acute onset dyspnoea
(other presentation - dizziness, headache, facial plethora and distended veins)
Mx of SVCO
A-E
-keep head elevated 30 degrees, lose clothing
-dex 16mg
-endovascular stenting
-may give morphine to reduce respiratory distress
complications of SVCO
upper airway obstruction and stent thrombosis
most common lung cancer to cause SVCO
SCLC (as this is normally central and around the big vessels)
what signs do you get on an ECG from hypercalcaemia
shortened QT, heart block
three reasons you get hypercalcaemia of malignancy
PTHrP, mets, calcitriol (which causes more calcium absorption in the gut) from lymphomas
Mx of hypercalcaemia of malignancy
rehydrate with 3L in 24 hours, IV zoledronic acid, renal dialysis in refractory cases
Complications of hypercalcaemia of malignancy
pancreatitis, AKI, arrhythmias, seizures
symptoms of hypercalcaemia
abdo pain, bone pain, polyuria, polydipsia, nausea, confusion
two causes of raised ICP
SOL or obstructive hydrocephalus

MRI to look for brain mets
what chemo is known to cause seizures
cisplatin
how do you treat seizures in cancer
Benzos PRN
what Ix do you do if there is a pleural effusion
pleural fluid aspiration under US guidance and do MC+S
what is a parapneumonic pleural effusion?
a pleural effusion where there is an adjacent pneumonia and if pH is <7.2 this is an empyema
what is used to determine whether ascites is transudate or exudate
Serum-ascites albumin gradient
what is SAAG in a exudate
<11g/L
what is SAAG in a portal venous hypertension
> 11g/L
what investigations do you do for a ascites
an ascitic tap and then send it for MC+S and biochemistry
Mx of ascites
low sodium diet, potassium sparing diuretics (spironolactone/amiloride), paracentesis, indwelling catheter, peritoneovenous shunt (where the peritoneum is made to drain into the IJV), give abx prophylaxis if any episodes of SBP
what are the most common cancers to cause MSCC
breast, prostate, renal, myeloma, lung
how can MSCC be caused
can be due to direct compression of cancer, can be due to collapse of the vertebral body, can be due to pressure from intrabdominal malignancy
what reflexes are early signs of MSCC
hyperreflexia and positive babinski sign
