well defined circumscribed pink to red patch or thin plaque with scaly/rough surface

99

Blanch with pressure

110
Q

Urticaria

Tx

A

First-line: 1st generation antihistamines (Benadryl, hydroxyzine)

A

Urticaria

112
Q
A

angioedema

Initial lesions are characterized by erythematous, irregularly-shaped, dusky red to pruritic macules, which progressively coalesce and evolve to flaccid blisters, which spread with pressure and break easily

Negative nikolsky sign

131
Q

erythema multiforme

minor vs major

A

Minor: target lesions distributed on extremities with no mucosal membrane involvement

Major:target lesions on extremities with central progression with mucosal membrane involvement. No epidermal detachment

132
Q

Erythema multiforme

Tx
Severe

A

Remove offending drugs, topical steroids, antihistamines, analgesics.

Systemic corticosteroids if severe.

Antibiotics if mycoplasma is inciting cause

133
Q

Brown recluse spider bite

general

A

Most common in the midwestern and southwestern US
The brown recluse spider has a violin pattern on it cephalothorax
Venom is cytotoxic and hemolytic – local symptoms, can be necrotic, associated with a lack of severe systemic symptoms.

134
Q

Brown rescluse bite

Clin Man

A

Burning sensation
Typical progression: erythema at bite site for 3 to 4 hours, followed by blanching of the affected area, followed by a “red halo” (erythematous margin around the ischemic center) for 24 to 72 hours, followed by a hemorrhagic bulla that undergoes eschar formation
May develop skin necrosis
Systemic side effects: fever, chills, nausea, vomiting, or a morbilliform rash

135
Q
A

Brown recluse spider bite

136
Q

Brown recluse spider bite

Tx

A

Local wound care and pain control
Most wounds heal spontaneously with adequate cleansing
Pain control: NSAIDs are mostly commonly used, opioids if severe, refractory pain
Necrosis: debridement once the lesion is well demarcated
Antibiotics only if secondary infection present
Tetanus vaccination if needed

137
Q

Black widow

general

A

Black widow spider produces a neurotoxin
Characteristic right hourglass shape on the underside of its belly.

138
Q

black widow

Clinical Manifestations

A

Typical progression: localized pain at the bite site with the onset of systemic and neurologic symptoms within 30 minutes to 2 hours after bite
Muscle pain is most common symptom, typically in the extremities, abdomen, or back
Spasms and rigidity possible
Classic appearanceblanched circular patch with erythematous perimeter and central punctum

139
Q

black widow

Tx

A

Usually self limited, tends to resolve within 1 to 3 days.
Wound care and pain and spasm control
Most wounds heal spontaneously with adequate cleansing
Pain control: NSAIDs are mostly commonly used
Muscle relaxants for spasm - benzodiazepines
Antivenom - reserved for refractory symptoms.
Tetanus vaccination if needed

140
Q
A

black widow bite

141
Q
A

cellulitis

142
Q

cellulitis

general and agents

A

Results from an infection of the dermis that often begins with loss of integrity of the skin
80% of cases are caused by Gram - Positive organisms (Group A Strep)
Staphylococcus aureus - IV drug use
MRSA - purulent drainage present
Pasteurella multiocida - animal bites

143
Q

cellulitis

risk factors

A

Local trauma - insect/animal bite, laceration, abrasion, puncture wound
Spread of a preceding or concurrent skin lesion - furuncle, ulcer
Pre-existing skin infection due to compromised skin barrier
Edema and impaired lymphatics in the affected area

144
Q

cellulitis

clin man

A

Spreading erythematous, non-fluctuant, tender, poor-defined plaque
Tends to occur on lower extremities

145
Q

cellulitis

Tx

purulent vs not

A

Non-purulent cellulitis:
Cephalexin, amoxicillin, amoxicillin- clavulanate (animal bites), or clindamycin

Purulent cellulitis:
Clindamycin, TMP/SMX, doxycycline + amoxicillin
General measures - elevation of extremity, cool compresses

146
Q

Erysipelas

general

A

Superficial cellulitis with marked dermal lymphatic involvement - causes edema
Main pathogen: Group A Streptococcus
Others: S. aureus, Haemophilus

147
Q

Erysipelas

Clin Man

A

Usually affects face, lower extremities
Painful, bright red erythematous, plaque-like edema with sharp margin
May develop bullae
Can be associated with high WBC count (>20,000/mcl)
Can have associated fever, chills, headache, vomiting, joint pain

148
Q
A

Erysipelas

reactive erythema

149
Q

Erysipelas

Tx

A

Empiric antibiotic therapy - penicillin V, amoxicillin, clindamycin, azithromycin
Elevation of involved area
Monitor patients closely

150
Q

Lymphangitis

general

A

Inflammation of lymphatic channels due to infectious or non infectious causes
Pathogens include bacteria, viruses, fungi, and parasites - typically introduced through a skin wound or as a complication of a distal infection.

151
Q

Lymphangitis

clin man

A

Red, tender streaks extending proximally from a site of cellulitis
May have lymphadenopathy or systemic symptoms such as fever and chills

152
Q
A

Lymphangitis

153
Q

Lymphangitis

Tx oral and IV
MRSA pal and IV

A

Oral: cephalexin, dicloxacillin. Erythromycin or Clindamycin if penicillin allergy
IV: cefazolin, ampicillin-sulbactam, ceftriaxone + Clindamycin

MRSA:
Oral: TMP-SMZ+cephalexin
IV: vancomycin
