Study Notes

Oral Pathologies

Aphthous Ulcers
- Clustered, recurrent oral lesions associated with immunologic disorders like celiac disease and IBS.
- Appear as shallow ulcerations with a red halo, painful, affecting up to 40% of the population, often resolving in 7-10 days.
Mucocele
- Common salivary gland lesion caused by saliva leakage due to trauma, often located on the lower lip.
- Fluid-filled, blue translucent swelling that changes size, particularly around meals.

Oral Infections

Candida albicans
- Causes "Thrush," presenting as a gray-white membrane easily scraped off, revealing an inflammatory base.
- Promoted by antibiotic usage that reduces beneficial oral bacteria.
Strep Pharyngitis
- Caused primarily by Streptococcus pyogenes, associated with symptoms of fiery red tongue and can lead to rheumatic fever.

Oral Manifestations of Systemic Diseases

Initial infection symptoms in children manifest with oral vesicles, fever, and lymphadenopathy.
Adults may experience recurrent acute herpes pharyngitis.

Periodontal Diseases

Gingivitis
- Inflammatory response due to plaque buildup, leading to redness, bleeding, and contour changes.
Periodontitis
- Affects supporting structures of teeth and can lead to serious conditions like endocarditis and abscesses.
Irritation Fibroma
- Traumatic fibroma due to repetitive trauma, presenting as a hard mass, primarily in the buccal mucosa.
Pyogenic Granuloma
- Highly vascular growth, often seen in children and pregnant women.

Oral Lesions

Factors like hypertrophy and neoplasia contribute to oral lesions' development, often presenting as red, ulcerated nodular lesions.
Peripheral Ossifying Fibroma
- Reactive lesion observed mainly in young females, recurring in 15-20% of cases.

Behcet's Disease

A rare autoimmune disorder presenting with recurrent mouth sores, eye inflammation, and vascular complications.

Hairy Leukoplakia

An EBV-associated oral lesion primarily in immunocompromised individuals, presenting as white, "hairy" patches on the tongue.

Ear Conditions

Cholesteatoma
- Non-neoplastic cystic lesions resulting from chronic otitis media.
Otosclerosis
- Progressive condition causing hearing loss, linked to age and familial history.
Otitis Media
- Caused by pathogens like Pseudomonas aeruginosa in diabetic patients, presenting with acute or chronic symptoms.

Blepharitis

Inflammation of eyelid margins, with anterior blepharitis linked to staphylococcal infections and seborrheic conditions.

Ophthalmology

Glaucoma Types
- Open-Angle: Chronic optic neuropathy with peripheral vision loss; common causes include age and family history.
- Closed-Angle: Rare, acute increase in eye pressure distinguished by blocked aqueous outflow, risk factors include older age and certain medical conditions.
Cataracts
- Clouding of the lens leading to blurred vision; risk factors include aging, genetics, and certain medications.

Retinal Detachment and Macular Degeneration

Causes of Detachment
- More prevalent in older populations, associated with eye injuries and diabetic retinopathy.
Signs and Symptoms
- Flashes of light, floaters, and blurred vision are indicative of retinal detachment.

Retinoblastoma

Malignant eye tumor in young children, often presenting with leukocoria and related symptoms like eye pain and vision problems.

Proliferative Diabetic Retinopathy

Advanced form characterized by abnormal blood vessels leading to potential vision loss; early stages typically asymptomatic.

Anterior Blepharitis and Chalazion

Anterior blepharitis can be associated with skin bacteria; treatment often requires topical antibiotics.
Chalazion is a non-tender, slow-growing lump caused by blocked oil glands in the eyelid.

Pterygium and Pinguecula

Pinguecula is a benign growth that can lead to pterygium, which grows onto the cornea and can obstruct vision, common in sun-exposed individuals.

Retinal Arteriosclerosis

Blocked retinal arteries can lead to vision problems and are influenced by atherosclerosis and systemic conditions.

Respiratory and Immune Responses

Allergic Rhinitis
- IgE-mediated hypersensitivity to various allergens leading to symptoms like mucosal edema and eosinophilic infiltration.
Type 1 Hypersensitivity
- Immediate reaction caused by antigen binding to IgE on mast cells, resulting in symptoms such as vasodilation and vascular leakage.
Mast Cell Activation
- Critical for immediate hypersensitivity responses, triggered by cross-linking of IgE antibodies with antigens.
