Abstract
Malignant mixed müllerian tumor (MMMT) is a rare tumor in females and extragenital MMMT is even more so. We report a patient with MMMT primarily in the mesentery with synchronous ovarian cancer. In the English literature, 42 cases of extragenital MMMT have been reported other than the presented case, and this is only the second MMMT arising from the mesentery. Furthermore, among the cases reviewed, MMMTs tend to be associated with synchronous or metachronous colonic cancer or gynecologic tumors originating from the müllerian duct, including ovarian tumors, fallopian tube cancer, endometrial cancer, cervical cancer, and serous carcinoma of the peritoneum (14 out of 43 patients; 32.6%). The risk factors for MMMT include obesity, nulliparity, exogenous estrogen, and long-term tamoxifen use. The prognosis of MMMT is catastrophic and the treatment is based on the experience of those of uterine sarcomas, which is composed of operation, radiotherapy and chemotherapy.

Abstract
We compared four different skin surface landmarks, the lower margin of the right 2nd costo-sternal junction (point A); the upper margin of the right 3rd costo-sternal junction (point B); the lower margin of the right 3rd costo-sternal junction (point C); and a point 5 cm below the manubrio-sternal junction (point D), in 20 cancer patients undergoing insertion of permanent central venous catheters whose tips were placed near the superior vena cava - right atrium (SVC-RA) junction under transoesophageal echocardiography guidance. The landmark was satisfactory if it was located within 1 cm of the SVC-RA junction. Points C and D were closer to the SVC-RA junction than points A and B (p < 0.0001). However, point C had the highest incidence (C: 70%, A: 0%, B: 20%, D: 30%, p < 0.0001) of being within 1 cm of the SVC-RA junction.

Abstract
We describe an unusual case of tumour lysis syndrome in a child with a high-grade lymphoma undergoing a staging laparotomy. The patient presented with a refractory ventricular arrhythmia, which required continuous resuscitation in the operating room and continuous venous-venous haemodialysis in the intensive care unit. This case report suggests that surgery is a possible trigger for developing tumour lysis syndrome, so anaesthetists should be alert to this possibility during surgery in patients with pre-existing high tumour burdens.

Abstract
A prospective study comparing the efficacy of wire-conducted intravascular ECG (IVECG) signal and signal from the port with a sodium bicarbonate (NaHCO3) flushed catheter to correctly place a catheter tip was carried out in 100 patients. The correct position of the catheter tip was confirmed as follows: with technique G, the IVECG signal was conducted from a guide wire to identify the tip position. With technique P, the IVECG signal was conducted from the port with a NaHCO3 (0.8 mmol/ml) flushed catheter to ascertain the tip position. Each patient received both technique G and technique P in a randomized sequence. The quality of IV-ECG signals, which included baseline drift, P wave pattern and QRS wave pattern, were assessed for ten seconds. Satisfactory quality of these IVECG signals was observed in all of the patients with technique P and 90 of the 100 patients with technique G, and this difference was significant (P=0.001). There was no obvious difference between the techniques in catheter tip placement time or the measured optimal catheter length. The incidence of atrial premature contractions was higher with technique G than with technique P (13% vs 2%; P=0.003). Therefore, technique P is a practical alternative for correctly placing the catheter tip of a Port-A-Cath.

Abstract
Bone morphogenetic proteins (BMPs) have been shown to play an important role in cell growth and differentiation. BMPs, a rapidly expanding family closely related to transforming growth factor-beta (TGF-beta) superfamily, have been proven recently to possess a regulatory role and neurotrophic capacity in neurogenesis. The aim of the present study is to reveal the relationship among BMPs, peripheral nerve and neoplastic lesions of nerve sheath tumors. The mRNA transcriptions of BMP 2, 3, 4 and 5 in 12 cases of schwannoma, four cases of malignant schwannoma and three cases of trigeminal neuralgia were detected using an in situ hybridization technique. Our results demonstrated that the myelin sheaths of schwann cell from the peripheral neuroectomy of trigeminal neuralgia were positively expressing mRNA of BMP-2, 3, 4 and 5. However, the nerve fibers of trigeminal nerve showed only BMP-2 positive staining. All of the neoplastic lesions of nerve sheath showed a consistent but variant expression of BMP-2, 3, 4, and 5. Except for the BMP-4 mRNA, the expression signals of BMP-2, 3 and 5 mRNA in malignant schwannoma were relatively lower than in benign lesions. On the basis of the findings, we concluded that selected members of BMPs existed in the peripheral nerves and might contribute to the health maintenance, proliferation, regeneration and neoplastic transformation of the peripheral nerve system. Moreover, the effects of BMP-2, 3, 4 and 5 on peripheral nerve system and its neoplastic transformation might be widespread, diverse and antagonistic.

Abstract
A 56-yr-old, 58-kg woman with right femoral neck fracture underwent right bipolar hemiarthroplasty. Her medical problems included diabetes mellitus and multiple myeloma. Epidural anesthesia was performed uneventfully. No other drug except for local anesthetic (2% lidocaine) was administered during the procedure. Unfortunately, we "witnessed" the dramatically hemodynamic change of an intraoperative stroke, which was preceded by a hypotensive episode and followed by sustained hypertension. The stroke was presented with decreased level of consciousness initially and confirmed by the brain CT, which revealed acute infarction at the right middle cerebral artery territory, four days after the procedure. Multiple mechanisms such as intraoperative hypotensive episode and vascular atherosclerotic change due to poor controlled diabetes mellitus might be involved in the event. In the meanwhile, hyperviscosity (3.7 centipoise units of the patient v.s. 1.4-1.8 centipoise units of normal range) caused by multiple myeloma might also have contributed to the intraoperative stroke. Clinical presentation of this case will be discussed.

Abstract
Intravenous electrocardiograph (IVECG) can correctly positioning the catheter tip by enlarging p wave as it is moved toward right atrium, and it is a safe, reliable and accurate technique. To evaluate the efficacy of wire-conducted IVECG signal and IVECG signal from the port with sodium bicarbonate (NaHCO3) flushed catheter and to compare those with conventional anatomy landmark method was the propose of this study. This prospective study was carried out in 216 patients who suffered from malignant diseases. The correct position of the catheter tip among these groups was confirmed as follows. In group 1 (n = 80), the anatomy landmark method and portable chest radiograph recognized the correct position. In group 2 (n = 72), IVECG signal was conducted from guide wire to identify the tip position. In group 3 (n = 64), IVECG signal was conducted from the port with NaHCO3 (0.8 mEq/mL) flushed catheter to ascertain the tip position. The patient characteristics did not differ significantly among the groups. The duration of operation was significantly (P < 0.001) longer in group 1 than in group 2 and group 3 (45.4 +/- 9.3 minutes vs 35.7 +/- 8.0 minutes and 35.2 +/- 9.7 minutes, respectively). Catheter tip placement times were shorter in group 2 and group 3 than in group 1 (5.3 +/- 2.9 minutes and 6.4 +/- 3.0 minutes vs 16.7 +/- 5.7 minutes, respectively); there was a statistically significant difference between the group 1 and group 2 and group 3 (p < 0.001). Nonetheless, the duration of operation and catheter tip placement time was similar in group 2 and group 3. Early and late complications within the subsequent 3 months showed no significant difference among groups. We concluded that IVECG signal conducted from guide wire obtained a similar efficiency to that signal from the port with NaHCO3 flushed catheter on positioning the catheter tip of the venous Port-A-Cath system. It is recommended to use these methods to facilitate implanting long-term central venous devices.

Abstract
Laparoscopy can be performed while patients are under total intravenous anesthesia (TIVA), or sedated and breathing spontaneously through the normal airway. Respiratory monitoring is difficult when patients are sedated or anesthetized, however. The purposes of this study were to evaluate the reliability of end-tidal carbon dioxide (ETCO2) measurement for monitoring arterial carbon dioxide pressure (PaCO2), and to assess the PaCO2/ETCO2 gradient among patients receiving TIVA while breathing spontaneously through the normal airway. Sixty patients were divided into two groups: group 1 patients (n = 30) received general anesthesia with controlled ventilation, while group 2 patients (n = 30) received TIVA with spontaneous breathing through the normal airway; ETCO2 was sampled through a 10-French suction catheter inserted into the nasopharynx via the nasal airway. Arterial blood gas and ETCO2 were recorded at the time of preinduction, induction, CO2 insufflation, and change to Trendelenburg tilt position (20 degrees-30 degrees), and at 10-minute intervals thereafter. The results showed that ETCO2 was highly correlated with PaCO2 in group 1 (correlation coefficient r = 0.85), but not in group 2 (r = 0.55). In group 2, the PaCO2/ETCO2 gradient increased as time elapsed, with significant differences (p < 0.05) between the values at induction and those at 30 minutes after the change to the Trendelenburg position and thereafter. These results indicate that the ETCO2 and PaCO2 values correlate well during the first 20 minutes after the change to the Trendelenburg position in laparoscopy patients receiving TIVA with spontaneous breathing, but that PaCO2 monitoring is still necessary.

Abstract
Laparoscopy under total intravenous anesthesia (TIVA) with spontaneous respiration is a commonly encountered procedure in ambulatory gynecologic surgery. The purpose of this study was to evaluate the efficacy of TIVA using propofol and ketamine, compared with endotracheal inhalational general anesthesia (EIGA) for ambulatory gynecologic laparoscopy. Fifty-eight female patients, aged 17-48 years, were randomly allocated into two groups. Group 1 (TIVA) (n = 28) received propofol at the induction of anesthesia followed by propofol infusion for maintenance. Intravenous ketamine 0.5 mg/kg was administered before operation for anesthetic effect. Natural airway and spontaneous breathing were then maintained in patients. Group 2 (n = 30) received EIGA with isoflurane under controlled ventilation. We found that the two groups demonstrated similar trend characters of pH and PaCO2 during operation and in recovery room. The incidence of postoperative vomiting was higher in group 2 than in group 1 (30% vs. 7%; p < 0.05). The incidence of intraoperative arrhythmia was higher in group 2 than in group 1 (40% vs. 3%; p < 0.001). Furthermore, the incidence of sore throat was higher in group 2 than in group 1 (47% vs. 7%; p < 0.001). We conclude that TIVA with spontaneous respiration is suitable for ambulatory gynecologic laparoscopy.

Abstract
Total intravenous anesthesia has recently become available for ambulatory surgery. It has the advantages of decreased air contamination from volatile anesthetics and decreased exposure of operating room personnel to volatile anesthetics. The purpose of this study was to compare the anesthetic properties of propofol/ketamine (total intravenous) anesthesia and thiopentone/halothane (intravenous and gaseous) anesthesia for herniorrhaphy or hydrocelectomy in children. Sixty children aged 2 to 7 years scheduled for herniorrhaphy or hydrocelectomy were allocated to two groups. The propofol/ketamine group (group 1) received a loading dose of intravenous propofol 3 mg/kg followed by propofol infusion 200 micrograms/kg/minute; additional bolus doses of propofol 1 mg/kg were given as needed or the infusion dose was increased or decreased by 33 micrograms/kg/minute as needed. Ketamine 1 mg/kg was administered intravenously 2 to 3 minutes before herniorrhaphy or hydrocelectomy to reinforce the analgesic and anesthetic effects of propofol. The thiopentone/halothane group (group 2) received intravenous thiopentone 6 mg/kg followed by halothane with 40% oxygen using a mask. Group 2 patients maintained spontaneous breathing with intermittent assistance and group 1 patients maintained spontaneous natural airway breathing during anesthesia. The scores on the postoperative assessment scale were higher in group 2 patients, indicating poorer anesthesia recovery characteristics, but the differences were not significant. Pain on injection was more frequent in group 1 (12/32) than in group 2 (2/28). The incidence of vomiting in group 2 (6/28) was significantly higher than in group 1 (0/32). We conclude that propofol/ketamine allows patients to maintain spontaneous natural airway breathing during anesthesia, and its analgesic and anesthetic effects are comparable to those of thiopentone/halothane. Propofol/ketamine is appropriate for pediatric herniorrhaphy and hydrocelectomy. It can be recommended for pediatric ambulatory surgery.

Abstract
One hundred and twenty-seven children aged 3-6 years were allocated to four groups. All of them received venous cannulation on the dorsum of the hand. On induction, the group L1, L2 and L3 patients received propofol 3 mg/kg mixed with lignocaine 0.15 mg/kg, 0.3 mg/kg, 0.6 mg/kg, respectively. The group T patients received thiopentone 3 mg/kg, then propofol 1.5 mg/kg mixed with lignocaine 0.075 mg/kg. Pain on injection was categorized into two-assessment items (facial expression and limbs withdrawal). The facial expression category were subdivided into none, mild (knit of brows), moderate (grimace), and severe (crying). The withdrawal of limbs was categorized into none, mild (withdrawal of hand), moderate (withdrawal of fore-arm and arm), severe (withdrawal of arm and twisting of body). Patients were monitored using an electrocardiogram, pulse oximeter, autonomic noninvasive blood pressure measuring device and capnography. The patient characteristics did not differ significantly among the four groups. Pain on injection was significantly more frequent in the group L1 patients (81%) compared with the group T (27%) patients. Increasing lignocaine dose reduced the incidence of pain graded as "moderate" or "severe" though there was no significant difference. The incidences of excitatory effect on propofol injection were reduced with increasing lignocaine dose and prior administration of thiopentone but there were no obviously differences among groups. We concluded that thiopentone reduced injection pain on propofol and should be recommended.

Abstract
One hundred patients with intolerable cancer pain were treated with intrathecal bolus injections of morphine(IT morphine). The study began 2 days later after port-A cath implantation and continued during the 12 weeks follow-up period. During the investigation, the dosages, pain intensity, side effects, complications, activity and acceptibility were recorded. Initially, the morphine test does(0.2mg) resulted in pain relief for 8-26 hrs (mean 13.4 hrs). Then, changing the morphine dosages or frequency of injections were relied upon the effect of the opiate to provide 24 hrs pain relief. The mean morphine requirements were 0.32mg in 1st week, 0.44mg in 4th week, 1.25mg in 8th week and 1.43mg in 12th week. The mean morphine dose before IT treatment was 36.4mg. The vast majority of patients' pain intensity decreased prominently after IT morphine treatment. But pain was aggravated in the 12th week although the morphine dose increased. Side effects were minimal, and only one patient suffered from meningitis. Complications included 8 patients with port-A system dysfunction, one with anterior spinal artery syndrome, and one case of cauda equina syndrome. Activity improved significantly and all patients accepted the kind of treatment though some patients did not experience completely satisfactory relief from pain. Intrathecal morphine therapy uses only small amounts of opiate to achieve the optimal level of pain relief. So it offers a beneficial treatment option to patients whose pain has become intolerable or who have poor responsiveness to systemic narcotics.

Abstract
The sedating effect and influence of walkman music on 120 patients, that were randomly divided into a music and non-music group, who had received epidural anesthesia were investigated. It was found that significantly fewer patients in the music group felt anxious during surgery (P = 0.049). Meanwhile, heart rate and mean arterial pressure of the non-music group remained at a higher level, resulting in higher heart loading. Furthermore, patients listening to music had a significantly smaller need of sedatives (P = 0.001). With the purpose of reducing the consumption of sedatives, and offering a better anesthetic environment, we recommend the use of music during regional anesthesia.
