Abstract
Quantitative ultrasound (QUS) measurement, a different approach to bone fragility assessment, has already been attempted in women with osteoporosis but rarely in men. In order to test its value and ability to identify osteoporotic men, a case-control prospective study was conducted using the Lunar Achilles, a device that measures attenuation and velocity parameters. Broadband ultrasound attenuation (BUA), speed of sound (SOS) and stiffness index (SI), a composite parameter, were assessed through the heel of 66 osteoporotic patients, and compared with the results in 35 controls. Patients had sustained a low-trauma fracture and/or had a lumbar and/or femoral bone mineral density (BMD) more than 2.5 SD below the young male reference value. As expected, all QUS parameters were statistically lower in patients, as were the dual-energy X-ray absorptiometry (DXA) measurements at the hip and lumbar spine. The two methods were compared for their ability to predict the risk of osteoporotic fractures. The odds ratios (ORs), with their 95% confidence limits, for fractures per 1 SD decrease were significant, especially for SOS and SI (OR = 2.3 [1.4-3.6] and 2.1 [1.3-3.3] respectively) and to a lesser extent for BUA (1.6 [1.0-2.4]). Our study suggests that QUS is associated with a history of low-trauma fracture in men; sensitivity is, however, less than when results are compared with BMD measurements (OR = 2.8 [1.6-5.0] and 3.4 [1.6-7.0] for lumbar spine and hip, respectively). Prospective studies are required before QUS can be recommended for clinical use in male osteoporosis.

Abstract
OBJECTIVES To compare the efficacy and safety of etidronate and alendronate in patients with postmenopausal osteoporosis and to assess the efficacy of either bisphosphonate in combination with hormone replacement therapy (HRT). PATIENTS AND METHODS In this pragmatic study, the main efficacy criterion was the mean annual change in bone mineral density (BMD). Patients who had a past or current history of etidronate or alendronate treatment for postmenopausal osteoporosis with at least 18 months follow-up and an evaluation in 1999 were eligible. Recruitment was in an outpatient clinic with a special focus on metabolic bone diseases. Osteoporosis was defined as at least one low-energy fracture or as a lumbar spine or femoral neck BMD decrease to at least 2.5 SD below the mean in young women. HRT was not an exclusion criterion provided treatment duration was longer than 1 year. Etidronate was given cyclically (14-day courses in a dosage of 400 mg/d separated by 76-day intervals with calcium and vitamin D supplementation) and alendronate was given daily in a dosage of 10 mg/d. RESULTS Of the 99 patients who met our inclusion criteria, 53 received etidronate (including 23 on HRT) and 46 alendronate (18 on HRT). Repeat BMD measurements were obtained in 88 patients, including 11 who stopped their bisphosphonate therapy within the first year of use because of adverse events. Lumbar spine BMD (mean +/- SD) increased significantly both in the etidronate group (+2.1% +/- 0.7%/year) and in the alendronate group (+5.3% +/- 0.9%/year). The increase was significantly greater with alendronate (P< 0.01). The lumbar spine BMD increase was largest in the patients on alendronate and HRT (+6.5% +/- 1.4%/year) and was smallest (and nonsignificant) in the patients on etidronate without HRT (+ 1.2% +/- 0.8%). Femoral neck BMD showed no significant changes in any group. In the intention-to-treat analysis, fractures occurred in 12 etidronate patients (22.6%) and six (13.0%) alendronate patients (nonsignificant). Adverse events requiring bisphosphonate discontinuation before the scheduled date of the follow-up BMD measurement occurred in one patient (1.9%) in the etidronate group (generalized osteomalacia) and in ten patients (21.7%) in the alendronate group (upper or lower gastrointestinal tract symptoms in six and four patients, respectively; P < 0.01). CONCLUSION Both etidronate and alendronate significantly increased lumbar BMD, but the effect was significantly more marked with alendronate. Conversely, adverse effects, most notably gastrointestinal symptoms, were more common with alendronate, so that premature treatment discontinuation because of adverse events were more common in the alendronate group. Both differences should be taken into account when selecting the best drug for a patient with postmenopausal osteoporosis.

Abstract
UNLABELLED The objective of this study was to evaluate the efficacy of treatments for male osteoporosis selected based on the cause of the disease. METHODS Sixty-three men with osteoporosis (T-score at the lumbar spine and/or femoral neck lower than -2.5) with a mean age of 53+/-11 years were studied. Forty-three (68.3%) had a history of fracturing without trauma (vertebral fractures, 37 patients, 57%). Treatments were as follows: idiopathic osteoporosis: calcium and vitamin D supplements (N = 10) or cyclical etidronate for 2 weeks followed by calcium and vitamin D supplements for 76 days (N = 29); moderate idiopathic phosphate diabetes: calcitriol and phosphate (N = 15); idiopathic hypercalciuria: hydrochlorothiazide (N = 6); and hypogonadism: testosterone (N = 3). RESULTS Percentage change in bone mineral density (mean +/- standard error of the mean) after 18 months: calcium and vitamin D (lumbar spine: 0.6+/-2; femoral neck: 2.2+/-2.2); etidronate (lumbar spine: 3.6+/-1.4*; femoral neck: 0.5+/-1); calcitriol (lumbar spine: 7.0+/-3.5*; femoral neck: 0.0+/-1.4); thiazide diuretic (lumbar spine: 1+/-3.2; femoral neck: -2.3+/-3.7); and testosterone (lumbar spine: 6.8+/-6.4; femoral neck: 2.5+/-2.7), where *P < 0.05 versus baseline. Gastrointestinal side effects occurred in three patients (4.8%), including two on calcitriol-phosphate therapy and one on etidronate therapy. Of the six (9.5%) patients who experienced incident fractures, four were on etidronate, one on calcitriol-phosphate, and one on calcium-vitamin D. No patients discontinued their treatment because of side effects. CONCLUSION Etidronate and the combination of calcitriol-phosphate produce a significant increase in lumbar spine bone mass in men with idiopathic osteoporosis or moderate idiopathic phosphate diabetes.

Abstract
OBJECTIVES To assess the occurrence of bone loss in rheumatoid arthritis (RA) and to determine the factors influencing bone loss (particularly the usefulness of bone turnover markers) over an 18-month period. METHODS A total of 51 patients were studied, 6 men and 45 females (of whom 35 were menopausal). Their mean age was 56 +/- 10 years and the mean RA duration was 12 +/- 10 years. Twenty-eight (55%) were receiving corticosteroids (10 mg/day for a mean duration of 6 +/- 5 years). Several clinical and biological parameters reflecting disease activity or severity were recorded both at the 0 and 18-month investigations. Bone turnover was assessed at baseline by measuring the serum levels of 4 biological markers. Three of them reflected bone formation, i.e., procollagen type I C-terminal propepeptide (PICP), procollagen type I N-terminal propeptide (PINP) and osteocalcin (OC). The fourth, procollagen type I-C terminal telopeptide (ICTP), reflected bone resorption. Bone mineral density (BMD) was measured by dual energy X-ray absorptiometry both at the lumbar spine (LS) and femoral neck (FN) at baseline and 18 months later. RESULTS Bone loss occurred both at the LS: 2.1%, [95% CI: 0.8%-3.4%, P < 0.005] and femoral neck: 3.1%, [95% CI: 1.1%-5.1%, P < 0.005]. Bone loss was markedly increased for postmenopausal women at the FN: 5.3% [95% CI: 2.9%-7.6%, P < 0.005]. Bone loss was not statistically significantly different between users and non-users of steroids. Bone loss at the LS was significantly correlated with both osteocalcin (r = 0.51, P < 0.01) and ICTP levels (r = 0.32, P < 0.05). FN bone loss was correlated with the osteocalcin level only (r = 0.34, P < 0.05). Fast losers (bone loss at the LS above the median) had higher OC (P < 0.01) and ESR (P < 0.05) levels at baseline as compared with slow losers (bone loss at the LS below the median). CONCLUSION Bone loss occurs in RA particularly at the FN and seems to be influenced by increased bone turnover and high levels of inflammation.

Abstract
OBJECTIVE Pachydermoperiostosis is manifested by finger clubbing, hypertrophic skin changes, and periosteal bone formation. We describe 5 cases revealed primarily by their rheumatologic manifestations. Also reported are preliminary experiences on the use of intravenous pamidronate as a treatment. METHODS This is a retrospective study including the analysis of clinical manifestations, laboratory results and morphological examinations gathered from patients' medical records. We evaluated efficacy of treatment with 1 mg/kg iv pamidronate in the 3 new cases. RESULTS Before treatment with iv pamidronate, the patients' global assessment was poor (twice) and very poor (once). The physician's global assessment was poor in 3 patients. After treatment with iv pamidronate, 2 patients had significant improvement. Physician and patient global assessments were very good, good, and moderate. No side effects were observed. All biological variables were within normal ranges at 12 month followup visit. CONCLUSION Pachydermoperiostosis must be recognized by the rheumatologist, since it can present symptomatically through articular manifestations. When conventional treatment modalities fail, iv pamidronate might be useful.

Abstract
We report a new case of axial osteomalacia diagnosed in a 51-year-old white Caucasian male, made particular by its association with sacroiliitis, positive HLA-B27 antigen, and also moderate phosphate diabetes responsible for a decreased appendicular bone mass. The diagnosis was suspected when X-ray evaluation showed increased density and coarse trabeculation mainly involving the pelvis and spine. Dual energy X-ray absorptiometry confirmed the elevated bone density at the lumbar spine (T score: +1.92) contrasting with a decreased bone mass at the femoral neck (T score: -2.33). The diagnosis was confirmed by histomorphometry of the iliac crest showing marked thickening of the cortices (2190 microns +/- 0.574, N = 780 +/- 40) and an increased trabecular bone volume (33.24%, N = 14 +/- 3). Osteoid parameters were also markedly increased with an osteoid volume of 2.1% (N = 1.2 +/- 0.5) and a mean osteoid thickness of 28.7 microns (N = 13 +/- 2.5), with a normal bone fluoride content (0.082%, N < 0.10). Bone resorption as assessed on bone biopsy and by the measurement of markers of bone remodeling (serum procollagen type I C-terminal telopeptide and 24 hr urinary cross-laps to creatinine ratio) was increased. This latter finding was not necessarily due to axial osteomalacia and could be the consequence of moderate phosphate diabetes. The patient was treated with calcitriol which was promptly discontinued due to gastrointestinal symptoms and replaced by calcidiol without any significant effect on the low back pain.

Abstract
A case of extraskeletal Ewing's sarcoma presenting as a large gluteal mass is reported. This is a rare tumor with a frequently grim prognosis. Although the definitive diagnosis requires histological examination, magnetic resonance imaging is useful for determining the location of the tumor, evaluating its spread, and eliminating skeletal Ewing's sarcoma by establishing the integrity of the neighboring bone marrow. The tumor is seen on T1-weighted images as low signal with heterogeneous postgadolinium enhancement. Signal intensity on T2-weighted images is variable. In the case reported here, combination chemotherapy with external beam radiation therapy was ineffective, and the patient died 12 months after the diagnosis.

Abstract
OBJECTIVE To assess the efficacy and safety of percutaneous vertebroplasty in osteoporotic vertebral compression fractures responsible for severe and persistent pain. METHODS Sixteen patients were included in this open prospective study. Inclusion criteria were: one or 2 vertebral fractures responsible for severe pain, i.e., higher than 50 mm on a visual analog scale (VAS: 0-100 mm), scores 3, 4 or 5 according to the McGill-Melzack scoring system, and evolving for more than 3 months. Assessment criteria were the changes over time (Days 3, 30, 90, 180) in VAS and McGill-Melzack scoring system. The changes over time in a generic health status instrument score [the Nottingham Health Profile (NHP)] were also assessed. Statistical comparisons were performed using the Wilcoxon T test. RESULTS There were 9 women and 7 men: postmenopausal osteoporosis (n = 7), corticosteroid induced osteoporosis (n = 2), and male osteoporosis (n = 7). Vertebroplasty was performed in 20 vertebrae. A statistically significant decrease of both VAS (-53%, p < 0.0005) and McGill-Melzack scoring system (p < 0.005) was observed at Day 3. The results were also significant at Days 30, 90, and 180 for both scales (p < 0.005 and p < 0.01, respectively). A significant decrease over time for 5/6 dimensions of the NHP score was also noted: pain (p < 0.01), physical mobility (p < 0.05), emotional reactions (p < 0.05), social isolation (p < 0.05), and energy (p < 0.05). We observed no adverse event, and no vertebral fracture has occurred after 6 months of followup. CONCLUSION Percutaneous vertebroplasty is a useful and safe procedure for treating persistent painful osteoporotic fractures. Controlled studies with longterm followup are required.

Abstract
STUDY DESIGN A prospective cross-sectional case-control study. OBJECTIVES To compare spinal curvatures in women with osteoporosis and control subjects with a new instrument, the curviscope. SUMMARY OF BACKGROUND DATA Few instruments are available for measuring spinal curvatures in the sagittal plane. Most of them have poor reproducibility, and they have been poorly investigated in osteoporosis. METHODS Ninety-eight postmenopausal women were evaluated. They were divided into two groups, according to their bone status: women with osteoporosis with at least one vertebral fracture (n = 51) and control subjects (n = 47). Women with osteoporosis were divided into two subgroups, according to the delay since the last vertebral fracture had occurred (i.e., more or less than 3 months). Quality of life was assessed by using a generic instrument, the Nottingham Health Profile, in patients with osteoporosis only. RESULTS Reproducibility of the curviscope was satisfactory. For kyphosis measurements, the coefficients of variation were 2.8% and 2.4% in control subjects and women with osteoporosis, respectively. Kyphosis values were significantly higher in women with osteoporosis than in age-matched control subjects (63 degrees +/- 13 degrees vs. 52 degrees +/- 11 degrees, respectively; P < 0.005). Nottingham Health Profile scores were significantly different (P < 0.05) in women with osteoporosis with a recently diagnosed vertebral fracture, compared with other women with osteoporosis in two aspects, physical mobility and energy. Kyphosis measurements were significantly correlated with age in the whole group (r = 0.26; P < 0.05). In the Nottingham Health Profile, physical mobility was significantly correlated with kyphosis (r = 0.35; P < 0.05). CONCLUSIONS The curviscope is a reliable tool, particularly useful in the assessment of osteoporosis. Moreover, kyphosis angles measured with the curviscope are markedly increased in women with osteoporosis, compared with control subjects. Finally, an increase of kyphosis angles is associated with decreased physical mobility.

Abstract
BACKGROUND The discovery of osteoporosis in a male requires a careful search for a cause. OBJECTIVE To evaluate etiologic factors in male osteoporosis. PATIENTS AND METHODS Males admitted to our department for osteoporosis were included if they had a nontrauma-related vertebral or peripheral fracture and/or a spinal or femoral neck bone mineral density value 2.5 standard deviations or more below the mean in young subjects. The study was retrospective from 1990 to 1995 and prospective from 1996 to 1997. During the prospective part of the study, each subject underwent a standardized battery of laboratory tests including renal tubular function parameters. Causes identified during these two periods were compared. RESULTS Of the 160 patients included in the study, 28.1% had idiopathic osteoporosis, 22.5% had alcoholic osteoporosis, 19.4% had glucocorticoid-induced osteoporosis, 12.5% had osteoporosis due to moderate idiopathic proximal tubule dysfunction, and 8.8% had senile osteoporosis. The proportion of patients with idiopathic osteoporosis was 30% (23/76) during the retrospective part of the study and 26% (21/84) during the prospective part (nonsignificant difference). Moderate idiopathic proximal tubule dysfunction was found in 2.6% (2/76) and 21.4% (18/84) of patients during these two parts of the study, respectively, a difference ascribable to the routine determination of tubule function parameters during the second part of the study. CONCLUSION An exhaustive search for a cause decreases the proportion of male osteoporosis cases that remain idiopathic. In our study, only 28% of cases were classified as idiopathic, a term that probably indicates involvement of multiple interrelated factors.

Abstract
Quantitative ultrasound (US) measurements have been shown to be a new technique assessing bone status. This study aimed to assess a new US instrument, the DBM Sonic 1200(R) (IGEA) which permits the measurement of the speed of sound in the proximal phalanges (SOSp) of the hand. The results obtained were compared with DXA (SOPHOS) and US measurements at the calcaneus (Achilles(R) LUNAR). The in vivo precision expressed by coefficient of variation was 0.91%. Ultrasound measurements of phalanges were significantly correlated with BMD in the entire group of 90 subjects: osteoporotic patients (n = 47) and controls (n = 43) (r = 0.44, femoral neck and 0.45, lumbar spine, P < 0.01). A significant correlation was also found in the control group (r = 0.33, lumbar spine and 0.38, femoral neck, P < 0.05) but not in the osteoporotic group (r = 0.3, lumbar spine and 0.17, femoral neck, P > 0.05). Mean values for 31 postmenopausal, osteoporotic women and age-matched controls showed a significant decrease in US measurements at the phalanges (P < 0.05) and the calcaneus (P < 0.01) as well as bone mineral density (BMD) at the spine and femoral neck (P < 0.01) in the osteoporotic group. A decision threshold for a sensitivity of 80% for osteoporotic fractures resulted in a specificity value of only 37% for SOSp, between 53 to 65% for calcaneus US measurements and 45 to 56% for BMD. The Z score, the odds ratio, the ROC curves, and areas under the curves plotted for the subgroup of 31 fractures and their healthy controls showed poorer values for SOSp than BMD and calcaneus US measurements. In conclusion, US measurements of phalanges seem to be less efficient than calcaneus US and BMD measurements to distinguish osteoporotic from healthy women. Other studies and also prospective studies are required to assess the interest in fracture risk assessment.

Abstract
OBJECTIVE To study the relationship between bone turnover markers and bone mineral density in patients with rheumatoid arthritis. METHODS We studied 54 patients, 24 of whom were receiving low dose steroids, and compared them to 54 age and sex matched controls. RESULTS An 8.2% decrease of femoral neck bone mineral density (BMD) was found in patients not taking steroids compared with controls (confidence interval 1.2-15.3%). Serum markers of bone turnover -- namely, procollagen type I C-terminal propeptide (PICP) and procollagen type I N-terminal propeptide (PINP), which reflect bone formation, and procollagen type I C-terminal telopeptide, which reflects bone resorption -- were significantly increased compared with controls (p < 0.05, p < 0.01, p < 0.01, respectively). Both PINP levels and PICP levels were correlated with the femoral neck BMD as well as osteocalcin levels: R = -0.32 (p < 0.05), R = -0.29 (p < 0.05), and R = -0.42 (p < 0.01), respectively. The best independent predictors of bone mass (stepwise multiple regression analysis) at the femoral neck were steroid use, osteocalcin levels, age, height, the presence of rheumatoid factor, and the Health Assessment Questionnaire score, which explained 61.6% of the variance in femoral neck BMD. CONCLUSION Elderly patients with RA using steroids with severe disease and high levels of osteocalcin have marked osteoporosis at the hip.

Abstract
This multicenter randomized, double-blind, controlled study was performed to compare the efficacy and tolerability of chondroitin sulfate (CS, Condrosulf, IBSA, Lugano, CH) 1200 mg/day oral gel vs CS 3 x 400 mg/day capsules vs placebo, in patients with mono or bilateral knee osteoarthritis (Kellgren and Lawrence radiographic score grade I to III). A total of 127 patients, 40 of whom were treated with CS 1200 mg/day, 43 with CS 3 x 400 mg/day and 44 with placebo, were included in the statistical analysis of this 3-month treatment study. In the CS groups, Lequesne's Index and spontaneous joint pain (VAS) showed a significant reduction of clinical symptoms (P < 0.01 for both parameters), while only a slight reduction was observed in the placebo group (P = ns for Lequesne's Index and P < 0.05 for VAS). The physician's and patient's overall efficacy assessments were significantly in favour of the CS groups (P < 0.01). The treatment carried out with the three formulations was very well tolerated. In conclusion, these results indicate that CS favours the improvement of the subjective symptoms, improving the joint mobility. An additional consideration is that the efficacy of 1200 mg CS as a single daily dose does not differ from that of 3 x 400 mg daily doses of CS for all the clinical parameters taken into consideration.

Abstract
OBJECTIVE To compare the results of pulmonary function tests (PFTs) and high resolution computed tomography (HRCT) of the lungs in rheumatoid arthritis (RA) patients. METHODS Sixty eight patients (54 women, 14 men) fulfilling the revised criteria for RA were consecutively included in a transversal prospective study. Their mean age was 58.8 years (range: 35-82) and the mean duration of the disease was 12 years (range: 5-16). Rheumatoid factor was positive in 52 patients (76.5%). Fifty two patients (76.5%) were lifelong non-smokers. Detailed medical and drug histories were obtained. PFTs comprised spirometry and gas transfer measurements. Results for PFTs were expressed as percentage of predicted values for each individual adjusted for age, sex, and height. HRCT was undertaken with a Siemens Somatom Plus. RESULTS A significant decrease of FEV1/ FVC, FEF25%, FEF50%, FEF75%, FEF25-75%, and TLCO was observed (p < 0.05) and 13.2% of the patients had a small airways involvement defined by a decrease of FEF25-75% below 1.64 SD. The most frequent HRCT findings were: bronchiectasis (30.5%), pulmonary nodules (28%), and air trapping (25%). The patients with small airways involvement had a high frequency of recurrent bronchitis (75% v 34%, p = 0.05) and bronchiectasis (71% v 23%, p = 0.019). The patients with bronchiectasis were characterised by low values of FEV1, FVC, FEF25-75%, and TLCO (p < 0.01), a high prevalence of small airways involvement (29% v 5%, p = 0.019), and a low prevalence of HLA DQA1 *0501 allele (14% v 33%, p < 0.05). CONCLUSION This study suggests a significant association between small airways involvement on PFTs and bronchiectasis on HRCT in unselected RA patients.

Abstract
Two women, 31 and 19 years old, developed acute back pain with non-traumatic vertebral fractures one month after delivery in one case, and during the 9th month of gestation in the second case. For the first patient, the evolution was favorable with an increase of bone mineral density (15.2% over fourteen months under calcium and vitamin D). Ten years later, the osteoporosis of the second patient worsened without any new pregnancy. Our observations suggest the possibility of different pathogenies in pregnancy-associated osteoporosis.

Abstract
OBJECTIVES To study bone mass and the factors that influence bone mass in rheumatoid arthritis patients versus controls. PATIENTS AND METHODS 85 patients (73 women) with a mean age of 57 +/- 11 years and a mean disease duration of 13 +/- 9 years were compared to 85 age- and sex-matched controls. Among the patients, 62 (76%) had positive rheumatoid factor tests and 51 (60%) were receiving steroid therapy, with a mean daily dose of 10 +/- 4 mg and a mean duration of 7 +/- 6 years. The following parameters were determined: morning stiffness duration, painful and swollen joint counts, Lee's and Ritchie's indices, Health Assessment Questionnaire score, erythrocyte sedimentation rate, and C-reactive protein. Bone mineral density was measured at the lumbar spine and femoral neck using dual-energy X-ray absorptiometry (Sophos L-XRA). RESULTS In the nonsteroid-treated patients, bone mineral density was similar to that in controls at the lumbar spine but was decreased by 8% (95% confidence interval [CI], 1.8-14.2%) at the femoral neck (0.76 +/- 0.14 g/cm2 versus 0.83 +/- 0.15 g/cm2; P = 0.03). Decreases of 11.5% (95% CI, 8.1-14.9%) at the lumbar spine and 10.4% (95% CI, 6.4-14.4%) at the femoral neck were found in the steroid-treated patients versus the nonsteroid-treated patients. In the patient group, femoral neck bone mineral density was significantly negatively correlated with age (r = -0.5), the Heath Assessment Questionnaire score (r = -0.27), and the erythrocyte sedimentation rate (r = -0.25), whereas only the first two variables were significantly correlated with lumbar bone mineral density. A multiple linear regression model including age, glucocorticoid use, rheumatoid factor, the Health Assessment Questionnaire score, and the erythrocyte sedimentation rate was constructed and adjusted for the number of variables. This model explained 44.7% of the variance of femoral neck bone mineral density. CONCLUSION Rheumatoid arthritis is associated with a decrease in bone mass that is most marked in patients with active and/or severe disease and in those who take glucocorticoids.

Abstract
We evaluated ultrasound propagation through the calcaneus using the Achilles Lunar unit in patients with postmenopausal or glucocorticoid-induced osteoporosis. Speed of sound, broadband ultrasound attenuation and a combination of these two parameters called stiffness were determined. Reproducibility was 0.23%, 2.6%, and 2.6% for these three parameters, respectively. Bone mineral density measured at the spine and femoral neck by absorptiometry was significantly correlated with all three ultrasound parameters in the women with postmenopausal osteoporosis (n = 47) and in the controls (n = 42). In the patients with glucocorticoid-induced osteoporosis (n = 35), only speed of sound was significantly correlated with the bone mineral density measurements. Mean values in the subjects with postmenopausal osteoporosis and in their age-matched controls were 1473 +/- 27.2 m/sec versus 1500.6 +/- 29.6 m/sec for speed of sound, 95.3 +/- 9.6 dB/Mhz versus 105.7 +/- 10.1 dB/Mhz for broadband ultrasound attenuation, and 56.1 +/- 13.2 versus 70.9 +/- 14.1 for stiffness, indicating a significant difference (P < 0.01). Z scores were -0.91, -1.1, -0.93, -0.97, and -1.05 for bone mineral density at the spine, bone mineral density at the femoral neck, speed of sound, broadband ultrasound attenuation and stiffness, respectively. Receiver Operating Characteristic curves showed that there were no statistically significant differences between the ultrasound parameters at the calcaneus and the absorptiometry measurements at the spine and femoral neck. Mean values in glucocorticoid-treated patients and age-matched controls were 1480 +/- 26.9 m/sec versus 1505.1 +/- 30.3 m/sec for speed of sound, 99.2/-11.4 dB/Mhz versus 105.9 +/- -10.2 dB/Mhz for broadband ultrasound attenuation, and 60.7 +/- 14 versus 72.1/14.5 for stiffness, again indicating a significant difference (P < or = 0.01). Z scores were -0.55, -0.65, -0.8, -0.67, and -0.78 for bone mineral density at the spine, bone mineral density at the femoral neck, speed of sound, broadband ultrasound attenuation and stiffness, respectively. Our data suggest that ultrasound parameters measured at the calcaneus are useful for evaluating postmenopausal and glucocorticoid-induced osteoporosis.

Abstract
UNLABELLED Osteolytic metastases and spinal myeloma lesions are difficult to treat because they denote disseminated malignant disease. The pain-relieving and other effects of radiation therapy are delayed. We evaluated short- and medium-term outcomes of vertebroplasty in this indication, in patients with severe or excruciatingly severe pain (McGill-Melsack score 4 or 5) unresponsive to narcotics. PATIENTS AND METHODS forty vertebras were treated in 37 patients including 29 with bone metastases and eight with multiple myeloma. Mean age was 58 years (range 36-83). The spinal segment involved was the cervical spine in five cases, the thoracic spine in 12 and the lumbar spine in 23. Vertebroplasty was done under fluoroscopy guidance after premedication and local anesthesia. RESULTS thirty-six patients (97.3%) reported a decrease in their pain 48 hours after the procedure; five of these patients (13.5%) were completely free of pain, 20 (55%) were significantly improved and 11 (30%) were moderately improved. One patient failed to respond. The clinical results were not correlated to the extent of vertebral body filling. Beneficial effects were increased or unchanged in 100% of cases after one month, 88.9% after three months and 75% after six months. Leakage of the cement outside the vertebral body occurred in 29 cases (72.5%), usually into the paraspinal soft tissues (n = 21,52.5%). Leakage was usually clinically silent and only two patients developed severe nerve root pain due to leakage into a neural foramen, with in both instances a favorable outcome after surgery. CONCLUSION Vertebro- plasty is simple and effective for the treatment of osteolytic metastases and multiple myeloma lesions, but should be performed only in centers with neurosurgical and/or orthopedic surgery units because of the possibility of severe complications.

Abstract
UNLABELLED Rheumatoid arthritis is associated with osteopenia possibly related to increased bone resorption. Until recently, the markers used to evaluate bone turnover lacked specificity, and as a result studies were difficult to interpret. OBJECTIVES To study bone remodeling in patients with rheumatoid arthritis, with special attention to the effects of corticosteroid therapy. PATIENTS AND METHODS Forty-eight patients (36 women and 12 men) with a mean age of 54.6 +/- 11.6 years and a mean disease duration of 11 +/- 9 years were studied. Thirty-nine patients (81%) had positive tests for rheumatoid factors, and 21 (43.7%) were under corticosteroid therapy, with a mean treatment duration of 4.5 +/- 2.9 years and a mean daily dosage of 9.4 +/- 2.5 mg prednisone. A group of age- and sex-matched controls was also studied. Serum levels of procollagen Type I C-terminal propeptide (PINP), procollagen Type I N-terminal propeptide (PINP), and procollagen type I C-terminal telopeptide (ICTP) were determined in all patients and controls. The first two markers reflect bone formation and the last bone resorption. Other tests performed in each patient were the erythrocyte sedimentation rate, serum C-reactive protein, serum total alkaline phosphatase, serum osteocalcin, 24-hour urinary hydroxyproline excretion, and calcium/creatinine ratio in a morning urine sample. Several clinical parameters were used to evaluate disease activity and severity in the rheumatoid arthritis patients. RESULTS ICTP levels were significantly elevated in the patients as compared with the controls (6.6 +/- 3.9 ng/ml versus 3.1 +/- 1.2 ng/ml, P = 0.0001), whereas no significant differences were found for PICP or PINP. Similar results were found when the analysis was confined to nonsteroid-medicated patients. Conversely, PICP levels were higher in steroid-medicated patients than in controls (P = 0.0132) and were correlated with steroid therapy duration (r = 0.436). ICTP levels were correlated with age (r = 0.3), Lee's index (r = 0.585), the Health Assessment Questionnaire score (r = 0.391), and the erythrocyte sedimentation rate (r = 0.442). Urinary hydroxyproline excretion was elevated in 41.6% of the patients. CONCLUSION Our data suggest that rheumatoid arthritis is associated with increased bone resorption, and that steroid therapy further accelerates bone remodeling in this disease.

Abstract
OBJECTIVE To assess the radiographic features of erosive arthropathy of the hands occurring in patients undergoing hemodialysis, and its relationship with metabolic abnormalities. PATIENTS AND DESIGN A retrospective study of hand radiographs of 80 patients on maintenance hemodialysis was performed with the aim of detecting erosive arthropathy. RESULTS AND CONCLUSIONS Ten patients showed erosive arthropathy of the hands with a predilection for distal interphalangeal joints. The first joint abnormality was joint space narrowing with or without erosion. The mean duration of hemodialysis was 5 years (range 1-15 years). The development of arthropathy could not be related to a metabolic factor. The pathogenesis of arthropathy of the hands is possibly multifactorial, accounting for the disparate descriptions of the radiographic features in the literature.

Abstract
The objective of the study was to assess the efficacy and the safety of pamidronate (APD) in recalcitrant reflex sympathetic dystrophy (RSD). Ten women and 13 men with a mean (+/-standard deviation, SD) age of 44 +/- 11 years were included. The involved sites were: the ankle (n = 10), the foot (n = 7), the hand (n = 3), the hip (n = 2), the knee (n = 2) and the shoulder (n = 1). Some patients had more than one site involved. Mean (+/-SD) duration of the disease was 15 +/- 13 months. RSD was in pseudo-inflammatory phase in 16 patients and in ischaemic phase in 7 patients. RSD was post-traumatic in 17 cases; 11 patients have been previously treated unsuccessfully by sympathetic blockades. APD was administered intravenously (perfusion) to a dose of 1 mg/kg/day during 3, 2 or one day. Fourteen patients received APD during 3 consecutive days whereas 7 patients have been treated during 2 consecutive days and 2 patients only during 1 day mainly due to adverse events. Efficacy was assessed by a decrease of pain = visual analogic scale (VAS, 0-100 mm) and verbal scale (PVS, range 0-3). Moreover, the patient and the observer have estimated the efficacy of the treatment on a verbal scale (EVS, range 0-3). Measurements of these parameters were performed immediately before the treatment and 7, 30, 60 and 90 days later. The maximum duration after treatment was 9 months. A significant decrease of VAS and PVS were observed between D0 and D30 (p = 0.0002 and p = 0.0002 respectively), D0 and D60 (p = 0.0004, p = 0.0004 respectively), and D0 and D90 (p = 0.00003, p = 0.0001 respectively). A significant increase of EVS was only observed between D0 and D90 (p = 0.03). Adverse events were noted in 14 patients: transient fever (n = 6), venous inflammation (n = 2), transient symptomless hypocalcaemia (n = 3), nausea (n = 1), lymphopenia (n = 1), transient hypertension (n = 1). These results suggest an efficacy of APD in recalcitrant RSD. Double-blind placebo controlled studies are required to back up these preliminary results.

Abstract
Articular joint disease frequently occurs in women during menopause. It mainly affects the terminal interphalangeal joints (and is responsible for the formation of small, hard nodules, known as Heberden's nodes) and the metacarpophalangeal joint the thumb (root arthrosis). Clinical diagnosis is not difficult and the disorders are often little troubling and considered only secondary in an overall functional context. However, they can change the quality of life of these patients, making many daily activities difficult to perform. They thus remain a common reason for outpatient visits, although their disfiguring nature is sometimes the main motivation of these patients.

Abstract
Use of methotrexate to treat rheumatoid arthritis is associated with pulmonary adverse effects in 3% to 5% of cases. In addition to immunoallergic lung disease, bronchitis and pneumonia due to pyogenic organisms, opportunistic lower respiratory tract infections have been reported, including, to our knowledge, 18 cases of Pneumocystis carinii pneumonia. We report two new cases of P. carinii pneumonia in methotrexate-treated rheumatoid arthritis patients. One case occurred in a 62-year-old woman with a nine-year history of seropositive rheumatoid arthritis treated for the last seven months with methotrexate, 15 mg per week, and prednisone, 10 mg/d. The other patient was a 58-year-old woman who had been diagnosed with rheumatoid arthritis 18 months earlier and had been receiving 15 mg per week of methotrexate for eight months in combination with 12.5 mg of prednisone per day. Both patients had negative tests for the human immunodeficiency virus. Symptoms consisted of fever, cough and dyspnea, with interstitial infiltrates on chest films, hypoxia, and lymphopenia (700 and 600/mm3, respectively). The diagnosis was confirmed by bronchoalveolar lavage. Both patients recovered under treatment with trimethoprim-sulfamethoxazole. An analysis of the 20 cases of P. carinii pneumonia reported to date in methotrexate-treated rheumatoid arthritis patients demonstrated a number of characteristics: the rheumatoid arthritis was of recent onset in some cases (a few months in one patient); lymphopenia was present in two thirds of cases; one-third of patients were not receiving corticosteroid therapy; the dosage and duration of methotrexate therapy varied widely, from 5 to 30 mg per week and two to 48 months; and four patients died.

Abstract
We present a retrospective study of 82 cases of spinal tuberculosis diagnosed over the last 30 years. An increasing incidence of this disease not related to HIV infection has become apparent since 1992. 24% of patients were born outside continental France. The intradermal reaction was negative in 10% of patients. Discovertebral lesions detected in 93% of patients was the most frequent radiological presentation. Spondylitis with osteolysis or bone sclerosis at single or multiple levels was seen in the others. Tuberculous lesion of the posterior arch was associated in 10% of patients. In most cases CT scan showed a fragmentary vertebral destruction which was characteristic of the disease. MRI revealed the precise extent of the lesions into the spinal canal. Morphologic features suggestive of the tuberculous nature of paravertebral abcesses could be demonstrated when slices were performed in the axial or coronal plan. Tuberculous involvement of the spine is still a frequent disease. The main clinical and radiological findings are presented.

Abstract
OBJECTIVE The incidence of destructive spondyloarthropathies (SpA) in hemodialysis can reach 50% after 10 years of treatment. Few studies have analyzed the magnetic resonance (MR) appearance of destructive SpA and data are controversial. Our objective was to evaluate the computerized tomographic (CT) scan and MR appearance of destructive SpA in comparison to infectious spondylodiscitis. METHODS 23 destructive SpA were observed in 11 patients who had undergone hemodialysis [mean duration of treatment 12 years (89-228 mo)]: 17 SpA of the cervical spine, one of the dorsal, and 5 of the lumbar spine. CT scans at all levels demonstrating narrowing and discovertebral erosions were performed without injection. MRI was performed with T1 and T2* weighted spin echo sequences (0.5T) without gadolinium injection. Radiographs were analyzed by 2 independent examiners. The data concerning MRI of infectious spondylodiscitis were based on a study of 57 personal cases and literature reports. RESULTS CT scan appearance was similar in all cases, especially showing multiple small well defined lucencies of the vertebral endplates. In 9 patients, MRI showed low signal intensity of the disk and the adjacent vertebral endplates on T1 and T2* sequences. In no case was discal or vertebral high signal intensity on T2* sequence noted. No periodontoidal pseudotumor was observed. CONCLUSION CT scans and MRI of destructive SpA, even nonspecific, are different from those observed in infectious spondylodiscitis, particularly due to the absence of discal and vertebral hypersignal on T2* sequences.

Abstract
Although factors that appear to predict long-term outcomes of rheumatoid arthritis have been identified, there is no consensus about the treatment early in the disease. To determine how French office- and hospital-based rheumatologists treat early rheumatoid arthritis, we created three clinical vignettes corresponding to different levels of severity of early rheumatoid arthritis (less than six months' disease duration). Cases 1 and 2 were relatively young patients (35 and 50 years), and Case 1 had numerous poor prognosis factors. Case 3 was 80 years of age. Rheumatologists were asked to indicate which medications they would use at presentation and after one year of a favorable or unfavorable course. The study was conducted by questionnaire (response rate, 58%). Of the 185 rheumatologists who completed the questionnaire, 81% were male and 19% female; mean age was 42 +/- 8 years. In Cases 1 and 2, nonsteroidal antiinflammatory drugs were given by 99% of respondents; second-line drugs were prescribed at presentation by 93% of respondents in Case 1 and 86% in Case 2, and methotrexate was more likely to be used in the presence of poor prognosis factors (23% in case 1 and 7% in Case 2). In the event of an unfavorable course after one year, a larger proportion of rheumatologists prescribed glucocorticoid therapy (65% in Case 1 and 20% in Case 2), and there was a shift from "conventional" to "modern" second-line drugs, with more widespread use of methotrexate (65% in case 1 and 18% in case 2). In the 80-year-old patient, glucocorticoid therapy was used more often than nonsteroidal antiinflammatory drugs and second-line drugs (gold salts, hydroxychloroquine, sulfasalazine) were prescribed by 40% of rheumatologists at presentation and by 67% after one year of an unfavorable course; in the latter situation, methotrexate was selected in 24% of cases. In contrast to conventional recommendations, many French office- or hospital-based rheumatologists use second-line drugs very early and base their choice of medications on the estimated risk of severe disease and on the age of the patient.

Abstract
A retrospective medical record-based study of cases of peripheral pyogenic arthritis diagnosed in a rheumatology department between 1966 and 1993 was conducted. Of the 197 cases, 179 were evaluable. Pyogenic arthritis accounted for 0.68% of admissions and 30.3% of bone and joint infections during the study period. Incidence rose gradually from 2.2 new cases per year between 1966 and 1970 up to 6 to 10 new cases per year since 1991. In 88% of cases a single joint was involved, with the most commonly affected sites being the knee (32.5%), hip (22.2%), shoulder (12%) and sacroiliac joint (11.4%). Of the 22 patients with polyarticular arthritis, 19 had involvement of two joints. A portal of entry was identified in 53% of cases. Of the 13% of iatrogenic cases, half occurred after a local corticosteroid injection. The pathogen was identified in 65% of cases. Staphylococcus aureus was the most common organism (56%) followed by streptococci (9.5%) and E. coli (7%). Only three patients had gonococcal arthritis. Mean duration of therapy was four months. Although complications were exceedingly rare, three patients died and three others developed septic shock. Our data suggest that the presentation of pyogenic arthritis has remained essentially unchanged. In particular, we found no increase in iatrogenic forms, in contrast to recent experience with vertebral osteomyelitis.

Abstract
Bone mineral density accounts for 70% to 80% of the mechanical resistance of bone but is unrelated to bone tissue structure. The vertebral fracture risk increases with advancing age irrespective of whether or not bone mineral density decreases, suggesting that changes in bone microarchitecture contribute significantly to the development of osteoporosis. In contrast to bone mass, bone architecture is difficult to evaluate. Among the various methods developed to investigate bone structure, biomechanical studies are of limited value since they are done on cadaver bones. Measurement of microarchitectural parameters (e.g., mean trabecular thickness, density and separation) in bone specimens obtained by needle biopsy is the gold-standard technique. Parameters reflecting trabecular interconnections (e.g., total number of nodes and free ends) can also be measured on needle biopsy specimens. New techniques of as yet unproven validity include star volume and trabecular bone pattern factor measurement. Noninvasive techniques capable of supplying qualitative information about bone tissue are also under study. Ultrasonography can theoretically provide data on bone microarchitecture but has not yet been proven useful in clinical practice. Statistical, structural, or fractal analysis techniques can be used to evaluate bone texture on digitized roentgenograms, computed tomography sections, or magnetic resonance imaging displays; although this approach holds great promise, it is still under evaluation and has not yet been compared with histomorphometry. Lastly, the apparent relaxation time of bone marrow determined using magnetic resonance imaging may also provide information on bone structure.

Abstract
Osteoporotic vertebral crush fractures with neurologic complications are rarely reported in the literature. We report six new cases particularly severe in which death occurred in two cases. The study group included four women and two men with a mean age of 75 years (range: 72-79). Vertebral collapse causing neurological deficit was T5, T9, T11 in two cases, L1 and L3. The mean number of vertebral collapses was three per patient (range: 1-9). Back pain appeared without traumatism 6 weeks before admission (range: 1-24). Neurological complications appeared 2.5 weeks after back pain (range: 1-8). One patient suffered from a paraplegia, three from a paraparesia with bladder dysfunction (n = 1). In one case there was a severe weakness of the levator muscles of the foot and in another a L3 femoral neuralgia with severe bowel and bladder dysfunction. X-rays demonstrated backwards displacement of the posterior cortex in three cases, an intravertebral vacuum phenomenon in two cases and a heterogeneous appearance suggesting a malignancy in two cases. Computed tomography, performed in four patients and tomography in one patient, demonstrated fragmentation of the vertebral body in all the cases and vacuum phenomenon in four cases. Magnetic resonance imaging performed in four cases has confirmed the absence of epiduritis and a compression due to bony structures in two cases. A vertebral biopsy was performed in three cases. Osteoporosis was observed in all the cases and in two cases there was also an osteonecrosis. Surgical treatment was performed in three cases and conservative medical treatment in the other cases. After surgical treatment we have observed an absence of improvement of neurological complications in one case, an improvement in another and finally a full recovery in the last case. After conservative treatment we have noted in two cases an absence of improvement of neurological complications and in one case an improvement of neurological deficit. Two patients died (one after medical treatment and another after surgical treatment).

Abstract
OBJECTIVE To assess the usefulness of high resolution computed tomography (HRCT) of the lungs in patients with rheumatoid arthritis (RA) with and without respiratory symptoms. PATIENTS AND METHODS Eighty eight RA patients with a mean duration of disease 12 (SD 8) years were evaluated. Eleven patients were excluded because of previous exposure to silica. The 77 remaining patients formed two groups according to the absence (group I, n = 38) or the presence (group II, n = 39) of chronic respiratory symptoms. A control group consisted of 51 non-smoking, healthy patients. RESULTS The most frequent abnormalities observed in the 77 RA patients were bronchiectasis or bronchiolectasis (n = 23, 30%), pulmonary nodules (n = 17, 22%), subpleural micronodules or pseudoplaques (n = 13, 17%), ground glass opacities (n = 11, 14%), and honeycombing (n = 8, 10%). Bronchiectasis or bronchiolectasis (p = 0.012), rounded opacities (p = 0.016), ground glass attenuation (p = 0.004), and honeycombing (p = 0.002) were found more often in RA group II (with respiratory symptoms) than in group I (no respiratory symptoms). Non-linear septal opacities were more frequent in group I than in the control group, but other HRCT findings did not differ statistically significantly between group I and the control group. CONCLUSION Bronchiectasis may be a characteristic lung change in RA patients. Abnormalities on HRCT are less frequently observed in the absence of respiratory symptoms than in the presence of such symptoms (29% versus 69%).

Bone tissue in rheumatoid arthritis (2). Pathophysiologic data, pathologic findings, and therapeutic implications. REVUE DU RHUMATISME (ENGLISH ED.) 1995; 62:205-11.

Abstract
The occurrence of bone decalcification during rheumatoid arthritis is well documented, despite discrepancies among published data. The most recent studies support a decrease in bone mass, especially at the proximal femur, although estimations of the extent of bone loss ascribable to rheumatoid arthritis vary. The fracture risk is increased by approximately 100% in rheumatoid arthritis patients. Bone mass is negatively correlated with functional impairment, joint motion restriction and disease activity as assessed by laboratory tests for inflammation. Increased physical activity can reduce bone loss. Markers for bone formation (osteocalcin, procollagen type I carboxy-terminal propeptide) are normal or decreased, whereas markers for bone resorption (hydroxyproline, pyridinoline, and deoxypyridinoline) are elevated. This decoupling of bone formation and resorption may be responsible for bone loss. Although estrogen therapy can keep in check menopause-related bone loss, earlier findings suggesting that estrogens may have beneficial effects on the joint disease itself have been disproven. The value of preventive bisphosphonate therapy is currently under debate.

Bone tissue in rheumatoid arthritis (1). Bone mineral density and fracture risk. REVUE DU RHUMATISME (ENGLISH ED.) 1995; 62:197-204.

Abstract
Rheumatoid arthritis is associated with locoregional decalcification, which can be clearly demonstrated at the distal radius using single-photon absorptiometry. Bone loss at this site is probably due to the predominant involvement of the hands and wrists during rheumatoid arthritis. Estimates of the frequency of generalized bone loss have varied with the measurement technique used and the study design. Studies using dual-photon absorptiometry with a radioactive source have yielded conflicting data. The most recent studies of bone mineral density used dual energy X-ray absorptiometry, which is currently the best method in terms of reproducibility and precision; results suggested bone loss in the proximal femur, whereas lumbar spine measurements were usually normal or very slightly decreased. Findings from the few longitudinal studies are discordant; this may be ascribable to differences in bone mass measurement techniques, study population characteristics, and follow-up duration. Whereas bone loss was not demonstrated in the earliest longitudinal studies, recent investigations suggested that bone mineral density was decreased in rheumatoid arthritis patients as compared with controls. Corticosteroid therapy, even in daily dosages of less than 10 mg/d prednisone-equivalent, was associated with an approximately 10% decrease in bone mass after six months, in both cross-sectional and longitudinal studies. Rheumatoid arthritis patients had a two-fold increase in fracture risk, independently from their bone mass. Factors associated with higher fracture risks were corticosteroid therapy, physical inactivity, and female gender.

Intraosseous lipoma: role and limitations of modern imaging techniques. REVUE DU RHUMATISME (ENGLISH ED.) 1995; 62:147-50.

Abstract
We report a case of intraosseous lipoma involving the ilium in a 37-year-old male. There were no clinical symptoms. Plain films suggested the diagnosis, which was confirmed by computed tomography and magnetic resonance imaging with fat-cancelling sequences. However, we were unable to rule out fatty involution of an old aneurysmal bone cyst. Modern imaging techniques are very reliable for the diagnosis of intraosseous lipoma. Computed tomography is usually sufficient to establish the diagnosis and to guide therapeutic decisions.

Abstract
Clinical and radiographic findings were retrospectively reviewed in a multicentric survey of 58 patients with histologically proven pigmented villonodular synovitis (PVNS) of the hip. The most common clinical features were mechanical pain (47 cases) and limitation of joint motion (47 cases). On plain films, a classic form with large and multiple lucencies was found in 36 cases, followed by an osteoarthritis-like form (9 cases), an arthritis-like form (8 cases), normal radiographic appearance (3 cases), osteonecrosis of the femoral head (one case) and joint destruction with acetabular protrusion (one case). Bilateral involvement of the hips was probable in two patients. In contrast to the knee, the hip showed a high prevalence of bony lesions and joint space narrowing. Although an uncommon disease, PVNS of the hip has to be considered when arthritis is associated with uncharacteristic clinical or radiographic findings.

Abstract
PURPOSE To evaluate lung changes in rheumatoid arthritis (RA). MATERIALS AND METHODS The authors reviewed the computed tomographic (CT) scans from 84 patients with RA with a mean articular disease duration (+/- standard deviation) of 12 years +/- 8 (range, 0.3-45 years). Fifteen patients underwent sequential CT evaluation during 5-65-month follow-up (mean, 18 months). RESULTS Thirty-eight patients (49%) had abnormal CT scans showing the following abnormalities: (a) bronchiectasis and/or bronchiolectasis (n = 23, 30%), (b) pulmonary nodules (n = 17, 22%), (c) subpleural micronodules and/or pseudoplaques (n = 13, 17%), (d) nonseptal linear attenuation (n = 14, 18%), (e) areas of ground-glass attenuation (n = 11, 14%), and (f) honeycombing (n = 8, 10%). Abnormal CT examinations were recorded in 11 of 38 asymptomatic patients (29%) and 27 of 39 symptomatic patients (69%). The following CT abnormalities were found with a significantly higher frequency among patients with respiratory symptoms: (a) bronchiectasis and/or bronchiolectasis, (b) rounded areas of attenuation, (c) areas of ground-glass attenuation, and (d) honeycombing. CONCLUSION CT may be a useful noninvasive tool for recognition of RA-associated lung disease with special emphasis on bronchial and bronchiolar changes.

Abstract
OBJECTIVES To assess the vascular involvement in labial salivary gland (LSG) from patients with rheumatoid vasculitis (RV). METHODS Forty seven patients with rheumatoid arthritis (RA) took part in a prospective study. Among them, 12 had proven RV. LSG biopsy was performed after local anaesthesia. RESULTS Histological appearance of inflammatory vascular damage was observed in all but one patient with proven RV (92%). Inflammatory vascular involvement was also identified in LSG biopsy of seven patients with RA (20%) and only one patient in the control group (8%). A second specimen of LSG was studied after a mean treatment period of six months and failed to show any feature of inflammatory vascular involvement in three of the five cases that were analysed. CONCLUSIONS The study emphasises the high incidence of immunopathological features of microvascular damage in patients with RV. LSG biopsy is minimally invasive and may be a potential useful tool for the diagnosis of RV especially when skin lesions are absent or impossible to biopsy. The assessment of the predictive value of positive LSG biopsy in RA requires a long term prospective study.

Abstract
A 25-year-old man developed multiple eosinophilic granuloma of bone including vertebral and sacral localization. Radiotherapy was initially administered. One year later, a relapse occurred in another vertebrae which was previously irradiated. Percutaneous vertebroplasty was, for the first time to our knowledge performed, in this indication, with a good clinical result with follow-up now for one year. We emphasize that such treatment is permissible only in symptomatic, progressive lesions, with threatened decompensation of spinal stability. This technique should be used only on an adult.
