An outbreak of methicillin-resistant Staphylococcus aureus (MRSA) in a wing of the Women’s College Hospital in Toronto, Canada has resulted in the temporary closure of the hospital’s High Risk Perinatal Service in the Neo-natal Intensive Care Unit (NICU).

The NICU, operated by the Sunnybrook Health Sciences Centre, will not accept direct newborn admissions or maternal transfers, temporarily, until the outbreak is controlled. Current patients are being cared for in the NICU and Sunnybrook has created a separate area to accommodate new babies.

The closure of the NICU at Women’s College Hospital is expected to put a strain on availability of high-risk neo-natal services in Ontario. According to Sunnybrook, the NICU cares for one in five of all babies born in Ontario weighing less than three pounds.

Head of Sunnybrook’s department of newborn and developmental pediatrics, Dr. Michael Dunn, suggests that some patients of the NICU will need to be transferred to other facilities to allow for intensive cleaning of the area.

In a CBC interview, Dunn explains that, “all the babies who developed infections have been successfully treated, but we were not able to completely prevent the spread of the organism from one baby to another.”

New patients will have to be diverted to other facilities in the province of Ontario or even out of country. Buffalo, New York in the United States may be a potential destination for some women in Ontario with high-risk pregnancies or premature babies.

According to a Sunnybrook press release, the High Risk Perinatal Service will remain closed until there are no new transmissions of the Staphylococcus aureus bacterium. It further explains that outbreaks in the NICU are rare and that several measures have been put in place to keep the bacterium from spreading. The hospital has isolated babies who have symptoms and are ensuring that a specific team of clinicians only treat the affected babies.

The Sunnybrook press release suggests that, although MRSA bacteria are commonly found on the skin of newborns, the organism that has surfaced in the NICU has caused a variety of infections to the skin and eyes of the babies. The babies in the NICU are, apparently, responding to antibiotic treatment.

The Saskatoon Health Region in Saskatchewan, Canada recently discovered a fax machine problem which had not relayed almost 1,500 X-rays, Computed tomography (CT) and Magnetic resonance imaging (MRI) scans, ultrasounds, and other medical imaging test results to doctors.

The fax machine is part of the automated Radiology Information System. An audit revealed that medical diagnostic tests involving results dating back a decade have been affected by the broken fax machine.

On May 6, a doctor called the health region officials seeking follow up on a patient’s report. Staff who delved into it, found that the report was not sent from the system.

Now, two weeks later, this same patient has still not been contacted by the health region.

“It has taken some time to work with the patient’s physician. That was important — to get more information and more detail because we want that patient’s physician to be involved in the discussion with the patient,” Dr. David Poulin, vice-president of medical affairs for The Saskatoon Health Region, said. “This is a system error and that’s just what it was — an error. This doesn’t reflect in any way on the quality of work regional staff have done and continue to do.”

An internal review revealed that, of 2.2 million diagnostic tests performed, at least 1,380 had not been sent out by the malfunctioning fax machine.

The health region will embark on contacting each of the 1,380 patients and their physicians to make sure that the results have been received and if any health care was compromised.

Patients can also contact the health region via a newly set up hotline to make enquiries.

“We think it would actually be good practice if physician offices could have a system to check whether they have received important reports,” said Poulin, “The common practice appears to be in many doctors’ offices, particularly family physician offices, that they don’t respond to the report until it arrives. So, they basically are waiting for the report to arrive in their office by fax and it’s at that point that they look at it and decide what action to take.”

City Hospital, St. Paul’s Hospital and Royal University Hospital were the three city hospitals affected. Saskatoon has a population of roughly 233,923, and the hospitals also serve the surrounding rural areas.

Ironically the faulty fax machine was discovered the same week that provincial medical officials began to review approximately 70,000 radiology tests conducted in Yorkton. Officials there doubt the competence of the physician who first interpreted the radiology results.

Following the Pilkhana massacre which occurred February 25 and 26 leaving 74 dead and the inferno at the Bashundhara City shopping mall complex March 13 leaving seven dead, Prime Minister Sheikh Hasina said security measures are being tightened countrywide across Bangladesh.

Fire drills will be enacted at all key-point installations (KPI). Fire fighting systems will be examined by the fire brigade and the public works department (PWD) to ensure functionality. Security measures will be enhanced supplementing areas under private security such as at the Bashundhara City Complex.

The Fire Service and Civil Defence Department requires modernization and needs new equipment to fight fires past the sixth floor of buildings. The Fire Brigade says it needs turntable ladders, snorkels, foam-tenders, lighting units, emergency tenders, fireproof uniforms, and rescue ropes for fire fighting and rescue operations. Transportation to fires is also an issue due to narrow roads, low electrical wires and congestion.

The Bangladesh National Building Code requires fire fighting equipment installed in buildings over seven floors. This code is to be monitored by authorities to ensure compliance with the new guidelines and to make sure buildings are being maintained.

The Bashundhara City Complex opened Monday for shoppers two days after Friday’s blaze. A probe is underway to determine the cause of the fire and to assess structural damage.

Loss of life was minimized as the blaze broke out on a Friday, the beginning of the weekend in Bangladesh, so offices in the upper floors were empty. The lower eight floors are used for shopping and the upper floors are all Bashundhara Group offices.

The mall is valued at Tk 7.0 billion (US$100 million). It is not known if the complex is covered by fire insurance.

It is estimated that it will take over two years to rebuild the area damaged by flames which were burned down to a skeleton. Bashundhara City’s technical advisor, Latifur Rahman, estimated damages at Tk 2.0 billion (US$29m).

Only one television cameraman has been allowed in to film the burnt area. None of the 2,500 shops, cinemas or cafes were burnt by the inferno. The seventh and eighth floors still experience smoke damage, and there was water damage to merchandise.

A three member committee is currently investigating the cause of the fire which will consist of Iqbal Khan Chowdhury, joint secretary of the ministry, representatives of the police, IGP Noor Muhammad, and fire brigade, Director General Abu Nayeem Md Shahidullah. The committee is required to report within the week with their findings. The forensics department is also sifting through the burnt remains.

The Dhaka Chamber of Commerce and Industries has also formed a committee which has begun interviewing witnesses and recording their testimony alongside the government committee.

It has been discovered that 150 closed circuit cameras were not being used when the fire started. Another mystery is why the mall fire fighting system has been found unused.

“In the shopping mall there is an ultra-technology elevator which runs even without electricity but we have found that locked,” Iqbal Khan Chowdhury, joint secretary (Police) of the home ministry, said. “Why the fire burnt so fiercely is a matter to think. We have to see if there was any incendiary substance there. These matters seem to be mysterious.”

Mall management has been asked to submit substances and items which would have been in the upper floors when the fire started. The fire erupted on the 17th floor and spread quickly to the two floors above and engulfed the three floors below. The aerial ladders belonging to the Fire Service and Civil Defence reached as high as the 13th floor of the 21-storey building.

Videos have been sent to the United States (US) for examination to assist in determining the cause of the fire and to help in the damage assessment. Experts from the US are expected to arrive soon.

Firefighters were brought to the rooftop of the 20-storey tower by helicopter. The only fatality in this operation was Baki Billa, a firefighter of Bashundhara City firefighting department, who fell when climbing down a rope from a helicopter to the roof of the building. Three other firefighters made the transition safely. At this same time, the chief security officer was safely rescued by the Bangladesh Air Force helicopter, a Bell 212. Six security officers of the complex also lost their lives.

Despite the passage of a 700 billion USD bill by the United States House of Representatives on Friday and the Senate on Wednesday, two U.S. states may need loans totaling over 14 billion dollars.

California and Massachusetts are seeking at least 7 billion dollars each from the federal government as loans. Officials and lawmakers in both states say that the loans would be temporary.

According to Massachusetts’ state treasurer, Timothy P. Cahill, the state was unable to borrow money last week on a short term loan. He also states that the state can afford to pay its bills and debts for the next few weeks, but not beyond that without a short-term loan from the government. Cahill has asked the federal government for a loan similar to the recent one passed by Congress and the Senate.

“That’s all we would ask them to do: Treat us like the investment banks,” said Cahill to the Associated Press.

Officials in California say they need an emergency loan, or they will run out of money by the end of October. California’s governor, Arnold Schwarzenegger said the state is “not out of the woods” and needs a short term loan from the government.

“California and other states may be unable to obtain the necessary level of financing to maintain government operations and may be forced to turn to the federal treasury for short-term financing,” said Schwarzenegger in a letter to the Treasury Department, which is taking the letter under consideration.

On Friday, the U.S. House of Representative voted to pass a revised bailout bill which included raising the FDIC insurance cap to $250,000, a move designed to please progressives. However, the $110 billion in tax breaks, earmarks and what has been called pork barrel spending is not offset by any increases in revenues and has added opposition to the bill from some Representatives in the House. Earmarks added into the bailout bill included $192 million in tax rebates for the Virgin Islands rum industry, $148 million in tax cuts for the wool industry, $100 million tax cuts to the auto racing industry, and $48 million in Hollywood tax incentives, among others.

NASA’s Cassini–Huygens spacecraft has discovered evidence for a large-scale saltwater reservoir beneath the icy crust of Saturn’s moon Enceladus. The data came from the spacecraft’s direct analysis of salt-rich ice grains close to the jets ejected from the moon. The study has been published in this week’s edition of the journal Nature.

Data from Cassini’s cosmic dust analyzer show the grains expelled from fissures, known as tiger stripes, are relatively small and usually low in salt far away from the moon. Closer to the moon’s surface, Cassini found that relatively large grains rich with sodium and potassium dominate the plumes. The salt-rich particles have an “ocean-like” composition and indicate that most, if not all, of the expelled ice and water vapor comes from the evaporation of liquid salt-water. When water freezes, the salt is squeezed out, leaving pure water ice behind.

Cassini’s ultraviolet imaging spectrograph also recently obtained complementary results that support the presence of a subsurface ocean. A team of Cassini researchers led by Candice Hansen of the Planetary Science Institute in Tucson, Arizona, measured gas shooting out of distinct jets originating in the moon’s south polar region at five to eight times the speed of sound, several times faster than previously measured. These observations of distinct jets, from a 2010 flyby, are consistent with results showing a difference in composition of ice grains close to the moon’s surface and those that made it out to the E ring, the outermost ring that gets its material primarily from Enceladean jets. If the plumes emanated from ice, they should have very little salt in them.

“There currently is no plausible way to produce a steady outflow of salt-rich grains from solid ice across all the tiger stripes other than salt water under Enceladus’s icy surface,” said Frank Postberg, a Cassini team scientist at the University of Heidelberg in Germany.

The data suggests a layer of water between the moon’s rocky core and its icy mantle, possibly as deep as about 50 miles (80 kilometers) beneath the surface. As this water washes against the rocks, it dissolves salt compounds and rises through fractures in the overlying ice to form reserves nearer the surface. If the outermost layer cracks open, the decrease in pressure from these reserves to space causes a plume to shoot out. Roughly 400 pounds (200 kilograms) of water vapor is lost every second in the plumes, with smaller amounts being lost as ice grains. The team calculates the water reserves must have large evaporating surfaces, or they would freeze easily and stop the plumes.

“We imagine that between the ice and the ice core there is an ocean of depth and this is somehow connected to the surface reservoir,” added Postberg.

The Cassini mission discovered Enceladus’ water-vapor and ice jets in 2005. In 2009, scientists working with the cosmic dust analyzer examined some sodium salts found in ice grains of Saturn’s E ring but the link to subsurface salt water was not definitive. The new paper analyzes three Enceladus flybys in 2008 and 2009 with the same instrument, focusing on the composition of freshly ejected plume grains. In 2008, Cassini discovered a high “density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected” in geysers erupting from the moon. The icy particles hit the detector target at speeds between 15,000 and 39,000 MPH (23,000 and 63,000 KPH), vaporizing instantly. Electrical fields inside the cosmic dust analyzer separated the various constituents of the impact cloud.

“Enceladus has got warmth, water and organic chemicals, some of the essential building blocks needed for life,” said Dennis Matson in 2008, Cassini project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California.

“This finding is a crucial new piece of evidence showing that environmental conditions favorable to the emergence of life can be sustained on icy bodies orbiting gas giant planets,” said Nicolas Altobelli, the European Space Agency’s project scientist for Cassini.

“If there is water in such an unexpected place, it leaves possibility for the rest of the universe,” said Postberg.

United States President Barack Obama stated Monday that insurance giant AIG is in financial trouble due to “recklessness and greed,” and called for legal action to stop the company from giving out millions of dollars in bonuses to its executives.

“It’s hard to understand how derivative traders at AIG warranted any bonuses, much less $165 million in extra pay,” Obama said. “How do they justify this outrage to the taxpayers who are keeping the company afloat.”

Obama’s statement comes after reports surfaced last weekend saying the insurance agency, which is in deep financial trouble, had paid US$165 million to executives in bonuses, after receiving $170 billion as part of a government bailout plan.

AIG has said that the bonuses have to be given out, as the company is legally required by contract to do so. A representative with the National Economic Council, Lawrence H. Summers, also said that the bonuses were required to be given out. If AIG had refused to give out the bonuses, employees could file a lawsuit against the company for the money.

“We cannot attract and retain the best and the brightest talent to lead and staff the A.I.G. businesses — which are now being operated principally on behalf of American taxpayers — if employees believe their compensation is subject to continued and arbitrary adjustment by the U.S. Treasury,” AIG CEO Edward M. Liddy said in a letter addressed to Treasury Secretary Timothy F. Geithner on Saturday.

Liddy said that he asked Geithner “to use that leverage and pursue every legal avenue to block these bonuses and make the American taxpayers whole.”

“I want everybody to be clear that Secretary Geithner’s been on the case,” Obama said. “He’s working to resolve this matter with the new CEO, Edward Liddy, who, by the way, everybody needs to understand, came on board after the contracts that led to these bonuses were agreed to last year.”

If the bonuses cannot be stopped, the U.S. Congress says they want AIG to reimburse the government. Congress is looking to impose stiff new taxes on the pay, or ordering the company to return the money which was originally granted from a government bailout. In a letter to House Speaker Nancy Pelosi on Tuesday, senator Richard Shelby promised that the treasury will recover all of the money. Several U.S. senators along with Liddy have sent letters to AIG asking for the bonuses to be renegotiated, something AIG agreed to and says they will reduce future bonuses by 30%. Senators state that if Libby does not respond by renegotiating the bonuses, the Senate Finance Committee will propose an excise tax. Not only will an excise tax be proposed on AIG, but all companies receiving bailout money and their employees who receive bonuses.

Numerous House Democrats have introduced legislation which would place a 100% tax on any bonuses of over $100,000 from companies that are receiving government bailout funds. Meanwhile in the Senate, a bipartisan proposal by Max Baucus (D-Montana) and Charles Grassley (R-Iowa) would levy a special 90% excise tax on AIG’s bonuses. Asked Senator Baucus, who chairs the Senate Finance Committee: “What is the highest excise tax we can impose that will stand up in court? Let’s find out.”
