○ bilateral joint inflammation
○ inflammation of bone with ligament swelling
○ inflamed bone and cartilage causing swelling
○ inflammation of a bone joint causing bone hypertrophy

1. a chlamydial infection causing ________ is known as trach/oma.

○ swollen eyelids
○ corneal scars
○ blindness
○ rough swollen eye lesions

Explanation:

Question 55

Osteoarthritis is a joint disorder where the bone and cartilage in the joint become inflamed, leading to swelling. Let's analyze each option:

• "bilateral joint inflammation": Osteoarthritis isn't necessarily bilateral (affecting both sides) by definition, and this is too vague.
• "inflammation of bone with ligament swelling": Osteoarthritis involves joint (bone + cartilage) not just bone and ligament.
• "inflamed bone and cartilage causing swelling": This matches the definition of osteoarthritis, as it affects the joint's bone and cartilage, leading to inflammation and swelling.
• "inflammation of a bone joint causing bone hypertrophy": Bone hypertrophy (excessive bone growth) isn't the primary feature of osteoarthritis; it's more about cartilage breakdown and bone/cartilage inflammation.

Trachoma (trach/oma) is caused by chlamydial infection and is characterized by rough, swollen eye lesions (follicles or papillae) on the conjunctiva. Let's check options:

• "swollen eyelids": While eyelids can be involved, the key lesion is the rough, swollen eye (conjunctival) lesions.
• "corneal scars": Corneal scarring is a late complication, not the defining feature of trachoma's presentation.
• "blindness": Blindness is a severe late outcome, not the direct result that defines trachoma.
• "rough swollen eye lesions": This accurately describes the conjunctival lesions seen in trachoma due to chlamydial infection.

Answer:

inflamed bone and cartilage causing swelling
