Correlation between clinical and ultrasound assessment of the knee in children with mono-articular or pauci-articular juvenile rheumatoid arthritis.

BACKGROUND: Ultrasonography of the knee is a non-invasive, readily available and low-cost tool for demonstrating peri-articular tissues. OBJECTIVE: To correlate clinical features with US findings in the detection, quantification and follow-up of inflammatory signs of the knee in children with pauci-articular juvenile rheumatoid arthritis (JRA). MATERIALS AND METHODS: US of both knees was performed in 49 patients on the same day as the clinical examination. All joints were classified into two groups by clinical criteria: group A (active disease) or group B (quiescent disease). Thirteen patients underwent one or more follow-up examinations. US was performed with a small-parts, 7.5-MHz, electronic linear probe by using a technique previously reported. Quantitative assessment of any effusion and synovial thickening was evaluated at the level of the suprapatellar bursa. Wilcoxon and Spearman tests were employed to compare US findings between the two groups and to correlate clinical and US findings within each group, respectively. RESULTS: US demonstrated significant increase of effusion and synovial thickening in group A joints. US enabled visualisation of clinically undetected popliteal cysts in three patients. Correlation between clinical and US findings was significant in group A and positive, though not significant, in group B. CONCLUSIONS: US seems to be a sensitive and reliable method for the assessment and monitoring of knee joint involvement in pauci-articular JRA.

Body size and colorectal-cancer risk.

Individuals whose energy intake exceeds expenditure are at increased risk of colorectal cancer. To determine whether body-size measurements at different ages were risk factors for cancer of the colon-rectum, we carried out a hospital-based case-control study in 6 Italian areas, 2 of which were in the South. Interviews were conducted with 1,217 subjects of both genders with incident histologically confirmed cancer of the colon, 726 with cancer of the rectum, and 4,136 controls hospitalized for acute, non-neoplastic, non-digestive conditions. The questionnaire included information on sociodemographic factors, and physical activity, a validated dietary history, height, weight at diagnosis and at 12, 30 and 50 years of age and waist-to-hip ratio (WHR). After allowance for education, physical activity, energy intake, family history of colorectal cancer and recent change in weight, the body-mass index (BMI) was significantly associated with colorectal-cancer-risk in men (odds ratio, OR, in highest vs. lowest quintile = 1.7; 95% confidence interval, CI, 1.3-2.3), but not in women (corresponding OR = 0.9; 95% CI, 0.7-1.2). Cases of both gender tended to have higher BMI than controls in adolescence, young adulthood and middle age. Height appeared unrelated to risk. In women, but not in men, WHR was positively associated with risk, independently of BMI (OR for > or = 0.90 vs. < or = 0.81 = 1.6; 95% CI; 1.2-2.1). Thus, excessive weight predicts colorectal-cancer risk in men, whereas abdominal obesity (i.e., a high WHR) represents a more reliable risk indicator in women.

Bone turnover is reduced in children with juvenile rheumatoid arthritis.

Juvenile Rheumatoid Arthritis (JRA) is frequently associated with osteoporosis. In order to determine if JRA osteoporosis is related to reduced formation or to increased bone resorption or both, serum levels of calcium (Ca), phosphorus (PO4), magnesium (Mg), alkaline phosphatase (ALP), parathormone (PTHi), 25-hydroxyvitamin D3 (25-OHD) and 1,25-dihydroxyvitamin D3 (1,25-(OH)2D), osteocalcin (OT), carboxyterminal propeptide (P-coll-1-c), and carboxyterminal telopeptide of type I collagen (ICTP) were evaluated in 47 JRA children, 33 with active disease and 14 in remission. The therapy consisted of nonsteroidal antiinflammatory (NSAIDs) drugs in pauciarticular subset, NSAIDs and Methotrexate (MTX) in polyarticular, NSAIDs and steroids in systemic onset. OT reflects bone formation, P-coll-1-c reflects collagen production and bone formation, ICTP, marker of collagen degradation in bone, indicates bone destruction. Serum levels of Ca, PO4, Mg, ALP, PTHi 25-OHD and 1,25-(OH)2D were comparable in JRA children and in controls. OT (8.7 +/- 3.7 ng/ml vs 9.6 +/- 5.1), P-coll-1-c (301.2 +/- 118.4 ng/ml vs 264.1 +/- 100.1) and ICTP (15.7 +/- 5.7 ng/ml vs 16.1 +/- 6.1) did not differ statistically in the whole group of JRA children vs controls. OT (8.0 +/- 3.5 vs 10.4 +/- 3.8) and ICTP (14.4 +/- 5.4 vs 18.8 +/- 5.4) were significantly lower in active than inactive group. In polyarticular and systemic onset OT and ICTP were significantly lower than in pauciarticular. No difference was found in active patients treated with steroids vs active patients treated with NSAIDS and NSAIDs plus MTX. The lower serum levels of OT and ICTP in active disease support the hypothesis that both bone formation and resorption are reduced in JRA bone turnover.

Effect on lung function of methotrexate and non-steroid anti-inflammatory drugs in children with juvenile rheumatoid arthritis.

We evaluated lung function in a group of patients affected by juvenile rheumatoid arthritis (JRA), without clinical and/or radiological signs of respiratory involvement. We compared the effects on pulmonary function of methotrexate (MTX) therapy combined with non-steroid anti-inflammatory drugs (NSAIDs) to those of NSAIDs alone and correlated lung function to subtype onset, disease duration and disease activity. Our patients were 27 JRA children, subdivided into two groups according to the therapy (group A = 14 patients, treated with a low dose of MTX and NSAIDs; group B = 13 patients, treated with NSAIDs alone). Clinical evaluation, haematological data and pulmonary function tests (PFTs) were obtained in each group at baseline (time 0) and at 1 year (time 1). At time 0 and time 1 PFTs were altered in 51.8% of JRA patients. The restrictive pattern (reduced forced vital capacity, FVC) was the most frequent feature, observed in 22.2% of patients. In group A the mean values of FVC, FEV1 (forced expiratory flow in 1 s), FRC (functional residual capacity), TLC (total lung capacity) and DLCO (diffusing lung capacity of carbon monoxide) were significantly lower compared to those of group B, at time 0 and at time 1. No functional parameter was correlated to subtype, duration or activity of the disease. Our study confirms that abnormalities in PFTs may be detected in JRA patients, even in the absence of clinical and/or radiological signs of lung disease; MTX in combination with NSAIDs does not seem to affect lung function at 1 year more than NSAIDs alone.

Osteoporosis in juvenile systemic lupus erythematosus: a longitudinal study on the effect of steroids on bone mineral density.

Peak bone mass is an important determinant of future bone mass and of the risk of osteoporosis and subsequent fractures. Although some information concerning bone mineral density (BMD) in adults affected with systemic lupus erythematosus (SLE) is available, few data on children and adolescents have been reported. Many variables, such as duration and activity of the disease, reduced sun exposure, and steroid therapy have been suggested as risk factors in the pathogenesis of osteoporosis in SLE. In this study, we longitudinally evaluated, by dual energy X-ray absorptiometry (DEXA), the BMD of 20 young patients affected with juvenile SLE (JSLE), in order to establish the degree of osteoporosis and the influence of steroid treatment, among other clinical variables. At baseline, the mean BMD in JSLE patients was 0.978 g/cm2 and in controls 1.038 g/cm2 (P = 0.31). At 1 year (time 2), this value became 0.947 g/cm2 in JSLE children; the mean individual difference was 0.28 g/cm2 (3.4%). Only in those patients aged 19-25 years BMD was significantly lower than in controls, both at baseline and at time 2. Considering the steroid treatment, no significant difference between the two groups was found either at baseline or at time 2; however, the mean yearly BMD loss in the steroid patients was 0.031 g/cm2 (3.5%) vs. 0.005 g/cm2 (0.5%) in those who had not taken steroids. A significantly inverse correlation between BMD and the cumulative dosage of corticosteroids has been detected. BMD produced a significantly inverse correlation to the cumulative dosage of corticosteroids; no significant correlation has been found between BMD and disease activity or duration.

Multiple myeloma and work in agriculture: results of a case-control study in Forlì, Italy.

OBJECTIVES: To evaluate the relation between the exposure to specific pesticides in agricultural work and the risk of multiple myeloma (MM). METHODS: A case-control study was conducted in the province of Forlì, Italy. Forty-six cases of MM (20 females, 26 males; mean age 64 years, range 40 to 74) identified through the Romagna Cancer Registry in the years 1987-90, and 230 age- and gender-matched controls from the general population were interviewed in-person using a structured questionnaire focused on exposure to pesticides and other occupational and nonoccupational variables. RESULTS: Among nonoccupational factors, the education level and the altitude of the place of residence were related inversely to MM risk. First-degree familiarity for hematolymphopoietic neoplasias and previous herpes zoster diagnosis were associated positively with the disease. A nonsignificant increase in MM risk was observed among workers in agriculture as a whole (odds ratio [OR] = 1.31, 95 percent confidence interval [CI] = 0.62-2.74). An increased risk was associated specifically with the cultivation of apples and pears (OR = 1.75, CI = 1.05-2.91). As regards pesticide exposure, only the chlorinated insecticides were related to an increase in the risk of MM. CONCLUSIONS: This study suggests that agricultural work and exposure to pesticides have a role in the etiology of MM.

Family history of cancer and risk of colorectal cancer in Italy.

Subjects with a family history of colorectal cancer (CRC) are at increased risk of CRC, but quantification of the risk in different populations, the possible differences in risk according to localization of the cancer and the association of family history of other cancers with CRC risk are still open issues. We have therefore analysed data from a multicentric case-control study conducted in six Italian areas between 1992 and 1996 of 1225 incident cases of colon cancer, 728 cases of rectal cancer and 4154 controls admitted for acute conditions to the same network of hospitals as the cases. Unconditional logistic regression models including terms for gender, age, study centre, years of education and number of siblings were used to estimate the odds ratios (ORs) of CRC according to various aspects of history of CRC and other cancers in first-degree relatives. The OR for family history of CRC was 3.2 (95% confidence interval, CI, 2.5-4.1) for colon cancer and 2.2 (95% CI 1.6-3.1) for rectal cancer. Colon cancer was significantly associated with a family history of stomach (OR 1.4), bone (OR 2.1) and kidney (OR 2.3) cancers, while rectal cancer was significantly associated with a family history of lymphomas (OR 2.8). There was a 30% higher risk of colon and rectal cancer in subjects with a family history of any cancer, excluding intestine. The ORs for family history of CRC were 5.2 for colon and 6.3 for rectum when the proband's age was below 45 years. The ORs were similar when the affected relative was a parent or a sibling and in different strata of age of relative(s). For subjects with two or more first-degree relatives with CRC, the risk was 6.9 for the right colon, 5.8 for the transverse and descending colon, 3.8 for the sigma, 3.2 for the rectosigmoid junction and 1.9 for the rectum. This study confirms that a family history of CRC in first-degree relatives increases the risk of both colon and rectal cancer, the association being stronger at younger ages and for right colon.

Risk of cancer other than Kaposi's sarcoma and non-Hodgkin's lymphoma in persons with AIDS in Italy. Cancer and AIDS Registry Linkage Study.

Record linkage was carried out between the national Registry of AIDS and 13 Cancer Registries (CRs) covering, in 1991, about 15% of the Italian population. Observed and expected numbers of cancers and standardized incidence ratios (SIRs) were assessed in 6067 persons with AIDS, for a total of 25,759 person-years. Significantly increased SIRs were found for Hodgkin's disease [8.9, 95% confidence interval (CI) 4.4-16.0], in which seven of 11 cases were of mixed cellularity type; invasive carcinoma of the cervix uteri (15.5; 95% CI 4.0-40.1); and non-melanomatous skin cancer (3.0, 95% CI 1.3-5.9), in which five of eight cases were basal cell carcinoma. An excess was also seen for brain tumours, but this may be partly due to misdiagnosis of brain non-Hodgkin's lymphoma or other brain diseases occurring near the time of the AIDS diagnosis. The risk for all cancer types, after exclusion of Kaposi's sarcoma (KS) and non-Hodgkin's lymphoma (NHL), was approximately twice the general population risk. An increased SIR for Hodgkin's disease in persons with AIDS is thus confirmed, though it is many times smaller than that for NHL. An association with invasive carcinoma of the cervix is also shown at a population level. The excess of non-melanomatous skin cancer seems to be lower than in transplant recipients.

Arthritis as a presenting feature of non-Hodgkin's lymphoma.

Leukaemia can present with joint swelling in the absence of abnormal haematological findings. Arthritis as a presenting sign of lymphoma, however, is extremely rare. Three children with non-Hodgkin's lymphoma who had joint swelling at the onset of their disease are reported. Two cases showed histological features of anaplastic large cell lymphoma (Ki-1/CD30 positive), and one of angioimmunoblastic T cell lymphoma. In all patients the unusual presentation delayed correct diagnosis.

Performance of the preliminary definition of improvement in juvenile chronic arthritis patients treated with methotrexate. Italian Pediatric Rheumatology Study Group.

OBJECTIVE: To investigate the performance of the core set of outcome measures and the preliminary definition of improvement (PDI) in the assessment of response to methotrexate (MTX) treatment in children with juvenile chronic arthritis (JCA). METHODS: Data were obtained from an open label, non-controlled trial designed to investigate the efficacy of MTX in children with JCA. All patients had the core set of variables assessed at baseline and after six months of treatment. Variables in the core set are: (1) physician global assessment of disease activity; (2) parent or patient (if appropriate in age) global assessment of overall well being; (3) functional ability; (4) number of joints with active arthritis; (5) number of joints with limited range of motion; (6) erythrocyte sedimentation rate. The PDI specifies that to be classified as improved, a patient must show at least 30% improvement from baseline in three of any six variables in the core set, with no more than one of the remaining variables worsening by more than 30%. RESULTS: A total of 111 JCA patients were included in the study. According to the PDI, after six months of MTX treatment 73 patients (66%) were classified as improved and 38 (34%) as not improved. Among the core set variables, parent assessment detected the highest percentage of patients improved (72%) and functional assessment the lowest (37%). CONCLUSION: The PDI identifies about two thirds of patients with JCA treated with low dose MTX as improved. This proportion is similar to that expected to improve based upon a previous controlled study of low dose, oral MTX and provides preliminary evidence of the definition's validity.

Pulmonary involvement in juvenile systemic lupus erythematosus: a study on lung function in patients asymptomatic for respiratory disease.

Pleuro-pulmonary involvement has been well recognized in adults affected with systemic lupus erythematosus (SLE), but few studies have been carried out in children. A longitudinal study on a group of 15 children affected with juvenile SLE (JSLE), asymptomatic for lung disease, was performed, and the prevalence and the features of respiratory function alterations, over a period of 12 months, were analysed. Moreover, a possible correlation between any pulmonary function test (PFT) and disease duration, disease activity, visceral involvement and immunological pattern was evaluated. At baseline, a significant functional lung impairment was present in 40% of patients, with a significantly reduced FVC, VA and DLCO in 26% of them; in 60% of patients at 6 months and in 33% of patients at 12 months. At 6 and 12 months, our data did not show any significant modification in PFTs and the restrictive pattern, observed at baseline, remained unchanged. No correlation between altered PFTs and disease duration, activity and/or immunological findings was found. At baseline, the presence of neurological involvement was the only extra-pulmonary feature correlated to reduced FVC.

The cancer registry in the monitoring of cervical screening practice: the neglected value of the Pap smear in patients diagnosed with CIN3 on biopsy.

Patients diagnosed with CIN3 on biopsy without a Pap smear are an inevitable correlate of the extensive utilization of colposcopy as a basic screening test. In a series of 248 CIN3 cases diagnosed on biopsy and notified to the Romagna Cancer Registry between 1986 and 1993, we evaluated the independent association between the Pap smear result and (1) the final histology diagnosis, (2) the first choice treatment, and (3) the appropriateness of hysterectomy. The patients were grouped into the following categories: (1) no smear, ie colposcopy only (n = 40 or 16%), (2) CIN1, CIN2, LGSIL, and minor changes, (3) CIN3 and HGSIL, and (4) carcinoma. In multiple logistic regression analysis, patients without a Pap smear were used as a reference category. Patients with smears reported as CIN1-2/LGSIL or less as well as CIN3/HGSIL had a significantly lower probability of invasive squamous carcinoma (odds ratio = 0.26 for both categories) compared with those not undergoing cytology. The Pap smear result was not a determinant of the first choice treatment. Hysterectomy had a greater probability of being unnecessary if performed in patients with smears reported as showing CIN3/HGSIL (odds ratio = 5.05) or less. In conclusion, this registry-based study demonstrated that the Pap smear had an independent but neglected value in the assessment of cases reported as CIN3 on colposcopy-guided biopsy.

Regional cerebral blood flow in juvenile systemic lupus erythematosus: a prospective SPECT study. Single photon emission computed tomography.

OBJECTIVE: Using single photon emission computed tomography (SPECT) we evaluated the presence and evolution of changes in brain perfusion in juvenile systemic lupus erythematosus (JSLE). METHODS: SPECT was performed in 14 patients with active JSLE divided in 2 groups: the first included 7 patients without central nervous system (CNS) involvement and the second 7 patients with minor neuropsychiatric symptoms (headache, reactive depression, cognitive impairment, mood swing). SPECT findings were compared to seroimmunological and magnetic resonance imaging (MRI) data. After 6 month followup, a second SPECT scan was performed in 12 of 14 patients. RESULTS: At baseline, SPECT showed perfusion defects in 2 patients without neuropsychiatric symptoms and in 5 patients with CNS involvement. In one of the 7 patients with altered SPECT, MRI showed focal hyperintensities. MRI alterations were observed in another patient who had a normal SPECT scan. Cortical atrophy was present in 5 of 14 patients. Correlation between neuropsychiatric manifestations and SPECT findings was not clearly evident because the major part of JSLE patients with CNS involvement and with SPECT alterations had multiple symptoms, but showed focal hypoperfusion on SPECT imaging. No significant association was found between seroimmunological data and SPECT findings. At followup, improvement of perfusion alterations was observed in 6 of 7 patients with altered SPECT and, in 3 of them, findings might be attributed to changes in steroid treatment. CONCLUSION: Perfusion abnormalities in SLE may represent reversible lesions or subclinical CNS involvement. Moreover, SPECT imaging appears to be useful in detecting and monitoring CNS involvement in SLE.

Intake of selected micronutrients and risk of colorectal cancer.

The relationship between various micronutrients and colorectal cancer risk was investigated using data from a case-control study conducted between January 1992 and June 1996 in Italy. Cases were 1,953 incident, histologically confirmed colorectal cancers (1,225 of the colon and 728 of the rectum), admitted to the major teaching and general hospitals in the study areas, and 4,154 controls with no history of cancer, admitted to hospitals in the same catchment areas for acute, non-neoplastic diseases unrelated to the digestive tract and requiring no long-term modifications of the diet. Dietary habits were investigated using a validated food-frequency questionnaire. Odds ratio (ORs) were computed after allowance for age, sex and other potential confounding factors, including physical activity, total energy and fibre intake. For most micronutrients, ORs were below unity with increasing quintile of intake. The most consistent protective effects were for carotene, riboflavin and vitamin C (Multivariate ORs from the continuous model, with unit set as the difference between the upper cut-point of the 4th quintile and that of the 1st one, were 0.65, 0.73 and 0.80, respectively). Inverse relationships were observed also for calcium and vitamin D (ORs of 0.85 and 0.93, respectively). When the combined effect of calcium and vitamin D and selected anti-oxidants was considered, the OR reached 0.46 in subjects reporting high calcium/vitamin D and high anti-oxidant intake compared to those reporting low intake of both groups of micronutrients. Most results were apparently stronger for colon cancer and among females. Our results provide further support for a protective effect of several micronutrients on colorectal cancer risk and some indications for a specific and stronger effect of selected anti-oxidants.

Methotrexate-associated appearance and rapid progression of rheumatoid nodules in systemic-onset juvenile rheumatoid arthritis.

Rheumatoid nodules are a rare extraarticular manifestation of juvenile rheumatoid arthritis (JRA), usually detected in patients with polyarticular-onset disease and positive rheumatoid factor (RF). To date, there has not been a published report of rheumatoid nodules in systemic-onset JRA. Low-dose methotrexate (MTX) is generally considered to be the most useful second-line drug in the treatment of polyarticular JRA. In adult RA, MTX has been shown to be associated with appearance and progression of rheumatoid nodules. This report describes a 3-year-old girl with RF-negative, antinuclear antibody-negative systemic JRA who developed multiple rheumatoid nodules on the scalp and trunk during MTX therapy. The first nodule developed on the scalp 6 months after MTX treatment was initiated. Previous treatment with azathioprine was not associated with nodulosis. This represents an atypical case of MTX-associated accelerated nodulosis in systemic JRA, and raises the problem of treatment plan modification in the presence of this side effect.

Incidence of second primary cancers in three Italian population-based cancer registries.

This is the first population-based study carried out in a southern European region to evaluate the risk of a cohort of cancer patients for developing further cancers. The Tuscany Tumour Registry, the Ragusa Cancer Registry and the Cancer Registry of Romagna, three of the 14 population-based cancer registries active in Italy, were involved in the present study. Overall, 19,252 incident cases of cancer of the female breast, and of the colon, rectum, lung and stomach were followed-up for 48 358.3 person-years. Only second metachronous cancers were considered. Controlateral breast cancers were analysed separately. Multiple primaries (MPs) were defined according to the IACR-IACR rules. The observed (O) numbers of MPs were compared with those expected (E) from age-, sex- and registry-specific incidence rates. Overall, 463 MPs were diagnosed (O/E = 0.87, P < 0.001). The O/E ratios for cancers of the colon (O/E = 0.66), rectum (O/E = 0.72) and all sites combined (O/E = 0.78) in males were significantly lower than expected. The deficit of observed MPs was significant during the first period (2-12 months) and increased over time. Patients over 65 years of age had a significant lower risk of MP, whereas young cancer patients had significantly higher risks for all cancers and for female breast cancer. Male lung cancer patients had a significantly reduced O/E ratio for stomach cancer (O/E = 0.21). Rectal cancer patients had reduced risks of developing stomach cancer and tumours of all sites combined and a 3-fold increased risk of kidney cancers. Colon cancer patients had an overall reduction in risk of MPs, but female colon cancer patients had a significantly increased risk for tumours of the ovary and small intestine; no significant results were found for primary stomach cancers. Female breast cancer patients had a significantly increased risk of rectal cancer (O/E = 1.97), and when synchronous and bilateral breast cancers were considered, significant overall increases in risk were seen for all cancer sites (O/E = 1.6) and for rectal (O/E = 2), and especially for breast cancers (O/E = 3). The cohort analysed had a lower risk of developing further independent tumours than the general population. Several artefacts may have biased these results: the exclusion of synchronous cancers greatly reduced the overall MP risk, and the age-related differences may have been due to reduced medical surveillance and diagnostic aggressiveness. We have confirmed the increased risk for kidney cancers in rectal cancer patients and the association between cancers of the colon and ovary. The significantly increased risk for rectal cancer in female breast cancer patients is probably due to hormonal and dietary factors. For female breast cancer patients, controlateral breast cancer represented the highest risk. The increased risk of cancer of the small intestine in patients with colon cancer may be due to overdiagnosis within increased medical surveillance.

Effect of routine mammography practice on tumour size of a registry-based series of breast cancer cases compared with those observed in a screening cohort.

Routine mammography (MX) practice based on self-referral is considered not to be susceptible to monitoring at the population level. Invasive breast cancer cases notified to the Romagna Cancer Registry between 1989 and 1991 (total 654) were stratified by MX experience and were compared for the proportion of lesions greater than 2 cm in size (T2+) with cases observed in the study group of the Swedish Two Counties Screening Trial (TCST). Any MX more than 6 months prior to diagnosis was considered a previous routine examination. The proportion of cases registered in Romagna within 6-11 months of the most recent MX was quite similar to that shown by the interval cases of the TCST (50% vs 53%). T2+ cases registered in Romagna 12-23 months (27%) and 24-35 months (19%) after previous MX were similar in frequency to those detected at second and later screens in the TCST (22%). For longer intervals, the percentage of large tumours in the Romagna series increased, up to 45% among the cases registered more than 48 months since last MX (p < 0.0001). The whole group of cases with previous MX in Romagna and its counterpart in the TCST (i.e. interval cases + cases detected at second and later screens) had the same size distribution (35% vs 34%). The frequency of large tumours in the total series from Romagna was greater than in the total study group of the TCST (45% vs 36%, p < 0.0001). The difference was entirely accounted for by the cases with no previous MX.
