Spinal curvatures and quality of life in women with vertebral fractures secondary to osteoporosis.

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.

Two new cancer locations accompanied with palmar fasciitis and polyarthritis.

Only 35 cases of cancer with palmar fasciitis and polyarthritis have been published to date. We report two new cases, one with a transitional cell carcinoma of the renal pelvis and the other with an adenocarcinoma of the uterus. Neither of these locations has been reported in association with palmar fasciitis and polyarthritis. Palmar fasciitis with polyarthritis can occur in a wide range of cancers and warrants extensive investigations for a malignant tumor.

[Initial manifestations and late diagnosis in chronic atrophic polychondritis: apropos of a series of 15 patients].

An auricular or nasal chondritis or a saddle nose deformity are the initial manifestation in half of cases of relapsing polychondritis; the other initial manifestations are various and less evocative; polyarthritis, laryngo-tracheal symptoms, episcleritis which delay the diagnosis. From 15 cases of relapsing polychondritis, the diagnosis time from the first symptom are studied; this one is long, about 3 years and 6 months (from 3 months to 17 years) in 13/15 of the cases even if the first manifestation is typical (external chondritis). In two cases only, the diagnosis was established after the first attack. This late of diagnosis had socioeconomical impact and exposed to severe complications like tracheal chondritis.

[HLA DRB1 polymorphism in rhizomelic pseudo-polyarthritis and Horton disease].

Some studies have suggested that distribution of HLA DRB1 alleles in polymyalgia rheumatica (PMR) resembles that found in giant cell arteritis (GCA). However these data are controversial. OBJECTIVE--To evaluate in French native patients whether PMR immunogenetically resembles GCA in determining HLA DRB1 alleles. PATIENTS AND METHODS--Fourty-five patients were included in the study. Twenty-one patients with PMR alone (Bird's criteria) and 24 with GCA (ACR criteria). In 11 patients, GCA was associated with PMR. HLA DRB1 genotype was determined by PCR-RFLP analysis. Statistical analysis was performed by the chi 2 test and determination of the odds ratio (OR). Two hundred and thirty-three unselected normal healthy subjects served as controls. RESULTS--A significant increased prevalence of HLA DR1 was observed in patient with PMR alone and an absence of DR7 (0% vs 10.3%, p = 0.02, OR = 0.1). An increased incidence of DR4 and particularly *0401 allele was only found in patients with GCA (OR = 2.4). No patient with isolated PMR had DR7 genotype compared with 25% in GCA (p < 0.001, OR = 0.03). A comparative study between isolated PMR versus GCA showed a significant increased in DR1 and DR3 alleles in isolated PMR and a significant increased prevalence of DR4 and DRB1 *0701 allele in GCA. CONCLUSION--The present study emphasizes the absence of similarity in HLA DRB1 allele distribution between PMR and GCA. The association of DR7 in patient with GCA seems characteristic in French native patients.

[Osteoporotic vertebral crush fractures with severe neurologic manifestations. Apropos of 6 cases].

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).

[Cardiac complications in adult onset Still disease: from pericarditis to tamponade as manifestations].

Pericarditis is a common manifestation of adult still's diseases (ASD), observed in 20% to 3% cases. Pericardial tamponade is more seldom, less than ten cases have been reported in the literature. We reported two observations of patients with ASD and pericardial tamponade above a series of 18 patients with ASD, in one case revealed the disease. The first patient was a 32-year-old women and had fever, arthritis, high white blood cell count and developed pericardial tamponade. The evolution was favourable with bolus of methylprednisolone. In the second case, cardiac tamponade occurred several years after the onset of the disease. Surgical drainage was first required (800 ml) because of inefficacity of oral prednisone. A dramatic improvement was observed after bolus of methylprednisolone. In conclusion pericardial tamponade is a seldom but sometimes the first manifestation of ASD and may required in first intention bolus of methylprednisolone.

Labial salivary gland biopsy assessment in rheumatoid vasculitis.

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.

Increased capillary permeability in systemic rheumatoid vasculitis: detection by dynamic fluorescence nailfold videomicroscopy.

OBJECTIVE: Several histological studies suggest a vascular involvement in rheumatoid arthritis (RA). We evaluated morphological and functional changes of skin capillaries in patients with RA. METHODS: We studied capillary permeability by nailfold fluorescence videomicroscopy in patients with RA with and without systemic vasculitis to establish the sensitivity, specificity, and the prognostic value of the technique for the diagnosis of systemic rheumatoid vasculitis (SRV). Nine patients with SRV, 22 patients with active RA without signs of vasculitis, and 16 controls were evaluated. RESULTS: No difference in conventional capillaroscopy was observed when we compared patients with SRV and RA. Using fluorescence videomicroscopy after intravenous injection of fluorescein sodium, we observed an increase of transcapillary dye diffusion in 9/9 patients with SRV, in 13/22 patients with RA without vasculitis and in 4/16 control patients. Our results give a sensitivity of 100% in SRV, a specificity of 44%, a positive predictive value of 34% and a negative predictive value of 100%. CONCLUSION: Our present study points out the functional alteration of the capillary wall in patients with RA with or without vasculitis and suggests the usefulness of dynamic fluorescence nailfold capillaroscopy in patients with RA when systemic vasculitis is suspected, not as a diagnostic tool, but because of the high negative predictive value of the technique.

[Rheumatoid polyarthritis in the elderly--rhizomelic pseudopolyarthritis: what differences?].

The authors have conducted a comparative retrospective study between polymyalgia rheumatic (N = 26) and rheumatoid arthritis in the elderly (N = 44), including HLA DRB1 genotype determination by PCR-RFLP analysis. No clinical nor biological differences were significant between the 2 groups of patients. However 70% of RA patients had one ore more susceptibility alleles (shared epitope hypothesis) and 50% in polymyalgia rheumatica.

[Unsatisfactory results of intradiscal injection of triamcinolone hexacetonide in the treatment of sciatica caused by intervertebral disk herniation].

Sciatica caused by intervertebral disc herniation can be treated with intradiscal injection of chymopapain. A search for a cheaper and less allergizing product led to triamcinolone hexacetonide, this procedure being known as "nucleorthesis". The first results at 6 months were encouraging. In 3 centres where triamcinolone hexacetonide was tested with a more than 2 years' follow-up 92 patients could be evaluated. The results obtained were considered satisfactory in 34 patients (36.9 percent), but they were poor in 19 patients (20.6 percent), and 39 patients (42 percent) had to be operated upon within 2 years. Return to surgery took place within the 6 months following nucleorthesis in 18 patients (19.56 percent) and beyond this period in 17 patients (22.8 percent) with degradation of the results. Moreover, calcifications were found in 19 out of 38 patients; they were of varying size, sometimes detected only at computerized tomography, and some of them appeared to produce symptoms. All considered, the failure rates, the number of patients who required surgery and the occurrence of large and sometimes symptomatic calcifications make triamcinolone nucleorthesis unacceptable compared with the recognized percentages of success with papain nucleolysis and surgical operations. For these reasons, we consider that this treatment should be abandoned.

[Weismann-Netter and Stuhl toxopachyosteosis. Apropos of 30 cases].

Toxopachyosteosis, a rare bone disease, was described in 1954 by Weissmann-Netter and Stuhl. This congenital osteopathy, which may be familial, is defined by an anteroposterior curvature (toxon = arc) and thickening (pachus = thick) of the shafts of both leg bones. Other bones may be affected. Short stature and delayed walking are other important special features of the disease. It is most often diagnosed late and by chance because of the minimal functional consequences of the deformities. Sequelae of vitamin D-deficient rickets are the main differential diagnosis. The aim of this study undertaken by the Bone and Calcium/Phosphorus Metabolism Section of the Société Française de Rhumatologie (French Society of Rheumatology) was an overall assessment of the disease. The authors report 30 cases of toxopachyosteosis and evaluate their main characteristics on the basis of data from the literature.

[A case of Weismann-Netter and Stuhl toxopachyosteosis with new bone sites].

A case of Weismann-Netter-Stuhl toxopachyosteosis in a 63-year-old man is reported. Bone deformities had been present since the age of 18 months. Tibio-fibular dysmorphism was severe. Radiological evaluation revealed other lesions encountered more rarely: bilateral femoral incurvature and exostoses, bilateral coxa vara, radio-ulnar incurvature and flattening of the last ribs. Two other previously undescribed lesions were seen in this patient; bradymetacarpism of the last four rays of the left hand and dysmorphic lengthening of the left patella. This case illustrates the widespread nature and unusual extent of bone lesions in the context of toxopachyosteosis.
