Wood’s Lamp

 

Other Known Aliases – Ultraviolet (UV)-A lamp, blacklight

Definition – Handheld UV light that emits UV-A (long-wave) light with a violet filter, which blocks most of the visible light, and only allows the UV-A through

Clinical Significance – There are many medical applications for using UV light for quick, bedside diagnosis.  One of these is for fungal infections of the skin, most commonly Tinea infections.  Tinea infections will fluoresce under UV-A light.

History – Named after Robert W. Wood (1868-1955), who was an American physicist, inventor, and a pioneer in infrared and ultraviolet photography.  In 1903, he developed a filter that would block visible light, but be transparent to both infrared and ultraviolet light.  He won several awards and honors in the field of optics (he even has a crater on the moon named after him) and is the namesake of the R.W. Wood Prize of the Optical Society of America, which recognizes outstanding discovery, achievement, or invention.

Ishihara Test

 

Other Known AliasesPseudo-isochromatic plates

DefinitionTest for detecting color blindness using different color dots to outline numbers

Ishihara 9.png

Clinical SignificanceAllows for quick assessment of color blindness using different styles plates (a full test is 38 plates) and even differentiate between different types of color blindness.  Research has proven that a score of 12 out of 14 red/green plates indicates normal color vision with a sensitivity of 97% and a specificity of 100%.

History – Named after Shinobu Ishihara (1879-1963), who developed these while working as a military surgeon for the Japanese army during World War I as a better way of assessing color blindness in troops.  He first published these findings in 1917 in Japan and it was first translated and reviewed in the American Journal of Ophthalmology in June 1918 extolling its usefulness.

History – Named after Franz Kasper Hesselbach (1759-1816), who was a German physician, surgeon, and anatomist in Hammelburg, Germany.  He had a prolific career surgical assistant and prosector under Karl Kasper von Siebold at The Juliusspital in Würberg, before obtaining his doctor of medicine there.  He is best known for his contributions to the surgery of hernias and has several other eponyms as well: Hesselbach’s fascia (cribriform fascia) and Hesselbach’s ligament (interfoveolar ligament.

Murphy’s Sign

 

Other Known AliasesMoynihan’s Method (using just the thumb with patient supine)

DefinitionInspiratory arrest with deep palpation in the right upper quadrant 

Clinical SignificanceAs the patient exhales, the abdominal organs move cephalad and under the diaphragm.  After full exhalation and during inspration, the organs move caudal back into the abdominal cavity.  When there is inflammation of the gallbladder, the patient will stop inhaling as the inflammed gallbladder touches the practitioner’s fingers during deep palpation of the right upper quadrant.

History – Named after John Benjamin Murphy (1857-1916), who was an American surgeon and early pioneer for many different surgical operations and techniques.  In fact, William James Mayo (co-founder of The Mayo Clinic) called him “the surgical genius of our generation”. 

In 1889, he advocated for and popularized early appendectomy in all suspected appendicitis cases and had over 200 successful cases to begin convincing his colleagues of the benefits of early surgery.  Dr. Murphy also pioneered treatment of tuberculosis with iatrogenic pneumothoraces and was the first surgeon to re-anastomose a transected femoral artery from a gunshot wound.  He was also a distinguished teacher and developed “wet clinics” at Mercy Hospital, where he operated and lectured to an audience of learners in a traditional operative theater.

Dr. Murphy also attended to Theodore Roosevelt after an assassination attempt and was one of the founding members of the American College of Surgeons.  He is also the author of one of the more famous quotes pertaining to patient-centered care.

Littre’s Hernia

 

Other Known Aliasesnone

DefinitionHernia involving a Meckel’s diverticulum 

Clinical SignificanceNo real clinical significance other than it is an extremely rare type of hernia, but is always included in the typical pimping barrage of surgery students.  It should also be included in the “zebras” of differential diagnoses of RLQ pain.

History – Named after Alexis Littrè (1654-1726), who was a distinguished physician and prolific surgeon at the historic Salpêtriére Teaching Hospital in Paris.  He was inducted into the famed Académie des Sciences in part to his ridiculous dissection of over 200 cadavers in 1684.  He first described an femoral hernia involving an intestinal diverticulum in 1700 in one of his cadaver dissections.

Other Known Aliasesnone

DefinitionVestigial remnant of the omphalomesenteric duct

  • 2% of these will be symptomatic by age 2
  • 2 types of heterotopic tissue
