PNEUMONIA AND DIARRHEA


Biggest child-killers: pneumonia and diarrhea

Although treatable, these illnesses claim more lives than HIV and malaria

Children collect stagnant water for use at home Dec. 7, 2008, in Glen View, Harare, Zimbabwe.
Diarrheal diseases, such as cholera and rotavirus, kill 1.5 million kids each year, most under 2 years old.
Often they get sick from drinking dirty water.

HANOI, Vietnam -
Diarrhea doesn't make headlines. Nor does pneumonia.
AIDS and malaria tend to get most of the attention.
Yet even though cheap tools could prevent and cure both diseases, they kill an estimated 3.5 million kids under 5 each year globally — more than HIV and malaria combined.
"They have been neglected, because donor or partnership mechanisms shifted their emphasis to HIV and AIDS and other issues," said Dr. Tesfaye Shiferaw, a UNICEF official in Africa.
"These age-old traditional killers remain with us.
The ones dying are the children of the poor."

Global spending on maternal, newborn and child health was about $3.5 billion in 2006, according to a report by the Bill & Melinda Gates Foundation.
That same year, nearly $9 billion was devoted to HIV and AIDS, according to UNAIDS.
Pneumonia is the biggest killer of children under 5, claiming more then 2 million lives annually or about 20 percent of all child deaths.
AIDS, in contrast, accounts for about 2 percent.
If identified early, pneumonia can be treated with inexpensive antibiotics. Yet UNICEF and the World Health Organization estimate less than 20 percent of those sickened receive the drugs.
A vaccine has been available since 2000 but has not yet reached many children in developing countries.
The GAVI Alliance, a global partnership, hopes to introduce it to 42 countries by 2015.
Diarrheal diseases, such as cholera and rotavirus, kill 1.5 million kids each year, most under 2 years old.
The children die from dehydration, weakened immune systems and malnutrition. Often they get sick from drinking dirty water.
The worst cholera outbreak to hit Africa in 15 years killed more than 4,000 people in Zimbabwe last year.
The country recently reported new cases of the waterborne disease, and more are expected as the rainy season peaks and sewers overflow.
Rotavirus, a highly contagious disease spread through contaminated hands and surfaces, is the top cause of severe diarrhea, accounting for more than a half million child deaths a year.
A vaccine routinely given to children in the U.S. and Europe is expected to reach 44 poorer countries by 2015 through the GAVI Alliance.
"Every child in the United States gets it, even though they have access to clean water and hygiene," said John Wecker, of the Program for Appropriate Technology in Health, a Seattle-based nonprofit that is part of the vaccine alliance.
"The only effective way to prevent these deaths is through vaccination."
Diarrheal diseases received more attention in the 1980s and 1990s, he said, but interest has waned or been diverted elsewhere, allowing them to creep back.

"How did the leading killers end up at the bottom of the global health agenda?
I don't know," Wecker said at a recent GAVI meeting in Hanoi.
"We've got the tools. We're not looking for the next technological breakthrough. It's here now and it's not being used."
Death can often be prevented by giving children fluid replacement, a simple recipe of salt and sugar mixed with clean water to help ward off dehydration.
Yet 60 percent of children with diarrhea never receive the concoction, according to a WHO and UNICEF report released last month.
"It is so preventable," said Dr. Richard Cash, a Harvard University expert who helped develop the oral rehydration therapy 40 years ago.
"Preventing the deaths is at the very least what we should be striving for."

Extrañas luces en el cielo de Noruega











Doce minutos de misteriosas espirales
El Instituto de Meteorología de Noruega ha recibido miles de llamadas de personas anónimas alertando del fenómeno.
Hace unos días apareció una luz con extrañas formas espirales que iluminó el cielo durante unos doce minutos, para luego expandirse y desaparecer. Meteorólogos, astrónimos y hasta las Fuerzas Armadas buscan una solución. Los científicos del país nórdico son incapaces de explicar su origen. Algunos expertos han especulado con la posibilidad de que haya sido causada por un cohete o misil ruso fuera de control. La embajada rusa en Noruega ya ha desmentido el rumor. Otras hipótesis apuntan al choque entre un cohete y un asteroide. También hay quienes culpan al cambio climático, quienes las atribuyen a los extraterrestres o quienes dicen que se trata de rastros químicos... pero lo cierto es que aún no hay una explicación lógica para este misterio.

WHY WHALES BEACH THEMSELVES




Nobody knows why whales beach themselves.


Humans try to save them, but some of the whales return to the beach to die.

POLLUTION

This coal-fired power plant in Macedonia, seen on Dec. 10 as pigs feed on a nearby trash dump, is one of thousands around the world that emit large quantities of carbon dioxide.
Thick smoke from a coal-fired oven fills the air in this neighborhood of Calcutta, India, on Dec. 9. Coal burning is a key source of manmade carbon dioxide emissions.

Iceberg B17B, top left, floats in the Ross Sea near Antarctica after it broke off from the Ross Ice Shelf nearly 10 years ago. The monster iceberg, at 12 miles long and 5 miles wide nearly twice the size of Hong Kong, has been slowly drifting toward Australia in what scientists call a once-in-a-century event. It is now about 1,100 miles southwest of Australia. Accelerated glacial and ice shelf melt and collapses have been tied to global warming.

CHRISTMAS AT THE WHITE HOUSE 2009


The entrance to the West Wing of the White House is framed by Christmas trees and holiday lights in Washington. Jacqueline Kennedy in 1961 began the tradition of establishing a decorating theme for White House Christmases, selecting "The Nutcracker Suite."




Christmas trees are seen on the White House's State Floor.


White House pastry chef Bill Yosses poses next to a marzipan and chocolate sculpture of the executive mansion in the White House's State Dining Room. This year's 56-inch-by-29-inch recreation of the White House weighed in with 140 pounds of gingerbread coated with 250 pounds of white chocolate.



The Blue Room is adorned with a Fraser fir from Dan and Bryan Christmas Trees in nearby Shepherdstown, W. Va. The first known Christmas tree at the White House was during the tenure of Benjamin Harrison, who helped trim one in the upstairs library with friends, family and staff. "We shall have an old-fashioned Christmas tree for the grandchildren upstairs and I shall be their Santa Claus myself," Harrison exclaimed.

The Red Room of the White House is seen during a Christimas tour of the famous residence. Overall, there appear to be fewer trees and decorations than in years past -- and the same is true of the Christmas card list. Several hundred thousand have been mailed out, paid for by the Democratic National Committee.


Lights shine on the National Christmas Tree in front of the White House on Dec. 1 in Washington. President Barack Obama, first lady Michelle, and daughters Malia and Sasha, helped press the button to light the illuminate the Colorado blue spruce.
