    Evaluation of central and peripheral neuropathy in patients with chronic obstructive pulmonary disease
    (Dove Medical Press Ltd, 2018) Aras, Yesim Guzey; Aydemir, Yusuf; Doğan Güngen, Belma; Güngen, Adil Can
    Background: The aim of the study was to investigate the frequency and characteristics of peripheral nervous system (PNS) and central nervous system (CNS) involvement in COPD. Methods: The study included 41 COPD patients and 41 healthy volunteers. Electrophysiological studies were carried out: electromyography (EMG) and visual evoked potentials (VEPs). The median nerve, ulnar nerve, common peroneal nerve, and tibial nerve were evaluated for latency, amplitude, and conduction velocity. Results: The mean age of patients with COPD was 61.8 years and disease duration 10.3 years. There was no difference between patient and control groups in terms of age, BMI, smoking status, or biochemical parameters. Upon VEP examination, latencies were significantly prolonged and amplitudes shortened in the patient group compared to the control group. In EMG measurements, conduction velocity and amplitudes in all nerves were low in the patient group. Similarly, latencies in all nerves were higher in patients with COPD. Conclusion: Central and peripheral nervous system involvement could develop in patients with moderate-severe COPD, and these patients should be monitored for neuropathic changes in combination with neurological examination.

    A new marker in acute ischemic stroke patients: monocyte/hdl ratio
    (Duzce Univ, 2020) Alagöz, Aybala Neslihan; Acar, Bilgehan Atilgan; Doğan Güngen, Belma; Aras, Yeşim Güzey; Acar, Türkan
    Objective: Stroke is a major cause of global morbidity and mortality. Ischemic stroke is usually marked by cell death associated with inflammation and oxidative stress, and the role of inflammation in neurological diseases has become increasingly obvious. In our study, we studied the monocyte / HDL ratio (MHR) which can support the theory of inflammation in stroke and can be used in clinical practice. MHR can be used a prognostic marker in stroke patients base on this theory. Methods: Our study registered 91 acute ischemic stroke patients (47 females and 44 males) and 50 healthy controls. Results: MHR was elevated in the patient group and correlated with high-sensitivity C-reactive protein (hsCRP). MHR was higher in patients with high a National Institutes of Health Stroke Scale (NIHSS) than those with a low NIHSS (p=0.050) as well as in patients with a larger infarct area and in than those with a smaller area (p=0.050). The MHR correlated with both the clinical condition and infarct area in acute ischemic stroke patients, which underscores the value of MHR as a new marker. Conclusions: This cross-sectional study of 91 acute ischemic stroke patients indicates that inflammation markers and MHR are correlated with clinical status and even radiological parameters.

    Phenotypic and genotypic features of patients diagnosed with ALS in the city of Sakarya, Turkey
    (Springer Heidelberg, 2020) Kotan, Dilcan; Ayas, Zeynep Ozozen; Tunca, Ceren; Doğan Güngen, Belma; Akcimen, Fulya; Basak, A. Nazli
    Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease leading to motor neuron damage. In this study, the clinical, demographic, and genetic features of ALS patients in the city of Sakarya, Turkey, were investigated. Patients with an established diagnosis of ALS according to the Awaji criteria were included. Age, sex, age at onset of ALS, initial complaints, consanguineous marriage, and genetic features were retrospectively investigated. Conventional genetic analysis and NGS were used for molecular evaluation of patients. A total of 55 probands (10 familial, 45 sporadic) in whom ALS was suspected due to their phenotypic features were included. Thirty-two patients were male (58.2%), and 23 were female (41.8%); their mean ages were 62.65 +/- 13 years. The mean age of onset for 37 familial patients from 10 families was 49.9 years. Two cases had juvenile-onset. Fourteen (25.5%) bulbar-onset versus 40 (72.7%) limb-onset patients were detected; one patient had both. Six (10.9%) patients showed marked frontotemporal dementia. Twenty-nine (52.7%) patients died during the follow-up period. Genetic analysis identified causative variants in eleven cases, carrying variants in six different ALS genes (C9orf72,SOD1,VCP,SPG11,TBK1, and SH3TC2). Genetic investigations have revealed more than 40 genes to be involved in the pathogenesis of ALS. Our relatively small study cohort restricted to one province of Turkey, however, prone to migration, consists of 10/55 familial ALS cases, which harbor two rare (SH3TC2-p.Met523Thr and TBK1-p.Glu643del) and two novel (SPG11-p.Lys656Valfs*11 and VCP-p.Arg191Pro) mutations contributing to the literature.

    Pulmonary physiotherapy and aerobic exercise programs can improve cognitive functions and functional ability
    (Literatura Medica, 2018) Tekesin, Aysel; Tunc, Abdulkadir; Doğan Güngen, Belma; Avci, Nalan; Bakis, Muhammed; Perk, Seyma
    Objective - The increasing prevalence of dementia over the previous decades has been accompanied by numerous social and economic problems. The importance of exercise in the prevention of dementia coupled with the impact of aspiration pneumonia on the mortality and morbidity of dementia patients cannot be overstated. This study investigates the effects of pulmonary rehabilitation combined with aerobic stretching exercises on the cognitive function, life quality, effort capacity, and level of depression in patients with mild cognitive impairment (MCI) in the early stages of dementia. Methods - Sixty-nine patients with MCI diagnosis were routinely monitored, and six were excluded because they did not attend the follow-up appointments. The remaining 63 patients undertook pulmonary physiotherapy (PPT) and extremity exercises for six months. The mini-mental state examination (MMSE), six-minute walk test (6MWT), Nottingham health profile (NHP), and Beck depression inventory (BDI) scores were evaluated before and after exercise. Results - PPT plus extremity exercises appeared to significantly improve the MMSE scores and increase the 6MWT (p < 0.001) by an average of 25 m. No significant improvement was observed in the BDI and NHP scores. Conclusion - PPT and aerobic exercise positively affected the cognitive ability of MCI patients and improved their walking distance. These results underscore the importance of combining medical treatment with physical rehabilitation at the onset of dementia, a disease which exerts a significantly negative impact on the economy.

    Secukinumab in a patient with sarcoidosis
    (Taylor and Francis Ltd, 2020) Kobak, Şenol; Güngen, Adil Can; Doğan Güngen, Belma; Tutpınar, Yıldıray; Güler, Mehtap
    Sarcoidosis is a systemic granulomatous disease, characterized by non-caseating granuloma formation. It usually involves the lungs, but may also affect the eyes, heart, skin, and musculoskeletal system. The pathogenesis is not well known, but it is generally accepted as Th1 disease. The role of Th17-induced cytokines in the development of sarcoid granuloma has been reported.
