A 50-year-old man
presents to your office with severe
discomfort in the great toe that began
24 hours earlier. He denies any trauma
but says that he may have had
similar symptoms many years before.
He has no recent history of fever
or illness. You aspirate fluid from the
first metatarsophalangeal joint for
A 41-year-old woman has had a 2-week bout of nausea, vomiting, and diarrhea.
Her history includes chronic hepatitis C and alcohol abuse. She also has orthostatic
hypotension. A baseline ECG is obtained.
For 2 months, a 47-year-old woman experienced constipation, weakness, fatigue, and dry skin. She also complained of moderate weight gain and menorrhagia during the same period. The patient took no medications and denied any allergies.
A 42-year-old woman complains of anxiety, unexplained weight loss, and palpitations
that started about 3 weeks earlier. She denies fever, trauma, and new
stress. She has a history of several urinary tract infections for which imaging
failed to reveal any predisposing factors; all were successfully treated with
medication. The remainder of the history is unremarkable.
After exposure to the sun, an erythematous, edematous, pruritic allergic
reaction developed at the site of a 22-year-old man’s new tattoo. In addition
to photoallergy—as seen in this patient—direct allergy to the dyes in the
tattoo can produce an adverse reaction.
Postoperative inflammation occurred shortly after this
25-year-old woman’s earlobes were pierced. Within a few
months, bilateral keloids developed at the sites. The
keloid on the left ear is shown here.
Primary care providers are seeing
an increasing number of
patients who have snakes or
barbwire coiling around their
arms or gold rings dangling
from their eyebrows and navels. Tattooing
and body piercing are particularly
popular among adolescents and
young adults—many of whom may not
be aware of the possible medical complications
of these ancient practices.
Also known as congenital aganglionic megacolon (A), this condition is characterized by a congenital absence of ganglion
cells in the submucosal (Meissner) plexus and the
myenteric (Auerbach) plexus in one or more segments of
the colon. This is attributable to a failure of migration of
nerve cell elements from the neural crest in a cephalocaudal
direction along the GI tract. The absence of parasympathetic
innervation causes failure of relaxation of the internal
anal sphincter. An aganglionic colon does not permit
normal peristalsis to occur and thus results in a
