92
Q

A

Infection

97
Q

How can corticosteroids delay wound healing?

A

By inhibiting protein and collagen synthesis

98
Q

How can diabetes mellitus impair wound healing?

A

Primarily because of microangiopathy (small blood vessel disease) associated with it, but it also pours excess sugar into the wound (nutrients for infecting organisms)

99
Q

How can anemia delay wound healing?

A

It decreases oxygen delivered to the site of repair

100
Q

Why was grandma right about not picking your scabs?

A

It can disrupt the underlying partial epidermal layer and granulation tissue, setting back the healing process

101
Q

What’s dehiscence?

Q

What’s a hernia?

A

Protrusion of a body part somewhere it doesn’t belong

Q

Keloid

A

Hypertrophic scar

104
Q

Contracture

A

Abnormal excess wound contraction resulting in deformity and impaired movement

105
Q

Where is contracture most common and what disease is associated with it?

A

Palms (Dupuytren’s contracture)
Soles (Lederhosen disease)
Penis (Peyronie disease)

106
Q

What’s fibrosis?

A

Excessive interstitial collagen deposition usually due to chronic inflammation, recurring injury, persistent toxin, radiation, or autoimmune attack

107
Q

What causes the WORST fibrosis? And why?

A

Autoimmune diseases because the inciting agent is continually present and can’t be limited or eliminated

108
Q

What’s scleroderma?

A

It shows how bad fibrosis can be! Progressive fibrosis of the fingers until they’re fixed into a claw hand, sometimes with gangrene of the fingertips. The face undergoes fibrosis until its frozen into an “iron mask”. It kills peristalsis to move food into the stomach. It also leads to renal failure. Basically your life is the worst.

Who made the link of disease to malfunction at the cellular level?

A

Virchow
