Öğe Cis-platinum combination chemotherapy during pregnancy for mucinous cystadenocarcinoma of the ovary. Case report(1999) Bayhan G.; Aban M.; Yayla M.; Gül T.; Yaldiz M.; Erden A.C.[No abstract available]Öğe Comparison of bupivacaine and bupivacaine with fentanyl in epidural analgesia during labour(1997) Tok D.; Ganidagli S.; Ozyilmaz M.A.; Turhanoglu S.; Yayla M.; Bayhan N.We have studied 50 healthy women who were in the first stage of labour and requesting epidural analgesia. They were allocated randomly in a double-blind fashion to receive either 15 cc 0.133% plain bupivacaine (group 1) 15 cc 0.133% plain bupivacaine + 100 ?g fentanyl (group 2) and when requested 15 cc 0.133% bupivacaine was given via the epidural route. Efficacy of analgesia was evaluated using linear visual analogue scoring (VAS) and verbal pain score (VPS). Maternal and fetal cardiovascular variables: maternal respiration rate (MRR) were measured continuously. The reduction in VAS and VPS was greater and the onset time of analgesia was shorter in group 2. Analgesia was associated with a reduction in arterial pressure in both groups but the haemodynamic alterations and the reduction in MRR were considered to be insignificant. Fetal heart rate didn't change side effects were insignificant and this study shows that epidural bupivacaine or bupivacaine + fentanyl combination provide effective analgesia and appeared to be safe for the mother and the child.Öğe Comparison of general and spinal anaesthesia in pregnant women with pregnancy induced hypertension(1999) Turhanoglu S.; Tok D.; Ozyilmaz M.A.; Bayhan N.; Olmez G.; Kaya S.; Yayla M.The technique of anaesthesia may become important when caeseraen section will be necessary instead of vaginal delivery in pregnant women with pregnancy induced hypertension. In our study, we compared general versus spinal anaesthesia in hypertensive pregnant women who had the same clinical conditions. Sixty pregnant women had taken to the study and allocated randomly into two groups. In the first group (n=30) general anaesthesia, and in second group (n=30) spinal anaesthesia were administered to the patients. Heart rate (HR), systolic arterial pressure (SAP) and diastolic arterial pressure (DAP) in the periods of pre, per (1., 3., 5. minutes and every 5 minute for thirty minutes) and postoperative (1., 30. and 60. minutes), APGAR scores at 1. and 5. minutes, uterine incision-cordon clamping time (Ui-Cc) and the time of first analgesic requirement in the postoperative period were recorded. The values of HR, SAP and DAP were significantly lower in the group of spinal anaesthesia (p<0.05). APGAR scores at the first minute were found significantly better in the group of spinal anaesthesia than the group of general anaesthesia (p<0.05). The times of first analgesic requirements were significantly shorter in the group of general anaesthesia (p<0.05). We concluded that spinal anaesthesia may be performed in preeclamptic women undergoing caeserean section with safe if the anaesthesiologist takes the necessary measures.Öğe Do cellular phones alter blood parameters and birth weight of rats?(2000) Daşdağ S.; Akdağ M.Z.; Ayyildiz O.; Demirtaş Ö.C.; Yayla M.; Sert C.The present study aimed to investigate the effects of microwaves (MW) emitted by cellular phones (CPs) on peripheral blood parameters and birth weights of rats. Thirty-six albino rats were divided into four groups, male (n = 6) and female sham-exposed groups (n = 12) and male (n = 6) and female experimental groups (n = 12). No blood parameters differed following exposure (p > 0.05). The birth weight of offspring in the experimental group was significantly lower than in the sham-exposed group (p < 0.001). No significant differences were observed between rectal temperatures of rats in the sham and experimental groups (p > 0.05). The specific absorption rate (SAR) was found to be 0.155 W/kg for the experimental groups. All parameters investigated were normal in the next generation of rats (p > 0.05).Öğe The effects of the microwave oven on pregnant and newborn rat kidneys(1997) Inaloz S.S.; Dasdag S.; Aslan A.; Bilici A.; Yayla M.Background: The increasing use of microwave radiation for industrial, scientific, medical and domestic purposes has resulted in growing concern about the biological effects of microwaves on man. Objectives: In this study, teratogenic effects of the microwave oven were investigated histologically on pregnant and newborn rat kidneys. Methods: Twenty-four pregnant Wistar- albino rats were separated into three groups (n=8), a control group (sham- exposed) and two experimental groups. The experimental gravid rats were confined in plexiglas cages which were placed next to the closed door of a microwave oven (power-output: 550W). In the first experimental group, the gravid rats were exposed to the microwave oven daily for 15 minutes whereas the gravid rats were exposed daily for 30 minutes in the second experimental group. Results: The physiological dilation of the renal tubules was observed in all dams. There was a positive correlation between the duration of exposure and the severity of necrosis. Necrosis of renal tubules together with normal glomeruli and stromal cells were seen in the first group of litters. Pronounced necrotic renal tissues and adrenal glands were observed only in the fitters of the second group. Conclusion: The teratogenic effects of the MW oven was observed especially in the second group of litters Nevertheless, pregnant users are not exposed to microwave radiation under the same conditions as in our experiment.
