Respiratory admissions and impact of COVID-19 lockdowns for children with severe cerebral palsy.

Aim: To explore factors contributing to the burden of respiratory admissions in children with severe cerebral palsy (CP) by comparing admissions to a single tertiary paediatric hospital before, during, and after the period of social restrictions implemented to reduce transmission of COVID-19 (lockdown period).

Method: For this observational study, three severe CP cohorts (pre-lockdown, lockdown, post-lockdown) were identified from a state-wide cerebral palsy register and linked to patient-level clinical and demographic data. Medical records were manually searched to identify respiratory hospitalizations.

Major structural congenital anomalies and causal pathways in people with cerebral palsy.

Aim: To determine the proportion of persons with cerebral palsy (CP) with major congenital anomalies, factors associated with the presence of anomalies, body systems involved, potential contribution to CP aetiology, and causal pathway subgroups implicated.

Method: This population-based, observational study involved a cohort of 2238 persons born in one Australian state between 1999 and 2017. Major congenital anomalies were classified as affecting cerebral, cardiac, or other body systems, with further categorization as single or multisystem.

Neonatal well-being and timing of brain injury in persons with cerebral palsy born at term or late preterm.

Aim: To describe the distribution of neuroimaging patterns in a term/late preterm population-based cohort with cerebral palsy (CP), ascertain associations between neuroimaging patterns and neonatal well-being, estimate the proportion with antenatal or perinatal timing of neuropathology, and apply this information to the understanding of common mechanisms of brain injury and causal pathways.

Method: The cohort for this observational study comprised 1348 persons born between 1999 and 2017 in Victoria, Australia. Using algorithms designed for the study, neonatal well-being and timing of brain injury were tabulated for the whole cohort and across neuroimaging patterns and birth epochs.

Developmental outcomes for survivors of placental laser photocoagulation for the management of twin-to-twin transfusion syndrome.

Background: Fetoscopic laser coagulation of placental anastomoses reverses the pathological process in twin-to-twin transfusion syndrome, thereby increasing survival, but there are a paucity of studies addressing long-term neurodevelopmental outcome of survivors. This study aimed to ascertain the presence of neurodevelopmental disabilities in child survivors of monochorionic pregnancies managed by placental laser photocoagulation in the Australian state of Victoria.

Methods: All pregnancies undergoing placental laser photocoagulation with the Victorian Fetal Therapy Service between 2006-2017 were included.

Causation in cerebral palsy: Parental beliefs and associated emotions.

Aim: To better understand parents' beliefs about causation in cerebral palsy (CP) and the emotions related to those beliefs.

Method: We surveyed 226 parents of children with CP aged 1 to 18 years, recruited from the Victorian Cerebral Palsy Register, to evaluate their beliefs about the causes of CP, including genetic causes, causes specific to their own child, and their attitudes and emotions in relation to these.

Results: Although 92% of participants reported that understanding the causes of their child's CP was important, uncertainty about the cause was expressed by 13%.

Survival of individuals with cerebral palsy in Victoria, Australia: A longitudinal cohort study spanning four decades.

Aim: To provide an updated description of the rates, trends, and predictors of mortality of individuals with cerebral palsy (CP), born in the Australian state of Victoria between 1970 and 2012.

Method: Data were extracted for 4807 individuals (2091 females; 2716 males). The probability of survival to 30th June 2017 was calculated using the Kaplan-Meier method.

Growth Trajectories in Genetic Subtypes of Prader-Willi Syndrome.

Prader-Willi syndrome (PWS) is a rare disorder caused by the loss of expression of genes on the paternal copy of chromosome 15q11-13. The main molecular subtypes of PWS are the deletion of 15q11-13 and non-deletion, and differences in neurobehavioral phenotype are recognized between the subtypes. This study aimed to investigate growth trajectories in PWS and associations between PWS subtype (deletion vs.

Anticholinergic medications for reducing drooling in children with developmental disability.

Aim: To determine: the effectiveness of three anticholinergic medications in reducing drooling in children with developmental disabilities (such as cerebral palsy, intellectual disability, and autism spectrum disorder), the frequency and nature of side effects, and their impact on treatment discontinuation.

Method: After prescription of benzhexol hydrochloride, glycopyrrolate, or scopolamine patches at a tertiary saliva control clinic, all carers of 110 consecutive, eligible patients were recruited over a 5-year period. They provided data for 52 weeks, or until drug discontinuation, on compliance, drooling, adverse effects, and reasons for cessation.

Long-term impact of saliva control surgery in children with disability.

Sialorrhea is a common problem in children with disability, often negatively affecting socialization, self-esteem, and burden of care. Saliva control surgery is an available option to manage this problem, particularly when other conservative methods have failed. As little is known about the long-term impact of surgery, we followed up 62 patients who had combined bilateral submandibular duct translocation and bilateral sublingual gland excision at our pediatric hospital between 1994 and 2014.

Twin-to-twin transfusion syndrome neurodevelopmental follow-up study (neurodevelopmental outcomes for children whose twin-to-twin transfusion syndrome was treated with placental laser photocoagulation).

Background: Twin-to-twin transfusion syndrome (TTTS) is a serious complication of 10-15% of twin or triplet pregnancies in which multiple fetuses share a single placenta. Communicating placental vessels allow one fetus (the donor) to pump blood to the other (the recipient). Mortality rates without intervention are high, approaching 100% in some series, with fetal deaths usually due to cardiac failure.
