Q

Pharamacological Mx for pregnant woman with pre-existing diabetes?

A

Current guidelines for managing patients with pre-existing diabetes advise that metformin should be continued, but all other oral hypoglycaemic agents should be stopped and replaced with insulin such as isophane insulin. If patients are already established, and have good blood sugar control, on a long-acting analogue, such as insulin glargine, then this may continue.

Q

Types of cholesterol diseases?

A

Familial hypercholesterolaemia (FH) is inherited in an autosomal dominant fashion.
Patients still have significantly raised low-density lipoprotein (LDL) cholesterol levels and are at risk of atherosclerotic disease and, therefore, will require treatment.

Criteria for a definitive diagnosis of FH are total cholesterol greater than 7.5 mmol/l or LDL cholesterol level of greater than 4.9 mmol/l, alongside either tendon xanthomas in the patient or in first-/second-degree relatives or DNA evidence of a genetic defect.

Abetalipoproteinaemia condition associated with low levels of cholesterol.

Familial combined hyperlipidaemia both cholesterol and triglyceride levels are raised.

Q

Transverse myelitis?

A

Transverse myelitis is a rare neuro-immune condition that causes focal inflammation of the spinal cord. A typical patient presents with acute or subacute symptoms below the level of the lesion, including sensory impairment, motor weakness and bladder or bowel dysfunction.

It can occur as an independent post-infectious complication but also as part of the neuroinflammatory disease spectrum that includes multiple sclerosis and or neuromyelitis optica spectrum disorder.

The presentation of transverse myelitis consists of motor, sensory and autonomic dysfunction with an acute or subacute onset below the level of the lesion. The symptoms are usually bilateral but can be unilateral. The most common first symptom is sensory change (39%), weakness (25%) and pain (22%) with autonomic dysfunction in the form of bladder and bowel symptoms being less frequent first symptoms.

Ix: MRI spinal cord

Transverse myelitis has a sensory level and limb weakness below the level of the lesion.
