STUDY DESIGN: Retrospective case series. PURPOSE: To investigate the oncological outcomes, including distant relapse, after en bloc spondylectomy (EBS) for spinal metastases in patients with a minimum of 2-year follow-up. OVERVIEW OF LITERATURE: Although EBS has been reported to be locally curative and extend survival in select patients with spinal metastases, detailed reports regarding the control of distant relapse after EBS are lacking. METHODS: We conducted a retrospective review of 18 consecutive patients (median age at EBS, 62 years; range, 40–77 years) who underwent EBS for spinal metastases between 1991 and 2015. The primary cancer sites included the kidney (n=7), thyroid (n=4), liver (n=3), and other locations (n=4). Survival rates were estimated using the Kaplan–Meier method, and groups were compared using the log-rank method. RESULTS: The median operative time and intraoperative blood loss were 767.5 minutes and 2,375 g, respectively. Twelve patients (66.7%) experienced perioperative complications. Five patients (27.8%) experienced local recurrence of the tumor at a median of 12.5 months after EBS, four of which had a positive resection margin status. Thirteen patients (72.2%) experienced distant relapse at a median of 21 months after EBS. The estimated median survival period after distant relapse was 20 months (95% confidence interval, 0.71–39.29 months). No association was found between resection margin status and distant relapse. Overall, the 2-year, 5-year, and 10-year survival rates after EBS were 72.2%, 48.8%, and 27.1%, respectively. Importantly, the era in which EBS was performed did not impact the oncological outcomes. CONCLUSIONS: Our results suggest that EBS by itself, even if margin-free, cannot prevent further dissemination, which occurred in >70% of patients at a median of 21 months after EBS. These results should be considered and conveyed to patients for clinical decision-making.

STUDY DESIGN: Observational cohort study. PURPOSE: To assess the surgical outcomes of posterior decompression and fusion for cervical myelopathy in patients with athetoid cerebral palsy. OVERVIEW OF LITERATURE: Patients with athetoid cerebral palsy demonstrate involuntary movements and develop severe cervical spondylosis with kyphosis. In these patients, surgery is often performed at an early age because of myelopathy. A few studies have reported about the long-term outcomes of surgical treatment; however, they contain insufficient information. METHODS: From 2003 to 2008, 13 patients with cervical myelopathy due to athetoid cerebral palsy underwent posterior fusion surgery and were included in this study. The Japanese Orthopaedic Association (JOA) score, neck disability index (NDI), C2–7 angle on radiography, and need for additional surgical treatment were examined at 1 and 5 years postoperatively. RESULTS: The mean C2–7 angle was −10.5°±21.1° preoperatively and was corrected to −2.9°±13.5° immediately postoperatively. This improvement was maintained for 5 years. The JOA score was 9.5±2.5 preoperatively and 12.2±1.7 at the 5-year follow-up. NDI was 17±6.9 preoperatively and 16±7.5 at the 5-year follow-up. Patient satisfaction with surgery on a 100-point scale was 62.2±22.5 at the 5-year follow-up. Three patients needed additional surgery for loosening of screws. These results demonstrate good surgical outcomes for posterior fusion at 5 years. CONCLUSIONS: Posterior decompression and fusion should be considered a viable option for cervical myelopathy in patients with athetoid cerebral palsy.

BACKGROUND: Cleft lip and palate repair requires a deep and small surgical field and is usually performed by surgeons wearing surgical loupes. Surgeons with loupes can obtain a wider surgical view, although headlights are required for the deepest procedures. Surgical microscopes offer comfort and a clear and magnification-adjustable surgical site that can be shared with the whole team, including observers, and easily recorded to further the education of junior surgeons. Magnification adjustments are convenient for precise procedures such as muscle dissection of the soft palate. METHODS: We performed a comparative investigation of 18 cleft operations that utilized either surgical loupes or microscopy. Paper-based questionnaires were completed by staff nurses to evaluate what went well and what could be improved in each procedure. The operating time, complication rate, and scores of the questionnaire responses were statistically analyzed. RESULTS: The operating time when microscopy was used was not significantly longer than when surgical loupes were utilized. The surgical field was clearly shared with surgical assistants, nurses, anesthesiologists, and students via microscope-linked monitors. Passing surgical equipment was easier when sharing the surgical view, and preoperative microscope preparation did not interfere with the duties of the staff nurses. CONCLUSIONS: Surgical microscopy was demonstrated to be useful during cleft operations.

BACKGROUND: Listeria monocytogenes (L. monocytogenes) is a rare causative pathogen of brain abscess that is often found in immunocompromised patients. Although patients with supratentorial listerial abscesses showed a longer survival with surgical drainage, the standard therapy for patients with subtentorial lesions has not been established. CASE REPORT: We report herein a patient with supra- and subtentorial brain abscesses caused by L. monocytogenes infection. These abscesses did not respond to antibiotics, and his symptoms gradually worsened. Drainage was not indicated for subtentorial lesions, and the patient was additionally treated with hyperbaric oxygen therapy, which dramatically reduced the volume of abscesses and improved the symptoms. CONCLUSIONS: This is the first report of drastic therapy for a patient with listerial brain abscesses involving combined antibiotics and hyperbaric oxygen therapy. The findings suggest that hyperbaric oxygen therapy is a good option for treating patients with deep-seated listerial abscesses and for who surgical drainage is not indicated.

OBJECTIVE: The aim of this study was to explore the factor structure of a novel, 10-item rating scale, the Targeted Inventory on Problems in Schizophrenia (TIP-Sz). Determining the factor structure will be useful in the brief evaluation of medication and non-medication treatment of the disease. METHODS: An exploratory factor analysis was performed on TIP-Sz scores obtained from 100 patients who met the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria for schizophrenia. RESULTS: The factor analysis extracted four factors that were deemed clinically pertinent, which we labeled: disorganization, social cooperativeness, functional capacity, and emotional state. The items exhibited cross-loadings on the first three factors (i.e., some items loaded on more than one factor). In particular, the 'behavioral dyscontrol and disorganization,' 'insight and reality testing,' and 'overall prognostic impression' items had comparable cross-loadings on all of the first three factors. The emotional state factor was distinct from the other factors in that the items loading on it did not cross-load on other factors. CONCLUSION: The TIP-Sz scale comprises factors that are associated with the psychosocial functioning and emotional state of patients, which are important outcome parameters for successful treatment of the disease.

[Objective]To clarify that acupuncture of Cu and Zn at dynamic acupoints had significantly decreased oxidation-reduction potential (ORP) in the local epidermis. In this study, we evaluated the influences of moxibustion on the ORP and hydrogen ion concentration (pH) in the local epidermis.
[Methods]In volunteers and patient groups, direct moxibustion, moxa-needle and BANSHIN were performed.
[Results]In all stimulation methods, the ORP showed no changes at non-acupoints, but it significantly decreased at dynamic acupoints. A significant decrease in pH was observed after direct moxibustion at both non-acupoints and dynamic acupoints. On the contrary, pH showed a significant increase after moxa-needle, and radiant heat of which had been cut off.
[Conclusion]Direct moxibustion at plus points and moxa-needle at minus points clarified a part of the mechanisms of the effects of direct moxibustion and moxa-needle.

Transcatheter embolization of 25 aortopulmonary collateral arteries (7 bronchial arteries and 18 intercostal arteries) was attempted prior to intracardiac repair in 7 patients. The underlying disease was tetralogy of Fallot in 3 patients, pulmonary atresia with ventricular septal defect in 2, double-outlet right ventricle with ventricular septal defect and pulmonary stenosis in 1 and tricuspid stenosis with pulmonary atresia in 1. The intervals between embolization and intracardiac repair ranged from 0 to 17 days (mean 4.5 days). Embolization resulted in total occlusion in 7 bronchial arteries and 17 intercostal arteries, with an overall success rate of 96%. Complications included a coil dislodgement from a collateral artery into the aorta in one patient, necessitating surgical removal of the dislodged coil from the femoral artery, an exacerbation of cyanosis and dyspnea on exercise in 5, and slight fever in 2. In one patient with tetralogy of Fallot, who had 5 collateral vessels, transcatheter embolization caused hypoxemia, bradycardia and hypotension and therefore intracardiac repair was performed immediately after embolization. Aortopulmonary collateral arteries in patients with congenital heart disease can be effectively treated by transcatheter embolization. Embolization should be performed just before intracardiac repair because an excessive decrease in arterial oxygen saturation after embolization may require an emergency operation.

Thirty-four patients with congenital cardiac disease were studied to evaluated the role of ultrafiltration after cardiopulmonary bypass without homologous blood transfusion. We used either polypropylene microporous hollow fiber hemoconcentrator (HC-30M or 100M) or polyacrylonitrile microporous hollow fiber hemoconcentrator (PHC-500). Ultrafiltration was useful in the reduction of fluid overloading after cardiopulmonary bypass with extreme hemodilution. Thirty-two patients tolerated the procedure uneventfully without donor blood transfusion and were discharged from the hospital. The values of hematocrit, serum protein and free hemoglobin increased significantly after ultrafiltration with either type of hemoconcentrator. However the degree of concentration of blood components was significantly higher with polyacrylonitrile hemoconcentrator than those with polypropylene hemoconcentrator. These results indicated that ultrafiltration was useful for maintaining water balance after cardiopulmonary bypass without homologous blood transfusion in pediatric cardiac surgery and that polyacrylonitrile microporous hollow fiber hemoconcentrator should be employed in patients with shorter bypass time and less hemolysis.
