Abstract
Children diagnosed with metopic synostosis (MS) commonly experience poor neuropsychological outcomes, with research suggesting that children whose MS is managed conservatively (without surgery) potentially having worse outcomes than their operated peers. However, studies of children whose MS was managed conservatively are scarce. This study therefore examined the cognitive, behavioral, and psychological functioning of children/adults with conservatively managed MS (N = 38) and compares their outcomes to individually matched healthy controls (N = 38) of the same age and sex (matched-pairs design) from the general community. Age-appropriate, validated assessments measuring general cognition, verbal and visuospatial ability, attention and working memory, executive functioning, behavior, depression, anxiety, and satisfaction with appearance were utilized. Group differences were estimated using linear regression for (a) the overall sample and (b) by broad developmental stages: 2&3 yrs; ≥6-≤17. Moderate to large negative effects (g = -0.38 to -1.30) were evident before controlling for socio-economic status (SES), with the MS group performing significantly worse on 8 out of the 10 cognitive domains (general cognition, visuospatial ability, working memory, information processing, executive functioning: semantic & initial letter verbal fluency, switching, inhibition+switching). However, only initial letter verbal fluency (g = -0.99) and switching (g = -1.19) remained significant after adjusting for SES. The MS group displayed more behavioral problems, although this was not significant. Depression, anxiety, and satisfaction with appearance did not differ between the groups. Regular monitoring of cognitive functioning, particularly executive functioning, should be undertaken for those with conservatively managed MS.

Abstract
Impaired cerebellar development is an important determinant of adverse motor and cognitive outcomes in very preterm (VPT) infants. However, longitudinal MRI studies investigating cerebellar maturation from birth through childhood and associated neurodevelopmental outcomes are lacking. We aimed to compare cerebellar volume and growth from term-equivalent age (TEA) to 7 years between VPT (< 30 weeks' gestation or < 1250 g) and full-term children; and to assess the association between these measures, perinatal factors, and 7-year outcomes in VPT children, and whether these relationships varied by sex. In a prospective cohort study of 224 VPT and 46 full-term infants, cerebellar volumes were measured on MRI at TEA and 7 years. Useable data at either time-point were collected for 207 VPT and 43 full-term children. Cerebellar growth from TEA to 7 years was compared between VPT and full-term children. Associations with perinatal factors and 7-year outcomes were investigated in VPT children. VPT children had smaller TEA and 7-year volumes and reduced growth. Perinatal factors were associated with smaller cerebellar volume and growth between TEA and 7 years, namely, postnatal corticosteroids for TEA volume, and female sex, earlier birth gestation, white and deep nuclear gray matter injury for 7-year volume and growth. Smaller TEA and 7-year volumes, and reduced growth were associated with poorer 7-year IQ, language, and motor function, with differential relationships observed for male and female children. Our findings indicate that cerebellar growth from TEA to 7 years is impaired in VPT children and relates to early perinatal factors and 7-year outcomes.

Abstract
BACKGROUND Adaptive working memory training is being implemented without an adequate understanding of developmental trajectories of working memory. We aimed to quantify from Grade 1 to Grade 3 of primary school (1) changes in verbal and visuospatial working memory and (2) whether low verbal and visuospatial working memory in Grade 1 predicts low working memory in Grade 3. METHOD The study design includes a population-based longitudinal study of 1,802 children (66% uptake from all 2,747 Grade 1 students) at 44 randomly selected primary schools in Melbourne, Australia. Backwards Digit Recall (verbal working memory) and Mister X (visuospatial working memory) screening measures from the Automated Working Memory Assessment (M = 100; SD = 15) were used to assess Grades 1 and 3 (ages 6-7 and 8-9 years) students. Low working memory was defined as ≥1 standard deviation below the standard score mean. Descriptive statistics addressed Aim 1, and predictive parameters addressed Aim 2. RESULTS One thousand seventy (59%) of 1802 Grade 1 participants were reassessed in Grade 3. As expected for typically developing children, group mean standard scores were similar in Grades 1 and 3 for verbal, visuospatial, and overall working memory, but group mean raw scores increased markedly. Compared to "not low" children, those classified as having low working memory in Grade 1 showed much larger increases in both standard and raw scores across verbal, visuospatial, and overall working memory. Sensitivity was very low for Grade 1 low working memory predicting Grade 3 low classifications. CONCLUSION Although mean changes in working memory standard scores between Grades 1 and 3 were minimal, we found that individual development varied widely, with marked natural resolution by Grade 3 in children who initially had low working memory. This may render brain-training interventions ineffective in the early school year ages, particularly if (as population-based programmes usually mandate) selection occurs within a screening paradigm.

Abstract
Congenital gingival granular cell tumours are rare lesions which have only occasionally been reported in the UK. Clinical features are of a benign lesion which occurs almost exclusively in newborn, Caucasian females and the anterior maxilla is the commonest site. Treatment consists of local excision and is curative. The terminology concerning this condition has been rather confused because of uncertainty regarding the histogenesis of these tumours and the similar histological appearance to adults granular cell myoblastoma occurring at other intraoral sites. The exact histogenesis of these tumours remains unresolved and they may be hamartomata. We describe a new case occurring within the UK, which illustrates many of the common clinical features of the condition, with an accompanying literature review.

Abstract
Neurodevelopmental delays are known to occur in children with metopic synostosis, but it is presently unclear whether the cognitive, behavioral and psychological outcomes of children with metopic synostosis differ to those of their healthy peers. This meta-analysis consolidated data from 17 studies (published prior to August 2017) that examined the cognitive, behavioral and psychological outcomes of children (n = 666; aged ≤19 yrs) with metopic synostosis. Hedges'g (gw) effect sizes compared the outcomes of samples with metopic synostosis (unoperated, operated) to healthy controls or normative data and, where available, the prevalence of problems/disorders was calculated. Children with unoperated metopic synostosis performed significantly worse than their healthy peers on measures of: general cognition (gw = -.38), motor functioning, (gw = -.81), and verbal (gw = -.82) and visuospatial (gw = -.92) abilities. Children with operated metopic synostosis performed significantly worse on measures of motor functioning (gw = -.45), visuospatial skills (gw = -.32), attention (gw = -.50), executive functioning (gw = -.36), arithmetic ability (gw = -.37), and behavior (gw = -.34). Cognitive, behavioral, and psychological problems were prevalent, but variable. Overall, the cognitive, behavioral, and psychological outcomes of children with metopic synostosis are generally worse than their healthy peers, regardless of surgical status. However, research is sparse, samples small, controls are rarely recruited, and the severity of metopic synostosis often not stated. Nevertheless, the findings suggest that children with metopic synostosis are likely to experience a variety of negative outcomes and should therefore receive ongoing monitoring and support.

Abstract
OBJECTIVES Glypican 1 (GPC1) and glypican 3 (GPC3) are bone co-regulators that act downstream in many of the signalling pathways associated with craniosynostosis. Morphometric data from GPC-knockout mice were analysed to determine whether elimination of GPC1 and GPC3 genes would alter mandibular morphology. SETTING AND SAMPLE POPULATION The murine model included five male and five female mandibles in each of GPC1-knockout, GPC1/GPC3-knockout and wild-type (control) groups. Female GPC3-knockout mice had a very high rate of perinatal lethality, and therefore, only five males were included in this group. METHODS The mandibular morphology of GPC1-knockout (n=10), GPC3-knockout (n=5), GPC1/GPC3-knockout (n=10) and wild-type (n=10) mice was compared by analysing five landmark-based linear dimensions: anterior and posterior lengths, as well as ascending, descending and posterior heights. Measurements were recorded on three-dimensional micro-CT reconstructions. RESULTS GPC3-knockout mandibles were larger than wild-type mandibles for all dimensions (P<.05). Mandibular heights were more affected than lengths. A decreasing trend of mandibular dimensions across the mouse groups (GPC3-knockout>GPC1/GPC3-knockout>GPC1-knockout=wild-type) (P<.05) indicated that an increase in mandibular size was associated with increased GPC3 expression, but not GPC1. CONCLUSIONS Alterations in GPC3 expression are likely to mediate changes to mandibular size in craniosynostosis. These findings have potential future applications in the prevention and treatment of craniosynostosis and associated craniofacial dysmorphology.

Abstract
BACKGROUND Sleep disordered breathing may be a risk factor for high altitude illness. Past Antarctic sleep studies suggest that rapid transport from sea level (SL) to the Amundsen Scott South Pole Station (SP, 2835 m) increases risk of Acute Mountain Sickness (AMS). We analyzed sleep studies in 38 healthy polar workers to explore the association between sleep disordered breathing and AMS after rapid transport to the South Pole. METHODS Subjects completed a baseline questionnaire, performed basic physiology tests, and were evaluated for AMS and medication use using an extended Lake Louise Questionnaire (LLQ) during their first week at the South Pole. Participants were included in this study if they took no medications and underwent polysomnography on their first nights at Sea Level and the South Pole using the Vivometrics LifeShirt(®). Within group changes were assessed with Wilcoxon signed rank tests and between group differences were assessed with Kruskal-Wallis rank sum tests. RESULTS Overall, 21/38 subjects met criteria for AMS at some time on or prior to the third morning at the South Pole. Subjective poor sleep quality was reported by both AMS (65%) and no AMS (41%) groups. The Apnea Hypopnea Index (AHI) increased significantly in both the AMS and no AMS groups, but the difference in the increase between the two groups was not statistically significant. Increased AHI was not associated with increased AMS symptoms. Previous altitude illness (p=0.06) and residence at low altitudes (p = 0.02) were risk factors for AMS. CONCLUSION AMS was not significantly associated with sleep architecture changes or increased AHI. However, AHI sharply increased at South Pole (19/38 participants) primarily due to central apneas. Those developing AMS were more likely to have experienced previous problems at altitude and reported living at lowland altitudes within the 3 months prior to rapid transport to the South Pole than those without AMS.

Abstract
BACKGROUND Preterm birth confers risk for poor outcome, including mental health problems. Survival of extremely preterm (EP; <28 weeks' gestation) or extremely low birthweight (ELBW; <1000 g) infants increased in the 1990s but psychiatric outcomes in older adolescents born preterm since 1990 are not well documented. This study aimed to characterize mental health and personality traits in a prospective geographical cohort of adolescents born EP/ELBW in Victoria, Australia in 1991 and 1992. METHOD At age 18 years, 215 EP/ELBW and 157 normal birthweight (>2499 g) control adolescents completed the Structured Clinical Interview for DSM-IV Disorders, Axis 1 Non-Patient version (SCID-I/NP), the Children's Interview for Psychiatric Syndromes (ChIPS) attention deficit hyperactivity disorder (ADHD) module, and questionnaires assessing recent depression and anxiety symptoms and personality traits. RESULTS ADHD prevalence was significantly elevated in EP/ELBW adolescents compared with controls [15% v. 7%; odds ratio (OR) 2.67, 95% confidence interval (CI) 1.08-6.58]. Aside from ADHD, however, EP/ELBW and control adolescents reported very similar outcomes, with other lifetime diagnoses identified in 23% of EP/ELBW and 21% of controls. These were predominantly mood and anxiety disorders (21% EP/ELBW, 20% controls). The groups did not differ in recent depression or anxiety symptoms assessed using questionnaires, and personality traits were also similar. CONCLUSIONS ADHD was more prevalent in EP/ELBW adolescents than controls, which is consistent with some, but not all, reports on preterm survivors born before the 1990s, and younger preterm children born in the 1990s. The high rates of anxiety and mood disorders were similar in both groups, and comparable with population-based estimates.

Abstract
BACKGROUND & AIMS Adequate protein intake and digestion are necessary to prevent muscle wasting in cystic fibrosis (CF). Accurate and easy-to-use methodology to quantify protein maldigestion is lacking in CF. OBJECTIVE To measure protein digestibility and the response to pancreatic enzyme intake in CF by using a new stable isotope methodology. DESIGN In 19 CF and 8 healthy subjects, protein digestibility was quantified during continuous (sip) feeding for 6 h by adding (15)N-labeled spirulina protein and L-[ring-(2)H5]phenylalanine (PHE) to the nutrition and measuring plasma ratio [(15)N]PHE to [(2)H5]PHE. Pancreatic enzymes were ingested after 2 h in CF and the response in protein digestibility was assessed. To exclude difference in mucosal function, postabsorptive whole-body citrulline (CIT) production rate was measured by L-[5-(13)C-5,5-(2)H2]-CIT pulse and blood samples were taken to analyze tracer-tracee ratios. RESULTS Protein digestibility was severely reduced in the CF group (47% of healthy subjects; P < 0.001). Intake of pancreatic enzymes induced a slow increase in protein digestibility in CF until 90% of values obtained by healthy subjects. Maximal digestibility was reached at 100 min and maintained for 80 min. Stratification into CF children (n = 10) and adults showed comparable values for protein digestibility and similar kinetic responses to pancreatic enzyme intake. Whole-body citrulline production was elevated in CF indicating preserved mucosal function. CONCLUSION Protein digestibility is severely compromised in patients with CF as measured by this novel and easy-to-use stable isotope approach. Pancreatic enzymes are able to normalize protein digestibility in CF, albeit with a severe delay. Registration ClinicalTrials.gov = NCT01494909.

Abstract
Craniosynostosis is one of the most common craniofacial disorders encountered in clinical genetics practice, with an overall incidence of 1 in 2,500. Between 30% and 70% of syndromic craniosynostoses are caused by mutations in hotspots in the fibroblast growth factor receptor (FGFR) genes or in the TWIST1 gene with the difference in detection rates likely to be related to different study populations within craniofacial centers. Here we present results from molecular testing of an Australia and New Zealand cohort of 630 individuals with a diagnosis of craniosynostosis. Data were obtained by Sanger sequencing of FGFR1, FGFR2, and FGFR3 hotspot exons and the TWIST1 gene, as well as copy number detection of TWIST1. Of the 630 probands, there were 231 who had one of 80 distinct mutations (36%). Among the 80 mutations, 17 novel sequence variants were detected in three of the four genes screened. In addition to the proband cohort there were 96 individuals who underwent predictive or prenatal testing as part of family studies. Dysmorphic features consistent with the known FGFR1-3/TWIST1-associated syndromes were predictive for mutation detection. We also show a statistically significant association between splice site mutations in FGFR2 and a clinical diagnosis of Pfeiffer syndrome, more severe clinical phenotypes associated with FGFR2 exon 10 versus exon 8 mutations, and more frequent surgical procedures in the presence of a pathogenic mutation. Targeting gene hot spot areas for mutation analysis is a useful strategy to maximize the success of molecular diagnosis for individuals with craniosynostosis.

Abstract
INTRODUCTION This paper reviewed the outcome of cantilevered costochondral grafts used for dorsal nasal augmentation in the management of patients treated at the Australian Craniofacial Unit (ACFU), Adelaide over a 29-year period. MATERIALS AND METHODS All patients undergoing dorsal nasal augmentation with costochondral grafts as part of their craniofacial management between 1981 and 2009 were identified using the ACFU database, and their medical notes were reviewed. RESULTS 107 patients (50 M, 57 F), with a mean age of 12.3 years (range: 2-62 years) and requiring a total of 150 costochondral grafts, were identified from the departmental database. Mean follow-up after nasal augmentation was 5.6 years (1 month-31.5 years). 46% of the patients were diagnosed with Binder syndrome/Chondrodysplasia punctata; other diagnoses included Tessier midline clefts, cleft lip and palate and frontonasal dysplasia. A dorsal midline incision (49%) was the commonest method of access, with 84% of patients having mini-screw fixation for graft stabilisation. Complications included screw palpability, infection, skin necrosis and graft fracture. The commonest reasons for a replacement graft were graft atrophy and fracture, infection and persistent deformity. CONCLUSION Cantilevered nasal costochondral grafting is an excellent technique for improving nasal contour and function in a wide variety of clinical situations.

Abstract
The purpose of this study was to determine risk and protective factors for adult psychiatric disorders in very low birth weight (VLBW, birth weight <1,501 g) survivors. 79 of 154 (51%) VLBW subjects recruited at birth were assessed in early adulthood (24-27 years). Participants were screened for a psychiatric disorder; those elevated were invited to attend a structured clinical interview to determine a clinical diagnosis. Longitudinal variables measured from birth and at ages 2, 5, 14 and 18 years were included in analyses. Perinatal, developmental and social environmental risk factors failed to predict psychiatric disorder in adulthood in this cohort of VLBW survivors. Instead, low self-esteem at age 18 (odds ratio [OR] = 1.05, 95% confidence interval [CI] = 1, 1.11, p = 0.05) and the adult social environment (high rates of negative life event stress at the time of assessment: OR = 1.39, CI = 1.10, 1.76, p = 0.02), contributed significantly to adult psychiatric outcomes.

Abstract
BACKGROUND Preterm (PT) birth and low birth weight (LBW) are high-prevalence events that are associated with adverse outcomes in the longer term, with vulnerability increasing as maturity at birth decreases. Psychiatric symptomatology appears heightened in PT/LBW survivors, though there are some discordant findings from studies using questionnaire measures, particularly with respect to anxiety and depressive symptoms. METHOD This article synthesises findings from research using clinical psychiatric diagnostic criteria in PT/LBW individuals aged 10-25 years compared with term-born peers. Key outcomes of interest were the rates of individuals receiving any psychiatric diagnosis and the number of diagnoses of anxiety or depressive disorders. RESULTS A literature search for studies reporting prevalence of 'any diagnosis' yielded five studies that met inclusion criteria, with a total of 565 PT/LBW and 533 control individuals. Also, five studies were found that reported rates of anxiety/depression (692 PT/LBW and 605 control individuals). The risk of these outcomes was increased for PT/LBW individuals compared with controls [any diagnosis: odds ratio (OR) 3.66, 95% confidence interval (CI) 2.57-5.21; anxiety or depressive disorder: OR 2.86, 95% CI 1.73-4.73]. CONCLUSIONS The studies reviewed here indicate that, in addition to monitoring and management of medical and cognitive sequelae, the psychological well-being of PT/LBW individuals should be a key part of ongoing care.

Abstract
OBJECTIVE To determine the survival and neurological outcome at 2 years of age of extremely low birthweight (ELBW, birth weight 500-999 g) infants born in the state of Victoria compared with term controls, and contrasted with ELBW cohorts from previous eras. DESIGN AND SETTING A population-based cohort study of consecutive ELBW infants born during 2005 in the state of Victoria, and also in 1979-1980, 1985-1987, 1991-1992 and 1997. PARTICIPANTS All 257 live births free of lethal malformations weighing 500-999 g in 2005, 220 randomly selected term, normal birthweight (birth weight >2499 g) controls, and equivalent cohorts born in earlier eras. MAIN OUTCOME MEASURES Survival rates and quality-adjusted survival rates at 2 years of age, contrasted between cohorts. RESULTS Of 257 ELBW live births in 2005, 66.9% survived to 2 years of age, significantly lower than the survival rate of 75.2% for 1997 (odds ratio (OR) 0.67, 95% CI 0.45 to 0.99, p=0.046), but not after adjustment for confounders of birth weight, gestational age and gender (adjusted OR 0.73, 95% CI 0.46 to 1.16, p=0.18). This was a reversal of the steady increase in survival rates up to 1997. Rates of blindness, severe developmental delay and severe disability were significantly lower in 2005 than in ELBW survivors from previous eras. Consequently the difference in the quality-adjusted survival rates between 2005 and 1997 was only -3.8% (95% CI -11.4% to 3.7%, p=0.32). CONCLUSIONS Regional survival rates for ELBW infants have plateaued since the late 1990s, but the neurosensory outcome in survivors has improved in 2005.

Abstract
BACKGROUND AND PURPOSE DEHSI on T2-weighted MR imaging in preterm infants at term-equivalent age has been regarded as an unfavorable marker for neurodevelopmental outcome. The aim of this study was to examine the relationship between the presence and extent of DEHSI and neurodevelopmental outcomes. MATERIALS AND METHODS We evaluated the MR images of 160 preterm infants at term-equivalent age. The presence of DEHSI was evaluated in separate regions and classified into 5 grades based on the extent of DEHSI. We also examined within those infants with DEHSI, whether typical signal-intensity characteristics of the posterior periventricular crossroads region were visible. Finally, ADC and FA values within the white matter were analyzed. Neurodevelopmental outcomes were assessed at 2-year corrected age with a standardized neurologic examination and the BSID-II. RESULTS The grade of DEHSI had significant linear trends with increasing ADC and a trend toward lower FA values. However, there was no relationship between the degree of DEHSI and 2-year neurodevelopmental outcomes. In contrast, 13 infants with DEHSI who did not have visible posterior crossroads had poorer neurodevelopmental outcomes compared with infants with visible posterior crossroads. CONCLUSIONS Although DEHSI may represent disturbances in white matter structure, as illustrated by its relationship to altered ADC and FA values, there is no relationship to short-term neurodevelopment outcome unless there are invisible posterior crossroads, representing a severe form of global high T2 signal intensity.

Abstract
OBJECTIVE Studies reporting the developmental outcomes for very preterm (VPT) children often focus on development at age 2 years. The aim of this study was to assess the stability of the rates of diagnosis of developmental disability from age 2 to 8 years in a regional cohort of VPT and extremely low-birth weight (ELBW) children and compare these with term controls. METHODS VPT (22-27 completed weeks of gestation) and ELBW (birth weight 500-999 g) children and matched term controls born in Victoria, Australia, in 1997 were enrolled at birth in a regional prospective longitudinal study. Outcomes were assessed at ages 2 and 8 years. RESULTS Of the 283 VPT/ELBW live births, 71% survived to age 8 years and 94% were assessed. Of the 199 controls, 100% survived to age 8 years and 86.9% were assessed. At age 2 years, the rates of nil, mild, moderate and severe disabilities in the VPT/ELBW children were respectively 51.9%, 20.9%, 13.4% and 13.9%; and at age 8 years, 43.9%, 36.9%, 10.7% and 8.6%. The Cohen κ statistic revealed poor agreement between disability status at ages 2 and 8 years for VPT/ELBW children (0.20, p<0.001) but a higher level of agreement (0.37, p<0.001) for the control children. This was primarily driven by differences in classification of cognitive disability between ages 2 and 8 years. CONCLUSIONS Developmental outcomes at age 2 years are only a moderate predictor of long-term outcome and are not a reliable end point for follow-up studies of VPT and ELBW children.

Abstract
BACKGROUND Van der Woude syndrome (VWS) is the most common clefting syndrome in humans. It is characterized by the association of congenital lower lip fistulae with cleft lip and/or cleft palate. VWS individuals have a high prevalence of hypodontia. Although caused by a single gene mutation, VWS has variable phenotypic expression. This study aimed to describe the range of clinical presentations in 22 individuals with VWS to facilitate its diagnosis. METHODS A retrospective study of 22 patients with a diagnosis of VWS was undertaken at the Australian Craniofacial Unit (ACFU) in Adelaide. Three extended families with affected members were included in the study cohort. RESULTS The overall prevalence of lip pits in this study cohort was 86%. Cleft phenotypes included bilateral cleft lip and palate (32%); unilateral cleft lip and palate (32%); submucous cleft palate (23%); and isolated cleft hard and soft palate (9%). Missing permanent teeth were reported in 86% of affected individuals. CONCLUSIONS Submucous cleft palate in VWS may go undiagnosed if the lower lip pits are not detected. Associated hypodontia and resultant malocclusions will also require management by a dental team.

Abstract
BACKGROUND The survival rate for children born with gestational ages 22-27 weeks is increasing, and this may be associated with higher rates of disability. The aims of this study were to determine the outcomes at age eight for a regional cohort of children born at 22-27 weeks during 1997, and to compare their rates of disability with a cohort of the same gestational age born in 1991-1992. METHODS Consecutive children with gestational ages in the range 22-27 weeks born in the state of Victoria, Australia, in 1997 and matched term controls were assessed at 8 years. Outcomes included blindness, deafness, cerebral palsy (CP) and intellectual impairment and disabilities caused by these impairments. These outcomes were compared with a cohort of 22-27-week and term children born in 1991-1992 in the same region. RESULTS Follow-up rates for the 1997 cohort at 8 years of age were 95% (144/151) for 22-27 weeks survivors and 89% (173/195) for controls. Rates of disability were substantially higher in the preterm cohort than the controls. The 1997 and 1991-1992 preterm cohorts had similar rates of moderate or severe disability (19%), however the rate of mild impairment was greater in 1997 (40% vs 24%). Rates of disability were almost identical in control groups. Intellectual impairment and CP were the major reasons for the higher rates of disability. CONCLUSIONS The high prevalence of adverse neurodevelopmental outcome in children born at 22-27 weeks compared with term controls at school age persists, and may even be increasing over time.

Abstract
BACKGROUND ADAMTS-13 proteolytic activity is controlled by the conformation of its substrate, von Willebrand factor (VWF), and changes in the secondary structure of VWF are essential for efficient cleavage. Substrate recognition is mediated through several non-catalytic domains in ADAMTS-13 distant from the active site. OBJECTIVES We hypothesized that not all binding sites for ADAMTS-13 in VWF are cryptic and analyzed binding of native VWF to ADAMTS-13. METHODS Immunoprecipiation of VWF-ADAMTS-13 complexes using anti-VWF antibodies and magnetic beads was used. Binding was assessed by Western blotting and immunosorbent assays. RESULTS Co-immunoprecipitation demonstrated that ADAMTS-13 binds to native multimeric VWF (K(d) of 79 +/- 11 nmol L(-1)) with no measurable proteolysis. Upon shear-induced unfolding of VWF, binding increased 3-fold and VWF was cleaved. Binding to native VWF was saturable, time dependent, reversible and did not vary with ionic strength (I of 50-200). Moreover, results with ADAMTS-13 deletion mutants indicated that binding to native VWF is mediated through domains distal to the ADAMTS-13 spacer, probably thrombospondin-1 repeats. Interestingly, this interaction occurs in normal human plasma with an ADAMTS-13 to VWF stoichiometry of 0.0040 +/- 0.0004 (mean +/- SEM, n = 10). CONCLUSIONS ADAMTS-13 binds to circulating VWF and may therefore be incorporated into a platelet-rich thrombus, where it can immediately cleave VWF that is unfolded by fluid shear stress.

Abstract
BACKGROUND AND PURPOSE White matter signal-intensity abnormalities (WMSA) on MR imaging are related to adverse neurodevelopmental outcome in extremely preterm infants. Diffusion tensor imaging (DTI) may detect alterations in cerebral white matter microstructure and thus may help confirm the pathologic basis of WMSA. This study aimed to relate regional DTI measures with severity of WMSA in very preterm infants. MATERIALS AND METHODS One hundred eleven preterm infants (birth weight, <1250 g and/or gestational age, <30 weeks) were scanned at term-equivalent age (1.5T). WMSA were classified as normal, focal, or extensive. Apparent diffusion coefficient (ADC), fractional anisotropy (FA), axial (lambda1), and radial ([lambda2 + lambda3]/2) diffusivity were calculated in 12 regions of interest placed in the bilateral posterior limbs of the internal capsule, frontal (superior and inferior), sensorimotor, and occipital (superior and inferior) white matter regions. Data were compared by using 1-way analysis of variance, with a Bonferroni correction for multiple comparisons. RESULTS Thirty-nine infants had normal, 59 infants had focal, and 13 infants had extensive WMSA. Compared with infants with normal or focal WMSA, infants with extensive WMSA had significantly lower FA in the internal capsule (P < .001), right inferior frontal regions (P < .05), and right superior occipital regions (P = .01); and higher radial diffusivity in the right internal capsule (P = .005), bilateral sensorimotor (P < .05), and right superior occipital regions (P < .05). Compared with infants with normal WMSA, infants with extensive WMSA had significantly higher ADC in bilateral sensorimotor regions (P < .01) and right superior occipital regions (P = .01), and lower axial diffusivity in the bilateral sensorimotor regions (P < .05). CONCLUSIONS There are significant region-specific changes in ADC, FA, radial diffusivity, and axial diffusivity in preterm infants with extensive WMSA. Altered radial diffusivity was most prominent. This implies that disrupted premyelinating oligodendroglia is the major correlate with extensive WMSA rather than axonal pathology.

Abstract
BACKGROUND AND PURPOSE The application of volumetric techniques to preterm infants has revealed brain volume reductions. Such quantitative data are not available in routine neonatal radiologic care. The objective of this study was to develop simple brain metrics to compare brain size in preterm and term infants and to correlate these metrics with brain volumes from volumetric MR imaging techniques. MATERIALS AND METHODS MR images from 189 preterm infants <30 weeks' gestational age or <1250 g birthweight scanned at term-equivalent age and 36 term infants were studied. Fifteen tissue and fluid measures were systematically evaluated on 4 selected sections. The results were correlated with total brain, gray matter, white matter, and CSF volumes. RESULTS The mean bifrontal, biparietal, and transverse cerebellar diameters were reduced (-11.6%, 95% confidence interval [CI], -13.8% to -9.3%; -12%, 95% CI, -14% to -9.8%; and -8.7%, 95% CI, -10.5% to -7% respectively) and the mean left ventricle diameter was increased (+22.3%, 95% CI, 2.9%-41.6%) in preterm infants (P < .01). Strong correlations were found between the bifrontal and biparietal measures with total brain tissue volume, whereas the size of the ventricles and the interhemispheric measure correlated with CSF volume. Intraobserver reliability was high (intraclass correlation coefficients [ICC], >0.7), where interobserver agreement was acceptable for tissue measures (ICC, >0.6) but lower for fluid measures (ICC, <0.4). CONCLUSIONS Simple brain metrics at term-equivalent age showed smaller brain diameters and increased ventricle size in preterm infants compared with full-term infants. These measures represent a reliable and easily applicable method to quantify brain growth and assess brain atrophy in this at-risk population.

Abstract
The aims of this study were to determine the motor outcome of extremely-low-birthweight (ELBW; <1000g) or very preterm (<28wks) children compared with normal birthweight (NBW) children, to establish the perinatal associations of developmental coordination disorder (DCD) and its cognitive and behavioural consequences. Participants were consecutive surviving ELBW or very preterm children and randomly selected NBW(>2499g) children born in the state of Victoria, Australia, in 1991 or 1992. Main outcomes were: (1) results of the Movement Assessment Battery for Children (MABC) at 8 years of age; (2) cognitive function; (3) academic progress; and (4) behaviour. Of 298 consecutive ELBW/very preterm survivors, 255 (85.6%; 117 males, 138 females) had the MABC at a mean age of 8 years 8 months. More ELBW/very preterm children (9.5%) had DCD than the NBW group (2%, p=0.001). Only male sex increased the likelihood of DCD in ELBW/very preterm children (p=0.017). ELBW/very preterm children with DCD had worse cognitive function and academic test scores (up to 1SD below those without DCD); they also had more adaptive behaviour and externalizing problems, but not internalizing problems. DCD is more common in ELBW/very preterm children, has few perinatal correlates, and is associated with poor cognitive and academic performance as well as increased behaviour problems.

Abstract
BACKGROUND With little in the published literature on the conservative management of facial fractures we set out to determine whether our current criteria for treatment are valid. METHOD Two hundred and thirty adult patients with fractures of the facial skeleton were treated conservatively by our unit between February 1997 and January 2003. Their notes were reviewed retrospectively. RESULTS Most patients were males (76%), the average age was 38 years, and drugs or alcohol were a significant aspect of the history in 30% of the cases. The most common mechanism of injury was assault (47%), followed by falls and sporting injuries. Fifty percent of the fractures involved the orbital or orbito-zygomatic complex, and 55% had associated injuries. Average follow-up was for six weeks (range 0-44 weeks). Most patients were managed conservatively based on our current criteria of un-displaced/minimally displaced fracture (57%); or minimal/no symptoms (24%). At final review, a number had residual symptoms, but only three required corrective surgery. The other reasons for conservative management included patient non-compliance (11%), and medical contraindications (8%). CONCLUSION Our results support current indications for the conservative management of facial fractures, but emphasise the need for ongoing follow-up of these patients.

Abstract
10551 Background: External Beam Radiation Therapy (EBRT) has been the standard of care for breast conservation radiation therapy. Recent data indicates that Interstitial Implant and High Dose Rate (HDR) radiation afterloading compares favorably to EBRT in selected patients. Methods: Patients with Tis, T1, and T2 tumors measuring ≤ 3 cm, negative surgical margins, and negative axillary lymph nodes were judged to be candidates for Interstitial Implant. Results: Between 2000 and 2006, 112 patients underwent Interstitial HDR Implant under Stereotactic Mammographic guidance with conscious sedation and local anesthesia. Conscious sedation consisted of Morphine and Versed. Local anesthesia was given with a mixture of 1% Lidocaine, 0.25% Marcaine, 1:100,000 Epinephrine, and 4% Sodium Bicarbonate neutralizing solution. The implants were placed using a Template with from 3 to 6 planes, and 8 to 43 needles. Catheters were subsequently threaded thru the needles, and the needles removed. Catheter spacing was 1.0 to 1.5 cm. Radiation Treatment planning was performed using CT Scanning. Treatment volumes ranged from 25 cm3 to 359 cm3. The breast implant volume received 3400 cGy in 10 fractions via HDR prescribed to the Planning Target Volume, given BID over 5 days. The procedure was well tolerated. No patient required hospital admission. With a median follow-up 36 months (range 6–60 months), local recurrence occurred in 2.7% (3/112). Cosmetic results were good to excellent in 85.7% (96/112) of the patients. Wound healing complications developed in 7.1% (8/112). Three of these patients had received anthracycline based Chemotherapy. The other five had large (> 200 cm3) implant volumes and catheter spacing of 1.5 cm. Two patients healed after 6 months of conservative treatment. Surgery was required in six patients who developed fat necrosis. Conclusions: With median 36 month follow-up, Breast Conservation radiation therapy utilizing Interstitial HDR Implant has yielded local recurrence rates and cosmetic results which compare favorably to EBRT in selected patients. Treatment with anthracycline based Chemotherapy and large (> 200 cm3) implant volumes appear to be relative contraindications to Interstitial HDR Implant. Finally, catheter spacing of 1 cm yielded optimal dosimetry and minimized complications. No significant financial relationships to disclose.

Abstract
14633 Background: Transrectal Ultrasound (TRUS) guided interstitial implant for prostate cancer using Low Dose Rate (LDR) and High Dose Rate (HDR) technique has been reported with results comparing favorably to surgery and External Beam Radiation Therapy (EBRT). Often, HDR and LDR interstitial implant is combined with EBRT. There is little published data on HDR alone. We report our results with HDR alone. Methods: Between 1997 and 2006, 167 patients with T1 and T2 localized prostate underwent TRUS guided interstitial implant. There were no Gleason Score or PSA exclusions. No patient received EBRT or Hormonal Blockade. Median Gleason Score was 7 (range: 4 to 10). Median PSA was 9.3 (2.7 to 39.8). Treatment volumes ranged from 42 cm3 to 196 cm3. Treatment volume included the prostate and seminal vesicles in all cases. Our protocol for HDR alone, has called for two HDR Implants. The treatment volume received 2,250 cGy in 3 fractions prescribed to the 100% Isodose line, given over 24 hours. A 2nd implant was performed 4 weeks later, delivering a further 2,250 cGy in 3 fractions, bringing the final dose to the prostate to 4,500 cGy in 6 fractions. Urethral dose points (12–16) were followed, and limited to ≤ 105% of the prescription dose. Results: With a median follow-up of 64 months (range: 6 months to 112 months), PSA disease free survival was 89.8% (150/167). Urethral stricture requiring dilatation has developed in 4.2% (7/167) of patients. Urinary stress incontinence has occurred in 3.6% (6/167). RTOG late bladder toxicities were: 0% Grade 4, 0% Grade 3, and 3.6% (6/167) Grade 2. RTOG late rectal toxicities were: 0.6% (1/167) Grade 4, 0% Grade 3, 1.8% (3/167) Grade 2, and 2.4% (4/167) Grade 1. There have been no cases of rectal incontinence to date. Conclusions: Five year results with HDR implant alone compare favorably to EBRT, LDR ± EBRT, and HDR + EBRT, both with regard to PSA disease free survival, and complications. HDR offers other advantages over LDR, such as no radiation exposure to hospital personnel, no seed migration, greater dose flexibility and precision of radiation dose delivery. Larger volumes can be treated with HDR. By omitting EBRT, bladder and rectal complications appear to be significantly reduced. No significant financial relationships to disclose.

Abstract
18603 Background: Stereotactic Radiosurgery (SRS) with the Gamma Knife (GK) has been used successfully in the treatment of Trigeminal Neuralgia (TN). Results have been comparable to open surgery. There have been few reports with the use of LSRS in the management of TN. We report our updated results with LSRS in the treatment of TN. Methods: Between 2000 and 2006, 37 patients with medically refractory TN were treated with LSRS. Prior neurosurgical intervention had been performed in 28 patients. Ten patients had one procedure, 10 patients two, and 3 patients three interventions. All patients had typical TN. LSRS was given to the cranial nerve V entry root zone into the brainstem. Targeting was defined by CT and MRI Scans, and CT Cisternogram, utilizing axial, coronal, and sagittal images. Treatment planning was accomplished thru the Radionics Treatment Planning System. The dose was 87 Gy to Dm, in one fraction using the 5 mm collimator and 6 arcs with the 20% Isodose line just touching the brainstem. This dosimetry is similar to Gamma Knife. The dose rate was 400 MU/min. Average Arc length was 130 degrees. Response to treatment was defined as excellent (no pain, off analgesics), good (no pain, with analgesics), and poor (continued pain despite analgesics). Results: With a median follow-up of 40 months (range 6–72 months), 73% (27/37) of patients have reported an excellent or good result after LSRS. One patient has sustained permanent ipsilateral facial numbness. Conclusions: LSRS offers comparable results to Gamma Knife SRS, with respect to both pain relief and complications, in the management of TN. No significant financial relationships to disclose.

Abstract
12513 Background: Radioimmunotherapy using radioactive Iodine -131 labeled radioimmuno conjugate called Tositumomab has been used in the treatment of non-Hodgkin’s lymphoma. Radiation dosimetry and safety aspects of this treatment modality are very critical for successful implementation of this treatment. Methods: Since year 2001, we have treated 17 patients using I-131-tositumomab. There were 11 female and 6 male patients at age range of 40 to 82 years. Patient specific dosimetry was performed on all the patents using a tracer dose of I-131. The whole body counts were performed after infusion of 5.0 mCi of I-131-tositumomab and whole body counts were taken at 0, 48 and 178 hours. The total body residence time (TBRT) for 37% of the activity to stay in the body was determined by graphical method. The activity in mCi, for delivering 65 cGy or 75 cGy whole body dose, was calculated based on the TBRT and patient’s weight. Based on the measured exposure rate, we have calculated the total effective dose equivalent (TEDE) to the public. The patients were released to home with radiation safety instructions if TEDE delivered to the public was less than 5.0 mGy. We have studied the platelet count recovery time for all the patients, following treatment. Results: The calculated TBRT ranged from 85 to 175 hours and the the mCi/Kgm varied from 1.4 to 0.6, related inverse proportion with TBRT. For both group of patients, treated with total body dose of 65 cGy and 75 cGy, the mCi/Kgm was the same, for TBRT values exceeding 100 hours. The TEDE to public varied from 1.02 to 3.22 mGy, while the exposure rate measured on the patient at 1 meter was less than the permissible value reported in the literature for safe release. Conclusion: The above results show that the patients can be treated as outpatient using I-131 -tositumomab with radiation safety restrictions lasted for one week. The radiation exposure to the public was less than the maximum permissible dose equivalent. No significant financial relationships to disclose.

Abstract
14606 Background: Transrectal Ultrasound (TRUS) guided interstitial implant for prostate cancer using High Dose Rate (HDR) + External Beam Radiation Therapy (EBRT) or IMRT has been reported with favorable results. The role of supplemental EBRT or IMRT in brachytherapy is undefined. We compare our results of HDR + IMRT vs. HDR monotherapy. Methods: Between 1997 and 2006, 276 patients with T1 and T2 localized prostate underwent TRUS interstitial implant. After discussion of treatment options, 109 patients elected HDR Implant + IMRT and 167 patients underwent HDR alone. No patient received Hormonal Blockade. Median Gleason Score was 7 (range: 4 to 10). Median PSA was 9.8 (0.60 to 39.8). In patients who received IMRT + HDR, 4500 cGy in 25 fractions was given via IMRT and 1650 cGy in 3 fractions via HDR. Our protocol for HDR alone, has called for two HDR Implants. The treatment volume received 2,250 cGy in 3 fractions prescribed to the 100% Isodose line, given over 24 hours. A 2nd implant was performed 4 weeks later, delivering a further 2,250 cGy in 3 fractions, bringing the final dose to the prostate to 4,500 cGy in 6 fractions. Results: There was no significant difference between the treatment groups with respect to T-Stage, Gleason Score, and PSA. With a median follow-up of 66 months (range: 6 months to 120 months), the overall PSA disease free survival (DFS) was 89.5% (247/276). In patients undergoing IMRT + HDR, PSA DFS was 89.0% (97/109) vs. 89.8% (150/167) for patients undergoing HDR alone (p = 0.6). The 5 year actuarial survival was 86% for the group receiving IMRT + HDR vs. 89% with HDR (log rank = 0.5). Urinary stress incontinence has occurred in 2.5% (7/276). RTOG late bladder toxicities were: 0% Grade 4, 0% Grade 3, and 3.3% (9/276) Grade 2. RTOG late rectal toxicities were: 0.4% (1/276) Grade 4, 0% Grade 3, 3.6% (10/276) Grade 2, and 4.7% (13/276) Grade 1. RTOG late rectal toxicity was higher in patients undergoing HDR + IMRT with 14.7% (16/109) of patients experiencing Grade 2 and 1 symptoms, vs. 3.0% (5/167) receiving HDR alone (p ≤ 0.01). Conclusions: We have observed no difference in PSA DFS in patients undergoing HDR vs. HDR + IMRT. Complications were similar, though RTOG Grade 1 and 2 late toxicity was higher in patients receiving HDR + IMRT. By omitting IMRT, rectal complications may be reduced. No significant financial relationships to disclose.

Abstract
14639 Background: Transrectal Ultrasound (TRUS) guided interstitial implant for prostate cancer using Low Dose Rate (LDR) and High Dose Rate (HDR) techniques has been reported with results comparing very favorably to external beam radiation therapy. TRUS interstitial implant of the prostate has been traditionally performed under general or spinal anesthetic in an operating room. We report our results with a technique performed under local anesthesia in a Department procedure room. Methods: Patients with T1 and T2 localized prostate cancer were judged to be candidates for TRUS guided interstitial implant. Results: Between 2002 and 2006, 248 TRUS guided prostate implants were performed under local anesthesia. Conscious sedation consisted of intravenous Morphine (12–22 mg) and Versed (6–14 mg), or intravenous Demerol (50–175 mg) and Versed (3–12 mg). Local anesthetic was given with a mixture of 1% Lidocaine, 0.25% Marcaine, 1:100,000 Epinephrine, and 4% Sodium Bicarbonate neutralizing solution (20–120 cc). Local anesthesia was given to a 5 × 5 cm perineal area to a depth of 10 cm under TRUS guidance. The implants were placed under mobile multi-plane prostate template (Radiation Therapy Products Prostate Template) guidance using from 3 to 4 planes, and 12 to 22 needles. Needle spacing was 1.0 cm. The implant procedure included sigmoidoscopy and cystoscopy. Median implant time was 45 minutes (range: 30 to 150 minutes). HDR treatment was given using the Nucletron afterloading system. The implant volume received 2,250 cGy in 3 fractions prescribed to the 100% Isodose line, given over 24 hours. Urethral dose points (12–16) were followed, and limited to ≤ 105% of the prescription dose. The procedure was well tolerated, with all patients having completed the procedure. One patient developed respiratory suppression, and required reversal with Narcan. He recovered uneventfully. Otherwise, there have been no acute complications to date. Conclusions: TRUS interstitial implant of the prostate under local anesthesia is feasible. Implant time and complications compare favorably to general or spinal anesthetic technique. No significant financial relationships to disclose.

Abstract
OBJECTIVE To investigate facial asymmetry associated with both deformational and synostotic plagiocephaly and to identify variables based on skeletal landmarks that distinguish the conditions and quantify severity. DESIGN Retrospective, cross sectional. SETTING Australian Craniofacial Unit, Adelaide. MAIN OUTCOME MEASURES Proportional differences between bilateral distances and principal component (PC) analysis of the skeletal landmarks. PATIENTS The three-dimensional positions of 78 osseous landmarks were determined from computed tomography (CT) scans of 21 patients with deformational plagiocephaly (DP), 20 patients with unilateral coronal synostosis (UCS), and 2 patients with unilateral lambdoid synostosis (ULS). RESULTS For both DP and UCS, significant asymmetry was found for the orbital depths, mandibular lengths, maxillary depths, zygomatic arch lengths, lateral base of the parietal bone, and the angle between the anterior and the posterior cranial base projected onto the axial plane. The small sample size for ULS precluded definitive statistical statements but allowed some useful comparisons with the other conditions. The first three PC scores were able to distinguish among the three conditions and which side was affected. CONCLUSIONS The asymmetry of the cranial base and facial structures, arising from localized abnormality or deformational forces in either the frontal or the occipital regions, can be quantified by a plethora of bilateral features or summarized by PC analysis.

Abstract
BACKGROUND The authors present an unusual complication of mandibular distraction in a child with the curious condition of multiple pterygium syndrome is presented. CASE REPORT The patient was a Caucasian male with severe pterygia in his neck. As a result of his limited mouth opening and restricted upper airway leading to obstruction, he underwent lengthening of his mandible by distraction, which significantly improved his breathing. During his follow-up, it was observed that an unusually elongated permanent molar was present in an abnormal position. CONCLUSION This case highlights the need to carefully plan the sites for osteotomy and the potential for damage to the developing permanent dentition in young children.
