2A bits n bobs Flashcards

Small = adhesions and hernias Large = malignancy, diverticular disease and volvulous
How can you differentiate clinically between small and large bowel obstructions?
Small bowel = abdo pain is higher up, vomiting is earlier in onset (there will be a time when there is vomiting and stools are still passed - in LBO stopping passing stools occurs much more closely to symptoms onset), pain and bloating are often less severe in SBO

Staph. aureus infection
What is contact dermatitis?
Acute skin reaction to an irritant (affects everyone, no sensitization required) or allergen (sensitization required - type IV hypersensitivity reaction, can be delayed for up to 48-72 hours)
How can you diagnose and treat contact dermaititis?
Dx = patch test Tx = remove allergen/irritant, cold compress and topical steroids

Mx of psoriasis?
Avoid itching, emollients, sunlight exposure, tar preparations, topical steroids and vitamin D analogues
What is impetigo?
Highly contagious group A strep or staph. aureus infection. Leads to honey coloured crusted lesions on the face.
Bullae (staph scolded skin syndrome) are seen as cirlce lesions of erosion - inidicates more serious disease
Tx of impetigo?
Fusidic acid or mupirocin (both topical antibiotics).
Hydrogen peroxide if not systemically unwell and oral flucloxacillin if bullae.
School exclusion until crusted and healed or 48 hours after Abx treatment
What are the stages of hypertension?
Stage 1 = BP 140/90 - 159/99 AND ABPM of 135/85 - 149/94
Stage 2 = BP 160/100 - 180/120 AND ABPM >= 150/95
Stage 3 = Systolic BP >= 180 or diastolic >= 120
What is malignant hypertension? What should you do?
Increase in Bp to 180/120 or higher with signs of retinal haemorrhage and/or papilloedema.
Refer for same day specialist assessment - give labetalol
How do you manage BP in a <55 who is not black african or afro-carribean?
- ACEi or ARB (if cough from ACEi not tolerated)
- Add CCB or thiazide like diuretic (e.g. indapamide)
- All 3
How do you manage BP in a >=55 who is black african or afro-carribean?
- CCB
- Add ACEi (or ARB is preferable if black african or afro-carribean) or thiazide like diuretic (e.g. indapamide)
- All 3
What is the target blood pressure in HTN treatment?
<140/90 or <150/90 if >=80
What is the most common cause of heart failure?
Coronary artery disease followed by aortic stenosis and AF
Sx heart failure?
Dyspnoea (worse on exertion), cough (may be pink/white frothy sputum), orthopnoea, paroxysmal nocturnal dyspnoea, peripheral oedema
Ix of HF?
NT-proBNP.
>2000 = 2 week wait transthoracic echo
400-2000 = 6 week wait transthoracic echo
Mx of HF (with reduced ejection fraction)?
Loop diuretic, ACEi and beta-blocker
Start ACEi first if DM or fluid overload
Start Beta-blocker first if angina
Consider antiplatelet and statin. If Sx not controlled by diruetic ACEi and Beta-blocker consider adding aldosterone antagonist (e.g. spironolactone)
Mx of HF (with preserved ejection fraction)?
Loop diuretic and specialist refferal
Consider antiplatelet and statin
Sx of TB?
Cough, fever, night sweats, weight loss, sputum (rusty), haemoptysis
Ix of TB?
CXR = fibronodular opacities in the upper lobes +/- cavitation
Acid-fast bacilli go red on Zeihl-Neelsen stain
Mantoux skin test and interferon-gamma release assay can show presence of previous, latent or active TB
What is disseminated TB? What is seen on CXR?
AKA miliary TB
