Environment Occur in both saltwater and freshwater environments, particularly where there are high nutrient levels (in particular high levels of nitrogen and phosphorus) but can also occur frequently in low nutrient environments. Livestock may drink contaminated water or lick themselves after bodily exposure and become ill. Affecting water quality by causing oxygen depletion from respiration and bacterial degradation, and blocking of sunlight. This may appear in conjunction with occurrence of a marine reddish/orange tide or freshwater bloom (which initially appear green and may later turn blue sometimes forming a scum/foam in the water). Signs such as irritation of the skin, vomiting, paralysis, lethargy and loss of muscle co-ordination may be observed in birds. Not all toxic algal blooms are visibly noticeable and so a sample of organisms from the bloom may be useful or necessary for diagnosis. Recommended action if Contact and seek assistance from animal and human health professionals suspected immediately if there is any illness in birds, fish, marine mammals and/or people. Diagnosis Confirmative diagnosis is difficult and relies on circumstantial evidence and supportive clinical and pathologic findings. There are also currently no established toxic thresholds for wildlife species and even when these exist it may be difficult to assess their significance. Collect samples during the die-off event as soon as possible after carcases are found. Contact a diagnostic laboratory for advice on appropriate sample collection and transport. Plants such as reeds and willow, and constructed treatment wetland systems can remove sediments and pollutants especially in places which release high volumes of nutrients, such as animal and human sewage outlets. Monitoring and surveillance Careful monitoring and early detection of potentially toxic algal blooms could allow time to initiate actions to prevent or reduce harmful effects e. Monitor for changes in nutrient load of water discharges, particularly sewage discharges (including septic tanks and cesspits) and agriculture. Patrol to observe and map discoloured water or dead fish for early detection of potentially toxic algal blooms. Humans Do not fish in an algal bloom/discoloured water and never eat fish which are dead when caught. When swimming, look for warnings of algal blooms and avoid swimming if you cannot see your feet when the water level is at your knees. Ingestion of toxin may not cause mortality but have other less obvious physiological effects such as affecting immune, neurological and reproductive capability. Effect on livestock Mostly not harmful unless ingested through eating contaminated seafood/fish, drinking contaminated water or licking their coats following exposure to the skin. Effect on humans Mostly not harmful unless ingested through eating contaminated seafood/fish or drinking contaminated water. Some organisms irritate the skin and others release toxic compounds into the water and, if aerosolised by wave action, these compounds may cause problems when inhaled. Economic importance May have significant economic impacts on freshwater and marine aquaculture industries, fisheries and coastal tourism.

Lead is a highly toxic poison which can cause morbidity and mortality in humans, livestock and wildlife. Waterfowl, birds of prey and scavenging birds are at greater risk of exposure to lead than other bird species and mammals due to feeding habits that involve ingesting lead gunshot as grit or consuming prey animals that have been shot with lead ammunition. Lead poisoning in waterbirds is a very serious and large-scale environmental problem. Birds can die from lead poisoning throughout the year but mortality is more likely after waterfowl hunting seasons. Lead exposure may also cause a variety of health effects in humans, particularly for children, foetuses and pregnant women. Species affected Many species of birds, particularly waterbirds, birds of prey, scavenging birds, and mammals. Any species using an area where shooting with lead ammunition occurs or has occurred previously is at some risk of exposure and, potentially, poisoning. Lead-based paint, mine wastes, lead contaminated industrial effluents and other objects provide additional sources of contamination. How are animals exposed Waterfowl usually become poisoned after ingesting spent lead shot, mistaking to lead? Predators or scavengers may become poisoned after consuming animals that have been shot with lead ammunition. Lead from ammunition and fishing weights may slowly dissolve and enter groundwater, making it potentially harmful for plants, animals and perhaps humans if it enters water bodies or is taken up in plants. Lead poisoning in livestock often occurs after swallowing point sources of lead such as lead from inside vehicle/machine batteries or lead paint, but also through consuming contaminated water and food supplies. Cattle are at most risk due to their inquisitive natures and they often ‘taste-test’ objects. How are humans exposed Exposure to lead may occur through ingestion of contaminated food, such as to lead? Signs include weakness, lethargy, reluctance to fly or inability to sustainweakness, lethargy, reluctance to fly or inability to sustain flight, weight lossweakness, lethargy, reluctance to fly or inability to sustain causing emaciation (the breast-bone becomes prominent), greencausing emaciation (the breast bone becomes prominent), green-stained faeces and vent and fluid discharge from the bill. Those suffering from acute poisoning do not attempt to escape but will often seek isolation and protective coverattempt to escape but will often seek isolation and protective coverattempt to escape but will often seek isolation and protective cover making them difficult to find. In some species, the head and neck position may appear ‘crooked’ or bent during flight.

In recent years cheap ponstel 500 mg fast delivery muscle relaxant rocuronium, the world has observed major growth in the number and in the applications of medical imaging and radiotherapy technologies discount ponstel 250 mg without prescription spasms leg. This growth has had an impact on reducing disease mortality and increasing prevention in high income countries cheap ponstel 500mg with amex muscle relaxant pharmacology. Low income countries have difficulties in obtaining the benefits of such technological developments ponstel 250 mg discount muscle relaxer ketorolac. Multiple factors, such as infrastructure, health technology assessment and management, human resources, quality of care and safety, economic constraints and cultural aspects, contribute to the challenge. In particular, the lack of an appropriate regulatory infrastructure, well maintained equipment, trained staff and physical infrastructures, threatens the safety of patients and health workers. A more widespread use of medical imaging and radiotherapy technologies and improvement in treatment approaches will lead to a reduction in mortality and help to combat many diseases and conditions of public health concern, as well as to improved quality of life for people in developing countries. The services of radiation medicine encompass a wide spectrum of clinical applications. Modalities such as ultrasound and X ray examinations alone can solve around 80% of diagnostic problems in developing countries. Radiotherapy is used today for the treatment of many kinds of tumours, and is frequently administered in combination with surgery, chemotherapy or both. Demand for radiation medicine services has increased worldwide due to the global increase of diseases, new clinical applications, the increase in world population, an ageing population, lifestyle changes and worldwide health care programmes and reforms. The lack of appropriate infrastructure and technologies, well maintained equipment, trained staff, and governmental regulations, among other factors, threatens the safety of patients and health workers in low income countries. Even where the technology is available, both the quality and safety of the procedures may be questionable or even dangerous for the patient and health workers. Most of the mortality causes are conditions for which timely ultrasound imaging could increase survival rates . Acute lower respiratory infection, mostly pneumonia, is the leading cause of childhood mortality, accounting for about 4 million deaths per year in low income countries. Appropriate case management, focusing on early detection and treatment of the disease, has been challenging to implement, especially in low income countries that often face poor access to basic health care. Radiography would appear to be the best available method for diagnosing pneumonia if relevant health professionals knew how to interpret the images, and these met the necessary quality standards . Cardiac ultrasound has diagnostic applications that are particularly suited to the developing world because of its non-invasive nature. Internationally, it is believed that radiotherapy will continue to be key for the treatment of cancer in the coming decades for its curative function, which is particularly important for tumours of the head and neck, cervix–uterus, breast and prostate, and for its palliative function and effectiveness. Early detection methods for breast cancer, such as clinical exploration, ultrasound or mammography, improve the outcome of treatment. In addition, ultrasound is an essential component of the diagnosis and staging of breast cancer. Injury is the ninth most common cause of premature death worldwide and the third most common cause of years lived with disability. Most traffic related deaths take place in low and middle income countries among young men 15–44 years old. Road traffic deaths are likely to increase by more than 80% in developing countries by 2030 . Low income countries are also particularly vulnerable to intentional or non-intentional injuries, including natural disasters and war. Much of the mortality due to injuries and trauma could be avoided by timely stabilization and medical care, and timely use of emergency equipment, including basic diagnostic tests. Easy to use ultrasound devices for diagnosis of internal, especially intra-abdominal, bleeding would also be a useful development. Emergency care, including imaging techniques to diagnose bone trauma in health care facilities, is necessary for immediately addressing urgent health issues and to prevent long term disability. Standard radiology remains the major diagnostic tool for trauma and some types of injury. However, health systems in many developing countries are highly segmented and the provision of health services is very fragmented. Experience to date demonstrates that excessive fragmentation leads to difficulties in access to services, delivery of services of poor technical quality, irrational and inefficient use of available resources, unnecessary increases in production costs and low user satisfaction with services received . The specialized training needed to diagnose such diseases is a challenge for low and middle income countries. On the other hand, the lack of comprehensive cancer control programmes, including access to treatment services with radiotherapy, represents the major obstacle for reducing cancer mortality in developing countries. Technology and infrastructure Radiation medicine technology is associated with high costs from the acquisition to the functional phase, including maintenance needs and environmental conditions. The costs of these services, considering both the initial investment and operating costs, make careful planning and management of their development necessary, but the latter are not always adequate. Frequently, the costs of procuring and maintaining equipment are much higher than in industrialized countries. All these aspects become more critical with the incorporation of more complex and costly technologies. Almost two thirds of all low income countries do not have a national health technology policy in the national health programmes to guide the planning, assessment, acquisition and management of medical equipment. As a result, inappropriate medical devices that do not meet the priority needs of the population, are not suited to the existing infrastructure and are too costly to maintain are incorporated, draining funds needed for essential health services . Much of the most complex equipment imported from industrialized regions does not work when it reaches low income countries. Maintenance of diagnostic equipment plays a very significant role in the longevity and effectiveness of diagnostic machines, as well as in safety and quality. Better technology policy in countries will lead to an increase in the quality, effectiveness and coverage of health care with regard to medical devices. In some countries, the low demand for medical technology often derives from deep rooted culture and social norms. At the beginning of the symptoms, people tend to solve their problems with traditional medical services or even magic–religious approaches. Many prefer traditional over modern therapies, and it is very common to use a of combination of both. Often, when appropriate results are not produced, the patient then seeks modern medicine. Although the introduction of new technologies and techniques is necessary in some countries, awareness of the traditions and beliefs may be crucial to the success of any project. Some beliefs and culture can affect radiation medicine’s acceptability and accessibility. Human resources Most low income countries face challenges in radiation medicine services because of the lack of skilled human resources. As a consequence, general practitioners often have to interpret the radiological images; nurses or technical personnel, without adequate education and training, carry out the diagnostic examinations or the treatment delivery; and inappropriately trained physicists or engineers assume quality aspects, safety and maintenance responsibilities . On the other hand, there is a lack of mechanisms for the necessary certification or recognition of these professionals .
