BACKGROUND: Medical Child Abuse (MCA) is a severe form of child abuse. In MCA, the caregiver abuses the child by exaggerating, fabricating, simulating, or inducing symptoms, and unnecessary, potentially harmful medical care harms the child. Bleeding is one of the most common manifestations of MCA. Diagnosis of MCA is challenging, and late diagnosis may increase the severity and complications. Once suspected, it is essential to apply all relevant methods of investigation to support and confirm the diagnosis, as soon as possible, as late diagnosis increases the risks.
METHODS: An 18-month-old boy was referred to the Pediatric Hematology by the Department of the Emergency with multiple admissions in a 2-week period for recurrent said-to-be bleeding episodes from different sites. Previously, he had been investigated for recurrent bleeding episodes in different hospitals for 4 months. In our center, the review of medical history, examination findings, and laboratory results showed some important inconsistencies leading to suspicion of MCA and the mother as the perpetrator. Then he was hospitalized for close observation. During hospitalization, multiple episodes of said-to-be bleeding were reported by the mother, but active bleeding was never observed by any hospital staff. No bleeding foci were detected in the nose or ears, supporting the diagnosis of MCA. After the file was forwarded to the prosecutor\'s office, the child was taken for institutional care, and no further bleeding was observed after separation from the mother. DNA, which was obtained from a so-called nosebleed during hospitalization, was analyzed and was reported to belong to the mother, confirming the diagnosis.
CONCLUSIONS: This case report draws attention to timely diagnoses by focusing on inconsistencies in the history and clinical signs and good clinical practices for the management of MCA, with a special emphasis on collecting evidence, including DNA samples, to confirm the diagnosis and help the legal process.

Munchausen Syndrome (MS) has been widely recognized as a severe manifestation of factitious disorder, a condition where individuals intentionally fabricate or exaggerate symptoms for psychological gratification. It represents a complex diagnostic challenge due to its elusive nature and intricate relationship with various medical conditions. We present a clinical case of a 44-year-old woman observed in the context of Liaison Psychiatry, demonstrating the intricate interplay between chronic medical conditions, psychiatric factors, and the challenges in diagnosing and managing MS. The patient exhibited a history of recurrent hospitalizations, difficult-to-heal injuries, and a pronounced preference for surgical interventions. Despite diagnostic difficulties and poor therapeutic adherence, a multidisciplinary team approach involving plastic surgery, orthopedics, physical medicine, and rehabilitation, alongside Liaison Psychiatry, led to the diagnosis of MS with chronic osteomyelitis, ultimately necessitating a transtibial amputation. The case underscores the importance of early detection, a multidisciplinary approach, and the role of Liaison Psychiatry in managing MS. While early diagnosis may not alter the disease course, it can prevent unnecessary interventions and mitigate associated risks. The case also highlights the need for continuous psychiatric support and family involvement in addressing the recurrence of self-injurious behaviors. Further research is essential to enhance our understanding and develop effective treatment strategies for MS, contributing to improved diagnostic precision and overall management of this challenging psychiatric disorder.

Dermatitis artefacta (factitious dermatitis) is a dermatological disease of different types; it could appear on various parts of the body. It is associated with severe difficulties, such as psychic distress and negative feelings aroused in healthcare personnel or borderline personality disorder, and the long-term possibility of patient self-harm to create more symptoms, resulting in unnecessary medical procedures. This is a case of a 17-year-old girl who was hospitalized with a skin ulcer on her right ankle that proved to be a factitious disorder. She was experiencing severe symptoms of anxiety, such as feeling nervous, having trouble sleeping and concentrating, and an inability to control worry due to her preparation for university studies. She refused to see a mental health professional since the onset of anxiety symptoms, i.e., the last four months. Patients who present with factitious disorder deliberately create clinical signs of a somatic disease because they need warmth and attention in a medical environment. Symptoms offer no significant benefit, and the pathophysiological mechanisms are mainly psychological. The primary treatment for factitious disorder is psychotherapy while the management of the ulcer requires dermatosurgical treatment.

Factitious disorders represent deliberately fabricated dissimulation of physical and psychological signs and symptoms seeking medical attention by the patient. Usually, they are ignorant of conventional treatment and consistently change their version of signs and symptoms. Due to various changes in the version, they do not respond to the treatment. They describe their signs and symptoms as dissimulated, imaginative, and exasperated, involving any part of the body. Gingivitis artefacta is an unusual and dramatic presentation with self-inflicted physical injury to the gingival tissues. We present an extremely rare case of frontal lobe glioma causing abnormal psychology of factitious disorder resulting in self-inflected injury to gingiva in an adult male. This case also highlights the management of the dental condition of multiple recessions with coronally advanced flaps with orthodontic buttons.

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.
METHODS: 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.

We present the case of a young woman with an extensive medical history that most notably includes over 60 emergency-room visits for unfounded respiratory distress that often prompted intubations. Each presentation displays elements of deceitfulness or inappropriate demands that align with factitious disorder imposed on self. Top experts in the Consultation-Liaison field provide guidance for this commonly encountered clinical case based on their experience and review of available literature. Key teaching topics include a review of risk factors for development of deceptive syndromes, distinguishing factitious disorder from malingering and conversion disorder, and the role of a consulting psychiatrist in such cases. Patients with factitious disorder often show signs of pathologic lying, obstinance, and erratic behavior. Such attributes frequently arouse negative countertransference in providers, causing frustration and dread with continuing care, rendering psychiatric involvement. We address the unique challenges in managing factitious disorder and how to effectively collaborate with an interdisciplinary inpatient team with these cases.

We report a 31-year-old female presented with a history of recurrent skin and oral lesions for 10 years. She brought a histopathology report confirming the diagnosis of pemphigus vulgaris (PV), which was found to be faked with no patient information and lacked letterhead. Skin and oral examination only reveal multiple linear upper lip erosions. We believed the patient had a preliminary diagnosis of PV, and we asked the patient to continue her medications. Based on the conflicting history and occurrence of contradictory issues, a diagnosis of dermatitis artefacta was made. The patient improved after four sessions of dialectical therapy.

Factitious disorder (FD) is a condition in which patients fabricate evidence and produce false stories that often subject them to needless medical interventions with no clear benefits. In some instances, it can be imposed on a secondary victim often as a form of abuse. Most often, victims of a factitious disorder imposed on another (FDIA) are children or the elderly. Despite a mortality rate between 6 and 10% among victims, FDIA still remains underdiagnosed. Research on it often fails to address healthcare management initiatives, as well as the legal and ethical challenges physicians must navigate when managing it. In this report, we present a rare case of FDIA in an adult patient with a history of diabetes, substance use disorder, and schizoaffective disorder. This case highlights the importance of appropriate communication and detailed documentation when signs of FDIA are suspected. It also identifies the benefits of implementing a multidisciplinary approach when appropriate to minimize harm and improve outcomes.

Recurrent episodes of hypoglycemia are uncommon in non-diabetic patients. The workup investigation must confirm hypoglycemia and distinguish between endogenous versus exogenous hyperinsulinism. Simultaneous measurements of plasma glucose, insulin, C-peptide, and a screen for oral hypoglycemic agents should be performed. According to the results, further imaging studies may be necessary. A 43-year-old woman suffering from recurrent hypoglycemia presented to the emergency room (ER) with a hypoglycemic coma. She has had multiple episodes of documented hypoglycemia for the last 13 years. The case was initially investigated, and laboratory studies revealed endogenous hyperinsulinism. Screening for sulfonylureas, anti-insulin and anti-insulin receptor antibodies were negative. Body imaging and positron emission tomography (PET) with 68Ga-DOTANOC did not show evidence of an insulinoma. The patient was submitted to a pancreatectomy, which revealed nesidioblastosis in the histologic examination. Since then, the patient became hyperglycemic but the insulin doses were progressively reduced until new episodes of hypoglycemia recurred and the insulin was stopped. Again, inappropriately high levels of insulin were found at the time of hypoglycemic episodes. Computed tomography (CT) and PET scans did not find evidence of an insulinoma. A C-peptide was later found to be negative and insulin ampoules were found in her possession, making a diagnosis of a factitious disorder. Although rare, factious disorders are frequently overlooked and challenging to diagnose. Since they are very resource and time-consuming, self-inflicted illnesses should always be considered and ruled out beforehand.
