Brisbane hospital workers feared mad cow

Brisbane hospital workers feared mad cow

BRAIN BUG WORRY: Hospital staff feared exposure to Mad Cow Disease after a patient was admitted suffering the human form CJD.

Source: The Daily Telegraph

HEALTH workers at a Brisbane hospital feared being exposed to mad cow disease after a woman was admitted with Creutzfeldt-Jakob disease (CJD) earlier this month. There has never been a case of ''mad cow'' (or variant CJD) in Australia and it has been ruled out in this case because the woman is not showing typical symptoms.

However, CJD - of which there are three types and all are fatal - is also a notifiable disease, and Queensland Health was only advised of the case on Thursday after The Sunday Mail contacted the private hospital to inquire about the woman's condition.

The woman, in her early 60s, has been a patient at the Holy Spirit Hospital on Brisbane's northside for more than 10 days.

A Queensland Health spokesman said that correct infection protocol would be followed.

The woman returned after only a week holidaying in France with her husband when her condition deteriorated.

Mad cow disease may have killed Aussie Aussie pies in mad cow disease risk .End of sidebar. Return to start of sidebar. Her husband - a Brisbane solicitor - said he did not believe his wife had contracted the disease while in Europe, because she was showing signs of illness before they departed.

''All evidence is she had it before we left and started to deteriorate while overseas, so we came back,'' the distraught husband said.

CJD is a rare, degenerative disease of the brain. About 25 people die each year in Australia from the condition.

Variant CJD, which emerged in Britain in the 1990s and is known as ''mad cow'' because it has been linked to eating contaminated beef, is easily distinguishable because of its symptoms.

The husband said there had been some ''difficulty'' at the hospital with acquiring tests and information.

CJD is not contagious but some medical procedures performed on people with CJD have resulted in the disease being transmitted to other people.

Stronger federal health guidelines have been established for the use of organ transplants and for the sterilisation of surgical equipment to reduce the risk of CJD acquired through organ donation or through surgical equipment.

Suzanne Solvyns, from the CJD Support Network Group, visited the hospital last week to assist the family.

''I went to the hospital to help provide them with the correct information,'' she said. ''There is a lot of misinformation out there and medics don't know a lot about it.''

Ms Solvyns said CJD patients were often ''badly'' discriminated against.

''People assume that it is mad cow disease but there has never been a case (in Australia),'' she said.

''I did a presentation on CJD to staff - it had to be explained it was transmissible, not contagious.''

A spokeswoman from the Holy Spirit Hospital said the case was ''a private matter''. ''Be assured if any patients had the disease the hospital would take appropriate measures,'' she said.

The hospital declined to discuss the matter further.

REGARDLESS the source of this CJD/TSE in this case, the potential ramifications from this incident is real, and they are the same as if it was a case of nvCJD. Death from friendly fire and or the pass it forward mode of transmissions. There are many proven modes of transmission via iCJD, and all iCJD is, is sporadic CJD until route and source of the TSE agent has been established. The threat is the same. ...TSS

2.65 At its hearing on 14 May 2010, the committee heard evidence from Dr Alan Fahey who has recently submitted a thesis on the clinical neuropsychiatric, epidemiological and diagnostic features of Creutzfeldt-Jakob disease.48 Dr Fahey told the committee of his concerns regarding the lengthy incubation period for transmissible spongiform encephalopathies, the inadequacy of current tests and the limited nature of our current understanding of this group of diseases.49

2.66 Dr Fahey also told the committee that in the last two years a link has been established between forms of atypical CJD and atypical BSE. Dr Fahey said that: They now believe that those atypical BSEs overseas are in fact causing sporadic Creutzfeldt-Jakob disease. They were not sure if it was due to mad sheep disease or a different form. If you look in the textbooks it looks like this is just arising by itself. But in my research I have a summary of a document which states that there has never been any proof that sporadic Creutzfeldt-Jakob disease has arisen de novo—has arisen of itself. There is no proof of that. The recent research is that in fact it is due to atypical forms of mad cow disease which have been found across Europe, have been found in America and have been found in Asia. These atypical forms of mad cow disease typically have even longer incubation periods than the classical mad cow disease.50

Surveillance of Creutzfeldt-Jakob disease in Australia: 2010 update

Genevieve M Klug, Alison Boyd, Amelia McGlade, Christiane Stehmann, Colin L Masters, Steven J Collins

Abstract

Surveillance of all human prion diseases in Australia has been the responsibility of the Australian National Creutzfeldt-Jakob Disease Registry (ANCJDR) on behalf of the Australian Government Department of Health and Ageing since the Registry’s inception in October 1993. The ANCJDR was established in response to the identification of 4 CJD deaths in recipients of human-derived pituitary hormone. The initial brief was to perform focused surveillance for any further iatrogenic cases of CJD; however the scope of surveillance was soon expanded to include all cases of CJD occurring in Australia both prospectively and retrospectively to 1970. The activities of the ANCJDR have evolved from: routine surveillance responsibilities to detailed epidemiological analysis at both national and international levels; expert advice in relation to, and management of, infection control issues; and the provision of a number of tests to aid the diagnosis and classification of CJD in suspect cases. In this brief report, surveillance outcomes are examined with the inclusion of figures from the reporting period of 1 April 2009 to 31 March 2010 and the diagnostic services offered by the ANCJDR are outlined to provide a greater insight into this aspect of the Registry. Commun Dis Intell 2010;34(2):96–101.

Keywords: Australian National Creutzfeldt-Jakob Disease Registry, CJD, human-derived pituitary hormone treatment, transmissible spongiform encephalopathies

snip...

The majority of Australian CJD cases have been classified as sporadic CJD (90.4%), whilst the remainder are familial (8.3%) and iatrogenic (1.3%) cases. Since the last reporting period, 20 new sporadic cases have been classified (16 definite, 4 probable) and 2 definite, familial cases. No cases of vCJD or further cases of iatrogenic cases have been identified. The inclusion of the 22 newly classified cases has not markedly altered the median illness duration or age at death of the 3 CJD aetiologies compared with previous reports. The median age at death occurs at 67 years in sporadic cases (males 66 years, females 67 years), 59 years in familial cases (males 51 years, females 62 years) and 42 years in iatrogenic cases (males 46.5 years, females 39 years). The median duration of illness is 4 months in sporadic cases (males 3 months, females 4 months), 6 months for familial cases (males 4.5 months, females 8 months) and 6.5 months for iatrogenic cases (males 2.5 months, females 9.5 months). Only 8% of all definite and probable CJD deaths occur under the age of 50 years and a third of these are attributable to iatrogenic or genetic CJD. The remaining cases have been investigated closely for the possibility of all forms of CJD including vCJD and after detailed follow-up, have been classified as sporadic cases.

[9.03 am]

BELLINGER, Mr Brad, Chairman, Australian Beef Association

CARTER, Mr John Edward, Director, Australian Beef Association

CHAIR—Welcome. Would you like to make an opening statement?

Mr Bellinger—Thank you. The ABA stands by its submission, which we made on 14 December last year, that the decision made by the government to allow the importation of beef from BSE affected countries is politically based, not science based. During this hearing we will bring forward compelling new evidence to back up this statement. When I returned to my property after the December hearing I received a note from an American citizen. I will read a small excerpt from the mail he sent me in order to reinforce the dangers of allowing the importation of beef from BSE affected countries. I have done a number of press releases on this topic, and this fellow has obviously picked my details up from the internet. His name is Terry Singeltary and he is from Bacliff, Texas. He states, and rightfully so:

You should be worried. Please let me explain. I’ve kept up with the mad cow saga for 12 years today, on December 14th 1997, some four months post voluntary and partial mad cow feed ban in the USA, I lost my mother to the Heidenhain variant Creutzfeldt-Jakob disease (CJD). I know this is just another phenotype of the infamous sporadic CJDs. Here in the USA, when USA sheep scrapie was transmitted to USA bovine, the agent was not UK BSE—it was a different strain. So why then would human TSE from USA cattle look like UK CJD from UK BSE? It would not. So this accentuates that the science is inconclusive still on this devastating disease. He goes on to state:

The OIE— the International Organisation of Epizootics, the arm of the WTO— is a failed global agent that in my opinion is bought off via bogus regulations for global trade and industry reps. I have done this all these years for nothing but the truth. I am a consumer, I eat meat, but I do not have to sit idly by and see the ignorance and greed of it all while countless numbers of humans and animals are being exposed to the TSE agents. All the USA is interested in is trade, nothing else matters.

Even Dr Stanley Prusiner, who incidentally won the Nobel Health Prize in 1997 for his work on the prion—he invented the word ‘prion’, or it came from him—states:

The BSC policy was set up for one purpose only, trade—the illegal trading of all strains of TSE globally throughout North America, which is home to CBSC, IBSC and HBSC, many scrapie strains and two strains of CJD to date. (please note typo error, those should have read cBSE, lBSE, and hBSE...tss)

I would also like, while I have the opportunity, to explain the beef-off-the-shelves myth. At the first Senate hearing on 14 December, it was explained that the reason why they allowed BSC beef into Australia was the beef-off-the-shelves policy, whereby if we found a case of BSC in Australia they would have to recall all—

Friday, 5 February 2010 Senate RRA&T 3

RURAL AND REGIONAL AFFAIRS AND TRANSPORT

Senator HEFFERNAN—Which of course is total BS.

Mr Bellinger—Correct. This is written in the FSANZ document—Food Standards Australia New Zealand. Why isn’t this same policy in New Zealand? It is not—it is only in Australia. We are the only country in the world to have this idiotic policy. So we again call for the tabling of the WTO obligations paperwork. We do not believe that exists.

let's take a closer look at this new prionpathy or prionopathy, and then let's look at the g-h-BSEalabama mad cow.

This new prionopathy in humans? the genetic makeup is IDENTICAL to the g-h-BSEalabama mad cow, the only _documented_ mad cow in the world to date like this, ......wait, it get's better. this new prionpathy is killing young and old humans, with LONG DURATION from onset of symptoms to death, and the symptoms are very similar to nvCJD victims, OH, and the plaques are very similar in some cases too, bbbut, it's not related to the g-h-BSEalabama cow, WAIT NOW, it gets even better, the new human prionpathy that they claim is a genetic TSE, has no relation to any gene mutation in that family. daaa, ya think it could be related to that mad cow with the same genetic make-up ??? there were literally tons and tons of banned mad cow protein in Alabama in commerce, and none of it transmitted to cows, and the cows to humans there from ??? r i g h t $$$

ALABAMA MAD COW g-h-BSEalabama

In this study, we identified a novel mutation in the bovine prion protein gene (Prnp), called E211K, of a confirmed BSE positive cow from Alabama, United States of America. This mutation is identical to the E200K pathogenic mutation found in humans with a genetic form of CJD. This finding represents the first report of a confirmed case of BSE with a potential pathogenic mutation within the bovine Prnp gene. We hypothesize that the bovine Prnp E211K mutation most likely has caused BSE in "the approximately 10-year-old cow" carrying the E221K mutation.

Interestingly, when you have cases of cjd increasing yearly, it's supposedly due to better surveillance etc. yet here we see, cjd _decreased_ in 2009, and only a few bumps up and down since 2000, pretty much holding the same, and this is with _better_ surveillance. so, really, the myth that sCJD increases due to better surveillance, is just that, a myth. sporadic cjd and nvCJD increased with countries with BSE, and as the feed ban was put into place and enforcement took hold, BSE cases dropped, along with nvCJD cases and sporadic CJD cases in BSE countries. interesting is it not. However, I wonder how this would play out over the next decade or so, if Australia starts importing products from BSE mad cow Countries ??? something to ponder for sure, down under. ...TSS

Variably protease-sensitive prionopathy: A new sporadic disease of the prion protein

http://creutzfeldt-jakob-disease.blogspot.com/2010/08/variably-protease-sensitive-prionopathy.html



SO, cows can transmit BSE to humans as nvCJD in every country but the USA, but here in the USA, it's a new prionpathy that is genetic, but yet sporadic, because of no related mutation, not related to cows, even though one of the USA mad cows has the same type genetics, and even though Kong et al said that same type cow h-BSE is transmissible to humans. interesting isn't it $$$


http://creutzfeldt-jakob-disease.blogspot.com/2010/08/variably-protease-sensitive-prionopathy.html



SOUND SCIENCE and public health, should NOT be based on 'may not's, and 'may's'. BUT that is how the O.I.E. and the U.S.D.A. have operated for years and years. The whole mad cow debackle was based on 'may's' and 'may not's', and look where it has gotten us. The O.I.E. and the U.S.D.A. systematically changed T.S.E. science to meet their needs, i.e. TRADE, TRADE, TRADE $$$ HOW in the world, or the better question might be WHY would you put the cart before the horse so to speak with human and animal life, on a disease that we know is 100% fatal once exposed and clininal. THE theory of no transmission of typical scrapie to humans, this theory and any evidence there from is very thin to say the least. Let's look at some sound science on atypical Nor-98 Scrapie, shall we ; [Although atypical scrapie is not yet ruled out, it is important to realize this is a type of scrapie that thus far has only tended to appear as a sporadic condition in older animals. Currently it has not been shown to follow the same genetic tendencies for propagation as the usual scrapie. However, the atypical phenotypic appearance has been shown to be preserved on experimental passage. Atypical scrapie was first identified in Norwegian sheep in 1998 and has subsequently been identified in many countries, as Australia may join that list. It is likely that this case will be sent to the UK for definitive conformation. [Ref: M Simmons, T Konold, L Thurston, et al. BMC Veterinary Research 2010, 6:14 [provisional abstract available at ]

"Background ----------- "Retrospective studies have identified cases predating the initial identification of this form of scrapie, and epidemiological studies have indicated that it does not conform to the behaviour of an infectious disease, giving rise to the hypothesis that it represents spontaneous disease. However, atypical scrapie isolates have been shown to be infectious experimentally, through intracerebral inoculation in transgenic mice and sheep. [Many of the neurological diseases can be transmitted by intracerebral inoculation, which causes this moderator to approach intracerebral studies as a tool for study, but not necessarily as a direct indication of transmissibility of natural diseases. - Mod.TG]

"The 1st successful challenge of a sheep with 'field' atypical scrapie from an homologous donor sheep was reported in 2007.

"Results -------- "This study demonstrates that atypical scrapie has distinct clinical, pathological, and biochemical characteristics which are maintained on transmission and sub-passage, and which are distinct from other strains of transmissible spongiform encephalopathies in the same host genotype.

"Conclusions ------------ Atypical scrapie is consistently transmissible within AHQ homozygous sheep, and the disease phenotype is preserved on sub-passage."

Lastly, this moderator wishes to thank Terry Singletary for some of his behind the scenes work of providing citations and references for this posting. - Mod.TG]
