    Microincisional cataract surgery (MICS) with pulse and burst modes
    (Sage Publications, 2006) Baykara, Mehmet; Ercan, İ.; Özçetin, Hamit; Uludağ Üniversitesi/Tıp Fakültesi/Göz Hastalıkları Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/İstatistik Anabilim Dalı.; 0000-0002-2382-290X; ABI-7051-2020; 23093006700; 6603789069; 6603402155
    PURPOSE. To compare the amount of ultrasound (US) energy and balanced solution (BS) required for burst mode and pulse mode during bimanual phacoemulsification surgery. METHODS. One hundred cases were divided into two groups (the pulse mode Group 1 [50 eyes], the burst mode Group 2 [50 eyes]). One surgeon (M.B.) performed phacoemulsification procedures using topical anesthesia with the AMO Sovereign in all patients. The technique was based on the nuclear hardness and surgeon's criteria and performed bimanually. The surgery time, total ultrasound time (UST) and effective US power (USP), and used balanced solution (BS) were retrospectively compared. RESULTS. The mean surgery time, mean UST, and mean used BS volume were not statistically different in both groups (p > 0.05). The mean EPT was statistically highly different in both groups (p > 0.001). There was a slight tendency toward more surgery time in Group 2 than in Group 1, although the difference was not significant (p=0.146). Statistically significant higher results (Group 1: r=0, 889, p < 0.001 and Group 2: r=0, 834, p < 0.001) were seen in Group 1 when both groups were evaluated for the surgery time and used BS volume. When UST and used BS volume were evaluated in Groups 1 and 2, significant relation was seen in both but the correlation is statistically higher in Group 1 (Group 1: r=0, 765, p < 0.001, and Group 2: r=0,544, p < 0.001). CONCLUSIONS. The very low energy modes with the WhiteStar technology are suitable for bimanual cataract surgery.

    Nm23 expression in node-positive and node-negative endometrial cancer
    (Wiley, 2006-10) Yalçınkaya, Ülviye; Özuysal, S.; Bilgin, Tevfik; Ercan, İ.; Saraydaroğlu, Özlem; Demir, Davut; Uludağ Üniversitesi/Tıp Fakültesi/Patoloji Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Kadın Hastalıkları ve Doğum Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Biyoistatistik Anabilim Dalı.; 0000-0002-2382-290X; AAH-8924-2021; AAH-9701-2021; 6508300295; 56616314600; 7004103918; 6603789069; 15074395500; 34768054600
    Objective: To examine the relationships between the expression of protein Nm23 and surgical stage, histologic grade, histopathologic findings, and survival in women with endometrial carcinoma. Methods: 19 patients with lymph node involvement were matched with 24 patients without lymph node involvement and the best paraffin-embedded blocks were selected for Nm23 immunohistochemical staining. The slides were evaluated semiquantitatively according to their degree of cytoplasmic staining. Statistical analysis was performed to determine whether there was a relationship between Nm23 expression and surgical stage, histologic grade, depth of myometrial invasion, lymph node metastasis, and/or lymphovascular space involvement. Survival analysis was also performed. Results: Slides from 15 patients (79%) with lymph node involvement and 22 patients (88%) without lymph node involvement were found to be positive for Nm23 (P=0.01). No significant relations were observed between Nm23 expression and surgical stage, histologic grade, depth of myometrial invasion, or lymphovascular space involvement. Nm23 expression was found to be significantly related to lower rates of lymph node metastasis and longer survival (P=0.02). Conclusion: Elevated Nm23 expression is related to lower rates of lymph node metastasis and longer survival.
