    The pathophysiological backgrounds as well as clinical phenotypes of Japanese or East Asian patients with type 2 diabetes are quite different from those in Western countries. According to results of East Asian large-scale studies such as the Japan Diabetes Complications Study (JDCS), which is a representative cohort of Japanese patients with type 2 diabetes, Japanese patients had a much lower body mass index and lower incidence of coronary heart disease compared with Caucasian diabetic patients. Other differences between Japanese and Caucasian patients with type 2 diabetes could be found in risk factors such as fruit intake on retinopathy and significance of triglycerides, or the effects of moderate alcohol drinking on cardiovascular disease. These results demonstrated a necessity of ethnic group-specific risk evaluations and care of type 2 diabetes and its complications.

    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

    We report the clinical outcome and prognostic factors in 39 cases of childhood Japanese Encephalitis admitted to a tertiary hospital of Upper Assam and followed up for 421 days in the community. The mortality rate was 20.5% in our study. The mean GCS (9.97 +/- 0.91) was higher in surviving cases than the fatal cases (GCS 7.5 +/- 1.78) at admission. The fatal cases died within 4.75 +/- 3.19 days in the hospital. All the patients had low BMI (surviving cases 13.54 +/- 2.3; fatal cases 12.05 +/- 0.12) and were anemic. Cerebrospinal fluid (CSF) was clear in 91.4% cases but pressure and protein content were increased in all cases. About 10% cases had parkinsonian features at the time of discharge. Residual symptoms remained in about one third of cases even after 421 days. PMID:12522277

    Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious and hemorrhagic disease recently described in China and western Japan. A 71-year-old healthy Japanese woman noticed a tick biting her after harvesting in an orchard and removed it herself. She developed diarrhea, anorexia, and chills eight days later. Because these symptoms continued, she visited a primary care physician 6 days after the onset. Laboratory data revealed thrombocytopenia, leukocytopenia, and elevated liver enzymes. She was then referred to our hospital. Although not completely fulfilling the diagnostic criteria used in a retrospective study in Japan, SFTS was suspected, and we detected SFTS virus in the patient's blood using RT-PCR. However, she recovered without intensive treatment and severe complications 13 days after the onset. In this report, we present a mild clinical course of SFTS virus infection in Japan in detail.

    The DuraHeart ventricular assist device (VAD) is a third-generation implantable centrifugal pump with a magnetically levitated impeller. Since February 2007, the device has been clinically applied with excellent results as a bridge to heart transplantation in Europe. As of this writing, however, the device has yet to be approved by the Ministry of Health, Labour and Welfare for clinical use in Japan. We herein report the first clinical application of this device for a Japanese patient. A 31-year-old man with dilated cardiomyopathy was transferred to the Heart and Diabetes Center NRW (HDZ-NRW) in Bad Oeynhausen, Germany, where he was to await heart transplantation. The transfer was safely completed under management with low-dose dopamine. His condition gradually deteriorated at HDZ-NRW, and the DuraHeart left ventricular assist device was implanted for the left ventricle at 7 weeks after admission. Shortly thereafter, however, on POD 7, a Thoratec VAD had to be inserted on the right side due to refractory right heart failure. The right ventricular assist device could be explanted after a 3-month assist, and the patient is now waiting for heart transplantation at home in Germany.

    Conventional synthetic disease-modifying anti-rheumatic drugs, including methotrexate, may not be tolerated by all patients with rheumatoid arthritis (RA), and limited international data for etanercept (ETN) monotherapy are available. The aim of this review was to summarize the clinical program for ETN monotherapy in Japanese patients with RA, which has included a pharmacokinetic study, clinical trials for registration, long-term studies, and once-weekly dosing studies. Pharmacokinetic results showed that serum concentrations of ETN were linear with dose levels and were similar to other international studies. Across interventional studies, 652 Japanese patients with active RA were treated with ETN. In the registration studies, ETN treatment led to consistent improvement in American College of Rheumatology 20/50/70 scores, European League Against Rheumatism Good Response, Disease Activity Score 28 erythrocyte sedimentation rate remission, and Health Assessment Questionnaire disability index. In the long-term studies, efficacy was maintained for up to 180 weeks. Similar results were seen in the once-weekly studies. Across the studies, more than 870 patient-years of exposure to ETN were recorded. Discontinuations owing to lack of efficacy or adverse events were modest and no new safety signals were recorded. These studies demonstrated that ETN monotherapy is efficacious and well-tolerated in Japanese patients with RA. PMID:24842477

    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.

    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

    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

    Abstract Background: This study was conducted to evaluate the safety and tolerability, and population pharmacokinetics (PPK) of montelukast as well as efficacy in the treatment of perennial allergic rhinitis (PAR) in paediatric Japanese patients aged between 1 and 15 years. Methods: In this multi-centre, open-label trial, 87 paediatric Japanese patients with PAR received montelukast 4 mg oral granules (OG) for 4 weeks (1–5-year-olds, N = 15), 4 mg OG for 12 weeks (1–5-year-olds, N = 36), 5 mg chewable tablets (CT) for 12 weeks (6–9-year-olds, N = 18), or 5 mg CT for12 weeks (10–15-year-olds, N = 18). Clinical exams and laboratory assessments were conducted at study visits, and adverse events (AE) were monitored throughout the study up to 14 days after the last visit. Population pharmacokinetic approach was used to estimate AUC0–∞, Cmax, Tmax and apparent elimination half-life in each age group. Efficacy was assessed based on global evaluations by the subject’s caregiver. Results: There were no serious AEs and one discontinuation due to an AE. The most common AEs in any of the treatment groups were nasopharyngitis, pharyngitis, and acute sinusitis. Montelukast exposure (AUC0–∞) was similar in the 1–5-year-old group and the 6–9-year-old group, but 19% lower in the 10–15-year-old group. Among all patients, the total proportion of patients whose global evaluation was “very much better” was 5.7% (week 2), 11.5% (week 4), and 16.9% (week 12) reflecting improvement in symptoms over time. Conclusion: Montelukast was generally well tolerated in Japanese children with PAR. AUC0–∞was similar in 1–5 and 6–9-year-olds, while a lower exposure was observed in the 10–15-year-old group likely due to differences in bodyweight. The exposure in Japanese paediatric patients was generally consistent with that in non-Japanese paediatric and adult patients. As assessed by the patients’ caregivers, montelukast also

    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.

    Guillain-Barré syndrome (GBS) is the commonest cause of flaccid paralysis worldwide. Miller Fisher syndrome (MFS) is a variant of GBS characterized by ophthalmoplegia and ataxia. Together GBS and MFS form a continuum of discrete and overlapping subtypes, the frequency of which remains unknown. We retrospectively analysed the clinical features (antecedent symptoms, pattern of neurological weakness or ataxia, presence of hypersomnolence) of 103 patients at a single hospital in Japan. Patients were then classified according to new diagnostic criteria (Wakerley et al., 2014). Laboratory data (neurophysiology and anti-ganglioside antibody profiles) were also analysed. According to the new diagnostic criteria, the 103 patients could be classified as follows: classic GBS 73 (71%), pharyngeal-cervical-brachial weakness 2 (2%), acute pharyngeal weakness 0 (0%), paraparetic GBS 1 (1%), bifacial weakness with paraesthesias 1 (1%), polyneuritis cranialis 0 (0%), classic MFS 18 (17%), acute ophthalmoparesis 1 (1%), acute ptosis 0 (0%), acute mydriasis 0 (0%), acute ataxic neuropathy 1 (1%), Bickerstaff brainstem encephalitis 3 (3%), acute ataxic hypersomnolence 0 (0%), GBS and MFS overlap 1 (1%), GBS and Bickerstaff brainstem encephalitis overlap 1 (1%), MFS and pharyngeal-cervical-brachial weakness overlap 1 (1%). Application of the new clinical diagnostic criteria allowed accurate retrospective diagnosis and classification of GBS and MFS subtypes. PMID:27653863

    Objective To investigate the association between knee pain during gait and 4 clinical phenotypes based on static varus alignment and varus thrust in patients with medial knee osteoarthritis (OA). Methods Patients in an orthopedic clinic (n = 266) diagnosed as having knee OA (Kellgren/Lawrence [K/L] grade ≥1) were divided into 4 phenotype groups according to the presence or absence of static varus alignment and varus thrust (dynamic varus): no varus (n = 173), dynamic varus (n = 17), static varus (n = 50), and static varus + dynamic varus (n = 26). The knee range of motion, spatiotemporal gait parameters, visual analog scale scores for knee pain, and scores on the Japanese Knee Osteoarthritis Measure were used to assess clinical outcomes. Multiple logistic regression analyses identified the relationship between knee pain during gait and the 4 phenotypes, adjusted for possible risk factors, including age, sex, body mass index, K/L grade, and gait velocity. Results Multiple logistic regression analysis showed that varus thrust without varus alignment was associated with knee pain during gait (odds ratio [OR] 3.30, 95% confidence interval [95% CI] 1.08–12.4), and that varus thrust combined with varus alignment was strongly associated with knee pain during gait (OR 17.1, 95% CI 3.19–320.0). Sensitivity analyses applying alternative cutoff values for defining static varus alignment showed comparable results. Conclusion Varus thrust with or without static varus alignment was associated with the occurrence of knee pain during gait. Tailored interventions based on individual malalignment phenotypes may improve clinical outcomes in patients with knee OA. PMID:26017348

    BACKGROUND Because the efficacy and safety of pazopanib in Japanese patients with soft tissue sarcoma (STS) had not been evaluated previously in a large‐scale cohort, the authors investigated the efficacy and safety of pazopanib in 156 Japanese patients with relapsed STS. This was a retrospective study based on the collection of real‐life, postmarketing surveillance data. METHODS Patients received pazopanib with the objective of treating local recurrence (n = 20), metastasis (n = 104), and both (n = 32). The patient median age was 53.8 years. The primary objective of this study was to clarify the efficacy of pazopanib for patients with STS. RESULTS The median treatment duration was 28.7 weeks, and the average dose intensity of pazopanib was 609 mg. Adverse events occurred in 127 patients (81.4%). In addition to the main common toxicities, such as hypertension and liver disorder, pneumothorax (n = 11) and thrombocytopenia (n = 16) also were observed. The median progression‐free survival for all patients was 15.4 weeks. The median progression‐free survival for patients with leiomyosarcoma, synovial sarcoma, undifferentiated pleomorphic sarcoma, and liposarcoma was 18.6 weeks, 16.4 weeks, 15.3 weeks, and 8 weeks, respectively. The median survival for all patients was 11.2 months. The median survival for patients with leiomyosarcoma, synovial sarcoma, undifferentiated pleomorphic sarcoma, and liposarcoma was 20.1 months, 10.6 months, 9.5 months, and 7.3 months, respectively. CONCLUSIONS There were apparent differences in the efficacy of pazopanib treatment among histologic types of STS. Pazopanib treatment is a new treatment option; however, adverse events like pneumothorax and thrombocytopenia, which did not occur frequently in the PALETTE study (pazopanib for metastatic soft‐tissue sarcoma), should be taken into consideration.

    Objective In Japan, there had been no prospective clinical studies conducted in terms of modified FOLFOX6 + bevacizumab therapy. We performed a post-marketing Phase II multicenter clinical study to examine the efficacy and safety of this regimen as first-line therapy for Japanese patients with advanced/recurrent colorectal cancer. Methods Bevacizumab (5 mg/kg) was administered intravenously, and then oxaliplatin (85 mg/m2) and levofolinate calcium (200 mg/m2) were infused intravenously over 2 h. Subsequently, a bolus dose of 5-fluorouracil (400 mg/m2) was injected, followed by infusion of 5-fluorouracil (2400 mg/m2) for 46 h. This regimen was repeated every 2 weeks until 24 cycles unless there was disease progression, unacceptable toxicity or patient refusal. The primary end point was the response rate. Results Among the 70 patients enrolled, two patients withdrew the study before treatment, and 68 patients were eligible for analysis of efficacy and safety. The response rate was 51.5% (95% confidence interval: 39.0–63.8%). The median progression-free survival and median overall survival time were 12.6 months (95% confidence interval: 10.4–14.5 months) and 28.5 months [95% confidence interval: 23.1 months–(not applicable)], respectively. There were no treatment-related deaths observed. The most common Grade 3 and 4 adverse events included neutropenia in 35.3% of the patients, peripheral neuropathy in 16.2% and hypertension in 16.2%. All adverse events were manageable and tolerable. The exploratory analysis of polymorphisms of three genes, ERCC1, XPD and GSTP1, did not show any trends in terms of correlation with the efficacy or safety of modified FOLFOX6 + bevacizumab therapy. Conclusions Modified FOLFOX6 + bevacizumab therapy was manageable and tolerable in Japanese patients, achieving a high response rate. PMID:23999770

    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.

    Carboplatin is a platinum-based anticancer drug that has been long used to treat many types of solid cancer. Because the clearance of carboplatin strongly correlates with the glomerular filtration rate (GFR), its dosage is calculated with the Calvert formula on the basis of the patient's GFR to achieve the target area under the plasma drug concentration-time curve (AUC) for each patient. However, many lines of evidence from previous clinical studies should be interpreted with caution because different methods were used to estimate drug clearance and derive the dosage of carboplatin. There is a particularly high risk of carboplatin overdosing when the dosage is determined on the basis of standardized serum creatinine values. When deciding the dose of carboplatin for adult Japanese patients, preferred methods to assess renal function instead of directly measuring GFR include (1) 24-h urinary collection-based creatinine clearance adjusted by adding 0.2 mg/dl to the serum creatinine concentration measured by standardized methods, and (2) equation-based GFR (eGFR) with a back calculation to units of ml/min per subject. Given the limitations of serum creatinine-based GFR estimations, the GFR or creatinine clearance should be directly measured in each patient whenever possible. To ensure patient safety and facilitate a medical-team approach, the single most appropriate method available at each institute or medical team should be consistently used to calculate the dose of carboplatin with the Calvert formula.

    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

  1. Children who survived Japanese concentration camps: clinical observations and therapy.

    The majority of children who survived concentration camps have remained silent about their experiences. Their memories, rather than fading with time, have intensified. In the 1970s previously silent Jewish child survivors declared themselves through books and films. Child survivors of Dutch origin who were the victims of Japanese concentration camps are similarly emerging from silence. Parents and even psychiatrists do not credit child survivors with their ability to remember. As a result, child survivors have difficulty verifying their memories and have spoken very little about them. The numbers of patients with this particular childhood experience are increasing as noted in Dutch clinics devoted to the care of victims of war. This paper focuses on two such patients in order to alert North American psychiatrists to their existence and to crucial aspects of their care.

    The purpose of this article is to disseminate the standard of antiemetic therapy for Japanese clinical oncologists. On the basis of the Appraisal of Guidelines for Research and Evaluation II instrument, which reflects evidence-based clinical practice guidelines, a working group of the Japanese Society of Clinical Oncology (JSCO) reviewed clinical practice guidelines for antiemesis and performed a systematic review of evidence-based domestic practice guidelines for antiemetic therapy in Japan. In addition, because health-insurance systems in Japan are different from those in other countries, a consensus was reached regarding standard treatments for chemotherapy that induce nausea and vomiting. Current evidence was collected by use of MEDLINE, from materials from meetings of the American Society of Clinical Oncology National Comprehensive Cancer Network, and from European Society of Medical Oncology/Multinational Association of Supportive Care in Cancer guidelines for antiemesis. Initially, 21 clinical questions (CQ) were selected on the basis of CQs from other guidelines. Patients treated with highly emetic agents should receive a serotonin (5-hydroxytryptamine; 5HT3) receptor antagonist, dexamethasone, and a neurokinin 1 receptor antagonist. For patients with moderate emetic risk, 5HT3 receptor antagonists and dexamethasone were recommended, whereas for those receiving chemotherapy with low emetic risk dexamethasone only is recommended. Patients receiving high-emetic-risk radiation therapy should also receive a 5HT3 receptor antagonist. In this paper the 2010 JSCO clinical practice guidelines for antiemesis are presented in English; they reveal high concordance of Japanese medical circumstances with other antiemetic guidelines that are similarly based on evidence.

    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.

    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 the summer of 1982, we experienced a great number of patients with Japanese encephalitis compared with the previous years. We have studied 85 adult cases of Japanese encephalitis which were diagnosed clinically and/or serologically. A difference between improved and expired cases was also investigated. We found that deteriorated mental state, elevated SGOT (AST) level, lower hemagglutination-inhibition(H-I) titer, and a more acute onset of the illness were associated with higher mortality. The mortality rate in our cases was 35.3 percent. PMID:15759371

    Anti-HER2 agents, such as trastuzumab, lapatinib, trastuzumab emtansine (T-DM1), and pertuzumab, are standard agents in the treatment of breast cancer overexpressing the human epidermal growth factor receptor 2 (HER2). Trastuzumab is the first approved HER2-targeted agent. Subsequent developments include agents with different mechanisms. In this paper, we review the results of clinical trials of T-DM1, a new anti-HER2 agent, with a focus on Japanese patients with breast cancer. On the basis of results from a Phase I study (JO22591), the maximum tolerated dose was determined to be 3.6 mg/kg every 3 weeks for both Japanese and western patients. In a Phase II study (JO22997), the overall response rate was 38.4% (90% confidence interval 28.8–48.6). T-DM1 was well tolerated in Japanese patients; however, the incidence of grade 3 or 4 thrombocytopenia was higher than that observed in earlier western studies, but was not associated with clinically important symptoms. Pharmacokinetic parameters for T-DM1 and its metabolites were consistent with those reported previously from a Phase I or II study in non-Japanese patients, and the data obtained showed no suggestion of ethnic differences. Several Phase III studies of T-DM1 are ongoing throughout the world, including in Japanese patients with breast cancer. PMID:24833915

    Cold sensation and numbness have been reported as post-stroke sensory sequelae attributable to distal axonopathy, which is caused by chronic ischemia of diseased limbs resulting from dysfunction of vasomotor regulatory systems. Keishibukuryogan is a traditional herbal medicine used to treat symptoms of peripheral ischemia such as cold extremities. This study investigated clinical improvement and skin temperature in peripheral ischemia patients to determine the efficacy of keishibukuryogan in alleviating post-stroke cold sensation and numbness. Twenty-two stroke patients with cold sensation and/or numbness were enrolled in this study. Subjective cold sensation and numbness, evaluated using the visual analogue scale, were found in 21 and 31 limbs, respectively. The skin temperature of diseased and healthy limbs was recorded. We observed all patients for 4 weeks and 17 patients for 8 weeks after administration of keishibukuryogan. The skin temperature of diseased limbs was significantly higher than baseline at 4 weeks and 8 weeks, whereas that of healthy limbs did not change significantly. Cold sensation and numbness were significantly improved at 4 weeks and 8 weeks compared to baseline. Keishibukuryogan administration resulted in warming of diseased limbs and improved cold sensation and numbness, probably by increasing peripheral blood flow.

    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

    We report on a sclerosing bone dysplasia, associated with cutis laxa, enamel dysplasia, and mental retardation. The patient was a 17-year-old Japanese boy of normal height and muscular build. Cutis laxa with prominent veins in the scalp and abdominal wall and delayed eruption of permanent teeth attracted the attention of clinicians in infancy and adolescence, respectively. The clinical manifestations included a progeroid facial appearance with prognathism, wrinkled skin, and interdigital webbing. The intelligence quotient was estimated at 60. Enamel dysplasia was histologically confirmed. Skeletal changes included calvarial hyperostosis, sclerosis of the skull base, an enlarged, sclerotic mandible, broad clavicles and ribs, and diaphyseal undermodeling of the tubular bones. Metaepiphyseal sclerosis or longitudinal striation was found in the long bones. Metaphyseal equivalents of the axial skeleton showed dense osteosclerosis. These clinical and radiological manifestations overlapped with those of Lenz-Majewski syndrome. Unlike the classical phenotype of the disorder, however, he did not show brachymesophalangy with proximal symphalangism or growth failure. The present case may be considered to fall in the mildest end in the phenotypic continuum of Lenz-Majewski syndrome, suggesting that the clinical spectrum of the disorder may be broader than currently thought.

    Although Japanese cases of sporadic Creutzfeldt-Jakob disease (sCJD) generally involve longer survival periods compared to those from other countries, details regarding the factors influencing survival are unclear. To determine the influence of certain factors on survival, we retrospectively assessed 51 Japanese MM1-type sCJD patients with respect to background, clinical course, and disease management. No significant differences were found between men and women, tracheotomy and nontracheotomy patients, or patients treated in public and other types of hospitals. Although the survival period of tube-fed patients was significantly longer than that of patients who were not tube fed, survival of patients fed via a nasal tube did not differ significantly from that of gastrostomy-fed patients. The proportion of tube-fed patients was 68.6% (35/51). Disease duration was not significantly associated with age or year of onset. However, it was associated with time from onset to first recognition of myoclonus, first recognition of periodic sharp-wave complexes on electroencephalogram, and progression to the akinetic mutism state. Mechanical ventilation was not performed for any patient. Because the total disease duration increased in cases with a slowly progressive clinical course as a natural outcome, we concluded that the most crucial factor contributing to the prolonged survival of Japanese sCJD patients was tube feeding once the akinetic mutism state had been reached.

    2010-01-01

    Background Empirical support for cognitive behavioral therapy (CBT) for treating Japanese patients with major depression is lacking, therefore, a feasibility study of CBT for depression in Japanese clinical settings is urgently required. Findings A culturally adapted, 16-week manualized individual CBT program for Japanese patients with major depressive disorder was developed. A total of 27 patients with major depression were enrolled in a single-group study with the purpose of testing the feasibility of the program. Twenty six patients (96%) completed the study. The mean total score on the Beck Depression Inventory-II (BDI-II) for all patients (Intention-to-treat sample) improved from 32.6 to 11.7, with a mean change of 20.8 (95% confidence interval: 17.0 to 24.8). Within-group effect size at the endpoint assessment was 2.64 (Cohen's d). Twenty-one patients (77.7%) showed treatment response and 17 patients (63.0%) achieved remission at the end of the program. Significant improvement was observed in measurement of subjective and objective depression severity (assessed by BDI-II, Quick Inventory of Depressive Symptomatology-Self Rated, and Hamilton Depression Rating Scale), dysfunctional attitude (assessed by Dysfunctional Attitude Scale), global functioning (assessed by Global Assessment of Functioning of DSM-IV) and subjective well-being (assessed by WHO Subjective Well-being Inventory) (all p values < 0.001). Conclusions Our manualized treatment comprised of a 16-week individual CBT program for major depression appears feasible and may achieve favorable treatment outcomes among Japanese patients with major depression. Further research involving a larger sample in a randomized, controlled trial design is warranted. Trial registration UMIN-CTR UMIN000002542. PMID:20529252

    Background/Aims Inflammation is an established mortality risk factor in chronic kidney disease (CKD) patients. Although a previous report showed that uremic Caucasian patients with inflammation had signs of global DNA hypermethylation, it is still unknown whether DNA hypermethylation is linked to inflammatory markers including a marker of bacterial infections in Japanese CKD patients. Methods In 44 consecutive incident dialysis patients (26 males, mean age 59 ± 12 years) without clinical signs of infection, global DNA methylation was evaluated in peripheral blood DNA using the HpaII/MspI ratio by the luminometric methylation assay method. A lower ratio of HpaII/MspI indicates global DNA hypermethylation. Procalcitonin (PCT), a marker of inflammation due to bacterial infections, was measured using an immunochromatographic assay. Results The patients were divided into hyper- and hypomethylation groups based on the median value of the HpaII/MspI ratio 0.31 (range 0.29–0.37). Whereas patients in the hypermethylation group had higher ferritin levels [133.0 (51.5–247.3) vs. 59.5 (40.0–119.0) ng/ml; p = 0.046], there were no significant differences in age, gender, diabetes, smoking, anemia or serum albumin levels. However, the HpaII/MspI ratio showed significant negative correlations with PCT (ρ = −0.32, p = 0.035) and ferritin (ρ = −0.33, p = 0.027) in Spearman's rank test. In a multiple linear regression analysis, PCT and ferritin were associated with a lower HpaII/MspI ratio (R2 = 0.24, p = 0.013). Conclusion In this study, global DNA hypermethylation was associated with ferritin and, most likely, PCT, suggesting that inflammation induced by subclinical bacterial infection promoted DNA methylation.

    Toll-like receptor 3 (TLR3) may be associated with T helper 1 immune response. This study aimed to investigate the role of a functional TLR3 single nucleotide polymorphism (SNP) in sarcoidosis. We genotyped 220 Japanese patients with sarcoidosis and 140 controls for TLR3 SNP rs3775291 to analyze its association with susceptibility to sarcoidosis and assessed its relationship to clinical features in 172 patients over 2 years. The TLR3 rs3775291 genotype was not significantly associated with disease susceptibility. However, patients with cardiac sarcoidosis (CS) significantly more frequently had the TT genotype (p < 0.01) or the T allele (p < 0.05) than those patients without CS. We conclude that TLR3 SNP rs3775291 may affect cardiac involvement in Japanese patients with sarcoidosis.

    The diagnosis of sarcoidosis, a multisystem granulomatous disease of unknown etiology, is established when clinicoradiological findings are supported by histological evidence of non-caseating epithelioid cell granulomas. For pathological diagnosis, an endobronchial biopsy of normal-appearing bronchial mucosa in combination with transbronchial lung biopsy (TBLB) has been reported to be useful for sarcoidosis patients in Europe or the U.S. This is the first report assessing the utility of endobronchial biopsy for diagnosis of Japanese patients with sarcoidosis. Eighteen consecutive patients with strongly suspected sarcoidosis were evaluated by endobronchial biopsy of normal-appearing bronchial mucosa, together with TBLB and bronchoalveolar lavage. The TBLB specimens demonstrated non-caseating epithelioid cell granulomas in the lungs of 11 patients (61.1%), but not any specific findings in those of other 7 patients. In contrast, endobronchial biopsy specimens confirmed a diagnosis of sarcoidosis in only one patient that required steroid therapy for deterioration of pulmonary sarcoidosis. All 18 patients of this study, including 5 patients with pathological findings obtained from extrapulmonary sites, met the pathological or clinical diagnostic criteria. In conclusion, endobronchial biopsy of normal-appearing bronchial mucosa in combination with TBLB does not improve the diagnostic capacity for detecting sarcoidosis in Japanese patients, despite earlier reports. Thus, this method is of limited usefulness as a conventional diagnostic modality for Japanese patients with suspicious sarcoidosis. The present study also suggests the racial difference in the endobronchial involvement in pulmonary sarcoidosis.

    Non-classical 21-hydroxylase deficiency (NC21-OHD) is a mild form of 21-hydroxylase deficiency lacking apparent symptoms of androgen excess at birth. Most NC21-OHD cases are diagnosed after the onset of puberty, while a substantial number of patients are not diagnosed during childhood. Previous studies have reported ethnic differences in the prevalence of NC21-OHD. To date, the clinical features of NC21-OHD in Japanese children have not been systemically reported. Thus, we performed 3 independent analyses: retrospective analyses of newborn screening in 2 major Japanese cities (Sapporo and Niigata) and a national surveillance collecting clinical information from pediatric endocrinologists throughout the country. During the last 10 years, one case of NC21-OHD was diagnosed by newborn screening in each city, resulting in incidences of 2.0 (95% confidence interval = 0.0-5.9) and 2.1 (0.0-6.2) per 1,000,000 in Sapporo and Niigata, respectively. We collected information from 85% of the 135 Councilors of Japanese Society of Pediatric Endocrinology. Fifteen NC21-OHD patients were diagnosed during childhood, resulting in the estimated prevalence of 0.58 (0.28-1.1) per 1,000,000. Eleven patients were discovered by newborn screening, 7 patients developed hyperandrogenism symptoms (2-8 years of age, median 7), and 9 patients were treated with hydrocortisone at the time of the survey. Ten out of 13 patients showed compound heterozygosity for the P30L mutation of CYP21A2. Our study suggests that the prevalence/incidence of NC21-OHD is lower than that in Western countries, and that the age for initial onset of androgen excess symptoms varies during the prepubertal period.

    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.

    Systemic sclerosis (SSc) is a systemic autoimmune disease characterized by extensive fibrosis and autoantibodies. Its clinical manifestations are diverse and include Raynaud's phenomenon, gastrointestinal dysmotility, interstitial lung disease (ILD), pulmonary hypertension, and renal crisis. Among these, ILD is the primary cause of SSc-related death. It has been considered that acute exacerbation of ILD (AE-ILD) is not common in patients with SSc; however, little is known about the prevalence of AE-ILD in Japanese patients with SSc. In this study, we aimed to clarify the prevalence, clinical characteristics, and prognosis of patients with SSc who developed AE-ILD and to identify predictive factors for AE-ILD in our Japanese cohorts. Clinical data of patients who visited our department from 1990 to 2014 and fulfilled the 2013 classification criteria for SSc were retrospectively reviewed. A total of 139 patients were enrolled. The mean age of onset was 49.1 years, and 113 (81.3%) patients were female; 116 (83.5%) had limited cutaneous involvement, and the overall 10-year survival rate was 92.0%. Among 66 (47.5%) patients with ILD, 13 (9.4%) developed AE-ILD. Patients with AE-ILD had a significantly higher incidence of overlap with polymyositis (PM) or dermatomyositis (DM) and lower prevalence of anticentromere antibodies with higher mortality rate compared with those without AE-ILD. Multivariate Cox regression analysis identified that an overlap with PM or DM was the most significant predictive factor for AE-ILD. Our study results suggest that Japanese patients with SSc, particularly patients overlapped with PM or DM, have a high risk of AE-ILD. PMID:27487743

    Background Ethnicity has a significant impact on coronary artery disease (CAD). This study investigated the long-term outcomes of Japanese patients undergoing revascularization compared with US patients belonging to multiple ethnic groups. Methods and Results We evaluated clinical outcomes, based on ethnicity, of patients included in the Coronary Revascularization Demonstrating Outcome (CREDO-Kyoto) and the Texas (US) Heart Institute Research Database (THIRDBase) registries. For the analysis, we included 8871 patients from the CREDO-Kyoto registry (median follow-up period [FU], 3.5 years; interquartile range [IQR], 2.6–4.3) and 6717 patients from the THIRDBase registry (FU, 5.2 years; IQR, 3.8–6.5) who underwent percutaneous coronary intervention or bypass surgery. Cox proportional hazard models were constructed to compare the adjusted long-term outcomes for each ethnic group. A total of 8871 Japanese, 5170 Caucasians, 648 African-Americans, 817 Hispanics, and 82 Asian-Americans were identified. When adjusted, Japanese patients had significantly better outcomes than US patients, classified by ethnicity (Caucasians: hazard ratio [HR], 1.56; 95% confidence interval [CI], 1.35–1.79; Hispanics: HR, 1.53; 95% CI, 1.22–1.93; African-Americans: HR, 2.03; 95% CI, 1.62–2.56), except for Asian-Americans (HR, 0.84; 95% CI. 0.38–1.89) who had outcomes similar to Japanese patients. Conclusion Our findings indicate better survival outcomes in re-vascularized Japanese CAD patients compared to major ethnic groups in the US, including Caucasian, Hispanic, and African-American CAD patients. The characteristics and outcomes of Japanese CAD patients were similar to those of Asian-Americans, despite the sample size limitations in the US dataset. PMID:26023784

    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

    Few studies of end-stage renal disease (ESRD) investigate genetic and environmental effects simultaneously in one racial/ethnic group. United States Renal Data System data show racial differences in primary causes of ESRD, survival rates, and causes of death. Comparing these with Japanese Society for Dialysis Therapy data, survival rates appear better for Japanese than for US patients. To explore genetic and environmental differences, we investigated incident and prevalent ESRD patient characteristics. The United States Renal Data System and Japanese Society for Dialysis Therapy databases were analyzed between 1983 and 2002 for the following patient subsets: Americans excluding Asian Americans (n=1,153,974); Asian Americans excluding Japanese Americans (n=35,983); Hawaiian and non-Hawaiian Japanese Americans by state, race, and Japanese surname (n=3932); native Japanese living in Japan (n=450,593). Japanese Americans tended to be older, male, have more diabetes and hypertension and less glomerulonephritis, and to die more often of heart failure than the other US groups. Adjusted mortality hazard ratios were 0.70 for non-Japanese Asian Americans and 0.75 for Japanese Americans vs. non-Asian Americans (1.00). Hawaiian Japanese patients tended to be older, with more diabetes and hypertension and less glomerulonephritis than the other Japanese groups; their survival rates improved after adjustment for rate of diabetes. Japanese American ESRD patients differ from Asian and non-Asian Americans, and from native Japanese, despite similar genetic make-ups. Both genetic and environmental factors may affect patient outcomes.

    Azilsartan is a novel angiotensin receptor blocker being developed for hypertension treatment. This 16-week, multicenter, randomized, double-blind study compared the efficacy and safety of azilsartan (20–40 mg once daily by forced titration) and its ability to provide 24-h blood pressure (BP) control, with that of candesartan cilexetil (candesartan; 8–12 mg once daily by forced titration) in 622 Japanese patients with grade I–II essential hypertension. Efficacy was evaluated by clinic-measured sitting BP, and by ambulatory BP monitoring (ABPM) at week 14. Participants (mean age: 57 years, 61% males) had a mean baseline sitting BP of 159.8/100.4 mm Hg. The mean change from baseline in sitting diastolic BP at week 16 (primary endpoint) was −12.4 mm Hg in the azilsartan group and −9.8 mm Hg in the candesartan group, demonstrating a statistically significant greater reduction with azilsartan vs. candesartan (difference: −2.6 mm Hg, 95% confidence interval (CI): −4.08 to −1.22 mm Hg, P=0.0003). The week 16 (secondary endpoint) mean change from baseline in sitting systolic BP was −21.8 mm Hg and −17.5 mm Hg, respectively, a significant decrease with azilsartan vs. candesartan (difference: −4.4 mm Hg, 95% CI: −6.53 to −2.20 mm Hg, P<0.0001). On ABPM, the week 14 mean changes from baseline in diastolic and systolic BP were also significantly greater with azilsartan over a 24-h period, and during the daytime, night-time and early morning. Safety and tolerability were similar among the two groups. These data demonstrate that once-daily azilsartan provides a more potent 24-h sustained antihypertensive effect than that of candesartan but with equivalent safety. PMID:22278628

    This study was conducted to determine the effects of a tablet combining losartan/hydrochlorothiazide (L/HCTZ) in comparison with losartan alone in Japanese diabetic patients with hypertension. Thirty consecutive Japanese diabetic patients with hypertension were randomly assigned to group A, receiving losartan alone for the first 3 months, then L/HCTZ for the next 3 months, or group B, receiving L/HCTZ for the first 3 months, then losartan alone for the next 3 months. Clinical and biological parameters were obtained before, and 3 and 6 months after the start of this study. The decreases in systolic and diastolic blood pressure (BP) during treatment with L/HCTZ were significantly greater than in treatment with losartan alone. Both treatments significantly and similarly decreased urinary albumin excretion, the cardio-ankle vascular index (CAVI) and augmentation index (AI). There was no significant difference in metabolic change during both the mono- and combination pharmacotherapies. The tablet combining L/HCTZ significantly reduced systolic and diastolic BP compared with the losartan monotherapy, and offered benefits similar to losartan monotherapy for albuminuria, arterial stiffness assessed by the CAVI and AI, and metabolic effects. Thus, the L/HCTZ tablet could be a useful drug for Japanese diabetic patients with hypertension. PMID:19763132

    To determine the incidence of malignancy and site-specific malignancies in Japanese patients with rheumatoid arthritis (RA). In a prospective large observational cohort study named IORRA, 7,566 patients with RA were enrolled from April 2001 to April 2005 and were followed up to October 2005. Occurrence of malignancy was originally collected by patient reports of IORRA survey biannually from April 2001 to October 2005, and was confirmed by medical records. Standardized incidence rate (SIR) of the observed-to-expected cancer incidence and 95% confidence intervals (95% CI) were then calculated. Factors obtained at first enrollment in IORRA were assessed for association with risk of malignancy using the Cox proportional hazards model. A total of 177 malignancies in 173 patients (58 in men, 115 in women) were identified during the observation period of 25,567 person-years. The age- and sex-standardized incidence rate of malignancy was 437.1 (men, 706.8; women, 366.1) per 100,000 person-years. The SIR of malignancy was slightly excess (SIR 1.18, [95% CI 1.02-1.37]) in all patients, but 1.29 (95% CI 0.99-1.67) in men, and 1.13 (95% CI 0.94-1.36) in women. A significant excess of lymphoma (SIR 6.07, [95% CI 3.71-9.37]) and lung cancer (SIR 2.29, [95% CI 1.57-3.21]), whereas decreased incidence of colorectal cancer (SIR 0.49, [95% CI 0.26-0.83]), were found. Male gender and older age were identified as risk factors for malignancy. A slight excess in the incidence of overall malignancy and highly excess of lymphoma in Japanese RA patients was demonstrated.

    We report a clinicopathological study on 100 japanese patients with peritoneal mesothelioma encountered between 1911 and 1982. Fifty-six were males and 44 were females, they ranged in age from 10 months to 83 years. As the inducement materials, asbestos was reported in 5 and thorium in 2 patients. Clinical symptoms were abdominal distension in 56 and abdominal pain in 50 patients. Thrombocytosis and hypoglycemia were observed in 7 and 3 patients, respectively. Macroscopically, the peritoneal mesothelioma was localized in 7, diffuse in 86 and not described in 7 patients. The pathological classification was benign in 5 and malignant in 77 cases. According to Stout's classification, the peritoneal mesothelioma was tubular in 43 mixed in 25 and fibrous type in 11 cases. Based on our findings we suggest that peritoneal mesotheliomas are on the increase in Japan.

    Isolated 3-methylcrotonyl-CoA carboxylase (MCC) deficiency appears to be the most frequent organic aciduria detected in tandem mass spectrometry (MS/MS) screening programs in the United States, Australia, and Europe. A pilot study of newborn screening using MS/MS has recently been commenced in Japan. Our group detected two asymptomatic MCC deficiency patients by the pilot screening and collected data on another three MCC deficiency patients to study the molecular bases of the MCC deficiency in Japan. Molecular analyses revealed novel mutations in one of the causative genes, MCCA or MCCB, in all five of the patients: nonsense and frameshift mutations in MCCA (c.1750C > T/c.901_902delAA) in patient 1, nonsense and frameshift mutations in MCCB (c.1054_1055delGG/c.592C > T) in patient 2, frameshift and missense mutations in MCCB (c.1625_1626insGG/c.653_654CA > TT) in patient 3, a homozygous missense mutation in MCCA (c.1380T > G/ 1380T > G) in patient 4, and compound heterozygous missense mutations in MCCB (c.569A > G/ c.838G > T) in patient 5. No obvious clinical symptoms were observed in patients 1, 2, and 3. Patient 4 had severe neurological impairment and patient 5 developed Reye-like syndrome. The increasing use of MS/MS newborn screening in Japan will further clarify the clinical and genetic heterogeneity among patients with MCC deficiency in the Japanese population.

    Glomerular filtration rate (eGFR) by serum creatinine (eGFRCr) or standardized cystatin C (eGFRCysC) were estimated in Japanese patients with Graves׳ disease (GD) of different sex. Clinical samples were collected from patients with GD with normal renal function to accurately validate eGFRCr and eGFRCysC levels and evaluate how hyperthyroidism affects renal function. Levels of eGFRCr and eGFRCysC showed clinical usefulness in successfully treated euthyroid patients with GD regardless of sex. The article includes detailed experimental methods and data used in our analysis. The data relates to the "Paradoxical effect of thyroid function on the estimated glomerular filtration rate by serum creatinine or standardized cystatin C in Japanese Graves' disease patients" (Suzuki et al., 2015) [1].

    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

    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 irradiaton 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. Patients who had received pre- or postoperative irradiation were excluded from this evaluation. 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, Pancoasts'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 nuetron 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 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.

    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.

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.

    Isovaleric acidemia (IVA) is an autosomal recessive inborn error affecting leucine metabolism. It is caused by a deficiency in isovaleryl-CoA dehydrogenase (IVD), a mitochondrial matrix enzyme that catalyzes the oxidation of isovaleryl-CoA to 3-methylcrotonyl-CoA. IVD is a FAD-containing enzyme, consisting of four identical subunits. Clinical features of IVA include poor feeding, vomiting, lethargy, developmental delay, metabolic acidosis, and a characteristic "sweaty foot" odor. IVA is one of the target disorders for newborn screening by tandem mass spectrometry (MS/MS). The human IVD gene is located on chromosome 15q. To date, over 50 disease-causing mutations have been reported worldwide. In this study, we searched for IVD mutations in five Japanese patients with IVA (neonatal type, two patients; chronic intermittent type, two patients; and mild biochemical type, one patient). The diagnosis of IVA was confirmed by urinary organic acid analysis using gas chromatography and mass spectrometry. All coding exons and the flanking introns in the IVD gene were amplified by PCR and were directly sequenced. We thus identified six hitherto unknown mutations (p.G94D, p.E116K, p.M167T, p.L243P, p.L246P, and c.696+1G>T) and four previously reported (p.R53P, p.R395C, p.Y403C, and p.E411K) pathogenic mutations. All patients were compound heterozygotes, and each mutation was identified in a single patient. Pathogenicity of newly identified mutations was validated using computational programs. Among them, the p.M167T is believed to influence FAD binding, as the position 167 is present in one of the FAD-binding sites. Our results have illustrated the heterogeneous mutation spectrum and clinical presentation of IVA in the Japanese patients.

    Allan–Herndon–Dudley syndrome (AHDS) is a neurodevelopmental disorder that manifests as intellectual disability and motor developmental delay. Thyroid hormone transporter dysfunction due to SLC16A2 mutation is the underlying cause of this disorder. We identified a novel (P537del) and a recurrent (A150V) SLC16A2 mutation in Japanese AHDS patients from two different families. A150V co-segregated with S33P. Both patients showed similar clinical features including severe neurological features and delayed myelination. Thyroid function showed a common finding of elevated T3 levels. No clear genotype–phenotype correlation was observed in patients with SLC16A2 alterations. PMID:27081503

    Wilson disease is an autosomal recessive disorder with copper metabolism. In Japan, the standard treatment is the administration of copper chelating agents, such as D-penicillamine and trientine. In this study, the authors used zinc acetate to treat Japanese patients with Wilson disease and investigated its efficacy. The 37 patients that comprise this study were found to have Wilson disease using clinical and biochemical tests and were administrated zinc acetate for 48 weeks. The authors followed the clinical symptoms and laboratory findings of the patients by assessing their complete blood counts, biochemical findings, as well as the results of urinalysis and special laboratory tests for copper and zinc metabolism. We also examined side effects of the treatment. Zinc acetate did not aggravate the hepatic or neurological symptoms of any of the patients. Blood biochemical analysis also did not reveal elevation of alanine aminotransferase, aspartate aminotransferase, and γ-glutamyltranspeptidase levels. Zinc treatment did not aggravate the patients' clinical signs and/or laboratory findings. However, it did improve some clinical symptoms of the Wilson disease patients. Although this agent had some side effects, none of them were severe. The authors measured spot urinary copper excretion, which gave an indication of the efficacy of treatment and of the sufficient dosage of zinc. We recommend maintaining a spot urinary copper excretion less than 0.075-μg/mg creatinine. The authors conclude that zinc acetate is an effective and safe treatment for Japanese patients with Wilson disease.

    BACKGROUND—Diffuse panbronchiolitis (DPB), characterised by progressive sinobronchial sepsis, is well characterised in Japanese subjects but not in other ethnic groups. The experience with DPB in seven Chinese patients is described and the clinical profiles compared with those of Japanese subjects.
METHODS—Seven Chinese patients (three women; mean (SD) age 48(18.6) years, all never smokers) who attended a teaching hospital centre and fulfilled the diagnostic criteria for DPB were assessed prospectively for clinical, radiological, lung function, microbiological, and other "characteristic" laboratory parameters.
RESULTS—Lung function assessment showed a typical obstructive pattern (n = 5) and air trapping (n = 7). Typical bronchiolar infiltration by lymphocytes and plasma cells and accumulation of foamy macrophages in the intraluminal tissue were detected in open lung biopsy specimens (n = 2). Chest radiographs and high resolution computed tomographic scans revealed hyperinflation, diffuse nodules, bronchial thickening and dilatation, peripheral hypoattenuation, and bronchiolectasis. Radiological improvement, manifest as a reduction in nodular density and bronchial thickening, and persistence of other abnormalities such as air trapping were not accurately depicted by the classical Nakata or Akira classifications. The other "characteristic" features such as HLA-B54, IgG subclass deficiency, raised CD4/CD8 T lymphocyte ratio, cold haemagglutinaemia, raised IgA, IgG, and rheumatoid factor were not present. Treatment with erythromycin led to excellent responses in symptoms, lung function indices, and the radiological picture. A review of the non-Japanese cases in the literature reveals that this absence of typical "additional features" in DPB might also be applicable to non-Japanese patients.
CONCLUSIONS—We report the only series of non-Japanese Mongoloid patients with well characterised DPB who had uncharacteristic investigation profiles. This experience

    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

    X-linked adrenoleukodystrophy (X-ALD) is a genetic disease associated with demyelination of the central nervous system, adrenocortical insufficiency and accumulation of very long chain fatty acids. It is a clinically heterogeneous disorder ranging from a severe childhood cerebral form to an asymptomatic form. The incidence in Japan is estimated to be between 1:30,000 and 1:50,000 boys as determined by a nationwide retrospective survey between 1990 and 1999, which found no cases with Addison's form. We reviewed the medical records of eleven Japanese boys with X-ALD from 1990 to 2010 in our institute. Eight patients were detected by neuropsychological abnormalities, whereas a higher prevalence of unrecognized adrenocortical insufficiency (5/11: 45%) was observed than previously recognized. While no neurological abnormalities were demonstrated in two brothers, the elder brother had moderate Addison's disease at diagnosis and the presymptomatic younger brother progressed to Addison's disease six months after the diagnosis of X-ALD. Early detection of impaired adrenal function as well as early identification of neurologically presymptomatic patients by genetic analysis is essential for better prognosis. Addison's form might be overlooked in Japan; therefore, X-ALD should be suspected in patients with adrenocortical insufficiency.

    Active usage of observational pain scales in Japanese aged-care facilities has not been previously described. Therefore, to examine the feasibility and clinical utility of the Abbey Pain Scale-Japanese version (APS-J), this study examined the interrater reliability of the APS-J among a researcher, nurses, and care workers in aged-care facilities in Japan. This study also aimed to obtain nurses' and care workers' opinions on use of the scale. The following data were collected from 88 residents of two aged-care facilities: demographics, Barthel Index, Folstein Mini-Mental Examination (MMSE), 15-item Geriatric Depression Scale (GDS-15), and APS-J for pain. The researchers, nurses, and care workers independently assessed the residents' pain by using the APS-J, and intraclass correlation coefficients (ICC) for interrater reliability and Cronbach alpha for internal consistency were examined. The ICC between researchers and nurses, researchers and care workers, and nurses and care workers were 0.68, 0.74, and 0.76, respectively. Nurses and care workers were invited for focus group interviews to obtain their opinions regarding APS-J use. During these interviews, nurses and care workers stated that the observational points of APS-J subscales were the criteria they normally used to evaluate residents' pain. Several nurses and care workers reported a gap between the estimated pain intensity and APS-J score. Unclear APS-J criteria, difficulties in observing residents, and insufficient practice guidelines were also reported. Our findings indicate that the APS-J has moderate reliability and clinically utility. To facilitate APS-J usage, education and clinical guidelines for pain management may be required for nurses and care workers.

    The possible relationship between changes in peripheral hormone levels and the occurrence of prostatic pathology was studied in a case-control study, involving estimation of various plasma hormones in 368 Dutch and 258 Japanese men, who were grouped as controls and patients with benign prostatic hyperplasia, focal prostatic carcinoma, or clinically evident prostatic carcinoma. Results of a number of previous, smaller studies concerning interrelationships between hormone levels in elderly men were confirmed within the Dutch and Japanese groups. Plasma levels of testosterone and estradiol were significantly lower in the Japanese men, when compared with those in Dutch men. Probably as a result of this difference in testosterone levels, the ratio between serum levels of testosterone and sex hormone-binding globulin (SHBG) was decreased in the Japanese men, while the ratio between the concentrations of dihydrotestosterone and testosterone was increased. These differences were also found when results from Japanese subgroups (controls and patients with prostate pathology) were compared with those from the Dutch subgroups. There were no significant differences in plasma androgen levels between Japanese or Dutch prostate cancer cases and their respective control subgroups. These findings do not support a correlation between the lower plasma testosterone levels and a lower incidence of prostate cancer in the Japanese men. Furthermore, no significant differences were found between salivary levels of testosterone or the ratio between testosterone and SHBG in the various Dutch subgroups. In Japanese benign prostatic hyperplasia patients, the testosterone to SHBG ratio was significantly increased. In conclusion, the results of this retrospective, cross-sectional study do not indicate that hormonal levels play a primary role in the origin or promotion of prostatic abnormalities. The finding of a lower plasma testosterone in the Japanese men, however, remains suggestive

    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.

    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.

    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

    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 aim of this study was to evaluate the clinical factors, drug-related genetic polymorphisms, and human leukocyte antigen (HLA) types to determine the association with sorafenib-induced high-grade skin rash (HGSR) in Japanese patients with advanced renal cell carcinoma (RCC). A total of 55 patients with advanced RCC treated with sorafenib were analyzed retrospectively. Of these, 33 patients were subjected to HLA typing and polymorphism analyses of CYP3A5, ABCB1, ABCC2, and UGT1A1, which are involved in the metabolism and membrane transport of sorafenib. Grade 3 or higher SR developed in 12 (22%), and a higher incidence was observed in female patients than in male patients (40 vs. 15%, P=0.046). The initial dose, initial dose per body weight, and initial dose per body surface area in patients with HGSR were significantly higher than those in patients without HGSR. Patients with the ABCC2 -24CC genotype were at a significantly higher risk of SR than those with the CT genotype (35 vs. 0%, P=0.032). HLA-A*24 was significantly associated with the occurrence of HGSR (P=0.049). Our finding suggested that women, higher initial dose per body weight or body surface area, the ABCC2 -24CC genotype, and HLA-A*24 are associated with the risk of sorafenib-induced HGSR in Japanese RCC patients.

    The somatostatin analog lanreotide Autogel has proven to be efficacious for treating acromegaly in international studies and in clinical practices around the world. However, its efficacy in Japanese patients has not been extensively evaluated. We examined the dose-response relationship and long-term efficacy and safety in Japanese patients with acromegaly or pituitary gigantism. In an open-label, parallel-group, dose-response study, 32 patients (29 with acromegaly, 3 with pituitary gigantism) received 5 injections of 60, 90, or 120 mg of lanreotide Autogel over 24 weeks. Four weeks after the first injection, 41% of patients achieved serum GH level of <2.5 ng/mL and insulin-like growth factor-I (IGF-I) level was normalized in 31%. Values at Week 24 were 53% for GH and 44% for IGF-I. Dose-dependent decreases in serum GH and IGF-I levels were observed with dose-related changes in pharmacokinetic parameters. In an open-label, long-term study, 32 patients (30 with acromegaly, 2 with pituitary gigantism) received lanreotide Autogel once every 4 weeks for a total of 13 injections. Dosing was initiated with 90 mg and adjusted according to clinical responses at Weeks 16 and/or 32. At Week 52, 47% of patients had serum GH levels of <2.5 ng/mL and 53% had normalized IGF-I level. In both studies, acromegaly symptoms improved and treatment was generally well tolerated although gastrointestinal symptoms and injection site induration were reported. In conclusion, lanreotide Autogel provided early and sustained control of elevated GH and IGF-I levels, improved acromegaly symptoms, and was well tolerated in Japanese patients with acromegaly or pituitary gigantism.

    The somatostatin analog lanreotide Autogel has proven to be efficacious for treating acromegaly in international studies and in clinical practices around the world. However, its efficacy in Japanese patients has not been extensively evaluated. We examined the dose-response relationship and long-term efficacy and safety in Japanese patients with acromegaly or pituitary gigantism.

    Cisplatin, cis-Dichlorodiammine platinum (II) (CDDP) remains a major antineoplastic drug for the treatment of solid tumors. Its chief dose-limiting side effect is nephrotoxicity. To make a safe and effective dosing regimen of a drug excreted mainly by the renal route, evaluation of patients' renal function is essential. Creatinine clearance (CLcr) or glomerular filtration rate (GFR) is considered to be a standard renal-function test. Several equations have been used in clinical settings, to predict CLcr and GFR using serum creatinine concentration. We carried out a retrospective analysis of the correlation between 24-hour CLcr measured by a urine collection method; and the predicted CLcr and GFR estimated by various equations such as Jelliffe, Yasuda, Orita, Mawer, Mawer, MDRD and modified MDRD, and Cockcroft-Gault. This study used data from Japanese head-and-neck cancer patients, before and after chemotherapy with CDDP. Slopes of regression lines of scatter plots between measured CLcr and predicted renal function in post-CDDP patients were less compared to pre-CDDP patients. On the other hand, Y-intercepts were noted in the scatter plots on renal function from all equations. These results suggest that evaluation of renal function using predictive formulae may have been over-/under-estimated after CDDP administration. PMID:24147348

    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

    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

  14. 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

    Family history and nutritional status may affect the long-term prognosis of stomach cancer, but evidence is insufficient and inconsistent. To clarify the prognostic factors of stomach cancer, we conducted a prospective study of 1,033 Japanese patients with histologically confirmed stomach cancer who were admitted to a single hospital between 1997 and 2005. Family history of stomach cancer and pretreatment body mass index (BMI) were assessed using a self-administered questionnaire. Clinical data were retrieved from a hospital-based cancer registry. All patients were completely followed up until December, 2008. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated according to family history in parents and siblings and BMI category. During a median follow-up of 5.3 years, 403 all-cause and 279 stomach cancer deaths were documented. Although no association with family history was observed in the patients overall, analysis according to age group found an increased risk of all-cause death associated with a history in first degree relatives (HR = 1.61, 95% CI: 0.93-2.78, p = 0.09) and with a parental history (HR = 1.86, 95% CI: 1.06-3.26) among patients aged under 60 years at diagnosis. BMI was related to all-cause and stomach cancer death among patients aged 60 and over, showing a J-shaped pattern (HR of all-cause death = 2.28 for BMI < 18.5; HR = 1.61 for 25 ≤ vs. ≥ 23.0 to < 25.0 kg/m(2)). A family history of stomach cancer, especially parental history, may affect mortality among younger stomach cancer patients, whereas nutritional status may be a prognostic factor in older patients.

    Sleep-disordered breathing (SDB), especially sleep apnea-hypopnea syndrome (SAS), is often observed in patients with active acromegaly. This complication is a risk factor for cardiovascular disease and associated with increased morbidity and mortality in acromegaly. However there is little information on SDB in Japanese patients with acromegaly. We investigated the prevalence of SDB and association between the severity of SDB and various features and biomarkers in Japanese patients with acromegaly. Twenty-four Japanese patients with active acromegaly underwent overnight cardiorespiratory monitoring, hormonal assays and cephalometric measurements on X-ray. A high prevalence of SDB was detected in acromegaly (87.5%). Log apnea-hypopnea index (AHI) correlated positively with soft palate length / body height (X-ray) (r=0.44, p=0.043), but not with log growth hormone levels and insulin-like growth factor type-1 standard deviation scores, size of pituitary adenoma, disease duration, body mass index, waist circumference, estimated visceral fat area, heel pad thickness / height, tongue thickness/ height, or oropharyngeal dimension/ height. In conclusion, our study demonstrated a high prevalence of SDB in Japanese patients with acromegaly, and its severity correlated with soft palate length. Based on the high incidence of SDB identified in the present study, we recommend that all patients with acromegaly are routinely screened for SDB for early diagnosis and treatment.

    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

    Retrospective investigations of odontomas in Japanese children and one recurrent case were carried out. Thirty-nine cases of odontoma in 38 children were treated in the Paediatric Dentistry Clinic of Niigata University Dental Hospital between September 1979 and December 2002. The patients consisted of 23 males and 15 females and their ages ranged from 1 year 2 months to 14 years old. The chief complaints were delayed tooth eruption in 19 cases (five: primary teeth, 14: permanent teeth), retention of primary teeth in 11, incidentally found on the radiographic examination in eight cases, and swelling of the jaw in one case. Thirty-four cases (87%) were associated with tooth eruption disturbances. The most frequently affected region was the maxillary anterior region. Treatment consisted of surgical removal of odontomas in all cases, after which if the impacted teeth did not erupt, exposure of the crown and/or orthodontic traction was performed. Pathological diagnoses were compound odontoma in 30 cases, complex odontoma (n = 7), and compound and complex odontoma (n = 2). A retrospective study of the radiographs revealed the developing process of odontomas in four cases and odontoma disturbed tooth eruption since the early uncalcified developing stage. A recurrent case was a boy aged 6 years 5 months in whom the first surgical removal of odontoma was performed at the age of 1 year 8 months. Recurrence of an odontoma is very rare, but in very young children odontomas are in the early developing stages, containing uncalcified portions, so it is important to perform periodical observations until the succedaneous teeth erupt.

    The Calvert formula, that is, carboplatin dose (mg) = target area under the concentration versus time curve (AUC) × (glomerular filtration rate [GFR] + 25), has not been validated in Japanese subjects in whom the GFR was accurately measured. The purpose of this study is to evaluate the validity of this formula for Japanese patients with cancer and modify it for this population. The GFR was measured on the basis of inulin clearance, which is considered to reflect the accurate GFR. Inulin clearance was measured in 28 patients with cancer. The adjusted 24-h creatinine clearance (24-h Ccr) was unbiased (mean prediction error [MPE] ± SE = -2.3 ± 4.5%) and acceptably precise (root mean squared error = 23.7%) for GFR assessment. The pharmacokinetics of carboplatin were analyzed in 21 patients with a GFR of 17.2-91.4 mL/min. The original Calvert formula overestimated carboplatin clearance, resulting in an MPE of 14.3%. When we revised the Calvert formula for Japanese patients by substituting a non-renal clearance of 15 for 25, that is, dose = target AUC × (GFR + 15), the MPE decreased to -0.1% (P < 0.001). We conclude that the adjusted 24-h Ccr is acceptably precise for GFR assessment, and the non-renal clearance of carboplatin is suggested to be lower in Japanese patients with cancer than in their Western counterparts.

    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.

    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

    The Japanese language is represented by two different codes: syllabic and logographic while Portuguese employs an alphabetic writing system. Studies on bilingual Portuguese-Japanese individuals with acquired dyslexia therefore allow an investigation of the interaction between reading strategies and characteristics of three different writing codes. The aim of this study was to examine the differential impact of an acquired brain lesion on the reading of the logographic, syllabic and alphabetic writing systems of a bilingual Portuguese-Japanese aphasic patient (PF). Results showed impaired reading in the logographic system and when reading irregularly spelled Portuguese words but no effects on reading regular words and nonwords in syllabic and alphabetic writing systems. These dissociations are interpreted according to a multi-route cognitive model of reading assuming selective damage in the lexical route can result in acquired dyslexia across at least three different writing codes.

    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

    The quality of commercially sponsored clinical studies in Japan was examined with reference to deficiencies in the audit reports issued by the Organization for Pharmaceutical Safety and Research (OPSR). The OPSR is responsible for domestic good clinical practice auditing in Japan. Routine audits from 1997 to 2000 for 331 hospitals revealed various types of deficiencies such as errors in case report form (CRF) entries, institutional review board problems, and protocol deviations. The high prevalence of CRF-related deficiencies seemed to stem from peculiarities of the Japanese study environment such as the historical lack of on-site monitoring by the sponsor and the absence of research nurses. Characteristics in usual medical practices such as multiple drug use and loose informed consent also seemed to be associated with prevalence of similar deficiencies in clinical trials.

    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

    To clarify whether the new Japanese glomerular filtration rate (eGFR) equation was able to accurately determine the initial and individualized dosage adjustment concentrations of vancomycin (VCM), the predictive performance for VCM concentrations using the eGFR and Cockcroft-Gault (CG) equations was compared. Data were retrospectively collected from clinical records of 90 patients with MRSA infection whose trough and peak VCM concentrations had been determined. The predicted VCM initial and individualized dosage adjustment concentrations were performed with the 2-compartment linear model using pharmacokinetic parameter means and their individual values via Bayesian estimation, respectively. The prediction error (PE) and its absolute value (APE) between the observed and predicted VCM concentrations were calculated as indices of bias and accuracy in predictive performance, respectively. In the initial dosage adjustment of VCM, the PE value, calculated with the eGFR equation in trough and peak VCM concentrations of patients whose BMI were 18.5 kg/m(2) and higher, was significantly smaller than that calculated with the CG equation. In particular, both PE and APE values obtained from the eGFR calculated concentrations from nonelderly patients (younger than 65 years old) were significantly improved compared with those from the CG equation. In the individualized dosage adjustment of VCM, the eGFR equation gave a significantly smaller PE value in nonelderly patients' trough concentrations than the CG equation. These findings provide useful information for adjusting the VCM dosage to achieve optimal therapeutic efficacy in patients with MRSA infection.

    Background and study aims: Better endoscopic diagnosis in case of Barrett’s esophagus is still needed. White globe appearance (WGA) is a novel endoscopic marker for gastric adenocarcinoma, with high sensitivity for differentiating between gastric cancer/high-grade dysplasia and other lesions. We report 2 cases of esophageal adenocarcinoma with WGA. In Case 1, esophagogastroduodenoscopy (EGD) revealed a 10-mm esophageal adenocarcinoma in a 48-year-old Japanese woman with short-segment Barrett’s esophagus. A small (< 1 mm) white globular lesion, typical of WGA, was observed under the epithelium by magnifying narrow-band imaging. A dilated neoplastic gland with eosinophilic material and necrotic epithelial fragments was identified at the site of the WGA by histologic examination. In Case 2, EGD revealed a 5-mm esophageal adenocarcinoma in a 60-year-old Caucasian man with long-segment Barrett’s esophagus. A typical WGA was observed by magnifying narrow-band imaging and similar histologic findings were identified at the site of the WGA. WGA could be a reliable endoscopic finding for target biopsy in esophageal adenocarcinoma, if its specificity is as high as in gastric cancer. The clinical implications of WGA in patients with Barrett’s esophagus should be investigated further. PMID:27747281

    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

    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.

    Xeroderma pigmentosum (XP) is an autosomal recessive genetic disorder characterized by extraordinary sensitivity to sunlight, resulting in cutaneous malignant tumors. Among XP, XP-F presents relatively uniquely in Japanese. To clarify the characteristics of this group, we describe a case of XP-F and review Japanese cases previously reported. A 50-year-old Japanese woman was referred to us with multiple, variously sized, light- or dark-brown macules on the face and sunlight-exposed extremities. She had experienced bulla formation with approximately 10 min of sunlight exposure during her elementary school years. Her parents had been first cousins, and her mother and sister had photosensitivity. She showed no neurological or developmental abnormalities. Ultraviolet (UV) irradiation testing revealed normal levels for minimal erythema dose with UV-A and UV-B. Sensitivity to UV-C and DNA repair ability in the patient's fibroblasts were indicated between that in normal individuals and that in an XP-A patient. Complementation assay revealed that transfection of the XPF gene led most efficient DNA repair compared with the other XP genes. Therefore, the patient was diagnosed with XP-F. Twenty-three cases of Japanese patients (six males, 17 females) with XP-F have been reported, including the present case. Our review suggested a relatively high prevalence of 50% (11/22) for cutaneous malignant tumors. A significant difference was evident in the mean age at first medical consultation between patients with cutaneous malignant tumors (53.6 years) and patients without such tumors (30.8 years). This suggests that cutaneous malignant tumors could occur in the age range of 30-50 years in XP-F patients. PMID:26010807

    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

    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.

    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

    Carmustine (BCNU) implants (Gliadel® Wafer, Eisai Inc., New Jersey, USA) for the treatment of malignant gliomas (MGs) were shown to enhance overall survival in comparison to placebo in controlled clinical trials in the United States and Europe. A prospective, multicenter phase I/II study involving Japanese patients with MGs was performed to evaluate the efficacy, safety, and pharmacokinetics of BCNU implants. The study enrolled 16 patients with newly diagnosed MGs and 8 patients with recurrent MGs. After the insertion of BCNU implants (8 sheets maximum, 61.6 mg BCNU) into the removal cavity, various chemotherapies (including temozolomide) and radiotherapies were applied. After placement, overall and progression-free survival rates and whole blood BCNU levels were evaluated. In patients with newly diagnosed MGs, the overall survival rates at 12 months and 24 months were 100.0% and 68.8%, and the progression-free survival rate at 12 months was 62.5%. In patients with recurrent MGs, the progression-free survival rate at 6 months was 37.5%. There were no grade 4 or higher adverse events noted due to BCNU implants, and grade 3 events were observed in 5 of 24 patients (20.8%). Whole blood BCNU levels reached a peak of 19.4 ng/mL approximately 3 hours after insertion, which was lower than 1/600 of the peak BCNU level recorded after intravenous injections. These levels decreased to less than the detection limit (2.00 ng/mL) after 24 hours. The results of this study involving Japanese patients are comparable to those of previous studies in the United States and Europe. PMID:24739422

    This study was undertaken to determine the absolute and relative value of blood vessel invasion (BVI) using both factor VIII-related antigen and elastica van Gieson staining, proliferating cell nuclear antigen (PCNA), p53, c- erb B-2, and conventional prognostic factors in predicting relapse-free survival (RFS) and overall survival (OS) rates associated with long-term survival in Japanese patients with node-negative breast cancer. Two hundred patients with histological node-negative breast cancer were studied. We investigated nine clinicopathological factors, including PCNA, p53, c- erb B-2 using permanent-section immunohistochemistry, clinical tumour size (T), histological grade (HG), mitotic index (MI), tumour necrosis (TN), lymphatic vessel invasion (LVI) and BVI, followed for a median of 10 years (range 1–20). Twenty-one patients (10.5%) had recurrence and 15 patients (7.5%) died of breast cancer. Univariate analysis showed that BVI, PCNA, T, HG, MI, p53, c- erb B-2 and LVI were significantly predictive of 20-year RFS or OS. Multivariate analysis showed that BVI (P = 0.0159, P = 0.0368), proliferating cell nuclear antigen (PCNA) (P = 0.0165, P = 0.0001), and T (P = 0.0190, P = 0.0399) were significantly independent prognostic factors for RFS or OS respectively. BVI, PCNA and T were independent prognostic indicators for RFS or OS in Japanese patients with node-negative breast cancer and are useful in selecting high-risk patients who may be eligible to receive strong adjuvant therapies. © 2000 Cancer Research Campaign PMID:10646896

    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.

    Concurrent treatments with bisphosphonates and vitamin K are promising given that bisphosphonates possibly interfere with vitamin K activation. This is a prospective, multi-center, open-labeled, randomized trial of the efficacy of concurrent treatment with vitamin K2 and risedronate compared with risedronate alone and to explore subsets of patients for which concurrent treatment is particularly efficacious (trial identification number UMIN000000991). Inclusion criteria are women who meet the criteria for pharmacological therapy for osteoporosis, aged ≥65 years, have any of pre-specified risk factors, can walk unassisted, and are able to answer questionnaires. Exclusion criteria are prior warfarin use, secondary osteoporosis or non-osteoporotic metabolic bone diseases, contraindication for vitamin K2 and risedronate, hyper- or hypoparathyroidism, mental disorders, prevalent vertebral fracture at ≥6 sites, severe degenerative spinal deformation between T4 and L4, serious heart, liver, or kidney disease, or bisphosphonate use within the previous 6 months. Patients were recruited from 123 institutes between January 2008 and February 2010, and allocated to vitamin K2 (45 mg/day) and risedronate (2.5 mg/day or 17.5 mg/week) or risedronate alone (2.5 mg/day or 17.5 mg/week) groups. Primary endpoint is a vertebral or non-vertebral fracture. Secondary endpoints are bone mineral density, height, undercarboxylated osteocalcin, JOQOL, EQ-5D and safety. A sample size of 910 subjects per group and 2-year follow-up will provide 80 % power to detect 35 % risk reduction for fracture, with a two-sided significance level of 5 %. Subgroup analysis stratified to adjustment factors for random allocation, body mass index, 25-hydroxyvitamin D, estimated glomerular filtration rate, grade of vertebral fracture, JOQOL, EQ-5D, and co-morbidity is pre-specified.

    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.

    Combined thrombo-prophylaxis with mechanical and pharmacological methods is recommended in patients undergoing total knee or hip arthroplasty. As patients with 'untreated inherited bleeding disorders such as haemophilia' are at risk of bleeding, no prophylaxis has been prescribed for these patients. However, a retrospective study reported subclinical deep venous thrombosis (DVT) in 10% of patients with haemophilia undergoing major orthopaedic surgery. In this study, we aimed to evaluate the risk of DVT after total knee arthroplasty (TKA). We examined 38 TKA in 33 Japanese patients with haemophilia using ultrasonography. We did not detect DVT. The risk of DVT in patients with haemophilia after TKA may be lower than that in the general population. However, as patients with haemophilia progress in age, venous thromboembolism should be considered as a potential problem.

    This study aimed to detail the clinicopathologic features of endometrial carcinomas that developed in Japanese patients receiving adjuvant tamoxifen treatment for breast cancer patients. Ten endometrial carcinomas in tamoxifen-treated breast cancer patients were collected from two medical centers. The endometrial carcinomas included two stage Ia, four stage Ib, two stage Ic and two stage IIIc. Three tumors were Grade 1, six were Grade 2, and one was Grade 3. The tumor was limited to the endometrium in two cases. Myometrial invasion was limited to the inner half of the myometrium in five cases and involved the outer half in three. A mild degree of lymphovascular space invasion was identified in five cases. Deep cervical invasion was recognized in one case. The cell types comprised nine endometrioid adenocarcinomas and one serous carcinoma. Five of eight postmenopausal endometrial carcinomas were associated with polypoid endometrial lesions composed of cystically dilated atrophic and proliferative glands widely separated by fibrotic stroma. Two patients with retroperitoneal lymph node metastases died of endometrial cancer. One patient developed a contralateral breast cancer during tamoxifen treatment. No patient died of breast cancer. We did not demonstrate a higher frequency of either high-grade tumors or unfavorable histologic subtypes in tamoxifen-treated Japanese breast cancer patients.

    Metabolic syndrome confers an increased risk of cardiovascular disease (CVD) in the general population. The relationship between adiponectins, and clinical outcomes in patients undergoing hemodialysis remains controversial. We investigated whether adiponectins, biomarkers of inflammation, nutrition status and clinical features predict the mortality of patients undergoing hemodialysis for 6 years. We measured baseline plasma total and high-molecular-weight (HMW) adiponectins, tumor necrosis factor (TNF)-α, serum high sensitivity C-reactive protein (hsCRP), and clinical characteristics including visceral fat area (VFA) and the Geriatric Nutritional Risk Index (GNRI) in 133 patients undergoing chronic hemodialysis. Forty-one of the 133 patients died during follow-up. The deceased patients were significantly older, had more prior CVD and diabetes, higher TNF-α and hsCRP levels but lower GNRI. VFA, and total and HMW adiponectin did not significantly differ between the two groups. TNF-α and hsCRP levels and GNRI score were significant for predicting all-cause and cardiovascular mortality in receiver operating curve analyses. When stratified by a GNRI score of 96, Cox proportional hazards analyses identified TNF-α as a significant predictor of all-cause mortality (hazard ratio [HR] 1.23; P = 0.038) and hsCRP as a significant predictor of all-cause and cardiovascular mortality (HR, 2.32, P = 0.003; HR 2.30, P = 0.012, respectively) after adjusting for age, sex, diabetes mellitus, and prior CVD, only in malnourished patients. These results demonstrate that malnutrition and the inflammatory markers TNF-α and hsCRP, but not metabolic markers, including VFA and adiponectins have a significant impact on 6-year all-cause and cardiovascular mortality in Japanese patients undergoing hemodialysis.

    Homocysteine is a sulfhydryl-containing amino acid that is derived from dietary methionine, and there has been increasing evidence that elevated plasma homocysteine levels are associated with increased risk of cardiovascular diseases, including carotid, coronary and peripheral arterial disease (PAD). The association of plasma homocysteine levels with peripheral vascular involvements, such as Raynaud phenomenon (RP), digital ulcers (DU) in systemic sclerosis (SSc) patients has not been well studied. The objective of this study was to examine plasma homocysteine levels and their clinical associations in patients with SSc. Plasma homocysteine levels in 151 Japanese patients with SSc and 20 healthy controls were examined. No significant differences were observed in plasma homocysteine levels between SSc patients and healthy individuals. Demographic and clinical features of the SSc patients revealed that severe skin sclerosis, anti-topoisomerase I antibody positivity, complications of DU, acro-osteolysis (AO) and interstitial lung disease (ILD) were significantly more prevalent among the patients with elevated plasma homocysteine levels. The plasma homocysteine levels were positively correlated with modified Rodnan total skin score. The plasma homocysteine levels in the SSc patients with DU, AO and ILD were significantly higher than those in the SSc without DU, AO and ILD, respectively. Plasma homocysteine levels did not correlate with either the mean or max intima-media thickness (IMT) or plaque score, suggesting that plasma homocysteine levels might not be associated with carotid artery atherosclerosis in SSc patients. The measurement of plasma homocysteine levels in SSc patients might be useful for the risk stratifications of severe skin sclerosis, DU and AO.

    The physical benefits of subthalamic nucleus deep brain stimulation (STN-DBS) in Parkinson's disease (PD) patients are well documented, but the mental benefits are uncertain, particularly in Japanese patients. This study evaluated the clinical and neuropsychological characteristics before and after STN-DBS surgery in Japanese PD patients. PD patients (n=13, age 67.0 ± 7.8 years) were evaluated pre-surgery (baseline) and at 1 and 6 months post-surgery by two trained psychiatrists. The motor symptoms were assessed by the Unified Parkinson's Disease Rating Scale (UPDRS) motor score. The neuropsychological and psychiatric tests performed were the Mini-Mental State Examination, the Wisconsin Card Sorting Test (WCST), the Verbal Fluency Test (VFT), the Hamilton Depression Rating Scale and the Hamilton Anxiety Rating Scale (HAM-A). The UPDRS motor score (p<0.001) and HAM-A score (p=0.004) showed significant improvement at 1 month post-surgery, but a significant decline was observed in the WCST total error (p=0.005) and the semantic VFT score (p<0.001). The phonetic VFT also showed a substantial decline (p=0.015) at 1 month post-surgery. At 6 months post-surgery, the improvement in the UPDRS motor score was maintained, and the scores on the neuropsychological and psychiatric tests had returned to baseline. Although bilateral STN-DBS did not appear to have long-term effects on neuropsychological and psychiatric outcomes, the microlesion effects associated with STN-DBS appear to increase the risk of transient cognitive and psychiatric complications. These complications should be monitored by careful observation of neurological and psychiatric symptoms.

    Pruritus affects many patients undergoing hemodialysis (HD). In this study, pruritus and its relationship to morbidity, quality of life (QoL), sleep quality, and patient laboratory measures were analyzed in a large sample of Japanese patients undergoing HD. Severity of patient-reported pruritus symptoms experienced during a 4-week period was collected from 6480 Japanese patients undergoing HD in three phases of the Dialysis Outcomes and Practice Patterns Study (DOPPS; 1996-2008; 60-65 study facilities/phase). Adjusted linear and logistic regressions were used to identify associations of pruritus with treatment parameters and QoL outcomes. Adjusted Cox regressions examined the influence of pruritus severity on mortality. Moderate to extreme pruritus was experienced by 44% of prevalent patients undergoing HD in the Japanese Dialysis Outcomes and Practice Patterns Study. Many patient characteristics were significantly associated with pruritus, but this did not explain the large differences in pruritus among facilities (20-70%). Pruritus was slightly less common in patients starting HD than in patients on dialysis >1 year. Patients with moderate to extreme pruritus were more likely to feel drained (adjusted odds ratio = 2.2-5.8, P < 0.0001), have poor sleep quality (adjusted odds ratio = 1.9-3.7, P < 0.0001), and have QoL mental and physical composite scores 2.3-6.7 points lower (P < 0.0001) than patients with no/mild pruritus. Pruritus in patients undergoing HD was associated with a 23% higher mortality risk (P = 0.09). The many poor outcomes associated with pruritus underscore the need for better therapeutic agents to provide relief for the 40-50% of prevalent patients undergoing HD substantially affected by pruritus. Pruritus in new patients with end-stage renal disease likely results from uremia or pre-existing conditions (not HD per se), indicating the need to understand development of pruritus before end-stage renal disease.

    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

    To investigate the occurrence of a writing defect, omission of kana letters (OKL), in intellectually normal Japanese patients with amyotrophic lateral sclerosis (ALS), and define the neuroimaging profile of OKL. Sixteen Japanese adults (10 men and 6 women), similar in age (mean 62.9 +/- 9.9 years) and level of education (mean 12.6 +/- 2.13 years), with early-stage, classical ALS (mean duration 15.9 +/- 5.45 months) were investigated, including tests of motor function and ALS progression; intellectual function including writing ability; and neuroimaging, with follow-up of 1 year. Main outcome measures were as follows: Raven's Colored Progressive Matrices (RCPM: intellect and psychomotor speed); one-minute verbal fluency measurement; paired associate word-learning test (PAWLT); Western Aphasia Battery (WAB); moraic segmentation test; magnetic resonance imaging (MRI); and (123)I-isopropyl amphetamine ((123)I-IMP) or (99m)Tc-ethylcysteinate dimmer (ECD) single photon emission tomography (SPECT). Three patients (18.8%) showed OKL (WAB), with disturbance in moraic segmentation. One patient showed decreased blood flow to the bilateral frontal lobes by (123)I-IMP-SPECT. Patients with OKL did not differ significantly from those without in the RCPM (intellect), RCPM (time), verbal fluency, or PAWLT (p = 0.10, 0.84, 0.63, 0.55). Although motor dysfunction and weakness progressed during follow-up, none developed symptoms of dementia. The OKL may develop as a relatively early cognitive symptom in intellectually normal Japanese patients with classical ALS. The neuroimaging profile of OKL remains uncertain.

    Fructose-1,6-bisphosphatase (FBPase) deficiency is an autosomal recessive inherited disorder and may cause sudden unexpected infant death. We reported the first case of molecular diagnosis of FBPase deficiency, using cultured monocytes as a source for FBPase mRNA. In the present study, we confirmed the presence of the same genetic mutation in this patient by amplifying genomic DNA. Molecular analysis was also performed to diagnose another 12 Japanese patients with FBPase deficiency. Four mutations responsible for FBPase deficiency were identified in 10 patients from 8 unrelated families among a total of 13 patients from 11 unrelated families; no mutation was found in the remaining 3 patients from 3 unrelated families. The identified mutations included the mutation reported earlier, with an insertion of one G residue at base 961 in exon 7 (960/961insG) (10 alleles, including 2 alleles in the Japanese family from our previous report [46% of the 22 mutant alleles]), and three novel mutations--a G-->A transition at base 490 in exon 4 (G164S) (3 alleles [14%]), a C-->A transversion at base 530 in exon 4 (A177D) (1 allele [4%]), and a G-->T transversion at base 88 in exon 1 (E30X) (2 alleles [9%]). FBPase proteins with G164S or A177D mutations were enzymatically inactive when purified from E. coli. Another new mutation, a T-->C transition at base 974 in exon 7 (V325A), was found in the same allele with the G164S mutation in one family (one allele) but was not responsible for FBPase deficiency. Our results indicate that the insertion of one G residue at base 961 was associated with a preferential disease-causing alternation in 13 Japanese patients. Our results also indicate accurate carrier detection in eight families (73%) of 11 Japanese patients with FBPase deficiency, in whom mutations in both alleles were identified.

    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

    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

    This interim analysis of postmarketing surveillance data for adalimumab-treated rheumatoid arthritis (RA) patients summarizes safety and effectiveness during the first 24 weeks of therapy for the first 3,000 patients treated in Japan (June 2008-December 2009). Patient eligibility for antitumor necrosis factor therapy was based on the Japanese College of Rheumatology treatment guidelines and Japanese labeling. All patients were screened for tuberculosis. Approximately 50% of the population was biologic naïve, 66% received concomitant methotrexate (MTX), and 72% received concomitant glucocorticoids. The overall incidence rate of adverse events was 31% (5.5% serious) and that of adverse drug reactions (ADRs) was 27% (4.1% serious). Incidence rates of ADRs and serious ADRs were similar regardless of prior biologic therapy or concomitant MTX use but were significantly higher in patients receiving glucocorticoids compared with those not receiving glucocorticoids. Bacterial/bronchial pneumonia occurred in 1.2% of patients; interstitial pneumonia, 0.6%; Pneumocystis jirovecii pneumonia, 0.3%; tuberculosis, 0.13%; and administration-site reactions, 6.1%. Mean 28-joint Disease Activity Scores decreased significantly after 24 weeks from 5.29 to 3.91. All subgroups showed significant improvement, particularly the biologic-naïve patients receiving concomitant MTX. No new safety concerns were identified. ADR Incidence rates were similar to those of other biologic agents approved for RA.

    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.

    B-cell activating factor (BAFF) promotes the survival and adhesion of multiple myeloma (MM) cells. Tabalumab (LY2127399) is an anti-BAFF monoclonal antibody. This phase 1, multicenter, open-label, nonrandomized, dose-escalation study evaluated the safety, tolerability, pharmacokinetics, pharmacodynamics and efficacy of tabalumab in combination with bortezomib and dexamethasone in Japanese patients with relapsed or refractory MM (RRMM). Sixteen patients received intravenous i.v. tabalumab 100 mg (Cohort 1, n = 4) or i.v. tabalumab 300 mg (Cohort 2, n = 12) in combination with oral dexamethasone 20 mg/day and i.v. or s.c. bortezomib 1.3 mg/m(2) . All patients had treatment-emergent adverse events (TEAE) possibly related to study treatment; the most common TEAE were thrombocytopenia (81.3%), lymphopenia (43.8%) and increased alanine aminotransferase (43.8%). Two (20.0%) dose-limiting toxicities were observed, both in Cohort 2 (tabalumab 300 mg), which was below the predefined cutoff for tolerability (<33%). The pharmacokinetics of tabalumab were similar when bortezomib was coadministered i.v. versus s.c. The overall response rate was 56.3%, suggesting that the combined treatment was effective. In conclusion, combined treatment with these three agents was well tolerated in this population of Japanese patients with RRMM. The study was registered at www.clinicaltrials.gov (NCT01556438).

    Congenital adrenal hyperplasia due to steroid 21-hydroxylase deficiency (21-OHD) is an autosomal recessive disorder caused by the defective CYP21A2 gene that leads to various degrees of impaired secretion of both cortisol and aldosterone. In the present study, we analyzed the CYP21A2 gene in a Japanese male patient with 21-OHD and functionally characterized the mutant CYP21A2 gene. The patient presented with hypoglycemia and a salt-losing crisis during the neonatal period, and was diagnosed as having the salt-wasting form of 21-OHD based on the clinical and laboratory findings. Analysis of the CYP21A2 gene revealed that the patient is homozygous for a novel C to A conversion at -9 position of intron 9 (IVS9-9C>A) and that his parents are heterozygous for the IVS9-9C>A mutation. Transient expression of the IVS9-9C>A mutant CYP21A2 gene in COS-1 cells demonstrated that the mutation creates an aberrant splice acceptor site at -7 position of intron 9 and totally inactivates the authentic splice acceptor site of intron 9, which results in complete deficiency of 21-hydroxylase activity and loss of immunoreactive 21-hydroxylase protein. Clinical presentations of the patient as the severe salt-wasting form of 21-OHD are in good agreement with these results of the expression study. In conclusion, the patient is a homozygote for the novel intronic IVS9-9C>A mutation, which affects messenger RNA splicing and totally inactivates 21-hydroxylase to give rise to clinically manifest classic salt-wasting 21-OHD.

    Moyamoya disease is a cerebrovascular occlusive disease characterized by progressive stenosis or by occlusion at the terminal portion of the bilateral internal carotid arteries. The unusual vascular network (moyamoya vessels) at the base of the brain with this disease as collateral channels is developed in this disease. Social independence because of cognitive impairment has recently been recognized as an important unsolved social issue with adult moyamoya disease. The patients with cognitive impairment have difficulty in proving their status because the standard neuroradiological and neuropsychological methods to define cognitive impairment with moyamoya disease are not determined. These patients with cognitive impairment should be supported by social welfare as psychologically handicapped persons. Thus Cognitive Dysfunction Survey of the Japanese Patients with Moyamoya Disease (COSMO-JAPAN study) is planned. In this study, we want to establish a standard finding of the cognitive impairment in patients with moyamoya disease.

    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.

    Spastic paraplegia (SPG) type 28 is an autosomal recessive SPG caused by mutations in the DDHD1 gene. We examined a Japanese 54-years-old male patient with autosomal recessive SPG. His parents were consanguineous. He needed a wheelchair for transfer due to spastic paraplegia. There was a history of operations for bilateral hallux valgus, thoracic ossification of the yellow ligament, bilateral carpal tunnel syndrome, bilateral ankle contracture, and lumbar spinal canal stenosis. He noticed gait disturbance at age 14. He used a cane for walking in his 40s. On neurological examination, he showed hyperreflexia, spasticity, and weakness in the lower extremities and bilateral Babinski reflexes. Urinary dysfunctions and impaired vibration sense in the lower limbs were observed. By exome sequencing analysis using Agilent SureSelect and Illumina MiSeq, we identified 17,248 homozygous nucleotide variants in the patient. Through the examination of 48 candidate genes known to be responsible for autosomal recessive SPG, we identified a novel homozygous 4-bp deletion, c.914_917delGTAA, p.Ser305Ilefs*2 in exon2 of the DDHD1 gene encoding phosphatidic acid-preferring phospholipase A1 (PA-PLA1). The mutation is expected to cause a frameshift generating a premature stop codon 3-bp downstream from the deletion. In consequence, the DDHD domain that is known to be critical for PLA1 activity is completely depleted in the mutated DDHD1 protein, predicted to be a functionally null mutation of the DDHD1 gene. By Sanger sequencing, we confirmed that both parents are heterozygous for the mutation. This variation was not detected in 474 Japanese control subjects as well as the data of the 1,000G Project. We conclude that the novel mutation in DDHD1 is the causative variant for the SPG28 patient that is the first record of the disease in Japanese population. PMID:27216551

    A recent multicenter registry study of venous thromboembolism (VTE) patients in Japan demonstrated a high prevalence of inferior vena cava (IVC) filter placement. However, data regarding indications, applications, and outcomes of IVC filters in Japanese patients are quite limited. This study was an observational, single-center, retrospective cohort study of all consecutive patients with acute VTE treated between March 2006 and February 2014. Data extracted included patient demographics, indications, applications, and complications of IVC filters, as well as VTE recurrence and death. A total of 257 consecutive patients were analyzed. Seventy-eight patients (30 %) received IVC filters. The proportions of IVC filter placement were 26 % for deep-vein thrombosis (DVT) alone, 10 % for pulmonary embolism (PE) alone, and 46 % for both DVT and PE. There was no significant difference in patient demographics between the IVC filter group and no-IVC filter group. Stated indications for filter placement were 24 cases (30 %) of DVT in intrapelvic veins, 16 cases (20 %) of DVT in proximal veins, and 11 cases (14 %) of contraindication to anticoagulant therapy. In the IVC filter group, cases of class I indication (guidelines: JCS 75:1258-1281, 2009) numbered only 6 (8 %). Many of the retrievable IVC filters were not removed and placed permanently and the retrieval rate was 42 %. We found complications of IVC filters in 8 cases (10 %). IVC filter placement was significantly associated with a better survival rate and a higher incidence of DVT recurrence during a mean observation period of 541 days. Our research suggests the frequent use of IVC filters for VTE treatment, combined with a low retrieval rate. Most of the stated indications of IVC filter placement for VTE in Japanese patients were cases of DVT in intrapelvic veins or proximal veins, not cases of contraindication to anticoagulant therapy.

    Objective The purpose of this study was to measure serum 25-hydroxyvitamin D [25(OH)D] levels in Japanese patients with diabetic nephropathy and determine the relationship between 25(OH)D concentrations and various factors. Methods The study subjects included 442 patients with type 2 diabetes. Their serum levels of creatinine, HbA1c, intact-parathyroid hormone, urinary albumin, 25(OH)D, and 1,25-dihydroxyvitamin D [1,25(OH)2D] were measured and their estimated glomerular filtration rate (eGFR) was determined. The patients were divided into four groups based on the risk for progression to chronic kidney disease (CKD): low, moderate, high, very high, based on their eGFR and their level of albuminuria. Results The median 25(OH)D level was 14.6 ng/mL; 11% of the patients had 25(OH)D deficiency (<10 ng/mL), and 2% of patients had active vitamin D deficiency, as defined by a 1,25(OH)2D level of <22 pg/mL. The serum 25(OH)D level was correlated with the serum 1,25(OH)2D level in patients with a very high risk for CKD, but not in those with a moderate or high risk for CKD. Conclusion Although the vitamin D levels of the Japanese patients with diabetic nephropathy and CKD were low, the prevalence of vitamin D deficiency, as defined by the 1,25(OH)2D level, was low. Albuminuria, younger age, and female gender were associated with a low 25(OH)D level. The serum level of 25(OH)D should be monitored to assess the vitamin D status of patients with nephropathy and CKD. PMID:27629947

    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).

    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.

    The present study assessed problems in Japanese prisoners (inmates) who abused methamphetamine. Fifty-two male inmates were assessed in 2005-2007 using the Addiction Severity Index-Japanese version and compared with 55 male methamphetamine abusers in hospitals and recovery centers. The chi(2) and Mann-Whitney-Wilcoxon tests showed that the inmates had a significantly lower education level, more frequently had full-time jobs, had more experience living with a sexual partner, and more frequently had a history of juvenile delinquency and criminal records than patients. Although psychiatric symptoms, such as depression, anxiety, and hallucinations, were not common among inmates, suicidal behavior and trouble controlling violence were common in both groups.

    Background: Based on the revised AHA/ACC guidelines, it might be necessary to take into consideration the average life expectancy of Japanese people and revise the Japanese guidelines accordingly. Accordingly, we performed the present study to compare the long-term outcome in patients aged 65 years or older who underwent prosthetic valve replacement at our hospital using mechanical valves or biological valves. Methods: We have performed valve replacement in 416 patients aged 65 years or older (mechanical: 157; biological: 244). Results: There was no significant difference between the mechanical and biological valve for the actuarial survival rate. As for the valve-related complication free rate, in the mechanical valve group, the rates were significantly higher for all patients, aortic valve replacement (AVR) patients, and mitral valve replacement (MVR) patients. Conclusions: Following revision of the AHA/ACC guidelines for selection of prosthetic valves, it is necessary to investigate whether patients aged 60–70 represent the gray zone for selecting valves as in US and European guidelines, or whether a higher age is more appropriate in view of the longer average life expectancy in Japan. Accordingly, further evaluation of the long-term outcome for mechanical and biological valves in Japanese patients is needed to obtain evidence for preparation of original Japanese guidelines on prosthetic valve selection.

    Morning blood pressure (BP) surge is reported as a risk factor for cardiovascular events and end-organ damage independent of the 24-h BP level. Controlling morning BP surge is therefore important to help prevent onset of cardiovascular disease. We compared the efficacy of azilsartan and candesartan in controlling morning systolic BP (SBP) surges by analyzing relevant ambulatory BP monitoring data in patients with/without baseline BP surges. As part of a 16-week randomized, double-blind study of azilsartan (20–40 mg once daily) and candesartan (8–12 mg once daily) in Japanese patients with essential hypertension, an exploratory analysis was carried out using ambulatory BP monitoring at baseline and week 14. The effects of study drugs on morning BP surges, including sleep trough surge (early morning SBP minus the lowest night-time SBP) and prewaking surge (early morning SBP minus SBP before awakening), were evaluated. Patients with sleep trough surge of at least 35 mmHg were defined by the presence of a morning BP surge (the ‘surge group’). Sleep trough surge and prewaking surge data were available at both baseline and week 14 in 548 patients, 147 of whom (azilsartan 76; candesartan 71) had a baseline morning BP surge. In surge group patients, azilsartan significantly reduced both the sleep trough surge and the prewaking surge at week 14 compared with candesartan (least squares means of the between-group differences −5.8 mmHg, P=0.0395; and −5.7 mmHg, P=0.0228, respectively). Once-daily azilsartan improved sleep trough surge and prewaking surge to a greater extent than candesartan in Japanese patients with grade I–II essential hypertension. PMID:24710336

    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

    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

    This phase I study in Japanese patients evaluated the safety, pharmacokinetics, and preliminary efficacy of palbociclib, a highly selective and reversible oral cyclin-dependent kinase 4/6 inhibitor, as monotherapy for solid tumors (part 1) and combined with letrozole as first-line treatment of postmenopausal patients with estrogen receptor-positive, human epidermal growth factor receptor 2-negative advanced breast cancer (part 2). Part 1 evaluated palbociclib 100 and 125 mg once daily (3 weeks on/1 week off; n = 6 each group) to determine the maximum tolerated dose. Part 2 evaluated palbociclib maximum tolerated dose (125 mg) plus letrozole 2.5 mg (n = 6). The most common treatment-related adverse event was neutropenia (all grades/grade 3/4): 100 mg, 83%/67%; 125 mg, 67%/33%; and palbociclib plus letrozole, 100%/83%. Heavier pretreatment with chemotherapy may have resulted in higher neutropenia rates observed with the 100-mg dose. Palbociclib exposure was higher with 125 vs 100 mg (mean area under the plasma concentration-time curve over dosing interval [τ]: 1322 vs 547.5 ng·h/mL [single dose], 2838 vs 1276 ng·h/mL [multiple dose]; mean maximum plasma concentration: 104.1 vs 41.4 ng/mL [single dose], 185.5 vs 77.4 ng/mL [multiple dose]). Half-life was 23-26 h. No drug-drug interactions between palbociclib and letrozole occurred. Four patients had stable disease (≥24 weeks in one patient with rectal cancer [100 mg] and one with esophageal cancer [125 mg]) in part 1; two patients had partial response and two had stable disease (both ≥24 weeks) in part 2. Palbociclib at the 125-mg dose (schedule 3/1) was tolerated and is the recommended dose for monotherapy and letrozole combination therapy in Japanese patients. The trials are registered with www.ClinicalTrials.gov: A5481010 and NCT01684215.

    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

    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

    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.

    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.

    Background: Many Japanese patients with hepatic disorders confirmed on diagnostic imaging and coexisting upper gastrointestinal (GI) peptic lesions receive treatment with proton pump inhibitors. Some pharmacotherapies used to treat peptic ulcers have been associated with adverse drug reactions (ADRs), including elevated liver enzyme levels. Objective: The aim of this study was to determine the tolerability and effectiveness of rabeprazole sodium in treating peptic lesions in patients with coexisting hepatic disorders. Methods: This open-label, practice-based, postmarketing surveillance investigation was conducted at 15 centers across Japan. Male and female patients aged ≥18 years with peptic lesions confirmed on upper GI endoscopy and with underlying hepatic disease were enrolled. Patients were randomly assigned to receive rabeprazole 10 or 20 mg PO (tablet) QD after a meal for up to 8 weeks. Tolerability was assessed using monitoring of the incidence of ADRs determined by direct patient questioning, spontaneous reporting, and laboratory assessment. All patients who received at least 1 dose of study drug were included in the tolerability assessment. Effectiveness was assessed at baseline and study end using the rates of achievement of improvement on endoscopy, relief of subjective/objective symptoms (rates of improvement in epigastric pain and heartburn), and global improvement. The effectiveness analysis included all patients with complete data before and after treatment. Subanalyses were conducted to determine the effectiveness of drug by identification of the proportion of patients with coexisting hepatic disorders (cirrhosis, chronic hepatitis, and other hepatic diseases [eg, alcoholic hepatitis, fatty liver]) and by peptic lesion (gastric ulcer, duodenal ulcer, stomal ulcer, and reflux esophagitis) who achieved improvement. Results: A total of 114 patients were enrolled; 108 patients were included in the tolerability analysis (81 men, 27 women; mean age, 59

    This postmarketing surveillance study assessed the safety and effectiveness of daily teriparatide treatment in patients with osteoporosis in a Japanese clinical setting. In this prospective, multicenter, observational study, patients with osteoporosis at high risk for fracture received subcutaneous injections of teriparatide (20 μg/day) for a maximum of 24 months. For this interim report, data from 1,671 patients were eligible for analysis at the cutoff date. The mean age was 75.3 years; 93% of patients (1,552/1,671 patients) were women. There were 117 adverse drug reactions (ADRs) reported in 101 of 1,671 patients (6.04%); the most common reported ADRs were nausea, dizziness, headache, and palpitations. No clinically significant safety issues were identified, although 5 serious ADRs were reported in 4/1,671 (0.24 %) patients. At 12 months, 71.9% of patients remained on teriparatide treatment. From 1 month, there were rapid increases in the biomarkers of bone formation P1NP and, to a lesser extent, BAP. In contrast, increases in the biomarkers of bone resorption, serum NTX, urinary NTX, and TRACP5b, were smaller. After 12 months of treatment, there was an increase in bone mineral density at the lumbar spine, femoral neck, and total hip, and a decrease in the Visual Analog Scale score for back pain. The incidence of new vertebral and nonvertebral fractures was 1.21% and 3.18%, respectively. In conclusion, the favorable safety profile and effectiveness of teriparatide observed in this population of Japanese patients with osteoporosis were accompanied by relatively high persistence with treatment, which is a key factor in the success of osteoporosis treatment.

    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.

    Purpose To investigate the efficacy of targeted exome sequencing for mutational screening of Japanese patients with cone dystrophy (CD) or cone-rod dystrophy (CRD). Methods DNA samples from 43 Japanese patients with CD or CRD were sequenced using an exome-sequencing panel targeting all 193 known inherited eye disease genes and next-generation sequencing methodologies. Subsequently, candidate variants were screened using systematic data analyses, and their potential pathogenicity was assessed using distinct filtering approaches, which included the frequency of the variants in normal populations, in silico prediction tools, and cosegregation. Results Causative mutations were detected in 12 patients with CD or CRD (27.9%). In total, 14 distinct mutations were identified in the genes ABCA4, CDHR1, CRB1, CRX, GUCY2D, KCNV2, PROM1, PRPH2, and RDH5, including four novel mutations, c.3050+1G>A in ABCA4, c.386A>G in CDHR1, c.652+1_652+4del in CRB1, and c.454G>A in KCNV2. Moreover, a putative pathogenic mutation was identified in RGS9BP, a gene recognized as the source of bradyopsia. Conclusions Targeted exome sequencing effectively identified causative mutations in Japanese patients with CD or CRD. The results confirmed the heterogeneity of the genes responsible for CD and CRD in Japanese populations, as well as the efficacy of targeted exome sequencing-based screening of patients with inherited retinal degeneration.

    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

    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.

    Background/Aims Few studies are available that have investigated the risk factors for overlapping irritable bowel syndrome (IBS)-like symptoms in patients with inactive inflammatory bowel disease (IBD). The present study has 3 objectives: (1) to assess the prevalence of IBS-like symptoms in Japanese patients with inactive IBD using Rome III criteria, (2) to examine the relationship of IBS-like symptoms to health related quality of life (HR-QOL), and (3) to investigate associations for developing IBS-like symptoms in patients with inactive IBD. Methods IBS-like symptoms were evaluated using the Rome III questionnaire for functional gastrointestinal disorders. HR-QOL and hospital anxiety and depression scale were evaluated. Results IBS-like symptoms were found in 17.5% (7/40) of patients with inactive ulcerative colitis, 27.1% (29/107) of patients with inactive Crohn’s disease (CD), and 5.3% (23/438) of healthy control subjects. The QOL level was significantly lower and anxiety score was significantly higher in inactive CD patients with IBS-like symptoms than in those without such symptoms (P = 0.003, P = 0.009). Use of anti-anxiety drugs was associated with the presence of IBS symptoms (P = 0.045). HR-QOL score was lower and anxiety score was higher in patients with inactive ulcerative colitis, but the difference was not statistically significant. Conclusions The prevalence of IBS-like symptoms in inactive IBD patients was significantly higher than in healthy controls. Inactive CD patients with IBS-like symptoms has low QOL and anxiety; suggesting that anxiety may be associated with symptom development in such patients. PMID:27193973

    The use of endocrine therapy in breast cancer represents one of the earliest molecular targeting strategies used in cancer treatment. Tamoxifen, a selective estrogen-receptor (ER) modulator, has been the standard of care for women with receptor-positive breast cancer for the last 30 years. Tamoxifen suppresses the estrogen-dependent growth of breast cancer cells by specifically targeting the ER. Because of estrogenic effects, tamoxifen does not increase the risk of osteoporosis, but it can lead to endometrial cancer and thromboembolism. The third-generation aromatase inhibitors (AIs) exert their tumor antiproliferative action by targeting an enzyme critical for estrogen biosynthesis. The AIs thus have a different mechanism of action than tamoxifen, and a different safety profile. The majority of adverse events (AEs) related to the AIs are mild to moderate. Most of these AEs are common to menopause and are predictable and manageable. This review looks at AI-associated side effects and current clinical management strategies, with a particular emphasis on managing bone health. Compliance with long-term therapy, strategies to improve adherence, and considerations in elderly patients with hormone-responsive breast cancer are also discussed.

    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.

    Blood pressure (BP) control throughout the entire day is recommended for cardiovascular protection. Angiotensin-II receptor blockers (ARBs) are widely used in hypertensive patients because of beneficial class effects. It is uncertain, however, whether are there any differences in 24-h BP profiles among ARBs. We examined ambulatory blood pressure monitoring (ABPM) among 211 Japanese hypertensive patients (age, 69.4 ± 9.6 years; female, 59.2%) under treatment with five different ARBs. Patients were divided into five groups according to ARBs prescribed. Patient backgrounds were almost identical in all the groups and there were no differences in office, 24-h and daytime BP; however, nighttime BP with olmesartan was significantly lower than with other ARBs. Office BPs with candesartan and telmisartan, but not other ARBs, correlated well with 24-h BP (p < 0.01). Also, there were higher correlations between daytime and nighttime BP with candesartan and telmisartan. In all patients, pulse pressure with office BP was significantly correlated with ambulatory arterial stiffness index (p = 0.001) and fluctuation of systolic BP on ABPM (p = 0.002). In conclusion, different ARB treatments produced meaningful differences in 24-h profiles.

    The efficacy and safety of the long-acting repeatable formulation of octreotide (OCT-LAR) treatment in patients suffering from acromegaly was investigated retrospectively in Shizuoka prefecture, Japan. Thirty patients (11 male, 19 female; average age, 48.9 years old), 29 of whom had undergone transsphenoidal surgery previously, were treated with OCT-LAR. OCT-LAR was injected i.m. every 4 weeks with an intended protocol of 20 mg over 24 months, however, 46.7% of patients required the dose of OCT-LAR to be increased. The final average dose of OCT-LAR was 25.0 +/- 6.8 mg. Administering OCT-LAR significantly decreased serum GH and insulin-like growth factor 1 (IGF-1) levels (from 13.7 +/- 11.9 to 5.8 +/- 7.3 microg/L and from 585 +/- 263 to 339 +/- 193.7 microg/L after 3 months, respectively). Among patients treated with OCT-LAR, 56.7% expressed patients when the rate of GH patient but it was uncertain whether OCT-LAR was involved in its development because the patient was not examined before OCT-LAR treatment. There were no abnormalities on liver function tests in any patients. In conclusion, our results showed that OCT-LAR was safe and effective as a therapeutic option for Japanese patients with acromegaly in a postoperative setting, by controlling the disease activity.

    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

    An increasing amount of clinical research is being conducted to test the efficacy and effectiveness of new medications, therapies, and medical procedures. These studies often require that patients be invited to be subjects. However, what do patients really understand whenever they are asked to participate in clinical research? Are patients aware that research is clearly different from treatment? Are they aware that their participation in research is to benefit future patients? Despite the desire of clinical agencies to support research, there is the concern about how they can best protect the rights of patients who are subjects in this research. The author briefly discusses clinical research, patients as vulnerable subjects, the therapeutic misconception, and informed consent. In addition, recommendations are provided to help assure that the rights of patients who are research subjects are protected.

    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

    Use of prescription opioids for cancer pain according to the World Health Organization analgesic ladder has been accepted in Japan. Although oxycodone and fentanyl are commonly used as first-line analgesics, a few clinical reports have been published on interindividual variations in their pharmacokinetics and clinical responses in cancer patients. (1) Some factors relating to CYP2D6, CYP3A, ATP-binding cassette sub-family B member 1 (ABCB1), and opioid receptor mu 1 (OPRM1) involve oxycodone pharmacokinetics and sensitivity in humans. The relations between their genetic variations and clinical responses to oxycodone are being revealed in limited groups. In our study, the impact of genetic variants and pharmacokinetics on clinical responses to oxycodone were evaluated in Japanese populations. (2) Opioid switching improves the opioid tolerance related to the balance between analgesia and adverse effects. Some patients have difficulty in obtaining better opioid tolerance in recommended conversion ratios. The activities of CYP3A, ABCB1, and OPRM1 contribute to the interindividual variations in clinical responses to fentanyl in cancer patients. However, the variations in opioid switching remain to be clarified in clinical settings. In our study, genetic factors related to interindividual variations in clinical responses in opioid switching to fentanyl were revealed in Japanese populations. In this symposium review, the possibility of approaches to personalized palliative care using opioids based on genetic variants of CYP2D6, CYP3A5, ABCB1, and OPRM1 is discussed.

    2013-01-01

    Background Genetic tests for hereditary hearing loss inform clinical management of patients and can provide the first step in the development of therapeutics. However, comprehensive genetic tests for deafness genes by Sanger sequencing is extremely expensive and time-consuming. Next-generation sequencing (NGS) technology is advantageous for genetic diagnosis of heterogeneous diseases that involve numerous causative genes. Methods Genomic DNA samples from 58 subjects with hearing loss from 15 unrelated Japanese families were subjected to NGS to identify the genetic causes of hearing loss. Subjects did not have pathogenic GJB2 mutations (the gene most often associated with inherited hearing loss), mitochondrial m.1555A>G or 3243A>G mutations, enlarged vestibular aqueduct, or auditory neuropathy. Clinical features of subjects were obtained from medical records. Genomic DNA was subjected to a custom-designed SureSelect Target Enrichment System to capture coding exons and proximal flanking intronic sequences of 84 genes responsible for nonsyndromic or syndromic hearing loss, and DNA was sequenced by Illumina GAIIx (paired-end read). The sequences were mapped and quality-checked using the programs BWA, Novoalign, Picard, and GATK, and analyzed by Avadis NGS. Results Candidate genes were identified in 7 of the 15 families. These genes were ACTG1, DFNA5, POU4F3, SLC26A5, SIX1, MYO7A, CDH23, PCDH15, and USH2A, suggesting that a variety of genes underlie early-childhood hearing loss in Japanese patients. Mutations in Usher syndrome-related genes were detected in three families, including one double heterozygous mutation of CDH23 and PCDH15. Conclusion Targeted NGS analysis revealed a diverse spectrum of rare deafness genes in Japanese subjects and underscores implications for efficient genetic testing. PMID:24164807

    Ruxolitinib is a potent Janus kinase (JAK) 1/JAK2 inhibitor that has demonstrated rapid and durable improvements in splenomegaly and symptoms and a survival benefit in 2 phase 3 trials in patients with myelofibrosis. Ruxolitinib was well tolerated and effectively reduced splenomegaly and symptom burden in Asian patients with myelofibrosis in the Asian multinational, phase 2 Study A2202. We present a subset analysis of Japanese patients (n = 30) in Study A2202. At data cutoff, 22 patients were ongoing; 8 discontinued, mainly due to adverse events (n = 4). At week 24, 33 % of patients achieved ≥35 % reduction from baseline in spleen volume; 56.0 % achieved ≥50 % reduction from baseline in total symptom score, as measured by the 7-day Myelofibrosis Symptom Assessment Form v2.0. The most common adverse events were anemia (63 %), thrombocytopenia (40 %), nasopharyngitis (37 %), decreased platelet counts (30 %), and diarrhea (30 %). Dose reductions or interruptions due to hemoglobin decreases were more frequent in Japanese patients; no loss of efficacy and no discontinuations due to hematologic abnormalities were observed. Ruxolitinib was well tolerated in Japanese patients and provided substantial reductions in splenomegaly and myelofibrosis-related symptoms similar to those observed in the overall Asian population and phase 3 COMFORT studies.

    Advanced glycation end products (AGE) are significantly increased in end-stage renal disease patients and it has been suggested that AGE accumulation is related to the progression of cardiovascular disease. An autofluorescence reader non-invasively assesses AGE accumulation using skin autofluorescence under ultraviolet light. Skin autofluorescence has been reported to be an independent predictor of mortality in Caucasian hemodialysis patients. The aim of this study was to assess whether skin autofluorescence in Japanese hemodialysis patients is related to the presence of cardiovascular disease. In this cross-sectional study, patients on maintenance hemodialysis (N = 128; 59 men, 69 women) were included. AGE accumulation was assessed by skin autofluorescence using an autofluorescence reader. Associations between skin autofluorescence, cardiovascular disease, and other parameters were studied. Skin autofluorescence correlated with age (r = 0.32, P < 0.01), diabetes (r = 0.21, P = 0.02), carotid intima-media thickness (IMT) (r = 0.23, P = 0.02), high-sensitivity C-reactive protein (hsCRP) (r = 0.20, P = 0.03), and plasma pentosidine (r = 0.20, P = 0.03). Each parameter was compared in patients with and without cardiovascular disease; the gender distribution, age, carotid IMT, high-density lipoprotein cholesterol, hsCRP, and skin autofluorescence were significantly related to the presence of cardiovascular disease. Multiple logistic regression analysis identified carotid IMT (OR 6.76), hsCRP (OR 1.41), and skin autofluorescence (OR 2.29) as significant factors for the presence of cardiovascular disease. Increased skin autofluorescence was related to the presence of cardiovascular disease in Asian (non-Caucasian) hemodialysis patients, and therefore an autofluorescence reader might have the potential to be a useful assessment of cardiovascular risk in these patients.

    We report a Japanese family with adrenoleukodystrophy (ALD) with a three base pair deletion (delGAG 291) in the ALD gene. A variety of phenotypes were observed within this family. While the proband (patient 1) was classified as having a rare intermediate type of adult cerebral and cerebello-brain stem forms, his younger brother (patient 2) and nephew (patient 3) had a childhood ALD type. Another nephew (patient 4) of patient 1 was classified as having an adolescent form. The tau level in the cerebrospinal fluid (CSF) in patient 1 was as high as that of patients with Alzheimer's disease (AD). His brain magnetic resonance image (MRI) showed abnormalities in the bilateral cerebellar hemispheres and brain stem, but not in the cerebral white matter, where marked reductions of the cerebral blood flow and oxygen metabolism were clearly demonstrated by positron emission tomography (PET). In patients 2 and 3, the autopsy findings showed massive demyelination of the cerebral white matter with sparing of the U-fibers, compatible with the findings of childhood ALD. Oleic and erucic acids (Lorenzo's Oil) were administered to patients 1 and 4, but sufficient effectiveness was not obtained. The findings in this family suggest that delGAG291 is part of the cause of Japanese ALD with phenotypic variations. Moreover, although the scale of the study is limited, there is a possibility that PET can detect an insidious lesion which is undetectable by computed tomogram (CT) or MRI analysis, and that the higher level of tau reflects the process of neuronal degeneration in ALD. Lorenzo's Oil should be given in the early stage.

    We have recently used Q-switched alexandrite laser for the treatment of various kinds of pigmented skin lesions. We retrospectively compared therapeutic outcomes of 153 Japanese patients who consulted our department. This approach was not very efficient for nevus spilus/café-au-lait spots, which seemed laser-resistant, especially when the pigmentation had appeared after 1 year of age, was treated after 5 years of age, was located on the face, was oval with a smooth border, and the patient was male. This approach was equally effective for senile lentigo, nevus of Ota, and Mongolian spots, but less effective for acquired bilateral nevus of Ota-like macules. Some patients with sacral Mongolian spots or those with light-colored, senile lentigo developed severe post-inflammatory hyperpigmentation after treatment. As a whole, good therapeutic outcome was achieved after multiple treatment sessions. However, the use of other lasers or other treatment modalities should be considered to treat nevus spilus/café-au-lait spots.

    Cowden's disease (CD) is an autosomal dominant disorder which confers a high susceptibility to diverse benign and malignant tumors. The PTEN (phosphatase and tensin homologue deleted in chromosome ten) gene has been identified as a tumor suppressor gene responsible for cancers of the endometrium, ovary, prostate, and glioblastomas. Recently, germline mutations of this gene were also found in patients with CD, and it is now recognized as a gene responsible for this disease. We identified a germline nonsense mutation at codon 130 in exon 5 of PTEN in a 56-year-old Japanese woman with CD. The patient had adenoid facies and mucocutaneous lesions including multiple facial papules, acral keratoses on neck and shoulders, palmoplantar keratoses, multiple oral papillomas, scrotal tongue, mucosal and cutaneous hemangiomas, and a sclerotic fibroma on the arm. She also had benign and malignant polypoid neoplasms throughout the entire digestive tract, including adenocarcinoma of the colon and submucosal lipomas of the rectum, as well as bilateral breast carcinomas, multinodular goiters, an ovarian cyst with a fibroma-like nodule, hepatic hemangiomas, and abdominal hernia. We searched CD cases with the same genotypic PTEN mutation as the present case and compared their phenotypes. Further studies will disclose a better understanding of the role of mutation in the PTEN gene in the course of tumorigenesis of both benign and malignant tumors developed in patients with CD.

    Summary 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

    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

    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

  13. TNF-α promoter polymorphism: a factor contributing to the different immunological and clinical phenotypes in Japanese encephalitis

    2012-01-01

    Background More than three billion populations are living under the threat of Japanese encephalitis in South East Asian (SEA) countries including India. The pathogenesis of this disease is not clearly understood and is probably attributed to genomic variations in viral strains as well as the host genetic makeup. The present study is to determine the role of polymorphism of TNF-alpha promoter regions at positions -238G/A, -308G/A, -857C/T and -863C/A in the severity of Japanese encephalitis patients. Methods Total of 142 patients including 66 encephalitis case (IgM/RT-PCR positive), 16 fever cases (IgM positive) without encephalitis and 60 apparently healthy individuals (IgG positive) were included in the study. Polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) using site specific restriction enzymes were implemented for polymorphism study of TNF alpha promoter. Results Following the analysis of the digestion patterns of four polymorphic sites of the TNF- alpha promoter region, a significant association was observed between the allele -308A and -863C with the patients of Japanese encephalitis. Conclusions TNF- alpha 308 G/A has been shown to be associated with elevated TNF- alpha transcriptional activity. On the other hand, polymorphism at position -863C/A in the promoter region has been reported to be associated with reduced TNF- alpha promoter activity and lower plasma TNF levels. As per the literature search, this is the first study to identify the role of TNF- alpha promoter in JE infection. Our results show that subjects with - 308A and -863C alleles are more vulnerable to the severe form of JE infection. PMID:22276993

    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

    Purpose To investigate whether the GLC1F locus is associated with normal tension glaucoma (NTG) in Japanese patients. Methods We recruited 242 unrelated Japanese subjects, including, 141 NTG patients and 101 healthy controls. The patients exhibiting a comparatively early onset were selected as they suggest that genetic factors may show stronger involvement. Genotyping and assessment of allelic diversity was performed on 11 highly polymorphic microsatellite markers in and around the GLC1F locus. Results Individuals carrying the 163 allele of D7S1277i had a statistically significant increased risk of NTG (p=0.0013, pc=0.016, OR=2.47, 95%CI=1.42–4.30). None of the other markers identified significant loci (pc>0.05) after Bonferroni’s correction. Conclusions These findings suggested that the genes in the GLC1F locus may be associated with the pathogenesis of NTG. PMID:20309402

    2012-01-01

    Background Kampo medicines are traditional Japanese medicines produced from medicinal plants and herbs. Even though the efficacy of Kampo medicines for controlling cancer-related symptoms is being reported, their actual nationwide clinical use has not been comprehensively investigated. We aimed to investigate physicians’ recognition of Kampo medicines and their clinical use for cancer patients in the field of palliative care. Methods A cross-sectional self-administered anonymous questionnaire was distributed to 549 physicians working in palliative care teams at 388 core cancer treatment hospitals and 161 certified medical institutions that have palliative care units (PCUs). Results Valid responses were obtained from 311 physicians (response rate, 56.7%) who were evenly distributed throughout the country without significant geographical biases. Kampo medicines were prescribed for controlling cancer-related symptoms by 64.3% of the physicians. The symptoms treated with Kampo medicines were numbness/hypoesthesia (n = 99, 49.5%), constipation (n = 76, 38.0%), anorexia/weight loss (n = 72, 36%), muscle cramps (n = 71, 35.5%) and languor/fatigue (n = 64, 32.0%). Regarding open issues about prescription, 60.7% (n = 173) of the physicians raised the issue that the dosage forms need to be better devised. Conclusions To increase the clinical use of Kampo medicines, more evidence from clinical studies is necessary. In addition, their mechanisms of action should be clarified through laboratory studies.

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

    Endogenous Cushing's syndrome is an endocrine disease resulting from chronic exposure to excessive glucocorticoids produced in the adrenal cortex. Although the ultimate outcome remains uncertain, functional and morphological brain changes are not uncommon in patients with this syndrome, and generally persist even after resolution of hypercortisolemia. We present an adolescent patient with Cushing's syndrome who exhibited cognitive impairment with brain atrophy. A 19-year-old Japanese male visited a local hospital following 5 days of behavioral abnormalities, such as money wasting or nighttime wandering. He had hypertension and a 1-year history of a rounded face. Magnetic resonance imaging (MRI) revealed apparently diffuse brain atrophy. Because of high random plasma cortisol levels (28.7 μg/dL) at 10 AM, he was referred to our hospital in August 2011. Endocrinological testing showed adrenocorticotropic hormone-independent hypercortisolemia, and abdominal computed tomography demonstrated a 2.7 cm tumor in the left adrenal gland. The patient underwent left adrenalectomy in September 2011, and the diagnosis of cortisol-secreting adenoma was confirmed histologically. His hypertension and Cushingoid features regressed. Behavioral abnormalities were no longer observed, and he was classified as cured of his cognitive disturbance caused by Cushing's syndrome in February 2012. MRI performed 8 months after surgery revealed reversal of brain atrophy, and his subsequent course has been uneventful. In summary, the young age at onset and the short duration of Cushing's syndrome probably contributed to the rapid recovery of both cognitive dysfunction and brain atrophy in our patient. Cushing's syndrome should be considered as a possible etiological factor in patients with cognitive impairment and brain atrophy that is atypical for their age.

    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

    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

    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

  4. Detection of Merkel cell polyomavirus in cervical squamous cell carcinomas and adenocarcinomas from Japanese patients

    PubMed Central

    2012-01-01

    Background Merkel cell polyomavirus (MCPyV) was identified originally in Merkel cell carcinoma (MCC), a rare form of human skin neuroendocrine carcinoma. Evidence of MCPyV existence in other forms of malignancy such as cutaneous squamous cell carcinomas (SCCs) is growing. Cervical cancers became the focus of our interest in searching for potentially MCPyV-related tumors because: (i) the major histological type of cervical cancer is the SCC; (ii) the uterine cervix is a common site of neuroendocrine carcinomas histologically similar to MCCs; and (iii) MCPyV might be transmitted during sexual interaction as demonstrated for human papillomavirus (HPV). In this study, we aimed to clarify the possible presence of MCPyV in cervical SCCs from Japanese patients. Cervical adenocarcinomas (ACs) were also studied. Results Formalin-fixed paraffin-embedded tissue samples from 48 cervical SCCs and 16 cervical ACs were examined for the presence of the MCPyV genome by polymerase chain reaction (PCR) and sequencing analyses. PCR analysis revealed that 9/48 cervical SCCs (19%) and 4/16 cervical ACs (25%) were positive for MCPyV DNA. MCPyV-specific PCR products were sequenced to compare them with reference sequences. The nucleotide sequences in the MCPyV large T (LT)-sequenced region were the same among MCPyV-positive cervical SCCs and AC. Conversely, in the MCPyV viral protein 1 (VP1)-sequenced region, two cervical SCCs and three cervical ACs showed several nucleotide substitutions, of which three caused amino acid substitutions. These sequencing results suggested that three MCPyV variants of the VP1 were identified in our cases. Immunohistochemistry showed that the LT antigen was expressed in tumor cells in MCPyV-positive samples. Genotyping of human HPV in the MCPyV-positive samples revealed that infected HPVs were HPV types 16, 31 and 58 for SCCs and HPV types 16 and 18 for ACs. Conclusions This study provides the first observation that MCPyV coexists in a subset of HPV

    We evaluated the efficacy and tolerability of Hachimi-jio-gan (HJG; bā wèi dì huáng wán) and Gosha-jinki-gan (GJG; jì shēng shèn qì wán), two traditional Japanese medicines, in 60 patients with lower urinary tract symptoms (LUTS) having cold sensitivity unresponsive to α1-blockers or antimuscarinic drugs. 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 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.

    Objectives: The aim of this study is examine the reliability and validity of the patient classification which is based on clinical data with comparing to nurse’s check Method: Nurse Experts estimated the content validity of extracting KPCS-1(Korea patient classification system for nurses Version 1) activities score from clinical data in storage of AMIS (Asan Medical Center information system). After verifying the content validity of extraction method from clinical data, two methods extracting KPCS-1 score (from clinical data vs. nurses’ recording) were compared for 348 patients. Results: This study demonstrated that extracting patient classification from clinical data is high value of validity (except 4 items excluded from this study), reliability between two methods extracting KPCS-1(from clinical data and nurses’ recording) is high value (ICC=0.96, p<.001) and construct validity of two methods has similarity. Conclusions: It is believed that the patient classification system which is made from only clinical data without nurse’s work burden is available. And 4 items which was excluded on KPCS-1 and examine area which had low level of reliability are needed to be amended. PMID:24199043

    Anti-soluble liver antigen/liver pancreas (SLA/LP) autoantibody has been proposed to be one of the autoantibodies characterizing autoimmune hepatitis (AIH). Recently, one of the autoantigens to anti-SLA/LP was identified as a UGA suppressor tRNA-associated protein. Although the function of this protein remains unknown, the recombinant protein has been prokaryotically expressed. Using this protein as an antigen, a recombinant immunoassay for anti-SLA/LP autoantibody has been established and the frequency and significance of this autoantibody have been discussed in European countries. So, in the present study, we investigated anti-SLA/LP autoantibodies in Japanese patients with autoimmune liver diseases using the recombinant antigen ELISA and Western blot assay. Seventy-five patients with AIH type 1, 5 with AIH type 2, 46 with primary biliary cirrhosis, 10 with primary sclerosing cholangitis, 47 with chronic hepatitis C, 48 with systemic lupus erythematosus, 3 with cryptogenic hepatitis, and 40 normal controls were the subjects of the present study. Anti-SLA/LP autoantibodies were detected in only 5 of 75 (6.7%) patients with AIH type 1, but in none of the other 159 patients or 40 normal controls. The clinicopathologic features of anti-SLA/LP-positive AIH type 1, including carriers of HLA DR locus variations, were not significantly different from anti-SLA/LP-negative patients except for the mortality rate. Anti-SLA/LP autoantibody was detected at a low frequency in Japanese patients with AIH type 1 and did not significantly influence clinical features. However, since it has high disease-specificity to AIH type 1, further analysis of SLA/LP may contribute to help clarify the pathogenesis of AIH type 1.

    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.

    The prevalence of spermatogenic failure (SF) has gradually increased during the past few decades at least in several countries. Although multiple factors would be involved in this phenomenon, one important factor would be excessive estrogen effects via estrogen receptors (ERs). Thus, we performed haplotype analysis of ESR2 encoding ERβ in 125 Japanese SF patients and 119 age-matched control males, using single nucleotide polymorphisms (SNPs) 1-9 that are widely distributed on the ~120-kb genomic sequence of ESR2. Consequently, a linkage disequilibrium (LD) block was detected in an ~60-kb region encompassing SNPs 2-7 in both groups, and four major estimated haplotypes were identified within the LD block. Furthermore, the most prevalent 'TGTAGA' haplotype was found to be significantly associated with SF, with the P-value obtained by the Cochran-Armitage trend test (0.0029) being lower than that obtained by a 100 000-times permutation test (0.0038) to cope with the problem of multiple comparisons. The results, in conjunction with our previous data indicating lack of a susceptibility factor on ESR1 encoding ERα, imply that the specific 'TGTAGA' haplotype of ESR2 raises the susceptibility to the development of SF.

    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.

    Cutaneous plasmacytosis is an uncommon disease characterized by a cutaneous polyclonal plasma cell infiltrate usually associated with polyclonal hypergammaglobulinemia. It has predominantly been found in Japanese patients and it is rare in white patients. Clinically, this condition manifests as multiple red to dark brown skin lesions that mainly are located on the trunk. We report the case of a 66-year-old white woman who presented with reddish brown to violaceous macules and plaques restricted to the extremities. The histopathologic findings, laboratory data, and systemic studies led us to the diagnosis of cutaneous plasmacytosis.

    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

    Charcot-Marie-Tooth disease type 1 (CMT1) is a heterogeneous disorder. Most CMT1 patients are associated with a duplication of 17p11.2-p12 (CMT1A duplication), but a small number of patients have mutations of peripheral myelin protein 22 (PMP22), myelin protein zero (MPZ), connexin 32 (Cx32) and early growth response 2 (EGR2) genes. In our previous study, we identified the responsible mutations in 72 of 128 Japanese CMT1 patients as CMT1A duplication in 40, PMP22 mutation in 6, MPZ mutation in 12 and Cx32 mutation in 14 patients. A total of 56 Japanese CMT1 patients with no identified mutations were screened for EGR2 mutation by denaturing gradient gel electrophoresis (DGGE). We detected a heterozygous Asp383Tyr mutation of EGR2 in one patient with severe CMT1, Dejerine-Sottas syndrome. EGR2 mutation is rare cause of CMT1 in Japan as in other nations. We were unable to identify the responsible mutation in 55 of 128 CMT1 patients and need further analysis to identify their candidate genes. PMID:12736090

    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 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.

    Currently, there is no satisfactory treatment for Raynaud's phenomenon (RP) in systemic sclerosis (SSc). Recently, it has been reported that botulinum toxin A (BTX-A) injection was effective for the treatment of RP in SSc patients. The objective was to assess the efficacy and safety of BTX-A on RP in Japanese SSc patients. In the prospective, case series study, 10 Japanese SSc patients with RP received 10 U of BTX-A injections into the hand. The change in severity of RP, including the frequency of attacks/pain, color changes, duration time of RP and the severity of pain, was assessed by Raynaud's score and pain visual analog scale (VAS) at each visit during 16 weeks. The recovery of skin temperature 20 min after cold water stimulation was examined by thermography at baseline and 4 weeks after injection. The number of digital ulcers (DU) and adverse effects were assessed at each visit. BTX-A injection decreased Raynaud's score and pain VAS from 2 weeks after injection, and the suppressive effect was continued until 16 weeks after injection. Skin temperature recovery after cold water stimulation at 4 weeks after injection was significantly enhanced compared with that before injection. All DU in five patients were healed within 12 weeks after injection. Neither systemic nor local adverse effects were observed in all cases. We conclude that BTX-A injection significantly improved the activity of RP in SSc patients without any adverse events, suggesting that BTX-A may have possible long-term preventive and therapeutic potentials for RP in Japanese SSc patients.

    The aim of this study was to evaluate whether linezolid minimum inhibitory concentration (MIC) creep occurred in Staphylococcus aureus clinical isolates, including methicillin-resistant S. aureus (MRSA), over a recent 5-year period at a single Japanese center. A total of 453 MRSA and 195 methicillin-susceptible S. aureus (MSSA) isolates recovered from inpatients from April 1, 2008 to March 31, 2013 were analyzed. The MIC of linezolid was determined by automated Vitek-2 system. The modal MIC, MIC range, MIC50 and MIC90 (MICs required to inhibit the growth of 50% and 90% of organisms, respectively), geometric mean MIC and percentages of susceptible and resistant isolates were evaluated for each fiscal year. None of the S. aureus isolates were resistant to linezolid. Isolates with an MIC of >1 µg/mL were more common in the MSSA samples than in the MRSA samples (91.3% versus 38.2%, p<0.001). The linezolid geometric mean MIC increased by 0.403 µg/mL (from 1.178 in 2008 to 1.582 in 2012) in the MRSA isolates (p=0.006, r(2)=0.945 according to a linear regression analysis) over the 5-year period; however, no increase was observed in the MSSA isolates. The frequency of MRSA isolates with an MIC of 1 µg/mL decreased (from 76.3% in 2008 to 35.4% in 2012) and the isolates with MICs of >1 µg/mL increased over time (from 23.7% in 2008 to 64.6% in 2012). This report demonstrates the occurrence of linezolid MIC creep, as determined using the geometric mean MIC, in MRSA clinical isolates at a single Japanese center.

    Objective: To investigate the usefulness of D-dimer as a screening method as well as to explore potent predictors of deep vein thrombosis (DVT) in hospitalized Japanese patients with acute medical diseases/episodes. Methods and Subjects: This study was a multi-center, prospective, observational study. The inclusion criteria were hospitalized patients at high risk of developing venous thromboembolism with; (1) congestive heart failure, acute exacerbation of chronic obstructive pulmonary disease, infectious diseases, or inflammatory diseases, (2) bed rest ≥4 days, and (3) ≥60 years old. D-dimer was measured on the same day as ultrasonography. Multivariate logistic regression analysis was performed to investigate predictors associated with the presence of DVT. Results: Sixty-nine patients were enrolled. The prevalence of DVT was 33.3% (23/69; 95% C.I., 19.4% to 47.3%). D-dimer was measured in 42 patients and the sensitivity and negative predictive value reached 100%, while the specificity (13.3%) and positive predictive value (31.6%) were low (cut-off value: 0.9 or 1.0 µg/mL). Statistically significant predictor was not assigned. Conclusion: As the sensitivity and negative predictive value of D-dimer reached 100%, D-dimer have a role in excluding patients who might otherwise undergo diagnostic imaging for DVT in hospitalized Japanese patients with acute medical diseases/episodes.

However, in the meals of hospitals, only iron of which has been taken into account. The content of these trace elements in the enteral nutrient released after 2000 was determined by considering the content of dietary reference intakes of trace elements for Japanese and considered so not fall into deficiency. However, enteral nutrient must be used considering the content of Zn, Cu and the Zn/Cu ratio, the selenium content, and the route of administration, in order to avoid falling into deficiency.

    Disturbances in mineral and bone metabolism have a critical role in the pathogenesis of cardiovascular complications in patients with chronic kidney disease (CKD). The term 'renal osteodystrophy' has recently been replaced by 'CKD-mineral and bone disorder (CKD-MBD)', which includes abnormalities in bone and mineral metabolism and vascular calcification. The Japanese Society for Dialysis Therapy clinical practice guideline for the management of secondary hyperparathyroidism in chronic dialysis patients was originally published in Japanese in 2006, then in English in 2008. During the past 5 years, this first guideline has contributed to a considerably better understanding and control of secondary hyperparathyroidism in CKD patients by physicians, other medical professionals, and the patients themselves. However, since its publication several new therapeutic modalities have become available for Japanese dialysis patients, which added more evidence to this area. Thus, we revised the guideline to include several new policies, and the new guideline was published in Japanese in 2012. This article contains the new guideline text, and clinical significance of CKD-MBD in Japan. PMID:25019029

    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

    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 Ipragliflozin is a sodium-glucose co-transporter 2 inhibitor that can improve glycemic control and reduce body weight and blood pressure in patients with type 2 diabetes mellitus (T2DM). We evaluated the efficacy and safety of ipragliflozin in the real-world clinical setting, with a focus on the changes of body composition up to 3 months of treatment. Methods This was a prospective multicenter interventional trial. We investigated changes of the blood pressure, body composition, blood glucose, hemoglobin A1c (HbA1c), ketone bodies, lipids, and insulin after treatment with ipragliflozin (50 - 100 mg/day) for 12 weeks in Japanese patients with T2DM who showed poor glycemic control despite receiving diet and exercise therapy with or without oral antidiabetic drugs for more than 12 weeks. Results Two hundred and fifty-seven subjects were included in the efficacy analysis up to 12 weeks of treatment and 301 subjects were included in the safety analysis. From baseline to 12 weeks, HbA1c showed a change of -0.68% (95% confidence interval (CI): -0.83, -0.53) and fasting blood glucose showed a change of -23.9 mg/dL (95% CI: -30.5, -17.2), with both parameters displaying a significant reduction (P < 0.001). The difference of body weight from baseline was -1.82 kg (95% CI: -2.14, -1.50), and it also showed significant reduction (P < 0.001). Analysis of body composition revealed that body fat changed by -1.46 kg (95% CI: -1.79, -1.14, P < 0.001) and body water changed by -0.37 kg (95% CI: -0.60, -0.14, P < 0.01). Laboratory tests demonstrated improvement of liver function and the lipid profile. Adverse events (AEs) occurred in 22.6% of the subjects, with frequent events being vulvovaginal candidiasis in 2.7% and cystitis in 2.0%. Serious AEs occurred in three subjects. Conclusions In patients with T2DM, ipragliflozin improved glycemic control after 1 month of treatment and caused weight loss by reducing body fat more than body water. PMID:26767080

    Previous projects (Combell I & II) to assess clinical skills were conducted in medical schools in Catalonia, in order to introduce a model of such an assessment using standardized patients (SP). The aim of this study (Combell III) was to measure selected characteristics of our model. Seventy-three medical students in the final year at the Bellvitge teaching unit of the University of Barcelona participated in a clinical skills assessment (CSA) project that used 10 SP cases. The mean group scores for the four components of clinical skills for each day of testing were studied, and ratings for each student in the 10 sequential encounters were checked. The study also compared the clinical skills scores with their academic grades. The total case mean score (mean score of history-taking, physical examination and patient notes scores) was 51.9%, and the mean score for communication skills was 63.6%. The clinical skills scores over the 8 testing days showed no day-to-day differences. The study did not find differences among the sequential encounters for each student (training effect). There was a lack of correlation between clinical skills scores and academic grades. The project demonstrated the feasibility of the method for assessing clinical skills, confirmed its reliability, and showed that there is no correlation between scores with this method and academic examinations that mainly reflect knowledge.

    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

    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.

    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

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

    In the present retrospective single-center study, we examined the efficacy and safety of eltrombopag, a thrombopoietin (TPO) -receptor agonist (TPO-RA), and found clinical factors associated with its efficacy in Japanese patients with chronic immune thrombocytopenia (ITP). According to the definition of a response, which is to attain a platelet count of more than 50,000/μL at least once during eltrombopag treatment, 42 enrolled patients were divided into two groups: responders (29 patients, 69%) and non-responders (13 patients, 31%). In analyses of the clinical and laboratory data of these two groups, we extracted two factors that are significantly associated with a better response to eltrombopag, which have not been recognized previously, namely, (1) an older age of patients at eltrombopag initiation (≥ 70 years old) and (2) normal or decreased cellularity of iliac bone marrow (BM) biopsy at diagnosis. The significance of patient age contradicts previous findings from studies in which the Caucasian population was the major focus. However, factors such as changes of pharmacokinetics might modulate the effects of eltrombopag in older patients in Japan because East Asians show higher bioavailability of eltrombopag by as-yet-unknown mechanisms. BM cellularity in ITP may represent an impairment and/or lower responsiveness of pluripotent hematopoietic stem cells, not limited to the megakaryocyte (MgK) -platelet axis, to endogenous TPO, because recent evidence shows that TPO-RA can successfully restore hematopoiesis in aplastic anemia. These results should be useful for the therapeutic use of TPO-RA for ITP and also related thrombocytopenia in Japan.

    Pneumatosis cystoides intestinalis (PCI) is a rare gastrointestinal complication of systemic sclerosis (SSc) characterized by intramural accumulation of gas within thin-walled cysts. We report the case of an 82-year-old female patient with pneumoperitoneum due to PCI associated with SSc and review the features of the 39 Japanese cases. The median patient age was 57 years (range 24–83 years) and the male/female ratio was 1 : 12. In the recent decade, 14 out of 15 cases (93.3%) evaluated with CT scans were diagnosed with PCI. The results suggest that CT scan may be a useful diagnostic tool for detecting PCI. PCI in patients with SSc is usually benign and requires only conservative therapy. However, two patients (5.1%) with signs of peritoneal irritation required surgery. When peritoneal irritation secondary to additional pathology is observed, surgical treatment may be warranted; a precise diagnosis for this condition is therefore essential.

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

    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.

    Isolated hypoaldosteronism is a rare and occasionally life-threatening cause of salt wasting in infancy. A 2-month-old Japanese boy of unrelated parents was examined for failure to thrive and poor weight gain. Laboratory findings were hyponatremia, hyperkalemia, high plasma renin and low aldosterone levels. Spot urine analysis by gas chromatography-mass spectrometry (GC-MS) showed that urinary excretion of corticosterone metabolites was elevated. Whereas excretion of 18-hydroxycortricosterone metabolites was within the normal range, excretion of aldosterone metabolites was undetectable. The patient was therefore suspected to have aldosterone synthase deficiency type 1. Sequence analysis of CYP11B2, the gene encoding aldosterone synthase (CYP11B2), showed that the patient was a compound heterozygote for c.168G>A, p.W56X in exon 1 and c.1149C>T, p.R384X in exon 7. p.W56X was inherited from his mother and p.R384X was from his father. Since both alleles contain nonsense mutations, a lack of CYP11B2 activity was speculated to cause his condition. To our knowledge, this is the first Japanese patient in which the molecular basis of aldosterone synthase deficiency type 1 has been clarified. This case also indicates that spot urinary steroid analysis is useful for diagnosis.

    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.

    Secukinumab, a fully human anti-IL-17A monoclonal antibody, neutralizes IL-17A, a key cytokine in the pathogenesis of psoriasis. Efficacy and safety of secukinumab was evaluated in Japanese patients with moderate-to-severe plaque psoriasis as part of a large Phase 3 global study (ERASURE). In this 52-week, double-blind study (ClinicalTrials.gov Identifier: NCT01365455, JapicCTI-111529), 87 patients from Japan (11.8% of 738 patients randomized in the overall study population) were equally randomized to receive secukinumab 300 mg or 150 mg, or placebo once weekly at baseline and at Weeks 1, 2, 3 and 4, then every 4 weeks. Co-primary endpoints (Week 12) were ≥75% improvement in psoriasis area-and-severity index (PASI 75) from baseline and a score of 0 (clear) or 1 (almost clear) on a 5-point Investigator's Global Assessment scale (IGA mod 2011 0/1) versus placebo. PASI 75 and IGA mod 2011 0/1 responses at Week 12 were superior with secukinumab 300 mg (82.8% and 55.2%, respectively) or 150 mg (86.2% and 55.2%, respectively) versus placebo (6.9% and 3.4%, respectively; P < 0.0001 for all). Greater than 90% improvement in PASI (PASI 90) was also superior with secukinumab 300 mg (62.1%) or 150 mg (55.2%) versus placebo (0.0%) at Week 12 (P < 0.0001 for both). Clinical responses were sustained up to Week 52 in the majority of patients. During a 12-week induction period, adverse event incidences were 48.3% with secukinumab 300 mg, 55.2% with 150 mg, and 41.4% with placebo. Secukinumab showed robust and sustainable efficacy in symptom reduction for moderate-to-severe plaque psoriasis in the Japanese patients.

    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

    The hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome (MIM 238970) is an autosomal recessive metabolic disorder caused by a deficiency of the mitochondrial ornithine transporter, one of the urea cycle components. Mutations in the SLC25A15 gene have been coupled to the HHH syndrome. We describe a Japanese female patient with the HHH syndrome due to a novel homozygous R275X SLC25A15 mutation and male sibling who presumably carried the same mutation. He exhibited slowly progressive deterioration with seizures, a gait disturbance due to polyneuropathy, episodic confusion, and died of acute encephalopathy at 34 years of age while the proband exhibited moderate mental retardation, seizures, mild spastic paraplegia, and deafness without neurological deterioration for more than 20 years. The clinical features of previously documented patients with the homozygous SLC25A15 mutation demonstrated that genotype did not simply correlate with clinical severity. The phenotypic variability might depend on other factors, such as dietary and other genetic ones. PMID:16376511

    Diamond-Blackfan anemia (DBA) is an inherited bone marrow disease. The condition is characterized by anemia that usually presents during infancy or early childhood and congenital malformation. Several reports show that DBA is associated with mutations in the ribosomal protein (RP) genes, RPS19, RPS24, RPS17, RPL35A, RPL5, RPL11, and RPS7. Recently, 5 and 12 patients with mutations in RPS10 and RPS26, respectively, were identified in a cohort of 117 DBA probands. Therefore, we screened the DBA patients who were negative for mutations in these DBA genes for mutations in RPS10 and RPS26. The present case report describes the identification of the first Japanese DBA patient with a novel mutation in RPS10.

    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.

    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

    A review of 106 patients with multiple endocrine neoplasia (MEN) type 1 reported between 1966-1989 in Japan was conducted in order to clarify the natural history of this disease. Sporadic MEN 1 was found in 61 patients, and familial MEN 1 was found in 45 patients from 15 families. The mean ages at diagnosis of the two groups were 46.2 and 41.3 years, respectively, and the male to female ratio was 3:4. With regards to the involvement of the pituitary, parathyroid and endocrine pancreas, the combination of three endocrine glands was 31%, and that of two was 48%, in which the pituitary, parathyroid and endocrine pancreas had tumorous lesions in 60%, 88% and 63%, respectively. The first clinical manifestations of MEN 1 were the symptoms of hyperparathyroidism (32%), pituitary tumors (26%), peptic ulcer (28%) and hypoglycemia (13%). These symptoms appeared between 6 and 57 years of age (mean 34 years). The main clinical symptoms of the pituitary tumors were acromegaly and gigantism (37%), galactorrhea-amenorrhea syndrome (20%), Cushing's disease (10%) and visual disturbance due to compression of the tumor (20%). The clinical manifestations of hyperparathyroidism were mainly asymptomatic hypercalcemia (41%), nephrolithiasis (42%) and osteitis fibrosa (5%). In the patients with pancreatic tumor, Zollinger-Ellison syndrome (52%) and hypoglycemic symptoms (42%) were found. Tumors in the adrenal cortex, thyroid, carcinoid and lipoma were detected in association with MEN 1 in the frequencies of 28%, 21%, 9% and 5%, respectively. Death was reported in 37 patients between 9 and 86 years of age (mean 50.0 years). The cause of death was gastrointestinal bleeding and perforation (45%), surgery (24%) and disseminated carcinomatosis (18%). Recently, the gene predisposing to this syndrome has been assigned to chromosome 11 (11q13) in non-Japanese cases but not yet in Japanese MEN 1 patients. PMID:1679721

    Chromobacterium violaceum is sensitive to temperature and the infection is usually confined to tropical or subtropical regions. Since Japan has a warm climate, C. violaceum has been scarcely isolated from clinical specimens. With global warming, however, the geographical distribution of C. violaceum infection is likely to change. We report two cases of C. violaceum nosocomial pneumonia that occurred at an intensive care center in Japan. C. violaceum was first detected from a patient in the same center as a pathogenic organism of pneumonia. Later, the organism was isolated from sputum and a ventilator circuit tube of another patient in the center. The two patients were admitted to the center in nearby beds for several days. All of the pathogens were confirmed to be C. violaceum by the nucleic acid sequence of the 16S rRNA gene and were proven to be genetically identical organisms by pulsed field gel electrophoresis. Both patients were managed with well-humidified and heated oxygen using a venturi mask and ventilator to promote excretion of sputum. It was thought that the medical respiratory care devices that provide a humid and warm environment, an optimal condition for proliferation of C. violaceum, can contribute to C. violaceum infection in a hospital environment.

    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

    We described a 5-year-old Japanese girl with epidermolytic palmoplantar keratoderma and examined her for a keratin 9 gene mutation. Physical examination disclosed diffuse yellowish hyperkeratosis with an erythematous border limited strictly to the palms and soles. Histological examination revealed hyperkeratosis with vacuolar degeneration in the spinous and granular layers of the epidermis. Sequence analysis demonstrated an A to G transition at the middle position of codon 160 in the 1A domain of the keratin 9 gene. The amino acid at codon 160 was deduced to have changed from asparagine (Asn) to serine (Ser). This is the first case with an Asn160Ser mutation in a Japanese. The substitution of Ser for Asn at codon 160 of the keratin 9 gene is assumed to be fatal for keratin filament assembly regardless of race or ethnicity.

    This pilot study had two purposes: (1) to review recent Japanese nursing literature nursing advocacy; and (2) to obtain data from nurses on advocacy. For the second purpose, 24 nurses at a nursing college in Japan responded to a questionnaire. The concept of advocacy, taken from the West, has become an ethical ideal for Japanese nurses but one that they do not always understand, or, if they do, they find it difficult to fulfil. They cite nursing leadership support as necessary to enacting this role. Discussion on meaning of and the rationale for advocacy in a society where goodness or badness is relative to social situations and its impact may reveal two parallel but overlapping views of morality. Such a situation would not only influence notions of advocacy but also possibly render them more complex.

    Although a myopia susceptibility gene has not yet been elucidated, ten candidate regions (MYP1–MYP10) have been associated with myopia by linkage analysis employing large pedigrees. We report herein on the results of our analysis pertaining to polymorphisms of LAMA1 (alpha subunit of laminin), a promising candidate gene for high myopia present in the MYP2 region of Japanese subjects with high myopia. Three hundred and thirty Japanese subjects with high myopia at a level of greater than −9.25 D and ethnically and sex matched 330 normal controls without high myopia was enrolled in this study. The thirteen SNPs located on the LAMA1 gene were analyzed using PCR and SNP-specific fluorogenic probes. Two of the SNPs were monomorphic and none of the 11 SNPs showed statistically significant association with high myopia in the Japanese population. There is no convincing evidence to prove a connection between nucleotide sequence variations in LAMA1 and high myopia. The pairwise linkage disequilibrium (LD) mapping disclosed a strong value (D' > 0.8) and narrow ranged block within these SNPs. PMID:19668483

    Purpose Using sputum neutrophils as the primary measure, and other inflammation biomarkers, this study evaluated the anti-inflammatory effects of the combination salmeterol 50 mcg and fluticasone propionate 250 mcg (SFC 250) in Japanese patients with chronic obstructive pulmonary disease (COPD). Patients and methods Patients were treated in a randomized, double-blind, parallel group, placebo-controlled trial with SFC 250 twice daily (n=26) or placebo (n=26) for 12 weeks. At the start and end of treatment, inflammation biomarkers (sputum and serum), lung function, and health status (COPD Assessment Test [CAT] questionnaire) were measured. Results Although a numerical decrease in differential neutrophil count was observed from baseline, SFC 250 did not significantly reduce sputum neutrophils compared with placebo, nor were there significant changes from baseline in the other biomarkers (sputum or serum), lung function, or CAT, versus placebo. Squamous epithelial cell contamination in some sputum samples rendered them unacceptable for analysis, which reduced the sample size to n=19 (SFC 250) and n=10 (placebo). However, inclusion of contaminated samples did not affect the overall trend of the outcome. Ad hoc bootstrap statistical analysis showed a 27.9% (SFC 250) and 1.3% (placebo) decrease in sputum neutrophils. Sputum IL-8 decreased by 43.2% after SFC 250 but increased by 48.3% with placebo. Responder analyses showed 42% of patients had ≥20% decrease in neutrophils from baseline; and 47% of patients had a ≥200 pg/mL change in sputum IL-8 following SFC 250 versus 20% after placebo; both changes are considered clinically relevant. Conclusion This study provides additional information about inflammation in Japanese COPD patients and is the first to study the anti-inflammatory effects of SFC 250 in this context and population. In the primary analysis, SFC 250 did not produce significant changes from baseline in sputum neutrophil levels or other sputum or serum

    Background COPD-related deaths are increasing in Japan, with ~5.3 million people at risk. Methods The SHINE was a 26-week, multicenter, randomized, double-blind, parallel-group study that evaluated safety and efficacy of indacaterol (IND)/glycopyrronium (GLY) 110/50 μg once daily (od) compared with GLY 50 μg od, IND 150 μg od, open-label tiotropium (TIO) 18 μg od, and placebo. The primary end point was trough forced expiratory volume in 1 second (FEV1) at Week 26. Other key end points included peak FEV1, area under the curve for FEV1 from 5 minutes to 4 hours (FEV1 AUC5 min–4 h), Transition Dyspnea Index focal score, St George’s Respiratory Questionnaire total score, and safety. Here, we present efficacy and safety of IND/GLY in the Japanese subgroup. Results Of 2,144 patients from the SHINE study, 182 (8.5%) were Japanese and randomized to IND/GLY (n=42), IND (n=41), GLY (n=40), TIO (n=40), or placebo (n=19). Improvement in trough FEV1 from baseline was 190 mL with IND/GLY and treatment differences versus IND (90 mL), GLY (100 mL), TIO (90 mL), and placebo (280 mL) along with a rapid onset of action at Week 26. IND/GLY showed an improvement in FEV1 AUC5 min–4 h versus all comparators (all P<0.05). All the treatments were well tolerated and showed comparable effect on Transition Dyspnea Index focal score and St George’s Respiratory Questionnaire total score. The effect of IND/GLY in the Japanese subgroup was consistent to overall SHINE study population. Conclusion IND/GLY demonstrated superior efficacy and comparable safety compared with its monocomponents, open-label TIO, and placebo and may be used as a treatment option for the management of moderate-to-severe COPD in Japanese patients.

    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

    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.

    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.

    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

    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

    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.

    Abstract Background The antiproteinuric effect of the angiotensin II receptor-antagonist losartan has been observed in patients with type 2 diabetes mellitus (T2DM). Proteinuria is considered to be a predictor of the progression of kidney disease. Objective The aims of the present study were to compare and examine the ability of losartan and amlodipine to ameliorate albuminuria in hypertensive Japanese patients (systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg) with T2DM and whether the change in albuminuria was associated with a change in glomerular filtration rate (GFR). Methods This prospective, open-label, randomized, comparative study was conducted over 3 months at the Kinki University School of Medicine, Osaka-Sayama, Japan. Hypertensive patients with T2DM were enrolled and randomly assigned to 1 of 2 study groups receiving either losartan (25–100 mg/d) or the calcium channel-blocker amlodipine (2.5–5 mg/d). Urinary albumin excretion (UAE), creatinine clearance, and GFR were recorded at study initiation (baseline) and study end (month 3). The GFR was measured from the fractional renal accumulation of 99mTc-diethylenetriaminepentaacetic acid. Adverse events (AEs) were monitored by a clinical research nurse during the examination. Results Fifty patients were asked to enroll and 38 returned the informed written consent. Thirty-five Japanese patients were included in the final study analysis. Seventeen patients were assigned to the losartan group (male sex, 10 [58.8%]; mean [SD] age, 58.1 [8.2] years) and 18 were assigned to the amlodipine group (male sex, 10 [55.6%]; mean [SD] age, 57.4 [8.9] years); no significant between-group difference in demographics was observed. A significant decrease from baseline to month 3 of mean (SD) UAE was observed in the losartan group (352.5 [556.6] mg/d vs 275.7 [466.1] mg/d; P = 0.048). No significant difference in mean (SD) UAE was observed in the amlodipine group for the same time period (298

    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.

    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

    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

    Immunoglobulin M (IgM) antibody titers in paired sera from 19 encephalitis and 44 dengue hemorrhagic fever (DHF) patients in Thailand and 42 Japanese encephalitis (JE) patients in Japan were measured by the antibody capture ELISA and applied to distinguish JE virus infection from dengue virus infection. Titer distribution and the ratio of the titers against JE and dengue antigens led to the following diagnostic criteria. The specimens can be considered as positive with JE when IgM-ELISA titer showed over 200 against JE and 4-fold or more higher than titers against any types of dengue antigens. The specimens can be considered as positive with dengue infection when IgM ELISA titer showed over 200 against one of the 4 types of dengue antigens and 4-fold or more higher than against JE antigen. Based on these criteria, 41 of 42 patients in Japan and 11 of 19 encephalitis patients in Thailand could be diagnosed as having JE virus infection while 2 of 19 encephalitis patients in Thailand and 26 of 44 DHF patients in Thailand could be diagnosed as having dengue virus infections.

    The criteria that "illness is biographical crisis od the individual" and that the only medicine is "personal medicine" is stressed. Clinical medicine, which covers medicine in its entirety, demands conceptual and doctrinal reaffirmations so that gradually the patient can come to be dealt with as a human being fron a holistic point of view, which commences with his complaint and consultation, continues with the interview and semiology, to finish with the diagnosis and therapy which, although in some cases it may be surgical, is still medical and integral. All the steps mentioned are bio-socio-cultural thus, whether in the practice of general clinical medicine or in the most specialized and technologically sophisticated clinical medicine, the animist component is not lacking and demands a minimum degree of "psychosomatic" Knowledge. The use of a psychotherapeutic technique is proposed which, while based on the psychoanalysis theory, is distanced technically from it as a "psychotherapy on limited time and goals", which abbreviates the disease, and is projected not as the "focus" of therapeutic work, but as a re-evaluation of the "life style" of each individual, and tends to help to develop a "project for life" suited to the possible personal, familiar and social well-being of the "patient". Technically speaking, this modality of brief psychotherapy is based on the nonuse of transferential interpretations, on impeding the regression od the patient, on facilitating a cognitice-affective development of his conflicts and thus obtain an internal object mutation which allows the transformation of the "past" into true history, and the "present" into vital perspectives. This technique is within reach of every health professional.

    Rheumatoid arthritis (RA) is a chronic systemic inflammatory disease. Certain HLA-DRB1 “shared-epitope” alleles are reported to be positively associated with increased RA susceptibility, whereas some of the other alleles may be negatively associated. However, studies on the latter are rare. Here, we focus on the protective effects of DRB1 alleles in Japanese RA patients in an association study. Relative predispositional effects (RPE) were analyzed by sequential elimination of carriers of each allele with the strongest association. The protective effects of DRB1 alleles were investigated in patients stratified according to whether they possessed anti-citrullinated peptide antibodies (ACPA). The DRB1*13:02 allele was found to be negatively associated with RA (P = 4.59×10−10, corrected P (Pc) = 1.42×10−8, odds ratio [OR] 0.42, 95% CI 0.32–0.55, P [RPE] = 1.27×10−6); the genotypes DRB1*04:05/*13:02 and *09:01/*13:02 were also negatively associated with RA. The protective effect of *13:02 was also present in ACPA-positive patients (P = 3.95×10−8, Pc = 1.22×10−6, OR 0.42, 95%CI 0.31–0.58) whereas *15:02 was negatively associated only with ACPA-negative RA (P = 8.87×10−5, Pc = 0.0026, OR 0.26, 95%CI 0.12–0.56). Thus, this study identified a negative association of DRB1*13:02 with Japanese RA; our findings support the protective role of DRB1*13:02 in the pathogenesis of ACPA-positive RA. PMID:24911054

    Aims We examined the efficacy, safety and tolerability of canagliflozin, a sodium glucose co-transporter 2 inhibitor, in Japanese patients with type 2 diabetes (T2DM) undergoing diet and exercise therapy. Methods Patients aged 20–80 years with T2DM diagnosed ≥3 months previously, and HbA1c of 6.9–9.9% were randomized to 50, 100, 200 or 300 mg canagliflozin or placebo once daily for 12 weeks. The primary and secondary endpoints were changes in HbA1c, fasting plasma glucose (FPG), urinary glucose/creatinine and postprandial glycaemic parameters following a meal test. The safety assessments included adverse events (AEs) and clinical laboratory tests. Results Overall, 383 patients were randomized to receive either placebo (n = 75), or 50 mg (n = 82), 100 mg (n = 74), 200 mg (n = 77) or 300 mg canagliflozin (n = 75). At week 12, significant reductions in HbA1c were observed in all canagliflozin groups relative to placebo (−0.61, –0.80, –0.79 and −0.88% for 50, 100, 200 and 300 mg, respectively, versus +0.11% for placebo; all, p < 0.01). FPG and postprandial glycaemic parameters improved significantly in the canagliflozin groups. Body weight was significantly decreased by canagliflozin. No deaths or drug-related serious AEs were reported. There was no dose-dependent increase in the incidence of AEs in the canagliflozin groups. The incidence of hypoglycaemia was low; episodes were not severe or dose dependent. Canagliflozin did not affect serum creatinine levels or the urinary albumin/creatinine ratio. Conclusions Treatment with canagliflozin for 12 weeks significantly improved glycaemic control and reduced body weight in Japanese patients with T2DM. Canagliflozin was well tolerated. PMID:23782594

    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

    Objective Dysregulation of c-MET signaling pathway results from various molecular mechanisms including mutations, amplification, and overexpression. Overexpression and amplification of c-MET have been correlated with poor clinical outcome in gastric cancer, whereas the associations between c-MET polymorphisms and prognosis have not been well defined. We examined the prognostic impact of functional polymorphisms of MET gene on clinical outcome in gastric cancer. Methods Candidate polymorphisms of MET gene were analyzed by PCR-based direct sequencing for the associations with clinical outcome across three independent cohorts, including 161 Japanese, 101 U.S. and 63 Austrian patients, with loco-regional gastric cancer treated with surgery. Results The univariable analysis showed patients with any G (A/G or G/G genotype) allele of MET rs40239 had significantly longer disease-free survival and overall survival compared to those with the AA genotype in the Japanese cohort (HR: 0.43; P=0.001, HR: 0.47; P=0.006, respectively); this remained significant upon multivariable analysis adjusted for age, sex, stage, and type of adjuvant therapy (HR: 0.48; P=0.009, HR: 0.50; P=0.017, respectively). However, there was no significant association of the polymorphism with clinical outcome in the U.S. and Austrian cohort. When stratified by gender in the Japanese cohort, males, but not females, with the G allele maintained a clinical outcome benefit in both univariable and multivariable analysis. Conclusions The MET rs40239 may serve as a prognostic biomarker in loco-regional gastric cancer. These data also suggest that genetic variants of the c-MET may have a gender-related difference in the impact on clinical outcome. PMID:25203738

    Study Design Retrospective study. Purpose To determine the presence and frequency of factors for degenerative spondylolisthesis (DS) in patients with hip osteoarthritis (OA). Overview of Literature OA of the hip joint (hip OA) in Japanese patients is associated with a high incidence of degenerative lumbar spondylolisthesis (DS). However the associated factors for DS in patients with hip OA are unclear. Methods The study included 518 patients (59 men and 459 women) with a mean age of 63.8 years who underwent total hip arthroplasty for hip OA at our hospital between January 2004 and May 2014. The presence of DS was assessed using preoperative standing lateral radiographs of the hip joint including the lower lumbar spine. To identify the associated factors for DS in patients with hip OA, multiple logistic regression analysis was conducted in which the presence or absence of DS was used as a dependent variable, and age, female sex, body mass index (BMI), sacral slope (SS), Crowe classification, and primary OA (P-OA) not associated with acetabular dysplasia were independent variables. Results Patients with DS accounted for 114 (22.0%) of 518 cases. In multiple logistic regression analysis to identify associated factors for DS in patients with hip OA, the odds ratio for age was 1.05 (95% confidence interval [CI], 1.02–1.08), female sex was 2.48 (95% CI, 1.11–5.54), BMI was 1.08 (95% CI, 1.02–1.14), SS was 1.07 (95% CI, 1.04–1.09), Crowe classification was 0.60 (95% CI, 0.40–0.91), and P-OA was 1.90 (95% CI, 1.20–3.75). Conclusions Age, female sex, BMI, SS, low Crowe classification, and P-OA are independently associated factors for DS in patients with hip OA. PMID:27790324

    Background Nuclear factor-kappaB (NF-κB) and CCL2/CCR2 chemokine axis play a central role in tumor progression such as stimulation of angiogenesis, acceleration of tumor invasion and migration, and suppression of innate immunosurveillance in the macrophage-related functions. There have been few reports regarding association of the macrophage function-related genes with the clinical outcome in gastric cancer. We hypothesized that variants in genes encoding for NF-κB and CCL2/CCR2 axis may predict prognosis in gastric cancer and tested whether the functional single-nucleotide polymorphisms (SNPs) will be associated with clinical outcome in patients with gastric cancer across two independent groups. Patients and methods This study enrolled two cohorts which consisted of 160 Japanese patients and 104 US patients with locoregional gastric cancer. Genomic DNA was analyzed for association of 11 SNPs in NFKB1, RELA, CCL2, and CCR2 with clinical outcome using PCR-based direct DNA sequencing. Results The univariable analysis showed four SNPs had significant association with clinical outcome in the Japanese cohort, NFKB1 rs230510 remained significant upon multivariable analysis. The patients with the A allele of the NFKB1 rs230510 had significantly longer overall survival (OS) compared with those with the T/T genotype in both the Japanese and US cohort in the univariable analysis. In contrast, genotypes with the T allele of CCL2 rs4586 were significantly associated with shorter OS compared with the C/C genotype in the US cohort [hazard ratio (HR) 2.43; P = 0.015] but longer OS in the Japanese cohort (HR 0.58; P = 0.021), resulting in the statistically significant opposite impact on OS (P = 0.001). Conclusions Our study provides the first evidence that the NFKB1 rs230510 and CCL2 rs4586 are significantly associated with the clinical outcome in patients with locoregional gastric cancer. These results also suggest that the genetic predisposition of the host may dictate the

    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.

    Objectives To conduct Japanese subgroup analyses of a randomized, global Phase II study of axitinib with and without dose titration in first-line metastatic renal cell carcinoma and to explore predictive factors for axitinib efficacy in first-line metastatic renal cell carcinoma. Methods The data included 44 Japanese and 169 non-Japanese treatment-naïve patients with metastatic renal cell carcinoma. Patients received twice-daily axitinib 5 mg during a 4-week lead-in period. Patients who met the pre-defined randomization criteria were stratified by Eastern Cooperative Oncology Group performance status and randomly assigned (1:1) to axitinib or placebo titration. The primary endpoint was objective response rate; secondary endpoints included progression-free survival and safety. Predictive factors were analyzed using data from all patients. Results The objective response rate (95% confidence interval) was 66% (50–80%) vs. 44% (36–52%) in Japanese and non-Japanese patients, respectively. At the primary analysis, median progression-free survival could not be estimated for Japanese patients, and was 27.6 months (95% confidence interval: 16.6–33.2) in an updated analysis. Hypertension, diarrhea, hand–foot syndrome, dysphonia, hypothyroidism and proteinuria were common adverse events in Japanese patients. Due to a small number of randomized patients, effects of axitinib dose titration could not sufficiently be confirmed among Japanese patients. The multivariate analysis identified time from histopathological diagnosis to treatment and sum of the longest diameter for target lesion at baseline as independent predictive factors for progression-free survival. Conclusions Axitinib is effective and well tolerated as first-line metastatic renal cell carcinoma therapy in Japanese patients. Predictive factors for axitinib efficacy endpoints identified in this setting warrant further investigation. PMID:27572087

    The present study examined long-term efficacy outcomes in a subgroup of postmenopausal, estrogen receptor-positive Japanese breast cancer patients from the Pre-Operative "Arimidex" Compared with Tamoxifen trial, following pre-operative (3 months) and post-operative (5 years) adjuvant treatment with either anastrozole or tamoxifen. Patients with large, potentially operable, locally-advanced breast cancer were randomized to receive anastrozole (1 mg/day) plus tamoxifen placebo or tamoxifen (20 mg/day) plus anastrozole placebo pre-operatively. After surgery at 3 months, patients continued on the same study medication as adjuvant therapy for up to 5 years or until recurrence, intolerable toxicity or withdrawal of patient consent. Recurrence-free survival and overall survival were measured from the date of randomization to the date of recurrence or death, whichever occurred first. Patients were monitored for adverse events throughout the study period and up to 30 days following administration of the last study medication. During post-operative adjuvant therapy, 4/48 (8%) anastrozole and 25/49 (51%) tamoxifen patients experienced recurrence. There was a significant difference in recurrence-free survival between the two groups (hazard ratio 0.14; 95% confidence interval 0.05-0.41; P = 0.0003). There was a significant increase in overall survival with anastrozole (0.21; 0.05-0.96; P = 0.0436) and there were 2/48 (4%) and 10/49 (20%) deaths with anastrozole and tamoxifen, respectively. Most patients responding to pre-operative therapy remained recurrence-free. Sequential pre-operative/post-operative treatment with anastrozole resulted in lower recurrence and death rates, compared with tamoxifen.

    PubMed Central

    2010-01-01

    T cell disorders have been poorly understood until recently. Lack of knowledge of underlying molecular mechanisms together with incomplete data on long term outcome have made it difficult to assess prognosis and give the most effective treatment. Rapid progress in defining molecular defects, improved supportive care and much improved results from hematopoietic stem cell transplantation (HSCT) now mean that curative treatment is possible for many patients. However, this depends on prompt recognition, accurate diagnosis and careful treatment planning. This review will discuss recent progress in our clinical and molecular understanding of a variety of disorders including: severe combined immunodeficiency, specific T cell immunodeficiencies, signaling defects, DNA repair defects, immune-osseous dysplasias, thymic disorders and abnormalities of apoptosis. There is still much to discover in this area and some conditions which are as yet very poorly understood. However, with increased knowledge about how these disorders can present and the particular problems each group may face it is hoped that these patients can be recognized early and managed appropriately, so providing them with the best possible outcome.

    Introduction Two studies were carried out to investigate the efficacy and safety of luseogliflozin added to existing oral antidiabetic drugs (OADs) in Japanese type 2 diabetic patients inadequately controlled with OAD monotherapy. Materials and Methods In the trial involving add-on to sulfonylureas (study 03-1), patients were randomly assigned to receive luseogliflozin 2.5 mg or a placebo for a 24-week double-blind period, followed by a 28-week open-label period. In the open-label trial involving add-on to other OADs; that is, biguanides, dipeptidyl peptidase-4 inhibitors, thiazolidinediones, glinides and α-glucosidase inhibitors (study 03-2), patients received luseogliflozin for 52 weeks. Results In study 03-1, luseogliflozin significantly decreased glycated hemoglobin at the end of the 24-week double-blind period compared with the placebo (–0.88%, P < 0.001), and glycated hemoglobin reduction from baseline at week 52 was –0.63%. In study 03-2, luseogliflozin added to other OADs significantly decreased glycated hemoglobin from baseline at week 52 (–0.52 to –0.68%, P < 0.001 for all OADs). Bodyweight reduction was observed in all add-on therapies, even with agents associated with weight gain, such as sulfonylureas and thiazolidinediones. Most adverse events were mild in severity. When added to a sulfonylurea, incidences of hypoglycemia during the double-blind period were 8.7% and 4.2% for luseogliflozin and placebo, respectively, but no major hypoglycemic episodes occurred. The frequency and incidences of adverse events of special interest for sodium glucose cotransporter 2 inhibitors and adverse events associated with combined OADs were acceptable. Conclusions Add-on therapies of luseogliflozin to existing OADs improved glycemic control, reduced bodyweight and were well tolerated in Japanese type 2 diabetic patients. These trials were registered with the Japan Pharmaceutical Information Center (add on to sulfonylurea: JapicCTI-111507; add on to

    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.

A survey was conducted using an anonymous questionnaire for attendees of a lecture on antiviolence in health care institutions. Patient-to-staff verbal violence was associated with staff-to-staff verbal violence (odds ratio [OR] = 1.43; 95% confidence interval [CI]: 1.16-1.66). Patient-to-staff physical violence was associated with staff-to-staff physical violence (OR = 7.80; 95% CI: 1.86-13.5) and patient-to-patient verbal violence (OR = 2.69; 95% CI: 1.18-5.42). Patient-to-staff sexual harassment was associated with staff-to-staff sexual harassment (OR = 6.55; 95% CI: 3.59-8.91) and patient-to-patient verbal violence (OR = 2.96; 95% CI: 1.44-5.17). Staff who had experienced patient-to-staff violence were likely to have experienced violence by other staff and to have witnessed or reported violence among patients.

    Basal cell nevus syndrome (BCNS or Gorlin syndrome, OMIM: 109400) is a rare autosomal dominant disorder with high penetrance. It is characterized by developmental anomalies and predisposition to tumors (for example, basal cell carcinoma (BCC) and medulloblastoma). PTCH1, the human homolog of the Drosophila patched gene, was identified as a gene responsible for BCNS. The PTCH1 protein is a Hedgehog (Hh) protein receptor and is pivotal for early development, stem cell maintenance and/or differentiation. We analyzed the six Japanese families with BCNS and identified six germline mutations in the PTCH1 gene. One family had a nonsense mutation (c.1196G>A), one had a 1-bp deletion (c.2029delA), two had 2-bp deletions (c.239_240delGA and c.1670_1671delCA) and one had a 58-bp duplication (c.1138_1195dup). They caused premature termination, resulting in the truncation of the PTCH1 protein. Analysis of a high-density single nucleotide polymorphism (SNP) mapping array showed a large approximately 1.2-Mb deletion, including the PTCH1 gene in one allele, in a family in which PTCH1 mutations were not identified at the sequence level. These data indicated that all the six families who were diagnosed with BCNS had mutations in the PTCH1 gene and that a single copy of a PTCH1 mutation causes BCNS. PMID:19557015

    Endogenous Cushing’s syndrome is an endocrine disease resulting from chronic exposure to excessive glucocorticoids produced in the adrenal cortex. Although the ultimate outcome remains uncertain, functional and morphological brain changes are not uncommon in patients with this syndrome, and generally persist even after resolution of hypercortisolemia. We present an adolescent patient with Cushing’s syndrome who exhibited cognitive impairment with brain atrophy. A 19-year-old Japanese male visited a local hospital following 5 days of behavioral abnormalities, such as money wasting or nighttime wandering. He had hypertension and a 1-year history of a rounded face. Magnetic resonance imaging (MRI) revealed apparently diffuse brain atrophy. Because of high random plasma cortisol levels (28.7 μg/dL) at 10 AM, he was referred to our hospital in August 2011. Endocrinological testing showed adrenocorticotropic hormone-independent hypercortisolemia, and abdominal computed tomography demonstrated a 2.7 cm tumor in the left adrenal gland. The patient underwent left adrenalectomy in September 2011, and the diagnosis of cortisol-secreting adenoma was confirmed histologically. His hypertension and Cushingoid features regressed. Behavioral abnormalities were no longer observed, and he was classified as cured of his cognitive disturbance caused by Cushing’s syndrome in February 2012. MRI performed 8 months after surgery revealed reversal of brain atrophy, and his subsequent course has been uneventful. In summary, the young age at onset and the short duration of Cushing’s syndrome probably contributed to the rapid recovery of both cognitive dysfunction and brain atrophy in our patient. Cushing’s syndrome should be considered as a possible etiological factor in patients with cognitive impairment and brain atrophy that is atypical for their age. PMID:25246796

    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

    A 31-year-old Japanese female had stayed in Australia from January to May 2013. She presented with a sudden onset of left ankle and right knee arthralgia in March but neither fever nor rash was present. As her arthralgia persisted, she visited our hospital upon her return to Japan in May. When she came to our hospital, she complained of left ankle and right knee pain, but no arthritis findings. Laboratory findings were also within normal ranges. Ross River virus (RRV) antibody levels were examined as she was suspected of having contracted the disease in Australia. RRV IgG antibody and IgM antibody were positive, and the patient was confirmed as a case of acute RRV disease. RRV disease is endemic in Australia, but there are no prior reports of the disease in Japan. This is the first case of RRV disease confirmed in Japan. Typical symptoms of RRV disease include arthralgia, fever, and rash. Our patient had only arthralgia. With the increase in the number of travelers and length of stay in RRV endemic regions, health care providers need to consider the disease in their differential diagnosis, among returning travelers with arthralgia, fever, rash and a travel history to RRV-endemic regions.

    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

    Evidence from clinical trials should contribute to informed decision making and a learning health care system. People frequently, however, find participating in clinical trials meaningless or disempowering. Moreover, people often do not incorporate trial results directly into their decision making. The lack of patient centeredness in clinical trials may be partially addressed through trial design. For example, Bayesian adaptive trials designed to adjust in a pre-specified manner to changes in clinical practice could motivate people and their health care providers to view clinical trials as more applicable to real-world clinical decisions. The way in which clinical trials are designed can transform the evidence generation process to be more patient centered, providing people with an incentive to participate or continue participating in clinical trials. In order to achieve the transformation to patient-centeredness in clinical trial decisions, however, there is a need for transparent and reliable methods and education of trial investigators and site personnel.

    Background To assess the outcome of neoadjuvant chemohormonal therapy comprising complete androgen blockade followed by treatment with docetaxel and estramustine phosphate before radical prostatectomy in Japanese patients with a high risk of localized prostate cancer (PCa). Methods Complete androgen blockade followed by 6 cycles of docetaxel (30 mg/m2) with estramustine phosphate (560 mg) were given to 18 PCa patients before radical prostatectomy. Subsequently, the clinical and pathological outcomes were analyzed. Results No patients had severe adverse events during chemohormonal therapy, and hence they were treated with radical prostatectomy. Two patients (11.1%) achieved pathological complete response. Surgical margins were negative in all patients. At a median follow-up of 18 months, 14 patients (77.8%) were disease-free without PSA recurrence. All 4 patients with PSA recurrence had pathologic T3b or T4 disease and 3 of these 4 patients had pathologic N1 disease. Conclusion We found that neoadjuvant chemohormonal therapy with complete androgen blockade followed by treatment with docetaxel and estramustine phosphate before radical prostatectomy was safe, feasible, and associated with favorable pathological outcomes in patients with a high risk of localized PCa.

    This study aimed to measure quality of life (QOL) of the primary family caregivers for patients with Prader-Willi syndrome (PWS). Comparisons were made between caregivers' QOL in regard to their dependents' genotype and age group. The participants with PWS consisted of 22 children (aged from 6 to 12 years) and 23 adolescents (aged from 13 to 19 years), including 6 children and 7 adolescents with maternal uniparental disomy (mUPD) and 16 children and 16 adolescents with deletion (DEL). The QOL of the primary family caregiver for each patient was assessed using the Japanese version of the WHOQOL-BREF. To examine the effect that age (children vs. adolescents) and genotype (DEL vs. mUPD) have on the QOL of caregivers, a two-way ANOVA was conducted, followed by the Bonferroni procedure to test the simple main effects. The two age groups and the two genotypes of PWS were used as independent variables and the total QOL of caregivers as a dependent variable. The two-way ANOVA (F(1, 41) = 6.98, P < 0.05), followed by the Bonferroni procedure, showed the following: the total QOL of caregivers of DEL adolescents showed little difference from that with DEL children, but the QOL of caregivers for mUPD adolescents was shown to be lower than that with mUPD children along with that of caregivers with DEL adolescents. There is hence a growing tendency for the deterioration in the QOL of caregivers to manifest itself later in the patients' adolescence, found mainly with mUPD patients.

    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%).

    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.

    Background Self-rated oral health is a valid and useful summary indicator of overall oral health status and quality of life. However, few studies on perception of oral health have been conducted among Japanese young adults. This study investigated whether oral health behavior, subjective oral symptoms, or clinical oral status were associated with self-rated oral health in Japanese young adults. Methods This cross-sectional survey included 2,087 students (1,183 males, 904 females), aged 18 and 19 years, at Okayama University, Japan. A self-administered questionnaire was distributed and an oral examination was performed. Results In a structural equation modeling analysis, the score of decayed, missing and filled teeth (DMFT) significantly affected self-rated oral health (p <0.05) and the effect size was highest. Malocclusion, subjective symptoms of temporomandibular disorders (TMD) and stomatitis, and poor oral health behavior significantly induced self-rated poor oral health with small effect sizes (p <0.05). Clinical periodontal conditions and Oral Hygiene Index-simplified were not related to self-rated oral health. Conclusion Self-rated oral health was influenced by subjective symptoms of TMD and stomatitis, oral health behavior, the score of DMFT, and malocclusion. The evaluation of these parameters may be a useful approach in routine dental examination to improve self-rated oral health in university students. PMID:24195632

    In the present study, we searched for genetic alterations of the entire coding region of PTEN/MMAC1, a recently isolated candidate tumor suppressor gene, in 178 specimens from Japanese patients with various malignant tumors by the polymerase chain reaction-single strand conformation polymorphism method. The samples consisted of 11 glioblastoma multiformes (GBMs), 14 astrocytomas, 47 breast cancers, 25 non-small cell lung cancers, 9 small cell lung cancers, 8 pancreatic cancers, 24 renal cell carcinomas, 20 ovarian cancers, and 20 metastatic lung tumors from various organs. Only one somatic frameshift mutation at codon 319 was observed in one (9%) of eleven GBMs. Our results suggest that mutation of the PTEN/MMAC1 gene does not play a major role in carcinogenesis, at least in the tumor types from Japanese patients analyzed in this study.

    This study was performed to explore the possibility of an association between polymorphisms within the uridine diphosphate glucuronosyltransferase 1A1 gene (UGT1A1) and hyperbilirubinemia arising during tocilizumab therapy. We examined the distributions of 3 variant alleles, UGT1A1*6, *28, and *27, in 46 Japanese patients with rheumatoid arthritis (RA) who had received tocilizumab therapy for at least 24 weeks, grouped the patients according to their carriage status of these UGT1A1 variants, and determined the frequency of hyperbilirubinemia in each of the groups. Of the 46 patients treated with tocilizumab, 34 maintained normal bilirubin levels after 24 weeks, whereas the remaining 12 developed mild or moderate hyperbilirubinemia. Patients carrying 2 copies of UGT1A1*28 (*28/*28) were more likely to develop hyperbilirubinemia than those without UGT1A1*28. In addition, patients carrying 2 copies of variant alleles, either as homozygotes (UGT1A1*6/*6 or *28/*28) or as compound heterozygotes (UGT1A1*6/*28), were at higher risk of hyperbilirubinemia as compared with those without either UGT1A1*6 or UGT1A1*28 (odds ratio [OR] 28.33; 95% confidence interval [CI] 2.39-336.00; p = 0.005). Multivariate logistic regression analysis confirmed the strong association of tocilizumab-induced hyperbilirubinemia with the presence of 2 copies of variant alleles (OR 25.51; 95% CI 2.35-276.53; p = 0.008), yielding an area under the receiver operating characteristics curve of 0.78 (95% CI 0.60-0.95, p = 0.005). Tocilizumab can induce hyperbilirubinemia in RA patients, especially those carrying UGT1A1*6/*6, *6/*28, and *28/*28 genotypes. Considering this genetic association, it may be unnecessary to withdraw this drug from RA patients in the absence of other signs of hepatic injury. Given that tocilizumab has the potential to inhibit UGT1A1-mediated glucuronidation, however, it may inhibit not only bilirubin metabolism but also UGT1A1-dependent detoxification of drugs, thereby

    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

    A questionnaire survey was conducted in Japan to investigate the causes and prevalence of death related to Dravet syndrome. The questionnaire was delivered to 246 hospitals at which physicians were treating childhood epilepsy to gain information about the total number of patients with Dravet syndrome and the prevalence of early death due to the disorder. Responses to the survey were collected from 91 hospitals, and a total of 63 of 623 patients with Dravet syndrome had died. Data from 59 of these patients were analyzed. The age at death for these patients ranged from 13 months to 24 years and 11 months, with a median age of 6 years and 8 months. The causes of mortality included sudden death in 31 patients (53%), acute encephalopathy with status epilepticus (SE) in 21 patients (36%), drowning in 6 patients (10%), and other causes in one patient (1%). The incidence of sudden death reached a first peak at 1-3 years of age and a second peak at 18 years and older. In contrast, the incidence of acute encephalopathy with SE reached a peak at 6 years of age. Seven of the 10 patients who underwent SCN1A mutation analysis exhibited positive mutations but exhibited no consistent phenotype. The prevalence of Dravet syndrome-related mortality was 10.1%. The incidence of sudden death and acute encephalopathy with SE was higher in infancy (1-3 years) and at early school ages (with a peak at 6 years), respectively. Neither the treatment nor the number of seizures was associated with any cause of mortality. Factors leading to a fatal outcome are difficult to predict.

    We analyzed the antithrombin (AT) gene in four unrelated Japanese patients with an AT deficiency, and individually identified four distinct mutations in the heterozygous state. There were two novel mutations, 2417delT leading to a frameshift with a premature termination at amino acid -3 (FS-3Stop) and C2640T resulting in a missense mutation (Ala59Val). Previously reported mutations, T5342C (Ser116Pro) and T72C (Met-32Thr), were also found in the other two patients. To understand the molecular basis responsible for the AT deficiency in these patients, in vitro expression experiments were performed using HEK293 cells transfected with either wild type or respective mutant AT expression vector. We found that -3Stop-AT and -32Thr-AT were not secreted into the culture media, whereas 116Pro-AT and 59Val-AT were secreted normally. We further studied the heparin cofactor activity and the binding to heparin of each recombinant AT molecule. Ser116Pro mutation significantly impaired the binding affinity to heparin resulting in a reduced heparin cofactor activity. In contrast, we found that Ala59Val mutant AT unexpectedly showed a normal affinity to heparin, but severely impaired the heparin cofactor activity. Our findings suggested that FS-3Stop and Met-32Thr mutations are responsible for type I AT deficiency, whereas Ser116Pro and Ala59Val mutations contribute to type II AT deficiency, confirming that there were diverse molecular mechanisms of AT deficiency depend upon discrete AT gene abnormalities as reported previously.

    Medical nutrition therapy for the management of diabetes plays an important role in preventing diabetes complications and managing metabolic control. However, little is known about actual eating habits of individuals with type 2 diabetic mellitus (T2DM), especially in Japan. Therefore, we sought to (1) assess the dietary intake of individuals with T2DM, and (2) characterize their intake relative to national recommendations. This cross-sectional study involved 149 patients (77 males and 72 females) aged 40-79 years with T2DM recruited at a Kyoto hospital. Dietary intake was assessed using a validated self-administered diet history questionnaire. Under-consumption, adequacy, and over-consumption, of nutrients were compared to the age- and sex-based standards of the Japanese Dietary Reference Intakes. Among the results, most notable are (1) the inadequacy of diets in men with respect to intake of vitamins and minerals, likely owing to low intake of vegetables and fruits; (2) excess contributions of fat intake to total energy in both sexes; and (3) excess consumption of sweets and beverages relative to the national average. The prevalence of diabetes complications may be increasing because of a major gap between the typical dietary intake of individuals with T2DM and dietary recommendation.

    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

    Every year hundreds of patients voluntarily participate in clinical trials across Ireland. However, little research has been done as to how patients find the experience. This survey was conducted in an attempt to ascertain clinical trial participants' views on their experience of participating in a clinical trial and to see and how clinical trial participation can be improved. One hundred and sixty-six clinical trial participants who had recently completed a global phase IV cardiovascular endpoint clinical trial were sent a 3-page questionnaire. Ninety-one (91%) respondents found the experience of participating in a clinical trial a good one with 85 (84.16%) respondents saying they would recommend participating in a clinical trial to a friend or relative and eighty-five (87.63%) respondents feeling they received better healthcare because they had participated in a clinical trial.

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

    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

    Mutations in transcription factors genes, which are well regulated spatially and temporally in the pituitary gland, result in congenital hypopituitarism (CH) in humans. The prevalence of CH attributable to transcription factor mutations appears to be rare and varies among populations.This study aimed to define the prevalence of CH in terms of nine CH-associated genes among Japanese patients. We enrolled 91 Japanese CH patients for DNA sequencing of POU1F1, PROP1, HESX1, LHX3, LHX4, SOX2, SOX3, OTX2, and GLI2. Additionally, gene copy numbers for POU1F1, PROP1, HESX1, LHX3, and LHX4 were examined by multiplex ligation-dependent probe amplification. The gene regulatory properties of mutant LHX4 proteins were characterized in vitro. We identified two novel heterozygous LHX4 mutations, namely c.249-1G>A, p.V75I, and one common POU1F1 mutation, p.R271W. The patient harboring the c.249-1G>A mutation exhibited isolated growth hormone deficiency at diagnosis and a gradual loss of ACTH, whereas the patient with the p.V75I mutation exhibited multiple pituitary hormone deficiency. In vitro experiments showed that both LHX4 mutations were associated with an impairment of the transactivation capacities of POU1F1 andαGSU, without any dominant-negative effects. The total mutation prevalence in Japanese CH patients was 3.3%. This study is the first to describe, a gradual loss of ACTH in a patient carrying an LHX4 mutation. Careful monitoring of hypothalamic-pituitary -adrenal function is recommended for CH patients with LHX4 mutations.

    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

    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.

    Background and objectives Renal histological injury patterns in type 2 diabetes are heterogeneous. We compared renal histological injury patterns using renal biopsy findings with renal function and followed up renal functional changes in normoalbuminuric and microalbuminuric patients with type 2 diabetes to determine whether renal function progresses according to injury patterns. Design, setting, participants, and measurements We examined 111 patients with type 2 diabetes with percutaneous renal biopsy (78 men, 52±11 years old, 59 normoalbuminuria, 52 microalbuminuria) and followed up 37 cases for 11 years. Light microscopy of tissues revealed renal injury patterns as: category I (CI), normal or near-normal structure; category II (CII), typical diabetic glomerulopathy; category III (CIII), atypical (disproportionately severe tubulointerstitial/vascular damage with no/mild glomerulopathy). Results There were 29 CI, 62 CII, and 20 CIII patients. CII patients had a higher frequency of chronic kidney disease (CKD) G3-4, while the injury pattern distribution was not different among the albuminuria stages. The mean glomerular volume and volume fraction of cortical interstitium were larger than those of controls. The arteriolar hyalinosis index was larger in CII and CIII, while the percent global glomerular sclerosis was larger in CKD G3-4 compared with CKD G1-2. Renal function at follow-up was decreased in CII and CIII compared with the baseline estimated glomerular filtration rate (eGFR), while the GFR decline rate was faster in CII. Conclusions In normoalbuminuric and microalbuminuric patients with type 2 diabetes, loss of GFR could indicate typical diabetic glomerulosclerosis and a high frequency of global glomerular sclerosis. Urinary biomarkers identifying histological patterns of renal injury are necessary because GFR decline rates differed according to histological injury patterns. PMID:25452869

    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.

    Although exercise oscillatory ventilation has emerged as a potent independent risk factor for adverse prognosis in heart failure, it is not well known whether cardiac rehabilitation can improve oscillatory ventilation. In this study, we investigated the magnitude of oscillations in ventilation before and after cardiac rehabilitation in chronic heart failure patients with exercise oscillatory ventilation. Cardiac rehabilitation (5-month program) was performed in 26 patients with chronic heart failure who showed an oscillatory ventilation pattern during cardiopulmonary exercise testing (CPX). After the 5-month rehabilitation program was completed, the patients again underwent CPX. To determine the magnitude of oscillations in ventilation, the amplitude and cycle length of the oscillations were calculated and compared with several other parameters, including biomarkers that have established prognostic value in heart failure. At baseline before cardiac rehabilitation, both oscillation amplitude (R = 0.625, P < 0.01) and cycle length (R = 0.469, P < 0.05) were positively correlated with the slope of minute ventilation vs. carbon dioxide production. Plasma BNP levels were positively correlated with amplitude (R = 0.615, P < 0.01) but not cycle length (R = 0.371). Cardiac rehabilitation decreased oscillation amplitude (P < 0.01) but failed to change cycle length. The change in amplitude was positively correlated with the change in BNP levels (R = 0.760, P < 0.01). Multiple regression analysis showed that only the change in amplitude was an independent predictor of the change in BNP levels (R = 0.717, P < 0.01). A 5-month cardiac rehabilitation program improves exercise oscillatory ventilation in chronic heart failure patients by reducing the oscillation amplitude. This effect is associated with a reduction of plasma BNP levels, potentially contributing to an improvement of heart failure.

    The objective of this study was to investigate physicians' awareness and use of the Japanese Society of Hypertension (JSH) Guidelines for the Management of Hypertension (JSH2004 and JSH2009), and determine what changes need to be implemented in the future. A questionnaire was used to survey physicians' awareness and their use of JSH2004 and JSH2009. Physicians attending educational seminars on hypertension that were held during the months after the publication of JSH2009 (January-April 2009) were asked to participate in the survey. Of the 5795 respondents, 88% were aware of the JSH2009 publication. Furthermore, physicians were also aware of JSH2004, with about 90% using JSH2004 in their practice. A hypertension blood pressure (BP) reference value of 140/90 mm Hg was used by 55% in office BP, whereas 31% used 135/85 mm Hg for home BP. Target BP levels used by physicians were 130/80 mm Hg for patients with diabetes or kidney disease (52%) and for elderly patients with diabetes or kidney disease (45%), whereas 140/90 mm Hg was used for elderly patients with low cardiovascular disease risk (44%) and for patients with chronic-phase stroke (27%). Answers to the questionnaire varied among physicians according to sex, age, workplace and specialty. The majority of the participating Japanese physicians were familiar with both JSH2004 and JSH2009, with many following the guidelines in their practice. However, some physicians use different reference values for hypertension and target BP levels. Physicians' adherence to and use of the guidelines should be regularly examined and promoted.

    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

    The Japanese Association for Acute Medicine (JAAM) disseminated intravascular coagulation (DIC) study group recently announced new diagnostic criteria for DIC. These criteria have been prospectively validated and demonstrated to progress to overt DIC as defined by the International Society on Thrombosis and Haemostasis (ISTH). Although an underlying condition is essential for the development of DIC, it has never been clarified if patients with different underlying disorders have a similar course. Among 329 patients with DIC diagnosed by the JAAM criteria, those with underlying sepsis (n = 98) or trauma (n = 95) were compared. The 28-day mortality rate was significantly higher in sepsis patients than trauma patients (34.7% vs. 10.5%, p < 0.0001). Within three days of fulfilling the JAAM criteria, sepsis patients had a lower platelet count, higher prothrombin time ratio, higher systemic inflammatory response syndrome score, and higher Sequential Organ Failure Assessment score compared with trauma patients. On day 3, a significantly higher percentage of trauma patients than sepsis patients showed improvement of DIC (64.2% vs. 30.6%, p < 0.001). These differences were mainly due to patients with lower JAAM DIC scores. More than 50% of the JAAM DIC patients with sepsis who died within 28 days could not be detected by ISTH DIC criteria during the initial three days. In contrast, most trauma patients who died within 28 days had DIC simultaneously diagnosed by JAAM and ISTH criteria, except for those with brain death. These findings suggest that coagulation abnormalities, organ dysfunction, and the outcome of JAAM DIC differ between patients with sepsis and trauma.

    Aims/Introduction This was a subanalysis of Japanese patients included in the glucagon-like peptide-1 receptor agonist AVE0010 in patients with type 2 diabetes mellitus for glycemic control and safety evaluation (GetGoal-S) study – a 24-week, randomized, placebo-controlled study of lixisenatide in patients with type 2 diabetes mellitus inadequately controlled by sulfonylurea with or without metformin. Materials and Methods In GetGoal-S, 127 Japanese patients received the once-daily prandial glucagon-like peptide-1 receptor agonist lixisenatide 20 μg/day or a matching placebo. The primary outcome was change in glycated hemoglobin. Results At week 24, lixisenatide significantly reduced mean glycated hemoglobin (least squares mean difference vs the placebo −1.1% [12 mmol/mol, P < 0.0001]), and significantly more lixisenatide patients reached glycated hemoglobin targets of <7% (53 mmol/mol) and ≤6.5% (48 mmol/mol) vs the placebo. Lixisenatide produced statistically significant reductions in 2-h postprandial plasma glucose (least squares mean difference vs the placebo −8.51 mmol/L, P < 0.0001) and glucose excursion vs the placebo, and significantly reduced fasting plasma glucose (least squares mean difference vs the placebo −0.65 mmol/L, P = 0.0454). Bodyweight decreased with both lixisenatide and the placebo (least squares mean change −1.12 kg for lixisenatide, −1.02 kg for placebo). The overall incidence of adverse events was similar for lixisenatide and the placebo (84.2 and 82.4%, respectively), the most frequent being gastrointestinal disorders (52.6% for lixisenatide vs 29.4% for placebo). The incidence of symptomatic hypoglycemia was higher with lixisenatide vs the placebo (17.1 and 9.8%, respectively), with no cases of severe symptomatic hypoglycemia in either group. Conclusions In the Japanese subpopulation of the GetGoal-S study, lixisenatide produced a significant and clinically relevant improvement in glycated hemoglobin, with

    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

    Objectives—To describe the sociodemographic profile of sports injury patients who attend sports medicine clinics for treatment and to describe their reasons for choosing to attend such clinics. Method—Data were collected as part of a fully audited injury surveillance system implemented within sports medicine clinics. The study was conducted within five allied multidisciplinary sports medicine clinics in metropolitan Melbourne, Australia. All patients initially presenting for treatment of a new sports or active recreation injury over the period August 1997 to August 1998 were eligible for this study, irrespective of the practitioner providing the treatment. Data were obtained on 6476 patients. Results—The median age of the patients was 25.4 years (range 6.8–81.6) and most were male (69.8% of cases; 95% confidence interval (95% CI) 68.7 to 70.9). Patients had both professional and non-professional backgrounds and were not just local suburb residents. Many patients had insurance cover for their injury treatment: 59.0% (95% CI 58.6 to 59.4) had some private health insurance and 46.6% (95% CI 45.4 to 47.8) had club/association insurance. The most common reasons for attending a clinic was its location (36.8%; 95% CI 36.5 to 37.1) and referral/recommendation (31.0%; 95% CI 30.7 to 31.3). Conclusion—Sports medicine clinics provide treatment for a broad spectrum of injured sports participants across a variety of sporting/recreation contexts. Although these clinics mainly serve the immediate geographic community, the sports speciality and expertise of a particular clinic can attract patients from further afield. This information can help sports medicine clinics to market their services more efficiently to meet the needs of their potential patients. Key Words: clinics; injuries PMID:11477021

    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.

    Diabetes mellitus with the mitochondrial DNA 3243(A-G) mutation is reported to represent 0.5-2.8% of the general diabetic population. Since the characterization of diabetes with the mutation is still incomplete, we undertook a nation-wide case-finding study of genetically defined patients using questionnaires in Japan. One hundred and thirteen Japanese diabetic patients with the mutation were registered and analyzed. The patients had a high prevalence of maternal inheritance of diabetes and deafness, short and thin stature, and showed an early middle-aged onset of diabetes and deafness. Eighty-six percent of the patients required insulin therapy due to the progressive insulin secretory defect. Glucose intolerance of the mothers was associated with an early middle-aged onset of diabetes, reduction in the insulin secretory capacity, early requirement of insulin therapy, and increases in the daily insulin dose. The heteroplasmic concentrations of the 3243 mutation in leukocytes were low and declined with aging. The patients had advanced microvascular complications, and mitochondria-related complications such as cardiomyopathy, cardiac conductance disorders, neuromuscular symptoms, neuropsychiatric disturbance, and macular pattern dystrophy. Thus, this study has revealed that: (1) diabetes mellitus with the 3243 mutation is a subtype of diabetes mellitus with mitochondria-related complications; and (2) insulin secretory ability is more severely impaired in the patients whose mothers were glucose intolerance.

    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

    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.

    The circumstances surrounding the certification examination for cytotechnologists in Japan are closely related with the history of the Japanese Society of Clinical Cytology. The examination for cytotechnologists is open only to medical technologists. The examination has two parts: primary and secondary. Qualification for candidacy for the secondary examination requires candidates to have passed the primary examination. The rate of successful applicants in the past 10 years was approximately 25-40%. Certified cytotechnologists are required to renew their qualifications every 4 years for their study and job history. I will present the purpose of the qualification update system, future themes, the reporting system for cytodiagnosis, and the possibility that the certification examination for cytotechnologists will become a national examination.

    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

    Stroke is regularly accompanied by dysphagia and other factors associated with decreased nutritional intake. Dysphagia with aspiration pneumonia and insufficient nutritional intake lead to worse outcome after stroke.This guideline is the first chapter of the guideline "Clinical Nutrition in Neurology" of the German Society for Clinical Nutrition (DGEM) which itself is one part of a comprehensive guideline about all areas of Clinical Nutrition. The thirty-one recommendations of the guideline are based on a systematic literature search and review, last updated December 31, 2011. All recommendations were discussed and consented at several consensus conferences with the entire DGEM guideline group. The recommendations underline the importance of an early screening and assessment of dysphagia and give advice for an evidence based and comprehensive nutritional management to avoid aspiration, malnutrition and dehydration.

    The relationship between chromosomal instability (CIN) and prognostic factors was investigated in 31 breast cancers and 5 benign breast lesions (three fibroadenomas and two papillomas). Using fluorescence in situ hybridization (FISH) with chromosome-specific DNA probes of chromosomes 1, 2, 6, 7, 10, 11, 17 and 18, CIN for each case was determined. CIN varied from 8.1% to 59.3% among the breast cancer patients tested, and was significantly higher than that observed in the benign breast lesions (p<0.01). Moreover, CIN showed a significant correlation with lymph node metastases (p<0.05) and estrogen receptor negativity (p<0.01). These findings suggest that CIN might be useful in the prediction of the biological aggressiveness of breast cancers. PMID:11412824

    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).

    The prevalence of fluoroquinolone-resistant Streptococcus pneumoniae is increasing worldwide. In the present study, a comparison of drug sensitivity and genotypes of clinically isolated strains of levofloxacin (LVFX)-resistant S. pneumoniae obtained from Hong Kong, Okinawa Island and the Japanese main island (Honshu) was performed. MICs of quinolones (LVFX, tosufloxacin, ciprofloxacin, gatifloxacin and sitafloxacin (STFX)) and other antibiotics (penicillin G, cefcapene, cefditoren, clarithromycin and azithromycin) were determined by a microdilution broth method according to the Clinical and Laboratory Standards Institute Standards. The quinolone-resistance determining regions (QRDRs) of gyrA, gyrB, parC and parE of these strains were analyzed by PCR-based sequencing. All 40 strains tested had more than one amino-acid substitution in the QRDRs of gyrA, gyrB, parC or parE. Although there seemed to be some clonality in strains obtained from Hong Kong, there was no clonality in strains obtained from Okinawa and Japan. Strains obtained from Hong Kong, Okinawa Island and the Japanese main island were genetically different by pulsed-field gel electrophoresis analysis. The range of MIC values of STFX against isolates resistant to LVFX (MIC 4-32 mg l(-1)) was 0.12-0.5 mg l(-1), and MIC(80) values of STFX against LVFX-resistant isolates were 0.25 mg l(-1). This study suggests that LVFX-resistant S. pneumoniae is similar in all three locations and STFX is potent against LVFX-resistant S. pneumoniae with multiple mutations in QRDRs of gyrase A and topoisomerase IV.

    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 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

    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

    The objective of this study was to comprehensively analyze the health-related quality of life (HRQOL) in Japanese patients with metastatic renal cell carcinoma (mRCC) during treatment with tyrosine kinase inhibitors (TKIs). This study included 240 Japanese mRCC patients treated with TKIs. We conducted a total of 305 surveys assessing the HRQOL before and 3 months after the introduction of TKIs, including 150, 95 and 60 during treatment with sorafenib, sunitinib and axitinib, respectively, using the Medical Outcomes Study 36-Item Short Form, consisting of eight multi-item scales measuring the health status. There were no significant differences in any of the eight scale scores between these 305 surveys conducted before and 3 months after TKI treatment. Two scores in the surveys during axitinib treatment were significantly superior to those during sorafenib treatment; however, no significant differences were noted in any of the remaining scale scores among the surveys during treatment with the three TKIs. Multivariate analyses, which were performed to evaluate the contribution of several factors to each scale score, revealed that the therapeutic efficacy had independent impacts on two scale scores, despite the lack of an independent association between any scores and the remaining factors, including the age, gender, introduced TKI, timing of TKI introduction and degree of adverse events. Collectively, these findings suggest that treatment with TKIs did not result in a significant impairment of the HRQOL in Japanese patients with mRCC; however, patients with unfavorable disease control appeared to fail to achieve a satisfactory HRQOL during treatment with TKIs.

    Acarbose, an α-glucosidase inhibitor, leads to the production of hydrogen gas, which reduces oxidative stress. In this study, we examined the effects of a single dose of acarbose immediately before a test meal on postprandial hydrogen gas in breath and peripheral blood interleukin (IL)-1β mRNA expression in Japanese type 2 diabetic patients. Sixteen Japanese patients (14 men, 2 women) participated in this study. The mean±standard deviation age, hemoglobin A1c and body mass index were 52.1±15.4 years, 10.2±2.0%, and 27.7±8.0kg/m(2), respectively. The patients were admitted into our hospital for 2 days and underwent test meals at breakfast without (day 1) or with acarbose (day 2). We performed continuous glucose monitoring and measured hydrogen gas levels in breath, and peripheral blood IL-1β mRNA levels before (0min) and after the test meal (hydrogen gas: 60, 120, 180, and 300min; IL-1β: 180min). The induction of hydrogen gas production and the reduction in peripheral blood IL-1β mRNA after the test meal were not significant between days 1 (without acarbose) and 2 (with acarbose). However, the changes in total hydrogen gas production from day 1 to day 2 were closely and inversely associated with the changes in peripheral blood IL-1β mRNA levels. Our results suggest that an increase in hydrogen gas production is inversely associated with a reduction of the peripheral blood IL-1β mRNA level after a single dose of acarbose in Japanese type 2 diabetic patients.

    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

    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

    The examination of an elderly patient often requires special techniques and attention to the patient's comfort and ease. This paper outlines a reasonable approach to each phase of the interview and discusses the particular medical problems of this age group. Older people are often slow to bring their troubles to medical attention because their symptoms are vague or because they accept their disability as part of old age. Sometimes they have difficulty in communicating effectively with the physician. Simple patience can ease an otherwise frustrating situation. PMID:7104901

    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.

    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.

    A questionnaire was used from 1972-1978 for 330 consecutive patients with recurrent urticaria of 3 months to 40 years duration. Fifty men and fifty women had only urticaria. The rest had both urticaria and angio-oedema and most of them were women between 24 and 38 years of age. Urticarial attacks were less frequent during the daytime. A personal history of rhinitis, asthma or atopic dermatitis was recorded in more than one-third. Nasal polyps, migraine and arthralgia were found in 6-7% of the patients. Severe psychiatric problems were mentioned by 16%. Abdominal problems, mainly gastritis, were described by 44%. A history of side effects from drugs was found in 32% of the patients. Food was mentioned as a factor worsening the weals by 30% and drinks by 18%. Fruits, vegetables and nuts were the most common. Despite all cases with physical urticaria having been excluded, physical factors such as exercise were considered by 20% to make the urticaria worse. Provocation tests with various food additives such as azo dyes, benzoates, butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA) sorbic acid, quinoline yellow, carotene, canthaxanthine, annatto and nitrite revealed one or more positive reactions in one-third of the patients, one-third showed negative provocation tests and, in the rest, one or several tests were questionable.

    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.

    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

    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.

    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

    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

    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

    A mass screening program for breast cancer in Japan consists of physical examination (PE) and education on regular breast self-examination (BSE). The effect of PE with BSE on clinical stages and courses of breast cancer patients were retrospectively analyzed. Clinical stages and courses were compared between; i) patients who were examined in outpatient clinics (OPC, n=587), ii) patients who were detected by mass screening with regular BSE [BSE(+), n=68], and iii) without BSE [BSE(-), n=178]. Clinical stage in BSE(+) was significantly earlier than that in BSE(-) or OPC. As early stage cancer was most common in BSE(+), conservative surgery was mostly selected. Survival curve in BSE(+) was significantly better than those in BSE(-) or OPC. BSE complements the role of mass screening by PE for early detection and a more favorable clinical course.

    Patients with cancer frequently suffer from insomnia symptoms, and additionally, their family members also often experience these symptoms. The aim of this study was to investigate the prevalence of insomnia symptoms in both family members and patients with hematological malignancies. We conducted an observational cross-sectional study using a clinical self-reported questionnaire for sleep conditions, depressive symptoms (two-question method), and worries (five items that originated from the Brief Cancer Worry Inventory). One hundred twelve family members and 153 patients were investigated. A t test and Chi-square test were used to compare the prevalence of insomnia and depressive symptoms between family members and patients. Logistic regression was used to determine whether insomnia symptoms or worries related to patients' disease had an impact on depressive symptoms. The presence of insomnia symptoms in family members (87 %) was significantly higher than that in patients (60 %, p < 0.001). The prevalence of depressive mood and anhedonia in family members were 55 and 34 %, respectively, and these values were higher than those in patients (43 and 28 %, respectively). Insomnia symptoms and worries about present/prospective disease conditions were significantly associated with depressive mood (insomnia symptoms, odds ratios (OR) 4.3, confidence intervals (CI) 1.2-15.2, p = 0.025; worries, OR 4.4, CI 1.0-19.3, p = 0.048). Taken together, our results demonstrated that insomnia symptoms and depressive symptoms are highly prevalent in family members as well as in patients with hematological malignancies. PMID:24947799

    Objectives Cognitive stimulation therapy (CST) has shown to have significant benefits in improving the cognitive function and quality of life (QOL) in people with mild-to-moderate dementia in a UK randomized controlled trial (RCT). We developed and examined the Japanese version of group CST (CST-J) in a single-blind, controlled clinical trial. Method CST-J consisting of 14 sessions was administered to a treatment group (n = 26) twice a week for 7 weeks. The treatment group was compared with a control group (n = 30). Based on single-blindness, cognition was evaluated by a researcher, and QOL and mood were rated by the participants themselves. Additionally, QOL and mood of participants were rated by care workers who were not blind but who observed them most directly in their daily life (important for social validity). Results A linear mixed model was used for analyses of cognition and QOL. There were significant improvements in cognition [COGNISTAT (Neurobehavioral Cognitive Status Examination) and MMSE (Mini-Mental State Examination)] for the treatment group compared with the control group (p < 0.01). Regarding QOL, the EQ-5D was significant (p = 0.019) and the QoL-AD (Quality of Life – Alzheimer's Disease) showed a positive trend (p = 0.06) when rated by care workers, although not when rated by the participants themselves. Using a nonparametrical analysis, there were significant improvements in the face scale for mood when rated by both the participants (p < 0.01) and the care workers (p = 0.017). Conclusion The CST-J shows promising improvements in cognition, mood, and aspects of QOL for people with dementia in Japanese care settings. A large RCT is now needed. PMID:23550665

  9. Efficacy of mirtazapine in clinically relevant subgroups of depressed patients.

    Mirtazapine is a noradrenergic and specific serotonergic antidepressant (NaSSA) with a novel mode of action that differs from other antidepressants that are currently available. Clinical trials have demonstrated it to have good antidepressant efficacy and excellent tolerability. Analysis of the results of placebo-controlled trials in moderately or severely depressed patients have shown mirtazapine to be effective in clinically important subgroups of depressed patients, particularly anxious patients, patients with sleep disturbance, retarded patients, and agitated patients. The efficacy and tolerability of mirtazapine are attributable to its pharmacological profile. It is likely that the overall antidepressant activity arises from its dual action, enhancing both noradrenergic and 5-HT1 receptor-mediated serotonergic neurotransmission, while the anxiolytic and sleep-improving properties of mirtazapine are attributable to the specific blockade of 5-HT2 and 5-HT3 receptors.

    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

    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.

    Japanese patients with uncontrolled essential hypertension received single-blind losartan 50 mg/hydrochlorothiazide 12.5 mg (L50/H12.5) for 8 weeks. Patients whose blood pressure (BP) remained uncontrolled were randomized double-blind to fixed-dose losartan 50 mg/hydrochlorothiazide 12.5 mg/amlodipine 5 mg (L50/H12.5/A5) or L50/H12.5 for 8 weeks followed by open-label L50/H12.5/A5 for 44 weeks. Adverse events were assessed. After 8 weeks, diastolic and systolic BP were reduced significantly more with L50/H12.5/A5 versus L50/H12.5 (both p < 0.001). Mean changes in diastolic and systolic BP were sustained for 44 weeks. L50/H12.5/A5 was well-tolerated and improved BP significantly versus L50/H12.5 in Japanese patients with uncontrolled essential hypertension.

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.

    Traffic accident is a leading cause of unintentional death and about six-thousands annually died in Japan. As about one-million of persons suffer from traffic injuries, most of them seek medical attention. Therefore, medical staffs have to find the injuries accurately and treat immediately. Furthermore, the cause of accident should also be considered; why the accident was occurred, human error of the driver? To solve these problems, clinical examinations were needed. Medical staffs have to understand the characteristics of the traffic injuries: severe and multiple blunt injuries, popular injuries can be estimated with considering the pattern of the accident. Because some of the accidents are occurred when the driver is under the influence of alcohol and other drugs, screening of these subjects should be performed. Because the public is largely unaware of the preventable nature of traffic injuries, in addition to diagnose and treat accurately, we medical staffs have to attend on the primary prevention of the traffic injuries.

    Nemaline myopathy (NM) is a rare congenital myopathy of great heterogeneity, characterized by the presence of rods in the cytoplasm of muscle fibers. This study aimed to summarize and analyze retrospectively the clinicopathological features of 28 patients with NM. Among the 28 patients, 15 were classified as of the typical congenital type, manifested as lower- or four-limb weakness as the first symptom and slowly progressive course. Six patients were classified as of childhood onset type, with lower-limb weakness and progressive course. Seven patients were classified as of the adult onset type, with rapidly progressive course and obvious muscle atrophy. Patient's 1, 16 and 23 had rapid clinical progression. On follow up, the three patients showed respiratory failure. Limb weakness in all patients was proximal‑dominant. Hypotonia was observed in most patients. High arched feet were also observed as dysmorfic features. In all patients, the creatine kinase (CK) level was normal or mildly elevated, and electromyography revealed myogenic changes. Nemaline bodies were observed under a light microscope in more than half of the patients' muscle fibers, and especially in type I fibers. All patients showed fiber type I predominance and atrophy. Modified Gömöri trichrome staining showed characteristic purple‑colored rods. Muscle electron microscopy revealed the presence of high electron‑dense nemaline bodies around the nucleus, and of a disorganized myofibrillar apparatus, with broken myofilaments and irregular myofibrils and Z lines. The 28 patients with NM shared a number of clinical features, such as proximal limb weakness, reduced deep tendon reflex and dysmorfic features. Differences were also observed between the three types of patients, with regards to course progression, disease severity and respiratory failure. In conclusion, patients with NM showed great clinical heterogeneity. The diagnosis of NM was mainly based on the muscle biopsy. PMID:24788569

  19. A Clinical Decision Support System for Breast Cancer Patients

    NASA Astrophysics Data System (ADS)

    Fernandes, Ana S.; Alves, Pedro; Jarman, Ian H.; Etchells, Terence A.; Fonseca, José M.; Lisboa, Paulo J. G.

    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.

    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.

    Purpose Studies of pregabalin for the treatment of central neuropathic pain have been limited to double-blind trials of 4–17 weeks in duration. The purpose of this study was to assess the long-term safety and tolerability of pregabalin in Japanese patients with central neuropathic pain. The efficacy of pregabalin was also assessed as a secondary measure. Patients and methods This was a 53-week, multicenter, open-label trial of pregabalin (150–600 mg/day) in Japanese patients with central neuropathic pain due to spinal cord injury, multiple sclerosis, or cerebral stroke. Results A total of 103 patients received pregabalin (post-stroke =60; spinal cord injury =38; and multiple sclerosis =5). A majority of patients (87.4%) experienced one or more treatment-related adverse events, most commonly somnolence, weight gain, dizziness, or peripheral edema. The adverse event profile was similar to that seen in other indications of pregabalin. Most treatment-related adverse events were mild (89.1%) or moderate (9.2%) in intensity. Pregabalin treatment improved total score, sensory pain, affective pain, visual analog scale (VAS), and present pain intensity scores on the Short-Form McGill Pain Questionnaire (SF-MPQ) and ten-item modified Brief Pain Inventory (mBPI-10) total score at endpoint compared with baseline. Improvements in SF-MPQ VAS and mBPI-10 total scores were evident in all patient subpopulations. Mean changes from baseline in SF-MPQ VAS and mBPI-10 scores at endpoint were −20.1 and −1.4, respectively. Conclusion These findings demonstrate that pregabalin is generally well tolerated and provides sustained efficacy over a 53-week treatment period in patients with chronic central neuropathic pain.

    Thalidomide is an important advance in the treatment of multiple myeloma. In Japan thalidomide is now on the approval step for the treatment of multiple myeloma. The drug has some bothersome side effects such as defect of organogenesis, neuropathy, constipation and fatigue, but is likely more effective than standard chemotherapy and is changing multiple myeloma treatment. At this moment, Japanese patients must import the thalidomide preparations from Mexico, Britain and elsewhere, but after approval, they patients will be able to get the new Japanese thalidomide capsules. In order to determine appropriate amounts of Japanese thalidomide capsules in the treatment of multiple myeloma, we compared the dissolution profile and plasma thalidomide concentrations of Japanese and British capsules and Mexican tablets. The dissolution test was performed according to the Japanese and the United States Pharmacopoeia. The pharmacokinetic data for Japanese capsules were obtained from the clinical trial in Japanese subjects and compared with those data published for other formulations. The dissolution rate of the Japanese capsule was the fastest, followed by British and Mexican formulations. The pharmacokinetic profiles of Japanese and British capsules were similar, while the 100 mg Japanese thalidomide capsule demonstrated a 1.6-fold higher maximum plasma concentration than the 200 mg Mexican thalidomide tablet (1.7 vs. 1.1 microg/ml), greatly shortened t(max) (4.5 vs. 6.2 h), and the apparent half life was only one-third of the Mexican tablet (4.8 vs. 13.5 h). A comparison of the dissolution and the pharmacokinetic absorption profiles demonstrated a rank-order correlation. Physicians and pharmacists should be aware of the probable alteration in plasma thalidomide concentration when switching to the Japanese capsule, especially from the Mexican tablet, and should monitor clinical response carefully.

  6. Safety and efficacy of long-term esomeprazole 20 mg in Japanese patients with a history of peptic ulcer receiving daily non-steroidal anti-inflammatory drugs

    PubMed Central

    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

    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.

    The objective was to assess the frequency of pure motor stroke caused by different stroke subtypes and to compare demographic, clinical, neuroimaging, and outcome data of pure motor stroke with those of patients with other lacunar stroke as well as with those of patients with non-lacunar stroke. Data from 2000 patients with acute stroke (n=1761) or transient ischaemic attack (n=239) admitted consecutively to the department of neurology of an acute care 350 bed teaching hospital were prospectively collected in the Sagrat Cor Hospital of Barcelona stroke registry over a 10 year period. For the purpose of the study 222 (12.7%) patients with pure motor stroke were selected. The other study groups included 218 (12.3%) patients with other lacunar strokes and 1321 (75%) patients with non-lacunar stroke. In relation to stroke subtype, lacunar infarcts were found in 189 (85%) patients, whereas ischaemic lacunar syndromes not due to lacunar infarcts occurred in 23 (10.4%) patients (atherothrombotic stroke in 12, cardioembolic stroke in seven, infarction of undetermined origin in three, and infarction of unusual aetiology in one) and haemorrhagic lacunar syndromes in 10 (4.5%). Patients with pure motor stroke showed a better outcome than patients with non-lacunar stroke with a significantly lower number of complications and in hospital mortality rate, shorter duration of hospital stay, and a higher number of symptom free patients at hospital discharge. After multivariate analysis, hypertension, diabetes, obesity, hyperlipidaemia, non-sudden stroke onset, internal capsule involvement, and pons topography seemed to be independent factors of pure motor stroke in patients with acute stroke. In conclusion, about one of every 10 patients with acute stroke had a pure motor stroke. Pure motor stroke was caused by a lacunar infarct in 85% of patients and by other stroke subtypes in 15%. Several clinical features are more frequent in patients with pure motor stroke than in patients

  9. Predictors of clinical pain intensity in patients with fibromyalgia syndrome.

    PubMed

    2004-08-01

    Central changes in pain processing have been previously reported in patients with fibromyalgia syndrome. These changes include decreased thresholds to mechanical and thermal stimuli (allodynia) and central sensitization, both of which are fundamental to the generation of clinical pain. Therefore, psychophysical measures of central pain processing may be useful predictors of clinical pain intensity of fibromyalgia syndrome patients. Previous studies of fibromyalgia syndrome patients have shown statistically significant correlations of psychophysical test results with clinical pain intensity. The tests used to characterize this important relationship were dependent on spinal cord pain mechanisms and included temporal summation of pain or wind-up and wind-up after-sensations. Particularly, the magnitude of wind-up after-sensations appeared to be one of the best predictors for clinical pain intensity of fibromyalgia syndrome patients (27%). Furthermore, the combination of tender point count, negative affect, and wind-up after-sensations accounted for approximately 50% of the variance in clinical pain intensity of fibromyalgia syndrome patients. Therefore, wind-up after-sensations, tender point count, and negative affect not only seem to represent relevant pain mechanisms but also strongly emphasize their importance for fibromyalgia syndrome pain.

    SUMMARY The Molar Incisor Hypomineralization (MIH) is a qualitative and quantitative defect of the enamel structure of the first permanent molars, which may vary from 1 to 4 with involvement of maxillary and jaw permanent incisors. Aim. Aim of this study is that to evaluate, among 1500 paediatric patients chosen at random aged between 0 and 14 years, afferent by the Paediatric Dentistry of the Azienda Ospedialiera Policlinico Tor Vergata of Rome from 1996 to 2011, the incidents and the prevalence of the MIH distribution, and furthermore to ascertain the possible relationship with the data described in the literature. Results and discussion. From the sample of 1500 paediatric patients, the number of those affections from MIH has turned out to be pairs to 110 (7.3%) aged between 4 and 15 years, and an average age equal to 9.7. The incidence of the hypoplastic defects is greater in the elements of the permanents series in which the functional class mainly interested is that of the first molars, with a percentage of 39.8%. Regarding the elements of the deciduous series affections from hypoplasia, they turn out to be in all in number of 20 represented in 80% of the cases from the seconds molars while in the remaining 20% of the cases the items involved are the central incisors. About the percentage of elements involved in the MIH: the molars, involved with a frequency of 56%, turn out to be more hit regarding incisors (44%). As reported in the literature, it can be asserted that the MIH can hit in equal measure both the male sex that feminine one. Conclusions. MIH represents a condition quite frequent in the paediatric population. In managing this anomaly takes an essential role in the early diagnosis and in the differential one. The study done underlined the importance of a correct application of the therapeutic protocol which, starting from a careful diagnosis and articulating themselves in the execution of preventive treatments and in severe cases restorative and

    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

    Movement disorders (bemichorea-hemiballismus, hemidystonia and isolated tremor) are an uncommon clinical manifestation in ischemic stroke (IS), and their anatomical basis is poorly understood. We analyzed the clinical and neuroimaging characteristics of 22 consecutive patients who bad movement disorders associated with cerebral infarction (MDCI), studied at four institutions over 8 years. In one institution (from the La Alianza-Central Hospital of Barcelona Stroke Registry) nine patients with MDCI were identified among 1099 consecutive first ever stroke patients (0.8%) (908 with IS, 1%). Fifteen out of 22 patients (68%) had hemichorea-hemiballismus, five (23%) hemidystonia and two (9%) isolated tremor. MDCI were more often left sided (n = 15, 68%), being bilateral in one patient (4.5%). A lesion was found on neuroimaging (CT and/or MRI) in 15 patients (68%), in the territory of the posterior cerebral artery (n = 8) and middle cerebral artery (six deep and one superficial). The most commonly involved structure was the thalamus (n = 8, 36.5%). IS subtypes were; presumed lacunar infarcts in 14 patients (64%), atherothrombotic infarcts in two patients (9%), cardioembolic infarcts in two patients (9%) and infarcts of unknown etiology in four patients (18%). Hemichorea-hemiballismus was the most common type of MDCI in our study, usually being the result of a thalamic infarction. The thalamus was the most frequently damaged structure underlying all types of MDCI. There was a striking propensity of MDCI which resulted from nondominant deep hemispheric small vessel infarctions.

    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

    Vulval Crohn's disease [VCD] is a challenging condition that can occur without gastrointestinal Crohn's disease [GCD]. We reviewed the clinical features and effects of therapy in a cohort of 22 patients with VCD to determine whether the presence of GCD affected the clinical presentation and treatment response. Of these, 64% had GCD and 65% of these presented with GCD prior to VCD. Fissuring, ulceration, and scarring were more common in those with VCD alone. Potent and ultra-potent topical steroids showed benefit in most patients. There was no clear evidence of sustained remission with metronidazole. Azathioprine was the most commonly used oral immunosuppressive agent, with an efficacy of 57%. Patients with both VCD and GCD had a better clinical response compared with those with VCD alone [70% and 25%, respectively]. Infliximab and adalimumab were effective in 56% and 71% of patients, respectively. Excision of redundant tissue was helpful in four patients. The absence of GCD may delay the diagnosis in women who present with vulval symptoms alone. The more active clinical features in those with VCD alone may represent a more aggressive condition, or the severity of the cutaneous disease may have been reduced by immunosuppression taken for GCD. Several patients obtained sustained remission in their GCD with anti-tumor necrosis factor alpha [anti-TNFα] agents while the VCD remained active.

    2002-09-01

    Bioethicists have articulated an ideal of shared decision making between physician and patient, but in doing so the role of clinical uncertainty has not been adequately confronted. In the face of uncertainty about the patient's prognosis and the best course of treatment, many physicians revert to a model of nondisclosure and nondiscussion, thus closing off opportunities for shared decision making. Empirical studies suggest that physicians find it more difficult to adhere to norms of disclosure in situations where there is substantial uncertainty. They may be concerned that acknowledging their own uncertainty will undermine patient trust and create additional confusion and anxiety for the patient. We argue, in contrast, that effective disclosure will protect patient trust in the long run and that patients can manage information about uncertainty. In situations where there is substantial uncertainty, extra vigilance is required to ensure that patients are given the tools and information they need to participate in cooperative decision making about their care.

    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

    This study evaluated patients' understanding of common terms used by breast surgeons in order to identify words which may need to be defined and explained during a clinic consultation. 95 patients completed the survey. 87% defined 'Surgeon' correctly whereas 'Radiographer' and 'Radiologist' were correctly defined by only 19% and 28% respectively. 26% correctly defined 'Pathologist' and 43% 'Oncologist'. Two-thirds of patients correctly defined 'Benign' (66%) and 'Malignant' (65%). 'Mammogram' and 'Ultrasound' were correctly defined by 39% and 8% respectively. 21% of patients correctly defined 'Multi-Disciplinary Team Meeting'. 1 in 5 patients correctly defined 'Chemotherapy' (20%) and 'Radiotherapy' (19%). This study has identified that many of the medical terms used in a consultation are not understood by patients. Education must be incorporated as a routine part of the consultation to enhance the patient experience and ensure they can actively participate in making informed decisions about their care.

    This study was performed to investigate the pharmacokinetics of valaciclovir (VACV), aciclovir (ACV) and 9-(carboxymethoxy)methylguanine (CMMG) in Japanese chronic hemodialysis patients following a single oral administration of 1000 mg VACV and the influence of genetic polymorphisms of aldehyde dehydrogenase-2 (ALDH2) on their pharmacokinetics. A total of eighteen individuals genotyped as ALDH2*1/*1, ALDH2*1/*2 or ALDH2*2/*2 were enrolled in this study. Blood samples were obtained pre-dose and up to 48 hour post-dose. ACV t(1/2) was significantly affected by ALDH2 genotype and prolonged in the order of ALDH2*1/*1 (18.1 hr)Japanese end-stage renal disease patients.

    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

    Acute myeloid leukemia (AML) is a disease diagnosed mostly in patients >65 years of age. Despite its heterogeneous nature, the different types of AMLs are still managed by standard induction chemotherapy for those who can tolerate it in the beginning. For the elderly and infirm patients, however, this approach leads to unacceptably high induction mortality rate. This article reviews past and current efforts searching for low-intensiveness treatments for the elderly and infirm patients who cannot tolerate the standard induction regimen. Volasertib, currently in Phase III clinical trials in combination with cytarabine, is reviewed as a promising agent for this patient population with AML, from the viewpoints of potential compliance and efficacy.

    No clinical laboratory would admit they do not practice team medicine, at least conceptually. However, true team medicine is more than an aspiration--it is an intentional care structure built, led, and delivered by a diverse, multidisciplinary team of physicians, medical technologists, nurses, pharmacists, and dozens of other professionals. We clinical laboratory physicians are able to fulfill an important role as competent members of the team medicine. Because we can look at the results of clinical examinations of patients earlier than anyone else, we can interpret the patient's condition by analyzing that results, and provide useful information to facilitate team medicine. I have conducted a questionnaire survey on team medicine targeting clinical laboratory physicians to clarify the tasks we are performing. In this paper, I describe what clinical laboratory physicians are currently doing, and how should we develop in the future.

    Role-play techniques can serve as an effective substitute for, and supplement to, simulation technology when teaching clinical nursing skills. They provide risk-free opportunities to practice clinical skills and develop clinical judgment. A two-phase patient care simulation, performed in real time, is described. Students are presented with a scenario and work cooperatively in role-playing appropriate care, with one student using a prepared script to assume the role of patient. The class functions as a resource for four students who assume the nursing role. Students reported increased understanding of course material as a result of participation in the clinical simulation scenario. Faculty observed a decreased failure rate on the corresponding course examination.

    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

    Keishibukuryogan (KBG; Guizhi-Fuling-Wan in Chinese) is one of the Kampo (Japanese traditional) medicines used to treat patients with climacteric syndrome. KBG can be used by patients who cannot undergo hormone replacement therapy due to a history of breast cancer. We evaluated whether cytosine-adenine (CA) repeat polymorphism of the estrogen receptor β gene can be a predictor of the beneficial effect of KBG on climacteric syndrome. We also investigated the relationship between CA repeat polymorphism, the patients' profiles, and the therapeutic effect. We found that CA was an SS, SL, or LL genotype according to the number of repeats. We studied 39 consecutive patients with climacteric disorders who took KBG for 12 weeks. The diagnosis of climacteric disorders was made on the basis of the Kupperman index. KBG significantly improved the patients' climacteric symptoms (i.e., vasomotor symptoms in the patients with the LL genotype and melancholia in the patients with the SL genotype). No relationship between the patients' profiles and CA repeat polymorphism was recognized. CA repeat polymorphism could thus be a potential biomarker to predict the efficacy of KBG in climacteric syndrome, and its use will help to reduce the cost of treating this syndrome by focusing the administration of KBG on those most likely to benefit from it.

    GIFT‐I is a phase 3 trial evaluating the efficacy and safety of a 12‐week regimen of coformulated ombitasvir (OBV)/paritaprevir (PTV)/ritonavir (r) for treatment of Japanese hepatitis C virus genotype 1b–infected patients. It consists of a double‐blind, placebo‐controlled substudy of patients without cirrhosis and an open‐label substudy of patients with compensated cirrhosis. Patients without cirrhosis were randomized 2:1 to once‐daily OBV/PTV/r (25 mg/150 mg/100 mg; group A) or placebo (group B). Patients with cirrhosis received open‐label OBV/PTV/r (group C). The primary efficacy endpoint was the rate of sustained virological response 12 weeks posttreatment in interferon‐eligible, treatment‐naive patients without cirrhosis and hepatitis C virus RNA ≥100,000 IU/mL in group A. A total of 321 patients without cirrhosis were randomized and dosed with double‐blind study drug (106 received double‐blind placebo and later received open‐label OBV/PTV/r), and 42 patients with cirrhosis were enrolled and dosed with open‐label OBV/PTV/r. In the primary efficacy population, the rate of sustained virological response 12 weeks posttreatment was 94.6% (106/112, 95% confidence interval 90.5‐98.8). Sustained virological response 12 weeks posttreatment rates were 94.9% (204/215) in group A, 98.1% (104/106) in group B (open‐label), and 90.5% (38/42) in group C. Overall, virological failure occurred in 3.0% (11/363) of patients who received OBV/PTV/r. The rate of discontinuation due to adverse events was 0%‐2.4% in the three patient groups receiving OBV/PTV/r. The most frequent adverse event in patients in any group was nasopharyngitis. Conclusion: In this broad hepatitis C virus genotype 1b–infected Japanese patient population with or without cirrhosis, treatment with OBV/PTV/r for 12 weeks was highly effective and demonstrated a favorable safety profile.

    AIM: To evaluate the frequency, clinical and paraclinical features of hepatopulmonary syndrome (HPS) and to determine their predictive values in diagnosis of this syndrome in patients in Iran. METHODS: Fifty four cirrhotic patients underwent contrast enhanced echocardiography to detect intrapulmonary and intracardiac shunts by two cardiologists. Arterial blood oxygen, O2 gradient (A-a) and orthodoxy were measured by arterial blood gas (ABG) test. The patients positive for diagnostic criteria of HPS were defined as clinical HPS cases and those manifesting the intrapulmonary arterial dilation but no other criteria (arterial blood hypoxemia) were defined as lHPS cases. HPS frequency, sensitivity, positive and negative predictive values of clinical and paraclinical features were studied. RESULTS: Ten (18.5%) and seven (13%) cases had clinical and subclinical HPS, respectively. The most common etiology was hepatitis B. Dyspnea (100%) and cyanosis (90%) were the most prevalent clinical features. Dyspnea and clubbing were the most sensitive and specific clinical features respectively. No significant relationship was found between HPS and splenomegaly, ascites, edema, jaundice, oliguria, and collateral veins. HPS was more prevalent in hepatitis B. PaO2 < 70 and arterial-alveolar gradient had the highest sensitivity in HPS patients. Orthodoxy specificity was 100%. CONCLUSION: Clubbing with positive predictive value (PPV) of 75% and dyspnea with negative predictive value (NPV) of 75% are the best clinical factors in diagnosis of HPS syndrome. PaO2 < 70 and P (A-a) O2 > 30 and their sum, are the most valuable negative and positive predictive values in HPS patients. PMID:16610006

    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.

    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.

    Participation in clinical trials remains low and is a central issue in oncology. The authors identified, through a systematic review, 75 papers published up to August 2004 that report barriers to recruitment of patients in clinical trials. These barriers range from patient preference and concern about information/consent to clinical problems with protocols. Strategies to overcome barriers on the part of patients and clinicians are needed and should be carefully evaluated. Thirty-three (44%) papers reported factors related to patients as influencing the inclusion of patients, 28 (37%) reported clinician's related factors, and 37 (49%) other factors from either specific groups of patients (30 papers, 40%) and/or other scopes (13 papers, 17%). No differences in prevalence were found between papers dedicated to hematologic malignancies and solid tumors. Factors related to clinicians as influential were more frequently reported before 1995 (70%) than thereafter (25%; P = 0.0009). Reporting specific groups of patients as influential was more frequent in North American articles (50%) than in others (14%, P = 0.008). Patients' barriers included mostly patient preference (12 papers), concern about information and/or consent (11 papers), worry about uncertainty (7 papers), and/or relationship with medical team (7 papers). Concerning clinicians, incompatibility of protocol with normal practice (nine papers), problems in complying with the protocol (eight papers), and/or consent procedure (eight papers) were the most reported factors. The remaining factors mostly relied on specific groups of patients (30 papers), notably age of patients (18 papers) and/or minority population (11 papers, all from the USA). Strategies to overcome these barriers are needed and should be carefully evaluated. PMID:16397866

    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.

    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.

    We evaluated the reliability of scaled and binary clinical judgements of insight. Twelve clinicians rated 30 DVD interview recordings of patients diagnosed with a psychotic disorder. Scaled ratings produced an ICC of 0.62. Reliability of categorical (binary) ratings was 0.37 (k). While ordinal ratings are more reliable than binary ratings, reliability across both methods is too low for important decision-making. Clinical judgements of insight are impaired by a lack of standardised diagnostic criteria. PMID:23643189

    Relatively little attention has been focused on standardization of data exchange in clinical research studies and patient care activities. Both are usually managed locally using separate and generally incompatible data systems at individual hospitals or clinics. In the past decade there have been nascent efforts to create data standards for clinical research and patient care data, and to some extent these are helpful in providing a degree of uniformity. Nevertheless these data standards generally have not been converted into accepted computer-based language structures that could permit reliable data exchange across computer networks. The National Cardiovascular Research Infrastructure (NCRI) project was initiated with a major objective of creating a model framework for standard data exchange in all clinical research, clinical registry, and patient care environments, including all electronic health records. The goal is complete syntactic and semantic interoperability. A Data Standards Workgroup was established to create or identify and then harmonize clinical definitions for a base set of standardized cardiovascular data elements that could be used in this network infrastructure. Recognizing the need for continuity with prior efforts, the Workgroup examined existing data standards sources. A basic set of 353 elements was selected. The NCRI staff then collaborated with the two major technical standards organizations in healthcare, the Clinical Data Interchange Standards Consortium and Health Level 7 International, as well as with staff from the National Cancer Institute Enterprise Vocabulary Services. Modeling and mapping were performed to represent (instantiate) the data elements in appropriate technical computer language structures for endorsement as an accepted data standard for public access and use. Fully implemented, these elements will facilitate clinical research, registry reporting, administrative reporting and regulatory compliance, and patient care. PMID

    In order to define the possibilities and approaches to the humanization and democratization of labour rehabilitation of mental patients, to reveal and consider individual requirements constituting each patient's personality, a study was made of the motives of attending the treatment and industrial shops (TIS) by them and preferable types of labour activities. Use was made of special formalized maps devised for the given study purposes. All the possible motives of attending TIS and preferable labour activities were registered in those maps as was an objective assessment of the output per man-hour. 221 patients were examined. The results of the examination were assessed in accordance with distribution of the patients by the clinical parameters. The hierarchy of the motives and preferences and output per man-hour depended on the patients' clinical characteristics. Still, it has been established on the whole that attending TIS, 91% were willing to work, 85% to change the environment, 70% to speed up the discharge, 65% to enhance the treatment efficacy, 45% to communicate with new people, 33% to earn money. 46% of the patients reported to work passively, under the influence of persuasions. 71% preferred performing collective work, 68% unsophisticated, 63% very simple work without any responsibility, 53% mobile, 51% sedentary, 49% physical, 32% complicated, 25% individual, 7% intellectual. Only 85% of the patients attending TIS worked. The highest productivity was recorded in patients with borderline mental disorders, the lowest in patients with actual psychotic disorders.

    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.

    The development of a patient-centered approach to medicine is gradually allowing more patients to be involved in their own medical decisions. However, this change is not happening at the same rate in clinical research, where research generally continues to be carried out on patients, but not with patients. This work describes the why, when, and how of more active patient participation in the research process. Specific measures are proposed to improve patient involvement in 1) setting priorities, 2) study leadership and design, 3) improved access to clinical trials, 4) preparation and oversight of the information provided to participants, 5) post-study evaluation of the patient experience, and 6) the dissemination and application of results. 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.

    Food hypersensitivity (FH) is lesser frequent among adult patients than in childhood. Foods implicated in hypersensitivity reactions vary with sociocultural and diet habits from a geographic place to other. We studied 142 adult patients sensitized to foods, among 7698 patients visited at our Outpatient Clinic. Hundred and twenty patients referred clinical symptoms after consumption of one or more foods consistently. From the latest, 107 patients (89.2%) were atopics (92 of them sensitizes to dust mites) and 54 (45%) referred atopic familiar background. Most frequent recorded symptoms were: urticaria/angioedema 84 cases (70%), oral syndrome 65 (54%), asthma 48 (37%) and anaphylaxis 33 patients (27.5%). Shellfish sensitization occurred in 50 patients, fresh fruits in 33 and nuts in 29 cases. Shrimp (48 patients), squid (33), kiwi (14), papaya (14), avocado (13) and banana (12 cases) were the most frequent causes of FH. Significant statistical association between foods and inhalants was observed for fresh fruits and latex (p < 0.001), fresh fruits and pollens (p < 0.01), and shellfish and Blatta germanica (p < 0.001). Prevalence of FH among patients at our Area is around 1.6%. Tropical fruits, as other kind of fruits, seem to share common IgE-epitopes to pollens. High prevalence of shellfish and cockroach hypersensitivity could be more easily developed by previous domestic mites sensitization.

    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

    Transient epileptic amnesia is a seizure disorder, usually with onset in the middle-elderly and good response to low dosages of antiepileptic drugs. We describe the clinical, electroencephalography (EEG), and neuroimaging features of 11 patients with a temporal lobe epilepsy characterized by amnesic seizures as the sole or the main symptom. We outline the relevance of a detailed clinical history to recognize amnesic seizures and to avoid the more frequent misdiagnoses. Moreover, the response to monotherapy was usually good, although the epileptic disorder was symptomatic of acquired lesions in the majority of patients.

    Hemifacial spasm (HFS) is a common neurological disorder characterized by involuntary tonic and clonic contractions of the muscles innervated by the facial nerve. We aimed to describe clinical features, common antecedents, triggers and relieving factors in patients with hemifacial spasm to study the correlation of hypertension and HFS, and to compare clinical features of primary and secondary cases of HFS. The data for the study were collected prospectively on a predesigned and pre-tested format at the first attendance in all consecutive HFS patients attending the movement disorders clinic of a tertiary teaching hospital in India. The demographic profile, HFS symptoms, antecedent illnesses and neurological examination were recorded and analyzed. Muscle power in individual muscles innervated by the facial nerve was tested carefully before botulinum toxin injection. Hemifacial spasm occurred in 7.14% (n = 582) of 8,151 cases registered at the movement disorders clinic from 1993 to 2010. Data of 321 patients were complete and were included in the study. Females constituted 49.22% (n = 158). The mean age the patients was 46.02 ± 11.82 years; ipsilateral ear clicking was observed in 22.74% cases. The most common aggravating factor was stress (44.86%), while the most common relieving factor was sleep (44.24%). Two hundred fifty-two patients (78.5%) had primary HFS. The severity of spasm correlated significantly with disease duration (p < 0.001) and weakness of facial muscles (p < 0.001). We did not observe any correlation between HFS on the left side and hypertension, as has been reported earlier. This is one of the largest studies of HFS patients and the only one that prospectively assesses patients with HFS clinically on their first visit. Interesting observations of this study are lack of female preponderance, presence of clicking in the ipsilateral ear and facial weakness even prior to botulinum toxin injection.

  3. Risk bodies: rehabilitation of sports patients in the physiotherapy clinic.

    This paper describes how body regimes are effectuated in the prevailing treatment strategy of physiotherapy. The process of self-mastering in the context of sports-related injuries is highlighted. Through a Foucauldian perspective on body regimes the aim is to shed light on the process of individualization and self-mastery in rehabilitation. The treatment of illness in the physiotherapy clinic does not characterize the patient as sick, and exempt the patient from daily duties and expectations. The empirical data include 17 qualitative illness narratives and several years of fieldwork observing patients with anterior cruciate ligament (ACL) injuries in a physiotherapy clinic. The study demonstrates how the expectation that the patients be active and self-mastering permeates the total process of treatment. The individual responsibility for personal well-being is a recurrent phenomenon in public health services in general, and specifically prominent in the rehabilitation of sports injuries.

    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

    Clinical molecular imaging by use of PET and PET/CT is increasingly important in routine oncological practice worldwide. A vast majority of clinical PET investigations are performed with [18F]-fluorodeoxyglucose (FDG), but there is a growing interest in novel molecular probes among scientists and clinicians. Beyond FDG, a small number of different tracers have been shown to be of clinical value. With a growing commercial interest in tracer development, many more are under investigation. This review provides some examples of clinical situations where tracers other than FDG have been found useful and an outlook towards technical and regulatory development needed to allow the full impact of clinical PET to benefit the individual patient.

    Recognizing that established relationships enhance understanding and therefore improve clinical intuition and inference, the authors examined clinical and legal characteristics of a legally and clinically heterogeneous population of maximum security forensic hospital patients (n = 380). Several findings serve to substantiate outcomes of previous studies of subgroups of offenders. Some new relationships among legal and clinical variables are established. The relationship between admission legal status and Axis I diagnosis is dependent upon the Axis II diagnosis. Those admitted for competency evaluations have the lowest percentage of psychotic diagnoses and the highest IQ. Kidnapers have the highest percentage of psychotic diagnoses and there is a relationship between previous incarceration and drug treatment refusal. The authors discuss clinical implications, generalizability, and the needs for further investigation.

    A phase IV, multicentre, randomized, double-blind, parallel-group, comparative study was conducted in Japanese subjects with type 2 diabetes mellitus (T2DM) who had inadequate glycaemic control, despite treatment with alogliptin in addition to diet and/or exercise therapy. Subjects with glycated haemoglobin (HbA1c) concentrations of 6.9-10.5% were randomized to receive 16 weeks' double-blind treatment with pioglitazone 15 mg, 30 mg once daily or placebo added to alogliptin 25 mg once daily. The primary endpoint was the change in HbA1c from baseline at the end of treatment period (week 16). Both pioglitazone 15 and 30 mg combination therapy resulted in a significantly greater reduction in HbA1c than alogliptin monotherapy [-0.80 and -0.90% vs 0.00% (the least squares mean using analysis of covariance model); p < 0.0001, respectively]. The overall incidence rates of treatment-emergent adverse events were similar among the treatment groups. Pioglitazone/alogliptin combination therapy was effective and generally well tolerated in Japanese subjects with T2DM and is considered to be useful in clinical settings.

    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.

    The aim of the study was to evaluate the efficacy and safety of once-daily lixisenatide 20 μg as add-on to basal insulin with or without sulfonylurea in Asian patients with type 2 diabetes mellitus. The study as a subanalysis of the 159 Japanese patients from the 24-week double-blind GetGoal-L-Asia study (NCT00866658) who received once-daily lixisenatide or placebo. The primary endpoint was change from baseline in HbA1c evaluated using analysis of covariance. Once-daily lixisenatide significantly reduced mean HbA1c [least squares mean difference vs. placebo - 1.1% (- 12 mmol/mol); p<0.0001]. Significantly more patients in the lixisenatide group reached HbA1c targets of < 7% (53 mmol/mol; 31.4 vs. 2.3% for placebo; p<0.0001) and ≤ 6.5% (48 mmol/mol; 12.9 vs. 1.2% for placebo; p=0.0028). Lixisenatide significantly reduced 2-h postprandial plasma glucose (least squares mean difference vs. placebo-8.64 mmol/l; p<0.0001), glucose excursion (least squares mean difference vs. placebo - 7.80 mmol/l; p<0.0001) and fasting plasma glucose (least squares mean difference vs. placebo - 0.96 mmol/l; p=0.0126). Body weight was reduced with lixisenatide but with no significant difference vs. placebo. Gastrointestinal adverse events were more frequent with lixisenatide (61.1 vs. 11.5% for placebo) but were generally transient and mild-to-moderate in intensity. The incidence of symptomatic hypoglycemia was 39.0 vs. 13.5% in patients receiving sulfonylureas and 32.3 vs. 22.9% in those not receiving sulfonylureas, for lixisenatide and placebo, respectively. In Japanese patients with type 2 diabetes mellitus, once-daily lixisenatide was well tolerated and led to significant and clinically relevant improvement in glycemic control, with a pronounced effect on postprandial plasma glucose.

    The reestablishment of communication is one of the main goals for patients with disorders of consciousness (DOC). It is now established that many DOC patients retain the ability to process stimuli of varying complexity even in the absence of behavioural response. Motor impairment, fatigue, attention disorders might contribute to the difficulty of communication in this population. Brain-computer interfaces (BCI) might be helpful in restoring some communication ability in these patients. After a definition of the different disorders of consciousness that might benefit from BCI, brain markers able to detect cognitive processes and awareness in the absence of behavioural manifestation are described. Can these markers be willfully modulated and used to restore communication in DOC patients? In order to answer this question, three paradigmatic articles using either functional imaging or electrophysiology are critically analysed with regard to clinical applications. It appears that the use of fMRI is limited from a clinical point of view, whereas the EEG seems more feasible with possible BCI applications at the patient's bedside. However, at this stage, several limitations are pointed out: the lack of awareness in itself, the lack of sensitivity of the technique, atypical pattern of brain activity in brain damaged patients. The challenge is now to select the best candidates, to improve the efficiency, portability and cost of these techniques. Although this innovative technology may concern a minority of DOC patients, it might offer the possibility to restore or improve communication to heavily disabled patients and meanwhile detect a signature of awareness.

    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.

    Lacunar infarcts in non-hypertensive patients have been scantly assessed. The objective of this study was to determine clinical features of lacunar infarct in patients without hypertension (n = 91) in comparison with characteristics of lacunar infarcts occurring in patients with hypertension (n = 283) collected from a prospective hospital-based stroke registry in which 2000 patients with acute stroke are included. Predictors of lacunar infarct in patients without hypertension were assessed by multiple logistic regression analysis. The group of non-hypertensive patients with lacunar infarction showed a significantly higher frequency of male gender, age 85 years or older, history of atrial fibrillation, chronic obstructive pulmonary disease and diabetes mellitus, and a significantly lower frequency of female gender and absence of limitation at hospital discharge than hypertensive patients with lacunar infarct. Differences between hypertensive and non-hypertensive patients in relation to frequency of the different lacunar syndromes were not observed. After multivariate analysis, age 85 years or older (odds ratio 3.13), diabetes (odds ratio 2.57), and male gender (odds ratio 1.99) seemed to be independent factors associated with lacunar infarct in patients without hypertension. Lacunar infarct in non-hypertensive patients showed some differential clinical features compared to the remaining lacunar infarctions because it occurred more frequently in male patients aged 85 years or older. In this group, diabetes was the most important modifiable risk factor. These results suggest an earlier effect of arteriopathy caused by hypertension favoring lacunar brain ischemia, whereas in non-hypertensive patients, arteriopathy responsible for small vessel disease would take a more prolonged time in causing lacunar infarction.

    Purpose To compare pulmonary and systemic inflammatory mediator release, pre- and poststimulation, ex vivo, in cells from Japanese patients with chronic obstructive pulmonary disease (COPD), non-COPD smoking controls, and non-COPD nonsmoking controls (NSC). Patients and methods This was a nontreatment study with ten subjects per group. Inflammatory biomarker release, including interleukin (IL)-6 and -8, matrix metalloproteinase-9, and tumor necrosis factor (TNF)-α, was measured in peripheral blood mononuclear cells (PBMC) and sputum cells with and without lipopolysaccharide or TNF-α stimulation. Results In PBMC, basal TNF-α release (mean ± standard deviation) was significantly different between COPD (81.6±111.4 pg/mL) and nonsmoking controls (9.5±5.2 pg/mL) (P<0.05). No other significant differences were observed. Poststimulation biomarker release tended to increase, with the greatest changes in the COPD group. The greatest mean increases were seen in the lipopolysaccharide-induced release of matrix metalloproteinase-9, TNF-α, and IL-6 from PBMC. Pre- and poststimulation data from sputum samples were more variable and less conclusive than from PBMC. In the COPD group, induced sputum neutrophil levels were higher and macrophage levels were lower than in either control group. Significant correlations were seen between the number of sputum cells (macrophages and neutrophils) and biomarker levels (IL-8, IL-6, and TNF-α). Conclusion This was the first study to compare cellular inflammatory mediator release before and after stimulation among Japanese COPD, smoking controls, and nonsmoking controls populations. Poststimulation levels tended to be higher in patients with COPD. The results suggest that PBMC are already preactivated in the circulation in COPD patients. This provides further evidence that COPD is a multicomponent disease, involving both airway and systemic inflammation. PMID:26929615

    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

    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

    It is still unclear as to how cardiorespiratory fitness and visceral fat accumulation contribute to coronary heart disease (CHD) risk factors in patients with diabetes mellitus. The purpose of the present study was to investigate whether cardiorespiratory fitness contributes to such risk factors independently of visceral fat accumulation. Two hundred Japanese patients (137 men and 63 women, aged 22 to 81 years) with impaired glucose tolerance (IGT) and type 2 diabetes mellitus (type 2 DM) without any intervention and pharmacological therapy participated in a cross-sectional study. The levels of fasting insulin, triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and resting blood pressure were assessed. Maximal oxygen uptake (V.o(2max)), an index of cardiorespiratory fitness, was predicted by a graded exercise test using a cycle ergometer. Visceral fat area (VFA) was measured by computed tomography scan. The criteria for abnormalities of the risk factors were determined according to the standard values for Japanese. All subjects were divided equally into the following 3 groups according to their fitness level: low-fit (V.o(2max) < 32 mL/kg/min in men, V.o(2max) < 26 mL/kg/min in women), mid-fit (32 < or = V.o(2max) < 36 in men, 26 < or = V.o(2max) < 30 in women), and high-fit (V.o(2max) > or = 36 in men, V.o(2max) > or = 30 in women). The association between fitness level and the prevalence of abnormal values for these parameters was analyzed by a multiple logistic regression model adjusted for age and VFA. The odds ratio (OR) and 95% confidence interval (CI) for the prevalence of hyperinsulinemia were significantly lower in the mid-fit (OR = 0.35, 95% CI, 0.16 to 0.78) and in the high-fit groups (OR = 0.40, 95% CI, 0.16 to 0.98) compared with the low-fit group. In addition, ORs for the prevalence of low HDL-C in the mid-fit and high-fit groups were significantly lower (OR = 0.35, 95% CI, 0.14 to 0.86; and OR = 0.19; 95% CI, 0

  19. Ethical Issues for Clinical Studies That use Human Embryonic Stem Cells: The 2014 Revisions to the Japanese Guidelines.

    The use of human embryonic stem cells (hESCs) in clinical studies has been expanding in recent years. The application of hESCs in clinical studies raises ethical issues from a different standpoint compared with the use of other types of stem cells. In Japan, the Guidelines on the Derivation of Human Embryonic Stem Cells, and Guidelines on the Distribution and Utilization of Human Embryonic Stem Cells had been revised for clinical studies in 2014. In the revised guidelines, the method for protection of personal information was changed to offer the choice between unlinkable anonymization and linkable anonymization, to enable the use of information on diseases suffered by donors and the assurance of traceability for safety. Procedures for re-consent are generally prohibited out of consideration for donors' feelings. However, obtaining re-consent is permitted when consent for re-consent has been received in advance and approval has been given by an ethical review board, in which case the donors may be contacted. Incidental findings obtained from hESCs are not disclosed individually to donors, while the research results should be actively published for the common good. These guidelines have enabled the derivation, distribution, and use of hESCs for clinical studies.

    Background Integrated care focuses on care coordination and patient centeredness. Integrated care supports continuity of care over time, with care that is coordinated within and between settings and is responsive to patients’ needs. Currently, little is known about care integration for rural patients. Objective To examine challenges to care integration in rural safety net clinics and strategies to address these challenges. Research Design Qualitative case study. Participants Thirty-six providers and staff from 3 rural clinics in the Safety Net Medical Home Initiative. Methods Interviews were analyzed using the framework method with themes organized within 3 constructs: Team Coordination and Empanelment, External Coordination and Partnerships, and Patient-centered and Community-centered Care. Results Participants described challenges common to safety net clinics, including limited access to specialists for Medicaid and uninsured patients, difficulty communicating with external providers, and payment models with limited support for care integration activities. Rurality compounded these challenges. Respondents reported benefits of empanelment and team-based care, and leveraged local resources to support care for patients. Rural clinics diversified roles within teams, shared responsibility for patient care, and colocated providers, as strategies to support care integration. Conclusions Care integration was supported by 2 fundamental changes to organize and deliver care to patients—(1) empanelment with a designated group of patients being cared for by a provider; and (2) a multidisciplinary team able to address rural issues. New funding and organizational initiatives of the Affordable Care Act may help to further improve care integration, although additional solutions may be necessary to address particular needs of rural communities.

    Background and Purpose Valproate is used as a prophylactic drug for migraine, but it is not be effective in all patients. We used medical records to investigate which clinical factors affected the response to valproate in patients with migraine as an original headache, and established a scoring system for predicting the clinical response to prophylactic therapy. Methods We investigated clinical factors from the medical records of 95 consistent responders (CRs) and 24 inconsistent responders (IRs) to valproate. Results Multivariate stepwise logistic regression analysis revealed that a history of hyperlipidemia and hay fever and the complication of depression or other psychiatric disorder were significant factors that independently contributed to a negative response, with odds ratios of 6.024 [no vs. yes; 95% confidence interval (CI)=1.616–22.222], 2.825 (no vs. yes; 95% CI=1.046–7.634), and 2.825 (no vs. yes; 95% CI=1.052–7.576), respectively. A predictive index (PI) of the clinical response to valproate in patients with migraine was calculated using the regression coefficients of these three factors as an integer, and the index was significantly higher for IRs than for CRs (1.46±1.10 vs. 0.69±0.74, mean±SD, p<0.001). Conclusions The obtained PI may represent an appropriate scoring system for predicting the responses in these patients.

    Brain monoaminergic neurotransmission is involved in the pathophysiology of various psychiatric disorders including depression. Reliable indicators of central monoaminergic activity might be helpful to specifically identify and differentiate dysfunctions in individual patients in order to selectively adjust medication and predict clinical response. In patients with depression, predictors of treatment response to serotonergic versus non-serotonergic (e.g., noradrenergic) antidepressants could be of considerable clinical relevance by avoiding unfavorable factors such as a prolonged duration of the disorder, risk of suicidality and therapy-resistance. Consequently, these tools might help to decrease direct and indirect costs of treatment. The loudness dependence of the N1/P2 component of auditory evoked potentials (LD) has been proposed as a noninvasive neurophysiological indicator of central serotonergic function. This review focuses on recent studies providing evidence for the validity of LD as an indirect serotonergic marker and highlights data on the clinical application in terms of prediction of treatment response in patients with depression.

    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

    Background: Alopecia can be a manifestation of mycosis fungoides (MF); however, the prevalence is unknown. Aims: We sought to describe the clinicopathologic presentation of alopecia in patients with diagnosis of MF. Methods: A retrospective analysis of patients with biopsy-proven MF, who were evaluated at our cancer center from 2002 to 2012, was performed to identify patients with alopecia. Results: Five patients with alopecia were identified from reviewing of 157 patients with MF. The male:female ratio was 3:2, and the mean age of patients was 42.8 years. Two of these patients showed patchy hair loss on scalp which was clinically identical to alopecia areata. In remaining three patients, hair loss was seen in areas of MF lesions, and epidermal changes consisted of patch- and plaque-type lesions of MF, tumors, and follicular lesions (follicular MF) were also present. In two of these patients, lymphadenopathy without any visceral involvement was detected. Conclusions: Alopecia was observed in 5 (3.18%) patients with MF, which makes it a rare finding, which included alopecia areata-like patchy loss in 2 and alopecia within MF lesions in 3.

    The aim of this study was to describe the presenting clinical manifestations and syndromes of Filipino patients on diagnosis of systemic lupus erythematosus (SLE). We performed a retrospective review of medical records of Filipino SLE patients included in the lupus database of the University of Santo Tomas (UST) in Manila, Philippines. All patients fulfilled the American College of Rheumatology criteria for SLE. The following data were recorded: (1) demographic profile, (2) clinical manifestations on SLE diagnosis, and (3) clinical syndromes prior to and during fulfillment of diagnostic criteria for SLE and disease interval from diagnosis of a clinical syndrome to SLE diagnosis. Clinical data of 1,070 patients entered into the UST lupus database as of October 2005 were analyzed. The average age at SLE diagnosis was 28.5 +/- 11.5 (range 5-71) years, with 1,025 female and 45 male subjects. The most common presenting manifestation was arthritis (68%), followed by malar rash (49%), renal involvement (47%), photosensitivity (33%), and oral ulcers (33%). The following clinical syndromes were recorded prior to or during SLE diagnosis: nephrotic syndrome (30%), undifferentiated connective tissue disease (UCTD) (22%), autoimmune hemolytic anemia (AIHA) (6%), and idiopathic thrombocytopenic purpura (ITP) (6%). Among these, AIHA preceded the diagnosis of SLE at the longest interval (20.3 +/- 30.6, range 1-194 months). In this large database of Filipino patients with SLE, the most common presenting manifestation was arthritis, with renal involvement occurring in almost 50%. Among the clinical syndromes, nephrotic syndrome was the most common, whereas AIHA recorded the longest interval preceding SLE diagnosis, at an average of 20.3 months. Our findings are similar to data from other countries and emphasize the broad range of manifestations of SLE. The findings also reinforce the need to establish and maintain SLE databases to enhance awareness, early diagnosis, and more

    Membranous nephropathy (MN) is a leading cause of nephrotic syndrome in adults. Autoantibodies against M-type phospholipase A2 receptor (PLA2R) and thrombospondin type-1 domain-containing 7A (THSD7A), which mainly belong to the IgG4 subclass, were reported as associated antibodies for the development of MN. Although PLA2R is a major target antigen for idiopathic MN, the prevalence of MN patients seropositive for PLA2R in Japan is lower than that in other countries. In this study, we conducted immunohistochemical analysis of the presence of THSD7A and PLA2R in renal specimens of MN patients to estimate the prevalence of THSD7A/PLA2R-related idiopathic MN in Japan. Enhanced granular expression of THSD7A and PLA2R was detected in 9.1% and 52.7%, respectively, of the patients with idiopathic MN. Although none of patients with secondary MN displayed enhanced granular expression of THSD7A, 5.4% of them had enhanced granular expression of PLA2R. In conclusion, the prevalence of enhanced granular expression of THSD7A in the glomeruli of Japanese patients with idiopathic MN was higher than the prevalence of MN patients seropositive for THSD7A in USA and Europe.

    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.

We undertook a retrospective study of sporotrichosis in children and adolescents seen over a 10-year period, focusing on their clinical, epidemiologic, and mycologic features as well as treatment. We included 25 children with a mean age of 9.3 years. Most of those affected were schoolchildren (84%) from rural areas. The main clinical variety of sporotrichosis seen was the lymphocutaneous form (64%), followed by the fixed cutaneous form (36%), and one instance of the disseminated cutaneous form. Most lesions were located on the upper limbs (40%) and the face (36%). Sporothrix schenckii was isolated in all patients and 24 of 25 had a positive sporotrichin skin test. Nineteen patients were treated and cured clinically and mycologically with potassium iodide, three were cured with itraconazole and one with heat therapy.

    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

    Electronic medical record keeping has led to increased interest in analyzing historical patient data to improve care delivery. Such research use of patient data, however, raises concerns about confidentiality and institutional liability. Institutional review boards must balance patient data security with a researcher’s ability to explore potentially important clinical relationships. We considered the issues involved when patient records from health care institutions are used in medical research. We also explored current regulations on patient confidentiality, the need for identifying information in research, and the effectiveness of deidentification and data security. We will present an algorithm for researchers to use to think about the data security needs of their research, and we will introduce a vocabulary for documenting these techniques in proposals and publications.

    Patients, health-care professionals and the public expect safe health care. The system, however, is not safe and patients are being harmed. Workplace and organizational conditions and human factors contribute to these harms and a system approach is needed to avoid them. In clinical microsystems (CMS), the frontline units of health care, staff and patients can make care safer by learning about their system, its processes, members and purposes. Approaches from patient safety should be integrated in the daily work of every member of the CMS to reduce risk, implement safe practices and learn from errors. We summarize methods for use in CMS and offer ideas for fostering a proactive culture of patient safety. PMID:23137384

    Age-related macular degeneration (AMD) in the Japanese often shows different clinical features from those described in Caucasians. For example, we often observe choroidal neovascularization (CNV) in elderly patients without drusen in the fundus. The high incidence of polypoidal choroidal vasculopathy (PCV) in AMD among Japanese is well-known. The reason why such differences occur in clinical manifestations of AMD has been one of my main interests. In this review article, I will discuss the characteristics of AMD in the Japanese population, as found in our recent study. I. Prevalence and clinical characteristics of AMD in the Japanese population. Cohort studies are important to determine the prevalence and incidence of diseases. In Japan, cohort studies began to be carried out rather late compared with Western countries. Although good cohort studies from Japan are reported in the literature, the size of the cohorts was not sufficiently large to determine the prevalence of AMD. However, a recent meta-analysis of Asian cohorts has shown that the prevalence of late AMD in Asians is not different from that reported in Caucasians. On the other hand, the prevalence of early AMD appears lower in the Japanese than in Caucasians. Recently, we have published the results of the Nagahama Cohort study. In this cohort study, we found a high prevalence of drusen. It seems that the incidence of dry AMD is likely to increase among Japanese. In Japan, most retina specialists classify AMD into three categories : typical AMD, PCV, and retinal angiomatous proliferation (RAP). However, there are no definite diagnostic criteria to distinguish between the three conditions. To compare the clinical features of Japanese and Western cases of AMD, and to determine the incidence of the three types of AMD, we exchanged data about 100 consecutive cases between Kyoto University and Centre d'Ophtalmologie de Paris, France.

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

    Although postpartum depression and other perinatal disorders have been the subject of increased research attention, important questions remain regarding women who actively seek psychiatric treatment during pregnancy and the postpartum period. In this study, we examined clinical records of 500 perinatal psychiatric patients who received treatment in a psychiatric day hospital (N = 398) or outpatient behavioral health clinic (N = 102). Patients' presenting diagnoses, psychiatric history, treatment course, and depressive symptoms were recorded. The majority of women had major depression as their primary diagnosis, with an average Edinburgh Postnatal Depression Scale score of over 20. Many depressed patients were diagnosed with comorbid anxiety and substance abuse disorders. Although most women were willing to take psychotropic medications, a sizable minority were not, particularly those who were breast-feeding. For more than a third of the sample, the treatment sought while pregnant or postpartum represented their first contact with the mental health system. Treatment implications are discussed.

    The Latino population in rural Minnesota has grown significantly in recent years. Despite the increase, few studies have considered whether these newcomers are satisfied with the care they receive from local medical clinics. This article describes the results of a pilot study that assessed 20 Mexican patients' satisfaction with care they received in a primary care clinic in rural central Minnesota. Participants were interviewed using questions from Stewart's Interpersonal Care Survey and open-ended questions. Results showed the patients were generally satisfied with their health care. However, they suggested improvements in the areas of communication and involvement in decisions. Answers to the open-ended questions suggested that even though patients seemed satisfied with their care, they still strongly desired a bilingual physician.
