    Inappropriate surgical interventions for midline fusion defects cause secondary tethered cord symptoms: Implications for natural history report of four cases
    (Springer Verlag, 2012) Selçuki M.; Umur A.Ş.; Duransoy Y.K.; Ozdemir S.; Selcuki D.
    Introduction The causes of tethered spinal cord are various. In order to release the tethering effect of these malformations, the surgical interventions must include removal of all tethering components, reconstruction of the neural tube and sectioning of tight filum terminale as well. Cases The cases reported in this paper have had an operation many years before for various developmental defects. After a certain period of time (5-10 years) of the first operation, the patients reapplied to the hospital with various symptoms of spinal cord tethering, either vertical or horizontal. Discussion At surgical intervention, it was noted that inappropriate surgical procedures caused retethering of the spinal cord in all patients. Postoperative period of all patients were uneventful. All patients declared relief in their symptoms. We would like to draw attention that untreated (or inappropriately treated) midline developmental defects will invariably cause syndrome of tethered cord. Consequently, prophylactic surgical untethering must be applied to all patients with developmental midline defects as soon as possible. Conclusion It looks that tethered cord symptoms invariably appear as enough negative influence accumulates as the time passes. Elapsed time may vary but unpleasant end result invariably arrives. While these cases with tethered spinal cord develop progressive neurological symptoms, prophylactic and appropriate surgical intervention should be considered as early as possible. There is no acceptable rationale to wait for the appearance of tethered cord syndrome symptoms to perform surgical untethering of the spinal cord because of the probability of irreversibility of the symptoms (incontinence of urine in particular) of tethered spinal cord syndrome. ©Springer-Verlag 2012.

    What should be the appropriate minimal duration for patient examination and evaluation in pulmonary outpatient clinics?
    (Wolters Kluwer Medknow Publications, 2017) Musellim B.; Borekci S.; Uzan G.; Ali Sak Z.; Ozdemir S.; Altinisik G.; Altunbey S.; Sen N.; Kilinc O.; Yorgancioglu A.
    Introduction: Patient examinations performed in a limited time period may lead to impairment in patient and physician relationship, defective and erroneous diagnosis, inappropriate prescriptions, less common use of preventive medicine practices, poor patient satisfaction, and increased violent acts against health-care staff. Objective: This study aimed to determine the appropriate minimal duration of patient examination in the pulmonary practice. Methods: A total of 49 researchers from ten different study groups of the Turkish Thoracic Society participated in the study. The researchers were asked to examine patients in an almost ideal manner, without time constraint under available conditions. Results: A total of 1680 patient examinations were reviewed. The mean duration of patient examination in ideal conditions was determined to be 20.4 ± 9.6 min. Among all steps of patient examination, the longest time was spent for 'taking medical history.' The total time spent for patient examination was statistically significantly longer in the university hospitals than in the governmental hospitals and training and research hospitals (P < 0.001). Among different patient categories, the patients with a chronic disorder presenting for the first time and were referred from primary or secondary to tertiary care for further evaluation have required the longest time for patient examination. Conclusion: According to our study, the appropriate minimal duration for patient examination is 20 min. It has been observed that in university hospitals and in patients with chronic pulmonary diseases, this duration has been increased to above 25 min. The durations in clinical practice should be planned accordingly. © 2017 Annals of Thoracic Medicine Published by Wolters Kluwer Medknow.

    Surgical outcomes of tethered cord syndrome in patients with normal conus medullaris and filum terminale without urologic symptoms
    (Springer Science and Business Media Deutschland GmbH, 2025) Tabanli A.; Akcay E.; Yilmaz H.; Ozdemir S.; Mete M.; Selcuki M.
    Purpose: Tethered cord syndrome (TCS) typically presents with urologic symptoms and abnormal imaging findings. However, some patients present with normal conus medullaris level and filum terminale appearance on MRI. This research seeks to assess the intended surgical results in this particular group of TCS patients who do not present with urologic complaints, under the premise that the surgical approach goes a long way in preventing the onset of urologic abnormalities. Methods: This retrospective study included 59 operated patients with tethered cord syndrome who had a normal level terminating conus medullaris and a normal looking filum terminale without urologic symptoms. Of these patients, 38 were female and 21 were male. All patients underwent somatosensory-evoked potentials (SSEPs), and magnetic resonance imaging (MRI). The surgical technique used was flavotomy, which involves cutting the filum terminale without performing a laminectomy. Results: The study population had a mean age of 22.5 years (SD = 13.2). During the mean postoperative follow-up period of 2.5 years, none of the patients developed urinary incontinence. Preoperative SSEP abnormalities included conduction block in 39 patients (66.1%), low amplitude in 12 patients (20.3%), and delayed N22 wave latency in 8 patients (13.5%). The surgical procedures were completed without morbidity or mortality, and all patients showed significant postoperative improvement in SSEP parameters. Conclusion: Our results indicate that even though the filum terminale might have a normal looking MRI, TCS can also occur due to some potential microscopic or structural abnormality. The study proves SSEP to be useful in TCS diagnosis and it also proposes that if surgery is done early before any urologic complaints arise, chances of their onset will be minimized. Such findings support the view that surgical measures should be entertained in symptomatic patients with abnormal SSEP but normal MRI. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.
