Objective To investigate the factors affecting compliance with positive airway pressure (PAP) therapy and establish the relationship between compliance and pulmonary function tests (PFT) in patients with OSA. Material and methods In this prospective study, patients with OSA using PAP devices were questioned about the complaints related to the device. Depression and anxiety scales along with PFT parameters were also assessed. Results Of 98 participants, 63% were men. The mean age was 52.0 +/- 9.6 years. Sixty-seven percent of the patients were compliant with their devices. A significant difference was observed between the proportion of the participants compliant or non-compliant with the device, based on OSA severity (p < 0.05). Beck depression inventory (BDI) and Beck anxiety inventory (BAI) scores of the compliant patients were significantly lower than those of the non-compliant patients (p < 0.001, p = 0.044, respectively). No statistically significant difference was detected between the groups regarding individual pulmonary function tests (p > 0.05). The rates of nasal mask use, not having difficulty in tolerating CPAP, falling asleep, absence of abdominal distension, no facial sores, no air leakage, patients benefiting from the device, reduction in daytime sleepiness, and the belief that they are receiving appropriate therapy in participants compliant with the device were higher than those in non-compliant participants (p < 0.05). The rates of claustrophobia and discomfort due to pressure were significantly lower in patients compliant with the device than in the non-compliant patients (p < 0.05). Conclusion While no relationship was detected between PFT parameters and PAP therapy compliance, significant factors affecting the device compliance were detected.

SUMMARY OBJECTIVE: The aim of this study was to compare the workers in the metal and transportation sectors in terms of COVID-19 infection frequency and to examine and establish links between infection frequency and the workplace working conditions. METHODS: A survey was prepared and conducted with a questionnaire prepared on the Google Form platform consisting of questions about the pandemic among the members of the All Transport Workers’ and The United Metalworkers’ Union in Turkey. RESULTS: The number of workers diagnosed with COVID-19 was 5.8% in the transportation sector and 2.8% in the metal sector, with a significant difference (p=0.036). The percentage of workers diagnosed with COVID-19 who worked at a physical proximity less than 2 m in the transportation sector was higher than those who worked in the metal sector (p=0.014). The proportion of those who stated that there were COVID-19 patients among their colleagues and working at a physical proximity less than 2 m at the workplace was 18.2% in the transportation and 10.6% in the metal sector, with a significant difference (p=0.003), those who took time off from work was 74%, but 28.5% successively (p

Background The International Labour Organization (ILO) Classification of Radiographs of Pneumoconioses is used as the primary tool to determine compensation for pneumoconiosis in Turkey. Aims We aimed to evaluate how the ILO classification applied, but obtaining chest radiographs in the workplace for screening until the completion of compensation claim files by the referral centres, based on the ILO reading. Methods The study included 320 digital chest radiographs previously taken for screening from eight different ceramic factories and having finalised claim files by referral centres. We used an expert reference panel consisting of five ILO readers to re-evaluate all the radiographs independently using ILO standard films and reached a conclusion based on the agreement among at least three readers. The evaluation primarily included technical quality and silicosis diagnosis with an ILO 1/0 or above small profusion. The results were compared with previous findings. Results Sixty-three (20%) chest radiographs were unacceptable for classification purposes according to the ILO technical quality grades. Among the remaining 257 chest radiographs, we diagnosed 103 with silicosis (40%), while the referral centres diagnosed 182 (71%). A discrepancy was found between our results and previous evaluations. We diagnosed silicosis in 50% and 17% of the previous silicosis and normal evaluations, respectively. Conclusions Our findings suggest that the use of the ILO classification for compensation claims may be problematic due to the way of its implementation in Turkey in addition to its subjectivity., Turkish Thoracic Society (TTS), The study was funded by Turkish Thoracic Society (TTS).

SUMMARY OBJECTIVE: This study aimed to evaluate the data of Turkish health care workers practicing chest medicine on their coronavirus disease 2019 (COVID-19) status and related parameters. METHODS: This descriptive study included online survey data that the Turkish Thoracic Society conducted with its members in two phases starting in June and December 2020. The 33-item survey included demographic data, smoking status, the presence of any chronic diseases, occupation, working status, and non–work-related and work-related COVID-19 exposure characteristics. RESULTS: Of 742 responses, 299 (40.3%) reported that they had contracted COVID-19. The second survey detected a higher frequency of health care workers who had contracted COVID-19 (12.1% versus 57.4%, p

Background: There are few studies showing that the increase in particulate matters less than 10 mu m (PM10) values increases the apnea-hypopnea index (AHI). We aimed to investigate relationship between air quality parameters and the seasons with the AHI. Methods: This was a retrospective study that included 500 adults. Polysomnography (PSG) was performed on all patients. Oxygen saturation, air temperature, relative humidity, and PM10 values were recorded in Duzce for every year. The parameters of the national air quality network and sleep parameters of 500 individuals hospitalized between 2015 and 2017 were checked. Results: A total of 500 patients were included in the study, of whom 316 (63.2%) were male and 184 (36.8%) were female. While the AHI value of patients who presented during 2016 was 27.5, it had significantly declined to 20.2 in 2017 (p = .024). A significant decline was observed in AHI values of OSA patients from 2016 to 2017 (p = .043). A significant positive correlation was observed between REM-related AHI and relative humidity (r = 0.183, p = .002). Conclusions: This study showed a clear relationship between AHI and PM10 during winter when air pollution parameters are high in the region. PM10 emerged as a parameter that substantially increases the relative risk for OSA. WOS:000483191800001 2-s2.0-85071006139 PubMed: 31441672

Background. In recent years, many studies have evaluated the increasing incidence of asthma and chronic respiratory diseases among children living close to rural areas with pesticide application. Pesticide exposure in 266 children (126 girls and 140 boys) in Sanliurfa, a cotton-producing province in Turkey, was explored in this work. Four different villages spread over 40 km(2) were included. Methods. Measurements of peak expiratory flow (PEF) in 266 children were conducted in late June, before intensive pesticide applications in the cotton-producing fields. The measurements were repeated for 72 of 266 children after pesticide application in late August. PEF, particulate matter with diameter less than 2.5 mu m (PM2.5), particulate matter with diameter less than 10 mu m (PM10), temperature, humidity, and wind speed were measured. Results. After pesticide application, mean PM2.5 and PM10 values were significantly increased compared to before pesticide application (p < 0.001 for both parameters). After pesticide exposure, nasal discharge, sneezing, burning and itching in the eyes, cough, sputum production, wheezing, shortness of breath and chest tightness were significantly increased (p < 0.001). The mean PEF value was demonstrated to decrease significantly after pesticide application (p < 0.001). Moreover, significant negative correlations were noted between PEF and PM10 and between PEF and PM2.5 (p < 0.001). Conclusions. Intensive pesticide application causes respiratory dysfunction and increased respiratory complaints in children living near the affected agricultural areas, and impacts quality of life adversely. The results of this work can be used to develop an early warning system and methods to prevent respiratory disorders in children residing in the study area., Turkish Thoracic Society, The authors wish to express their thanks to the Turkish Thoracic Society for providing financial support for this work.

Ojective To investigate respiratory health problems related to pesticide exposure in the inhabitants of agricultural areas. Material and methods This study included 252 participants prior to pesticide application and 66 participants from the first group after pesticide application across four cotton farms. Symptom questionnaires were filled out by participants and respiratory function tests were measured before and after pesticide exposure. In addition, PM 10 , PM 2.5 , air temperature, and humidity were measured in all four farming villages before and after pesticide administration. Results PM 10 and PM 2.5 levels were significantly increased after pesticide application. After pesticide application, all participants’ nose, throat, eye, and respiratory complaints increased significantly. Expected forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) percentage values decreased significantly. The rates of FVC and FEV1 values lower than 80% were 23.5% and 22%, espectively, before pesticide application, and this rate increased to 42.4% and 43.1%, respectively, after pesticide application. There was a significant negative correlation between PM 10 levels and FVC, FEV1, and PEF values. After PM 2.5 pesticide application, the risk of experiencing burning in the mouth, nose, and throat increased by 2.3-fold (OR: 2.316), 2.6-fold for burning symptoms in the eyes (OR: 2.593), 2.1-fold for wheezing (OR: 2.153), and 2.2-fold for chest tightness (OR: 2.211). With increased PM 10 levels, the risk of chest tightness increased 1.1-fold (OR: 1.123). Conclusions After pesticide administration, the respiratory health of the participants deteriorated. Performing pesticide applications in agriculture with harmless methods is the most important measure to be taken to protect public health

PubMed ID: 32144590 Objective: This study aimed to determine the association between the severity of obstructive sleep apnea (OSA) and serum Clara cell protein (CC16) levels in non-smoking patients with OSA. Methods: This prospective study included non-smoking patients who presented with sleep-related disturbances and underwent polysomnography (PSG). The serum CC16 level was measured and its relationship to PSG parameters was investigated. Results: The study included 128 patients (83 men) with a mean age of 48.4 ± 11.9. OSA was detected in 66 men (70%) and 29 women (30%) (p = 0.051). The severity of OSA was mild in 32 (25%), moderate in 28 (22%), and severe in 35 (27%) of the patients. There was no significant difference in CC16 levels between the OSA group (1746 ± 1006) and the OSA negative group (1721 ± 1201, p = 0.91) levels. There was no significant difference between the CC16 levels of the each four groups. Mean serum CC16 levels were significantly lower in OSA negative men than OSA positive men (777 vs 1462, p = 0.005). No significant difference was observed in CC16 values according to OSA severity in women. Conclusion: The serum CC16 level does not differ between non-smoking OSA patients and OSA negative patients. © 2020, Springer Nature Switzerland AG.

WOS: 000435396300006 PubMed: 30020040 Introduction: Welding produces miscellaneous gases and particles that has various impact on respiratory system and long term exposure may result "welders'lung". The aim of this study is to describe the radiological findings of welders' and make an awereness for welders radilogical findings. Materials and Methods: The clinical and radiological findings of welders' who had hospital applications with respiratory symptoms between January 2010-January 2017 were evaluated retrospectively. Results: A total of 16 male welders with mean age 37 +/- 8 years had the mean duration of welding occupation 12 +/- 7 years. The most common symptoms were coughing (87%), sputum production (63%) and dyspnoea (63%). Thirteen welders were working in shipyards and 3 in construction business and other workplaces. Three (19%) patients had rhonchi on physical examination and these patients had decreased FEV1/FVC values below 70% on spirometry. Poorly-defined centrilobular micronodules that were not clearly visible on chest radiographs observed on thorax high resolution computed tomography. Bronchoscopy was performed to 7 patients. Iron-positive pigment granules and ferruginous bodies were revealed in 3 patients' bronchoalveolar lavage. Conclusion: Welders' chest X-ray deserve a closer look. In pulmonary radiology, there may be radiographical findings ranging from small ill defined nodules to groundglass opacites. Physcians should look more careful to welders' chest X-ray and incase of suspicious findings best can be detected on high HRCT. An awareness for the radiological findings will also reduce interventional procedures in these patients hereby, occupational history must be included in daily practice of physicians.

Patients and methods: A total of 509 adult patients with COPD (n=328) or asthma (n=181) who were currently using an inhaler device were included in this study. Data on patient demographics, duration of disease, type and duration of inhaler therapy, and assessment of inhaler technique were recorded. Results: Metered dose inhaler (MDI) was the most common type of inhaler used by a similarly high percentage of patients in both COPD (83.2%) and asthma (77.3%) groups. Failure to exhale before inhaling through device (75.8% and 68.5% for MDIs; 73.2% and 71.8% for Aerolizer®/Handihaler®; 53.1% and 66.7% for Turbuhaler®) was the most common error in inhaler technique, in both COPD and asthma groups. Device-specific errors in inhaler techniques were more common in asthma patients as compared with COPD patients, particularly for MDIs (P-values ranged from 0.046 to 0.0005), as associated with female gender (failure to press the buttons on both sides of Aerolizer®/Handihaler®, P=0.006), shorter duration of disease (failure to hold MDI or head in a vertical position, P

Introduction and aim. The presented study was undertaken to investigate the respiratory health problems in family barns with one or more cows and at least one family member working in the barn. Methods. 150 workers (128 female, 22 male) from 4 villages of Yığılca district near the city of Düzce in north-west Turkey were enrolled in this study between October – December 2011. An Occupational and Environmental Chest Diseases questionnaire developed by the American Thoracic Society, pulmonary function test, physical examination and investigation for nasal eosinophil were performed in all subjects. Results. The mean age of workers was 47.7 ± 14.2 years. Cough was present in 24% of subjects. The rates of phlegm, wheezing, chest tightness and dyspnea were 13.3%, 6%, 6% and 27.3%, respectively. Obstructive ventilatory pattern was observed in 37 workers (24.6%). 43 workers (28.6%) showed restrictive ventilatory pattern. Nasal eosinophilia was detected in 47.3% (71/150) of the subjects. Pulmonary functions of workers with nasal eosinophilia did not differ from the other workers. There were statistically significant negative correlations between the duration of working in barns and respiratory functions. Conclusions. Pulmonary functions of barn workers have been found to be decreased related to the duration of barn working. Furthermore, respiratory symptoms increased in relation with both barn working and biomass consumption. Precautions should therefore be taken to ventilate both barns and houses.

Aim. This study aimed to assess the long-term respiratory effects of tear gases among the subjects with history of frequent exposure.Materials and Methods. A questionnaire by NIOSH and pulmonary function tests was performed in 93 males exposed to the tear gases frequently and 55 nonexposed subjects.Results. The mean numbers of total exposure and last 2 years exposure were8.4±6.4times,5.6±5.8times, respectively. Tear gas exposed subjects were presented with a higher rate for cough and phlegm more than 3 months (24.7% versus 11.3%,P>0.05). Mean FEV1/FVC and % predicted MMFR in smoker exposed subjects are significantly lower than those in smoker controls (81.7% versus 84.1%,P=0.046and 89.9% versus 109.6%,P=0.0004, resp.). % predicted MMFR in nonsmoker exposed subjects is significantly lower than that in nonsmoker controls (99.4% versus 113.1%,P=0.05). Odds ratios for chest tightness, exercise dyspnea, dyspnea on level ground, winter morning cough, phlegm, and daily phlegm were increased almost 2 to 2.5 folds among tear gas exposed subjects.Conclusion. The rates for respiratory complaints were high in the case of the exposure to the tear gases previously. Tears gas exposed subjects were found to be under the risk for chronic bronchitis.

Yavuz, Özlem (Balikesir Author), Aim. Previous studies have shown a higher sensitization rate to hazelnut in processing workers but no relation was found between the respiratory symptoms in workplace and hazelnut sensitization. Material and Method. To evaluate the association between the hazelnut sensitization and workplace-related respiratory complaints, hazelnut processing workers had undergone a questionnaire included work-related respiratory symptoms, smoking history, pulmonary function testing, and measurement of serum IgE antibodies against hazelnut. Results. This study consisted of 88 hazelnut processing workers (79 females and 9 males), aged 14-59 years (Mean +/- SD: 33.8 +/- 10.5 years). The mean working duration was 38.8 +/- 36.6 months (min: 1-max: 180). Specific IgE against hazelnut allergens was positive in 14 of cases (17.1%). There was no significant difference between the cases with and without specific IgE against hazelnut allergens regarding respiratory symptoms, history of allergy, smoking status and spirometric values. Conclusion. 17.1% of the hazelnut processing workers were seropositive against hazelnut. Being sensitized to hazelnut was not found to be associated with work-related respiratory symptoms in this study. Further studies are needed in hazelnut workers respiratory health to search topics other than asthma.

WOS: 000264777200009, PubMed ID: 19367045, Diesel exhaust (DE) has been accused for various health outcomes including exacerbation of asthma, chronic bronchitis. Exposure to DE has long-term effects on lung development in children and reductions in lung function have been reported. The aim of the study was to evaluate the annual changes in forced expiratory flows among toll collectors in Duzce city from 2002 to 2005. Annual FVC, FEV1 and MMF changes in smoker and nonsmoker 58 toll collectors and 37 controls selected among men who worked in the same company as officer have been followed up. No significant changes were seen in expiratory flows among smoker-nonsmoker toll collectors and controls (p>0.05). Annual FVC, FEV1 and MMF changes were not significantly different between smoker and nonsmoker toll collectors. Twelve toll collectors (20.7%) in the study group and 4 (10.8%) controls were found to have FEV1 and FVC below longitudinal lower limit of normal. The difference between groups did not reach statistically significance (p>0.05). Toll collectors (18/58) and controls (15/37) with spirometric measurements for three times showed no difference according to the rate of annual difference in either FEV1 (-21.3 +/- 133.1 ml/yr vs -44.3 +/- 166.6 (ml/yr) or FVC (13.2 +/- 202.9 ml/yr vs. -16.1 +/- 204.2 ml/yr). Further investigations including large groups with long term follow up are needed to observe annual FVC, FEV1 and MMF changes among toll collectors.

WOS:000223257800005 PubMed: 15308827 Serum Oxidant and Antioxidant Levels in Diesel Exposed Toll Collectors: Peri ARBAK, et al. Department of Chest Diseases, Abant Izzet Baysal University, Duzce School of Medicine, Turkey-it has been suggested that exposure to diesel exhaust may lead to adverse effects due to the generation of oxidants. To evaluate the end products of oxidative stress in DE exposure, toll collectors who are considered a high risk group in regard to occupational toxins were compared to controls who had office-based occupations in the same company in this cross sectional study. A total of 38 toll collectors constituted the study group. All subjects were male. The toll collectors and 29 controls were similar regarding age, smoking status and duration of work. All subjects underwent a clinical examination and an interviewer-administrated questionnaire regarding respiratory symptoms, past medical and occupational history, and pulmonary function tests were performed in all subjects. Serum malondialdehyde (MDA), nitrite+nitrate and vitamin E levels were measured. Toll collectors showed higher serum MDA (5.76 +/- 2.15 mumol/L vs. 3.07 +/- 0.76 mumol/L, p=0.0001) and nitrite+nitrate levels (96.50 +/- 45.54 mumol/L vs. 19.32 +/- 11.77 mumol/L, p=0.0001) than controls. Vitamin E levels were similar in toll collectors and controls (10.57 +/- 3.44 mg/L and 9.72 +/- 2.44 mg/L, respectively, p=0.267). There was no difference between groups in terms of the findings of clinical examinations and respiratory symptoms. In pulmonary function parameters, only peak expiratory flow (PEF) in toll collectors was significantly lower than that of controls (88.9% predicted and 104.2% predicted, respectively, p=0.012). In conclusion, we suggest that serum MDA and nitrite+nitrate levels may be used as biological markers of oxidative stress related to DE exposure, but prospective controlled clinical studies are necessary to clarify the possible association between concentrations of MDA and nitrite+nitrate and pulmonary diseases related to DE exposure.

Background: Clinical and epidemiological studies indicate that obstructive sleep apnea syndrome (OSAS) has a strong genetic basis. Objectives: To investigate the apolipoprotein E (APOE) alleles as a genetic risk factor in OSAS. Methods: A total of 73 patients (37 male) were included. All underwent full-night polysomnography and were evaluated for APOE alleles. Results: The mean age was 51 ± 12 years. Forty-two of the patients had OSAS. The APOE3 allele was found in 97.3% (71/73) of the study population. The most common APOE genotype was E3/E3 (55/73, 75.3%). Compared to the individuals with no APOE2 alleles (E3/E3, E3/E4), the individuals with at least one APOE2 allele (E2/E3, E2/E4) had a 9.37-fold greater OSAS risk (OR = 9.37, 95% CI 1.13-77.7, p = 0.019). The individuals with APOE2 alleles (E2/E3, E2/E4) compared to the individuals with only an E3/E3 allele genotype had a 10-fold greater OSAS risk (OR = 10.3, 95% CI 1.24-86.61, p = 0.0308). Compared to the individuals with no APOE4 alleles (E2/E3, E3/E3), the individuals with APOE4 alleles (E2/E4, E3/E4) had a high but insignificant risk for OSAS (OR = 2.9, 95% CI 0.55-15.05, p = 0.286). The individuals with APOE4 alleles (E2/E4, E3/E4) compared to APOE3 alleles (E3/E3) had an increased but insignificant risk for OSAS (OR = 3.62, 95% CI 0.96-19.05, p = 0.127). Conclusion: Specific APOE genotypes are associated with OSAS in a high-risk population.

WOS: 000343538700001, PubMed: 25105168, Background and Aim. It was observed that occupation and smoking increased each other's effects on the development of airway diseases. We aimed to search the relationship between respiratory symptoms, smoking, and occupation. Materials and Methods. 225 employees in Duzce, Turkey, were applied a survey questioning respiratory complaints, pulmonary function tests (PFTs) and cotinine measurements in urine. Results. Cough (26.7%), phlegm (30.7%), and chest tightness (21.3%) were encountered more in carpenters compared to other groups and phlegm was statistically higher at significant level compared to other groups. The complaints of cough (30.4%), phlegm (27.4%), and chest tightness (21.5%) were significantly higher in individuals whose cotinine level was above 500 ng/mL and forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) ratio, maximum midexpiratory flow rate (MMFR) values were significantly lower. Dyspnea complaint of auto painters whose cotinine level was below 500 ng/mL was significantly higher and also expected MMFR% value of this group was significantly lower compared to other groups. While age had independent effect on respiratory function tests, type of the job was found to be independently effective on MMFR. Conclusion. Smoking increases respiratory complaints of employees. In auto painters, the occupation causes airway disease regardless of smoking.

Design: Case series. Setting: School of Medicine, Duzce University, Turkey. Patients: Twenty-one consecutive primary open-angle glaucoma patients (12 females and 9 males) who attended the out-patient clinic of the Department of Ophthalmology between July 2007 and February 2008 were included in this study. All patients underwent polysomnographic examination. Results: The prevalence of obstructive sleep apnoea syndrome was 33.3% in patients with primary open-angle glaucoma; the severity of the condition was mild in 14.3% and moderate in 19.0% of the subjects. The age (P = 0.047) and neck circumference (P = 0.024) in patients with obstructive sleep apnoea syndrome were significantly greater than those without the syndrome. Triceps skinfold thickness in glaucomatous obstructive sleep apnoea syndrome patients reached near significance versus those without the syndrome (P = 0.078). Snoring was observed in all glaucoma cases with obstructive sleep apnoea syndrome. The intra-ocular pressure of patients with primary open-angle glaucoma with obstructive sleep apnoea syndrome was significantly lower than those without obstructive sleep apnoea syndrome (P = 0.006 and P = 0.035 for the right and left eyes, respectively). There was no significant difference in the cup/disc ratio and visual acuity, except visual field defect, between primary open-angle glaucoma patients with and without obstructive sleep apnoea syndrome. Conclusions: Although it does not provide evidence for a cause-effect relationship, high prevalence of obstructive sleep apnoea syndrome in patients with primary open-angle glaucoma in this study suggests the need to explore the long-term results of coincidence, relationship, and cross-interaction of these two common disorders.

Sarkoidoz, idiyopatik granülomatöz bir hastalıktır. Genellikle akciğer tutulumu vardır. Tanısı, granülomatöz inflamasyonun bilinen diğer nedenlerinin dışlanması gerekliliği yüzünden zor olabilir. Çok merkezli çalışmamızda sarkoidozun klinik görünümleri ve tanısal yaklaşımlarının değerlendirilmesi amaçlandı. Çalışma protokolü internet üzerinden araştırmacılara gönderildi ve yeni tanı almış sarkoidoz olgularına ait bilgilerini göndermeleri istendi (klinik, radyolojik ve tanısal). İki yıl içinde 293 hasta verisi toplandı. Solunumsal yakınmalar, hastaların %73.3’ünde bulundu ve öksürük en sık yakınmaydı (%53.2), dispne (%40.3) ikinci sıklıktaydı. Konstitüsyonel yakınmalar hastaların yarısında görüldü. En sık olanı yorgunluktu (%38.6). En yaygın bulgu eritema nodozum (%17.1) idi. En sık akciğer radyogramı bulgusu bilateral hiler lenfadenomegali (%78.8) idi. Radyolojik evrelemede hastaların çoğunluğunun Evre I ve Evre II olduğu bulundu (sırasıyla %51.9 ve %31.7). Histolojik doğrulama 265 (%90.4) hastada gerçekleşmişti. Bronkoskopilerin üçte biri normal iken, mukozal hiperemi (%19.8) ve bronş duvarının dışarıdan basısı (%16.8) yaygın anormal bulgular idi. Sık kullanılan örnekleme yöntemleri arasında yer alan mediastinoskopide tanı başarısı %100 idi. En sık kullanılan tanı yöntemi olan transbronşiyal biyopsinin başarı oranı %48.8 idi. Sarkoidoza çok yönlü yaklaşım, sık ve seyrek rastlanan bulguları göz önünde bulundurularak ayırıcı tanı listelerinde yer alması, olası tutulmuş alanlara yönelik tanısal incelemelerin organizasyonu ve birarada çalışan ekip üyelerinin konunun uzmanı olması sayesinde iyileştirilir., 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 favour multimodality diagnosis.

Serum levels of CA 19.9, CA 25 and CEA were determined by the chemiluminescent immunometric method. Based on values obtained from pulmonary function tests, the patients were divided into 3 groups: moderate (21), severe (18) and very severe (14). Data were analyzed with a Kruskal-Wallis one-way analysis of variance test and Mann-Whitney U test. Results: The mean serum levels of CA 125 and CA 19.9 were significantly higher in patients with very severe COPD (p = 0.013 and p = 0.017, respectively) than in patients with severe and moderate COPD (p < 0.05). Patients with cor pulmonale had significantly high mean serum levels of CEA, CA 19.9 and CA 125 (p < 0.05). Patients using a long-acting beta-agonist and theophylline showed significantly higher mean serum levels of CA 125 than patients who were not (p < 0.05). Conclusion: Data showed that the increased serum tumor markers in patients with COPD might be due to the severity of COPD, medication and cor pulmonale. Copyright (c) 2009 S. Karger AG, Basel

Aims and backgroundTo evaluate the relationship between delayed diagnosis and the degree of invasion and survival in lung cancer.MethodsOne hundred and three patients (96 men) with lung cancer were included. Stages in the diagnosis of lung cancer were classified as follows: symptom-to-doctor interval, i.e., the interval from the first symptoms related to the presence of lung cancer to the first consultation with a medical professional; doctor-to-diagnosis interval, i.e., the interval between the first medical visit and confirmation of the diagnosis; and diagnosis-to-treatment interval, i.e., the interval between diagnosis and complete TNM staging and treatment. The symptom-to-treatment interval (STI) was the sum of the 3 intervals. The degree of invasion was determined by the TNM classification.ResultsThe patients were followed up for a mean period (± SD) of 7.4 ± 8.7 months. Seventy-six (74%) patients were diagnosed with non-small cell lung cancer (NSCLC) and 27 patients (26%) with small cell lung cancer (SCLC). The mean length of STI was 120 ± 101 days (median, 90). The mean length of the symptom-to-doctor interval was 63 ± 62 days (median, 45), while the doctor-to-diagnosis and diagnosis-to-treatment intervals were 41 ± 82 days (median, 10) and 16 ± 12 days (median, 12), respectively. When the STIs of the patients were correlated with tumor stage, tumor invasion, lymph node involvement and metastasis, no significant differences were found. Patients with an STI longer than 60 days had a significantly longer survival. Regarding the type of lung cancer and STI, the median survival was shorter in patients with an STI of less than 60 days both in NSCLC and SCLC, although this was not statistically significant in SCLC.ConclusionsThe shorter the diagnostic interval, the shorter was the median survival in our study. The reason for the apparent discrepancy between poor prognosis of lung cancer patients in spite of early diagnosis might be much faster progression of the disease itself.

Annakkaya, Ali Nihat N/0000-0002-7661-8830; BILGIN, CAHIT/0000-0003-2213-5881 WOS: 000243291500002 PubMed: 17078025 Purpose. To assess the effects of exposure to exhaust particles on intima-media thickness of the common carotid artery in highway toll collectors, Methods. Sixty-one highway toll collectors (HTCs) between 24 and 56 years of age (mean, 36.2 +/- 7.3) and 48 controls between 24 and 64 years of age (mean, 42.6 +/- 10.6) were evaluated with gray-scale sonography to measure intima-media thickness (IMT) of the common carotid artery (CCA). Subgroups were categorized according to duration of exhaust exposure and further divided according to tobacco use. Results. CCA IMT was higher (0.8 +/- 0.2 mm) in HTCs than in the control group (0.6 +/- 0.1 mm; p < 0.001) and remained higher when subgroups with similar smoking habits were compared. In HTCs, IMT was greater when the number of years working in tollbooths was greater (p = 0.023). IMT was lower in HTCs with an exposure duration of < 10 years compared with a duration of 10-20years (p = 0.017) or > 20years (p value not significant). Conclusion. Air pollution has a widely acknowledged negative effect on humans. This study confirms that exposure to exhaust particles might cause wall thickening of carotid arteries.

To evaluate the relation between infectious agents and reproductive health hazards for health care workers (HCWs), a cross-sectional study consisting of 73 HCWs and 65 bureau workers was conducted. The reproductive health problems of both groups were compared using a questionnaire, and serologic examinations for measles, varicella and hepatitis B were performed. There were no differences between the two groups according to the rate of seropositivity of measles and varicella (P0.05). The prevalence of anti-HBc seropositivity was significantly higher among HCWs than controls (31.5 versus 16.9%). There were no differences between seropositive and seronegative subgroups of measles, varicella and hepatitis B regarding the rates of normal delivery time, preterm and postterm delivery and stillbirth. Subjects seropositive for anti-HBc showed a higher spontaneous abortion rate than those who were seronegative (38.2 versus 16.3, P = 0.009). Although these data showed that HCWs had a high rate of anti-HBc seropositivity and that the rate of spontaneous abortion was associated with past hepatitis B virus infection, further studies including larger populations are needed. We considered that it should be strongly recommended that all HCWs be vaccinated against this virus, and future studies should be focused on the relationship between infectious diseases and reproductive health problems in HCWs.

The purpose of this study was to investigate various factors, including demographical, socioeconomical, clinical and radiological features, of adherent and nonadherent patients with tuberculosis (TB) who were admitted to a university hospital between 1998 and 2003. One hundred and one patients (65.5%) and 53 patients (34.5%) met the criteria of adherence and nonadherence, respectively. A higher rate of adherence was observed among females than males (79.2 versus 58.4%, respectively, P = 0.012). Older patients were more nonadherent (P = 0.008). The adherence rate in non-smokers was significantly higher than that of smokers (81.4 and 52.4%, respectively, P = 0.000). Patients who underwent "family screening" were more adherent (75.7%) than those (39.5%) who did not (P = 0.000). Patients with pleurisy had higher adherence rates (81.3%), followed by patients with pulmonary TB (65.0%), while patients with extrarespiratory TB had the lowest adherence rates (45.5%) (P = 0.024). The presence of cough was significantly associated with adherence (P = 0.049). A significantly higher adherence rate was observed in patients without hemoptysis (P = 0001). A univariate logistic regression confirmed that age, smoking, family screening, type of TB, cough and hemoptysis had significant independent effects on the adherence to treatment of TB. High-risk patients may be identified and interventions tailored to promote adherence before concluding that the patient is willfully refusing treatment.

Adverse respiratory reactions have been reported with intravascular radiographic contrast media. The aim of the present study is to assess the effects of iohexol on pulmonary functions in patients undergoing diagnostic coronary angiography (CA).30 patients enrolled in the study. The respiratory functions of the patients were measured at three different stages during angiography (before, immediately after and 2 h later) and arterial blood gas analyses were performed at six stages during CA (before, immediately after the insertion of angiography catheter, 2 min after the injection of contrast agent, at the end of angiography, an hour and 2 h after angiography). A single, experienced angiographer performed the angiography procedures via radial artery route. Totally six multiple angled views of the left and right coronary arteries were recorded in all patients by hand injection. None of the patients were performed ventriculography.Angiography caused significant reduction in forced expiratory volume in 1 sec [FEV1] (from 103 +/- 15 to 95 +/- 17, p0.01), forced vital capacity [FVC] (from 99 +/- 13 to 95 +/- 18, p0.05) and maximum mid-expiratory flow rate [MMF] (from 95 +/- 33 to 84 +/- 29, p0.01) whereas there were no significant changes in the mean FEV1/FVC ratios at different stages of angiography. Statistically significant decrease in PaO2 (from 91 +/- 10 to 85 +/- 13 mmHg, p0.01) and arterial O2 saturation (from 97 +/- 1% to 96 +/- 1%, p0.01) were also observed. Data in present study showed a clinically insignificant but statistically significant restrictive impairment in pulmonary functions.Diagnostic CA using iohexol decreases ventilatory functions in a small but significant extent in patients without any overt pulmonary disease.

WOS: 000230200400002 PubMed: 15899162 BACKGROUND AND OBJECTIVE: Sarcoidosis is a systemic granulomatous disease of unknown etiology. Aims of this prospective study are to evaluate degree of impairment in pulmonary function tests (PFT), arterial blood gas analysis (ABG), respiratory muscle strength, exercise capacity and correlation of these parameters with radiological stages; to further evaluate the use of cardiopulmonary exercise testing in assessment of extent of pulmonary disease; and to discuss the pathophysiologic mechanisms of limitation in exercise capacity in patients with sarcoidosis. PATIENTS AND METHOD: 29 patients with sarcoidosis were grouped according to their radiological stages (stage I: group 1; stage II, group 2; stage III, group 3). Group 1, 2 and 3 included 11, 13 and 5 patients, respectively. PFT, cardiopulmonary exercise testing and ABG were performed for each patient. RESULTS: Evaluation of all patients showed a significant decrement in exercise capacity. Patients in stage III had decreased diffusing capacity and exercise capacity. There was limitation in exercise capacity in stage I patients who had completely normal spirometry and diffusing capacity. We also found a correlation between radiological stages of the disease and exercise capacity, diffusing capacity and ABG. CONCLUSIONS: Exercise capacity is impaired also in early stages of sarcoidosis and it was found to be the earliest impaired physiological parameter in sarcoid patients. Exercise intolerance, having mutifactorial basis, is correlated with radiological stages. Circulatory impairment and impaired heart rate response to exercise have effects on limitation in exercise capacity. Especially in advanced radiological stages of disease, ventilatory and gas exchange impairment also seems to be effective on limiting exercise in patients with sarcoidosis.

WOS: 000224419300005 PubMed: 15363002 Objective: There have been controversial reports regarding the relationship between exercise tolerance and resting pulmonary function in patients with COPD. The aim of this study was to examine the relationship between resting pulmonary function tests (rPFT) and cardiopulmonary exercise testing parameters (CETP) and their value in estimating exercise tolerance of patients. Methodology: In total, 45 patients with COPD (nine females, 36 males; mean age 61.2 +/- 11.2) and 21 healthy subjects (four females, 17 males; mean age 60.3 +/- 9.7) as a control group were studied. COPD patients (group I) were divided into three subgroups according to their FEV1 (mild/group II: FEV1 60-79% of predicted; moderate/group III: FEV1 40-59%; severe/group IV. FEV1 < 40%). In controls FEV1 was greater than or equal to 80%. Results: There were significant correlations between FEV1 and CETP in group III (maximal O-2 consumption (mVO(2)), r = 0.35, P < 0.005; total treadmill time (TTT), r = 0.31, P < 0.01; total metabolic equivalent values (TMET), r = 0.29, P < 0. 01)) and in group IV (mVO(2), r = 0.49, P < 0.001; TTT, r = 0.45, P < 0.005; TMET, r = 0.31, P < 0.01; peak heart rate (pHR), r = 0.29, P < 0.02; frequency of ventricular extrasystole (fVES), r = -0.27, P < 0.05). Additionally, in group IV there were significant correlations between PaO2 and CETP (mVO(2), r = 0.41, P < 0.02; TTT, r = 0.38, P < 0.03; TMET, r = 0.31, P < 0.05; pHR, r = 0.29, P < 0.05; fVES, r = -0.28, P < 0.05). Conclusion: There are significant correlations of resting FEV1% predicted and PaO2 Values with CETP in patients with moderate and severe COPD and these parameters may also have a role as indicators of exercise tolerance in these COPD patients.

This prospective study was designed to evaluate the effects of hyperthyroidism on flow-volume loops in nonasthmatic 20 patients with hyperthyroidism. Thyroid related hormones (Total T3, Total T4 and TSH), thyroid gland volumes with ultrasonography, circumference of neck values and flow-volume loops were obtained at the beginning and after three months of antithyroid treatment. Propylthiouracil treatment was followed by a statistically significant decrease in thyroid gland volume and circumference of neck (p0.001 and p0.001, respectively). The most significant result was improvement of maximum midexpiratory flow rate (MMEFR) after propylthiouracil therapy for three months (p= 0.003). Increases in mean forced expiratory flow after 25% of FVC has been exhaled (FEF25), mean forced expiratory flow after 75% of FVC has been exhaled (FEF75) values were found consistent with the overall improvement in expiratory flow parameters (p= 0.044, p= 0.012 respectively). In conclusion, we speculated that improvement of expiratory flow parameters might be the earlier changes in flow volume loops of patients who were treated with propylthiouracil for hyperthyroidism.

This study was designed to evaluate the effects of furniture production, mainly including fir tree (aberia mulleriana), on respiratory health of young workers and to compare the results with those obtained from previous studies. Sixty-four furniture-decoration students (57 males and 7 females) and 62 controls (54 male, 8 female) from different departments in the same school were included into the study. All participants were assessed with a questionnaire (concerning history of occupational exposure, work-related respiratory and other symptoms, smoking history, previous asthma history), full physical examination, spirometric evaluation and chest radiograph. Participants then performed serial monitoring of peak expiratory flow rates (PEFR) at work and away from work within a month. Mean age of students was 20.9 +/- 3.7 years, 20.5 +/- 2.6 years in controls. There was no difference between study and control groups with regard to age, gender, smoking status and previous asthma history. Reported cough (23.4 % vs. 8.1 %) and shortness of breath (18.8 % vs. 6.5 %) were significantly higher in furniture-decoration students than in controls (p = 0.016 and p = 0.034, respectively). Furniture-decoration students had higher conjunctivitis (34.4 % vs. 9.7 %, p = 0.001) and rhinitis (34.4 % vs. 19.4 %, p = 0.044) history when compared with controls. Both students and controls were normal in terms of respiratory examination. PEF recordings were performed for approximately one month. Diurnal variability greater than 20 % was seen in 12/64 (18.7 %) of students at work, whereas it was detected in 4/62 (6.4 %) of controls (p = 0.034). When comparing for the presence of diurnal variability greater than 20 % in weekends, no difference was found between groups (p = 0.457). In conclusion, early detection of work-related respiratory changes by serial monitoring of peak expiratory flows should save the workers from hazardous respiratory effects of the furniture production, especially in young population.

The bacillus Calmette-Guerin (BCG) vaccine is administered and recommended for the prevention and control of tuberculosis in developing countries with high-risk settings. A new general BCG vaccination programme against tuberculosis has been introduced since 1997 in Turkey. The aim of this study was to evaluate the BCG vaccination status in Düzce and to analyze contributing factors for the vaccination programme. BCG screening were performed in 1100 8th class students from nine primary schools of Düzce city centre and seven counties. BCG scar presence was taken as authoritative for vaccination status. BCG vaccination ratio was 0.94. Of 1100 students, 1030 had BCG scars; 478 had single scar, 536 had two scars and 16 had three scars. The significant negative correlation was observed between the BCG administration ratio and the number of children under age of 15 per health personnel (r= -0.771, p= 0.025). Furthermore, based on some published studies marked regional variation of BCG vaccination status in Turkey was also discussed in this article.

Aims and backgroundMany prognostic factors have been evaluated both for SCLC and NSCLC. The prognostic significance of blood group antigen expression of tumor tissues has been studied particularly in NSCLC, yielding divergent results. The aim of the present study was to investigate the prognostic value of the tumoral expression of blood group antigens ABH in lung cancer.MethodsThe presence of blood group antigens was assessed immunohistochemically in paraffin-embedded tumor samples from 92 patients diagnosed between 1996 and 1997. Monoclonal antibodies were used to detect blood group antigens.ResultsThe median survival was longer in NSCLC patients whose tumors were positive for blood group antigen A (P = 0.009). Since the expression of blood group antigen A in tumor cells was limited to patients with type A or AB blood, survival analysis of these patients showed survival to be longer in non-small cell lung cancer patients with blood group antigen A-positive tumors (P = 0.0019).ConclusionsExpression of blood group antigen A in tumor cells is an important, favorable prognostic factor in patients with non-small cell lung cancer, which could be useful to stratify patients with blood group A or AB according to possible outcome, and to guide therapeutic decision-making. The expression of blood group antigens ABH should be evaluated in larger series of lung cancer patients (including small and non-small cell lung cancer) with all blood types.
