Can Surgery Trigger Rare Muscle Disorder?

Posted 12 days ago by Drugs.com

WEDNESDAY, Nov. 23, 2016 – Patients who've recently undergone surgery – especially those with cancer or autoimmune diseases – experience slightly higher risks of developing a rare muscle disorder soon afterward, new research suggests. Evaluating 20 years of data, Mayo Clinic scientists found that 15 percent of patients who developed Guillain-Barre syndrome had undergone a surgical procedure in the prior eight weeks. Guillain-Barre is a rare syndrome affecting only about one in 100,000 people. Symptoms include increasing muscle weakness that sometimes leads to total paralysis, according to the U.S. National Institutes of Health. It can be fatal if it interferes with breathing. "I don't think patients for any reason should be dissuaded from undergoing a surgical procedure they need because of this [research]," said study author Dr. Sara Hocker. She is an associate professor of ... Read more

Zika Babies May Look Normal at Birth, Display Brain Defects Later: CDC

Posted 13 days ago by Drugs.com

TUESDAY, Nov. 22, 2016 – Babies exposed to the Zika virus in the womb can look normal at birth but later show signs of the devastating birth defect microcephaly and other brain abnormalities, researchers reported Tuesday. Scientists found that 13 infants in Brazil who were exposed to the mosquito-borne virus during gestation had normal head size as newborns, but subsequently experienced slower head growth. Eleven of these babies were diagnosed with microcephaly – an abnormally small head and brain – and other neurologic complications associated with Zika syndrome, the researchers reported. "Among infants of mothers exposed to Zika virus during pregnancy, the absence of microcephaly at birth does not rule out congenital Zika virus infection or the presence of Zika-related brain abnormalities," according to a news release from the U.S. Centers for Disease Control and Prevention. The ... Read more

Imaging Studies Shed Light on Zika's Effects

Posted 13 days ago by Drugs.com

TUESDAY, Nov. 22, 2016 – More details on how the Zika virus affects infants and adults will be presented to international researchers meeting in Chicago next week. Three studies scheduled for presentation at the annual meeting of the Radiological Society of North America attempt to shed light on the mosquito-borne virus that's linked to severe birth defects in babies. Most cases to date have occurred in Latin American countries. In one study, researchers used CT imaging to examine the central nervous system of 16 newborns whose mothers were infected with Zika during pregnancy. The babies were found to have a number of brain abnormalities. "Our study proves that Zika virus infection can cause congenital brain damage in babies with and without microcephaly," study author Dr. Natacha Calheiros de Lima Petribu said in a society news release. She's with the department of radiology at Barao ... Read more

Congress Agrees to More Zika Funding: Reports

Posted 28 Sep 2016 by Drugs.com

WEDNESDAY, Sept. 29, 2016 – Long-delayed funding to combat the Zika virus is included in an emergency spending bill designed to keep the U.S. government running through mid-December, according to published reports on Wednesday. The bill would provide $1.1 billion to combat the Zika virus and develop a vaccine and improved tests to detect it, the Associated Press reported. Zika, which is primarily transmitted by mosquitoes, can cause severe birth defects. President Barack Obama in February asked Congress for $1.9 billion in emergency spending to fight Zika. The debate over additional Zika funding had pitted Republicans against Democrats. Republicans were opposed to allowing some of the funding to go to Planned Parenthood in Puerto Rico because of that group's connection to abortion services. But Republicans dropped their opposition earlier this month. Puerto Rico has been hit hard by ... Read more

Hurdles Ahead for Zika Vaccine: Experts

Posted 28 Sep 2016 by Drugs.com

WEDNESDAY, Sept. 28, 2016 – Work is progressing on developing a vaccine that can thwart the Zika virus, but it will take years to get one to market, experts warn. Two rival vaccines for Zika have the best chance of becoming available for field testing by early next year, said Dr. Anthony Fauci, director of the U.S. National Institute of Allergy and Infectious Diseases (NIAID). But testing the vaccines could become complicated if Zika does not reappear in the South American countries where it achieved epidemic proportions this year, Fauci wrote in a commentary published Sept. 29 in the New England Journal of Medicine. Testing could also be hampered if vaccine manufacturers aren't able to quickly make the millions of doses needed for field trials, added Dr. Stephen Thomas, an infectious diseases doctor at SUNY Upstate Medical University in Syracuse, N.Y. He also wrote a commentary in the ... Read more

3 Zika-Carrying Mosquitoes Found in Florida

Posted 1 Sep 2016 by Drugs.com

THURSDAY, Sept. 1, 2016 – Three mosquitoes in Miami Beach have tested positive for the Zika virus, a first in the continental United States, Florida health officials said Thursday. The mosquitoes were trapped in the same area where several cases of human infection have occurred, officials said. Ninety-five additional mosquito samples were subsequently tested for Zika and those mosquitoes were found to be Zika-free, the officials said. "This find [of the three mosquitoes] is disappointing, but not surprising," Commissioner of Agriculture Adam H. Putnam said in a news release. "Florida is among the best in the nation when it comes to mosquito surveillance and control, and this detection enables us to continue to effectively target our resources. Miami-Dade County, the City of Miami Beach, and state and federal partners will continue to work aggressively to prevent the spread of Zika," he ... Read more

Strong Link Emerges Between Zika, Spikes in Temporary Paralysis Cases

Posted 1 Sep 2016 by Drugs.com

THURSDAY, Sept. 1, 2016 – Where there's a Zika outbreak, there will likely be an accompanying increase in cases of Guillain-Barre syndrome, a new analysis shows. The latest finding strengthens a suspected link between infection with the mosquito-borne virus and the syndrome, which causes temporary paralysis in its victims. While the Zika virus doesn't pose a significant health threat to most people, it can cause a devastating birth defect called microcephaly, which leads to babies born with abnormally small heads and brains. The vast majority of Zika infections have been in Latin America and the Caribbean, with Brazil the epicenter. In areas where Zika outbreaks were reported, the researchers behind the new study documented a significant increase in Guillain-Barre cases. Guillain-Barre is known to be caused by infection with other viruses, the scientists noted in their report. More ... Read more

Florida Investigates 2 More Possible Cases of Zika Virus Local Transmission

Posted 28 Jul 2016 by Drugs.com

THURSDAY, July 28, 2016 – Florida health officials are investigating two more unexplained cases of Zika infection, bringing to four the number of cases that don't seem to be related to travel to countries where the virus is circulating. This suggests the possibility that local transmission of the mosquito-borne virus that has been linked to severe birth defects has begun, officials said. Zika infection poses significant risks to pregnant women, because it can cause the birth defect called microcephaly, which results in babies born with undersized heads and underdeveloped brains. But, the virus poses little threat to most other people, with about 80 percent of those infected never noticing any symptoms. The four cases are in the South Florida counties of Miami-Dade and Broward. "Evidence is mounting to suggest local transmission via mosquitoes is going on in South Florida," said Tom ... Read more

Zika May Be Linked to Autoimmune Brain Disorder, Study Says

Posted 11 Apr 2016 by Drugs.com

SUNDAY, April 10, 2016 – The Zika virus may be linked to yet another brain disorder, this one similar to multiple sclerosis, researchers report. The mosquito-borne virus is already suspected of causing a birth defect called microcephaly – characterized by an abnormally small head and brain – and a nervous system disorder called Guillain-Barre syndrome. Now, a new study reports a possible link between Zika and an autoimmune disorder known as acute disseminated encephalomyelitis (ADEM). In this disease, the immune system attacks the coating (myelin) around nerve fibers in the brain and spinal cord, much like multiple sclerosis. "Though our study is small, it may provide evidence that in this case the virus has different effects on the brain than those identified in current studies," said study author Dr. Maria Lucia Brito Ferreira, of Restoration Hospital, Recife, Brazil. The study ... Read more

Zika Poses Serious Threat to Puerto Rico: U.S. Health Officials

Posted 11 Mar 2016 by Drugs.com

THURSDAY, March 10, 2016 – U.S. health officials issued a worrisome assessment Thursday of the continued spread of the Zika virus, which is already suspected of causing thousands of birth defects in Brazil and has made inroads into Puerto Rico. Federal researchers are learning much about the virus. But the more they learn, the more they realize how much they don't know, Dr. Anthony Fauci, director of the U.S. National Institute of Allergy and Infectious Diseases, said during a morning media briefing. "Unfortunately, the more we learn the worse things seem to get," Fauci said. Researchers believe – but haven't proven – that the mosquito-transmitted Zika virus is linked to microcephaly, a birth defect that causes babies to be born with unusually small heads and underdeveloped brains. The virus is suspected of causing an epidemic that started last spring in Brazil, where there have been ... Read more

Another Neurological Disorder Tied to Zika

Posted 10 Mar 2016 by Drugs.com

WEDNESDAY, March 9, 2016 – The list of neurological disorders potentially associated with the Zika virus continues to grow, health officials reported Wednesday. Writing in the March 9 online edition of the New England Journal of Medicine, French researchers described the case of an unidentified 81-year-old man who had been in fine health before becoming feverish and then comatose while on a cruise in the South Pacific. An MRI scan and a test of spinal fluid indicated he was suffering from meningoencephalitis, an infection and swelling of the brain. The elderly cruise ship patient was admitted to an intensive care unit, where doctors were able to make a tentative diagnosis of Zika infection. Within several days, his condition began to improve without treatment, and 17 days after admission to the hospital he was removed from intensive care. By day 38, he was fully recovered, the ...

Zika Virus Tied to Rare Disorder That Can Cause Paralysis

Posted 1 Mar 2016 by Drugs.com

MONDAY, Feb. 29, 2016 – The Zika virus may cause Guillain-Barre syndrome, a disorder in which the body's immune system attacks part of the nervous system, new research suggests. Blood samples from 42 patients diagnosed with Guillain-Barre syndrome during a Zika virus outbreak in French Polynesia provide the first hard evidence that the mosquito-borne Zika virus might cause this severe neurological disorder, researchers said. "The risk for a Zika-infected individual of developing Guillain-Barre syndrome is small – less than [one] case per 1,000 Zika infections. So, individuals with acute Zika infection should not be greatly alarmed by the fear of developing of Guillain-Barre syndrome," said researcher Dr. Hugh Willison. He's a professor of neurology at the University of Glasgow College of Medical, Veterinary and Life Sciences in Scotland. The study can't prove cause-and-effect, but as ... Read more

In Fight Against Zika Virus, Officials Consider Genetically Modified Mosquitoes

Posted 16 Feb 2016 by Drugs.com

TUESDAY, Feb. 16, 2016 – As the Zika virus continues to spread fear and potentially devastating health problems throughout Latin America and the Caribbean, scientists are weighing the use of a controversial weapon – genetically modified mosquitoes. The mosquito-borne Zika virus is thought – but not proven – to be behind an epidemic of birth defects that leave newborns with very small heads and potential brain damage. The spread of the birth defects, called microcephaly, prompted the World Health Organization (WHO) last week to call the Zika outbreak a global emergency. The U.S. Centers for Disease Control and Prevention has said it does not expect the Zika virus to become widespread in the United States. But the CDC is recommending that pregnant women avoid those regions of Central and South America and the Caribbean where Zika virus has been identified and officials have described ... Read more

WHO: Neurological Disorder on the Rise in Zika Zones

Posted 15 Feb 2016 by Drugs.com

MONDAY, Feb. 15, 2016 – More cases of the rare but potentially devastating neurological disorder Guillain-Barre syndrome are appearing in some Latin American countries where the Zika virus is also present, according to the World Health Organization. The United Nations-affiliated health group said in a weekly report Saturday that Guillain-Barre syndrome, which can cause temporary paralysis, has been reported in Brazil, Colombia, El Salvador, Suriname and Venezuela, the Associated Press reported. But, the WHO added, the "cause of the increase in GBS (Guillain-Barre syndrome) incidence . . . remains unknown, especially as dengue, chikungunya and Zika virus have all been circulating simultaneously in the Americas." According to the U.S. National Institutes of Health, Guillain-Barre syndrome is a rare disorder that causes the immune system to attack the peripheral nervous system. As a ... Read more

'Swine Flu' Shot May Be Cleared of Guillain-Barre Charges

Posted 13 Jul 2011 by Drugs.com

WEDNESDAY, July 13 – A new European study finds that the supercharged vaccines used to fight the H1N1 epidemic in 2009 may not have boosted the risk for a disease known as Guillain-Barre syndrome after all. Guillain-Barre is a rare disorder, which causes a person's immune system to damage nerve cells, resulting in muscle weakness and even paralysis. In 1976, a vaccine used during a U.S. flu outbreak was linked to the disease, and the government halted vaccination. Debate has continued since then over whether vaccines in use could trigger the syndrome. In a study published July 13 in the journal BMJ, a consortium of researchers reported that the H1N1 vaccine posed little, if any, increased risk for the disease. "This study provides reassurance that adjuvanted pandemic influenza A (H1N1) 2009 vaccines did not increase the risk of Guillain-Barre syndrome substantially, if at all," they ... Read more
