Objective: Autologous transfusion is frequently used with orthognathic surgery. The necessity of autologous transfusion has begun to question alone in bilateral sagittal split ramus osteotomy. The aim of this study was to evaluate the availability of autologous transfusion. Methods: The chart reviews of sixty patients who had undergone bilateral sagittal ramus osteotomy were done. The subjects were divided into two groups: In experimental group, 30 patients who autodonated 320ml in the preoperative 3 weeks actually received a transfusion in the postoperative 6 hours were included. In control group, 30 patients who underwent the same operation without preoperative donation and any other transfusion were included. Hemoglobin, hematocrit, and changes of these values in both groups were evaluated. Results: 1. From postoperative 3 hours to postoperative 1 day, the increases of hemoglobin(0.8g/dL in experimental group, 0.2g/dL in control group) and hematocrit(0.3% in experimental group, 0.6% in control group) were not statistically significant between both groups. 2. From postoperative 1 day to postoperative 1 week, the increase of hemoglobin(0.6g/dL in experimental group, 0.3g/dL in control group) was not statistically significant between both groups. But the increase of hematocrit(2.5% in experimental group, 1.0% in control group) was statistically significant between both groups over the same period(hematocrit p=0.043). 3. On postoperative 1 week, the values of hemoglobin(12.3% in both groups) and hematocrit(35.6% in experimental group, 36.8% in control group) were not statistically significant between both groups. Conclusion: The autologous transfusion in surgery of just a little blood loss was not effective. The most results show that there is little availability of autologous transfusion according to changes of hemoglobin and hematocrit in bilateral sagittal split ramus osteotomy.

Herein, we report a case of synchronous bilateral triple negative invasive ductal breast carcinoma in a patient with discrepant pathologic response to neoadjuvant chemotherapy. Right and left breast cancer stages at the initial diagnosis were T1cN0M0 and T4dN3aM0, respectively. The patient was identified as a BRCA1 mutation carrier and treated with four cycles of adriamycin and cyclophosphamide, followed by four cycles of docetaxel. Bilateral breast cancer stages decreased with the first regimen. However, the bilateral breast cancers showed discrepant responses to chemotherapy with docetaxel. The right breast cancer showed a continuous tumor volume reduction while the left breast cancer showed marked progression. Finally, the tumor size was 0.3 cm and 12 cm in the right and left mastectomy specimens, respectively. As bilateral breast cancers of the same subtype may show discrepant responses to neoadjuvant chemotherapy, close monitoring and follow-up imaging are required to avoid delayed surgery.

This study was undertaken to investigate the distribution of the chewing side preference and variations in the maximum bite force and facial morphology according to chewing side preference since unilateral chewing may cause morphologic and functional anomalies. 50 dental students who had no signs or symptoms of masticatory system and Angle's Class I relationship in posterior segments were selected, and divided into two groups, that is, 25 in bilateral chewing group(19 male and 6 female) and 25 in unilateral chewing group(10 male and 15 female). Maximum bite force was estimated ana posteroanterior cephalogram were measured ana statistically analyzed. The results were as follows : 1. Their were more students with bilateral chewing side preference($68\%$) and unilateral chewing side group consisted of right side preference($68\%$) and left side preference($32\%$). 2. There was no significant difference in the strength of max. bite force between the right and left side in bilateral chewing group. The bite force of the chewing side nab greater in the unilateral chewing group but less in the non-chewing side compared to those of bilateral chewing group with Bo significant difference. Max. bite force of chewing side was greater than that of non-chewing side in the unilateral chewing group(Female p<0.05). Max. bite force of males was about twice in that of females in both groups(p<0.05). Max. bite force of chewing side of the unilateral chewing group was similar to that of the bilateral chewing group, but that of non-chewing side was less than that of the bilateral chewing group. 3. In comparison of the facial morphology, there was no statistically significant difference in the size between the right and left side of the bilateral chewing group and between chewing and non-chewing side of the unilateral chewing group.

Objectives : The deficit of recognition memory has been found as one of the common neurocognitive impairments in patients with schizophrenia. In addition, they were reported to fail to enhance the memory about emotional stimuli. Previous studies have shown that bilateral eye movements enhance the memory retrieval. Therefore, this study was conducted in order to investigate the memory enhancement of bilaterally alternating eye movements in schizophrenic patients. Methods : Twenty one patients with schizophrenia participated in this study. The participants learned faces (angry or neutral faces), and then performed a recognition memory task in relation to the faces after bilateral eye movements and central fixation. Recognition accuracy, response bias, and mean response time to hits were compared and analysed. Two-way repeated measure analysis of variance was performed for statistical analysis. Results : There was a significant effect of bilateral eye movements condition in mean response time(F=5.812, p<0.05) and response bias(F=10.366, p<0.01). Statistically significant interaction effects were not observed between eye movement condition and face emotion type. Conclusions : Irrespective of the emotional difference of facial stimuli, recognition memory processing was more enhanced after bilateral eye movements in patients with schizophrenia. Further study will be needed to investigate the underlying neural mechanism of bilateral eye movements-induced memory enhancement in patients with schizophrenia.
