What distinguishes an optimist from a pessimist is the way in which they explain both good and bad events. Martin Seligman has developed a simple test to determine your level of optimism (see Learned Optimism, Knopf, 1981). Your boss gives you too little time in which to finish a project, but you get it finished anyway. In other words, the results will tell you about the way in which you explain things to yourself. There are three crucial dimensions to your explanatory style: permanence, pervasiveness, and personalization. When pessimists are faced with challenges or bad events, they view the events as being permanent. In contrast, people who are optimists tend to view the challenges or bad events as temporary. Each one with a “0” after it is optimistic; each one followed by a “1” is pessimistic. Total the numbers at the right-hand margin of the questions coded PmB, and write the total on the PmB line on the scoring key. If you totaled 0 or 1, you are very optimistic on this dimension; 2 or 3 is a moderately optimistic score; 4 is average; 5 or 6 is quite pessimistic; and 7 or 8 is extremely pessimistic. Now let’s take a look at the difference in explanatory style between pessimists and optimists when there is a positive event in their lives. Pessimists view positive events as temporary, while optimists view them as permanent. If you totaled 7 or 8, you are very optimistic on this dimension; 6 is a moderately optimistic score; 4 or 5 is average; 3 is pessimistic; and 0, 1, or 2 is extremely pessimistic. If you are scoring as a pessimist, you may want to learn how to be more optimistic. Your anxiety may be due to your belief that bad things are always going to happen, while good things are only a fluke. Pervasiveness refers to the tendency to describe things in universals (everyone, always, never, etc. Pessimists tend to describe things in universals, while optimists describe things in specifics. If you totaled 0 or 1, you are very optimistic on this dimension; 2 or 3 is a moderately optimistic score; 4 is average; 5 or 6 is quite pessimistic; and 7 or 8 is extremely pessimistic. Optimists tend to view good events as universal, while pessimists view them as specific. Total your score for the questions coded PvG (for Pervasive Good): 6, 7, 28, 31, 34, 35, 37, and 43. If you totaled 7 or 8, you are very optimistic on this dimension; 6 is a moderately optimistic score; 4 or 5 is average; 3 is pessimistic; and 0, 1, or 2 is extremely pessimistic. Our level of hope or hopelessness is determined by our combined level of permanence and pervasiveness. If it is 0, 1, or 2, you are extraordinarily hopeful; 3, 4, 5, or 6 is a moderately hopeful score; 7 or 8 is average; 9, 10, or 11 is moderately hopeless; and 12, 13, 14, 15, or 16 is severely hopeless. People who make permanent and universal explanations for their troubles tend to suffer from stress, anxiety, and depression; they tend to collapse when things go wrong. When bad things happen, either we can blame ourselves (internalize) and lower our self-esteem as a consequence, or we can blame things beyond our control (externalize). Although it may not be right to deny personal responsibility, people who tend to externalize blame in relation to bad events have higher self- esteem and are more optimistic. Total your score for the questions coded PsB (for Personalization Bad): 3, 9, 16, 19, 25, 30, 39, 41, and 47. A score of 0 or 1 indicates very high self-esteem and optimism; 2 or 3 indicates moderate self- esteem; 4 is average; 5 or 6 indicates moderately low self-esteem; and 7 or 8 indicates very low self- esteem. When good things happen, the person with high self-esteem internalizes while the person with low self-esteem externalizes.

The data indicated that niacinamide improved C-peptide release and blood glucose control in type 2 diabetic patients who had previously failed to respond to oral diabetes drugs alone buy discount diflucan 150mg online fungus gnat treatment uk. Vitamin B6 supplementation appears to offer significant protection against the development of diabetic neuropathy diflucan 50mg low price antifungal treatment for thrush. Individuals who have long-standing diabetes or who are developing signs of peripheral nerve abnormalities should definitely supplement their diets with vitamin B6 order diflucan 200mg with visa fungus and cancer. Vitamin B6 supplementation can be a safe and effective treatment for gestational diabetes (diabetes caused by pregnancy) diflucan 200 mg free shipping fungus killer for wood. One study of 14 women with gestational diabetes given 100 mg vitamin B per day for two weeks resulted in eliminating the diagnosis in 12 of the 14 women. Considerable evidence indicates that diabetics should take supplemental magnesium, the reasons being that more than half of all people with diabetes show evidence of magnesium deficiency and magnesium may prevent some of the complications of diabetes such as retinopathy and heart disease. Magnesium levels are usually low in diabetics and lowest in those with diabetic complications such as retinopathy and neuropathy. Diabetics may need twice this amount because they tend to lose excessive magnesium through their kidneys. Although magnesium occurs abundantly in whole foods, food processing refines out a large portion of a food’s magnesium. The best dietary sources of magnesium are tofu, seeds, nuts, and green leafy vegetables. Most Americans consume a low-magnesium diet because their diet is high in refined foods, meat, and dairy products. In addition to eating a diet rich in magnesium, diabetics should supplement their diet with 300 to 500 mg magnesium daily. For best results, highly absorbable sources of magnesium such as magnesium aspartate or citrate should be taken. Diabetics should also be sure to get at least 25 mg vitamin B6 per day, as the level of vitamin B6 inside the cells of the body appears to be intricately linked to the magnesium content of the cell. In other words, without vitamin B6 (as well as vitamin E), magnesium will not get inside the cell and will therefore be useless. Zinc functions in more enzymatic reactions than any other mineral, as it is a cofactor in more than 200 different enzymes. Although severe zinc deficiency is rare in developed countries, many individuals in the United States have marginal zinc deficiency. This is particularly true of the elderly population, as well as of people with diabetes. Low levels of zinc in the body are associated with increased susceptibility to infection, poor wound healing, a decreased sense of taste or smell, or skin disorders. It has also been suggested that zinc deficiency, like chromium deficiency, plays a role in the development of diabetes. Zinc also has a protective effect against beta cell destruction and has well-known antiviral effects. Diabetics typically excrete too much zinc in the urine and therefore require supplementation. Manganese functions in many enzyme systems, including those involved in blood glucose control, energy metabolism, and thyroid hormone function. In guinea pigs, a deficiency of manganese results in diabetes and an increase in the number of offspring that develop pancreatic abnormalities or have no pancreas at all. Diabetics have been shown to have only one-half the manganese of normal individuals. Biotin is a member of the B vitamin family and functions in the manufacture and utilization of carbohydrates, fats, and amino acids. Biotin supplementation has been shown to enhance insulin sensitivity and increase the activity of glucokinase, the enzyme responsible for the first step in the utilization of glucose by the liver. Evidently, supplementing the diet with high doses of biotin improves glucokinase activity and glucose metabolism in diabetics. In one study, 16 mg biotin per day resulted in significant lowering of fasting blood glucose levels and improvements in blood glucose control in type 1 diabetics. In another study, involving type 2 diabetics, similar effects were noted with 9 mg biotin per day. They offer significant protection against heart disease in diabetes, helping to lower lipids and blood pressure. Omega-3 oils are usually nearly completely lacking in the basic diet of a diabetic patient. Foods that contain omega-3s include oily fishes such as wild salmon, anchovies, sardines, herring, trout, and mackerel; walnuts; grass-fed beef; wild game meat; omega-3 eggs; and ground flax, hemp, and chia seeds. Initially there were concerns that omega-3 fatty acid supplementation might adversely affect blood glucose control, but two intensive investigations, one conducted at Oxford University and the other at the Mayo Clinic, analyzed data from 18 double-blind clinical trials involving 823 participants followed for an average of 12 weeks. Reducing After-Meal Elevations in Blood Glucose Levels Elevations of blood glucose levels after a meal can wreak biochemical havoc in both type 1 and type 2 diabetics. In fact, an elevation in postprandial blood glucose levels is the major contributor to the development of diabetic complications, especially cardiovascular disease and diseases of the microvasculature (retinopathy, neuropathy, and nephropathy). For example, patients who have a normal fasting blood glucose measurement but an average 2-hour postprandial glucose level greater than 200 mg/dl (11 mmol/l) have a threefold increase in the incidence of diabetic retinopathy. In addition to low-glycemic-load meals, several natural products can be used to reduce postprandial blood glucose levels. The best supplements to use in this regard are fiber supplements and natural glucosidase inhibitors. Fiber supplements have been shown to enhance blood glucose control, decrease insulin levels, and reduce the number of calories absorbed by the body. The best fiber sources for these purposes are those that are rich in soluble fiber, such as glucomannan (from konjac root), psyllium, guar gum, defatted fenugreek seed powder or fiber, seaweed fiber (alginate and carrageenan), and pectin. Clinical studies have repeatedly shown that after-meal blood glucose levels decrease as soluble fiber viscosity increases. One of the most viscous naturally occurring dietary fibers is glucomannan, a soluble fiber obtained from the root of konjac, a plant that has been used as a food and remedy for thousands of years in Asia. Highly refined glucomannan possesses the greatest viscosity of any single dietary fiber. It is three times more viscous than guar and approximately seven times more viscous than psyllium. Starches, complex carbohydrates, and even simple sugars (disaccharides) such as sucrose are broken down in the digestive tract into glucose by the action of certain enzymes. Among the most important enzymes are the alpha-glucosidases, found in the intestines. Because these enzymes are essential for the breakdown of starches, complex carbohydrates, maltose, and sucrose into absorbable glucose molecules, their inhibition can diminish the after-meal rise in both glucose and insulin. Acarbose (Precose) and miglitol (Glyset) are approved drugs for treating diabetes by inhibiting alpha-glucosidase. Although clinical studies have shown them to be quite effective, they are also characterized by a high frequency of mild to moderate gastrointestinal side effects such as flatulence, diarrhea, and abdominal discomfort. Although these side effects generally diminish in frequency and intensity with time, few patients are willing to put in the necessary time to get over them. Instead of the drug acarbose, we recommend trying extracts of either touchi or mulberry, which are natural and superior to their drug counterparts. Touchi is a fermented soybean product that has been used in China and Japan for more than 3,000 years.

diflucan 200mg low price

The most general curve-fitting method in general use is that of maximum-likelihood order 150mg diflucan amex fungus gnats with no plants. Finney has compared this method to the more commonly encountered technique of least squares and found the latter satisfactory for routine use (101) discount diflucan 50mg without prescription fungus gnats cactus. S o m e of the simpler calibration methods use linear least squares discount 150mg diflucan with visa antifungal vitamins herbs, but the more advanced methods require the more complex non-linear least square technique order 200 mg diflucan fast delivery antifungal cream for face. In either case, it is vitally important to weight the fit to take into account the heteroscedasticity (non-uniformity of variance) almost invariably found in the response (121). Methods of assessing the quality of fit include analysis of variance (which are exact only in the case of linear least squares models) and the plotting of residuals. A very clear graphic technique embodied in the programs of Dudley (79) and Malan (4) plots the difference between the known and predicted analyte concentrations of the standards, with the predicted values being bracketed by their confidence limits. This allows a rapid check to see if the irregularity in the fit is much smaller than the random error present, which would normally be expected if the selected calibration method is appropriate for the assay at hand. If a device is being selected especially for the purpose of assay data analysis, there is a huge choice, from inexpensive hand-held calculators to large computers. Factors in the decision should include not only the price of the device, but also ease of use, maintainability, and reliability. The flexbility of the device is greatly extended if it can be attached to other computing devices and to laboratory equipment. It is important to select a program which is written using good modular structured programming techniques so that it will be easy to correct and to improve. The program should also extract the maximal amount of information possible from the data, in accordance with accepted practice. The majority of the programs indexed in Table 1 do not perform the basic set of procedures outlined in section 2. Rather than review the entire list of available programs, it seems more useful to put forward several examples of carefully executed and comprehensively conceived programs which run on a variety of computing devices. For computers capable of handling a moderately large F O R T R A N program, the package of Raab, McKenzie, and Thompson would seem to be the most flexible and powerful program currently available (73,74). Also well suited are the pioneering programs of Rodbard (48), and the program of Peters (75). The F O R T R A N programs of Finney (68) and Healy (53) are well executed but evidently not intended for routine laboratory use. It is attractive and easy to use, but Finney has expressed some mild misgivings about certain statistical aspects of the multi-binding site model it uses to fit the calibration curve (117). These seem relatively minor but still have not been discussed in print by the developers of the program. One advantage of this and the larger F O R T R A N programs is that data entry is relatively easily done by use of punched paper tape output taken directly from the final measurement device of the assay. This program goes well beyond previous calculator programs, which are essentially simply calibration and interpolation programs (54,78), and offers a very comprehensive analysis of results. Nevertheless, this program establishes a new minimum level of acceptable statistical capability for assay programs in general. The use of any of these programs may require that additional programming be done at the local level. The language of alphanumeric prompts m ay need to be modified to suit the local workers. Interfacing the assay program with pre-existing laboratory data management programs m a y be necessary. Finney has outlined the characteristics of an ideal assay program (117); the requirements make it clear that writing a complete package is not a trivial task. It is to the benefit of both individual laboratories and the assay community as a whole to concentrate upon the dissemination and continued improvement of several good programs rather than the continued development of many local programs. This will probably lead to increased use of disseminated processing in laboratories, in which small special- purpose computing devices are attached to assay machinery and used strictly for assay calculations. These small machines will communicate with a hierarchy of other larger machines to pass on results to a data archive. It is possible that robust statistical techniques (67,119,120) will be incorporated into programs, with due caution (121), to facilitate the recognition and rejection of outliers. Another possibility is the use of more general curve-fitting methods such as the maximum-likelihood based method known as "extended least squares" (122), which essentially attempts to fit both a calibration curve and an imprecision profile, simultaneously and using the same data. Such a technique would very likely have to pool information from several assays, as is done at present, because there is rarely sufficient statistical information about imprecision present in a single assay run. Thus far, the most satisfactory programs have come from academic and public institutions, rather than the commercial sector. However, it is possible that future programs will make use of the experience which industry (most notably the home computer industry) has acquired in making programs attractive to use, and in making the documentation complete and easy to understand. Another important goal should be to standardize the mathematical techniques used so that quantities such as imprecision are computed identically everywhere; this would facilitate the comparison of assay methods and results. C O N C L U D I N G R E M A R K S Although the increase in speed, decrease in cost, and decrease in variability of results which come from the proper application of an automated data processing technique are well documented (114,123), perhaps the most salutory effect is that the attention of the assayist is focussed more clearly on maximally meaningful indices of assay performance (inprecision and bias) rather than statistically meaningless criteria such as calibration curve slope and location. Contrary to the objections of impracticality voiced at prior meetings of this type (and which will doubtless be raised again at this conference), the procedures outlined in this paper are not the abstract pipe dreams of mathematicians. The programs described here were developed with the close attention of working essayists and are in daily use in major medical institutions throughout the world. The major impediments to their more widespread use would seem to be social and educational rather than truly practical. Even the most sophisticated of programs can only supplement, and not supplant, the practical experience and judgment of the assayist, and occasional problems will still call for the advice of a biostatistician. The ultimate determinants of assay quality will remain the talent and motivation of the individuals involved in performing the assay: the judicious selection and critical application of a comprehensive automated data processing and quality control package will be an important reflection of this talent and motivation. Rodbard (National Institutes of Health) for sending m e copies of their software, as well as pertinent reprints. Edwards (Middlesex Hospital, London) who has taken over development of the program originated by P. Ekins expressed his preference for the term precision profile rather than imprecision profile, the concept of precision being a general one which could be expressed in terms of a wide variety of metameters. A question related to the distinction between the valid analytical range of an assay as defined by Mr. Rodgers and its working range for a chosen maximum coefficient of variation, derived from its imprecision profile. The working range derived as described from the imprecision profile was entirely arbitrary, depending on the magnitude of the coefficient of variation chosen. Ekins, for his part, preferred to retain sensitivity to denote the impreci­ sion of measurement at zero dose. A speaker questioned whether quality-control indices as numerous as those listed by Mr. Rodgers saw no difficulty here, provided that data-processing programs were properly designed. The information to be imparted was limited; displaying it was the task of the programmer. As a minimum, the results of each assay should be given with confidence limits, the imprecision profiles should be presented and so also should the results of tests for drift and bias. Results of additional tests for between- assay variation in these quality control indices should be presented as appropriate.

To do this, it needs to identify the word, “stay” with some negative visual signal (eg, holding the hand up with the flat palm facing the bird, or holding a large black object in front of the bird). If the bird tries to move or bite, the visual signal is offered with the word “stay”. If the bird responds (a response in this case is lack of movement), it should be verbally praised. When the “stay” command is mastered and the bird has successfully responded ten times in a row, the training can move to Stage 2. First issue the “stay” directive, even as the hand-held perch is being presented (without the “up” command).

In the last 30 years, black cohosh (Cimicifuga racemosa) has emerged as the most frequently studied of the herbal alternatives to hormone replacement therapy for menopausal symptoms. The collective findings of studies involving black cohosh and long-term clinical anecdotal evidence indicate that it is most effective for hot flashes (both during the day and at night), mood swings, sleep disorders and body aches. In perhaps the most detailed double-blind study to date, black cohosh extract was evaluated for its effect on menopausal symptoms, bone metabolism, and the lining of the uterus (endometrium). Results indicated that the black cohosh extract was equal to the conjugated estrogens and superior to the placebo in reducing menopausal complaints. Both black cohosh extract and the conjugated estrogens produced beneficial effects on bone metabolism, but the black cohosh extract had no effect on endometrial thickness, which was significantly increased by the conjugated estrogens (increased endometrial thickness is associated with a higher rate of uterine cancer). Vaginal superficial cells were increased with both black cohosh and conjugated estrogens. These results seem to confirm that black cohosh extracts contain substances with selective estrogen-receptor-modifying activity—that is, it shows positive effects in the brain/hypothalamus, bone, and vagina, but has no cancer-causing effects on the uterus. Some recent studies have used black cohosh extract in combination with other botanical extracts. A clinical trial involving 125 menopausal women showed that a combination of 40 mg black cohosh extract, 12 mg isoflavones from red clover, 60 mg isoflavones from soy, 30 mg chasteberry extract, 250 mg valerian extract, and 121 mg vitamin E resulted in a significant lowering of menopausal symptoms after four and six months. Maca (Lepidium meyenii) is an herbal remedy from Peru most often thought of as enhancing male sexuality, but it also has effects on women. Thus maca tends to work on all of a woman’s menopausal symptoms instead of on any one specific symptom alone, such as hot flashes. The maca also had a small effect on increasing bone density and alleviated numerous menopausal symptoms including hot flashes, insomnia, depression, nervousness, and diminished concentration. There were no changes in hormone levels, but there was a significant reduction in anxiety, depression, and sexual dysfunction with maca consumption compared with the baseline and the placebo. Red clover (Trifolium praetense), a member of the legume family, has been used worldwide as a source of hay for cattle, horses, and sheep and by humans as a source of protein (leaves and young sprouts). Historically, it has also been recognized as a medicinal plant for humans and, more recently, as a menopausal herb. At least six clinical trials have been conducted on the effect of red clover isoflavones on vasomotor symptoms; about half show benefit and the others do not. The first two published studies on red clover and hot flashes showed no statistically significant difference between the red clover standardized extract and a placebo during a three-month period, although both groups did improve. In the first study red clover extract produced a 75% reduction in hot flashes after 16 weeks in 30 women. In the first study, 80 mg isoflavones per day resulted in a significant reduction in hot flashes as compared with baseline. Dong quai (Angelica sinensis) is one of the most famous herbal remedies in China, where it is often referred to as “female ginseng. Although a double-blind, placebo-controlled study in women showed no significant benefit, the preparation used (a dried aqueous extract) was clearly lacking some of the important volatile compounds, though it was standardized for ferulic acid content. Also, in a double-blind study, the combination of 100 mg dong quai extract, 60 mg soy isoflavones, and 50 mg black cohosh extract significantly reduced menstrual migraines. Saint-John’s-wort ( Hypericum perforatum) extract research has focused on the area of mild to moderate depression. A recent randomized, double-blind, placebo-controlled clinical trial studied Saint-John’s- wort in perimenopausal/menopausal hot flashes. Clinical exams and interviews were performed at baseline, four weeks, and eight weeks. In women taking Saint-John’s-wort, the frequency of hot flashes began to decline during the first month and showed more improvement during the second month. The decline in duration and severity of hot flashes was statistically significant at week eight and the decline was much more evident in the Saint-John’s-wort group. Another double-blind randomized clinical trial studied the effect of Saint-John’s-wort extract on the symptoms and quality of life of 47 symptomatic perimenopausal women age 40 to 65 with three or more hot flashes per day. After 12 weeks of treatment, a nonsignificant difference in favor of the Saint-John’s-wort group was observed in daily hot flash frequency and hot flash score. After three months of treatment, women in the Saint-John’s-wort group reported significantly better quality-of-life scores and significantly fewer sleep problems compared with the placebo group. One study of women with menopause symptoms using 900 mg Saint-John’s-wort extract for 12 weeks found that about three-quarters of the women experienced improvement in both psychological and psychosomatic menopausal symptoms as well as a feeling of sexual well-being. For information on possible drug interactions with Saint-John’s-wort, see the chapter “Depression. EstroG is an herbal product containing a mixture of standardized extracts of Cynanchum wilfordii, Phlomis umbrosa, and Angelica gigas that has shown favorable results in clinical studies. In the most detailed double-blind study, 64 pre-, peri-, and postmenopausal women were randomly assigned to take either EstroG (517 mg per day) or a placebo for 12 weeks. Statistically significant improvement in vaginal dryness in the EstroG group was also observed. However, premature menopause, surgical menopause, or medication- induced menopause is not normal, and the benefits and risks should be addressed individually under the guidance of a physician. However, for women at high risk for osteoporosis and women who have already experienced significant bone loss and also have menopause symptoms or do not tolerate osteoporosis medications, hormonal therapy may be indicated. Exercise Engage in a regular exercise program according to the recommendations in the chapter “A Health-Promoting Lifestyle. Perhaps the most important dietary recommendation may be to increase consumption of plant foods, especially those high in phytoestrogens, while reducing the consumption of animal foods. As with any disease, proper determination of the cause is essential for effective treatment. Physicians often believe they can assess menstrual blood loss by asking the patient to estimate the number of pads or tampons used during each period and the duration of the period. However, studies have demonstrated that there is no correlation between measured blood loss and these assessments. Excessive blood loss should be a concern if a woman is bleeding longer than 7 straight days or more frequently than every 21 days, and is changing a pad or tampon every hour for more than half a day. Women who are changing a pad and/or tampon every half hour or at even shorter intervals often require urgent, perhaps emergency, attention. Symptoms such as lightheadedness, dizziness, and fainting are cause for immediate concern. Any amount of bleeding in a postmenopausal woman not taking hormone replacement therapy is considered abnormal. Another cause of functional menorrhagia is abnormalities in arachidonic acid metabolism. The endometrium of women who have menorrhagia concentrates arachidonic acid to a much greater extent than normal, resulting in increased production of series 2 prostaglandins, which are thought to be the major factor both in the excessive bleeding and in the accompanying menstrual cramps. Even minimal thyroid dysfunction may be responsible for menorrhagia and other menstrual disturbances. Although menstrual blood loss is well recognized as a major cause of iron deficiency anemia in fertile women, it is not as well known that chronic iron deficiency can be a cause of menorrhagia. This assertion is based on several observations:7 • Response to iron supplementation alone in 74 of 83 patients (in whom organic disease had been excluded) • A significant double-blind placebo-controlled study displaying improvement in 75% of those given iron supplementation, compared with 32. In one study, women who were menorrhagic had significantly lower serum ferritin levels than controls, but other iron indicators such as hemoglobin concentration, mean corpuscular volume, and mean corpuscular hemoglobin were not significantly different between the two groups.

Absorption depends on many factors order diflucan 200mg mastercard antifungal imidazole, including sex and weight of the individual order diflucan 200 mg mastercard anti fungal paint additive, duration of drinking buy discount diflucan 200 mg fungus gnats worm bin, nature of the drink order diflucan 200mg overnight delivery antifungal liquid review, and presence of food in the stomach. Alcohol dehydrogenase in the gastric mucosa may contribute substantially to alcohol metabolism (gastric first-pass metabolism), but this effect is generally only evident with low doses and after eating. Studies of alcohol dehydrogenase activity in gastric biopsies of women suggest a significant decrease in activity in women compared with men, which could explain why women have higher peak blood alcohol levels and are more susceptible to liver damage after con- sumption of smaller quantities of alcohol when compared with men (16). Once absorbed, alcohol is eliminated at a fairly constant rate, with 90% being metabolized in the liver and the remainder excreted unchanged in urine, breath, and sweat. The rate of elimination in moderate drinkers may vary between 10 and 20 mg/100 mL blood/h, with a mean of 15 mg/100 mL blood/ h. Chronic alcoholics undergoing detoxification have elimination rates of 19 mg/100 mL blood/h or even higher (17). Even at low doses, there is clear evidence that alcohol impairs performance, especially as the faculties that are most sensitive to alcohol are 356 Wall and Karch those most important to driving, namely complex perceptual mechanisms and states of divided attention. In a review of more than 200 articles (18), sev- eral behavioral aspects were examined, including reaction time, tracking, concentrated attention, divided attention, information processing, visual function, perception, psychomotor performance, and driver performance. Most of the studies showed impairment at 70 mg/100 mL of blood, but approx 20% showed impairment at concentrations between 10 and 40 mg/ 100 mL of blood. The definitive study on the relationship between risk of accident and blood alcohol concentration is that conducted in the 1960s in Grand Rapids, Mich. Compari- son of the two groups disclosed that an accident was statistically more likely at blood alcohol levels greater than 80 mg/100 mL of blood, with accidents occurring more frequently as follows: Blood alcohol (mg/100 mL) Accident occurrence 50–100 1. On average, the risk doubles at 80 mg/ 100 mL, increasing sharply to a 10 times risk multiplier at 150 mg/100 mL and a 20 times risk multiplier at 200 mg/100 mL of blood. For inexperienced and infrequent drinkers, the sharp increase occurs at much lower levels, whereas for the more experienced drinking driver it may not occur until 100 mg/100 mL (Fig. Therefore, this research has encouraged some countries to have a lower blood alcohol level for legal driving; in Australia, Canada, and some states of the United States, different levels and rules are applied for younger and/ or inexperienced drivers (see Subheading 3. Further evidence of the rela- tionship between crash risk and blood alcohol levels has been shown by Compton and colleagues (21), who studied drivers in California and Florida. This recent research studying a total of 14,985 drivers was in agreement with previous studies in showing increasing relative risk as blood alcohol levels increase, with an accelerated rise at levels in excess of 100 mg/100 mL of blood. However, after adjustments for missing data (hit-and-run driv- ers, refusals, etc. Risk of road traffic accidents related to level of alcohol in the blood and breath. Road Traffic Legislation In the United Kingdom, this research led to the introduction of the Road Safety Act 1967, which set a legal driving limit of 80 mg/100 mL of blood (or 35 µg/100 mL of breath or 107 mg/100 mL of urine). This law also allows mandatory roadside screening tests and requires the provision of blood or urine tests at police stations. The Transport Act 1981 provided that quantitative breath tests, performed with approved devices, could be used as the sole evidence of drunk driving. In the United States, permissible blood levels vary from state to state and also by age. Many states have enacted “zero tolerance” laws, and the detection 358 Wall and Karch of any alcohol in an individual younger than 21 years old is grounds for license revocation. Some states permit levels as high as 100 mg/100 mL, but most enforce the same limit as in the United Kingdom, and legislation to reduce the 80 mg/100 mL level further is under consideration. Equivalent Limits in Other Body Fluids Statutes have been used to establish blood alcohol concentration equiva- lents in other tissues and breath. Not infrequently, alcohol concentrations will be measured in accident victims taken for treatment at trauma centers. How- ever, there are two important differences between alcohol measurements made in hospitals and those made in forensic laboratories; first, in hospitals, stan- dard international units are the norm, the mole is the unit of mass, the liter is the unit of volume, and alcohol concentrations are reported in mmol/L. In forensic laboratories, results are expressed as gram/deciliter or liter, or even milligrams per milliliter, and measurements are made in whole blood, not serum or plasma. There is another, even more important, difference between serum/plasma and whole blood. Because alcohol has a large volume of distribution, this difference in water content means that alcohol concentrations measured in serum/plasma will be higher than concentrations measured in whole blood by approx 14%. In practice, if plasma alcohol concentrations are to be intro- duced as evidence, they should be related back to whole blood concentrations using an even higher ratio (1. As mentioned, if whole blood is tested, drivers are not usually prosecuted at blood levels below 87 mg/100 mL of blood (17). The instruments used are cali- brated to estimate the concentrations of alcohol in whole blood, not plasma or serum. To estimate the serum or plasma alcohol concentration from breath measurements, a plasma/breath ratio of 2600:1 must be used (because, as explained, whole blood contains 14% less alcohol). In Europe, but not neces- sarily in the United States, two specimens of breath are taken for analysis, and the specimen with the lower proportion of alcohol should be used as evidence. Bladder urine, because it contains alcohol (or other drugs) that may have accumulated over a long period, is generally not considered a suitable speci- men for forensic testing, especially because the presence of alcohol in the Traffic Medicine 359 Table 1 Prescribed Blood Alcohol Levels in Various Jurisdictions Australia 50 France 50 Poland 20 Austria 80 Germany 80 Romania 0 Belgium 80 Greece 50 Russia 0 Bulgaria 0 Hungary 0 Sweden 20 Canada 80 Italy 80 Spain 80 Czechoslovakia 80 Luxembourg 80 Turkey 0 Denmark 80 Netherlands 50 United States 100a Ireland 80 Norway 50 Yugoslavia 50 Finland 50 aSome states in the United States have reduced the legal level to 80 mg/100 mL of blood. Alcohol concentrations in bladder urine cannot be used to infer the blood levels reliably. Under the new California provisions, police can still request a urine test if a suspect’s breath test is negative (22). Com- parison of alcohol concentrations in vitreous and blood can provide a good indication of whether concentrations were rising or falling at the time of death (alcohol is distributed mainly in water and the water content of vitreous is lower than that of blood). Urine obtained from the kidney pelvis can also be used, because its alcohol content can be precisely related to blood concentra- tion (23). Legal Limits in Other Jurisdictions Table 1 shows permissible alcohol limits for various countries. All fig- ures are the maximum permissible amount in milligrams per 100 mL of blood (in the United States, referred to as deciliters [dL]). Although legislation has been introduced to enforce uniform standards, these standards have not been enacted, and in the United States, permissible alcohol levels vary from state to state. Countermeasures Numerous measures have already been taken to discourage drivers from drinking, and they have had a considerable degree of success. Lowering the Legal Limit When the legal limit was reduced in Sweden from 50 to 20 mg, there was a fall in casualties (24). It has been estimated that a similar reduction in the United Kingdom would save 50 lives, prevent 250 serious injuries, and elimi- nate another 1200 slight injuries each year. Widening Police Breath-Testing Powers Currently in the United Kingdom, a police officer may stop any person driving a motor vehicle on the road, but that does not necessarily mean that the officer can administer a breath test. As is the case in the United States, police officers can require a breath test only if there is reasonable cause to suspect that the person detained has alcohol in his or her body, has committed a moving traffic offense, or has been involved in an accident. In Finland, random breath testing, along with a legal limit of 50 mg/ 100 mL of blood, was introduced in 1977; highly visible check points are established where typically 8–12 police officers with breath alcohol screen- ing devices are placed along the center of the road, the sites being chosen so that it is impossible for a driver to avoid being tested. The procedure takes only seconds to perform, the system receives general public support (26), and it has resulted in a marked reduction in the number of accidents and injuries. In the state of Victoria, Australia, “booze buses” are set up along with a roadblock—any driver who fails a roadside breath test is taken into the bus and given an evidentiary breath test (Drager 7100 machine). Every driver in Victoria is said to be tested on average at least once a year (27). Ignition Interlocks for Repeat Drunk-Driving Offenders These devices prevent the car ignition from being started unless the concentration of breath alcohol blown into the device is below a predeter- mined level, often well below the legal limit. Thereafter, during the journey, the driver is required to undertake random rolling retests. These devices have been used in several states of the United States and also in Alberta, Canada.

Antivenin is specifc for each group of snakes; the local Poison Control Center may be helpful in determining the need. The majority of snakes are nonpoi- sonous but two major groups do pose a threat: crotalids (pit vipers including rattlesnakes, cotton mouths) and elapids (coral snakes, cobras). Crotalid venom is predominantly cytolytic and may cause edema, hemorrhage, and necrosis close to and far away from the bite. Systemic signs and symptoms may include hemolysis, thrombocytopenia, disseminated intravascular coagul- opathy, vomiting, and cardiovascular and respiratory failure. Elapids tend to have neurotoxic venom producing neurological symptoms (dip-Elapids tend to have neurotoxic venom producing neurological symptoms (dip- lopia, ptosis, respiratory depression, parasthesia).

No fever, chills, nausea, vomiting, chest pain, shortness of breath, trauma, numbness, tingling, and weakness noted. Fundoscopic examination demon- strates intraretinal blood and macular edema, intraocular pressures normal c. Neuro: alert and oriented, no focal motor, sensory defcits; no neglect with left eye; no facial asymmetry; normal memory; gait normal i. Examination demonstrates unremarkable sclera, conjunctiva, and anterior chamber in both eyes. This is a case of central retinal vein occlusion or blockage of blood fow to the eye. If neurology consultation is attempted, the consultant will defer to the ophthalmologist’s recommenda- tions. Patients should be referred to oph- thalmologist within 24 hours for assessment of possible glaucoma or other pathologies. Optic disc edema and diffuse retinal hemorrhages in all quadrants are patho-Optic disc edema and diffuse retinal hemorrhages in all quadrants are patho- gnomonic for central retinal vein occlusion. Ophthalmoscopic examination reveals dilated and tortuous veins, retinal and macular edema, diffuse retinal hemorrhages and attenuated arterioles. An affer- ent pupillary defect may be noted in the affected eye – loss of vision in that eye prevents light information from being relayed to the brain. Thus, light shone Case 16: Visual impairment Case 17: syncope 89 in the affected eye will not be perceived, and the pupils dilate. When light is directed into the unaffected eye, the information is transmitted to the brain normally, and both pupils receive a signal to constrict. Optic neuritis, though often presenting with similar symptoms as retinal vein occlusion, can be excluded as it is devoid of peripheral hemorrhage on examination. During exercise she developed palpitations and shortness of breath followed by fainting. Social: lives with parents at home, denies alcohol use, smoking, drugs, or sex- ual activity f. Patient remains in ventricular fbrillation/torsades until two shocks and magnesium are administered. Once torsades occurs as in this patient, magnesium sulfate is the drug of choice for conversion, but unstable patients need defbrillation. Postarrest care includes an antiarrhythmic like lidocaine as with any severe arrhythmia. Comfortable appearing male, slightly drooling and sitting upright, holding head and neck still.

General: alert, oriented × 3, sitting upright in stretcher, holding head and neck in a fxed position, slightly drooling b. Neck: no stridor, no anterior cervical lymphadenopathy, pain with extension of neck g. Surgery – otolaryngology – assessment shows swelling in soft tissue around the posterior pharynx, normal vocal cords without edema, patent airway. This is a case of retropharyngeal abscess, a serious infection of the soft tis- sue behind the pharynx, which can in severe circumstances lead to a clos- ing of the airway and inability to breath. The patient’s symptoms of drooling, fever, sore throat, and neck stiffness are key fndings. If the candidate does not order antibiotics, the patient will become more short of breath. If surgery or Case 18: sore Throat Case 19: knee Pain 97 otolaryngology is not consulted, the patient will have increased diffculty in breathing and agitation. On physical exam- ination, note the resistance to neck movement (with extension greater than fexion in the midline). Some patients are mistakenly worked up for meningitis because of the neck stiffness. Alternative diagnoses, such as epiglottitis and peritonsillar abscess, must be considered as well. Although a lateral soft tissue neck radiograph is a good initial imaging study, it requires patient cooperation, which can be diffcult in pediatric patients. Otherwise, you may obtain a falsely positive study in which you see widening of the pre- vertebral space as an artifact. The prever- tebral space is widened if it is greater than 7 mm at C2 or 14 mm at C6. The most common organisms are gram positives, specifcally group A Streptococcus and Staphylococcus aureus. Late fndings include extension into the mediastinum, airway compromise from abscess rupture, or direct pressure.

This is a case of slipped capital femoral epiphysis, the most common cause of hip disability in adolescents. In this injury, the growth plate near the end of the femur becomes disrupted, and the end of the bone “slips” out of place. Important early actions include physical examination of the hips and x-ray imaging of the hips bilaterally including lateral views. If the patient is discharged without a hip exam- ination or x-ray, the patient will return 2 days later unable to walk.
