Chronic Diseases - Clinical Medicine Flashcards
What are chronic conditions?
- Chronic conditions are diseases lasting more than 3 months and some have no cure
- The disease would normally result in significant adjustment for the individual and increased contact with medical services
Provide 6 examples chronic diseases
- Alzherimer’s
- Arthritis
- Asthma
- Cancer
- MS
- Epilepsy
Describe the people involved in chronic disease management
- Practice nurses have a key role in primary care
- District nurses’ role is important for elderly and houseband
- GP in primary care may be main person responsible for others
- Pharamacists
- Specialist teams: consultant, specialist nurses
- Other health professionals: CPNs, counsellors, psychologists, psychiatrists
- Social servives, home care
- Voluntary agencies: self-help groups, disease groups, benefits advisors
- Occupational health dept at workplace
Describe the regular reviews regarding a patient’s condition that should be made including the disease, treatment and secondary prevention
This disease
- Check patient understanding
- Monitor disease progress
The treatment
- Check patient understanding
- Montor adherence, effectiveness, side effects, adverse effects
Secondary prevention
- Check patients understanding of risk of other conditions developing
- Assess/monitor/treat risk factors
What regular reviews should be made on a patient themselves who is suffering from a chronic disease
- Effects on feelings - sick role, self-esteem, stigma
- Effects on life e.g., relationshipps, work, finance, other acitivies, hosuing, mobility
- Effects on family/carers
Describe a doctor’s respone to chronic illness
- Curative medicine approach
- Sense of failure or feeling overwhelmed as many cannot be cured
- Perspective of palliative medicine
Chronic diseaes can co-exist. Give two reasons for this and provide an example for each reason
- May occur beacuse one disease directly causes another e.g., diabetes leads to renal damage
- May occur because both conditions share a common cause e.g., poor diet/secondary lifestyle increases risk of range of conditions e.g., diabetets and hypertension
a) Give 2 unmodifiable risk factors of chronic disease
b) Give 5 modifiable risk factors of chronic disease
a) Age and genetic (inherited) risk
b)
- Diet and excercise - act in party by causing obesity
- Pollution
- Smoking
- Alcohol consumption
- Social factors e.g., deprivation
what is chronic back pain?
Back pain that persists for more than three months
Low back pain is a major cause for long term sickness amongst workforces. Provide 6 examples of team members that may be involved in care of chronic back pain
- GP or nurse practitioner
- Physiotherapist
- Osteopathy or chiropractic practitioner
- Radiology service
- Orthopaedic surgeon
- Rheumatologist
Chronic disease follows several different courses with consequent differences in the reponse of the individual to that disease. Desrcibe the 3 possible trajectories and provide examples for each
- Short period of evident decline e.g.,
- Long term limitation with intermittent serious episodes - e.g., heart and lung cancer
- Prolonged dwindling - e.g., frailty and dementia
What is pain?
An unpleasant sensory and emotional experience associated with, or resembling that associated with actual or potential tissue damage
What is chronic primary pain?
Pain existing as a disea by itself and associated with emotional distress
What is nociceptive pain?
Pain arising from activation of nocieptors following tissue injury - A delta and C-fibre terminals
What is neuropathic pain?
Pain arising from disease or damage to the nervous system
Pain signifies a threat to body integrity. Pain is interoceptive rather than exteroceptive. What do these two terms mean?
Interoceptive = sensing internal body states
Exteroceptive = sensing external environment
Describe the role of the limbic system in chronic pathological pain
Enhanced activation of the limbic system amplifies the negative threat of your interoceptive state which is a key factor that drives chronic pathological pain
Nociception is what drives cognition of something unpleasant happening which is happening in the context of the way your suffering is manifested and the way you behave and how you interact with the social environment. A consideration of all these is known as?
Biopsychosocial pain management
What factors are involved in the biopsychosocial pain management?
- Nociception
- Cognititon (pain)
- Affective (suffering)
- Illness (pain behaviour)
- Social environment
How well do drugs work in pathological pain?
- As studies have gotten bigger and better, the number needed to treat (NNT) have increased across all classes off drug, in chronic pain or neuropathic pain
- NNT is still only between 4 and 10 so only a minority of patients are going to be very responsive to medication and a lot of patients will not respond at all
If drugs aren’t the answer, how else can we modify distress and emotion? Provide 4 examples

What are criticisms of fibromyalgia diagnosis
- Criteria are a compromise
- There is no gold standard pathology
- Not grounded in any clear pathological process
- Fibromyalgia may just be one end of the spectrum
Describe the epidemiology of fibromyalgia
- Prevalence: fibromyalgia 1-10% and chronic widespread pain 10-20%
- F:M = 3:1 = three times more common in women than men
- Rises with age to a maximum in 60s
- Disability level comparable to RhA
What are the clinical descriptions that patient use to describe fibromyalgia
- ‘It hurts all over’
- May ahvea focus, but shifts
- Burning, radiating, gnawing
- Moderate or severe
- Worse than that of RhA
- Cold damp weather
- Exhibit hyperalgesia (an increased sensitivity to feeling pain and an extreme response to pain) and allodynia (neuropathic pain due to a stimulus that does not normally provoke pain e.g., light feather touch, cold temperatures)
What will you find on examination of patient with fibromyalgia
- Tender points are the only reliable physical finding
- No muscle wasting
- No synovial inflammation
- No other abnormalities
What will you find on investigation of a patient suffering from fibromyalgia
Normal
- No inflammatory markers
- No metabolic or endocrine abnormality
- Muscle enzymes and electromyography (EMG normal)
What diseases overlap with fibromyalgia?

- Post-traumatic syndrome
What disease can fibromyalgia present in?
- Inflammatory rheumatic disease - 30%

Describe 8 causes of fibromyalgia
- Infection - widespread pain follows infectious mononucleosis n 20%, 20% have persistent symptoms after Lyme
- Trauma - associations with leg fracture, neck fracture, hypermobility
- Genetics - familial clustering, HLA associations
- Muscle abnormality - intrinsic muscle abnormalities have been detected (but likely to be secondary to inactivity or to pain)
- Psychological abnormality - greater psychological symptoms, greater prevalence of depression in family, healthcare seeking behaviours
- Sleep abnormality - slow wave disruptions triggers FM, EEG patterns reported
- Neuroendocrine - reduced growth hormone, prolactin, 5HT, CRH response to stress
- CNS autonomic sensitisation - altered pain threshold on physiological testing at tender points and other sites, increased heart rate variability, CSF substance P levels (neurotransmitters) increases causing increased sensitivity of nerves to pain or heighten awareness to pain, brain regional blood flow abnormalities in areas related to pain processing and abnormal termporal summation of pain
Describe the managment of fibromyalgia
Drug treatment
- Anti-inflammatory (however no better than a placebo)
- Antidepressants - low dose tricyclic antidepressants, amitriptyline effective in reducing pain, serotonin reuptake inhibitors (short term effect)
- Opiates - tramadol, ketamine
Non-drug treatment
- Education
- Excercise
- Physical therapy
- Behavioural
- Cognitive therapy
- Mediation
- Biofeedback
- Stress management
- Hypnotherapy
- Acupuncture
- Homeopathy (A “treatment” based on the use of highly diluted substances, which practitioners claim can cause the body to heal itself)
Describe the prognosis of fibromyalgia
- Conflicting
- Tertiary centres show little change over a decade
- Better outcome in community studies, where (at best) 25% remit at 2 years
- Predicting better outcome: young age, lower pain score
According to Parsons’ ‘Sick role’, someone who is ill gains rights and responsibilities. What are the rights and responsibilties of the ‘sick role’
Rights
- The sick are not obliged to perform their normal social roles
- The sick are not considered responsible for their own state/being ‘in the sick role’
Responsibilites
- The sick are obliged to want to get well as soon as possible
- The sick are obliged to consult and cooperate with medical experts
What are the main functions of the ‘sick role’?
- To control illness
- Reduce the disruptive effects on the social systems by returning the ill to good health as quickly as possible
Why may patients find the sick role appealing?
- Devolves them of personal responsibilty for the cause of their illness
- Legitamises avoidance of the unappealing aspects of everyday life - work, chores, being pleasant to people, being active, eating healthily
- Suggests that illness should be cured, rather than having to live with the symptoms
- Suggests that it’s the doctor’s role to cure them
What are treatment/actions for chronic pain and co-morbidies e.g., depression
- Explanation + guidance about the factors worsening pain
