Researchers have developed an artificial retina with the ability to restore normal vision based on its work on deciphering the retina’s neural code for brain communication. It’s the first of its kind – an effective prosthetic retina device that can accommodate for blindness in mice. The results of the project are a major breakthrough in working to restore vision for the blind.

Thyrotoxicosis - Lancet 2012 review

Thyrotoxicosis is a common disorder, especially in women. Thyroid disease affects 7 times more women than men.

Etiology

There are 3 main causes of thyrotoxicosis: Graves' disease, toxic nodular hyperthyroidism, and thyroiditis.

Here are some more details about them:

- Graves' disease (autoimmune hyperthyroidism) is the most frequent cause of thyrotoxicosis
- toxic nodular hyperthyroidism, due to the presence of one or more autonomously functioning thyroid nodules
- thyroiditis caused by inflammation, which results in release of stored hormones

Treatment

The available treatments for thyrotoxicosis have been unchanged for 60 years.

Antithyroid drugs are the usual initial treatment. Thionamides such as carbimazole or its active metabolite methimazole are the drugs of choice.

A prolonged course leads to remission of Graves' hyperthyroidism in only 30% of cases.

Because of this low remission rate in Graves' disease (only 30%) and the inability to cure toxic nodular hyperthyroidism with antithyroid drugs alone, radioiodine is increasingly used as first line therapy. It is the preferred choice for relapsed Graves' hyperthyroidism.

Surgery with total thyroidectomy is an option in selected cases. .

Treatment of Graves' Disease with Antithyroid Drugs in the First Trimester of Pregnancy and the Prevalence of Congenital Malformation »
Background: Several reports have suggested that propylthiouracil (PTU) may be safer than methimazole (MMI) for treating thyrotoxicosis during pregnancy because congenital malformations have been associated with the use of MMI during pregnancy. Objectives: We investigated whether in utero exposure to antithyroid drugs resulted in a higher rate of major malformations than among the infants born to a control group of pregnant women. Methods: We re...

Graves' disease is an eye disorder associated with abnormalities of the thyroid gland. When the immune system attacks the muscles and other ocular tissues in the eye socket, the swelling and scarring resulting from the inflammation causes symptoms and signs like this >>

Swelling (edema) of the eyelids and tissue around the eye
A constant stare
Eyelid retraction
Dry eyes or a sensation of grit or irritation to the eye
Watering and redness of the eyes

BPA: FDA Bans Endocrine-Disrupting Chemical from Baby Bottles and Sippy Cups | Healthland | TIME.com - http://healthland.time.com/2012/07/17/fda-bans-bpa-from-baby-bottles-and-sippy-cups/

The U.S. Food and Drug Administration (FDA) announced that baby bottles and sippy cups can no longer contain bisphenol-A (BPA), the endocrine-disrupting chemical found in plastics and food packaging.

The FDA notes that the ban does not apply to the use of BPA in other plastics or food packaging, including canned food containers, water bottles and baby formula containers.

BPA in Dental Fillings Linked to Behavioral Problems in Children | GreenAnswers -

Dental fillings made out of a bisphenol-A glycidyl methacrylate (bisGMA)-based composite may be inadvertently causing behavioral and psychosocial issues in the children that have them.

BPA Commonly found in the linings of cans, as well as in food and drink containers, BPA has been vehemently protested by those wanting to see it banned from being used in children’s toys and baby bottles. Now, dental researchers fear that significant amounts of the dangerous chemical may be leaching into children’s mouths by way of these fillings.

Antibacterial soap may hinder muscle function: Study -http://www.todayonline.com/Hotnews/EDC120815-0000110/Antibacterial-soap-may-hinder-muscle-function--Study

LONDON - A chemical found in soap, toothpaste, clothes and toys may cause muscle problems and should be used with caution, experts have said.

Triclosan hampers muscle function in animals and fish and may have implications for human health. Further studies are needed to establish the effect triclosan has on human muscles.

Zocor Rhabdomyolysis: An Overview
http://zocorlawsuit-info.com/2012/07/zocor-rhabdomyolysis-overview/
http://zocorlawsuit-info.com/2012/07/zocor-side-effects-led-kidney-failure-claims-plaintiff/

Rhabdomyolysis is a condition in which a patient’s muscles are gradually broken down. The causes may vary, but typically involve some type of trauma or injury. A prolonged coma, genetic muscle diseases, some viruses and bacteria, over-intense exercising, and drug and alcohol intoxication can also lead to the condition.

Zocor rhabdomyolysis differs from standard muscle injury, however, in that it involves the release of proteins into the bloodstream. As the injury or other trauma breaks down the muscle tissues, they may release a protein called “myoglobin” and an enzyme called “creatine kinase” into the blood. The level of these components can be measured by a blood test, which can alert doctors to the presence of rhabdomyolysis, which is also called “muscle wasting.”

Patients with rhabdomyolysis don’t always experience symptoms. Often, however, muscle aches and pain, stiffness, muscle weakness, muscle swelling, and brown or dark-colored urine signal the presence of rhabdomyolysis. These symptoms should be reported to a doctor right away.

In 2011, the FDA issued a warning regarding Zocor, stating that higher 80 mg doses significantly increased the risk for muscle injury, and recommended that physicians stop prescribing the higher amounts to new patients.
