Öğe Anticoagulant therapy for acute venous thromboembolism(Turkısh soc cardıology, cobancesme sanayı cad no 11, nısh ıstanbul a blok kat 8 no 47-48, yenıbosna, bahcelıevler, ıstanbul 34196, turkey, 2017) Ermis, Hilal; Ermis, NecipDeep vein thrombosis (DVT) and pulmonary embolism (PE) are currently defined as venous thromboembolism (VTE) since they share pathophysiological features and the treatment is similar in many respects. It has been determined that more than 90% of PE cases originate from DVT in the legs. PE, which is difficult to diagnose, has a mortality rate of 12% when untreated. The worldwide increase in obesity, cancer diseases, and average survival time also contribute to the increase in the incidence of VTE. Traditional treatment of VTE includes heparin, low-molecular-weight heparin, and warfarin. Despite availability for oral use, warfarin has a narrow therapeutic range and a wide range of food interactions. After many years of research, new oral anticoagulant agents (NOACs) are expected to overcome these handicaps in treatment. In this review, the use of NOACs in the treatment of VTE is investigated in the light of current guidelines.Öğe Anticoagulant therapy for acute venous thromboembolism(Turkish Soc Cardiology, 2017) Ermis, Hilal; Ermis, NecipDeep vein thrombosis (DVT) and pulmonary embolism (PE) are currently defined as venous thromboembolism (VTE) since they share pathophysiological features and the treatment is similar in many respects.

In this case report, we presented the development of pulmonary arterial hypertension in a 22-year-old woman who underwent BMT due to aplastic anemia. Her symptoms on admission included shortness of breath, palpitations and fatigue. Pulmonary hypertension was classified with right heart catheterization as pul monary arterial hypertension. The patient's laboratory, echocardiographic and hemodynamic findings improved with pulmonary arterial hypertension-specific treatment. Pul monary arterial hypertension should be considered in the differ ential diagnosis of BMT patients with 'unexplained' hypoxemia or respiratory distress.Öğe A Case of Tracheobronchopathia Osteochondroplastica Mimicing Endobronchial Mass(Aves, 2010) Ermis, Hilal; Sen, Nazan; Erbay, Gurcon; Canpolat, Emine TubaTracheobrcmchopathia ostecwhondroplastica (TO) is a rare benign disorder with unknown aetiology. The condition is diaracteri/ed by submuck)sal nodulcs progressing slk)wly. TO usually has been repotted in literature as sporadic CaSCS. Although endobronchial lesikms considered as malignancy especially in the presence of smoking history, rarely it may be a benign condition. In this kind of situations bonchoscopic inspection comes into prominence. Seventy-one year -old man who is asymptomatic and heavy smoker, was admitted to our clinic because of the suspicious endobronchial lesion determined on the thorax computed tomography which was performed incidentally. The diagnosis of TO is confirmed histopathologically accompanied by radiologic and bronchoscopic findings.Öğe Comparison of the Effects of the Somatotype on the Physical Activity, Kinesiophobia, and Fatigue Levels of Obstructive Sleep Apnea Syndrome Patients and Healthy Individuals(Iranian Scientific Society Medical Entomology, 2021) Toy, Seyma; Ciftci, Rukiye; Senol, Deniz; Kizilay, Fatma; Ermis, HilalBackground: We aimed to compare the physical activity, kinesiophobia, and fatigue levels of obstructive sleep apnea syndrome (OSAS) patients and healthy individuals in terms their somatotypes. Methods: A total of 165 individuals were enrolled referred to the Department of Chest Diseases Sleep Disorders Center Outpatient Clinic of Inonu University, Malatya, Turkey in 2018. The somatotype analysis was conducted using the Heath- Carter method, the fatigue level was assessed using the Functional Assessment of Chronic Illness Therapy (FACIT) fatigue scale, the kinesiophobia level was assessed using the Tampa Scale for Kinesiophobia (TSK), and the physical activity level was assessed using the International Physical Activity Questionnaire (IPAQ). Results: The results of the somatotype analysis revealed 3 different somatotypes in the healthy individuals and the OSAS patients' mesomorph endomorph, endomorphic mesomorph, and mesomorphic endomorph. When comparing the somatotypes of the healthy individuals and the OSAS patients, statistically significant differences were found in the FACIT scores of the mesomorph endomorphs, the IPAQ and FACIT scores of the endomorphic mesomorphs, and the TSK and FACIT scores of the mesomorphic endomorphs (P<0.05). Conclusion: In all three somatotypes of the OSAS patients, the fatigue index scores were higher when compared to those of the healthy individuals. Moreover, when compared with the healthy individuals, the physical activity levels of the endomorphic mesomorphs with OSAS were low, while the kinesiophobia scores of the mesomorphic endomorphs with OSAS were high. Based on the results of this study, in OSAS patients, the endomorphic mesomorph somatotype could be a risk factor for reduced physical activity, while the mesomorphic endomorph somatotype could be a risk factor for increased kinesiophobia.Öğe Delays in Diagnosis and Treatment in Patients Underwent Endobronchial Ultrasound-Transbronchial Needle Aspiration (EBUS-TBNA)(Wiley-Hindawi, 2022) Gulcek, Emine; Yalcinsoy, Murat; Gulcek, Ilham; Guven, Arzu Nakis; Ermis, Hilal; Aytemur, Zeynep AyferObjectives. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has been recognized as the first method of choice in the diagnosis of mediastinal and hilar lesions. Although the procedure is commonly used, there is no study assessing its contribution to the duration required for diagnosis and treatment. In this study, we aimed to determine the extent of diagnosis and treatment delays when using the EBUS-TBNA procedure and to address the possible factors contributing to these delays. Materials and Methods. The demographic data, pathological diagnosis, need for additional procedures, symptoms, presenting complaints, and the time until the beginning of treatment were recorded retrospectively in all patients who had undergone EBUS-TBNA. Results. A total of 134 patients (mean age 60.7 & PLUSMN; 12 years, M/F: 78/56) were included. Delay of the patients was found in 60.4% (n = 81), delayed referral in 35.8% (n = 48), diagnosis delays in 84.3% (n = 113), treatment delays in 38.8% (n = 52), and total delay in 73.1% (n = 98) of the patients. A statistically significant association was found between referral delay and total delay with age groups (p=0.006) and between patient delay and the presence of symptoms (p=0.027). EBUS-TBNA was found to have the lowest effect among all delay parameters (beta: 0.104, p < 0.001) in the regression analysis. When diagnosis times' subgroups were compared, EBUS-TBNA was found to have the least effect (correlation coefficient: 0.134, p=0.004). Conclusion. We found that approximately 3/4 of the patients had a delay and this is not acceptable in real terms. Considering that the patient burden is increasing day by day, it is necessary to make a radical change in health care or a change in strategy in order to prevent delays. EBUS-TBNA, which is in the diagnosis delay subgroup, is less invasive and accelerates the process.Öğe Diagnostic and treatment outcomes of patients with pulmonary tuberculosis in the first year of COVID-19 pandemic(Who Eastern Mediterranean Regional Office, 2022) Yakupogullari, Yusuf; Ermis, Hilal; Kazgan, Zeynep; Otlu, Baris; Bayindir, Yasar; Gulbas, Gazi; Tanriverdi, ElifBackground: The COVID-19 pandemic has put a significant strain on human life and health care systems, however, little is known about its impact on tuberculosis (TB) patients. Aims: To assess the impact of COVID-19 pandemic on pulmonary tuberculosis (PTB) diagnosis, treatment and patient outcomes, using the WHO definitions. Methods: A cross-sectional study was conducted in Malatya region, Turkey (population 800 000). Data on regional PTB test numbers, case notification rates and PTB patients' clinical characteristics and treatment outcomes were collected. Data from the first pandemic year (2020) were compared to data from the previous 3 years (2017-2019). The attitudes and experiences of patients were analysed. Results: Despite a non-significant 22% decrease in annual PTB case notifications (P = 0.317), the number of TB tests performed (P = 0.001) and PTB patients evaluated (P = 0.001) decreased significantly during the pandemic year compared with the previous 3 years. The proportion of patients with high (3/4+) sputum acid-fast bacilli grades (P = 0.001), TB relapse (P = 0.022) and treatment failure (P = 0.018) increased significantly. The median 64.5-day treatment delay detected in 2017-2019 increased significantly to 113.5 days in 2020 (P = 0.001), due primarily to patients' reluctance to visit a health care facility. Conclusion: In addition to the problems with case detection, this study shows notable deterioration in several indicators related to the severity, contagiousness and poor outcomes of TB, which had already been suppressed for decades.Öğe Effects of varenicline on lung tissue in the animal model(Soc Brasileira Pneumologia Tisiologia, 2020) Ermis, Hilal; Parlakpinar, Hakan; Elbe, Hulya; Vardi, Nigar; Polat, Alaaddin; Gulbas, Gazi[Abstract Not Available]Öğe Emerging Tuberculosis Among Patients with Previous COVID-19(Bilimsel Tip Yayinevi, 2022) Yakupogullari, Yusuf; Tanriverdi, Elif Seren; Ermis, Hilal; Otlu, BarisCOVID-19 patients have a higher incidence of opportunistic infections, but there is little information on tuberculosis (TB). In this study, it was aimed to determine any possible contribution of COVID-19 in TB emergence among patients diagnosed with TB during the pandemic. A retrospective screening of the regional TB laboratory's records identified TB patients diagnosed in the Malatya region between April 1, 2020, and December 31, 2021. Medical data of TB patients with a prior COVID-19 were evaluated. During the study period, 171 TB patients were diagnosed in the region, with 26 also infected with SARS-CoV-2. Patients' histories revealed that 10 (38.5%) of these 26 patients developed TB symptoms in a median 68.5 days after COVID-19. Four patients had one-week to two-month corticosteroid treatment due to severe COVID-19, and one had a hematological malignancy history. However, the remaining five patients had no significant predisposing factor for TB relapse. Four out of 10 patients were free of any finding for active TB before COVID-19. Severe COVID-19 may have some obvious implications for TB reactivation, but there was no conclusive evidence of such an effect in mild to moderate COVID-19. Nonetheless, inquiring about COVID-19 histories from TB patients in large-scale studies may provide high-quality evidence about the interactions between the two pathogens.Öğe The evaluation of sensory gating with P50 paradigm in chronic obstructive pulmonary disease(European Respiratory Soc Journals Ltd, 2012) Kamisli, Ozden; Ermis, Hilal; Kamisli, Suat; Gulbas, Gazi; Ozcan, Cemal[Abstract Not Available]Öğe Exposure to SO2 does not have a chronic effect on pulmonary functions of apricot workers(Taylor & Francis Ltd, 2010) Ermis, Hilal; Gokirmak, Munire; Yildirim, Zeki; Yologlu, Saim; Ankarali, HandanThe authors have previously demonstrated that apricot sulfurization workers develop asthma-like syndrome during apricot sulfurization due to exposure to sulfur dioxide (SO2) gas. The aim of the current study was to demonstrate if exposure to SO2 gas had any chronic effects on pulmonary functions and bronchial reactivity of the workers. Twenty-five apricot sulfurization workers and a control group were included in the study. Physical examination, skin prick tests, pulmonary function tests (PFTs), and bronchoprovocation tests (BPTs) were performed before and after the season of sulfurization in the worker group. Skin prick tests, PFTs, and BPTs were performed also in the control group without a history of exposure to SO2 gas. There was no statistically significant difference between PFT and BPT results of the workers and the control group. Comparison of the PFT results of the workers before and after the season of apricot sulfurization neither reveal a significant difference. Four (16%) out of 25 workers were positive for BPTs before the period. Only one worker who had a negative BPT result before the sulfurization season was positive afterwards. The lack of a chronic effect on pulmonary functions is consistent with the diagnosis of asthma-like syndrome in apricot sulfurization workers.Öğe Impact of rem-related obstructive sleep apnea therapy on anxiety, depression and daytime sleepiness(Bayrakol Medical Publisher, 2022) Geckil, Aysegul Altintop; Ermis, HilalAim: Obstructive Sleep Apnea (OSA) is characterized by repetitive episodes of complete or partial upper airway obstruction during sleep. Patients who slept at least 30 minutes in REM sleep, total apnea-hypopnea index (AHI)>5 and REM AHI/NREM AHI>2 are defined as REM-related OSA. We investigated the efficacy of treatment on anxiety, depression and daytime sleepiness in REM-related OSA. Material and Methods: A total of 110 patients with REM-related OSA participated in the study. Patients were divided into two groups; the treatment group consisted of patients who received treatment (n:38) and the non-treatment group who refused to receive treatments (n:72). Of the 38 patients treated, 33 had mild disease and 5 had moderate disease. Sixty-seven of the 72 patients who did not receive treatment had mild disease and 5 had moderate disease. Both groups completed the HADS (Hospital Anxiety-Depression Scale), ESS (Epworth Sleepiness Scale) questionnaires. SPSS was used for data analysis. Results were expressed as mean and standard deviation. T-test and chi-square tests were performed to compare cases. A p-value <0.05 was considered statistically significant. Results: There was no statistically significant difference between the groups, in terms of age, gender, height, weight, and body mass index (BMI). No statistically significant difference was found between the two groups in terms of polysomnography parameters AHI, REM AHI, arousal index, periodic leg movement (PLM) index, sleep latency, REM latency, minimum oxygen saturation (SPO2), and cumulative percentage of time spent at saturation below 90%. HADS- Anxiety, HADS- Depression and ESS scores were significantly higher in the non-treatment group in comparison to the treatment group (p=0.011, p=0.016, p=0.005, respectively). Discussion: The results of our study showed that treatment has positive effects on anxiety, depression and daytime sleepiness, which are indicative of the quality of life in patients with REM-related OSA.Öğe Investigation of neuromuscular transmission in patients with chronic obstructive pulmonary disease: A preliminary report(European Respiratory Soc Journals Ltd, 2012) Kaplan, Yuksel; Gulbas, Gazi; Ermis, Hilal; Kamisli, Ozden; Kamisli, Suat; Ozcan, Cemal[Abstract Not Available]Öğe A Life-threatening Complication of Deep Venous Thrombosis; Phlegmesia Cerulea Dolens(Emergency Medicine Physicians Assoc Turkey, 2013) Kaya, Mer; Yucel, Neslihan; Gulbas, Gazi; Ermis, Hilal; Kutlu, RamazanPhlegmasia cerulea dolens is a rare condition caused by complete venous occlusion and often results in tissue necrosis, limb amputation, or death. In this study, a 51 year old female presenting at our emergency department with leg edema, leg pain and cyanosis and was diagnosed with phlegmesia cerulea dolens, which is a life-threatening complication of deep venous thrombosis. Prompt diagnosis and treatment initiation are important to prevent pulmonary emboli, gangrene, amputation, and, ultimately, death.Öğe Neuromuscular transmission in hypoxemic patients with chronic obstructive pulmonary disease(Elsevier, 2013) Gulbas, Gazi; Kaplan, Yuksel; Kamisli, Ozden; Ermis, Hilal; Kamisli, Suat; Ozcan, CemalMany studies have focused on the systemic effects of chronic obstructive pulmonary disease (COPD), but none has examined neuromuscular junction transmission (NMT). We evaluated NMT dysfunction using single-fiber electromyography (SFEMG) in patients with COPD. Twenty patients with COPD and 20 age-matched healthy controls were included in the study. All patients and controls underwent SFEMG. Abnormal NMT was found in seven of 20 patients (35%), but in none of the control subjects. The COPD patients were subgrouped according to the presence of hypoxemia. The patients with normoxemia were classified as Group 1, and the patients with hypoxemia were classified as Group 2. Abnormal NMT was found in six patients in Group 2 and in one in Group 1. While there was significant difference in terms of abnormal NMT between Group 2 and the controls, there was none between Group 1 and the controls. Our results show that NMT abnormalities can be present in hypoxemic patients with COPD. (C) 2013 Elsevier B.V.

OBJECTIVES We compared the ability of the sPESI and SI to predict 30-day and 3-year mortality following PE. PATIENTS AND METHODS Prognostic models based on the sPESI and SI were used to predict the overall 30-day (short-term) and 3-year (long-term) mortality in a cohort of 194 patients with confirmed PE. RESULTS Overall, the mortality rate in this cohort was 9.2% in the first month and 29.9% at 3 years. The sPESI categorized fewer patients as low risk (41.7%; 81 of 194 patients) when compared with the SI lower than 1 (74.7%; 145 of 194 patients). Importantly, patients classified as low risk in the sPESI had no 30-day mortality compared with 2.1% of patients (3 of 145) classified as low-risk based on the SI. The 3-year mortality rate in low-risk patients according to the sPESI was lower than that in low-risk patients identified based on the SI (4.9% vs. 20.7%; P < 0.0001). While a multivariate Cox analysis showed that both the SI and sPESI were independent prognostic variables for 3-year mortality, it showed that only the SI was an independent prognostic variable for 30-day mortality. CONCLUSIONS Both prognostic models allow to stratify the risk of short-and long-term mortality in patients with PE, but the sPESI was better than SI at classifying low-risk patients.Öğe Protective and Therapeutic Effect of Molsidomine on Bleomycin-Induced Lung Fibrosis in Rats(Springer/Plenum Publishers, 2014) Kilic, Talat; Parlakpinar, Hakan; Polat, Alaadin; Taslidere, Elif; Vardi, Nigar; Sarihan, Ediz; Ermis, HilalWe aimed to investigate the preventive and treatment effect of molsidomine (MOL) on bleomycin (BLC)-induced lung injury in rats. Rats were assigned into groups as follows: control group; MOL group, 10 mg/kg MOL was continued orally for 29 day; BLC group, a single intratracheal injection of BLC (2.5 mg/kg), MOL+BLC-preventive group, 10 mg/kg MOL was administered 1 day before the intratracheal BLC injection and continued for 14 days; BLC+MOL-treatment group 10 mg/kg MOL was given on 14th day after the intratracheal BLC injection and continued until sacrifice. All animals were sacrificed on 29th day after BLC administration. The semiquantitative histopathological assessment, tissue levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), reduced glutathione (GSH), total antioxidant status (TAS), total oxidant status (TOS), myeloperoxidase (MPO), and oxidative stress index (OSI) were measured. BLC-provoked histological changes were significantly detected compared to the control group. MOL restored these histological damages in different quantity in the treatment and preventive groups. BLC administration significantly decreased levels of GSH and TAS when compared to controls and these reductions was significantly ameliorated by MOL given prophylactic setting. However, therapeutic MOL administration significantly increased the TAS level decreased by BLC. The levels of MDA, MPO, and TOS were significantly increased with BLM, and these augmentations of MDA and TOS were significantly reduced by MOL given prophylactic setting. Furthermore, the OSI was higher in the BLC group, and this increase was reversed by the MOL administration before and after BLC treatment. In this study, both protective and therapeutic effects of MOL against BLC-induced lung fibrosis were demonstrated for the first time.Öğe Protective effect of dexpanthenol on bleomycin-induced pulmonary fibrosis in rats(Springer, 2013) Ermis, Hilal; Parlakpinar, Hakan; Gulbas, Gazi; Vardi, Nigar; Polat, Alaadin; Cetin, Asli; Kilic, TalatDespite extensive studies, there is no effective treatment currently available other than pirfenidone for idiopathic pulmonary fibrosis. A protective effect of pantothenic acid and its derivatives on cell damage produced by oxygen radicals has been reported, but it has not been tested in bleomycin (BLM)--induced pulmonary fibrosis in rats. Therefore, we aimed to investigate the preventive effect of dexpanthenol (Dxp) on pulmonary fibrosis. Thirty-two rats were assigned to four groups as follows: (1) control group, (2) dexpanthenol (Dxp) group; 500 mg/kg Dxp continued intraperitoneally for 14 days, (3) bleomycin (BLM) group; a single intratracheal injection of BLM (2.5 mg/kg body weight in 0.25-ml phosphate buffered saline), and (4) BLM + Dxp-treated group; 500 mg/kg Dxp was administered 1 h before the intratracheal BLM injection and continued for 14 days i.p. The histopathological grades of lung inflammation and collagen deposition, tissue levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and myeloperoxidase (MPO) were measured. BLM provoked inflammation and collagen deposition (p < 0.0001), with a marked increase in myeloperoxidase (MPO) activity resembling increased inflammatory activity (p < 0.0001), which was prevented by Dxp (p < 0.0001, p = 0.02). BLM reduced tissue activities of SOD, GPx, and CAT compared to controls (p = 0.01, 0.03, 0.009). MDA was increased with BLM (p = 0.003). SOD (p = 0.001) and MDA (p = 0.016) levels were improved in group 4. The CAT levels in the BLM + Dxp group were close to those in the control group (p > 0.05). We showed that Dxp significantly prevents BLM-induced lung fibrosis in rats. Further studies are required to evaluate the role of Dxp in the treatment of lung fibrosis.Öğe Pulmonary Embolism in Young and Elderly Patients: Clinical Characteristics, Laboratory and Instrumental Findings and Differences Between Age Groups(Bilimsel Tip Publishing House, 2010) Sen, Nazan; Ermis, Hilal; Altinkaya, Naime; Ermis, Necip; Karatasli, Meltem; Ulubay, GayeObjective: The mortality and incidence of pulmonary thromboembolism (PE) increases with advancing age. Despite the diagnostic developments in recent years, the disease is still difficult to diagnose especially in elderly people. The aim of this study was to compare the clinical presentation of PE in young and elderly patients, examine the parameters determining the risk and prognosis and finally contribute to a decrease in mortality. Material and Method: This study comprised 141 patients diagnosed as PE. The patients were divided into two groups, < 65 years (young group) and 65 years (elderly group). The clinical, laboratory and instrumental findings of the patients were evaluated retrospectively. Results: The most common risk factors in both groups were immobility and recent surgery. Chest pain and hemoptysis were less frequent in the elderly group, while tachycardia was more common in this group of patients (p<0.001, p=0.013 and p=0.047, respectively). Patients with massive PE had a higher value of D-Dimer and electrocardiography (ECG) score compared to patients with non-massive PE (p=0.01, p<0.001, respectively). D-Dimer and cardiac troponin levels and ECG score were higher in patients who died in the hospital when compared to the individuals who survived (p=0.02, p=0.018, p=0.008, respectively). Conclusion: Since PE may present with atypical clinical findings in the elderly, a high level of clinical suspicion is required for the diagnosis. Use of the parameters which can determine the severity, risk and prognosis of the disease at an early stage may enable the initiation of appropriate treatment in the early phases of the disease, thereby decreasing the mortality.Öğe QT dispersion in patients with pulmonary embolism(Springer Wien, 2010) Ermis, Necip; Ermis, Hilal; Sen, Nazan; Kepez, Alper; Cuglan, BilalBackground: Various ECG patterns have been associated with acute pulmonary embolism. However, there is no data regarding the association between QT interval measurements and pulmonary embolism. We aimed to investigate the association between QT dispersion and the severity of pulmonary embolism (PE). Methods: One hundred twenty-nine pulmonary embolism patients (mean age 58 +/- 16.5 years) with ECGs obtained within the first 24 hours of hospital admission were included in the study. Patients were classified into low, intermediate and high-risk groups. We retrospectively measured ECG scores; maximum and minimum corrected QT intervals (QTc(max) and QTc(min)) and corrected QT interval dispersion (QTcd) in each risk group of patients. Results: There was an increasing ECG score through from low to high-risk PE [3 (Interquartile Range, IQR: 2), 5 (IQR: 6) and 10 (IQR: 7) p < 0.0001]. QT interval analysis showed that QTcd was higher in high-risk group than in low and intermediate-risk groups (59.5 +/- 23.4, 69.2 +/- 21, 95.9 +/- 33.2, p < 0.001 and p = 0.01, respectively). Patients who died after diagnosis had significantly higher QTcd values at baseline compared with the QTcd values of surviving patients (89.1 +/- 45.5 to 65 +/- 22.9, p = 0.001). The sensitivity of QTcd > 71.5 ms for prediction of mortality was 71% with a specificity of 73% (p = 0.001). We observed a strong correlation between QTcd and ECG score values (r = 0.69, p< 0.001). There was also a correlation between QTcd values and pulmonary artery pressure (PAP) (r = 0.027, p = 0.001) Conclusion: QTcd is significantly increased in high-risk PE patients compared to intermediate and low-risk patients. In addition, QTcd is significantly correlated with ECG score and PAP.r = 0.27, p = 0.05).
