The Acute Effects of Thymoquinone on Acute Peripheral Nerve Injury: an Experimental Study
(Turkish Assoc Trauma Emergency Surgery, 2016) Gulsen, Ismail; Ak, Hakan; Kara, Mikail; Gokalp, Abdulsemat; Akyol, Veysel; Kocak, Omer Faruk; Ragbetli, Murat Cetin
BACKGROUND: The purpose of this study was to evaluate the acute effects of thymoquinone (TQ) on acute nerve injury. METHODS: A rat model of crush injury of the sciatic nerve was used. Animals were divided into 3 groups: control, trauma, and TQ treatment groups (n=6 per group). Seven days after injury, sciatic nerve specimens were obtained from the site of the injury and analyzed histologically and stereologically. Axon diameter, myelin thickness, and axon density were measured. RESULTS: There were no significant differences in axon diameter, myelin thickness, or axon density among groups. CONCLUSION: TQ has no acute therapeutic effect on acute nerve injury.
Comparison of Simultaneous Shunting To Delayed Shunting in Infants With Myelomeningocele in Terms of Shunt Infection Rate
(Turkish Neurosurgical Soc, 2011) Arslan, Mehmet; Eseoglu, Metehan; Gudu, Burhan Oral; Demir, Ismail; Kozan, Abdulbaki; Gokalp, Abdulsemat; Kiymaz, Nejmi
AIM: Timing of shunt insertion in infants with myelomeningocele (MM) and hydrocephalus (HCP) has been debated. Many authors have suggested to perform the repair of MM and shunt insertion during same operation. However, there is also an opposite view. MATERIAL and METHODS: We analyzed retrospectively 166 patients who underwent MM Sac repair to evaluate whether there are difference between these two methods in terms of shunt infection rate. RESULTS: In the same session,V-P (ventriculoperitoneal) shunt placement was performed onto 65 infants within the first 48 hours of postnatal and 36 infants were operated 48 hours after birth. In separate sessions, repair of MM were performed onto 29 infants within the first 48 hours of postnatal and shunting was peformed 7 days after sac repair. 14 infants were performed MM sac repair 48 hours after birth, then shunt was applied 7 days after closure of MM. Shunt infection rate in concurrently operated groups was markedly high (12.3 % in early surgery, 33.3% in late surgery); in separatedly operated groups' shunt infection rate was lower (3.44% in early surgery, 14.29% in late surgery). CONCLUSION: We propose to perform V-P shunt placement and MM repair in separate sessions.
Metastatic Myxoid Liposarcoma of the Scalp: Case Report
(Ortadogu Ad Pres & Publ Co, 2012) Kiymaz, Nejmi; Yilmaz, Nebi; Gudu, Burhan Oral; Demir, Ismail; Gokalp, Abdulsemat
Liposarcomas are the second most frequent soft tissue sarcomas occurring in adults after malignant fibrous histiocytomas; however, liposarcomas rarely occur on the scalp. A mass was detected on the hairy skin of a 38-year-old male patient who had undergone surgery for a mass on the posterior aspect of the right thigh and had been diagnosed with a myxoid liposarcoma 3 years earlier. The patient had undergone total bulk excision and the histopathologic examination of the mass lesion revealed liposarcoma metastasis. Chemotherapy was initiated. Relapse or metastasis did not develop during 3 years of follow-up. Here we present a patient with a myxoid liposarcoma, which metastasized from the posterior side of the right thigh to the scalp.
A Rare Extradural Mass: Primary Cervical Spinal Melanoma With Radiologic Findings
(Journal Neurological Sciences, 2014) Beyazal, Mehmet; Unal, Ozkan; Kankaya, Duygu; Bora, Aydin; Gokalp, Abdulsemat
Melanocytic cells are normally found in the meninges of the central nervous system (CNS). Primary tumour derived from meningeal melanocytic cells is rare. In this case report, a patient with primary spinal malignant melanoma localized in the cervical region was presented. Clinical features of this case including the magnetic resonance imaging (MRI) findings were described and its differential diagnosis was discussed with the line of literature.
