In recent years, high doses of morphine have come to be used to relieve pain in terminal cancer patients, but not all the patients are treated by this pain intervention method because of a poor understanding of terminal care. The authors have organized a terminal care confernce in order to solve this problem in our hospital.
The conference has been held 8 times over the past 18 months.
Cases of good pain control by high doses of morphine were demonstrated, and cancer pain control manuals were prepared for distribution to the medical staff.
After such activity, the total dosage of morphine in the hospital a year showed a sixfold increas.

Primary end-to-side anastomoses between the left upper pulmonary vein and left atrium performed in 21 puppies with continuous 5-0 polydioxanone (PDS) or polypropylene (PRO). Animals were sacrificed at 1, 7 and 28 days after operation. Stenosis occurred in one of 5 animals of the PDS group at 7 days and 28 days respectively, and one of 5 animals of the PRO group at 28 days. There was no significant difference between the two groups in terms of anastomosis patency. Histological examination showed slight tissue reaction and fibrosis surrounding the sutures in both groups. This study suggests that the absorbable monofilament suture material, in particular PDS, is useful for the repair of low pressure circulatory system and will not cause the stenosis of the anastomotic site.

STUDY DESIGN: Historical controlled trial. PURPOSE: To clarify the usefulness of cryotherapy after spine surgery. OVERVIEW OF LITERATURE: Cryotherapy has generally been performed subsequent to surgery on joints and in this application its clinical effects are well understood. However, cryotherapy has yet to be used following spine surgery. Its clinical efficacy in this context is unknown. METHODS: Thirty six patients had undergone one level microendoscopic surgery. Sixteen were enrolled into the cooling group, with the remaining 20 making up the no postoperative cryotherapy control group. Cryotherapy was performed at 5degrees C using an icing system. A silicone balloon catheter with a thermo sensor on the tip was placed in the surgical wound. The temperature in the wound was recorded every 30 minutes until the next morning. The relationship between the depth of the sensor and the temperature in the wound were investigated using simple linear regression analysis. Laboratory data, visual analogue scale (VAS) for wound pain and postoperative bleeding were investigated. RESULTS: The mean temperature in the surgical wound was 37.0 in the control group and 35.0degrees C in the cooling group (p<0.001). There was a positive correlation between the depth of the thermo sensor and the temperature in the wound in the cooling group (y=0.91x+30.2, r=0.67, p=0.004). There were no significant differences between the groups in terms of laboratory data, VAS or postoperative bleeding. CONCLUSIONS: The temperature in the wound was decreased significantly by spinal surgery cryotherapy.

Since the Infection Control Team (ICT) was organized in 1999, our hospital has been engaged in evidence-based operations against nosocomial infections. The ICT's major activities included guidance in preventive measures against infections, surveillance involving continuous environmental monitoring, proposition as regards prescription of antibacterial medicines, and consultation with clinicians about prophylaxis. The team comprising physicians, nurses, pharmacists and clinical laboratory technicians has made expert propositions to clinicians. To be concrete, the team members, with the liaison clerk playing a central role, met with physicians in charge or with other staff members of the hospital, studied the infection cases in question, and presented the study findings to the clinicians. Fundamentally, therefore, it is not that the ICT intervenes in the affairs of the clinical department by way of directions but that it presents clinicians with the ideas gained through discussion between ICT members and physicians and other hospital staffers. While cementing a relationship of mutual trust between hospital employees, the ICT is expected to engage in nosocomial infection prevention activities by joining forces transdeoartmentally.

STUDY DESIGN: Retrospective study. PURPOSE: To investigate the relationship between preoperative total spinal sagittal alignment and the early onset of adjacent segment degeneration (ASD) after single-level posterior lumbar interbody fusion (PLIF) in patients with normal sagittal spinal alignment. OVERVIEW OF LITERATURE: Postoperative early-onset ASD is one of the complications after L4–L5 PLIF, a common surgical procedure for lumbar degenerative disease in patents without severe sagittal imbalance. A better understanding of the preoperative characteristics of total spinal sagittal alignment associated with early-onset ASD could help prevent the condition. METHODS: The study included 70 consecutive patients diagnosed with lumbar degenerative disease who underwent single-level L4–L5 PLIF between 2011 and 2015. They were divided into two groups based on the radiographic progression of L3–L4 degeneration after 1-year follow-up: the ASD and the non-ASD (NASD) group. The following radiographic parameters were preoperatively and postoperatively measured: sagittal vertebral axis (SVA), thoracic kyphosis (TK), lumbar lordosis, pelvic tilt, and pelvic incidence (PI). RESULTS: Eight of the 70 patients (11%) experienced ASD after PLIF (three males and five females; age, 64.4±7.7 years). The NASD group comprised 20 males and 42 females (age, 67.7±9.3 years). Six patients of the ASD group showed decreased L3–L4 disc height, one had L3–L4 local kyphosis, and one showed both changes. Preoperative SVA, PI, and TK were significantly smaller in the ASD group than in the NASD group (p <0.05). CONCLUSIONS: A preoperative small SVA and TK with small PI were the characteristic alignments for the risk of early-onset ASD in patients without preoperative severe sagittal spinal imbalance undergoing L4–L5 single-level PLIF.

Pericardial pacing wire placement may occasionally result in intravascular or intratracheal wire migration, infective endocarditis, and sepsis; reportedly, the incidence of complications is approximately 0.09 to 0.4%. We report a case of a retained epicardial pacing wire that migrated into the pulmonary artery. A 66-year-old man underwent coronary artery bypass grafting for angina pectoris, with placement of an epicardial pacing wire on the right ventricular epicardium, 6 years prior to presentation. Some resistance was encountered during wire extraction; therefore, it was cut off at the cutaneous level on postoperative day 8. Computed tomography performed 6 years postoperatively revealed migration of the pacing wire into the pulmonary artery, and it was removed using catheter intervention. Surgeons should be aware of complications associated with retained pacing wires in patients in whom epicardial wires are retained after cardiac surgery.

When performing aortic valve replacement in young patients, mechanical valves are recommended due to their durability. However, because mechanical valves require lifelong use of warfarin and carry risks such as easy bleeding, bioprosthetic valve replacement may be performed in some cases even in young patients. In this report, we describe a case of a patient who underwent bioprosthetic aortic valve replacement with aortic annular enlargement in anticipation of TAV in SAV and had a good postoperative course. The patient is a 51-year-old male. He was referred to our hospital for surgical treatment of severe aortic stenosis. The patient strongly preferred a bioprosthetic valve due to the disadvantage of taking warfarin. Therefore, we considered the possibility of TAV in SAV due to his young age, and decided to perform aortic annular enlargement if necessary. Intraoperatively, after resection and decalcification of the valve, a sizer was inserted, but the 19 mm sizer could not pass through, so we decided to perform aortic annular enlargement. Aortic annular enlargement was performed by suturing a Dacron patch and implantation of a 23 mm bioprosthetic valve. The patient had no major postoperative problems and was discharged home on the 14th day after surgery. In order to avoid PPM in the future when TAVI is performed, aortic annular enlargement should be considered in young patients undergoing aortic valve replacement using a bioprosthetic valve if TAV in SAV is considered to be difficult.
