Magnesium (Mg) deficiency may affect bone metabolism by increasing osteoclasts, decreasing osteoblasts, promoting inflammation/oxidative stress, and result in subsequent bone loss. The objective of the present study was to identify the molecular mechanism underlying the bone protective effect of different forms of Mg (inorganic magnesium oxide (MgO) versus organic magnesium picolinate (MgPic) compound) in rats fed with a high-fat diet (HFD). Forty-two Wistar albino male rats were divided into six group (n = 7): (i) control, (ii) MgO, (iii) MgPic, (iv) HFD, (v) HFD + MgO, and (vi) HFD + MgPic. Bone mineral density (BMD) increased in the Mg supplemented groups, especially MgPic, as compared with the HFD group (p &lt, 0.001). As compared with the HFD + MgO group, the HFD + MgPic group had higher bone P (p &lt, 0.05) and Mg levels (p &lt, 0.001). In addition, as compared to MgO, MgPic improved bone formation by increasing the levels of osteogenetic proteins (COL1A1 (p &lt, 0.001), BMP2 (p &lt, 0.001), Runx2 (p &lt, 0.001), OPG (p &lt, 0.05), and OCN (p &lt, 0.001), IGF-1 (p &lt, 0.001)), while prevented bone resorption by reducing the levels of RANK and RANKL (p &lt, 0.001). In conclusion, the present data showed that the MgPic could increase osteogenic protein levels in bone more effectively than MgO, prevent bone loss, and contribute to bone formation in HFD rats.

In this study, we aimed to compare osteoporosis (OP)-related bone mineral density, and bone turnover (markers of formation, and resorption) between patients with Fibromyalgia Syndrome (FMS) and degenerative disc disease, and to determine the relationship of these parameters with clinical, functional and emotional evaluation outcomes in FMS. Fifty premenopausal women with FMS and 50 premenopausal female control patients with degenerative disc disease were enrolled. The patient and physicians global assessment of disease were assessed on a visual analog scale (VAS). Disease severity was determined with the Fibromyalgia Impact Questionnaire (FIQ). For the evaluation of fatigue The Modified Fatigue Impact Scale (MFIS) and Fatigue Severity Scale (FSS) were used. The quality of life of all patients was evaluated using Nottingham Health Profile (NHP), Oswestry Disability Index (ODI), and QUALEFFO-41. The emotional state of all patients with chronic pain was evaluated with Hospital Anxiety and Depression Scale (HADS). Bone turnover markers [serum bone-specific alkaline phosphatase (bALP) and serum osteocalcin as markers of bone formation, serum â-isomerized Carboxy-terminal telopeptide of collagen type I (â-CTX) and urine hydroxyproline (OH-Pro) as markers of bone resorption], serum parathyroid hormone (PTH) and 25-hydroxyvitamin D [25(OH)D] levels, lumbar spine and left proximal femur bone mineral density (BMD) and T scores were measured in both groups. The FIQ, MFIS, FSS, NHP, ODI, QUALEFFO-41, HADS-A and HADS-D scores were statistically significantly higher in the FMS group relative to the patient control group. A significant difference between FMS and patient control group as for bone formation (bALP and osteocalcin) and resorption (â-CTX ve OH-Pro) markers was not detected. In the FMS group lumbar spine and left proximal femur BMD and T score values were significantly lower when compared with the patient control group. In the FMS group significant correlations were found between serum 25(OH)D and â-CTX values and VAS scores evaluated by the patient and physician, SS scale, FIQ, MFIS, ODI, QUALEFFO-41 and NHP scores. In conclusion many factors including depression and anxiety attacks, the presence of widespread pain and a decline in physical activity level and quality of life in FMS patients make them more prone to osteoporosis. In patients with FMS, osteoporosis is a major cause of morbidity and should not be neglected. [Med-Science 2018; 7(1.000): 9-16]

14th Congress of the Balkan-Cities-Association-of-Nephroogy-Dialysis-Transplantation-and-Artificial-Organs -- SEP 20-23, 2018 -- Budva, MONTENEGRO WOS:000547335800002 Objective: We compared the glomerular filtration rate (GFR) values as measured by the gamma camera and eGFR methods, calculated by the Modification of Diet in Renal Disease (MDRD) and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula in patients who underwent diethylenetriamine penta-acetic acid (DTPA) dynamic renal scintigraphy for suspected obstructive uropathy. Materials and Methods: A total of 59 patients were included in this retrospective study. On the basis of the eGFR results, patients were divided into three groups; eGFR >90 mL min-1 (Group 1), 60-90 mL min-1 (Group 2), and

Aim: Thyroidal incidentalomas (Tis) detected by F-18 fluorodeoxyglucose positron emission tomography/computed tomography (F-18FDG PET/CT) may be associated with three different causes that include metastasis of another malignancy, primary thyroid gland malignancies and lastly benign thyroidal nodules, all require different clinical approaches. For appropriate treatment, quick characterization of the Ti is important, preferably with a lesser invasive method. Our aim was to determine whether the characterization of TIs can be performed with FDG-PET/CT, due to contribute faster diagnosis, and initiation of the therapy.Material and Methods: Forty-four patients with detected TIs in FDG-PET/CT were included in the study. The relationship between metabolically/morphological parameters and pathology results were evaluated statistically. If two subsequent cytology were negative, nodule accepted as benign. If cytology result was suspected or malignant, histopathological confirmation was made. For these patients, histopathological results were accepted as definite diagnosis. Results: Malignant thyroidal pathologies were detected in 29.5% of patients. We could not find any significant relationship between age, nodule size and SUVmax value and pathology results. According to ROC analysis, there were not any cut-off value for nodule size and SUVmax. Similar results were also obtained for papillary carcinoma as a special subgroup.Conclusion: Characterisation of TIs could not be performed by using age, nodule size and SUVmax. Therefore, TIs which detected by FDG-PET/CT should be examined pathologically due to high risk of malignancy.Keywords: Thyroidal incidentalomas; FDG-PET/CT; malignant; characterization.

Langerhans cell histiocytosis (LCH) is a benign disorder related to the histiocytes which can infiltrate bone tissue. The most effective method for demonstrating severity of this disease is PET/CT and bone scintigraphy might show bone lesions. We present a seventeen year old male patient with disseminated LCH presented with exophtalmos and having multiple vertebral lesions which were identified by F-18 FDG PET/CT scan and diagnostic CT but not in the bone scintigraphy.Langerhans hücreli histiositoz (LHH) histiyositlerle ilişkili kemiği infiltre edebilen iyi huylu bir hastalıktır. Bu hastalığın yaygınlığını gösteren en etkili metod PET/BT’dir ve kemik sintigrafisi de kemik lezyonlarını gösterir. Yaygın LHH tanısı ve egzoftalmus ile takip edilen, çoklu vertebral lezyonları F-18 FDG PET/BT ve tanısal BT tetkikleri ile saptanan ancak kemik sintigrafisinde tespit edilemeyen, on yedi yaşında erkek hastayı sunmaktayız.

Objective: Pulmonary thromboembolism (PTE) named due to migration of clots formed in systemic venous system to pulmonary vascular bed is a serious clinical table. After acute DVT, asymptomatic PTE is seen about 40-60% and this situation can not be discovered because of silent clinical course. In this study, we aimed to compare sensivity and spesifity of multi detector computerized tomography (MDCT), which is used extensively in recent years, with ventilation-perfusion (V/P) scintigraphy which is used formerly for diagnosis of asymptomatic PTE developed after acute lower extremity DVT. Methods: The study was carried out 25 patients who were admitted to our clinic and treated for lower extremity acute DVT. Pregnants, and cases with recurrent DVT, presence of symptomatic PTE during admission, thrombosis extending to vena cava, and history of passed PTE were excluded from the study. DVTs in patients were diagnosed by color doppler, and confirmed by D-dimer test. After patients\'s admission, V/P scintigraphy and MDCT were used to detects asymptomatic PTE at 1st and 8 th day of the admission. Results: D-dimer was measured as higher in 24 of 25 patients with asemptomatic PTE. Ten patients were diagnosed by MDCT. Development of asymptomatic PTE related to acute DVT was determined as 40%. Conclusion: In terms of diagnostic value, MDCT was found more useful than V/P scintigraphy., Amaç: Pulmoner tromboemboli (PTE) sistemik venöz sistemde oluşan pıhtıların pulmoner vasküler yatağa göçü ile ortaya çıkan klinik tabloya verilen isimdir. Akut derin ven trombozu (DVT) sonrası ortalama %40-60 oranında asemptomatik PTE görülmekte ve bu durum sessiz klinik seyir nedeniyle fark edilmemektedir. Bu çalışmamızda akut alt ekstremite DVT\'sine bağlı gelişen asemptomatik PTE tanısında hala günümüzde önemli bir yer tutan ventilasyon-perfüzyon (V/P) sintigrafisi ile son yıllarda kullanılmaya başlanan multi-detektor bilgisayarlı tomografinin (MDBT) sensitivite ve spesifitesini karşılaştırmayı amaçladık. Yöntemler: Çalışma alt ekstremite akut DVT nedeniyle kliniğimize yatırılarak tedavisi planlanan 25 hastada gerçekleştirildi. Gebeler, nüks DVT vakaları, müracaat esnasında semptomatik PTE tablosu olanlar, vena kavaya uzanım gösteren trombüsü olanlar, önceden geçirilmiş PTE öyküsü olanlar çalışmaya dahil edilmedi. Hastalarda DVT tanısı renkli doppler USG ile konulup, D-dimer testiyle teyit edildi. Hastalara yatışının 1.ve 8. günlerinde V/P sintigrafisi ve MDBT yapılarak asemptomatik PTE varlığı araştırıldı. Bulgular: Pulmoner tromboemboli açısından asemptomatik olan 25 DVT hastasının 24\'ünde D-dimer normalin üstünde ölçüldü. MDBT ile 10 hastaya PTE tanısı konuldu. Akut DVT\'ye bağlı %40 oranında asemptomatik PTE geliştiği tespit edildi. Sonuç: Multi-detektor bilgisayarlı tomografi tanı değeri açısından V/P sintigrafisinden daha faydalı bulundu.

Aim: The bone scintigraphy is indicated in patients with costochondral pain in order to identify the organic etiology. We aimed to investigate the local and projecting pain, or incidental findings in the three phase bone scintigraphy of the patients referred for costochondral pain. Methods: We included 50 patients (36F, 24M; mean: 41±18 years-old) referred to our department for three phase bone scintigraphy for costochondral pain between January 2009-July 2012. Results: Among the 50 patients 22 had normal scintigraphy. An increased activity accumulation in the sternoclavicular joint was observed in 12 patients (right in 4, left in 4 and bilateral in 4) only in late phase and in 9 patients (right in 2, left in 1 and bilateral in 6) with increased vascularity. Among projecting pain causes, activity was present on sternum in 4 patients, on humerus in 2 patients and on the first costae in 2 patients. For the characterization of inflammatory pathology, the three phase bone scintigraphy showed sensitivity, specificity, accuracy, positive and negative predictive values of 43%, 94%, 78%, 77% and 78% respectively. Conclusion: Bone scintigraphy is an effective diagnostic method for the identification of local or projecting pain, and additionally unexpected incidental pathologies ssociated with costochondral pain. However regarding the characterization of inflammatory process false negatives should be considered. Conflict of interest:None declared.

Unilateral pulmonary artery agenesis without any cardiovascular malformation is a rare anomaly. We present the imaging findings of a patient who was diagnosed as isolated left pulmonary artery agenesis. A 27-year-old female patient was admitted to our hospital due to dyspnea during exercise for five years. Chest X-ray revealed minimally small left pulmonary hilum and left lung. She was admitted to our clinic with the suspicion of pulmonary artery pathology. Absent perfusion of the left lung with normal ventilation was visualized on scintigraphy. MDCT angiography of pulmonary arteries showed absent left main pulmonary artery with systemic collaterals around left hemithorax. Pulmonary artery agenesis can be asymptomatic and isolated until adulthood. Both scintigraphy and CT angiography images of pulmonary artery agenesis of a patient are rare in the literature. Pulmonary ventilation-perfusion scintigraphy can be used not only for pulmonary embolism but also pathologies involving pulmonary artery and its branches. Conflict of interest:None declared.

Aim: Diagnosis of the hepatic hemangiomas is sometimes difficult by means of computed tomography (CT) or ultrasound (USG). This kind of lesions can be accurately identified by Tc-99m labeled erythrocyte -red blood cell (RBC) imaging. However there are controversial results about small lesions (

UNLABELLED We present a 20 year-old male patient who had prominent positional proptosis of the right eye and admitted to the hospital for tonsillectomy operation. After conventional ophthalmological examination, magnetic resonance imaging (MRI) and Tc 99m labeled erythrocyte scintigraphy were performed to confirm the diagnosis. Although it is rare to perform scintigraphy for this pathology, the visualization of intraorbital hemangioma was very obvious and we would like to present the visualization of the intraorbital hemangioma both with scintigraphy and MRI. CONFLICT OF INTEREST None declared.

Haemophagocytic lymphohistiocytosis (HLH) is a rare immune disorder that predominantly affects macrophages and T lymphocytes and leads to multiple organ disease and death. The characteristic pathological finding in the bone marrow and the other affected tissues is haemophagocytosis of macrophages (macrophages digesting erythrocyte). Primary (hereditary) and secondary (acquired) forms of the disease are present. A patient with documented HLH disease revealed by positron emission tomography/CT is reported in this paper.
