"Dizzy No More?"
16 May 2013 - Emeritus Professor W P R Gibson AM resigned as President to become Secretary. Mr Leo Tutt was appointed President. By unanimous agreement of the Committee.
The 2013 Fund Raising Appeal was launched at the end of April 2013.
25 January 2013 - Dr Yasuhiro Chihara following completion of his two year appointment to the Meniere’s Research team, was farewelled prior to his departure to Japan and to an appointment in Singapore. He will be sadly missed as his contribution was greatly appreciated.
4 December 2012 - Several donors contributed to a scholarship fund to be named “The Bruce Kirkpatrick Meniere’s Research Scholarship Fund”. The annual award of a prize for the best essay on this research will be determined by a committee chaired by Emeritus Professor W P R Gibson AM.
27 January 2013 - Laboratory Research: The Ménière's Research laboratory at The University of Sydney, headed by Dr Daniel Brown, was successful in landing a National Health & Medical Research Committee project grant award, for $307,000 to help them continue with their experimental animal work in the laboratory. Furthermore, the group's collaborative research with Prof Ian Curthoys from the University of Sydney also landed a $300,000 "Garnett Passe & Rodney Williams Foundation" project grant. These grants will enable the Ménière's research group to continue their research into the physiological mechanisms underlying the primary symptoms of Ménière's. The group have already published 2 scientific papers in 2013, with 2 more currently under editorial review, and several more in the publication pipeline.
Brown DJ, Chihara Y, Curthoys IS, Wong Y, Bos M. 2013. Changes in cochlear function during acute endolymphatic hydrops development in guinea pigs. Hearing Research, 296, 96-106 Chihara Y, Wong Y, Curthoys IS, Brown DJ. 2013. The effect of systemic administration of desmopressin on cochlear function in guinea pigs. Acta Otolaryngologica, in publication.
This funding and publication success comes on the back of the group's recent discovery and demonstration first, that the systemic anti-diuretic hormone vasopressin has little impact on cochlear and vestibular function in laboratory animals, and second, that abrupt changes in both cochlear and vestibular function occur during experiments designed to mimic the development of endolymphatic hydrops (the hallmark of Ménière's Disease). This later research demonstrated episodes of hearing recovery along with vestibular dysfunction. Previous researchers had theorized that such an event would occur if the endolymphatic compartment of the inner ear ruptured with hydrops: the so called "Rupture theory" of Ménière's vertigo attacks. However, the Ménière's research team provided evidence that there is no rupture, but instead, the functional changes may be related to a sudden opening of physiological valves that separate the hearing organ (the cochlea) from the balance organ (the vestibular system). To visualize structural changes in the inner ear causing what the group believes to be similar to a Ménière's vertigo attack, they used high resolution X-Ray imaging of the inner ear, along with a kind of dye to demonstrate conclusively that severe endolymphatic hydrops does not cause a rupture.
These results do at least two things for us; they provide a clearer picture of what is happening in a Ménière's sufferer's ear, and they also identify fundamental mechanisms in the ear that regulate endolymph volume, such as protein channels which open when the endolymphatic compartment swells. The group believes the pathology of these fluid regulation mechanisms is the cause of Ménière's Disease. Now that they have a way of monitoring the function of these mechanisms in the ear when they are stressed, the next phase of the Ménière's group's research will be to test drugs and treatments aimed directly at manipulating these physiological mechanisms. This will hopefully provide an effective cure for endolymphatic hydrops and Ménière's.
Clinical Trials: Over the last year and a half, the Ménière's Research Laboratory at The University of Sydney has been investigating the feasibility of running a clinical trial to test if antiviral drugs can provide an effective treatment for Ménière's symptoms. While the group still aims to perform such a trial, there have been several hurdles to overcome, primarily due to the difficulty and expense of running placebo-controlled drug trials such as these, particularly given the fluctuating nature of Ménière's Disease which will ultimately require numerous sufferers to be treated, each over the course of a full year. The Ménière's Research group is now looking for additional funding to engage the NHMRC Clinical Trials Centre to redesign and oversee the progress of the trial. For more information on the progress of the clinical trial, keep an eye on the Ménière's Research Fund Inc. website, or contact Prof William Gibson or Dr Daniel Brown at The University of Sydney.
Dr Chihara: Dr Yasuhiro Chihara (or "Yas") finished his 2 year sponsored work VISA contract with The University of Sydney at the end of January 2013, returning to Japan briefly with his wife Yoshie and 3 children (including 5 month old Yoshihro - born in Sydney) before he is expected to take up a new clinical position in Singapore. It has been an extremely fruitful 2 years with Dr Chihara at the Ménière's laboratory, with the group already publishing several papers and with numerous more in the works. The Ménière's laboratory will continue to collaborate with Dr Chihara for many years to come, as we wish him all the best for his new placement in Singapore.

WE HAVE RAISED AUS$1.6m SINCE 2003 AND SPENT AUS$928,639 ESTABLISHING OUR RESEARCH FACILITY
We have updated our target thermometer (at right). The Fund announces today (16 April 2012) that after having established the laboratory and employed 2 full time trained research staff, it has lifted its total funds raised target to $AUS2.5m, up from $AUS1.5m. The additional money, when raised will be directed to broaden the lines of inquiry. Since the start of the year, AUS$161,945 in donations and grants have been received by the Fund to assist us in our quest for a cure for Meniere's Disease.
Meniere’s Disease has devastating effects on the lives of those afflicted and on those who care for them. Working lives are disrupted and careers brought to an end. The normally ordered and busy lives of otherwise healthy people, suddenly become totally unreliable.
The unresolved questions surrounding the condition have been tackled for nearly 150 years without finally identifying the cause and a possible cure. While medical and surgical advances to alleviate the affliction have been encouraging, the Meniere’s Research Fund Inc (the Fund), a not for profit fund raising group run by volunteers established in 2002 as a development from the Meniere’s Support Group of NSW (now disbanded), has been stepping up the research effort. The support work across Australia is now the responsibility of Meniere’s Australia Inc.
The research program developed by the Professorial Research Committee of the Fund has explored new areas of the inner ear. Dr Yasuhiro Chihara, who joined us in April 2011, has been working with Dr Daniel Brown, our initial Research Fellow, on trials using Vasopressin to asses its effect on creating hydrops (swelling of endolymph fluid thought to underlie the cause of MD attacks). Another exciting area to be explored, perceived by both Mr Stephen Spring and Professor Gibson, is now on the cusp of new trials to validate or disprove the suppressive effect of a known drug not previously successfully administered elsewhere.
Our aim is to build up a strong research team in Sydney, to explore and build on the findings from Meniere’s research being carried out by scientists in Australia and other countries. We have been able to recruit our team due to the support we have received from our generous donors.
We are confident that with your help in maintaining and expanding the world’s first laboratory dedicated entirely to studying Meniere’s Disease, established here at the Brain and Mind Research Institute, our program will lead to enhanced early detection, preventative strategies and superior treatments sufficiently alleviating the condition to make sufferers able to again lead a relatively normal life.
