Case Study 3.2- Terri is a 42-year-old female. She is married and has four children. Terri lives a very active lifestyle and enjoys gardening and sewing. She recently saw her health care provider because she was having pain in her hands. The pain was limiting the activities that Terri could participate in. Terri also noted that the joints in her fingers were erythematous and that she felt very tired most of the time. Terri was diagnosed with rheumatoid arthritis. She was referred to a rheumatologist for her treatment. 1. Rheumatoid arthritis is an example of chronic inflammation. Compare and contrast the process of acute inflammation and the process of chronic inflammation. 2. Discuss the cellular response and adaptation to the chronic inflammation that is occurring within Terri's joints. 3. Draw a concept map linking the cellular response and adaptation to the long-term alterations Terri will experience with rheumatoid arthritis. Do these alterations have any impact on other tissue / systems within the body? 4. Describe the structural and functional changes that occur as a result of rheumatoid arthritis. 5. How will Terri's body attempt to compensate for these changes? 6. Consider this: How would having rheumatoid arthritis change your current lifestyle?

1. Acute inflammation will resolve within a fairly short period of time. Chronic inflammation occurs over a period of time and may cause alteration of the cells/tissues because of the prolonged stressors placed on those cells. These alterations can result in functional changes within the tissue. 2. Local changes occur within the joints in a symmetrical fashion. Clinical manifestations include erythema, pain, swelling, warmth, and decreased mobility. Over time, changes occur within the joints, causing malalignment or deviation of the joints. 3. Because of the chronic inflammation in the joints, destruction of the tissue will occur. Because of the tissue destruction, Terri will experience an alteration of the normal function in her joints and will not have the flexion and extension capabilities. Systemic response to the chronic inflammation includes fever, fatigue, anemia, anorexia, weight loss, and weakness. Also, consider the fact that chronic pain can also lead to situational depression. 4. Joint destruction over time will cause joint malalignment and deviation. This would make it difficult for Terri to perform even simple activities such as combing her hair, brushing her teeth, or driving her car. 5. In response to the systemic alterations that occur with rheumatoid arthritis such as anemia, compensation will occur because of the low hemoglobin. The body will respond as follows: increased respiration rate and increased heart rate. The body is attempting to maintain homeostasis by increasing the supply of oxygen (increased respiration) and moving it around the body faster (increased heart rate). 6. Pain, decreased ability to care for oneself, and decreased ability to participate fully in activities that you may enjoy.

Case Study 3.1- Brian is an active 13-year-old who lives on a farm. During the spring planting season, he was filling the tractor with fuel. As he was talking the nozzle out of the tank, a spark ignited the fuel. Brian dropped the nozzle and ran to the house. His older sister pushed him to the ground and smothered the flames on his shirt. Brian was taken to the emergency department for treatment of his burns. He had deep partial-thickness burns covering both of his arms. 1. Consider the inflammatory response in relation to Brian's burns. What kinds of local and systemic responses are occurring both at the site of injury and within Brian's body? What is triggering these responses? 2. Would you expect Brian to experience pain with this type of burn? Why or why not? 3. What clinical manifestations would you expect to see with Brian's injury? Why are you seeing these particular manifestations (what processes are occurring within the body that are causing these manifestations)? Draw a map that links the manifestations to the causes. 4. Consider the healing process that takes place with this type of injury. How is new tissue formed? 5. Discuss the different types of treatment options available for Brian. 6. Discuss the potential complications of this type of a burn in relation to the following: a. a widespread inflammatory response b. stress hypermetabolism c. impaired defense mechanisms

1. Vascular response: Occurs immediately after tissue injury. This response involves the release of chemical mediators that control vascular permeability, leading to increased blood flow to the area. The vascular response includes activation of the complement system (source of chemical mediators). Cellular response: Cells required for tissue healing and repair respond to the injury. The steps involved include chemotaxis, cellular adherence, and cellular migration. -The catalyst or trigger for the acute inflammatory response is the tissue injury. 2. Yes. This type of burn will damage the epidermal skin layers. As long as the nerve cells are intact, Brian will feel the sensation of pain. 3. Brian would experience pain, redness, edema, and loss of function of the affected are. These clinical manifestations are attributable to the vascular and cellular responses occurring within his body. Also, depending on the size of the burns, there might be large fluid shifts within the body owing to the increase in the vascular permeability. 4. The wounds will heal by secondary intention. Increased blood supply to the area assists with the formation of granulation tissue within the wound bed. If the burn is superficial, the new tissue will gradually fill in the area. If necrosis of the tissue occurs in the upper epidermal layers, scarring is avoided. However, if tissue necrosis occurs in both epidermal and upper dermal layers, collagen will fill in the wound bed and lead to scarring. 5. Dressing changes with wound debridement and analgesics to manage the pain. Skin grafting would be an option as well, depending on the depth of the burn. 6. Complications include: a. The release of large amounts of chemical mediators can cause fluid shifts because of the vascular permeability. The fluid will shift from the vascular space into the interstitial space. b. To heal wounds, the body requires a large amount of energy and the metabolism will increase drastically. If the body's increased metabolic needs are not met, the following could occur: tissue hypoxia, tissue wasting, and infection. c. The skin is considered as the first line of defense. When the integrity of the skin is impaired, microbes can easily enter the body.
