End-stage renal disease (ESRD) patients often experience accelerated bone turnover, leading to osteoporosis and osteopenia. This study aimed to determine the prevalence of osteoporosis in Peritoneal Dialysis (PD) patients using bone mineral density (BMD) measurements obtained through dual-energy X-ray absorptiometry (DEXA) scan and to explore any possible associations with clinical and biochemical factors. In this cross-sectional study, we enrolled 76 peritoneal dialysis patients from the dialysis center at An-Najah National University Hospital in Nablus, Palestine. We used the DEXA scan to measure BMD at the lumbar spine and hip, with values expressed as T-scores. We conducted a multivariate analysis to explore the relationship between BMD and clinical and biochemical parameters. Over half (52.6%) of the PD patients had osteoporosis, with a higher prevalence observed among patients with lower BMI (p<0.001). Higher alkaline phosphatase levels were found among osteoporotic patients compared to non-osteoporotic patients (p = 0.045). Vitamin D deficiency was also prevalent in this population, affecting 86.6% of patients. No significant correlation was found between 25 vitamin D levels and BMD. No significant correlation was found between Parathyroid hormone (PTH) levels and BMD. A notable proportion of PD patients experience reduced BMD. Our study found no correlation between vitamin D levels and BMD, but it highlighted the significant vitamin D deficiency in this population. Furthermore, our analysis indicated a positive correlation between BMI and BMD, especially in the femoral neck area. This underscores the significance of addressing bone health in PD patients to mitigate the risk of fractures and improve their overall well-being.

Background End-stage renal disease is a significant global health issue, and Peritoneal Dialysis (PD) is a vital treatment modality. The study aims to assess the Quality of Life (QoL) and pain levels in PD patients and explore potential influencing factors. Methods A cross-sectional study was conducted in 2022 involving 76 PD patients at a referral tertiary dialysis center in Palestine. The study evaluated patient demographics, clinical data, laboratory measures, quality of life as assessed by the KDQOL-SF36, and pain levels as determined by the Brief Pain Inventory. Statistical analyses, including multivariate linear regression, were employed to identify relevant associations. Results This study included 76 PD disease patients, with 68.4% being under the age of 60 and 53.9% being male. Almost one-third of the participants (34.0%) reported mild to severe pain, and 23.7% reported low to high interference levels. Pain severity was negatively correlated with supplement doses for both vitamin D3 ( p  = 0.049) and calcium ( p  < 0.01). Female patients reported higher pain severity ( p  = 0.001) and interference ( p  < 0.007) levels. The study revealed relatively higher QoL among our cohort of PD patients compared to previously published findings in similar settings, specifically for HD populations. Factors such as age, comorbid conditions, and duration of dialysis influenced QoL ( p  < 0.05). Pain severity and interference were negatively correlated with QoL ( p  = 0.01). Conclusion This study provides valuable insights into the QoL and pain experiences of PD patients in Palestine. It underscores the importance of effective pain management strategies and holistic care to improve QoL in this patient population. Addressing psychological and emotional well-being is vital for optimizing treatment adherence and long-term outcomes. Clinical trial number Not applicable.

Ewing’s sarcoma, a rare primary bone malignancy primarily affecting adolescents and young adults, typically manifests in the pelvic bones and femur. Primary Ewing’s sarcoma of the sternum is exceptionally rare, constituting less than 1% of cases. We present a case of a 34-year-old man with a 2-month history of anterior chest wall pain initially attributed to muscular spasm. Subsequently, the patient developed a palpable mass and imaging demonstrated a mid-lower sternal lesion with cortical destruction and soft tissue involvement, confirmed as Ewing’s sarcoma on biopsy. In addition, a suspicious lesion was identified in the left distal tibia, which was histologically confirmed as a metastasis from the primary sternal sarcoma. Neoadjuvant chemotherapy preceded partial sternotomy with rib resection and reconstruction, achieving clear surgical margins. Postoperative evaluation showed shrinkage in the sternal lesion and near-resolution of the tibial metastasis. Subsequent chemotherapy cycles resulted in no evidence of the disease on the follow-up positron emission tomography scan. This case underscores the diagnostic challenges of primary sternal Ewing’s sarcoma and emphasizes the importance of early recognition and comprehensive evaluation in managing such rare presentations.

SummaryDespite the high prevalence of osteoporosis and vitamin D deficiency, the knowledge about osteoporosis and vitamin D-related practices were moderate in some countries in the Middle East and North Africa (MENA) region. Improving knowledge through awareness campaign and screening programs is essential to enhance vitamin D-related practices.PurposeOsteoporosis is the most common skeletal disease, which usually remains silent until fractures occur. Vitamin D deficiency impairs bone mineralization and increases the risk of osteoporosis. Despite being relatively sunny, the Middle East and North Africa (MENA) region has a high prevalence of osteoporosis and hypovitaminosis D. This study aims to assess the knowledge about osteoporosis and vitamin D-related practices and to determine the correlation between them in some countries of the MENA region.MethodsA cross-sectional study was performed in Lebanon, Syria, Egypt, Palestine, Iraq, Jordan, and Saudi Arabia. From each country, 600 participants were enrolled. The survey included four sections: sociodemographic information, past medical history, Osteoporosis Knowledge Assessment Tool to assess the knowledge about osteoporosis, and Practice Towards Vitamin D scale to assess vitamin D-related practices.ResultsOur study found that 67.14% of respondents had moderate knowledge about osteoporosis and 42.31% had moderate vitamin D-related practices. Higher knowledge level was reported in the young, females, Syrians, singles, postgraduates, and healthcare employees (p < 0.05). Better vitamin D-related practices were detected in the elderly, males, Egyptians, married, and high school or below educational level (p < 0.05). The Internet was the most listed source of information. Adequate osteoporosis knowledge was associated with better vitamin D-related practices (p < 0.001).ConclusionMost participants, representing some countries of the MENA region, displayed moderate knowledge regarding osteoporosis and moderate vitamin D-related practices. Adequate knowledge about osteoporosis is essential to improve practices, so awareness campaigns and screening programs should be more frequently implemented.
