Our aim was to compare the analgesic efficacy of pamidronate (PAM) and synthetic human calcitonin (CT) in intravenous infusion for recent painful benign vertebral compression in a randomised prospective double-blind study. Twenty-seven patients aged 49-85 years with painful benign non-traumatic vertebral compression were included in the study. They received either PAM (1 mg/kg) or synthetic human CT (1.5 mg) as an intravenous infusion. Pain and functional disability were evaluated before infusion, and 4 and 30 days afterwards. The pain score assessed on a visual analogue scale at day 0 was 5.94+/-2.47 in patients treated with PAM and 6.27+/-2.50 in patients treated with CT (p=0.74); at day 4, 4.8+/-2.80 with PAM vs 3.9+/-2.68 with CT (p=0.37); and at day 30, 3.6+/-3.13 with PAM vs 3.10+/-2.76 with CT (p=0.70). Spinal function scores were 18.21+/-3.17 at day 0 in patients treated with PAM vs 17.23+/-4.42 in patients treated with CT (p=0.69) and at day 30, 13.7+/-5.36 with PAM vs 12.33+/-3.22 with CT (p=0.68). We found no advantage of PAM over CT in a single intravenous infusion for the treatment of painful recent benign vertebral compression. Since CT is ten times less costly, its use should be preferred.

We report five cases of seronegative inflammatory rheumatism associated with nasal polyposis. The patients were four women and one man, mean age 49.5 years (range 42-59 yrs.). Two patients had polyarthralgia predominating in the hands, wrists and knees and two patients had symmetrical acromelic polyarthritis. The fifth patient, a woman, had oligoarticular arthritis. In a single female patient, X-rays showed moderate erosions of both tarsometatarsal bones. The inflammatory syndrome was moderate with mean ESR 23 (12-38) and immunological investigations were negative except for the presence of pANCA (50-200 U) in three patients. HLA-A1, B8, and Bw35 antigens were found in three of the five patients. In all cases, nasal and sinus polyposis (NSP) preceded rheumatism and the joint symptoms were accompanied by worsening of the ENT symptoms. NSP was confirmed by CT scan of the nasal fossae and sinuses. Polyps were surgically removed in four patients and the histology showed neither granuloma nor vasculitis. In four patients the joint symptoms, which responded poorly to nonsteroidal anti-inflammatory drugs (NSAIDs), improved markedly after ENT treatment (surgery and topical steroids) and synthetic antimalarials. The concomitant course of the joint and ENT symptoms suggests there may be a link between inflammatory rheumatism and NSP.

In a previous study, the authors demonstrated that in 17 men with ischaemic atherosclerotic disease the bone mineral density (BMD) of the femoral neck was lower than in matched control subjects. The patients with arterial disease were thinner and were heavier smokers than the controls. Osteoporosis and arterial disease of the lower limbs were perhaps due to common risk factors: tobacco consumption and a low body build index. In order to demonstrate the direct effect of atherosclerosis on bone mineral content (BMC), the authors studied by dual-energy X-ray absorptiometry the BMC of both legs in 18 men presenting symptomatic arterial disease of the lower limbs quantified by measurement of distal systolic indexes by doppler ultrasonography. The mean BMC of the leg more severely affected by arterial disease was significantly lower than the mean BMC of the leg less affected by arterial disease (512 +/- 76 g versus 495 +/- 80 g: p = 0.003). In 13 of the 18 patients, the BMC was lower in the leg more severely affected by arterial disease; in 4 of 18 the difference between the BMC of the left and right legs was less than 1%, and in a single patient the BMC was higher in the leg more affected by arterial disease. Arterial disease of the lower limbs could lead to bone mineral loss.

In our knowledge, we are the first to report an observation on multiple osteomeningioma.

Survival of patients with multiple myeloma (MM) showed no improvement between the 1960s and 1990s. During the last decade, new therapeutic approaches seemed likely to offer hope of prolonging survival. The aim of this study was to examine if this survival increased with the usage of new treatments. The method involves a retrospective study of 123 patients with MM, diagnosed between 1975 and 1999, all receiving treatment. They were divided into two groups: group 1 included 55 patients given the so-called “old treatments” [melphalan-prednisone, cyclophosphamide-prednisone, polychemotherapy (vincristine, melphalan, cyclophosphamide, prednisone (VMCP), VMCP-VBAP)], and group 2 included 68 patients receiving at least one of the so-called “new treatments” (dexamethasone, thalidomide, high-dose chemotherapy followed by autotransplants, bisphosphonates, interferon). The two groups were similar in terms of age, sex ratio and renal impairment, and the percentage of light-chain MM was identical in both groups. Patients who had been given a “new” treatment (group 2) had longer median survival than the patients in group 1 (54 vs 42 months). Independent analysis of each treatment modality showed increased median survival in MM patients treated using autotransplantation compared with untreated patients (125 vs 45 months). Survival was also longer in MM patients treated with thalidomide than in untreated patients (72 vs 42 months). On the other hand, neither bisphosphonates, interferon-alpha nor dexamethasone result in improved survival. Our findings emphasize the increased survival of the MM patients treated with new therapeutic approaches.

It has been suggested that in some patients non-traumatic aseptic osteonecrosis of the hip (AOH) could be the result of the intra-osseous thrombosis. Antiphospholipid antibodies (APL) have been associated with venous and arterial occlusive events and the association between AOH and APL syndrome has been reported.To compare bone vessels of the femoral head in patients operated on for AOH with or without APL.Twenty patients (mean age 47 yrs) with AOH were included: in eight patients APL (IgG-ELISA) were negative (8 GPL units), in nine patients APL were doubtful (8-15 GPL units), and in three patients APL were positive (15 GPL units).Bone vessels were examined: arteriosclerotic lesions, i.e. fibrosis or thickening of the media and rupture of the internal elastic lamina, thrombosis or vasculitis were sought in the femoral heads after total hip replacement or core decompression.Bone vessel lesions were the same in the three groups.

The authors studied by light microscopy the vessels of the femoral head and neck in 38 well preserved specimens from core biopsy. There were 17 cases of osteonecrosis (ON), 11 cases of osteoarthrosis (OA) and 10 cases of reflex sympathetic dystrophy, so called algodystrophy (AD). Mean age of the patients was respectively 44, 45 and 42 years. The sex ratio, M/F, was respectively 12/5, 6/5 and 9/1. Types of staining used were hematoxylin-eosin, Masson Trichrome, P.A.S. and Verhoeff. In counting, thick-walled and thin-walled vessels were distinguished. There was a significant reduction in the number of the thick- and thin-walled vessels, in the ON group, by comparison with the OA and AD groups. An increased number of thin-walled vessels in the AD group were also observed. Morphological study showed an abnormal frequency of fibrosis of the media in the arteries of the ON group, i.e. arteriosclerosis. These data were compared with the few other histopathological studies previously published. The authors recommend further studies in order to precise their frequency and their significance.

Six patients, with vertebral osteoporosis and reflex sympathetic algodystrophy syndrome of the lower limbs, due to moderate diabetes, are presented. Osteoporosis was documented by low CT scan bone density and moderate decrease of bone trabecular volume. Histomorphometric studies found a mild increase of resorption areas. All patients had unremarkable serum phosphorus level (mean: 0.91 +/- 0.13) but increase of urinary phosphorus excretion was documented by phosphate clearance higher than 20ml/mm, phosphate tubular reabsorption lower than 80% and TmPo4/GFR lower than 0.8mmol/l. Phosphate clearance and phosphate tubular reabsorption are studied in two control groups. Mild phosphate diabetes, of unknown incidence and prevalence (need for prospective studies) may be the vector of osteoporosis, vertebral and peripheral. The diagnosis of PD requires determination of phosphate clearance, phosphate tubular reabsorption, TmPo4/GFR and these tests may be useful in the diagnostic work up of bone demineralization disorders. We thought that osteoporosis could be the result of progressive dissolution of bone apatite crystals necessary to maintain normal or sub-normal blood phosphate level in spite of the phosphate diabetes.

The authors report a study of 47 patients admitted for cervical myelopathy (N = 17) or symptomatic lumbar spinal stenosis (N = 30). Nine patients had clinical evidence of coexisting cervical myelopathy and lumbar spinal stenosis. Ten out of the 17 patients having cervical myelopathy had lumbar spinal stenosis as evidenced by sagittal tomography and/or computerized tomography. Nine out of the 30 patients admitted for symptomatic lumbar spinal stenosis had coexisting cervical canal stenosis as evidenced by sagittal tomography. Thirteen out of these 19 patients with both cervical and lumbar canal stenosis had also ankylosing spinal hyperostosis.

One case of CRST syndrome with breast granuloma is presented. The presumed diagnosis were infectious or neoplastic diseases. High doses of corticosteroids led to improvement in breast nodules.
