Fearing rare side effects, many shun osteoporosis drugs

Millions of Americans are missing out on a chance to avoid debilitating fractures from weakened bones, researchers say, because they are terrified of exceedingly rare side effects from drugs that can help them.

Reports of the drugs' causing jawbones to rot and thighbones to snap in two have shaken many osteoporosis patients so much that they say they would rather take their chances with the disease. Use of the most commonly prescribed osteoporosis drugs fell by 50 percent from 2008 to 2012, according to a recent paper, and doctors say the trend is continuing.

Last month, three professional groups — the American Society for Bone and Mineral Research, the National Osteoporosis Foundation and the National Bone Health Alliance — put out an urgent call for doctors to be more aggressive in treating patients at high risk, and for patients to be more aware of the need for treatment. It followed a flurry of recent articles in medical journals documenting and bemoaning patients' abandonment of traditional osteoporosis drugs. But osteoporosis experts are afraid their efforts will do little to change minds.

Editorial: Positive results for HPV vaccine

A recent study proves that a vaccine designed to combat cervical cancer works and has reduced the cancer-causing virus in girls by nearly two-thirds. The study should provide doctors with all of the evidence they need to recommend the vaccine to parents and satisfy the concerns of hesitant parents. There is no excuse for leaving children susceptible to serious disease when a remedy is readily available.

A government study published in Pediatrics compared infection rates for the human papillomavirus in girls and women before the HPV vaccine's debut in 2006 with the rate of infections in the same age group from 2009 to 2012. Researchers found that the four strains of HPV covered by the early vaccine had decreased by 64 percent in girls 14-19, according to the New York Times. Women ages 20-24 saw declines of 34 percent. The rates of HPV in women 25 and older did not decrease.

Beyond condoms, vasectomies: New male birth control options in the works

womanNearly half of all pregnancies in the United States are unplanned. The Centers for Disease Control and Prevention reported that among women 19 and younger, four out of five pregnancies are unintended. In our country, where birth control options are readily available, roughly 62 percent of women of reproductive age use contraception, according to the CDC.

Currently, men have two birth control options: condoms and vasectomies. Condoms can have a success rate of 98 percent, but they often are used incorrectly. Further, a recent survey of high school students found that 41 percent of them did not use a condom the last time they had sex. Vasectomies have been used as a contraceptive since the 19th century. However, for many men, the idea of any cutting or snipping on or around their testicles brings tremendous anxiety and uneasiness.


Finding a male birth control option besides vasectomies and condoms has proved difficult because men are capable of producing an astounding 1,500 sperm cells in a single second. A healthy sperm count can range from 15 million to 200 million sperm in every milliliter of semen, according to the Mayo Clinic. Scientists have been researching male birth control ideas for some time, and it seems several new options may soon be available.

More than 250 men have undergone reverse inhibition of sperm under guidance, or RISUG. Human trials of RISUG, which can provide contraception for up to 10 years, are moving forward in India and have shown promise. During the procedure, a thick substance is injected into a man's vas deferens, the duct that carries sperm from the testicle to the urethra, rendering sperm infertile. Inspired by RISUG, the Parsemus Foundation, a small funder with an interest in the male contraceptive advocacy movement, began working on a reversible and surgery-free birth control option similar to a vasectomy: a jelly called Vasalgel that is injected into the vas deferens to block sperm. As with RISUG, Vasalgel can be dissolved with an injection of a separate solution, making the procedure reversible. Vasalgel may be on the market as soon as 2018.

The Population Council has been working on a male contraceptive option called MENT, a one-year implant that is placed under the skin of a man's upper arm. The implant releases a synthetic steroid resembling testosterone, which affects sperm cell development. The implant suppresses a hormone that stimulates the growth and activity of the testes. The Population Council also is working on topical gels that inhibit sperm production by releasing hormones that reduce sperm production by nearly 90 percent.

In 2001, the National Institutes of Health began exploring a male birth control pill called Gamendazole. The pill allows for normal ejaculation but creates nonfunctional sperm. During clinical trials, the pill caused 100 percent infertility in male rats. The drug's effects are reversible eight to 10 weeks after stopping the pill. In addition to Gamendazole, several other pills also have shown promise.

Therapeutic ultrasounds also have been shown to reduce sperm count. A man's testes need to be slightly cooler than his body temperature to properly produce sperm. When heating the testes to body temperature and above, sperm counts decrease. Therapeutic ultrasounds heat the testes. In studies conducted with rats, two consecutive 15-minute ultrasound treatments drastically reduced the rats' sperm counts, making them infertile. Other studies have been conducted on dogs and monkeys, with no noticeable side effects other than infertility. For reasons still unclear to researchers, therapeutic ultrasounds provide contraceptive effects that are more substantial than heat alone could provide. There does remain some question as to whether fertility returns after therapeutic ultrasound use is discontinued.

Researchers also have been exploring the "clean sheets pill," a hormone-free method of male birth control that eliminates semen emission while still allowing for the feeling of ejaculation. The pill relaxes the muscles in the vas deferens, which are charged with propelling sperm through the ejaculatory ducts, reducing chances of pregnancy and drastically reducing the male-to-partner transmission of HIV.

It is likely you will see one or more of these options on the market by 2018. The time for male birth control is long overdue. Men want, and need, to be charged with reproductive responsibilities. A recent study by the Kaiser Family Foundation found that 66 percent of men were willing to take a birth control pill, 44 percent were interested in a birth control shot and 36 percent were willing to have a birth control implant.

With the world's population skyrocketing and unintended pregnancies soaring, there is a need for more attention to birth control methods.

What you need to know about HPV and Cervical Cancer

HPV or Human papillomavirus is very common, in fact, 8 out of 10 women will have had HPV by the time they’re 50.  Some types of this virus are spread by sexual contact.

More than 100 different types have been indentified. A few types have been linked to cervical cancer.  A few other types cause external genital warts.  Warts often easily treated and are not linked to cancer.
