We experienced a case of chronic pain responding to electrical acupuncture therapy while on spinal cord stimulation. A 35 year-old male presented with chronic neck pain. At 16 years of age, he had neck pain due to traffic accident with stellate ganglion block and epidural block. At 29 years of age, he sensed radiating pain in the 3rd to 5th digits of the left hand during epidural block. At 33 years of age, nerve root injury occurred after insertion of an epidural catheter, resulting in epidural abscess. Although the abscess resolved after antibiotic treatment, he had stiff fingers in the left hand together with neck pain and restricted range of motion of the neck. At 34 years of age, a spinal cord stimulation device was inserted which improved the stiff fingers in the left hand, but not the neck pain and restricted neck motion. He therefore visited our institute. At presentation, neck pain together with dysphagia and mastication pain were observed, and the patient was on a liquid diet. He was given electrical acupuncture treatment in additional to trigger point block and stellate ganglion laser. After two treatments, he was able to resume a normal diet. With reduced neck pain, he also undergo rehabilitation mainly through voluntary neck movements. This case demonstrates that electrical acupuncture treatment may be safe and effective for patients fitted with spinal cord stimulation device.

Development of direct oral anticoagulants and their antidotes has led to the need to reconsider the eligibility of acute stroke patients who have been taking oral anticoagulants for intravenous thrombolysis. Officially authorized Japanese guidelines on this issue were revised twice at the time of approval for clinical use of direct oral anticoagulants and idarucizumab, a specific reversal agent for dabigatran. A unique recommendation in the latest Japanese clinical guides was that thrombolysis can be recommended if the time of the last dose of direct oral anticoagulants exceeds 4 hours and if commonly available anticoagulation markers are normal or subnormal, i.e., international normalized ratio of prothrombin time < 1.7 and activated partial thromboplastin time < 1.5 times the baseline value (≤40 seconds only as a guide). These criteria are partly supported by the findings of domestic multicenter and single-center surveys that symptomatic or asymptomatic intracranial hemorrhage following thrombolysis was rare under the conditions of the criteria. Even for dabigatran users, stroke thrombolysis can be considered without pretreatment by idarucizumab if patients meet the above criteria. If not, direct mechanical thrombectomy can be considered without pretreatment by idarucizumab or thrombolysis, and use of idarucizumab, followed immediately by thrombolysis, can be considered only when thrombectomy cannot be quickly performed. These clinical guides are practical and to some extent economical, but they have some limitations, including lack of corroborating information from sufficient numbers of relevant cases. The guides will be further modified based on the results of future research.

A 68-year-old man with a right common iliac artery aneurysm perforating the inferior vena cava showed cardiomegaly and pulmonary congestion with left leg edema and dyspnea on exertion. The patient demonstrated a hyperdynamic circulation characterized by increased filling pressure, low systemic resistance, and high cardiac output (9.81l/min/m2) before surgery with a pulmonary-to-systemic blood flow ratio of 1.36. At operation, the right iliac artery to the inferior vena cava fistula, 5×10mm across, was closed along with resection and replacement of the aneurysm with a woven dacron graft of 10mm in diameter. The procedure caused acute and dramatic changes both in pre- and after-loads associated with aortic clamping as well as with elimination of A-V shunt through the fistula. Diligent attention was required both by surgeons and anesthesiologists to cope with these rather dramatic hemodynamic shifts during and after surgery. The patient did well and was discharged with normal hemodynamic parameters.

A 76-year-old woman with Stanford type A acute aortic dissection underwent replacement of the ascending aorta with the use of gelatin-resorcin-formalin glue. The patient suffered sudden cardiogenic shock at home 15 months after surgery and was admitted to the Emergency Center of our hospital. A series of examinations revealed an aortic-root pseudoaneurysm associated with anastomotic disruption. Cardiogenic shock caused by obstruction of the ascending aortic graft due to anastomotic disruption was diagnosed. An intraaortic balloon pump (IABP) was inserted, and the patient's circulatory status improved. On the following day, reanastomosis of the aortic root graft was performed. On day 32 after surgery, the patient was discharged from the hospital in good condition. IABP can stabilize circulatory status and improve cardiogenic shock in the short term in patients with an aortic-root pseudoaneurysm caused by narrowing of the graft lumen, as in the present patient. IABP may thus be a useful ancillary measure before radical operation.

OBJECTIVE: The anti-epileptogenic drug levetiracetam has anticonvulsant and anti-epileptogenesis effects. Synergy between cell death and inflammation can lead to increased levels of apoptosis inhibitory factors and brain-derived neurotrophic factor, aberrant neurogenesis and extended axon sprouting. Once hyperexcitation of the neural network occurs, spontaneous seizures or epileptogenesis develops. This study investigated whether the anti-epileptogenic effect of levetiracetam is due to its alternate apoptotic activity. METHODS: Adult male Noda epileptic rats were treated with levetiracetam or vehicle control for two weeks. mRNA quantification of Bax, Bcl-2 and GAPDH expression were performed from prefrontal cortex and hippocampus tissue samples. RESULTS: The levetiracetam-treated group showed a significant increase of Bax/Bcl-2 mRNA expression ratio in the prefrontal cortex than the control group, but no change in the Bax/Bcl-2 mRNA expression ratio in hippocampus. CONCLUSION: Idiopathic generalized epilepsy including childhood absence epilepsy develop at childhood and recover spontaneously during adolescence. The aberrant neural excitable network is pruned by a neural-maturing action. This study suggests the mechanism of acquired anti-epileptogenesis by levetiracetam treatment may be similar to spontaneous recovery of idiopathic generalized epilepsy during adolescence.

BACKGROUND AND PURPOSE: Plasma D-dimer levels are elevated during the acute phase of cerebral infarction (CI). We investigated whether the D-dimer level on admission and other clinical characteristics could be used to predict the poor outcome of patients with acute CI. METHODS: The clinical characteristics and plasma D-dimer levels measured within 3 days of onset were compared according to outcome among patients with acute CI. RESULTS: In total, 359 consecutive patients (mean age, 71.8 years) were examined, of which 174 had a poor outcome [score on the modified Rankin scale (mRS) > or =3] at 30 days after hospitalization. The mean mRS score was higher and a poor outcome was observed more frequently among women than among men (p<0.001 for each). The proportions of women, cardioembolism, atrial fibrillation, advanced age (> or =75 years), prior history of CI or transient ischemic attack, and elevated D-dimer level (> or =1.0 microg/mL) were significantly higher among patients with a poor outcome than among those with a good outcome. A multivariate analysis showed that elevated D-dimer level [> or =1.0 microg/mL; odds ratio (OR), 2.45; 95% confidence interval (95% CI), 1.52-3.89; p<0.01], advanced age (OR, 1.93; 95% CI, 1.21-3.07; p<0.01), and female gender (OR, 1.75; 95% CI, 1.08-2.83; p=0.02) were independent predictors of a poor outcome. CONCLUSIONS: Certain clinical characteristics (gender and advanced age) and an elevated D-dimer level upon admission can be used to predict the outcome of patients with acute CI at 30 days after hospitalization.

The Standardized Structured Medical record Information eXchange (SS-MIX) was started in 2006 as the project supported by the Ministry of Health, Labour and Welfare (MHLW) for promoting the exchange of the standardized medical information. Free soft wares developed in the project allow the storage of medical information to receive HL7 messages for prescription, laboratory test results, diagnoses and patient demographics in the hospital information system (HIS). We encourage the use of the SS-MIX standardized storage for postmarketing surveys and clinical studies. The recommendations consist of the following 7 parts. [1] In surveys and clinical studies, the information of drugs and laboratory test results in the SS-MIX standardized storage can be directly transferred to the electronic questionnaire and the investigators may obtain the information with high accuracy and granularity. [2] The SS-MIX standardized storage works as the backup system for the HIS because it can provide the minimum information essential in patient care even under the disastrous condition like earthquake or unexpected network failure. [3] The SS-MIX standardized storage may be useful to conduct a good pharmacoepidemiology study not only because it provides the information in the storage efficiently but also it can be used to identify “new users” who started the drug after some period of non-use.The “new user” design is often essential to have the unbiased results. [4] When the drug company conducts postmarketing surveys according to the current regulation, the use of the SS-MIX standardized storage will facilitate the fast and efficient collection of data to develop the timely measure to minimize the drug-related risk. With the SS-MIX standardized storage, it is also expected that many types of study design can be employed and the quality of data is improved in the survey. [5] The SS-MIX standardized storage maybe also useful to evaluate the risk minimization action plan by comparing the prescription pattern or incidence of the targeted adverse event between two periods before and after the implementation of the action plan. [6] In planning clinical trials, the SS-MIX standardized storage may be used to estimate the size of eligible patients. The storage may also allow conducting cross-sectional studies to know characteristics of diseases or drug treatment. In addition, cohorts of those who had coronary artery angiography, new users of a drug and those with a rare disease may be readily identified. Using such cohorts, investigators can initiate a case-control study nested within the cohort, pharmacogenomic studies and comparative effectiveness researches. [7] The SS-MIX standardized storage may be used as the formal data source in clinical trials in the future when some conditions are satisfied. For instance, the formal agreement should be reached between industry, government and academia on the use of standards of data structure in Clinical Data Interchange Standards Consortium (CDISC) and on the operation of computerized system validation (CSV) in the clinical trials.

Background:
and Purpose Differences in measurement of the extent of acute ischemic stroke using the Alberta Stroke Program Early Computed Tomographic Score (ASPECTS) by non-contrast computed tomography (CT-ASPECTS stratum) and diffusion-weighted imaging (DWI-ASPECTS stratum) may impact the efficacy of endovascular therapy (EVT) in patients with a large ischemic core.
Methods:
The RESCUE-Japan LIMIT (Recovery by Endovascular Salvage for Cerebral Ultra-acute Embolism Japan–Large IscheMIc core Trial) was a multicenter, open-label, randomized clinical trial that evaluated the efficacy and safety of EVT in patients with ASPECTS of 3–5. CT-ASPECTS was prioritized when both CT-ASPECTS and DWI-ASPECTS were measured. The effects of EVT on the modified Rankin Scale (mRS) score at 90 days were assessed separately for each stratum.
Results:
Among 183 patients, 112 (EVT group, 53; No-EVT group, 59) were in the CT-ASPECTS stratum and 71 (EVT group, 40; No-EVT group, 31) in the DWI-ASPECTS stratum. The common odds ratio (OR) (95% confidence interval) of the EVT group for one scale shift of the mRS score toward 0 was 1.29 (0.65–2.54) compared to the No-EVT group in CT-ASPECTS stratum, and 6.15 (2.46–16.3) in DWI-ASPECTS stratum with significant interaction between treatment assignment and mode of imaging study (P=0.002). There were significant interactions in the improvement of the National Institutes of Health Stroke Scale score at 48 hours (CT-ASPECTS stratum: OR, 1.95; DWIASPECTS stratum: OR, 14.5; interaction P=0.035) and mortality at 90 days (CT-ASPECTS stratum: OR, 2.07; DWI-ASPECTS stratum: OR, 0.23; interaction P=0.008).
Conclusion
Patients with ASPECTS of 3–5 on MRI benefitted more from EVT than those with ASPECTS of 3–5 on CT.
