Rabies virus is the lyssavirus associated with rabies in bats and terrestrial mammals around the world depression k test wellbutrin 300mg generic. Other lyssaviruses have been identified in bats in Europe anxiety vomiting order wellbutrin 300mg fast delivery, Africa mood disorder clinic ucla order wellbutrin 300 mg otc, Asia and Australia depression symptoms in guinea pigs buy cheap wellbutrin. Rabies is transmitted from animal to animal through transfer of virus-contaminated saliva by bites or mucous-membrane exposures bipolar depression 5-htp purchase wellbutrin 300mg with amex. In Indiana anxiety 3 year old order generic wellbutrin, the North Central Skunk virus and numerous bat subtypes of rabies virus have been identified in the past. In 2014, 1,079 animals of various species were tested for rabies in Indiana, and 12 tested positive. Public Health Significance In humans, early symptoms of rabies infection are non-specific but may be similar to influenza (the flu) and may include headache, fever and malaise. As the disease rapidly progresses, symptoms include numbness/tingling at the site of the bite, anxiety, confusion, hallucinations, excessive salivation and difficulty swallowing. The virus infects the central nervous system, resulting in death, often within days of symptom onset. Rabies post-exposure prophylaxis is available in the form of immunoglobulin and vaccination. Treatment has not been shown to be effective if given after the development of clinical signs; the vaccine must be given before clinical signs develop. Although anyone can be at risk for rabies, people who work with rabies virus in research laboratories and vaccine production facilities are at the highest risk. Other groups at risk include veterinarians, animal control and wildlife officers, rehabilitation specialists and bat handlers. Epidemiology and Trends Rabies is a rare disease of humans in the United States; no human cases were reported in Indiana in 2014 or in the five-year reporting period from 2010-2014. Bats continued that trend in 2014, being the only animal species found positive: 12 bats tested positive in 2014 and 99 bats tested positive from 2010-2014. The last domestic animal to be infected was a horse in 2002 that was found to have a bat strain of rabies virus. The most recent human rabies case in Indiana was also infected with a bat strain of the virus.

According to the Centers for Disease Control and Prevention, patients with a particularly severe infection requiring prolonged hospitalization may have long-term health problems caused by this disease. The damage that occurs in the blood vessels results in a disease process called a "vasculitis," and bleeding or clotting in the brain or other vital organs may occur. Loss of fluid from damaged vessels can result in loss of circulation to the extremities, and damaged fingers, toes or even limbs may ultimately need to be amputated. Patients who suffer this kind of severe vasculitis in the first two weeks of illness may also be left with permanent longterm health problems such as profound neurological deficits, or damage to internal organs. Those who do not have this kind of vascular damage in the initial stages of the disease typically recover fully within several days to months. Epidemiology and Trends In 2014, no cases of Rocky Mountain spotted fever were reported in Indiana. Cases are reported by county of residence and may not always reflect the site of tick exposure. You can learn more about Rocky Mountain spotted fever by visiting the following Web site. Rubella is spread from person to person via airborne transmission or droplets shed from respiratory secretions of infected persons. Public Health Significance Symptoms of rubella include rash, low-grade fever, malaise, lymphadenopathy and upper respiratory symptoms. Symptoms of rubella typically appear 12-23 days after exposure, and as many as 50 percent of infections may be subclinical or inapparent. Fetal death, spontaneous abortion, premature delivery, deafness, eye defects, cardiac defects and neurologic abnormalities can occur. At least one dose of rubella-containing vaccine is recommended for all children 12 months of age or older. Prior to routine vaccination, the United States experienced the greatest number of rubella cases in 1969, with 57,686 cases reported (58 cases per 100,000 population). Indiana met this goal during the five-year reporting period 2010-2014, as one case was reported in Indiana in 2012, but it is unknown where the case acquired the disease. Aside from one case in 2012, no other cases of rubella have been reported in Indiana since 1999. There are thousands of types of Salmonella bacteria, most of which can infect humans. People become infected with Salmonella by ingesting feces from an infected animal or person (fecal-oral route). Historically, widespread salmonellosis outbreaks have been linked to the consumption of eggs, poultry, ground beef, tomatoes, leafy greens, melons and commercially processed foods. Contact with live animals, such as poultry or reptiles, or dried pet food/treats have been associated with widespread salmonellosis outbreaks. Persons who work in certain occupations (food handlers, daycare providers, and health care providers) have a greater risk of transmitting infection to others. Public Health Significance: Symptoms of salmonellosis may include diarrhea, stomach cramps, fever, nausea or vomiting. Infected people may carry Salmonella in their bodies for weeks or months without symptoms and unknowingly infect others. Rarely, Salmonella can enter the blood stream and infect organs such as the heart, lungs and bones. Children under age 5, the elderly and people with weakened immune systems are at the greatest risk for severe complications. Most people recover within 5-7 days without medical treatment, but antibiotics are available if indicated. In general, salmonellosis can be prevented by strictly adhering to the following guidelines: fi Practice good hygiene: o Thoroughly wash hands with soap and water after using the restroom; after assisting someone with diarrhea and/or vomiting; after swimming; before, during and after food preparation; and after exposure to raw meat products. Indiana met this goal in 2011, 2013, and 2014 during the five-year reporting period 2010-2014 (Figure 1).

The following counties had the highest incidence rates of salmonellosis in 2014: Spencer (48. You can learn more about salmonellosis by visiting the following Web sites. There are four species of Shigella bacteria: sonnei, flexneri, boydii and dysenteriae. Shigellosis can be very serious in infants, the elderly and people with weakened immune systems. People become infected with Shigella by having contact with stool from an infected person (fecal-oral route). Infection may be transmitted in several ways: fi Consuming food or beverages prepared by an infected person. Persons who work in certain occupations, such as food handlers, daycare providers and healthcare providers, have a greater risk of transmitting infection to others. Children are especially prone to shigellosis due to poor hand washing habits and the tendency to put their hands or objects in their mouths. Public Health Significance Symptoms of shigellosis include diarrhea, sudden stomach pain, cramps, fever and vomiting. Symptoms usually begin 24-72 hours (range of 12 hours to five days) after exposure and last about 4-7 days. In general, shigellosis can be prevented by strictly adhering to the following guidelines: fi Practice good hygiene: o Thoroughly wash hands with soap and water after using the restroom; after assisting someone with diarrhea and/or vomiting; after swimming; and before, during and after food preparation. Epidemiology and Trends In 2014, 1,366 cases of shigellosis were reported in Indiana, for a case rate of 20. The number of cases of shigellosis in Indiana was much higher than is typically seen due to a large outbreak in 2014. The onset of illness in the outbreak ranged from March 3, 2014, to February 27, 2015. Counties with outbreak cases included Marion, Hamilton, Hendricks, Hancock, Howard, Johnson, Shelby, Boone, Grant, Henry, Madison, Morgan, Rush and Vigo.

You can learn more about shigellosis by visiting the following Web sites. The virus localizes in the blood vessels of the dermis and oral and pharyngeal mucosa, resulting in the characteristic maculopapular rash, which evolves into vesicles, then pustules. The last case of smallpox worldwide was identified in 1977 and the last case of smallpox in the U. Public Health Significance Past use of smallpox in bioweapons programs and recent political instability in some areas of the world have led political and scientific leaders to consider the possibility that smallpox virus could be utilized as a Category A biological weapon. In 2003, a national effort was made to vaccinate a corps of medical responders to provide care for initial cases in the event of a smallpox virus release. Routine vaccination of the public was discontinued in 1972 after smallpox was declared eradicated in the United States. Because initial presentation of smallpox is similar to other rash illnesses, it may not be diagnosed until other differential diagnoses are ruled out by physicians. In light of the seriousness of the disease and the security threat it poses, it is important that physicians understand and recognize the symptoms of smallpox and diagnose accordingly, especially in individuals at greater risk as bioterrorism targets. Epidemiology and Trends In Indiana, no reported cases of smallpox have been reported more than 60 years. You can learn more about smallpox by visiting the following Web sites. More serious and life-threatening illnesses such as streptococcal bacteremia/sepsis, streptococcal toxic shock syndrome and necrotizing fasciitis can occur when the bacteria invade a site in the body where bacteria are not normally found, such as the blood or muscle tissue. Necrotizing fasciitis ("the flesh-eating disease") is a rapidly progressive infection that destroys muscle, fat and skin tissue. The bacteria are transmitted through direct contact with nose and throat secretions of persons who are infected or by touching infected hands. Spread may also occur by contact with infected wounds or sores on the skin, such as chickenpox lesions. Bacteria spread more easily in crowded settings, such as dormitories, barracks, child care centers or correctional facilities. All wounds should be kept clean and watched for signs of redness, swelling, drainage and pain at the site. A person with signs of an infected wound, especially if fever is present, should seek medical attention immediately. Healthcare providers may recommend that people who are exposed to someone with invasive disease or those who are identified as carriers in outbreak situations take antibiotics to prevent the spread of infection. Figure 1 shows reported cases by year for the five-year reporting period 2010-2014. As shown in Figure 3, age-specific incidence rates were greatest for adults over the age of 80 (13. Figure 3: Group A Streptococcus + Incidence Rates* by Age Group, Indiana, 2014 16. Incidence rates were highest among the following counties reporting five or more cases during the year: Grant (10. You can learn more about group A streptococcal disease by visiting the following website. More serious and life-threatening illness including meningitis, bacteremia, sepsis or joint infections can occur when the bacteria invade a site in the body that is sterile, such as the blood, cerebrospinal fluid or joint fluid. Cases most often occur in young infants and adults with chronic medical conditions. Live-birth data is used in the calculations of early-onset and late-onset disease. Healthy People 2020 Goal the Healthy People 2020 Goal for early-onset group B strep disease is 0. This finding should be interpreted with caution, as 2013 natality data was used in the calculation.

Gastric lavage, induced emesis, and scheduled including hemodialysis and alkalinization of urine. Drugs that are repeated doses of activated charcoal have not been shown to be 403 removed by hemodialysis include salicylates, methanol, ethylene Figure 10. Specific Drug Overdose Examples To follow will be a concise review of specific drug overdoses and their management. Please also refer to Table 1 for general categories of drugs, their overdose presentation, and specific management. Acetaminophen A common drug used in attempted suicides, acetaminophen toxicity occurs when N-acetyl-p-benzoquinoneimine depletes glutathione stores in the liver; this leads to hepatoxicity. Decreasing the suspected acetaminophen overdoses as well as other accumulation in the brain is accomplished by alkalinization of the presentations of acute liver failure. Laboratory findings may not be diagnostic (ie: normal SpO2, Calcium channel blockers and beta blockers are common PaO2, and Hgb saturation, however, SvO2 may be elevated). Management is with sodium nitrite (induces blocks, junctional rhythms, hypotension, and hyperglycemia. Glucagon is the Lastly, methemoglobinemia is acquired by exposure to oxidizers main treatment and blood pressure support may also be which create a ferric ion in Hgb.

A 31 year-old patient is brought to the emergency department after being found at home, unconscious, lying next to an empty b. Severely injured patients cannot tolerate prolonged interventions, so resuscitation of the trauma patient. It is mandatory to maintain cervical undergone damage control surgery and those admitted for nonspine stabilization during this process until an underlying injury operative management of solid organ injuries. Figure 1 illustrates a typical emergency management of the trauma patient centers on goal-directed airway algorithm for trauma patients. Treatment and diagnosis must occur simultaneously with management prioritized to the greatest threat to life or limb. Critical questions that should be continually entertained are: what can kill this patient and what are we missingfi Primary Survey the primary survey focuses on the rapid evaluation and correction of physiological functions crucial to survival. Assessment and intervention occur contemporaneously following 409 After a patent and protected airway is confirmed, breathing is the the fourth priority is a focused neurological exam. Disability is second priority demanding rapid assessment to ensure adequate assessed by determining the level of consciousness, pupillary oxygenation and ventilation. The respiratory rate and efiort are size and reactivity, and any focal sensory or motor deficits.

Life and limb threatening Finally, the patient is fully exposed and thoroughly examined, injuries that must be ruled-out at this stage include pericardial while preventing or reversing hypothermia. The clothes are tamponade, blunt cardiac injury, vascular disruption and removed and the patient is log-rolled with axial cervical hemorrhagic shock. Resuscitation is typically accomplished with stabilization to assess the integrity of the spine and to search for the rapid infusion of crystalloid fiuids and/or blood products. Additional interventions range from the insertion of invasive Secondary and Tertiary Surveys monitoring and resuscitation catheters to immediate fracture reduction to restore pulses to a bedside thoracotomy to prevent the secondary survey involves a head-to-toe examination while exsanguination. A more 410 thorough history is sought, serial labs obtained, diagnostic specificity (98%), negative predictive value (98%) and accuracy images reviewed and monitoring upgraded. For example, undetected hemorrhage is a common oversight Finally, laboratory analysis can aid in both diagnosis and during the initial evaluation of the trauma patient. A comprehensive panel of laboratory where blood can accumulate and remain unaccounted for include tests is initially drawn from all severely injured trauma patients. Here, immediate operative intervention is modalities such as ultrasound, computed tomography and mandated to find and stop the source of the bleeding. Many metropolitan trauma centers have protocolized imaging algorithms that provide a head-to-toe Coagulopathy in the severely injured patient significantly radiographic evaluation of all severely injured, polytrauma infiuences mortality rates. Four transducer positions can quickly assess for free provide reliable end-points of resuscitation and correction to fiuid in the pericardium, subdiaphragmatic space, hepatorenal. Elevated creatinine kinase and myoglobinuria signal prevalent in leading trauma centers and the data supporting their rhabdomyolysis and should trigger aggressive hydration guided use becomes more robust. An anion gap acidosis, hypocalcemia, of the coagulation status of severely injured patients with the and hyperkalemia all frequently occur and need to be treated. Kidney injury arises from tubular cast formation, hemoglobin cytotoxicity and vasoconstriction. Lactate is a marker of anaerobic metabolism hypotensive, received contrast agents, or have a history of and is suggestive of occult hypoperfusion. A serum creatinine level that adequate resuscitation and satisfactory end-organ perfusion. It is more common following intra-arterial decompensation must immediately commence. The suggested that using serial lactate levels to guide treatment of creatinine level typically peaks at approximately 96 hours and critically ill patients may reduce mortality. Damage Control Surgery and Resuscitation Creatine Kinase and Myoglobin: Damage control surgery has evolved as a temporizing measure to Rhabdomyolysis commonly occurs with crush injuries, burns, mitigate the lethal triad of hypothermia, acidosis and prolonged immobilization, extremity compartment syndromes and coagulopathy often responsible for the early mortality of severely 412 injured trauma patients. Blunt injury to the heart should be suspected in any trauma patient with a mechanism consistent with significant thoracic Pulmonary Contusion impact. An electrocardiogram Pulmonary contusion is the most common parenchymal lung should be obtained and the patient placed on continuous injury associated with blunt trauma. This injury is easily disruptions, assessing cardiac function and identifying pericardial overlooked because both clinical and radiographic findings tend tamponade. In fact, pulmonary contusions can occur in the can be easily visualized to rule-out a tear or dissection. At-risk patients must be closely monitored for Rib Fractures respiratory failure over the ensuing days. Rib fractures are the most common injury seen with thoracic Vascular Injuries trauma. Blunt injury to a vessel may not be immediately apparent Centers that have implemented protocols to identify and depending upon its severity and location.
