1. Why is there a different approach to stab and gunshot wounds?
Show answer
Whereas one third of stab wounds to the anterior abdomen do not penetrate the peritoneum, 80% of gunshot wounds violate the peritoneum. Furthermore, penetration of the peritoneum by a bullet is associated with visceral or vascular injuries in > 95% of cases, whereas only one third of stab wounds violating the peritoneal cavity produce significant injury. (See Figure 24-1.)

23. How fat is fat?
Show answer
Lean body mass is three times more metabolically active than adipose tissue. Multiple definitions of clinical obesity exist: > 120% ideal body weight (IBW), > 130% IBW, body mass index (BMI) > 30, body fat > 24-28% of body weight in men and > 30-35% in women. Measured weight is a poor indicator of relative adiposity. Self-reported weights or weights reported by family members are often erroneous in the ICU setting. Fluid resuscitation and edema make visual assessment challenging and limit the usefulness of noninvasive technology such as bioelectrical impedance (BIA) for measuring body composition. Although measured energy expenditure in kcal/kg of actual weight may sometimes approach that of normal-weight patients, feeding at the measured body weight level may be associated with profound hyperglycemia, hypercapnea, and the inability to clear triglycerides.

Denis D. Bensard M.D., David A. Partrick M.D.
1. What are tracheoesophageal fistula (TEF) and esophageal atresia (EA)?
Show answer
The trachea and esophagus appear as a ventral diverticulum arising from the primitive foregut during the third week of gestation. The trachea and esophagus undergo separation by the ingrowth of ectodermal ridges during the fourth week of gestation. Failure of separation results in anomalous connection of the trachea to the esophagus (i.e., TEF) with or without incomplete formation of the esophagus (i.e., EA).

Hypertrophic Pyloric Stenosis
82 HYPERTROPHIC PYLORIC STENOSIS
Denis D. Bensard M.D.
1. What is pyloric stenosis?
Show answer
Hypertrophic pyloric stenosis (HPS) is idiopathic thickening and elongation of the pylorus that produces gastric outlet obstruction. HPS is the most common surgical cause of nonbilious vomiting in infants. Offspring of an affected parent have an increased incidence of HPS (10%); the highest rate (20%) occurs in boys born to affected mothers.

3. Which noninvasive tests should be used to diagnose extracranial carotid artery disease?

ARTERIAL INSUFFICIENCY
69 ARTERIAL INSUFFICIENCY
Mark Nehler M.D., William C. Krupski M.D.
1. Describe claudication and its physiology.
Show answer
Intermittent claudication consists of reproducible lower extremity muscular pain induced by exercise and relieved by short periods of rest. It is caused by arterial obstruction to affected muscular beds, which restricts the normal exercise-induced increase in blood flow, producing transient muscle ischemia. Studies have shown that more than half of patients with intermittent claudication have never complained of this symptom to their physicians, assuming that difficulty with walking is a normal consequence of aging.

2. What is a fatty streak?
Show answer
Fatty streaks or type II lesions are visible as yellow-colored streaks, patches, or spots on the intimal surface of arteries. Microscopically, they are characterized by the intracellular accumulation of lipid.
