What are other therapies for blepharospasm when Botox injections doesn't answer?

First of all, the success of Botox for blepharospasm depends on dosage, placement sites, and skills and/or techniques of the injecting physician. It can take several Botox cycles experimenting with dosage and placement, and sometimes trying out more than one injector, before optimal results are achieved. Botox is dependent upon zinc, so if you have a zinc deficiency, that can negatively affect your results. There is a brand new prescription on the market that you can take a few days before injections to boost your zinc levels. Others have achieved similar results by eating a lot of turkey in the four days prior to injections. There are other brands and strains of botulinum toxin that can be tried, such as Xeomin, Dysport, and Myobloc. Some patients have limited relief with any one of a variety of oral medications, such as clonazepam. When these avenues fail, there are surgical procedures that may be considered, such as limited myectomy or frontalis sling. To learn more about these kinds of therapies, visit the Benign Essential Blepharospasm Research Foundation at blepharospasm.org. There is also a link toward the bottom of that page to a bulletin board where you can communicate with others who suffer from BEB.


Treating Congestive Heart Failure?

If you have been diagnosed with congestive heart failure, treating this can weaken the symptoms related to condition and help your heart function more efficiently as well. Some physicians focus on solving the underlying cause of the problem by opening blocked arteries, controlling a rapid heartbeat, or even replacing or repairing diseased heart valves.Related illnessesAt times, cardiologists also treat various conditions that may cause a patient's congestive heart failure to become worse, including thyroid problems, and anemia. Depending on their condition and prognosis, these are the methods most commonly used in treating congestive heart failure:Surgery may include heart valve replacement or repair, coronary bypass surgery, a heart transplant or myectomy, in which a portion of the septal muscle is removed to decrease the amount of blockage the patient is experiencing.Recommended medical devices in treating this condition include the ventricular assist device (VAD), cardiac pacemaker or internal cardiac defibrillator, which is used to shock the patient's heart into pumping more slowly and beating more effectively.Many medications are used in treating congestive heart failure to relieve patients' symptoms and increase their survival rate. Some are prescribed to prevent blocked arteries and improve circulation, lower blood pressure or prevent the formation of blood clots.HospitalizationAt times, congestive heart failure becomes so severe that the patient most be hospitalized and monitored for a short time. When that happens, they may be given new medication to relieve their symptoms and help their heart pump more efficiently. Supplemental oxygen my also be required as part of their treatment, sometimes indefinitely.Lifestyle changesCertain adjustments can often relieve the patient's symptoms and keep the condition from worsening. The steps they are advised to take include limiting or reducing their consumption of alcohol and caffeine, regular exercise (preferably in cardiac rehabilitation program), eating a low-sodium, low-fat diet, controlling their weight, quitting smoking and keeping stress at a minimum.Patients should also consult with their doctor before taking any medication. For example, common over-the-counter arthritis medicines, including ibuprofen and naproxen, may cause the patient to retain fluid. That, combined with gaining weight, may mean that their heart condition is not being controlled properly.


Hypertrophic cardiomyopathy?

DefinitionHypertrophic cardiomyopathy (HCM) is a condition in which the heart muscle becomes thick. The thickening makes it harder for blood to leave the heart, forcing the heart to work harder to pump blood.Alternative NamesCardiomyopathy - hypertrophic (HCM); IHSS; Idiopathic hypertrophic subaortic stenosis; Asymmetric septal hypertrophy; ASH; HOCM; Hypertrophic obstructive cardiomyopathyCauses, incidence, and risk factorsHypertrophic cardiomyopathy is often asymmetrical, meaning one part of the heart is thicker than the other parts. The condition is usually passed down through families (inherited). It is believed to be a result of several problems (defects) with the genes that control heart muscle growth.Younger people are likely to have a more severe form of hypertrophic cardiomyopathy. However, the condition is seen in people of all ages.SymptomsChest painDizzinessFainting, especially during exerciseHeart failure (in some patients)High blood pressure (hypertension)Light-headedness, especially with or after activity or exerciseSensation of feeling the heart beat (palpitations)Shortness of breathOther symptoms that may occur are:Fatigue, reduced activity toleranceShortness of breath when lying downSome patients have no symptoms. They may not even realize they have the condition until it is found during a routine medical exam.The first symptom of hypertrophic cardiomyopathy among many young patients is sudden collapse and possible death. This is caused by very abnormal heart rhythms (arrhythmias), or from the blockage of blood leaving the heart to the rest of the body.Hypertrophic cardiomyopathy is a major cause of death in young athletes who seem completely healthy but die during heavy exercise. However, certain normal changes in athletes' hearts can confuse the diagnosis.Signs and testsThe health care provider will perform a physical exam and listen to the heart and lungs with a stethoscope. Listening with a stethoscope may reveal abnormal heart sounds or a murmur. These sounds may change with different body positions.The pulse in your arms and neck will also be checked. The doctor may feel an abnormal heartbeat in the chest.Tests used to diagnose heart muscle thickness, problems with blood flow, or leaky heart valves (mitral valve regurgitation) may include:24-hour Holter monitor (heart monitor)Cardiac catheterizationChest x-rayECGEchocardiography (the most common test) with Doppler ultrasoundMRI of the heartTransesophageal echocardiogram (TEE)Not all of these tests are useful for evaluating all of these conditions.Blood tests may be done to rule out other possible diseases.If you are diagnosed with hypertrophic cardiomyopathy, your health care provider may recommend that your close blood relatives (family members) be screened for the condition.TreatmentThe goal of treatment is to control symptoms and prevent complications. Some patients may need to stay in the hospital until the condition is under control (stabilized).If you have symptoms, you may need medication to help the heart contract and relax correctly. Some medications used include beta-blockers and calcium channel blockers, which may reduce chest pain and other symptoms, particularly with exercise. Medications will often relieve symptoms so patients do not need more invasive treatments.Some people with arrhythmias may need anti-arrhythmic medications. If the arrhythmia is due to atrial fibrillation, blood thinners may also be used to reduce the risk of blood clots.Some patients may have a permanent pacemaker placed. However, pacemakers are used less often today than they were in the past.When blood flow out of the heart is severely blocked, an operation called surgical myectomy may be done. This procedure cuts and removes a portion of the thickened part of the heart. Patients who have this procedure often show significant improvement. If the heart's mitral valve is leaking, surgery may be done to repair or replace the valve.In some cases, patients may be given an injection of alcohol into the arteries that feed the thickened part of the heart (alcohol septal ablation), essentially causing a controlled heart attack.An implantable-cardioverter defibrillator (ICD) may be needed to prevent sudden death. ICDs are used in high-risk patients. High risks include:Drop in blood pressure during exerciseFamily history of cardiac arrestHistory of cardiac arrest or ventricular tachycardiaHistory of unexplained faintingLife-threatening heart rhythms on a Holter monitorSevere heart muscle thicknessExpectations (prognosis)Some people with hypertrophic cardiomyopathy may not have symptoms and live a normal lifespan. Others may get worse gradually or rapidly. The condition may develop into a dilated cardiomyopathy in some patients.People with hypertrophic cardiomyopathy are at higher risk for sudden death than the normal population. Sudden death can occur at a young age.Hypertrophic cardiomyopathy is a well-known cause of sudden death in athletes. Almost half of deaths in hypertrophic cardiomyopathy happen during or just after the patient has done some type of physical activity.If you have hypertrophic cardiomyopathy, always follow your doctor's advice concerning exercise and medical appointments. Patients are sometimes advised to avoid strenuous exercise.ComplicationsDilated cardiomyopathyHeart failureLife-threatening heart rhythm problems (arrhythmias)Severe injury from faintingCalling your health care providerCall for an appointment with your health care provider if:You have any symptoms of hypertrophic cardiomyopathyYou develop chest pain, palpitations, faintness, or other new or unexplained symptomsPreventionIf you are diagnosed with hypertrophic cardiomyopathy, your health care provider may recommend that your close blood relatives (family members) be screened for the condition.Some patients with mild forms of hypertrophic cardiomyopathy are only diagnosed by screening echocardiograms because of their known family history.If you have high blood pressure, make sure you take your medication and follow your doctor's recommendations.ReferencesMaron BJ.
