Abstract
OBJECTIVE Patterns of radiographic osteoarthritis (ROA) of the hand are often examined by row, with the four joints of the thumb studied inconsistently. The objectives of this study were to determine relationships of ROA at different hand joints, use the findings to define radiographic sub-groups and investigate their associations with pain and function. METHODS Sixteen joints in each hand were scored for the presence of ROA in a community-dwelling cohort of adults, 50-years-and-over, with self-reported hand pain or problems. Principal components analysis (PCA) with varimax rotation was used to study patterns of ROA in the hand joints and identify distinct sub-groups. Differences in pain and function between these sub-groups were assessed using Australian/Canadian Osteoarthritis Index (AUSCAN), Grip Ability Test (GAT) and grip and pinch strength. RESULTS PCA was undertaken on data from 592 participants and identified four components: distal interphalangeal joints (DIPs), proximal interphalangeal joints (PIPs), metacarpophalangeal joints (MCPs), thumb joints. However, the left thumb interphalangeal (IP) joint cross-loaded with the PIP and thumb groups. On this basis, participants were categorised into four radiographic sub-groups: no osteoarthritis (OA), finger only OA, thumb only OA and combined thumb and finger OA. Statistically significant differences were found between the sub-groups for AUSCAN function, and in women alone for grip and pinch strength. Participants with combined thumb and finger OA had the worst scores. CONCLUSION Individual thumb joints can be clustered together as a joint group in ROA. Four radiographic sub-groups of hand OA can be distinguished. Pain and functional difficulties were highest in participants with both thumb and finger OA.

Abstract
In this report, we describe a patient with a de novo BRCA2 gene mutation (5301insA) who developed early onset breast cancer with no strong family history of the disease. Only three similar instances have been reported previously. Subsequent site-specific analysis in her parents showed that neither carried the mutation previously identified in their daughter. Various possible explanations for this finding were excluded. Paternity was confirmed using 13 highly polymorphic markers, thereby illustrating that the patient carried a de novo mutation in the BRCA2 gene. The 5301insA mutation has been well described and reported many times in the Breast Cancer Information Core online Breast Cancer Mutation database. This finding illustrates the importance of determining the incidence of de novo BRCA mutations and is of significant clinical value to breast cancer prevention and management. Our case report presents the fourth case in which a de novo germline mutation in a BRCA1/2 gene has been identified.

Abstract
PURPOSE Adrenal incidentaloma is often diagnosed in patients with familial adenomatous polyposis, because they frequently undergo abdominal imaging and have a raised incidence of adrenal incidentaloma. This study investigates the natural history of adrenal incidentaloma in familial adenomatous polyposis, and suggests a schema for management. METHODS An original cohort of 14 familial adenomatous polyposis patients with adrenal incidentaloma, identified prospectively 12 years ago, was followed up clinically and radiologically. A further group of 16 patients was also identified. All had lesions >1 cm. For both cohorts, characteristics of patients (genotype, age at diagnosis, concomitant diagnoses) and incidentaloma (size, laterality, rate of growth, outcome) are described. RESULTS Overall, 3 of 30 patients underwent adrenalectomy; one patient had pheochromocytoma and another had an adenoma of borderline malignancy. A further three lesions were radiologically suspicious for malignancy at the time of diagnosis; one was in a patient who was unfit for surgery but died of nonadrenal causes after nine years. None of the lesions radiologically benign at diagnosis showed an aggressive course, but one patient required referral for surgery after 12 years because of a slow increase in size of the lesion. There were no associations with genotype. CONCLUSIONS Familial adenomatous polyposis-associated adrenal incidentaloma may warrant long-term follow-up. Although the natural history is similar to lesions occurring sporadically, these patients have concomitant familial adenomatous polyposis-associated manifestations under radiologic surveillance. In this rare condition, development of a robust protocol will require evidence from worldwide patient cohorts. However, a tailored schema is suggested as a consistent basis for future modification.

Abstract
AIM To investigate the effect of different colour three-dimensional (3D) displays on polyp detection at virtual colonoscopy (VC). METHODS Five VC trained observers were shown "brief flashes" (lasting 0.2s) of 125 3D endoluminal image snap-shots, repeated for each of six display colours (750 images total). One hundred images contained a single polyp (diameter range 5-42 mm) and 25 contained no polyp ("normal"). Images were reviewed in random order over five reading sessions, readers recording either normality or presence and location of a polyp. Multilevel logistic regression was used to examine any influence of colour on polyp detection stratified according to polyp size (medium 5-9 mm/large >or=10mm). The kappa statistic was used to assess effect of colour on observer agreement. RESULTS Individual reader polyp detection rates ranged between 75-94%. Compared to the default pink "soft tissue" display, the odds of polyp detection were 0.65 (CI 0.41,1.01) for green, 0.82 (0.53,1.30) for blue, 1 (0.63,1.59) for red, 1.12 (0.7,1.79) for monochrome, and 1.15 for yellow (0.72,1.84). Overall, there was no significant difference between the displays (p=0.11). Including normal cases, there was no overall difference in correct case classification between the six colours (p=0.44). The odds of detecting large versus medium polyps was significantly greater for 3/5 observers; odds ratio (OR) 2.84-10.1, although unaffected by display colour (p=0.3). CONCLUSION The background colour display generally has a minimal effect on polyp detection at VC, although green should be avoided.

Abstract
Although persistent translation arrest correlates with the selective vulnerability of post-ischemic hippocampal cornu ammonis 1 (Ammon's horn) (CA1) neurons, the mechanism of persistent translation arrest is not fully understood. Using fluorescent in situ hybridization and immunofluorescence histochemistry, we studied colocalization of polyadenylated mRNAs [poly(A)] with the following mRNA binding factors: eukaryotic initiation factor (eIF) 4G (translation initiation factor), HuR (ARE-containing mRNA stabilizing protein), poly-adenylated mRNA binding protein (PABP), S6 (small ribosomal subunit marker), T cell internal antigen (TIA-1) (stress granule marker), and tristetraprolin (TTP) (processing body marker). We compared staining in vulnerable CA1 and resistant CA3 from 1 to 48 h reperfusion, following 10 min global ischemia in the rat. In both CA1 and CA3 neurons, cytoplasmic poly(A) mRNAs redistributed from a homogenous staining pattern seen in controls to granular structures we term mRNA granules. The mRNA granules abated after 16 h reperfusion in CA3, but persisted in CA1 neurons to 48 h reperfusion. Protein synthesis inhibition correlated precisely with the presence of the mRNA granules. In both CA1 and CA3, the mRNA granules colocalized with eIF4G and PABP, but not S6, TIA-1 or TTP, indicating that they were neither stress granules nor processing bodies. Colocalization of HuR in the mRNA granules correlated with translation of 70 kDa inducible heat shock protein, which occurred early in CA3 (8 h) and was delayed in CA1 (36 h). Thus, differential compartmentalization of mRNA away from the 40S subunit correlated with translation arrest in post-ischemic neurons, providing a concise mechanism of persistent translation arrest in post-ischemic CA1.

Abstract
Sign language interpreters suffer from high levels of upper extremity disorders and burnout due to the physical and cognitive demands of interpreting. The objective of this research was to quantify the wrist kinematics of interpreting and to assess how speaker pace and psychosocial stress influence wrist kinematics. Professional interpreters interpreted a pre-recorded lecture, while the speaking pace of the lecture varied. One group of subjects was exposed to environmental conditions intended to induce stress. Several wrist kinematic variables of interpreting exceeded previously established high risk benchmarks for development of upper extremity disorders in industrial tasks. Wrist velocity and acceleration increased significantly with pace, with increases ranging from 10.7-18.6%. Increased psychosocial stress resulted in significant increase of left hand (non-dominant) wrist velocity and acceleration, with increases ranging from 14.8-19.5%. These results provide an objective assessment of the biomechanical demands of interpreting and support earlier research into different types of work, which found deleterious effects of psychosocial stress on the biomechanical responses of the lower back.

Abstract
OBJECTIVE Currently there is no agreed "gold standard" definition of radiographic hand osteoarthritis (RHOA) for use in epidemiological studies. We therefore undertook a systematic search and narrative review of community-based epidemiological studies of hand osteoarthritis (OA) to identify (1) grading systems used, (2) definitions of radiographic OA for individual joints and (3) definitions of overall RHOA. METHODS The following electronic databases were searched: Medline, Embase, Science Citation Index and Ageline (inception to Dec 2006). The search strategy combined terms for "hand" and specific joint sites, OA and radiography. Inclusion and exclusion criteria were applied. Data were extracted from each paper covering: hand joints studied, grading system used, definitions applied for OA at individual joints and overall RHOA. RESULTS Titles and abstracts of 829 publications were reviewed and the full texts of 399 papers were obtained. One hundred fifty-two met the inclusion criteria and 24 additional papers identified from screening references. Kellgren and Lawrence (K&L) was the most frequently applied grading system used in 80% (n=141) of studies. In 71 studies defining OA at the individual joint level 69 (97%) used a definition of K&L grade > or = 2. Only 53 publications defined overall RHOA, using 21 different definitions based on five grading systems. CONCLUSION The K&L scheme remains the most frequently used grading system. There is a consistency in defining OA in a single hand joint as K&L grade > or = 2. However, there are substantial variations in the definitions of overall RHOA in epidemiological studies.

Abstract
AIM To investigate the effect of a virtual colonoscopy (VC) computed-assisted detection (CAD) system on polyp detection by trained radiographers. MATERIALS AND METHODS Four radiographers trained in VC interpretation and utilization of CAD systems read a total of 62 endoscopically validated VC examinations containing 150 polyps (size range 5-50mm) in four sessions, recording any polyps found and the examination interpretation time, first without and then with the addition of CAD as a "second reader". After a temporal separation of 6 weeks to reduce recall bias, VC examinations were re-read using "concurrent reader" CAD. Interpretation times, polyp detection, and number of false-positives were compared between the different reader paradigms using paired t and paired exact tests. RESULTS Overall, use of "second reader" CAD significantly improved polyp detection by 12% (p<0.001, CI 6%,17%)) from 48 to 60%. There was no significant improvement using CAD as a concurrent reader (p=0.20; difference of 7%, CI -3%, 16%) and no significant overall difference in recorded false-positives with second reader or concurrent CAD paradigms compared with unassisted reading (p=0.25 and 0.65, respectively). The mean interpretation time was 21.7 min for unassisted reading, 29.6 (p<0.001) min for second reader and 19.1 min (p=0.12) for concurrent reading paradigms. CONCLUSION CAD, when used as a second reader, can significantly improve radiographer reading performance with only a moderate increase in interpretation times.

Abstract
Cholera epidemics have a recorded history in the eastern Africa region dating to 1836. Cholera is now endemic in the Lake Victoria basin, a region with one of the poorest and fastest growing populations in the world. Analyses of precipitation, temperatures, and hydrological characteristics of selected stations in the Lake Victoria basin show that cholera epidemics are closely associated with El Niño years. Similarly, sustained temperatures high above normal (T(max)) in two consecutive seasons, followed by a slight cooling in the second season, trigger an outbreak of a cholera epidemic. The health and socioeconomic systems that the lake basin communities rely upon are not robust enough to cope with cholera outbreaks, thus rendering them vulnerable to the impact of climate variability and change. Collectively, this report argues that communities living around the Lake Victoria basin are vulnerable to climate-induced cholera that is aggravated by the low socioeconomic status and lack of an adequate health care system. In assessing the communities' adaptive capacity, the report concludes that persistent levels of poverty have made these communities vulnerable to cholera epidemics.

Abstract
A 15-Country collaborative cohort study was conducted to provide direct estimates of cancer risk following protracted low doses of ionizing radiation. Analyses included 407,391 nuclear industry workers monitored individually for external radiation and 5.2 million person-years of follow-up. A significant association was seen between radiation dose and all-cause mortality [excess relative risk (ERR) 0.42 per Sv, 90% CI 0.07, 0.79; 18,993 deaths]. This was mainly attributable to a dose-related increase in all cancer mortality (ERR/Sv 0.97, 90% CI 0.28, 1.77; 5233 deaths). Among 31 specific types of malignancies studied, a significant association was found for lung cancer (ERR/Sv 1.86, 90% CI 0.49, 3.63; 1457 deaths) and a borderline significant (P = 0.06) association for multiple myeloma (ERR/Sv 6.15, 90% CI <0, 20.6; 83 deaths) and ill-defined and secondary cancers (ERR/Sv 1.96, 90% CI -0.26, 5.90; 328 deaths). Stratification on duration of employment had a large effect on the ERR/Sv, reflecting a strong healthy worker survivor effect in these cohorts. This is the largest analytical epidemiological study of the effects of low-dose protracted exposures to ionizing radiation to date. Further studies will be important to better assess the role of tobacco and other occupational exposures in our risk estimates.
