◉ Aspirin use.
Answer: Reye syndrome in children has been associated with aspirin
administration during viral illnesses.
◉ IgM.
Answer: IgM anti-HAV rises early in acute hepatitis A infections.
◉ Hepatitis Core antibody.
Answer: After about a year, the IgG core antibody (anti-HBc)
typically remains positive in ongoing or past HBV infection.
◉ Antinuclear antibody.
Answer: ANA testing is the primary screening test for SLE.
◉ Apocrine.
Answer: Apocrine sweat gland obstruction (e.g., in hidradenitis
suppurativa) often leads to abscess formation.
,◉ Irregular border.
Answer: An irregular or poorly demarcated border is a classic red
flag for melanoma.
◉ Actinic keratosis.
Answer: Actinic (solar) keratoses are considered premalignant
lesions from sun (UV-B) damage.
◉ Diameter of 0.8 cm.
Answer: Lesions >6 mm (0.6 cm) in diameter are concerning ("D" in
ABCDE). At 0.8 cm, it's suspicious.
◉ GABA.
Answer: Alcohol enhances GABA; withdrawal states lead to relative
GABA deficiency, causing hyperadrenergic symptoms.
◉ TSH and free T4.
Answer: Thyroid function tests help rule out hyperthyroidism, which
can mimic anxiety symptoms.
◉ Olfactory.
Answer: Perceiving nonexistent odors is an olfactory hallucination.
,◉ Depression.
Answer: Depression is the most frequent psychiatric condition co-
existing with self-harm/suicidality.
◉ Damage to the rotator cuff.
Answer: Pain on overhead abduction or arm raise commonly
indicates rotator cuff pathology.
◉ Temporomandibular joint (TMJ) pain.
Answer: TMJ issues cause jaw pain, limited mouth opening, and
often benefit from bite guards.
◉ Ankylosing spondylitis.
Answer: Sacroiliitis plus decreased lumbar mobility is classic for
ankylosing spondylitis.
◉ Trigeminal nerve.
Answer: The trigeminal nerve (CN V) provides facial sensory
innervation.
◉ Snellen chart for visual acuity.
Answer: CN II (optic nerve) is assessed with visual acuity (Snellen)
and visual fields.
, ◉ Stereognosis.
Answer: Stereognosis tests the ability to perceive and identify
objects by touch alone.
◉ Impaired gag reflex.
Answer: CN IX provides sensory input for the gag reflex.
◉ Hematuria with RBC casts.
Answer: Diagnosis confirmed after a patient successfully treated for
strep infection.
◉ Glomerulonephritis.
Answer: RBC casts post-strep are classic for acute post-streptococcal
glomerulonephritis.
◉ WBC casts on urinalysis.
Answer: WBC casts indicate upper urinary tract infection
(pyelonephritis).
◉ Renal punch test.
Answer: Costovertebral angle tenderness ("renal punch") is classic
for pyelonephritis.
