Chemosis: traumatic carotid cavernous fistula

Abstract

metabolic alkalosis in HPS, with marked reduction in the time to pyloromyotomy. 3 We believe that it is important for surgeons and anaesthetists to be aware of the possible effect that H2-antagonists may have in reducing the electrolyte disturbance in infants with HPS; such awareness may result in a more expeditious pyloromyotomy.

Acute Bilateral Periorbital Edema in a Psychiatric Patient

“…1 Presence of chemosis is especially concerning for infection, thyroid eye disease, or angioedema and may indicate vascular abnormalities. [2][3][4] While ceftriaxone and vancomycin were started for possible cellulitis, they were discontinued after 2 days as the patient's afebrile status examination and CT findings (Figure 2) made this less likely. Additionally, bilateral preseptal or orbital cellulitis would be extremely uncommon.…”
