New examine from the Howard Florey Institute in Melbourne has shown why mutation in a individual gene can movement epilepsy in infants.

Infants are more susceptible to seizures because their brains are developing at a rapid rate, making their brain cells ‘excitable’. Their neurons are growing and making new connections with other nerve cells, which can disrupt normal brain activity and results in epilepsy.

Infants have protective mechanisms in their brains to control this excitability, but now the Florey scientists have uncovered that a single gene mutation prevents a specific ion channel from functioning correctly, thus causing excitability which results in epilepsy.

Dr Steven Petrou and his team knew the genetic mutation existed, but did not know its impact on brain function or that it may control excitability in infants’ brains.

“This discovery is helping us to understand how and why this form of epilepsy, known as benign familial neonatal-infantile seizures, appears in these infants,� Dr Petrou said.

“Interestingly, we also found that the ion channel which carries the mutation is itself naturally protective as it limits excitability in the infant brain by waiting to fully ‘switch on’ only in the adult brain.

“The mutation accelerates this normally delayed development change, leaving the susceptible infant brain with an overly excitable channel and epilepsy.

“If this switch to a more excitable state occurs too early during brain development, it is possible that epilepsy and other neurological disorders develop.

“This highlights the complexity of the human brain and how disorders can develop if one single mechanism goes awry,� he said.

This research was recently published in Molecular and Cellular Neuroscience. According to Dr Petrou, potential new avenues of research may emerge from this study.

Epilepsy affects 3% of the Australian population and better treatments are urgently needed as many existing therapies have serious side-effects for patients. In 30% of cases, the current drug options available provide limited seizure relief.

There are more than 200 types of epilepsy, which can either be inherited or result from a range of causes including, head trauma, vascular disease or brain tumours.

Occlusion of the basilar artery (BAO) is a relatively infrequent but the most catastrophic form of ischemic knock with a gloomy organically grown course, carrying from 85 to practically 95 % mortality.

Complete BAO precipitates a sudden or gradually worsening clinical syndrome with bilateral motor weaknesses, visual or speech disturbances, deficits in motor coordination and balance, and often leads to reduced consciousness. The most devastating end-point is the locked-in state, in which the patient is conscious but can move only his or her eyes. Many stroke centers have in the past used invasive, intra-arterial thrombolysis to recanalize BAO, which is limited to hospitals with immediate invasive radiologist service.

Previous reports have advocated thrombolytics delivered with invasive endovascular approach to the occlusion site, but even a short delay in the onset of therapy has been reported to be the single most critical factor affecting outcome. Due to unacceptable treatment delays, Finnish neurologists led by Docent Perttu J. Lindsberg and Professor Markku Kaste at Helsinki University Central Hospital reverted from intra-arterial approach to noninvasive, intravenous delivery of alteplase, a protocol used more commonly in anterior circulation strokes. The results of this study were published 20.10.2004 in JAMA (Journal of American Medical Association).

Since 1995, 50 patients with proven BAO were treated in Helsinki according to institutional thrombolysis protocol. By 3 months, 20 patients (40%) died, while 12 patients (24%) reached independence in activities of daily life. On the long-term, patients with recanalized basilar artery and fair outcome continued to improve functionally and survivors reported unexpectedly satisfactory ratings of the quality of their daily life.

Rates of survival, recanalization and independent functional outcome are at least equally good than reported with endovascular invasive approaches, but the benefits of intravenous therapy are that it can start thrombolysis faster and can be used more widely than the invasive approaches.

While the placement of stents in newly reopened coronary arteries has been shown to reduce the penury conducive to rehearse
angioplasty procedures, researchers from the Duke Clinical Inspect Organization sooner a be wearing create that stents have no impact on
mortality over the yearn term.

In the largest such analysis of its kind, the Duke researchers said their findings have important economic and clinical
implications for physicians who are deciding whether their understanding patients should receive coronary artery bypass surgery, or
less-invasive angioplasty, which includes the placement of a stent.

Stents, which were introduced in the U.S. in 1994, are pocket decussation tubes that are inserted at the site of a blockage in a
coronary artery that has been opened during balloon angioplasty. The procedure seeks to prevent the artery from becoming
blocked again, a process known as restenosis. These blockages, caused by atherosclerotic plaque, can starve the heart of
oxygen-abundance blood and flex to a heart attack.

Duke cardiologist David Kandzari, M.D., who presented the results of the Duke critique Nov.7, 2004, at the American Heart
Association’s annual scientific sessions in Creative Orleans, said the findings on mortality rates should also be expected to show
true into the latest generation of pharmaceutical-eluting stents. These stents, which were introduced in 2003, are coated with a analgesic
that keeps blood clots from forming propitious them.

“We have initiate in our long-term examination that stents do provide a significant early and sustained reduction in the need for
subsequent procedures to re-obtainable the treated artery,” Kandzari said. “However, we also found that stents do not own any
work on on long-provisions survival.

“Since earlier studies have on the agenda c trick shown that new narcotize-eluting stents can lessen the incidence of restenosis, we would wait for the
need for repeat procedures to degeneration even more as these stents become more widely acclimatized,” Kandzari continued. “While earlier
trials of drug-eluting stents be subjected to demonstrated a expressive reduction in repeat procedures, they still cause shown no
differences in mortality compared with more conventional stents.”

Specifically, the researchers found that past the normally seven-year cultivate-up period of their reading, 19 percent of patients
who received a stent needed another revascularization procedure in the treated artery, compared to 27 percent owing those who
did not welcome a stent. However, the long-entitle mortality be entitled to against those receiving a stent was 19.9 percent vs. 20.4 percent
for those who did not, a disparity which did not statistically quarrel.

For their analysis, the researchers consulted the Duke Database for Cardiovascular Disease, which keeps particularized clinical
observations on all verve patients receiving treatment at Duke. The researchers identified 1,288 matched pairs of patients who
underwent either balloon angioplasty alone or stenting — yet all had a similar probability of receiving a stent based on
their clinical and demographic characteristics.

The patients, 63 percent of whom were manly and who had an average age of 59 years, were treated between 1994 and 2002. One in
four was diabetic, and one in four had suffered a previous middle corrode.

“This deliberate over, based as it is on a real-world residents of patients, tells us that stents do not save lives, despite the fact that they do
have a obscure effect on avoiding repeat procedures,” Kandzari said. “We’ve advised of that restenosis has in no way been
scientifically associated with increased mortality, but it has been associated with an increased for for revascularization
and with a reduction in symptoms such as casket pain.”

Given these findings, Kandzari said physicians treating their heart patients should not automatically presuppose that placing a
stent, whether the character unmask-metal type or the newer medicament-eluting version, choose be the end of treatment.

“Many physicians will successfully place a stent and think that’s it,” Kandzari continued. “The bigger issue is that many of
these physicians should also then be prescribing drugs that must a clearly demonstrated beneficial form on long-term
mortality.”

Kandzari plans to follow up this study with a similar analysis of the effects of the drug-eluting stents on mortality. Also,
the team plans to measure any differences in the status of life of these patients.

“As we ingest on more and more particular and complicated cases in the catheterization lab, we should take a step back to see if
there are certain instances when get round surgery may be the greatest selection,” Kandzari said. “There is the persuading entirely there to
honest place stents in all patients, no matter what. In some former trials, the contradistinction in outcome between angioplasty and
surgery patients was driven by restenosis, not by differences in mortality.

“However, in the generation of everyday stenting, we knew that there we in any event some instances in which skirt surgery influence
yield an incremental survival profit,” Kandzari said. “Before routinely placing drug-eluting stents in be like patients,
these findings underscore the call for for systematic estimation of medicine-eluting stents in these types of patients.”

Patients with left main coronary artery disease, in spite of example, appear to fare well-advised b wealthier with bypass surgery than with angioplasty
and stents. Previous over has also suggested this may be true for diabetic heart patients with extensive affliction, who appear
to benefit the most from bypass surgery, Kandzari said.

“Appropriately, a essay is close at hand to compare treatment with drug-eluting stents with bypass surgery in diabetic
patients,” he said.

The study was supported by the Cordis Corp., Miami Lakes, Fla., which develops stents. Kandzari has no financial consequence profit in
Cordis.

Other members of the Duke team were Robert Tuttle, M.D., James Zidar, M.D., and James Jollis, M.D.

Over 50 percent of patients with pump loser also have kidney disease and this unstable suspension results in poor survival, Yale School of Medicine researchers report in the Journal of the American College of Cardiology.

The researchers contrived 80,098 heart failure patients, combining details from 16 prior studies and comparing survival in those patients with and without kidney disease.

“A growing number of patients in the United States accept both spirit dud and kidney disease. Both of these conditions are costly and burdensome,” said take author Grace Smith, M.D., a student in the Department of Epidemiology and Influential Health at Yale School of Medicine. “While our office confirmed that heart crash patients with kidney disease had worse survival, we were surprised to catch sight that an noteworthy number of goodness failure patients had kidney disorder. Over half of the patients had at least mild bug and almost one third had moderate to stony contagion.”

When followed payment at least solitary year, 38 percent of patients with equable disease had died, as had as many as 51 percent with moderate to stringent disease. “These mortality risks are comparable to risks attributed to deadly cancers,” said Smith.

“Of even more concern is the lack of treatment options in compensation patients with resolution breakdown and kidney disease,” said senior designer Harlan Krumholz, M.D., professor of internal medicine, section of cardiology. “These patients have traditionally been excluded from clinical trials, most disposed to due to the severity of their illnesses.”

“Our results emphasize that we call for to understand outcomes in these patients in order to remodel treatment strategies,” said Krumholz. “This details may require energy for future inquiry on interventions to metamorphosis survival in this sick but well-founded subgroup of heart failure patients.”

Co-authors on the study include Judith Lichtman, Michael B. Bracken, Michael Shlipak, Christopher Phillips and Paul DiCapua.
