    The effects of home oxygen therapy on energy metabolism in patients with COPD
    (Dove Medical Press Ltd, 2018) Berber, Nurcan Kirici; Yetkin, Ozkan; Kilic, Talat; Berber, Ilhami; Ozgel, Mehmet
    Background: COPD is preventable and treatable and is characterized by completely nonreversible airflow obstruction. In this study, we aimed to investigate the effect of long-term oxygen therapy on patients with stage 4 COPD who were followed up and treated at the polyclinic or clinic service. We evaluated the effects of oxygen therapy on energy metabolism and physical activity in patients with COPD. Methods: Nineteen patients with COPD (16 male/3 female), treated with oxygen therapy for the first time, were included in this study. Analysis of arterial blood gases and pulmonary function test was performed. Metabolic Holter device (SenseWear (R) Armband) was placed pre- and post-oxygen therapy on the patients' arm for at least 3 days. This device captures Holter data in a digitized electronic system, and the daily average value was calculated from the data. Results: Post-oxygen treatment showed a significant increase in energy expenditure by patients with COPD (pretreatment, 1,497 +/- 596 joule; posttreatment, 2,977 +/- 5,985 joule; P=0.044). Moreover, number of steps during walking (pretreatment, 2,056 +/- 256; posttreatment, 2,120 +/- 195; P=0.03), resting (pretreatment, 6.36 +/- 3.31 hours; posttreatment, 3.47 +/- 2.19 hours; P<0.03), and sleeping (pretreatment, 4.23 +/- 2.13 hours; posttreatment, 2.33 +/- 1.42 hours; P<0.00) showed significant differences. Increased daily energy expenditure in patients with respiratory failure was detected with long-term oxygen therapy. In addition, the immobility of patients decreased and duration of physical activity increased in patients with COPD. Conclusion: In this study, positive effects of long-term oxygen therapy have been demonstrated with respect to energy metabolism and physical activity of patients with COPD. Thus, we recommend that medication adherence and long-term oxygen therapy should begin early in patients with COPD.

    Is there a relationship between Haller Index and cardiopulmonary function in children with pectus excavatum?
    (Baycinar Medical Publ-Baycinar Tibbi Yayincilik, 2023) Katrancioglu, Ozgur; Ozgel, Mehmet; Inceoglu, Feyza; Katrancioglu, Nurkay; Sahin, Ekber
    Background: This study aims to systematically examine the cardiopulmonary functions in children with pectus excavatum and to compare the obtained findings with the Haller Index.Methods: Between September 2017 and June 2018, medical records of a total of 31 patients (27 males, 4 females; mean age: 14.8 & PLUSMN;2.0 years; range, 9 to 18 years) with pectus excavatum were retrospectively analyzed. The patients were divided into Group 1 (<2.5), Group 2 (2.5 to 3.19), and Group 3 (>3.2) according to the Haller Index. All groups were systematically evaluated based on pulmonary function tests and echocardiography. Forced vital capacity, forced expiratory volume in 1 second, and the forced expiratory volume in 1 second/ forced vital capacity ratio were calculated. Left ventricular end -diastolic diameter, ejection fraction, mitral valve prolapses, and right ventricular cavity in the apical four-chamber position were evaluated with echocardiography.Results: Of the patients, 19.4% were in Group 1, 38.7% in Group 2, and 41.9% in Group 3. The mean Haller Index value was 3.09 & PLUSMN;0.64. According to pulmonary function test results, 16.1% of the patients had restrictive disease and 6.5% had obstructive disease. There was a negative correlation between the index and forced expiratory volume in 1 second and forced vital capacity, and there was a statistically significant decrease in these values, as the Haller Index increased (p<0.017). There was a significant difference in the ejection fraction among the groups (p<0.001) and, as the Haller Index increased, ejection fraction statistically significantly decreased.Conclusion: Our study results show a negative correlation between the severity of pectus excavatum and pulmonary dysfunction and, as the severity increases, left ventricular function may be affected by the deformity. As a result, there seems to be a significant relationship between the severity of the deformity and cardiopulmonary functions.

    Pasteurella multocida Pneumonia with Hemoptysis in an Immunocompetent Case
    (Ankara Microbiology Soc, 2023) Benk Ugur, Isilay Gokce; Tanriverdi, Elif Seren; Ozgel, Mehmet
    Pasteurella species are gram-negative bacilli found in healthy pets' oropharynx and gastrointestinal tract flora. In humans, skin and soft tissue infections develop most frequently with the bite or scratching of animals such as cats or dogs. At the same time, they cause infections in the respiratory tract, mainly in patients with chronic lung disease or immunosuppressive patients. In this case report, a rare case of pneumonia caused by P.multocida bacteria in a patient with bronchiectasis was presented. A young male patient was admitted to the emergency department of our hospital with complaints of hemoptysis, cough with phlegm, and weight loss. The patient's blood pressure was 140/82 mmHg and SO2= 94%. Rales and rhonchi were detected in the lower left lung during the examination. Standard thorax tomography revealed prominent cystic structures and pneumonic infiltrates in the left lower lobe. Laboratory findings were normal. The Coronavirus disease-2019 (COVID-19) quantitative real-time polymerase chain reaction (qRt-PCR) test was found to be negative in the nasopharyngeal swab sample taken from the patient. Fiberoptic bronchoscopy was performed on the patient to investigate the presence of endobronchial lesion or foreign body aspiration. Culture and cytological evaluation was requested from the bronchial lavage taken. Gram-negative coccobacilli were seen among dense polymorphonuclear leukocytes in the Gram stain of the sample. Acid-fast bacilli were not detected with Ehrlich Ziehl Neelsen stain. In the lavage culture evaluated after 24 hours, colonies growing in blood and chocolate media were stained and gram negative coccobacilli were observed. The isolate was identified as 96.0% P.canis with the automated Vitek 2 (Biomerieux, France) system. It was determined that the isolate was susceptible to levofloxacin, trimethoprim-sulfamethoxazole, amoxicillin-clavulanic acid, penicillin, ciprofloxacin and cefotaxime in the antibiogram performed by disc diffusion test according to EUCAST v13.0 guideline criteria. Sequence analysis of the isolate obtained from the culture was performed on the ABI Prism 310 Genetic Analyzer (Applied Biosystems, USA). Sequence analysis of the isolate revealed 99.85% homology with P.multocida (GenBank accession no: NG_115137.1). Although Pasteurella multocida pneumonia is not commonly observed, the presence of underlying bronchiectasis in this patient facilitated the establishment of the bacteria. In order not to miss the diagnosis of pneumonia due to P.multocida, microbiological evaluation and molecular typing should be performed in the samples taken from the respiratory tract in patients with chronic respiratory diseases such as bronchiectasis.
