Abstract
OBJECTIVE To compare differences in demographics and injuries of patients presenting after falls from heights at home and at work. METHOD A retrospective case series review of patients treated by the Royal Adelaide Hospital (RAH) Trauma Service following a fall from a ladder, scaffold, building, or tree between July 2000 and December 2003. RESULTS Two hundred and eighty-two patients fulfilled study criteria. The 162 (57.4%, 95% confidence interval [CI] 48.9-60.5) injured at home were significantly (P < 0.001) older (mean age 53.9 years, 95% CI 51.3-56.7) than those injured at work (mean age 41.2 years, 95% CI 38.6-43.8). Injury severity score (ISS) was similar in the two groups. Those injured at home were more likely to be admitted to hospital and have significantly longer hospital stays (P = 0.003). Thirteen deaths were recorded, eight (61.5%) from home, all over 49 years old. Ladders were implicated in seven (53.8%, 95% CI 26.7-80.9) of the deaths. A 67% (95% CI 55.4-79.0) increase in the number of presentations following falls at home over the study period was significantly greater than the 12.2% (95% CI 10.7-13.7) increase in total trauma presentations during this time (P = 0.0007). CONCLUSIONS Injuries resulting from falls at home are increasing. This group tends to be elderly and at risk of significant injury and prolonged hospital stays. Causes are multifactorial and might be related to increased popularity of home renovations. Ladders are implicated in many of these accidents. As emergency physicians we should target this population to educate them in safe ladder use.

Abstract
AIM To ascertain the prevalence of significant Retinopathy of Prematurity (ROP) and ROP requiring treatment in infants born greater than 30 weeks gestation and with a birthweight greater than 1250 g, utilising the Neonatal Intensive Care Units' (NICUS) data collection from 1998 to 2002. Second, to determine whether infants delivered at more than 30 weeks gestation or with a birthweight greater than 1250 g require ROP screening. METHODS A review of the New South Wales and Australian Capital Territory NICUS data collection from 1998 to 2002 was performed. Infants of gestational age 31-33 weeks and with a birthweight greater than 1250 g were included. A review was performed of these infants to ascertain stage of ROP, threshold disease and treatment for ROP. RESULTS 2292 infants were greater than 30 weeks and had a birthweight greater than 1250 g. Of these 1386 (60%) were not examined or died prior to eye examination. No ROP was noted in 888 of the 904 infants examined (98%), 13 infants had stage 1 (1.4%), five infants stage 2 (0.6%) and no infant had stage 3 ROP. No infant developed stage 3 ROP, required treatment for ROP or had threshold disease. CONCLUSION In this regional study of infants greater than 30 weeks gestation and with a birthweight greater than 1250 g, the prevalence of any ROP was low (2.0%). This study supports evidence from other studies that screening for ROP could be restricted, at least within our referral network, to infants less than 30 completed weeks and a birthweight less than 1250 g.

Abstract
The responses of the gut hormone peptide YY (PYY) to food were investigated in 20 normal-weight and 20 obese humans in response to six test meals of varying calorie content. Human volunteers had a graded rise in plasma PYY (R2 = 0.96; P < 0.001) during increasing calorific meals, but the obese subjects had a lower endogenous PYY response at each meal size (P < 0.05 at all levels). The ratio of plasma PYY(1-36) to PYY(3-36) was similar in normal-weight and obese subjects. The effect on food intake and satiety of graded doses of exogenous PYY(3-36) was also evaluated in 12 human volunteers. Stepwise increasing doses of exogenous PYY(3-36) in humans caused a graded reduction in food intake (R2 = 0.38; P < 0.001). In high-fat-fed (HF) mice that became obese and low-fat-fed mice that remained normal weight, we measured plasma PYY, tissue PYY, and PYY mRNA levels and assessed the effect of exogenous administered PYY(3-36) on food intake in HF mice. HF mice remained sensitive to the anorectic effects of exogenous ip PYY(3-36). Compared with low-fat-fed fed mice, the HF mice had lower endogenous plasma PYY and higher tissue PYY but similar PYY mRNA levels, suggesting a possible reduction of PYY release. Thus, fasting and postprandial endogenous plasma PYY levels were attenuated in obese humans and rodents. The PYY(3-36) infusion study showed that the degree of plasma PYY reduction in obese subjects were likely associated with decreased satiety and relatively increased food intake. We conclude that obese subjects have a PYY deficiency that would reduce satiety and could thus reinforce their obesity.

Abstract
Several lines of evidence suggest that wetlands may be a major source of methylmercury (MeHg) to receiving waters, perhaps explaining the strong correlation between concentrations of waterborne MeHg and dissolved organic carbon (DOC) in regions such as northern Wisconsin. We evaluated the relative importance of wetland export in the MeHg budget of a wetland-dominated lake in northern Wisconsin using mass balance. Channelized runoff from a large headwater wetland was the major source of water and total mercury (HgT) to the lake during the study period. The wetland also exported MeHg in high concentrations (0.2-0.8 ng L(-1)), resulting in an export rate similar to those reported for other northern wetlands (ca. 0.3 microg MeHg m(-2) y(-1)). Yet, based on intensive sampling during 2002, the mass of MeHg that accumulated in the lake during summer was an order of magnitude greater than the export of MeHg from the wetland to the lake. Hence, a large in-lake source of MeHg is inferred from the mass balance. Most of the accumulated MeHg built-up in anoxic hypolimnetic waters; and the build-up was roughly balanced by losses of inorganic Hg (Hg(II)) implying a chemical transformation within the anoxic water column. An abundance of sulfate-reducing bacteria (SRB) in hypolimnetic waters, established by DNA analysis of the pelagic microbial community, along with a previous report documenting high methylation rates in the hypolimnion of this lake (ca. 10% d(-1)), suggest that this transformation was microbially mediated. These findings indicate that the direct effect of wetland runoff may be outweighed by indirect effects on the lacustrine MeHg cycle, enhancing the load of Hg(II), the activity of SRB, and the retention of MeHg, especially in northern lakes with flushing times longer than six months.

Abstract
OBJECTIVE To examine the effect of antenatal steroid exposure and in utero inflammation on the development of severe intraventricular haemorrhage, periventricular leukomalacia and long-term neurological outcome in infants less than 30 completed weeks gestation. METHOD Infants less than 30 completed weeks gestation from January 1996 to July 2001 were identified from a prospectively managed database. Placental pathology was reviewed for the presence or absence of chorioamnionitis and funisitis. Infants were divided into three groups depending on the degree of exposure to fetal inflammation (no inflammation, chorioamnionitis only and chorioamnionitis and funisitis). Data relating to gestational age, birthweight, sex, antenatal steroid exposure, surfactant treatment, days of positive pressure ventilation and days of oxygen requirement were collected. Cerebral ultrasound studies were examined for evidence of intraventricular or intraparenchymal echodensity and periventricular leukomalacia. Long-term neurological outcome was assessed by neurological examination for cerebral palsy and by Griffiths Mental Developmental Assessment for general developmental quotient. RESULTS Two hundred and twenty infants were identified. The mean gestational age was 27.7 weeks and the mean birthweight 1092 g. Seventy-two per cent of mothers had received a complete course of antenatal steroids. The risk of Grade III intraventricular haemorrhage or intraparenchymal echodensity was associated with exposure to in utero inflammation if a complete course of antenatal steroids had not been received (P = 0.002). This association did not exist if a complete course of antenatal steroids was given (P = 0.62). Fourteen infants had cerebral palsy (7%). The presence of cerebral palsy was also associated with in utero inflammation in the absence of complete antenatal steroid cover (P = 0.03) and not in the presence of complete cover (P = 0.59). The mean general developmental quotient on Griffiths Mental Developmental Assessment at 12 months or 3 years was not affected by exposure to in utero inflammation regardless of antenatal steroid exposure. CONCLUSION Risk of intraventricular haemorrhage or intraparenchymal echodensity and cerebral palsy was associated with in utero inflammation in the absence of a complete course of antenatal steroids. A complete course of antenatal steroids appeared to extinguish any association between in utero inflammation and adverse neurological outcome.

Abstract
OBJECTIVE To examine the association between chorioamnionitis with or without funisitis and bronchopulmonary dysplasia in infants less than 30 completed weeks gestation given the current standards of antenatal steroid and surfactant use. METHODS Infants included in the study were those delivered at less than 30 completed weeks gestation from January 1996 to July 2001, identified from a prospectively managed database. Placental pathology was reviewed for the presence or absence of chorioamnionitis and funisitis. Infants were divided into three groups depending on degree of exposure to fetal inflammation (no inflammation, chorioamnionitis only and chorioamnionitis and funisitis). Data relating to gestational age, sex, antenatal steroid exposure, surfactant treatment, days of positive pressure ventilation and days of oxygen required were collected. Bronchopulmonary dysplasia was defined as death due to respiratory failure or any oxygen requirement at 36 weeks postmenstrual age. RESULTS Two hundred and forty-one infants were included in the study. The mean gestational age was 27.7 weeks and mean birthweight 1089 g. One hundred and sixty-one infants were not exposed to any in utero inflammation, 40 showed chorioamnionitis and 40 showed chorioamnionitis and funisitis. There was no significant difference between antenatal steroid and surfactant treatment between the three groups. There was no significant difference between the three groups in the development of bronchopulmonary dysplasia. Low gestational age was the most significant predictor of developing bronchopulmonary dysplasia. CONCLUSION The risk of developing bronchopulmonary dysplasia is not increased following exposure to chorioamnionitis or funisitis in the context of current antenatal steroid and surfactant use. The most significant predictor for developing bronchopulmonary dysplasia is gestational age at the time of delivery.

Abstract
OBJECTIVE To determine readmission and recurrence rates of women admitted to psychiatric hospital with their babies, and index factors predicting subsequent course. METHOD A total of 66 women were followed up after 10 years. Information was obtained from structured interviews or other personal contact, and from general practitioners and hospital notes. Psychiatric diagnoses were made according to Research Diagnostic Criteria (RDC). Outcome and predictive factors were investigated using survival analysis. RESULTS A recurrence rate of 87.2%, and a readmission rate of 63.3% were found. Readmissions were more common after index schizophrenia than other diagnoses. The strongest predictor of readmission was previous psychiatric history. Among 27 subsequent pregnancies, puerperal recurrence was high among those with index psychoses (75-80%), but lower among those with index depression (27.3%). CONCLUSION The recurrence rate is high, with a moderate readmission rate predicted by past psychiatric history. Continuing clinical vigilance over the long-term is required for these patients.

Abstract
Renal impairment occurs in neonates receiving indomethacin for treatment of patent ductus arteriosus. Inhibition of cyclooxygenase within the neonatal kidney results in decreased prostaglandin synthesis and consequent reduction in renal perfusion. Indomethacin has been reported to cause short-term reduction in glomerular filtration that resolves after cessation of the drug. There is little information on the long-term effects of postnatal exposure to indomethacin. The aim of this study was to determine the incidence of renal impairment in infants treated with indomethacin in a single center, to determine whether there is evidence of renal impairment on day 30 or at discharge, and to identify risk factors for renal impairment. In a retrospective study, infants of less than 30 weeks completed gestation who received indomethacin to close the ductus arteriosus were matched with infants of the same gestation, birth weight, and severity of illness. Serum creatinine and glomerular filtration rates (GFR) were obtained prior to commencing indomethacin and on days 2, 7, and 30 following indomethacin administration. Acute renal failure was defined as an increase in creatinine of greater than 25%. Of those infants who were less than 30 weeks completed gestation, 24% had acute renal failure following indomethacin administration. There was a significant elevation in serum creatinine on day 2 and day 7 ( P<0.0001, P=0.002) and a decrease in GFR on day 2 and day 7 ( P<0.0001, P=0.01) following administration of indomethacin. Renal function had normalized by day 30 or discharge. The incidence of acute renal failure in neonates treated with indomethacin is clinically significant. Renal function returns to normal by day 30. Linear regression found no statistical significance for gestational age, day of indomethacin dosing, Clinical Risk Index for Babies (CRIB) score, and presence of an umbilical artery catheter to confound the effect of indomethacin on renal function.

Abstract
Renal tubular dysgenesis is a rare disorder of differentiation of the fetal kidney. The condition has previously been reported as a postmortem diagnosis in infants who have had oligohydramnios commencing after 20 weeks gestation and have died of renal or respiratory failure shortly after birth with a clinical description of Potter sequence. The absence of clinically significant pulmonary hypoplasia in our case serves to emphasize that renal tubular dysgenesis, fetal anuria and long-standing oligohydramnios can occur without pulmonary insufficiency. The coexistence of renal tubular dysgenesis with neonatal hemochromatosis has been previously described in four published cases. The link between these two rare conditions is clinically important if dialysis or liver transplantation is considered in infants with hepatic and renal failure. Antemortem diagnosis by renal biopsy in our case enabled parental counseling and avoided the inappropriate use of peritoneal dialysis.

Abstract
OBJECTIVE We compared early pulmonary (18)fluorodeoxyglucose ((18)FDG) uptake in infants who had very low birth weight with and without exposure to intrauterine inflammation by using positron emission tomography (PET). A secondary goal was to correlate (18)FDG uptake with later death or bronchopulmonary dysplasia. METHODS Within 72 hours of birth, 22 singleton infants between 25 and 30 weeks of gestation had a thoracic PET scan after intravenous (18)FDG. Influx constants (K(i)) for (18)FDG were determined. Placental histology assessed exposure to intrauterine inflammation. RESULTS Chorioamnionitis was found in 13 infants. Seven of these infants also had evidence of funisitis. No inflammation was detected in the remaining nine infants. Median (minimum, maximum) thoracic K(I) was 0.008 (0.006, 0.011) mL/min/mL in infants with funisitis, 0.006 (0.002, 0.008) in infants with chorioamnionitis only, and 0.006 (0.001, 0.015) in infants with no evidence of intrauterine inflammation (P=.16). No relation was found between K(i) and later death or bronchopulmonary dysplasia. Cord blood interleukin-6 was elevated in newborns with placental inflammation (P=.014). CONCLUSION Early thoracic PET scanning for metabolically active inflammatory cells does not differ between infants with and without exposure to intrauterine inflammation. Evidence of early intrapulmonary sequestration of inflammatory cells in some infants without chorioamnionitis points to the complex etiology of postnatal inflammation.

Abstract
As schizophrenia is genetically and clinically heterogeneous, systematic investigations are required to determine whether ICD-10 or DSM-IV categorical diagnoses identify a phenotype suitable and sufficient for genetic research, or whether correlated phenotypes incorporating neurocognitive performance and personality traits provide a phenotypic characterisation that accounts better for the underlying variation. We utilised a grade of membership (GoM) model (a mathematical typology developed for studies of complex biological systems) to integrate multiple cognitive and personality measurements into a limited number of composite graded traits (latent pure types) in a sample of 61 nuclear families comprising 80 subjects with ICD-10/DSM-IV schizophrenia or schizophrenia spectrum disorders and 138 nonpsychotic first-degree relatives. GoM probability scores, computed for all subjects, allowed individuals to be partly assigned to more than one pure type. Two distinct and contrasting neurocognitive phenotypes, one familial, associated with paranoid schizophrenia, and one sporadic, associated with nonparanoid schizophrenia, accounted for 74% of the affected subjects. Combining clinical diagnosis with GoM scores to stratify the entire sample into liability classes, and using variance component analysis (SOLAR), in addition to parametric and nonparametric multipoint linkage analysis, we explored candidate regions on chromosomes 6, 10 and 22. The results indicated suggestive linkage for the familial neurocognitive phenotype (multipoint MLS 2.6 under a low-penetrance model and MLS>3.0 under a high-penetrance model) to a 14 cM area on chromosome 6, including the entire HLA region. Results for chromosomes 10 and 22 were negative. The findings suggest that the familial neurocognitive phenotype may be a pleiotropic expression of genes underlying the susceptibility to paranoid schizophrenia. We conclude that use of composite neurocognitive and personality trait measurements as correlated phenotypes supplementing clinical diagnosis can help stratify the liability to schizophrenia across all members of families prior to linkage, allow the search for susceptibility genes to focus selectively on subsets of families at high genetic risk, and augment considerably the power of genetic analysis.

Abstract
OBJECTIVES To quantify long term impairment after neonatal meningitis. DESIGN Longitudinal case-control study over 9-10 years. SUBJECTS AND METHODS A total of 111 children who had suffered neonatal meningitis were seen and compared with 113 matched controls from their birth hospital and 49 controls from general practices. Assessments included the WISC III(UK), movement assessment battery for children (mABC), audiometry, vision testing, and social and medical data. Statistical analysis was by multiple regression, analysis of variance, and chi(2) tests. RESULTS Some 10.8% of cases had a severe and 9% a moderate overall outcome compared with 0% and 1.8% for the hospital controls. The mean intelligence quotient (IQ) of the cases (88.8) was significantly less than that of the hospital controls (99.4) or the GP controls (99.6). The mABC score was significantly worse for the cases (7.08) than the hospital (5) or GP (4) controls. Some 3.6% of cases had sensorineural hearing loss, 2.7% had persisting hydrocephalus; no controls did. Some 5.4% of cases and 1.7% of hospital controls had treatment for seizures. CONCLUSIONS Severe neurodisability and milder motor and psychometric impairment result from neonatal meningitis. Both clinical follow up and comprehensive developmental assessment are needed after this disease.

Abstract
Against a background of increasing regulation regarding access to medical information and the presentation of patients' confidentiality, the case of genetic information raises interesting questions about whether the application of general rules is appropriate in all situations. Whilst all genetic information is not equally sensitive, some of it is highly predictive. It also allows deductions to be made about other family members. It may not be regarded as particularly sensitive when compared to other types of medical information and those to whom it applies may not be as anxious about preserving their confidentiality as compared with-for example, the prospect of seeing research into cause and cures for rare diseases put in hand. These distinctions also find resonance with the general public. Resolving conflicting tensions will require subtlety, not a blunt "one size fits all" model.

Abstract
OBJECTIVE To compare patterns of clinical activity amongst existing staff in two inner-city community mental health teams before and after their enhancement with extra resources using a new activity schedule containing 11 comprehensive and mutually exclusive practice categories. METHOD Patterns of clinical activity amongst existing members of two inner-London community mental health teams were compared before and after the addition of extra resources. RESULTS The amount of time spent in face-to-face contact with patients and carers showed no meaningful change following team enhancement. Patterns of clinical activity amongst team members remained relatively static. CONCLUSION Adding resources to community mental teams without considering how to target the time released amongst existing staff may reduce their capacity to work more innovatively.

Abstract
OBJECTIVE To investigate the association between maternal anxiety and uterine artery resistance index (RI) at 20 weeks of gestation. METHODS Uterine artery blood flow was assessed using color Doppler ultrasound and maternal anxiety was measured using the Hospital Anxiety and Depression (HAD) scale in 96 healthy primigravid women attending consecutively for their routine 20-week anomaly scan. RESULTS The mean uterine artery RI was 0.54 (95% confidence interval, 0.52-0.56) and the median HAD anxiety score was 6 (range, 0-20). There was no association between RI and anxiety scores (r = 0.09, P = 0.36). Women scoring as definite cases of anxiety did not have a significantly elevated uterine artery RI or increased frequency of waveform notching compared to women with doubtful or no anxiety. CONCLUSIONS The data of this study do not suggest a significant association between maternal anxiety and uterine artery RI at 20 weeks of gestation in healthy primigravid women with normally developing pregnancies. A prospective cohort study would be useful to determine the nature of the relationship between maternal anxiety, alteration in uterine artery blood flow and abnormal pregnancy outcome.
