Abstract
Abstract
Introduction: Breast MRI in the workup of a new breast cancer diagnosis is both a valuable and costly imaging study. The decision to obtain a breast MRI is often made by the surgeon who is referred the newly diagnosed breast cancer patient. That is followed by a delay in their management due to scheduling the MRI. Our breast center program leadership developed a protocol to move the time of MRI prior to the surgeon's evaluation while avoiding unnecessary breast MRIs ordered by some well-intentioned primary care providers. Coordinating a breast MRI protocol can optimize timely performance of breast MRI, guiding primary care to become the ordering clinician while avoiding unnecessary breast MRIs.
Methods: Recognizing a delay in the journey of newly diagnosed breast cancer patients that have their breast MRI ordered only after the multidisciplinary conference or surgical consultation, we developed a protocol to improve timeliness of care. Guidelines were identified by our breast program leadership when a newly diagnosed breast cancer patient would warrant a breast MRI. Agreed upon indicators included dense breast tissue, invasive lobular breast cancer, patients typically under 50 years old, and vague imaging of primary lesions. When these findings were identified, the radiologist included a statement with the core needle biopsy report. It stated that our breast program leadership identified this patient as benefiting from a breast MRI ordered soon after the positive biopsy. This avoided the issue of self-referral since our breast leadership created the guidelines. The message went to the primary care provider who now ordered the breast MRI prior to conference or surgical consultation. We examined sixty consecutive patients from two time periods, half before and half after institution of the MRI protocol.
Results: Prior to this policy, patients who needed breast MRI would obtain the study on average 12 days after our multidisciplinary breast conference (MDC), while after institution of the policy breast MRI was obtained 3 days PRIOR to conference. Before only 43% of necessary breast MRIs were ordered prior to surgical consultation while after the protocol 100% of breast MRIs were ordered PRIOR to surgical consultation. Before the protocol rarely did primary care order breast MRIs. After the protocol primary care providers ordered 80% of all breast MRIs. While ordering more breast MRIs, primary care ordered less unnecessary studies. After the protocol was instituted, inappropriate studies as determined by the MDC decreased from 21% deemed unnecessary to only 10%.
Conclusions: Institution of a breast MRI ordering guideline by the breast program leadership with participation of primary care had the benefits of obtaining the breast MRI before the multidisciplinary conference and/or surgical consultation while avoiding unnecessary breast MRI orders. Institution of a breast MRI protocol enhances patient care, eliminates delays in treatment, avoids unnecessary tests, shifts appropriate care to primary care providers and allows initial surgical consultation to have all the data necessary to make definitive decisions. This quality improvement effort via program leadership improved comprehensive care.

Abstract
Risky decision-making is characteristic of drug users, but little is known about the effects of circumstances, such as abstinence, on risky choice behavior in human drug users. We hypothesized that cocaine users would make more risky choices for cocaine (defined as taking a chance to receive a large number of cocaine doses as opposed to choosing to receive a fixed amount of cocaine) after 3 or 7 days of cocaine abstinence, compared to 1 day of cocaine abstinence. Six male nontreatment-seeking current cocaine smokers were enrolled in a 21-day inpatient within-subject study. Participants repeatedly smoked six 25 mg doses of cocaine during a training session and were instructed that they would be making decisions about smoking this dose throughout the study. After 1, 3 and 7 days of cocaine abstinence, participants completed a computerized task in which they repeatedly decided between receiving a guaranteed number of cocaine doses (between 1 and 5; fixed option) or receiving a chance (0.13 to 0.75) to smoke a larger number of cocaine doses (probabilistic option). After completing the computerized task, one of the participants' choices was randomly implemented and they smoked either the fixed number of cocaine doses or had the specified chance to smoke the greater number of doses. Contrary to our hypothesis, 5 of the 6 participants made fewer risky choices after 3 and 7 days of cocaine abstinence compared to one day of abstinence suggesting greater risk-aversion. Thus, even during cocaine abstinence cocaine users make rational decisions related to their drug use.

Abstract
OBJECTIVE We tested the ability of a type 1 diabetes (T1D) genetic risk score (GRS) to predict progression of islet autoimmunity and T1D in at-risk individuals. RESEARCH DESIGN AND METHODS We studied the 1,244 TrialNet Pathway to Prevention study participants (T1D patients' relatives without diabetes and with one or more positive autoantibodies) who were genotyped with Illumina ImmunoChip (median [range] age at initial autoantibody determination 11.1 years [1.2-51.8], 48% male, 80.5% non-Hispanic white, median follow-up 5.4 years). Of 291 participants with a single positive autoantibody at screening, 157 converted to multiple autoantibody positivity and 55 developed diabetes. Of 953 participants with multiple positive autoantibodies at screening, 419 developed diabetes. We calculated the T1D GRS from 30 T1D-associated single nucleotide polymorphisms. We used multivariable Cox regression models, time-dependent receiver operating characteristic curves, and area under the curve (AUC) measures to evaluate prognostic utility of T1D GRS, age, sex, Diabetes Prevention Trial-Type 1 (DPT-1) Risk Score, positive autoantibody number or type, HLA DR3/DR4-DQ8 status, and race/ethnicity. We used recursive partitioning analyses to identify cut points in continuous variables. RESULTS Higher T1D GRS significantly increased the rate of progression to T1D adjusting for DPT-1 Risk Score, age, number of positive autoantibodies, sex, and ethnicity (hazard ratio [HR] 1.29 for a 0.05 increase, 95% CI 1.06-1.6; P = 0.011). Progression to T1D was best predicted by a combined model with GRS, number of positive autoantibodies, DPT-1 Risk Score, and age (7-year time-integrated AUC = 0.79, 5-year AUC = 0.73). Higher GRS was significantly associated with increased progression rate from single to multiple positive autoantibodies after adjusting for age, autoantibody type, ethnicity, and sex (HR 2.27 for GRS >0.295, 95% CI 1.47-3.51; P = 0.0002). CONCLUSIONS The T1D GRS independently predicts progression to T1D and improves prediction along T1D stages in autoantibody-positive relatives.

Abstract
Bipedal ornithischian dinosaurs from the Upper Jurassic Morrison Formation are rare, forming only about 15% of the dinosaur specimens. Nevertheless, one of them was among the first dinosaurs named from what was then the ‘’Atlantosaurus Beds’’ of Colorado. Collecting and restudy for 140 years has increased the diversity from the initial 1877 discovery to the currently valid four genera and six species, viz., Fruitadens haagaroum, Nanosaurus agilis, Camptosaurus dispar, C. aphanoecetes, Dryosaurus altus, and D. elderae, which we briefly review. We demonstrate that the enigmatic Nanosaurus agilis is the senior name for Drinker nisti, Othnielosaurus consors, and Othnielia rex. In addition, a new species, Dryosaurus elderae is proposed for the Dryosaurus specimens from Dinosaur National Monument that are characterized by elongate cervical verebrae and a long, low ilium among other features.

Abstract
Minmi is the only known genus of ankylosaurian dinosaur from Australia. Seven specimens are known, all from the Lower Cretaceous of Queensland. Only two of these have been described in any detail: the holotype specimen Minmi paravertebra from the Bungil Formation near Roma, and a near complete skeleton from the Allaru Mudstone on Marathon Station near Richmond, preliminarily referred to a possible new species of Minmi. The Marathon specimen represents one of the world’s most complete ankylosaurian skeletons and the best-preserved dinosaurian fossil from eastern Gondwana. Moreover, among ankylosaurians, its skull is one of only a few in which the majority of sutures have not been obliterated by dermal ossifications or surface remodelling. Recent preparation of the Marathon specimen has revealed new details of the palate and narial regions, permitting a comprehensive description and thus providing new insights cranial osteology of a basal ankylosaurian. The skull has also undergone computed tomography, digital segmentation and 3D computer visualisation enabling the reconstruction of its nasal cavity and endocranium. The airways of the Marathon specimen are more complicated than non-ankylosaurian dinosaurs but less so than derived ankylosaurians. The cranial (brain) endocast is superficially similar to those of other ankylosaurians but is strongly divergent in many important respects. The inner ear is extremely large and unlike that of any dinosaur yet known. Based on a high number of diagnostic differences between the skull of the Marathon specimen and other ankylosaurians, we consider it prudent to assign this specimen to a new genus and species of ankylosaurian. Kunbarrasaurus ieversi gen. et sp. nov. represents the second genus of ankylosaurian from Australia and is characterised by an unusual melange of both primitive and derived characters, shedding new light on the evolution of the ankylosaurian skull.

Abstract
Discovery of a pelvis attributed to the Late Jurassic armor-plated dinosaur Gargoyleosaurus sheds new light on the origin of the peculiar non-vertical, broad, flaring pelvis of ankylosaurs. It further substantiates separation of the two ankylosaurs from the Morrison Formation of the western United States, Gargoyleosaurus and Mymoorapelta. Although horizontally oriented and lacking the medial curve of the preacetabular process seen in Mymoorapelta, the new ilium shows little of the lateral flaring seen in the pelvis of Cretaceous ankylosaurs. Comparison with the basal thyreophoran Scelidosaurus demonstrates that the ilium in ankylosaurs did not develop entirely by lateral rotation as is commonly believed. Rather, the preacetabular process rotated medially and ventrally and the postacetabular process rotated in opposition, i.e., lateral and ventrally. Thus, the dorsal surfaces of the preacetabular and postacetabular processes are not homologous. In contrast, a series of juvenile Stegosaurus ilia show that the postacetabular process rotated dorsally ontogenetically. Thus, the pelvis of the two major types of Thyreophora most likely developed independently. Examination of other ornithischians show that a non-vertical ilium had developed independently in several different lineages, including ceratopsids, pachycephalosaurs, and iguanodonts. Therefore, a separate origin for the non-vertical ilium in stegosaurs and ankylosaurs does have precedent.

Abstract
This study examined the treatment history and intention to seek treatment among 489 individuals interested in substance use disorder clinical trial participation. Opioid and cocaine users were more likely than cannabis users to report having received treatment for substance use in the past and more likely than cannabis users to report planning to seek treatment for substance use before exposure to recruitment advertising. Free cost was the aspect of clinical trial participation that most influenced the decision to make an intake evaluation appointment for opioid-dependent patients as compared with cocaine- and cannabis-dependent participants, and the availability of individual psychotherapy most influenced those who were cannabis dependent. Cannabis-dependent individuals evaluated for clinical trial participation reported that recruitment advertising was an important factor in leading them to seek treatment. These results have implications for clinical trial recruitment and public health efforts directed at encouraging cannabis-dependent individuals to seek treatment.

Abstract
OBJECTIVE To conduct a quasi-experimental comparison of early clinical outcomes between injectable, sustained-release, depot naltrexone formulation versus oral naltrexone maintenance therapy in individuals with opiate dependence. METHOD Early retention in treatment and urine-confirmed opiate use in the first 8 weeks postdetoxification were compared between patients (diagnosed as opiate-dependent according to DSM-IV criteria) participating in 2 concurrently run randomized clinical trials of oral (n = 69; patients treated from September 1999 to May 2002) and long-acting injectable (n = 42; patients treated from November 2000 to June 2003) naltrexone maintenance therapy with psychosocial therapy. RESULTS Long-acting injectable naltrexone produced significantly better outcome than oral naltrexone on days retained in treatment (F(1,106) = 6.49, P = .012) and for 1 measure of opiate use (F(1,106) = 5.26, P = .024); other measures were not significantly different, but differences were in the same direction. In subanalyses, there were interaction effects between baseline heroin use severity and type of treatment. In subanalyses, heroin users with more severe baseline use showed better retention with oral naltrexone maintenance therapy combined with intensive psychotherapy (behavioral naltrexone therapy) as compared to retention shown by severe heroin users treated with long-acting naltrexone injections combined with standard cognitive-behavioral therapy (χ²(1)= 9.31, P = .002); less severe heroin users evidenced better outcomes when treated with long-acting injectable naltrexone. CONCLUSIONS This quasi-experimental analysis provides tentative indications of superior outcomes for heroin-dependent patients treated with long-acting injectable naltrexone compared to oral naltrexone. The finding that heroin users with more severe baseline use achieved better outcomes with oral naltrexone is most probably attributable to the intensive nature of the psychosocial treatments provided and points to the opportunity for continued research in augmenting injectable naltrexone with psychosocial strategies to further improve outcome, especially in individuals with more severe use. The results should be considered exploratory given the quasi-experimental nature of the study.

Abstract
We describe three patients with congenital disorder of glycosylation (CDG) type Ia, all of whom had persistent hyperinsulinaemic hypoglycaemia responding to diazoxide therapy as a common feature. The first patient, an infant girl, presented with recurrent vomiting, failure to thrive, liver impairment, hypothyroidism and a pericardial effusion. The second patient, also female, had a milder disease with single organ involvement, presenting as isolated hyperinsulinaemic hypoglycaemia, not associated with any cognitive impairment. The third patient, a boy presented with multi-organ manifestations including congenital hypothyroidism, persistent hyperinsulinaemic hypoglycaemia, coagulopathy, olivopontocerebellar hypoplasia and recurrent pancreatitis. All three patients had a type 1 serum transferrin isoform pattern, and were subsequently found to have low phosphomannomutase activity, confirming the diagnosis of CDG type Ia. Our findings emphasize that CDG should be considered as a differential diagnosis in patients with persistent hyperinsulinaemic hypoglycaemia and that it may even occasionally be the leading symptom in CDG Ia.

Abstract
Glutaric aciduria type I (GA I), a cerebral organic acidaemia with the potential for severe neurological consequences, can now be detected by tandem mass spectrometry newborn screening. Early detection with implementation of careful management strategies appears to lessen the likelihood of neurological damage. We assessed the outcome in all 10 GA I patients detected in New South Wales during the last decade. Three patients were detected clinically and 7 by newborn screening. Diagnosis was confirmed by detection of significantly elevated urinary 3-hydroxybutyrate and glutarate in urine, isolated elevation of glutarylcarnitine in plasma, typical clinical and MRI findings in several, and mutation analysis or enzyme analysis on cultured skin fibroblasts in 4 cases. The birth frequency was 1:90,000. Following diagnosis, treatment was initiated in all children with oral carnitine (100 mg/kg per day) and a low-protein diet supplemented with a lysine-free, low-tryptophan amino acid formula. Disability was assessed in fields of motor, cognitive and speech development and scored according to Kyllerman. Clinically diagnosed patients were all symptomatic, with severity scores (out of 9) of 3, 5 and 9. Six of seven patients detected by newborn screening are asymptomatic, 4 being aged 2-6 years. One patient had a severe decompensation at 7 months, despite full management advice and treatment, and later died. Our data support previous findings that early diagnosis reduces neurological complications, but show that even with early diagnosis and careful management severe complications may ensue in some.

Abstract
UNLABELLED Opioid dependence is a growing public health problem. Maintenance on the antagonist naltrexone for clinic- or office-based treatment of opioid dependence is plagued by high rates of relapse. This paper identifies critical determinants of lapses to opioid use during naltrexone maintenance. Time retained in treatment was examined as a function of whether lapses to opioid use occurred while adherent to naltrexone (blocked use), or after having missed naltrexone doses (unblocked). METHOD Participants (N=83) met DSM-IV criteria for opioid dependence and identified a significant other willing to participate in their treatment. Following inpatient detoxification, participants were enrolled in a 26-week outpatient course of therapy and naltrexone maintenance. RESULTS Patients with unblocked use had a very high rate of dropout (10% retained at 6 months), dropout usually occurring within 2 weeks after unblocked use. Patients with only blocked use had less dropout (33% retained at 6 months). However, episodes of blocked use were often followed by unblocked use and dropout. CONCLUSIONS During naltrexone maintenance for opioid dependence unblocked opioid use calls for immediate intervention, such as detoxification or switching to the partial agonist buprenorphine. Episodes of blocked use warrant increased clinical attention, such as direct observation of naltrexone ingestion, increased dose, or increased intensity of treatment contact. Maintenance on oral naltrexone is a fragile treatment because it is so easily undermined by episodes of opioid use while non-compliant. New long-acting injectable or implantable formulations of naltrexone may address this limitation and should be investigated for treatment of opioid dependence.

Abstract
A newborn female presented on the first day of life with clinical and biochemical findings consistent with multiple acyl-CoA dehydrogenase deficiency (MADD). Riboflavin supplementation corrected the biochemical abnormalities 24 h after commencing the vitamin. In vitro acylcarnitine profiling in intact fibroblasts both in normal and riboflavin depleted media showed normal oxidation of fatty acids excluding defects in electron transfer flavoprotein (ETF), or ETF ubiquinone oxidoreductase (ETF:QO), or a genetic abnormality in flavin metabolism. In addition, sequencing of the genes encoding ETF and ETF:QO in the proband did not reveal any pathogenic mutations. Determination of the maternal riboflavin status after delivery showed that the mother was riboflavin deficient. Repeat testing done two years after the infant's birth and while on a normal diet showed that the mother was persistently riboflavin deficient and showed a typical MADD profile on plasma acylcarnitine testing. A possible genetic defect in riboflavin transport of metabolism in the mother is postulated to be the cause of the transient MADD seen in the infant. Sequencing of the SLC16A12, RFK and FLAD1 genes encoding key enzymes in riboflavin transport of metabolism in the mother did not identify any pathogenic mutations. The underlying molecular basis of the mother's defect in riboflavin metabolism remains to be established.

Abstract
A newborn boy with family history of severe ornithine transcarbamylase (OTC) deficiency was investigated prospectively and managed aggressively at birth based on an existing protocol for at risk neonates. Undetectable citrulline levels at birth suggested that the infant was affected; however, normal plasma glutamine and urine orotic acid levels confused the diagnosis to some extent. Mutation testing confirmed that the patient did not have OTC deficiency. Thus the low plasma citrulline level did not validate our initial biochemical suspicion of OTC deficiency, and this highlights the importance of considering all available clinical, biochemical and molecular evidence in determining disease status.

Abstract
Diagnosis of Non-Ketotic Hyperglycinemia by MSMS newborn screening might benefit patients with post-neonatal presentation. We screened 733,527 babies over eight years, and nine babies were subsequently diagnosed with NKHG. Two had newborn glycine levels above our cut-off and presented within 72 h. The remaining patients could not have been diagnosed by newborn screening without an unacceptably high recall rate. We conclude that babies with NKHG are not usually identifiable by current newborn screening strategies.

Abstract
Idiopathic pulmonary fibrosis (IPF)/usual interstitial pneumonia (UIP) is the severest form of idiopathic interstitial pneumonia for which therapeutic targets are needed. Surgical lung biopsy specimens from IPF/UIP patients exhibit focal expression of CC chemokine receptor (CCR) 7, but the identity of these CCR7-positive cells is unknown. The purpose of the present study was to examine the functional and signalling significance of CCR7 expression of primary fibroblasts grown from IPF/UIP and normal surgical lung biopsy specimens. Primary fibroblasts were cultured from surgical lung biopsy specimens from IPF/UIP and normal patients. Fibroblasts treated with or without CC chemokine ligand (CCL) 21 were analysed for functional, transcriptional and proteomic differences using immunocytochemical analysis, gene arrays, Taqman real-time PCR, and migration, proliferation and Western blot assays. CCR7 was expressed by IPF/UIP fibroblasts, but not normal fibroblasts. IPF/UIP fibroblasts, but not normal fibroblasts, showed significant migratory and proliferative responses when exposed to CCL21, which were inhibited by pertussis toxin or neutralising antibodies to CCR7. Exposure of IPF/UIP fibroblasts to CCL21 altered the phosphorylation status of mitogen-activated protein kinase kinase 1/2, extracellular signal-regulated kinase 1/2 and ribosomal S6 kinase (90 kDa) in these cells; this was abrogated by pertussis toxin or CCR7-specific small interfering RNA. Together, these data demonstrate that CC chemokine ligand 21 modulates the functional properties of idiopathic pulmonary fibrosis/usual interstitial pneumonia fibroblasts, but not normal fibroblasts.

Abstract
The New South Wales state-wide newborn screening programme has offered comprehensive screening for inborn errors of metabolism, including MSUD, using electrospray tandem mass spectrometry since 1998. Over this period, a number of patients with classic MSUD have been identified with subsequent good neurological outcome. We describe two patients with an intermediate form of MSUD who presented later in childhood. Retrospective review of their newborn screening results demonstrates that the diagnosis could not have been made by current newborn screening. Their neurological outcome is much less satisfactory. Despite the usefulness of expanded newborn screening programmes in detecting severe neonatal presentations of inborn errors of metabolism, partial enzyme deficiencies may not be detected. Metabolic diseases still need to be considered in appropriate clinical situations later in life.

Abstract
Right hemisphere activation during functional imaging studies of language has frequently been reported following left hemisphere injury. Few studies have anatomically characterized the specific right hemisphere structures engaged. We used functional MRI (fMRI) with verbal fluency tasks in 12 right-handed patients with left temporal lobe epilepsy (LTLE) and 12 right-handed healthy controls to localize language-related activity in the right inferior frontal gyrus (RIFG). During the phonemic task, LTLE patients activated a significantly more posterior region of the right anterior insula/frontal operculum than healthy controls (P = 0.02). Activation of the left inferior frontal gyrus (LIFG) did not differ significantly between the two groups. This suggests that, following left hemisphere injury, language-related processing in the right hemisphere differs from that with a functionally normal left hemisphere. The localization of activation in the left and right inferior frontal gyri was determined with respect to the anatomical sub-regions pars opercularis (Pop), pars triangularis (Ptr) and pars orbitalis (Por). In the LIFG, both healthy controls (8 out of 12) and LTLE patients (9 out of 12) engaged primarily Pop during phonemic fluency. Activations in the RIFG, however, were located mostly in the anterior insula/frontal operculum in both healthy controls (8 out of 12) and LTLE patients (8 out of 12), albeit in distinct regions. Mapping the locations of peak voxels in relation to previously obtained cytoarchitectonic maps of Broca's area confirmed lack of homology between activation regions in the left and right IFG. Verbal fluency-related activation in the RIFG was not anatomically homologous to LIFG activation in either patients or controls. To test more directly whether RIFG activation shifts in a potentially adaptive manner after left hemisphere injury, fMRI studies were performed in a patient prior to and following anatomical left hemispherectomy for the treatment of Rasmussen's encephalitis. An increase in activation magnitude and posterior shift in location were found in the RIFG after hemispherectomy for both phonemic and semantic tasks. Together, these results suggest that left temporal lobe injury is associated with potentially adaptive changes in right inferior frontal lobe functions in processing related to expressive language.

Abstract
We have screened 13 patients with neurological abnormalities and 3-methylglutaconic aciduria (3MGA) for mutations in the OPA3 gene, which are known to be the cause of Costeff syndrome (optic atrophy, chorea and spasticity; type III 3MGA). We aimed to explore whether mutations in the OPA3 gene are present in patients with 3MGA but without classic Costeff syndrome. OPA3 mutations (IVS1-1G>C) were identified in 2 patients with the classic phenotype of type III 3MGA, but not in the other 11 patients with differing non-Costeff phenotypes associated with developmental delay and neurological signs and symptoms as described. We identified a previously described sequence variation in the OPA3 gene (c.231T>C) in 12/13 patients. The alteration was homozygous in 8/12 and heterozygous in 4/12. This alteration was also found in 60 of 98 normal control alleles. In a single patient, a novel sequence variation in the 5' UTR was identified, (c.-38A>G). Our studies suggest that the c.231T>C sequence variation is of no clinical significance, whereas the significance of the 5' UTR sequence variation remains open to speculation. Our study of the OPA3 gene in patients with 3MGA without Costeff syndrome suggests that mutations in OPA3 are not a common cause of 3MGA in the absence of signs of Costeff syndrome.

Abstract
UNLABELLED We report on a favourable case of MCAD deficiency (homozygous 985A > G) that presented as lethargy, poor feeding, pulmonary haemorrhage and cardiac arrest without hypoglycaemia. The cessation of intralipid and the commencement of carnitine supplementation were associated with a rapid clinical improvement. CONCLUSION Mild carnitine depletion and secondary impairment of long-chain fatty acid metabolism may have contributed to post-asphyxial myocardial dysfunction and ventricular arrhythmias. Metabolic disorders must be kept in mind as a differential diagnosis in acutely ill infants, but it must also be emphasized that carnitine therapy is not uniformly effective in all MCAD patients.

Abstract
BACKGROUND In-stent restenosis may be prevented by impregnating an antiproliferative agent in a polymer from a stent platform. This approach requires both an antiproliferative agent effective in small doses and a biocompatible polymer. METHODS A series of new biodegradable elastomeric poly(ester-amide)(co-PEA) polymers having functional carboxyl groups for drug conjugation were synthesized from non-toxic building blocks. The in-vivo biocompatibility was tested in porcine coronary arteries, by comparing the polymer-coated stents with bare metal stents in 10 pigs. RESULTS All animals survived until sacrifice 28 days later and follow-up angiography prior to sacrifice revealed identical diameter stenosis (21 +/- 23%) in both groups. Histology confirmed similar injury scores (0.34 +/- 0.34 compared with 0.34 +/- 0.32), inflammatory reaction (1.18 +/- 0.38 compared with 1.11 +/- 0.32) and area stenosis (26 +/- 17% compared with 28 +/- 22%). CONCLUSIONS This study suggests that the newly developed copoly(ester-amide) elastomers may be suitable for stent-based local drug delivery.

Abstract
Three patients with ketosis had increased excretion of 3-hydroxyglutarate (21.8-37.9 micromol/mmol creatinine; controls 2.3 +/- 1.6), an indicator of glutaryl-CoA dehydrogenase deficiency (GDHD), which normalized when the patients were nonketotic. Clinical assessment of all three patients and enzyme studies in one patient were not consistent with GDHD. These findings were compared with those of other ketotic patients, who showed statistically significant increases in 3-hydroxyglutarate excretion (9.4 +/- 5.0 micromol/mmol creatinine; p < 0.01), and with those of a child with confirmed GDHD when she was both ketotic and nonketotic. Secondary increase in 3-hydroxyglutarate excretion during ketosis is a potential confounder in the diagnosis of GDHD.

Abstract
The ovine genome contains 15 to 20 copies of endogenous retroviruses (enJSRVs) highly related to the oncogenic jaagsiekte sheep retrovirus (JSRV) and enzootic nasal tumor virus. enJSRVs are highly expressed in the endometrial lumenal epithelia (LE) and glandular epithelia (GE) of the ovine uterus. The effects of neonatal age, estrous cycle, pregnancy, and progesterone on expression of enJSRVs in the ovine uterus were determined. Expression of enJSRV RNAs was absent from the uterus of ewes at birth, but enJSRV RNAs were expressed specifically in the LE and developing GE from postnatal day (PND) 7 to PND 56. In adult ewes, enJSRV RNAs were detected only in the epithelia of the uterine endometrium, as well as epithelia of the oviduct, cervix, and vagina. In cyclic ewes, endometrial enJSRV RNA abundance was lowest on day 1, increased 12-fold between days 1 and 13, and then decreased to day 15. In pregnant ewes, levels of endometrial enJSRV RNAs were high on day 11, increased to day 13, and then decreased to day 19. In day 17 and 19 conceptuses, enJSRV RNAs were also detected in binucleate cells of the trophectoderm. Immunoreactive JSRV capsid and envelope proteins were detected in the endometrial LE and GE, as well as in the binucleate cells of the conceptus. In transfection assays utilizing ovine endometrial LE cells, progesterone increased transcriptional activity of several enJSRV long terminal repeats. Collectively, these results indicate that transcription of enJSRVs in the endometrial epithelia of the ovine uterus is increased by progesterone and might support a role for enJSRVs in conceptus-endometrium interactions during the peri-implantation period and early placental morphogenesis.

Abstract
OBJECTIVE To evaluate newborn screening by tandem mass spectrometry for detection of medium chain acyl-CoA dehydrogenase (MCAD) deficiency, a fatty acid oxidation disorder with significant mortality in undiagnosed patients. DESIGN The following were studied: (a) 13 clinically detected MCAD deficient subjects, most homozygous for the common A985G mutation, whose newborn screening sample was available; (b) 275 653 consecutive neonates undergoing routine newborn screening. Screened infants with blood octanoylcarnitine levels > or = 1 micromol/l were analysed for the A985G mutation, had analysis of plasma and repeat blood spot acylcarnitines and urinary organic acids, and had fibroblast fatty acid oxidation or acylcarnitine studies. RESULT Twelve of the 13 patients later diagnosed clinically had newborn octanoylcarnitine levels > 2.3 micromol/l. Twenty three screened babies had initial octanoylcarnitine levels > or = 1 micromol/l. Eleven of 12 babies with persistent abnormalities had metabolite and/or enzyme studies indicating MCAD deficiency. Only four were homozygous for the A985G mutation, the remainder carrying one copy. CONCLUSIONS Most patients with symptomatic MCAD deficiency could be detected by newborn screening. Infants actually detected had a lower frequency of A985G alleles than clinically diagnosed cases and may have a lower risk of becoming symptomatic.

Abstract
Limbic encephalitis (LE) is often associated with lung, thymic, or testicular tumours and antibodies to Hu, CV2, or Ma2 (Ta) antigens. In these cases, it generally has a poor prognosis. Here we describe two patients with symptoms of LE, negative for typical paraneoplastic antibodies, in whom antibodies to voltage-gated potassium channels (VGKC) were detected retrospectively in serial serum samples. Patient 1 had a thymoma recurrence, but in patient 2 no tumour has been detected in the years following presentation. Plasma exchange was effective in reducing VGKC antibody levels, with substantial improvement in mental symptoms in patient 1. In patient 2, the VGKC antibodies fell spontaneously over two years, with almost complete recovery of mental function. Although neither patient had obvious neuromyotonia at presentation, both showed excessive secretions. We suggest that patients with limbic symptoms and excessive secretions should be tested for VGKC antibodies, and, if they are present, prompt and effective immunosuppressive treatment should be considered.

Abstract
The carnitine transporter defect is a potentially fatal but treatable disorder. We used electrospray tandem mass spectrometry in the New South Wales (Australia) Newborn Screening Programme to measure free carnitine and acylcarnitine species in the newborn population. Free carnitine levels in dried blood samples from 149,000 neonates did not vary markedly between 2 and 8 days of age. Two of 4 babies subsequently diagnosed clinically with the carnitine transporter defect had a free carnitine level in the neonatal blood sample low enough to be detected by screening.

The free carnitine and acylcarnitine profile in dried whole blood filter paper samples collected at ages 1 and 4 days showed a markedly elevated concentration of free carnitine (141 and 142 micromol/L, respectively), normal concentrations of acetyl- and propionylcarnitine, with the near absence of all other species. The diagnosis was confirmed by in vitro fatty acid oxidation screening assays and enzyme assay in cultured skin fibroblasts. Retrospective study of the newborn whole blood sample of the index case showed a similar profile (free carnitine 181 micromol/L). The newborn population distribution of free carnitine (n = 143,981) showed that only three samples had free carnitine > 140 micromol/L (>99.9th centile), two were from L-CPT I-deficient neonates and one from a baby with sepsis. While there are other conditions that can cause elevated concentrations of free carnitine, an isolated elevation of free carnitine only in an apparently healthy term neonate warrants further investigation to exclude L-CPT I deficiency.

Abstract
Women who develop bilateral breast cancer at an early age are likely to harbour germline mutations in breast cancer susceptibility genes. The aim of this study was to test for concordant genetic changes in left and right breast cancer of young women (age < 50) with bilateral breast cancer that may suggest an inherited breast cancer predisposition. Microsatellite markers were used to test for loss of heterozygosity (LOH) in left and right tumours for 31 women with premenopausal bilateral breast cancer. Markers adjacent to or within candidate genes on 17p (p53), 17q (BRCA1), 13q (BRCA2), 11q (Ataxia Telangiectasia-ATM) and 3p (FHIT) were chosen. Mutational testing for BRCA1 and BRCA2 was performed for cases where blood was available. Concordant LOH in both left and right tumours was demonstrated for at least one of the markers tested in 16/31(54%) cases. Where allelic loss was demonstrated for both left and right breast cancer, the same allele was lost on each occasion. This may suggest a common mutational event. Four cases showed concordant loss of alleles in both left and right breast cancer at D17S791 (BRCA1). BRCA1 mutations were identified in two of these cases where blood was available. Four cases showed concordant LOH at D13S155 (BRCA2). Concordant LOH was further demonstrated in seven cases for D11S1778 (ATM) and four cases for D3S1300 (which maps to the FHIT gene), suggesting a possible role for these tumour suppressor genes in this subgroup of breast cancer patients. No concordant allelic loss was demonstrated for D17S786 suggesting that germline mutations in p53 are unlikely in such cases of bilateral breast cancer.

Abstract
ATP activates damage-sensing neurons (nociceptors) and can evoke a sensation of pain. The ATP receptor P2X3 is selectively expressed by nociceptors and is one of seven ATP-gated, cation-selective ion channels. Here we demonstrate that ablation of the P2X3 gene results in the loss of rapidly desensitizing ATP-gated cation currents in dorsal root ganglion neurons, and that the responses of nodose ganglion neurons to ATP show altered kinetics and pharmacology resulting from the loss of expression of P2X(2/3) heteromultimers. Null mutants have normal sensorimotor function. Behavioural responses to noxious mechanical and thermal stimuli are also normal, although formalin-induced pain behaviour is reduced. In contrast, deletion of the P2X3 receptor causes enhanced thermal hyperalgesia in chronic inflammation. Notably, although dorsal-horn neuronal responses to mechanical and noxious heat application are normal, P2X3-null mice are unable to code the intensity of non-noxious 'warming' stimuli.

Abstract
Whilst many reports mention neurofibrillary tangle pathology in the thalamus in progressive supranuclear palsy, there has been little detailed regional analysis of the distribution and density of thalamic pathology in this disease or in other parkinsonian syndromes. The caudal intralaminar thalamic nuclei are the major thalamic regulators of the caudate nucleus and putamen, areas known to be dysfunctional in progressive supranuclear palsy and Parkinson's disease. We investigated whether these thalamic nuclei degenerate in patients with these disorders compared with age-matched, neurologically normal controls. Neurofibrillary tangle and Lewy body pathology was assessed and unbiased optical disector methods were used to quantify total neuronal number. Despite different thalamic pathology, there was a dramatic reduction in the total neuronal number in the caudal intralaminar nuclei in both progressive supranuclear palsy and Parkinson's disease (40-55% loss). In contrast, there was no loss of volume or total neuronal number in the limbic thalamic nuclei in either disease group, indicating selective degeneration of the caudal intralaminar nuclei. In Parkinson's disease, Lewy bodies were found in these regions, while in progressive supranuclear palsy abundant intracellular neurofibrillary tangles and glial tangles concentrated in the caudal intralaminar nuclei. However, tangle formation accounted for only a small proportion of cell loss (</=10%) in the thalamus in progressive supranuclear palsy. These findings have several implications. The caudal intralaminar thalamus appears to be one of three basal ganglia sites commonly affected in both progressive supranuclear palsy and Parkinson's disease. These sites are the dopaminergic substantia nigra, the cholinergic pedunculopontine tegmental nucleus and, from our results, the glutamatergic caudal intralaminar thalamus. In both diseases these sites contain characteristic but different pathologies, indicating disease-specific mechanisms of neurodegeneration. Interestingly, the proportion of remaining neurons affected by these pathologies is low. This may indicate additional (possibly common) cellular mechanisms responsible for the degeneration in these regions. Both the dopaminergic nigra and the glutamatergic caudal intralaminar thalamus are the major regulators of basal ganglia function via the caudate nucleus and putamen. The pedunculopontine tegmental nucleus has major projections to both of these regulators. These findings indicate that dysregulation of two neurotransmitter systems within the basal ganglia may underlie common parkinsonian symptoms in these disorders. For patients with Parkinson's disease, this loss of glutamate regulation may help explain some problems with dopamine replacement therapies, particularly over time. For patients with progressive supranuclear palsy, more widespread degeneration of basal ganglia structures would contribute to poor treatment outcomes.

Abstract
A series of twelve cases, all of whom had received surgery for the removal of a colloid cyst in the third ventricle, was examined on a series of memory tests. The only consistent predictor of poor memory performance that could be detected from MRIs was the presence of bilateral interruption of the fornix, which occurred in three of the subjects. Although these three cases were poor on tests of learning and recall, there was evidence that recognition was less impaired. The subjects were also tested on a set of recognition and concurrent discriminations that closely matched tests given to non-human primates. Clear parallels were found between the apparent effects of fornix damage in these clinical cases and those observed following more selective surgery in non-human primates. These findings not only indicate that fornix damage is sufficient to induce anterograde amnesia but also support the validity of recent animal tests that are thought to capture aspects of episodic memory.

Abstract
Two major noncortical inputs to the striatum originate from the substantia nigra and the thalamic centré median-parafascicular complex. Although it is established that in Parkinson's disease there is degeneration of the nigral dopaminergic neurons, there has been little analysis of the glutamatergic centré median-parafascicular complex. We therefore evaluated these and neighboring thalamic nuclei (for specificity of any changes) in 9 Parkinson's disease patients and 8 age-matched controls. Degeneration in the substantia nigra and centré median-parafascicular complex was estimated by using quantitative neuronal counts. On average, 70% of the pigmented nigral neurons degenerated and there was 30% to 40% neuronal loss in the centré median-parafascicular complex in Parkinson's disease. Thalamic degeneration was marked in neuronal subpopulations (50% loss of parvalbumin-positive neurons in the parafascicular, and 70% loss of non-parvalbumin-positive neurons in the centré median nuclei). In contrast, adjacent thalamic nuclei did not degenerate, which supports a selective neurodegeneration of the centré median-parafascicular complex. Our results show that the thalamic centré median-parafascicular complex is an additional nondopaminergic site of neurodegeneration in Parkinson's disease. Because this thalamic region provides important sensorimotor feedback to the striatum, degeneration of this region is likely to exacerbate the clinical signs and symptoms of Parkinson's disease.

Abstract
Since 1998, the NSW Newborn Screening Program has used electrospray tandem mass spectrometry (MS/MS) to analyse samples from all babies born in NSW and the ACT (approximately 95000 per year) for selected amino acids and acylcarnitines. The software rules editor initially interprets all results where ratio of analyte to internal standard is modified by input from the external standard curves per analyte. The numerical results are then downloaded to the NSW Newborn Screening database, which provides automatic, analyte specific follow-up test cascade. We have analysed samples from 137 120 consecutive newborns received by the program, requested repeat samples from 122 babies, and found abnormal levels in 17 babies with phenylketonuria, 1 tetrahydrobiopterin deficiency, 3 hyperphenylalaninaemia, 1 maple syrup urine disease, 1 tyrosinaemia type II, 1 congenital lactic acidosis, 2 medium-chain acyl CoA dehydrogenase deficiency, 1 short-chain acyl CoA dehydrogenase deficiency, 1 beta-ketothiolase deficiency, 2 vitamin B12 deficient babies of vegan mothers and 1 glutaric aciduria type I. Using population data plus that obtained from retrospective samples with proven disorders we have established cut-off levels for each analyte tested. This coupled with the ability of the database to provide ratios of various analytes gives excellent screening specificity and sensitivity for the detection of at least 40 rare inborn errors of metabolism.
