The aim of this study was to evaluate the relationship between historical height loss (HHL) and prevalent vertebral fractures (VF) in postmenopausal Moroccan women and to estimate its accuracy as a clinical test for detecting VF. Two hundred eighty-eight postmenopausal women were studied. All subjects had bone density measurements and spinal radiographs. Vertebral bodies (T4–L4) were graded using the semi-quantitative method of Genant. HHL was calculated as the difference between a patient’s tallest recalled height and the current measured height. The mean age was 58.4?±?7.8 years. Thirty-one percent of patients were osteoporotic, and 46.5% had VF. Patients with VF had lost more height than those without VF (median, 2.0 cm (0.26–3.3) vs 0.96 cm (0.33–2.4), p?<?0.05). In univariate analysis, HHL was positively correlated to both number and grade of prevalent VF (p?<?0.05). The area under the receiver operating characteristics curve for the ability of HHL to detect VF was 0.60 (95% confidence interval (CI), 0.52, 0.69). Our HHL threshold for detecting VF was >1.5 cm, its sensitivity was 58%, and its specificity was 61%. The positive predictive value was 53%, and the negative predictive value was 65%. With HHL >1.5 cm, positive likelihood ratio was 1.49 with 95% CI, 1.07, 2.06. Our results demonstrate significant positive associations between HHL, VF, number of VF, and grade of VF. However, this relationship is not clinically pertinent. Consequently, HHL cannot be used as a reliable clinical test for detecting VF in postmenopausal Moroccan women.  相似文献

Ankylosing spondylitis (AS) is characterised by a geographic differences in terms of prevalence and clinical expression of the disease. The aim of our study was to describe the actual features of AS in Morocco and we wanted to examine a large population of patients for evidence of phenotypic clustering that could suggest the presence of distinct clinical entities. We investigated 117 patients with a diagnosis of primary AS according to the modified New York criteria. All patients were evaluated according to a standardised data collection form, including demographic variables and disease history with clinical and radiological features. To analyse our data and try to individualise clinical subsets, we applied a two-step cluster analysis using log-likelihood distance measures. Patient’s mean age at onset was 25.51 ± 10.8 year. The mean BASDAI and BASFI score was 33.5 ± 20.3 and 38.9 ± 27.5, respectively. Radiographic damage was present in 99.1% of the subjects and radiographic hip involvement in 47.3%. Only 52.6% of patients had been treated with disease modifying antirheumatic drugs. Cluster analysis detected two distinct populations within the data set. Statistically significant differences were found between the two groups particularly concerning activity of the disease, age at onset and the hygienic conditions. Our study revealed that the Moroccan AS was active and severe and suggested that the age at onset and the precarious hygienic level has the greatest capacity to predict activity and severity of the disease.  相似文献

Background  

Several factors, in addition to low bone mineral density (BMD), have been identified as risks for fractures, including reduced levels of physical activity, poor balance and low physical performance. The aim of this study was to evaluate the relationship between physical performance measures, BMD, falls, and the risk of peripheral fracture in a population sample of Moroccan women.  相似文献

Heterotopic gastrointestinal cysts (HGIC) are rare congenital cysts that arise anywhere along the gastrointestinal tract. HGICs are infrequently reported in the oral cavity; 0.3% of HGICs are reported in the tongue and even more rarely in the submandibular space. Oral HCIGs are more common in children with only 13 reported cases in adults. In the present report, we discuss the differential diagnoses of the submandibular space lesions and describe a rare case of a very large submandibular space HGIC in an adult patient.  相似文献

Available data are limited concerning long-term lung function (LF) evolution after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in lung transplant (LT) recipients. The aim of this study is to determine the effect of first SARS-CoV-2 infection on long-term LF in LT recipients. We analyzed spirometry results of LT recipients followed at our institution (March 2020 to July 2022) at 3, 6, and 12 months after first SARS-CoV-2 infection. Overall, 42 LT patients of our cohort (70%) with COVID-19 were included for long-term LF analysis. Forced expiratory volume in 1 s (FEV1) declined significantly at 3 months (−4.5%, −97 mL, 95% CI [−163; −31], p < .01), but not at 6 and 12 months (−3.9%, −65 mL, 95% CI [−168; +39], p = .21). Results were quite similar for the forced vital capacity. Spirometry values declined significantly at 3 months after COVID-19 in LT recipients, presented a mixed decline at 6 months, and no significant decline at 12 months.
