Principles of Diagnosis Construction
Medical diagnoses can be expressed as multi-word terms (e.g., Carcinoma ventriculi — gastric cancer) or formed by combining term elements. When translating Russian clinical diagnoses into Latin, it is important to consider the grammatical relations between nouns and adjectives.
There are various groups of multi-word terms:
- Purely Latin constructions, for example, Abscessus retropharyngeus (retropharyngeal abscess) or Glaucoma posttraumaticum (post-traumatic glaucoma).
- Mixed clinical terms combining Latin and Greek roots: Anaemia posthaemorrhagica (posthemorrhagic anemia) or Infarctus myocardii (myocardial infarction).
Tumors and Fluid Accumulations
A significant portion of diagnoses describe neoplasms or pathological accumulations of various substances.
The suffix -oma is used to denote tumors:
- Hidradenoma — a tumor of the sweat glands.
- Thymoma — a tumor of the thymus gland.
- Lipoma — a benign tumor of adipose tissue.
Pathological fluid accumulations are formed using the corresponding roots:
- Pus (pyo-): Pyoperitoneum (pus in the peritoneal cavity).
- Blood (haemo-): Haematotympanum (blood in the tympanic cavity).
- Combined: Pyohaemopericardium (accumulation of pus and blood in the pericardial cavity).
Inflammatory Processes and Membranes
Inflammatory diseases are traditionally designated by the suffix -itis. At the same time, the localization of inflammation relative to membranes or surrounding tissues is often specified using the prefixes endo-, peri-, para-.
Examples:
- Endocarditis — inflammation of the inner lining of the heart.
- Paraproctitis — inflammation of the tissue surrounding the rectum.
- Gastroenteritis — combined inflammation of the stomach and small intestine.
- Vasculitis — inflammation of blood vessels.
These same prefixes are used to name the membranes themselves: Endometrium (inner lining of the uterus), Perimetrium (serous membrane), Parametrium (parametrium / pelvic cellular tissue around the uterus).
Functional Disorders and Methods
Specific CFs are used to describe functional failures and diagnostic methods. Disorders often begin with the prefix dys- (difficulty, disorder) or a- / an- (absence):
- Dysphagia — difficulty swallowing.
- Dyspnoea — shortness of breath.
- Anhidrosis — absence of sweating.
- Adynamia — muscular weakness.
Instrumental and diagnostic methods use the roots -metria (measurement) and -graphia (radiography or recording):
- Sphygmometria — pulse measurement.
- Cholangiocinematographia — cholangiocinematography.
Briefly: answers to topical questions
How are the names of benign and malignant tumors distinguished in Latin terminology?
In Latin terminology, the general nomenclature of mesenchymal tumors is built on a single principle: benign neoplasms are designated by the root of the tissue of origin with the addition of the suffix -oma, for example, fibroma, lipoma, chondroma, or osteoma. Malignant tumors of the same histogenetic line are called sarcomas. Meanwhile, malignant epithelial tumors are called cancer or carcinoma. Benign tumors possess only tissue atypia, whereas malignant ones are characterized by tissue and cellular atypia, infiltrative growth, and predominantly produce hematogenous metastases.
Which term elements denote surgical operations such as removal, incision, or creation of a fistula?
Special Greek combining forms are used in clinical terminology to denote various surgical interventions. The operation of incision, opening of an organ or tissue is designated by the suffix -tomia. The surgical operation of removing or excising an organ or tissue is designated by the suffix -ectomia. The creation of an artificial opening, stoma, fistula, or anastomosis between organs is designated by the suffix -stomia.
Which Greek term elements are used to denote various types of pain?
Greek combining forms and suffixes are used in medical terminology to denote pain and painful sensitivity. The first element alg- together with the suffixes -algia and -algesia denotes painful sensitivity or pain. Another combining form used to denote pain is -odynia.
To easily remember organ membranes, use the 'EPP' rule: Endo- (inside, like an endoscope), Peri- (around the organ itself, like a perimeter), Para- (near, in the surrounding tissue). For example: endometrium, perimetrium, parametrium.
Class and exam questions
What is the difference between ischemia and ischuria?
Ischaemia is blood stasis or local anemia, while ischuria is urine retention. The common root isch- means retention, obstruction.
How to translate 'disease of the thymus gland'?
The term Thymopathia is used, where thymo- is the thymus gland and -pathia is a disease.
What does the suffix -lysis mean in blood-related terms?
The suffix -lysis means destruction or breakdown. For example, haemolysis is the destruction of red blood cells, thrombocytolysis is the destruction of platelets.
