Secondary causes of osteoporosis in fracture patients

Sex differences in alcohol inhibits bone formation and promotes bone resorption in young male and female rats by altering intestinal flora, metabolites, and bone microenvironment

BACKGROUND

Long-term alcohol intake has toxic effects on osteoblasts and osteoclasts, resulting in decreased bone density, which directly disrupts the composition of the gut microbiota and affects bone metabolism and immune activity. The effects of alcohol on the bones may be closely related to sex. This study investigated the effects of long-term alcohol consumption on bone status in different sexes by examining the gut microbiota, bone metabolism, and immune activity.

METHODS

Young male and female rats were administered a Bio-Serv liquid diet containing 5% alcohol. The effects of alcohol metabolism capacity, bone morphology, bone formation, bone resorption, bone marrow immune activity, gut microbiota, and metabolite differences were analyzed in male and female rats using hematoxylin and eosin staining, micro-computed tomography, enzyme-linked immunosorbent assay, western blotting, 16S rRNA sequencing, and untargeted metabolomics.

RESULTS

Chronic alcohol consumption resulted in excessive osteoclast activation and decreased bone mineral density. Furthermore, alcohol reduced bone metabolism and formation while increasing bone resorption. Bone loss was significantly more severe in female rats than in male rats, indicating that the effects of alcohol on rat bones are related to sex. Chronic alcohol consumption also led to polarization of bone marrow immunoreactivity toward the M1 phenotype. In addition, chronic alcohol consumption affected the composition of gut microbiota, reduced the richness and diversity of intestinal microbiota, and decreased the ratio of Firmicutes/Bacteroidetes. Long-term alcohol consumption also affected fecal metabolites, and 754 differentially expressed metabolites were identified.

CONCLUSIONS

Chronic alcohol consumption increased bone resorption, inhibited bone formation, and affected bone marrow immunoreactivity in young male and female rats. Alcohol can also affect gut microbiota composition and fecal metabolism. Female rats were more susceptible to alcohol, possibly because young female rats have a lower alcohol metabolism, immunomodulatory capacity, and gut microbiota diversity than young male rats.

Insufficiency Fractures vs. Low-Energy Pelvic Ring Fractures - Epidemiological, Diagnostic and Therapeutic Characteristics of Fragility Fractures of the Pelvic Ring

BACKGROUND

Fragility fractures of the pelvis (FFP) encompass two fracture entities: fracture after low-energy trauma and insufficiency fracture without trauma. It is unclear whether the two subgroups differ in terms of diagnosis and therapy. The aim of this retrospective study was to evaluate insufficiency fractures with regard to defined parameters and to compare specific parameters with the fractures after low-energy trauma.

PATIENTS AND METHODS

In the period from 2008 to 2017, 203 patients with FFP were recorded at our clinic (Level 1 Trauma Centre DGU, SAV approval). Of these, 25 had an insufficiency fracture and 178 had a pelvic ring fracture after low-energy trauma. Epidemiological, diagnostic and therapeutic parameters were examined.

RESULTS

There was a relative increase in the insufficiency fracture within the FFP (2008 - 2009: 5.0% vs. 2015 - 2017: 17.8%). In these patients, osteoporosis tended to be more pronounced than in patients after low-energy trauma (t-value: - 3.66 vs. - 3.13). The diagnosis of insufficiency fractures showed increased use of MRI and DECT (60.9% vs. 26.0%) and a high proportion of type IV fractures after FFP (40.0% vs. 7.9%). In terms of therapy, surgical treatment of the insufficiency fracture was sought more often (68,2% vs. 52,1%), with a tendency towards increased use of combined osteosynthesis procedures (14.3% vs. 7.6%).

CONCLUSION

We were able to show that as the number of cases increases, the insufficiency fracture becomes more important within FFP. If these patients tend to have more pronounced osteoporosis, particular attention should be paid to the diagnosis and adequate therapy of the osteoporosis, especially in the case of an insufficiency fracture. In addition to the increased diagnostic testing using MRI and DECT to detect oedema and the increased surgical therapy for this type of fracture, it is also noteworthy that the insufficiency fracture can cause higher-grade fractures after FFP.

Implementing an Electronic Medical Record Osteoporosis Self-Assessment Tool Score Which Identifies Patients at Risk for Osteoporosis Promotes Osteoporosis Evaluation

Introduction:

Osteoporosis affects nearly half of the U.S. population. Screening methods are improving but remain inadequate, leaving the disease underdiagnosed and undertreated. The purpose of this study is to determine the effectiveness of an EMR implemented system that identifies patients at risk for osteoporosis via an OST (osteoporosis screening tool) score in prompting patients toward osteoporosis evaluation.

Methods:

OST scores are generated on every patient 50 years of age and older that is admitted to the Penn State Hershey Medical Center (PSHMC) and recorded in their electronic medical record. An OST score < 2 indicates that a patient has a potential risk for osteoporosis. Information Technology (IT) implemented the EMR OST calculation, which currently generates a daily filtered list of all patients with an OST score <2; patients with an OST score < 2 are then mailed letters approximately 3 months after their admission informing them of their risk for osteoporosis and suggesting that they schedule a follow-up appointment with a physician for further evaluation. To test the effectiveness of this system in prompting patients toward osteoporosis evaluation, approximately 3 months after letters were mailed, the patients were contacted via telephone and asked a series of questions to determine if the patients had sought osteoporosis evaluation.

Results:

In the intervention group, 67 (58.26%) of 115 did not schedule a follow-up, while the remaining 48 (41.74%) did seek a follow-up. Thus, the patient follow-up response rate improved with letter intervention using the OST score as an indicator (P < .0001) compared to historical controls (14.29%).

Conclusion:

Implementing an EMR OST score which identifies patients at risk for osteoporosis, which generates an automatic letter to the patient, significantly promotes patient driven osteoporosis evaluation compared to historical controls.

Helicobacter pylori Related Diseases and Osteoporotic Fractures (Narrative Review)

Osteoporosis (OP) and osteoporotic fractures (OFs) are common multifactorial and heterogenic disorders of increasing incidence. Helicobacter pylori (H.p.) colonizes the stomach approximately in half of the world's population, causes gastroduodenal diseases and is prevalent in numerous extra-digestive diseases known to be associated with OP/OF. The studies regarding relationship between H.p. infection (HPI) and OP/OFs are inconsistent. The current review summarizes the relevant literature on the potential role of HPI in OP, falls and OFs and highlights the reasons for controversies in the publications. In the first section, after a brief overview of HPI biological features, we analyze the studies evaluating the association of HPI and bone status. The second part includes data on the prevalence of OP/OFs in HPI-induced gastroduodenal diseases (peptic ulcer, chronic/atrophic gastritis and cancer) and the effects of acid-suppressive drugs. In the next section, we discuss the possible contribution of HPI-associated extra-digestive diseases and medications to OP/OF, focusing on conditions affecting both bone homeostasis and predisposing to falls. In the last section, we describe clinical implications of accumulated data on HPI as a co-factor of OP/OF and present a feasible five-step algorithm for OP/OF risk assessment and management in regard to HPI, emphasizing the importance of an integrative (but differentiated) holistic approach. Increased awareness about the consequences of HPI linked to OP/OF can aid early detection and management. Further research on the HPI-OP/OF relationship is needed to close current knowledge gaps and improve clinical management of both OP/OF and HPI-related disorders.

Few fragility fracture patients perceive that their bone health is affected by their comorbidities and medications

We examined fragility fracture patients' perceptions of associations between bone health and other chronic conditions and medications. Awareness of the associations between bone health and these conditions and medications was low. Providers should increase patients' awareness of these associations in order to minimize the risk of future fracture.

INTRODUCTION

Among patients with a fragility fracture presenting with at least one other chronic health condition, we examined (1) perceptions of the association between bone health and their other health conditions, and (2) perceptions of the association between bone health and prescribed medications taken for other health conditions.

METHODS

We identified fragility fracture patients presenting to a Canadian urban fracture clinic with at least one self-reported chronic health condition (in addition to bone fragility). In-depth interviews, 60-90 min in duration, were conducted. Our qualitative methodology was informed by saliency analysis.

RESULTS

We interviewed 26 patients (21 females, 5 males) aged 45 to 84 years old. Participants were taking 1-13 medications each and presented with a variety of comorbidities (range 1-7). All participants described at least one condition or medication they were currently taking for which there existed evidence of a negative effect on bone health (increased risk of fracture, bone loss, falling). Two participants perceived a correct association between their other health conditions and compromised bone health, and four participants perceived a correct association between their medications and compromised bone health.

CONCLUSION

All patients reported a chronic health condition and/or were taking at least one medication that potentially compromised their bone health. Patient awareness of the association between bone health and other health conditions and prescribed medications was low. Health care providers should increase patients' awareness of the bone health significance of their chronic conditions and medications in order to minimize the risk of future fracture.

[Diagnostics and treatment of osteoporosis in patients over 65 years old : Current status and future perspectives]

Only one third of all women with osteoporosis over the age of 65 years are adequately treated; therefore, many experience fractures. For men the data are insufficient. Using a newly developed algorithm and based on the current guidelines, the diagnosis and specific treatment of osteoporosis can be easily set up. The differential treatment should be selected in an individualized approach based on the side effect profile of the specific medication. No statistically significant differences were found between most specific osteoporotic drugs in head-to-head comparisons. This article presents an overview of the currently available pharmaceutical and non-pharmaceutical forms of treatment as well as approaches with novel medications and interventions for a better control of osteoporosis.

Biological secondary contributors to osteoporosis in fractured patients, is an early systematic assay relevant?

OBJECTIVE

To evaluate the prevalence of biological abnormalities leading to secondary osteoporosis in recently fractured patients.

METHODS

Adults older than 50, hospitalized for a non-vertebral fracture from July 2015 to October 2016, were assessed for bone fragility contributors in the orthopedics department. Bone mineral density (BMD) measurements and vertebral fracture assessment (VFA) were performed within 3 months. We assessed the prevalence of biological abnormalities in all the patients with recent fracture and in subgroups.

RESULTS

Among 439 hospitalized patients for non-vertebral low trauma fracture, 372 had biological tests (285 women, mean age 77.5 ± 13 years) and 353 (94.6%) had at least ≥ 1 biological abnormality, most frequently vitamin D insufficiency (< 75 nmol/L) (80%). Hypercalcemia was found in 22 (7.7%) patients, explained by possible primary hyperparathyroidism in 6 cases, and by the other causes of hypercalcemia including postoperative low albumin. A high PTH level was observed in 64 (20.8%) patients. We found 3 monoclonal bands. Results were similar in patients with and without vertebral fracture or osteoporosis. Finally, many biological abnormalities can be explained by the postoperative context (low TSH, hypogammaglobulinemia, low albumin, low alkaline phosphatase) and need a control.

CONCLUSION

This study performed in patient with recent low trauma non-vertebral fractures showed that 94.6% of patients had at least one contributor to bone fragility, which was the vitamin D insufficiency in most of cases. We found a high proportion of biological abnormalities which require additional explorations but most of them can be explained by the postoperative context.

Fracture Prevention in the Orthopaedic Environment: Outcomes of a Coordinator-Based Fracture Liaison Service

BACKGROUND

Fracture liaison services focus on secondary fracture prevention by identifying patients at risk for future fracture and initiating appropriate evaluation, risk assessment, education, and therapeutic intervention. This study describes key clinical outcomes including bone mineral densitometry, physician assessment, and pharmacotherapy initiation in pharmacotherapy-naïve patients undergoing treatment for fragility fracture in a Canadian fracture liaison service.

METHODS

We determined rates of post-fracture investigation and treatment for inpatients and outpatients with a fragility fracture seen in a coordinator-based fracture liaison service at an urban university trauma hospital. The program identified distal radial, proximal femoral, proximal humeral, and vertebral fragility fractures in female patients ≥40 years of age and male patients ≥50 years of age and provided education, bone mineral densitometry, inpatient consultation or outpatient specialist or primary care physician referral for bone health management, and documented patient follow-up.

RESULTS

The 2,191 patients with a fragility fracture were not taking anti-osteoporosis pharmacotherapy at the time of identification (862 inpatients and 1,329 outpatients). Eighty-four percent of inpatients and 85% of outpatients completed a bone mineral densitometry as recommended. Fifty-two percent of patients with proximal femoral fracture, 29% of patients with vertebral fracture, 26% of patients with proximal humeral fracture, and 20% of patients with distal radial fracture had osteoporosis confirmed on the basis of a bone mineral densitometry T-score of ≤-2.5 at the femoral neck or L1 to L4. Eighty-five percent of inpatients and 79% of outpatients referred for bone health management were assessed by a specialist or primary care physician. Of the patients who attended their appointments, 73% of inpatients and 52% of outpatients received a prescription for anti-osteoporosis medication.

CONCLUSIONS

A high rate of education, evaluation, and pharmacological treatment, if indicated, can be achieved through a coordinator-facilitated fracture liaison service program.

CLINICAL RELEVANCE

Fracture prevention programs are currently engaged in establishing and modifying fracture liaison services in a quest for practical and effective models. The program described in this article exemplifies a coordinator-based model that produced good outcomes.

Surgery alters parameters of vitamin D status and other laboratory results

Fracture liaison services often perform laboratory testing, but these results may be altered by surgery. In 40 hip arthroplasty patients, many laboratory parameters of bone health relevance were reduced by 8-22% on the first post-operative day. Laboratory results obtained in the immediate post-surgery interval do not reliably ascertain baseline status.

INTRODUCTION

As secondary causes of osteoporosis are common, fracture liaison services often perform laboratory testing in the immediate post-fracture interval. We hypothesized that laboratory results obtained shortly after surgery may not accurately ascertain baseline status. If true, such alterations might confound subsequent fracture prevention efforts.

METHODS

Patients undergoing elective total hip arthroplasty were studied as a surrogate for hip fracture patients. Blood and urine were obtained 2 weeks before surgery, before anesthetic induction, on post-operative day one, and 6 weeks after surgery. Serum total and free 25-hydroxyvitamin D (25(OH)D), vitamin D-binding protein (DBP), calcium, creatinine, albumin (Alb), alkaline phosphatase (ALP), plasma hemoglobin (Hgb) and urinary DBP/creatinine ratio (UDBP/Cr) were measured.

RESULTS

Forty volunteers (28 women; 12 men) with mean age of 65.7 [8.7] years were studied. Laboratory results were stable from 2 weeks before to the day of surgery. On the first day after surgery, total 25(OH)D, DBP, calcium, creatinine, ALP, and Alb declined 8-22% (p < 0.0001); free 25(OH)D and Hgb declined by 8 and 15% (p < 0.01), respectively; and UDBP/Cr increased 32% (p < 0.01). Using a 25(OH)D <30 ng/mL threshold, vitamin D inadequacy prevalence increased from 38% before surgery to 68% the day after (p < 0.001). All laboratory values returned to baseline at 6 weeks after surgery.

CONCLUSIONS

Laboratory values are reduced immediately following elective total hip arthroplasty. Testing at that time does not accurately ascertain baseline status and may lead to elevated estimates of vitamin D inadequacy, incorrect interventions, and misallocation of healthcare resources.

What Is the Role of Vitamin D Supplementation in Acute Fracture Patients? A Systematic Review and Meta-Analysis of the Prevalence of Hypovitaminosis D and Supplementation Efficacy

OBJECTIVES

The objectives of this systematic review and meta-analyses are (1) to estimate the prevalence of hypovitaminosis D in fracture patients and (2) to summarize the available evidence on the efficacy of vitamin D supplementation in fracture patients.

DATA SOURCES

A comprehensive search of the MEDLINE, Embase, PubMed, and Cochrane Central Register of Controlled Trials databases was conducted. Conference abstracts from relevant meetings were also searched.

STUDY SELECTION

We included studies that investigate vitamin D insufficiency or examine the effect of vitamin D supplementation on 25-hydroxy-vitamin D (25(OH)D) serum levels in fracture patients.

DATA EXTRACTION

Two authors independently extracted data using a predesigned form.

DATA SYNTHESIS

We performed a pooled analysis to determine the prevalence of postfracture hypovitaminosis D and mean postfracture 25(OH)D levels. We present detailed summaries of each of the studies evaluating the impact of vitamin D supplementation.

RESULTS

The weighted pooled prevalence of hypovitaminosis D was 70.0% (95% confidence interval: 63.7%-76.0%, I = 97.7). The mean postfracture serum 25(OH)D was 19.5 ng/mL. The studies that evaluated the efficacy of vitamin D supplementation suggest that vitamin D supplementation safely increases serum 25(OH)D levels. Only 1 meeting abstract showed a trend toward reduced risk of nonunion after a single large loading dose of vitamin D.

CONCLUSIONS

This review found a high prevalence of hypovitaminosis D in fracture patients and that vitamin D supplementation at a range of doses safely increases 25(OH)D serum levels. To date, only 1 pilot study published as a meeting abstract has demonstrated a trend toward improved fracture healing with vitamin D supplementation.

Osteoporosis and Low Bone Mineral Density in Men with Testosterone Deficiency Syndrome

INTRODUCTION

Testosterone deficiency syndrome (TDS) is a risk factor for low bone mineral density (BMD) and osteoporosis. Knowledge of the relationship between TDS and bone health, as well as the practical aspects of how to diagnose and treat low BMD, is therefore of practical importance to sexual medicine practitioners.

AIM

The aim of this study was to review the physiologic basis and clinical evidence of the relationship between TDS and bone health; and to provide a practical, evidence-based algorithm for the diagnosis and management of low BMD in men with TDS.

METHODS

Method used was a review of relevant publications in PubMed.

MAIN OUTCOME MEASURES

Pathophysiology of low BMD in TDS, morbidity, and mortality of osteoporosis in men, association between TDS and osteoporosis, indications for dual X-ray absorptiometry (DXA) scanning in TDS, evidence for testosterone replacement therapy (TRT) in men with osteoporosis, treatment for osteoporosis in the setting of TDS.

RESULTS

Sex hormones play a pleomorphic role in maintenance of BMD. TDS is associated with increased risk of osteoporosis and osteopenia, both of which contribute to morbidity and mortality in men. DXA scanning is indicated in men older than 50 years with TDS, and in younger men with longstanding TDS. Men with TDS and osteoporosis should be treated with anti-osteoporotic agents and TRT should be highly considered. Men with osteopenia should be stratified by fracture risk. Those at high risk should be treated with anti-osteoporotic agents with strong consideration of TRT; while those at low risk should be strongly considered for TRT, which has a beneficial effect on BMD.

CONCLUSION

Low BMD is a prevalent and treatable cause of morbidity and mortality in men with TDS. Utilization of a practical, evidence-based approach to diagnosis and treatment of low BMD in men with TDS enables sexual medicine practitioners to make a meaningful impact on patient quality of life and longevity.

Secondary osteoporosis and metabolic bone disease in patients 50 years and older with osteoporosis or with a recent clinical fracture: a clinical perspective

PURPOSE OF REVIEW

The purpose of this review is to provide guidance to clinicians about which laboratory tests should be performed in patients with osteoporosis or with a recent fracture.

RECENT FINDINGS

Newly diagnosed secondary osteoporosis and other metabolic bone diseases (SECOB) have been found in 5-48% of patients with osteoporosis. In patients with a recent fracture, new SECOB is found in 10-47% of patients with osteoporosis, and in 26-51% if all patients with a fracture regardless of bone mineral density (BMD) are screened. More than one SECOB can be found in the same patient, even when they have already known SECOB. In primary hyperparathyroidism, hyperthyroidism, hypercortisolism, and multiple myeloma, both SECOB and its treatment have an impact on BMD and fractures. For other SECOBs, no treatment is available, or there are no data about the effect of treatment of the SECOB on BMD and fractures.

SUMMARY

We recommend performing the following tests in all patients with osteoporosis or a recent clinical fracture: calcium, phosphate, creatinine, albumin, erythrocyte sedimentation rate in all patients, 24 h urine calcium in men and serum testosterone in men less than 70 years. On indication, additional tests can be performed.

Yield and cost-effectiveness of laboratory testing to identify metabolic contributors to falls and fractures in older persons

Falls and fractures constitute a major cause of morbidity and mortality among older adults. Although falls and fractures share similar risk factors, there is no integrated approach to identifying secondary causes of both entities. We report a cost-effective approach to identify metabolic causes of falls and fractures in the clinical setting.

PURPOSE

Falls and fractures are a major cause of morbidity and mortality among older adults. Metabolic disorders contributing to the combined risk of falls and fractures are frequent but often go undetected. The most efficient and cost-effective laboratory screening strategy to unmask these disorders remains unknown. The purpose of this study was to identify the most cost-effective laboratory tests to detect undiagnosed metabolic contributors and to decide treatment of these disorders in older persons.

METHODS

This is a cross-sectional study design, which included all participants attending the Falls & Fractures Clinic, Nepean Hospital (Penrith, Australia) between 2008 and 2013. Chemistry profile included 25(OH) vitamin D, parathyroid hormone (PTH), albumin, creatinine, calcium, phosphate, vitamin B-12, folate, and thyroid-stimulating hormone (TSH) for all patients, and serum testosterone in men. The number of new diagnoses identified and their cost-effectiveness (cost in US$ per patient screened and cost per new diagnosis) were calculated.

RESULTS

A total of 739 participants (mean age 79, 71 % female) were assessed. Among 233 participants with complete laboratory tests, previously undiagnosed disorders were identified in 148 (63.5 %). Vitamin D deficiency (27 %) and hyperparathyroidism (21.5 %) were the most frequent diagnoses. A testing strategy including serum vitamin D, calcium, PTH, creatinine/estimated glomerular filtration rate (eGFR), and TSH for all patients and serum testosterone in men would have been sufficient to identify secondary causes of falls and fractures in 94 % of patients at an estimated cost of $190.19 per patient screened and $257.64 per diagnosis.

CONCLUSIONS

The minimum cost-effective battery for occult metabolic disorders in older adults at risk of falls and fractures should include serum vitamin D, PTH, TSH, creatinine/eGFR, testosterone (in men), and calcium.

Establishing a fracture liaison service: an orthopaedic approach

➤ Bone health evaluations should be incorporated into care pathways for fragility fractures in all patients who are fifty years of age or older.➤ A fracture liaison service (FLS) is an established and proven method to achieve recommended standards of care for fragility fractures, including intervention for osteoporosis, secondary fracture prevention, and bone health evaluation.➤ The FLS facilitates patient care by automatically including all patients with a fragility fracture within a health-care system to provide them with the intervention that they need and to prevent avoidable fracture-related complications or readmissions.➤ An FLS functions with three key personnel: the FLS coordinator (usually an advanced practice provider), a physician champion (usually an orthopaedic surgeon), and a nurse navigator.

Secondary confounders of osteoporotic hip fractures in patients admitted to a geriatric acute care department

BACKGROUND

With respect to the pathogenesis of osteoporosis, primary and secondary forms of the disease can be distinguished. It has been recognized that the incidence of primary and secondary osteoporosis differs in women and men.

OBJECTIVE

The aim of the present study was to assess the incidence and gender distribution of factors contributing to osteoporosis in older hip fracture patients.

METHODS

In this cross-sectional study 404 patients with hip fractures and controls referred to an acute geriatric care department over a period of 15 months were included. The medical history was recorded and blood samples were analyzed for routine laboratory parameters.

RESULTS

A total of 249 patients with hip fractures and 155 matched controls were studied. The Tinetti test and the Barthel index were found to show highly significant differences in both groups mainly because of the postoperative state of patients with fractures. Vitamin D deficiency was found in 94.1% of male fracture patients and 94.6% of female fracture patients. On average 2.4 secondary contributors of osteoporosis were present in male fracture patients versus 2.9 in male controls and 2.3 in female fracture patients versus 2.3 in female controls. For most parameters no significant gender differences of possible secondary contributors to osteoporosis were found. Secondary osteoporosis was diagnosed in all male fracture patients and in 56.2% of all female fracture patients.

CONCLUSION

Based on the findings of this study it is recommended that hip fracture patients should be assessed for secondary contributors of osteoporosis. Although the overall distribution of secondary contributors was similar in women and men, the prevalence of secondary osteoporosis was higher in men.

Incidence of Vitamin D Insufficiency in Coastal South-Eastern US Patient Population With Cardiovascular Disease

Background

Vitamin D insufficiency is increasingly gaining prominence as an associated cardiovascular disease (CVD) risk factor, often thought to be an issue in colder climates and higher altitudes. The intent of this study was to ascertain vitamin D levels in the southern Alabama gulf-coast region that has a high number of sunny days along with an annual average elevated UV ray index.

Methods

An observational retrospective study of 204 patients with established CVD treated at the University of South Alabama’s Heart Center from January 2007 through January 2013 was undertaken. One-way ANOVA analyses were performed to determine any significant difference in the mean 25-hydroxyvitamin D (25(OH)D) serum based on gender and also based on race/ethnicity. Further, odds ratio (OR) was computed to ascertain if there was a relationship between vitamin D insufficiency and elevated body mass index (BMI).

Results

Out of 204 patients, 53.4% (n = 109) were found to have vitamin D insufficiency (25(OH)D = 20.1 ng/mL), while 46.6% (n = 95) were within the normal range (25(OH)D = 37.8 ng/mL). The mean 25(OH)D of the entire group was 28.3, indicating a general trend of vitamin D insufficiency for patients treated at the cardiology clinics.

Conclusion

This study established the prevalence of vitamin D insufficiency in the hot and high UV ray index climate of the coastal south-eastern United States. Also, it revealed the relationship of increased BMI with low 25(OH)D serum level. More extensive studies should be conducted in similar climates to further assess vitamin D insufficiency.

Osteoporosis and its complications

This article provides an overview of the current burden of osteoporosis and its complications in today's health care system. The impact of osteoporosis on patients' quality of life and direct financial consequences to the entire health care system are emphasized to highlight the need for increased knowledge and awareness of its complications if left untreated or treated incorrectly. Special attention is given to hip fracture and vertebral compression fracture, stressing the importance of diagnosing osteoporosis before fragility fractures occur. Models for improved care of fragility fractures during follow-up in the outpatient setting and the use of pharmacologic agents are discussed.

Patients' response toward an automated orthopedic osteoporosis intervention program

Osteoporosis is overshadowed in an era of chronic illnesses, and a care gap exists between physicians and patients. The aim of this study was to determine the effectiveness of implementing an automated system for identifying and sending a letter to patients at high risk for osteoporosis. Patients 50 years of age and older were tagged with an International Classification of Diseases, Ninth Revision, diagnostic code upon initial visit to the emergency department (ED), identifying potential fragility fractures. Automatically generated letters were sent via our osteoporosis database system to each patient 3 months after the initial visit to the ED. The letter indicated that he or she was at risk for osteoporosis and suggested that the patient schedule a follow-up appointment with a physician. Patients were subsequently telephoned 3 months after receiving the letter and asked about their current plan for follow-up. The control group did not receive a letter after departure from the ED. In the control group, 84 (85.71%) individuals of the total 98 did not have any follow-up but the remaining 14 (14.29%) sought a follow-up. In the intervention group, 62 (60.19%) individuals of 103 did schedule a follow-up, while the remaining 41 (39.81%) did not seek a follow-up. Thus, the patient follow-up response rate after fracture treatment improved with intervention (P < .0001). Current literature has demonstrated the low rate of follow-up care addressing osteoporosis in patients experiencing fragility fractures (1%-25% without intervention). Research has shown the effectiveness of various types of intervention programs for improving the continuum of care for these high-risk patients. Nonautomated intervention programs can have a multitude of human-related system failures in identifying these patients. Our study successfully implements an automated system that is able to be applied to most hospitals with minimal cost and resources.

Comprehensive classification of fragility fractures of the pelvic ring: Recommendations for surgical treatment

Due to the increasing life expectancy, orthopaedic surgeons are more and more often confronted with fragility fractures of the pelvis (FFPs). These kinds of fractures are the result of a low-energy impact or they may even occur spontaneously in patients with severe osteoporosis. Due to some distinct differences, the established classifications for pelvic ring lesions in younger adults do not fully reflect the clinical and morphological criteria of FFPs. Most FFPs are minimally displaced and do not require surgical therapy. However, in some patients, an insidious progress of bone damage leads to increasing displacement, nonunion and persisting instability. Therefore, new concepts for surgical treatment have to be developed to address the functional needs of the elderly patients. Based on an analysis of 245 consecutive patients with FFPs, we propose a novel classification system for this condition. This classification is based on morphological criteria and it corresponds with the degree of instability. Also in the elderly, these criteria are the most important for the decision on the type of treatment as well as type and extent of surgery. The estimation of the degree of instability is based on radiological and clinical findings. The classification gives also hints for treatment strategies, which may vary between minimally invasive techniques and complex surgical reconstructions.

A Case with Multiple Punched-out Lesions in the Skull and Generalized Fractures Associated with Steroid-induced Osteoporosis

Steroid-induced osteoporosis is the most common cause of secondary osteoporosis and accounts for one-fifth of all osteoporosis cases. The fracture incidence under steroid may be as high as 50%. However, many patients do not undergo appropriate risk assessment and treatment before and after steroid exposure. We described a 56-year-old male patient with multiple punched-out lesions in skull unusually as well as vertebral, fibular, rib and humeral fractures during steroid use without proper management.

Adding to complexity: comorbidity in paediatric rheumatic disease

Novel therapies including biologic agents offer paediatric rheumatologists significant opportunity to improve long-term prognosis for children with rheumatic disease. However, comorbidities related to the diseases themselves and their treatments pose specific challenges to be overcome. Prompt recognition and appropriate management will improve quality of life, effectiveness of treatment and overall prognosis. In this review, we discuss key areas of comorbidity frequently encountered in paediatric rheumatology including cardiovascular, renal, genito-urinary and visual comorbidity, bone health, drug-related issues and the influence of rheumatic disease on growth and puberty.

Unrecognized and unappreciated secondary causes of osteoporosis

There are a substantial number of secondary causes of osteoporosis that can be identified through appropriate evaluation. Unrecognized celiac disease, Monoclonal gamopathy of undetermined significance (MGUS), impaired renal function, diabetes mellitus, and renal tubular acidosis are just a few of the more common secondary causes of osteoporosis. Through targeted laboratory tests, many secondary causes of osteoporosis can be identified.
