decreased canal acidity

can you treat otitis media w/ acetic acid if the pt has a perforated ear drum?

fungal ## Footnote •Aspergillus Candida spp

what is the most common cause of perforated TM?

improper attempts at wax removal or ear cleaning.

Pt reports to clinic for yearly physical. Upon examination of the ear canal you notice a perforated TM. when you ask the pt if they are experiencing any symptoms in that ear they report otorrhea (drainage). How do we treat?

Systemic antibiotics if otorrhea from a TMP.

When treating a perforated TM you should AVOID eardrops containing: (3 things)

gentamicin neomycin sulfate, tobramycin.

Dx? what causes this?

Auricular Hematoma ## Footnote * Results from direct trauma * Shearing forces - separation of the anterior auricular perichondrium from the cartilage

Patients with oral lesions can be categorized into three clinical groups:

Pathogens responsible for Oral Candida

* Candida albicans * Candida glabrata * C. krusei * C. tropicalis

2 classifications of oral candida

* Pseudomembranous – most common * White plaques on buccal mucosa, palate, tongue and oropharynx * Atrophic (denture stomatitis) * Found under upper dentures * Erythema without plaques

Tx of Oral Candida?

A pt comes to clinic complaining of dry mouth and difficulty swallowing. Upon examination you notice 2 things: He wears partial dentures (upper) and erythema without plaques. Dx? (be specific)

Oral Candida - Atrophic (denture stomatitis)

what is the most common type of oral candida\> how does it present?

Pseudomembranous ## Footnote •White plaques on buccal mucosa, palate, tongue and oropharynx

HSV-1

how would primary HSV-1 present? | (think systemic)

* Fevers * Lymphadenopathy * Decrease oral intake * Poor ability to manage oral secretions due to pain
