Patient with headache, photophobia, nausea and vomiting, and a red watery right eye
He reports that these symptoms started 3 hours ago
On examination of his right eye he has a fixed, mid-dilated pupil with a cloudy cornea. His visual acuity is counting fingers in his right eye. Intraocular pressure is 58 mmHg (normal range 11 - 21 mmHg) in his right eye. Intraocular pressure in his left eye is 14 mmHg.
What is the definitive treatment for this condition?

Management of positive test for MRSA pre-surgery
Chlorhexidine wash and intranasal mupirocin
What does tissue factor pathway inhibitor do?
Forms a quaternary structure with the tissue factor which is inactive and stops it activating the clotting cascade

Spiral fracture
Non-emergency management of hyperkalaemia (<6mmol)
Calcium resonate

Features of GORD in a young infant
Milky vomits but still feeding well
Crying and arching their back when laid flat
Management of GORD in infants
Burp them after feeds and keep them upright
Gaviscon
Surgical option = fundoplication
What drug can you give pre C-section at term?
Omeprazole
Reduces risk of aspiration and GORD in the surgery
1st line analgesia for renal colic
IM diclofenac or PR I believe
Mx of recurrent VT e.g. after MI

A 20-year-old contact lens wearer presents to eye casualty with severe eye pain around her right eye and decreased visual acuity.
She describes the pain as 10/10 in severity and complains of a sensation of a foreign body being stuck in her eye.
Examination of the right eye is difficult due to photophobia but there is significant tearing and discharge. There is no history of eye trauma but she recently swam in a lake whilst wearing her lenses.
