This verified resource provides comprehensive coverage of key MN566 Final Exam topics, including: Otolaryngology (ENT): Rinne Test: Compares air conduction (AC) to bone conduction (BC); tuning fork placed on mastoid process, then near external auditory meatus; normal AC BC; if BC AC, suggests conductive hearing loss Sensorineural Hearing Loss: Lesion in the organ of Corti or central neural pathways including CN VIII and auditory cortex; presbycusis is age-related sensorineural loss caused by degeneration of cochlear hair cells; causes include Meniere's disease, acoustic neuroma, aminoglycosides, aspirin, quinine, trauma, syphilis, mumps Conductive Hearing Loss: Impaired passage of sound waves through tympanic membrane and middle ear ossicles (malleus, incus, stapes); often reversible; causes include cerumen impaction, TM perforation, chronic ear infections, otosclerosis, congenital abnormalities Acoustic Neuroma: Unilateral sensorineural hearing loss with headache; benign tumor of vestibulocochlear nerve (CN VIII) Presbycusis: Age-related sensorineural hearing loss; bilateral and progressive; affects high frequencies Tinnitus: Vibratory (transmission of vibrations to cochlea from adjacent tissues) vs Nonvibratory (biochemical changes in neural hearing mechanisms) Meniere's Disease: Peripheral sensory disorder of labyrinth and cochlea; increased endolymphatic pressure causing recurrent attacks of tinnitus, vertigo, and progressive hearing loss; acute episodes last 20 minutes to 3 hours; cessation of vertigo with complete hearing loss in advanced cases Otitis Externa (Swimmer's Ear): Inflammation of membranous lining of auditory canal; classic sign = tenderness on traction of pinna AND/OR pain on pressure over tragus; most commonly caused by microbial infection; black, malodorous discharge indicates fungal infection (otomycosis) most commonly due to Aspergillus niger or Candida; patients should avoid water in ears for 4-6 weeks after symptoms subside Otitis Media: Inflammation of middle ear structures; AOM (suppurative/purulent) presents with otalgia, otorrhea, fever; OME involves transudation of plasma fluid with stuffiness, fullness, loss of auditory acuity (pain rare); if effusion persists 12 weeks unresponsive to treatment, consider 10-day antibiotic course and ENT referral Vasomotor Rhinitis: Non-allergic, non-infectious rhinitis triggered by hormonal changes (estrogen fluctuations during pregnancy/menopause) Viral Rhinitis: Accompanied by malaise, headache, sore throat, occasionally fever Allergic Rhinitis: Patients complain of itching in nasal passages, conjunctivae, roof of mouth, epiphora (excess tearing with stringy discharge); intranasal corticosteroids are best first-line treatment Rhinosinusitis: Inflammation of sinuses rarely occurs without concurrent nasal inflammation Kiesselbach's Plexus: Most common site of anterior epistaxis (nosebleed); anastomosis of septal branch of anterior ethmoid artery, septal branch of superior labial artery, and lateral nasal branch of sphenopalatine artery; trauma (nose picking) is most common direct cause; first-line treatment = apply pressure over nasal alar cartilage for 10-15 minutes with patient leaning forward Ophthalmology: Retinal Tear/Detachment: Any patient complaining of seeing flashing lights should be evaluated immediately Blepharitis: Inflammation of eyelids and margins; presents with itching, burning, foreign body sensation, photophobia, tearing; infectious blepharitis treated with topical antibiotic ointment (bacitracin or erythromycin 0.5%) applied at bedtime after gentle cleansing and warm compresses for 7-10 days Hordeolum (Stye): Acute, erythematous, tender lump within eyelid; external = hair follicle infection; internal = Meibomian gland infection Chalazion: Granulomatous infection of Meibomian gland; painless swelling; initially may be tender before evolving into nontender lump Conjunctival Inflammation: Hallmark is hyperemia of ocular and palpebral surfaces with engorged, superficial capillaries Infectious Diseases: Diabetic Retinopathy: Lisinopril (ACE inhibitor) is the only pharmacologic agent found to slow progression Acute Macular Degeneration: Four drugs
