Indian woman gives birth to ‘miracle’ child

‘An Indian woman has given birth to baby girl with four eyes and two faces, just two years after the world was captivated by the story of Lakshmi Tatma, the “twin” girl born with four arms and four legs.

The four-day old baby girl, born to Vinod Singh and his partner Sushma, is already being hailed as a reincarnation of the Indian God Ganesha. [..]

As news of her birth spread through the secluded rural village where her family reside, local residents began singing and dancing and asking for her blessings.

According to the doctor at the hospital, the baby girl and her mother are both in good health.’

Hacking attacks can turn off heart monitors

‘American researchers have proven it’s possible to maliciously turn off individuals’ heart monitors through a wireless hacking attack.

Many thousands of people across the world have the monitors, medically known as implantable cardiac defibrillators (ICDs), installed to help their hearts beat regularly.

ICDs treat abnormal heart conditions; more recent models also incorporate the abilities of a Pacemaker. Their function is to speed up a heartbeat which is too slow, or to deliver an electrical shock to a heart which is beating too quickly.

According to the research (pdf) by the Medical Device Security Center – which is backed by the Harvard Medical School among others – hackers would be able to intercept medical information on the patient, turn off the device, or, even worse, deliver an unnecessary electrical shock to the patient.

The hack takes advantage of the fact the ICD possesses a radio which is designed to allow reprogramming by a hospital doctor. The ICD’s radio signals are not encrypted, the Security Center said.’


50 people looking for solar image of Mary lose sight

‘At least 50 people in Kottayam district have reportedly lost their vision after gazing at the sun looking for an image of Virgin Mary.

Though alarmed health authorities have installed a signboard to counter the rumour that a solar image of Virgin Mary appeared to the believers, curious onlookers, including foreign travellers, have been thronging the venue of the ‘miracle’

St Joseph’s ENT and Eye Hospital in Kanjirappally alone has recorded 48 cases of vision loss due to photochemical burns on the retina. “All our patients have similar history and symptoms. The damage is to the macula, the most sensitive part of retina. They have developed photochemical, not thermal, burns after continuously gazing at the sun,” Dr Annamma James Isaac, the hospital’s ophthalmologist, said. [..]

The health department has now put up a signboard at the hotelier’s house near Erumeli, where the divine image is said to have appeared, warning people against exposing their eyes to sunlight.’

Woman sits on boyfriend’s toilet for 2 years

‘Deputies said a woman in western Kansas sat on her boyfriend’s toilet for two years, and they’re investigating whether she was mistreated.

Ness County Sheriff Bryan Whipple said a man called his office last month to report that something was wrong with his girlfriend.

Whipple said it appeared the 35-year-old Ness City woman’s skin had grown around the seat. She initially refused emergency medical services but was finally convinced by responders and her boyfriend that she needed to be checked out at a hospital.

“We pried the toilet seat off with a pry bar and the seat went with her to the hospital,” Whipple said. “The hospital removed it.”‘

Abortion tablets in wife’s food

‘A baker who put abortion tablets into his wife’s breakfast to try to make her lose their baby has been jailed.

Gil Magira, 36, crushed the tablets into his 38-year-old wife Anat Abraham’s sandwich, a bowl of cereal and a yoghurt, the Old Bailey was told.

Mrs Abraham suffered pain and bleeding but the child survived unharmed.

Magira, of Holmebrook Drive, Hendon, north London, admitted “using an instrument to procure a miscarriage” – the first such charge in 30 years. [..]

His wife said she feared for her life – and that of the child – when she realised what he had done.

“What made it worse was how desperate and determined he was to try to kill the baby that I already felt moving inside me,” she said.’


Famous assassinations: Who could doctors save today?

‘Would Julius Caesar or John F. Kennedy have survived if they were attacked in Billings today?

Dr. Terry Housinger, a general surgeon at the Billings Clinic, tackled the topic of famous assassinations at a meeting of the History of Medicine Club, offering his audience of medical students and doctors a chance to reflect on the evolution of trauma care.

After describing the circumstances surrounding each famous assassination, Housinger offered his opinion on whether modern medicine could have saved those high-profile victims if the attack had occurred in Billings today.’

AFP raid homes of euthanasia planners

‘The Australian Federal Police (AFP) is under fire after raiding the homes of two Victorians suffering from terminal illnesses.

Controversial euthanasia campaigner Doctor Philip Nitschke says AFP officers executed search warrants on 78-year-old Don Flounders of Warragul, and 54-year-old Angie Belecciu of Hastings on Wednesday after the pair announced on television they planned to end their own lives.

Mr Flounders suffers from the asbestos-related disease mesothelioma and Ms Belecciu is terminally ill with breast cancer.

Dr Nitschke says he received a panicked phone call from Mr Flounders this morning as the AFP raids were taking place.

“He called me saying ‘there are people in my house, what do I do’,” Dr Nitschke said.’

The teenage girl who is allergic to WATER

‘Teenager Ashleigh Morris can’t go swimming, soak in a hot bath or enjoy a shower after a stressful day’s work – she’s allergic to water.

Even sweating brings the 19-year-old out in a painful rash.

Ashleigh, from Melbourne, Australia, is allergic to water of any temperature, a condition she’s lived with since she was 14.

She suffers from an extremely rare skin disorder called Aquagenic Urticaria – so unusual that only a handful of cases are documented worldwide.

When Ashleigh gets wet her body explodes in sore, itchy red lumps that take about two hours to ease.

She has to wash. But showering is a painful experience and she can only do it for a minute at a time.’

Prozac, used by 40m people, does not work say scientists

‘Prozac, the bestselling antidepressant taken by 40 million people worldwide, does not work and nor do similar drugs in the same class, according to a major review released today.

The study examined all available data on the drugs, including results from clinical trials that the manufacturers chose not to publish at the time. The trials compared the effect on patients taking the drugs with those given a placebo or sugar pill.

When all the data was pulled together, it appeared that patients had improved – but those on placebo improved just as much as those on the drugs.’

California court: Medical pot not OK at work

‘Employers can fire workers who use medical marijuana even if it was legally recommended by a doctor, the California Supreme Court ruled Thursday, dealing the state another setback in its standoff with federal law enforcement.

The high court upheld a small Sacramento telecommunications company’s firing of a man who flunked a company-ordered drug test. Gary Ross held a medical marijuana card authorizing him to use the drug to treat a back injury sustained while serving in the Air Force.

The company, Ragingwire Inc., argued that it rightfully fired Ross because all marijuana use is illegal under federal law, which does not recognize the medical marijuana laws in California and 11 other states.

The justices upheld that argument in a 5-2 decision.’

Battling for life, the baby born with its heart OUTSIDE its chest

‘A newborn baby has survived delivery despite its heart being outside the chest cavity.

The infant’s heart was born with its most vital organ exposed and is being treated in the intensive care unit of Shenzhen Children’s Hospital in China’s Guangdong Province.

The parents knew about the condition before the baby was born, but chose not to abort it.

The unusual and dangerous development was caused by a rare disease – less than five babies in one million are struck by it. The illness affects the child’s chest and abdomen.

Less than 200 cases have been recorded and it is the first modern case in China.

Most babies die from the disease before birth.

Doctors are expected to operate to repair the malformation when the infant is strong enough.’

Female G spot ‘can be detected’

‘The mysterious G spot – supposedly a route to female sexual satisfaction – can be located with ultrasound, claim Italian scientists.

Some women say stimulating a certain part of the vagina triggers powerful orgasms, but medicine has not been able to pin down the exact location.

Researchers told New Scientist magazine they found an area of thicker tissue among the women reporting orgasms.

But specialists warned there could be other reasons for this difference.’

Scientists Make First Map Of Emerging-Disease Hotspots

‘An international research team has provided the first scientific evidence that deadly emerging diseases have risen steeply across the world, and has mapped the outbreaks’ main sources. They say new diseases originating from wild animals in poor nations are the greatest threat to humans. Expansion of humans into shrinking pockets of biodiversity and resulting contacts with wildlife are the reason, they say. Meanwhile, richer nations are nursing other outbreaks, including multidrug-resistant pathogen strains, through overuse of antibiotics, centralized food processing and other technologies. The study appears in the Feb. 21 issue of the leading scientific journal Nature.

Emerging diseases–defined as newly identified pathogens, or old ones moving to new regions–have caused devastating outbreaks already. The HIV/AIDS pandemic, thought to have started from human contact with chimps, has led to over 65 million infections; recent outbreaks of SARS originating in Chinese bats have cost up to $100 billion. Outbreaks like the exotic African Ebola virus have been small, but deadly.’

A&E patients left in ambulances for up to FIVE hours ‘so trusts can meet government targets’

‘Seriously ill patients are being kept in ambulances outside hospitals for hours so NHS trusts do not miss Government targets.

Thousands of people a year are having to wait outside accident and emergency departments because trusts will not let them in until they can treat them within four hours, in line with a Labour pledge.

The hold-ups mean ambulances are not available to answer fresh 999 calls.

Doctors warned last night that the practice of “patient-stacking” was putting patients’ health at risk.

Figures obtained by the Liberal Democrats show that last year 43,576 patients waited longer than one hour before being let into emergency units.’


Ivory Coast’s ‘big-bottom’ craze

‘A national dance craze in Ivory Coast has spawned a black market in treatments claiming to increase one’s bottom size.

The dance in question has been inspired by DJ Mix and DJ Eloh’s hit song Bobaraba, which means “big bottom” in the local Djoula language.

When it plays you can be guaranteed that the dance floor will be packed with people shaking their derrieres.

Even Ivorian footballers have adopted the moves and could be seen wiggling their bottoms in a curious on-pitch dance after each goal scored during the just-ended Africa Nations Cup.

However, doctors have warned of the possible dangers of some of the concoctions on sale. ‘

US meat recalled after mad cow concerns

‘It is the biggest food recall in US history. About 65 million kilograms of beef products from a Californian slaughterhouse have been recalled because of concerns about the plant’s production line.

Some animals were unable to stand and that has prompted concerns about their ability to be tested for infections like mad cow’s disease.

The plant is now under investigation and two of its employees have been charged with animal cruelty.

Everything from sirloin to taco meat has been recalled, as have some of the more curious by-products of the beef industry such as salivary glands and six gallon containers of beef bile.’

Tick saliva protein blocks HIV-1

‘A U.S. study said a protein in the saliva of deer ticks prevents HIV-1 from attaching to the surface of white blood cells called T Cells.

Researchers at the University of Massachusetts Amherst said the finding may lead to new treatments for autoimmune diseases and prevent rejection of organ transplants, the university said Friday in a release.

The researchers said the HIV-1 virus cripples the human immune system by targeting T cells that form the body’s first line of defense in fighting infection. Deer tick saliva contains the protein Salp15, which stops T cells from activating by binding to a specific site on their surface called the CD4 receptor.’

Genetic Breakthrough Creates Immunity to Viruses

‘Scientists at Canada’s McGill University have discovered a way to boost an organism’s natural anti-virus defenses, effectively making its cells immune to influenza and other viruses. In effect, this makes the cells immune to flu and other viruses.

The researchers performed their study with mice, and knocked out two key genes that repress production of interferon. Without these repressor genes, the mouse cells produced much higher levels of interferon, which effectively blocked viruses from reproducing. The researchers tested the process on influenza virus, encephalomyocarditis virus, vesicular stomatitis virus and Sindbis virus.

“People have been worried for years about potential new viral pandemics, such as avian influenzas,” Dr. Sonenberg, the study’s lead author, said in a press release issued by McGill University. “If we might now have the means to develop a new therapy to fight flu, the potential is huge.”‘

Wheelchair Crosswalk Prank

What happens when you pretend to be a paraplegic and get people to help push you across the road?

What happens if you fall out of the chair mid way and make them carry you the rest of the way across the road?

And then what happens if you stand up and start walking once you get to the other side?

Warning over cannabis lung harm

‘Heavy cannabis users may be at greater risk of chronic lung disease – including cancer – compared to tobacco smokers, two studies suggest.

One study found a higher risk of lung cancer for those who smoked one joint a day compared with those who smoked 20 cigarettes a day over the same period.

Another found bullous disease – a form of emphysema – occurs 20 years earlier in cannabis smokers.

The studies appear in Respirology and the European Respiratory Journal.’

Study finds high levels of chemicals in infants using baby cosmetics

‘Infants and toddlers exposed to baby lotions, shampoos and powders carry high concentrations of hormone-altering chemicals in their bodies that might have reproductive effects, according to a new scientific study of babies born in Los Angeles and two other U.S. cities.

The research, to be published today in the medical journal Pediatrics, found that as the use of baby care products rose, so did the concentration of phthalates, which are used in many fragrances.

The lead scientist in the study, Dr. Sheela Sathyanarayana of the University of Washington’s Department of Pediatrics, said the findings suggested that many baby care products contain a variety of phthalates that enter children’s bodies through their skin.’


The vasectomy you can switch on and off at the push of a button

‘Vasectomies could be a thing of the past thanks to a remotecontrolled implant that can stop the flow of sperm.

The valve-like device can be opened and shut at the press of a button, using the same technology that locks a car using a key fob.

Scientists who invented the implant say it could be used as a form of male contraception.

Men who change their minds about having children would then simply point the remote handset at their testicles and press a button to open up the valve. [..]

Once the handset is pressed, it sends a coded radio signal through the skin to the implant, which contains a tiny antenna. The antenna picks up the signal and converts it into sound waves that “ripple” through the valve.

Since the valve itself is soft and flexible, the sound waves make it flap open – allowing sperm to pass through. As with cars, each device would have its own unique code so it could not be opened by anyone else.’

Pup chews off paralyzed man’s toes

‘A paralyzed Lexington man was rushed to the hospital Tuesday after he woke to find his dog had chewed off parts of his toes, police said. [..]

Smith may be allowed to take China into quarantine at his home, animal control Chief Nathan Bowling said.

“The animal appears to be in great health, and we have no reason to believe there’s any kind of abuse,” Bowling said.

Tim Cantrell, who said he is temporarily staying at Smith’s home, said he saw the blood on his friend’s bed Tuesday morning.

“I realized upon closer inspection that his toes were no longer on his feet,” Cantrell said.’


The girl, 10, who could die from shock just by watching a scary film

‘Like most children her age, Jennifer Lloyd loves watching her favourite programmes on TV.

But when a scary bit is about to happen the ten-year-old has to leave the room quickly – because the sudden shock could kill her.

Jennifer is one of just six known sufferers of polyglandular Addison’s disease, which causes her to become ill whenever she is surprised or shocked.

The condition means she is unable to produce adrenaline in response to alarm or any sudden form of emotional or physical stress.

Instead her body goes into shock and her organs could shut down unless she receives medical treatment.’

Finnish patient gets new jaw from own stem cells

‘Scientists in Finland said they had replaced a 65-year-old patient’s upper jaw with a bone transplant cultivated from stem cells isolated from his own fatty tissue and grown inside his abdomen.

Researchers said on Friday the breakthrough opened up new ways to treat severe tissue damage and made the prospect of custom-made living spares parts for humans a step closer to reality.

“There have been a couple of similar-sounding procedures before, but these didn’t use the patient’s own stem cells that were first cultured and expanded in laboratory and differentiated into bone tissue,” said Riitta Suuronen of the Regea Institute of Regenerative Medicine, part of the University of Tampere.’

I hope the people in favour of banning stem cell research have their jaws fall off. That’ll teach ’em. 🙂 No new jaws for you, motherfuckers.

Link Between Smoking In Pregnancy And Sudden Infant Death Syndrome Explained

‘Researchers at McMaster University have found a mechanism that explains why an infant’s ability to respond to oxygen deprivation after birth–or a hypoxic episode–is dramatically compromised by exposure to nicotine in the womb, even light to moderate amounts.

“While cigarette smoke contains many different compounds, we found there is a direct impact of one component, nicotine, on the ability of certain cells to detect and respond to oxygen deprivation,” says Josef Buttigieg, lead author and a PhD graduate student in the department of Biology. “When a baby is lying face down in bed, for example, it should sense a reduction in oxygen and move its head. But this arousal mechanism doesn’t work as it should in babies exposed to nicotine during pregnancy.”‘

Blue-eyed humans have a single, common ancestor

‘New research shows that people with blue eyes have a single, common ancestor. A team at the University of Copenhagen have tracked down a genetic mutation which took place 6-10,000 years ago and is the cause of the eye colour of all blue-eyed humans alive on the planet today.

“Originally, we all had brown eyes”, said Professor Eiberg from the Department of Cellular and Molecular Medicine. “But a genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a “switch”, which literally “turned off” the ability to produce brown eyes”. The OCA2 gene codes for the so-called P protein, which is involved in the production of melanin, the pigment that gives colour to our hair, eyes and skin. The “switch”, which is located in the gene adjacent to OCA2 does not, however, turn off the gene entirely, but rather limits its action to reducing the production of melanin in the iris – effectively “diluting” brown eyes to blue. The switch’s effect on OCA2 is very specific therefore. If the OCA2 gene had been completely destroyed or turned off, human beings would be without melanin in their hair, eyes or skin colour – a condition known as albinism.’

Kidney Thefts Shock India

‘As the anesthetic wore off, Naseem Mohammed said, he felt an acute pain in the lower left side of his abdomen. Fighting drowsiness, he fumbled beneath the unfamiliar folds of a green medical gown and traced his fingers over a bandage attached with surgical tape. An armed guard by the door told him that his kidney had been removed.

Mr. Mohammed was the last of about 500 Indians whose kidneys were removed by a team of doctors running an illegal transplant operation, supplying kidneys to rich Indians and foreigners, police officials said. A few hours after his operation last Thursday, the police raided the clinic and moved him to a government hospital.

Many of the donors were day laborers, like Mr. Mohammed, picked up from the streets with the offer of work, driven to a well-equipped private clinic, and duped or forced at gunpoint to undergo operations. Others were bicycle rickshaw drivers and impoverished farmers who were persuaded to sell their organs, which is illegal in India.’

Crew dragged co-pilot off jet at Shannon after mid-air scare

‘More than a hundred passengers aboard an Air Canada flight from Toronto to London were forced to divert to Shannon yesterday after the co-pilot suffered what appeared to be a nervous breakdown in mid-air.

Officials at Shannon Airport last night confirmed that the male co-pilot was admitted to the psychiatric unit of the Ennis General Hospital in Co Clare yesterday after he was forcibly taken off the flight by fellow crew members and an off-duty member of the Canadian Armed Forces who assisted in restraining him.

Air Canada flight AC848, en route from Toronto’s Pearson International Airport to London Heathrow, was diverted to Shannon with less than an hour to go before reaching its intended destination after the co-pilot began “acting in a peculiar manner and was talking loudly to himself,” during the transatlantic crossing, according to aviation sources.’
