Abstract
Pediatric bipolar disorder (PBD) is a complex illness with a chronic course, requiring multiple medications over the longitudinal course of illness, with limited recovery and high relapse rate. Beyond the placebo controlled trials of monotherapy, there is an increased need to understand how each medication influences regions of affective and cognitive circuitry function by normalization or deployment of alternative circuitry regions. Functional studies are beginning to unravel the improved function in the fronto-limbic and fronto-temporal affective circuitry, and based on the paradigm administered, also in the interfacing cognitive fronto-striato-temporo-parietal regions. Treatment studies illustrated a pattern of improvement in functional activity consistently among the affective ventrolateral and medial prefrontal regions, and variably in the cognitive dorsolateral prefrontal cortex. While there is decreased activity in amygdala with treatment for mania or depression among patients with PBD, there appears to be residual increased amygdala activity regardless of response, relative to healthy controls, suggesting a trait-like abnormality. Parallel biochemical abnormalities in magnetic resonance spectroscopic studies and fronto-limbic activity in magnetic resonance imaging studies of brain function at baseline provide maiden data on predicting outcome. This preliminary cohort of studies that probed the hypothesized circuitries underlying specific symptom constructs, coupled with futuristic paradigms and analytic methods, serve as a guidepost to generate the next generation of studies and build on the emerging biosignature towards specific treatment targets for personalized medicine in PBD.

Abstract
OBJECTIVES To develop a simplified true/false response format of the Revised Diabetes Knowledge Scale and assess scaling assumptions, reliability and validity of the binary response format (the Simplified Diabetes Knowledge Scale) and compare with a multiple-choice version. METHODS Ninety-nine respondents attending an outpatient clinic completed the multiple-choice version of the Revised Diabetes Knowledge Scale and the simplified version of the Revised Diabetes Knowledge Scale. The response patterns and psychometric properties of both questionnaires were assessed in order to test the construct validity of the simplified version. RESULTS The mean age of the respondents was 57 years (range 21-83 years) and 64% were men. Respondents attained an average score of 65% on the Simplified Diabetes Knowledge Scale, compared with 62% on the Revised Diabetes Knowledge Scale. Overall, the Simplified Diabetes Knowledge Scale appeared to be somewhat easier to complete compared with the Revised Diabetes Knowledge Scale, as indicated by the number of missing responses. CONCLUSIONS The Simplified Diabetes Knowledge Scale provides researchers with a brief and simple diabetes knowledge questionnaire with favourable psychometric properties. The scale may require further updating to include other items relevant to diabetes education. This simplified version will now undergo translation and validation for use among minority ethnic groups resident in the UK.

Abstract
ABSTRACTA series of PtSi on p-type Si diodes have been characterized in order to establish correlations among processing parameters, metallurgical features and electrical properties. Characterization techniques include analytical (TED, TEM), electrical (current-voltage characteristics), and optical (photoemission and absorption). The fabrication techniques involve e-beam evaporation of platinum layers at UHV levels onto VLSI grade (100) p-type silicon substrates. The silicide layers are formed via sub-eutectic solid state diffusion at 350°C. The main trends with thickness as well as possible interrelationships are described. An unexpected result is the presence of unreacted polycrystalline Pt and Pt2Si at the interface.

Abstract
The majority of triplet and higher order multiple pregnancies now result from ovulation induction/superovulation rather than in vitro fertilisation. However, clomiphene citrate is still widely prescribed by gynaecologists and general practitioners who do not have access to ultrasound monitoring. The objective of our study was to determine the prevalence of multifollicular development with different doses of clomiphene citrate. A retrospective review of transvaginal ultrasound monitoring of 425 cycles in 182 women receiving clomiphene citrate from January 2002 to December 2003, was studied. Three or more follicles of >or= 14 mm were identified in 58 cycles (14%). Patients received 50 mg of clomiphene citrate in 52 of these 58 cycles and 25 mg in the remaining six. One patient was noted to have developed five follicles and 10 patients developed four follicles. One patient developed six follicles, despite receiving only 25 mg clomiphene citrate daily. It was concluded that a significant number of women (14%) developed three or more follicles, despite receiving low doses of clomiphene citrate.

Abstract
In this paper we present a review of practices surrounding the consumption of khat (Catha edulis) within recent migrant communities in Melbourne from East Africa. Cultures in East Africa and the Arabian Peninsular have used khat as a stimulant since the seventh century and the practice of coming together to chew the leaves of the khat plant has acquired unique cultural importance. Based on focus-group interviews the research examines transformations taking place in the meaning of khat for East African communities within their experiences of displacement and considers how the arrival of khat might be managed in the Australian context. Emphasis is given to indigenous models and the cultural context of practices surrounding khat. This anthropology of khat use in Melbourne summarizes issues such as who chews it, traditional settings for khat gatherings, culturally defined effects of the leaf, health effects, beliefs and attitudes, levels of use, gendered attitudes and questions of dependence. These issues raise questions regarding the reception of indigenous substance use within a state that claims to be multicultural.

Abstract
OBJECTIVE A major clinical problem in Orthopaedics is the repair of traumatic articular cartilage lesions. The MRL/MpJ strain of mice has the remarkable ability to regenerate ear hole punch wounds seamlessly including the scarless replacement of multiple tissues. The objective of this study was to assess whether articular cartilage defects repair or regenerate in the MRL/MpJ 'healer' strain of mice. METHOD Full thickness and partial thickness lesions were introduced into trochlear groove articular cartilage of MRL/MpJ and C57Bl/6 mice, a control strain that does not undergo ear hole regeneration. The wound sites were assessed 6 weeks and 12 weeks post-surgery using a histological scoring scheme and immunohistochemistry for markers of articular cartilage including proteoglycan, collagen II and collagen VI. RESULTS The partial thickness lesions did not repair in either strain. However, at both 6 weeks and 12 weeks timepoints the MRL/MpJ mice had a superior healing response of full thickness lesions with abundant chondrocytes and an extracellular matrix rich in proteoglycan, collagen II and collagen VI at the wound site. At the 12 week timepoint the enhanced cartilage healing was restricted to male MRL/MpJ mice. In contrast, the C57Bl/6 control strain produced an extracellular matrix at the wound site that, overall, had significantly less matrix proteoglycan and collagen II. CONCLUSIONS Male MRL/MpJ mice appear to possess an intrinsic ability to 'regenerate' articular cartilage. Understanding the biochemical and genetic basis for articular cartilage regeneration may open up new treatment options for traumatic articular cartilage defects.

Abstract
The subject of central nervous system damage includes a wide variety of problems, from the slow selective 'picking off' of characteristic sub-populations of neurons typical of neurodegenerative diseases, to the wholesale destruction of areas of brain and spinal cord seen in traumatic injury and stroke. Experimental repair strategies are diverse and the type of pathology dictates which approach will be appropriate. Damage may be to grey matter (loss of neurons), white matter (cutting of axons, leaving neurons otherwise intact, at least initially) or both. This review will consider four possible forms of treatment for repair of the human central nervous system.

Abstract
13547 Background: We previously reported the combination of preoperative radiation (RT) with concurrent Irinotecan and 5-FU in locally advanced rectal cancer, was well tolerated and had an excellent pathologic complete response rate (CR) of 25%, but with catheter related infections and thromboses as major toxicities (Proc Am Soc Clin Onc 22: 2003). With the potential benefits of capecitabine (Cap) and no need for an implanted catheter, a phase I study was initiated to determine the toxicity and maximum tolerated dose (MTD) of Cap with concurrent Ir and RT. Methods: Eligible patients (pts) had primary or recurrent Stage II or III rectal adenocarcinoma, without a history of prior RT or chemotherapy. The treatment regimen was as follows: external beam RT at 1.8Gy daily M-F, to a total dose of 50.4 or 54 Gy; Ir 50 mg/m2 IV, d 1, 8, 15, 22; dose escalating Cap starting at 825 mg/m2 PO divided in 2 doses, Q 12h. Surgical resection occurred at 6–10 weeks. Dose limiting toxicity is defined as Gr4 heme or non-heme Gr3. Results: A total of 16 pts have enrolled on the study, 10 male and 6 female;the median age was 57 (range 44–77). All are evaluable for toxicity. The Table reviews the maximum toxicities. Grade three diarrhea is the only dose-limiting toxicity to date. There has also been 3 pts with Gr 3 hematologic toxicity. There has been no Gr 4 toxicity. Patients are currently accruing on the 4th dose level of capecitabine. A total of 13 pts have completed the preoperative phase and three are currently on treatment. Eleven pts have had surgical resection. One pt refused surgery due to a biopsy proven CR to chemoradiation. One pt refused surgery and died of disease. Of the 11 pts undergoing surgical resection, there have been 3 pathologic CR. Conclusions: The preoperative combination of capecitabine, irinotecan and radiation in locally advanced rectal cancer pts is feasible and well tolerated. The study continues to accrue, and the MTD has not been achieved. [Table: see text] [Table: see text]

Abstract
Subjective tinnitus (heard only by the patient) is a common otological complaint. Objective tinnitus (heard by the examiner as well as the patient) is extremely rare. There are only a few cases of objective tinnitus, secondary to middle-ear myoclonus, described in the literature.We present the case of a child with bilateral, congenital, objective tinnitus, secondary to middle-ear myoclonus, with otherwise normal hearing thresholds (250Hz-8kHz), and with no evidence of intra-cerebral or systemic disorders. No similar case has been reported in the world literature.

Abstract
Clinical MR systems operating at 3.0 Tesla have the potential to significantly improve spatial resolution due to the boost in intrinsic signal to noise ratio. However, body imaging at these field strengths presents a number of technical challenges. We performed a prospective pilot study in which 10 patients underwent an MR cholangiopancreatography (MRCP) examination consecutively on 1.5 and 3.0 Tesla systems (both Philips Intera). An axial half Fourier segmented turbo spin echo (HASTE) sequence and a coronal thick-slab 2D turbo-spin echo (TSE) sequence were compared on both systems. A reader measured the signal intensity (SI) ratios of common bile duct (CBD): liver, and CBD: fat on HASTE images and CBD: liver on the TSE images. A second reader performed a qualitative analysis of the intrahepatic and extrahepatic biliary anatomy. Quantitative data was compared using the paired t-test and qualitative data with the paired Wilcoxon signed rank test with p < 0.05. The quantitative analysis of the HASTE sequences showed a slightly higher signal intensity ratio (CBD:liver) at 3.0 Tesla compared with 1.5 Tesla (8.1 vs 5.6, p = 0.002). No significant difference was found between the SI ratios of (CBD:fat) on HASTE images or (CBD:liver) on TSE images. The qualitative analysis showed superior image quality of 3.0 Tesla over 1.5 Tesla images on both HASTE (31 vs 25, p = 0.032), and TSE sequences (34 vs 28, p = 0.043). This pilot study shows that MRCP is feasible at 3.0 Tesla with some improvement in image quality and signal characteristics. Further development may be achieved with sequence optimization and improved coil design.

Abstract
This article aims to raise awareness among paediatricians and specialist paediatric services that poor oral health, in particular children with chronic illness, is a major cause of morbidity and can be a risk factor for severe, even life threatening complications. Good oral health and dentition is important for efficient mastication, speaking and of course, cosmetically for smiling. If left untreated, dental caries can lead to pain and infection. Chronic infection around one or more teeth can result in damage to localised structures, such as the developing permanent teeth. Children who are medically compromised (such as being immunocompromised from disease and/or therapy) however are at increased risk of developing systemic complications from dental infections, which may prove fatal. We focus on the role of the general paediatrician in promoting the importance of good dental health for all children and in particular those children "at risk". We present preventive measures, evidence based where available, that may improve dental care and promote the role of paediatric dental services in the multidisciplinary management of chronic disease.
