In-flight emergencies: Not as common as you think

Medical emergencies can occur at any time and that means, even while you’re on vacation or flying to your destination. But don’t be alarmed; you may be surprised as to how rare they are. A recent study published in the New England Journal of Medicine investigated the outcomes of medical emergencies on commercial flights between 2008 and 2010.   They found that for every 1 million passengers, 16 emergencies occurred – in other words, one emergency for every 600 flights.   The most common emergencies included fainting at 37.4 percent, respiratory symptoms at 12.1 percent and nausea or vomiting at 9.5 percent.  Interestingly, cardiovascular events like cardiac arrest, and obstetric or gynecological issues each accounted for less than or equal to 0.5 percent.   The Federal Aviation Administration (FAA) mandates that all aircraft carry an emergency medical kit.  These kits are required to have, among other things, aspirin tablets, nitroglycerine tablets, saline solution and epinephrine. These kits are designed to provide flight crew or on-board medical professionals with resources to treat ill passengers, after consulting a ground-based physician in a medical communication center.   According to the report, flights had to be diverted and land at a different destination in only 7.3 percent of the cases.  Often, the reason flights were able to continue to the original destination is because of the training of the flight crew, the supplies in mandatory medical kits and the presence of medical professionals on board.   Oxygen was the most commonly used treatment almost 50 percent of the time, followed by saline solution at 5.2 percent and aspirin at 5 percent. This study does a nice job quantifying the incidence of in-flight medical emergencies and the resulting treatments and providers.   Keep in mind that such medical emergencies are rare, but do occur daily given the vast amount of airline travel across the world.   Rest assured that traveling physicians and other medical professionals are often on board and able to help ill passengers; at minimum, the flight crew will have contact with a physician at an academic medical communication center to remotely aid in treatment.  Dr. David B.

SurvivorLink: Online tool helps child cancer survivors maintain healthy lives

Ansley Riedel was just 10 months old when she was diagnosed with acute myeloid leukemia (AML) – a cancer of the blood and bone marrow. She immediately began radiation and chemotherapy, undergoing treatment up until she was a little older than 3-and-a-half years old.  Then, after receiving a second bone marrow transplant from her 4-month-old baby brother in July of 1991, Riedel reached the goal that every cancer patient hopes to achieve: Remission. “We celebrate what we call my second birthday,” Riedel told FoxNews.com, regarding the special occasion. Nearly 21 years later, Riedel is doing better than ever – but she hasn’t forgotten her time spent in the hospital so many years ago.  Though she was only a toddler at the time, her bout with cancer ultimately inspired her to become a nurse in order to help others like herself. “I remember a lot of the clinic visits – the routine of going to the clinic, getting labs, some of my hospital stays,” Riedel said. “I remember my nurses a lot, which is why I chose to become a nurse.  They were really like my first group of friends that I got to know really well.” While Riedel was ultimately able to turn her cancer into a source of inspiration, post-cancer life has still had its fair share of difficulties. The radiation treatment Riedel underwent at such a young age has had a lasting impact on her health. Between the ages of 10 and 14, Riedel had to receive daily shots of growth hormone because her development had been stunted by treatment.  She also takes a daily medication for low thyroid function – something her doctors speculate may have been affected by radiation. “There’s a lot of unknown because I was so young,” Riedel said. “I have to be pretty careful with my teeth.  The radiation kind of damaged my permanent teeth, so I’m more susceptible to cavities.  I see more of a specialist for my regular cleanings. My roots were damaged and I couldn’t have braces because of that.” The health setbacks Riedel has had to face are not uncommon for cancer survivors.  While radiation and chemotherapy are meant to kill fast-growing cancer cells, they can also damage healthy cells in the heart, kidneys, lungs and more in the process. “Obvious problems cancer survivors have are endocrine (issues), growth hormone deficiency, low thyroid, problems beginning puberty and fertility,” Dr. Lillian Meacham, a pediatric endocrinologist and director of the Cancer Survivor Program at the Aflac Cancer Center in Atlanta, told FoxNews.com.  “They can have…problems related to scarring of the lungs or damage to the heart muscle.  We have to be vigilant about almost every organ to be sure that we are looking out for these problems, mainly because we want to preserve quality of life and decrease health care costs.” For children diagnosed in the 1960s with acute lymphoblastic leukemia, which is the most common form of childhood cancer, the chance of survival was only 10 percent. Fortunately, chances of survival have increased to 80 percent today. Therefore, finding ways to help cancer survivors maintain a healthy lifestyle post-cancer is an ever increasing necessity. To address this need, Meachem and others at the Aflac Cancer Center have created SurvivorLink, an online tool that aims to improve cancer survivors’ quality of life.  According to its website, SurvivorLink hopes to increase awareness about the long-term health needs of child cancer survivors, as well as create a patient portal, which will provide patients with easy access to all their relevant health information. “When kids come to the survivor clinic, we give them a Survivor Health Care Plan – which details what they need throughout their lives to stay healthy,” Meachem said. “They can upload that into this website, so let’s say they move to North Carolina or Montana, they can share their documents to new health care providers.  It’s like having an electronic chart they carry with them at all times.” Riedel is currently in the process of filling out her patient profile on SurvivorLink, and she said she likes how it is specifically tailored to her own personal needs. “One of the good things about SurvivorLink is it’s based on your diagnosis and based on your protocol.  Depending on how much chemo you had, it will tell you specifically that for this one chemo, these are the big side effects and long term things that can result.” As someone who is still actively involved in health care, Riedel is very passionate about increasing knowledge and communication among cancer survivors and their health care providers.  For her, easy access to information is essential for a long and healthy life. “The main message is just to get informed and get help if you need to – but really be an advocate for yourself,” Riedel said. “If you take care of yourself, then other people are going to be more willing to work with you.” Click for more on SurvivorLink.source : http://www.foxnews.com/health/2013/06/05/survivorlink-online-tool-helps-child-cancer-survivors-maintain-healthy-life/

Potential new way to suppress tumor growth discovered

Writing in this week’s online Early Edition of the Proceedings of the National Academy of Sciences (PNAS), Willis X. Li, PhD, a professor in the Department of Medicine at UC San Diego, reports that a particular form of a signaling protein called STAT5A stabilizes the formation of heterochromatin (a form of chromosomal DNA), which in turn suppresses the ability of cancer cells to issue instructions to multiply and grow. Specifically, Li and colleagues found that the unphosphorylated form of STAT promotes and stabilizes heterochromatin, which keeps DNA tightly packaged and inaccessible to transcription factors. …

First non-surgical circumcision device could slow spread of AIDS in Africa, officials say

Health officials have approved a first-of-its-kind, non-surgical circumcision device hailed as a potential game-changer in the battle to forestall the spread of AIDS in Africa. The PrePex is the only circumcision method, aside from conventional surgery, to gain World Health Organization approval to date, according to The New York Times. The international health organization reportedly gave its approval to the device on Friday.    Dr. Eric P. Goosby, the U.S. Global AIDS Coordinator, subsequently told the paper the PrePex would “truly help save lives” and that he was even considering the immediate employment of funds from the President’s Emergency Plan for AIDS Relief to pay for its widespread use in AIDS-ravaged Africa. Circumcision reportedly lowers the chance of a heterosexual male contracting HIV, or the virus that causes AIDS, through sexual intercourse by about 60 percent.  The Times reports the U.S. has thus-far paid for more than 2 million circumcisions in Africa to assist the continent with its spiraling AIDS epidemic. A two-nurse team reportedly employs the PrePex to kill off a male’s foreskin through the utilization of a rubber band. The procedure, The Times reported, necessitates only topical anesthesia, and is safer than surgery. The device was developed by Circ MedTech, an Irsaeli company founded in 2009, according to Bloomberg Businessweek.  source : http://www.foxnews.com/health/2013/06/02/first-non-surgical-circumcision-device-could-slow-spread-aids-in-africa/

New therapy shown to improve progression-free survival and shrink tumors in rare cancer for the first time

The findings are potentially practice-changing for a historically "untreatable disease." Though uveal melanoma is rare — there are only 2,500 cases diagnosed in the United States each year — about half of patients will develop metastatic disease, and survival for patients with advanced disease has held steady at nine months to a year for decades. Researchers found that progression-free survival (PFS) in patients receiving selumetinib was nearly 16 weeks and 50 percent of these patients experienced tumor shrinkage, with 15 percent achieving major shrinkage. Patients receiving temozolomide, the current standard chemotherapy, had seven weeks of PFS and no tumor shrinkage. …
