BURLINGTON, Mass.--(BUSINESS WIRE)--Dyax Corp. About Lamictal (Lamotrigine) without prescription (NASDAQ: DYAX) today announced a poster presentation
describing preclinical data for DX-4012, the Company’s fully human
monoclonal antibody to activated Factor XII (Factor XIIa), was presented
at the 57th American Society of Hematology (ASH) Annual Meeting and
Exposition taking place December 5-8, 2015 in Orlando, Florida.
“The poster presented at ASH this year describes how DX-4012

#: 83101Session: 321. About Cordarone (Amiodarone) with free Rx Blood Coagulation and
Fibrinolytic Factors: Poster IILocation: Hall A, Level 2Summary:
In this report, investigators describe the discovery and preclinical
evaluation of DX-4012 as a highly selective and potent inhibitor of
FXIIa. Intalith without Rx DX-4012 inhibits the proteolytic activity of FXIIa with an
apparent Ki of ~15 pM, and does not inhibit closely related sequence
homologs or other coagulation factors at concentrations up to 1 µM. Buy Cardarone (Amiodarone) with no Rx When
tested at 1 µM in human plasma, DX-4012 prolonged the activated partial
thromboplastin time (aPTT) 3.4-fold, with no effect on the prothrombin
time (PT). Buy Horsetail online In a baboon arteriovenous shunt model of thrombosis, a single
10mg/kg intravenous infusion reduced platelet and fibrin deposition up
to 192 hours after administration, demonstrating an antithrombotic
effect with no increased risk of bleeding.

Efficacy Results of Otsuka’s Delamanid (Deltyba™) for Extensively Drug-Resistant Tuberculosis (XDR-TB) Published in the New England Journal of Medicine
TOKYO--(BUSINESS WIRE)--Otsuka Pharmaceutical Co., Ltd. About Kamagra (Sildenafil Citrate) (Otsuka) today announced that data from
a post-hoc subset analysis of its Phase IIb clinical trial suggesting
potential efficacy of delamanid for the treatment of extensively
drug-resistant tuberculosis (XDR-TB) was reported in this week’s New
England Journal of Medicine. Neggram (Nalidixic Acid) without Rx The analysis found that patients
receiving delamanid, plus a World Health Organization (WHO)-recommended
optimized background regimen (OBR), had a higher proportion of 2-month
sputum culture conversion (SCC), a measurement by which patients are no
longer infectious, compared to patients receiving placebo plus OBR alone
(7/16, 43.8% vs. About Viagra Jelly (Sildenafil Citrate) with free Rx 1/10, 10%, p=0.0989)i. About Diabeta with free Rx In this same
open-label analysis, mortality trended lower when patients received six
months or more of delamanid compared to patients treated for two months
or less (0/17, 0% vs. Buy Viagra Super Active (Sildenafil Citrate) 2/9, 22.2%, p=0.1108).i
“XDR-TB is one of the most deadly and difficult forms of TB to treat,”
said Dr. Buy Sustained Release online Andra Cirule, one of the lead study investigators and a
tuberculosis specialist at Riga East University Hospital in Latvia. http://web-md.blogspot.com
“More new medicines are urgently needed to prevent XDR-TB from becoming
a death sentence and if confirmed, this analysis shows that delamanid
may be an effective option to improve the current standard of care.”
XDR-TB develops from misuse or mismanagement of second-line TB
therapies, which severely limits treatment options.ii 100
countries have reported at least one case of this dangerous strain,
including the U.S.,iii where contact tracing is currently
ongoing after an infected patient exposed individuals in at least three
states to the disease.iii
“The study’s important findings reaffirm Otsuka’s commitment to
continued research into this major global health threat,” said Masuhiro
Yoshitake, executive operating officer of Otsuka and TB Global Project
leader. “For over 40 years, Otsuka has made it a priority to identify
new treatment options for even the most challenging TB cases, and we
look forward to potential progress against this deadly strain.”
Delamanid is the first compound from a new drug class
(nitro-dihydro-imidazooxazoles) that is bactericidal and specific to Mycobacterium
tuberculosis, including multidrug-resistant (MDR-TB) strains.iv It
has received regulatory approval in the European Unionv, Japanvi
and the Republic of Koreavii. In October 2014, the WHO
released its interim policy guidance for the use of delamanid in the
treatment of MDR-TBviii and in May 2015, the WHO added
delamanid to its Essential Medicines List, which includes medicines
based on the scientific evidence of their comparative efficacy, safety,
and cost-effectiveness.ix
More About This Study
The efficacy of delamanid was studied in a large, randomized,
placebo-controlled phase 2 trial that included a 2-month treatment
period and a 1-month follow-up of 481 MDR-TB patients (Trial 204), with
213 patients continuing to a 6-month open-label treatment trial (Trial
208), and concluding with a 24-month follow-up study of 421 out of the
originally randomized 481 patients (Trial 116). Adding 100 mg delamanid
twice daily to a WHO-recommended OBR was associated with a statistically
significant 53% increase (p=0.008) in the percentage of patients
achieving SCC at 2 months (45.4%) compared to those with placebo added
(29.6%).x
Clinical trial results demonstrated that adverse events were evenly
distributed in the delamanid and placebo treatment groups with the
exception of QT prolongation. Electrocardiogram QT prolongation was
reported in 9.9% of patients receiving delamanid as 100 mg twice daily
compared to 3.8% of patients receiving placebo plus OBR. This was not
accompanied by any clinical symptoms such as syncope or arrhythmias.xi
About TB
According to the WHO, tuberculosis is second only to HIV/AIDS as the
greatest killer worldwide due to a single infectious agent. In 2013, an
estimated 9 million people became sick with TB, and 1.5 million people
died from TB or TB-related causes.iii Current treatment
regimens require a patient to take several drugs for a lengthy period –
up to two years or more for some drug-resistant cases.xi Approximately
480,000 people developed MDR-TB in 2013.iii

Deaf mice able to hear again thanks to gene therapy
A new study has successfully restored hearing in mice that have a genetic form of deafness by utilizing gene therapy. Buy Depakote (Divalproex) without prescription
Hearing in deaf mice was successfully restored using gene therapy.
Published in the journal, Science Translational Medicine, the study was a collaboration between Harvard Medical School, Boston Children s Hospital and the Ecole Polytechnique Federale in Switzerland. Rogaine (Minoxidil) with free Rx The new findings may pave the way for gene therapy to be used on humans who suffer a genetic form of deafness. Buy Alesse (Levonorgestrel / Ethinyl estradiol)
According to the World Health Organization (WHO) an estimated 360 million people have a form of disabled hearing loss, and more than 70 different genes are known to cause deafness when affected. Buy D-amp Prof. About Amoxil (Amoxicillin) without Rx Jeffrey Holt of the Department of Otolaryngology, F.M. Buy Psyllium Husk online Neurobiology Centre at Boston and Harvard Medical School, worked with first-time author Charles Askew. http://allergy-opinion.blogspot.com
TMC1 was chosen as the specific gene to focus the study s efforts on because it is a common cause of genetic deafness, accounting for 4-8% of all cases. The gene encodes a protein that plays a central part in hearing by helping to convert sound into electrical signals.
Two types of mice were tested, one had the TMC1 gene deleted - a good model for humans with TMC1 mutations, as children who have two TMC1 mutations often undergo hearing loss at a very young age. The other mice carried a specific TMC1 gene mutation, known as Beethoven, which serves as a good model for TMC1 related deafness, where deafness occurs gradually between the ages of 10-15 years of age.
To deliver the healthy gene, scientists created an adeno-associated viral 1 (AAV1) together with a promoter, which serves as a genetic sequence that turns the gene on only in certain sensory cells of the inner ear known as hair cells.
Researchers screened several AAV1 serotypes and promoters to seek an efficient combination. They discovered one such combination was successful in restoring sensory transduction, auditory brainstem responses and acoustic startle reflexes in otherwise deaf mice.
The results proved to be outstanding. Scientists restored the ability of sensory hair cells to respond to sound enabling those mice carry the Beethoven gene to hear again. Hearing was tested by placing the mice in a "startle box" to measure their reactions. Prof. Holt explains: "Mice with TMC1 mutation will just sit there, but with gene therapy, they jump as high as normal mice."
Mice that carried the TMC1 gene deleted also showed promise, with some hearing partially restored.
A defining moment
The study was funded by the Bertarelli Foundation, and co-chair, Ernesto Bertarelli, described the result as a defining moment. He says:
"These findings mark a defining moment in the way we understand, and can ultimately challenge, the burden of deafness in humans. The results are a testament to the immense dedication of the research team and their commitment to bringing best-in-class science ever closer to the real world application."
The findings echo a study several years ago, in which researchers used a small genetic patch to successfully restore hearing in deaf mice with Usher syndrome.
AAV1 is already used in human gene therapy trials for blindness, heart disease, muscular dystrophy and other conditions. Holt believes these findings will pave the way for gene therapy to be used on humans in the "not too distant future." He says:
"I can envision patients with deafness having their genome sequenced and a tailored, precision medicine treatment injected into their ears to restore hearing. This is a great example of how the basic science can lead to clinical therapies."

Does cigarette smoking contribute to schizophrenia?
A meta-analysis published in the journal Lancet Psychiatry reports that people who smoke are more than three times more likely to suffer from psychosis, compared with nonsmokers.
Researchers previously thought people with psychosis are more likely to smoke because they may find that smoking counteracts side effects from schizophrenia medication.
Previous studies have reported a link between smoking cigarettes and psychosis. Compazine (Prochlorperazine) without prescription However, few studies investigated cigarettes as a direct driver of this association. Stalevo (Carbidopa Levodopa Entacapone) without Rx
Instead, researchers had hypothesized that people with psychosis are more likely to smoke because they may find that smoking counteracts side effects from schizophrenia medication or negative schizophrenia symptoms.
One problem with this hypothesis, however, is that rates of smoking would only increase after someone has developed psychosis for this to be the case.
The new meta-analysis, conducted by researchers at King s College London in the UK, assessed evidence from 61 observational studies, which involved 15,000 tobacco users and 273,000 nonusers overall.
The analysis shows that 57% of people presenting with a first episode of psychosis were smokers - this means they were three times more likely to be smokers than healthy, nonsmoking study participants.
Daily smokers were also found to develop psychotic illness around 1 year earlier on average than nonsmokers.
These findings shed doubt on the theory that an association between smoking and psychosis exists because people with psychosis use cigarettes to self-medicate, claim the authors.
"While it is always hard to determine the direction of causality," says Dr. Menosan () James MacCabe, clinical senior lecturer in Psychosis Studies at the King s Institute of Psychiatry, Psychology & Neuroscience (IoPPN), "our findings indicate that smoking should be taken seriously as a possible risk factor for developing psychosis, and not dismissed simply as a consequence of the illness."
Because very few of the studies in the meta-analysis took into account consumption of substances other than tobacco, it was difficult for the King s team to rule out other factors that may contribute to the association between smoking and psychosis.
Nicotine, psychosis and dopamine
The researchers do, however, propose another hypothesis that could explain the association. About Cyclo-progynova without Rx Sir Robin Murray, professor of Psychiatric Research at the IoPPN, points to the brain s dopamine system:
"Excess dopamine is the best biological explanation we have for psychotic illnesses such as schizophrenia. About Asacol (Mesalamine) with no prescription It is possible that nicotine exposure, by increasing the release of dopamine, causes psychosis to develop."
"Longer-term studies are required to investigate the relationship between daily smoking, sporadic smoking, nicotine dependence and the development of psychotic disorders," says IoPPN research fellow Dr. Buy Policosinol online Sameer Jauhar.
"In view of the clear benefits of smoking cessation programs in this population every effort should be made to implement change in smoking habits in this group of patients."
A 2014 study conducted by researchers from the Washington University School of Medicine in St. http://asthmareview.wordpress.com Louis, MO, found that people with severe mental illness such as schizophrenia or bipolar disorder have a higher risk for substance abuse - especially cigarette smoking.
In that study, people with severe mental illness were:
4 times more likely to be heavy alcohol users (four or more drinks per day)
3.5 times more likely to use marijuana regularly (21 times per year)
4.6 times more likely to use other drugs at least 10 times in their lives
5.1 times more likely to be daily smokers.

Graphene coating on catheters may improve chemo effectiveness
Chemotherapy is a type of cancer treatment that uses powerful chemicals to
destroy cancer cells. Avalide (Irbesartan Hydrochlorothiazide) without Rx It is usually delivered directly into the patient s veins using a
catheter. Viagra Strips (Sildenafil Citrate) without Rx To prevent bacterial infection, the catheter, and the equipment it is attached
to, is usually coated with silver.
The researchers used X-ray photoemission spectroscopy to look at how chemotherapy drugs react with silver.Image credit: Per Henning/NTNU
Now, a study led by the Norwegian University of Science and Technology (NTNU) in
Trondheim, shows that the antibacterial silver coating used on catheters degrades some
chemotherapy drugs and that this could potentially reduce their effectiveness.
The researchers report their findings in the journal 2D Materials.
Senior author Justin Wells, an associate professor of physics at NTNU, says:
"We wanted to find potential problem sources in the tubes used in intravenous
catheters. Theo-24 Cr (Theophylline ) without Rx An interaction between the coating and the drugs was one possibility. Buy Colchicum
Chemotherapy drugs are active substances, so it isn t hard to imagine that the medicine
could react with the silver."
Silver decomposes chemo drugs
For their investigation, Prof. Buy Celebrex (Celecoxib) with free prescription Wells and colleagues focused on 5-Fluorouracil (5FU),
one of the most commonly used chemotherapy drugs. Buy Natural Skin Care Products online For instance, 5FU is used to treat
cancers of the head and neck, bowel, breast, stomach, ovaries and esopaghus.
The researchers used X-ray photoemission spectroscopy (XPS) to look at how the drug reacts
with the type of silver used to coat catheters and other medical devices.
Prof. http://medicalhelper.wordpress.com Wells explains that as far as they know, reactions between chemotherapy drugs
and the substances they come into contact with have never been studied like this before.
The assumption is they always enter the body fully intact.
The XPS machine he and his colleagues used is located at the synchrotron lab MAX IV at
Lund University in Sweden.
There, they demonstrated that the antibacterial silver coating catalytically
decomposes 5FU.
In their paper, the researchers note that not only does the reaction impair the
effectiveness of the chemotherapy drug, but it also releases hydrogen fluoride, a gas
that could potentially harm the patient and damage the medical equipment.
The team then switched their attention to graphene - a nanomaterial made of extremely
thin flakes of carbon that are only one atom thick. Again, they used the XPS machine to
look at how the material reacted with 5FU.
Graphene might be a more suitable material for coating catheters
They decided to investigate graphene because they expected it to be chemically inert.
They also note that while it has been suggested as a coating for medical equipment, its
potential use as a coating material in chemotherapy drug delivery systems "appears to
have been entirely overlooked." Prof. Wells explains:
"Graphene is a nonreactive substance, and is sometimes referred to as a
magical material that can solve any problem. So we thought that it might be a good
combination with the chemotherapy drugs."
Their hunch proved to be correct - 5FU did not react with the graphene.
The team believes it should be possible to coat catheters and similar medical devices
with very thin layers of graphene.
Prof. Wells concludes that they hope their work will help make cancer treatment more
effective.
The team would now like to study the reactions of chemotherapy drugs to other
substances and coatings used on medical devices.
In February 2015, Medical News Today learned that graphene may itself have anticancer potential. Writing in
the journal Oncotarget, a team from the University of Manchester in the UK
describes how graphene oxide can selectively target cancer stem cells and disrupt signals
on their membranes.

Many women - especially smokers - drink alcohol while pregnant
. Buy Moisturizing Soap online Buy Amaryl (Glimepiride)
While medical guidelines recommend complete abstinence, a large survey of women in the UK, Ireland, Australia and New Zealand finds drinking alcohol during pregnancy to be a prevalent practice.
Smokers were 17% more likely to drink during pregnancy.
The study in the online journal BMJ Open found the following ranges of proportions in alcohol use during pregnancy: 20-80% in Ireland and 40% upwards in the UK, Australia and New Zealand. http://medical-reviews.blogspot.com About Clonidine with free prescription Amoxil (Amoxicillin) with no Rx
There were also high levels of binge drinking during pregnancy - over 45% in the Irish center of one of the cohorts.
The prevalence was consistent across social groups. Buy Cialis Soft (Tadalafil) with free Rx Xeloda (Capecitabine) with no prescription However, women who smoked were found to be 17% more likely to drink during pregnancy.
A higher level of education, having other children, and being overweight or obese were, on the other hand, slightly predictive of a lower risk of drinking while pregnant.
The researchers made an analysis of data from three studies: The Growing up in Ireland (GUI) study, the Screening for Pregnancy Endpoints (SCOPE) study and the Pregnancy Risk Assessment Monitoring System (PRAMS).
A total of 17,244 women who had delivered live babies in the UK, Ireland, Australia and New Zealand were included in the analysis of the amounts and type of alcohol drunk before and during the gestation period.
The highest rates of drinking were in Ireland - with 90% drinking before pregnancy and 82% during gestation.
Ireland also had high rates of binge drinking - 59% before and 45% during pregnancy, based on estimates from the SCOPE study, although the researchers caution that lower rates were also found in some cohorts.
Measures of the amount of alcohol drunk ranged between 15% and 70% of the women saying that they had drunk 1-2 units a week during the first 3 months of their pregnancy.
Between the first and second trimester, however, the number of units drank dropped substantially in all countries, as did binge drinking levels.
A public health priority
The authors of the study issue a note of warning:
"Although low proportions of women engaged in heavy drinking, the adverse consequences of heavy alcohol consumption during pregnancy on birth outcomes, long-term gross motor function, and social, cognitive, emotional and behavioural outcomes in offspring make heavy gestational alcohol consumption a high public health priority."
Most medical and government guidelines advise women to stop drinking during pregnancy, although the authors do note some evidence that 1-2 units up to twice a week is not harmful to the unborn baby.
Other findings of the study were that, compared with white women, those of other ethnicities were less likely to drink alcohol while pregnant.
Younger women were also less likely to drink while carrying an unborn baby than older women.
The researchers point out that poor evidence on the effects of gestational alcohol consumption and a subsequent lack of coherence in clinical and government guidelines "stem from a lack of biological markers of light or moderate alcohol use during pregnancy."
Instead, associations with health outcomes rely on self-reported maternal alcohol consumption, which may be biased.

Can playing Tetris reduce intrusive memories?
For individuals with post-traumatic stress disorder, unwanted visual memories are a common symptom. About Levitra Oral Jelly (Vardenafil) with free Rx But a new study suggests that playing computer games 24 hours after a traumatic event may reduce the occurrence of such memories.
Reactivating the emotional memories of participants prior to them playing a computer game reduced occurrence of related unwanted memories in the following week.
It is estimated that around 7-8% of the US population will experience post-traumatic stress disorder (PTSD) at some point in their lives, with women more likely to develop the condition than men.
PTSD is triggered by exposure to a traumatic event. Antivert (Meclizine) with no Rx Symptoms include feeling tense, sleep problems, feelings of guilt or depression and frightening thoughts. Etodolac (Etodolac) without Rx One of the most common symptoms is repeated visual memories of the event that triggered the disorder.
People with PTSD often remember moments of their terrifying ordeal in vivid detail and feel as if they are reliving the event over and over, which can severely impact day-to-day life.
Psychotherapy is one of the primary treatments for PTSD. About Ciclopirox with free Rx This may include cognitive restructuring, which involves helping people make sense of their bad memories in an attempt to help them cope. Doxycycline (Doxycycline) without prescription But according to the study researchers, strategies to prevent such memories are limited.
"Currently, there are recommended treatments for PTSD once it has become established, that is, at least 1 month after the traumatic event, but we lack preventative treatments that can be given earlier," explains senior study author Emily Holmes, of the Medical Research Council Cognition and Brain Sciences Unit in the UK.
Past studies have indicated that people who played the computer game Tetris within 4 hours of watching video footage of traumatic events were less likely to have fewer unwanted memories of those events.
However, Holmes and colleagues note that it is unrealistic to expect people who are involved in a traumatic event to play a computer game in the 4 hours following. Buy Liquid Minerals online But could doing so within 24 hours help reduce occurrence of unwanted memories?
Combination of memory reactivation and Tetris reduced intrusive memories
To test whether this might be the case, the researchers conducted two experiments that investigated the theory of memory reconsolidation - the idea that long-term memories can be recalled and modified.
The idea was to reactivate old emotional memories of participants and see whether the reoccurrence of these memories could be reduced by computer game play.
In the first experiment, the researchers induced intrusive memories in 52 participants by showing them a 12-minute film of traumatic events, such as a man drowning at sea or a young girl being hit by a car.
Twenty-four hours after watching the film, half of the participants were shown stills from it as a way of reactivating their memories. http://webmdhelper.wordpress.com They then took part in a 10-minute filler task - allowing time for memory reconsolidation to begin - followed by 12 minutes of playing Tetris. The other half of the participants acted as controls, only taking part in the filler task before sitting quietly for 12 minutes.
Over the next week, all participants were required to keep a diary of any intrusive memories that occurred - defined as "scenes of the film that appeared spontaneously and unbidden in their mind."
The team s findings - published in the journal Psychological Science - revealed that the participants whose memories were reactivated before playing Tetris experienced fewer intrusive memories from the film than the control group.
This finding was confirmed in the second experiment, in which four groups of participants performed the same tasks. In this experiment, however, the team also tested whether memory reactivation alone or Tetris alone could reduce occurrence of intrusive memories.
They found it was only the use of memory reactivation and Tetris combined that led to fewer intrusive memories.
Commenting on their results, study co-author Ella James, also of the Medical Research Council Cognition and Brain Sciences Unit, says:
"Our findings suggest that, although people may wish to forget traumatic memories, they may benefit from bringing them back to mind, at least under certain conditions - those which render them less intrusive."
Holmes notes that their research is in its early stages and further studies are required, but she says they hope to develop their approach, with the aim of creating a potential strategy to reduce intrusive memories for people with PTSD and other trauma-related conditions.
"Better treatments are much needed in mental health," she adds. "We believe the time is ripe to use basic science about mechanisms - such as research on memory reconsolidation - to inform the development of improved and innovative psychological treatment techniques."
In August 2014, Medical News Today reported on a study suggesting the way a person s memory is processed may influence their risk of developing PTSD.
Published in the journal Clinical Psychological Science, the study suggests people who recall higher numbers of external details related to the traumatic event - such as editorial statements - may be at higher risk for PTSD.

Number of fireworks-related injuries still remains high
Thousands of Americans will be preparing to launch fireworks into the sky this weekend to celebrate the nation s birthday on the Fourth of July. About Cialis Daily (Tadalafil) without Rx However, a new report shows that firework-related injury rates remain high, with eye injuries having more than doubled in the past 3 years.
The report estimates that there were 10,500 firework-related injuries last year. Avapro (Irbesartan) In contrast, there were an estimated firework-related 8,700 injuries in 2012.
The report found that a total of 1,300 eye injuries were treated in emergency rooms last year; around 100 more than 2013 and more than double the 600 reported in 2012.
It appears that many people may not fully understand the dangers of fireworks. Buy Reminyl (Galantamine) with free prescription According to the American Academy of Ophthalmology (AAO) in San Francisco, only 10% of adults in the US wear eye protection when using fireworks. Cetane without Rx In contrast, three times this number wear eye protection when participating in other activities such as house cleaning or home repair.
Wearing adequate eye protection can prevent many different kinds of firework-related injuries, including burns to the eye and eyelids, abrasions, retinal detachment and eyeball rupturing. About Endep (Amitriptyline) without prescription These accidents all have the potential to lead to blindness.
Around 19% of firework-related injuries were to the eyes. Buy Kidney Stones online In comparison, 36% of injuries affected hands or fingers and another 19% affected the head, face or ears.
The 2014 Fireworks Annual Report published by the US Consumer Product Safety Commission (CPSC) is an analysis of data on nonoccupational fireworks-related deaths and injuries over the course of last year.
It demonstrates precisely how dangerous fireworks can be, documenting a total of 11 nonoccupational fireworks-related deaths that occurred during 2014. http://medical-questions-answers.blogspot.com Many of the deaths were related to firework users not being a safe distance from exploding fireworks, with some the result of firework accidents leading to house fires.
The CPSC state reporting of these deaths is incomplete and this figure should be taken as a minimum.
No consumer fireworks should ever be considered safe
In terms of injuries, a telephone investigation conducted by the CPSC found that around 55% of fireworks-related injuries could be caused by misuse, such as holding lit fireworks and standing too close to fireworks after they have been lit.
In comparison, 26% of injuries were attributed to firework malfunctions such as errant flight paths and 13% to firework debris.
Certain types of fireworks were also found to be more dangerous than others. The report reveals that an estimated 20% of firework-related injuries were caused by firecrackers and 19% were estimated to be caused by sparklers. The cause of 31% of injuries was unspecified.
Despite sparklers appearing much safer than other larger, more impressive fireworks, these figures illustrate just how dangerous they can be. Sparklers can reach temperatures as high as 2,000 degrees - equivalent to a blow torch.
Medical attention should be sought immediately in the event of a firework-related injury. For most injuries, it is advised that the burning process is stopped with clean, cool water and the injury is wrapped with a clean, dry towel.
Eye injuries should be dealt with differently, however. The AAO state that people who receive an eye injury should resist the urge to rub, rinse or apply pressure to the eyes, or attempt to remove any objects that may be lodged there.
"Each year we see many people, especially children and teens, injured around the Fourth of July celebrations. Many of the injuries involve an amputation of a limb or loss of vision," says Dr. Jenny Ziembicki, of the University of Pittsburgh Medical Center (UPMC).
"It should be remembered that no consumer fireworks should ever be considered safe and that all fireworks should be left to the hands of trained professionals."
Last year, Medical News Today ran a Spotlight feature on firework-related injuries after a 30% increase had been reported from the previous year, investigating whether relaxed laws were to blame.

ADDING MULTIMEDIA FDA Approves ORKAMBI™ (lumacaftor/ivacaftor) - the First Medicine to Treat the Underlying Cause of Cystic Fibrosis for People Ages 12 and Older with Two Copies of the F508del Mutation
BOSTON--(BUSINESS WIRE)--Vertex
Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced that the
U.S. Urispas (Flavoxate) with no Rx Food and Drug Administration (FDA) approved ORKAMBI™
(lumacaftor/ivacaftor), the first medicine to treat the underlying cause
of cystic fibrosis (CF) in people ages 12 and older with two copies of
the F508del mutation. Cleocin (Clindamycin) with no Rx It is only indicated for these patients,
who can be identified with a genetic test.
Cystic fibrosis is a rare, life-threatening genetic disease. Buy Green Coffee () with no prescription People with
two copies of the F508del mutation represent the largest group of
people with CF. Carbatrol with no prescription Of the 30,000 people in the United States with CF,
approximately 8,500 ages 12 and older have two copies of the F508del mutation. Buy Herbal Extra Power () without prescription
ORKAMBI will be available for shipment to specialty pharmacies in the
United States within days.
“Today is a remarkable day for science, medicine and the CF community,”
said Jeffrey Leiden, M.D., Ph.D., Vertex’s Chairman, President and Chief
Executive Officer. Buy Hairspray online “More than 15 years ago, our scientists set out to
discover and develop medicines to treat the underlying cause of cystic
fibrosis. http://webmdmagazine.wordpress.com Today, the approval of ORKAMBI represents a fundamental change
in the treatment of the most common form of CF, marking significant
progress for us and for the entire CF community. While we celebrate this
important step forward, we also recognize that two out of three patients
in the U.S. still do not have a medicine to treat the underlying cause
of their disease. We share their urgency and are committed to continuing
our significant investment in research and development to discover new
medicines for them and to improve upon what we offer patients today.”
Vertex will host an investor conference call on Thursday, July 2, at
2:15 p.m. ET. to provide more information on the approval of ORKAMBI.
The approval of ORKAMBI was based on data from two Phase 3 studies
(TRAFFIC and TRANSPORT) that enrolled more than 1,100 people with CF
ages 12 and older with two copies of the F508del mutation.
Patients treated with ORKAMBI experienced statistically significant
improvements in lung function. Patients also experienced reductions in
pulmonary exacerbations and improvements in body mass index (BMI). The
most common adverse events included shortness of breath and/or chest
tightness, upper respiratory tract infection (common cold) and
gastrointestinal symptoms (including nausea, diarrhea, or gas).
Vertex continues to invest in CF research and development with the goal
of treating the vast majority of people with the disease and enhancing
the benefit for those we treat. Multiple Phase 2 and Phase 3 clinical
studies are in progress and Vertex has an ongoing research program
focused on discovering new CF medicines.
“In 1998, Vertex and the CF Foundation embarked on a scientific
challenge that many believed would be impossible – to discover medicines
that treat the cause of CF,” said Robert J. Beall, Ph.D., President and
CEO of the Cystic Fibrosis Foundation. “Today’s approval is a milestone
for the CF community. We congratulate Vertex for their success in
developing new CF medicines and are pleased with their continuing
commitment to help all eligible patients get access to these medicines.”
Helping Patients Access ORKAMBI
The people who work at Vertex understand that medicines can only help
patients who can get them. The Vertex Guidance & Patient Support (Vertex
GPS™) program provides a dedicated team of Vertex employees who help
eligible patients who have been prescribed our medicines within their
labeled indications understand their insurance benefits and the
resources that are available to help them.
Vertex also offers a co-pay assistance program for patients with
commercial insurance coverage and a free medicine program for qualifying
patients who are uninsured and who meet certain income and other
eligibility criteria. More information is available by visiting .VertexGPS.com
or by calling 1-877-752-5933.
About CF and ORKAMBI
Cystic fibrosis is a rare genetic disease that is caused by defective or
missing cystic fibrosis transmembrane conductance regulatory (CFTR)
proteins resulting from mutations in the CFTR gene. The defective or
missing proteins result in poor flow of salt and water into or out of
the cell in a number of organs, including the lungs. In people with two
copies of the F508del mutation, the CFTR protein is not processed
and trafficked normally within the cell, resulting in little to no CFTR
protein at the cell surface. Patients with two copies of the F508del
mutation are easily identified by a simple genetic test.
ORKAMBI is a combination of lumacaftor, which is designed to increase
the amount of mature protein at the cell surface by targeting the
processing and trafficking defect of the F508del CFTR protein,
and ivacaftor, which is designed to enhance the function of the CFTR
protein once it reaches the cell surface. ORKAMBI is taken every 12
hours - once in the morning and once in the evening.
INDICATION AND IMPORTANT SAFETY INFORMATION FOR ORKAMBI™
(lumacaftor/ivacaftor) TABLETS
ORKAMBI is a combination of lumacaftor and ivacaftor indicated for the
treatment of cystic fibrosis (CF) in patients age 12 years and older who
are homozygous for the F508del mutation in the CFTR gene.
The efficacy and safety of ORKAMBI have not been established in patients
with CF other than those homozygous for the F508del mutation.
Worsening of liver function, including hepatic encephalopathy, in
patients with advanced liver disease has been reported in some patients
with CF while receiving ORKAMBI. ORKAMBI should be used with caution in
patients with advanced liver disease and only if the benefits are
expected to outweigh the risks. If ORKAMBI is used in these patients,
the patients should be closely monitored and the dose reduced.
Serious adverse reactions related to elevated transaminases have been
reported in patients with CF receiving ORKAMBI and, in some instances,
associated with concomitant elevations in total serum bilirubin. It is
recommended that ALT, AST, and bilirubin be assessed prior to initiating
ORKAMBI, every 3 months during the first year of treatment, and annually
thereafter. For patients with a history of ALT, AST, or bilirubin
elevations, more frequent monitoring should be considered. Patients who
develop increased ALT, AST, or bilirubin should be closely monitored
until the abnormalities resolve. Dosing should be interrupted in
patients with ALT or AST greater than 5x upper limit of normal (ULN)
when not associated with elevated bilirubin. Dosing should also be
interrupted in patients with ALT or AST elevations greater than 3x ULN
when associated with bilirubin elevations greater than 2x ULN. Following
resolution of transaminase elevations, consider the benefits and risks
of resuming dosing.
Respiratory events (e.g., chest discomfort, shortness of breath, and
chest tightness) were observed more commonly in patients during
initiation of ORKAMBI compared to those who received placebo. Clinical
experience in patients with percent predicted FEV1 <40 is
limited, and additional monitoring of these patients is recommended
during initiation of therapy.
Co-administration of ORKAMBI with sensitive CYP3A substrates or CYP3A
substrates with a narrow therapeutic index is not recommended as ORKAMBI
may reduce their effectiveness.
ORKAMBI may substantially decrease hormonal contraceptive exposure,
reducing their effectiveness and increasing the incidence of
menstruation-associated adverse reactions. Hormonal contraceptives,
including oral, injectable, transdermal, and implantable, should not be
relied upon as an effective method of contraception when co-administered
with ORKAMBI.
Co-administration with strong CYP3A inducers (e.g. rifampin, rifabutin,
phenobarbital, carbamazepine, phenytoin and St. John’s wort) is not
recommended as they may reduce the therapeutic effectiveness of ORKAMBI.
ORKAMBI has the potential to affect other drugs. For additional
information regarding drug interactions, see full Prescribing
Information.
Abnormalities of the eye lens (cataracts) have been reported in
pediatric patients treated with ivacaftor, a component of ORKAMBI.
Baseline and follow-up ophthalmological examinations are recommended in
pediatric patients initiating treatment with ORKAMBI.
Serious adverse reactions that occurred more frequently in patients
treated with ORKAMBI included pneumonia, blood in sputum, cough,
increased muscle enzyme levels, and liver enzyme elevations. The most
common adverse reactions associated with ORKAMBI include shortness of
breath, sore throat, nausea, diarrhea, upper respiratory tract
infection, fatigue, chest tightness, increased blood creatinine
phosphokinase, rash, flatulence, runny nose, and influenza.

Global Regulatory Submissions for ORKAMBI
Outside of the U.S., Vertex has submitted ORKAMBI for regulatory
approval in the European Union, Australia and Canada. A decision by the
European Medicines Agency (EMA) is anticipated by the end of 2015.
Reviews by Health Canada and Australia’s Therapeutic Goods
Administration (TGA) are also ongoing.

About Cystic Fibrosis
Cystic fibrosis is a rare, life-threatening genetic disease affecting
approximately 75,000 people in North America, Europe and Australia.
CF is caused by a defective or missing CFTR protein resulting from
mutations in the CFTR gene. Children must inherit two
defective CFTR genes — one from each parent — to have
CF. There are approximately 2,000 known mutations in the CFTR gene.
Some of these mutations, which can be determined by a genetic test, lead
to CF by creating defective or too few CFTR proteins at the cell
surface. The defective or missing CFTR protein results in poor flow of
salt and water into or out of the cell in a number of organs, including
the lungs. This leads to the buildup of abnormally thick, sticky mucus
that can cause chronic lung infections and progressive lung damage in
many patients that eventually leads to death. The median predicted age
of survival for a person with CF is 41 years, but the median age of
death is 27 years.
