PANCE Blueprint Dermatology (4%)

Skin integrity (Pearls)

The NCCPA™ PANCE Dermatology Content Blueprint includes three disorders under the skin integrity category, with diabetic ulcers also addressed within the PANRE blueprint for comprehensive coverage.

Burns

Patient will present as → a 35-year-old male who was throwing some paint thinner on fire to get it going a little better when it splashed on him and caught his R arm and his R hip area on fire. He did not have pain right away and was not going to go to the hospital. He washed off the burnt areas because he had grease and oil on his hands and lower arm. The pain then started to get bad enough for him to have his wife take him to the ER.

Body percentage:

  • Rule of 9’s: Head 9%, Each arm 9%, Chest 9%, Abdomen 9%, Each anterior leg 9%, Each posterior leg 9%, Upper back 9%, Lower back 9%, Genitals 1%
  • Palmar method: Patient’s palm equates to 1%

Degree involvement:

Treatment: Monitor ABCs, fluid replacement, and sulfadiazine. Children with > 10% total body surface area and adults with > 15% total body surface area burns need formal fluid resuscitation

Diabetic ulcers

Patient will present as → a 64-year-old male with poorly controlled type 2 diabetes presents with a non-healing plantar foot ulcer and foul-smelling drainage for two weeks. Exam reveals a 2.5 cm necrotic ulcer with surrounding erythema and reduced foot sensation. Pulses are diminished. Labs show leukocytosis and HbA1c of 10.2%. He is diagnosed with an infected diabetic foot ulcer. Management includes broad-spectrum antibiotics, wound debridement, offloading with total contact cast, and tight glycemic control. Imaging is obtained to rule out osteomyelitis, and he is referred to podiatry and vascular surgery.

 Diabetic ulcers are chronic, non-healing wounds, typically on the feet, caused by neuropathy, poor circulation, and impaired immunity in diabetic patients

  • Plantar surface, metatarsal heads, heels, and pressure points are common sites
  • Risk factors include peripheral neuropathy, PAD, foot deformities, poor footwear, prior ulcers, and poor glycemic control
  • Often painless, with surrounding callus, erythema, swelling; may show infection (purulence, odor) or signs of osteomyelitis
  • DX: Clinical exam, probe-to-bonemonofilament testing, cultures if infected, X-ray/MRI for osteomyelitis, ABI (may need toe pressures if falsely elevated)
  • TX:
    • Wound care: Debridement, moist dressings
    • Offloading: Total contact cast or protective footwear
    • Antibiotics: Empiric, then culture-directed
    • Glycemic control: Essential for healing
    • Revascularization: If PAD is severe
    • Surgery: For deep infection, gangrene, or nonresponse
  • Complications: Osteomyelitis, cellulitis, gangrene, amputation
  • Prevention: Daily foot checks, podiatric care, proper shoes, tight glucose control

Lacerations

Patient will present as → a 27-year-old male who arrives at your clinic after sustaining a laceration to his right thumb while cutting a bagel. He was able to stop the bleeding after about 2 minutes with gentle pressure. Physical exam reveals a 2 cm laceration on the finger pad of the right first digit that approximates easily with gentle pressure.

Suture removal — The timing of suture removal varies with the anatomic site

  • Eyelids – Three days
  • Neck – Three to four days
  • Face – Five days
  • Scalp – 7 to 14 days
  • Trunk and upper extremities – Seven days
  • Lower extremities – 8 to 10 days

Follow-up visits — Most clean wounds do not need to be seen prior to removal unless signs of infection develop. Highly contaminated wounds should be seen for follow-up in 48 to 72 hours. It is imperative that clear discharge instructions are given to every patient regarding signs of wound infection.

Nonabsorbable sutures
Suture material Knot security Wound tensile strength Tissue reactivity Workability Anatomic site
Nylon (Ethilon) Good Good Minimal Good Skin closure anywhere
Polybutester (Novafil) Good Good Minimal Good Skin closure anywhere
Polypropylene (Prolene) Least Best Least Fair Skin closure anywhere. Blue dyed suture useful in dark-skinned individuals.
Silk Best Least Most Best Rarely used
Absorbable sutures
Suture material Knot security Wound tensile strength Security (days)* Tissue reactivity Anatomic site
Fast-absorbing gut Poor Least 4 to 6 Most Face
Vicryl Rapide Good Fair 5 to 7 Minimal Face, scalp, undercast/splint
Surgical gut Poor Fair 5 to 7 Most Face (rarely used)
Poliglecaprone 25 (Monocryl) Good Fair 7 to 10 Minimal Face, consider in contaminated wounds needing deep closure
Chromic gut Fair Fair 10 to 14 Most Mouth, tongue, nailbed
Polyglactin (Vicryl) Good Good 30 Minimal Deep closure, nailbed, mouth
Polyglycolic acid (Dexon) Best Good 30 Minimal Deep closure
Polydioxanone (PDS) Fair Best 45 to 60 Least Deep closure
Polyglyconate (Maxon) Fair Best 45 to 60 Least Deep closure
* Retention of 50 percent of tensile strength.

Most wounds should be covered with an antibiotic ointment and a nonadhesive dressing immediately after laceration repair

  • The dressing should be left in place for 24 hours, after which time most wounds can be opened to air.

Prophylactic antibiotics may decrease the risk of infection in some animal and human bites, intraoral lacerations, open fractures, and wounds that extend into cartilage, joints, or tendons 

  • Allow animal bites, especially in non-cosmetic areas such as the hand and foot are to heal by secondary intention

Pressure ulcers

Patient will present as → an 80-year-old bed-bound woman with a temperature of 104°F who you are called to see in the nursing home. The patient is disoriented and confused. On physical examination, the patient’s blood pressure is 110/ 80 mm Hg, and her pulse is 72 beats/ minute and regular. There is an 8 × 5 cm pressure ulcer over her sacrum. Also, there is a purulent, foul-smelling discharge coming from the ulcer.

The sacrum and hip are most often affected. Reposition every 2 hours

  • Stage 1: erythema of localized area, usually non-blanching over the bony surface
  • Stage 2: partial loss of dermal layer, resulting in pink ulceration
  • Stage 3: full dermal loss, often exposing subcutaneous tissue and fat
  • Stage 4: full-thickness ulceration exposing bone, tendon, or muscle. Osteomyelitis may be present

Wound management by stage of the ulcer

  • Stage I: aggressive preventive measures, thin-film dressings for protection
  • Stage II: occlusive dressing to maintain healing, transparent films, hydrocolloids
  • Stages III-IV: Debridement of necrotic tissue. Exudative ulcers will benefit from absorptive dressings such as calcium alginates, foams, and hydrofibers. Dry ulcers require occlusive dressing to maintain moisture, including hydrocolloids, and hydrogels.

Risk factors: age >65, impaired circulation, immobilization, undernutrition, incontinence

DX: based on observation and staged according to classification

TX: debridement ⇒ depends on the extent of necrosis; surgical closure may be necessary; vacuum-assisted closure uses negative pressure to reduce wound edema and remove debris/reduce bacterial load
