News.com.au From correspondents in Hong Kong March 31, 2003

HONG KONG took drastic new measures today to combat a killer pneumonia as nearly 100 more cases were reported in the territory amid growing disruption to travel and business across Asia. The increasingly fraught battle to contain Severe Acute Respiratory Syndrome came as the US authorities warned the virus could be more contagious than first thought and advised against travel to parts of Asia.

The mysterious illness has now infected more than 1600 people in 15 countries and killed at least 59 people.

It erupted in southern China, spread to Hong Kong and has been taken worldwide by airline passengers.

The Hong Kong authorities today isolated an entire housing block for 10 days in an attempt to control the epidemic after 213 people on the estate were found to be infected - a rise of 92 overnight.

INTERNATIONAL health experts expect to identify within days the virus causing the mysterious, flu-like disease that is spreading fast in parts of Asia, although finding a specific treatment may take more time, a UN health official said.

"I think we can identify the causative agent in quite a short time period. We think probably within a few days, at most a few weeks," said Hitoshi Oshitani, the World Health Organisation coordinator for severe acute respiratory syndrome, or SARS.

"But this doesn't mean we will find the specific treatment for this disease within the short time period," he told a news conference.

Researchers suspect the disease - which Oshitani called "the most significant outbreak that has been spread through air travel in history" - was caused by the paramyxovirus or the coronavirus.

Oshitani said the virus causing the new disease apparently came from an animal.

America has been told that there are sufficient doses (300 million) of an effective vaccine to render all of the U.S. population protected from a smallpox attack.by Saul B. Wilen, M.D.

San Antonio - Mar 28, 2003

One would think, after the many months of debate and evaluation by the experts, that all of the major concerns about the United States smallpox protection plan presently being implemented, would have been resolved. However, at last count seven weeks into stage one (of three stages), only about 17,000 individuals (3.7 percent of the goal) have been vaccinated.

Stage one was expected to complete the vaccination goal of 450,000 hospital healthcare workers in four weeks. However, there has been widespread refusal by hospitals and individuals to participate. Do the remaining 433,000 healthcare workers who have chosen not to participate know something that the experts do not know? At this rate of 5000 vaccinated per week it could take up to 86 weeks, or 1.7 years, just to complete stage one.

America has been told that there are sufficient doses (300 million) of an effective vaccine to render all of the U.S. population protected from a smallpox attack. With this stockpile of available vaccine in place and stage one of the protection program floundering, it has been suggested that moving on to stage two, the vaccination of first responders (police, firefighters and emergency management personnel) might in some way compensate for the shortfall. Participation estimates for this target group is also expected to be disappointingly low.

Additionally, stage two vaccinations will not produce the smallpox-protected teams of healthcare workers necessary for vaccinating the general public as planned for in stage three. The remaining 289 million Americans are slated for vaccination within four days of a confirmed smallpox outbreak.

Is this possible, and at what price? Such a feat has never been previously attempted. Will mass panic be the result? Can such an approach allow for the proper, methodical screening of the general population for potential contraindications (reasons why the vaccine should not be given) so that life-threatening complications are reduced, not increased?

Smallpox is one of the most dangerous biological weapons of mass-destruction available to terrorists. It is a contagious viral disease with no known treatment once an individual is infected. Thirty percent of those who become infected with smallpox (3 out of every 10) will die. The United States population is unprotected.

Smallpox killed hundreds of millions of people around the world before being declared eradicated in 1980. Early smallpox symptoms are flu-like in nature. Those who are not protected against smallpox and become infected during a bio-terror attack using smallpox, pose a clear and present danger to their families, their communities, and the nation. The commitment must be prevention as the key to survival for the welfare of the American people and in support of winning the war on terrorism.

However, there are life-threatening complications and deaths related to the vaccine, which includes a live virus that can infect the body. This represents a risk that equates to approximately 300 to 600 deaths (l in 500,000) included in up to 10,500 complications possible for the total population of 300 million.

The universal vaccination of the U.S. population would be a prevention strategy, rendering the use of smallpox as a bio-terrorism weapon essentially meaningless. Vaccination properly performed will protect individuals from infection. Protection can result from a systematic, methodical, and progressive program of universal (everyone who can be vaccinated safely) smallpox vaccination of Americans. This is one of the very few opportunities available to remove a bio-terror agent from being used by America's enemies.

Universal vaccination has been resisted based on concerns relating to potential complications of the vaccine. A major stumbling block has also been doubts about the certainty as to whether the threat of a bio-terrorism attack using smallpox as the agent, justifies the risk. Many hospitals have rejected participation due to concerns about vaccinated workers accidentally spreading the live virus in the vaccine to patients susceptible to complications.

Compensation for those injured by vaccination has been an issue raised by medical and healthcare workers when they refused participation in the vaccination program.

A compensation proposal of $262,100 for each person who dies or is permanently and totally disabled by the vaccine has been proposed. Another factor has been virtually non-existent education programs for the public in general, ineffective education programs for medical professionals, healthcare workers, and first responders, and contradictory information that has been released by government officials on all levels.

Many opponents, especially physicians and other healthcare professionals, of a universal program for smallpox vaccination starting as soon as possible for all Americans without contraindications, are now rethinking this position.

In the editorial by Dr. John Clough in the February 2003 issue of the Cleveland Clinic Journal of Medicine he agonizes through the alternatives and comes to the conclusion, "The choices are not pretty or easy. And perhaps it comes down to the nasty conclusion that we really don't have any choice. We may have to provide whatever protection we can for the population."

A recently related concern has been the outbreak of a respiratory illness with associated pneumonia now having resulted in deaths, which seems to have begun in China as early as January 2003. As it spreads it is becoming a serious world public health problem. It is not considered to be terrorist related.

The illness called SARS (severe acute respiratory syndrome) begins with flu-like symptoms. For the first three weeks of March 2003 the World Health Organization (WHO) working with the other major public health organizations and laboratories has been trying to identify the cause.

This demonstrates that even in the hands of the best available public health organizations and laboratories identification has at best been difficult and delays can and do occur. Such a delay in responding to a bio-terror agent changes the response assumptions and the preparedness to react.

In applying this scenario, flaws in expert thinking process used in the design of the smallpox vaccine protection program become apparent, especially in relation to stage three.

The use of smallpox virus by terrorists is a consideration since the virus is contagious, has no treatment, has a high death rate, is easily transported, and can be readily disseminated to an unprotected population.

Just as in the anthrax experience in 2001 where finely milled spores with a high potential for causing death were used, the smallpox virus could be genetically altered. Changes are possible in the incubation period for the disease (the length of time before the disease symptoms appear) and changes in the duration of the early flu-like symptoms therefore, making it more difficult to diagnose infection.

Elements that make identification more difficult cause the assumed time frames such as a four day window in which to vaccinate the American population to be unrealistic.

America is not presently prepared for a bio-terrorism attack, especially not for the use of smallpox as the bio-terror agent. There is a better way than the program presently in place.

A universal smallpox vaccination program instituted now and progressively implemented with enough time to adequately screen out those with contraindications will protect the vast majority of the American population and simultaneously minimize the complications and deaths due to the vaccine. Using a universal protection program, prevention is established against a terrorism attack using smallpox as the bio-terror agent.

Jewish World Review March 10, 2003 / 6 Adar II, 5763 By Robert A. Wascher, M.D., F.A.C.S. jewishworldreview.com www.NewsAndOpinion.com |

SARS (Severe Acute Respiratory Syndrome) is a viral infection that has recently become a source of concern among public health officials. First identified in Vietnam, cases of SARS have now appeared in China (in Hong Kong and Guangdong province, in particular), Singapore, Indonesia, Canada, Thailand, the Phillipines, and the United States. Approximately another dozen countries have reported possible cases of SARS within the past several days. At the present time, nearly 1600 cases SARS, including 54 deaths, have been reported throughout the world by the WHO and CDC. Although the causative agent of SARS is not fully understood at this time, it appears to be a previously unknown member of the coronavirus family of viruses. Sadly, the Italian physician who first identified SARS in a German businessman under his care in Vietnam has, himself, now died of the disease.

According to the US Centers for Disease Control (CDC) and the World Health Organization (WHO), the symptoms of SARS include high fever, sore throat, dry cough, shortness of breath, and decreased white blood cell and platelet counts. Other typical symptoms of viral infection may occur with SARS, including headache, muscular pain and stiffness, loss of appetite, malaise, confusion, rashes and diarrhea. The incubation period for SARS appears to be relatively short, ranging from 2 to 7 days following initial exposure. Based upon the rather high prevalence of infections among healthcare personnel, the WHO has indicated that close and sustained contact with infected persons may be necessary to spread SARS. In particular, contact with respiratory droplets from coughs and sneezes, as well as direct contact with bodily secretions, are thought to be important infection vectors. However, recent reports of SARS spread among tenants within apartment buildings in China, and at least one case involving a flight attendant on a Hong Kong-based airline, suggest that the SARS virus may be passed with more casual contact.

The treatment of patients infected with the SARS virus is similar to that recommended for other serious viral respiratory infections, as there are no antibiotics that have any activity against such diseases. The current recommendation is that patients with SARS should be kept in respiratory isolation wards. Supplemental oxygen, inhaled medications to keep the airways clear of secretions and to prevent collapse of small airways, control of excessive fever, intravenous fluids to support blood pressure and vital organs, and, in some cases, mechanical ventilation, are mainstays of supportive treatment.

At the present time, public health officials are not advising prospective travelers to cancel their trips overseas. However, some officials are now suggesting that travel to endemic areas be deferred if possible. Some flight attendants and travelers have taken to wearing surgical face masks in an effort to reduce the risk of inhaling respiratory aerosols from potentially infected persons, although the efficacy of this strategy is uncertain at this time. If you-or anyone you know-has recently developed a severe upper respiratory infection, particularly following travel to one of the countries mentioned above, then medical care should be urgently sought. While there are hundreds of other viruses that can cause the same symptoms as SARS, the virulence of the virus causing SARS seems to approach, at least in some cases, that of strains of influenza that have caused pandemics of severe illness and death in the past.

UPDATE ON SMALLPOX VACCINE

The CDC announced, on March 25th, an advisory regarding the administration of the smallpox vaccine to people with a history of heart disease. More than 30,000 healthcare workers have recently received the smallpox vaccine as part of recent Homeland Defense initiatives. Among these volunteers, seven have developed cardiac-related complications, although it is presently unknown if these complications are directly related to the vaccine. Among these seven stricken healthcare workers, three have experienced heart attacks (one of which was fatal), two cases of angina (chest pain due to blocked coronary arteries) occurred, and two cases of myopericarditis (inflammation of the heart muscle or the fibrous sac that surrounds the heart) occurred. The CDC is currently studying the medical histories of each of these seven patients, and is carefully evaluating their cardiac disease risk profiles (at least one of these patients was reported to have had an extensive history of preexisting heart disease). While cases of heart inflammation were reported during the period when smallpox vaccine was most extensively administered (in the 1960s and 1970s), no epidemiologic studies were carried out at the time in order to ascertain any causative effect by the vaccine.

As it is currently unclear whether or not the smallpox vaccine, which consists of a live virus that is related to the smallpox virus, is linked to these few cases of cardiac complications, the CDC is being somewhat circumspect in its advisory. The CDC is now recommending that persons with a history of cardiomyopathy, heart attack or angina, or any other evidence of heart disease be temporarily deferred from receiving the smallpox vaccine.

INFLAMMATORY MARKERS & RISK OF HEART FAILURE

There is growing evidence that the progression of coronary artery disease is influenced by mediators of inflammation. Most recently, C-reactive protein has taken center stage as a key inflammatory protein that appears to play a critical role in the development of coronary atherosclerosis. While coronary artery disease has been linked with inflammation and, in turn, directly with the risk of developing a heart attack, another equally life-threatening cardiac ailment has not previously been associated with inflammation. Congestive heart failure (CHF), which most commonly occurs after a heart attack permanently damages heart muscle, is a common cause of disability and death among older Americans. As its name implies, CHF results when the heart becomes sufficiently damaged so that its ability to pump blood to the body becomes seriously impaired. Patients with CHF may have difficulty breathing due to fluid build-up in their lungs, and often experience debilitating weakness and fatigue as a result of inadequate oxygen delivery throughout their bodies. Swelling of the lower extremities may also cause difficulties for patients with CHF.

A new study in the journal Circulation looks at the potential role of inflammation in patients with CHF who have never had a heart attack before. This study was conducted within the framework of the highly respected Framingham Heart Study, one of the longest running and largest heart study research programs ever undertaken. In this new study, a total of 732 elderly patients who entered the Framingham Heart Study without any prior evidence of CHF or heart attack were followed for an average of 5.2 years. All study volunteers underwent extensive blood tests upon entry into the study, which included assays for known mediators of inflammation, including C-reactive protein, interleukin-6, and tumor necrosis factor-alpha. Among the 732 volunteers, 56 of them subsequently developed CHF-without experiencing any heart attacks-during the course of this study. The study determined that initially elevated levels of any of these inflammatory mediators were significantly correlated with the subsequent development of CHF among the study volunteers. Among patients who had elevations in the blood levels of all three of these markers upon entering the study, the risk of subsequently developing CHF was more than four time higher when compared to other study volunteers without elevated levels of these inflammatory markers. The study's authors concluded that a single measurement of inflammatory markers in the blood was highly predictive of the risk for subsequently developing CHF, even in the absence of heart attacks.

BREAST FIBROADENOMAS & THE RISK OF BREAST CANCER

The presence of benign fibrous nodules in the breast, called fibroadenomas, has been linked, in some studies, to a slightly increased risk of developing breast cancer. Other benign breast conditions, including ductal hyperplasia, and even a history of prior breast biopsies for benign lesions, have been statistically associated with small increases in breast cancer risk as well.

A new study in the Archives of Surgery looked at 32 patients with fibroadenomas occurring in the breast at the same time as breast cancer. These patients were compared with 26 control patients who had breast fibroadenomas without the concomitant presence of breast cancer in the same breast. The researchers used several highly sensitive tests to assess both the fibroadenoma tumors and the breast cancer tumors for characteristic genetic mutations associated the development of cancer. The study determined that fibroadenomas of the breast, whether or not they co-existed with breast cancers in the same patient, did not contain any of the genetic mutations commonly identified in the breast cancer tumors. From these results, the authors infer that fibroadenomas are not directly associated with the development of breast cancers. This small study should be repeated with larger numbers of patients to validate its findings. However, these results should provide considerable reassurance to women with benign fibroadenomas of the breast.

The World Health Organisation (WHO) has advised against travel to Hong Kong or parts of China due to the outbreak of a deadly, pneumonia-like virus.

The warning came after Chinese authorities said nine more people died from Severe Acute Respiratory Syndrome (Sars) in the Guangdong province last month, bringing the worldwide death toll to 75.

The virus has killed 16 people and infected over 680 in Hong Kong alone.

More than 1,800 people have been infected worldwide, causing widespread fear and the imposition of emergency measures.
