Most of the studies in the medical literature confirm that no major differences exist between brand and generic drugs. However it is fair to recognize that occasional reports have raised concern that certain generic brands may be less effective than brand name products (see: Cervera Barba EJ. [Increase of arterial pressure caused by generic atenolol] Aten Primaria. 2001 Feb 15;27(2):146-8).

The long QT syndrome (LQTS) is causing an abnormality of the heart's electrical system. The mechanical function of the heart is entirely normal. The electrical problem is due to defects in heart muscle cell structures called ion channels. These electrical defects predispose affected persons to a very fast heart rhythm (arrhythmia) called "Torsade de Pointes" (TdP) which leads to sudden loss of consciousness (syncope) and may cause sudden cardiac death.

The diagnosis is commonly suspected or made from the electrocardiogram (ECG). All children and young adults should have an ECG as part of their evaluation for an unexplained loss of consciousness episode. On the other hand, there is the possibility to check blood samples for known gene mutations that cause LQTS.

The name of the long QT syndrome refers to the QT-interval measured on the electrocardiogram (ECG or EKG for the German term "Elektrokardiogramm"). Your specialist may refer to long QT syndrome as Romano-Ward syndrome or Jervell, Lange-Nielsen syndrome (see point 3).

INHERITED: Inherited long QT syndrome was first clearly described in 1957. There are two variants, the autosomal dominant Romano-Ward (named by the doctors who first described the disease, O. Connor Ward and C. Romano) type and the autosomal recessive Jervell, Lange-Nielsen (Doctors A. Jervell, F. Lange-Nielsen) type. Inherited long QT syndrome is caused by mutations of at least 9 genes, and possibly more. Five different genes have so far been found.

The frequency is unknown but it appears to be a common cause of sudden and unexplained death in children and young adults. It is certainly much more common than previously thought. It may be as frequent as 1 in 5000 to 7000. This means, one of 5000 to 7000 newborns have the disease. The Jervell, Lange-Nielsen form is rare, but the Romano-Ward variant is being recognized with increasing frequency. In the USA, the presence of long QT syndrome is estimated to affect about 50.

It is generally estimated that approximately 10% to 12% of all patients with long QT syndrome show a normal QT-interval on their ECG. However, this does not mean that these patients are not affected by long QT syndrome. In such cases, a more profound evaluation is needed.

It has been noticed that several cardiac arrests occur during summer time. But it is not sure if it this may be an excess in statistical terms. It is however hard to define if these cardiac arrests are related to a specific "risk" due to heat or sweating or if it is mainly a reflection of increased physical activity, excitement and playing during the summer.

The 9-month interval during pregnancy and the delivery itself are not associated with an increased occurrence of heart events in any of the LQTS women. However, it appears that the physical and emotional stress during the 9-month period after pregnancy (the postpartum period) may be a factor in triggering heart rhythm disorders in some vulnerable women with LQTS.

There are two ways to make a diagnosis for QT syndrome. The first is to check if the QT-interval on the ECG of a suspected patient is prolonged. Because the heart stopps beating when death occurs, this possbility is out of question - except an ECG of the dead person already exists, of course. The only possibility would be to check body fluids of the dead person - in this case blood - for the known gene mutations that cause QT syndrome.

Studies show there are significant gender differences in genotyped LQTS patients relative to age of first episode, syncope, cardiac arrest and sudden death. Males seem to have a higher risk of cardiac events (meaning syncope or blackout spells, cardiac arrest and sudden death) during childhood (with an average earlier age of onset in males at 8 years old vs.14 years in females), through puberty. Studies reveal females have an increased risk relative to males during adulthood.

Beta blockers are drugs commonly used for heart disease to lower blood pressure and decrease the heart rate. In sports such as shooting or archery, beta blockers might be used to steady the nerves. Abuse of beta blockers can cause heart failure, asthma, depression, sleep disorders and sexual dysfunction.

A backup pump with a dead battery, loose cables, or a clogged pump is like having no backup at all. With other brands, you will never know if there is a problem. All Basement Watchdog backup pump systems have unique monitoring systems that sound an alarm when maintenance is needed, or when a problem arises. All systems also include the fluid sensor that is used to monitor the battery fluid level.

When scientists develop a new drug, they give it a generic name reflecting its chemical makeup. Once the Food and Drug Administration (FDA) approves the drug, the manufacturer markets it with a brand or trade name, which is usually shorter and easier to remember. A drug company can hold exclusive patent rights to make a drug for 20 years after its discovery. After that, other companies can start making generic versions of the drug.

The Nexcare™ Diabetes Skin Care Products do NOT provide any sun protection. Use of a sunscreen product with SPF of 15 or greater is recommended on exposed skin if you plan on being outside for an extended period of time.

Note that Work Units "expire" after a certain amount of time. This means that after a certain amount of time, if the WU has not been returned, we assume it's not coming back and our server moves on from there. This is necessary due to the fact that future work units depend on old ones and so we need to eventually give the work to someone else to get it completed. The times to complete a WU for the PS3 is short (8 hours), so the deadline time is also correspondingly short (2 days).

The duration of the QT-interval is a measure of the time required for depolarization and repolarization to occur. In long QT syndrome, the duration of repolarization is longer than normal. Thus, the QT-interval is prolonged. An interval above 440 milliseconds (msec) is considered prolonged. QT-prolongation in is due to overload of myocardial cells with positively charged ions during ventricular repolarization.

to 470 milliseconds is considered borderline. The average QTc for someone who has long-QT syndrome is 490 milliseconds. A QTc at or above 480 milliseconds in females or 470 milliseconds in males, is probably a sign for long-QT syndrome, in the absence of drugs, electrolyte disturbance, or other conditions that might independently lengthen the QT-interval.

We try to continually carry the same brands of generic drugs, however, sometimes we are at the mercy of our wholesaler. If they do not have the brand that we have been carrying, we may have to use a different brand.

Helmets are tested in the lab for straight line (linear) blows only. Test procedures set by standards bodies like Snell, ANSI, and CPSC require a helmet containing a 5kg (11lbs) rigid headform to be dropped onto a flat anvil from a height of 1.5 to 2.0 metres (5ft to 6ft 8in). If more than 300g's is imparted to the headform the helmet cannot be certified. The outer shell of the 1980's hard shell helmet is designed to spread the force of an impact over a greater area of the head.

No. Sharp, high speed objects are likely to penetrate helmets particularly those with many vent openings. Also, helmet tests monitor the effect of linear force but not rotational force. A blow which is not square on centre, i.e. not linear, will rotate the head. Diffuse injuries - the most serious and common type of brain injuries - result from rotational stresses on the brain. Linear force on the other hand, result in focal or localized injuries rather than diffuse injuries.

Depending upon the amount of prep work that is necessary, typically a protection package including paint sealant, rust proofing, undercoating and fabric and/or leather guard can all be done within one day on a new vehicle. If it is raining or snowing at the end of the day we recommend that the vehicle remain in our shop overnight in order for the undercoating to harden.

Yes, the first ingredient on the label that is listed as "Vitamin A (as natural mixed carotenoids)" is actually beta carotene. The FDA specifications for vitamin labels require the ingredients to be listed by the vitamin's name. Beta carotene is a provitamin to vitamin A and is actually converted by the body into vitamin A. Cooper Complete multivitamin and mineral supplement contains d-alpha tocopherol, the natural form of vitamin E.

Answer. The actual life expectancy of Sylgard is mainly dependant on the insulator design as well as the type of contaminate and the rate of fall out on the insulator surface, however experience shows us that a single application should provide excellent protection for periods in excess of 10 years. The shortest life cycle we have observed is about seven years on a particular design of 345kV bushing in heavy pollution.

The PermaShield process is a combination of decades of experience and a production process that has been scientifically engineered to provide the best protection for granite against staining. PermaShield will provide stain protection for at least 15-years.

According to the American Academy of Family Physicians, the resolution time for plantar fasciitis / heel pain syndrome averages 6-18 months. Roughly half of the reported cases of heel pain caused by plantar fasciitis have had the condition for more than a year.

No. While annual immunization is the most effective way to avoid getting seasonal flu, it will not provide protection from bird flu or any other influenza strain that emerges to create a pandemic. The annual influenza vaccine is only effective against circulating influenza viruses in the human population and includes the influenza strains expected to be in circulation during that year's flu season.

Yes, but not against hydrofluoric acid. The film formed by the products is very hydophobic, water hating, and therefore very effective repelling water-based substances such as mineral acids. It is still highly recommends that these substances be removed as soon as possible. Quick removal helps insure the prevention of any chemical injury from these chemicals.
