The value of constitutional description as a factor linking clinical descriptions from different sources is illustrated in various works purchase skelaxin 400 mg overnight delivery. In a series of 200 cases buy skelaxin 400 mg with mastercard, a particular physique was identified discount 400mg skelaxin visa, characterized by asthenic habitus, thin and dry skin, scanty perspiration, sparse body hair, cervical lymphadenitis, postural hypotension, and cold extremities. Such patients tended to exhibit a positive Rogoff sign (tenderness in the vertebrocostal angle), and on laboratory investigation, to show low urinary 17-ketosteroid levels, eosinophilia, and a flat glucose tolerance test result. Patients in this series tended to experience fatigue, anxiety, depression, faintness, insomnia, allergies, dermatoses, and a variety of symptoms related to autonomic imbalance. Tintera believed that these individuals were particularly prone to “adre- nal exhaustion” under stress and that therapy should aim at resting and sup- porting the adrenal glands and stabilizing blood sugar levels. Consequently, he recommended a high-protein, low–refined-carbohydrate diet with sup- plements of vitamins B and C. He placed particular emphasis on vitamins B6 28 Part One / Principles of Nutritional Medicine and B12. A crucial part of the therapy, however, was the administration of intravenous or intramuscular adrenocortical extract over variable periods to “rest” the adrenal glands. In contrast, Bieler’s9 main distinction lay between individuals who had either a dominant thyroid gland or a dominant adrenal gland. The “thyroid type” was described as slender, fine-boned, and long-limbed; and the “adre- nal type” closely resembled Sheldon’s mesomorph. Table 2-1 outlines a num- ber of key features of the Bieler thyroid type and compares it with Tintera’s description of the hypoadrenal type, Sheldon’s description of the ecto- morph, and the traditional Ayurvedic Vata type. Each approach adds valuable information that can be used in understanding etiology and in implementing appropriate treatment. The connecting thread is the description of the physical reality of the constitutional type. Sheldon was particularly interested in the connection between physical constitution and temperament, although he did not hold any simplistic view as to the relationship between the two. He saw person- ality as a product of “the play of a complex pattern of environmental pres- sures upon a living organism that carries an innately determined constitutional patterning. The viscerotonic individual is described as a relaxed, comfortable person who participates easily in social gatherings and who shows a warm interest in and tolerance of the human race. The person with a somatotonic temperament is extremely active and energetic with a tendency to self-assertion and even aggression. The extreme cerebrotonic individual is an introvert and thus under strong inhibitory control with regard to feelings and socialization. Although subsequent research has shown that there is an element of con- stitutional or predictable behavior associated with particular somatotypes, the majority of investigative efforts have been confused by the variety of somatotyping methods and the problems inherent in psychologic invento- ries. Most of the psychologic tools used for assessing personality and behav- ior fail to distinguish between temperament (inherited) and character (acquired traits). The most significant correlations will obviously arise only between somatotype and temperament variables. Cloninger’s Themperament and Character Inventory seems to offer a way out of the confusion. In contrast, alternative models, measured by such tools as the Eysenck Personality Questionnaire, are genetically heterogeneous. We can expect that research that examines correlations between somatotype and these four temperament variables might show definite relationships, and in fact, it is tempting to speculate with Arraj12 that there would be correlations between harm avoid- ance and ectomorphy, novelty seeking and mesomorphy, and reward depend- ence and endomorphy. My own clinical observations leave me in no doubt that there is a significant correlation between ectomorphy and harm avoid- ance and that this combination of characteristics predisposes the ectomor- phic group to a higher incidence of anxiety and chronic fatigue syndrome. However, research in this area is complicated by the fact that there are only poor correlations between the somatotype of the child and the adult. Tracking these chil- dren into adult life will provide some clues about the complex interactions of somatotype, temperament, and character. At the biochemical level, the enormous complexity of cellular activity makes individuality more difficult to charac- terize. Roger Williams, way ahead of his time, demonstrated a wide varia- tion in animal nutrient requirement and showed that human differences in biochemical parameters were much greater than differences in physical appearance. However, we should not underestimate the challenges that will arise in interpreting the vast complexity so revealed, and more will be said on this point in the following section on models of health and disease. Collins, Director of the National Human Genome Research Institute in the United States, has contextualized the likely changes that will come in the wake of this technology by making the following predictions. The family tree may be especially useful in determining which foods are likely causes of Chapter 2 / The Art of Nutritional Medicine: Patient-Centered Care 31 disease. Thus grain or milk sensitivity may be suggested by information from the following areas: ● Diagnosed illnesses such as celiac disease, cancer of the bowel, or autoimmune syndromes such as systemic lupus erythematosus ● Recurrent undiagnosed symptoms such as chronic gastrointestinal problems, tiredness, headaches, or depression The secret of this approach is to be very familiar with the protean manifes- tations of food and environmental sensitivities and to recognize patterns as they recur through generations. For example, the index of suspicion for gluten sensitivity in an autistic child would be raised if the mother was expe- riencing irritable bowel syndrome and a grandparent had been given diag- noses of systemic lupus erythematosus and depression. While the exciting prospects offered by genetic research play themselves out in the many and diverse fields of biology and medicine, we are left with the task of making clinically useful decisions about individual biochemical differences and needs. Measures of nutrient status provide some help but are accompanied by the many problems outlined in Chapter 6. This and other factors have led to the search for a metabolic typology that would guide dietary nutrient prescription. Attempts at metabolic typing have not been overwhelmingly successful, although the approaches of two pioneers, George Watson and William Donald Kelley, deserve consideration from both historical and clinical points of view. Watson18 found that nutrients had differential effects on individuals, especially with respect to psychologic state, and he developed a theory based on cellular oxidation to explain his findings. In this scheme there are two basic metabolic types—fast oxidizers and slow oxidizers. Fast oxidizers show a disproportionately fast oxidation of carbohydrates and glucogenic amino acids together with slow but still more rapid than normal oxidation of fats and ketogenic amino acids. Such individuals will tend to have higher blood carbon dioxide levels and lower pH values. In contrast, slow oxidiz- ers show a slow oxidation of carbohydrates and glucogenic amino acids with a slow but preferential utilization of fats and ketogenic amino acids. Such individuals will tend to have lower carbon dioxide levels in a generally more alkaline biochemical environment. The aim of therapy is to provide macronutrients and micronutrients that will assist the more inefficient aspects of metabolism. Thus the slow oxidizer needs to consume less fat and more complex carbohydrates, together with cofactors that would assist in carbohydrate metabolism. The opposite is true of the fast oxidizer who needs to rely less on carbohydrates and more on the metabolic effects of pro- tein and fat. A detailed discussion of this process is beyond the scope of this chapter, but Table 2-2 provides an overall summary of the strategies. Watson did not provide us with any descriptive correlations between his concept of meta- bolic type and somatotype.

Each static stretch should be held at least ten seconds order skelaxin once a day, working up to 20 to 30 seconds buy skelaxin paypal, and usually repeated three to four times purchase skelaxin 400mg fast delivery. Keep your back aligned, your abdominal muscles contracted, buttocks tucked in, and knees aligned over the feet. When you are starting a new program, have someone else watch you to make sure your position is correct throughout your workout. These call for gradual stretching throughout a muscle’s full range of movement until you feel resistance. Wearing improper or worn-out shoes places added stress on your hips, knees, ankles, and feet, where up to 90 percent of all sports injuries occur. Aerobics instructors suffer injuries to their bodies because of the repetitive, jarring movements of some routines. Substitute the marching or gliding movements of low-impact aerobics for the jolting up-and-down motion of typical aerobics routines. Slowly jog for five minutes, even in place if need be, before your workout to gradually increase your heart rate, and core and muscle temperatures. This is particularly important in hot weather, when you can easily lose more than a quart of water in an hour. Even after you have a well-established exercise program, there will be interruptions. You may be ill, you may be in a setting where it is difficult to exercise, shipboard duties may take precedence over leisure activities, or you may sustain an injury. The general rule is that it will take as long to get back to your previous level of activity as you were out. If you cannot exercise for two weeks, gradually increase your activity over a two-week period to get back to your previous level. After your exercise program is established, make sure that it becomes a habit you want to continue for a long time. In 1980 the United States Department of Agriculture and the United States Department of Health and Human Services first issued Nutrition and Your Health: Dietary Guidelines for Americans to provide practical dietary advice based on current research. In addition, the Dietary Guidelines Advisory Committee was established to incorporate new scientific data, and to update the guidelines. The latest revision of the Dietary Guidelines for Americans provides the basis for all Federal nutrition information and education programs for healthy Americans. They are for healthy people two years of age and over, and are not for people who need special diets because of disease and conditions that interfere with normal nutrition. Generally, these guidelines can be followed for a short period of time by people with chronic diseases until more specific advice can be 6-6 obtained from a Registered Dietitian. If one occasionally eats foods that are higher in fat, sugars, or sodium, balance them during the day with other foods that are lower. These Guidelines offer tips for helping to choose foods for a healthful diet: Eat a variety of foods. The nutrients should come from a variety of foods, not from a few highly fortified foods or supplements. A varied diet is defined below by the Food Guide Pyramid with suggested numbers of servings from vegetables, fruits, grain products, dairy products and meat/meat substitutes. A "healthy" body weight depends on the percentage of body weight as fat, the location of fat deposition, and the existence of any weight-related medical problems. However, using tables with suggested weight-for-height-and-age is a popular method of estimating recommended body weight. A number of studies suggest a possible association between excess body weight and several cancers including breast, uterine, colon, gallbladder, and prostate. Of all the dietary factors thought to affect cancer, fat has been the subject of the most research. Substantial evidence suggests that excessive fat intake increases the risk of developing cancers of the breast, colon, and prostate. The National Cancer Institute and National Cholesterol Education Program recommend reducing total fat intake to 30% or less of total calorie intake. This level of fat intake can be achieved by a change in eating habits and is also an effective way to reduce total calories. Consuming more vegetables, fruits, breads, cereals, potatoes, pasta, rice, and dry beans and peas are emphasized especially for their complex carbohydrates, dietary fiber, and other components linked to good health. Some of the benefits from a high fiber diet may be from the food that provides the fiber, not from fiber alone, so fiber from foods is recommended over fiber obtained from supplements. Limit all sugars table sugar, brown sugar, corn sweeteners, syrups, honey, and molasses. Limit the foods high in sugars, such as prepared baked goods, candies, sweet desserts, soft drinks, and fruit-flavored punches. Eat fresh fruits, unsweetened frozen fruits, or canned fruits packed in water, juice, or light syrup. Limit use of high-sodium condiments (soy sauce, steak sauce, catsup), pickles and relishes, and salty snacks. Use only moderate amounts of cured or processed meats, most canned vegetables and soups. A reduction in salt (and sodium) intake will benefit those people whose blood pressure rises with salt intake. Drinking alcoholic beverages has few, if any, net health benefits and is linked to many health problems and accidents. Therefore, individuals who drink alcoholic beverages are advised to use moderation. Moderate drinking is defined as no more than one drink per day for women and two drinks per day for men. Heavy drinkers are at increased risk for various cancers such as oral cavity, larynx, and esophagus. Pregnant women should completely avoid alcoholic beverages throughout their pregnancy. Coordination and judgment are reduced by alcohol; this can lead to serious falls and on-the-job injuries. Limit caffeinated beverages, alcohol, and other diuretics; however, some data indicate that drinking tea, especially green tea, may have health benefits due to antioxidant properties. A dietary supplement is any product intended for ingestion as a supplement to food intake. Such supplements are vitamins, minerals, herbs, botanicals and other plant-derived substances, amino acids, food concentrates and extracts. For anyone who eats a reasonably balanced diet that emphasizes fruits and vegetables, developing a vitamin deficiency is unlikely. The minerals needed in a healthy diet are mostly metals and salts, such as iron, phosphorus, and calcium.

It is a precursor for acetylcholine, phospholipid (lecithin), sphin- gomyelin, platelet-activating factor, and the methyl donor betaine. Lecithins added during food processing may increase the average intake of phosphatidylcholine by 1. At a dose of 10 g/day, cholin- ergic side effects include diarrhea, dizziness, sweating, and electrocardio- graphic changes. In its trivalent state, chromium is an essential trace element required for carbohydrate, lipid, and nucleic acid metabolism. Contrary to popular belief, chromium has not been shown to increase muscle mass or decrease body fat. Chromium increases insulin binding to cells and insulin receptor num- bers and activates insulin receptor kinase, leading to increased insulin sensi- tivity. Glucose tolerance factor is composed of trivalent chromium, two nicotinic acid molecules, and a small oligopeptide. The chromium-binding oligopep- tide chromodulin is thought to play a unique role in the auto-amplification of insulin signaling. Barley is a good source of chromium and should be included in the diet of patients with diabetes. Although higher intakes are more effective, 200 μg of supplemental chromium daily is adequate to improve glucose levels in individuals with mild glucose intolerance. In gestational diabetes, chromium in doses of 8 μg/kg body weight is more effective than 4 μg/kg,6 and steroid-induced diabetes can be reversed by chromium supplementation in doses of 600 μg daily. Results of a recent double-blind, crossover trial confirmed that chromium supplementa- tion improved control of glucose and lipid levels while decreasing drug dosage in patients with type 2 diabetes. Preliminary observations suggest that chromium, 200 μg once or twice daily, may enhance antidepressant therapy for dysthymic disorder, with symptomatic improvement occurring within 3 days of treatment. Although chromium has been touted as an agent for increasing lean body mass and decreasing body fat,10 chromium supplementation does not appear to promote muscle accretion or fat loss or to enhance strength in young men and women. Supplementation with chromium picolinate, but not chromium chloride, decreases transferrin saturation. The bioavailability of chromium is better in oral chromium picol- inate or nicotinate salt supplements. Chromium supplementation is likely to alter the amount of insulin required by patients with diabetes and a chromium deficiency. Chromium may reduce insulin requirements and enhance the effects of oral hypo- glycemic agents. Furthermore, suboptimal dietary intake of chromium appears to be associated with risk factors for diabetes and cardiovascular diseases, such as impaired glucose tolerance, increased circulating insulin levels, glucosuria, and hyperlipidemia. Studies also suggest that even the lowest normal chromium intake (25%) has a detrimental effect on glucose tolerance and insulin and glucagon levels in subjects with mildly impaired glucose tolerance. Patients with type 2 diabetes lose more chromium in their urine than individuals without diabetes, and diets low in chromium may have adverse effects on patients with borderline diabetes.

Coenzyme Q10 is a vital cell membrane antioxidant and facilitates cellular respiration. Coenzyme Q10 is often included in anti-aging potions in view of its role in energy generation and the finding that cellular levels decrease with age. As an electron and proton carrier, it is essential for production of adenosine triphosphate in the electron transport chain. In addition to its role in energy production, coenzyme Q10 is thought to have membrane-stabilizing proper- ties. Rich dietary sources are fatty fish such as sardines and beans, nuts, whole grains, and meat. Some patients do lose their appetite and have skin eruptions during supplementation with coenzyme Q10. A synthetic analogue of coenzyme Q10, idebenone [2,3-dimethoxy- 5-methyl-6-(10-hydroxydecyl)-1,4-benzoquinone], is available. It may improve immune function, preventing metastasis and enhancing remission in certain cancers; reduce the risk of obesity; enhance myocardial contractility; reduce male infertility; protect gastric mucosa as a result of its antioxidant effects; and improve blood sugar control in patients with diabetes. However, clinical trials in which coen- zyme Q10 (100-200 mg daily) was used for the management of congestive heart failure have had conflicting results. Coenzyme Q10 is also of interest with respect to energy production in patients with chronic fatigue syndrome. Patients with chronic fatigue syn- drome are often deficient in coenzyme Q10, and in one study, supplementa- tion with 100 mg daily over 3 months improved exercise tolerance and reduced clinical symptoms. Two potential dietary means of delaying the effects of free radicals on cellular aging are enrichment of mitochondrial membranes with monounsaturated fatty acids and supplementation with antioxidants. A preliminary study of elderly male rats suggests that dietary supplementation with coenzyme Q10 and enrichment of cell membranes with monounsaturated fatty acids protect mitochondrial membranes from free radical insult. Antihypertensive agents—such as the β-blockers propranolol and metoprolol, pheno- Chapter 59 / Coenzyme Q10 (ubiquinone) 495 thiazines, and tricyclic antidepressants—inhibit coenzyme Q10–dependent enzymes.

The total body content of copper is pri- marily regulated by means of excretion rather than absorption. Copper is excreted attached to taurochenodeoxycholic acid, a sulfur-containing bile acid that is stored in the liver. When mobi- lized, copper is found in the plasma firmly attached to protein as cerulo- plasmin. Copper (Cu) plays a role in hemoglobin synthesis, neural function, glu- cose utilization, and skeletal and cardiovascular health. Copper salicylate is known to have analgesic and anti-inflamma- tory effects, and the efficacy of various copper-based anti-inflammatory drugs is under investigation. Its effi- cacy is often mediated by oxidation-reduction reactions in which Cu+ is con- verted to Cu2+.

Importantly purchase skelaxin paypal, these neurochemical and behavioural effects of pro- biotic treatment are prevented by bilateral subdiaphragmatic vagotomy. Theoreti- cally, neuropeptide-like molecules may also be produced by certain microbes, and the gut microbiota will respond to neuropeptides and gut hormones if it expresses the relevant receptors. However, direct evidence that these neuropeptides contrib- ute to the communication between the gut microbial community and the central nervous system is sparse. It also remains to be investigated whether alterations in the microbial community within the gut impacts on neuropeptide systems in the central nervous system. Farzi The information available is mostly restricted to peptide level changes associ- ated with manipulation of the intestinal microbiota. For instance, the colonic content of substance P is enhanced following antibiotic-induced dysbiosis of the intestinal microbiota [65]. On the one hand, the establishment of inflammatory hyperalgesia is attenuated in germ- free mice [66]. On the other hand, treatment of rodents with the probiotic Lacto- bacillus reuteri attenuates sensory neuron excitability [67] and alleviates the pain- related response to gastric distension [68]. Lactobacillus acidophilus also reduces experimentally evoked visceral pain, an effect that is associated with enhanced expression of opioid and cannabinoid receptors in the intestinal mucosa [69]. Neuropeptide Autoantibodies Under the Control of the Intestinal Microbiota The gut microbiota is important in educating the immune system to recognize foreign antigens and to tolerate commensal microbes [71]. In this way, the gut microbes can modulate, tune and tame the host immune response [72]. Dysbiosis of the microbial community can lead to the development of autoimmunity [72, 73], and experimental findings indicate that both autoimmune encephalomyelitis [74] and autoimmune demyelination [75] involve the gut microbiota. There is also evidence that the formation of autoantibodies against neuropeptides is governed by intestinal microbes [76–78]. Numerous intestinal microbes including Lactobacillus, Bacteroides, Helicobacter pylori, Escherichia coli and Candida species contain proteins that have amino acid sequences identical to these appetite-regulating peptides [78]. The circulating levels of autoantibodies against alpha-melanocyte-stimulating hormone, which are increased in anorexia nervosa and bulimia nervosa, correlate with the psychobehavioural abnormalities of these eating disorders [76]. Vice versa, germ- free rats have decreased levels of circulating IgA autoantibodies against several appetite-regulating peptides, while the levels of antighrelin IgG are increased [78]. A mechanistic analysis in rats has shown that alpha-melanocyte-stimulating hormone autoantibodies are involved in the regulation of feeding and anxiety [78]. It thus appears conceivable that the gut microbiota control appetite and 9 Neuropeptides and the Microbiota-Gut-Brain Axis 205 emotional behaviour indirectly by inciting the formation of autoantibodies against neuropeptides/peptides involved in these processes. This contention is based on this neuropeptide’s involvement in controlling inflammatory processes, pain, emotion, mood, cognition, stress resilience, ingestion and energy homeostasis [6]. Y receptors occur at all levels of the gut-brain and brain-gut axis [6, 80–84], the major systems expressing this peptide being enteric neurons, primary afferent neurons, several neuronal pathways throughout the brain and sympathetic neurons (Fig. It may • influence the vitality of certain gut bacteria, • modify gut functions such as motility, secretion and blood flow, • regulate the activity of the immune system, • protect against behavioural disturbances caused by peripheral immune challenge, • inhibit nociceptive transmission in the spinal cord and brainstem, • protect from the impact of stress on the brain-gut axis, • regulate food intake and energy homeostasis, and • play a role in the interoceptive regulation of anxiety and mood. The signalling pathways whereby peripheral immune challenge alters brain mechanisms involve proinflammatory cytokines such as interleukin-6, tumour necrosis factor-alpha and interferon-gamma, which reach the brain via the circulation but also excite vagal afferent neurons and lead to the expression of cytokines by cerebral microglial cells and astrocytes [18, 19, 106–108]. Peripheral inflammation leads to an upregulation of Y1 receptors in spinal afferent neurons and in the dorsal horn of the spinal cord [117]. Since stress can alter the permeability of the gastrointestinal mucosa [126, 127], it is very likely that stress will also alter the interaction between the gut microbiota and the mucosal immune system. These roles have been extensively reviewed elsewhere [10, 132, 133] and may be of particular relevance to the impact of the gut microbiota on metabolic regulation, energy homeostasis and metabolic disorders. In an evolutionary point of view, co-regulation of appetite and emotional state is an important strategy for survival, given that anxiety would be an adverse condition when there is a need to seek food [6]. Indeed, ghrelin which is released from the upper gastrointestinal tract under conditions of hunger reduces both anxiety-like and depression-related behaviour [138]. Gut hormones whose release from the enteroendocrine cells is likely to be regulated by the gut microbiota thus provide a constant stream of interoceptive input from the gut to the brain. Conclusion: The Gut Microbiota Meets Neuropeptides The gut microbiota has proved as a novel factor relevant to health and disease. How the gut microbiota communicates with distant organs such as the brain is only beginning to emerge. It is very probable that the microbiota will take use of several information carriers from the gut to the brain including microbiota-derived signal- ling molecules, immune mediators, gut hormones as well as vagal and spinal afferent neurons. Biologically active gut peptides and neuropeptides play a role in several of these communication pathways. This is true for peptides produced by enteroendocrine cells which respond to metabolites generated with the help of the microbiota. Neuropeptides are important transmitters in afferent, central and efferent pathways of the bidirectional gut-brain communi- cation network. It remains to be shown whether the gut microbiota itself expresses neuropeptide receptors or releases metabolites that are ligands at neuropeptide receptors.

Wiped onto a cloth or article of clothing, this theatrical blood looks very realistic. Consider renting one of these movies and repeatedly watching only the injec- tion scenes until your anxiety lessens. Your pharmacy or local diabetes clinic may have educational videos avail- able to teach people how to give insulin injections. You may also want to consider movies or videos that involve subjects like tattooing, piercing, or acupuncture. You may be able to receive immunizations for various infections such as hepatitis A or B. Your doctor may be able to supply you 68 overcoming medical phobias with a few needles that you could take home and use as exposure items. Go along and watch when your helper or a friend visits the doctor for a vaccination or a flu shot. Or, go along and watch when your helper or a friend has blood taken or gets a piercing. If you know someone who has a condition that requires regular injections (such as insulin for diabetes), ask if you could watch the injection process. You may find that once treatment is under way, some items you initially thought would be helpful become less so. You may also find the opposite is true—as you progress with your exposure exercises, you discover new ideas, situ- ations, or objects that cause fear. Because tracking down items, images, and settings for your exposure practice will require you to encounter things and situations that may cause you great distress, you should consider having your helper preparing for treatment 69 assist in this process. You should go over your hierarchy and your list of needed items with your helper and discuss who will get what, leaving some of the more anxiety- provoking items for your helper to screen ahead of time. This is why it’s important to have a helper who doesn’t have the same fear you do. In fact, reading through this chapter may have been a bit of an exposure exercise in itself. Remem- ber, too, that often these exercises can leave you feeling drained, tired, tearful, or irritable. Some people find they feel more tense afterward and have to deal with head- aches or muscle stiffness. To help cope with these poten- tial reactions, plan to reward yourself after each exposure exercise. Make a point of going for a walk, getting together with friends, listening to some of your favorite music, or soaking in a warm bath. Consider buying your- selfatreat,suchasanewoutfitordinneratagreatres- taurant, to reward yourself for a job well done after tackling a really tough step on your hierarchy. In this chapter, we discussed the potential benefits of enlisting a helper, who may be a friend, a family member, or a professional therapist. We also reviewed the importance of gathering materials to use in your exposure practices and suggested a number of resources available to that end. Following the guidelines and suggestions in this chapter will help you lay the foun- dation for successful treatment. The drive to be comfortable leads people to take medication for a headache, run cold water over a burn, eat when hungry, sleep when tired, or have a glass of wine when feeling shy at a party. Therefore, one of the most noticeable fea- tures of any phobia is the tendency to avoid feared situa- tions or to find ways of protecting oneself from feeling overly anxious or frightened in these situations. For example, although many sleep medi- cations are effective for improving sleep on any particular night, discontinuing these medications after a period of regular use is often associated with “rebound” insomnia caused by withdrawal from the medication. In other words, these medications offer a short-term solution to insomnia that may actually increase the problem in the future, when the person stops taking the medication. In the same way, avoiding or escaping from a feared situation leads to immediate relief but makes it more likely that you’ll continue to have fear when you encounter the situa- tion in the future. As we discuss in chapter 7, fear and anxiety are often triggered by negative predictions and assumptions that a situation is dangerous in some way. Examples of such predictions include beliefs that you will faint, that a needle will be painful, that you will be overwhelmed with feelings of fear or disgust, or that a dentist will hurt you. In fact, any prediction of danger or threat can lead to feelings of anxiety or fear. By avoiding a feared situation, you never have a chance to find out whether your predic- tion is in fact true, whether the outcome is as bad as you expected it to be, and whether you are able to cope with the situation. Just as avoiding dogs almost guarantees that someone won’t overcome a fear of dogs, avoiding blood, needles, doctors, or dentists will ensure that your fear is confronting your fear 73 maintained over time. Only through repeated exposure to the situation will you start to experience some long-term relief from your fear. If you can’t think of a fear you overcame, try to think of a fear that someone close to you overcame in the past. Chances are that the fear was overcome through confronting the situation until it became easier. Though exposure is one of the most powerful ways to overcome almost any fear, the process isn’t easy. If you have a history of passing out upon expo- sure to blood, injections, and related situations, there is a risk of fainting during your exposure practices. Also, chapter 6 is devoted to the topic of preventing fainting during exposure prac- tices. Many people have a great sense of satisfaction and even excitement following each practice, especially when they start to notice their 74 overcoming medical phobias fear decreasing as a result of exposure. A sense of free- dom may also emerge as you begin to realize that situa- tions that were previously off-limits are now a possibility. For most people, the temporary increase in discomfort is manageable, and it’s almost always well worth it. It’s only after a few weeks of regular exercise that you start to notice the benefits, including more energy, increased strength, weight loss, and a decreased risk of various illnesses. If you can tolerate some initial discomfort, you’ll quickly start to see the benefits—including a reduction in fear and anxiety and an increase in the range of things that you can do comfortably. In fact, more than half the peo- ple who have these phobias have a history of fainting in the feared situation. However, if you do have a history of fainting, we have a few additional recommendations: Make sure you read chapter 6 before trying the exposure practices described in this chapter. Although exposure alone is an effective treatment for fears of blood, needles, doctors, and dentists, combining the exposure strategies with the muscle tension exercises described in chapter 6 will help to prevent fainting during your practices. For most people, fainting on occasion in a controlled situation is perfectly safe.

Dust: small infectious particles of widely varying size that may arise from soil best buy skelaxin, clothes buy discount skelaxin 400 mg on-line, bedding or contaminated floors and be resuspended by air currents skelaxin 400mg with mastercard. Droplet nuclei : Small residues resulting from evaporation of fluid (droplets emitted by an infected host). Portal of entry: The site in which the infectious agent enters to the susceptible host. Susceptible host (host factors): A person or animal lacking sufficient resistance to a particular pathogenic agent to prevent disease if or when exposed. The term “immunity” is used to describe the ability of the host to resist infection. Resistance to infection is determined by non-specific and specific factors: Non-specific factors Skin and mucus membrane Mucus, tears, gastric secretion Reflex responses such as coughing and sneezing. Specific factors Genetic-hemoglobin resistant to Plasmodium falciparum Naturally acquired or artificially induced immunity. Healthy or asymptomatic carriers: These are persons whose infection remains unapparent. For example, in poliovirus, meningococcus and hepatitis virus infections, there is a high carrier rate. Incubatory or precocious carriers: These are individuals or persons who excrete the pathogen during the incubation period (i. Convalescent Carriers: These are those who continue to harbor the infective agent after recovering from the illness. For example, in a measles patient, fever and coryza occur in the first three days and Koplick spots in the buccal mucosa and characteristics skin lesions appear on the fourth day. Period of communicability: The period during which that particular communicable disease (infectious agent) is transmitted from the infected person to the susceptible host. Primary prevention: The objectives here are to promote health, prevent exposure, and prevent disease. Health promotion: This consists of general non-specific interventions that enhance health and the body’s ability to resist disease, such as measures aimed at the improvement of socio-economic status through the provision of adequately- paid jobs, education and vocational training, affordable and adequate housing, clothing, and food, old-age pension benefits; emotional and social support, relief of stress, etc. In 16 Communicable Disease Control short it is any intervention that promotes a healthier and happier life. Prevention of exposure:- This includes actions such as the provision of safe and adequate water, proper excreta disposal, vector control, safe environment at home (e. Prevention of disease:-This occurs during the latency period between exposure and the biological onset of disease. Immunization against an infectious organism does not prevent it from invading the immunized host, but prevents it from establishing an infection. Active immunization means exposing the host to a specific antigen against which it will manufacture its own protective antibodies after an interval of about three weeks (during which the immunized person remains susceptible to the disease). Passive immunization means providing the host with the antibodies necessary to fight against disease. However, for active immunization to be protective, the timing of its administration must be at least three weeks prior to exposure. Passive immunization, on the other hand, 17 Communicable Disease Control is commonly given after exposure has occurred (as in the case of exposure to rabies or tetanus), or shortly before an exposure is expected, as in the administration of immune globulin to prevent viral hepatitis A). Breastfeeding is an example of an intervention that acts at all three levels of primary prevention: Health promotion: by providing optimal nutrition for a young child, either as the sole diet up to four months of age, or as a supplement in later months. Secondary prevention: After the biological onset of disease, but before permanent damage sets in, we speak of secondary prevention. The objective here is to stop or slow the progression of disease so as to prevent or limit permanent damage, through the early detection and treatment of disease. Thertiary prevention: After permanent damage has set in, the objective of tertiary prevention is to limit the impact of that damage. The impact can be physical, psychological, social (social stigma or avoidance by others), and financial. Rehabilitation refers to the retraining of remaining functions for maximum effectiveness, and should be seen in a very broad sense, not simply limited to the physical aspect. Thus the provision of special disability pensions would be a form of tertiary prevention. Methods of Communicable Disease Control There are three main methods of controlling communicable diseases: 1. Man as reservoir: When man is the reservoir, eradication of an infected host is not a viable option. Instead, the following options are considered: 19 Communicable Disease Control Detection and adequate treatment of cases: arrests the communicability of the disease (e. Isolation is indicated for infectious disease with the following features: - High morbidity and mortality - High infectivity Quarantine: limitation of the movement of apparently well person or animal who has been exposed to the infectious disease for a duration of the maximum incubation period of the disease. Animals as reservoir: Action will be determined by the usefulness of the animals, how intimately they are associated to man and the feasibility of protecting susceptible animals. For example: Plague: The rat is regarded as a pest and the objective would be to destroy the rat and exclude it from human habitation. Reservoir in non-living things: Possible to limit man’s exposure to the affected area (e. Interruption of transmission This involves the control of the modes of transmission from the reservoir to the potential new host through: Improvement of environmental sanitation and personal hygiene Control of vectors Disinfections and sterilization 3. Protection of susceptible host: This can be achieved through: Immunization: Active or Passive Chemo-prophylaxis- (e. State the six important factors that involve the chain of communicable diseases transmission. Oral-oral transmission occurs mostly through unapparent fecal contamination of food, water and hands. As indicated in the schematic diagram below, food takes a central position; it can be directly or indirectly contaminated via polluted water, dirty hands, contaminated soil, or flies. Infectious agent Salmonella typhi Salmonella enteritidis (rare cause) Epidemiology Occurrence- It occurs worldwide, particularly in poor socio- economic areas. Annual incidence is estimated at about 17 million cases with approximately 600,000 deaths worldwide. In endemic areas the disease is most common in preschool and school aged children (5-19 years of age). Reservoir- Humans Mode of transmission- By water and food contaminated by feces and urine of patients and carriers. Flies may infect foods in which the organisms then multiply to achieve an infective dose. Incubation period –1-3 weeks 25 Communicable Disease Control Period of communicability- As long as the bacilli appear in excreta, usually from the first week throughout convalescence. About 10% of untreated patients will discharge bacilli for 3 months after onset of symptoms, and 2%-5% become chronic carriers. Relative specific immunity follows recovery from clinical disease, unapparent infection and active immunization but inadequate to protect against subsequent ingestion of large numbers of organisms. Clinical manifestation First week- Mild illness characterized by fever rising stepwise (ladder type), anorexia, lethargy, malaise and general aches. Severe illness with weakness, mental dullness or delirium, abdominal discomfort and distension.
