Objective: We experienced a case with recurring constipation and diarrhea caused by morphine for relieving cancer pain, who were well managed with oral administration of misoprostol. Subject: The patient was a male in his 70s with recurrent bladder cancer following primary surgery, developed bone metastasis to right side pelvis and exhibited cancer-related pain. To alleviate the resting pain, he underwent radiotherapy and received a sustained preparation of morphine sulfate, that lead to difficulty in bowel movements (repeated constipation and diarrhea) and abdominal distension which was intractable with routine administration of laxatives. Misoprostol, a prostaglandin E1 derivatives, which was reported to have an ability to control the bowel movement was administered at a dose of 800μg/day, and the patient subsequently achieved the improvement of bowel dysfunction and resumed regular self-defecation. Discussion: Misoprostol do not only accelerate small intestine movement but also inhibits water and sodium absorption. In this case, it is suggested that the pharmacological properties of misoprostol enabled to improve bowel movement. We consider that misoprostol is useful as one of the medications for refractory constipation caused by opioid administration. Palliat Care Res 2008:3(1);301-304

Purpose: The effectiveness of a flow chart of medication for cancer pain treatment was investigated. This flow chart was developed at Sasebo Chuo Hospital, and calls for the early introduction of controlled-release oxycodone tablets in combination with prescribing of a rescue dose and agents to prevent adverse reactions such as nausea, vomiting, and constipation. Method: The flow chart was used with a group of 29 patients (FC group), but not with a group of 35 patients (non-FC group). The rate of titration, which was adjustment of opioid dosage to achieve cancer pain control, and time required to achieve titration were compared between these two groups. Results: The titration rate of the FC group was 93.1% and that of the non-FC group was 80.0%. Medication was changed to another opioid for 4 patients in the non-FC group because of nausea and vomiting. The time required to achieve titration was 3.8±2.2 days in the FC group and 5.3±3.0 days in the non-FC group, and a significant difference was noted (p=0.048). Conclusion: The use of this flow chart with its early introduction of opioid controlled-release oxycodone tablets appears to be effective in achieving cancer pain control at an early stage.

BACKGROUND: Most cases of facial asymmetry involve yaw deformity, and determination of the yaw correction level is very difficult. METHODS: We use three-dimensional soft tissue simulation to determine the yaw correction level. This three-dimensional simulation is based on the addition of cephalometric prediction to gradual yaw correction. Optimal yaw correction is determined visually, and an intermediate splint is fabricated with computer-aided design and computer-aided manufacturing. Application of positioning devices and the performance of horseshoe osteotomy are advisable. RESULTS: With this procedure, accurate repositioning of jaws was confirmed and patients obtained fairly good facial contour. CONCLUSIONS: This procedure is a promising method for a widespread, predictable treatment of facial asymmetry.

Safe introduction of laparoscopic partial liver resection (LPLR) requires the selection of appropriate cases not exceeding the surgeon's skills as well as standardization of surgical procedures. After introduction at our institution, 60 LPLR procedures were performed between April 2010 and May 2016. To identify indices for case selection, short-term perioperative parameters were analyzed, including operative time, blood loss, postoperative complications, and postoperative hospital stay. Operative time was significantly shorter in the last 30 cases compared with the first 30 cases (182.5 min vs. 253 min; p=0.023) and in 16 cases involving the left lobe (S2-4) compared with 44 cases involving the right lobe (S1, S5-8; 148.5 min vs. 246 min; p=0.004). Blood loss was significantly less (0 mL vs. 50 mL; p=0.028) and operative time was significantly shorter (185 min vs. 250 min; p=0.048) in 27 cases with tumor diameter <2.5 cm compared with 33 cases with tumor diameter ≥ 2.5 cm. Operative time tended to be longer in 9 cases of multiple-site resection compared with 51 cases of single-site resection (207 min vs. 260 min; p=0.085). BMI, pathology, and hepatitis virus status showed no significant difference in perioperative short-term results. For the introduction of LPLR, it may be preferable to select cases located in the left lobe with a tumor diameter <2.5 cm and to accumulate a certain amount of experience in similar cases first.

BACKGROUND:
The current study aimed to investigate the hepatoprotective effects of Sasa veitchii extract (SE) on carbon tetrachloride (CCl)-induced liver fibrosis in mice.
METHODS:
Male C57BL/6J mice were intraperitoneally injected with CCl dissolved in olive oil (1 g/kg) twice per week for 8 weeks. SE (0.1 mL) was administered orally once per day throughout the study, and body weight was measured weekly. Seventy-two hours after the final CCl injection, mice were euthanized and plasma samples were collected. The liver and kidneys were collected and weighed.
RESULTS:
CCl administration increased liver weight, decreased body weight, elevated plasma alanine aminotransferase, and aspartate aminotransferase and increased liver oxidative stress (malondialdehyde and glutathione). These increases were attenuated by SE treatment. Overexpression of tumor necrosis factor-α was also reversed following SE treatment. Furthermore, CCl-induced increases in α-smooth muscle actin, a marker for hepatic fibrosis, were attenuated in mice treated with SE. Moreover, SE inhibited CCl-induced nuclear translocation of hepatic nuclear factor kappa B (NF-κB) p65 and phosphorylation of mitogen-activated protein kinase (MAPK).
CONCLUSION
These results suggested that SE prevented CCl-induced hepatic fibrosis by inhibiting the MAPK and NF-κB signaling pathways.
