Influenza A-Associated Epiglottitis and Compensatory Pursed Lip Breathing in an Infant.

The last 3 decades have seen a shift in the epidemiology of epiglottitis. Epiglottitis was once most commonly associated with Haemophilus influenzae type B. However, with the implementation of the H. influenzae type B vaccine in 1985, the incidence has drastically declined. There are now new emerging pathogens-bacteria, viruses, and fungi-causing epiglottitis. Here, we report the first case of epiglottitis secondary to influenza A in a former full-term, vaccinated infant who presented with cough, fever, stridor, pursed lip breathing, and progressive respiratory distress and eventual respiratory failure. This case highlights the presentation and clinical course of epiglottitis and describes a rare clinical feature, pursed lip breathing, in an infant.

Congenital left paraduodenal hernia causing chronic abdominal pain and abdominal catastrophe.

Paraduodenal hernias are the most common type of congenital internal hernia. Because of its overall rare incidence, this entity is often overlooked during initial assessment of the patient. Lack of specific diagnostic criteria also makes diagnosis exceedingly difficult, and the resulting diagnostic delays can lead to tragic outcomes for patients. Despite these perceived barriers to timely diagnosis, there may be specific radiographic findings that, when combined with the appropriate constellation of clinical symptoms, would aid in diagnosis. This patient first presented at 8 years of age with vague symptoms of postprandial emesis, chronic abdominal pain, nausea, and syncope. Over the span of 6 years he was evaluated 2 to 3 times a year with similar complaints, all of which quickly resolved spontaneously. He underwent multiple laboratory, imaging, and endoscopic studies, which were nondiagnostic. It was not until he developed signs of a high-grade obstruction and extremis that he was found to have a large left paraduodenal hernia that had volvulized around the superior mesenteric axis. This resulted in the loss of the entire superior mesenteric axis distribution of the small and large intestine and necrosis of the duodenum. In cases of chronic intermittent obstruction without clear etiology, careful attention and consideration should be given to the constellation of symptoms, imaging studies, and potential use of diagnostic laparoscopy. Increased vigilance by primary care and consulting physicians is necessary to detect this rare but readily correctable condition.
