Another One Flashcards
Enzyme raised in mumps
Amylase
Impaired oxidative killing is in what condition

What test? Low aldosterone

What test? Raised plasma glucose
Fasting glucose, oral glucose tolerance test
- Primary Hyperparathyroidism
- Secondary Hyperparathyroidism
- Tertiary Hyperparathyroidism
- Hypoparathyroidism
- Osteomalacia
- Paget’s
- Osteoporosis
- Pseudohypoparathyroidism
- Pseudopseudohypoparathyroidism
- Familial Hypocalciuric Hypercalcaemia
- Raised PTH due to an adenoma
- Secondary to low calcium (kidney disease)
- Chronic secondary hyperparathyroidism causes hyperplasia of the parathyroid gland
- Primary is due to parathyroid gland defect so not enough PTH secreted. Can be secondary to surgery
- Vit D deficiency, so raised PTH and ALP
- Raised ALP, defective bone mineralisation
- Normal, due to reduced bone density
- Resistance to PTH, so PTH levels are up and calcium is low
- Normal bone biochehmistry
- Raised calcium because of mutation which means calcium level estimation is inaccurate so PTH is released more
- Raised TSH, Low T4
- Raised TSH Normal T4
- Raised TSH, Raised T4
- Low TSH, Raised T4
- Low TSH, Low T4
- Raised TSH, Normal T4 in severely sick patient
- Primary hypothyroidism
- Subclinical hypothyroidism
- Secondary hyperthyroidism (TSH tumour OR thyroid hormone resistance)
- Primary hyperthyroidisim
- Secondary hypothyroidism
- Sick euthyroid
Conn’s Syndrome aldosterone:renin ratio
High
Mechanism of non functioning adenoma
Stalk obstructed, so dopamine can’t inhibit prolactin function. Symptoms are amenorrhoea, galactorrhoea and gynaecomastia
Macroadenoma signs and symptoms
Low levels of TSH, GH, ACTH and bitemporal hemianopia
Calcitonin is produced by…and is elevated in what tumour
Parafollcular cells and acts on reducing Ca levels in the blood. Elevated in medullary thyroid tumour. Congo red stain can be used because of deposition

Enzyme raised in rhabdomyolysis
Creatinine kinase
A condition that causes hepatic cirrhosis and portal hypertension in some and cardiomyopathy in others
Haemochromatosis
present with joint pain, splenomegaly, skin rash, nerve and kidney involvement – Ig precipitate at low temperatures.
Hepatitis C Cryoglublinaemia
megakarycotes dominate BM, 50% JAK-2, platelet count > 600 x 109, see DVT or PEs or haemorrhage (as platelets dysfunctional), erythromelalgia, splenomegaly, dizziness, headache, visual disturbances
Essential Thrombocythaemia
– where haemoglobin in urine due to viral infection then on rewarming they get complement mediated haemolysis – see Donath-Landsteiner antibodies, it is self-limiting, transfusion if severe anaemia.
Paroxysmal Cold Haemoglobinuria
TTP
MAHA Fever Renal failure CNS signs Haematuria Low platelets
antibodies against GpIIb/IIIa on platelets; self-limiting in children, chronic in adults
ITP
<37*C, IgM, positive DAT, spherocytes, often with Raynaud’s, causes = primary idiopathic, lymphoma, infections – EBV and mycoplasma, treat underlying condition, avoid cold and give chlorambucil.
Cold Agglutinins Cold AIHA
Low ferritin anaemia
IDA
Raised ferritin anaemia
Anaemia of chronic disease
Normal ferritin anaemia
Thalassaemia
When is TIBC low rather than high?
Haemochromatosis and chronic haemolysis
Anti-Xa assay
Monitor heparin
Fibrinogen is low in
Liver disease and DIC
D-dimer is to rule out
PE
Physiological changes in pregnancy
Mild anaemia but RBC mass rises Plasma volume also rises so net dilution Macrocytosis Neutrophilia Less platelets, but bigger size
Pre-eclampsia, low platelet + abnormal clotting
DIC
Haedache and Seizures, signs of MAHA
TTP
After transfusion, temperature is over 40
Bacterial infection
Recurrent hypoglycaemic attacks
Insulinoma
