The authors present a case of combined preseptal and postseptal cellulitis of odontogenic origin. The infection started as a dental abscess associated with a first maxillary molar. The infection spread into the paranasal sinus, developed into a pansinusitis, and then spread into the preseptal and postseptal tissues. In addition to extraction of the infected tooth, the patient underwent bilateral nasal endoscopy, maxillary antrostomy, total ethmoidectomy, sphenoidotomy, and frontal sinusotomy with balloon dilation. Sinus cultures were positive for 2+ microaerophilic streptococci.

In the following case presentation, a young man who incurred orbital compartment syndrome (OCS) from physical trauma significantly improved from timely lateral canthotomy. Lateral canthotomy is recommended to be performed as soon as possible to avoid permanent vision loss, which is the most feared complication associated with orbital compartment syndrome. This procedure completely restored vision in the patient and permitted prompt discharge.

Pediatric seizures are a common presentation to the emergency department. It is important to separate non-febrile seizures from febrile seizures, as non-febrile seizures have a much broader differential diagnosis. For infants less than six months of age with a normal exam, hyponatremia is the leading cause of new onset non-febrile seizure. Most commonly, this is secondary to water intoxication from inappropriate feeding practices. This case report will review the initial workup of new onset non-febrile seizures in an infant and treatment recommendations for seizures secondary to hyponatremia.
