The presumed purpose of its use would be therefore not as a Weapon of Mass Destruction but rather as a Weapon of Mass Disruption medications varicose veins order carbidopa 300mg otc. For Barton medicine 513 purchase 125mg carbidopa overnight delivery, what distinguishes disasters from other types of collective stress medications heart failure carbidopa 110mg mastercard, such as war treatment for hemorrhoids 300 mg carbidopa, is that the sources of disasters are external rather than internal. What is missing in this view is any understanding of the ways that political and economic forces create conditions that result in an earthquake having disastrous impacts for some people and communities. Disaster: "A sudden calamitous emergency event bringing great damage loss or destruction. This is partly because of growing awareness that through negligence or inappropriate response, the workings of social systems have made a disaster out of a 10/27/08 277 situation which otherwise might not have been so serious. There has also been a growth in understanding that it is hazards that are natural, but that for a hazard to become a disaster it has to affect vulnerable people" (Cannon 1994, 16). A catastrophe is known by its works; that is to say, by the occurrence of disaster. So long as the ship rides out the storm, so long as the city resists the earth-shocks, so long as the levees hold, there is no disaster. It is the collapse of the cultural protections that constitutes the disaster proper" (Carr 1932, 211). Disasters are simply the collapse of cultural protections; thus, they are principally man-made. Deductively, mankind is responsible for the consequences of his actions as well as of his omissions" (Dombrowsky 1998, 24-25). Disaster: "A disaster is an emergency considered severe enough by local government to warrant the response and dedication of resources beyond the normal scope of a single jurisdiction or branch of local government. Disasters originate from many sources, just as hazards do (natural systems, social systems, technology failures). Disaster: "An event in which a community undergoes severe danger and incurs, or is threatened to incur, such losses to persons and/or property that the resources available within the community are exceeded. In disasters, resources from beyond the local jurisdiction, that is State or Federal level, are required to meet the disaster demands. Thus, any effort at disaster reduction involves planning and action by various social units. In a community disaster, the pattern of damage may extend to several different places in the community rather than being focalized as it is within a community accident. Also, a number of community structures, perhaps including those that might house the traditional emergency organizations, might be damaged or destroyed. The increased involvement of other nonemergency organizations then creates the need for coordination of activity and for new patterns of communication among parts of the community that previously had no reason to communicate" (Dynes 1998, 119). As used in this Guide, a "large-scale disaster" is one that exceeds the response capability of the local jurisdiction and requires State, and potentially Federal, involvement. Dombrowsky 1998, 20 citing Seeck 1980, 1) 17 Disaster: An "extraordinary situation in which the everyday lives of people are suddenly interrupted and thus protection, nutrition, clothing, housing, medical and social aid or other vital necessities are requested. Dombrowsky 1998, 20, citing KatastrophenVorschrift 1988, 2) 18 Disaster: the result of (1) the impact of external forces, (2) social vulnerability, or (3) uncertainty. Disaster: "The result of a vast ecological breakdown in the relations between man and his environment, a serious and sudden event (or slow, as in drought) on such a scale that the stricken community needs extraordinary efforts to cope with it, often with outside help or international aid. They arise from the behavior of complex systems, are perceived and take place in a specific socio-economic, historical, cultural and chronological context. Disaster: "Disasters are non-routine events in societies or their larger subdivisions. Among the key defining properties of such events are (1) length of forewarning, (2) magnitude of impact, (3) scope of impact, and (4) duration of impact" (Kreps 1998, 34). Horlick-Jones (1995) argued in favor of defining disasters as originating in the fundamental social conditions of late-modern society and as involving disruptions of cultural expectations and the release of existential dread.

For example treatment concussion 300 mg carbidopa with amex, the description of the rehabilitation process associated with Audrey and other observations point instead to the following facts doctor of medicine safe 300mg carbidopa. While it may have been true that certain interpersonal conflicts which had loomed large to people before the storm were temporarily reduced medications memory loss generic carbidopa 125mg overnight delivery, it is equally if not more true that new conflicts arose which were more severe in consequence for the social system than those that had existed before. Furthermore, old community and political loyalties seemed to form the axis around which new and serious conflicts developed. In the early stages (first pulse of an air burst), when the temperature of the fireball is extremely high, the ultraviolet radiation predominates; in the second pulse, the temperatures are lower and most of the thermal radiation lies in the visible and infrared regions of the spectrum. For high-altitude bursts (above 100,000 feet), the thermal radiation is emitted as a single pulse, which is of short duration below about 270,000 feet but increases at greater burst heights. Extended Definition: includes capabilities, intentions, and attack methods of adversaries used to exploit and circumstances or occurrences with the intent to cause harm. D-12, Glossary) Threat: "Potential cause of an unwanted incident, which may result in harm to individuals, a system or organization, the environment or the community. It is assumed for planning purposes that such an attack, if it comes, will consist principally of nuclear weapons delivered by air, and detonated above ground during normal working hours. It is further assumed that high explosive and incendeiary bombs will also be used, that sabotage will be employed, and that biological and chemical weapons will be used. The threat assessment process is centered upon on analysis of the facts and evidence of behavior in a given situation. The appraisal of risk in a threat assessment focuses on actions, communications, and specific circumstances that might suggest that an individual intends to mount an attack and is engaged in planning or preparing for that event. In a situation that becomes the focus of a threat assessment inquiry or investigation, appropriate authorities gather information, evaluate facts, and make a determination as to whether a given student poses a threat of violence to a target. If an inquiry indicates that there is a risk of violence in a specific situation, authorities conducting the threat assessment collaborate with others to develop and implement a plan to manage or reduce the threat posed by the student in that situation. Targeted violence stems from an interaction among the individual, the situation, the setting, and the target. An investigative, skeptical, inquisitive mindset is critical to successful threat assessment. The central question in a threat assessment inquiry or investigation is whether a student poses a threat, not whether the student has made a threat. Thunderstorms are associated with convective clouds (Cumulonimbus) and are, more often, accompanied by precipitation in the form of rain showers or hail, or occasionally snow, snow pellets, or ice pellets. When local resources are overwhelmed by an event or if specific required technical capabilities are not available, local leaders may implement existing mutual-aid agreements to request additional support from neighboring communities and seek supplemental assistance through county and state emergency management systems. It is not necessary that each level become overwhelmed, or fail, prior to surging resources from another level. Most incidents begin and end locally and are wholly managed at the community level. Many incidents require additional resources or support from across the community, and some require additional support from neighboring communities or the State. National response protocols recognize this and are structured to provide additional, tiered levels of support when there is a need for additional resources or capabilities to support and sustain the response and initial recovery. During largescale events, all levels will take proactive actions to respond, anticipating resources that may be required. Time: the amount of radiation exposure increases and decreases with the time people spend near the source of radiation. In general, we think of the exposure time as how long a person is near radioactive material. When this happens, the biological half-life of the radionuclide controls the time of exposure. Biological half-life is the amount of time it takes the body to eliminate one half of the radionuclide initially present. Distance: the farther away people are from a radiation source, the less their exposure. It depends on the energy of the radiation and the size (or activity) of the source.

The best examples are found in patients with the aortic-arch syndrome (Takayasu pulseless disease medications gout safe 300 mg carbidopa, page 732) symptoms 9 dpo quality carbidopa 110 mg, in which the brachiocephalic medications quizzes for nurses generic carbidopa 110mg mastercard, common carotid in treatment 2 best 110mg carbidopa, and vertebral arteries have become narrowed. Physical activity may then critically reduce blood flow to the upper part of the brainstem, causing abrupt loss of consciousness. Stenosis or occlusion of vertebral arteries and the "subclavian steal syndrome" are other examples (page 678). Fainting is said also to occur occasionally in patients with congenital anomalies of the upper cervical spine (Klippel-Feil syndrome) or cervical spondylosis, in which the vertebral circulation is compromised. Head turning may then cause vertigo, nausea and vomiting, visual scotomas, and finally unconsciousness. Syncope does not occur with ischemic attacks that are confined to the territory of the internal carotid artery. Cerebral Hemorrhage and Syncope the onset of a subarachnoid hemorrhage may be signaled by a syncopal episode, often with transient apnea. Because the bleeding is arterial, there is a momentary cessation of cerebral circulation as intracranial pressure and blood pressure approach one another. The light-headedness of anxiety and hyperventilation are frequently described as a feeling of faintness, but a loss of consciousness does not follow (see Linzer et al). The diagnosis is made on the basis of the associated symptoms, the absence of laboratory and tilt-table abnormalities, and the finding that part of the attack can be reproduced by having the patient hyperventilate. The symptoms produced in this way mimic the persistent or episodic dizziness that accompanies anxiety and panic states (Chap. When anxiety attacks are combined with a Valsalva effect or prolonged standing, fainting may occur. The relationship of anxiety-panic to the previously described postural orthostatic tachycardia syndrome is uncertain. Hypoglycemia In nondiabetics, hypoglycemia may be an obscure cause of episodic weakness and very rarely of syncope. Acute Blood Loss Acute hemorrhage, usually within the gastrointestinal tract, is a cause of weakness, faintness, or even unconsciousness when the patient stands suddenly. The cause (gastric or duodenal ulcer is the most common) may remain obscure until the passage of black stools. Transient Cerebral Ischemic Attacks the many symptoms comprised by these attacks in the carotid system are fully described in Chap. In the case of attacks in the vertebrobasilar territory, an impairment of consciousness is a rare manifestation, but almost always in the context of additional signs of upper brainstem dysfunction. Drop Attacks this term is generally applied to falling spells that occur without warning and without loss of consciousness or postictal symptoms. The patient, usually elderly and more often female, suddenly falls down while walking or standing, rarely while stooping. There is no dizziness or impairment of consciousness, and the fall is usually forward, with scuffing of the knees and sometimes the nose. The patient, unless obese, is able to right herself and to rise immediately and go her way, quite embarrassed. One potential mechanism is a lapse of tone in leg muscles during the silent phase of an unnoticed myoclonic jerk. Drop attacks also occur in hydrocephalics, and these patients, though conscious, may not be able to arise for several hours. Drop attacks as defined above are usually without an identifiable mechanism, requiring no treatment if cardiologic studies are normal. In only about one-quarter of such cases, according to Meissner and coworkers, can an association be made with cardiovascular or cerebrovascular disease, to which treatment should be directed. Seizures and Syncope In the final analysis, the loss of consciousness in the different types of syncope must be caused by impaired function of the neural elements in those parts of the brain subserving consciousness, i. In this respect syncope and primary generalized (so-called centrencephalic) epilepsy have a common ground; yet there is, of course, a fundamental difference. The difference relates to the essential pathophysiology- the rapid spread of an electrical discharge in epilepsy and a more gradual failure of cerebral circulation in syncope. There are also a number of important clinical distinctions between epileptic and syncopal attacks. The epileptic attack may oc- cur day or night, regardless of the position of the patient; syncope rarely appears when the patient is recumbent, the only common exception being the Stokes-Adams attack.

Plantar flexor responses medicine sans frontiers generic 125 mg carbidopa overnight delivery, succeeding extensor responses medicine knowledge cheap carbidopa 125mg otc, signify ether a return to normalcy or treatment 02 binh purchase 125 mg carbidopa with mastercard, in the context of deepening coma schedule 9 medications purchase 110 mg carbidopa amex, a transition to brain death. This phenomenon has been attributed to isolation of the brainstem respiratory centers from the cerebrum, rendering them more sensitive than usual to carbon dioxide (hyperventilation drive). It is postulated that as a result of overbreathing, the blood carbon dioxide drops below the concentration required to stimulate the centers, and breathing gradually stops. Carbon dioxide then reaccumulates until it exceeds the respiratory threshold, and the cycle then repeats itself. It may occur during sleep in elderly individuals and can be a manifestation of cardiopulmonary disorders in awake patients. Only when it gives way to more irregular respiratory patterns that implicate structural damage of the brainstem is the patient in imminent danger, as discussed below. A number of other aberrant breathing rhythms occur with brainstem lesions (these are reviewed in Chap. The more conspicuous respiratory arrhythmias are associated with brainstem lesions below the level of the reticular activating system and are therefore found in the late stages of brainstem compression or with large brainstem lesions such as infarction, primary hemorrhage, or infiltrating tumor. This disorder is characterized by an increase in the rate and depth of respiration to the extent that respiratory alkalosis results. It must be distinguished from hyperventilation caused by medical illnesses, particularly pneumonia and acidosis. Mild degrees of hyperventilation are common after a number of acute neurologic events, notably head injury. However, North and Jennett, in a study of respiratory abnormalities in neurosurgical patients, found no consistent correlation between tachypnea and the site of the lesion. With lesions of the dorsome- dial part of the medulla, the rhythm of breathing is chaotic, being irregularly interrupted and each breath varying in rate and depth (Biot breathing; also called "ataxia of breathing"- not an appropriate term. Probably all of these erratic patterns of breathing are interrelated in some manner; Webber and Speck have shown that apnea, Biot breathing, and gasping could be produced in the same animal with lesions in the dorsolateral pontine tegmentum by altering the depth of anesthesia. Rapidly evolving lesions of the posterior fossa may cause sudden respiratory arrest without any of the aforementioned abnormalities of breathing; presumably this results from fulminant pontomedullary compression by the cerebellar tonsils. Papilledema develops within 12 to 24 h in cases of brain trauma and hemorrhage, but if it is pronounced, it usually signifies brain tumor or abscess- i. Increased intracranial pressure produces coma by impeding global cerebral blood flow; but this occurs only at extremely high levels of pressure. High pressure within one compartment produces shifts of central structures and a series of "false localizing" signs due to lateral displacements and herniations, as noted in the above discussion of herniation. The syndrome of acute hydrocephalus, most often from subarachnoid hemorrhage or from rapid obstruction of the ventricular system by a tumor in the posterior fossa, induces a state of abulia (page 359) followed by stupor and then coma with bilateral Babinski signs the pupils are small and tone in the legs is increased. Laboratory Procedures Unless the diagnosis is established at once by history and physical examination, it is necessary to carry out a number of laboratory procedures. If poisoning is suspected, aspiration and analysis of the gastric contents is sometimes helpful, but greater reliance should be placed on chromatographic analysis of the blood and urine ("toxic screen"). A specimen of urine is obtained by catheter for determination of specific gravity and for glucose, acetone, and protein content. Proteinuria may also be found for 2 or 3 days after a subarachnoid hemorrhage or with high fever. Urine of high specific gravity, glycosuria, and acetonuria occur almost invariably in diabetic coma; but transient glycosuria and hyperglycemia may result from a massive cerebral lesion. Blood counts should be obtained, and in malarial districts a blood smear should be examined for parasites. Neutrophilic leukocytosis occurs in bacterial infections and also with brain hemorrhage and infarction, although the elevation of leukocytes in the latter conditions rarely exceeds 12,000/mm3. This is the only way to reveal nonconvulsive status epilepticus as the cause of a stupor. Diseases that cause no focal or lateralizing neurologic signs, usually with normal brainstem functions. Metabolic disturbances: anoxia, diabetic acidosis, uremia, hepatic failure, nonketotic hyperosmolar hyperglycemia, hypo- and hypernatremia, hypoglycemia, addisonian crisis, profound nutritional deficiency, carbon monoxide, thyroid states including Hashimoto encephalopathy (Chaps.
