Local signs of a traumatic spleen

"DOKS"
  • Debelt's sign
  • O'Connel's sign
  • Kehr's sign
  • Saegesser's sign

Or, "SKODa"


O'Connel's sign: It is Kehr's sign elicited with patient in Trendelenburg position. As it is usually becomes positive before the Kehr's sign, it is at times recommended to elicit O'Connel's sign as well.
Kehr's sign: Pain in the left shoulder caused by irritation of the undersurface of the diaphragm by blood leaking from a ruptured spleen. The pain impulses are referred along the phrenic nerve.
Saegesser's sign: Compression of phrenic point (along the border of the sternocleidomastoid muscle, 2-4 cm above the clavicle) causes sudden contraction of homolateral hemidiaphragm and severe pain along the lateral border of rectus abdominis muscle. It indicates a rupture or intracapsular bleeding of the spleen.

Genu valgum vs. genu varum

Genu valGUM (knock-knee): knees are GUMmed together.
· Varum (bowleg) is the other by default, or Far rhymes with Var, so knees are far apart.

Immunoglobulins -Order of appearance

'IMmunoGlobulin'
IgM appears first in response to antigens followed by IgG.
IgM antibodies appear early in the course of an infection and usually reappear, to a less extent, after further exposure. IgM antibodies cannot pass through human placenta. These two biological properties of IgM make it useful in the diagnosis of infectious diseases. Demonstrating IgM antibodies in a patient's serum indicates recent infection, or in a neonate's serum indicates intrauterine infection (e.g. congenital rubella).

 " ARP "

The acronym ARP can stand for  'accomodation reflex present'.
Thus in Argyll Robertson pupil (ARP) , accomodation reflex (near reflex) is present but light reflex is absent.
