Öğe Diagnostic Value and Safety of Medical Thoracoscopy in the Management of Exudative Pleural Effusion(Wolters Kluwer Medknow Publications, 2016) Ozgul, Mehmet Akif; Cetinkaya, Erdogan; Tanriverdi, Elif; Cotuk, Mustafa; Acat, Murat; Gul, Sule; Seyhan, Ekrem CengizObjective: Medical thoracoscopy is a minimally invasive procedure that is performed by experienced pulmonologists under local anesthesia and conscious intravenous sedation. It allows direct observation and evaluation of the pleural space. Our aim is to evaluate the diagnostic efficacy and safety of this procedure while presenting our results of medical thoracoscopy performed by rigid thoracoscopy in our clinic. Methods: Thirty-seven patients who had gone thorough medical thoracoscopy between March 2011 and August 2014 were evaluated retrospectively. Results: Of these 37 patients, 26 were male and the average age was 50.94 +/- 15.38 years. Fourteen patients had right-sided pleural effusion, whereas 23 had left-sided pleural effusion. Closed pleural biopsy was performed previously in 16 patients with no diagnostic results. In 36 patients (97.3%), a specific diagnosis was achieved. One patient, diagnosed as lymphocytic pleuritis by medical thoracoscopy, underwent decortication and the pathology was consistent with biphasic malignant pleural mesothelioma. Another patient, diagnosed as chronic nonspecific pleuritis with medical thoracoscopy, underwent decortication and the diagnosis was fibrinous pleuritis characterized by extensive fibrosis. Three patients had expansion defects during the post-operative period. Hemothorax occurred in one patient that died of respiratory failure on day 34 of hospitalization. The median length of stay in the hospital after the procedure was 5 days (1-34). Conclusion: Medical thoracoscopy is a secure procedure with high diagnostic value in the management of exudative pleural effusion.Öğe Efficacy and safety of endobronchial ultrasound-guided transbronchial needle aspiration through the pulmonary arteries for the diagnosis of left hilar lesions(Turkish Assoc Tuberculosis & Thorax, 2018) Cetinkaya, Erdogan; Cortuk, Mustafa; Turan, Demet; Tanriverdi, Elif; Acat, Murat; Ozgul, Mehmet AkifIntroduction: Endobronchial ultrasonography (EBUS) is an endoscopic method that aids needle aspiration to see the bronchial wall and adjacent tissues with an ultrasound probe. Pulmonary arteries are rarely present between the bronchus wall and the tissue. In this case, it was necessary to make a selection between invasive processes and transbronchial needle aspiration (TBNA) through the pulmonary artery. There are few case reports about the safety of TBNA through the pulmonary artery. We aimed to present the results of EBUS guided TBNA through the pulmonary arteries. Materials and Methods: The data on four cases (three men) in whom EBUS guided TBNA was performed through the pulmonary artery between August 2010 and December 2015 were reviewed retrospectively. Procedures were conducted under local anesthesia and conscious sedation. For TBNA, 22-gauge needles were used. Cases were monitored for 24 hour after the procedures. Antibiotic prophylaxis and onsite cytopathology were not used. Results: All lesions existed were on the left hilar localization. Two of the diagnosed cases were carcinoma and one was the granulomatous lymphadenitis. We were not able to diagnose the last case. No complication was observed in any cases during the procedure. Conclusion: EBUS guided TBNA through the pulmonary arteries at left hilar lesions is safe. The rate of diagnoses from the tissues obtained is high. No special preparation is needed for the cases have no the pulmonary hypertension.Öğe Evaluation of Serum Biomarkers in Patients with Sarcoidosis: Can Visfatin Be a New Biomarker for Sarcoidosis?(Aves, 2020) Tanriverdi, Elif; Iliaz, Sinem; Cortuk, Mustafa; Turan, Demet; Chousein, Efsun Gonca Ugur; Gul, Sule; Ozgul, Mehmet AkifOBJECTIVES: Sarcoidosis is a chronic systemic inflammatory disease that affects multiple organ systems. The role of biomarkers in the diagnosis and prognosis of sarcoidosis is increasing. Interest in the role of adipose tissue-mediated inflammation in the pathogenesis of inflammatory diseases has increased in recent years. Visfatin is a proinflammatory adipocytokine that has been studied for several inflammatory diseases such as diabetes mellitus, obesity, and metabolic syndrome. We aimed to assess serum visfatin levels in sarcoidosis and its relationship with other markers of inflammation such as C-reactive protein (CRP), angiotensin-converting enzyme (ACE) and erythrocyte sedimentation rate (ESR). MATERIALS AND METHODS: We enrolled 59 patients with sarcoidosis and 21 healthy controls and measured plasma levels of visfatin, along with serum CRP, ESR, and ACE using ELISA (enzyme-linked immunosorbent assay) kits (Blue Gene Biotech, Shanghai, China). RESULTS: Visfatin levels did not differ significantly between the patients and control subjects (29.9 +/- 15.8 ng/mL for patients and 23.93 +/- 16.73 ng/mL for controls, p=0.15), and there was no correlation between visfatin and serum CRP, ACE, or ESR in patients with sarcoidosis. CONCLUSION: Visfatin is recently being discussed as a biomarker for inflammatory diseases in several studies, and results are controversial. In our study, no differences were found in the serum levels of visfatin between patients with sarcoidosis and the control group.Öğe General features of patients with Pulmonary Langerhans Cell Histiocytosis followed in our instution(Turkish Assoc Tuberculosis & Thorax, 2018) Acat, Murat; Tanriverdi, Elif; Ugur Chousein, Efsun Gonca; Demirkol, Baris; Yildirim, Binnaz Zeynep; Turan, Demet; Ozgul, Mehmet AkifIntroduction: Pulmonary Langerhans Cell Histiocytosis (PLCH) is a rare disease affecting young smokers. It is more common between the ages of 20-40 and equals the male/female ratio. Lung biopsy is the most useful methods for diagnosis. The first treatment is to quit smoking. Corticosteroids or chemotherapeutic agents can be used in severe progressive cases despite of quiting smoking. The patients with PLCH followed in our clinic were assessed with general clinical features in the light of the literature. Materials and Methods: We retrospectively evaluated patients with PLCH in our clinic between January 1999 and June 2017. Results: The female and male distribution of the 21 patients was 11/10. The average age was 35.04 +/- 11.78 years. All patients were active smokers at the time of admission. The most common symptom was dyspnea. The most common finding in the pulmonary function tests was obstructive ventilatory defect. The DLCO value of the 70% patient in the carbonmonooxid diffusion test was below 80%. The most common pathologic findings detected in high-resolution chest tomography (HRCT) were cystic lesions involving bilateral upper and middle areas. There were 3 (14%) patients with pneumothorax at the time of admission and 6 (28.5%) patients with pneumothorax history before. The most common diagnostic method was open lung biopsy. All the patients quit cigarette after the diagnosis. There were 6 patients using steroid therapy, 1 patient receiving steroid and bosentan therapy, and 1 patient made pleurectomy due to recurrent pneumothorax. Lung transplantation was done to patient who received combined bosentan treatment with steroids. Conclusion: PLCH is a rare disease and should be considered in young, smokers with spontaneous pneumothorax and cystic lung disease in the differential diagnosis. As more diffusions are affected in patients, respiratory functions for follow-up should be evaluated with diffusion tests. It is essential to quit smoking in therapy.Öğe Oki stent application in different indications: Six cases(Wiley, 2018) Ozgul, Mehmet Akif; Cetinkaya, Erdogan; Cortuk, Mustafa; Tanriverdi, Elif; Yildirim, Binnaz Zeynep; Balci, Merih Kalamanoglu; Issaka, AdamuIntroductionWe have used Oki stents for a number of different indications. After discovering that there are limited reports in the literature on these stents, we were motivated to share our experiences in Oki stenting. ObjectivesWhile there is vast knowledge on double Y-stents, the Oki stent is a relatively recent development in pulmonology. Here, we demonstrate that stenting of the right secondary carina using an Oki stent should be considered for obstructions in this region. MethodsWe placed 13 mm x 10 mm x 9 mm Oki stents in six patients under general anesthesia via rigid bronchoscopy. ResultsThree cases were post-transplant patients with malacia, stenosis, and bronchopleural fistula. One case had an airway obstruction due to malignant disease, another case had a right aortic arc and aberrant left subclavian artery anomaly, and the final case had bronchopleural fistula. No serious complications were observed during stent placement. ConclusionsOki stents can safely be used for many clinical conditions. Patients benefit greatly from stenting; however, two of our cases died due to infection, and one case died due to malignancy.Öğe A rare tumor of trachea: Inflammatory myofibroblastic tumor diagnosis and endoscopic treatment(Elsevier, 2014) Ozgul, Mehmet Akif; Toru, Umran; Acat, Murat; Ozgul, Guler; Cetinkaya, Erdogan; Dincer, H. Erhan; Omaygenc, Derya OzdenInflammatory myofibroblastic tumors (IMTs) are rare childhood neoplasms, with benign clinical course. Although etiology of IMTs are not clear, recent studies have reported that IMT is a true neoplasm rather than a reactive or inflammatory lesion. IMTs are rarely seen in adults and tracheal involvement is also rare both in adults and also in children. We describe a 16-year old female patient who was misdiagnosed and treated as asthma in another center for a few months and presented with acute respiratory distress due to upper airway obstruction. Computerized tomography (CT) of the chest and rigid bronchoscopy revealed a mass lesion that was nearly totally obliterating tracheal lumen. Bronchoscopic resection was performed under general anesthesia and the final pathological diagnosis was tracheal IMT. (C) 2014 The Authors.

Erhan; Omaygenc, Derya Ozden[No abstract available]Öğe Tracheobronchial Amyloidosis Mimicking Tracheal Tumor(Hindawi Ltd, 2016) Tanriverdi, Elif; Ozgul, Mehmet Akif; Uzun, Oguz; Gul, Sule; Cortuk, Mustafa; Yasar, Zehra; Acat, MuratTracheobronchial amyloidosis is a rare presentation and accounts for about 1% of benign tumors in this area. The diagnosis of disease is delayed due to nonspecific pulmonary symptoms. Therapeutic approaches are required to control progressive pulmonary symptoms for most of the patients. Herein, we report a case of a 68-year-old man admitted with progressive dyspnea to our institution for further evaluation and management. He was initially diagnosed with and underwent management for bronchial asthma for two years but had persistent symptoms despite optimal medical therapy. Pulmonary computed tomography scan revealed severe endotracheal stenosis. Bronchoscopy was performed and showed endotracheal mass obstructing 70% of the distal trachea and mimicking a neoplastic lesion. The mass was successfully resected by mechanical resection, argon plasma coagulation (APC), and Nd-YAG laser during rigid bronchoscopy. Biopsy materials showed deposits of amorphous material by hematoxylin and eosin staining and these deposits were selectively stained with Congo Red. Although this is a rare clinical condition, this case indicated that carrying out a bronchoscopy in any patient complaining of atypical bronchial symptoms or with uncontrolled asthma is very important.
