Antibodies graves
TSH receptor antibodies (TRAB): antibodies often present in the serum of patients with Graves’ disease that are directed against the TSH receptor
Antibodies hashimotos
antithyroid peroxidase (anti-TPO) antibodies and antithyroglobulin antibodies (anti-Tg)
What is levothyroxine
Levothyroxine is synthetic T4, and metabolises to T3 in the body.
Medications which may cause hypothyroidism
lithium
amiodarone
Pathophysiology graves
autoimmune condition where TSH receptor antibodies cause a primary hyperthyroidism. These TSH receptor antibodies are abnormal antibodies produced by the immune system that mimic TSH and stimulate the TSH receptors on the thyroid. This is the most common cause of hyperthyroidism.
unique features graves
Diffuse goitre (without nodules)
Graves eye disease
Bilateral exophthalmos
Pretibial myxoedema
Management hyperthyroid
propanolol for symptom relief then for actual treatment:
- Carbimazole

Management COPD
- SABA or SAMA
- IF not responsive: SABA + LABA + LAMA
- IF steroid responsive/asthmatic features: LABA + ICS,
- LABA, LAMA, ICS
Bicarbonate and COPD
Raised bicarbonate indicates they chronically retain CO2 and their kidneys have responded by producing more bicarbonate to balance the acidic CO2 and maintain a normal pH. In an acute exacerbation, the kidneys can’t keep up with the rising level of CO2 so they become acidotic despite having a higher bicarbonate than someone without COPD.
type 1 respiratory failure
Normal pCO2 with low pO2
Type 2 respiratory failure
Raised pCO2 with low pO2
COPD oxygen therapy
If retaining CO2 aim for oxygen saturations of 88-92% titrated by venturi mask
If not retaining CO2 and their bicarbonate is normal (meaning they do not normally retain CO2) then give oxygen to aim for oxygen saturations > 94%
managemnet acute exacerbation copd
Steroids, bronchodilators, antibiotics

L – Loss of joint space
O – Osteophytes
S – Subchondral sclerosis (increased density of the bone along the joint line)

oestoarthritis
MAnagement osteoarthritis
- Oral paracetamol and topical NSAIDs or topical capsaicin (chilli pepper extract).
- Add oral NSAIDs and consider also prescribing a proton pump inhibitor (PPI) to protect their stomach such as omeprazole.
- Consider opiates such as codeine and morphine but not long term

Genetic associations and antibodies rheumatoid
HLA DR4 (a gene often present in RF positive patients)
HLA DR1 (a gene occasionally present in RA patients)
Rheumatoid Factor (RF) present in 70%
