“…DXA allows accurate diagnosis of osteoporosis, helps to determine the estimate fracture risk and monitoring of patients undergoing treatment (1)(2)(3)(4)(5). The primary target of DXA is to quantify BMD accurately and reproducibly and to compare that measurement with a reference population of asymptomatic individuals.…”

“…Low measurement values on DXA predict the risk of fractures of the spine and hip, analogous to the relationship between high serum cholesterol and the risk of heart disease, or between high blood pressure and the risk of stroke. DXA is also useful in evaluating the effectiveness of FDA-approved therapies for osteoporosis, such as alendronate, risedronate, and raloxifene (1,2,(4)(5)(6).…”

Summary:Background: Osteoporosis is a widespread metabolic bone disease representing a global public health problem currently affecting more than two hundred million people worldwide. The World Health Organization states that dual-energy X-ray absorptiometry (DXA) is the best densitometric technique for assessing bone mineral density (BMD). DXA provides an accurate diagnosis of osteoporosis, a good estimation of fracture risk, and is a useful tool for monitoring patients undergoing treatment. Common mistakes in BMD testing can be divided into four principal categories: 1) indication errors, 2) lack of quality control and calibration, 3) analysis and interpretation errors, and 4) inappropriate acquisition techniques. The aim of this retrospective multicenter descriptive study is to identify the common errors in the application of the DXA technique in Turkey. Methods: All DXA scans performed during the observation period were included in the study if the measurements of both, the lumbar spine and proximal femur were recorded. Forearm measurement, total body measurements, and measurements performed on children were excluded. Each examination was surveyed by 30 consultants from 20 different centers each informed and trained in the principles of and the standards for DXA scanning before the study. Results: A total of 3,212 DXA scan results from 20 different centers in 15 different Turkish cities were collected. The percentage of the discovered erroneous measurements varied from 10.5% to 65.5% in the lumbar spine and from 21.3% to 74.2% in the proximal femur. The overall error rate was found to be 31.8% (n = 1021) for the lumbar spine and 49.0% (n = 1576) for the

Objective: Vitamin D deficiency has become an epidemic for all age groups in the world. The aim of this research is to evaluate the vitamin D deficiency in-home care patients and related lifestyle reasons. Method: This research is done on Home Care patients registered to İstanbul Şişli Hamidiye Etfal Training and Research Hospital between January 2015 – February 2016. After getting the patients’ vitamin D records retrospectively, we have inquired patients if they have regular exposure to sunlight, whether they have a history of fracture or osteoporosis, and other related lifestyles.D vitamin deficiency was grouped as; normal(>30ng/ml), insufficiency(20-30ng/ml), deficiency(lower than 20ng/ml)and the severe deficiency(lower than <10ng/ml). We used the SPSS20.0 program; frequency, chi-square, and T-test were evaluated. Results: Totally 232 patients were included in this study. There were 160(%69) women and 72 (%31) men. Vitamin D insufficiency was found in 11.2% (n=26), and vitamin D deficiency in 70.3% (n=163). 70.1% (n=96) of 137 patients who answered the questions were female and 29.9% (n=41) were male. 86.1% of them (n=118) did not benefit from sunlight, 63.5% (n=87) had not received vitamin D treatment before. Vitamin D deficiency was detected in 79.3% (n=69) of those who did not receive vitamin D treatment, and a significant relationship was found between them. Conclusion: In our study, we have found that most homecare patients have low levels of Vitamin D, do not have regular exposure to sunlight, not do exercise regularly. Vitamin D replacement is vital in home-care patients as vitamin D deficiency increases the risk of osteoporosis, falls, and fractures.

Bu çalışmanın amacı Nükleer Tıpta tanı ve tedavi amacıyla kullanılan İyot-131 (I-131) ve Flor-18 (F-18) radyonüklidlerinden salınan yüksek enerjili gama ışınlarının DEXA çekimlerinde kemik mineral yoğunluğu (BMD) üzerine etkisinin araştırılmasıdır. Yöntem: DEXA yöntemi ile kalite kontrol fantomunda L1-L4 vertebralardan kemik mineral yoğunluğu ölçümleri yapılarak referans BMD değerleri belirlendi. Bir su tankı içine önce 0,5-5 mCi (18,5-185 MBq) arasında değişen miktarlarda I-131 konularak homojen karışım sağlandı. Sonra tankın üstüne vertebra fantomu konuldu. Deney düzeneğinde sadece radyonüklid aktivitesi değiştirilip diğer geometrik koşullar sabit tutularak toplam 6 kez çekim yapıldı. Daha sonra aynı işlemler F-18 radyonüklidi kullanılarak tekrarlandı. Bulgular: Referans BMD 1,00±0,05 gr/cm2, I-131 için tüm aktivitelerin ortalamasına göre BMD değeri 1,012 ± 0,034 gr/cm 2 F-18 için tüm aktivitelerin ortalamasına göre BMD değeri 1,016 ± 0,047 gr/cm bulundu. Sonuç: Sonuçlarımıza göre, tanı amaçlı I-131 (<6 mCi) ve F-18 radyonüklidlerine ait radyofarmasötik uygulamalarında aynı gün içinde DEXA çekimlerinin yapılabileceği, yüksek doz I-131 tedavi uygulamalarında ise radyasyon güvenliği yönünden 1 hafta sonra DEXA çekimlerinin yapılabileceği sonucuna varılmıştır.
