Is tennis with the wheel dangerous? Experts say

Everywhere the children are "sliding" with the famous running shoes. However, many parents are still reluctant about using this accessory that became a fever among the little ones. After all, does sledding offer any risk to the child? "The only danger is if the child falls," says pediatrician Jorge Huberman of the Albert Einstein Hospital.

Orthopaedist Leandro Gregorut of the São Camilo Hospitals Network is not a cause for concern, either. "Because it does not impact the feet or knees, it should not cause any orthopedic problems." Some children often raise their toes to move and this may cause a slight inflammation in the anterior region of the ankle, forcing a tendon called Tibial Anterior. However, this pain tends to improve with the practice and use of tennis, "he says.

Even if the child has some kind of previous problem, such as annoying foot or knee problems, Gregorut says there are no contraindications:" O that is that some children may have more difficulty than others to balance and develop the necessary technique to walk without falling, but with training, patience and without abusing speed, everyone can have a lot of fun, "says Gregorut. > The experts point out that, as the concern must be focused on the tumbles of the small ones, it is essential to invest in safety accessories: "Like every toy that requires balance and it develops speed, such as skateboard, scooter or bicycle, the ideal would be the use of helmets, knee pads and elbow pads. "

The ideal would be for the child to use the shoes for about 40 minutes a day, without leaving to receive other stimuli. "In addition, the child gets bored quickly, ends up using it for a short time: first, because he gets tired of playing, and secondly, because tennis soon stops serving in the foot.It's an interesting accessory because it stimulates the child, understand their laterality and balance, "says Huberman. "We can not say that children can not do anything, it's important to let them have fun," adds the pediatrician.

Assisted Hatching: facilitating the implantation of the embryo

The term "hatching" means in English the moment the embryo implants itself in the womb, by breaking the zona pellucida that surrounds it. Many embryos, however, can not make this break alone and so do not fix and cause miscarriage. The technique was first described in a study published in 1991 and developed throughout the 1990s.
