This is particularly so if there is any question that the detainee may have recently ingested substances rosuvastatin 20 mg low cost, the full effects of which may not as yet be obvious buy 20 mg rosuvastatin with mastercard. Reassessment after a specific period should be recom- mended, depending on the history given by the detainee and the examination findings. It is good practice for all new substitute opiate prescriptions to be taken initially under daily supervision (11). In the custodial situation, if the detainee is on a super- vised therapy program, one can be reasonably sure the detainee is dependent on that dose; the detainee may of course be using other illicit substances as well. Recent urine test results may be checked with the clinic to see whether methadone or other drugs are detected on screening. Particularly with opiate substitution treatment, in the absence of with- drawal signs, confirmation of such treatment should be sought before autho- rizing continuation. The prescribed dose of opiate substitution therapy may not necessarily indicate accurately the actual amount taken each day if not supervised, because part or all of the dose may be given to other individuals. It should be remembered that giving even a small amount of opiates to a nondependent individual may be fatal. Cocaine abuse accelerates the elimina- tion of methadone; therefore, higher doses of methadone must be prescribed to individuals on maintenance regimes who continue to abuse cocaine (12). Any decision to prescribe should be made on the assessment of objective signs as opposed to subjective symptoms, and a detailed record of the history and examination should be made contemporaneously. Good practice dictates that where treatment can be verified, it should be continued as long as it is clinically safe to do so. Medical Complications of Substance Misuse Medical complications of substance misuse may give an indication of a problem in the absence of acute symptoms or signs of intoxication. Intrave- nous injection may result in superficial thrombophlebitis, deep vein thrombo- sis, and pulmonary embolus and chronic complications of limb swelling and venous ulcers. If injection occurs accidentally into an artery, vascular spasm may occur and result in ischemia, which, if prolonged, can lead to gangrene and amputation. Cellulitis and abscesses may be seen around injection sites, and deep abscesses may extend into joints, producing septic arthritis. Skin manifestations of drug addiction may be seen more commonly in opiate rather than stimulant users, even though stimulant users inject more frequently (14). This is partly because stimulants do not cause histamine release and, therefore, are seldom associated with pruritus and excoriations and also because cutaneous complications are frequently caused by the adulter- ants injected along with the opiates, rather than the drugs themselves. Fresh puncture sites, tattoos used to cover needle tracks, keloid formation, track marks from chronic inflammation, ulcerated areas and skin popping resulting in atro- phic scars, hyperpigmentation at sites of healed abscess, puffy hands (lymphe- dema with obliteration of anatomic landmarks and pitting edema absent), and histamine-related urticaria (opiates act on mast cells resulting in histamine release) may be seen. Opiate Intoxication and Withdrawal The characteristics of the medical syndromes in opiate intoxication, over- dose, and withdrawal are given in Table 4. Opiates, such as heroin, may be taken orally, more usually injected, or smoked—chasing the dragon. Chronic administration of opiate drugs results in tolerance (Table 5) to effects such as euphoria mediated by the opiate receptors and to the effects on the autonomic nervous system mediated by the noradrenergic pathways. Tolerance to heroin can develop within 2 weeks of commencing daily heroin use, occurs more slowly with methadone, and may go as quickly as it devel- ops. With abrupt withdrawal of opiates, there is a “noradrenergic storm,” which is responsible for many of the opiate withdrawal symptoms (Table 6). Cyclizine may be taken intravenously in large doses with opiates, because it is reported to enhance or prolong opioid effects, also resulting in intense stimulation, hallucinations, and seizures; tolerance and dependence on cyclizine may also result (17). Many opiate users are also dependent on ben- zodiazepines, and concurrent benzodiazepine withdrawal may increase the severity of opiate withdrawal (18). Substance Misuse 291 Table 4 Medical Syndromes in Heroin Users Syndrome (onset and duration) Characteristics Opiate intoxication Conscious, sedated “nodding”; mood normal to euphoric; pinpoint pupils Acute overdose Unconscious; pinpoint pupils; slow shallow respirations Opiate withdrawal • Anticipatory 3–4 h after Fear of withdrawal, anxiety, drug-craving, drug-seeking the last fix (as acute behavior effects of heroin subside) • Early 8-10 h after Anxiety, restlessness, yawning, nausea, sweating, nasal last fix stuffiness, rhinorrhea, lacrimation, dilated pupils, stomach cramps, increased bowel sounds, drug-seeking behavior • Fully developed 1-3 d Severe anxiety, tremor, restlessness, pilo-erection (cold- after last fix turkey), vomiting, diarrhea, muscle spasms (kicking the habit), muscle pain, increased blood pressure, tachycar- dia, fever, chills, impulse-driven drug-seeking behavior • Protracted abstinence Hypotension, bradycardia, insomnia, loss of energy and appetite, stimulus-driven opiate cravings From ref. Treatment of Opiate Withdrawal Symptomatic treatment of the opiate withdrawal syndrome can often be achieved using a combination of drugs, such as benzodiazepines for anxiety and insomnia; loperamide or diphenoxylate and atropine for diarrhea; promet- hazine, which has antiemetic and sedative properties; and paracetamol or non- steroidal antiinflammatories for generalized aches. Substitution treatment may be required in more severe cases of opiate dependence using a choice of methadone, buprenorphine, or dihydrocodeine. Because street heroin varies in purity, the starting dose cannot be accurately estimated on the basis of the amount of street drug used. Therefore, substitu- tion therapy should be titrated against the symptoms and signs of withdrawal. For example, dihydrocodeine may be commenced in a dose of 120 mg three times a day, with the dose being increased if the patient has demonstrable clinical signs of opiate withdrawal (19). Clonidine and lofexidine act as presynaptic α2-adrenergic agonists, which inhibit the noradrenergic storm associated with opiate withdrawal. Either of the following: • Cessation of (or reduction in) opioid use that has been heavy and prolonged (several weeks or longer) • Administration of an opioid antagonists after a period of opioid use B. Three (or more) of the following, developing within minutes to several days after Criterion A: • Dysphoric mood • Lacrimation or rhinorrhea • Nausea or vomiting • Diarrhea • Muscle aches • Fever • Pupillary dilation, piloerection, • Yawning or sweating • Insomnia C. The symptoms in Criterion B cause clinically significant distress or impairment in social, occupational, or other important areas of functioning. The symptoms are not due to a general medical condition and are not better accounted for by another mental disorder.

Te forensic odontologist is able to aid in the closure process for a grieving family (see Chapter 9) generic 20 mg rosuvastatin with mastercard. Te process of collection of dental information on victims in a mass disaster is identical to the processes that are used in the identifcation of a single fatality cheap rosuvastatin 20mg with mastercard. Te major diference in this process is the potential magnitude of the event and the unique set of circumstances that can surround the event. Tese may include the location, climate, and cover- age area of the event, for example, a plane crash in mountainous terrain, a tsunami in a tropical area, the collapse of multistory structures in a major city, or a hurricane in a coastal area. Each of these incidents has unique issues that must be addressed with regard to recovery, processing, and storage of remains. Personnel in all areas of the operation should have the ability and desire to be detail oriented, as errors can lead to missed or misidentifcations. A mass disaster team should be organized and trained in coordination with the local or state government to allow the most expeditious deployment of a dental team when its services are needed. Bitemarks can occur in a wide variety of substrates, although the most common of these is, unfortunately, human skin. Te proper documen- tation of a bitemark is not overly complex, and the techniques for collecting evidence are manageable by most forensic dentists with practice and atten- tion to detail. Te bite site can be evaluated in the third dimension by using a very accurate dental impression material and dental stones or resins to create a solid model for viewing under magnifcation, light microscopy, or with scanning electron microscopy. Tis three-dimensional model of the bitten area can then be compared to suspects’ dental casts. Technique shortcomings exist and include that solid models of bitemarks on skin are nonelastic. Te problems associated with bitemark analysis will be discussed more fully in Chapter 14. Healthcare practitioners are required by law in most jurisdictions to report suspected cases of abuse. Extraoral injuries consistent in shape and appearance to a hand or object are identifable. Intraoral trauma can occur as the result of strikes to the face, causing torn frena and fractured, mobile, or avulsed teeth. Intraoral sof tissue pathology may be noted following forced feeding or forced fellatio. Some cases may require the consideration of whether extensive or rampant caries are a result of the caregivers’ lack of knowledge or stem from neglect or abuse. In areas where access to dental care is an issue there will likely be a higher caries incidence that could further exacerbate the determination of whether reporting of abuse may be necessary. Deciding to report suspected abuse requires sound judgment, especially considering that the parent or scope of Forensic odontology 29 guardian may be the perpetrator. If a report is initiated, the ensuing investi- gation will be difcult for all concerned (see Chapter 15). Tese include developmental, histological, biochemical, and anthropological techniques. Anthropologists analyze the fusion of the cranial sutures of the skull, the development of the long bones, features of the pelvic girdle, and along with forensic dentists, features of the teeth. Tese techniques can be valuable when creating a profle for an unidentifed person, whether living or deceased. Estimating an individual’s age can also be helpful in assist- ing law enforcement agencies in determining the attainment of the year of majority of a living individual that will ultimately afect the individual’s treat- ment in the legal system as either a child or an adult. Te methods of age estimation using teeth include analyzing tooth devel- opment and eruption, studying tooth degradation, and measuring biochemi- cal and trace element changes in dental structures. Each of these methods has its advantages and limitations in accuracy and in the ease of use. Some can be performed through the analysis of dental or other radiographs or with clinical examination; others require laboratory testing or tooth destruction. Te individual jurisdiction’s requirements and the odontologist’s skill and knowledge will help to establish the appropriate techniques for each case (see Chapter 13). Te testimony may involve the previously mentioned areas of dental identifcation, bitemark analysis, or age estimation. Dentists participating in forensic casework should expect that at some point they will be required to provide sworn testimony. Forensic dentists also may be called to provide an opinion in standard of care, personal injury, dental fraud, or other civil cases. Tese cases, as with other forensic cases, require the evaluation of material and the develop- ment of an opinion concerning the case. Dental experts must be advocates for the truth and endeavor to fnd that truth by the application of their special knowledge and skills. Te unwavering goal of the forensic dental expert must be impartiality, thoroughness, and accuracy (see Chapter 16). For most who participate in the feld of forensic odon- tology there is not great fnancial reward, but the satisfaction of performing difcult and challenging tasks well is immensely rewarding. A forensic odon- tologist’s work can have great impact on the lives of individuals and families.

Research is limited at this point discount rosuvastatin 5mg otc, but it is widely used by naturopathic physicians 10mg rosuvastatin for sale. 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.
