Ask Me! self-reported features of adolescents experiencing neglect or emotional maltreatment: a rapid systematic review.

BACKGROUND: Neglect is often overlooked in adolescence, due in part to assumptions about autonomy and misinterpretation of behaviors being part of normal adolescent development. Emotional maltreatment (abuse or neglect) has a damaging effect throughout the lifespan, but is rarely recognized amongst adolescents. Our review aims to identify features that adolescents experiencing neglect and/ or emotional maltreatment report. METHOD: A rapid review methodology searched 8 databases (1990-2014), supplemented by hand searching journals, and references, identifying 2,568 abstracts. Two independent reviews were undertaken of 279 articles, by trained reviewers, using standardised critical appraisal. Eligible studies: primary studies of children aged 13-17 years, with substantiated neglect and/ or emotional maltreatment, containing self-reported features. RESULTS: 19 publications from 13 studies were included, demonstrating associations between both neglect and emotional maltreatment with internalising features (9 studies) including depression, post traumatic symptomatology and anxiety; emotional maltreatment was associated with suicidal ideation, while neglect was not (1 study); neglect was associated with alcohol related problems (3 studies), substance misuse (2 studies), delinquency for boys (1 study), teenage pregnancy (1 study), and general victimization for girls (1 study), while emotionally maltreated girls reported more externalising symptoms (1 study). Dating violence victimization was associated with neglect and emotional maltreatment (2 studies), while emotional abuse of boys, but not neglect, was associated with dating violence perpetration (1 study), and neither neglect nor emotional maltreatment had an association with low self-esteem (2 studies). Neither neglect nor emotional maltreatment had an effect on school performance (1 study), but neglected boys showed greater school engagement than neglected girls (1 study). CONCLUSIONS: If asked, neglected or emotionally maltreated adolescents describe significant difficulties with their mental health, social relationships, and alcohol or substance misuse. Practitioners working with youths who exhibit these features should recognize the detrimental impact of maltreatment at this developmental stage, and identify whether maltreatment is a contributory factor that should be addressed.

A systematic review of the emotional, behavioural and cognitive features exhibited by school-aged children experiencing neglect or emotional abuse.

BACKGROUND: Interventions to minimize the long-term consequences of neglect or emotional abuse rely on prompt identification of these children. This systematic review of world literature (1947-2012) identifies features that children aged 5-14 years experiencing neglect or emotional abuse, as opposed to physical or sexual abuse, may exhibit. METHODS: Searching 18 databases, utilizing over 100 keywords, supplemented by hand searching, 13,210 articles were identified and 111 underwent full critical appraisal by two independent trained reviewers. RESULTS: The 30 included studies highlighted behavioural features (15 studies), externalizing features being the most prominent (8/9 studies) and internalizing features noted in 4/6 studies. Four studies identified attention deficit hyperactivity disorder (ADHD) associated features: impulsivity, inattention or hyperactivity. Child difficulties in initiating or developing friendships were noted in seven studies. Of 13 studies addressing emotional well-being, three highlighted low self-esteem, with a perception of external control (1), or depression (6) including suicidality (1). A negative internal working model of the mother increased the likelihood of depression (1). In assessing cognition or academic performance, lower general intelligence (3/4) and reduced literacy and numeracy (2) were reported, but no observable effect on memory (3). CONCLUSIONS: School-aged children presenting with poor academic performance, ADHD symptomatology or abnormal behaviours warrant assessment of neglect or emotional abuse as a potential underlying cause.

A systematic review of abusive visceral injuries in childhood--their range and recognition.

OBJECTIVES: To define what abusive visceral injuries occur, including their clinical features and the value of screening tests for abdominal injury among abused children. METHODS: We searched 12 databases, with snowballing techniques, for the period 1950-2011, with all identified studies undergoing two independent reviews by trained reviewers, drawn from pediatrics, radiology, pediatric surgery and pathology. Of 5802 studies identified, 188 were reviewed. We included studies of children aged 0-18, with confirmed abusive etiology, whose injury was defined by computed tomography, contrast studies or at surgery/post mortem. We excluded injuries due to sexual abuse, or those exclusively addressing management or outcome. RESULTS: Of 88 included studies (64 addressing abdominal injuries), only five were comparative. Every organ in the body has been injured, intra-thoracic injuries were commoner in those aged less than five years. Children with abusive abdominal injuries were younger (2.5-3.7 years vs. 7.6-10.3 years) than accidentally injured children. Duodenal injuries were commonly recorded in abused children, particularly involving the third or fourth part, and were not reported in accidentally injured children less than four years old. Liver and pancreatic injuries were frequently recorded, with potential pancreatic pseudocyst formation. Abdominal bruising was absent in up to 80% of those with abdominal injuries, and co-existent injuries included fractures, burns and head injury. Post mortem studies revealed that a number of the children had sustained previous, unrecognized, abdominal injuries. The mortality from abusive abdominal injuries was significantly higher than accidental injuries (53% vs. 21%). Only three studies addressed screening for abdominal injury among abused children, and were unsuitable for meta-analysis due to lack of standardized investigations, in particular those with 'negative' screening tests were not consistently investigated. CONCLUSIONS: Visceral injuries may affect any organ of the body, predominantly abdominal viscera. A non-motor vehicle related duodenal trauma in a child aged

Retinal haemorrhages and related findings in abusive and non-abusive head trauma: a systematic review.

AIM: To report the retinal signs that distinguish abusive head trauma (AHT) from non-abusive head trauma (nAHT). METHODS: A systematic review of literature, 1950-2009, was conducted with standardised critical appraisal. Inclusion criteria were a strict confirmation of the aetiology, children aged <11 years and details of an examination conducted by an ophthalmologist. Post mortem data, organic disease of eye, and inadequate examinations were excluded. A multivariate logistic regression analysis was conducted to determine odds ratios (OR) and probabilities for AHT. RESULTS: Of the 62 included studies, 13 provided prevalence data (998 children, 504 AHT). Overall, retinal haemorrhages (RH) were found in 78% of AHT vs 5% of nAHT. In a child with head trauma and RH, the OR that this is AHT is 14.7 (95% confidence intervals 6.39, 33.62) and the probability of abuse is 91%. Where recorded, RH were bilateral in 83% of AHT compared with 8.3% in nAHT. RH were numerous in AHT, and few in nAHT located in the posterior pole, with only 10% extending to periphery. True prevalence of additional features, for example, retinal folds, could not be determined. CONCLUSIONS: Our systematic review confirms that although certain patterns of RH were far commoner in AHT, namely large numbers of RH in both the eyes, present in all layers of the retina, and extension into the periphery, there was no retinal sign that was unique to abusive injury. RH are rare in accidental trauma and, when present, are predominantly unilateral, few in number and in the posterior pole.

Neuroimaging: what neuroradiological features distinguish abusive from non-abusive head trauma? A systematic review.

OBJECTIVES: To identify the evidence base behind the neuroradiological features that differentiate abusive head trauma (AHT) from non-abusive head trauma (nAHT). DESIGN: Systematic review. SETTING: Literature search of 14 databases, websites, textbooks, conference abstracts and references (1970-February 2010). Studies had two independent reviews (three if disputed) and critical appraisal. PATIENTS: Primary comparative studies of children <11 years old hospitalised with AHT and nAHT diagnosed on CT or MRI. MAIN OUTCOME MEASURES: Neuroradiological features that differentiated AHT from nAHT. RESULTS: 21 studies of children predominantly <3 years old were analysed. Subdural haemorrhages (SDH) were significantly associated with AHT (OR 8.2, 95% CI 6.1 to 11). Subarachnoid haemorrhages were seen equally in AHT and nAHT and extradural haemorrhages (EDH) were significantly associated with nAHT (OR for AHT 0.1, 95% CI 0.07 to 0.18). Multiple (OR 6, 95% CI 2.5 to 14.4), interhemispheric (OR 7.9, 95% CI 4.7 to 13), convexity (OR 4.9, 95% CI 1.3 to 19.4) and posterior fossa haemorrhages (OR 2.5, 95% CI 1 to 6) were associated with AHT. Hypoxic-ischaemic injury (HII) (OR 3.7, 95% CI 1.4 to 10) and cerebral oedema (OR 2.2, 95% CI 1.0 to 4.5) were significantly associated with AHT, while focal parenchymal injury was not a discriminatory feature. SDH of low attenuation were more common in AHT than in nAHT. CONCLUSION: Multiple SDH over the convexity, interhemispheric haemorrhages, posterior fossa SDH, HII and cerebral oedema are significantly associated with AHT and should be considered together with clinical features when identifying the condition.

Sex-related differences in NMDA-evoked rat masseter muscle afferent discharge result from estrogen-mediated modulation of peripheral NMDA receptor activity.

In the present study, the hypothesis that sex-related differences in glutamate-evoked rat masseter muscle afferent discharge may result from estrogen-related modulation of peripheral N-methyl-d-aspartate (NMDA) receptor activity and/or expression was tested by examining afferent fiber discharge in response to masseter injection of NMDA and the expression of NR2A/B subunits by masseter ganglion neurons in male and female rats. The results showed that injection of NMDA into the masseter muscle evoked discharges in putative mechanonociceptive afferent fibers and increased blood pressure that was concentration-dependent, however, a systemic action of NMDA appeared responsible for increased blood pressure. NMDA-evoked afferent discharge was significantly greater in female than in male rats, was positively correlated with plasma estrogen levels in females and was significantly greater in ovariectomized female rats treated with a high dose (5 mug/day) compared with a low dose (0.5 mug/day) of estrogen. Pre-treatment of high dose estrogen-treated-ovariectomized female rats with the Src tyrosine kinase inhibitor PP2 did not affect NMDA-evoked afferent discharge. NMDA-evoked afferent discharge was attenuated by the antagonists ketamine and ifenprodil, which is selective for NR2B containing NMDA receptors. Fewer masseter ganglion neurons expressed the NR2A (16%) subunit as compared with the NR2B subunit (38%), which was expressed at higher frequencies in intact female (46%) and high dose estrogen-treated ovariectomized female (60%) rats than in male (31%) rats. Taken together, these results suggest that sex-related differences in NMDA-evoked masseter afferent discharge are due, at least in part, to an estrogen-mediated increase in expression of peripheral NMDA receptors by masseter ganglion neurons in female rats.

Sensitivity of rat temporalis muscle afferent fibers to peripheral N-methyl-D-aspartate receptor activation.

The temporalis muscle is a common source of pain in headache and chronic craniofacial pain conditions such as temporomandibular disorders, which have an increased prevalence in women. The characteristics of slowly conducting temporalis afferent fibers have not been investigated. Therefore, the aim of the present study was to examine the characteristics of slowly conducting temporalis muscle afferent fibers and to determine whether these fibers are excited by activation of peripheral N-methyl-D-aspartate receptors. The response properties of a total of 117 temporalis afferent fibers were assessed in male and female rats. A majority of these fibers had high mechanical thresholds and slow conduction velocities (<10 m/s). The mechanical threshold of the temporalis afferent fibers was inversely correlated with afferent conduction velocity, however, no sex-related differences in mechanical threshold were identified. There were also no sex-related differences in N-methyl-D-aspartate-evoked afferent discharge. Indeed, injection of a high concentration (1600 mM) of N-methyl-D-aspartate into the temporalis muscle was necessary to evoke significant afferent discharge. Thirty minutes after the initial injection of N-methyl-D-aspartate into the temporalis muscle, a second injection of N-methyl-D-aspartate produced a response only about 50% as large as the initial injection. Co-injection of ketamine (20 mM) with the second injection of N-methyl-D-aspartate significantly decreased N-methyl-D-aspartate-evoked afferent discharge in both sexes. This concentration of ketamine is greater than that needed to attenuate afferent discharge evoked by injection of glutamate into the masseter muscle. These results suggest that unlike masseter afferent fibers, temporalis afferent fibers are relatively insensitive to peripheral N-methyl-D-aspartate receptor activation.

Are there patterns of bruising in childhood which are diagnostic or suggestive of abuse? A systematic review.

AIMS: To investigate what patterns of bruising are diagnostic or suggestive of child abuse by means of a systematic review. METHODS: All language literature search 1951-2004. Included: studies that defined patterns of bruising in non-abused or abused children <18 years. Excluded: personal practice, review articles, single case reports, inadequate confirmation of abuse. Two independent full text reviews using standardised data extraction and critical appraisal forms. Studies ranked by study design and definition of abuse used. RESULTS: Twenty three studies included: seven non-abusive bruising, 14 abusive bruising, and two both. Non-abusive: The prevalence, number, and location of bruises is related to increased motor development. Bruising in non-independently mobile babies is very uncommon (<1%). Seventeen per cent of infants who are starting to mobilise, 53% of walkers, and the majority of schoolchildren have bruises. These are small, sustained over bony prominences, and found on the front of the body. Abuse: Bruising is common in children who are abused. Any part of the body is vulnerable. Bruises are away from bony prominences; the commonest site is head and neck (particularly face) followed by the buttocks, trunk, and arms. Bruises are large, commonly multiple, and occur in clusters. They are often associated with other injury types that may be older. Some bruises carry the imprint of the implement used. CONCLUSION: When abuse is suspected, bruising must be assessed in the context of medical, social, and developmental history, the explanation given, and the patterns of non-abusive bruising. Bruises in non-mobile infants, over soft tissue areas, that carry the imprint of an implement and multiple bruises of uniform shape are suggestive of abuse. Quality research across the whole spectrum of children is urgently needed.

Can you age bruises accurately in children? A systematic review.

AIMS: To investigate whether it is possible to determine the age of a bruise in a child in clinical practice by means of a systematic review. METHODS: An all language literature search up to 2004. Included studies assessed the age of bruises in live children less than 18 years old. Excluded: review articles, expert opinion, and single case reports. Standardised data extraction and critical appraisal forms were used. Two reviewers independently reviewed studies. RESULTS: Of 167 studies reviewed, three were included: two studies described colour assessment in vivo and one from photographs. Although the Bariciak et al study showed a significant association between red/blue/purple colour and recent bruising and yellow/brown and green with older bruising, both this study and Stephenson and Bialas reported that any colour could be present in fresh, intermediate, and old bruises. Results on yellow colouration were conflicting. Stephenson and Bialas showed yellow colour in 10 bruises only after 24 hours, Carpenter after 48 hours, and Bariciak et al noted yellow/green/brown within 48 hours. Stephenson and Bialas reported that red was only seen in those of one week or less. The accuracy with which clinicians correctly aged a bruise to within 24 hours of its occurrence was less than 40%. The accuracy with which they could identify fresh, intermediate, or old bruises was 55-63%. Intra- and inter-observer reliability was poor. CONCLUSION: A bruise cannot accurately be aged from clinical assessment in vivo or on a photograph. At this point in time the practice of estimating the age of a bruise from its colour has no scientific basis and should be avoided in child protection proceedings.

Hepatitis B immune globulin: final report of a controlled, multicenter trial of efficacy in prevention of dialysis-associated hepatitis.

In a randomized, double-blind multicenter trial, 284 patients and 282 staff members of renal dialysis units who lacked detectable hepatitis B surface antigen (HBsAg) and antibody to HBsAg (anti-HBs) were randomly assigned to receive two 3-ml injections of immune serum globulin with high, intermediate, or low titers of anti-HBs four months apart. The incidence of infection with hepatitis B and of development of HBsAg was significantly lower in both patients and staff who received the high-titer material than in subjects who received the low-titer preparation eight but not 12 months after randomization (P less than 0.01 for patients and P less than 0.04 for staff, low-titer vs. high-titer at eight months). The high-titer hepatitis B immune globulin preparation did not appear to affect the severity of the cases of hepatitis that did occur, the proportion of subjects who developed persistent antigenemia, or the magnitude or timing of primary anti-HBs responses.

Hepatitis B "immune" globulin: effectiveness in prevention of dialysis-associated hepatitis.

A randomized, double-blind, multicenter study of hepatitis prevention by immune serum globulin with high anti-HBs titer ("hepatitis B immune globulin") was carried out among 318 new patients and 296 staff members of renal dialysis units. Three milliliters of high titer globulin, repeated at four months, was compared with equal doses of intermediate or normal titer globulin. Among staff members, the cumulative percentages developing hepatitis or HBs Ag, or both, within eight months were 6.9, 11.7, and 11.1 in the high, intermediate, and normal titer groups respectively. The lower incidence associated with high titer globulin was not significant (P greater than 0.05). However, among the patients the respective percentages were 7.9, 21.3, and 23.1 and the lower incidence in the high titer globulin group was significant.
