Skipping shots at sick visits tied to vaccine delays

Kids who don't get vaccines when they see their pediatrician for a sick visit - despite being due for the shots - are more likely to fall behind on immunizations and routine check-ups, according to a new study. “It's pretty common that kids will come in (for a sick visit) at a time when they should be getting their shots,” said Steve Robison, the study's author and a researcher at the Oregon Immunization Program, part of the state's health department. Sometimes babies end up skipping those shots, perhaps because parents are concerned they could make a sick baby feel worse or doctors are worried that parents won't come back for a well-baby check-up if infants are already caught up on vaccines. “The challenge is, if they come in sick, are they going to come back and get shots and well-baby visits in a timely way?” Robison said. His findings suggest those babies end up worse off if doctors forgo shots until they're better. “It's very clear that vaccinating at sick visits improves the vaccination rate,” said Dr. Alexander Fiks, a pediatrician at The Children's Hospital of Philadelphia, who was not part of this study. “For parents, what I would say is, don't be afraid to get vaccines at sick visits because, for most kids with minor illnesses, it's really no problem. Medically, it's fine,” he added. The Centers for Disease Control and Prevention recommends that babies receive at least 16 vaccine doses during their first six months. Those are spread across well-child visits. In an earlier study, Robison and his colleagues found a growing number of parents in Oregon are not sticking to the recommended vaccine schedule - so kids end up getting their shots late or not at all. This time, Robison looked at the immunization records of 1,060 children who went to the doctor for an ear infection around the time when a well-baby check-up should occur. All of the children had state-funded health insurance. About 8 percent of the sick babies received a diphtheria, tetanus and pertussis (DTaP) vaccine at the sick visit itself, and another 57 percent had one within a few weeks. The others were late on their shots. Fiks said the findings support the results of other studies showing that when doctors skip shots at sick visits, kids are more likely to end up not following the immunization schedule. What's more, giving shots at sick visits did not seem to stop parents from bringing their baby back for well-child visits. Compared to babies who received their immunizations at routine check-ups, those who had their shots at sick visits had just as many well-baby visits by age two - about five, on average. And kids who skipped the shot at their sick visit, but had another visit within a few weeks, ended up receiving more routine check-ups compared to similar normally-vaccinated children, Robison reported in the medical journal Pediatrics. On the other hand, kids who didn't get a shot at the sick visit or within four weeks had slightly fewer routine visits over their first two years. Increasingly, children are becoming “under-vaccinated,” researchers said. A study earlier this year found that half of some 300,000 kids born between 2004 and 2008 had fallen behind on their immunizations at some point before age 2. The concern is that those children are vulnerable to the diseases that vaccines are designed to prevent. “The more kids within a given classroom who are unprotected, the more likely it is for there to be an outbreak,” said Fiks. The researchers agreed that a minor illness is not a reason to fall behind on routine shots. “If you want to keep the kids on schedule so that they're protected from disease, it's best to give the shot,” Robison said.source : http://www.foxnews.com/health/2013/06/06/skipping-shots-at-sick-visits-tied-to-vaccine-delays/

Statins linked to muscle pain, sprains

Cholesterol-lowering drugs could be tied to more muscle problems than researchers previously believed, a new study hints. Researchers compared two groups of similar people enrolled in military health insurance and found those taking a statin were about 10 percent more likely to have muscle pain, sprains or strains. Past studies have tied the popular cholesterol drugs to muscle weakness as well as the rare muscle-wasting disease rhabdomyolysis. The new study expands on those findings and suggests the muscle-related side effects of statins might be broader, researchers said. However, they don't prove statins caused the pain and injuries seen among some patients. “I would strongly recommend that no one should stop taking statins based on this study… simply because statins have been life-saving for many patients,” said the study's lead researcher, Dr. Ishak Mansi. However, he said side effects including muscle injuries are something to think about for people who are discussing with their doctor whether they really need to be on a statin. And they're another reason to try to maintain a healthy lifestyle - including exercising and not smoking - to avoid needing drugs in the first place, he added. Mansi, from the VA North Texas Health Care System in Dallas, and his colleagues compared the health records of two groups of patients who were the same age and had the same types of medical conditions. People in one group had been prescribed a statin in late 2004 and 2005; those in the other group never took statins during the study period. The researchers tracked the medical records of each of those patients - about 14,000 in total - through early 2010 for signs of muscle problems. They found 87 percent of statin users had some type of muscle or joint problem - including arthritis and muscle injuries - compared to 85 percent of people who didn't take a statin. Strains, sprains and dislocations, in particular, were reported for 35 percent of people on a statin, compared to 32.5 percent of those not taking a cholesterol-lowering drug. And medical records showed muscle pain among 73.5 percent of statin users, versus 71.5 percent of non-users, Mansi's team reported in JAMA Internal Medicine. Mansi said those proportions are a bit higher than usual both in the statin and non-statin groups - possibly because his study included military members and veterans, who are more likely to get injured. The researchers calculated that 37 people would have to be treated with statins for one more to have a muscle strain or sprain, and 58 people for one more case of muscle or joint pain. About one-quarter of U.S. adults aged 45 and older take statins to protect against heart attacks and strokes. The drugs are especially recommended for people with diabetes or a history of cardiovascular problems. Dr. Paul Thompson, chief of cardiology at Hartford Hospital in Connecticut, said his own research suggests about 5 percent of people will have muscle problems related to statin use. “We think it's a much bigger problem than it's given credit for,” Thompson, who wasn't involved in the new study, said. However, he said, those muscle problems don't seem to be permanent. “I encourage people to not worry about the possibilities of muscle troubles,” he said. “If they get muscle troubles, we'll stop the drug, and it will go away.” Mansi agreed that people “don't need to be excessively worried” about muscle pain or injuries tied to statins, but that they're something to consider. “Patients need to discuss with their doctors the benefit-risk ratio of statins for them specifically,” he said.source : http://www.foxnews.com/health/2013/06/05/statins-linked-to-muscle-pain-sprains/

Obesity surgery-diabetes study shows pros and cons

Obesity surgery worked much better at reducing and even reversing diabetes than medication and lifestyle changes in one of the most rigorous studies of its kind. But the researchers and others warn that possible serious complications need to be considered. The yearlong study indicates that the most common weight-loss surgery, gastric bypass, can effectively treat diabetes in patients with mild to moderate obesity - about 50 to 70 pounds overweight, the researchers reported Tuesday in the Journal of the American Medical Association. Other studies have shown the operation can reverse diabetes in severely obese patients, although sometimes the disease comes back. About a third of the 60 adults who got bypass surgery in the new study developed serious problems within a year of the operation, though some cases were not clearly linked with the surgery. That rate is similar to what's been seen in previous studies. But for the most serious complications - infections, intestinal blockages and bleeding - the rate was 6 percent, slightly higher than in earlier research. The most dangerous complication occurred in one patient when stomach contents leaked from the surgery site, leading to an overwhelming infection, leg amputation and brain injury. Lead author Dr. Sayeed Ikramuddin, an obesity surgeon at the University of Minnesota, called that case “a fluke.” A journal editorial says such devastating complications are rare, but that “the frequency and severity of complications ... is problematic” in the study and that the best way to treat patients with both obesity and diabetes “remains unknown.” A research review in the journal said more long-term evidence on risks and benefits is needed to determine if obesity surgery is an appropriate way to treat diabetes in patients who aren't severely obese - at least 100 pounds overweight. More than 20 million Americans have Type 2 diabetes; most are overweight or obese. Diabetics face increased risks for heart disease and strokes, and poorly controlled diabetes can damage the kidneys, eyes and blood vessels. About 160,000 people nationwide undergo various types of obesity surgery each year. Bypass surgery, the type studied, involves stapling the stomach to create a small pouch and attaching it to a lower part of the intestines. The American Society for Metabolic & Bariatric Surgery says obesity surgery is safe and that the death rate is less than 1 percent, lower than for gallbladder and hip replacement surgery. The study involved 120 patients at five hospitals in New York, Minnesota and Taiwan. All patients got medicines for diabetes, obesity, cholesterol and/or high blood pressure. They all were advised to cut calories and increase physical activity. Sixty patients also had surgery, and the two groups were compared after one year. The surgery group lost on average nearly 60 pounds and 75 percent lowered blood sugar levels to normal or near normal levels. The non-surgery group lost an average 17 pounds and just 30 percent reached the blood-sugar goal. The surgery group also needed less medication after the operation. The researchers say the diabetes changes were likely due to the weight loss but that hormonal changes affecting blood sugar may have contributed. The surgery group showed a trend toward having less high blood pressure and elevated cholesterol - both major risk factors for heart disease, although those between-group differences could have been due to chance. Ikramuddin, the lead author, said the study results don't mean that all mildly obese diabetics should have obesity surgery, but that “in the correct patient, surgery might be an important thing to consider.”source : http://www.foxnews.com/health/2013/06/05/obesity-surgery-diabetes-study-shows-pros-and-cons/

Tests reveal 66-year-old who lived as a man actually is a woman

A 66-year-old who lived his whole life as a man was given a surprising diagnosis after visiting the doctor in Hong Kong with a swollen abdomen - he was a woman. Doctors realized the patient was female after they found the swelling came from a large cyst on an ovary, the Hong Kong Medical Journal reported. The condition was the result of two rare genetic disorders. The subject had Turner syndrome, which affects girls and women and results from a problem with the chromosomes, with characteristics including infertility and short stature. But he also had congenital adrenal hyperplasia, increasing male hormones and making the patient, who had a beard and a “micropenis”, appear like a man. “Were it not due to the huge ovarian cyst, his intriguing medical condition might never have been exposed,” seven doctors from two of the city's hospitals wrote in the study published on Monday. The doctors said there have been only six cases where both genetic disorders have been reported in medical literature. Turner Syndrome on its own affects only one in 2500 to 3000 females.

Genetic signature of deadly brain cancer identified

"This study identifies a core set of genes and pathways that are dysregulated during both the early and late stages of tumor progression," said University of Rochester Medical Center (URMC) neurologist Steven Goldman, M.D., Ph.D., the senior author of the study and co-director of the Center for Translational Neuromedicine. "By virtue of their marked difference from normal cells, these genes appear to comprise a promising set of targets for therapeutic intervention." As its name implies, gliomas arise from a cell type found in the central nervous system called the glial cell. Gliomas progress in severity over time and ultimately become highly invasive tumors known as glioblastomas, which are difficult to treat and almost invariably fatal. …

Mystery behind dormant breast tumor cells that become metastatic unlocked

In a small but significant number of breast cancer patients, cancerous cells can move through the bloodstream from breast tissue to secondary sites in other parts of the body where they may remain in a dormant state, clinically undetected, for an extended period of time, before suddenly becoming metastatic. …

New technology makes breast cancer surgery more precise

Surgeons at UC Irvine Medical Center are the first in the country to use a device that reduces by half the need to reoperate and cut out breast cancer cells missed during an initial lumpectomy. The MarginProbe System lets the surgeon immediately assess whether cancer cells remain on the margins of excised tissue. Currently, patients have to wait days for a pathologist to determine this…

Woman claims she contracted herpes from lipstick at a Rihanna concert

A Harlem woman is claiming she contracted herpes from a sample of RiRi Woo lipstick she tested at a Rihanna concert in Brooklyn on May 7, Medical Daily reported. Starkeema Greenidge, 28, has filed a lawsuit in Manhattan Supreme Court against MAC Cosmetics, which manufactures the product.  According to Greenidge, she visited a pop-up shop at the singer’s Barclay’s Center show, where a Mac Cosmetics representative applied the RiRi Woo lipstick to Greenidge’s lips. Caused by the herpes simplex virus, herpes is a common sexually transmitted disease (STD) that affects 16.2 percent of Americans, or one out of every six people, between the ages of 14 and 49, according to the Centers for Disease Control and Prevention.  The disease is often contracted through sex, but it can also be transmitted through touching and kissing while an infected individual has a herpes “flare up.” Greenidge said in the suit that the MAC Cosmetics representative failed to warn her that the lipstick had been used by other concert attendees.  When Greenidge developed a cold sore two days later, she went to the doctor, where she was diagnosed with herpes. According to the lawsuit, Greenidge has suffered mental anguish and distress after contracting the STD, Medical Daily reported. A spokesperson for MAC Cosmetics issued a statement to the Daily Beast on Thursday about the incident: “Consumer safety is a top priority at MAC Cosmetics, and we take these matters very seriously. We are closely reviewing these claims.” Click for more from Medical Daily.source : http://www.foxnews.com/health/2013/05/31/woman-claims-contracted-herpes-from-lipstick-at-rihanna-concert/
