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.
