RESUMEN

AIM: Maximum mid-expiratory flow (MMEF) is one of the pulmonary function tests that report small airway disease. Our study aimed to investigate the role of MMEF values in asthma control, the prevalence of small airway disease, and their effect on asthma control in patients with asthma with normal forced expiratory volume in one second (FEV1) values. MATERIAL AND METHOD: Patients who presented to the Chest Diseases outpatient clinic of our hospital between 2018 and 2019 and were diagnosed as having asthma were included in the study. The characteristics of the patients, pulmonary function tests, their asthma treatment, and asthma control test (ACT) scores were recorded. Patients with FEV1 <80 in the pulmonary function test, those with additional lung disease, those who had an attack in the last 4 weeks, and patients who smoked were excluded from the study. MMEF <65 was defined as small airway disease. RESULTS: The MMEF% and MMEF (L/s) values of the group with uncontrolled asthma were found to be statistically significantly lower than those of the controlled asthma group (p = 0.016 and p = 0.003, respectively). MMEF% and MMEF (L/s) values in those with wheezing were found to be significantly lower compared with those without wheezing (p = 0.025 and p = 0.049, respectively). The MMEF% and MMEF (L/s) values of the patients with nocturnal symptoms were found to be statistically significantly lower than in patients without nocturnal symptoms (p = 0.023 and p = 0.041, respectively). ACT values of patients with MMEF <65 were found to be statistically lower than those of patients with MMEF >65 (0.047). CONCLUSION: Considering small airway disease in patients with asthma may be beneficial in clinical practice.

RESUMEN

OBJECTIVE: This study aimed to compare the success rate of 3 different drug prescription policies: Free drugs with online system prescription, free drugs with doctor's prescription, and drugs paid for by patients with doctor's prescription. MATERIAL AND METHODS: The effect of 2 different Ministry of Health (MoH) projects with free-of-charge and self-payment pharmacotherapies for smoking cessation were compared. Patients who completed 6 months of pharmacotherapy and follow-up were evaluated. The first period was free-of-charge medication, which was determined by an online system, the following period was the self-payment period, and the third period was free medication, which was prescribed by a doctor. In all the groups, smoking habits in pack years and comorbidities of the patients were recorded, and pulmonary function tests (PFTs) and expiratory carbon dioxide (CO2) measurements were performed. Patients who had an expiratory CO2 level >5 ppm at the control visits were accepted as quitters. RESULTS: A total of 829 patients with 438 patients in the first free-of-charge period (group 1), 111 in the self-payment period (group 2), and 280 in the second free-of-charge period (group 3) were enrolled in the study. Smoking cessation rates were significantly higher in the self-payment medication group (25%) according to the MoH's free-of-charge project groups. There was no difference in smoking cessation rates between the 2 free-of-charge medication project groups (15% in group 1 and 11% of group 3). Among all the patients, we compared 124 patients who quit smoking with 705 patients who did not. The quitters were older, mostly male, and heavier smokers. In addition, the number of patients with chronic obstructive pulmonary disease and obstructive PFT rates were higher among the quitters. Their dependency score, PFTs, and the use of free medication was lower, and treatment duration was longer. Independent factors that increased smoking cessation success were longer treatment duration, lower dependency score, and self-payment of medication. CONCLUSION: Free medications provided via 2 different modalities did not increase the smoking cessation success. Paying for the medication, lower dependency score, and longer treatment duration increased smoking cessation success independently.

RESUMEN

PURPOSE: To use ultrasonography (USG) for the evaluation of lung parenchyma in patients with sarcoidosis, andto compare the USG findings with the results of a high-resolution computerized tomography (HRCT) and pulmonary function test-carbon monoxide diffusion test (PFT-DLCO), which are commonly used methods in the evaluation of parenchymal involvement in sarcoidosis. MATERIAL AND METHODS: Patients with sarcoidosis and healthy controls were enrolled in the study between January 2015 and December 2017. The clinical findings, HRCT and PFT-DLCO results of all subjects were recorded, and USG findings and comet tail artifact (CTA) measurements were recorded by another pulmonologist. The USG, HRCT and SFT-DLCO findings were compared between the two groups. Based on the findings of theclinical-radiologic investigations and PFT-DLCO, as the current gold standard in diagnosis, the sensitivity and specificity of USG in demonstrating lung parenchyma involvement in sarcoidosis patients were estimated. FINDINGS: The sarcoidosis group consisted of 79 patients and the control group included 34 subjects. The mean number of CTAs in the sarcoidosis and control groups was 33.4 and 25, respectively (p=0.001). In the sarcoidosis group, the number of CTAs in patients with DLCO% <80 and ≥80% was 37.4 and 29.7, respectively (p=0.011), and a negative correlation was identified between the number of CTAs and DLCO% (p=0.019 r=-0.267). The mean number of CTAs in patients with and without parenchymal involvement in HRCT was 36 and 25.5, respectively (p=0.001). The number of CTAs in the patients with sarcoidosis with a normal DLCO% value (≥80%) was higher than in the control group (p=0.014). The diagnostic sensitivity and specificity of thoracic USG were found to be 76% and 53%, respectively. CONCLUSION: The number of CTAs in patients with sarcoidosis was higher than that of the healthy controls. The number of CTAs in patients with sarcoidosis with parenchymal involvement in HRCT and/or a low DLCO (<80%) was also elevated. Thoracic USG has a high sensitivity (76%) in demonstrating parenchymal involvement in patients with sarcoidosis.

RESUMEN

OBJECTIVE: To evaluate the role of ultrasonography (USG) in the diagnosis of bleomycin-induced pulmonary toxicity (BT). MATERIAL AND METHODS: The study included patients with suspected BT during treatment with bleomycin due to various oncologic diseases between June 2015 and May 2017. The patients initially underwent clinical and high-resolution computed tomography (HRCT) examinations and pulmonary function tests (PFT)-diffusing capacity of the lung for carbon monoxide (DLCO), followed by registration of USG findings-number of comet tail artifact (CTA) images by a different pulmonologist. We compared the findings from USG, HRCT, and PFT-DLCO tests between BT and non-BT groups. With the diagnosis based on clinical-radiologic and PFT-DLCO assessments taken as the gold standard, we determined the sensitivity and specificity of the USG outcomes for diagnosis of BT. RESULTS: The study included a total of 30 patients. Nine patients were diagnosed as having BT according to their clinical and radiologic findings and PFT-DLCO measurements. The mean number of CTA images was 68.7±22 in patients with BT vs 28.2±9.3 in those without BT (P<.001). The difference in CTA images between the patients with and without ground glass density was statistically significant (28.3±9.5 and 64.6±24.5, respectively, P<.001). In patients with BT, there was a negative correlation between the number of CTAs and DLCO% and FVC% values (P=.004; P=.016). USG had a sensitivity of 100%, and a specificity of 95% diagnosing BT in selected patients. CONCLUSION: In bleomycin-induced toxicity, USG findings are correlated with HRCT and PFT-DLCO findings, with a remarkably increased number of CTAs in BT. Thoracic USG examination is a diagnostic tool with a high sensitivity and specificity for diagnosing BT.

RESUMEN

OBJECTIVES: Sepsis is a disease with high mortality that is frequently observed in intensive care units. This study aimed to determine the risk factors affecting mortality of patients with sepsis who were followed up in the intensive care unit (ICU). We aimed to contribute to literature by evaluating the relationship between mortality and pro-brain natriuretic peptide (pro-BNP9), C-reactive protein (CRP), thrombocyte count, Acute Physiology and Chronic Health Evaluation (APACHE) II score, Sequential Organ Failure Assessment (SOFA) score, duration of hospitalization in the intensive care unit, and the presence of multidrug-resistant microorganism. MATERIAL AND METHODS: Patients hospitalized in ICU because of the diagnosis of sepsis and septic shock between December 2010 and June 2012 were included in this retrospective study. RESULTS: A total of 141 patients, including 74 male (52.5%) and 67 female (47.5%) patients, were involved in the study, and the median age was 66.8±17.9 years. Sixty-nine patients (48.9%) were discharged from the ICU; however, 72 patients (51.1%) were exitus. Multidrug-resistant microorganism was detected in 34 patients (24.1%). The patients' median SOFA score was 9.16±3.16, median APACHE-II score was 24.9±7.83, and median duration of hospitalization in the ICU was 8.44±11.61 days. It was found that mortality rate significantly increased in patients with the APACHE-II score of 24.5 and over, SOFA score of 8.5 and over, pro BNP value of 7241 ng/L and over, and CRP value of 96.5 mg/dL and over. Mortality rate was detected to be higher in patients undergoing invasive mechanical ventilation than in patients undergoing non-invasive mechanical ventilation. When thrombocyte count and mortality were associated with each other, it was found that the median value was 86000 mg/dL in exitus patients, whereas it was 185000 mg/dL in patients discharged from the ICU. CONCLUSION: It was revealed that increased APACHE-II score, increased SOFA score, increased pro BNP score, increased CRP, the presence of multidrug-resistant microorganism, and decreased thrombocyte count elevated the rate of mortality. However, no relationship was observed between the duration of hospitalization in the ICU and mortality.
