Abstract
BACKGROUND Paediatric acquired brain injury is a life-long condition which impacts on all facets of the individual's lived experience. The existing evidence base continues to expand and new fields of enquiry are established as clinicians and researchers uncover the extent of these impacts. PRIMARY OBJECTIVE To add to recommendations described in the International Paediatric Brain Injury Society's 2016 paper on post-acute care for children with acquired brain injury and highlight new areas of enquiry. REVIEW OF INFORMATION Recommendations were made based on the opinions of a group of experienced international clinicians and researchers who are current or past members of the board of directors of the International Paediatric Brain Injury Society. The importance of each recommendation was agreed upon by means of group consensus. OUTCOMES This update gives new consideration to areas of study including injuries which occur in pre-school children, young people in the military, medical referral, young offenders and the use of technology in rehabilitation.

Abstract
Abstract
Introduction
The NHS Long Term Plan aims to ‘prevent up to 150,000 heart attacks, strokes and dementia cases over the next 10 years’.1 People with Familial Hypercholesterolaemia (FH) are considered to be at high-risk of heart attack, stroke and dementia but an estimated 90% remain undiagnosed.1 The Chesterfield and Dronfield Primary Care Network were commissioned to set-up a 12-month pharmacist-led clinic across 9 practices to identify, treat and refer FH patients. Patients with suspected FH benefit from referral to specialist services.2
Aim
This study aimed to evaluate the number of FH patients identified and any unintended benefits of the Lipid Clinic.
Methods
Ethical approval was not required for this service evaluation. Informed consent was sought prior to data collection and the dataset was anonymised. Searches of practice patient records identified patients with a previously raised lipid level (total Cholesterol >7.5mmol/L and/or non-HDL-C > 5.9mmol/L)2 for review in the Lipid Clinic. Patients reviewed in the Lipid Clinic were initiated/optimised on lipid lowering medication as appropriate.2 Data were collected for patients invited for review in the Lipid Clinic between May-July 2022. Patients’ attendance as well as decline/non-response to the Clinic was recorded. The data collected included family history, QRISK score (where applicable), lipid lowering treatment the patient was taking (if any) and blood tests results (serum lipids, HBA1c and thyroid function tests). If bloods were deranged it was documented whether or not it was a new finding. The data was analysed by categorising patients into potential FH, primary/secondary prevention of cardiovascular disease and whether they needed referral to secondary care.
Results
Out of the 260 patients invited for review, 219 attended the clinic. Of these, 30 (13.7%) were provided with lifestyle advice as they did not meet the criteria for treatment. Twenty-three patients (10.5%) met the Simon-Broom criteria for possible FH. A further 3 patients identified were known to have FH but had not undergone genetic cascade testing. These 26 patients (11.8%) were referred to secondary care for genetic testing and specialist input. Newly raised HbA1c indicative of either diabetes or non-diabetic hyperglycaemia was incidentally found in 39 patients (17.8%). Lipid-lowering medication was initiated/titrated in 189 patients (86.3%).
Discussion/Conclusion
The significant proportion of patients requiring follow up in secondary care (11.8%) suggesting targeted searches are effective in identifying patients with possible FH. Identifying FH patients, testing and treating their family members appropriately reduces their risk of cardiovascular events.2 The Lipid Clinic has identifying that nearly a fifth of patients were previously undiagnosed with either diabetes or non-diabetic hyperglycaemia (17.8%) suggests that this is also an opportunity to identify and treat these patients earlier than they would otherwise have been identified. The results highlight the need for primary care staff education on the new AAC NHS Guidelines2 relating to managing lipid results. One limitation of the study is although the Lipid Clinic has received good informal feedback, formal feedback is yet to be collected from patients and stake holders. In addition, the clinic is still ongoing, and more data is being collected.

Abstract
OBJECTIVES Primary: describe characteristics of adults aged ≥65 attending the Emergency Department (ED) at one major trauma center. Secondary: examine co-morbidities and complications; identify use of anticoagulant/antiplatelet medication among older adults presenting with Head Injury (HI); assess clinical management against UK guidelines. METHODS All ED admissions were screened prospectively to identify HI using case notes, hospital records and Trauma Audit Research Network data. Data were collected on demographics, cause and severity of injury, co-morbidities, anticoagulation/antiplatelet use, diagnostic imaging and discharge outcomes. RESULTS Over 12 months, 697 patients aged ≥65 years attended the ED for HI, representing over a quarter of adult ED attendances for HI. Mean age was 78.5 years (range 65-106), 395 (56.7%) were female. Most HIs were mild (93.5%) and 86% caused by falls. Three-quarters were discharged without hospital admission. Most had a preexisting medical condition andtaking medications prior to HI. Of these 116 were taking anticoagulants/antiplatelets but only 37 (31.9%) received a head CT scan. Half the patients were given a written HI information sheet at ED discharge. CONCLUSIONS Care of HI in older adults is challenging due to comorbidities. Practising evidence-based clinical management and following guidelines is important, but strict adherence is not common practice.

Abstract
OBJECTIVES Our aim was to determine the incidence of traumatic brain injury (TBI) in older adults and investigate the relationship between injury characteristics and outcomes. METHODS Retrospective analysis of prospectively collected data submitted to Trauma Audit and Research Network (TARN) database for a major trauma centre in the West Midlands, UK, from 2008 to 2014. The Mayo Scale was used to categorise TBI. All patients were aged ≥65 years and were admitted with head or brain injuries meeting TARN inclusion criteria: injury resulting in immediate admission to hospital for 3 days, admitted to a high dependency area or death following trauma. We determined age, gender, mechanism of injury, Injury Severity Score, presenting Glasgow Coma Scale (GCS) and Mayo Score, and the association of outcome (Glasgow Outcome Scale (GOS)) with age and clinical presentation. RESULTS 4413 patients were admitted with trauma meeting TARN criteria: 1389 were ≥65 years and 45% (624) had TBI. For patients ≥65 years with TBI, mean age was 79 (range 65-99); 56% were men. Falls accounted for 85% of all TBIs. Most TBIs were moderate/severe (80%) by the Mayo criteria. Of the 279 patients with subdural haematoma, 28% had neurosurgery. Most patients survived TBI (78%); 57% had a good outcome on GOS at discharge (not requiring care package). Mortality was associated with increased age (17% in ages 65-74 years, 19% in 75-84 years, 30% in ≥85 years, p=0.03). Outcome was significantly associated with injury severity (p=0.0001). CONCLUSIONS Patients with TBI represented 45% of all trauma cases meeting TARN inclusion criteria. Falls at home accounted for most TBIs. Most had moderate/severe TBI, yet over half made a good recovery on GOS. Our data indicate that injury prevention initiatives should focus on home safety. Further research is needed to examine rehabilitation and follow-up after hospital discharge.

Abstract
BACKGROUND The use of technology in healthcare settings is on the increase and may represent a cost-effective means of delivering rehabilitation. Reductions in treatment time, and delivery in the home, are also thought to be benefits of this approach. Children and adolescents with brain injury often experience deficits in memory and executive functioning that can negatively affect their school work, social lives, and future occupations. Effective interventions that can be delivered at home, without the need for high-cost clinical involvement, could provide a means to address a current lack of provision.We have systematically reviewed studies examining the effects of technology-based interventions for the rehabilitation of deficits in memory and executive functioning in children and adolescents with acquired brain injury. OBJECTIVES To assess the effects of technology-based interventions compared to placebo intervention, no treatment, or other types of intervention, on the executive functioning and memory of children and adolescents with acquired brain injury. SEARCH METHODS We ran the search on the 30 September 2015. We searched the Cochrane Injuries Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), Ovid MEDLINE(R), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid OLDMEDLINE(R), EMBASE Classic + EMBASE (OvidSP), ISI Web of Science (SCI-EXPANDED, SSCI, CPCI-S, and CPSI-SSH), CINAHL Plus (EBSCO), two other databases, and clinical trials registers. We also searched the internet, screened reference lists, and contacted authors of included studies. SELECTION CRITERIA Randomised controlled trials comparing the use of a technological aid for the rehabilitation of children and adolescents with memory or executive-functioning deficits with placebo, no treatment, or another intervention. DATA COLLECTION AND ANALYSIS Two review authors independently reviewed titles and abstracts identified by the search strategy. Following retrieval of full-text manuscripts, two review authors independently performed data extraction and assessed the risk of bias. MAIN RESULTS Four studies (involving 206 participants) met the inclusion criteria for this review.Three studies, involving 194 participants, assessed the effects of online interventions to target executive functioning (that is monitoring and changing behaviour, problem solving, planning, etc.). These studies, which were all conducted by the same research team, compared online interventions against a 'placebo' (participants were given internet resources on brain injury). The interventions were delivered in the family home with additional support or training, or both, from a psychologist or doctoral student. The fourth study investigated the use of a computer program to target memory in addition to components of executive functioning (that is attention, organisation, and problem solving). No information on the study setting was provided, however a speech-language pathologist, teacher, or occupational therapist accompanied participants.Two studies assessed adolescents and young adults with mild to severe traumatic brain injury (TBI), while the remaining two studies assessed children and adolescents with moderate to severe TBI. Risk of biasWe assessed the risk of selection bias as low for three studies and unclear for one study. Allocation bias was high in two studies, unclear in one study, and low in one study. Only one study (n = 120) was able to conceal allocation from participants, therefore overall selection bias was assessed as high.One study took steps to conceal assessors from allocation (low risk of detection bias), while the other three did not do so (high risk of detection bias). Primary outcome 1: Executive functioning: Technology-based intervention versus placeboResults from meta-analysis of three studies (n = 194) comparing online interventions with a placebo for children and adolescents with TBI, favoured the intervention immediately post-treatment (standardised mean difference (SMD) -0.37, 95% confidence interval (CI) -0.66 to -0.09; P = 0.62; I(2) = 0%). (As there is no 'gold standard' measure in the field, we have not translated the SMD back to any particular scale.) This result is thought to represent only a small to medium effect size (using Cohen's rule of thumb, where 0.2 is a small effect, 0.5 a medium one, and 0.8 or above is a large effect); this is unlikely to have a clinically important effect on the participant.The fourth study (n = 12) reported differences between the intervention and control groups on problem solving (an important component of executive functioning). No means or standard deviations were presented for this outcome, therefore an effect size could not be calculated.The quality of evidence for this outcome according to GRADE was very low. This means future research is highly likely to change the estimate of effect. Primary outcome 2: MemoryOne small study (n = 12) reported a statistically significant difference in improvement in sentence recall between the intervention and control group following an eight-week remediation programme. No means or standard deviations were presented for this outcome, therefore an effect size could not be calculated. Secondary outcomesTwo studies (n = 158) reported on anxiety/depression as measured by the Child Behavior Checklist (CBCL) and were included in a meta-analysis. We found no evidence of an effect with the intervention (mean difference -5.59, 95% CI -11.46 to 0.28; I(2) = 53%). The GRADE quality of evidence for this outcome was very low, meaning future research is likely to change the estimate of effect.A single study sought to record adverse events and reported none. Two studies reported on use of the intervention (range 0 to 13 and 1 to 24 sessions). One study reported on social functioning/social competence and found no effect. The included studies reported no data for other secondary outcomes (that is quality of life and academic achievement). AUTHORS' CONCLUSIONS This review provides low-quality evidence for the use of technology-based interventions in the rehabilitation of executive functions and memory for children and adolescents with TBI. As all of the included studies contained relatively small numbers of participants (12 to 120), our findings should be interpreted with caution. The involvement of a clinician or therapist, rather than use of the technology, may have led to the success of these interventions. Future research should seek to replicate these findings with larger samples, in other regions, using ecologically valid outcome measures, and reduced clinician involvement.

Abstract
BACKGROUND AND AIMS There is a growing body of evidence supporting the nephrovascular toxicity of indoxyl sulphate (IS) and p-cresyl sulphate (PCS). Nonetheless, a comprehensive description of how these toxins accumulate over the course of chronic kidney disease (CKD) is lacking. METHODS AND RESULTS This cross-sectional observational study included a convenience sample of 327 participants with kidney function categorised as normal, non-dialysis CKD and end-stage kidney disease (ESKD). Participants underwent measurements of serum total and free IS and PCS and assessment of cardiovascular history and structure (carotid intima-media thickness [cIMT, a measure of arterial stiffness]), and endothelial function (brachial artery reactivity [flow-mediated dilation (BAR-FMD); glyceryl trinitrate (BAR-GTN)]). Across the CKD spectrum there was a significant increase in both total and free IS and PCS and their free fractions, with the highest levels observed in the ESKD population. Within each CKD stage, concentrations of PCS, total and free, were significantly greater than IS (all p < 0.01). Both IS and PCS, free and total, were correlated with BAR-GTN (ranging from r = -0.33 to -0.44) and cIMT (r = 0.19 to 0.21), even after adjusting for traditional risk factors (all p < 0.01). Further, all toxins were independently associated with the presence of cardiovascular disease (all p < 0.02). CONCLUSION More advanced stages of CKD are associated with progressive increases in total and free serum IS and PCS, as well as increases in their free fractions. Total and free serum IS and PCS were independently associated with structural and functional markers of cardiovascular disease. Studies of therapeutic interventions targeting these uraemic toxins are warranted.

Abstract
BACKGROUND Head injury (HI) is a common presentation to Child Emergency Departments (CEDs), but the actual number of children attending with minor HI is unclear. Most research has focussed on admitted patients, often relying on hospital-coded admission data. We studied the incidence of minor HI presenting to the CED of a major teaching hospital in Coventry and Warwickshire. HI attendances were compared with population data to identify injury patterns relating to deprivation. METHODS All CED admissions were screened by the research team, and data on minor head injuries (GCS 13-15) collected prospectively from 1st January until 31st August 2011. Information was collected on demographics, ethnicity, cause and severity of injury, injury location (in or outside the home), other injuries and mode of arrival. Deprivation data were obtained by cross-referencing postcodes with English Indices of Multiple Deprivation (IMD 2010). For comparison, the hospital audit department provided figures for coded head injuries during the same period. RESULTS During the 8 month period, hand-searching identified 1747 children with minor HI, aged between 0 and 16 years. Of these 99% had minimal HI (GCS 15 or 'alert'). In the same period, hospital-coded minor HIs numbered only 1081. HIs formed 9% of all CED attendances. Thirteen children returned to the CED with worrying symptoms after discharge home. Approximately 3.4% of the local paediatric population attend the CED with HI per year (3419/100,000 population). Falls accounted for 62% of HIs overall, rising to 77% in children aged 0-5. Most in-home head injuries (81%) were the result of falls (p<0.0001). Significantly more injuries took place inside the home for 0-5 year olds (58%) than for older children (20%) (p<0.0001). Children living in the most deprived areas were more likely to attend the CED with HI (RR: 1.19; CI: 1.06-1.35, p=0.004), and arrive using emergency services (OR: 1.77; CI: 1.30-2.40, p<0.001). There were no significant differences between the deprived and non-deprived groups for location or cause of injury. CONCLUSIONS Young children are particularly at risk of HI and parents should be offered information on injury prevention. More children from deprived areas attended with HI and these families may benefit most from targeted interventions.

Abstract
Introduction: The development of self-awareness across childhood is a complex and protracted phenomenon. Little is known about the consequences of an interruption to development as a result of a traumatic brain injury in childhood. The aim of this paper was to review the available literature on self-awareness in children following a traumatic brain injury and relate the findings to occupational therapy practice with this group of children and young people. Method: A comprehensive search of the current literature relating to self-awareness following a traumatic brain injury. Findings: A small amount of theoretical and qualitative literature was sourced and critically appraised using appropriate tools. Although only nine relevant papers were identified, those that were evaluated were found to be of a high quality. The findings were supplemented with additional material from developmental psychology and adult brain injury literature. Conclusion: Occupational therapists are encouraged to conceptualise self-awareness in childhood traumatic brain injury within a developmental context. A fuller understanding of self-awareness in childhood and the consequences of an interruption to its development will help to establish age-appropriate interventions.

Abstract
Head injury accounts for up to 20 per cent of emergency department (ED) attendances (Kay and Teasdale 2001), and approximately 800,000 patients attend U.K. EDs with head injuries every year (National Institute for Health and Clinical Excellence (NICE) 2007a, Scottish Intercollegiate Guidelines Network (SIGN) 2009). About 90 per cent of these patients have a mild or minor head injury and are managed in EDs before being discharged home (Swann and Teasdale 1999). NICE in England and Wales and SIGN in Scotland have issued guidelines for the early management of head injury in adults in an attempt to improve clinical practice. This article discusses the important role of emergency nurses, particularly with regard to discharge information and advice for patients, relatives and carers.

Abstract
In the UK, about 260,000 children with head injuries attend emergency departments each year (National Institute for Health and Clinical Excellence (NICE) 2007, Scottish Intercollegiate Guidelines Network (SIGN) 2009). About 90 per cent of these injuries are minor and can be managed without admission to hospital (Swann and Teasdale 1999). Clinical guidelines for early management of head injury have recently been published by NICE in England and Wales, and by SIGN in Scotland, to standardise management across the UK. This article discusses the role of emergency nurses in implementing these guidelines.

Abstract
A problem in clinical trials for antidepressants is that patient rating scales are not always completed properly. If one or more items are missing, a patient evaluation may be prevented from contributing towards an efficacy analysis. This can be very wasteful, particularly if data are missing at a baseline evaluation. In this study, we present a novel approach to estimating missing item scores on both the Montgomery-Asberg Depression Rating Scale and the Beck Depression Inventory. Our approach works on the assumption that patient response is non-uniform across items. By capturing the average between-item variation, we have developed a set of weights for each scale which can be used to predict missing item scores with high levels of accuracy. These weights were tested on several sets of patient data when one item was missing. The proposed weights are stable and will be of practical use to researchers in the field of Major Depression.

Abstract
Although immunosuppressive regimens are effective, rejection occurs in up to 50% of patients after orthotopic liver transplantation (OLT), and there is concern about side effects from long-term therapy. Knowledge of clinical and immunogenetic variables may allow tailoring of immunosuppressive therapy to patients according to their potential risks. We studied the association between transforming growth factor-beta, interleukin-10, and tumor necrosis factor alpha (TNF-alpha) gene polymorphisms and graft rejection and renal impairment in 121 white liver transplant recipients. Clinical variables were collected retrospectively, and creatinine clearance was estimated using the formula of Cockcroft and Gault. Biallelic polymorphisms were detected using polymerase chain reaction-based methods. Thirty-seven of 121 patients (30.6%) developed at least 1 episode of rejection. Multivariate analysis showed that Child-Pugh score (P =.001), immune-mediated liver disease (P =.018), normal pre-OLT creatinine clearance (P =.037), and fewer HLA class 1 mismatches (P =.038) were independently associated with rejection. Renal impairment occurred in 80% of patients and was moderate or severe in 39%. Clinical variables independently associated with renal impairment were female sex (P =.001), pre-OLT renal dysfunction (P =.0001), and a diagnosis of viral hepatitis (P =.0008). There was a significant difference in the frequency of TNF-alpha-308 alleles among the primary liver diseases. After adjustment for potential confounders and a Bonferroni correction, the association between the TNF-alpha-308 polymorphism and graft rejection approached significance (P =.06). Recipient cytokine genotypes do not have a major independent role in graft rejection or renal impairment after OLT. Additional studies of immunogenetic factors require analysis of large numbers of patients with appropriate phenotypic information to avoid population stratification, which may lead to inappropriate conclusions.

Abstract
Fibromuscular dysplasia (FMD) is an important cause of renal artery stenosis, particularly in young females. Polymorphisms of the renin-angiotensin (RA) system have been implicated in the pathogenesis of hypertension and atherosclerotic vascular disease, and may play a role in the development of FMD. Examination of polymorphisms by PCR for angiotensin-converting enzyme (ACE) I/D, angiotensin II type 1 receptor (AT1R) A1166C and angiotensinogen (AGT) M235T and T174M was undertaken in 43 patients with typical multifocal renal arterial FMD (MF-FMD) and in 89 controls. The age of MF-FMD patients at the time of diagnosis of hypertension did not differ (38.6 + 11.1 years vs 35.5 +/- 10.3 years, P = 0.12) from controls and the proportion (95% vs 86%, P = 0.14) of females was similar. Allele frequencies did not differ significantly between groups, except that MF-FMD patients had a significantly higher frequency of the ACE I allele than control subjects (0.62 vs 0.47, P = 0.026). Since the ACE I allele is associated with lower circulating ACE levels and possibly lower tissue levels of angiotensin II (Ang II), and since Ang II modulates vascular smooth muscle cell growth and synthetic activity, the I allele might predispose to defective remodelling of the arterial media, and thus to the development of MF-FMD. This contrasts with atherosclerotic renal artery stenosis, coronary stent restenosis and carotid intimal thickening, which are diseases affecting the arterial intima, and which are associated with increased frequency of the D allele.

Abstract
Fibromuscular dysplasia (FMD) is a significant cause of renal artery stenosis, especially in young females. A rare association between FMD and alpha 1-antitrypsin (alpha 1-AT) deficiency has been reported. We compared the alpha 1-AT phenotype distribution in 83 patients with renal arterial FMD with those published for Australian populations. alpha 1-AT phenotyping was performed by isoelectric focusing between pH 4.2 and pH 4.9 on polyacrylamide gels with PiM1M2, PiFM (non-deficiency alleles), PiMS and PiMZ (deficiency alleles) markers. Following phenotyping, alpha 1-AT genotyping was performed in 10 patients to confirm the presence of S and/or Z alleles. The phenotype distribution and allele frequencies were similar to those reported for normal subjects from two Australian populations (72 (86.7%) PiMM phenotype, one (1.2%) PiFM, seven (8.4%) PiMS, two (2.4%) PiMZ and one (1.2%) PiSZ), suggesting that alpha 1-AT deficiency is not a common aetiological factor in renal arterial FMD. However, despite FMD being three times less common in males than females, and carotid artery dissection being a rare occurrence, a male with PiMS deficiency phenotype presented with internal carotid artery dissection and had bilateral renal artery FMD. Further, a patient with PiSZ deficiency phenotype was one of two sisters with FMD and was more severely affected than her PiMM normal phenotype sibling. These two patients from the present series together with nine culled from the literature with alpha 1-AT deficiency phenotype and FMD suggest that the chance combination of alpha 1-AT deficiency and FMD may predispose to severe manifestations of FMD.

Abstract
BACKGROUND With current techniques, renal failure patients are now able to regain near-normal health following renal transplantation. However, the development of premature cardiovascular disease is a major problem. Dyslipidaemia may be an important contributor to this. The use of lipid lowering agents in renal allograft recipients has been limited by potential interaction of these agents with the now widely used immunosuppressive agent, cyclosporine. AIM This study was designed to investigate efficacy and safety of simvastatin in subjects taking either cyclosporine or azothioprine post renal transplantation. METHODS Fifty-one subjects (32 females, 19 males -- mean age 51 +/- 12.5 yr) who were at least 1 yr post transplant, had creatinine < or = 2.5 mmol/L and a total cholesterol > or = 6 mmol/L were enrolled in a prospective, double-blind, placebo-controlled study. After an initial 10-wk dietary period, the last 4 wk on placebo, subjects were randomised to receive either 5 mg simvastatin/d for 6 wk followed by 10 mg simvastatin/d for 6 wk, or matching placebo. After this 12-wk double-blind phase, there was an open-label phase when all subjects were treated with 10 mg simvastatin/d for a period of 36 wk. RESULTS Compared to placebo, 5 mg simvastatin/d significantly decreased total cholesterol by 20% (p < 0.01), low-density lipoprotein cholesterol (LDL cholesterol) by 29% (p < 0.01), and Apolipoprotein B (ApoB) by 26% (p < 0.01). Increasing simvastatin to 10 mg/d did not lead to further significant changes. But high-density lipoprotein cholesterol (HDL cholesterol) increased by 9% (p < 0.01) and Apolipoprotein A1 (ApoA1) by 7% (p < 0.01) only on 10 mg simvastatin/d. During the open-label phase, subjects previously randomised to placebo achieved similar significant changes to their lipoprotein profile. The benefits achieved from simvastatin were maintained to the end of the study. There were three withdrawals from the study, all from the simvastatin/ cyclosporine group. Two subjects had musculoskeletal pain and 1 had abdominal pain. Minor adverse events were similar in both the simvastatin- and placebo-treated groups. CONCLUSION Low-dose simvastatin is an effective and well-tolerated agent in the treatment of dyslipidaemia in renal allograft recipients.

Abstract
This paper examines the effects of smoking on the treatment outcomes of two nonsurgical therapies: (1) scaling and root planing alone (SRP) or (2) controlled-release of subgingivally delivered doxycycline hyclate in a polylactic acid based polymer gel. Subjects from 2 9-month multicenter studies were classified as nonsmokers (never smoked: 100 subjects), former smokers (137 subjects), and current smokers (> or = 10 cigarettes/day: 121 subjects). Clinical parameters were analyzed for treated sites with baseline probing depths > or = 5 mm and for a subset of treated sites with baseline probing depths of > or = 7 mm. Clinical parameters (plaque levels, clinical attachment levels, pocket depths, and bleeding on probing) were analyzed at baseline, 4, 6, and 9 months. In the doxycycline treated group in general, there were neither marked significant differences in clinical attachment gain nor differences in probing depth reduction among the 3 smoking groups. On the other hand, in the scaling and root planing treated group in general, there were significant differences in clinical attachment gain and pocket depth reduction, with non-smokers responding better than former smokers and current smokers at 6 and 9 months. These differences in clinical response between scaling and root planing alone versus controlled-release of locally-delivered doxycycline hyclate among these 3 smoking groups are discussed in relation to treatment implications for smokers.

Abstract
Renal arterial fibromuscular dysplasia (FMD) is a significant cause of renovascular hypertension, especially in younger females. Tobacco constituents have been shown to stimulate proliferation and synthetic activity of cultured human vascular smooth muscle cells. We examined the relationship between smoking and severity of FMD in a group of 50 subjects with the multifocal form of renal arterial FMD. A detailed smoking history was obtained by interview, clinical data at diagnosis of FMD were obtained from medical records, and angiograms were reviewed. Clinical and angiographic features were compared between smokers and non-smokers. Twenty-four subjects were smokers. At the time of diagnosis of FMD, smokers were of younger mean age than non-smokers (38.7 years vs 48.9 years, P < 0.01), had a shorter median history of hypertension (1.5 years vs 8.5 years, P < 0.05), and had a higher prevalence of unilateral renal atrophy (67% vs 27%, P < 0.01). The distribution of age at diagnosis of FMD was unimodal in non-smokers and bimodal, with a discrete group of younger subjects, in smokers. We conclude that cigarette smoking is associated with an earlier onset and increased severity of disease in a susceptible subgroup of patients predisposed to multifocal renal arterial FMD.

Abstract
OBJECTIVE To develop a way of measuring long-term outcomes after traumatic brain injury (TBI) that takes account of individual circumstances. DESIGN Reports by head-injured people and their families about problems and coping strategies were elicited via semi-structured interviews. Specially designed computer software was used to record problems and strengths and to measure their impact for the individual on four handicap dimensions. SETTING Interviews took place in the respondents' homes. SUBJECTS Between 1992 and 1997 the services at 10 rehabilitation centres in England were evaluated. Subjects were men and women aged between 16 and 65 who had suffered TBI and who had been referred for treatment to one of the centres under study. INTERVENTIONS Head-injured people and their families were interviewed three months, 18 months and in some cases 36 months after recruitment. MAIN OUTCOME MEASURES The Hospital Anxiety and Depression Scale (HAD) and the Functional Independence/Assessment Measure (FIM/FAM) were used to validate relevant dimensions of the new scale. RESULTS A measure of long-term outcome was developed and called the Community Outcome Scale. Relevant dimensions of the scale showed significant correlation with the HAD and with items of the FIM/FAM. CONCLUSION The scale captures information which no other instrument does, and merits further validation.

Abstract
BACKGROUND A kidney transplant recipient inadvertently contracted donor-origin melanoma, which was found to be very advanced at presentation. Withdrawal of immunosuppression failed to induce rejection, and interferon-alpha was required. When florid allograft rejection was in progress, the allograft was removed, before it was recognized that the transplanted melanoma was not being simultaneously rejected. METHODS Subsequent immunotherapy was required, which largely recapitulated treatment of recognized value in autologous melanoma and included interferon-alpha, use of cultured melanoma cells as tumor vaccine, pooled allogeneic cell vaccination, and adoptive immunotherapy using lymphokine-activated killer cells. RESULTS Prolonged immunotherapy eradicated the widespread malignancy, and the patient went on to a successful second renal transplant, with follow-up of over 24 months. CONCLUSIONS This unique case demonstrates the successful cure of advanced transplanted melanoma through the use of immunotherapy, which did not require sophisticated tumor vaccine technology, and successful retransplantation.

Abstract
OBJECTIVE Hox genes encode DNA transcription regulatory proteins that contain a conserved 61 amino acid protein called the homeodomain. Although best known for their role in cellular differentiation during embryonic development, aberrant expression of these genes has been associated with hematologic and solid neoplasms. The purpose of this study was to determine the relative expression of HOXD10 in human endometrial adenocarcinomas. METHODS mRNA was isolated from 7 normal endometrial specimens and 28 endometrial adenocarcinoma specimens. cDNA was synthesized using random hexamer primers. The expression of HOXD10 relative to beta-tubulin (internal control) was assessed by densitometric comparison of co-amplified Phosphorus-32 (32P) labeled gene products separated by agarose gel electrophoresis. Direct sequencing of purified HOXD10 polymerase chain reaction product was also performed. RESULTS The sequence of the purified HOXD10 product corresponds to the known DNA sequence reported in the National Institute of Health Gene Bank. mRNA expression of HOXD10 relative to beta-tubulin is significantly lower in endometrial carcinomas than in normal endometrium. Furthermore, the ratio of HOXD10 to beta-tubulin expression varies inversely with the histologic grade of the tumor (P = .0009). CONCLUSION Cancer is a multistep process involving the aberrant expression of genes that regulate cell growth and differentiation. Human HOXD10 gene expression is altered in endometrial carcinoma and varies with the histologic grade of differentiation. This observation supports the theory that homeobox genes play a role in oncogenesis.

Abstract
OBJECTIVES To determine the incidence of transitional cell carcinoma (TCC) in a renal transplant population and to compare the pattern of neoplasia in patients with analgesic nephropathy (AN) with that in other patients. PATIENTS AND METHODS Using the Australia and New Zealand Dialysis and Transplant Registry, renal transplant recipients of the Princess Alexandra Hospital with TCC were identified. They were separated into two groups based on their primary disease, i.e. AN (group 1) and other causes of renal failure (group 2). The age at diagnosis of TCC, site, grade, stage of TCC and outcome were then compared between the groups. RESULTS There were 250 (15%) patients in group 1 and 1424 (85%) in group 2; seven patients in each group were found to have TCC, which thus occurred more frequently in the AN group (2.8%) than in group 2 (0.49%). In group 1, five patients died, four from metastatic disease; of these, the mean time from transplantation to diagnosis of the initial tumour was 4.4 years, with a mean time from diagnosis to death of 9 months. In contrast, there were no deaths from metastatic disease in group 2. In group 1, all patients had upper tract tumours, with five patients also having bladder involvement. The upper tract tumours tended to be of a high stage and grade (grade II-III) and were aggressive. In group 2, all the tumours were confined to the bladder and tended to be of low stage and grade (grade I-II Ta). CONCLUSIONS Patients undergoing renal transplantation as a result of AN are at high risk of developing TCCs of the upper urinary tracts. These tumours tend to be of a high grade and stage and the patients have a poor outcome. Screening with urine analysis and voided urine cytology do not appear to be reliable for the early diagnosis of upper renal tract TCCs in the renal transplant patient. We advocate annual cystoscopy and retrograde ureteric catheterization with washings, brushings and radiological imaging to diagnose upper tract TCCs at an early stage. These patients should also be screened before transplantation using the same technique.

Abstract
Fourteen patients with major depression, resistant to previous pharmacotherapies, were treated by the addition of lithium (target range 0.6-0.8 mmol/l) to nefazodone (≥400 mg/day) and were prospectively monitored for 6 weeks to assess safety and tolerability. There were 42 emergent adverse events-most commonly headache, nausea, gastro-intestinal disturbances, tremor, polyuria/polydipsia, dry mouth and tiredness. Information on ten additional patients receiving combined treatment with lithium and nefazodone was collected by retrospective chart review, and it was found that similar adverse events (tremor, dry mouth and tiredness) had occurred in these patients. We conclude that when lithium is added to nefazodone, new adverse events do occur, but that the treatment is safe and tolerable.

Abstract
The potential efficacy and tolerability of new antidepressants can best be assessed through randomized controlled trials (RCTs). However, the patient population in antidepressant studies is a highly selected group, so the results from such studies may not be applicable to routine clinical practice. This paper describes a questionnaire survey of senior psychiatrists in the UK aimed at evaluating early clinical experience with reboxetine, a new, selective noradrenaline re-uptake inhibitor (selective NRI) recently introduced in the UK for the treatment of depression. Psychiatrists were asked for details of their experience with reboxetine in depression, illustrated with representative case histories. The spontaneous adverse events reported to the Medicines Control Agency (MCA) were also reviewed. Information was collected on over 250 patients, 50% of whom had responded sub-optimally to previous physical treatments for this current episode; over 50% had co-morbid psychiatric disorders, and 29.1% had coexisting physical illness. Most of the patients were treated with 8 mg/day of reboxetine. The overall clinical response to reboxetine, as judged by the treating doctor, was considered 'good' in over 65% of patients. Three-quarters of them showed 'good/very good' improvement in their symptoms; the same proportion achieved a 'good/very good' improvement in activities of daily living. Two-thirds of patients did not report any troublesome side-effects, the profile being consistent with that seen in RCTs. Analysis of spontaneous adverse events reported to the MCA has not as yet revealed any surprises. Early clinical experience with reboxetine in routine practice is encouraging. Efficacy, tolerability and simple dosing appear to be particular benefits to patients. Consistent with data from RCTs involving reboxetine, recovery of function accompanies symptomatic improvement, which may be related to the selective effects of the drug on noradrenaline.

Abstract
Sclerosing peritonitis is a rare, but serious complication of peritoneal dialysis. To attempt the early identification of patients at risk of developing this life-threatening problem, we performed a cross-sectional study of 15 patients: five had died of sclerosing peritonitis, four had stopped peritoneal dialysis because sclerosing peritonitis was suspected, and six were considered to be at increased risk because of more than 4 years on peritoneal dialysis. We examined the duration of dialysis, number of episodes of peritonitis, strength of peritoneal dialysis bags, the type of dialysate, and the use of beta blockers. We also used a number of radiologic investigations, including abdominal x-ray, a measure of colonic transit using radiopaque markers, abdominal ultrasound, and computed tomography scanning. Of the clinical features, only duration of dialysis could be shown to be an important risk factor. We identified a number of radiologic features that we believe to be early signs of peritoneal sclerosis. The two computed tomography scans that were available from the deceased patients demonstrated peritoneal thickening, as did those from three of the four living patients who stopped peritoneal dialysis with suspected disease and from two of the six patients who had been on peritoneal dialysis for over 4 years. Ultrasound demonstrated a characteristic trilaminar appearance in four patients, but was unable to be demonstrated without peritoneal fluid in situ. Delayed colon transit was demonstrated in three of the four living patients with clinically suspected disease. Radiologic screening to detect sclerosing peritonitis early in high-risk patients requires further study.
