OBJECTIVE: This study aimed to evaluate the diagnostic value of the neutrophil-to-lymphocyte ratio (NLR) in early detection of metabolic syndrome (MetS) in patients with chronic obstructive pulmonary disease (COPD). PATIENTS AND METHODS:We retrospectively enrolled hospital records of 140 COPD patients and 50 sex and age-matched healthy controls. The diagnostic values of NLR were estimated using the sensitivity, specificity, and area under the receiver operating characteristic curve (AUC). RESULTS: In total, 140 patients with COPD of which 63 patients had MetS and 50 healthy subjects were included in the study. We found that the NLR values of the stable COPD patients were significantly higher than those of the controls (p < 0.001). Among patients with COPD, the NLR was significantly higher in patients with than without MetS (p < 0.001). The AUC of the NLR was 0.898 in patients with MetS.The optimal NLR cut-off was 2.56 and was validated in the testing set. For evaluation of MetS, the sensitivity and specificity were 84.1% and 84.4% in patients with COPD under the suggested cut-offs CONCLUSIONS: The NLR is a simple, effective, and practical predictor of MetS in patients with stable COPD. It has potential value in public health practice for management of patients with COPD. [ABSTRACT FROM AUTHOR]

OBJECTIVES: To demonstrate the pure effect of obstructive sleep apnea syndrome (OSAS) on cardiac autonomic function (CAF) using heart rate turbulence (HRT) parameters. PATIENTS AND METHODS: A total of 64 patients with OSAS and 30 age- and gender-matched healthy subjects were enrolled. All subjects had normal coronary arteries and were free from diabetes mellitus (DM) and hypertension (HT). The HRT parameters (TO, turbulence onset; TS, turbulence slope) were obtained from 24-h ambulatory electrocardiogram (ECG) recordings. HRT parameters were compared between groups, and the relationship between HRT and the apnea-hypopnea index (AHI) was examined. RESULTS: No between-group differences were found in age or gender. Mean TO was significantly higher in the OSAS group than in healthy controls (0.89 ± 0.5, -0.08 ± 0.26; p < 0.001; respectively). The mean TS did not differ between the two groups (2.81 ± 3.06 versus 3.14 ± 2.33; p = 0.212). The AHI was positively correlated with TO (r = 0.845, p < 0.001). The multiple logistic regression analysis revealed that after adjustment for other variables, TO was a significant and independent predictor of AHI, OR 2.394 (95% CI: 1.596-3.591). CONCLUSIONS: HRT (TO in particular) is correlated with AHI. Thus, impaired HRT may be an important factor underlying the occurrence of arrhythmia and sudden cardiac death in patients with OSAS.

Introduction: Sleep quality is known to be associated with the distressing symptoms of cancer. The purpose of this study was to analyze the impact of cancer symptoms on insomnia and the prevalence of sleep-related problems reported by the patients with lung cancer in Turkey., Materials and Methods: Assesment of Palliative Care in Lung Cancer in Turkey (ASPECT) study, a prospective multicenter study conducted in Turkey with the participation of 26 centers and included all patients with lung cancer, was re-evaluated in terms of sleep problems, insomnia and possible association with the cancer symptoms. Demographic characteristics of patients and information about disease were recorded for each patient by physicians via face-to-face interviews, and using hospital records. Patients who have difficulty initiating or maintaining sleep (DIMS) is associated with daytime sleepiness/fatigue were diagnosed as having insomnia. Daytime sleepiness, fatigue and lung cancer symptoms were recorded and graded using the Edmonton Symptom Assessment Scale., Result: Among 1245 cases, 48.4% reported DIMS, 60.8% reported daytime sleepiness and 82.1% reported fatigue. The prevalence of insomnia was 44.7%. Female gender, patients with stage 3-4 disease, patients with metastases, with comorbidities, and with weight loss > 5 kg had higher rates of insomnia. Also, patients with insomnia had significantly higher rates of pain, nausea, dyspnea, and anxiety. Multivariate logistic regression analysis showed that patients with moderate to severe pain and dyspnea and severe anxiety had 2-3 times higher rates of insomnia., Conclusions: In conclusion, our results showed a clear association between sleep disturbances and cancer symptoms. Because of that, adequate symptom control is essential to maintain sleep quality in patients with lung cancer.

Objective: To investigate the symptoms of lung cancer in Turkey and to evaluate approaches to alleviate these symptoms., Subjects and Methods: This study included 1,245 lung cancer patients from 26 centers in Turkey. Demographic characteristics as well as information regarding the disease and treatments were obtained from medical records and patient interviews. Symptoms were evaluated using the Edmonton Symptom Assessment Scale (ESAS) and were graded on a scale between 0 and 10 points. Data were compared using the χ2, Student t, and Mann-Whitney U tests. Potential predictors of symptoms were analyzed using logistic regression analysis., Results: The most common symptom was tiredness (n = 1,002; 82.1%), followed by dyspnea (n = 845; 69.3%), appetite loss (n = 801; 65.7%), pain (n = 798; 65.4%), drowsiness (n = 742; 60.8%), anxiety (n = 704; 57.7%), depression (n = 623; 51.1%), and nausea (n = 557; 45.5%). Of the 1,245 patients, 590 (48.4%) had difficulty in initiating or maintaining sleep. The symptoms were more severe in stages III and IV. Logistic regression analysis indicated a clear association between demographic characteristics and symptom distress, as well as between symptom distress (except nausea) and well-being. Overall, 804 (65.4%) patients used analgesics, 630 (51.5%) received treatment for dyspnea, 242 (19.8%) used enteral/parenteral nutrition, 132 (10.8%) used appetite stimulants, and 129 (10.6%) used anxiolytics/antidepressants. Of the 799 patients who received analgesics, 173 (21.7%) reported that their symptoms were under control, and also those on other various treatment modalities (dyspnea: 78/627 [12.4%], appetite stimulant: 25/132 [18.9%], and anxiolytics/antidepressants: 25/129 [19.4%]) reported that their symptoms were controlled., Conclusion: In this study, the symptoms progressed and became more severe in the advanced stages of lung cancer, and palliative treatment was insufficient in most of the patients in Turkey., (© 2016 S.

Water plays an important role in the transmission of Arcobacter spp. to animals and humans. The aim of this study was to isolate and characterize Arcobacter spp. from 115 different water samples (66 sewage, 25 rivers, 16 spring water, and 8 drinking water) in Izmir, Turkey. In total, 41 samples (35.7 %) were found positive for Arcobacter spp. by the genus-specific PCR. Arcobacter butzleri was detected in 39 out of 115 samples (33.9 %) including 24 sewage, 13 rivers, and 2 spring water. The remaining Arcobacter spp. (n = 2) isolates could not be identified by m-PCR and 16S rRNA gene sequencing. Based on the phenotypic characterization, most of the Arcobacter species (87.8 %) indicated weak catalase activity. In addition, there were differences in phenotypic patterns among isolated species during growth at 37 °C under microaerobic and aerobic conditions, in the presence of 2 % (39/41) and 3.5 % (32/41) NaCl and 0.04 % TTC (39/41) and on MacConkey agar (38/41). The results of this study indicated that environmental water samples are common sources for Arcobacter spp. Therefore, effective control measures should be taken to protect human health.

Chronic obstructive pulmonary disease (COPD) represents a systemic disorder characterized by chronic airflow limitation and an increased inflammatory response of the airways. Comorbidities are frequent in COPD and it is crucial to predict these in early stage for adequate management of COPD. Recent studies have reported that elevated levels of pregnancy-associated plasma protein-A (PAPP-A), a zinc-binding metalloproteinase, detected in patients with asthma, lung cancer, and pulmonary embolism and independently associated with cardiovascular events. We aimed to assess serum PAPP-A levels in COPD and the associations between disease severity. The study population consisted of 75 COPD patients and 35 healthy subjects as a control group. PAPP-A levels were measured by using ultrasensitive enzyme-linked immunosorbent assay. Elevated levels of PAPP-A were observed in patients with COPD on comparison with the controls (p = 0.000). The levels in stage 1 (34.73 ± 22.97) and stage 2 (48.29 ± 53.35) were significantly higher than stage 3 (20.58 ± 22.98) and stage 4 (27.36 ± 21.46) (p = 0.049). Increased PAPP-A levels may be a useful marker in management of COPD that seeks to prevent the development of comorbidities such as adverse cardiovascular diseases.

Background: Sarcoidosis is a multisystem disease, with extrathoracic involvement occurring in 25-50% of patients. Multi-organ involvement is often associated with a more chronic and severe course. The value of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in diagnosing extrathoracic involvement in sarcoidosis has been demonstrated; however, because of the radiation dose and high cost, indications for its use must be well defined. Angiotensin-converting enzyme (ACE) is produced by active granuloma cells; thus, serum ACE (sACE) levels may reflect the total granuloma load., Objectives: In this retrospective study, we evaluated the diagnostic value of sACE in the detection of extrathoracic involvement in sarcoidosis., Methods: 43 patients with biopsy-proven sarcoidosis underwent FDG-PET/CT during the initial workup. Positive findings were classified as thoracic and/or extrathoracic. The diagnostic value of sACE was estimated using sensitivity, specificity, and area under the receiver operating characteristic curves (AUCs)., Results: Of the 43 patients studied, 17 (39.7%) had extrathoracic involvement. In this group, sACE values were higher than in patients without extrathoracic involvement (331 vs. 150, p=0.002) and correlated positively with extrathoracic involvement (R:0.532 p=0.02). Receiver operator characteristic curve analysis revealed an AUC of 0.816 [95% confidence interval: 0.669-0.963, p=0.002], 70.6% sensitivity and 80% specificity at the sACE cut-off value., Conclusions: In sarcoidosis, extrathoracic involvement may be life threatening or indicative of poor outcome. sACE levels are easily determined and may predict extrathoracic involvement. In patients with sarcoidosis, sACE levels can be used to better define those who would benefit from FDG-PET/CT examination to detect extrathoracic involvement.

Introduction: Non-thyroidal illness syndrome (NTIS) is considered to be associated with adverse outcomes in intensive care unit (ICU) patients. In this study, we evaluated the association between NTIS and prolonged weaning in chronic obstructive pulmonary disease (COPD) patients admitted to the ICU., Materials and Methods: In total, 125 patients with COPD admitted to our ICU who underwent invasive mechanical ventilation (MV) were enrolled. We collected each patient's baseline characteristics including Acute Physiology and Chronic Health Evaluation (APACHE) II score, body mass index (BMI), and thyroid hormones 24 h after ICU admission. The presence of pulmonary infection was also recorded. The primary outcome was prolonged weaning, defined as patients who failed at least three weaning attempts or required > 7 days of weaning after the first spontaneous breathing trial., Results: Of the 127 patients studied, 64 had normal thyroid function tests and 61 had NTIS. Patients with NTIS had significantly higher APACHE II scores, prolonged weaning, and pulmonary infection. Patients with NTIS had a higher risk for prolonged weaning (odds ratio, OR = 3.21; 95% CI = 1.31-7.83).The presence of pulmonary infection was also an independent risk factors for prolonged weaning., Conclusions: NTIS may be an independent predictor for prolonged weaning in intubated COPD patients.

Chronic obstructive pulmonary disease (COPD) is a complex chronic inflammatory disease of the lungs in which inflammatory markers are involved with significant extrapulmonary effects that may contribute to its severity and complications. Moreover, some of the inflammatory markers such as C-reactive protein (CRP) are associated with COPD. Pentraxin 3 (PTX3) is the member of long pentraxins. The aim of the present study was to investigate the level of PTX3 in patients with COPD. Fifty-four COPD patients and 31 controls were enrolled in this study. Demographical data such as age, sex, cigarette smoking status, comorbidities, drugs, habits, and modified Medical Research Council (MMRC) dyspnea scores were recorded. All patients were asked for COPD Assessment Test™ (CAT). The mean age was 65.7 ± 9.8 years, 92 % male. Plasma levels of PTX3 were found to be markedly higher in COPD patients [1.65 (0.32-12.72) ng/ml] than in controls [1.05 (0.43-3.26) ng/ml; p = 0.005]. On the other hand, PTX3 values did not differ between COPD stages [A, 1.73 (0.69-11.03); B, 1.49 (0.84-12.52); C, 0.79 (0.52-1.06); and D, 2.09 (0.32-12.72); p = 0.27]. The plasma PTX3 levels were positively correlated with MMRC scores. We conclude that circulating PTX3 levels are elevated in COPD patients. Plasma levels of PTX3 were correlated with dyspnea (MMRC scores). But PTX3 levels were not correlated with the severity of COPD.

Fiberoptic bronchoscopy (FOB) is a procedure which has an important role in the diagnosis and treatment of lung diseases and is widely used in clinical practice. It is an invasive procedure and can cause cough, shortness of breath, nose and throat irritation. Stress during bronchoscopy can cause release of catecholamines, which may lead to tachycardia, vasoconstriction and possible myocardial ischemia in patients with impaired cardiopulmonary function. Current guidelines for bronchoscopy recommend offering sedation to patients, with the aim of improving patient comfort and reducing complications. For this purpose, the most frequently used sedatives are benzodiazepines, opioids, propofol and fospropofol which are either administered alone or in combination. In this review, we aimed to evaluate various drugs used for sedation during bronchoscopy.

This study aims to evaluate the incidence of non-thyroid illness syndrome (NTIS) among patients diagnosed as lung cancer and its association with the stage of the disease, Eastern Cooperative Oncology Group (ECOG) performance score, nutritional parameters, and survival. We enrolled 120 patients that 71 of them with newly diagnosed and staged non-small cell lung cancer and 49 of them small-cell lung cancer. The cases were examined for thyroid function tests, ECOG performance score, and nutritional evaluation before treatment. Also, cases were evaluated for their overall survival rates. NTIS was identified in 30 (42 %) of the 71 non-small cell lung cancer patients and 22 (44 %) of the 49 small-cell lung cancer patients. NTIS was more frequent among advanced stage of cases. Serum albumin level, cholesterol level, lymphocyte level, and body mass index were detected to be significantly low and ECOG performance score was significantly high in cases with NTIS when compared to cases without NTIS. NTIS was found to be negatively correlated with body mass index, ECOG performance score, and serum albumin level, and it was positively correlated with disease stage. NTIS was detected significantly as a poor prognostic factor for lung cancer. NTIS was frequently seen in cases with non-small cell lung cancer and small-cell lung cancer. NTIS can be used as a predictor of poor prognosis for lung cancer patients.

Background: Obstructive sleep apnea syndrome (OSAS) is associated with increased rates of cardiovascular diseases (CVD). The basic mechanisms involved in the increased cardiovascular risk of OSAS remain unclear. Recent discoveries of fat-secreted substances which serve endocrine roles improve our understanding of the relationship between OSAS, CVD, and the metabolic syndrome. In this study, we aimed to examine associations between omentin levels and OSA., Methods: Forty-six newly diagnosed OSA patients and 35 non-apneic controls were enrolled in this study. Demographical data, cigarette smoking status, previous history of chronic diseases including CVD and metabolic diseases and drugs, and habits were obtained using a standardized questionnaire. All patients underwent polysomnographic evaluation. Omentin was measured the following morning., Results: The mean age was 48.1 ± 12.5 (24-74) years in the OSA group and 42.8 ± 14.1 (21-69) years in the control group. Of the 81 patients, 46 (34 males and 12 females) were classified as having OSA and 35 patients (20 males and 15 females) as control. Plasma levels of omentin were found to be markedly higher in OSA patients (570.8 ng/ml) than in the control group (432.0 ng/ml; p < 0.001). In addition, plasma levels of omentin were found to be high in all OSA subgroups than in controls. The plasma omentin levels were significantly correlated only with age in patients with OSA., Conclusions: We conclude that circulating omentin levels are elevated in OSA patients. To the best of our knowledge, this is the first clinical study that demonstrated the association between omentin and OSA.

Objective: To investigate the diagnostic importance of mean platelet volume (MPV) on acute pulmonary embolism (APE) in the emergency Department (ED)., Methods: Subjects were selected from patients admitted to ED with clinically suspected APE. Demographic, anthropometric and serologic data were collected for each patient., Results: A total of 315 consecutive patients were analyzed, including 150 patients (53.44 ± 15.14 y; 92 men/58 women) in APE group and 165 patients (49.80 ±13.76y; 94 men/71 women) in the control group. MPV in the APE group was significantly higher than in the control group (9.42±1.22 fl vs. 8.04±0.89 fl, p<0.0001). The best cut-off values for MPV when predicting APE in patients with clinically suspected APE presenting at the ED were 8.55 fl (sensitivity 82.2%; specificity 52.3%)., Conclusions: MPV is a helpful parameter for the diagnosis of APE in ED, for the first time in the literature.

Aims: To determine the prevalence of asthma, asthma-like symptoms and allergic diseases among adults 30-49 years of age in regions of Bolu., Materials and Methods: A questionnaire was given to families of students in schools in different areas of Bolu, Turkey. The European Community Respiratory Health Survey (ECRHS) and a questionnaire, including questions about the socioeconomic status and demographic characteristics of the participants, were responded to by 1403 people., Results: The prevalence of symptoms and diseases were as follows: wheezing in the last year 12.0% (n=168), asthma 8.7% (n=121), doctor-diagnosed asthma 3.6% (n=50), currently taking drugs for asthma 1.2% (n=17), allergic rhinitis 16.5% (n=230), and eczema 9.6% (n=134). The risk factors for each symptom or disease were as follows: for wheezing: smoking in the house (odds ratio [OR]=2.43 and 95% Confidence Limits [95%CL]=1.53-3.86), living in a non-concrete building (OR=2.17, 95%CL=1.27-3.69); for asthma: mold in the house (OR=1.70, 95% CL=1.05-2.76), living in a shanty (OR=2.76, 95%CL=1.30-5.85), smoking in the house (OR=1.51, 95%CL=1.02-2.22); for allergic rhinitis: being female (OR=1.55, 95%CL=1.08-2.24), living in a shanty (OR=5.81, 95%CL=2.06-16.39), a monthly income below $300 (OR = 1.74, 95%CL=1.13-2.69)., Conclusions: A high rate of undiagnosed and untreated people with asthma among adults 30-49 years of age is present in Bolu. Especially, while a low socioeconomic level was observed to increase the risk of asthma and allergic rhinitis, risk of wheeze and asthma was found to be elevated by smoking in house.

Pulmonary nocardiosis is a subacute or chronic necrotizing pneumonia caused by aerobic actinomycetes of the genus Nocardia and rare in immune-competent patients. A 35-year-old male, who had treated with antituberculosis drugs, presented with cough, dyspnea, and expectoration with episodes of hemoptysis with purulent sputum. The diagnosis of nocardiosis was made by microscopic examination of the surgically resected portion of the lung and revealed filamentous Gram-positive bacteria.

Obstructive sleep apnea syndrome (OSAS) is associated with increased rates of cardiovascular diseases (CVD). Basic mechanisms involved in the increased cardiovascular risk of OSAS remain unclear. Inflammation has been shown to potentially play a critical role in this association. The aim of the present study was to investigate the level of cardiotrophin-1 (CT-1) in patients with OSAS. Forty-eight newly diagnosed OSAS patients and 37 nonapneic controls were enrolled in this study. Demographic data, cigarette smoking status, previous history of chronic diseases including CVD and metabolic diseases and drugs, and habits were obtained by a standardized questionnaire. All patients underwent polysomnographic evaluation. The mean age was 48.3 ± 12.3 (24-74) years in OSAS group. Median apnea-hypopnea index was 23.6 (6-91.8) and median body mass index was 30.4 (24.2-49.4) in the OSAS group. Plasma CT-1 levels in OSAS and control groups, respectively, were 12.03 ± 1.08 and 11.85 ± 1.18 pg/ml. There was no significant difference in the plasma levels of CT-1 and IL-6 between the OSAS group and the controls.

Background: The use of anti-TNF drugs for rheumatic diseases has increased in recent years. Several studies have reported an increased risk of reactivation of tuberculosis (TB) with anti-TNF agents., Objectives: The aim of this study was to present the follow-up results of a single center from Turkey, a country with a high rate of active and latent tuberculosis infection (LTBI), for INH chemoprophylaxis in patients receiving anti-TNF-α therapy for rheumatic diseases infection., Methods: In this prospective observational study, consenting patients who were to be administered an anti-TNF agent for a rheumatic disease were evaluated for the presence of active infection or LTBI by a chest X-ray and a tuberculin skin test. Patients with LTBI were given chemoprophylaxis 1 month prior to commencement of anti-TNF treatment. All patients were followed-up bimonthly for any signs of pulmonary or extrapulmonary TB., Results: A total of 73 patients, 23 female (31.5 %) and 50 male (68.5 %), with a mean age of 41.0 ± 13.1 years (18-78) were enrolled in the study. Overall, 44 patients (60.3 %) had ankylosing spondylitis, 18 (24.7 %) had rheumatoid arthritis, 7 (9.6 %) had juvenile rheumatoid arthritis, and 3 (4.1 %) had psoriatic arthritis. LTBI was identified in 58 patients all of whom received chemoprophylaxis for 9 months. None of the patients in the study developed any signs of tuberculosis reactivation during follow-up., Conclusions: TST is a reliable and cost-effective method for the diagnosis of LTBI in patients prior to anti-TNF therapy. Moreover, chemoprophylaxis with INH seems to be effective for the prevention of TB reactivation in individuals with LTBI.

Introduction: Plasma concentrations of circulatory markers of hemostatic activation which may be associated with tumor growth and dissemination have been shown to predict prognosis in malignancy. The present study was designed to investigate the prognostic value of plasma D-dimer level in lung cancer., Materials and Methods: Plasma levels of the D-dimer in 138 lung cancer patients [98 non-small cell lung cancer (NSCLC), 40 small cell lung cancer (SCLC)] were measured before the initiation of any therapy and each chemotherapy., Results: There were 124 (89.9%) men and 14 (10.1%) women with a mean age of 62.8 years (range 38-84). There were no statistically significant differences among the histopathologic types for NSCLC patients. Stage IIIA NSCLC group had statistically significant higher D-dimer level than stages I-II and IV. D-dimer levels were increased significantly after 4 cycles of chemotherapy in progressive disease. The median survival times in NSCLC patients were 26.6 months (95% CI, 17.6-35.6) and 15.9 months (95% CI, 4.2-27.7; p= 0.037) respectively, for patients with a low D-dimer level (≤ 1.2 ng/L) and a high D-dimer level (> 1.2 ng/L).With the cox-regression analysis, the plasma level of D-dimer and tumour stage were identified as independent predictive factors of the survival., Conclusion: These results suggest that plasmalevel of D-dimer can act as a predictive factor of decreased survival and a poor response to the treatment in lung cancer.

Bronchocentric granulomatosis is an uncommon entity which has no specific clinical, radiological and immunological features. It is usually diagnosed at morphological examination of biopsy or resected lung material. Aetiology of bronchocentric granulomatosis is unclear. A 49-year-old female patient, who was followed up with diagnosis rheumatoid arthritis in our outpatient clinic, presented with right lobe nodular lesion in chest radiography. Right thoracotomy and wedge resection was performed. Pathological examination revealed bronchocentric granulomatosis. Bronchocentric granulomatosis has been rarely reported in rheumatoid arthritis. This case might be a proof that bronchocentric granulomatosis may be one of the respiratory manifestations of rheumatoid arthritis.

Background: In chronic obstructive pulmonary disease (COPD) patients, functional and structural changes of the respiratory system greatly influence cardiovascular autonomic functions. Determining autonomic balance may be important in understanding the pathophysiology of COPD and useful clinically in the treatment of COPD patients. Heart rate variability (HRV) and heart rate turbulence (HRT) are useful tools in assessing the autonomic neurovegetative function. Our aim in this study was to evaluate the HRV and HRT variables in COPD patients. Twenty five moderate to severe COPD patients and 25 healthy subjects were included in this study., Methods: Pulmonary function tests and echocardiographic examination, arterial blood gases analysis were performed, HRV and HRT analysis were assessed from a 24-hour Holter recording., Results: When HRV and HRT parameters were compared, COPD patients had significantly decreased sNN50 total, pNN50, SDANN, SDNN, SDNNI, rMSDD in time domain HRV parameters, and the values of the HRT onset was significantly less negative in COPD patients. Although the values of the HRT slope were lower in COPD patients, there was no significant difference between the two groups. We also found a correlation between HRT and HRV parameters., Conclusions: In addition to HRV parameters, HRT onset was significantly different in COPD patients. In our opinion, the combination of HRV variables and HRT onset may be simple and elegant ways of evaluating cardiac autonomic functions. New investigations of HRT and HRV in COPD patients have a potential importance for improving risk stratification and therapeutic approaches, and understanding the autonomic outcomes of the disease process.

Chronic rhinosinusitis (CRS) is a common comorbidity of asthma. The aim of this study was to investigate the relationships between the presence of rhinosinusitis, sinus site involvement, and total computed tomography (CT) sinus scores and the presence of allergy, allergen type, and severity of disease. Asthma patients (128 subjects), consisting of 57 allergic and 71 nonallergic patients, were included in the study. Presence of rhinosinusitis and sinus scores were evaluated by CT. CRS was determined in 45 (78.9%) allergic asthma patients and 44 (62.0%) nonallergic asthma patients (p<0.05). Ethmoid sinus involvement was higher among allergic asthma patients compared with nonallergic patients (68.4% versus 43.7%; p=0.005). House-dust mite allergy (71.4% versus 46.5%; p=0.008) and pollen allergy (73.5% versus 47.9%; p=0.01) showed positive correlations with ethmoid sinus involvement. No correlation was found between severity of disease and mean total CT sinus scores (p>0.05). The present study has shown the prevalence of chronic sinusitis to be higher in patients with allergic asthma, particularly in patients allergic to house-dust mites and pollens, with no correlation between severity of disease and presence of CRS. Investigating chronic sinusitis together with allergen sensitivity early in asthma diagnosis may contribute positively to patient treatment.

Aim: In this study we aimed to detect the prevalence and risk factors of asthma and allergic diseases in children aged between 7 and 14 years old at rural and urban areas of Bolu, Turkey., Methods: Questionnaire of International Study of Asthma and Allergies in Childhood (ISAAC) phase one and questionnaire including questions about family, demographic, socio-economic characteristics of children were applied to 931 schoolchildren who were selected by randomized sampling., Results: In children, the prevalence of diseases and symptoms were as follows: wheeze ever: 15.5%, asthma: 5.6%, nasal symptoms ever: 41.4%, allergic rhinitis: 23.2%, itchy rash ever: 5.9% and eczema: 5.0%. In multivariate regression analysis, presence of allergic disease in the family was risk factor for wheezing (OR=1.74, 95% CI=1.19-2.76), asthma (OR=2.19, CI=1.06-4.52), allergic rhinitis (OR=2.68, CI=1.80-3.98) and eczema (OR=2.33, CI=1.17-4.65); living in shanties was risk factor for allergic rhinitis (OR=5.26, CI=2.1-13.16); a monthly income below $300 was risk factor for asthma (OR=2.54, CI=1.06-6.08)., Conclusion: It was detected that the prevalence of allergic rhinitis and its symptoms was more common in schoolchildren living in Bolu. Presence of allergic disease in fathers or mothers and low socio-economic level increase the risk of asthma and other allergic diseases in children.

Objective: The aim of this study was to determine the influence of smoking habits and education of family, parents, the type of school and gender on smoking in adolescents., Methods: This cross-sectional study was performed on 1062 students from eight high schools in Eyup, Istanbul., Results: Twenty-five per cent of students were current smokers (30.1% of boys [n = 551], 20.9% girls [n= 511] 95% CI [26%, 34%] and [17%, 24%] respectively, (p < 0.05). Smoking rate was highest in vocational high schools and lowest in super high schools (33% [n = 406, 95% CI (29%, 38%)] and 11% [n = 127, 95% CI (6%, 17%)] respectively, p < 0.05). Smoking rate was higher in mothers (31.6% [n = 174, 95% CI (25%, 39%)] vs 15.5% [n = 336, 95% CI(12%, 19%)] and siblings (27.7% [n = 141, 95% CI (20%, 35%)] vs 18% [n = 350, 95% CI (14%, 22%)] of the female students who smoke than of those who did not smoke (p < 0.05). The rate of smoking in the siblings of 'smoker' boys was higher than that of 'non-smoker' boys (44.6% [n = 130, 95% CI (36%, 53%)] and 26.1% [n = 402, 95% CI (22%, 30%)] respectively; p < 0.05). The education level of 28%, [n = 82, 95% CI (19%, 39%)] of the mothers of 'smoker' girls, and of 19.6% [n = 429, 95% CI (16%, 23%)] of 'non-smoker' girls was high school and above (p < 0.05). The rate of high school and above education was higher in parents of male students who smoke than that in nonsmokers [45.1% and 27.9%, 95% CI (33%, 55%)] and (24%, 32%), respectively, p < 0.05. Number of smokers saying "Yes" in support of controlling smoking was less than non-smokers (p < 0.05)., Conclusion: Smoking rate was higher in boys, in vocational high schools and seems to be influenced by smoking habits and higher educational levels of their family members. This influence differs according to gender. Anti-tobacco messages should target family, friends and schools of adolescents.

In this study we aimed to determine the smoking habits of the elementary school teacher students and to examine the factors affecting smoking. The prepared questionnaires were applied to 3rd and 4th year students by selecting randomly. The ratio of the students smoking regularly and occasionally was 45.8%. The smoking frequency was higher in male and fourth year students [63 (53.8%) of males, 85 (41.3%) of females (p< 0.05); 102 (52.3%) students in 4th year and 46 (35.9%) students in 3rd year (p< 0.01)]. The most common reason of not smoking was the harmful effect of smoking to life (45.8%), the most common reason of initiating smoking was to decrease their stress (43.1%) and the most common reason to keep on smoking was difficulty of quitting (56.7%). When compared to nonsmokers, the smoking frequency of mothers, brothers, all family members and close friends of smoker students were higher (p< 0.05). There was significant difference between depression symptom scores of the students who were smoking and the ones who were nonsmokers (14.9 +/- 7.6 in smokers, 9.8 +/- 6.3 in nonsmokers; p< 0.05). The smoking frequency among school teacher students was very high. The smoking habits of close friends, regular alcohol intake, and presence of depressive symptoms were increasing the risk of smoking. It will be beneficial for public health to plan and apply appropriate education program for students who will be the first teachers of the primary school students, not to start smoking.

We aimed to evaluate the treatment outcome of pulmonary tuberculosis patients and factors affecting treatment outcomes. We analyzed the records of 586 pulmonary tuberculosis patients who were older than 15 years followed between January 1999 and December 2004. Of these patients, 76.1% were smear-positive for tuberculosis and 23.9% were smear-negative for tuberculosis. The treatment outcomes of all patients analyzed were as follows: treatment success 91.7%, defaulted treatment 5.1%, died 2.4%, failure 0.3%, and transferred out 0.5%. The treatment outcomes of smear-positive pulmonary tuberculosis patients were as follows: cured 77.1%, treatment completed 13.5%, defaulted treatment 5.4%, died 2.9%, failure 0.4%, and transferred out 0.7%. In multivariate regression analysis, risk factors for non-successful treatment outcome were determined to be re-treatment patients, patients older than 46 years of age, and the presence of rifampicin resistance. We conclude that application of Directly Observed Therapy may increase treatment success in all patients, especially patients who have risk factors for a low treatment success rate.

Several statins inhibit T-helper 1 development and induce T-helper 2 polarization and production of T-helper 2 cytokines that promote the activation and chemotaxis of eosinophils. Whether statins promote the development of nasal polyps has so far been uncertain. No studies have evaluated the frequency of the development of nasal polyps in patients using statins. To better define the relationship of statin use to the presence of nasal polyps, the investigators explored the frequency of the development of nasal polyps in patients who were using statins. A total of 200 patients who were using statins and 200 who were not using statins (400 cases) were investigated. All patients were examined for nasal polyps by anterior rhinoscopy or investigation with a fiberoptic endoscope. In addition, immunoglobulin E levels were measured, a skin prick test was performed, and the results from the 2 groups were compared. Nasal polyps were detected in 4 subjects who were using statins, whereas 5 nasal polyps were found in the control group; differences between the 2 groups were statistically insignificant (P>.05). When the atopy status of the 2 groups was compared, prick test positivity and serum immunoglobulin E levels were found to be 15% and 44+/-31 IU/mL in the statin group and 19% and 68+/-23 IU/mL in the control group (P>.05). These results show that nasal polyposis is a multifactorial disease with several different causes; however, the frequency of the development of nasal polyps does not increase in patients who use statins.

Background and Objective: The effect of inhaled budesonide on oropharyngeal Gram-negative bacilli colonization (OGNBC) in asthmatic patients was investigated., Methods: Oropharyngeal cultures were obtained from asthmatic patients attending the hospital respiratory outpatient clinic, at baseline and 1 month after treatment with 800 microg/day of inhaled budesonide. Cultures were evaluated for OGNBC and compared with those of healthy controls., Results: A total of 148 cultures (74 from asthma patients, 74 from healthy controls) were evaluated. Six cultures (8.1%) from healthy controls, eight cultures (10.8%) from asthma patients obtained before treatment and 20 cultures (27.0%) obtained after treatment were positive for OGNBC (P < 0.05). Gender, age, presence of atopy and the degree of illness were not found to be related to the presence of OGNBC in and healthy control cultures. In the cultures obtained from the patients after treatment, OGNBC was higher in patients >50 years and in those with FEV1 < 70% (P < 0.05). Nine (18.8%) of 48 patients <50 years compare with 11 (42.3%) of the 26 patients >50 revealed OGNBC (P < 0.05). OGNBC were observed in 18.9% of the patients with FEV1 = 70% and in 47.6% of those with FEV1 < 70% (P < 0.05)., Conclusions: The increased rate of OGNBC in asthma patients treated with inhaled budesonide was found to be related to increased age and lower level of FEV1. Further studies with larger numbers of patients are required for the interpretation of this colonization in the course of lower respiratory infections in these patients.

We aimed to determine the smoking habits of the health care workers and their approach to smoking. A questionnaire was applied to the health care workers about smoking in the counties of Istanbul (in Eyüp and Gaziosmanpaşa). Of 629 participants, the ratio of smoking in all health care workers was 49.3%. There was no difference in the frequency of smoking in the health care workers about sex, marital status, private or state hospital, the group of job, general practitioner or specialist doctor (p> 0.05). However, the rate of smoking was lower in married doctors than unmarried ones, and it was higher in male technician than females (p< 0.05). Partners of smoker doctors and nurses had higher smoking rate (p< 0.01). There was no difference between smoker and nonsmoker doctors in asking about smoking to their patients. The rate of "Yes" answer to the question of "Do you explain the necessity and recommend to give up smoking to more than 70% of your smoking patients?" asked to the doctors was different between smoker and nonsmoker doctors (58.8% and 72.5% respectively, p< 0.05). These results show that more efforts are needed and should be spent on the education about the harmful effects of tobacco products and needs of fighting against smoking in medical faculties, in health occupation schools, in all health care services.

Obstructive sleep apnea (OSA) is a common medical condition that occurs in approximately 5% to 15% of the population. It is usually associated with an increased risk of cardiovascular disease. Diagnosis of OSA is based on polysomnography, and its severity is measured with an apnea-hypopnea index. Most of the adverse effects of OSA on the cardiovascular system are reversible with treatment. In addition to continous positive airway pressure therapy, precautions such as weight loss, avoidance of central nervous system depressants, treatment of nasal congestion and sleeping in the lateral position may help to treat OSA. (Cardiol J 2007; 14: 534-537).

Background: In this study we aimed to investigate the effect of triamcinolone acetonide aqueous (TAA) intranasal spray that was used for 2 months to treat allergic rhinitis (AR) on the nasal carriage of Staphylococcus aureus (NCSA)., Methods: A total of 125 adult AR patients (study group) and 133 healthy individuals (control group) were enrolled for the study. The subjects were diagnosed with AR after a detailed history, physical examination, and prick testing. The AR subjects were administered TAA in a daily dosage of a 220-microg intranasal route. Nasal cultures were obtained on the 1st (baseline), 55th, and 60th days, and the subjects in the last two cultures of whom S. aureus was detected were accepted as NCSA., Results: After all exclusion criteria were used, 110 AR and 114 control group subjects were enrolled in the study. Based on the culture results that were obtained on the 55th and 60th days, 10 (%9.1) patients from the study group and 18 (%15.7) individuals from the control group were defined to be NCSA (p > 0.05)., Conclusion: We conclude that the use of TAA treatment for AR does not increase the prevalence of NCSA. However, additional studies with a larger series are required to explain the effects of steroids on nasal colonization of S. aureus.

Objective: Oxidative stress plays an important role in the pathogenesis of asthma. Recent data suggest that clinical indices of the patients with asthma may not correlate with the underlying inflammatory process. We aimed to measure the level of malondialdehyde (MDA), which is a marker of lipid peroxidation, a free radical-mediated process, before and after a well-accepted treatment of asthma., Methodology: Nine non-smoking females and five non-smoking males with mild-moderate asthma were included. Twenty-four age- and sex-matched, non-smoking healthy people (17 females and seven males, mean age 32.1 years, range 20-59) were included for control. After initial evaluation, spirometry, bronchoscopy with bronchoalveolar lavage (BAL), and blood sample were maintained. The patients were treated with twice-daily salmeterol inhaler (100 microg/d) and fluticasone propionate inhaler (500 microg/d). One month later the investigations were repeated. Serum MDA levels before treatment were compared with both the levels after treatment and levels of controls. Malondialdehyde levels of BAL were compared before and after treatment., Results: Serum MDA level of the patient before treatment was 6.7+/-0.8 nmol/mL, significantly higher than that of healthy controls; 3.8+/-0.4, P < 0.001. One month after the treatment, serum MDA level decreased to 5.3+/-0.7 nmol/mL (P < 0.001). However, this level is still significantly higher than healthy controls (P < 0.0001). Forced expiratory volume in 1 s level of the patients increased from 2.43+/-0.79 L to 3.50+/-1.21 L after the treatment (P < 0.001)., Conclusion: Although treatment with beta2-agonist and corticosteroid inhalers for the duration of 1 month reduced lipid peroxidation significantly, it was still at a level significantly higher than healthy controls. The treatment may need a longer duration to improve lipid peroxidation or an alternative regimen which is more effective in controlling inflammation may be warranted.
