Multivariable logistic regression analysis showed age ≥75 years (OR=1.83;CI 1.09-3.09; p=0.023), female gender (OR=2.70;CI 1.6-4.50; p less then 0.001), and psychoactive drug use (OR=2.14;CI 1.32-3.48; p=0.002) as independent predictors of falls. Conclusion We found that about one-third of geriatric outpatients were on psychoactive drug treatment in Turkey that was independently associated with the risk of falls.Objective Vena cava superior syndrome comprises various symptoms of compression of vena cava superior. The results of increased venous pressure in the upper body may cause edema of the head and neck associated with cyanosis, plethora and distended subcutaneous vessels. Vena cava superior syndrome is rare in childhood. Therefore, we planned this retrospective study. Methods The retrospective study was carried out on the children with mediastinal tumors in the Department of Pediatric Hematology-oncology, Erciyes University Faculty of Medicine, Kayseri, Turkey , from January 2010 to December 2017. Diagnostic procedures included hematological investigations, chestradiography, thoracic computed tomography, echocardiography and lymph node or mediastinal biopsy. Results In this study, 19 (five were female) of 41 patients with mediastinal tumors had Vena cava superior syndrome. Diagnosis included Hodgkin's lymphoma in seven (37%), non-Hodgkin's lymphoma in six (32%), acute T- lymphoblastic leukemia in four (21%), neuroblastoma and anaplastic round cell sarcoma in one each respectively. All of the 19 patients' facial swelling, venous distention and mediastinal widening. All patients received intravenous corticosteroids (0.6 mg/kg dexamethasone). Furthermore, the patient with anaplastic round cell sarcoma received emergency radiotherapy. No patients died because of Vena cava superior syndrome. Conclusion Vena cava superior syndrome is a medical emergency that requiresurgent tre
