Surgeons reconstruct baby’s skull with 3D printing technology By Loren Grush

Surgeons reconstruct baby’s skull with 3D printing technology By Loren Grush Published February 21, 2014 FoxNews.com When baby Gabriel was born in August, his dad, Manuel Dela Cruz, said everything initially seemed fine with his new son. It wasn’t until a week after his birth that Gabriel’s parents thought their son’s forehead looked abnormal. “We noticed something was wrong with him,” Dela Cruz, of East Quogue, N.Y., told FoxNews.com. “His eye wasn’t the same, and his right forehead was more protruded than the other one.” Worried for their son’s health, the new parents took Gabriel to a pediatrician, who diagnosed the newborn with unilateral coronal synostosis – also known as anterior plagiocephaly. For babies with this condition, a growth plate fuses prematurely on one side of the skull, causing the forehead to become more and more distorted and form asymmetrically. Although the side effects of plagiocephaly are mostly cosmetic, the deformity can grow significantly worse if left untreated – leading many parents to opt for reconstructive surgery. Knowing what needed to be done, Dela Cruz said it was frightening to have their son undergo an operation at such a young age. “You obviously fear the worse, especially because it was in the head,” Dela Cruz said. “Knowing he was going to be opened up…it was very scary on the part of the parent.” In order to treat Gabriel, physicians at Stony Brook University decided to try a completely new kind of operation – one that would cut down on the time the infant spent in the operating room. Through a collaboration with Medical Modeling Inc. in Golden, Colo., Dr. Michael Egnor and Dr. Elliot Duboys were able to virtually plan the entire surgery beforehand. Additionally, the company created 3D printed before-and-after models of Gabriel’s skull for the surgeons, so they could accurately predict how the operation’s results would look. “The first thing we do, after we make a diagnosis, is a CT scan of the baby’s head… and we sent the CT image to [Medical Modeling],” Egnor, director of pediatric neurosurgery at Stony Brook Children’s Hospital, told FoxNews.com. “Using a computer program, they simulated the baby’s skull with the symmetry and dimensions it should have. Then the company manufactured these templates and sent them to us, so we had the exact measurements.” Knowing exactly how the skull should look after the procedure, 6-month-old Gabriel was brought in for surgery and placed him under anesthesia. In order to get to the deformed bone, the surgeons made an incision across the top of Gabriel’s forehead, exposing the entire front of the skull and eye sockets. Through the use of a special saw, the surgeons removed four pieces of deformed bone and made special cuts in the skull to help reshape and restructure the baby’s head. In an attempt to make the remodeling more precise, Egnor and Duboys utilized the 3D printed templates provided by Medical Modeling, which helped to highlight where the surgeons needed to make their incisions. “They sent us cutting templates, which were pieces of 3D modeling that we were able to place on the child’s skull during surgery,” Duboys, associate professor of surgery at Stony Brook Medicine, told FoxNews.com. “And then we just traced where the cuts should be on the skull, almost like a stencil… And then we know where to cut.” Both Egnor and Duboys said the 3D modeling technology helped to cut down on the length of the procedure, which meant Gabriel spent far less time under anesthesia than during traditional surgery. They hope more surgeons will utilize this 3D imaging and modeling to perform reconstructive surgeries in the future. “I think it’s going to become, over time, acknowledged as the best way to do procedures of this nature,” Egnor said. “I was hopeful that this would work nicely, and it made a believer out of me.” As for Gabriel, Dela Cruz said his son will still need to wear a helmet to reshape his forehead. But overall, he responded extremely well to the surgery and his forehead is not as protruded as it once was. “There are no side effects, and he’s a normal baby,” Dela Cruz said. “…Gabriel responded very good to the procedure, and three or four days after, he was joking and playing. It was great seeing him that way.”

Common Home Contaminants

There are many common products found in homes that have HUGE environmental footprints. While you probably avoid toxins in your cleaning supplies or have ditched plastic water bottles, there are still hundreds of things in your home that could be harming the environment. According to the Silent Spring Institute, levels of toxic chemicals are between 200 and 500 higher indoors than out. Yikes! So who invited all of these harmful pollutants into your house? Chances are they steaked in on any number of common household items. In an effort to make our homes healthy for our families and for the environment, there are a few items you should look out for when decorating your home. While you see the effects of poor indoor air quality through more colds and stuffy noses, there are other hidden environmental impacts associated with household products. Check out this list for a few products you should look out for when shopping for your own home (or redecorating your current one). A smart house starts with a smart homeowner! 1. Flooring The problem In October 2013, a report from the Environmental Investigation Agency found that the U.S. flooring giant, Lumber Liquidators, had purchased illegally logged wood. The high demand for flooring products across the world has long fueled corrupt logging practices that contribute to mass deforestation. In the Russian Far East, illegal logging has caused large-scale deforestation, associated with increased carbon emissions and the destruction of critically endangered tiger habitats. According to the Environmental Investigation Agency’s report, Lumber Liquidators is one among many companies across the U.S, the European Union, Japan, and China that supports illegal timber exports. Nearly 80 percent of all timber exported our of the Russian Far East is done so illegally. Fortunately, there are strict legal guidelines in the U.S. to prevent the trade and sale of illegally sourced wood. In the U.S, for example, the Sustainable Forestry Initiative works to promote legal and sustainable forest management across the world. The World Wildlife Fund has also created the Global Forest and Trade Network (GFTN) which links companies with environmentally responsible forest products. GFTN works to responsibly manage forests used for wood and paper products What you can do Buy flooring that is certified by the Sustainable Forestry Initiative. You can find a list of certified companies on the SFI website. Avoid tropical woods like”Brazilian Walnut” or ”African Teak” when shopping for flooring. Look for reclaimed wood, bamboo, or cork flooring. 2. Furniture The problem Ever noticed the chemical/plastic smell new couches and chairs have? That distinct smell is actually the off gassing of thousands of chemicals that were used to product that piece of furniture. Among the chemicals being released into your indoor air are VOCs, formaldehyde and other carcinogens. These pollutants can seep into your air for weeks and remain in indoor air for longer depending on how effective your ventilation system is. Paints, wood stains, and furniture glues have been known to contain off gassing carcinogens that can cause respiratory irritation, headaches, and even cancer. These chemicals are especially dangerous to children and pets who have a lower tolerance. When VOCs off gas into the atmosphere they contribute to smog production. Like flooring, some furniture is made with illegally logged wood. This not only contributes to deforestation, but also increased carbon emissions as illegally harvested lumber is shipped long distances to reach U.S. markets. What you can do Look for furniture made from recycled metal or plastic instead of wood. These materials require less processing to convert into new pieces and help save old furniture from the landfill. Go for reclaimed wood furniture that is finished with non-toxic wood stains and varnishes. Shop for furniture in vintage stores or flea markets instead of buying new. Always consider the future of the furniture you buy: can these materials be recycled?

Electronics The problem Cell phones and computers can have very large environmental footprints. According to the EPA in 2007, up to 1.8 billion tons of electronics were disposed in landfills, only 18 percent were recycled. This is really hard to hear if you are like me and spend 90 percent of your time staring at a screen of some sort. This is not to say you should go off the grid but you might want to reconsider upgrading to the latest phone/laptop/tablet just for the sake of having the newest gadget. Electronics are made from many non-renewable resources like the oils used to make plastic and heavy metals for wiring and circuitry. There are finite supplies of the metals used to make computers and other electronics and global demands contribute to material scarcity. The environmental impact of mining these metals also create social issues. According to RISI, in the Democratic Republic of Congo, the profits from mining coltan (a metal used in computers) have been used to finance civil war. Screens, hard drives, and plastic casings are usually made by different companies, meaning various components need to be shipped across the world to assemble a single device. RISI estimates that amount of fossil fuels used to produce a computer screen is about 10 times its weight. What you can do First you should try and hold on to your old devices for as long as possible! Opt to replace broken parts rather than getting a whole new device. Or buy refurbished electronics. But if you must upgrade…recycle, recycle, recycle! Chemicals such as mercury, lead and nickel can leak out of electronics sitting in landfills causing more environmental damage. By recycling one million laptops, the U.S. could save the same amount of electricity used to power over 3,657 homes a year. Check out the EPA’s website for instructions on how-to “eCycle” your old computers, TVs, and cell phones. 4. Carpet, Curtains, and Upholstery The problem Carpet, curtains and other decorative upholstery are all hiding places for indoor air pollutants and toxins. These household decorations are commonly made from petroleum byproducts and synthetics like nylon, polypropylene and acrylic. While these fabrics are used for their durability, they are filled with VOCs and toxins that can be harmful to your family and pets. The same qualities that make these items last for long periods of time in your home make for even longer lives in landfills. Synthetics do not biodegrade overtime but will continue to leach toxins into the environment for decades. (Not to mention the use of petroleum products for household furnishings adds to our nations dependency on oil.) Upholstery fabrics used on furniture and curtains are often treated with flame retardants that are hazard to human health. According to the NRDC, exposure to flame retardants has been linked to attention problems in young children, male birth defects, infertility and cancer. What you can do Always look for non-toxic carpet. Low and Zero VOC carpets still contain toxic chemicals. All-natural wool carpets and upholstery fabrics are the best option.
