Q

Additional stuff to ask in change in bowel habit history taking

A

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

Q

Indications for surgery in Mitral Stenosis

A
  1. Pulmonary HTN & haemoptysis on minimal exertion..
  2. Valve area <1.5cm^2
  3. Recurrent thromboembolic events even with anticoagulation
17
Q
  1. Surgery indications for Mitral regurgitation
  2. When is valve repair less likely to be successful
  3. When does MR murmur radiate to the carotid?
A
  1. Symptomatic, with good LV function…
  2. Ischaemic, infectious, rheumatic, significant calcification, when prolapse is bileaflet or anterior
  3. When posterior leaflet is defective, and regurgitant stream hits the LA close to the adjacent aortic root.
18
Q

What is Gallavardin phenomenon

A

High frequency components of ESM radiates to the axils, and can mimic MR

19
Q

Indications for surgery in AS

A

Symptomatic (ie. LVF)
Valvular pressure gradient >50mmHg
Valvular area <0.5cm^2

20
Q

Aortic stenosis severity grading

A

Mild: valvular pressure gradient 50mmHg, area <0.5cm^2

21
Q

Valve replacement complications

A

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

22
Q

Aortic regurgitation eponyms:

Quinke
Corrigan
De musset
Miller
Becker
Rosenback
Gerhard
Langolfi
A
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
23
Q

Complications of bronchiectasis

A
Recurrent pneumonias
Haemoptysis (can be life-threatening)
Brain abscesses
Pneumothorax, pleural effusions, pleurisy etc.
Amyloidosis
24
Examination features of Charcot-Marie tooth
Champagne bottle legs - wasting of small muscles DISTALLY (c/w MND where there is globalised muscle wasting) Pes cavus, or pes planus, foot drop. Thickened calluses, hammer toe. Toe (and finger clawing) Lateral popliteal nerve thickening, and greater auric ulnar nerve thickening Scoliosis May get some sensory changes
25
Other uncommon features CMT is associated with
"ROP" SPOARP Retinitis Pigmentosa Optic atrophy Spastic paraparesis
26
Places where lacunar infarcts can occur and aetiology
Internal capsule Pons (ataxia, partial hemispheresis) Basal ganglia (hemiballismus) Thalamus (mainly sensory) Hypertension, rupture of Charcot-Bouchard micro aneurysms causing lacunae haematomas that leave small area of infarct.
27
Posterior circulation syndrome
Bilateral motor or sensory signs, not secondary to brainstem compression by a large supratentorial lesion Cerebellar signs, unaccompanied by ipsilaterally motor deficits (would be ataxic hemiparesis) Diplopia Crossed signs (ie. ipsilateral face and contralatetal limb) Hemianopia alone, or with above signs
28
Lacunar syndromes 1. Pure motor 2. Pure sensory 3. Ataxic 4. Sensorimotor
1. Unilateral, pure motor deficit Clearly involving 2/3 areas (face, arms, legs) Whole limb being involved 2. Unilateral pure sensory symptoms 2/3 areas Whole limb involved 3. Ipsilateral cerebellar and corticospinal tract signs +/- dysarthria No higher cerebral dysfunction or visual field defect 4. Pure motor and pure sensory stroke combined, without higher cortical dysfunction or visual field defect
29
Treatments of pleural effusions
1. Treat underlying cause 2. Chest drains for large pleural effusions 3. Pleurodesis (eg. With doxycycline, talc, bleomycin etc) for recurrent effusions. Pleural drain - can lead to the outside or inside..(pleuroperitoneal shunt) Remove the pleura
30
Causes of hydropneumothorax
Iatrogenic Gas-forming organisms Trauma
31
Main complications of total hip replacement (THR)
Deep infection DVT Dislocation (esp. when sit down or squat etc) Nerve damage (sciatic with posterior approach causing foot drop, anterolateral approach can damage superior gluteal nerve -> trendelenberg gait from weak abductors)
32
Causes of positive trendelenberg test
Hip dislocation Greater trochanter fracture SUFE Proximal myopathy etc and nerve damages leading to abductor weakness Any painful hip disorder which causes gluteal inhibition...
33
Causes of generalised papulosquamous eruptions on trunk
(2x pityriasis; 2x infectious; 2 x "D's"; 2 x "P's" ``` Pityriasis rosea Pityriasis versicolor Generalised pustular psoriasis Pemphigus Secondary syphilis Chickenpox Chronic superficial Dermatitis Drug eruptions ```
34
Management of Crohn's disease
Conservative: MDT etc. dietary advice... Medical: 5-ASA: azathioprine, steroids, anti-TNFs (infliximab & adalimumab), acute flare up: may need to treat underlying infections (metronidazole) Surgical: proctopancolectomy
35
Extra-bowel manifestations of Crohn's disease
Eyes: anterior uveitis, episcleritis Skin: pyoderma gangrenosum, nodosum Joints: arthritis (reactive), sacroilitis Organs:
36
Extra-bowel manifestations of UC
Eyes: anterior uveitis, episcleritis Skin: pyoderma gangrenosum, nodosum Joints: arthritis, sacroilitis Organs: increased cancer in bowel, PSC
37
Causes of anaemia in Rheumatoid arthritis
Chronic disease Drugs and marrow suppression (gold penicillamines, MTX etc) Folate deficiency Felty syndrome
38
Causes of INO
``` Demyelinating diseases - MS Vascular diseases Pontine glioma Inflammatory lesions of the brainstem Drugs - phenytoin, carbamazepine ```
39
What is Fisher's one and a half syndrome?
Lesion in MLF and PPRF (and 6th nerve nucleus?) on same side. Therefore cannot move eyes horizontally at all except abduct the opposite eye
40
Other associated abnormalities of neurofibromas
``` Lung cysts Retinal hamartomas Skeletal lesions: erosive bony defects, and intraosseous cystic lesions, skull dysplasia Aqueductal stenosis Sarcomatous changes ```
41
Stuff to look for in NF1
``` >6 cafe-au lait spots Axillary freckling Lisch nodules >2 neurofibromas Plexiform neurofibromas Optic gliomas (treat with radiation - papilloedema on fundoscopy) ```
