Self-Amputation in Patient with Body Integrity Dysphoria in Comorbidity with Gender Dysphoria: A Case Report.

We present a rare, atypical case of a 24-year-old transgender male (assigned as a female at birth) admitted to the hospital after the planned self-amputation of his left hand. The patient described his motivation for this self-amputation as coming from deep-rooted and persistent feelings that this hand was not a part of his body. He identified himself as having, according to internet peer group definition, body integrity identity disorder. This condition is now referred to as body integrity dysphoria (BID). This patient was later diagnosed as having gender dysphoria and other conditions, including bipolar disorder and gaming disorder. The follow-up 2 years after self-amputation is presented, during which, despite antipsychotic and antidepressant treatment, the symptoms of BID remained unchanged and the high variability of other psychopathology was observed. This is an unusual case of BID simply because several other comorbidities are presented. Like many other rare clinical situations, this case also presents a particular challenge to our understanding of the dynamics and interrelationships between comorbidities, raising concerns and questions.

Self-Amputation of the Extra Digit in a Fetus with Polydactyly: First Ultrasound Demonstration.

We herein report the first ultrasound evidence of the self-amputation of an extra digit in case of fetal polydactyly. The prenatal evidence of fetal polydactyly is not always followed by postnatal confirmation. This is not always due to ultrasound misdiagnosis, but often to an in utero self-amputation phenomenon. We demonstrate that there is the detachment of part of the digit, leading to the evidence of a neonatal bump on the site of the prenatal extra digit. This demonstration has been possible by the direct visualization of the remnant by ultrasound.

[Self-inflicted genital injury].

Self-inflicted injury to external genitalia in men is an uncommon type of trauma. The international and domestic literature report isolated cases of injury to the external genitalia, caused by a patient intending to harm himself. This type of injury often occurs in patients with mental disorders. The authors describe their own clinical observations of rare types of self-inflicted genital injuries in patients without a history of mental disorders. During the period from 2012 to 2015, 4 patients with self-inflicted genital injuries were admitted to the hospital. There was a penile self-amputation, self-orchiectomy, penile rupture, and foreskin cut wound. Despite the sufficient public awareness and availability of urological care in a large industrial city, cases of self-inflicted genital injury occur. In addition to medical care, such cases warrant psychological and possibly psychiatric counseling.

[Self-amputation of the penis treated immediately: Case report and review of the literature]. / Auto-amputation de verge traitée par réparation d'emblée: à propos d'un cas et revue de la littérature.

Self-amputation of the penis treated immediately: case report and review of the literature. Self-amputation of the penis is rare in urological practice. It occurs more often in a context psychotic disease. It can also be secondary to alcohol or drugs abuse. Treatment and care vary according on the severity of the injury, the delay of consultation and the patient's mental state. The authors report a case of self-amputation of the penis in an alcoholic context. The authors analyze the etiological and urological aspects of this trauma.

Eco-mechanics of lamellar autotomy in larval damselflies.

In larval damselflies, the self-amputation (autotomy) of the caudal lamellae permits escape from predatory larval dragonflies. Lamellar joint size declines among populations with increasing risk of dragonfly predation, but the breaking force required for autotomy and the biomechanical factors that influence breaking force are unknown. If autotomy enhances survival in larval damselflies, then predation by larval dragonflies should select for joints that require less force to break. We test this adaptive hypothesis by evaluating whether breaking force is negatively related to local predation risk from larval dragonflies. We also test a cuticle structure hypothesis, which predicts that breaking force is positively related to joint size and to joint cuticle thickness because of a structural support relationship between joint and lamella. The peak force necessary for lamellar autotomy was assessed on individual larval Enallagma damselflies collected from populations that varied in risk of predation. Easier lamellar autotomy occurred in larvae from sites with higher predation risk because damselflies from fishless ponds (where predatory larval dragonflies are likely more abundant) had lower breaking forces than those from ponds with fish (where larval dragonfly predation is likely reduced). Furthermore, breaking force was a positive function of joint size and also of total cuticle cross-sectional area after controlling for joint size. This suggests that autotomy may evolve in larval damselflies under selection from small grasping predators such as larval dragonflies by favouring smaller joint size or reduced cuticle area of lamellar joints.

Advanced penile cancer with multiple metastases and self-amputation of penis: A rare case report.

Penile cancer is a rare malignancy with poor prognosis. Advanced penile cancer that invades the penile shaft and causes urinary retention could be rarely seen. We reported a 72-year-old male suffered from advanced penile cancer with penile self-amputation and acute urinary retention. We reckoned the self-amputation of penis as a new sign of advanced penile cancer.

Snow flies self-amputate freezing limbs to sustain behavior at sub-zero temperatures.

Temperature profoundly impacts all living creatures. In spite of the thermodynamic constraints on biology, some animals have evolved to live and move in extremely cold environments. Here, we investigate behavioral mechanisms of cold tolerance in the snow fly (Chionea spp.), a flightless crane fly that is active throughout the winter in boreal and alpine environments of the northern hemisphere. Using thermal imaging, we show that adult snow flies maintain the ability to walk down to an average body temperature of -7°C. At this supercooling limit, ice crystallization occurs within the snow fly's hemolymph and rapidly spreads throughout the body, resulting in death. However, we discovered that snow flies frequently survive freezing by rapidly amputating legs before ice crystallization can spread to their vital organs. Self-amputation of freezing limbs is a last-ditch tactic to prolong survival in frigid conditions that few animals can endure. Understanding the extreme physiology and behavior of snow insects holds particular significance at this moment when their alpine habitats are rapidly changing due to anthropogenic climate change. VIDEO ABSTRACT.

Self-Inflicted Total Amputation of the External Genitalia as a Psychological Repercussion of the COVID-19 Pandemic: A Case Report.

During the coronavirus disease 2019 (COVID-19) pandemic, mandatory quarantine has interrupted everyday social life, leaving many individuals feeling confined and lonely, with increased rates of suicide and suicidal behavior. Genital self-mutilation (GSM) is a rare phenomenon that typically occurs in the context of severe mental illness. The following case report describes the first case of total self-inflicted genital amputation in a healthy man who had no prior history of mental or medical conditions. This case poses challenges for psychiatric diagnosis and treatment. We report a case of a 52-year-old male with no significant medical and psychiatric history who was admitted to a tertiary care hospital after attempting suicide by self-inflecting a total amputation of his external genitalia due to fear of COVID-19 infection. The diathesis-stress linked with the tribulations of the current pandemic was highlighted as well as other possible contributory factors and psychopathology behind his clinical presentation.

Penile self-amputation due to cannabis-induced psychosis: a case report.

BACKGROUND: In recent decades, cannabis has been widely used around the world for medical and recreational purposes, both legally and illegally. Aside from its therapeutic benefits, cannabis exhibits many adverse effects. Psychosis is one of the potentially harmful effects of cannabis. CASE PRESENTATION: A 23-year-old Thai man, who reported cannabis use for 2 years and discontinued for 3 months, restarted smoking two bongs (2 g equivalence) of cannabis. Two hours later, he had a penile erection, felt a severe persistent sharp pain in his penis, and reported that his glans looked distorted. Intending to eradicate the pain, he decided to trim the penile skin several times and completely amputated his penis himself using scissors. Cannabis-induced psychosis was diagnosed because symptoms began after cannabis use, without evidence of other substance abuse. To confirm the cannabis exposure, his urine immunoassay was positive for delta-9-tetrahydrocannabinol (Δ9-THC). The distal penis was deemed too dirty and fragile for reconstruction. Bleeding was controlled, penile stump irrigated and debrided, and scrotal urethrostomy was performed by a urologist. After admission and cannabis discontinuation, his delusion and hallucination subsided. CONCLUSIONS: Cannabis-induced psychosis is an adverse effect of cannabis, which may lead to impaired judgement unexpected self-harm. A multidisciplinary team approach, including a primary care physician, an emergency physician, a urologist, and a psychiatrist, is essential when dealing with a patient with cannabis-induced psychosis and a urogenital injury.

Presentation and resolution of gender dysphoria as a positive symptom in a young schizophrenic man who presented with self-emasculation: Frontiers of bioethics, psychiatry, and microsurgical genital reconstruction.

Gender dysphoria can present as a positive symptom of schizophrenia. Completion of gender affirmation surgeries should not occur as a result of male genital self-mutilation via a deferral of emergent surgical reconstruction. Instead, gender affirmation should be considered after a full workup and assessment for resolution of any acute psychosis.

Self-amputation of the Upper Extremity: A Case Report and Review of the Literature.

Indications for upper-extremity replantation include wrist-level and wrist-proximal amputations, due to the devastating loss of function incurred from these severe injuries. Decisions regarding replantation must be made expeditiously at these proximal levels in an effort to minimize ischemia time. This decision-making process becomes more complicated when a patient presents following intentional self-amputation of an extremity, especially in the setting of an associated mood disorder, psychiatric illness, and/or frank psychosis. A case report is presented involving a 28-year-old right-hand dominant male with untreated depression and recent suicidal ideation who sustained a complete left forearm amputation (distal-third forearm-level) from a self-inflicted circular saw injury. We conducted a PubMed literature search of other reported cases of intentional self-amputations of the hand and upper extremity. The patient underwent replantation of the left upper extremity. At six years postoperatively, the patient was extremely satisfied with the appearance and function of the replanted extremity. Dash score was 5.8 with a Chen Grade 1 (excellent) functional recovery. A literature search identified 16 cases of self-inflicted upper extremity amputation. One patient died at the scene. 87% (13/15) of patients presenting to the hospital were diagnosed with a psychiatric disorder (depression n = 6, bipolar n = 2, and schizophrenia n = 5). 67% (10/15) of these patients were also diagnosed with psychosis. Ten patients underwent replantation (nine at hand/wrist level and one at forearm level), all of which were viable postoperatively. Detailed functional outcome data were not reported in any of the cases. Four patients (40%) were pleased or satisfied with the outcome, but subjective outcomes were not reported for the other six patients. Intentional self-amputation of the hand/upper extremity is an extreme and uncommon act, often presenting with complex psychiatric issues. Although replantation is technically feasible in this patient population, long-term subjective and objective functional outcomes are largely unknown. Future study of this unique group of patients is needed to better assess patient-reported outcomes and functional outcomes of replantation, which could help guide decision making at the time of initial injury.

Is hypogonadism the cause of penile self-amputation in a patient with prior testes self-mutilation?

INTRODUCTION: This paper presents a rare event of genital self-mutilation and few cases are reported in the literature. CASE DESCRIPTION: We report on a patient who performed partial self-penectomy 18 months after bilateral testicular amputation, as a form of self-mutilation. CONCLUSIONS: The main hypotheses to explain the recurrence of self-mutilation would be hypogonadism.

Male genital self-mutilation: a systematic review of psychiatric disorders and psychosocial factors.

OBJECTIVE: To identify psychiatric diagnoses and psychosocial factors associated with intentional male genital self-mutilation (GSM) of specific injury subtypes. METHODS: A search of MEDLINE, EMBASE, PsycINFO, PubMed, Web of Science and CINAHL for cases of GSM was conducted until December 2015, based on GSM and related terms. Cases were examined for injury subtype, psychiatric diagnosis and psychosocial factors. Chi-square analyses were employed to determine differences in frequency of such factors across injury subtypes. RESULTS: Data were obtained from 173 cases: genital mutilation (n=21), penile amputation (n=62), castration (n=56) and combined amputation/castration (n=34). Common psychiatric disorders included schizophrenia spectrum (49%), substance use (18.5%), personality (15.9%) and gender dysphoric disorders (15.3%). Chi-square analyses revealed that schizophrenia spectrum disorders occurred significantly more often among auto-amputates as compared with self-castrators or mutilators. Gender dysphoria occurred significantly more often among self-castrators than auto-amputates. No significant differences emerged regarding psychosocial factors across GSM subtypes. However, associations were observed between psychosocial factors and psychiatric diagnoses. Although altogether not commonly reported, experiential factors were reported in 82% of psychotic individuals. Treatment inaccessibility was noted among 71% of gender dysphorics engaging in auto-castration. CONCLUSION: Clinicians must consider the diverse range of psychiatric disorders and psychosocial factors underlying GSM.

Self-Amputation in Two Non-Psychotic Patients.

Self-amputation, the extreme form of self-mutilation, is uncommon. The vast majority of cases are associated with psychosis, with a small number being assigned the controversial diagnosis of body identity integrity disorder. In this article, we report two cases of non-psychotic self-amputation and their similarities with a view to highlighting the risk factors and formulating an appropriate management plan.

[Report of a case of penile self-amputation]. / A propósito de un caso de autoamputación peneana.

INTRODUCTION: Motivated by a clinic case, this report introduces some issues related with genital self-amputation in terms of descriptions, epidemiological and clinical issues. METHODOLOGY: Case report describing a clinic case of genital self-amputation. The description is followed by a discussion based on the information available in the scientific literature. A man, 32 years old, with no history of mental disorder, who amputates his penis with a cutting object after quarreling with his mate for infidelity reasons. RESULTS: Several characteristics imply risk factors for genital self-mutilation, such as gender identity disorders, rejection to male genitals, guilt feelings related to sexual activity and a history of previous self-injuries. More common diagnoses include schizophrenia and affective disorders followed by disorders induced by psychoactive substances. CONCLUSION: Genital self-amputation is not a frequent situation and has been under-recorded; however, bearing in mind the high association with psychopathology and recurrence reported in worldwide literature, it is necessary to carry out a proper study and following up of patients exhibiting this conduct.

Abordagem cirúrgica de faixas constritivas em Síndrome de Vohwinkel / Surgical correction of constrictive bands in Vohwinkel syndrome

A Síndrome de Vohwinkel ou ceratodermia hereditária mutilante é uma ceratodermia palmoplantar rara, que se manifesta na infância e se torna mais evidente nas fases de adolescência e idade adulta. Doença de herança preferencialmente autossômica dominante, acomete mais mulheres e caucasianos. A hiperceratose palmoplantar difusa, com aparência de favo de mel; as faixas constritivas digitais conhecidas como pseudoainhum, e as placas ceratósicas em forma de estrela-do-mar no dorso de mãos e pés, podendo acometer cotovelos e joelhos, são os achados clínicos característicos da Síndrome. O presente trabalho trata de um relato de caso de uma paciente com Síndrome de Vohwinkel e a terapêutica cirúrgica realizada nas faixas constritivas.

Vohwinkel syndrome, also known as hereditary mutilating keratoderma, is a rare palmoplantar keratoderma that manifests in childhood and becomes more evident in adolescence and adulthood. This preferential autosomal dominant disease affects more women and Caucasians. Its clinical features are diffuse palmoplantar keratoderma with the appearance of honeycomblike constricting rings in the fingers and toes known as pseudo-ainhum, and starfish-shaped keratotic plaques on the dorsal aspect of the hands and feet that can affect the elbows and knees. The present report describes a case report of a patient with Vohwinkel syndrome and surgical correction of the constrictive bands.
