    Objective: The purpose of this study was to summarize our clinical results with distraction osteogenesis for the treatment of infected tibial nonunion around the ankle joint. Methods: Between 1994 and 2009, 13 patients with a mean age of 50 years (range: 27-79 years) underwent tibial reconstruction for the treatment of infected nonunion of the distal tibia, with a mean bone loss of 4.8 cm (range: 1-7 cm). Lengthening over an intramedullary nail as a second procedure was used in 2 patients, bifocal compression and distraction technique in 5 cases, compression with Ilizarov external fixator in 5 cases, and Taylor Spatial Frame (TSF, Smith \& Nephew, Memphis, TN, USA) in 1 case. At final follow-up, functional and radiographic results were evaluated according to Paley's bone and functional healing criteria. Results: Mean duration of follow-up was 36 months. Mean external fixation time was 198 days, and mean external fixation index was 29 days/cm. According to Paley's bone healing criteria, there were 10 excellent, 2 good, and 1 poor result(s)

    A Comparative Olfactory MRI, DTI and fMRI Study of COVID-19 Related Anosmia and Post Viral Olfactory Dysfunction
    (ELSEVIER SCIENCE INC, 2022-01-01) Yildirim, Duzgun; Kandemirli, Sedat Giray; Sanli, Deniz Esin Tekcan; Akinci, Ozlem; Altundag, Aytug
    Rationale and Objective: To evaluate how COVID-19 anosmia imaging findings resembled and differed from postinfectious olfactory Material and Methods: A total of 31 patients presenting with persistent COVID-19 related OD and 97 patients with post-infectious OD were included. Olfactory bulb MRI, DTI and olfactory fMRI findings in both groups were retrospectively assessed. Results: All COVID-19 related OD cases were anosmic, 18.6\% of post-infectious OD patients were hyposmic and remaining 81.4\% were anosmic. Mean interval between onset of OD and imaging was 1.5 months for COVID-19 related OD and 6 months for post-infectious OD. Olfactory bulb volumes were significantly higher in COVID-19 related OD than post-infectious OD. Deformed bulb morphology and increased olfactory bulb signal intensity was seen in 58.1\% and 51.6\% with COVID-19 related OD
