Anterior Stabilization Application With Odontoid Screw in a Patient With Type 2 Odontoid Fracture a Case Report
(Yuzuncu Yil Universitesi Tip Fakultesi, 2022) Taş, A.; Aycan, A.; Arabaci, O.; Yokuş, A.; Arslan, H.
The treatment of type II odontoid fractures has been discussed for many years. Due to the complex anatomy of the craniocervical junction, many-questions are encountered in the diagnosis and treatment of such fractures. However, in centers without Neuro-navigation and O-arm, free hand technique still remains a viable option for the surgical treatment of such cases. Although there is no neuronavigation and O-arm in our center, we will present our case of type II odontoid screw placement with free hand technique that we successfully applied in our elderly patient with a Type II fracture. © 2022, Yuzuncu Yil Universitesi Tip Fakultesi.

The Densities of Fiber Follicles in the Karakaş, Norduz, and Zom Sheep and a Comparative Analysis
(Universidad Austral de Chile, 2018) Tuncer, S.S.; Uslu, S.; Taş, A.; Şireli, H.D.
This study aimed to determine the densities of fiber follicles in the skin of the Karakaş, Norduz, and Zom sheep breeds and to carry out a comparative analysis between them. The study included a total of 36 animals aged 1-2 years and 3-4 years. Skin samples were obtained through biopsies taken from the right sides of the animals to determine the densities and ratios of the fleece follicles. Examination of these samples revealed that the primary follicle densities of the three sheep breeds (Karakaş, Norduz and Zom) were 3.11 ± 0.42, 3.14 ± 0.49 and 3.34 ± 0.59, while the secondary follicle densities were 8.42 ± 1.48, 8.51 ± 1.54 and 6.36 ± 1.44. The secondary to primary (S/P) follicle ratios of the sheep were 2.71 ± 0.70, 2.79 ± 0.69 and 1.85 ± 0.36, respectively. The primary follicle densities of the Karakaş, Norduz and Zom sheep were statistically similar for both age groups. The density of secondary follicles and S/P ratio decreased with age in both age groups. The similarity of the S/P ratios to those from other local sheep breeds suggest that Karakaş, Norduz, Zom sheep can be included in the sheep group that has coarse fleece. © Universidad Austral de Chile.

Effects of Age and Co-Morbidities on Complication Rate in Surgical Treatment of Lumbar Degenerative Diseases: a Prospective Clinical Study
(Yuzuncu Yil Universitesi Tip Fakultesi, 2023) Tufan, A.; Aktaş, Ö.Y.; Eren, B.; Doruk, E.; Gulec, I.; Taş, A.; Guzey, F.K.
Surgery for lumbar degenerative diseases is increasingly more common due to ageing of the population. There were conflicting results on effects of complication rates of ageing and presence of comorbidities in these o perations in literature. Presence of systemic co-morbidities, smoking, body mass index (BMI), American Society of Anaesthesiologists score, length of hospital before and after operation and in intensive care unit (ICU), number of decompressed levels (nD), addition of instrumentation, operation time, blood loss, presence of transfusion, surgical and systemic complications seen during the operation and during one month after operation, and requirement of a new operation were recorded in 277 patients (61.6±8.8 years of age, male/female ratio 78/199) operated for lumbar degenerative diseases between 2014 and 2016. Total 96 out of 277 patients (34.6%) had complications and 1 patient died. The most frequent complications were dural tear (36 cases, 12.9%), wound problems without infection (34 cases, 12.2%), screw malposition (15 cases, 5.4%), and systemic complications (21 cases, 7.5%). The risk factors were diabetes mellitus (DM) for major complications, BMI and nD for minor complications, and nD for systemic complications. All other factors including age did not affect the complication rate. Regression analyses revealed that the only efficient factor was BMI for presence of overall and minor complications. It was found that the advanced age did not cause to increase complication rates. The efficient factors for complication rates were DM, BMI and nD. © 2023, Yuzuncu Yil Universitesi Tip Fakultesi.

Effects of Stress Produced by Adrenocorticotropin (Acth) on Ecg and Some Blood Parameters in Vitamin C Treated and Non-Treated Chickens
(2006) Çinar, A.; Belge, F.; Donmez, N.; Taş, A.; Selçuk, M.; Tatar, M.
The aim of this study was to examine the effects of vitamin C on ECG and some blood parameters in chickens stressed by ACTH. Sixty Leghorn chickens were randomly allotted to control and experimental groups. Prior to the experimental period ECG's were recorded and blood samples were taken from both groups of chickens; some blood parameters were also determined. In the control group, isotonic sodium chloride solution was administered at a dose of 2.5 mL per chicken per day for a period of 5 days. In the experimental group, vitamin C (Redoxon Amp, Roche) was administered intramuscularly at the same dose (containing 250 mg vitamin C) and period of time. On the 5th day of the experiment chickens in both groups received 50 IU ACTH intramuscularly. Three hours following this application ECGs were recorded and blood samples were taken from both groups of chickens; some blood parameters were also determined. In conclusion, sinusoidal tachycardia was observed and an increase was determined (P<0.05) in the level of corticosterone and heterophil/lymphocytes (H/L) ratio after ACTH application in the control group.
Evaluation of Median Lethal Dose and Analgesic Activity of Foeniculum Vulgare Miller Essential Oil
(2006) Özbek, H.; Taş, A.; Özgökçe, F.; Selçuk, N.; Alp, Ş.; Karagöz, S.
Gas-chromatographic analysis, analgesic effect and median lethal dose (LD50) of Foeniculum vulgare Essential Oil (FEO) extract were investigated in mice. In all the experiments mice were tested twice, 30 min before drug administration in the baseline latency determinated and 30, 90 and 150 min after drug administration by tail-flick device. Aspirin (150 mg kg-1, peroral) and Morphine hydroclorure (10 mg kg-1 subcutan) were used as reference drugs. Only isotonic saline solution (0.2 mL, intraperitoneal) was given to the control group. 0.25 and 0.50 mL kg-1 FEO extract were given intra peritoneally to FEO groups. LD50 of the FEO was determined as 1.038 mL kg-1. At the 150th min of the study it is determined that all of the study groups (except Morphine group) had significantly analgesic effect when compared with control group and there was no difference between Aspirin and FEO groups. It was concluded that FEO had statistically significant and same analgesic effect with Aspirin showed at the 150th min of the study. © 2006 Asian Network for Scientific Information.
Povidone-Iodine Antisepsis in Lumbar Disc Surgery
(Yuzuncu Yil Universitesi Tip Fakultesi, 2022) Taş, A.; Aycan, N.; Aycan, A.; Zengin, İ.; Akyol, M.E.
Postoperative surgical sit e infection still constitutes a major concern in spinal surgery and related with poor outcome. We aimed to investigate the effect of povidone-iodine (PVP-I) on skin colonization in lumbar disc herniation (LDH) surgery. Adult patients scheduled for LDH surgery were included in the study. Three skin swab cultures were taken when lying on the operating table (culture 1), after PVP-I application (culture 2), and at the end of the operation (culture 3). The effect of PVP-I and other independent predictors on ski n culture was analyzed. A total of 62 [28 (45%) female, mean age 47±13 years] patients were included. Only male sex and taking shower before the surgery have been found to be independent factors for affecting culture 1 growth while adjusted to age, body ma ss index, smoking, preoperative hospital stay, and surgery site shaving [OR (95% CI): 7.8 (1.4-41.9), p=0.016; OR (95% CI): 0.34 (0.003-0.35), p=0.005]. After PVP-I, the growth frequency of culture 2 decreased significantly compared to culture 1 [8 (13%) vs. 43 (70%), p<0.001]. However, culture 3 positivity rate was similar to culture 2 (p=0.219). In preoperative sterilization of lumbar disc surgery, PVP-I significantly reduces skin colonization both immediately after application and at the end of the operation. © 2022, Yuzuncu Yil Universitesi Tip Fakultesi.

Short-Term Outcomes of Aneurysmatic/Non-aneurysmatic Patients Operated for Spontaneous Subarachnoid Hemorrhage: a Tertiary Referral Center
(Yuzuncu Yil Universitesi Tip Fakultesi, 2023) Aycan, A.; Taş, A.; Arslan, M.; Tufan, A.
We aimed to retrospectively analyze patients with aneurysmal dilatation and vascular malformation who presented with spontaneous SAH. Clinical data in patients files, Preoperative and postoperative neurological and radiological findings, age, gender, and treatment results were evaluated retrospectively. The same team performed surgery on 38 (47.5%) patients. Twenty (52.6%) of the patients included in the study were female, and 18 (47.3%) were male. There were 33 patients with detected bleeding aneurysms, three with bleeding AVMs, and two patients with non-bleeding aneurysms. It was determined that 5% of the patients had a Fisher score of 1, 34% had a Fis her score of 2, 24% had a Fisher score of 3, and 37% had a Fisher score of 4. Ten patients died. There were signs of vasospasm in 18 patients. Nine (50%) of 18 patients with vasospasm survived, and 9(50%) died. Eleven patients had hydrocephalus. EVD was in serted in 10 patients. Lamina terminalis was opened in 29 patients. The vessel with the most common aneurysm was the isolated AcomA aneurysm, with a rate of 31.5% (n=12). MCA aneurysm was found with the second frequency with a rate of 23.6% (n=9) Spontaneous subarachnoid hemorrhage is a disease with high mortality and morbidity in neurosurgery. Rebleeding, vasospasm, onset GCS, Fisher score, and experienced surgical equipment are among the factors affecting the treatment outcome. Multidisciplinary treatment in centers where diagnosis, treatment, and follow-up can be made by the same team will reduce mortality and morbidity rates. © 2023, Yuzuncu Yil Universitesi Tip Fakultesi.
