| ==Viral Parotitis (Mumps)== | | ==Types== |
| ===Background===
| | [[File:Illu quiz hn 02.jpg|thumb|Salivary glands: #1 Parotid gland, #2 Submandibular gland, #3 Sublingual gland.]] |
| *Acute infection of the parotid glands
| | {{Salivary gland DDX}} |
| *Most often caused by the mumps virus; less commonly by influenza, parainfluenza, coxsackie, echo, HIV
| |
| *Most common in children <15yrs
| |
| *Contagious for 9d after onset of parotid swelling
| |
|
| |
|
| ===Clinical Features=== | | ==Differential Diagnosis== |
| *Prodrome of fever, malaise, HA, myalgias, arthralgias
| | {{Facial swelling DDX}} |
| *Unilateral or bilateral parotid swelling
| |
| *Unilateral orchitis (20-30% of male pts)
| |
|
| |
|

| ===Complications=== | | ==References== |
| *Mastitis, pancreatitis, aseptic meningitis, hearing loss, myocarditis, polyarthritis, hemolytic anemia

| ===Disposition===
| | [[Category:ENT]] |
| *Isolated parotitis or orchitis: manage as outpatient
| | [[Category:ID]] |
| *Sysemtic complications: admit
| |
| | |
| ==Suppurative Parotitis==
| |
| ===Background===
| |
| *Serious bacterial infection of parotid gland that occurs in pts w/ decreased salivary flow
| |
| **Caused by retrograde migration of oral bacteria into salivary ducts and parenchyma
| |
| **Usually caused by staph, strep, anerobes
| |
| *Risk factors:
| |
| **Dehydration
| |
| **Prematurity or advanced age
| |
| **Sialolithiasis
| |
| **Oral neoplasms
| |
| **Salivary duct strictures
| |
| **Meds (cause systemic dehydration or decrease salivary flow)
| |
| ***Diuretics
| |
| ***Antihistamines
| |
| ***TCAs
| |
| ***B-blockers
| |
| **Chronic illnesses
| |
| ***HIV
| |
| ***Sjogren syndrome
| |
| ***Anorexia/bulimia
| |
| | |
| ===Clinical Features===
| |
| *Rapid onset
| |
| *Skin over parotid gland is red and tender
| |
| *Purulent drainage from Stensen's duct
| |
| *Fever
| |
| *Trismus
| |
| | |
| ===Treatment===
| |
| #Hydrate the volume-depleted patient
| |
| #Massage and apply heat to the affected gland
| |
| #Stimulate salivation using sialagogues such as lemon drops
| |
| #Abx
| |
| ##PO abx if pts can tolerate oral liquids and have no evidence of systemic illness
| |
| ##Amoxicillin-clavulanate OR clindamycin OR cephalexin + metronidazole
| |
| ##IV abx
| |
| ###Indicated for trismus, inability to tolerate oral liquids, or immunocompromised
| |
| ###Nafcillin OR ampicillin-sulbactam OR (vancomycin + metronidazole (if MRSA suspected))
| |
| | |
| ==Sialolithiasis==
