Q

Chronic diseaes can co-exist. Give two reasons for this and provide an example for each reason

A
  1. May occur beacuse one disease directly causes another e.g., diabetes leads to renal damage
  2. 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

Q

Pain signifies a threat to body integrity. Pain is interoceptive rather than exteroceptive. What do these two terms mean?

Q

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

Q

How well do drugs work in pathological pain?

A
  • 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

A
  • ‘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)
31
Q

What will you find on examination of patient with fibromyalgia

A
  • Tender points are the only reliable physical finding
  • No muscle wasting
  • No synovial inflammation
  • No other abnormalities
32
Q

What will you find on investigation of a patient suffering from fibromyalgia

A

Normal

  • No inflammatory markers
  • No metabolic or endocrine abnormality
  • Muscle enzymes and electromyography (EMG normal)
33
Q

What diseases overlap with fibromyalgia?

A
  • Chronic fatigue syndrome
  • Myofascial pain syndrome - pressure on sensitive points in your muscles, causingpain in muscles and unrelated partsof body e.g., whiplash, writer’s cramp, telegraphists cramp, repetitive strain
  • Irritable bowel syndrome
  • Migraine
  • Irriatable bladder
  • Post-traumatic syndrome
34
Q

What disease can fibromyalgia present in?

A
  • Inflammatory rheumatic disease - 30%
  • Inflammatory myositis and myopathies
  • Hypothyroidism
  • Multiple sclerosis
35
Q

Describe 8 causes of fibromyalgia

A
  1. Infection - widespread pain follows infectious mononucleosis n 20%, 20% have persistent symptoms after Lyme
  2. Trauma - associations with leg fracture, neck fracture, hypermobility
  3. Genetics - familial clustering, HLA associations
  4. Muscle abnormality - intrinsic muscle abnormalities have been detected (but likely to be secondary to inactivity or to pain)
  5. Psychological abnormality - greater psychological symptoms, greater prevalence of depression in family, healthcare seeking behaviours
  6. Sleep abnormality - slow wave disruptions triggers FM, EEG patterns reported
  7. Neuroendocrine - reduced growth hormone, prolactin, 5HT, CRH response to stress
  8. 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
36
Q

Describe the managment of fibromyalgia

A

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)

37
Q

Describe the prognosis of fibromyalgia

A
  • 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
38
Q

According to Parsons’ ‘Sick role’, someone who is ill gains rights and responsibilities. What are the rights and responsibilties of the ‘sick role’

A

Rights

  1. The sick are not obliged to perform their normal social roles
  2. The sick are not considered responsible for their own state/being ‘in the sick role’

Responsibilites

39
Q

What are the main functions of the ‘sick role’?

40
Q

Why may patients find the sick role appealing?

A
  • 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
