(Sage Publications Ltd, 2016) Suvak, Burak; Dulger, Ahmet Cumhur; Karadas, Sevdegul; Gonullu, Hayriye; Bayram, Yasemin; Gonullu, Edip; Guducuoglu, Huseyin
Objectives To determine the prevalence and determinants of acute pancreatitis in patients with acute brucellosis. Methods Adult patients with brucellosis were retrospectively recruited. Brucellosis and acute pancreatitis were diagnosed according to standard criteria. Laboratory analyses included Wright agglutination titre, serum biochemical parameters and blood count. Results Patients with acute pancreatitis (n=21) had significantly higher Wright agglutination titres, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, -glutamyl transpeptidase, amylase, lipase and serum glucose concentrations, and significantly lower haemoglobin concentrations and haematocrit than patients with brucellosis alone (n=326). Conclusions Hyperglycaemia, anaemia, and liver transaminase and cholestatic enzyme concentrations may represent new approaches for assessing disease severity in patients with brucellosis and acute pancreatitis.

(Carbone Editore, 2016) Arslan, Ayse; Tuzun, Fatma Aykan; Tamer, Sibel; Demir, Halit; Aycan, Abdurrahman; Demir, Canan; Gonullu, Edip
Introduction: Alzheimer's disease (AD) is a neurodegenerative disease characterized by progressive cognitive regression and memory loss. It has been claimed that oxidative stress and factors such as metal accumulation in the brain play important roles in the etiopathogenesis of the disease. Material and methods: The subjects of this study consisted of 24 individuals with Alzheimer's disease and 15 healthy agematched controls. Blood samples were withdrawn from the patients and healthy controls, and the activities of antioxidant enzymes SOD (Superoxide Dismutase), GSH (Glutathion), GSHPx (Glutathion peroxidase), GST (Glutathion S-Transferase) and MDA (Malondialdehyde) levels were determined by Spectrometer. Some metals and heavy metals were measured by atomic absorption spectrometry (AAS). Results: Biochemical analyses showed a significant decrease of the main enzymatic antioxidant defences (SOD, GSH, GST and GSHPx) and increased production of lipid peroxidation marker (MDA) in the serum of AD patients, compared to age-matched control group (p< 0.001). Also the levels of Zn, Mg, and Mn was lower and Fe, Pb, and Cd was higher in the patient group, compared to the control group. Serum Cu and Co levels did not differ significantly between the patient and control groups (p> 0.001). Conclusion: These results supports the theory that in AD there is a defect in the antioxidant defense system, which may lead to oxidative damage. Also alterations in some trace metals and their related enzymes may play a role of etiopathogenesis in AD.

(Termedia Publishing House Ltd, 2015) Suvak, Burak; Dulger, Ahmet Cumhur; Aykac, Mehmet Coskun; Gonullu, Hayriye; Gonullu, Edip
Introduction: Hepatitis delta virus (HDV) infection is a serious health problem worldwide. Thyroid disturbances represent a major limitation to the efficacy of interferon treatment targeting chronic HDV (C-HDV) infection. Moreover, pre-treatment thyroid diseases may be influenced by interferon therapy. Despite this, the characteristic features of the thyroid diseases in C-HDV patients remain poorly characterised. Aim: To determine the prevalence of thyroid diseases and evaluate the impact of delta hepatitis on thyroid function tests. Material and methods: We retrospectively reviewed the charts of 127 hepatitis C virus (HCV)-negative adults, treatment-naive outpatients with C-HDV, between July 2013 and July 2014. Thyroid-stimulating hormone (TSH) and thyroid antibodies (TAbs) including anti-thyroid peroxidase antibodies (anti-TPO), liver transaminases, and other routine laboratory tests were conducted during the study period. Results: A total of 127 C-HDV patients (female 52.9%, mean age 54.5 +/- 8.01 years) were enrolled. The rate of hypothyroidism, defined as a TSH level above 10 IU/l, was 4.7%. No patient had hyperthyroidism. Both elevated levels of liver transaminases and HDV ribonucleic acid (HDV-RNA) were positively correlated with high levels of thyroid autoantibodies. Conclusions: The rate of hypothyroidism is higher than the rate of hyperthyroidism at baseline. Most remarkably, for the first time we discovered a correlation between disturbed thyroid autoantibodies and elevated liver transaminases as well as high HDV-RNA levels even in euthyroid delta hepatitis patients. But in order to have an adequate understanding of such correlations, further studies are needed.
Does Heated Erythrocyte Suspension Transfusion With Medical Devices Containing Phthalates Increase Dehp and Mehp Levels
(Wiley, 2021) Gonullu, Edip; Bilvanisi, Sevdegul; Tasdogen, Aydin; Gonullu, Hayriye; Erkin, Yuksel; Kume, Tuncay; Aykac, Mehmet Coskun
Aims It is commonly known that stored blood and blood products are heated before transfusion to prevent hypothermia, which leads to increased di-(2-ethylhexyl) phthalate (DEHP) content leaching into the blood and blood products and thereby causes greater conversion of DEHP to mono (2-ethylhexyl) phthalate (MEHP). However, there has been no study in the literature reporting on the amount of toxic phthalates in blood following the erythrocyte suspension (ES) transfused via warming. In this study, we aimed to investigate the DEHP and MEHP content in blood following the heated ES transfusions administered by DEHP-containing and DEHP-free infusion sets. Methods The study included 30 patients that were randomly divided into two groups with 15 patients each: group I underwent ES transfusion via DEHP-containing infusion sets warmed with blood-fluid warmers, and group II underwent ES transfusion via DEHP-free infusion sets warmed with blood-fluid warmers. DEHP and MEHP levels were measured both before and after transfusion. Results DEHP-free infusion sets led to no increase in the phthalate content, whereas DEHP-containing infusion sets significantly increased the DEHP and MEHP, where the DEHP level increased almost four times (P = .001). Conclusion DEHP-containing products lead to toxicity. Therefore, using DEHP-free medical devices may prevent toxicity in patients undergoing ES transfusion.

(Termedia Publishing House Ltd, 2016) Dulger, Ahmet Cumhur; Suvak, Burak; Gonullu, Hayriye; Gonullu, Edip; Gultepe, Bilge; Aydin, Ibrahim; Olmezi, Sehmus
Introduction: Both hepatitis B virus (HBV) and hepatitis D virus (HDV) infection play an increasingly important role in liver diseases. The main objective of this study was to investigate the socio-epidemiological, laboratory and radiological aspects of both HBV and HDV infection near the Iranian border of Turkey. Material and methods: The study included 3352 patients with HBV and HDV infection. Socioepidemiological, laboratory and radiological aspects of the study subjects were retrospectively examined. Comorbid metabolic diseases were not assessed due to the retrospective design of the study. Results: Most of the study subjects were HBe antigen negative. No significant difference in terms of HBV-DNA levels or HBe antigen seropositivity was detected between the city centre and rural areas (p > 0.005). The mean HBV-DNA level in the anti-HDV-positive group was significantly lower than in the anti-HDV-negative group (p < 0.001). The rate of HDV-RNA positivity in women was higher than in their male counterparts (p = 0.017). Anti-HDV-IgG was detected in 18.4% of tested subjects who came from an urban area. In contrast, 12.5% of subjects of the rural group had a positive result for anti-HDV-IgG. Among 134 ultrasonographically evaluated delta hepatitis patients, 37.3% had liver cirrhosis. On the other hand, in 1244 patients with hepatitis B monoinfection, there were 90 patients with liver cirrhosis. Radiologically, the rate of hepatic steatosis in delta hepatitis patients was lower than in those with HBV monoinfection. Conclusions: Hepatitis D virus infection was particularly prevalent among the urban population as well as in female subjects. More broadly, the current observations are the first to suggest an inverse correlation between delta hepatitis and ultrasonography-proven hepatic steatosis.
Idiopathic Thoracic Spontaneous Spinal Epidural Hematoma
(Hindawi Ltd, 2016) Aycan, Abdurrahman; Ozdemir, Seymen; Arslan, Harun; Gonullu, Edip; BozkJna, Cemal
A 33-year-old male patient experienced temporary sensory loss and weakness in the right lower extremity one month prior to admission. The patient was admitted to a private clinic with a three-day history of acute onset of sensory loss and weakness in both lower extremities and was treated and followed up with a prediagnosis of transverse myelitis and the Guillain-Barre syndrome (GBS). The patient was subsequently transferred to our clinic and the neurologic examination revealed paraplegia in both lower extremities, positive bilateral Babinski signs, and hypesthesia below the T10 dermatome with saddle anesthesia. The patient had urinary incontinence and thoracic magnetic resonance imaging (MRI) showed an image of a mass compressing the medulla.

(Pakistan Medical Assoc, 2015) Gonullu, Hayriye; Gonullu, Edip; Karadas, Sevdegul; Arslan, Mehmet; Kalemci, Orhan; Aycan, Abdurrahman; Demir, Halit
Objective: To compare the levels of trace elements and heavy metal in patients with acute migraine and healthy controls. Methods: The prospective study was conducted at Yuzuncu Yil University, Turkey, from May to July 2013, and comprised migraine patients and an equal number of healthy controls. International Headache Society classification was used for diagnosing migraine. Serum copper, zinc, lead, iron, cadmium, cobalt, manganese, and magnesium levels were measured in both groups. Metal concentrations were assessed by atomic absorption spectrophotometry. SPSS 13 was used for statistical analysis. Results: There were 25 migraine patients with an average age of 36.4+/-8.9 years and 25 healthy controls with a mean age of 42.4+/-9.5 years. Cadmium, iron, manganese and lead levels were significantly elevated in the patients compared to the controls (p<0.05 each), while copper, magnesium and zinc were decreased and cobalt demonstrated no change. Conclusions: Trace elements and heavy metals may have a role in the genesis of considerable oxidative stress in patients with acute migraine headache.

(Elsevier Science inc, 2015) Aycan, Abdurrahman; Yener, Ulas; Aycan, Nur; Gonullu, Edip; Dursun, Recep; Gonullu, Hayriye
Background: On October 23, 2011, a devastating earthquake, magnitude 7.2 on the Richter Scale, jolted the province of Van in the east of Turkey and led to hundreds of casualties. Objectives: In this study, we aimed to present our clinical experience in the management of patients with cranial and spinal injuries who were admitted to the Van Regional Training and Research Hospital. Methods: The retrospective study included 44 (77.2%) patients who were referred to the neurosurgery department after being diagnosed with spinal and cranial injuries due to earthquake at the emergency department between October 23 and 27, 2011. Results: The patients comprised 32 male (72.7%) and 12 (27.3%) female patients with a mean age of 23.5 years. The injuries included scalp injury (n=16), burst fracture (n=7), compression fracture (n=3), epidural hematoma (n=9), subdural hematoma (n=3), contusion (n=1), traumatic subarachnoid hemorrhage (n=2), depressed skull fracture (n=3), linear fracture (n=9), cervical fracture (n=2), and pneumocephalus (n=1). Most of the patients (90.9%) had isolated injuries and the others (9.1%) presented with combined cranial and spinal injuries. At discharge, the 3 patients with spinal fractures were paraplegic, and of the 2 patients who were operatively treated due to subdural hematoma, 1 was hemiparesic and the other was hemiplegic. No mortality occurred in our patients. Conclusions: The results of this study demonstrated that, in the aftermath of a natural disaster, conducting correct triage procedures and performing a prompt intervention with appropriate and qualified equipment play key roles in reducing morbidity and mortality.

A New Approach in the Treatment of Traumatic Brain Injury: the Effects of Levosimendan on Necrosis, Apoptosis, and Oxidative Stress
(Elsevier Science inc, 2022) Aycan, Abdurrahman; Oksuz, Ersoy; Gonullu, Edip; Kume, Tuncay; Ergur, Bekir; Akyol, Mehmet Edip; Kuyumcu, Fetullah
- OBJECTIVE: Traumatic brain injury (TBI) is an essential and common health problem worldwide. Levosimendan is an inotropic and vasodilator drug used to treat heart failure. Moreover, it exerts pleiotropic effects and, thus, protective effects on many organs. The present study aimed to investigate the effect of levosimendan on necrosis, apoptosis, and reactive oxygen species in rats with TBI. - METHODS: The study included 28 female Wistar-Albino rats weighing 200-250 g. The rats were divided into 4 groups with 7 rats each as follows: Group 1: No trauma group (Control), Group 2: Traumatized, untreated group (T), Group 3: Levosimendan was administered at a dose of 12 mg/kg intraperitoneally 1 hour after the trauma (L1), Group 4: Levosimendan was administered at a dose of 12 mg/kg intraperitoneally 2 hours after the concussion (L2). After the experiment, the rats were decapitated, and the brain tissue was removed. Necrosis was assessed with Cresyl violet staining, apoptosis was assessed with immunohistochemical analysis, superoxide dismutase and catalase levels were measured with the spectrophotometric method, and malondialdehyde (MDA) levels were assessed by High-Performance Liquid Chromatography. - RESULTS: The number of necrotic cells in the L1 and L2 groups was significantly lower than in the K and T groups (P = 0.015 and P = 0.03, respectively). Although the active caspase-3 level was signified considerably in the T, L1, and L2 groups compared to the K group, no significant difference was found among these 3 groups (P > 0.05). The results of superoxide dismutase levels were similar to those of active caspase-3. catalase level was significantly higher in the K group than in the T and L2 groups (P = 0.045). Malondialdehyde activity was considerably higher in the L1 and L2 groups compared to the K group (P = 0.023). - CONCLUSIONS: Our results indicated that levosimendan may exert a neuroprotective effect by reducing necrosis in TBI and that levosimendan does not affect apoptosis and antioxidant levels in TBI. Comprehensive studies are needed to elucidate the effect of levosimendan on TBI fully.

(Journal Neurological Sciences, 2012) Gonullu, Edip; Silav, Gokalp; Kaya, Miktat; Arslan, Mehmet; Gonullu, Hayriye; Arslan, Harun; Demir, Halit
Aim: We aimed to determine the relationship both paraoxonase and prolidase activitys in the patients with malignant glioma. Methods: In this study, serum paraoxonase and prolidase activitys were measured on 25 healthy human and 25 patients with malignant glioma. Paraoxonase activity was measured using diethyl-p-nitrophenylphosphate as substrate, as previously described. The prolidase activity was used for measurement of proline by the method proposed by Myara et al., which is a modification of Chinard's method (Myara et al., 1982). Results: The paraoxonase and prolidase activitys were significantly lower in serum of patients with malignant glioma as a whole compared to controls. Conclusions: In the current study, the activity paraoxonase and prolidase decreased in the patients with malignant glioma. As a result the paraoxonase and prolidase decreased seems to play a major role in the pathophysiology of malignant glioma. This is the first report on serum paraoxonase and prolidase decreased activities in patients with malignant gliomas.

(Aves, 2017) Bozan, Nazim; Dinc, Mehmet Emre; Demir, Halit; Yalinkilic, Abdulaziz; Gonullu, Edip; Turan, Mahfuz; Kiroglu, Ahmet Faruk
OBJECTIVE: To determine the serum iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), magnesium (Mg), cobalt (Co), and lead (Pb) levels in patients with chronic otitis media (COM) and to evaluate the association of the serum levels of these elements with treatment outcomes. MATERIALS and METHODS: Thirty-one healthy volunteers and 31 patients with COM were prospectively included in this study. Serum levels of Fe, Zn, Mn, Mg, Cu, Co, and Pb were determined by an atomic absorption UNICAM-929 spectrophotometer. RESULTS: Serum Co, Pb, and Fe levels were significantly increased (p<0.001) and serum Cu, Zn, Mg, and Mn levels were significantly reduced in patients with COM compared with controls (p<0.001). Serum Co and Mn levels were significantly decreased (p<0.001 and p<0.005, respectively) and serum Cu levels were significantly increased after surgery (p<0.005). The other evaluated blood chemicals and heavy metals did not exhibit significant differences (p>0.05). CONCLUSION: Significant alterations in the serum chemical composition of patients with COM were observed. Moreover, with surgical treatment, serum levels of some of these chemicals were significantly altered. Further prospective studies are warranted to elucidate the exact association of these alterations in the etiopathogenesis of COM.

(derman Medical Publ, 2015) Gonullu, Hayriye; Gonullu, Edip; Soyoral, Lokman; Ozbay, Mehmet Fatih; Kaya, Yuksel
During general anesthesia and intensive care applications that require control of the airway respiratory, cardiovascular reflex responses occur thus myocardial oxygen delivery and consumption can be negatively affected. To prevent these effects, lidocaine, opioids, magnesium, calcium channel blockers, beta- blockers have been used. Local anesthetic toxicity; is usually known to occur when used over the range of safe dose of local anesthetics. It has been shown in a variety of animal and clinical studies that a lipid emulsion used for parenteral nutrition improves resistance to fatal cardiac effects caused by local anesthetics. Herein, we presented a case who had developed sudden bradycardia, asystole by iv. lidocaine which is used for tracheal intubation and improved dramatically after treatment with lipid emulsion in the light of the literatures. According to our knowledge it is the first case which is succesfully resuciatated with clinoleic in local anesthetic toxicity in literature.

(Tubitak Scientific & Technological Research Council Turkey, 2014) Yurtdas, Mustafa; Kaya, Yuksel; Gonullu, Edip
Background/aim: To document the safety, success, and complications of transradial coronary procedures. Materials and methods: This retrospective study consisted of 427 patients who had undergone transradial coronary angiography and/or angioplasty between June 2010 and May 2012. The main outcome measures were the procedural safety, success rate, and complications associated with transradial interventions. Results: Procedural success rate was 93.2% (398/427), with cannulation time of 2.1 +/- 1.4 min, diagnostic time of 5.6 +/- 2.1 min, fluoroscopy time of 9.5 +/- 6.6 min, and total procedure time of 47.1 +/- 20.2 min. The main causes for unsuccessful procedures were failed radial puncture (11 patients), serious radial artery spasm (12 patients), and distinct tortuosity (5 patients) and severe proximal stenosis (1 patient) of the right subclavian artery. Of 398 patients, 345 (86.7%) underwent both coronary angiography and angioplasty, while the remaining 53 (13.3%) had coronary angiography only. Major complication was recorded in only 1 patient (transient ischemic attack), whereas minor complications were observed in 76 patients (17 with symptomatic sinus bradycardia, 12 with venous thrombosis, 22 with hematoma, and 25 with radial artery occlusion). Conclusion: Our experience revealed that the transradial approach is a safe and feasible method for coronary procedures in patients with various manifestations of coronary disease.
