Write a queAcute Viral Rhinosinusitis Acute viral rhinosinusitis is an inflammation of the nasal cavity and sinuses typically following a viral upper respiratory infection. The mucosal lining becomes inflamed, leading to blocked sinus drainage and subsequent symptoms, such as fever, sinus tenderness, and nasal discharge, which can be exacerbated by bending over. While the majority of cases are caused by viruses like rhinovirus, influenza, and parainfluenza, bacterial superinfection can occur, commonly with Streptococcus pneumoniae, Haemophilus influenzae, or Moraxella catarrhalis.stion and answer flashcard for

Pseudotumor cerebri This condition is characterized by idiopathic increased intracranial pressure. Conditions that have been linked to pseudotumor cerebri include Addison disease, lupus, and blood-clotting disorders. The medication isotretinoin (Accutane) has also been implicated in the development of pseudotumor cerebri.

Pseudotumor Cerebri

• Associated Conditions:

  • Addison disease
