Ulcers In The Legs Or Feet

Signs Of An Infection

A venous leg ulcer can be susceptible to bacterial infection. Symptoms of an infected leg ulcer can include:

• worsening pain

A number of factors can increase your risk of developing a venous leg ulcer, including:

• obesity or being overweight this increases the pressure in the leg veins
• if you have difficulty walking this can weaken the calf muscles, which can affect circulation in the leg veins
• previous deep vein thrombosis blood clots that develop in the leg can damage valves in the veins
• varicose veins swollen and enlarged veins caused by malfunctioning valves
• previous injury to the leg, such as a broken or fractured bone, which may cause DVT or impair walking
• previous surgery to the leg, such as a hip replacement or knee replacement, which can prevent you from moving about
• increasing age people find it harder to move around as they get older, particularly if they suffer from arthritis

C Data Abstraction And Data Management

Two independent reviewers will conduct title scans. For a title to be eliminated at this level, both reviewers will need to indicate that the study was ineligible. If the reviewers disagree, the article will be advanced to the next level, which is abstract review.

The abstract review phase will be designed to identify studies reporting the effects of treatment options for chronic venous leg ulcers. Abstracts will be reviewed independently by two investigators and will be excluded if both investigators agree that the article meets one or more of the exclusion criteria . Differences between investigators regarding the inclusion or exclusion of abstracts will be tracked and resolved through consensus adjudication.

Articles promoted on the basis of the abstract review will undergo another independent parallel review to determine if they should be included in the final qualitative and quantitative systematic review and meta-analysis. The differences regarding article inclusion will be tracked and resolved through consensus adjudication.

We will use a systematic approach to extract all data to minimize the risk of bias in this process. We will create standardized forms for data extraction, which will be pilot tested. By creating standardized forms for data extraction, we seek to maximize consistency in identifying all pertinent data available for synthesis.

What Is An Ulcer

When your stomachâs healthy, itâs coated in a layer of sticky mucus. This protects it from the harsh acid that breaks down your food. If something upsets this balance, you end up with more stomach acid and not enough mucus. Over time, that acid gnaws away at the tissue that lines your stomach. The painful and sometimes bloody open sore it causes is called an ulcer. Some are tiny, while others are over an inch long.

How Venous Leg Ulcers Are Treated

Most venous leg ulcers heal within 3 to 4 months if they’re treated by a healthcare professional trained in compression therapy for leg ulcers.

But some ulcers may take longer to heal, and a very small number never heal.

Treatment usually involves:

• cleaning and dressing the wound
• using compression, such as bandages or stockings, to improve the flow of blood in the legs

Antibiotics may also be used if the ulcer becomes infected, but they do not help ulcers heal.

But unless the underlying cause of the ulcer is addressed, there’s a high risk of a venous leg ulcer coming back after treatment.

Underlying causes could include immobility, obesity, previous DVT or varicose veins.

What Causes Wound Infections

Your skin protects your body from various pathogens. A wound is an opportunity for bacteria and other microorganisms to enter your body and cause problems like inflammation and tissue damage. An infection can start in a wound within a couple of days. The risk of infection is present until the wound heals.

How Should I Treat A Leg Infection

The most appropriate treatment for a leg infection depends on the particular type of infection. Some affect a persons skin cells while others may involve the bone or lymph nodes. If a person suspects he has an infected leg, he should see a doctor for a diagnosis and treatment recommendation. Some seemingly minor infections can become severe if left untreated or if theyre treated with the wrong types of medication.

One type of infection that may affect a persons leg is called cellulitis. This infection involves the cells right below the skins surface, causing inflammation in the affected area. It develops when the skin is broken, such as because of a cut, broken blister or animal bite. The broken skin allows bacteria to enter the body, which leads to the infection. There are many types of bacteria that cause cellulitis, but those in the strep family are the most common.

Oral antibiotics are usually used to treat a cellulitis leg infection and usually cure it within a week or so. A patient may return to his doctor after about a week to check whether it has gone away entirely. In a severe case, a person may need to be hospitalized and treated with intravenous antibiotics.

How Do Wounds Occur

Wounds occur when the skin is broken or damaged through injury or surgical incision. The skin can be damaged in a variety of ways depending on the cause of the injury e.g. trauma pressure or friction . The lower limbs in particular can be prone to diabetic and venous ulcers which may have started with trauma or through repeated irritation which combined with poor blood circulation results in skin damage.

Was The Allocation Sequence Randomly Generated

Low risk of bias

The investigators describe a random component in the sequence generation process such as: referring to a random number table using a computer random number generator coin tossing shuffling cards or envelopes throwing dice drawing of lots.

High risk of bias

The investigators describe a nonrandom component in the sequence generation process. Usually, the description would involve some systematic, nonrandom approach, for example: sequence generated by odd or even date of birth sequence generated by some rule based on date of admission sequence generated by some rule based on hospital or clinic record number.

Hypertensive Ulcer Synonymous Martorell’s Ulcer

In hypertension, the density of the capillary beds in the middle and deep dermis of the skin particularly of its lateral aspect is much reduced, which may predispose to ischaemic necrosis when the sparse arterioles are subjected to severe hypertension.Hypertension produces superficial ulceration, when peripheral pulses are always present, distinguishing the condition from peripheral vascular disease.

Other Types Of Leg Ulcer

Other common types of leg ulcer include:

• arterial leg ulcers caused by poor blood circulation in the arteries
• diabetic leg ulcers caused by the high blood sugar associated with diabetes
• vasculitic leg ulcers associated with chronic inflammatory disorders such as rheumatoid arthritis and lupus
• traumatic leg ulcers caused by injury to the leg
• malignant leg ulcers caused by a tumour of the skin of the leg

Most ulcers caused by artery disease or diabetes occur on the foot rather than the leg.

Diabetic Foot Ulcer Risk Factors

Anyone with diabetes is at risk of a foot ulcer. People with neuropathy, poor glycemic control, and vascular disease are considered high-risk for ulcers and associated complications.

• insulin use
• obesity

To be fully informed of your risk, speak with a podiatrist to test for neuropathy. As nerve damage can occur without pain, your podiatrist can test your feet with a simple, painless tool called a monofilament. Patients who are unable to feel the monofilament are insensate and are 10 times more likely to develop a foot ulcer than their sensate counterparts.

Natural Treatment For Arterial And Venous Ulcers

As mentioned in other texts, the body has a surprising healing ability. It is capable of self-repair, self-balance, and self-renovation, if we just give it the necessary elements for healing.

A lot of times, medications prevent the body from this ability because chemicals do the work that the body and the defense system should do. They might be able to help control a few symptoms, but they wont truly cure the cause, which makes the body need more and more medications, or a larger dose for healing.

If you have taken medications, however, and you want to begin a natural treatment, it is not in your best interests to stop using the medication, because this could unbalance your body , which has grown used to reacting with medicines. Its best to alternate your medication with natural treatments, and see a naturopath who can help determine when to reduce, or even stop using your medications.

You also need to trust deeply in your bodys healing powers, which will undoubtedly start to respond if you give it the necessary elements.

About Foot And Leg Wounds And Ulcers

Most of the time, leg ulcers cause pain. If, however, you get leg ulcers due to nerve problems , you may not feel any pain. And because there is no pain, people tend to ignore the ulcer, which can lead to a leg infection.

In addition to non-healing wounds and pain, you may also have these symptoms in your legs:

• Heaviness
• Change of color

There are several types of foot and leg wounds and ulcers.

• Venous ulcers are the most common type of foot and leg wounds and ulcers. They usually affect people with varicose veins or deep vein clots. They usually affect the inner part of the leg, above the ankle and may be irregularly shaped, reddish, and covered with yellow fibrous tissue. They also might have discharge.
• Arterial ulcers affect people who have poor circulation, high blood pressure, diabetes, or are smokers. These ulcers usually appear on the outer part of the leg and on the heels, tips of toes, and between the toes where the toes rub against each another. These ulcers vary in color and do not bleed. Often, patients report decreased pain after they dangle their feet over the edge of the bed.
• Neurotrophic ulcers/diabetic ulcers affect people who are diabetic, have nerve problems in their feet, or have had some sort of trauma to their legs or feet. These ulcers usually appear on the heels at the pressure points and may bleed. The surrounding skin is typically calloused.

• Diabetes mellitus
• Infections

Why Does Diabetes Affect Your Feet

High blood sugar levels lead to nerve damage, especially in the feet and lower legs. Diabetic neuropathy prevents a patient from feeling sores, cuts, blisters, or other damage to the feet. Neuropathic ulcers occur due to the loss of feeling in the feet unnoticed cuts or sores are left untreated to become more severe ulcers.

Diabetes also causes blood vessels in the feet and legs to narrow and harden, decreasing blood flow. People with type 2 diabetes are also at risk for peripheral arterial disease . With PAD, buildup on the walls of blood vessels causes them to narrow. Poor blood flow in the feet inhibits the healing of injuries and increases the risk of diabetic foot infections.

The combination of diabetic neuropathy and poor circulation put diabetics at higher risk for infections and more serious foot problems such as Charcot foot deformities, gangrene, bone infections , and even amputation.

What Are Foot And Toe Ulcers

An ulcer is an open wound or sore that will not heal or keeps returning. When you have ulcers on your feet and toes, it can be related to diabetes specifically, a complication called neuropathy that causes you to lose feeling in your feet. A scrape, cut or puncture in your skin can turn into an ulcer, but you might not know its there if you have neuropathy.

Ulcers can lead to infections. Sometimes, the infection wont go away and you may need to have part of your foot or toe surgically removed . About 15% of people with diabetes will get a foot or toe ulcer. Around 14% to 24% of people with diabetes in the U.S. need an amputation after they get an ulcer.

Treatment Of Leg Ulcers

Assessment of a patient with leg ulcer consists of the following:

• Comprehensive clinical history and physical examination in order to determine the aetiology of the ulcer.

• Doppler measurement of the pressure at the ankle and brachial artery to determine ankle:brachial pressure index .

• The wound size and shape must be documented either by measuring the length and width of the ulcer by tracing onto an acetate sheet or by photographic record.

• The ulcer should be swabbed for microbiology.

• Full blood count, random blood sugar, chemical profile, and plasma viscosity should be done.

• Ulcers of unusual appearance should be biopsied.

• Deep ulcers should have plain radiography of the affected areas and computed tomography, magnetic resonance imaging, etc to exclude osteomyelitis, especially in chronic non-healing ulcers.

• Patch tests may be indicated if there is an extensive eczema or local allergy.

Treatment What Treatment Will I Be Offered For My Leg Ulcer

Compression therapy

If your wound isnt healing because of venous hypertension and there are no problems with the blood supply to your legs, then you should be offered compression therapy.

Compression therapy improves blood supply by applying pressure to the leg. This can be done by bandaging the lower leg or by wearing supportive socks, stockings or tights. Compression therapy is very effective at reducing swelling, improving blood flow in the veins and healing or preventing sores or ulcers.

There are lots of different types of compression therapy so ask your nurse to find something that is right for you.

Compression can be a little uncomfortable when you first start treatment but should not cause you any pain. Any discomfort should reduce as the swelling goes down. If you do experience discomfort, talk to your nurse or doctor about it and they will advise you on ways of alleviating this.

In addition to the compression, your nurse should also advise you on wound care and dressings to keep your wound healthy.

Were Incomplete Outcome Data Adequately Addressed

Low risk of bias

Any one of the following:

• No missing outcome data.
• Reasons for missing outcome data unlikely to be related to true outcome .
• Missing outcome data balanced in numbers across intervention groups, with similar reasons for missing data across groups.
• For dichotomous outcome data, the proportion of missing outcomes compared with observed event risk not enough to have a clinically relevant impact on the intervention effect estimate.
• For continuous outcome data, plausible effect size among missing outcomes not enough to have a clinically relevant impact on observed effect size.
• Missing data have been imputed using appropriate methods.

High risk of bias

Any one of the following:

• Reason for missing outcome data likely to be related to true outcome, with either imbalance in numbers or reasons for missing data across intervention groups.
• For dichotomous outcome data, the proportion of missing outcomes compared with observed event risk enough to induce clinically relevant bias in intervention effect estimate.
• For continuous outcome data, plausible effect size among missing outcomes enough to induce clinically relevant bias in observed effect size.
• âAstreatedâ analysis done with substantial departure of the intervention received from that assigned at randomisation.
• Potentially inappropriate application of simple imputation.
