February Flashcards
Pulmonary oedema is an indication for what in a patient with acute kidney injury?
Haemodialysis
Proliferative diabetic retinopathy is treated with…
Panretinal laser photocoagulation
What are the main features of secondary syphilis and when does it occur?
Secondary features - occurs 6-10 weeks after primary infection
systemic symptoms: fevers, lymphadenopathy, rash on trunk, palms and soles buccal ‘snail track’ ulcers (30%) condylomata lata (painless, warty lesions on the genitalia)
Stop sertraline when?
6 months after RESOLUTION
Common symptoms of early lymes disease?
Symptoms include joint pains, facial nerve palsy, palpitations, headaches and fever.
What rash is caused by Borrelia burgdorferi?
Erythema migrans (Bulls eye rash)
When to perform HIV testing:
Testing for HIV in asymptomatic patients should be done at 4 WEEKS AFTER SUSPECTED EXPOSURE.
If this result is NEGATIVE offer a repeat test at 12 weeks
What is the screening performed for all diabetic patients to assess for nephropathy?
All diabetic patients require annual screening for albumin:creatinine ratio (ACR) in early morning specimens.
Smoking cessation in pregnancy give?
NRT
Pregnant women who smoke: nicotine replacement therapy should be offered, varenicline and bupropion are contraindicated
What iron studies are seen in iron deficiency anaemia?
Low transferrin saturation, low ferritin, high TIBC
Low transferrin saturation can be thought of as fewer binding spots taken up by iron, low ferritin can suggest less iron has been stored, and a high TIBC means there are more binding spots free for iron to take up, therefore suggesting low iron in the body.
Treatment for oesophageal varicies:
Variceal band ligation is the NICE recommended method of stopping oesophageal variceal bleeding. Sengstaken tube and TIPSS is recommended if this fails. Propranolol is used as bleeding prophylaxis.
Contralateral homonymous hemianopia with macular sparing and visual agnosia which artery is occluded?
Posterior cerebral artery
First line test for acromegaly?
Serum IGF-1 levels are now the first-line test for acromegaly
Gonorrhoea tx
Intramuscular ceftriaxone is the treatment of choice for Gonorrhoea
PE treatment if pregnant?
LMWH
Apixaban is teratogenic
How does hypophosphataemia present?
May result in significant muscle weakness, including myocardial muscle (→ cardiac failure) and the diaphragm (→ respiratory failure).
Cardiac Dysfunction: Hypophosphatemia can impair myocardial contractility, leading to heart failure. It may also cause arrhythmias due to its role in maintaining normal cellular electrophysiology.
Respiratory Failure: Phosphate is essential for ATP production, necessary for respiratory muscle function. Severe hypophosphatemia can lead to muscle weakness, including the diaphragm and intercostal muscles, potentially resulting in acute respiratory failure.
Neurological Complications: These can range from confusion and seizures to coma, attributable to disturbed ATP metabolism in the central nervous system.
Haematological Effects: Reduced 2,3-diphosphoglycerate levels in erythrocytes affect oxygen release from haemoglobin, leading to tissue hypoxia. Hypophosphatemia can also result in hemolysis.
Rhabdomyolysis: Phosphate depletion impairs ATP production in muscles, which can lead to muscle breakdown and rhabdomyolysis.
Patients with GORD being considered for fundoplication surgery require what first?
Oesophageal pH and manometry studies
Antibiotic treatments for meningitis?
Less than three months or over 50yrs = IV cefotaxime + amoxicillin
3months - 50yrs give IV cefotaxime (or ceftriaxone).
If two pills are missed, between days 8-14 of the cycle, no emergency contraception is required, as long as the previous 7 days of COCP have been taken correctly
If two pills are missed, between days 8-14 of the cycle, no emergency contraception is required, as long as the previous 7 days of COCP have been taken correctly
If a patient with a STEMI is too far from a PCI centre how should the be managed?
Fibrinolysis (with streptokinase) + fondaparinux.
Fibrinolysis is given immediately with fibrinolytic agents e.g. streptokinase. An antithrombin like fondaparinux is given with fibrinolysis.
Severe campylobacter infection give…
Clarithromycin
Adverse effects of tamoxifen:
Menstrual disturbance: vaginal bleeding, amenorrhoea
Hot flushes - 3% of patients stop taking tamoxifen due to climacteric side-effects
Venous thromboembolism
Endometrial cancer
Hydroxychloroquine - may result in a severe and permanent retinopathy
Hydroxychloroquine - may result in a severe and permanent retinopathy
H.pylori is associated with what haematological malignancy?
MALT lymphoma: this is a cancer that arises from the mucosal-associated lymphoid tissue. It is a response to chronic Helicobacter pylori infection.
Coeliacs disease is associated with what haematological malignancy?
EATL: Coeliac disease increases the risk of developing enteropathy-associated T cell lymphoma
Anti-GBM disease typically presents with what?
Anti-GBM disease typically presents with haemoptysis + AKI/proteinuria/haematuria
TB diagnosis
Sputum culture
Chvostek’s sign =
Hypocalcaemia, tapping over parotid (CN7) causes facial muscles to twitch
Reducing dietary sodium is a key intervention in patients with ascites
Reducing dietary sodium is a key intervention in patients with ascites
