Most modern digital cameras and traditional photographic flms are specifcally designed to record images seen in the visible range of light as we see them However order 2 mg estrace otc menopause urinary frequency, it is also possible to record images we cannot see when specifcally illuminated in the shorter ultraviolet range (210 to 400 nm) and longer infrared range (750 to 900 nm) buy estrace 2 mg amex menopause emotions. Since ultraviolet and infrared radiations are outside the visible range of the spectrum cheap 2 mg estrace overnight delivery pregnancy hormone levels, they are commonly referred to as nonvisible light estrace 1 mg cheap menstrual calculator. Recent genera- tions of digital cameras have been designed to allow the recording of pat- terned injuries in skin using both visible light and nonvisible light. While the electronic transfer of light to magnetic recording media is very diferent than exposing photographic flm, for the most part, the techniques utilized for image capture are basically the same. Photography using nonvisible light requires special techniques to record the injury, including an occasional minor focusing adjustment called focus shif3 that provides correction for the optical properties of lenses that were designed primarily to be used for visible light photography (Table 11. It is this refection of visible light that accounts for the colors seen by the human eye. It is the absorption of all colored light by an object that makes that object appear black. A third reaction that occurs, especially when light strikes human skin, is the transmission and scattering of the energy associated with the light through successive layers of cells until the energy of the light is spent and has dissipated. Te fnal reaction, which occurs when light energy strikes an object, is a molecular excitation called fuorescence (Figure 11. Molecules in tissue absorb the energy from light and release that energy as a fuorescent glow. It only lasts as long as the light’s excitation energy is applied, usually about 100 nanoseconds (10–9 seconds). When light energy of various wavelengths strikes human skin, all four of the previously mentioned events can occur simultaneously. Depending on the wavelength of the source of the incident light and the confguration of the camera, lenses, and flters, it is possible to record, individually, any of the four reactions of skin to light energy (Figure 11. Ultraviolet light only penetrates a few microns into skin, whereas infrared light can penetrate skin to a depth of up to 3 mm. By varying the wavelength of incident light used for illumination and setting up the appropriate confgu- ration of the camera, lens, flters, and flm, it is possible to photograph any of the four events that occur. Tis ability creates an opportunity for interest- ing pictures, especially when looking at bruises and other injuries to skin. Sharp surface details can be seen with ultraviolet light, while images well below the surface of the skin can be seen using infrared light. Images created using refected visible light and fuorescence allow other potentially diferent appearances of the patterned injuries to be captured. Te techniques and photographic protocols for documenting injuries to human skin in visible and nonvisible light using flm and digital imaging are vastly diferent. Tese changes from normal to injured to healing states allow discriminatory recording of the contusions illuminated by light sources of various wavelengths. Since the healing process is long term and ongoing, it is sometimes possible to photograph an injury afer that tissue appears to have healed to the naked eye. Similarly, photographing the same injuries over time using both visible and nonvisible light techniques can yield diferent appear- ances of those injuries, which can sometimes add to their evidentiary value (Figures 11. Success in photographing healing bruises over time will depend on sev- eral variables, including the composition of the injured skin, the thickness of the skin, the wavelength and intensity of light used to photograph the damaged area, the equipment used, and the type of flm used. Depending upon the specifc injury, it may be necessary to photographically capture the injuries digitally or with flm, in color and black and white using visible light, as well as nonvisible light. Te injury may also vary in appearance in the photographs of each of these incident light sources and over time if photo- graphed serially. Te location and type of skin injured has profound efects on the ability to photograph the injuries. For example, thick skin of the palm of the hand is usually much easier to photograph immediately afer an injury than afer it has partially healed. Te thick, keratinized covering of the palm of the hand ofen exceeds the ability of most light energy to penetrate enough to record Forensic dental photography 209 Figure 11. Series of photographs showing the appearance of a bitemark on the hip of a sexual assault victim. Note the sig- nifcant increase in the detail of the bitemark discernable in this ultraviolet image. Such cases require fuorescent photography due to the highly fuorescent nature of thick skin. In contrast, thin skin found in areas such as the face or female breast tissue can frequently lend itself to recording injury patterns long afer the visible damage from the injury has faded when viewed under room lighting with the naked eye. Again, this is directly related to the ability of the specifc wavelength light energy to react with the skin to a sufcient depth to record the injury. Forensic dental photography 211 It is important to understand a fnal concept about the physiology of injured skin. In a living victim, at any point in time afer the initial response to injury occurs, the composition of the injured skin is diferent from all other points in time; the skin is continuously changing as the injury heals. Tese changes will afect the response of the tissues to the selected wavelength of light energy over time and may change the appearance of the injured tissue when photographed. Tis is especially true in a living victim but it is also true in a deceased victim, for the frst few days afer death. If the anticipated photographic evidence is not obtained with the frst attempts, one should continue to rephotograph the injuries over time. If the victim is deceased, one should attempt to have the medical examiner or coroner delay any invasive autopsy procedures of the tissues associated with the injury until all attempts to photograph the injury have been exhausted. As previously mentioned, preserv- ing the detail of the injury with photographs may involve a combination of color and black-and-white visible light photographs as well as the use of the nonvisible ultraviolet and infrared photographs. Te photographer should develop a standard technique that includes capturing orientation photographs showing where the injury occurred on the body. Additionally, this protocol should include taking closeup photographs with and without a scale. Te scale serves as a reference to record the relative size of the injuries in the photographs. Tomas Krauss) for the purpose of minimizing photographic distor- tion and ensuring accuracy in measurement (Figure 11. Te photographer should retain the scale used in the photograph should enlargement to life-size reproductions become necessary at some future time. It is essential that the standard technique developed by the forensic photographer include exposing many photographs for each case. One should not be hesitant to use several rolls of flm or create signifcant numbers of digital images for a photo shoot. Manufacturers of flm-based and digital photographic equipment develop and market equipment and supplies that are specifcally designed to have an optimal performance in the 400 to 760 nm range of the electromagnetic spectrum. For the photographer wishing to take pictures in this range of light energy, there is little practice required to ensure highly detailed and sharply focused photographs. By defnition, the object to be photographed is viewed through the lens and the camera automatically adjusts the focus and exposure variables before image capture. Tese types of cameras have been manufactured for optimal photography in the visible light spectrum. Part of that manufacturing process includes coated lenses and fltered fash units that block out the unwanted segments of the nonvisible light spectrum. Most 35 mm cameras have serious size limitations when it comes to recording life-size images. Tis limitation comes from the restricted emul- sion area exposed on the flm (24 × 35 mm rectangle) or the small surface area used in the digital capture device. Since there are very few objects that will ft into that small of an area, considerable enlargement of the photographs may Forensic dental photography 213 Figure 11.

Chronic diarrhea can occur due to digestive disorders or use of medications that affect bowel function buy estrace 1mg amex premier women's health boca raton. Aside from being unpleasant and embarrassing order estrace 2 mg overnight delivery women's health lose 10 pounds, diarrhea can lead to serious com- plications such as dehydration and nutrient deficiencies cheap estrace 1mg with mastercard menstrual vacuum. In some cases it will clear up on its own 2mg estrace breast cancer uggs pink ribbon, and in other cases treatment is necessary to get it under control and prevent complications. However, to prevent dehydration, your doctor will advise you to increase fluid intake. There are special rehydration solutions, such as Gastrolyte and Pedialyte, available in pharma- cies, that contain electrolytes (salt, potassium, and other minerals) that are necessary for health and to prevent dehydration. If you become depleted in these nutrients, it can lead to heart problems and other consequences. Antibiotics destroy both the good and bad bacteria, which can dis- turb the balance of your normal flora in your intestine, leading to overgrowth or potentially dangerous bacteria, such as Clostridium difficile, which can cause very serious diarrhea and requires medical treatment. If lactose intolerance is causing the diarrhea, you will be advised to avoid dairy products or to take lactase (enzyme needed to digest lactose) when eating dairy. There are over-the-counter anti-diarrheal medications, such as Imodium (loper- amide), which can help to slow the diarrhea. However, these drugs should not be used if you have infectious diarrhea as they can prevent your body from eliminating D the offending organism. One study of 41 infants with diarrhea found that carob powder (at a dose of 1 g per kilogram per day) significantly improved resolution of diarrhea as compared to placebo. Teas containing chamomile or blackberry, blueberry, or red raspberry leaves can be helpful in alleviating diarrhea because these herbs contain tannins, which have astringent properties. As you start to feel better, eat foods that are nutritious and easy to digest, such as bananas, brown rice, and pota- toes. When your bowel movements have normalized, add more fibre-rich foods back into your diet. Foods to avoid: • Caffeine, alcohol, and spicy foods (hot peppers) are too stimulating to the digestive tract. Fruit juices (especially apple and pear) are high in sugar and should be minimized until you have recovered. Signs of dehydration include excessive thirst, dry mouth or skin, little urination, severe weakness, dizziness or lightheadedness, or dark urine. Signs of dehydration in infants include dry mouth, crying without tears, unusual sleepiness, sunken eyes or cheeks, and skin that doesn’t flatten if pinched and released. Top Recommended Supplements D Multivitamin and mineral complex: Persistent diarrhea can lead to deficiencies of vari- ous vitamins and minerals, and taking a multivitamin can help prevent deficiencies. Certain nutrients (such as folic acid and zinc) can promote healing of the intestine. Speak to your pharmacist or health adviser for a recommendation as products vary depending on age, activity level, lifestyle, and gender. Probiotics: Regular use of these beneficial bacteria can help prevent traveller’s diarrhea and also help treat infectious diarrhea. Over 13 clinical studies have shown that probiotics can reduce the severity and duration of diarrhea and help prevent it from occurring. Look for a product that provides at least one billion live cells per dosage and is stable at room temperature, such as Kyo-Dophilus. To prevent antibiotic-induced diar- rhea, take your probiotic when you start your antibiotic and for at least two weeks after the antibiotic is finished. Complementary Supplements Brewer’s yeast: Some research has shown that this supplement can help relieve infectious diarrhea, particularly when caused by Clostridium difficile (associated with antibiotic use). Goldenseal: Has antibiotic properties and contains a chemical called berebine, which pre- vents infectious bacteria from attaching to the gut and blocks the action of toxins produced by bacteria. To reduce your risk, avoid tap water and ice cubes and drink only bottled water and beverages; avoid raw fruits and vegetables unless you can peel them yourself; avoid raw or undercooked meats; use bottled water to brush your teeth; and keep your mouth closed while showering. Tak- ing a probiotic (friendly bacteria) every day while away can also help reduce the risk 208 of traveller’s diarrhea. These beneficial bacteria (such as lactobacilli and bifidobacteria) normally live in the colon and inhibit the overgrowth of disease-causing bacteria. See your doctor if diarrhea persists beyond five days or if you develop dehydration. Diverticula usually develop when weak places in your colon give way under pressure, causing the formation of pouches, which can protrude through the colon wall. These pouches rarely cause problems, so people often don’t realize that they have them. However, if the diverticula become infected (diverticulitis), this can cause abdominal pain, fever, nausea, and change in bowel habits. It is possible to prevent diverticular disease by eating a high-fibre diet and avoid- ing constipation. If diverticulitis occurs, it can cause: • Abdominal pain (severe and sudden onset) • Constipation or diarrhea • Fever, nausea, vomiting • Rectal bleeding Note: Complications of diverticulitis include blockage in the colon and abscess or fistula formation. If a pouch ruptures, the waste material can spill into the abdominal cavity, leading to peritonitis, which is a serious medical problem that needs immediate attention. Prior to the 1900s when refining of grains started, diverticular disease was rare in North America. A high-fibre diet can reduce your risk of diverticular disease and also help prevent flare-ups in those who already have it. For those with mild symptoms, dietary changes and antibiotics for the infection may be all that is needed. During a flare-up, your doctor will advise a temporary low-fibre diet to allow the colon to heal. Surgery is a last resort, but may be necessary for those with bowel obstruction or severely damaged intestine. Foods to avoid: • Fast foods and processed foods contain chemicals that can damage intestinal health. In the past, those with diverticular disease were told to avoid nuts or seeds, but there is no evidence that these foods trigger flare-ups, so they can be enjoyed as part of a healthy diet. Avoid holding it in as that can create dry, hard stools that are hard to pass, increasing colon pressure. Top Recommended Supplements Fibre: Helps prevent constipation and improve bowel function. One study of glucomannan, a water-soluble dietary fibre derived from konjac root, found that it reduced symptoms of diverticular disease. Probiotics: Beneficial bacteria help to reduce the risk of gut infection and also aid digestion and nutrient absorption. Dosage: Take one to three capsules daily of a product that provides at least one billion live cells. Include healthy fats (fish and flaxseed) and fermented milk products (yogurt and kefir) in your diet. Ear infections, known medi- cally as Otitis Media, are a non-contagious infection of the middle ear, just behind the eardrum. If the middle ear becomes inflamed from the infection, fluid builds up behind the eardrum, creat- ing a breeding ground for infection. These infections can also occur when there is swelling or problems with the eustachian tubes (the tubes that connect the middle ear to inner nose).
