Early in the course of acute appendicitis, are vital signs usually abnormal?✔✔no -
early in its course, vital signs including temperature may be normal. Once perforation
has occurred, the rate of low-grade fever (<38 C) increases to about 40%.

psoas sign = pain upon extension of the hip.#$/images/upload-

explain what rebound in the setting of acute appendicitis means✔✔Rebound is
usually elicited only after the appendix has ruptured or infarcted.
In establishing a differential diagnosis of abdominal pain, the onset of PAIN prior to
the occurrence of N/V is more often suggestive of✔✔surgical etiology of the pain,
such as small bowel obstruction
what bug should you think of in patients with sickle cell anemia who present with
abdominal pain and diarrhea?✔✔salmonella (not shigellosis)
Radiation of pain to the scapula is suggestive of✔✔acute choleycystitis (NOT
hepatitis)
Diverticulitis pain is generally located✔✔in the LLQ
Describe the pain patterns a/w with peptic ulcer disease (PUD)✔✔pain that is worse
preceding a meal
non-radiating, burning epigastric pain
pain that awakens a patient in the middle of the night
relief of abdominal pain with antacids
note: unrelenting pain over a period of weeks should suggest an alternative
diagnosis
,A 78 year old female presents to the E.D. with a sensation of LLQ abdominal pain,
accompanied by some irregular bowel movements and loss of appetite. Her
abdominal CT (two images) is shown in the Figure. What is the most likely
diagnosis?✔✔/images/upload-flashcards/601487/854531_m.jpg#$A patient with this
general picture is most likely to have diverticulitis, which is revealed on the CT scan
as diverticular disease with inflammation (wall thickening and
stranding).#$/images/upload-flashcards/601487/854534_m.jpg
A mother brings her 6 week old boy to the emergency room. She states the baby has
been vomiting everything she's tried to feed him for the past 12 hours. She states
that he usually eats readily and completes an entire feeding, but he is unable to keep
anything down. The emesis is non-bloody and non-bilious, however it is projectile in
nature. What is the most likely condition in this patient?✔✔pyloric stenosis
The answer is C. Hypertrophic pyloric stenosis typically presents in the second to
sixth week of life and is four times more common in males than females. Infants with
hypertrophic pyloric stenosis typically are vigorous eaters but shortly afterward
regurgitate the entire feeding contents in a projectile fashion. The emesis is non-
bilious. The classic finding on exam is an "olive" palpable in the abdomen, and
diagnosis is typically via ultrasound. Intussusception typically presents between the
ages of 5 and 12 months. Gastroenteritis is characterized by diarrhea as well as
vomiting. Neither constipation nor appendicitis typically present with protracted
vomiting, though the latter condition tends to present atypically in young children
(and elderly adults).
46yo F c/o abrupt onset of intermittent severe pain in L flank & abdomen that woke
her from sleep. She is pacing & appears extremely uncomfortable. She has never
experienced this type of pain previously and denies fevers or other symptoms. Renal
calculus is suspected. Some questions -
What is the best diagnostic test (KUB, IVP, Helical CT, U/S)?
How helpful is a Urinalysis?✔✔Helical CT scan is greater than 95% sensitive and
specific for renal calculi
Helical CT scan has been shown to be both highly sensitive and specific in the
diagnosis of renal calculi. It is the preferred modality for evaluation in many centers.
Although urinalysis typically demonstrates hematuria in patients with renal calculi,
hematuria is not specific enough to confirm the diagnosis, and imaging is warranted
in all first-time presenters. KUB detects approximately 60-70% of calculi (though
studies addressing this issue are somewhat methodologically flawed). Ultrasound is
not reliable for detecting small calculi, but is 85-94% sensitive and 100% specific at
demonstrating hydronephrosis. IVP is contraindicated in patients with renal
insufficiency due to the dye load necessary to perform the study.
50 yo M p/w 1 day of gradually worsening, intermittent, LLQ pain a/w loose stools.
No fevers or bloody bowel movements. Similar sxs in the past were self-limited. Vital
signs wnl. PE shows mild tenderness in LLQ, +BS and no masses or peritoneal
, signs. His PCP can see him tomorrow in his clinic. What should be done next in the
E.D.?✔✔Discharge home on high-fiber diet, laxatives and stool softeners
This patient has classic diverticulosis (saclike protrusions of colonic mucosa through
the muscularis) without signs of acute diverticulitis (inflammation of diverticula).
Usually these patients can be managed as outpatients with a high-fiber diet and
treatments to decrease intestinal spasm. If the patient develops fever or pain
increases he may need further evaluation to rule out abscess formation. Diverticulitis
is treated with antibiotics, bowel rest and analgesics.
You are treating a 25yoM with the recent diagnosis of Crohn's disease in the ED.
Regarding Crohn's disease, you know that:✔✔There is a small increased risk of
colon cancer
Although Crohn's disease may involve the entire bowel tract, the rectum is rarely
involved. Involved areas are typically non-contiguous (known as "skip lesions") and
the inflammation involves all of the layers of the bowel wall--resulting in many of the
complications of Crohn's such as abscess and fistula formation, intestinal
obstruction, and perforation. The risk of colon cancer is only slightly elevated above
baseline. In contrast, Ulcerative colitis begins in the rectum and may spread to the
upper parts of the colon but never involves the small intestine. The ulcerations are
contiguous and involve only the colonic mucosa. The incidence of colon cancer may
be increased up to 30 times over baseline.
53yo obese woman presents to ED, accompanied by three of her children, c/o
severe abdominal pain that began this afternoon after lunch. PE reveals marked
RUQ tenderness. Likely findings on this patient would include:✔✔This woman is
likely suffering from acute cholecystitis. Predisposing factors include female gender,
obesity, increased age and increased parity. Inflammation of the gallbladder causes
RUQ pain and sonographic Murphy's sign (inspiratory arrest, due to pain, while the
ultrasound probe is positioned over the gallbladder). Pain may radiate to the right
scapula. Lab studies usually show leukocytosis with or without a left shift, and
aminotransferases and bilirubin are usually within normal limits.
25yo F p/w epigastric pain radiating straight through to the back. Labs are notable
only for markedly elevated amylase and lipase. An abdominal X-ray is taken (see
Figure). What's the dx?✔✔/images/upload-flashcards/601487/924401_m.jpg#$The
most likely explanation for her symptoms is gallstone-related pancreatitis
The X-ray reveals stones in the gallbladder. These particular stones are not likely the
cause of pancreatitis, but the demonstration of gallstone disease raises the likelihood
that the patient's pancreatitis is indeed due to gallstones. In the U.S., the most
common etiologies of pancreatitis include gallstones (45%) and alcoholism (35%).
Alcoholic pancreatitis may occur in young patients as well as in older abusers of
alcohol. Many other drugs, infectious agents, and conditions are associated with the
development of pancreatitis. A few examples include hypertriglyceridemia, trauma,
pregnancy, pancreatic carcinoma, atherosclerotic emboli, and scorpion bites.
