Diabetes mellitus type 2 (T2DM) is an emerging public health issue with high prevalence rates among older adults while fragility fractures constitute a significant public health burden with a great impact. Osteoporosis is the most important metabolic bone disease in patients with diabetes mellitus. Based on current evidence, individuals with T2DM are more vulnerable to fragility fractures than their non-diabetic counterparts, although until now, there aren't any systematic reviews or meta-analyses concerning the impact of T2DM on the risk of fragility fractures in elderly patients. The aim of this study is to fill this gap in the current literature concerning this specific patient group.Literature in PubMed and Google Scholar was searched for relevant articles published up to January 2021. The keywords used were: elderly, diabetes mellitus type 2, and fragility fractures. Among the 180 articles retrieved, only four full-text articles were eligible and, finally, two studies (one population-based cohort study and one cross-sectional study) met the inclusion criteria for the review. Although we identified 15 records through the manual research, finally 17 records were included in the current review. The records retrieved from the manual research were 11 prospective cohort studies, two population-based studies, one prospective observational study, and one retrospective cohort study. The author's name, year of publication, country, type of study, and number of patients were reported.According to this systematic review, there is almost consensus about the increased prevalence of all kinds of fragility fractures and especially low-energy hip fractures among elderly patients with T2DM compared with their counterparts without T2DM while there is relative controversy concerning non-vertebral fractures. Vertebral fractures in the elderly with T2DM require further evaluation because the results from cohort studies are more conflicting. Finally, insulin usage can increase the possibility of fragility fractures and can even double this risk. Bone fragility should be recognized as a new complication of T2DM, especially in elderly patients, due to several additional aggravating factors such as senile osteoporosis, severe vitamin D deficiency, presence of many comorbidities, increased possibility of insulin usage, and the presence of diabetes-related complications (mainly neuropathy and retinopathy). Clinicians who treat these patients should be aware of the special diagnostic and therapeutic approaches concerning these patients.
Diabetes mellitus type 2 (T2DM) is an emerging public health issue with high prevalence among older adults (>60 years old). Taking into consideration the great increase in the elderly population (approximately 7.5 billion worldwide), we can easily understand the impact of this chronic disease and its complications. On the other hand, vitamin D deficiency (VDD) is also a serious public health problem with significant impacts and multiple health effects. The correlation between DM and VDD has been suggested and established from many observational studies, reviews, and meta-analyses. The literature in PubMed and Google Scholar was searched for relevant articles published up to October 2020. The keywords used were the following: vitamin D deficiency, elderly, and diabetes mellitus type 2. Among the 556 articles retrieved, 90 full texts were eligible and only 34 studies (12 retrospective studies, two prospective cohorts, three meta-analyses, seven cross-sectional studies, nine randomized control trials (RCTs), and one observational study) met the inclusion criteria for the review. The author's name, year of publication, country, type of study, and the number of patients were reported. According to this review there is adequate evidence to support the correlation between VDD and T2DM in the elderly. The results from the RCTs are more conflicting and more studies are needed to confirm the impact of vitamin D deficiency (VD) supplementation on metabolic and lipid profile, oxidative stress, and the complications of T2DM in older patients. VDD is clearly related with severe retinopathy, diabetic peripheral neuropathy, and poor cognition performance, while there is consensus about the beneficial effect of VD on peripheral artery disease, foot ulceration prevention, and wound healing. On the other hand, there is controversy about the effect of VD supplementation on cardiovascular adverse events, endothelial function, and estimated glomerular filtration rate (eGFR). Finally, the association of VDD with fragility fractures and depression in the elderly with T2DM is currently insufficiently studied and remains controversial.
Plasmacytomas are malignant tumors characterized by abnormal monoclonal proliferation of plasma cells. They originate either from bone or soft tissue and could be primary or a part of a systemic process during the course of multiple myeloma. Extramedullary plasmacytomas (EPs) in the sinonasal tract or nasopharynx are rare and mostly presented as case reports. We describe a unique case of multiple myeloma involving the nasal cavity and the paranasal sinuses with osteolytic expansile lesions of the first cervical vertebrae (atlas), the clavicle, and the skull in a 51-year-old man. The diagnostic approach was challenging, and finally the biopsy of the extramedullary tumor settled the diagnosis of multiple myeloma. The patient underwent posterior occipitocervical fusion due to upper cervical spine instability due to atlas osteolysis. The patient had an uneventful recovery, and he was finally referred to the hematology department. EP of the nasal cavity is a rare entity and requires a high index of suspicion. EP should be included in the differential diagnoses of nasal cavity masses, especially in males in the age group of 50-60 years. A thorough clinical history, examination, and proper laboratory and radiological investigations are important to settle an accurate diagnosis to initiate treatment as soon as possible. Timely diagnosis ensures a better prognosis and deters the progression of the disease.
Ceramic head fracture is a major complication of ceramic-on-ceramic (CoC) total hip arthroplasty (THA) and though new generation ceramics have lowered the rates, although it is still a great concern. We report a case of late onset (more than 10 years after surgery) ceramic head fracture of a hybrid ceramic bearings to emphasize on its unusual clinical manifestation. Furthermore, we highlight the late onset presentation and also the rarity of this complication with this particular hybrid ceramic bearings. A relevant review of the literature revealed that hybrid ceramic bearings need to be more thoroughly studied to understand modes of their failure and to reach a consensus on how to reduce and prevent these disastrous complications.
Bisphosphonates (BPs) are the mainstay of osteoporosis treatment due to their safety and efficacy. There is evidence that BPs medication may be complicated by atypical femoral fractures (AFFs). Prolonged administration of BPs is even more strongly associated with AFFs. AFF is a relatively rare complication of BPs when taking into account the huge population worldwide that benefits from this pharmacotherapy. AFF is, however, a serious complication of BPs treatment, which includes prolonged healing time and high revision rate when operative treatment is required. Less frequently, AFFs occur even without BPs administration, while these fractures have all the characteristics of “stress” or “insufficiency” fractures. The critical point of view in AFFs pathogenesis seems to be not only the biology of cortical bone, but also the mechanical issue. It has been proven that BPs, glucocorticoids and proton pump inhibitors (PPIs) can cause bone turnover suppression and affect the biological parameter of AFFs pathogenesis. Specific mechanical femoral bone properties predispose to AFFs pathogenesis. Several studies have already reported that increased femoral bowing > 5.25 0 degrees or decreased femoral neck-shaft angle <125 degrees, are associated with increased risk for diaphyseal and subtrochanteric AFFs respectively, regardless of BPs uptake. If these two parameters are simultaneously present, the probability for AFFs occurrence increases dramatically. Our scientific report, which is based on the current evidence about AFFs, is that if both femoral bowing angle and femoral neck-shaft angle are evaluated before BPs administration, this intervention may reduce the incidence of AFFs. Thus, in cases with excessive lateral femoral shaft bowing or very small femoral neck-shaft angle, the prescription of another anti-osteoporotic treatment than BPs should be recommended. If, however, BPs can’t be avoided, clinicians should be aware of the fact that long-term administration may be implicated with AFFs occurrence. In these cases, short term BPs administration with timely drug holiday between three and five years may be reasonable. Finally, roentgenographic evaluation of both femurs every six months and medical reference in case of any emerging thigh pain are also logical interventions to prevent and reduce AFFs.
