Case Studies

v  A 3-year-old girl with moderate mental retardation is brought to the clinic by her mother because she has been complaining that her arm hurts. On physical examination, the girl has several bruises on her thorax and a tender right forearm. On laboratory examination, you discover a normocytic, normochromic anemia and basophilic stippling. On x-ray, you find signs of multiple fractures of different ages and increased density at the metaphyseal plate of the growing long bones.

1. Which of the following is the most appropriatetreatment?

(A) edetate calcium disodium (CaEDTA)
(B) flumazenil (Romazicon)
(C) naloxone (Narcan)
(D) deferoxamine (Desferal)
(E) acetylcysteine (Mucomyst)

2. Which of the following is the most likely cause of this girl’s bruises?

(A) Thrombocytopenia
(B) Developmental coordination disorder
(C) Malnutrition
(D) Physical abuse
(E) Hepatic failure

1. (A) CaEDTA is a chelating agent used to treat lead toxicity. Flumazenil is used to reverse the sedating effects of excess benzodiazepines, and naloxone is used to reverse the effects of excess opiates. Deferoxamine is a chelating agent used to treat iron toxicity. Acetylcysteine is used to treat acetaminophen toxicity.

2. (D) The girl’s bruises are most likely the result of physical abuse, which is strongly suggested by the presence of multiple fractures of different ages. Thrombocytopenia and malnutrition are rare in the United States. In developmental coordination disorder, there is a delay in achieving major milestones and clumsiness, but there is not typically a pattern of repeated injury. Hepatic failure is extremely rare in a 3-year-old child.

v  A 6-year-old boy is brought to the emergency department by his mother, who reports that he was playing on some steps in front of the house when he slipped and fell. She tells you that she is concerned that he might have broken his arm. An x-ray of the boy’s arm shows a fracture of the ulna, as well as signs of several old fractures of varying ages. Which of the following is the most appropriate action?

(A) Refer the boy to an orthopedist for further evaluation.
(B) Tell the mother that you notice that the boy has had multiple broken bones and recommend that she limit the boy’s sports activities.
(C) Set the current broken bone in a cast and recommend that the boy see his pediatrician for follow-up care.
(D) Recommend calcium supplements and a multiple vitamin daily.
(E) Tell the boy that you notice that he has had multiple broken bones and ask him how each of these fractures happened.

(E) The finding of multiple fractures especially when they are of different ages is a red flag for physical abuse. Even though the boy may be scared to report what happened for fear of punishment, it is important to try to talk with him alone and find out as much as possible. It is not appropriate to refer the boy to an orthopedist or his pediatrician prior to investigating the possibility of physical abuse. Recommending limited sports or extra vitamins does not address the question of whether the boy is safe at home.

v  A38-year-old male refugee presents to the mental health clinic at the urging of his family members. While lived in his former hometown, he had witnessed a friend killed during an explosion. Since that time, he has had chronic insomnia with ongoing nightmares of the event as well as occasional flashbacks. He describes always being “on edge,” avoiding crowds, and becoming easily startled with loud noises. He admits to regular khat use, especially when his symptoms are worse. Which of the following is the most appropriate treatment to begin for this patient?

(A) atypical antipsychotic
(B) benzodiazepine
(C) lithium
(D) serotonin-specific reuptake inhibitor
(E) valproic acid

(D) This patient is suffering from symptoms of posttraumatic stress disorder (PTSD), an anxiety disorder consisting of reexperiencing symptoms (e.g., nightmares, flashbacks, intrusive thoughts), increased arousal (e.g., hyperstartle, hypervigilence, irritability), and avoidance/ numbing. The best studied and most efficacious medications are considered to be the SSRIs. Antipsychotics, including the atypicals, should not be used as monotherapy, although may be used in conjunction, especially if there are associated psychotic symptoms. Benzodiazepines should be avoided in this patient population not only because of the significant comorbidity with substance addiction but also as they have not been found to be particularly effective.

Mood stabilizers, such as lithium and valproic acid, occasionally are used in addition to SSRIs in order to target the mood lability or aggression sometimes seen in PTSD.
