Acronyms

warning

"Fibrous dysplasia accounts for the "F" in the popular mnemonic for lucent bone lesions FEGNOMASHIC."

Line 2:94 · 'FEGNOMASHIC' has no definition. Spell it out if it's unfamiliar to the audience.

"evidence of GNAS activating missense mutations"

Line 20:28 · 'GNAS' has no definition. Spell it out if it's unfamiliar to the audience.

"With sensitive methods, GNAS activating missense mutations, which normally encode the alpha subunit of the stimulatory G-protein, can be detected in the majority of cases (~64-83%) ¹⁸, particularly those involving pArg201His and pArg201Cys ^1,4. However, the detection rate depends heavily on the sensitivity of the molecular technique used and the proportion of mutant cells in the sample."

Line 72:28 · 'GNAS' has no definition. Spell it out if it's unfamiliar to the audience.

"aneurysmal bone cyst: Fibrous dysplasia and ABC can coexist in the same bone, and some literature shows fibrous dysplasia developing into ABC"

Line 89:52 · 'ABC' has no definition. Spell it out if it's unfamiliar to the audience.

"aneurysmal bone cyst: Fibrous dysplasia and ABC can coexist in the same bone, and some literature shows fibrous dysplasia developing into ABC"

Line 89:146 · 'ABC' has no definition. Spell it out if it's unfamiliar to the audience.

"If features are typical, the lesion can be categorised as Bone-RADS 1 on CT or MRI ⁶."

Line 178:70 · 'RADS' has no definition. Spell it out if it's unfamiliar to the audience.

warning

"aneurysmal bone cyst: Fibrous dysplasia and ABC can coexist in the same bone, and some literature shows fibrous dysplasia developing into ABC"

Line 89:28 · The first word after a colon should almost always be lowercase. In this case, it's not: ': Fibrous dysplasia'.

There Is

suggestion

"Fibrous dysplasia is uncommon, occurs in children and adults and can affect all age groups ^1,2. It is usually first diagnosed in children and young adults. The true incidence is not known, but it is estimated to account for ~5% of benign bone lesions ^3,4. There is no gender predilection ¹."

Line 7:282 · Don't start a sentence with 'There is'.

Semicolons

suggestion

"Mazabraud syndrome: soft-tissue myxomas (rare); typically multiple intramuscular lesions in the vicinity of most severely affected bone"

Line 88:61 · Use semicolons judiciously.

Oxford Comma

suggestion

"Fibrous dysplasia was first described by the American bone pathologist Louis Lichtenstein in 1938, and the clinical, radiological and histological spectrum of findings was later characterised by him and his colleague Henry Louis Jaffe in 1942 ^13,14."

Line 187:111 · Use the Oxford comma in 'clinical, radiological and histological'.
