Lyme Disease Symptoms From Hospitals
Published on Apr 13 2010, in the categories: Early Lyme Disease
The infection with Borrelia (B) burgdorferi (Lyme disease) is transmitted by ticks and endemic with outbreaks in North America, Europe and Asia. This mechanism explains the seasonality of the Lyme infestation. The clinical manifestations are focal onset, with the extension system: skin, heart, nervous systems are the most affected organs, often with sequential involvement.
The infection starts early, localized for the presence of migrant erythema, followed by a stage of dissemination in the following weeks; intermittent Lyme disease symptoms from hospitals may persist and lead to late manifestations observed on average within a year. An infected patient can go through all stages or otherwise not submit any.
The neurologic Lyme disease symptoms from hospitals manifested at the early stage (radicoloneurite, cranial neuropathies, meningitis, cerebral symptoms minors, myositis) or late stages (progressive encephalomyelitis, encephalopathy, axonal neuropathy). Among the cases from Europe and America there are many differences due to different genotypic species of B burgdorferi in the two continents. Lymphadenitis benign skin, the chronic atrophic acrodermatitis and progressive encephalomyelitis are in fact observed almost exclusively in Europe, as some Lyme disease viruses are not found in North America, are the probable cause.
There is currently a test in order to follow the activity of infection. The presence of serum reactivity alone is not sufficient to diagnose the Lyme disease in patients. There are several effective antibiotics, which allow a treatment of early, late manifestations respond partially to treatment. A vaccine is currently in phase II of therapeutic trials.
Against Lyme disease, transmitted by the bite of ticks, was effective and well tolerated in children Vaccine pharmaceutical company GSK. According to a U.S. study conducted about four young patients (aged 4-18 years), published in the journal, the vaccine consists of a surface protein of the bacterium "Borrelia burgdorferi, the OSPA.
Researchers at Tufts University School of Medicine in Boston have conducted a screening of patients who had received the vaccine (dose of 30mcg of OSPA) and placebo pills. A first booster immunization was administered after a month and the second after one year.
With regard to immunogenicity, the results were identical to those obtained in adult patients, and indeed all children vaccinated presented concentrations of antibodies to 1,400 more units (Seroprotection) compared with 90% of adults. Local reactions were observed on the area of administration as well as an increase of fever, headache, fatigue, joint pain.
A more powerful and effective antibiotics may soon be available. A new molecule, the M33 peptide, has been identified in the Department of Molecular Biology, University of Siena. The molecule would be able to stem infections otherwise resistant to antibiotics in common.
The study, completed by two different teams led by professors and Gian Maria Rossolini, coordinated by Dr. Luisa Bracci and Alexander Pines, is being published in the journal FASEB Journal.
Researchers of the University of Siena found that the M33 peptide fails to protect animals used as guinea pigs by a number of otherwise fatal infections because of their resistance to other antibiotics. The research is extraordinarily important, in the words of Professor Pines, because "the problem of multi-bacterial resistance to antibiotics to traditional antibiotics makes it increasingly ineffective therapy based on the classic traditional antibiotics.
The identification of a new antibiotic molecule, apparently able to treat serious infections and less tractable, is an immediate application for industrial development and possible exploitation of the molecule in question."

Early Lyme Disease Symptoms

What is Lyme disease?
Lyme disease (the name derives from the American citizen where the first case was described in 1975) is a bacterial infection that affects mainly the skin, joints, nervous system and internal organs.
It may manifest with symptoms sometimes severe, persistent and, if untreated, it assumes a chronic course.
How is this disease transmitted?
A cause is a bacterium of the family of spirochetes, which naturally develop within the wood mice. Other wildlife (such as hares, foxes, ungulates and birds) may occasionally host the bacterium and contribute to its spread within the forest.
Ticks (especially of the genus Ixodes, the most widespread in the mountain environment) are the main carrier of the disease. Sucking the blood of infected animals, they get infected with the spirochete and then, their subsequent bites can transmit this disease to new hosts.
Ticks can bite any and all warm-blooded creatures, including humans. The bite is not painful and, for this reason, it passes unnoticed. Once attached to the skin, the tick acts as a pump, sucking the blood and regurgitating it continuously: in this way, it can contaminate a huge amount of blood in a short time.
Eventually the tick drops onto the ground, to digest the blood and seek a new host.
The habitat of the tick
Ticks live on land, on the grass. They prefer temperate climates and areas with a higher humidity.
They are found mostly at the edge of the woods, in clearings at the base of the bushes and near water courses. They can rarely be found at altitudes above 1,500 meters.
Ticks bite from spring to late autumn, and we cannot even exclude the winter months. Not all ticks are infected and are threatening illness.
What are the early Lyme disease symptoms?
The most frequent and characteristic early Lyme disease symptoms include reddening of the skin (usually located in the area of the bite) which tends to grow slowly.
This lesion (characteristically shaped like a “bull’s-eye”) is called erythema migrans and it appears after a period of 4-60 days after the bite. On rare occasions, the infection comes with pain in the joints and problems with the nervous system.
How does the disease evolve?
After the first location on the skin, the bacteria is transmitted by ticks and can spread anywhere in the body. In this case, except from early Lyme disease symptoms, later symptoms can include: pain in the joints (arthritis); nervous system problems (meningitis, neuritis of cranial nerves, motor difficulties and loss of sensitivity, limb); problems with other internal organs (heart, eye, liver, kidney disorders of varying extent).
If left to progress, the disease tends to persistent infection and, after a period of years after inoculation of the bacterium, to determine permanent results.
How do I prevent this disease?
Since there is still no vaccine against the disease the best prevention is to take certain precautions and to avoid hiking in the woods or the bite of ticks.
The main preventive measures are:
-use clothes that cover as much as possible the body,
-try not to sit on the grass
-Wash thoroughly and ensure there are no ticks on your clothes and body,
-Remember that ticks are most active from April to November.
