Laura Geraghty was shocked 21 times before she came back from cardiac arrest with tales of the afterlife.

Caleb Hellerman
CNN Medical Senior Producer

Our special this weekend, “Another Day: Cheating Death,” includes the story of Laura Geraghty, a school bus driver in Massachusetts who survived a cardiac arrest that left her without a heartbeat for 57 minutes. While the medical aspect is astounding, just as interesting is the story Geraghty told when she was revived.

She’d floated out of her body, and found herself in a world of incredibly bright light – heaven, she says. While there she saw her son, daughter, granddaughter and even her ex-husband – who wouldn’t take her hand when she reached out to him. Eventually she came back to the real world.

Many cultures and religions describe a vivid world on the border of life and death, but the classic modern near-death experience, or NDE, was described by Dr. Raymond Moody in his 1966 book, “Life After Life.” While not every NDE includes the same features, among the most common – according to Moody – are bright lights, a tunnel, a sense of being out of the body and an intense feeling of peace and calm.

Most people who return from the verge of death with memories like this say it’s a life-changing experience. Many view it as direct proof of an afterlife – that the place they “visit” is the world we all will see after we die. But increasingly, near-death experience (a term coined by Moody) is being studied from the perspective of science.

Dr. Kevin Nelson, a neurologist at the University of Kentucky, believes an NDE is caused by REM activity, the same type of brain activity that’s linked to dreaming. REM activity, says Nelson, can be triggered by intense stress or even lack of oxygen. In fact, he says many people experience an out-of-body experience during fainting episodes, or if they momentarily lose blood flow to the brain – as in a massive head rush.

Mary Peterson's daughters, 3 and 1, will not be getting the new vaccine, she said.

Mary Peterson of Des Moines, Washington, doesn't believe the vaccine for the novel H1N1 flu has been studied enough to get it for herself and her daughters, who are 1 and 3 years old.

"I wrestled with it," she said. "I think the side of caution in this case is just waiting until we have more information."

Peterson is one of many parents who are discussing - whether in real life or on Twitter - their skepticism of the vaccine. The vaccine is being distributed as an intranasal spray this week, and will arrive next week in injection form, said Dr. Thomas Frieden, director of the Centers for Disease Control and Prevention, earlier this week.

The CDC and other public health authorities say the new vaccine is safe, and are encouraging everyone to get it, especially those in high risk groups. But experts acknowledge that many people struggle with the decision.

"I bet half the people in the country have concerns," Dr. Mehmet Oz, host of the "Dr. Oz Show" and professor of surgery at Columbia University, told CNN's Anderson Cooper earlier this week.

Ever wonder why your physician only spends 5-10 rushed minutes with you during your office visit? You may think it’s because there are simply too many patients vying for her time, but that’s not the real reason. The root cause is that health insurance companies are stealing time from your visit by requiring excessive documentation from your doctor. She can’t give you the time you need, because doing so would put her out of business.

In a special report on the administrative burden of healthcare, MedPage Today revealed that PCPs spend about one third of their income on documentation required by health insurers. Because they run a business with thin margins, they must increase the volume of patients they treat in order to cover the salaries of the staff required to manage this “paper weight.”

About 49% of all physicians have said that they are considering retiring or quitting medicine in the next two years (the rate is lower for specialists), largely because of increasing documentation requirements and decreasing reimbursement.

On a cold morning in February, 10 days after undergoing in vitro fertilization, Carolyn Savage lay in bed at her Ohio home waiting for the results of her pregnancy test.

Time was moving slowly. It was getting late and the call from the fertility clinic should have come by lunchtime.

"We were waiting and waiting and the call seemed like it would never come," Savage said.

Finally, around 4 p.m., Carolyn's husband, Sean, got the call at work.

"The doctor told me in one sentence, 'Carolyn is pregnant, but we transferred the wrong embryos,'" he said. "I didn't even know that could physically happen. It was a total shock, totally beyond the realm of possibility."

In a tragic mix-up, the Savages say the fertility clinic where Carolyn underwent in vitro fertilization implanted another couple's embryos into Carolyn's uterus.

The H1N1 flu virus could cause up to 90,000 U.S. deaths, mainly among children and young adults, if it resurges this fall as expected, according to a report released Monday by a presidential advisory panel.

The H1N1 virus, commonly known as swine flu virus, could infect between 30 percent and 50 percent of the American population during the fall and winter and lead to as many as 1.8 million U.S. hospital admissions, the President's Council of Advisors on Science and Technology reported.

The report says 30,000 to 90,000 deaths are projected as part of a "plausible scenario" involving large outbreaks at schools, inadequate antiviral supplies and the virus peaking before vaccinations have time to be effective.

Do you have questions about these numbers? Let us know! Dr. Sanjay Gupta will be on 360° to answer them tonight.

When President Obama recently cited the number of Americans without health insurance, he declared that, "We are not a nation that accepts nearly 46 million uninsured men, women, and children."

Uninsured patients often delay preventive care, waiting to seek medical attention only when their conditions worsen. This leads to more intensive treatment, often in the emergency department or hospital where costs run the highest.

Universal health coverage is therefore a sensible goal, and the reforms being considered all make considerable effort to provide everyone with affordable health care.

But expanding coverage cannot succeed as long as there remains a shortage of primary care clinicians.

After all, what good is having health insurance if you can't find a doctor to see you?

Digitizing health records. A good idea say most experts, but it will take a feat of policy, technology and education to ensure your records don't get into the wrong hands.

It all starts with one basic question: Who actually owns your health records?

"Right now, hospitals assume the liability, but the model has to shift to one where the patient controls the data and whether it is put online," said Dr. David Brailer, chairman of Health Evolution Partners and former health tech czar under President Bush. "The people who hold your data control your data."

Prescribed opioids - pain medication - have become the fastest-growing addiction problem in the United States. They are second to marijuana as the most commonly used illicit substances.

Vicodin and OxyContin lead the way among our youth; the 2008 "Monitoring the Future Study" by the National Institute on Drug Abuse found that 9.7 percent of high school seniors have misused Vicodin and 4.7 percent OxyContin.

There is a naïve consensus that these are safe medications because they are prescribed by physicians. However, they are extremely reinforcing, highly addictive and in the same class of drugs as heroin.

Sellers of marijuana as a medicine here don't fret about raids any more. They've stopped stressing over where to hide their stash or how to move it unseen.

Now their concerns involve the state Board of Equalization, which collects sales tax and requires a retailer ID number. Or city planning offices, which insist that staircases comply with the Americans With Disabilities Act. Then there is marketing strategy, which can mean paying to be a "featured dispensary" on a Web site for pot smokers.

After years in the shadows, medical marijuana in California is aspiring to crack the commercial mainstream.

"I want to do everything I can to run this as a legitimate business," says Jan Werner, 55 years old, who invested in a pot store in a shopping mall after 36 years as a car salesman.

State voters decreed back in 1996 that Californians had a right to use marijuana for any illness - from cancer to anorexia to any other condition it might help. But supplying "med pot" remained risky. The ballot measure didn't specify who could sell it or how. The state provided few guidelines, leaving local governments to impose a patchwork of restrictions. Above all, because pot possession remained illegal under U.S. law, sellers had to worry about federal raids.

But in February, the Justice Department said it would adhere to President Barack Obama's campaign statement that federal agents no longer would target med-pot dealers who comply with state law. Since then, vendors who had kept a low profile have begun to expand, and entrepreneurs who had avoided cannabis have begun to invest.

The general anesthetic Diprivan (propofol) has been making headlines as questions about Michael Jackson’s death abound. A nurse who had worked for the singer told CNN that Jackson requested the drug because he had trouble sleeping, and The Associated Press reported that it had been found in his home. Diprivan is not approved as a sleep aid by the Food and Drug Administration. Read more about propofol.

It turns out that propofol, used routinely for surgeries and procedures such as colonoscopies, has been a point of concern among some anesthesiologists because of the potential for abuse by health care workers. A 2007 study published by the International Anesthesia Research Society found that about 18 percent of the 126 academic anesthesia programs in the United States had at least one reported instance of propofol abuse within the previous 10 years.

Researchers also found that six out of 16 residents (about 38 percent) who abused propofol died from it. While these are small numbers, lead author Dr. Paul Wischmeyer, professor of anesthesiology at the University of Colorado, believes this is indicative of a larger problem.

Patients undergoing surgery may receive Diprivan to keep them sedated during the procedure.

Elizabeth Landau

Diprivan is a powerful I.V. anesthetic drug used for patients undergoing certain surgeries and diagnostic procedures.

The drug is making headlines with the claim from a nurse who worked for pop icon Michael Jackson that the singer, who died June 25, had repeatedly asked her about the drug. Nurse Cherilyn Lee told CNN that Jackson had brought up Diprivan about three months ago, saying he needed it for insomnia and that his doctor said it was safe.

"He said, 'I am so sleepy. I cannot sleep. I want to have at least eight hours of sleep,'" Lee told CNN's Anderson Cooper.

The medication, whose generic name is propofol, renders the patient unconscious for as long as doctors deem necessary. The patient wakes up almost immediately after the infusion is stopped, experts say.

But treating sleep disorders is not an approved use of the drug. The U.S. Food and Drug Administration says Diprivan should be given only by people trained in the administration of general anesthesia and who are not involved in the conduct of the surgery or diagnostic procedure.

For toxicology screenings, blood samples are drawn from the leg and heart, as drugs can circulate around the body.

Unlike television crime shows in which machines can instantly spit out results, toxicology testing to determine what drugs are in a person's body can be a long and painstaking process.

The Los Angeles County coroner's office estimates that toxicology tests on the body of Michael Jackson could take six to eight weeks. The results are needed to determine the singer's cause of death, a spokesman for the coroner said. The singer's autopsy last week was inconclusive, although officials said there were no indications of external trauma or foul play.

Identifying drugs in the human body requires a lengthy sequence of tests and confirmations that can take weeks and even months, forensic experts said.

Questions about the possible role of prescription medications in Jackson's death have swirled since Thursday, when the singer was found unconscious. Edward Chernoff, attorney for Dr. Conrad Murray, who tried to revive Jackson at the singer's rented home, said the doctor was not aware of any prescription drug abuse by Jackson.

Anal cancer is fairly rare - much less common than cancer of the colon or rectum. The American Cancer Society estimates that in 2009 about 5,290 new cases of anal cancer will be diagnosed in the United States. The number of new anal cancer cases has been on the rise for many years.

Lifetime Risk
Based on rates from 2004-2006, 0.16% of men and women born today will be diagnosed with cancer of the anus, anal canal, and anorectum at some time during their lifetime. This number can also be expressed as 1 in 624 men and women will be diagnosed with cancer of the anus, anal canal, and anorectum during their lifetime. These statistics are called the lifetime risk. See Fast Stats for more detailed statistics, and Probability of Developing and Dying of Cancer for methodology.

What Are the Risk Factors for Anal Cancer?

• Human papillomavirus (HPV) infection: Most squamous cell anal cancers seem to be linked to infection by the human papilloma virus (HPV), the same virus thought to cause cervical cancer. There are several subtypes of the virus, but the one most likely to cause anal cancer is called HPV-16. This virus is most often spread by sexual contact and is more likely to be found in people who have had many sex partners. Different subtypes of HPV can cause genital warts (condylomas), but most people infected with HPV do not have genital warts.
• Sexual activity: Having multiple sex partners is a risk factor. Another risk factor is anal intercourse for both men and women, particularly younger than the age of 30.
• Smoking: Smoking also increases the risk of anal cancer. Current smokers are several times more likely to have cancer of the anus compared with people who do not smoke. Quitting smoking will reduce the risk. People who used to smoke but have quit are only slightly more likely to develop this cancer compared with people who never smoked.
• Lowered immunity/HIV infection: Higher rates of anal cancer occur among people with reduced immunity, such as people who have had an organ transplant and must take medicines that suppress their immune system. Another important risk factor is infection with the human immunodeficiency virus (HIV), the virus that causes AIDS. But effective drug treatment for HIV hasn't lowered the anal cancer rate in people infected with HIV.

Allison Margolin
Criminal Defense Attorney

Charles Lynch, a dispensary operator from Morro Bay, California, who was indicted and convicted in federal court for activities related to selling marijuana to medical patients, received a sentence last Thursday of a year and a day.

John Littrell, Lynch’s attorney, indicated that Lynch received what is known as the “safety valve.” This is a federal statute that allows for a defendant who is otherwise subject to mandatory minimum sentences to have a reprieve and be sentenced outside of them. In order to qualify for the so-called 'safety valve,' the defendant cannot be the “leader” of the organization. Littrell indicated the judge would issue a written order amidst objection by the U.S. Attorney to the safety valve in part on that basis.

He also indicated that Lynch was sentenced to 366 days in order to qualify for good time credits that would reduce Lynch’s sentence to around 10 months.

It is refreshing and fabulous that Judge Wu has liberally interpreted the safety valve to help reduce the prison exposure of a defendant who would have a medical defense in state court. Although the attorneys were precluded from mentioning the medical defense during Lynch’s jury trial, it is clear that his medical defense, though not technically available, motivated the court to sentence the defendant far below the 10-year-mandatory minimum that would otherwise apply to his convictions.

I believe that defense attorneys should use this case as well as USA v. Landa, 281 F. Supp. 2d 1139 (2003) , in which the district court contemplated compliance with state law as a basis for a downward departure in the guidelines (although that case lacked evidence of state law compliance), to argue that state law has a place in contemplating punishment when the state and federal law differ and the state gives more rights than the federal government.

I drafted a motion like this for Stephanie Landa on her appeal. For anyone interested, the argument is that the 10th Amendment is violated by the federal enforcement of marijuana’s Schedule I status in the medical states.

A few weeks ago, the New York Times Magazine published an article, “Obama’s Judicial Philosophy Analyzed,” by Charlie Savage, about what the author perceived to be Obama’s judicial philosophy and the one he believed Supreme Court justices appointed by Obama would follow.

The article suggested that Obama is interested in a court who articulates rights that many states (maybe a super-minority) have recognized, and pushes the other states along. That is why the recent legalization of medical marijuana in Rhode Island should be celebrated as a victory and replicated in more states.

Then we can use federal marijuana cases as a vehicle to go back to the U.S. Supreme Court and ask that the use of marijuana for medical purposes be recognized as a right that is held superior to the ban of the conduct by the Controlled Substances Act, the statute that regulates controlled substances and places marijuana in a category that has no medical use, Schedule I.

Government spending on health care is growing at an alarming rate.

If recent trends continue, the two main government programs, Medicaid and Medicare, will increase from 6 percent of the nation's Gross Domestic Product now to about 15 percent by 2040.

This means that, without policy changes, the United States faces enormous budget deficits, substantially higher taxes, or huge cuts in non-health spending.

No one wants higher deficits or taxes, and there is no consensus about cutting other spending. The only way to avoid some combination of these outcomes, however, is to reduce the growth rate of what we spend on health. The question, of course, is how?
