Rakich or veterinarians with a strong interest in treating companion birds, the advantages of incorporating avian medicine into the small C H A P T E R F animal practice are numerous. With only minimal equipment additions and some intense con- tinuing education with the desire to learn, the prac- titioner can increase patient diversity and practice volume and be introduced to the challenge of avian diagnostics and therapeutics. Veterinarians with limited experience in treating birds should be realistic about their expertise and be ready to refer complicated cases that require advanced diagnostic, surgical or therapeutic techniques. A veterinarian may adver- tise a special interest in birds, but use of the word Cathy Johnson-Delaney “specialist” is reserved for only those who are board certified in avian practice. Attending aviculture seminars, visiting established avian practices and teaching bird handling skills to staff and colleagues are other good ways for begin- ning avian veterinarians to increase competence. Avian veterinarians in one city improved the care available to local avian patients by providing a train- ing program and procedure manual for emergency clinicians in the area. The sale of formulated diets, nutritional supple- ments and avian care accessories (hemostatic agents, grooming aids, carriers), helps to demonstrate the clinic’s dedication to the total well-being of compan- ion birds. Alternatively, local pet retailers may be informed of a veterinarian’s recommendations for diets and other avian products, and clients may be referred to those shops whose policies and products meet with established standards (Figure 7. Advertising in the yellow pages or other local busi- ness listings and supplying pet supply retailers with business cards and client education materials are also effective practice builders.

The term subclinical deficiency is often used to describe marginal nutrient deficiencies 500mg naprosyn free shipping. In many instances the only clue to a subclinical nutrient deficiency may be fatigue order naprosyn 500 mg line, lethargy, difficulty in concentration, a lack of well-being, or some other vague symptom. Worse, however, is that—as we extensively document in this book—chronic, long-term marginal deficiencies are an underlying cause of most of the disease we suffer in Western societies. Diagnosis of subclinical deficiencies is an extremely difficult process that involves detailed dietary or laboratory analysis. It’s not worth the cost to perform these tests because they are usually far more expensive than taking a year’s supply of the vitamin being tested for. These guidelines were originally developed to reduce the rates of severe nutritional deficiency diseases such as scurvy (deficiency of vitamin C), pellagra (deficiency of niacin), and beriberi (deficiency of vitamin B1). For example, even the Food and Nutrition Board acknowledges that smokers require at least twice as much vitamin C compared with nonsmokers. And what about the effects of alcohol consumption, food additives, heavy metals, carbon monoxide, and other chemicals associated with our modern society that are known to interfere with nutrient function? The Vitamin and Mineral Content of Conventionally Grown Foods Has Decreased Dramatically in the Past Century Even if you are conscientiously working to eat more whole foods, it is very difficult if not impossible to get all the required nutrients from food alone. A sad fact is that conventionally grown foods do not contain as high a concentration of nutrients today as they did in the past. For example, one study showed that vitamin levels have decreased by as much as 37% from 1950 to 1999,2 and another found that trace minerals have dropped by as much as 77% from 1940 to 1991. Eating more organically grown foods will help, but we see no alternative to smart supplementation. Conditionally Essential Nutrients In addition to essential nutrients, there are a number of food components and natural physiological agents discussed in this book that have demonstrated impressive health-promoting effects. These compounds exert significant therapeutic effects with little, if any, toxicity. More and more research indicates that these accessory nutrients, although not considered “essential” in the classical sense, play a major role in preventing illness as well as exerting specific therapeutic effects and promoting healthy aging. We refer to these compounds as “conditionally essential” to indicate that there are certain conditions where their use becomes essential in order for the body to function properly. Some Practical Recommendations There are four primary recommendations we make to people to help them design a foundation nutritional supplement program: 1. Recommendation 1: Take a High-Quality Multiple Vitamin and Mineral Supplement Taking a high-quality multiple vitamin and mineral supplement providing all of the known vitamins and minerals serves as a foundation upon which to build. Roger Williams, one of the premier biochemists of our time, states that healthy people should use multiple vitamin and mineral supplements as an “insurance formula” against possible deficiency. This does not mean that a deficiency will occur in the absence of the vitamin and mineral supplement, any more than not having fire insurance means that your house is going to burn down. But given the enormous potential for individual differences from person to person and the varied mechanisms of vitamin and mineral actions, supplementation with a multiple formula seems to make sense. The following recommendations provide an optimal intake range to guide you in selecting a high-quality multiple. For example, the recommended low-end dosage for vitamin B1 (thiamine) is 10 mg, so the daily dosage for children up to two years would be 10 mg × 0. For children two to four years old, the dosage is 40% of the low end of the range given; for children four to eight years old, the dosage is 60% of the low-end adult dosage; and for children nine years old or older the full adult dosage is sufficient. Elderly people living in nursing homes or at northern latitudes should supplement at the high range. It may be more cost-effective to take vitamin E separately rather than as a component of a multiple vitamin. Women who have or who are at risk of developing osteoporosis may need to take a separate calcium supplement to achieve the recommended level of 1,000 mg per day. Most women who have gone through menopause and most men rarely need supplemental iron. Potassium needs are best met through diet and the use of potassium salts used as salt substitutes. Read labels carefully to find multiple vitamin/mineral formulas that contain doses in these ranges. Be aware that you will not find a formula that provides all of these nutrients at these levels in one single pill—it would be too big. Usually you’ll need to take at least three to six tablets per day to meet these levels. While many once-daily supplements provide good levels of vitamins, they tend to be insufficient in the amount of some of the minerals they provide.

The forensic dentist will examine the suspected biting injury and con- sider the following: • Whether the injury is oval or round discount 500mg naprosyn with mastercard. However buy discount naprosyn 500 mg online, 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. The following have all been queried as biting injuries: • Dermatological conditions. In a single bite mark, one or any combination of several or all of these components may be present, and they may be discrete or superimposed. However, the complex situation may become even more complicated when there are multiple bite marks at a single location where they may overlap as a result of the biter trying to get a better “grip;” all this leads to interpretation difficulties. In attempting to get answers to these questions, a clearer picture of the incident may develop. Anatomical Distribution of Bitten Sites It can be seen from the anatomical distribution of the bite marks studied by the author (see Fig. This graph does not distinguish between male and female, child or adult, or whether there were multiple bites to one person, but serves purely to illustrate that it is essential for medical personnel to thoroughly examine the body for biting injuries and carefully document the findings. Record the anatomical location and nature of the injury and its size, shape, and color. In many cases, there are multiple bite marks on the body, some that the victim may not be aware of or recall. Mul- tiple bite marks on the body, produced by the same perpetrator, may vary Fig. Anatomical distribution of last 110 bite marks studied by the author (Hinchliffe). In short, do not jump to the conclusion that there are multiple biters or vice-versa. Nor should it be assumed that a small biting injury has been caused by a child; it may be an incomplete adult bite. If the marks on the skin can be identified as being made by the smaller deciduous (baby) teeth, it would suggest the mark has been inflicted by a young child. Evidence Collection As soon as it has been established that the injury has been caused by biting, the injury should be photographed and swabbed for saliva. In addition, it may be necessary to take an impression of the injured site to preserve any possible indentations. Clearly, the taking of forensic samples is not always possible when the injured party needs urgent medical attention. Often, the forensic dentist is provided with photographs taken some time after the inci- dent date and after medical intervention (see Fig. Saliva Saliva is deposited on the skin (and clothing, if present) during biting and sucking. The saliva swabs (with controls) must be clearly and correctly labeled and stored appropriately (see Chapter 3). Oral saliva samples will be needed from any potential suspect, and the victim of an assault if there is a possibility that the victim bit the assailant (or self-infliction is suspected). It is essential for correct photographic procedures to be followed to minimize dis- tortions. Police photographers experienced in crime scene and other injury pho- tography may still find the assistance of the forensic dentist useful, because Injury Assessment 155 Fig. Skin is not the best impression material, and various papers and reports have shown the importance of photographing the victim in the same position as when bitten in an attempt to minimize distortion (15,16). Changes in the injury with time (in both the living and the deceased) may mean that the injury pattern appears clearer after a day or two. There is no reliable way of knowing when an injury will reveal the most detail, and, therefore, repeat photography (e. Photograph Protocol • Anatomical location of bite mark (and identification of bitten person). Ultimately, the forensic dentist will select the best photographs and have them reproduced to life-size (1:1) for analysis and comparison work. At the time of writing, conventional film photography is still widely used, but the use of digital photography is progressing rapidly. Whatever the future brings, it is essential that standards, protocols, and appropriate training are in place. Dental Impressions Dental impressions taken from the potential biter by the dentist (or appropriately qualified person) after a thorough dental examination will be cast into hard dental models. Dental impressions taken of an individual in custody are intimate samples and require the appropriate authority and con- sent for your jurisdiction.

The standard interpretation of the social readjustment rating scale is that a total of 200 or more units in one year is considered to be predictive of a high likelihood of experiencing a serious disease generic 250 mg naprosyn amex. However 250 mg naprosyn for sale, rather than using the scale solely to predict the likelihood of serious disease, anyone can use it to determine his or her level of stressor exposure, because everyone reacts differently to stressful events. Salivary cortisol levels are reproducible, comparable to plasma levels, and easy to assess. Generally, an initially overactive acute stress response results in elevated cortisol levels, but chronic stress, insomnia, or depression may blunt this effect. Adrenal exhaustion is a common side effect of continual high stress as well as of steroid drugs such as prednisone, used in the treatment of allergic or inflammatory diseases. Therapeutic Considerations Whether you are aware of it or not, you have developed a pattern for coping with stress. Unfortunately, most people have found patterns and methods that ultimately do not support good health. Negative coping patterns must be identified and replaced with positive ways of coping. Try to identify any negative or destructive coping patterns listed below and replace those patterns with more positive measures for dealing with stress. Stress management can be substantially improved by focusing on the following six equally important areas: • Techniques to calm the mind, promote parasympathetic tone, and promote a positive mental attitude • Lifestyle factors • Exercise • A healthful diet designed to nourish the body and support physiological processes • Dietary and botanical supplements designed to support the body as a whole, but especially the adrenal glands • Supervised stress management program Negative Coping Patterns Dependence on chemicals: legal and illicit drugs, alcohol, smoking Overeating Too much television Emotional outbursts Feelings of helplessness Overspending Excessive behavior Calming the Mind and Body Learning to calm the mind and body is extremely important in relieving stress. The goal of relaxation techniques is to produce a physiological response known as a relaxation response—a response that is exactly opposite to the stress response that reflects activation of the parasympathetic nervous system. Although an individual may relax by simply sleeping, watching television, or reading a book, relaxation techniques are designed specifically to produce the relaxation response. The term relaxation response was coined by Harvard professor and cardiologist Herbert Benson in the early 1970s to describe a physiological response that he found in people who meditate. The parasympathetic nervous system controls bodily functions such as digestion, breathing, and heart rate during periods of rest, relaxation, visualization, meditation, and sleep. Although the sympathetic nervous system is designed to protect against immediate danger, the parasympathetic system is designed for repair, maintenance, and restoration of the body. Blood is shunted away from the skin and internal organs, except the heart and lung, while the amount of blood Blood is shunted toward internal organs, especially those supplying required oxygen and glucose to the muscles and organs involved in digestion. The rate of breathing rises to supply necessary oxygen to the The rate of breathing decreases as oxygen demand is reduced heart, brain, and exercising muscle. Sweat production increases to eliminate toxic compounds Sweat production diminishes, because a person who is calm produced by the body and to lower body temperature. Production of digestive secretions is severely reduced because Production of digestive secretions is increased, greatly digestive activity is not critical to counteracting stress. Blood sugar levels rise dramatically as the liver dumps stored Blood sugar levels are maintained in the normal physiological glucose into the bloodstream. It doesn’t matter which technique you choose, because all have the same physiological effect—a state of deep relaxation. The most popular techniques are meditation, prayer, progressive relaxation, self-hypnosis, and biofeedback. To produce the desired long-term health benefits, use the relaxation technique for at least 5 to 10 minutes each day. Breathing Producing deep relaxation with any technique requires learning how to breathe properly. One of the most powerful methods of producing less stress and more energy in the body is by breathing with the diaphragm. Diaphragmatic breathing activates the relaxation centers in the brain and the parasympathetic nervous system. Progressive Relaxation One of the most popular techniques for producing the relaxation response is progressive relaxation. The technique is based on a very simple procedure of comparing tension with relaxation. In progressive relaxation, an individual is taught what it feels like to relax by comparing relaxation with muscle tension. The basic technique is to contract a muscle forcefully for a period of one to two seconds and then give way to a feeling of relaxation in that muscle. The procedure systematically goes through all the muscles of the body, progressively producing a deep state of relaxation. The procedure begins with contracting the muscles of the face and neck, then the upper arms and chest, followed by the lower arms and hands. The process is repeated progressively down the body, from the abdomen through the buttocks, the thighs, and the calves to the feet. Progressive relaxation, deep breathing, or some other stress reduction technique is an important component of a comprehensive stress management program. Lifestyle A person’s lifestyle is a major determinant of his or her stress levels.
