It is also important to remember that police involvement in the detention of individuals From: Clinical Forensic Medicine: A Physician’s Guide neurontin 300mg for sale medicine keppra, 2nd Edition Edited by: M generic neurontin 600mg on line treatment resistant schizophrenia. These acts are considerably harder to define and perhaps sometimes result from the police being placed in, or assuming, a role of caring (e. Police involvement with an individual can also include those who are being pursued by the police either on foot or by vehicle, those who have been stopped and are being questioned outside the environment of a police station, and those who have become unwell through natural causes while in contact with or in the custody of the police. The definitions of “death in custody” are therefore wide, and attempts at simple definitions are fraught with difficulty. Any definition will have to cover a multitude of variable factors, in various circumstances and with a variety of individuals. The crucial point is that the police owe a duty of care to each and every member of the public with whom they have contact, and it is essential that every police officer, whether acting or reacting to events, understands and is aware of the welfare of the individual or individuals with whom he or she is dealing. The number of deaths recorded in police custody in England and Wales from 1990 to 2002 (2) shows considerable variation year to year but with an encouraging decline from the peak in 1998 (Fig. In contrast, the data from Australia for much of the same period show little change (3) (Fig. These raw data must be treated with considerable care because any changes in the death rates may not be the result of changes in the policy and practice of care for prisoners but of other undetermined factors, such as a decline in arrest rates during the period. Legal Framework In the United Kingdom, all deaths occurring in prison (or youth custody) (4) must be referred to the coroner who holds jurisdiction for that area. How- ever, no such obligation exists concerning deaths in police custody, although the Home Office recommends (5) that all deaths falling into the widest defini- Deaths in Custody 329 Fig. This acceptance that all deaths occurring in custody should be fully investi- gated and considered by the legal system must represent the ideal situation; however, not every country will follow this, and some local variations can and do occur, particularly in the United States. Protocol No standard or agreed protocol has been devised for the postmortem examination of these deaths, and, as a result, variation in the reported details of these examinations is expected. These differences in the procedures and the number and type of the specialist tests performed result in considerable varia- tion in the pathological detail available as a basis for establishing the cause of death and, hence, available for presentation at any subsequent inquest. The absence of a defined protocol hinders the analysis of the results of these examinations and makes even the simplest comparisons unreliable. There is an urgent need for a properly established academic study of all of these deaths, such as that performed in Australia under the auspices of the Australian Insti- tute of Criminology (6), to be instituted in the United Kingdom and the United States. Terminology In addition to the lack of reproducibility of the postmortem examina- tions, the terminology used by the pathologists to define the cause of death, particularly in the form required for the registration of the death, may often be idiosyncratic, and similar disease processes may be denoted by different pathologists using many different phrases. For example, damage to the heart muscle caused by narrowing of the coronary arteries by atheroma may be termed simply ischemic heart disease or it may be called myocardial ischemia resulting from coronary atheroma or even by the “lay” term, heart attack (7). This variation in terminology may lead to confusion, particularly among lay people attempting to understand the cause and the manner of death. A consid- erable amount of research (1,7) has been produced based on such lay assess- ments of the pathological features of a death, and this has, at times, resulted in increased confusion rather than clarification of the issues involved. If the issues regarding the definition of “in custody,” the variation in the postmortem examinations and the production of postmortem reports, and the use and analysis of subsequent specialist tests all raise problems within a single country, then the consideration of these deaths internationally produces almost insuperable conflicts of medical terminology and judicial systems. Clearly, a death, whether sudden or delayed, may Deaths in Custody 331 Table 1 Expected Types of Deaths in Different Phases of Custody Accidental Self- Deliberately Natural trauma Alcohol Drug inflicted inflicted Prearrest ++ +++ ++ ++ Arrest ++ +++ ++ ++ ± +++ Detention + + +++ +++ ++ ++ Interview + + ++ ++ +++ ++ Charge + + – – +++ ± occur for many reasons even in the absence of police, but because it is the involvement of police that is the sine qua non of “in custody,” deaths in the first phase must be considered to be the presence of police officers at the scene. Subsequently, an arrest may be made with or without the use of restraint tech- niques and the prisoner will then be transported to a police station. This trans- port will most commonly involve a period within a police vehicle, which may be a car, a van with seating, or some other vehicle. Many factors may determine the type of transport used and the position of the individual in that vehicle. Detention in the police station will be followed by an interview period inter- spersed with periods of time incarcerated, usually alone, within a cell. After the interview, the individual may be released directly, charged and then released, or he or she may be detained to appear before a court. It is at this point that custody moves from the police to other authorities, usually to the prison service. When considering the types of death that can occur during each of these phases, six main groups can be identified based on the reported causes of death. It is clear that different factors may lead directly to or play a major part in the death of an individual while in custody and that different factors will play their part at different phases in the period of custody (see Table 1).
Accordingly generic 100 mg neurontin with amex symptoms ptsd, once rearrangement of the Ig genes has taken place best neurontin 600mg medications covered by medi cal, the corresponding protein will be expressed as a surface receptor. The body faces a large number of different antigens in its lifetime, necessitating that a correspondingly large number of different receptor specificities, and therefore different B cells, must continuously be produced. When a given antigen enters an organism, it binds to the B cell which exhibits the correct receptor specificity for that antigen. One way to describe this process is to say that the antigen selects the corresponding B-cell type to which it most effi- ciently binds. However, as long as the responding B cells do not proliferate, the specificity of the response is restricted to a very small number of cells. For an effective response, clonal proliferation of the responsive B cells must be induced. After several cell divisions B cells differentiate into plasma cells which release the specific receptors into the surroundings in the form of soluble antibodies. B-cell stimulation proceeds with, or without, T cell help depending on the structure and amount of bound antigen. Antigens can be divided into two categories; those which stimulate B cells to secrete antibodies without any T-cell help, and those which require additional T-cell signals for this purpose. These include paracrystalline, identical epitopes arranged at approximately 5–10 nm intervals in a repetitive two-dimensional pattern (e. Either type of antigen can induce B cell activation in the absence of T cell help. These antigens are less stringently arranged, and are usually flexible or mobile on cell surfaces. These are monomeric or oligomeric (usually soluble) antigens that do not cause Ig cross-linking, and are unable to induce B-cell proliferation on their own. In this case an additional signal, provided by contact with T cells, is required for B-cell activation (see also B-cell tolerance, p. Receptors on the surface of B cells and soluble serum antibodies usually re- cognize epitopes present on the surface of native antigens. For protein anti- gens, the segments of polypeptide chains involved are usually spaced far apart when the protein is in a denatured, unfolded, state. A conformational or structural epitope is not formed unless the antigen is present in its native configuration. So-called sequential or linear epitopes—formed by contigu- ous segments of a polypeptide chain and hidden inside the antigen—are lar- gely inaccessible to B cell receptors or antibodies, as long as the antigen mol- ecule or infectious agent retains its native configuration. The specific role of linear epitopes is addressed below in the context of T cell-mediated immunity. B cells are also frequently found to be capable of specific recognition of sugar molecules on the surface of infectious agents, whilst T cells appear to be in- capable of recognizing such sugar molecules. As mentioned above, contact between one, or a few, B-cell receptors and the correlating antigenic epitope does not in itself suffice for the induction of B-cell proliferation. Instead proliferation requires either a high degree of B cell receptor cross-linking by antigen, or additional T cell- mediated signals.

Usage subject to terms and conditions of license Immune Responses and Effector Mechanisms 69 result in errors, or even the activation of oncogenes. The results of this process may therefore include the generation of B-cell lymphomas and leukemia’s. Uncontrolled proliferation of differentiated B cells (plasma cells) results in the generation of monoclonal plasma cell tumors known as multiple mye- 2 lomas or plasmocytomas. Occasionally, myelomas produce excessive amounts of the light chains of the monoclonal immunoglobulin, and these proteins can then be detected in the urine as Bence-Jones proteins. Such proteins represented some of the first immunoglobulin components acces- sible for chemical analysis and they revealed important early details regard- ing immunoglobulin structure. It is possible to isolate a single cell from such a polyclonal immune response in an experimental setting. Fusing this cell with an “immortal” proliferating myeloma cell results in generation of a hybridoma, which then produces chemically uniform immunoglobulins of the original specificity, and inwhatever amounts are required. This method was developed by Koeler and Milstein in 1975, and is used to produce mono- clonal antibodies (Fig. Many monoclonal antibodies are still produced in mouse and rat cells, making them xenogeneic for hu- mans.
