Abstract
Robin sequence (RS) has many genetic and nongenetic causes, including isolated Robin sequence (iRS), Stickler syndrome (SS), and other syndromes (SyndRS). The purpose of this study was to determine if the presence and type of cleft palate varies between etiologic groups. A secondary endpoint was to determine the relationship of etiologic group, cleft type, and mortality. Retrospective chart review of patients with RS at two high-volume craniofacial centers. 295 patients with RS identified. CP was identified in 97% with iRS, 95% with SS, and 70% of those with SyndRS (p < .0001). U-shaped CP was seen in 86% of iRS, 82% with SS, but only 27% with SyndRS (p < .0001). At one institution, 12 children (6%) with RS died, all from the SyndRS group (p < .0001). All died due to medical comorbidities related to their syndrome. Only 25% of children who died had a U-shaped CP. The most common palatal morphology among those who died was an intact palate. U-shaped CP was most strongly associated with iRS and SS, and with a lower risk of mortality. RS with submucous CP, cleft lip and palate or intact palate was strongly suggestive of an underlying genetic syndrome and higher risk of mortality.

Abstract
Multimorbidity is increasingly the primary concern of healthcare systems globally with substantial implications for patient outcomes and resource cost. A critical knowledge gap exists as to the magnitude of multimorbidity in primary care practice in low and middle income countries with available information limited to prevalence. In India, primary care forms the bulk of the health care delivery being provided through both public (community health center) and private general practice setting. We undertook a study to identify multimorbidity patterns and relate these patterns to severity among primary care attendees in Odisha state of India. A total of 1649 patients attending 40 primary care facilities were interviewed using a structured multimorbidity assessment questionnaire. Multimorbidity patterns (dyad and triad) were identified for 21 chronic conditions, functional limitation was assessed as a proxy measure of severity and the mean severity score for each pattern, was determined after adjusting for age. The leading dyads in younger age group i.e. 18–29 years were acid peptic disease with arthritis/ chronic back ache/tuberculosis /chronic lung disease, while older age groups had more frequent combinations of hypertension + arthritis/ chronic lung disease/vision difficulty, and arthritis + chronic back ache. The triad of acid peptic disease + arthritis + chronic backache was common in men in all age groups. Tuberculosis and lung diseases were associated with significantly higher age-adjusted mean severity score (poorer functional ability). Among men, arthritis, chronic backache, chronic lung disease and vision impairment were observed to have highest severity) whereas women reported higher severity for combinations of hypertension, chronic back ache and arthritis. Given the paucity of studies on multimorbidity patterns in low and middle income countries, future studies should seek to assess the reproducibility of our findings in other populations and settings. Another task is the potential implications of different multimorbidity clusters for designing care protocols, as currently the protocols are disease specific, hardly taking comorbidity into account.

Abstract
BACKGROUND Gout is a common inflammatory arthritis that affects ∼4% of the US population. Most patients with gout are >50 years of age and have multiple comorbidities. Gout is caused by the deposition of monosodium urate crystals in joints secondary to hyperuricemia. Gout typically presents as an acute painful inflammation (flare) involving one or more joint. Left untreated it can progress into a more chronic polyarthritis. Acute gout flare treatment options include colchicine, non-steroidal anti-inflammatory drugs (NSAIDs), and corticosteroids. The safety and efficacy of colchicine, especially in the presence of comorbidity and potential contraindications, has only recently been systematically investigated. METHODS Through the use of a systematic computer-based literature analysis, this pharmacoeconomic review evaluated costs, risks, and benefits of Colcrys (colchicine) compared with other treatments for gout in the US. RESULTS Both colchicine and NSAIDs are historically associated with gastrointestinal (GI) adverse events (AEs). Colchicine has very low risk for AEs, even in patients with GI disorders; whereas, NSAIDS are contraindicated in patients with GI disorders, renal insufficiency, and heart failure. The monthly cost of treating 100 patients with Colcrys was $33,100 compared with $3000 for NSAIDs. However, hospitalization for GI complications (1.8%) and heart failure (1.9%) is common with NSAIDs and can increase the monthly cost of treating 100 patients with NSAIDs to $161,000, considering $15,000-20,000 per day of hospitalization. CONCLUSIONS Considering high costs associated with treating patients with gout, it seems prudent to choose the treatment with greatest benefit, lowest cost, and least risk. Despite higher cost per dose, colchicine appears to be more cost effective for management of gout flares than NSAIDs.

Abstract
OBJECTIVES Clinical trials of tumour necrosis factor antagonists have raised questions about the potential risk of certain serious adverse events (SAE). To assess the safety of adalimumab in rheumatoid arthritis (RA) over time and across five other immune-mediated inflammatory diseases and to compare adalimumab malignancy and mortality rates with data on the general population. METHODS This analysis included 19,041 patients exposed to adalimumab in 36 global clinical trials in RA, psoriatic arthritis (PsA), ankylosing spondylitis (AS), Crohn's disease (CD), psoriasis and juvenile idiopathic arthritis (JIA) to 15 April 2007. Events per 100 patient-years were calculated using SAE reported after the first dose to 70 days after the last dose. Standardised incidence rates were calculated for malignancies using national and state-specific databases. Standardised mortality rates (SMR) were calculated for each disease using data from the World Health Organization. RESULTS Cumulative rates of SAE of interest in RA have remained stable over time. Rates of SAE of interest for PsA, AS, CD, psoriasis and JIA were similar to or lower than rates for RA. Overall malignancy rates for adalimumab-treated patients were as expected for the general population. SMR across all six diseases indicated that no more deaths occurred with adalimumab than expected in the general population. CONCLUSIONS Based on 10 years of clinical trial experience across six diseases, this safety report and the established efficacy of adalimumab in these diseases provide the foundation for a better understanding of its benefit-risk profile.

Abstract
Objective To investigate the influence of age at symptom onset and length of followup on mortality in patients with recent-onset inflammatory polyarthritis (IP), and to examine predictors of mortality in relation to disease duration. Methods From 1990 to 1994, patients with recent-onset IP were registered with the Norfolk Arthritis Register (NOAR) and followed up prospectively. Standardized mortality ratios (SMRs) were calculated for all-cause and cardiovascular disease (CVD) mortality and for those who were younger than age 55 years at disease onset and for the first 5 and 10 years of followup. Cox proportional hazards models were developed to assess predictors of early and later mortality. Results Of 1,098 patients, 224 (20%) had died by the end of 2004. All-cause and CVD mortality were increased in rheumatoid factor (RF)–positive patients and in this subgroup, CVD mortality was increased at both early and later followup (SMR 5-year followup 1.93 [95% confidence interval 1.08–3.19]; SMR 10-year followup 2.00 [95% confidence interval 1.37–2.80]). CVD mortality was highest in seropositive patients <55 years of age at disease onset (SMR 5.58 [95% confidence interval 2.24–11.50]). In multivariate models, age at onset, male sex, RF positivity, Health Assessment Questionnaire score ≥1.5, and nodules were predictors of early and later mortality. Conclusion Patients with IP had higher rates of CVD mortality throughout the followup period studied, and this was highest in seropositive patients who were <55 years of age at symptom onset. This subgroup deserves particular attention in terms of disease and risk factor modification. Nodules were independent predictors of CVD mortality, suggesting that extraarticular/vascular inflammation identifies patients at particularly high CVD risk.

Abstract
OBJECTIVE To examine the role of the variants of the PTPN22 and HLA-DRB1 genes as predictors of mortality in inflammatory polyarthritis (IP) and rheumatoid arthritis (RA). METHODS Patients were recruited from a primary care-based inception cohort of patients with IP and were followed up prospectively. For patients who died, the cause and date of death was obtained. Cox proportional hazards regression models were used to assess the association of the HLA-DRB1 (including the shared epitope [SE]) and PTPN22 genes with the risk of death from all causes and from cardiovascular disease (CVD) and to assess the interactions between SE, smoking, and anti-cyclic citrullinated peptide (anti-CCP) status, adjusted by age at symptom onset and sex. RESULTS DNA samples were available from 1,022 IP patients. During followup, 751 of them (74%) satisfied the American College of Rheumatology 1987 criteria for RA, and 242 of them (24%) died. Carriage of 2 copies of SE alleles predicted death from all causes (hazard ratio [HR] 1.57 [95% confidence interval (95% CI) 1.1-2.2]) and from CVD (HR 1.68 [95% CI 1.1-2.7]). This effect was most marked for individuals with the HLA-DRB1*01/*04 combination. An interaction of smoking, SE alleles, and anti-CCP antibodies was observed and was associated with the greatest risk of death from CVD (HR 7.81 [95% CI 2.6-23.2]). No association of the PTPN22 gene with mortality was detected. CONCLUSION SE alleles, particularly compound heterozygotes, are associated with death from all causes and from CVD, independently of autoantibody status. However, the combination of SE, smoking, and anti-CCP antibodies is associated with a high risk of premature death in patients with IP and RA, which raises the possibility of a targeted strategy to prevent CVD in these patients.

Abstract
PURPOSE To estimate the net cardiovascular (CV) (coronary heart disease, stroke, congestive heart failure), and gastrointestinal (GI) (peptic ulcer complications) risk-benefit public health impact of the use of celecoxib compared to non-selective NSAIDs in the arthritis population. METHODS We applied discrete event simulation models to data from the US National Health Surveys, CV risk-prediction models from the Framingham Heart Study, and population-based studies. Models took into account the multifactorial effect of risk factors, comorbidity, and competing risk of mortality. We simulated the natural history of CV and GI disease in the U.S. arthritis population over 1 year, through the individual baseline cardiovascular and gastrointestinal risk profile. This model was modified with relative risks associated with the use of each treatment. The mean number of events was estimated for each end-point in each model: natural history, celecoxib, diclofenac, ibuprofen, naproxen. The number of events for celecoxib was compared with each NSAID. RESULTS The evaluation included 1% of the U.S. population with arthritis. Celecoxib, when applied to 100 000 patients over 1 year, resulted in 570 (range from sensitivity analysis: 440-691), 226 (124-313), and 746 (612-868) fewer ulcer complications than diclofenac, ibuprofen, and naproxen, respectively. There were 20 (16-25), 8 (4-12), and 27 (22-32) fewer deaths from ulcer complications, respectively. No increase in cardiovascular events or all cause mortality was observed for celecoxib versus the other individual NSAIDs. CONCLUSION Results from these simulations suggest a gastrointestinal benefit for celecoxib not offset by increased cardiovascular events or mortality. The methodology used here provides a risk-benefit assessment framework for evaluating the public heath impact of drugs.

Abstract
OBJECTIVE To investigate the predictive value of early functional disability in patients with inflammatory polyarthritis (IP), for all-cause and cardiovascular disease (CVD) mortality. METHODS 1010 subjects with new-onset IP from the Norfolk Arthritis Register were studied. All were seen at baseline and at 1 year. Health Assessment Questionnaire (HAQ) scores were obtained at both time points. Vital status at 10 years from registration was established through central records. Mortality (all-cause and CVD) per 1000 person-years were calculated by HAQ stratum (HAQ scores<1, 1-2 and>or=2). The predictive value of HAQ (per unit increase) at the two time points, adjusted for age at onset of symptom, sex and other factors found to predict mortality, was assessed using Cox regression models. The analysis was repeated for those who satisfied the 1987 American College of Rheumatology criteria for rheumatoid arthritis (RA) by 5 years. RESULTS By 10 years, 171 (16.9%) subjects had died. 89 deaths (52%) were attributed to CVD. Mortality was greatest in the highest HAQ group at both time points. Following adjustment for other predictors, HAQ score at year 1 remained a significant predictor of all-cause mortality (HR 1.46; 95% CI 1.15 to 1.85) and CVD mortality (HR 1.49; 95% CI 1.12 to 1.97). The predictive value of HAQ at year 1 was similar in the RA subgroup. CONCLUSIONS Our data show that at 1 year of follow-up, HAQ score is an important independent predictor of subsequent all-cause and CVD mortalities in people with IP and RA. Baseline HAQ scores are of less value.

Abstract
The unicompartmental knee arthroplasty continues to gain popularity as a viable treatment option for disease isolated to one compartment. It has been reported to provide decreased perioperative morbidity, faster recovery, and excellent long- term survival. We hypothesized that the unicompartmental knee arthroplasty is durable enough to benefit octogenarians, and may be a viable alternative to total knee arthroplasty as the definitive treatment of localized arthritis in this age group. From 1978 to 1990, 28 consecutive patients (38 knees) 80 years or older had unicompartmental knee arthroplasties. Knee Society knee and function scores improved at an average of 4 years followup (range, 2-9 years). Family members reported 90% patient satisfaction regarding expectations and desire to have the surgery again. The mean postoperative survival was 11.9 years, and only two of the 38 knees (5%) required surgical intervention. At final followup, 25 patients had died with all but one patient having the index unicompartmental knee arthroplasty in place and functioning well. Of the three living patients, one required surgery for femoral component fracture 10 years after the index procedure. The unicompartmental knee arthroplasty can be expected to provide reliable and durable results in certain octogenarians, and should be regarded as a definitive treatment option in appropriated selected patients of this age group.

Abstract
There have been few reports in the literature of total elbow arthroplasty extending beyond 10 to 15 years. We reviewed 40 patients (41 elbows) with a mean age of 56 years (19 to 83) who had undergone a Coonrad/Coonrad-Morrey elbow arthroplasty by one surgeon for various diagnoses between 1974 and 1994. Surgical selection excluded patients with previous elbow infection or who refused to accept a sedentary level of elbow activity postoperatively. Objective data were collected from charts, radiographs, clinical photographs and supplemented by the referring orthopaedic surgeons’ records and radiographs if health or distance prevented a patient from returning for final review. Subjective outcome was defined by patient satisfaction. Of the 41 elbows, 21 were functional between 10 and 14 years after operation, ten between 15 and 19 years and ten between 20 and 31 years. There were 14 complications and 13 revisions, but no cases of acute infection, or permanent removal of any implant.

Abstract
Given the increase in sow mortality in Danish pig herds over the last 10 years, we have investigated the causes of spontaneous death and killing of sows, especially those due to locomotive disorders. A total of 265 culled sows (93 spontaneously dead sows and 172 killed sows) from 10 different herds were sent for complete necropsy, and grouped according to primary diagnoses. From 35 of these sows, tissue for histological evaluation and samples for bacteriological cultivation were also collected, and secondary diagnoses and body condition were recorded. The main causes for killing were related to the locomotive system (72%), arthritis (24%) and fractures (16%) being the most frequent lesions. The main causes of spontaneous death were related to the gastrointestinal system and spleen (45%) and the reproductive system (24%). Arthrosis was a secondary diagnosis in 88% of the killed sows and in 92.5% of the spontaneously dead sows. Arcanobacterium pyogenes was the main cause of arthritis. The killed sows had significantly lower body condition compared with spontaneously dead sows. The first two parities and the time around farrowing were associated with the highest mortality in both groups. Hopefully, these observations can guide breeding units attempting to monitor, control and reduce sow mortality.

Abstract
OBJECTIVE To analyze US trends in deaths from arthritis and other rheumatic conditions (AORC). METHODS Multiple cause of death tapes from the National Center for Health Statistics from 1979 to 1998 were reviewed. Age, sex, and race-specific death rates were calculated. RESULTS During 1979-1998, the annual number of AORC deaths rose from 5537 to 9367. In 1979, the crude death rate from AORC was 2.46 per 100,000 population; by 1998, it was 3.48. Rates age-standardized to the year 2000 population were 2.75 and 3.51, respectively. Annual crude and age-standardized death rates were higher among women than men and higher among blacks than whites and increased for all groups over the 20 years. Death rates were dramatically higher with increasing age. Three categories of AORC accounted for almost 80% of deaths: diffuse connective tissue diseases (34%), other specified rheumatic conditions (23%), and rheumatoid arthritis (22%). CONCLUSION There are marked age, sex, and race-specific disparities in AORC death rates. AORC death rates may be underestimated because of (1) nonrecognition of inflammatory arthritis and (2) attribution of cause of death to conditions made more likely by arthritis, e.g., cardiovascular disease, or to complications from arthritis therapy. Further research into the causes of the disparities in death rates and the increase in death rates for men, women, blacks, and whites is necessary.

Abstract
This paper examines gender differences in life with and without six major diseases, including both mortal and morbid conditions. Disease prevalence and health behavior data are from the 1993-1995 National Health Interview Surveys for the United States. Vital registration data are the source of mortality rates used in computing life expectancy. The Sullivan method is used to estimate life lived with and without disease and risky behavior for men and women at various ages. Women live more years with each of the diseases examined, and, for arthritis, the extended years with disease are greatest. Women also live more years than men free of each of these diseases with the exception of arthritis. Gender differences in life without two health-risk behaviors are also discussed. Men spend more years of their lives overweight and have fewer years during which they see a doctor.

Abstract
OBJECTIVE To determine the degree and causes of any excess mortality observed during the early years of inflammatory polyarthritis (IP). METHODS Between 1990 and 1994, a total of 1,236 patients were registered with the Norfolk Arthritis Register, a primary care-based inception cohort. All patients were tracked on the National Health Service Central Register for notification of death. The vital status of each patient was determined as of December 31, 1999. Causes of death were coded according to the International Classification of Diseases, Ninth Revision. Expected death rates were calculated using annual death rates for the Norfolk population. Standardized mortality ratios (SMRs) were calculated for all IP patients and for the subgroups of patients who did and did not satisfy the American College of Rheumatology (ACR) 1987 criteria for rheumatoid arthritis (RA) at baseline, as well as for the subgroups who were and were not rheumatoid factor (RF) positive at baseline. RESULTS By December 31, 1999, 160 patients (13%; 79 women and 81 men) had died. The median duration of followup in the entire cohort was 6.9 years. Mortality rates were not significantly increased in the entire group of patients with IP or in the subgroup who met the ACR 1987 criteria for RA at baseline. In contrast, RF-positive patients had an increased rate of death from all causes (SMR in men 1.51, in women 1.41). Cardiovascular disease was the most common cause of death. The majority of the excess mortality in the RF-positive patients could be attributed to cardiovascular causes (SMR in men 1.34, in women 2.02). CONCLUSION Excess mortality in the early years of IP is confined to patients who are seropositive for RF. While excess cardiovascular mortality has been described in patients with established RA, this is the first report of premature death from heart disease in the early years of IP.

Abstract
A study of 562 Anatomic Graduated Component (AGC) total knee arthroplasties that were performed in 402 patients between November 1986 and September 1990 is reported. All patients had implantation with a cemented posterior cruciate-retaining design, with resurfacing of the patella using all polyethylene patella components. Mean age at surgery was 71 years (range 41-92 years). Patients were followed for a minimum of 10 years (range 10-14 years). Nine knees were lost to follow-up (1.4%). The mean Knee Society Score for pain and function were analyzed by Charnley categories: Category A -- 97 (pain) and 89 (function); Category B -- 91 (pain) and 84 (function); and Category C -- 89 (pain) and 62 (function). The survival analysis at 14 years was 97% with revision for any reason as the endpoint and the authors continue to utilize this implant system.

Abstract
Silica exposure has been associated with kidney disease and rheumatoid arthritis; an autoimmune mechanism has been proposed. Approximately 2 million people are occupationally exposed to silica in the United States, 100,000 at more than twice the National Institute for Occupational Safety and Health recommended exposure limit of 0.05 mg/m(3). We examined renal disease morbidity and mortality, as well as arthritis mortality, in a cohort of 4,626 silica-exposed workers in the industrial sand industry (an industry previously unstudied). We compared the cohort with the U.S. population and also conducted internal exposure-response analyses using a job-exposure matrix based on more than 4,000 industrial hygiene samples. We found excess mortality from acute renal disease [standardized mortality ratio (SMR) = 2.61, 95% confidence intervals (95% CIs) = 1.49--4.24; 16 deaths], chronic renal disease (SMR = 1.61, 95% CI = 1.13--2.22; 36 deaths), and arthritis (SMR = 4.36, 95% CI = 2.76--6.54; 23 deaths) on the basis of multiple-cause mortality data, which considered any mention of disease on a death certificate. Linking the cohort with the U.S. registry of end-stage renal disease for the years 1977-1996, we found an excess of end-stage renal disease incidence (standardized incidence ratio = 1.97, 95% CI = 1.25--2.96; 23 cases), which was highest for glomerulonephritis (standardized incidence ratio = 3.85, 95% CI = 1.55--7.93; 7 cases). We found increasing end-stage renal disease incidence with increasing cumulative exposure; standardized rate ratios by quartile of cumulative exposure were 1.00, 3.09, 5.22, and 7.79. A positive exposure-response trend was also observed for rheumatoid arthritis on the basis of death certificate data. These data represent the largest number of kidney disease cases analyzed to date in a cohort with well-defined silica exposure and suggest a causal link between silica and kidney disease. Excess risk of end-stage renal disease due to a lifetime of occupational exposure at currently recommended limits is estimated to be 14%, above a background end-stage renal disease risk of 2%.

Abstract
AIM To describe predictors of mortality in the 5 year follow up of the Melbourne Visual Impairment Project (VIP) cohort. METHODS The Melbourne VIP was a population based study of the distribution and determinants of age related eye disease in a cluster random sample of Melbourne residents aged 40 years and older. Baseline examinations were conducted between 1992 and 1994. In 1997, 5 year follow up examinations of the original cohort commenced. Causes of death were obtained from the National Death Index for all reported deaths. RESULTS Of the original 3271 participants, 231 (7.1%) were reported to have died in the intervening 5 years. Of the remaining 3040 participants eligible to return for follow up examinations, 2594 (85% of eligible) did participate, 51 (2%) had moved interstate or overseas, 83 (3%) could not be traced, and 312 (10%) refused to participate. Best corrected visual acuity <6/12 (OR=2.34) was associated with a significantly increased risk of mortality, as were increasing age (OR=1.09), male sex (OR=1.62), increased duration of cigarette smoking (OR=2.06 for smoking >30 years), increased duration of hypertension (OR=1.51 for duration >10 years), and arthritis (OR=1.42). CONCLUSIONS Even mild visual impairment increases the risk of death more than twofold. Further research is needed to determine why decreased visual acuity is associated with increased risk of mortality.

Abstract
UNLABELLED This paper is an integrated analysis of newspaper coverage, epidemiological rates, and recent social history of six prominent diseases. HYPOTHESES Newspaper coverage of a disease has three developmental stages (emergence, maturation, and decline & death). Trends in newspaper coverage of a disease reflect trends in its mortality, prevalence, and incidence. Magnitudes of newspaper coverage of diseases reflect their differential mortality rates. DATA Using the LEXIS-NEXIS news archive for major U.S. newspapers, we retrieve articles about cancer, heart disease, AIDS, diabetes, Alzheimer disease, and arthritis for the period 1977-1997. We also obtain mortality, prevalence, and incidence trends for the six diseases. RESULTS During the two decades, newspaper coverage emerges for AIDS and Alzheimer disease and is in the mature stage for the other diseases; declines begin for heart disease and AIDS. Trends in news coverage closely parallel mortality trends, and less consistently prevalence and incidence trends. Sharp downturns and upturns in mortality are mirrored in news volume. High-mortality diseases prompt both the most news coverage and the largest proportions of articles with death topics. CONCLUSION Newspaper coverage of diseases is responsive to their mortality levels and trends.

Abstract
MT1-MMP is a membrane-bound matrix metalloproteinase (MT-MMP) capable of mediating pericellular proteolysis of extracellular matrix components. MT1-MMP is therefore thought to be an important molecular tool for cellular remodeling of the surrounding matrix. To establish the biological role of this membrane proteinase we generated MT1-MMP-deficient mice by gene targeting. MT1-MMP deficiency causes craniofacial dysmorphism, arthritis, osteopenia, dwarfism, and fibrosis of soft tissues due to ablation of a collagenolytic activity that is essential for modeling of skeletal and extraskeletal connective tissues. Our findings demonstrate the pivotal function of MT1-MMP in connective tissue metabolism, and illustrate that modeling of the soft connective tissue matrix by resident cells is essential for the development and maintenance of the hard tissues of the skeleton.

Abstract
Erosive arthritis (EA) in systemic lupus erythematosus (SLE) can be debilitating and deforming with uncertain factors for risk, although antibodies to the A2 hnRNP core protein, known as anti-RA33, have been associated with EA. Two hundred patients under long-term follow-up for SLE were evaluated for EA and associated clinical and serological abnormalities. In addition, sera were tested in a masked fashion for anti-RA33 antibodies in a total of 60 patients: 10 with EA and 50 age-, sex- and ethnically matched controls. Ten of 200 (5%) patients with SLE, mainly non-white women, had EA. There were trends for increased renal involvement (P = 0.06), Sjögren's syndrome (P = 0.07) and Raynaud's phenomenon (P = 0.03) in patients with EA compared to those without EA. Rheumatoid factor (RF) was increased in patients with EA (P < 0.02), as were antibodies to double-stranded DNA (P < 0.05), Sm (P < 0.01) and La/SS-B (P < 0.001). Anti-RA33 antibodies were present in 70% with EA compared to 28% without EA (P < 0.05). RF correlated with anti-RA33 antibodies in patients with EA, but not with the presence of anti-RA33 alone. Thus, anti-RA33 antibodies may identify those patients with SLE who are at risk for EA, and an association with RF suggests a common immune response or pathological mechanism in autoimmune erosive joint disease.

Abstract
OBJECTIVE To review the diagnoses after 5 years in patients who were identified within 12 months of the onset of well established and undifferentiated connective tissue diseases (CTD); to examine death rates and disease remissions in these patients. METHODS This inception cohort of 410 patients was identified in 10 academic rheumatology practices. They had less than one year of signs and/or symptoms of CTD. Diagnoses of specific well established CTD were made using accepted diagnostic and classification criteria. The diagnoses after 5 years were determined. RESULTS Patients with well established CTD tended to remain with the original diagnosis. The progression of unexplained polyarthritis to rheumatoid arthritis occurred infrequently. Ten percent of patients with isolated Raynaud's phenomenon progressed to systemic sclerosis (SSc). The 5 year survival was over 90% in all diagnostic categories, with the exception of SSc, in which it was 64%. CONCLUSION Patients with a well established CTD usually continued with the same diagnosis. Patients with undifferentiated CTD tended to remain undifferentiated or to remit.

Abstract
BACKGROUND Mortality in patients with systemic lupus erythematosus (SLE) is often related to disease in particular organ systems. We examined the risks of mortality associated with 8 clinical manifestations of SLE and determined whether these risks differed among patients with different sociodemographic characteristics. METHODS Using life table analysis, we determined the associations of hemolytic anemia, leukopenia, thrombocytopenia, arthritis, serositis, nephritis, psychosis, and seizures with both all-cause mortality and SLE-related mortality in a cohort of 408 patients. RESULTS Over a median duration of follow-up of 11 years, 144 patients died; 78 deaths (54%) were SLE related. In univariate analyses, the presence of hemolytic anemia, serositis, nephritis, psychosis, and seizures was associated with greater all-cause mortality, while the presence of arthritis was protective. In multivariate analyses that controlled for patient demographic characteristics, nephritis (relative risk, 2.34) and seizures (relative risk, 1.77) were associated with poorer overall survival. Nephritis and seizures, along with thrombocytopenia, were also associated with greater SLE-related mortality, while leukopenia was protective. The risk of death in association with these clinical manifestations did not differ among patient age, sex, race, or socioeconomic subgroups. CONCLUSIONS The presence of nephritis and seizures each increased the risk of death in patients with SLE approximately 2-fold. Thrombocytopenia also increased the risk of SLE-related mortality, while leukopenia was protective.

Abstract
OBJECTIVE To investigate chronic arthritis and rheumatoid factor (RF) for their prediction of premature total and cardiovascular mortality. METHODS In 1978-80, a representative population sample of 8000 Finns aged 30 or more was invited to participate in a comprehensive health examination; 90% complied. Arthritis was diagnosed on the basis of medical history, symptoms, and physical examination. Serum RF was determined by the sensitised sheep cell agglutination test. RESULTS By the end of 1992 1597 of the subjects had died from all causes, including 876 deaths from cardiovascular diseases. When adjusted for age, gender and smoking, the relative risk of persons with RF positive arthritis dying from any cause was 1.61 (95% confidence interval (CI) 1.03 to 2.51); RF negative non-erosive arthritis was not associated with mortality (relative risk 1.03; 95% CI 0.72 to 1.49). In the absence of arthritis, 'false positive' RF titres > or = 128 predicted cardiovascular deaths with a relative risk of 1.74 (95% CI 1.06 to 2.86). CONCLUSION Both RF positive arthritis and false positive RF reactions predict mortality, but through different disease patterns.

Abstract
Subsets were analyzed of respondents from the Epidemiological Follow-up to the National Health and Nutrition Examination Survey I (NHANES I) who (1) answered a general arthritis question reflecting whether a doctor told the respondent that she or he had arthritis, (2) answered seven pain, swelling, and stiffness questions, and (3) had radiographs of knees and hips assessed for osteoarthritis at the time of the initial survey during the early 1970s. Data for the follow-up were collected between 1982 and 1984 and included 1,491 fatalities in the largest subsample analyzed here. The dependent variable was months of survival after the initial interview. No distinction was drawn between rheumatoid arthritis versus osteoarthritis. The NHANES I contained only limited information on rheumatoid arthritis versus osteoarthritis. Additional covariates included age, age squared, education, race, marital status, diastolic blood pressure, and body mass. After adjusting for age, no statistically significant associations emerged between answers to the general arthritis questions or any of the seven pain questions on the one hand, and mortality on the other. Similar statistically insignificant results were found when the association between radiographic diagnoses of osteoarthritis in the hips and months of survival was considered after adjusting for age. These statistically insignificant results persisted in repeated testing, which alternately included and excluded a number of covariates, and in separate subsamples of women, men, and persons older and younger than age 50. Some evidence was found, however, for a negative, statistically significant association between radiographic knee diagnoses of osteoarthritis and survival, especially among women, even after adjusting for covariates. These mixed results (1) do not discredit findings elsewhere suggesting that rheumatoid arthritis is associated with early death, since it is likely that the great majority of respondents answering in the affirmative to the general arthritis or seven pain questions in the NHANES I had osteoarthritis, and (2) suggest that future surveys should make greater attempts to distinguish between rheumatoid arthritis and osteoarthritis.

Abstract
OBJECTIVE A model adjusting for reductions in quality and quantity of life was developed to estimate the population health impact of musculoskeletal diseases. METHODS Using arthritis as the prototype, prevalence, mortality, and severity data from a variety of sources were combined to model a hypothetical cohort of 1,000 individuals through life. Quality adjusted life years and population health expectancy were calculated for those with arthritis and compared to the general population. RESULTS Without adjusting for quality of life, a cohort of 1,000 women and 1,000 men at age 15 years could expect 65,010 and 58,735 life years, respectively. Adjusting for quality of life, women with arthritis could expect 61,719 life years, and men 57,123 life years. The unadjusted population health expectancy was 65.0 for girls and 58.7 for boys (at age 15 years). Adjusting for quality of life, the population health expectancies were 61.7 and 57.1, years for women and men, respectively. CONCLUSION Using this model, the typical adult woman with arthritis can expect to lose 3.3 healthy years of life, and a man, 1.6 healthy years of life. Overall, the model provided a general methodology for determining the population health impact of musculoskeletal diseases. In addition, it is hoped that the methodology will stimulate further research into this area, raise awareness about the uses and limitations of currently available data, and provide a useful model for monitoring the impact of interventions.

Abstract
The workshop was convened to develop quantitative estimates of the incidence of progressional musculoskeletal diseases in order to estimate the population health impact of arthritis. Estimates were developed for (a) the prevalence of arthritis, (b) a weighting strategy to adjust for the quality of life for the range of health states associated with arthritis, and (c) transition probabilities to represent the likelihood of disease onset and progression through the range of possible health states. A simulation "game" was designed to follow the progression of a cohort of 200 healthy persons or persons with arthritis, creating the basis for the estimation of transition probabilities and thus generating simulated longitudinal data that allow calculation of the quantitative estimate of the burden of illness from musculoskeletal diseases within the Canadian population.

Abstract
We used the Longitudinal Study on Aging, a national study of community-dwelling elderly people, to 1) estimate the number of elderly persons with arthritis, with and without other chronic conditions, living in the community in 1984, who reported limitations in physical activities, activities of daily living (ADL), and instrumental activities of daily living (IADL); 2) enumerate the population of the elderly with arthritis who were receiving help or paid help with ADL or IADL; and 3) estimate the number of such persons experiencing a change in health status in the ensuing 2 years. In 1984, 14% of all 15.6 million community-dwelling elderly people had arthritis and no other chronic conditions; 41% had arthritis concurrently with other chronic conditions. Of the former group, 66% experienced limitations in physical activities, but only approximately 25% reported limitations in ADL or IADL in 1984. Among the group with arthritis and other chronic conditions, 82% were limited in at least 1 physical activity, and 41% were limited in ADL. With the passage of 2 years, 2% of elderly persons with arthritis and no other conditions had entered a nursing home, 7% had died, and the percentage reporting no limitation declined significantly. Among elderly persons with arthritis and other conditions, 4% entered a nursing home, 12% died, and the rates of all forms of limitation increased. It is essential to gather data such as these, on the prevalence and incidence of limitation among the elderly with arthritis, to ensure adequate long-term care services for an increasing aged population.

Abstract
In the Rancho Bernardo, California population of older adults, the age-adjusted prevalence rate of self-reported arthritis was higher in women than men for all types combined (38.6 vs. 22.3%, p less than 0.05), and for osteoarthritis (18.1 vs 12.9%). Men and women with osteoarthritis and disabling arthritis were significantly more likely to report co-morbid conditions. Women with osteoarthritis were significantly less likely to drink alcohol and more likely to be taking estrogen replacement therapy. At 15 years of follow up, mortality rates were not significantly increased in men or women with arthritis or osteoarthritis compared to those without arthritis.

Abstract
The incidence and causes of polyarthritis in sucking pigs were studied in herds with 2,936 litters during a 2-year period. Among pigs more than 3 days old, the average morbidity rate was 3.3 per cent and the mortality rate amounted to 1.5 per cent (Table I). Among herds the morbidity ranged from 0.9 to 7.0 per cent and the mortality due to polyarthritis from 0.5 to 2.8 per cent. The incidences of polyarthritis were higher in the progeny of gilts than in the progeny of sows of other age groups (Table II). No consistens correlation between litter size at birth and the mortality rate due to polyarthritis was found (Table III). Cases of polyarthritis were observed in 17.8 per cent of the examined litters. Death due to polyarthritis occurred in 10.8 per cent of the litters (Table I); 67.3 per cent of the fatal cases occurred sporadically with only one pig lost per litter (Table IV). The mortality due to polyarthritis appeared to be higher in male pigs (Table V). An analysis of some possible contributory factors showed that the frequency of polyarthritis was adversely affected by new introduction of female breeding stock, clipping of the canine teeth and tail docking in the new-born, and by occurrence of skin diseases in individual piglets (Table VI, IX & XII). No obvious relation was found with such factors as: season of the year, sow's health condition, herd size (Table I), or hygiene level in the individual herds (Table VIII). Death due to polyarthritis occurred most frequently in pigs 2--4 weeks of age (Table X). The pathological lesions, which varied according to the duration of the inflammation and to the aetiology, are described. Arthritis was most frequently observed in the larger limb joints, although every joint may be affected (Table XI). In the majority of the cases a meningoencephalitis was present. A survey of other concomitant, complicating or possible predisposing lesions are presented (Table XII). The bacteriological examination of joints and other organs Table XIII) showed that haemolytic streptococci by far dominated as causative organism. Staphylococci species and E. coli were isolated from affected joints in 6.4 per cent and 4.3 per cent of the pigs, respectively. C. pyogenes and E. rhusiopathiae were rarely encountered in these sucking pigs with polyarthritis. Aspects of the epidemiology and pathogenesis are discussed in regard of minimizing the losses due to polyarthritis/meningitis in sucking pigs.
