RESUMEN
PURPOSE: Botulinum toxin-A (or Botox) is widely used for the management of equinus gait in children with cerebral palsy but few recent studies have included instrumented gait analysis. METHODS: This was a prospective cohort study. Gait analysis was performed four weeks before and four weeks after Botulinum toxin-A injection for spastic equinus to detect the maximum effects on gait kinematics. Outcome measures included the Gait Profile Score (GPS), the Gait Variable Score (GVS) for the ankle, maximal ankle dorsiflexion and maximal knee extension at midstance. RESULTS: In all, 37 children participated (20 boys); mean age five years seven months (4 years 1 month to 8 years 2 months); 19 with unilateral and 18 bilateral involvement. At a mean four weeks post-injection, the GPS and ankle GVS were unchanged. However maximum ankle dorsiflexion increased for the whole group; median 7.7° (confidence interval (CI) 4° to 10.6°) to 11.5° (CI 7.7° to 12.9°), p = 0.02. Maximum midstance knee extension was unchanged for the whole group, but median knee flexion increased in children with bilateral involvement; 10.9° (CI 7.4° to 20.8°) to 16.5° (CI 8.4° to 19.7°), p = 0.58. CONCLUSION: Injections of the gastrocsoleus for spastic equinus did not result in objective improvements in overall gait. Improvements in ankle dorsiflexion for children with bilateral involvement may be offset by deterioration at the knee. LEVEL OF EVIDENCE: II - prospective cohort study, before and after intervention.
RESUMEN
BACKGROUND: Many previous studies that have investigated hospital admissions in children and young people with cerebral palsy lack information on cerebral palsy severity and complexity. Consequently, little is known about factors associated with the frequency and type of hospital admissions in this population. This study used hospital admission data available for all children and young people known to a population-based cerebral palsy register to describe the patterns of use of tertiary paediatric hospital services over a 5-year period. METHODS: This was a retrospective cohort analysis of routinely collected admission data from the two tertiary paediatric hospitals in the Australian state of Victoria. Data on admissions of individuals born between 1993 and 2008 registered on the Victorian Cerebral Palsy Register were analysed (n = 2183). RESULTS: Between 2008 and 2012, 53% of the cohort (n = 1160) had at least one same-day admission, and 46% (n = 996) had one or more multi-day admissions. Those with a moderate to severe motor impairment and those with a co-diagnosis of epilepsy had more admissions, and for multi-day admissions, longer lengths of stay, P < 0.05. Across all severity levels, respiratory and musculoskeletal diseases were the most frequently reported reasons for medical and surgical admissions, respectively. All-cause readmission rates for urgent multi-day stays within 7, 30 and 365 days of an index admission were 10%, 23% and 63%, respectively. CONCLUSIONS: The reasons for hospital admissions reported here reflect the range of comorbidities experienced by children and young people with cerebral palsy. This study highlights priority areas for prevention, early diagnosis and medical management in this group. Improved primary and secondary prevention measures may decrease non-elective hospital admissions and readmissions in this group and reduce paediatric inpatient resource use and healthcare expenditure attributable to cerebral palsy.

Upper limb spasticity affecting elbow, wrist, and finger flexors can be safely and effectively reduced with injections of botulinum toxin type-A (BoNT-A). It has been best studied in adults in the context of post-stroke spasticity. The clinical benefits include reduction in pain and deformity, improvement in washing and dressing the upper limb, and a reduction in caregiver burden (Class I evidence, recommendation level A). Some patients show improvement in function performed by active movement of the affected upper limb (Class III evidence, recommendation C), but predicting and measuring this is difficult, and further research is needed. An individually based approach to treatment and outcome measurement is preferred (Class IV, recommendation U). More research is needed to resolve many unknown issues of assessment and treatment, using research methods appropriate to the question.

Evidence is emerging for the use of botulinum neurotoxin type-A (BoNT-A) for niche indications including pain independent of spasticity. Pain indications such as chronic nociceptive back pain, piriformis syndrome, chronic myofascial pain, pelvic pain, complex regional pain syndrome, facial pain and neuropathic pain are outlined in this paper. Of these, class I evidence is available for the treatment of chronic nociceptive low back pain, piriformis syndrome, myofascial pain, facial pain, neuropathic pain and plantar fasciitis. Peri-operative use of BoNT-A is emerging, with indications including planning for surgery and facilitating surgery, as well as healing and improving analgesia post-operatively. Evidence is limited, although there are some reports that clinicians are successfully using BoNT-A peri-operatively. There is class I evidence showing pre-operative use of BoNT-A has a beneficial effect on outcomes following adductor-release surgery. The use of BoNT for treatment of tremor, other than neck tremor in the setting of cervical dystonia, including evidence for upper limb tremor, cranial tremor and non-dystonic neck tremor is reviewed. The evidence is variable at this stage, and further study is required to develop definitive recommendations for the clinical utility of BoNT-A for these indications.

The primary aim of this randomized, controlled trial was to assess the effectiveness of botulinum toxin A (BoNT-A) injections into the submandibular and parotid glands on drooling in children with cerebral palsy (CP) and other neurological disorders. Secondary aims were to ascertain the duration of any such effect and the timing of maximal response. Of the 48 participants (27 males, 21 females; mean age 11y 4mo [SD 3y 3mo], range 6-18y), 31 had a diagnosis of CP and 15 had a primary intellectual disability; 27 children were non-ambulant. Twenty-four children randomized to the treatment group received 25 units of BoNT-A into each parotid and submandibular gland. Those randomized to the control group received no treatment. The degree and impact of drooling was assessed by carers using the Drooling Impact Scale questionnaire at baseline and at monthly intervals up to 6 months postinjection/baseline, and again at 1 year. Maximal response was at 1 month at which time there was a highly significant difference in the mean scores between the groups. This difference remained statistically significant at 6 months. Four children failed to respond to the injections, four had mediocre results, and 16 had good results. While the use of BoNT-A can help to manage drooling in many children with neurological disorders, further research is needed to fully understand the range of responses.

OBJECT: The goal of this study was to assess the long-term benefits of managing severe spasticity by using continuous infusion of intrathecal baclofen delivered via an implantable pump. METHODS: Eighteen patients with severe spasticity of cerebral origin, who failed to respond adequately to more conservative treatments, have-been treated with continuous infusion of intrathecal baclofen delivered via an implanted pump. Follow-up review of these patients has lasted between 12 months and 9 years. The patients have been assessed using a variety of tools. Seventeen have had a significant reduction in tone and all have benefited by a reduced need for nursing care or increased function or both. CONCLUSION: Long-term continuous infusion of intrathecal baclofen delivered via an implantable pump offers an effective method for dealing with otherwise intractable spasticity.

A 34-year-old quadriplegic man with a C6/C7 spinal cord lesion of 10 years' duration fathered a child with his 35-year-old wife who had undergone a premature menopause 10 years earlier. Pregnancy was achieved from in-vitro fertilization of two oocytes donated by the wife's sister using spermatozoa from the husband obtained by repeated electro-ejaculation techniques. A healthy male infant weighing 2250 g was delivered by Caesarean section at 37 weeks following mild pre-eclampsia.
