This places maximum tension on the tendon of insertion of the superficial pectoralis muscle. The insertion of the supracoracoideus muscle on the dorsomedial aspect of the coracoid must be avoided.

These birds are indigenous to South America, rang- ing from southern Mexico to northern Argentina. These birds have been maintained in captivity since the Spanish Conquistadors first landed in the Americas, but ac- tive breeding programs have occurred only during the past 30 years. These large, active birds require plenty of space for exercise and produce a voluminous, moist excrement, which may account for the low numbers of these birds that are main- tained as pets.

Ana- lytic methods such as electrophoresis without blot systems (Ab-dependent with blots), chromatography and nucleic acid probes are the most sensitive meth- ods of demonstrating virus. The recent advances in genetic engineering will certainly have profound ef- fects on virus detection in the future. The initial precipitating antibody changes induced by the virus, such as histologically titer was 0. The presence of a precipitation line at 1/80 (arrow) indicates that the bird seroconverted following vaccination and discernible inclusion bodies. Depending on the test objec- tive, either polyclonal or monoclonal antibodies can be used. Monoclonal antibodies are normally used for iden- tifying specific antigen structures and to differentiate between serotypes, subtypes, variants and mutants.

A relevant anamnestic report is valuable induced by prior exposure to an agent and those to help guide the laboratory diagnostic efforts. A rise or fall in Ab concentrations or a switch from IgM to IgG are indicative of an active infection. Egg yolk (containing IgG) can be used in place of serum for some diagnostic tests.

Hooding discount irbesartan 300mg without a prescription, prolonged standing purchase 300mg irbesartan otc, and the use of high-pitched sound have all been used, as have attempts to disorientate prisoners by offering food at erratic times, frequent waking up after short intervals of sleep, and burning a light in the cell 24 hours a day. Physical abuse includes beating of the soles of the feet, so-called falanga, which, although extremely painful and debilitating, does not usually cause any significant bruising. Repeated dipping of the victim’s head under water, known as submarining, may prove fatal if prolonged, as can the induction of partial asphyxia by enveloping the head in a plastic bag. Electric torture is well documented and carries the risk of local electric shocks and fatal electrocution. Telefono, as it is known in Latin America, con- sists of repeated slapping of the sides of the head by the open palms, resulting in tympanic membrane rupture. Doctors who have access to prisoners in custody have a heavy responsi- bility to ensure that they are properly treated during detention and interroga- tion. In all cases of suspected or alleged ill-treatment of prisoners, it is essential that the doctor carry out a methodical and detailed “head-to-toe” examina- tion. All injuries and marks must be accurately recorded and photographed, and the appropriate authorities must be informed immediately. Increasingly, forensic physicians are involved in assessments of refugees and asylum seek- ers to establish whether accounts of torture (both physical and psychologi- cal) are true. This role is likely to expand in the future, and the principles of independent assessment, documentation, and interpretation are, as with other 150 Payne-James et al. Introduction The term bite mark has been described as “a mark caused by the teeth alone, or teeth in combination with other mouth parts” (10). Recog- nition, recording, analysis, and interpretation of these injuries are the most intriguing challenges in forensic dentistry. Biting can establish that there has been contact between two people—the teeth being used for offense or defense. When individual tooth characteristics and traits are present in the dentition of the biter and are recorded in the biting injury, the forensic significance of the bite mark is greatly increased. Early involvement of the forensically trained dentist, with experience in biting injuries, is essential to ensure that all dental evidence from both the victim and any potential suspect(s) is appropriately collected, preserved, and evaluated. There may be insufficient evidence to enable comparisons to be made with the biting edges of the teeth of any par- ticular person, but, if the injury can be identified as a human bite mark, it may still be significant to the investigation. It is important that the forensic dentist discusses with investigators the evidential value of the bite mark to enable resources to be wisely used. Clearly, conclusions and opinions expressed by the forensic dentist often lead him or her into the role of the expert witness subject to rigorous examination in court. The forensic physician will mostly be involved with biting injuries to human skin and any secondary consequences, including infection and disease transmission, but should be aware that bites in foodstuffs and other materials may be present at a crime scene and be easily overlooked. It is essential that a human bite can be distinguished from an animal bite, thus exonerating (or incriminating) the dog or cat next door. The following sections will consider issues surrounding bites to human skin caused by another human. Early rec- ognition of a patterned injury (suspected of being caused by biting) by medi- cal personnel, social services, and other investigating agencies is extremely important; the injury may be the only physical evidence and must not be lost. Ideally, the forensic dentist should be contacted sooner rather than later when a possible biting injury is discovered to ensure that all evidence is collected appropriately. All too often the dentist is brought in at a later date, when there has been incorrect recording of the bite mark and the injury is partly healed and distorted or fully healed and no longer visible. Reliance may then have to be placed on ultraviolet photography to demonstrate the “lost” injury (11). Injury Assessment 151 Bites can be found on the victim or the assailant (living, deceased, child, or adult). It is well known that biting is often a feature in nonaccidental injury to children (see Chapter 5). If a bite mark is found on an anatomical site that is accessible to the victim, it becomes necessary to exclude him or her from the investigation. If the answer to the first question is “don’t know,” “possibly,” or “yes,” then request the assistance of the forensic dentist. Ensure that swabs are taken from the injured site (with controls) and photographs should be taken. Make sure that you know which forensic dentists are available in your area; this will prevent delays and frustration. You will need to know whether your local forensic dentist has experience and training in bite mark-analysis or whether he or she focuses mainly on identifications. The forensic dentist will examine the suspected biting injury and con- sider the following: • Whether the injury is oval or round. However, note that a mark from only one arch does not mean that it is not a biting injury. Characteristics, such as tooth size, shape, displacement, rotations, wear facets, etc. Differential Diagnosis It is important to remember that other injuries can mimic bite marks.
