The last of the line

I mowed the back yard today, but this usually mundane chore was very different, it was the first time in almost 18 years I did not have a German Shepherd or two following behind me.
Chief our wonderful German Shepherd crossed over to the other side Saturday May 29th. A sudden and rapidly growing cancer was discovered in his abdomen. Chief was the last of our SAR dogs, preceded in death by Schatzie and Ajax. A gentle giant Chief who could enter a classroom, church, or just walk up to you and display an affection that surprised most people because of his size (and breed of course). He could speak on command or whenever he felt like talking, the only problem, he knew only one volume, wide open, probably a result of the SAR recall or refind where the search dog barks to let his handler know he has found someone. Chief had to retire early from SAR work because of a heat stroke in 1999. He always loved his people and his collection of stuffed animals. Strange he never ripped or chewed these toys, only carried them around the house and yard. Chief will be missed by many but joined by his old pack in the afterlife. Chief was 13.

My Hero

My hero died yesterday. I think when most people think of their hero or role model they think of a sports star or perhaps a courageous military figure. My hero was (still is) a dog. A brilliant white German Shepherd named Schatzie. 1991 was a great year for me. Back at Ft Bragg from Iraq I rekindled a flame with a high school love. She is Tricia Davis and with her discovered the world of search and rescue dogs (SAR DOGS). Trish and I married and moved to Ft. Benning Georgia in 1992. A year later my brother Tim presented me baby Schatzie as a Christmas gift. My still growing fascination for search and rescue received a serendipitous discovery. A SAR Dog team leader, Sandy Crain, was living where we would soon call home near Ft. Benning. Sandy was the leader of Georgia K-9 a renowned SAR Dog unit with working ties to the FBI, Georgia Bureau of Investigation (GBI) and others in need of search dogs. We asked Sandy for a chance to join the team, passed the requisite screening and started our life as a SAR dog team. We worked countless hours learning the intense profession. Days turned into years and Schatzie became a proficient SAR Dog. To enhance my value to the SAR team I enrolled in the Georgia EMT-I program. While in this program I learned about Emergency Management and preparedness.

Why my hero? I am writing this from Atlanta, here attending the 2010 US Public Health Preparedness Summit as the Director of a regional emergency preparedness office in based Columbia SC, a significant and vital public office. I would not be writing this tribute if not for the chance destiny resulting from my human-canine interface with Schatzie. The result of this human/canine relationship is who I am today. I would not have pursued my life as a public servant if not for this chance bond.
A hero can be that being that leads you down a righteous path you did not expect. Schatzie and I walked many miles of paths over all types of terrain. This path presented me the opportunity to realize my professional goal. When our daughter Delaney was born in 2002 search and rescue became a minor interest in my life. Yes Schatzie was still a geared up dog with many years left but we choose to retire from search and rescue. She lived out her many remaining years surrounded by the family she loved and by me the person who found his way through her. I miss her of course but I know a tireless four legged white angel is always waiting and ready.

HEAVEN SCENT

TRAINED DOG TEAMS GIVE NEW MEANING TO SEARCH AND RESCUE

THEY'RE TRYING TO STAY ON TOP OF THEIR GAME FOR ``REAL THING''

``10-41,'' Roger Hovis says into his radio, indicating he's beginning his search.

This time it's practice, but Hovis, an Air Force sergeant assigned to the Army Rangers, performs real searches with the Georgia K-9 Rescue Association Inc., a Columbus-based volunteer unit.

Hovis and his dog are among eight pairs of dogs and owners in the Columbus area who have met national standards to perform searches.

``There's no better thrill than a real rescue,'' said Rod Gilchrist of Albany, working recently with his dog ``Blue'' in a wooded area of Chattahoochee County, near Cusseta.

The dogs seem to share their handlers' passion.

``King would die trying to find somebody,'' said Columbus firefighter and team member Scott Boatner, recalling the day his German shepherd was bitten by a snake during a search.

``I don't look at my dog as just a dog,'' Boatner said.

The dogs sometimes act like humans.

Once, when King and Boatner found the body of a dead person, King refused to take his customary treat and wouldn't play with his favorite toy.

``He just laid with his head in my lap all the way home,'' Boatner said.

On a hot August training day recently, starting at 8 a.m., team members gathered for their search and discussed a recent mission before they began their exercises.

Days earlier, two members of the rescue group had been to Lake Martin in Tallapoosa County to help Alabama Marine Police search for two drowning victims. The victims were not found while they were there.

Last month, team members traveled to Randolph County, Georgia, where they found an 86-year-old woman with Alzheimer's disease who had wandered away from home. It was the fourth Alzheimer's sufferer Georgia K-9 had found this year.

Tricia Hovis described the ``find'' this way: ``I was there a few weeks ago when our unit found an elderly lady who lay deep in the woods on a bed of twigs at 2 a.m. in the pouring rain. Visiting her in the hospital the following day was one of the greatest feelings I've ever had.''

When the training begins, Roger Hovis and his white German shepherd, ``Schatzie,'' are dropped off and told to search 200 meters into a heavily wooded area for a volunteer decoy.

Hovis checks his map and tosses baby powder into the air to determine the wind direction.

``Find 'em. Find the person,'' Hovis tells Schatzie, and she takes off, sniffing the air.

Handlers and dogs work a designated area, going back and forth in a zig-zag pattern.

Humans give off a scent, which is carried by air or water currents.

After searching the air for the ``scent cone,'' the dog moves in to the source. When he makes the find, the dog returns to his handler and leads him back to the victim.

``No, leave it!'' Hovis shouts, when Schatzie takes off after a rabbit.

The dog returns, and the search continues.

HOW DO THEY DO IT?

Dogs have long been used to help humans with more than just searching.

They're also used to help people with disabilities, ranging from blindness to mental illness.

Law enforcement agencies use dogs to detect drugs, bombs, evidence of flammable liquids at fire scenes, money and criminal suspects -- as well as victims.

There's even a ``beagle brigade'' in Florida to keep insect-infected agricultural products from being brought illegally into the country.

There are different techniques to train dogs to search.

Columbus volunteers use a method called air-scenting.

While bloodhounds use a scent article to track a particular person, air-scenting dogs are trained to follow human scent through the air to its strongest point.

In order to follow the dogs, a handler must be able to use a compass, read a topographical map, detect wind direction, provide first aid, and travel rough terrain or ride in a boat for at least three eight-hour days in all light and weather conditions.

Researchers worldwide -- and as near as Auburn University -- have studied how dogs detect different scents.

An Auburn University group called the Institute for Biological Detection Systems, conducts research into how dogs detect various chemical elements, how they distinguish them from one another and how they retain that ability.

Scientists don't completely understand how dogs can discriminate a human scent from other background odors, said Larry Myers, an associate professor of physiology at Auburn and a national authority on dogs' behavior and sensory abilities.

Dogs primarily rely on smell, but they also have acute vision and hearing, Myers said.

``Basically, dogs are lazy, just like people. They'll select the easiest way to get the job done,'' he said.

Dogs can also apparently discriminate between grades of odor so they can identify where the odor is strongest, Myers said.

While Myers encourages wide use of dogs for detecting human and other scents, he stresses that ongoing training is key. Using untrained dogs or letting their training lapse is counterproductive, he said.

``They (volunteer groups) are probably under-utilized,'' Myers said.

``Once there has been a reasonable assessment that a major search is under way, they need to be called and consulted, at least,'' said Myers.

WHY HUMANS DO IT

Volunteers provide their own dogs and gear and pay their own expenses during search operations.
Sometimes law enforcement agencies provide mileage reimbursement.

There are more than 200 known Search and Rescue Dog organizations in the United States, according to the National Association For Search and Rescue Inc., which sets standards for dogs and handlers.

The Columbus-based unit was founded in 1985 and is a member of the National Association for Search and Rescue and the Georgia Regional Search and Rescue Team.

The unit usually responds to calls throughout Georgia, Alabama, Florida and the Carolinas, but longtime member June Vigrass and two other members assisted with a search on a remote Costa Rican island, where they were brought in by military helicopter.

The search was for an American ``adventure'' tourist who apparently got lost mountain climbing, Vigrass said. To her knowledge, the woman was never found.

Her 9-year-old dog, ``Caleb,'' has participated in more than 100 searches, but he made his first live rescue this year, said Vigrass, who is also a paramedic for Marion County.

Like Vigrass and Boatner, many volunteers have jobs related to search and rescue work.

Unit members include retired military personnel (Joe Lambert, Wesley Basey), an investigator with the Randolph County Sheriff's Office (Hoyt Lumpkin) and an assistant Emergency Medical Services chief (Robert Futrell).

But other members come from all trades and walks of life.

Its president and longtime member Sandy Crain is a Chattahoochee County elementary art teacher. Others are in business, like Cason Callaway III, Curtis Flatt of Masback, Kathy Terry of Oneida, Brigitte Basey of GNB Batteries, and Kim Moulton, a communications student.

Most dogs are German shepherds, but others include a Labrador retriever and Callaway's Greater Swiss mountain dog, ``Rhett Butler.''

Dogs are obedience-trained. The dog and handler must understand each other's commands and signals.

When the dog finds a person, he returns and ``alerts'' the handler by speaking (barking) or another sign.

In a water search, the dog dips his head into the water or scratches the boat bottom to signal a human scent.

Although unit members love finding people, they also help law enforcement investigators by searching and ruling out an area.

If they can say where the person is not, they've helped.

The group's credo is to ``save lives and reduce human suffering,'' says Roger Hovis, adding, ``I am an advocate for the victim, and I can tell in rural Georgia people have appreciated our help.''

Crain, the president and training officer, is a charter member. Members draw on her 13 years experience and that of other longtime handlers.

Hovis, who travels extensively with his job, missed several practices with Schatzie and says that contributed to her taking almost two hours to find her decoy and becoming distracted.

But, she found team member Kathy Terry and was rewarded.

``10-42,'' Hovis said into his radio, indicating his search had ended.


The Nose Knows

Skillful trainers teach dogs to sniff out narcotics -- marijuana, cocaine, heroin, methamphetamines, LSD -- termites, gypsy moths, mold in lumberyards, chemicals like gasoline used to start fires, guns, explosives, contraband food, snakes, money being smuggled out of the United States in quantities exceeding the $10,000 limit, cows going into estrus and leaks in underground gas pipelines.

The average dog has 220 million scent receptors, compared with our 5 million.

Debates rage over what a dog smells when it tracks a person, with the most accepted current hypothesis being ``skin rafts,'' tiny particles of bacteria-laden dead skin that are constantly shed.

CDC keeps N-95 recommendation in H1N1 health worker guidance

Lisa Schnirring * Staff Writer

Oct 14, 2009 (CIDRAP News) – The US Centers for Disease Control and Prevention (CDC) today issued eagerly awaited recommendations on pandemic H1N1 infection control in healthcare settings, which affirms its earlier guidance on N-95 respirators but spells out other options for when the respirators are in short supply.

New features in the 17-page report include criteria for identifying suspected influenza patients, suggested isolation periods, methods for balancing isolation precautions, and a more detailed hierarchy for prevention controls.

On Sep 3 the Institute of Medicine (IOM) affirmed the CDC's original guidance that healthcare workers caring for H1N1 patients wear fit-tested N-95 respirators, not surgical masks, as protection against the virus. The IOM report also called for more research on flu transmission and the efficacy of different respiratory protection methods.

Today's CDC guidance came with a caveat that the recommendations will be updated if new information becomes available.

N-95 use in pandemic H1N1 settings has been somewhat controversial; some professional groups oppose routine use of N-95s in flu settings because research on their efficacy has been inconclusive, and many workers find them uncomfortable to wear for long periods.

Recent research has not exactly settled the score. One unpublished study conducted at a hospital in Beijing found that N-95 respirators greatly outperformed surgical masks in protecting workers from flu viruses.

Another study published earlier this month in the Journal of the American Medical Association showed mask protection as rivaling that of N-95s. Some experts, though, have pointed to shortcomings of that study, such as a lack of a control group to account for health workers becoming infected outside the workplace

Hierarchy of preventive steps
In today's guidance the CDC advised facilities to use a hierarchy of controls to prevent flu transmission, starting with eliminating potential exposures such as postponing elective visits by patients who have influenza-like symptoms.

Engineering controls were next, which might involve installing partitions in triage areas or other public spaces. Administrative controls included employee vaccination and enforcing rules about working when sick and implementing respiratory or cough hygiene strategies.

Personal protective equipment (PPE) was ranked lowest on the hierarchy list, because it is the last line of defense when other measures can't be controlled.

The CDC emphasized that focusing on the three other prevention levels could reduce the reliance on PPE. "This is an especially important consideration during the current year, when shortages of respirators have already been reported by many healthcare facilities," the guidance states.

Specifics on N-95s, isolation
The CDC based its N-95 recommendation on several factors, including low levels of population immunity to the new virus, the rise of virus activity before the vaccine is available, and the increased risk of complications in some healthcare personnel, such as pregnant women.

Given that the respirators are likely to be in short supply, the CDC recommends reserving them for situations when protection is most important, such as during aerosol-generating procedures.

When shortages exist, the CDC urges facilities to consider prioritizing respirator use, keeping in mind workers' intensity and duration of exposure, personal risk factors for complications, and vaccination status. Workers who don't receive N-95s should receive surgical masks.

Because patients with more severe illnesses are likely to shed the virus longer than those with milder infections, the CDC recommends a longer isolation period for hospitalized patients.

It says isolation precautions for those with flu symptoms should continue for 7 days after illness onset or 24 hours after fever and respiratory symptoms subside, whichever is longer. Longer periods may be needed for certain patients, such as those with severe immune system compromise or those who may be shedding antiviral-resistant viruses.

Some opposing views
Today's release of the CDC guidelines drew a mixed reaction from the Society for Healthcare Epidemiology of America (SHEA).

Though SHEA praised the CDC's call for a multipronged approach for preventing flu transmission in healthcare settings, it knocked the N-95 respirator recommendation. SHEA said in a press release that it had urged the CDC, based on clinical and scientific evidence, to replace its N-95 recommendation with surgical masks for routine care of flu patients.

Mark Rupp, MD, president of SHEA and an infectious disease specialist at the University of Nebraska Medical Center, said in the statement that N-95s aren't necessary or practical for protecting healthcare workers and their patients against the H1N1 virus. "The best science available leaves no doubt that the best way to protect people is by vaccinating them," he said.

When the IOM issued its report last month, the Association of Professionals in Infection Control and Epidemiology (APIC) also criticized the recommendation to wear N-95s, saying that the guidance fails to take into account many practical and logistical problems linked to their use, such as discomfort, costs, shortages, and the difficulty of fit testing.

The World Health Organization recommends only standard and droplet precautions for healthcare workers who have routine contact with flu patients. Canada recently called for N-95 use only during aerosol-generating procedures.

SHEA suspects that the CDC was pressured by labor unions to recommend N-95 respirators, despite evidence that they don't offer any extra protection in droplet transmission diseases such as pandemic H1N1.

Continuing to recommend N-95s for routine care of flu patients might have unintended consequences, Rupp said in the statement. "We could actually put healthcare workers at greater risk by further reducing an already short supply of a device that is needed for high-risk procedures such as bronchoscopy by using it for routine care."

He said the N-95 debate has distracted hospitals and clinics from attention toward investing in other measures for controlling the spread of the virus, such as rigorous application of basic infection control tactics and rapid identification and separation of patients who have the virus.

"We understand the role of the CDC in providing reassurance during a period of evolving evidence, and we urge the CDC to continue to revisit its recommendations as new data becomes available," Rupp said.
