A 77 YO man w/a history of peripheral arterial disease presents w/a nonhealing ulcer on his right ankle. The wound is dry & exhibits signs of poor perfusion, such as coolness and pallor. Based on evidence-based protocols, what should be the initial approach to improve healing?
Compression therapy
Ensuring a dry wound environment
HBOT
Revascularization assessment and vascular consultation
Revascularization assessment and vascular consultation
* Peripheral arterial disease reduces blood flow to the extremities. A non healing ulcer in this context results from insufficient perfusion; thus, revascullarization is crucial to restore circulation.
What is the purpose of hydrogel dressings in the management of superficial partial-thickness burn wounds?
Providing antimicrobial properties
Increasing moisture in the wound bed
Enhancing hemostasis
Absorbing heavy exudate
Increasing moisture in the wound bed
* Hydrogel dressing are designed to maintain a moist wound environment, which is crucial for the healing of superficial partial-thickness burns. This moisture promotes autolytic debridement, where the body's natural enzymes break down dead tissue, and encourages epithelial cell migration across the wound bed. - A moist environment also helps reduce pain and prevents dehydration.
______ accelerates wound healing by promoting tissue perfusion and removing excess exudate
NPWT
Which of the following symptoms is present with an ankle-brachial index (ABI) of 0.60?
Sever claudication pain
No symptoms
Mild claudication pain
Rest pain
Mild claudication pain
ABI =0/60 indicates moderate peripheral arterial disease and is typically associated w/intermittent (extertional) claudication, not rest pain. Use non-overlapping ranges to avoid ambiguity: \n* 1.00-1.30; Normal /n* 0.90-0.99
Toxic epidermal necrolysis (TEN) -
Is a rare, life-threatening skin condition characterized by widespread blistering, peeling, and detachment of the epidermis over more than 30% of the body. It is most commonly triggered by an adverse reaction to medications such as antibiotics, anticonvulsants, and allopurinol.
Toxic epidermal necrolysis signs and symptoms -
- High fever, cough, and painful flu-like aches starting one to four weeks after taking a new drug
- A red or purplish rash that spreads quickly across the face and upper body
- Large blisters and raw, weeping areas where the top layer of skin separates from the lower layer
- Severe sores, swelling, and crusting in mucous membranes including the mouth, eyes, and genitals
Which of the following interventions is indicated in the treatment of toxic epidermal necrolysis (TEN)?
Parenteral nutrition
Empiric prophylactic antibiotics
Ophthalmologic consultation for ocular manifestations
Innunoglobulin-G with sucrose
Ophthalmologic consultation for ocular manifestations
RE: Interventions for TEN:
is a rare but severe exfoliative DO characterized by widespread peidermal detachment. Up to 80% of cases are drug-induced, w/Stevens-Johnson syndrome representing a milder form
TEN involved more than ___ of the total body surface area & can be life-threatening, often triggered by medications such as ____, or ____
30%
COX- inhibitors (e.g, valdecoxib) or penicillins
Clinically, _______ ___ presents w/diffuse erythema, mmacules that coalesce, and full-thickness epidermal sloughing. Mucosal involvement is common, affecting the oral cavity, eyes, respiratory tract, and genitourinary tract, resulting in painful erosions.
Toxic epidermal necrolysis -TEN
TEN Managment includes:
- Immediate discontinuation of the offending drug
- Supportive care in the specialized burn unit (temperature control, fluid and electrolyte managment, nutritinal support)
- Wound care to prevent infection & promote re-epithelialization
- - Prefer enteral over parenteral nutrition
- Intravenous immunoglobulin G (IgG) may be considered; avoid preparations containing sucrose
- Systemic prophylactic antibiotics are not routinely recommended
- Ophthalmologic consultation is essential to assess & manage ocular complications.
What is a hallmark sign of toxic epidermal necrolysis?
Nikolsky's sign.
* Slight thumb pressure applied to intact skin adjacent to blisters causes the epidermis to shear laterally, producing a wrinkling of the skin & indicating a positive Nikolsky's sign.
Crowe's sign
Axillary frecling seen in neurofibromatosis type I.
Developement of erythema, swelling, and pruritus after stroking lesions in systemic mastocytosis or urticaria pigmentosa.
Darier's sign
Pinpoint bleeding when scales are scraped from psoriatic plaques.
Auspitz's sign
__________ phase is characterized by the rapid growth of epithelial cells, the formation of new blood vessels (angiogenesis), and collagen synthesis, all of which are esential for rebuilding damaged tissue.
...
healthy, clean wounds should be cleansed with _____ _____ rather than antimicrobial solutions of skin cleansers
Normal Saline
Medical-grade honey is indicated for use inn infected wounds. How does honey inhibit bacterial action?
There is a low concentration of slow-release hydrogen peroxide naturally produced in honey that inhibits bacterial growth.
Factors that increase the risk of fistula formation include:
- Steroid use
- Inflammatory bowel disease (IBD
- Radiation therapy
- Creation of an enterostomy
- Poor nutrition
- Hypoxia (reduced oxygen supply)
- Diabetes Melitus
- Liver cirrhosis
- Chemotherapy
- Use of anti-inflammatory medications
- Sepsis
- Gastrointestinal surgery w/out adequate bowel preparation
