UPDATE: We will discontinue using quotation marks to identify parts of an article, but retain the capitalization; eg, This is discussed in the Methods section (not the “Methods” section). This change was made February 14, 2013. What would become of us if the deleatur did not exist, sighed the proofreader.    José Saramago We not infrequently are compelled to refuse publication to an article which contains valuable facts, but which is weighed down with so many imperfections as to discourage one as does the porcupine from closer investigation.     JAMA The second quote, from a 1904 editorial in JAMA, certainly holds true today, but Less

Back-formation is the creation of a new word in the mistaken belief that it was the source of an existing word. Many back-formations are verbs, some of them derived from abstract nouns (ambulate from ambulation, diagnose from diagnosis, dialyze from dialysis) and others from agent nouns, real or supposed (beg from beggar, peddle from peddler, scavenge from scavenger). These examples of back-formations have achieved acceptance; however, many of those pertaining to medical jargon have not, including adhese, cyanose, defervesce, diurese, lyse, necrose, pex (from orchidopexy), plege (from cardioplegia), and torse. Medical jargon also includes many deviant singular forms of nouns Less

Many words have found their way into medical vocabularies with unusual meanings that are not recognized even by medical dictionaries. Such writings may be characterized as medical jargon or medical slang. When these words appear in medical manuscripts or in medical conversation, they are unintelligible to other scientists, particularly those of foreign countries; they are not translatable and are the mark of the careless and uncultured person.   Morris Fishbein, MD I have laboured to refine our language to gram- matical purity, and to clear it from colloquial barbarisms, licentious idioms, and irregular combinations.  Samuel Johnson (1709 1784) Words and phrases that can Less

They may also be referred to as teenagers or as adolescent boys or adolescent girls, depending on context. Adults Less

Authors often err in referring to anatomic regions or structures as the “right heart,” “left chest,” “left neck,” and “right brain.” Generally these terms can be corrected by inserting a phrase such as “part of the” or “side of the.” right side of the heart; right atrium; right ventricle left side of the chest; left hemithorax left aspect of the neck right hemisphere [query author] ascending [not right] and descending [not left] colon Where appropriate, use specific anatomic descriptors: The upper extremity comprises the arm (extending from the shoulder to the elbow), the forearm (from the elbow to the wrist), Less

Occasionally, reference to a locus of insertion, position, or attitude is given in terms of a clock-face orientation, as seen by the viewer (see also , Numbers and Percentages, Use of Numerals, Measures of Time). Note: The terms clockwise and counterclockwise can also be confusing. The point of reference (eg, that of observer vs subject) should be specified if the usage is ambiguous. | Less

Usually, in reports of clinical or laboratory data, the substance per se is not reported; rather, a value is given that was obtained by measuring a substance or some function or constituent of it. For example, one does not report hemoglobin but hemoglobin level. Some other correct forms are as follows: differential white blood cell count agglutination titer prothrombin time pulse rate erythrocyte sedimentation rate total serum cholesterol value or level or concentration increase in antibody level creatinine level or clearance serum phosphorus concentration increase in bilirubin level platelet count 24-hour urine output or volume antinuclear antibody titer mean corpuscular Less
