Sudden Sensorineural Hearing Loss During Oral Anticoagulant Therapy
This study investigated the occurrence of sudden sensorineural hearing loss (SSNHL) as an adverse effect in the treatment of patients using vitamin K antagonists (Phenprocoumon; Marcumar, Falithrom) as anticoagulants. Dr Andreas Müller and colleagues of the Department of Otorhinolaryngology, Friedrich-Schiller-University, Jena, Germany studied the records of patients who were undergoing oral anticoagulant therapy and were then admitted to the ENT Department due to SSNHL (at University Hospital, Jena, Germany from 1998 to 2001). The pure-tone audiograms and the prothrombin time (PT) values before and after the event of the SSNHL were evaluated. This work has been reported recently in the Journal of Laryngology and Otology. - Medical World Communications, German Research, 30th December 2004
Sensorineural Hearing Loss Associated with Psoriatic Arthritis
A case of sudden-onset sensorineural hearing loss in association with psoriatic arthritis (which has not been previously reported in literature) has been reported. So psoriatic arthritis can now be added to the list of other autoimmune diseases that can lead to sensorineural hearing loss. This work has been recently published in the Journal of Laryngology and Otology by Mr B.N. Kumar F.R.C.S (Consultant ENT Surgeon) and colleagues from the Department of Otolaryngology, Royal Albert Edward Infirmary, Wigan, UK. - Pharmacy Times, UK Research, 30th December 2004
New Treatment for Sudden Hearing Loss
Staff at Loyola University Medical Center (Illinois, USA) have used a new treatment to help alleviate this problem. A tiny sponge called the microwick is placed through the ear drum and then steroid drops are put directly into the inner ear through the micowick. Dr Sam Marzo of Loyola University Medical Center said that the beauty of the treatment was that patients were able to apply the drops themselves. - CBS2 Chicago , USA, 29th December 2004
Ear Infection? Antibiotics May Not Be the Best Choice
Concern about the rising rate of antibiotic use in acute otitis media (middle ear infection), leading to resistance to the antibiotics by the bacteria involved, has prompted the new guidelines in the USA encouraging lower use of antibiotics. Some alternative suggestions have been given in the guidelines and these are summarised here. - Health Day News, USA, 28th December 2004
Researcher Receives Grant to Study Genetics of Hearing and Balance Disorders
Professor Elba Serrano (Associate Professor of Biology), of New Mexico State University (USA), has received a $492,000 grant from the National Institutes of Health (USA) to study hearing and balance disorders. Her goal is to gain knowledge of the workings of inner ear sensory cells, that will help develop treatment and cures for both hearing and balance disorders. Prof. Serrano is cloning genes found in the inner ear and is especially interested in the genes for ion channels that are responsible for the electrical signals that are relayed from the ear to the brain. She also has constructed cDNA libraries from the inner ear and brain and she intends to use these to help identify genes that are important in normal development of the inner ear. She hopes to discover genetic mutations that can cause inner ear disorders. Her studies will help to test theories about how the sensory hair cells develop their unique sensory properties, and to find methods to stimulate the cells to regenerate. - Silver City Sun News, USA, 20th December 2004
Staff Claim for Hearing Problems
A number of former car workers are making compensation claims for hearing problems which they say were caused by working in a noisy factory (Swindon Pressings Ltd) in Swindon, UK, which manufactures car body parts. The former employees say that their employers failed to provide them with ear protection. It became law in the UK for staff working in noisy areas to wear ear protection after a test case 1963. However it is claimed that ear protection was not introduced at the Swindon plant until the early 1990s. - BBC News, UK, 20th December

Diagnosing Inner Ear Hearing Loss Now Less Invasive with Genetic Testing A new study by Dr John H. Greinwald, Jr. and colleagues (of Cincinnati Children’s Hospital Medical Center, USA) shows that genetic testing offers a faster, simpler and cheaper way of diagnosing inner ear hearing loss in children. They have developed a gene-based diagnostic test, that uses a gene chip and microarray technology, to provide a rapid and accurate means for analysing nucleic acid samples. The gene chip can test for the genetic causes of existing hearing loss and for the potential of future hearing loss in infants. It is expected that the test will become widely available in 2005. At this point the gene chip targets 13 key genes (there are thought to be over 150 involved in hearing loss). In their work the researchers found that screening for the GJB2 gene, as the initial diagnostic test of choice was particularly effective. The study showed that using existing non-genetic diagnostic tests left 80 percent of patients with hearing loss undiagnosed
after their initial assessment. As a results hearing loss in infants is
often undetected for many months after birth. Dr Greinwald said, that early
detection and intervention could alleviate most of the developmental and
behavioural difficulties found in hearing impaired children, as the earlier
intervention the greater the enhancement of speech and language skills.
Dr Greinwald said, "Genetic testing can not only determine the cause
of the hearing loss, but can help determine how a child’s hearing
will progress as the child ages. What will the child’s hearing be
like later in life? That’s why this research is so important. This
is predictive information. It is not absolute, but it is very good." This
work is published in the December 2004 issue of Otolaryngology - Head and
Neck Surgery. - www.innovations-report.de, USA Research, 17th December

New
Zealand Children’s Hearing at Risk
In the last ten years, the average age for identifying children born with hearing
loss in New Zealand has increased from two to nearly four years of age. Marianne
Schumacher, executive manager for the National Foundation for the Deaf (NFD)
in New Zealand, said that one of the most serious problems resulting from late
detection of hearing impairment is delayed language development during the
critical period for language acquisition. Peter Thorne, Associate Professor
of Audiology, at Auckland University said, “New Zealand quite possibly
has the worst statistic in the developed world for the early detection of hearing
loss." Professor Thorne is in charge of a project group asking for a a
national newborn screening and intervention programme to be introduced in New
Zealand. - Scoop, New Zealand, 16th December 2004
Third
Language Area in Brain Identified
Researchers at the Institute of Psychiatry, King's College, University
of London (UK), have identified a third language area in the brain involved
with language processing. Before
this, it was believed that just two areas of the brain (the Broca's and
Wernicke's areas) handled language: one area produced language and another
another area was responsible for comprehension. The researchers used diffusion
tensor magnetic resonance imaging (a more powerful version of standard
MRI) to identify this third area, which they have called Geschwind's territory.
The name honours American neurologist Norman Geschwind, who championed
the idea of a third linguistic area decades ago. Dr Marco Catani the lead
author for the study said that they were surprised to find that the two
classical areas were densely connected to a third area, and that an important
future line of study will be to examine the maturation of this area and
its connections in the context of autism and dyslexia. The study appears
in the online edition of the Annals of Neurology (as an early view article
prior to print publication). - Heath Day News, UK Research, 13th December

Brain
can be Trained to Process Sound in Alternate Way
Researchers at the University of California, San Francisco (UCSF), USA, have
found that the brains of rats can be trained to learn an alternate way of processing
changes in the loudness of sound. The discovery, they say, has potential for
the treatment of hearing loss, autism, and other sensory disabilities in humans.

Neurodevelopmental Outcomes After Preterm Birth
The major clinical outcomes that are important to premature babies and their
families have been examined by William McGuire and Peter W Fowlie from Stirling
Royal Infirmary, Stirling (UK). One of the areas highlighted included "hearing
impairments". About 3% of infants born at less than 28 weeks gestation
require hearing aids, though more infants have milder hearing impairment or
high-frequency hearing loss. They reported that in these cases early use of
hearing aids plus support from audiology services can improve language development
in infants with sensorineural hearing loss. This work was published in the

IVs
for kids
Researchers at Wayne State University in Detroit (USA) looked at whether the
benefits of using an intravenous catheter (IV) outweigh the displeasure for
children having minor ear surgery. They found that Children who had IVs spent
longer in the operating room, longer in recovery, and longer in the hospital
altogether. In addition children with IVs were in more pain, and parents were
happier if their children didn't have IVs. - USNews.com, USA, 9th December

Auditory
Processing Disorders to be Examined in Major Study
A major study is about to begin at The University of Auckland (New Zealand)
to find ways to help children suffering from a common but difficult to diagnose
cause of learning difficulties known as auditory processing disorders (APD).
This condition occurs when when the ears hear but the brain does not process
the signals well, and is a frequent cause of speech and language problems,
reading difficulties and dyslexia in children. Dr Andrea Kelly (Audiology section
of the School of Population Health) and her colleagues Drs Suzanne Purdy and
Mridula Sharma (from Speech Science in the Department of Psychology) are undertaking
a study examining APD in order to improve diagnosis of the disorder and identify
ways to help children overcome its effects. - Scoop, New Zealand, 8th December

Nightclub Workers
Risk Hearing Loss
Workers at noisy clubs and pubs are at risk of permanent hearing loss, according
to a report by the TUC. Research showed that in some cases that the music was
found to be so loud, that it compared to working next to an aeroplane taking
off. Currently 170,000 people suffer from deafness or other ear conditions
as a result of exposure to excessive noise at work, in the UK. The TUC (Trade
Union Council) says that around nd it is calling for more protection for bar
and club staff. Mark Hoda, spokesman for the charity group RNID (Royal National
Institute for the Deaf), which helped with the research, said that many employers
in bars and clubs are in breach of the law. - BBC News, UK, 8th December

Paget's
Disease and Cochlear Implantation
Paget's disease of bone is a common disorder characterised by excessive bone
resorption followed by excessive bone formation. If the skull is affected this
may result in hearing loss and eventually develop into profound deafness. Dr
Andrea Bacciu and colleagues (Department of Otolaryngology, University of Parma,
Italy) have the first reported case of a successful cochlear implantation in
a patient with this disease. The researchers reported the case of a male patient,
aged 77, with a 20-year history of progressive bilateral sensorineural hearing
loss and radiographically confirmed Paget's disease of the skull who was successfully
implanted. This work was published in The Journal of Laryngology and Otology

What
Colour is that Sound?
A blending of the senses occurs in a rare condition called "synesthesia." In
this condition, a stimulus, such as sound, creates a reaction in another sense,
as well as the expected sense. So this can result in people who are able to
taste or see sound as well as hear it. Synesthesia is thought to occur in just
1 per cent of all adults. Prof. Daphne Maurer (Department of Psychology, McMaster
University, Hamilton, Canada) has found that at a very young age everyone is
synesthetic. She discussed evidence that all infants are synesthetic at the
annual meeting of the American Synesthesia Association on 6th November 2004. -

New
Tools to Help Patients Reclaim Damaged Senses
A new device called the Brain Port has been used to regain normal vestibular
function. It involves placing a thick strip of tape, the size of a stamp,
containing 144 microelectrodes on to the tongue for a short time each day.
The strip is wired to a carpenter's level type device on a hard hat on
the head, which determines the patients coordination and then sends pulses
to the tongue. This technique uses a technology that allows one set of
sensory information to substitute for another in the brain. (This
method can also help to restore other senses such as sight and touch be
re-routing them to other parts of the body such as the tongue, skin or
ears). The technology for swapping sensory information is largely the effort
of Dr Paul Bach-y-Rita, a specialist in Rehabilitation Medicine at the
University of Wisconsin Medical School. Work which he started on 30 years
ago. Next month, the first fully portable device will be tested in Dr Bach-y-Rita's
lab. The Brain Port is nearing commercialisation. Two years ago, the University
of Wisconsin (USA) patented the concept and licensed it to Wicab Inc.,
a company formed by Dr. Bach-y-Rita. There are only a handful of clinicians
around the world who have used the BrainPort on an experimental basis.
Dr F. Owen Black, an expert on vestibular disorders at the Legacy Clinical
Research and Technology Center in Portland, Oregon (USA) says that he has
never seen any other device do what this one does and that their patients
are begging them to continue to use the device.- Herald Journal, USA,

Stem Cells
Could Improve hearing
Various news stories from a one day conference organised by the Royal National
Institute for Deaf People (RNID) held in London (UK) have been discussed here
including: 1. Work by Dr Marcelo Rivolta,
from Sheffield University. He is using stem cells from embryos and trying to
learn how to convert them into cells for the human ear. Dr Rivolta said that
his research had shown that stem cells from sensory nerves could be regrown
in a damaged part of the ear which, potentially, could restore a person's hearing
for certain types of hearing loss such as; those people who have lost their
hearing as a result of degeneration of the cochlear, those who've lost hair
cells because of loud noise or drug treatments, and people with certain genetic
conditions. 2. The first trials of a drug,
codenamed SPI 1005, which treats hearing loss are currently being conducted
using eighty soldiers (from the USA army) involved in live weapons training
with handheld rifles. The product has been developed by Sound Pharmaceuticals,
who hope that it will be on the market in about three years. - BBC, UK,

Mild Hearing Loss Affects Kids' School Performance
At the annual meeting of the American Speech-Language-Hearing Association in
Philadelphia, Dr. Anne Marie Tharpe (Vanderbilt University in Nashville, Tennessee,
USA) presented the results of two studies that measured childrens' hearing
and compared it to their performance at school. The studies included approximately
2000 students, not all of whom had hearing disorders. It was found that children
with hearing problems, even minimal, were significantly more likely to have
academic problems. Children with impairments such as a loss of hearing in one
ear, or an inability to hear sounds of certain pitches, were found to be 10
times more likely to have scholastic difficulties than normal-hearing children.

Steelband Musicians May Suffer Hearing Loss
A new report by researchers at the University of the West Indies at St. Augustine,
Trinidad, showed that musicians with long term exposure (of over 20 years)
to the Steel-Pan instrument had a greater hearing loss, than others who were
not exposed. Dr. Solaiman Juman, the lead author said this showed that steel-pan
players required hearing protection, or they would be at risk of getting a
noise-induced hearing loss, with time. This is of particular concern as many
steel pan musicians are reluctant to use ear protectors, as this may hinder
them from noticing slight differences in musical tones, and many are starting
to play the instrument at an increasingly younger age (as early as 10 years
old). This study has been reported in the journal "Otolaryngology - Head and
Neck Surgery" - Reuters

Pitt
Research Cave Sheds Light on Dizziness
University of Pittsburgh researchers (USA) have collaborated with computer
experts from the Georgia Institute of Technology (USA) to develop the Balance
Near Automatic Virtual
Environment (BNAVE), nicknamed "the cave". This involves a virtual
reality display room large enough for people to immerse themselves in a
computer-generated visual environment such as large geometric patterns,
a grocery shop or the top of a skyscraper with appropriate lighting / brightness
etc. A helmet equipped with miniature video cameras tracks their eye movements
and the floor is a platform capable of measuring the forces under a patients
feet as they respond to the environment. Dr. Mark Redfern, the centre's
co-director and a Professor of Bioengineering and Otolaryngology at the
University of Pittsburgh said that virtual reality provides a safe environment,
as well as quantifiable, instant changes to be made to tailor the therapy.
The project has cost nearly $200,000 and was paid for with grants from
the Eye and Ear Foundation and the National Institutes of Health (USA).
It is hoped that within the next year the BNAVE will be put into use as
a rehabilitation tool for patients with balance disorders. - Pittsburgh

Scientists
Closing In On Nerve Proteins’ Contributions to Memory and
Hearing Loss
Jianxin Bao (research assistant professor of otolaryngology)
and other researchers, at Washington University in St Louis School
of Medicine, have shown that two
key nervous system proteins interact in a manner that helps regulate the
transmission of signals in the nervous system. These are neuregulin-1
(Nrg-1), a protein
linked to schizophrenia, and postsynaptic density protein-95 (PSD-95), a
protein associated with Alzheimer’s disease. (Publication
in Nature Neuroscience, Nov 2004). Jianxin Bao suspects age-related
decreases in Nrg-1 levels may be
linked to hearing loss and memory loss, and has begun research to investigate
the effects on hearing. - Washington University in St Louis School of Medicine

Professor
Graeme Clark - Winner of the Prime Minister's Science Prize (Australia)
Cochlear was named Australia's top innovator for the third year running. The
transcript of a radio interview with Professor Graeme Clark is given here.
The Prime Minister's Prize for Science honoured Professor Graeme Clark for
the discoveries that led to the bionic ear. The latest discoveries of Professor
Clark and his colleagues at the Bionic Ear Institute involves making nerve
cells in the inner ear re-sprout. Professor Clark said, "the discoveries
will not only allow us to have more nerves to stimulate to give us better quality
sound, but we also are aiming to preserve the nerves from dying back which
happens in deafness and, there's another exciting challenge facing bionic ears
and that is being able to operate on ears that have residual hearing, so we're
also hoping that we can preserve hearing and actually operate on them at the
same time." Professor Clark said that it was a major discovery in neuroscience
and they were hoping to apply it to the ear, and also follow on with helping
people with spinal cord injury. - Radio Australia - ABC, 24th October

MRI Should Be the Preferred Test for Evaluating Sensorineural Hearing
Loss
A study, published in the October edition of Laryngoscope suggests
that magnetic resonance imaging (MRI) be the preferred test for evaluating
asymmetric sensorineural
hearing loss rather than auditory brainstem response (ABR) testing. "These
findings are important because, even though MRI is more expensive than ABR,
we recommend its use to achieve earlier tumour detection and better treatment
results," said Dr Roberto A. Cueva, the study's main author. - Business

Scientists
find Molecular Key to Hearing
Researchers believe they have discovered the final link in the physiological
process that enables us to hear. That last connection is a molecule (TRPA1

'Astronaut
Therapy' Aids Hospital Patients' Balance Problems
Training given to fighter pilots and astronauts has been adapted to treat
patients with balance problems. The
sessions combine rotating disk, spinning chair and video-based exercises
that create the illusion of movement. Study leader Professor Adolfo Bronstein,
head of the department of neuro-otology at Charing Cross Hospital (London,
UK) said: “Input from your muscles and joints, your inner ear and
your eyes make up the triad of sensory information your body needs to stay
balanced. In patients with inner ear damage, we thought that by strengthening
the other inputs this would lead to a reduction in dizziness. We found
that the frequency and intensity of dizzy spells was reduced, along with
an improvement in balance and co-ordination in all patients, more so in
the half that received the visual simulations. These exercises, which are
used to train pilots to avoid motion sickness, are simple to set up so
we are confident that they will soon become part of the standard treatment
programme for chronic dizziness.” This work was reported today in
the Journal of Neurology. - scotsman.com, UK, 7th October

Background noises.... may actually scramble brain activity
Research by the University of Florida showed that background noise didn’t
simply cover up sounds, it interfered with the brain’s ability to process
or interpret information about a sound, even though the sound was heard. Essentially,
the brain couldn’t understand what the ear told it. “Some people
have a tremendously difficult time understanding speech in a noisy environment..” said
Purvis Bedenbaugh, an assistant professor of neuroscience with the University
of Florida College of Medicine (& McKnight Brain Institute, UF). “This
research is a first step toward looking at why that would be.” This work
is detailed in the current Proceedings of the National Academy of Sciences. It
is thought that the phenomenon may play a role in auditory processing disorder,
a problem first noticed in children in the 1970s. The lack of coordination between
the ear and brain that characterizes the disorder is expected to be widespread,
although it is difficult to diagnose, according to the American Academy of Audiology.

Study Suggests Vitamin
E Can Restore Hearing
Recent research, by the Technion-Israel Institute of Technology, suggests Vitamin
E can help restore hearing in people who become deaf suddenly for no known
reason (see news story below dated 17.09.04). About 123,000 people in the UK
experience sudden so-called "sensorineural" hearing loss. Often this
can be a viral or bacterial infection or trauma. However, in about 10-15% of
cases there is no obvious cause and this is called idiopathic sensorineural
hearing loss. Munna Vio, from the RNID, which represents deaf and hard of hearing
people in the UK, said that it was a very encouraging study and that the RNID
was funding similar research into antioxidants, including vitamin E, as a way
of treating hearing loss. - BBC News (UK), comments on Israeli Research, 25th September 2004

it. “The brain problems are fundamentally in terms of feedback system.
It's the controlled systems that are coming back to the ear," said Robert

NASA flight surgeons and researchers studying weightlessness, examine motion
sickness from weightlessness. Inside the human inner ear are three semicircular
canals, part of the vestibular system, that serve as accelerometers using tiny

on the Earth's surface, where the body expects, and rightly so, the steady
pull of gravity. But during a parabolic flight or the initial days of weightlessness
in space, the body's internal balance system is cast into confusion. - Space.com (this website gives pop-up ads),

A study was carried out to explore clinically the role of hearing in development
of sensorimotor integration and non-verbal cognition. It was found that auditory
impairment does not cause a pathological delay or distortion in non-verbal
development but it does produce subtle differences in certain motor and neuropsychological
functions. This observation is an interesting demonstration of the extent of
the role of hearing in the building of the brain. Language impairment is not
the only consequence of deafness on neuropsychological development. (Published

MRI
Identifies Causes of Sudden Deafness
Past research has revealed that in an MRI examination of 495 sudden deafness
cases, 22 showed evidence of intra-axial lesions. This gave a research team
a central etiologic basis for the deafness; the possibility of lesions in the
audiovestibular pathway has been considered by other researchers to be one
of the principal causes of sudden hearing loss. A new study by researchers
from the Federal University of São Paulo (Paulista Medical School),
Brazil reports on the abnormalities found after an MRI examination of patients
with sudden deafness. Presentation of this work was given at the American Academy
of Otolaryngology-Head and Neck Surgery Foundation Annual Meeting & OTO

Botox
Injections May Ease the Irritation of Tinnitus
A preliminary study indicates that Botox injections may ease the irritation
of tinnitus, otherwise know as ringing in the ears, for some patients. Researchers
say more study is needed, but initial results are promising. - News-Medical,

Study
Hints at Antioxidants being able to Prevent and Restore Hearing
Loss
In a preliminary study, researchers found that vitamin E may be effective in
restoring sudden onset hearing loss of unknown origin (idiopathic sudden hearing
loss). These findings suggest that further research may reveal the role of
antioxidants in the prevention and restoration of hearing loss. See also the press
release on nlm.nih.gov. This study is the work of researchers from Rambam
Medical Center and Faculty of Medicine and Technion-Israel Institute of Technology.

Kids Give
Language its Shape
An extensive study of deaf Nicaraguan children found that they refined sign
language. "These children are actually creating language. This was a rare
opportunity to discover a new language as it's emerging," said study author
Ann Senghas, an assistant professor of psychology at Barnard College of Columbia
University in New York City. The study followed several generations of deaf
Nicaraguan children as they created their own sign language and then continuously
tinkered it with each new group of signers. This work appears in the 17 September
issue of Science.- HealthDay News, USA Research, 16th September

Left
And Right Ears Not Created Equal ...
Research on newborns by University Of California, Los Angeles (UCLA) and University
of Arizona (UA) has shown that the way that right and left ears process sound
differs from one another. Yvonne Sininger's findings suggest that the difference
is inherent in the ear itself. "We always assumed that our left and right
ears worked exactly the same way," she said. "As a result, we tended
to think it didn't matter which ear was impaired in a person. Now we see that
it may have profound implications for the individual's speech and language
development." This work published in the 10th September edition
of Science, could hold profound implications for rehabilitation of persons
with hearing loss in one or both ears, and help doctors enhance speech and
language development in hearing-impaired newborns. - UCLA

Bionic
ear to hear sweet music
A new-generation bionic ear that turns noise into music is one step closer
after Australian researchers have shown they can resprout delicate nerve fibres
lost in deafness. The research, led by Professor Graeme Clark of Melbourne's
Bionic Ear Institute, has been submitted for publication. Clark was last night
awarded the A$300,000 Prime Minister's Prize for Science for his pioneering
research on the bionic ear, or cochlear implant. When hair cells are lost,
a person has difficulty in picking up sound vibrations, the fundamental cause
of sensory hearing loss. Clark said the bionic ear was designed to bypass the
function of hair cells by using electrodes to directly stimulate the nerves
to communicate with the brain. - ABC Science Online, Australia, 8th September

Deaf Children Have a Right to the Sound of Silence?
Scientists are ever closer to "curing" deafness, through developments

Hagan in the New Scientist (August 28). The last thing these scientists anticipated
was that their research would be met with deep resentment by large sections
of the deaf community. - The Guardian, 1st September 2004

Music
Providing Some Relief For Tinnitus
Audiologist Rich Tyler is studying whether music can help tinnitus. One theory
is that the condition is caused by abnormal brain activity. Tyler says music
may impact that. "There is a chance that, through extended period of listening
strategies, that the pattern that is responsible for the tinnitus in the brain
might actually be broken up." The study is being conducted only at the University
of Iowa. - wave3.com, Louisville, Kentucky, USA, 31st August 2004

Cell Phone Could Cause Hearing Damage
Siemens issued a warning that some of its mobile phones may have a software
problem that could cause them to emit a loud noise, possibly causing hearing
loss for the phone user. When that happens, the phone may begin playing a very
loud "shutdown melody" and if a user is still holding the phone to
his or her ear, it may present some risk to the person's hearing. - Canadian

Rosemary
McCall
For the audiologist Rosemary McCall, who died aged 85 on 3rd August,
the most important thing to offer deafened people was empathy, support and the
confidence to begin communicating again. Postwar she began her career in audiology
and immediately recognised the lack of support for ex-service personnel, and
for elderly deaf people. After working with a deafened lady from Ireland, she
had an idea to start social rehabilitation with a holistic approach, taking into
account the wider health and circumstances of the individual, and involving the
family. So an organisation called Link was started in her living room. In 1998,
she was awarded the OBE for her services to deafened people. - The Guardian Newspaper (this website sometimes gives a pop-up),

Research Explains Lag in Onset of Common Type of Vertigo
A reason explaining why people
suffering from the most common type of vertigo experience a distinct
time lag between a rapid head motion and the onset of dizziness
may have been found. The
researchers say that it takes five to six seconds for minuscule
crystals in the
inner
ear to
sediment after the head moves suddenly, an event that can set
a dizzy spell in motion. A
team of engineers and physicians from Harvard University (including Professor
Howard A. Stone - pictured), the California Institute of Technology, and
