Abstract
In sub-Saharan Africa, chronic hepatosplenomegaly, with palpable firm/hard organ consistency, is common, particularly among school-aged children. This morbidity can be caused by long-term exposure to malaria, or by Schistosoma mansoni, and it is exacerbated when these two occur together. Although immunological mechanisms probably underlie the pathogenic process, these mechanisms have not been identified, nor is it known whether the two parasites augment the same mechanisms or induce unrelated processes that nonetheless have additive or synergistic effects. Kenyan primary schoolchildren, living in a malaria/schistosomiasis co-transmission area, participated in cross-sectional parasitological and clinical studies in which circulating immune modulator levels were also measured. Plasma IL-12p70, sTNF-RII, IL-10 and IL-13 levels correlated with relative exposure to malaria, and with hepatosplenomegaly. Soluble-TNF-RII and IL-10 were higher in children infected withS. mansoniHepatosplenomegaly caused by chronic exposure to malaria was clearly associated with increased circulating levels of pro-inflammatory mediators, with higher levels of regulatory modulators, and with tissue repair cytokines, perhaps being required to control the inflammatory response. The higher levels of regulatory modulators amongstS. mansoniinfected children, compared to those without detectableS. mansoni and malarial infections, but exposed to malaria, suggest thatS. mansoniinfection may augment the underlying inflammatory reaction.

Abstract
OBJECTIVE To develop and validate a clinically feasible measure of communication effectiveness for people with any type of communication problem following stroke. DESIGN Cross-sectional, interview-based, psychometric study, building on the development phase for construction of the Communication Outcome after Stroke (COAST) scale. SETTING A community sample from the northwest of England, UK. SUBJECTS One hundred and two people with communication problems (aphasia and/or dysarthria) following a stroke, within the previous 4-12 months. INTERVENTIONS Administration of the COAST scale, on two occasions, within a two-week period, and collection of demographic and other data relating to disability, degree of aphasia (where appropriate) and hospital diagnosis of aphasia/dysarthria. MAIN MEASURES Acceptability (missing values), reliability (internal consistency and test-retest reliability) and item analysis (item redundancy). RESULTS Ninety-seven (visit 1) and 98 (visit 2) respondents provided usable data for the psychometric analysis. The 29-item COAST scale showed good acceptability (few missing values, sample spread 28-100%), internal consistency and test-retest reliability for the scale (alpha = 0.95; ICC = 0.90) and its subscales (alpha = 0.65-0.93; ICC = 0.72-0.88), but possible item redundancy. A revised scale of 20 items was produced, demonstrating good internal consistency and test-retest reliability (alpha = 0.83-92; ICC = 0.72-0.88). CONCLUSIONS The COAST is a patient-centred, practical and reliable measure that can be used to assess self-perceived communication effectiveness for people with aphasia and/or dysarthria. Further testing on construct validity and responsiveness to change is needed before the measure can be firmly recommended for use within clinical practice and research.

Abstract
BACKGROUND Cholecystectomy is made hazardous by distortion of the anatomy of Calot's triangle by acute or chronic inflammation. Laparoscopic subtotal cholecystectomy (LSTC) without cystic duct ligation is an alternative to conversion to open surgery in difficult cases. METHODS This prospective study included all cholecystectomies performed in a district general hospital upper gastrointestinal unit between 2003 and 2005, after the introduction of LSTC. RESULTS Of 889 laparoscopic cholecystectomies, 28 LSTCs without cystic duct ligation were performed in 18 men and ten women of median age 68 years. Median operating time was 90 min and median duration of hospital stay was 3 days. Two temporary bile leaks resolved spontaneously on days 14 and 19. Three patients required endoscopic retrograde cholangiopancreatography, extraction of bile duct stones and stent insertion for persistent leaks. All five bile leaks were expected from peroperative findings. One patient had a myocardial infarction and one developed a subphrenic abscess. There were no deaths. Open conversion rates were reduced from 5.0 per cent in 1997-2002 to 0.3 per cent in 2005 (P < 0.001). CONCLUSION LSTC without cystic duct ligation is an alternative to open conversion when dissection of Calot's triangle is hazardous. Bile leaks are predictable and readily managed.

Abstract
Samples of commercially pure nickel have been annealed in air at 0.68T(m) (900 degrees C) for 1, 2 and 3 h in order to study the relationship between the grain growth characteristics and grain boundary misorientation, particularly annealing twins (Sigma 3). Orientation mapping by electron backscatter diffraction was used to obtain the experimental data. Anomalous grain growth was observed in commercially pure nickel after each of the anneals. The main findings are as follows. The texture was mainly {100}<001> and {112}<111> and it was more pronounced in coarse-grained areas than in fine-grained areas. The length fraction of Sigma 3s (annealing twins) increased with annealing time and therefore with the level of anomalous grain growth. Two to three twins per grain were sited in coarse-grained regions whereas less than one twin per grain was sited in fine-grained regions. It is suggested that the nucleation and growth of twinning is mechanistically linked to anomalous grain growth.

Abstract
Aberrations are known to severely compromise image quality in optical microscopy, especially when high numerical aperture (NA) lenses are used in confocal fluorescence microscopy (CFM) and two-photon microscopy (TPM). The method of adaptive optics may correct aberrations and restore diffraction limited operation. So far the problem of aberrations that occur in the imaging of biological specimens has not been quantified. However, this information is essential for the design of adaptive optics systems. We have therefore built an interferometer incorporating high NA objective lenses to measure the aberrations introduced by biological specimens. The measured wavefronts were decomposed into their Zernike mode content in order both to classify and quantify the aberrations. We calculated the potential benefit of correcting different numbers of Zernike modes using different NAs in an adaptive CFM by comparing the signal levels before and after correction. The results indicate that adaptive correction of low order Zernike modes can provide significant benefit for many specimens. The results also show that quantitative fluorescence microscopy may be strongly affected by specimen induced aberrations in non-adaptive systems.

Abstract
OBJECTIVE Obesity is a major problem among chronically psychotic patients. METHOD We assessed body mass index (BMI) of chronically psychotic patients on admission to a state mental hospital and in follow-up. We also compared patient BMI to staff BMI. RESULTS The initial patient BMI (26.4 +/- 5.8 kg/m2) was in the overweight range. The patient BMI (29.1 +/- 5.8 kg/m2) increased (P < 0.0001) on follow-up and almost reached the level of obesity. Staff BMI (35.1 +/- 8.6 kg/m2) was in the obese range with 64.9% meeting criteria of obesity and 29.9% meeting criteria of morbid obesity. African-American women made up 84.5% of clinical-care staff and constitute the race-sex mix most vulnerable to obesity in the US. Morbid obesity (BMI > or = 40 kg/m2) was five times more common among these African-American female clinical-care staff than among African-American women in the general US population. CONCLUSION Our findings may have treatment implications for chronically psychotic patients at risk for obesity.

Abstract
The Klato-Katz method is widely used for diagnosing helminth infections in epidemiological surveys, but is known to have a low sensitivity. In the case of Schistosoma mansoni, statistical methods have been developed to compensate for the poor sensitivity, but the same is not true of any other helminth parasite, or infections with multiple-helminth species. We screened 101 schoolchildren from a rural area of Côte d'Ivoire over 5 consecutive days and made 5 Kato-Katz readings from each stool specimen. We estimated single and dual-species infections with S. mansoni and hookworm based on raw egg count data and after developing a latent-class model. The cumulative prevalence of co-infections was estimated at 9.9% after reading slides on the first day, and 57.0% after reading all 25 slides per person. The latent class model yielded a co-infection prevalence estimate of 79.6%, with marginal prevalence estimates for hookworm and S. mansoni infections of 83.9% and 91.6% respectively. The sensitivities of a single Kato-Katz thick smear for detection of S. mansoni alone, hookworms alone, or S. mansoni plus hookworms were 22.4%, 8.0% and 17.7%, respectively. In the current setting this could be attributable to low infection intensities of both parasites, combined with intra-specimen and day-to-day variation in egg output. If confirmed in other settings, these findings have implications for estimating the prevalence of multiple species helminth infections, and hence the design and implementation of efficacious and cost-effective control programmes.

Abstract
Peri-portal fibrosis can be a serious sequelae of Schistosoma mansoni infection. Age or duration of exposure have been identified as important risk factors, but their relative importance cannot be easily separated. Here, we have compared two cohorts, aged 6-50 years and resident for ten years or since birth, from two neighbouring villages (Booma and Bugoigo) on the eastern shore of Lake Albert, Uganda. Parasitological measurements were similar, whereas the prevalence of peri-portal fibrosis was 5-fold higher in Booma. Data from the cohorts were pooled to assess the relative contribution of age and duration of residency on the risk of disease. Amongst adults, duration of residency was the critical risk factor--individuals aged 17-31 years resident for more 22 years had an almost 12-fold increased risk of fibrosis than those resident for less than 15 years. Height-standardised Splenic Vein Diameter (SVD), Portal Vein Diameter (PVD), Para-sternal Liver Length (PLL) and Spleen Length (SL) values were all higher in Booma, and each organometric parameter except PLL increased with the severity of fibrosis. Our results clearly demonstrate that duration of exposure is a critical risk factor for the development of peri-portal fibrosis and its sequelae in adults. This parameter should therefore be a routine measurement during epidemiological surveys of S. mansoni.

Abstract
INTRODUCTION Previous research has reported rural-urban differences in health concerns and access issues. However, very little of this has concerned young people, and what has been published has been mainly from countries other than Australia and may not generalise to Australian youth. The study described in this paper is a subset of a larger study on health concerns and access to healthcare for younger people (12-17 years) living in New South Wales (NSW), Australia. This paper reports findings on rural-urban similarities and differences. The specific study objective was to identify and describe rural-urban differences, especially those associated with structural disadvantage. METHOD The reported findings form part of a larger state-wide cross-sectional study of access to healthcare among NSW adolescents. Adolescents were drawn from high schools in ten of the 17 Area Health Services in NSW. These Area Health Services were selected because they represent most aspects of rural-urban NSW with respect to population characteristics and health services. Eighty-one focus groups were conducted with adolescents (35 with boys and 46 with girls), of which 56 were conducted in urban, 22 in rural and 3 in regional areas. The focus groups were tape-recorded, transcribed and analysed using the computer software package NUD*IST 4. RESULTS The analysis revealed certain health concerns that were common to both rural and urban adolescents: use of alcohol and illicit drugs, bullying, street safety, diet and body image, sexual health, stress and depression. However, certain concerns were mentioned more frequently in rural areas (eg depression), and two concerns were raised almost exclusively by rural youth (youth suicide and teenage pregnancy). There were also structural differences in service provision: adolescents in rural areas reported disadvantage in obtaining access to healthcare (limited number of providers and lengthy waiting times); having only a limited choice of providers (eg only one female doctor available), and cost (virtually no bulk billing--ie direct charge to Medicare with no patient co-payment). A lack of confidentiality as a barrier to seeking service access was raised by both rural and urban youth, but was a major concern in rural areas. No issues specific to urban areas were raised by urban youth. Male and female rural adolescents were more likely than urban adolescents to express concerns over limited educational, employment and recreational opportunities, which they believed contributed to their risk-taking behaviour. Gender differences were evident for mental health issues, with boys less able to talk with their peers or service providers about stress and depression than girls. These gender differences were evident among adolescents in both rural and urban areas, but the ethos of a self-reliant male who does not ask for help was more evident among rural boys. CONCLUSIONS While Australian rural and urban youth shared many health concerns, rural-urban differences were striking in the almost exclusive reporting of youth suicide and teenage pregnancy by rural adolescents. The findings suggest that structural disadvantage in rural areas (limited educational, employment opportunities, and recreational facilities) impact adversely on health outcomes, particularly mental health outcomes, and contribute to risk-taking behaviour. Such disadvantages should be considered by health-service policy makers and providers to redress the imbalance. Gender differences were also evident and efforts to target the specific needs of Australian adolescent boys are warranted.

Abstract
Laparoscopic antireflux surgery has been performed in neurologically impaired and scoliotic children. We aimed to assess the effectiveness of laparoscopic fundoplication in mentally normal children with gastroesophageal reflux disease that failed to respond to medical therapy. Data were prospectively collected (symptoms, medical therapy, endoscopies' findings) on 12 children (nine boys, three girls) aged 9-15 years with gastroesophageal reflux disease. Pre- and postoperative ambulatory 24-h pH and DeMeester and Johnson scores were also recorded. Effectiveness of surgery was assessed by comparison of pre- and postoperative total acid exposure time, Visick grade, need for antireflux medication and symptom scores. In total, 11 children underwent a laparoscopic Nissen fundoplication and one underwent a Toupet procedure. Median length of stay was 2 (2-3) nights. The median preoperative pH acid exposure time (AET) was 4.7 (0.8-16.4) percent compared with postoperative AET of 0.4 (0-3) percent. Early postoperative dysphagia occurred in four out of 12 patients, requiring a total of six dilatations. Postoperative Visick scores were: grade I=7 and grade II=5. Laparoscopic fundoplication can be safely performed and is effective in children with GERD who have failed to respond to medical therapy.

Abstract
We evaluated a policy of performing laparoscopic antireflux surgery without tailoring the procedure to the results of preoperative esophageal motility tests. A total of 117 patients (82 with normal esophageal motility; 35 with ineffective motility, IEM) underwent laparoscopic Nissen fundoplication for symptomatic gastroesophageal reflux. There were no significant differences in preoperative symptom length, dysphagia, DeMeester symptom scores, acid exposure times or lower esophageal sphincter pressures between the two groups. Both groups showed postoperative improvements in DeMeester symptom scores, dysphagia and acid exposure, with no differences between groups. At 1 year after surgery, 95% of the normal motility group and 91% of the IEM group had a good/excellent outcome from surgery. None of the IEM group required postoperative dilatation or reoperation. Patients with IEM fare equally well from laparoscopic Nissen fundoplication as those with normal esophageal motility. There is no merit in tailoring antireflux surgery to the results of preoperative motility tests.
