26
What are a few other things to ask the patient with an animal bite wound?
- day and time of bite - is the animal a pet? - does the animal have a current rabies vaccine? - was the animal provoked? - was the animal exhibiting abnormal behavior prior to the bite?
27
What are a few other things to ask the patient with a human bite wound?

29
What percentage of dog bites will become infected?
2-20%
30
What percentage of cat bites will become infected?
5-50%
31
What percentage of human bites will become infected?
10-50%
32
Why do human bite wounds tend to be more serious?
- the human mouth has more varied microflora - closed fist bite wound etiology in which the tendons glide proximally, bringing the bacteria under the intact proximal skin
33
In the United States, only __% of suspected spider bites were actually caused by spiders
45
34
In the United States, only two types of spider bites require medical intervention, what are they?
- Black widow | - Brown recluse

36
Describe patient symptoms following a black widow spider bite
They become acutely ill within 1-3 hours of the bite. Experiencing weakness, headache, nausea/vomiting, hyperreflexia, dyspnea, diaphoresis, HTN, and tachycardia.
37
Describe the presentation of a black widow spider bite
Small bite surrounded by erythema with urticarial rash, stinging sensation
38
How is a black widow spider bite treated?

3-5
41
Describe the general presentation of a brown recluse spider bite within the first 24 hours
Red inflammation, blue thrombosis, and white ischemia present with a possibly necrotic center
42
Describe patient symptoms following a brown recluse spider bite

43
The mean wound healing time for a brown recluse spider bite ranges from _ to __ weeks
5-17
44
Why should superficial heat be avoided following a brown recluse spider bite?
it may increase necrosis
45
Why is early surgical excision contraindicated following a spider bite?
It may spread the spider's venom and prolong the inflammatory response
46
When is surgical intervention appropriate following a spider bite?
If the wound is stable but not healing after 6-8 weeks of appropriate wound care

fibrosis
50
What causes radiation fibrosis?
The overproduction and decreased degradation of collagen as well as hypovascularity
51
What does radiation fibrosis look like?

53
Describe grade 1 skin reaction due to radiation therapy

50 25 25
61
What are 5 differential diagnoses for Pyoderma Gangrenosum?
- cancer - vasculitis - adverse drug reaction - spider bite - chronic venous insufficiency
62
Describe the progression of Pyoderma Gangrenosum
- Begins as small, painful papule, vesicle, or pustule on lower extremities and trunk - Progresses to full-thickness ulceration with irregular borders and undermining present
63
Describe the general presentation of Pyoderma Gangrenosum
- Indurated, boggy - Purulent and hemorrhagic exudates - Erythematous due to inflammation - Wound bed covered with eschar or slough
64
What are a few patient complaints associated with Pyoderma Gangrenosum?
- fever - malaise - myalgia
65
Under what 2 circumstances should Pyoderma Gangrenosum be suspected?
- If wound cultures are positive and do not respond to antibiotics - If the wound does not respond to standard care for presumed wound etiology
66
The mainstay of pyoderma gangrenosum treatment includes medication and local wound care. What type of medication is suggested?
- Immunosuppressive agents, such as cyclosporin | - Corticosteroids that can be administered either systemically or topically injected
67
Is debridement suggested in patients with pyoderma gangrenosum?
Gentle and limited debridement of slough and necrotic tissue, however sharp or surgical debridement is contraindicated because it increases the inflammatory response leading to severe exacerbations
68
Pyoderma gangrenosum healing is extremely ____ and recurrence is _____.
slow recurrence
