It is said that in organic weakness the hand will hit the face arrhythmia drugs order 160mg diovan with visa, whereas patients with functional weakness avoid this consequence blood pressure 40 over 0 purchase generic diovan online. The term was invented in the nineteenth century (Hamilton) as an alternative to aphasia blood pressure chart by who order 40 mg diovan, since in many cases of the latter there is more than a loss of speech blood pressure normal range for adults buy generic diovan 40 mg, including impaired pantomime (apraxia) and in symbolizing the relationships of things. Hughlings Jackson approved of the term but feared it was too late to displace the word aphasia. Cross References Aphasia, Apraxia Asomatognosia Asomatognosia is a lack of regard for a part, or parts, of the body, most typically failure to acknowledge the existence of a hemiplegic left arm. Asomatognosia may be verbal (denial of limb ownership) or non-verbal (failure to dress or wash limb). All patients with asomatognosia have hemispatial neglect (usually left), hence this would seem to be a precondition for the development of aso matognosia; indeed, for some authorities asomatognosia is synonymous with personal neglect. Attribution of the neglected limb to another person is known as somatoparaphrenia. The neuroanatomical correlate of asomatognosia is damage to the right supramarginal gyrus and posterior corona radiata, most commonly due to a cerebrovascular event. The predilection of asomatognosia for the left side of the body may simply be a re ection of the aphasic problems associated with left sided lesions that might be expected to produce asomatognosia for the right side. Asomatognosia is related to anosognosia (unawareness or denial of ill ness) but the two are dissociable on clinical and experimental grounds. The term has no standardized de nition and hence may mean different things to different observers; it has also been used to describe a disorder characterized by inability to stand or walk despite nor mal leg strength when lying or sitting, believed to be psychogenic (although gait apraxia may have similar features). A transient inability to sit or stand despite normal limb strength may be seen after an acute thalamic lesion (thalamic astasia). Cross Reference Gait apraxia Astereognosis Astereognosis is the failure to recognize a familiar object, such as a key or a coin, palpated in the hand with the eyes closed, despite intact primary sensory modal ities. Description of qualities such as the size, shape, and texture of the object may be possible. There may be associated impairments of two-point discrim ination and graphaesthesia (cortical sensory syndrome). Astereognosis was said to be invariably present in the original description of the thalamic syndrome by Dejerine and Roussy. Some authorities recommend the terms stereoanaesthesia or stereohypaes thesia as more appropriate descriptors of this phenomenon, to emphasize that this may be a disorder of perception rather than a true agnosia (for a similar debate in the visual domain, see Dysmorphopsia). Cross References Agnosia; Dysmorphopsia; Graphaesthesia; Two-point discrimination Asterixis Asterixis is a sudden, brief, arrhythmic lapse of sustained posture due to involun tary interruption in muscle contraction. It is most easily demonstrated by observ ing the dorsi exed hands with arms outstretched. These features distinguish asterixis from tremor and myoclonus; the phenomenon has previously been described as negative myoclonus or neg ative tremor. Unilateral asterixis has been described in the context of stroke, contralateral to lesions of the midbrain (involving corticospinal bres, medial lemniscus), tha lamus (ventroposterolateral nucleus), primary motor cortex, and parietal lobe; and ipsilateral to lesions of the pons or medulla. Asynergia Asynergia or dyssynergia is lack or impairment of synergy of sequential muscular contraction in the performance of complex movements, such that they seem to become broken up into their constituent parts, so-called decomposition of move ment. Dyssynergy of speech may also occur, a phenomenon sometimes termed scan ning speech or scanning dysarthria. This is typically seen in cerebellar syndromes, most often those affecting the cerebellar hemispheres, and may coexist with other signs of cerebellar disease such as ataxia, dysmetria, and dysdiadochokinesia. Cross References Ataxia; Cerebellar syndromes; Dysarthria; Dysdiadochokinesia; Dysmetria; Scanning speech Ataxia Ataxia or dystaxia refers to a lack of coordination of voluntary motor acts, impairing their smooth performance. Ataxia is used most frequently to refer to a cerebellar problem, but sensory ataxia, optic ataxia, and frontal ataxia are also described, so it is probably best to qualify ataxia rather than to use the word in isolation. An International Cooperative Ataxia Rating Scale has been developed to assess the ef cacy of treatments for cerebellar ataxia. These bres run in the corticopontocerebellar tract, synapsing in the pons before passing through the middle cerebellar peduncle to the contralateral cerebellar hemisphere. Triple ataxia, the rare concurrence of cerebellar, sensory, and optic types of ataxia, may be associated with an alien limb phenomenon (sensory type). International Cooperative Ataxia Rating Scale for pharmacological assessment of the cerebellar syndrome. This syndrome is caused by lacunar (small deep) infarcts in the contralateral basis pons at the junction of the upper third and lower two-thirds. It may also be seen with infarcts in the contralateral thalamocapsular region, posterior limb of the internal capsule (anterior choroidal artery syndrome), red nucleus, and the paracentral region (anterior cerebral artery territory). Sensory loss is an indica tor of capsular involvement; pain in the absence of other sensory features is an indicator of thalamic involvement. Athetosis often coexists with the more owing, dance-like movements of chorea, in which case the movement dis order may be described as choreoathetosis. Athetoid-like move ments of the outstretched hands may also been seen in the presence of sensory ataxia (impaired proprioception) and are known as pseudoathetosis or pseudo choreoathetosis. Cross References Chorea, Choreoathetosis; Pseudoathetosis; Pseudochoreoathetosis Athymhormia Athym(h)ormia, also known as the robot syndrome, is a name given to a form of abulia or akinetic mutism in which there is loss of self-autoactivation. Clinically there is a marked discrepancy between heteroactivation, behaviour under the in uence of exogenous stimulation, which is normal or almost normal, and autoactivation. Left alone, patients are akinetic and mute, a state also known as loss of psychic self-activation or pure psychic akinesia. It is associated with bilat eral deep lesions of the frontal white matter or of the basal ganglia, especially the globus pallidus. Athymhormia is thus environment-dependent, patients nor malizing initiation and cognition when stimulated, an important differentiation from apathy and akinetic mutism. The term is often applied to wasted muscles, usually in the context of lower motor neurone pathology (in which case it may be synonymous with amyotrophy), but also with disuse. Atrophy develops more quickly after lower, as opposed to upper, motor neurone lesions. It may also be applied to other tissues, such as subcutaneous tissue (as in hemifacial atrophy). Atrophy may sometimes be remote from the affected part of the neuraxis, hence a false-localizing sign, for example, wasting of intrinsic hand muscles with foramen magnum lesions. Cross Reference Dementia Attention Attention is a distributed cognitive function, important for the operation of many other cognitive domains; the terms concentration, vigilance, and per sistence may be used synonymously with attention. It is generally accepted that attention is effortful, selective, and closely linked to intention. Impairment of attentional mechanisms may lead to distractability (with a resulting complaint of poor memory, perhaps better termed aprosexia), disori entation in time and place, perceptual problems, and behavioural problems. The neuroanatomical substrates of attention encompass the ascending retic ular activating system of the brainstem, the thalamus, and the prefrontal (mul timodal association) cerebral cortex (especially on the right).

Susan Roden, the secretary of the group, and to the editorial committee comprised of Drs. Gordon, who as chief editor of the interim and final full reports, collected, coordinated and edited the contributions of individual members and assured the quality of the document. The Working Group is thankful for important input received on several topics from many individuals outside the Group. Linda Hostelley for their thoughtful review of the entire manuscript and for their valuable suggestions, and to Mr. Available Bibliographic Databases Suitable for Identifying Reports of Adverse Drug Reactions. Examples of Acceptable and Unacceptable Company Clinical Evaluation Comments in Case Narratives. From the beginning, the Groups have been dedicated to focussing on the processes for detection and management of potential problems with drugs as quickly and efficiently as possible, especially in the post-approval environment. Working Group V hopes that its proposals on pragmatic approaches to some difficult dilemmas facing regulatory authorities and companies in carrying out their daily responsibilities will be endorsed and applied by all stakeholders. Specifically, we hope that the suggestions made in the following key areas will be widely implemented. Thus, we envision a world in which all who are engaged in pharmacov igilance will constantly work toward continuous learning, self-improvement, and sharing. All members have served less as representatives of any single organization or interest and more as motivated colleagues, with day-to-day responsibility in the drug safety field. All shared a commitment to think beyond their local practices even if such thinking were in disagreement with current rules and regulations, in order to optimize drug safety procedures, particularly in an international context. Gratifyingly, many of their recommendations have been incorporated into regulations, not only in the countries of the participating regulators, but elsewhere as well. All published by the Council for International Organizations of Medical Sciences, Geneva. The vision was that the primary recipient of a report, whether a regulator or industry would follow up a case, as needed, and enter it directly into a universally shared database. Another area deemed of high priority but outside the scope of this report, namely risk communication, was also identified and selected for parallel effort by an independent sub-group. With great affection, upon celebration of his twenty-five years of achievements and of his retirement at the close of 1999, we pay tribute to him through the present work. Finally, we wish to express our deep sense of loss and great respect for our colleague, Dr. Background Much progress has been made over the past several years in reducing unnecessary diversity in regulations and guidances among health authorities in the field of pharmacovigilance. As will become clear, these topics represent many obvious as well as subtle issues that affect different aspects of drug safety work. They influence how companies and regulators design their data base systems and their Standard Operating Procedures and they generally present difficulties in day to day working practices. A few topics involved some very complex and controversial issues on which consensus could not be reached with regard to recommending solutions. These and items which were not or could not be addressed might form the basis of future work. This has particular relevance to health information, among the more sensitive types of data, and certainly applies to adverse event reports, which often include data that directly identify the subject and/ or the reporter with name, address, national health number, or other overt identifiers. Although current practices throughout the pharmaceutical industry and by regulatory authorities reflect a commitment to protection of personal data, new laws in many countries necessitate some changes in personal-data handling practices. Increased rights for data subjects include notification on who is processing their data, for what purpose, and with whom the data may be shared, as well as the ability to access their own data and make corrections. Under appropriate circumstances, this may require enhance ment of the ordinary informed consent process for activities such as clinical trials. The use of secondary databases, so important to pharmacoepidemiol ogy and retrospective studies in general, may also be affected. There is no intention to cover this complicated topic here in more detail and those working in pharmacovigilance, and clinical research generally, should familiarize themselves with applicable data protection laws and regulations. For adverse event reporting, an identifiable patient or reporter relates to the existence of a real person that can be verified/validated in some way. Overview As a guide to the contents of this report, the following brief description of each of the topics and the rationale for their inclusion will aid the reader. Unless indicated otherwise in the specific topic Chapters, the proposed concepts and proposals apply to pre-marketing and marketing conditions for both prescription and non-prescription products, whether they be drugs, biologics or vaccines. The principles and recommendations presented here should apply to those products as well. They are handled differently from reports arising from clinical trials with regard to expedited and periodic reporting procedures. For example, by international convention, spontaneous reports are always considered to have an implied causal relationship to the subject drug(s). There are several influences complicating the classification and handling of spontaneous reports, for which some consensus and guidance would be helpful. As part of good pharmacovigilance practices and regulatory reporting requirements, companies monitor various types of literature for relevant safety information on their products. Other than the obvious sources, namely published prominent medical and scientific literature, what else should be reviewed among the thousands of journals and other published materials in many languages Who should be responsible for reporting the relevant information when there are multi-source, including generic, manufacturers The rapid and widespread growth of the electronic communication technology commonly referred to as the Internet and e-mail presents some difficult challenges in the context of drug safety monitoring and reporting. The technology might be regarded as just another medium for facile information exchange, albeit one with unprecedented global reach and speed. However, there are many new considerations for pharmacovigilance that need debate and resolution. Patients who have difficulty coping emotionally with a physical illness or who have unusual even bizarre presentations are too readily dismissed by the inexperienced physician as having psychogenic disorders blood pressure hypertension discount diovan 40 mg otc. It is not uncommon for patients with neurological disorders to develop psychogenic symptoms in addition to the organic disorder blood pressure 10060 cheap diovan 160mg, particularly at times of stress arrhythmia yahoo answers buy generic diovan 160 mg. Very few patients with psychogenic disorders are true malingerers and they deserve to be treated with kindness and compassion blood pressure chart blank buy diovan. Often the history, if the patient is willing to give it to you in full, is suggestive of a psychogenic disorder. Until recently, neurologists were reluctant to make a firm diagnosis of psychogenicity for fear that eventually an organic basis for the symptoms would emerge. As a result, many patients were subjected to endless rounds of investigations, confirming their own worst fears about the nature of their illness, nor were they provided with the support and understanding which their condition required. Fortunately, the diagnosis 110 Psychogenic disorders of a psychogenic disorder is now widely accepted and respectable. There may be emotive features such as exaggerated effort, sighing, groaning and gasping. Of course, all of these can happen in patients with a gait disturbance on an organic basis, but the difference is that in psychogenic gait there will be no relevant associated physical signs such as spasticity (increased tone and reflexes), clonus, rigidity, akinesia or intention tremor. As you watch, it may have a variable amplitude but also change its frequency, direction and distribution. Suggestibility may be also used to bring on a movement disorder that is paroxysmal and not present at the time of the evaluation. Also, restraining the shaking limb may result in an emergence of shaking in contralateral limb or in another body part. These and other distraction manoeuvres will often cause psychogenic tremor to change its pattern or frequency, or cease. Unfortunately, some organic tremors may also be affected by distraction, so reliance should not be placed on this test alone. All of us jump in response to a loud noise or an unexpected pain, perhaps from a pin jab. Psychogenic startle has to be distinguished from the rare hyperekplexia and stimulus-sensitive or reflex myoclonus. The pattern of recruitment when recorded neurophysiologically often occurs in an orderly sequence, consistent with the normal anatomical distribution, in organic myoclonus where as it is quite haphazard in psychogenic myoclonus. Also, when neurophysiological techniques are employed, latency from the stimulus (sudden loud sound or a visual threat) to the onset of muscle contraction is usually longer than 100 msec in psychogenic jerks whereas organic reflex myoclonus usually has a latency between 40 and 100 msec. Although organic dystonia is rarely painful, patients with psychogenic dystonia often complain of painful spasms. When examining a patient with psychogenic dystonia, one often encounters resistance against passive movement. It may follow a minor injury and may be accompanied by discoloration of the skin and trophic changes, typically seen with reflex sympathetic dystrophy, now referred to as complex regional pain syndrome. Severe flexion of the spine (camptocormia) was first described in soldiers coming out of trenches during the First World War, and found to be a feature of post-traumatic stress disorder. Features suggestive of this include: excessive effort (grimacing, panting and gasping) when asked to move the affected limb(s); periods of days or weeks when power returns to normal; absence of objective signs such as changes in tone and reflexes; improvement with suggestion. The key is that it does not conform to the anatomical boundaries of, say, a root or nerve. Periods of normality are reassuring and help to confirm the diagnosis of psychogenicity. Each eye appears to fail to abduct on either lateral gaze, producing markedly dysconjugate gaze with or without diplopia, accompanied by miosis (pupillary constriction). Although brainstem lesions can result in convergence spasm, this sign is often seen in the setting of psychogenic disorders. Here, the eyebrow on the affected side is lowered, unlike in true ptosis where it is usually elevated (in an attempt to raise the eyelid). One exception is hemifacial spasm in which the ipsilateral eyebrow is often elevated due to frontalis contraction. These include dystonia, chorea and truncal ataxia (due to a midline cerebellar lesion where there may be no other cerebellar signs). Lack of insight or denial of any stress prior to the onset of the symptoms is very frequent at the time of initial evaluation and the psychodynamic factors may not be apparent until subsequent interviews. The patient is unable to abduct the index finger on the right, and there is wasting of the first dorsal interosseous muscle. Wrist drop on the right, failure to abduct the fingers in the flexed posture, failure to contract brachioradialis on wrist flexion against resistance. The fingers flex when the radius is tapped, but there is no reflex contraction in brachioradialis. The patient gets into a tangle trying to put her jacket back on, having inadvertently pulled the left sleeve inside out. Diovan 160mg without prescription. Blood Pressure with Dr. Berry. |
