    Sarcoidosis is an idiopathic granulomatous disease. It usually affects the lung. The diagnosis may be problematic since the known causes of granulomatous inflammation must be excluded. This multicenter study aimed to evaluate the clinical presentations and diagnostic approaches of sarcoidosis. The study protocol was sent via internet, and the participants were asked to send the information (clinical, radiological and diagnostic) on newly diagnosed sarcoidosis cases. 293 patients were enrolled within two years. Pulmonary symptoms were found in 73.3% of the patients, and cough was the most common one (53.2%), followed by dyspnea (40.3%). Constitutional symptoms were occured in half of the patients. The most common one was fatigue (38.6%). The most common physical sign was eritema nodosum (17.1%). The most common chest radiograhical sign was bilateral hilar lymphadenomegaly (78.8%). Staging according to chest X-ray has revealed that most of the patients were in Stage I and Stage II (51.9% and 31.7%, respectively). Sarcoidosis was confirmed histopathologically in 265 (90.4%) patients. Although one-third of the bronchoscopy was revealed normal, mucosal hyperemi (19.8%) and external compression of the bronchial wall (16.8%) were common abnormal findings. The 100% success rate was obtained in mediastinoscopy among the frequently used sampling methods. Transbronchial biopsy was the most frequently used method with 48.8% success rate. Considering sarcoidosis with its most common and also rare findings in the differential diagnosis, organizing the related procedures according to the possibly effected areas, and the expertise of the team would favor multimodality diagnosis.

    (Galenos Publishing House, 2013) Özlu T.; Bülbül Y.; Taşbakan S.; Kiliç H.; Kuyucu T.; Yildiz T.; Özdemir T.; Duru S.; Öztuna F.; Adigüzel N.; Saǧlam L.; Coşkun A.S.; Örnek T.; Gündüz G.; Filiz A.; Özdemir L.; Okumuş G.
    Objective: Unlike seasonal influenza, seen in previous years, the strain identified in the 2009 influenza-A pandemic involved high mortality. In this study, prognostic factors and general characteristics of pneumonia cases developed in Turkey during the H1N1 pandemic between October 2009 and January 2010 were analyzed. Study Design: Multicenter retrospective study. Material and Methods: This multicentric retrospective study was conducted between August and October 2010 and patients' data were collected by means of standard forms. Results: The study included 264 pneumonia cases, collected from 14 different centers. Mean age was 47.5±18.6 years. Nineteen patients (7.2%) were pregnant or had a new birth and comorbid diseases were detected in 52.3% of all patients. On admission, 35 (13.8%) cases had altered mental status. Overall, 32.6% were treated in intensive care units (ICU) and invasive/non-invasive mechanical ventilation was performed in 29.7%. The mean duration of ICU stay was 2.9±6.2 and total hospital stay was 12.0±9.4 days. Mortality rate was 16.8% (43-cases). The length of ICU treatment, total hospital stay, and mortality were significantly higher in H1N1-confirmed patients. Mortality was significantly higher in patients with dyspnea, cyanosis, and those who had altered mental status on admission. Patients who died had significantly higher rate of peripheral blood neutrophils, lower platelet counts, higher BUN, and lower SaO2 levels. Conclusion: This study showed that pneumonia developed during H1N1 pandemic in our country had resulted in a high mortality. Mortality was especially high among patients with cyanosis, altered mental state and those with lower SaO2. © Trakya University Faculty of Medicine.

    Asthma-chronic obstructive pulmonary disease overlap: Results from a national-multicenter study; [Astım KOAH overlap: Ulusal çok merkezli bir çalışma sonuçları]
    (Ankara University, 2024) Çelik G.E.; Aydin Ö.; Şen E.; Demir T.; Gemicioğlu B.; Kiyan E.; Mungan D.; Kivilcim Oğuzülgen İ.; Polatli M.; Göksel Ö.; Sayiner A.; Yildirim N.; Yildiz F.; Yorgancioğlu A.; Elhan A.H.; Yildiz Ö.; Başyiğit İ.; Börekçi Ş.; Havlucu Y.; Okumuş G.; Türk M.; Saryal S.
    Introduction: Patients with asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO) have a greater disease burden than those with COPD or asthma alone. In this study, it was aimed to determine the prevalence, risk factors, and clinical features of ACO because there are limited national data in Türkiye. Materials and Methods: The study was conducted in a cross-sectional design in nine tertiary-care hospitals. The patients followed with a diagnosis of asthma or COPD for at least one year were enrolled in the study. The frequency of ACO and the characteristics of the patients were evaluated in the asthma and COPD groups. Results: The study included 408 subjects (F/M= 205/203, mean age= 56.24 ± 11.85 years). The overall prevalence of ACO in both groups was 20.8% (n= 85). The frequency was higher in the COPD group than in the asthma group (n= 55; 33.3% vs. n= 22; 9.8%), respectively (p= 0.001). Patients with ACO had similarities to patients with COPD in terms of advanced age, sex, smoking, exposure to biomass during childhood, being born in rural areas, and radio-logic features. Characteristics such as a history of childhood asthma and allergic rhinitis, presence of chronic sinusitis, NSAID hypersensitivity, atopy, and high eosinophil counts were similar to those of patients with asthma (p< 0.001). The annual decline in FEV1 was more prominent in the ACO group (mean=-250 mL) than in the asthma (mean change=-60 mL) and COPD (mean change=-230 mL) groups (p= 0.003). Conclusion: This study showed that ACO was common among patients with asthma and COPD in tertiary care clinics in our country. ACO should be considered in patients with asthma and COPD who exhibit the abovementioned symptoms. © 2024 by Tuberculosis and Thorax.
