Introduction: Fusarium species cause severe infections in patients with hematologic malignancies. The types of infection caused by Fusarium spp. in humans range from infections of nail, skin, and eye in immunocompetent host to invasive and disseminated infections in mainly immunocompromised patients. Methods: We retrospectively indentified patients with hematologic malignancy and positive cultures for Fusarium species at the University Hospital (1995-2014). Results: Thirteen cases were identified over study period. Patient demographic and underlying risk factors for fusariosis are presented in Table I. Most patients had uncontrolled hematological malignancy. All patients were neutropenic at diagnosis. Pulmonary involvement was evident in 3/13 patients (23%). Skin lesions were present in 2/13 (15%) patients. Fusariosis presented as a breakthrough infection in 8/13 (62%) of patients (Table II). Positive blood cultures were in the 6/13 (46%). Conclusions: Our study has several limitations due to its retrospective nature and its relatively small size. Fusariosis, althought uncommon, continues to have poor prognosis in neutropenic leukemic patients who present with fungemia. The optimal therapy for fusariosis remains undefined, because of its rarity and the complex clinical scenarious in patients with severe immunosupression. Table 1.

Background: Type 2 diabetes mellitus (DM) has an increased fracture risk due to loss of bone quality and tendency to falling. The aim of the study was to analyze the incidence of osteoporosis and vertebral fractures (VF) in postmenopausal women with type 2 DM and to define the risk factors of VF in terms of clinical, metabolic characteristics and diabetes related microvascular complications.Methods: The 42 postmenopausal patients with type 2 DM were included to the study in Haseki Training and Research Hospital outpatient clinics.Results: Osteoporosis with regard to lumbar spine (LS) and femur neck (FN) was 8.4%, 19.4%, respectively. Vertebral fracture ratio was 31%. There was no statistical significance between vertebral fracture and osteoporosis. In logistic regression analysis, longer postmenopausal period, higher postprandial blood glucose (PBG), presence of peripheral neuropathy was found associated with vertebral fracture (p=0.04, 0.04, and 0.05, respectively).Conclusions: In this study we suggest to consider the length of postmenopausal period, PBG and peripheral neuropathy for assessing the risk of VF.
