Adjectival Hyphens

error

"iatrogenic: post-surgical complication"

Line 24:16 · 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-surgical'.

"post-ultralow anterior resection"

"Parks classification: trans-, inter-, supra-, or extra-sphincteric"

Line 100:41 · 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: 'trans-,'.

Units

error

"an exception to this rule is external openings >3cm from the anal verge, anterior to the transverse anal line, as most originate as a primary or secondary tract from the posterior midline consistent with a prior horseshoe abscess ⁴"

Line 39:56 · Put a space between the number and the unit in '3cm'.

Strong List Colon Position

error

"grade 1: simple linear intersphincteric"

Line 54:8 · When enboldening an intro, the colon should not be bold. 'grade 1: simple'

"grade 2: intersphincteric with abscess or secondary tract"

Line 55:8 · When enboldening an intro, the colon should not be bold. 'grade 2: intersphincteric'

"grade 3: transsphincteric"

Line 56:8 · When enboldening an intro, the colon should not be bold. 'grade 3: transsphincteric'

"grade 4: transsphincteric with abscess or secondary tract within the ischiorectal fossa"

Line 57:8 · When enboldening an intro, the colon should not be bold. 'grade 4: transsphincteric'

"grade 5: supralevator and translevator extension"

Line 58:8 · When enboldening an intro, the colon should not be bold. 'grade 5: supralevator'

"T1: isointense to muscle"

Line 82:8 · When enboldening an intro, the colon should not be bold. 'T1: isointense'

"T2: high signal compared to fat"

Line 83:8 · When enboldening an intro, the colon should not be bold. 'T2: high'

"T2-FS: high signal compared to fat"

Line 84:8 · When enboldening an intro, the colon should not be bold. 'T2-FS: high'

"T1 C+: rim enhancement"

Line 85:8 · When enboldening an intro, the colon should not be bold. 'T1 C+: rim'

Strong

warning

"Goodsall's rule was historically used to predict the course of the fistula and internal opening. It states that the internal opening of the fistula is dependent on where the fistula is located relative to the 'anal clock' (i.e. with the patient in the lithotomy position, anterior is 12 o'clock and posterior is 6 o'clock) and the transverse anal line (a line drawn from 9 o'clock to 3 o'clock):"

Line 35:4 · Generally, don't use bold in text: 'Goodsall's rule'

"if the external opening is anterior to the transverse anal line, there will be a (usually simple) direct radial fistulous tract"

Line 37:35 · Generally, don't use bold in text: 'anterior '

"if the external opening is posterior to the transverse anal line, there will be a tortuous (and often more complex) fistulous tract that enters posteriorly in the midline (6 o'clock)"

Line 38:35 · Generally, don't use bold in text: 'posterior '

Eponym Apostrophe

warning

"These can also be applied in combination. Infusion of hydrogen peroxide into the fistulous tract renders it hyperechoic, thus facilitating its delineation. Doppler interrogation can show hyperaemia in active Crohn's disease."

Line 76:215 · Radiopaedia prefers the non-possessive eponym: 'Crohn's disease'.

Acronyms

warning

"T2-FS: high signal compared to fat"

Line 84:19 · 'FS' has no definition. Spell it out if it's unfamiliar to the audience.

"chronic tracts have low signal on both T1- and T2-WI and will not show contrast enhancement"

Line 94:58 · 'WI' has no definition. Spell it out if it's unfamiliar to the audience.

Prefix Hyphens

warning

"Parks classification: trans-, inter-, supra-, or extra-sphincteric"

Line 100:68 · A prefix takes a hyphen only to avoid a duplicate letter: 'extra-sphincteric'.

Commas

suggestion

"The most commonly accepted pathophysiology is the cryptoglandular hypothesis, which suggests that obstruction of the deep submucosal glands results in infection and abscess formation in the intersphincteric space, which consequently drains inferiorly between the sphincters, opening onto the skin surface or, less commonly, erodes through both the internal and external sphincters into the ischiorectal space, then onto the skin surface ¹."

Line 7:80 · More than 5 commas in a single sentence might make it more difficult to read.

Semicolons

suggestion

"the accuracy of Goodsall's rule has been debated, with some studies reporting predictive accuracy up to 75% for posterior fistulae; the accuracy for anterior fistulae is considerably lower ¹³"

Line 40:138 · Use semicolons judiciously.

There Is

suggestion

"The benefits of ultrasonography over MRI include its ubiquity and lower operating costs ⁸. There are three ultrasonography methods for the evaluation of perianal fistulae, whether cryptoglandular or Crohn disease-associated ⁹:"

Line 70:106 · Don't start a sentence with 'There are'.
