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. Results: Clinical and demographic profiles, neonatal well‐being, and timing of brain injury differed across neuroimaging patterns. An estimated 57% of the cohort had a complicated neonatal period. Timing of brain injury was antenatal in 57% and perinatal in 41%. A decrease in the relative proportions of perinatal timing of brain injury was observed over a period when the rates of CP in live births at term decreased. Interpretation: This study begins to bridge the knowledge gap about causation in CP, moving towards better description of the main mechanisms of brain injury and their contribution within CP cohorts, and facilitating the ability to monitor changes over time and the success of preventive measures. What this paper adds: In a population‐based, term/late preterm cohort with cerebral palsy, 57% had a complicated neonatal period.In the same cohort, 57% had presumed antenatal timing of brain injury.The relative proportion with perinatal injury decreased over time.

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%. The most frequently endorsed causal factors, in general and in their own child respectively, were intrapartum hypoxia (81%, 36%) or brain damage (69%, 22%), brain damage during pregnancy (73%, 28%), and preterm birth (66%, 28%). Genetic causes were deemed relevant by 13% of participants and hospital or professional error by 16%. Parents shared related feelings of anger (59%), sadness (80%), guilt (61%), and confusion (53%); parental anger was more likely when their child's CP was attributed to intrapartum events. Interpretation: Substantial parental interest in understanding the causes of CP, together with uncertainty about the causes, parents' causal attributions, and significant emotional sequelae, highlight a strong need for provision of information and support for families of children recently diagnosed with CP. What this paper adds: Understanding the causes of their child's cerebral palsy (CP) was important to parents.Parents most often endorsed intrapartum factors as a cause of CP.Parents reported experiencing strong emotions about the causes of their child's CP.

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. Information on each surviving child, including demographics, perinatal course, and developmental progress was collected from parents, and consent was sought to complete the Child Behaviour Checklist. Interviewers evaluated whether this information was consistent with a diagnosis of any of 14 neurodevelopmental conditions. A three-tiered outcome measure was allocated for each child: (1) unimpaired or developmentally normal, (2) mild or moderate neurological impairment, or (3) severe neurological impairment. Clinical predictors for adverse outcome were identified. Results: Of 116 pregnancies (113 twin, 3 triplet), 96 (83%) resulted in 1 + surviving fetuses. 57/113 (50%) twin pregnancies resulted in 2 survivors, 36 (32%) in 1 survivor, and 20 (18%) in no survivors. Of the 235 fetuses, 154 (65.5%) survived to follow-up. Survival increased from 59% in 2006–2008 to 73% in 2015–2017. 90/154 (58%) survivors were followed up at a mean age of 7.5 [SD 3.0] years. Based on parental interview and Child Behaviour Checklist data, 28/90 (31%) participants were assessed as having neurodevelopmental impairment, 27 of mild-moderate severity and 1 severe. Speech/language disorders, attention deficit (hyperactivity) disorders, and fine motor impairment were most common. Neonatal length of stay conferred the highest risk of impairment. Conclusion: Substantial variation exists between fetal therapy services in the type and length of neonatal follow-up following fetoscopic laser coagulation, contributing to a lack of data on long-term outcomes. The findings from this study support increasingly urgent calls to undertake systematic and sustained follow-up of fetoscopic laser coagulation survivors until school age. Information from this study may assist parents in their decision-making when offered fetal surgery. Importantly, it highlights a group for targeted surveillance and early intervention.

OBJECTIVE: The aims of the current study were to (1) establish baseline data for cervical range of motion (CROM) and joint position sense (JPS) in elite male cricketers, (2) determine whether these players had differences when compared to healthy adults, and (3) establish a reference set of values for future investigations. MATERIALS AND METHODS: Design: Repeated measures, observational study. Participants: Thirty-one elite cricketers, aged 18–35 years. Setting: Cricket New South Wales at the Sydney Cricket Ground, Sydney, Australia. Outcome measures: Cervical rotation was measured with a CROM device and JPS using the joint position error (JPE) laser method with two protocols: repositioning to straight ahead and to 80% of maximum rotation. RESULTS: Mean right and left rotation were less than healthy normals by 6.5° (P < 0.001) and 4.2° (P < 0.001), respectively. In the preseason, 26% of cricketers had JPE >4.5° repositioning to straight ahead, which is 11% greater than the general population and 87% had JPE >4.5° when repositioning to 80% rotation. Postseason, deficits in CROM were unchanged. Fewer players (22%) had JPE >4.5° when repositioning to straight ahead however JPE when repositioning to 80% of rotation increased 1° for both directions (P < 0.05). CONCLUSIONS: Contrary to the authors' hypothesis, preliminary findings from this study demonstrated that elite male cricketers in this cohort had deficits in CROM and JPS, compared to normal healthy adults. This has clinical implications for the use of physical therapies targeting JPS and restoring CROM pre- and post-head and neck injury. Therapists should account for preexisting, baseline asymmetries in the range of motion and JPE in male cricketers. Further research needs to validate these findings across adolescent and female cricketers and explore the interaction between cervical spine parameters, cricket biomechanics, and head or neck injury risk.

CP subgroups To explore whether specific aetiological and clinical variables, or combinations thereof, were related to extreme biomarker values in CP cases, additional variables were extracted from the Victorian Cerebral Palsy Register. To assess generalizability to the wider CP population, Table S1 (online supporting information) shows characteristics of the 435 matched CP singleton cases and compares them to the 941 records from the eligible CP sample that were unable to be matched to a cFTS record. Nuchal translucency and CP There was little difference in the mean nuchal translucency MoMs between CP cases (geometric mean 0.96 [95% CI 0.94-0.98]) and non-CP controls (geometric mean 0.95 [95% CI 0.95-0.96]; I p i =0.62 for difference; Table 1). When PAPP-A and -hCG levels were considered together, CP pregnancies were 2.6 times more likely than non-CP pregnancies to have low levels of both PAPP-A and -hCG. [Extracted from the article]

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. We evaluated and compared best drooling response, side effects, and drug cessation rates using survival analysis, and the effect of baseline variables on the discontinuation rate using proportional hazards regression.Results: Among 110 participants (71 males, 39 females; mean age 8y 5mo [SD 4y 3mo], range 1y 11mo-18y 11mo), benzhexol, glycopyrrolate, and scopolamine were prescribed 81, 62, and 17 times respectively, with respective response rates of 85%, 75%, and 65%. Poor head control and poor oromotor function were predictive of poor response. Side effects frequently prompted drug cessation in males more than females (hazard ratio 1.8 [95% confidence interval 1.0-3.2], p=0.048). Glycopyrrolate had the fewest side effects.Interpretation: Benzhexol, glycopyrrolate, and scopolamine reduce drooling, but improvement is offset by adverse side effects. Overall, glycopyrrolate performs best.What This Paper Adds: In drooling, glycopyrrolate produced the greatest improvement with fewer side effects compared with benzhexol and scopolamine. Poor head control and poor oromotor function were associated with poor response. Medication side effects were common and often led to treatment discontinuation. Behavioural issues instigated cessation of benzhexol more often in males than females. [ABSTRACT FROM AUTHOR]

Aim: A population-based observational study design was used to describe the epidemiology of intellectual disability in cerebral palsy (CP) in terms of clinical and neuroimaging associations, and to report the impact of intellectual disability on utilization of health services and length of survival.Method: Population CP registry data were used to retrospectively assess the frequency of intellectual disability and strength of associations between intellectual disability and mobility, epilepsy, vision, hearing, communication, and neuroimaging patterns (n=1141). Data linkage was undertaken to assess usage of hospital inpatient and emergency department services. Survival analysis was performed in a 30-year birth cohort (n=3248).Results: Intellectual disability, present in 45% of the cohort, was associated with non-ambulation (47% vs 8%), later walking (mean 2y 7mo vs 1y 9mo), hypotonic (8% vs 1%) or dyskinetic (9% vs 5%) CP, a quadriplegic pattern of motor impairment (42% vs 5%), epilepsy (52% vs 12%), more emergency and multi-day hospital admissions, and reduced 35-year survival (96% vs 71%). Grey matter injuries (13% vs 6%), malformations (18% vs 6%), and miscellaneous neuroimaging patterns (12% vs 4%) were more common in people with intellectual disability.Interpretation: Intellectual disability adds substantially to the overall medical complexity in CP and may increase health and mortality disparities.What This Study Adds: Cerebral maldevelopments and grey matter injuries are associated with higher intellectual disability rates. Health care is more 'crisis-driven' and 'reactive' in children with co-occurring intellectual disability. Length of survival is reduced in individuals with CP and co-occurring intellectual disability. [ABSTRACT FROM AUTHOR]

Aim: The overall aim was to investigate the feasibility and utility of linking a cerebral palsy (CP) register to an administrative data set for health services research purposes. We sought to compare CP hospital admissions to general childhood population admissions, and identify factors associated with type and frequency of admissions in a CP cohort.Method: The CP register for Victoria, Australia was linked to the state's hospital admissions database. Data pertaining to the admissions of a CP cohort (n=1748) that took place between 2007 and 2014 were extracted. Population data were also obtained.Results: Overall, 80% of the CP cohort (n=1401) had at least admission between 2007 and 2014, accounting for 11 012 admissions or 1.5% of all admissions in their age group. Compared to general population admissions, CP admissions were more costly and more likely to be elective (66% vs 57%; p<0.001), medical (71% vs 57%; p<0.001), and to take place in metropolitan hospitals (92% vs 78%; p<0.001). Increased CP severity and complexity were associated with having more admissions and a higher proportion of admissions attributable to respiratory illness.Interpretation: By linking with administrative data sets, CP registers may be useful for health services research and inform health service delivery.

Aim: Limited information exists on the ability of children with cerebral palsy (CP) to ride a two-wheel bicycle, an activity that may improve health and participation. We aimed to describe bicycle-riding ability and variables associated with ability to ride in children with CP (Gross Motor Functional Classification System [GMFCS] levels I-II) compared with children with typical development.Method: This case-control study surveyed parents of 114 children with CP and 87 children with typical development aged 6 to 15 years (115 males, mean age 9y 11mo, standard deviation [SD] 2y 10mo). Kaplan-Meier methods were used to compare proportions able to ride at any given age between the two groups. Logistic regression was used to assess variables associated with ability to ride for children with CP and typical development separately.Results: The proportion of children with CP able to ride at each level of bicycle-riding ability was substantially lower at each age than peers with typical development (p<0.001). While most children with typical development were able to ride independently by 10 years of age, 51% of children with CP classified as GMFCS level I and 3% of those classified as GMFCS level II had obtained independent riding in the community by 15 years of age. Variables associated with ability to ride for children classified as GMFCS level I were age and parent-rated importance of their child being able to ride.Interpretation: Some independently ambulant children with CP can learn to ride a bicycle, in particular if they are classified as GMFCS level I. Variables associated with ability to ride deserve consideration in shaping future efforts for the majority of this population who are not yet able to ride. [ABSTRACT FROM AUTHOR]

Aim: Males typically outnumber females in cerebral palsy (CP) cohorts. To better understand this 'male disadvantage' and provide insight into causal pathways to CP, this study used 1983 to 2009 Australian CP and population birth cohorts to identify associations and trends with respect to biological sex and CP.Method: Within birth gestation groups, sex ratios were calculated to evaluate any male excess in the CP cohort compared with livebirths, neonatal deaths, neonatal mortality and survival rates, neonatal survivors, and CP rates in survivors. Sex- and gestation-specific trends in neonatal mortality, CP rates, and CP sex ratios were assessed by plotting their annual frequencies and fitting quadratic curves.Results: Over-representation of males in preterm live births partly explained the male excess in the CP cohort after preterm birth, especially at 28 to 31 weeks. Higher CP rates in male neonatal survivors also contributed to the male excess in CP, particularly at <28 and 37+ weeks. Higher neonatal mortality rates in males at all gestations had little impact on the CP sex ratio. There was no clearly discernible change over time in the CP sex ratio.Interpretation: Gestation-specific associations between sex and CP provide insight into causal pathways to CP and suggest sex-specific differences in response to neuroprotective strategies.

Aim: To describe the distribution of impairments among persons with cerebral palsy (CP) in a large Australian cohort.Method: Records of persons on the Australian Cerebral Palsy Register (ACPR) (n=3466) born from 1996 to 2005 were reviewed to extract year of birth, sex, CP subtype, Gross Motor Function Classification System (GMFCS) level, and impairments in vision, hearing, speech, intellect, and epilepsy. The distributions of GMFCS levels and CP subtype were plotted, and the proportions of each level of impairment were tabulated and presented as stacked graphs within the GMFCS and CP subtype distributions.Results: The proportions of persons with CP with each associated impairment increased with increasing GMFCS level. Compared with other spastic CP subtypes, individuals with spastic quadriplegia had higher frequencies of all associated impairments. Other than epilepsy, which was most prevalent in persons with spastic quadriplegia (53%), all impairments were most frequent in non-spastic CP subtypes. Hearing impairment was recorded for 21% of persons with dyskinesia whereas the hypotonic subtype had the highest prevalence of visual impairment (57%), intellectual impairment (90%), and speech impairment (95%).Interpretation: Distributions of associated impairments across all GMFCS levels and CP subtypes in a large cohort are presented in formats suitable for clinical use and discussion with families.

Aim: Our aim was to build on previous research indicating that rates of cerebral palsy (CP) in the Australian state of Victoria are declining, and examine whether severity of impairments is also decreasing.Method: Data on individuals with CP were extracted from the Victorian Cerebral Palsy Register for birth years 1983 to 2009. The yearly rates of dichotomized categories for gross motor function, motor laterality, intellectual impairment, and epilepsy per 1000 neonatal survivors and proportions in the CP cohort were tabulated and plotted by birth gestation. Linear regression modelling was used to fit prediction curves; likelihood ratio tests were used to test for differences in trends between impairment severity groups.Results: Since the mid-1990s, CP rates declined in neonatal survivors of birth at all gestations. Our data suggest that the decreasing CP rates were associated with relatively greater decreases in the rates of Gross Motor Function Classification System levels III to V, bilateral CP, epilepsy, and intellectual impairment (all p<0.005). Some variation was seen between birth gestation groups.Interpretation: Declines in rates of CP of all levels of severity and complexity from the mid-1990s provides 'real-world' support for the effectiveness of concurrent neuroprotective strategies and continual innovation in perinatal practices.

Aims: In a population cohort of children with grey matter injury (GMI) and cerebral palsy (CP), we aimed to describe and classify magnetic resonance imaging characteristics specific to GMI, and to identify key structure-function associations that serve as a basis for rating GMI in clinically relevant ways. Method: Symmetry, extent of cerebral injury, and pathological pattern for 54 children (37 males, 17 females) with CP and a predominant GMI pattern on chronic-phase magnetic resonance imaging were related to gross motor function, motor type and topography, epilepsy, intellectual disability, blindness, and deafness. Results: Relative to mild GMI where there was no pallidal abnormality, severe GMI, comprising pallidal abnormality alone or in conjunction with other deep nuclear and generalized cortical-subcortical involvement, was strongly associated with Gross Motor Function Classification System levels IV to V (OR 35.7 [95% CI 3.5, 368.8]). Involvement of the basal ganglia was associated with non-spastic/mixed motor types, but predominantly where cortical-subcortical grey and white matter involvement was not extensive. The prevalence of epilepsy was highest where there was diffuse cortical-subcortical involvement and white matter loss. Interpretation: Better understanding of structure-function relationships in CP and GMI, and how to rate the severity of GMI, will be helpful in the clinical context and also as a basis for investigation of causal pathways in CP.

Background. There is short-term evidence for treatment of cervicogenic dizziness with Mulligan sustained natural apophyseal glides (SNAGs) but no evidence for treatment with Maitland mobilizations. Objective. The purpose of this study was to compare the effectiveness of SNAGs and Maitland mobilizations for cervicogenic dizziness. Design. A double-blind, parallel-arm randomized controlled trial was conducted. Setting. The study was conducted at a university in Newcastle, Australia. Participants. Eighty-six people with cervicogenic dizziness were the study participants. Interventions. Included participants were randomly allocated to receive 1 of 3 interventions: Mulligan SNAGs (including self-administered SNAGs), Maitland mobilizations plus range-of-motion exercises, or placebo. Measurements. The primary outcome measure was intensity of dizziness. Other outcome measures were: frequency of dizziness, the Dizziness Handicap Inventory (DHI), intensity of pain, and global perceived effect (GPE). Results. Both manual therapy groups had reduced dizziness intensity and frequency posttreatment and at 12 weeks compared with baseline. There was no change in the placebo group. Both manual therapy groups had less dizziness intensity posttreatment (SNAGs: mean difference=-20.7, 95% confidence interval [95% CI]=-33.6, -7.7; mobilizations: mean difference=-15.2, 95% CI=-27.9, -2.4) and at 12 weeks (SNAGs: mean difference=-18.4, 95% CI=-31.3, -5.4; mobilizations: mean difference=-14.4, 95% CI=-27.4, -1.5) compared with the placebo group. Compared with the placebo group, both the SNAG and Maitland mobilization groups had less frequency of dizziness at 12 weeks. There were no differences between the 2 manual therapy interventions for these dizziness measures. For DHI and pain, all 3 groups improved posttreatment and at 12 weeks. Both manual therapy groups reported a higher GPE compared with the placebo group. There were no treatment-related adverse effects lasting longer than 24 hours. Limitations. The therapist performing the interventions was not blind to group allocation. Conclusions. Both SNAGs and Maitland mobilizations provide comparable immediate and sustained (12 weeks) reductions in intensity and frequency of chronic cervicogenic dizziness. INSET: The Bottom Line.

Aim The aim of this study was to review the distribution of neuroimaging findings from a contemporary population cohort of individuals with cerebral palsy ( CP) and to facilitate standardization of imaging classification. Method Publications from 1995 to 2012 reporting imaging findings in population cohorts were selected through a literature search, and review of the titles, abstracts, and content of studies. Relevant data were extracted, including unpublished data from Victoria, Australia. The proportions for each imaging pattern were tabulated, and heterogeneity was assessed for all individuals with CP, and for subgroups based on gestational age, CP subtype, and Gross Motor Function Classification System level. Results Studies from three geographic regions met the inclusion criteria for individuals with CP, and two additional studies reported on specific CP subtypes. Brain abnormalities were observed in 86% of scans, but were observed least often in children with ataxia (24-57%). White matter injury was the most common imaging pattern (19-45%), although the proportions showed high heterogeneity. Additional patterns were grey matter injury (21%), focal vascular insults (10%), malformations (11%), and miscellaneous findings (4-22%). Interpretation This review suggests areas where further dialogue will facilitate progress towards standardization of neuroimaging classification. Standardization will enable future collaborations aimed at exploring the relationships among magnetic resonance imaging patterns, risk factors, and clinical outcomes, and, ultimately, lead to better understanding of causal pathways and opportunities for prevention.

Aim The aim of this study was to describe the distribution of magnetic resonance imaging ( MRI) patterns in a large population sample of children with cerebral palsy ( CP) and to examine associations between MRI patterns, and antenatal and perinatal variables. Method Data were retrieved from the Victorian CP Register for 884 children (527 males, 357 females) born between 1999 and 2006. Postneonatal MRI was classified for 594 children. For 563 children (329 males, 234 females) for whom classification was to a single MRI pattern, the frequency of each variable was compared between patterns and with the population frequency. Results White matter injury was the most common MRI pattern (45%), followed by grey matter injury (14%), normal imaging (13%), malformations (10%), focal vascular insults (9%), and miscellaneous patterns (7%). Parity, birth gestation, level of neonatal care, Apgar score, and time to established respiration varied between MRI patterns ( p<0.01). Nulliparity was most strongly associated with focal vascular insults, whereas multiparity was associated only with malformations. Grey matter injury was not associated with birth in a tertiary unit, but was strongly associated with severe perinatal compromise. The frequency of neonatal seizures and of nursery admissions was lowest among children with malformations. Interpretation As known risk factors for CP are differentially associated with specific MRI patterns, future exploration of causal pathways might be facilitated when performed in pathogenically defined groups.

Aim To establish a prevalence estimate for drooling and explore factors associated with drooling in a population sample of children with cerebral palsy (CP) aged 7 to 14 years living in Victoria, Australia. Method A self-report questionnaire was used to collect data on drooling from parents of children born between 1996 and 2001, and registered with the Victorian Cerebral Palsy Register. Results A total of 385 children (231 males, 154 females; mean age 10y 9mo [SD 1y 7mo], range 8-14y) were studied. The clinical type and distribution of CP were spastic (341), ataxic (16), dyskinetic (17), hypotonic (10), and unknown (1). Distribution in Gross Motor Function Classification System (GMFCS) levels was I (103), II (98), III (52), IV (63), V (61), and unknown (8). After adjustment for topographical pattern of motor impairment and GMFCS level, 40% were reported to have experienced drooling between 4 years of age and the time of completing the questionnaire. A significantly higher prevalence of drooling was found in children with poor gross motor function and in those with more severe presentations of CP, including poor head control, difficulty with eating, and inability to sustain lip closure ( p<0.001 for each). Drooling was shown to be significantly associated with both intellectual disability and epilepsy in this group of children ( p<0.001 for both). Interpretation With a prevalence of 40%, drooling is an important comorbidity in CP. It was considered severe in 15% of children. Poor oromotor function was associated with drooling and could be the target of interventions for this under-researched problem. [ABSTRACT FROM AUTHOR]

The article presents information on the decriminalization of pleasure-seeking behavior by challenging the criminal law in the U.S. It states that medicalization in the context of sexual intimacy can help in understanding the working of medicalization and prepare models to understand drug use. It discusses several Supreme Court cases including Eisenstadt v. Baird, Roe v. Wade and Carey v. Population Services International that paved the way for access to contraception and abortion. It mentions that biological necessity does not discriminate roles of pleasure in sex and drugs.

Aim This study used data collected prospectively since 1986 from a population-based cerebral palsy registry to explore the rates, predictors, trends, and causes of mortality for individuals born in Victoria, Australia, between 1970 and 2004. Method Data were extracted for 3507 individuals (1972 males; 1535 females). The probability of survival before 31 May 2010 was determined using the Kaplan-Meier method; age-specific mortality rates were calculated per 1000 person-years and related to population rates. Using Cox proportional hazards regression, relative risks of mortality were estimated for different categories of chosen demographic and clinical variables. Causes were tabulated according to the direct cause of death. Results There were 418 deaths. Crude mortality was 20% at the age of 40 years. Relative to the population, mortality was highest in children aged under 15 years and decreased to twice the population rate at the age of 35 years. The strongest independent predictor of mortality was no independent ambulation (adjusted hazard ratio 6.2 [95% confidence interval 3.3-11.8]); additional predictors were severe intellectual impairment (3.0 [1.7-5.2]), epilepsy (1.4 [1.1-1.9]), deafness (2.6 [1.4-4.7]), and term birth (1.8 [1.3-2.4]). No improvement in survival was seen over time (unadjusted hazard ratio 1.00 [95% CI 0.99-1.01]). Respiratory causes were the most common direct causes of death. Interpretation Rates, predictors, and causes of death for individuals with cerebral palsy in Victoria were similar to those found in other population cohorts. Lack of improvement in survival since 1970 was an unexpected finding that warrants further investigation. [ABSTRACT FROM AUTHOR]

Background: Cervicogenic dizziness is a disabling condition characterised by postural unsteadiness that is aggravated by cervical spine movements and associated with a painful and/or stiff neck. Two manual therapy treatments (Mulligan's Sustained Natural Apophyseal Glides (SNAGs) and Maitland's passive joint mobilisations) are used by physiotherapists to treat this condition but there is little evidence from randomised controlled trials to support their use. The aim of this study is to conduct a randomised controlled trial to compare these two forms of manual therapy (Mulligan glides and Maitland mobilisations) to each other and to a placebo in reducing symptoms of cervicogenic dizziness in the longer term and to conduct an economic evaluation of the interventions. Methods: Participants with symptoms of dizziness described as imbalance, together with a painful and/or stiff neck will be recruited via media releases, advertisements and mail-outs to medical practitioners in the Hunter region of NSW, Australia. Potential participants will be screened by a physiotherapist and a neurologist to rule out other causes of their dizziness. Once diagnosed with cervciogenic dizziness, 90 participants will be randomly allocated to one of three groups: Maitland mobilisations plus range-of-motion exercises, Mulligan SNAGs plus self-SNAG exercises or placebo. Participants will receive two to six treatments over six weeks. The trial will have unblended treatment but blinded outcome assessments. Assessments will occur at baseline, post-treatment, six weeks, 12 weeks, six months and 12 months post treatment. The primary outcome will be intensity of dizziness. Other outcome measures will be frequency of dizziness, disability, intensity of cervical pain, cervical range of motion, balance, head repositioning, adverse effects and treatment satisfaction. Economic outcomes will also be collected. Discussion: This paper describes the methods for a randomised controlled trial to evaluate the effectiveness of two manual therapy techniques in the treatment of people with cervicogenic dizziness for which there is limited established evidence-based treatment.

Aim The aim of this study was to describe the distribution of motor severity levels and temporal trends in an Australian population cohort and to review the distribution of Gross Motor Function Classification System (GMFCS) levels across cerebral palsy (CP) registries worldwide. Methods Data were extracted from the Victorian Cerebral Palsy Register for 3312 individuals (1852 males, 1460 females; mean age 21y 2mo [SD 9y 6mo]) with non-postneonatally acquired CP, born between 1970 and 2003. The proportions of each motor severity level were calculated and logistic regression analyses were used to assess trends over time. A systematic review of the literature was undertaken and GMFCS data were extracted based on previously devised criteria. The proportions were plotted and the degree of heterogeneity was assessed for each level. Results Population data from Victoria suggested a proportional increase in mild motor impairment (GMFCS levels I/II) from 54% of all cases of CP in the 1970s to 61% in the 2000s. For nine CP registries worldwide, the mean proportions of each GMFCS level, from level I to V, were 34.2%, 25.6%, 11.5%, 13.7%, and 15.6% respectively. There was substantial heterogeneity between registries for all levels except level III. Interpretation Despite the usefulness and reported reliability of the GMFCS, substantial variability was found in the distribution of GMFCS levels between population registries, particularly between levels I and II, suggesting greater classification uncertainty between these levels. Further research would be useful to determine whether routine collection of extra clinical information may facilitate more reliable classification. [ABSTRACT FROM AUTHOR]

Aim The aims of this study were to estimate the frequency of hearing loss in children with cerebral palsy (CP), to examine factors associated with hearing loss, and to describe aspects of hearing in a population sample of children with CP and hearing loss. Method A systematic review of the international literature was undertaken, and data on the frequency of hearing loss or severe hearing loss were extracted from 14 data sets based on previously devised criteria. Six hundred and eight-five children with CP (406 males, 279 females) born in Victoria, Australia, between 1999 and 2004 were identified from the Victorian Cerebral Palsy Register. Children were included if they had an established post neonatal cause for their CP before the age of 2 years. Additional information was collected on 48 children with documented hearing loss based on a four-tone pure tone average in the better ear. Results There was considerable variation in the definitions and proportions of hearing loss (range 4-13%) and severe hearing loss (range 2-12%) reported by CP registries in developed countries. In Victoria, 7% of individuals with CP had bilateral hearing loss of a moderate to profound degree, whereas the subgroup with a severe-profound degree of loss constituted 3% to 4% of the CP population. Interpretation These population-based data are likely to more accurately reflect the true frequency of defined hearing loss in children with CP than previous reviews. [ABSTRACT FROM AUTHOR]

Aim The aim of this study was to assess overall and gestational age-specific trends in the rate of cerebral palsy (CP) in Victoria, Australia, and to compare these findings with other population data. Method Individuals born in Victoria from 1970 to 2004 with non-postneonatally acquired CP were identified from a population register; 3491 were included in the study (1963 males, 1528 females). After a literature review, comparison data were extracted from publications using previously devised inclusion criteria. Rates were calculated per 1000 live births for all CP and by gestational age group: these were tabulated and plotted by year of birth. Results Data from nine registries, including the Victorian register, showed an increase in the rates of CP over the 1970s and 1980s, consistently seen in extremely preterm (<28wks) survivors but also in those born at term (≥37wks). Since the early 1990s, CP rates either stabilized or decreased, particularly for children born extremely preterm. Interpretation Increases in the rates of CP during the 1970s and 1980s are in part because of the increasing survival of extremely preterm infants that occurred without a concomitant improvement in neurological outcomes. Evidence from population samples now suggests that this trend has been reversed since the mid- to late 1990s. [ABSTRACT FROM AUTHOR]

The aim of this study was to describe the distribution of types of motor disorder (motor type) in a population-based registry of children with cerebral palsy (CP), to examine any trends in motor type distribution over time, and to make comparisons with other populations. Individuals born in Victoria, Australia, between 1970 and 2003 with congenital CP were identified from the Victorian Cerebral Palsy Register, 3297 of whom were included in the study (1840 males, 1457 females). Those who had a hypotonic motor type, those whose brain abnormality was believed to have developed after 28 days of life, and those with missing data were excluded from the study. The proportions of each motor type were calculated and plotted by year of birth. Logistic regression analyses were used to assess the mean change in odds per year of birth. A systematic review of the international literature was undertaken and comparison data were extracted based on previously devised criteria. The degree of heterogeneity was assessed and comparisons were made according to geographical region and reporting period. In Victoria, the predominant motor types for individuals with CP born between 1970 and 2003 were spasticity (91%), ataxia (5%), and dyskinesia (4%). There was no clear trend for any motor type over time. The mean proportions from two other large data sets were similar but there was considerable heterogeneity between 29 individual CP registries, mainly because of differences in the classification of mixed motor types. A more objective method for determining the predominant motor type is required to make the classification of motor type in CP more consistent and reliable. [ABSTRACT FROM AUTHOR]

Aim The aim of this study was to describe the frequency, risk factors, manifestations, and outcome of epilepsy in children with hemiplegic cerebral palsy (CP) due to perinatal arterial ischaemic stroke (AIS). Method The study group comprised 63 participants (41 males, 22 females) from a population-based CP register whose brain imaging showed perinatal AIS. Information collected included occurrence of neonatal seizures, family history of epilepsy, motor function and epilepsy onset, treatment, and outcome. Electroclinical findings were classified according to seizure semiology, seizure type, and epilepsy syndrome. Results Mean age of participants at the time of study was 10 years 6 months (SD 4y 7mo, range 4-20y). Gross Motor Function Classification System levels I and II were reported in 96% of participants, and Manual Ability Classification System levels I and II were reported in 79% of children. Thirty-four children (54%) developed epilepsy. Term delivery and more severe motor impairment were associated with epilepsy, but neonatal seizures and family history of epilepsy were not. Initial seizures were epileptic spasms, focal seizures, or myoclonic seizures. Focal seizure semiology suggested Rolandic or occipital seizure origin in the majority of children. Focal epileptic discharges in children with focal seizures had features of idiopathic partial epilepsy. Only 15% of children had active epilepsy 10 years after onset. Interpretation Despite a high incidence of epilepsy in children with hemiplegic CP due to AIS, the prognosis for seizure remission is good. Many children have clinical features, electroencephalography findings, and remission typical of idiopathic partial epilepsy. [ABSTRACT FROM AUTHOR]

Aim To determine whether assisted reproductive technologies (ART) were more likely to be the method of conception in singletons with cerebral palsy (CP) than in those without CP. Method Singletons with CP born between 1991 and 2004 were selected from the Victorian Cerebral Palsy Register and matched for birth year to two singletons randomly selected from the Victorian Perinatal Data Collection Unit. Data from both sources were linked to records from three ART centres. Conditional logistic regression was used to assess the association between CP and aspects of conception using ART. Multivariate models were adjusted for parity, previous miscarriages, sex, gestational age, birthweight, and weight for gestational age. Results We identified 1241 singletons with CP (males n=721 [58%], females n=420 [42/100]; motor type: spastic [87%; unilateral 37%; bilateral 63%], ataxic n=60 [5/100], dyskinetic n=46 [4/100], hypotonic n=29 [2/100], unknown n=25 [2/100]. Gross Motor Function Classification System levels were I n=363 [29/100], II n=297 [24/100], III n=137 [11/100], IV n=160 [13/100], V n=192 [15/100], and unknown n=92 [7/100]). Sixteen (1.3/100) of the children with CP and 25 (1.0/100) of 2482 children without CP were conceived using ART. There was no significant increase in the odds of children with CP being conceived using ART (adjusted odds ratio 1.19, 95% confidence interval (CI) 0.63, 2.24) nor in the odds of them being conceived by a subfertile couple without ART (adjusted odds ratio 2.7, 95% CI 0.87, 8.36). Interpretation Singleton conception using ART is not strongly associated with an increased risk of CP. [ABSTRACT FROM AUTHOR]

Aim To describe the development and clinimetric properties of a new scale to evaluate changes in the impact of drooling in children with developmental disabilities. Method After examining the properties of potential items, 10 items were retained for inclusion in the final Drooling Impact Scale. The clinimetric properties of the scale were evaluated using data from two convenience samples of children attending a saliva-control clinic: a stable group ( n=31, 22 males, nine females; mean age 10y 7mo, SD 4y 5mo, range 3y 6mo–18y 3mo; cerebral palsy [CP] n=17, intellectual disability n=10; non-ambulatory n=13, nonverbal n=12) and an intervention group ( n=49, 29 males, 20 females; mean age 11y, SD 3y 6mo, range 3y 4mo–16y 10mo; CP n=31, intellectual disability n=15; non-ambulatory n=27, nonverbal n=28). To assess validity, changes in scores on the Drooling Impact Scale over time were compared with a carer’s global rating of change using Pearson’s correlations and t-tests. A concordance correlation coefficient was used to compute the level of agreement between assessments 1 month apart in stable children. Effect size, standardized response mean, Guyatt responsiveness statistic, and an unpaired t-test were used to estimate responsiveness. Results The correlation between the global rating and change in Drooling Impact Scale scores was 0.69 ( p<0.001). The concordance correlation coefficient was 0.85. An effect size of 1.8, standardized response mean of 1.5, Guyatt responsiveness statistic of 1.4, and mean group difference of 23.5 (95% confidence interval 17.4–29.6) were obtained. Interpretation The Drooling Impact Scale is a valid and reliable subjective measure that is responsive to change. [ABSTRACT FROM AUTHOR]

Patients with cervicogenic dizziness (CGD) present with dizziness, cervical spine dysfunctions, and postural imbalance, symptoms that can significantly impact their daily functioning. To provide evidence-based recommendations for the management of patients with CGD. Three databases were searched for randomized controlled trials (RCTs) (last search 15 May 2021). Outcome measures included dizziness, cervical spine, and balance parameters. Cochrane standard methodological procedures were used and included the RoB 2.0 and GRADE. Where possible, RCTs were pooled for meta-analysis. Thirteen RCTs (n = 898 patients) of high (two RCTs), moderate (five RCTs), and low (six RCTs) methodological quality were analyzed. Six RCTs were included in the meta-analysis. Only three RCTs specified the cause of CGD. They showed inconsistent findings for the effectiveness of exercise therapy in patients with traumatic CGD. Manual therapy and manual therapy combined with exercise therapy may reduce CGD, cervical spine, and balance dysfunctions. There is moderate quality of evidence that manual therapy reduces CGD, cervical spine, and balance symptoms. When manual therapy is combined with exercise therapy, the positive effect on CGD, cervical spine, and balance symptoms is even stronger. However, the quality of the evidence here is very low.

Burnout syndrome (BOS) in academic physicians is a psychological state resulting from prolonged exposure to job stressors. It leads to a decline in overall job performance, which could result in misjudgment and serious clinical errors. The current study identifies the prevalence, as well as the potential demographic and workload variables that contribute significantly to BOS in academic clinicians. We distributed a modified version of the Maslach Burnout Inventory (MBI) scale to the academic clinicians in our institution; 326/900 responded, with 56.21% male and 43.46% female. The MBI scale comprised of three dimensions of burnout: emotional exhaustion (EE), depersonalization (DP), and personal accomplishment (PA). Higher scores in EE and DP and lower scores in PA were associated with a higher risk for burnout. In considering the work-life of academic clinicians, this study used a modified version of the MBI to reflect three hypothesized sources of burnout: interactions with students/trainees, interactions with patients, and interactions with administration, as reflected in these three dimensions. Along both the EE and DP dimensions of the MBI, burnout was highest for interactions with administration (51% and 44.8%), moderate for interactions with patients (26.4% and 34.5%), and lowest for interactions with students (11.7% and 9.8%). The highest scores along the personal accomplishment component was found for interactions with students and patients (33.7% and 33.4%). Regression analyses identified several factors associated with higher scores on the EE and DP scales: younger age, surgical specialty, low academic rank, academic main practice, female gender, numerous night shifts, and living alone. Furthermore, higher patient volume contributed significantly to the increasing PA. This study suggests that administrative interaction contributes significantly to burnout amongst physicians, followed by patient care and trainees. Furthermore, surgeons, females, single, early career, and younger faculty staff members are at higher risk of suffering from burnout. Further studies are needed to characterize the nature of administrative interactions that contribute to burnout and to solidify other contributing variables. [ABSTRACT FROM AUTHOR]

Aim: The aims of this study were to estimate the proportion of emergency department presentations attributable to children with cerebral palsy (CP), investigate the frequency of emergency department presentations in a CP cohort, and compare emergency department presentations among children with CP with those of other children.Method: This was a retrospective cohort study. The Victorian Cerebral Palsy Register was linked to the Victorian Emergency Minimum Dataset. Data on emergency department presentations for the CP cohort occurring between 2007 and 2014 and population control data were obtained.Results: The CP cohort (n=1748) had 7015 emergency department presentations during the 7-year period, accounting for 0.4% of the 1.69 million age-specific presentations during that time. The number of annual presentations per 1000 children rose with increasing CP severity. Compared with presentations among the general population, higher proportions of presentations among the CP cohort were preceded by ambulance arrivals (27% vs 8%), triaged as urgent (66% vs 32%), and required hospital admission (38% vs 12%).Interpretation: The marked differences in presentations between the CP cohort and the general population in the proportions that were urgent and required ambulance arrivals and hospital admissions was an important finding. Strategies to ensure appropriate use of services, including encouragement to seek earlier assistance from primary care providers, may prevent problems escalating to the need for urgent care.What This Paper Adds: Children with cerebral palsy (CP) account for 0.4% of childhood emergency department presentations. More emergency department presentations among children with CP require ambulance arrival. More CP emergency department presentations are urgent and require hospital admission. Traditional emergency department triage scales seem less accurate for this group. [ABSTRACT FROM AUTHOR]

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. Mortality rates were calculated per 1000 person‐years using age strata and compared with population mortality rates to produce mortality ratios. Cox proportional hazards regression was used to calculate hazard ratios for selected demographic and clinical characteristics and to estimate the effect of birth epoch on 15‐year survival. Results: There were 666 recorded deaths. Compared to the general population, mortality was higher for all persons with CP and highest for children aged 1 to 15 years (45–62 times). We observed 35% improvement in the probability of survival to 15 years for births in the 2000s relative to the 1970s (hazard ratio 0.65, 95% confidence interval [CI] 0.49, 0.86), but only 4% improvement for the subgroup with complex CP (hazard ratio 0.96, 95% CI 0.69, 1.33). Interpretation: The observed improvements in survival for those born in the 2000s is likely related predominantly to a proportional reduction in complex CP within the cohort. What this paper adds: Length of survival improved for Australians with cerebral palsy (CP) born this millennium.Improved survival was mainly because of a proportional reduction in complex CP.A small improvement in length of survival was seen for children with complex CP.

Seizures occur in approximately one-third of children with cerebral palsy. This study aimed to determine epilepsy syndromes in children with seizures and cerebral palsy due to vascular injury, anticipating that this would inform treatment and prognosis. We studied a population-based cohort of children with cerebral palsy due to prenatal or perinatal vascular injuries, born 1999–2006. Each child's MRI was reviewed to characterize patterns of grey and white matter injury. Children with syndromic or likely genetic causes of cerebral palsy were excluded, given their inherent association with epilepsy and our aim to study a homogeneous cohort of classical cerebral palsy. Chart review, parent interview and EEGs were used to determine epilepsy syndromes and seizure outcomes. Of 256 children, 93 (36%) had one or more febrile or afebrile seizures beyond the neonatal period and 87 (34%) had epilepsy. Children with seizures were more likely to have had neonatal seizures, have spastic quadriplegic cerebral palsy and function within Gross Motor Function Classification System level IV or V. Fifty-six (60%) children with seizures had electroclinical features of a self-limited focal epilepsy of childhood; we diagnosed these children with a self-limited focal epilepsy-variant given the current International League Against Epilepsy classification precludes a diagnosis of self-limited focal epilepsy in children with a brain lesion. Other epilepsy syndromes were focal epilepsy—not otherwise specified in 28, infantile spasms syndrome in 11, Lennox–Gastaut syndrome in three, genetic generalized epilepsies in two and febrile seizures in nine. No epilepsy syndrome could be assigned in seven children with no EEG. Twenty-one changed syndrome classification during childhood. Self-limited focal epilepsy-variant usually manifested with a mix of autonomic and brachio-facial motor features, and occipital and/or centro-temporal spikes on EEG. Of those with self-limited focal epilepsy-variant, 42/56 (75%) had not had a seizure for >2 years. Favourable seizure outcomes were also seen in some children with infantile spasms syndrome and focal epilepsy-not otherwise specified. Of the 93 children with seizures, at last follow-up (mean age 15 years), 61/91 (67%) had not had a seizure in >2 years. Children with cerebral palsy and seizures can be assigned specific epilepsy syndrome diagnoses typically reserved for normally developing children, those syndromes commonly being age-dependent and self-limited. Compared to typically developing children with epilepsy, self-limited focal epilepsy-variant occurs much more commonly in children with cerebral palsy and epilepsy. These findings have important implications for treatment and prognosis of epilepsy in cerebral palsy, and research into pathogenesis of self-limited focal epilepsy. [ABSTRACT FROM AUTHOR]

Aim: To describe post‐neonatally acquired (PNN) cerebral palsy (CP) in terms of temporal trends in prevalence, clinical and sociodemographic profiles, known causes and associations between causes, and sociodemographic variables. Method: Numerator data, a count of children with PNN‐CP confirmed at 5 years of age (n = 523), was drawn from two Australian state CP registers (birth years 1973–2012). Poisson regression was used to investigate temporal trends in the prevalence of PNN‐CP by 5‐year intervals, calculated per 10 000 live births. Using data from all state and territory Australian CP registers (n = 469), distributions of clinical characteristics, PNN‐CP causes, and sociodemographic factors were tabulated (birth years 1995–2012). χ2 and logistic regression analyses were used to assess associations between sociodemographic profile, Australian reference data, and known causes. Results: A significant temporal decline in PNN‐CP in Victoria (p = 0.047) and Western Australia (p = 0.033) was observed. The most common proximal causes of PNN‐CP were cerebrovascular accidents (34%, n = 158), infection (25%, n = 117), and non‐accidental injuries (12%, n = 58). Children born to teenage mothers, Aboriginal and/or Torres Strait Islander mothers, or children born in remote areas were over‐represented in this cohort compared with reference data (all p ≤ 0.001). Infectious causes were strongly associated with teenage motherhood (odds ratio 3.0 [95% confidence interval 1.1–8.2], p = 0.028) and remote living (odds ratio 4.5 [95% confidence interval 2.0–10.2], p < 0.001). Interpretation: Although prevalence of PNN‐CP has declined, the over‐representation of priority populations, and the relative severity of a condition that is largely preventable, suggest the need for more specific primary preventive measures and support. What this paper adds: Prevalence of post‐neonatally acquired (PNN) cerebral palsy (CP) in Australia significantly declined between 1973 and 2012.Cerebrovascular accidents are the most common proximal cause of PNN‐CP.Children born in remote areas are at greater risk of PNN‐CP.

Background: Cervicogenic dizziness is a disabling condition characterised by postural unsteadiness that is aggravated by cervical spine movements and associated with a painful and/or stiff neck. Two manual therapy treatments (Mulligan's Sustained Natural Apophyseal Glides (SNAGs) and Maitland's passive joint mobilisations) are used by physiotherapists to treat this condition but there is little evidence from randomised controlled trials to support their use. The aim of this study is to conduct a randomised controlled trial to compare these two forms of manual therapy (Mulligan glides and Maitland mobilisations) to each other and to a placebo in reducing symptoms of cervicogenic dizziness in the longer term and to conduct an economic evaluation of the interventions.Methods: Participants with symptoms of dizziness described as imbalance, together with a painful and/or stiff neck will be recruited via media releases, advertisements and mail-outs to medical practitioners in the Hunter region of NSW, Australia. Potential participants will be screened by a physiotherapist and a neurologist to rule out other causes of their dizziness. Once diagnosed with cervciogenic dizziness, 90 participants will be randomly allocated to one of three groups: Maitland mobilisations plus range-of-motion exercises, Mulligan SNAGs plus self-SNAG exercises or placebo. Participants will receive two to six treatments over six weeks. The trial will have unblinded treatment but blinded outcome assessments. Assessments will occur at baseline, post-treatment, six weeks, 12 weeks, six months and 12 months post treatment. The primary outcome will be intensity of dizziness. Other outcome measures will be frequency of dizziness, disability, intensity of cervical pain, cervical range of motion, balance, head repositioning, adverse effects and treatment satisfaction. Economic outcomes will also be collected.Discussion: This paper describes the methods for a randomised controlled trial to evaluate the effectiveness of two manual therapy techniques in the treatment of people with cervicogenic dizziness for which there is limited established evidence-based treatment.Trial Registration: ACTRN12611000073909.

Purpose Traumatic diaphragmatic rupture (TDR) is an uncommon injury that can be associated with significant morbidity if not detected and treated in a timely manner. The purpose of our study was to evaluate the diagnostic accuracy of 64-slice multidetector computed tomography (64-MDCT) for the detection of TDR in patients at our level 1 trauma centre. Methods We used our hospital's trauma registry to identify patients with a diagnosis of TDR from January 1, 2008, to December 31, 2012. Only patients with a 64-MDCT scan at presentation who subsequently underwent laparotomy/laparoscopy were included in the study cohort. Using surgical findings as the gold standard, the accuracy of the prospective radiology reports was analyzed. Results Of the 3225 trauma patients who presented to our institution, 38 (1.2%) had a TDR. Fourteen of the 38 were excluded as they did not have MDCT before surgery. The study cohort consisted of 20 males and 4 females with a median age of 34.5 years and a median Injury Severity Score (ISS90) of 26. Fifteen had blunt trauma while 9 had a penetrating injury. The overall sensitivity of the radiology reports was 66.7% (95% confidence interval [CI]: 46.7%-82.0%), specificity was 100% (95% CI: 94.1%-100%), positive predictive value was 100% (95% CI: 80.6%-100%), negative predictive value was 88.4% (95% CI: 78.8%-94.0%), and accuracy was 90.6% (95% CI: 82.5%-95.2%). However, only 3 of 9 patients with penetrating injury had a correct preoperative diagnosis. Two of the 6 missed penetrating trauma cases had only indirect signs of injury. Conclusions The detection of TDR in trauma patients on 64-MDCT can be improved, especially in patients presenting with penetrating injury. A careful search for subtle diaphragmatic defects and indirect evidence of injury is important to avoid missing the diagnosis. [ABSTRACT FROM AUTHOR]
