finals neuro/rheum Flashcards
how to manage hypogycaemia?
mild hypo (patient conscious)
- A-E
-consume fast acting carbs (e.g. glucose tablet, a small can of coke, sweets or fruit juice0
-consume some slow-acting carbs after (e.g. toast)
- AVOID CHOCOLATE
severe hypo (e.g. seizures/ patines unconscious)
- A-E
- Administer 200ml of 10% dextrose IV
- IF no IV access administer 1mg/kg of glucagon IM (wont work if hypo is caused by alcohol because of drug mechanism)
what is the first line treatment for Alzheimer’s disease?
Donepezil
how does chronic mesenteric ischaemia present?
Diffuse, colicky abdominal pain, which worsens after eating
Significant weight loss, as patients avoid eating due to the pain
Gastrointestinal bleeding, presenting as melaena or haematochezia (secondary to mucosal sloughing)
An epigastric bruit may be present, indicative of turbulent flow in the narrowed vessels.
what are some examples of aura with migraines and what is it?
Aura can affect vision, sensation or language. Visual symptoms are the most common. These may be:
Sparks in the vision
Blurred vision
Lines across the vision
Loss of visual fields (e.g., scotoma)
Sensation changes may include tingling or numbness. Language symptoms include dysphasia (difficulty speaking).
what does a hemiplegic migraine mimic that is it important to rule out?
stroke
what 3 drugs can be given for migraine prophylaxis and when shouldn’t they be given?
-Propranolol (a non-selective beta blocker)
-Amitriptyline (a tricyclic antidepressant)
-Topiramate (teratogenic and very effective contraception is needed)
propanalol- asthma
topiramate- caution in women of childbearing age
when should triptans be taken and can you take another if it doesn’t work?
Triptans (e.g., sumatriptan) are taken as soon as a migraine headache starts. They should halt the attack. If the attack resolves and then reoccurs, another dose can be taken. If it does not work the first time, another second dose should not be taken for the same attack.
what pain relief shouldnt be taken for migraines and can actually make them worse?
opiods
what is the management for tension headaces?
Reassurance
Simple analgesia (e.g., ibuprofen or paracetamol)
Amitriptyline is generally first-line for chronic or frequent tension headaches.
how do cluster headaches present?
Cluster headaches are severe and unbearable unilateral headaches, usually centred around the eye.
Cluster headaches cause severe pain. They are sometimes called “suicide headaches” due to their severity.
Associated symptoms are typically unilateral:
Red, swollen and watering eye
Pupil constriction (miosis)
Eyelid drooping (ptosis)
Nasal discharge
Facial sweating
how to manage a cluster headache? acute and phrophylaxis
Treatment options during acute attacks are:
- Triptans (e.g., subcutaneous or intranasal sumatriptan)
- High-flow 100% oxygen (may be kept at home)
Verapamil is the first line for prophylaxis (to prevent attacks).
where do cluster headaches get their name from?
They are called cluster headaches as they come in clusters of attacks and then disappear for extended periods. For example, a patient may suffer 3-4 episodes a day for weeks or months, followed by a pain-free period lasting several years. Attacks last between 15 minutes and 3 hours.
A typical patient is a 30-50 year old male smoker. They may have triggers, such as alcohol, strong smells or exercise.
what is the first line treatment for trigeminal neuralgia?
Carbamazepine
what condition is trigeminal neuralgia commonly associated with?
multiple sclerosis
how does trigeminal neuralgia present?
intense facial pain in the distribution of the trigeminal nerve, which has three branches
90% of cases unilateral
pain comes on suddenly and can last seconds to hours. It may be described as an electricity-like, shooting, stabbing or burning pain. It may be triggered by touch, taking, eating, shaving or cold.
what are the three brancehs of the trigeminal nerve
v1- opthalmic
v2- maxillary
v3- mandibular
difference between orbital and pre orbital cellulitis. How to distinguish between them?
pre orbital -
an eyelid and skin infection in front of the orbital septum (in front of the eye). It presents with swollen, red, hot skin around the eyelid and eye.
orbital cellulitihs an eyelid and skin infection in front of the orbital septum (in front of the eye). It presents with swollen, red, hot skin around the eyelid and eye. infection of the actual eye
A CT scan can help distinguish them. aslo orbital has painful eye movements/ reduced eye movement and visual changes whereas pre orbital is just the swelling of eyelid
symptoms and treatment of preoribtal cellulits?
swollen, red, hot skin around the eyelid and eye.
Treatment is with systemic antibiotics (oral or IV). Preorbital cellulitis can develop into orbital cellulitis, so vulnerable patients (e.g., children) or severe cases may require admission for monitoring.
symptoms and treatment of oribtal cellulits?
Orbital cellulitis is an infection around the eyeball involving the tissues behind the orbital septum. Symptoms include pain with eye movement, reduced eye movements, vision changes, abnormal pupil reactions, and proptosis (bulging forward of the eyeball).
Orbital cellulitis requires emergency admission under ophthalmology and intravenous antibiotics. Surgical drainage may be needed if an abscess forms.
different between complex and simple febrile convulsion?
Febrile convulsions can be described as complex when they consist of partial or focal seizures, last more than 15 minutes or occur multiple times during the same febrile illness.
Does having febrile seizures increase the risk of having epilepsy in the future?
Children who have had a febrile seizure have a slightly increased chance of having epilepsy later in life, but this is rare.
2-5%
what can Alpha-1 Antitrypsin Deficiency lead to?
lung and liver problems
MAINTENANCE FLUID REQUIREMENTS IN CHILDREN
1st 10kg of bodyweight at 100ml/kg/day
2nd 10kg of bodyweight at 50ml/kg/day
Remaining bodyweight at 20ml/kg/day
The fluid type routinely used is 0.9% sodium chloride + 5% dextrose. Potassim is added as required depending on their U&Es.
What does LOSS stand for oseoarthiritis?
L – Loss of joint space
O – Osteophytes (little bits of exta bone growing)
S – Subarticular sclerosis (increased density of the bone along the joint line)
S – Subchondral cysts (fluid-filled holes in the bone)
