Abstract
INTRODUCTION Skin popping (SP) is a popular technique for drug misuse, for its ease of administration and longer duration of effect. Skin infection is a well-described sequela of SP, but less is known about the more extreme sequelae of this practice. METHODS Five patients who engaged in SP requiring major surgical intervention were identified on case review to highlight extreme diseases resulting from the practice of SP. Each patient reported using heroin or tested positive for opioid on admission. Each patient admitted to practicing SP or maintained a shooter's patch. A multidisciplinary approach was employed to care for the patient. Members of the departments of medicine, surgery, nursing, addiction medicine, infectious disease, rehabilitation, and social work collaborated in the complex management of each patient. RESULTS Five patients presented to Rush University Medical Center between 2017 and 2019 for complications of SP. All 5 patients were actively using nonprescription opioids; 2 were concurrently undergoing treatment for opioid use disorder. Recurrent SP led to failed surgical treatment in all but 1 patient. Surgical outcome was directly related to recidivism. CONCLUSION The successful surgical management of severe sequelae of SP depends upon the successful management of the patient's addiction. Multidisciplinary care by surgical, medical, psychiatric, addiction, nursing, rehabilitation, and social work specialists is necessary to achieve a successful outcome. Based on this experience, the author's institution no longer offers nonurgent closure procedures to patients whose addiction is not well controlled.

Cause-Specific Mortality Trends Following Total Hip and Knee Arthroplasty. J Arthroplasty 2017; 32:1292-1297. [PMID: 27866950 PMCID: PMC5362336 DOI: 10.1016/j.arth.2016.10.009] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2016] [Revised: 09/13/2016] [Accepted: 10/09/2016] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND While studies have demonstrated that mortality after total hip (THA) and total knee (TKA) arthroplasty is better than the general population, the causes of death are not well established. We evaluated cause-specific mortality after THA and TKA. METHODS The study included population-based cohorts of patients who underwent THA (N = 2019) and TKA (N = 2259) between 1969 and 2008. Causes of death were classified using the International Classification of Diseases 9th and 10th editions. Cause-specific standardized mortality ratios (SMR) and 95% confidence intervals (CI) were calculated by comparing observed and expected mortality. Expected mortality was derived from mortality rates in the United States white population of similar calendar year, age, and sex characteristics. RESULTS All-cause mortality was lower than expected following both THA and TKA. However, there was excess mortality due to mental diseases such as dementia following both THA (SMR 1.40, 95% CI 1.08, 1.80) and TKA (SMR 1.49, 95% CI 1.19, 1.85). There was also excess mortality from inflammatory musculoskeletal diseases in THA (SMR 3.50, 95% CI 2.11, 5.46) and TKA (SMR 4.85, 95% CI 3.29, 6.88). When the cohorts were restricted to patients with osteoarthritis as the surgical indication, the excess risk of death from mental diseases still persisted in THA (SMR 1.36, 95% CI 1.02, 1.78) and TKA (SMR 1.52, 95% CI 1.20, 1.91). CONCLUSION THA and TKA patients experience a higher risk of death from mental and inflammatory musculoskeletal diseases. These findings warrant further research to identify drivers of mortality and prevention strategies in arthroplasty patients.

Abstract
Psoriatic arthritis (PsA) is a systemic inflammatory condition featuring polyarthritis associated with psoriasis. Apart from clinical indicators, few biomarkers exist to aid in the diagnosis and management of PsA. We hypothesized that whole blood gene expression profiling would provide new diagnostic markers and/or insights into pathogenesis of the disease. We compared whole blood gene expression profiles in PsA patients and in age-matched controls. We identified 310 differentially expressed genes, the majority of which are upregulated in PsA patients. The PsA expression profile does not significantly overlap with profiles derived from patients with rheumatoid arthritis or systemic lupus erythematosus. Logistic regression identified two lymphocyte-specific genes (zinc-finger protein 395 and phosphoinositide-3-kinase 2B) that discriminate PsA patients from normal controls. In addition, a highly coregulated cluster of overexpressed genes implicated in protein kinase A regulation strongly correlates with erythrocyte sedimentation rate. Other clusters of coregulated, yet suppressed genes in PsA patient blood include molecules involved in T-cell signaling. Finally, differentially expressed genes in PsA fall into diverse functional categories, but many downregulated genes belong to a CD40 signaling pathway. Together, the data suggest that gene expression profiles of PsA patient blood contain candidate novel disease markers and clues to pathogenesis.

Abstract
OBJECTIVE To determine the natural history of hip joint disease in psoriatic arthritis (PsA) and identify clinical risk factors for its early identification. PATIENTS AND METHODS 504 patients with PsA according to ESSG criteria were studied. Mean follow up was 5.7 years (range <1-45). Mean age at onset of psoriasis was 32 years and of PsA, 39 years. The most common pattern of PsA at onset was oligoarticular (49%) and at the latest examination, polyarticular (65%). Sacroiliitis or spondylitis was diagnosed in 94 (18.7%) patients. RESULTS 32 (6.3%) patients developed psoriatic hip arthropathy, and of these, 26 (81%) also had sacroiliitis or spondylitis. In 7/17 (41%) patients the hip became affected within 1 year after the onset of PsA. Hip disease occurred more often in younger patients. Sex, pattern of peripheral arthritis, duration of psoriasis before arthritis affected the distal interphalangeal joints, dactylitis, or enthesitis were not associated with the risk of hip disease. Seventeen patients were followed up and nine required hip arthroplasty. Sixteen (50%) first had arthroplasty within 5 years after the onset of hip pain. CONCLUSIONS Psoriatic hip arthropathy occurs infrequently in PsA and is associated with earlier onset of arthritis and psoriatic spondylitis. Bilateral hip involvement and rapid progression to hip arthroplasty are common.

Abstract
OBJECTIVE To guide primary care physicians regarding the diagnosis and treatment of poststreptococcal reactive arthritis (PSReA) in adults. PATIENTS AND METHODS We retrospectively reviewed an indexed database of all patients evaluated or hospitalized between 1976 and 1998 at Mayo Clinic Rochester and identified 35 patients with the diagnosis of reactive streptococcal arthritis, arthralgia, or arthritides. Twenty-nine patients with the diagnosis of acute rheumatic fever (ARF), septic streptococcal arthritis, or nonspecific reactive arthritis were excluded. RESULTS PSReA was confirmed in 6 adults (3 women, 3 men; age range, 25-66 years). All patients were symptomatic with polyarthritis and oligoarthritis disproportionate to the objective findings on physical examination. Although all patients had negative throat cultures at the onset of arthritis, increased titers of anti-DNase B and antistreptolysin O confirmed recent streptococcal infection. Antecedent events included pharyngitis in 3 patients (who had received a minimum of a 10-day course of penicillin) and toxic shock syndrome in 1 patient. The latency of onset of arthritis ranged from 4 days to 6 weeks. The arthritic symptoms had a protracted course beyond the typical maximum of 3 weeks described for ARF. Treatment with aspirin did not provide symptomatic relief in any of the patients, whereas the response to therapy with nonsteroidal anti-inflammatory drugs (NSAIDs) was at least partial in all cases. Symptomatic relief occurred in 1 patient who received indomethacin and in 1 patient treated with prednisone. Penicillin prophylaxis was recommended in 1 patient. CONCLUSION PSReA should be included in the differential diagnosis of all adult patients presenting with arthritis. Treatment strategies include aspirin, other NSAIDs, and corticosteroids. In adult patients with PSReA, there is no evidence to support the use of penicillin prophylaxis at this time.

Abstract
OBJECTIVE To describe trends in systemic lupus erythematosus (SLE) incidence and mortality over the past 4 decades. METHODS Using the Rochester Epidemiology Project resources, medical records were screened to identify all Rochester, Minnesota residents with any SLE-associated diagnoses, discoid lupus, positivity for antinuclear antibodies, and/or false-positive syphilis test results determined between January 1, 1980 and December 31, 1992. Medical records were then reviewed using a pretested data collection form in order to identify cases of SLE according to the American College of Rheumatology 1982 revised criteria for SLE. Drug-induced cases were excluded. All identified SLE patients were followed up until death, migration from the county, or October 1, 1997. These data were combined with similar data from the same community obtained between 1950 and 1979, and trends in the SLE incidence and mortality over time were calculated. RESULTS Of the 430 medical records reviewed, 48 newly diagnosed cases of SLE (42 women and 6 men) were identified between 1980 and 1992. The average incidence rate (age- and sex-adjusted to the 1970 US white population) was 5.56 per 100,000 (95% confidence interval [95% CI] 3.93-7.19), compared with an incidence of 1.51 (95% CI 0.85-2.17) in the 1950-1979 cohort. The age- and sex-adjusted prevalence rate as of January 1, 1993 was approximately 1.22 per 1,000 (95% CI 0.97-1.47). Survival among SLE patients was significantly worse than in the general population (P = 0.017 compared with the 1980-1992 cohort, and P < 0.0001 compared with the 1950-1979 cohort, by log-rank test). Cox proportional hazards modeling demonstrated a statistically significant improvement in the survival rate over time (P = 0.035). CONCLUSION Over the past 4 decades, the incidence of SLE has nearly tripled, and there has been a statistically significant improvement in survival. These findings are likely due to a combination of improved recognition of mild disease and better approaches to therapy.

Abstract
OBJECTIVE We conducted an open observational study to assess the short and longterm effect of single local glucocorticosteroid injection for trochanteric bursitis. METHODS 75 patient diagnosed with trochanteric bursitis based on clinical criteria were injected; 20, 32, and 22 patients each received 6, 12, and 24 mg betamethasone, respectively, mixed with 4 cm3 of 1% lidocaine. A standardized baseline questionnaire was administered to assess the severity and functional limitation due to trochanteric pain, including the visual analog scale for pain. Patients were followed at Weeks 1, 6, and 26 to determine their response to treatment. RESULTS 77.1, 68.8, 61.3% of responding patients reported improvement in pain at Week 1, 6, and 26, respectively. Patients receiving higher doses of betamethasone were more likely to experience pain relief (p < 0.0123). CONCLUSION Corticosteroid and lidocaine injection for trochanteric bursitis is an effective therapy with prolonged benefit.

Abstract
OBJECTIVE To review common rheumatologic disorders that affect elderly patients and emphasize the unique diagnostic and therapeutic challenges inherent in the management of rheumatologic diseases in this age-group. DESIGN We summarize our approach to treatment and management of specific rheumatologic problems in geriatric patients and discuss pertinent studies from the literature. RESULTS Among the spectrum of rheumatologic disorders frequently encountered in the elderly population are polymyalgia rheumatica, fibromyalgia, giant cell arteritis, crystalline arthropathies (gout and pseudogout), and degenerative joint disease. The initial manifestations of these rheumatologic diseases in elderly patients may differ from the typical findings in younger patients. Geriatric patients may have nonspecific complaints, a decline in physical function, or even confusion. Because of physiologic changes associated with aging and a decrease in functional reserves, elderly patients are susceptible to adverse effects of pharmacologic therapy (including nonsteroidal anti-inflammatory medications, corticosteroids, narcotic analgesics, allopurinol, and colchicine). Clinicians should be alert for such problems as hepatotoxicity and occult gastrointestinal blood loss. Comorbid conditions such as cardiovascular disease and cognitive impairment may complicate management strategies and may limit the goals of both surgical intervention and rehabilitation programs in elderly patients. CONCLUSION Rheumatologic disorders in geriatric patients pose special challenges to primary-care physicians. In the selection of optimal pharmacologic and nonpharmacologic therapeutic modalities, clinicians should focus on maintaining or improving the patient's quality of life and level of independent function.

Abstract
OBJECTIVE To assess the risk of fractures among patients with ankylosing spondylitis (AS). METHODS A population based cohort study compared fracture incidence in an inception cohort of 158 Rochester, Minnesota residents newly diagnosed with AS between 1935 and 1989 with expected rates from the same community. RESULTS In 2,398 person-years of observation, there was no increase in the risk of limb fractures, but there was a pronounced increase in the risk of thoracolumbar compression fractures (standardized morbidity ratio = 7.6; 95% CI, 4.3-12.6) among those with AS. CONCLUSION These data point to the importance of measures aimed at maintaining axial skeletal status in patients with AS.

Abstract
OBJECTIVE To determine trends in the incidence and clinical presentation of ankylosing spondylitis first diagnosed between 1935 and 1989 among residents of Rochester, Minnesota, and in the survival of the patients. METHODS Population-based descriptive study. RESULTS The overall age- and sex-adjusted incidence rate was 7.3 per 100,000 person-years (95% confidence interval 6.1-8.4). The rate tended to decline between 1935 and 1989, but there was little change in the age at symptom onset or diagnosis over the 55-year study period. Overall survival was not decreased up to 28 years following diagnosis. CONCLUSION These data indicate that there is a constancy in the epidemiologic characteristics of ankylosing spondylitis and suggest that previously study results indicating changes may have been due to biases in patient selection and study design.

Abstract
Circulating lupus anticoagulant (LA) is associated with thrombosis in large and small vessels. To determine how often the presence of LA is associated with thrombosis within the renal microcirculation, 33 patients with systemic lupus erythematosus (SLE), renal dysfunction, and LA were identified over a 25-year period (LA group) and 32 patients with renal SLE but with normal gross coagulation screen were matched for age, sex, and biopsy timing (C group). Prevalences of serositis, neuropsychiatric illness, leukopenia, thrombocytopenia, hemolysis, anti-DS-DNA elevation, and complement reduction were similar. Arthritis was less and biologic false-positive (BFP) syphilis serology more common in LA. More LA patients had thrombotic events (LA 39% v C 13%; P = 0.014); bleeding episodes, including postbiopsy, were similar. At biopsy, hypertension (LA 55%, C 41%), serum creatinine (mean +/- SD: LA 186 +/- 168 mumol/L [2.1 +/- 1.9 mg/dL] v C 150 +/- 168 mumol/L [1.7 +/- 1.9 mg/dL]) and proteinuria (LA 2.6 +/- 3.1 g/24 h v C 3.1 +/- 2.7) were similar. Lesions by World Health Organization (WHO) class, activity, and chronicity indices, as well as immunofluorescence (IF) and electron microscopy (EM) findings, were not significantly different. Occlusive glomerular, arteriolar, and arterial fibrin thrombi, along with varying degrees of renal thrombotic microangiopathy, were seen in five of 33 patients with LA, but zero of 32 C patients (P = 0.053); three of these five patients died soon after biopsy. Overall, mortality was not different between LA and C. We conclude that the majority of patients with SLE, renal dysfunction, and LA exhibit renal morphologic findings indistinguishable from patients without LA. However, a significant minority of LA patients have thrombotic microangiopathy in their biopsy, which is accompanied by a worse prognosis.

Abstract
This population-based study was carried out using the medical records linkage data resource for the population of Rochester, Minn, at Mayo Clinic. There were 132 newly diagnosed cases of psoriasis identified during a 4-year period (1980 through 1983); 88% of the cases had been seen and diagnosed by a dermatologist. The overall crude incidence rate was 57.6 per 100,000 population; for men and women, the rates were 54.4 and 60.2, respectively. The overall sex- and age-adjusted (1980 US white population) incidence rate was 60.4 per 100,000 person-years. The highest rate of occurrence (112.6) was in the 60- to 69-year-old age group. Most of the cases of psoriasis diagnosed in this study (58%) were mild, and the patients had psoriatic lesions on less than 10% of their body. There are no other published incidence rates for this condition with which to make comparisons.

Abstract
Total knee arthroplasty (TKA) is being used increasingly for the management of chronic arthritis of the knee. In this report, we review the frequency of application of TKA in the population of Olmsted County, Minnesota, from 1971 through 1986. The utilization rate of TKA increased from 20.5 per 100,000 person-years for 1971 through 1974 to 60.8 per 100,000 for 1983 through 1986. Although rates were higher in women, they increased with advancing age in both sexes. Rates between the urban and rural populations of Olmsted County did not differ. The two most common underlying diseases that necessitated TKA were osteoarthritis and rheumatoid arthritis; they were the cause of more than 90% of all operations. By extrapolating the rates of TKA in Olmsted County to the total 1986 US population, we estimate a need for at least 143,000 TKAs annually at a direct cost of more than $2.3 billion each year.

Abstract
We identified all residents of Rochester, Minnesota, who sought medical assistance for the first time in 1985 because of symptomatic osteoarthritis of the hip or knee that was unrelated to a specific disease. Of these residents, 98 (59 women and 39 men) had 122 symptomatic joints (95 knees and 27 hips), for age- and sex-adjusted incidence rates of 205 new patients and 255 newly affected joints per 100,000 person-years. The incidence of osteoarthritis of the hip was greater in women than in men, whereas the sex ratio for occurrence of osteoarthritis of the knee approached unity. Rates at both sites increased steadily with aging in men but plateaued after the menopause in women; similar patterns were seen whether or not grade 1 disease was included. Projected nationally, these first population-based data indicate that as many as approximately half a million new symptomatic cases of idiopathic osteoarthritis of the knee and hip may arise annually in the white population of the United States. With increasing longevity, osteoarthritis may exact an even greater toll in the future.

Abstract
The epidemiology of vasculitic syndromes encompasses a broad spectrum of diverse clinical syndromes. Almost all lack identified etiologic agents, and their clinical characteristics are determined predominantly by the size of the involved vessel and the end organs damaged. With the exception of giant cell arteritis/polymyalgia rheumatica in the elderly, and Henoch-Schönlein purpura and Kawasaki disease in the pediatric population, the vasculitic syndromes are infrequently observed diseases.

Abstract
We reviewed the clinical and laboratory features of 81 patients who had trigeminal sensory neuropathy (TSN) and a connective tissue disease (CTD). The neuropathy developed before the symptoms of CTD in 6/81 patients (7%), and in 38/81 patients (47%) TSN and CTD were diagnosed concurrently. The most frequently associated CTDs were undifferentiated connective tissue disease (38/81, 47%), mixed connective tissue disease (21/81, 26%), and scleroderma (15/81, 19%). Of 66 patients followed for more than 1 year (median, 5 years; range, 1 to 26 years), 8/66 patients (12%) had mild improvement and 2/66 (3%) had marked improvement of numbness; no patient had complete return of sensation. The facial numbness was frequently associated with moderate to severe facial pain that was usually resistant to pharmacologic therapy. None of the patients developed clinical or laboratory evidence of systemic vasculitis. The etiology of this cranial sensory neuropathy remains obscure.

Abstract
Relapsing polychondritis is a systemic disease of unknown etiology with predominate manifestations of multiorgan cartilaginous inflammation. Although relapsing polychondritis occurs predominantly as a separately defined clinical complex, a significant number of patients may suffer from another rheumatic disease. Vasculitic syndromes are the most commonly observed disorders associated with relapsing polychondritis.

Abstract
The first population-based incident case-control study of temporal arteritis (TA) in the US was conducted using the unique data resources of the Rochester Epidemiology Project. During the period 1950-1985, 88 newly diagnosed cases of biopsy-proven TA were identified among residents of Olmsted County, Minnesota. Cases were each matched to four Olmsted County community controls on age, sex and duration of community medical record. Odds ratios (OR) were calculated for marital status, education, Quetelet index, pregnancy, age at menopause, thyroid disease, diabetes, smoking, hypertension, angina, myocardial infarction, peripheral vascular disease, and stroke. Multivariable conditional logistic regression analysis identified statistically significant adjusted OR for smoking (2.3, 95% CI = 1.3-4.1). Elevated ORs which were not statistically significant were noted for angina, myocardial infarction, and peripheral vascular disease. These data suggest that TA and arteriosclerosis may share a common causal pathway. Alternatively, histopathological misclassification of temporal artery biopsies may have resulted in the observed association. Due to the limited power of this population-based study, multicentre collaboration should be encouraged to more precisely define the epidemiology of TA.

Abstract
We describe four cases, each with a distinct rheumatologic presentation. Three had lymphoma, and the fourth, though initially suggestive of lymphoma, had a tuberculous infection. Clinicians should be alert for diseases masquerading as diverse clinical syndromes. It is important to establish rheumatic, lymphoproliferative, or infectious etiology because of major differences in therapeutic and prognostic implications.

Abstract
We investigated the effects of prospectively identified factors on the duration of hospital stay and part A charges in 240 hospitalizations (of 230 patients) for the diagnosis-related group "medical back problems" (DRG 243) at a tertiary-care institution in 1985 to determine whether heterogeneity existed within this reimbursement category. We confirmed our initial postulates that nonosteoporotic fractures and neck problems, as well as hospitalizations primarily for myelography after outpatient neurologic evaluation, had considerably different economic outcomes and thus excluded these categories from further analysis. Statistical analysis (forward stepwise regression) of the remaining 132 patients who had "general medical back problems" showed that increasing age, associated osteoporosis, and therapeutic injections best explained variation in the natural logarithm of duration of stay (R2 = 0.16). Total number of diagnoses, spondylosis, associated osteoporosis, age, therapeutic injections, and performance of special procedures best explained the variation in the logarithm of part A charges (R2 = 0.29). The ability to identify factors within a specified category that affect the duration of hospitalization and part A charges jeopardizes the fairness of prospective payment, and we believe that DRG 243 should be adjusted for age, comorbidity, and readily identifiable clinical syndromes that have disparate economic consequences. Because of poorly substantiated efficacy and a significant association with longer hospital stays and higher part A charges, clinicians should review the use of therapeutic injections for medical back problems. Analysis of case-mix such as ours should be helpful in promoting efficient practice and ensuring the fairness of any reimbursement system.

Ninety-four Olmsted County, Minnesota residents with temporal arteritis (TA) initially diagnosed between 1950 and 1985 (incidence cohort) were identified. The age- and sex-adjusted incidence of TA per 100,000 population age 50 years or older was 17.0 (95% confidence interval [CI] 13.6-20.5), with a marked increase in incidence with age and a threefold greater incidence in women (23.4, 95% CI 18.2-28.7) than in men (7.4, 95% CI 3.7-11.0). The previously described secular increase in TA incidence in Olmsted County women continued from 1970 through 1985, while TA incidence in men declined in this latter time period. Although the frequency of classic clinical manifestations of TA declined over time, the percentage of patients undergoing biopsy who have positive specimens remained relatively constant (women 41%, men 26%). The incidence rate of temporal artery biopsy also increased for women during this period, but declined for men, suggesting that the differing trends in TA incidence by sex may be partially attributable to a detection bias. Future research in TA etiology and epidemiology should focus on possible causal factors linked to the differential TA incidence by sex.

Abstract
The clinical course of 52 cases with eosinophilic fasciitis observed at the Mayo Clinic has been described. Cutaneous changes included pitting edema, peau d'orange, and induration, and may affect virtually any body surface area. In addition, localized morphea was present in 15 cases. Arthritis was observed in 21 patients; 29 patients had flexion contractures and 12 had carpal tunnel syndrome. Associated hematologic diseases were found in five patients; thrombocytopenia in two, myeloproliferative disorder in one, myelomonocytic leukemia in one, and chronic lymphocytic leukemia in one. Peripheral blood eosinophilia was noted in 33 of 52 patients, hypergammaglobulinemia was noted in 17 of 49, and elevated sedimentation rate was noted in 15 of 52. Nonspecific EMG changes were seen in 11 of 15 patients. None had clinical involvement of the kidneys, lungs, or heart. No significant association between any HLA-A, -B, or -DR and eosinophilic fasciitis was seen. Prednisone and hydroxychloroquine seemed equally beneficial in treatment; however, some cases showed spontaneous recovery, making evaluation of therapeutic efficacy difficult. Relapses occurred in some cases.

Abstract
Thromboangiitis obliterans (Buerger's disease) is a nonatherosclerotic, inflammatory, occlusive vascular disease occurring almost exclusively in young male smokers. It involves principally medium sized and small arteries and veins of the lower and upper extremities, and only rarely the visceral and cerebral blood vessels. Buerger's disease of the temporal arteries, unassociated with the involvement of blood vessels of either the upper or lower extremities has not been previously reported. Three such cases, clinically mimicking the classic (giant cell) temporal arteritis of the elderly, are described. This unusual arterial lesion also bears some resemblance to subcutaneous angiolymphoid hyperplasia with eosinophilia (Kimura's disease).

Abstract
The incidence of Reiter's syndrome in a predominantly white, community-based population is reported. The age-adjusted annual incidence rate for males younger than age 50 was 3.5 per 100,000. No female cases were identified. Over time, a greater proportion of cases have been identified among younger males. In 63% of the patients, either a prolonged or relapsing disease course occurred.

Abstract
Forty-three prosthetic hip replacements (twenty-nine conventional total hip replacements and fourteen bipolar endoprosthetic replacements) were implanted between January 1971 and June 1982 in thirty-one patients who had systemic lupus erythematosus. All but four patients had stage-III or IV osteonecrosis of the femoral head. The median age at operation was forty-three years, and the median length of follow-up was fifty-seven months. Ratings were good or excellent for all but three total hip arthroplasties at a mean of sixty-six months of follow-up. Complications included delayed wound-healing (in approximately 15 per cent) and superficial wound infection (in approximately 10 per cent). The occurrence of these complications could not be correlated with the use of corticosteroids at the time of the operation. Twenty-five per cent of the patients, who were a mean of forty-three years old at operation, died less than five years postoperatively from complications related to systemic lupus erythematosus. Conclusions regarding the systemic effects of hip arthroplasty in patients with systemic lupus erythematosus could not be drawn on the basis of this study. Total hip arthroplasty uniformly provided a good or excellent result in patients of all ages who had systemic lupus erythematosus at a mean length of follow-up of sixty-six months. An increased incidence of local wound complications, which were unrelated to the use of corticosteroids, should be expected in patients with systemic lupus erythematosus who undergo prosthetic arthroplasty of the hip.

Abstract
Twenty-nine of the 129 patients with RP seen at the Mayo Clinic between 1943 and 1984 had renal involvement. These patients were older, had arthritis and extrarenal vasculitis more frequently, and had a significantly worse survival rate than those without renal involvement. Renal biopsies were obtained in 11 of these 29 patients. The predominant lesions were mild mesangial expansion and cell proliferation, and segmental necrotizing glomerulonephritis with crescents. Small amounts of electron-dense deposits, predominantly mesangial, were noted on electron microscopy. Immunofluorescence revealed faint deposition of C3 and/or IgG or IgM, predominantly in the mesangium. Autopsies were obtained in 13 of the 47 patients who had died. Information regarding the renal pathology was available in 10 of these 13 autopsies. At the time of the initial evaluation at the Mayo Clinic, 6 of these 10 patients had evidence of renal involvement. At autopsy, none of these 10 patients had evidence of active renal vasculitis or segmental necrotizing glomerulonephritis, but 8 of the 10 patients exhibited variable degrees of vascular and glomerular sclerosis, segmental mesangial proliferation, tubular loss, and interstitial lymphocytic infiltrates. These observations expand the limited information available in the literature, which is based on 11 previously published case reports of renal involvement in RP. In only a few of our patients and previously reported patients were the manifestations of the disease limited to the systems characteristically involved in pure RP. The frequent coexistence of other autoimmune and connective tissue diseases supports the role of immune mechanisms in the pathogenesis of this syndrome. Deposition of immune complexes is likely to play a role in the pathogenesis of the glomerular lesions associated with RP. Administration of corticosteroids alone is sufficient to induce a complete remission in some cases, while in others the addition of a cytotoxic agent is necessary to control the activity of the disease or to spare corticosteroid side effects and maintain a remission. Immunosuppression-related infectious complications and undetected relapses after discontinuation of immunosuppressive therapy are largely responsible for the morbidity and mortality observed in these patients.

Abstract
Gold compounds, often used in the treatment of rheumatoid arthritis, have been associated with gastrointestinal disturbances in some patients. Use of auranofin, an oral gold preparation, in a 50-year-old woman with rheumatoid arthritis resulted in diarrhea, abdominal tenderness, nausea, and vomiting, which persisted despite discontinuation of auranofin therapy. The presumptive diagnosis was gold-induced colitis and eosinophilia. Administration of cromolyn sodium provided relief. Although this complication may be rare, evolving bowel symptoms in patients receiving auranofin demand prompt attention.

Abstract
The ocular and systemic findings in 112 Mayo Clinic patients with relapsing polychondritis were reviewed. The incidence of males and females was equal, with median age at diagnosis of 51 years and the median follow-up of 6 years. Most patients had several organ systems involved at the time of the diagnosis. Twenty-one patients had ocular symptoms at the onset, and 57 developed ocular symptoms during their course. Major ocular complications included proptosis, lid edema, episcleritis/scleritis, corneal infiltrates/thinning, iridocyclitis, retinopathy, and optic neuritis. The major system involvement included otorhinolaryngeal, respiratory, arthritic, renal, cardiovascular, dermatologic, and neurologic diseases. Generally, laboratory studies were not helpful in making the diagnosis but were valuable in monitoring the disease. Based on the experience in these cases, the indications for the various therapeutic modalities are offered.

Abstract
To define the natural history of relapsing polychondritis, the probability of survival and causes of death were determined in 112 patients seen at one institution. By using covariate analysis, early clinical manifestations were identified that predicted mortality. The 5- and 10-year probabilities of survival after diagnosis were 74% and 55%, respectively. The most frequent causes of death were infection, systemic vasculitis, and malignancy. Only 10% of the deaths could be attributed to airway involvement by chondritis. Anemia at diagnosis was a marker for decreased survival in the entire group. There was an interaction between other disease variables and age in determining their impact on outcome. For patients less than 51 years old, saddle-nose deformity and systemic vasculitis were the worst prognostic signs. For older patients, only anemia predicted outcome. The need for corticosteroid therapy did not influence survival.

Abstract
Fourteen patients with systemic lupus erythematosus had splenectomies done between 1960 and 1982 for treatment of severe thrombocytopenia. Thrombocytopenia persisted or recurred within 1 month postoperatively in five patients and within 6 months in three others. Three patients had late recurrence (18, 30, and 54 months after splenectomy); in two it was probably related to withdrawal of immunosuppressive agents or corticosteroids. Median lowest platelet count before splenectomy and median platelet count at relapse or failure of splenectomy were both 8000/microL. Only two patients maintained normal platelet counts without need for corticosteroids or other treatment. These results differ from those in patients with idiopathic thrombocytopenic purpura. Other treatments should be tried before splenectomy is done for thrombocytopenia in patients with systemic lupus erythematosus.

Abstract
The incidence and prevalence rates of connective tissue disease syndromes in Rochester, Minnesota, from 1950 through 1979 are reported. The incidence of definite systemic lupus erythematosus (SLE) has not increased since 1960. The incidence of SLE in the elderly population was higher than that in previous reports. Rates of SLE and discoid lupus erythematosus were approximately equal. Other diagnoses (in decreasing order of frequency) were suspected lupus erythematosus, scleroderma, drug-induced lupus, and overlapping connective tissue disease syndromes. The 10-year survival of patients with definite SLE was decreased, and the survival of patients with suspected SLE was the same as that of the general population.

Abstract
A 20-year community-based study of the epidemiology of juvenile arthritis in Rochester, Minnesota from January 1, 1960 to January 1, 1980 is described. Cases were identified using the 1977 revised American Rheumatism Association criteria for juvenile arthritis. Higher incidence and prevalence rates and a greater predominance of pauciarticular disease were observed than previously reported. Lower rates were observed when a minimum of 3 months' disease duration was used to identify incidence.

Abstract
Clinical and histopathologic features of 15 cases of diffuse fasciitis with eosinophilia are reviewed. The patients experienced an inflammatory scleroderma-like illness without Raynaud's phenomenon or internal organ involvement. Polyarthritis and carpal tunnel syndrome were observed. The clinical courses demonstrated the potential for spontaneous remission, relapse, and late recurrence. Histopathologic features are discussed, as is their relationship to other forms of localized scleroderma. None of the 12 patients treated with corticosteroids has had complete resolution of the skin changes after a median follow-up of 10 months. Unusual associated diseases--acute myelomonocytic leukemia and an evolving myeloproliferative disorder--were observed in two patients.
