Correlation between retinal abnormalities and intracranial abnormalities in the shaken baby syndrome.

PURPOSE To report correlation between retinal and intracranial abnormalities and to evaluate pathogenesis of retinal hemorrhages in the shaken baby syndrome (SBS). DESIGN Observational case series. METHODS Seventy-five children with apparent nonaccidental head trauma consistent with SBS had complete physical examination, complete ophthalmologic examination, neuroimaging by CT or MRI, or both, and skeletal radiographic survey. In this retrospective review, ophthalmoscopic and intracranial abnormalities were correlated. RESULTS The age of patients ranged from 2 to 48 months (mean - SD, 10.6 +/- 10.4 months). Neuroimaging was abnormal in all 75 cases. Findings included subdural hematoma (70 children, 93%), cerebral edema (33 children, 44%), subarachnoid hemorrhage (12 children, 16%), vascular infarction (nine children, 12%), intraparenchymal blood (six children, 8%), parenchymal contusion (six children, 8%), and epidural hemorrhage (one child, 1%). Sixty-four (64/75, 85%) children had retinal abnormalities, mostly (53/64, 82%) confluent multiple hemorrhages that were subretinal, intraretinal, and preretinal in 47/64 (74%) and bilateral in 52/64 (81%). No association was found between anatomic site (left, right, or bilateral) of intracranial and retinal findings (McNemar test kappa = -0.026-0.106) or between any of the intracranial findings mentioned above and the following retinal findings: normal or abnormal retinal examination, multiple (>10) or few retinal hemorrhages (< or =10), symmetric or asymmetric retinal findings, or retinoschisis (kappa = -0.127-0.104). Signs of possible increased intracranial pressure were not correlated with any retinal abnormality (kappa = -0.03-0.073). There was no correlation between evidence of impact trauma to the head and retinal hemorrhages (kappa = 0.058). Total Cranial Trauma Score and Total Retinal Hemorrhage Score, both indicating the severity of injury, were correlated (P =.032). CONCLUSIONS Our study supports previous observations that the severity of retinal and intracranial injury is correlated in SBS. We cannot support the suggestions that in most children with SBS retinal bleeding is caused by sustained elevated intracranial, elevated intrathoracic pressure, direct tracking of blood from the intracranial space, or direct impact trauma. The correlation in severity of both eye and head findings may suggest, however, that retinal abnormalities are the result of mechanical shaking forces.

Review of 125 children 6 years of age and under who were sexually abused.

The authors present a chart review of 125 children, 6 years of age and under, who presented between early 1981 and mid 1983 to an acute care hospital because of sexual abuse. They represented one-third of the cases of alleged sexual abuse between infancy and 18 years of age referred to the hospitals multidisciplinary sexual abuse team. The ratio of females to males was 3.3:1. Sixty percent of the children were victims of intrafamilial abuse. Of the preschoolers, 72.5% were victims of intrafamilial abuse. At school age there was a reversal with 73% of 6 year olds being abused by extrafamilial offenders. The duration of the abusive relationship was greater in intrafamilial abuse. Purposeful disclosures were more frequent overall but were significantly less frequent when the perpetrator was intrafamilial or when the child was a preschooler. Two-thirds of the children had physical and/or behavioral symptoms. Parents of children who had been the victims of intrafamilial abuse were more likely to be separated or divorced. The difficulties in assessing young victims of alleged sexual abuse and the implications of the findings in this review are discussed.

Retinal findings after head trauma in infants and young children.

BACKGROUND Many authorities believe that the finding of retinal hemorrhages in a child younger than 3 years of age with a history of head trauma, in the absence of an obvious cause for the injury, is pathognomonic of child abuse. To date, no studies have examined the prospective retinal examination of children who have had head trauma. The authors undertook such a study because the presence of retinal hemorrhage from any head trauma in children may have medicolegal diagnostic significance in differentiating accidental from nonaccidental trauma. METHODS Seventy-nine children younger than 3 years of age, each of whom experienced head injury, underwent an ophthalmologic assessment, which included a dilated funduscopic examination. RESULTS Seventy-five children sustained accidental head injuries and had normal funduscopic examinations. Three children had nonaccidental head injuries and all were found to have varying degrees of retinal hemorrhages. One child, with a normal fundus examination, had injuries that were of indeterminate cause. CONCLUSION The finding of retinal hemorrhages in a child with a head injury suggests a nonaccidental cause.

The effects of sexual abuse on 3- to 5-year-old girls

This study examined the initial effects of sexual abuse on 70 girls aged 3 to 5 years. They were compared to a control group of 42 nonabused nonclinical girls matched for age. Of the 70 girls in the abused group, the 42 who had experienced intrafamilial abuse were also compared to the 28 who had experienced extrafamilial abuse. Evaluation of effects was based on maternal reports and very importantly, given this young age group, on direct observation. Children from both abuse groups displayed more evidence of distress on all measures. In particular, more sexual behaviors and more internalizing problem behaviors were reported and observed. Girls who were abused by a member of their family demonstrated some elevations in symptomatology, but generally there was not a significant difference between the two abuse groups. Poorer outcome was associated with a more noxious family environment and with repeated, more invasive abuse. The association of abuse and family characteristics that exacerbated the effects of sexual abuse on the child underscores the need for early detection and careful clinical assessment of the family as well as the child.

Guidelines for Postmortem Protocol for Ocular Investigation of Sudden Unexplained Infant Death and Suspected Physical Child Abuse

Postmortem examination is a cornerstone in identifying the cause of unexplained sudden death in children. Even in cases of suspected or known abuse, an autopsy may help characterize the nature of the abuse, which is particularly important in the forensic autopsy of children in the first 3 to 4 years of life when inflicted neurotrauma is most common. Forensic examinations are vital in cases that might otherwise be diagnosed as sudden infant death syndrome. The ocular autopsy in particular may demonstrate findings that were not appreciated on antemortem clinical examination. This protocol for postmortem examination of the eyes and orbits was developed to promote more consistent documentation of findings, improved clinical and forensic decision making, and more replicable and coherent research outcomes.

Look Who’s Talking: Teaching and Learning Using the Genre of Medical Case Presentations

In a pediatric teaching hospital, the authors examined 16 novice medical case presentations that were classified as instances of a hybrid apprenticeship genre. In contrast to strict school and workplace genres, an apprenticeship genre results from the sometimes competing activity systems of student education and patient care. The authors examined these novice case presentations for the amount and patterns of time devoted to student learning and expert teaching, the difficulties created for participants, the sometimes misunderstood implicit messages delivered by experts, and the opportunities to address educational objectives. This study offers professional communication researchers a model that combines quantitative and qualitative methodologies to assess the effects of competing activity systems in the development of communication expertise.

Impact of lifestyle and dietary habits on hypovitaminosis D in type 1 diabetes mellitus and healthy children from Qatar, a sun-rich country.

BACKGROUND There are no population-based studies that have examined the association between vitamin D and type 1 diabetes mellitus (T1DM) and the role of lifestyle habits and dietary factors in young children in the Arabian Gulf and Middle East region. Little data on the intake of these nutrients in Mediterranean countries exist, and predictors of their suboptimal intake are not well defined. OBJECTIVE The objective of this study was to determine the association between vitamin D status and T1DM and assess the impact of lifestyle and dietary habits on hypovitaminosis D in the young population of the State of Qatar. A matched case-control study was carried out among T1DM children and healthy subjects <16 years of age at the pediatric endocrinology outpatient clinics of the Hamad General Hospital and the primary health care clinics center. The survey was conducted over a period from 6 August to 25 December 2007. The sample included 170 cases and 170 controls matched by age, gender and ethnicity. METHODS Face to face interviews were based on a questionnaire that included variables such as sociodemographic information, assessment of non-dietary covariates, assessment of dietary intake including vitamin D, type of feeding, clinical manifestations and laboratory investigations. Their health status was assessed by medical conditions, family history, body mass index, past or present clinical manifestations, serum 25(OH) vitamin D, calcium, alkaline phosphates, phosphorus, hemoglobin A1C, parathyroid hormone, magnesium and creatinine analysis. RESULTS The study revealed that the incidence of severe vitamin D deficiency was considerably higher in T1DM (28.8%) compared with healthy children (17.1%). Although the mean serum level of vitamin D was significantly lower in T1DM children (15.80+/-9.23 ng/ml), compared with nondiabetic children (18.45+/-9.56 ng/ml), both groups belonged to the mild-moderate vitamin D deficiency category. A family history of vitamin D deficiency (35.3%; p=0.012) and diabetes mellitus (56.5%; p<0.001) was significantly higher in diabetic children. More than half of the diabetic (67.1%) and healthy children (51.2%) had no physical activity in their daily life. Both groups (65.9 vs. 62.9%) had very limited exposure to sunlight. Vitamin D supplement intake was very poor in diabetic children compared with healthy children; 60% of diabetic and 40.6% of healthy children never had any vitamin D supplement. The study revealed that vitamin D serum concentration, phosphorus, hemoglobin A1C, magnesium and creatinine show statistically significant differences between T1DM and healthy control subjects. A significant difference was noted between diabetic and healthy children for fractures (p=0.005), weakness (p=0.001) and gastroenteritis (p=0.025). CONCLUSIONS The present study revealed that vitamin D deficiency is a common problem in Qatari children, but the incidence of vitamin D deficiency becomes very severe in T1DM children, compared with healthy children. This suggests that there is an association between vitamin D deficiency and T1DM. The data show that vitamin D status is dependent on sunshine exposure and dietary vitamin D intake. The results suggest the necessity of nutrition education to promote healthy eating habits among adolescents and their parents.

The Trial of the Expert Witness: Negotiating Credibility in Child Abuse Correspondence.

This article reports on forensic letters written by physicians specializing in identifying children who have experienced maltreatment. These writers face an extraordinary exigence in that they must provide an opinion as to whether a child has experienced abuse without specifically diagnosing abuse and thus crossing into a legal domain. Their credibility was also at issue because, in this jurisdiction, child abuse identification was not recognized as a medical subspecialty and because the status of expert witnesses is currently being challenged. Through an analysis of 72 forensic letters combined with interview data from six letter writers and five letter readers, we determined that these writers used linguistic and rhetorical strategies that allowed these letters to function as boundary objects or objects that traverse several communities of practice. The most salient strategy was the use of evaluative lexis—adjectives and adverbs which allowed for a range of interpretations and constrained those interpretations at the same time.

Familial Risk Factors Associated with Intrafamilial and Extrafamilial Sexual abuse of three to Five Year Old Girls

This study intended to identify familial risk factors which differentiate sexually abused young girls from nonabused girls and, further, young victims of intrafamilial from those of extrafamilial sexual abuse. The subjects were 112 girls aged three to five years and their families. Forty-two were the victims of intrafamilial sexual abuse and 28 were victims of extrafamilial sexual abuse while 42 girls were not the victims of abuse. The three groups of girls were matched for age. Comparisons indicated that the families of abused girls had less harmony and stability in the marital unit and were headed by less competent parents. Mothers in both abuse groups were significantly more likely to have experienced sexual abuse as children. For all comparisons, the intrafamilial group showed greater disadvantage and dysfunction than the extrafamilial group. The intrafamilial group was differentiated from the extrafamilial group by worse spousal relationships, inadequate boundaries in parent-child behaviour, fathers history of physical abuse as a child and violent behaviour as an adult and maternal disapproval of the child victim. These findings suggest that child sexual abuse is related to a longstanding collection of interconnected adult personal and relational deficiencies which result in inadequate parenting for the young victim.

Accessibility and Order: Crossing Borders in Child Abuse Forensic Reports

Physicians write child abuse forensic reports for nonphysicians. We examined 73 forensic reports from a Canadian childrens hospital for recurrent strategies geared toward making medical information accessible to nonmedical users; we also interviewed four report writers and five readers. These reports featured unique forensic inserts in addition to headings, lists, and parentheses, which are typical of physician letters for patients. We discuss implications of these strategies that must bridge the communities of medical, social, and legal practice.
