TIMOTHY WALSH Anorexia nervosa (AN) and bulimia nervosa (BN) are disor- relating weight and shape to self-concept are shared by pa- ders characterized by aberrant patterns of feeding behavior tients with both of these syndromes, and that transitions and weight regulation, and disturbances in attitudes toward between these syndromes occur in many, it has been argued weight and shape and the perception of body shape. In AN, (3) that AN and BN share at least some risk and liability there is an inexplicable fear of weight gain and unrelenting factors in common. BN usually emerges after a period of dieting, and multiply influenced by developmental, social, and bio- which may or may not have been associated with weight logical processes (4,5); however, the exact nature of these loss. Either self-induced vomiting, or some other means of interactive processes remains incompletely understood. Cer- inappropriate compensation for the excess of food ingested tainly, cultural attitudes toward standards of physical attrac- follows binge eating. The majority of people with BN have tiveness have relevance to the psychopathology of eating irregular feeding patterns and satiety may be impaired. Al- disorders (EDs), but it is unlikely that cultural influences though current AN is an exclusion for the diagnosis of BN, in pathogenesis are prominent. Dieting behavior and the some 25% to 30% of individuals with BN presenting to drive toward thinness are quite commonplace in industrial- treatment centers have a prior history of AN; however, all ized countries throughout the world, yet AN and BN affect BN subjects have pathologic concern with weight and only an estimated. Common to individuals with AN or BN are low self- tively, of women in the general population. Also, both sion of appetite, but rather exhibit a volitional and often syndromes (particularly AN) have a relatively stereotypic an ego syntonic resistance to feeding drives, eventually be- clinical presentation, sex distribution, and age of onset. This coming preoccupied with food and eating rituals to the supports the possibility that there are significant biologic point of obsession. Similarly, BN may not be associated vulnerabilities to developing an ED. Loss of control with overeating usually occurs intermittently Variations in feeding behavior have been used to subdivide and typically only some time after the onset of dieting be- individuals with AN into two meaningful diagnostic havior. Episodes of binge eating ultimately develop in a subgroups that differ in other psychopathologic characteris- significant proportion of people with AN (1), whereas 5% tics (6,7). In the restricting subtype of AN, subnormal body of those with BN eventually develop AN (2). Considering weight and an ongoing malnourished state are maintained that restrained eating behavior and dysfunctional cognitions by unremitting food avoidance; in the binge eating/purging subtype of AN, there is comparable weight loss and malnu- trition, yet the course of illness is marked by episodes of Walter H.

People who have an ED often have a variety of symptoms Individuals with BN remain at normal body weight, al- aside from pathologic eating behaviors.

The DSM-IV has specified a distinction feeding behavior or malnutrition is a major methodologic within this group between those individuals with BN who issue in the study of EDs. It is impractical to study EDs engage in self-induced vomiting or abuse of laxatives, di- prospectively because of their low incidence, early age of uretics, or enemas (purging type), and those who exhibit onset, and difficulty of premorbidly identifying those who other forms of compensatory action such as fasting or exer- will develop an ED.

Experts draw attention to the central role of deception – but buy ceftin 250 mg visa, acknowledge that deception is common in human interaction (Bass and Halligan generic ceftin 250 mg otc, 2014). Falsification of physical or psychological signs or symptoms, or induction of injury or disease, associated with identified deception. Individual presents him/herself to others as ill, impaired, or injured. Deceptive behaviour is evident even in the absence of obvious external rewards. Factitious disorder was first introduced as a diagnostic category in 1980 (DSM-III). It is characterized by physical or psychological symptoms that are intentionally produced or feigned in order to assume the sick role (a role in which one gets many advantages, including care, consideration and support from professional people, as well as being relieved of the responsibility to go to work and caring for others). People with factitious disorder are accepted as legitimate patients; it is argued that they have emotional needs (as we all do), but lack understanding of their own emotional life, and the ability to satisfy their emotional needs in more appropriate/adaptive ways.

Typically, they do not travel to present at different treatment centres. Often have a history of emotional deprivation and current sexual and/or relationship problems. The term “factitious nurses” has been applied (Kanaan & Wessely, 2010). He frequently travels from one treatment centre to another, often in different cities. There are usually also self-aggrandizing lies (pseudologia fantastica) – which led to the condition being named for Baron Munchausen. This is a distinct problem and will be dealt with under a separate heading. Factitious disorder most commonly presents with physical complaints. The prevalence is difficult to estimate, however, estimates include that 0. The prevalence probably varies with speciality, with up to 15% of presentations to neurologists and dermatologists involving factitious symptoms (McCullumsmith & Ford, 2011). The prevalence of factitious disorder among psychiatric patients is unclear. Catalina et al (2008) to identify factitious behaviour in psychiatric inpatients - developed an 8 criteria suspicion of factitious disorder test - the identification threshold - 3 positive criteria responses. Using this tool they found 8% of psychiatric inpatients demonstrated factitious behaviour. Inconsistent symptoms (with respect to presenting syndrome) 3. Disappearance of symptoms immediately after admission 5. Appearance of symptoms similar to those of other patients 7. Claimed background of non-verified physical or emotional disorders Pridmore S.

This may be because psychiatry is a low status speciality or does not provide the preferred type of care. Other factors may be that being referred to psychiatry suggests that the doctors believe there is no pressing organic problem. When people with factitious disorder are confronted with irrefutable evidence of feigning, they usually angrily refute the irrefutable, or cry and flee the scene (Hamilton et al, 2009), then represent at another hospital, or the same one using a different name. The treatment of people with factitious disorder is difficult and there is little evidence (yet) to guide the clinician. Eastwood and Bisson (2008) reviewed all available case studies and series. They found there was no difference in outcome whether or not 1) patients were confronted with true nature of their behavior, 2) psychotherapy was provided, or 3) psychiatric medication was provided. Occasionally, it is possible to encourage these patients into a therapeutic relationship to address the difficulties of their psychological lives. They have usually suffered emotionally deprived early lives, often coming from homes where illness has been a prominent feature. Often, relatives have also presented with factitious disorder.

RESULTS The meta-analyses showed no significant effects on hospital admissions, ED visits or total costs. Meaningful interpretation of total cost data was limited by a small number of comparisons (n = 8) and high variation across trials. Owing to a lack of data, permutation plots were not calculated for total costs. Fourteen comparisons were eligible for inclusion in a permutation plot charting the effects of self-care support on QoL and hospital admissions for mental health (Figure 17); 10 of these comparisons originated from RCTs with adequate allocation concealment. When hospital admissions were plotted against patient outcomes, the majority of comparisons were located in the lower left-hand quadrant, suggesting that self-care support can reduce utilisation for children and young people with mental health conditions without compromising QoL. A minority of studies were located in the lower right-hand quadrant, suggesting reduced hospital admissions but a marginally compromised QoL. As stated previously, data were limited and findings must be treated with caution. Nine comparisons were eligible for inclusion in a permutation plot charting ED visits against patient outcomes (Figure 18); seven were from RCTs with adequate allocation concealment. Limited data mean that these results must be treated with caution. Behavioural difficulties Five studies evaluated self-care support for children and young people with behavioural difficulties. The flow of studies through the review is depicted in Figure 19. Owing to the small number of data available for meta-analysis, meaningful interpretation of the evidence base for non-asthma physical health conditions is limited. Pooled ESs are presented in Table 6 for completeness. Table 7 summarises the results of all meta-analyses, presented according to LTC type.

Studies were categorised according to whether the self-care intervention targeted children (aged 0–12 years), adolescents (aged 13–18 years) or both (Table 8). Across all three age groups, self-care support had statistically significant but minimal effects (ES of < 0. Self-care support was associated with a statistically significant but minimal reduction in ED use for children. Irrespective of the target age group, self-care support had no statistically significant effects on hospital admissions or total costs. Variation in the magnitude of ESs observed across the three subgroups will in part reflect differences in the number of studies available and the precision of the pooled estimates. Analyses of different types of self-care support When different intensities of self-care support were compared, intensive facilitation conferred limited benefit over and above other forms of self-care support (Table 9). Intensively facilitated or case-managed self-care support interventions produced statistically significant but minimal benefits in QoL (ES –0.
