    Treatment of patients with clinically isolated syndrome (CIS) with disease modifying drugs including interferon β delays conversion to clinically definite multiple sclerosis (MS). However, CIS patients do not necessarily develop MS even after 20 years. Brain MRI lesions were required for CIS patients to include in clinical trials such as CHAMPS study and BENEFIT study. CIS patients with brain MRI lesions compatible to MS were considered as high risk to convert to MS in western countries. Previously we reported that asymptomatic enhancing brain lesions (AEBLs) were found in 9/23 (39.1%) of MS patients who had suffered at least one relapse in the preceding year or two relapses in the preceding 2 years, and the number of AEBLs per scan was 0.37, suggesting low disease activity of Japanese MS patients. We examined brain MRI findings in Japanese CIS patients and compared with those of Japanese MS patients at the first presentation. We reviewed brain MRI of 23 CIS visited our clinic from December 2007 to October 2010 who fulfilled the criteria proposed by Kappos et al. (2006) and Dalton et al (2002). Thirty two clinically definite MS (CDMS) patients fulfilled the first McDonald criteria (two or more attacks and objective clinical evidence of two or more lesions) proposed by Polman et al. (2005). Patients with neuromyelitis optica (NMO) and patients with NMO spectrum proposed by Wingerchuk et al. (2006) and Wingerchuk et al. (2007), respectively, were excluded. Patients with anti-aquaporin4 antibodies or with contiguous spinal cord lesion extending over three vertebral segments on MRI were also excluded. We could not obtain MRI of 11 patients with CDMS because of very long disease course, and 2 CIS and 13 CDMS patients had not been examined with MRI. So we examined 21 CIS and 8 CDMS patients at the first presentation using Paty criteria and Barkhof criteria. Eleven CIS patients did not meet any of the Barkhof criteria. Seven and 3 CIS patients met one and two of Barkhof

    Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder caused by mutation in the NF1 tumor-suppressor gene, and may sometimes manifest in a mosaic form. "Segmental NF1" is generally assumed to be the result of somatic mosaicism for a NF1 mutation, and patients with mosaic NF1 have typical features of NF1 limited to specific body segments. The clinical features of 58 patients (42 females and 16 males; aged 1-69 years; mean age, 23.4 years) with mosaic NF1 seen at the Jikei University Hospital during 2004-2007 and at the Jikei University Daisan Hospital during 2007-2011, were retrospectively studied. Somatic or gonosomal mosaicism was not investigated. Patients were classified into four groups: (i) pigmentary changes (café-au-lait spots and freckling) only (n = 32); (ii) neurofibromas only (n = 5); (iii) neurofibromas and pigmentary changes (n = 13); and (iv) solitary plexiform neurofibromas (n = 8). The area of involvement was variable. The majority of patients were asymptomatic, except patients with plexiform neurofibromas who presented most commonly with pain or tenderness. Lisch nodules were rarely seen. Only four of our 58 patients (6.9%) had specific NF1 complications, including language delay (n = 1) and bone deformity (n = 3). Two patients were ascertained through their children with generalized NF1. Patients with mosaic NF1 are at low risk of developing disease-associated complications, except patients with plexiform neurofibromas. However, they need to be aware of the small risk of having a child with generalized NF1. PMID:25041723

    The aim of this study was to examine the clinical characteristics of patients with gender identity disorder (GID) at a GID clinic in Japan. A total of 603 consecutive patients were evaluated at the GID clinic using clinical information and results of physical and neurological examinations. Using DSM-IV criteria, 579 patients (96.0%) were diagnosed with GID. Four patients were excluded for transvestic fetishism, eight for homosexuality, five for schizophrenia, three for personality disorders, and four for other psychiatric disorders. Among the GID patients, 349 (60.3%) were the female-to-male (FTM) type, and 230 (39.7%) were the male-to-female (MTF) type. Almost all FTM-type GID patients started to feel discomfort with their sex before puberty and were sexually attracted to females. The proportion of FTM patients who had experienced marriage as a female was very low, and very few had children. Therefore, FTM-type GID patients seem to be highly homogeneous. On the other hand, various patterns of age at onset and sexual attraction existed among MTF patients. Among the MTF-type GID patients, 28.3% had married as males and 18.7% had sired children. Thus, MTF-type GID patients seem to be more heterogeneous. PMID:17959255

    Hodgkin lymphoma (HL) is a rare subtype of malignant lymphoma in Japan, and there are few reports of HL in Japan in recent years. We retrospectively analyzed the clinical features of 139 patients with HL who were diagnosed and treated at our institution between 1997 and 2011. The median age at diagnosis was 34 years with 83 male. Of these patients, 83 (60 %) were early stage and 56 (40 %) were advanced-stage. Seventy-three patients (88 %) with early stage disease received ABVd followed by irradiation. All of the 56 advanced-stage patients received chemotherapy, mainly ABVd. The 5-year progression-free survival (PFS) rates and overall survival rates were 90 and 94 % in patients with early stage disease, and 71 and 90 % in those with advanced-stage disease. The PFS of patients with advanced-stage disease was significantly lower than those with early stage (p = 0.014). In conclusion, the outcomes of Japanese patients with HL in recent years were not improved as compared with the results of previous reports. We confirmed that patients with advanced-stage disease have lower PFS than those with early stage disease. Prospective studies are needed to establish novel treatment strategies to improve the outcome of HL patients, especially those with advanced disease. PMID:27086350

    Because of the potentially high mortality rate (6.5%) associated with bortezomib-induced lung disease (BILD) in Japanese patients with relapsed or refractory multiple myeloma, we evaluated the incidence, mortality and clinical features of BILD in a Japanese population. This study was conducted under the Risk Minimization Action Plan (RMAP), which was collaboratively developed by the pharmaceutical industry and public health authority. The RMAP consisted of an intensive dissemination of risk information and a recommended countermeasure to health-care professionals. All patients treated with bortezomib were consecutively registered in the study within 1 year and monitored for emerging BILD. Of the 1010 patients registered, 45 (4.5%) developed BILD, 5 (0.50%) of whom had fatal cases. The median time to BILD onset from the first bortezomib dose was 14.5 days, and most of the patients responded well to corticosteroid therapy. A retrospective review by the Lung Injury Medical Expert Panel revealed that the types with capillary leak syndrome and hypoxia without infiltrative shadows were uniquely and frequently observed in patients with BILD compared with those with conditions associated with other molecular-targeted anticancer drugs. The incidence rate of BILD in Japan remains high compared with that reported in other countries, but the incidence and mortality rates are lower than expected before the introduction of bortezomib in Japan. This study describes the radiographic pattern and clinical characterization of BILD in the Japanese population. The RMAP seemed clinically effective in minimizing the BILD risk among our Japanese population. PMID:24329927

    Bisphosphonate-related osteonecrosis of the jaw (BRONJ) affects quality of life and is an important problem for dentists. A Japanese position paper on BRONJ was published in 2010. The purpose of this study was to review clinical data on the treatment of BRONJ obtained at the Clinic of Oral and Maxillofacial Surgery, Tokyo Dental College, Chiba Hospital to further our understanding of this disease. A total of 13 patients (6 men and 7 women) were included. All the patients included in this study had received Bisphosphonate (BP) therapy and had BRONJ. Five of them (38.5%) had received oral BP therapy for osteoporosis, while the remaining 8 (61.5%) had received parenteral BP therapy for bone metastases from breast or prostate cancer. Osteoporosis patients were treated with risedronate or alendronate. Breast or prostate cancer patients were treated with zoledronate. Two patients with rheumatoid arthritis were treated with corticosteroid. Three patients had diabetes mellitus. Eleven patients were treated with antibiotics, while 5 underwent surgical treatment. Discontinuation of BP was recorded in 7 patients during dental treatment. Sequestration was observed in 6 patients during an 11-month follow-up. Eventually, healing and improvement of the oral mucosa were observed in 3 patients. The current standard treatment for BRONJ does not always provide good results. It is necessary to accumulate further clinical data to establish more effective treatment strategies for BRONJ. PMID:23903583

    Background Liraglutide was first released in Japan as a long-acting once-daily glucagon-like peptide-1 receptor agonist. The maximum dose in Japan is 0.9 mg/day, which is half of that used in the United States and the European Union (1.8 mg/day). The efficacy of this maximum allowable dose of liraglutide for Japanese patients and the profiles of those patients for whom this agent should be recommended remain unclear. Methods This study aimed to examine the effective use of liraglutide in Japanese type 2 diabetic patients. We administered liraglutide to 60 patients, who had been managed with oral hypoglycemic agents or diet and exercise therapy only, during a period of 6 months. Results Though HbA1c levels significantly decreased, by approximately 1.5%, after 6 months of liraglutide administration, no significant changes in body weights were observed. The 0.6 mg dose was effective in approximately 40% of patients. In contrast, the effects of a dose increase from 0.6 mg to 0.9 mg were small. The greatest efficacy, as shown by a 2.5% HbA1c decrease, was achieved in non-obese patients. Thus, efficacy decreased as the degree of obesity increased. In addition, efficacy was higher in patients who had a diabetes duration of less than 10 years and was also higher in the group that had a low sulfonylurea (SU) index, when we define the SU index as mg/glimepiride × years of treatment. Conclusions As appetite suppressions and associated decreases in body weights were not observed in obese patients, the efficacy of liraglutide at 0.9 mg did not appear to be high. Rather, it appeared to be highly effective for patients who were non-obese and for whom amelioration of blood glucose elevations could be anticipated via the stimulation of insulin secretion. Therefore, we found that liraglutide at doses of 0.9 mg was highly effective in non-obese patients who were in the early stages of diabetes and was particularly effective in patients who had not yet been administered SU agents

    Purpose To evaluate the clinical features and investigate their relationship with visual function in Japanese patients with acute zonal occult outer retinopathy (AZOOR). Methods Fifty-two eyes of 38 Japanese AZOOR patients (31 female and 7 male patients; mean age at first visit, 35.0 years; median follow-up duration, 31 months) were retrospectively collected: 31 untreated eyes with good visual acuity and 21 systemic corticosteroid-treated eyes with progressive visual acuity loss. Variables affecting the logMAR values of best-corrected visual acuity (BCVA) and the mean deviation (MD) on Humphrey perimetry at initial and final visits were examined using multiple stepwise linear regression analysis. Results In untreated eyes, the mean MD at the final visit was significantly higher than that at the initial visit (P = 0.00002). In corticosteroid-treated eyes, the logMAR BCVA and MD at the final visit were significantly better than the initial values (P = 0.007 and P = 0.02, respectively). The final logMAR BCVA was 0.0 or less in 85% of patients. Variables affecting initial visual function were moderate anterior vitreous cells, myopia severity, and a-wave amplitudes on electroretinography; factors affecting final visual function were the initial MD values, female sex, moderate anterior vitreous cells, and retinal atrophy. Conclusions Our data indicated that visual functions in enrolled patients significantly improved spontaneously or after systemic corticosteroids therapy, suggesting that Japanese patients with AZOOR have good visual outcomes during the follow-up period of this study. Furthermore, initial visual field defects, gender, anterior vitreous cells, and retinal atrophy affected final visual functions in these patients. PMID:25919689

    Recently, the reemergence of vitamin D deficiency in developed countries has been pointed out. Vitamin D deficiency is diagnosed based on the serum 25-hydroxyvitamin D (25OHD) level. However, its normal range is still controversial, making the diagnosis of vitamin D deficiency difficult. Here, we present seven Japanese patients diagnosed with vitamin D deficiency. Three patients complained of leg bowing, and the other four of tetany. The patients with leg bowing were toddlers. Radiographic surveys demonstrated evidence of rickets. Laboratory findings showed decreased levels of serum inorganic phosphorus and increased levels of alkaline phosphatase (ALP) and intact-parathyroid hormone (iPTH). The serum levels of 25OHD were relatively low, ranging from 13 to 15.2 ng/ml. Of the patients with tetany, three were young infants. Laboratory findings showed decreased levels of serum calcium and increased levels of ALP and iPTH. The serum levels of 25OHD were markedly decreased (below 8 ng/ml). Thus, these results indicate that relatively low levels of 25OHD can cause rickets, a symptom of vitamin D deficiency, and that clinicians should therefore carefully evaluate the levels of 25OHD.

    Aim. Cognitive impairment in schizophrenia strongly relates to social outcome and is a good candidate for endophenotypes. When we accurately measure drug efficacy or effects of genes or variants relevant to schizophrenia on cognitive impairment, clinical factors that can affect scores on cognitive tests, such as age and severity of symptoms, should be considered. To elucidate the effect of clinical factors, we conducted multiple regression analysis using scores of the Continuous Performance Test Identical Pairs Version (CPT-IP), which is often used to measure attention/vigilance in schizophrenia. Methods. We conducted the CPT-IP (4-4 digit) and examined clinical information (sex, age, education years, onset age, duration of illness, chlorpromazine-equivalent dose, and Positive and Negative Symptom Scale (PANSS) scores) in 126 schizophrenia patients in Japanese population. Multiple regression analysis was used to evaluate the effect of clinical factors. Results. Age, chlorpromazine-equivalent dose, and PANSS-negative symptom score were associated with mean d′ score in patients. These three clinical factors explained about 28% of the variance in mean d′ score. Conclusions. As conclusion, CPT-IP score in schizophrenia patients is influenced by age, chlorpromazine-equivalent dose and PANSS negative symptom score. PMID:22966454

    It is widely accepted that selective serotonin reuptake inhibitors (SSRIs) require 2 to 4 weeks of administration before improvements in emotional symptoms of depression are seen. We evaluated whether early monitoring of Hamilton Rating Scale for Depression (HAMD) scores in patients treated with the SSRI fluvoxamine could predict antidepressant response, and also assessed the relationship between the onset of clinical response following the start of fluvoxamine administration and its plasma concentration. Twelve depressed patients (baseline HAMD score ≥15) received an initial dose of fluvoxamine (50 mg/d) followed by an optimized maintenance dose according to their clinical symptoms after 7 d. HAMD scores and plasma drug concentrations were determined at 7 and 28 d after the first administration. There were 7 responders and 5 non-responders on day 28, as evaluated by HAMD scores. The HAMD score for the responders was significantly lower than that for the non-responders on day 7 (mean±S.D., 11.6±6.1 vs. 26.6±6.5, p=0.006). Thus, the reduction in HAMD score on day 7 was clearly divided between responders and non-responders. On day 28, the plasma concentration of fluvoxamine in responders was lower than that in non-responders (14.2±10.5 ng/ml vs. 44.2±28.1 ng/ml, p=0.051). Furthermore, receiver operating characteristic curve analysis conducted on day 28 revealed an upper concentration threshold of 28.2 ng/ml (p=0.042), with none in the responder group above that level. Our results suggest that HAMD score after the first week of treatment with fluvoxamine and the upper threshold of plasma drug concentration could predict whether a patient is a non-responder.

    Paget's disease of bone (PDB) is a chronic disorder characterized by localized bone regions with excessive bone turnover. Although oral risedronate (17.5 mg daily for 8 weeks) was recently approved in Japan, its efficacy is not well understood. We retrospectively examined the efficacy of oral risedronate in PDB patients in a clinical setting. Eleven patients whose serum alkaline phosphatase (ALP) level exceeded the upper limit of the normal range were treated. Patients whose ALP levels normalized and remained so for 12 months after therapy initiation were defined as responders. Treatment was repeated if bone pain recurred or if serum ALP levels increased at least 25% above the nadir. Six patients (55%) were responsive to the therapy. A higher prevalence of skull lesions, higher serum calcium levels at treatment initiation and antecedent treatments of bisphosphonates were predictors of resistance against the therapy. Fresh frozen serum samples obtained from some treatment sessions were evaluated for metabolic bone markers such as bone-specific ALP (BAP), type I procollagen N-terminal pro-peptide (PINP), N-treminal crosslinking telopeptide of type I collagen and C-treminal crosslinking telopeptide of type I collagen (CTX). A significant reduction of P1NP preceded that of serum ALP levels in the responders, which was followed by a similar occurrence for BAP and osteocalcin (BGP) levels. A temporary decrease in CTX levels was noted. No significant changes in markers (including ALP level) were observed in non-responder and repeat-treatment groups. P1NP levels may be more useful than ALP levels in assessing treatment efficacy. Repeat treatment effectiveness for the repeat-treatment group was limited. PMID:25319558

    Facioscapulohumeral muscular dystrophy 2 (FSHD2) is a genetic muscular disorder characterized by DNA hypomethylation on the 4q-subtelomeric macrosatellite repeat array, D4Z4. FSHD2 is caused by heterozygous mutations in the gene encoding structural maintenance of chromosomes flexible hinge domain containing 1 (SMCHD1). Because there has been no study on FSHD2 in Asian populations, it is not known whether this disease mechanism is widely seen. To identify FSHD2 patients with SMCHD1 mutations in the Japanese population, bisulfite pyrosequencing was used to measure DNA methylation on the D4Z4 repeat array, and in patients with DNA hypomethylation, the SMCHD1 gene was sequenced by the Sanger method. Twenty patients with D4Z4 hypomethylation were identified. Of these, 13 patients from 11 unrelated families had ten novel and one reported SMCHD1 mutations: four splice-site, two nonsense, two in-frame deletion, two out-of-frame deletion, and one missense mutations. One of the splice-site mutations was homozygous in the single patient identified with this. In summary, we identified novel SMCHD1 mutations in a Japanese cohort of FSHD2 patients, confirming the presence of this disease in a wider population than previously known. PMID:27061275

    It is well known that silent myocardial ischemia (SMI) often complicates patients with cerebral infarction and that stroke patients often die of ischemic heart disease. Therefore, it is considered important to treat myocardial ischemia in stroke patients. This study investigated SMI complicating Japanese patients with fresh stroke, using (99m)Tc-tetrofosmin myocardial scintigraphy with pharmacologic stress testing to elucidate their clinical manifestations. This study included 41 patients (26 men, mean age 76.0 ± 10.7 years) with acute cerebral infarction and no history of coronary artery disease. All patients underwent (99m)Tc-tetrofosmin myocardial scintigraphy with intravenous administration of adenosine to diagnose SMI. Of the 41 patients, myocardial ischemia was confirmed in 17 patients (41.5%). Atherosclerotic etiology was the major cause of stroke in the ischemia(+) group and embolic origin was the major cause in the ischemia(-) group. Patients with myocardial ischemia had a higher incidence of diabetes mellitus (52.9 vs 20.8%; P = 0.0323) and more than two conventional cardiovascular risk factors (64.7 vs 25.0%; P = 0.0110) compared with the nonischemic patients. Infarction subtype of atherosclerotic origin was an independent positive predictor of asymptomatic myocardial ischemia in patients with stroke. These findings indicate that the prevalence of asymptomatic myocardial ischemia is relatively high, especially in patients with stroke of atherosclerotic origin. Therefore, it is beneficial for us to narrow the target population who are at the highest risk when screening for SMI in Japanese patients with acute cerebral infarction. PMID:22124530

    A double-blind parallel group comparison design clinical study was conducted in Japanese patients with mild to moderate erectile dysfunction to investigate the efficacy of a supplement containing Pycnogenol® and L-arginine. Subjects were instructed to take a supplement (Pycnogenol® 60 mg/day, L-arginine 690 mg/day and aspartic acid 552 mg/day) or an identical placebo for 8 weeks, and the results were assessed using the five-item erectile domain (IIEF-5) of the International Index of Erectile Function. Additionally, blood biochemistry, urinalysis and salivary testosterone were measured. Eight weeks of supplement intake improved the total score of the IIEF-5. In particular, a marked improvement was observed in 'hardness of erection' and 'satisfaction with sexual intercourse'. A decrease in blood pressure, aspartate transaminase and γ-glutamyl transpeptidase (γ-GTP), and a slight increase in salivary testosterone were observed in the supplement group. No adverse reactions were observed during the study period. In conclusion, Pycnogenol® in combination with L-arginine as a dietary supplement is effective and safe in Japanese patients with mild to moderate erectile dysfunction. PMID:21618639

    Autoimmune autonomic ganglionopathy (AAG) is a rare acquired channelopathy that is characterized by pandysautonomia, in which autoantibodies to ganglionic nicotinic acetylcholine receptors (gAChR) may play a central role. Radioimmunoprecipitation (RIP) assays have been used for the sensitive detection of autoantibodies to gAChR in the serum of patients with AAG. Here, we developed luciferase immunoprecipitation systems (LIPS) to diagnose AAG based on IgGs to both the α3 and β4 gAChR subunits in patient serum. We reviewed the serological and clinical data of 50 Japanese patients who were diagnosed with AAG. With the LIPS testing, we detected anti-α3 and -β4 gAChR antibodies in 48% (24/50) of the patients. A gradual mode of onset was more common in the seropositive group than in the seronegative group. Patients with AAG frequently have orthostatic hypotension and upper and lower gastrointestinal tract symptoms, with or without anti-gAChR. The occurrence of autonomic symptoms was not significantly different between the seropositive and seronegative group, with the exception of achalasia in three patients from the seropositive group. In addition, we found a significant overrepresentation of autoimmune diseases in the seropositive group and endocrinological abnormalities as an occasional complication of AAG. Our results demonstrated that the LIPS assay was a useful novel tool for detecting autoantibodies against gAChR in patients with AAG. PMID:25790156

    No clinical evidence on the efficacy and safety of eribulin monotherapy has been obtained by a prospective clinical study in patients with metastatic breast cancer (MBC) who had well-defined taxane resistance. The present Phase II, multicenter, single-arm, open-label study aimed to obtain the evidence. Japanese female patients, aged 33-74 years who had the metastasis of taxane-resistant and histopathologically confirmed breast cancer, received eribulin mesylate 1.4 mg/m(2) (equivalent to eribulin 1.23 mg/m(2) [expressed as free base]) as a 2- to 5-min intravenous infusion on days 1 and 8 of each 21-day cycle. The primary endpoint was the clinical benefit rate (CBR) [complete response (CR), partial response (PR), and long-term stable disease (LSD) ≥24 weeks]. A total of 51 patients underwent chemotherapy cycles (median 4; range 1-42 cycles). The CBR was 39.2 % (CR 2.0 %; PR 23.5 %; and LSD 13.7 %), and the rate of progressive disease was 49.0 %. The median progression-free survival and the median overall survival were 3.6 months [95 % confidence interval (CI) 2.6-4.6 months] and 11.7 months (95 % CI 9.2-14.2 months), respectively. Grade 3 or greater adverse events were leukopenia (23.5 %), neutropenia (35.3 %), anemia (5.9 %), and febrile neutropenia (7.8 %). The incidences of grade 3 and 4 peripheral sensory neuropathy were 2.0 and 0 %, respectively. Eribulin showed a clinically manageable tolerability profile by dose adjustments or symptomatic treatment. Eribulin was effective and well tolerated in heavily pretreated patients with MBC who had well-defined taxane resistance, thus providing a potential therapeutic option in the clinical settings.

    Abstract We aimed to elucidate the epidemiology, patient demographics, and clinical outcomes of hospitalization for hypoglycemia in diabetic patients using a Japanese large-scale database. We conducted a retrospective study using a national inpatient database of acute care hospitals in Japan. Diabetic patients ages ≥15 years with hypoglycemia as a main diagnosis for hospitalization were eligible. We estimated the annual number of hospitalizations in Japan and compared the annual admission rate by age and treatment groups. We also analyzed the association between patient characteristics and in-hospital mortality. Among 22.7 million discharge records from July 2008 and March 2013, a total of 25,071 patients were eligible. The mean age was 73.4 years, and the mean body mass index (BMI) was 22.3 kg/m2. The estimated annual hospitalization for hypoglycemia in Japan was ∼20,000. Annual admission rates for hypoglycemia per 1000 diabetic patients and 1000 diabetic patients receiving insulin or oral hypoglycemic agents were 2.1 and 4.1, respectively. Patients <40 years and >70 years old were at a higher risk of hospitalization. In-hospital mortality was 3.8%, and risk factors associated with poor survival were male sex, older age, lower bed capacity, community hospital, low BMI, coma at admission, and higher Charlson Comorbidity Index. To prevent severe hypoglycemia that leads to death and complications, individualized and careful glycemic control are important, especially in very old or young patients and in those with comorbid conditions or low BMI.

    Abstract Objectives: To compare the efficacy and safety of certolizumab pegol (CZP) with and without loading dose (LD) in a post-hoc analysis of two Japanese clinical studies. Methods: Data from the double-blind trials (DBT) J-RAPID and HIKARI, and their open-label extension (OLE) studies, were used. Patients randomized to CZP 200 mg every 2 weeks (Q2W) groups starting with LD (400 mg Weeks 0/2/4; LD group; J-RAPID: n = 82, HIKARI: n = 116) and patients randomized to placebo groups who subsequently started CZP Q2W without LD in the OLEs (No-LD group; J-RAPID: n = 61, HIKARI: n = 99) were analyzed. Efficacy and pharmacokinetics were assessed during 24 weeks. Adverse events were reported from all studies. Results: In both trials, the LD groups showed more rapid initial ACR20/50/70 kinetics, and maintained higher ACR50/70 responses until 24 weeks, compared with the No-LD groups. Anti-CZP antibody development was less frequent in the LD groups (J-RAPID: 1.2% versus 4.9%; HIKARI: 17.2% versus 27.3%). Similar safety profiles were reported between LD and No-LD groups (any AEs: 281.8 versus 315.7 [J-RAPID], 282.6 versus 321.3 [HIKARI] [incidence rate/100 patient-years]). Conclusions: Despite limitations, including comparing DBT and OLE studies, these results suggest that a CZP LD improves clinical response in active rheumatoid arthritis without altering the safety profile.

    Objective. The aim of this study was to compare efficacy outcomes of initial treatment with adalimumab + MTX vs adalimumab addition following 26 weeks of MTX monotherapy in Japanese early RA patients naive to MTX with high disease activity. Methods. Patients completing the 26-week, randomized, placebo-controlled trial of adalimumab + MTX were eligible to receive 26 weeks of open-label adalimumab + MTX. Patients were assessed for mean change from baseline in the 28-joint DAS with ESR (DAS28-ESR) and modified total Sharp score (mTSS), and for the proportions of patients achieving clinical, functional or radiographic remission. Results. Of 333 patients assessed, 278 (137 from the initial adalimumab + MTX and 141 from the initial placebo + MTX groups) completed the 52-week study. Significant differences in clinical and functional parameters observed during the 26-week blinded period were not apparent following the addition of open-label adalimumab to MTX. Open-label adalimumab + MTX slowed radiographic progression through week 52 in both groups, but patients who received adalimumab + MTX throughout the study exhibited less radiographic progression than those who received placebo + MTX during the first 26 weeks (mean ΔmTSS at week 52 = 2.56 vs 3.30, P < 0.001). Conclusion. Delayed addition of adalimumab in Japanese MTX-naive early RA patients did not impact clinical and functional outcomes at week 52 compared with the earlier addition of adalimumab. However, the accrual of significant structural damage during blinded placebo + MTX therapy contributed to the persistence of differences between the treatment strategies, suggesting that Japanese patients at risk for aggressive disease should benefit from the early inclusion of adalimumab + MTX combination therapy.

    Clinical features of high risk brain arteriovenous malformations (BAVMs) are well characterized. However, pathological evidences about the differences that are possessed by high risk patients are still lacking. We reviewed archived routine hematoxylin-eosin specimens from a total of 54 surgical treated BAVMs. The histopathological features in nidus were semi-quantitatively analyzed. We obtained the pathological differences of BAVMs nidus between several clinical features. Among the analyzed pathological features, the significant differences were observed in degree of venous enlargement and intimal hyperplasia. Juvenile, female, diffuse nidus, high Spetzler-Martin grade, and low flow patients had a lesser degree of those parameters compared to adult, male, compact nidus, low Spetzler-Martin grade and high flow patients. High risk profiles of BAVMs patients were well-reflected in the nidus pathology. Therefore, juvenile, female, diffuse nidus, and low flow in Japanese BAVMs patients might have different vascular remodeling process that predispose to higher tendency of hemorrhage. PMID:27053330

    Lenvatinib significantly prolonged progression-free survival (PFS) versus placebo in patients with radioiodine-refractory differentiated thyroid cancer (RR-DTC) in the phase 3 Study of (E7080) Lenvatinib in Differentiated Cancer of the Thyroid (SELECT) trial. This subanalysis evaluated the efficacy and safety of lenvatinib in Japanese patients who participated in SELECT. Outcomes for Japanese patients (lenvatinib, n = 30; placebo, n = 10) were assessed in relationship to the SELECT population (lenvatinib, n = 261; placebo, n = 131). The primary endpoint was PFS; secondary endpoints included overall survival, overall response rate, and safety. Lenvatinib PFS benefit was shown in Japanese patients (median PFS: lenvatinib, 16.5 months; placebo, 3.7 months), although significance was not reached, presumably due to sample size (hazard ratio, 0.39; 95% confidence interval, 0.10-1.57; P = 0.067). Overall response rates were 63.3% and 0% for lenvatinib and placebo, respectively. No significant difference was found in overall survival. The lenvatinib safety profile was similar between the Japanese and overall SELECT population, except for higher incidences of hypertension (any grade: Japanese, 87%; overall, 68%; grade ≥3: Japanese, 80%; overall, 42%), palmar-plantar erythrodysesthesia syndrome (any grade: Japanese, 70%; overall, 32%; grade ≥3: Japanese, 3%; overall, 3%), and proteinuria (any grade: Japanese, 63%; overall, 31%; grade ≥3: Japanese, 20%; overall, 10%). Japanese patients had more dose reductions (Japanese, 90%; overall, 67.8%), but fewer discontinuations due to adverse events (Japanese, 3.3%; overall, 14.2%). There was no difference in lenvatinib exposure between the Japanese and overall SELECT populations after adjusting for body weight. In Japanese patients with radioiodine-refractory differentiated thyroid cancer, lenvatinib showed similar clinical outcomes to the overall SELECT population.

    The purpose of this study is to report the neuroradiological manifestations of hereditary hemorrhagic telangiectasia (HHT). One hundred and thirty-nine Japanese HHT patients (73 men and 66 women, aged 2–78 years) were included in this study. Diagnosis of HHT was based on genetic analysis and/or clinical diagnosis of Curaçao. They included 68 HHT1 and 37 HHT2 patients. Essentially, all patients underwent brain magnetic resonance imaging (MRI) and pulmonary computed tomography (CT). Contrast enhanced studies of brain MRI and hepatic CT were performed in a subset of patients. Catheter cerebral angiography was performed when indicated. Their neuroradiological features were reviewed retrospectively. Various imaging abnormalities were found. Brain arteriovenous malformations (AVMs) were observed in 27/136 patients (19.9%, 21 patients with HHT1 and 1 patient with HHT2). Pulmonary arteriovenous fistulas (AVFs) were found in 73/137 patients (65.2%, 45 patients with HHT1 and 6 patients with HHT2). Cerebral infarction and brain abscess were found in 17 patients and 3 patients with pulmonary AVFs, respectively. T1 high lesions in the basal ganglia suggestive of porto-venous shunts were observed in 51/136 patients (37.5%, 9 patients with HHT1 and 28 patients with HHT2). Hepatic AVMs were observed in 61/136 patients (44.9%, 15 patients in HHT1 and 29 patients in HHT2). Brain AVMs and pulmonary AVFs were more common in HHT1 than in HHT2 (both p < 0.01), but hepatic AVMs were conversely more common in HHT2 than in HHT1 (p < 0.01). In conclusion, HHT patients present with a variety of neuroradiological manifestations, which are related to substantial causes of morbid-mortality in HHT. PMID:26041630

    Background In the FIRE-3 trial, overall survival (OS) was significantly longer in patients treated with FOLFIRI plus cetuximab (C-mab) than in those treated with FOLFIRI plus bevacizumab (Bev), but progression-free survival (PFS) was not significantly different. This may be associated with the deepness of response (DpR) in patients treated with FOLFIRI plus C-mab. We aimed to evaluate the relationship between clinical outcome and DpR in metastatic colorectal cancer (mCRC) patients treated with second-line FOLFIRI plus C-mab. Methods A total of 112 patients with histopathologically confirmed mCRC treated with second-line FOLFIRI in combination with C-mab (N=42) or Bev (N=70) were retrospectively enrolled between October 2008 and June 2013. The relationship between DpR and clinical outcome in patients treated with FOLFIRI plus C-mab or Bev was determined. Results Forty-two patients treated with FOLFIRI plus C-mab had a mean DpR of 6.1% (inter-quartile range: −13.7%, 20.8%) and a minimum DpR of −62.7%. On the other hand, 70 patients treated with FOLFIRI plus Bev had a mean DpR of 0% (interquartile range: −16%, 10%) and a minimum DpR of −111%. DpR ≥30% was associated with significantly longer OS and PFS when compared with DpR ≤30% in patients given FOLFIRI plus C-mab. DpR (≥30%) was independently associated with prolongation of OS and PFS. In patients treated with FOLFIRI plus C-mab, there was a moderate positive correlation between DpR and clinical outcomes (OS: r=0.51, P<0.001; PFS: r=0.54, P<0.001). Conclusion FOLFIRI plus C-mab yielded a stronger correlation between DpR and clinical outcomes. These results indicate the potential of DpR as a new measure of efficacy in mCRC patients treated with second-line chemotherapy plus C-mab. PMID:26273206

    Recently a putative ALD gene containing a striking homology with peroxisomal membrane protein (PMP70) has been identified. Besides childhood ALD, various clinical phenotypes have been identified with the onset in adolescence or adulthood (adrenomyeloneuropathy (AMN), adult cerebral ALD or cerebello-brainstem dominant type). The different clinical phenotypes occasionally coexist even in the same family. To investigate if there is a correlation between the clinical phenotypes and genotypes of the mutations in the ALD gene, we have analyzed 43 Japanese ALD patients. By Southern blot analysis, we identified non-overlapping deletions of 0.5 kb to 10.4 kb involving the ALD gene in 3 patients with adult onset cerebello-brainstem dominant type. By detailed direct sequence analysis, we found 4 patients who had point mutations in the coding region. An AMN patient had a point mutation leading to {sup 266}Gly{r_arrow}Arg change, and another patient with adult cerebral ALD had a 3 bp deletion resulting in the loss of glutamic acid at codon 291, which is a conserved amino acid both in ALD protein and PMP70. Two patients with childhood ALD had point mutations leading to {sup 507}Gly{r_arrow}Val, and {sup 518}Arg{r_arrow}Gln, respectively. Since amino acids from 507 to 520 are highly conserved as ATP-binding cassette transporter proteins, mutations in this region are expected to result in dramatic changes of the function of this protein. Although there is a tendancy for mutation in childhood ALD to be present within the ATP-binding site motif, we found two adult patients who had large deletions involving the region. Taken together, strong correlation between genotypes and clinical phenotypes is unlikely to exist, and some other modifying factors might well play an important role for the clinical manifestations of ALD.

    In this study, we report the clinical characteristics of elderly Japanese patients with severe burns. We studied the clinical features of 76 adult patients with severe burns, 35 of whom (46.1%) were ≥65 years old. We evaluated the characteristics of patients with respect to each type of burn. In addition, we studied the rate of death and survival in the elderly and also between the elderly and non-elderly patients. The following parameters were either assessed or compared between the elderly and non-elderly: gender, average age, vital signs (Glasgow Coma Scale, systolic blood pressure, heart rate and respiratory rate) and PaO(2)/FiO(2) (P/F) ratio at admission, cause of burn and a history of physical or psychiatric disease. Further, we investigated whether the burn was caused by attempting suicide and determined the percent total body surface area (%TBSA), second- and third-degree burn area, burn index (BI), prognostic burn index (PBI), presence of tracheal burns, presence of alcohol intoxication and overdose poisoning, presence of tracheal intubation, outcome and cause of death. The male:female ratio of the elderly patients was 17:18 (average age, 78.1 (8.2) years). Burns were mostly caused by flame (26/35), followed by scalding (8/35). Ten patients had attempted suicide. The %TBSA, second-degree burn area, third-degree burn area, BI and PBI, respectively were 46.6% (26.7%), 15.3% (19.0%), 35.6% (26.0%), 41.1 (25.2) and 119.2 (25.9). Of the 35 patients, 23 died. The notable characteristics of the elderly patients who died were flame as the cause of the burns: high %TBSA, BI and PBI, and a high rate of tracheal intubation. Elderly patients constituted approximately 45% of our study population. Most burns were caused by flames. The incidence of accidental bathtub-related burns was higher and that of suicide attempts was lower in the elderly patients, as compared with the non-elderly patients. Severe burns were fatal for elderly patients. Therefore, elderly

    We measured the quality of life of Japanese patients with acne using the Japanese version of Skindex-16, a semantically equivalent and validated translation of the original version produced by Chren et al. A total of 210 acne patients were enrolled in this study. The results showed that patients with acne experienced more severe emotional effects from their skin disease than functional or symptomatic effects. The scores for emotional aspects were related to the severity of the patients' acne following a prescribed scale, but the scores were high even when the patients only had a few comedones. Akaike's information criterion showed that the scores for symptoms were related to the severity of the patients' acne, and the patients' emotions were related to the interval between clinic visits. To improve patients' quality of life, treatment of comedones should be fully respected. In addition, dermatologists should encourage patients to visit clinics regularly to help them improve the emotional aspects of their quality of life. PMID:15801260

    Poststroke patients with functional constipation, assessed by the Rome III criteria, from 6 hospitals were recruited in a study on the effects of the traditional Japanese medicine Daikenchuto (DKT) on constipation. Thirty-four patients (17 men and 17 women; mean age: 78.1 ± 11.6 years) were randomly assigned to 2 groups; all patients received conventional therapy for constipation, and patients in the DKT group received 15 g/day of DKT for 4 weeks. Constipation scoring system (CSS) points and the gas volume score (GVS) (the measure of the intestinal gas volume calculated from plain abdominal radiographs) were recorded before and after a 4-week observation period. The total score on the CSS improved significantly in the DKT group compared to the control (P < 0.01). In addition, scores for some CSS subcategories (frequency of bowel movements, feeling of incomplete evacuation, and need for enema/disimpaction) significantly improved in the DKT group (P < 0.01, P = 0.049, and P = 0.03, resp.). The GVS was also significantly reduced in the DKT group compared to the control (P = 0.03). DKT in addition to conventional therapy is effective in treating functional constipation in poststroke patients. This study was a randomized controlled trial and was registered in the UMIN Clinical Trial Registry (no. UMIN000007393). PMID:25089144

    A model dataset of patient profile information was created based on the items used at five Japanese university hospitals, the patient information data elements in Health Level 7 (HL7) v2.5, and the standard datasets for medical information exchange used in Japan. In order to check the validity of the model dataset, a cross-sectional survey was performed. A preliminary analysis of 20 Japanese hospitals found that most items were implemented at some hospitals, but the number of items implemented at many hospitals was rather small. This result strongly shows the necessity for a standardized dataset of patient profile information. PMID:27577415

    Listeria monocytogenes causes foodborne illnesses through consumption of ready-to-eat foods. Although 135-201annual listeriosis cases have been estimated in Japan, the details regarding the clinical isolates such as infection source, virulence level, and other genetic characteristics, are not known. In order to uncover the trends of listeriosis in Japan and use the knowledge for prevention measures to be taken, the genetic characteristics of the past human clinical isolates needs to be elucidated. For this purpose, multilocus tandem-repeat sequence analysis (MLTSA) and multi-virulence-locus sequence typing (MVLST) were used in this study. The clinical isolates showed a variety of genetically distant genotypes, indicating they were from sporadic cases. However, the MVLST profiles of 7 clinical isolates were identical to those of epidemic clone (EC) I isolates, which have caused several serious outbreaks in other countries, suggesting the possibility that they have strong virulence potential and originated from a single outbreak. Moreover, 6 Japanese food isolates shared their genotypes with ECI isolates, indicating that there may be risks for listeriosis outbreak in Japan. This is the first investigational study on genetic characteristics of Japanese listeriosis isolates. The listeriosis cases happened in the past are presumably sporadic, but it is still possible that some isolates with strong virulence potential have caused listeriosis outbreaks, and future listeriosis risks also exist.

    Antiplatelet therapy could prevent stent thrombosis, but may be associated with an increased risk of bleeding. Recent studies have revealed that bleeding complications are relatively frequent in patients with acute coronary syndromes. Our aim was to describe the current status of antiplatelet therapy for Japanese patients with acute myocardial infarction (AMI). The Japan AMI (J-AMI) registry is a prospective observational study that has enrolled 2,030 consecutive patients with stent thrombosis elevation myocardial infarction (STEMI) admitted to 213 participating Japanese institutions. Current antiplatelet therapy for STEMI was assessed, and the occurrence of bleeding complications (based on GUSTO bleeding criteria) and stent thrombosis was also evaluated. Additionally, the clinical course after bleeding episodes was investigated. Percutaneous coronary intervention (PCI) was done in 97.2% of the patients, using a drug-eluting stent in 30% and a bare metal stent in 63% of PCI cases. A 300-mg loading dose of clopidogrel followed by its administration at 75 mg/day with aspirin was the current standard treatment for Japanese STEMI patients. In-hospital bleeding complications occurred in 1.9%, especially in patients with severe clinical features or a history of cerebrovascular disease. Moderate to severe bleeding complications were associated with 10 deaths. The in-hospital stent thrombosis (ST) rate was 1.47 %, and loading with clopidogrel prior to PCI was significantly less frequent in patients who developed ST (P < 0.001). In conclusion, the J-AMI registry revealed that severe symptoms of STEMI increased the risk of bleeding, while delay of clopidogrel loading was associated with ST. These findings suggest the need for treatment based on risk stratification to improve the balance between the beneficial and adverse effects of antiplatelet therapy in Japanese STEMI patients.

    The changes in the quality of Japanese clinical trials were evaluated by comparing the results of Good Clinical Practice (GCP) audits conducted from April 1997 to March 2000 (fiscal year (FY) 1997-1999) with those from April 2001 to March 2002 (FY2001). During both of the periods inspections were undertaken by the Organization for Pharmaceutical Safety and Research (OPSR). The audit findings in the former period were based on the audits that covered 331 hospitals and 775 trials conducted under the old GCP guideline. The audits in the latter period targeted 147 hospitals and 238 trials conducted under the old or new GCP guideline. The total number of deficiencies detected by GCP audits in the former three-year period (FY 1997-1999) was 1529, and the corresponding number in the latter single year (FY 2001) was 912. Two remarkable changes in OPSR's findings were observed between FY 1997-1999 and FY 2001 as follows; the proportion of protocol deviations increased from 14.7% (225/1529) to 53.1% (484/912), while the proportion of errors in case report forms (CRFs) decreased from 43.6% (666/1529) to 15.4% (140/912). The new GCP guideline sets very high standards for a hospital's qualification: to have sufficient equipment and hospital resources, to have capacity for promptly responding to urgent trial-related problems, to have an IRB, and to have appropriate staff including clinical research coordinators (CRCs) assigned to the clinical trial. Our results suggest that the impact of the regulatory changes of applicable standard is large for a hospital's qualification for conducting clinical trials in Japan. PMID:16054582

    Examine the genotype-phenotype relationship in Japanese congenital central hypoventilation syndrome (CCHS) patients and estimate the incidence of CCHS in Japan. Subjects were 92 Japanese patients with PHOX2B mutations; 19 cases carried 25 polyalanine repeat expansion mutations (PARMs); 67 cases carried 26 or more PARMs; and 6 had non-PARMs (NPARMs). We collected clinical data in all patients and estimated the development or intelligent quotients only in the patients carrying 25 PARM. The estimated incidence of CCHS was greater than one case per 148 000 births. Polyhydramnios was observed in three cases. Twelve infants exhibited depressed respiration at birth. In 19 cases carrying 25 PARM, the male-to-female ratio was ~3, no cases had Hirschsprung disease; 7 cases (37%) developed hypoventilation after the neonatal period, and 8 cases (42%) had mental retardation. In other 73 cases carrying 26 or more PARMs or NPARMs, male-to-female ratio was equal; patients frequently complicated with Hirschsprung disease and constipation, and all patients presented with hypoventilation in the neonatal period. Clinical symptoms were severe in most patients carrying long PARMs and NPARMs. In 25 PARM, additional genetic and/or epigenetic factors were required for CCHS development and male sex is likely a predisposing factor. The patients carrying 25 PARM frequently had mental retardation likely because they were not able to receive appropriate ventilation support following a definitive diagnosis owing to subtle and or irregular hypoventilation. Molecular diagnosis provides a definitive diagnosis and enables to receive appropriate ventilator support. PMID:26063465

    To describe the reliability of Japanese clinical trials, we compared the results of a Good Clinical Practice (GCP) audit conducted between April 1997 and March 2000 (fiscal year (FY) 1997 - 1999) with those from April 2004 - March 2005 (FY2004). The number and proportion of various types of deficiencies described in GCP audit reports were compared between the 2 periods. The audit findings in the former period were based on official audits that covered 331 hospitals and 775 trials. The audits in the latter period targeted 114 hospitals and 189 trials. The inspection of former period was undertaken by the Organization for Pharmaceuticals Safety and Research (OPSR). On the other hand, the latter period was undertaken by the Pharmaceuticals and Medical Devices Agency (PMDA). The total number of deficiencies detected in GCP audits was 1,529 in the former 3-year period (FY1997 - 1999) and 819 in the latter period (FY2004). The total number of deficiencies detected and reported was more than 1.5-fold on an annual basis in the latter period. By category of deficiencies, the proportion of protocol deviations increased from 14.7 (225/1,529) to 45.7% (374/819), while the proportion of errors in case report forms (CRFs) decreased from 43.6 (666/ 1,529) to 27.1% (222/819). There were two remarkable changes in audit findings between FY1997 - 1999 and FY2004; the increase in the proportion of protocol deviations and the decrease in the proportion of CRF-related deficiencies. We think that in Japan the improvement of research environments is needed to provide reliable clinical data responsible for the regulatory standard of GCP. PMID:18793583

    HLA antigens in 104 Japanese patients and 41 families with myasthenia gravis (MG) were investigated. The frequencies of DR9 and DRw13 were significantly increased in the patients who developed MG before 3 yr of age. The DQw3 antigen was positive for all the patients that developed MG before 15 yr with only one exception. All the examined cases that developed MG before 3 yr (including this DQw3 negative patient) had the same DQA and DQB DNA restriction fragments. These HLA frequencies decreased as the age of onset increased, and no significant association was observed in adult-onset MG. No patients had B8, DR3, and DQw2. The relative risk was higher for the DR9/DRw13 heterozygotes (37.4) than for DR9 (16.4) or DRw13 (7.1) in the childhood-onset MG. Statistical analysis suggested that DR9 and DRw13 (or DQw1 and DQw3) act synergistically in the disease development. Family study revealed diverse DR9 haplotypes. The most frequent DRw13 haplotype was Bw44-BFF-C4A3B1-DRw13-DQw1, which may be evolutionarily related to the caucasian B8-DR3-DQw2 haplotype. These results showed that MG in early childhood in Japanese individuals is genetically different from that in adulthood and that in caucasians. Images PMID:1974553

    Peripheral myelin protein (PMP-22) gene aneuploidy results in Charcot-Marie-Tooth disease Type 1A (CMT1A) and the Hereditary Neuropathy with Liability to Pressure Palsy (HNPP) in Japanese patients as well as Caucasian Americans. Charcot-Marie-Tooth disease (CMT), the most common genetic neuropathy, results when expression of one of at least seven genes is defective. CMT1A, about half of all CMT mutations, is usually associated with a duplication spanning the peripheral myelin protein-22 gene on distal chromosome band 17p11.2. Autosomal dominant HNPP (hereditary pressure and sensory neuropathy, HPSN) results from a deletion of the CMT1A gene region. Multicolor in situ hybridization with PMP-22 gene region probe characterized HNPP deletion reliably and detected all different size duplications reported previously. In summary, 72% of 28 Japanese CMT1 (HMSNI) patients tested had the CMT1A duplication, while none of the CMT2 (HMSNII) or CMT3 (HMSNIII) patients had a duplication. Three cases of HNPP were identified by deletion of the CMT1A gene region on chromosome 17p. HNPP and CMT1A have been reported to result simultaneously from the same unequal recombination event. The lower frequency of HNPP compared to CMT1A suggests that HNPP patients have a lower reproductive fitness than CMT1A patients. This result, along with a CMT1A duplication found in an Asian Indian family, demonstrates the broad geographic distribution and high frequency of PMP-22 gene aneuploidy.

    The most problematic issue in clinical nephrology worldwide is the relentless and progressive increase in patients with end-stage renal disease (ESRD). Diabetic nephropathy has considerable impact on society in the areas of public health and social economy; many scientists are involved in research for the elucidation of the pathogenesis of diabetic nephropathy and for the prevention and cure of the disease. In contrast, diabetic nephropathy was a neglected or ignored disease in the historical era, and few dedicated physicians recognized the disease process of diabetic nephropathy. In this review, we look back on the history of basic and clinical research on diabetic nephropathy and survey the recent progress of the research, especially focusing on the contribution of Japanese scientists.

    Exome sequencing revealed a novel missense mutation (c.2152G>A, p.E713K) in the KIAA0196 gene in a Japanese patient with SPG8. To date, only 10 mutations in the KIAA0196 gene have been reported in the world. We describe the clinical and genetic findings in our patient with SPG8, which is a rare dominant hereditary spastic paraplegia. Notably, our patient showed mild upper limb ataxia, which is a relatively atypical symptom of SPG8. Thus, our patient showed a wide clinical spectrum of SPG8. PMID:26967522

    Between November, 1975 and November, 1981, 825 patients were treated with 30 MeV (d-Be) neutrons at the National Institute of Radiological Sciences, Chiba. At the Institute of Medical Science, Tokyo, 302 patients were referred to the Radiation Therapy department and were treated with 16 MeV (d-Be) neutrons. The emphasis of these clinical trials with fast neutrons was placed on the estimation of the effect of fast neutrons for locally advanced cancers or radioresistant cancers, and on evaluation of the rate of complication of normal tissues following irradiation with fast neutrons. Results were evaluated for patients with previously untreated cancer; local control of the tumor was observed in 59.1%. Complications requiring medical care developed in only 32 patients. Late reaction of soft tissue seemed to be more severe than that observed with photon beams. The results also suggest that for carcinoma of the larynx, esophagus, uterine cervix, Pancoast's tumor of the lung and osteosarcoma, fast neutrons were considered to be effectively applied in this randomized clinical trial. For carcinoma of the larynx, a fast neutron boost was effectively delivered, although an interstitial implant was necessarily combined with fast neutrons for carcinoma of the tongue. The cumulative survival rate of the patients with carcinoma of the esophagus treated with fast neutrons of 26% compared to the survival rate of 10.5% obtained using photons. The results also indicate that local control and relief of the symptom related to Pancoast's tumor of the lung seemed to be better with neutrons than with photons. For patients suffering from osteosarcoma, the surgical procedures preserving the function of the leg and arm were studied according to the better local control rate of the tumor following fast neutron beam therapy.

The cumulative survival rate of the patients with carcinoma of the esophagus treated with fast neutrons was 26% compared to the survival rate of 10.5% obtained using photons. This was supported by evidence from the pathological studies that showed that the tumor cells which had deeply invaded into the esophagus were effectively destroyed when fast neutrons were applied.

    Hereditary spastic paraplegia (HSP) is one of the most genetically heterogeneous neurodegenerative disorders characterized by progressive spasticity and pyramidal weakness of lower limbs. Because >30 causative genes have been identified, screening of multiple genes is required for establishing molecular diagnosis of individual patients with HSP. To elucidate molecular epidemiology of HSP in the Japanese population, we have conducted mutational analyses of 16 causative genes of HSP (L1CAM, PLP1, ATL1, SPAST, CYP7B1, NIPA1, SPG7, KIAA0196, KIF5A, HSPD1, BSCL2, SPG11, SPG20, SPG21, REEP1 and ZFYVE27) using resequencing microarrays, array-based comparative genomic hybridization and Sanger sequencing. The mutational analysis of 129 Japanese patients revealed 49 mutations in 46 patients, 32 of which were novel. Molecular diagnosis was accomplished for 67.3% (33/49) of autosomal dominant HSP patients. Even among sporadic HSP patients, mutations were identified in 11.1% (7/63) of them. The present study elucidated the molecular epidemiology of HSP in the Japanese population and further broadened the mutational and clinical spectra of HSP. PMID:24451228

    The nationwide surveillance on antimicrobial susceptibility of bacterial respiratory pathogens from patients in Japan, was conducted by Japanese Society of Chemotherapy, Japanese Association for Infectious Diseases and Japanese Society for Clinical Microbiology in 2010. The isolates were collected from clinical specimens obtained from well-diagnosed adult patients with respiratory tract infections during the period from January and April 2010 by three societies. Antimicrobial susceptibility testing was conducted at the central reference laboratory according to the method recommended by Clinical and Laboratory Standard Institutes using maximum 45 antibacterial agents. Susceptibility testing was evaluable with 954 strains (206 Staphylococcus aureus, 189 Streptococcus pneumoniae, 4 Streptococcus pyogenes, 182 Haemophilus influenzae, 74 Moraxella catarrhalis, 139 Klebsiella pneumoniae and 160 Pseudomonas aeruginosa). Ratio of methicillin-resistant S. aureus was as high as 50.5%, and those of penicillin-intermediate and -resistant S. pneumoniae were 1.1% and 0.0%, respectively. Among H. influenzae, 17.6% of them were found to be β-lactamase-non-producing ampicillin (ABPC)-intermediately resistant, 33.5% to be β-lactamase-non-producing ABPC-resistant and 11.0% to be β-lactamase-producing ABPC-resistant strains. Extended spectrum β-lactamase-producing K. pneumoniae and multi-drug resistant P. aeruginosa with metallo β-lactamase were 2.9% and 0.6%, respectively. Continuous national surveillance of antimicrobial susceptibility of respiratory pathogens is crucial in order to monitor changing patterns of susceptibility and to be able to update treatment recommendations on a regular basis.

    A unique factor, human T cell hypoglycaemic factor (hTCHF), has been shown to produce hypoglycaemia during the convalescent stage in the plasma of patients with Japanese encephalitis virus (JEV) infection. The present study was undertaken to investigate the ability of T cells from fresh peripheral blood mononuclear cells (PBMC) of such patients to produce hTCHF. The PBMC, as well as the individual subpopulations, were cultured for 24 h and the culture supernatants (CS) were assayed for hypoglycaemic activity. The activity was observed in the CD8+ T cells. The hypoglycaemia in JE-confirmed patients coincided with the gradual rise in circulating glucagon level, with no significant alterations in insulin, growth hormone and cortisol levels. The hTCHF was purified by ion exchange chromatography and the purified protein was observed as a approximately 25 kDa band on SDS-PAGE. Secretory hTCHF in the sera of patients and T cell CS was present in 88% of convalescent serum samples. We conclude that during the convalescent stage of JEV infection, a unique factor, hTCHF, is secreted by activated CD8+ T cells from patients and that this is responsible for the development of hypoglycaemia.

    Obesity is thought to be involved in the pathogenesis of psoriasis, although its impact on the therapeutic response to systemic treatments remains unclear. The aim of this study was to examine the association of body mass index (BMI) with the efficacy of ustekinumab in Japanese patients with psoriasis. Clinical data from a cohort of 111 Japanese patients treated with ustekinumab 45 mg between July 2011 and March 2014 were retrospectively evaluated. The measured outcome was improvement in the psoriasis area and severity index (PASI) score at week 16. Patients with BMI ≥ 25 and BMI < 25 had comparable rates of ≥50 and 75 % improvement in PASI (PASI-50 and PASI-75, respectively), whereas patients with BMI ≥ 25 had significantly lower PASI-90 and PASI-100 response rates. Patients with BMI ≥ 25 also showed significantly lower percent reduction in PASI than those with BMI < 25 at week 16 (85 vs. 74 %, P < 0.004). BMI was negatively correlated with percent reduction in PASI, whereas body weight was not. These results show that a higher BMI, but not body weight, is associated with lower effectiveness of ustekinumab for psoriasis. BMI ≥ 25 could therefore be a negative predictor of achieving PASI-90 and PASI-100 in patients with psoriasis when starting ustekinumab. PMID:25193345

    Background Patient-reported quality of life is strongly affected by some dermatologic conditions. We developed a Japanese version of the Dermatology Life Quality Index (DLQI-J) and used psychometric methods to examine its validity and reliability. Methods The Japanese version of the DLQI was created from the original (English) version, using a standard method. The DLQI-J was then completed by 197 people, to examine its validity and reliability. Some participants completed the DLQI-J a second time, 3 days later, to examine the reproducibility of their responses. In addition to the DLQI-J, the participants completed parts of the SF-36 and gave data on their demographic and clinical characteristics. Their physicians provided information on the location and clinical severity of the skin disease. Results The participants reported no difficulties in answering the DLQI-J items. Their mean age was 24.8 years, 77.2% were female, and 78.7% had acne vulgaris. The mean score of DLQI was 3.99(SD: 3.99). The responses were found to be reproducible and stable. Results of principal-component and factor analysis suggested that this scale measured one construct. The correlations of DLQI-J scores with sex or age were very poor, but those with SF-36 scores and with clinical severity were high. Conclusion The DLQI-J provides valid and reliable data despite having only a small number of items. PMID:16884543

    Pegvisomant is a GH receptor antagonist and strong inhibitor of insulin-like growth factor I (IGF-I) production. The treatment goal for acromegaly is to normalize serum IGF-I levels and attenuate associated symptoms. The efficacy and safety of pegvisomant as treatment for acromegaly have been reported in Caucasians, but not in Japanese. Here we report the clinical experience of using pegvisomant in Japanese patients with acromegaly. The efficacy and safety data for pegvisomant from two open-labeled clinical studies in Japan, conducted from 2004 to 2007, were re-analyzed using the new Japanese age- and sex-matched normative ranges for IGF-I. Eighteen patients with active acromegaly were enrolled in an initial pivotal study, and 16 of them were moved to a long-term (max 168 weeks) extension study. The dose of pegvisomant in the extension study was adjusted to 10-30 mg per day according to IGF-I levels. IGF-I normalization was observed in 81.3% (13/16 patients) during the extension study. The mean percentage decrease from baseline in serum IGF-I level was 64.7% at the time of last observation. The clinical symptoms and overall health status were improved, and the ring size was reduced over time until Week 12 and maintained. For safety, no clinically significant changes were observed both in the pituitary tumor size and the anti-GH antibody level. Three subjects were withdrawn from the studies due to an abnormal elevation of liver enzymes which resolved after discontinuation. Pegvisomant demonstrated excellent clinical efficacy and was well tolerated in Japanese patients with acromegaly. PMID:26796763

    Drug adherence is one of the important aspects in caring for patients with allergic rhinitis. To improve clinical efficacy of early treatment for Japanese cedar pollinosis (JCP), we evaluated the effect of drug adherence on patients' outcomes. Patients were randomly selected from 16 ENT clinical sites in Osaka and Wakayama between February 24 and March 8, 2003 (peak pollen season). Efficacy was assessed using patients' ratings of nasal and ocular symptoms and overall assessment in their condition compared with previous season ones. Costs include direct costs of the drugs used for treatment to JCP from January to February. Five hundred one patients taking early treatment were enrolled. Compared to low adherence patients, those who reported higher level of adherence significantly improved overall health condition, and achieved better symptom relief of rhinorrhea and nasal congestion. In multiple logistic regression analysis, the following factors were independent risk factors for low adherence: student (p=0.002), using OTC medications (p=0.006), and short-duration of medication (p=0.001). Low costs were also risk factor for low adherence. We conclude that taking medications for JCP for 22-28 days is the best way to enhance patients' outcomes. PMID:15492491

    Purpose This study investigated the relationships among the plasma levels of catecholamine metabolites, the clinical response to duloxetine treatment, and Val158Met polymorphism of the catechol-O-methyltransferase (COMT) gene. Subjects and methods Sixty-four patients and 30 healthy control subjects were recruited. Major depressive episodes were diagnosed using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria. The severity of depression was evaluated using the 17-item Hamilton Rating Scale for Depression (HAMD17). Patients whose HAMD17 scores were 15 or greater were enrolled in the study. Blood sampling and clinical evaluation were performed at week 0 and week 8. The levels of plasma catecholamine metabolites were measured using high-performance liquid chromatography with electrochemical detection. Genotyping was performed using direct sequencing. Results Thirty of 45 patients (67%) responded to duloxetine treatment during the 8 weeks of treatment. The baseline plasma levels of 3-methoxy-4-hydroxyphenylglycol (MHPG), but not homovanillic acid (HVA), were lower in patients with major depressive disorder (MDD) who had the Val/Val genotype than in patients who were Met-carriers. Patients with MDD and the Val/Val genotype, but not Met carriers, had increased plasma levels of MHPG after 8 weeks of duloxetine treatment. The baseline plasma MHPG levels in healthy control subjects with the Val/Val genotype were significantly higher than those in patients with MDD. Among the subjects in the MDD group with the Val/Val genotype, the plasma MHPG levels increased to the same degree as in the healthy control subjects with the Val/Val genotype after 8 weeks of duloxetine treatment. Conclusion The relationship among the COMT Val158Met polymorphism, plasma levels of catecholamine metabolites, and responses to duloxetine is complex. Nevertheless, our results suggest that patients with MDD and the

    Objectives Belimumab, an anti-B lymphocyte stimulator (BLyS) human monoclonal antibody, was approved in the United States, Canada and European Union for the treatment of the patients with systemic lupus erythematosus (SLE). However, belimumab had not been evaluated in Japanese patients. The objectives of this study were to evaluate the safety and tolerability of belimumab in Japanese patients with SLE, as well as to investigate the pharmacokinetics (PK) and biological activity of belimumab in this population. Methods A total of 12 Japanese patients were enrolled in a randomized, single-blind, placebo-controlled, dose-ascending design study. A dosing regimen of a single intravenous infusion over 1 hour of belimumab (1 mg/kg and 10 mg/kg) was employed. Patients were followed for 84 days after dosing to assess adverse events, pharmacokinetics, biomarkers and SLE disease activity. Clinical trial registration number ClinicalTrials.gov identifier is NCT01381536. Results Belimumab (1 mg/kg and 10 mg/kg) demonstrated a favorable clinical safety and tolerability profile in Japanese patients with SLE. The incidence of adverse events was similar among the two belimumab groups and placebo group. The PK profile of single-dose belimumab was approximately dose proportional, and the long terminal elimination half-life (12.4–15.7 days), low clearance (3.55–4.65 mL/day/kg), and small volume of distribution (76.2–80.1 mL/kg) were consistent with a fully humanized antibody. Effects of belimumab on B cells suggested biological activity effects expected as an inhibitor of BLyS. Limitation The small sample size and single dose design of this study prevent definitive conclusions regarding the safety, pharmacokinetics or pharmacodynamics of belimumab in a Japanese population being made. Conclusions The preliminary safety, PK profile, and observed biological activity of belimumab support further evaluation of its safety and efficacy in Japanese patient with SLE.

    Abstract Objective: To perform a postmarketing surveillance study evaluating the safety and effectiveness of abatacept in Japanese patients with rheumatoid arthritis (RA). Methods: Safety and effectiveness data were collected for all RA patients (at 772 sites) treated with intravenous abatacept between September 2010 and June 2011. Patients were treated by the approved dosing regimen according to the package insert. Treatment effectiveness was evaluated at baseline and at weeks 4, 12, and 24 using Disease Activity Score 28 (DAS28) according to erythrocyte sedimentation rate or serum C-reactive protein concentrations. Results: Overall, 3882 and 3016 abatacept-naïve RA patients were included in safety and effectiveness analyses, respectively. Adverse drug reactions (ADRs) were reported for 15.66% of patients and serious ADRs were detected for 2.52% of patients. The incidence of serious infections was 1.03% and these were mainly attributed to different types of bacterial pneumonia. Disease activity improved significantly over 6 months. Separate multivariate analysis identified predictors of severe ADR, and severe infections and factors predictive of clinically meaningful DAS28 improvement after 6 months of treatment with abatacept. Conclusions: Abatacept was efficacious and well tolerated in a clinical setting. No new safety concerns were detected. PMID:26635183

    Diagnosis of anti-BP180-type mucous membrane pemphigoid (BP180-MMP) is frustrated by the difficulty of detecting BP180 reactivity. A total of 721 patients with suspected MMP, selected from a cohort of 4,698 patients with autoimmune bullous disease (AIBD), were included in this study. Of these, 332 patients were tentatively diagnosed as BP180-MMP if they showed IgG/IgA reactivity with the epidermal side of 1M NaCl-split-skin and/or positive reactivity with BP180 in at least one of our antigen detection methods. Clinically, a predominance of female patients was found. Oral mucosal and cutaneous lesions were found in 85.5% and 41.0% of patients, respectively, and frequent treatments were systemic steroids, tetracycline/minocycline and diaminodiphenyl sulfone. Various immunological methods, including a newly developed BP180 C-terminal domain enzyme-linked immunosorbent assay (ELISA), revealed frequent reactivity with BP180 C-terminal and NC16a domains. Some patients reacted with BP180 and other antigens, indicating that BP180-MMP tends to concur with other AIBDs. This large study of patients with suspected BP180-MMP indicates the difficulty of diagnosis of BP180-MMP and the diagnostic usefulness of BP180 C-terminal domain ELISA. PMID:26984589

    For the first time, we performed an epidemiological study of SSc in Japan to study the factors influencing prognosis, survival rate and cause of death of Japanese SSc patients and to compare our data with those from foreign countries. Prognosis of 496 Japanese patients with progressive systemic sclerosis (SSc) was analyzed based on clinical data described in case cards provided by the members of the Scleroderma Research Committee of the Japanese Ministry of Health and Welfare. The essential observation period was from 5 to 20 years, at ending in 1994. Ninety patients died (males 11, females 79). The age of onset of the deceased patients was significantly higher than that of surviving patients (deceased, 45.6 yrs, surviving 41.3 yrs). Statistically significant factors for a poor prognosis were as follows: Barnett type III > type II > type I, positive for anti-Scl-70 antibody, negative for anti-centromere antibody. The survival rate at 5 years after the onset of the disease was 0.937, followed by 0.82 at 10 years, 0.567 at 20 years and 0.40 at 30 years after the onset. Sex was not a predictor for prognosis, although male patients died at an earlier stage of the disease. The most common causes of death were heart failure, pulmonary insufficiency, lung fibrosis, and renal failure. Twenty-four patients had cancer of which 13 were lung cancers. The current status of the survival rate and prognostic factors of 496 Japanese SSc patients is summarized. In future, more well-controlled studies using the same criteria should be performed for the better understanding and management of SSc. PMID:8973032

    Using whole exome sequencing data obtained from 1,685 Japanese cancer patients, we examined genetic variations of germline TP53 and found 10 types of non-synonymous single nucleotide variants. In the present study, we focused on 6 patients with germline D49H mutation located in the transactivation domain 2 of p53 protein, since the mutation seemed to be prevalent in cancer patients and to be pathogenic. According to the initial survey for family history of the proband with the germline TP53 D49H mutation, one osteosarcoma patient and his pedigree fulfill the criteria for Li-Fraumeni-like syndrome and the 2009 Chompret criteria for germline TP53 mutation screening. Since this patient possesses double germline mutations of TP53 D49H and A159D, further studies are required to evaluate contribution of the D49H mutation in this morbidity. The remaining 5 patients had family histories of cancer, but none fulfills the criteria either for the Li-Fraumeni/Li-Fraumeni-like syndromes or the 2009 Chompret criteria for germline TP53 mutation screening. It is possible to postulate that the germline TP53 D49H mutation is likely to be low-penetrant in some pedigrees. The present study also indicates that the survey for the germline TP53 mutation plays an important role in clinical practice as it will prevent mistaking cancer patients with unusual heredities for sporadic cases.

    Recurrent hot-spot mutations in the telomerase reverse transcriptase (TERT) promoter have been reported in various types of tumor. In several tumor types, TERT promoter mutations are associated with poor clinical outcomes. TERT promoter mutations are reported to be rare in soft tissue tumors, with the exception of myxoid liposarcoma (MLS). Our previous study reported that TERT promoter mutations occurred in a subset of solitary fibrous tumors (SFTs) and were associated with adverse clinical outcomes in Japanese individuals. The site-specific frequency (e.g. central nervous or soft tissue origin) of TERT promoter mutations in our SFT cases appeared to be different from previously reported values in a European population. These findings prompted the present study to elucidate the potential role of ethnic background in the different frequencies of TERT promoter mutations in bone and soft tissue sarcomas. In the present study, TERT promoter mutations were examined in 180 cases of bone and soft tissue sarcomas. TERT promoter region mutations were identified in 10 cases [5 SFTs, 3 MLSs, 1 undifferentiated pleomorphic sarcoma (UPS) and 1 malignant granular cell tumor]. All mutations were C228T. The frequencies of TERT promoter mutation in MLS and UPS were 23.1 (3/13) and 5% (1/20), respectively. Only 1/5 patients with TERT-mutated tumors experienced local recurrence or distant metastasis. The present study revealed the first case of a malignant granular cell tumor with a TERT promoter mutation and revealed that the frequency of TERT promoter mutations in MLSs of Japanese patients is lower compared with that reported in German patients, providing evidence of a possible ethnic difference in the frequency of TERT promoter mutations.

    The aim of this study was to investigate the pharmacokinetics, safety, and tolerability of voriconazole following intravenous-to-oral switch regimens used with immunocompromised Japanese pediatric subjects (age 2 to <15 years) at high risk for systemic fungal infection. Twenty-one patients received intravenous-to-oral switch regimens based on a recent population pharmacokinetic modeling; they were given 9 mg/kg of body weight followed by 8 mg/kg of intravenous (i.v.) voriconazole every 12 h (q12h), and 9 mg/kg (maximum, 350 mg) of oral voriconazole q12h (for patients age 2 to <12 or 12 to <15 years and <50 kg) or 6 mg/kg followed by 4 mg/kg of i.v. voriconazole q12h and 200 mg of oral voriconazole q12h (for patients age 12 to <15 years and ≥50 kg). The steady-state area under the curve over the 12-h dosing interval (AUC0-12,ss) was calculated using the noncompartmental method and compared with the predicted exposures in Western pediatric subjects based on the abovementioned modeling. The geometric mean (coefficient of variation) AUC0-12,ss values for the intravenous and oral regimens were 51.1 μg · h/ml (68%) and 45.8 μg·h/ml (90%), respectively; there was a high correlation between AUC0-12,ss and trough concentration. Although the average exposures were higher in the Japanese patients than those in the Western pediatric subjects, the overall voriconazole exposures were comparable between these two groups due to large interindividual variability. The exposures in the 2 cytochrome P450 2C19 poor metabolizers were among the highest. Voriconazole was well tolerated. The most common treatment-related adverse events were photophobia and abnormal hepatic function. These recommended doses derived from the modeling appear to be appropriate for Japanese pediatric patients, showing no additional safety risks compared to those with adult patients.

    Japanese encephalitis (JE) is the leading form of viral encephalitis in Asia. It is caused by the JE virus (JEV), which belongs to the family Flaviviridae. JEV is endemic to many parts of Asia, where periodic outbreaks take hundreds of lives. Despite the catastrophes it causes, JE has remained a tropical disease uncommon in the West. With rapid globalization and climatic shift, JEV has started to emerge in areas where the threat was previously unknown. Scientific evidence predicts that JEV will soon become a global pathogen and cause of worldwide pandemics. Although some research documents JEV pathogenesis and drug discovery, worldwide awareness of the need for extensive research to deal with JE is still lacking. This review focuses on the exigency of developing a worldwide effort to acknowledge the prime importance of performing an extensive study of this thus far neglected tropical viral disease. This review also outlines the pathogenesis, the scientific efforts channeled into develop a therapy, and the outlook for a possible future breakthrough addressing this killer disease. PMID:19787040

    Limited data exist on dementia in Native Hawaiians and many Asian subgroups in the United States. Inpatients with dementia have higher costs, longer stays, and higher mortality compared to those without dementia. This study compared the rates of inpatients with a dementia diagnosis for disaggregated Asian and Pacific Islanders (Native Hawaiian, Chinese, Japanese, Filipino) vs. White by age group (18-59, 60-69, 70-79, 80-89 and 90+ years) for all adult patients hospitalized in Hawai'i between December 2006 and December 2010. A total of 13,465 in patients with a dementia diagnosis were identified by ICD-9 codes. Rates were calculated using population size denominators derived from the US Census. Across all age categories, Native Hawaiians had the highest unadjusted rates of inpatients with dementia and were hospitalized with a dementia diagnosis at younger ages than other racial/ethnic groups. In adjusted models compared to Whites (controlling for gender, residence location, and insurer), Native Hawaiians had significantly higher rates of inpatients with dementia among those 18-59 years (aRR:1.50;95%CI:0.84-2.69), 60-69 years (aRR:2.53;95%CI:1.74-3.68), 70-79 years(aRR:2.19;95%CI:1.78-2.69) and 80-89 years (aRR:2.53;95%CI:1.24-1.71) as did Japanese aged 70-79 years (aRR:1.30;95%CI:1.01-1.67), 80-89 years (aRR:1.29;95%CI:1.05-1.57) and 90+ years (aRR:1.51;95%CI:1.24-1.85). Japanese aged 18-59 years had significantly lower rates than Whites (aRR:0.40; 95%CI:0.17-0.94).These patterns have important public health and clinical care implications for Native Hawaiians and older Japanese populations. Future studies should consider if preventable medical risk, care giving, socio-economic conditions, genetic disposition, or a combination of these factors are responsible for these findings.

    Objective Umeclidinium bromide (UMEC) 62.5 μg is a long-acting muscarinic antagonist (LAMA) that is administered once daily via inhalation for chronic obstructive pulmonary disease (COPD) treatment. The objective of this study was to evaluate the safety and tolerability of long-term treatment with UMEC 125 μg in Japanese patients with COPD. Methods This was a 52 week, multicenter, open-label study to evaluate the safety and tolerability of UMEC 125 μg once daily delivered via a novel dry powder inhaler (nDPI) in Japanese patients with COPD. The primary endpoint was the incidence and severity of all adverse events (AEs) throughout the 52 week treatment period. Clinical trial registration number ClinicalTrials.gov identifier is NCT01702363. Results A total of 153 patients were enrolled in the study. Of these, 131 patients started treatment with UMEC 125 μg, and 111 patients (85%) completed the study. AEs did not differ greatly in incidence over the various time periods (Weeks 0 to 12, 13 to 24, 25 to 36, and 37 to 52 of treatment) and did not increase with continued treatment. The incidence of drug-related AEs associated with the pharmacological effects of LAMAs (including constipation, blurred vision, and thirst) was low. Serious adverse events (SAEs) during the treatment period were reported in 17 patients (13%). SAEs reported in more than one patient were COPD exacerbation and pneumonia (3 patients each, 2%). One SAE of angina pectoris was considered to be drug related. No fatalities were reported during this study. Conclusions No new AEs were identified beyond those attributable to the pharmacological effects of LAMAs. UMEC 125 μg was well tolerated over 52 weeks of treatment in Japanese patients with COPD.

    Stereotactic body radiotherapy (SBRT) is a relatively new treatment for liver tumor. Outcomes of SBRT for liver tumors unsuitable for ablation or surgical resection were evaluated. A total of 79 patients treated with SBRT for primary hepatocellular carcinoma (HCC) between 2004 and 2012 in six Japanese institutions were studied retrospectively. Patients treated with SBRT preceded by trans-arterial chemoembolization were eligible. Their median age was 73 years, 76% were males, and their Child-Pugh scores were Grades A (85%) and B (11%) before SBRT. The median biologically effective dose (α/β = 10 Gy) was 96.3 Gy. The median follow-up time was 21.0 months for surviving patients. The 2-year overall survival (OS), progression-free survival (PFS), and distant metastasis-free survival were 53%, 40% and 76%, respectively. Sex and serum PIVKA-II values were significant predictive factors for OS. Hypovascular or hypervascular types of HCC, sex and clinical stage were significant predictive factors for PFS. The 2-year PFS was 66% in Stage I vs 18% in Stages II-III. Multivariate analysis indicated that clinical stage was the only significant predictive factor for PFS. No Grade 3 laboratory toxicities in the acute, sub-acute, and chronic phases were observed. PFS after SBRT for liver tumor was satisfactory, especially for Stage I HCC, even though these patients were unsuitable for resection and ablation. SBRT is safe and might be an alternative to resection and ablation. PMID:25691453

    Aim. The purpose of this retrospective study was to evaluate changes in clinical indicators which influence the quality of life (QOL) of patients with schizophrenia treated by antipsychotic therapy before and after switching to aripiprazole. Methods. A retrospective chart review of 27 patients diagnosed with schizophrenia and who were switched from one antipsychotic to aripiprazole was performed. Clinical indicators about the daily dosage of antipsychotics and antiparkinsonian drugs, psychiatric condition, and glucose/lipid metabolism, clinical evaluation by nursing observation were used to measure the responsiveness of subjects to aripiprazole. Results. Of the 27 subjects, 14 responded to the switch to aripiprazole with significant improvement of the Brief Psychiatric Rating Scale (BPRS) score (P = 0.04), significant decrease in dosage of antipsychotics in 71% of patients (P = 0.03), and tendency toward reduction in dosage of antiparkinsonian drugs (P = 0.07) and body mass index (BMI) (P = 0.06). However, 8 of 27 subjects had a significant increase in lipid levels after switching to aripiprazole (P = 0.01). Conclusion. QOL for subjects who responded to the switch to aripiprazole improved as indicated by lower doses of antipsychotic and antiparkinson medications, improvement in BPRS score, and a decrease in BMI. Results indicate little influence on patient's QOL. PMID:22970386

    Ozenoxacin, a novel non-fluorinated topical quinolone, was assessed for in vitro antimicrobial activity against clinical isolates of propionibacteria and staphylococci according to the broth microdilution method recommended by the Clinical and Laboratory Standards Institute. The isolates used in this study were collected from Japanese patients with acne vulgaris during a period from 2012 to 2013. The MIC90s of ozenoxacin against Propionibacterium acnes (n=266), Propionibacterium granulosum (n=10), Staphylococcus aureus (n=23), Staphylococcus epidermidis (n=229) and other coagulase-negative staphylococci (n=82) were ≤0.06, ≤0.06, ≤0.06, 0.125 and ≤0.06 µg ml-1, respectively. The antimicrobial activity of ozenoxacin against the clinical isolates of propionibacteria and staphylococci was greater than that of five reference antimicrobial agents which have been used for the treatment of acne vulgaris. The MICs of ozenoxacin were correlated with those of nadifloxacin in P. acnes and S. epidermidis isolates. However, the MICs of ozenoxacin were 0.25-0.5 µg ml-1 and 0.5-8 µg ml-1 against nadifloxacin-resistant P. acnes (MIC: ≥8 µg ml-1; n=8) and S. epidermidis (MIC: ≥64 µg ml-1; n=10), respectively. These results indicated the potent antimicrobial activity against P. acnes and S. epidermidis isolates resistant to nadifloxacin. Topical ozenoxacin could represent an alternative therapeutic drug for acne vulgaris based on its potent antimicrobial activity against the isolates of propionibacteria and staphylococci from acne patients.

    The efficacy of combined therapy with a retinoid and antibiotic for Japanese patients with acne vulgaris remains to be established. Further, maintenance strategies limiting the use of topical retinoids must be identified. The objectives of this study are to determine the efficacy of sequential application of topical adapalene and clindamycin phosphate and to assess the impact of this regimen on patients' quality of life. Sixty-six patients were recruited. The regimen comprised two phases. For the 4-week initial treatment, 1% clindamycin phosphate gel was applied twice daily and 0.1% adapalene gel, once. In the 4-week maintenance phase, patients were randomly assigned to the OD group (adapalene applied once daily) or the TW group (adapalene applied once daily on 2 days per week). The acne severity score, lesion counts, microcomedone count, and sebum amount were measured. Quality of life (QOL) was assessed using Skindex-16. All parameters improved significantly by week 4 of initial treatment. No statistically significant differences were found in the improvement of clinical findings between the groups. All QOL scores improved significantly and did not significantly differ between the groups. Our regimen may enable clinical control of acne in Japanese patients and improve their QOL. For limiting retinoid use, weekly application of adapalene during maintenance is suitable. PMID:21254867

    Introduction Co-infection of Japanese Encephalitis (JE) and Cysticercosis is attributed mainly to the common epidemiological features between the two diseases. Not much is known about the clinical implications of one infection over the other. Aim The study aimed at establishing whether JE-Cysticercosis co-infection is prevalent in the Upper Assam districts and to explore additional details about such co-infections both clinically and epidemiologically. Materials and Methods The present study was a retrospective cross-sectional hospital based study conducted between July 2013 and June 2014 and included 272 Acute Encephalitis Syndrome (AES) patients. Out of this, 137 JE positive and 135 non-JE Acute encephalitis patients were taken as cases and controls respectively. The diagnosis of JE and Cysticercosis was established by ELISA. Statistical Analysis EpiInfo ver. 7 was used for statistical analysis. Chi-square was used and p-value < 0.05 was considered to be statistically significant. Results The association of Cysticercosis with JE was found to be statistically significant (14.6%, p = 0.0019) in the cases with reference to the controls (3.7%). Moreover, the co-infections were found to be more common in case of adults (19.32%, p = 0.0360); with males having a greater odds (5.25, p = 0.0008) of harbouring the parasite as compared to females. Conclusion The study proves that the association of Cysticercosis and JE holds true in this region. PMID:27437215

    Elevated serum-soluble urokinase receptor (suPAR) levels have been described in patients with focal segmental glomerulosclerosis (FSGS) in several different cohorts. However, it remains unclear whether this is the case for Japanese patients and whether circulating suPAR can be clinically useful as a diagnostic marker. To determine this, we measured serum suPAR levels in 69 Japanese patients with biopsy-proven glomerular diseases in a cross-sectional manner. The serum suPAR levels showed a significant inverse correlation with renal function by univariate (R(2) of 0.242) and multivariate (β=0.226) analyses. Even after excluding patients with renal dysfunction, no significant difference in the suPAR levels was detected among the groups. Receiver operating characteristic analysis and measures of the diagnostic test performance showed that suPAR was not a useful parameter for differentiating FSGS from the other glomerular diseases (AUC-ROC: 0.621), although a small subgroup analysis showed that patients with FSGS, treated with steroids and/or immunosuppressants, had significantly lower suPAR levels. Patients with ANCA-associated glomerulonephritis had significantly higher levels of suPAR compared with the other disease groups, which may be owing to their lower renal function and systemic inflammation. Thus, suPAR levels are significantly affected by renal function and have little diagnostic value even in patients with normal renal function. PMID:24429394

    Fluvoxamine is a selective serotonin reuptake inhibitor widely used in the treatment of depression and other psychiatric diseases. The aim of this study was to assess the clinical impact of cigarette smoking on plasma fluvoxamine concentration in Japanese patients, and evaluate whether the cytochrome P450 (CYP) 1A2 and CYP2D6 genotypes have effects on that concentration. Thirty-two Japanese patients receiving fluvoxamine were enrolled. They were maintained on the same daily dose of fluvoxamine (mean + or - S.D., 109.4 + or - 66.2 mg/d) for at least 4 weeks to obtain the steady-state plasma concentration. The steady-state plasma concentration-to-dose (C/D) ratio of fluvoxamine in patients who smoked (n = 6, 11.8 + or - 6.5 ng/ml/dose) was significantly lower than that in non-smoker patients (n = 26, 22.8 + or - 11.2 ng/ml/dose). There was no significant difference for the C/D ratio of fluvoxamine in patients with CYP1A2 -3860G/G, -3860G/A, and -3860A/A between non-smokers and smokers. Among non-smoker patients, the C/D ratios of fluvoxamine in those with one and two mutated alleles of CYP2D6 were 1.6- and 1.4-fold higher, respectively, than those with no mutated alleles, though the differences among those three genotype groups were not significant. Furthermore, stepwise multiple regression analysis revealed that cigarette smoking and daily dose had significant positive correlations with the plasma concentration of fluvoxamine. Our findings suggest that cigarette smoking has a significant impact on the steady-state plasma concentration of fluvoxamine in Japanese patients. PMID:20118554

    Objectives: To examine anti-KIR4.1 antibodies by 2 different assays in Japanese patients with multiple sclerosis (MS) or neuromyelitis optica (NMO). Methods: One hundred sixty serum samples from 57 patients with MS, 40 patients with NMO/NMO spectrum disorder (NMOSD), and 50 healthy controls (all were Japanese) were tested with ELISA using a synthetic peptide of the first extracellular portion of human KIR4.1. In addition, we attempted to detect anti-KIR4.1 immunoglobulin G in the serum by the luciferase immunoprecipitation systems (LIPS) with the full length of human KIR4.1 produced in a human cell line, which is highly sensitive to single or multiple epitopes. Results: We failed to detect antibodies to the peptide fragment KIR4.183–120 in any case of MS and NMO/NMOSD using ELISA. Antibodies to the recombinant full length of KIR4.1 protein were detected in only 2 patients with MS and none in the patients with NMO/NMOSD by the LIPS assay. Conclusions: We developed 2 different methods (ELISA and LIPS) to measure autoantibodies to KIR4.1 in serum. We detected anti-KIR4.1 immunoglobulin G at a very low frequency in Japanese patients with MS or NMO/NMOSD. Serologic testing for human KIR4.1-specific antibodies is unlikely to improve the diagnosis of MS or NMO/NMOSD in Japanese patients. PMID:27489866

  12. HIV-associated Burkitt lymphoma in a Japanese patient with early submandibular swelling

    2013-01-01

    Background Patients infected with the human immunodeficiency virus (HIV) are at risk of developing malignancies and have an increased susceptibility to infection. HIV-associated Burkitt lymphoma (BL) is relatively rare in developed countries, but remains prevalent in developing counties and is sometimes compounded by the fact that patients may be unaware that they are HIV-positive. Case presentation A 37-year-old Japanese man was referred to our department for diagnosis and management of submandibular swelling. He was unaware that he was HIV-positive at the initial visit. Here, we describe our diagnostic approach, in which we used hematological and immunological investigations, biopsy, fluorescence-activated cell sorting and fluorescence in situ hybridization to confirm the diagnosis of HIV-associated BL. The patient has no risk factors for HIV infection, and the source of infection remains unclear. Conclusions In this case, submandibular swelling was the first clinical sign of pathology and the patient’s HIV-positive status only became evident later. It is highly likely that BL was triggered by HIV infection. PMID:24370065

    Although the empiric paradigm is now dominant in academic research, in Japan quite a few psychiatric clinicians still take phenomenological-anthropological approaches into consideration, especially when they address manic-depressive illness with typical endogenous features. This is because Shimoda's concept of “shuuchaku-kishitsu” (statothymia) has been widely accepted, together with other phenomenological views of continental origin. In the present paper the author first delineates Shimoda's concept which is based on observations of patients' personality features and the characteristics of their emotionality. He then attempts to refine this concept in spatiotemporal terms, presenting the view that in patients the past self tends to adhere to the present self (the term “shuuchaku” means “adhering to” or “preoccupied with”). He also considers that patients tend to incorporate “soto” (outer space) into “uchi” (inner space), where they believe that symbiotic relations are preserved. Finally, he argues the clinical significance of the presented views in the cultural milieu in which Japanese psychiatric practices are situated. PMID:21941642

    Recent results from the phase 3 ENESTnd (Evaluating Nilotinib Efficacy and Safety in Clinical Trials-Newly Diagnosed Patients) study have demonstrated superiority of nilotinib over imatinib for the treatment of newly diagnosed Philadelphia chromosome-positive chronic myeloid leukemia in the chronic phase (CML-CP). Here, we report results from the Japanese subset of patients in ENESTnd, and assess whether results in this subpopulation are consistent with the overall study population. Seventy-nine Japanese patients with CML-CP were randomized to receive nilotinib 300 mg twice daily (BID) (n = 30), nilotinib 400 mg BID (n = 24) or imatinib 400 mg once daily (QD) (n = 25). Major molecular response rates at 12 months, the primary endpoint, were at least twice as high for nilotinib 300 mg BID (57%) and nilotinib 400 mg BID (50%) compared with imatinib 400 mg QD (24%). No patient on nilotinib progressed, while one patient progressed on imatinib. Both drugs were generally well tolerated and discontinuations due to adverse events were comparable among treatment arms. The results in the subpopulation of Japanese patients from ENESTnd closely mirror the results of the overall population, and support the use of nilotinib at 300 mg BID in Japanese patients with newly diagnosed CML-CP.

    Several works have demonstrated the existence of a link between Mycobacterium avium subsp. paratuberculosis (MAP) and MS in Italy. In this study, we analyzed the serology of MAP in a Japanese population while looking at several markers of MAP. Fifty MS patients, 12 clinically isolated syndrome (CIS) patients, 30 other neurological disorders (OND) patients, and 50 healthy controls (HCs) were tested using ELISA for the presence of IgG antibodies toward immunodominant epitopes MAP_0106c121-132, homologues MBP85-98, homologues IRF5424-432, MAP_402718-32, and MAP_2694295-303. MAP-positive patients were also analyzed in relation to their clinical/demographic characteristics. Amongst all peptides, only antibodies against MAP_2694295-303 were more prevalent in MS patients (30%), as compared to OND patients (3%) (p = 0.009; area under roc curve (AUC) = 0.61) and HCs (2%) (p = 0.0004; AUC = 0.65) and in CIS patients (25%) compared to HCs (p = 0.023; AUC = 0.55). Logistic regression analysis showed a higher frequency of anti-MAP_2694295-303 antibodies in the sera of oligoclonal bands positive MS patients (p = 0.2; OR = 2, 95%CI: 0.55–7.7). These findings support the view that MAP could act as a risk factor or a triggering agent of MS in some Japanese patients with a genetic susceptibility to the mycobacterium. PMID:27356622

    Forty-seven Japanese patients with multiple sclerosis, 29 probable (clinically definite) and 18 possible, were studied by black-and-white checkerboard pattern reversal visual evoked potential and were compared with a control group of 20 healthy young adults. The major positive peak (P100) was found to be abnormal in 70% of all cases, 90% of probable cases and 39% of possible cases. P100 was delayed in 38% of all cases and was absent in 23% of all cases. None of the eyes showing a flat pattern response was in the acute stage of optic neuritis. The percentage of cases with no response (23% of all cases) was greater than any of the previously reported series from Western countries, substantiating the previously reported clinical features of oriental multiple sclerosis. The pattern response was absent only when testing eyes with severe visual impairment, whereas delayed latency of P100 was seen regardless of the severity of visual impairment, suggesting the usefulness of P100 latency for detecting subclinical optic nerve lesions.

    This phase 1, open-label, dose-escalation study investigated the tolerated dose (recommended dose), safety, efficacy, and pharmacokinetics of pomalidomide alone or pomalidomide plus low-dose dexamethasone in Japanese patients with refractory or relapsed and refractory multiple myeloma. Twelve patients were enrolled. Patients received pomalidomide 2 mg (Cohort 1) or 4 mg (Cohort 2) orally on day 1 and days 3-21 of a 28-day cycle. The tolerated dose of pomalidomide was determined to be 4 mg given on days 1-21 of a 28-day cycle. Efficacy outcomes with pomalidomide plus low-dose dexamethasone were consistent with those of previous studies. Responses (partial response or better) were achieved by three patients (25%; 1 [17%] in Cohort 1 and 2 [33%] in Cohort 2), and the median time to response was 6.4 months overall (9.0 months for Cohort 1 and 4.2 months for Cohort 2). The median progression-free survival was 5.5 months overall (5.1 months for Cohort 1 and not reached for Cohort 2). The most frequently occurring grade ≥3 adverse events were neutropenia (67%), anemia (25%), lymphopenia (25%), and pneumonia (25%), consistent with previous studies of pomalidomide plus low-dose dexamethasone in refractory or relapsed and refractory multiple myeloma. Further investigation of pomalidomide is recommended for Japanese patients with refractory or relapsed and refractory multiple myeloma.

    Interstitial lung disease (ILD) events have been reported in Japanese non-small-cell lung cancer (NSCLC) patients receiving EGFR tyrosine kinase inhibitors. We investigated proteomic biomarkers for mechanistic insights and improved prediction of ILD. Blood plasma was collected from 43 gefitinib-treated NSCLC patients developing acute ILD (confirmed by blinded diagnostic review) and 123 randomly selected controls in a nested case-control study within a pharmacoepidemiological cohort study in Japan. We generated ∼7 million tandem mass spectrometry (MS/MS) measurements with extensive quality control and validation, producing one of the largest proteomic lung cancer datasets to date, incorporating rigorous study design, phenotype definition, and evaluation of sample processing. After alignment, scaling, and measurement batch adjustment, we identified 41 peptide peaks representing 29 proteins best predicting ILD. Multivariate peptide, protein, and pathway modeling achieved ILD prediction comparable to previously identified clinical variables; combining the two provided some improvement. The acute phase response pathway was strongly represented (17 of 29 proteins, p = 1.0×10−25), suggesting a key role with potential utility as a marker for increased risk of acute ILD events. Validation by Western blotting showed correlation for identified proteins, confirming that robust results can be generated from an MS/MS platform implementing strict quality control. PMID:21799770

    Objectives To evaluate efficacy and safety of three different regimens of denosumab, a fully human monoclonal antibody to receptor activator of nuclear factor kappa B (RANK) ligand (RANKL), for Japanese patients with rheumatoid arthritis (RA). Methods In this multicentre, randomised, placebo-controlled phase II study, 350 Japanese patients with RA between 6 months and <5 years, stratified by glucocorticoid use and rheumatoid factor status, were randomly assigned to subcutaneous injections of placebo or denosumab 60 mg every 6 months (Q6M), every 3 months (Q3M) or every 2 months (Q2M). All patients basically continued methotrexate treatment and had a supplement of calcium and vitamin D throughout the study. The primary endpoint was change in the modified Sharp erosion score from baseline to 12 months. Results Denosumab significantly inhibited the progression of bone erosion at 12 months compared with the placebo, and the mean changes of the modified Sharp erosion score at 12 months from baseline were 0.99, 0.27 (compared with placebo, p=0.0082), 0.14 (p=0.0036) and 0.09 (p<0.0001) in the placebo, Q6M, Q3M and Q2M, respectively. Secondary endpoint analysis revealed that denosumab also significantly inhibited the increase of the modified total Sharp score compared with the placebo, with no obvious evidence of an effect on joint space narrowing for denosumab. As shown in previous studies, denosumab increased bone mineral density. No apparent difference was observed in the safety profiles of denosumab and placebo. Conclusions Addition of denosumab to methotrexate has potential as a new therapeutic option for patients with RA with risk factors of joint destruction. Trial registration number JapicCTI-101263.

    Oxcarbazepine is an anti-epileptic drug, which is almost completely metabolized by cytosolic enzymes in the liver to the active 10-monohyroxy metabolite (MHD) following oral administration. The pharmacokinetic (PK) profiles of MHD were evaluated in pediatric epileptic patients and a possible ethnic difference in PK of MHD between Japanese and non-Japanese pediatric patients was assessed. A non-linear mixed effect modeling approach was used to determine the PK of MHD. A one-compartment population model with first-order absorption appropriately described the PK of MHD. No clinically relevant differences were found for using body surface area or weight to explain between-patient variability, therefore the final model included the effects of body weight on apparent clearance (CL/F) and apparent volume of distribution (V/F) of MHD, and in addition, the effect of 3 concomitant anti-epileptic drugs (carbamazepine, phenobarbital and phenytoin) on CL/F of MHD. Inclusion of ethnicity as a covariate in the final model, concluded no ethnic difference with respect to CL/F of MHD between Japanese and non-Japanese patients. Hence, oxcarbazepine can be generally applied using the same dosage and administration for the treatment of partial onset seizures in pediatric patients, regardless of ethnicity. PMID:25989891

    This is first observational prospective study of insulin degludec in routine clinical practice that we evaluated the effect on glycemic control and risk of hypoglycemia in basal-bolus insulin therapy. We found that insulin degludec can maintain glycemic control at a lower insulin dose and frequency of hypoglycemia in type 1 diabetes, while it can improve glycemic control at equally insulin dose in type 2 diabetes. These results mean that insulin degludec is of use in routine clinical practice. PMID:26816606

    A 41-year-old man with hypertension and hyperlipidemia who complained of left hemiparesis after a temporal headache was admitted to our hospital. A cervical MRI with gadolinium enhancement revealed an intramural hematoma is compatible with right extracranial internal carotid artery dissection. Two weeks later, he complained of sudden onset of pain in the right side of his neck. The right extracranial internal carotid artery dissection followed by the right extracranial vertebral artery dissection was diagnosed. Spontaneous cervical artery dissection (SCAD) is one of the causes of stroke in young adults. The pathogenesis of SCAD remains unknown. Minor trauma like an excessive sneeze, migraine, and connective tissue disorders such as fibromuscular dysplasia and Ehlers-Danlos syndrome are well-known as risk factors for SCAD. Pathologically skin collagen abnormalities have been seen in German patients with SCAD without clinical evidence for any specific connective tissue disorder. We examined the ultrastructural morphology of the Japanese patient's dermal connective tissue components by electron microscopy. The patient's collagen fibers contained fibrils with highly variable diameters, and there were other ultrastructural abnormalities, including flower-like fibrils and large-diameter composite fibrils. This is the first report of a case of ultrastructural abnormalities of dermal connective tissue in a Japanese patient with SCAD. PMID:16619839

    AIM: To investigate the characteristics of gastric cancer and gastric mucosa in a Mongolian population by comparison with a Japanese population. METHODS: A total of 484 Mongolian patients with gastric cancer were enrolled to study gastric cancer characteristics in Mongolians. In addition, a total of 208 Mongolian and 3205 Japanese consecutive outpatients who underwent endoscopy, had abdominal complaints, no history of gastric operation or Helicobacter pylori eradication treatment, and no use of gastric secretion inhibitors such as histamine H2-receptor antagonists or proton pump inhibitors were enrolled. This study was conducted with the approval of the ethics committees of all hospitals. The triple-site biopsy method was used for the histologic diagnosis of gastritis and H. pylori infection in all Mongolian and Japanese cases. The infection rate of H. pylori and the status of gastric mucosa in H. pylori-infected patients were compared between Mongolian and Japanese subjects. Age (± 5 years), sex, and endoscopic diagnosis were matched between the two countries. RESULTS: Approximately 70% of Mongolian patients with gastric cancer were 50-79 years of age, and approximately half of the cancers were located in the upper part of the stomach. Histologically, 65.7% of early cancers exhibited differentiated adenocarcinoma, whereas 73.9% of advanced cancers displayed undifferentiated adenocarcinoma. The infection rate of H. pylori was higher in Mongolian than Japanese patients (75.9% vs 48.3%, P < 0.0001). When stratified by age, the prevalence was highest among young patients, and tended to decrease in patients aged 50 years or older. The anti-East-Asian CagA-specific antibody was negative in 99.4% of H. pylori-positive Mongolian patients. Chronic inflammation, neutrophil activity, glandular atrophy, and intestinal metaplasia scores were significantly lower in Mongolian compared to Japanese H. pylori-positive patients (P < 0.0001), with the exception of the intestinal

    Ultraviolet radiation is a risk factor for BRAF V600 mutations frequently found in melanomas that cause constitutive BRAF activation. Primary sites of melanoma and the frequency of BRAF mutations might differ between races. Melanoma is rare in Japan (1500–2000 cases/year compared with 132 000/year worldwide) and the frequency and distribution of BRAF V600 mutations are unknown. We aimed to investigate the frequency of BRAF V600 mutations in a cohort of Japanese patients with melanoma and determine the relationship between mutations and clinical/pathologic features. DNA was extracted from 80 formalin-fixed, paraffin-embedded tumours from individuals diagnosed with melanoma. BRAF V600 mutations were detected using the Cobas 4800 System with z480 Analyzer and Cobas 4800 BRAF V600 Mutation Test reagents. BRAF V600 mutations were detected in 41.8% of tested tumours, with an invalid rate of 1.3%. The mutation rate was more than 60% in patients aged less than 60 years and more than 36% in patients with stage III/IV disease. No sex difference in the mutation rate was observed. BRAF V600 mutations were detected in 18.8% of acral lentiginous melanomas (ALMs), 64.7% of superficial spreading melanomas, 50.0% of lentigo maligna melanomas and 20.0% of nodular melanomas. Although the mutation rate was low in ALMs, 36.4% were mutation positive at stage III/IV compared with 9.5% at stage I/II. This study confirmed associations among BRAF V600 mutations, pathological features and subtypes of melanoma. BRAF V600 mutations were more frequent in late-stage ALMs than in early-stage ALMs. Superficial spreading melanomas had similar mutation rates at all stages. These insights suggest improved treatment predictions for stage III/IV melanoma patients. PMID:25051202

    We have identified a new T-to-A single-base substitution at nucleotide 3548 (in the genomic sequence) in exon 6 in the glucocerebrosidase gene from a patient with Gaucher disease type 3. This mutation caused a substitution of isoleucine for phenylalanine at amino acid residue 213 (of 497 residues in the mature protein). By in vitro expression study in cultured mammalian cells, this mutation resulted in deficient activity of glucocerebrosidase. By allele-specific oligonucleotide hybridization of selectively PCR-amplified DNA from eight unrelated Japanese Gaucher disease patients, this mutant allele was observed in other neuronopathic Japanese Gaucher disease patients, in moderately frequent occurrence (three of six neuronopathic patients). This observation suggests that this allele was one of severe [corrected] alleles which were related to the development of neurological manifestations of Gaucher disease.

Although traditional microbiological research on periodontitis has focused on putative bacteria such as Porphyromonas gingivalis, the herpes virus is proposed to be involved in the pathogenesis of periodontitis because bacterial etiology alone does not adequately explain various clinical aspects. In this study, we established for the first time, more Epstein-Barr virus (EBV) DNA is found deeper in periodontal pockets of chronic periodontitis in Japanese patients. Subgingival samples were collected from 85 patients with chronic periodontitis having two periodontal sites with probing depths (PD) of ≤ 3 mm (shallow) or ≥ 5 mm (deep) and were subjected to a nested polymerase chain reaction. EBV DNA was more frequently detected in patients with deeper PD sites (66%) than in those with shallow PD sites (48%) or healthy controls (45%). Coexistence of EBV DNA and P. gingivalis was significantly higher in patients with deeper PD sites (40%) than in those with shallow PD sites (14%) or healthy controls (13%). Although no difference in clinical index for periodontitis, the odds ratio of EBV DNA in patients with deeper PD sites was 2.36, which was 2.07-fold higher than that in those with shallow PD sites. Interestingly, the odds of acquiring chronic periodontitis (PD ≥ 5 mm) were higher in the presence of both EBV DNA and P. gingivalis compared with either EBV DNA or P. gingivalis only. In addition, we also observed that EBV-encoded small RNA (EBER) in positive cells of human gingival tissues. These results would suggest that EBV DNA may serve as a pathogenic factor leading to chronic periodontitis among Japanese patients. PMID:23991022

    All plakin family proteins are known to be autoantigens in paraneoplastic pemphigus (PNP). In this study, we first examined whether PNP sera also react with epiplakin, another plakin protein, by various immunological methods using 48 Japanese PNP sera. Immunofluorescence confirmed that cultured keratinocytes expressed epiplakin. Epiplakin was detected by 72.9% of PNP sera by immunoprecipitation-immunoblotting with KU-8 cell extract, but not by immunoblotting of either normal human epidermal extract or KU-8 cell extract. Epiplakin was essentially not detected by 95 disease and normal control sera. Statistical analyses of various clinical and immunological findings revealed a significant correlation of the presence of anti-epiplakin antibodies with both bronchiolitis obliterans and mortality. No epiplakin-negative PNP case developed bronchiolitis obliterans. However, although 29.4% of European patients with PNP had bronchiolitis obliterans, significant correlation with anti-epiplakin autoantibodies was not observed. In further studies for lung, immunofluorescence showed the presence of epiplakin in normal human lung, particularly respiratory bronchiole, immunoprecipitation-immunoblotting showed that PNP sera reacted with epiplakin in cultured lung cells, and mice injected with polyclonal antibody specific to epiplakin histopathologically showed abnormal changes in small airway epithelia. These results indicated that epiplakin is one of the major PNP autoantigens and is related to PNP-related bronchiolitis obliterans. PMID:26802236

    We herein report a Japanese patient with megalencephalic leukoencephalopathy with subcortical cysts (MLC) who developed late-onset neuropsychological symptoms. He demonstrated characteristic clinical features of MLC during childhood, such as slowly progressive megalencepaly, motor impairment with ataxia and spasticity, mild mental retardation, and well-controlled epilepsy. Thereafter, he showed specific neuropsychological symptoms, such as motor and vocal tics, compulsive behavior, perseveration, acquired stuttering, and dystonia since the age of 12. His performance abilities had been unchanged but his verbal abilities had degraded during the past 14 years. Higher cortical dysfunction tests revealed a frontal lobe dysfunction. On repeated brain MRI, a leukoencephalopathy with subcortical cysts remained stationary from infancy. On single photon emission computed tomography (SPECT), a hypoperfusion in the frontal lobe was detected at the age of 3.5 and 17, but the severity of hypoperfusion was also unchanged, respectively. Our results indicate that the frontal lobe dysfunction may be relevant to the late-onset neuropsychological symptoms with MLC. PMID:17236107

    Globalization in Japan involves increases in the number of foreign residents. While there are some English-speaking Japanese doctors that are willing to see foreign patients, many are reluctant to do so. In this study, we attempted to clarify the factors that encourage Japanese doctors to see foreign patients. We conducted a questionnaire survey among medical doctors in Kobe City, Japan. The questionnaire was distributed to 172 doctors, and we received 139 responses. Statistical analysis showed a significant correlation between the frequency of seeing foreign patients and having the experience of studying abroad (p<0.05), confirming our hypothesis. There was also a significant correlation between having the experience of studying abroad and the doctors' self-evaluations of their English ability (p<0.05). There was no significant correlation found, however, between the frequency of seeing foreign patients and that of reading English research articles. These data suggested that the experience of living abroad rather than the exposure to English research articles was more highly correlated with seeing greater numbers of foreign patients. In conclusion, greater exposure to colloquial English was one of the determinants of the doctors' greater willingness to see foreign patients. In the Japanese medical education curriculum, therefore, it would be necessary to offer alternatives to studying abroad for those students who do not have such opportunities. PMID:23756658

    Objective: The aim of this study was to analyze the association between the variations of coenzyme Q2 4-hydroxybenzoate polyprenyltransferase gene (COQ2) and Japanese patients with multiple system atrophy (MSA). Methods: We investigated the genetic variations in exons 1, 2, 6, and 7 of the COQ2 gene in 133 Japanese patients with MSA and 200 controls and analyzed the association between the variations and MSA. Results: Six DNA variations (G21S, L25V, V66L, P157S, V393A, and X422K) were found in the 133 patients with MSA, and G21S and X422K were new variations that had never been reported. V66L was a common variation that was found in all 133 patients with MSA. G21S, P157S, V393A, and X422K did not show gene frequency differences between patients with MSA and controls. On the other hand, L25V was newly proven to be the only risk factor of sporadic MSA with predominant olivopontocerebellar ataxia. Conclusions: The present study suggests L25V variant of COQ2 gene as a genetic risk factor in Japanese patients with MSA with cerebellar ataxia. PMID:27123473

    Clinical features, such as obsessive-compulsive disorder (OCD) symptoms, were investigated in Japanese women with DSM-III-R eating disorders (EDs) and concurrent OCD in comparison to age-matched women with OCD. Sixteen women with restricting anorexia nervosa (AN), 16 with bulimia nervosa (BN), and 16 with both AN and BN (BAN) showed commonality in a more elevated prevalence of OCD symptoms of symmetry and order compared with 18 OCD women. Among the personality disorders (PDs), likewise, obsessive-compulsive PD (OCPD) was more prevalent in each ED group compared with the OCD group. However, aggressive obsessions were more common in both BN and BAN subjects compared with AN subjects. Subjects with bulimic symptoms were also distinguished from AN subjects by impulsive features in behavior and personality. Thus, an elevated prevalence of aggressive obsessions along with an admixture of impulsive and compulsive features specifically characterized the clinical features of bulimic subjects with OCD.

    Background Traditional Japanese Medicine (Kampo) is often used in Japan, but very little data on its users are available. We investigated who uses Kampo, the reasons and opinions for its use. Methods Questionnaire survey in three Japanese outpatient clinics offering Kampo in different settings: Kampo only, Kampo and traditional Chinese medicine, Kampo and Western medicine. Before seeing the doctor, patients were asked about socio-demographic data, medical history, experience with Kampo, general health-related opinions and behaviours, opinions about Western medicine and Kampo, and reasons for Kampo utilization. Descriptive statistics and predictors for Kampo use were calculated. Results A total of 354 questionnaires were completed. Participants were 50.97 ± 15.60 (mean ± SD) years of age, 68% were female. Of all patients, 73% (n = 202) were using Kampo currently and 84% (297) had taken Kampo before. Questions on general health-related opinions and behaviour revealed a strong environmental awareness. The most frequent indications for earlier Kampo use were: common cold (36%), gastrointestinal complaints (30%), oversensitivity to cold (“Hi’e-sho”; 29%), stress/anxiety (21%), and shoulder stiffness (20%). Kampo users suffered more often from chronic illnesses (OR 2.88 [1.48-5.58]). Beliefs in underlying philosophy (Wu Xing (adjusted OR 3.08, [1.11-8.55]), Ying and Yang (OR 2.57 [1.15-5.73], a holistic way of seeing the patient (OR 2.17 [1.53-3.08]), and in Kampo efficacy (OR 2.62 [1.66-4.13]) were positively associated with Kampo use. So was, interestingly, conviction of the efficacy of Western medicine (OR 1.87 [1.28-2.74]). Half of the patients had a general preference for a combination of Kampo and Western treatment. Conclusions Most patients visiting a clinic that also provided Kampo had previous experience with Kampo. Usage was associated with beliefs in philosophical Kampo concepts and its efficacy.

    The etiology of idiopathic short stature (ISS) and Leri-Weill dyschondrosteosis (LWD) in European patients is known to include SHOX mutations and copy-number variations (CNVs) involving SHOX and/or the highly evolutionarily conserved non-coding DNA elements (CNEs) flanking the gene. However, the frequency and types of SHOX abnormalities in non-European patients and the clinical importance of mutations in the CNEs remains to be clarified. Here, we performed systematic molecular analyses of SHOX for 328 Japanese patients with ISS or LWD. SHOX abnormalities accounted for 3.8% of ISS and 50% of LWD cases. CNVs around SHOX were identified in 16 cases, although the ~47 kb deletion frequently reported in European patients was absent in our cases. Probably damaging mutations and benign/silent substitutions were detected in four cases, respectively. Although CNE-linked substitutions were detected in 15 cases, most of them affected poorly conserved nucleotides and were shared by unaffected individuals. These results suggest that the frequency and mutation spectrum of SHOX abnormalities are comparable between Asian and European patients, with the exception of a European-specific downstream deletion. Furthermore, this study highlights the clinical importance and genetic heterogeneity of the SHOX-flanking CNVs, and indicates a limited clinical significance of point mutations in the CNEs.

    The Japanese health care system has been highly praised for its universal access, freedom of patient choice, maintenance of a private system, and creative funding. Japanese citizens enjoy general good health, low infant mortality, and long life expectancy. Nevertheless, aspects of Japanese medical education, both graduate and undergraduate, and the structure of academic departments differ from those seen in the United States. A sabbatical spent teaching general internal medicine in Japan provided the experience for this review of the Japanese system. I describe the structure and function of departments of medicine and observations made at daily clinical teaching exercises in hospitals throughout the country. PMID:8160464

    Previous studies consistently reported a link between bulimic behaviors and high Novelty Seeking (NS), as measured by the Temperament and Character Inventory (TCI). However, it remains unclear whether this relationship is universal and occurs in different environments. Subjects of the present study consisted of 66 patients with anorexia nervosa restricting type (AN-R), 59 patients with anorexia nervosa binge eating/ purging type (AN-BP), 101 patients with bulimia nervosa purging type (BN), and 75 controls. NS score in AN-R patients was significantly lower than that in controls, although NS in BN patients did not differ from that in controls. The temperament of AN-R patients seems to be universal, even in different environments. Conversely, something other than temperament might be important in the development of bulimia nervosa in Japan.

    Background Previous work suggests that Japanese patients with type 2 diabetes mellitus (T2DM) may respond more favorably to a DPP-4 (dipeptidyl peptidase-4) inhibitor than Caucasians. We aimed to compare the efficacy of the DPP-4 inhibitor vildagliptin (50 mg twice daily [bid]) between Japanese and Caucasian populations. Methods This analysis pooled data from 19 studies of drug-naïve patients with T2DM who were treated for 12 weeks with vildagliptin 50 mg bid as monotherapy. The pool comprised Japanese patients (n=338) who had been treated in Japan and Caucasian patients (n=1,275) who were treated elsewhere. Change from baseline (Δ) in glycated hemoglobin (HbA1c) at 12 weeks (in millimoles per mole) versus baseline HbA1c (both in percentage National Glycohemoglobin Standardization Program units [NGSP%] and millimoles per mole) for each population was reported. Universal HbA1c in millimoles per mole was calculated from either the Japanese Diabetes Society or the NGSP% HbA1c standards. Results At baseline, mean values for Japanese and Caucasian patients, respectively, were as follows: age, 59 years and 56 years; % male, 69% and 57%. The average HbA1c was reduced from 7.90% to 6.96% (Japanese Diabetes Society) and from 8.57% to 7.50% (United States National Glycohemoglobin Standardization Program), while HbA1c was reduced from 63 mmol/mol to 53 mmol/mol and from 70 mmol/mol to 58 mmol/mol in Japanese and Caucasians, respectively. ΔHbA1c increased with increasing baseline in both populations. The slopes were the same (0.41, r2=0.36; and 0.41, r2=0.15), and the intercepts were 15.4 mmol/mol and 17.2 mmol/mol, respectively. In Japanese patients, mean ΔHbA1c was greater by 1.7 mmol/mol (0.2% NGSP HbA1c) at any given baseline HbA1c than in Caucasians (P=0.01). Conclusion The present pooled analysis suggests that Japanese patients respond better to vildagliptin treatment compared with Caucasians. However, when glycemic control was corrected by using the same glycemic

    Background A founder variant of RNF213, p.R4810K (c.14429G>A, rs112735431), was recently identified as a major genetic risk factor for moyamoya disease (MMD) in Japan. Although the association of p.R4810K was reported to be highly significant and reproducible, the disease susceptibility of other RNF213 variants remains largely unknown. In the present study, we systematically evaluated the coding variants detected in Japanese patients and controls for associations with MMD. Methods and Results To detect variants of RNF213, all coding exons were sequenced in 27 Japanese MMD patients without p.R4810K. We also validated all previously reported variants in our case–control samples and tested for associations in combination with previous Japanese study cohorts, including the 1000 Genomes Project data set, as population-based controls. Forty-six missense variants other than p.R4810K were identified among 370 combined patients and 279 combined controls in Japan. Sixteen of 46 variants were polymorphisms with minor allele frequency >1%, and, after conditioning on the p.R4810K genotype, were not associated with MMD. We conducted a variable threshold test using Combined Annotation-Dependent Depletion on the remaining 30 rare variants (minor allele frequency <1%), and the results showed that the frequency of potentially functional variants was significantly higher in patients than in controls (permutation, minimum P=0.045). Conclusions Not only p.4810K but also other functional missense variants of RNF213 conferred susceptibility to MMD. Our analysis also revealed that ≈20% of Japanese MMD patients did not harbor susceptibility variants of RNF213, indicating the presence of other susceptibility genes for MMD. PMID:25964206

    Xq28 duplication syndrome including MECP2 is a neurodevelopmental disorder characterized by axial hypotonia at infancy, severe intellectual disability, developmental delay, mild characteristic facial appearance, epilepsy, regression, and recurrent infections in males. We identified a Japanese family of Xq28 duplications, in which the patients presented with cerebellar ataxia, severe constipation, and small feet, in addition to the common clinical features. The 488-kb duplication spanned from L1CAM to EMD and contained 17 genes, two pseudo genes, and three microRNA-coding genes. FISH and nucleotide sequence analyses demonstrated that the duplication was tandem and in a forward orientation, and the duplication breakpoints were located in AluSc at the EMD side, with a 32-bp deletion, and LTR50 at the L1CAM side, with "tc" and "gc" microhomologies at the duplication breakpoints, respectively. The duplicated segment was completely segregated from the grandmother to the patients. These results suggest that the duplication was generated by fork-stalling and template-switching at the AluSc and LTR50 sites. This is the first report to determine the size and nucleotide sequences of the duplicated segments at Xq28 of three generations of a family and provides the genotype-phenotype correlation of the patients harboring the specific duplicated segment.

    Purpose To report a rare case of idiopathic intracranial hypertension (IIH) in a prepubertal pediatric patient. Case Report The patient was an 11-year-old Japanese boy. Initially, an ophthalmologist found severe papilledema, and the patient was diagnosed with IIH. He was unresponsive to conservative therapy, and a ventriculoperitoneal shunt was inserted in the Neurosurgery Department because the visual impairment was severe. Twelve months after the shunt, the improvement in vision was limited due to optic disc atrophy. Conclusion Ophthalmologists need to be more aware of II, especially in cases with severe papilledema that can lead to permanent reduction of vision. PMID:27065853

    Conclusion Cochlear implantation (CI) for Japanese single-sided deafness patients resulted in improved speech perception, increased sound localization accuracy, and reduced tinnitus handicap. Objectives This study reports results for five adult SSD cases with CI, focusing on the benefits they obtained in terms of speech recognition, sound localization, and tinnitus handicap. Methods Five Japanese patients meeting the eligibility criteria were included in this study. All patients were implanted with a fully inserted MED-EL Concerto FLEX28® implant (MED-EL, Innsbruck, Austria). Speech perception outcomes in noise, as well as sound localization and tinnitus disturbance, were assessed pre-surgically and at 1, 3, 6, and 12 months after CI activation. Results The Japanese monosyllable test score in noise improved gradually after implantation. In some cases, speech perception ability appeared unstable, particularly in the first 1-6 months after implantation. The sound localization ability showed marked improvement in all cases, with the disturbance to daily life caused by tinnitus also decreasing in all cases from the early post-operative period.

    Objectives The genotype-phenotype correlation of MEFV remains unclear for the familial Mediterranean fever (FMF) patients, especially without canonical MEFV mutations in exon 10. The risk of FMF appeared to be under the influence of other factors in this case. The contribution of HLA polymorphisms to the risk of FMF was examined as strong candidates of modifier genes. Methods Genotypes of HLA-B and -DRB1 loci were determined for 258 mutually unrelated Japanese FMF patients, who satisfied modified Tel-Hashomer criteria, and 299 healthy controls. The effects of carrier status were evaluated for the risk of FMF by odds ratio (OR). The HLA effects were also assessed for clinical forms of FMF, subsets of FMF with certain MEFV genotypes and responsiveness to colchicine treatment. Results The carriers of B*39:01 were increased in the patients (OR = 3.25, p = 0.0012), whereas those of DRB1*15:02 were decreased (OR = 0.45, p = 0.00050), satisfying Bonferroni’s correction for multiple statistical tests (n = 28, p<0.00179). The protective effect of DRB1*15:02 was completely disappeared in the co-existence of B*40:01. The HLA effects were generally augmented in the patients without a canonical MEFV variant allele M694I, in accordance with the notion that the lower penetrance of the mutations is owing to the larger contribution of modifier genes in the pathogenesis, with a few exceptions. Further, 42.9% of 14 colchicine-resistant patients and 13.5% of 156 colchicine-responders possessed B*35:01 allele, giving OR of 4.82 (p = 0.0041). Conclusions The differential effects of HLA class I and class II polymorphisms were identified for Japanese FMF even in those with high-penetrance MEFV mutations. PMID:25974247

    The mouse obese (ob) gene has recently been isolated through the positional cloning technique and has been proved to result in the obese and NIDDM phenotype in mice when mutated (Nature 372:425-432, 1994). More recently, it has been demonstrated, by experiments with recombinant ob protein, that ob gene product can cause mice, including ob/ob mice, diet-induced obesity mice, and normal mice, to lower their food intake and body weight (Science 269:540-549, 1995). To investigate the genetic and/or environmental influences underlying the development of NIDDM associated with obesity, we isolated and partially sequenced the human obese (OB) gene. The human OB gene isolated in this study encoded 167 amino acids and its open reading frame was revealed to be divided into two parts with an intermediate intron of approximately 2.4 kb. Using the single-strand conformation polymorphism (SSCP) technique, we screened Japanese and Asian Indian subjects for mutations in the protein coding regions of the OB gene. A total of 75 NIDDM patients with obesity (54 Japanese and 21 Asian Indians), 40 NIDDM patients without obesity (34 Japanese and 6 Asian Indians), and 34 Japanese patients with simple obesity showed no abnormal SSCP patterns in either component of the coding sequences. These results suggested that mutations in the coding regions of the OB gene are not likely to be commonly identifiable and that there would likely be a kind of obesity-associated NIDDM not caused by mutations of the OB gene.

    The antifungal agents approved in Japan for pediatric use are limited and many unapproved drugs are actually used without clear instruction for dosage. We investigated the pharmacokinetics of caspofungin for the treatment of invasive candidiasis and invasive aspergillosis in 20 Japanese pediatric patients using a pediatric-specific dosage based on body surface area. Caspofungin was administered intravenously over 60 min as 70 mg/m(2) on Day 1, followed by 50 mg/m(2) per day. Five or 4 point blood sampling were done in 15 patients on Day 4-5 to calculate AUC0-24 h. The geometric means (95% confidence interval) of C24 h and AUC0-24 h in the pediatric patients were 3.3(2.5, 4.4) μg/mL and 175.1 (139.3, 220.1) μg hr/mL, respectively, which were comparable to those in Japanese adult patients [3.2 (2.8, 3.5) μg/mL and 144.9 (131.7, 159.3) μg hr/mL, respectively]. Among the 20 patients, 10 (50%) had at least 1 drug-related adverse event which was considered related to caspofungin therapy. No drug-related serious adverse event and no death occurred. The most common drug-related adverse events were events relating to hepatic function (mainly increases in ALT and AST). The overall success in efficacy was observed in 13 of 20 patients. In conclusion, once daily administration of caspofungin (70 mg/m(2) on Day 1, followed by 50 mg/m(2) [maximum daily dose not to exceed 70 mg]), which is the same dosage being used in overseas, achieved sufficient drug exposure and a favorable efficacy and acceptable safety profile in Japanese pediatric patients with invasive fungal infections.

    Tetracyclines are administered to cure Japanese spotted fever (JSF) and tsutsugamushi disease (TD). It is generally said that the clinical course of JSF is worse than that of TD despite antibiotic treatment. The precise mechanism underlying the more severe clinical course of JSF is not fully understood. We therefore examined whether the differential cytokine profile between these two infectious diseases contributes to the difference in clinical severity. The serum concentrations of various cytokines (tumor necrosis factor alpha [TNF-α], interleukin-6 [IL-6], and gamma interferon [IFN-γ]) and chemokines (IL-8, interferon-inducible protein 10 [IP-10], monocyte chemoattractant protein 1 [MCP-1], macrophage inflammatory protein 1α [MIP-1α], MIP-1β, and eotaxin) were measured in 32 TD and 21 JSF patients. The results showed that serum levels of TNF-α in the acute phases of TD and JSF were significantly increased, with a higher concentration of TNF-α in patients with JSF (mean, 39.9 pg/ml) than in those with TD (mean, 13.8 pg/ml). Comparatively higher levels of other cytokines and chemokines (IL-6, IFN-γ, IL-8, IP-10, MCP-1, MIP-1α, and MIP-1β) were also observed in the acute phase of JSF. The clinical severity score (3.67 ± 1.71) of JSF patients was higher than that of TD patients (1.47 ± 0.77). Our findings revealed that the cytokine and chemokine levels in the acute phase of JSF were significantly higher than those in the acute phase of TD. The differential cytokine levels may be related to the difference in clinical severity between JSF and TD. PMID:24671792

    Objectives This study evaluated the feasibility of cognitive behavioral therapy (CBT) for Japanese Parkinson’s disease (PD) patients with depression. To increase cultural acceptability, we developed the CBT program using manga, a type of Japanese comic novel. Methods Participants included 19 non-demented PD patients who had depressive symptoms (GRID-Hamilton Rating Scale for Depression score ≥8). A CBT program comprising six sessions was individually administered. We evaluated the feasibility and safety of the CBT program in terms of the dropout rate and occurrence of adverse events. The primary outcome was depressive symptom reduction in the GRID-Hamilton Rating Scale for Depression upon completion of CBT. Secondary outcomes included changes in the self-report measures of depression (Beck Depression Inventory-II, Hospital Anxiety and Depression Scale-Depression), anxiety (Hospital Anxiety and Depression Scale-Anxiety, State and Trait Anxiety Inventory, Overall Anxiety Severity and Impairment Scale), functional impairment, and quality of life (Medical Outcomes Study 36-Item Short-Form Health Survey). Results Of the 19 participants (mean age =63.8 years, standard deviation [SD] =9.9 years; mean Hohen–Yahr score =1.7, SD =0.8), one patient (5%) withdrew. No severe adverse event was observed. The patients reported significant improvements in depression (Hedges’ g =−1.02, 95% confidence interval =−1.62 to −0.39). The effects were maintained over a 3-month follow-up period. Most of the secondary outcome measurements showed a small-to-moderate but nonsignificant effect size from baseline to post-intervention. Conclusion This study provides preliminary evidence that CBT is feasible among Japanese PD patients with depression. Similar approaches may be effective for people with PD from other cultural backgrounds. The results warrant replication in a randomized controlled trial. PMID:27354802

    The Japanese traditional herbal medicine, Kampo, has gradually reemerged and 148 different formulations (mainly herbal extracts) can be prescribed within the national health insurance system. The objective of this article is to introduce Kampo and to present information from previous clinical studies that tested Kampo formulae. In addition, suggestions on the design of future research will be stated. The literature search was based on a summary, up until January 2009, by the Japanese Society of Oriental Medicine and included only those trials which were also available in either Pubmed or ICHUSHI (Japan Medical Abstracts Society). We included 135 studies, half of these studies (n = 68) used a standard control and 28 a placebo control. Thirty-seven trials were published in English [all randomized controlled trials (RCTs)] and the remaining articles were in Japanese only. The sample size for most studies was small (two-third of the studies included less than 100 patients) and the overall methodological quality appeared to be low. None of the studies used Kampo diagnosis as the basis for the treatment. In order to evaluate Kampo as a whole treatment system, certain aspects should be taken into account while designing studies. RCTs are the appropriate study design to test efficacy or effectiveness; however, within the trial the treatment could be individualized according to the Kampo diagnosis. Kampo is a complex and individualized treatment with a long tradition, and it would be appropriate for further research on Kampo medicine to take this into account. PMID:21687585

    Sleep disorder and poor sleep quality are common in chronic hemodialysis (HD) patients. They have been claimed as a cause of morbidity and mortality. The relationship between the degree of sleepiness and survival has not been studied. We studied the degree of sleepiness in 1,252 adult HD patients (age ≥20 years) recruited into the Dialysis Outcomes Practice Pattern Study in Japan (J-DOPPS III), using the Japanese version of the Epworth Sleepiness Scale (JESS) questionnaire. Demographic data were presented for three subgroups: low, intermediate, and high JESS score. Cox proportional hazard regression analysis was performed to estimate the independent effect of several variables on survival. The hazard ratio for mortality was 2.312 (95% CI 1.267-4.220; p = 0.006) for those with a high JESS score (vs. those with a low JESS score) after adjusting for age, vintage (length of time on HD), sex, diabetes, body mass index, cardiovascular disease, HD treatment regimen (time, frequency, and single-pool Kt/V), laboratory data (serum albumin, creatinine, and total cholesterol), and medication (antihypertensive drugs, erythropoietin, vitamin D, and phosphate binders). Patients ≥70 years of age with comorbid conditions (congestive heart failure, stroke, and diabetes) showed a significantly higher JESS score (≥16). The JESS score did not show interaction by age. Results showed that the degree of sleepiness is related to survival in Japanese HD patients, particularly in elderly patients. PMID:25572670

    The aim of the present study was to clarify the therapeutic range and adequate dose of sunitinib in Japanese renal cell carcinoma patients by means of a pharmacokinetic-pharmacodynamic analysis of sunitinib-induced thrombocytopenia. Six patients with renal cell carcinoma were enrolled in this study. After starting the sunitinib treatment, between three and seven blood samples were obtained from each patient just before the administration of sunitinib. Serum concentrations of sunitinib and its active metabolite N-desethyl-sunitinib were fit to the 1-compartment model with first-order absorption. Changes in platelet counts were fit to the pharmacokinetic-pharmacodynamic model, in which the proliferation of platelet progenitor cells was assumed to be linearly inhibited by sunitinib and its metabolite. All patients using 50 mg as an initial dose of sunitinib developed grade 2 or 3 thrombocytopenia. The pharmacokinetic-pharmacodynamic model created successfully described the time course of sunitinib-induced thrombocytopenia and could predict changes in platelet counts after alterations to the dosage of sunitinib administered. The simulation results indicated that the total trough level of sunitinib to avoid severe thrombocytopenia should be <100 ng/mL, and also that the initial daily dose of sunitinib could be reduced to 37.5 mg or 25 mg in most Japanese patients. In addition to the pharmacokinetic-guided dosage adjustment, the careful monitoring of platelet counts is required for the safe use of sunitinib. PMID:25757921

    Immunodeficiency, centromeric instability and facial anomalies (ICF) syndrome is a rare autosomal recessive disorder that shows DNA hypomethylation at pericentromeric satellite-2 and -3 repeats in chromosomes 1, 9 and 16. ICF syndrome is classified into two groups: type 1 (ICF1) patients have mutations in the DNMT3B gene and about half of type 2 (ICF2) patients have mutations in the ZBTB24 gene. Besides satellite-2 and -3 repeats, α-satellite repeats are also hypomethylated in ICF2. In this study, we report three novel ZBTB24 mutations in ICF2. A Japanese patient was homozygous for a missense mutation (C383Y), and a Cape Verdean patient was compound heterozygous for a nonsense mutation (K263X) and a frame-shift mutation (C327W fsX54). In addition, the second Japanese patient was homozygous for a previously reported nonsense mutation (R320X). The C383Y mutation abolished a C2H2 motif in one of the eight zinc-finger domains, and the other three mutations caused a complete or large loss of the zinc-finger domains. Our immunofluorescence analysis revealed that mouse Zbtb24 proteins possessing a mutation corresponding to either C383Y or R320X are mislocalized from pericentrometic heterochromatin, suggesting the importance of the zinc-finger domains in proper intranuclear localization of this protein. We further revealed that the proper localization of wild-type Zbtb24 protein does not require DNA methylation. PMID:23739126

    Background The aim of this study is to analyze if there is a relationship between adherence to antipsychotic medication and rehospitalization for patients diagnosed with schizophrenia in Japan. Methods Based on Japanese claims data, we constructed three patient groups based on their medication possession ratio (MPR). Controlling for potential confounders, a Cox proportional hazard model was employed to assess if medication adherence affects the risk of rehospitalization. Results Patients with good adherence (MPRs from 0.8–1.1) had the lowest rates of admission. Both poor adherence (MPRs <0.8) and overadherence (MPRs >1.1) were associated with a significant higher risk of rehospitalization with hazard ratios of 4.7 and 2.0, respectively. Conclusion The results of this study support the notion that good adherence to antipsychotic medication reduces the risk of rehospitalization of schizophrenia patients. Appropriate measures should be taken to improve adherence of schizophrenia patients. PMID:25897229

    Cultural competence requires sensitivity to the diverse ethnic, religious, and cultural expectations of patients in our health care system. In the increasingly multicultural world of the city hospital, patients will benefit from increased cultural competency on the part of health care providers. This study interviews Japanese, Korean, and Indian immigrants to the United States, showing that these individuals hold vastly different expectations concerning: 1) when to seek medical assistance; 2) the role of the doctor in the community; 3) the role of the patient and the patient's family in conversations with the medical specialist; 4) the roles of doctors versus nurses; 5) issues of privacy and disclosure to patient and family; 6) organ donation; and 7) end-of-life care. The paper concludes with immigrants' views on what would make their medical experience in the United States more comfortable, and hence, potentially more beneficial to their mental and physical health.

    Purpose To assess the importance of inflammation in chronic obstructive pulmonary disease (COPD) by measuring airway and systemic inflammatory biomarkers in Japanese patients with the disease and relevant control groups. Patients and methods This was the first study of its type in Japanese COPD patients. It was a non-treatment study in which 100 participants were enrolled into one of three groups: nonsmoking controls, current or ex-smoking controls, and COPD patients. All participants underwent standard lung function assessments and provided sputum and blood samples from which the numbers of inflammatory cells and concentrations of biomarkers were measured, using standard procedures. Results The overall trends observed in levels of inflammatory cells and biomarkers in sputum and blood in COPD were consistent with previous reports in Western studies. Increasing levels of neutrophils, interleukin 8 (IL-8), surfactant protein D (SP-D), and Krebs von den Lungen 6 (KL-6) in sputum and clara cell 16 (CC-16), high-sensitivity C-reactive protein (hs-CRP), and KL-6 in serum and plasma fibrinogen were seen in the Japanese COPD patients compared with the non-COPD control participants. In sputum, significant correlations were seen between total cell count and matrix metalloproteinase 9 (MMP-9; P<0.001), neutrophils and MMP-9 (P<0.001), macrophages and KL-6 (P<0.01), total cell count and IL-8 (P<0.05), neutrophils and IL-8 (P<0.05), and macrophages and MMP-9 (P<0.05). Significant correlations were also observed between some inflammatory cells in sputum and biomarkers in serum, with the most significant between serum CC-16 and both total cell count (P<0.005) and neutrophils (P<0.005) in sputum. Conclusion These results provide evidence for the first time that COPD in Japanese patients is a multicomponent disease, involving both airway and systemic inflammation, in addition to airway obstruction. Therefore, intervention with anti-inflammatory therapy may provide additional

    Enzyme replacement therapy (ERT) with exogenous glucocerebrosidase is indicated to treat symptomatic Gaucher disease (GD), a rare, inherited metabolic disorder. ERT with velaglucerase alfa, which is produced in a human cell line using gene activation technology, was studied in a 12-month phase III trial in Japanese patients with type 1 or 3 GD who were switched from imiglucerase ERT (n=6); the current, open-label, 12-month extension study was designed to assess longer-term safety and efficacy. Two adult and three pediatric patients (aged <18years) were enrolled into the extension study. Every-other-week intravenous infusions were administered for 63-78weeks at average doses between 51.5 and 60.7units/kg. Three non-serious adverse events were considered related to velaglucerase alfa treatment, but no patient discontinued from the study. Six serious but non-drug-related adverse events were reported. No patient tested positive for anti-velaglucerase alfa antibodies. Hemoglobin concentrations, platelet counts, and liver and spleen volumes (normalized to body weight) in these patients were generally stable over a cumulative 24-month period from the baseline of the parent trial. The data suggest that velaglucerase alfa was well tolerated and maintained clinical stability in Japanese GD patients over 2years after switching from imiglucerase.

    "Hie" is a subjective oversensitivity to cold and a condition experienced in 60% of Japanese citizens. The condition of hie has not been documented in Western medicine. However, in Kampo medicine, hie is an important target of treatment, because it has been considered one of the sources of all kinds of diseases. This study aimed to clarify the symptoms and findings associated with hie and contribute to increased precision in hie diagnosis. During 2005-2006, data from interviews of 1691 patients during their initial visit to the Kampo Clinic of Keio University Hospital were analyzed using a classification and regression tree (CART) analysis, a data mining technique. Symptoms and findings characteristic of each group are follows as, postmenopausal women: fatigability, absence of lower abdominal pain, and absence of hot flashes of feet: women with menstruation: leg swelling, knee pain, and abdominal pain; men: insomnia, leg weakness, and absence of excess saliva. From the perspective of Kampo medicine the result suggested that the feature of hie condition in postmenopausal women, women with menstruation, and men is statistically different. PMID:24707313

    Citrullinemia is an autosomal recessive disease caused by a genetic deficiency of argininosuccinate synthetase. In order to characterize mutations in Japanese patients with classical citrullinemia, RNA isolated from 10 unrelated patients was reverse-transcribed, and cDNA amplified by PCR was cloned and sequenced. The 10 mutations identified included 6 missense mutations (A118T, A192V, R272C, G280R, R304W, and R363L), 2 mutations associated with an absence of an exon 7 or exon 13, 1 mutation with a deletion of the first 7 bp in exon 16 (which might be caused by abnormal splicing), and 1 mutation with an insertion of 37 bp within exons 15 and 16 in cDNA. The insertion mutation and the five missense mutations (R304W being excluded) are new mutations described in the present paper. These are in addition to 14 mutations (9 missense mutations, 4 mutations associated with an absence of an exon in mRNA, and 1 splicing mutation) that we identified previously in mainly American patients with neonatal citrullinemia. Two of these 20 mutations, a deletion of exon 13 sequence and a 7-bp deletion in exon 16, were common to Japanese and American populations from different ethnic backgrounds; however, other mutations were unique to each population. Furthermore, the presence of a frequent mutation - the exon 7 deletion mutation in mRNA, which accounts for 10 of 23 affected alleles - was demonstrated in Japanese citrullinemia. This differs from the situation in the United States, where there was far greater heterogeneity of mutations.

    A retrospective study was conducted on 126 patients with rhabdomyosarcoma enrolled in the Japanese Pediatric Tumor Registry between 1971 and 1980. The age of the patients ranged from less than 1 year to 15 years, and the male to female ratio was 1.3:1.0. Primary sites included the pelvis (37.3 per cent), abdomen (23.8 per cent), head and neck (21.4 per cent), thorax (9.5 per cent), extremities (6.4 per cent) and unknown (1.6 per cent). According to the staging system of the Japanese Society of Pediatric Surgeons, the extent of disease was classified into stages Ia (26.2 per cent of the total); Ib (14.6 per cent); II (12.6 per cent), III (29.1 per cent) and IV (17.5 per cent). The clinical stage was significantly correlated with survival outcome in this series (p less than 0.05). Age, sex, histology and primary site per se had no independent prognostic influence on tumor-free survival. With regard to treatment modalities, surgery was performed in 94.0 per cent of the patients, and radiotherapy at a mean dose of 37 Gy, and/or multi-agent chemotherapy in 41.7 per cent and 80.0 per cent, respectively. The patients who underwent total excision had a better survival outcome than those who did not (p less than 0.05). Combination chemotherapy such as VAC was more commonly administered in the latter study period. The overall 2-year tumor-free survival rate (2YTFSR) significantly improved from 24.0 per cent in the former period between 1971 and 1975 to 48.7 per cent in the latter period between 1976 and 1980 (p less than 0.05).

    Netherton syndrome (NS) is a rare autosomal recessive disorder which is caused by mutations in the SPINK5 gene encoding the serine-protease inhibitor LEKTI. Characteristic symptoms of NS include erythroderma with diffuse desquamation, hair abnormalities and atopic manifestations. Here, we report two Japanese patients with NS, one of whom had a novel mutation in the SPINK5 gene which leads to p.C367Lfs*3. The upregulation of interleukin-33 (IL-33) was evident in basal and thickened lower spinous layers of the epidermis in those cases. This suggests that IL-33 may be involved in the pathophysiology of NS as well as in atopic dermatitis. PMID:24506793

    OBJECTIVE To investigate whether diabetes and regular hemodialysis are associated with false elevation of ankle systolic blood pressure and ankle-brachial systolic pressure index (ABI) because of their arterial calcification in patients with critical limb ischemia (CLI). RESEARCH DESIGN AND METHODS We recruited 269 Japanese patients who underwent endovascular therapy for CLI. Ankle systolic blood pressure and ABI were assessed before endovascular therapy. Arterial stenosis and calcification were evaluated angiographically. We investigated the associations among clinical comorbidities, arterial calcification, and measurements of ankle systolic blood pressure and ABI. RESULTS Ankle systolic blood pressure was 85 ± 56 mmHg, and ABI was 0.59 ± 0.37. Arterial calcification was observed in 69% of the patients. The prevalence of diabetes and regular hemodialysis was 71 and 47%. Diabetes and regular hemodialysis were both significantly associated with the presence of arterial calcification; their adjusted odds ratios were 2.33 (P = 0.01) and 7.40 (P < 0.01), respectively. However, there was no significant difference in ankle systolic blood pressure or ABI level between those with and without these comorbidities. Furthermore, the presence of arterial calcification was not associated with ankle systolic blood pressure or ABI level, whereas arterial stenoses of all segments in the lower body had independent associations with reduced ankle systolic blood pressure and ABI level. CONCLUSIONS Diabetes and regular hemodialysis were significantly associated with arterial calcification, but not with elevated measurements of ankle systolic blood pressure or ABI, in CLI patients.

    An increasing number of pediatric cancer patients survive, and treatment-related infertility represents one of the most important issues for these patients. While official guidelines in Japan recommend long-term follow-up of childhood cancer survivors (CCSs), their gonadal function and fertility have not been clarified. To address this issue, we organized a working panel to compile evidence from long-term survivors who received treatments for cancer during childhood or adolescence. In collaboration with members of the CCS Committee of the Japanese Society for Pediatric Endocrinology (JSPE), we conducted a questionnaire survey regarding reproductive function in pediatric cancer patients. A cross-sectional survey was sent to 178 JSPE-certified councilors who were asked to self-evaluate the medical examinations they had performed. A total of 151 responses were obtained, revealing that 143 endocrinologists were involved in the care of CCSs. A quarter of the respondents reported having experienced issues during gonadal or reproductive examinations. Several survivors did not remember or fully understand the explanation regarding gonadal damage, and faced physical and psychological distress when discussing the risk of becoming infertile. Pediatric endocrinologists had anxieties regarding their patients' infertility and the risk of miscarriage, premature birth, and delivery problems. Only a limited number of endocrinologists had experience with managing childbirth and fertility preservation. Many councilors mentioned the necessity for inter-disciplinary communication among healthcare providers. Both endocrinologists and oncologists should set and follow a uniform clinical guideline that includes management of fertility of CCSs. PMID:27212796

    In Japan, osteoarthritis (OA) of the hip secondary to acetabular dysplasia is very common, and there are few data concerning the pathogeneses and incidence of femoroacetabular impingement (FAI). We have attempted to clarify the radiological prevalence of painful FAI in a cohort of Japanese patients and to investigate the radiological findings. We identified 176 symptomatic patients (202 hips) with Tönnis grade 0 or 1 osteoarthritis, whom we prospectively studied between August 2011 and July 2012. There were 61 men (65 hips) and 115 women (137 hips) with a mean age of 51.8 years (11 to 83). Radiological analyses included the α-angle, centre-edge angle, cross-over sign, pistol grip deformity and femoral head neck ratio. Of the 202 hips, 79 (39.1%) had acetabular dysplasia, while 80 hips (39.6%) had no known aetiology. We found evidence of FAI in 60 hips (29.7%). Radiological FAI findings associated with cam deformity were the most common. There was a significant relationship between the pistol grip deformity and both the α-angle (p < 0.001) and femoral head-neck ratio (p = 0.024). Radiological evidence of symptomatic FAI was not uncommon in these Japanese patients. PMID:24493180

    Physical and sexual abuse among patients with eating disorders has been a focus of attention in Western countries, however, there is no study comparing the incidence of these factors in Western and Asian countries. Japanese subjects consisted of 38 patients with anorexia nervosa restricting type (AN-R), 46 patients with anorexia nervosa binge eating/purging type (AN-BP), 76 patients with bulimia nervosa purging type (BN) and 99 controls. Subjects from the USA consisted of 29 AN-R, 34 AN-BP and 16 BN. The Physical and Sexual Abuse Questionnaire was administered to all subjects. Minor sexual abuse such as confronting exhibitionism or being fondled by a stranger tended to be more prevalent among Japanese subjects, while victimization by rape or incest was more prevalent among USA subjects. Conversely, physical abuse history was similarly distributed across each diagnostic subgroup in both countries. Events related to physical abuse, such as an abusive family background, may contribute whether eating disorder patients are restricting or bulimic and regardless of culture. PMID:11442883

    Objective. The objective of this study was to describe the recent clinical characteristics of labor using 3 systems of Japanese midwife-led primary delivery care, as follows: (1) those intending to give birth at home managed by midwives who do not belong to our hospital, (2) those planning to give birth in our hospital managed by the same midwives, and (3) those planning to give birth managed by midwives who belong to our hospital. Methods. A retrospective cohort study was performed. Results. There were no significant differences in the obstetric or neonatal outcomes among the 3 groups. The rate of transfers during labor with the system involving midwives belonging to our hospital was higher than those with the other 2 systems. In addition, the timing of transfers in the system with the midwives belonging to our hospital was earlier than with the other 2 systems. Among the 3 groups, there were no significant differences in the rate of the main 2 indications for transfers: fetal heart rate abnormality and failure to progress. Conclusion. There were no significant differences in perinatal outcomes among the 3 systems; however, there were some differences in the status of transfers to obstetric shared care. PMID:27034827

    Olaratumab (IMC-3G3) is a fully human IgG1 monoclonal antibody that selectively binds the external domain of human platelet-derived growth factor receptor-α with high affinity and blocks ligand binding. This was a single-center, dose-escalation, phase I trial of olaratumab in Japanese patients with advanced/refractory solid malignancies. Three to six patients were enrolled into each of three cohorts: Patients received i.v. olaratumab: 10 mg/kg on days 1 and 8 every 3 weeks (cohort 1); 20 mg/kg every 2 weeks (cohort 2); and 15 mg/kg on days 1 and 8 every 3 weeks (cohort 3). Doses were escalated from cohort 1 through cohort 3. The primary objective was to establish the safety and pharmacokinetic profile of olaratumab. Sixteen patients were treated across three cohorts. There were no dose-limiting toxicities, so the maximum tolerated dose was not reached. The most common olaratumab-related treatment-emergent adverse events (TEAEs) were proteinuria (25.0%) and elevated aspartate transaminase (12.5%). One patient (cohort 2) had two olaratumab-related Grade 3 TEAEs (increased aspartate aminotransferase and tumor hemorrhage); otherwise, olaratumab-related TEAEs were Grade 1/2. Seven patients (43.8%) had a best response of stable disease. Based on the pharmacokinetic concentration profile of olaratumab, the trough concentrations following single and multiple doses at 15 mg/kg on days 1 and 8 every 3 weeks (cohort 3) and multiple doses at 20 mg/kg every 2 weeks (cohort 2) were above the 155 μg/mL target. Thus, these two doses could represent an acceptable schedule for future trials in Japanese patients. Olaratumab had an acceptable safety profile and was well tolerated. PMID:24816152

    To identify our role and the customers' satisfaction, the on-call consultation service records of the Department of Clinical Pathology, Nihon University School of Medicine, Itabashi Hospital (NUIH), were analyzed. Between 1995 and 1998, 1,789 consultation services were recorded, and approximately 40% were from physicians, and 50% were from medical technologists. During office hours, many physicians made contact with us at the office of clinical pathology, the clinical laboratory and other places in the hospital by various means. They asked us to interpret multidisciplinary laboratory data, and to provide the specific information that might affect clinical management. Medical technologists asked for clinical information of patients with extreme measured values and requested that we contact with physicians. In contrast, on weekends/holidays or after routine working hours, physicians sometimes requested non-automated laboratory tests such as peripheral blood smears/bone marrow smears or Gram stains. The major contents of our responses to medical technologists were concerned with blood banking and handling of instruments not to be operated in routine work. These results reconfirm that we are still required to have clinical competence for common laboratory procedures and to have the capability of interpretation of multidisciplinary laboratory data in the university hospital. Traditionally, most Japanese clinical pathologists have been focused their attention on bench work in research laboratories. However, the present study shows that the clinical pathologists need to bridge the real gap between laboratory technology and patient care. Our on-call service system can enhance the education of clinical pathologists, and improve not only laboratory quality assurance but also patient care. In addition, in response to a need for customer access to this service with a shortage of clinical pathologists, a more effective method would be to set up a proactive systemic approach in

    A practical quality-of-life measure applicable to patients with skin diseases is necessary. Recently developed dermatological quality-of-life measures must be translated and adapted for use in cultures other than the ones in which they were created. In this study, we translated and adapted culturally into Japanese a skin-disease-specific, brief quality-of-life measure, Skindex-16, and studied its reliability and validity. Forward-and back-translations of Skindex-16 were carried out. Six doubtful items as well as the term "skin condition" required a second forward- and back-translation to reach satisfactory agreement with the original instrument. Cross-cultural adaptation and cross-sectional questionnaire studies were then performed to evaluate the reliability and validity of the instrument. One hundred patients and 30 healthy adults responded to the Japanese version. The internal-consistency reliability of the final Japanese version of Skindex-16 was high (range of Cronbach's alpha for each scale, symptoms, emotions, and functioning, was 0.83-0.92). The Japanese version showed construct and content validity. As hypothesized, scores for dermatological patients were higher than those for healthy persons (mean global scores 36 +/- 23 vs 1 +/- 2, p < 0.001) and scores for patients with inflammatory diseases were higher than those for patients with isolated skin lesions (mean global scores 48 +/- 21 vs 22 +/- 17, p < 0.001), indicating a poorer quality of life. Most patients' responses to an open-ended question about their skin disease were similar to those of the American responders and were addressed according to the items. In conclusion, we have developed a semantically equivalent translation of Skindex-16 into Japanese. It is a reliable and valid measure of the effects of skin disease on the quality of life in Japanese patients. PMID:12484430

    We conducted a 26-week oral-administration study of ranirestat (an aldose reductase inhibitor) at a once-daily dose of 20 mg to evaluate its efficacy and safety in Japanese patients with diabetic polyneuropathy (DPN). The primary endpoint was summed change in sensory nerve conduction velocity (NCV) for the bilateral sural and proximal median sensory nerves. The sensory NCV was significantly (P = 0.006) improved by ranirestat. On clinical symptoms evaluated with the use of modified Toronto Clinical Neuropathy Score (mTCNS), obvious efficacy was not found in total score. However, improvement in the sensory test domain of the mTCNS was significant (P = 0.037) in a subgroup of patients diagnosed with neuropathy according to the TCNS severity classification. No clinically significant effects on safety parameters including hepatic and renal functions were observed. Our results indicate that ranirestat is effective on DPN (Japic CTI-121994). PMID:26881251

    Background Gender differences in clinical outcomes after percutaneous coronary intervention (PCI) among different age groups are controversial in the era of drug-eluting stents, especially among the Asian population who are at higher risk for bleeding complications. Methods and Results We analyzed data from 10,220 patients who underwent PCI procedures performed at 14 Japanese hospitals from September 2008 to April 2013. A total of 2,106 (20.6%) patients were women. Women were older (72.7±9.7 vs 66.6±10.8 years, p<0.001), and had a lower body mass index (23.4±4.0 vs 24.3±3.5, p<0.001), with a higher prevalence of hypertension (p<0.001), hyperlipidemia (p<0.001), insulin-dependent diabetes (p<0.001), renal failure (p<0.001), and heart failure (p<0.001) compared with men. Men tended to have more bifurcation lesions (p = 0.003) and chronic totally occluded lesions (p<0.001) than women. Crude overall complications (14.8% vs 9.5%, p<0.001) and the rate of bleeding complications (5.3% vs 2.8%, p<0.001) were significantly higher in women than in men. On multivariate analysis in the total cohort, female sex was an independent predictor of overall complications (OR, 1.47; 95% CI, 1.26–1.71; p<0.001) and bleeding complications (OR, 1.74; 95% CI, 1.36–2.24; p<0.001) after adjustment for confounding variables. A similar trend was observed across the middle-aged group (≥55 and <75 years) and old age group (≥75 years). Conclusions Women are at higher risk than men for post-procedural complications after PCI, regardless of age. PMID:25635905

    The SLITRK1 (Slit and Trk-like 1) gene has been suggested to be a promising candidate for Tourette syndrome (TS) since the first report that identified its two rare variants adjacent to the chromosome inversion in a TS child with inv(13) (q31.1;q33.1). A series of replication studies have been carried out, whereas the role of the gene has not been elucidated. The present study aimed to determine whether the two or novel nonsynonymous variants were identified in Japanese TS patients and carry out an association analysis of the gene in a Japanese population. We did not observe the two or any novel nonsynonymous variants in the gene. In contrast, a significant difference was observed in the distributions of the haplotypes consisting of rs9546538, rs9531520, and rs9593835 between the patients and the controls. This result may partially support the implication of SLITRK1 in the pathogenesis of TS, warranting further studies of the gene. PMID:26317387

    The current study investigated physicians' awareness and use of the Japanese Society of Hypertension Guidelines for the Management of Hypertension 2014 (JSH2014) and is based on the results of a survey performed by the Publicity and Advertisement Committee of JSH. A questionnaire was used to survey physicians' awareness of the JSH2014, their recommended target blood pressure for hypertensive patients with complications and their use of antihypertensive drugs. Physicians who downloaded a PDF version of JSH2014 during the 6 months after its publication (April-September 2014) were asked to complete an online questionnaire. Of the 7872 respondents, 91% were aware of the JSH and complied partially, mostly or completely with it in their practice. With reference to hypertensive patients, ∼70% of physicians who completed the questionnaire recommended a target blood pressure (BP) of 140/90 mm Hg for an office BP value, and 40% recommended 135/85 mm Hg for a home BP value. Physicians recommended target BP levels of 130/80 mm Hg for patients with diabetes or chronic kidney disease (50-63% of physician surveyed) and for elderly patients with diabetes or kidney disease (45-55% of respondents), whereas they recommended 140/90 mm Hg for elderly patients with low cardiovascular disease risk (56-60% of physician surveyed) and for patients with chronic-phase stroke (40-47% of respondents). The most commonly prescribed combination of antihypertensive drugs was angiotensin receptor blocker (ARB) with calcium channel blocker. In addition, physicians' first choice of drug for patients with diabetes or chronic kidney disease was most often ARB. Overall, the survey results showed that the new recommendations from the JSH2014 accurately reflect daily clinical practices for hypertension management used by Japanese physicians. PMID:27169398

    There have been few coherent reports on extraintestinal infection or bacteremia caused by Campylobacter jejuni (C. jejuni) or C. coli in Japan. To clarify the clinical and microbiological characteristics of invasive infections caused by these two species, we retrospectively analyzed the records of patients from whom these pathogens had been isolated from sterile sites between 2000 and 2015. During this study period, we identified 9 patients. The clinical syndrome of all of these patients was bacteremia. Three patients had underlying diseases with both liver cirrhosis and malignant neoplasm, and all of these patients were aged 60 years or older. The remaining 6 patients were immunocompetent and younger than 40 years of age. All 9 patients had a fever of 38.5 degrees C or higher. The proportion of patients with gastrointestinal symptoms was lower for the 3 patients with underlying diseases, compared with the 6 patients without underlying diseases (1/3 cases vs, 4/6 cases). Of the 8 strains evaluated for antimicrobial susceptibility, all were susceptible to imipenem/cilastatin, kanamycin and erythromycin, and 2 were resistant to levofloxacin. Antimicrobial treatment was administered to 8 patients, but one spontaneously recovered without any treatment. We were able to follow the outcomes of 8 patients, and all of these patients completely recovered without relapses. We also reviewed 14 Japanese patients reported in the Japanese and English literature and found similar clinical features consisting of a high-grade fever and an association with underlying diseases and gastrointestinal symptoms. Of note, 3 agammaglobulinemic patients presented with bacteremia and extraintestinal infections and had multiple relapses. Based on the findings of our 9 cases and previous reports, the affected patients were divided into two groups according to clinical syndrome and therapeutic intervention. One group consisted of previously healthy children or young adults showing bacteremia

    Abstract. An increasing number of pediatric cancer patients survive, and treatment-related infertility represents one of the most important issues for these patients. While official guidelines in Japan recommend long-term follow-up of childhood cancer survivors (CCSs), their gonadal function and fertility have not been clarified. To address this issue, we organized a working panel to compile evidence from long-term survivors who received treatments for cancer during childhood or adolescence. In collaboration with members of the CCS Committee of the Japanese Society for Pediatric Endocrinology (JSPE), we conducted a questionnaire survey regarding reproductive function in pediatric cancer patients. A cross-sectional survey was sent to 178 JSPE-certified councilors who were asked to self-evaluate the medical examinations they had performed. A total of 151 responses were obtained, revealing that 143 endocrinologists were involved in the care of CCSs. A quarter of the respondents reported having experienced issues during gonadal or reproductive examinations. Several survivors did not remember or fully understand the explanation regarding gonadal damage, and faced physical and psychological distress when discussing the risk of becoming infertile. Pediatric endocrinologists had anxieties regarding their patients’ infertility and the risk of miscarriage, premature birth, and delivery problems. Only a limited number of endocrinologists had experience with managing childbirth and fertility preservation. Many councilors mentioned the necessity for inter-disciplinary communication among healthcare providers. Both endocrinologists and oncologists should set and follow a uniform clinical guideline that includes management of fertility of CCSs. PMID:27212796

    An A-to-G mutation at nucleotide position 3243 of the mitochondrial genome has been associated with insulin-dependent diabetes mellitus (IDDM) and with noninsulin-dependent diabetes mellitus (NIDDM) with deafness. We investigated the prevalence of this mutation in Japanese patients with IDDM, NIDDM, and impaired glucose tolerance (IGT) and in nondiabetic control individuals, and we identified it in 3 of 300 patients with NIDDM or IGT (1.0%). None of these individuals had significant sensorineural hearing loss. None of the 94 IDDM or the 115 nondiabetic control subjects was positive for this mutation. Oral glucose tolerance test revealed that a 57-yr-old male with this mutation was rather hyperinsulinemic in the fasting state. The insulin secretion in this patient decreased with age; he did not complain of any hearing disorder, although audiometry revealed a slight elevation of hearing threshold at high frequencies. In conclusion, we found that a mitochondrial gene mutation at nucleotide position 3243 was present in about 1% of NIDDM patients including those patients with IGT. The subtype of diabetes mellitus with this mutation may have a clinical profile similar to that found in patients with NIDDM commonly seen in outpatient clinics. 25 refs., 2 figs., 1 tab.

    Objective Recent evidence in cultural and social psychology suggests Eastern cultures' emphasis on harmony and connection with others and Western cultures' emphasis on self-direction and autonomy. In Eastern society, relational harmony is closely linked to people's well-being. The impact of this cultural and social orientation on diabetes-related distress was investigated. Research Design and Methods Japanese and American patients with type 2 diabetes were surveyed by well-established questionnaire in Japan and in the United States, respectively. The association of personal values for interdependence, perceived emotional support, and the Problem Areas in Diabetes scale (PAID) were analyzed. Results A positive correlation between interdependence and PAID (r = 0.18; P = 0.025) and a negative correlation between perceived emotional support and PAID (r = − 0.24; P = 0.004) were observed after adjustments for other factors in Japanese data (n = 149), but not in American data (r = 0.00; P = 0.990, r = 0.02; P = 0.917, respectively, n = 50). In Japanese data, the three-factor structure of PAID (negative feelings about total life with diabetes, about living conditions with diabetes, and about treatment of diabetes) was identified, and interdependence showed significant positive correlations with the first and second factors and perceived emotional support showed significant negative correlations with all three factors of PAID. Conclusions These results suggest that personal values for interdependence may be linked to the level of diabetes-related distress and that the distress may be relieved by perception of emotional support, especially in an interdependent cultural context.

    Stickler syndrome is an inherited connective tissue disorder that affects the eyes, cartilage and articular tissues. The phenotypes of Stickler syndrome include congenital high myopia, retinal detachment, premature joint degeneration, hearing impairment and craniofacial anomalies, such as cleft palate and midline facial hypoplasia. The disease is genetically heterogeneous, and the majority of the cases are caused by mutations in the COL2A1 gene. We examined 40 Japanese patients with Stickler syndrome from 23 families to determine whether they had mutations in the COL2A1 gene. This analysis was conducted by examining each patient's genomic DNA by Sanger sequencing. Five nonsense, 4 splicing and 8 deletion mutations in the COL2A1 gene were identified, accounting for 21 of the 23 families. Different mutations of the COL2A1 gene were associated with similar phenotypes but with different degrees of expressivity. PMID:27408751

    Congenital heart disease (CHD) is the most common birth defect occurring in humans and some transcriptional factors have been identified as causative. However, additional mutation analysis of these genes is necessary to develop effective diagnostic and medical treatment methods. We conducted sequence analysis of the coding regions of NKX2.5, GATA4, TBX1, TBX5, TBX20, CFC1 and ZIC3 in 111 Japanese patients with non-syndromic CHD and 9 of their relatives. All patient samples were also analyzed by multiplex ligation-dependent probe amplification using probes involved in chromosome deletion related to CHD. Five novel variations of TBX5, GATA4 and TBX20 were detected in 6 of the patients, whereas none were found in 200 controls. The TBX5 variation p.Pro108Thr, located in the T-box domain, was identified in a patient with tricuspid atresia, an exon-intron boundary variation of GATA4 (IVS4+5G>A) was detected in a Tetralogy of Fallot patient and an 8p23 microdeletion was detected in one patient with atrioventricular septal defect and psychomotor delay. A total of seven non-synonymous polymorphisms were found in the patients and controls. Accumulation of novel variations of genes involving the cardiac development may be required for better understanding of CHD. PMID:26490186

    Drug-induced liver injury (DILI) is a common adverse drug reaction in patients receiving antituberculosis (anti-TB) treatment. Among the anti-TB agents, isoniazid (INH) is the primary drug that causes hepatotoxicity in TB patients with DILI. Previous reports in several populations have consistently demonstrated an association between polymorphisms in the N-acetyltransferase 2 (NAT2) gene, which is responsible for INH hepatic metabolism, and a risk of DILI in TB patients. In this study, the genetic and baseline clinical data from 366 Japanese patients with TB (73 patients with DILI and 293 without DILI) were used to develop a system to predict DILI risk due to anti-TB agents. The distribution of the NAT2 acetylator status among the TB patients with DILI was 31 (42.5%), 29 (39.7%), and 13 (17.8%) for rapid, intermediate, and slow acetylators, respectively. A significant association was observed between NAT2 slow acetylators and DILI risk (odds ratio 4.32, 95% confidence interval 1.93–9.66, P value=5.56×10−4). A logistic regression model based on age and NAT2 genotype revealed that the area under the curve for the receiver-operating characteristic curve was 0.717. The findings demonstrated that slow NAT2 acetylator status is a significant predictor of the risk of DILI by anti-TB agents, and a personalized anti-TB treatment approach may aid in making treatment decisions and reducing the incidence of DILI.

    Japanese encephalitis (JE) is numerically the most important global cause of encephalitis and so far confirmed to have caused major epidemics in India. Most of the reported studies have been in children. This largest study involving only adults, belonging to four epidemics, is being reported from Gorakhpur. The aim of this study is to detail the acute clinical profile (not viral) outcome and to classify the sequelae at discharge. This prospective study involved 1,282 adult patients initially diagnosed as JE admitted during the epidemics of 1978, 1980, 1988, and 1989, on identical clinical presentation and CSF examination. In the meantime, the diagnosis of JE was confirmed by serological and/or virological studies in only a representative number of samples (649 of 1,282 cases). Eighty-three left against medical advice (LAMA) at various stages, so 1,199 of 1,282 were available for the study. Peak incidence of [1,061 of 1,282 (83%)] of clinically suspected cases was from September 15 to November 2. Serum IgM and IgG were positive in high titers in 50.87% (330 of 649) and IgM positive in CSF in 88.75% (109 of 123) of the cases. JE virus could be isolated from CSF and brain tissue in 5 of 5 and 4 of 5 samples, respectively. Altered sensorium (AS) in (96%), convulsions (86%), and headache (85%) were the main symptoms for hospitalization by the third day of the onset. Other neurological features included hyperkinetic movements in 593 of 1,282 (46%)-choreoathetoid in 490 (83%) and bizarre, ill-defined in 103 (17%). The features of brain stem involvement consisted of opsoclonus (20%), gaze palsies (16%), and pupillary changes (48%) with waxing and waning character. Cerebellar signs were distinctly absent. Dystonia and decerebrate rigidity was observed in 43 and 6%, respectively, paralytic features in 17% and seizures in 30%. Many non-neurological features of prognostic importance included abnormal breathing patterns (ABP) (45%), pulmonary edema (PO) (33%), and upper

    2012-01-01

    Background Patient safety education, including error prevention strategies and management of adverse events, has become a topic of worldwide concern. The importance of the patient safety is also recognized in Japan following two serious medical accidents in 1999. Furthermore, educational curriculum guideline revisions in 2008 by relevant the Ministry of Education includes patient safety as part of the core medical curriculum. However, little is known about the patient safety education in Japanese medical schools partly because a comprehensive study has not yet been conducted in this field. Therefore, we have conducted a nationwide survey in order to clarify the current status of patient safety education at medical schools in Japan. Results Response rate was 60.0% (n = 48/80). Ninety-eight-percent of respondents (n = 47/48) reported integration of patient safety education into their curricula. Thirty-nine percent reported devoting less than five hours to the topic. All schools that teach patient safety reported use of lecture based teaching methods while few used alternative methods, such as role-playing or in-hospital training. Topics related to medical error theory and legal ramifications of error are widely taught while practical topics related to error analysis such as root cause analysis are less often covered. Conclusions Based on responses to our survey, most Japanese medical schools have incorporated the topic of patient safety into their curricula. However, the number of hours devoted to the patient safety education is far from the sufficient level with forty percent of medical schools that devote five hours or less to it. In addition, most medical schools employ only the lecture based learning, lacking diversity in teaching methods. Although most medical schools cover basic error theory, error analysis is taught at fewer schools. We still need to make improvements to our medical safety curricula. We believe that this study has the implications for

    The aim of this study was to clarify how painful physical symptoms affect treatment outcomes in patients with melancholic major depressive disorder. The subjects comprised 100 consecutive Japanese outpatients with melancholic major depressive disorder who visited our clinic from October 2011 to October 2014. All subjects were interviewed for Diagnostic and Statistical Manual of Mental Disorders Axis 2, 3, and 4 and family history of major depressive disorder, and then grouped according to the presence of painful physical symptoms. We evaluated painful physical symptoms at baseline and after 12, 24, and 36 weeks of treatment and scores on the 17-item Hamilton Rating Scale for Depression, compared major depressive disorder remission between groups, and assessed responsiveness to antidepressants. The group with painful physical symptoms had a significantly more positive family history of major depressive disorder. The major depressive disorder remission rate was high in both groups, and no significant differences were observed. However, a significant relationship between major depressive disorder and painful physical symptoms remission was observed in the group with painful physical symptoms. A significantly higher number of remitted patients with painful physical symptoms (N=61) were administered serotonin-noradrenaline reuptake inhibitors, with significantly more receiving duloxetine than milnacipran.

    The efficacy and tolerability of once weekly dulaglutide 0.75 mg in Japanese patients with type 2 diabetes (T2D) were evaluated by subgroups defined by key demographic characteristics. This post hoc analysis included data from patients who received dulaglutide 0.75 mg for up to 26 weeks in three phase 3 trials (one open-label, randomized; one double-blind and open-label, randomized; one open-label, nonrandomized). Patients were classified into subgroups on the basis of sex (male, female), age (<65, ≥65 years), body weight (<70, ≥70 kg), body mass index (BMI; <25, ≥25 kg/m(2)), duration of diabetes (<7, ≥7 years), HbA1c (≤8.5, >8.5%), use of concomitant sulfonylurea (yes, no), and use of concomitant biguanide (yes, no). Efficacy measures analyzed were changes from baseline in HbA1c and body weight and percentages of patients achieving HbA1c <7.0%. Safety measures analyzed were incidence of hypoglycemia and nausea and change from baseline in seated pulse rate. A total of 855 patients were analyzed. Once weekly dulaglutide 0.75 mg improved blood glucose control as measured by HbA1c regardless of patient characteristics; patients with higher baseline HbA1c values had greater improvements compared to patients with lower baseline values. Weight loss was greater in patients with lower baseline HbA1c and in patients taking concomitant biguanides. Concomitant use of sulfonylureas had the greatest effect on the incidence of hypoglycemia. Treatment of T2D with once weekly dulaglutide 0.75 mg for 26 weeks was associated with significant improvement in glycemic control irrespective of age, sex, duration of diabetes, body weight, BMI, or concomitant medication.

    This phase I trial conducted in Japanese patients with acute myeloid leukemia evaluated the safety, maximum tolerated dose and pharmacokinetics of volasertib (BI 6727), a selective Polo-like kinase inhibitor. The primary endpoints were the maximum tolerated dose of volasertib and the incidence of dose-limiting toxicities. Secondary endpoints were best response and remission duration. Other endpoints included safety and pharmacokinetics. Patients who were ineligible for standard induction therapy or with relapsed or refractory disease received volasertib monotherapy as a 2-h infusion on days 1 and 15 of a 28-day cycle, with dose escalation following a 3 + 3 design. A total of 19 patients were treated with three volasertib doses: 350, 400 and 450 mg. One patient receiving volasertib 450 mg reported a dose-limiting toxicity of grade 4 abnormal liver function test and 450 mg was determined as the maximum tolerated dose. The most frequently reported adverse events were febrile neutropenia (78.9%), decreased appetite (42.1%), nausea and rash (36.8% each), and sepsis, fatigue, hypokalemia, stomatitis and epistaxis (26.3% each). Best responses were complete remission (n = 3), complete remission with incomplete blood count recovery (n = 3) and partial remission (n = 1). The median remission duration of the six patients with complete remission or complete remission with incomplete blood count recovery was 85 days (range 56-358). Volasertib exhibited multi-compartmental pharmacokinetic behavior with a fast distribution after the end of infusion followed by slower elimination phases. Volasertib monotherapy was clinically manageable with acceptable adverse events and anti-leukemic activity. PMID:26471242

    Revascularization of an initially non-target site due to its progression as a new culprit lesion has emerged as a new therapeutic target of coronary artery disease (CAD) in the era of drug-eluting stents. Using the Shinken database, a single-hospital-based cohort, we aimed to clarify the incidence and prognostic factors for progression of previously non-significant coronary portions after prior percutaneous coronary intervention (PCI) in Japanese CAD patients. We selected from the Shinken database a single-hospital-based cohort of Japanese patients (n = 15227) who visited the Cardiovascular Institute between 2004 and 2010 to undergo PCI. This study included 1,214 patients (median follow-up period, 1,032 ± 704 days). Additional clinically driven PCI to treat previously non-significant lesions was performed in 152 patients. The cumulative rate of new-lesion PCI was 9.5 % at 1 year, 14.4 % at 3 years, and 17.6 % at 5 years. There was no difference in background clinical characteristics between patients with and without additional PCI. Prevalence of multi-vessel disease (MVD) (82 vs. 57 %, p < 0.001) and obesity (47 vs. 38 %, p = 0.028) were significantly higher and high-density lipoprotein cholesterol (HDL) level (51 ± 15 vs. 47 ± 12 mg/dl, p < 0.001) was significantly lower in patients with additional PCI than those without. Patients using insulin (6 vs. 3 %, p = 0.035) were more common in patients with additional PCI. Multivariate analysis showed that MVD, lower HDL, and insulin use were independent determinants of progression of new culprit coronary lesions. In conclusion, progression of new coronary lesions was common and new-lesion PCI continued to occur beyond 1 year after PCI without attenuation of their annual incidences up to 5 years. Greater coronary artery disease burden, low HDL, and insulin-dependent DM were independent predictors of progression of new culprit coronary lesions. PMID:23807613

    Invasive amebic diseases caused by Entamoeba histolytica are increasing among men who have sex with men and co-infection of ameba and HIV-1 is an emerging problem in developed East Asian countries. To characterize the clinical and epidemiological features of invasive amebiasis in HIV-1 patients, the medical records of 170 co-infected cases were analyzed retrospectively, and E. histolytica genotype was assayed in 14 cases. In this series of HIV-1-infected patients, clinical presentation of invasive amebiasis was similar to that described in the normal host. High fever, leukocytosis and high CRP were associated with extraluminal amebic diseases. Two cases died from amebic colitis (resulting in intestinal perforation in one and gastrointestinal bleeding in one), and three cases died from causes unrelated to amebiasis. Treatment with metronidazole or tinidazole was successful in the other 165 cases. Luminal treatment was provided to 83 patients following metronidazole or tinidazole treatment. However, amebiasis recurred in 6 of these, a frequency similar to that seen in patients who did not receive luminal treatment. Recurrence was more frequent in HCV-antibody positive individuals and those who acquired syphilis during the follow-up period. Various genotypes of E. histolytica were identified in 14 patients but there was no correlation between genotype and clinical features. The outcome of metronidazole and tinidazole treatment of uncomplicated amebiasis was excellent even in HIV-1-infected individuals. Luminal treatment following metronidazole or tinidazole treatment does not reduce recurrence of amebiasis in high risk populations probably due to amebic re-infection. PMID:21931875

    Historically, analysis of patient service time (patient tracking) in ambulatory clinics has been performed manually. A case study of Eye and Ear Clinic in Pittsburgh, PA, revealed that this approach to patient data collection was prone to clerical error and did not satisfy the clinic's information-processing needs. Initial attempts at automation identified the features required of a successful computerized scheduling and patient tracking system. These essential features are being designed into a prototype system using a local area network platform. The software for this system employs bar code technology to log patients' movement. The resultant data permits analysis of clinic operation and rapid response to unforseen events. Patient information is presented in a color-coded format to permit-at-a-glance comprehension of data on multiple patients (up to 76) simultaneously. A scheduling module projects patients' arrival time and ensures availability of critical resources.

    Stickler syndrome is an inherited connective tissue disorder that affects the eyes, cartilage and articular tissues. The phenotypes of Stickler syndrome include congenital high myopia, retinal detachment, premature joint degeneration, hearing impairment and craniofacial anomalies, such as cleft palate and midline facial hypoplasia. The disease is genetically heterogeneous, and the majority of the cases are caused by mutations in the COL2A1 gene. We examined 40 Japanese patients with Stickler syndrome from 23 families to determine whether they had mutations in the COL2A1 gene. This analysis was conducted by examining each patient’s genomic DNA by Sanger sequencing. Five nonsense, 4 splicing and 8 deletion mutations in the COL2A1 gene were identified, accounting for 21 of the 23 families. Different mutations of the COL2A1 gene were associated with similar phenotypes but with different degrees of expressivity. PMID:27408751

    Steroid-resistant nephrotic syndrome (SRNS) represents glomerular disease resulting from a number of different etiologies leading to focal segmental glomerulosclerosis (FSGS). Recently, many genes causing SRNS/FSGS have been identified. These genes encode the proteins associated with the formation and/or maintenance of glomerular filtration barrier. Next-generation sequencing is used to analyze large numbers of genes at lower costs. To identify the genetic background of Japanese patients, we studied 26 disease-causing genes using whole-exome sequencing analysis in 24 patients with SRNS and/or FSGS from 22 different Japanese families. We finally found eight causative gene mutations, four recessive and four dominant gene mutations, including three novel mutations, in six patients from five different families, and one novel predisposing mutation in two patients from two different families. Causative gene mutations have only been identified in ~20% of families and further analysis is necessary to identify the unknown disease-causing gene. Identification of the disease-causing gene would support clinical practices, including the diagnosis, understanding of pathogenesis and treatment. PMID:26467726

    Objectives To evaluate the efficacy and safety of adalimumab+methotrexate (MTX) in Japanese patients with early rheumatoid arthritis (RA) who had not previously received MTX or biologics. Methods This randomised, double-blind, placebo-controlled, multicentre study evaluated adalimumab 40 mg every other week+MTX 6–8 mg every week versus MTX 6–8 mg every week alone for 26 weeks in patients with RA (≤2-year duration). The primary endpoint was inhibition of radiographic progression (change (Δ) from baseline in modified total Sharp score (mTSS)) at week 26. Results A total of 171 patients received adalimumab+MTX (mean dose, 6.2±0.8 mg/week) and 163 patients received MTX alone (mean dose, 6.6±0.6 mg/week, p<0.001). The mean RA duration was 0.3 years and 315 (94.3%) had high disease activity (DAS28>5.1). Adalimumab+MTX significantly inhibited radiographic progression at week 26 versus MTX alone (ΔmTSS, 1.5±6.1 vs 2.4±3.2, respectively; p<0.001). Significantly more patients in the adalimumab+MTX group (62.0%) did not show radiographic progression (ΔmTSS≤0.5) versus the MTX alone group (35.4%; p<0.001). Patients treated with adalimumab+MTX were significantly more likely to achieve American College of Rheumatology responses and achieve clinical remission, using various definitions, at 26 weeks versus MTX alone. Combination therapy was well tolerated, and no new safety signals were observed. Conclusions Adalimumab in combination with low-dose MTX was well tolerated and efficacious in suppressing radiographic progression and improving clinical outcomes in Japanese patients with early RA and high disease activity.

    Background/Aims We investigated writing abilities in patients with the amnestic type of mild cognitive impairment (aMCI) and mild Alzheimer's disease (AD). To examine the earliest changes in writing function, we used writing tests for both words and sentences with different types of Japanese characters (Hiragana, Katakana, and Kanji). Methods A total of 25 aMCI patients, 38 AD patients, and 22 healthy controls performed writing to dictation for Kana and Kanji words, copied Kanji words, and wrote in response to a picture story task. Analysis of variance was used to test the subject group effects on the scores in the above writing tasks. Results For the written Kanji words, the mild AD group performed worse than the aMCI group and the controls, but there was no difference between the aMCI group and the controls. For the picture story writing task, the mild AD and aMCI groups performed worse than the controls, but the difference between the AD and the aMCI groups was not significant. Conclusions The mild AD group showed defects in writing Kanji characters, and the aMCI group showed impairments in narrative writing. Our study suggests that narrative writing, which demands complex integration of multiple cognitive functions, can be used to detect the subtle writing deficits in aMCI patients. PMID:26483830

    The Japanese Urological Association revised the clinical practice guidelines for bladder cancer in April 2015. This was the first update carried out in the 6 years since the development of the initial clinical practice guidelines for bladder cancer in 2009. The descriptive content was revised, and additions were made with a focus on new-found evidence and advances in the latest medical practices, and on the basis of the increasingly aging population observed in the underlying social context in Japan. An algorithm for the treatment of bladder cancer has been presented as a new trial. In the present article, we will introduce the essential contents and clinical questions that address the present revisions. PMID:27374472

    Wolf-Hirschhorn syndrome (WHS) is a contiguous gene deletion syndrome of the distal 4p chromosome, characterized by craniofacial features, growth impairment, intellectual disability, and seizures. Although genotype-phenotype correlation studies have previously been published, several important issues remain to be elucidated including seizure severity. We present detailed clinical and molecular-cytogenetic findings from a microarray and fluorescence in situ hybridization (FISH)-based genotype-phenotype analysis of 22 Japanese WHS patients, the first large non-Western series. 4p deletions were terminal in 20 patients and interstitial in two, with deletion sizes ranging from 2.06 to 29.42 Mb. The new Wolf-Hirschhorn syndrome critical region (WHSCR2) was deleted in all cases, and duplication of other chromosomal regions occurred in four. Complex mosaicism was identified in two cases: two different 4p terminal deletions; a simple 4p terminal deletion and an unbalanced translocation with the same 4p breakpoint. Seizures began in infancy in 33% (2/6) of cases with small (<6 Mb) deletions and in 86% (12/14) of cases with larger deletions (>6 Mb). Status epilepticus occurred in 17% (1/6) with small deletions and in 87% (13/15) with larger deletions. Renal hypoplasia or dysplasia and structural ocular anomalies were more prevalent in those with larger deletions. A new susceptible region for seizure occurrence is suggested between 0.76 and 1.3 Mb from 4 pter, encompassing CTBP1 and CPLX1, and distal to the previously-supposed candidate gene LETM1. The usefulness of bromide therapy for seizures and additional clinical features including hypercholesterolemia are also described. PMID:24357569

    Purpose Virtual glaucoma clinics allow rapid, reliable patient assessment but the service should be acceptable to patients and concordance with treatment needs to be maintained with adequate patient education. This study compares experiences and understanding of patients reviewed via the virtual clinic versus the standard clinic by way of an extended patient satisfaction questionnaire (PSQ). Patients and methods One hundred PSQs were given to consecutive patients attending glaucoma clinics in October 2013. All 135 patients reviewed via the virtual clinic from April 2013 until August 2013 were sent postal PSQs in September 2013. Data were obtained for demographics, understanding of glaucoma, their condition, satisfaction with their experience, and quality of information. Responses were analyzed in conjunction with the clinical records. Results Eighty-five percent of clinic patients and 63% of virtual clinic patients responded to the PSQ. The mean satisfaction score was over 4.3/5 in all areas surveyed. Virtual clinic patients’ understanding of their condition was very good, with 95% correctly identifying their diagnosis as glaucoma, 83% as ocular hypertension and 78% as suspects. There was no evidence to support inferior knowledge or self-perceived understanding compared to standard clinic patients. Follow-up patients knew more about glaucoma than new patients. Over 95% of patients found our information leaflet useful. Forty percent of patients sought additional information but less than 20% used the internet for this. Conclusion A substantial proportion of glaucoma pathway patients may be seen by non-medical staff supervised by glaucoma specialists via virtual clinics. Patients are accepting of this format, reporting high levels of satisfaction and non-inferior knowledge to those seen in standard clinics. PMID:25987832

    Age-associated minor inflammation: inflammageing may explain human ageing mechanism(s). Our previous study reported a significant increase in the serum level of highly sensitive C-reactive protein (hsCRP) with normal ageing and the patients with Werner syndrome (WS). To further study the minor inflammatory condition associated with ageing, another possible ageing biomarker: matrix metalloproteinase-9 (MMP9) was examined in the sera from 217 normal Japanese individuals aged between 1 and 100 years and 41 mutation-proven Japanese WS aged between 32 and 70 years. MMP9 was assayed by ELISA. The serum level of MMP9 was elevated significantly (p < 0.001) with normal ageing from both sexes as hsCRP. In contrast to normal ageing, the serum MMP9 level in WS decreased significantly with calendar age (p < 0.05). The MMP9 level (ng/mL) in WS (147.2 ± 28.5) was not significantly different in comparison with those from age-matched normal adult population aged between 25 and 70 years (109.1 ± 9.4), nor normal elderly population aged between 71 and 100 years (179.9 ± 16.1). Although both normal ageing and WS were associated with minor inflammation, the inflammatory parameters such as serum MMP9 and hsCRP changed differently between normal ageing and WS. The WS-specific chronic inflammation including skin ulcer and diabetes mellitus may contribute the different behavior of both ageing biomarkers from normal ageing. PMID:27195193

    Periodontitis is a chronic inflammatory disease caused by specific bacteria and viruses. Local, systemic, and environmental factors affect the rate of disease progression. Immune responses to bacterial products, and the subsequent production of inflammatory cytokines, are crucial in the destruction of periodontal tissue. MicroRNAs (miRNAs) are a class of small RNAs that control various cell processes by negatively regulating protein-coding genes. In this study, we compared miRNA expression in inflamed and noninflamed gingival tissues from Japanese dental patients. Total RNAs were isolated from inflamed and noninflamed gingival tissues. miRNA expression profiles were examined by an miRNA microarray, and the data were analyzed by GeneSpring GX, Ingenuity Pathways Analysis, and the TargetScan databases. Observed miRNA expression levels in inflamed gingiva were confirmed by real-time PCR. The three most overexpressed (by >2.72-fold) miRNAs were hsa-miR-150, hsa-miR-223, and hsa-miR-200b, and the three most underexpressed (by <0.39-fold) miRNAs were hsa-miR-379, hsa-miR-199a-5p, and hsa-miR-214. In IPA analysis, hsa-miR-150, hsa-miR-223, and hsa-miR-200b were associated with inflammatory disease, organismal injury, abnormalities, urological disease, and cancer. The present findings suggest that miRNAs are associated with chronic periodontitis lesions in Japanese. PMID:25500922

    This randomized, placebo-controlled, double-blind, parallel study assessed the safety, tolerability, pharmacokinetics, and pharmacodynamics of exenatide once weekly (QW) in 30 Japanese patients with type 2 diabetes (T2D) suboptimally controlled by diet and exercise alone or combined with biguanide, sulfonylurea, thiazolidinedione, or combinations of these agents (58.6% male; 58+/-9 years; body mass index 26.3+/-2.9 kg/m(2); hemoglobin A(1c) [HbA(1c)] 7.4+/-0.8%; fasting plasma glucose [FPG] 156.1+/-29.1 mg/dL; duration of T2D 6+/-5 years; means +/- SD). Patients were randomized in a 1:1:1 ratio to subcutaneous placebo QW, exenatide QW 0.8 mg, or exenatide QW 2.0 mg for 10 weeks. All evaluable patients were analyzed (placebo QW, n=10; exenatide QW 0.8 mg, n=10; exenatide QW 2.0 mg, n=9), unless otherwise stated. Steady-state plasma exenatide concentrations were observed by Week 8 of the study. For the evaluable pharmacokinetic population, geometric mean (90% confidence interval) steady-state plasma concentrations (pg/mL) were 81.2 (68.3-96.4) and 344.5 (256.5-462.7) with exenatide QW 0.8 mg (n=8) and exenatide QW 2.0 mg (n=5), respectively. Baseline-to-Week 10 glycemic improvements with placebo QW, exenatide QW 0.8 mg, and exenatide QW 2.0 mg, respectively, were: HbA(1c) (%): -0.4+/-0.3, -1.0+/-0.7, and -1.5+/-0.7; FPG (mg/dL): -20.5+/-20.4, -25.2+/-10.9, and -50.8+/-27.8; and 2-hour postprandial plasma glucose excursions (mg/dL): -8.8+/-26.9, -50.0+/-41.1, and -59.7+/-26.8 (means +/- SD). No serious adverse events (AEs) were reported and no AEs led to study discontinuation in any group. The most frequent AE observed was mild-to-moderate injection site induration. No serious hypoglycemia was reported. Exenatide QW for 10 weeks was well tolerated and improved short-term glycemic control in Japanese patients with suboptimally controlled T2D. PMID:19706990

    Background In this study, we investigated the powerlessness of patients with type 1 diabetes (T1D), and described the structure of powerlessness that these individuals experienced. In order for patients to recover from this state, we recommend that they take steps to regain their power. Methods Fifteen Japanese adults with T1D participated in this study. Data were collected from all subjects between July 2013 and March 2014 via in-depth semi-structured interviews. Qualitative data analysis was conducted according to a grounded theory approach. Finally, the core category was identified, which allowed us to build a new powerlessness structure for T1D. Results The results suggested a core category, ‘Wandering a tangled path,’ comprising four categories, eight subcategories, and twenty-six concepts. These four categories were as follows: ‘being burdened by T1D,’ ‘suffering from insulin-related troubles,’ ‘being unable to cope with difficulties in self-management,’ and ‘facing social prejudice.’ In the state of powerlessness, negative emotional experiences snowballed, with patients feeling more and more depressed until they ultimately reached ‘rock bottom.’ Conclusion We found that as negative emotional experiences related to powerlessness increased, negative feelings intensified until the patients reached rock bottom. Powerlessness is like ‘wandering a tangled path,’ a state in which T1D patients struggle to cope with reality on their own when faced with both internal and external events. ‘Wandering a tangled path’ is at the core of powerlessness. A primary characteristic of the structure of powerlessness is suffering from confusing experiences. To help patients cope with T1D without being crushed by powerlessness, nurses must pay attention to signs of powerlessness. Powerlessness is not just an emotional state, but a combination of feelings, perceptions, and thoughts; therefore, it is important to comprehensively understand patients

    We studied the T cell antigen receptor (TcR) constant beta chain genes on HLA typed Japanese patients with ulcerative colitis (UC). A TcR constant beta EcoRI 6.0-kb fragment was present in all Japanese UC patients (n = 17) but completely absent in the controls (n = 35) (chi2 = 47.6, P less than 0.001). The frequency of HLA-DR2 antigen was significantly higher in UC patients (85% versus 28% in controls, P less than 0.001). Furthermore, HLA-DQw1 antigen was also increased in UC patients (96% versus 60% in controls, P less than 0.001). However, HLA-DR4 antigen was significantly decreased in UC patients (12% versus 37%, P = 0.02). HLA-DR1 antigen was not found in UC patients and was present in only 15% of the controls. These results suggest that TcR beta chain and HLA-DQw1 antigen may be important in the pathogenesis of Japanese UC. Images Fig. 1 PMID:1973647

    Afatinib is a newly approved second-generation epidermal growth factor receptor-tyrosine kinase inhibito r(EGFR-TKI). Afatinib has been shown to prolongthe overall survival of patients with non-small cell lungcancer (NSCLC) with EGFR mutations compared with the standard chemotherapy. However, Grade 3 or 4 toxicities, includingdiarrhea, rash, paronychia, and stomatitis, have been observed more frequently in patients treated with afatinib than in those treated with first-generation EGFR-TKIs. Accordingly, our institution developed an afatinib clinical pathway (the afatinib pathway), which was designed by certified nurses, medical physicians, and certified pharmacists, with the goal of reducing the severity of diarrhea and rash that occur most frequently duringthe 28-day introductory period of afatinib treatment. Between May and October 2014, afatinib was administered accordingto the afatinib pathway to 14 patients with NSCLC and EGFR mutations. Of these patients, only one (7.1%) experienced Grade 3 diarrhea. No other patient experienced Grade 3 or 4 toxicity. The afatinib pathway was effective in reducingthe severities of the diarrhea and rash duringthe 28-day introductory period of the afatinib treatment. Our implementation of the afatinib pathway could be considered the Japanese style of collaborative drugtherapy management (J-CDTM). PMID:26321711

    To investigate antimicrobial susceptibility patterns of various bacterial pathogens isolated from complicated urinary tract infection (UTI) cases, the Japanese Society of Chemotherapy, the Japanese Association of Infectious Disease, and the Japanese Society of Clinical Microbiology conducted the second nationwide surveillance from January to September 2011. With the cooperation of 42 medical institutions throughout Japan, 1036 strains belonging to 8 clinically relevant bacterial species were collected. Among methicillin-resistant Staphylococcus aureus (MRSA) strain, the vancomycin (VCM) MIC for 5.5% (3/55) of the strains was 2 μg/mL. Ampicillin, VCM, and linezolid were relatively active against 209 Enterococcus faecalis strains. The proportion of fluoroquinolone (FQ)-resistant strains was >20%. The MIC90 of FQs against the 382 Escherichia coli strains was 2-64 mg/L and the proportion resistant to FQs was approximately 30%. However, susceptibility of E. coli to sitafloxacin was still high (MIC90 = 2 mg/L). Fifty-eight (15.2%) of 382 E. coli, 6 (4.5%) of 132 Klebsiella pneumoniae, 1 (2.4%) of 41 Klebsiella oxytoca and 4 (6.8%) of 59 Proteus mirabilis strains were suspected of producing extended-spectrum beta-lactamase. Of 93 Pseudomonas aeruginosa strains, the proportions resistant to imipenem, amikacin, and ciprofloxacin were 21.5%, 4.3%, and 20.4%, respectively. Four strains (4.3%) were found to be multidrug-resistant. In complicated UTI cases, all of MRSA and E. faecalis were susceptible to all anti-MRSA agents. Sitafloxacin was active against other FQ-resistant E. coli strains. The isolation of extended-spectrum beta-lactamase-producing and multidrug-resistant strains increased. PMID:26166322

    Objectives To examine the long-term safety of intravenous (IV) abatacept treatment in Japanese patients with rheumatoid arthritis (RA) and an inadequate response to methotrexate (MTX) or other conventional or biologic disease-modifying antirheumatic drugs. Methods This Phase III, open-label, long-term study (NCT00484289) comprised Japanese patients with RA who had completed abatacept Phase I or Phase II studies, and new patients intolerant to MTX. Patients from Phase I and Phase II studies received a weight-tiered dosing equivalent of 10 mg/kg abatacept, with MTX at doses up to 8 mg/week; newly enrolled patients received weight-tiered 10 mg/kg abatacept monotherapy. Safety and efficacy were assessed. Results A total of 217 patients (Phase I, n = 13; Phase II, n = 178; newly enrolled, n = 26) were treated with IV abatacept for a mean of 3 years. Serious adverse events occurred in 67/217 (30.9%) patients. Most adverse events were mild or moderate. For all cohorts combined, American College of Rheumatology 20% response rates ranged from 61.3 to 81.8% for as-observed and last observation carried forward analyses over 192 weeks. Following initial response, clinical and functional outcomes were maintained for up to 3 years. Conclusions In Japanese patients with RA, IV abatacept with and without background MTX showed tolerable safety and sustained efficacy over 3 years. PMID:24754273

    Objective This analysis of the Japanese subpopulation of the PALETTE Phase III, randomized, placebo-controlled study investigated efficacy and safety of pazopanib in patients with metastatic soft tissue sarcoma after failure of standard chemotherapy. Methods Patients were randomly assigned in a 2:1 ratio to receive either pazopanib 800 mg once daily or placebo, with no subsequent cross-over. Primary endpoint was progression-free survival. Secondary endpoints included overall survival and overall response rate. Efficacy analysis was by intent-to-treat. Safety was also investigated. Results Forty-seven patients received either pazopanib (n = 31) or placebo (n = 16). Median progression-free survival was 7.0 weeks (95% confidence interval: 4.0–11.7) for placebo and 24.7 weeks (95% confidence interval: 8.6–28.1) for pazopanib (hazard ratio = 0.41 [95% confidence interval: 0.19–0.90]; P = 0.002). Median overall survival was 14.9 months (95% confidence interval: 6.8—not calculable) for placebo and 15.4 months (95% confidence interval: 7.9–28.8) for pazopanib (hazard ratio = 0.87 [95% confidence interval: 0.41–1.83]; P = 0.687). More patients receiving pazopanib experienced best response of stable disease versus placebo. Adverse events were similar to the global population; those leading to dose reduction were more common and mean daily dose was lower in the Japanese population versus the global population (45 vs. 32% and 624.4 vs. 700.4 mg, respectively). Conclusions The efficacy and safety of pazopanib observed in the Japanese subpopulation of PALETTE were similar to those in the global population. Pazopanib is a new treatment option for Japanese patients with metastatic non-adipocytic soft tissue sarcoma after chemotherapy.

    Prevalence of abdominal migraine (AM) and recurrent abdominal pain (RAP) was evaluated in patients who visited Hikita Pediatric Clinic between May 2010 and April 2015. Patient data were collected prospectively using a questionnaire. Out of a total of 3611 cases, observed prevalence was 2.44% for repeated abdominal pain over a period of ≥3 months, 1.47% for RAP, and 0.19% for AM. Duration of abdominal pain was longer for AM than for non-AM RAP. Certain clinical features were significantly different between AM and non-AM RAP. No correlations were found among age at onset, frequency of attack, and duration of attack for various types of RAP. It was difficult to determine useful diagnostic criteria for distinguishing between AM and non-AM RAP. They did not appear to be separate disease entities but, instead, lie on a disease spectrum. The present prevalence of AM (0.19%) was lower than that in many previous studies from countries other than Japan. PMID:27460403

    Primaquine phosphate has been used to prevent relapse as a radical cure after the acute-phase treatment of vivax and ovale malaria however. Many vivax malaria relapses have been reported following a standard dose of primaquine (15 mg/day for 14 days). A higher dose of primaquine (30 mg/day for 14 days) decreases the relapse rate, and the concomitant risk of gastrointestinal side effects tends to disappear when the drug is administered with food. G6PD deficiency is rare in the Japanese population. Although the relapsed phenomenon is reported globally, the higher dose of primaquine is currently recommended in Japan only for those returning from Southeast Asia or Papua New Guinea. Cases of 18 Japanese, including 13 vivax malaria and 5 ovale malaria, prescribed primaquine at a referral center in Japan, were analyzed retrospectively from 2007-2011. Data on diagnosis, treatment, and outcome were extracted from medical records. Of the 18, 10 with vivax malaria were administered the higher dose of primaquine. We found that only one suffered relapse-a vivax malarial case returning from Brazil and treated with the standard dose of primaquine. No ovale malarial case suffered relapse. None, including the 10 prescribed the higher primaquine dose, experienced any adverse side effects. Based on our findings, we recommend a higher dose of primaquine be used to prevent relapse when treating Japanese suffering from vivax malaria. PMID:23484374

    A c-Met inhibitor tivantinib is a candidate anticancer agent for patients with hepatocellular carcinoma (HCC), and CYP2C19 is the key metabolic enzyme for tivantinib. Previous Japanese phase I studies in patients with solid tumors (except HCC) recommend 360 mg twice daily (BID) and 240 mg BID for CYP2C19 extensive metabolizers (EM) and poor metabolizers (PM), respectively. In this study, Japanese patients with HCC in whom sorafenib treatment has failed were enrolled to evaluate the safety, tolerability and pharmacokinetics of oral tivantinib as a single agent. The dose was escalated separately in EM and PM, from 120 mg BID to 240 mg BID, in both capsule and tablet formulations. A total of 28 patients (EM: 21, PM: 7) received tivantinib. At a dose of 120 mg BID, dose-limiting toxicities (DLT) did not develop in 12 EM (capsule: 6, tablet: 6) and 7 PM (capsule: 4, tablet: 3) during the DLT-observation period (for 29 days after first dosing). At this dose, the pharmacokinetic profiles of tivantinib (AUC0-12 and Cmax ) did not remarkably differ between EM and PM. When treated with 240 mg BID, 5 of 9 EM (capsule: 4 of 6, tablet: 1 of 3) developed neutropenia-related DLT accompanying plasma tivantinib concentration higher than expected from the previous studies. Consequently, PM did not receive 240 mg BID. In conclusion, 120 mg BID of tivantinib is recommended among Japanese patients with HCC regardless of CYP2C19 phenotype. PMID:25711511

    In the FIRST trial (MM-020), lenalidomide plus low-dose dexamethasone (Rd) reduced the risk of disease progression or death compared with combination melphalan-prednisone-thalidomide. As the FIRST trial did not include any Japanese patients, the efficacy and safety of continuous treatment with Rd was evaluated in 26 Japanese patients with newly diagnosed multiple myeloma (NDMM) in a single-arm, multicenter, open-label phase II trial (MM-025). Patients received lenalidomide on days 1-21 of each 28-day cycle, with a starting dose of 25 mg/day (dose adjusted for renal impairment), and 40 mg/day dexamethasone (dose adjusted for age) on days 1, 8, 15 and 22 of each 28-day cycle until disease progression or discontinuation for any reason. In the efficacy evaluable population, overall response rate was 87.5%, including 29.2% of patients who achieved a complete response/very good partial response. Median durations of response, progression-free survival and overall survival have not been reached. The most common grade 3-4 adverse events were neutropenia (23%) and anemia (19%). The efficacy and safety of Rd were consistent with data from larger studies, including the FIRST trial, thereby supporting the use of Rd continuous in Japanese patients with NDMM who are ineligible for stem cell transplantation.

    Background/aim A post-marketing surveillance (PMS) study is being conducted to investigate the safety and effectiveness of the long-term use of dabigatran etexilate (dabigatran) in Japanese patients with nonvalvular atrial fibrillation (NVAF). Results of an interim analysis of this prospective cohort study including patient characteristics and adverse drug reactions (ADRs) collected up to September 17, 2014 are reported here. Methods Patients with NVAF who began to receive dabigatran for the first time from December 2011 to November 2013 were enrolled at 1042 study sites in Japan. Clinical parameters included patient characteristics, dabigatran dose strength, concomitant medications and outcome events. All outcome events were collected as serious and non-serious adverse events (AEs). ADRs were evaluated in this report. Pre-defined safety events of special interest for intensive survey were serious and non-serious outcome events such as myocardial infarction, as well as the total number of hemorrhage and gastrointestinal disorders. Results A total of 6772 patients were registered. The safety analysis set included 6148 patients; mean age was 70.8±9.9 (SD) years: 2323 patients (37.8%) were aged 75 years or older. Males accounted for 66.8% of the patients. Mean CHADS2 score was 1.8±1.3; the CHADS2 score was 0 in 13.6%, 1 in 31.3%, 2 in 25.9%, 3 in 14.9%, and 4 to 6 in 11.1% of the patients. Of the 6148 patients, 1701 patients (27.7%) were switchers from warfarin and 4407 patients (71.7%) were non-switchers (OAC naïve patients). Treatment adherence was assessed for the first 3 months from the start of treatment for this analysis. Total 5656 patients (92.0%) reported taking dabigatran twice daily (bid) every day according to the label recommendation. During the follow up period [mean duration of follow up: 498±259 days (corresponding to 8386 patient-years)], pre-defined safety events of special interest for intensive survey (reported as serious ADRs) were: myocardial

    Mutations in APP, PSEN1 and PSEN2 as the genetic causes of familial Alzheimer's disease (FAD) have been found in various ethnic populations. A substantial number of FAD pedigrees with mutations have been reported in the Japanese population; however, it remains unclear whether the genetic and clinical features of FAD in the Japanese population differ from those in other populations. To address this issue, we conducted a systematic review and meta-analysis of Japanese FAD and frontotemporal dementia with parkinsonism linked to chromosome 17 (FTDP-17) by literature search. Using this analysis, we identified 39 different PSEN1 mutations in 140 patients, 5 APP mutations in 35 patients and 16 MAPT mutations in 84 patients. There was no PSEN2 mutation among Japanese patients. The age at onset in Japanese FAD patients with PSEN1 mutations was significantly younger than that in patients with APP mutations. Kaplan-Meier analysis revealed that patients with MAPT mutations showed a shorter survival than patients with PSEN1 or APP mutations. Patients with mutations in different genes exhibit characteristic clinical presentations, suggesting that mutations in causative genes may modify the clinical presentations. By collecting and cataloging genetic and clinical information on Japanese FAD and FTDP-17, we developed an original database designated as Japanese Familial Alzheimer's Disease Database, which is accessible at http://alzdb.bri.niigata-u.ac.jp/.

    Background The prognosis of Japanese patients with COPD who suffer repeated exacerbations is unclear, although Westerners with such episodes have a poor prognosis. Materials and methods We conducted a 1-year prospective observational trial involving 90 Japanese patients with COPD: 58 nonexacerbators, 12 infrequent exacerbators, and 20 frequent exacerbators classified on the basis of exacerbation frequency (zero, one, and two or more exacerbations/year), respectively, during the previous year were observed prospectively for 1 year. The characteristics of frequent exacerbators, the frequency of exacerbation, and the period until the first event were then compared among the groups. Results A total of 78 patients completed the study. Frequent exacerbators had a significantly higher risk of frequent exacerbation in the following year than the case for nonexacerbators (odds ratio [95% confidence interval] 2.94 [1.21–7.17], P=0.0340), but not in comparison with infrequent exacerbators (1.51 [0.49–4.63], P>0.05). The mean annual frequency of exacerbations in the following year was significantly (P=0.0020) higher in the frequent exacerbators (1.4 exacerbations/year) than in the nonexacerbators (0.4), but not in the infrequent exacerbators (0.9, P>0.05). The mean period until the first exacerbation was significantly shorter in the frequent exacerbators than in the infrequent or nonexacerbators (P=0.0012). Independent risk factors for future frequent exacerbation included the presence of gastroesophageal reflux disease, more severe airflow obstruction, and use of inhaled corticosteroids. Conclusion Our present results indicate that Japanese COPD patients suffering frequent exacerbation have a poor prognosis. The characteristics of Japanese and Western COPD patients suffering frequent exacerbation are similar. PMID:26893552

    Mutations in SLC26A4 cause a broad phenotypic spectrum, from typical Pendred syndrome to nonsyndromic hearing loss associated with enlarged vestibular aqueduct. Identification of these mutations is important for accurate diagnosis, proper medical management and appropriate genetic counseling and requires updated information regarding spectrum, clinical characteristics and genotype–phenotype correlations, based on a large cohort. In 100 patients with bilateral enlarged vestibular aqueduct among 1511 Japanese hearing loss probands registered in our gene bank, goiter data were available for 79, of whom 15 had Pendred syndrome and 64 had nonsyndromic hearing loss. We clarified the mutation spectrum for the SLC26A4 mutations and also summarized hearing levels, progression, fluctuation and existence of genotype–phenotype correlation. SLC26A4 mutations were identified in 82 of the 100 patients (82.0%). Of the Pendred syndrome patients, 93% (14/15) were carriers, as were 77% (49/64) of the nonsyndromic hearing loss patients. Clinical characteristics of patients with SLC26A4 mutations were congenital, fluctuating and progressive hearing loss usually associated with vertigo and/or goiter. We found no genotype–phenotype correlations, indicating that, unlike in the case of GJB2 mutations, the phenotype cannot be predicted from the genotype. Our mutation analysis confirmed the importance of mutations in the SLC26A4 gene among hearing loss patients with enlarged vestibular aqueduct and revealed the mutation spectrum, essential information when performing genetic testing.

    Study Design Cross-sectional. Purpose Clinical outcome study comparing the Copenhagen Neck Functional Disability Scale (CNFDS) and modified Japanese orthopedic association (mJOA) assessment scales in patients with cervical spondylotic myelopathy (CSM). Overview of Literature Comparison of instruments that measure patient-reported outcomes is needed. Methods A cross-sectional analysis was conducted. Ninety five patients with CSM were entered into the study and completed the CNFDS and the mJOA preoperatively and postoperatively. Correlation between the CNFDS and the mJOA was evaluated preoperatively and at the end of follow-up. Responsiveness to change of CNFDS and mJOA was also assessed. Clinical outcomes were also measured with the recovery rate of mJOA score at end of follow-up. Results The mean age of patients was 58.2 (standard deviation, SD=8.7) years. Mean follow-up was 2.1 years (range, 1 to 4 years). The mJOA correlated strongly with the CNFDS score preoperatively and postoperatively (r=–0.81 and –0.82, respectively; p<0.001). The CNFDS and the mJOA were able to detect changes after the surgery (p<0.001). The mean mJOA recovery rate was 51.8% (SD=13.1%). Conclusions Surgery for the treatment of patients with CSM is an efficacious procedure. CNFDS and mJOA scores have a strong correlation in measuring disability among CSM patients. PMID:27340528

    Background The Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Auto-questionnaire (TEMPS-A) is a 110-item questionnaire that assesses five affective temperaments. However, a valid shortened version is desired for large-scale investigations to enhance the compliance of respondents. Methods A confirmatory factor analysis was conducted among 320 psychiatric patients and 61 general adults. The participants completed the Japanese 39-item short version of the TEMPS-A, and a portion of the participants completed the 110-item version. An exploratory factor analysis with the principal factor method and varimax rotation was conducted to identify a more suitable model of the short version of the TEMPS-A. Results The confirmatory factor analysis revealed that the 39-item version exhibited a poor model fit. However, we found that the 18-item version exhibited a firm five-factor structure based on the exploratory factor analysis, and this model exhibited an acceptable model fit. It had good or acceptable internal consistency (Cronbach’s αs: 0.672–0.819). Limitations The majority of the subjects in the present study were patients, and the temperament data may have been affected by psychiatric symptoms. Conclusion A firm five-factor structure was not found in the 39-item short version of the Japanese TEMPS-A. Therefore, an 18-item version was proposed. This new 18-item version of the TEMPS-A might be useful for clinical applications and large-scale investigations. PMID:27601911

    To clarify the status of gene mutation and activation of growth signal in melanoma of Japanese patients in vivo, we analyzed the mutation of BRAF exon 15, NRAS exon 2, and KIT exons 9, 11, 13, 17 and 18 in melanoma cells obtained by laser capture microdissection, and performed direct sequencing in 20 cases of acral lentiginous melanoma (ALM) and 17 cases of superficial spreading melanoma (SSM). In the study of the mutation of BRAF, pyrosequencing was also done. To examine the cell proliferation signaling, immunohistochemistry for phosphorylated extracellular signal-regulated kinase (pERK), phosphorylated AKT (phosphorylated AKT) and c-KIT was done. The mutation of BRAF p.V600E was detected in 13 cases of ALM (65.0%) and 12 cases of SSM (70.6%). No NRAS mutation was found in all cases. The mutation in exons 9, 11, and 18 of KIT was detected in nine cases. The mutation of BRAF and KIT showed no correlation with clinical stage, lymph node metastasis, tumor thickness, ulceration and histology. pERK and pAKT was observed in small population of melanoma cells and there was no correlation with gene mutation. Our results indicate that the mutations of BRAF and KIT exist in Japanese melanoma patients, however, the cell growth signaling may be regulated by not only these mutated genes, but by other unknown regulatory factors, which may affect the prognosis of melanoma.

    Background The incidence of upper gastrointestinal injury by low-dose aspirin (LDA) has increased. Objective We aimed to clarify the risk factors and prevention strategies associated with LDA-induced gastroduodenal ulcer in Japanese patients. Methods A retrospective study involving 284 LDA users who underwent oesophagogastroduodenoscopy between January and December 2010 were included. We investigated the patients’ clinical characteristics and endoscopic findings. Results Of 284 patients, 29 (10.2%) had gastro and/or duodenal ulcers. Male gender, peptic ulcer history, abdominal symptoms, half-dose proton pump inhibitors (PPIs), complete-dose PPIs, and nonsteroidal anti-inflammatory drugs were significantly associated with LDA-induced gastro and/or duodenal ulcers: odds ratio (95% confidence interval) 3.62 (1.06–12.27), 6.60 (1.84–23.62), 3.06 (1.12–8.40), 0.16 (0.03–0.94), 0.07 (0.01–0.61), and 9.68 (1.64–57.18), respectively. PPI significantly reduced gastric ulcers and/or duodenal ulcers (p = 0.03). The modified Lanza score for gastric mucosal lesion in the LDA cessation group was significantly lower than in the LDA noncessation group (0.53 vs. 1.02; p = 0.008). Conclusions Half-dose PPIs as well as complete-dose PPIs were effective for preventing LDA-induced gastric and/or duodenal ulcers. The cessation of LDA before endoscopy may lead to an underestimation of LDA-induced gastric injury. PMID:24917970

    Dying is universal, and death should be a peaceful time. Myriad comfort measures are available in the last weeks before life ends. Discussions about end-of-life issues often suffer from lack of informed opinion. Palliative care experts have identified specific somatic and psychological sources of distress for dying patients and their loved ones. Pain, shortness of breath, nausea and vomiting, and fear of abandonment contribute substantially to both physical and psychological discomfort toward the end of life. Simple, effective methods exist for relieving those symptoms. Knowledge about the natural events associated with dying and an informed approach to medical and psychological interventions contribute to systematic and successful comfort care. We describe the origin of physical and psychological distress at the end of life and provide strategies for alleviating many of the discomforts. PMID:7571591

    The HeLP Patient Legal Clinic has provided free legal advice to public hospital patients with health-related problems since March 2014. This article reports on the findings of a study of the first six months of HeLP's operation. The study adopted qualitative methods informed by grounded theory and sought to understand patient and social worker experiences of HeLP. Interviews were conducted with 13 patients and 10 next of kin. Focus group discussions were carried out with 19 social workers who referred patients to HeLP. Locating the legal service in the hospital's social work department enabled and expedited access to legal advice; a team-based approach to patient problems emerged that enhanced patient outcomes; and provision of legal advice relieved the anxiety experienced by patients, allowing them to focus better on their health concern.

    A 79-year-old male was referred to the Department of Gastroenterology in our hospital due to a large palpable abdominal mass, with the suspicion of a gastrointestinal stromal tumor. An abdominal computed tomographic (CT) scan revealed a huge mass of 270×208×144 mm which occupied the entire pelvic cavity. Since the specimens obtained by an endoscopic ultrasound-guided fine-needle aspiration via lower intestinal tract revealed a Gleason score 4+4 prostate adenocarcinoma, he was then referred to our department. Prostate specific antigen (PSA) was elevated to 3,087 ng/ml, and positron emission tomography-CT revealed right obturator lymph node metastasis and bone metastasis of the left 5th rib. Degarelix was administered as an androgen deprivation therapy, and the PSA level had decreased to 62.4 ng/ml one month later. At the last follow-up, the PSA level was 0.67 ng/ml and the tumorsize had decreased to 88×83×110 mm. Next, we conducted a follow-up survey by mail of 20 reported Japanese cases of a giant prostate carcinoma, and data on 17 cases were available for analysis. In the total of 18 cases, including the present case, with a median follow-up time of 26 months, the 2-year overall survival rate was 85.7% for patients without metastasis, and 65.6% forthose with metastasis.

    Objective Axitinib is a potent and selective second-generation inhibitor of vascular endothelial growth factor receptors 1, 2 and 3. The efficacy and safety of axitinib in Japanese patients with metastatic renal cell carcinoma were evaluated. Methods A subgroup analysis was conducted in Japanese patients enrolled in the randomized Phase III trial of axitinib versus sorafenib after failure of one prior systemic therapy for metastatic renal cell carcinoma. Results Twenty-five (of 361) and 29 (of 362) patients randomized to the axitinib and sorafenib arms, respectively, were Japanese and included in this analysis. Median progression-free survival in Japanese patients was 12.1 months (95% confidence interval 8.6 to not estimable) for axitinib and 4.9 months (95% confidence interval 2.8–6.6) for sorafenib (hazard ratio 0.390; 95% confidence interval 0.130–1.173; stratified one-sided P = 0.0401). The objective response rate was 52.0% for axitinib and 3.4% for sorafenib (P = 0.0001). The common all-causality adverse events (all grades) in Japanese patients were dysphonia (68%), hypertension (64%), hand–foot syndrome (64%) and diarrhea (56%) for axitinib, and hand–foot syndrome (86%), hypertension (62%) and diarrhea (52%) for sorafenib. The safety profiles of axitinib and sorafenib in Japanese patients were generally similar to those observed in the overall population, with the exceptions of higher incidences of hypertension, dysphonia, hand–foot syndrome, hypothyroidism and stomatitis. Conclusions Axitinib is efficacious and well tolerated in Japanese patients with previously treated metastatic renal cell carcinoma, consistent with the results in the overall population, providing a new targeted therapy for these Japanese patients.

    Background This phase I study evaluated the safety and tolerability, pharmacokinetics and pharmacodynamics, immunogenicity, and antitumor activity of pembrolizumab in Japanese patients with advanced solid tumors. Methods Following an initial dose and a 28-day rest (cycle 1), pembrolizumab was administered as an intravenous infusion at escalating doses (2 or 10 mg/kg) every 2 weeks (Q2W) until disease progression or unacceptable toxicity. Adverse events (AEs) were assessed using CTCAE v4.0, and tumor response was assessed using both RECIST v1.1 and immune-related response criteria (irRC). Full pharmacokinetic sampling was performed during cycle 1. Results Three patients received pembrolizumab at 2.0 mg/kg and seven at 10 mg/kg. No dose-limiting toxicities were observed during cycle 1. Eighty percent of patients experienced drug-related AEs (mostly grade 1 or 2); the most common drug-related AEs were nausea, malaise, pyrexia, and aspartate aminotransferase/alanine transaminase (AST/ALT) elevations (n = 2 each). No drug-related grade 4 or 5 AEs occurred. Immune-related AEs comprised grade 3 ALT elevation (n = 1), grade 3 AST elevation (n = 1), grade 1 pneumonitis (n = 1), and grade 1 thyroid-stimulating hormone elevation (n = 1). The safety and pharmacokinetic profiles of Japanese patients were similar to those previously reported for Caucasian patients. A partial tumor response was observed in one patient with non-small-cell lung cancer (NSCLC) and in one patient with melanoma. Conclusions Pembrolizumab at both 2 and 10 mg/kg Q2W was well tolerated in Japanese patients with advanced solid tumors and showed encouraging anti-tumor activity against melanoma and NSCLC.

    Introduction The objective of this study was to identify the patterns of dental variables of adolescent Japanese-Brazilian descents with normal occlusion, and also to compare them with a similar Caucasian and Mongoloid sample. Methods Lateral cephalometric radiographs were used to compare the groups: Caucasian (n = 40), Japanese-Brazilian (n = 32) and Mongoloid (n = 33). The statistical tests used were one-way ANOVA and ANCOVA. The cephalometric measurements used followed the analyses of Steiner, Tweed and McNamara Jr. Results Statistical differences (P < 0.05) indicated a smaller interincisal angle and overbite for the Japanese-Brazilian sample, when compared to the Caucasian sample, although with similar values to the Mongoloid group. Conclusion The dental patterns found for the Japanese-Brazilian descents were, in general, more similar to those of the Mongoloid sample. PMID:25279521

    Psoriasis has been shown to accompany systemic inflammation. We aimed to examine serum C-reactive protein (CRP) levels in Japanese psoriatic patients, and to elucidate their long-term as well as short-term changes by treatment with different biologics. A retrospective study was conducted in those who initiated and successfully continued the treatment for up to 24 months with either infliximab, adalimumab or ustekinumab, at the psoriasis special clinic of Jikei University School of Medicine. A total of 212 patients were included, 171 with plaque-type psoriasis (PsV) and 41 with psoriatic arthritis (PsA). A statistically significant elevation of CRP values was found in the group with a Psoriasis Area and Severity Index (PASI) of 12 or more compared with the PASI of less than 12 for both PsV and PsA. The CRP-positive patients had a higher proportion of PsA compared with the CRP-negative patients, and they had significantly higher PASI scores. Serum CRP values declined as early as at 3 months after systemic treatment with biologics. Tumor necrosis factor (TNF)-α antagonists did lead to a notable and sustained CRP decline up to 24 months. Infliximab showed rapid decline, while CRP decline by adalimumab treatment was time-dependent. The interleukin-12/23 p40 antagonist, ustekinumab, appeared to be less potent than TNF-α antagonists in stabilizing CRP values at low levels despite good control of cutaneous lesions. In conclusion, serum CRP levels can be used to assess disease severity in Japanese psoriatic patients as a marker of systemic inflammation. TNF-α antagonists may be more beneficial than ustekinumab in this regard. PMID:26704718

    Medulloblastoma is the most common solid malignancy and cause of oncologic death among children. Recent advances in genomic analysis obtained through international large-scale collaborations, Medulloblastoma Advanced Genomics International Consortium(MAGIC), have revealed that medulloblastomas can be classified into at least four distinct subgroups depending on their molecular expression profiles. These studies showed that the prognosis, age distributions, and molecular mechanisms of these subgroups of medulloblastomas completely differ from each other. Here we report the first analysis of molecular subgroups of medulloblastoma in Japanese patients(Shizuoka cohort). Molecular subgroups were predicted for 18 medulloblastomas;and age distributions, radiographic features, and histological characteristics were analyzed. It was predicted that 11% of the medulloblastomas were of the WNT type, 50% of the SHH type, 6% of the group 3 type, and 33% of the group 4 type. The percentage of group 3 type medulloblastomas was smaller than in the MAGIC study, while the percentage of the SHH type was larger. However, age distribution, recurrence-free survival, and overall survival for each group were quite similar to the MAGIC study. In addition, in an imaging study, 78% of patients with medulloblastomas of the SHH type presented tumors in the cerebellar hemispheres. The classical pathohistological hallmarks that may predict medulloblastoma prognosis were mainly seen in tumors of the SHH type. Molecular subgrouping of medulloblastomas could be important in the future, not only for prediction of prognosis, but also for decision making regarding the use of future new treatments such as molecular targeting therapy. The establishment of a public molecular analysis system of medulloblastomas in Japan is greatly desired, and it is currently under development;this database will help establish the molecular diagnosis of medulloblastomas in Japan.

    The impact of atopic dermatitis on patients' quality of life was measured using the Japanese version of Skindex-16 in a cross-sectional and longitudinal questionnaire study. One hundred sixty-two adult patients completed Skindex-16 and were followed-up with a standard medical therapy. Three to six months after the initial testing, 135 (83.3%) of the patients again completed Skindex-16 and also answered a general question about whether their skin condition had improved, remained the same, or become worse. The scores of Skindex-16 of 162 patients with atopic dermatitis were significantly higher than those of patients with isolated lesions, particularly in the Symptoms and Emotions scales. Patients with severe atopic dermatitis showed significantly higher scores in the three scales (Symptoms, Emotions, and Functioning), and there was a significant positive correlation between the severity and the 3-scale scores. After the follow-up period, 78 of 135 patients (57.8%) reported that their skin condition had improved. Forty-six patients (34.1%) reported that their skin condition had remained the same, and 11 (8.1%) became worse. Among the patients who said their dermatitis had improved, the scores of Skindex-16 significantly decreased. On the other hand, patients who reported their dermatitis worse showed an increase in the scores. These findings suggest that Skindex-16 responsively measures the disease severity and clinical change in the estimation of the effects of atopic dermatitis on patients' quality of life. This practical and sensitive, skin-disease specific, quality-of-life instrument is valuable for assessing patients' outcomes, especially their response to therapy, and is useful to understanding and improving the quality of life of patients suffering with atopic dermatitis.

    Objective This study investigated the clinical efficacy of a combination therapy of levocetirizine (LCTZ) and fluticasone furoate nasal spray (FFNS), compared with LCTZ monotherapy, for the suppression of seasonal allergic rhinitis (SAR) symptoms induced in an artificial exposure chamber. Methods This study was a single-center, placebo-controlled, randomized, 3-way cross-over comparative study performed in 42 Japanese cedar pollinosis patients. These subjects received (1) LCTZ plus FFNS (combination group), (2) LCTZ plus FFNS placebo (monotherapy group), or (3) LCTZ placebo plus FFNS placebo (placebo group) once on the night prior to exposure, with a 1-week washout period between exposures. Nasal (sneezing, rhinorrhea, nasal congestion, and itchy nose) and ocular (eye itching and tearing) symptoms were recorded every 15 min, and the number of sneezes, nose blowing events, and the amount of nasal secretions were measured during exposure. The primary end-point was the cumulative incidence of SAR symptoms during exposure and the ‘ime to occurrence of symptoms’. The secondary end-points were the total nasal symptom score, the ocular symptom score, the amount of nasal discharge, and the number of sneezes and nose blowing events. Results At all the measurement points, the lowest cumulative incidences for the nasal symptoms were observed in the combination group, followed by the monotherapy and placebo groups. All the subjects in the placebo group developed nasal symptoms within 2 h after pollen exposure, while three and eight subjects in the monotherapy and combination groups, respectively, did not develop any nasal symptoms during exposure. In addition, combination therapy delayed the onset of symptoms. Conclusions The results demonstrated that combination therapy with FFNS and LCTZ significantly suppressed the induced SAR symptoms and delayed the onset of symptoms compared with LCTZ monotherapy and placebo.

    Abdominal obesity, rather than total amount of fat, is linked to obesity-related disorders. Visceral adiposity is an important component of obesity-related disorders in Japanese individuals with a mild degree of adiposity compared with Western subjects. In 1983, our group reported techniques for body fat analysis using computed tomography (CT) and established the concept of visceral fat obesity in which intra-abdominal fat accumulation is an important factor in the development of obesity-related complications, such as diabetes, lipid disorders, hypertension and atherosclerosis. Our group also established ideal imaging conditions for determining abdominal fat area at the umbilical level CT scan. Visceral fat area (VFA) measured in a single slice at L4 level correlated significantly with the total abdominal visceral fat volume measured on multislice CT scan. In a large-scale study of a Japanese population, the mean number of obesity-related cardiovascular risk factors (hypertension, low high-density lipoprotein cholesterolemia and/or hypertriglyceridemia, and hyperglycemia) was greater than 1.0 at 100 cm2 of VFA, irrespective of gender, age and body mass index. Our group also demonstrated that reduction of visceral fat accumulation subsequent to voluntary lifestyle modification, “Hokenshido”, correlated with a decrease in the number of obesity-related cardiovascular risk factors. It is important to select the most appropriate subjects from the general population (e.g., non-obese subjects with a cluster of risk factors for the metabolic syndrome) that are most suitable for body weight reduction, with the goal of preventing atherosclerotic cardiovascular diseases.

    Type 2 diabetes mellitus (T2DM) is a complex heterogeneous group of metabolic disorders including hyperglycemia and impaired insulin action and/or insulin secretion. Obesity T2DM has become a serious problem in Japan as in Western countries, with over-eating and physical inactivity. Obese Asians have mild degree of adiposity, compared with Western subjects. Unlike total body fat, body fat distribution, especially excess accumulation of visceral fat, correlates with various diabetogenic, atherogenic, prothrombotic and proinflammatory metabolic abnormalities, which increase the risk of atherosclerotic cardiovascular disease (ACVD). Obese patients with T2DM have poor glycemic control with disordered eating behaviors, and complications of hypertension and dyslipidemia, leading to ACVD. The major therapies in obese T2DM, hyperinsulinemia and low insulin sensitivity, available for weight loss, especially visceral fat reduction, include caloric restriction, physical activity and behavior modification. On the other hand, the major therapies in non-obese T2DM with insufficient insulin secretion, are insulin-secretory agents and injectable insulin. For clinically meaningful prevention/reduction in the rate of future ACVD in T2DM, it may be important to stratify T2DM subjects into those with and without visceral obesity and design specific management protocols for each group.

    The nucleotide sequence of the Japanese type of hepatitis C virus (HCV-J) genome, consisting of 9413 nucleotides, was determined by analyses of cDNA clones from plasma specimens from Japanese patients with chronic hepatitis. HCV-J genome contains a long open reading frame that can encode a sequence of 3010 amino acid residues. Comparison of HCV-J with the American isolate of HCV showed 22.6% difference in nucleotide sequence and 15.1% difference in amino acid sequence. Thus HCV-J and the American isolate of HCV are probably different subtypes of HCV. The relationship of HCV-J with other animal RNA virus families and the putative organization of the HCV-J genome are discussed.

    We conducted a phase 1/2 study of single-agent carfilzomib in Japanese patients with relapsed/refractory multiple myeloma. Safety, pharmacokinetics and pharmacodynamics of carfilzomib were examined in phase 1. The primary endpoint in phase 2 was the overall response rate (ORR). Carfilzomib was administered in a twice-weekly, consecutive-day dosing schedule. In Phase 1, doses of 15 or 20 mg/m(2) were administered on this schedule or 20 mg/m(2) on Days 1 and 2 of Cycle 1 and then 27 mg/m(2) in the 20/27 mg/m(2) cohort. Patients had a median of five prior therapies, including bortezomib and an immunomodulatory agent. The dose level did not reach the maximum tolerated dose. The most common adverse events were haematological. Notably, carfilzomib either induced new hypertension (n = 4) or aggravated previously existing hypertension (n = 6) in 10 of 50 patients. Four of the eight patients who previously experienced peripheral neuropathy (PN) experienced a recurrence with carfilzomib use, but no new cases of PN occurred. The ORR of the 20/27 mg/m(2) 40 patient cohort was similar to that in the pivotal US study. The dose was efficacious and tolerable in heavily pre-treated Japanese patients; however, meticulous control of hypertension may be necessary for further carfilzomib use. PMID:26732066

    The different patterns of gastric cancer in the Far East and West have evolved to the extent that it has been suggested that the disease in Japan is biologically less aggressive than in the West. We studied paraffin-embedded, formalin-fixed tissue blocks from Japanese patients and American patients of European descent who had undergone gastrectomy for gastric cancer not involving the gastroesophageal junction. Specimens were staged (T stage), graded (Lauren classification), and biomarker expression (epithelial cadherin [E-cadherin], c-erbB2, Ki67, and p53) was quantified using immunohistochemistry without knowledge of the country of origin. E-cadherin was expressed in 49 per cent of malignant cells from Japanese specimens compared with 27 per cent of malignant cells from American specimens (P = 0.04). The expression of E-cadherin on diffuse cancers from the two countries was similar (34.4 in Japanese vs 41.5 in American, P = 0.92). E-cadherin expression, however, was significantly higher among intestinal cancers from the two countries: 56.3 per cent of cells from intestinal or mixed cancers from Japan (n = 32) expressed E-cadherin compared with 22.2 per cent of American specimens (n = 12; P = 0.008).-c-erbB2 was expressed on a higher proportion of malignant cells from American specimens (30% vs 22%; P = 0.20). E-cadherin expression, a favorable prognostic factor, is more common in Japanese intestinal-type gastric cancer not involving the gastroesophageal junction. If the biology of gastric cancer in the Far East is less aggressive than that in the United States, it is likely that treatments need to be individualized. PMID:16676859

    We report a male infant with FATCO syndrome, an acronym for fibular aplasia, tibial campomelia, and oligosyndactyly. Courtens et al. reported an infant with oligosyndactyly of the left hand, complete absence of the right fibula, bowing of the right tibia, and absence of the right fifth metatarsal and phalanges. They noted 5 patients with similar clinical features, and proposed the FATCO syndrome. Our patient had a left-sided cleft lip, cleft palate, oligosyndactyly of the right hand and bilateral feet, and bilateral anterior bowing of the limbs associated with overlying skin dimpling. Radiographs showed a short angulated tibia with left fibular aplasia and right fibular hypoplasia. We consider our case the 6th patient with FATCO syndrome, and the cleft lip and palate, not reported in the previous 5 patients, may allow us to further understand the development of the extremities and facies.

    Background: The Combined Quality Care Anterior Cruciate Ligament registry provides data for clinical research regarding primary anterior cruciate ligament (ACL) surgery. Purpose: To explore the data with regard to the clinical outcomes between sexes after ACL reconstruction in a Dutch population. Study Design: Cohort study; Level of evidence, 3. Methods: Data involving patients diagnosed with an ACL tear and eligible for surgery were recorded. Isokinetic muscle strength, functional muscle performance, and anterior-posterior translation of the knee joint were documented preoperatively and at 3, 6, 9, and 12 months postoperatively. Patients completed the Knee Injury and Osteoarthritis Outcome Score (KOOS), Lysholm, and Tegner rating scales during each examination using a web-based questionnaire. Results: Approximately 90% of ACL injuries occurred during sport activities. The mean (SD) age at surgery was 28 (11) years for both men and women, and the majority of patients were treated with hamstring tendon autografts (94%). Four percent received bone–patellar tendon–bone autografts, and 2% of the patients received other grafts. Preoperatively, the KOOS, Lysholm, and Tegner scores were significantly higher in males. Twelve months postoperatively, both sexes showed comparable isokinetic strength (P = .336), knee laxity (P = .680), and hop test for distance (P = .122) when comparing the injured with the uninjured side. Self-reported knee function was comparable between sexes as assessed by the KOOS (P = .202), Lysholm (P = .872), and Tegner (P = .767) questionnaires during the 12-month follow-up. Conclusion: One year after ACL surgery, all patients had improved greatly, showing only minor differences between sexes. The male group showed slightly better results when evaluating self-reported knee questionnaires. Comparable outcomes and knee function between sexes can therefore be presumed with patients who are treated with hamstring tendon autografts in a Dutch

    Filovirus infection presents many unique challenges to patient management. Currently no approved treatments are available, and the recommendations for supportive care are not evidence based. The austere clinical settings in which patients often present and the sporadic and at times explosive nature of filovirus outbreaks have effectively limited the information available to evaluate potential management strategies. This review will summarize the management approaches used in filovirus outbreaks and provide recommendations for collecting the information necessary for evaluating and potentially improving patient outcomes in the future.

    Treatment of HCV genotype 1b (GT1b)-infected Japanese patients with paritaprevir (NS3/4A inhibitor boosted with ritonavir) and ombitasvir (NS5A inhibitor) in studies M12-536 and GIFT-I demonstrated high sustained virologic response (SVR) rates. The virologic failure rate was 3% (13/436) across the two studies. Analyses were conducted to evaluate the impact of baseline resistance-associated variants (RAVs) on treatment outcome and the emergence and persistence of RAVs in patients experiencing virologic failure. Baseline paritaprevir resistance-conferring variants in NS3 were infrequent, while Y93H in NS5A was the most prevalent ombitasvir resistance-conferring variant at baseline. A comparison of baseline prevalence of polymorphisms in Japanese and western patients showed that Q80L and S122G in NS3 and L28M, R30Q, and Y93H in NS5A were significantly more prevalent in Japanese patients. In the GIFT-I study, the prevalence of Y93H in NS5A varied between 13% and 21% depending on the deep-sequencing detection threshold. Among patients with Y93H comprising <1%, 1 to 40%, or >40% of their preexisting viral population, the 24-week SVR (SVR24) rates were >99% (276/277), 93% (38/41), and 76% (25/33), respectively, indicating that the prevalence of Y93H within a patient's viral population is a good predictor of treatment response. The predominant RAVs at the time of virologic failure were D168A/V in NS3 and Y93H alone or in combination with other variants in NS5A. While levels of NS3 RAVs declined over time, NS5A RAVs persisted through posttreatment week 48. Results from these analyses are informative in understanding the resistance profile of an ombitasvir- plus paritaprevir/ritonavir-based regimen in Japanese GT1b-infected patients. PMID:26643326

    Pneumococcal Molecular Epidemiology Network (PMEN) clones are representatives of worldwide-spreading pathogens. DiversiLab system, a repetitive PCR system, has been proposed as a less labor-and time-intensive genotyping platform alternative to conventional methods. However, the utility and analysis parameters of DiversiLab for identifying worldwide lineages was not established. To evaluate and optimize the performance of DiversiLab for identifying worldwide pneumococcal lineages, we examined 245 consecutive isolates of clinical Streptococcus pneumoniae from all age-group patients at a teaching hospital in Japan. The capsular swelling reaction of all isolates yielded 24 different serotypes. Intensive visual observation (VO) of DiversiLab band pattern difference divided all isolates into 73 clusters. Multilocus sequence typing (MLST) of representative 73 isolates from each VO cluster yielded 51 different STs. Among them, PMEN-related lineages accounted for 63% (46/73). Although the serotype of PMEN-related isolates was identical to that of the original PMEN clone in 70% (32/46), CC156-related PMEN lineages, namely Greece(6B)-22 and Colombia(23F)-26, harbored various capsular types discordant to the original PMEN clones. Regarding automated analysis, genotyping by extended Jaccard (XJ) with a 75% similarity index cutoff (SIC) showed the highest correlation with serotyping (adjusted Rand's coefficient, 0.528). Elevating the SIC for XJ to 85% increased the discriminatory power sufficient for distinguishing two major PMEN-related isolates of Taiwan(19F)-14 and Netherlands(3)-31. These results demonstrated a potential utility of DiversiLab for identifying worldwide lineage of pneumococcus. An optimized parameters of automated analysis should be useful especially for comparison for reference strains by "identification" function of DiversiLab. PMID:27107736

    We studied the reading performance of a Japanese-speaking patient, TI, with bilateral but asymmetrical (left more than right) temporal-lobe atrophy, severe anomia, and poor word comprehension. Most Japanese kanji characters correspond to several different legitimate pronunciations in different contexts, with varying degrees of correspondence consistency. TI made many errors in reading aloud words that violate statistically typical character-sound correspondences, especially for less common words, but had relatively preserved ability to read aloud strings in which the assignment of the typical pronunciation for each component character yields the correct pronunciation for the whole word. The degree of consistency of character-sound correspondences affected his performance on both words and nonwords in a graded manner. One interpretation is that TI's surface dyslexic reading reflects intact direct computation of phonology from orthography, but without the additional constraint from word meaning that is, in this framework, considered critical for correct pronunciation of lower-frequency words with atypical character-sound correspondences. Another interpretation is that TI's performance reflects partially damaged lexical knowledge of whole-word orthography and phonology, coupled with spared sublexcal knowledge of character-sound correspondence rules. Whichever of these interpretations is preferred, this study offers the most detailed information yet available on the characteristics of surface dyslexia in Japanese. PMID:12887989

    Raltegravir (RAL), an HIV integrase inhibitor, is metabolized mainly by UDP-glucuronosyltransferase 1A1 (UGT1A1). Polymorphisms in UGT1A1 may cause alterations in the pharmacodynamics of RAL, which is taken twice daily with no dietary restrictions. We compared the effect of two polymorphic alleles in this gene, UGT1A1*6 and UGT1A1*28 on plasma RAL concentrations in Japanese HIV-1-infected patients. Of 114 Japanese HIV-1-infected patients who received RAL, the frequencies of UGT1A1*6 and UGT1A1*28 were 18% and 13%, respectively. The percentage of homozygotes for UGT1A1*6 and UGT1A1*28 was 6% and 4%, respectively, the percentage of compound heterozygotes for UGT1A1*6 and UGT1A1*28 was 2%, and that of heterozygotes for UGT1A1*6 and UGT1A1*28 was 22% and 17%, respectively. RAL plasma trough concentrations were compared for each polymorphism. Significantly higher levels of RAL were observed with patients who were homozygous for UGT1A1*6 (median: 1.0 μg/mL) than for the normal allele (median: 0.11 μg/mL; p = 0.021). Multivariate logistic regression analysis showed that the presence of one or two alleles of UGT1A1*6 or two alleles of UGT1A1*28 were independent factors associated with high RAL plasma trough concentrations (≥ 0.17 μg/mL). These results indicated that UGT1A1*6 and UGT1A1*28 are both factors influencing the RAL plasma trough concentrations in Japanese HIV-1-infected patients. PMID:26233886

    The efficacy of thiopurines, including azathioprine (AZA) and 6-mercaptopurine (6MP), has been demonstrated for the treatment of inflammatory bowel disease (IBD). The most common and serious adverse event of treatment with thiopurines altered by doctors is leukopenia. Hair loss is also a serious event that could be a critical reason for patients to decline thiopurine treatment. Thiopurine-induced severe hair loss causes cosmetic problems, and it takes a long time to recover. In a recent study, NUDT15 R139C was strongly associated with thiopurine-induced leukopenia in Korean and Caucasian populations. In this study, we performed an association study to investigate and replicate the association of R139C with adverse events of thiopurines in Japanese patients. A total of 142 Japanese patients with IBD, with histories of thiopurine treatment, were examined. NUDT15 R139C was genotyped using a custom TaqMan genotyping assay. Adverse events including leukopenia were reviewed from medical records. The 6MP dose was adjusted to AZA equivalents by multiplying with 2 as a thiopurine dose. Five patients developed severe hair loss and all of them were risk homozygous (T/T) for R139C. No early severe hair loss was observed in patients with the C/T or C/C genotype (P=3.82 × 10(-16), odds ratio=212). The association of R139C with early (<8 weeks) leukopenia (white blood cells<3000 mm(-3)), which was previously reported in Korean patients, was replicated in our Japanese IBD cohort (P=1.92 × 10(-16), odds ratio=28.4). However, we could not confirm the association with late leukopenia in the Japanese subjects. Patients with the C/T genotype discontinued treatment or required thiopurine dose reduction significantly earlier than patients with the C/C genotype (P=1.45 × 10(-4)); however, on manipulating the doses, there was no significant difference in the thiopurine continuation rates between the groups. In the maintenance period, the frequencies of 6MP usage were higher, and the

    Objective The aim of this study was to evaluate the effectiveness of clinical criteria for the diagnosis of hyposalivation in hospitalized patients. Material and Methods A clinical study was carried out on 145 subjects (48 males; 97 females; aged 20 to 90 years). Each subject was clinically examined, in the morning and in the afternoon, along 1 day. A focused anamnesis allowed identifying symptoms of hyposalivation, like xerostomia complaints (considered as a reference symptom), chewing difficulty, dysphagia and increased frequency of liquid intake. Afterwards, dryness of the mucosa of the cheecks and floor of the mouth, as well as salivary secretion during parotid gland stimulation were assessed during oral examination. Results Results obtained with Chi-square tests showed that 71 patients (48.9%) presented xerostomia complaints, with a significant correlation with all hyposalivation symptoms (p<0.05). Furthermore, xerostomia was also significantly correlated with all data obtained during oral examination in both periods of evaluation (p<0.05). Conclusion Clinical diagnosis of hyposalivation in hospitalized patients is feasible and can provide an immediate and appropriate therapy avoiding further problems and improving their quality of life.

    Endovenous laser ablation (EVLA), which is a relatively new therapeutic option for saphenous varicose veins of the legs, is less invasive than conventional stripping surgery with ligation. In this study, we evaluated the safety and effectiveness of EVLA combined with ligation for severe saphenous varicose veins that were graded as ≥ C4 by the CEAP classification. We treated 119 Japanese patients (141 limbs) between July 2005 and December 2007 utilizing a 1320-nm Nd:YAG laser. The obliteration rate of the treated veins was found to be 100% over the entire follow-up period (2.5 years). Consistent with this finding, all of the patients exhibited improved skin lesions (ie, skin pigmentation and ulceration). No major complications, including deep vein thrombosis (DVT) and nerve injury, were observed. A questionnaire survey with a reasonable response rate (66.4%) demonstrated that subjective symptoms and minor complications that were initially observed after EVLA, such as mild pain, numbness, indurations, and localized hot flashes, were remarkably improved by the end of the follow-up period. Furthermore, high levels of patient satisfaction were noted. Thus, EVLA combined with ligation constituted a safe and effective strategy for treating severe saphenous varicose veins in Japanese patients. PMID:26742879

    Objective Late toxicity after concurrent chemoradiotherapy (CCRT), such as dysphagia, in patients with squamous cell carcinoma of the head and neck has received a good deal of attention recently. The gastrostomy tube (G-tube) dependence rate 1 year after CCRT was reported to be 16.7–42.9% in Western countries. We evaluated swallowing outcomes after CCRT in patients with hypopharyngeal cancer (HPC) treated in our hospital and compared them with previous reports. Methods We reviewed 96 consecutive patients with a HPC treated by radiotherapy with intravenous or intra-arterial chemotherapy between 2006 and 2013 at Hokkaido University Hospital, Sapporo, Japan. Results At 1 month after CCRT, 13 patients (13.7%) used a G-tube, whereas 5/91 (5.5%) and 4/81 (4.9%) used a G-tube at 3 and 6 months, respectively. Two patients used a G-tube at 12 and 24 months after CCRT (G-tube use rate: 2.8% at 12 months, and 3.2% at 24 months). The variables female, posterior wall primary, stage IV, ECOG performance status of 2, and smoking status were significantly associated with G-tube use at 12 months after CCRT, whereas the route of cisplatin administration was not related to G-tube use (p = 0.303). Conclusions The G-tube use rate up to 1year could be lower in Japanese patients than in Western patients according to previous reports. In particular, Japanese patients resume oral intake sooner than Western patients. Further study of the incidence of dysphagia after CCRT by ethnicity is required to clarify the differences in dysphagia after CCRT. PMID:27556279

All patients received a mixture of HJG or GJG for 12 weeks in addition to α1-blockers or antimuscarinic drugs as add-on therapy. International Prostate Symptom Score, International Prostate Symptom Score–Quality of Life, Benign Prostatic Hyperplasia Impact Index, and the number of nocturnal voids were statistically much improved. However, there was no change in maximal urinary flow rate and post-void residual urine. Urinary 8-hydroxy-2-deoxyguanosine was statistically greatly improved from baseline after treatment in the HJG group compared to the GJG group. Adverse reactions were observed in 8.3% of patients, but all reactions were mild. Both HJG and GJG mixtures can serve as safe and effective potential therapeutic alternatives in patients with LUTS and cold sensitivity unresponsive to α1-blockers or antimuscarinic drugs. Additionally, HJG mixture was found to have anti-oxidative activity, and therefore further long-term clinical investigations are needed to examine its anti-aging effects in addition to its effect on urinary symptoms.

    Background and Objective The STarT Back Tool uses prognostic indicators to classify patients with low back pain into three risk groups to guide early secondary prevention in primary care. The present study aimed to evaluate the psychometric properties of the Japanese version of the tool (STarT-J). Methods An online survey was conducted among Japanese patients with low back pain aged 20–64 years. Reliability was assessed by examining the internal consistency of the overall and psychosocial subscales using Cronbach’s alpha coefficients. Spearman’s correlation coefficients were used to evaluate the concurrent validity between the STarT-J total score/psychosocial subscore and standard reference questionnaires. Discriminant validity was evaluated by calculating the area under the curves (AUCs) for the total and psychosocial subscale scores against standard reference cases. Known-groups validity was assessed by examining the relationship between low back pain-related disability and STarT-J scores. Results The analysis included data for 2000 Japanese patients with low back pain; the mean (standard deviation [SD]) age was 47.7 (9.3) years, and 54.1% were male. The mean (SD) STarT-J score was 2.2 (2.1). The Cronbach’s alpha coefficient was 0.75 for the overall scale and 0.66 for the psychosocial subscale. Spearman’s correlation coefficients ranged from 0.30 to 0.59, demonstrating moderate to strong concurrent validity. The AUCs for the total score ranged from 0.65 to 0.83, mostly demonstrating acceptable discriminative ability. For known-groups validity, participants with more somatic symptoms had higher total scores. Those in higher STarT-J risk groups had experienced more low back pain-related absences. Conclusions The overall STarT-J scale was internally consistent and had acceptable concurrent, discriminant, and known-groups validity. The STarT-J can be used with Japanese patients with low back pain. PMID:27002823

    The analysis was designed to compare the pharmacokinetics (PK) of sepantronium between US and Japanese patient populations using data obtained from two phase 1 studies being conducted in a similar design, one conducted in the USA and the other in Japan. Patients with a confirmed advanced solid tumor or non-Hodgkin lymphoma (NHL) (US only) that were refractory to standard therapy or for which no standard therapy was available participated in these studies. Sepantronium bromide was administered as a continuous intravenous infusion for 168 h (7 days) every 21 days. During the first two treatment cycles, serial blood and urine samples were collected for up to 48 h after termination of sepantronium bromide infusion. Forty-one subjects in the US study (including five patients with NHL) and 33 patients in the Japanese study were enrolled in both studies and 35 in US and 32 in Japan had adequate samples for PK evaluation. The PK parameters were calculated by non-compartment analysis method and were compared in the US and Japanese populations. The geometric mean ratios (90% confidence intervals) of area under the concentration-time curve, steady state concentration and amount excreted into urine between Japanese and US populations were 1.068 (0.932-1.224), 1.141 (0.996-1.307) and 0.981 (0.855-1.125), respectively. There appear to be no PK differences between the US and Japanese patients with solid tumors or NHL. PMID:23138529

    Malignant pleural mesothelioma (MPM) is an aggressive disease that is resistant to conventional therapies. Cell lines are useful models for studying the biological characteristics of tumors; therefore, the establishment of MPM cell lines is valuable for exploring novel therapeutic strategies for MPM. In the present study, 4 MPM cell lines (YUMC8, YUMC44, YUMC63, and YUMC64) were established, which consisted of 2 epithelioid and 2 sarcomatoid mesothelioma histological subtypes, from Japanese patients with MPM. The DNA methylation status, mutations, copy number gains, protein expression of representative genes, and the sensitivity to several drugs were examined in these 4 cell lines. Methylation of P16 was demonstrated in 3/4 cell lines, in which the protein expression of p16 was lost. Methylation of RASSF1A was observed in 3/4 cell lines. Copy number gains of EGFR, HER2 or MET were not detected in the 4 cell lines. Mutations in various genes, including EGFR, KRAS, HER2, BRAF, and PIK3CA, which are frequently detected in non-small cell lung cancer, were not detected in the 4 cell lines. microRNA-34b/c is a direct transcriptional target of p53 and is often silenced in MPM by promoter methylation. In the present study, miR-34b/c was heavily methylated in 2/4 established MPM cell lines. For cell adhesion molecules, E-cadherin expression was detected in the 2 epithelioid MPM cell lines, whereas N-cadherin expression was detected in all 4 established cell lines by western blotting. Vimentin was strongly expressed in the 2 sarcomatoid MPM cell lines. None of the established MPM cell lines demonstrated significant responses to the drugs tested, including NVP-AUY922, 17-DMAG, Trichostatin A, and Vorinostat. Although novel molecular findings were not observed in the current characterization of these MPM cell lines, these lines will be useful for future extensive analyses of the biological behavior of MPM and the development of novel therapeutic strategies.

    This paper discusses the way informed psychiatrists are expected to handle dissociative patients in clinical situations, with a specific focus on dissociative identity disorders and dissociative fugue. On the initial interview with dissociative patients, information on their history of trauma and any nascent dissociative symptoms in their childhood should be carefully obtained. Their level of stress in their current life should also be assessed in order to understand their symptomatology, as well as to predict their future clinical course. A psychoeducational approach is crucial; it might be helpful to give information on dissociative disorder to these patients as well as their family members in order to promote their adherence to treatment. Regarding the symptomatology of dissociative disorders, detailed symptoms and the general clinical course are presented. It was stressed that dissociative identity disorder and dissociative fugue, the most high-profile dissociative disorders, are essentially different in their etiology and clinical presentation. Dissociative disorders are often confused with and misdiagnosed as psychotic disorders, such as schizophrenia. Other conditions considered in terms of the differential diagnosis include borderline personality disorder as well as temporal lobe epilepsy. Lastly, the therapeutic approach to dissociative identity disorder is discussed. Each dissociative identity should be understood as potentially representing some traumatically stressful event in the past. The therapist should be careful not to excessively promote the creation or elaboration of any dissociative identities. Three stages are proposed in the individual psychotherapeutic process. In the initial stage, a secure environment and stabilization of symptoms should be sought. The second stage consists of aiding the "host" personality to make use of other more adaptive coping skills in their life. The third stage involves coaching as well as continuous awareness of

    Guidelines have recommended single pool Kt/V > 1.2 as the minimum dose for chronic hemodialysis (HD) patients on thrice weekly HD. The Dialysis Outcomes and Practice Patterns Study (DOPPS) has shown that "low Kt/V" (<1.2) is more prevalent in Japan than many other countries, though survival is longer in Japan. We examined trends in low Kt/V, dialysis practices associated with low Kt/V, and associations between Kt/V and mortality overall and by gender in Japanese dialysis patients. We analyzed 5784 HD patients from Japan DOPPS (1999-2011), restricted to patients dialyzing for >1 year and receiving thrice weekly dialysis. Logistic regression models estimated the relationships of patient characteristics with Kt/V. Logistic models also were used to estimate the proportion of low Kt/V cases attributable to various treatment practices. Multivariable Cox regression was used to estimate the associations of low Kt/V, blood flow rate (BFR), and treatment time (TT), with all-cause mortality. From 1999 to 2009, the prevalence of low Kt/V declined in men (37-27%) and women (15-10%). BFR <200 mL/min, TT <240 minutes, and dialyzate flow rate (DFR) < 500 mL/min were common (35, 13, and 19% of patients, respectively) and strongly associated with low Kt/V. Fifteen percent of low Kt/V cases were attributable to BFR <200 and 13% to TT <240, compared to only 3% for DFR <500. Lower Kt/V was associated with elevated mortality, more so among women (hazard ratio [HR] = 1.13 per 0.1 lower Kt/V, 95% CI: 1.07-1.20) than among men (HR = 1.06 per 0.1 lower Kt/V, 95% CI: 1.00-1.12). The relatively large proportion of low Kt/V cases in Japanese facilities may potentially be reduced 30% by increasing BFR to 200 mL/min and TT to 4 hours thrice weekly in HD patients. Associations of low Kt/V with elevated mortality suggest that modification of these practices may further improve survival for Japanese HD patients. PMID:24612374

    To evaluate the National Comprehensive Cancer Network (NCCN) International Prognostic Index (IPI), we analyzed 284 patients treated with the combination of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in our institution in Japan. Their 5-year overall survival (OS) by risk level was 80.7%, 74.8%, 55.4% and 67.5% (P=0.005); and their 5-year progression-free survival (PFS) was 76.8%, 78.6%, 63.7% and 58.3% (P=0.0722). The NCCN-IPI is a simple scale that uses conventional clinical factors, but did not reflect survival in our cohort. The NCCN-IPI may require further evaluation for different regions and ethnicities before adopting it for routine clinical use. PMID:27489766

    This 8-week, multi-center, open-label study assessed the safety and efficacy of LCZ696, a first-in-class angiotensin receptor neprilysin inhibitor, in Japanese patients with hypertension and renal dysfunction. Patients (n=32) with mean sitting systolic blood pressure (msSBP) ⩾140 mm Hg (after a 2-5-week washout of previous antihypertensive medications) and estimated glomerular filtration rate (eGFR) ⩾15 and <60 ml min(-1) 1.73 m(-2) received LCZ696 100 mg with an optional titration to 200 and 400 mg in a sequential manner starting from Week 2 in patients with inadequate BP control (msSBP ⩾130 mm Hg and mean sitting diastolic blood pressure (msDBP) ⩾80 mm Hg) and without safety concerns. Safety was assessed by monitoring and recording all adverse events (AEs) and change in potassium and creatinine. Efficacy was assessed as change from baseline in msSBP/msDBP. The mean baseline BP was 151.6/86.9 mm Hg, urinary albumin/creatinine ratio (UACR) geometric mean was 7.3 mg mmol(-1) and eGFR was ⩾30 and <60 in 25 (78.1%) patients and was ⩾15 and <30 in 7 (21.9%) patients. Fourteen (43.8%) patients reported at least one AE, which were mild in severity. No severe AEs or deaths were reported. There were no clinically meaningful changes in creatinine, potassium, blood urea nitrogen and eGFR. The geometric mean reduction in UACR was 15.1%, and the mean reduction in msSBP and msDBP was 20.5±11.3 and 8.3±6.3 mm Hg, respectively, from baseline to Week 8 end point. LCZ696 was generally safe and well tolerated and showed effective BP reduction in Japanese patients with hypertension and renal dysfunction without a decline in renal function. PMID:25693859

    2012-01-01

    Background Medical cannabis dispensaries following the social or hybrid model offer supplementary holistic services in addition to dispensing medical cannabis. Historically, alternative physical health services have been the norm for these dispensaries, including services such as yoga, acupuncture, or chiropractor visits. A clinical service dearth remains for medical cannabis patients seeking substance use, misuse, dependence, and mental health services. This study examined patient desires for various clinical services and level of willingness to participate in specific clinical services. Methods Anonymous survey data (N = 303) were collected at Harborside Health Center (HHC), a medical cannabis dispensary in Oakland, CA. The sample was 70% male, 48% Caucasian and 21% African American. The mean male age was 38 years old and female mean age was 30. Sixty two percent of the male participants and 44% of the female participants are single. Sixteen percent of the population reported having a domestic partner. Forty six percent of the participants are employed full time, 41% have completed at least some college, and 49% make less than $40,000 a year. Results A significant portion of the sample, 62%, indicated a desire to participate in free clinical services at HHC, 34% would like more information about substances and use, and 41% want to learn more about reducing harms from substance use. About one quarter of the participants marked "would" or "likely would" participate in individual services such as consultation. Approximately 20% indicated "would" or "likely would" participate in psycho-educational forums, harm reduction information sharing sessions, online support groups, and coping, life, and social skills group. There was little interest in traditional NA/AA 12-step groups or adapted 12-step groups. Conclusions Desired clinical services can be qualified as a combination of harm reduction, educational, skills-based, peer support and therapeutic individual and group

    Evolocumab (AMG 145), a fully human monoclonal antibody against PCSK9, significantly reduced low-density lipoprotein cholesterol (LDL-C) levels in phase 2 and 3 studies. This phase 3 study evaluated the efficacy and safety of evolocumab plus atorvastatin in Japanese patients with hyperlipidemia or mixed dyslipidemia and high cardiovascular risk. Patients were randomized to atorvastatin 5 or 20 mg/day for 4 weeks. Subsequently, patients underwent second randomization to evolocumab 140 mg biweekly (Q2W) or 420 mg monthly (QM) or placebo Q2W or QM. Coprimary end points were % change from baseline in LDL-C at week 12 and mean of weeks 10 and 12. Secondary end points included change and % change in other lipids and proportion of patients reaching LDL-C <70 mg/dl. Adverse events and laboratory values were recorded. Four hundred four patients were randomized to study drug. At baseline, the mean (SD) age was 61 (10) years (placebo) and 62 (11) years (evolocumab); 39% and 40% were women; 14% and 12% had cerebrovascular or peripheral arterial disease; and 51% and 47% had diabetes. At entry, mean (SD) calculated LDL-C was 128 (23) mg/dL; after stabilization on atorvastatin 5 and 20 mg/day, baseline LDL-C levels were 118 (35) and 94 (24) mg/dL, respectively. Mean LDL-C reductions at week 12 for evolocumab versus placebo ranged from 67% to 76%. No imbalances were observed in adverse events between treatment groups. Efficacy and safety for Q2W or QM evolocumab dosing were similar. In conclusion, in high-risk Japanese patients receiving stable statin therapy, evolocumab markedly reduced LDL-C and was well tolerated. PMID:26547291

    European studies have revealed that the ABCB11 c.1331T>C (V444A) polymorphism (rs2287622) C-allele frequency is higher among patients with drug-induced cholestasis. Given the low incidence of this disease, however, this association has not been sufficiently elucidated. We aimed to investigate the significance of this polymorphism in Japanese patients. We determined ABCB11 V444A polymorphism frequencies and HLA genotypes in two independent drug-induced cholestasis cohorts. Expression and taurocholate transport activity of proteins from 444A variants were analyzed using Madin-Darby canine kidney II cells. In cohort 1 (n = 40), the V444A polymorphism C-allele frequency (66%) was lower than that in controls (n = 190, 78%), but this difference was not significant (P = 0.09). In cohort 2 (n = 119), comprising patients with cholestatic (n = 19), hepatocellular (n = 74), and mixed (n = 26) liver injuries, the C-allele frequency was lower among patients with cholestatic liver injury (68%) than among those with hepatocellular (75%) or mixed liver injury (83%), although this difference was not significant. In cohort 1, HLA-A*0201 was observed more frequently in patients (22%) than in controls [11%; P = 0.003; odds ratio, 2.4 (95% confidence interval, 1.4-4.0)]. Taurocholate transport activity of 444A-encoded protein was significantly lower than that of 444V-encoded protein (81% of 444V, P < 0.05) because of the reduced protein stability. In conclusion, ABCB11 444A had slightly reduced transport activity, but it did not contribute to the occurrence of drug-induced cholestasis in Japanese patients. Therefore, genetic susceptibility to acquired cholestasis may differ considerably by ethnicity. PMID:25713208

    Japanese encephalitis (JE) is an inflammation of the central nervous system in humans and animals, specifically horses and cattle. The disease, which can sometimes be fatal, is caused by the flavivirus Japanese encephalitis virus (JEV), of which there are five genotypes (genotypes 1, 2, 3, 4 and 5). The transmission cycle of the virus involves pigs and wild birds as virus amplifiers and mosquitoes as vectors for transferring the virus between amplifying hosts and to dead- end hosts, i.e. humans, horses and cattle. In horses and cattle the disease is usually asymptomatic, but when clinical signs do occur they include fever, decreased appetite, frothing at the mouth, rigidity of the legs and recumbency, and neurological signs, such as convulsive fits, circling, marked depression and disordered consciousness. In pigs, it can cause abortion and stillbirths. At present, the virus is detected in a wide area covering eastern and southern Asia, Indonesia, northern Australia, Papua New Guinea and Pakistan. JEV RNA has also been detected in Italy, first in dead birds in 1997 and 2000 and then in mosquitoes in 2010. Genotype shift, i.e. a change of genotype from genotype 3 to genotype 1, has occurred in some countries, namely Japan, South Korea, Chinese Taipei and Vietnam. Laboratory methods are available for confirming the causative agent of the disease. There are control measures to prevent or minimise infection and, among them, vaccination is one of the most important and one which should be adopted in endemic and epidemic areas. PMID:26601447

    Japanese encephalitis (JE) is an infectious disease of the central nervous system caused by Japanese encephalitis virus (JEV), a zoonotic mosquito-borne flavivirus. JEV is prevalent in much of Asia and the Western Pacific, with over 4 billion people living at risk of infection. In the absence of antiviral intervention, vaccination is the only strategy to develop long-term sustainable protection against JEV infection. Over the past half-century, a mouse brain-derived inactivated vaccine has been used internationally for active immunization. To date, however, JEV is still a clinically important, emerging, and re-emerging human pathogen of global significance. In recent years, production of the mouse brain-derived vaccine has been discontinued, but 3 new cell culture-derived vaccines are available in various parts of the world. Here we review current aspects of JEV biology, summarize the 4 types of JEV vaccine, and discuss the potential of an infectious JEV cDNA technology for future vaccine development. PMID:24161909

    Genetic risk factors for ticlopidine-induced hepatotoxicity were determined in 22 Japanese patients with ticlopidine-induced hepatotoxicity and 85 Japanese patients who tolerated ticlopidine therapy without experiencing adverse reactions. There was a significant correlation between ticlopidine-induced hepatotoxicity and five human leukocyte antigen (HLA) alleles: HLA-A*3303, HLA-B*4403, HLA-Cw*1403, HLA-DRB1*1302 and HLA-DQB1*0604 (corrected probability (P)-value (Pc)<0.01). In particular HLA-A*3303 was present in 15 (68%) of the 22 patients with ticlopidine-induced hepatotoxicity and in 12 (14%) of the 85 ticlopidine-tolerant patients (odds ratio, 13.04; 95% confidence interval (CI), 4.40-38.59; the corrected P-value (Pc)=1.24 x 10(-5)). HLA-A*3303 was present in 12 (86%) of the 14 patients with ticlopidine-induced cholestatic hepatotoxicity (odds ratio, 36.50; 95% CI, 7.25-183.82, Pc=7.32 x 10(-7)). Ticlopidine-induced severe cholestatic hepatotoxicity occurred more frequently in subjects with HLA-A*3303 and its haplotype in Japanese patients. These findings may explain the high incidence of ticlopidine-induced hepatotoxicity in Japanese patients mediated via an immune-mediated mechanism. PMID:17339877

    Background In Japan, the legislation directing treatment of offenders with psychiatric disorders was enacted in 2005. Neuropsychological impairment is highly related to functional outcomes in patients with psychiatric disorders, and several studies have suggested an association between neuropsychological impairment and violent behaviors. However, there have been no studies of neuropsychological impairment in forensic patients covered by the Japanese legislation. This study is designed to examine the neuropsychological characteristics of forensic patients in comparison to healthy controls and to assess the relationship between neuropsychological impairment and violence risk. Methods Seventy-one forensic patients with psychiatric disorders and 54 healthy controls (matched by age, gender, and education) were enrolled. The CogState Battery (CSB) consisting of eight cognitive domains, the Iowa Gambling Task (IGT) to test emotion-based decision making, and psychological measures of violence risk including psychopathy were used. Results Forensic patients exhibited poorer performances on all CSB subtests and the IGT than controls. For each group, partial correlational analyses indicated that poor IGT performance was related to psychopathy, especially antisocial behavior. In forensic patients, the CSB composite score was associated with risk factors for future violent behavior, including stress and noncompliance with remediation attempts. Conclusion Forensic patients with psychiatric disorders exhibit a wide range of neuropsychological impairments, and these findings suggest that neuropsychological impairment may increase the risk of violent behavior. Therefore, the treatment of neuropsychological impairment in forensic patients with psychiatric disorders is necessary to improve functional outcomes as well as to prevent violence. PMID:26824701

    Target exon resequencing using Massively Parallel DNA Sequencing (MPS) is a new powerful strategy to discover causative genes in rare Mendelian disorders such as deafness. We attempted to identify genomic variations responsible for deafness by massive sequencing of the exons of 112 target candidate genes. By the analysis of 216randomly selected Japanese deafness patients (120 early-onset and 96 late-detected), who had already been evaluated for common genes/mutations by Invader assay and of which 48 had already been diagnosed, we efficiently identified causative mutations and/or mutation candidates in 57 genes. Approximately 86.6% (187/216) of the patients had at least one mutation. Of the 187 patients, in 69 the etiology of the hearing loss was completely explained. To determine which genes have the greatest impact on deafness etiology, the number of mutations was counted, showing that those in GJB2 were exceptionally higher, followed by mutations in SLC26A4, USH2A, GPR98, MYO15A, COL4A5 and CDH23. The present data suggested that targeted exon sequencing of selected genes using the MPS technology followed by the appropriate filtering algorithm will be able to identify rare responsible genes including new candidate genes for individual patients with deafness, and improve molecular diagnosis. In addition, using a large number of patients, the present study clarified the molecular epidemiology of deafness in Japanese. GJB2 is the most prevalent causative gene, and the major (commonly found) gene mutations cause 30–40% of deafness while the remainder of hearing loss is the result of various rare genes/mutations that have been difficult to diagnose by the conventional one-by-one approach. In conclusion, target exon resequencing using MPS technology is a suitable method to discover common and rare causative genes for a highly heterogeneous monogenic disease like hearing loss.

    Abstract Objectives. To evaluate the long-term efficacy and safety of certolizumab pegol (CZP) plus methotrexate treatment and to assess the efficacy of two CZP maintenance dosing schedules in Japanese rheumatoid arthritis (RA) patients with an inadequate response to methotrexate. Methods. J-RAPID double-blind patients were entered into an open-label extension (OLE) study. Patients withdrawn due to lack of efficacy at 16 weeks and double-blind completers without a week-24 American College of Rheumatology (ACR) 20 response received CZP 200 mg every other week (Q2W) plus methotrexate. Double-blind completers with week-24 ACR20 responses were randomized to CZP 200 mg Q2W plus methotrexate or CZP 400 mg every 4 weeks plus methotrexate. Results. The ACR20/ACR50/ACR70 response rates of double-blind completers (n = 204) were 89.7%/67.2%/36.3% at OLE entry and 95.6%/84.8%/58.3% at 52 weeks, respectively. Other clinical, functional and radiographic outcomes were sustained with long-term CZP plus methotrexate. Long-term treatment with CZP was well-tolerated with no new unexpected adverse events observed. The efficacy and safety of CZP treatment were similar between the two dosing schedules. Conclusions. Continued CZP administration with methotrexate maintained efficacy over 52 weeks and was well-tolerated for Japanese RA patients. No obvious differences in clinical efficacy and safety were observed between the two dosing schedules, giving flexibility in maintenance administration schedules. PMID:24593170

    [Purpose] This study aimed to elucidate characteristics of postoperative physical functional recovery in octogenarians undergoing coronary artery bypass graft surgery. [Subjects and Methods] This was a multi-center, retrospective study. Nine hundred and twenty-seven elective isolated coronary artery bypass graft surgeries were evaluated (746 males and 181 females, mean age: 68.6 years, range: 31–86 years). Participants were stratified according to age < 80 years (n = 840; mean age, 67.1; range, 31–79) or > 80 years (n = 87; mean age, 82.2; range, 80–86). Patient characteristics and postoperative physical functional recovery outcomes were compared between groups. [Results] There was no significant difference between groups when considering the postoperative day at which patients could sit on the edge of the bed, stand at bedside, or walk around the bed. The postoperative day at which patients could walk 100 m independently was later in octogenarians, when compared with non-octogenarians (6.1 ± 3.2 days vs. 4.9 ± 3.9 days). In octogenarians, the percentage of patients who could walk 100 m independently within 8 days after surgery was 79.5%. [Conclusion] A postoperative target time in octogenarians for independent walking, following coronary artery bypass grafting, can be set at approximately 6 days. PMID:27065553

    The long-term antihypertensive efficacy and safety of losartan/hydrochlorothiazide (HCTZ) combinations have not been appropriately evaluated in Japan. In this study, treated hypertensive patients taking angiotensin-receptor blocker (ARB) or angiotensin-converting enzyme inhibitor (ACEI) regimens not at blood pressure (BP) goals proposed by the Japanese Society of Hypertension (JSH) were switched to losartan/HCTZ combinations and followed for 1 year. Data analysis included 244 patients aged 64.5+/-10.7 years, 56% male, 27% with diabetes mellitus and 36% with dyslipidemia. Pre-switching BP 157+/-16/88+/-10 mm Hg promptly decreased and maintained a steady state, reaching 132+/-15/77+/-9 mm Hg (P<0.001) 1 year later. After 1 year of treatment, 50% of patients cleared the goals of the JSH guideline for systolic BP and 79% for diastolic BP. Patients with maximal doses of ARBs tended to show larger decreases in BP (159+/-11/90+/-10 to 128+/-10/75+/-8 mm Hg, P<0.001, n=32). Clinical and laboratory adverse events were reported for 29 patients (11%), but serious abnormalities were not observed. In particular, plasma levels of uric acid (UA) were well-maintained for 1 year, and significant decreases in UA were observed in patients with higher levels of UA (>/=7.0 mg dl(-1)). Losartan/HCTZ combinations showed strong and steady hypotensive abilities and acceptable safety and tolerability in patients currently not at BP goals with regimens including ARBs or ACEIs in Japan.

    Japanese mathematical scientists including astronomers, physicists, and mathematicians obtain ideas in Japanese, discuss their problems in Japanese, and arrive at conclusions in Japanese, and yet they write their results in foreign languages such as English. This uncomfortable situation has continued for nearly one hundred years and has had serious effects on Japanese science. In this short report, the author discusses and analyses these effects. In order to put Japanese science on a sound basis, the author proposes to increase the number of articles, reviews and textbooks in Japanese, first by translation and second by the voluntary efforts of scientists themselves. As centers devoted to this activity, the author proposes to construct "Airborne Libraries" which are maintained and accumulate in an electronic form the scientific documents written in Japanese.

    X-linked hypophosphatemic rickets (XLH) is a dominant inherited disorder characterized by renal phosphate wasting, aberrant vitamin D metabolism, and abnormal bone mineralization. Inactivating mutations in the gene encoding phosphate-regulating gene with homologies to endopeptidases on the X chromosome (PHEX) have been found to be associated with XLH. Here, we report a 16-year-old female patient affected by hypophosphatemic rickets. We evaluated her serum fibroblast growth factor 23 (FGF23) levels and conducted sequence analysis of the disease-associated genes of FGF23-related hypophosphatemic rickets: PHEX, FGF23, dentin matrix protein 1, and ectonucleotide pyrophosphatase/phosphodiesterase 1. She was diagnosed with XLH based on her clinical features and family history. Additionally, we observed elevated FGF23 levels and a novel PHEX exon 9 mutation (c.947G>T; p.Gly316Val) inherited from her father. Although bioinformatics showed that the mutation was neutral, Gly316 is perfectly conserved among humans, mice, and rats, and there were no mutations in other FGF23-related rickets genes, suggesting that in silico analysis is limited in determining mutation pathogenicity. In summary, we present a female patient and her father with XLH harboring a novel PHEX mutation that appears to be causative of disease. Measurement of FGF23 for hypophosphatemic patients is therefore useful for the diagnosis of FGF23-dependent hypophosphatemia. PMID:25861491

    Routine monitoring of clinicopathologic data is a critical component in the management of older patients because blood and urine testing allows the veterinarian to monitor trends in laboratory parameters, which may be the early indicators of disease. Laboratory profiling often provides an objective and sensitive indicator of developing disease before obvious clinical signs or physical examination abnormalities are observed. The primary key to the power of this evaluation is that the data are collected year after year during wellness checks and are examined serially. Chronic renal failure, chronic active hepatitis, canine hyperadrenocorticism, diabetes mellitus, and feline hyperthyroidism were reviewed and expected laboratory findings are summarized.

    We herein report the case of a 66-year-old Japanese man with acute-onset type 1 diabetes mellitus (T1D) accompanied by pernicious anemia. After 2 weeks of polyuria, the patient developed insulin-deficient hyperglycemia with diabetic ketoacidosis in the absence of verifiable islet-related autoantibodies and began insulin therapy in 2001. Eight years later, he developed gastric autoantibody-positive pernicious anemia and began methylcobalamin treatment. Previous studies have reported cases of slowly progressive autoimmune T1D concomitant with pernicious anemia. The present case suggests that potential associations with organ-specific autoimmune disorders should be considered during the long-term follow-up of T1D patients, even though verifiable islet-related autoantibodies are undetectable.

    Objective Our objective is to determine appropriate specifications for smaller tongue blade for Japanese pediatric patients with cleft palate (CP) and mandibular micrognathia. Patients We investigated 59 patients who underwent palatoplasty. Patients were divided into two groups: the micrognathia (MG) group consisted of 11 patients and the normognathia (NG) group consisted of 48 patients. Interventions The following five items were investigated retrospectively: (1) gender, (2) cleft type, (3) age at the time of surgery, (4) weight at the time of surgery, and (5) distance from the tongue blade base to the posterior pharyngeal wall (Dis). Results There was a significant difference (P < .01) in age at the time of surgery and in Dis between groups, but not in weight. The minimum values were 55 mm for the MG group. As for correlations between age and weight at the time of surgery, the P values for the MG and NG groups were .993 and .052, respectively. As for correlations between weight at the time of surgery and Dis, the P values for the MG and NG groups were .987 and .099, respectively. Conclusions It was difficult to predict Dis on the basis of the patient's age and weight measured preoperatively. The minimum Dis was 55 mm, equal to the length from the base to the tip of the Dingman Mouth Gag tongue blade currently in use, suggesting that a tongue blade of approximately 50 mm in length, shorter than the current minimum specifications, may be appropriate.

    This phase I open-label study evaluated the tolerability of pegylated liposomal doxorubicin (PLD) and bortezomib combination in Japanese patients with relapsed or refractory multiple myeloma. Eligible patients (≥20 years) who had ≥1 line of prior chemotherapy received bortezomib 1.3 mg/m(2) rapid intravenous infusion on days 1, 4, 8 and 11 (each 21-day cycle), followed by PLD 30 mg/m(2) intravenous infusion on day 4 (each cycle), up to 6 cycles. Dose-limiting toxicity (DLT), defined as Grade 4 hematologic or Grade ≥3 non-hematologic, was evaluated through end of day 21. All three patients enrolled in the study developed DLTs [Grade 4 thrombocytopenia (n = 2) and Grade 3 ileus (n = 1)]. The study was, therefore, terminated without adding new patients, as per protocol-specified criteria. The most common Grade 3-4 adverse events (AEs) were hematologic, including thrombocytopenia, leucopenia, and neutropenia. The treatment was prematurely discontinued in all three patients due to AEs: Grade 3 bronchiolitis (serious AE), Grade 3 peripheral sensory neuropathy, and Grade 2 stomatitis. All patients achieved partial response (efficacy, secondary endpoint). In conclusion, the tolerability of PLD and bortezomib combination at dose levels approved in various countries was not confirmed in relapsed or refractory multiple myeloma patients from Japan.

    Larva migrans syndrome (LMS) caused by Toxocara and Ascaris roundworms is generally believed to be more common in children, while a report from Japan suggests that it is more common in adults. We conducted a large-scale retrospective study to confirm these findings and to clarify what caused the difference between Japan and other countries, to reveal overlooked aspects of this disease. The clinical information of 911 cases which we diagnosed as Toxocara or Ascaris LMS during 2001 and 2015 was analysed. Information used included age, sex, address (city or county), chief complaint, present history, dietary history, overseas travelling history, medical imaging findings and laboratory data (white blood cell count, peripheral blood eosinophil number and total IgE). The sex ratio of the disease was 2.37 (male/female = 641/270). The number of patients not younger than 20 years old were 97.8 and 95.1 % among males and females, respectively. Major disease types were visceral, ocular, neural and asymptomatic. The visceral type was more prevalent in older patients, while younger patients were more vulnerable to ocular symptoms. More than two-thirds of the patients whose dietary habits were recorded had a history of ingesting raw or undercooked animal meat. LMS caused by Toxocara or Ascaris is primarily a disease of adult males in Japan, who probably acquired infections by eating raw or undercooked animal meat/liver. Healthcare specialists should draw public attention to the risk of raw or undercooked animal meat in Europe as well. PMID:27272122

    Purpose: To reveal a predictive factor for biochemical recurrence (BCR) after permanent prostate brachytherapy (PPB) using iodine-125 seed implantation in patients with localized prostate cancer classified as low or intermediate risk based on National Comprehensive Cancer Network (NCCN) guidelines. Methods and Materials: From January 2004 to December 2009, 414 consecutive Japanese patients with clinically localized prostate cancer classified as low or intermediate risk based on the NCCN guidelines were treated with PPB. The clinical factors including pathological data reviewed by a central pathologist and follow-up data were prospectively collected. Kaplan-Meier and Cox regression analyses were used to assess the factors associated with BCR. Results: Median follow-up was 36.5 months. The 2-, 3-, 4-, and 5-year BCR-free rates using the Phoenix definition were 98.3%, 96.0%, 91.6%, and 87.0%, respectively. On univariate analysis, the Gleason score, especially primary Gleason grade 4 in biopsy specimens, was a strong predicting factor (p < 0.0001), while age, initial prostate-specific antigen (PSA) level, T stage, and minimal dose delivered to 90% of the prostate volume (D90) were insignificant. Multivariate analysis indicated that a primary Gleason grade 4 was the most powerful prognostic factor associated with BCR (hazard ratio = 6.576, 95% confidence interval, 2.597-16.468, p < 0.0001). Conclusions: A primary Gleason grade 4 carried a worse BCR prognosis than the primary grade 3 in patients treated with PPB. Therefore, the indication for PPB in patients with a Gleason sum of 4 + 3 deserves careful and thoughtful consideration.

    Objective This study compared the efficacy and safety of azelnidipine with that of trichlormethiazide in Japanese type 2 diabetic patients with hypertension. Methods In a multicenter, open-label trial, 240 patients with adequately controlled diabetes (HbA1c ≤ 7.0%) under lifestyle modification and/or administration of hypoglycemic agents and inadequately controlled hypertension (systolic blood pressure [sBP] ≥ 130 mmHg or diastolic blood pressure [dBP] ≥ 80 mmHg) who were being treated with olmesartan were enrolled. Participants were randomly assigned to an azelnidipine group or a trichlormethiazide group and were followed up for 48 weeks. Main outcome measure was the difference in the change in HbA1c levels from the baseline values at 48 weeks between these two groups. Results Of the 240 subjects that were enrolled, 209 subjects (azelnidipine group: 103 patients, trichlormethiazide group: 106 patients) completed this trial. At 48 weeks, the following changes were observed in the azelnidipine and trichlormethiazide groups, respectively: HbA1c levels, 0.19 ± 0.52% and 0.19 ± 0.54%; sBP/dBP, -10.7 ± 9.6/-6.6 ± 6.6 mmHg and -7.1 ± 7.7/-3.3 ± 6.1 mmHg (P < 0.001 for both sBP and dBP). In both groups, dizziness (12 patients [11.7%] and 16 patients [15.1%]) and edema (16 patients [15.5%] and 7 patients [6.6%], P = 0.047) were observed during the 48-week follow-up period. Conclusions Azelnidipine was more effective for controlling blood pressure than trichlormethiazide in Japanese type 2 diabetes patients, whereas trichlormethiazide was more effective for reducing albuminuria than azelnidipine. Both of these agents, however, similarly exacerbated glycemic control in type 2 diabetic patients with hypertension. Trial Registration UMIN 000006081. PMID:25938807

    To assess the contribution to mutagenesis by human DNA repair defects, a UV-treated shuttle vector plasmid, pZ189, was passed through fibroblasts derived from Japanese xeroderma pigmentosum (XP) patients in two different DNA repair complementation groups (A and F). Patients with XP have clinical and cellular UV hypersensitivity, increased frequency of skin cancer, and defects in DNA repair. The XP DNA repair defects represented by complementation groups A (XP-A) and F (XP-F) are more common in Japan than in Europe or the United States. In comparison to results with DNA repair-proficient human cells (W138-VA13), UV-treated pZ189 passed through the XP-A (XP2OS(SV)) or XP-F (XP2YO(SV)) cells showed fewer surviving plasmids (XP-A less than XP-F) and a higher frequency of mutated plasmids (XP-A greater than XP-F). Base sequence analysis of more than 200 mutated plasmids showed the major type of base substitution mutation to be the G:C----A:T transition with all three cell lines. The XP-A and XP-F cells revealed a higher frequency of G:C----A:T transitions and a lower frequency of transversions among plasmids with single or tandem mutations and a lower frequency of plasmids with multiple point mutations compared to the normal line. The spectrum of mutations in pZ189 with the XP-A cells was similar to that with the XP-F cells. Seventy-six to 91% of the single base substitution mutations occurred at G:C base pairs in which the 5{prime}-neighboring base of the cytosine was thymine or cytosine. These studies indicate that the DNA repair defects in Japanese XP patients in complementation groups A and F result in different frequencies of plasmid survival and mutagenesis but in similar types of mutagenic abnormalities despite marked differences in clinical features.

    Objectives This is the first clinical trial of this type in Japan, designed to analyze two important aspects of Alzheimer’s disease (AD) management using medium-chain triglycerides. Axona was administered for 3 months (40 g of powder containing 20 g of caprylic triglycerides). We used an indurating, four-step dose-titration method (from 10 to 40 g per day) for 7 days before the trial, and examined the tolerance and adverse effects of this intervention. We also investigated its effect on cognitive function in mild-to-moderate AD patients. Patients and methods This was a clinical intervention in 22 Japanese patients with sporadic AD at a mild-to-moderate stage (ten females, 12 males), mean age (± standard deviation) 63.9 (±8.5) years, Mini-Mental State Examination (MMSE) score, 10–25, seven patients were ApoE4-positive. During Axona administration, we examined changes in cognitive function by obtaining MMSE and AD assessment-scale scores. Intolerance and serum ketone concentrations were also examined. Results The tolerance of Axona was good, without severe gastrointestinal adverse effects. Axona did not improve cognitive function in our sample of AD patients, even in those patients without the ApoE4 allele. However, some ApoE4-negative patients with baseline MMSE score ≥14 showed improvement in their cognitive functions. Conclusion The modified dose-titration method, starting with a low dose of Axona, decreased gastrointestinal adverse effects in Japanese patients. Axona might be effective for some relatively mildly affected patients with AD (with cognitive function MMSE score of ≥14 and lacking the ApoE4 allele). PMID:26811674

    Background and Aims: Data from an all-cases post-marketing study were used to evaluate the safety and effectiveness of adalimumab in Japanese patients with Crohn’s disease [CD]. Methods: Patients received adalimumab for 24 weeks. Data from all patients [n = 1693] were used for the safety assessment. Data from patients with CD activity index [CDAI] ≥ 150 at baseline were used for the effectiveness assessment. Results: The most frequent serious adverse drug reaction [ADR] was infection and infestations [6.6 events/100 patient-years]. The risk of serious infections increased in patients who had a history of malignancy and those with concomitant corticosteroid use. Of 415 patients who had switched from another anti-tumour necrosis factor alpha [TNFα] agent to adalimumab due to ADRs, 7.2% discontinued due to ADRs to adalimumab. Ten of 13 patients with a history of tuberculosis [TB] received prophylactic medication, and none developed TB. TB developed in one patient with no history of TB or anti-TB prophylaxis. Remission rates were 41.3% and 32.4% at 4 and 24 weeks, respectively. Remission rates did not differ between patients with and without concomitant use of immunomodulators. Predictive variables for increased effectiveness were CDAI ≤ 220 and disease duration of ≤ 2 years. Perianal lesions and loss of response to previous anti-TNFα agents affected effectiveness. Conclusions: The most frequent serious ADR was infection. Adalimumab significantly reduced disease activity, without any unexpected ADRs. Development of active TB during adalimumab therapy can be prevented through TB screening and prophylaxis. In patients who switched from another anti-TNFα agent to adalimumab due to ADRs, adalimumab was well tolerated. PMID:26961546

    Rett syndrome (RTT) is a severe X-linked dominant inheritance disorder with a wide spectrum of clinical manifestations. Mutations in Methyl CpG binding protein 2 (MECP2), Cyclin dependent kinase-like 5 (CDKL5) and Forkhead box G1 (FOXG1) have been associated with classic and/or variant RTT. This study was conducted to identify the responsible gene(s) in atypical RTT patient, and to examine the effect of the mutation on protein function. DNA sequence analysis showed a novel heterozygous mutation in CDKL5 identified as c.530A>G which resulted in an amino acid substitution at position 177, from tyrosine to cysteine. Genotyping analysis indicated that the mutation was not merely a single nucleotide polymorphism (SNP). We also revealed that patient's blood lymphocytes had random X-chromosome inactivation (XCI) pattern. Further examination by bioinformatics analysis demonstrated the mutation caused damage or deleterious in its protein. In addition, we demonstrated in vitro kinase assay of mutant protein showed impairment of its activity. Taken together, the results suggested the mutant CDKL5 was responsible for the disease.

    The Valsartan Amlodipine Randomized Trial, a multicenter, prospective, randomized, open-labeled, blinded-end point trial, was designed to compare the beneficial effects of the angiotensin II receptor blocker valsartan and the calcium channel blocker amlodipine on cardiovascular events in Japanese essential hypertensive patients. The primary end point was a composite of all-cause death, sudden death, cerebrovascular death, cardiac events, vascular events and renal events. The secondary endpoints were effects on left ventricular hypertrophy, cardiac sympathetic nerve activity and renal function. A total of 1021 patients were enrolled in the present trial. The mean follow-up period was 3.4 years. There were no significant differences in blood pressure (BP) levels between the valsartan group and the amlodipine group throughout the trial. There was no significant difference in the primary endpoint between the two groups (hazard ratio: 1.0, P = 0.843). No difference in any event category of the primary endpoint was noted for either group. However, we observed a significant reduction of left ventricular mass index, as determined by echocardiography, in the valsartan group compared with the amlodipine group. We also observed a significant decrease in cardiac sympathetic nerve activity in the valsartan group but not in the amlodipine group. Moreover, there was a significant reduction in the urinary albumin to creatinine ratio in the valsartan group but not in the amlodipine group. Therefore, although BP levels were well controlled and remained equal in the two groups, valsartan had more protective effects on the heart and kidney than amlodipine in Japanese hypertensive patients.

    Chromosome 22q11.2 deletion syndrome and genetic variations including single-nucleotide polymorphism (SNP) and copy number variation (CNV) in catechol-O-methyltransferase (COMT) situated at 22q11.2 remains controversial. Here, the genetic relationship between COMT and Japanese patients with schizophrenia was investigated by examining whether the SNPs correlated with schizophrenia based on a common disease-common variant hypothesis. Additionally, 22q11.2DS were screened based on a common disease-rare variant hypothesis; low-frequency CNVs situated at two COMT promoters and exons were investigated based on the low-frequency variants with an intermediate effect; and positive findings from the first stage were reconfirmed using a second-stage replication study including a larger sample size. Eight SNPs and 10 CNVs were investigated using Taqman SNP and CNV quantitative real-time polymerase chain reaction method. For the first-stage analysis, 513 unrelated Japanese patients with schizophrenia and 705 healthy controls were examined. For the second-stage replication study, positive findings from the first stage were further investigated using a larger sample size, namely 1,854 patients with schizophrenia and 2,137 controls. The first-stage analysis showed significant associations among schizophrenia, intronic SNP rs165774, CNV6 situated at promoter 1, CNV8 at exon 6, and CNV9 at exon 7. The second-stage study showed that intronic SNP rs165774 (χ(2)  = 8.327, P = 0.0039), CNV6 (χ(2)  = 19.66, P = 0.00005), and CNV8 (χ(2)  = 16.57, P = 0.00025) were significantly associated with schizophrenia. Large and rare CNVs as well as low-frequency CNVs and relatively small CNVs, namely <30 kb in COMT, may be genetic risk factors for schizophrenia. © 2016 Wiley Periodicals, Inc. PMID:26852906

    With the approval of pegfilgrastim, the use of dose-dense epirubicin and cyclophosphamide (EC) for breast cancer has become acceptable in Japan. Thus, we aimed to evaluate its safety and tolerability in Japanese patients. Nine breast cancer patients with a high risk of preoperative or postoperative recurrence received EC therapy(epirubicin 90 mg/m(2) and cyclo- phosphamide 600 mg/m(2))for 4 cycles every 2 weeks in combination with a subcutaneous injection of pegfilgrastim (3.6 mg) on day 2 of each cycle. Treatment was discontinued in 1 and extended in 1 of the 9 patients, and the mean relative dose intensity(RDI)was good at 0.93. No serious adverse events were observed, indicating good tolerability. The regimen has potential for use in cases in which the treatment dose needs to be increased. grade 4 neutropenia was observed in all the 9 patients on day 8, with 6 patients developing febrile neutropenia. In Japan, data on changes in neutrophil count associated with pegfilgrastim administration under anthracycline-based chemotherapy are currently insufficient, and further study is required.

    Obesity is a risk factor for atrial fibrillation (AF); however, obesity is associated with lower mortality in patients with established AF, a phenomenon known as the obesity paradox. Previous studies reported inconsistent results regarding effects of body weight on risk of cardiogenic embolism in patients with AF. To determine relation between body mass index (BMI) and prognosis among Japanese patients with nonvalvular AF (NVAF), a post hoc analysis was conducted using observational data in the J-RHYTHM Registry. Subjects were categorized as underweight (BMI <18.5), normal (18.5 to 24.9), overweight (25.0 to 29.9), or obese (≥30 kg/m(2)). End points included thromboembolism, major hemorrhaging, all-cause mortality, and cardiovascular mortality. Of the 7,406 patients with NVAF, 6,379 patients (70 ± 10 years old; BMI, 23.6 ± 3.9 kg/m(2)) having baseline BMI data constituted the study group. During the 2-year follow-up period, 111 patients had thromboembolism, 124 experienced major hemorrhage, and 159 died. Multivariate analysis with the Cox proportional hazards model showed that none of the BMI categories were independent predictors of thromboembolism. However, being underweight was an independent predictor of all-cause mortality (hazard ratio [HR] 2.45; 95% confidence interval [CI] 1.62 to 3.69; p <0.001) and cardiovascular mortality (HR 3.00, 95% CI 1.52 to 5.91, p = 0.001) when normal weight was used as the reference. Additionally, being overweight was a predictor of lower all-cause mortality (HR 0.60, 95% CI 0.37 to 0.95, p = 0.029). In conclusion, being underweight is associated with higher risks of all-cause and cardiovascular mortality compared with having a normal weight. Being overweight or obese is not associated with increased mortality among Japanese patients with NVAF. PMID:27255662

    Background/Aims Monitoring of serum ferritin levels is widely recommended in the management of anemia among patients on dialysis. However, associations between serum ferritin and mortality are unclear and there have been no investigations among patients undergoing peritoneal dialysis (PD). Methods Baseline data of 191,902 patients on dialysis (age, 65 ± 13 years; male, 61.1%; median dialysis duration, 62 months) were extracted from a nationwide dialysis registry in Japan at the end of 2007. Outcomes, such as one-year mortality, were then evaluated using the registry at the end of 2008. Results Within one year, a total of 15,284 (8.0%) patients had died, including 6,210 (3.2%) cardiovascular and 2,707 (1.4%) infection-related causes. Higher baseline serum ferritin levels were associated with higher mortality rates among patients undergoing hemodialysis (HD). In contrast, there were no clear associations between serum ferritin levels and mortality among PD patients. Multivariate Cox regression analysis of HD patients showed that those in the highest serum ferritin decile group had higher rates of all-cause and cardiovascular mortality than those in the lowest decile group (hazard ratio [HR], 1.54; 95% confidence interval [CI], 1.31–1.81 and HR, 1.44; 95% CI, 1.13–1.84, respectively), whereas associations with infection-related mortality became non-significant (HR, 1.14; 95% CI, 0.79–1.65). Conclusions Using Japanese nationwide dialysis registry, higher serum ferritin values were associated with mortality not in PD patients but in HD patients. PMID:26599216

    The author reports the findings from a qualitative study of diagnostic data obtained and interpreted by hospital nurses on the coping of adult patients and their families. Clinical data taken from taped interviews were transcribed and analyzed using grounded theory and analytic induction techniques. The data were then compared with diagnoses accepted for testing by NANDA. The phenomena described by the research did not match the NANDA constructs for individual and family coping problems. Nurses' assessments of coping response, however, fit within transactional theory. The use of the term "ineffective" to qualify coping was generally avoided. Ineffective coping, suggesting an outcome or product of coping, was not often considered applicable to the coping responses nurses found appropriate at specific times in specific situations.

    Congenital adrenal hypoplasia, an X-linked disorder, is characterized by primary adrenal insufficiency and frequent association with hypogonadotropic hypogonadism. The X-chromosome gene DAX-1 has been most recently identified and shown to be responsible for this disorder. We analyzed the DAX-1 genes of two unrelated Japanese patients with congenital adrenal hypoplasia and hypogonadotropic hypogonadism by using PCR amplification of genomic DNA and its complete exonic sequencing. In a family containing several affected individuals, the proband male patient had a stop codon (TGA) in place of tryptophan (TGG) at amino acid position 171. As expected, his mother was a heterozygous carrier for the mutation, whereas his father and unaffected brother did not carry this mutation. In another male patient with noncontributory family history, sequencing revealed a 1-bp (T) deletion at amino acid position 280, leading to a frame shift and, subsequently a premature stop codon at amino acid position 371. The presence of this mutation in the patients` genome was further confirmed by digestion of genomic PCR product with MspI created by this mutation. Family studies using MspI digestion of genomic PCR products revealed that neither parent of this individual carried the mutation. These results clearly indicate that congenital adrenal hypoplasia and hypogonadotropic hypogonadism result from not only inherited but also de novo mutation in the DAX-1 gene. 31 refs., 4 figs., 2 tabs.

    This paper reports a descriptive study, based on nursing records, of nursing diagnoses documented three months after the implementation of the NANDA-I classification at the University of São Paulo's Hospital Universitário (HU-USP) and proposes outcomes and interventions for the 3 most frequent diagnoses. The convenience sample (34% of the month's admissions) consisted of 30 charts of patients admitted in the Medical Clinic in August of 2004 (60% female, average age 60.9 +/- 23.1 years, mean length of stay = 5.8 +/- 2.7 days). The diagnoses documented on the admission day were manually transcribed from the charts and analyzed according to their frequency. There were 144 diagnoses (31 categories), with an average of 4.8 +/- 4.0 diagnoses per patient (range = 1-10). The most frequent were: acute pain (66.7%), impaired tissue integrity (63.3%), ineffective airway clearance (43.3%), risk of impaired skin integrity (36.7%), and impaired skin integrity (33.3%). The proposed outcomes and interventions are presented. PMID:17977375

    OBJECTIVE Assessment of the efficacy and safety of TAK-875 (a novel GPR40 agonist) in Japanese patients with type 2 diabetes inadequately controlled by diet/exercise. RESEARCH DESIGN AND METHODS This was a phase II, multicenter, randomized, double-blind, parallel-group, placebo-controlled, 12-week dose-ranging evaluation of TAK-875 (6.25–200 mg once daily) with the primary end point of change in A1C at week 12. A nonblinded group received 1 mg glimepiride once daily as an active control. RESULTS A total of 396 patients were randomized to receive TAK-875 (n = 299), placebo (n = 48), or glimepiride (n = 49). The least square mean changes in A1C at week 12 from baseline were as follows: 0.09% in the placebo group; −0.54, −0.67, −0.88, −1.27, −1.29, and −1.40% in the 6.25-, 12.5-, 25-, 50-, 100-, and 200-mg TAK-875 groups, respectively; and −1.32% in the 1-mg glimepiride group. All TAK-875 groups had statistically significant reductions in A1C compared with placebo (P < 0.0001), and those receiving ≥50 mg TAK-875 achieved reductions in A1C equivalent to those with glimepiride. Results for other glycemic parameters, including improvements during a meal tolerance test, mirrored these positive findings with TAK-875. There were no significant differences in incidence of adverse events among the groups and no dose-dependent changes in tolerability. Hypoglycemic episodes were reported in 0.7% of patients in the TAK-875 groups and in 4.1% of the glimepiride group. CONCLUSIONS TAK-875 produced clinically and statistically significant improvements in glycemic control in patients with type 2 diabetes inadequately controlled by diet and exercise, and it was well tolerated with a lower propensity to cause hypoglycemia.

    This study was designed to confirm the appropriateness of the dose setting for a Japanese phase III study of rivaroxaban in patients with non-valvular atrial fibrillation (NVAF), which had been based on model simulation employing phase II study data. The previously developed mixed-effects pharmacokinetic/pharmacodynamic (PK-PD) model, which consisted of an oral one-compartment model parameterized in terms of clearance, volume and a first-order absorption rate, was rebuilt and optimized using the data for 597 subjects from the Japanese phase III study, J-ROCKET AF. A mixed-effects modeling technique in NONMEM was used to quantify both unexplained inter-individual variability and inter-occasion variability, which are random effect parameters. The final PK and PK-PD models were evaluated to identify influential covariates. The empirical Bayes estimates of AUC and C(max) from the final PK model were consistent with the simulated results from the Japanese phase II study. There was no clear relationship between individual estimated exposures and safety-related events, and the estimated exposure levels were consistent with the global phase III data. Therefore, it was concluded that the dose selected for the phase III study with Japanese NVAF patients by means of model simulation employing phase II study data had been appropriate from the PK-PD perspective.

    ABSTRACT The application of neoadjuvant androgen deprivation (NAD) in prostate cancer leads to a reduction in prostate volume, and the trends in volume reduction differ according to the treatment duration of NAD. A reduction in volume during external beam radiation therapy may lead to the exposure of normal tissues to an unexpected dose. In fact, prostate volume reductions have primarily been reported in European and American institutions. Although the prostate volume of Japanese patients is known to be small, the trends in prostate volume change during radiation therapy remain unclear. In the present study, we aimed to evaluate the changes in prostate volume of Japanese patients during intensity-modulated radiation therapy (IMRT) with NAD. Nineteen Japanese patients with prostate cancer underwent IMRT with NAD. Kilovoltage computed tomography (CT) images were obtained for treatment planning and verification of the treatment position for each treatment fraction. The patients were divided into 3 groups based on the duration of NAD, as follows: NAD < 3 months (short NAD: S-NAD), 3 months ≤ NAD < 6 months (middle NAD: M-NAD), and NAD ≥ 6 months (long NAD: L-NAD). The prostate volume reductions at the 36th treatment fraction, relative to the planning CT, were 7.8%, 2.0%, and 1.7% for the S-NAD, M-NAD, and L-NAD groups, respectively. Prostate volume shrunk greater in the S-NAD group than in the M-NAD and L-NAD groups; this finding was consistent with those of previous studies. The prostate volume changes in Japanese patients were smaller compared to those in European and American patients. PMID:27578915

    Objective The authors explored the feasibility and possible benefit of tablet-based educational materials for patients in clinic waiting areas. Methods We distributed eight tablets preloaded with diagnosis-relevant information in two clinic waiting areas. Patients were surveyed about satisfaction, usability, and effects on learning. Technical issues were resolved. Results Thirty-seven of forty patients completed the survey. On average, the patients were satisfied in all categories. Conclusions Placing tablet-based educational materials in clinic waiting areas is relatively easy to implement. Patients using tablets reported satisfaction across three domains: usability, education, and satisfaction. PMID:27076806

    Persistent Müllerian duct syndrome (PMDS) is an autosomal recessive disorder of sex development (DSD) characterized by the presence of Müllerian duct derivatives in 46, XY phenotypic males. To date, more than 50 different mutations of the anti-Müllerian hormone gene (AMH) have been reported. Here, we report two novel mutations of AMH in a Japanese patient with PMDS. A 1-year-old male presented with bilateral cryptorchidism and normal male external genitalia. A laparoscopic surgery revealed a uterus and fallopian tubes. Serum AMH was very low. The patient's elder brother was also diagnosed as having PMDS at another hospital. Genetic analysis of AMH showed two novel mutations of p.N486T and p.V527L. Given that these two amino acids are well conserved among different species of AMH, the substitution of two amino acids might affect the normal function of AMH. In conclusion, PMDS should be included in differential diagnoses of cryptorchidism. PMID:25026127

    Background The Brief Assessment of Cognition in Schizophrenia (BACS) is an evaluation of cognitive function that can be completed with more cases. However, there are few studies that compare which factor, disease or aging, is a better determinant of performance on the BACS. The present study aimed to investigate the influences of disease and aging on BACS performance in schizophrenic patients using subjects with a wide range of ages. Methods Schizophrenic patients (n = 165) and a comparison group (n = 171) were recruited as subjects. All participants completed the Japanese language version of the BACS (BACS-J), and the influences of disease and aging on performance in the BACS were examined with the use of multiple regression analysis. Results There was a significant influence of diagnosis and level of education on all six tasks of the BACS and the performance and composite scores. In addition, age was found to influence five tasks and the composite score, the duration of illness influenced four tasks and the composite score, and gender influenced one task and the composite score. Conclusion The present study suggests that performance on the BACS was impaired not only by disease but also by level of education and aging. PMID:23983469

    Background Obesity is associated with advanced cardiovascular disease. However, some studies have reported the “obesity paradox” after percutaneous coronary intervention (PCI). The relationship between body mass index (BMI) and clinical outcomes after PCI has not been thoroughly investigated, especially in Asian populations. Methods We studied 10,142 patients who underwent PCI at 15 Japanese hospitals participating in the JCD-KICS registry from September 2008 to April 2013. Patients were divided into four groups according to BMI: underweight, BMI <18.5 (n=462); normal, BMI ≥18.5 and <25.0 (n=5,945); overweight, BMI ≥25.0 and <30.0 (n=3,100); and obese, BMI ≥30.0 (n=635). Results Patients with a high BMI were significantly younger (p<0.001) and had a higher incidence of coronary risk factors such as hypertension (p<0.001), hyperlipidemia (p<0.001), diabetes mellitus (p<0.001), and current smoking (p<0.001), than those with a low BMI. Importantly, patients in the underweight group had the worst in-hospital outcomes, including overall complications (underweight, normal, overweight, and obese groups: 20.4%, 11.5%, 8.4%, and 10.2%, p<0.001), in-hospital mortality (5.8%, 2.1%, 1.2%, and 2.7%, p<0.001), cardiogenic shock (3.5%, 2.0%, 1.5%, and 1.6%, p=0.018), bleeding complications (10.0%, 4.5%, 2.6%, and 2.8%, p<0.001), and receiving blood transfusion (7.6%, 2.7%, 1.6%, and 1.7%, p<0.001). BMI was inversely associated with bleeding complications after adjustment by multivariate logistic regression analysis (odds ratio, 0.95; 95% confidence interval, 0.92–0.98; p=0.002). In subgroup multivariate analysis of patients without cardiogenic shock, BMI was inversely associated with overall complications (OR, 0.98; 95% CI, 0.95–0.99; p=0.033) and bleeding complications (OR, 0.95; 95% CI, 0.91–0.98; p=0.006). Furthermore, there was a trend that BMI was moderately associated with in-hospital mortality (OR, 0.94; 95% CI, 0.88–1.01; p=0.091). Conclusions Lean

    Pranlukast (PLK) is a cysteinyl leukotriene receptor 1 antagonist approved for the treatment of bronchial asthma and allergic rhinitis in Japan. We previously reported that PLK dry syrup (DS) improved the total nasal symptom score, as well as sneezing, nasal discharge, and nasal obstruction scores over placebo. We investigated the efficacy of PLK DS with a noninvasive method in 10- to 15-year-old children with Japanese cedar (JC) pollinosis challenged with pollen allergen using an artificial exposure chamber (OHIO Chamber). Levels of eosinophil cationic protein (ECP) in nasal secretions, nasal obstruction score, and the relationship with nasal obstruction scores were analyzed. The estimated difference of means in ECP levels (PLK DS--placebo) was -22.9 micrograms (95% CI, -45.2 to -0.5), suggesting PLK DS reduced ECP significantly when compared with placebo (p = 0.0454). The difference in the least square means for nasal obstruction between the PLK DS and placebo was -0.25 (95% CI, -0.36 to -0.14) with a value of p < 0.0001. In addition, a statistically significant, although weak, positive correlation between the nasal obstruction score and nasal ECP levels was observed with placebo treatment (correlation coefficient = 0.2394; p = 0.0428). Moreover, the inhibition rate of nasal ECP with PLK DS relative to placebo was statistically significant, although weak, positively correlated with the inhibition rate of nasal obstruction (correlation coefficient = 0.3373; p = 0.0219). PLK DS significantly decreases nasal ECP levels and nasal obstruction score compared with placebo in children with JC pollinosis challenged with pollen allergen. Suppression of mucosal eosinophilic inflammation is one of the pathways by which PLK DS improves pollinosis-induced nasal obstruction. PMID:23394502

    Cushing's syndrome (CS) is a clinical state caused by chronic excess of glucocorticoid, and results in hypertension, impaired glucose tolerance, and dyslipidemia. Recently, a mild state of pituitary CS without typical Cushingoid appearance (subclinical Cushing's disease; SCD) has been identified. However, the true prevalence of SCD and its effect on metabolic disorders remain obscure. The aim of this prospective study was to determine the prevalence of SCD according to the guideline proposed by the working group of the Japanese Ministry of Health, Welfare and Labor, and to assess the outcome of surgery on metabolic disorders. The prevalence of SCD was investigated in 105 consecutive patients diagnosed with pituitary adenomas by MRI. ACTH-dependent hypercortisolism was diagnosed based on the results of the 0.5 mg dexamethasone suppression test (serum cortisol >3.0 μg/dL) plus one positive finding of the following two tests: midnight serum cortisol level >5.0 μg/dL or ACTH increase >50% after 1-deamino-5-D-arginine vasopressin (DDAVP) challenge. The final diagnosis of SCD was established by positive staining for ACTH in surgically-excised pituitary adenoma. Three patients (4.8%) were diagnosed with SCD among 62 patients with pituitary adenoma. Transsphenoidal adenomectomy partially resulted in improvement of blood pressure and glucose metabolism in SCD patients. Our results emphasize the importance of SCD screening in patients with pituitary tumors, especially in those patients with metabolic disorders. PMID:26536898

    Objective Switching from sulfonylureas to repaglinide in patients with type 2 diabetes improves glycemic control; however, the optimal dosage has not been fully evaluated. We designed to show that repaglinide was equivalent to sulfonylurea in Japanese patients with type 2 diabetes. We herein evaluated whether we could switch from sulfonylureas to repaglinide twice or thrice daily in Japanese adult patients who had been treated with anti-diabetic drugs, including sulfonylureas, and whose conditions were moderately well-controlled. Methods A total of 78 patients taking less than half the Japanese maximum dose of sulfonylurea were randomized into three groups: 26 in group A (switching from sulfonylureas to taking 0.25 or 0.5 mg of repaglinide just before breakfast and dinner twice daily), 27 in group B (switching from sulfonylureas to taking 0.25 or 0.5 mg of repaglinide just before meals thrice daily), and 25 in group C (continuing to take sulfonylurea). Blood samples were collected at 0, 1, 2, 3, and 4 months following the initiation of the maintenance period. Results The HbA1c and glycoalbumin levels did not significantly differ among the three groups after 4 months of treatment. Conclusion With the assumption that 1 mg of glimepiride is equivalent to 1.25 mg of glibenclamide or 40 mg of gliclazide, the administration of repaglinide (0.44 mg/meal) twice and thrice daily is similar to the efficacy of sulfonylurea (glimepiride 1.63-1.98 mg/day) after four months of treatment in Japanese patients with moderately well-controlled type 2 diabetes (HbA1c, 7-7.5%).

    Context: Denosumab 60 mg sc injection every 6 months for 36 months was well tolerated and effective in reducing the incidence of vertebral, nonvertebral, and hip fracture in predominantly Caucasian postmenopausal women with osteoporosis. Objective: The objective of this phase 3 fracture study was to examine the antifracture efficacy and safety of denosumab 60 mg in Japanese women and men with osteoporosis compared with placebo. Design and Setting: A randomized, double-blind, placebo-controlled trial with an open-label active comparator as a referential arm was conducted. Patients: Subjects were 1262 Japanese patients with osteoporosis aged 50 years or older, who had one to four prevalent vertebral fractures. Intervention: Subjects were randomly assigned to receive denosumab 60 mg sc every 6 months (n = 500), placebo for denosumab (n = 511), or oral alendronate 35 mg weekly (n = 251). All subjects received daily supplements of calcium and vitamin D. Main Outcome Measure: The primary endpoint was the 24-month incidence of new or worsening vertebral fracture for denosumab vs placebo. Results: Denosumab significantly reduced the risk of new or worsening vertebral fracture by 65.7%, with incidences of 3.6% in denosumab and 10.3% in placebo at 24 months (hazard ratio 0.343; 95% confidence interval 0.194–0.606, P = .0001). No apparent difference in adverse events was found between denosumab and placebo during the first 24 months of the study. Conclusion: These results provide evidence of the efficacy and safety of denosumab 60 mg sc every 6 months in Japanese subjects with osteoporosis. PMID:24646104

    Objective: For new evidence of aggressive lipid lowering treatment with statins in Japanese hypercholesterolemic patients, we performed an open-label, randomized, parallel-group comparative study to assess the effect of rosuvastatin 5 mg and atorvastatin 10 mg on plasma lipids. Methods: A total of 900 patients in whom the target control levels of LDL-cholesterol (LDL-C) set by the Japan Atherosclerosis Society Guidelines (JASGL2007) had not been achieved were randomly assigned to receive rosuvastatin 5 mg / day (n = 450) or atorvastatin 10 mg / day (n = 450) for 8 weeks. The primary endpoint was the percent change of LDL-C at week 8. Results: LDL-C was lowered by −44.5% (from 170.2 to 93.3 mg / dL) in the rosuvastatin group and −41.6% (from 169.5 to 97.9 mg / dL) in the atorvastatin group, at week 8 (P = 0.002 vs. atorvastatin). LDL-C / HDL-C ratio was lowered by −47.6% (from 3.01 to 1.56) and −43.5 % (from 2.96 to 1.66), respectively, at week 8 (P < 0.001 vs. atorvastatin). The changes in HDL-C, ApoB, ApoA-1, and ApoB / ApoA-1 ratio showed significant improvement in the rosuvastatin group than in the atorvastatin group. Adverse events were observed comparably between the rosuvastatin group (121 events) and the atorvastatin group (104 events). None of these events had adverse clinical consequence. Both drugs were well tolerated. Conclusion: Rosuvastatin 5 mg produced significantly greater reduction in LDL-C and beneficial effect on other lipid parameters than atorvastatin 10 mg, and was also well tolerated. PMID:23555376

    New oral anticoagulants (NOACs) are now clinically available. However, few studies have demonstrated which patients with non-valvular atrial fibrillation (NVAF) actually receive NOACs in a clinical setting. We analyzed 182 NVAF patients who received oral anticoagulants. Clinical backgrounds and the risk of stroke, systemic embolism, and bleeding associated with oral anticoagulants were investigated. Seventy-three (40 %) patients were treated with NOACs and 109 (60 %) patients were treated with warfarin. A significantly lower mean number of bleeding risk factors was observed among the patients treated with NOACs than among those treated with warfarin (P = 0.010). Of the bleeding risk factors, NOACs were significantly less frequently prescribed in patients with a bleeding history and elderly subjects (>65 years) than in those who received warfarin (P < 0.001 and P = 0.029). A multivariate logistic regression analysis revealed that CHF and bleeding history were independently and significantly associated with the administration of NOACs (P = 0.047 and P = 0.003). The rate of a history of intracranial hemorrhage was comparable between the patients treated with NOACs and those treated with warfarin (P = 1.000). Significantly lower rates of a history of gastrointestinal and other minor bleeding were observed in the patients who received NOACs versus those who received warfarin (P = 0.001 and P = 0.026). NOACs were less frequently prescribed in patients with a history of bleeding, especially those with a history of gastrointestinal bleeding in a clinical setting. PMID:26022376

    Patient data is central to a Clinical Information System (CIS). The organization of the data in a patient database is essential to the functioning of the system. If the CIS contains a medical decision support component, further requirements are imposed on the database. It must be capable of accurately representing a broad range of clinical information in coded form, and be organized for efficient retrievals by patient, time, and type of clinical term. This paper presents a generalized schema for a clinical patient database within the relational database model. The general design makes it possible to represent diverse clinical data in a standard structure and to organize the data so that it is densely clustered by patient and time.

    An increasing number of patients with lung cancer are undergoing outpatient chemotherapy.It is very important to retain the quality of life (QOL) of these patients.Japanese traditional medicine, TJ-48, has been reported to improve the QOL of patients with advanced cancer. However, the effect of TJ-48 in patients with lung cancer undergoing outpatient chemotherapy is unknown. The present study was conducted to investigate the factors influencing the QOL of these patients. We used "The QOL questionnaire for cancer patients treated with anticancer drugs" (QOL-ACD) with 16 patients with non-small cell lung cancer. The medical factors related to the overall QOL scores and other variables indicating "activity," "physical condition, "psychological condition,"social relationships," "psychological condition," and "face scale" were analyzed. Significant improvement was observed in the total QOL score, mainly owing to the improvement in the patients "physical condition." PMID:27067849

    We reviewed ten patients with seronegative spondylarthropathy (SNSA), who all fulfilled the European Spondylarthropathy Study Group criteria for spondylarthropathy (SpA); seven patients also met the Amor criteria for SpA. Seronegative spondylarthropathy was not a uniform syndrome but rather a wide spectrum of complex disease with characteristics of sacroiliitis and enthesopathy. The most frequent symptom at diagnosis of SNSA was inflammatory low back pain, followed by asymmetric oligoarthralgia and Achilles tendonitis and/or plantar fasciitis. Systemic complications were revealed as eye and skin involvement. Imaging methods including pelvic radiography, scintigraphy, and computed tomography scanning were useful in detecting spondylarthropathic changes, which were characteristic of SNSA. Human leukocyte antigen (HLA) typing showed various patterns among patients, in which HLA-B27 was positive in three patients with ankylosing spondylitis. HLA-B51, which is a well-known genetic factor associated with Behçet's disease (BD), was positive in two patients who were apparently distinct from BD. Two patients with palmoplantar pustulosis showed symptoms and signs characteristic of SNSA. Although we have few SNSA patients in the present study, we would like to propose that HLA-B51 positive SpA would be considered as a subset of SNSA, and that pustulotic SpA also would be classified as a member of SNSA. This led us to suggest the possibility to change the concept of SNSA proposed by Moll et al. The optimal treatment remains to be defined, but sulfasalazine was effectively used with almost all patients in combination with nonsteroidal anti-inflammatory drugs. PMID:17029088

    Background: Patients with schizophrenia reportedly have a high prevalence of obesity. One of the reasons is a poor choice of diet. The goal of this study was to clarify characteristics of the dietary intake across the strata of the body mass index (BMI) and to compare the general population and patients with schizophrenia in Japan. Methods: This is a cross-sectional study of 51 patients with schizophrenia residing in rural areas in 2011. Anthropometric indices (of height, weight, body mass index) were measured at the commencement of the survey. Intakes of energy, protein, fat, carbohydrate, calcium, phosphorus, vitamins, total fiber, and salt were noted through a 3-day dietary recording. The nutrient intake was estimated using Excel add-in software (Excel Eiyou-kun Ver. 6.0, Kenpakusha Co., Ltd.). Patients were divided into two groups: those with a BMI ≥25 kg/m2 and with a BMI <25 kg/m2, and the differences in their nutrition intake were analyzed. To compare these patients with the general population, the results of the National Health and Nutrition Survey, 2010 (NHNS) were used (the NHNS group). For statistical analysis, an unpaired t-test was performed with P < 0.05. Results: Patients with a BMI ≥25 kg/m2 had the higher intakes than those with a BMI <25 kg/m2 of energy, fat and phosphorus and salt. Patients with schizophrenia showed higher intakes of energy, carbohydrate, fat, calcium, phosphorus and salt than the NHNS group. Conclusion: The characteristics of the dietary intake in patients with schizophrenia were suggested the food constitution that is likely to increase the body weight. PMID:26284204

    Netherton syndrome (NS) is a congenital ichthyosiform dermatosis caused by serine protease inhibitor Kazal-type 5 (SPINK5) mutations. Tissue kallikreins (KLKs) and lymphoepithelial Kazal-type-related inhibitor (LEKTI) (SPINK5 product) may contribute to the balance of serine proteases/inhibitors in skin and influence skin barrier function and desquamation. SPINK5 mutations, causing NS, lead to truncated LEKTI; each NS patient possesses LEKTI of a different length, depending on the location of mutations. This study aims to elucidate genotype/phenotype correlations in Japanese NS patients and to characterize the functions of each LEKTI domain. Since we were unable to demonstrate truncated proteins in tissue from patients with NS, we used recombinant protein to test the hypothesis that the length of LEKTI correlated with protease inhibitory activity. Genotype/phenotype correlations were observed with cutaneous severity, growth retardation, skin infection, stratum corneum (SC) protease activities, and KLK levels in the SC. Predominant inhibition by LEKTI domains against overall SC protease activities was trypsin-like (Phe-Ser-Arg-) activity by LEKTI domains 6-12, plasmin- and trypsin-like (Pro-Phe-Arg-) activities by domains 12-15, chymotrypsin-like activity by all domains, and furin-like activity by none. KLK levels were significantly elevated in the SC and serum of NS patients. These data link LEKTI domain deficiency and clinical manifestations in NS patients and pinpoints to possibilities for targeted therapeutic interventions. PMID:17989726

    We evaluated the clinicopathologic findings and surgical results of 140 patients with thoracic esophageal cancer treated at Shinshu University, Japan (Shinshu group), and compared them with those from 1164 patients treated at Hebei Medical College, China (Hebei group) to determine if the two groups showed any differences. The Shinshu group had significantly higher incidences of elderly patients (>70 years of age), male patients, and tumors located at the lower esophagus (p < 0.01). In the Hebei group, although the depth of tumor invasion was more advanced, the incidence of nodal metastasis was significantly lower (p < 0.01). Operative death and postoperative complications were more frequent in the Shinshu group. Comparison of the postoperative survival curves revealed significantly longer survival of patients with pT2 or pT3 tumor in the Hebei group (p < 0.01), but there were no significant differences between the two groups when the lesions were classified by pTNM stage. This study demonstrated several differences between the patients in the two areas in regard to the clinicopathologic characteristics of thoracic esophageal cancer. The most important characteristic of the esophageal cancer in the Hebei group appears to be the low incidence of nodal metastasis. PMID:8661840

    Depression has been reported to be more prevalent among diabetic patients than non-diabetic individuals. Although depression and diabetes are causally and bi-directionally related, the influence of food intake frequency on depressive symptoms in diabetic patients has not been fully evaluated. This cross-sectional study analyzed data obtained from 89 patients with type 2 diabetes who completed self-administered questionnaires regarding food intake frequency, diabetic variables, physical activity and depressive states. The prevalence of a “definite” depressive state was 16.9%. The duration of diabetes, hemoglobin A1c levels, diabetic microvascular complications and physical activity levels were similar between depressed and non-depressed patients. Daily intakes of total lipids, n-6 polyunsaturated fatty acids and lipid energy ratios were significantly lower, and the carbohydrate energy ratio was significantly higher in depressed than in non-depressed patients. Coffee consumption was inversely associated with depressive symptoms, but no significant association was found between tea or green tea consumption and depressive symptoms. The logistic regression analysis showed that coffee consumption was an independent predictor of non-depressed status in diabetic patients. This might be due to biologically active compounds containing in coffee other than caffeine. PMID:25320461

    Several studies have noted that multi-impulsive bulimia nervosa tends to be refractory to treatment. However, it is not known whether these impulsivities are an expression of more fundamental psychopathology or simply the consequence of chaotic eating behaviors. Studies of the temporal relationship between the onset of eating disorder and the occurrence of impulsive behaviors will facilitate a better understanding of these issues. Subjects consisted of 60 patients with anorexia nervosa restricting type (AN-R), 62 patients with anorexia nervosa binge-eating/purging type (AN-BP), 114 patients with bulimia nervosa purging type (BN) and 66 control subjects. Impulsive behaviors and childhood traumatic experiences were assessed by self-report questionnaire. Multi-impulsivity (defined by at least three of the following: heavy regular alcohol drinking; suicide attempt; self-mutilation; repeated shoplifting of items other than food; sexual relationships with persons not well known to the subject) was found in 2% of AN-R, 11% of AN-BP, 18% of BN and 2% of control subjects. Eighty percent of BN patients with multi-impulsivity had a history of suicide attempts or self-mutilation history prior to the onset of bulimia nervosa. In BN patients, there tended to be a relationship between childhood parental loss or borderline personality disorder and multi-impulsivity. In conclusion, primary impulsivity (chronological prior occurrence of impulsive behaviors) does exist even in a very different culture, although the number of patients of this type is very limited.

    In LUX-Lung 3, afatinib significantly improved progression-free survival (PFS) versus cisplatin/pemetrexed in EGFR mutation-positive lung adenocarcinoma patients and overall survival (OS) in Del19 patients. Preplanned analyses in Japanese patients from LUX-Lung 3 were performed. Patients were randomized 2:1 to afatinib or cisplatin/pemetrexed, stratified by mutation type (Del19/L858R/Other). Primary endpoint was PFS (independent review). Secondary endpoints included OS, objective response, and safety. Median PFS (data cut-off: February 2012) for afatinib versus cisplatin/pemetrexed was 13.8 vs 6.9 months (hazard ratio [HR], 0.38; 95% confidence interval [CI], 0.20-0.70; P = 0.0014) in all Japanese patients (N = 83), with more pronounced improvements in those with common mutations (Del19/L858R; HR, 0.28; 95% CI, 0.15-0.52; P < 0.0001) and Del19 mutations (HR, 0.16; 95% CI, 0.06-0.39; P < 0.0001). PFS was also improved in L858R patients (HR, 0.50; 95% CI, 0.20-1.25; P = 0.1309). Median OS (data cut-off: November 2013) with afatinib versus cisplatin/pemetrexed was 46.9 vs 35.8 months (HR, 0.75; 95% CI, 0.40-1.43; P = 0.3791) in all Japanese patients, with greater benefit in patients with common mutations (HR, 0.57; 95% CI, 0.29-1.12; P = 0.0966) and Del19 mutations (HR, 0.34; 95% CI, 0.13-0.87; P = 0.0181); OS was not significantly different in L858R patients (HR, 1.13; 95% CI, 0.40-3.21; P = 0.8212). Following study treatment discontinuation, most patients (93.5%) received subsequent anticancer therapy. The most common treatment-related adverse events were diarrhea, rash/acne, nail effects and stomatitis with afatinib and nausea, decreased appetite, neutropenia, and leukopenia with cisplatin/pemetrexed. Afatinib significantly improved PFS versus cisplatin/pemetrexed in Japanese EGFR mutation-positive lung adenocarcinoma patients and OS in Del19 but not L858R patients (www.clinicaltrials.gov; NCT00949650).

    A questionnaire survey was done to examine the associations between the dimensions of safety climate and the nurses' motivation toward patient safety. Excluding nursing directors, a total of 371 full-time female Japanese nurses (registered nurses and licensed practical nurses) working in 6 hospitals of fewer than 250 beds were analyzed. The average age was 35.6 yr (range, 20-69). For the safety climate, factor analysis (the principal factor method and promax rotation) was performed, and factors with an eigenvalue of>or=1 were extracted. Seven dimensions were extracted by factor analysis as follows: "Opportunities for nursing education", "Reporting", "Fatigue reduction", "Superiors' attitudes", "Nursing conditions", "Communications with physicians", and "Relationships among nurses". We subsequently examined the associations between the dimensions of the safety climate and "Nurses' motivation to prevent mistakes". Multiple linear regression analysis showed that "Nurses' motivation to prevent mistakes" was significantly associated with "Reporting", "Nursing conditions", and "Communications with physicians". It is necessary to improve the reporting system in hospitals. It is also necessary to improve on reducing improper communications with physicians. And appropriate nursing conditions must be actualized and maintained. PMID:19218760

    Recent studies have revealed the evidence for the significance of SV40 genome in human malignancies. In this paper, the presence of SV40-like sequences was investigated in 54 Japanese osteosarcomas in which mutations of the retinoblastoma (Rb), p53, MDM2, and CDK4 genes had been already analysed. Using polymerase chain reaction and Southern hybridization, SV40-like sequences were detected in 25 cases (46.3%). In most cases, only a part of SV40 genome was detected, and the regulatory region containing enhancer sequences was most frequently found (21/54, 38.9%). There was no apparent relationship between the presence of SV40-like sequences and tumour suppressor genes mutations in each tumour. The SV40-like sequences were also detected in peripheral blood cells of substantial proportion of the patients (43.3%), whereas the incidence was much lower (4.7%) in normal healthy controls. This difference is statistically highly significant (P< 0.0001), suggesting that the presence of SV40-like sequences, even if only a part, may play some roles to predispose individuals to osteosarcoma. © 2000 Cancer Research Campaign PMID:10817503

    Background Agitated behaviors are frequently observed in patients with dementia and can cause severe distress to caregivers. However, little evidence of the efficacy of nonpharmacological interventions for agitated behaviors exists for patients with dementia. The present pilot study aimed to evaluate a behavioral management program developed by the Seattle Protocols for patients with agitated behaviors in Japan. Methods Eighteen patients with dementia (Alzheimer’s disease, n = 14; dementia with Lewy bodies, n = 4) participated in an open study testing the effectiveness of a behavioral management program. The intervention consisted of 20 sessions over the course of 3 months. The primary outcomes were severity of agitation in dementia, as measured using the Agitated Behavior in Dementia scale (ABID) and the Cohen-Mansfield Agitation Inventory (CMAI). Results The behavioral management program resulted in significant reductions in total scores on both the ABID and CMAI. Although both physically agitated and verbally agitated behavior scores on the ABID improved significantly, symptoms of psychosis did not improve after the intervention. Conclusion The behavioral management technique may be beneficial to distressed caregivers of patients with dementia. In the future, a well designed study to develop the behavioral management program more fully is needed. PMID:23293522

  1. Dietary patterns are associated with obesity in Japanese patients with schizophrenia

    PubMed Central

    2014-01-01

    Background Obesity among patients with schizophrenia is a growing concern because being overweight is widely regarded as a major risk factor for cardiovascular disease and premature death. Dietary patterns have been suggested as one modifiable factor that may play a role in development of obesity. The objective of this study was to examine the association between dietary patterns and obesity among patients with schizophrenia in Japan. Methods We recruited patients (n = 338) aged 44.0 ± 13.2 (mean ± SD) years with a DSM-IV diagnosis of schizophrenia who were admitted to four psychiatric hospitals using a cross-sectional design. Diet was assessed with a validated brief-type self-administered diet history questionnaire (BDHQ). Dietary patterns from 52 predefined food groups were extracted by principal component analysis. Results A total of 61 subjects (18.0%) were classified as obese. Three dietary patterns were identified: the healthy dietary pattern, the processed food dietary pattern, and the alcohol and accompanying dietary patterns. After adjusting for age and gender, patients within the high tertile of each healthy dietary pattern (OR = 0.29, 95% CI = 0.13 to 0.62) and processed food dietary pattern (OR = 0.44, 95% CI = 0.22 to 0.89) had a significantly lower risk for obesity compared with low tertile of dietary pattern. Conclusions Our findings suggest that dietary patterns, including higher intake of protein, fat, n-3 polyunsaturated fatty acids, n-6 polyunsaturated fatty acids, and vitamins, may be related to a decreased prevalence of obesity within patients with schizophrenia. Future longitudinal research exploring dietary patterns and obesity among patients with schizophrenia is warranted. PMID:24947974

    This article addresses why in the current context of driving toward improved value, physician groups ought to consider developing a patient safety evaluation system and reporting to a patient safety organization. The fundamental challenge to physicians to succeed in the future is to clinically integrate within their own practices, standardizing to the evidence base, and measuring their performance. In addition, it is increasingly clear that the physician office practice is a source of patient safety issues. The Patient Safety and Quality Improvement Act provides two powerful protections for data that will support and bolster clinical integration and patient safety. The protections and how to deploy them are presented. PMID:24873122

    Forty nine patients with 63 tumours were treated with the Chongqing Haifu knife, as an adjunct to intra-arterial chemoinfusion. Treatment targets included breast (20 lesions), liver (16), bone (8), lymph-node (6), soft tissue (4), lung and pleura (4), pancreas (2), kidney (2) and adrenal gland (1). Follow-up contrast MRI was performed at 3 weeks to assess the effects of HIFU ablation. All cases completed the planned treatment. Of 25 lesions treated with the intention of complete tumour ablation, complete necrosis was obtained in 19 lesions (76%) including 4 secondary success cases. Among 32 lesions having partial and palliative treatment, tumour size was decreased in 6 lesions (21%), and good pain control was obtained in 6 out of 7 patients (86%). Skin injury was the most common complication after HIFU (16%), and was mostly a superficial dermal burn that did not necessitate any treatment. However, there was one patient with deep skin injury at an operation scar which resulted in skin perforation. Other adverse events included soft tissue swelling, prolonged fever, anorexia, persistent pain, shortness of the breath, sacroiliac joint fracture and prolonged diarrhoea. In our limited experience, superficial lesions (e.g. breast cancer, bone, soft tissue, lymph-node and pleural metastasis) appear to be good candidates for HIFU treatment. There appears to be a role for the HIFU knife in pain control for patients with bone metastasis and pancreatic cancer.

    We evaluated the efficacy and tolerability of Gosha-jinki-gan (GJG; 濟生腎氣丸 jì shēng shèn qì wán) in 30 cases of nocturia (夜尿 yè niào) unresponsive to α1-blockers or antimuscarinic drugs. All patients received GJG extract powder (2.5 g) three times a day for 12 weeks as an add-on therapy to α1-blockers or antimuscarinic drugs. Subjective outcomes assessed by the International Prostate Symptom Score—quality of life, and the benign prostatic hyperplasia impact index and objective outcomes assessed by urinary frequency and the urine production rate at night showed significant improvement after treatment. Moreover, other objective outcomes assessed by maximum flow rates, postvoid residual, serum human atrial natriuretic peptide levels, and urinary 8-hydroxy-2′-deoxyguanosine levels did not change. Adverse events were observed in 10% of cases; however, these events were mild. GJG appears to be a safe and effective potential therapeutic alternative for patients with nocturia unresponsive to α1-blockers or antimuscarinic drugs. Further clinical investigations are required to elucidate the precise pathophysiologic mechanisms of GJG in nocturia. PMID:26870690

    Summary Background and objectives Control of serum concentrations of calcium (Ca), phosphorus (P), and parathyroid hormone (PTH) is essential for management of secondary hyperparathyroidism (SHPT). Design, setting, participants, & measurements This is a planned interim analysis of a longitudinal cohort study. The settings are dialysis facilities in Japan. Eligible patients comprise all those who were receiving hemodialysis at one of 86 participating facilities and who have SHPT. Using data from a random sample (n = 3276) of the participants from January 2008 through June 2009, we measured changes in the percentages of patients who were within the national guideline–specified target ranges of Ca (8.4 to 10 mg/dl), P (3.5 to 6.0 mg/dl), and intact PTH (iPTH) (60 to 180 pg/ml), and changes in prescriptions of drugs targeting SHPT. We used regression models to identify factors affecting the achievement of the guideline-specified targets. Results There were no notable changes in the percentage of patients who were within the guideline for Ca, P, or both. The percentage who were within the iPTH guideline increased from 14.5% to 43.3% (P < 0.001). There were no remarkable changes in the percentage of patients receiving vitamin D or phosphate binders. The percentage who received cinacalcet increased from 0% to 29%. Prescription of cinacalcet was associated with improvement or target-achievement for iPTH and for Ca by 16.8 percentage points (95% CI: 8.1 to 17.0) and by 12.6 percentage points (13.7 to 19.9), respectively. Conclusions In the routine care of hemodialysis patients, increasing use of cinacalcet was associated with better control of SHPT. PMID:21836149

    Dual antiplatelet therapy is empirically recommended following transcatheter aortic valve implantation (TAVI). The aims of the present study were to analyze the effect of clopidogrel on platelet function and to determine the relative contribution of each CYP2C19 loss-of-function genotype undergoing TAVI.Thirty-two patients undergoing TAVI and with clopidogrel treatment were studied. All patients were treated with an Edwards SapienXT valve. Platelet reactivity was measured by the VerifyNow P2Y12 point-of-care assay at 7 days and 30 days after the procedure and a cutoff value of 95 PRU was used to identify a hyper-response of platelet reactivity. The Spartan RX(TM) sample-to-result point-of-care DNA testing system was used to identify CYP2C19 loss-of-function genotypes. Hyper-response of platelet reactivity was identified in 11 (34.3%) patients, although 24 (80%) were carriers of at least one CYP2C19 reduced-function allele. The PRU values did not change significantly from 7 days to 30 days after TAVI (136.7 ± 73.4 versus 150.4 ± 83.2, P = 0.13). The incidences of life-threatening bleeding, minor bleeding, and transfusion were significantly higher among the hyper-response of platelet reactivity group (27.3% versus 0%, P = 0.03, 36.4% versus 4.8%, P = 0.04, 81.8% versus 42.9%, P = 0.04, respectively).A hyper-response to clopidogrel was observed in one-third of patients undergoing TAVI and was related to bleeding events, even though 80% of the patients were carriers of the CYP2C19 reduced-function allele.

    The incidence of non-alcoholic fatty liver disease (NAFLD) is increasing in Western and Asian countries, including Japan. NAFLD includes the condition of non-alcoholic steatohepatitis, which can progress to end-stage liver disease. Weight reduction based on basal energy expenditure (BEE) is considered to be the only established treatment for patients with NAFLD. However, a formula that is suitable for predicting BEE in Japanese patients with NAFLD remains to be determined. We enrolled 77 Japanese patients who were diagnosed with NAFLD according to histological findings. Their BEE was measured (mBEE) by indirect calorimetry. Physical findings, laboratory data and their predicted BEE (pBEE) values were compared with the mBEE values. All pBEE values were evaluated as a root mean squared error (RMSE) and an accurate estimation. The mBEE values correlated with the patient's weight, skeletal muscle mass, and age. Most of predictive formulae overestimated BEE in NAFLD patients in the present study. In contrast, the Kyoto equation provided an accurate prediction. Most prediction formulae included body weight as a reference of the skeletal muscle mass and were established using data from a healthy study population. However, differences in muscle mass exist among different races, and body composition differs between healthy individuals and those with high BMIs. The improved accuracy of the Kyoto equation is likely due to the similar backgrounds of the patients in the present study. The Kyoto equation is the most suitable formula for estimating BEE in Japanese patients with NAFLD. PMID:27264095

    The clinical phenotypes of patients with Bartter syndrome type III sometimes closely resemble those of Gitelman syndrome. We report a patient with mild, adult-onset symptoms, such as muscular weakness and fatigue, who showed hypokalemic metabolic alkalosis, elevated renin–aldosterone levels with normal blood pressure, hypocalciuria and hypomagnesemia. She was also suffering from chondrocalcinosis. A diuretic test with furosemide and thiazide showed a good response to furosemide, but little response to thiazide. Although the clinical findings and diuretic tests predicted that the patient had Gitelman syndrome, genetic analysis found no mutation in SLC12A3. However, a novel missense mutation, p.L647F in CLCNKB, which is located in the CBS domain at the C-terminus of ClC-Kb, was discovered. Therefore, gene analyses of CLCNKB and SLC12A3 might be necessary to elucidate the precise etiology of the salt-losing tubulopathies regardless of the results of diuretic tests. PMID:25606418

    The biofield breast examination (BBE) is a new, noninvasive and cost-effective method for diagnosing breast lesions currently undergoing multicenter evaluation in the USA and Europe. The test analyzes subtle differences in electrical potential caused by dysregulated epithelial proliferation. This report summarizes a prospective evaluation of BBE in a population of 101 patients with suspicious breast lesions scheduled either for open surgical biopsy or fine needle aspiration biopsy. Of the 101 patients included in the study, 49 were found to have a breast malignancy and 52 were found to have a benign breast lesion. BBE correctly identified 44 of 49 biopsy-proven cancers (sensitivity=90%) and correctly indicated no cancer in 31 of 52 biopsy-proven benign cases (specificity=60%). Sensitivity increased to 95% for cancers less than 2.5 cm in size. These results indicate that BBE may be an effective adjunctive test to help to resolve abnormalities discovered by physical examination or other screening methods. PMID:8957069

    Providing a clean, comfortable bed and positioning a patient in the optimum posture for prevention of complications and to enable maximum independence are fundamental nursing skills. Bed-making is a daily routine that requires practical and technical skills. Selecting the correct posture for a patient in bed or in a chair is essential for physiological functioning and recovery. In this article bed-making is described, as are positioning and re-positioning in relation to patients in bed, armchairs and wheelchairs. Infection control and moving and handling issues are also considered. PMID:17505378

    Therapeutic advances in systemic lupus erythematosus (SLE) are greatly needed. Despite advances in our knowledge of pathogenesis of the disease and targets, treatment remains a significant challenge. Finding effective and relatively safe medications remains one of the top priorities. SLE significantly impairs quality of life (QoL), and patient-reported outcomes (PROs) measure a unique aspect of the disease not captured by disease activity. Inclusion of PRO measurements is encouraged in SLE clinical trials, as they allow capturing benefits of a proposed intervention in language patients can relate to and in areas deemed pertinent and important to and by patients. Availability of patient-reported and patient-centric clinical trials data may facilitate patients in informed and shared decision making, and allow for comparative cost-effectiveness evaluation for future resource allocation and reimbursements. Herein we review clinical trials with biologic therapies wherein PRO tools were included in the study design. PMID:27497256

    In 1970, a Japanese group reported the first use of endoscopic retrograde cholangiopancreatography (ERCP), which is now carried out worldwide. Selective bile duct cannulation is a mandatory technique for diagnostic and therapeutic ERCP. Development of the endoscope and other devices has contributed to the extended use of ERCP, which has become a basic procedure to diagnose and treat pancreaticobiliary diseases. Various techniques related to selective bile duct cannulation have been widely applied. Although the classical contrast medium injection cannulation technique remains valuable, use of wire-guided cannulation has expanded since the early 2000s, and the technique is now widely carried out in the USA and Europe. Endoscopists must pay particular attention to a patient's condition and make an attendant choice about the most effective technique for selective bile duct cannulation. Some techniques have the potential to shorten procedure time and reduce the incidence of adverse events, particularly post-ERCP pancreatitis. However, a great deal of experience is required and endoscopists must be skilled in a variety of techniques. Although the development of the transpapillary biliary cannulation approach is remarkable, it is important to note that, to date, there have been no reports of transpapillary cannulation preventing post-ERCP pancreatitis. In the present article, selective bile duct cannulation techniques in the context of recent Japanese randomized controlled trials and cases of precut sphincterotomy are reviewed and discussed.

    Objective. The clinical factors associated with sperm DNA fragmentation (SDF) were investigated in male patients with infertility. Materials and Methods. Fifty-four ejaculates from infertile Japanese males were used. Thirty-three and twenty-one were from the patients with varicoceles and idiopathic causes of infertility, respectively. We performed blood tests, including the serum sex hormone levels, and conventional and computer-assisted semen analyses. The sperm nuclear vacuolization (SNV) was evaluated using a high-magnification microscope. The SDF was evaluated using the sperm chromatin dispersion test (SCDt) to determine the SDF index (SDFI). The SDFI was compared with semen parameters and other clinical variables, including lifestyle factors. Results. The SDFI was 41.3 ± 22.2% (mean ± standard deviation) and did not depend on the cause of infertility. Chronic alcohol use increased the SDFI to 49.6 ± 23.3% compared with 33.9 ± 18.0% in nondrinkers. The SDFI was related to adverse conventional semen parameters and sperm motion characteristics and correlated with the serum FSH level. The SNV showed a tendency to increase with the SDFI. The multivariate analysis revealed that the sperm progressive motility and chronic alcohol use were significant predictors of the SDF. Conclusion. The SCDt should be offered to chronic alcohol users and those with decreased sperm progressive motility. PMID:25165747

    Objective Bromocriptine mesylate (BRC), a dopamine D2 receptor agonist has been shown to confer neuroprotection, sustained motor function and slowed disease progression in mouse models of amyotrophic lateral sclerosis (ALS) Here we report a first in human trial in ALS. Design A multicenter, Riluzole add-on, randomized, double-blind, placebo controlled 102-week extension BRC clinical trial. Methods The trial was conducted between January 2009 and March 2012 on 36 Japanese ALS patients. A 12-week treatment with Riluzole observational period was followed by combined treatment (Riluzole + BRC; n = 29 or Riluzole + placebo; n = 7). The dosing commenced at 1.25 mg/day increasing in steps at two weeks intervals to a maximum of 15 mg/day. The efficacy of BRC was evaluated by comparing BRC and placebo groups upon completion of stepwise dosing at 14 weeks 2 points (1st endpoint) and upon completion or discontinuation of the study (2nd endpoint) of the dosing. Results Statistics analyses revealed a marginal BRC treatment efficacy with P≦20%to placebo by 1st and 2nd endpoint analysis. In the 1st endpoint analysis, BRC group was significantly effective on the scores of ALSAQ40-communicaton (P = 1.2%), eating and drinking (P = 2.2%), ALSFRS-R total (P = 17.6%), grip strength (P = 19.8%) compared to the placebo group. In the 2nd endpoint analysis, differences between the scores of Limb Norris Scale (P = 18.3%), ALSAQ40-communication (P = 11.9%), eating and drinking (P = 13.6%), and neck forward-bent test (P = 15.4%) of BRC group were detected between the two groups. There was no significant difference between the treatment groups for adverse events or serious drug reactions incidence. Conclusions BRC sustains motoneuronal function at least in part through BRC treatment. Further analysis involving a Phase 2b or 3 clinical trial is required but BRC currently shows promise for ALS treatment. Trial Registration UMIN Clinical Trials UMIN000008527 PMID:26910108

    Although clinic environments are a primary location for exchanging information with clinicians, patients experience these spaces as harsh environments to access, use, exchange, and manage information. In this paper, we present results from an ethnographic-inspired study of breast cancer patients actively interacting with information in clinic environments. Through observations and interviews, we observed information interactions in awkward physical positions; inefficient use of existing clinical space; separation of patients from their information and lack of support for collaborative document viewing. These factors compromised patients’ abilities to manage their information work when they experienced bursts of information exchange, lack of advance information, fragmented attention, and heightened stress in clinic environments. To overcome these challenges, we identify formative strategies to focus attention, encourage collaboration, and improve communication in clinical settings. PMID:21654895

    A critical mass of Internet users is leading to a wide diffusion of electronic communications within medical practice. Unless implemented with substantial forethought, these new technological linkages could disturb delicate balances in the doctor-patient relationship, threaten the privacy of medical information, widen social disparity in health outcomes, and even function as barriers to access. The American Medical Informatics Association (AMIA) recently published recommendations to guide computer-based communications between clinicians and patients. This paper describes the motivations for and the design of HealthConnect, a web-based patient-doctor communications tool currently in use at Children's Hospital, Boston. Structural and process-oriented features of HealthConnect, as they relate to promotion of adherence with the Guidelines, are discussed. PMID:10566480

    This paper describes a large case study that explores the applicability of ontology reasoning to problems in the medical domain. We investigate whether it is possible to use such reasoning to automate common clinical tasks that are currently labor intensive and error prone, and focus our case study on improving cohort selection for clinical trials. An obstacle to automating such clinical tasks is the need to bridge the semantic gulf between raw patient data, such as laboratory tests or specific medications, and the way a clinician interprets this data. Our key insight is that matching patients to clinical trials can be formulated as a problem of semantic retrieval. We describe the technical challenges to building a realistic case study, which include problems related to scalability, the integration of large ontologies, and dealing with noisy, inconsistent data. Our solution is based on the SNOMED CT® ontology, and scales to one year of patient records (approx. 240,000 patients).

    To enhance patient safety from falls, many hospital information systems have been implemented to collect clinical data from the bedside and have used the information to improve fall prevention care. However, most of them use administrative data not clinical nursing data. This necessitated the development of a web-based Nursing Practice and Research Information Management System (NPRIMS) that processes clinical nursing data to measure nurses' delivery of fall prevention care and its impact on patient outcomes. This pilot study developed computer algorithms based on a falls prevention protocol and programmed the prototype NPRIMS. It successfully measured the performance of nursing care delivered and its impact on patient outcomes using clinical nursing data from the study site. Results of the study revealed that NPRIMS has the potential to pinpoint components of nursing processes that are in need of improvement for preventing patient from falls. PMID:27332171

    Cefotaxime is a new cephalosporin with a spectrum of activity which may make it appropriate for use in pediatric patients. In 33 infants and children, administration of cefotaxime resulted in cure or improvement in 97% of patients, with eradication of 94% of isolated pathogens. Toxicity was minimal. The disposition of cefotaxime in this age group was similar to that reported for adults, with an elimination half-life of approximately 1.5 h, a volume of distribution of 1 liter/kg, a total serum clearance of 10 ml/min per kg, and a renal clearance of 6 ml/min per kg.

    The present study examined the pharmacokinetics of biapenem during continuous venovenous hemodiafiltration (CVVHDF) and assessed the pharmacodynamic exposure, based on a pharmacokinetic model, to consider biapenem dosage adaptation in CVVHDF. Biapenem (300 mg) was administered by 2-h infusion to seven critically ill patients receiving CVVHDF. The flow rates were 60 ml/min for blood, 800 ml/h for filtrate, and 600 ml/h for dialysate. The drug concentrations in plasma and filtrate-dialysate were determined by high-performance liquid chromatography and analyzed pharmacokinetically. The sieving coefficient was 0.92 +/- 0.06 (mean +/- SD). The simulation curves, using a multicompartment model, were well fitted to the measurements in plasma and filtrate-dialysate. The clearance by CVVHDF and the clearance by non-CVVHDF routes were 1.29 +/- 0.08 and 6.14 +/- 1.89 l/h, respectively. The multicompartment model was used to assess the pharmacodynamic exposure (time above the minimum inhibitory concentration of 4 microg/ml) in plasma. When the total daily dose was 600 mg, the duration of time was greater at 300 mg every 12 h than at 600 mg every 24 h. The minimum dosages needed to achieve more than 30% of the dosing interval at filtrate-dialysate flow rates of 1.4, 2.8, and 5.6 l/h were 300 mg every 12 h, 600 mg every 12 h, and 600 mg every 12 h, respectively. These results suggested that low doses or increased dosing intervals should be avoided in patients receiving this renal replacement technique. Information on pharmacodynamic exposure obtained from this model may help us to determine the appropriate biapenem dosage for CVVHDF. Moreover, our pharmacokinetic model may be useful for further pharmacokinetic studies of biapenem. PMID:18297447

    Background/Aims This was a Phase 2 study (NCT02015793) to evaluate the pharmacokinetics, safety, and efficacy of adalimumab in Chinese patients with Crohn's disease (CD). Methods Thirty, adult Chinese patients with CD (CD Activity Index [CDAI] 220–450; high-sensitivity [hs]-C-reactive protein [CRP] ≥3 mg/L) received double-blind adalimumab 160/80 mg or 80/40 mg at weeks 0/2, followed by 40 mg at weeks 4 and 6. An open-label extension period occurred from weeks 8–26; patients received 40 mg adalimumab every other week. Serum adalimumab concentration and change from baseline in fecal calprotectin (FC) were measured during the double-blind period. Clinical remission (CDAI <150), response (decrease in CDAI ≥70 points from baseline), and change from baseline in hs-CRP were assessed through week 26. Nonresponder imputation was used for missing categorical data and last observation carried forward for missing hs-CRP/FC values. No formal hypothesis was tested. Adverse events were monitored. Results Mean adalimumab serum concentrations during the induction phase were 13.9–18.1 µg/mL (160/80 mg group) and 7.5−9.5 µg/mL (80/40 mg group). During the double-blind period, higher remission/response rates and greater reductions from baseline in hs-CRP and FC were observed with adalimumab 160/80 mg compared to that with 80/40 mg. Adverse event rates were similar among all treatment groups. Conclusions Adalimumab serum concentrations in Chinese patients with CD were comparable to those observed previously in Western and Japanese patients. Clinically meaningful remission rates and improvement in inflammatory markers were achieved with both dosing regimens; changes occurred rapidly with adalimumab 160/80 mg induction therapy. No new safety signals were reported. PMID:27175116

    Aldehyde dehydrogenase 2 (ALDH2) detoxifies aldehyde produced during ethanol metabolism and oxidative stress. A genetic defect in this enzyme is common in East Asians and determines alcohol consumption behaviors. We investigated the impact of genetically determined ALDH2 activity on diabetic microvascular and macrovascular complications in relation to drinking habits in Japanese patients with type 2 diabetes mellitus. An ALDH2 single-nucleotide polymorphism (rs671) was genotyped in 4,400 patients. Additionally, the relationship of clinical characteristics with ALDH2 activity (ALDH2 *1/*1 active enzyme activity vs. *1/*2 or *2/*2 inactive enzyme activity) and drinking habits (lifetime abstainers vs. former or current drinkers) was investigated cross-sectionally (n = 691 in *1/*1 abstainers, n = 1,315 in abstainers with *2, n = 1,711 in *1/*1 drinkers, n = 683 in drinkers with *2). The multiple logistic regression analysis for diabetic complications was adjusted for age, sex, current smoking habits, leisure-time physical activity, depressive symptoms, diabetes duration, body mass index, hemoglobin A1c, insulin use, high-density lipoprotein cholesterol, systolic blood pressure and renin-angiotensin system inhibitors use. Albuminuria prevalence was significantly lower in the drinkers with *2 than that of other groups (odds ratio [95% confidence interval (CI)]: *1/*1 abstainers as the referent, 0.94 [0.76-1.16] in abstainers with *2, 1.00 [0.80-1.26] in *1/*1 drinkers, 0.71 [0.54-0.93] in drinkers with *2). Retinal photocoagulation prevalence was also lower in drinkers with ALDH2 *2 than that of other groups. In contrast, myocardial infarction was significantly increased in ALDH2 *2 carriers compared with that in ALDH2 *1/*1 abstainers (odds ratio [95% CI]: *1/*1 abstainers as the referent, 2.63 [1.28-6.13] in abstainers with *2, 1.89 [0.89-4.51] in *1/*1 drinkers, 2.35 [1.06-5.79] in drinkers with *2).

    OBJECTIVE Cervical spondylotic myelopathy (CSM) is the most common cause of nontraumatic spinal cord impairment and disability in the world. Given that the Japanese Orthopaedic Association (JOA) score is the most frequently used outcome measure in clinical research and practice for treating patients with CSM, this review was undertaken to comprehensively and critically evaluate the psychometric properties of the JOA score. METHODS The authors identified studies (published in the period of January 1975 to November 2015) on the psychometric properties of the original, revised, and modified versions of the JOA score in Medline, PsycINFO, Excerpta Medica dataBASE (EMBASE), American College of Physicians Journal Club, and Cochrane Database of Systematic Reviews. Additional publications were captured in a secondary search of the bibliographies in both original research articles and literature reviews identified in the original search. The JOA scores were evaluated for item generation and reduction, internal consistency, reliability, validity, and responsiveness. This review included all those versions of the JOA score whose psychometric properties had been reported in at least 2 published studies. RESULTS The primary search strategy identified 59 studies, of which 9 fulfilled the inclusion and exclusion criteria. An additional 18 publications were captured in the secondary search and included in the analysis. The key findings from the 27 studies analyzed indicated the following: 1) the original JOA score (1975) was the source for the revised JOA score (1994) and 3 modified versions (1991, 1993, and 1999 JOA scores) reported or used in at least 2 published studies; 2) the revised and modified versions of the JOA score are markedly different from each other; 3) only the revised JOA score (1994) was validated with the original JOA score; and 4) the 1975 JOA score is the most appropriate instrument for assessing patients in Asian populations (especially from Japan) because

    Aldehyde dehydrogenase 2 (ALDH2) detoxifies aldehyde produced during ethanol metabolism and oxidative stress. A genetic defect in this enzyme is common in East Asians and determines alcohol consumption behaviors. We investigated the impact of genetically determined ALDH2 activity on diabetic microvascular and macrovascular complications in relation to drinking habits in Japanese patients with type 2 diabetes mellitus. An ALDH2 single-nucleotide polymorphism (rs671) was genotyped in 4,400 patients. Additionally, the relationship of clinical characteristics with ALDH2 activity (ALDH2 *1/*1 active enzyme activity vs. *1/*2 or *2/*2 inactive enzyme activity) and drinking habits (lifetime abstainers vs. former or current drinkers) was investigated cross-sectionally (n = 691 in *1/*1 abstainers, n = 1,315 in abstainers with *2, n = 1,711 in *1/*1 drinkers, n = 683 in drinkers with *2). The multiple logistic regression analysis for diabetic complications was adjusted for age, sex, current smoking habits, leisure-time physical activity, depressive symptoms, diabetes duration, body mass index, hemoglobin A1c, insulin use, high-density lipoprotein cholesterol, systolic blood pressure and renin-angiotensin system inhibitors use. Albuminuria prevalence was significantly lower in the drinkers with *2 than that of other groups (odds ratio [95% confidence interval (CI)]: *1/*1 abstainers as the referent, 0.94 [0.76–1.16] in abstainers with *2, 1.00 [0.80–1.26] in *1/*1 drinkers, 0.71 [0.54–0.93] in drinkers with *2). Retinal photocoagulation prevalence was also lower in drinkers with ALDH2 *2 than that of other groups. In contrast, myocardial infarction was significantly increased in ALDH2 *2 carriers compared with that in ALDH2 *1/*1 abstainers (odds ratio [95% CI]: *1/*1 abstainers as the referent, 2.63 [1.28–6.13] in abstainers with *2, 1.89 [0.89–4.51] in *1/*1 drinkers, 2.35 [1.06–5.79] in drinkers with *2). In summary, patients with type 2 diabetes and ALDH2 *2

    Abacavir/lamivudine (ABC/3TC) is a nucleoside reverse transcriptase inhibitor used for treating human immunodeficiency viral (HIV) infections. Hypersensitivity reactions such as skin eruptions caused by ABC are well-known, but rarely occur in Asians. Raltegravir (RAL) is an integrase strand transfer inhibitor, that is now increasingly, used for treating HIV infections because it has few adverse effects. This retrospective analysis assessed the efficacy and safety of combined ABC/3TC and RAL in both treatment-naïve and -experienced Japanese patients with HIV infections. In all 11 treatment-naïve patients (100%), virological suppression to undetectable level was achieved. Liver transaminases, renal function, and serum lipid profiles showed no exacerbations up to 48 weeks of treatment. In 12 patients who were switched from previous regimens to ABC/3TC and RAL, HIV viral load was undetectable in 11 patients (91.6%), but remained detectable in 1 patient with poor adherence. Major reasons for switching regimens to ABC/3TC and RAL were hyperlipidemia and nausea. After switching, these adverse effects improved, and no new adverse effects were observed. Despite the small number of participants in this study, the results support the combination of ABC/3TC and RAL as a possible treatment choice in Japanese individuals with HIV-infection.

    Dengue fever is a serious concern for Japanese people staying in Southeast Asia. In order to implement necessary prophylactic measures for dengue fever in this population, we investigated the characteristics of dengue fever among Japanese nationals living in Manila, Philippines. From 2012 to 2015, 175 Japanese expatriates were diagnosed with dengue fever at the medical clinic of the Japanese Association Manila, Inc. Most of the patients were employees of Japanese companies and their families and were long-term residents of Manila. Most patients were either <10 years or in their 30s to 40s. Two patients (1.1 %) were diagnosed with dengue hemorrhagic fever. No deaths due to dengue fever were reported. The reported number of patients with dengue fever has shown a decreasing trend: from 55 cases in 2012 to 53 in 2013, 31 in 2014, and 36 in 2015. The results of this survey could be useful for the development of effective dengue fever preventive measures such as health education and provision of information among not only Japanese but also other foreigners residing in endemic areas.

    Neurofibromatosis 1 (NF1) is a multisystem genetic disorder that primarily affects the skin (freckling and café-au-lait macules), nervous system (neurofibromas, optic gliomas, and learning disabilities), and skeletal system (pseudoarthroses). The interest in pharmacological intervention for patients with NF1 has grown in recent years. However, little is known about the attitudes and priorities of patients, families, and physicians regarding participation in clinical trials. We surveyed 74 adult patients or parents of patients with NF1 and 69 care providers participating in a neurofibromatosis clinic to assess their willingness to participate in clinical trials and their opinions about which conditions they thought were most important to treat. Both patients and care providers are willing to participate in clinical trials for NF1 and both groups rate malignant peripheral nerve sheath tumors as the most urgent for new treatments. There are concordant views among patients and physicians concerning clinical trials for NF1, and patients do not dismiss participation in placebo-controlled trials. Neuroscience nurses are poised to facilitate the research process from conception through implementation as they take the viewpoints of our study populations into consideration. PMID:19170300

    Sudden hearing loss may occur in rare cases of relapsing-remitting multiple sclerosis (RRMS). There have also been reports of idiopathic sudden sensorineural hearing loss (SNHL) in patients with neuromyelitis optica spectrum disorders (NMOSD), but the frequency of such cases is unclear. We conducted a retrospective analysis of the medical records of 173 consecutive patients with multiple sclerosis (MS) and 101 consecutive patients with NMOSD who tested positive for anti-aquaporin-4 antibodies in addition to 37 consecutive patients with clinically isolated syndromes (CIS) to investigate the frequency and onset timing of SNHL. SNHL was observed in six (3.5%) of the RRMS cases, one (1.0%) of the seropositive NMOSD cases, and three (8.1%) of the CIS cases. SNHL occurred ahead of onset in 4/6 MS patients and in all of 3 CIS patients. Patient with NMOSD exhibited SNHL 6years after the onset of NMOSD. Although SNHL is rare, these results suggest the risk of developing demyelinating lesions in the central nervous system and further conversion to MS in the future. PMID:27609270

    Numerous studies have documented that adolescents and young adults (AYAs) experience a significant cancer burden as well as significant cancer mortality compared with other age groups. The reasons for the disparate outcomes of AYAs and other age groups are not completely understood and are likely to be multifactorial, including a range of sociodemographic issues unique to these individuals as well as differences between adolescents, younger pediatric patients, and adults in the pharmacology of anticancer agents. Because adolescence is a period of transition from childhood to early adulthood, numerous physical, physiologic, cognitive, and behavioral changes occur during this time. In this review, we provide an overview of the unique developmental physiology of the adolescent and explain how these factors and the behavioral characteristics of adolescents may affect the pharmacology of anticancer agents in this patient population. Finally, we describe examples of studies that have assessed the relation between drug disposition and age, focusing on the AYA age group. PMID:20439647

    Objective The prevalence of type 2 diabetes is increasing rapidly in the young population. The clinical characteristics and risk factors for young type 2 diabetes patients with atherosclerosis are not fully explicated. The aim of the present study was to investigate various clinical and biochemical characteristics of young type 2 diabetic patients with atherosclerosis. Design and Methods This was a cross-sectional study. The study involved 2199 hospitalized patients with type 2 diabetes. The young patients were classified into the atherosclerotic group or the non-atherosclerotic group, and we also enrolled an older group with peripheral atherosclerosis disease and an age of at least 45 years. Comparisons were made between the different groups to investigate the cardiovascular and metabolic risk profiles of young type 2 diabetes patients with atherosclerosis. We also used logistic regression models to assess the atherosclerosis risk factors for young patients. Results Compared to older type 2 diabetes patients with atherosclerosis, young patients with atherosclerosis had more deleterious profiles of weight and hyperlipidemia. Only age and diabetes duration were found to be significant independent risk factors for atherosclerosis in young patients. The ratio of the presence of atherosclerosis in the lower extremity arteries alone was significantly higher in young patients than older patients (26.4% vs. 14.0%, P = 0.000). Conclusion Young type 2 diabetes patients with atherosclerosis have more adverse cardiovascular risk profiles and inadequate control of these risk factors. Lower extremity examination is of high importance in young patients. PMID:27391819

    Patients with herpes zoster oticus (HZO) may exhibit diverse symptoms regarding cochleovestibular dysfunction. This study investigated the clinical manifestations of HZO by comparing symptoms associated with dysfunctions of the 7th and 8th cranial nerves (CN VII and VIII, respectively). This study is a retrospective case series. Eighty-one patients with HZO who had dysfunction of CN VII or VIII were included in this study. Electroneuronography (ENoG) values were compared among patient groups with facial weakness. Patients with ipsilateral facial weakness (62 of 81) were more common than those without. Among 81 patients, those with facial weakness, hearing loss, and vertigo were most common, and only 1 patient had vertigo without hearing loss or facial weakness. Most patients with vertigo also had hearing loss (28 of 30), and patients without hearing loss did not have vertigo (19 of 21). While patients with vertigo had worse ENoG values than those without vertigo, ENoG values were not significantly different between patients with and without hearing loss. In conclusion, various clinical manifestations of CN VII and VIII dysfunction are possible in patients with HZO. Patients with vertigo had worse ENoG values than those without, which may indicate that vertigo reflects more severe facial nerve degeneration in HZO patients with facial weakness. PMID:26308524

    Little is known concerning the specific clinical characteristics of patients in persistent vegetative states (PVS). Fifty-one patients from four nursing homes, approximately 3% of the total patients, were identified as being in a PVS. The mean age of the patients was 64.8 +/- 3.2 years (range, 19 to 96 years) and the mean duration of the PVS was 3.3 +/- 5.0 years (range, 1 to 16.8 years), with 13 patients' PVS being longer than 5 years. Cerebrovascular accidents and dementia were the most common causes of the PVS, accounting for 32 of the cases (63%). In the younger patients cerebral trauma secondary to motor vehicle accidents was the most common cause. All 51 patients were fed via tube feeding and 35 patients had urinary catheters (75%). All patients were receiving daily medications, with greater than 50% taking daily vitamins. Over 30% were taking digitalis and/or diuretics and over 32% were taking H2 blockers. Transfer of patients to an acute care hospital was not uncommon, with 31 patients (61%) requiring 63 acute care hospitalizations during their stay in the nursing home. As expected, infections were the most common reason for acute care hospitalization, although 15 of the patients were hospitalized for surgical procedures. Another common problem encountered by the patients was pressure sores, with 78% of patients requiring specific therapy for at least one pressure sore. Surprisingly, only 27 (53%) of 51 patients had a specific resuscitation status designation in the medical chart, and neither presence of a chart designation nor specific resuscitation order was related to the patient's age or the cause or duration of PVS. From these data it would appear that clinical characteristics of patients in PVS are variable. Some patients are young, others are old. The cause varies from cerebrovascular accidents to cerebral trauma. Survival may be prolonged; complications are not uncommon, with some patients requiring acute care hospitalization. PMID:2025140

    Approximately thirty percent of patients with gastric cancer undergo an avoidable lymph node dissection with a higher rate of postoperative complication. Comparing the D1 and D2 dissections, it was found that there is a significant difference in morbidity, favoured D1 dissection without any difference in overall survival. Subgroup analysis of patients with T3 tumor shows a survival difference favoring D2 lymphadenectomy, and there is a better gastric cancer-related death and non-statistically significant improvement of survival for node-positive disease in patients with D2 dissection. However, the extended lymphadenectomy could improve stage-specific survival owing to the stage migration phenomenon. The deployment of centralization and application of national guidelines could improve the surgical outcomes. The Japanese and European guidelines enclose the D2 lymphadenectomy as the gold standard in R0 resection. In the individualized, stage-adapted gastric cancer surgery the Maruyama computer program (MCP) can estimate lymph node involvement preoperatively with high accuracy and in addition the Maruyama Index less than 5 has a better impact on survival, than D-level guided surgery. For these reasons, the preoperative application of MCP is recommended routinely, with an aim to perform "low Maruyama Index surgery". The sentinel lymph node biopsy (SNB) may decrease the number of redundant lymphadenectomy intraoperatively with a high detection rate (93.7%) and an accuracy of 92%. More accurate stage-adapted surgery could be performed using the MCP and SNB in parallel fashion in gastric cancer. PMID:26909128

    The association of low blood pressure (BP) with high mortality is a characteristic for hemodialysis patients. This analysis clarifies the association of BP with mortality and stroke in Japanese hemodialysis (HD) patients and examines the association separately for patients with and without antihypertensive medication (BP meds). We analyzed 9134 patients from Japan in phases 1-4 (1999-2011) of the Dialysis Outcomes and Practice Patterns Study (DOPPS), a prospective cohort study of in-center HD patients. The association of patient systolic (SBP) and diastolic (DBP) blood pressure with all-cause and cause-specific mortality was assessed using adjusted Cox regression. A U-shaped association between BP and all-cause mortality was observed, with lowest mortality for baseline SBP 140-159 mmHg and DBP 65-74 mmHg. Both SBP and DBP were positively and monotonically associated with stroke-related death: hazard ratio (95% confidence interval) was 1.24 (1.01-1.53) per 20 mmHg higher SBP and 1.23 (1.05-1.44) per 10 mmHg higher DBP. No evidence of interaction was found between SBP and use of BP meds regarding all-cause mortality (P for interaction = 0.97); the association between SBP and stroke-related death was slightly stronger among patients not on BP meds than patients on BP meds (P for interaction = 0.09). In Japanese HD patients, both low and high BP are associated with all-cause mortality. This analysis also documents a positive and monotonic association of BP with stroke-related deaths. Although our analysis indicates that the prescription of BP meds to hypertensive patients might protect against stroke-related death, additional study is warranted. PMID:24629041

    Background Although dialysis is typically started in an effort to prolong survival, mortality is reportedly high in the first few months. However, it remains unclear whether this is true in Japanese patients who tend to have a better prognosis than other ethnicities, and if health conditions such as functional status (FS) at initiation of dialysis influence prognosis. Methods We investigated the epidemiology of early death and its association with FS using Japanese national registry data in 2007, which included 35,415 patients on incident dialysis and 7,664 with FS data. The main outcome was early death, defined as death within 3 months after initiation of hemodialysis (HD). The main predictor was FS at initiation of HD. Levels of functional disability were categorized as follows: severe (bedridden), moderate (overt difficulties in exerting basic activities of daily living), or mild/none (none or some functional disabilities). Results Early death remained relatively common, especially among elderly patients (overall: 7.1%; those aged ≥80 years: 15.8%). Severely and even only a moderately impaired FS were significantly associated with early death after starting dialysis (adjusted risk ratios: 3.93 and 2.38, respectively). The incidence of early death in those with impaired FS increased with age (36.5% in those with severely impaired FS and aged ≥80 years). Conclusions Early death after starting dialysis was relatively common, especially among the elderly, even in Japanese patients. Further, early death was significantly associated with impaired FS at initiation of HD. PMID:27270615

    This study aimed to elucidate the clinical efficacy and pharmacokinetics of levothyroxine (LT4) suppository, thus, we examined the pharmacokinetics of thyroxine (T4) after the administration of the suppository in thyroidectomized rats and examined dose and the levels of free T4 (FT4) in patients with hypothyroidism receiving suppositories. Thyroidectomized rats were administered with LT4 solution and LT4 suppository (30 µg/kg), and plasma T4 concentrations were measured using LC/MS. The AUC0-168 of T4 after rectal administration of the LT4 suppository was 64% lower than these values after oral administration. To evaluate clinical effect of LT4 suppository, we enrolled 6 Japanese patients with hypothyroidism (2 men and 4 women; age, 68.2±13.5 years) who were administered LT4 suppository at Kameda Medical Center from 2007 to 2013 in this case series. The FT4 level during the administration of suppositories was significantly lower than that during the administration of tablets (0.657±0.183 ng/dL vs. 1.25±0.51 ng/dL, p=0.034). The FT4/dose ratio for the suppository was significantly 44% lower than that for the tablet (p=0.020). In conclusion, although the bioavailability of LT4 is lower after administration of the suppository than after the oral formulation, it was suggested that T4 levels can be maintained in patients with hypothyroidism by administering LT4 suppositories at a dose 1.8 times higher than that of the tablet. Thus, the administration of LT4 suppository can be an alternative for treatment with oral medication in clinical practice. PMID:24694613

    Objective: To study the clinical profile and outcome of dengue fever in children at a tertiary care hospital in Puducherry. Materials and Methods: All children (0-12 years of age) diagnosed and confirmed as dengue fever from August 2012 to January 2015 were reviewed retrospectively from hospital case records as per the revised World Health Organization guidelines for dengue fever. The diagnosis was confirmed by NS1 antigen-based ELISA test or dengue serology for IgM and IgG antibodies, and the data were analyzed using SPSS 16.0 statistical software. After collecting the data, all the variables were summarized by descriptive statistics. Results: Among the 261 confirmed cases of dengue fever non-severe and severe dengue infection was seen in 60.9% and 39.1%, respectively. The mean age (standard deviation) of the presentation was 6.9 + 3.3 years and male: female ratio was 1.2:1. The most common clinical manifestations were fever (94.6%), conjunctival congestion (89.6%), myalgia (81.9%), coryza (79.7%), headache (75.1%), palmar erythema (62.8%), and retro-orbital pain (51.3%). The common early warning signs at the time of admission were persistent vomiting (75.1%), liver enlargement (59.8%), cold and clammy extremities (45.2%), pain abdomen (31.0%), hypotension (29.5%), restlessness (26.4%), giddiness (23.0%), bleeding (19.9%), and oliguria (18.4%). The common manifestation of severe dengue infection was shock (39.1%), bleeding (19.9%), and multi-organ dysfunction (2.3%). The most common complications were liver dysfunction, acute respiratory distress syndrome, encephalopathy, pleural effusion, ascites, myocarditis, myositis, acute kidney injury, and disseminated intravascular coagulopathy. Platelet count did not always correlate well with the severity of bleeding. There were six deaths (2.3%) and out of them four presented with impaired consciousness (66.6%). The common causes for poor outcome were multiorgan failure, encephalopathy, and fluid refractory shock

    When compared with other epithelial ovarian cancers, the clinical characteristics of ovarian clear cell adenocarcinoma (CCC) include 1) a higher incidence among Japanese, 2) an association with endometriosis, 3) poor prognosis in advanced stages, and 4) a higher incidence of thrombosis as a complication. We used high resolution comparative genomic hybridization (CGH) to identify somatic copy number alterations (SCNAs) associated with each of these clinical characteristics of CCC. The Human Genome CGH 244A Oligo Microarray was used to examine 144 samples obtained from 120 Japanese, 15 Korean, and nine German patients with CCC. The entire 8q chromosome (minimum corrected p-value: q = 0.0001) and chromosome 20q13.2 including the ZNF217 locus (q = 0.0078) were amplified significantly more in Japanese than in Korean or German samples. This copy number amplification of the ZNF217 gene was confirmed by quantitative real-time polymerase chain reaction (Q-PCR). ZNF217 RNA levels were also higher in Japanese tumor samples than in non-Japanese samples (P = 0.027). Moreover, endometriosis was associated with amplification of EGFR gene (q = 0.047), which was again confirmed by Q-PCR and correlated with EGFR RNA expression. However, no SCNAs were significantly associated with prognosis or thrombosis. These results indicated that there may be an association between CCC and ZNF217 amplification among Japanese patients as well as between endometriosis and EGFR gene amplifications. PMID:25658832

    The neuromate is a commercially available, image-guided robotic system for use in stereotactic surgery and is employed in Europe and North America. In June 2015, this device was approved in accordance with the Pharmaceutical Affairs Law in Japan. The neuromate can be specified to a wide range of stereotactic procedures in Japan. The stereotactic X-ray system, developed by a Japanese manufacturer, is normally attached to the operating table that provides lateral and anteroposterior images to verify the positions of the recording electrodes. The neuromate is designed to be used with the patient in the supine position on a flat operating table. In Japan, deep brain stimulation surgery is widely performed with the patient's head positioned upward so as to minimize cerebrospinal fluid leakage. The robot base where the patient's head is fixed has an adaptation for a tilted head position (by 25 degrees) to accommodate the operating table at proper angle to hold the patient's upper body. After these modifications, the accuracy of neuromate localization was examined on a computed tomography phantom preparation, showing that the root mean square error was 0.12 ± 0.10 mm. In our hospital, robotic surgeries, such as those using the Da Vinci system or neuromate, require operative guidelines directed by the Medical Risk Management Office and Biomedical Research and Innovation Office. These guidelines include directions for use, procedural manuals, and training courses. PMID:26511113

    One of the advanced nursing care procedures emphasized by nursing organizations around the world is patient or nursing advocacy. In addition to illustrating the professional power of nursing, it helps to provide effective nursing care. The aim of the present study was to explain the concept of patient advocacy from the perspective of Iranian clinical nurses. This was a qualitative study that examined the viewpoint and experiences of 15 clinical nurses regarding patient advocacy in nursing. The nurses worked in intensive care units (ICUs), coronary care units (CCUs), and emergency units. The study participants were selected via purposeful sampling. The data was collected through semi-structured interviews and analyzed using content analysis. Data analysis showed that patient advocacy consisted of the two themes of empathy with the patient (including understanding, being sympathetic with, and feeling close to the patient) and protecting the patients (including patient care, prioritization of patients’ health, commitment to the completion of the care process, and protection of patients' rights). The results of this study suggest that nurses must be empathetic toward and protective of their patients. The results of the present study can be used in health care delivery, nursing education, and nursing management and planning systems to help nurses accomplish their important role as patient advocates. It is necessary to further study the connections between patient advocacy and empathy. PMID:27471588

    The frequent occurrence of comorbidities in patients with chronic obstructive pulmonary disease (COPD) suggests that they may share pathobiological processes and/or risk factors.To explore these possibilities we compared the clinical diseasome and the molecular diseasome of 5447 COPD patients hospitalised because of an exacerbation of the disease. The clinical diseasome is a network representation of the relationships between diseases, in which diseases are connected if they co-occur more than expected at random; in the molecular diseasome, diseases are linked if they share associated genes or interaction between proteins.The results showed that about half of the disease pairs identified in the clinical diseasome had a biological counterpart in the molecular diseasome, particularly those related to inflammation and vascular tone regulation. Interestingly, the clinical diseasome of these patients appears independent of age, cumulative smoking exposure or severity of airflow limitation.These results support the existence of shared molecular mechanisms among comorbidities in COPD.

    The phospholipase A2 receptor (PLA2R) is the major target antigen (Ag) in idiopathic membranous nephropathy (IMN). Recently, several types of immunoassay systems for anti-PLA2R antibody (Ab) have been developed. However, the correlation of serum anti-PLA2R Abs and glomerular expression of PLA2R Ag, and their association with clinicopathological characteristics have yet to be proven in Japanese patients. We examined serum anti-PLA2R Abs by both ELISA and cell-based indirect immunofluorescence assay (CIIFA), and glomerular PLA2R expression by immunofluorescence (IF) in 59 biopsy-proven MN patients including IMN (n = 38) and secondary MN (SMN) (n = 21). In this study, anti-PLA2R Abs were present in 50% of IMN patients, but was absent in SMN patients. The concordance rate between ELISA and CIIFA was 100%. Serum IgG levels were significantly lower in anti-PLA2R Ab-positive patients. Serum albumin levels correlated inversely with serum anti-PLA2R Ab titers. The prevalence and intensity of glomerular staining for IgG4 by IF were significantly higher in anti-PLA2R Ab-positive patients than in -negative patients. Glomerular PLA2 Ag expression evaluated by IF was positive in 52.6% of IMN patients, but was absent in SMN patients. The concordance rate between the prevalence of glomerular PLA2R Ag expression and anti-PLA2R Ab was 84.2%. The prevalence of anti-PLA2R Abs measured by ELISA/CIIFA was equivalent to previous Japanese studies evaluated using Western blotting. These analyses showed an excellent specificity for the diagnosis of IMN, and anti-PLA2R positivity was associated with some clinicopathological features, especially glomerular IgG4-dominant deposition.

    Castilla-La Mancha Health Service is developing the integration of care levels due to the challenge of an aging population in the region. Aging is associated with chronic diseases and an increasing number of concomitant diseases. This poses a major care challenge care, with more fragile patients and new needs. This also requires a sustainable approach: the concurrence of several chronic diseases affects the cost of care, which is especially acute in times of severe economic crisis. One of the pillars of the strategy for dealing with chronic diseases in our region is care integration, in an effort to adapt the organization to the new needs. The Balanced Scorecard or Integrated Scorecard of the integration process was introduced as it has been designed. The integration of primary and hospital care at an organizational level has already been completed, and the development of integrated care processes has also been performed in order to achieve real integration at care level. To help finance this, a prospective capitation system is gradually being implemented, achieving a convergence of per capita costs in the different health areas integrated. Nurses has a key role in this process, their skills as educators and trainers in self-care, in the role of case managers of patients with particularly complex conditions, and the role of professional liaison to improve the transition between care areas and units.

    Objective Concurrent chemoradiotherapy (CCRT) is the primary treatment for locally advanced cervical cancer. We studied prognostic factors for patients treated with CCRT. Methods We retrospectively reviewed records of 85 consecutive patients with cervical cancer who were treated with CCRT between 2002 and 2011, with external beam radiation therapy, intracavitary brachytherapy, and platinum-based chemotherapy. Survival data were analyzed with Kaplan-Meier methods and Cox proportional hazard models. Results Of the 85 patients, 69 patients (81%) had International Federation of Gynecology and Obstetrics (FIGO) stage III/IV disease; 25 patients (29%) had pelvic lymph node enlargement (based on magnetic resonance imaging), and 64 patients (75%) achieved clinical remission following treatment. Median maximum tumor diameter was 5.5 cm. The 3- and 5-year overall survival rates were 60.3% and 55.5%, respectively. Cox regression analysis showed tumor diameter >6 cm (hazard ratio [HR], 2.3; 95% confidence interval [CI], 1.2 to 4.6), pelvic lymph node enlargement (HR, 2.2; 95% CI, 1.1 to 4.5), and distant metastasis (HR, 10.0; 95% CI, 3.7 to 27.0) were significantly and independently related to poor outcomes. Conclusion New treatment strategies should be considered for locally advanced cervical cancers with tumors >6 cm and radiologically enlarged pelvic lymph nodes. PMID:25310853

    Objective Design, implement, and evaluate a standardized approach to teaching clinical toxicology for pharmacy students. Design An extensive review of the literature was conducted and a standardized approach to teaching Clinical Toxicology, a 1-credit-hour elective course, was designed, consisting of 9 key questions to address any clinical poisoning. A patient-oriented and problem-solving approach to clinical toxicology was adopted throughout the course. Assessment Average performance on course examinations for the academic years 1996-2001 (N=604) when the course was required and the academic years 2002-2007 (N=37) when the course was changed to an elective was 83.4% and 81.7%, respectively. Conclusions A standardized, patient-oriented approach to teaching clinical toxicology allowed successful conversion of this material from a required course to an elective and facilitated students' exposure and interest in this important area of practice.

    Clinical and laboratory data on severe acute respiratory syndrome (SARS), particularly on the temporal progression of abnormal laboratory findings, are limited. We conducted a prospective study on the clinical, radiologic, and hematologic findings of SARS patients with pneumonia, who were admitted to National Taiwan University Hospital from March 8 to June 15, 2003. Fever was the most frequent initial symptom, followed by cough, myalgia, dyspnea, and diarrhea. Twenty-four patients had various underlying diseases. Most patients had elevated C-reactive protein (CRP) levels and lymphopenia. Other common abnormal laboratory findings included leukopenia, thrombocytopenia, and elevated levels of aminotransferase, lactate dehydrogenase, and creatine kinase. These clinical and laboratory findings were exacerbated in most patients during the second week of disease. The overall case-fatality rate was 19.7%. By multivariate analysis, underlying disease and initial CRP level were predictive of death. PMID:15200814

    This paper proposes a Web clinical decision support system for clinical oncologists and for breast cancer patients making prognostic assessments, using the particular characteristics of the individual patient. This system comprises three different prognostic modelling methodologies: the clinically widely used Nottingham prognostic index (NPI); the Cox regression modelling and a partial logistic artificial neural network with automatic relevance determination (PLANN-ARD). All three models yield a different prognostic index that can be analysed together in order to obtain a more accurate prognostic assessment of the patient. Missing data is incorporated in the mentioned models, a common issue in medical data that was overcome using multiple imputation techniques. Risk group assignments are also provided through a methodology based on regression trees, where Boolean rules can be obtained expressed with patient characteristics.

    Patient-reported outcome (PRO) questionnaires assess topics a patient can report about his or her own health. This includes symptoms (eg, nausea, fatigue, diarrhea, pain, or frequent urination), physical functioning (eg, difficulty climbing stairs or difficulty fastening buttons), and mental health (eg, anxiety, fear, or worry). Electronic PRO (ePRO) systems are used in oncology clinical care because of 1) their ability to enhance clinical care by flagging important symptoms and saving clinicians time; 2) the availability of standardized methods for creating and implementing PROs in clinics; and 3) the existence of user-friendly platforms for patient self-reporting like tablet computers and automated telephone surveys. Many ePRO systems can provide actionable links to clinical care such as summary reports in a patient's electronic medical record and real-time e-mail alerts to providers when patients report acute needs. This review presents 5 examples of ePRO systems currently in use in oncology practice. These systems support multiple clinical activities, including assessment of symptoms and toxicities related to chemotherapy and radiation, postoperative surveillance, and symptom management during palliative care and hospice. Patient self-reporting is possible both at clinical visits and between visits over the Internet or by telephone. The implementation of an ePRO system requires significant resources and expertise, as well as user training. ePRO systems enable regular monitoring of patient symptoms, function, and needs, and can enhance the efficiency and quality of care as well as communication with patients.

    2014-01-01

    Background and aims: Pigmented lesions, e.g., senile lentigo and seborrheic keratosis are commonly seen in photodamaged skin in the Japanese general population. The use of the laser to treat such lesions is often painful, and intense pulsed light (IPL) systems have become widely used. Clearly demarcated pigmented lesions may be identified easily and treated with IPL. Less well demarcated lesions, however, which are very difficult to identify or thick melanogesic lesions like seborrheic keratosis represent one of the most challenging conditions to be treated using IPL. This pilot study evaluated carbon suspension-assisted IPL treatment of such lesions. Subjects and methods: Three female Japanese patients, Fitzpatrick skin type III–IV, comprised the subjects, aged 58, 78 and 85, with indistinct senile lentigines or thick seborrheic keratoses. The lesions were painted or demarcated with a carbon-based ink from a commercially-available Japanese writing instrument (Fude-pen™, Pentel, Japan) consisting of a brush-like pen nib with a refillable or replaceable ink reservoir, and then treated with a broadband (560 – 1200 nm) IPL system. Results: The poorly-demarcated lesions were quickly and easily marked with the pen, and the IPL treatments were well-tolerated. All patients had good improvement in their painted pigmented lesions based on the overall evaluation, compared with unpainted ones. Side effects after treatment, such as hyperpigmentation, persistent erythema, and scarring, were minimal. Conclusions: Topical carbon suspension-assisted IPL treatment could be a good option for patients with indistinct pigmented or thick melanogenesic lesions. Adverse reactions to this treatment were minimal and the results acceptable, though appropriate lesions need to be chosen carefully. PMID:24771967

    Two Japanese siblings visited the Cook Islands on business and stayed for 2 months. The sister developed a high fever, arthralgia, erythema and leg edema on the day after returning to Japan. The brother also developed neck and joint pain on the day following the sister's onset. Subsequently, his erythematous lesions spread over his whole body. Chikungunya virus was detected from the sister's blood and urine by specific reverse transcription polymerase chain reaction, but not in the brother's samples. Retrospectively, his history of Chikungunya fever was confirmed by the presence of the anti-Chikungunya virus immunoglobulin (Ig)M and IgG antibodies using the specific enzyme-linked immunoassay. In Japan, no autochthonous case of Chikungunya fever was reported previously. We should give attention to the imported infectious diseases for epidemic prevention. This report warns about the danger of the imported infectious diseases, and also suggests that covering the topic of infectious disease in the world is critical to doctors as well as travelers.

    To investigate the prevalence of hepatitis B virus (HBV) genotypes and characteristics of HBV isolates among Japanese patients infected with human immunodeficiency virus type 1 (HIV), serum samples collected between September 1990 and March 2002 from 471 HIV-infected patients (age, 38.8 +/- 11.4 [mean +/- standard deviation] years; male, 90%) were tested for hepatitis B surface antigen (HBsAg) and HBV DNA. Positivity for HBsAg and HBV DNA was seen in 42 patients (8.9%), 41 of whom had contracted HIV infection through sexual activity and 1 had hemophilia. Genotypes of HBV were determined by comparative and phylogenetic analyses of the S gene sequence (396 nucleotides [nt]). The distribution of HBV genotypes among the 42 HBV-viremic patients was: A (50%), B (5%), C (24%), D (5%), E (2%), H (10%), A plus D (2%), A plus G (2%). The hemophilia patient had HBV genotype D. Genotypes E, G, and H which had not been reported in Japan, were found in one patient each who had traveled to Zambia, the US, and South America, respectively. Genotypes A and D, which are rare in Japan, were found in patients who had no history of traveling abroad. The entire genome of the HB-JI411 (genotype E [3,212 nt]), HB-JI444G (genotype G [3,248 nt]), and HB-JI260 (genotype H [3,218 nt]) isolates had the highest identity of 98.3%, 99.9%, and 98.5%, respectively, with reported HBV isolates of the same genotype. Most Japanese patients coinfected with HIV and HBV had HBV genotypes that are found rarely or had not been reported in Japan. PMID:15779062

    The Patient-Centered Outcomes Research Institute (PCORI) has launched PCORnet, a major initiative to support an effective, sustainable national research infrastructure that will advance the use of electronic health data in comparative effectiveness research (CER) and other types of research. In December 2013, PCORI's board of governors funded 11 clinical data research networks (CDRNs) and 18 patient-powered research networks (PPRNs) for a period of 18 months. CDRNs are based on the electronic health records and other electronic sources of very large populations receiving healthcare within integrated or networked delivery systems. PPRNs are built primarily by communities of motivated patients, forming partnerships with researchers. These patients intend to participate in clinical research, by generating questions, sharing data, volunteering for interventional trials, and interpreting and disseminating results. Rapidly building a new national resource to facilitate a large-scale, patient-centered CER is associated with a number of technical, regulatory, and organizational challenges, which are described here.

    Pregnancy with paroxysmal nocturnal hemoglobinuria (PNH) is associated with significant risk of complications, such as life-threatening thrombosis. Recently, eculizumab has come into clinical use and revolutionized the treatment of PNH. However, clinical information regarding eculizumab use for PNH during pregnancy is limited. The present report describes pregnancies with PNH treated with eculizumab that were registered with the Japan PNH study group and reviews the literature. In case 1, the patient received eculizumab throughout pregnancy and delivered a healthy neonate at term, although breakthrough hemolysis occurred at 20 weeks of gestation. In case 2, the patient discontinued eculizumab before pregnancy and developed preeclampsia at 27 weeks of gestation. She received eculizumab and delivered a preterm, but healthy, neonate by cesarean section. In case 3, the patient received eculizumab from 18 weeks of gestation and delivered a healthy neonate at term without any complications. Reports of 11 pregnant women treated with eculizumab were identified in the literature. Of 14 pregnancies, including our own cases, breakthrough hemolysis and preeclampsia occurred in five and two cases, respectively. There were no thrombotic complications, maternal or neonatal deaths, or fetal structural abnormalities. Thus, eculizumab appears to be safe and effective for managing PNH during pregnancy.

    The aim of the present study was to clarify the association between child abuse experiences and drug addiction severity among Japanese drug-dependent patients using the Addiction Severity Index-Japanese version (ASI-J). One hundred and eleven inpatients and outpatients with drug dependence participated in the study. Some of the questions on the ASI-J asked about lifetime experiences of abuse. A higher percentage of female participants experienced child abuse compared with male participants. Male participants who experienced child abuse (MEA) had a significantly higher severity of drug use than men who did not experience it (MNEA). Female participants who experienced child abuse (FEA) had significantly more serious problems in family/social relationships than female participants who did not experience it (FNEA). Patients in the MEA group were arrested less frequently for drug charges, experienced more serious problems with their fathers, and experienced more severe anxiety in their lifetime compared with the MNEA group. The FEA group experienced more serious troubles with their sexual partners, close friends, and families and experienced more severe psychiatric problems in their lifetime compared with the FNEA group. These results suggest gender differences in the problems experienced by drug-dependent patients with child abuse experiences, and gender-specific interventions may be more effective in treating their drug dependence.

    Subcutaneous sarcoidosis is the specific subset of cutaneous sarcoidosis frequently associated with systemic disease. However, the disease activity, severity, and prognosis have not yet been elucidated due to the limited number of reported cases. The purpose of this study was to identify the clinical, laboratory, and prognostic differences between subcutaneous sarcoidosis and other type of cutaneous sarcoidosis. All patients with sarcoidosis diagnosed histopathologically from 2000 to 2012 at our institution were enrolled. The clinical, laboratory, chest X-ray, and pulmonary function test results were retrospectively evaluated in the patients with cutaneous sarcoidosis. In the 130 patients with sarcoidosis, cutaneous sarcoidosis was diagnosed in 37 patients (28.4 %), and 9 (6.9 %) of these patients had subcutaneous sarcoidosis. The serum levels of soluble interleukin-2 receptor (sIL-2R) were significantly elevated in the group of patients with subcutaneous sarcoidosis in comparison to the patients with other types of cutaneous sarcoidosis, whereas there was no significant difference in the severity score between the two groups. Following a 2-year observation period, three patients were in remission, five patients demonstrated stable disease, and one patient had progressive disease. Subcutaneous sarcoidosis may be associated with the disease activity, although it was not found to be associated with the disease severity and it was not a predictive factor for the prognosis. Furthermore, the prevalence of subcutaneous sarcoidosis may be higher than that in previously reported series. PMID:27449952

    Background Many patients present to dental clinics for treatment of painful conditions. Prior to seeking treatment, many of these patients will self-medicate with non-prescription analgesics (NPA), and some will unintentionally overdose on these products. The objective of this study is to describe the use of NPA among dental patients. Methods All adult patients presenting to an urban dental clinic during a two-week period in January and February of 2001 were approached to participate in this research project. Trained research assistants using a standardized questionnaire interviewed patients. Patient demographics and the NPA usage over the 3 days preceding the office visit were recorded. We defined a supra-therapeutic dose as any dose greater than the total recommended daily dose stated on package labeling. Results We approached 194 patients and 127 participated. The mean age of participants was 35.5 years, 52% were male. Analgesic use preceding the visit was reported by 99 of 127 patients, and most (81/99) used a NPA exclusively. Fifty-four percent of NPA users were taking more than one NPA. NPA users reported using ibuprofen (37%), acetaminophen (27%), acetaminophen/aspirin combination product (8%), naproxen (8%), and aspirin (4%). Sixteen patients reported supra-therapeutic use of one or more NPA (some ingested multiple products): ibuprofen (14), acetaminophen (3), and naproxen (5). Conclusion NPA use was common in patients presenting to a dental clinic. A significant minority of patients reported excessive dosing of NPA. Ibuprofen was the most frequently misused product, followed by naproxen and acetaminophen. Though mostly aware of the potential toxicity of NPA, many patients used supra-therapeutic dosages.

    Erythema nodosum (EN) represents an acute, erythematous nodular eruption that is generally found on the lower aspects of the legs. Despite the variety of triggering factors, the clinical findings of EN are classic. It is often hard to determine which patients have an underlying systemic disorder. The aim of this study was to investigate clinical and laboratory parameters in patients with EN, especially those with an underlying systemic disorder. A total of 43 patients diagnosed with EN at an adult and children's hospital were retrospectively reviewed for triggering factors, any underlying systemic diseases, clinical features, laboratory parameters, treatment modalities, and disease outcome. The mean age of the patients was 40.91±15.57 years (minimum 7 years, maximum 71 years). Patients with an underlying systemic disorder were grouped as complicated EN (CEN), patients without an underlying disorder were grouped as non-complicated EN (NCEN). Patients with EN more frequently presented with more nonpretibial localizations than patients with NCEN (P=.023). Platelet levels in patients with CEN were significantly higher than in patients with NCEN (P=.036). Erythrocyte sedimentation rate, C-reactive protein, and procalcitonin levels did not differ among the two groups (P>.05). Hospitalization shortened the active disease duration (P=.046). EN lesions present on the nonpretibial area, which may be a clue for systemic associations of the disease. The presence of elevated platelet levels may indicate systemic inflammatory and infectious diseases in patients with EN. Procalcitonin, which is a marker for systemic infection, was not helpful in detecting chronic infections such as tuberculosis or systemic fungal infections in patients. PMID:27319952

    It is not yet clear whether a difference in in-hospital morality between patients with and without renal insufficiency undergoing percutaneous coronary intervention (PCI) exists. Therefore, the aim of the present study was to investigate if such as association exists in Japan. Data from the Tokai Acute Myocardial Infarction Study II were used. This was a prospective study of all 3274 patients admitted with acute myocardial infarction (AMI) to the 15 participating hospitals from 2001 to 2003. We abstracted the baseline and procedural characteristics as well as in-hospital mortality from detailed chart reviews. Patients were stratified into 2 groups according to the estimated creatinine clearance on admission. The creatinine clearance values were available in 2116, 107 of whom had renal insufficiency. The patients with renal insufficiency were more likely to be older, female, not independent in their daily activities, have lower body mass index and higher heart rate values on admission, lower prevalences of hypercholesterolemia and peptic ulcers, greater prevalences of diabetes, angina, previous heart failure, previous renal failure, previous cerebrovascular disease, aortic aneurysm, worse clinical course such as bleeding, and a multivessel coronary disease. Vasopressors, an intra-aortic balloon pump, and mechanical ventilation were frequently used in the patients with renal insufficiency, while thrombolytics were used less frequently. The patients with renal insufficiency had a higher in-hospital mortality rate than those without. Multivariate analysis identified renal insufficiency as an independent predictor of in-hospital death. The results suggest that renal insufficiency is an independent predictor of in-hospital death among AMI patients undergoing PCI. PMID:17106145

The primary diseases included chronic intestinal pseudoobstruction (CIPO: n = 4), short bowel syndrome (SBS: n = 2), and intestinal atresia (n = 1). All patients orally received NJT extract granules at a dose of 0.3 g/kg BW per day. The treatment outcomes were then assessed according to the patients' symptoms and consecutive abdominal X-ray findings. Results. The targeted symptoms were abdominal distension in four patients, diarrhea in three patients, and frequent hospitalization due to infections in two patients. An improvement in the symptoms was observed in six of the seven patients, whereas one patient with SBS did not show any improvement. An improvement in an abdominal roentgenogram was observed in the four patients with remarkably dilated bowel loops due to CIPO. Conclusions. NJT may be effective in controlling functional gastrointestinal disorders associated with chronic intestinal failure. The use of Kampo medicine in the field of pediatric surgery may help to improve the quality of life in children suffering from such conditions. PMID:26495014

    Background To evaluate the efficacy and safety of newly formulated brimonidine (0.1% brimonidine tartrate preserved with sodium chlorite: brimonidine) as add-on therapy in on-treatment Japanese normal-tension glaucoma (NTG) patients. Methods Brimonidine was added to on-treatment NTG patients with intraocular pressures (IOP) of between 13 mmHg and 16 mmHg after three consecutive IOP measurements. The time courses of IOP, conjunctival hyperemia, superficial punctate keratitis, and adverse events were examined at 4, 8, and 12 weeks after brimonidine instillation. Results Though 75 of 83 patients (31 males and 52 females; mean age: 63.4±11.6 years) completed the study, six patients discontinued because of side effects and two patients withdrew. The mean IOP after brimonidine addition at week 4 (12.6±1.8 mmHg, P<0.001), week 8 (12.4±1.7 mmHg, P<0.001), and week 12 (12.6±1.8 mmHg, P<0.001) was significantly decreased compared with that before the addition of brimonidine (13.9±1.2 mmHg). No significant changes in superficial punctate keratitis or conjunctival hyperemia scores were observed throughout the study. Dizziness, sleepiness, eye pain, and itching (mild to moderate) were noted in five, four, three, and three patients, respectively. Conclusions The addition of newly formulated brimonidine to on-treatment Japanese NTG patients with IOP of 13–16 mmHg further reduced the levels of IOP with minimal side effects and adverse events.

    Patient and family engagement is a strategy to enhance healthcare outcomes through strong clinician-patient partnerships. A new care delivery process, in which the patient is the driver of the healthcare team, is required to achieve optimal health. A summit partially funded by a seed grant from the Robert Wood Johnson Executive Nurse Fellow Alumni Foundation was held with interprofessional colleagues and patient representatives to identify needed clinical competencies and future practice changes. Recommended shifts in the care delivery process included a focus on patient strengths, including the patient as a valued team member, doing care "with me" and not "to me," and considering all entities or providers including the patient, as equal partners.

    Patient participation, which has been established since 2004, has brought more attention to patients' concerns in healthcare. More and more endpoints in clinical trials are defined with respect to their relevance for patients. But this development has still been found wanting. For important drugs, no evidence-based benefit has been demonstrated in the benefit assessment, which also has become possible since 2004. Furthermore, this assessment has arrived too late for patients who have been medicated for a long time. Healthcare policies, applicants and stakeholders have contributed a lot to the patients' scepticism towards benefit assessments, though, in principle, patients are interested in high evidence levels and reasonable pricing. New drugs are often licensed under less ambitious conditions. Whether this is in the patients' interest needs to be put up for a large-scale, and societal, discussion. PMID:20608257

    Cardiovascular surgery in Jehovah's Witness is challenging for surgeons on the ground that they refuse blood transfusion. We report 11 cases of cardiovascular surgery. All of the patients underwent elective surgery with cardiopulmonary bypass. Two cases underwent minimally invasive procedures. The mean preoperative hemoglobin level was 13.0 g/dl, and hematopoietic medicines were preoperatively administrated in 4 patients. Although 10 patients recovered satisfactory without blood transfusion, 1 surgical case was lost due to uncontrollable postoperative bleeding. The clinical outcomes of the Jehovah's Witness patients are considered to be satisfactory. However, careful indication is recommended in high risk cases. PMID:27075280

    This article defines shared decision making in patient care and describes the background to this philosophy. The shared decision making approach is part of a wider initiative to promote patient-centred care and increase patient involvement in clinical decisions. Shared decision making recognises patients' rights to make decisions about their care and is used to assist them to make informed and individualised decisions about care and treatment. As well as reviewing the principles of shared decision making, the article offers practical guidance on how nurses can implement this initiative, including information on sharing expertise, agenda setting, assessing risks and benefits, setting goals, and support and follow up.

    We cared for 124 pediatric patients with a histologic diagnosis of Langerhans' cell histiocytosis (histiocytosis X) over a period of 14 years. Clinical, laboratory, and radiographic findings were analyzed. The most frequent manifestations were bone lesions, lymph node involvement, and skin infiltration. Liver disease was noted in 50% of patients and lung disease in 23%; hematologic changes were also frequent. Dysfunction and involvement of these three organ systems, plus age of onset, distinguished the group of patients with the highest mortality. All patients with generalized disease or organ dysfunction were treated with systemic chemotherapy. The actuarial survival curve at 10 years was 63%. PMID:3264610

    Social workers are in an excellent position to develop clinical interventions to enhance patient control over decision making about post hospital care. Participation in decision making has been identified in many studies as influencing well-being, health status and even mortality rates for elderly individuals facing relocation. Some of the practice patterns that support patient autonomy include: (1) involving the patient when working with families; (2) reaching for underlying conflict; (3) creating a sense of choice within existing parameters; (4) preparing patients for discharge; and (5) educating families and hospital caretakers to assist in this process.

    Fabry disease is an X-linked recessive inborn error of glycosphingolipid catabolism caused by a mutation in the GLA gene. We sequenced the α-galactosidase A gene (GLA) of a patient who had been clinically diagnosed with late-onset Fabry disease. Abundant globotriaosylceramide was present in his urine, which indicated typical Fabry disease. Here, we report a novel hemizygous mutation, c.207C>A (Phe69 Leu), which caused a mild/late-onset form of Fabry disease. PMID:27081550

    Study Design Prospective cohort study. Purpose To identify differences in time-dependent perioperative changes between the Japanese Orthopaedic Association (JOA) score and the JOA Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) score in patients with cervical spondylotic myelopathy (CSM) and posterior longitudinal ligament (OPLL) who underwent cervical laminoplasty. Overview of Literature The JOA score does not take into consideration patient satisfaction or quality of life. Accordingly, the JOACMEQ was designed in 2007 as a patient-centered assessment tool. Methods We studied 21 patients who underwent cervical laminoplasty. We objectively evaluated the time-dependent changes in JOACMEQ scores and JOA scores for all patients before surgery and at 2 weeks, 3 months, 6 months, and 1 year after surgery. Results The average total JOA score and the recovery rate improved significantly after surgery in both groups, with a slightly better recovery rate in the OPLL group. Cervical spine function improved significantly in the CSM group but not in the OPLL group. Upper- and lower-extremity functions were more stable in the CSM group than in the OPLL group. The effectiveness rate of the JOACMEQ for measuring quality of life was quite low in both groups. In both groups, the Spearman contingency coefficients were dispersed widely except for upper- and lower-extremity function. Conclusions Scores for upper- and lower-extremity function on the JOACMEQ correlated well with JOA scores. Because the JOACMEQ can also assess cervical spine function and quality of life, factors that cannot be assessed by the JOA score alone, the JOACMEQ is a more comprehensive evaluation tool.

    With the recent Center for Medicare and Medicaid Services and stimulus package incentives for health information technology, many clinicians are expected to adopt or enhance their use of e-prescribing systems. E-prescribing has nearly eradicated medication errors resulting from prescriber handwriting interpretations, yet several other patient-care and workflow benefits still remain a promise. As prescribers select or update their e-prescribing systems (whether stand-alone or integrated with electronic health records), close attention is needed to the e-prescribing application features and level of clinical decision support to avoid clinical blind spots, including incomplete or inaccurate patient medication lists, poor drop-down menu or screen design, and lack of clinically relevant and actionable drug interaction and drug allergy alerts. This article presents three case studies that highlight common e-prescribing problems involving diabetes patients. PMID:20144439

    Central pontine myelinolysis (CPM), a potentially fatal and debilitating neurological condition, was first described in 1959 in a study on alcoholic and malnourished patients. It is a condition most frequently related to rapid correction of hyponatremia. Chronic alcoholism associated CPM tends to be benign with a favorable prognosis compared to CPM secondary to rapid correction of hyponatremia. We describe a normonatremic, alcoholic patient who presented with CPM after a rapid rise in his sodium levels. Our case illustrates the fact that CPM can manifest even in patients who are normonatremic at baseline. Rapid rises in sodium levels should be promptly reversed before clinical symptoms manifest in patient with risk factors for CPM irrespective of their baseline sodium levels. Furthermore, clinical evolution of CPM can be difficult to discern from the natural course of alcohol withdrawal delirium, requiring astuteness and maintenance of a high degree of clinical suspicion on the part of the physician.

    2013-01-01

    Background Non-steroidal anti-inflammatory drugs (NSAIDs) are an effective and common treatment for chronic pain disorders, but long-term use is associated with risk of potentially life-threatening gastrointestinal adverse events (AEs). The proton pump inhibitor esomeprazole has been found to be effective for gastroprotection in NSAID users, but few long-term studies have been conducted in Japan. Methods This was an open-label, multicentre, single-arm, prospective 1-year study of treatment with esomeprazole (20 mg once daily) in Japanese patients (aged ≥20 years) with endoscopic evidence of previous peptic ulcer and receiving daily oral NSAID therapy (at a stable dose) for a chronic condition. Eligibility was not dictated by type of oral NSAID. The primary objective was to determine long-term safety and tolerability of esomeprazole. Efficacy for prevention of peptic ulcers was also determined (Kaplan-Meier method). All statistical analyses were descriptive. Results A total of 130 patients (73.1% women, mean age 62.1 years, 43.8% Helicobacter pylori-positive) received treatment with esomeprazole in addition to long-term NSAID therapy (most commonly for rheumatoid arthritis [n=42] and osteoarthritis [n=34]). Loxoprofen, meloxicam and diclofenac were the most commonly used NSAIDs; cyclo-oxygenase (COX)-2 selective agents were used by 16.2% of patients (n=21). Long-term compliance with esomeprazole (capsule counts) was >75% for the majority of patients. Although 16.9% of patients (n=22) experienced AEs judged to be possibly related to treatment with esomeprazole, they were mostly mild and transient. The most commonly reported possibly treatment-related AEs were abnormal hepatic function, headache, increased γ-glutamyltransferase levels and muscle spasms (2 patients each). Overall, 95.9% (95% confidence interval: 92.3, 99.4) of patients remained ulcer free at 1 year. Conclusion Long-term treatment with esomeprazole (20 mg once daily) is well tolerated and

    Scope: To discuss the rationale behind informed consent in clinical trials focusing on vulnerable patients from a European and German viewpoint. Methods: Scientific literature search via PubMed, Medline, Google. Results: Voluntary informed consent is the cornerstone of policies regulating clinical trials. To enroll a patient into a clinical trial without having obtained written and signed consent is to be considered as a serious issue in the conduct of a clinical trial. Development of ethical guidance for physicians started before Christ Era with the Hippocratic Oath. Main function of consent, as articulated in all guidelines developed for clinical research, is to facilitate an individual’s freedom of choice, respect autonomy, and thus to ensure welfare of the participants in clinical trials. Minors are unable to provide legally binding informed consent, this issue is addressed through a combination of parental permission and minor’s assent. Illiteracy is a critical problem that affects all corners of our earth; it has no boundaries and exists among every race and ethnicity, age group, and economic class. New strategies to improve communication with patients including the use of videotapes or animated cartoon illustrations could be taught. Finally the time with the potential participant seems to be the best way to improve understanding. Conclusion: Discovery of life saving and life enhancing new treatments requires partnership that is based on good communication and trust between patients and researchers, sponsors, ethics committees, authorities, lawyers and politicians so that vulnerable patients can benefit from the results of well controlled clinical trials.

    Purpose To identify inexpensive, noninvasive, portable, clinical assessment tools that can be used to assess functional performance measures that may put older patients at risk for falls such as balance, handgrip strength, and lumbopelvic control. Patients and methods Twenty fragility fracture patients and 21 healthy control subjects were evaluated using clinical assessment tools (Nintendo Wii Balance Board [WBB], a handheld dynamometer, and an application for the Apple iPod Touch, the Level Belt) that measure functional performance during activity of daily living tasks. The main outcome measurements were balance (WBB), handgrip strength (handheld dynamometer), and lumbopelvic control (iPod Touch Level Belt), which were compared between fragility fracture patients and healthy controls. Results Fragility fracture patients had lower scores on the vertical component of the WBB Torso Twist task (P=0.042) and greater medial–lateral lumbopelvic sway during a 40 m walk (P=0.026) when compared to healthy controls. Unexpectedly, the fracture patients had significantly higher scores on the left leg (P=0.020) and total components (P=0.010) of the WBB Single Leg Stand task as well as less faults during the left Single Leg Stand task (P=0.003). Conclusion The clinical assessment tools utilized in this study are relatively inexpensive and portable tools of performance measures capable of detecting differences in postural sway between fragility fracture patients and controls.

However, clinics marketing 'adipose-derived mesenchymal stem cell treatments' are proliferating across the USA. These businesses typically claim to operate in compliance with federal regulations, but careful review of their commercial practices suggests that such clinics are marketing unapproved and noncompliant biological drugs.

In order to achieve these aims, the relative emphases on the ethical principles underlying research need to be changed. The current model based on the principle of beneficence must be left behind, and one that upholds the ethical principles of autonomy and non maleficence should be embraced. There is a need to improve the level of information that patients and society as a whole have on research objectives and processes; the goal is to promote the gradual emergence of the expert patient.

    Clinical trials of late-stage breast cancer patients and late-stage melanoma patients treated by laser immunotherapy (LIT) have shown promising results. In a 2010 study of Li et al, eleven late-stage melanoma patients received LIT in one or multiple 6-week treatment cycles applied to a 200-cm2 treatment site, which usually contained multiple cutaneous metastases. Long-term, positive response was observed in six patients. All lesions in the treatment area of the patients responded to LIT, eight of which achieved complete local response (CLR). CLR was observed in the non-treatment site (regional) lesions in four patients. Five patients were still alive at the time of last follow-up. The probability of 12-month overall survival was 70%.2 In 2011, Li et al, treated ten late stage breast cancer patients with LIT.1 In 8 patients available for evaluation, the objective response rate was 62.5% and the clinical beneficial response rate was 75%.1 This review demonstrates that LIT is safe and well tolerated, so it can be easily applied on an outpatient basis and can be combined with other pharmaceutical modalities to improve the therapeutic response of metastatic cancers.

    Atopic dermatitis is a common skin disorder with an age onset mainly from infancy to adolescence. Patients with this disorder usually have a long history of repeated relief and relapse. The aim of the present studies is to quantify the relationship between the QOL score of patients and symptomatic characteristics (including severity measured by SF-36). From November 2000 to February 2001, the study recruited 281 patients with atopic dermatitis who had been treated at the Nagano dermatology and allergology clinic. The results of this study demonstrated that the symptoms severity and pruritus grade had strong influences on QOL score, and the location of pruritic lesion on the neck had the strongest influence on their self-perceived health status. The patients group with moderate atopic dermatitis who showed pruritus lesion in face, neck, and or knee, and female had consistently lower scores than male on all of the subscales. In conclusion, it is critically important to control of pruritus, and to develop an appropriate management. PMID:12522320

    In order to know the epidemiological and clinical features of trichinosis, the data of 208 patients with trichinosis from 1992 to 1994 were analysed. The results showed that these patients came from 11 districts, and acquired the infection mainly by tasting the raw pork filling for dumplings or ingesting instant-boiled pork or mutton. The incidence of trichinosis is high in winter. Young and middle-aged workers and cadres constituted the majority of the patients and the infection was more common in the males than in females. The main clinical manifestations of trichinosis were prolonged fever, general myalgia, muscle weekness and eosinophilia. Most of the patients had no gastrointestinal symptoms and skin eruption. Eyelid edema was only seen in the early stage. Serological tests were significant value in the diagnosis of trichinosis. The key measures to prevent trichinosis were that meat inspection should be strictly carried out and bad eating habit changed. PMID:9387626

    BACKGROUND Multiple lines of evidence indicate a strong genetic contribution to autism spectrum disorders (ASDs). Current guidelines for clinical genetic testing recommend a G-banded karyotype to detect chromosomal abnormalities and fragile X DNA testing, but guidelines for chromosomal microarray analysis have not been established. PATIENTS AND METHODS A cohort of 933 patients received clinical genetic testing for a diagnosis of ASD between January 2006 and December 2008. Clinical genetic testing included G-banded karyotype, fragile X testing, and chromosomal microarray (CMA) to test for submicroscopic genomic deletions and duplications. Diagnostic yield of clinically significant genetic changes was compared. RESULTS Karyotype yielded abnormal results in 19 of 852 patients (2.23% [95% confidence interval (CI): 1.73%–2.73%]), fragile X testing was abnormal in 4 of 861 (0.46% [95% CI: 0.36%–0.56%]), and CMA identified deletions or duplications in 154 of 848 patients (18.2% [95% CI: 14.76%–21.64%]). CMA results for 59 of 848 patients (7.0% [95% CI: 5.5%–8.5%]) were considered abnormal, which includes variants associated with known genomic disorders or variants of possible significance. CMA results were normal in 10 of 852 patients (1.2%) with abnormal karyotype due to balanced rearrangements or unidentified marker chromosome. CMA with whole-genome coverage and CMA with targeted genomic regions detected clinically relevant copy-number changesin7.3%(51 of 697) and 5.3%(8 of 151) of patients, respectively, both higher than karyotype. With the exception of recurrent deletion and duplication of chromosome 16p11.2 and 15q13.2q13.3, most copy-number changes were unique or identified in only a small subset of patients. CONCLUSIONS CMA had the highest detection rate among clinically available genetic tests for patients with ASD. Interpretation of microarray data is complicated by the presence of both novel and recurrent copy-number variants of unknown significance

    We sequenced approximately 23 kb genomic regions containing all the coding exons and their franking introns of two breast cancer susceptibility genes, BRCA1 and BRCA2, of 55 individuals from 50 unrelated Japanese breast cancer families. We identified 55 single-nucleotide polymorphisms (SNPs) (21 in BRCA1 and 34 in BRCA2) containing nine pathogenic protein-truncating mutations (four in BRCA1 and five in BRCA2 from ten patients). Among the remaining 46 SNPs, allele frequencies of 40 were examined in both the breast cancer patients and 28 healthy volunteers with no breast cancer family history by PCR-RFLP or by direct DNA sequencing. Twenty-eight SNPs were common and were also found in the healthy volunteers and/or a SNP database. The remaining 18 were rare (allele frequency <0.05) and were not found in the healthy volunteers and/or the database. The pathogenic significance of these coding SNPs (cSNPs) remains to be clarified. The SNP information from this study will be useful in the future genetic testing of both BRCA1 and BRCA2 genes in the Japanese population. PMID:15168169

We performed retrospective study which included 84 patients with pineal region expansions in the period from 1992 to 2009. The study included 55 women and 29 men, mean age 30.08 +/- 13.93 years, with positive brain magnetic resonance imaging (MRI)--70 patients (83.4%) had simple pineal gland cysts, and 14 patients (16.67%) had expansive process in pineal region with compressive effect. All patients had headache, while 32 patients (38%) had epileptic phenomena--primary generalized seizures. Patients had common electroencephalography (EEG) pattern with paroxysmal discharges of 3Hz (or more than 3 Hz) spike-and-wave complexes. Operation with supracerebellar infratentorial approach was performed in 70 patients. In most of our patients indication for the operation was established based on the size of the cyst (15 mm or more), with the signs of compression on the quadrigeminal plate and compression of the surrounding veins, which could result in seizures and EEG changes verified in our group of patients. Pathohistological analysis revealed pineocytomas in 11 cases (15.71%), pinealoblastomas in 2 cases (2.86%), one case of teratoma (1.43%), while 56 patients had pineal gland cysts (80%). Following surgery clinical condition improved in all patients--patients became seizure-free and headaches significantly decreased. Other symptoms including diplopiae, nausea, vomiting, vertigo as well as blurred vision also disappeared. There were no complications after surgical procedures. This study points to often appearance of seizures that clinically and neurophysiologically present as primary generalized epilepsy in patients with pineal region expansions. Our hypotheses are that mass effect on the surrounding veins that affects normal perfusion, compressive effect on the quadrigeminal plate and the

    Atopic dermatitis (AD) is a common skin disease encountered in both humans and dogs. Canine AD can be used in the analysis of naturally occurring AD; however, details of clinical comparison have been lacking. The purpose of this study is to compare those clinical features using the human diagnostic criteria (Japanese Dermatological Association, 2009). Fifty-one dogs with canine AD were evaluated by the human criteria. Prior to this study, canine AD was basically diagnosed by the fulfillment of two authentic canine AD criteria and a positive reaction against Dermatophagoides farinae in serum immunoglobulin E levels and/or in intradermal tests. Among the human AD criteria items, behavior corresponding to pruritus was observed in all 51 dogs. Skin lesions corresponding to eczematous dermatitis were seen in 50 dogs, and symmetrical distribution of skin lesions was noted in all 51 dogs. A chronic or chronically relapsing course was observed in 50 dogs. Based on these results, the concordance rate for the criteria was 96% (49/51). Differential diagnoses of AD were also investigated in the same manner. The concordance rate for the criteria was 0% (0/69) in scabies, 2% (1/50) in pyoderma, 0% (0/50) in demodicosis, 0% (0/9) in cutaneous lymphoma, 0% (0/2) in ichthyosis, 25% (2/7) in flea allergy, 48% (24/50) in seborrheic dermatitis and 75% (3/4) in food allergy. Canine AD is thus indicated as a valuable counterpart to human AD in clinical aspects. In addition, the human AD criteria could be applicable, with some modification, as provisional diagnostic criteria for canine AD. PMID:21434981

    Abstract Objective To describe the characteristics of patients who presented to outpatient sport and exercise medicine clinics with concussion. Design Retrospective chart review of electronic medical records. Setting Three specialized sport and exercise medicine clinics in London, Ont. Participants A total of 283 patients presenting with concussion. Main outcome measures Data collected included demographic variables (age and sex), sport participation at the time of injury, previous medical history (including history of concussion), Post-Concussion Symptom Scale (PCSS) scores, and return-to-play (RTP) variables (delay and outcome). Results The mean age of patients presenting for care was 17.6 years; 70.9% of patients were younger than 18 years of age (considered pediatric patients); 58.8% of patients were male; and 31.7% of patients had a previous history of concussion. The main sports associated with injury were hockey (40.0%), soccer (12.6%), and football (11.7%). Return to play was granted to 50.9% of patients before the 3-week mark and 80.2% of patients before 8 weeks. Total PCSS scores (maximum score was 132) and neck scores (part of the PCSS, maximum score was 6) were significantly higher in adults compared with pediatric patients (36.2 vs 27.6, P = .02, and 1.8 vs 1.2, P = .02, respectively). A significant difference was seen in RTP, with pediatric patients returning earlier than adults did (P = .04). This difference was not seen when comparing males with females (P = .07). Longer duration of follow-up did not influence RTP outcomes. Previous history of concussion was associated with restriction from contact or collision sports (P < .001). Conclusion Given the age and sex variability found in this study, as well as in previous published reports, it is important to manage each patient individually using current best available practice strategies to optimize long-term outcomes.

    This study aimed to explore the effects of the dipeptidyl peptidase-4 inhibitor sitagliptin and the biguanide metformin on the secretion of insulin and glucagon, as well as incretin levels, in Japanese subjects with type 2 diabetes mellitus poorly controlled with insulin monotherapy. This was a single-center, randomized, open-label, parallel group study, enrolling 25 subjects. Eleven patients (hemoglobin A1c [HbA1c] 8.40 ± 0.96%) and 10 patients (8.10 ± 0.54%) on insulin monotherapy completed 12-week treatment with sitagliptin (50 mg) and metformin (750 mg), respectively. Before and after treatment, each subject underwent a meal tolerance test. The plasma glucose, glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), C-peptide, and glucagon responses to a meal challenge were measured. HbA1c reductions were similar in patients treated with sitagliptin (0.76 ± 0.18%) and metformin (0.77 ± 0.17%). In the sitagliptin group, glucose excursion during a meal tolerance test was reduced and accompanied by elevations in active GLP-1 and active GIP concentrations. C-peptide levels were unaltered despite reduced glucose responses, while glucagon responses were significantly suppressed (-7.93 ± 1.95% of baseline). In the metformin group, glucose excursion and incretin responses were unaltered. C-peptide levels were slightly increased but glucagon responses were unchanged. Our data indicate that sitagliptin and metformin exert different effects on islet hormone secretion in Japanese type 2 diabetic patients on insulin monotherapy. A glucagon suppressing effect of sitagliptin could be one of the factors improving blood glucose control in patients inadequately controlled with insulin therapy. PMID:25328079

    We published a cardiac event risk score (CERS) predicting the risk of major cardiac events (MCEs) within 3 years. The purpose of this study was to verify the prognostic value of the CERS before and after treatment in Japanese patients with coronary artery disease.We retrospectively investigated 612 patients who underwent rest (201)Tl and stress (99m)Tc-tetrofosmin myocardial perfusion single photon emission computed tomography (SPECT) between October 2004 and March 2013 and who had a significant stenosis with ≥ 75% narrowing of the arterial diameter detected by coronary angiography performed after confirmation of ≥ 5% ischemia with the SPECT. The patients underwent treatment including revascularization and medication, and thereafter, were re-evaluated with SPECT during a chronic phase and followed-up to confirm prognosis for ≥ 1 year. The endpoint was the onset of MCEs during the follow-up.During the follow-up (36.7 ± 14.5 months), 50 patients (8.7%) experienced MCEs comprising cardiac death (n = 16), non-fatal myocardial infarction (n = 4), and unstable angina pectoris (n = 30). The multivariate Cox proportional hazards regression model analysis for the actual occurrence of MCEs showed the summed difference score % and MCE risks estimated with the CERS after treatment to be significant independent variables. Ischemic reduction after treatment contributed significantly to a decrease in the MCE risks. The MCE risks estimated with the CERS after treatment were generally consistent with the incidence of the MCEs actually observed.The CERS after treatment is a valuable formula for predicting prognosis in Japanese patients with coronary artery disease.

    Objective: Patients categorized Rutherford category IV might have different characteristics compared with Rutherford category V and VI. Our study aims were to estimate the clinical differences between Rutherford category IV and Rutherford category V and VI, for those underwent endovascular therapy for isolated infrapopliteal disease, and also to find risk factors for endovascular therapy in Rutherford category IV. Methods: Based on the Japanese multi-center registry data, 1091 patients with 1332 limbs (Rutherford category IV: 226 patients with 315 limbs, Rutherford category V and VI: 865 patients with 1017 limbs) were analyzed retrospectively. Results: Patients’ backgrounds and lesions’ characteristics had significant differences. Both freedom rate from major adverse limb event with perioperative death and amputation-free survival rate at 1 year were better in Rutherford category IV than Rutherford category V and VI (93.6% vs 78.3%, 87.7% vs 66.7%) and those maintained to 3 years (p < 0.0001). Significant predictors for major adverse limb event/perioperative death were small body mass index (<18.5 kg/m3) and initial endovascular therapy success, and those for amputation-free survival were small body mass index (<18.5 kg/m3), non-ambulatory status, high systematic inflammatory reaction (C-reactive protein > 3.0 mg/dL), chronic obstructive pulmonary disease, and coronary artery disease in Rutherford category IV. Conclusion: From the present results, Rutherford category IV should be recognized to have quite different backgrounds and better outcome from Rutherford category V and VI. PMID:26770796

    The Helsinki Declaration is a very important document regarding the protection of patients' rights in clinical trials and one of the fundamental sources of operational principles for every ethics committee. Although they have been updated, the international guidelines for ethics committees continually fail to address certain issues pertaining to the protection of patients' rights in clinical trials. These issues include, most significantly, the method of electing ethics committees (a free, secret ballot should be preferred to direct appointment), the avoidance of conflict of interest during the election of ethics committee members, and the necessary insurance coverage for the participants of clinical trials. Polish law should, on the other hand, be developed in such way as to not limit the effectiveness of ethics committees in protecting patients' rights in clinical trials. The ideal solution would be to draft a uniform law concerning not only clinical trials, but all medical experiments. The opinions of experts who have been reviewing medical research projects for several years may prove to be especially valuable in this setting. PMID:16501654

    2013-01-01

    Background Chronic obstructive pulmonary disease (COPD) is an important public health issue in many countries which is estimated to become the fifth cause of disability and the third cause of mortality in the world within 2020. The objective of this study was to identify the clinical characteristics in the real clinical practice of a sample of patients with COPD followed in a pulmonology clinic. Methods The initial sample contained 207 subjects with respiratory claims that searched for specialized treatment and initiated regular monitoring between 2004 and 2009 in a private clinic localized in Cascavel, in the state of Parana, Brazil. Demographic data (weight, height, body mass index - BMI), history of comorbidities, use of respiratory and non respiratory drugs were also registered. Results The main cause related to the development of COPD was current or prior smoking (92.0%); the most frequently reported symptom was dyspnea (95.0%), followed by cough (86.1%), wheezing (69.4%) and sputum production (40.0%). During the follow up, 51 patients developed the need for oxygen therapy (28.3%). In 96 patients, there were periods of acute exacerbation, resulting in 37 hospitalizations. In addition to COPD, a significant number of comorbidities were identified, being cardiovascular disease and neurological disorders the most prevalent ones. Conclusions Based on the data collected, we could outline the profile of patients with COPD, showing characteristics of an elderly population, with multiple comorbidities, suggesting a health related quality of life lower than expected.

    Background Because the prevalence and characteristics of primary headache have yet to be thoroughly studied in patients with hypersomnia disorders, including narcolepsy and idiopathic hypersomnia, we examined these parameters in the Japanese population. Methods In a multicentre cross-sectional survey, among 576 consecutive outpatients with sleep disorders, 68 narcolepsy patients and 35 idiopathic hypersomnia patients were included. Additionally, 61 healthy control subjects participated. Semi-structured headache questionnaires were administered to all participants. Results The patients with narcolepsy (52.9%) and idiopathic hypersomnia (77.1%) more frequently experienced headache than the healthy controls (24.6%; p<0.0001). The prevalence rates were 23.5%, 41.2% and 4.9% for migraine (p<0.0001) and 16.2%, 23.5% and 14.8% (p = 0.58) for tension-type headache among the narcolepsy patients, the idiopathic hypersomnia patients and the control subjects, respectively. Those who experienced migraine more frequently experienced excessive daytime sleepiness, defined as an Epworth Sleepiness Scale score of ≥10, than those who did not experience headache among the patients with narcolepsy (93.8% vs. 65.6%, p = 0.040) and idiopathic hypersomnia (86.7% vs. 37.5%, p = 0.026). Dream-enacting behaviour (DEB), as evaluated by the rapid eye movement sleep disorders questionnaire, was more frequently observed in the narcolepsy patients than in the idiopathic hypersomnia patients and the control subjects. An increased DEB frequency was observed in the narcolepsy patients with migraines compared to those without headache. Conclusions Migraines were frequently observed in patients with narcolepsy and idiopathic hypersomnia. DEB is a characteristic of narcolepsy patients. Further studies are required to assess the factors that contribute to migraines in narcolepsy and idiopathic hypersomnia patients. PMID:26418536

    Background In recent years, there has been increased interest in the subjective quality of life (QoL) of patients with bronchial asthma. QoL is a significant indicator guiding the efforts of professionals caring for patients, especially chronically ill ones. The identification of factors affecting the QoL reported by patients, despite their existing condition, is important and useful to provide multidisciplinary care for these patients. Aim To investigate the clinical factors affecting asthma patients’ QoL. Methods The study comprised 100 patients (73 female, 27 male) aged 18–84 years (mean age was 45.7) treated in the Allergy Clinic of the Wroclaw Medical University Department and Clinic of Internal Diseases, Geriatrics and Allergology. All asthma patients meeting the inclusion criteria were invited to participate. Data on sociodemographic and clinical variables were collected. In this study, we used medical record analysis and two questionnaires: the Asthma Quality of Life Questionnaire (AQLQ) to assess the QoL of patients with asthma and the Asthma Control Test to measure asthma control. Results Active smokers were shown to have a significantly lower QoL in the “Symptoms” domain than nonsmokers (P=0.006). QoL was also demonstrated to decrease significantly as the frequency of asthma exacerbations increased (R=−0.231, P=0.022). QoL in the domain “Activity limitation” was shown to increase significantly along with the number of years of smoking (R=0.404; P=0.004). Time from onset and the dominant symptom of asthma significantly negatively affected QoL in the “Activity limitation” domain of the AQLQ (R=−0.316, P=0.001; P=0.029, respectively). QoL scores in the “Emotional function” and “Environmental stimuli” subscale of the AQLQ decreased significantly as time from onset increased (R=−0.200, P=0.046; R=−0.328, P=0.001, respectively). Conclusion Patients exhibiting better symptom control have higher QoL scores. Asthma patients’ Qo

    Disorders of glucose metabolism, namely glucose intolerance and diabetes, are frequent in patients with chronic liver diseases. In patients with cirrhosis, diabetes can be either a classical type 2 diabetes mellitus or the so-called hepatogenous diabetes, i.e. a consequence of liver insufficiency and portal hypertension. This review article provides an overview of the possible pathophysiological mechanisms explaining diabetes in patients with cirrhosis. Cirrhosis is associated with portosystemic shunts as well as reduced hepatic mass, which can both impair insulin clearance by the liver, contributing to peripheral insulin resistance through insulin receptors down-regulation. Moreover, cirrhosis is associated with increased levels of advanced-glycation-end products and hypoxia-inducible-factors, which may play a role in the development of diabetes. This review also focuses on the clinical implications of diabetes in patients with cirrhosis. First, diabetes is an independent factor for poor prognosis in patients with cirrhosis. Specifically, diabetes is associated with the occurrence of major complications of cirrhosis, including ascites and renal dysfunction, hepatic encephalopathy and bacterial infections. Diabetes is also associated with an increased risk of hepatocellular carcinoma in patients with chronic liver diseases. Last, the management of patients with concurrent diabetes and liver disease is also addressed. Recent findings suggest a beneficial impact of metformin in patients with chronic liver diseases. Insulin is often required in patients with advanced cirrhosis. However, the favourable impact of controlling diabetes in patients with cirrhosis has not been demonstrated yet. PMID:26972930

    Aims and method A retrospective evaluation was undertaken of the clinical and economic effectiveness of three in-patient rehabilitation units across one London National Health Service trust. Information on admission days and costs 2 years before and 2 years after the rehabilitation placement, length of rehabilitation placement and the discharge pathway was collected on 22 service users. Results There were statistically significant reductions in hospital admission days in the 2 years following rehabilitation compared with the 2 years before, further reflected in significantly lower bed costs. Longer length of rehabilitation placement was correlated with fewer admission days after the placement. A substantial proportion of the sample went into more independent living, some with no further admissions at follow-up. Clinical implications The findings suggest that in-patient rehabilitation is both clinically and cost effective: if benefits are sustained they will offset the cost of the rehabilitation placement.

    As an alternative to the administrative and management views of clinical integration, the perceptions and current research of patients and their families about integration initiatives are presented at "ground zero," i.e., the caregiving level. If there is no integration at ground zero, the other levels are of little merit. Contrary to the pervading opinion, clinical integration is not a value-added endeavor to boost satisfaction scores of patients and families or to make a health care system look good to regulators. Rather, clinical integration is fundamental to the precision, efficiency, and effectiveness of care delivery. Examples of the need for integration spanning situations from critical care to self-care are described. PMID:11075183

    Gastric cancer is a leading cause of death worldwide. Nowadays, complete surgical resection and TNM at diagnosis are the main prognostic factors. In spite of this, many patients will have a recurrence after surgery and die within a few months or years. That means that we need more accurate prognostic factors to design specific approaches for individual patients. Chromosome instability is a feature of gastric cancer commonly associated to chromosomal aberrations that leads to major modifications of DNA content globally termed as aneuploidy. In this regard, many authors' opinions diverge regarding the clinical impact of aneuploidy. This review will summarise data on the clinical impact of aneuploidy on clinical practice, the biological mechanisms that underlie chromosomal instability that induces aneuploidy and the relevance of specific chromosomal aneuploidy to cancer biology.

    Introduction: Adrenocortical carcinoma (ACC) is a heterogeneous and rare disease. At presentation or at the time of a recurrence, the disease commonly spreads to the liver, lungs, lymph nodes, and bones. The brain has only rarely been reported as a site of metastases. Objective: The aims of this report were to describe the clinical characteristics of patients with ACC who developed brain metastasis and were evaluated at the National Cancer Institute. Methods: We describe the history and clinical presentation of six patients with ACC and metastatic disease in the brain. Images of the six patients and pathology slides were reviewed when available. Results: The median age at the time of the diagnosis of ACC was 42 years. The median time from the initial diagnosis until the presentation of brain metastasis was 43 months. As a group the patients had previously received multiples lines of chemotherapy (median of three), and they presented with one to three metastatic brain lesions. Four patients underwent metastasectomy, one had radiosurgery, and one had both modalities. Two patients are still alive, three died, between 2 and 14 months after the diagnosis of brain metastases, and one was lost to follow-up. Conclusion: Patients with advanced ACC can rarely present with metastasis to the brain, most often long after the initial diagnosis. Timely diagnosis of brain metastasis with appropriate intervention after discussion in a multidisciplinary meeting can improve the prognosis in this particular scenario. PMID:25412413

    Dystrophin is associated with several novel sarcolemmal proteins, including a laminin-binding extracellular glycoprotein of 156 kD (alpha-dystroglycan) and a transmembrane glycoprotein of 50 kD (adhalin). Deficiency of adhalin characterizes a severe autosomal recessive muscular dystrophy prevalent in Arabs. Here we report for the first time two mongoloid (Japanese) patients with autosomal recessive muscular dystrophy deficient in adhalin. Interestingly, adhalin was not completely absent and was faintly detectable in a patchy distribution along the sarcolemma in our patients. Although the M and B2 subunits of laminin were preserved, the B1 subunit was greatly reduced in the basal lamina surrounding muscle fibers. Our results raise a possibility that the deficiency of adhalin may be associated with the disturbance of sarcolemma-extracellular matrix interaction leading to sarcolemmal instability.

    Glucokinase is thought to play a glucose-sensor role in the pancreas, and abnormalities in its structure, function, and regulation can induce diabetes. The authors isolated the human glucokinase gene, and determined its genomic structure including exon-intron boundaries. Structure of the glucokinase gene in human was very similar to that in rat. Then, by screening Japanese diabetic patients using polymerase chain reaction - single strand conformation polymorphism (PCR-SSCP) and direct-sequencing strategies, they identified a missense mutation substituting ariginine (AGG) for glycine (GGG) at position 261 in exon 7 of the glucokinase gene in a patient with early-onset non-insulin-dependent diabetes (NIDDM). 12 refs., 3 figs., 2 tabs.

    Chronic obstructive pulmonary disease (COPD) is a progressive disease, its prevalence increases with age. COPD is frequently associated with co-morbidities such as cognitive impairment, and their clinical relevance has risen in the recent past. Cognitive function may fluctuate with the variable components of COPD like hypoxaemia, hypercapnia, lung function, exacerbations or severity of the disease. The objectives of this study were to examine whether the cognitive status of COPD patients is different across clinical stages (exacerbation, at discharge and stable COPD) and also if there are cognitive areas that have more potential to change than others. Prospective observational clinical study: 62 patients admitted to hospital due to acute exacerbation of COPD were evaluated at hospital admission; 61 at discharge; and finally, 48 patients with stable COPD completed the study and were included in the analysis. Cognitive status was assessed with the Montreal Cognitive Assessment (MoCA). Our results show that all clinical variables improved from exacerbation to discharge COPD. MoCA total score, visuoconstructional, attention, language, abstraction, delayed recall and orientation subscores improved significantly from exacerbation to discharge COPD (p < 0.05). MoCA total score, visuoconstructional and naming subscores worsened significantly from discharge to stable COPD (p < 0.05). Finally, from exacerbation to stable COPD all the clinical variables improved; MoCA total score and naming, attention, language, abstraction and delayed recall subscores have shown significant differences (p < 0.05). Cognitive status of COPD patients is different across clinical stages, and there are cognitive areas with more potential to change than others. PMID:26667660

    After a review of the clinical studies on the treatment of diabetic patients with pantethine, the authors discuss the results obtained in a postmarketing surveillance (PMS) study on 1045 hyperlipidemic patients receiving pantethine (900 mg/day on average). Of these patients, 57 were insulin-dependent (Type I) and 241 were non insulin-dependent (Type II) diabetics. Beyond the epidemiological considerations made possible by a PMS study, the authors show that pantethine brought about a statistically significant and comparable improvement of lipid metabolism in the three groups of patients, with very good tolerability. Pantethine should therefore be considered for the treatment of lipid abnormalities also in patients at risk such as those with diabetes mellitus. PMID:2524328

A total of 334 isolates, 316 episodes, and 305 patients were included, corresponding to 2/3 of the national episodes. Blood culture positivity varied by system, species, and procedure. Thus, cases with concomitant bacteremia were reported less commonly by BacT/Alert than by the Bactec system (9% [11/124 cases] versus 28% [53/192 cases]; P < 0.0001), and cultures with Candida glabrata or those drawn via arterial lines needed longer incubation. Species distribution varied by age, prior antifungal treatment (57% occurrence of C. glabrata, Saccharomyces cerevisiae, or C. krusei in patients with prior antifungal treatment versus 28% occurrence in those without it; P = 0.007), and clinical specialty (61% occurrence of C. glabrata or C. krusei in hematology wards versus 27% occurrence in other wards; P = 0.002). Colonization samples were not predictive for the invasive species in 11/100 cases. Fifty-six percent of the patients had undergone surgery, 51% were intensive care unit (ICU) patients, and 33% had malignant disease. Mortality increased by age (P = 0.009) and varied by species (36% for C. krusei, 25% for C. parapsilosis, and 14% for other Candida species), severity of underlying disease (47% for ICU patients versus 24% for others; P = 0.0001), and choice but not timing of initial therapy (12% versus 48% for patients with C. glabrata infection receiving caspofungin versus fluconazole; P = 0.023). The initial antifungal agent was deemed suboptimal upon species identification in 15% of the cases, which would have been 6.5% if current guidelines had been followed. A large proportion of Danish fungemia patients were severely ill and received suboptimal initial antifungal treatment. Optimization of diagnosis and therapy is possible. PMID:21715585

    Klinefelter syndrome, with an incidence of 1:600 male newborns, is the most frequent form of male hypogonadism. However, despite its relatively high frequency, the syndrome is often overlooked. To prevent such oversights, the clinical features should be better characterized, and simple screening tests should be used more frequently. In a cohort of 309 patients suspected of having Klinefelter syndrome, we evaluated the clinical symptoms as well as the diagnostic value of the Barr body test for screening procedures. On the basis of chromosome analysis, 85 patients (group I) were diagnosed as having Klinefelter syndrome, and 224 patients had a 46,XY karyotype (group II). Barr body analysis revealed a specificity of 95% and a sensitivity of 82% for the diagnosis of Klinefelter syndrome. General features (eg, reason for admission, age, age of the parents, body weight, and frequency of maldescended testes) were not different between the groups, except that group I had a higher proportion of patients with a lower educational background. Compared to group II, patients with Klinefelter syndrome were taller (P <.001); had smaller testis volumes (P <.0001), higher follicle-stimulating hormone (FSH) and luteinizing hormone (LH) values; and carried a tendency for less androgenic phenotype and secondary hair distribution. Testosterone, estradiol, sex hormone-binding globulin (SHBG), and prostate-specific antigen (PSA) serum levels as well as prostate volume were not significantly different between the groups. In patients who provided an ejaculate, azoospermia was found in 54% of the patients in group II and in 93% of the patients with Klinefelter syndrome. Although not exclusively characteristic for Klinefelter syndrome, the combination of low testicular volume and azoospermia, together with elevated gonadotropins, is highly indicative for a Klinefelter syndrome and should stimulate further clinical investigations. Barr body analysis provides a quick and reliable screening test

    The aim of this study was to evaluate the clinical, laboratory findings and therapeutic features of patients with brucellosis. The diagnosis was made by clinical findings, automated blood culture, serology (Rose Bengal plate agglutination test, standard tube agglutination (Wright) and immunofluorerescence). The susceptibility of 13 strains was tested in vitro. The base sequence was determined for four strains. Forty-five cases were collected (31 acute and 14 sub-acute). Contamination was digestive in 62%. Symptoms of patients were fever (93%), sweating (82%), arthralgia (78%) and splenomegaly (51%). Elevated erythrocyte sedimentation rate was determined in 80%, leukopenia in 49% and anaemia in 37% of cases. Blood cultures were positives in 39% of cases. The four sequenced strains were identified as Brucella melitensis biovar abortus. Six strains were resistant to sufomethoxazol-trimetoprim (54%). In 93% of cases, the treatment was associated rifampicin and doxycyclin. One patient died. No relapse was reported. PMID:18387752

  16. Principal results of the Japanese trial to assess optimal systolic blood pressure in elderly hypertensive patients (JATOS).

    PubMed

    2008-12-01

    The benefits of lowering a systolic blood pressure below 140 mmHg in elderly hypertension remain controversial. This study is a prospective, randomized, open-label study with blinded assessment of endpoints to compare the 2-year effect of strict treatment to maintain systolic blood pressure below 140 mmHg with that of mild treatment to maintain systolic blood pressure below 160 but at or above 140 mmHg in elderly hypertensive patients. Patients with essential hypertension (65-85 years old, with a pretreatment systolic blood pressure of above 160 mmHg) were randomly assigned to receive strict treatment (n=2,212) or mild treatment (n=2,206). The baseline drug was efonidipine hydrochloride, a long-acting calcium antagonist. The primary endpoint was the combined incidence of cardiovascular disease and renal failure, and the secondary endpoints were total deaths and any safety problems. Although final blood pressures (systolic/diastolic) were significantly lower in the strict-treatment group compared with the mild-treatment group (135.9/74.8 vs. 145.6/78.1 mmHg; p<0.001), the incidence of the primary endpoint was similar in the two groups (86 patients in each group; p=0.99). Total deaths were 54 in the strict-treatment group vs. 42 in the mild-treatment group (p=0.22), and treatment was withdrawn because of adverse events in 36 patients in each group (p=0.99). An interaction between age and treatment for the primary endpoints (p=0.03) was seen. Complex clinical features associated with aging seem to have obscured the difference in effect between the two treatments. Further studies are needed to assess the optimal treatment strategy for hypertension in the elderly. PMID:19139601

    For chronic hepatitis C virus (HCV) infection, evaluation of response to peginterferon (PEG-IFN) plus ribavirin (RBV) therapy based on viral kinetics is useful as an early predictor of treatment efficacy, but the underlying mechanisms of the different viral kinetics to treatment are still unclear. The response to 48-week PEG-IFN-RBV combination therapy was evaluated in 160 Japanese adult patients infected with HCV genotype 1b and determined the rapid virological response (at 4 weeks), early virological response (at 12 weeks), end-of treatment response, and sustained virological response (6 months after end of treatment). The proportion of patients who showed rapid, early and sustained virological, and end-of treatment responses were 50%, 73%, 47%, and 71%, respectively. Furthermore, 66% of patients who achieved early virological response also showed sustained virological response. Multivariate analysis identified substitutions of amino acid (aa) 70 and 91 in the HCV core region (double-wild-type) as a predictor of early HCV-RNA negativity, rapid, early, and sustained virological responses and end-of treatment response, and lipid metabolic factors (high levels of LDL cholesterol and total cholesterol) as predictors of early and rapid virological responses and end-of treatment response. Male sex and low levels of alpha-fetoprotein were other predictors of sustained virological response. Furthermore, female sex and severity of liver fibrosis were determinants of lack of sustained virological response in spite of early virological response. This study identified predictors of efficacy of PEG-IFN-RBV therapy based on viral kinetics in Japanese patients infected with HCV genotype 1b. PMID:17854035

    This study aims to compare maternal uniparental disomy 15 (mUPD) and a paternal deletion of 15q11-13 (DEL) of Prader-Willi syndrome (PWS) in regard to autism spectrum disorders (ASD). Forty-five Japanese individuals with PWS were recruited from a single recruitment center. The participants consisted of 22 children (aged from 6 to 12) and 23 adolescents (aged from 13 to 19). Six children and seven adolescents were confirmed as having mUPD. Sixteen children and 16 adolescents were confirmed as having DEL. Under blindness to the participants' genotypes, a single psychologist carried out behavioral and psychological assessments, including the Wechsler Intelligence Scales, Pervasive Developmental Disorders Autism Society Japan Rating Scale (PARS), and ADHD-Rating Scale-IV (ADHD-RS-IV). Two comparisons were made: one between mUPD and DEL children and another between mUPD and DEL adolescents. In children, no significant differences were found between mUPD and DEL participants in terms of autistic (PARS childhood, P = 0.657) and impulsive behaviors (ADHD-RS-IV hyperactive/impulsive, P = 0.275). In adolescents, mUPD patients showed significantly more autistic symptomatology (PARS adolescent, P = 0.027) and significantly more impulsive behavior (ADHD-RS-IV hyperactive/impulsive, P = 0.01) than DEL patients. Our findings about Japanese PWS patients were consistent with previous researches from western countries not focused on Asian patients, indicating that mUPD cases would be more prone to ASD than DEL cases, regardless of ethnoregional differences. In addition, our data suggested that the behavioral difference between mUPD and DEL cases in terms of autistic and impulsive symptoms tend to be unrecognizable in their childhood. PMID:24850752

    Objectives. To demonstrate the pharmacokinetic equivalence of CT-P13 and its innovator infliximab (IFX) in Japanese patients with rheumatoid arthritis (RA), and to compare the efficacy and safety of these drugs, administered for 54 weeks. Methods. In a randomized, double-blind, parallel-group, multicenter study, 3 mg/kg of CT-P13 or IFX, in combination with methotrexate (MTX) (6–16 mg/week), was administered for 54 weeks to Japanese active RA patients with an inadequate response to MTX, to demonstrate the pharmacokinetic equivalence, based on the area under the curve (AUCτ) (weeks 6–14) and Cmax (week 6) of these drugs, and to compare their efficacy and safety. Results. The CT-P13-to-IFX ratios (90% confidence intervals) of the geometric mean AUCτ and Cmax values in patients negative for antibodies to infliximab at week 14 were 111.62% (100.24–124.29%) and 104.09% (92.12–117.61%), respectively, demonstrating the pharmacokinetic equivalence of these drugs. In the full analysis set, CT-P13 and IFX showed comparable therapeutic effectiveness, as measured by the American College of Rheumatology, Disease Activity Score in 28 joints, the European League Against Rheumatism, and other efficacy criteria, at weeks 14 and 30. The incidence of adverse events was similar for these drugs. Conclusion. CT-P13 and IFX, administered at a dose of 3 mg/kg in combination with MTX to active RA patients, were pharmacokinetically equivalent and comparable in efficacy and safety. PMID:25736355

    Aims. Efficacy and safety of DPP-4 inhibitor, sitagliptin, add-on therapy to insulin were investigated in Japanese patients with type 2 diabetes. Subjects and Methods. Two hundred and sixteen patients (126 men, 65 ± 12 years old, BMI 24.9 ± 4.5, means ± S.D.) who had been treated by insulin alone or insulin combined with other oral hypoglycemic agents (OHAs) were recruited, and sitagliptin was added for 3 months. Results. HbA1c was significantly decreased after 3 months of add-on therapy as a whole (8.56 ± 1.50% to 7.88 ± 1.25%, P < 0.0001). Body weight did not change and insulin dosage was significantly (P < 0.0001) decreased for 3 months. Furthermore, day-to-day glucose variability was significantly reduced (18.3 ± 9.1 to 16.1 ± 8.1%, P < 0.05). In stepwise multiple regression analysis on ΔHbA1c as an outcome variable, the higher baseline HbA1c value and a preserved CPR were selected as significant predictive variables. Fifteen patients complained of mild hypoglycemia without any assistance during 3 months of sitagliptin add-on, while no severe hypoglycemic episode was reported. Conclusions. Add-on of sitagliptin to ongoing insulin therapy effectively reduced either HbA1c level or glucose fluctuation and could be a practical and well-tolerated alternative to treat Japanese patients with type 2 diabetes who had been inadequately controlled by insulin with or without other OHAs.

    This paper presents an analysis of a residency primary care clinic whose majority of patients are underserved. The clinic is operated by the health system for Bexar County and staffed primarily with physicians in a three-year Family Medicine residency program at The University of Texas School of Medicine in San Antonio. The objective of the study was to obtain a better understanding of patient flow through the clinic and to investigate changes to current scheduling rules and operating procedures. Discrete event simulation was used to establish a baseline and to evaluate a variety of scenarios associated with appointment scheduling and managing early and late arrivals. The first steps in developing the model were to map the administrative and diagnostic processes and to collect time-stamped data and fit probability distributions to each. In conjunction with the initialization and validation steps, various regressions were performed to determine if any relationships existed between individual providers and patient types, length of stay, and the difference between discharge time and appointment time. The latter two statistics along with resource utilization and closing time were the primary metrics used to evaluate system performance.The results showed that up to an 8.5 % reduction in patient length of stay is achievable without noticeably affecting the other metrics by carefully adjusting appointment times. Reducing the no-show rate from its current value of 21.8 % or overbooking, however, is likely to overwhelm the system's resources and lead to excessive congestion and overtime. Another major finding was that the providers are the limiting factor in improving patient flow. With an average utilization rate above 90 % there is little prospect in shortening the total patient time in the clinic without reducing the providers' average assessment time. Finally, several suggestions are offered to ensure fairness when dealing with out-of-order arrivals. PMID:25155098

    Background A new area of interest in the search for biomarkers for schizophrenia is the study of the acoustic parameters of speech called 'speech signal features'. Several of these features have been shown to be related to emotional responsiveness, a characteristic that is notably restricted in patients with schizophrenia, particularly those with prominent negative symptoms. Aim Assess the relationship of selected acoustic parameters of speech to the severity of clinical symptoms in patients with chronic schizophrenia and compare these characteristics between patients and matched healthy controls. Methods Ten speech signal features-six prosody features, formant bandwidth and amplitude, and two spectral features-were assessed using 15-minute speech samples obtained by smartphone from 26 inpatients with chronic schizophrenia (at enrollment and 1 week later) and from 30 healthy controls (at enrollment only). Clinical symptoms of the patients were also assessed at baseline and 1 week later using the Positive and Negative Syndrome Scale, the Scale for the Assessment of Negative Symptoms, and the Clinical Global Impression-Schizophrenia scale. Results In the patient group the symptoms were stable over the 1-week interval and the 1-week test-retest reliability of the 10 speech features was good (intraclass correlation coefficients [ICC] ranging from 0.55 to 0.88). Comparison of the speech features between patients and controls found no significant differences in the six prosody features or in the formant bandwidth and amplitude features, but the two spectral features were different: the Mel-frequency cepstral coefficient (MFCC) scores were significantly lower in the patient group than in the control group, and the linear prediction coding (LPC) scores were significantly higher in the patient group than in the control group. Within the patient group, 10 of the 170 associations between the 10 speech features considered and the 17 clinical parameters considered were

    The United Nations and World Health Organisation have identified autism spectrum disorder (ASD) as an important public health issue across global mental health services. Although a range of tools exist to identify and quantify ASD symptoms, there is a lack of information about which ASD measures are used in different services worldwide. This paper presents data from a large survey of measures used for patient characterisation in major ASD research and clinical centres across Europe collected between June 2013 and January 2014. The objective was to map the use of different instruments used to characterise ASD, comorbid psychopathology and cognitive and adaptive ability for patient diagnostic and characterisation purposes across Europe. Sixty-six clinical research sites diagnosing 14,844 patients per year contributed data. The majority of sites use the well-established Autism Diagnostic Observation Schedule (ADOS) and the Autism Diagnostic Interview (ADI) instruments, though the proportion of sites in Western Europe using the ADI was almost double the rate in Eastern Europe. Approximately half the sites also used the Social Communication Questionnaire (SCQ) and Social Responsiveness Scale (SRS), although use of the SRS was over three times higher in Western Europe compared with Eastern Europe. The use of free/open access measures was lower than commercially available tools across all regions. There are clinical and scientific benefits in encouraging further convergence of clinical characterisation measures across ASD research and clinical centres in Europe to facilitate large-scale data sharing and collaboration, including clinical trials of novel medications and psychological interventions.

    Objectives: To identify clinical predictors of suicide attempts in patients with bipolar disorder. Methods: This study included bipolar patients who were treated in the Psychiatry Department, Haseki Training and Research Hospital, Istanbul, Turkey, between 2013 and 2014; an informed consent was obtained from the participants. Two hundred and eighteen bipolar patients were assessed by using the structured clinical interview for Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) Axis-I (SCID-I) in order to detect all possible psychiatric comorbid diagnoses. Clinical predictors of suicide attempts were examined in attempters and non-attempters. The study design was retrospective. Results: The lifetime suicide attempt rate for the entire sample was 19.2%. Suicide attempters with bipolar disorder had more lifetime comorbidity of eating disorder. Female gender and family history of mood disorder were significant predictors for suicide attempts. There was no difference between groups in terms of bipolar disorder subtype, onset age of bipolar disorder, total number of episodes, first and predominant episode type, suicide history in first degree relatives, severity of episodes, and hospitalization and being psychotic. Conclusion: Our study revealed that female gender, family history of mood disorder, and eating disorder are more frequent in bipolar patients with at least one suicide attempt. PMID:27279513

    OBJECTIVES: To evaluate the clinical outcomes and identify the predictors of mortality in elderly patients undergoing peritoneal dialysis. METHODS: We conducted a retrospective study including all incident peritoneal dialysis cases in patients ≥65 years of age treated from 2001 to 2014. Demographic and clinical data on the initiation of peritoneal dialysis and the clinical events during the study period were collected. Infectious complications were recorded. Overall and technique survival rates were analyzed. RESULTS: Fifty-eight patients who began peritoneal dialysis during the study period were considered for analysis, and 50 of these patients were included in the final analysis. Peritoneal dialysis exchanges were performed by another person for 65% of the patients, whereas 79.9% of patients preferred to perform the peritoneal dialysis themselves. Peritonitis and catheter exit site/tunnel infection incidences were 20.4±16.3 and 24.6±17.4 patient-months, respectively. During the follow-up period, 40 patients were withdrawn from peritoneal dialysis. Causes of death included peritonitis and/or sepsis (50%) and cardiovascular events (30%). The mean patient survival time was 38.9±4.3 months, and the survival rates were 78.8%, 66.8%, 50.9% and 19.5% at 1, 2, 3 and 4 years after peritoneal dialysis initiation, respectively. Advanced age, the presence of additional diseases, increased episodes of peritonitis, the use of continuous ambulatory peritoneal dialysis, and low albumin levels and daily urine volumes (<100 ml) at the initiation of peritoneal dialysis were predictors of mortality. The mean technique survival duration was 61.7±5.2 months. The technique survival rates were 97.9%, 90.6%, 81.5% and 71% at 1, 2, 3 and 4 years, respectively. None of the factors analyzed were predictors of technique survival. CONCLUSIONS: Mortality was higher in elderly patients. Factors affecting mortality in elderly patients included advanced age, the presence of comorbid

    The objective of this study was to characterize changes in the quality of life (QOL) of Japanese patients following robot-assisted radical prostatectomy (RARP). This study included 298 consecutive localized prostate cancer (PC) patients undergoing RARP. The health-related QOL and disease-specific QOL were assessed using The Medical Outcomes Study 8-Item Short Form (SF-8) and The Extended Prostate Cancer Index Composite (EPIC), respectively, before and 1, 3, 6, 12 and 24 months after RARP. At 1 month after RARP, four (physical function, role limitations because of physical health problems, social function and role limitations because of emotional problems) of the eight scores in SF-8 were significantly impaired compared with those of baseline scores. However, all eight scores on all postoperative assessments, except for at 1 month after RARP, showed no significant differences from baseline scores. Although there were no significant differences in the bowel function, bowel bother, sexual bother, hormonal function or hormonal bother between baseline and postoperative assessments of EPIC at all time points, the urinary function, urinary incontinence and sexual function scores at 1, 3 and 6 months after RARP were significantly inferior to those of baseline scores, and urinary bother and urinary irritation/obstruction scores at 1 month after RARP were significantly impaired compared with those of baseline scores. These findings suggest that the health-related QOL of Japanese PC patients undergoing RARP may not be markedly deteriorated following RARP; however, as for the disease-specific QOL, urinary and sexual functions, particularly those early after RARP, appeared to be significantly impaired.

    Objective To assess clinical characteristics, treatment and survival of patients with uveal melanoma in China. Methods The retrospective study included all patients with malignant uveal melanoma who were consecutively examined in the study period from January 2005 and June 2015 in the Beijing Tongren hospital. Results The mean age of the 582 patients (295(50.7%) women) was 44.6±12.6 years (range:5–77 years). The tumors were located most often in the superior temporal region (in 117(21.5%) patients) and least common in the inferior region (in 31(5.7%) patients). In 548(94.2%) patients, the tumors were located in the choroid, in 33(5.7%) patients in the ciliary body, and in one (0.2%) patient in the iris. Treatment included episcleral brachytherapy (415(71.3%) patients), local tumor resection (48(8.2%) patients) and primary enucleation (119(20.4%) patients). In 53 individuals out of the 415 patients with primary brachytherapy, episcleral brachytherapy was followed by enucleation, due to an increasing tumor size or due to uncontrolled neovascular glaucoma. Median follow-up time was of 30 months (range: 1–124 months; mean: 34.8 ± 24.4 months). Overall survival rate at 5 and 10 years was of 92.7% and 85.1%. Younger age (P = 0.017), tumor location in the nasal meridian(P = 0.004), smaller tumor size (P<0.001), hemispheric tumor shape (P = 0.025), histological tumor cell type (spindle-cell type versus epitheloid cell type;P = 0.014), and type of treatment (episcleral brachytherapy versus local tumor resection and versus primary enucleation; P<0.001) were significantly associated with the overall survival in univariate analysis, while in multivariate analysis only smaller tumor size was significantly (P<0.001; RR: 4.75; 95% confidence interval:2.11,10.7) associated with better overall survival. Conclusions In this study on clinical characteristics of uveal melanoma of a larger group of patients from China, the onset age was considerably younger and survival rate

    A patient-centered paradigm for clinical research and medical care is presented as a solution to the problem of declining innovation and increasing costs and development time in the pipeline for new therapies. Fundamental differences in values and motivations among scientists, clinicians, industry sponsor, and patients in neurotherapeutics provide a framework for analysis of ethical conflicts and the loss of public confidence in medical research. Parkinson advocates' views on clinical trial participation, perceived risks and benefits, placebo controls, and sham surgery are presented. These views reflect the sense of urgency and the unique perspective that comes from living with this progressive, debilitating condition full time. A patient-centered paradigm that includes authentic voices of patients as collaborators at every stage of development will help to resolve conflicts, build trust, recruit trial participants, and accelerate new therapies. Key elements are adaptive clinical trial methods and the development of information technology for the assessment of outcomes and surveillance of safety over the life cycle of a medical product. Supported by the Parkinson's Disease Foundation, the Parkinson Pipeline Project is a grassroots group of Parkinson's patients whose goal is to represent an authentic voice for patients in the treatment development process. This group promotes education and communication between members of the Parkinson's community and active stakeholders in medical research, industry, and regulatory agencies. Its members are an example of a new breed of knowledgeable consumers, armed with first-hand access to research findings and reinforced by on-line connections to like-minded peers throughout the world.

Patients and Methods One thousand consecutive patients with primary myelofibrosis seen at Mayo Clinic between November 4, 1977, and September 1, 2011, were considered. The International Prognostic Scoring System (IPSS), dynamic IPSS (DIPSS), and DIPSS-plus were applied for risk stratification. Separate analyses were included for patients seen at time of referral (N=1000), at initial diagnosis (N=340), and within or after 1 year of diagnosis (N=660). Results To date, 592 deaths and 68 leukemic transformations have been documented. Parameters at initial diagnosis vs time of referral included median age (66 vs 65 years), male sex (61% vs 62%), red cell transfusion need (24% vs 38%), hemoglobin level less than 10 g/dL (38% vs 54%), platelet count less than 100 × 109/L (18% vs 26%), leukocyte count more than 25 × 109/L (13% vs 16%), marked splenomegaly (21% vs 31%), constitutional symptoms (29% vs 34%), and abnormal karyotype (31% vs 41%). Mutational frequencies were 61% for JAK2V617F, 8% for MPLW515, and 4% for IDH1/2. DIPSS-plus risk distributions at time of referral were 10% low, 15% intermediate-1, 37% intermediate-2, and 37% high. The corresponding median survivals were 17.5, 7.8, 3.6, and 1.8 years vs 20.0, 14.3, 5.3, and 1.7 years for patients younger than 60 years of age. Compared with both DIPSS and IPSS, DIPSS-plus showed better discrimination among risk groups. Five-year leukemic transformation rates were 6% and 21% in low- and high-risk patients, respectively. Conclusion The current document should serve as a valuable resource for patients and physicians and provides context for the design and interpretation of clinical trials. PMID:22212965

    Background Although patient satisfaction ratings often drive positive changes, they may have unintended consequences. Objective The study reported here aimed to evaluate the clinician-perceived effects of patient satisfaction ratings on job satisfaction and clinical care. Methods A 26-item survey, developed by a state medical society in 2012 to assess the effects of patient satisfaction surveys, was administered online to physician members of a state-level medical society. Respondents remained anonymous. Results One hundred fifty five physicians provided responses (3.9% of the estimated 4,000 physician members of the state-level medical society, or approximately 16% of the state’s emergency department [ED] physicians). The respondents were predominantly male (85%) and practicing in solo or private practice (45%), hospital (43%), or academia (15%). The majority were ED (57%), followed by primary care (16%) physicians. Fifty-nine percent reported that their compensation was linked to patient satisfaction ratings. Seventy-eight percent reported that patient satisfaction surveys moderately or severely affected their job satisfaction; 28% had considered quitting their job or leaving the medical profession. Twenty percent reported their employment being threatened because of patient satisfaction data. Almost half believed that pressure to obtain better scores promoted inappropriate care, including unnecessary antibiotic and opioid prescriptions, tests, procedures, and hospital admissions. Among 52 qualitative responses, only three were positive. Conclusion These pilot-level data suggest that patient satisfaction survey utilization may promote, under certain circumstances, job dissatisfaction, attrition, and inappropriate clinical care among some physicians. This is concerning, especially in the context of the progressive incorporation of patient satisfaction ratings as a quality-of-care metric, and highlights the need for a rigorous evaluation of the optimal methods

    Clinical samples from immunocompromised patients were screened for polyomaviral sequences by nested polymerase chain reaction (PCR) to evaluate the association of these viral infections with progressive multifocal leukoencephalopathy (PML). JC virus (JCV) DNA was detected in 19 of 23 CSF samples and all four brain samples from patients with PML. Neither BK virus (BKV) nor simian virus 40 (SV40) DNA were detected in these samples. No evidence was found to support the hypothesis that polyomaviral DNA is present in the central nervous system of immunosuppressed patients without PML (CSF n = 67, brain n = 19). JCV DNA was not detected in any peripheral blood sample included in this study. JCV DNA was detected in urine from three of eight patients with PML, but was also amplified from three of 29 urine samples from patients without PML, JCV, and not SV40 or BKV, was associated with PML in this study.

    Inflammatory bowel diseases have a natural course characterized by alternating periods of remission and relapse. Disease flares occur in a random way and are currently unpredictable for the most part. Predictors of benign or unfavourable clinical course are required to facilitate treatment decisions and to avoid overtreatment. The present article provides a literature review of the current evidence on the main clinical, genetic, endoscopic, histologic, serologic and fecal markers to predict aggressiveness of inflammatory bowel disease and discuss their prognostic role, both in Crohn’s disease and ulcerative colitis. No single marker seems to be reliable alone as a flare predictor, even in light of promising evidence regarding the role of fecal markers, in particular fecal calprotectin, which has reported good results recently. In order to improve our daily clinical practice, validated prognostic scores should be elaborated, integrating clinical and biological markers of prognosis. Finally, we propose an algorithm considering clinical history and biological markers to intercept patients with high risk of clinical relapse. PMID:26811644

    Deaths due to airway obstruction are more common in psychiatric inpatients than in the normal population. A dysphagia program was started in a 400 bed Massachusetts psychiatric hospital after 4 patients in 1 year died from asphyxia. In the year after the program was started, there were no deaths; however, 28 patients experienced 32 choking incidents. The 28 patients received clinical evaluations by speech pathologists, neurologists, psychiatrists, and internists. Of the incidents, 55% required use of the Heimlich maneuver to open the airway. Choking incidents could be classified into five types based on results of clinical examination: bradykinetic, dyskinetic, fast eating syndrome, paralytic, and medical. Twenty-one of the 28 patients were studied by videofluoroscopy and 86% of the videos were abnormal, showing aspiration in eight, webs in five, and delay in the oral phase in five. Patients with bradykinetic dysphagia (secondary to neuroleptic-induced extra-pyramidal syndrome [EPS]) and paralytic dysphagia appeared to experience a more severe form of choking. PMID:1884635

    Neurocysticercosis (NCC) is a common parasitic disease in our region, presenting diversity of neurological symptoms and signs. The present study has as primary objective an evaluation of the NCC's clinical and epidemiological profile within Bahia State, by means of a prospective study of 220 patients diagnosed from March 1988 to March 1999, with a follow-up of six months. Exams, such as Computed Cranial Tomography Scan (CT), Cerebral Spine Fluid (CSF) and Electroencephalogram (EEG), were accomplished in three distinct moments of these patients' evolution: at starting or diagnostic point (zero time), at after-intervention period (one month after treatment), and at control period (six months after treatment).

    End-of-life issues have become an urgent problem in Japan, where people are among the longest lived in the world and most of them die while connected to high-technology medical equipment. This study examines a sensitive end-of-life ethical issue that concerns patients, families and nurses: the withdrawal of artificial food and fluid from terminally ill patients. A sample of 160 Japanese nurses, who completed a questionnaire that included forced-choice and open-ended questions, supported this act under only two specific conditions: if the patient requested it, and if it relieved the patient's suffering. They considered that the doctor's orders, the family's request, or the patient's advanced age did not ethically justify this act. A small number of people who had recently lost a relative took part in semistructured interviews focusing on their experiences of their terminally ill relatives being given artificial food and fluid. Ethical, social and cultural factors surrounding this issue are discussed. PMID:16010894

    The Patient-Centered Outcomes Research Institute (PCORI) recently launched PCORnet to establish a single inter-operable multicenter data research network that will support observational research and randomized clinical trials. This paper provides an overview of the patient-powered research networks (PPRNs), networks of patient organizations focused on a particular health condition that are interested in sharing health information and engaging in research. PPRNs will build on their foundation of trust within the patient communities and draw on their expertise, working with participants to identify true patient-centered outcomes and direct a patient-centered research agenda. The PPRNs will overcome common challenges including enrolling a diverse and representative patient population; engaging patients in governance; designing the data infrastructure; sharing data securely while protecting privacy; prioritizing research questions; scaling small networks into a larger network; and identifying pathways to sustainability. PCORnet will be the first distributed research network to bring PCOR to national scale. PMID:24821741

    The contribution of the tumour necrosis factor (TNF) B + 252 (TNFB) dimorphism and microsatellite polymorphisms of TNFa and TNFb to the pathogenesis of systemic lupus erythematosus (SLE) was studied in Japanese patients. The TNFB dimorphism was determined using the restriction fragment length polymorphism (RFLP) method with NcoI digestion followed by specific polymerase chain reaction (PCR) amplification. TNFa and TNFb microsatellite polymorphisms were determined using the DNA sequencer and GeneScan program (Applera Corporation, Foster City, CA) followed by specific PCR amplification. HLA-DRB1*15 typing was carried out by the PCR-sequence specific conformational polymorphism (SSCP) method. In SLE, the allele frequency of TNFB*2 significantly increased (68.9%, P < 0.05) and the genotype frequency of TNFB*2/2 also increased (52.8%, P < 0.05). TNFB*2 showed no significant linkage disequilibrium with HLA-DRB1*1501. The prevalence of TNFa13 and TNFb4 showed very slight increases, but these increases were not significant. An association analysis indicated that TNFB*2/2 conferred greater, or at least equal, susceptibility to SLE in Japanese patients in comparison with HLA-DRB1*1501. The TNFB*2/2 genotype may contribute additively with DRB1*1501 to SLE in Japanese patients. No association was observed between auto-antibodies and TNF. TNFB*2 is a genetic marker for SLE in Japanese patients, while TNFa and TNFb microsatellites are not associated with SLE. PMID:15932622

  1. Further reflections on the impact of clinical writing on patients.

    2006-06-01

    Though it is unlikely that instituting universal guidelines will ever be possible for patient approval of the analyst's use of clinical material outside of the treatment setting, the author offers some supplementary reflections to those already available in the literature. Broadly applied informed consent guidelines would increase the distortion that already exists in our clinical literature due to self-imposed restraints by writers. Moreover, the powerful irrational forces mobilized by consent in the dyad are not easily 'held' by traditional applicable legal categories. Metapsychological formulations of the intrapsychic and intersubjective impact of patient participation in the writing process on individual analytic dyads are needed. Notions of privacy protection, validation, dyadic co-construction, or writing-as-containment by a third as rationales for informed consent fail to encompass the transindividual and external sources of human identity and the ineradicable lack of unity in the unconscious. Nevertheless, theoretical affinity and preferred technique may be mediating factors in positive outcomes of the consent process. Some paradigms not only accommodate more comfortably but also actively seek the intersubjective repercussions of informed consent. As an alternative or complementary viewpoint, the author offers the hypothesis that the clinical ramifications of either disguise or consent are not exclusively, nor even necessarily, concerned with what patients read about themselves, but what they assess or intuit--directly or indirectly through the material presented--of their analyst's unconscious strivings. To truly triangulate the clinical reporting project, it is wisest to consult the third ear of a colleague to assess the potential impact on patients on what might be being unconsciously transmitted by the analyst in the writing and the consent process.

    Objective To examine the diagnostic accuracy of standard clinical tests for the shoulder in recreational athletes with activity related pain. Design Cohort study with index test of clinical examination and reference standard of arthroscopy. Setting Sports Medicine clinic in Sheffield, U.K. Participants 101 recreational athletes (82 male, 19 female; mean age 40.8 ± 14.6 years) over a six year period. Interventions Bilateral evaluation of movements of the shoulder followed by standardized shoulder tests, formulation of clinical diagnosis and shoulder arthroscopy conducted by the same surgeon. Main Outcome Measurements Sensitivity, specificity, likelihood ratio for a positive test and over-all accuracy of clinical examination was examined retrospectively and compared with arthroscopy. Results Isolated pathology was rare, most patients (72%) having more than one injury recorded. O'Brien's clinical test had a mediocre sensitivity (64%) and over-all accuracy (54%) for diagnosing SLAP lesions. Hawkins test and Jobe's test had the highest but still not impressive over-all accuracy (67%) and sensitivity (67%) for rotator cuff pathology respectively. External and internal impingement tests showed similar levels of accuracy. When a positive test was observed in one of a combination of shoulder tests used for diagnosing SLAP lesions or rotator cuff disease, sensitivity increased substantially whilst specificity decreased. Conclusions The diagnostic accuracy of isolated standard shoulder tests in recreational athletes was over-all very poor, potentially due to the majority of athletes (71%) having concomitant shoulder injuries. Most likely, this means that many of these injuries are missed in general practice and treatment is therefore delayed. Clinical examination of the shoulder should involve a combination of clinical tests in order to identify likely intra articular pathology which may warrant referral to specialist for surgery.

    Peripheral arterial disease (PAD) describes the clinical manifestations of atherosclerosis affecting the circulation in the legs. The severity of PAD is classified according to symptom severity, time course, and anatomical distribution. The signs and symptoms of PAD reflect the degree of circulatory compromise and whether there has been a gradual reduction in the circulation or an abrupt, uncompensated decrease. Accurate clinical assessment underpins decisions on management strategy and should objectively assess the severity of the ischemia and need for revascularization. Clinical history should discriminate symptoms of PAD from other conditions presenting with leg pain, elucidate cardiovascular risk factors and the effect of symptoms on the patient's quality of life. Clinical examination includes signs of general cardiovascular disease and associated conditions before assessing the circulation and viability of the limb. Palpation of peripheral pulses must be augmented by determination of the ankle brachial pressure index using hand held Doppler. A whole patient approach to management is required and must include modification of cardiovascular risk status as well as dealing with the local circulatory manifestation of PAD. PMID:25435653

    In recent months one of the most controversially discussed topics among regulatory agencies, the pharmaceutical industry, journal editors, and academia has been the sharing of patient-level clinical trial data. Several projects have been started such as the European Medicines Agency´s (EMA) “proactive publication of clinical trial data”, the BMJ open data campaign, or the AllTrials initiative. The executive director of the EMA, Dr. Guido Rasi, has recently announced that clinical trial data on patient level will be published from 2014 onwards (although it has since been delayed). The EMA draft policy on proactive access to clinical trial data was published at the end of June 2013 and open for public consultation until the end of September 2013. These initiatives will change the landscape of drug development and publication of medical research. They provide unprecedented opportunities for research and research synthesis, but pose new challenges for regulatory authorities, sponsors, scientific journals, and the public. Besides these general aspects, data sharing also entails intricate biostatistical questions such as problems of multiplicity. An important issue in this respect is the interpretation of multiple statistical analyses, both prospective and retrospective. Expertise in biostatistics is needed to assess the interpretation of such multiple analyses, for example, in the context of regulatory decision-making by optimizing procedural guidance and sophisticated analysis methods.

    PURPOSE Evidence suggests that patient-reported outcomes (PROs) from randomized trials in oncology may not influence clinical decision making and patient choice. Reasons for this are currently unclear and little is known about patients' interpretation of PROs. This study assessed patients' understanding of multidimensional PROs in a graphical format. PATIENTS AND METHODS Semistructured interviews in which patients interpreted a series of graphs depicting simple, then multiple different hypothetical PROs associated with two treatments with identical chances of survival were audio recorded. The interviewer and a blinded observer (listening to audio recordings) scored patients' understanding of the graphs. Logistic regression examined the associations between patient understanding of the graphs and clinical and sociodemographic details. Results One hundred thirty-two patients with esophageal and gastric cancer were interviewed and 115 understood the first two graphs depicting different PROs of two treatments (87%; 95% CI,81 to 93). Simultaneous interpretation of adverse and beneficial treatment effects was achieved by 74 (66%; 95% CI, 57 to 75). Graphs showing complex, longitudinal data were correctly interpreted by 97 (73%; 95% CI, 66 to 81) and 108 (81%; 95% CI, 75 to 88), respectively. Univariable analyses demonstrated associations between patient understanding and patient age, educational level, and cancer site (P < or = .02 for all); however, in a multivariable model each of these associations was attenuated. CONCLUSION Most patients understand graphical multidimensional PROs, although a smaller majority were able to interpret more complex, or simultaneous, presentations. Additional work is needed to define methods for communicating clinical and PRO data from trials to allow patients to make informed treatment choices. PMID:20065187

    Claudins are the most important structural and functional components of tight-junction integral membrane proteins. They play roles in major cellular functions including growth and adhesion and are responsible for regulating the paracellular transport of molecules. The objective of this study was to determine the clinical significance of the serum levels of claudin-1, an oldest and important member of the claudin family, in melanoma patients. A total of 98 patients with a pathologically confirmed melanoma were enrolled into this study. Serum claudin-1 concentrations were determined by the solid-phase sandwich enzyme-linked immunosorbent assay method. Age-matched and sex-matched 43 healthy controls were included in the analysis. The median age at diagnosis was 51 years, ranging from 16 to 85 years. The majority of the patients were male (61%) and had axial localized (54%) and metastatic disease (61%). Moreover, most of the patients with metastatic disease had M1c (73%). The baseline serum claudin-1 levels of the melanoma patients were significantly lower than those of control subjects (median values 9.17 vs. 13.82 ng/ml, respectively, P<0.001). However, known clinical variables including age of the patient, sex, site of lesion, histology, lymph node involvement, stage of disease, serum lactate dehydrogenase levels, and response to chemotherapy were not found to be correlated with serum claudin-1 concentrations (P>0.05). Similarly, serum claudin-1 concentration was found to have no prognostic role in survival (P=0.524). In conclusion, serum levels of claudin-1 may have a diagnostic value in melanoma patients. However, its predictive and prognostic value has not been determined. PMID:26886788

    A strong relationship between patient data and preoperative clinical decisions could potentially be used to support clinical decisions in preoperative management. The aim of this exploratory study was to determine the relationship between key patient data and pooled clinical opinions on management. In a previous study, panels of anaesthetists compared the quality of computer-assisted patient health assessments with outpatient consultations and made decisions on the need for preoperative tests, no preoperative outpatient assessment, possible postoperative intensive care unit/high dependency unit requirements and aspiration prophylaxis. In the current study, the relationship between patient data and these decisions was examined using binomial logistic regression analysis. Backward stepwise regression was used to identify independent predictors of each decision (at P >0.15), which were then incorporated into a predictive model. The number of factors related to each decision varied: blood picture (four factors), biochemistry (six factors), coagulation studies (three factors), electrocardiography (eight factors), chest X-ray (seven factors), preoperative outpatient assessment (17 factors), intensive care unit requirement (eight factors) and aspiration prophylaxis (one factor). The factor types also varied, but included surgical complexity, age, gender, number of medications or comorbidities, body mass index, hypertension, central nervous system condition, heart disease, sleep apnoea, smoking, persistent pain and stroke. Models based on these relationships usually demonstrated good sensitivity and specificity, with receiver operating characteristics in the following areas under curve: blood picture (0.75), biochemistry (0.86), coagulation studies (0.71), electrocardiography (0.90), chest X-ray (0.85), outpatient assessment (0.85), postoperative intensive care unit requirement (0.88) and aspiration prophylaxis (0.85).

    This work was aimed to study clinical features of H. pylori-associated duodenal ulcer (DU) and elucidate morphological features of gastric mucosa (GM) in patients with bronchial asthma (BA). Simultaneous prospective examination of 118 patients aged 18-64 yr included clinical and endoscopic study of the gastroduodenal region with the assessment of gastroenterological symptoms and morphological analysis of GM and duodenal biopsies by histological, histochemical, and morphometric methods. It was shown that GM inflammation in patients with DU and BA is associated not only with H. pylori infection but also with the phase of BA. Structural changes of GM in the patients with DU and BA, unlike those with DU without BA, were apparent not only in the antrum but also in the fundus. Growing density of eosinophil, neutrophil and mast cell infiltration of fundal and antral GM as well as increased total number of cells in the antrum reflects active immune-mediated inflammation in GM lamina propria. It is concluded that negative effect of uncontrolled BA on the clinical course of DU is not restricted to the association of DU exacerbation with the absence of BA control; it is also responsible for enhanced activity of gastritis. One of the possible factors determining combination of H. pylori-associated duodenal ulcer with BA is chronic hyperergic inflammation and marked structural changes in GM. PMID:25269182

    The clinical characteristics of 16 patients with congenital anosmia were examined retrospectively. MRI (magnetic resonance imaging) was used to assess the morphological changes in the olfactory bulbs and olfactory sulci according to the method of P. Rombaux (2009). Congenital anosmia was divided into two forms: syndromic forms in association with a syndrome, and isolated forms without evidence of other defects. Only three patients (19%) in our series had syndromic forms of congenital anosmia, such as the Kallmann syndrome. Most cases (13 patients, 81%) had isolated congenital anosmia. Psychophysical testing of the olfactory function included T&T olfactometry and the intravenous Alinamin test, which are widely used in Japan. In T&T olfactometry, detection and recognition thresholds for the five odorants are used to assign a diagnostic category representing the level of olfactory function. Most cases (14 patients, 88%) showed off-scale results on T&T olfactometry, and the Alinamin test resulted in no response in all 11 patients who underwent the test. Abnormal MRI findings of the olfactory bulbs and sulci were detected in 15 of 16 patients (94%). Olfactory bulbs were bilaterally absent in nine patients (56%), and two patients (13%) had unilateral olfactory bulbs. Four patients (25%) had bilateral hypoplastic olfactory bulbs, and only one patient had normal olfactory bulbs (6%). The olfactory sulcus was unilaterally absent in one patient (6%), and nine patients (56%) had bilaterally hypoplastic olfactory sulci. Two patients (13%) had a unilateral normal olfactory sulcus and hypoplastic olfactory sulcus. Three patients (19%) had normal olfactory sulci. Quantitative analysis showed that the volume of olfactory bulbs varied from 0 mm3 to 63.5 mm3, with a mean volume of 10.20 ± 18 mm3, and the mean depth of the olfactory sulcus varied from 0 mm to 12.22 mm, with a mean length of 4.85 ± 4.1 mm. Currently, there is no effective treatment for congenital anosmia. However

    Sensorineural hearing loss is one of the most common neurosensory disorders in humans. The incidence of SNHL is estimated to be 1 in 500-1000 newborns. In more than half of these patients, the hearing loss is associated with genetic causes. In Japan, genetic testing for the patients with SNHL using the Invader assay to screen for 46 mutations in 13 deafness genes was approved by the Ministry of Health, Labour and Welfare for inclusion in social health insurance coverage in 2012. Furthermore, from August 2015, this genetic testing has been expanded to screen for 154 mutations in 19 deafness genes using targeted genomic enrichment with massively parallel DNA sequencing combined with the Invader assay and TaqMan genotyping. For this study we analyzed 717 unrelated Japanese hearing loss patients. The total allele frequency of 154 mutations in 19 deafness genes was 32.64% (468/1434) and the total numbers of cases associated with at least one mutation was 44.07% (316/717). Among these, we were able to diagnose 212 (30%) patients, indicating that the present screening could efficiently identify causative mutations in hearing loss patients. It is noteworthy that 27 patients (3.8%) had coexistent multiple mutations in different genes. Five of these 27 patients (0.7%, 5/717 overall) were diagnosed with genetic hearing loss affected by concomitant with responsible mutations in more than two different genes. For patients identified with multiple mutations in different genes, it is necessary to consider that several genes might have an impact on their phenotypes. PMID:27627659

    Tofacitinib is an oral Janus kinase inhibitor that is being investigated for psoriasis and psoriatic arthritis. Japanese patients aged 20 years or more with moderate to severe plaque psoriasis and/or psoriatic arthritis were double-blindly randomized 1:1 to tofacitinib 5 or 10 mg b.i.d. for 16 weeks, open-label 10 mg b.i.d. for 4 weeks, then variable 5 or 10 mg b.i.d. to Week 52. Primary end-points at Week 16 were the proportion of patients achieving at least a 75% reduction in Psoriasis Area and Severity Index (PASI75) and Physician's Global Assessment of "clear" or "almost clear" (PGA response) for psoriasis, and 20% or more improvement in American College of Rheumatology criteria (ACR20) for patients with psoriatic arthritis. Safety was assessed throughout. Eighty-seven patients met eligibility criteria for moderate to severe plaque psoriasis (5 mg b.i.d., n = 43; 10 mg b.i.d., n = 44), 12 met eligibility criteria for psoriatic arthritis (5 mg b.i.d., n = 4; 10 mg b.i.d., n = 8) including five who met both criteria (10 mg b.i.d.). At Week 16, 62.8% and 72.7% of patients achieved PASI75 with tofacitinib 5 and 10 mg b.i.d., respectively; 67.4% and 68.2% achieved PGA responses; all patients with psoriatic arthritis achieved ACR20. Responses were maintained through Week 52. Adverse events occurred in 83% of patients through Week 52, including four (4.3%) serious adverse events and three (3.2%) serious infections (all herpes zoster). No malignancies, cardiovascular events or deaths occurred. Tofacitinib (both doses) demonstrated efficacy in patients with moderate to severe plaque psoriasis and/or psoriatic arthritis through 52 weeks; safety findings were generally consistent with prior studies.

    Information is given a privileged place in the psychiatric clinic, as illustrated by the prevalence and volume of data to be collected and forms to be completed by psychiatric nurses. Information though is different to knowledge. The present paper argues that information is part of a managerial discourse that implies commodification whereas knowledge is part of a clinical discourse that allows room for the suffering of the patient. Information belongs to the discourse of managerialism, one that positions the patient as customer/consumer and in doing so renders them unsuffering. The patient's suffering is silenced by their construction as a consumer. The discourse of managerialism seeks a complete data set of information. By way of contrast, another discourse, that of psychoanalysis offers the institution the idea that there are always holes, gaps, and uncertainty. The idea of uncertainty, gaps, things remaining unknown and a limit sits uncomfortably with the dominant discourse of managerialism; one that demands no limits, complete data sets, and many satisfied customers. This market model of managerialism denies the potential of the therapeutic relationship; that something curative might be produced via the transference. In addition, the managerialist discourse potentially positions the patient as both illegitimate and unsuffering. PMID:16296997

    The immunogenicity and safety of an inactivated cell culture Japanese encephalitis vaccine (CC-JEV) were compared with those of an inactivated mouse brain-derived Japanese encephalitis vaccine (MB-JEV) in phase III clinical multicenter trials conducted in children. The vaccines contain the same Japanese encephalitis virus strain, the Beijing-1 strain. Two independent clinical trials (trials 1 and 2) were conducted. Trial 1 was conducted in 468 healthy children. Each subject was injected with 17 μg per dose of either CC-JEV or MB-JEV, and the immunogenicity and safety of the vaccines were investigated. Trial 1 showed that CC-JEV was more immunogenic and reactive than MB-JEV at the same dose. Therefore, to adjust the immunogenicity of CC-JEV to that of MB-JEV, a vaccine that has had a good track record regarding its efficacy for a long time, trial 2 was conducted in 484 healthy children. To improve the stability, CC-JEV was converted from a liquid type to a freeze-dried type of vaccine. Each subject was injected subcutaneously with either 4 μg per dose of CC-JEV, 8 μg per dose of CC-JEV, or 17 μg per dose of MB-JEV twice, at an interval of 2 to 4 weeks, followed by an additional booster immunization 1 to 15 months after the primary immunization. Based on the results of trial 2, 4 μg per dose of the freeze-dried CC-JEV (under the label Encevac) was selected as a substitute for the MB-JEV. Encevac was approved and launched in 2011 and has since been in use as a 2nd-generation Japanese encephalitis vaccine in Japan. (These studies have been registered at the JapicCTI under registration no. JapicCTI-132063 and JapicCTI-080586 for trials 1 and 2, respectively.) PMID:24334689

    Common variable immunodeficiency (CVID) is characterized by an impaired antibody production and an increased susceptibility to recurrent infections of the respiratory tract, mainly by extracellular encapsulated bacteria. We analyzed the clinical characteristics of 69 patients evaluated over a period of 10 years at three centers in the city of Buenos Aires. At the onset of the study 14 patients were on follow up, and at its end the number of patients reached to 60. Most of them consulted for infection or hypogammaglobulinemia and nearly half had an established diagnosis of immunodeficiency. Sixty-five (94.2%) patients had infections by encapsulated bacteria, four (6.1%) sepsis and two tuberculosis. The average age of onset of infectious symptoms was 18.1 years; the average age at diagnosis was 29.6 years and the delay to diagnosis 11.9 years. Forty one (59.4%) patients reported a history of recurrent or chronic diarrhea. In 22 (31.9%) 13 autoimmune diseases were diagnosed, being the most frequent the hematological disorders and hypothyroidism. Eight patients had histological polyclonal lymphoproliferation, four (5.8%) with granulomatous disease affecting the liver, the larynx and/or the skin; and four as lymphoid interstitial pneumonitis (LIP). Nineteen (27.5%) patients had splenomegaly and 23/57 (40.3%) images suggestive of lymphocytic or granulomatous processes (including the 4 with LIP) in the chest CT. Three (4.3%) patients developed B cell lymphoma, four (5.8%) stomach adenocarcinoma and one breast cancer. The study had a median follow-up of 54 months, range 1-353 and four patients (5.8%) died during the follow up. PMID:23924529

    The diagnosis of non-cirrhotic portal hypertension (NCPH), a rare but potentially life-threatening complication in human immunodeficiency virus (HIV)-positive individuals, often occurs only after the emergence of fatal manifestations such as bleeding of esophageal varices. We herein report a female Japanese HIV patient who developed NCPH approximately 4 years after discontinuation of 65 months of didanosine (ddI) administration. The patient presented with severe ascites, bloody bowel discharge, extreme abdominal swelling, and symptoms of portal hypertension but no sign of liver cirrhosis. Examination revealed esophageal varices, oozing-like bleeding from a wide part of the colon, significant atrophy of the right lobe of the liver, and arterio-portal shunting and recanalization from the left medial segment branch of the portal vein to a paraumbilical vein, but no visible obstruction of the main trunk of the portal vein. Treatment for esophageal varices consisted of coagulation therapy with argon plasma after enforcement by endoscopic sclerotherapy and oral administration of β-blockers for elevated portal blood pressure. The patient has not experienced gastrointestinal bleeding in the approximately 5 years since the diagnosis of NCPH. Reviewing this case suggests the importance of suspecting NCPH in HIV patients with liver dysfunction of unknown etiology with a history of ddI and other purine analogs use, as well as the importance of controlling portal hypertension and esophageal varices in the treatment of NCPH.
