Adjectival Hyphens

error

"post-carotid endarterectomy"

Line 64:8 · Only use medical adjectival hyphens where the letters at the end and start of the compound word are the same, e.g. post-transplant. In this case, don't use the hyphen: 'post-carotid'.

Headings Spacing

error

"Ultrasound "

Line 104:1 · Never put spaces at either end of headings.

Strong List Colon Position

error

"MRA: vascular narrowings can be seen (see DSA)"

Line 132:8 · When enboldening an intro, the colon should not be bold. 'MRA: vascular'

"DWI: watershed infarcts can be seen"

Line 133:8 · When enboldening an intro, the colon should not be bold. 'DWI: watershed'

"perfusion/ASL: in the acute phase (≤30 days) there may be reduced global and regional CBF, which normalise by ~2 weeks after headache onset and remain normal in the remission phase (≥90 days); posterior regions show the most marked recovery ²³"

Line 134:8 · When enboldening an intro, the colon should not be bold. 'perfusion/ASL: in'

List Punctuation

error

"aneurysmal subarachnoid haemorrhage."

Line 151:42 · Do not put full stops at the end of a list item.

Ranges

warning

"RCVS affects women more commonly than men (F:M = 2.4:1) and usually presents between 20-50 years of age (mean 42 years), although it has also been described in children and adolescents ¹⁷. The mean age of presentation in men is a decade younger than the mean age of presentation in women."

Line 18:81 · Don't add words such as 'from' or 'between' to describe a range of numbers.

Acronyms

warning

"In 2016, a study proposed a set of criteria to diagnose reversible cerebral vasoconstriction syndrome and to distinguish it from primary angiitis of the central nervous system (PACNS) with a specificity of 98-100% and a similarly high PPV ⁷:"

Line 78:246 · 'PPV' has no definition. Spell it out if it's unfamiliar to the audience.

"Transcranial Doppler may show increased arterial velocities suggesting vasospasm and decreased luminal calibre of ICA, MCA, and ACA ⁸. Bedside ultrasound has been used for the follow-up of vasospasm ⁹."

Line 105:139 · 'ACA' has no definition. Spell it out if it's unfamiliar to the audience.

"perfusion/ASL: in the acute phase (≤30 days) there may be reduced global and regional CBF, which normalise by ~2 weeks after headache onset and remain normal in the remission phase (≥90 days); posterior regions show the most marked recovery ²³"

Line 134:26 · 'ASL' has no definition. Spell it out if it's unfamiliar to the audience.

"Ultrasound "

Line 104:1 · "Ultrasound " is not a recognised heading for this article type.

"Complications"

Line 143:1 · "Complications" is under the wrong parent heading (found under "Treatment and prognosis").

Oxford Comma

suggestion

"Headaches may be associated with photophobia, nausea and vomiting. Focal neurological deficits can occur, secondary to ischaemia or convexity subarachnoid haemorrhage. CSF studies are normal or near normal."

Line 94:37 · Use the Oxford comma in 'photophobia, nausea and vomiting'.

"In a minority of patients, ischaemia and stroke can occur²¹."

Line 144:21 · Use the Oxford comma in 'patients, ischaemia and stroke'.

Semicolons

suggestion

"perfusion/ASL: in the acute phase (≤30 days) there may be reduced global and regional CBF, which normalise by ~2 weeks after headache onset and remain normal in the remission phase (≥90 days); posterior regions show the most marked recovery ²³"

Line 134:216 · Use semicolons judiciously.

Commas

suggestion

"Vessel wall MRI (VW-MRI) may be a useful adjunct to conventional MRI, allowing differentiation between RCVS, where there is no or mild contrast enhancement of the affected arterial wall, and other causes of vascular narrowing, such as vasculitis, where there is intense contrast enhancement of the affected arterial wall, or intracranial atherosclerotic plaques, which focally demonstrate contrast enhancement ¹⁶."

Line 136:79 · More than 5 commas in a single sentence might make it more difficult to read.

suggestion

"History and etymology"

Line 145:1 · A bold element in the History and etymology section should be a person; it would be useful to have their lifespan details: '<h4>History and etymology</h4> What was later known as reversible cerebral vasoconstriction syndrome (RCVS) was first described by Call '
