Öğe Associations of interleukin (IL)-1 beta, IL-1 receptor antagonist, and IL-10 with dental caries(Nihon Univ, School Dentistry, 2015) Cogulu, Dilsah; Onay, Huseyin; Ozdemir, Yasemin; Aslan, Gulcin I.; Özkınay, Ferda; Kutukculer, Necil; Eronat, CemalStreptococcus mutans is important in dental caries. Although the role of cytokines in the pathogenesis of dental caries is not clear, components of Streptococcus mutans were found to stimulate production of pro-inflammatory cytokines. We examined the associations of interleukin (IL)-1 beta, IL-1 receptor antagonist (IL-1ra), and IL-10 with dental caries. Unstimulated whole saliva and blood samples were obtained from 108 children aged 6-12 years with high caries (decayed, missing, or filled teeth [dmft/DMFT] index >4, n = 37), moderate caries (dmft/DMFT = 1-4, n = 37), or caries-free (dmft/DMFT = 0, n = 34). Streptococcus mutans level was classified as low (<10(5) colony-forming units [CFU]/mL) or high (>= 10(5) CFU/mL). Saliva and serum concentrations of IL-1 beta, IL-1ra, and IL-10 were determined by ELISA. IL-1 beta, IL-1ra and IL-10 gene polymorphisms were genotyped using PCR and restriction fragment length polymorphism analysis. The chi-square, Mann-Whitney U, one-way ANOVA, posthoc, Fisher's exact, and t tests were used in statistical analysis. Dental caries was not correlated with salivary or serum concentrations of the studied cytokines. Streptococcus mutans level positively correlated with saliva IL-1 beta concentration and inversely correlated with saliva IL-1ra concentration. There was no correlation of IL-1 beta, IL-1ra, or IL-10 gene polymorphisms with dental caries. Streptococcus mutans is important in stimulating saliva IL-1 beta and inhibiting IL-1ra. Future studies of associations between cytokines and dental caries should investigate additional cytokines and enroll a larger number of participants.Öğe Associations of interleukin (IL)-1 beta, IL-1 receptor antagonist, and IL-10 with dental caries(Nihon Univ, School Dentistry, 2015) Cogulu, Dilsah; Onay, Huseyin; Ozdemir, Yasemin; Aslan, Gulcin I.; Özkınay, Ferda; Kutukculer, Necil; Eronat, CemalStreptococcus mutans is important in dental caries.

These deformities may result in a connection between subarachnoid space and the middle ear resulting in recurrent episodes of meningitis. Additionally, it is commonly associated with hearing impairment. We describe here a boy with recurrent meningitis and unilateral sensorineural hearing loss. Mondini dysplasia was demonstrated with computed tomographic scans of the temporal bones in the search for pathogenesis of recurrent meningitis.Öğe A case of Mondini dysplasia with recurrent Streptococcus pneumoniae meningitis(Springer, 2009) Ciftdogan, Dilek Yilmaz; Bayram, Nuri; Ozdemir, Yasemin; Bayraktaroglu, Selen; Vardar, FadilMondini's dysplasia is a developmental anomaly of the middle ear characterized by cochlear malformation with dilation of the vestibular aquaduct, vestibule, and ampullar ends of the semicircular canals.

Forty-seven primary molars were classified as MExp or CExp according to the type of pulpal exposure. Pulp tissue was harvested and analyzed using enzyme-linked immunosorbent assay (ELISA). Subsequently, three pulpotomy agents calcium hydroxide (CH), mineral trioxide aggregate (MTA), and formocresol (FC)-were applied randomly, and the outcome was observed radiographically for 18 months. Levels of IL-6 and IL-8 were significantly higher in CExp pulp than in MExp pulp (P < 0.05). In the CH pulpotomy group, MExp teeth showed a higher success rate than CExp teeth. There was no significant difference in success rate between MExp and CExp teeth in both the FC and MTA groups. The levels of IL-6 and IL-8 have the potential to become indicators of pulp status and can be monitored by researchers to make the prognosis of vital pulp therapies less uncertain. As MTA and FC yielded higher rates of success than CH in CExp teeth, the choice of pulpotomy agent appears to be important in this context.Öğe Comparative evaluation of pro-inflammatory cytokine levels in pulpotomized primary molars(Nihon Univ, School Dentistry, 2015) Ozdemir, Yasemin; Kutukculer, Necil; Topaloglu-Ak, Asli; Kose, Timur; Eronat, CemalThe present in vivo study was performed to investigate the levels of the pro-inflammatory cytokines, interleukin (IL)-1 alpha, IL-6, and IL-8, in primary molars for which pulpotomy was clinically indicated, and to evaluate the success rates of three different pulpotomy agents employed for cariously (CExp) or mechanically exposed (MExp) primary molars.

Study design: A hundred and fifty children (75 males, 75 females, mean age: 10.19 +/- 1.61 years) were included in the study. The subjects were divided into three groups as high caries risk group (DMFT, dft>4)(n=55), moderate caries risk group (DMFT, dft=1-4)(n=57) and caries-free group (n=38). From each individual, blood samples were collected and DNA was extracted. The VDR gene was genotyped for the polymorphisms ApaI, FokI, Cdx2 and TaqI using polymerase chain reaction and restriction fragment length polymorphism methods. All data were analyzed by chi-square test, Fisher's exact test and t test. Results: There was statistically sign cant difference in the frequency of TaqI genotypes (tt) between caries-active and caries-free children (p=0.029). No statistically significant differences were detected between ApaI, FokI, Cdx2 genotypes and dental caries. Conclusion: In the future, VDR gene polymorphisms may be used as a marker for the identification of patients with high caries risk.Öğe A VERY RARE CAUSE OF CHILDHOOD PARAPARESIS PRIMARY INTRADURAL EXTRAMEDULLARY SPINAL HYDATID CYST(Lippincott Williams & Wilkins, 2009) Midyat, Levent; Gokce, Sule; Onder, Asan; Ozdemir, Yasemin; Mursalov, Gabil; Mir, SevgiHydatid disease is caused by the larval form of Echinococcus.
