Publication Metadata only Parenchymal density changes in acute pulmonary embolism: Can quantitative CT be a diagnostic tool? A preliminary study(ELSEVIER SCIENCE INC, 2017) ÇİMŞİT, NURİ ÇAGATAY; Duman, Ikram Eda; Cimsit, Canan; Yildizeli, Sehnaz Olgun; Cimsit, Nuri CagatayPurpose: Determine the ability of quantitative CT (QCT) in defining parenchymal density changes in acute pulmonary embolism (PE). Material & methods: Mean lung density (MLD) and percentage distribution values (PDV) were calculated in 34 patients suspected of PE using software application based on computerized volumetric anatomical segmentation. Results: Total, left, and right MLD differed significantly between emboli positive(n = 23) and negative(n = 11) groups(p < 0.006, p < 0.009, p < 0.014). PDVs differed between groups (p < 0.05) except for LUZ and RLZ. When PE was present in lobe &/segment branches, PDVs were significantly lower except RUZ. Conclusion: QCT is a promising application for defining parenchymal density changes in PE revealing potential functional impact of emboli. This preliminary study suggests QCT could provide added value to CTPA in peripheral PE. (C) 2016 Elsevier Inc.

Materials and methods: Twenty-five patients underwent bronchial artery embolization, using coaxial microcatheter technique, with a liquid agent, n-butyl-2-cyanoacrylate (NBCA), named glue, for life-threatening hemoptysis. The technical and clinical outcomes were followed in terms of immediate control of bleeding, recurrence of hemoptysis and complications of the procedure. Results: Four patients had acute hemoptysis when they were evaluated. The average number of arteries embolized per patient was 2.9. BAEs were successful in controlling hemoptysis immediately in all 25 patients (100%) and in 24 patients (96%) at 1 month follow-ups. One patient had recurrent hemoptysis on the tenth day after embolization. The follow-up time ranged from 2 to 63 months (mean 14 months). Six patients (25%) died all as a result of their disease process. Bleeding recurred in 3 patients after 30 days (7th, 11th, 12th months). One patient had vomitting attacks with dysphagia after the procedure that lasted 24 h. Three patients had transient thoracic pain lasting 3-5 days. There were no procedure related spinal or vascular complications. Conclusions: Glue embolization with microcatheter technique is a safe and effective treatment in cases of life-threatening hemoptysis with a very high rate of success and low rate of complications.

Cagatay; Ayranci, Gulcicek; Richardson, Malcolm; Korten, VolkanInvasive fungal infections (lFl) are on the rise due to increasing numbers of immunosuppressed and critically ill patients. A malignant-looking pulmonary nodule in an immunosuppressed patient may indeed be caused by a fungal organism. We report a patient, who was eventually diagnosed with an IFI caused by an agent of hyalohyphomycosis, Talaromyces sp determined via molecular methods and succesfully treated with voriconazole.

Ç. , GÜLLÜOĞLU M. B. , Ahiskali R. A. , Akalin N. S. , ARIBAL M. E.Background. Fine needle aspiration biopsy (FNAB) is an important tool in the diagnosis of thyroid nodules. Aim. Our aim was to investigate the malignancy criteria in thyroid nodules by gray-scale ultrasonography (US) and duplex Doppler ultrasonography (DDUS), and their usefulness in reducing the number of unnecessary FNAB’s. Study design. This was a prospective observational study. Subjects and methods. 181 benign and 18 malignant thyroid nodules were evaluated by US and DDUS before FNAB or thyroidectomy. US was used to note size, shape, internal structure, nodule echogenicity, marginal properties, peripheral hypoechogenic halo, and microcalcifications. DDUS studies were used to evaluate the maximum and minimum flow velocity (Vmax and Vmin), systolic/diastolic flow velocity ratio (S/D), pulsatility index (PI), resistive index (RI), acceleration time (AT) and acceleration value. Results. Contour irregularity, size and presence of microcalcifications (p<0.001, p=0.02 and p=0.002, respectively) and S/D, Vmin, PI, RI and AT were significantly different (p=0.004, p=0.007, p=0.032, p=0.003 and p=0.003, respectively) were significant for malignant nodules. Benign and malignant nodules with or without suspicious US findings had similar DDUS findings. Vmax, Vmin, PI, RI, and AT were significantly different in the presence of microcalcification (p=0.043, p=0.001, p=0.031, p=0.04, and p=0.019 respectively). AT was significantly different in the case of absence of microcalcification (p=0.019). Comparing the irregular margins, Vmin, PI and RI were significantly different (p=0.014, p=0.003, and p=0.014 respectively). Conclusion. Benign and malignant thyroid nodules can be differentiated using gray-scale US findings and DDUS based indices together to reduce the number of unnecessary FNAB’s.Publication Metadata only Esophageal perforation: A rare but fatal complication of urgent sengstaken blakemore tube intubation [Özofagus perforasyonu: Acil sengstaken blakemore tüp kullani{dotless}mi{dotless} sonrasi{dotless} gelişen nadir fakat ölümcül komplikasyon](Turkish Society of Medical and Surgical Intensive Care Medicine, 2014) BİLGİN, HÜSEYİN; Akbaş T., Bilgin H., Yeǧin E.G., Çimşit N.C., Özdoǧan O.C., Karakurt S.Acute variceal bleeding is an important cause of mortality among cirrhotic patients. Endoscopic band ligation and medical vasoactive drugs are the main treatment options for actively bleeding varices. In some cases, these therapies can fail and a Sen-gstaken Blakemore tube (SBT) is used to stop the bleeding by direct compression of varices. Although it is very effective in stopping variceal bleeding, SBT has some lethal complications. In this paper, we discuss the case of a patient who developed esopha-geal perforation after insertion of the SBT.Publication Metadata only Diffusion-weighted MR imaging in postoperative follow-up: Reliability for detection of recurrent cholesteatoma(ELSEVIER IRELAND LTD, 2010) ÇİMŞİT, NURİ ÇAGATAY; Cimsit, Nuri Cagatay; Cimsit, Canan; Baysal, Begumhan; Ruhi, Ilteris Cagatay; Ozbilgen, Suha; Aksoy, Elif AyanogluIntroduction: Cholesteatoma is a progressively growing process that destroy the neighboring bony structures and treatment is surgical removal. Follow-up is important in the postoperative period, since further surgery is necessary if recurrence is present, but not if granulation tissue is detected. This study evaluates if diffusion-weighted MR imaging alone can be a reliable alternative to CT, without use of contrast agent for follow-up of postoperative patients in detecting recurrent cholesteatoma. Materials and methods: 26 consecutive patients with mastoidectomy reporting for routine follow-up CT after mastoidectomy were included in the study, if there was loss of middle ear aeration on CT examination. MR images were evaluated for loss of aeration and signal intensity changes on diffusion-weighted sequences. Surgical results were compared with imaging findings. Results: Interpretation of MR images were parallel with the loss of aeration detected on CT for all 26 patients. Of the 26 patients examined, 14 were not evaluated as recurrent cholesteatoma and verified with surgery (NPV: 100%). Twelve patients were diagnosed as recurrent cholesteatoma and 11 were surgically diagnosed as recurrent cholesteatoma (PPV: 91.7%). Four of these 11 patients had loss of aeration size greater than the high signal intensity area on DWI, which were surgically confirmed as granulation tissue or fibrosis accompanying recurrent cholesteatoma. Conclusion: Diffusion-weighted MR for suspected recurrent cholesteatoma is a valuable tool to cut costs and prevent unnecessary second-look surgeries. It has the potential to become the MR sequence of choice to differentiate recurrent cholesteatoma from other causes of loss of aeration in patients with mastoidectomy. (C) 2009 Elsevier Ireland Ltd.

Materials and methods: A total of 692 computed tomography pulmonary angiographies with PE were enrolled, and patients were grouped according to clot localization. Parenchymal findings, morphometric measurements of right heart function, and contrast reflux in IVC were noted. Results: Differences were found between groups for most measurements, and central PE was associated with significantly higher right ventricle (RV) and pulmonary artery diameters, ratio of RV diameter to left ventricle (LV) diameter (RV/LV) >= 1, and IVC reflux. Conclusions: Significant association was present among clot distribution in PE, morphometrics, IVC reflux, and pleuroparenchymal findings. (C) 2015 Elsevier Inc. All rights reserved.
