    Objectives: With the increasing rate of cesarean operations, the formation of niches and related early and late complications have been observed more frequently. In this study, we examined the effects of using a suture material that can be absorbed faster than conventional sutures on the formation of niches. Material and methods: This study was designed as a retrospective study and completed with a total of 101 patients. During the cesarean operation, the uterus was closed with Rapide Vicryl® in 49 patients and Vicryl® in 52 patients. The uterine niche was measured with a sonohysterogram 6 months after the operation. The primary outcome of the study was determined as uterine niche formation and the secondary outcome was the post-menstrual spotting (PMS) rate. Results: Duration of surgery, intraoperative/postoperative blood loss, and hospitalization time were similar between the two groups. Niche formation was significantly lower in the Rapide Vicryl group (22.4%) when compared to the Vicryl group (42.3%) (p = 0.046). Also, PMS was observed significantly lower in the Rapide Vicryl group (16.2% and 52.8% in Rapide Vicryl and Vicryl groups, respectively; p = 0.002). Conclusions: The formation of niches and associated PMS rates were less with suture materials that were absorbed faster

    This paper presents the first fabricated dual-band uncooled resistive infrared thermal microbolometer implemented with a resistive microbolometer and a tunable micro-mirror structure. Tunable reflective micro-mirrors are suspended underneath the suspended resistive microbolometers having a 35 mu m pixel pitch, and they are switched between two positions by the application of an electrostatic force for obtaining different responses in two wavelength infrared atmospheric windows, namely the 3-5 and 8-14 mu m, by tuning the optical tunable resonant cavity. This approach allows assessing the actual temperature of the viewed scene by comparing the responses of the detector in these two wavelength infrared atmospheric windows. The absorption coefficients of the detector are simulated by using the Cascaded Transmission Line (CTL) model, and the sacrificial layer thicknesses are optimized to obtain maximum absorption from these two wavelength regions. The absorption coefficients obtained from the measurements are in correspondence with the simulations. The responsivity measurements results shows that the absorption is decreased in an amount of 17.9 % in the 3-5 mu m spectral band, while the absorption is increased in an amount of 8.5 % in the 8-14 mu m spectral band, depending on the micro-mirror position. These initial results are promising for the dual-band detection using uncooled infrared microbolometer detectors

    Targeted Agents in Ovarian Carcinoma

    Gynecologic malignancies take an important part in female cancers. Ovarian cancer is the second most common gynecologic cancer with the highest mortality rate in developed countries. Most of the patients need an adjuvant chemotherapy regimen after the initial surgery. Despite their suppressive effect on tumor cells, much toxicity on healthy cells could be seen with these standard chemotherapeutics. In that manner a new way of tumor cell disruption with less toxicity and cancer selective effect is needed, which is called targeted therapy. Moreover this approach could prevent chemo-resistance and increase chemo-sensitivity of the disease. Primary cytoreductive surgery with platinum based chemotherapy shape the initial management of these tumors. However, recently we are on the edge of molecular therapy for this cancer. In this setting we need to identify a dominant biological pathway for tumor progression and discover a functional and structural molecule within this pathway. The new therapeutic modalities with targeted molecules should build up new perspectives insight tumor cell behaviour. Agents against angiogenesis and receptors of growth factors in addition to signalling cascades and intracellular enzymes could shape the individual treatment protocols for cancer survivors.

    Use of a combined retroperitoneoscopic and transperitoneal laparoscopic technique for the management of renal cell carcinoma with level I tumor thrombi

    Background: To report our initial experiences using a combined retroperitoneoscopic and transperitoneal laparoscopic technique for the management of renal cell carcinoma with level I tumor thrombi. Materials and Methods: Two patients underwent this technique for tumors 11- and 13-cm in diameter. After transection of the renal artery with limited mobilization of the kidney using a retroperitoneoscopic approach, additional ports were placed, and the management of the tumor thrombus was performed in the large working space provided by the transperitoneoscopic approach. Results: The technique was feasible in the present 2 cases. The total operative times were 170 and 200 min, respectively. The estimated blood loss was 450 cc in the first case and 200 cc in the second case. No complications were observed in either of the patients. Conclusions: Based on the initial clinical experience, we have presented a feasible surgical option for the laparoscopic management of renal cell carcinoma with level I thrombi

    Mucoepidermoid Carcinoma of Uterine Cervix: A Distinct Pathological and Clinical Entity

    Mucoepidermoid carcinoma of uterine cervix is a rare tumor that has some individual features. Defining risk factors after surgery shape the postoperative treatment modality on cervical cancer patients. Although there is not a well-known strategy for the postoperative follow-up of mucoepidermoid carcinoma, the aggressive behaviour of this tumor makes the gynecological oncologists choose liberal therapies on these patients
