    A Case of a New Syndrome or a Variant of the Rare Popliteal Pterygium Syndrome
    (2001) Öğün, T. C.; Tosun, Z.; Arazi, M.; Kapıcıoğlu, Safa
    The popliteal pterygium syndrome is very rare, and is characterized by a congenital popliteal web accompanying the genitourinary, craniofacial, and musculoskeletal anomalies. We described a case of presumably popliteal pterygium syndrome with severe right popliteal web, right renal agenesis, left bifurcated ninth rib, urethral orifice in the vagina, right presacral discoloration resembling A-V malformation, imperforate anus, skin dimple in the left gluteal region, right calcaneovalgus foot with supernumerary digits and aberrant profunda femoris artery. This is the first report of this combination in the pertinent literature.

    Cephalocaudal Variations in the Horizontal and Vertical Diameters of the Pedicles of the Lumbar Spine in the Turkish Population
    (2001) Öğün, T. C.; Üstün, M. E.; Büyükmumcu, M.
    Purpose: Racial morphometric differences in the pedicular structure of the vertebrae must be taken into account when using international transpedicular screw systems. In this study, we tried to figure out the differences, if any, in the size of the pedicles in a sample of the Turkish population. Methods: The horizontal and vertical diameters of the pedicles of the lumbar vertebrae were measured from the standardized anteroposterior radiographs of the lumbar spine in 100 subjects, aged from 20 to 40 years. Results: The mean horizontal width of the pedicles in our sample of the Turkish population was smaller than the subjects in other studies. The vertical diameter did not differ widely. There was a cephalocaudal increase in the horizontal diameters in both sexes. The vertical diameters did not increase. Significant differences between the pedicle diameters of the males and the females were noted at L2, L3 and L4 levels. No significant age-related variations were observed. Conclusion: Awareness of the racial variations in the size of the pedicles is very important when using international transpedicular screw systems. Preoperative determination of especially the horizontal diameter of the pedicles to be used for screw implantation from standardized anteroposterior X-rays is the easiest way.

    End-to-side Neurorrhaphy as a Salvage Procedure for Irreparable Nerve Injuries - Technical Note
    (Amer Assoc Neurological Surgeons, 2003) Öğün, T. C.; Özdemir, M.; Senaran, H.; Üstün, M. E.
    After a few reports on end-to-side nerve repair at the beginning of the last century, the technique was put aside until its recent reintroduction. The authors present their results in three patients with median nerve defects that were between 15 and 22 cm long and treated using end-to-side median-to-ulnar neurorrhaphy through an epineurial window. The follow-up times were between 32 and 38 months. Sensory evaluation involved superficial touch, pinprick, and two-point discrimination tests. Motor evaluation was completed by assessing the presence of opposition and by palpating the abductor pollicis brevis muscle. Sensory recovery was observed in all patients in the median nerve dermatome, and motor recovery was absent, except in Case 1. End-to-side nerve repair can be a viable alternative to nerve grafting in patients with long gaps between the ends of the injured nerve.

    Pain Following Spinal Cord Injury [spinal Kord Yaralanmalarinda Ağrı
    (2002) Levendoğlu, Funda; Öğün, C. Ö.; Öğün, T. C.
    Chronic pain is an important problem following spinal cord injury (SCI) with a prevelance around 65 %. One third of these people rate their pain as severe. A number of pain syndromes such as the transitional zone and central dysesthesia syndromes are associated with spinal injury based on the nature of the lesion, neurological structures damaged, and secondary pathophysiological changes. Accurate identification of pain types will help in selecting appropriate treatment approaches. Current pain treatment includes pharmacological approaches, surgical approaches, psychosocial modalities, electrical stimulation procedures, neurolytic injections, and physical modalities. But, results of these treatments are still controversial, Increased understanding of the pathogenesis of nociceptive, and neurogenic pain syndromes will enable clinicians develop effective therapies for these pain states that will improve the quality of life of patients with SCI.
