Unless you.. enable Javascript.. , your ability to navigate and access the features of this website will be limited.. Cases of Dengue Fever Confirmed in Florida.. A number of cases of the mosquito-borne illness dengue fever have been reported in Florida recently, prompting a public health alert by the Florida Department of Health.. The cases were reported in the Martin, St.. Lucie, and Miami-Dade counties and, as of September 18.. th.. , the count is at 20.. Florida residents and anyone traveling to the counties where the recent cases have been reported are being encouraged to take preventive measures to avoid mosquito bites.. Anyone who experiences a high fever within two weeks of travel to an area where dengue fever is endemic, or travels to or lives where current cases have been reported, should consult their health care provider to determine if testing for dengue fever would be appropriate..

  • Title: Cases of Dengue Fever Confirmed in Florida
    Descriptive info: Search.. Help?.. Share this page:.. Was this page helpful?.. September 26, 2013.. A number of cases of the mosquito-borne illness dengue fever have been reported in Florida beginning at the end of August, prompting a public health alert by the Florida Department of Health.. The cases were reported in the Martin, the St.. Lucie, and the Miami-Dade counties and, as of September 18.. It is believed that these infections were all acquired locally.. Dengue fever is rare in the U.. , mostly seen among travelers returning from parts of the world where dengue is.. endemic.. , such as tropical and subtropical areas in Asia, South America, and the Caribbean.. However, small outbreaks have occurred in Texas, Hawaii, and Florida; in 2009-2010, a dengue outbreak in Key West was reported affecting 28 people.. Most dengue infections among U.. citizens occur in residents of Puerto Rico, the U.. Virgin Islands, Samoa and Guam.. Dengue fever is a.. viral.. infection transmitted to humans by mosquitoes.. There is no.. vaccine.. available or specific treatment other than for symptomatic relief.. Many infected individuals will not develop symptoms or will have only a mild illness..

  • Title: NGAL Shows Promise as Early Marker of Acute Kidney Injury
    Descriptive info: A.. kidney disease.. biomarker known as neutrophil gelatinase-associated lipocalin (NGAL) is gaining attention as an early, accurate indicator of acute kidney injury (AKI) following its successful use in a recent study.. The finding is noteworthy because it suggests that a blood test for NGAL can detect acute kidney damage earlier than currently used kidney function tests, such as.. serum creatinine.. AKI manifests as a sudden decrease in kidney function that, if left untreated, can sometimes cause permanent damage to the kidneys or become life-threatening.. People can develop AKI from a number of different causes, including trauma, burns, drug toxicity,.. sepsis.. , shock, or contrast dyes used during imaging procedures.. Factors that can increase the risk of developing AKI include.. diabetes.. ,.. high blood pressure.. heart disease.. lung disease.. , and pre-existing.. chronic.. NGAL is a.. protein.. that was originally found in.. neutrophils.. , a type of white blood cell.. It is also found in many other tissues in the body, including kidney cells.. Part of the reason NGAL is such a good indicator of AKI is that its levels rise rapidly in response to kidney injury, typically within 2-4 hours.. In contrast, the most commonly used markers of kidney function today, such as.. cystatin C.. , and creatinine, often do not change until well after damage or injury has already occurred.. Early detection of AKI is critical because injury occurs rapidly over a period of hours to days, unlike that seen with chronic kidney disease that develops over months to years.. Published in the September issue of the.. Clinical Journal of the American Society of Nephrology.. , the study evaluated more than 600 patients who were admitted to the hospital from the emergency department between March and November of 2008.. These 600 patients were selected from over 4,700 people and included those who had normal or only mildly abnormal kidney function at admission.. Selected study patients had conditions that would require at least two days of hospitalization, which would allow multiple blood samples to be collected and analyzed.. NGAL levels, cystatin C, and creatinine levels were measured in each of  ...   the first two days in the hospital, however, serum creatinine levels did not change significantly and did not identify patients with AKI.. The researchers concluded that adding NGAL evaluation to clinical criteria not only significantly improves prediction of AKI but also distinguishes AKI from reversible transient kidney dysfunction.. NGAL is one of several newer kidney function biomarkers being evaluated, and the results of the recent study suggest that it is an effective biomarker for predicting AKI.. Future research is needed to determine if predicting AKI with NGAL testing may lead to the prevention or reversal of the kidney damage through early detection and treatment.. One of the authors of the study holds a patent for the NGAL test, which has been approved in parts of Europe and Asia but is currently pending approval from the FDA in the U.. Additional independent studies need to be performed to more fully understand its clinical applications.. For example, since the current study did not look at patients with more severe acute kidney injury, or at patients with advanced chronic kidney injury, it is not clear how well the test would work in other groups of patients..

  • Title: Lyme Disease Cases Much Higher Than Thought, Studies Suggest
    Descriptive info: The Centers for Disease Control and Prevention (CDC) has released preliminary new data on the number of people in the United States who are diagnosed with.. Lyme disease.. each year.. The new estimate is 300,000 cases annually, not the 30,000 previously thought.. The larger estimate, based on data from three ongoing studies, was presented last month at the 2013 International Conference on Lyme Borreliosis and Other Tick-Borne Diseases.. According to the CDC, the higher estimate supports studies that go back as far as the 1990s showing that the actual number of Lyme disease cases is 3 to 12 times higher than the number of cases that are reported each year.. As stated by Paul Mead, MD, MPH, chief of epidemiology and surveillance for CDC's Lyme disease program in the CDC's August 19th press release, "We know that routine surveillance only gives us part of the picture, and that the true number of illnesses is much greater.. This new preliminary estimate confirms that Lyme disease is a tremendous public health problem in the United States, and clearly highlights the urgent need for prevention.. ".. The new, higher estimate does not mean that many Lyme disease cases go untreated, says the CDC, only that they may go unreported to state and federal public health laboratories.. However, low disease estimates from under-reporting can create an inaccurate picture of the scope of a public health problem such as this—especially when the.. incidence.. may be so much higher than previously thought.. Better estimates can help increase awareness of the issue, providing additional incentive for the general public, government, and medical community to focus on this disease and its prevention.. Lyme disease is an infection caused by.. Borrelia burgdorferi.. bacteria.. , which are carried by blacklegged ticks.. It is most common in the Midwest and Northeast U.. Thirteen states account for 96% of cases (see CDC's.. Lyme Disease Map.. ).. Infections generally occur in the spring and summer when ticks are  ...   diagnosis on a patient's symptoms and history of tick bite or exposure to an area with a high prevalence of Lyme disease.. However, not everyone infected with Lyme disease develops the bull's-eye rash or notices other more nonspecific symptoms.. Laboratory testing for people who do not have symptoms is not recommended by the CDC because it contributes to a high rate of.. false positives.. False positives on.. antibody tests for Lyme disease.. can also be caused by infections with other bacteria that are similar to.. B.. burgdorferi.. , such as the one that causes syphilis.. Therefore, positive or indeterminate test results should always be confirmed using another method.. False negatives.. can occur if testing is performed too soon, before the body has had time to produce.. to.. , which can take several weeks.. The CDC continues to analyze the data from the three studies prior to their completion.. Individuals, especially those in states with high rates of Lyme disease, can protect themselves by following.. steps recommended by the CDC.. , such as using repellent to ward off ticks, checking frequently for ticks and removing any attached ones quickly and correctly, and being aware of the symptoms of Lyme disease.. If you experience any symptoms, such as rash or fever, and have been in an area known to have infected ticks, consult your health care provider.. Lyme Disease Tests.. CDC: Lyme Disease..

  • Title: Parasite Cyclospora is Latest Culprit in Foodborne Illness Outbreak
    Descriptive info: Parasite.. Public health officials have been closely tracking a recent outbreak of cyclosporiasis, a type of intestinal infection caused by a single-celled.. parasite.. rare to the U.. The Centers for Disease Control and Prevention (CDC) first became aware of the outbreak on June 28 when two cases of cyclosporiasis in Iowa were detected by the State Hygienic Laboratory, Iowa's state public health laboratory.. Since then,.. infection has been reported in 22 states, including Arkansas, California, Connecticut, Florida, Georgia, Illinois, Iowa, Kansas, Louisiana, Minnesota, Missouri, Nebraska, New Jersey, New Hampshire, New York (including New York City), Ohio, South Dakota, Tennessee, Texas, Virginia, Wisconsin, and Wyoming.. See the latest case count and the states affected at the CDC.. Outbreak.. web page.. Although the CDC has not established whether all of the cases are part of the same outbreak, an investigation by the Food and Drug Administration (FDA) revealed that illnesses in Nebraska and Iowa have been linked to bags of salad mix produced by Taylor Farms de Mexico.. Teams of public health officials have since been dedicated to investigating the cause of infection in other states.. Typically, people contract cyclosporiasis by consuming food or water that is contaminated with the parasite.. Because.. must be passed in a bowel movement and allowed time to incubate before becoming infectious, person-to-person transmission rarely, if ever, occurs.. Symptoms usually develop about one week after ingesting the parasite.. Some people, however, do not experience any symptoms.. For those that do, symptoms may include watery diarrhea, loss of appetite, nausea, cramping, bloating, gas, fatigue, fever or other flu-like symptoms.. These can last, in some cases, over two weeks.. Though most people who are otherwise healthy will recover without treatment, a combination of antibiotics is typically prescribed.. The infection is usually not deadly, but if not treated, symptoms can persist several weeks to months and may even return after a period of subsiding.. Symptoms can be mimicked by other gastrointestinal infections and testing helps definitively diagnose a.. infection.. Testing involves collecting a stool sample and placing  ...   cautions that the parasite is particularly resilient and is not easily killed by routine disinfecting methods.. The best prevention is to avoid food and water sources that are known to be contaminated with stool.. Treatment of water with chlorine or iodine is not effective in killing.. In the Nebraska and Iowa cyclosporiasis cases, contaminated salad mixes were distributed to restaurants and grocery stores in the two states, and the FDA reported that four restaurants—including two large chains—received the tainted supply.. As of yet, no reported illnesses have been traced to bags purchased by consumers.. Taylor Farms has cooperated with FDA officials, agreeing to stop all shipments of prepackaged salad mix to the U.. (in addition to other fresh produce items) until further notice.. The first documented cases of.. infection were detected in Papua New Guinea in 1977.. Since the mid-1990s, cyclosporiasis outbreaks have been tied to imported fresh produce, such as the Guatemalan raspberries and snow peas and Peruvian mesclun lettuce and basil implicated in previous years.. Cyclosporiasis is.. to tropic and subtropic regions, and many of those in the U.. who develop the infection when it is unrelated to an outbreak have traveled to, and subsequently contracted it from, those areas..
