...Staphylococcal toxic shock syndrome Staphylococcus aureus is commonly found on the skin and mucous membranes of healthy adults and children and by age 25, 90% of the general population will have antibodies against the organism.1 Staphylococcal aureus is also known to be the causative agent to several infections that range from folliculitis, to abscess and endocarditis. In 1972, a syndrome of fever, myalgias, sore throat, edema, scarlatiniform rash, and desquamation associated with Staphylococcus aureus infection was first described. In 1978, Todd and colleagues reported seven cases in children who presented with similar symptoms as described in 1972 of fever, headache, conjunctival hyperemia, rash. These cases also presented with acute renal failure, hepatic abnormalities, DIC, and shock: “One patient died, one had gangrene of the toes, and all have had fine desquamation of affected skin and peeling of palms and soles.”3 Staphylococcus aureus was isolated from mucosal (nasopharyngeal, vaginal, tracheal) but not from blood and the term toxic shock syndrome (TSS) was coined.2,3 The peak incidence of Staphylococcus aureus related illness was seen in 1980 when 890 cases were reported, 91% of which were related to the use of super...

...excessive rainfall or flooding. Etiology Virtually all wild and domestic mammals can harbour the bacteria that cause leptospirosis in their kidneys and genital tracts and act as source of infection to humans and other animals. • Rodents were the first recognized carriers of leptospirosis and are considered the primary source of infection to human beings. • Cattle, buffaloes, horses, sheep, goat, pigs and dogs are also considered common reservoirs of the bacteria that causes leptospirosis. Pathophysiology • Leptospirosis can be transmitted to humans through cuts and abrasions of the skin, or through the mucous membranes of the eyes, nose and mouth with water contaminated with the urine of infected animals. As animals are constantly in our environment, there is a particular danger of getting leptospirosis when flooding occurs, such as following a typhoon or very heavy seasonal rains, because of exposure to contaminated water when wading in floodwaters. • Leptospirosis can occasionally also be transmitted through the drinking of water or ingestion of food contaminated with urine of infected animals, often rats. • Human-to-human transmission occurs only very rarely. Risk Factors Outbreaks of leptospirosis have been reported following natural disasters such as flooding. The risk of infection depends on exposure. Some humans have a high risk of exposure because of their occupation, the environment they live in or their lifestyle. The main occupational groups at risk include: ...

...far more mortality rates than war itself. Numerous cases of disease outbreaks in the past have been a major concern to health authorities, although such concerns have been partially addressed in the recent past. Examples of disease outbreaks in the past include: the infamous Bubonic Plague of the 14th century in Europe that led to the death of approximately a quarter of the continent’s population (approximately 25 million people); the influenza pandemic of 1918 to 1919 that led to the death of 21 million people; and the death of 95% of Pre-Columbian Native American people by measles, plague, small pox, influenza, and typhoid (Magner, 2009). Although there has been some response to such epidemics in the recent past, naturally occurring infections still remain the Achilles’ heel of today’s health systems. 2. Terrorism Versus Bioterrorism Despite the dark past in healthcare systems, current issues of the use of biological agents as means of mass destruction is alarming. Most of the countries across the globe are now faced with the daunting task of terrorism control, since this is one area where biological agents find a lot of use. According to Forst, terrorism may be defined as a “premeditated and unlawful use of violence [on] non-combatant populations having symbolic significance….” (Forst, 2009). Forst mentions that the premeditated and unlawful use of violence usually has an aim of inducing or influencing changes in existing political landscapes; this is normally done through...

...went to a Philadelphia convention of the American Legion suffered from an outbreak of this disease, a type of pneumonia (lung infection). Although this type of bacteria was around before1976, more illness from Legionnaires' disease is being detected now. This is because we are now looking for this disease whenever a patient has pneumonia. Where do Legionella bacteria come from? The Legionella bacteria are found naturally in the environment, usually in water. The bacteria grow best in warm water, like the kind found in hot tubs, cooling towers, hot water tanks, large plumbing systems, or parts of the air-conditioning systems of large buildings. They do not seem to grow in car or window air-conditioners. How do people get Legionnaires' disease? People get Legionnaires' disease when they breathe in a mist or vapor (small droplets of water in the air) that has been contaminated with the bacteria. One example might be from breathing in the steam from a whirlpool spa that has not been properly cleaned and disinfected. The bacteria are NOT spread from one person to another person. Outbreaks are when two or more people become ill in the same place at about the same time, such as patients in hospitals. Hospital buildings have complex water systems, and many people in hospitals already have illnesses that increase their risk for Legionella infection. Other outbreaks have been linked to aerosol sources in the community, or with cruise ships and hotels, with the most likely...

She has gained weight because of the lack of exercise she has performing. Wright complains she is too tired to work out and gets tired throughout the day performing normal activities. She also insists she cannot work out because she always gets hot flashes from her menopause and is simply too hot to work out. Wright also explained she lives alone and cannot always go to see a physician because she cannot get someone to drive her there. She is no longer taking the three medications, hydroxychloroquine, methotrexate, and prednisone, prescribed by Dr. Ruppert. She explains she had experienced intolerable side effects, including reflux, alopecia, and severe photosensitivity. Dr. Ruppert ordered a comprehensive laboratory evaluation and identified the following: IgG4 food-specific antibodies, essential fatty acid and amino acid imbalances, nutrient and essential element deficiencies, and dysbiosis, in addition to elevated antinuclear antibodies (ANA) and high sensitivity c-reactive protein (hs-CRP).

...Clinical Case Study Assignment 2014 Jennifer Ahonen Cambrian College a00050951 BSN 2144: Nursing Practice Frances Carvalho & Jillian Smythe March 21, 2014 Clinical Case Study Assignment 2014 The purpose of this paper is to utilize the data collected in the Gordon’s Functional Health Patterns Assessment Tool (Appendix A). After data collection, it will be analyzed and a priority nursing diagnosis will be used to make a care plan (Appendix B). Patient X is an 82 year old male, who presented to the emergency department from his home at Extendicare York with a fever of 38.9 degrees Celsius, a blood pressure of 75/40 mm Hg, blood glucose level of 3.7, diaphoretic and a three day history of diarrhea, nausea and generalized weakness. The admitting diagnosis for this 82 year old male was Pneumonia. Pneumonia is an acute inflammation of the lower respiratory tract due to an infectious agent that impairs gas exchange due to alveolar edema and congestion (Thiem, Heppner, & Pientka, 2011). There are many factors that predispose individuals to pneumonia; however, in the case of this patient the predisposing factors are age and the presence of chronic diseases. The patient’s complete history and demographics can be found in Appendix A. The classic clinical manifestations of pneumonia consist of a temperature above 38 degrees Celsius, diaphoresis, cough, and shortness of breath, chest pain, tachycardia, purulent sputum, fatigue, nausea, vomiting, and diarrhea (Thiem, Heppner...
