These give examples of how the ascription of sanity or insanity requires the sort of subtle situation-specific judgments which Miller and Goffman are keen to identify menstruation vs pregnancy discount fertomid 50mg otc. The praying person in Church pregnancy weeks calculator purchase fertomid 50 mg amex, or the mobile phone user menopause uterus changes purchase cheap fertomid line, operate in a context in which others can decode the nature of their speech behaviour menstruation nutrition buy fertomid online now. In a society without psychiatrists breast cancer kd cheap 50 mg fertomid amex, the latter would never arrive but the social judgments would remain (Westermeyer and Kroll 1978) menstrual itching buy fertomid 50mg online. This suggests that identifying residual deviance, and doing something about it, are separate processes. The point made by Coulter and Miller about a general meta-rule implies a global and trans-historical quality about human interaction. However, the application of this meta-rule can vary over time and place; another reason why judgments about madness need to be qualified by social and cultural relativism. For example, cross-cultural studies show how some peculiar actions, such as those linked to hallucinations, may be valued as mystical powers in one culture but dismissed as symptoms of mental illness in another. This shows that the same deviant action may be positively connoted in one context but negatively in another. Thus unintelligibility, as a building block of stereotyping and stigma, is only applicable in those social contexts in which it is disvalued. Nonetheless, there is some empirical validity for the stereotype that psychiatric patients are unintelligible. While these are social judgments made in 30 A sociology of mental health and illness context (not scientific descriptions) they are still practically justified by the meta-rule about intelligibility. Mental health workers and significant others who get to know patients over months and years will describe their predictability (including cues of an imminent period of acute psychosis). Thus single or episodic attributions of unintelligibility do not imply constant unpredictability. The stereotype of the wild and unpredictable lunatic may still exist, but the typical manifestations of mental health problems are more complicated but also more mundane. During the stereotyping of psychiatric patients, an encounter with unintelligible conduct elides quickly and unreasonably into expectations of unpredictability and violence. By contrast, most of the lives of psychotic patients are characterized by low-grade depression or anomie, an experience shaped by their social exclusion. Competence and credibility To summarize some relevant connecting points made earlier, the first element of stereotyping about mental illness is actually quite persuasive for some patients, some of the time. First, only some psychiatric patients (those deemed to be psychotic) speak and act in ways that others cannot readily comprehend. Most patients (those who are depressed or anxious) not only obey the meta-rule of mutual intelligibility, they may actually use their distress as part of this obligation. For example, the agoraphobic patient may argue that they stay in all of the time because they are fearful of leaving their home. They do meet the social obligation of intelligibility and they use their symptoms as a cognitive resource for this purpose. For example, there are patients with circumscribed delusions, who only speak and act oddly when these are discussed or prompted. Madness tends to be episodic, with varying time periods of conformity to norms and evidence of a normal commitment to intelligibility in between crazy episodes. Moreover, social niches may exist in which these deviant qualities are functional or are attributed to social value. To create something original or to think in an original way requires a suspension of conformity and the production of someStigma revisited and lay representations of mental health problems 31 thing which is out of the ordinary. There is some evidence of both forms of transgression overlapping in the same individuals but this is not the same as saying that madness is intrinsically creative. We can neither conclude that all people with a diagnosis of mental illness are creative nor that all creative people are mentally ill. However, the incidence of mental health problems does seem to be higher in creative artists, novelists, poets and musical composers (Chadwick 1997). There is also some evidence that bi-polar disorder has a higher incidence in unusually successful people. This group manifests periods of excessive energy and industriousness and the grandiosity they experience ensures that innovative thought experiments are attempted in practice during manic phases (Jamison 1998). Patients with a diagnosis of obsessive-compulsive disorder are preoccupied with orderliness and rule following to a point that they even construct new rules for themselves to comply with (compulsive rituals). If they are not allowed access to this rule following then they become very distressed. Those with a diagnosis of obsessive compulsive personality disorder are conformist, hygienic, pedantic and moralistic in their outlook. In the nineteenth century, these types of problems were viewed as a form of insanity, whereas now they are framed by psychiatrists as neurotic or personality problems (Berrios 1985). What psychotic and obsessive compulsive problems highlight in different ways is that mental health is defined implicitly by a capacity to conform to role-rule relationships. When patients are mad and they act or speak unintelligibly, then they underconform. Tasks which require close attention to detail and are repetitive are done exceptionally well by obsessional people. The latter are well suited to any occupation involved in counting money carefully or in slowly checking details in a task. Societies which are organized around mechanical rationality would place more of a value in careful rule compliance than those which were more laisser faire. Between 10 to 15 per cent of people with a diagnosis of schizophrenia are described as having religious delusions (Koenig et al. Thus, generally, religious commitment and experience can be a focus of diagnostic interest for psychiatrists. On the other hand, the charismatic seminal leaders of the main world religions could be diagnosed retrospectively as suffering from some form of psychosis. With the 32 A sociology of mental health and illness exception of Judaism, the major religions have placed a positive value on poverty, social isolation and even begging. Siddhartha, who became known as the Buddha, abandoned his comfortable aristocratic existence and went into the forest, isolating himself from the world and putting himself in jeopardy. The prophet Mohammed craved isolation and sought refuge in a cave near Mecca, where he experienced a frequent command hallucination, telling him to cry. However, eventually, their actions yielded not less, but more, social credibility. They also refiect and reinforce a tradition, which pre-dates their existence, in Hinduism of a mendicant tradition of holy men, who put themselves outside of society, with no direct means of support. Holy mendicants, venerated religious leaders and mad patients are separated only by whether their conduct in common is deemed by others to be a product of spiritual choice and duty or of involuntary psychological incompetence. It may seem, on common sense grounds, that mental abnormality intrinsically signals social incompetence. Mental abnormality is not inherently creative but it does seem to be linked, in some people, to enhanced creativity. Also, some symptoms may be linked to enhanced industriousness (in mania) or attention to detail (in obsessionality). Indeed, the various ways in which actions are socially valued or disvalued leads to a highly ambiguous picture, in which those who are deemed to be psychologically normal may be judged to be superior to the abnormal, most of the time, but in some circumstances the reverse may apply. Much depends on a particular social situation placing a value on, and continuing to support, what the identified patient is expressing. The most dramatic example given above is in relation to individual claims of extraordinary spiritual status. The ambiguity highlights again that the same abnormality of thought and action may be praised or pathologized in different social contexts. To summarize the theme of this section, is it fair to stereotype people with mental health problems as being continuously irrational in thought and action and so undeserving of social credibilityfi People manifesting symptoms of mental illness can be highly goal directed, creative, reliable and even inspirational across many generations. Despite this, the powerful stereotype that they should be denied credibility because of their irrationality leads to stigma and discrimination in most modern societies. Stigma revisited and lay representations of mental health problems 33 Does labelling matterfi The above discussion questioned whether or not there was any evidence to provide legitimacy for negative attributions about people with mental health problems. Our conclusion was that little exists about violence and that competence (warranting social credibility) can be affected positively, as well as negatively, by the experience of mental health problems. We emphasized, though, that the question of evidence for lack of intelligibility was more complicated. On the one hand, the absence of intelligibility is a sociological rationale to account for madness in non-medical terms. This rationale is supported by studies of the processes of lay ascriptions about unintelligibility (prior to formal diagnosis by professionals of psychosis). On the other hand, most psychiatric patients are not mad and those that are, are not mad all of the time. If negative stereotyping is unreasonable but still occurs, does any prejudicial action fiowing from it matterfi Put differently, what evidence is there that negative social reactions have any detrimental effect on people with mental health problemsfi When labelling theory first emerged (Scheff 1966) it was faced with an empirical critique and consequently lost its popularity within sociology. Studies emerged which did not seem to confirm the detrimental impact of negative social reactions on people with mental health problems. These studies were complemented by a strong counter-claim to social reaction theory; that labelling actually gave patients the positive opportunity of access to effective pharmacological and psychological treatments to ameliorate their problems. He emphasized that patient behaviour, not the prejudices of others, determines labelling. Link and Phelan (1999) revisited the empirical status of labelling theory and drew attention to a number of studies, which, contra the critique of Gove, clearly demonstrate the negative impact of labelling. These studies indicate that disvalued social statuses, such as prostitution, epilepsy, alcoholism, convict status and drug abuse form a hierarchy of stigma, with mental illness being near to the bottom (Albrecht et al. To confirm this, surveys of the general public show that fear of violence and the need to keep a social distance diminish with increasing contact with people with a psychiatric diagnosis (Alexander and Link 2003). Second, whether or not specialist mental health services have positive or negative effects (a function of their range of quality) independent stigma effects persist from, and are embedded in, social processes in the community. The theory Link and colleagues have developed to account for this second finding, which is supported by their additional experimental investigation of lay views of mental illness, relates not to direct prejudicial action by others but by a shared cultural expectation. The latter is that mental illness will lead to suspicion, loss of credibility and social rejection.

Introduction General practice is at the forefront of healthcare in Australia and in a pivotal position to deliver preventive healthcare. It includes the prevention of illness, the early detection of specifc disease, and the promotion and maintenance of health. Preventive care is also critical in addressing the health disparities faced by disadvantaged and vulnerable population groups. The Red Book is now widely accepted as the main guide to the provision of preventive care in Australian general practice. Purpose the Red Book is designed to provide the general practice team with guidance on opportunistic and proactive preventive care. It provides a comprehensive and concise set of recommendations for patients in general practice with additional information about tailoring advice depending on risk and need. The Red Book provides the evidence and reasons for the effcient and effective use of healthcare resources in general practice. Scope the Red Book covers primary (preventing the initial occurrence of a disorder) and secondary (preventive early detection and intervention) activities. These guidelines focus on preventive activities applicable to substantial portions of the general practice population rather than specifc subgroups. However, there is an emphasis on equity, with recommendations aimed at major disadvantaged groups at higher risk of disease and those who are less likely to receive preventive care. This information can be obtained from the Centers for Disease Control and Prevention at nc. However, the leading causes of death and disability in Australia are preventable or able to be delayed by early treatment and intervention (Figure I. There were 32,919 potentially avoidable deaths in Australia in 2010; 62% were classifed as potentially preventable and 38% as potentially treatable. An Australian review10 concluded that lifestyle interventions could have a large impact on population health. Despite this evidence and wide acceptance of its importance, preventive interventions in general practice remain underused, being the primary reason for the consultation in only seven of every 100 clinical encounters. Much more needs to be done to support and improve proper evidencebased preventive strategies, and to minimise practices that are not benefcial or have been proven to be harmful. Yet there is evidence that some preventive activities are not effective, some are actually harmful. Therefore, it is crucial that evidence clearly demonstrates that benefts outweigh those harms for each preventive activity. Determining whether a preventive activity is benefcial, harmful or of indeterminate effect (ie there is not enough evidence on which to base a decision) requires a consistent, unbiased, evidence-based approach. Cancer screening, in particular, can polarise different sectors of the health profession and broader community. The objective interpretation of evidence, balancing harms and benefts, and considering overdiagnosis and overtreatment is a goal of the Red Book. Screening activities are only recommended where evidence demonstrates that benefts outweigh harms. Chapter 15 provides some guidance on common tests where this is not the case or where the evidence is either unclear or not available. Prevention in the practice population the risk of illness and disease is associated with a range of factors that operate on the individual across the lifecycle. For example, poor nutrition and lack of antenatal care during pregnancy are associated with later risk of chronic diseases in the child. Risk behaviours in childhood may become entrenched, leading to progressive physiological changes that can cause chronic diseases in later life. All these factors are in turn infuenced by the social determinants of health, which operate at the local community and broader societal levels; these are poverty, housing, education and economic development (Figure I. Thus, it is highly desirable for general practice to think beyond the preventive healthcare needs of the individual patient, towards a practice population approach to primary prevention.

Guidelines for preventive activities in general practice 6 9th edition General practice has a practical role to play in addressing these determinants and helping to break the cycle that may exist linking social and economic factors to illness and injury. This requires a systematic approach across the whole practice population, not just for those who seek out or are most receptive to preventive care. This may include auditing medical records to identify those who are missing out, using special strategies to support patients with low literacy, and being proactive in following up patients who are most at risk. It will usually require teamwork within the practice as well as links with other services. General practice also has a broader role in facilitating health improvement for vulnerable and disadvantaged groups in the local community, in association with other services and providers. Measures to improve access to preventive healthcare by Aboriginal and Torres Strait Islander peoples are especially important given their higher burden of disease and the barriers that exist to preventive healthcare. More information is available in the National guide to preventive health assessment for Aboriginal and Torres Strait Islander people, 2nd edn. Screening versus case fnding Many clinicians confuse screening and case-fnding tests. Case fnding is the examination of an individual or group suspected of having, or at risk of, the condition. Case fnding is a targeted approach to identifying conditions in select patients who may already have symptoms. If a clinician initiates screening in asymptomatic individuals, there needs to be conclusive evidence that the procedure can positively affect the natural history of the disorder. Moreover, the risks of screening must be carefully considered as the patient has not asked the health professional for assistance. This situation is somewhat different from case fnding, where the patient has presented with a particular problem or has asked for some level of assistance. It could be argued that there is at least some implied exposure to risk (eg performing colonoscopy to investigate abdominal pain). Proactive recall of patients for screening is warranted for high-risk groups, those who may have diffculty accessing services and for conditions where population coverage has been identifed by the government as a public health priority. There is evidence that these assessments improve the likelihood of preventive care being received. Patient education and health literacy Impact of patient education Patient education and counselling contribute to behaviour change for the primary prevention of disease. The use of behavioural techniques, especially for self-monitoring, is recommended, as is the use of personal communication and written or other audiovisual materials. In general practice, it may take at least six to eight sessions to discuss and see changes to diet, physical activity or weight loss. This will often require referral, which should be followed up by the general practice. As the patient plays a large role in making this happen, it is useful to facilitate more active inclusion of patients in their care. Approaches to patient education Patients need to develop their own understanding of the problem and what can be done about it. For simple behavioural changes, such as having a cervical cancer screening test, patients weigh up the perceived benefts and costs. Some health education may require more complex actions over a period of time, such as changing diet, stopping smoking or increasing physical activity. Motivational interviewing is a counselling philosophy that values patient autonomy and mutual respect, and the use of open-ended questions, affrmations, refection and summarising. As well as having more chronic health conditions, and more health behaviours leading to increased risk, there may be a lack of local support and infrastructure to improve the situation. There are specifc issues for Aboriginal and Torres Strait Islander peoples, where an ongoing history of colonisation, dispossession and racism interact with a lack of economic opportunity. The National guide to a preventive health assessment for Aboriginal and Torres Strait Islander people, 2nd edn50 provides extensive detail on specifc preventive care issues facing Aboriginal and Torres Strait Islander peoples, and the health equity material canvassed here should be read in conjunction with those guidelines. They provide much more in-depth and important guidance on preventive healthcare strategies that are recommended for practitioners working with Aboriginal and Torres Strait Islander peoples and communities. Guidelines for preventive activities in general practice 10 9th edition Supporting patient education and health literacy in disadvantaged groups What are the key equity issues and who is at riskfi Health literacy is a key factor in how patient education leads to patient empowerment. It allows individuals to access, understand and use information to negotiate the health system and support self-management. This is particularly important in working with Aboriginal and Torres Strait Islander communities. The Red Book maintains developmental rigour, editorial independence, and relevance and applicability to general practice. Recommendations the recommendations in the Red Book are based on current, evidence-based guidelines for preventive activities. However, particular references may relate only to part of the recommendation (eg only relating to one of the high-risk groups listed), and other references in the section may have been considered in formulating the overall recommendation. These recommendations are based on the best available information at the time of writing (May 2015 to May 2016). How to use the Red Book the Red Book is designed to be used in a number of ways, all of which can be useful in day-to-day general practice. Organisational detail the information in the Red Book is organised into three levels. The frst level is the lifecycle chart, which highlights when preventive activities should be performed and the optimum frequency for each activity. Simply check the column under a particular age group to see what activities should be considered for the patient. The preventive activities that are recommended for everyone within a particular age range, and for which there is sound research evidence, are shaded in red. Activities to be performed only in patients with risk factors or where the evidence is not as strong are shaded in light red or pink. A copy of this chart can be downloaded and attached to the patient record as a systematic reminder for preventive activities. The second level is more detailed and presents a summary of recommendations in addition to tables that identify what preventive care should be provided for particular groups in the population.

We have been able to include on this occasion further colour photographs rather than line drawings which I hope will remain in the memory better and serve as reminders to the readers of the conditions that can occur within the upper aerodigestive tract. It is interesting in revising this little book every few years how much there is to change in fairly subtle ways as the specialty develops and technology improves. The trend in educational circles in the early part of the 21st century seems to be that students should learn less and less factual knowledge and there is far more concern with process and in a spirit of concordance with this (though not entire agreement), I have reduced the text of some of the chapters considerably and omitted quite a lot of details, particularly where it relates to surgical procedures. Acknowledgements I am pleased to acknowledge the invaluable help of the editorial and production departments of Blackwell Publishing who have encouraged the production of this new edition of Lecture Notes in Diseases of the Ear,Nose and Throat, and in particular to Fiona Goodgame and Alice Emmott. I am grateful to my clinical colleagues for advice willingly given and for help with the illustrations. I am indebted particularly to Mark Yardley, Tim Woolford, Charles Romanowski and Tim Hodgson. Without the skill and cooperation of the Department of Medical Illustration at the Royal Hallamshire Hospital, I would have had few images to include in this little book. Bull January 2002 vii Preface to the First Edition this book is intended for the undergraduate medical student and the house officer. It is hoped that, though elementary, it will also prove of use to the general practitioner. He is not asked to perform complex aural operations, or even to be acquainted with their details, but he is expected to appreciate the significance of headache supervening in otitis media, to treat epitaxis, and to know the indications for tonsillectomy. Emphasis has therefore been laid on conditions that are important either because they are common or because they call for investigation or early treatment. Time spent in this occupation will certainly not be wasted,for the questions refer,in every case, to the fundamentals of the specialty. At the medial end of the meatus there is the antero-inferior recess, in which wax, debris or foreign bodies may lodge. The normal appearance of the membrane is pearly and opaque, with a well-defined light refiex due to its concave shape. The major reason for having an air-containing middle ear is to reduce the acoustic impedance that would be caused if a sound wave in air were to be applied directly to the cochlear fiuids. Without this impedance matching, 99% of the sound energy would simply be refiected at an air/fiuid interface. The tube is more 1 2 Chapter 1: the Ear: Some Applied Anatomy Pars flaccida Handle of malleus Light reflex Pars tensa Fig. The extent of pneumatization is very variable and is usually reduced in chronic middleear disease. Modern auriscopes have distal illumination via a fibre-optic cone giving a bright, even light. A common error in examination of the tympanic membrane is to use too small a speculum; the largest that can be inserted easily should be used. If you cannot get a good view,either the speculum is the wrong size or the angulation is wrong. Such practice will lead to the recognition of subtle abnormalities as well as the more obvious ones. A more formal assessment is then made by asking the patient to repeat words spoken by the examiner at different intensities and distances in each ear in turn. If profound unilateral deafness is suspected, the good ear should be masked with a Barany noise box and the deaf ear tested by shouting into it. The limitations of voice and whisper tests must be borne in mind; they are approximations but with practice can be a good guide to the level of hearing and will confirm the audiometric findings. Mixed deafness Mixed deafness is the term used to describe a combination of conductive and sensorineural deafness in the same ear. The base of a vibrating tuning fork is held on the vertex of the head and the patient is asked whether the sound is heard centrally or is referred to one or other ear. The audiometer is an instrument that generates pure tone signals ranging from 125 to 12000Hz (12kHz) at variable intensities. Signals of increasing intensity at each frequency are fed to the patient, who indicates when the test tone can be heard. The threshold of hearing at each frequency is charted in the form of an audiogram (Figs 3. A recorded word list is supplied to the patient through the audiometer at increasing loudness levels, and the score is plotted on a graph. In some disorders, the intelligibility of speech may fall off above a certain intensity level. Above a critical threshold, sounds are suddenly perceived as having become excessively loud. A pure tone signal of known intensity is fed into the external auditory canal and a microphone in the ear probe measures refiected sound levels. By making the computer look at different time windows, responses at various sites in the auditory pathway can be investigated. As the response travels from the cochlea to the auditory cortex, the latency increases from about 1-4 to 300ms. The 100 bone conduction is normal 110 but the air conduction 120 curve is impaired. Electric response audiometry has the unique advantage of being an objective measure of hearing requiring no cooperation from the subject. It is of value in assessing hearing thresholds in babies and small children and in cases of dispute such as litigation for industrial deafness. This can be detected and recorded and has been used as a screening test of hearing in newborn babies. It is now in routine clinical use in testing those babies who are particularly at risk of hearing problems, such as premature or hypoxic neonates, and is likely to play a part in universal screening for hearing loss. The distinction is easily made by tuning fork tests, which should never be omitted. Always try to make a diagnosis of the cause of deafness and start by deciding whether it is conductive or sensorineural. The deaf child Early diagnosis of deafness in the infant is essential if irretrievable developmental delay is to be avoided. The health visitor should screen all babies at about 8 months of age and those failing a routine test must be referred to a specialist audiological centre without delay for more thorough investigation. Sudden sensorineural deafness Sudden sensorineural deafness is an otological emergency and should be treated as seriously as would be sudden blindness. Immediate admission to hospital should be arranged, as delay may mean permanent deafness. Sudden deafness may be unilateral or bilateral and most cases are regarded as being viral or vascular in origin. Investigation may fail to show a cause and treatment is usually with low-molecular-weight dextran, steroids and inhaled carbon dioxide. Bilateral profound deafness, especially if of sudden onset, is a devastating blow and for this reason various organizations exist to give advice and support. In its advanced stage, there is raised intracranial pressure and brain stem displacement. Unilateral sensorineural deafness should always be investigated to exclude a neuroma. Hearing aids In cochlear forms of sensorineural deafness, loudness recruitment is often a marked feature. This results in an intolerance of noise above a certain threshold, and makes the provision of amplification very difficult. If the mould does not fit well, oscillatory feedback will occur and the patient will not wear the aid. The current generation of hearing aids are digital, allowing more refinement in the sound processing and more control of the aid. A titanium screw is threaded into the temporal bone and allowed to fuse to the bone (osseo-integration). A transcutaneous abutment then allows the attachment of a special hearing aid that transmits sound directly by bone conduction to the cochlea. The apparatus consists of a microphone, an electronic sound processor and a single or multichannel electrode implanted into the cochlea. Results, particularly with an intracochlear multichannel device, can be spectacular, with some patients able to converse easily. Most patients obtain a significant improvement in their ability to communicate and implantation has been extended for use in children. Lip-reading Instruction in lip-reading is carried out much better while usable hearing persists and should always be advised to those at risk of total or profound deafness. Electronic aids for the deaf Amplifying telephones are easily available to the deaf and telephone companies usually provide willing advice. Many modern hearing aids are fitted with a loop inductance system to make the use of telephones easier. Various computerized voice analysers that give a rapid visual display are also available, but these require the services of a skilled operator and are still in the developmental phase. Automatic voice recognition machines may take over this role in the foreseeable future. The underlying deformity is the absence of the antehelical fold in the auricular cartilage. Affiicted children are often teased mercilessly and surgical correction can be carried out after the age of four.
