Q

Haemochromatosis Iron sudies

TIBC
A

High serum iron

High ferritin - inc iron = inc ferritin in compensatory atttempt to increase intracellular iron storage

Low transferrin - inc iron = dec trasnferring to prevent more iron from plasma protein bound in blood

High trasnferring sat - high iron and low trasnferrin

Low total iron binding capacity - measure of blood’s capacity to bind iron to transferring. As trasnferring low, inc diff for iron to bind

Q

Test to diagnose ankylosing spondylitis

A

Schober’s

During this clinical test, a mark is made on the skin overlying the 5th lumbar spinous process (usually at the level of the posterior superior iliac spine) and a second mark is made 10 cm above the first. The patient is then asked to bend over, which flexes the spine. In normal subjects, the distance between the two marks will increase to > 15 cm. If the distance is less than 15 cm, this indicates a reduction in spinal flexion, which supports a diagnosis of ankylosing spondylitis.

Q

Hypertension NICE guidelines

A

STEP 1: Patients < 55 years old should be offered an ACE inhibitor (ACEI e.g. enalapril) or angiotensin receptor blocker (ARB e.g. losartan). Patients > 55 years old and patients of Afro-Caribbean origin should be offered a calcium channel blocker (CCB e.g. amlodipine) or, if there is any evidence (or high risk) of heart failure, a thiazide-like diuretic (e.g. bendroflumethiazide).

STEP 2: Offer a CCB with an ACEI or ARB. If CCBs are not suitable, a thiazide-like diuretic can be used instead.

STEP 3: Offer a combination of an ACEI or ARB with a CCB and a thiazide- like diuretic.

STEP 4: If these three steps are unsuccessful in gaining control of blood pressure, it is considered ‘resistant hypertension’. Expert help should be sought and a 4th antihypertensive may be added e.g. spironolactone.

A

Polycythaemia rubra vera is a primary polycythaemia caused by clonal proliferation of myeloid stem cells.

Secondary polycythaemia is caused by natural or artificial increases in erythropoietin (EPO) production. This increase in EPO production may be appropriate (e.g. in response to chronic hypoxia in COPD) or inappropriate (e.g. EPO abuse amongst athletes).

Q

Light detection

A

Light is detected by rods and cones in the retina, which then generate an electrical
signal that passes along the optic nerve. The optic nerve contains two main bundles
of nerves, one will carry signals from the medial half of the retina (responsible for the
temporal half of the visual field) and the other will carry signals from the lateral half of
the retina (responsible for the nasal half of the visual field). The two optic nerves will
meet at a point called the optic chiasma. At the chiasm, the neurons from the lateral
half of the retina will continue to the optic tract on the ipsilateral side. Whereas the
neurons from the medial half of the retina will decussate at the chiasm and join the
optic tract on the contralateral side. Therefore, the optic tract in the left hemisphere is
responsible for the right half of the visual field and the optic tract in the right
hemisphere is responsible for the left half of the visual field. The optic tract ends at
the lateral geniculate nucleus (LGN) in the thalamus. Optic radiations link the LGN to
the visual cortex. The optic radiations have an upper division (passing through the
parietal lobe) and a lower division (passing through the temporal lobe). The upper
division is responsible for the inferior quadrant of the visual field (e.g. the upper
division of the optic radiation in the right hemisphere, is responsible for the left
inferior quadrant) and the lower division is responsible for the superior quadrant. The
primary visual cortex will then integrate the information from these inputs.
Damage to the optic nerve will lead to complete loss of vision in one eye, with intact
vision in the other eye. Disruption of the optic chiasm (e.g. by pituitary tumours)
mainly affects the neurons from the medial half of the retina, which decussates at the
chiasm. This leads to bitemporal hemianopia. The optic tract carries information from
one half of the visual field – i.e. right half of the visual field in the left optic tract and
vice versa. Disruption of this tract leads to homonymous hemianopia (loss of one half
of the visual field). Disruption of the upper and lower divisions of the optic radiations
will lead to superior or inferior homonymous quadrantopia.
This patient has left homonymous hemianopia, meaning that his right optic tract has
been damaged.
