Aim: To explore the relationship between raised intracranial pressure (RICP) and retinal haemorrhages in traumatic and non-traumatic childhood encephalopathies., Method: A prospective study of 112 children (35 females and 77 males, age range 0.01mo-17y 8.3mo; mean 5y 8.6mo, median 4y 5.6mo) included 57 accidental traumatic brain injuries (ATBIs), 21 inflicted traumatic brain injuries (ITBIs), and 34 non-traumatic encephalopathy cases. Measurements included intracranial pressure (ICP), cerebral perfusion pressure, pressure-time index of ICP, and number, zone, and layer of retinal haemorrhages on retinal imaging., Results: Group I had measured elevated ICP (n=42), Group II had clinical and/or radiological signs of RICP (n=21), and Group III had normal ICP (n=49). In the combined Groups I and II, 38% had retinal haemorrhages. Multiple logistic regression confirmed that the presence of retinal haemorrhages was significantly related to the presence of RICP independent of age and aetiology; however, the occurrence and overall numbers were not significantly related to the specific ICP level. The numbers of intraretinal (nerve-fibre layer and dot blot) retinal haemorrhages were significantly greater in those with RICP. The ITBI population was significantly different from the other combined aetiological categories., Interpretation: The study results indicate a complex RICP/retinal haemorrhage relationship. There was no evidence of existing retinal haemorrhages being exacerbated or new retinal haemorrhages developing during periods of confirmed RICP., (© 2017 Mac Keith Press.)

The literature regarding the outcome of non-accidental head injury (NAHI) is scarce and lacks specific detail even though it is generally considered to be poor. The purpose of this study is to review the literature to date and report the neurological outcome of these children in detail. Twenty-five children were enrolled and 68% of children were neurologically abnormal at an average follow-up of 59 months. A wide range of abnormalities and outcomes was seen. Speech and language difficulties were present in 64% including autistic spectrum disorder. Cranial nerve abnormalities were present in 20%. Visual deficits and epilepsy compounded learning difficulties in 25% of survivors. Consent for follow-up was more likely to be obtained where the perpetrator was known. The spectrum and degree of severity of neurological abnormalities in survivors of NAHI is extremely variable, with the majority of these children being moderate or severely abnormal. These children require the support of a multi-disciplinary team in the community. Further study regarding the process of follow-up, where complex medicolegal issues exist, are needed in order to facilitate maximum neurological development. [ABSTRACT FROM AUTHOR]
