GP part 2 Flashcards
what is irritable bowel syndrome
it is recurrent abdominal pain or discomfort which is associated with a change in stool frequency or form
the pain or discomfort may be relieved by defecation
what are symptoms of IBS
intestinal discomfort - pain, bloating, worse after eating, improved by opening bowels
bowel habit abnormalities - fluctuating
stool abnormalities - diarrhoea, constipation, passing mucus
what can IBS symptoms often be triggered or worsened by
Anxiety
Depression
Stress
Sleep disturbance
Illness
Medications
Certain foods
Caffeine
Alcohol
what are risk factors for IBS
physical or sexual abuse
PTSD
age <50
female sex
previous enteric infection
family history
family and job stress
how do you diagnose IBS
thorough history and examination to exclude red flags or any other pathology
FBC - anaemia
inflammatory markers
coeliac serology
faecal calprotectin
CA125 for ovarian cancer
what are the NICE clinical guidelines for a diagnosis of IBS
differentials need to be excluded and the patient should have at least 6 months of abdominal pain or discomfort with at least one of:
- pain or discomfort relieved by opening the bowels
- bowel habit abnormalities
- stool abnormalities
for a diagnosis the patients also require at least two of:
- straining, an urgent need to open bowels or incomplete emptying
- bloating
- worse after eating
- passing mucus
what lifestyle advice is given to patients who are diagnosed with IBS
drink enough fluids
regular small meals
adjusting fibre intake according to symptoms
limit caffeine, alcohol and fatty foods
low FODMAP diet, guided by dietician
probiotic supplements may be considered over the counter
reduce stress where possible
regular exercise
how is IBS treated
- first line is lifestyle management
- medications depend on symptoms - loperamide for diarrhoea, bilk forming laxatives for constipation, antispasmodics for cramps (mebeverine, alverine, hyoscine butylbromide)
- Linaclotide is a specialist secretor drug for constipation in IBS when first line laxatives are inadequate
- where symptoms remain uncontrolled think about other options: SSRI, low dose tricyclic antidepressants, CBT and specialist referral
what is a soft tissue injury
this is damage to muscles tendons and ligaments which may lead to pain, swelling and restricted mobility
what are types of soft tissue injury
sprains: stretching or tearing of ligaments
strains: muscle or tendon damage often occurring to the hamstring
contusions: bruises resulting from blunt force trauma that squashes muscle fibres underneath the skin without breaking the skin barrier
tendinitis: irritation or inflammation in a tenon that occurs due to overuse
bursitis: inflammation and swelling in the bursae
what are symptoms of a sprain
swelling
bruising
pain
inflammation
limited range of motion
what are symptoms of a strain
pain
muscle spasms and weakness
swelling
inflammation
what are symptoms of a contusion
pain and skin discolouration
what are symptoms of tendinitis
swelling
pain that worsens during activity
what are symptoms of bursitis
pain
swelling
what are causes of soft tissue injury
trauma - sudden impact or forceful movements can lead to soft tissue injury which might occur due to a fall, slip or sharp change in direction
overuse - repetitive movements or excessive strain on a particular muscle or joint
overloading - sudden increase in exercise intensity
how is soft tissue injury diagnosed
clinical history and examination
Xray
MRI
how are soft tissue injuries treated
rest, ice, compression and elevation
medications - analgesia
physical therapy
bracing or splinting
torn muscles, tendons, or ligaments may need surgery depending on how much of the tendon has torn and how severe it is
what is the classification of sprains
graded on severity
Grade 1: slight stretching and some damage to the fibres of the ligament
grade 2: partial tearing of the ligament. there is abnormal looseness in the joint when it is moved in certain ways
grade 3: complete tear of the ligament. may cause significant instability
what is lyme disease
it is an infection transmitted to humans following a bite from an infected tick
what causes lyme disease
a group of bacteria - Borrelia burgdoferis which is a spiral shaped bacteria
what are risk factors for Lyme disease
occupational and recreational exposure to woodland and fields
increased duration of tick attachment (over 36-48 hours)
what are complications of Lyme disease
severe neurological symptoms - chronic meningitis, encephalomyelitis, radiculopathies, peripheral neuropathy
facial palsy
lyme arthritis
persisting non specific symptoms such as fatigue, aches and pains, cognitive difficulties
How is Lyme disease diagnosed
clinical diagnosis of lyme disease in people with erythema migrans:
- spreading erythema with well defined edges
- round or oval shape
- red/purple in colour
- bulls eye appearance
in those without erythema migrans clinical presentation and laboratory testing will guide diagnosis
