To assess the extent of functional gains measured before and after inpatient rehabilitation in patients who have brain tumors, and to identify whether the tumor type, tumor laterality, side of hemiparesis, postoperative addition therapy, cognitive dysfunction, and impairment of consciousness influences outcome. We reviewed the Barthel index(BI)of patients admitted to our hospital from Feb. 2004 to Jan. 2006. Participants numbered 133 persons, aged 52.2±15.4 years old and comprised 57 males and 76 females. All participants had functional impairments resulting from their brain tumors, and patient data was collected from their medical records retrospectively. The numbers of the patients by tumor pathology were 68 gliomas(16 Grade I·II, 52 Grade III·IV), 19 meningiomas, 15 metastatic brain tumors and 31 others. Significant improvements were found between admission and discharge BI scores for all patients, including the glioma group, meningioma group and metastatic tumor group. A significant change of BI improvement was noted between the glioma group and the meningioma group. Length of rehabilitation stay for the glioma group was significantly longer than for the meningioma and metastatic tumor groups. The highest percentage of patients discharged to home was in the glioma group(77.9%). Tumor laterality, side of hemiparesis and postoperative addition therapy all affected functional improvement. We concluded that acute inpatient rehabilitation is an effective treatment for patients with brain tumors that can help them to regain functional ability and to improve their quality of life.

To identify the most frequently reported preferred terms (PTs) in the cases of rheumatoid arthritis (RA) patients treated with immunosuppressive biological drugs as suspected drugs, we analyzed the cases in the Japanese Adverse Drug Event Report (JADER) database. We found that pneumonia, interstitial lung disease, Pneumocystis jiroveci pneumonia (PCP), cellulitis, sepsis, and herpes zoster were the most frequently reported PTs. We obtained the reporting odds ratio (ROR) and the time to onset of these six PTs and compared them in the cases reported for each immunosuppressant as a suspected drug. We focused on RA treatment, including five tumor necrosis factor (TNF) antagonists (infliximab, etanercept, adalimumab, golimumab, and certolizumab pegol). For pneumonia, interstitial lung disease and sepsis, no specific correlation was observed for each immunosuppressant for RA. In the case of PCP, the highest ROR was observed in the patients treated with infliximab. The time to onset of PCP in the infliximab-treated patients (median, 0.19 yr) was significantly shorter than the onset time in the patients treated with tocilizumab, an interleukin-6 receptor blocker that is another type of drug for RA(0.32 yr, p<0.01, Mann-Whitney test). The onset time in the patients treated with golimumab (0.24 yr) was also significantly shorter than the onset time for tocilizumab(p<0.05), but the ROR was not as high. These results suggested a correlation between PCP and infliximab. In the cases of cellulitis and herpes zoster, a similar correlation was observed with tocilizumab and certolizumab pegol, respectively. We should consider these results when patients have a respiratory disorder or skin/subcutaneous tissue disorder.

Background : The aim of this study was to assess the effects of repeated injections of botulinum toxin type A (BoNT-A) combined with a rehabilitative program for treating spastic upper limb hemiparesis after stroke. Subjects and methods: Subjects were 112 poststroke hemiparetic patients with spastic upper limb (mean age : 55.5±11.6 years ±SD, mean period between onset and first injection : 5.1±3.5 years). For each patient, BoNT-A (maximum dose of each injection : 240 units) was injected in the spastic muscles of the affected upper limb twice with a minimum interval of 3 months. Following each injection, detailed one-to-one instructions for homebased functional training was provided. At the baseline (before injection) and at 1 and 3 month follow-ups after each injection, the patient's modified Ashworth scale (MAS), the range of motion (ROM) and Fugl-Meyer Assessment (FMA) were evaluated. Results : The total score for the upper limb and the scores of categories A and B of the FMA increased significantly not only after the first injection but after the second injection compared with the second baseline, while the FMA score for category D increased significantly only after the second injection. MAS also decreased significantly not only after the first injection but after the second injection compared to the second baseline. Conclusion : A more significant improvement was found not only in muscle spasticity but also in upper limb motor function after two BoNT-A injections. It is suggested that repeated BoNT-A injections followed by a comprehensive rehabilitative program would be an effective treatment for limb spasticity after a stroke.

We performed a 15 day protocol of low-frequency repetitive transcranial magnetic stimulation (rTMS) combined with intensive occupational therapy in hemiplegic upper limbs in poststroke and investigated the effect of cerebral blood flow using single photon emission computed tomography (SPECT). Seventeen chronic stroke patients were studied with SPECT at rest before and 4 weeks after undergoing the 15 day protocol. Before and after the treatment, Fugl-Meyer Assessment (FMA) score and Wolf Motor Function Test (WMFT) -Log performance time showed a significant improvement. The specific areas with a significant increase in perfusion in the affected hemisphere were the insula (BA 13), the precentral gyrus (BA 44) and the cerebellum. In the nonaffected hemisphere, perfusion was significantly increased in the lingual gyrus and cerebellum. On the other hand, perfusion was significantly decreased in the middle frontal gyrus (BA 6), precentral gyrus (BA 4) and postcentral gyrus (BA 3) in the nonaffected hemisphere. It was suggested that low-frequency rTMS combined with intensive occupational therapy effects the cerebral blood flow and contributes to improving upper limb hemiplegia after stroke.

This study aimed to estimate the cost-effectiveness of pregabalin treatment for neuropathic pain.
Design:Long-term simulations based on state transition models.
Methods:We examined the cost-effectiveness of pregabalin for treatment of three common peripheral neuropathic pains, postherpetic neuralgia(PHN), painful diabetic peripheral neuropathy(DPN), and radiculopathy, using the incremental cost-effectiveness ratio(ICER). We used quality-adjusted life years(QALYs)as an index of effectiveness, and also estimated medical costs. For PHN and DPN, we constructed state transition models comprising two states, with and without pregabalin treatment, and performed 52-week simulations. The pain scores reported in Japanese phaseIII studies were used to set patients' weekly pain scores. The results of utility surveys conducted overseas were used as utility scores, while values randomly sampled from probability distributions were used to set weekly pain scores and drop-out rates. In base-case analyses, we performed 1000 1st-order Monte Carlo simulations using 1000 values randomly sampled from probability distributions, and calculated QALYs and medical costs for 52 weeks for each group. For radiculopathy, the ICER was calculated from changes in QALYs for 12 weeks reported overseas and medical costs estimated separately for the identical period.
Results:The ICERs for PHN, DPN, and radiculopathy were 1,116,886 Yen/QALY, 1,100,420 Yen/QALY, and 1,095,943 Yen/QALY, respectively, which were well below the upper limits of ICER ranges for treatments considered cost-effective. There were no cases in which ICERs obtained from scenario and sensitivity analyses differed significantly.
Conclusion:Pregabalin was shown to be cost-effective treatment for neuropathic pain.
