New Discoveries In Child Autism


A new scientific study finds that children who have autism in the U.S usually take one, two or more prescription drugs; however, little proof exists concerning the medications’ efficacy and safety for treatment of neurodevelopmental conditions.

A recent study of nearly 34,000 kids having an autism spectrum disorder found that almost two-thirds were recommended at least one drug. More than one-third of the children in that group were given two drugs, and one kid in seven took three medications.

Dr. Anjali Jain, the study’s leading author and the Falls Church’s managing consultant, asserted that there are several children getting treatment with psychotropic drugs with unfamiliar effects for harms and benefits. She hoped every parent and guardian would consider these drugs with caution.

Children living with autism have impaired social skills and communication, and often show repetitive manners. In the U.S, approximately 1 in 88 kids has undergone diagnosis with the disorder (autism spectrum), which ranges from mild to severe autism.

The study that was recently released online in Pediatrics talked about the usage of psychotropic drugs. These medications for young adults and children with autism include antidepressants, seizure medications, ADHD (attention-deficit or hyperactivity disorder) drugs, antipsychotics, Parkinson’s drugs and lithium. Dr. Jain said that the most commonly prescribed drugs were antipsychotics, ADHD drugs and antidepressants, or their combinations.

Most of these drugs are given for other synchronized disorders like ADHD or depression. According to Dr. Jain, the major problem is in individuals with autism. This is because it can be difficult to differentiate which behavior matches with which disorder.

Dr. Paul Wang who is the senior vice president of an autism advocacy firm agreed with Dr. Jain’s thought. He asserted that it is challenging to diagnose a person in the view of the autism spectrum disorder. This is due to the fact that someone cannot tell if he or she is depressed or anxious.

Wang added that in such cases therefore, it is possible that something completely unrelated is intensifying symptoms. He noted that a number of these children might not have been comprehensively tested for a bodily condition. A person can thus have a kid with an earache who cannot say what is actually happening, and that might manifest as an aggressive or irritable behavior.

Generally, parent training and other behaviorally based treatments are the initial lines of treatment for kids having autism spectrum disorders. However, Dr. Jain noted that since kids with autism are a varied group, it is difficult to develop a therapy that covers each child.

The only drugs accredited by the United States Drug and Food administration for autism spectrum disorders treatment are aripiprazole (Abilify), antipsychotics, risperidone (Risperdal), which are prescribed for treatment of aggression and irritability. Other drugs may be prescribed in what is referred to as an “off-label” treatment.

Medical Device Sales Careers

Medical Sales Rep

There are numerous jobs in medical sales available to those who are interested in careers in medical supply sales, but this doesn’t mean it will be very easy for anyone to find a suitable job and succeed in it.

Those with the right skills, experience, interest, and education can actually be very successful but before considering a career in this area, there are a number of things that one has to know.    There are mainly two different types of medical sales jobs, and the requirements and the salary vary also depending on which direction you take.

The two typical types of medical supply sales are inside sales and outside sales.

Inside sales representatives are required to contact customers by phone and conduct most of their sales presentations while remaining in an office environment. At times, inside sales jobs may require the sales representatives to telecommute or work from the comfort of their homes, provided that the employer agrees to that kind of setup.

On the other hand, outside sales representatives go out into the territory to meet clients face-to-face. They can be referred to as “field agents”. Field agents can travel large territories to conduct sales with prospective clients. Some companies, especially those involved in the sale of big items such as medical devices or hospital equipment can have junior sales representatives pre-qualify clients before allowing the experienced sales agents to go out to conclude the sales in the field.

There are many different medical supply sales jobs, including medical equipment sales, pharmaceutical sales, and medical device sales.  There are also other medical sales jobs involving the sale of a service like billing, marketing, healthcare recruiting, and many others.While some of these jobs might be consultative, others are more transactional in nature. An example of a consultative sales job can be the sale of a DME (Durable Medical Equipment) like an imaging machine. The sales cycle for such multi-million dollar equipment can be long, involving many decision makers.

Medical sales jobs are amongst the most highly compensated jobs you can find and the salary can range from $30,000 to $200,000 per year. In most cases, outside sales jobs, involving durable medical equipment are the most highly compensated jobs. Pharmaceutical sales will receive a salary around the middle of the wide range, and the lowest salary will be for inside sales jobs involving quick purchases. It is important to note that compensation for medical supply sales jobs will depend on a number of factors, including experience, educational qualifications, the type of product being sold and its price, and the pay structure (salary only, salary with commissions, or commissions only).

The educational requirements may also vary from one medical supply sales job to another. Some companies will require their sales agents to have a degree in a science, especially if their job will involve consultation with C-Level executives and handling complex devices. Acquiring a degree in any medical field will be a plus for those who want to develop a good career in medical supply sales.

In summary, if there are a lot of different ways that one can pursue a career in medical sales.   The choice is up to you and the rewards can be amazing, but you must have the right education, knowledge and drive to succeed.   For more information on actual job listings, the following is a good resource:

Wearable Tooth Sensor Technology for Medical Monitoring

Tooth Sensor TechnologyWhether talking, breathing, smoking, eating, drinking or coughing, our mouths are usually in use. Since the mouth is a cavity that yields medical information for the body, a group from Taiwan National University invented the tooth sensor, a new medical technology, which embeds within one tooth. The tooth sensor is very small that it is able to either straddle a real tooth or fit in an artificial one.

With an accelerometer meant to monitor different actions of the mouth, the group used minute wires within the tooth sensor to carry information to a computer. However, they claim that future sensor models will execute wireless reporting of data using Bluetooth.

The team presented their equipment in Switzerland at the ISWC (International Symposium on Wearable Computers) in early September. Motivation for inventing the equipment, say the scientists, was due to the fact that several oral activities produce an exceptional teeth motion. They say that since the tooth sensor can measure the movement of jaws, it is able to build “classifiers” which classify different mouth activities.

To test the precision of the tooth sensor, the group had eight volunteers put on the sensor whilst performing various mouth activities like talking, chewing gum and coughing. During this process, the computer was building a personal profile and analyzing the data for their oral action.

The volunteers were then asked to repeat the actions while the tooth sensor differentiated each one from the other. The group collected a total of 480 activity tests from the participants. The researchers assert that the sensor was 93.8 percent accurate in detecting oral activity while it was using “person-dependent classifiers,” which are the profiles produced for each specific person.

Even though the accuracy reduced to 59.8 percent when the sensory used “person-independent classifiers” (implying the system did not use tailor-made profiles for every individual), the researchers assert that this could be because of differences in the way people do oral activities.

For instance, they say that a number of people talk or chew slower, faster, softer or harder. They claim is possible to develop this accuracy by broadening the training set to involve diverse oral activity types and sensor placements.

Tooth sensor for Medical Monitoring

The group says the data collected with the sensor can be very useful to doctors, dentists and several other scientists. This is because the equipment offers information on eating, drinking levels and teeth grinding, and it can also measure the levels of stress.

Since the tooth sensor is put inside the oral cavity, the researchers claim the safety is certainly very essential. They say all electronic pieces must be sealed and in case swallowed, the tooth sensor passes through the body with no harm caused. They also note that its safety needs resemble those of the capsule endoscopy where patients swallow camera pills.

The current focus of the team is continuing task to improve the tooth sensor. They are expecting a wireless tooth sensor which will fit within a normal crown.

The Deep Evolutionary Roots of Cancer

cancer_cellsA recent study at Arizona State University has uncovered the latest medical theory on cancer that exposes the deep evolutionary roots of the disease.   The proposal was made by Paul Davies in partnership with Charles Lineweaver from Arizona State University and Australian National University respectively. If their medical theory is right, it promises to adjust the cancer therapy approach and connect the genesis of life to the genesis of cancer and address the disease in the early stages of embryonic development.

Paul and Charles are both hypothetical cosmologists and physicists with vast experience in the discipline of astrobiology. Both turned to cancer study just recently, partly due to the creation of the Hub for the Convergence of Cancer Biology and Physical Science. The Center is among the 12 set up by the National Institute of Cancer to hearten physical scientists to offer their insights into handling cancer.

The new medical theory challenges the traditional belief that cancer develops fresh in every host by a cycle of chance mutational catastrophes. Paul and Charles assert that cancer is basically a systematic and organized response to some kind of physical challenge or stress. They say that it may be caused by a casual accident, but later it predictably unfolds.

Their analysis of cancer is summarized in “Exposing deep evolutionary roots of cancer,” an article written by Paul. The editorial appears in a particular July copy of Physics World dedicated to the chemistry of cancer.

Paul Davies, a Regents Professor from the University of Arizona State, asserts that they visualize cancer as the implementation of an old program pre-loaded within the genomes of every cell. He says that it is fairly like Windows, after suffering errors of some kind, it defaults to safe mode.   As such, Paul depicts the disease as a throwback to an inherited or ancestral phenotype.

The most recent theory foretells that cancer progressively develops through malignant stages; it expresses genes which are more deeply preserved among multicellular creatures, and therefore are more ancient. Paul and Charles are presently examining the prediction by comparing cancer biopsies from gene expression data with phylogenetic trees dating back about 1.6 billion year. They are doing this with the assistance of Luis Cisneros who is a postdoctoral researcher.

Evolution has not eliminated the ancient subroutine of cancer since it totally fulfills essential functions in the early periods of embryo development. Paul explains that the genes which are usually dormant and effective in the embryo are later found to be turned back on into cancer. These genes are also the ancient ones present deep in trees of multicellular life.

While this new theory is promising, the pair still have a lot of work to do to turn theory into the practice of saving lives.
