ABSTRACT

A 27-year old woman reported an attack by her ex-partner. According to her, he suddenly started to strangle her with his left hand, using a claw-like grip against her throat. After 30-60 seconds the victim reacted by kicking the attacker in the groin, thereby disrupting the strangulation. During the court hearing, pictures of the strangulation marks taken by the police were shown as evidence. From a forensic viewpoint, the pictures and the victim's statements did present several inconsistencies, suggesting the possibility of self-inflicted injuries. The ex-partner was found guilty. The defense appealed against the sentence and demanded a thorough forensic expertise on the origin of the strangulation marks. To identify the possible origin of the strangulation marks considering the victim's statements and the presented strangulation marks, a reconstructive study with 26 participants (25 attackers, 1 victim) was carried out. In the study, the expected strangulation marks did show a vertical, C-shaped pattern on the study subject's neck and throat, while the wounds on the victim's neck were aligned horizontally on the right side of the neck. These results show that the strangulation marks on the neck of the victim did not correspond to the claw-like grip at the throat as described by the victim. In this light, the possibility of self-inflicted injuries is discussed.

ABSTRACT

Prader-Willi syndrome (PWS) is a rare neurodevelopmental disorder caused by lack of the paternal copy of maternally imprinted, paternally expressed genes at the chromosome 15q11-13 region. In most cases, it is caused by a paternal deletion or a maternal disomy of chromosome 15. Behavioral problems with temper outbursts are common and often combined with physical aggressiveness and self-injury. They are the most frequent cause for a reduced quality of life in adulthood and represent a serious challenge for the individual and those surrounding the individual in everyday life. Until now, no promising pharmaceutical treatment option has been established, and only a few case reports on treatment with selective serotonin reuptake inhibitors (SSRIs) have been reported. In this case series, we investigated the effect of the SSRI sertraline in 14 individuals with PWS frequently showing severe temper outbursts with aggressiveness and self-injuries. After 6 months of treatment with sertraline, 13 of 14 patients (92.6%) either no longer displayed temper outbursts or showed a significant decrease in frequency and severity of temper outbursts. In one case, treatment was stopped due to severe sleep abnormalities. We conclude that sertraline is a promising and safe treatment option for severe temper outbursts in patients with PWS.

ABSTRACT

Autism Spectrum Disorder (ASD) is a heterogeneous disorder that is often accompanied with many co-morbidities. Recent genetic studies have identified various pathways from hundreds of candidate risk genes with varying levels of association to ASD. However, it is unknown which pathways are specific to the core symptoms or which are shared by the co-morbidities. We hypothesised that critical ASD candidates should appear widely across different scoring systems, and that comorbidity pathways should be constituted by genes expressed in the relevant tissues. We analysed the Simons Foundation for Autism Research Initiative (SFARI) database and four independently published scoring systems and identified 292 overlapping genes. We examined their mRNA expression using the Genotype-Tissue Expression (GTEx) database and validated protein expression levels using the human protein atlas (HPA) dataset. This led to clustering of the overlapping ASD genes into 2 groups; one with 91 genes primarily expressed in the central nervous system (CNS geneset) and another with 201 genes expressed in both CNS and peripheral tissues (CNS+PT geneset). Bioinformatic analyses showed a high enrichment of CNS development and synaptic transmission in the CNS geneset, and an enrichment of synapse, chromatin remodelling, gene regulation and endocrine signalling in the CNS+PT geneset. Calcium signalling and the glutamatergic synapse were found to be highly interconnected among pathways in the combined geneset. Our analyses demonstrate that 2/3 of ASD genes are expressed beyond the brain, which may impact peripheral function and involve in ASD co-morbidities, and relevant pathways may be explored for the treatment of ASD co-morbidities.

ABSTRACT

Self-harm and mental health are inter-related issues that substantially contribute to the global burden of disease. However, measurement of these issues at the population level is problematic. Statistics on suicide can be captured in national cause of death data collected as part of the coroner's review process, however, there is a significant time-lag in the availability of such data, and by definition, these sources do not include non-fatal incidents. Although survey, emergency department, and hospitalisation data present alternative information sources to measure self-harm, such data do not include the richness of information available at the point of incident. This paper describes the mental health and self-harm modules within the National Ambulance Surveillance System (NASS), a unique Australian system for monitoring and mapping mental health and self-harm. Data are sourced from paramedic electronic patient care records provided by Australian state and territory-based ambulance services. A team of specialised research assistants use a purpose-built system to manually scrutinise and code these records. Specific details of each incident are coded, including mental health symptoms and relevant risk indicators, as well as the type, intent, and method of self-harm. NASS provides almost 90 output variables related to self-harm (i.e., type of behaviour, self-injurious intent, and method) and mental health (e.g., mental health symptoms) in the 24 hours preceding each attendance, as well as demographics, temporal and geospatial characteristics, clinical outcomes, co-occurring substance use, and self-reported medical and psychiatric history. NASS provides internationally unique data on self-harm and mental health, with direct implications for translational research, public policy, and clinical practice. This methodology could be replicated in other countries with universal ambulance service provision to inform health policy and service planning.

ABSTRACT

BACKGROUND: Non-suicidal self-injury (NSSI) and suicidality are common reasons for child and adolescent psychiatric emergencies. We aimed to investigate the incidence of pediatric emergency department (PED) utilization for psychiatric problems in children and adolescents and to identify demographic and clinical characteristics of youths who visited the PED for suicide attempt (SA) and/or NSSI. METHODS: The medical records of children and adolescents who visited the PED for psychiatric problems from January 2015 to November 2019 were reviewed retrospectively. Demographic and clinical variables including psychiatric disorders were collected. We compared the characteristics of youths who presented to the PED for SA and/or NSSI with those of youths without SA or NSSI. Student's t-test, χ² test, and multivariate logistic regression were used for statistical analysis. RESULTS: During 59 months of observation, 194 youths visited the PED and the number of total PED visits was 336. Among them, 46 youths (23.7%) visited the PED for SA and/or NSSI at least once, and the number of visits was 91 (27.1% of PED visits). Youths with SA and/or NSSI were older (P = 0.001) and more likely to be a girl (P = 0.005) and to report parental absence (P = 0.023). Bipolar and related disorders (P = 0.032) and depressive disorders (P = 0.004) were more common in youths with SA and/or NSSI, while schizophrenia spectrum and other psychotic disorders (P = 0.030) and somatic symptom and related disorders (P = 0.007) were more common in those without SA and NSSI. After adjusting for age, sex, and parental marital status, bipolar and related disorders (odds ratio [OR], 6.72), depressive disorders (OR, 9.59), and somatic symptom and related disorders (OR, 0.12) were significantly associated with SA and/or NSSI. Youths with SA and/or NSSI also stayed longer in the PED (P = 0.007). CONCLUSION: SA and NSSI are one of the main reasons for child and adolescent admittance to psychiatric services in the PED and are associated with psychiatric comorbidities. An appropriate risk assessment for suicidality and self-injury and proper management and referral to mental health services at the PED are of the utmost importance.

ABSTRACT

The means by which people self-harm are diverse and so are the motives that drive them. They are intended for personal gain which may be psychological, legal or material. Fabricated injuries may be self-inflicted or permitted by others. We present three cases of fabricated injuries over the shoulder and upper limbs both alleging assault with a firearm. In all the cases meticulous examination elicited suspicion on how these were caused. Meticulous examination is essential to differentiate true from false accusations so that no innocent person is punished.

ABSTRACT

It has been known that infants less than 1 year develop cerebral white matter (WM) lacerations associated with head trauma, however, there has been no report of similar WM lesions over 1 year. We report three teenage boys (11, 12, and 18 years at final MRI studies) with acquired WM lacerations associated with recurrent head trauma who developed neurologic symptoms such as spastic paralysis, afebrile convulsions, and cognitive impairment. Two of them (patients 1 and 2) were given a diagnosis of autism spectrum disorder and had a history of repeated severe self-inflicted head trauma from preschool age. Patient 3, who practiced karate and boxing from preschool age, showed gradual declining intellectual ability. Brain MRI of the three patients revealed severe lacerations in the bilateral cerebral WM. Previous neuroimaging showed no WM lacerations at 4 and 5 years in patients 1 and 2, or mild WM lacerations at 17 years in patient 3, indicating the WM lacerations could have been acquired in childhood. It is suggested that repetition of head trauma in children can cause cerebral WM lacerations and brain dysfunction.

ABSTRACT

INTRODUCTION: Excoriation (skin picking) disorder is included in the DSM-5 in the obsessive compulsive and related disorders category. It is defined as the recurrent urge to touch, scratch, scrape, scrub, rub, squeeze, bite or dig in the skin, leading to skin lesions. It is a rare disorder (1.4-5.4% of the population) and occurs mainly in women. CASE REPORT: this article reports the case of a 31-year-old female patient, initially assessed by dermatology and orthopaedics for the presence of infected ulcerated lesions on her lower limbs, with other superficial lesions from scratching on her chest, arms, forearms, back and head. The patient also reported symptoms of anxiety, so was assessed by consultation-liaison psychiatry. DISCUSSION: skin picking, normal behaviour in mammals, becomes pathological from a psychiatric point of view when it is repetitive and persistent, as in the case of excoriation disorder. In view of the reported relationship with the obsessive-compulsive spectrum, use of selective serotonin reuptake inhibitors and cognitive behavioural therapy are recommended.

ABSTRACT

Self-inflicted injury (SII) in adolescence is a serious public health concern that portends prospective vulnerability to internalizing and externalizing psychopathology, borderline personality development, suicide attempts, and suicide. To date, however, our understanding of neurobiological vulnerabilities to SII is limited. Behaviorally, affect dysregulation is common among those who self-injure. This suggests ineffective cortical modulation of emotion, as observed among adults with borderline personality disorder. In borderline samples, structural and functional abnormalities are observed in several frontal regions that subserve emotion regulation (e.g., anterior cingulate, insula, dorsolateral prefrontal cortex). However, no volumetric analyses of cortical brain regions have been conducted among self-injuring adolescents. We used voxel-based morphometry to compare cortical gray matter volumes between self-injuring adolescent girls, ages 13-19 years (n = 20), and controls (n = 20). Whole-brain analyses revealed reduced gray matter volumes among self-injurers in the insular cortex bilaterally, and in the right inferior frontal gyrus, an adjacent neural structure also implicated in emotion and self-regulation. Insular and inferior frontal gyrus gray matter volumes correlated inversely with self-reported emotion dysregulation, over-and-above effects of psychopathology. Findings are consistent with an emotion dysregulation construal of SII, and indicate structural abnormalities in some but not all cortical brain regions implicated in borderline personality disorder among adults.

ABSTRACT

BACKGROUND: Self-injurious behaviour (SIB) can be classified as intentional, direct injuring of body tissue usually without suicidal intent. In its non-suicidal form it is commonly seen as a clinical sign of borderline personality disorder, autism, PTSD, depression, and anxiety affecting a wide range of ages and conditions. In rhesus macaques SIB is most commonly manifested through hair plucking, self-biting, self-hitting, and head banging. SIB in the form of self-biting is observed in approximately 5-15% of individually housed monkeys. Recently, glial cells are becoming recognised as key players in regulating behaviours. METHOD: The goal of this study was to determine the role of glial activation, including astrocytes, in macaques that had displayed SIB. To this end, we performed immunohistochemistry and next generation sequence of brain tissues from rhesus macaques with SIB. RESULTS: Our studies showed increased vimentin, but not nestin, expression on astrocytes of macaques displaying SIB. Initial RNA Seq analyses indicate activation of pathways involved in tissue remodelling, neuroinflammation and cAMP signalling. CONCLUSIONS: Glia are most probably activated in primates with self-injury, and are therefore potential novel targets for therapeutics.

ABSTRACT

BACKGROUND: Non-suicidal self-injury (NSSI) is a frequent phenomenon in adolescents and is closely related to eventual suicide. Although the effect of air pollution on various diseases has been extensively investigated, no studies examined its effect on NSSI in young students. OBJECTIVES: We investigated the effect of air pollution on NSSI in Chinese students. METHODS: We investigated the incidence of NSSI in the past 12 months in 54 923 Chinese students with an anonymous questionnaire. We assessed the air pollution exposure of each student by the air quality matched with their schools, which were calculated by the inverse distance weighting method from the environmental monitoring data. We discussed the association between ambient air pollutants and the incidence of NSSI using generalized additive mixed models. RESULTS: A 10 µg/m3 increase in the annual moving average concentration of particulate matter with diameters less than 2.5 µm (PM2.5) and ozone (O3) was associated with a 13.9 percent and a 10.5 percent increase in the odds ratio (OR) of NSSI, respectively. In addition, a 0.1 mg/m3 increase in the annual moving average concentration of carbon monoxide (CO) was associated with a 4.8 percent increase in the OR of NSSI. NO2 and SO2 were not related to NSSI. CO and O3 show non-linear effects on NSSI. Male students in high school are the most s to the effects of PM2.5 on NSSI. CONCLUSIONS: Our study suggests that increases in PM2.5, O3 and CO may increase the incidence of NSSI among adolescent students.

ABSTRACT

Despite accelerating interest in the impact of the internet on suicidal behaviour, empirical work has not captured detailed narratives from those who engaged in suicide-related internet use. This study explored the suicide-related online behaviour of two contrasting samples of distressed users, focusing on their purpose, methods and the main content viewed. In-depth interviews were conducted in the UK between 2014-2016 with i) young people in the community; and ii) self-harm patients presenting to hospital emergency departments. Data were analysed using methods of constant comparison. Suicide-related internet use varied according to the severity of suicidal feelings. In the young people sample, where severity was lower, use was characterised by disorganised browsing without clear purpose. A range of content was 'stumbled upon' including information about suicide methods. They also pursued opportunities to interact with others and explore online help. Self-harm patients were a higher severity group with a history of suicidal behaviour. Their use was purposeful and strategic, focused around 'researching' suicide methods to maximise effectiveness. They made specific choices about content viewed; many consulting factual content in preference to user generated accounts, while help content and communication was avoided. Findings indicate further action is necessary to improve online safety. Also, novel online help approaches are needed to engage individuals experiencing suicidal crisis. Awareness of the nature of suicide-related internet use and how this may reflect the status of an individual's suicidal thinking could be beneficial to clinicians to promote safety and indicate risk.

ABSTRACT

Factitious dermatitis (FD) (dermatitis artefacta) is rare and often difficult to diagnose because of conflicting history and nonspecific clinical and histologic findings. It can present with varied clinical features including geometric ulcers, erosions, and less commonly bullae secondary to external trauma from chemicals, electric burns, heat, and suction. Herein, we describe a case of bullous FD due to thermal burn with histologic features demonstrating overlap with fixed drug eruption. Histopathology demonstrated a subepidermal blister with epidermal necrosis along with pigment incontinence and dermal eosinophils and neutrophils. Although these features, and the clinician's impression, were suggestive of fixed drug eruption, several morphologic findings allowed accurate diagnosis of FD: sharp demarcation of necrotic keratinocytes from adjacent uninvolved epidermis, elongated keratinocytes reminiscent of thermal or electrical artifact, and multinucleated keratinocytes. Although FD is often considered a diagnosis of exclusion, these clues may help dermatopathologists distinguish this entity from inflammatory dermatoses.

ABSTRACT

Given the potential significance of mutilation of the external genitalia in medicolegal fatalities, a review of the literature was undertaken to identify subcategories. Such mutilations may have been sustained sometime before death, around the time of death, or after death. The most common type of ante mortem genital mutilations involves cultural practices such as male circumcision. Less common male mutilations such as subincisions are tribally based. Female genital mutilation is found particularly in African, Middle Eastern, or Asian populations. Self-inflicted genital injuries are most common in males and may be related to attempts at suicide, or to self-harming practices. The latter have a strong association with psychiatric illnesses. Postmortem injuries may arise from animal predation or deliberate mutilation of a corpse. The latter may be associated with ante mortem genital injuries in sadistic homicides. The range of possible causes of genital mutilations in forensic cases necessitates extremely careful evaluation.

ABSTRACT

OBJECTIVE: The objective of this study is to present a case series of nonmissile penetrating (NMP) injuries and to establish a workflow for an uncommon mechanism of traumatic head injury through the analysis of each case, classification of the type of lesion, management, and outcome score at follow-up. METHODS: From January 1991 to December 2008, 36,000 patients presenting with traumatic brain injury (TBI) were admitted in the Department of Neurosurgery, Hospital Antônio Targino, Campina Grande-PB, Brazil. From these patients, 11 presenting with lesions caused by NMP objects were selected. RESULTS: Among the 11 patients, 9 were men and 2 were women. Their ages ranged from 7 to 74 years old (mean age ± SD, 29.1 ± 22.99 years). All patients underwent neuroradiologic evaluation. The entry point was classified as natural (orbit) or artificial (skull transfixation), and we also divided the patients presenting with secondary parenchymal or vascular damage from those presenting with only lesions caused by the primary penetration into the cranium and meninges. All patients were neurosurgically treated with removal of the foreign body through craniotomy, except the patient whose object (pen) was removed without craniotomy with local anesthesia. Glasgow Coma Scale (GCS) score on admission was a statistically significant factor on prognosis, and any patient who presented with a GCS score of 15 evolved satisfactorily, and there were no deaths in this group of patients (P = 0.04). CONCLUSIONS: TBIs caused by NMP objects are unusual and caused by aggression, self-inflicted harm (in the case of psychiatric patients), and accident. The foreign body may enter into the skull through a natural hole (orbit, nose, mouth, or ear) or crosses the skull, causing a fracture and creating an artificial hole. Preoperative neuroradiologic assessment is paramount for the correct neurosurgical approach. The main prognostic factor for these patients is the GCS score at admission.
