Whonamedit? is an online English-language dictionary of medical eponyms and the people associated with their identification. [1] Though it is a dictionary, many eponyms and persons are presented in extensive articles with comprehensive bibliographies. [1] The dictionary is hosted in Norway and maintained by medical historian Ole Daniel Enersen. [2]
An eponym is a person, a place, or a thing after whom or which someone or something is, or is believed to be, named. The adjectives which are derived from the word eponym include eponymous and eponymic.
Inguinal lymph nodes are lymph nodes in the groin. They are situated in the femoral triangle of the inguinal region. They are subdivided into two groups: the superficial inguinal lymph nodes and deep inguinal lymph nodes.
In the fetus, the ductus venosus shunts a portion of umbilical vein blood flow directly to the inferior vena cava. Thus, it allows oxygenated blood from the placenta to bypass the liver. Compared to the 50% shunting of umbilical blood through the ductus venosus found in animal experiments, the degree of shunting in the human fetus under physiological conditions is considerably less, 30% at 20 weeks, which decreases to 18% at 32 weeks, suggesting a higher priority of the fetal liver than previously realized. In conjunction with the other fetal shunts, the foramen ovale and ductus arteriosus, it plays a critical role in preferentially shunting oxygenated blood to the fetal brain. It is a part of fetal circulation.

Mendelson's syndrome, named in 1946 for American obstetrician and cardiologist Curtis Lester Mendelson, is a form of chemical pneumonitis or aspiration pneumonitis caused by aspiration of stomach contents during anaesthesia in childbirth. This complication of anaesthesia led, in part, to the longstanding nil per os recommendation for women in labour.

The straight leg raise is a test that can be performed during a physical examination, with the leg being lifted actively by the patient or passively by the clinician. If the straight leg raise is done actively by the patient it is a test of functional leg strength, particularly the rectus femoris element of the quadriceps. If carried out passively, it is used to determine whether a patient with low back pain has an underlying nerve root sensitivity, often located at L5. The rest of this article relates to the passive version of the test.

Dittrichin Siegmundin was a German obstetrician named as a possible re-inventor of nooses and blunt hooks for turning or extracting an infant in difficult births. She was the first, along with Francois Mauricaeu, to apply the technique of puncturing the amniotic sac to arrest hemorrhaging in placenta praevia. During this time, she studied the correct amount of use of these tools and wrote about the importance of not overusing or abusing these tools and procedures. She studied the instruments and procedures of obstetrics from books and practice alongside peasant women for nearly 12 years. In 1689 her first book was published, and reprinted six times, for midwives reflecting on all of the notes and illustrations she kept with each delivery in her practice. She eventually became the midwife to the Court of the Elector of Brandenburg in the royal family of Prussia and one of the most celebrated of the German midwives of the 17th century.
