A report may be required for a variety of reasons order sildenafil 75 mg without a prescription, and its nature and content must be directed to the purpose for which it is sought 50mg sildenafil with visa. Is it a report of the history and findings on previous examination because there is now a crimi- nal prosecution or civil claim? Is it a request to examine the patient and to prepare a report on present condition and prognosis? Is it a request for an expert opinion on the management of another practitioner for the purposes of a medical negligence claim? The request should be studied carefully to ascertain what is required and clarification sought where necessary in the case of any ambiguity 25mg sildenafil with amex. The fee or at least the basis on which it is to be set should also be agreed in advance of the preparation of the report generic 50mg sildenafil mastercard. If necessary sildenafil 25 mg low cost, the appropriate consents should be obtained and issues of confidentiality addressed. A medicolegal re- port may affect an individual’s liberty in a criminal case or compensation in a personal injury or negligence action. A condemnatory report about a profes- sional colleague may cause great distress and a loss of reputation; prosecuting authorities may even rely on it to decide whether to bring homicide charges for murder (“euthanasia”) or manslaughter (by gross negligence). Reports must be fair and balanced; the doctor is not an advocate for a cause but should see his or her role as providing assistance to the lawyers and to the court in their attempt to do justice to the parties. It must always be conisdered that a report may be disclosed in the course of legal proceedings and that the author may be cross-examined about its content, on oath, in court, and in public. A negligently prepared report may lead to proceedings against the author and perhaps even criminal proceedings in exceptional cases. Certainly a civil claim can be brought if a plaintiff’s action is settled on disadvantageous terms as a result of a poorly prepared opinion. The form and content of the report will vary according to circumstances, but it should always be well presented on professional notepaper with relevant dates and details carefully documented in objective terms. Care should be taken to address the questions posed in the letter of instructions from those who commissioned it. If necessary, the report may be submitted in draft before it is finalized, but the doctor must always ensure that the final text represents his or her own professional views and must avoid being persuaded by counsel or solicitors to make amendments with which he or she is not content: it is the 54 Palmer doctor who will have to answer questions in the witness box, and this may be a most harrowing experience if he or she makes claims outside the area of expertise or in any way fails to “come up to proof” (i. In civil proceedings in England and Wales, matters are now governed by the Civil Procedure Rules and by a Code of Practice approved by the head of civil justice. Any practitioner who provides a report in civil proceedings must make a declaration of truth and ensure that his or her report complies with the rules. Additionally, the doctor will encounter the Coroners Court (or the Procurators Fiscal and Sher- iffs in Scotland), which is, exceptionally, inquisitorial and not adversarial in its proceedings. A range of other special courts and tribunals exists, from eccle- siastical courts to social security tribunals; these are not described here. The type of court to which he or she is called is likely to depend on the doctor’s practice, spe- cialty, and seniority. The doctor may be called to give purely factual evidence of the findings when he or she examined a patient, in which case the doctor is simply a professional witness of fact, or to give an opinion on some matter, in which case the doctor is an expert witness. Usually the doctor will receive fair warning that attendance in court is required and he or she may be able to negotiate with those calling him or her concerning suitable dates and times. Many requests to attend court will be made relatively informally, but more commonly a witness summons will be served. A doctor who shows any marked reluctance to attend court may well receive a formal summons, which compels him or her to attend or to face arrest and proceedings for contempt of court if he or she refuses. If the doctor adopts a reasonable and responsible attitude, he or she will usually receive the sympathetic understanding and cooperation of the law- yers and the court in arranging a time to give evidence that least disrupts his or her practice. However, any exhibition of belligerence by the doctor can induce a rigid inflexibility in lawyers and court officials—who always have the ability to “trump” the doctor by the issuance of a summons, so be warned and be reasonable. A doctor will usually be allowed to refer to any notes made contemporaneously to “refresh his memory,” although it is courteous to seek the court’s agreement. Demeanor in Court In the space available, it is not possible to do more than to outline good practice when giving evidence. Court appearances are serious matters; an individual’s liberty may be at risk or large awards of damages and costs may rely on the evidence given.

Oscar Amoëdo—The Bazar de la Charite, 1898 Considered by many to be the father of forensic odontology, Dr. He began his studies at the University of Cuba, continued at New York Dental College, and then returned to Cuba in 1888. He became a dental instructor and teacher at the Ecole Odontotechnique de Paris in 1890 and rose to the rank of professor, writing 120 scientifc articles on many topics (Figure 2. A tragic fre at a charity event, the Bazar de la Charité, stimulated his interest in dental identifcation and the feld of forensic odontology. Amoedo was not involved in the postfre identifca- tions, but knew and interviewed many who were. His thesis to the faculty of medicine, entitled L’Art Dentaire en Medicine Legale, earned him a doctorate and served as the basis for his book by the same name, the frst comprehen- sive text on forensic odontology (Figure 2. His accounts of the identifcations following the Bazar de la Charite were given in a paper at the Dental Section of the International Medical Congress of Moscow and published in English in 1897, one year before the book was published. In that paper he revealed that neither a dentist nor physician generated the idea of dental identifcation: “It was then that M. In the face of the powerlessness of the legal doctors, since all ordinary signs of identifca- tion had disappeared, our confreres were appealed to … Drs. Te dentist complained about how strenuously and thoroughly the defense attor- ney grilled him while he was on the witness stand. Te stairways had been closed and chained to prevent the “lower-class ticket holders” from coming downstairs. Also, the out- side doors opened inward, a popular design of the day, but one that proved disastrous when frightened throngs pushed others against the doors, prevent- ing their opening. Cigrand stated in his article that “hundreds” were “unmistakably identifed” from their dental records. In the 1905 case in Germany, a robber bit into the cheese then lef it on a windowsill. Te store worker was arrested, but requested in court that his mouth be examined again, revealing that he had a broken tooth, the crown was missing, leaving only the root. Residents of the small village of Caleu mistook a group of German tourists for bandits and, fearing an attack, fred upon them. In the ensuing disagreements with German ofcials, the German consulate in Valparaiso was set on fre. Shortly afer this fre, the German litigation building in Santiago burned to the ground. William Becker, according to clothing, a wedding ring (with his wife’s initials in it), a watch, and glasses. Two German 20 Forensic dentistry physicians, members of the faculty of Santiago University, performed a second autopsy. Te anterior teeth were severely burned, but the posterior portion of the remaining dentition was described and charted. During this time, news was given that a consid- erable amount of money was missing from the consulate. A Chilean dentist was then asked by a judge in the case to examine the body and any pertinent records. Becker may have murdered him, dressed him with his own clothes and personal efects, and burned the anterior portion of his face to hide the fact that the secretary had gold bridgework. Law enforcement ofcials were alerted and the sec- retary was captured at a border crossing, trying to escape into Argentina. Becker was able to travel from Santiago into the mountains by wearing dark glasses and a handkerchief, hiding his identity by simulating a toothache. Tis eased the problems between Chile and Germany, and the relationship between the two nations was repaired. He num- bered permanent teeth from one to eight from the anterior midline and dis- tinguished the quadrants by placing the numbers in segments of a cross.

Drainage of semen from the vagina may also result in soiling of intimate clothing items worn at the time discount sildenafil 50 mg without prescription, and these can prove valuable sources of body fluids discount sildenafil 75mg online. It has been observed that spermatozoa can be isolated for longer periods in the endocervix generic sildenafil 50 mg without prescription. Studies that compared paired swabs from the vagina and cervix have found that 2 days or more after vaginal ejaculation there is a larger quantity of spermatozoa on endocervical swabs compared with the vaginal swabs (115) discount sildenafil 75 mg fast delivery. Therefore sildenafil 100mg lowest price, it is recommended that if a complainant presents 48 hours or more after alleged vaginal intercourse, an endocervical swab be taken in addition to the swabs from the vagina. There is interest in the possibility of determining the timing of inter- course by changes in spermatozoa. Spermatozoa may remain motile in the vagina for up to 24 hours and longer in the cervical mucosa (50,118,119), but the periods for persistence are extremely variable. For example, Rupp (120) observed that motile spermatozoa persisted longer in menstruating women but added that identification is hindered by the presence of red blood cells, and Paul (121) reported that the period of spermatozoa motility ranged Sexual Assualt Examination 91 from 1–2 hours at the end of the menstrual cycle to as long as 72 hours at the time of ovulation. However, the morphology of the spermatozoa does show more consis- tent temporal changes. In particular, the presence of large numbers of sperma- tozoa with tails is indicative of recent intercourse. The longest time after intercourse that spermatozoa with tails have been found on external vaginal swabs is 33 hours and 120 hours on internal vaginal swabs (122). Examination Methods The forensic practitioner should inspect the mons pubis and note the color, coarseness, and distribution (Tanner stages 1–5) of any pubic hair. A note should also be made if the pubic hair appears to have been plucked (including bleeding hair follicles), shaved, cut, or dyed. Then the vulval area must be carefully inspected before the insertion of a speculum, because even gentle traction on the posterior fourchette or fossa navicularis during a medical examination can cause a superficial laceration at these sites. Whenever possible, the vagina and cervix should be inspected via the transparent speculum after the high vaginal samples have been ob- tained. Colposcopy and the application of toluidine blue dye are two special- ist techniques used by some forensic practitioners during female genitalia examinations. Colposcopy A colposcope is a free-standing, binocular microscope on wheels that is most commonly used for direct visualization of the cervix (using a bivalve speculum) after the detection of abnormal cervical cytology. Many centers, particularly those in the United States, advocate the use of the colposcope for external and, where relevant, internal genital and/or anal assessments of com- plainants of sexual assault. The colposcope undoubtedly provides considerable advantages over gross visualization. First, it provides magnification (5–30 times) and greater illumi- nation, enabling detection of more abnormalities. Slaughter and Brown (123) demonstrated positive colposcopic findings in 87% of female complainants of nonconsensual penile penetration within the previous 48 h, whereas gross 92 Rogers and Newton visualization has historically identified positive genital findings in only 10– 40% of cases (37–39,124,125). Second, with the attachment of a still or video camera, the colposcope allows for a truly contemporaneous, permanent video/photographic record of the genital/anal findings without resorting to simultaneous dictation, which has the potential to distress the complainant. If a video is used, it will docu- ment the entire genital examination and will show any dynamic changes, such as reflex anal dilatation. If appropriate, the medical findings can be demon- strated to the complainant and carer; some teenagers have apparently appreci- ated the opportunity to have any fears of genital disfigurement allayed by the use of this equipment. Finally, if a remote monitor is used, the whole examination can be viewed by another doctor for corroboration or teaching purposes without additional parties having to be present during the intimate examination. Obviously, it is important that in all cases the colposcopic evidence be interpreted in the context of the limited information that is currently available regarding colposcopic assessments after consensual sexual acts (90,126,127). Toluidine Blue Toluidine blue stains nuclei and has been used on the posterior fourchette to identify lacerations of the keratinized squamous epithelium that were not apparent on gross visualization (128,129). Use of toluidine blue increased the detection rate of posterior fourchette lacerations from 4 to 58% in adult (older than 19 years) complainants of nonconsensual vaginal intercourse, from 4 to 28% in sexually abused adolescents (11–18 years old), and from 16. The same frequency of posterior fourchette lacerations has been identi- fied by use of the stain in adolescents after consensual penile penetration and nonconsensual sexual acts (129). In contrast, adult complainants of nonconsensual vaginal intercourse and sexually abused children had signifi- cantly more lacerations demonstrable by toluidine blue staining than control groups (130), although such staining does not identify lacerations that cannot be detected using a colposcope (123). Therefore, if a colposcope is not avail- able, toluidine blue may be an adjunct to the genital assessment of prepubertal and adult complainants of vaginal penetration (129,130). Furthermore, some centers use the stain during colposcopy to provide a clear pictorial presenta- tion of the injuries for later presentation to juries (123). Toluidine blue (1%) is then painted on the posterior fourchette, using Sexual Assualt Examination 93 a swab, before any instrumentation. After a few seconds, the residual stain is removed with lubricating jelly and gauze (128).
