A) Hypersensitivity Reactions Definition Hypersensitivity reactions refer to bacteria quotes buy generic clavipen 1000mg on-line exaggerated response of immune system to virus in midwest order clavipen 625mg an antigen (foreign body) antibiotic 1g cheap clavipen 1000mg. The purpose of the immune response is to antibiotics libido buy 625mg clavipen otc protect against invasion by foreign organisms, but they often lead to tissue damage. Thus, an immune response that results in tissue injury is broadly referred to as a hypersensitivity reaction. Classification: · Hypersensitivity reactions can be divided into 4 types depending on the mechanism of immune recognition involved and on the inflammatory mediator system recited, which is Gell and Combs classification. Susceptibility to allergy is inherited and may result from excessive IgE-production. Pathophysiology the immune response is activated when antigen binds to IgE antibodies attached to the surface of mast cells Mast cells are found in connective tissue, skin, and mucus membranes. The reaction proceeds when the IgE molecule specific for a particular antigen become crosslinked on the surface of mast cell and triggers the release of intracellular granules. Histamine causes peripheral vasodilatation and an increased vascular permeability, resulting in local vascular congestion and edema. Delayed Hypersensitivity - It is due to the specific interaction of T-cells with antigen. The T-cells reacts with the antigen and release lymphokines that draws macrophages in to the area and elicit inflammatory reaction locally. Reddening and indurations of the site begins with in 12-72hours - Example Contact Dermatitis A common allergic skin reaction It is a T-cell response with a delayed reaction It occurs on contact with certain common household chemicals, cosmetics and plant toxins. The lymphocytes and macrophages infiltrate the area and react against the epidermal cells. Rejection is defined as the process by which the immune system of the host recognizes, develops sensitivity to, and attempts to eliminate the antigenic differences of the donor organ. Cytotoxic Tlymphocytes may either attack grafted tissues directly or secretes chemotactic cytokines that activate macrophages for tissue destruction. B) Immunodeficiency diseases Definition:The term immunodeficiency covers a group of disorder in which defects result in impaired resistance to microbial infections. Classifications 64 Pathophysiology Deficiencies of specific immune response are divided into primary and secondary types. Primary immunodeficiency diseases:Are those disorders which usually manifest in early childhood and there is a good evident that the disease is genetically determined. Primary immunodeficiency diseases which are almost always genetically determined are further divided into:· · · Deficiencies of antibody (B - cells). Combined T-cells and B-cells Deficiency (Severe combined immunodeficiency disease) · Complement factor deficiency. Contains different types of glycoprotein like gp-120 and gp-41 on the envelopes, which helps for binding of the virus into the host target cells. Fusion ·Binding of the virus to the co-receptors results in fusion of viral envelope with cell membrane of the target cells (Macrophages and T-lymphocytes) ·Fusion is followed by release of viral core into the host cell cytoplasm by uncoating its envelope. Then the viral genetic material synthesizes its own proteins for replication using the host machinery (genetic material). Assembly the newly synthesized viral proteins are assembled in to virions by protease enzyme. Budding 69 Pathophysiology the assembled virions buds it self by taking cell membrane as an envelope then released in to the circulation. Viral-Dissemination the released virus in to the circulation disseminate to all tissue of the body by lymphocytes. This results in fusion of the cell membranes and subsequent syncytium formation these syncytiums are highly unstable, and die quickly. Review Questions 76 Pathophysiology 1) Define different types of body defense mechanism 2) What are the common types of phagocytes based on their site? Differentiate acute and chronic obstructive pulmonary diseases Discuss pathophysiology of occlusive diseases of the blood vessels.

Centennial, Colorado: National Association of State Motorcycle Safety Administrators. Young Drivers Overview Motor vehicle crashes are the leading cause of death for teenagers in the United States. In comparison with adult drivers, young drivers are substantially over-involved in crashes. Between 1996 and 2005, there was a 42% decrease in the fatal crash rate for 16-year-old drivers (from 33 to 19 per 100,000 population). By comparison, fatal crashes rates declined by 15% among adult drivers ages 30-59. There was a similarly large decrease (41%) in police-reported crash involvements among 16-year-old drivers, as well as substantial decreases in nighttime fatal crashes and fatal crashes involving passengers (Ferguson, Teoh, & McCartt, 2007). The reasons for the dramatic reductions in fatal and police-reported crashes among 16-year-olds are not entirely known; however, it is 6-1 noteworthy that most States implemented new, multi-stage licensing systems during this time period. Presently, fatal crashes among 16-year-olds are at a historic low (Ferguson et al. Young drivers have high crash risks for two main reasons, as documented by extensive research (summarized in Hedlund, Shults, & Compton, 2003). The mechanics of driving require much of their attention, so safety considerations frequently are secondary. They do not have experience in recognizing potentially risky situations or in reacting appropriately and controlling their vehicles in these situations. In fact, research on adolescent development suggests that key areas of the brain involved in judgments and decision making are not fully developed until the mid-20s (Dahl, 2008; Keating, 2007; Steinberg, 2007). Inexperience and immaturity combine to make young drivers especially at-risk in four circumstances: · At night: Driving is more difficult and dangerous at night for everyone, but particularly for teenagers. Young drivers have less experience driving at night than during the day, and fatigue and alcohol may be more of a factor at night (Lin & Fearn, 2003; Williams, 2003). Driver education was developed to teach both driving skills and safe driving practices. Based on evaluations to date, school-based driver education for beginning drivers does a good job at teaching driving skills, but does not reduce crashes. Rather, some research has suggested that it lowers the age at which teenagers become licensed, and therefore increases exposure, so its overall effect is to increase crashes (Roberts et al. At least one driving guide program has successfully encouraged parents to impose more driving restrictions on their teens (SimonsMorton, 2007); however, no program has yet been shown to reduce young driver crashes or fatalities. The law enforcement system faces several problems when dealing with young drivers. Once stopped, there may be a tendency for officers in some situations not to make arrests or for prosecutors to dismiss charges because the offender is "just a kid.

This method classifies wounds according to antibiotic vancomycin side effects proven clavipen 625 mg the likelihood or rate of wound infection treatment for dogs fleas discount clavipen 375mg line. Clean: Non-traumatic virus on android phone safe 1000 mg clavipen, non-infected wound antimicrobial use and resistance in animals purchase clavipen 625 mg fast delivery, no break in sterility technique, the respiratory, gastrointestinal or genitourinary tracts not entered. Clean-contaminated: Minor break in technique, oropharynx entered, gastrointestinal or respiratory tracts entered without significant spillage, genitourinary or biliary tracts entered in absence of infected urine or bile. Follow up, re-inspect the wound and assess the outcome of your management after a day or two. However, the goal in all cases is to establish a good environment to assist wound healing and prevent infection. Proper wound care includes the following measures: · · · · · · Adequate hemostasis locally to stop bleeding. However, general guidelines that can be followed are: · · · · Clean wounds should be closed primarily Clean-contaminated wounds can be primarily closed if they can be converted, into clean wounds Untidy, contaminated wounds which cannot be converted to tidy wounds should not be closed primarily All missile wounds, animal and human bites should never be primarily closed unless strongly indicated Primary closure Primary closure is effective in wounds presenting within 6-8 hours and can accurately be debrided. It provides a reliable drainage and opportunity for repeated inspection and debridement as necessary. There is no specific management needed except local compress and analgesics if pain is severe. Management: It usually gets absorbed spontaneously and should be left Local compress to alleviate pain Aseptic evacuation or aspiration only if very large (expanding) or over a cosmetic area or leading to compression of vital structures. Management: Punctures these may be compound wounds which involve deeper structures. Cleanse using scrubbing brushes Use antiseptic or lean tap water and soap Analgesic 52 Management: Evaluate the depth of damage Remove pricking or other foreign bodies Excise damaged tissue Cover with antibiotics Tetanus prophylaxis Lacerations these are open wounds caused by an object moving across the skin, commonly by sharp and thin objects which slice with minimal energy, like a knife, or glass, but can also be due to high-energy impact. Management: Careful inspection Adequate cleansing Closure, if feasible, under appropriate anesthesia Proper wound debridement if needed Appropriate antibiotic prophylaxis Tetanus Prophylaxis Analgesics as needed Crush and avulsion wounds these are compound complicated wounds. They are usually associated with systemic involvement and have more extensive damage than may appear. Management: Correct associated life threatening conditions Proper wound debridement Early skin cover if possible or late graft, wound left open if contaminated Appropriate antibiotics Tetanus Prophylaxis Analgesics as needed Missile injuries these are type of wounds which are compound and complicated. They usually present with severe life threatening conditions and should be carefully managed. Human bites these are relatively rare but more heavily contaminated than those of most animalss due to polymicrobial nature including anaerobic organisms as a normal oral flora. Careful wound inspection Take culture from wound site Thorough scrubbing and liberal irrigation with saline or plain water Adequate debridement Leave wound open except early face and head wounds Do not suture severed tendons and nerves primarily Broad-spectrum antibiotics, later to be changed to specific antibiotics according to culture result Dog bites Peculiar to dog bites is that infected animals can transmit the rabies virus from the saliva which leads to rabies, a deadly disease. To avoid this complication the animal must be kept for observation for at least 10 days. Tetanus prophylaxis Antibiotics Snake Bites Poisonous snakes cause severe local and systemic effects due to highly active substances in their venom. Management should include: First aid measures: Local wound irrigation Apply pressure bandage proximally to avoid or reduce venom spread with caution on the blood supply Immobilize the limb to minimize venom absorption Transport patient immediately to nearby hospital Hospital Measures: Identify the species Conduct necessary laboratory investigations like hemoglobin, renal function. Local: Local complications may manifest as one or more of the following conditionsHematoma Seroma 55 Systemic: - Infection Dehiscence Granuloma formation Scar formation Contracture leading to loss of joint function etc Death may occur if un controlled sepsis or hemorrhage Systemic manifestations of hemorrhagic shock due to massive bleeding Bacteremia and sepsis from a source of locally infected wound 56 Review Questions 1. A) Duration of injury B) the circumstance of wounding C) the mechanism of injury D) Local appearance of the wound E) All of the above 2. A) Bullet wound of one hour duration B) Human bite of 30 minutes duration C) Glass laceration of five hours duration D) Crush injury of the leg following car accident E) None of the above 3. A proper wound care includes all measures except A) Removing all devitalized tissue B) Removing foreign bodies impregnated to the wound C) Wound inspection following primary management D) Inadequate hemostasis of a bleeding artery E) Decision to close a wound primarily 4. A) Forearm laceration from a knife B) Dog bite to the calf of one hour duration C) Blast wound to the thigh of two hours duration D) Stick wound to the scalp of four hours E) B and C are correct 5. In a contaminated wound left open to heal without closure, healing is effected by A) First intention B) Second intention C) Third intention D) Purely by epithelialization E) All of the above 7. A) Presence of foreign body B) Systemic illness C) Sex of the patient D) Poor patient nutritional state E) Presence of infection 58 Key to the Review Questions 1. It can be defined broadly as an infection related to or complicating a surgical therapy and requiring surgical management. Many infections occupy a non-vascularized space of tissue, thus are likely to respond to non-surgical treatments. These types of infection therefore definitely require surgery as a primary or definitive therapeutic approach.
