Bronchiectasis in Türkiye: Data from a Multicenter Registry (Turkish Adult Bronchiectasis Database).

Background: Bronchiectasis is a chronic lung disease characterized by permanent bronchial wall dilatation. Although it has been known as an orphan disease, it has recently gained attention because of registry-based studies and drug research. Aims: We aimed to use a multicenter database to analyze and compare data regarding the etiology, associated comorbidities, microbiological characteristics, and preventive strategies of bronchiectasis in Türkiye to those of other countries. Study Design: A multicenter prospective cohort study. Methods: The multicenter, prospective cohort study was conducted between March 2019 and January 2022 using the Turkish Adult Bronchiectasis Database, in which 25 centers in Türkiye participated. Patients aged > 18 years who presented with respiratory symptoms such as cough, sputum, and dyspnea and were diagnosed with non-cystic fibrosis bronchiectasis using computed tomography were included in the study. Demographic information, etiologies, comorbidities, pulmonary functions, and microbiological, radiological, and clinical data were collected from the patients. Results: Of the 1,035 study participants, 518 (50%) were females. The mean age of the patients was 56.1 ± 16.1 years. The underlying etiology was detected in 565 (54.6%) patients. While postinfectious origin was the most common cause of bronchiectasis (39.5%), tuberculosis was identified in 11.3% of the patients. An additional comorbidity was detected in 688 (66.5%) patients. The most common comorbidity was cardiovascular disease, and chronic obstructive pulmonary disease (COPD) and bronchiectasis was identified in 19.5% of the patients. The most commonly detected microbiological agent was Pseudomonas aeruginosa (29.4%). Inhaled corticosteroids (ICS) were used in 70.1% of the patients, and the frequency of exacerbations in the last year was significantly higher in patients using ICS than in nonusers (p < 0.0001). Age [odds ratio (OR): 1.028; 95% confidence interval (CI): 1.005-1.051], cachexia (OR: 4.774; 95% CI: 2,054-11,097), high modified medical research council dyspnea scale score (OR: 1,952; 95% CI: 1,459-2,611), presence of chronic renal failure (OR: 4,172; 95% CI: 1,249-13,938) and use of inhaled steroids (OR: 2,587; 95% CI: 1,098-6,098) were significant risk factors for mortality. Mortality rates were higher in patients with COPD than in those with no COPD (21.7-9.1%, p = 0.016). Patients with bronchiectasis and COPD exhibited more frequent exacerbations, exacerbation-related hospitalizations, and hospitalization in the intensive care unit in the previous year than patients without COPD. Conclusion: This is the first multicenter study of bronchiectasis in Türkiye. The study results will provide important data that can guide the development of health policies in Türkiye on issues such as infection control, vaccination, and the unnecessary use of antibiotics and steroids.

Does one year change in quality of life predict the mortality in patients with chronic obstructive pulmonary disease?-Prospective cohort study.

BACKGROUND: Subjects with chronic obstructive pulmonary disease (COPD) present increased mortality and poor health-related quality of life (HRQoL) as compared with the general population. The objective of this study was to evaluate whether an improvement in QoL after 1 year of proper management is a predictor of survival in a cohort of patients followed up for 10 years. METHODS: In this prospective study, 306 COPD patients were assessed for eligibility between January 2003 and September 2003. Thirty-five patients were excluded due to failure to meet inclusion criteria or declining to participate and 20 patients were also excluded subsequently because they could not complete the questionnaire. Two hundred and fifty one patients were assessed at the beginning. St. George Respiratory Questionnaire (SGRQ) and pulmonary function test (PFT) were performed at the initial visit and the end of the first year. Mortality information was obtained from hospital records and direct family interviews. RESULTS: A comparison between respiratory diseases mortality according to baseline paramaters reveals that age and presence of cardiac comorbidity indicates a higher risk of death and associated with worse QoL. After a cox regression analysis, the relative risk of death of any cause related to baseline QoL score was 1.042 (95% CI: 1.028-1.057), and 1.030 (95% CI: 1.011-1.050) for respiratory cause mortality. However, the relative risk of death when there was a deterioration in QoL after one year of follow up was 1.175 (95% CI: 1.130-1.221) for all-cause mortality and 1.214 (95% CI: 1.151-1.280) for respiratory cause mortality. CONCLUSIONS: A QoL worsening in the initial year of follow up more strongly predicts 10-year mortality of any cause and for respiratory diseases than the baseline assessment alone predicts, among patients with COPD.

[Smoking prevalence of elementary school students in Manisa]. / Manisa ili ilkögretim ögrencilerinde sigara içme prevalansi.

INTRODUCTION: In this study it is aimed to evaluate the prevalence of smoking, factors affecting smoking status, and the attitudes of the elementary school students towards the smoking prohibition law which was approved in July 2009, in city. MATERIALS AND METHODS: The universe of this descriptive study was 6th-7th-8th class, 8236 urban and 4937 semi-urban, total 13.173 elementary schools students in city center. Study population was determined on the basis of a previous study in which the smoking trial prevalence was found 17.5%, 831 students in 6 urban 3 semi-urban, total 9 schools were chosen randomly. A questionnaire was prepared investigating smoking status, the effects of smoking and family history. Among the 9 chosen schools, the questionnaire was applied to 615 students. SPSS 14.0 statistical package was used. RESULT: Forty-seven percentages of the students were female. Prevalence of smoking trial was found 23.5% (16% in urban, 35% in semi-urban schools) while the prevalence of smoking was 7.1% (1.7% in urban, 15.7% in semi-urban schools). Mean age of first smoking trial was 10.04 ± 2.3. The smoking prohibition law was supported by 86.6% of the students, the warnings on the cigarette package was thought to be effective by 43.3% students and 35.2% of the students were exposed to passive smoke. Male gender, social status, education level of the family, smoker family member or close friends were found to be important risk factors for smoking prevalence of the students. CONCLUSIONS: The early onset of smoking should guide the smoking struggle be concentrated in elementary school especially in semi-urban areas where the smoking prevalence is high.

Antibiotic treatment outcomes in community-acquired pneumonia

Background/aim: The optimal empiric antibiotic regimen for patients with community-acquired pneumonia (CAP) remains unclear. This study aimed to evaluate the clinical cure rate, mortality, and length of stay among patients hospitalized with community- acquired pneumonia in nonintensive care unit (ICU) wards and treated with a ß-lactam, ß-lactam and macrolide combination, or a fluoroquinolone. Materials and methods: This prospective cohort study was performed using standardized web-based database sheets from January 2009 to September 2013 in nine tertiary care hospitals in Turkey. Results: Six hundred and twenty-one consecutive patients were enrolled. A pathogen was identified in 78 (12.6%) patients. The most frequently isolated bacteria were S. pneumoniae (21.8%) and P. aeruginosa (19.2%). The clinical cure rate and length of stay were not different among patients treated with ß-lactam, ß-lactam and macrolide combination, and fluoroquinolone. Forty-seven patients (9.2%) died during the hospitalization period. There was no difference in survival among the three treatment groups. Conclusion: In patients admitted to non-ICU hospital wards for CAP, there was no difference in clinical outcomes between ß-lactam, ß-lactam and macrolide combination, and fluoroquinolone regimens.

The validity and reliability of the Turkish version of the Leicester Cough Questionnaire in COPD patients

Background/aim: The reliability and validity of the Turkish version of the Leicester Cough Questionnaire (LCQ) have been evaluated before. This study aimed to validate the Turkish version of the LCQ in chronic obstructive pulmonary disease (COPD) patients with cough. Materials and methods: COPD (GOLD B, C, D) patients over age 40 (n = 75) and healthy volunteers as a control group (n = 75) were included. A sociodemographic data form, the LCQ, the Short Form-36 (SF-36) quality of life questionnaire, and the World Health Organization Quality of Life Brief Form for Turkish people were completed. The internal reliability of the LCQ was determined using the Cronbach alpha coefficient (>0.6) and its repeatability by the intraclass consistency coefficient (P < 0.05) was accepted as significant. Results: For internal consistency, Cronbach alpha coefficients of all subscales of the LCQ, physical, psychological, and social, were found as 0.72, 0.86, and 0.83, respectively, with 0.92 for the total index. There was significant internal consistency for all subscales and the total index (Cronbach alpha coefficients of >0.6). In test­retest reliability, the correlation coefficient ranged between 0.71 and 0.80 for each question and was calculated as r = 0.89 for total LCQ score (P < 0.001). Conclusion: The Turkish version of the LCQ has been found to have acceptable reliability and validity for use in Turkish COPD patients with chronic cough.

Pneumococcal and influenza vaccination status of hospitalized adults with community acquired pneumonia and the effects of vaccination on clinical presentation.

BACKGROUND: Previous reports have shown that vaccination rates of adult at-risk populations are low in Turkey. There are differing reports with regards to the effectiveness of the influenza and the pneumococcal polysaccharide vaccine (PPSV23) on the clinical outcomes of community acquired pneumonia (CAP). The purpose of this study was to analyze the influenza (FV) and pneumococcal vaccination (PV) status, the factors that influence the receipt of influenza/pneumococcal vaccine and the effects of prior vaccination on the clinical outcomes in adults hospitalized with CAP. PATIENTS AND METHODS: Patients hospitalized with CAP between March 2009 and October 2013 and registered at the web-based Turkish Thoracic Society Pneumonia Database (TURCAP) were included in this multicentric, observational study. Of a total of 787 cases, data were analyzed for 466 patients for whom self-reported information on PV and FV was available. RESULTS: In this adult population with CAP, the vaccination rate with both the pneumococcal and influenza vaccines was found to be 6%. Prior FV was found to be the sole variable that was associated with the receipt of PV [OR 17.8, 95% CI (25-75:8.56-37.01), p < 0.001]. Conversely, being vaccinated with PPSV23 was the only predictor of receipt of FV [OR 18.1, 95% CI (25 - 75:8.75 - 37.83), p < 0.001]. Compared to the unvaccinated cases, the chest radiograms of the vaccinated patients revealed less consolidation. The latter also reported fatigue, muscle pain and gastrointestinal symptoms less frequently. Although there was a trend for lower 30-day mortality and for lower rates of intensive care unit (ICU) admission, these did not reach statistical significance. A pneumonia severity index (PSI) score ≥ 90, CURB-65 score ≥3 and multilobar involvement, but not the vaccination status, were identified as independent determinants of ICU admission. CONCLUSIONS: This study showed that, among patients hospitalized with CAP, the FV and/or PV rates are low. Prior vaccination does not appear to significantly affect the clinical outcomes.

[Evaluation of physians, patients, relatives and society of opinions on the told lung cancer diagnosis]. / Hekimlerin, hasta yakinlarinin ve toplumun akciger kanseri tanisinin söylenmesine iliskin görüslerinin degerlendirilmesi.

INTRODUCTION: In our country, this is usually done by patient relatives. In this study, we aimed to investigate the thought of doctors who done the diagnosis, doctors who arrange the treatment, first degree relatives of patients with lung cancer, and population as a control. MATERIALS AND METHODS: 310 subjects (100 doctors, 110 first degree realtives of patients, and 100 subjects as a control) were included to the study. The mean age was 39.77 ± 11.44 years and there was 170 females. 46% of doctors were giving cancer treatment (chemotheraphy/radiotheraphy). RESULT: 84.5% of subjects were answered the question (Do you want to know the diagnosis of lung cancer if you are lung cancer?) as "yes" and the answers were not different between groups (p> 0.05). 72 of doctors were giving information about diagnosis of patients. This ratio was 89.1% in doctors who arrange lung cancer treatment whereas it was 57.4% in doctors who do not arrange cancer treatment. The percent age of learning of diagnosis of lung cancer throughout the time in doctors, population, and patient's relatives were 19%, 34%, and 59% respectively (p< 0.05). Information about quality of life was more important in relatives of patients (87%) than population (65%) and doctors (63%) (p< 0.05). Quality of life was more important for doctors who arrange lung cancer treatment (76.7)% than doctors who did not (48.8%) (p< 0.05). Patients who were more children wanted to stay with their family at end stage of disease (p< 0.05). CONCLUSIONS: According to this study we think that doctors should say the diagnosis of lung cancer in the form of they understand, inform the patients and relatives about treatment, and quality of life and this can increase patient trust to doctor and compliance of patients to the treatment.

Serum procalcitonin and C-reactive protein kinetics as indicators of treatmentoutcome in hospitalized patients with community-acquired pneumonia.

BACKGROUND/AIM: There has been growing interest in the use of serum procalcitonin (PCT) and C-reactive protein (CRP) in patients with community-acquired pneumonia (CAP). The aim of this study was to investigate whether an assessment of fever, leukocyte count, and serum CRP and PCT levels on admission and during follow-up (day 3) provides any information about the clinical outcome in hospitalized patients with CAP. MATERIALS AND METHODS: Patients with a diagnosis of CAP who were admitted to and followed at four university hospitals were evaluated retrospectively using the Turkish Thoracic Society Pneumonia Database. RESULTS: A total of 103 hospitalized CAP patients (57 males, mean age: 61.5 ± 16.7 years) were enrolled in the study. Treatment failure (TF) was observed in 20 patients (19.4%). Pneumonia Severity Index scores, serum CRP levels, and PCT levels on admission were significantly higher in the TF group. There were significant decreases in CRP and PCT levels between admission day and day 3 in the treatment success group. CONCLUSION: In patients with CAP, the body temperature and leukocyte count on admission do not predict outcome. Monitoring levels of CRP and PCT may be useful as a predictor of treatment outcome.

Factors affecting treatment success in community-acquired pneumonia.

BACKGROUND/AIM: Treatment failure in hospitalized patients with community-acquired pneumonia is a major cause of mortality. The aim of this study was to evaluate the factors affecting treatment success in community-acquired pneumonia. MATERIALS AND METHODS: A total of 537 patients (mean age: 66.1 ± 15.8 years, 365 males) registered to the Turkish Thoracic Society Pneumonia Database were analyzed. Of these, clinical improvement or cure, defined as treatment success, was achieved in 477, whereas 60 patients had treatment failure and/or died. RESULTS: Lower numbers of neutrophils (5989.9 ± 6237.3 vs. 8495.6 ± 7279.5/mm3), higher blood urea levels (66.1 ± 42.1 vs. 51.2 ± 38.2 mg/dL), higher Pneumonia Severity Index (PSI) scores (123.3 ± 42.6 vs. 96.3 ± 32.9), higher CURB-65 scores (2.7 ± 1.2 vs. 2.2 ± 0.9), lower PaO2/FiO2 ratios (216.3 ± 86.8 vs. 269.9 ± 65.6), and the presence of multilobar (33.3% vs. 16.4%) and bilateral (41.7% vs. 18.9%) radiologic infiltrates were related to treatment failure. The PSI score and PaO2/FiO2 ratio were independent parameters affecting treatment results in multivariate linear regression analysis (P < 0.001). CONCLUSION: The risk of treatment failure is high in patients with severe pneumonia and with respiratory failure. Effective treatment and close monitoring are required for these cases.

Clinical characteristics and outcome of healthcare associated pneumonia in Turkey.

INTRODUCTION: Pneumonia in cases with preceding hospitalization, hemodialysis, intravenous therapy, wound care, or chemotherapy within the prior 30 days and residence in nursing homes are defined as healthcare associated pneumonia (HCAP). The aim of this study was to compare the demographic and laboratory data, isolated causative agents and prognosis of patients with community-acquired pneumonia (CAP) and HCAP in a large population in Turkey. MATERIALS AND METHODS: The data of 785 cases (average age 65.3 ± 16.4, 530 male) registered to Turkish Thoracic Society Respiratory Infections Study Group CAP database (TURCAP) were examined. The demographic data, clinical history, pneumonia severity scores (PSI), laboratory and radiologic findings of the CAP and HCAP patients were compared. RESULT: Out of 785 cases, 207 (26.4%) were diagnosed with HCAP and 578 (73.6%) with CAP. Among HCAP cases, 140/207 (67.6%) had preceding hospitalization in the last 90 days, 28/207 (13.5%) were on a hemodialysis program during the previous 30 days and 22/207 (10.6%) were staying in nursing homes. Patients with HCAP more frequently had comorbidities (93.2% vs. 81.6%; p= 0.001) and higher PSI scores (103.9 ± 37.2 vs. 94.6 ± 35.4; p= 0.002) compared to patients with CAP. A causative microorganism was isolated in only 12.1% (70/578) of CAP and 14.5% (30/207) of HCAP patients. The length of stay in hospital was higher in HCAP than CAP (8.6 ± 5.5 vs. 7.5 ± 6.1 days, p= 0.03); however the rates of treatment failure, intensive care unit admission and mortality were similar. CONCLUSIONS: In comparison to CAP, HCAP patients tend to have more severe disease, despite have no difference in mortality. The current criteria for HCAP do not predict worse clinical outcomes. Further work is required to define local risk factors for multidrug-resistant pathogens.

Metabolic syndrome and carotid intima-media thickness in chronic obstructive pulmonary disease.

BACKGROUND: The aim of this study is to investigate the prevalence of metabolic syndrome (MetS), carotid intima media thickness (IMT), and serum C-reactive protein (CRP) levels in patients with chronic obstructive pulmonary disease (COPD), and the possible relationships among them. METHODS: Fifty stable COPD patients and 40 healthy controls were included in the study. The participants were further divided into four groups according to their smoking status. Pulmonary function tests were performed in COPD patients. Anthropometric measurements and blood chemistry analysis, serum CRP levels and carotid intima-media thickness (IMT) measurements were performed in all the study population. RESULTS: Prevalence of metabolic syndrome was 43% in COPD patients and 30% in the control group (p = 0.173). FEV1% and FEV1/FVC were higher in COPD patients with MetS (p = 0.001 and p = 0.014, respectively) compared to those without MetS. Prevalence of MetS was significantly different among the COPD patients with different stages (p = 0.017) with the highest value in stage 2 (59%). Carotid IMT was significantly higher in COPD patients than in control group (1.07 ± 0.25 mm and 0.86 ± 0.18 mm, respectively; p < 0.001). Serum CRP levels were not different in COPD patients and controls, however they were higher in individuals with MetS compared to those without MetS regardless of COPD presence (p = 0.02). CONCLUSIONS: Early markers of atherogenesis, in terms of carotid IMT, were found to be higher in COPD patients than in healthy controls. MetS prevalence was observed to decrease as the severity of airflow obstruction increased. Therefore, screening COPD patients for these cardiovascular risk factors would be a novel approach even in absence of symptoms.

[A health survey in the workers of municipality]. / Belediye çalisanlarinda akciger sagligi taramasi

INTRODUCTION: Internal and external air pollution that is gradually increasing due to urbanization and industrialization has a negative impact on the lung health. A health survey has been applied to evaluate the respiratory symptoms, respiration functions and smoking habbits of the workers of Izmir Konak Municipality whom have been reported to have a high rate of smoking habbit and be affected by the external air pollution due to their being working in the field by the Municipality's doctor. MATERIALS AND METHODS: Questionnaire that are composed of the topics of work anamnesis, environmental anamnesis, curriculum vitae, symptoms (coughing, sputum, wheezing, dyspnea, hemoptysis) and smoking have been executed to 301 workers by face to face interview and their chest X-rays have been reviewed. RESULTS: Dyspnea on exertion, sputum in the morning, wheezing and morning cough have been the most frequently observed complaints (respectively 37.2%, 32.2%, 27.9% and 24.9%). Sanitary workers have reported sputum in the morning more while maintanance shop workers have reported wheezing more (p values respectively 0.009, 0.008). No significance has been observed while the workers are evaluated one by one regarding to their work groups. No significant difference was identified between the addiction of smoking and nicotin addiction or pulmonary function test and chest X-rays (p> 0.05) but active smoking was much more seen in drivers (p= 0.047). CONCLUSION: Although working on the hazardous work branch does not institute a sharp distinction, it becomes significant to trace and lead the workers in order to obtain their lung health protection in long term. Informing and influencing the workers about the harms of smoking and the ways to quit has been the most considerable acquisition of this survey.

Is the diagnosis of asthma different in elderly?

Asthma is mis-diagnosed, under-diagnosed and under-treated in older populations but has a high mortality rate. The physiological changes due to aging of lung, the co-morbid situations and poly pharmacy may change the typical presentation of asthma in older people and cause diagnostic difficulties. But it therefore should be diagnosed properly by taking of all differential situations especially chronic obstructive pulmonary disease into consideration since the appropriate management of the disease will alter the morbidity and mortality.

Clinical presentations and diagnostic work-up in sarcoidosis: a series of Turkish cases (clinics and diagnosis of sarcoidosis).

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 and pleural fluid N-Terminal-Pro-B-Type natriuretic peptide concentrations in the differential diagnosis of pleural effusions.

Currently, new biomarkers like N-Terminal-Pro-B-Type natriuretic peptide (NT-proBNP) have been used in the differential diagnosis of pleural effusions. In our study, we aimed to investigate the diagnostic value of NT-proBNP, especially in cardiac originated pleural effusions. Forty-five patients with pleural effusions were included in the study. NT-proBNP levels and biochemical markers involved in the Light's criteria were analyzed in pleural fluid and serums of the patients. Pleural fluid culture, AFB smear, cytology were performed where they were indicated according to the clinical evaluation. In patients, to whom cardiac pathology was considered to be; cardiological evaluation and echocardiography were also done. Thirty-eight pleural effusions were exudative and, 7 were transudative according to the Light's criteria. Final diagnosis were malignant effusion in 13, infection (tuberculosis/pneumonia) in 10, congestive heart failure in 21, and other conditions related with pleural effusion in 1 of the patients. Median (25th to 75th percentiles) NT-proBNP levels of serum and pleural fluid due to congestive heart failure (CHF) were 4747 pg/mL (931-15754) and 4827 pg/mL (1290-12.430) while median NT-proBNP levels of serum and pleural fluid related with non-cardiac reasons were 183 pg/mL (138-444) and 245 pg/mL (187-556) respectively. NT-proBNP levels of serum and pleural fluid were significantly high in CHF (p< 0.001 for both). When four groups were compared serum and pleural fluid NT-proBNP levels were highest in the CHF group which was followed by malignancy, infection and others (p< 0.001 for both). Fourteen of 21 patients who were accepted to have congestive heart failure as the final diagnosis by a cardiological evaluation had an exudative pleural fluid according to the Light's criteria. Serum and pleural fluid NT-proBNP levels were higher in transudates and this reached statistically significance for pleural fluid (p= 0.009). We suggest that measurement of pleural fluid NT-proBNP is a smart approach and pleural fluid NT-proBNP can reflect cardiac origin of effusions better than serum NT-proBNP and Light's criteria.

[Level of smoking of 3rd and 4th grade students studying health and related factors: follow-up study]. / Saglik egitimi alan 3 ve 4. sinif ögrencilerinde sigara kullanimi ve etkileyen faktörler: Izlem arastirmasi.

The levels of smoking of 1st and 2nd year students at Faculty of Medicine and Manisa School of Health at Celal Bayar University were investigated in 2006-2007. This study is carried out in order to see if there is a change in the same students' level of smoking while they are in 3rd and 4th year. In addition, the study aimed to examine the factors affecting the level of use and attitudes towards the law effectuated in July 19, 2009. This is a follow-up study with 80.42% return rate. A 26-item structured questionnaire was administered. The participants filled out the questionnaires under supervision of the researchers in their classrooms. The University Institutional Review Board approved the study. The total of participants (263) of the follow-up study included 189 female and 74 male. The rate of experimenting with smoking was 49% with the mean age of 15.7 (SD= 4.01 years). The mean age of experimenting with smoking was the earliest on male students studying at faculty of medicine. The level of smoking was found to be the most on females, studying at faculty of medicine and staying at the dormitory, with smoking parents (p< 0.05). The most important reason to begin smoking was curiosity (55.2%) while bad breath and yellowing of teeth were the reasons to quit (91.7%). 83.3% of the students thought that the law will be effective on quit smoking. The level of both experimenting and use of smoking has been increased over time. It is suggested that medical students' awareness about the danger of smoking should be raised at earlier grades. In addition, lectures should be offered to students at School of Health and they should be encouraged to unite in order to fight with smoking.

Occupational asthma in welders and painters.

We aimed to investigate the frequency of occupational asthma (OA) and the factors associated with OA development in a bicycle factory, subsequently after the diagnosis of OA in three workers at the same department. Forty one welders, 23 painters and 46 controls (office workers), a total number of 110 cases were included in the study. Turkish Thoracic Society Occupational and Environmental Diseases Evaluation Questionnaire and physical examination, chest-X ray, pulmonary function tests were performed as needed. Peak expiratory flow (PEF) follow-up was done in welders and painters. Cases having symptoms related with work and >or= 20% PEF variability were diagnosed as OA. Wheezing were more frequent in welders and painters than the control group, although there wasn't a statistical significance. Dyspnea, cough and sputum production were more frequent in welders and painters with respect to controls (p< 0.05). Nine (22%) welder, 4 (18%) painter were diagnosed as OA. Working duration of welders and painters with OA (72, 156 months, respectively) were longer than the welders and painters without OA (45, 76 months, respectively), but it did not have any statistically significance. We suggest that working in welding and painting departments may cause respiratory symptoms and OA.
