OSCE stations Flashcards
Additional stuff to ask in change in bowel habit history taking
Urgency? (Suggests proctitis)
Uncontrollable bowel motions (proctitis or overflow)
Nocturnal bowel passage (suggests organic disease)
Pain? Relieved by defaecation (IBS)
Diarrhoea:
- large volume, medium volume, made better with FASTING? - fasting makes better suggests OSMOTIC diarrhoea rather than SECRETORY
Investigations in acromegaly
ECG, visual fields and acuity
Bloods: Ca, PO4 (both increase), glucose. OGTT - look for decrease in GH in normal patients.
Imaging: MRI pituitary, CXR for cardiomegaly

Calcinosis: may fall off...surgically resect them Raynauds: Warm gloves etc. CCB (ACEI) Iloprost (prostacyclin infusion)
Esophageal dysmotility:
PPIs for reflux
Indications for surgery in Mitral Stenosis
- Pulmonary HTN & haemoptysis on minimal exertion..
- Valve area <1.5cm^2
- Recurrent thromboembolic events even with anticoagulation
- Surgery indications for Mitral regurgitation
- When is valve repair less likely to be successful
- When does MR murmur radiate to the carotid?
- Symptomatic, with good LV function…
- Ischaemic, infectious, rheumatic, significant calcification, when prolapse is bileaflet or anterior
- When posterior leaflet is defective, and regurgitant stream hits the LA close to the adjacent aortic root.
What is Gallavardin phenomenon
High frequency components of ESM radiates to the axils, and can mimic MR
Indications for surgery in AS
Symptomatic (ie. LVF)
Valvular pressure gradient >50mmHg
Valvular area <0.5cm^2
Aortic stenosis severity grading
Mild: valvular pressure gradient 50mmHg, area <0.5cm^2
Valve replacement complications
Surgery: GA complications, bleeding, infection etc.
Valve itself:
Thromboembolic (especially with artificial valves)
Valve dysfunction: valve leakage, dehiscence, obstruction (thrombi & clogging)
Haemolysis at valve
Endocarditis
Structural dysfunctions (mainly bio valve): calcification, cuts pal tear etc.
Non-structural dysfunctions: paravalvular leak, suture/tissue entrapment
Aortic regurgitation eponyms:
Quinke Corrigan De musset Miller Becker Rosenback Gerhard Langolfi
Dilatation of capillary nail bed Wide pulse pressure Head nodding Uvula systolic pulsations Retinal artery visible pulsations Liver pulsations Spleen pulsations Pupil dilates and constricts
Complications of bronchiectasis
