​Kembara Xta - Medicine - Stasis Dermatitis 
Introduction: Patients with chronic venous insufficiency (CVI) may experience nutritional edema, which is characterized by chronic, eczematous, erythematous, scaling, and noninflammatory edema of the lower extremities that is accompanied by a cycle of scratching, excoriations, weeping, crusting, and inflammation. 
Clinical cutaneous manifestation of CVI can occur as a solitary lesion and is frequently accompanied with venous leg ulcers that are on the medial or lateral side of the ankle. 
Systems impacted: exocrine and/or cutaneous
Synonym(s): venous dermatitis, varicose eczema, and gravity eczema

Incidence and prevalence in Epidemiology 

Incidence In the United States, patients over 50 are more likely to develop it (6-7%).
Adults and elderly people make up the majority of the population.
Female is more prevalent than male.
Geriatric Considerations

Typical for this age group:
Affects 15 to 20 million patients in the US who are over 50 years old.

Pathophysiology and Etiology 
Varicose veins' superficial venous thrombosis, deep vein thrombosis (DVT), and ineffective perforating veins can all cause venous hypertension (HTN) and cutaneous irritation as a result of CVI. This might lead to a venous leg ulcer.
Fibrin deposits around capillaries 
Microvascular deviations

Ischemia, persistent ankle edema typically brought on by varicose veins, weak venous walls in the lower legs, and all of the above.
Trauma to edematous, eczematized skin Itching may be brought on by inflammatory mediators released in the endothelium and microcirculation by mast cells, monocytes, macrophages, or neutrophils.
Ulceration is caused by a series of biochemical processes, one of which is a cascade of abnormal leukocyte-endothelium interaction.
Genetics
Family connection likely


Risk factors include: itch-scratch cycle superimposition; atopy; chronic edema; old age; obesity; previous pregnancy; prolonged standing; low protein diet; genetic predisposition; tight clothing that constricts the thigh; vein stripping; vein harvesting for coronary artery bypass graft surgery; and prior cellulitis.

Prevention 

Use compression stockings to prevent the edema from returning and to move the interstitial lymphatic fluid away from the area where stasis dermatitis has developed as well as after DVT.
To stop tearing and itching, apply topical lubricants twice daily.


Varicose veins, venous insufficiency, other eczematous diseases, hyperhomocysteinemia, and venous hypertension are associated conditions.

Skin indications, which are worse in the nighttime hours, may be preceded by itching, discomfort, and burning.
Insidious beginning
Legs may be ached or heavy in the description, which is typically bilateral.
Lower extremity erythema, scaling, and oedema
The skin eruption and ulceration were preceded by non-inflammatory edema, which first appears around the ankle.

clinical assessment 
An assessment of the lower extremities typically reveals: - Bilateral plaques, papules, or scaly, eczematous areas
- Violaceous (occasionally brown), erythematous lesions resulting from venous blood that has not been properly oxygenated (post-inflammatory hyperpigmentation and hemosiderin deposition in the cutaneous tissue)
Stasis ulcers (which usually accompany stasis dermatitis) owing to slight trauma are distributed in the medial portion of the ankle, frequently extending onto the foot and lower leg.
Excoriations, weeping, crusting, and skin irritation are all symptoms of ulcers, and varicosities are frequently present.
Clinical examination reveals warmth and edema, and skin alterations are more frequent medially and in the lower third of the extremity.
Early symptoms include large superficial veins and pitting ankle edema. A single lesion that resembles a tumor may also be present.


Differential diagnosis: Additional eczematous conditions
- Contact dermatitis (caused by topical medications used for self-treatment) - Atopic dermatitis - Uremic dermatitis
- Skin ulceration brought on by Sickle cell disease; - Neurodermatitis; - Arterial insufficiency
• Cellulitis
- Xerosis, erysipelas, Tinea dermatophyte infection, Nummular eczema, Lichen simplex chronicus, Asteatotic eczema, and Amyopathic dermatomyositis

Laboratory Results 
Initial examinations (lab, imaging)
Diagnostic use of duplex ultrasound imaging is beneficial.


Other/Diagnostic Procedures
Distinguish arterial insufficiency. Verify the ankle brachial pressure index (ABPI or ABI) and check the peripheral pulses for diabetes.

Interpretation of Tests
ABPI values below 0.8 are indicative of arterial insufficiency.
The gold standards for diagnosing distal small artery calcifications are arterial duplex ultrasonography and angiography. ABPI can be increased, >1.2 in diabetic individuals and others.

Prevention 
Reversing the consequences of venous HTN is the primary goal of treatment. 
Suitable medical care: 
Acute care:
- Reduce swelling:
Leg elevation involves raising your legs three to four times a day for a total of 30 minutes. Stay away from a long-term reliant status.
Compression therapy is the cornerstone therapy for venous stasis ulcers. Patients with an ABI of 0.8 to 1.2 can safely use compression bandages.
Ace bandages, Unna paste boots (zinc gelatin), or compression stockings are examples of elastic bandage wraps.
The ankle can benefit from graduated elastic compression of 30 to 40 mm Hg to speed up ulcer healing and perhaps prevent ulcer recurrence (1)[A].
○ Mixed component systems, which are compression bandages with both elastic and inelastic components, are just as effective as four-layer bandages, but they are also simpler to apply, have less slippage, and have positive effects on quality of life.
High compression should not be used in cases with arterial insufficiency.
In nonambulatory patients and those who have a component of arterial insufficiency, pneumatic compression devices are helpful.

Lipodermatosclerosis improvement: - Action:
Avoid remaining motionless.
 Keep moving and work out frequently.
Unless it is prohibited, raise the foot of the bed.
Inpatient, for skin grafts, vein stripping, sclerotherapy, or endovascular radiofrequency ablation: - Treatment for venous ulcers: Infection treatment: Remove any necrotic tissue from the ulcer base by performing a surgical necrotomy, if possible, or by using collagenase for enzymatic débridement.
In comparison to traditional wet to dry dressings, modern wound dressings (hydrogel, hydrocolloids, alginate, foam bandages, basic nonadherent dressing) maintain a moist wound environment while causing less tissue damage upon removal and requiring less frequent replacement.
However, when utilized beneath compression, hydrocolloid dressing has no effect on the rate at which venous stasis ulcers heal in comparison to a straightforward nonadherent dressing.
Biological: Topical granulocyte-macrophage colony-stimulating factor treatment speeds ulcer healing (inadequate evidence).
 Mechanical: irrigation, hydrotherapy, and wet to dry dressings
Surgery can be used to cure ulcers and change the etiology of venous hypertension (by venous ligation, valvuloplasty, and endoscopic perforator vein surgery).

First Line of Medicine
Treatment of venous leg ulcers with pentoxifylline 400 mg TID is successful.
Low-dose aspirin use is advised because adjuvant therapy for venous leg ulcers is unsupported.
Current recommendations advise using antibacterial treatments only for clinical infection (cellulitis, increased discomfort, warmth, and malodorous discharge), not for bacterial colonization, due to the rise in bacterial resistance to antibiotics.

If secondary infection occurs, administer oral Staphylococcus or Streptococcus antibiotics (e.g., dicloxacillin 250 mg QID, cephalexin 500 mg BID, or levofloxacin 500 mg daily).
Clindamycin 300 mg QID, doxycycline 100 mg BID, TMP/SMX, or IV vancomycin should be used if MRSA is suspected.
Topical antiseptics such povidone-iodine, preparations based on peroxide, mupirocin, and chlorhexidine have not been proven to be efficacious, according to trustworthy research.
Short courses (approximately 2 weeks) of topical steroids (topical triamcinolone 0.1% cream/ointment BID) can be used to treat uncomplicated stasis dermatitis.
Topical anesthetics (lidocaine/prilocaine) may lessen discomfort during débridement. Topical antipruritics: pramoxine, camphor, menthol, and doxepin.
Systemic steroids for serious conditions
Silver sulfadiazine (SSD) promotes the healing of wounds.

Next Line
Based on the findings of a culture of exudate from infected ulcer craters, antibiotics may be considered.
Lubricants for quiescent dermatitis 
Topical emollients (such lanolin and white petroleum jelly) can be used to treat chronic stasis dermatitis.
There is no proof that ibuprofen dressings provide pain relief; antipruritic drugs (such as diphenhydramine and cetirizine hydrochloride) and hydrocolloid or a foam dressing may lessen ulcer discomfort.

Problems to Refer 
Consider making a referral if you have a non-healing ulcer, arterial insufficiency, rheumatoid arthritis, an uncertain diagnosis, contact dermatitis, or an associated condition (such bothersome varicose veins).

Further Treatments 

Consider stopping amlodipine if the patient is taking it.

Surgical Techniques 

Surgery and sclerosing therapy may be necessary for the related disease.

Patient Follow-Up Monitoring

 Once a week, cut off and reapply the boot if Unna boot compression is being used. Unna boots minimize itching and reduce edema through compression.
High-compression stocking use on a regular basis lowers the risk of recurrent venous ulcers (5).[A].
DIET If you're overweight, lose weight.
Encourage staying active to maintain healthy circulation and strong leg muscles. The best is to walk.
When sitting or lying down, keep your legs raised.

Avoid wearing garters, girdles, or pantyhose with tight elastic tops, and avoid scratching.
Prevent leg injuries.
With 2- to 4-inch blocks, raise the foot of the bed.
When there is less edema, put on compression stockings before getting out of bed. High-compression stockings can help prevent venous ulcers from returning on a regular basis.

Prognosis Chronic course with sporadic exacerbations and remissions The ulceration healing process is frequently drawn out and may take months.

Complications Itching, discomfort, and burning sensations have a negative effect on a person's quality of life.
Bleeding at dermatitis spots DVT Secondary bacterial infection
Long-standing stasis ulcers' borders may have squamous cell carcinoma. Scarring may also increase the risk of minor trauma and further limit blood flow.
