A 67-year-old woman presented with confusion 2 days after a cholecystectomy. She had experienced some pain postoperatively, largely relieved by analgesia. On examination, she was disoriented, her heart rate was 66 beats per minute and her blood pressure was 162/82 mmHg. She only had minor discomfort of the abdomen. The urine sodium was 90mmol/l (NR 20-200mmol/l depending on hydration of patient).
The figure below shows the colours you would see on the dipstick after it has been dipped in the urine, and it was yellow in colour, consistent with an SG of 1.030.
Investigations:

Haemoglobin 130 g/L (115-165)
MCV 92 fL (80-96)
white cell count and platelet count normal

serum sodium        120 mmol/L (137-144)
serum potassium   3.7 mmol/L (3.5-4.9)
serum urea            3 mmol/L (2.5-7.0)

A

Syndrome of inappropriate anti-diuretic hormone

67
Q

A 46-year old Japanese female is found to have bilateral ovarian masses on imaging of the abdomen and had both ovaries removed. Histology revealed malignant signet ring cells containing mucin in both ovaries. What is the diagnosis?

A

Krukenberg tumour

Signet cells are present in gastric carcinoma. This is a gastric carcinoma that has metastasised to both ovaries. If both ovaries are affected, a primary elsewhere spreading to both ovaries is more likely. Gastric carcinoma is far more prevalent in Japan that anywhere else.

68
Q

Name the drug used for patients with type 2 diabetes which inhibits the enzyme alpha glucosidase in the brush border membrane of the small bowel.

A

Acarbose

*Leaves undigested sugar in the bowel giving wind as a side effect

69
Q

A

Gliptins such as alogliptin or sitagliptin

70
Q

A patient presents with weakness and is found to have a potassium of 2.4mM (NR 3.5 to 5.0). What is the likely acid-base abnormality if you check the patients arterial blood gas?

A

Metabolic alkalosis.

Remember hypokalaemic alkalosis. They go together, hypokalaemia causing alkalosis and alkalosis causing hypokalaemia

71
Q

A 40 year old presents to A&E with sever hypotension and shock. He appears dehydrated and tests reveal the following:

Sodium 123 mmol/L (135–146)
Potassium 6.8 mmol/L (3.5–5.3)
Glucose 2.9mM

Rank the following diagnoses in order of likelihood:

A. Primary hyperparathyroidism
B. Hypothyroidism
C. Conn's syndrome
D. Addison's disease
E. Gastroenteritis
A 
D. Addison's disease
E. Gastroenteritis
B. Hypothyroidism
A. Primary hyperparathyroidism
C. Conn's syndrome

Addison’s disease typically presents with shock, and causes a low sodium and a high potassium, and the lack of glucocorticoid also can cause a lower than average glucose (1). Gastroenteritis also can present with a low sodium and dehydration (2), although this is less likely as patients usually lose both sodium and potassium, although renal failure that results from severe dehydration can also cause hyperkalaemia.

Hypothyroidism (3) does not cause a low blood pressure, but can cause hyponatraemia when severe. Primary hyperparathyroidism (4) does not present like this, although if the high calcium causes renal failure, that could possibly cause the high potassium. Conn’s syndrome (5) is completely wrong, as those patients have a high blood pressure not a low one, and also a lot potassium.
