A doctor who publishes his own textbooks can earn many times what he would be paid in royalties by a publishing house. More important than this, however, is the fact that a doctor who writes and publishes wants his texts to be read by as many colleagues, students and patients as possible. Te best way to achieve this is through free parallel publication of these texts on the internet. Free Medical Information describes how to produce a successful medical textbook: from defining the project, selecting the co- authors and fixing the deadlines to building the website, printing, marketing, distributing, and negotiating with the sponsors. A book for future publishers and authors, for doctors and students Free – for all those who would like to know how medical textbooks are produced today.

Emma Raderschadt Cover: Attilio Baghino Foreword Today, doctors can be publishers – computer technology and the internet make it possible, and book projects are tempting in terms of money. A doctor who publishes his own textbooks can earn many times what he would be paid in royalties by a publishing house. More important than this, however, is the fact that a doctor who writes and publishes wants his texts to be read by as many colleagues, students and patients as possible. The best way to achieve this is through free parallel publication of these texts on the internet. The experience of the last few years has shown that a medical textbook which is accessible free of charge on the internet is read ten times as often as the book in print. How, asks the observer, are you going to sell a book in print if it is accessible on the internet and thus available to everyone? The answer is as simple as it is surprising: by increasing the share of the market. The freely available internet version is the best possible publicity for a book, and rival texts which have only been published in print have no chance in the long run when up against the combination of parallel publication, book + internet. This book shows how doctors can produce and market their own books. Since 2003, our HIV textbook has been available free of charge on the internet and is updated yearly (www. Better still: as soon as the individual chapters have been revised they are published on the internet – months before they appear in print. Similar projects are now being developed for other themes, and a new age awaits beyond the horizon. The most important subjects can be covered in 100 textbooks. A hundred books – 50,000 pages – give answers to 99% of the questions which crop up in our daily routine as doctors. We would like the most important medical fields to be covered in freely available textbooks on the internet by the year 2010.

Blockade of the nigrostriatal pathway by the antipsychotics is unintended and results in movement side-effects 2mg aceon. To rebalance the extrapyramidal system buy discount aceon 2mg line, an acetylcholine blocker may be administered purchase 2 mg aceon. In the healthy individual, tonic release of dopamine into this system inhibits the release of prolactin. Unintentional disruption of this system leads to elevation of serum prolactin and the side-effects of gynecomastia, galactorrhea and sexual dysfunction. However, particular psychiatric medications are often used for disorders outside their “classification”. For example, the selective serotonin reuptake inhibitors (SSRIs) which were initially marketed as antidepressants, have become the drugs of first choice in most anxiety disorders and OCD, and the tricyclic antidepressants (TCAs) are used in bed-wetting (enuresis) because their anticholinergic “side-effects” cause tightening of the bladder neck. The so-called “side-effects” of drugs may sometimes be useful, for example, people with major depressive episodes who have difficulty with sleep may benefit from an antidepressant with sedating “side-effects” being given at night. Interestingly, LSD (lysergic acid diethylamide) and Ecstasy, now considered dangerous and illegal, have both been considered as potential psychiatric treatments. They are the mainstay of the treatment of schizophrenia and will be discussed below in that context. However, they are also the mainstay of the management of delusional disorder, psychosis which occurs in dementia, they have a place in the management of delirium, and they must be added to antidepressants for the successful management of psychotic depression. The antipsychotics have a central place in the management of acute mania (even in the absence of delusions and hallucinations). Olanzapine, aripiprazole and others have gained acceptance as mood stabilizers (prophylactic Pridmore S. Quetiapine has been approved by the FDA (USA) as a treatment for bipolar depression (Dando & Keating, 2006). In rare cases antipsychotics are used in the management of insomnia and anxiety (Carson et al, 2004), but this is not recommended and is best left to experts. THE TYPICAL ANTIPSYCHOTICS The typical antipsychotic drugs were the first effective antipsychotics. Chlorpromazine was the first, being described by French doctors in 1952. Others followed, including: haloperidol, fluphenazine and thiothixene. There is a straight line relationship between the affinity of the typical antipsychotics for the dopamine D2 receptor and the therapeutic dose of these agents used in acute schizophrenia. This is consistent with the dopamine hypothesis of schizophrenia Illustration. This straight line relationship supports the dopamine hypothesis of schizophrenia. Side-effects of typical antipsychotics The extrapyramidal system (EPS) - the EPS is not a side-effect of antipsychotics, but needs to be mentioned before certain side effects. The EPS is a component of the motor system composed of dopamine (DA) and acetylcholine (Ach) neurons which enjoy a reciprocal/balanced relationship. In some individuals when DA receptors are blocked, the balance in the system is disrupted, leading to side-effects. This is particularly a feature of the older, First Generation Antipsychotics (FGAs). These can appear on the first day of treatment and can take various forms of involuntary muscle spasm, particularly involving of the jaw, tongue, neck and eyes. A dramatic form is oculogyric crisis – in which the neck arches back and the eyes roll upward. Balance has been disturbed resulting in muscle spasm, and can be restored by acute treatment with oral or intramuscular injection of an anti-Ach – such as benztropine (2 mg). Medium-term neurological side-effects are also due to D2 blockade in the EPS. Akathisia usually occurs in the first few day of treatment and involves either a mental and/or motor restlessness. Mental restlessness presents as increasing distress and agitation. Motor restlessness usually affects the lower limbs, with shifting from one foot to the other while standing and constant crossing and uncrossing of the legs while sitting. Useful steps include lowering the dose of the antipsychotic (if possible), adding diazepam or propranolol, or adding an anticholinergic (none of these is dramatically effective). Parkinsonism usually occurs some days or weeks after the commencement of treatment. There is a mask-like face, rigidity of limbs, bradykinesia, and loss of upper limb-swing while walking. The best management is reduction in dose of the antipsychotic (if possible) and the addition of an anticholinergic agent. Chronic neurological side-effects (late EPS effects) usually occur after months or years of continuous D2 blockade. Tardive dyskinesia (TD) manifests as continuous choreoathetoid movements of the mouth and tongue, frequently with lip-smacking, and may also involve the head, neck and trunk. Late EPS effects may continue after cessation of the typical antipsychotic. Neuroleptic malignant syndrome (NMS) is probably due to disruption of dopaminergic function, but the mechanism is not understood. Untreated, the mortality rate is 20%, and immediate medical attention is mandatory. The symptoms include muscle rigidity, hyperthermia, autonomic instability and fluctuating consciousness. Renal failure secondary to rhabdomyolysis is a major complication and the cause of mortality. Neuroendocrine effects result from blockade of dopamine transmission in the infundibular tract.

2 mg aceon with amex

When an insulted peripheral nerve dies generic aceon 8mg online, there is a loss of afferent input purchase 4mg aceon amex, leading to “deafferent hypersensitivity” in second order cells 2mg aceon visa. Also, when an insulted peripheral nerve dies, reorganization in the dorsal horn may lead to second order neurons linking up with the “wrong” peripheral nerves, such that innocuous peripheral sensations are presented to the brain as pain input. This greatly increases the amount of pain information reaching the brain, and a gentle breeze on the skin (for example) may cause pain. In addition, reorganization may involve the sympathetic nervous system, and activity in this system (e. Dysesthesia and allodynia are clinical signs which are pathognomonic of neuropathic pain and have both peripheral and central sensitization components. Dysesthesia is abnormal spontaneous sensations such a sudden “electric shocks” and “pins and needles”. Allodynia is abnormal sensation in response to external stimuli, such as extreme pain in response to innocuous touch (e. Clearly, rheumatoid arthritis (for example) is associated with chronic pain, but if this can be controlled in the rheumatology clinic and the patient lives a satisfying life, the term has less relevance. The term chronic pain is used particularly following trauma or degeneration, and pain continues beyond the normal healing time, e. The term chronic pain is also used for chronic back pain, especially chronic back pain with minimal imaging findings. The characteristic of chronic pain is “suffering”, by which is meant, there is not only pain, but a pervasive experience of distress. There is a loss of the ability to work or perform normal daily functions. There is inactivity, loss of social life and energy, low mood and high anxiety. There may be difficulty with concentration and reduced ability to solve problems. Nociceptive and neuropathic pain frequently coexist. Even when an injury/degeneration has not damaged peripheral nerves, the pain experience may alter the central nervous system. This has led to the increasingly endorsed theory that “chronic pain is a disease of the brain” (Borsook et al, 2010). Transition from acute to chronic pain is not well understood, but includes brain changes [next section]. The importance of the interaction of the nervous and immune systems in this process is now receiving attention (Mifflin & Kerr, 2013). Brian changes in chronic pain Brain changes associated with chronic pain have only been identified in recent times, and are a currently being excitedly explored. They may occur in the absence of obvious peripheral nerve damage, but are nevertheless termed “neuropathic” changes. Loss of gray and white matter and alterations of brain function have been described. The nature of the loss of gray matter remains uncertain; it may represent loss or atrophy of nerve cells, dendrites, synapses, or glia. Grachev et al (2001) suggested “neuronal loss and degeneration”, however, Rodriguez-Raecke et al (2009) found that much of the cerebral gray matter lost in association with the chronic pain of OA hip was restored after successful hip replacement, suggesting that actual loss (death) of cells may not be the explanation. As described above, acute pain is associated with activity in SI, SII, ACC, IC, Th and PFC. However, chronic pain, gray matter loss and increased activity is most commonly found in the PFC, suggesting a greater role for this region (Akparian et al, 2005). A host of other studies support this finding, and are listed in the next section. Thus, acute (experimental) and chronic pain are underpinned by overlapping, but slightly different, brain maps. The prominent activation of the PFC (and projection areas) and the demonstrated a disruption of the functional connectivity between brain regions (Baliki et al 2008) are the probable explanation for chronic pain patients experiencing, in addition to pain, depression and anxiety, sleep disturbance and decision-making (cognitive) abnormalities. Increased activity is also frequently demonstrated in the PAG (Gwilym et al, 2009) and the cerebellum. The PAG is an important component of the descending pain inhibition system, but the role of the cerebellum in chronic pain is unknown. There are similarities in the brain maps of individuals with the same chronic pain condition. However, overlap between the maps of different disorders, makes uncertain whether a distinct brain map will be discovered for each chronic pain disorder. In irritable bowel syndrome (IBS), PET demonstrated pain associated with rectal distention is associated with increased activity in the frontopolar region (Brodmann area 10; parts of the superior and middle frontal gyrus) and no activity in ACC. The reverse is the case in healthy individuals (Silverman et al, 1997). In IBS, MRI demonstrated gray matter density changes (increases and decreases) in regions associated with depression, anxiety and cognition (Seminowicz et al, 2010). In chronic back pain (CBP), magnetoencephalogam (MEG; which measures electrical activity) shows that the area of SI devoted to the back is enlarged and shifted medially (Flor et al, 1997; indicating “cortical reorganization”). In CBP, magnetic resonance spectroscopy (MRS; which quantifies chemical levels) shows that the N-acetyl aspartate (NAA) and glucose levels are elevated in the dorsolateral PFC, while glucose is reduced in Th (Grachev et al, 2000). MRS findings are independent of the cognitive level at the time, thus these chemical changes reflect long-term plastic modifications. In CBP, MRI demonstrates a 5-11% reduction in neocortical gray matter volume (Apkarian et al, 2004). This is equivalent to 10-20 years of normal aging, and represents 1. In CBP, fMRI demonstrates a disruption of the functional connectivity between brain regions (Baliki et al 2008). In OA hip (in patients with increased sensitivity and referred pain), fMRI demonstrates increased activity in ACC, DLPFC and PAG (among others, Gwilym et al, 2009). In OA hip, MRI shows reduced gray matter density in ACC, DLPFC, IC, and brain stem (along with some other areas).

The edges and even the base of the lesion were scarred and indurated discount 8mg aceon with visa. He burnt the dorsum of his right hand and there was muscle tissue loss from the extensors of his right forearm discount aceon 8mg otc. There were less obvious (in these photographs) scars on the upper chest aceon 4 mg on-line. In the past he had swallowed razor blades, which had perforated his bowel, leading to abdominal surgery. This man then repeatedly removed the stiches and recut his abdominal scar leading to a large incisional hernia. Histrionic Pervasive pattern of excessive emotionality and attention seeking. There must be at least 5 of the following:  Is uncomfortable in situations in which he/she is not the centre of attention  Inappropriate sexually seductive or provocative behaviour  Displays rapidly shifting and shallow expressions of emotions  Consistently uses physical appearance to draw attention to self  Has a style of speech that is excessively impressionistic and lacking in detail  Shows self-dramatization, theatricality, exaggerated expressions of emotion  Is suggestible (easily influenced by others or circumstances)  Considers relationships to be more intimate that they actually are Prevalence rates are 2-3% in the general population, and 10-15% in psychiatric inpatient populations. A genetic link between histrionic and antisocial personality disorder, and alcoholism, has been suggested. Narcissistic Pervasive pattern of grandiosity (in fantasy or behaviour), need for admiration, and lack of empathy. There must be at least 5 of the following:  Has a grandiose sense of self-importance (eg, exaggerates achievements and talents, expects to be recognized as superior without achievements)  Is preoccupied with fantasies of unlimited success, power, brilliance, beauty, or ideal love  Believes he/she is “special” and unique and can only be understood by, or should associate with , other special or high-status people (or institutions)  Requires excessive admiration  Has a sense of entitlement, i. The leading story of a regional newspaper told that a state branch of the Royal Society for the Protection and Care of Animals had lost millions of dollars in donations due, in part, to the “repeated lying” of the CEO. In his response the CEO wrote, “…I am a very moral and ethical person and feel incredible shame that this happened…I admit freely the lies I told…” It may be difficult to obtain a complete understanding of events from newspaper reports. Here, the reader finds it difficult to comprehend how a person in a position of responsibility could admit to telling “lies”, but at the same time maintain that, “I am a very moral and ethical person”. One explanation would be that the individual is narcissistic and thinks well of himself, in spite of evidence to of immoral actions. Cluster C – Individuals appear anxious or fearful Avoidant Pervasive pattern of social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation. There must be at least 4 of the following:  Avoids occupational activities that involve significant interpersonal contact, because of fears of criticism, disapproval, or rejection  Is unwilling to get involved with people unless certain of being liked  Shows restraint within intimate relationships because of the fear of being shamed or ridiculed  Is preoccupied with being criticized or rejected in social situations  Is inhibited in new interpersonal situations because of feelings of inadequacy  Views self as socially inept, personally unappealing, or inferior to others  Is unusually reluctant to take personal risks or to engage in any new activities because they may prove embarrassing Prevalence of 0. There must be at least 5 of the following:  Has difficulty making everyday decisions without an excessive amount of advice and reassurance from others  Needs others to assume responsibility for most major areas of his/her life  Has difficulty expressing disagreement with others because of fear of loss of support or approval  Lack of initiative  Goes to excessive lengths to obtain nurturance and support form others  Feels uncomfortable or helpless when alone because of exaggerated fears of being unable to care for him/her self  Urgently seeks another relationship as a source of care and support when a close relationship ends  Unrealistically preoccupied with fears of being left to take care of him/herself May be the most common personality disorder. Obsessive-compulsive Pervasive pattern of preoccupation with orderliness, perfectionism, and mental and interpersonal control, at the expense of flexibility, openness, and efficiency. There must be at least 4 of the following:  Preoccupation with details, rules, lists, order, organization or schedules to the extent that the major point of the activity is lost  Perfectionism that interferes with task completion  Over conscientiousness, scrupulousness, and inflexible about matters of morality, ethics, or values. There is an increased risk of major depressive disorder and anxiety disorder, but for evidence for increased risk of OCD has not been established. Alternative DSM-5 Model for Personality Disorders The DSM-5 authors are in favour of moving to a dimensional approach. They present the categorical model (and diagnoses) which are well established, but also introduce The Alternative DSM-5 Model for Personality Disorder, with the aim of addressing some shortcomings of the categorical approach, and with the suggestion that this may be the way of the future. This model contends that personality disorders are characterized by impairments in personality functioning and personality traits. Identity: Experience of oneself as unique, with clear boundaries between self and others, stability of self-esteem and accuracy of self- appraisal; capacity for and ability to regulate, a range of emotional experiences. Self-direction: Pursuit of coherent and meaningful short-term and life goals; utilization of constructive and prosocial internal standards of behaviour; ability to self-reflect productively. Intimacy: Depth and duration of connection with others; desire and capacity for closeness; mutuality of regard reflected in interpersonal behaviour. Five Pathological Personality traits have also been listed in DSM-5 1. Psychoticism And each of these can exist at five levels. Neuroimaging in personality disorder Neuroimaging in personality disorders is a relatively new field. It would not be surprizing if the brains of people who thought and behaved differently to the average person had somewhat different brain operations. It needs to be said that personality and personality disorder is subtle stuff – and modern neuroimaging techniques generate vast amounts of information, and neuroimaging teams do not follow a standard protocol. Accordingly, it is most unlikely that neuroimaging will produce anything of clinical significance in the foreseeable future – the following details are provided to give a sense of the activity in this research area. Structural studies have reported decreased prefrontal grey matter, decreased posterior hippocampal volume and increased callosal white matter, but to this point, these studies have not been confirmed. Functional studies suggest reduced perfusion and metabolism in the frontal and temporal lobes. Two studies are of interest - Kiehl et al (2001) used fMRI and reported that when criminal psychopaths were dealing with emotional material (words), there was increased activity in the frontotemporal cortex. This was taken as evidence that psychopaths needed to exert additional effort to deal with emotional material. The same group (Kiehl et al, 2004) then reported that criminals failed to show a difference in activation of the right anterior temporal gyrus when processing abstract and concrete words. This was consistent with the proposition that psychopathy is associated with dysfunction of the right hemisphere during the processing of abstract material. The authors speculated that complex social emotions such as love, empathy and guilt may call for abstract functioning, and that abstract processing deficits based in the right temporal lobe, may be a fundamental abnormality in psychopathy. Blair (2003), however, argues that the neural basis of psychopathy is malfunction of the amygdala and connections to the orbitofrontal cortex. Borderline personality disorder Imaging studies demonstrate differences between people with BPD and healthy controls. Kuhlmann et al (2012) found, in women with BPD, reduced grey matter in the hippocampus and increased grey matter in the hypothalamus. Functional abnormalities have been detailed (Krause-Utz et al, 2014). Magnetic Resonance Spectroscopy (MRS) reveals N-acetyl-aspartate (NAA) concentrations are reduced in the dorsolateral prefrontal cortex, suggesting a lower density of neurons and disturbed neuronal metabolism. These anatomical studies are consistent with functional imaging findings. Positron emission (PET) studies generally demonstrate low metabolism in regions of the frontal cortex, basal ganglia, thalamus, hippocampus and posterior cingulate.
