Primary Care Advice/Information 2017 Patients with Frailty Will Be At Primary Care Advice/Information 2017 Patients with Frailty will be at increased risk of falling. Nice Quality Standard Updated 2017 Quality statement Older people are asked about falls when they have routine assessments and reviews with health and social care practitioners, and if they present at hospital. [new 2017] Rationale A history of falls in the past year is the single most important risk factor for falls and is a predictor of further falls. Health and social care practitioners have regular contact with older people across a wide range of settings, including in people's homes. By asking questions in routine assessments and reviews about falls and their context, health and social care practitioners can identify older people who may be at risk of falling. If there is concern that a person is at risk of falling, they can be referred to, or advised to see, a healthcare professional or service to further assess their risk. Multifactorial fall risk assessment History Of Falling / Medicines / Dizziness History of falls: detailed description of the circumstances of the fall, frequency, symptoms at the time of the fall, injuries, other consequences, recall of events by witness. Medication review: all prescribed and OTC medications. History of relevant risk factors: acute or chronic medical problems (osteoporosis, urinary incontinence, cardiovascular disease). Physical examination - Walking and Balance / Feet Footwear / Vision / Hearing Assess gait, balance, and mobility and lower extremity joint function. Neurological function: cognition, lower extremity peripheral nerves, proprioception, reflexes, tests of cortical, extrapyramidal and cerebellar function. Muscle strength. Cardiovascular: heart rate, rhythm, pulse, BP checks postural blood pressures. Visual acuity. Examination of feet and footwear. Functional assessment and confidence Activities of daily living including use of mobility aids. Individual’s perceived functional ability and fear related to falling. Environmental assessment Including home safety. For those people who you think need more support, and to help you in managing those assessed at being at risk: For further information on countywide falls prevention http://www3.northamptonshire.gov.uk/councilservices/health/preventing- falls/Pages/default.aspx For prevention of falls and maintaining independence For those patients with reduced strength and balance consider an OTAGO exercise programme https://www.northamptonshiresport.org/otago-exercise-programme If you need to refer your patient for additional community healthcare see below for further information: For those patients that don’t need an immediate response, consider referral to Northamptonshire NHS Falls Prevention Service. It is ideally for those with a history of falls in the last 12 months and at risk of further falls. The team is made up of registered nurses, physiotherapist’s occupational therapists and a falls assistant with access to consultants and podiatry. The service is available countywide and operates Monday - Friday The service aim is to reduce the possibility of recurrence of falls and or minimise the risk of future injury fracture. You can access the referral form here https://www.nhft.nhs.uk/falls For urgent support For those patients who need district nursing/intermediate immediate assessment and support call the single point of access 0300770002 options 1 Further Reading/Article of interest “GPs' role in management of falls in the elderly”. By Dr Mark Jopling on the 10 November 2015: GP On-line http://www.gponline.com/falls-older-people/elderly-care/rehabilitation-falls/article/1372101 Falls are a common problem in the elderly and for busy GPs there are multiple challenges: managing the immediate injuries, trying to establish the cause (or causes) of a fall, remedying these causes and limiting the harm patients will come to if they do fall. Why do elderly people fall? Diseases of the eyes, ears, brain, heart, peripheral nerves, muscles and joints can all contribute to falls. There are also normal age-related changes, such as increased sway, a slower gait with smaller steps, reduction in muscle strength and slower reactions that increase the falls risk. Trip hazards should also be considered. There will often be multiple contributing factors. An elderly patient who falls is more likely to sustain more severe injuries, and injuries that take longer to heal. Social isolation can result in a long lie with the attendant risks of hypothermia, dehydration, blood loss, rhabdomyolysis and pressure sores. Loss of confidence after a fall can lead to a premature loss of independence. The history may reveal whether the faller blacked out (suggesting syncope, a seizure or a transient ischaemic attack [TIA]) or whether they tripped (suggesting a balance or gait problem or possibly just the presence of a trip hazard). A vague or absent history may indicate that dementia or delirium resulted in poor decision-making leading to the fall. Loss of consciousness Syncope, where there is loss of consciousness due to reduced cerebral blood flow, can be caused by: Vasovagal syncope (a faint) Cough or micturition syncope Orthostatic hypotension, which can be due to autonomic failure (such as in diabetes) or a medication side-effect. Anaemia, dehydration and infection can contribute to this. Carotid sinus hypersensitivity - shaving can be a trigger Arrhythmia, which may be heralded by palpitations Structural heart disease such as aortic stenosis or hypertrophic obstructive cardiomyopathy Seizures may have a metabolic cause such as hypoglycaemia, hypocalcaemia, hyponatraemia or alcohol withdrawal. Other causes are epilepsy, structural brain disease, subdural haematoma and CNS infections. TIAs are a rare cause of loss of consciousness. Tripping over Vision, the vestibular system and proprioception all contribute to balance. Failing eyesight or unworn, damaged or out of date glasses may contribute to a fall. Common causes of vertigo are benign paroxysmal positional vertigo (BPPV), vestibular neuronitis and migraine. The elderly can be more sensitive to the extrapyramidal side-effects of drugs such as prochlorperazine, so alternative treatments such as vestibular rehabilitation exercises or the Epley manoeuvre (for BPPV) may be more appropriate. Proprioception will be affected by joint degeneration and also peripheral neuropathy. Proprioceptive fibres run in the dorsal column, which can be damaged by B12 deficiency or alcoholism, leading to a wide-based, high- stepping gait. Neurological, muscle and joint diseases will affect gait. Parkinson’s disease causes postural instability. The classical triad of bradykinesia, rigidity and tremor may be present. Reduced arm swing, shuffling gait and slow turning are also clues to this diagnosis. Chronic cerebrovascular disease can cause the high stepping gait seen in `marche a petit pas’. Strokes may leave survivors with a hemiplegic gait. There are also more rare CNS diseases to consider such as normal pressure hydrocephalus with a lurching gait. Cerebellar disease will cause marked ataxia and unsteadiness on standing. Proximal myopathy due to osteomalacia or steroid use will cause a waddling gait and difficulty standing. Arthritis of the lower limb joints can cause an antalgic, unsteady gait. Mononeuropathies such as a peroneal nerve palsy causing foot drop, can increase the falls risk. Decision making Dementia or delirium can impair higher cerebral functions, which will affect the ability to compensate for mobility limitations and to make sensible decisions to avoid trip hazards. Drugs and alcohol There is an established link between polypharmacy and falls, so any medications should be scrutinized. Anticholinergic medication (such as those acting on the bladder), benzodiazepines and opiates can cause confusion in the elderly. Parkinson’s disease medication, tricyclic antidepressants, antipsychotics, diuretics, alpha-blockers, beta-blockers (even in eye drops1) and antiangina drugs are some of the medications that cause orthostatic hypotension. In old age even BP at the low end of normal may be too low and the target BP should be tailored accordingly. Steroids can lead to proximal myopathy as well as increasing the risk of fractures due to osteoporosis. Antidysrhythmics, rate-limiting calcium-channel blockers, beta-blockers and the anticholinesterase inhibitors used in dementia can all cause bradycardia leading to syncope. Antipsychotics and some vestibular sedative drugs can have extrapyramidal side-effects as well as causing sedation. SSRIs increase the risk of falls although the mechanisms are unclear. Alcohol intoxication may be the cause of a fall. The Royal College of Psychiatrists estimates that 1 in 5 older men and 1 in 10 older women are drinking a harmful amount.2 Assessing a frequent faller In a short GP consultation the examination has to be guided by the history. Where there has been loss of consciousness without a seizure, more emphasis should be given to cardiovascular examination including sitting and standing BP. In trips, more time should be spent observing the patient rising from sitting, walking and turning. Consider the value of the Romberg's test to assess proprioception. A simple corrected visual acuity test may be illuminating. Blood tests may reveal acute, reversible causes of falls or delirium. Hypocalcaemia, thyroid dysfunction or B12 deficiency can affect both cognition and mobility. NICE guidelines on the assessment and prevention of falls in older people stress

SECTION TWO Diagnostic Algorithm for Neurological Symptoms Symptoms involving the brain and the conditions that may be responsible SECTION THREE Neurological Conditions The symptoms, signs, investigation and treatment of medical conditions that may cause neurological symptoms. Appendices Mini-Mental Test Glasgow Coma Scale 2 A RATIONALE FOR THE BRAIN INTRODUCTION This book is designed for both the medical student and the doctor who is not a specialist in neurology. It will take the user through a logical rationale in order to diagnose, and then treat, virtually every neurological condition likely to be encountered outside a specialist practice. There are two ways to reach a diagnosis, using the chart in Section One, or the Diagnostic Algorithms in Section Two. In Section One, the chart will guide the user through headcahe symptoms to a selection of possible diagnoses. In Section Two the algorithms will indicate the diagnoses possible with a variety of neurological presenting symptoms. Once a diagnosis has, or number of differential diagnoses have been made, a detailed explanation of the various diagnoses can be found in the largest part of the book, Section Three. This has been written in a style that should be easy to understand by even junior medical students, with technical terms explained in each monograph, but should still be useful to the non-specialist doctor.

Up-to-date rehabilitation in Parkinson’s patients. Chula Med J 2010 Mar - Apr; 54(2): 101 - 10 Parkinson’s disease is a degenerative brain disease. The dopamine producing cells in substantia nigra of basal ganglia are progressively degenerate. This causes patients unable to control their movements. Symptoms usually show up with bradykinesia, or slowness of movement and one or more of three following symptoms: (1) tremor, or trembling in hands, arms, legs, jaw, and face, (2) rigidity, or stiffness of limbs and trunk (3) postural instability. In addition, abnormal autonomic nervous system, pain sensation, swallowing, bowel and bladder, sexual, emotion can present. At present, research and clinical evidences reveal that rehabilitation treatment can help the patients improve walking and movement abilities, have better balance, decrease fall risk, increase activities of daily living, and improve quality of life.

  • Medical Management of Parkinson's Disease
    3 Differential Diagnosis of Parkinsonism and Tremor Dr D Grosset Consultant Neurologist and Honorary Professor, Institute of Neurological Sciences, Queen Elizabeth University Hospital, Glasgow When Do Symptoms Develop? In PD, symptoms develop after the reserve capacity of dopaminergic neurones is exhausted. 18F- fluorodopa PET studies suggest that this probably occurs after at least 50% of dopaminergic neurones have degenerated, lower than previous estimates of 60 to 80%. However, enhanced synthesis of dopamine in surviving neurones (upregulation of striatal dopa decarboxylase activity) and increased dopaminergic stimulation of the striatum may underestimate the true proportion of cell loss. Symptoms may be present for some time (occasionally years) before the diagnosis is made, particularly in younger patients. Abnormalities in pre-synaptic dopamine turnover or dopamine transporter levels are detectable on functional imaging. Patients lose their sense of smell in the pre-clinical phase of PD. Olfactory dysfunction is found in 70- 80% of PD patients and is therefore as common as tremor, but loss of sense of smell occurs with aging and most hyposmic people do not get PD: Olfactory dysfunction also occurs in dementia with Lewy bodies Olfaction remains normal in PSP, corticobasal degeneration and vascular parkinsonism In MSA, spinocerebellar syndromes and essential tremor, any olfactory disturbance is mild Olfactory loss is usually not volunteered by the patient, who may only realise it once asked or with testing Olfactory loss tends not to occur in one of the genetic types of PD (Parkin). A higher rate of PD is reported in patients with essential tremor, and in families with essential tremor, but quantifying the relationship is difficult: Functional imaging studies suggests two separate entities As essential tremor is relatively common, is it inevitable that some patients with essential tremor will later develop PD Rarely, familial essential tremor occurs in conjunction with familial PD A subset of patients present temporally with ET and PD.

    Carter’s Medical Miscellany Carter’s MEDICAL MISCELLANY Dr. Warwick Carter MB.BS., FRACGP, FAMA Miscellany - noun - Separate articles or studies on a subject, or compositions of various kinds, collected into one volume. A literary work or production containing miscellaneous pieces on various subjects. (OED) 1 Carter’s Medical Miscellany These egregiously piquant peccadilloes of allopathic and homeopathic epistemology offer some chthonic edification extra mural to the canonical modes of the medical quidnunc. They are of inestimable significance to the virtuosity and animus of the therapist. These profoundly sagacious enunciations have been serendipitously gleaned from a wide amplitude of unerringly reliable provenances including my therial janizzaries. 2 Carter’s Medical Miscellany INTRODUCTION Doctors encounter some extraordinary and unusual facts during their training and careers, some of which are totally useless to the practice of medicine, but never the less interesting. This is a collection of just such information. This is not a dictionary, guide book, encyclopaedia or vademecum, just a miscellany of fascinating facts gleaned from a more than 30 year career in medicine, and the research necessary to write twenty other books that cover everything from postgraduate pathology texts to simple question and answer collections for lay people. In no way can the veracity of the facts within be vouched for, but to the best of my limited knowledge, they are true. As a result, no action should be taken on the basis of this information unless a doctor’s opinion is sought. This collection is designed primarily to intrigue, secondly to entertain, and rarely to educate. Please enjoy.
