Item Bilateral Femoral Head Insufficiency Fractures and Multiple Vertebral Fractures: A Case Report on Rare Presentations of Pregnancy and Lactation-associated Osteoporosis and Their Outcomes(2020) Ozen, Selin; Yemisci, Oya Umit; Sozay, Seyhan; 0000-0002-7290-8558; 0000-0002-0501-5127; ABC-1305-2020Pregnancy and lactation-associated osteoporosis (PLO) is a rare condition seen in the last trimester of pregnancy and early puerperal period which can result in vertebral and femoral fractures. In this case report, two cases of fractures secondary to PLO, their management and clinical outcomes are presented. Case one describes a patient with vertebral fractures secondary to PLO who was treated with bisphosphonates. Case two describes a rare case of bilateral femoral head stress fractures secondary to PLO, treated with bed rest, a home exercise programme and calcium and vitamin D supplementations. Pharmacological treatment of PLO includes teriparatide and strontium ranelate and crossover treatments-all of which require the cessation of breastfeeding. The optimal PLO treatment remains to be determined. Further studies comparing the clinical and biological outcomes of these drugs are necessary so that clinicians can accurately advise women on the risks and benefits of each, for both themselves and their child and guide patients in making a suitably informed decision regarding treatment.Item Evaluation of bone mineral density and its associated factors in postpartum women(2019) Eroglu, Semra; Karatas, Gulsah; Aziz, Vusale; Gursoy, Aybala Fatma; Ozel, Sule; Gulerman, Hacer Cavidan; 31759531; AAD-8353-2020Objective: Although osteoporosis commonly appears among postmenopausal women, it is rarely diagnosed during the postpartum period as pregnancy-lactation associated osteoporosis (PAO). The aim of the study reported here was to investigate low bone mineral density and its associated risk factors in postpartum women. Materials and methods: The sample consisted of 93 females aged 18-40 years and in the first month of the postpartum period. All the women had low back pain. The bone mineral density (BMD) Z-score values of the lumbar vertebrae, femur (neck and total) were examined using dual energy x-ray absorbtiometry four weeks after birth. Patients body mass index (BMI), 25-hydroxyvitaminD (25-OHD) levels and complete blood counts were recorded. Participants were divided into two groups to their Z scores: the normal group (n = 71) and the low BMD group (n = 22). Results: The 25-OHD levels were significantly lower (p = .02) in the low BMD group [4.45 (4.0-12.4)] than in the control group [22 (12-48)], however, NLR and PLR values were similar between groups. BMI positively correlated with BMD scores for the lumbar, femoral neck and femoral overall (p = .011, p = .026 and p = .026, respectively). Conclusion: Vitamin D deficiency and BMI may play a critical role in PAO. Low back pain during postpartum period should be carefully evaluated. Adequate calcium and vitamin D supplementation may prevent possible bone loss. (C) 2019 Taiwan Association of Obstetrics & Gynecology.

A Cross-Sectional Clinical Study(2015) Yalbuzdag, Seniz Akcay; Sarifakioglu, Banu; Sengul, Ilker; Cetin, NuriObjective: In this study, we investigated the relationships between 10 year fracture risk calculated with FRAX assessment tool and bone turnover markers (BTM) in women with diagnosed as postmenopausal osteoporosis for the first time. Materials and Methods: After exclusion of the causes of secondary osteoporosis 61 postmenopausal women diagnosed with osteoporosis for the first time were enrolled. Height and weight measurements, comorbid diseases, menopause age, and laboratory investigations were recorded. Lumbar and femur neck and femur total T scores were measured by dual-energy x-ray absorptiometry (DXA). As BTM, serum osteocalcin (OC) and urine deoxypridinoline levels were measured. 10-year fracture risk of hip and major osteoporotic fracture was calculated with FRAX assessment tool. Results: The mean age of patients was 61 +/- 39 years. Median value of menopause year was 15.13 years (min: 2, max: 40). The median 10-year hip fracture and major osteoporotic fracture risks were calculated as 1.10% (min: 0, max: 23), 6.9% (min: 3, max: 34) respectively. There was no significant relationship between BTM and fracture risk. Positive significant correlation was found between menopause year and hip fracture risk, and between menopause year and major osteoporotic fracture risks (p=0.031, 0.276; p=0.025, r=0.287). Negative significant correlation was detected between body mass index and hip fracture risk (p=0.002, r=-0.392). Conclusion: In our study, we couldn't find relationship between BTM and fracture risks assessed by using FRAX tool in patients with initially diagnosed of postmenopausal osteoporosis. Further studies are needed to investigate the relationship between BTM and fracture risk in different patient groups.Item The effect of alendronate sodium on trabecular bone structure in an osteoporotic rat model(2017) Ozsahin, Esin Tokmak; Cam, Burcu; Dere, Fahri; Kurkcu, Mehmet; Evruke, Cuneyt; Soames, Roger; Oguz, Ozkan; 31453446Objectives: This study aims to investigate the effect of alendronate sodium on trabecular bone structure in an osteoporotic rat model. Materials and methods: Between May 2006 and July 2006, 60 female Wistar Albino rats aged three months were randomly allocated to three groups: sham operated receiving no treatment (Shm); ovariectomized-alendronate receiving 1 mg/kg/day alendronate sodium (Ovx-A), and ovariectomized-vehicle receiving 1 mL/kg/day physiological saline (Ovx-PS). Both Ovx groups received treatment through gastric gavage for 56 days. Results: Densitometric measurements showed that bone mineral density decreased in the Ovx-PS and increased in Ovx-A groups (p<0.05). Biomechanical measurements showed a decrease in the breaking force in the Ovx-PS group and an increase in the Ovx-A group (p<0.05). Histomorphometric measurements showed that the Shm group had normal trabecular structure, while the Ovx-PS group had a less well-formed trabecular structure with a loss in the trabecular number and thickness and a corresponding increase in the trabecular spacing (p<0.05). In the Ovx-A group, there was an improvement in the trabecular structure with an increase in the trabecular number and thickness and a loss in the trabecular space (p<0.05). Conclusion: Our study results suggest that alendronate sodium is a valuable treatment agent for osteoporosis in postmenopausal women.
