Does peripheral vascular disease cause ulcers,self test for type 2 diabetes yahoo,can type 2 diabetes cause kidney disease - For Begninners

Old age people, individuals with high cholesterol, with high blood pressure, with diabetes, with family history of arthrosclerosis, with smoking habit and obese people are prone to develop peripheral vascular disease. One should follow the instructions of the doctor with respect to diet modifications and lifestyle and take medications as instructed to get maximum benefits. During muscular contraction the bloodflow is blocked, and the O2 tissue tension falls drastically. Ophtalmoscopy for hypertonic changes of the retina also provides the diagnosis hypertension. In some cases of hypertension there is a clear relation to the renin-angiotensin-aldosterone cascade (Chapter 24).
Generalized symmetric distal polyneuropathy is the most common and widely recognized form of diabetic neuropathy leading to diabetic foot ulcer. Autonomic neuropathy is the increased or decreased blood flow to the foot (hot foot) with an increased risk of charcot neuroarthropathy, decreased sweating, dry skin, impaired vasomotion and blood flow. Trauma is frequently the trigger of foot ulcer as repetitive trauma and pressure to the area prevent healing. If the person has history of breakage in skin or wounds in any part of the skin he is prone to cellulitis infection.
Fever, skin rash, hotness in the skin, skin sore and tightened skin is some of the symptoms of cellulitis.
Cellulitis is an infection of the skin and is most often caused by the bacteria Streptococcus or Staphylococcus. If you develop a tender, red, warm, enlarging area on your skin, make an appointment with your physician as soon as possible to get treatment and to avoid complications that may occur if cellulitis is left untreated. Your physician will usually be able to easily diagnose cellulitis by examining the affected area. Opening a blister or pus-filled bump with a needle, scalpel, or lancet after cleansing the skin. Typically, the laboratory will have preliminary results within 48–72 hours if there are many bacteria present. Someone who appears to be very sick or who has other chronic illnesses that may complicate their recovery may need to be hospitalized to receive intravenous antibiotics.

Basically the artery of the major blood vessel gets blocked by plaque like deposits causing blockage in the normal blood flow. Inflammation of blood vessels can occur due to connective tissue damage or injury due to accidents or blood clotting disorders. A person with one or more risk factors given above has increased chances of developing this disease. Some people may have rest pain when there is not enough blood supply to the extremities (arms and legs) even while they are resting. He would look for change of skin color on the feet and hands and check the blood pressure on the limbs. In this procedure a thin long plastic tube is inserted into the groin and dye is injected into it.
Usually the doctor starts with low dosage of aspirin and subsequently may increase the power according to the extent of peripheral vascular disease. A balloon in deflated condition is sent through it and inflated inside the artery for widening the gap to facilitate normal blood flow.


Bypass surgery is one in which the surgeon will bypass the route that supplies blood to the heart and create graft for facilitating good blood flow. He should not eat fat rich diet and stick on to diet that helps in lowering the blood cholesterol. Myoglobin is important as a dynamic O2 store in muscle cells, although myoglobin is not totally saturated with O2. Due to arterial abnormalities and diabetic neuropathy and delayed wound healing, infection or gangrene of the foot is relatively common.
This presence, to some extent, is more than half of the patients with diabetes older than 60 years old. These lead to cold feet which ultimately result into the loss of skin integrity, providing a vulnerable site for infection [2]. Excessive plantar pressure is related to limited joint mobility and to foot deformities (Charcot foot, hammer toe). The bacteria belonging to the group of staphylococcus would cause cellulitis infection and it usually attacks the person when there is development of crack or cut in the skin. For some persons, there may be chills, fatigue, confusion, illness and muscle pain may be accompanied in the symptoms.
In rare case, hospitalization is required if the infection does not subside and you have weakened immunity. These bacteria are able to enter the skin through small cracks (fissures), causing the sudden appearance of redness, swelling, and warmth in the skin. The involved area may rapidly become deeper red, swollen, warm, and tender and increase in size as the infection spreads.
While you are waiting for the appointment with your physician, you can elevate the involved body part in order to decrease swelling. In addition to prescribing antibiotics, your doctor will likely want to make sure that your underlying medical problems, if any, are being adequately managed. The major artery that supplies blood to vital organs like heart, brain, arms or legs can get either partially or completely blocked due to atherosclerosis. This occurs due to conditions like prolonged diabetes, high cholesterol, hypertension, infectious diseases like lupus and old age.
This condition is somewhat serious causing sharp pain on the feet and hands and often pain is felt during night when the person is at complete rest. He may order for ultrasound scan of legs or arms to check for the collection of plaque particles or fatty deposits on the artery. The surgeon would monitor the path of the dye which gives the right picture of problematic areas of artery.
The methods of treatment include medications combined with exercises, angioplasty or surgery.
People with lesions inside the artery or blood vessel with number of constrictions in the artery can be corrected by surgical procedure. The clinical manifestations are divided into the three types of sensory, motor and autonomic neuropathy. The vascular changes which are responsible for foot problems include stiff arteries due to calcification of the smooth muscle cells in the arterial wall (mediasclerosis).
Limited joint mobility and abnormal foot biomechanisms have been associated with an increased risk of ulceration. Usage of corticosteroid drugs for long time would suppress the immunity of the person leading to infection. Cellulitis is sometimes accompanied by fever, chills, and general fatigue.If the infection is left untreated for too long, cellulitis can result in pockets of pus (abscesses) or the spread of bacteria into the bloodstream (bacteremia).


In addition to identifying the type of bacterium that is causing the cellulitis, the laboratory usually performs antibiotic sensitivity testing in order to determine the antibiotics that will be most effective in treating the bacteria.While waiting for the results from the bacterial culture, your doctor may want to start you on an antibiotic to fight the most common bacteria that cause cellulitis. The blood vessel becomes narrow and constricted due to plaque like fatty deposits thereby blocking the oxygenated blood supply to vital organs. Smoking or prolonged use of tobacco or stressful lifestyle can cause damage to the blood vessels causing PVD.
For some people the pain becomes intolerable that they have to stop walking or doing exercise.
Medications of anti-clotting drugs like statins are prescribed to prevent blood clotting on the extremities. Smoking can definitely increase the chance of getting heart attack or stroke and hence quitting smoking is the only way to prevent it. Motor neuropathy causes wasting of small muscles of the feet with hammer toes and weakness of hands and feet.
It could also be the result of poor vision and sensory neuropathy so that the patients does not feel the pain, nor do they see the ulcer. Sometimes he may ask you to do blood culture test and culture of pussy liquid from the affected part.
Blisters or pus-filled bumps may also be present.Cellulitis may be accompanied by swollen lymph nodes, fever, chills, and fatigue. This class of antibiotics has been the cornerstone of antibiotic therapy for staph and skin infections for decades.
Once the final culture results have returned, your physician may change the antibiotic you are taking, especially if the infection is not improving.Mild cases of cellulitis in a healthy person can be treated with oral antibiotic pills. Peripheral vascular disease can be caused by diabetes, high cholesterol, high blood pressure and obesity.
In other words the pain is felt in the form of severe cramps on the legs or arms and the pain becomes worse while doing exercises. For restoring the normal blood flow on the legs and arms drugs like cilostazol or Trental are given.
For individuals with high blood pressure and high cholesterol statin medications are prescribed. The resting ABI is the ratio of the blood pressure in the lower legs to the blood pressure in the arms. CA-MRSA previously infected only small segments of the population, such as health care workers and persons using injection drugs. The ABI is calculated by dividing the systolic blood pressure at the ankle by the systolic blood pressures in the arm. In rare cases peripheral vascular disease can cause ulcers and gangrene and death of the cells on the arms and legs requiring amputation.
It is a non-invasive method to assess the lower extremity arterial system and to detect the presence of arterial occlusion disease.
While CA-MRSA bacteria are resistant to penicillin and penicillin-related antibiotics, most CA-MRSA infections can easily be treated with commonly available nonpenicillin antibiotics.
Rarely, CA-MRSA can cause a deeper skin infection, which usually requires intravenous (IV) antibiotics to treat the infection. There is an additional strain of MRSA (hospital-acquired MRSA), usually found in health care settings, that is susceptible only to intravenous antibiotics, so admission to the hospital is often needed for effective treatment.
