The captured data can then be used to reconstruct thin sections with detail discount prinivil 2.5mg otc, which can help to diagnose disease within the arteries (pulmonary arteries purchase prinivil 5mg line, aorta) or the veins (systemic or pulmonary veins). The injected dye helps delineate blood vessels better by opacifying the vessels selectively and thus serving as effective contrast from non-vascular structures which are not opacified. Diseases such as clot formation within the pulmonary arteries (pulmonary embolism) and abnormalities of the aorta including tears (dissections) and dilatations (aneurysms) which can rupture, can be diagnosed effectively by this technique. Benefts Painless, fast and easy to perform, making it ideal for use in medical emergencies. This carries a slight increased risk of cancer, which needs to be weighed against the benefits of obtaining a diagnosis. Pregnant women have an increased risk to themselves and to the fetus from radiation exposure. Risks from the injected contrast material include an allergic-like reaction to dye and damage to kidney functions. Allergic reactions, like minor rashes occur with some frequency, while serious (anaphylactoid) reactions are exceedingly rare. When the risk-benefit ratio supports the use of contrast, patients can be pre-medicated with steroids and other medications before the study. Risk of contrast induced kidney damage is more common in patients who have borderline or pre-existing impaired renal function. Certain medications and disease states predispose to development of contrast induced kidney disease and need to be stopped or the dosages modified after consulting a physician. Ample hydration and pre-medication with kidney protective agents has shown some value in preventing severe renal damage from injected radio contrast. This is particularly useful in imaging of children and very sick, medically-unstable patients. The imaging study involves injection of a radioactive glucose into the blood stream. The radioactive tracer accumulates in the organ system or body tissues which are most metabolically active. In these tissues, the radiotracer releases small amounts of energy in the form of gamma rays. These rays are then detected by a special camera, which converts the signal into computer-processed images of that part of the human body. The study may determine that a suspicious nodule is metabolically inactive and may be benign. A metabolically active lesion may be either due to infection or cancer and a decision on whether to biopsy the nodule can then be made. Lactating women must be instructed to stop breast feeding for 24 hours after the procedure. It is a non-invasive imaging modality which uses a powerful magnetic field and radio waves to generate signals from different body parts, which are then processed by computer to generate detailed images of the human body. This is particularly useful in imaging the beating heart and the great blood vessels in the chest. The study is contraindicated in patients with cardiac pacemakers and defibrillators. It is sometimes difficult to ascertain whether they are benign (such as a result of infection or scar) or malignant (cancerous). A sample (not the entire nodule) is removed and examined directly under a microscope to look for signs of cancer or other diseases. Preparatory Instructions Patients are instructed to fast for at least six to eight hours before the procedure. Any history of allergy and prior complication to anesthesia needs to be recognized. Although all patients are given local anesthetic injections around the skin puncture site, some may need additional dose of intravenous sedation to alleviate anxiety and fear. Hence, it is important that all patients are accompanied by family or friend(s) who can accompany the patient or drive them home after the procedure. Nature of the Procedure Needles A biopsy needle is a hollow needle, which varies in length (can be several inches in length) and in diameter, but is usually no wider than a paper clip. Two different types of needles may be used depending on the type of sample being obtained. One is a fine needle (thinner than a blood drawing needle) and the other is a core needle (slightly thicker and contains an inner needle attached to a spring device). The fluoroscopy equipment consists of a radiographic table, x-ray tube and a monitor with screen.

Herd Health Plan Needed to maintain the overall health of the herd Key to success of the plan is the prevention of problems before they start Vital Signs of Beef Cattle Temp. Symptoms of Blackleg First sign is one or more animals suddenly die Before death symptoms are: Lameness Swollen muscles Severe depression High fever (in early stages) Animal may be unable to stand Preventing Blackleg Vaccination Calves are vaccinated when young (typically in the spring at branding or shortly after calving) and again at weaning (fall) Dead animals should be burned or buried Treating Blackleg Massive doses of antibiotics Treatment is only effective if diagnosed early Prevention is more effective and less costly. Calf Enteritis (Scours) Disease complex (group of diseases) Most common in fall, winter and spring Afflicts young calves-calves over 2 months of age are seldom affected Symptoms of Scours Vary Acute form Calf is in a state of shock Nose, ears and legs are cold Diarrhea Sudden death Chronic form Symptoms for several days Weight loss Death after several days if not treated Preventing Scours Sanitation is the most important factor! How Pinkeye Spreads Insects Direct Contact with infected animals Dust Tail switching Controlling Pinkeye Control flies and insects to prevent pinkeye Vaccinations are available to control Moraxella bovis, the bacteria that is considered to be the main cause of pinkeye Treating Pinkeye Animals should be isolated in a dark place Antibiotics and sulfa drugs are applied to the eye Medicine should be applied 2 X s/day Why??? Treatment of Shipping Fever Antibiotics Sulfa drugs Treatment must begin as soon as symptoms are noticed Treatment after an animal has developed pneumonia is of little value. Trichomoniasis A venereal disease caused by a protozoan, Trichomona fetus The organism infects the genital tract of the bull and is transmitted to the cow during breeding Clean bulls can also be infected by breeding dirty cows The disease can also be transmitted through infected semen, even when artificial insemination is used. Symptoms Abortion in early gestation Low fertility Irregular heat periods Uterine infection Cows may have discharge from their genital tract Bulls may not show any symptoms of the disease but still be capable of transmitting it to the cow during breeding The organism is identified by microscopic examination of material from an aborted fetus, the prepuital cavity of the bull or vaginal discharge from the cow Prevention No treatment or vaccination for trich Infected bulls should be slaughtered Use only clean bulls on clean cows Test bulls to ensure they are free of the disease Use semen from clean bulls Campylobacteriosis (Vibriosis) Reproductive disease Both intestinal and venereal Leading cause of infertility and abortion in the cattle industry Campylobacteriosis Intestinal form has little harmful effect Venereal form is more serious If the organism infects the uterus there will be some abortion in the herd Number of cows infected is usually small Cows do not become sterile and bulls are not affected. Ringworm A contagious skin disease that can be spread to other animals and humans Symptoms Round, scaly patches of skin that lack hair May appear on any part of the body The affected area clears up but moves to another part of the body Sanitation helps control ringworm Isolate infected animals Treat ringworm with iodine tincture or quaternary ammonium compounds Ringworm Nutritional Health Problems (X) Bloat Occurs when rapid fermentation in the rumen causes to much gas to be produced The rumen swells and the animal can not get rid of the gas Bloat The major cause of bloat is eating to much green legume too fast Ways to prevent bloat Prevent animals from eating to much legume Feed grain, dry roughage or silage before turning animals onto legume pastures Free access to water should be provided at all times Bloat Treatments Stomach tubes Walking the animal on rough ground and forcing it to burp Forcing the animal to drink mineral oil or poloxalene (trade name Bloat Guard) Inserting a trocar and cannula into the rumen through the side This should only be considered after other methods have failed. Enterotoxaemia (Overeating Disease) Usually affects cattle on high-concentrate rations Symptoms Lameness Bloody diarrhea Bloat The animal may die in 1-24 hours Vaccinating calves 2 weeks before putting them on high concentrate rations helps prevent overeating disease Treatments Removing concentrates from the diet Feeding roughage Vaccinating Animals may gradually be put back on the high concentrate ration after vaccination.

Treats to our lung health are everywhere, and they start at an early age, when we are most vulnerable. Fortunately, many of these threats are avoidable and their consequences treatable. Te purpose of this document is to inform, raise awareness and assist those who advocate for protecting and improving respiratory health. It tells of the magnitude of respiratory diseases and the threats to lung health across the globe. It is not intended to be a comprehensive textbook, but instead is a guide emphasising the diseases of greatest and immediate concern. It outlines practical approaches to combat threats to respiratory health, and proven strategies to signifcantly improve the care we provide for individuals aficted with respiratory diseases worldwide. Te document calls for improvements in healthcare policies, systems and care delivery, as well as providing direction for future research. In brief, it outlines ways to make a positive diference in the respiratory health of the world. We would like to thank everyone involved in the development of this work, especially Don Enarson and his colleagues who comprised the Writing Committee. We would also like to express our sincere appreciation to Dean Schraufnagel for his careful and expert review. We intend to update this document regularly, and seek feedback and suggestions for ways to improve it. On behalf of those sufering from respiratory disease and those who are at risk of respiratory disease in the future, we ask for your help in making a diference and a positive impact on the respiratory health of the world. Te journals of these societies publish the vast majority of respiratory scientifc breakthroughs in the world. Teir memberships comprise over 70 000 professionals, who devote their working lives to some aspect of respiratory health or disease. Te members of these societies cover the globe and touch many, or most, persons with serious respiratory disease. At least 2 billion people are exposed to the toxic efects of biomass fuel consumption, 1 billion are exposed to outdoor air pollution and 1 billion are exposed to tobacco smoke. Nine million children under 5 years of age die annually and lung diseases are the most common causes of these deaths. Asthma is the most common chronic disease, afecting about 14% of children globally and rising . Te most common lethal cancer in the world is lung cancer, which kills more than 1. Te lungs are the largest internal organ in the body and the only internal organ that is exposed constantly to the external environment. Everyone who breathes is vulnerable to the infectious and toxic agents in the air. While respiratory disease causes death in all regions of the globe and in all social classes, certain people are more vulnerable to environmental exposures than others. At the same time, increasing healthcare costs have threatened many nations fnancial health, and the efort needed to care for the ill and dying afects national productivity. It has become abundantly clear that the economic development of countries is tightly linked to the health of its citizens. Poor health, both individual and public, along with lack of education and lack of an enabling political structure, are major impediments to a country s development and are the roots of poverty. Poor health impoverishes nations and poverty causes poor health, in part related to inadequate access to quality healthcare. Healthcare costs for respiratory diseases are an increasing burden on the economies of all countries. If one considers the lost productivity of family members and others caring for these individuals, the cost to society is far greater.
