Colic folk remedies do not work, review says

That nonstop crying of a baby with colic has some parents turning to popular folk remedies. Unfortunately, there's no good evidence they work, according to a review of 15 studies.

The results don't surprise New York City mom Leni Calas, 32. She tried many treatments studied, including fennel extract, sugar drops and massage, and says nothing worked for baby Roxy, who cried almost nonstop for six months.

"Our daughter would wake up and cry literally morning to night without napping," Calas said. "She would just literally scream herself purple, and then throw up because she had been screaming so much."

Calas said she and her husband couldn't accept what doctors told them — that there was nothing wrong with their baby and that she'd outgrow the crying spells. But that's exactly what happened.

And that's what most doctors believe about colic, which affects up to roughly 20 percent of U.S. babies, usually in the first few months of life.

If a physical problem can be found, the condition is usually not considered colic. Gastric reflux and protein allergies are among conditions that can cause digestive upsets and crying spells in babies, and are often mistakenly called colic.

That may explain why some remedies thought to ease digestive problems may not work in babies with true colic, including alternative treatments containing fennel, herbal teas and probiotics, which all were included in the medical review.
Fifteen studies reviewed

Alternative remedies are not tested and approved by the federal government, and the purity and amounts of their ingredients are not always verified. Parents should always check with their pediatricians if they plan to give their children an alternative treatment, said Dr. Jatinder Bhatia, head of the American Academy of Pediatrics nutrition committee.

The study by researchers at the University of Exeter in England was published online Monday in Pediatrics. The researchers analyzed results from 15 studies on various alternative remedies, massage and chiropractic methods advertised as effective against colic. Overall, almost 1,000 infants were involved.

Few of the studies were rigorously conducted and all had "major limitations," the researchers said.

"Thus, the notion that any form of complementary and alternative medicine is effective for infantile colic is currently not supported from the evidence" studied, they said.

None of the studies reported side effects, but one involving an herbal remedy listed vomiting, constipation and other symptoms possibly related to the treatment.

Although there were promising signs with a few treatments, including fennel extract, herbal teas and sugar solutions, better research is needed to provide conclusive evidence, said researcher Rachel Perry, the review's lead author.

Bhatia, a professor at Georgia Health Sciences University, said the study results don't mean that none of the treatments will work for any baby. Some parents do report success with alternative remedies. Sometimes that might be because parents think it will work and they feel calmer, which can in turn calm the baby — a placebo effect.

Parents should always check with their pediatricians if they plan to give their children an alternative treatment, said Bhatia.

For Leni Calas' baby Roxy, now almost 2, the incessant crying spells tapered down and by 9 months disappeared.

Calas said she's convinced of one thing "that no one wants to hear — that the only thing that really does cure it is time."

High bacteria levels in bean sprouts

For many, the sprout is the epitome of a healthy food: rich with vitamins, minerals, proteins, not to mention crunchy, tasty and green.

But research by CBC's investigative team (I-Team) that included an analysis by a University of British Columbia expert has found high levels of bacteria in packaged sprouts, enough to make consumers turn green.

Sprouts, including mung beans and alfalfa sprouts, have become a common food item in grocery stores, salad bars and Asian dishes across Canada.

For Peggy LaLune, who made a stirfry for her family last summer, the only difference between hers and the one she served her son was that his did not contain sprouts.

Within a few hours, LaLune was doubled over with cramps and stomach pains.

"It was horrible, and I ended up getting really, really sick throughout the night," she said.

"I couldn't venture very far from the washroom, and at one point it was so bad that I thought I was going to have to yell to my son to come and get me and take me to the hospital."

According to Health Canada, most sprouts, including alfalfa sprouts, can only be eaten raw. This means they are not exposed to temperatures high enough to kill any possible bacteria.
Fecal contamination

The I-Team asked Kevin Allen, a microbiology professor at the University of British Columbia, to test 44 packages of sprouts from across the country.

"What we were looking at was whether the produce is dirtier than it should be [and] in some of the cases, we certainly saw this," he said.

There was no salmonella but Allen found 93 per cent tested positive for bacteria, and in some cases, high levels of enterococci bacteria, which is an indicator of fecal contamination.

"They [bacteria found] come from our intestinal tract and we don't want the contents of our intestinal tract on our food," he said.

If ingested, the bacteria aren't generally harmful to healthy people, but for those with weakened immune systems, it could reduce the effectiveness of antibiotics and allow for the spread of disease.

Sprouts are particularly susceptible to contaminants because they are grown in moist, warm environments, which are ideal for the rapid growth of bacteria, Allen said, adding that washing them before consuming them likely wouldn't help.

Seeds may become contaminated by animal manure in the field or during storage, and poor hygienic practices in the production of sprouts have also caused some outbreaks of food-borne illness in the past, according to Health Canada.

"Personally, I don't consume sprouts and I would not feed them to my children, either," Allen said.

But it wasn't just the packages of sprouts that contained the unwelcome, extra contents.

Allen also tested 106 samples of bagged veggies and found 79 per cent of the herbs and 50 per cent of the spinach had similar bacterial contamination.

Thoroughly cooking those products is the best way to kill the bacteria.

Food dye risks need more study: U.S. panel

An advisory panel to the U.S. Food and Drug Administration has recommended that the agency further study the link between food colouring and childhood hyperactivity, but said products that contain the dyes do not need package warnings.

The committee, made up of doctors, academics and consumer representatives, narrowly voted 8-6 that food packages don't need warnings flagging food colourings that could affect attention deficit disorder in children. Packages now must list the food colourings, but there is no warning about a possible link to hyperactivity.

The panel agreed with the FDA and affirmed that there is not enough evidence to show that certain food dyes cause hyperactivity in the general population of children. They also agreed that diets eliminating food dyes may work for some children.

Health Canada is completing its review of comments received during a 2010 consultation on proposed improvements to labelling of food dyes. The department encourages food manufacturers to voluntarily declare food colours by their individual common names on food labels.

Yuri Gagarin’s 1961 flight into Outer Space

Soviet pilot and cosmonaut Yuri Gagarin became the first human to travel into space on 12 April 1961, handing a propaganda coup to the Soviet Union. Here are some facts about his historic mission.

* The flight lasted 108 minutes from launch to landing and orbited the Earth once.

* The mission was called Vostok 1 after the type of Soviet spacecraft it was carried out in.

* Some sources claimed afterwards that Gagarin had remarked during the flight “I don’t see any God up here.” But no such words were recorded in the official transcript of the flight and his friends later said the phrase had originated from an anti-religion speech given by Soviet leader Nikita Khrushchev.

* Gagarin was made a Hero of the Soviet Union for the flight and quickly became a global celebrity touring the world.

* Gagarin claimed to have whistled a patriotic song called “The Motherlands Hears, The Motherland Knows” during re-entry.

Report: Windows 8 seeds being sent to PC makers

A report says Microsoft is already sending early versions of Windows 8 to PC makers so they can get ready for an expected launch in 2012.

According to Microsoft news-and-rumors siteWinRumors, Microsoft has begun seeding selected manufacturers with early builds of Windows 8 so they can get ready for the operating systems’ general release, currently expected for sometime in 2012. According to the report, Microsoft is seeding a “milestone 3″ build to Hewlett-Packard and other vendors

Microsoft has had relatively little to say in public about Windows 8: after all, the company is still riding high on the retail success of Windows 7. At the beginning of the year, the company said it had sold more than 300 million copies of the operating system, although that figure was a little below estimates as sales of tablets and smartphones ate into netbook sales, a product category Microsoft’s CFO characterizes as “past their prime.”

Last year, Microsoft’s Dutch Web site made a fleeting reference to a 2012 timeframe for Windows 8; past that, the only real indication of a Windows 8 release date is that Microsoft’s server team was gearing up for a major release in 2012. Releases of Windows Server typically follow shortly on the heels of major desktop operating system releases. Other information has been limited to industry speculation, a purported series of leaked screenshots, and rumors that Microsoft and OEM manufacturers are working on Windows 8 tablets, possibly for a 2012 release.

To date, the only real information about Windows 8 is that Microsoft plans to support ARM CPUs in addition to Intel-based processors, a move that bolsters the notion that Microsoft is targeting portable devices like tablets and “slates” as well as traditional desktop and notebook computers.

Yahoo! takes on Google, social networking sites

Hyderabad, : Once a favourite with Indian Internet users, who later shifted loyalties, Yahoo! seems to be in a reload phase to win back the lost ground and take competition from Google and social networking sites head on.

The mail, search and news portal has lined up Search Direct for release in the second half of this year. The service, which targets Google's prompt-based search, will provide answers based on the user needs.

“Users do not come to a search engine with just search strings. They expect some useful information. For one, if you type Spiderman, you may specifically be looking for reviews on the film, film tickets, pictures or news,” Mr Prabhakar Raghavan, Chief Scientist and Senior Vice-President and Head of Yahoo! Labs, said.

Like in Google search, one will get prompts. But the similarity ends there. “You will get answers as categories as you begin to key in the search string. You can directly go to the category,” he said.

Mr Prabhakar, who was here to take part in the 20th World Wide Web Conference, said Yahoo! registered 30 million users a month in India and 74 per cent of all the net users in the country. With the user base growing, the company is planning to replicate a survey it conducted in the US to measure effectiveness (of Web content, including advertisements).

The company, which claims it registers 100 crore clicks every day in its homepage in India, said its Content Optimisation tool would allow users to see content based on their preferences.

The hybrid model picks trends based on the patterns in ‘clicks' and gives editors tools to pick relevant content.

The tool, which at present is offered to English users, would be expanded soon to its regional content, which was not so dynamic.

On Yahoo! facing competition not just from Google or MSN but also from social networking sites, he said the company is working on a Status message option to allow users to collaborate in smaller groups.

By picking threads from the message sharing pattern, users can talk on a one-to-a-few basis as against one-to-many in social networking sites.

Mr Prabhakar said the Internet should be open and any efforts to stack on the basis of Operating Systems and exclusive applications could defeat the spirit of the Web that was built on openness.

Of its total workforce of 14,000 globally, Yahoo! has 2,000 employees at its R&D facility in Bangalore.

Kalam's Web mantra for societal transformation

HYDERABAD, INDIA: "Don't keep forever on the public road, going only where others have gone. Leave the beaten track occasionally and dive into the woods. You will be certain to find something you have never seen before. It will be a little thing, but do not ignore it. Follow it up, explore all around it; one discovery will lead to another, and before you know it, you will have something worth thinking about...”

With this quote from Alexander Graham Bell, Dr. APJ Abdul Kalam, former President of India, started his keynote address at the 20th International Worldwide Web Conference, Hyderabad, on Wednesday.

Dr. Kalam centered his keynote address around "Web for societal transformation". Addressing the over 700 delegates he said the Web has had a glorious existence over two decades and has revolutionized the way we work and live.

"It has been the catalyst for proliferating information across boundaries, enabling effective communication and 24/7 service availability, all leading to a digital, information-based economy that we have today."

However, he said, its direct influence has reached only a small percentage of human population. He advised Indian enterprises to adopt a mindset to spread their wings to reach to the unreached by a mix of global approach with a local cultural accent. "That would enrich all the sectors of the economy thereby promoting economic progress in the developing world."

The ordinary citizen in a rural area, by proper communication and appropriate tools, may have to be convinced that the investment and time on World Wide Web is indeed useful for ultimately increasing his/her per-capita income. They must feel that the value-added service is worth extending their native knowledge, increasing their productivity, opening new horizons for themselves and their children, he added.

"Suppose a farmer or a home maker in a village using his or her mobile phone, should be able to ask a question in the local language. This question would be translated into multitudes of other languages used for searching the knowledge base. It should cull out the right information instead of giving tonnes of irrelevant data for a certain type specific question or key words or combination of both in verbal form,” he said.

“The culled out information may be collated, they translate them back to the language in which the query was raised and human like voice output with the friendliness and affection of a teacher is transmitted to the phone all in a blink,” added Kalam.

He asked researchers to think of building such a system or standard or tool using the emerging Web 3.0 technologies which is called Semantic Web, so that machines can perform more of the tedious work involved in finding, combining, and acting upon information on the web.

“A new revolution will set in to make a difference to the life of the common man using the Web 3.0 technologies. It has a direct impact on the lives of the 700 million people who are living in the rural areas and will benefit a number of other developing countries using the mobile device as their Personal Knowledge Assistant, instead them having to learn to use the computer to access the necessary right information in right time,” he said
