    677C>T and 1298A>C Polymorphisms of Methylenetetrahydropholate Reductase Gene and Biochemical Parameters in Turkish Population with Spina Bifida Occulta
    (Turkish Neurosurgical Soc, 2010) Eser, Betul; Cosar, Murat; Eser, Olcay; Erdogan, Mujgan O.; Aslan, Adem; Yildiz, Handan; Boyaci, Gazi
    AIM: This study aimed to investigate the 677C>T and 1298A>C MTHFR gene polymorphisms and their metabolic effects on the levels of folate, vitamin B12 and homocysteine in the serum of Turkish spina bifida occulta (SBO) patients and healthy individuals in disease. MATERIAL and METHODS: A case-control study was performed to detect 677C>T and 1298A>C MTHFR gene polymorphisms in 39 SBO patients and 34 healthy individuals. The folate, vitamin B12 and homocysteine concentrations in the serum of SBO and healthy individuals were evaluated and compared with MTHFR gene polymorphisms. RESULTS: 677 CC/CT/TT MTHFR genotype frequency differences between the SBO patients and controls were not significant (x(2)=3.325, P=0.068; x(2)=1.479, P=0.224; x(2)=0.275, P=0.600; respectively). 1298A>C MTHFR genotype frequency differences between the SBO patients and controls were significant (x(2)=8.477, P=0.004). The frequencies of the A and C alleles of the 1298A>C polymorphism did not differ in a statistically significant manner between the groups (x(2)=0.576, P=0.448). The biochemical parameters were not significantly different between SBO patients and healthy individuals (P>0.05). CONCLUSION: The 677C>T and 1298A>C polymorphisms of the MTHFR gene cannot be regarded as major risk factors for SBO in the Turkish patients 677TT homozygosity may affect the metabolism of homocysteine.

    Intradiploic cavernous hemangioma of the skull in a child: a case report
    (Springer, 2008) Cosar, Murat; Eser, Olcay; Aslan, Adem; Korkmaz, Serhat; Boyaci, Gazi; Aktepe, Fatma
    Introduction Intradiploic cavernous hemangioma of the skull is seen rarely. Intradiploic cavernous hemangiomas arise from the intrinsic vasculature of the bone and generally picks up at the fourth and fifth decades. Discussion and conclusion In this report, we present a 16-year-old child who was admitted with a swelling lesion in the right parietal bone and diagnosed as cavernous hemangioma after total extirpation.

    Vertebral body pneumatocyst in the cervical spine and review of the literature
    (Turkish Neurosurgical Soc, 2008) Cosar, Murat; Eser, Olcay; Aslan, Adem; Korkmaz, Serhat; Boyaci, Gazi; Degirmenci, Bumin; Albayrak, Ramazan
    A pneumatocyst in the cervical spine is extremely rare and to our knowledge only a few reports have been published in the English literature. Although the etiology and natural course of vertebral body pneumatocyst is unclear, nitrogen gas accumulation is claimed. A 65-year-old-man was admitted to the emergency department with neck pain and numbness and incapacity in his both hands and fingers. The radiological images revealed a vertebral located pneumatocyst in the C4 cervical vertebra. In this report, we present a case of cervical pneumatocyst located in the C4 vertebral body. The clinical and radiological features and natural course of the pneurnatocyst were evaluated.
