[Background]: Fluticasone propinate (FP), an inhaled steroid agent, has greater clinical efficacy in bronchial asthma than Beclomethasone dipropionate (BDP), but it has been reported that the rate of oropharyngeal candidiasis becomes high. In this study, we evaluated the medium-term pharyngeal candidiasis rate in elderly patients after BDP was replaced with FP in maintenance therapy.
[Method]: A total of 53 elderly patients 65 and over, who had previously received stable maintenance therapy with BDP, were switched to treatment with half doses of FP, and they were taught to gargle again.
Eight weeks and six months later, pharyngeal swabs were taken for culture and assessment of candidiasis. These results were compared with those of 24 patients 64 and below. We also measured the inspiratory peak flow rate with inhaled FP.
[Results]: Eight weeks later, candidiasis appeared in 11 patients in the advanced age group (20.8%), which was significantly high compared with only one patient in the age group under 65 (4.2%). Although the pharyngeal candidiasis of 8/11 patients became negative by teaching them thoroughly how to gargle with povidone-iodine, candidiasis appeared in another seven patients six months later, bringing the total up to 10/53 (18.9%).
[Conclusion]: The appearance rate of pharyngeal candidiasis in the elderly patients, who changed for FP, was unexpectedly high. It was suggested that the frequncy of gargling after inhaling FP and the inspiratory peak flow rate when FP is inhaled could be big influential factors. When we use FP, it may be important to give medium and long term-persistent instructions to patients.

Background. In recent years, aortic valve stenosis in the elderly is increasing. To determine the treatment of aortic stenosis in the elderly, we retrospectively evaluated the patients who underwent aortic valve replacement. Method. Between 1992 and 1997, 22 patients older than 70 years underwent aortic valve replacement for aortic stenosis. There were 15 women and 7 men, with a mean age of 73.0±4.0 years. Seven patients underwent concomitant procedures: 5 patients required coronary artery bypass grafts, 1 mitral valve plasty and 1 aortic root plasty. SJM prosthetic valves of sizes 19mm, 21mm and 23mm were used in 11, 8 and 3 patients respectively. Nobody underwent aortic annuloenlargement. Three patients underwent supraannular aortic valve replacement. All patients had New York Heart Association (NYHA) class III or IV symptoms. Results. There was no operative or hospital death. Five patients had atrial fibrillation after operation. There was only one late death, due to a traffic accident, and there was no significant complication during the follow up period. Of the 22, 21 patients improved to NYHA class I or II after operation. There were significant differences between patients who were 70 years or more and those under 70. BSA in these two groups were 1.495 and 1.615m²; p<0.01, and the amounts of blood transfusion were 918±702 and 408±428ml, p<0.01. However, there was no significant difference between these two groups in terms of ACC time (56.8 and 59.9min), CPB time (88.7 and 92.1min), ICU stay (4.0 and 3.3 days) and hospital stay (29.5 and 25.5 days). Conclusion. The results of aortic valve replacement in patients aged 70 years or more, were satisfactory. If the aortic annulus being small, a small mechanical valve prosthesis is suitable, and supraannular positioning yielded good results.

Background: Operative blood loss during open-heart surgery has been decreasing recently. We have stopped predonated autologous blood transfusions to reduce hospital stay and cost. Material and methods: In 70 consecutive elective open-heart cases, we used intraoperative hemodilutional autologous transfusions and intraoperative autotransfusions to avoid homologous blood transfusion. Predonated autologous blood transfusion was not used. All patients received an infusion of high-dose tranexamic acid prior to and after cardiopulmonary bypass (CPB). Results: Homologous blood transfusion was not required in 77.1% of patients who underwent open-heart surgery. When further classified, 84.5% of patients who underwent primary open-heart surgery, 41.7% of patients who underwent a reoperation, and 33.3% of patients who were preoperatively anemic did not require homologous blood transfusion. In patients who undergo reoperation and who are preoperatively anemic, the rate of homologous blood transfusion is high. Therefore, during the reoperation, intraoperative autologous blood transfusion should be used before starting CPB, and iron should be given to anemic patients prior to reoperation. Conclusion: Our strategy of blood conservation consists of intraoperative hemodilutional autologous transfusion, intraoperative autotransfusion, infusion of high-dose tranexamic acid prior to and after CPB and, avoiding predonated autologous blood transfusion. Based on our experience, predonated autologous blood transfusion is usually unnecessary for cases who undergo surgery for the first time and are not anemic. Predonated autologous blood transfusion should be reserved only for high risk patients with anemia and reoperation cases. For further blood conservation, we need to study the safety limits of non-transfusion in open-heart surgery.

OBJECTIVETo investigate the genes involved in pulmonary metastasis of human fibrosarcoma HT1080 cells in nude mice.

METHODSHT1080 cells were injected into the tail vein of BALB/ C nude mice. RNA samples were extracted from pulmonary metastatic tissues and normal control lung tissues, purified using Atlas Pure Total RNA labeling System (Clonetech Laboratories). cDNA probes labeled with 32P were prepared and hybridized to a cDNA membrane constructed with spots of 1176 human cancer related genes and radioactivities on the membrane were measeured by BAS 5000. The mRNA expression of gene FN1 was determined by real time RT-PCR using TaqMan methods. Furthermore, cells with FN1 expression were localized and obtained in situ in pulmonary metastatic foci by laser captured microdissection, and the FN1 expression was quantitated by real time RT-PCR.

RESULTSOf the total 1176 genes, 27 genes (2. 3%) revealed to be apparently up-regulated and 4 genes (0. 3% ) down-regulated. Real time RT-PCR analysis verified significant up-regulation of gene FN1. Laser captured microdissection/ real time RT-PCR analysis demonstrated up-regulated gene FN1 not in stroma cells but in tumor cell nests.

CONCLUSIONGene FN1 expression in fibrosarcoma HT1080 cells may be involved in pulmonary metastasis.

BACKGROUND: Several studies have shown that better placement of the acetabular cup and femoral stem can be achieved in total hip arthroplasty (THA) by using the computer navigation system rather than the free-hand alignment methods. However, there have been no comparisons of the relevant clinical advantages in using the computer navigation as opposed to the manual intraoperative measurement devices. The purpose of this study is to determine whether the use of computer navigation can improve postoperative leg length discrepancy (LLD) compared to the use of the measurement device. METHODS: We performed a retrospective study comparing 30 computer-assisted THAs with 40 THAs performed using a simple manual measurement device. RESULTS: The postoperative LLD was 3.0 mm (range, 0 to 8 mm) in the computer-assisted group and 2.9 mm (range, 0 to 10 mm) in the device group. Statistically significant difference was not seen between the two groups. CONCLUSIONS: The results showed good equalization of the leg lengths using both computed tomography-based navigation and the simple manual measurement device.

We present a rare case of a patient who underwent complete microendoscopic excision of an osteoid osteoma, which induced radiculopathy without nerve root compression. A 20-year-old man presented severe right groin pain that was temporarily relieved by nonsteroidal anti-inflammatory drugs. A computed tomography (CT) scan showed typical features of a nidus located in the inferior cortex of the right L3 pedicle. We performed surgery using a posterior microendoscopic approach. We drilled vertically along the line of the cortex of the caudal pedicle using a high-speed drill. After identifying the tumor, en bloc resection of the nidus was achieved. Immediately after surgery, pain in the right groin disappeared. A CT scan showed that most of the right L3 pedicle remained. This minimally invasive technique preserves spinal structures, including the facet and pedicle, and is a viable option for the treatment of spinal osteoid osteomas located close to vital structures.

STUDY DESIGN: Case-control study. PURPOSE: To evaluate the surgical magnitude and learning curve of "second-generation" total en bloc spondylectomy (TES). OVERVIEW OF LITERATURE: In June 2010, we developed second-generation TES combined with tumor-induced cryoimmunology, which does not require autograft harvesting. METHODS: TES was performed in 63 patients between June 2010 and September 2013. Three groups of patients were evaluated: 20 undergoing surgery in the first year of development of second-generation TES (group I), 20 in the second year (group II), and 23 in the third year (group III). Patient backgrounds showed no remarkable differences. Operating time, intraoperative blood loss, blood transfusion, and postoperative C-reactive protein and creatine phosphokinase were compared among the groups. RESULTS: Mean±standard deviation operating time was 486±130 minutes in group I, 441±85 minutes in group II, and 396±75 minutes in group III. The time was significantly shorter in group III than in group I (p<0.05). Intraoperative blood loss was 901±646 mL in group I, 433±177 mL in group II, and 411±167 mL in group III. Blood loss was significantly lower in groups II and III than in group I (p<0.01). Transfusion was not required in 20 of 23 patients in group III, and mean C-reactive protein levels on postoperative day 3 were significantly lower in this group than in group I (6.12 mg/L vs. 10.07 mg/L; p<0.05). Postoperative creatine phosphokinase levels did not differ among the groups. CONCLUSIONS: TES is associated with a significant learning curve. Thus, second-generation TES can no longer be considered highly invasive.

STUDY DESIGN: A retrospective study. PURPOSE: To evaluate the immunity-enhancing effect of implantation of a liquid nitrogen-treated tumor. OVERVIEW OF LITERATURE: We have developed a new technique of implanting a tumor frozen in liquid nitrogen after posterior decompression and stabilization, with the aim of enhancing antitumor immunity in order to prolong the survival period of the patient. In the current study, the immunity-enhancing effect of this new technique has been evaluated. METHODS: The subjects were 19 patients in whom we had earlier performed decompression and stabilization between April 2011 and September 2013. The 19 subjects were divided into two groups, namely a frozen autologous tumor tissue implantation group (n=15; "implantation group"), which consisted of patients, who underwent implantation with autologous tumor tissue frozen in liquid nitrogen, and a control group (n=4), which consisted of patients, who did not undergo autologous cancer transplantation. To evaluate the immunity-enhancing effect of the protocol, plasma cytokines (interferon [IFN]-gamma and interleukin [IL]-12) were analyzed before surgery and a month after surgery. RESULTS: The mean rate of increase in IFN-gamma was significantly higher in the implantation group (p=0.03). Regarding IL-12, no significant difference was observed between the groups, although the implantation group exhibited increased levels of IL-12 (p=0.22). CONCLUSIONS: Decompression and stabilization combined with autologous frozen tumor cell implantation can enhance cancer immunity in metastatic spinal tumor patients. It is hypothesized that this procedure might prevent local recurrence and prolong survival period.

OBJECTIVE: To analyze patient characteristics of cancer rehabilitation and outcomes at our hospital. METHODS: This retrospective study analyzed 580 patients, who underwent cancer rehabilitation at our hospital and rehabilitation outcome after therapy were investigated. The relationship between the initial Barthel index and discharge outcomes was investigated, with a special focus on cancer patients with bone metastasis. The Barthel index and performance status (Eastern Cooperative Oncology Group) before and after rehabilitation were analyzed, and threshold value of home discharge was calculated from a receiver operating characteristic curve (ROC). General criteria for home discharge from our hospital included independence in performing basic activities of daily living such as bathing, feeding, and toileting or availability of home support from a family member/caregiver. RESULTS: The outcomes after rehabilitation among all the patients were as follows: discharge home 59%, death 13%, and others 27%. Statistical differences were observed between the initial and final values of the Barthel index in patients with bone metastasis, who could be discharged home (p=0.012). ROC analysis of the initial Barthel index for predicting home discharge revealed a threshold value of 60, sensitivity of 0.76, and specificity of 0.72. CONCLUSION: The patients with bone metastasis had a lower rate of home discharge and a higher rate of mortality than all the study patients who underwent cancer rehabilitation at our hospital. It is proposed that at the time of initiation of rehabilitation for patients with bone metastasis, an initial Barthel index lower than 60 might predict a worse outcome than home discharge.
