the Names

Medical Definition
  • Name(s) of one or more individuals who devised

    meaning is different from that which was
    described the eponym has no historical basis.
    Mark M. Ravitch, MD

Eponyms in the Medical Literature
  • 1974 US National Institutes of Health conference
    held on the naming of diseases
  • JAMA published an article vowing to drop the
    possessive s (Archer J. Epitomes. JAMA 234152,
    1975) but journal editors over the years have
    been divided

7
Types of Eponyms
  • Named after male physicians (2,880 on
    whonamedit.com)
  • Named after female physicians (101)
  • First and last name
  • Austin Flint
  • Named after more than one person
  • Charcot-Marie-Tooth-Hoffman disease
  • Named after famous people with the disease
  • Lou Gerhig
  • Named after fictional characters

Case 1 Crohns Disease
  • Subacute chronic enteritis involving the terminal
    ileum and other parts of the GI tract (lips to
    anus), characterized by patchy, deep ulcers that
    may cause fistulas, with noncaseating granulomas
  • Symptoms include fever, diarrhea, cramping,
    abdominal pain and weight loss
  • Distinguished from UC because inflammation is
    transmural, and presence of skip lesions

Colonic ulceration in Crohns

Our Story Begins at Mt. Sinai Hospital in NYC, in
1930
11
Granulomas of Crohns were thought to be of an
infectious etiology

Case 2 Pickwickian Syndrome
  • Syndrome of hypoventilation and hypercapnia
    resulting in daytime somnolence, pulmonary
    hypertension and occasionally, polycythemia
  • Cause Extreme obesity

15
1837 Charles Dickens wrote The Posthumous Papers
of the Pickwick Club
16
Literary Origin (and the modern-day version)
  • A most violent and startling knocking was heard
    at the doorThe object that presented itself to
    the eyes of the astonished clerk was a boy- a
    wonderfully fat boy- habited as a serving lad,
    standing upright on the mat, with his eyes closed
    as if in sleep. He had never seen such a fat boy,
    in or out of a traveling caravan and this,
    coupled with the calmness and repose of his
    appearance, so very different from what was
    reasonably to have been expected in the inflictor
    of such a knock, smote him with wonder. Whats
    the matter? inquired the clerk. The
    extraordinary boy replied not a word but he
    nodded once, and seemed, to the clerks
    imagination, to snore feeblyHe breathed heavily,
    but in all other respects was motionless. The
    clerk repeated the question thrice, and receiving
    no answer, prepared to shut the door, when the
    boy suddenly opened his eyes, winked several
    times, sneezed once, and raised his hand as if to
    repeat the knocking. What the devil do you knock
    in that way for? inquired the clerk, angrily.
    Because master said, I wasnt to leave off
    knocking till they opened the door, for fear I
    should go to sleep, said the boy.

119 Years Later
  • Extreme Obesity Associated with Alveolar
    Hypoventilation A Pickwickian Syndrome by CS
    Burwell, et al., 1956
  • Described a 51-year-old business executive who
    stood 55 and weighed over 260 lbs.

18
Case 3 Brugada Syndrome
  • Right bundle branch pattern with ST elevation
    from V1-V3
  • Associated with sudden cardiac death in young
    people without structural heart disease and a
    negative stress test
  • Often associated with syncope, VF/VT

19
Evolution of the Syndrome
  • 1953 Drs. Osher and Woff noted the
    characteristic EKG pattern, and considered it a
    normal variant
  • 1980s CDC in Atlanta noted a high incidence of
    young Thai immigrants dying of sudden cardiac
    death. In Thailand, this frequent condition was
    known as Lai Thai (death during sleep). Later
    this population would be found to have high
    frequencies of the mutation associated with
    Brugada.

20
  • 1986 Pedro Brugada treats a male Polish child
    with syncope whose sister died of sudden cardiac
    death.
  • With brother Josep, collected more cases of this
    characteristic EKG and its association with
    sudden cardiac death in young people

21
  • 1992 Brugada brothers, from Catalonia, Spain,
    describe the entity
  • 1998 Specific gene mutations in the Na-ion
    channels found to be responsible for the
    characteristic depolarization seen on EKG and the
    incidences of sudden death with no structural
    heart disease.

22
Francois Gigot de la Peyronie (1678-1747)
23
Case 4 Peyronies Disease
  • In a treatise on ejaculatory failure in 1743,
    Peyronie described a patient with rosary beads
    of scar tissue along the dorsum of his penis
  • Resulted in a curvature in the erect penis

24
  • Due to a connective tissue disorder of plaque
    formation in the corpora cavernosa
  • Affects .3-3 of men 40-60 years old
  • Can cause penile pain
  • 50 of cases spontaneously regress
  • Usually initiated by penile trauma during
    intercourse, resulting in plaque formation

25
Peyronie gets the eponym, but
  • First described in 1587 by Giulio Casare Aranzi,
    a Bolognese anatomist
  • Thought to be punishment for incest, since the
    Byzantinian Emperor Heracles, who took his niece
    for his wife, was said to have developed a penile
    deformity that caused him to urinate into his
    face

26
  • 1942 review article speculated when a youth is
    addicted regularly to sessions of prolonged
    ungratified sexual desires, his prostate, being
    in a constant state of engorgement, will develop
    prostatic hypertrophy and result in Peyronies
    disease
  • Also cited frigid female partners, giving as
    evidence one man whose condition resolved after
    his wife became more amorous.

27
Treatment
  • If treatment of the plaque with iodides is
    unsuccessfulor if the condition progressesthen
    the whole penis must promptly be amputated
  • William J. Walsham, MD
  • London surgeon, 1903
  • Vitamin E, various surgical techniques,
    straightening braces

Case 5 Barretts Oesophagus
  • Change of the esophageal lining from squamous to
    columnar (which is found in the stomach)
  • Thought to be a complication of severe GERD
  • Risk factor for esophageal cancer (metaplasia)

30

31
  • Norman Barrett, an Australian surgeon, was the
    first to recognize these changes
  • However, he believed they occurred because these
    patients had a congenitally short esophagus, and
    the stomach had intruded into the chest to
    compensate
  • Dr. Jean-Louis Lortat-Jacob, a French surgeon,
    discovered the abnormalities around the same time
    as Barrett, and he correctly hypothesized that it
    was an acquired lesion
  • However, his paper was written in French.
    Barrett wrote his in English. The rest is
    history.

32
Eponyms Etiquette
  • It is poor form to name something after yourself
  • Follow the lead of Fred Askin Make a long name
  • Described a Small round blue cell tumor of the
    thoraco-pulmonary region.
  • The next paper referred to small round blue cell
    tumor of the thoraco-pulmonary region (Askins
    disease)
  • Now simply known as Askins disease

33
Tashimas Syndrome
  • CK Tashima (JAMA 1942081965) identified
    Tashimas Syndrome
  • A physicians search for a new sign, disease or
    syndrome to attach his name to.
