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. The aim of treatment is for the patient to gain insight into their emotional lives and learn more adaptive methods of communicating their emotional needs and dealing with their distress. This calls for a long-term commitment by both the patient and the treating clinicians. Psychotherapy of most forms (in spite of the findings of Eastwood and Bisson (2008)) may have something to offer. The important component is a trusted therapist (family physician, mental health professional) with whom the patient can explore events of their lives as they present. Accordingly, legal authorities must be alerted when a case is suspected/detected (Bass and Glaser, 2014). Debate continues as to whether this condition is adequately diagnosed. An Australian study found Munchausen by proxy is the appropriate diagnosis in 1. The children are generally less than 5 years of age. The time from first presentation to diagnosis in around 22 months – by which time, 6% of the children are dead. Munchhausen by internet is a new phenomenon: the individual fakes a recognized illness, and may attach themselves to online support groups (Pulman and Taylor, 2012). It is possible that on occasions this is with malicious intent, but this method also allow the individual to gain a sense of belonging and support.

Malingering does not appear in the main body of the DSM-5, as it is not considered a legitimate disorder. Up to 30% (Mittenbert et al, 2001) or 40% (Larrabee et al, 2008) of those seeking disability, workers compensation and other form of damages are probably malingering. Mental health professionals with special interest and training are employed, in the private medico-legal rather than the public clinical setting, in the detection of malingering. This is usually in response to claims for compensation following a claimed accident; often the claims involve decreased cognitive ability. A large number of neuropsychological tests have been designed to detect malingering. Many depend on the fact that if patients are guessing, they must get the right answer 50% of the time; malingerers produce statistically significantly more wrong answers than they could by chance (Vitacco et al, 2006). There are also special tests for special circumstances/conditions, such as those designed to distinguish genuine symptoms of PTSD form faked symptoms of PTSD (Gray et al, 2010). The 15 Item memory test (Lezak, 1976) is a simple example of a mechanism which has been used when individuals are claiming memory difficulties. The individual is shown the 15 items (depicted below) for 10 seconds, along with the advice that there are “15 items” and that this is “a very difficult test”. The individual is then asked to write down all figures he/she can remember.

The management of AF and its complications is responsible for almost $16 billion in 14 costs to the U buy 100 mg cafergot with amex. This substantial public health impact of AF in the United States led the Institute of Medicine (IOM) to designate AF as one of the top priority areas for comparative effectiveness research purchase 100 mg cafergot with visa. Specifically buy cheap cafergot 100mg line, the IOM called on researchers to compare the effectiveness of treatment strategies 15 for AF, including surgery, catheter ablation, and pharmacological treatment. Treatment Strategies Management of AF involves three distinct areas: rate control (treatments to slow the heart rate to a normal range), rhythm control (treatments to revert the heart rhythm back to normal), and prevention of thromboembolic events. This Comparative Effectiveness Review (CER) covers the first two areas. A separate CER focusing on stroke prevention in patients with AF, also commissioned through the Evidence-based Practice Center Program of the Agency for Healthcare Research and Quality (AHRQ), is being conducted in parallel with this CER. Rate Control Whether or not a rhythm-control strategy is adopted, current treatment guidelines suggest that adequate rate control should be achieved in all patients with AF to prevent myocardial infarction (if significant coronary artery disease is present), exacerbation of heart failure, and ES-1 tachycardia-induced cardiomyopathy; to alleviate symptoms; and to improve exercise tolerance and quality of life. Thus, the 2006 Guidelines for the Management of Patients with Atrial Fibrillation—prepared jointly by the American College of Cardiology (ACC), the American Heart Association (AHA), and the European Society of Cardiology (ESC)—highlight the need for adequate rate control in patients with AF and designate measurement of the heart rate at rest and control of the rate with pharmacological agents (either a beta blocker or a nonhydropyridine calcium channel blocker in most patients) as a Class I recommendation (evidence and/or general 14 agreement that a given procedure or treatment is useful and effective). However, since the development of the ACC/AHA/ESC Guidelines, many additional studies have been published on the comparative safety and effectiveness of the different available medications used for ventricular rate control in clinical practice. If pharmacological therapy is insufficient for rate control and symptom management or is associated with side effects, the 2006 ACC/AHA/ESC Guidelines recommend ablation of the atrioventricular node (AVN) in conjunction with permanent pacemaker implantation to control 14 heart rate. As the latter involves implantation of an indwelling device that is not reversible, it is considered a treatment of last resort for patients for whom initial pharmacotherapy was ineffective. However, the most recent systematic review on this topic was published more than a decade ago. This review synthesizes the evidence that has been published since then to better define the role of AVN ablation plus pacemaker implantation in contemporary clinical practice and in specific subpopulations where it might be more or less effective and clinically needed. Another clinical dilemma is whether patients with AF do better with strict or lenient rate control. In theory, strict control could reduce symptoms and prevent complications. However, stricter control requires more intensive use of medications, which carry their own side effects. The 2011 Focused Update on the Management of Patients With Atrial Fibrillation by the American College of Cardiology Foundation (ACCF), the AHA, and the Heart Rhythm Society 16 (HRS) addressed the issue of strict versus lenient rate control in patients with AF. Specifically, these guidelines emphasized the following Class III recommendation (evidence and/or general agreement that the procedure/treatment is not useful/effective and in some cases may be harmful): “Treatment to achieve strict rate control of heart rate (<80 bpm at rest or <110 bpm during a 6-minute walk) is not beneficial compared with achieving a resting heart rate <110 bpm in patients with persistent AF who have stable ventricular function (left ventricular ejection 16 fraction >0. Rhythm Control If patients with AF continue to have significant symptoms despite adequate rate control through either pharmacological therapy or AVN ablation, then a rhythm-control strategy (either ES-2 pharmacological or electrical) is currently recommended. For pharmacological cardioversion of AF, the 2006 ACC/AHA/ESC Guidelines recommend flecainide, dofetilide, propafenone, and ibutilide as Class I recommendations, and amiodarone as a Class IIa recommendation (weight of 14 evidence/opinion is in favor of usefulness/efficacy). To enhance direct-current cardioversion, the 2006 ACC/AHA/ESC Guidelines recommend pretreatment with amiodarone, flecainide, ibutilide, propafenone, or sotalol. For maintenance of sinus rhythm after cardioversion, the 2006 ACC/AHA/ESC Guidelines list different antiarrhythmic medications for different clinical settings. The 2011 ACCF/AHA/HRS Focused Update builds on the recommendations in the 2006 ACC/AHA/ESC Guidelines using published data on new antiarrhythmic medications. However, which of these medications is best for which patients is uncertain. Therefore, this report reviews existing evidence and summarizes current evidence gaps on the comparative safety and effectiveness of available antiarrhythmic agents for conversion of AF to sinus rhythm, for facilitating successful electrical cardioversion, and for maintaining sinus rhythm after successful conversion of AF to sinus rhythm. In addition to pharmacological and direct-current cardioversion, a number of surgical interventions are used for rhythm control. Catheter ablation for the treatment of AF, with pulmonary vein isolation (PVI) being the most commonly used ablation, has evolved rapidly from a highly experimental procedure to its current status as a commonly performed procedure that is widely regarded as a clinically useful treatment option for symptomatic patients with AF 14,16,18 in whom medications are not effective or not tolerated. Many studies have provided information on the safety and efficacy of catheter ablation of AF. These studies vary from small and large single-center nonrandomized studies to multicenter prospective randomized controlled trials (RCTs). The relatively small number of patients included in each trial makes definitive conclusions about the safety and efficacy of PVI based on an individual study difficult and does not permit meaningful analyses of key subgroups of patients (e. None of the trials provides data on final outcomes such as mortality and stroke. Although the ongoing Catheter Ablation versus Antiarrhythmic Drug Therapy for AF (CABANA) study will provide important information on the effect of catheter ablation on final 19 outcomes, this trial is not expected to end until several years from now. The present review will increase the power of existing studies by synthesizing the evidence on this procedure by pooling data from existing studies and by exploring whether other types of studies or comparative effectiveness research would be helpful.

SENESCENCE AND DEMENTIA “An old man is twice a child” Shakespeare (Hamlet) SENESCENCE/AGING Senescence (Latin, senex: “old man” or “old age”) is the combination of processes which follow the period of development of an organism. Aging is generally characterized by declining ability to respond to stress and increased risk of disease. Accordingly, death may be seen as the inevitable consequence of aging. A controversial view is that aging is itself a “disease” which may be curable. A related and interesting definition: Aging represents a state of complex multifactorial pathways that involve and ongoing molecular, cellular, and organ damage causing functional loss, disease vulnerability and eventual death (Fontana et al, 2010). Memory loss is a less prominent feature of normal ageing than has sometimes been supposed. Healthy older people do not perform quite as well on objective memory tests as healthy younger people. However, normal aging does not cause functional decline, and ability to perform the normal activities of daily living is maintained. As we get older we slow down both physically and mentally. It takes longer to do normal tasks, including mental tasks like calculations and solving puzzles. It also takes longer to interpret new information, particularly visual-spatial information – which explains why older drivers have more accidents at intersections than on the open road. Executive function and the ability to put together the “big picture” also declines with age. This may explain why some people who have functioned in highly demanding roles are “perfectly happy”, in retirement, to occupy themselves with “odd-jobs about the house”. While these people may have filled their lives with many new activities, slowing down of mental functions and greater focus on details may also partly underpin this happy state of affairs. When people with mild cognitive problems are followed up for 5 years, 80% have developed dementia (Godinho et al, 2011). A recent study of people over 65 years found – cognitive impairment but no dementia, 14. The clustering of white matter lesions (WML) in the temporal region identifies individuals at increased risk of both mild-NCD or dementia (Mortamais et al, 2013). Apathy in mild-NCD and dementia is associated with abnormalities in the frontal regions and anterior cingulate (Stella et al, 2013). Evidence of mild cognitive decline from a previous level of performance in one or more cognitive domains (language, memory, social cognition etc) 1. Deficits to not interfere with capacity for independence (paying bills, medication – but greater effort and strategies may be necessary). Deficits not better explained by another mental disorder DEMENTIA Dementia (Latin, de- “away” + mens “mind”) causes distress to afflicted individuals and family members. It is costly for the community, and relatively unresponsive to current treatment. It is a common disorder and the prevalence is increasing. Dementia affects >1% of people aged 60-64, and the prevalence doubles every 5 years after 60 years of age, reaching 30-50% of people >85 years. The proportion of people surviving into old age is increasing, and it is this group which provides most cases of dementia. Dementia is a set of symptoms, and like cough and fever, this set of symptoms may result from various disorders/diseases. However, to meet diagnostic criteria, there must also be decline in one other area of cognition. The term cognition (Latin, cogito, “to think”) refers to the human processing of information, and includes domains such as language, praxis, gnosis, visuospatial ability and executive function. Particular types of dementia (vascular dementia, for example) have additional diagnostic criteria (focal neurological signs, in the case of vascular dementia). Other diagnostic systems place greater diagnostic importance on the presence of “global deterioration in function” (including self-care and activities of daily living). The “cognitive paradigm” is the view that memory and language disorders are the primary symptoms of dementia.

All-Cause Mortality 218 In one study and within 1 year of followup, 1 out of 53 patients in the all PVI group died compared with 0 out of 52 patients in the selected (arrhythmogenic) PVI group. In another 71 238 study, the 4-year actuarial survival was 98. Quality of Life/Functional Status/Control of AF Symptoms 255 In one study, there was no significant difference in the control of AF symptoms between 271 the single PVI vs. In another study and within 9 months of followup, there was no significant difference in the control of AF symptoms between the PVI group and the PVI + two linear lesions (one between the superior PVs and one from the left inferior PV to the mitral valve annulus) (low strength of evidence). Stroke 238 In one study, the 1- and 3-year actuarial survival free from stroke rates were both 100 percent in the left atrial group, and 98. Other Outcomes None of the studies reported on cardiovascular mortality, CV hospitalizations, heart failure symptoms, mixed embolic events including stroke, bleeding events, or other adverse events. Transcatheter PVI Alone Versus Transcatheter PVI Plus Postablation Antiarrhythmic Drugs Overview 229,234 Two studies compared PVI alone with PVI plus postablation AADs. Results for outcomes of interest are described qualitatively below. Recurrence of AF 234 In one study and during 12 months of followup, AF recurred in 18 out of 53 patients who received no AAD postablation compared with 16 out of 54 patients who received an AAD 229 postablation (p=0. The other study showed that within 6 weeks post-PVI, AF recurred significantly more in the group of patients who received no AAD after ablation than the group of patients who received an AAD after ablation (15/57 vs. Given the inconsistency in findings and varying followup times, we determined the strength of evidence to be insufficient. CV Hospitalizations No study reported generally on CV hospitalizations. One reported specifically on AF 229 hospitalizations. This study showed no significant difference between the AAD arm and no AAD arm (low strength of evidence). Composite Outcomes 229 One study examined a composite outcome of (1) atrial arrhythmias lasting >24 hours; (2) atrial arrhythmias associated with severe symptoms requiring hospital admission, cardioversion, or initiation/modification of AAD therapy; and (3) intolerance to antiarrhythmic agent requiring 72 drug cessation or change. Within 6 weeks, the rate of this outcome was significantly lower in the AAD arm than in the no AAD arm (10/53 vs. Other Outcomes Neither study reported on restoration of SR, all-cause or cardiovascular mortality, heart failure symptoms, control of AF symptoms, quality of life, stroke, mixed embolic events including stroke, or bleeding events,. Adverse Events 234 229 One study did not report any adverse events. In the second study three patients in the AAD group experienced side effects, presumably related to the antiarrhythmic agent, requiring drug cessation. These side effects consisted of a skin rash, severe fatigue, and recurrent severe headaches. Surgical Maze Versus Standard of Care (Mitral Valve Surgery) Overview 214,231,240,242,243,248,254,263 We identified eight RCTs for this comparison, and the available data were deemed appropriate for a meta-analysis for the following outcomes: maintenance of sinus rhythm and all-cause mortality. Results for other outcomes are described qualitatively below. Maintenance of Sinus Rhythm Seven studies evaluated maintenance of sinus rhythm in patients undergoing surgical Maze 214,240,242,243,248,254,263 versus standard of care (specifically mitral valve surgery). A meta-analysis of these 7 studies included 361 patients and estimated an OR of 5. There was significant heterogeneity, which—despite the large estimated benefit—reduced our strength of evidence rating. Although 243,248 the two outlier studies were both fair-quality studies where the randomization and reason for exclusion of specific patients from either randomization or analysis were unclear, the other five studies were also variable in quality (four fair- and one good-quality study) with small samples, and unclear methods.

A meta-analysis of these 6 studies included 387 patients and estimated an OR of 1. Note that the study by Akpinar and colleagues was performed in Turkey and involved a small number of deaths, several of which were, according to the study authors, unrelated to the procedure or cardiovascular in nature (e. Reviewing the timing of mortality within the Maze groups for the included studies, the 240 mortality in one study occurred from septic shock after pneumonia 17 days postprocedure; 242 none of the deaths in another study were considered related to the procedure; in a third 243 study, 1 death in the Maze group was immediate and caused by tamponade/reoperation, and 2 additional deaths occurred 57 days and 20 months postprocedure and were caused by acute renal failure/septic shock and coronary artery dissection during catheterization, respectively. In 248 th another study, there was 1 hospital death on the 57 postoperative day, caused by sepsis, in a 214 patient who underwent the Maze procedure. In another study, 1 patient within the Maze group died after 40 days due to renal bleeding under standard anticoagulation as performed after prosthetic mitral valve implantation (INR 2·5 to 3·5). One patient died after 45 days from mediastinitis; 1 sudden cardiac death occurred after 4 months; and 1 death due to respiratory insufficiency followed severe lung fibrosis after 7 months. As detailed, many of these deaths in the Maze arm were most likely not related to the procedure itself.
