Category: generalpediatrics-Pulmonology

Findings: respiratory distress in newborn, pulmonary hypertension, decreased breath sounds on the left side, flat or scaphoid abdomen

Question: What fits these findings?


Croup

Category: generalpediatrics-Pulmonology

Findings: barky cough, inspiratory stridor, low grade fever, retractions, subglottic narrowing on neck x-ray

Category: generalpediatrics-Pulmonology

Findings: focal infiltrates on CXR, hilar adenopathy, mild fever and cough, exposure to farm animals

Notes: Seen with bat and chicken droppings, and found commonly in the Ohio and Mississippi river valleys.


Idiopathic Pulmonary Hemosiderosis

Category: generalpediatrics-Pulmonology

Findings: cough with hemoptysis, iron deficiency anemia, fatigue, worsening dyspnea, sputum with hemosiderin-laden alveolar macrophages


Laryngomalacia

Category: generalpediatrics-Pulmonology

Findings: inspiratory stridor in 3 month old infant worse when supine or agitated, no fever or signs of infection

Notes: Due to prolapse of epiglottis or tissue or cartilage near epiglottis. Obtain ENT consult for flexible laryngoscopy. Unlike croup, this is not caused by an infection, usually viral.

Question: Which disease is associated with these findings?


Laryngomalacia

Category: generalpediatrics-Pulmonology

Findings: inspiratory stridor in infant, worse when child is supine or upset, retractions, floppy larynx cartilage

Notes: Most cases will self-resolve by one to two years of age. Severe cases may require supraglottoplasty to keep airway open above vocal cords.

Question: What fits these findings?


Mycoplasma Pneumoniae

Category: generalpediatrics-Pulmonology

Findings: cough and wheezing in adolescent, fever, joint pain, splenomegaly, erythema multiforme, pharyngitis, confusion, multifocal diffuse infiltrates or lobar consolidation

Question: What organism causes these findings?


Pulmonary hemosiderosis

Category: generalpediatrics-Pulmonology

Findings: anemia, cough, crackles on exam, potential milk protein intolerance, hemosiderin laden alveolar macrophages

Notes: Alveolar hemorrhage leaded to recurrent respiratory symptoms. May be caused by granulomatosis with polyangitis, Goodpasture, SLE, and milk protein intolerance among other conditions. May treat with steroids and immunosuppressants.


Pulmonary Sequestration

Category: generalpediatrics-Pulmonology

Findings: recurrent pneumonia on same side, chronic cough

Notes: Lung tissue disconnected from trachea and has its own blood supply

Category: generalpediatrics-Pulmonology

Findings: croup and mild stridor at night, asymptomatic during day, treated with gastric reflux and allergy medications

Question: Which organism causes these findings?


Tracheomalacia

Category: generalpediatrics-Pulmonology

Findings: expiratory stridor worsened with agitation, usually resolves by 6 to 12 months

Notes: Due to collapsing tracheal wall. Unlike laryngomalacia, is expiratory instead of inspiratory.

Question: What fits these findings?


Tracheomalacia

Category: generalpediatrics-Pulmonology

Findings: expiratory stridor in infant, frequent respiratory infections

Notes: Due to obstruction in lower trachea


Vascular Ring

Category: generalpediatrics-Pulmonology

Findings: trouble feeding in infant, gastroesophageal reflux, expiratory stridor since birth, evaluated with barium swallow, sometimes caused by double aortic arch

Notes: Perform CT angiography or MRA for further workup
