(Elsevier France-editions Scientifiques Medicales Elsevier, 2021) Yildiz, Hanifi; Alp, Hamit Hakan; Ekin, Selami; Arisoy, Ahmet; Gunbatar, Hulya; Asker, Selvi; Haylu, Mine
Introduction: The SARS-CoV-2 virus affects many organs, especially the lungs, with widespread inflammation. We aimed to compare the endogenous oxidative damage markers of coenzyme Q10, nicotinamide dinucleotide oxidase 4, malondialdehyde, and ischemia-modified albumin levels in patients with pneumonia caused by SARS-CoV-2 and in an healthy control group. We also aimed to compare these parameters between patients with severe and non-severe pulmonary involvement. Methods: The study included 58 adult patients with SARS-CoV-2 pneumonia and 30 healthy volunteers. CoQ10 and MDA levels were determined by high-pressure liquid chromatography. NOX4 and IMA levels were determined by ELISA assay and colorimetric method. Results: Higher levels of CoQ10, MDA, NOX4, and IMA and lower levels of COQ10H were observed inpatients with SARS-CoV-2 pneumonia than in the control group. MDA, IMA, NOX4, and CoQ10 levels were significantly higher in patients with severe pulmonary involvement than in patients with non-severe pulmonary involvement, but no significant difference was observed in CoQ10H levels. CoQ10 levels were significantly and positively correlated with both ferritin and CRP levels. Conclusion: SARS-CoV-2 pneumonia is significantly associated with increased endogenous oxidative damage. Oxidative damage seems to be associated with pulmonary involvement severity.
Association Between Severe Chronic Obstructive Pulmonary Disease and Polyneuropathy
(int Scientific information, inc, 2021) Arisoy, Ahmet; Yilgor, Abdullah; Uney, Ibrahim H.
Background: Chronic obstructive pulmonary disease (COPD) is a life-threatening and devastating disease associated with low-grade systemic inflammation. In adults, the most common disease of the peripheral nervous system is peripheral neuropathy. While most polyneuropathy has a mixed presentation, some cases are motor dominant and others are sensory dominant. We investigated polyneuropathy in patients with COPD and hypothesized that low-grade systemic inflammation and other pathologies in patients with COPD cause peripheral axonal polyneuropathy. Material/Methods: We included 62 patients with COPD without any neurological signs or symptoms, and 30 healthy volunteers with no known neurological or pulmonary diseases as controls. There were 38 men in the COPD group and 17 men in the control group; the mean ages of the 2 groups were 64.88 and 62.7 years, respectively. According to the Global Initiative for Chronic Obstructive Lung Disease COPD report, all COPD patients were group D. After collecting demographic and clinical characteristics of the participants, we performed an electrophysiological examination to investigate polyneuropathy and pulmonary function test results. C-reactive protein, hemoglobin, creatinine, partial carbon dioxide pressure (pCO2) levels were recorded. Electrophysiological examination was performed with a Medelec Synergy device using standard neurographic procedures, and the results were assessed. Results: Significant differences were found for forced expiratory volume in 1 sec (FEV1), %FEV1, forced vital capacity (FVC), %FVC, pCO2, and hemoglobin and creatinine levels, but all participants had a creatinine level within the normal range. There was no difference in sensory neuropathy between the groups, but a significant difference was found in terms of motor neuropathy. Conclusions: As noted in previous studies, systemic inflammation, increased oxidative stress, decreased oxygen pressure, and multiple comorbidities in patients with COPD may all contribute to the development of neuropathy.

(E-century Publishing Corp, 2015) Sunnetcioglu, Aysel; Arisoy, Ahmet; Demir, Yusuf; Ekin, Selami; Dogan, Erkan
Objectives: F-18-fluoro-2-deoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) is extensively used to diagnose and stage of lung cancer. The aim of the current study was to investigate the correlation of demographic, clinical, pathological and radiological factors with primer tumor FDG Uptake in patients with lung cancer. Materials and methods: This cross-sectional, clinical study was performed on a total of 57 lung cancer patients newly diagnosed that underwent FDG PET/CT. In addition to descriptive variables, histopathological diagnosis, tumor site and size, hemoglobin level, red cell distribution width, neutrophil to lymphocyte ratio were noted for each patient. The correlation of these variables to SUVmax values in FDG PET/CT was investigated. Results: A total of 57 patients (4 women, 53 men) with an average age of 60.8 +/- 9.4 (range: 33-89) participated in the study. Histopathological diagnoses were consistent with squamous cell carcinoma (28, 49.1%), adenocarcinoma (15, 26.3%) and small cell cancer (14, 24.6%). The SUVmax of primary tumor was positively correlated with tumor size (P<0.001). The tumor SUVmax of squamous cell carcinoma (SqCC) (17.49 +/- 8.37) was higher than that of adenocarcinoma (AC) (12.80 +/- 4.77) and small cell carcinoma (SCC) (12.40 +/- 5.80) (P=0.038). Conclusion: SUVmax value was significantly higher for squamous cell carcinoma and it SUVmax values in PET scans was found to be positively correlated with tumor size. This study suggests that, tumor size and histologic subtype had influences upon FDG uptake in lung cancer.

(Taylor & Francis Ltd, 2017) Asker, Selvi; Taspinar, Mehmet; Koyun, Hasan; Ozbay, Bulent; Arisoy, Ahmet
Objective: To investigate the associations of G14713A and T29107A polymorphic variants of Caveolin-1 with severe obstructive sleep apnea (OSA). Materials and methods: This study was performed on 86 severe OSA patients and 86 controls. Genotyping was performed to investigate the association of G14713A and T29107A polymorphisms of Caveolin-1 with severe OSA. Results: The distribution of genotypes of T29107A was significantly different between controls and OSA patients with a higher proportion of TT carriers in the OSA group. Conclusion: T29107A-specific genotype of Caveolin-1 may be linked with severe OSA pathogenesis.

(Taylor & Francis Ltd, 2016) Turan, Mahfuz; Ekin, Selami; Ucler, Rifki; Arisoy, Ahmet; Bayram, Yasemin; Yalinkilic, Abdulaziz; Cankaya, Hakan
Conclusions As is known, this study is the first study to evaluate the effect of inhaled steroids on laryngeal microflora. The data support that ICS usage causes changes in the larynx microflora. Purpose The aim of this study was to determine the alteration in larynx microbial flora of the patients treated with ICS comparing the culture results of a control group. In addition, laryngeal microflora was compared to the smears obtained from the vallecula and pharynx. Materials and methods The study included 39 patients (mean age = 45.5 +/- 12.76 years) who had been using a corticosteroid inhaler and control group consisting of 27 persons (mean age = 43.07 +/- 13.23 years). Culture samples were obtained from the pharynx, larynx, and vallecula in the patient and control groups, and they were evaluated in the microbiology laboratory. Obtained culture results were named by the same microbiologist according to the basic microorganism classification method. ResultsCoagulase-negative staphylococci (CNS), Streptococcus viridians (VGS) and candida albicans were detected to grow significantly more in the patient group in all three anatomic localizations compared to the control group. Neisseria spp, basillus spp, and Non-viridans alpha-hemolytic streptococcus were detected to grow significantly more in the control group in all three anatomic localizations compared to the patient group.
Effects of Soft Cervical Collar on Apnea-Hypopnea Index in Patients With Obstructive Sleep Apnea
(int Scientific information, inc, 2025) Bilgin, Mehmet Hakan; Arisoy, Ahmet; Calis, Merve
Background: Obstructive sleep apnea (OSA) is a sleep disorder characterized by recurrent upper airway obstruction, leading to intermittent hypoxia and sleep fragmentation. Continuous positive airway pressure (CPAP) is the criterion standard treatment, but adherence remains a significant challenge. This study aimed to evaluate whether a soft cervical collar could reduce the apnea-hypopnea index (AHI) and improve oxygen saturation by preventing excessive neck flexion and airway collapse, potentially serving as an alternative or adjunctive therapy for OSA. Material/Methods: Ethical approval was obtained, and 34 OSA-diagnosed participants underwent polysomnography (PSG) and CPAP titration. Exclusion criteria ensured a focused cohort. Demographic data, including age, sex, and BMI, were collected. The first night, a 16-channel Embla device was used for PSG, and the apnea-hypopnea index (AHI) was calculated. The second night, patients were monitored with a neck brace for 2 hours, followed by standard PAP titration for the rest of the night during the PSG recording. Results: The mean AHI decreased from 44.44 +/- 26.3 to 36.69 +/- 37.48 with the cervical collar, although this difference was not statistically significant (p=0.08). However, in patients with BMI <30 kg/m2, AHI significantly decreased (p=0.02). The lowest oxygen saturation improved from 76.35 +/- 10.26 to 83.74 +/- 5.02 (p=0.01), indicating better oxygenation with the cervical collar. Conclusions: Although CPAP is the criterion standard for OSA treatment, this study suggests that a neck collar could be an alternative treatment, especially for patients with a BMI below 30. The findings support further exploration of neck collars as a potential intervention in cases where CPAP accessibility or adherence is challenging.

(Taylor & Francis Ltd, 2016) Taken, Kerem; Ekin, Selami; Arisoy, Ahmet; Gunes, Mustafa; Donmez, Muhammet Irfan
Purpose: To investigate the prevalence of erectile dysfunction (ED) in patients with obstructive sleep apnea (OSA) with and without any other comorbidities. Methods: The patient group was newly diagnosed as having OSA (apnea-hypopnea index [AHI]>5/h) using a polysomnographic examination. A group of subjects with simple snoring were included into the control group. Clinically relevant comorbidities were systematically assessed in face-to-face interviews. All patients were asked to complete the 15-item International Index of Erectile Function (IIEF-15) questionnaire for the evaluation of ED. The patients with OSA and ED were evaluated according to these comorbidities. Results: Of the 94 patients, 39 patients were excluded because of severe diseases. OSA was observed in 38 (69.1%) of the 55 patients. ED was seen in 24 (63.2%) patients with OSA, and in 8 (47.1%) patients without OSA (p>0.05). There were no statistical differences between the groups' ages, IIEF scores, and body mass index (BMI) scores. There were statistically significant differences between the groups' AHI scores (p<0.05). There was a significant correlation between the groups' AHI scores, BMI, and age (p<0.05). There was no statistically significant difference in patients with OSA, with and without comorbidity in terms of ED. Conclusion: The rate of ED was higher in patients with OSA who had no other comorbidities. Therefore, ED can be a sensitive marker of OSA.

Is It in Our Genes That We're Going to Have Pulmonary Embolism
(Yuzuncu Yil Universitesi Tip Fakultesi, 2024) Mermi̇t, Buket; Üney, İbrahim Halil; Gunbatar, Hulya; Yıldız, Hanifi; Ekin, Selami; Sunnetcioglu, Aysel; Arisoy, Ahmet
Pulmonary thromboembolism is a disease with high mortality and morbidity, which can be recurrent, difficult to diagnose, yet preventable and treatable. In this study, our aim was to evaluate comorbidities, risk factors, laboratory results, and clinical scoring in patients diagnosed with pulmonary embolism. Our primary goal was to detect genetic mutations in cases of pulmonary embolism with acquired risk factors. Our study is a prospective study that includes clinical information, laboratory tests, Wells scoring, admission, and the prospective history of 60 patients with no previous history of venous thromboembolism (VTE) and no history of anticoagulation use. These patients were admitted to the chest diseases outpatient clinic, emergency department, or hospitalized for another reason and diagnosed with pulmonary thromboembolism. The mean age of the patients was 59.9 ± 18.7 years. The most common presenting complaints were shortness of b reath and sharp chest pain. Nearly half of the patients had at least one comorbid disease. There was at least one genetic/congenital risk factor in all cases, and at least two risk factors were present in more than half of the cases. The most common mutations were plasminogen activator inhibitor type 1 (PAI -1) and Methylenetetrahydrofolate Reductase (MTHFR) heterozygote mutations. Pulmonary embolism continues to be a more prevalent disease with increasing age and associated risk factors. Since there is at least one acquired risk factor in all of our cases, we believe that almost every patient may have an acquired risk factor if the history is thoroughly investigated. We also believe that genetic or thrombophilic conditions may be detected in almost all cases diagnosed with pulmonary embolism. It has been concluded that immobilization and obesity are the most common preventable risk factors associated with VTE.
Is There a Relationship Between Obstructive Sleep Apnea (Osa) and Hearing Loss
(int Scientific Literature, inc, 2016) Ekin, Selami; Turan, Mahfuz; Arisoy, Ahmet; Gunbatar, Hulya; Sunnetcioglu, Aysel; Asker, Selvi; Yildiz, Hanifi
Background: Obstructive sleep apnea (OSA) is a common disorder with an estimated prevalence in the general population of 2-5%. Its main clinical features are loud snoring and breathing stoppage during sleep. Ischemia could be a consequence of noise-induced hearing loss because cochlear oxygen tension is reduced during and after noise exposure. In this study, we evaluated auditory function in patients affected by OSA and simple snoring. Material/Methods: A total of 66 participants (male to female ratio: 40: 26) were included in the study, of which 21 were in the control group, 18 were in the simple snoring group, and 27 were in the OSA patient group. Polysomnography and audiometric examination were performed in all participants. Results: The mean ages of the participants in the control, simple snoring, and OSA groups were 39.14 +/- 9.9, 37.28 +/- 8.2, and 41.56 +/- 8.99 years, respectively. There were no statistically significant differences among groups regarding age or sex; however, there were statistically significant differences among groups in body mass index, apnea-hypopnea index scores, mean saturation, and duration under 90% saturation. In addition, statistically significant differences were found between the patient group and the control and simple snoring groups concerning the mean saturation, duration under 90% saturation, and the extended high frequency of hearing. Conclusions: These data show that snoring may cause hearing loss at extended high frequencies.
Loeffler's Syndrome: an Interesting Case Report
(Wiley, 2016) Ekin, Selami; Sertogullarindan, Bunyamin; Gunbatar, Hulya; Arisoy, Ahmet; Yildiz, Hanifi
Loeffler's syndrome is an acute pneumonia with an unclear cause. One fourth of Loeffler's syndrome patients are idiopathic, although the most common etiologic causes include parasites. Asymptomatic form is usually a reversible, self-limited disease, which does not require a specific treatment regimen. We presented a 17-year-old young man with diagnosis of Loeffler syndrome.

(Daedalus Enterprises inc, 2016) Arisoy, Ahmet; Ekin, Selami; Sertogullarindan, Bunyamin; Gunbatar, Hulya; Sunnetcioglu, Aysel; Aksoy, Nurten; Yildiz, Hanifi
Obstructive sleep apnea (OSA) is a highly prevalent breathing disorder in sleep. It is characterized by intermittent hypoxia leading to hypoxemia, hypercapnia, sleep fragmentation, and increased respiratory efforts. We evaluated the relationship between OSA and myeloperoxidase activity, the oxidative stress index (OSI), total anti-oxidative capacity (TAC), and total oxidative capacity (TOC). METHODS: A total of 70 consecutive subjects (mean age +/- SD: 51.7 +/- 11.7 y) were diagnosed with OSA after a night polysomnography recording between January 2014 and June 2014 consecutively. The subjects in the OSA group were divided according to the severity of the disease into three subgroups, consisting of 11 mild, 17 moderate OSA, and 22 severe OSA subjects. Twenty subjects with simple snoring were considered as the control group. RESULTS: We included a total of 70 subjects: 50 with OSA (11 subjects 6.9% mild, 17 subjects 24.7% moderate, and 22 subjects 68.5% severe) and 20 subjects with simple snoring as control cases. The mean age of the mild OSA subjects was 44.5 +/- 11.7 y, moderate OSA subjects' mean age was 52.5 +/- 11.9 y, and severe OSA subjects' mean age was 52.1 +/- 10.1 y; 54.2% were male. There were statistically significant differences among the 4 groups' OSI, TAC, and TOC levels, but there was no statistically significant difference between the other values. The mean myeloperoxidase, TOC, OSI, and TAC levels were 55 +/- 12, 61.2 +/- 21.1, 3.04 +/- 1.04, and 2.03 +/- 0.4 in the mild OSA group; 58.7 +/- 17.2, 60 +/- 18.9, 3.05 +/- 1, and 2 +/- 0.33 in the moderate OSA group; 56.6 +/- 17.9, 52.1 +/- 17.9, 2.7 +/- 0.76, and 1.94 +/- 0.24 in the severe OSA group; and 49.8 +/- 12.5, 54.3 +/- 16.4, 3.08 +/- 0.88, and 1.78 +/- 0.26 in the control group, respectively. CONCLUSIONS: In our study, there were no differences in studied parameters between control and OSA groups. Furthermore, our low number of cases was a restrictive factor. Further studies should be undertaken to clarify this relation.
The Relationships Among the Levels of Oxidative and Antioxidative Parameters, Fev1 and Prolidase Activity in Copd
(Taylor & Francis Ltd, 2017) Ekin, Selami; Arisoy, Ahmet; Gunbatar, Hulya; Sertogullarindan, Bunyamin; Sunnetcioglu, Aysel; Sezen, Hatice; Yildiz, Hanifi
Introduction: Chronic obstructive pulmonary disease (COPD) is a progressive condition characterized by poorly reversible airflow limitations associated with an abnormal inflammatory response of the lung. Methods: We investigated whether prolidase levels in serum, total antioxidant status, total oxidative status (TOS), and the oxidative stress index (OSI) were associated with the etiopathogenesis of COPD, and whether there is a relationship between prolidase activity and oxidative parameters and carotid artery intima-media thickness (CIMT) in patients with COPD. This study included 91 patients with COPD and 15 control cases. Routine haematological and biochemical parameters were determined in all patients. All subjects were fully informed about the study and provided consent. Results: The mean age of the patients with COPD was 61.3 +/- 10.5 years and that of the control group was 56.2 +/- 12.1 years. The control group had a significantly higher plasma prolidase level than that in the COPD group. TOS and OSI levels in the control group were significantly lower than those in the COPD group. However, no significant differences were found in TALs or CIMT levels between the COPD and control groups. A negative correlation was detected between prolidase activity and age; however, no significant difference in age was observed between the two groups. Conclusion: These results indicate that prolidase activity decreases in patients with COPD.
Yellow Nail Syndrome Presenting With Postpartum Massive Pleural Effusion
(Wiley-blackwell, 2014) Gunbatar, Hulya; Sertogullarindan, Bunyamin; Ekin, Selami; Arisoy, Ahmet; Ozkol, Hatice Uce
Yellow nail syndrome (YNS) is an uncommon clinical syndrome characterized by yellow-green discoloration of nails and recurrent respiratory tract lesions, pleural effusions and lymphedema. A 38-year-old woman was referred to the emergency complaining of chronic cough and increasing dyspnea within last 2 weeks. She had given birth 1 month ago. On examination, the patient exhibited dystrophic yellowish nails and mild peripheral lymphedema. A chest roentgenogram revealed a large right pleural effusion and a small left pleural effusion. YNS is a rare clinical entity but should be taken into consideration in patients with massive pleural effusions and persistent lymphedemas on the postpartum period.
