Counseling and challenge

Suggested response to challenge: “Ms. Campbell, I can understand that you are bothered by your cough. At this point, unfortunately, I can't say exactly what is causing it. I would like to run some tests first to find the right diagnosis, and then start you on an appropriate treatment once we know exactly what is going on. There are many treatable causes of cough, and we have an array of medications that can help, depending on the cause. My team and I will make sure that we do our best to help you. Do you have any other questions or concerns?”

Differential diagnoses

  1. Asthma: Intermittent coughing spells and dyspnea brought on by specific triggers (e.g., exercise, allergen exposure) are the hallmark of asthma, the most likely diagnosis in this case. The patient is young, otherwise healthy, and has a personal and family history of atopic dermatitis and allergy, which are often associated with asthma.
  2. Acute bronchitis: Symptoms of productive, painful cough and low-grade fever following an upper respiratory infection support the diagnosis of acute bronchitis in this patient. Acute bronchitis is viral in > 90% of cases and as such does not usually require antibiotic treatment. However, this patient's symptoms pre-date her URI and are aggravated by exercise, making asthma a more likely diagnosis. The worsening of symptoms over the past few days is probably due to bronchial hyperresponsiveness to increased mucus production.
  3. Atypical pneumonia: Dry cough, dyspnea, and low-grade fever are clinical features of atypical pneumonia, in which the pulmonary examination is often unremarkable, which is the case here. School children and young adults are typically affected, and the disease can take a subacute course, lasting several weeks. However, the intermittent nature of this patient's cough, the fact that the cough has specific triggers, her personal and family history of atopic dermatitis and allergies, and her current symptoms of a URI make this diagnosis the least likely of the three.
