A century since the First World War, gangrene remains a problem, albeit a less deadly problem, for many people. The distinctive smell of that "gas gangrene" was the only means to diagnose the condition in the trenches and on the battlefield.
Use this page to learn about the modern-day factors that lead to different forms of gangrene, and how doctors today manage the conditions.
Gangrene is a serious, sometimes life-threatening condition in which the skin, muscle and other tissues die as a result of lost blood supply. It is usually external, affecting the extremities, but it can also affect internal tissues. Gangrene is most commonly associated with chronic illness, such as a severe complication of diabetes, or acute causes, such as certain types of injury.
Dry gangrene is caused by chronic illness, while wet gangrene - including gas gangrene - is usually an acute form involving bacterial infection and caused by injury, for example. Surgical complication can lead to internal gangrene, which presents with signs of toxic shock.
Initial diagnosis is made based on the history leading up to the presentation, and a physical examination, including external appearance and smell.
Urgent treatment is important to prevent further serious illness and death, and includes removal of dead tissue or even amputation. Prevention of gangrene is an important part of living with certain chronic illnesses, including diabetes. Gangrene is a disease of the skin and soft tissues - and sometimes internal tissues and organs - that results in tissue death (necrosis).
Gas gangrene (also called clostridial myonecrosis) is a particularly virulent form of wet gangrene.2,3,6,7 This is the condition that is associated with poorly cleansed wounds of the kind suffered in war - deep crushing or penetrating wounds that become infected with bacteria, Clostridium in particular. The reasons behind necrosis and tissue death differ depending on the specific type of gangrene. Wet gangrene results from a sudden loss of perfusion, and is worsened by the involvement of bacteria.
Dry gangrene is more likely to occur in older people with diabetic foot - a common complication of undiagnosed or uncontrolled diabetes. Complications of diabetes affecting the extremities, especially the feet, are a risk factor for gangrene, partly because painless wounds can go unnoticed.
Surgery - an operation involving the ligation of an artery, as treatment of an aneurysm for example, can shut off blood supply in such a way as to cause gangrene. Mechanical constriction - for example, gangrene can be revealed when pressure splints are removed. Severe burns, scalds and cold - heat, chemical agents (especially carbolic acid, but also caustic potash, and nitric or sulphuric acid), and cold (including frostbite) can all lead to dry gangrene. Raynaud's disease - this condition, in which spasm of blood vessels causes impaired circulation to the ends of fingers and toes, especially in cold weather, is implicated in some cases of gangrene. Eating large quantities of coarse rye bread - long-term intake of ergot, a fungus that can infect rye is implicated in gangrene development as ergotism involves vasoconstriction. Injury - deep, crushing or penetrating wounds that are sustained in conditions that allow bacterial infection to take hold can lead to gangrene. Mechanical constriction - rarely, blood flow restriction caused by pressure from bandages, bone fractures, tumors, and so on, can lead to gangrene. Embolic gangrene - the sudden occlusion of an artery due to an embolism can lead to dry gangrene, but this can also increase the risk of infection and thus lead to wet gangrene. Any case of dry gangrene can progress to wet gangrene if there is an opportunity for bacterial infection. In addition to the features seen in more common types of gangrene, there are certain signs and symptoms peculiar to gas gangrene, a less common form of wet gangrene. Produce a foul-smelling brown-red or bloody fluid when the tissue affected tissue is drained or leaks (a serosanguineous discharge).
Initial suspicion of gangrene calls for physical examination by a doctor, who will also take medical history, asking questions about symptoms and potential exposure to infection or trauma. If gangrene is suspected, further diagnostic tests will be used to determine the type and extent of the necrosis, and to detect or rule out gas gangrene. Olfactory tests - to detect the unique, foul smell that can indicate gangrene, especially gas gangrene. To reduce the risk of serious complication and death, gangrene requires emergency treatment.
In all cases of dry gangrene caused by chronic disease, prevention is far better than cure - simply because cure is not possible after, for example, diabetic gangrene has set in, when amputation of an extremity becomes necessary.5 The same attention to prevention is also important in avoiding the acute risks of gangrene, such as from injury or extreme cold. Hyperbaric oxygen therapy6,9-11 is used in other tissue infections and, in particular, diabetic foot ulcers that have become infected and failed to heal. The idea behind this treatment is that a hyperbaric chamber of high-pressure oxygen creates a bactericidal and bacteriostatic effect and improves oxygen supply to the wounds by encouraging the formation of new blood vessels (angiogenesis), and causing greater dissolution of oxygen in plasma.
In certain settings, such as hospitals, healthcare professionals should practise measures that minimise the risk of infections such as gas gangrene. Frostbite can lead to gangrene, as can Reynaud's, a disease that usually affects the finger tips and tends to be worse in winter. Routinely administering, for abdominal surgery, intravenous antibiotics - before, during, and after the operation.

Learn about pneumococcal disease - an infection caused by a common type of bacteria known as pneumococcus. Lyme disease is caused by the Borrelia burgdorferi bacterium and is transmitted to humans and animals through the bite of infected ticks. Boils also known as skin abscesses are local skin infections that are tender, red and often filled with blood or pus. Diabetic boils are infections which are caused by the weakening of the immune system due to diabetes. Check the blood sugar levels regularly if you have diabetes and make sure that you keep it in check. The skin safeguards our body against microbes and other foreign materials that can harm the body.


Despite these efforts if you have persistent boils then use hot packs and hot soaks to treat the boils.
Genital herpes also called simply as “herpes” is the most common sexual infection affecting millions of people in the USA. Though there is no cure for genital herpes still medications are available for reducing the intensity of its symptoms. HSV-1 is the virus affects your mouth causing cold sores being the symptoms of oral herpes.
In most of the cases genital herpes will not produce any symptoms and if at all they have symptoms it is only mild. The symptoms are self sufficient for detecting genital herpes on physical examination of the genitals.
Mostly, doctors will give antiviral drugs like Acyclovir, Famvir or Valacyclovir for treating genital herpes. Usually the first episode will be severe and recurring episodes would be mild causing mild discomfort. This is a medical term, not a medical condition that is used to describe a type of skin disorder that is very common. Because there are many different kinds of capillaritis there can be a variance of symptoms but in all types there is one common symptom and that is the color of the lesion. In people with dark skin the lesion can be deeply pigmented with pepper-like petechiae, or a red-brown color. The cause of capillaritis could be because of a leakage of the small blood vessels which are called capillaries but in many cases there is no exact cause known. Using certain medication such as non-steroidal anti-inflammatory medications like aspirin, Tylenol, or ibuprofen.
Excessive exercise which can cause capillaritis mainly in your lower legs or ankles and during warm weather may increase in frequency. Treating capillaritis is often not necessary because it will eventually go away on its own.
If is a prescription medication is the cause your physician may suggest stopping the medication temporarily to see if the outbreak will disappear. Glucose tolerance tests help to diagnose type 2 diabetes or impaired glucose tolerance - a condition that may lead to diabetes.
Follow-up laboratory and imaging tests, and sometimes exploratory surgery may also be used to diagnose gangrene. Doctors working in hospitals, especially those involved in abdominal surgery, also take steps to prevent gangrene. In such cases, the circulation of blood to the feet worsens, and there is a higher likelihood of any foot wounds going unnoticed by the patient.
This can also occur in younger people with arteriosclerosis (arterial narrowing) caused by, for example, a combination of syphilis and alcohol dependency.
If treatment involves wet or oily dressings and there are septic conditions, wet gangrene can develop. In gas gangrene the infected area of skin can quickly extend, with some changes visible in just a matter of minutes.
As such, it is important that anyone with suspected symptoms of gangrene seeks immediate medical attention. With treatment, there is a success rate of up to 60%7 (an improvement on the 50% rate achieved on battlefields for the soldiers serving in the World Wars1). However, the precise mechanism behind the effects of hyperbaric oxygen therapy remains unknown. Chicago, Illinois, US: Encyclop?dia Britannica, published online by Encyclop?dia Britannica, Inc, accessed November 2014. They are caused by the staphylococcus aureus bacteria which often enter the skin through wounds and cuts. Unfortunately diabetes can wreck havoc on the immune system and lead to a number of health problems including certain skin complications as well. With high sugar levels the efficiency of the immune system is greatly affected and it can lead to slower healing of wounds and cuts. When there is any break in the skin like cuts or open wounds then it can become infected with bacteria. For larger and painful boils filled with pus you will need to drain the pus and take antibiotics to prevent any bacterial infection. Remember that for taking any medicine for boils it is best to consult a healthcare provider first.
It is the Herpes Simplex Virus that gets transmitted through sexual intercourse from one person to another.
The outbreak of this infection will be high if the immunity of the infected person becomes weak due to hormonal imbalance, stress or any other infection. It will gain entry into the vagina or men’s genital when a person has oral sex with the infected person. There will be mild itching and pain on the genital area few weeks after sexual contact with the infected person. The initial symptoms are observed only after two weeks causing itching of the genitals and redness of the skin. Apart from genital herpes you are inviting risk for getting other sexually transmitted diseases.
Your doctor may request for blood test for detecting the presence of HSV and also viral culture taking the sample tissue from the inflamed area. In case of severe symptoms the infected person will be hospitalized to give antiviral drugs intravenously. In case of suspicion you need to take antiviral medications before 24 hours of initial outbreak. For some it can be 1-2 outbreaks during a year but for others it can be more than 8 outbreaks also.
There can be color variations in the lesion because of the different stages of hemosiderin, which is the re-absorption of the blood breakdown product. When there is a leakage of blood the capillaries become inflamed when the blood passes through the little gaps that occur between the cells that are making up the capillary wall. The rash usually occurs after walking with my local rambling club and I used to think it was caused through wearing gaiters but this is not the case. This is because of diabetic neuropathy, which is a loss of sensation resulting from nerve damage caused by diabetes.
If you have existing boils with pus then drain out the pus by covering the boils with warm cloth, apply antiseptic and cover the boils with bandage. If you have boils and there are clothes that rub against them then make sure that you wear loose fitting clothes that do not rub against wound.


This is because certain immune suppressing medicines used for boils treatment can complicate the problem further. Both men and women are infected with herpes and the main symptoms of herpes are itching and painful sores in the genitals.
Herpes virus gains entry through tiny tears on the skin of the genital organs and travels through the nerve roots finding suitable place in the spinal cord. It takes several weeks or months to develop red blisters or tiny white bumps on the genitals. In addition it may cause inflammation of the cervix (cervicitis) and whitish vaginal discharge.
Pregnant women have increased chance to transmit the infection to the fetus causing more complications for the newborn.
Some doctors may conduct polymerase chain reaction test for detecting the genetic material of the virus. All the treatment given for genital herpes can reduce the symptoms and prevent further infection. You can start using the drug if you feel sudden tingling sensation or indication of formation of sores in the genital area after having sexual contact with some person.
Instead of putting the blame on others you have to take steps for preventing further infection. It is not a harmful condition but it can cause a person who has this skin disorder to feel insecure and embarrassed because of the way it makes you look. Even if a person has no visible sore he can infect virus to others if he carries the virus.
Painful sores can cause inflammation of the cervix and urethra making it difficult to urinate and pass stools.
Taking strong drugs in the initial stage will reduce the risk of transmitting the infection to other partners. Type 1 diabetes is where the body stops making insulin and the blood glucose level goes very high. Capillaritis normally appears in the leg but it can sometimes appear on your upper extremities and trunk but is never present on your face.
Sometime there are no symptoms at all other than the lesions and usually the lesions are non-blanching. People suffering from boils should try to avoid sharing clothes and towels among family members.
Once the virus becomes active it would again travel to the original site of infection causing painful sores and blisters. In rare cases, this infection can travel to your brain through cerebrospinal fluid causing meningitis. Some people who have type 2 diabetes may also need to have insulin injections to help control blood sugar levels. There are some symptoms that are associated with capillaritis that may be managed by using prescription or over-the-counter medications. This skin disorder is normally found in people who work in occupations that require them to stand for long extended periods of time.
If capillaritis is causing itchiness you could apply steroid ointments to help control this problem but it will not shorten the course of the capillaritis outbreak. There are different types of insulin available which are classified according to how quickly and for how long they work. Since capillaritis normally affects your legs, especially the lower portion, wearing compression stocking may help with some the symptoms you are experiencing. Your doctor or diabetes nurse will discuss the various preparations and devices available and help you choose a regimen that is right for you.
If the outbreak is caused by food sensitivities or allergies you may need to start an elimination diet to find the food(s) that is causing the breakouts.
Treatment with insulin is usually lifelong.  What is insulin and how does it work? The most common type of capillaritis is called Schamberg’s disease, which is referred to as progressive pigmented purpura.
So, when your blood glucose level begins to rise (after you eat), the level of insulin should also rise. Insulin works on the cells of your body and makes them take in glucose from the bloodstream. Some of the glucose is used by the cells for energy, and some is converted into glycogen or fat (which are stores of energy). Some glycogen or fat is then converted back into glucose which is released from the cells into the bloodstream. Hormones are chemicals that are released into the bloodstream and work on various parts of the body.
If the blood glucose level remains high despite these measures then tablets to reduce the blood glucose level are usually advised. A glucose tolerance test helps to distinguish between this normal pattern and the patterns seen in diabetes and impaired glucose tolerance. Insulin cannot be taken by mouth, as it is destroyed by the digestive juices in your digestive system. Insulin may come in a vial to be injected with a separate syringe, in a cartridge to be used with an injection device (pen), in a pre-filled injection device, or it can be given continuously by a pump. They are available as vials to be injected with a separate syringe, as a cartridge to be used with an injection device (pen), or in pre-filled injection devices. Before you start treatment your doctor or diabetes nurse will give a lot of advice and instruction on how and when to take the insulin.
An insulin pump may be suitable for people who have lots of 'hypos' (blood sugar becomes very low) or very high blood sugar in the morning, even when on a suitable insulin regimen.
This part can be measured and gives a good indication of your blood glucose control over the previous 1-3 months.
But if you have a lot of hypos or you are unable to tell when you are going to have a hypo then you are not allowed to drive.
You will need to inform the Driver and Vehicle Licensing Agency (DVLA) that your have diabetes and are taking insulin.
