Q

After diagnosis of pneumonia, when should you image again and why.

A

You should image again after 6 weeks to ensure that the changes have resolves.
This is because the consolidation may have been hiding an underlying malignancy.

16
Q

What tumours commonly cause obstructions. (3)

A

Colon.
Ovary.
Gastric.

17
Q

Why might ovarian and gastric cancers cause obstructions.

A

Ovarian and gastric cancers have a tendency to metastasise across the peritoneum leading to “studding” across much of the bowel. This leads to interference with peristalsis and a functional bowel obstruction.

18
Q

What is the treatment of choice for a single transition point obstruction. (2)

A

Surgery or stenting.

19
Q

When would you treat obstruction conservatively.

A

Multifocal subacute bowel obstruction (often seen with ovarian cancer).

20
Q

What is involved in the conservative management of bowel obstruction. (5)

A 
Drip & Suck.
NBM.
Iv fluids.
Normalise electrolytes.
Chemo once resolved if possible. If not palliation may be only option.
21
Q

What are some metastatic causes of liver failure. (3)

A

Colon cancer.
Breast cancer.
Upper GI cancers.

22
Q

What are some obstructive oncological causes of liver failure. (3)

A

Pancreatic cancer.
Cholangiocarcinoma.
Portal metastases from other cancers.

23
Q

How do you treat parenchymal liver metastases.

A

Need systemic therapy if possible ASAP.

If the disease is so bad that liver function is deranged, then the patient is unlikely to be fit for chemotherapy.

24
Q

What are the main biochemical derangements that you seen in an obstructed liver.

A

Raised alkaline phsophate.

Raised bilirubin.

25
Q

What is needed to diagnose an oncologically obstructed liver.

A

Tissue biopsy.

26
Q

When is chemo a possibility in cancers causing an obstructed liver.

A

Usually not possible until the LFTs have normalised.

27
Q

What do end stage cancer patients often die of.

A

Renal impairment.

28
Q

How do you treat renal impairment in cancer (without hydronephrosis). (2)

A

IV fluids.

Antibiotics.

29
Q

What is the cause of renal impairment in cancer (without hydronephrosis). (3)

A

May be due to sepsis.
Fluid depletion.
Cancer burden.

30
Q

What is a common cause of hydronephrosis in cancer patients. (2)

A

Cervical cancer.

Bladder cancer.

31
Q

How would you treat hydronephrosis in cancer patients. (2)

A

Antegrade nephrostomy and stent.

Retrograde stent insertion.

32
Q

How do you treat pain in cancer patients. (7)

A

According to the WHO pain ladder.
Opioids.
Neuropathic agents.
Identifying the cause of the pain and addressing it.
Radiotherapy.
Chemotherapy.
Surgery (if the pain is caused by a mass).

33
Q

What cancers can cause spinal cord compression. (5)

A 
Breast. 
Lung. 
Kidney. 
Thyroid. 
Prostate.
34
Q

What are the symptoms of cord compression. (5)

A 
Weakness. 
Numbness. 
Urological dysfunction. 
Faecal dysfunction. 
Sexual dysfunction.
35
Q

Why is cord compression missed in cancer patients. (2)

A

Patients are usually seen in bed.

Symptoms of incontinence are too often dismissed as normal.

36
Q

What must you do in a patient with suspected cord compression. (3)

A

Full neurological examination.
PR exam.
Document bowel and bladder function.

37
Q

How do you manage a patient with cord compression. (6)

A 
16mg Dexamethasone .
Urgent MRI whole spine.
CT with spinal reconstruction.
Nurse supine.
Liase with Neurosurgery.
Liase with Oncology.
38
Q

Why is it important to catch spinal cord compression early. (4)

A

Nerves start to die within 24hrs of compression.
Surgical salvage better if caught early.
If rapid decline in hospital while receiving radiotherapy we will call surgeons for help.
Even if bedbound, if we can preserve continence there is possibility of being cared for at home.
