RESUMO
INTRODUCTION: Quick and simple parameters are needed to predict mortality in patients with idiopathic pulmonary fibrosis (IPF). In this way, risky patients will have the opportunity to receive early and effective treatment. In this study, we examined whether the Fibrosis-4 index (FIB-4) and systemic immune inflammation index (SII) are associated with mortality in IPF patients. MATERIALS AND METHODS: The study was designed retrospectively. 100 patients diagnosed with IPF were included in the study. Variables between living patients and deceased patients were examined. RESULTS: Out of a total of 100 patients, 67 were divided into the surviving group and 33 into the non-surviving group. In multivariate analysis, high FIB-4 and SII values were significantly associated with an increased risk of death. CONCLUSION: FIB-4 and SII are parameters that can predict mortality in IPF patients. In this way, IPF patients with high mortality risk will be identified earlier and more effective methods will be used in follow-up and treatment.
RESUMO
Pulmonology is one of the branches that frequently receive consultation requests from the emergency department. Pulmonology consultation (PC) is requested from almost all clinical branches due to the diagnosis and treatment of any respiratory condition, preoperative evaluation, or postoperative pulmonary problems. The aim of our study was to describe the profile of the pulmonology consultations received from emergency departments in Turkiye. A total of 32 centers from Turkiye (the PuPCEST Study Group) were included to the study. The demographic, clinical, laboratory and radiological data of the consulted cases were examined. The final result of the consultation and the justification of the consultation by the consulting pulmonologist were recorded. We identified 1712 patients, 64% of which applied to the emergency department by themselves and 41.4% were women. Eighty-five percent of the patients had a previously diagnosed disease. Dyspnea was the reason for consultation in 34.7% of the cases. The leading radiological finding was consolidation (13%). Exacerbation of preexisting lung disease was present in 39% of patients. The most commonly established diagnoses by pulmonologists were chronic obstructive pulmonary disease (19%) and pneumonia (12%). While 35% of the patients were discharged, 35% were interned into the chest diseases ward. The majority of patients were hospitalized and treated conservatively. It may be suggested that most of the applications would be evaluated in the pulmonology outpatient clinic which may result in a decrease in emergency department visits/consultations. Thus, improvements in the reorganization of the pulmonology outpatient clinics and follow-up visits may positively contribute emergency admission rates.

BACKGROUND: Our aim is to determine the caregiver burden of chronic obstructive lung disease (COPD) patient's caregivers, and to determine whether there is a workday loss. METHODS: 252 COPD patients and their caregivers were included. Disease information of the patients were recorded and a questionnaire was applied. Socio-demographic characteristics of the caregivers were recorded and a questionnaire consisting of 24 questions including COPD disease, treatment and loss of working days, and the Zarit Scale were used. RESULTS: 128(50.8%) of the patients according to GOLD were group-D, 97(38.5%) of the patient's relatives were working, 62(24.7%) were not able to go to work for 1-14 days, and 125(57.1%) spent outside the home from 1-14 nights, because those accompanied to patients. In univariate analysis were detected modified medical research council (mMRC) (p < 0.001), CAT (p < 0.001), the number of comorbidities of patients (p = 0.027), forced expiratory volume in 1 FEV1cc (p = 0.009), FEV1% (p < 0.001), the presence of long term oxygen therapy (LTOT), and the number of comorbidities of the patient's relatives (p = 0.06) increased the care load. In multiple linear regression analysis, age (p = 0.03), COPD assessment test (CAT) score (p = 0.001), FEV1% (<0.068) and the number of comorbidities of patients (p = 0.01) and the number of comorbidities of caregivers (p = 0.003) increased the caregiving burden. DISCUSSION: In COPD increases caregiving burden. This burden is greater in symptomatic patients and when comorbidities are present. Psychosocial and legal regulations should be investigated and solutions should be produced for the caregivers of COPD patients.

Introduction: The aim of our study is to investigate the etiological distribution of ILD in Turkey by stratifying the epidemiological characteristics of ILD cases, and the direct cost of initial diagnosis of the diagnosed patients. Material-Method: The study was conducted as a multicenter, prospective, cross-sectional, clinical observation study. Patients over the age of 18 and who accepted to participate to the study were included and evaluated as considered to be ILD. The findings of diagnosis, examination and treatment carried out by the centers in accordance with routine diagnostic procedures were recorded observationally. Results: In total,1070 patients were included in this study. 567 (53%) of the patients were male and 503 (47%) were female. The most frequently diagnosed disease was IPF (30.5%). Dyspnea (75.9%) was the highest incidence among the presenting symptoms. Physical examination found bibasilar inspiratory crackles in 56.2 % and radiological findings included reticular opacities and interlobular septal thickenings in 55.9 % of the cases. It was observed that clinical and radiological findings were used most frequently (74.9%) as a diagnostic tool. While the most common treatment approaches were the use of systemic steroids and antifibrotic drugs with a rate of 30.7% and 85.6%, respectively. The total median cost from the patient's admission to diagnosis was 540 Turkish Lira. Conclusion: We believe that our findings compared with data from other countries will be useful in showing the current situation of ILD in our country to discuss this problem and making plans for a solution.
RESUMO
INTRODUCTION: The results of standard chemotherapy in lung cancer are not very satisfactory, so it is important to identify genetic mutations that provide targeted therapies. Recent reports have suggested influences of racial difference on the frequency of mutation in lung cancer. We aimed to determine the frequency and regional distribution of genetic mutations of non-small cell lung cancer (NSCLC) in Turkey. MATERIALS AND METHODS: Regional distribution of genetic mutations in lung cancer in Turkey (REDIGMA) study was carried out as a prospective, cross-sectional, observational study in a large number of centers in which lung cancer patients were followed and could perform genetic mutation analysis on patients' biopsy materials. RESULT: The 703 patients (77.7% male, mean age 63.3 ± 12.5 years) who were diagnosed as NSCLC from 25 different centers were included in the study. Tumor samples from patients were reported as 87.1% adenocarcinoma, 6.4% squamous cell carcinoma and 6.5% other. Mutation tests were found to be positive in 18.9% of these patients. The mutations were 69.9% EGFR, 26.3% ALK, 1.6% ROS and 2.2% PDL. Mutations were higher in women and non-smokers (p<0.000, p<0.001). Again, the frequency of mutations in adenocarcinoma was higher in metastatic disease. There was no difference between the patient's age, area of residence, comorbidity and clinical stage and mutation frequency. CONCLUSIONS: Our study revealed that the EGFR mutation rate in Turkey with NSCLC was similar to East European, African-American and Caucasian patients, and was lower than in East Asia.

Neurogenic inflammation plays a role in the pathophysiology of allergic rhinitis. Highly effective in reducing the sensory irritation caused by some substances, strontium salts directly affect C-type nerve fibers. The aim of this study was to compare the efficacy of mometasone furoate and strontium chloride on early-phase symptoms in a rat model of allergic rhinitis. Wistar albino rats (n = 24) were randomly divided into three groups: the mometasone group, receiving 1 µg mometasone furoate (2 µl/site); the strontium 3% group, receiving 3% strontium chloride (2 µl/site); and the strontium 5% group, receiving 5% strontium chloride (2 µl/site). To induce significant nasal symptoms of allergic rhinitis, 5 µmol of histamine dihydrochloride (HDC) (2 µl/site) was administered. Symptoms of allergic rhinitis were recorded as frequencies of sneezing and nasal rubbing during a 15-minute interval. On days 1 and 2, respectively, 0.9% sodium chloride (NaCl) (2 µl/site to each nasal cavity) and HDC were administered in all of the study groups. On days 3 and 4, the study drugs were administered 10 and 30 minutes before the administration of HDC. On day 5, the study drugs were administered 10 minutes after the administration of HDC. The results of the present study revealed that when strontium chloride or mometasone furoate was administered 30 minutes before the onset of symptoms, a significant decrease was observed in sneezing and nasal rubbing. The number of sneezing occurrences was significantly lower and the number of nasal rubbing occurrences was higher in the strontium 3% group compared to the groups in which mometasone furoate and 5% strontium chloride were administered after onset of symptoms. Recent studies have investigated the efficacy and safety of strontium chloride nasal drops compared with common pharmacologic treatments of allergic rhinitis. These studies have revealed that allergic rhinitis can be successfully and safely treated with strontium-chloride-containing products, thus offering a potential new treatment strategy.

OBJECTIVE: The aim of the present study was to examine the relationship between the results of the transient otoacoustic emission (TEOAE) test used in neonatal hearing screening and the results of the umbilical cord blood (UCB) analysis in neonates. METHODS: This retrospective study included 209 neonates born in the obstetric unit at the 37th gestational week. Based on the results of the TEOAE test, the neonates included in the study were divided into two groups as the study group composed of those "REFER" (n=141) and the control group consisting those "PASS" (n=68) the test. The UCB sampling procedure was performed on all neonates. In the blood samples, the pH parameters were evaluated by using glass electrodes, and the pCO2 and pO2 parameters were evaluated directly by using sensitive electrodes. RESULTS: When the additional maternal diseases were compared with the TEOAE results, the ratio of hypothyroidism was found to be statistically higher in the study group (p<0.05). In terms of the pO2, pCO2, HCO3, and pH values obtained as a result of analyzing the UCB samples, there was no statistically significant difference between the groups (p>0.05). CONCLUSION: The results of the present study showed that there was no statistically significant difference between the results of UCB analysis and the TEOAE test. However, we believe that conducting a larger study evaluating other parameters and employing UCB analysis would be useful, and UCB evaluation, which is an inexpensive, easy and effective method in determining hypoxia in neonates, might be a significant marker in cases at risk of hearing loss.
RESUMO
OBJECTIVE: Mutations in the p53 gene are the most commonly observed genetic abnormalities in malignancies. The purpose of this study was to assess the diagnostic value of serum anti-p53 antibody (Ab) along with the correlation between serum anti-p53 Ab level and quantitative positron emission tomography (PET) parameters such as maximum standardized uptake value (SUVmax), SUVave, metabolic tumor volume, total lesion glycolysis (TLG) and tumor size. METHODS: Serum anti-p53 Ab level was studied in three groups. Patients who underwent 18F-fluorodeoxyglucose (FDG) PET/computed tomography (CT) imaging for staging of previously diagnosed lung cancer constituted the first group, while patients who underwent 18F-FDG PET/CT imaging for evaluation of suspicious pulmonary nodules detected on thorax CT and did not show pathologic FDG accumulation (NAPN=pulmonary nodule with non avid-FDG) were enrolled in the second group. The third group consisted of healthy volunteers. RESULTS: Twenty-eight patients with lung cancer (median age: 62.5, range: 39-77years), 28 patients with NAPN (median age: 65, range: 33-79 years), and 24 healthy volunteers (median age: 62, range: 44-74 years) were enrolled in the study. The serum anti-p53 Ab level was low in healthy volunteers while it was higher in both lung cancer patients and NAPN patients (p<0.05). When serum anti-p53 Ab level and PET parameters were evaluated, there was no significant correlation between serum anti-p53 Ab level and SUVmax, SUVave, TLG, tumor volume and tumor size of patients with lung cancer (p>0.05). Besides, there was no significant difference between serum anti-p53 Ab level and lesion size of NAPN patients (p>0.05). CONCLUSION: It was determined that serum anti-p53 Ab levels are not significantly correlated with PET parameters, and that serum anti-p53 Ab levels increase in any benign or malignant lung parenchyma pathology as compared to healthy volunteers. These results indicate that this Ab cannot be used as a predictor of malignancy in a lung lesion.
RESUMO
BACKGROUND: Cancer antigen-125 (CA-125) might be a useful biomarker to predict long-term mortality in patients with recent exacerbation of chronic obstructive pulmonary disease (COPD). METHODS: A total of 87 consecutive patients with COPD were evaluated prospectively. Mean age of patients was 68 ± 10 years (55% males, 45% females) with a median follow-up period of 49 months. Optimal cut-off value of CA-125 to predict mortality was found as >93.34 U/ml, with 91% specificity and 40% sensitivity. RESULTS: After follow-up, 20 out of 87 (23%) experienced cardiovascular death. CA-125 levels were higher among those who died compared to those who survived [55 (12-264) versus 28 (5-245) U/ml, p = 0.013]. In multivariate Cox proportional-hazards model with forward stepwise method, only CA-125 > 93.34 U/ml on admission (HR = 3.713, 95% CI: 1.035-13.323, p = 0.044) remained associated with an increased risk of death. CONCLUSIONS: For the first time, we demonstrated that CA-125 helps the risk stratification of patients with COPD.

BACKGROUND: Obstructive sleep apnea (OSA) is a major disease that can cause significant mortality and morbidity. Chronic intermittent hypoxia is a potential causal factor in the progression from fatty liver to nonalcoholic steatohepatitis. OBJECTIVES: This study evaluated the association between the degree of liver steatosis and severity of nocturnal hypoxia. PATIENTS AND METHODS: In this study, between December 2011 and December 2013, patients with ultrasound-diagnosed NAFLD evaluated by standart polysomnography were subsequentally recorded. Patients with alcohol use, viral hepatitis and other chronic liver diseases were excluded. We analyzed polysomnographic parameters, steatosis level and severity of obstructive sleep apnea (OSA) in consideration of body mass index (BMI), biochemical tests and ultrasonographic liver data of 137 subjects. Patients with sleep apnea and AHI scores of < 5, 5 - 14, 15 - 29 and ≥30 are categorized as control, mild, moderate and severe, respectively. RESULTS: One hundred and thirty-seven patients (76 women, 61 men) with a mean age of 55.75 ± 10.13 years who underwent polysomnography were included in the study. Of 118 patients diagnosed with OSA, 19 (16.1%) had mild OSA, 39 (33.1%) moderate OSA and 60 (50.8%) severe OSA. Nineteen cases formed the control group. Apnea/hypopnea index and oxygen desaturation index (ODI) values were significantly higher in moderate and severe non-alcoholic fatty liver disease (NAFLD) compared to the non-NAFLD group. Mean nocturnal SpO2 values were significantly lower in mild NAFLD and severe NAFLD compared to the non-NAFLD group. Lowest O2 saturation (LaSO2) was found low in mild, moderate and severe NAFLD compared to the non-NAFLD group in a statistically significant manner. CONCLUSIONS: We assessed polysomnographic parameters of AHI, ODI, LaSO2 and mean nocturnal SpO2 levels, which are especially important in the association between NAFLD and OSAS. We think that it is necessary to be attentive regarding NAFLD development and progression in patients with OSA whose nocturnal hypoxia is severe.
RESUMO
One of the most significant diseases related to environmental asbestos exposure is malignant mesothelioma (MM). Sivas province is located in the Central Anatolia where asbestos exposure is common. We aimed to study clinical, demographical and epidemiologic features of the patients with MM in Sivas, along with the history of asbestos exposure. In total, 219 patients with MM who were diagnosed in our hospital between 1993 and 2010 were retrospectively analyzed in terms of demographical and clinical features. Rock, soil and house plaster samples were taken from the habitats of those patients and were evaluated with optical microscopy and X-ray diffraction methods. The age of the patients ranged between 18 and 85 years. The male-to-female ratio was 1.4:1. Most of the patients confirmed an asbestos exposure history. The most frequent symptoms of the patients were chest pain (60 %) and dyspnea (50 %). The gap between the start of first symptoms and the diagnosis date was approximately 4 months in average. The plaster materials used in most of the houses were made up of mainly carbonate and silicate minerals and some chrysotile. Ophiolitic units contained fibrous minerals such as serpentine (clino + orthochrysotile) chiefly and pectolite, brucite, hydrotalcite and tremolite/actinolite in smaller amounts. MM is not primarily related to occupational asbestos exposure in our region, and hence, environmental asbestos exposure may be indicted. Yet, single or combined roles and/or interactions of other fibrous and non-fibrous minerals in the etiology of MM are not yet fully understood and remain to be investigated.

BACKGROUND: The role of biomarkers for prognostication and diagnosis of pulmonary embolism (PE) is increasing. It has been reported that pregnancy-associated plasma protein-A (PAPP-A) can be used as a proatherosclerotic marker. The present study was aimed to evaluate whether PAPP-A levels are helpful in the differential diagnosis of patients presenting with suspected PE. METHODS: 53 consecutive patients evaluated for suspected PE were prospectively enrolled in the study. Serum PAPP-A levels were measured in the blood samples which were taken at admission. Multi-slice computed tomographic angiography was used to verify the diagnosis of PE. RESULTS: PE was detected in 24 out of the 53 patients, while it was excluded in 29 patients by thorax multi-detector computerized tomography scan. No significant difference was detected in mean serum PAPP-A level between groups (5.72 ± 0.31 mg/L vs. 5.67 ± 0.06 mg/L, respectively). CONCLUSIONS: Serum PAPP-A level has no role in the evaluation for PE.
RESUMO
BACKGROUND: Both obstructive sleep apnea syndrome (OSAS) and coronary artery calcification (CAC) are considered to be related with the presence of coronary artery disease (CAD). In this study we evaluate the association between OSAS and presence of subclinical atherosclerosis assessed by tomographic coronary calcium score in patients who had OSAS but no history of known CAD. METHODS: Seventy-three patients who were asymptomatic for CAD and had suspected OSAS were referred to overnight attended polysomnography. Patients were classified into 4 groups according to the Apnea-Hypopnea Index (AHI). All patients underwent computed tomographic examination for tomographic coronary calcification scoring. Physical examination, sleep study recordings, complete blood count and serum biochemistry were obtained from all patients. RESULTS: In the whole group, AHI levels were weakly correlated with coronary calcium score (r = 0.342, p = 0.003) and body mass index (r = 0.337, p = 0.004), moderately correlated with basal oxygen saturation (r = -0.734, p < 0.001), and strongly correlated with oxygen desaturation index (r = 0.844, p < 0.001). In an univariate analysis, age, AHI, basal oxygen saturation, and oxygen desaturation index were associated with CAC in patients with OSAS. In a multiple logistic regression model, age (OR 1.108,%95 CI 1.031-1.191, p = 0.005) and AHI (OR 1.036,% 95 CI 1.003-1.070, p = 0.033) were only independent predictors of CAC in patients with OSAS with a sensitivity of 88.9% and 77.8% and a specificity of 54.3% and 56.5% respectively. CONCLUSIONS: Our findings suggest that in patients with moderate or severe OSAS and advanced age, physicians should be alert for the presence of subclinical atherosclerosis.
RESUMO
BACKGROUND: Some biomarkers can be helpful in the diagnosis of pulmonary embolism (PE) and determining of severity and prognosis of the disease. In this study, we aimed to analyze the elevated cardiac troponin I (cTnI) levels and its association with electrocardiography (ECG) and transthoracic echocardiography (TTE) findings in patients with PE. METHODS: Totally 106 patients with suspected PE were included in the study. PE was confirmed in 63 of them, whereas it was excluded in the remaining 43 patients. Levels of cTnI were measured in all patients before the prescription of the anticoagulation therapy. RESULTS: High cTnI levels were found in 50.8% of patients with PE, and in 11.6% of patients without PE (P<0.001). Sensitivity and specificity of the test for the diagnosis of PE were 50.7%, 88.3% respectively. ECG findings were similar in PE patients having either elevated or normal cTnI levels. Approximately 75% of the PE patients with high cTnI had normal ECG findings; the most common pathological changes seen in ECG were S1Q3T3 pattern (~31%). TTE findings were not found to be distinguishing in the patients with suspected PE and high cTnI levels. Pulmonary hypertension (PHT) was the most common echocardiographic finding (~74%) in patients with PE and elevated cTnI levels. However, there was not a statistically significant difference between TTE findings in PE patients with increased and normal cTnI levels. CONCLUSIONS: In patients presenting with clinical, electrocardiographic and echocardiographic features suggesting pulmonary embolism, increased serum cTnI levels endorse the diagnosis of severe PE.
RESUMO
The aim was to investigate the prevalence of VKORC1 and CYP2C9 genotypes in patients requiring anticoagulant therapy in two different region's populations of Turkey. The recent cohort included 292 patients that needed anticoagulant therapy, and who had a history of deep vein thrombosis and/or pulmonary artery thromboembolism. Genomic DNA was isolated from peripheral blood samples and the StripAssay reverse hybridization or Real Time PCR technique was used for genotype analysis. Genotypes for CYP2C9 were detected as follows: 165 (56.5 %) for CYP2C9*1/*1, 67 (23.0 %) for CYP2C9*1/*2, 25 (8.6 %) for CYP2C9*1/*3, 9 (3.0 %) for CYP2C9*2/*2, 21 (7.2 %) for CYP2C9*2/*3, 5(1.7 %) for CYP2C9*3/*3 for CYP2C9 and the allele frequencies were: 0.723 for allele*1, 0.182 for allele*2 and 0.095 for allele*3 respectively. Genotypes for VKORC1 were detected as follows: 64 (21.9 %) for GG, 220 (75.4 %) for GA and 8 (2.7 %) for AA alleles. The G allele frequency was detected as 0.596, and the A allele frequency was 0.404. The VKORC1 1639 G>A and CYP2C9 mutation prevalence and allele frequency of the current results from two different populations (Sivas and Canakkale) showed similarly very variable profiles when compared to the other results from the Turkish population.

INTRODUCTION: This study, to examine the outcomes of the respiratory disability assessment in our clinic. MATERIALS AND METHODS: The reports of 136 patients who attended the chest diseases clinic between January 2010 and June 2011 for the assessment of the respiratory disability were examined retrospectively. RESULTS: Of 10.457 patients who presented in 18 months, 136 (1.3%) requested the assessment of the respiratory disability. The patients' average age was 51 ± 12 years and 118 (87%) were male. Farmers constituted 19.8% of the patients and mine and foundry workers 10.7% of the patients. The most frequent symptoms were dyspnea (91.2%) and cough (76.5%). The most frequent radiological pattern was reticular and nodular opacities (38.2%). The workup led to a diagnosis of chronic obstructive pulmonary disease in 64 patients (47%) and of interstitial pulmonary disease/pneumoconiosis in 19 (14%) patients. No respiratory disease was found in 19 patients. Among 44 (32.4%) patients for whom disability rate was calculated, 8 (18.2%) had an incapacity rate of 60% or higher and 13 had 0%. The disability rates showed positive correlations with age, the duration of the respiratory symptoms and PaCO2 level (respectively r= 0.395, p= 0.008; r= 0.391, p= 0.009; r= 0.790, p< 0.001), and negative correlations with FVC, FEV1 and PaO2 levels (respectively r= -0.681, p< 0.001; r= -0.766, p< 0.001; r= -0.661, p= 0.003). Linear regression analysis showed that high PaCO2 value is a determinant for a high disability rate (r= 0.902, p= 0.014). Furthermore, smokers had higher disability rates than non-smokers (p< 0.001). CONCLUSION: We believe that new evidence-based guidelines that will resolve the medicolegal and social obscurities are needed.

BACKGROUND: Malignant mesothelioma (MM) is an insidious tumor with poor prognosis, arising from mesothelial surfaces such as pleura, peritoneum and pericardium. We here aimed to evaluate the demographic, clinical, and radiological features of patients with MM followed in our center as well as their survival. METHODS: The study included 228 patients (131 male, 97 female) who were followed up in our institution between 1993 and 2010 with the diagnosis of MM. RESULTS: The mean age was 59.1 years in men and 58.7 years in women and the sex ratio was 1.4:1 in favor of males. Environmental asbestos exposure was present in 86% of the patients for a mean duration of 40±20 years (range: 3-70). Pleural effusion and thoracic/abdominal pain were the most common presenting signs and symptoms (70.2% and 57.8%, respectively). One hundred-thirteen (66%) patients were treated with platinum-based combination chemotherapy (PBCT) plus supportive care (SC) and 67 (34%) patients received SC alone. The median follow-up time was 10.0 months. The median overall survival was significantly improved with PBCT plus SC compared to SC alone (11.4 vs. 5.1 months; p=0.005). The 6, 12, 18, and 24-month survival rates were significantly improved with PBCT plus SC compared to SC alone (72%, 43%, 19%, and 2% vs. 49%, 31%, 11%, and 1%). CONCLUSION: The survival of patients with MM improved in patients treated with PBCT. The survival advantage continued 12- and 24-month after the initial time of combination chemotherapy.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a progressively debilitating disease limiting patients' survival. The prognosis of COPD worsens with the addition of right ventricular (RV) failure. Red cell distribution width (RDW) is a measure of variability in the size of circulating erythrocytes, and is a powerful predictor of outcomes in patients with both chronic and acute left heart failure. Here we attempted to test whether RDW could provide an early marker of RV failure in patients with COPD. METHODS: Thirty-nine consecutive patients with COPD were enrolled in the study. All patients had at least 10 years' history of COPD, and all were treated appropriately. Thirty-nine age-matched and sex-matched individuals were enrolled for comparison. Red cell distribution width was obtained in all patients before transthoracic echocardiography. Right ventricular parameters were evaluated, and RV failure was identified via lateral tricuspid annulus longitudinal motion and systolic-tissue Doppler velocity, using transthoracic echocardiography. RESULTS: Patients with COPD had significantly higher RDW values compared with control subjects (patients with COPD, mean ± SD, 16.1 ± 2.5; range, 12.3 to 23.3; control subjects, mean ± SD, 13.6 ± 1.3; range, 11.7 to 18.3; P < .001). In multivariable logistic regression, the presence of high RDW was the only parameter independently predicting RV failure in patients with COPD (odds ratio, 2.098; P = .017). Levels of RDW, obtained before echocardiography, predicted the presence of RV failure with a sensitivity of 70% and specificity of 93.1%, with a cutoff value of >17.7. CONCLUSION: Red cell distribution width may be used to identify COPD patients with RV failure.

Red cell distribution width (RDW) is strongly associated with prognosis in cardiopulmonary disorders such as coronary artery disease, acute myocardial infarction, acute and chronic heart failure, and pulmonary hypertension. However, its prognostic significance in acute pulmonary embolism (PE) is unknown. The aim of this study was to investigate the relation between admission RDW and early mortality in patients with acute PE. One hundred sixty-five patients with confirmed acute PE were included. Patients with previous treatment for anemia, malignancy, or chronic liver disease, those with dialysis treatment for chronic renal failure, and those who received erythrocyte suspension for any reason were excluded. A total of 136 consecutive patients with acute PE were evaluated prospectively. According to receiver-operating characteristic curve analysis, the optimal cut-off value of RDW to predict early mortality was >14.6%, with 95.2% sensitivity and 53% specificity. Patients were categorized prospectively as having unchanged (group 1) or increased (group 2) RDW on the basis of a cut-off value of 14.6%. The mean age of patients was 63 ± 15 years. The mean follow-up duration was 11 ± 7 days, and 21 patients died. Among these 21 patients, 1 (1.6%) was in group 1 and 20 (27%) were in group 2 (p <0.001). Increased RDW >14.6% on admission, age, presence of shock, heart rate, oxygen saturation, and creatinine level were found to have prognostic significance in univariate Cox proportional-hazards analysis. Only increased RDW >14.6% on admission (hazard ratio 15.465, p = 0.012) and the presence of shock (hazard ratio 9.354, p <0.001) remained associated with increased risk for acute PE-related early mortality in a multivariate Cox proportional-hazards model. In conclusion, high RDW was associated with worse hemodynamic parameters, and RDW seems to aid in the risk stratification of patients with acute PE.

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.
