Item Ultra fast resolution of acute post-traumatic subdural haematoma(BMJ Publishing Group, 2005) Mirzai H.; Yaldiz C.; Eminoglu M.; Orguc S.[No abstract available]Item Evaluation of the effects of mobile phones on the neural tube development of chick embryos(Turkish Neurosurgical Society, 2013) Umur A.S.; Yaldiz C.; Bursali A.; Umur N.; Kara B.; Barutcuoglu M.; Vatansever S.; Selcuki D.; Selcuki M.Aim: The objective of this study is to examine the effects of radiation of mobile phones on developing neural tissue of chick embryos. Material and Methods: There were 4 study groups. All Groups were placed in equal distance, from the mobile phones. Serial sections were taken from each Group to study the neural tube segments. Results: The TUNEL results were statistically significant (p<0.001) at 30 and 48 hours in the third Group. We found low Bcl-2 levels partly in Group 4 and increased activity in Group 3. Caspase-3 was negative in the 48 and 72 hours in the Control Group, had moderate activity in the third Group 3, weak activity in the 48 hour, and was negative in the 72 hour in other groups. Caspase-9 immunoreactivity was weak in Group 1, 2 and 3 at 30 hours and was negative in Group 1 and 4 at 48 and 72 hours. Caspase-9 activity in the third Group was weak in all three stages. Conclusion: Electromagnetic radiation emitted by mobile phones caused developmental delay in chick embryos in early period. This finding suggests that the use of mobile phones by pregnant women may pose risks.Item Preoperative and postoperative evaluation of electromyography and magnetic resonance imaging findings in carpal tünnel syndrome; [Karpal Tünel Sendromunda Elektromiyografi ve Manyetik Rezonans Görüntüleme Bulgularının Preoperatif ve Postoperatif Değerlendirilmesi ](Ege University Press, 2014) Özkal B.; Yaldiz C.; Asil K.; Selçuki D.; Selçuki M.Introduction: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy caused by the compression of the median nerve in the carpal tunnel in the wrist. In the diagnosis of CTS, neurological examination and electrophysiological studies (EMG) findings are based primarily. This study was conducted in order to determine how effective magnetic resonance imaging examining in the diagnosis and follow-up of patients diagnosed with carpal tunnel syndrome is.; Material and methods: Our research was performed on 21 patients with 23 wrists diagnosed with CTS with clinical and electrophysiological tests. Magnetic resonance imaging (MRI) was performed preoperatively and postoperatively in 14.2 weeks for the hands of 21 patients in the anatomical prone position by using a wrist coil. The length and width measurements of the sections of the median nerve were proportionalized at three levels (length / width), and flattening ratio of the median nerve, median nerve area, the intensity of the median nerve were evaluated. All patients was operated by the same surgeon, neurolysis was not applied to any patient.; Results: When the results of the EMG before and after surgery of the study group were analyzed, it has been detected that, there was a significant improvement in motor conduction velocity and sensory conduction time compared to preoperative results. Hand / wrist MRI of the study group was compared with the control group, it has been observed that, the arithmetic mean of all measurements, except the ratio of carpal tunnel area / wrist area were greater than the control group. The differences in terms of median nerve flattening ratio in the middle and distal, the distal median nerve area, flexor retinaculum thickness, flexor retinaculum spring, the flexor retinaculum spring ratio were not significant.; Conclusion: Electrophysiological studies are the gold standard in the diagnosis of CTS. MRI is an effective method in the evaluation of patients after surgery. It may be used to reveal the cause of failed surgery. MR imaging is an effective method in the diagnosis of patients and in post-operative follow-up. © 2014 Ege University Press.

Many complications have been reported in literature for ventricular and peritoneal catheters and shunt valve. Spontaneous knotting of peritoneal catheter is an extremely rare condition. Mechanism of knotting is still unclear and peristaltism, elasticity of shunt materials, intraabdominal density, length of the peritoneal catheter and surgical technique may be responsible factors. In this paper, we presented a peritoneal catheter knotting resulted in shunt dysfunction in an 8-year-old girl. During surgery, we removed the peritoneal catheter, untied the knot and placed in the peritoneum again.Item Dermoid cyst rupture presenting as subarachnoid hemorrhage: Report of a rare case(Lippincott Williams and Wilkins, 2015) Yaldiz C.; Duransoy Y.K.; Mete M.; Şimsek T.; Işisaʇ A.; Selçuki M.Dermoid cysts are usually asymptomatic tumors and consist <0.5% of all primary intracranial tumors. Rupture of the cyst can occur spontaneously, due to head trauma or during the intraoperative or postoperative period. Although patients have been reported to be asymptomatic after cyst rupture, its etiology is not fully understood. Here, we present a 53-year-old male patient who was admitted to the emergency department with loss of consciousness following sudden onset of headache. He had a stiff neck on physical examination. Although complaints and findings suggested spontaneous subarachnoid hemorrhage, cranial computed tomography and magnetic resonance imaging demonstrated rupture of a dermoid cyst.
