Further recommendations of the International Paediatric Brain Injury Society (IPBIS) for the post-acute rehabilitation of children with acquired brain injury.

BACKGROUND: Paediatric acquired brain injury is a life-long condition which impacts on all facets of the individual's lived experience. The existing evidence base continues to expand and new fields of enquiry are established as clinicians and researchers uncover the extent of these impacts. PRIMARY OBJECTIVE: To add to recommendations described in the International Paediatric Brain Injury Society's 2016 paper on post-acute care for children with acquired brain injury and highlight new areas of enquiry. REVIEW OF INFORMATION: Recommendations were made based on the opinions of a group of experienced international clinicians and researchers who are current or past members of the board of directors of the International Paediatric Brain Injury Society. The importance of each recommendation was agreed upon by means of group consensus. OUTCOMES: This update gives new consideration to areas of study including injuries which occur in pre-school children, young people in the military, medical referral, young offenders and the use of technology in rehabilitation.

Suppressing visual hallucinations in an adolescent by occipital transcranial magnetic stimulation: A single-case experimental research design.

Visual hallucinations after central or peripheral impairment, commonly called Charles Bonnet syndrome, are often highly distressing and with few available treatment options. Here we report a case where an adolescent developed severely distressing visual hallucinations after hypoxic damage to the occipital cortex following a suicide attempt. The patient received active and sham occipital continuous theta-burst stimulation (cTBS) in a single-case experimental research design and a subsequent open phase, to evaluate cTBS as a Charles Bonnet treatment. The visual hallucinations seemed to decrease more during active than sham cTBS in the blind phase, and in the following week of repeated five daily treatments they almost disappeared. A normalization of increased activity in the lateral visual network after cTBS was observed on a functional magnetic resonance imaging resting-state analysis compared with 42 healthy controls. Visual evoked potentials stayed largely unchanged both in the sham-controlled blind phase and the subsequent open phase. During the two weeks after the open phase with repeated cTBS sessions, the visual hallucinations gradually reappeared and almost returned to the baseline level. Our findings suggest that active cTBS over the primary visual cortex can reduce visual hallucinations through modulation of downstream visual regions, though the effect is temporally limited.

Clinical characteristics, long-term complications and health-related quality of life (HRQoL) in children and young adults treated for low-grade astrocytoma in the posterior fossa in childhood.

INTRODUCTION: Pilocytic astrocytoma is the most common brain tumour in childhood but knowledge concerning its long-term outcome is sparse. The aim of the study was to investigate if children treated for low-grade pilocytic astrocytoma in the posterior fossa had complications affecting physical and psychological health, cognitive functions, learning difficulties and HRQoL. METHODS: A descriptive single-centre study, where 22 children and young adults out of 27 eligible patients (81%) treated for pilocytic astrocytoma, with a mean follow-up time of 12.4 years (5-19 years) participated (14 adults, two by telephone interviews and eight children). The study included a review of medical records, an interview, neurological investigation, screening tools for psychiatric symptoms (Beck Depression and Anxiety Inventories and Beck Youth Inventory Scales) and HRQoL measures (RAND-36). RESULTS: Motor complications were most common, reported in 12 patients and mainly affecting fine-motor skills. Seven patients reported cognitive difficulties affecting performance in school. Educational support was given in the period immediately after treatment but not after primary school. None had elevated levels of psychiatric symptoms and the level of HRQoL as well as their psychosocial and educational situation was in correspondence with Swedish norms. The HRQoL score for vitality (VT) almost reached statistical significance. CONCLUSIONS: The long-term functional outcome for children treated for low-grade astrocytoma is favourable. However, some patients report neurological complications and learning difficulties, which are unmet in school. Therefore, there is a need to identify those who need more thorough medical and cognitive follow-up programmes including interventions in school.

Service provision for children and young people with acquired brain injury: Practice recommendations.

BACKGROUND: Providing appropriate rehabilitation services for Acquired Brain Injury (ABI) in childhood presents a number of challenges for caregivers, health and education professionals and the young person as they develop. PRIMARY OBJECTIVE: To record the challenges and possible creative solutions generated by an international group of professionals to address the needs of children with ABI. Review of information: Recommendations were generated from children's special interest group meetings of the International Brain Injury Association (Turin, Italy, 2001; Stockholm, Sweden, 2003; Melbourne, Australia, 2005; Lisbon, Portugal, 2008) and through meetings of the International Paediatric Brain Injury Society (IPBIS), formed in 2009. Delegates participating in the workshops were representative of nations from around the world and included The Netherlands, New Zealand, Australia, the UK, Finland, Germany, South Africa, the US, Canada, Sweden, Brazil and Italy. OUTCOMES: The information presented is based on a retrospective review of those meetings and the summaries of the topics considered.

Motor performance after treatment of pilocytic astrocytoma in the posterior fossa in childhood.

BACKGROUND: Pilocytic astrocytoma is the most common brain tumour type in childhood located in the posterior fossa, and treated mainly with surgery. These tumours have low mortality, but knowledge concerning its long-term outcome is sparse. AIMS: The aim was to investigate if patients treated for pilocytic astrocytoma in the posterior fossa had motor complications, including balance, motor and process skills. METHODS AND RESULTS: This descriptive single-centre study includes eight children and 12 adults, treated for pilocytic astrocytoma as children. Motor performance was investigated with Bruininks-Oseretsky Test of Motor Proficiency, Second Edition, and dynamic balance with the mini-balance evaluation systems test. Physiological cost index, six-minute walk test, hand grip strength and assessment of motor and process skills were also evaluated. Ten patients reported motor difficulties, mainly from the upper limbs. The motor performance test showed results within normal limits except for manual dexterity, which was significantly below mean (p = .008). In the dynamic balance test patients had significantly lower results compared with controls (p = .036). Physiological cost index, six-minute walk tests and hand grip strength showed results within normal limits. In the Assessment of Motor and Process Skills, patients over 16 years had significantly lower results compared with test norms for motor activities of daily living (ADL) and 30% of all patients scored below the cut-off level for difficulties with motor skills. CONCLUSIONS: Motor performance for patients treated for pilocytic astrocytoma in the posterior fossa in childhood is satisfactory but some patients display difficulties with balance, manual dexterity and ADL motor skills. Thus, it is important to identify those in need of motor follow-up and training.

Cognitive, language, and school performance in children and young adults treated for low-grade astrocytoma in the posterior fossa in childhood.

BACKGROUND: Pilocytic astrocytoma is the most common brain tumour type in childhood located in the posterior fossa, and treated mainly with surgery. These tumours have low mortality, but knowledge concerning its long-term outcome is sparse. AIM: The aim of this study was to investigate whether children treated for pilocytic astrocytoma in the posterior fossa had late complications affecting cognition, language and learning. METHODS: This descriptive single-centre study includes eight children and 12 adults treated as children for pilocytic astrocytoma in the posterior fossa, with a mean follow-up time of 12.4 (range 5-19) years. Well-established tests of intelligence, executive, language and academic function were used. RESULTS: Intelligence tests showed average results compared with norms. Five patients scored <-1 SD (70-84) and 3 low average (85-92) on full scale IQ. The patients scored average on subtests regarding executive function, except for significantly lower results in inhibition/switching (p = .004). In Rey complex figure test half of the patients scored below -1 SD. Language tests were normal except for significantly lower results in naming ability (p = .049) and in inference (p = .046). In academic tests, results were average, except for significantly lower results in reading speed (p = .024). Patients with learning difficulties performed worse in the tests. CONCLUSIONS: The patients' functional outcome was favourable but, a not-negligible part of the patients displayed neurocognitive difficulties as revealed by extensive neuro-cognitive and academic testing. Thus, it is important to identify those in need of more thorough cognitive and pedagogic follow-up programmes, including school interventions.

Early onset autosomal dominant spinocerebellar ataxia with miosis: four cases.

Previously, at least 29 different forms of autosomal dominant spinocerebellar ataxias (SCAs) have been described. We describe a family with four members through three generations with autosomal dominant ataxia in combination with miosis and hyperreflexia. This family's ataxia does not match any of the previously described SCAs and is probably a novel form of SCA. To continue with the search for the genetic background of this disease, more cases are needed.

Clinical characteristics and late effects in CNS tumours of childhood: Do not forget long term follow-up of the low grade tumours.

AIM: To investigate clinical characteristics and late effects of CNS tumours in childhood with a special focus on low-grade tumours, especially low-grade astrocytoma and glioneuronal tumours. METHODS: A retrospective population based study was performed at Uppsala University Children's Hospital, a tertiary referral centre for children with CNS tumours. Patients were identified from the National Brain Tumour Registry and the National Epilepsy Surgery Registry. Hospital medical records were analysed for patients with a follow up of ≥5 years after diagnosis. A re-evaluation of the neuro-pathological diagnosis was performed. RESULTS: A total of 193 patients (age 0-17.99 years) during a twelve-year period (1995-2006) were included; 149 survived ≥5 years. Three larger subgroups could be identified: astrocytic, embryonal and glioneuronal tumours. A supratentorial location was found in 52%. Medical late effects were mainly neurological and endocrinological, affecting 81% and 26% of surviving patients. Cognitive late effects were a frequent finding in the whole group but also in low-grade astrocytoma and glioneuronal tumours (53% and 67%). Thirty per cent had some kind of pedagogic support in school. CONCLUSION: Late effects are common in long-term survivors of CNS tumours in childhood. Low-grade astrocytoma and glioneuronal tumours are no exception, and the findings support the need for long-term follow up.
