A knowledge-based simple education program for patients with epilepsy in Japan: Effects sustained after the program implementation.

PURPOSE: To investigate the effects of an original education program on patients with epilepsy (PWE). The effects on knowledge about epilepsy, attitude to epilepsy, depression scales, and quality of life were investigated. METHOD: Thirty-five PWE participated in a lecture-style educational program using an original knowledge-oriented textbook. All patients were administered a total of four rating scales: the Knowledge about Epilepsy Scale (KES), the Attitude toward Epilepsy Scale (AES), and the Japanese version of the Quality of Life in Epilepsy Inventory (QOLIE-31-P), the Beck Depression Inventory (BDI). The KES and AES of patients (pKES and pAES) were compared to those of medical students (St) and residents (Rd). RESULTS: After education, pKES improved and showed significant differences among pre-and post-education and six months later. Before education, pKES was inferior to St and Rd. However, after education, pKES changed and became superior to St and Rd. Six months later, the advantage was lost, but not significantly. PAES also improved after education, with significant differences before, after, and six months later after education. PAES was statistically inferior to St and Rd before education, but the difference disappeared after education, and the effect persisted after six months. The non-depressed (BDI < 20) and depressed groups (BDI â‰§ 20) improved in the KES after education. About the AES, the non-depressive group has a statistical tendency, but not the depressive group. At six months, the depressed group's AES is significantly lower than the non-depressed group. CONCLUSION: While correct knowledge about epilepsy can improve attitudes and perceptions of epilepsy in PWE, special measures are needed for PWE with depression.

A Japanese family with dystonia due to a pathogenic variant in SGCE.

Dystonia (DYT) is a heterogeneous neurological disorder, and there are many types of DYT depending on the responsible genes. DYT11 is an autosomal dominant DYT caused by functional variants in the SGCE gene. We examined a Japanese patient with myoclonic dystonia. By using exome analysis, we identified a rare variant in the SGCE gene, NM_003919.3: c.304C > T [Arg102*], in this patient. Therefore, this patient has been molecularly diagnosed with DYT11. By Sanger sequencing, we confirmed that this variant was paternally inherited in this patient. By allele-specific PCR, we confirmed that the maternally inherited normal allele of SGCE was silenced, and only the paternally inherited variant allele was expressed in this patient. Despite the pathogenicity, identical variants have been recurrently reported in eight independent families from different ethnicities, suggesting recurrent mutations at this mutational hotspot in SGCE.

Optimising first- and second-line treatment strategies for untreated major depressive disorder - the SUN☺D study: a pragmatic, multi-centre, assessor-blinded randomised controlled trial.

BACKGROUND: For patients starting treatment for depression, current guidelines recommend titrating the antidepressant dosage to the maximum of the licenced range if tolerated. When patients do not achieve remission within several weeks, recommendations include adding or switching to another antidepressant. However, the relative merits of these guideline strategies remain unestablished. METHODS: This multi-centre, open-label, assessor-blinded, pragmatic trial involved two steps. Step 1 used open-cluster randomisation, allocating clinics into those titrating sertraline up to 50 mg/day or 100 mg/day by week 3. Step 2 used central randomisation to allocate patients who did not remit after 3 weeks of treatment to continue sertraline, to add mirtazapine or to switch to mirtazapine. The primary outcome was depression severity measured with the Patient Health Questionnaire-9 (PHQ-9) (scores between 0 and 27; higher scores, greater depression) at week 9. We applied mixed-model repeated-measures analysis adjusted for key baseline covariates. RESULTS: Between December 2010 and March 2015, we recruited 2011 participants with hitherto untreated major depression at 48 clinics in Japan. In step 1, 970 participants were allocated to the 50 mg/day and 1041 to the 100 mg/day arms; 1927 (95.8%) provided primary outcomes. There was no statistically significant difference in the adjusted PHQ-9 score at week 9 between the 50 mg/day arm and the 100 mg/day arm (0.25 point, 95% confidence interval (CI), - 0.58 to 1.07, P = 0.55). Other outcomes proved similar in the two groups. In step 2, 1646 participants not remitted by week 3 were randomised to continue sertraline (n = 551), to add mirtazapine (n = 537) or to switch to mirtazapine (n = 558): 1613 (98.0%) provided primary outcomes. At week 9, adding mirtazapine achieved a reduction in PHQ-9 scores of 0.99 point (0.43 to 1.55, P = 0.0012); switching achieved a reduction of 1.01 points (0.46 to 1.56, P = 0.0012), both relative to continuing sertraline. Combination increased the percentage of remission by 12.4% (6.1 to 19.0%) and switching by 8.4% (2.5 to 14.8%). There were no differences in adverse effects. CONCLUSIONS: In patients with new onset depression, we found no advantage of titrating sertraline to 100 mg vs 50 mg. Patients unremitted by week 3 gained a small benefit in reduction of depressive symptoms at week 9 by switching sertraline to mirtazapine or by adding mirtazapine.

Association of HLA-A*31:01 Screening With the Incidence of Carbamazepine-Induced Cutaneous Adverse Reactions in a Japanese Population.

Importance: Carbamazepine, a commonly used antiepileptic drug, is one of the most common causes of cutaneous adverse drug reactions (cADRs) worldwide. The allele HLA-A*31:01 is reportedly associated with carbamazepine-induced cADRs in Japanese and European populations; however, the clinical utility of HLA-A*31:01 has not been evaluated. Objective: To assess the use of HLA-A*31:01 genetic screening to identify Japanese individuals at risk of carbamazepine-induced cADRs. Design, Setting, and Participants: This cohort study was conducted across 36 hospitals in Japan from January 2012 to November 2014 among 1202 patients who had been deemed suitable to start treatment with carbamazepine. Preemptive HLA-A*31:01 genetic screening was performed for 1187 participants. Patients who did not start treatment with carbamazepine or alternative drugs were excluded. Participants were interviewed once weekly for 8 weeks to monitor the development of cADRs. Data analysis was performed from June 8, 2015, to December 27, 2016. Exposures: Neuropsychiatrists were asked to prescribe carbamazepine for patients who tested negative for HLA-A*31:01 and alternative drugs for those who tested positive for HLA-A*31:01. Main Outcomes and Measures: Incidence of carbamazepine-induced cADRs. Results: Of the 1130 included patients who were prescribed carbamazepine or alternative drugs, the mean (range) age was 37.4 (0-95) years, 614 (54.3%) were men, and 198 (17.5%) were positive for HLA-A*31:01. Expert dermatologists identified 23 patients (2.0%) who had carbamazepine-induced cADRs, of which 4 patients required hospitalization. Drug-induced hypersensitivity syndrome was observed for 3 patients, maculopapular eruption for 9 patients, erythema multiforme for 5 patients, and an undetermined type of cADR for 6 patients. No patient developed Stevens-Johnson syndrome or toxic epidermal necrolysis. Compared with historical controls, the incidence of carbamazepine-induced cADRs was significantly decreased (for BioBank Japan data: incidence, 3.4%; odds ratio, 0.60; 95% CI, 0.36-1.00; P = .048; for the Japan Medical Data Centre claims database: incidence, 5.1%; odds ratio, 0.39; 95% CI, 0.26-0.59; P < .001). Conclusions and Relevance: Preemptive HLA-A*31:01 genetic screening significantly decreased the incidence of carbamazepine-induced cADRs among Japanese patients, which suggests that it may be warranted in routine clinical practice.

A change in electrographic activity and blood flow during interictal and postictal psychotic states in a patient with epilepsy.

We report a patient with epilepsy who experienced interictal and postictal psychoses. Her psychiatric symptoms consisted of grandiose and fantastic delusions during both psychotic states. During remission, electroencephalography showed bitemporal epileptiform discharges that were predominant in the right temporal region. Epileptiform discharges present during the psychotic states were predominant in the left temporal region. Single-photon emission computed tomography showed hyperperfusion in the left basal ganglia during the interictal psychotic state and hyperperfusion in the right temporal lobe and left basal ganglia during the postictal psychotic state. We suggest that the occurrence of postictal and interictal psychotic states in this patient were associated with a common change in electrographic activity and blood flow.

Therapeutic effect of nimesulide on colorectal carcinogenesis in experimental murine ulcerative colitis.

BACKGROUND: Patients with ulcerative colitis (UC) exhibit an increased risk for the development of cancer of the colon and rectum. Cyclooxygenase (COX)-2 inhibitors are known to suppress sporadic colorectal cancer, but it is unknown whether selective COX-2 inhibitors exhibit a preventive effect in UC-associated neoplasia. This study investigated the preventive effect of nimesulide, a selective COX-2 inhibitor, on colorectal carcinogenesis in an experimental model of murine UC. METHODS: Chronic colitis was induced in mice by administration of four cycles of dextran sulfate sodium (DSS) (each cycle: 5% DSS for 7 days and then distilled water for 14 days). The mice were killed 120 days after the completion of the fourth cycle. The mice were divided into the following five groups: group A served as a disease control; group B received a diet mixed with 400 p.p.m. of nimesulide during the whole period; group C received nimesulide during the four cycles of DSS administration (active phase); group D received nimesulide for 120 days from the end of the fourth cycle (remission phase); group E received no agents including DSS and served as a normal control. RESULTS: The incidence of dysplasia and/or cancer was 28%, 15%, 11.8%, 6.7% and 0% in groups A-E, respectively. In group D, nimesulide significantly suppressed the occurrence of dysplasia and/or cancer (P < 0.05). Strong COX-2 expression was detected by immunohistochemistry in cancer and dysplastic lesions while diffusely weak COX-2 expression was also found in the residual colon (i.e. lesion-free colon). The mucosal concentration of prostaglandin E(2) was significantly lower in groups B and D than in group A. CONCLUSIONS: The administration of the selective COX-2 inhibitor nimesulide (especially during the remission phase) exerts a suppressive effect on the development of dysplasia and/or cancer in a murine model of DSS-induced colitis. These findings may have relevance to long-standing UC in humans.

Evaluation of the effect of pyrrolidine dithiocarbamate in suppressing inflammation in mice with dextran sodium sulfate-induced colitis.

AIM: To evaluate the effect of pyrrolidine dithio-carbamate (PDTC; an NF-kappaB inhibitor) administered at low (50 mg/kg) and high (100 mg/kg) doses in suppressing colitis in mice with dextran sodium sulfate (DSS)-induced colitis. METHODS: Mice were divided into a DSS-untreated group (normal group), DSS-treated control group, DSS+PDTC-treated group I (low-dose group), and DSS+PDTC-treated group II (high-dose group). In each group, the disease activity index score (DAI score), intestinal length, histological score, and the levels of activated NF-kappaB and inflammatory cytokines (IL-1beta and TNF-alpha) in tissue were measured. RESULTS: The DSS+PDTC-treated group II exhibited suppression of shortening of intestinal length and reduction of DAI score. Activated NF-kappaB level and IL-1beta and TNF-alpha levels were significantly lower in DSS+PDTC-treated group II. CONCLUSION: These findings suggest that PDTC is useful for the treatment of ulcerative colitis.

Refractory ulcerative colitis accompanied with cytomegalovirus colitis and multiple liver abscesses: a case report.

Various hepato-biliary complications are an increased incidence in patients with inflammatory bowel disease, and portal bacteremia is well documented in patients with ulcerative colitis (UC). However, few reports mention UC in association with liver abscesses. Recently, there are several reports describing cytomegalovirus (CMV) infection in association with disease exacerbation and steroid refractoriness in patients with UC. Here we present a case of refractory UC accompanied with multiple liver abscesses and CMV colitis. The patient, a 72-year-old male, with a five-year history of repeated admissions to our hospital for UC, presented with an exacerbation of his UC. Sigmoidoscopy performed on admission suggested that his UC was exacerbated, then he was given prednisolone and mesalazine orally, and betamethasone enemas. However, he had exacerbated symptoms. Repeat sigmoidoscopy revealed multiple longitudinal ulcers and pseudopolyps in the rectosigmoid colon. Although immunohistochemical staining of biopsy specimens and the serum testing for antigenemia were negative on admission and after the repeat sigmoidoscopy, they became histologically positive for CMV. Nonetheless, the patient developed spiking fevers, soon after ganciclovir was administered. Laboratory studies revealed an increased white cell count with left shift, and Enterococcus fecalis grew in blood cultures. An abdominal computed tomography (CT) scan was obtained and the diagnosis of liver abscesses associated with UC was made, based on CT results. The hepatic abscesses were successfully treated with intravenous meropenem for 6 wk, without further percutaneous drainage. To our knowledge, this is the first reported case of multiple liver abscesses that develop during UC exacerbation complicated by CMV colitis.

Bupivacaine, but not tetracaine, protects against the in vitro ischemic insult of rat hippocampal CA1 neurons.

Neuroprotective actions of local anesthetics, bupivacaine and tetracaine, against the irreversible membrane dysfunction induced by in vitro ischemia were investigated. Intracellular recordings were made from hippocampal CA1 neurons in rat brain slice preparations. Oxygen and glucose deprivation (in vitro ischemia) produced a rapid depolarization after approximately 5 min of exposure. When oxygen and glucose were reintroduced, the membrane depolarized further and reached at 0 mV: the membrane showed no functional recovery (irreversible membrane dysfunction). Pretreatment with tetracaine or bupivacaine significantly prolonged the latency of rapid depolarization. Bupivacaine, but not tetracaine, restored the membrane potential after the reintroduction of oxygen and glucose. Tetracaine and bupivacaine depressed both field postsynaptic potentials and presynaptic volleys. The drugs also reduced the dV/dt of Ca(2+)-dependent spikes and the rapid rise of [Ca(2+)](i) induced by in vitro ischemia. Compared with tetracaine, bupivacaine markedly suppressed the resting K(+) conductance and the ATP-sensitive and Ca(2+)-dependent K(+) conductances. Moreover, in the presence of tetraethylammonium (TEA), a majority of CA1 neurons impaled with Cs acetate-filled electrodes showed complete or partial recovery of the membrane potential after reintroducing oxygen and glucose. These results suggest that the neuroprotective action of bupivacaine is mainly due to the suppression of the K(+) conductances.
