This hemoglobinuria is common and nor- care, because perivascular injection causes severe mal for some nervous birds. In chickens, the clearance is markedly influ- that induced by chlamydia or Pacheco’s disease virus, enced by age and gender. Because many other severe clinical diseases cause this color to be present, it is not pathognomonic. Urinalysis Specific Gravity Urinalysis is indicated if renal disease is suspected. Normal: The specific gravity varies with the state of Polyuria is a common clinical presentation in com- hydration and with the individual bird.

Water deprivation should be used to of fluids (fruits, vegetables); by renal disease, neo- evaluate the kidney’s ability to concentrate low lev- plasia, diabetes, sepsis, toxins, adrenal disorders or els, often due to psychogenic polydipsia. In all of these cases, it is an increased loss of solute will create a low specific relatively easy to separate the urine from the feces gravity. This situation can be caused by intravenous via aspirating the liquid deposited on a water-resis- fluid therapy, hyperthyroidism, liver disease, pitui- tant surface. Transient polyuria can be induced by tary neoplasia, progesterone or glucocorticoid ther- administering water by crop tube. Any disease that causes polyuria and polydipsia result in urine production within 30 minutes after 73 can cause a low specific gravity. In pigeons, urine for analysis has concentrate or dilute the glomerular filtrate will lead been collected directly from the cloaca using a can- 26 to an increased specific gravity and severe renal nula. Normal com- stances that are on the border of this molecular panion birds produce a small quantity of urine, and weight cutoff are hemoglobin and albumin. Most if it can easily be collected it is generally abnormal other physiologic proteins have higher molecular (stress or disease). Most substances that are filtered by the companion bird species, but in other birds, such as kidneys are critical to normal bodily functions and ratites and Anseriformes, it is normally opaque, are completely reabsorbed (eg, amino acids, glucose, cloudy or slightly flocculent. The excretion or retention of other sub- stances are regulated according to the body’s needs. In diabetes mellitus, birds may have blood commercial test strips designed for use with human glucose concentrations above 800 mg/dl. It should be noted that the sensitivity of these tests has been adjusted to detect what would be Ketones regarded as abnormal levels of certain substances in Ketones should be absent from the urine of birds. These sensitivities are not necessarily significant shift in energy production from carbohy- applicable to birds and the fact that a “higher” read- drates to fats results in the increased oxidation of ing is obtained on an area of the test strip does not fatty acids and the production of intermediate meta- necessarily imply an abnormality. For example, alka- bolites that accumulate faster than they can be oxi- line urine can produce falsely elevated protein levels.

There are five major concerns about the use of these agents by law enforce- ment: 1 buy 500mg soma mastercard. The potential for any ancillary exposure to health care providers 350 mg soma for sale, and to bystand- ers (1–4). Concern about the long-term effects from repeated exposure and from occupa- tional exposure (5). Some of these issues become more complicated because chemical con- trol agents are increasingly popular with civilians as readily available, often legal, self-defense weapons. There have been several incidents in the United States and in other coun- tries that question the appropriateness of use of chemical crowd-control agents (5,6). When used appropriately, crowd-control agents have a good safety mar- gin and generally do no permanent harm. Despite all of the controversy surrounding chemical control agents, they offer a less hazardous method of restraint than other potentially lethal alternatives, such as firearms. These agents are available in varying concentrations, with several vehicles, in aerosols or foams and in particulate form with dispersal devices. Essentially a means of less lethal chemical warfare, chemical crowd- control products are used as defensive agents to temporarily incapacitate indi- viduals or disperse groups without requiring more forceful means. These agents share common effects that include lacrimation, ocular irritation and pain, dermal irritation, blepharospasm, conjunctivitis, transient impairment of vision, and mild to moderate respiratory distress (11–13). Some corneal defects after exposure have been noted, but whether this is a direct tissue effect of the agent, the vehicle, or dispersant or a result of rubbing the ocular surface is unknown 182 Blaho-Owens (14). Other more severe effects, such as pulmonary edema, have been documented when con- centrations are several hundred-fold above what produces intolerable symp- toms or with trauma associated with the explosive device used to deliver the chemical agent (6,15). All of these clinical effects produced by chemical crowd-control agents render the recipient temporarily unable to continue violent action or resist arrest. Because they all share a high safety ratio, are effective at low concen- trations, and can be used without direct forceful contact by the law enforce- ment officer, they are ideal agents for control of either the individual offender or riot control. Because of their relative safety, these agents are generally excluded from international treaty provisions that address chemical weap- ons. The United States, England, Ireland, France, China, Korea, Israel, and Russia are just some examples of countries that use these compounds as riot control agents. The legal availability to law enforcement and the general pub- lic differs between countries; however, most can be easily obtained through international markets or ordered through the Internet. For large crowds, “bombs” have been devel- oped that can be dropped from aerial positions producing wide dispersal of the compound. They are also formulated in grenades or canisters, which can be propelled by either throwing or with a projectile device. The most common method of dispersal is by individual spray cans that deliver a stream, spray, or foam containing the agent. These individual dispersal units were designed to render immediate incapacitation to an offender without the use of more forceful methods, thereby providing an extra means of control in the ladder of force used by law enforcement. Canisters containing a lower concentration of the active ingredient have been marketed to civilians for personal protection. There is no formal training for civilians on securing the devices, laws governing their use, deployment, or decontamination after exposure. This lack of training signifi- cantly increases the risk for exposure and adverse events to the users, the intended target, and bystanders. The physi- ological effects of these mediators’ results in vasodilation, increased vascular permeability, pain, and altered neurotrophic chemotaxis. The oleoresin extract of capsicum contains more than 100 volatile compounds that act similarly to capsicum (16). Most patients complained of ocular irritation and irri- tation and pain at the exposure site. The most significant adverse effects were corneal abra- sions, which were treated with topical anesthetics and topical antibiotics. No patient required treatment for wheezing, and two of the five had a history of reactive airway disease. No patient in this study had significant morbidity or mortality, Crowd-Control Agents 185 B C Fig. The cause of in-custody deaths can be difficult to determine because many times these deaths have other confounding factors besides restraint and chemi- cal control agents. Risk factors for sudden death, such as mental illness, drug abuse, and seizure disorders, may not be readily visible, and autopsy reports can often be inconclusive or incomplete. All of the prisoners who died exhibited characteristics consistent with excited delirium from substance abuse. Most were obese, had hyperthermia, were violent, and had measurable cocaine on postmortem analysis. The lesson learned from these cases is that all violent prisoners, regardless of whether a chemical restraint has been used, should be closely monitored and evaluated by appropriate health care professionals. A small population of acutely intoxicated individuals is at risk of sudden death, independent of their treatment.

Sample Citation and Introduction to Citing Individual Volumes With a Separate Title and Separate Authors/Editors Te general format for a reference to a volume with a separate title and separate authors/ editors: Examples of Citations to Individual Volumes With a Separate Title and Separate Authors/ Editors If each volume of a book in a multivolume set has its own author(s) or its own editor(s) distinct from the authors/editors of the set of volumes, the individual volume may be cited. Begin the reference with the authors or editors and title of the individual volume; cite the overall set of volumes as a series. Multivolume sets are bound alike with an essentially identical appearance and have one publisher. Te volumes in them are considered primarily as a part of the set and ofen, but not always, have the same date of publication or are published over a short span of years. Tis is in contrast to large open series such as Methods in Enzymology and Annals of the New York Academy of Sciences which have published hundreds of volumes over decades. Each volume in a multivolume set may have two title pages, one for the set and one for the individual volume. Use these title pages or their verso (back) for authoritative information to use in a citation.
