1st April [28th-4th] Flashcards
What is Ramsay Hunter syndrome?
Group of three neurological syndromes. Main presenteation is facial nerve palsy due to a herpes zoster virus.
Types 1-3 of Ramsay Hunter
type 1 = cerebellar syndrome [incl. myoclonic epilepsy, ataxia, tremor, dementia]
type 2 = facial nerve paralysis, vertigo, deafness, pain
type 3 = neuropathy deep palmar branch ulnar nerve [rareist]
When is orlistat used?
overweight people to lose weight
What is orlistat?
Class of medication called lipase inhibitors, prevents fat in foods being absorbed intestines, then removed by stools.
Muscles in the rotator cuff
Supraspinatus, infraspinatus, subscapularis and teres minor
What is rotator cuff tendonitis
Rotator cuff tendonitis refers to inflammation of the tendons of the rotator cuff muscles. This usually occurs secondary to repetitive use of the shoulder joint.
The muscle most commonly affected is the supraspinatus. During abduction, it ‘rubs’ against the coraco-acromial arch. Over time, this causes inflammation and degenerative changes in the tendon itself
Movements of the rotator cuff muscles
Subscapularis: Medial (internal) rotation of the shoulder
Supraspinatus: Abduction of the arm
- Necessary for the initial 0 to 15 degrees of shoulder abduction motion
- The deltoid muscle abducts the arm beyond 15 degrees
Infraspinatus: Lateral (external) rotation of the shoulder
Teres Minor: Lateral (external) rotation of the shoulder
Tx of a stye?
soak clean flannel in warm water, hold against eye 5-10m, repeat 3-4 times per day
Avoid wearing contact lenses and eye make-up until stye has burst and healed.
What is a stye?
A stye is caused by staphylococcal bacteria. This bacterium is found in the nose and is transferred easily to the eye when you rub your nose, then your eye.
Bacteria can cause inflammation or infection of the eyelash follicle, oil glands that drain through ducts into the eyelashes. When the duct is clogged, oil can’t drain and backs up into the glands. The gland becomes swollen and inflamed, causing the stye.
What is blepharitis?
Common ocular condiiton characterised by chronic inflammation, scaling, reddening and crusting of the eyelid.
Cx of blepharitis?
Not sight-threatening, but cna lead to permanent alterations in the eyelid margin
Cause blepharitis
Different variations of blepharitis can be classified as seborrheic, staphylococcal, mixed, posterior or meibomitis, or parasitic
Tx for menorrhagia
1st line - LNG-IUS Mirena [long-term Tx, in for at least q2m].
2nd line - tranexamic acid, NSIADs [like mefenmic acid reduces 25% menstrual loss], traneamic acid [50% loss], COC [50% reduction]
3rd line - with progestogens, either norethisterone or injected long-acting progestens like Depo-Provera every 12w
Tx for earwax
2/3 drops olive/almond oil twice daily for a few days. After 2w wax should fall out.
No evidence ear candles or ear vacuums ger ride of earwax.
What is a meningioma?
Tumour that forms on membranes that cover brain/spinal cord. Slow growing, as many as 90% are benign. Different Sx depend on what structures it presses on.
