first choice to stop the tachycardia; lignocaine (lidocaine) remains an alternative. With most patients there should be time to consult expert help to advise about management. Synchronised cardioversion should preferably be attempted after Overdrive pacing is a technique whereby the allowing one hour for the amiodarone infusion to take effect. The tachycardia amiodarone should be given, allowing time for the drug’s may be abolished with a return of normal powerful anti-arrhythmic action before cardioversion is repeated. Narrow complex tachycardia A narrow complex tachycardia is virtually always supraventricular in origin—that is, the activating impulse of the tachycardia passes through the AV node. Supraventricular 22 Management of peri-arrest arrhythmias tachycardias are, in general, less dangerous than those of ventricular origin and only rarely occur after the successful treatment of ventricular tachyarrhythmias. Nevertheless, they are a recognised trigger for the development of ventricular fibrillation in vulnerable patients. If the patient is pulseless in association with a narrow complex tachycardia, then electrical cardioversion should be Narrow complex tachycardia attempted immediately. As in the treatment of any serious rhythm disturbance, oxygen should be administered and intravenous access established. At this stage it is important to exclude the presence of atrial fibrillation. This is a common arrhythmia occurring before cardiac arrest and often in the post-resuscitation period. In atrial fibrillation the ventricular response is irregular, unlike the regular ventricular pattern seen with other rhythms that arise above the AV junction.

There are few data available on the use of intrathecal baclofen in primary dystonia and the use of this therapy in primary dystonia is controversial purchase compazine 5mg on line. Several other medications may be effective in a minority of children with primary dystonia generic compazine 5mg without prescription. Botulinum toxin injections are highly effective in focal and segmental dystonias due to the limited number of muscles involved. It plays a smaller role in treatment of generalized dystonia because of the large number of involved muscles. However, it can be quite helpful in reducing symptoms when isolated problematic muscle groups are targeted. Nonpharmacologic Treatment Promising neurosurgical treatments of dystonia include thalamotomy, pallidotomy, and deep brain stimulation (DBS) of the globus pallidus pars interna. Thalamotomy was the most frequently performed ablative procedure in the past. However, when performed bilaterally, there is a high incidence of dysarthria and dysphagia. More recently, pallidotomy has been pre- ferred to thalamotomy because of the lower morbidity. Direct comparison has not been performed, but data suggest that pallidotomy is more effective than thalomot- omy in DYT-1 dystonia. Most recently, pallidal DBS has been used to treat DYT1 dystonia with promising early results. The effects of DBS are similar to those of pallidotomy, but DBS is programmable and does not involve a destructive lesion. Physical and occupation therapy can be helpful in maximizing the function of individuals with primary generalized dystonia. Secondary Dystonia Some secondary dystonias may also respond to levodopa and therefore, a trial of levodopa is recommended for any child in whom dystonia is a prominent component Dystonia 143 of their neurologic syndrome. For example, if the cause is a medication or other toxin, the best course is to eliminate that agent. If available, specific treat- ment for the underlying metabolic disturbance should be employed. In cases where there is no known primary treatment or when symptoms persist despite treatment of the underlying cause, symptomatic treatment can be employed. There are relatively few data on the efficacy of various agents in the treatment of secondary dystonia. The medications described above for primary dystonia may be effective in secondary dystonias. Empirical treatment with carbidopa=levodopa, trihexyphenidyl, baclofen, carbamazepine, or a combination should be considered. In the case of tardive dystonia, dopamine depletors such as reserpine or tetra- benazine can be effective. Reserpine should be started at a dose of 20 mg=kg daily and increased gradually until benefit is achieved or side effects occur. The most common side effects are sedation, depression, orthostatic hypotension, and parkinsonism. Tertrabenazine is also effect in tardive dystonia, but is not available in the United States. The dose should be increased gradually until there is benefit or side effects occur. The effective maintenance dose varies widely from 25 to 200 mg per day divided three times daily. Perhaps the most common secondary dystonia is the acute dystonia reaction that typically occurs in response to a dopamine antagonist. Anticholinergic medica- tions are the most effective; benztropine and diphenhydramine are the most com- monly used agents to treat acute dystonia reactions. After occurrence of an acute dystonia reaction, re-exposure to a dopamine antagonist should be avoided if possible.
