    Clinical, pathological and radiological features of paraspinal textiloma: report of two cases and review of the literature
    (Termedia Publishing House Ltd, 2009) Hakan, Tayfun; Aydoseli, Aydin; Demir, Kemal; Aker, Fuegen
    Textiloma is a term Used for retained cottonoid or surgical sponge in the operation field. Although they occur mostly after thoracic or abdominal operation, they can also be encountered after surgery of extremities or the spine. There are few reports of spinal cases in which MR and CT imaging findings of textilomas have been described. In this report, two additional cases with MR, CT and pathological features of paraspinal textilomas are described. CT image demonstrated a paraspinal mass simulating a malignant tumour. While T1-weighted MR images showed the masses with low signal intensity, T2-weighted MR images showed heterogenous masses with low and high signal intensities.

    Impact of Herniorraphy Technique on Testicular Perfusion Results of a Prospective Study
    (Lippincott Williams & Wilkins, 2010) Koksal, Neset; Altinli, Ediz; Sumer, Aziz; Celik, Atilla; Onur, Ender; Demir, Kemal; Sumer, Hakan
    Background: Inguinal hernia repair is one of the most frequently performed operations. The Lichtenstein hernia repair is the most popular hernia repair technique in general surgical practice. However, totally extraperitoneal-preperitoneal hernia repair technique has been frequently used technique recently. The aim of this prospective, randomized, clinical study was to evaluate testicular perfusion after these 2 procedures. Methods: In our prospective randomized study, 32 male patients, aged 33 to 72 years who fulfilled the inclusion criteria underwent elective herniorraphy for groin hernia. The patients were randomly assigned into either Lichtenstein hernia repair (n = 16) or totally extraperitoneal-preperitoneal hernia repair (n = 16) group according to their admittance. Color Doppler ultrasonography of the testes was performed on all patients 1 day before the operation, 3 days and 6 months after the operation. Results: The results of the resistive index of the both groups; Lichtenstein hernia repair and totally extraperitoneal-preperitoneal hernia repair are statistically insignificant in all preoperative, early and late postoperative periods (P > 0.05). Conclusions: Either Lichtenstein hernia repair or totally extraperitoneal-preperitoneal hernia repair does not effect the testicular perfusion.

    The redundant nerve root syndrome of the cauda equina
    (Turkish Neurosurgical Soc, 2008) Hakan, Tayfun; Celikoglu, Erhan; Aydoseli, Aydin; Demir, Kemal
    The redundant nerve root syndrome is defined as the association of high-grade extradural lumbar spinal stenosis with large, elongated and tortuous nerve roots. Acquired elongation of nerve roots due to the mechanical trapping at the level of lumbar spinal stenosis is assumed to be the possible mechanism. It is believed that the cause is a squeezing force due to the chronic compression. The most common clinical symptoms are low back pain and leg pain. Although lumbar spinal canal stenosis is common, the entity has rarely been discussed in the literature. Here we present the MR imaging and intraoperative appearance of the condition with a brief discussion in a 71-year-old woman.

    The relationship between magnetic resonance Imaging findings and postural Maneuver and physical examination tests in patients with thoracic outlet syndrome: Results of a double-blind, controlled study
    (W B Saunders Co-Elsevier Inc, 2007) Demirbag, Derya; Unlu, Ercument; Ozdemir, Ferda; Genchellac, Hakan; Temizoz, Osman; Ozdemir, Huseyin; Demir, Kemal
    Objectives: To investigate the differences in findings from magnetic resonance imaging (MRI) in the neutral and provocative positions, and to examine the relationship between these differences and the results of physical examination tests in patients with thoracic outlet syndrome (TOS). Design: Prospective. Setting: University physical medicine and rehabilitation outpatient and radiology clinics. Participants: Twenty-nine patients and 12 healthy controls. All of the patients had positive bilateral TOS stress tests; control group participants were symptom free and had negative TOS stress tests bilaterally. Interventions: Not applicable. Main Outcome Measures: All participants underwent Adson's test, the Halsted maneuver, and a hyperabduction test. All were evaluated with MRI while in 2 positions: the neutral position (upper extremities adducted) and in a provocative position. Measurements were obtained at the interscalene triangle, at the costoclavicular space, and at the retropectoralis minor space. Results: There was a significant difference in MRI findings between the neutral and provocative position in the patient (P<.05), but there were no significant differences in the control group. There was a significant difference in the positional change values in MRI between the patients and the control subjects (P<.05). The difference was found in the minimum costoclavicular distance between patients with a positive Halsted maneuver and a negative Halsted maneuver (P<.05). Conclusions: Our findings indicate that MRI findings in patients in a provocative position are more valuable in the diagnosis of TOS, and these findings are in accord with findings from the physical evaluation tests.
