71
Bishop Score:
Interpretation of Bishop score:
The Bishop Score-
The Bishop score is used to assess whether a patient is likely be a good candidate for an induction of labour.
Usually a score of 9 or more means that the patient is likely to achieve a successful vaginal delivery and would be a favourable candidate for induction. The lower the score, the less favourable the cervix is.
Calculating the Bishop score
The following components are assessed:
Cervical Score 0 1 2 3
Position Posterior Middle Anterior N/A
Consistency Firm Medium Soft N/A
Effacement 0-30% 40-50% 60-70% ≥80%
Dilation Closed 1-2cm 3-4cm ≥5cm
Foetal station -3 -2 -1, 0 +1, +2
The components can be remembered with the following mnemonic: Pregnancy Can Enlarge Dainty Stomachs! (Position, Consistency, Effacement, Dilation, Station).
Certain circumstances call for addition or subtraction of points (Bishops score modifiers):
1 point is added to the score for each of the following:
Presence of pre-eclampsia
Each previous vaginal delivery
1 point is subtracted for each of the following:
Post-dates pregnancy
No previous vaginal deliveries
Premature pre-term rupture of membranes

Rheumatic Fever:
is caused by group A strep infection as a complication
- Rheumatic fever
Definition
Rheumatic fever is a systemic complication of Lancefield group A beta-haemolytic streptococcal infection (typically a pharyngitis) that occurs two to four weeks post infection. Antibodies formed as a result of the infection cross-react with the myocardial tissue, causing the effects of rheumatic fever.
Epidemiology
The incidence of RF in developed countries is low.
It is more common in developing countries, particularly where there is overcrowding and poor access to healthcare.
Clinical findings
Rheumatic fever typically presents with various clinical findings. To aid diagnosis, findings are classified by the Jones criteria into major and minor manifestations.
Jones Criteria
A diagnosis is considered likely if there is:
Evidence of recent streptococcal infection (eg, history of scarlet fever, positive throat swab or rising or increased antistreptolysin O titre (ASOT) >200 U/mL or DNase B titre).
Plus two major criteria; or
One major and two minor criteria.
Major Jones criteria
Arthritis
Usually the earliest manifestation, typically a "flitting" or migratory polyarthritis affecting one joint then others in quick succession. Most commonly affected joints are the knees, ankles, elbows and wrists.
Pancarditis
Affects all layers of the myocardium, however endocardial inflammation may predominate causing valvulitis. This may manifest clinically as a tachycardia, new murmur or new conduction defect.
Sydenham's chorea
Neurologic disorder consisting of abrupt, non-rhythmic, involuntary movements along with muscular weakness and emotional disturbance. They are most frequently marked on one side and cease during sleep.
Erythema marginatum
Geographical pink/red, nonpruritic rash involving mainly the trunk, thighs and arms. Characteristically, the rash has raised, sharp outer edges with a diffuse clear centre, making a ring (and contributing to its alternate name, erythema annulare).
Subcutaneous nodules
Firm, mobile painless lesions
- Minor Jones criteria
Fever
Arthralgia (unless if arthritis meets major criterion)
Raised acute phase proteins (ESR and CRP)
Prolonged PR interval on ECG (except if carditis meets major criterion)
Management
Management of rheumatic fever involves multiple goals:
Eradication of group-A beta-haemolytic streptococcal infection
STAT dose of IV Benzylpenicillin, with a ten day course of Phenoxymethylpenicillin to follow
Analgesia for arthritic symptoms
Aspirin or non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen.
Aspirin should be used with caution in young children due to the small risk of Reye syndrome.
There is no evidence to suggest that NSAIDs help with outcomes related to carditis.
If carditis is complicated by heart failure
Glucocorticoids (e.g. Prednisolone) can provide benefit (NSAIDs should be stopped concurrently).
Diuretic treatment may also be necessary, and valve surgery if severe.
Sydenham's chorea is self-limiting and does not require treatment, however Haloperidol or Diazepam may be used for distressing symptoms or risk of harm.
Erythema marginatum is associated with rheumatic fever is temporary and doesn't require treatment, although antihistamines can help with pruritus.
Mechanism of valve complications
Rheumatic heart disease is a major cause of valvulopathy in children and young adults in the developing world. The most recent study in 2015 suggests that year there were over 30 million cases worldwide. Streptococcal antigens secondary to bacterial infection cross-reacts with the valve tissue, causing damage. Progressive damage commonly occurs in the years following acute rheumatic fever.
Mitral disease occurs in 70% of cases and is the most common affected valve; aortic valves are involved in 40% (most commonly regurgitation), tricuspid valves in 10% and pulmonary valves in 2%.
Common presentations of valve defects secondary to rheumatic heart disease
Mitral stenosis - isolated mitral stenosis it is the most commonly encountered single valve lesion secondary to rheumatic heart disease
Mitral regurgitation
Mixed mitral stenosis and regurgitation
Aortic regurgitation
Aortic stenosis (rare in isolation)
Tricuspid regurgitation or stenosis

Pelvic Inflammatory disease presentation:
Bilateral abdominal pain, raised ca125, inter-menstrual bleeding.

presents with: headache and visual changes(loss of visual acuity when changing posture is typical)
Mx: 1st line= weight loss
2nd line= acetazolamide
110
Bell's Palsy:
presentation: isolated facial weakness INVOLVING the forehead.
- if question says forehead sparing= think Stroke.
111
umbilical cord prolapse presentation:
presents as: foetal bradycardia and decelerations.
risk factors for umbilical cord prolapse= multiparity, polyhydramnios, artificial rupture of membranes

Ectopic Pregnancy classical presentation:
Unilateral Abdo pain with cramping for 6 weeks. scant vaginal bleeding of dark brown colour+previous history of pelvic inflammatory disease.
113
measles complication:
otitis media(think ear)
114
Herpex virus in pregnancy medication:
need a higher dose so 400mg 3 times a day(normal dose is 200), as in pregnancy there is a higher blood volume going around.
115
vasa praevia presentation triad:
painless vaginal bleeding, rupture of membranes, fetal bradycardia
Mx: is c section prior to rupture of membranes- if happens- need to do a emergency c section.,
- has an increased risk of fetal death.
116
if migraine/headache and in the history, patient is taking medication= think MOH(medication overuse headache)
treat by: stopping medication like paracetamol and codeine
117
red flags for headaches:
weight loss, neuro deficits, positional features, thunderclap nature of headache, altered GCS score
118
most likely cause of Non traumatic vertebral collapse in an elderly person:
metastatic malignancy
mx: give oral steroids and do Decompression.
119
sub dural haematoma risk factors:
recent trauma(falls), advanced age(more than 65yr), anticoagulant use, coagulopathy
120
commonest cause of intracerebral haemorrhage:
hypertension
121
body signs for HIV infection:
Maculopapular Rash on upper areas and mucosal ulcers.
classically= patients present with fever and cervical lympohadenopathy
122
women more than 50+bloating inv?
do ca125 bloods to rule out ovarian cancer!
123
obs pregnancy nerve you block for anesthetic:
puedendal nerve
124
viral induced wheeze vs. asthma:
viral wheeze= would not present over so long- would present over a few days with symptoms of breathlessness and wheeze
- asthma will have triggers like cat and dog etc.
125
metoclopramide: uses and side effect:
is an anti-emetic but has parkinsonian side effects
126
nsaids for periods:
transexamic: for mainly blood loss(menorrhagia)
mefenamic- for pain
127
blurred vision in one eye and loss of colour vision= what is affected?
optic nerve
other lesions:
-occipital lobe lesion= homonymous hemianopia+macular sparing
-optic chiasm= bitemporal hemianopia
128
lumbar spinal stenosis presentation:
neurogenic claudication with pain on exercise made WORSE by hip extension and BETTER by hip flexion.
129
diagnosis for left sided pelvic pain and peritonis and urine preg is negative?
ddx= could be ruptured ovarian cyst.
inital investigation- transvaginal uss
130
polyhydramnios risk factor:
maternal diabetes
131
guilian barre syndrome resp depression lung function test?
ONLY FvC not ratio.
132
miller fisher syndrome:
- is a variant of GBS
= presents with: ataxia, opthalmoplegia, areflexia
133
child should be able to run and jump by?
2.5 years
134
roseola pathogen?
HHV6
- can also feature nagayama spots.
135
nimodipine
is a CCB that prevents vasospasm-induced cerebral ischaemia
136
long term mx for stroke?
clopidogrel(anti-platelet) and could give atorvastatin(lipid-lowering) therapy
137

is adhesions and scarring caused by DILATION and curettage procedure.
138

bacterial tracheitis
140
measles investigation?
if rash onset 48 hour ago= do PCR for measles RNA as diagnostic
-if patient has presented 3 days after rash=measles specific IgM and igG do
