48
Q

An 8-year-old boy is brought to clinic by his parents because they are concerned that he has not been doing his homework. His teacher recently called the parents to say that their son seems distracted in class, constantly interrupts other children when they are speaking, and is very fidgety. When you speak with the boy, he tells you that he did not know about the homework assignments and that he tries hard to pay attention in class. What is the next best step in management?

A Prescribe a stimulant medication for ADHD
B Suggest behavior modification for the child and parenting classes
C Group therapy for the child
D Do nothing, as this child’s behavior is normal
E Contact the teacher to find out more about his behavior. Find out more about the child’s behavior at home

A

E. Contacting the teacher to find out more about the child’s behavior at school and learning more about his behavior at home are the best ways to determine if 6 of the symptoms are present in 2 or more settings, which is required to make the diagnosis of ADHD. It also will be important to learn more about other aspects of this child’s life, as there are several factors that can lead to acting out (including learning disability, hearing disability, family stress, and abuse).

before starting meds or therapy.

49
Q

An 8-year-old healthy obese African American male with no past medical history is found to have a blood pressure of 125/90 mmHg on all four extremities on routine evaluation during an office visit for well-child care. Review of symptoms is negative. A physical exam and screening bloodwork are performed. Both are normal, with the exception of his blood pressure and obesity. What is the most likely diagnosis?

A		Primary hypertension	
B		Renal artery stenosis	
C		Coarctation of the aorta	
D		Pheochromocytoma	
E		Hyperthyroidism
A

A Given the mild hypertension and the patient’s age, symptoms are unlikely to be present. Other etiologies should be ruled out, but review of symptoms, physical examination, and laboratory studies do not suggest other etiologies.

50
Q

Billy, a 7-year-old boy, presents to the clinic with complaints of headaches and episodes of feeling sweaty and flushed. He also reports that at times he feels as if his heart is racing. Billy was full term, had an uncomplicated birth, and has been otherwise healthy until now. On exam his BP is 120/80 mmHg and is the same in his upper and lower extremities. His weight and height are in the 50th percentile for his age. What is a likely cause of Billy’s hypertension?

A		Coarctation of the aorta	
B		Renal vascular disease	
C		Renal insufficiency due to renal scarring	
D		Catecholamine excess	
E		Primary hypertension
A

D
(pheochromocytoma or neuroblastoma) should be suspected in a child who is hypertensive and has episodes of sudden sweating, flushing, or feels that his heart is racing. Billy is exhibiting these signs and a urine catecholamine testing would be appropriate in this case.

51
Q

Jane is an 8-year-old girl who presents to your clinic for follow-up after being hospitalized for status asthmaticus. She has just completed a 10-day course of systemic steroids. Given her history of moderate persistent asthma, her outpatient regimen includes Advair, a combined steroid and bronchodilator. She was also diagnosed with ADHD one year ago and was started on Concerta, 18 gm PO once a day. Her BMI today is at the 83rd percentile for her age, and her blood pressure is at the 98th percentile for her age. What is the most likely cause of her stage I hypertension?

A		Obesity	
B		The blood pressure cuff is too big	
C		Medications	
D		Renal insufficiency	
E		Neurofibromatosis 1
A

C
steroids and amphetamines can cause increases in blood pressure, especially when used in combination. Steroids increase blood pressure by mimicking endogenous cortisol and the sympathetic fight or flight response. Amphetamines mimic norepinephrine, stimulating alpha and beta adrenergic receptors, causing an overall increase in blood pressure.

Chronic drug = amphetamines

+ acute drug = steroids

==> can increase BP acute (similar to how it can pseudo-increase # of neutrophils)

52
Q

George is a 7-year-old boy frequently in trouble at school for being disruptive and inappropriately talkative in class, not following directions set by his teacher, and not working well with classmates during group activities. His mother relates that at home George is always on the go, sleeping only 6 to 7 hours a night. He does not follow her rules all the time either, including not doing his homework, and sometimes putting himself in danger by doing things she tells him not to do, such as running away unaccompanied. Which of the following is the most likely diagnosis?

A		Bipolar mood disorder	
B		Anti-social personality disorder	
C		Conversion disorder	
D		ADHD	
E		Rett syndrome
A

D. DHD is characterized by the triad of impulsivity, hyperactivity, and inattention. Other symptoms include motor impairment and emotional labiality. ADHD is typically diagnosed before the age of 7 but persists into adulthood. Intelligence is usually normal, but individuals with ADHD commonly perform more poorly academically than would be expected for their IQ.
