Medical personnel often use ‘fancy’ talk, and it should be discouraged. 
Examples:  “ology” refers to the study of something.  Thus, etiology, strictly is the study of cause and is not cause.  So, “The etiology of diabetes is ……” is bad.  Write, the “cause of diabetes is …….”

Similarly, “The patient’s symptomatology was/were headache, fever, nausea”  should be “The patient’s symptoms were headache, fever, nausea.” And “the methodology used in this paper were . . .” should be, “The methods used in this paper . . .”

Rather than “the findings were as follows “as follows:”  write, “The findings were” (colon should not be used at all).

“As described previously” usually is redundant. “As described” is adequate since “described” already is past tense.

“A total of” usually is unnecessary: “A total of 39 patients” should be, “Thirty-nine patients.”

“Suffer from” should be avoided.  Not the “patients suffered from diabetes,” rather, “The patients had diabetes.” “Patients were diagnosed with . . ” should be “The diagnosis of XXXX was made in the patients” or “The patients had the diagnosis of XXXX.”

“Show” or “did not show”  often is used incorrectly.  “Histologic fibrosis staging did not show any significant association with……” Better: “Histologic staging was not associated with . . .”

“Utilize” is over used; usually it should be “used.”

“Compared with” or “compared to” often is used incorrectly.  “A was bigger compared to B” should be “A was bigger than B.”

“In terms of” should be avoided. “In terms of complications, diabetes has more than gout.”  Change to “Diabetes has more complications than gout.”

Example of wordiness: “Measurements of blood glucose were conducted,” should be “blood glucose was measured,” or “the concentration of blood glucose was measured.”

“The patient has had 3 surgeries on his/her hip.” This is incorrect usage, which has become common in medical circles as well as in lay.  Surgery is a discipline; operation is the procedure.  “The patient has had three operations on his/her hip” is correct.  Use “operation” instead of “surgery” most often. For example: “Finished the surgery” is better written as, “finished the operation.”

Put a space between numerical value and unit, such as 23 g; not 23g.

Patients should not be referred to as “cases.” For example, “A case of hepatitis was treated” should be, “A patient with hepatitis was treated.” It is permissible, though, to refer to cases when not specifically referring to patients, such as “Our series consisted of 100 cases of hepatitis.”

“Data” is plural, although nowadays it often is used as singular. I prefer the plural usage, such as “The data were reviewed.”

Pay attention to the conventions for italicizing and capitalizing the names of microorganisms, such as bacteria and fungi.

“Criteria” is plural and “criterion” singular.

“Different” should not be used when “various” is intended. For example, “The drug induced many different reactions” should be the “drug induced various reactions.”

Avoid “etc.” It says nothing.

“Patients that have . . .” is better as “Patients who have . . .”

You can get rid of many “there is” or “there are” like this: “There is a growing number of births.” Replace with, “The number of births is increasing.” “There were 15 studies that assessed . . .” Replace with, “Fifteen studies assessed . . .”

Use of “by” is tricky. Example: “The publication biases were evaluated by Begg and Egger methods. Begg and Egger did not do the evaluation. Better: “The publication biases were evaluated with Begg and Egger methods.” Or, “The publication biases were evaluated by use of Begg and Egger methods.”

Usually the generic name of drugs is preferred over the trade name. (The trade name is always capitalized and the generic name is not.)

Et al. always has a period after al. because it is an abbreviation for et alia.

Hyphens are needed for terms such as 12 mm trocar. 12-mm trocar is correct
.
Expressions such as “. . . results in a reduction,” which are used ubiquitously, can be shortened to “. . . reduces.”

“Comparable” and “similar.” “Comparable” means that things can be compared. “Similar” means they are about the same. Example: Outcomes with the two treatments were similar–not comparable.

Avoid the double qualifier: “Findings suggest that A may be larger than B.” Better: “Findings suggest that A is larger than B.”
