Secondary Headaches: Non-Life Threatening Flashcards
Sinusitis and Glaucoma
Sinusitis is the inflammation of the mucous membranes in the _ _ _ _ _ _ _ _ _ _ _.
Parasinuses
Acute sinusitis lasts for how many weeks?
<12 weeks (3 months)
How long does sinusitis have to last before it is considered as chronic?
> 12 weeks (3 months)
Characteristics of the pain in sinusitis?
Pain over the sinuses (cheeks, forehead), blocked nose, post-nasal drip, hyposmia (loss of smell)
Sinusitis pain can radiate to which 2 places?
- Frontal headache
2. Teeth pain
Symptomatic treatment for sinusitis? (4)
- analgesia
- saline nasal irrigation
- nasal decongestants
- warm face pack
What formulation is corticosteroids given for sinusitis?
Nasally
What antibiotic is given for sinusitis? (*not systemically unwell)
PenV (phenoxymethylpenicillin)
Antibiotic given for sinusitis when systematically unwell
Co-amoxiclav
Symptoms of bacterial infection in sinusitis
- purulent discharge
- lasts >10 days
- fever
Which of the 2 worsens sinusitis pain - leaning forward or lying flat?
Leaning forward
Chronic inflammatory lesions of the nasal and paranasal sinuses are called?
Nasal polyps
Complications of sinusitis? (2)
- Orbital Cellulitis
2. Meningitis
Definition of Glaucoma
Strictly speaking, it is loss of the optic nerve fibres (optic neuropathy), typically due to an increase in intraocular pressure (IOP)
Main types of Glaucoma (3)
- Acute angle-closure glaucoma
- Closed open-angle glaucoma
- Normal tension glaucoma
Name the Glaucoma when there is a sudden physical obstruction in the angle between the iris and the cornea (anterior chamber angle) preventing aqueous drainage through the trabecular meshwork.
Acute Angle Closure Glaucoma
What type of pain presents in an Acute Angle Closure Glaucoma?
Rapid progressive and severe painful red eye that can radiate to a frontal headache
Clinical presentation of an Acute Angle Closure Glaucoma?
- Severe, rapidly progressive painful red eye
- Frontal headache
- Nausea and vomiting
- Hazy cornea
- Halo around lights
- Non-reactive/fixed mid-dilated pupil
Symptoms of Acute Angle Closure Glaucoma will worsen in a light or dark room?
Dark room - causes the pupils to dilate further
Why should patients not lie down in a dark room with Acute Angle Closure Glaucoma?
Lying down will increase an increase in IOP and cause the pupils to dilate further, making it worst.
NOTE: lying down without a pillow is used in management
What is the most common cause for the obstruction in Acute Angle-Closure Glaucoma?
Pupillary block
Investigations for Acute Angle-Closure Glaucoma (2)
- Tonometry - measures pressure in the eye (IOP)
2. Gonioscopy - analyses the anterior chamber angle
Medical management for Acute Angle-Closure Glaucoma? (4) (TIP - OBAPS)
- Referral to opthalmology
- Beta-blockers (Timolol) TOP - reduces fluid production
- Acetazolamide IV/PO
- Antiemetics/analgesia
- Pilocarpine TOP - pupil constriction (muscarinic)
- Steroid eye drops - anti-inflammatory
Definitive surgical management of Acute Angle-Closure Glaucoma?
Laser Iridotomy - make a hole in the iris to allow flow of aqueous humour from the posterior chamber to the anterior chamber.
