This retrospective study included the L1 and L2 vertebrae of 143 participants with osteoporotic vertebral fractures and 429 age- and sex-matched no-fractured controls. Spatial distribution was assessed using the superior/middle and inferior/middle ratios, while heterogeneity was indicated by the quartile coefficient of variation (QCV) and interquartile range (IQR). We used QCT to measure the integral vBMD of the vertebra and the regional vBMD in the superior, middle, and inferior subregions. QCV and IQR were computed for both integral vertebrae and three subregions using voxel values from CT images. Differences between fracture and control groups were analyzed after stratification by age and sex. T-tests and Wilcoxon rank-sum tests assessed differences in spatial distribution and heterogeneity between fracture and control groups. Conditional logistic regression was employed to evaluate the associations between spatial distribution and heterogeneity with osteoporotic vertebral fractures. Trabecular vBMD was higher in the middle subregion of the vertebrae than the superior and inferior subregions. The fracture group had lower mean integral vBMD than controls. In terms of the spatial distribution, significant differences in the superior/middle and inferior/middle ratios of the L1 vertebra were observed between the fracture and control groups in the female 40-60 years group. The superior/middle ratio of the L1 vertebra in males was positively correlated with the fracture risk. Regarding heterogeneity, the fracture group had a higher QCV than the control group. QCV was positively correlated with fracture risk, with no significant variation between sexes. The spatial distribution and heterogeneity of trabecular vBMD are crucial for predicting vertebral fracture risk. These indicators are essential for fracture risk assessment and may inform prevention and treatment strategies.</p>","PeriodicalId":9601,"journal":{"name":"Calcified Tissue International","volume":"116 1","pages":"49"},"PeriodicalIF":3.3,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143604014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the repeatability of measures of frequency-dependent attenuation (FDA, 0.3-0.8 MHz) at three calcaneal ROI, Brooke-Wavell (BW), Jaworski (JA), and foot gauge (FG), under four loading conditions (non-weightbearing, semi-weightbearing, bipedal stance, and unipedal stance). FDA in the calcaneus was assessed in 20 healthy participants (mean (± SD) age, 41.7 ± 19.6 years; height, 1.70 ± 0.16 m; and weight, 70.1 ± 23.0 kg) using a custom-built transmission-mode ultrasound system. Reliability was evaluated using the standard error of measurement (SEM) and limits of agreement (LA) and tolerance (95%TL). Differences in mean FDA values between ROI, loading, and measurement occasions were assessed using a repeated measures ANOVA (α = .05). Mean FDA values ranged between 58.0 ± 32.0 and 77.2 ± 27.6 dB/MHz across all conditions. Repeatability of FDA was dependent on the ROI examined and tended to improve with weightbearing. The narrowest limits for 95%TL ranged between ± 15.1 dB/MHz (JA SWB) and ± 62.7 dB/MHz (BW NWB) across sites. The SEM was approximately 10 dB/MHz for both FG and JA during non-weightbearing and was reduced to around 5 dB/MHz with full weightbearing.

This condition is part of the chronic recurrent multifocal osteomyelitis (CRMO)/synovitis, acne, pustulosis, hyperostosis, and osteomyelitis (SAPHO) spectrum. However, because mandibular involvement may present as unifocal disease, it deserves special attention. Unfortunately, the rarity of this disorder, along with a general lack of awareness, has led to numerous unnecessary and ineffective surgical interventions in the past. While some of these lesions may resolve on their own with only symptomatic management with NSAIDs, there is increasing evidence that lesions refractory to NSAIDs can respond well to bisphosphonates (BPNs). The authors conducted a systematic review following PRISMA guidelines to investigate the effectiveness of BPNs for CNO/SAPHO of the mandible and to assess potential adverse reactions, particularly medication-related osteonecrosis of the jaw (MRONJ). In this review, we identified one randomized controlled trial and nine case series describing the use of bisphosphonates in treating mandibular CNO/SAPHO. While heterogeneity among the studies precluded the extraction of statistically relevant information, BPNs are an effective treatment for mandibular CNO with minimal chance of jaw osteonecrosis and disturbance to the growing skeleton.</p>","PeriodicalId":9601,"journal":{"name":"Calcified Tissue International","volume":"116 1","pages":"47"},"PeriodicalIF":3.3,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143584734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Disease manifestations encompass skeletal hypomineralization with rickets and lung hypoplasia, vitamin B6-dependent seizures, craniosynostosis, and premature loss of deciduous teeth. The clinical presentation can comprise failure to thrive with muscular hypotonia, delayed motor development, and gait disturbances later in childhood. In adults, pseudofractures are a characteristic indicator of severely compromised enzyme activity, but non-canonical symptoms like generalized musculoskeletal pain, weakness, and fatigue, frequently accompanied by neuropsychiatric and gastrointestinal issues are increasingly recognized as key findings in patients with HPP. The diagnosis is based on clinical manifestations in combination with persistently low alkaline phosphatase (ALP) activity, elevated levels of ALP substrates, specifically inorganic pyrophosphate (PPi), pyridoxal 5'-phosphate (PLP) or urine phosphoethanolamine (PEA), and genetic confirmation of a causative ALPL variant. Considering the wide range of manifestations, treatment must be multimodal and tailored to individual needs. The multidisciplinary team for comprehensive management of HPP patients should include expertise to ensure disease state metabolic and musculoskeletal treatment, dental care, neurological and neurosurgical surveillance, pain management, physical therapy, and psychological care. Asfotase alfa as first-in-class enzyme replacement therapy (ERT) for HPP has been shown to improve survival, rickets, and functional outcomes in severely affected children, but further research is needed to refine how enzyme replacement can also address emerging manifestations of the disease.
