Aortic Regurgitation Causes Posted By : Dr. D.S. Merchant

Filed under: Medicine — webmaster @ 6:38 am

Causes:

  • Acute Aortic Regurgitation



    o Infective endocarditis may lead to destruction or perforation of the aortic valve leaflet. The vegetation can also interfere with proper coaptation of the valve leaflets and can sometimes lead to frank prolapse or flail of a leaflet.

    o In acute ascending aortic dissection (type A), the retrograde proximal dissection flap undermines the commissural suspensions of the aortic valve leaflets. Varying levels of aortic aortic malcoaptation ad prolapse occur.

    o Prosthetic valve malfunction can lead to AR.

    o Chest trauma may lead to a tear in the ascending aorta and discruption of the aortic valve support apparatus.

  • Chronic Aortic Regurgitation

    o While a congenital bicuspid aortic valve often leads to progressive aortic stensosis., incomplete closure or prolapse can also lead to significant regurgitant flow across the valve. This common congenial lesion remains the most common cause of isolated AR requiring aortic valve surgery. Histologic abnormalities of the bicuspid root frequently lead to proximal aortic dilation and further exacerbation of AR.

    o Connective tissue disorders syndrome, including Marfan syndrome, Ehlers-Danlos syndrome, floppy aortic valve, aortic valve prolapse, sinus of Valslva aneurysm, and aortic annular fistula can all lead to significant chronic AR. The use of diet drugs such as fenfluramine and dexfenfluramine (commonly referred to as Phenfen) may lead to chronic AR, although these data remain controversial at this time.

    o Representative of connective tissue disorders, Marfan syndrome is a common cause of severe AR that requires intervention. This disorder is associated with dilated sinuses of Valsalva, progressing to aortic dilation and AR. These patients are also at very high risk for aortic dissection, depending on the size of the ascending aortic.

    o Rheumatic fever was a common cause of AR in the first half of the 20th century. The cusps become thickened with fibrous tissues and retract, which causes central valvular regurgitation. Most commonly, some fusion of the cusps occurs, resulting in some degree of aortic stenosis and regurgitation. Associated rheumatic mitral valve disease is also very common.

    o Syphilltic aortitis leads to dilatation of the ascending aorta. The aortic annulus becomes dilated, and coaptation of the cusps is lost.

    o Takayasu arteritis involves the aorta and its major branches. AR may complicate type 1 and type 3 of this disease.

    o Ankylosing spondylitis leads to shortening and thickening of the aortic valve cusps and dilatation of the aortic root.

    o Reiter syndrome presents similarly to ankylosing spondylitis. Dilatation of the aortic root and associated AR occurs. Reiter syndrome may involve the coronary ostium rarely, producing angina.

    o Reiter syndrome presents similarly to ankylosing spondylitis. Dilatation of the aortic root and associated AR occurs. Reiter syndrome may involve the coronary ostium rarely, producing angina.

    o Rheumatoid arthritis can produce granulomata involving the valve leaflets and rings. The central portion of the leaflets is usually involved, with sparing of the peripheral portions.

    o Systemic lupus erythematosus (SLE) is associated with Libman Sacks endocarditis, and these verrucous.

  • Electrocardiography findings can reveal of the following, although they are not an accurate predictor of the severity of AR.

    o LV hypertrophy

    o Left axis deviation

    o Left atrial enlargement

    o LV volume overload pattern (prominent Q waves in leads I, aVL, and V3 to V6 and relatively small R waves in V1

    o LV conduction defect (late in disease process)

  • Management Of Chronic Headache Posted By : Alexander Krakovsky -

    Filed under: Medicine — webmaster @ 6:38 am

    Headache is a very common experienced phenomenon. Many headaches are secondary to underlying medical conditions and therefore, the management chronic headache presents significant difficulties to the physician because of the lack of effective therapies.

    Chronic headache affects about 4-5% of adult in the United States. Chronic tension-type headaches (occipital-type headache) and chronic migraine are the most common types of chronic headache. Diagnosis of chronic headache is difficult due to the absence of physical measurements to establish the diagnosis. The overuse of medications to relieve acute headache can cause rebound headache.



    Very important to have precise information about the location of the pain, the quality and intensity of the pain; pain triggers, and associated symptoms before implementing the treatment plan.

    Chronic migraine has following characteristics:

  • Lasting from 4 to 72 hours
  • Unilateral location
  • Pulsating quality
  • Moderate to severe intensity
  • Aggravation by walking stairs or routine physical activities
  • Association with nausea and vomiting
  • Photophobia

    Migraine headache is commonly triggered by diet, menstrual cycle, and exposure to sunlight or prudent odor. Chronic migraine is defined as the occurrence of migraine attacks 15 or more times per month for more than 6 months.

    Chronic tension-type headache has following characteristics:

  • Pain with pressing quality
  • Bilateral, occipital or any other location
  • Mild to moderate intensity
  • Is not aggravated by walking stairs or routine physical activities
  • Associated with nausea but not vomiting

    Tension-type headache is often associated with muscle tenderness in the neck, shoulder, upper arms, the jaw and face and the base of the skull. Chronic tension-type headache must occur more than 15 times per month for more than 6 months.

    Treatment:

    Chronic headache is very difficult to treat. In addition, many of the currently available treatment options lack efficacy. For the treatment of moderate to severe migraine pain, triptans are the treatment of choice. Opioids can also be useful as abortive medications when other therapies fail. In today days Botox injection is available as a treatment for chronic migraine as well. Tension-type (occipital) and cluster headache are usually treated with NSAIDS and muscle relaxant as an initial treatment options. Triptans reserved for the cases when initial treatment does not relive the pain. Botox injection plays a big role in current medical management for the treatment of tension-type headache. For the treatment of occipital headache the first line of treatment is pharmaceutical, and the second line of treatment is steroids and/or Botox injection to relive the muscle spasm damaging occipital nerves. The third line of treatment which is the most effective treatment of occipital headache in today days is peripheral nerve stimulation. Electrical stimulation of the occipital nerves permanently eliminates occipital-type of headache pain.

  • Chronic Pain Treatment In Elderly Patients Posted By : Alexander Krakovsky -

    Filed under: Medicine — webmaster @ 6:38 am

    Elderly patient is the one of the most difficult patient to treat because there are too many additional barriers such as impaired cognition, hearing and vision lost that pain management physician facing during office visit. In addition, many elderly patients do not want to be seen as complainers secondary to their cultural background. Typically, elderly patients have multiple comorbidities such as hypertension, diabetes, chronic obstructive pulmonary disease, chronic heart failure, and chronic renal failure. There are also many psychological comorbities and social problems such as depression, anxiety, ambulation, socialization and vitality as well.

    Physician has to remember that in elderly population pain intensity and drugs pharmacokinetics usually diminished as the patient ages. Drug clearance and drug half-life is altering with renal excreted medications and hepatic metabolized medications. Sensitivity of the drugs to central nervous system is also shifting when the patient aged.



    Chronic pain is tremendously affecting elderly people. It is changing their physical activities; they ability to perform activities of daily leaving; the work and their recreation activities. It is also increasing their psychological morbidity such as depression, anxiety, anger, and loss of self-esteem. Social and societal consequences transform accordingly affecting marital/family reactions; intimacy/sexual activities; increase social isolation; health care cost; disability and lost workdays.

    Neuropathic pain treatment in elderly has several goals such as improving physical functioning; reducing psychological distress, and improves overall quality of life. The first-line pharmacological treatment recommendations for neuropathic pain in elderly would be Gabapentin, Lidocaine patch, Tramadol, Antidepressant and Opioid Analgesics. Second line treatment of chronic pain in elderly patients would be Spinal Cord Stimulator that will allow decreasing all oral medications including opioids. The overall effect would be dramatic changes of the quality of life with an improvement of the physical activities and decreasing all medications’ side affect. The third line of treatment of the chronic pain in elderly population would be an implantation of the intrathecal pump. Intrathecal pump will deliver very small dose of medications into spinal canal and this allows improving the efficacy of these medications and eliminating or decreasing general side effects.

    Lumbar Epidural Injections Posted By : Alexander Krakovsky -

    Filed under: Medicine — webmaster @ 6:38 am

    Many people with chronic back and leg pain require lumbar epidural injections as a medical treatment. This procedure helps relieve low back and leg pain by reducing inflammation, swelling and irritation of the nerves. This injection is also help the doctor diagnose the source of the pain by numbing certain area of the body.

    A lumbar epidural injection won’t stop all low back and leg pain. But it reduces the pain intensity and break the pain cycle. This cycle actually begin when back pain makes it hard to move. On the other hand, the lack of movement slows down the healing process. Some people may feel more pain relief from one injection and some people may need more then one injection to get pain relief. The injection can help locate the source of pain as well. Different injections such as selective nerve block may numb the roots of specific nerves and therefore relief the pain. The effect of this injection very short lasting, but if it relief the pain, it indicates and locates the source of the pain.



    Some people feel more comfortable if they understand their body better before making any decision regarding pain injection procedures.

    Vertebrae are the bones that stack up to from the spine.

    Disks are “cushions” that provide padding between the vertebrae. A damaged disk can lead to inflammation and pain.

    The spinal canal is a tunnel that is formed within the stacked vertebrae. Nerves run through this canal. The nerves are wrapped by a thin layer of tissue.

    A nerve root is the part of nerve that leaves the spinal canal. Inflamed nerve roots can lead to back pain.

    The sciatic nerve is a nerve that extends down to the leg. When its nerve roots are inflamed, buttock and leg pain often result.

    For the pain relief the injection usually has to be performed into epidural space. Epidural space is the area that surrounds the nerves within the spinal canal. To locate the source of the pain the nerve root has to be targeted and the medication has to be injected directly onto that nerve root.

    A lumbar epidural injection is an outpatient medical procedure. In nova days it usually performs in an outpatient surgery center. The actual injection takes just a few minutes but the preparation for the procedure and post injection recovery take a little longer. All patients vital signs controlling by monitoring devices that attached to the patient and measure the heart rate, blood pressure, EKG and the amount of oxygen in the patient’s blood. The injection performs under fluoroscopy (x-ray imaging) that helps to guide the injection.

    After the procedure the patient needs to be careful and not being too active at the same day. Some patients experienced increase the pain sensation at first but in usually goes away within a few days. An injection to reduce inflammation takes a several days to work. Exercises and good body mechanics help keep pain from returning or worsening. The exercises also help build strength and flexibility. Whether epidural injections were for relieving pain or locating pain it is a right treatment choice for low back and leg pain.
