Large calendar purchase vermox 100 mg mastercard, indicating one day at a time order 100mg vermox free shipping, with month purchase vermox 100 mg otc, day, and year identified in bold print. Printed, structured daily schedule, with one copy for client and one posted on unit wall. If verbalizations are not understandable, express to client what you think he or she intended to say. Reminiscence and life review help client resume progression through the grief process associ- ated with disappointing life events and increase self-esteem as successes are reviewed. Caregiver may need to accompany client at first, until he or she feels secure that group members will be accepting, regardless of limita- tions in verbal communication. Offer support and empathy when client expresses embar- rassment at inability to remember people, events, and places. Client initiates own self-care according to written schedule and willingly accepts assistance as needed. Client interacts with others in group activities, maintaining anxiety at minimal level in response to difficulties with ver- bal communication. Possible Etiologies (“related to”) Severity of care receiver’s illness Chronicity of care receiver’s illness [Lack of respite and recreation for caregiver] Caregiver’s competing role commitments Inadequate physical environment for providing care Family or caregiver isolation Complexity and amount of caregiving activities Defining Characteristics (“evidenced by”) Apprehension about possible institutionalization of care receiver Apprehension about future regarding care receiver’s health and caregiver’s ability to provide care Difficulty performing and/or completing required tasks Apprehension about care receiver’s care if caregiver unable to provide care Goals/Objectives Short-term Goal Caregivers will verbalize understanding of ways to facilitate the caregiver role. Long-term Goal Caregivers will demonstrate effective problem-solving skills and develop adaptive coping mechanisms to regain equilibrium. Caregivers may be unaware of what client will realistically be able to accomplish. Ensure that caregivers are aware of available community support systems from which they can seek assistance when required. Examples include adult day-care centers, house- keeping and homemaker services, respite-care services, and a local chapter of the Alzheimer’s Association. This organization sponsors a nationwide 24-hour hot line to provide information and link families who need assistance with nearby chapters and affiliates. Caregivers require relief from the pressures and strain of providing 24-hour care for their loved ones. Release of these emotions can serve to prevent psychopathol- ogy, such as depression or psychophysiological disorders, from occurring. Encourage participation in support groups composed of members with similar life situations. Hearing others who are experiencing the same problems discuss ways in which they have coped may help caregiver adopt more adaptive strate- gies. Individuals who are experiencing similar life situations provide empathy and support for each other. Caregivers are able to problem solve effectively regarding care of elderly client. Caregivers demonstrate adaptive coping strategies for dealing with stress of caregiver role. Other substance-induced disorders (delirium, dementia, am- nesia, psychosis, mood disorder, anxiety disorder, and sexual dysfunction) are included in the chapters with which they share symptomatology (e. Substance Dependence Defined “Dependence” is defined as a compulsive or chronic requirement. The need is so strong as to generate distress (either physical or psychological) if left unfulfilled (Townsend, 2009). Dependence on substances can also be associated with tolerance, in which there is a need for increasingly larger or more frequent doses of a substance to obtain the desired effects originally produced by a lower dose. The individual who is dependent on substances continues to increase the amount consumed to achieve the desired effect and to relieve or avoid withdrawal symptoms. With substance intoxication, the individual experiences a reversible syndrome of symptoms that occur with ingestion of a substance and that are specific to the substance ingested. Substance Withdrawal Defined “Withdrawal” is defined as the physiological and mental read- justment that accompanies the discontinuation of an addictive substance (Townsend, 2009). The symptoms of withdrawal are specific to the substance that has been ingested and oc- cur after prolonged or heavy use of the substance. The effects are of sufficient significance to interfere with usual role performance. Low to moderate consumption produces a feeling of well-being and reduced inhibitions. At higher concentra- tions, motor and intellectual functioning are impaired, mood becomes very labile, and behaviors characteristic of depres- sion, euphoria, and aggression are exhibited. The only medical use for alcohol (with the exception of its inclusion in a number of pharmacological concentrates) is as an antidote for methanol consumption. Common substances containing alcohol and used by some dependent individuals to satisfy their need include liquid cough medications, liquid cold preparations, mouthwashes, isopropyl Substance-Related Disorders ● 73 rubbing alcohol, nail polish removers, colognes, and aftershave and preshave preparations. Opioids Opioids have a medical use as analgesics, antitussives, and an- tidiarrheals. They produce the effects of analgesia and euphoria by stimulating the opiate receptors in the brain, thereby mim- icking the naturally occurring endorphins.

Individu- als with hypochondriasis often have a long history of “doctor shopping” and are convinced that they are not receiving the proper care discount 100 mg vermox overnight delivery. Conversion Disorder Conversion disorder is a loss of or change in body function re- sulting from a psychological conflict discount vermox 100mg amex, the physical symptoms of which cannot be explained by any known medical disorder or pathophysiological mechanism buy generic vermox 100 mg. The most common conversion symptoms are those that suggest neurological disease such as paralysis, aphonia, seizures, coordination disturbance, akinesia, dyskinesia, blindness, tunnel vision, anosmia, anesthesia, and paresthesia. Body Dysmorphic Disorder This disorder, formerly called dysmorphophobia, is charac- terized by the exaggerated belief that the body is deformed or defective in some specific way. Studies have shown an increased incidence of somatization disorder, conversion disorder, and hypo- chondriasis in first-degree relatives, implying a possible inheritable predisposition (Sadock & Sadock, 2007; Soares & Grossman, 2007; Yutzy, 2003). Decreased levels of serotonin and endor- phins may play a role in the etiology of pain disorder. They hypothesize that physical complaints are the expression of low self- esteem and feelings of worthlessness and that the individual believes it is easier to feel something is wrong with the body than to feel something is wrong with the self. The psychodynamic theory of conversion disorder pro- poses that emotions associated with a traumatic event that the individual cannot express because of moral or ethical unacceptability are “converted” into physical symptoms. The unacceptable emotions are repressed and converted to a somatic hysterical symptom that is symbolic in some way of the original emotional trauma. Some families have difficulty expressing emotions openly and resolving conflicts verbally. When this occurs, the child may become ill, and a shift in focus is made from the open conflict to the child’s illness, leaving unre- solved the underlying issues that the family cannot confront openly. Thus, somatization by the child brings some stabil- ity to the family, as harmony replaces discord and the child’s welfare becomes the common concern. Somatic complaints are often reinforced when the sick role relieves the individual from the need to deal with a stressful situation, whether it be within society or within the family. When the sick per- son is allowed to avoid stressful obligations and postpone unwelcome challenges, is excused from troublesome du- ties, or becomes the prominent focus of attention because of the illness, positive reinforcement virtually guarantees repetition of the response. Personal experi- ence, or the experience of close family members, with seri- ous or life-threatening illness can predispose an individual to hypochondriasis. Once an individual has experienced a threat to biological integrity, he or she may develop a fear of recurrence. The fear of recurring illness generates an exaggerated response to minor physical changes, leading to hypochondriacal behaviors. Some cultures and religions carry implicit sanctions against verbalizing or directly expressing emotional states, thereby indirectly encouraging “more acceptable” somatic behaviors. Cross- cultural studies have shown that the somatization symp- toms associated with depression are relatively similar, but the “cognitive” or emotional symptoms such as guilt Somatoform Disorders ● 179 are predominantly seen in Western societies. In Middle Eastern and Asian cultures, depression is almost exclusively manifested by somatic or vegetative symptoms. Environmental influences may be significant in the predisposition to somatization disorder. Some studies have suggested that a tendency toward somatization appears to be more common in individuals who have low socioeconomic, occupational, and educational status. Any physical symptom for which there is no organic basis but for which evidence exists for the implication of psycho- logical factors. Impairment in social or occupational functioning because of preoccupation with physical complaints 10. Psychosexual dysfunction (impotence, dyspareunia [painful coitus], sexual indifference) 11. Excessive preoccupation with physical defect that is out of proportion to the actual condition Common Nursing Diagnoses and Interventions (Interventions are applicable to various health-care settings, such as inpatient and partial hospitalization, community outpatient clinic, home health, and private practice. Possible Etiologies (“related to”) [Severe level of anxiety, repressed] [Low self-esteem] [Unmet dependency needs] [Secondary gains from the sick role] Defining Characteristics (“evidenced by”) Verbal report of pain [in the absence of pathophysiological evidence] Reduced interaction with people Facial mask [of pain] Guarding behavior [Demanding behaviors] [Refuses to attend therapeutic activities because of pain] [History of seeking assistance from numerous health-care professionals] [Excessive use of analgesics, without relief of pain] Self-focusing Goals/Objectives Short-term Goal Within 2 weeks, client will verbalize understanding of correla- tion between pain and psychological problems. Long-term Goal By time of discharge from treatment, client will verbalize a noticeable, if not complete, relief from pain. Monitor physician’s ongoing assessments and laboratory re- ports to ascertain that organic pathology is clearly ruled out. Recognize and accept that the pain is real to the individual, even though no organic cause can be identified. Denying the client’s feelings is nontherapeutic and hinders the develop- ment of a trusting relationship. Identification of the precipitating stressor is important Somatoform Disorders ● 181 for assessment purposes. This information will be used to develop a plan for assisting the client to cope more adaptively. These distractors serve in a therapeutic man- ner as a transition from focus on self or physical manifes- tations to focus on unresolved psychological issues. Help client connect symptoms of pain to times of increased anxiety and to identify specific situa- tions that cause anxiety to rise. Verbalization of feelings in a nonthreatening environment facilitates expression and resolution of disturbing emotional issues. Explore ways to intervene as symptoms begin to intensify, so that pain does not become disabling (e.

What type of questions can psychologists answer that philosophers might not be able to answer as completely or as accurately? Explain why you think psychologists can answer these questions better than philosophers can. Choose one of the major questions of psychology and provide some evidence from your own experience that supports one side or the other. Choose two of the fields of psychology discussed in this section and explain how they differ in their approaches to understanding behavior and the level of explanation at which they are focused. The spandrels of San Marco and the Panglossian paradigm: A critique of the adaptationist programme. Unconscious cerebral initiative and the role of conscious will in voluntary action. On the inference of personal authorship: Enhancing experienced agency by priming effect information. Effects of subliminal priming of self and God on self- attribution of authorship for events. The cognitive neuroscience paradigm: A unifying metatheoretical framework for the science and practice of clinical psychology. Tightness-looseness revisited: Some preliminary analyses in Japan and the United States. Most psychologists work in research laboratories, hospitals, and other field settings where they study the behavior of humans and animals. Some psychologists are researchers and others are practitioners, but all psychologists use scientific methods to inform their work. Although it is easy to think that everyday situations have commonsense answers, scientific studies have found that people are not always as good at predicting outcomes as they often think they are. The hindsight bias leads us to think that we could have predicted events that we could not actually have predicted. Employing the scientific method allows psychologists to objectively and systematically understand human behavior. Psychologists study behavior at different levels of explanation, ranging from lower biological levels to higher social and cultural levels. The same behaviors can be studied and explained within psychology at different levels of explanation. Some of the most important historical schools of psychology include structuralism, functionalism, behaviorism, and psychodynamic psychology. Cognitive psychology, evolutionary psychology, and social-cultural psychology are some important contemporary approaches. Some of the basic questions asked by psychologists, both historically and currently, include those about the relative roles of nature versus nurture in behavior, free will versus determinism, accuracy versus inaccuracy, and conscious versus unconscious processing. Psychological phenomena are complex, and making predictions about them is difficult because they are multiply determined at different levels of explanation. Research has found that people are frequently unaware of the causes of their own behaviors. There are a variety of available career choices within psychology that provide employment in many different areas of interest. The results of psychological research are relevant to problems such as learning and memory, homelessness, psychological disorders, family instability, and aggressive behavior and violence. Psychological research is used in a range of important areas, from public policy to driver safety. Board of Education, 1954; Fiske, Bersoff, [1] Borgida, Deaux, & Heilman, 1991), as well as court procedure, in the use of lie detectors [2] during criminal trials, for example (Saxe, Dougherty, & Cross, 1985). Psychological research [3] helps us understand how driver behavior affects safety (Fajen & Warren, 2003), which methods of educating children are most effective (Alexander & Winne, 2006; Woolfolk-Hoy, [4] [5] 2005), how to best detect deception (DePaulo et al. For instance, biopsychologists study how nerves conduct impulses from the receptors in the skin to the brain, and cognitive psychologists investigate how different types of studying influence memory for pictures and words. There is no particular reason to examine such things except to acquire a better knowledge of how these processes occur. Applied research is research that investigates issues that have implications for everyday life and provides solutions to everyday problems. Applied research has been conducted to study, among many other things, the most effective methods for reducing depression, the types of advertising campaigns that serve to reduce drug and alcohol abuse, the key predictors of managerial success in business, and the indicators of effective government programs, such as Head Start.

Cross-sectional research This type of research indicates a role for the following beliefs and attitudes: s Perceived social benefits of exercise discount vermox 100mg fast delivery. Research examining the predictors of exercise behaviour consistently suggests that the main factors motivating exercise are the beliefs that it is enjoyable and provides social contact vermox 100mg online. In a cross-sectional study examining the differences in attitude between joggers and non-joggers buy 100mg vermox fast delivery, the non- joggers reported beliefs that exercise required too much discipline, too much time, they did not believe in the positive effects of jogging and reported a lower belief that significant others valued regular jogging (Riddle 1980). In support of this, the non- joggers in the study by Riddle (1980) also reported a lower value on good health than the joggers. Exercisers have also been shown to differ from non-exercisers in their beliefs about the benefits of exercise. For example, a study of older women (aged 60–89 years) indicated that exercisers reported a higher rating for the health value of exercise, reported greater enjoyment of exercise, rated their discomfort from exer- cise as lower and perceived exercise programmes to be more easily available than non-exercisers (Paxton et al. They developed a questionnaire entitled the ‘Temptation to not exercise scale’ which measured two forms of barriers ‘affect’ and ‘competing demands’. The answers include ‘when I am angry’ and ‘when I am satisfied’ to reflect ‘affect’ and ‘when I feel lazy’ and ‘when I am busy’ to reflect competing interests. The authors argue that such temptations are central to understanding exercise uptake and should be used alongside the stages of change model. Prospective research This has examined which factors predict the uptake of exercise. It has often been carried out in the context of the development of exercise programmes and studies of adherence to these programmes. The results indicated that exercise self-efficacy, attitudes to exercise and health knowledge were the best pre- dictors. They concluded that having realistic aims and an understanding of the possible outcomes of a brief exercise programme were predictive of adherence to the programme. To further understand the predictors of exercise adherence, social cognition models have been used. Riddle (1980) examined predictors of exercise using the theory of reasoned action (Fishbein and Ajzen 1975; see Chapter 2) and reported that attitudes to exercise and the normative components of the model predicted intentions to exercise and that these intentions were related to self-reports of behaviour. Research has also used the health belief model (Sonstroem 1988) and models emphasizing exercise self-efficacy (e. Research has also applied the stages of change model to exercise behaviour (see Chapters 2 and 5). This model describes behaviour change in five stages: precontem- plation, contemplation, preparation, action and maintenance (e. DiClemente and Prochaska 1982) and suggests that transitions between changes is facilitated by a cost benefit analysis and by different cognitions. This suggests that encouraging individuals to focus on the pros of exercise may increase the transition from thinking about exercising to actually doing it. The study included a large sample of adults who completed measures by telephone at baseline and then recorded their exercise stage by mail after one year. The results showed that baseline attitude, intention and subjective norm predicted the transition from precontemplation to contemplation, that progression from contemplation to preparation was predicted by intention, perceived behavioural control, attitudes and social support, that progression from preparation to action was predicted by intention and attitude and that transition from action to maintenance was predicted by intention, attitude and social support. This study was an attempt to test directly the role of two social cognition models in predicting exercise behaviour. Background Social cognition models such as the theory of reasoned action and the health belief model have been used to predict and examine health behaviours such as smoking (see Chapter 5), screening (see Chapter 9) and contraception use (see Chapter 8). Norman and Smith (1995) used the theory of planned behaviour (Ajzen 1988) to predict exercise behaviour over a six-month period. Methodology Subjects Eighteen people were asked to complete open-ended questions in order to identify beliefs about exercise that could then be incorporated into a questionnaire. The questionnaire was distributed to 250 subjects and returned by 182 (a response rate of 72. Because the study used a prospective design, a second questionnaire was sent out after six months; 83 individuals returned it completed. Design The study involved a repeated-measures design with questionnaires completed at baseline (time 1) and after six months (time 2). Measures The questionnaire at time 1 asked for the subject’s age and sex and con- tained questions about the following aspects of the theory of planned behaviour, which were rated on a seven-point Likert scale. At time 2, the subjects were asked about their frequency of exercising (as in prior behaviour). This variable was included in order to examine which variables at time 1 predicted future behaviour at time 2. Results The data were analysed using correlation analysis, which examines associations between the different variables (e. Therefore, fre- quent exercisers at time 2 were more likely at time 1 to believe that they would take regular exercise, to hold a strong desire to exercise, to have a positive attitude towards exercise, to perceive pressure from others to exercise, to believe that taking exercise was under their control, and to have exercised frequently in the past. The results from the regression analysis showed that the strongest predictor of future behaviour after six months was prior behaviour.

The Central Council of India’s systems of medicine oversee research insti- tutes order 100 mg vermox otc, which evaluate treatments purchase 100mg vermox with amex. The government is adding 10 traditional medicines into its family welfare programme cheap vermox 100 mg overnight delivery, funded by the World Bank and the Indian government. These medicines are for anaemia, oedema during pregnancy, postpartum problems such as pain, uterine and abdominal com- plications, difficulties with lactation, nutritional deficiencies and childhood diarrhoea. The regulations outline requirements for infrastructure, labour, quality control and authenticity of raw materials, and absence of contamina- tion. Of the 9000 licensed manufacturers of traditional medicines, those who qualify can immediately seek certification for good manufacturing practice. The remainders have 2 years to comply with the regulations and to obtain certification. The government has also established 10 new drug-testing laboratories for Indian systems of medicine and is upgrading existing laboratories to provide high-quality evidence to the licensing authorities of the safety and quality of herbal medicines. Randomised controlled clinical trials of selected prescriptions for Indian systems of medicine have been initiated. These will document the safety and efficacy of the prescriptions and provide the basis for their international licensing as medicines rather than simply as food supplements. Other trials have shown some promise in the treatment of bronchial asthma34,35 and angina. Most of the physicians are based in London but some of them are in areas that have a large Asian community such as Leicester, Birmingham and Bradford. However, many ayurvedic physicians use their education and knowledge in combination with their other healthcare-related licensed credentials. Integration with western medicine The Indian Medicine Central Council was established by a 1970 act to oversee the development of Indian systems of medicine and to ensure good Indian ayurvedic medicine | 215 standards of training and practice. Training for Indian medicine is given in separate colleges, which offer a basic biosciences curriculum followed by training in a traditional system. Recently the Department of Indian Systems of Medicine has expressed concern over the substandard quality of educa- tion in many colleges, which in the name of integration have produced hybrid curricula and graduates, unacceptable to either modern or tradi- tional standards. The department has made it a priority to upgrade training in Indian systems of medicine. Such clinical evaluation is essential because the remedies used in these systems will not be used in allopathic hospitals in a country such as India unless they have shown efficacy in well-controlled trials. However, carrying out randomised, double-blind, multicentre trials with standardised extracts is a slow and laborious process. Furthermore, not all herbal medicines need to undergo this rigorous trial because these preparations are already in use. The situa- tion is still further complicated because the randomised trial may not be totally appropriate for the evaluation of medicines from the traditional systems, where the prakriti (ayurveda system) or mijaj (unani system) of the individual determines the specific therapy to be used. Ayurvedic medicines Herbal drugs constitute a major share of all the officially recognised systems of health in India: ayurveda, yoga, unani, siddha, homoeopathy and natur- opathy. The metals, animals and minerals are purified by individual processes before being used for medicinal purposes. Many forms of ayurvedic medicaments may be identified including the following: • Quath: crushed herbs, used as decoction or tea for internal and external uses • Churna: fine powdered herbs, used as medicine with water or in food for internal and external uses 216 | Traditional medicine • Tail: herbs cooked in edible oil according to rules laid down for internal and external uses • Ghrat/Ghrit: herbs cooked in special butter • Asav/Arista/Sura: a kind of light wine obtained after fermentation of herbs • Arka: a distillation of herbs • Rasausadhi/Kharliya rasayan: herbs mixed with metals, minerals and animal ingredients • Bhasma: ashes • Parpaty: combinations of metals, minerals, animal ingredients and herbs • Kshar/Lavan/Salt/Drava: these are specially prepared medicaments • Medicaments based on guggula (the Indian bdellium tree Commiphora mukul Engl. Containing fruits of black pepper (Piper nigrum), Indian long pepper (Piper longum) and the rhizomes of ginger (Zingiber officinalis), it is a common combination used to stimulate and maintain the digestive and respiratory systems. This it does by reducing kapha and increasing pitta through the rejuvenation of low agni and the burning away of ama (toxins). Indian ayurvedic medicine | 217 • Triphala is a rasayana formula comprising equal parts of three fruits: amalaki (Emblica officinalis), bibhitaki (Terminalia bellirica) and haritaki (Terminalia chebula). When dissolved in the mouth, Triphala can be used to clear congestion and headaches. Other related therapies Unani The word unani derives from the Arabic word for Greece: al-Yunaan and is used to refer to medicine of Graeco-Arabic origin. Unani medicine believes that diseases can be kept at bay by the use of clean and fresh water, breathing clean air and consuming fresh food. Like- wise, a balance should be maintained between the mind and the body so that the metabolic process can take place easily and the body waste evacu- ated. According to unani the human body is composed of seven natural and basic components, called Umoor-e-Tabaiya, that are responsible for maintenance of health. These are similar to those identified in ayurveda: • Elements (arkan) • Temperament (mizaj) • Four humours (akhlaat) – blood, phlegm, yellow bile and black bile • Organs (aaza) • Vital forces or neuro (arwah) • Facultie (quwa) • Functions (afaal). The loss of any one of these basic components or alteration in their physical state could lead to disease, or even death. It is highly essential to consider all these factors so as to reach the correct diagnosis and consequently the correct line of treatment. There are ten specialised branches of unani medicine: • Internal medicine • Gynaecology including obstetrics and paediatrics • Diseases of the head and neck • Toxicology 218 | Traditional medicine Table 7.

In the abdomen buy 100 mg vermox free shipping, the liver is not palpable but the spleen is felt 2 cm under the left costal margin vermox 100 mg discount. The symptoms and investigations are characteristic of primary biliary cirrhosis order 100 mg vermox with amex, an uncommon condition found mainly in middle-aged women. In the liver there is chronic inflammation around the small bile ducts in the portal tracts. Itching occurs because of raised levels of bile salts, and can be helped by the use of a binding agent such as cholestyramine which interferes with their reabsorption. The presence of antimitochondrial antibodies in the blood is typical of primary biliary cirrhosis. The thyroid antibodies reflect the autoimmune thyroid disease which is asso- ciated with other autoantibody-linked conditions such as primary biliary cirrhosis. This should only be carried out after an ultra- sound confirms that there is no obstruction of larger bile ducts. Ultrasound will help to rule out other causes of obstructive jaundice although the clinical picture described here is typical of primary biliary cirrhosis. Dealing with the under- lying cause, wherever possible, is preferable to symptomatic treatment. He has suffered from insulin-dependent diabetes mellitus for 18 years and his diabetic control is poor. He has had recurrent hypoglycaemic episodes, and has been treated in the emergency department on two occasions for this. His general practitioner diagnosed cellulitis and he has received two courses of oral antibiotics. This has made him feel unwell and he has complained to his wife of fatigue, anorexia and feeling thirsty. His treatment is twice-daily insulin, he checks his blood glucose irregu- larly at home. Examination He is clinically dehydrated with reduced skin turgor and poor capillary return. He has an ulcer on the third toe of his right foot and the foot looks red and feels warm. The blood glucose level is not given but the picture is likely to rep- resent hyperglycaemic ketoacidotic coma. The key clinical features on examination are dehydration and hyperventilation, and the triggering problem with the infection in the foot. A persistently high sugar level induced by his infected foot ulcer causes heavy glyco- suria triggering an osmotic diuresis. The extracellular hyperosmolality causes severe cellular dehydration, and loss of water from his brain cells is the cause of his coma. Decreased insulin activity with intracellular glucose deficiency stimulates lipolysis and the production of ketoacids. He has a high anion gap metabolic acidosis due to accumulation of ketoacids (acetoacetate and 3-hydroxybutyrate). Ketones cause a character- istically sickly sweet smell on the breath of patients with diabetic ketoacidosis (about 20 per cent of the population cannot smell the ketones). In older diabetic patients there is often evidence of infection precipitating these metabolic abnormalities, e. The differential diagnosis of coma in diabetics includes non-ketotic hyperglycaemic coma, particularly in elderly diabetics, lactic acidosis especially in patients on metformin, pro- found hypoglycaemia, and non-metabolic causes for coma, e. Salicylate poisoning may cause hyperglycaemia, hyperventilation and coma, but the metabolic picture is usually one of a dominant respiratory alkalosis and mild metabolic acidosis. The aims of management are to correct the massive fluid and electrolyte losses, hypergly- caemia and metabolic acidosis. Rapid fluid replacement with intravenous normal saline and potassium supplements should be started. Regular moni- toring of plasma potassium is essential, as it may fall very rapidly as glucose enters cells. Insulin therapy is given by intravenous infusion adjusted according to blood glucose levels. A nasogastric tube is essential to prevent aspiration of gastric contents, and a bladder catheter to measure urine production. In the longer-term it is important that this patient and his wife are educated about his diabetes and that he has regular access to diabetes services. He has had a cough with daily sputum production for the last 20 years and has become short of breath over the last 3 years. He can no longer carry his shopping back from the supermarket 180 m (200 yards) away. He worked as a warehouseman until he was 65 and has become frustrated by his inability to do what he used to do. He appears to be centrally and peripherally cyanosed and has some pit- ting oedema of his ankles. Treatment with bronchodilators should be pursued looking at the effect of $2-agonists and anticholinergic agents, judging the effect from the patient’s symptoms and exercise toler- ance rather than spirometry.

Imagine an action that you engage in every day and explain how neurons and neurotransmitters might work together to help you engage in that action. Describe the structures and function of the “old brain” and its influence on behavior. Explain the structure of the cerebral cortex (its hemispheres and lobes) and the function of each area of the cortex. If you were someone who understood brain anatomy and were to look at the brain of an animal that you had never seen before, you would nevertheless be able to deduce the likely capacities of the animal. In each animal the brain is layered, and the basic structures of the brain are similar (see Figure 3. The innermost structures of the brain—the parts nearest the spinal cord—are the oldest part of the brain, and these areas carry out the same the functions they did for our distant ancestors. The “old brain‖ regulates basic survival functions, such as breathing, moving, resting, and feeding, and creates our experiences of emotion. Mammals, including humans, have developed further brain layers that provide more advanced functions— for instance, better memory, more sophisticated social interactions, and the ability to experience emotions. Humans have a very large and highly developed outer layer known as the cerebral cortex (see Figure 3. Medical, science, and nature things: Photography and digital imagery by Scott Camazine. The cortex provides humans with excellent memory, outstanding cognitive skills, and the ability to experience complex emotions. The Old Brain: Wired for Survival The brain stem is the oldest and innermost region of the brain. It’s designed to control the most basic functions of life, including breathing, attention, and motor responses (Figure 3. The brain stem begins where the spinal cord enters the skull and forms the medulla, the area of the brain stem that controls heart rate and breathing. In many cases the medulla alone is sufficient to maintain life—animals that have the remainder of their brains above the medulla severed are still able to eat, breathe, and even move. The spherical shape above the medulla is the pons, a structure in the brain stem that helps control the movements of the body, playing a particularly important role in balance and walking. Running through the medulla and the pons is a long, narrow network of neurons known as the reticular formation. The job of the reticular formation is to filter out some of the stimuli that are coming into the brain from the spinal cord and to relay the remainder of the signals to other areas of the brain. The reticular formation also plays important roles in walking, eating, sexual activity, and sleeping. When electrical stimulation is applied to the reticular formation of an animal, it immediately becomes fully awake, and when the reticular formation is severed from the higher brain regions, the animal falls into a deep coma. Above the brain stem are other parts of the old brain that also are involved in the processing of behavior and emotions (see Figure 3. The thalamus is the egg-shaped structure above the brain stem that applies still more filtering to the sensory information that is coming up from the spinal cord and through the reticular formation, and it relays some of these [1] remaining signals to the higher brain levels (Guillery & Sherman, 2002). The thalamus also receives some of the higher brain‘s replies, forwarding them to the medulla and the cerebellum. The cerebellum (literally, ―little brain‖) consists of two wrinkled ovals behind the brain stem. People who have damage to the cerebellum have difficulty walking, keeping their balance, and holding their hands steady. Consuming alcohol influences the cerebellum, which is why people who are drunk have more difficulty walking in a straight line. Whereas the primary function of the brain stem is to regulate the most basic aspects of life, including motor functions, the limbic system is largely responsible for memory and emotions, including our responses to reward and punishment. The limbic system is a brain area, located between the brain stem and the two cerebral hemispheres, that governs emotion and memory. The amygdala consists of two ³almond-shaped‖ clusters (amygdala comes from the Latin word for “almond‖) and is primarily responsible for regulating our perceptions of, and reactions to, aggression and fear. The amygdala has connections to other bodily systems related to fear, including the sympathetic nervous system (which we will see later is important in fear responses), facial responses (which perceive and express emotions), the processing of smells, [3] and the release of neurotransmitters related to stress and aggression (Best, 2009). In one early [4] study, Klüver and Bucy (1939) damaged the amygdala of an aggressive rhesus monkey. They found that the once angry animal immediately became passive and no longer responded to fearful situations with aggressive behavior.
