Somewhat ironically quality cefpodoxime 100 mg infection game strategy, greater progress in the medical investigation of death may have occurred afer the barbarian invasions of Rome in the ffh century A generic cefpodoxime 200mg with amex antimicrobial diet. Tese invading tribes intro- duced the concept of the weregeld discount cefpodoxime 100mg on line antimicrobial quaternary ammonium salts, a type of compensation or “blood money” paid to the victim of a crime cheap cefpodoxime 100mg without a prescription antibiotics given for tooth infection, or his family, by the assailant. Medical experts were utilized to assist the court in conducting these examinations, as documented in the legal codes of the era. Later, in Charlemagne’s Capitularies, the requirement for medical testimony in certain types of traumatic injury was required, but afer the death of Charlemagne it seems that progress in death investigation languished in the West for some time. In an efort to ameliorate the village’s problems and confrm the culpability of a particular corpse, the grave of the recently deceased was sometimes opened. On exhuming the body, typical changes of decomposition would be noted as expected, though they were misinterpreted as indicating something much more menacing than the normal dissolution of the body. Tis is the issue of a dark bloody fuid from the oral and nasal passages due to autolysis, putrefaction, and liquefaction of the internal viscera. Te resultant fuid is pushed out of the nose and mouth through the airways and esophagus by decompositional gas formation, which causes increased pressure within the thoracic and abdominal cavities. Tough now recognized as a common postmortem artifact, this purging pro- cess was taken to represent blood soiling of the mouth due to recent feeding on the blood of living victims. Further, with decomposition, the epidermis of the skin separates from the underlying dermis, resulting in so-called skin slip. Rather than being recognized as a decompositional change, this slip- page of the skin was attributed to the growth of new skin, and decomposi- tional bloating and red discoloration of the body were described as a healthy, ruddy complexion, compared with the sallow appearance of the deceased at the time of burial. As decomposition progresses, rigor mortis (or stifening of the extremities) disappears, but this suppleness of the limbs was considered a sure sign of vampirism. All of these factors were taken to indicate continued life beyond the grave, as well as nocturnal feasting on the blood of the living occupants of the village. Detailed methods of investigation were developed in order to confrm the identity of the “vampire,” and there were also pre- scribed procedures for warding of the revenant, and for putting it to rest permanently. Tese included such treatments as decapitation, “staking” the vampire through the heart, removal of the heart, cremation, tying the mouth shut, and reburial face down, presumably to confuse the undead when he or she attempted to rise from the grave. It seems difcult to believe that such misconceptions could occur, particu- larly as the phenomenon of postmortem decomposition should have been well known (refrigeration of decedents not being available in that era), but such is the case. And even though the beliefs in vampirism were manifestly erroneous by today’s standards, they do indicate a depth of concern about the process of death. Tey also show the development of a detailed investigative and empiric method, and the development of an internally coherent and systematic way of explaining observations and understanding death and its relationship to other death investigation systems 35 occurrences. Such internally consistent and systematic misinterpretations based on the best learning of the day should serve to give us pause when we become too certain of the validity of our own current positions. Another example of early death investigation, from an Eastern perspective, can be found in the book Hsi Yuan Chi Lu13 [Te Washing Away of Wrongs] (from China, circa 1247 A. Tis text gives detailed instructions on death investigation, and is probably the oldest extant full text on the topic. It includes discussions of decomposition, determination of time since death, homicidal violence, self-inficted injuries, various accidental deaths, and deaths due to natural causes. In spite of its antiquity, the similari- ties between the investigational methods taught in the book and those utilized today are ofen striking. Te frst instance of an ofcial ofce charged with the investi- gation of death, as we know it today, was probably the English coroner. Tese itenerant judges traversed the land to hear cases and dispense justice, but due to the long intervals between their visits (an average of seven years), it was necessary to have local ofcials perform careful investigations and keep records of ofenses so that the cases could efectively be brought before the justices when they fnally did arrive. Tis would not do, as many of them involved production of revenues for the monarch, at that time Richard the Lionhearted. Richard, a Norman king, was an absentee ruler with a penchant for expensive foreign wars that placed a heavy strain on the royal cofers. In addition to his travels and the need to equip large numbers of troops, he also managed to become captured and imprisoned in Germany during his return from the Holy Land in 1192. Tese expenses created an acute need for revenues, so no stone was lef unturned in a desire to collect all taxes and other dues to which the Crown was entitled under the law. Tere were many such assessments, creatively applied in the name of law and order, to enrich the king at the expense of his subjects. Furthermore, villages were penalized with a fne, or amercement, whenever a murder or other legal infraction occurred in their jurisdictions, a punishment for allowing civil disturbances to occur or for not properly following the complex system of laws in the realm. Sometimes the victims of these murders were members of the conquering Norman class who were unfortunate enough to fnd them- selves in the midst of local Saxons bent on revenge. To prevent having large numbers of its Norman noblemen dispatched by the indigenous population, the Crown levied a fne known as the lex murdrorum on the lord of any village or territory in which a Norman was killed. Even the object actually causing a death (referred to as a deodand) was subject to presentation to the Eyre, and it could be confscated in the name of the Crown because of its culpability in the death or injury of a person. So if a person were injured or killed by a cart, animal, or farm implement, this item would likely be appropriated by the court, possibly depriving a farmer of the means of his livelihood. It is obvious that the king had a vested interest in making certain that all of these types of cases were properly investigated and documented to ensure that all potential revenues were discovered. Te law enforcement ofcers in each English county (shire) were the sherifs (from shire reeve), but many of these ofcers were Saxons. Not only were they less than enthusiastic about supporting the Norman king, but they also had a well-earned reputation for embezzlement, to the detriment of the Crown’s accounts, so another inves- tigative authority was needed to counter their authority in favor of the king. To this end, the twentieth Article of Eyre established the ofce of Custos Placitorum Coronae, or “keepers of the pleas of the Crown,” to represent the king’s interests in locales throughout the country. Te title coroner was a derivation of the Latin coronae for “crown,” or perhaps of the term crowner, one who represented the interests of the king. Originally these men were knights, men of some wealth and means (presumably to lessen their pro- pensity to embezzle funds), and their concern with death investigation was based entirely on the king’s fnancial interests. In addition to death investi- gation, they were responsible for investigating almost any aspect of life that could conceivably yield revenue for the king, including confscation of buried treasure and shipwrecks (“treasure troves”). In their pursuit of funds for the king (and themselves) coroners developed a reputation for greed and cor- ruption that approached that of the sherifs,17 so needless to say, they were not particularly popular with their local constituents. In later years, other ofcials, such as justices of the peace, took over much of the original investi- gative functions, while the coroners’ duties became focused exclusively on death investigation. Tey were empowered to hold public trials or “inquests,” death investigation systems 37 in which they questioned witnesses and empanelled juries to hear evidence regarding deaths and to make determinations as to how they came about. Te coroner’s inquest continues to persist today, and the ofce of the British coro- ner represents one of the oldest continuous judicial agencies in existence. During its colonial period, England exported much of its culture and legal system throughout the world, including the American colonies. Te governor of Maryland appointed a sherif-coroner in 1637, and the duties of the coroner are recorded in the state archives of that period. As the nation grew and developed, the ofce became an integral component of local governments, responsible for investigation of death in a particular jurisdiction, though the incumbents were tradition- ally not physicians. Unfortunately, some coroners developed reputations for bribery, embezzlement, and lack of integrity as part of the political “spoils” system, resulting in a relatively low public opinion of the feld. Early in the development of the coroner system, the lack of medical involvement in death investigation was of no consequence.

Moreover discount cefpodoxime 200 mg visa antimicrobial quartz, less tangible matters must not be overlooked in consid- ering persistence of beliefs discount cefpodoxime 200mg without a prescription infection breastfeeding, e 200mg cefpodoxime sale bacteria genus. Although such a mystique contributes to a ‘pedigree’ of empirical knowledge order cefpodoxime 100 mg without prescription antibiotic resistance microbiology, it must be pointed out that relatively few plants used by North American aboriginal peoples had a lasting impact on North American and European professional medical prac- tice – as distinct from domestic usage – which raises doubts about the general effectiveness of many of them, even black cohosh. As noted, not only is there a history of uncertainty, even when black cohosh was in fashion, but also there are issues over current promotion that selects information to support a case, or even over ‘reading’ uses into older texts to support current views on a substance’s reputation in menopausal symptoms. In the current climate of practice, a practitioner has a responsibility to provide the pros and cons for the use of a treatment giving a critical evaluation of non-scientific as well as scientific data. Magico-religious/spiritual practices Introductory comments As problematic as the critical appraisal of information on herbs can be, some practitioners may find greater difficulty in responding to queries about what have long been called magico-religious, magical and spiritual practices. Nowadays, the distinction between these categories is commonly blurred, because they depend on how supernatural forces are viewed by individuals. Although this chapter is not concerned with Mexican traditional prac- tices, they have become part of other North American countries to which Mexicans migrated. Magico-religious practices commonly embrace beliefs in supernatural influences; these include shamanism, in which a shaman, in the context of healing, can act as a medium for an entering spirit (maybe the spirit of a renowned ancestral healer) to ‘orchestrate’ the care through the healer. On the other hand, some will describe, say, the charming away of warts as merely ‘magical’, meaning a magical circumstance – a view perhaps influ- enced by a popular idea of a healer as someone who is able to help a person develop their own inherent healing powers, or, as some might say, enhancing ‘the power of the mind over the body’. The ‘power’ (or skill) of some such healers may be viewed as a result of a deep knowledge of traditions, perhaps including the ability to make spiritual connections – in other words, divorced from being able to control supernatural forces. It is incumbent on a practitioner responding to the question from a patient about a ceremony (perhaps an aboriginal person looking to reconnect with traditional ways) to appreciate the spectrum of ceremonies and how they may help with specific physical, mental or psychological problems. To do so 56 | Traditional medicine demands reflection on one’s own attitudes as well as an appreciation of the nature of the main ceremonies (step 1). It is certainly as well to remember that conventional medicine has long looked upon magical practices as lacking credibility, certainly since the seventeenth to eighteenth centuries when supernatural practices were increasingly expunged from regular treatments. In fact, this trend joined the growing scepticism, on the part of many practitioners, of the value of numerous herbal treatments including those used by aboriginal peoples. For instance, in 1897 James Mooney indicated that only 25% of an admittedly small group of Cherokee plants were used correctly (see Hamel and Chiltosky,18 page 6). Step 1 (preparation): the placebo effect Before noting some features of healing ceremonies (the sweat lodge as an example) that can be useful for a practitioner in discussions with patients, it is helpful to reflect on a reason commonly heard today for paying little attention to aboriginal treatments, namely that any benefit is ‘merely a placebo effect’. With this new role, physicians began to feel that it was unethical to prescribe a placebo consciously – as had previously been fairly common (the proverbial ‘bottle of coloured water’, although attacked at times) – either as ‘fake’ treatment or as one unsupported by clinical trial data. It is noteworthy that the change in attitudes from before the 1950s seemingly occurred without general discussion on the potential to diminish placebo effects that benefited patients. Having said this, it is as well to appreciate that, since writing this, some change in attitudes might be under way. At least a British Medical Journal editorial (3 May 2008) strongly hinted that the placebo effect may be one of the most ‘added value’ tools in the medical bag. This applies to healing ceremonies although they are often acknowledged to have poten- tial psychological effects for some participants, perhaps associated with the power of the ritual (see below). Moreover, many facets of healing ceremonies resonate with those viewed as essential for effective therapeutic relationships: Aboriginal/traditional medicine in North America | 57 mutually held beliefs between practitioner and patient, a patient’s trust, elements of hope and other factors with a potential to foster a placebo effect. Given this, a conventional practitioner may want to consider seriously whether to positively support a healing ceremony, or indeed for it to become a part of integrated care for an aboriginal person living in an urban situation and looking to try a traditional practice. The sweat lodge: some key points for step 2 discussion The sweat lodge is chosen to illustrate certain points that can be useful when responding to a patient who asks whether a healing ceremony might be helpful, as well as for exploring their expectations. The sweat lodge is where you can talk openly about how you feel about alcoholism, family abuse or whatever. Whenever you have difficulty, you know there will always be people in the circle who do care about you, and do care if you survive or not, and do care for your family. And, too, I’ve heard a lot of talk from older people on how it helps not only the spiritual part, but also aches and pains. These words from the chief of a Mi’kmaq reserve, where the sweat lodge ceremony was recently introduced (after being in limbo for generations) as part of the revitalisation of traditional ways and values, reflects both the widespread use of the lodge to help with sociomedical problems (e. Although details of the sweat lodge and ceremony are generally well known in outline, it is helpful to stress the beliefs and symbolism behind every stage in constructing a lodge and each step in the ceremony. A brief flavour is given in the following summary of the Mi’kmaq chief’s descrip- tion. This is similar to other accounts of sweat lodge ceremonies although there are many variations in detail such as differences in construction (from permanent to small low-level lodges), in details of the ceremony (e. Whatever the differences in detail, spiritual connections are borne in mind throughout the construction of a lodge and the ceremony. On one occasion, the chief’s brother saw an eagle fly down into a wooded area, but surprisingly it did not reappear. Given the symbolic nature of the eagle in aboriginal spirituality this was considered a sign of a spiritual place suitable for a lodge. Then, each step in 58 | Traditional medicine construction made connections to the spirit world or to the traditions and values of the past, e. Subsequent steps after closing the ‘door’ (flap) include: • creating steam by pouring water (sometimes a sacred water) on the hot rocks (viewed as helping to effect purification of the body and spirit) • prayers to the spirits said by the conductor of the ceremony • the participants – who are seated on the earth in a circle around the rocks – raising in turn personal or community issues. Although the conductor may not be a shaman, special ‘powers’ may be brought into a ceremony. Sometimes this is done in ways used only occa- sionally, perhaps throwing a particular herb or medicine on the heated rocks. One instance has been the use of ‘seven sorts’ medicine in sweat lodge ceremonies at the Conne River reserve. One oral account reported: One of the old-time favourite medicines is seven sorts – it’s like molasses. Put it on a cloth, like a plaster, for cuts, and aches and pains, but I’ve also used in the sweat lodge ceremony in a spiritual way by putting it on the hot rocks to become part of the steam; it helps to link with the traditional healing of the past. They were boiled together, the solid pieces removed, and the liquid boiled down to the thickness of molasses. The story of seven sorts is of special interest for its associations with magic, a reminder of the persistence of traditional practices generally viewed as folklore. The earliest recorded account of seven sorts is possibly in an 1896 article titled ‘Micmac Magic and Medicine’. The author states that it illustrates the ‘mystic’ of [Indian] medicinal herbs, the ‘magical’ associations were linked to the way the seven constituents were collected during a partic- ular season (in the autumn), the order of collection, and for the barks to be taken from particular sections of trunk when each was in sunlight; impor- tant, too, was the power attributed to the number seven. Ceremonies and healthcare institutions In addition to the sweat lodge, practitioners may be called on to comment on other ceremonies that have a strong healing component. Although it is beyond the scope of this chapter to detail these, practitioners should be prepared to follow up on a patient’s interest in any ceremony associated with healing. In so doing a practitioner may call on other sources of guidance – maybe programmes focusing on learning traditional ways such as building wigwams, trapping, etc. Team care can be important in many ways as when a patient wants a healing ceremony in a conventional health- care setting (hospital or surgery/clinic). It is not uncommon for an aboriginal person to first express interest in traditional ways when serious medical problems arise. Such a person may be too timid to ask directly for a cere- mony, but an empathic practitioner may sense the need. A not uncommon wish is for smudging, a ceremony recognised for ‘purification’ that can foster, at the very least, feelings of spiritual well-being.

Research is limited at this point purchase cefpodoxime 200mg amex antibiotic xanax, but it is widely used by naturopathic physicians. During puberty hormones called androgens trigger the sebaceous glands to grow and produce more sebum (oil). Irregular shedding of skin cells lining the hair follicle can lead to clumping and cause the pores to clog. A type of bacteria called Propi- onibacterium acnes, which normally lives in the skin, invades the clogged pore and begins to grow, creating inflammation and irritation. Most over-the-counter products contain salicylic acid, benzoyl peroxide, or sulphur. All of these products may cause redness, burning, stinging, and scaling of the skin. Creams and gels containing tretinoin (vitamin A derivative) or tazarotene (syn- thetic vitamin A) are used to slough off dead skin, clear pores, and dry acne. Accutane is an oral medication derived from vitamin A; it reduces sebum production and swell- ing, and minimizes acne-causing bacteria. It is effective, but must be taken for several months and may cause dry mucous membranes, muscle aches, and liver problems. It must be avoided by women who are pregnant or trying to conceive as it can cause severe birth defects. Antibiotics (tetracycline, erythromycin, or minocycline) are sometimes prescribed for mild to moderate acne. They work for some people, but their use is limited by side effects such as upset stomach, diarrhea, sun sensitivity, and yeast infections. Side effects include blood clots, bloating, cramps, spotting, liver and gallbladder disease, and increased risk of breast cancer. Top Recommended Supplements A Tea tree oil: A natural antibiotic and antiseptic; try a lotion or cream with 5–15 percent tea tree oil. Studies have found it just as effective as benzoyl peroxide, but it is better tolerated. Choose a supplement that also contains copper (3–5 mg) because chronic use of zinc can reduce copper absorption. Complementary Supplements B-vitamins: Deficiencies are associated with acne, so supplementing may reduce breakouts. Nourish your body and skin with a healthy diet, including lots of fibre, good fats, and water. These allergies occur when the immune system overreacts upon exposure to allergens, substances such as trees, A grass, or flower pollen. Some people have persistent, year-long allergies that are triggered by environmental factors such as house dust, mould, animal dander, dust mites, and air pollution. The immune system responds to these otherwise harmless substances as invad- ers, similar to how it would react to viruses or bacteria. It produces an antibody against the allergen called immunoglobulin E (IgE), which triggers the release of inflammatory chemicals—histamine, leukotrienes, and prostaglandins. Histamine is responsible for the notorious allergy symptoms of itchy, runny eyes and nose, and sneezing; leukotrienes cause excess mucus production; and prostaglandins trigger inflammation. Researchers do not completely understand why some people get allergies while others don’t, but there are a few theories. One is the overuse of antibiotics, which causes destruction of the normal flora (bacteria) in the gut. With little exposure to dirt and bacteria, our immune system is primed to respond when faced with a foreign invader. The name originated in the 1800s when British doctors found that people living in rural areas experienced sneezing and itching with exposure to cut hay or grass. This reaction caused nervousness, which was referred to as “fever,” hence the name “hayfever. Prolonged sinus congestion can increase the risk of sinusitis (infec- tion or inflammation of the sinuses). Antihistamines block histamine release and improve symptoms of itch- ing, runny nose, and sneezing. Benadryl (diphenhydramine) and Chlor-Tripolon are older antihistamines, which cause substantial drowsiness and are taken every six hours. Side effects include insomnia, racing heart, increased blood pressure, and irritability. Note: Decongestant nasal sprays can cause rebound congestion if used longer than three days. It is most effective as a preventative (before symptoms start) and is available in eyedrops and nasal spray. These injections contain purified al- lergen extracts, which desensitize you to allergies. Foods to avoid: • Mucus-forming foods such as dairy products, refined flours, and saturated and hydroge- nated fats can trigger inflammation and should be avoided. Top Recommended Supplements Aller-7: A combination of seven plant extracts that reduces allergy symptoms when taken regularly. Dosage: 660 mg twice daily for six to 12 weeks, then 330 mg twice daily thereaf- ter. Studies used a standardized extract providing 8 mg of petasine (an active chemical) three times daily. Nasaleze: A nasal powder that is inhaled and forms a barrier in the nostrils against allergens. It has no side effects or drug interactions and is safe for children and pregnant women. Sev- eral studies have shown that it reduces allergy symptoms and the need for medication. Complementary Supplements Moducare: A mixture of plant sterols and sterolins (plant fats) that helps balance the im- mune system. Probiotics: Help replenish gastrointestinal flora, which is important for immune function. Vitamin E: Has antioxidant effects and has been shown to reduce allergic response and nasal symptoms (sneezing, itching, stuffiness, and runny nose). Eat plenty of antioxidant-rich fruits and vegetables, especially garlic, onions, and A peppers, nuts, and seeds.

Tis step-wise replication of the template strand starts at one primer and continues nucleotide by nucleotide until the ending primer is reached. Tis gel may be poured into an external slab or run inside a single or multiple capillaries (an array). Te older slab gel confguration risked bleed-over from one injection lane to the next and took much longer for a technician to prepare. Te newer capillary arrays are cleaner and more efcient but also more expensive (Figure 7. At that point a laser detects the fuorescent signal and correlates it to a standard (allelic ladder) of known fragment sizes. Pairs of peaks usually indicate heterozygosity at that location (locus) on the molecule, whereas a single peak generally indi- cates the individual is homozygous or has only one variant at that locus. Tese nucleotides are unique in that they are missing the 3′-hydroxyl group that would normally permit the extension process to continue. Instead, the incorporation of this dideoxynucleotide terminates the extension process. Although normal deoxynucleotides are also present, only the dideoxy terminators are fuorescently tagged with one of four dye colors for adenine, guanine, cytosine, and thymine. Subsequently, when the strands are sorted according to length, the instrument will compute the actual sequence of the original amplicon. Most laboratories require a minimum of two experienced analysts to review all these data prior to conclusions being reported. It is also the exclusive purview of the analyst to compare data between two samples, draw a conclusion, and to calculate the statistical weight of the opinion. Te community adheres to a con- sistent application of quality assurance measures that include the delineation of roles and responsibilities of laboratory management, minimum education requirements for laboratory staf, established standards for training, annual profciency testing, guidelines for the validation of new equipment and tech- nologies, and mandatory components for inclusion in the fnal report. Federal, state, local, and even commercial laboratories all began to adapt their operations to accommodate these standards. Current national standards require annual audits with a mandatory external assessment in alternating years. Any concerns associated with the qualif- cation of laboratory staf or past audit results should be resolved well before large amounts of critical evidence are submitted to the laboratory. Te technology is very precise and can individ- ualize extremely small fragments of bones and tissue. But, the same exquisite capacity for detailed analysis is counterbalanced by a high cost in both time and material resources. And, given these challenges and their inherent potential for delaying fnal case resolution, repa- triation of the victims’ bodies, and family notifcation, where does the case dna and dna evidence 115 manager draw the line as to how much evidence to test? Federal, state, and local government laboratories operate on very tight budgets that are tied directly to current-day political and legislative priorities, notwithstanding their busyness with respect to ongoing casework. Although appropriations will rise and fall, no government labo- ratory is funded to maintain excess capacity in the of chance that a mass fatality incident might occur in the future. In a like manner, commercial laboratories have a proft margin to maintain, and although some are quite good at expanding capacity on short notice, there will generally be a delay and some need for immediate funding to cover the expenses of a productivity surge. Meeting with laboratory representatives to confrm their willingness to be part of a mass fatality contingency is essential. In some circumstances, the very same disaster that they plan to help address could compromise their own facility, and thus the ability to support any relief efort. If more than one laboratory is included in the disaster plan, authorities should host a meeting between technical representatives so that communication, evidence transfer, data interpreta- tion, anticipated expenses, and turnaround times, as well as compatibility of typing systems and instrumentation, are agreed upon well in advance. As soon as possible, however, the disaster response plan must be applied and the journey away from chaos will begin. One of the most signifcant decisions made by local authorities involves the scope of the medicolegal death investigation. Essentially, a deci- sion must be made regarding whether the identifcation of all biological material recovered will be sought versus the more direct goal of establish- ing each victim’s identity and a frm cause and manner of death for those involved. Government and elected ofcials, families of the victims, the media, and even the laboratory staf themselves will ebb and fow between resolve, compassion, and frustration. Establishing realistic expectations in the beginning, even if they seem pessimistic or unpopular, will purchase more patience and credibility as the postevent investigation wears on. Some odontologists will empathize with this challenge, knowing that in clinical dental cases dental laboratories must rely almost exclusively on the infor- mation submitted on the work request form. Depending on the quality and experience of the dental laboratory, if the clinician submits poor or incom- plete information or fawed casts or impressions, then the lack of clarity will certainly be refected in the fnal product. Unfortunately, the surge in samples and the unrelenting public call for imme- diacy will complicate the communications efort even further. Team members may also be required to select the best possible material from each of numerous fragmented human remains in order to provide a primary identifcation or the genetic basis for reassociation of body parts. Most fre- quently, natural disasters tend to require the former approach to sampling, whereas transportation accidents and terrorist events are more likely to have a greater need for reassociation. Tey must understand the criticality of the anatomical description and the unique numbering of samples, plus be able to handle a Stryker saw, tissue forceps, and scalpel with skill and safety. Odontologists and anthropologists are usually good choices for the collection team, but death investigators and emergency medical personnel are good alternatives. Te trauma surround- ing the event and subsequent environmental conditions will adversely afect the sof tissue frst by fragmentation and later by decomposition. Although skeletal muscle is an easy sample to collect at the morgue and relatively simple to process at the laboratory, the condition of the remains may necessitate the collection of samples of bones and even teeth instead. Clumps of hair, skin faps, and sof tissue that are predominantly composed of adipose tissue all cause additional steps in laboratory processing and should be avoided when possible. Tissue, bone, or tooth samples should be placed in a secure container without any preservative. Urine specimen cups may leak, glass containers could break, and small plastic bags are subject to puncture. Conical tubes with screw caps easily accommodate 5 to 25 g samples of sof tissue, bone, or tooth, do not leak, and have a smooth exterior surface for handwritten or adhesive labels. Plus, enforcing their use actually limits the amount of sample that an overly enthusiastic anthropologist, odontologist, or pathol- ogist can submit from a single source. Tis reduces the long-term storage 118 Forensic dentistry requirements of the laboratory and forces the collection team to focus on the selection of the best quality material while reducing unnecessary cutting of the remains. Te family members that appear at the Family Assistance Center are not always the best genetic candidates for family references. Furthermore, most out-of-town family members may not linger long afer the initial event. For these reasons, as much information regarding the victim’s genetic tree and the whereabouts of other relatives must be obtained on the frst interview with the next of kin.
