Öğe The effect of chronic carbon monoxide exposure on brain in Barbecue workers(Parlar Scientific Publications, 2014) Turtay M.G.; Yumrutepe S.; Kahraman A.S.; Bentli R.; Oguzturk H.; Firat C.; CoIak C.The aim of our study is to investigate whether chronic carbon monoxide (CO) exposure has effects on the brains of the people who work as barbecue workers (BWs) for a long time. Twenty males who had been working in the indoor environments of various restaurants (Group 1) and 20 healthy males who were matched by age with the other group (Group 2) were included in the study. Laboratory tests were performed in both groups of people. Magnetic Resonance Spectroscopy (MRS) was applied to the people whose blood samples were taken. In Group 1, significant correlations were not detected between carboxyhemoglobin (COHb) values and the variables of age, working hours, hemoglobin (Hb), white blood cell (WBC), hematocrit (HCT), platelet (PLT), mean platelet volume (MPV), pH, oxygen saturation (Sat 02) (p> 0.05). In terms of Hb, WBC, HCT, PLT, MPV, pH, Sat 02, COHb, N-acetylaspartate/creatine in basal ganglion, choline/creatine in basal ganglion, N-acetylaspartate/creatine in frontal lobe periventricular white matter, choline/creatine in frontal lobe periventricular white matter variables, significant differences between Group 1 and Group 2 were not determined. (p>0.05). As a result of this study; it is detected that chronic exposure to CO in BWs does not have any effects on brain with respect to MRS imaging method.Öğe The effect of the intercondylar notch width index on anterior cruciate ligament injuries: A study on groups with unilateral and bilateral ACL injury(ARSMB-KVBMG, 2015) Görmeli C.A.; Özdemir Z.; Kahraman A.S.; Yildirim O.; Görmeli G.; Öztürk B.Y.; Gözükara H.Background: To evaluate the relationship of the intercondylar notch width with unilateral and bilateral ACL injury by using MR images. Materials and Methods: The intercondylar notch width index was measured on the MR images of 18 patients with a bilateral ACL injury, 38 patients with a unilateral ACL injury and 53 healthy subjects with a normal ACL and the results of all groups were compared with each other. Results: The mean NWI values were 0,227 (± 0.008) in bilateral injured; 0,245 (± 0.009) in unilateral injured and 0,272 (± 0.01) in control groups and 0,251(± 0.01) in unaffected side of the unilateral group. There were statistically significant differences in intercondylar notch width index (NWI) values between all groups and there was a significant difference between the affected and the unaffected sides in group with unilateral ACL injury. A cutoff value of 0.25 for NWI gave an odds ratio of 26.5 for bilateral and 3.23 for unilateral ACL injuries. Conclusions: The finding that NWI is significantly narrowed in patients with bilateral and unilateral ACL tears compared with the healthy controls suggest a relationship between a narrow NWI and an increased risk of ACL injury. The patients with a narrow NWI should also be screened contralaterally for assessment of ACL injury risk on the other knee. So, specialized training programmes for the people with narrow NWI can be prepared for preventing ACL injuries. © 2015, Acta Orthopædica Belgica.Öğe Letter on the article "A rare tumour of the neck in a child"(Elsevier Masson s.r.l., 2017) Dogan M.; Kahraman A.S.; Yıldırım İ.O.[No abstract available]Öğe Transient renal medullary hyperechogenicity in newborns with acute renal failure and dehydration: Ultrasonography follow-up(2006) Çelik T.; Firat A.K.; Kahraman A.S.; Erdem G.; Karakaş H.M.; Yakinci C.Our purpose was to assess the time interval between the visualization of renal medullary hyperechogenicity and its resolution in neonates with acute renal failure. Seven newborns with renal medullary hyperechogenicity and acute renal insufficiency noted on ultrasonography (US) were included in the study group. Their ages were ranged between three and six days. All of the patients underwent US at the first presentation and in the follow-up. In all of the patients diffuse medullary hyperechogenicity was noted in the bilateral kidney. Biochemistry examinations revealed abnormal BUN and creatine level in all neonates and additional hypernatremia in four of them. The medullary hyperechogenicity totally disappeared between the 10th and 30 th days of the neonatal period. Renal functions had normalized before the resolution of medullary hyperechogenicity between the 7th and 10th days. Transient medullary hyperechogenicity may be delayed due to presence of abnormal renal functions. For this reason, while deciding to examine these patients for metabolic disease. persistent renal medullary hyperechogenicity after 10 days in the neonatal period should be evaluated in accordance with biochemistry findings.
