Frequency of ICD-10 Factitious Disorder: Survey of Senior Hospital Consultants and Physicians in Private Practice

[Factitious disorder imposed on self and Munchausen syndrome: An update]

Factitious disorder imposed on self (FDIS) is a mental disorder characterized by conscious manipulative behavior from patients with no clearly identifiable external objective. It affects subjects with a wide range of characteristics, only some of whom fit the stereotypical profile of the young female working in the health sector. It can take the form of a variety of symptoms or clinical signs, and is likely to involve all specialties. Munchausen syndrome is a particular form of FDIS, more prevalent in men and marked by its severity. Psychiatric comorbidities are common in patients with FDIS. Death is rare but possible, either as a result of the disease itself, complications of examinations or treatments, or suicide. The diagnostic approach must seek to identify positive arguments in favor of the disorder. Diagnosis by elimination remains possible when no other hypothesis can explain a clinical picture suggestive of FDIS. The prognosis is often poor, at least in the short and medium term. Avoiding unnecessary prescriptions is essential to prevent iatrogenesis. The management of FDIS is poorly codified. In all cases, the practitioner must adopt a non-aggressive, empathetic attitude.

Factitious disorder imposed on self: A retrospective study of 2232 cases from health insurance databases

OBJECTIVE

Patients with factitious disorder imposed on self (FDIS) seek medical care for deliberately falsified problems. Although a large amount of work has been published, the scientific literature lacks robust data on FDIS. The present study aimed to estimate the annual mean of in-hospital FDIS codings in France, describe the sociodemographic characteristics of subjects with FDIS, assess healthcare utilisation and medical nomadism, and describe the pathologies most frequently associated with FDIS.

METHOD

Subjects with at least one coding of FDIS in French health insurance databases between January 1, 2009, and December 31, 2017 were included. Subjects younger than 18 years of age at the time of first coding were excluded from the study. Sociodemographic data of subjects and diagnoses associated with the first coding of FDIS were collected. Healthcare utilisation and medical nomadism were analysed descriptively from one year before to one year after the first FDIS coding.

RESULTS

2232 subjects were included, representing an average of 248 new in-hospital FDIS codings per year. The subjects included were 58.2% female. The mean age at diagnosis was 48.5 years. In the year following the first coding of FDIS, 1268 subjects (56.8%) were re-hospitalised at least once, including 159 (7.1%) with at least one new coding for FDIS. From one year before to one year after the first coding of FDIS, 66% of the subjects included had received at least one prescription for benzodiazepines, 58.3% for antidepressants, and 42.6% for antipsychotics.

CONCLUSIONS

Our findings bring new data working towards a better understanding of FDIS. The consumption of psychotropic drugs is particularly frequent in patients with FDIS.

Clinical impact and misdiagnosis of functional ophthalmological symptoms: a case report

BACKGROUND

There is a high prevalence of somatoform disorders and medically unexplained symptoms. When it comes to deciding whether a patient is able to work, it is essential to differentiate a somatoform disorder from a factitious disorder. The case presented demonstrates the impact on disability benefits and the subsequent psychosocial repercussions of misdiagnosing between a factitious disorder and a somatoform disorder.

CASE PRESENTATION

A 42-year-old Caucasian woman worked as a 100% fiduciary accountant until the age of 32 when she was placed on medical leave due to persistent trigeminal neuralgia. Afterward, she developed total blindness, not explained by a physiological process, accompanied by distress in a crucial emotional context. We evaluated the patient for a revision of a disability income after a diagnosis of factitious disorder with severe consequences such as disability income suspension and family conflict. Our psychiatric examination concluded the diagnoses of pain disorders related to psychological factors and a dissociative neurological symptom disorder with visual disturbance.

CONCLUSIONS

Blindness not explained by a physiological process may accompany trauma and psychological distress. Differentiating this pathology from factitious disorder or simulation is essential from an insurance medicine point of view, but also for its treatment.

Clinical characteristics and comorbidities of the most common atypical wounds in Northern Finland in 1996-2019: A retrospective registry study

Background and Aims

Atypical wounds comprise about 20% of all chronic wounds. Their diagnosis and treatment are challenging and require multidisciplinary cooperation. More knowledge is needed about the clinical characteristics and comorbidities of atypical wounds to enhance the treatment of these wounds.

Methods

We studied clinical characteristics and comorbidities of the atypical wounds by using the patient data retrieved from the Oulu University Hospital patient database from the year 1996 to the end of 2019 with the following International Classification of Diseases codes: L88, L95.0, L95.8, L95.9, and L98.1.

Results

In our data, there were 135 patients with atypical wound, more commonly seen in females (N = 84, 62.2%) than in males (N = 51, 37.8%) (p < 0.05). The mean age of patients at the time of diagnosis was 57.3 years; those with pyoderma gangrenosum (PG) and factitious wounds were the youngest (53.1 and 53.0 years, respectively). The majority of subjects (N = 126, 93.3%) were diagnosed with comorbidity at the time of the diagnosis. The most common type of wound was PG (N = 49/135, 36.3%), followed by vasculitis and factitious wounds. The prevalence of inflammatory bowel diseases and rheumatoid arthritis in PG patients was high (18.4% for both). All patients with Martorell hypertensive ischemic leg ulceration/calciphylaxis had a diagnosis of hypertension and diabetes mellitus. Psychiatric diseases were more common in patients with factitious wounds than in other types of wounds, whereas patients with vasculitis wounds had more commonly hypertension, obesity, and diabetes mellitus; however, these did not reach statistical significance.

Conclusion

Specific comorbidities associated with atypical wounds, such as high psychiatric comorbidity in factitious wounds. There is a female predominance in atypical wounds and patients are typically younger than patients with other types of wounds. Recognition of the typical clinical picture and comorbidities of atypical wounds may help in identifying these patients and thus also improving their treatment.

[Suspected factitious disorder: identifying self-inflicted wounds in plastic surgery]

BACKGROUND

Patients with factitious disorders artificially generate, aggravate or feign injuries or illnesses, which can result in severe physical impairment and misuse of the healthcare system. The symptomatology is characterized by a protracted course of disease with frequent changes of practitioners and multiple invasive procedures due to anomalous, mostly chronic findings. Elaborate clinical presentations, lack of knowledge of disease characteristics and the fast-paced everyday clinical practice can lead to maintaining the disease through non-recognition or mistreatment.

METHODS

Based on selective literature research and clinical case reports from a university clinic for plastic surgery, this article provides a review about common features of factitious disorders as well as treatment strategies.

RESULTS

If a factitious disorder is suspected, invasive treatments should be restricted and psychosomatic or psychiatric expertise obtained. Within an empathic physician-patient relation and with psychotherapeutic support, patients can be gradually introduced to the diagnosis and therapy options and treatment terminations could be avoided.

CONCLUSION

Knowledge of indicators for factitious disorders, which may become evident in medical history, findings and illness-affirming behaviour, is key to identify affected patients and initiate appropriate treatment. For this purpose, factitious disorders should be included in differential diagnostic considerations even in primarily somatic medical specialties. Since the diagnosis is often based on evidence and complicated by withheld information or medical confidentiality, the establishment of a central reporting register could facilitate the diagnostic process and improve therapy in the future.

Factitious Disorder in Seven Patients: A Saudi Experience

Background

Factitious disorder (FD) is a psychiatric disease where signs and symptoms are produced, falsified, or exaggerated consciously in the absence of clear external motivations. Through needless medical visits, costly investigatory testing, and potentially long hospital stays, patients with FD waste valuable time and resources, which affects both the patient and the healthcare system. It can be very challenging for physicians who have never encountered patients with FD to recognize them promptly as symptoms of FD vary greatly.

Methodology

This was a retrospective study of patients diagnosed with FD attending King Abdulaziz Medical City in Riyadh, Saudi Arabia, a tertiary care military hospital and one of the most prominent academic and referral medical institutions in the country. Using the BESTCare health information system, we reviewed patients’ electronic health records from January 2015 to December 2020. The diagnosis of FD was based on the International Classification of Diseases and Related Health Problems 10th edition.

Results

A total of seven patients were included in the study, of whom five (71%) were males and two (29%) were females. Of the total seven patients, three were 21 years old and younger, one was 38 years old, and three were 56 years old and older. Three (43%) patients were married and four (57%) were single. In terms of occupation, three (43%) patients were retired, one (14%) worked in a private company, one (14%) was unemployed, and two (29%) were students. A total of four (57%) patients initially presented to the Emergency Department (ED), and only three (43%) presented to the outpatient clinics. Induced disease or injury was found in five (71%) patients. Induced skin injury was found in four (57%) patients. Counseling and psychotherapy were only offered to one (14%) patient.

Conclusions

FD remains a rare psychiatric condition that is difficult to recognize. Despite a small sample size, FD in the present study showed a male predominance, affecting patients of all age groups. About half of the patients presented initially to the ED. Induced disease or injury was the most commonly reported pattern of clinical presentation. Induced skin injury was the most common clinical presentation found in around half of the patients. We believe that the number of FD patients in the present study is likely underreported and is expected to be higher. This highlights the need for better awareness of FD among physicians in different medical fields. We emphasize that there is a need for better professional training in the identification of FD.

Psychogenic Seizure Imitating Narcolepsy

Psychogenic or functional neurological disorders (FND) often occur in the practice of a neurologist. Diagnosis of FND usually causes significant difficulties. Among FND, psychogenic non-epileptic seizures (PNES) comprise around 40% cases. Sometimes it is necessary to differentiate PNES from narcolepsy. We describe a 55-year-old man with frequent brief and sudden sleep-like attacks in combination with nocturnal sleep disturbance. During attacks he was unresponsive, snoring but maintained posture. He resisted passive eye opening but with rolling eyes. The patient was confused on waking. In the interictal period, there were FND signs including give-way weakness of the left hand, typical functional “leg-dragging” gait, mistake in the finger-to-nose test. Video-electroencephalogram monitoring did not detect specific epileptic activity or sleep pattern during the attacks. Polysomnography showed multiple waking episodes during the night, but no typical pattern of narcolepsy was found in the multiple sleep latency test. The patient had frequent urgent hospitalizations due to different diseases and numerous invasive procedures. Six month later, the patient obtained state related disability financial benefit, after which hospitalizations in various hospitals continued, and PNES became shorter and less pronounced.

Factitious Disorders in Everyday Clinical Practice

BACKGROUND

The pathological feigning of disease can be seen in all medical disciplines. It is associated with variegated symptom presentations, self-inflicted injuries, forced but unnecessary interventions, unusual and protracted recoveries, and frequent changes of treating physician. Factitious illness is often difficult to distinguish from functional or dissociative disorders on the one hand, and from malingering on the other. Many cases, even fatal ones, probably go unrecognized. The suspicion that a patient's problem may be, at least in part, factitious is subject to a strong taboo and generally rests on supportive rather than conclusive evidence. The danger of misdiagnosis and inappropriate treatment is high.

METHODS

On the basis of a selective review of current literature, we summarize the phenomenology of factitious disorders and present concrete strategies for dealing with suspected factitious disorders.

RESULTS

Through the early recognition and assessment of clues and warning signs, the clinician will be able to judge whether a factitious disorder should be considered as a differential diagnosis, as a comorbid disturbance, or as the suspected main diagnosis. A stepwise, supportive confrontation of the patient with the facts, in which continued therapeutic contact is offered and no proofs or confessions are demanded, can help the patient set aside the sick role in favor of more functional objectives, while still saving face. In contrast, a tough confrontation without empathy may provoke even more elaborate manipulations or precipitate the abrupt discontinuation of care-seeking.

CONCLUSION

Even in the absence of systematic studies, which will probably remain difficult to carry out, it is clearly the case that feigned, falsified, and induced disorders are underappreciated and potentially dangerous differential diagnoses. If the entire treating team successfully maintains an alert, transparent, empathic, and coping-oriented therapeutic approach, the patient will, in the best case, be able to shed the pretense of disease. Above all, the timely recognition of the nature of the problem by the treating team can prevent further iatrogenic harm.

Munchausen Syndrome by Tissue Plasminogen Activator: Patients Seeking Thrombolytic Administration

Purpose of Review

Munchausen syndrome by tissue plasminogen activator (tPA) is a phenomenon we describe as patients exhibiting factitious symptoms to assume the role of the sick patient, desiring and received tPA, with no alternative diagnosis or secondary gain to better account for their presentation. To illustrate this phenomenon and its magnitude, we present a series of cases of Munchausen syndrome by tPA, prevalence in our stroke center, and highlight one illustrative case.

Recent Findings

Of 335 cases with tPA administration over 29 months, 10 were confirmed as Munchausen syndrome by tPA, reflecting a 3.0% prevalence in our stroke center.

Summary

Munchausen syndrome by tPA is an underappreciated phenomenon encountered in evaluating patients with acute stroke symptoms. Administering tPA in Munchausen syndrome poses an ethical dilemma because standard of care favors rapid tPA administration, but administration can cause harm, burdens the healthcare system, and does not treat the patient's Munchausen syndrome.

Clinical, demographic, psychological, and behavioral features of factitious disorder: A retrospective analysis

BACKGROUND

Consultation psychiatrists are often asked to assess factitious disorder (FD), yet this is challenging as confirmation depends on rarely achieved direct evidence of illness-inducing behaviors. Diagnosis is thus based on other variables, such as atypical features of the medical presentation and certain patient behaviors. This study sought to assess a cohort of patients with FD for demographic and clinical variables, but also psychological and behavioral ones unexamined in previous studies.

METHODS

49 previously-identified FD patients at a single site were reviewed retrospectively and variables collected included demographic, medical, psychiatric, social, behavioral, and treatment-related. Descriptive statistical analysis was used.

RESULTS

Patients were mostly: 1) under age 40 (82%), 2) female (90%), 3) with past psychiatric (92%), family psychiatric (78%), and traumatic (69%) histories; 4) direct intravenous access (67%); and 7) some exposure to healthcare training (67%). All (100%) subjects had an identifiable family dynamic issue, including household abuse, parental divorce, parental influence/enmeshment, grief, and/or significant other conflict. Financial, emotional, or social incentives were common, and most patients (88%) exhibited at least 4 FD-related behaviors.

CONCLUSION

FD represents a complex disorder of abnormal illness behaviors with predisposing developmental and perpetuating sociobehavioral variables previously unexplored. Future investigational, educational, and quality improvement directions are considered.

Triparesis: an unusual presentation of factitious disorder

Factitious disorder (FD) has diverse presentations but neurological presentation is unusual. In this report, we discuss a case of FD who presented with triparesis, that is, weakness of both lower limbs and right upper limb. Diagnosis of FD was made after detailed clinical evaluation, review of past medical records that revealed extensive evaluation to rule out physical illness, and inability to find any associated stressful event or material gain associated with illness. Management was largely supportive and was based on psychotherapy. Identification of FD depends on a high index of suspicion by the physician and the presence of atypical and medically unexplainable signs/symptoms.

An Overview of Munchausen Syndrome and Munchausen Syndrome by Proxy

Munchausen syndrome and Munchausen syndrome by proxy are complex diseases that are difficult to diagnose and treat. To assist in this process, an overview of diagnostic criteria with common characteristics and red flags are discussed, with case studies illustrating identification and diagnosis of these disorders. Treatment options are addressed within the context of each of these complex syndromes. The provider's knowledge of diagnostic criteria and treatment options for Munchausen syndrome and Munchausen syndrome by proxy promotes better outcomes for patients. Without an early diagnosis and intervention, the patient is at high risk for severe complications, including organ failure and mortality.

Differentiating factitious psychological presentations from malingering: Implications for forensic practice

Practitioners and researchers have long been challenged with identifying deceptive response styles in forensic contexts, particularly when differentiating malingering from factitious presentations. The origins and the development of factitious disorders as a diagnostic classification are discussed, as well as the many challenges and limitations present with the current diagnostic conceptualization. As an alternative to a formal diagnosis, forensic practitioners may choose to consider most factitious psychological presentations (FPPs) as a dimensional construct that are classified like malingering as a V code. Building on Rogers' central motivations for malingering, the current article provides four explanatory models for FPPs; three of these parallel malingering (pathogenic, criminological, and adaptational) but differ in their central features. In addition, the nurturance model stresses how patients with FPPs attempt to use their relationship with treating professionals to fulfill their unmet psychological needs. Relying on these models, practical guidelines are recommended for evaluating FPPs in a forensic context.

Fabricated facial rash - an unusual presentation of factitious disorder

Patients with factitious disorder typically present with signs or symptoms suggesting a medical problem, but which transpire to be self-induced or fabricated. Repeated investigations and treatments are often carried out to no avail before this possibility is considered. In this case, a 51-year-old female presented to the oral and maxillofacial surgery unit with toothache and a facial rash. Following admission to hospital a range of investigations were performed, and a tooth was extracted. Judicious attention by nursing staff led to the discovery that the patient had been applying make-up to mimic a skin rash. This concern was raised with the patient and she admitted falsifying the rash. Although this patient may have been experiencing pain, by applying make-up in this manner she sought to exaggerate the severity of her condition and as a result underwent potentially unnecessary procedures. This case provides a reminder that the possibility of factitious disorder should be considered in cases where patients present with symptoms or signs which appear fabricated or self-inflicted, defy anatomical or physiological principles, or do not correlate with the history. Thorough history taking is essential, and access to electronic care records may be informative. Psychiatric follow-up is recommended, but not all patients are willing to engage with this process.

Hypoglycemia secondary to factitious hyperinsulinism in a foster care adolescent - a case report of munchausen syndrome in a community hospital emergency department setting

Background

Factitious disorder causing hypoglycemia is a psychiatric condition in which patients deliberately use blood sugar lowering medications to cause severe symptoms for the purposes of hospitalization or other primary gains.

Case presentation

We report a case of factitious hypoglycemia in a 19-year-old foster care adolescent female who presented to the Emergency Department with recurrent hypoglycemic episodes, to the degree that the patient required large amounts of dextrose and further management by intensive care unit hospitalization. Further inquiry revealed that the patient intentionally injected herself with large doses of insulin for the purposes of seeking hospital admission.

Conclusion

Factitious disorder in the setting of recurrent hypoglycemia episodes may warrant a psychiatric referral and appropriate discharge follow-up to avoid multiple hospitalizations. Presentation in a non-diabetic patient from insulin use is a type of illness that is a challenge for emergency department physicians to appropriately diagnose and treat. Classic findings include a low blood sugar level, suppressed C-peptide level, and an inappropriately elevated insulin level. Recognizing these psychiatric presentations is crucial in order to stabilize patients and prevent unnecessary testing.

Factitious hypoglycemia in children and adolescents with diabetes

BACKGROUND

Factitious hypoglycemia is a condition of self-induced hypoglycemia due to surreptitious administration of insulin or oral hypoglycemic agents. In adults, it is an uncommon, but well known clinical entity observed in individuals with and without diabetes.

OBJECTIVES

To report a case of factitious hypoglycemia highlighting diagnostic pitfalls, to identify common characteristics of children and adolescents with factitious hypoglycemia, and to examine whether the information on long-term outcome exists.

METHODS

We present a case of an adolescent with type 1 diabetes who had self-induced hypoglycemia of several years' duration; and we conducted a systematic literature review on factitious hypoglycemia in pediatric patients with diabetes.

RESULTS

We identified a total of 83 articles of which 14 met the inclusion criteria (describing 39 cases). All but 1 individual had type 1 diabetes and the majority was female (63%). Average age was 13.5 ± 2.0 years with the youngest patient presenting at the age 9.5 years. Blood glucose control was poor (hemoglobin A1c: 12.1 ± 4.0%). In 35%, psychiatric disorders were mentioned as contributing factors. Only 3 reports provided follow-up beyond 6 months.

CONCLUSIONS

Factitious hypoglycemia typically occurs in adolescents with type 1 diabetes who use insulin to induce hypoglycemia. Awareness of this differential diagnosis and knowledge of potentially misleading laboratory results may facilitate earlier recognition and intervention. Little information exists on effective treatments and long-term outcome.

A Case of Munchausen Syndrome Presenting with Hematemesis: A Case Report

Munchausen syndrome (MS) was first reported in 1951 by Richard Alan John Asher as a factitious disorder. It is a condition in which the patient intentionally produces symptoms to assume a sick role and gain medical attention. Underdiagnosis of this disorder results in the unnecessary use of medical resources, i.e. unnecessary medical tests and evaluations. This makes it one of the most challenging diagnosis in any medical set up. We present this rare case of a patient with chronic factitious disorder who presented to the emergency with hematemesis. The patient was successfully treated with psychotherapy with no recurrence. It is the need of the hour to create awareness amongst the medical and nonmedical population about factitious disorders so that they can easily be diagnosed and treated with efficiency. Further research is needed to find the risks leading to this syndrome and discover the cultural and social aspects of this disease, which may help us explore treatment strategies and avoid unnecessary tests and treatment.​

[Factitious disorders]

Patients with factitious disorders intentionally fabricate, exaggerate or feign physical and/or psychiatric symptoms for various open and covert psychological reasons. There are many issues regarding the diagnostic state and classification of factitious disorders. Both the categorical differentiation of and clinical continuum ranging from somatoform/dissociative disorders to malingering are being controversially debated. Epidemiological studies on the frequency of factitious disorder meet basic methodological difficulties. Reported rates of prevalence and incidence in the professional literature most probably have to be considered underestimations. Illness deception and self-harm as core features of the abnormal illness behaviour in factitious disorder may refer to various highly adverse and traumatic experiences during early development in a subgroup of patients. Chronic courses of illness prevail; however, there are also episodic variants.

Factitious Disorder in a Patient Claiming to be a Sexually Sadistic Serial Killer

Factitious disorder involves the conscious simulation of psychological or physiological symptoms of illness, for the purpose of fulfilling the unconscious desire to be taken care of or to assume the "sick role." Typically patients with factitious disorder simulate conditions that are designed to arouse feelings of empathy in care providers with the intention to engage them in caretaking. However, patients might also simulate conditions that arouse revulsion or rejection and still meet full diagnostic criteria for factitious disorder. In this case report, we present a patient who fabricated an elaborate history of being a sexually sadistic serial killer with homicidal ideation with the intention of obtaining personal attention, nurturance, and empathy from his psychotherapist. However, given the nature of his feigned condition, the patient frightened the very person whom he sought to engage in caretaking.

Factitious disorder: a systematic review of 455 cases in the professional literature

OBJECTIVE

Patients with factitious disorder (FD) fabricate illness, injury or impairment for psychological reasons and, as a result, misapply medical resources. The demographic and clinical profile of these patients has yet to be described in a sufficiently large sample, which has prevented clinicians from adopting an evidence-based approach to FD. The present study aimed to address this issue through a systematic review of cases reported in the professional literature.

METHOD

A systematic search for case studies in the MEDLINE, Web of Science and EMBASE databases was conducted. A total of 4092 records were screened and 684 remaining papers were reviewed. A supplementary search was conducted via GoogleScholar, reference lists of eligible articles and key review papers. In total, 372 eligible studies yielded a sample of 455 cases. Information extracted included age, gender, reported occupation, comorbid psychopathology, presenting signs and symptoms, severity and factors leading to the diagnosis of FD.

RESULTS

A total of 66.2% of patients in our sample were female. Mean age at presentation was 34.2 years. A healthcare or laboratory profession was reported most frequently (N=122). A current or past diagnosis of depression was described more frequently than personality disorder in cases reporting psychiatric comorbidity (41.8% versus 16.5%) and more patients elected to self-induce illness or injury (58.7%) than simulate or falsely report it. Patients were most likely to present with endocrinological, cardiological and dermatological problems. Differences among specialties were observed on demographic factors, severity and factors leading to diagnosis of FD.

CONCLUSIONS

Based on the largest sample of patients with FD analyzed to date, our findings offer an important first step toward an evidence-based approach to the disorder. Future guidelines must be sensitive to differing methods used by specialists when diagnosing FD.

Underlying Mechanisms in Episodic Laryngeal Breathing Disorders

The study and management of episodic laryngeal breathing disorders (ELBD)—characterized by paradoxical laryngeal movement patterns and dyspnea—has traditionally focused on clinical presentation of these conditions. However, the underlying mechanisms driving these entities are largely unknown. This article provides a review of potential underlying mechanisms driving clinical expression in ELBD and suggests approaches to the future study of ELBD etiology.

Factitious disorders and malingering in relation to functional neurologic disorders

Interest in malingering has grown in recent years, and is reflected in the exponential increase in academic publications since 1990. Although malingering is more commonly detected in medicolegal practice, it is not an all-or-nothing presentation and moreover can vary in the extent of presentation. As a nonmedical disorder, the challenge for clinical practice remains that malingering by definition is intentional and deliberate. As such, clinical skills alone are often insufficient to detect it and we describe psychometric tests such as symptom validity tests and relevant nonmedical investigations. Finally, we describe those areas of neurologic practice where symptom exaggeration and deception are more likely to occur, e.g., postconcussional syndrome, psychogenic nonepileptic seizures, motor weakness and movement disorders, and chronic pain. Factitious disorders are rare in clinical practice and their detection depends largely on the level of clinical suspicion supported by the systematic collection of relevant information from a variety of sources. In this chapter we challenge the accepted DSM-5 definition of factitious disorder and suggest that the traditional glossaries have neglected the extent to which a person's reported symptoms can be considered a product of intentional choice or selective psychopathology largely beyond the subject's voluntary control, or more likely, both. We present evidence to suggest that neurologists preferentially diagnose factitious presentations in healthcare workers as "hysterical," possibly to avoid the stigma of simulated illness.

Factitious disorder (Munchausen's syndrome) in oncology: case report and literature review

BACKGROUND

Factitious disorder is where patients repeatedly seek medical care for feigned illnesses in the absence of obvious external rewards; 'Munchausen's syndrome' is the historical name for this disorder.

METHOD

We report on a case that was presented to a tertiary oncology center as a suspected rare bone cancer.

RESULTS AND CONCLUSIONS

Psychosocial clinicians working in oncology settings should be aware of the complexities of diagnosing factitious disorder in cancer settings where empathy is prominent and suspicion unusual. Moreover, comorbidity can cloud the diagnosis (in this case substance abuse), and, even when accurately diagnosed, there are no evidence-based management approaches to offer to the patient. What seems to linger most after the patient is discharged, usually in a huff, are strong counter-transference feelings and substantial medical bills. Copyright © 2015 John Wiley & Sons, Ltd.

[The phenomenon of covert self-mutilation in the surgical routine]

Factitious disorders are conditions which are unknown to many physicians but have a prevalence of 1-5 % in outpatient departments and hospitals. In order to avoid prolonged and complicated (false) treatment in surgery this article gives a review of the definition, epidemiology and pathogenesis of factitious disorders as well as clinical symptoms and therapy options. A focus is placed on the identification of patients, treatment strategies and the prevention of malpractice. Additionally, clinical features of the disorder are illustrated with the description of some characteristic cases.

Factitious Disorder in Crohn's Disease: Recurrent Pancytopenia Caused by Surreptitious Ingestion of 6-Mercaptopurine

Factitious disorder is a rare psychiatric illness characterized by the willful and deceptive induction of illness for the purpose of assuming the sick role. It presents a substantial diagnostic challenge, as patients often go to great lengths to conceal their deception. Accordingly, its presence in the full spectrum of gastrointestinal diseases is likely underappreciated. While factitious gastrointestinal bleeding, abdominal pain and diarrhea are relatively common, factitious non-gastrointestinal symptoms in the setting of gastrointestinal illness have been infrequently reported. We present the case of a patient with Crohn's disease with recurrent pancytopenia attributed to the surreptitious ingestion of 6-mercaptopurine. In patients with possible access to immunomodulatory drugs, a high suspicion for and early identification of factitious disorder may improve patient outcomes and avoid invasive and costly diagnostic evaluations.

Factitious disorders and malingering: challenges for clinical assessment and management

Compared with other psychiatric disorders, diagnosis of factitious disorders is rare, with identification largely dependent on the systematic collection of relevant information, including a detailed chronology and scrutiny of the patient's medical record. Management of such disorders ideally requires a team-based approach and close involvement of the primary care doctor. As deception is a key defining component of factitious disorders, diagnosis has important implications for young children, particularly when identified in women and health-care workers. Malingering is considered to be rare in clinical practice, whereas simulation of symptoms, motivated by financial rewards, is regarded as more common in medicolegal settings. Although psychometric investigations (eg, symptom validity testing) can inform the detection of illness deception, such tests need support from converging evidence sources, including detailed interview assessments, medical notes, and relevant non-medical investigations. A key challenge in any discussion of abnormal health-care-seeking behaviour is the extent to which a person's reported symptoms are considered to be a product of choice, or psychopathology beyond volitional control, or perhaps both. Clinical skills alone are not typically sufficient for diagnosis or to detect malingering. Medical education needs to provide doctors with the conceptual, developmental, and management frameworks to understand and deal with patients whose symptoms appear to be simulated. Central to the understanding of factitious disorders and malingering are the explanatory models and beliefs used to provide meaning for both patients and doctors. Future progress in management will benefit from an increased appreciation of the contribution of non-medical factors and a greater awareness of the conceptual and clinical findings from social neuroscience, occupational health, and clinical psychology.

Munchausen syndrome and factitious disorder: the role of the laboratory in its detection and diagnosis

The term Munchausen syndrome is used to describe the patient who chronically fabricates or induces illness with the sole intention of assuming the patient role. Such persons often have a close association with the medical profession and thus use their knowledge to falsify symptoms and laboratory specimens to mimic disease. Cases of factitious disease have appeared in the literature originating from all medical specialties, and include such rare disorders as phaeochromocytoma and Bartter's syndrome. The laboratory can play a key role in the detection and diagnosis of factitious disorders. Indeed discrepant biochemistry results may provide the first clue to the diagnosis. Laboratory staff should be particularly aware of highly variable test results and extreme abnormalities that are not consistent with the wider biochemical profile, suggesting sample tampering. Factitious disorder should also be included in the clinician's differential diagnosis when disease presentation is unusual or an underlying cause cannot be found. Investigation to exclude or confirm factitious disorder at an early stage can prevent unnecessary testing in the search for increasingly rare diseases. Appropriate analyses may include screening tests for the detection of surreptitious drug administration or replication of a fabricated sample to confirm the method used. In all cases close communication between the clinician and laboratory is essential. This will ensure that appropriate tests are conducted particularly with regard to time critical and repeat tests.

Diagnosis and treatment of somatoform disorders

Many patients with somatoform disorders present to the neurology clinic, often after extensive evaluation that has left the patient and multiple other physicians frustrated. Knowledge of the typical characteristics of particular disorders enables the clinician to arrive at a positive diagnosis and facilitate referral to appropriate services. Using a series of representative cases, we review the DSM-IV-TR somatoform disorders most likely to present to the practicing neurologist, highlighting the epidemiologic features, typical presentations, and possible therapeutic approaches to each condition.

Munchausen syndrome mimicking psychiatric disease with concomitant genuine physical illness

Munchausen syndrome is a disorder in which patients intentionally produce symptoms mimicking physical or psychiatric illnesses with the aim to assume the sick role and to gain medical attention. Once a patient receives a Munchausen syndrome diagnosis every complaint made thence tends to be regarded with scepticism by clinical staff. However, it is possible that a bona fide illness, which might be disregarded, may coexist in these patients. We report a case of MS mimicking psychiatric disease with concomitant genuine acute physical illness. Despite the initial doubts about the veracity of the latter, due to its prompt recognition, treatment was successful.

Axis I comorbidity and psychopathologic correlates of autodestructive syndromes

OBJECTIVE

Nonsuicidal deliberate self-harm and factitious disorders have been proposed as subtypes within the autodestructive behavior spectrum, basically differing in the issue of concealment. Aims are to determine Axis I diagnoses and psychopathologic correlates of open self-harmers and patients diagnosed with factitious disorders.

METHODS

One hundred ninety-four psychosomatic medicine inpatients participated. Assessment included the structured World Health Organization Composite International Diagnostic Interview (computerized version) and self-report questionnaires for anxiety, depression, perceived stress, and personal coping resources.

RESULTS

Thirty-seven patients identified with self-destructive behavior were matched with 37 patients without such behavior. Overt self-harmers (n = 18) were more frequently diagnosed with anxiety, depressive, substance abuse/dependence, or eating disorders and reported more stress than factitious disorder patients (n = 19) or those without self-destructive behavior. Patients with factitious disorder exhibited lower Axis I comorbidity and less psychopathology than patients without self-harm behavior.

CONCLUSIONS

Regarding psychopathologic assessment, contrary to open self-harmers, factitious disorder patients appear strikingly inconspicuous.

Challenges in the treatment of factitious disorder: a case study

Factitious disorder is difficult to diagnose and effectively treat. It is often met with intense emotion by both the care provider(s) and the client when suspected. However, if missed or untreated, it can become a chronic syndrome that is expensive and potentially dangerous. This article examines barriers to successful treatment of factitious disorder as manifested by a woman who received services from an urban community mental health center over a 7-year period for the management of multiple mental health issues. The unique role of the advanced practice psychiatric nurse is discussed through application of the nursing theory modeling and role modeling.

Factitious disorders: potential litigation risks for plastic surgeons

Patients with factitious physical disorders can present with a myriad of signs and symptoms. Common presentations include persistent wounds and abscesses that are often treated by plastic surgeons. Because these individuals are surreptitiously trying to maintain their illness, rather than recover, adverse outcomes are common, particularly when the plastic surgeon has not detected the factitious etiology. Well-meaning plastic surgeons trying to help difficult-to-treat patients may be at high risk for poor outcomes with factitious disorder patients. When these outcomes occur, these patients may focus their underlying anger or other feelings on their plastic surgeons and may initiate litigation. This article discusses 2 cases in which plastic surgeons were sued for malpractice by factitious disorder patients. We outline clues to the recognition of factitious disorders and steps the plastic surgeon can take to initiate appropriate treatment, which may reduce the risk of litigation.

[The consequences of subcutaneous India ink injection to produce factitial disease. Bilateral mastectomy, lymph node dissection, irradiation, and continued suspicion of neoplasia]

A 68-year-old woman with insulin-dependent diabetes mellitus presented with blue nodules on the ventral aspect of the thorax. According to the past history, these lesions had developed repeatedly. She had already had bilateral mastectomies and lymph node dissection. The histologic diagnosis was always mastitis with plasma cells and no neoplasia. Yet another biopsy was taken; the subcutis was stained blue-black. Histology revealed exogenous black pigment and mastitis. With Raman spectroscopy the pigment was identified as carbon black, which is a component of India ink. These findings together with the unusual course of the disease suggested the diagnosis of an artificial disorder. The likely conclusion is that our patient, over years, used her own (insulin) syringe to inject India ink into her skin and subcutaneous tissue; the damaging effect and tissue reaction was probably caused by preservatives such as phenol.

["I'd like to have a high-dose chemotherapy with stem cell transplantation!"]

Patients with factitious disorders can imitate complex diseases and cause multiple investigations and therapies. The presented patient showed the typical signs and behaviour of this psychiatric disorder. Confrontation may not be helpful in severe cases, whereas a supportive approach might help to avoid further useless and dangerous procedures.
