A 3-year old boy was admitted to the ER because of difficulty of breathing. History revealed that he developed high grade fever and sore throat 24 hours prior to consult with associated difficulty of swallowing. Physical examination showed a very toxic looking boy, highly febrile, with labored breathing and hyper extended neck and drooling of the saliva. The most plausible diagnosis of the above case is:

A. Acute infectious laryngitis

B. Acute epiglottitis

C. Acute laryngotracheobronchitis

D. Acute bacterial tracheitis

B - Acute epiglotittis This is a potentially lethal condition characteristically presenting with acute fulminating course of high grade fever, sore throat, dyspnea and rapidly progressing respiratory obstruction. Drooling of the saliva is frequently present and is due to difficulty of swallowing. Hyperextension of the neck is due to his attempt to maintain the patency of the airway. This fatal disease is frequently caused by H. influenzae.

Recurrent gum bleeding was noted in a 7-year old female. CBC and platelet count are normal, Prothrombin time is normal but bleeding time and partial thromboplastin time are prolonged. The most likely diagnosis is:

A. ITP

B. Hypoprothrombinemia

C. TTP

D. Von Willebrand Disease

D - Von Willebrand disease is a disorder associated with mucocutaneous hemorrhages. The disorder is due to deficiency of Von Willebrand factor, a glycoprotein that is synthesized in megakaryocytes and endothelial cells. During normal hemostasis VWF adheres to the endothelial matrix after vascular damage. Changes in the conformation of VWF cause platelets to be an adhere to VWF resulting to platelet activation and recruitment of additional platelets. VWF also serves as the carrier protein for plasma factor VIII. Severe deficiency of VWF can cause prolongation of bleeding time and PTT. ITP (Choice A) results only to prolonged BT because the coagulation phase is not affected. Hypoprothrombinemia (Choice B) results to decreased synthesis of Vitamin K – dependent factor causing prolonged PT. ITP (Choice C) is a form of microangiopathic hemolytic anemia with thrombocytopenia.

The pathologic findings of bronchopulmonary dysplasia (BPD) consist of the following:

A. Decreased alveolarization

B. Decreased alveolar septation

C. Minimal airway disease

D. All of the above

BPD is a result of lung injury in infants requiring mechanical ventilation and supplemental oxygenation. It is apparent that patients with BPD have decreased alveolarization, alveolar septation and minimal airway disease all of which suggest arrest in lung development. The lung injury occurring in children is due to an interaction of multiple factors. Since RDS is a disease of progressive alveolar collapse, Atelectasis which is affected by insufficient PEEP together with ventilator-induced increased lung volume and regional overdistention promotes injury. Oxygen promotes injury by producing free radical that cannot be metabolized by immature antioxidant systems. Therefore, mechanical ventilation and /or oxygen injure the preterm lung by affecting alveolar and vascular development. Moreover, inflammation as measured by circulating neutrophils and macrophage in the alveolar fluid and pro-inflammatory cytokines contribute to the progression of the lung injury. (Nelson’s Textbook of Pediatrics, 17th ed, 2004)
