MULTIPLE CHOICE

 

  1. Transmembrane adhesive heterodimeric proteins, composed of an a and a ß chain, are expressed on activated leukocytes during inflammation. They bind primarily to intercellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule 1 (VCAM-1), both of which belong to the family of proteins known as
  2. selectins
  3. integrins
  4. immunoglobulins
  5. lectins
  6. growth factors

 

ANS: C, Surface proteins expressed on activated leukocytes are integrins, and they bind to intercellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule 1 (VCAM-1), which belong to the immunoglobulin family of proteins.

 

  1. Which of the following mediators of inflammation has chemotactic properties and is increased in persons taking aspirin?
  2. Thromboxane A2
  3. Prostaglandin E2
  4. Platelet-activating factor
  5. Leukotriene B4
  6. Interleukin-1

 

ANS: D, Leukotriene B4 is chemotactic. It is increased in persons who take aspirin, because aspirin inhibits the cyclooxygenase pathway, thus shunting more arachidonic acid early derivatives into the lipoxygenase pathway. This promotes the synthesis of leukotrienes.

 

  1. A 2-year-old child known to suffer from recurrent bacterial infections and poor wound healing was found to have leukocyte adhesion molecule deficiency 1 (LAD-1). The leukocytes of this patient do not express CD18, a molecule classified as belonging to the family of
  2. selectins
  3. integrins
  4. lectin type of vascular adhesion molecules
  5. aminotransferases
  6. glycosidases

 

 

ANS: B, LAD-1 is characterized by a deficiency of CD18, a cell surface molecule that is a ß2 integrin. The infections occur because the defective leukocytes cannot adhere to endothelial cells, cannot spread and attach, and cannot phagocytose bacteria. PBD7 62

 

  1. Bradykinin is produced from a high-molecular weight kininogen circulating in the blood. This reaction is mediated by
  2. coagulation factor X
  3. kallikrein
  4. Hageman factor
  5. complement C3
  6. protein C

 

ANS: B, Kallikrein promotes the formation of bradykinin from the high-molecular weight kininogen. PBD7 67

 

  1. Nitric oxide synthesis is augmented in endothelial cells by a calmodulin-mediated influx of which element?
  2. Calcium
  3. Sodium
  4. Potassium
  5. Oxygen
  6. Nitrate

 

ANS: A, Endothelial cell nitric oxide synthase is constitutively expressed at low levels, but it can be increased by a calmodulin-mediated influx of calcium into the endothelial cells. PBD7 72

 

  1. Which of the following mediators of inflammation causes pain?
  2. Nitric oxide
  3. Complement C3a
  4. Bradykinin
  5. Leukotriene B4

  1. Aspirin lowers the body temperature by inhibiting the synthesis of which regulator of the central thermostat in the hypothalamus?
  2. Leukotriene B4
  3. Lipoxin
  4. Thromboxane A2
  5. Prostacyclin
  6. Prostaglandin E2

 

ANS: E, Aspirin inhibits the action of cyclooxygenase, and thus inhibits the synthesis of thromboxane A2, prostacyclin, and prostaglandin E2. However, only prostaglandin E2 is involved in thermoregulation. The synthesis of lipoxin and leukotrienes is not inhibited by aspirin. PBD7 70

 

  1. C-reactive protein binds to the surface of microbes in tissues acting as a(n)

  1. Most gastric polyps are microscopically classified as
  2. tubular adenomas
  3. villous adenomas
  4. hyperplastic polyps
  5. fundic gland polyps
  6. carcinoids

 

ANS: C, In 90% of cases, gastric polyps are non-neoplastic and are microscopically classified as hyperplastic polyps.

  2. Whipple disease
  3. celiac sprue
  4. tropical sprue
  5. lactase deficiency
  6. abetalipoproteinemia

 

ANS: B, Anti-endomysial and anti-gliadin antibodies strongly suggest a malabsorption syndrome that is caused by celiac sprue.

  2. jejunum
  3. ileum
  4. cecum
  5. transverse colon
  6. rectum

 

ANS: C, Angiodysplasia is most often located in the cecum, probably because the cecum has the widest diameter. The mechanism of formation of angiodysplastic lesions is not known. It is thought that the cecum, as the most dilated part of the colon, generates the highest pressure on intramural blood vessels, thus causing their tortuosity and dilatation that predisposes to rupture.

  2. Celiac disease
  3. Whipple disease
  4. Crohn disease
  5. Abetalipoproteinemia
  6. AIDS

 

ANS: A, Most likely this man had celiac sprue, a disease associated with a disproportionately high incidence of T-cell lymphomas.

 

  1. A 60-year-old man who complained of persistent right lower quadrant pain underwent an appendectomy. The appendix appeared globular and dilated due to an obstruction by a fecalith. It was filled with mucus. Histologically, the cavity was lined with normal appendiceal mucosa; there was no evidence of neoplasia. This lesion most likely represents a
  2. mucocele
  3. mucinous cystadenoma
  4. mucinous cystadenocarcinoma
  5. pseudomyxoma peritonei
  6. pseudocyst

 

ANS: A, A mucocele is a dilatation of the appendix in which the lumen of the appendix is filled with mucus. It results from an obstruction of the appendix by a fecalith or chronic inflammation, and less often by tumors.

 

 

  1. Primary tumors of the peritoneum are called
  2. adenocarcinomatosis peritonei
  3. pseudomyxoma peritonei
  4. peritoneal sarcoma
  5. mesothelioma

  1. adenocarcinoma
  2. squamous cell carcinoma
  3. transitional cell carcinoma
  4. basal cell carcinoma
  5. oat cell carcinoma

 

ANS: A, The squamo-columnar line in this esophagus is a few centimeters above the normal gastroesophageal junction, suggesting that the terminal esophagus has undergone metaplasia into a Barrett esophagus. Tumors originating in Barrett esophagus are typically adenocarcinomas.

 

  1. This slide shows the muscle layer of a stomach that was removed from a 60-year-old man who complained of dyspepsia and bleeding. The tissue section was taken from the muscle underneath a large prepyloric ulcer. Which of the following is the most likely diagnosis?

 

 

  1. Peptic ulcer disease
  2. Helicobacter pylori-related gastritis
  3. Autoimmune gastritis
  4. Hyperplastic gastropathy
  5. Adenocarcinoma

 

ANS: E, The muscle layer of this stomach is infiltrated with adenocarcinoma cells forming irregular tubular and gland-like structures.

 

  1. This figure shows a portion of the mesentery and omentum removed during a work-up of a 60-year-old woman with ascites and large multicystic ovarian masses. The lesions seen here are most consistent with the diagnosis of

 

 

  1. primary peritoneal benign tumor
  2. primary peritoneal malignant tumor
  3. metastatic carcinoma
  4. metastatic sarcoma
  5. lymphoma

 

ANS: C, The white nodules in the omentum most likely represent metastases of an ovarian carcinoma. The ovarian masses, described above, most likely represent ovarian carcinoma, which is often bilateral and typically metastasizes by seeding through the peritoneal cavity.

 

  1. This small intestinal lesion was removed from a 56-year-old woman and is most likely a

 

 

  1. tubular adenoma
  2. hamartoma
  3. carcinoma
  4. sarcoma
  5. pseudopolyp

 

ANS: C, This large partially exophytic and partially ulcerated necrotic lesion most likely represents an adenocarcinoma. Although adenocarcinomas are uncommon in the small intestine, they are nevertheless more common than sarcomas. The tumor is too large and too irregular and necrotic to be benign.

 

  1. This slide illustrates the lesions seen in the partial colectomy specimen obtained from a 78-year-old man who has chronic constipation, left lower quadrant pain, and fever. On cross section, this sigmoid colon shows changes most consistent with the diagnosis of

 

 

  1. Crohn disease
  2. toxic megacolon
  3. carcinoma of the colon
  4. carcinoid
  5. diverticulitis

 

ANS: E, The cross section through this sigmoid colon shows the outpouchings typical of diverticulosis. Because the diverticula are surrounded by collars of fibrous tissue, it can be assumed that there is pericolonic inflammation, which originates in the diverticula. The disease thus is best classified as diverticulitis.
