Q

Hypocalcaemia is an indication that kidney disease is chronic and not acute.

A

Chronic renal failure can lead to impaired conversion of 25-hydroxyvitamin D to its active form, which is needed for intestinal calcium absorption. This makes hypocalcaemia a marker that suggests the kidney disease is chronic and not acute, as an acute kidney injury is not associated with hypocalcaemia.

A

Norepinephrine and dopamine reuptake inhibitor, and nicotinic antagonist. Bupropion is an atypical antidepressant and smoking cessation aid.

Q

At what age is the neonatal blood spot screening test typically performed in the United Kingdom

A

The correct answer is Between fifth and ninth day of life. The neonatal blood spot screening test, also known as the ‘heel prick’ test, is typically performed between the fifth and ninth day of life in the United Kingdom. This timing allows for optimal detection of the five rare but serious health conditions that this test screens for: sickle cell disease, cystic fibrosis, congenital hypothyroidism, phenylketonuria (PKU), and medium-chain acyl-CoA dehydrogenase deficiency (MCADD). Performing the test within this timeframe ensures that any necessary treatment can be started as soon as possible while minimising the chance of false positive results.

What is Cholesteatoma?

A

Cholesteatoma is a non-cancerous growth of squamous epithelium that is ‘trapped’ within the skull base causing local destruction. It is most common in patients aged 10-20 years. Being born with a cleft palate increases the risk of cholesteatoma around 100 fold.

What is cataplexy?

A

The correct answer in this case is cataplexy. Cataplexy is a sudden and transient episode of muscle weakness, typically triggered by strong emotions such as laughter, anger or surprise.

Doxorubicin is an anthracycline chemotherapeutic agent that is known to cause dose-dependent cardiotoxicity. This cardiotoxicity can manifest as congestive heart failure, which may explain the patient’s increasing shortness of breath, third heart sound, and displaced apex beat.
