    Diabetic patients have a high risk for cardiovascular events. The role of myocardial perfusion imaging was investigated in asymptomatic diabetic patients to evaluate short-term prognosis in a Japanese population. A total of 506 asymptomatic patients ≥50 years of age who had carotid artery maximum intima-media thickness ≥1.1 mm, urinary albumin excretion of ≥30 mg/g creatinine, with additional criteria of abdominal obesity, low HDL cholesterol, high triglyceride level, and hypertension were enrolled and followed up over a 3-year period. Gated SPECT with stress-rest protocol was performed and analyzed by summed defect scores and QGS software. One-year cardiovascular events were analyzed. Myocardial ischemia was observed in 17% of patients, and abnormal perfusion findings of ischemia and/or scar were observed in 32% of patients. By the end of the 1-year follow-up, 33 (6.5%) cardiovascular events occurred including 6 all-cause deaths. Patients with summed stress score (SSS) >8 had a higher incidence of either death or cardiovascular events. Event-free survival rates for SSS 0-3, 4-8, 9-13, and ≥14 were 0.96, 0.95, 0.82, and 0.76, respectively. Multivariate Cox regression analysis showed that significant variables were SSS, history of cerebrovascular accident, and electrocardiographic abnormality at rest. The 1-year interim summary showed that cardiovascular events were significantly higher in patients with SPECT abnormality, although hard cardiac event rate was relatively low. Targeted treatment strategy is required for asymptomatic but potentially high-risk diabetic patients. (orig.)

    This study was designed to determine the clinical risk for hard events after normal single-photon emission computed tomography (SPECT) and to identify the predictors of increased risk in asymptomatic patients with diabetes mellitus, based on a Japanese Assessment of Cardiac Events and Survival Studies by quantitative gated SPECT (J-ACCESS)-2 study. A total of 513 consecutive asymptomatic patients who underwent stress 99m Tc-tetrofosmin SPECT in Japan were included in this study. Based on SPECT image and QGS data, 319 had a summed stress score ≤3, a summed difference score <2 and normal cardiac function (end-systolic volume ≤60 ml, males, ≤40 ml females; left ventricular ejection fraction ≥49%, males, ≥50% females). Myocardial perfusion was normal in 62% of this study population. During a 3-year follow-up, there were a total of 8 cardiac major events (2.5%): 2 cases of sudden death, 5 of acute coronary syndrome, and 1 of hospitalization because of congestive heart failure. The annual major event rate was 0.8%. Subjects undergoing coronary angiography had significantly more major events than those who did not among normal SPECT subjects (P=0.01). Kaplan-Meier analysis showed that the cardiac major events rate was very low, and subjects with normal SPECT can be considered as low risk among asymptomatic patients with diabetes. An excellent prognosis was associated with a normal SPECT in asymptomatic patients with diabetes, so these patients can be exempted from further invasive procedure. (author)

    Full Text Available A wide variety of disorders of diverse pathogenic mechanisms can trigger spinal cord dysfunction in HIV-1-infected patients. The most common such condition is HIV-1-associated myelopathy (HAM which characteristically seen during advanced HIV infection in patients with low CD4 cell counts and previous AIDS-defining diagnoses. Histologically seen in approximately 30% of AIDS patients, but only 10% have clinical symptoms related to the disease. We describe an unusual case of HAM in previously asymptomatic patient with relatively low CD4 cell count (78 cells/mm3. The patient unaware of her seropositive status presented with a clinically slowly progressive myelopathy with difficulty in walking without assistance. We discharged a patient on antiretroviral therapy. We also review the disorders reported to derange spinal cord function in previously asymptomatic HIV-1 infected patients with preserved counts.

    Human immunodeficiency virus (HIV-1) infection and acquired immunodeficiency syndrome (AIDS) lead to neurocognitive disorders; however, there is still much knowledge to be gained regarding HIV-associated neurocognitive disorders. The purpose of this study was to assess the cognitive performance, instrumental activities of daily living, depression, and anxiety in patients with asymptomatic HIV-1 infections compared with seronegative participants without neurocognitive impairment. We studied a sample consisted of 60 patients with asymptomatic HIV-1 infections and 60 seronegative participants without neurocognitive impairment from the city of Barranquilla, Colombia, with a mean age of 36.07 years. A protocol of neuropsychological and psychopathological tests was applied to the participants. The group of patients with asymptomatic HIV infections significantly underperformed on tasks that assessed global cognitive screening, attention span, learning, phonemic verbal fluency, auditory-verbal comprehension, information processing speed, cognitive flexibility, and motor skills compared to the group of seronegative participants. No significant differences were found in memory, visual confrontation naming, vocabulary, inhibition, and instrumental activities of daily living. Additionally, the patients with asymptomatic HIV-1 infection had a higher anxiety index than the seronegative participants, but no significant difference was found in depression. A correlation was found between depression and anxiety. In conclusion, the patients with asymptomatic HIV-1 infection had lower cognitive performances than the seronegative participants in the cognitive functions mentioned above and more anxiety but still performed the instrumental activities of daily living.

    Risk stratification of screened populations could help improve colorectal cancer (CRC) screening. Use of the modified Asia-Pacific Colorectal Screening (APCS) score has been proposed in the Asia-Pacific region. This study was performed to build a new useful scoring model for CRC screening. Data were reviewed from 5218 asymptomatic Japanese individuals who underwent their first screening colonoscopy. Multivariate logistic regression was used to investigate risk factors for advanced colorectal neoplasia (ACN), and a new scoring model for the prediction of ACN was developed based on the results. The discriminatory capability of the new model and the modified APCS score were assessed and compared. Internal validation was also performed. ACN was detected in 225 participants. An 8-point scoring model for the prediction of ACN was developed using five independent risk factors for ACN (male sex, higher age, presence of two or more first-degree relatives with CRC, body mass index of > 22.5 kg/m 2 , and smoking history of > 18.5 pack-years). The prevalence of ACN was 1.6% (34/2172), 5.3% (127/2419), and 10.2% (64/627) in participants with scores of statistic of the scoring model was 0.70 (95% confidence interval, 0.67-0.73) in both the development and internal validation sets, and this value was higher than that of the modified APCS score [0.68 (95% confidence interval, 0.65-0.71), P = 0.03]. We built a new simple scoring model for prediction of ACN in a Japanese population that could stratify the screened population into low-, moderate-, and high-risk groups.

    Full Text Available Background: Psychiatric morbidity in human immunodeficiency virus (HIV patients is being studied all over the world. There is paucity of Indian literature particularly in asymptomatic HIV individuals. Aim: The aim of the following study is to establish the prevalence and the determinants of psychiatric morbidity in asymptomatic HIV patients. Materials and Methods: A cross-sectional study was undertaken to assess psychiatric morbidity as per ICD-10 dacryocystorhinostomy criteria in 100 consecutive asymptomatic seropositive HIV patients and an equal number of age, sex, education, economic and marital status matched HIV seronegative control. All subjects were assessed with the general health questionnaire (GHQ, mini mental status examination, hospital anxiety and depression scale (HADS and sensation seeking scale (SSS and the scores were analyzed statistically. Results: Asymptomatic HIV positive patients had significantly higher GHQ caseness and depression but not anxiety on HADS as compared to HIV seronegative controls. On SSS asymptomatic HIV seropositive subjects showed significant higher scores in thrill and adventure seeking, experience seeking and boredom susceptibility as compared to controls. HIV seropositive patients had significantly higher incidence of total psychiatric morbidity. Among the individual disorders, alcohol dependence syndrome, sexual dysfunction and adjustment disorder were significantly increased compared with HIV seronegative controls. Conclusion: Psychiatric morbidity is higher in asymptomatic HIV patients when compared to HIV seronegative controls. Among the individual disorders, alcohol dependence syndrome, sexual dysfunction and adjustment disorder were significantly increased compared with HIV seronegative controls. High sensation seeking and substance abuse found in HIV seropositive patients may play a vital role in engaging in high-risk behavior resulting in this dreaded illness.

    Simões-Silva, Liliana; Correia, Inês; Barbosa, Joana; Santos-Araujo, Carla; Sousa, Maria João; Pestana, Manuel; Soares-Silva, Isabel; Sampaio-Maia, Benedita

    Currently, chronic kidney disease (CKD) is a global health problem. Considering the impaired immunity of CKD patients, the relevance of infection in peritoneal dialysis (PD), and the increased prevalence of parasites in CKD patients, protozoa colonization was evaluated in PD effluent from CKD patients undergoing PD. Overnight PD effluent was obtained from 49 asymptomatic stable PD patients. Protozoa analysis was performed microscopically by searching cysts and trophozoites in direct wet mount of PD effluent and after staining smears. Protozoa were found in PD effluent of 10.2% of evaluated PD patients, namely Blastocystis hominis, in 2 patients, and Entamoeba sp., Giardia sp., and Endolimax nana in the other 3 patients, respectively. None of these patients presented clinical signs or symptoms of peritonitis at the time of protozoa screening. Our results demonstrate that PD effluent may be susceptible to asymptomatic protozoa colonization. The clinical impact of this finding should be further investigated.

    The data about cardiovascular (CV) changes in patients with asymptomatic primary hyperparathyroidism (PHPT) are scarce. The aim of this study is to compare cardiac structure and functions in patients with asymptomatic PHPT and controls by using tissue Doppler echocardiography. Thirty-eight patients with asymptomatic PHPT and 31 sex- and age-matched controls with similar cardiac risk factors were evaluated. There was no significant difference in ejection fraction (EF) between the patients and the controls [64±5.95 vs 62±3.25% (p=0.094)]. Left ventricular mass index (LVMI) was significantly higher in patients than controls [105.96 (66.45-167.24) vs 93.79 (64.25- 139.25) g/m2, p=0.014]. There was a significant correlation between LVMI and serum calcium (Ca) (r=0.240, p<0.005). Myocardial performance index (MPI) was significantly higher in patients than controls [0.49 (0.35-0.60) vs 0.39 (0.33-0.62), p<0.001]. There was positive correlation between theMPI and serumCa levels (r=0.505, p<0.001), parathyroid hormone (PTH) levels (r=0.464, p<0.001) and LVMI (r=0.270, p<0.005). When the normotensive patients and controls were evaluated, the difference between the groups remained statistically significant considering LVMI and MPI [109 (66.45-167.24) g/m2 vs 94.17 (64.25-75.10) g/m2, p=0.03; and 0.49 (0.35-0.60) vs 0.39 (0.33-0.62), p<0.01, respectively]. There were significant correlations between MPI and Ca (r=0.566, p<0.001), and PTH (r=0.472, p<0.001). Our study results showed that cardiacmorphology and diastolic functions are altered in the patients with asymptomatic PHPT. High serum PTH and Ca levels may have an impact on these CV changes. Whether these subtle CV changes would affect cardiac systolic functions and mortality in patients with asymptomatic PHPT should be investigated in further prospective studies.

    The sacroiliac (SI) joints of 45 asymptomatic subjects were prospectively studied to define better the normal appearance of SI joints on CT scans and therby attach appropriate significance to CT signs of sacroiliitis. Joint space narrowing, subchondral sclerosis, erosions, ankylosis, osteophytes, subchondral cysts, and symmetry were evaluted. The results indicate that the SI joints demonstrate symmetry in patients under the age of 30 (100% of subjects in this age group). Those CT findings of sacroiliitis that occurred infrequently in the asymptomatic population, and hence may represent good indicators of sacroiliac disease, include increased sacral subchondral sclerosis in subjects under the age of 40 (11%), bilateral or unilateral uniform joint space of less than 2 mm (2% or 0%, respectively), erosions (2%), and intraarticular ankylosis (0%)

    Full Text Available Microcytosis is observed in healthy Japanese breed dogs. The aim of the study was to evaluate the frequency and intensity of asymptomatic anisocytosis using a three-grade scale in Japanese dog breeds with special emphasis on the following indices: mean cell volume, mean cell haemoglobin, mean cell haemoglobin concentration, and red blood cell distribution width. The retrospective study included analyses of blood morphology and blood smear for clinically healthy Japanese dog breeds Shiba, Akita, and Hokkaido aged from 6 months to 14 years, performed as a part of preventative care. A total of 74 dogs of both sexes were qualified for the study. The group included both neutered and non-neutered animals (Akita – 17 females, 12 males, Shiba – 24 females, 18 males, Hokkaido – 2 females, 1 male. The blood smear revealed significant anisocytosis in 60.8% and mild anisocytosis in 28.4% of the tested dogs – 89.2% in total. Microcytosis was reported for 25.7% of the tested Japanese breed dogs. Reduced mean cell haemoglobin and mean cell haemoglobin concentration were diagnosed in 75.7% and 40.5% of dogs, respectively. Red blood cell distribution width as an anisocytosis indicator exceeded the norm in 12% of the tested dogs. Compared to mixed breed dogs, the Japanese breeds had a reduced mean cell volume, mean cell haemoglobin concentration and significant anisocytosis in the blood smear as well as a higher red blood cell distribution width indicator. Veterinarians should consider these differences when interpreting the results of morphological blood tests.

    Among the pregnancy urinary tract infections, asymptomatic bacteriuria (ASB) is the most common one. Untreated ASB can progress to pyelonephritis in 30-50% of the patients and can also result in prematurity in 27% of the pregnancy so it needs immediate diagnosis and treatment. In this study, we wanted to evaluate procalcitonin levels, compared to other inflammatory in pregnant women with ASB. The study was designed between the period of January 2012 and February 2013 at Sakarya University School of Medicine, Department of Gynecology and Obstetrics. The study population included 30 pregnant patients with asymptomatic bacteriuria and 39 healthy pregnant controls. Mean age was 28 (SD, 5.5) of the study population; mean maternal weight was 70 (SD, 8) kilogram. There were no statically significant differences between the groups according to the routine biochemical parameters, but gestational age was significantly lower in the ASB group compared to the controls (20.4 vs 28.6, respectively; p 0.05 ng/ml and 21(70%) patients had negative procalcitonin levels (Chi-squrae, p treatment of the first ASB diagnosis. Procalcitonin levels were significantly higher in ASB group than the control group and serum procalcitonin levels were higher in pregnant women with recurrent ASB. This finding is an important result revealed that high procalcitonin level can predict the further urinary tract infection risk. Finally, serum procalcitonin levels were normal in healthy pregnant women while other inflammatory markers such as WBC, ESR and CRP levels were higher.

    Purpose: It is important that early diagnosis and treatment of coronary artery disease in diabetic patients, but there are few reports on the prevalence of stress-induced myocardial perfusion abnormalities and the rates of cardiac event in patients with type 2 diabetes. We evaluated the scan findings on gated myocardial perfusion SPECT in asymptomatic diabetic patients. Methods: We performed pharmacological stress test and gated perfusion SPECT in 69 diabetic patients without cardiovascular symptom (mean age: 65 year, male 31 and female 38). Patients underwent two-day imaging protocol and stress study was performed injection of Tc-99m MIBI during adenosine infusion. We followed up these patients by reviewing medical records. Results: Fifty-two of 69 patients (74.5%) showed normal scan findings and 17 patients (24.6%) showed reversible or fixed perfusion defects. Three of 52 patients with normal scan findings showed decreased LV ejection fraction and decreased wall motion. Twenty-three patients with normal scan findings were possible to follow up for more than 1yr (mean time: 18.3±3.3 mo.) and they all had no cardiac event. Three patients with reversible perfusion defects were performed coronary angioplasty. Conclusion: Myocardial perfusion SPECT is a noninvasive method and maybe useful in early diagnosis and predicting prognosis in diabetic patients

  16. [The management of asymptomatic bacteriuria in different patient population].

    Ivanov, M-L; Malinverni, R

    2008-11-12

    Who should be screened for asymptomatic bacteriuria (AB) and who should be treated? This review updates some aspects of the management of AB in different patient populations. A systematic screening for AB is recommended for pregnant women because of a significant risk of complications. In these cases as well as before any uro-gynecologic surgical procedure treatment of AB is strongly recommended. The management of AB in immunosuppressed or transplanted patients is more controversial. In other populations treating AB is not recommended and the outcome seems to be worse in case of treatment due to possible side effects and selection of resistant organisms. Recent studies have shown a considerable gap between clinical practice and recommendations.

    The optimal approach is controversial in asymptomatic patients who are coincidentally found to have evidence of an accessory pathway (AP) on an ECG. The risk of sudden cardiac death (SCD) is low, and the risk of developing symptoms also appears to be low, although a wide range of incidences have been reported. In our trial, we tested the hypothesis that if prophylactic accessory-pathway ablation performed at the time of the initial electrophysiological testing would improve the long-term outcome in asymptomatic patients with a Wolff-Parkinson-White electrocardiographic pattern. Recruitment of patients began on February 1, 2004, and ended on February 5, 2009. All 110 asymptomatic patients were hospitalized and underwent electrophysiological testing the same day to assess the inducibility of atrioventricular reciprocating tachycardia. The anterograde effective refractory period of the accessory pathway was defined as the longest coupling interval at which anterograde block in the bypass tract was observed. For the statistical analysis, the statistical software SPSS version 15.0 for Windows (SPSS Inc., Chicago, IL, USA). Of 110 asymptomatic patients with a Wolff-Parkinson-White electrocardiographic pattern, 80 patients were ablated. Ablation group consisted of these patients. Control group consisted of remaining 30 and were divided into two groups according to the anterograde effective refractory period of the accessory pathway. There was no significant difference between three groups in terms of arrhythmic events (p: 0.58). Asymptomatic patients with the Wolff-Parkinson-White syndrome do not require prophylactic ablation, since they remain asymptomatic for many years.

    Patients with cerebral infarction have a high prevalence of asymptomatic coronary artery disease (CAD) and other vascular diseases, but there is a lack of such data for Japanese patients, so the present study investigated the prevalence of cardiovascular disease (CVD) in Japanese patients and determined the predictors of CAD. The study group comprised 104 patients with cerebral infarction who had no history of CVD. All patients underwent coronary computed tomographic angiography, and systematic evaluation was done on the basis of the presence of other vascular diseases, CVD risk markers, and the degree of atherosclerosis. Of the total, 39 patients (37.5%) had CAD, 9 (8.7%) had carotid artery stenosis, 9 (8.7%) had peripheral artery disease of the lower limbs, and 3 (2.9%) had atherosclerotic renal artery stenosis. Multiple regression analysis showed that the presence of CAD was independently associated with metabolic syndrome (odds ratio (OR) 5.008, 95% confidence interval (CI) 1.538-16.309; p<0.01) and intracranial large artery atherosclerosis (OR 4.979, 95% CI 1.633-15.183; p<0.01). Japanese patients with cerebral infarction have a high prevalence of CVD, especially asymptomatic CAD. Both metabolic syndrome and intracranial large artery atherosclerosis may be potential predictors for identifying patients with cerebral infarction who are at the highest risk of asymptomatic CAD.

  3. Asymptomatic bacteriuria.

    Nicolle, Lindsay E

    2014-02-01

    Asymptomatic bacteriuria is a common finding. Inappropriate antimicrobial treatment of asymptomatic bacteriuria has been identified as a major issue for antimicrobial stewardship programs. This review summarizes and evaluates recent studies which extend our knowledge of the occurrence, management, and outcomes of bacteriuria. The reported prevalence of bacteriuria is higher in some developing countries than generally reported for developed countries, but reasons for this remain unclear. Clinical studies of young women, renal transplant patients, and patients undergoing minor nontraumatic urologic procedures confirm that treatment of asymptomatic bacteriuria for these populations is not beneficial, and may be harmful. There is also no benefit for treatment of asymptomatic bacteriuria prior to orthopedic surgery to decrease postoperative surgical site infection. Studies continue to report substantial inappropriate antimicrobial use for treatment of asymptomatic bacteriuria. Recent publications confirm that asymptomatic bacteriuria is benign in most patients. Management strategies for pregnant women with recurrent bacteriuria require further clarification. There is a continuing problem with inappropriate treatment of asymptomatic bacteriuria, and sustainable strategies to optimize antimicrobial use for this problem are needed.

    Despite clinical practice guidelines, asymptomatic bacteriuria (ASB) in older people is frequently treated. A common reason for treating ASB is a change in mental status. To determine how often asymptomatic UTI is treated in older medically ill delirious individuals and its association with functional recovery. Consecutive older medical in-patients were screened for delirium, and followed in hospital. Treatment for asymptomatic UTI was defined as documented treatment for a possible urinary tract infection with antibiotics, without concurrent infectious or urinary symptoms. The primary outcome was functional recovery at discharge or 3 months post-discharge. Poor functional recovery was defined by any one of death, new permanent long-term institutionalization or decreased ability to perform activities of daily living. The study sample comprised 343 delirious in-patients, of which 237 (69%) had poor functional recovery. Ninety two (27%) delirious in-patients were treated for asymptomatic UTI. Treatment for asymptomatic UTI was associated with poor functional recovery compared to other delirious in-patients (RR 1.30, 95% CI: 1.14-1.48 overall). Similar results were seen when the analysis was restricted to only bacteriuric delirious individuals. Seven (7.5%) individuals treated for asymptomatic UTI developed Clostridium difficile infection compared to eight (3.2%) in the remainder of the delirious cohort (OR 2.45, 95% CI: 0.86-6.96). These results suggest that treatment of asymptomatic UTI in older medical in-patients with delirium is common, and of questionable benefit. Further research is needed to establish guidelines to minimize over-treatment of UTI in older delirious in-patients. Copyright © 2017 Elsevier B.V. All rights reserved.

    Factor VII deficiency is the most common among the rare autosomal recessive coagulation disorders worldwide. In factor VII deficient patients, the severity and clinical manifestations cannot be reliably determined by factor VII levels. Severe bleeding tends to occur in individuals with factor VII activity levels of 2% or less of normal. Patients with 2-10% factor VII vary between asymptomatic to severe life threatening haemorrhages behaviour. Recombinant factor VIIa (rFVIIa) is the most common replacement therapy for congenital factor VII deficiency. However, unlike haemophilia patients for whom treatment protocols are straight forward, in asymptomatic factor VII deficiency patients it is still debatable. In this study, we demonstrate that a single and very low dose of recombinant factor VIIa enabled asymptomatic patients with factor VII deficiency to go through major surgery safely. This suggestion was also supported by thrombin generation, as well as by thromboelastometry.

    1995-01-01

    Contrast-enhanced MR imaging of the spine after surgery for lumbar disk herniation almost always shows pathologic changes. To investigate to what extent these changes are correlated to patients' actual clinical symptoms, we compared the postoperative MR findings in 19 asymptomatic patients with 42 symptomatic patients (43 levels). The asymptomatic patients underwent MR examination one year after surgery. Twenty-six of the symptomatic patients underwent MR one year of less after surgery, and in 16 patients (17 levels) MR was performed more than one year after surgery. Sixteen percent of the asymptomatic and 42% of the symptomatic patients had disk herniation at the level of previous surgery. Most of the herniated disks were found in the symptomatic patients less than one year after surgery. The amount of epidural scar tissue, displacement and thickening of nerve roots, and compression of the dural sac were also studied. Disk herniation as a probable cause of recurrent sciatica was a common finding among symptomatic patients examined one year or less after surgery. In comparing asymptomatic patients and symptomatic patients with more than one year between surgery and MR examination, no significant radiologic differences, including disk herniation, were found.

    Meiland, R; Geerlings, S E; Hoes, A W; Hoepelman, I M

    2002-04-06

    Asymptomatic bacteriuria is a common medical condition, especially in women and elderly people. It is generally considered to be a benign condition, which does not require screening or antibiotic treatment. However, there are a few exceptions for which screening is possibly worthwhile. For children it is unclear whether the early detection of ASB can result in better clinical outcomes. Screening is therefore not advised, except for young children during the first few months after a symptomatic urinary tract infection. For pregnant women the use of screening for ASB is also unclear and in general not indicated. Research is necessary into the possible transition from ASB to pyelonephritis and the possible connection with low birth weight and premature births. There are indications that ASB in women with type I diabetes mellitus can lead to a deterioration in the renal function, yet these are insufficient to recommend screening as a routine procedure.

  11. Management of an asymptomatic patient with the apical variant of hypertrophic cardiomyopathy.

    Trojan, Meghan K Borden; Biederman, Robert W

    2017-07-01

    Healthcare professionals are faced with challenging decisions regarding patient evaluation and management on a daily basis. Once a diagnosis is made, additional challenges include how to proceed with the management. Here, we present an eighty-two-year-old female who was incidentally diagnosed with the apical variant of hypertrophic cardiomyopathy on a transthoracic echocardiogram. She was found to have newly diagnosed atrial fibrillation, but was otherwise asymptomatic from a cardiomyopathy standpoint. No specific guidelines exist for this patient population. Therefore, how does one proceed with the management of an asymptomatic patient with the apical variant of hypertrophic cardiomyopathy? © 2017, Wiley Periodicals, Inc.

  12. Assessing Optimal Blood Pressure in Patients With Asymptomatic Aortic Valve Stenosis

    Nielsen, Olav W; Sajadieh, Ahmad; Sabbah, Muhammad

    2016-01-01

    BACKGROUND: Evidence for treating hypertension in patients with asymptomatic aortic valve stenosis is scarce. We used data from the SEAS trial (Simvastatin Ezetimibe in Aortic Stenosis) to assess what blood pressure (BP) would be optimal. METHODS: A total of 1767 patients with asymptomatic aortic...... stenosis and no manifest atherosclerotic disease were analyzed. Outcomes were all-cause mortality, cardiovascular death, heart failure, stroke, myocardial infarction, and aortic valve replacement. BP was analyzed in Cox models as the cumulative average of serially measured BP and a time-varying covariate.......039). CONCLUSIONS: Optimal BP seems to be systolic BP of 130 to 139 mm Hg and diastolic BP of 70 to 90 mm Hg in these patients with asymptomatic aortic stenosis and no manifest atherosclerotic disease or diabetes mellitus.

  14. Clinical Utility of Serologic Testing for Celiac Disease in Asymptomatic Patients

    2011-01-01

    Executive Summary Objective The objective of this evidence-based analysis was to evaluate the clinical utility of serologic testing for celiac disease in asymptomatic individuals presenting with one of the non-gastrointestinal conditions evaluated in this report. The clinical utility was based on the effects of a gluten-free diet (GFD) on outcomes specific to each of these conditions. The prevalence of celiac disease in asymptomatic individuals and one of these non-gastrointestinal conditions was also evaluated. Clinical Need and Target Population Celiac Disease Celiac disease is an autoimmune disease characterized by a chronic inflammatory state of the proximal small bowel mucosa accompanied by structural and functional changes. Technology Under Evaluation Serologic Tests for Celiac Disease There are a number of serologic tests for celiac disease available. Serologic tests are automated with the exception of the anti-endomysial antibody test, which is more time-consuming and operator-dependent than the other tests. Research Questions What is the prevalence of asymptomatic celiac disease in patients presenting with one of the non-gastrointestinal conditions evaluated? What is the effect of the gluten-free diet on condition-specific outcomes in patients with asymptomatic celiac disease presenting with one of the non-gastrointestinal conditions evaluated? What is the clinical utility of serologic testing for celiac disease in asymptomatic patients presenting with one of the non-gastrointestinal conditions evaluated? The clinical utility was defined as the impact of the GFD on disease specific outcomes. What is the risk of all-cause mortality and lymphoma in individuals with asymptomatic celiac disease? What is the budget impact of serologic testing for celiac disease in asymptomatic subjects presenting with one of the non-gastrointestinal conditions evaluated? Research Methods Study Population The study population consisted of individuals with newly diagnosed celiac

  15. Carboplatin dosing for adult Japanese patients.

    Ando, Yuichi; Shimokata, Tomoya; Yasuda, Yoshinari; Hasegawa, Yoshinori

    2014-02-01

    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.

  16. Association between aortic valve calcification and myocardial ischemia, especially in asymptomatic patients.

    Aortic valve calcification (AVC) is recognized as a manifestation of systemic arteriosclerosis. However, it is unclear whether AVC is associated with myocardial ischemia. Stress myocardial perfusion SPECT (MPS) is widely used for the diagnosis of myocardial ischemia. However, routine MPS is not recommended, particularly in asymptomatic patients. Accordingly, we investigated the hypothesis that the presence of AVC is strongly associated with inducible myocardial ischemia, even among asymptomatic patients. We investigated 669 consecutive patients who underwent both adenosine stress (201)Tl MPS and echocardiography. We evaluated the extent and severity of myocardial ischemia by the summed difference score (SDS). We defined the presence of myocardial ischemia as SDS ≥ 3 and moderate to severe ischemia as SDS ≥ 8. We classified the severity of AVC according to the number of affected aortic leaflets. We also compared the mean SDS and the prevalence of SDS ≥ 3 and SDS ≥ 8 among patients stratified by the severity of AVC. The presence of AVC was significantly associated with myocardial ischemia (odds ratio [OR], 1.56; 95% confidence interval [CI], 1.10-2.23; P = 0.013) and moderate to severe ischemia (OR, 2.16; 95% CI, 1.26-3.80; P = 0.0061). In 311 asymptomatic patients, AVC was strongly associated with moderate to severe ischemia (OR, 4.31; 95% CI, 1.67-12.8; P = 0.0043). However, the SDS value and the prevalence of SDS ≥ 3 and SDS ≥ 8 did not increase with increasing number of affected aortic leaflets. The presence of AVC may be associated with the presence of myocardial ischemia, particularly in asymptomatic patients. However, we found no association between the extent of AVC and inducible myocardial ischemia. The presence of AVC may be a useful anatomic marker to help identify patients at high risk of myocardial ischemia, particularly asymptomatic patients.

  17. Prognostic Value of Exercise-Stress Echocardiography in Asymptomatic Patients With Aortic Valve Stenosis.

    This study sought to evaluate the prognostic value of mean pressure gradient (MPG) increase and peak systolic pulmonary artery pressure (SPAP) measured during exercise stress echocardiography in asymptomatic patients with aortic stenosis (AS). Exercise testing is recommended in asymptomatic AS patients, but the additional value of exercise-stress echocardiography, especially the prognostic value of MPG increase and peak SPAP, is still debated. We enrolled all consecutive patients with pure, isolated, asymptomatic AS and preserved ejection fraction ≥50% and normal SPAP (20 mm Hg and/or SPAP at peak exercise >60 mm Hg). These 112 patients were managed conservatively. During a mean follow-up of 14 ± 8 months, an AS-related event occurred in 30 patients, and 25 patients underwent surgery. Neither MPG increase >20 mm Hg nor peak SPAP >60 mm Hg was predictive of occurrence of AS-related events or aortic valve replacement (all p > 0.20). In contrast, baseline AS severity was an important prognostic factor (all p < 0.01). In this observational study including 148 patients with asymptomatic AS, we confirmed and extended the importance of exercise testing for unveiling functional limitation. More importantly, neither the increase in MPG nor in SPAP at peak exercise was predictive of outcome. Our results do not support the use of these parameters in risk-stratification and clinical management of asymptomatic AS patients. Copyright © 2017 American College of Cardiology Foundation.

  18. Identification of bacteriology and risk factor analysis of asymptomatic bacterial colonization in pacemaker replacement patients.

    Xian-Ming Chu

    Full Text Available Recent researches revealed that asymptomatic bacterial colonization on PMs might be ubiquitous and increase the risk of clinical PM infection. Early diagnosis of patients with asymptomatic bacterial colonization could provide opportunity for targeted preventive measures.The present study explores the incidence of bacterial colonization of generator pockets in pacemaker replacement patients without signs of infection, and to analyze risk factors for asymptomatic bacterial colonization.From June 2011 to December 2013, 118 patients underwent pacemaker replacement or upgrade. Identification of bacteria was carried out by bacterial culture and 16S rRNA sequencing. Clinical risk characteristics were analyzed.The total bacterial positive rate was 37.3% (44 cases, and the coagulase-negative Staphylococcus aureus detection rate was the highest. Twenty two (18.6% patients had positive bacterial culture results, of which 50% had coagulase-negative staphylococcus. The bacterial DNA detection rate was 36.4 % (43 cases. Positive bacterial DNA results from pocket tissues and the surface of the devices were 22.0% and 29.7%, respectively. During follow-up (median, 27.0 months, three patients (6.8%, 3/44 became symptomatic with the same genus of microorganism, S. aureus (n=2 and S. epidermidis (n=1. Multivariable logistic regression analysis showed that history of bacterial infection, use of antibiotics, application of antiplatelet drugs, replacement frequency were independent risk factors for asymptomatic bacterial colonization.There was a high incidence of asymptomatic bacterial colonization in pacemaker patients with independent risk factors. Bacterial culture combined genetic testing could improve the detection rate.

    Full Text Available AIM: Chronic obstructive pulmonary disease (COPD is an independent risk factor for cardiovascular morbidity and mortality. The aim of this study was to determine the prevalence of asymptomatic peripheral arterial disease (PAD and the associated risk factors for patients with COPD. METHODS: This prospective cross-sectional study enrolled 427 COPD patients (mean age: 70.0 years without PAD symptoms consecutively. Demographic data, lung function and cardiovascular risk factors were recorded. The ankle-brachial index (ABI was used to detect PAD (ABI<0.90. RESULTS: The overall prevalence of asymptomatic PAD in the COPD patients was 8% (2.5% in the younger participants (<65 years of age, n = 118 and 10% in the elderly participants (≥65 years of age, n = 309. The COPD patients with asymptomatic PAD had a significantly higher rate of hyperlipidemia (47.1% vs. 10.4% and hypertension (79.4% vs. 45.8% than those without asymptomatic PAD (p<0.05. There was no significant difference in lung function (forced vital capacity and forced expiratory volume in one second between the two groups. In multivariate logistic regression, hyperlipidemia was the strongest independent factor for PAD (odds ratio (OR: 6.89, p<0.005, followed by old age (OR: 4.80, hypertension (OR: 3.39 and smoking burden (pack-years, OR: 1.02. CONCLUSIONS: The prevalence of asymptomatic PAD among COPD patients in Taiwan is lower than in Western countries. Hyperlipidemia, old age, hypertension, and smoking burden were the associated cardiovascular risk factors. However, there was no association between lung function and PAD in the COPD patients.

  20. Asymptomatic bacteriuria in adults.

    Colgan, Richard; Nicolle, Lindsay E; McGlone, Andrew; Hooton, Thomas M

    2006-09-15

    A common dilemma in clinical medicine is whether to treat asymptomatic patients who present with bacteria in their urine. There are few scenarios in which antibiotic treatment of asymptomatic bacteruria has been shown to improve patient outcomes. Because of increasing antimicrobial resistance, it is important not to treat patients with asymptomatic bacteriuria unless there is evidence of potential benefit. Women who are pregnant should be screened for asymptomatic bacteriuria in the first trimester and treated, if positive. Treating asymptomatic bacteriuria in patients with diabetes, older persons, patients with or without indwelling catheters, or patients with spinal cord injuries has not been found to improve outcomes.

  1. Noninvasive risk stratification for sudden death in asymptomatic patients with Wolff-Parkinson-White syndrome.

    Sudden cardiac death (SCD) as the first clinical manifestation of Wolff-Parkinson-White (WPW) syndrome is a well-documented, although rare occurrence. The incidence of SCD in patients with WPW ranges from 0% to 0.39% annually. Controversy exists regarding risk stratification for patients with preexcitation on surface electrocardiogram (ECG), particularly in those who are asymptomatic. This article focuses on the role of risk stratification using exercise and pharmacologic testing in patients with WPW pattern on ECG.

    Accelerated coronary artery disease and myocardial infarction in young patients with systemic lupus erythematosus is well documented; however, the prevalence of coronary involvement is unknown. Accordingly, 26 patients with systemic lupus were selected irrespective of previous cardiac history to undergo exercise thallium-201 cardiac scintigraphy. Segmental perfusion abnormalities were present in 10 of the 26 studies (38.5 percent). Five patients had reversible defects suggesting ischemia, four patients had persistent defects consistent with scar, and one patient had both reversible and persistent defects in two areas. There was no correlation between positive thallium results and duration of disease, amount of corticosteroid treatment, major organ system involvement or age. Only a history of pericarditis appeared to be associated with positive thallium-201 results (p less than 0.05). It is concluded that segmental myocardial perfusion abnormalities are common in patients with systemic lupus erythematosus. Whether this reflects large-vessel coronary disease or small-vessel abnormalities remains to be determined

    2012-01-01

    Diabetic patients with coronary artery disease are often asymptomatic, making appropriate care of such patients difficult. The purpose of this study was to investigate the prevalence of coronary lesions in asymptomatic diabetic patients. Coronary computed tomography (CT) angiography was performed in 120 consecutive diabetic patients (90 of whom were men, mean age 65, mean HbA1c 7.2%). Images from patients whose coronary artery calcium scores (CAC scores) were less than 400 were subjected to stenosis and plaque analysis. Significant stenosis was defined as coronary artery stenosis >70%. High-risk plaque was defined as plaque having both a CT density <30 Hounsfield Units (HU) and showing positive remodeling. Significant stenoses were identified in 30.5% of the patients. High-risk plaques were identified in 17.1% of the patients. Less than half of the high-risk plaques were obstructive plaques. There was a statistically significant association between significant stenosis and high-risk plaque by chi-square test (P=0.022). We found significant stenosis even in patients whose CAC score =0 at a rate of 5.0%. Using univariate logistic-regression analysis, we found that coronary risk factors associated with significant stenosis and high-risk plaque were dyslipidemia (P=0.033) and current smoking (P=0.030), respectively. We report for the first time, the prevalence of high-risk plaques in the arteries of patients with asymptomatic diabetes, as assessed by coronary CT angiography. (author)

  4. Attitude towards one's illness vs. attitude towards a surgical operation, displayed by patients diagnosed with asymptomatic abdominal aortic aneurysm and asymptomatic internal carotid artery stenosis.

    Stanisić, M; Rzepa, T

    2012-08-01

    Two most frequent asymptomatic diseases qualifying for vascular surgery are abdominal aortic aneurysm (AAA) and internal carotid artery stenosis (ICAS). Emotions experienced by the patient activate processes of dealing with the cognitive dissonance of asymptomatic disease. The aim of this paper was to compare the reasons involved in decision making on surgery in two asymptomatic vascular pathologies. Fifty patients were divided into two groups: the ICAS group-27 (CAS or CEA) and the AAA group-23 (EVAR or open surgical operation (OSR). Specific questionnaire regarding: 1) self-image; 2) attitude to one's illness; 3) reasons for decision on surgery was applied for the study. The χ² test was used to for the analysis. The AAA patients reacted emotionally (88.2%) comparing to ICAS patients reacting "rationally" (59.3%) (α=0.05). In AAA patients attitude towards themselves had worsened (α=0.001) AAA patients were less likely to seek support in decision on surgery (α=0.01). ICAS patients are internally motivated (78.7%), whereas AAA patients are externally motivated (63.9%) (α=0.001). Reasons underlying the decision on surgery, were predominantly rational (55.8%). In the process of decision-making on surgery by asymptomatic patients, evolutionary transformation takes place - the emotional attitude to one's illness leads to rationally evaluated decision. Regardless of the causes the process of making a decision on surgical operation tended to run more smoothly in ICAS patients. The ICAS patients tended to display a rational attitude to their illness. AAA patients displayed a distinctly emotional attitude towards their illness.

  6. Asymptomatic and Persistent Elevation of Pancreatic Enzymes in an Ulcerative Colitis Patient

    Elisa Liverani

    2013-01-01

    Full Text Available Azathioprine has been extensively used in the management of inflammatory bowel diseases. It might cause pancreatic damage in the form of either asymptomatic elevation in serum amylase/lipase or overt acute pancreatitis. Here we report the case of a 61-year-old patient with ulcerative colitis who had been treated with azathioprine for three years, achieving clinical remission. During treatment he presented an asymptomatic elevation of serum pancreatic enzymes, without any signs of pancreatitis at imaging. This evidence brought us to reassess the drug dosage, without achieving a normalization of biochemical analysis. Autoimmune pancreatitis was excluded. One year after the suspension of azathioprine, we still face persistent high levels of amylase/lipase. Normalization of enzymatic values in patients who develop intolerance to azathioprine, in the form of either asymptomatic elevation in serum amylase/lipase or overt acute pancreatitis, is usually achieved in about two months after stopping drug intake. Asymptomatic elevation in serum pancreatic enzymes in the absence of pancreatic disease is reported in the literature and defined as “Gullo’s syndrome,” but nobody of the subjects studied had been treated in the past with pancreatotoxic drugs. Might this case be defined as “benign pancreatic hyperenzymemia”?

    2006-01-01

    SPECT, coronary angiography and laboratories test were performed on 31 asymptomatic type 2 diabetes patients, in order to determine the relationship among the lipid levels in blood and the results of the SPECT. Patients were classified in two groups (positive SPECT or negative SPECT). Simple descriptive statistics were calculated for all variables in both groups. Positive SPECT was detected in 35,5% of the patients and negative SPECT in 64,5%.The coronary angiography and SPECT showed good correlation. Low values of HDLc showed significant association with the positive results of the SPECT. The logistical regression showed an increment of the capacity to predict a positive SPECT if the values of HDLc are used. Conclusion: The present investigation demonstrated a significant association among the low levels of HDLc in blood and the positive results of the SPECT. The low values of HDLc could predict the possibility of a positive SPECT in asymptomatic diabetic type 2 patients (au)

    Full Text Available INTRODUCTION: Majority of the time the patient of Diabetes presents with complications like Myocardial infarction, heart failure, being end stages of cardiovascular 2 disease associated with other macro and microvascular complications. If patients are screened at an early stage of Diabetes before the onset of symptoms the cardiovascular complications can be delayed and mortality can be reduced . There are only few studies in India done to screen asymptomatic diabetic individuals for cardiovascular compli cations. This study is done in view of screening the asymptomatic individuals in our area to prevent complications.

    1987-07-01

    Vaginal washings of 22 patients with vaginitis, 11 with vaginosis, and 12 healthy subjects were investigated quantitatively and qualitatively for aerobic and anaerobic bacteria and yeasts. Gardnerella vaginalis was recovered from 9 of the vaginitis patients, 7 of the vaginosis patients, and 4 of the asymptomatic subjects. Obligate anaerobes were found in 11 of the vaginitis patients, 4 of the vaginosis patients, and none of the control subjects. Bacteroides bivius was the anaerobe most frequently isolated from symptomatic subjects. Anaerobic vibrios were recovered twice from symptomatic subjects. The counts for Gardnerella vaginalis and anaerobes when present were generally very high. The most frequent aerobes were beta-hemolytic streptococci (group B) and staphylococci.

    Full Text Available A 66-year-old man with severe renal insufficiency presented with mild confusion associated with uremia. Cranial magnetic resonance imaging (MRI showed no remarkable changes. The patient was placed on short-duration hemodialysis (2 hours with smaller surface area and low blood flow (100 mL/min to avoid dialysis disequilibrium syndrome (DDS. His consciousness gradually improved and he did not develop apparent DDS symptoms. However, T2-weighted FLAIR MRI showed increased signal intensities bilaterally in the cortical and subcortical areas of the occipital lobe on day 15. In other words, cranial MRI showed cerebral edema, indicating asymptomatic DDS. On day 29, cranial MRI showed a return to findings on admission. In this case, because the patient did not have apparent DDS symptoms despite MRI changes, we diagnosed asymptomatic cerebral edema. The patient was discharged on regular intermittent HD without any neurological deficits. No further neurological disturbances were noted during 1-year follow-up. MRI findings in ESKD patients without DDS symptoms help to clarify the diagnosis of cerebral edema. In this case, the patient did not have apparent DDS symptoms and was therefore diagnosed with asymptomatic cerebral edema.

    Objective: This study was aimed to evaluate myocardial perfusion in asymptomatic patients with type 1 (DM1) and type 2 diabetes mellitus (DM2) without previous diagnoses of coronary artery disease (CAD) or cerebral infarction. Materials and Methods: Fifty-nine consecutive asymptomatic patients (16 DM1, 43 DM2) underwent myocardial perfusion scintigraphy with {sup 99m}Tc-sestamibi (MPS). They were evaluated for body mass index, metabolic control of DM, type of therapy, systemic arterial hypertension, dyslipidemia, nephropathy, retinopathy, peripheral neuropathy, smoking, and familial history of CAD. Results: MPS was abnormal in 15 patients (25.4%): 12 (20.3%) with perfusion abnormalities, and 3 with isolated left ventricular dysfunction. The strongest predictors for abnormal myocardial perfusion were: age 60 years and above (p = 0.017; odds ratio [OR] = 6.0), peripheral neuropathy (p = 0.028; OR = 6.1), nephropathy (p = 0.031; OR = 5.6), and stress ECG positive for ischemia (p = 0.049; OR = 4.08). Conclusion: Silent myocardial ischemia occurs in more than one in five asymptomatic diabetic patients. The strongest predictors of ischemia in this study were: patient age, peripheral neuropathy, nephropathy, retinopathy and a stress ECG positive for ischemia. (author)

    Full Text Available Aims: To study the prevalence of upper airway obstruction (UAO in "apparently asymptomatic" patients with euthyroid multinodular goitre (MNG and find correlation between clinical features, UAO on pulmonary function test (PFT and tracheal narrowing on computerised tomography (CT. Materials and Methods: Consecutive patients with apparently asymptomatic euthyroid MNG attending thyroid clinic in a tertiary centre underwent clinical examination to elicit features of UAO, PFT, and CT of neck and chest. Statistical Analysis Used: Statistical analysis was done with SPSS version 11.5 using paired t-test, Chi square test, and Fisher′s exact test. P value of <0.05 was considered to be significant. Results: Fifty-six patients (52 females and four males were studied. The prevalence of UAO (PFT and significant tracheal narrowing (CT was 14.3%. and 9.3%, respectively. Clinical features failed to predict UAO or significant tracheal narrowing. Tracheal narrowing (CT did not correlate with UAO (PFT. Volume of goitre significantly correlated with degree of tracheal narrowing. Conclusions: Clinical features do not predict UAO on PFT or tracheal narrowing on CT in apparently asymptomatic patients with euthyroid MNG.

    1998-01-01

    Background. MR angiography (MRA) provides a mechanism for non-invasively studying blood flow, thus providing a new opportunity to study the intracranial circulation in asymptomatic sickle cell disease (SCD) patients. Although conventional angiography is the gold standard for the depiction of vascular anatomy, this is too invasive for an asymptomatic population. Objective. To establish the range of appearances in asymptomatic SCD patients and to correlate brain MRI results (either sub-clinical abnormalities or normal brain parenchyma) with the MRA findings. Materials and methods. Brain MRI and MRA of the intracranial circulation was performed on 22 patients (13 male and 9 female, median age 7.5 years, range 1.3-20 years). Fourteen were homozygous SS and eight were SC. The median haematocrit at the time of MRI was 25.9 (range 13.8-33.3). Results. On MR imaging, four patients had infarcts in eight vascular territories (six anterior and two posterior). In 3/4 of anterior vascular territories with infarction, long (≥ 6 mm) segments of abnormal signal were seen at the internal carotid artery bifurcation with associated reduced distal flow. Short focal areas of abnormal signal were commonly seen where vessels branched, bifurcated or curved and were not associated with infarcts. These areas probably represent turbulence-related dephasing secondary to high velocity flow found in SCD. Conclusion. Long segments (≥ 6 mm) of abnormal signal with reduced distal flow correlated with sub-clinical infarction. (orig.)

    Chest computed tomography (CT) findings of nodules, ground glass opacities, and consolidations are often interpreted as representing invasive fungal infection in individuals with febrile neutropenia. We assessed whether these CT findings were present in asymptomatic individuals with acute myeloid leukemia (AML) at low risk of invasive fungal disease. A retrospective study of consecutive asymptomatic adult patients with newly diagnosed AML over a 2-year period was performed at a tertiary care oncology center. Radiology reports of baseline chest CTs were reviewed. Of 145 CT scans, the majority (88%) had pulmonary abnormalities. Many (70%) had one or both of unspecified opacities (52%) and nodules (49%). Ground glass opacities (18%) and consolidations (12%) occurred less frequently. Radiologists suggested pneumonia as a possible diagnosis in 32% (n = 47) of scans. Chest CT may result in over-diagnosis of invasive fungal disease in individuals with febrile neutropenia if interpreted without correlation to the patients' clinical status.

    The number of patients with morbid obesity is increasing worldwide. However, the prevalence of morbid obesity is still low in Japan, and therefore few systematic investigations of liver dysfunction in this population have so far been carried out. This study aimed to investigate the clinical characteristics in severe obese Japanese patients undergoing laparoscopic Roux-en-Y gastric bypass surgery (LRYGB). Eighty-four patients with severe obesity, including 61 Japanese and 23 non-Japanese patients, were analyzed. The mean body mass index (BMI) was 43.7±7.8 kg/m 2 , and there was no difference between Japanese and non-Japanese patients. Nonalcoholic fatty liver disease (NAFLD) was observed in 45/59 (76.2%) of the Japanese patients. Although there were no differences in the BMI and body weight, serum alanine aminotransferase (ALT) was higher in Japanese patients in comparison to non-Japanese patients (P<0.05). The indices for insulin resistance were significantly higher in the Japanese patients in comparison to non-Japanese patients (P<0.01). The liver/spleen computed tomography (CT) ratios were lower in Japanese patients (P<0.05). The laboratory data and BMI significantly improved at 1 year after LRYGB in both groups. Racial difference may exist difference may exist in NAFLD in patients with severe obesity. When the BMI is similar, liver dysfunction among Japanese patients with severe obesity tends to be higher than in non-Japanese patients. Japanese patients with severe obesity must therefore reduce their body weight to a greater degree in comparison to non-Japanese patients with the same BMI. LRYGB can achieve effective weight control and lower ALT levels in Japanese patients with severe obesity. (author)

  20. Asymptomatic neurocognitive disorders in patients infected by HIV: fact or fiction?

    Torti Carlo

    2011-12-01

    Full Text Available Abstract Neurocognitive disorders are emerging as a possible complication in patients infected with HIV. Even if asymptomatic, neurocognitive abnormalities are frequently detected using a battery of tests. This supported the creation of asymptomatic neurocognitive impairment (ANI as a new entity. In a recent article published in BMC Infectious Diseases, Magnus Gisslén and colleagues applied a statistical approach, concluding that there is an overestimation of the actual problem. In fact, about 20% of patients are classified as neurocognitively impaired without a clear impact on daily activities. In the present commentary, we discuss the clinical implications of their findings. Although a cautious approach would indicate a stricter follow-up of patients affected by this disorder, it is premature to consider it as a proper disease. Based on a review of the data in the current literature we conclude that it is urgent to conduct more studies to estimate the overall risk of progression of the asymptomatic neurocognitive impairment. Moreover, it is important to understand whether new biomarkers or neuroimaging tools can help to identify better the most at risk population.

    Full Text Available Osmotic demyelination syndrome leading to central pontine/extra-pontine myelinolysis (CPM/EPM occurs mainly in patients with history of alcohol abuse, malnourishment, following liver transplantation and less commonly, in association with other systemic diseases. Asymptomatic CPM/EPM is rare. Patients with end-stage renal disease (ESRD who develop CPM/EPM are usually symptomatic with florid neurologic manifestations. Herein, we present a patient with ESRD on maintenance hemodialysis who was incidentally detected to have pontine and extra-pontine lesions suggestive of myelinolysis without any neurologic signs or symptoms.

  3. LUMBAR LORDOSIS IN ASYMPTOMATICS SUBJECTS AND PATIENTS WITH CHRONIC LOW BACK PAIN

    S.J MOUSAVI

    2003-12-01

    Full Text Available Introduction: The relationship between the degree of lumbar lordosis and chronic and purpose low back pain (LBP has long been speculated, but there is discrepancy in findings of previous researchers. The purpose of this of this study was to drtermin differences between lumbar lordosis in asymptomatic and LBP subjects. Matherials: Lumbar lordosis of 420 patients with chronic LBP and 420 asymptomatic subjects was measured by two examiner. A flexible ruler was used to measure lumbar lodosis in all subjects. Results: The averagr degree of lumbar lordosis for all subjects was 37±13°. Females had greater lumbar lordosis (42 ±15° than males (32±100 and elderly subjects had lesser lumbar lordosis than younger and middle aged subjects. Conclussoion: The degree of lumbar lordosis was not differet between normal subjects and those with LBP. It seems that effects of lumbar lordosis on LBP and treatment programs need to be reevaluated.

  4. Uncommon Asymptomatic Unilateral Complete Duplicated Collecting System and Giant Ectopic Ureterocele in Middle-Age Patient

    Full Text Available Ureterocele is a common pediatric urologic problem, but has been reported seldom in adults. Most duplex system ureteroceles existent as urinary tract infections at an early age, with adult presentation being uncommon. Urinary stasis in the dilated distal ureter often lends to urinary infection and stone formation; precluding the most common offering symptoms of dysuria, urgency, and recurrent urinary tract infections. Ižn duplex system ureteroceles to poorly or non-functioning moieties, heminephroureterectomy is an definite solution. We present a case of rarely middle-age asymptomatic obstructive giant ureterocele. We intended to emphasize that patient with obstructive, giant, ectopic ureterocele and duplicated collecting system may have asymptomatic course.

    Currently available tests are unable to distinguish between asymptomatic sensitization and clinically relevant Hymenoptera venom allergy. A reliable serological marker to monitor venom immunotherapy (VIT) does also not exist. Our aim was to find reliable serological markers to predict tolerance to bee and vespid stings. We included 77 asymptomatically sensitized subjects, 85 allergic patients with acute systemic sting reactions, and 61 allergic patients currently treated with VIT. Levels of sIgE and sIgG 4 to bee and vespid venom, rApi m 1, and rVes v 5 were measured immediately after allergic sting reactions or before sting challenges and 4 weeks later. All sting challenges were tolerated. The inhibitory activity was determined using BAT inhibition and ELIFAB assay. Median sIgG 4 levels were 96-fold higher in VIT patients (P venom, but not in those treated with bee venom. Four weeks after the sting, sIgE and sIgG 4 levels were increased in allergic and asymptomatically sensitized patients, but not in VIT patients. Immunological responses after stings varied in bee and vespid venom-allergic patients. In patients under VIT, sIgE and sIgG 4 remained completely stable after sting challenges. Monitoring VIT efficacy was only possible in vespid venom allergy, and the sIgG 4 threshold for rVes v 5 had the highest sensitivity to confirm tolerance. The BAT inhibition test was the most reliable tool to confirm tolerance on an individual basis. © 2017 EAACI and John Wiley and Sons A/S. Published by John Wiley and Sons Ltd.

    2012-01-01

    Purpose: To compare perioperative and follow-up outcomes of symptomatic versus asymptomatic patients following endovascular repair of anastomotic pseudoaneurysms (APAs) of the abdominal aorta and iliac arteries. Methods: We retrospectively evaluated 17 patients (two women), with a mean age of 66.2 years (range 30–83 years). Endovascular treatment was performed in ten symptomatic, and seven asymptomatic patients electively. Data included technical success, perioperative (within 30 days) mortality and morbidity, as well as stent graft-related complications, reinterventions, and survival in follow-up. Results: Bifurcated (n = 13), aortomonoiliac (n = 3) endoprosthesis and one aortic cuff were implanted with a primary technical success rate of 100%. The overall in-hospital mortality and morbidity rate was 11.8% and 35.3%. The mean survival was 36.5 (range 0–111) months. There was a clear trend toward a lower overall survival within hospital and at one and three years for symptomatic patients compared to asymptomatic patients. (47.7 (CI: 0–138.8) versus 52.6 (CI: 28.5–76.8) months (p = 0.274)). During follow-up, late stent graft related complications were observed in six patients (35.3%) necessitating eight endovascular reinterventions. Additional three patients with primary fistulas between the APA and the intestine were treated by late surgical revision. Conclusion: Endovascular therapy of APAs represents a considerable alternative to open surgical repair. Short proximal anchoring zones still pose a risk for endoleaks and unintentional overstenting of side branches with commercially available devices, but this might be overcome by use of fenestrated and branched stent grafts in elective cases.

    2014-01-01

    Background Endovascular treatment of internal carotid artery stenosis (ICAS) has gained popularity in recent years. Offering CAS, which is a controversial treatment in asymptomatic disease, may provoke patient distrust of the diagnosis and intervention benefit. The aim of this study was to prove that asymptomatic ICAS patients tend to show an emotional attitude to their illness, and therefore their decisions regarding carotid artery stenting are externally motivated and assessed emotionally. ...

  9. Sarcoidal granuloma presenting on tattoo: a report of a Japanese female patient and a review of Japanese published work.

    Ohtsuka, Mikio; Natsuko, Matsumura; Toshiyuki, Yamamoto

    2016-03-29

    Cases of tattoo sarcoidosis reported in English and French literature have recently been reviewed; however, only two Japanese patients were included in the review because most Japanese patients were reported in Japanese journals. To determine the clinical characteristics of Japanese tattoo sarcoidosis. We reported a Japanese female with tattoo sarcoidosis, and reviewed the cases of tattoo sarcoidosis reported in Japanese literature. A 27-year-old Japanese female presented with skin nodules on a tattoo. She was diagnosed as having systemic sarcoidosis by skin biopsies and systemic work-up. We identified twelve cases, including ours, with tattoo sarcoidosis reported in Japanese journals, and revealed that these cases showed clinical features closely similar to those of Japanese sarcoidosis without tattoo in terms of the onset age distributions, incidence of extracutaneous organ involvement, and laboratory abnormalities. In comparison with cases of other races, Japanese tattoo sarcoidosis was revealed to have a higher prevalence of uveitis, which might be attributable to genetic background, as incidence and organ involvement may vary from race to race. Our results suggest that a tattoo does not have significant impact on the clinical features of sarcoidosis. However, skin lesions on a tattoo can be the first sign of systemic sarcoidosis in any race; therefore, much attention should be paid to skin eruptions on a tattoo for earlier identification of patients who need work-up for systemic illness.

    Lee, Sun Hee; Jung, Ji Mi; Song, Min Seob; Choi, Seok jin; Chung, Woo Yeong

    2013-08-01

    Turner syndrome is well known to be associated with significant cardiovascular abnormalities. This paper studied the incidence of cardiovascular abnormalities in asymptomatic adolescent patients with Turner syndrome using multidetector computed tomography (MDCT) instead of echocardiography. Twenty subjects diagnosed with Turner syndrome who had no cardiac symptoms were included. Blood pressure and electrocardiography (ECG) was checked. Cardiovascular abnormalities were checked by MDCT. According to the ECG results, 11 had a prolonged QTc interval, 5 had a posterior fascicular block, 3 had a ventricular conduction disorder. MDCT revealed vascular abnormalities in 13 patients (65%). Three patients had an aberrant right subclavian artery, 2 had dilatation of left subclavian artery, and others had an aortic root dilatation, aortic diverticulum, and abnormal left vertebral artery. As for venous abnormalities, 3 patients had partial anomalous pulmonary venous return and 2 had a persistent left superior vena cava. This study found cardiovascular abnormalities in 65% of asymptomatic Turner syndrome patients using MDCT. Even though, there are no cardiac symptoms in Turner syndrome patients, a complete evaluation of the heart with echocardiography or MDCT at transition period to adults must be performed.

  11. Frequency of hepatitis B in asymptomatic patients of district Headquarter hospital Kotli, Azad Kashmir

    Sarwar, J.; Ahmad, W.; Saleem, M.; Jamshed, F.; Gul, N.; Idrees, M.

    2010-01-01

    Background: Hepatitis B is prevalent throughout the world including Pakistan. A large proportion of patients suffering from Hepatitis B may be asymptomatic and can transmit the disease to healthy population. Objectives of this study were to estimate the frequency of Hepatitis B in asymptomatic adult population coming to District Headquarter Hospital Kotli, Azad Kashmir and to determine the risk factors associated with its transmission. Methods: This was a cross-sectional study extending from January to December 2008. Subjects were randomly selected from those who attended the medial OPD of DHQ Hospital Kotli, Azad Kashmir for non-Hepatitis related problems. Both males and females between the ages of 15-80 years were included in the study. Blood samples taken from selected subjects were analysed for Hepatitis B surface antigen (HBsAg) by Immuno chromatographic kit methods (ICT). Hepatitis B positive samples were further confirmed by third generation ELIZA. The patients thus confirmed were interrogated for different risk factors associated with transmission of Hepatitis B. Results: A total of 9,564 patients were analysed. Out of them 4230 (44.22%) were males and 5334 (55.77%) were females. Overall 141 (1.47%) patients were positive for HBSAg, 71 (1.68%) males and 70 (1.31%) females. Patients between 21-30 years of age were most commonly effected (35.46%, n=50). Blood transfusion was the most common risk factor (24.82%, n=35) associated with Hepatitis B transmission followed by dental procedures (14.18%, n=20). Conclusion: Frequency of Hepatitis B in asymptomatic people in this study was quite high. Blood transfusions and dental procedures were the most common risk factors associated with the transmission of Hepatitis B. (author)

  12. Bleeding and asymptomatic overdose in patients under Vitamin K antagonist therapy: Frequency and risk factors

    F. Ben Mbarka

    2018-03-01

    Full Text Available Background: Vitamin K antagonists are widely used in the treatment and prevention of thromboembolic disease. However, these drugs can cause serious side effects, especially bleeding. This study aims to evaluate frequency and risk factors of both bleeding and asymptomatic overdose in North African patients undergoing Vitamin K antagonist therapy. Methods: We performed a cross-sectional study in patients undergoing Vitamin K antagonist therapy. A statistical analysis has been conducted to identify overdose and bleeding risk factors by using chi-square test (p < .05. Results: One hundred and eleven patients were included. We recorded 14 cases of bleeding and 26 cases of asymptomatic overdose. Advanced age, poor adherence, concomitant use of paracetamol and history of previous bleeding are significant risk factors of over-anticoagulation. An INR value over 6 at admission, a high therapeutic target range for INR, concomitant use of acetylsalicylic acid, lack of information on overdose signs and measures to be taken in case of bleeding were identified as risk factors for bleeding. Conclusion: Most of the risk factors identified in our study seem to be related to patients lack of information and education. These results highlight the importance of creating a therapeutic patient education program. Keywords: Vitamin K antagonist, Bleeding, Risk factor, Overdose

    1998-01-01

    There is no specific agreement in the literature about the benefit of the use of abdominal ultrasound in the study asymptomatic adult patients. Based on the abdominal ultrasounds done to patient of the executive medical check-up program at the Foundation Santafe de Bogota (FSFB), we carried out a study to determine the prevalence of diseases detected by the abdominal ultrasound, the possibility that these modified the course of the disease and the cost-benefit relationship of the ultrasound in asymptomatic patients. We carried out a descriptive study with a series of cases, 500 medical charts of the executive medical check-up program at the FSFB. Were reviewed, 489 (97.8%) of these patient underwent abdominal ultrasound. the sample was distributed in 390 (78%) men and 110 (22%) women, the average age was 43.4 years. we found 216 (44.2%) patients with abnormal findings and an overall 315 positive findings. the main findings detected in ultrasound were not significant from the clinical point of view. the most common finding was liver fatty infiltration 138 (43.8%), which had statistically significant relationship with the abnormal serum of total cholesterol, high density cholesterol and triglycerides

  14. The Association between Myocardial Iron Load and Ventricular Repolarization Parameters in Asymptomatic Beta-Thalassemia Patients

    2012-01-01

    Full Text Available Previous studies have demonstrated impaired ventricular repolarization in patients with β-TM. However, the effect of iron overload with cardiac T2* magnetic resonance imaging (MRI on cardiac repolarization remains unclear yet. We aimed to examine relationship between repolarization parameters and iron loading using cardiac T2* MRI in asymptomatic β-TM patients. Twenty-two β-TM patients and 22 age- and gender-matched healthy controls were enrolled to the study. From the 12-lead surface electrocardiography, regional and transmyocardial repolarization parameters were evaluated manually by two experienced cardiologists. All patients were also undergone MRI for cardiac T2* evaluation. Cardiac T2* score <20 msec was considered as iron overload status. Of the QT parameters, QT duration, corrected QT interval, and QT peak duration were significantly longer in the β-TM group compared to the healthy controls. Tp−Te and Tp−Te dispersions were also significantly prolonged in β-TM group compared to healthy controls. (Tp-Te/QT was similar between groups. There was no correlation between repolarization parameters and cardiac T2* MRI values. In conclusion, although repolarization parameters were prolonged in asymptomatic β-TM patients compared with control, we could not find any relation between ECG findings and cardiac iron load.

    Aims: To study the prevalence of upper airway obstruction (UAO) in “apparently asymptomatic” patients with euthyroid multinodular goitre (MNG) and find correlation between clinical features, UAO on pulmonary function test (PFT) and tracheal narrowing on computerised tomography (CT). Materials and Methods: Consecutive patients with apparently asymptomatic euthyroid MNG attending thyroid clinic in a tertiary centre underwent clinical examination to elicit features of UAO, PFT, and CT of neck and chest. Statistical Analysis Used: Statistical analysis was done with SPSS version 11.5 using paired t-test, Chi square test, and Fisher's exact test. P value of <0.05 was considered to be significant. Results: Fifty-six patients (52 females and four males) were studied. The prevalence of UAO (PFT) and significant tracheal narrowing (CT) was 14.3%. and 9.3%, respectively. Clinical features failed to predict UAO or significant tracheal narrowing. Tracheal narrowing (CT) did not correlate with UAO (PFT). Volume of goitre significantly correlated with degree of tracheal narrowing. Conclusions: Clinical features do not predict UAO on PFT or tracheal narrowing on CT in apparently asymptomatic patients with euthyroid MNG. PMID:21966649

    To determine the frequency of asymptomatic spontaneous bacterial peritonitis in patients of liver cirrhosis with ascites. Study Design: Descriptive study. Place and Duration of Study: The study was conducted at indoor and outpatient departments of Medicine, Military Hospital, Rawalpindi, pakistan from 29th February 2008 to 28th August 2008. Subject and Methods: One hundred and ninety five patients of liver cirrhosis with ascites were selected. To standardize the study; patients of both genders over 18 years of age, diagnosed with liver cirrhosis and ascites were included in the study after obtaining their informed consent. Patients with abdominal tenderness and fever, hepatic encephalopathy, intra-abdominal surgically treatable cause, with any co-morbid disease (hypertension and diabetes mellitus) or refusing to give consent were excluded from the study. Strict inclusion/exclusion criteria were observed to control the confounding variables. Diagnosis of spontaneous bacterial peritonitis was based on increased ascitic fluid absolute polymorphonuclear leukocyte (PMN) count ( 250 cells / mm3) and/or positive bacterial culture. Results: Out of 195 patients, 10 patients (5%) had neutrocytic ascites (absolute neutrophil count = 250 cell/mm3). Out of these 195 patients, three patients (1.5%) were found to have positive ascitic fluid culture. Conclusion: In our study the frequency of asymptomatic spontaneous bacterial peritonitis in patients of liver cirrhosis with ascites turned out to be 5% which is low. Therefore, analysis of ascitic fluid through diagnostic paracentesis should be reserved for inpatient or outpatient with clinically apparent new onset ascities or in cirrhotic patients with ascities whose general condition deteriorates.

  17. Frequency of hepatitis C in asymptomatic patients in district headquarters hospital Kotli, Azad Kashmir

    Saleem, M.; Ahmad, W.; Sarwar, J.

    2011-01-01

    Background: Hepatitis C is a common problem in developing world. It can affect a large number of asymptomatic people in whom it may cause serious complications in long run. Moreover, these asymptomatic infected people pose a serious risk for the transmission of infection to healthy population. Objective of this study was to estimate the frequency of Hepatitis C in asymptomatic adult patients attending medical OPD of District Headquarters Hospital Kotli, Azad Kashmir, and to assess the risk factors associated with its transmission. Methods: This was a cross-sectional study that included asymptomatic patients of both genders, aged 15-80 years, attending medical OPD of District Head quarter Hospital Kotli, Azad Kashmir from January to December, 2008. They attended the OPD for problems other than Hepatitis and most of them presented with vague complaints like generalised body aches, tiredness and dyspeptic symptoms. They were randomly tested for Hepatitis C virus (HCV) antibodies by Immuno chromatographic kit method. Positive samples for Hepatitis C antibodies were confirmed by third generation ELISA. Those who were confirmed were assessed for the risk factors associated with HCV transmission. Results: The study included 9,564 patients. Out of them 4,2 (44.22%) were males and 5,334 (55.77%) were females. A total of 611 (6.38%) cases were positive for HCV; 257 (6.08%) were males, and 354 (6.64%) were females. Highest frequency (36%) was found between 21 and 30 years of age, and 60.54% positive patients were 21-40 years old. Blood transfusion was the most common (34.36%) risk factor followed by history of dental procedures (24.54%). In 27.16% no risk factor could be detected. Conclusion: Frequency of Hepatitis C is quite high in our population. Rate is higher in young adults. It is needed to adopt organised preventive strategies to overcome this problem. Blood transfusion is still the most significant risk factor followed by dental and surgical procedures. Health related

  18. Asymptomatic Chiari Type I malformation: should patients be advised against participation in contact sports?

    Spencer, Robert; Leach, Paul

    2017-08-01

    Chiari type I malformation (CM-I) is characterised by caudal displacement of the cerebellar tonsils through the foramen magnum, crowding the craniocervical junction. It is being increasingly diagnosed in asymptomatic patients due to the widespread availability of MRI, and there are case reports of these patients suffering sudden death or neurological injury following head or neck trauma, raising the issue of whether they should be prohibited from contact sport participation, given the likelihood of frequent trauma. General neurosurgical opinion is that patients who are symptomatic and those with an associated spinal cord syrinx should be offered foramen magnum decompression, however asymptomatic patients without syringomyelia are not offered this in the majority of cases. The authors performed a full review of the published literature, including all case reports, case series, studies and literature reviews regarding CM-I and either contact sports or trauma, excluding patients that had undergone surgical intervention and those becoming symptomatic in circumstances other than head or neck trauma. 21 case reports of CM-I patients deteriorating following trauma were identified, including four cases of sudden death following head or neck injury. However, studies of large samples of CM-I patients are yet to capture an incident of sudden death or acute neurological deterioration, suggesting that the risk is very low. CM-I patients may have an increased risk of concussion and post-concussion syndrome compared to the background population however. Overall, the authors feel that there should be no restriction of sports participation for CM-I patients, but a discussion to make them and their families aware of the possible increased risks is important.

  19. Scrub typhus masquerading as HELLP syndrome and puerperal sepsis in an asymptomatic malaria patient.

    Scrub typhus and malaria can involve multiple organ systems and are notoriously known for varied presentations. However, clinical malaria or scrub typhus is unusual without fever. On the other hand, altered sensorium with or without fever, dehydration, hemorrhage and hemolysis may lead to low blood pressure. Presence of toxic granules and elevated band forms in such patients can even mimic sepsis. When such a patient is in the peripartum period, it creates a strong clinical dilemma for the physician especially in unbooked obstetric cases. We present such a case where a 26-year-old unbooked female presented on second postpartum day with severe anemia, altered sensorium, difficulty in breathing along with jaundice and gum bleeding without history of fever. Rapid diagnostic test for malaria was negative and no eschar was seen. These parameters suggested a diagnosis of HELLP (Hemolysis, Elevated Liver enzymes, Low Platelet) syndrome with or without puerperal sepsis. Subsequently she was diagnosed as having asymptomatic malaria and scrub typhus and responded to the treatment of it. The biochemical changes suggestive of HELLP syndrome also subsided. We present this case to emphasize the fact that mere absence of fever and eschar does not rule out scrub typhus. It should also be considered as a differential diagnosis in patients with symptoms and signs suggesting HELLP syndrome. Asymptomatic malaria can complicate case scenario towards puerperal sepsis by giving false toxic granules and band form in such situations.

    2005-01-01

    A radiographic study was conducted to determine the incidence of redundant nerve roots of the cauda equina (RNR) in neurologically asymptomatic patients, and to clarify whether RNR has an impact on the clinical symptom. 50 patients who had spine disease such as spondylosis and compression fracture were examined by MRI. They didn't have neurological symptom such as sciatica, leg numbness, and motor weakness of lower extremities. There were 18 men and 32 women, and their mean age was 72.4 years (range: 32-87 years). RNR was found in 18 of the 50 patients (36.0%) and in a higher percentage of the patients who had lumber spinal canal stenosis. We concluded that RNR was only a morphological change of the cauda equine and had little effect on the neurological symptom. (author)

    Bar-Shalom, Dana; Poulsen, Mikael K; Rasmussen, Lars M

    2014-01-01

    Recently, copeptin was found associated with cardiovascular disease (CVD) and all-cause mortality in type 2 diabetes mellitus (T2DM) patients treated in primary care. This study aimed to evaluate whether plasma copeptin correlated to CVD in asymptomatic T2DM patients intensively investigated....... A variety of clinical investigations were performed, including blood pressure measurements, carotid intima media thickness evaluation and myocardial perfusion scintigraphy. Blood sample analyses included copeptin measurements. Median plasma copeptin concentrations were similar in the T2DM group...... for sub-clinical CVD. A total of 302 T2DM patients referred to the Diabetes Clinic at Odense University Hospital, Denmark, entered the study. None of the patients had known or suspected CVD.

    Keeling, Aoife N

    2009-09-01

    The clinical importance of angiographically detected asymptomatic lower-limb stenoses and occlusions is unknown. This study aims to (i) assess the clinical outcome of asymptomatic lesions in the lower limb, (ii) identify predictors of clinical deterioration, and (iii) determine which asymptomatic lower-limb lesions should be treated at presentation.

  3. Dysregulation of coronary microvascular reactivity in asymptomatic patients with type 2 diabetes mellitus

    2002-12-01

    In diabetic patients, a number of studies have suggested an impairment of vascular reactivity in response to vasodilatory stimuli. The pattern of dysregulation at the coronary microcirculatory level, however, has not been clearly defined. Thus, it was the aim of this study to characterise coronary microvascular function non-invasively in a homogeneous group of asymptomatic type 2 diabetic patients. In 46 patients with type 2 diabetes, myocardial blood flow (MBF) was quantified at baseline, in response to cold pressor test (CPT) and during adenosine-mediated vasodilation using positron emission tomography and nitrogen-13 ammonia. None of the patients had been treated with insulin, and none had symptoms of cardiac disease. Decreased MBF during CPT, indicating microvascular dysregulation, was observed in 16 patients (CPT-), while 30 patients demonstrated increased MBF during CPT (CPT+). Response to CPT was mildly, but significantly correlated with response to adenosine (r=0.44, P=0.0035). There was no difference in HbA1c, serum lipid levels or serum endothelial markers between the groups. Microvascular dysregulation in the CPT- group was associated with elevated baseline MBF (P<0.0001), reduced baseline vascular resistance (P=0.0026) and an abnormal increase in resistance during CPT (P=0.0002). In conclusion, coronary microvascular dysregulation is present in approximately one-third of asymptomatic, non-insulin-treated type 2 diabetic patients. Elevated baseline blood flow and reduced microvascular resistance at rest are characteristics of this dysregulation. These data suggest a state of activation of endothelial-dependent vasodilation at baseline which appears to limit the flow response to stress conditions. (orig.)

    2013-01-01

    Context Compared to whites, Black men and women have a higher incidence and mortality from colorectal cancer and may develop cancer at a younger age. Colorectal cancer screening might be less effective in Blacks, if there are racial differences in the age-adjusted prevalence and location of cancer precursor lesions. Objectives To determine and compare the prevalence rates and location of polyp(s) >9mm in asymptomatic Blacks and whites who receive colonoscopy screening. Design, Setting, and Patients Colonoscopy data were prospectively collected from 67 practice sites in the United States using a computerized endoscopic report generator from 2004–2005. Data were transmitted to a central data repository, where all asymptomatic whites (n = 80,061) and Blacks (n = 5464) who received screening colonoscopy were identified. Main outcome measures Prevalence and location of polyp(s) >9mm, adjusted for age, gender, and family history of colorectal cancer in a multivariate analysis. Results Both Black men and women had a higher prevalence of polyp(s) >9mm (7.7 versus 6.2%; p 9mm (OR 1.133; 95% CI 0.93,1.38). However, in a sub-analysis of patients over age 60 years, proximal polyps >9mm were more likely in Black men (p = 0.026) and women (p9mm, and Black over age 60 years are more likely to proximal polyps >9mm.

  5. Subclinical Coronary Plaque Burden in Asymptomatic Relatives of Patients With Documented Premature Coronary Artery Disease

    Christiansen, Morten Krogh; Jensen, Jesper Møller; Bøtker, Hans Erik

    Introduction: A family history of premature coronary artery disease (CAD) is a well-known risk factor for adverse coronary events with age of onset being inversely related to the degree of heritability. Hypothesis: We hypothesized that asymptomatic first degree relatives, of patients with premature...... CAD, suffer a high burden of subclinical coronary atherosclerosis. Methods: First degree relatives, aged 30-65 years, of patients with a documented coronary revascularization procedure before the age of 40 years, were invited to participate in the study. Participants were matched by age, sex...... and absence of a family history, with patients referred for coronary CT angiography (CTA) because of atypical angina or non-anginal chest pain. A pooled blinded analysis was performed. The main outcome measure was the number of plaque-affected coronary segments. Results: 88 relatives and 88 symptomatic...

    2006-01-01

    To evaluate the prevalence of coronary artery disease (CAD) in patients with spinal cord injury (SCI), 47 clinically asymptomatic SCI patients received thallium-201 myocardial perfusion single photon emission computed tomography (Tl-201 SPECT) after dipyridamole administration for the diagnosis of CAD. There were 4 groups as follows; group 1: 13 patients with quadriplegia and complete SCI, group 2: 11 patients with quadriplegia and incomplete SCI, group 3: 11 patients with paraplegia and complete SCI, and group 4: 12 patients with paraplegia and incomplete SCI. There were no significant differences in sex distribution, ages, SCI duration, or CAD risk factors among the SCI patients in the 4 groups. All Tl-201 SPECT images were interpreted by the agreement of 2 experienced nuclear medicine physicians without prior knowledge of the patients' histories. A total of 30 of 47 (63.8%) SCI patients had abnormal Tl-201 SPECT findings. Among the 4 groups of SCI patients, those in groups 1 and 4 had the significantly highest and lowest prevalences of abnormal Tl-201 SPECT findings, respectively. We concluded that combined quadriplegia and complete SCI is an important CAD risk factor in SCI patients based on the objective evidence of intravenous dipyridamole cardiac stress testing with Tl-201 SPECT.

  7. Evaluation of Asymptomatic Peripheral Arterial Disease by Ankle-brachial Index in Patients with Concomitant Coronary Arterial Disease

    Hosein Vakili

    2012-12-01

    Full Text Available Background: Peripheral arterial disease is associated with adverse cardiovascular outcomes. As such, it is found that screening for peripheral arterial disease (PAD improves risk assessment. Thus, intensive risk factor modification and medical treatment in these patients are necessary. Objectives: The purpose of this study was to determine the prevalence of asymptomatic peripheral arterial disease in patients with concomitant coronary arterial disease. Methods: Asymptomatic peripheral arterial disease was investigated in 400 patients (60% males, 40% females, aged 59.7± 11.3 with a documented coronary arterial disease. Results: Among patients with documented CAD, 12% had asymptomatic PAD with the ABI ratio of less than 0.9. Conclusions: It is advisable to screen for PAD not only as a disease but also as a risk assessment method for atherosclerosis.

    1989-01-01

    To investigate the significance of the electrocardiographic (ECG) pattern of left ventricular hypertrophy and strain, two groups of asymptomatic patients with essential hypertension were compared. The patients were similar in terms of age, smoking habit, serum cholesterol and blood pressure levels, but differed in the presence (Group I, n = 23) or absence (Group II, n = 23) of the ECG pattern of left ventricular hypertrophy and strain. Group I patients had significantly more episodes of exercise-induced ST segment depression (14 versus 4, p less than 0.05) and reversible thallium perfusion abnormalities (11 of 23 versus 3 of 23, p less than 0.05) despite similar exercise capacity and absence of chest pain. Nonsustained ventricular tachycardia was detected on 24 h ambulatory ECG monitoring in two patients in Group I, but no patient in Group II. Coronary arteriography performed in 20 Group I patients demonstrated significant coronary artery disease in 8 patients. This study has shown that there is a subgroup of hypertensive patients with ECG left ventricular hypertrophy and strain who have covert coronary artery disease. This can be detected by thallium perfusion scintigraphy, and may contribute to the increased risk known to be associated with this ECG abnormality

    To determine the factors associated with thyroid cancer, focusing on first-degree family history and ultrasonography (US) features, in euthyroid asymptomatic patients with thyroid nodules. This retrospective study included 1310 thyroid nodules of 1254 euthyroid asymptomatic patients who underwent US-guided fine-needle aspiration biopsy between November 2012 and August 2013. Nodule size and clinical risk factors- such as patient age, gender, first-degree family history of thyroid cancer, multiplicity on US and serum thyroid stimulating hormone (TSH) levels - were considered together with US features to compare benign and malignant nodules. Multiple logistic regression analysis was performed to assess the risk of thyroid malignancy according to clinical and US characteristics. Although all of the clinical factors and US findings were significantly different between patients with benign and malignant nodules, a solitary lesion on US (p = 0.041–0.043), US features and male gender (p < 0.001) were significant independent risk factors for thyroid malignancy in a multivariate analysis. Patient age, a first-degree family history of thyroid cancer and high normal serum TSH levels did not independently significantly increase the risk of thyroid cancer. However, multicollinearity existed between US assessment and patient age, first-degree family history of thyroid cancer and serum TSH values. Ultrasonography findings should be the primary criterion used to decide the management of euthyroid asymptomatic patients with thyroid nodules. The concept of first-degree family history as a risk factor for thyroid malignancy should be further studied in asymptomatic patients

  13. Carboplatin Dosing for Adult Japanese Patients

    ANDO, YUICHI; SHIMOKATA, TOMOYA; YASUDA, YOSHINARI; HASEGAWA, YOSHINORI

    2014-01-01

    ABSTRACT 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...

  14. Understanding Patients' Preferences for Referrals to Specialists for an Asymptomatic Condition.

    Dunlea, Robert; Lenert, Leslie

    2015-01-14

    A specialty referral is a common but complex decision that often requires a primary care provider to balance his or her own interests with those of the patient. To examine the factors that influence a patient's choice of a specialist for consultation for an asymptomatic condition and better understand the tradeoffs that patients are and are not willing to make in this decision. Stratified cross-sectional convenience sample of subjects selected to parallel US population demographics. Members of an Internet survey panel who reported seeing a physician in the past year whose responses met objective quality metrics for attention. Respondents completed an adaptive conjoint analysis survey comparing specialists regarding eight attributes. The reliability of assessments and the predictive validity of models were measured using holdout samples. The relative importance (RI) of different attributes was computed using paired t tests. The implications of utility values were studied using market simulation methods. Five hundred and thirty subjects completed the survey and had responses that met quality criteria. The reliability of responses was high (86% agreement), and models were predictive of patients' preferences (82.6% agreement with holdout choices). The most important attribute for patients was out-of-pocket cost (RI of 19.5%, P communication" with the primary care provider was the most important attribute (RI of 13.1% P importance was whether the specialist practiced shared decision making (RI of 12.2% P well with their primary care provider and practiced shared decision making. Most patients prefer to wait for a doctor who practices shared decision making: Only one-third (32.3%) of patients preferred a paternalistic doctor who was available in 2 weeks over a doctor who practiced decision making but was available in 4 weeks. In the setting of a referral for an asymptomatic but serious condition, out-of-pocket costs are important to patients; however, they also value

    2009-05-01

    The present study was aimed to test the association between asymptomatic bacteriuria during pregnancy, among patients in whom antibiotic treatment was recommended, and perinatal outcome. Our study was also designed to characterize common bacteria and risk factors associated with asymptomatic bacteriuria during pregnancy. A retrospective population-based study comparing all singleton pregnancies of women with and asymptomatic bacteriuria was conducted. Patients with urinary tract infection were excluded from the analysis. Multiple logistic regression model was used to control for confounders. Out of 199,093 deliveries, 2.5% (n = 4890) were in patients with asymptomatic bacteriuria. E. coli was the most common pathogen associated with asymptomatic bacteriuria, representing 78.6% of the cultures with specified growth. Patients with asymptomatic bacteriuria were more likely to deliver preterm (PTD, 13.3%vs. 7.6%, odd ratio (OR) = 1.9, 95% confidence interval CI 1.7-2.0; P Asymptomatic bacteriuria was independently associated with PTD (adjusted OR = 1.6; 95% CI 1.5-1.7; P treatments, hypertensive disorders, recurrent abortions, diabetes mellitus, intrauterine growth restriction, polyhydramnion and oligohydramnion, premature rupture of membranes and labour induction, in a multivariable analysis with backwards elimination. Perinatal mortality rates (1.5%vs. 1.4%; P = 0.707) as well as low 5 min Apgar scores (0.8%vs. 0.6%; P = 0.065) were comparable between the groups. Asymptomatic bacteriuria is an independent risk factor for preterm delivery.

    1993-01-01

    Between 1983 and 1990, 332 patients with non-small cell lung cancer (NSCLC) were referred to short-time, split-course palliative thoracic radiotherapy. The group consisted of patients with locally advanced (III o ), unresectable cancer, not suitable for curative radiotherapy, asymptomatic or having only minimal symptoms related to intrathoracic tumor. The therapeutic plan involved two series of irradiation. Tumor dose delivered in each series was 20 Gy given in five daily fractions over five treatment days. There were four weeks interval between series. Of 332 patients initially qualified to thoracic radiotherapy only 170 patients received the treatment; the other 162 patients were not irradiated because of treatment refusal or logistic problems concerning therapy. They made the control group of the study, receiving the best possible symptomatic care. Twelve-month survivals in the radiotherapy and control groups were 32.4% and 9.3%, respectively; 24-month survivals 11.2% and 0%, respectively. Improvement of survival after palliative thoracic radiotherapy was observed only in patients with clinical stage IIIA and Karnofsky's performance status (KPS) ≥ 70. (orig.) [de

  17. Cardiac auscultation poorly predicts the presence of valvular heart disease in asymptomatic primary care patients.

    Cardiac auscultation is a key clinical skill, particularly for the diagnosis of valvular heart disease (VHD). However, its utility has declined due to the widespread availability of echocardiography and diminishing emphasis on the importance of clinical examination. We aim to determine the contemporary accuracy of auscultation for diagnosing VHD in primary care. Cardiac auscultation was undertaken by one of two experienced general practitioners (primary care/family doctors) in a subset of 251 asymptomatic participants aged >65 years undergoing echocardiography within a large community-based screening study of subjects with no known VHD. Investigators were blinded to the echocardiographic findings. Newly detected VHD was classified as mild (mild regurgitation of any valve or aortic sclerosis) or significant (at least moderate regurgitation or mild stenosis of any valve). Newly identified VHD was common, with mild disease in 170/251 participants (68%) and significant disease in 36/251 (14%). The sensitivity of auscultation was low for the diagnosis of mild VHD (32%) but slightly higher for significant VHD (44%), with specificities of 67% and 69%, respectively. Likelihood ratios were not statistically significant for the diagnosis of either mild or significant VHD in the overall cohort, but showed possible value for auscultation in non-overweight subjects (body mass index auscultation has limited accuracy for the detection of VHD in asymptomatic patients and is a poor diagnostic screening tool in primary care, particularly for overweight subjects. Ensuring easy access to echocardiography in patients with symptoms suggesting VHD is likely to represent a better diagnostic strategy. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  20. Radionuclide ventriculographic evaluation of exercised left ventricular performance in asymptomatic diabetic patients

    Fujii, Yusuke; Hara, Fumio

    1991-01-01

    Radionuclide ventriculography was made in 49 asymptomatic diabetic patients, aged 30∼70 years, to investigate cardiac function. Comparisons were made with 33 age- and sex-matched non-diabetic controls. Radionuclide ventriculography was performed at rest and during dynamic exercise by multigraded, supine bicycle ergometer. The resting left ventricular ejection fractions were similar between the diabetic patients and control subjects. No significant rise in the left ventricular ejection fractions during dynamic exercise was observed in the diabetic patients [58.4±9.8% (mean±SD) to 60.3±9.9]. In the control subjects, the left ventricular ejection fractions increased during dynamic exercise [59.3±8.4 to 63.0±11.4 (p -1 ) vs -2.66±0.52] and during dynamic exercise [-3.25±0.74 vs -3.23±0.90]. Time to end-systole were similar in both groups at rest [315±42 (ms) vs 309±42] and during dynamic exercise [258±37 vs 262±37]. The resting peak filling rates were similar in both groups [2.27±0.62 (s -1 ) vs 2.45±0.58], and the peak filling rates increased (p 1c in the diabetic patients. These results suggest that diabetic patients have less cardiac reserved performance. (author)

    2018-03-01

    The objective of this study was to perform a quantitative analysis and to identify predictors of embolic filter debris (EFD) load during carotid artery stenting (CAS) in asymptomatic patients. All patients with asymptomatic carotid stenosis >70% undergoing CAS between 2008 and 2016 were included in a prospective database. A distal filter protection device was used in all patients. At the end of the procedure, the filter was fixed in formalin and then analyzed with a stereomicroscope. Morphometric analysis was performed with Image-Pro Plus software (Media Cybernetics, Rockville, Md). The total area of the filter membrane and the area covered by particulate material were quantified. The quantity of membrane occupied by debris was expressed as percentage of covered surface area. Anatomic and clinical variables were evaluated for their association with EFD load using multiple logistic regression. Among the 278 patients undergoing CAS, an open-cell stent was implanted in 211 patients (76%); 67 patients (24%) received a closed-cell stent. Overall technical success and clinical success were both 99%; no perioperative death was reported. Stroke rate was 1.8% (major, n = 1 [0.4%]; minor, n = 4 [1.4%]); transient ischemic attacks occurred in 5% of cases (n = 14). The quantitative analysis of the filter revealed that EFD was present in 74% of cases (n = 207). The mean EFD load was 10% of the filter surface (median, 1; range, 0-80); it was 31% in 22 (8%). Patients with any type of ischemic neurologic event after CAS (stroke and transient ischemic attack) had a significantly higher mean EFD load compared with uneventful cases (26.7% ± 19.0% vs 8.5% ± 13.5%; P 12.5% EFD load as the optimal cutoff for the association with clinically relevant perioperative ischemic events (sensitivity, 78%; specificity, 77%; area under the curve, 0.81). The multivariate analysis demonstrated that age >75 years (odds ratio [OR], 2.56; P = .003), pre-existing ipsilateral ischemic

  2. Analysis of symptomatic and asymptomatic primary root canal infections in adult Norwegian patients.

    Rôças, Isabela N; Siqueira, José F; Debelian, Gilberto J

    2011-09-01

    This molecular study analyzed the microbiota of primary root canal infections from adult Norwegian patients. Samples were taken from the necrotic root canals of teeth with symptomatic (n = 13) or asymptomatic (n = 21) apical periodontitis and chronic apical abscesses (n = 9). DNA was extracted from samples, and bacterial identifications were performed by a closed-ended reverse-capture checkerboard approach targeting 50 candidate endodontic pathogens. Bacterial DNA was detected in all cases. In teeth with asymptomatic apical periodontitis, the most frequent taxa were Dialister invisus (71%), Fusobacterium nucleatum (62%), and Porphyromonas endodontalis (62%). In chronic apical abscesses, the most prevalent taxa were P. endodontalis (100%), D. invisus (89%), Parvimonas micra (78%), and Solobacterium moorei (78%). In teeth with symptomatic apical periodontitis, the most prevalent taxa were D. invisus, P. endodontalis, S. moorei, Propionibacterium acnes, and Streptococcus species (all in 69%). None of the targeted taxa were significantly associated with either sinus tract or pain (P > .05), except for Selenomonas sputigena, which was more frequently found in painful cases (P = .04). No taxa were found in significantly higher levels in any conditions (P > .05). Cluster analyses revealed bacterial groupings that differed between cases with and without pain. Although basically the same species were highly prevalent in the different conditions examined and none of the most prevalent taxa were positively associated with symptoms, results revealed that species formed different partnerships and associations in samples from teeth with or without pain. Therefore, it is possible that more virulent multispecies communities can form as a result of overall bacterial combinations and give rise to acute inflammation.

    2012-12-20

    For asymptomatic patients with moderate-severe valvular heart disease, in whom symptoms may be obscured, objective exercise tolerance measures are warranted for decisions concerning physical activities and surgical treatment. We compared 61 patients (39 with aortic stenosis, 22 with aortic or mitral regurgitation) to 23 controls without valvular heart disease but with indications for stress testing. All participants underwent cardiopulmonary function testing and dobutamine stress echocardiography. Blood was drawn before as well as after bicycle stress to assess high-sensitivity cardiac troponin T (hscTnT). Patients who underwent surgery were re-evaluated 1.5 ±0.9 years after the operation. Conventional bicycle test following guideline criteria revealed a pathologic result in 26% of the patients, whereas spiroergometry showed an objectively reduced exercise tolerance in 59%, reaching a prognostically relevant feature in 39%. Stress echocardiography detected a reduced systolic reserve in 33% and elevated filling pressures in 62%. These abnormalities were significantly less present in the control group (4, 17, 9, 9, 4% respectively, p valvular heart disease beyond stress-test criteria recommended in recent guidelines. High-sensitivity cardiac troponin I may be of additional value. Results of these tests presage post-operative function.

  4. Incidence of missed inferior alveolar nerve blocks in vital asymptomatic subjects and in patients with symptomatic irreversible pulpitis.

    Fowler, Sara; Reader, Al; Beck, Mike

    2015-05-01

    The purpose of this retrospective study was to determine the incidence of missed inferior alveolar nerve (IAN) blocks by using a 1- or 2-cartridge volume of 2% lidocaine with 1:100,000 epinephrine in vital asymptomatic teeth and in emergency patients with symptomatic irreversible pulpitis. As part of 37 studies, 3169 subjects/patients were evaluated for missed IAN blocks. The study included 2450 asymptomatic subjects and 719 emergency patients presenting with symptomatic irreversible pulpitis. Each subject or patient received either a 1- or 2-cartridge volume of 2% lidocaine with 1:100,000 epinephrine. A missed block was defined as no lip numbness at 15-20 minutes after the IAN block. The effect of anesthetic volume on the incidence of missed blocks was assessed by using mixed models logistic regression with individual studies as a random effect. The incidence of missed blocks for asymptomatic subjects was 6.3% for the 1-cartridge volume and 3.8% for the 2-cartridge volume. For patients presenting with irreversible pulpitis, the incidence of missed blocks was 7.7% for the 1-cartridge volume and 2.3% for the 2-cartridge volume. In both asymptomatic subjects and patients with irreversible pulpitis, the 2-cartridge volume was significantly (P = .0395) better than the 1-cartridge volume. There were no significant effects for pulpal diagnosis (P = .7523) or the pulpal diagnosis and anesthetic volume interaction (P = .3973). Concerning missed IAN blocks, we concluded that administration of a 2-cartridge volume was significantly better (P = .0395) than a 1-cartridge volume in both asymptomatic subjects and emergency patients presenting with irreversible pulpitis.

    Although coronary artery disease (CAD) is the leading cause of death in type 2 diabetic patients, it is frequently asymptomatic. Myocardial perfusion imaging (MPI) is reported to show ischemia in a significant number of asymptomatic diabetic patients. We studied the prevalence and severity of myocardial perfusion defects in asymptomatic diabetic patients and its clinical impact. One hundred thirty consecutive asymptomatic patients, aged 35-65 years with type 2 diabetes mellitus and with no history of CAD and no cardiac symptoms were recruited in the study. Echocardiography, electrocardiography (ECG), routine laboratory tests and exercise treadmill test (ETT) were performed and patients with weakly positive or negative ETT underwent Dipyridamole MPI. Patients with positive ETT were referred to coronary angiography. Patients were followed for at least 17 months (mean 21.7 months) and any cardiac event was recorded. We studied 81 female and 49 male patients with mean age of 51.8 years. Negative, weakly positive and positive ETT result was noted in 74.3%, 15% and 10.7% respectively. 75% of patients with positive ETT had coronary artery disease in angiography. Gated myocardial perfusion SPECT was done in 106 patients. MPI showed reversible defect in 26.9% of the patients with a mean summed stress score of 3.3±1.8. Follow up completed in 112 patients and only one patient with abnormal MPI underwent coronary angiography followed by PTCA. No cardiac death, MI, UA or hospital admission occurred among our patients during follow up (17-26 months). Mean stress end diastolic volume (EDV) was significantly higher in patients with reversible defect compared to patients without reversible defect based on MPI findings (62.0±31.6 Vs 48.5±18.4 ml, P=0.04). Blood glucose and HbA1c were significantly higher in patients with ischemia compared to patients without ischemia (P<0.05). Meanwhile the ratio of TG to HDL was 6.06±3.2 in ischemic patients compared to 4.8±2.3 in normal

    • BACKGROUND: The prevalence of carotid artery stenosis (CAS in the  eneral population is not high enough to justify screening programs. This study was done to determine the prevalence of asymptomatic carotid artery stenosis (ACAS among patients with severe peripheral vascular disease (PVD.
    • METHODS: Between March 2005 and February 2006, 54 consecutive  atients with severe PVD admitted at a vascular surgery unit and underwent carotid duplex scanning in a prospective study. A  uestionnaire was used to collect data concerning known risk factors. Significant CAS was defined as a stenosis of 70% or greater.
    • RESULTS: The mean age was 62.5 years (51-72. Out of 54 patients, 2 (3.7% had an occluded internal carotid artery. Significant CAS was found in 9 (16.7% and its presence was correlated with diabetes, hypertension, hypercholesterolemia, hypertriglyceridemia, coronary artery disease, severity of symptoms, ankle-brachial index, and carotid bruit. On multivariate analysis, only hypercholesterolemia and carotid bruit seemed to have independent influence.
    • CONCLUSION: The prevalence of significant ACAS is higher among  atients with severe PVD. This patient population may indicate a  uitable subgroup for screening of ACAS, especially when hypercholesterolemia and carotid bruit are present.

  11. AIDS Cholangiopathy in an Asymptomatic, Previously Undiagnosed Late-Stage HIV-Positive Patient from Kenya

    Yiming Gao

    2011-01-01

    Full Text Available AIDS-associated cholangiopathy is a form of biliary tract inflammation with stricture formation seen in AIDS patients who are severely immunosuppressed. It is no longer common in countries in which HAART therapy is widely employed but is still seen in underdeveloped countries. The majority of patients are symptomatic at the time of presentation. Herein, we describe a seventy-four-year-old woman who presented with unilateral leg swelling after a prolonged airplane flight. She was otherwise entirely asymptomatic. Routine laboratory testing was notable for a hypochromic microcytic anemia, slight leukopenia, and mild hypoalbuminemia. Liver enzymes were all elevated. Deep venous thrombosis was confirmed, and a CT scan of the chest disclosed no pulmonary emboli. However, the visualized portion of the abdomen showed dilatation of the common bile and pancreatic ducts. This was confirmed on ultrasonography and MRCP, and no obstructive lesions were noted. An ERCP revealed a dilated common bile duct without filling defects or strictures. A balloon occlusion cholangiogram showed strictures and beading of the intrahepatic ducts. Shortly thereafter, serology for HIV returned positive along with a depressed CD4 cell count, and the patient was diagnosed with AIDS-associated cholangiography.

  12. Similar Neutrophil-Driven Inflammatory and Antibacterial Responses in Elderly Patients with Symptomatic and Asymptomatic Bacteriuria.

    Yu, Yanbao; Zielinski, Martin D; Rolfe, Melanie A; Kuntz, Melissa M; Nelson, Heidi; Nelson, Karen E; Pieper, Rembert

    2015-10-01

    Differential diagnosis of asymptomatic bacteriuria (ASB) and urinary tract infection (UTI) is based on the presence of diverse symptoms, including fever (≥38.5°C), rigors, malaise, lethargy, flank pain, hematuria, suprapubic discomfort, dysuria, and urgent or frequent urination. There is consensus in the medical community that ASB warrants antibiotic treatment only for patients undergoing urological procedures that lead to mucosal bleeding, catheterized individuals whose ASB persists for more than 48 h after catheter removal, and pregnant women. Pyuria is associated with UTI and implicates host immune responses via release of antibacterial effectors and phagocytosis of pathogens by neutrophils. Such responses are not sufficiently described for ASB. Metaproteomic methods were used here to identify the pathogens and evaluate molecular evidence of distinct immune responses in cases of ASB compared to UTI in elderly patients who were hospitalized upon injury. Neutrophil-driven inflammatory responses to invading bacteria were not discernible in most patients diagnosed with ASB compared to those with UTI. In contrast, proteomic urine analysis for trauma patients with no evidence of bacteriuria, including those who suffered mucosal injuries via urethral catheterization, rarely showed evidence of neutrophil infiltration. The same enzymes contributing to the synthesis of leukotrienes LTB4 and LTC4, mediators of inflammation and pain, were found in the UTI and ASB cohorts. These data support the notion that the pathways mediating inflammation and pain in most elderly patients with ASB are not quantitatively different from those seen in most elderly patients with UTI and warrant larger clinical studies to assess whether a common antibiotic treatment strategy for elderly ASB and UTI patients is justified.

    Gu, Yan-Hong; Kodama, Hiroko; Kato, Tadaaki

    2012-10-01

    Menkes disease (MNK) is an X-linked recessive disorder. Incidence of live-born infants with MNK is 2.8 per million live births in Japan. The aim of this study was to observe congenital malformations (CMs) in MNK patients. Subjects comprised 35 Japanese male patients with classical MNK who received copper histidine treatment. Patient clinical data were obtained anonymously from medical records or medical record summaries by pediatrician's retrospective review through a survey. We observed 21 different CMs in 14 patients. Eight of these had a single CM, while six had multiple CMs. The most frequent CM was higher arched palate with other CMs found in five patients. There was no relationship between CMs and mutations in the ATP7A gene. Using Mann-Whitney U tests, age at death was also significantly lower in MNK patients with CMs (Pheart disease, and one with microphallus. Copyright © 2012 The Japanese Society of Child Neurology.

    OBJECTIVE Inappropriate treatment of asymptomatic bacteriuria (ASB) in the hospital setting is common. We sought to evaluate the treatment rate of ASB at the 3 hospitals and assess the impact of a hospitalist-focused improvement intervention. DESIGN Prospective, interventional trial. SETTING Two community hospitals and a tertiary-care academic center. PATIENTS Adult patients with a positive urine culture admitted to hospitalist services were included in this study. Exclusions included pregnancy, intensive care unit admission, history of a major urinary procedure, and actively being treated for a urinary tract infection (UTI) at the time of admission or >48 hours prior to urine collection. INTERVENTIONS An educational intervention using a pocket card was implemented at all sites followed by a pharmacist-based intervention at the academic center. Medical records of the first 50 eligible patients at each site were reviewed at baseline and after each intervention for signs and symptoms of UTI, microbiological results, antimicrobials used, and duration of treatment for positive urine cultures. Diagnosis of ASB was determined through adjudication by 2 hospitalists and 2 infectious diseases physicians. RESULTS Treatment rates of ASB decreased (23.5%; P=.001) after the educational intervention. Reductions in treatment rates for ASB differed by site and were greatest in patients without classic signs and symptoms of UTI (34.1%; Ppharmacist-based intervention was most effective at reducing ASB treatment rates in catheterized patients. CONCLUSIONS A hospitalist-focused educational intervention significantly reduced ASB treatment rates. The impact varied across sites and by patient characteristics, suggesting that a tailored approach may be useful. Infect Control Hosp Epidemiol 2016;37:1044-1051.

  15. Genetic and infectious profiles of Japanese multiple sclerosis patients.

    Satoshi Yoshimura

    Full Text Available BACKGROUND: Nationwide surveys conducted in Japan over the past thirty years have revealed a four-fold increase in the estimated number of multiple sclerosis (MS patients, a decrease in the age at onset, and successive increases in patients with conventional MS, which shows an involvement of multiple sites in the central nervous system, including the cerebrum and cerebellum. We aimed to clarify whether genetic and infectious backgrounds correlate to distinct disease phenotypes of MS in Japanese patients. METHODOLOGY/PRINCIPAL FINDINGS: We analyzed HLA-DRB1 and -DPB1 alleles, and IgG antibodies specific for Helicobacter pylori, Chlamydia pneumoniae, varicella zoster virus, and Epstein-Barr virus nuclear antigen (EBNA in 145 MS patients and 367 healthy controls (HCs. Frequencies of DRB1*0405 and DPB1*0301 were significantly higher, and DRB1*0901 and DPB1*0401 significantly lower, in MS patients as compared with HCs. MS patients with DRB1*0405 had a significantly earlier age of onset and lower Progression Index than patients without this allele. The proportion and absolute number of patients with DRB1*0405 successively increased with advancing year of birth. In MS patients without DRB1*0405, the frequency of the DRB1*1501 allele was significantly higher, while the DRB1*0901 allele was significantly lower, compared with HCs. Furthermore, DRB1*0405-negative MS patients were significantly more likely to be positive for EBNA antibodies compared with HCs. CONCLUSIONS: Our study suggests that MS patients harboring DRB1*0405, a genetic risk factor for MS in the Japanese population, have a younger age at onset and a relatively benign disease course, while DRB1*0405-negative MS patients have features similar to Western-type MS in terms of association with Epstein-Barr virus infection and DRB1*1501. The recent increase of MS in young Japanese people may be caused, in part, by an increase in DRB1*0405-positive MS patients.

    Spirituality and gratitude are associated with wellbeing. Few if any studies have examined the role of gratitude in heart failure (HF) patients or whether it is a mechanism through which spirituality may exert its beneficial effects on physical and mental health in this clinical population. This study examined associations bet ween gratitude, spiritual wellbeing, sleep, mood, fatigue, cardiac-specific self-efficacy, and inflammation in 186 men and women with Stage B asymptomatic HF (age 66.5 years ±10). In correlational analysis, gratitude was associated with better sleep (r=-.25, pgratitude also had lower levels of inflammatory biomarkers (r=-.17, pgratitude. We found that gratitude fully mediated the relationship between spiritual wellbeing and sleep quality (z=-2.35, SE=.03, p=.02) and also the relationship between spiritual wellbeing and depressed mood (z=-4.00, SE=.075, pGratitude also partially mediated the relationships between spiritual wellbeing and fatigue (z=-3.85, SE=.18, pgratitude and spiritual wellbeing are related to better mood and sleep, less fatigue, and more self-efficacy, and that gratitude fully or partially mediates the beneficial effects of spiritual wellbeing on these endpoints. Efforts to increase gratitude may be a treatment for improving wellbeing in HF patients' lives and be of potential clinical value.

  17. High frequency of asymptomatic hyperparathyroidism in patients with fibromyalgia: random association or misdiagnosis?

    Juliana Maria de Freitas Trindade Costa

    Full Text Available ABSTRACT Fibromyalgia (FM and hyperparathyroidism may present similar symptoms (musculoskeletal pain, cognitive disorders, insomnia, depression and anxiety, causing diagnostic confusion. Objectives: To determine the frequency of asymptomatic hyperparathyroidism in a sample of patients with FM and to evaluate the association of laboratory abnormalities to clinical symptoms. Methods: Cross-sectional study with 100 women with FM and 57 healthy women (comparison group. Parathyroid hormone (PTH, calcium and albumin levels were accessed, as well as symptoms in the FM group. Results: In FM group, mean serum calcium (9.6 ± 0.98 mg/dL and PTH (57.06 ± 68.98 pg/mL values were considered normal, although PTH levels had been significantly higher than in the comparison group (37.12 ± 19.02 pg/mL; p = 0.001. Hypercalcemic hyperparathyroidism was diagnosed in 6% of patients with FM, and 17% of these women exhibited only high levels of PTH, featuring a normocalcemic hyperparathyroidism, with higher frequencies than those expected for their age. There was no significant association between hyperparathyroidism and FM symptoms, except for epigastric pain, which was more frequent in the group of patients concomitantly with both diseases (p = 0.012. Conclusions: A high frequency of hyperparathyroidism was noted in women with FM versus the general population. Normocalcemic hyperparathyroidism was also more frequent in patients with FM. Longitudinal studies with greater number of patients are needed to assess whether this is an association by chance only, if the increased serum levels of PTH are part of FM pathophysiology, or even if these would not be cases of FM, but of hyperparathyroidism.

  18. Has the time to come leave the "watch-and-wait" strategy in newly diagnosed asymptomatic follicular lymphoma patients?

    Rueda, Antonio; Casanova, María; Redondo, Maximino; Pérez-Ruiz, Elisabeth; Medina-Pérez, Angeles

    2012-05-31

    Historically, the median overall survival for follicular lymphoma (FL) has been considered to be 9-10 years, and no treatment had ever prolonged this time period. Studies conducted more than 20 years ago demonstrated that treating patients with asymptomatic FL at the onset of the disease did not increase their survival, and that almost 20% of these patients did not need any treatment in the first 10 years of follow-up. Based on these facts, most clinical practice guidelines recommend active surveillance policies for patients with asymptomatic FL. The introduction of antiCD-20 monoclonal antibodies, over the last 15 years, has significantly increased the median survival rate to above 14 years. This improvement was achieved before the combination of rituximab and chemotherapy regimens became extensively used in patients with symptomatic disease. Therefore, this increase in survival may currently be more significant. At present, several clinical trials have evaluated low-toxicity therapies that prolong progression-free periods, among which rituximab monotherapy, radioimmunotherapy or the combination of rituximab with bendamustine are the most relevant. Unfortunately, these clinical trials have included only patients with symptomatic FL. The results of a recently reported clinical trial show that treatment with single-agent rituximab prolongs progression-free survival rates, time to new treatment and the quality of life of asymptomatic patients, as compared with the active surveillance strategy.

    Full Text Available Abstract Background Historically, the median overall survival for follicular lymphoma (FL has been considered to be 9-10 years, and no treatment had ever prolonged this time period. Studies conducted more than 20 years ago demonstrated that treating patients with asymptomatic FL at the onset of the disease did not increase their survival, and that almost 20% of these patients did not need any treatment in the first 10 years of follow-up. Based on these facts, most clinical practice guidelines recommend active surveillance policies for patients with asymptomatic FL. Discussion The introduction of antiCD-20 monoclonal antibodies, over the last 15 years, has significantly increased the median survival rate to above 14 years. This improvement was achieved before the combination of rituximab and chemotherapy regimens became extensively used in patients with symptomatic disease. Therefore, this increase in survival may currently be more significant. At present, several clinical trials have evaluated low-toxicity therapies that prolong progression-free periods, among which rituximab monotherapy, radioimmunotherapy or the combination of rituximab with bendamustine are the most relevant. Unfortunately, these clinical trials have included only patients with symptomatic FL. The results of a recently reported clinical trial show that treatment with single-agent rituximab prolongs progression-free survival rates, time to new treatment and the quality of life of asymptomatic patients, as compared with the active surveillance strategy. Longer follow-up of these results and data regarding overall survival are awaited before this treatment can be recommended as the standard initial therapy.

  1. Antihypertensive treatment with β-blockade in patients with asymptomatic aortic stenosis and association with cardiovascular events

    Bang, Casper N.; Greve, Anders M.; Rossebø, Anne B.

    2017-01-01

    Background--Patients with aortic stenosis (AS) often have concomitant hypertension. Antihypertensive treatment with a β-blocker (Bbl) is frequently avoided because of fear of depression of left ventricular function. However, it remains unclear whether antihypertensive treatment with a Bbl...... is associated with increased risk of cardiovascular events in patients with asymptomatic mild to moderate AS. Methods and Results--We did a post hoc analysis of 1873 asymptomatic patients with mild to moderate AS and preserved left ventricular ejection fraction in the SEAS (Simvastatin and Ezetimibe in Aortic...... Stenosis) study. Propensity-matched Cox regression and competing risk analyses were used to assess risk ratios for all-cause mortality, sudden cardiac death, and cardiovascular death. A total of 932 (50%) patients received Bbl at baseline. During a median follow-up of 4.3±0.9 years, 545 underwent aortic...

  2. Chlamydia trachomatis and Neisseria gonorrhoeae in asymptomatic family planning patients in rural New Mexico.

    Bell, T A; Ebenezer, M R

    1989-01-01

    We tested 98 asymptomatic women seen in state-funded contraception clinics in rural New Mexico. A fluorescein-conjugated monoclonal antibody stain revealed Chlamydia trachomatis infection in 25% of asymptomatic unmarried women and 3% of married women (P = .03). Neisseria gonorrhoeae was detected in only one woman. As in urban clinics providing contraception, the prevalence of gonorrhea is rare in rural New Mexico, but chlamydial infections are common in young unmarried women.

    Although of interest, few data exist on the clinical characteristics of Japanese patients with an extremely high triglyceride level (≥ 1000 mg/dL). We assessed the clinical characteristics of Japanese patients with an extremely high triglyceride level. We investigated the presence of coronary artery disease, history of pancreatitis, the presence of fatty liver, and the potential causes of elevated triglyceride in Japanese subjects with an extremely high level of fasting triglyceride (≥ 1000 mg/dL) among 70,368 subjects whose serum triglyceride was measured for any reason at Kanazawa University Hospital from April 2004 to March 2014. We identified 215 (0.31%) subjects (mean age, 46 years; male, 170, mean body mass index, 25 kg/m(2)) with severe hypertriglyceridemia. Among them, 4 (1.9%) subjects were classified as type I, 97 (45.1%) subjects were type IV, and 114 (53.0%) subjects were type V hyperlipidemia, according to Fredrickson's classification. Among 215 subjects, 116 subjects (54.0%) drank alcohol, 58 (27.0%) showed heavy intake (≥ 60 g/d), and 64 (29.8%) subjects had diabetes. In total, 59 (27.4%) subjects had transient severe hypertriglyceridemia caused by corticosteroids (N = 19), antidepressant (N = 18), l-asparaginase and steroids for acute lymphoid leukemia (N = 15), hormone replacement therapy for breast cancer (N = 9), β-blocker (N = 5), hypothyroidism (N = 4), pregnancy (N = 4), and panhypopituitarism (N = 2). As many as 119 (55.3%) subjects exhibited fatty liver. Moreover, 12 (5.6%) and 17 (7.9%) subjects had a history of pancreatitis and coronary artery disease, respectively. A variety of situations can cause severe hypertriglyceridemia. We suggest that potential secondary causes should be carefully assessed for such patients. Copyright © 2015 National Lipid Association.

  4. Characteristics of the Motor Units during Sternocleidomastoid Isometric Flexion among Patients with Mechanical Neck Disorder and Asymptomatic Individuals.

    Chia-Chi Yang

    Full Text Available Mechanical neck disorder is a widespread and non-neurological musculoskeletal condition resulting from modern lifestyles. Presently, the fundamental electrophysiological properties of the motor units of the sternocleidomastoid muscles and the characteristics of the short-term synchronization of the motor unit in patients with neck pain are ambiguous. This study therefore aims to clarify the fundamental electrophysiological properties of the motor units of the sternocleidomastoid muscles in patients with mechanical neck disorder and in asymptomatic individuals. We further investigated whether alterations in the degree of motor unit short-term synchronization occur. The surface electrophysiological signals of the bilateral sternal heads of the sternocleidomastoid muscles of twelve patients with mechanical neck disorder and asymptomatic individuals were detected at 25% of the maximum voluntary contraction during cervical isometric flexion and then decomposed into individual motor unit action potential trains. We found that the patients with mechanical neck disorder showed significantly higher initial and mean firing rates of the sternocleidomastoid muscles and displayed substantially lower motor unit short-term synchronization values compared with the asymptomatic subjects. Consequently, these convincing findings support the assertion that patients with mechanical neck disorder display altered neuromuscular control strategies, such as the reinforcement of motor unit recruitment firing rates in the sternocleidomastoid muscles. The motor units of these patients also revealed neural recruitment strategies with relatively poor efficiency when executing the required motor tasks.

    1998-01-01

    We describe the MRI findings in three Japanese patients with spinocerebellar ataxia type 6 (SCA6) in which a polymorphic CAG repeat was identified in the gene encoding the α 1A voltage-dependent P/Q-type Ca 2+ channel subunit (CACNL1A4). All showed slowly progressive cerebellar ataxia and mild pyramidal signs. Neuroradiologically, they had moderate cerebellar atrophy, most prominently in the superior vermis, whereas the brain stem appeared to be spared. No abnormal signal intensity was identified. (orig.)

  7. The measurement of 99mTc-DTPA pulmonary clearance in normals, asymptomatic smokers and diabetic patients

    Kim, In Ju; Kim, Seong Jang; Kim, Yong Ki; Kim, Yun Seong; Lee, Min Ki; Park, Soon Kew

    1998-01-01

    We measured pulmonary epithelial permeability by 99m Tc-DTPA radioaerosol clearance in patients with diabetes and correlated with the presence of microangiopathy to understand the pathophysiology of pulmonary microangiopathy and evaluate 99m Tc-DTPA radioaerosol clearance as a diagnostic test to assess pulmonary microangiopathy. We performed 99m Tc-DTPA radioaerosol scan in 10 normal subjects, 10 asymptomatic smokers, 20 diabetic patients without history of smoking (10 with microangiopathy, 10 without microangiopathy). 99m Tc-DTPA clearance half-time (T 1/2 ) was calculated, then compared with the result of chest radiography and pulmonary function test. Chest radiography and pulmonary function test were normal in all subjects. There were no significant difference of clinical or laboratory characteristics between these groups except age. The diabetic patients with microangiophaty were significantly older (p 1/2 of normal subjects and asymptomatic smokers were significantly different (65.2±23.7 min vs 39.6±9.8 min, p 1/2 was 90.5±46.5 min and significantly delayed when compared with those of normals and asymptomatic smokers (p 1/2 of diabetic patients without microangiopathy, 70.0±12.7 min, was not significantly different from those of normals or asymptomatic smokers (p>0.05). No significant correlation was found between the T 1/2 and spirometric parameters including DLco, FVC, FEV 1 , FEV 1 /FVC (%) and FEF 25-75% in all subjects, and between the T 1/2 and duration of diabetes in diabetic patients. Eventhough the influence of age can't be excluded, delayed 99m Tc-DTPA clearance half-time (T 1/2 ) in diabetic patients with microangiopathy indicates decreased pulmonary capillary permeability as one of the pathophysiologic results of pulmonary microangiopaththy. Further studies are needed in larger number of age matched control and diabetic patients to evaluate the diagnostic efficacy

  8. Occurrence of maxillary sinus abnormalities detected by cone beam CT in asymptomatic patients

    Rege Inara Carneiro

    2012-08-01

    Full Text Available Abstract Background Although cone beam computed tomography (CBCT images of the maxillofacial region allow the inspection of the entire volume of the maxillary sinus (MS, identifying anatomic variations and abnormalities in the image volume, this is frequently neglected by oral radiologists when interpreting images of areas at a distance from the dentoalveolar region, such as the full anatomical aspect of the MS. The aim of this study was to investigate maxillary sinus abnormalities in asymptomatic patients by using CBCT. Methods 1113 CBCT were evaluated by two examiners and identification of abnormalities, the presence of periapical lesions and proximity to the lower sinus wall were recorded. Data were analyzed using descriptive statistics, chi-square tests and Kappa statistics. Results Abnormalities were diagnosed in 68.2% of cases (kappa = 0.83. There was a significant difference between genders (p Conclusions Abnormalities in maxillary sinus emphasizes how important it is for the dentomaxillofacial radiologist to undertake an interpretation of the whole volume of CBCT images.

  9. Electrophysiology testing and catheter ablation are helpful when evaluating asymptomatic patients with Wolff-Parkinson-White pattern: the con perspective.

    Skanes, Allan C; Obeyesekere, Manoj; Klein, George J

    2015-09-01

    The association between asymptomatic Wolff-Parkinson-White (WPW) syndrome and sudden cardiac death (SCD) has been well documented. The inherent properties of the accessory pathway determine the risk of SCD in WPW, and catheter ablation essentially eliminates this risk. An approach to WPW syndrome is needed that incorporates the patient's individualized considerations into the decision making. Patients must understand that there is a trade-off of a small immediate risk of an invasive approach for elimination of a small lifetime risk of the natural history of asymptomatic WPW. Clinicians can minimize the invasive risk by only performing ablation for patients with at-risk pathways. Copyright © 2015 Elsevier Inc. All rights reserved.

  10. Detection of exercise induced ischemia in the asymptomatic recent post myocardial infarction patient: comparison of stress electrocardiography and radionuclide angiography

    Jengo, J.A.; Brizendine, M.; Dykstra, L.; Sweet, J.; Bruno, M.; Garcia, A.

    1982-01-01

    The purpose of this study was to compare the techniques of low level stress electrocardiography and radionuclide angiographic wall motion analysis for the detection of new areas of myocardial ischemia in the asymptomatic recent post-myocardial infarction patient. The protocol consisted of obtaining a resting, RAO upright first pass radionuclide angiocardiogram using 15 mCi of 99m technetium-DTPA. The study suggests that assessment of segmental wall motion during low level stress can detect areas of myocardium at high risk either intermixed with or in addition to recently infarcted areas in the asymptomatic post-infarction patient, which are not detected by ECG. This high risk subset of patients can then be observed or treated in a more vigorous manner. This technique allows for not only the identification of additional areas of myocardium at jeopardy but also provides information regarding the severity of ischemic dysfunction, an important prognostic and therapeutic factor

    Abstract Objective. To assess the frequency of malalignment in the 1st, 2nd and 3rd tarso-metatarsal joints (Lisfranc joint) in cadaveric specimen and asymptomatic individuals utilizing oblique axial MR images.Design and patients. Four fresh frozen cadaveric feet were dissected in the oblique axial plane at 5 mm slice thickness. Thirty MR studies in 29 patients who had no history of pain, trauma or surgery at the tarso-metatarsal area were included in our study. The 1st to 3rd tarso-metatarsal joints were evaluated on the MR studies and cadaveric slices by two musculoskeletal radiologists for (1) the presence of a medial and/or lateral step-off and (2) articular surface divergence.Results. In the cadaveric dissections there were lateral step-offs in the 1st (n=3) and in the 2nd ray (n=3) respectively. No joint incongruity was evidenced. The MR studies in the patients population depicted 28 step-offs (9 medial, 19 lateral) in the 1st ray, 16 (2 medial, 14 lateral) in the 2nd ray and two in the 3rd ray. Joint incongruity was present in the 2nd ray (n=6) and in the 3rd ray (n=12). All the above findings were limited to a few images.Conclusions. Isolated joint malalignment with otherwise normal findings (no ligamentous injury, no fracture and no bone marrow edema) might reflect normal anatomic features at the tarso-metatarsal joints and must be interpreted carefully.

    2014-06-01

    The objective of this work is to compare the effectiveness of hormonal treatment (luteinizing hormone-releasing hormone agonists and/or antiandrogens) as an early or as a deferred intervention for patients with locally advanced prostate cancer (LAPC) and/or asymptomatic metastasis. Systematic review of trials published in 1950-2007. Sources included MEDLINE and bibliographies of retrieved articles. Eligible trials included adults with a history of LAPC who are not suitable for curative local treatment of prostate cancer. We retrieved 22 articles for detailed review, of which 8 met inclusion criteria. The Veterans Administration Cooperative Urological Research Group suggested that delaying hormonal therapy did not compromise overall survival and that many of the patients died of causes other than prostate cancer. In European Organisation for Research and Treatment of Cancer (EORTC) 30846 trial, the median survival for delayed endocrine treatment was 6.1 year, and for immediate treatment 7.6 year, the HR for survival on delayed versus immediate treatment was 1.23 (95 % CI 0.88-1.71), indicating a 23 % nonsignificant trend in favour of early treatment. In EORTC 30891, the immediate androgen deprivation resulted in a modest but statistically significant increase in overall survival. The protocol SAKK 08/88 showed the lack of any major advantage of immediate compared with deferred hormonal treatment regarding quality of life or overall survival. The early intervention with hormonal treatment for patients with LAPC provides important reductions in all-cause mortality, prostate cancer-specific mortality, overall progression, and distant progression compared with deferring their use until standard care has failed to halt the disease.

    This study was conducted to compare diffusion tensor MR imaging (DTI) metrics of the cervical spinal cord in asymptomatic human immunodeficiency virus (HIV)-positive patients with those measured in healthy volunteers, and to assess whether DTI is a valuable diagnostic tool in the early detection of HIV-associated myelopathy (HIVM). MR imaging of the cervical spinal cord was performed in 20 asymptomatic HIV-positive patients and in 20 healthy volunteers on a 3-T MR scanner. Average fractional anisotropy (FA), mean diffusivity (MD), and major (E1) and minor (E2, E3) eigenvalues were calculated within regions of interest (ROIs) at the C2/3 level (central and bilateral anterior, lateral and posterior white matter). Statistical analysis showed significant differences with regard to mean E3 values between patients and controls (p = 0.045; mixed-model analysis of variance (ANOVA) test). Mean FA was lower, and mean MD, mean E1, and mean E2 were higher in each measured ROI in patients compared to controls, but these differences were not statistically significant. Asymptomatic HIV-positive patients demonstrate only subtle changes in DTI metrics measured in the cervical spinal cord compared to healthy volunteers that currently do not support using DTI as a diagnostic tool for the early detection of HIVM.

    2006-01-01

    To compare the prevalence of asymptomatic oral candidal carriage in healthy volunteers with human immunodeficiency virus (HIV)-positive patients in China, as well as to investigate the relationship between CD4+ lymphocyte count and oral candidal colonization or oral candidiasis. Oral candidal carriage and oral candidiasis were investigated in 101 patients with HIV-infection seen at Youan Hospital, Beijing, China. Two hundred and seventeen healthy volunteers were involved as a control. Culture from saliva was used to test for the presence of oral Candida. CD4+ lymphocyte count was measured by flow cytometry. All data were analyzed statistically by SAS. Asymptomatic oral candidal carriage rate (28.6%) in HIV-positive group was similar to that in the healthy group (18.0%; P = 0.07). No significant difference in CD4+ lymphocyte count was found between oral Candida carriers and non-carriers among HIV-positive subjects (P = 0.89). However, the frequency of oral candidiasis increased with the decrease in CD4+ lymphocyte count (P < 0.0001), and pseudomembranous candidiasis was predominant in HIV-positive patients with CD4+ <200 cells microl(-1) (66.7%). In HIV-positive subjects, asymptomatic oral candidal colonization is not related to CD4+ lymphocyte count of blood, and the carriage rate is similar to that in the healthy population. Oral candidiasis is more likely to be observed in HIV-positive patients who have a low CD4+ lymphocyte count.

  15. Isolated asymptomatic masseter muscle metastasis as first sign of metastatic disease in a patient with known melanoma

    Caroline Asirvatham Gjorup

    2016-12-01

    Full Text Available A 65-year-old woman diagnosed with a nodular melanoma on the right shoulder had a PET/CT scan 13 months later demonstrating a FDG-avid mass in the left masseter muscle, which was asymptomatic and not clinically evident. Pathologic analysis confirmed metastasis of melanoma. Further subcutaneous, intramuscular and bone metastases developed and the patient was treated with surgery and immunotherapy. The patient is in complete-remission with no evident metastases seen on PET/CT 2.5 years after treatment with adoptive cell therapy using tumor-infiltrating lymphocytes (TIL therapy. Asymptomatic skeletal muscle metastases identified with PET/CT can have therapeutic and prognostic implications and a PET/CT scan should be performed as a true whole-body scan.

  16. Abnormal lung gallium-67 uptake preceding pulmonary physiologic impairment in an asymptomatic patient with Pneumocystis carinii pneumonia

    Reiss, T.F.; Golden, J.

    1990-01-01

    Pneumocystis carinii pneumonia was suggested by a diffuse, bilateral pulmonary uptake of gallium-67 in an asymptomatic, homosexual male with the antibody to the immunodeficiency virus (HIV) who was undergoing staging evaluation for lymphoma clinically localized to a left inguinal lymph node. Chest radiograph and pulmonary function evaluation, including lung volumes, diffusing capacity and arterial blood gases, were within normal limits. Bronchoalveolar lavage revealed Pneumocystis carinii organisms. In this asymptomatic, HIV-positive patient, active alveolar infection, evidenced by abnormal gallium-67 scanning, predated pulmonary physiologic abnormalities. This observation raises questions concerning the natural history of this disease process and the specificity of physiologic tests for excluding disease. It also has implications for the treatment of neoplasia in the HIV-positive patient population

Due to restrictive transport at the blood–brain barrier, many drugs provide poor control of metastases in the brain. The aim of this study was to compare erlotinib with pemetrexed as second-/third-line treatment in patients with lung adenocarcinoma with asymptomatic brain metastases.Methods: From January 2012 to June 2014, all lung adenocarcinoma patients with asymptomatic brain metastases who received treatment with erlotinib or pemetrexed as second-/third-line treatment were retrospectively reviewed. Chi-square and log-rank tests were used to perform statistical analysis.Results: The study enrolled 99 patients, of which 44 were positive for EGFR mutation. Median progression-free survival (PFS in months was not significantly different between the erlotinib- and pemetrexed-treated groups (4.2 vs 3.4 months; 95% confidence interval [CI]: 2.01–6.40 vs 2.80–5.00, respectively; P=0.635. Median PFS was found to be significantly longer in EGFR mutation–positive patients in the erlotinib-treated group (8.0 months; 95% CI 5.85–10.15 compared to the pemetrexed group (3.9 months; 95% CI: 1.25–6.55; P=0.032.

  20. Asymptomatic Primary Hyperparathyroidism

    Silverberg, Shonni J.; Walker, Marcella D.; Bilezikian, John P.

    2014-01-01

    The clinical profile of primary hyperparathyroidism (PHPT) as it is seen in the United States and most Western countries has evolved significantly over the past half century. The introduction of the multichannel serum autoanalyzer in the 1970s led to the recognition of a cohort of individuals with asymptomatic hypercalcemia, in whom evaluation led to the diagnosis of PHPT. The term “asymptomatic primary hyperparathyroidism” was introduced to describe patients who lack obvious signs and symptoms referable to either excess calcium or parathyroid hormone. Although it was expected that asymptomatic patients would eventually develop classical symptoms of PHPT, observational data suggest that most patients do not evolve over time to become overtly symptomatic. In most parts of the world, the asymptomatic phenotype of PHPT has replaced classical PHPT. This report is a selective review of data on asymptomatic PHPT: its demographic features, presentation and natural history, as well as biochemical, skeletal, neuromuscular, psychological, and cardiovascular manifestations. In addition, we will summarize available information on treatment indications and options for those with asymptomatic disease. PMID:23374736

    2008-02-01

    The presence or absence of hypothyroidism was assessed in 152 consecutive Japanese patients with end-stage renal disease on hemodialysis. Eight patients who had undergone treatment for thyroid disease before starting hemodialysis therapy, and 3 patients with amyloidosis due to rheumatoid arthritis were excluded. Of the remaining 141 hemodialysis patients, 14 (9.9%) (9 males and 5 females, aged 69.1 A+/- 8.8 years with a mean duration of hemodialysis of 69 A+/- 51 months) were in a hypothyroid state, defined as a thyroid-stimulating hormone (TSH) level > 5 mU/l. Antithyroid peroxidase antibodies were positive in only 1 of the 14 patients, while antithyroglobulin antibodies were negative in all of these patients. After iodide restriction, the serum TSH level decreased in all the patients from a mean of 16.49 A+/- 22.80 to 4.44 A+/- 3.35 mU/l after 1 month, 4.25 A+/- 2.24 mU/l after 2 months and 3.97 A+/- 2.22 mU/l after 3 months. The 3 months of iodide restriction were also associated with decreases in systolic blood pressure (142 A+/- 19 to 125 A+/- 16 mmHg, p patients on hemodialysis. Retention of excess iodide may be the mechanism responsible for reversible hypothyroidism rather than immunological perturbations. It is, therefore, recommended to attempt iodide restriction before starting l-thyroxine replacement therapy.

    Purpose: To assess the diagnostic value of secretin-stimulated MRCP (SS-MRCP) compared with conventional MRCP in asymptomatic patients with mild elevations of pancreatic enzymes. Materials and methods: Eighty asymptomatic patients with pancreatic hyperenzymemia underwent MR imaging at 1.5 T-device (Signa EXCITE, GE Healthcare). After the acquisition of axial T1w,T2w sequences, and conventional MRCP, SS-MRCP was performed using a single-slice coronal breath-hold, thick-slab, SSFSE T2w sequence, repeated every 30 s up to 15 min following intravenous injection of secretin (Secrelux, Sanochemia). Results: On the basis of the standards of reference, our final diagnoses were: negative findings (n = 23), pancreas divisum (n = 22), mild chronic pancreatitis (n = 14), inflammatory ampullary stenosis (n = 3), juxtapapillary duodenal diverticulum (n = 1), small cystic lesions (<1 cm) (n = 22; 5/22 cases associated with pancreas divisum). The image quality of SS-MRCP was significantly higher than that of conventional MRCP (p < 0.0001). Standards of reference did not differ significantly from of SS-MRCP findings (p = 0.5), while was statistically different from those of conventional MRCP (p < 0.0001). A significant difference was found between conventional MRCP and SS-MRCP findings (p < 0.0001). Conclusion: In asymptomatic patients with non-specific pancreatic hyperenzymemia SS-MRCP may represent the best non-invasive diagnostic technique, since it gives morphological and functional information.

    Full Text Available Background/Aims: Colonoscopy and computed tomography (CT are used primarily to exclude organic diseases in patients with irritable bowel syndrome (IBS, rather than to assess the pathophysiology of IBS. We aimed to evaluate colonic dysmotility and morphology in Japanese patients with IBS.Methods: One hundred eighty-four patients with IBS and 49 asymptomatic controls who underwent colonoscopy in combination with CT colonography or barium enema were retrospectively reviewed between 2008 and 2012. Water-aided colonoscopy was performed without sedation by a single endoscopist. The duration and pattern of colonic movement and cecal intubation time were recorded. To assess colonic morphology, barium enema or CT colonography were performed immediately after colonoscopy.Results: Colonic dysmotility was more frequent in the IBS group (28.8% vs. 2.0% in controls, P<0.001, especially in cases of IBS with diarrhea (IBS-D (IBS with constipation [IBS-C] 28.8% vs. IBS-D 60.0% vs. mixed IBS [IBS-M] 5.1%, P<0.001. Colonic morphological abnormality was more frequent in the IBS group than in the control group (77.7% vs. 24.5%, P<0.001, especially in IBS-M and IBS-C groups (IBS-C 77.5% vs. IBS-D 48.9% vs. IBS-M 100%, P<0.001. Most patients with IBS with colonic dysmotility had experienced stress related to their symptoms. Cecal intubation time was significantly longer in the IBS group than in the control group (12.1±6.9 minutes vs. 4.6±1.9 minutes, P<0.001.Conclusions: Unsedated colonoscopy, combined with radiographic findings, can detect colonic dysmotility and morphological abnormality. Technical difficulties observed during cecal intubation may partially explain the pathophysiology of IBS.

    Digestive disorders represent the most common metformin side effects for type 2 diabetes. The mechanism of these metformin side effects is unclear. The aim of this study was to assess whether asymptomatic chronic gastritis could influence metformin tolerance in patients with type 2 diabetes. Demographic, anthropometric, ultrasound and laboratory data were obtained from 144 metformin naïve patients with diabetes. The diagnosis of chronic gastritis was based on endoscopic and histopathological examination, and H. pylori infection was assessed based on (13) C urea breath test (UBT). All subjects started metformin at 500 mg/day and increasing progressively to 1500 mg/day over 4 weeks. A score of gastrointestinal side effects (abdominal pain, diarrhoea, nausea, vomiting, bloating and anorexia) was assessed each week, and metformin dose was adjusted as appropriate. Based on endoscopy, 64 patients were categorized as non-gastritis subjects and 80 as chronic gastritis subjects. At baseline, there is no statistical difference in gastrointestinal symptoms between two groups. With metformin, the mean scores for gastrointestinal symptoms in the non-gastritis and gastritis subjects were 1·02 ± 1·71 vs. 2·18 ± 2·05 (P = 0·001), 0·20 ± 0·65 vs. 0·50 ± 0·89 (P = 0·022), 0 vs. 0·06 ± 0·24 (P = 0·024) and 1·08 ± 1·03 vs. 1·71 ± 1·66 (P = 0·028). The mean final metformin dose used by gastritis subjects was 706·24 ± 568·90 mg, significantly less than the mean dose used by non-gastritis subjects (1101·56 ± 578·58 mg, P = 0·001). After adjustment for age and sex, the odds ratio (OR) for a final metformin dose of less than 1500 mg/day was found to be 2·76 (95% CI 1·38-5·53, P = 0·004) for chronic gastritis subjects. The OR for a final metformin dose of less than 1000 mg/day was found to be 3·98 (95% CI 1·91-8·27, P = 0·001) for chronic gastritis subjects. Our data suggest that pre-existing non-symptomatic gastritis was associated with metformin

  5. Reasons underlying the consent to endovascular treatment, displayed by patients diagnosed with asymptomatic internal carotid artery stenosis.

    Stanišić, Michał-Goran; Rzepa, Teresa

    2014-08-24

    Endovascular treatment of internal carotid artery stenosis (ICAS) has gained popularity in recent years. Offering CAS, which is a controversial treatment in asymptomatic disease, may provoke patient distrust of the diagnosis and intervention benefit. The aim of this study was to prove that asymptomatic ICAS patients tend to show an emotional attitude to their illness, and therefore their decisions regarding carotid artery stenting are externally motivated and assessed emotionally. This study was conducted by a questionnaire consisting of 18 half-open questions (obtained from 25 consecutive patients) in categories of self-image, attitude to illness, and decision-making regarding CAS. Descriptive analysis was performed. Reaction: "Nothing to worry about - every illness can be cured" evidenced the rational attitude to the disease. Attitude towards oneself after receiving the unexpected information about the disease did not change. Most patients pursued a second opinion before the intervention. Most patients showed internal motivation (78.7%). Rational assessment of the decision on CAS relied on consulting and insights into the disease and the intervention-related risk compared to risk of "doing nothing" In decision-making about CAS by asymptomatic patients, the emotional attitude to disease and negative expectations pertaining to postoperative health lead to an internally-motivated and rationally assessed decision. At least 2 conversations with the patient should be scheduled. The primary purpose of the second visit should be dissipating any doubts and repeating the arguments for the intervention. Patients should be provided with an appropriate amount of information to reduce their fear of neurological complications and mental disturbances. Conversation should be concentrated on life-quality improvement instead of controversies about the intervention.

    An asymptomatic case of severe acute respiratory syndrome (SARS) occurred early in 2004, during a community outbreak of SARS in Guangzhou, China. This was the first time that a case of asymptomatic SARS was noted in an individual with antigenemia and seroconversion. The asymptomatic case patient and the second index case patient with SARS in the 2003-2004 outbreak both worked in the same restaurant, where they served palm civets, which were found to carry SARS-associated coronaviruses. Epidemiological information and laboratory findings suggested that the findings for the patient with asymptomatic infection, together with the findings from previously reported serological analyses of handlers of wild animals and the 4 index case patients from the 2004 community outbreak, reflected a likely intermediate phase of animal-to-human transmission of infection, rather than a case of human-to-human transmission. This intermediate phase may be a critical stage for virus evolution and disease prevention.

    Even high-normal albuminuria is reportedly associated with cardiovascular events. We determined the urine albumin creatinine ratio (UACR) in spot urine samples and analyzed the UACR distribution and the prevalence of high-normal levels. The UACR was determined using immunoturbidimetry in 332 untreated asymptomatic non-diabetic Japanese patients with hypertension and in 69 control subjects. The microalbuminuria and macroalbuminuria levels were defined as a UCAR ≥30 and creatinine and a UCAR ≥300 µg/mg·creatinine, respectively. The distribution patterns showed a highly skewed distribution for the lower levels, and a common logarithmic transformation produced a close fit to a Gaussian distribution with median, 25th and 75th percentile values of 22.6, 13.5 and 48.2 µg/mg·creatinine, respectively. When a high-normal UACR was set at >20 to creatinine, 19.9% (66/332) of the hypertensive patients exhibited a high-normal UACR. Microalbuminuria and macroalbuminuria were observed in 36.1% (120/336) and 2.1% (7/332) of the patients, respectively. UACR was significantly correlated with the systolic and diastolic blood pressures and the pulse pressure. A stepwise multivariate analysis revealed that these pressures as well as age were independent factors that increased UACR. The UACR distribution exhibited a highly skewed pattern, with approximately 60% of untreated, non-diabetic hypertensive patients exhibiting a high-normal or larger UACR. Both hypertension and age are independent risk factors that increase the UACR. The present study indicated that a considerable percentage of patients require anti-hypertensive drugs with antiproteinuric effects at the start of treatment.

    Finding agranulocytosis (AG) at an early stage is important to improve outcome, but periodic granulocyte count monitoring is not generally recommended for patients with Graves' disease, because AG develops suddenly. At the Kuma Hospital, Graves' patients under antithyroid drug (ATD) treatment in an outpatient clinic have a granulocyte count examination during each visit, and if it is Graves' disease were 131 I-radioisotope therapy (19 patients), thyroidectomy (2 patients), inorganic iodine (1 patient), or another ATD (1 patient). Among the 33 GP patients, 31 (94%), including 20 asymptomatic cases, were discovered during periodic granulocyte count monitoring. Most of them stopped ATD, and other treatments for Graves' disease were selected. Periodic monitoring of granulocyte counts is useful for identifying AG and GP patients with no or minimum infection symptoms.

    Full Text Available Background and purposeAsymptomatic carotid artery stenosis can lead to not only stroke but also cognition impairment. Although it has been proven that carotid artery stenting (CAS can reduce the risk of future strokes, the effect of CAS on cognition is conflicting. In recent years, pulsed arterial spin labeling (pASL MRI and resting-state functional MRI (R-fMRI have been employed in cognitive impairment studies. For the present study, cognition is evaluated in severe asymptomatic carotid artery stenosis patients undergoing CAS, and the mechanisms underlying the cognitive change are explored by pASL MRI and R-fMRI.Materials and methodsWe prospectively enrolled 24 asymptomatic, severe (≥70%, unilateral internal carotid artery stenosis patients, who were expecting the intervention of CAS. Cognition assessment (including the Montreal Cognitive Assessment Beijing Version, the Minimum Mental State Examination, the Digit Symbol Test, the Rey Auditory Verbal Learning Test, and the Verbal Memory Test and an integrated MRI program (pASL MRI, and R-fMRI were administered 7 days before and 3 months after CAS.Results16 subjects completed the follow-up study. After stenting, significant improvement in the scores of the MMSE, the Verbal Memory test, and the delayed recall was found. No significant difference was found in the scores of the Montreal Cognitive Assessment Beijing Version, the Digit Symbol Test, and the immediate recall. After CAS treatment, asymptomatic carotid artery stenosis patients showed increased perfusion in the left frontal gyrus, increased amplitude of low-frequency fluctuation (ALFF in the right precentral gyrus, and increased connectivity to the posterior cingulate cortex (PCC in the right supra frontal gyrus. However, no significant correlations were found between these imaging changes and cognition assessments.ConclusionSuccessful CAS can partly improve cognition in asymptomatic carotid artery stenosis patients. The cognition

    This study sought to determine the anesthetic efficacy of 4% articaine with 1:100,000 epinephrine in patients with symptomatic and asymptomatic irreversible pulpitis in mandibular posterior teeth and if individual patient factors, pulpal disease characteristics, and previous medication are correlated to local anesthetic success. A second objective was to determine the specificity and sensibility of a cold test for prediction of anesthetic success prior to endodontic treatment. Seventy patients diagnosed with irreversible pulpitis in mandibular posterior teeth received 1.6 mL of 4% articaine with 1:100,000 epinephrine for an inferior alveolar nerve block (IANB) using a metal guide. The anesthetic solution was injected with a computer-preprogrammed delivery system for local anesthesia. Endodontic access was begun 15 minutes after solution deposition; later, patients rated their discomfort using the visual analog scale (VAS). The success rate for the IA NB using articaine was 64.2% in patients with symptomatic irreversible pulpitis and 86.9% in patients with asymptomatic irreversible pulpitis. Cold test prior to root canal treatment had a specificity and sensibility of 12.5% and 87.1%, respectively. The anesthetic efficacy of articaine in irreversible pulpitis is moderately acceptable, and anesthetic success increases when the patient has been premedicated with NSAIDs. The cold test appears to be a favorable indicator for predicting anesthetic success.

    Electrocardiograms are routinely obtained in clinical follow-up of patients with asymptomatic aortic stenosis (AS). The association with aortic valve, left ventricular (LV) response to long-term pressure load, and clinical covariates is unclear and the clinical value is thus uncertain. Data from...... clinical examination, electrocardiogram, and echocardiogram in 1,563 patients in the Simvastatin and Ezetimibe in Aortic Stenosis (SEAS) study were used. Electrocardiograms were Minnesota coded for arrhythmias and atrioventricular and intraventricular blocks; LV hypertrophy was assessed by Sokolow...

    Urinary tract infection in pregnancy leads to poor pregnancy outcome. Diagnosis and treatment of asymptomatic bacteriuria markedly improves pregnancy outcome as well as reduce the incidence of acute pyelonephritis. To determine the prevalence and bacteriology of asymptomatic bacteriuria among Antenatal patients in our centre, and to know if routine screening will be justifiable. This was a prospective study carried out between April and August 2008. Sample size was statistically determined. Women who consented were interviewed and mid stream urine samples were collected and processed in the microbiology laboratory, using standard microbiological methods. Out of 357 women studied, 65(18.21%) had significant bacteriuria. Escherichia coli was the commonest isolate (25.6%), while proteus mirabilis was the least frequent isolate (3.66%). Women in third trimester had the highest prevalence (25.68%) while those in the first trimester had the least (15.79%). Women that had only primary education had the highest prevalence (27.50%) while those that had tertiary education had the least prevalence (21.10%). The prevalence of significant asymptomatic bacteriuria among the women studied was high. Screening of all the pregnant women and treatment will reduce the incidence and complications of overt urinary tract infection in pregnancy among these women.

    To clarify the extent of asymptomatic cerebrovascular involvement in systemic lupus erythematosus (SLE). Cerebral magnetic resonance imaging (MRI) findings and ultrasonography findings of 100 patients with SLE lacking present or past clinical neurologic deficits were compared with 66 age-matched volunteers to determine the combined intima-media thickness (IMT) of the common carotid artery, and tests for anti-cardiolipin antibodies (aCL). Thirty-eight patients, but only 2 controls, showed imaging abnormalities. Among 23 SLE patients with cerebrovascular lesions by MRI who underwent single-photon emission computed tomography (SPECT), 14 showed hypoperfusion of the lesion. The IMT value and prevalence of aCL did not differ between the 55 SLE patients tested and controls. SLE disease activity index (SLEDAI) as assessed by a quantitative clinical index was significantly greater in patients with brain lesions than in those without. The prevalence of asymptomatic brain lesions in SLE patients is high, and shows a relationship to disease activity. (author)

    Antiphospholipid antibodies (aPL) can be detected in asymptomatic carriers and infectious patients. The aim was to investigate whether a novel line immunoassay (LIA) differentiates between antiphospholipid syndrome (APS) and asymptomatic aPL+ carriers or patients with infectious diseases (infectious diseases controls (IDC)). Sixty-one patients with APS (56 primary, 22/56 with obstetric events only, and 5 secondary), 146 controls including 24 aPL+ asymptomatic carriers and 73 IDC were tested on a novel hydrophobic solid phase coated with cardiolipin (CL), phosphatic acid, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, phosphatidylserine, beta2-glycoprotein I (β2GPI), prothrombin, and annexin V. Samples were also tested by anti-CL and anti-β2GPI ELISAs and for lupus anticoagulant activity. Human monoclonal antibodies (humoAbs) against human β2GPI or PL alone were tested on the same LIA substrates in the absence or presence of human serum, purified human β2GPI or after CL-micelle absorption. Comparison of LIA with the aPL-classification assays revealed good agreement for IgG/IgM aß2GPI and aCL. Anti-CL and anti-ß2GPI IgG/IgM reactivity assessed by LIA was significantly higher in patients with APS versus healthy controls and IDCs, as detected by ELISA. IgG binding to CL and ß2GPI in the LIA was significantly lower in aPL+ carriers and Venereal Disease Research Laboratory test (VDRL) + samples than in patients with APS. HumoAb against domain 1 recognized β2GPI bound to the LIA-matrix and in anionic phospholipid (PL) complexes. Absorption with CL micelles abolished the reactivity of a PL-specific humoAb but did not affect the binding of anti-β2GPI humoAbs. The LIA and ELISA have good agreement in detecting aPL in APS, but the LIA differentiates patients with APS from infectious patients and asymptomatic carriers, likely through the exposure of domain 1.

  18. Prognostic importance of silent myocardial ischemia detected by intravenous dipyridamole thallium myocardial imaging in asymptomatic patients with coronary artery disease

    1989-01-01

    One hundred seven asymptomatic patients who underwent intravenous dipyridamole thallium imaging were evaluated to determine prognostic indicators of subsequent cardiac events over an average follow-up period of 14 +/- 10 months. Univariate analysis of 18 clinical, scintigraphic and angiographic variables revealed that a reversible thallium defect, a combined fixed and reversible thallium defect, number of segmental thallium defects and extent of coronary artery disease were significant predictors of subsequent cardiac events. Of the 13 patients who died or had a nonfatal infarction, 12 had a reversible thallium defect. Stepwise logistic regression analysis selected a reversible thallium defect as the only significant predictor of cardiac events. When death or myocardial infarction was the outcome variable, a combined fixed and reversible thallium defect was the only predictor of outcome. In patients without previous myocardial infarction, the cardiac event rate was significantly greater in those with an abnormal versus normal thallium scan (55% versus 12%, p less than 0.001). Thus, intravenous dipyridamole thallium scintigraphy is a useful noninvasive test to risk stratify asymptomatic patients with coronary artery disease. A reversible thallium defect most likely indicates silent myocardial ischemia in a sizable fraction of patients in this clinical subset and is associated with an unfavorable prognosis

    Hyperuricemia (HUA) is the most common disease associated with cardiovascular disease, metabolic syndrome, hypertension, and kidney disease. The objective of the current study was to evaluate the preliminary efficacy, mechanism, and safety of acupuncture on serum uric acid in patients with asymptomatic HUA. A randomized, placebo-controlled trial among 123 patients with asymptomatic HUA was conducted. The acupoints used in the acupuncture group were bilateral Five Shu in Spleen Meridian. Each participant received the intervention once daily for 10 consecutive days. The sham group received the same treatment duration on the same acupoints by the Park Sham Device. All patients underwent measurements of serum or urine creatinine, uric acid, serum lipid profiles, fasting plasma glucose, HbA1c, xanthine oxidase (XOD) and urate-anion exchanger (URAT-1). At the end of the intervention, the individuals in the acupuncture group were found to have significantly less levels of serum uric acid than those in the sham group [(453±65 vs. 528±81) μmol/L, puric acid level, urine pH value and 24-hour urine volume than the sham treatment (puric acid in a Chinese HUA patient population. The mechanism might be associated with the decrease level of enzyme URAT-1. ChiCTR-TRC-13004122. Copyright © 2017 Elsevier B.V. All rights reserved.

    The purpose of this study was to evaluate the prevalence of an abnormal stress myocardial perfusion study in a cohort of truly asymptomatic patients with type 2 diabetes mellitus using myocardial perfusion imaging by means of single photon emission computed tomography (SPECT). Secondly, we determined which clinical characteristics may predict an abnormal stress myocardial perfusion study in this population. A total of 120 asymptomatic patients (mean age 53±10 years) with type 2 diabetes mellitus and one or more risk factors for coronary artery disease were prospectively recruited from an outpatient diabetes clinic. All patients underwent myocardial perfusion imaging by means of adenosine 99m Tc sestamibi SPECT. Images were evaluated for the presence of perfusion abnormalities as well as other nonperfusion abnormalities that may indicate extensive ischaemia, including left ventricular dysfunction (defined as a left ventricular ejection fraction <45%), transient ischaemic dilatation and adenosine-induced ST segment depression. Multivariable analysis was performed using a backward selection strategy to identify potential predictors for an abnormal stress myocardial perfusion study. Finally, all patients were followed up for 12 months to determine the occurrence of cardiovascular events: (1) cardiac death, (2) nonfatal myocardial infarction, (3) unstable angina requiring hospitalization, (4) revascularization, or (5) stroke. Of the 120 patients, 40 (33%) had an abnormal stress study, including myocardial perfusion abnormalities in 30 patients (25%). In 10 patients (8%), indicators of extensive (possibly balanced ischaemia) were observed in the absence of abnormal perfusion. The multivariable analysis identified current smoking, duration of diabetes and the cholesterol/high-density lipoprotein (HDL) ratio as independent predictors of an abnormal stress study. During a follow-up period of 12 months six patients (5%) had a cardiovascular event. The current study revealed

    Full Text Available Introduction and Objectives: Bronchiectasis is a pulmonary manifestation that often occurs in individuals with rheumatoid arthritis (RA. Nevertheless, the prevalence of bronchiectasis in RA patients and predictors of its development/progression remain ill-defined. Our objective was to investigate the prevalence of bronchiectasis in a group of RA patients and examine possible clinical or biochemical risk factors that might contribute to its development. Methods: This was an observational study analyzing 100 RA patients with no pulmonary symptoms selected from King Abdulaziz University Hospital in the Western region of Saudi Arabia from October 2013 to 2014. Demographic, clinical and laboratory information were collected for all patients. Diagnosis was based on the 2010 American College of Rheumatology (ACR/European League Against Rheumatism (EULAR classification system, and disease activity was assessed using the 28-Joint Disease Activity Score Index with C-reactive protein; high-resolution computed tomography chest scans were performed. The prevalence of bronchiectasis was recorded and its association with different risk factors was examined using standard statistical methods. Results: All 100 patients fulfilled the ACR and EULAR classification criteria for RA diagnosis. Their mean age was 51.05 ± 13.5 years, disease duration was 6.19 ± 6.4 years and disease activity index was 4 ± 1.3 (moderate activity. A total of 35 (35% patients developed bronchiectasis. Notably, we observed significant positive associations of bronchiectasis with age, disease duration and male gender (P < 0.001, P = 0.006, P = 0.028, respectively. Conclusions: Asymptomatic bronchiectasis represents a common complication in moderately active RA patients within the Western Region of Saudi Arabia. Furthermore, several predictors of bronchiectasis development were identified, which can contribute to effective risk stratification in RA patients. Further prospective studies are

    To analyse quantitatively and qualitatively asymptomatic hepatic and pancreatic involvement in hereditary haemorrhagic telangiectasia (HHT) using 64-section helical CT. The 64-section helical CT examinations of 19 patients with HHT (8 men, 11 women; mean age, 58.6 years) were quantitatively and qualitatively analysed and compared to those of 19 control subjects who were matched for age and sex. Comparisons were made using univariate analysis. Dilated and tortuous intrahepatic arterial branches was the most discriminating independent variable (P < 0.0001) and had the highest specificity (100%; 19/19; 95%CI: 82%-100%) and accuracy (97%; 37/38; 95%CI: 86%-100%) for the diagnosis of HHT. Heterogeneous enhancement of hepatic parenchyma, intrahepatic telangiectases, hepatic artery to hepatic vein shunting, hepatic artery enlargement (i.e. diameter > 6.5 mm) and portal vein enlargement (i.e. diameter > 13 mm) were other variables that strongly correlated with the presence of HHT. Intrapancreatic telangiectases and arteriovenous malformations were found in 42% and 16% of patients with HHT, respectively. Liver and pancreatic involvement in asymptomatic HHT patients is associated with myriad suggestive findings on 64-section helical CT. It can be anticipated that familiarity with these findings would result in more confident diagnosis of HHT. (orig.)

    The purpose of this study was to evaluate retrospectively the impact of [ 18 F]fluorodeoxyglucose positron emission tomography (FDG-PET) on the detection of recurrent breast cancer based on asymptomatically elevated tumor markers levels. Whole-body FDG-PET was performed in 30 patients with suspected recurrent breast cancer and asymptomatic tumor marker increase but negative or equivocal other imaging modality results. A blood sample was drawn in each case for marker assay (CA 15-3 and CEA) on the same day as the FDG-PET. All of these 30 asymptomatic patients had either CA 15-3>32 U/ml or CEA>5 ng/ml. The final diagnosis of recurrent breast cancer was established by operation/biopsy histopathological findings or clinical follow-up for >1 year by additional morphological imaging techniques. Among the 30 patients, the final diagnosis of recurrent breast cancer was established in 38 sites in 28 patients. FDG-PET accurately detected 35/38 sites in 25/28 patients with recurrence. The diagnostic sensitivity and accuracy of FDG-PET in patients with suspected recurrent breast cancer and asymptomatically elevated tumor markers were 96 and 90%, respectively. FDG-PET is a useful technique for detecting recurrent breast cancer suspected from asymptomatically elevated tumor markers levels and has an important clinical impact on the management of these patients.

    To evaluate the treatment effects, safety and pharmacokinetics of enzalutamide in Japanese patients. This was a post-hoc analysis of the phase 3, double-blind, placebo-controlled PREVAIL trial. Asymptomatic or mildly symptomatic chemotherapy-naïve patients with metastatic castration-resistant prostate cancer progressing on androgen deprivation therapy were randomized one-to-one to 160 mg/day oral enzalutamide or placebo until discontinuation on radiographic progression or skeletal-related event and initiation of subsequent antineoplastic therapy. Coprimary end-points were centrally assessed radiographic progression-free survival and overall survival. Secondary end-points were investigator-assessed radiographic progression-free survival, time to initiation of chemotherapy, time to prostate-specific antigen progression, prostate-specific antigen response (≥50% decline) and time to skeletal-related event. Of 1717 patients, 61 were enrolled in Japan (enzalutamide, n = 28; placebo, n = 33); hazard ratios (95% confidence interval) of 0.30 for centrally assessed radiographic progression-free survival (0.03-2.95), 0.59 for overall survival (0.20-1.8), 0.46 for time to chemotherapy (0.22-0.96) and 0.36 for time to prostate-specific antigen progression (0.17-0.75) showed the treatment benefit of enzalutamide over the placebo. Prostate-specific antigen responses were observed in 60.7% of enzalutamide-treated men versus 21.2% of placebo-treated men. Plasma concentrations of enzalutamide were higher in Japanese patients: the geometric mean ratio of Japanese/non-Japanese patients was 1.126 (90% confidence interval 1.018-1.245) at 13 weeks. Treatment-related adverse events grade ≥3 occurred in 3.6% of enzalutamide- and 6.1% of placebo-treated Japanese patients. Treatment effects and safety in Japanese patients were generally consistent with the overall results from PREVAIL. © 2016 The Authors.

    To explore the relationship between cervical spine and the global spine alignment and to postulate the hypotheses that a lordotic alignment of cervical spine is not the only standard to identify asymptomatic subjects, and the degenerative modification of cervical curves depends primarily on their spinal-pelvic alignment. A cohort of 120 cases of Chinese asymptomatic subjects and a cohort of 121 cases of Chinese cervical spondylotic patients were recruited prospectively from 2011 to 2012. Roussouly Classification was utilized to categorize all subjects and patients according to their thoracic spine, lumbar spine and pelvic alignment. The cervical alignments were evaluated as lordosis, straight, sigmoid or kyphosis. Through the lateral X-ray images of neutral cervical and global spine, a number of parameters were measured and analyzed, including pelvic incidence, pelvic tilt, sacral slope, thoracic kyphosis (TK), lumbar lordosis, global cervical angles (angles between two lines parallel with posterior walls of C2 and C7), practical cervical angles (the addition of different cervical end plate angles from C3 to C7, and inter-vertebral angles from C23 to C67), T1 slope, spinal sacral angles (SSA), Hip to C7/Hip to Sacrum and C0-C2 angle. The percentages of cervical lordosis were 28.3% and 36.4% in asymptomatic and spondylotic group, respectively. The cervical spine alignments correlated with Roussouly types of global spine alignment in both asymptomatic and cervical spondylotic group (P inter-vertebral angle in Roussouly Type 2 at C4-5 and C5-6 levels (P = 0.04 and 0.04, respectively), and in Roussouly Type 3 at C6-7 level (P = 0.01). The SSA showed significant difference between Roussouly Type 2 and 4 in asymptomatic subjects (P = 0.00), and between Type 1 and 3, 1 and 4, 2 and 3, 2 and 4 in cervical spondylotic patients (P = 0.01, 0.02, 0.00 and 0.01, respectively). The T1 slope was significantly different among Roussouly types (P = 0.04) with its largest value in

    In this study, we aimed to identify determinants of the different sex-related stroke risk in subjects with asymptomatic internal carotid artery (ICA) stenosis. In all, 492 women (44.4%) and 617 men (55.6%), with unilateral ⩾ 60% asymptomatic ICA stenosis, were prospectively evaluated with a median follow-up of 37 months (interquartile range, 26 to 43). Vascular risk profile, plaque characteristics, stenosis progression, and common carotid artery intima-media thickness were investigated. Outcome measure was the occurrence of ischemic stroke ipsilateral to ICA stenosis. Myocardial infarction, contralateral stroke and transient ischemic attack were considered as competing events. The incidence rate of ipsilateral stroke over the entire follow-up period was 0.16%: 0.09% (95% confidence interval (CI) 0.05 to 0.15) in women and 0.22% (95% CI 0.17 to 0.29) in men (log-rank test, P<0.001). Stenosis progression significantly influenced the risk of ipsilateral stroke in both men (subhazard ratio, SHR, 8.99) and women (SHR 4.89). Stenosis degree (71% to 90%, SHR 2.35; 91% to 99%, SHR 3.38) and irregular plaque surface (SHR 2.32) were relevant risk factors for ipsilateral stroke only in men. Our findings suggest that characteristics of the stenosis and plaque exert a different effect in modulating vascular risk in the two sexes. Understanding sex differences in cardiovascular disease could help to target sex-specific future therapies.

  8. Imported Asymptomatic Bancroftian Filariasis Discovered from a Plasmodium vivax Infected Patient: A Case Report from Singapore

    Jean-Marc Chavatte

    2017-01-01

    Full Text Available Human lymphatic filariasis is a vector-borne disease mainly caused by the parasitic nematode Wuchereria bancrofti and transmitted worldwide within the tropical and subtropical regions. Singapore was once endemic for bancroftian filariasis but recent reports are scarce and the disease is nearly forgotten. The case report presented here reports the incidental hospital laboratory finding of an asymptomatic microfilaremia in a relapsing Plasmodium vivax imported case during a malaria treatment follow-up appointment. The parasite was identified by microscopy as W. bancrofti and retrospective investigation of the sample collected during malaria onset was found to be also positive. Additional confirmation was obtained by DNA amplification, sequencing, and phylogenetic analysis of the mitochondrial cox1 gene that further related the parasite to W. bancrofti strains from the Indian region. Considering the large proportion of asymptomatic filariasis with microfilaremia, the high number of migrants and travellers arriving from the surrounding endemic countries, and the common presence of local competent mosquito vectors, Singapore remains vulnerable to the introduction, reemergence, and the spread of lymphatic filariasis. This report brings out from the shadow the potential risk of lymphatic filariasis in Singapore and could help to maintain awareness about this parasitic disease and its public health importance.

  9. Criterion and construct validity of the CogState Schizophrenia Battery in Japanese patients with schizophrenia.

    Taisuke Yoshida

    Full Text Available BACKGROUND: The CogState Schizophrenia Battery (CSB, a computerized cognitive battery, covers all the same cognitive domains as the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS Consensus Cognitive Battery but is briefer to conduct. The aim of the present study was to evaluate the criterion and construct validity of the Japanese language version of the CSB (CSB-J in Japanese patients with schizophrenia. METHODOLOGY/PRINCIPAL FINDINGS: Forty Japanese patients with schizophrenia and 40 Japanese healthy controls with matching age, gender, and premorbid intelligence quotient were enrolled. The CSB-J and the Brief Assessment of Cognition in Schizophrenia, Japanese-language version (BACS-J were performed once. The structure of the CSB-J was also evaluated by a factor analysis. Similar to the BACS-J, the CSB-J was sensitive to cognitive impairment in Japanese patients with schizophrenia. Furthermore, there was a significant positive correlation between the CSB-J composite score and the BACS-J composite score. A factor analysis showed a three-factor model consisting of memory, speed, and social cognition factors. CONCLUSIONS/SIGNIFICANCE: This study suggests that the CSB-J is a useful and rapid automatically administered computerized battery for assessing broad cognitive domains in Japanese patients with schizophrenia.

    2013-02-01

    Full Text Available Abstract Background There is no consensus regarding the management of ovarian cancer patients, who have shown complete clinical response (CCR to primary therapy and have rising cancer antigen CA-125 levels but have no symptoms of recurrent disease. The present study aims to determine whether follow-up CA-125 levels can be used to identify the need for imaging studies and secondary cytoreductive surgery (CRS. Methods We identified 410 ovarian cancer patients treated at The University of Texas MD Anderson Cancer Center between 1984 and 2011. These patients had shown CCR to primary therapy. Follow-up was conducted based on the surveillance protocol of the MD Anderson Cancer Center. We used the Cox proportional hazards model and log-rank test to assess the associations between the follow-up CA-125 levels and secondary CRS and survival duration. Results The CA-125 level of 1.68 × nadir was defined as the indicator of recurrent disease (p  1.68 × nadir at relapse (55.7 and 10.4 months; p = 0.04 and 0.01, respectively. The overall and progression free survival duration of patients with asymptomatic relapse and underwent a secondary CRS was longer than that of patients with symptomatic relapse (p = 0.02 and 0.04 respectively. Conclusions The increase of serum CA-125 levels is an early warning of clinical relapse in ovarian cancer. Using CA-125 levels in guiding the treatment of patients with asymptomatic recurrent ovarian cancer, who have shown CCR to primary therapy, can facilitate optimal secondary CRS and extend the survival duration of the patients.

    Purpose: To prospectively investigate the coronary artery status using coronary CT angiography (CCTA) in patients with Hodgkin lymphoma treated with combined modalities and mediastinal irradiation. Methods and Materials: All consecutive asymptomatic patients with Hodgkin lymphoma entered the study during follow-up, from August 2007 to May 2012. Coronary CT angiography was performed, and risk factors were recorded along with leukocyte telomere length (LTL) measurements. Results: One hundred seventy-nine patients entered the 5-year study. The median follow-up was 11.6 years (range, 2.1-40.2 years), and the median interval between treatment and the CCTA was 9.5 years (range, 0.5-40 years). Coronary artery abnormalities were demonstrated in 46 patients (26%). Coronary CT angiography abnormalities were detected in nearly 15% of the patients within the first 5 years after treatment. A significant increase (34%) occurred 10 years after treatment (P=.05). Stenoses were mostly nonostial. Severe stenoses were observed in 12 (6.7%) of the patients, entailing surgery with either angioplasty with stent placement or bypass grafting in 10 of them (5.5%). A multivariate analysis demonstrated that age at treatment, hypertension, and hypercholesterolemia, as well as radiation dose to the coronary artery origins, were prognostic factors. In the group of patients with LTL measurements, hypertension and LTL were the only independent risk factors. Conclusions: The findings suggest that CCTA can identify asymptomatic individuals at risk of acute coronary artery disease who might require either preventive or curative measures. Conventional risk factors and the radiation dose to coronary artery origins were independent prognostic factors. The prognostic value of LTL needs further investigation.

    The primary purpose of this study was to compare bone tracer uptake (BTU) on SPECT/CT in symptomatic and asymptomatic total hip arthroplasty (THA) and identify a possible relationship between BTU patterns and patient's symptoms. The secondary purpose was to investigate if the fixation methods (cemented versus uncemented) lead to different BTU patterns. A total of 58 THAs, 31 symptomatic (group S) and 27 asymptomatic (group AS), were prospectively collected and retrospectively analyzed. All symptomatic patients underwent standardized detailed history, clinical examination, radiographs and 99mTc-HDP SPECT/CT. BTU in SPECT/CT was quantified in three dimensions and anatomically localized in a scheme of quadrants and levels using a customized previously validated software. T tests were used on both quadrants and levels inside and between groups. A Pearson correlation was performed for BTU within the quadrants. An area under receiver operating characteristic curves was drawn in order to find a BTU value that could differentiate the two groups. Within the groups, patients with cemented and uncemented stems were compared for influences on BTU intensity. The causes of pain were identified in 61% of the patients. The most common problem was aseptic loosening (n = 12). In group AS, levels 1, 2 and 5 had similar BTUs. BTUs in these levels were significantly higher than in level 3, 4 and 6. In group S, no significant differences were seen in terms of BTU in level 1-5. However, BTU here was significantly higher than at level 6 (p < 0.001). In both groups, level 1, the superior, had a significantly higher BTU than level 2 (group AS p < 0.01, group S p < 0.05). Comparing the BTU of the two groups among levels, significant differences were found for level 4, level 5 and the entire stem areas (p < 0.05). The ROC curve calculated on the whole stem allowed identification of a BTU ratio of 3.1 that separated the 92.6% patients of group AS with BTU < 3.1 from the 54.8% of patients

    Sohn, Seil; Chung, Chun Kee; Kim, Yongjung Jay; Han, Inbo; Kang, Su Min; Yoon, Ji Won; Kim, Hyejin

    2017-06-01

    We aim to provide sagittal and pelvic parameters according to different age groups in an asymptomatic population all over 30 years old and to investigate the possible causes of changes in these parameters. Whole-spine, standing lateral radiographs were taken in 128 asymptomatic Korean people over 30 years old. The spinal parameters (the total thoracic kyphosis (TTK), maximal lumbar lordosis (MLL), total lumbar lordosis (TLL), lower lumbar lordosis (LLL), thoracolumbar junctional angle (TLJA), and lumbar inclination (LI)), pelvic parameters (pelvic incidence (PI), sacral slope (SS), and pelvic tilt (PT)), and spinal balance parameters (spinal balance, sacropelvic balance, and spinopelvic balance) were measured. The body mass index, body protein mass, waist line, skeletal muscle mass, and body fat mass were also measured for potential causes. TTK and TLJA were significantly increased in the group over 70 years of age compared to the other age groups (p = 0.0002, values were similar to PI even in over 70-year age group. LLL did not differ in the group over 70 years of age (p = 0.29), gradually increasing with an increase in age. SS was significantly decreased and PT was significantly increased in the group over 70 years of age as compared to the other age groups (p = 0.049, 0.049, respectively). PI was similar in all age groups (p = 0.75). Spinal balance was significantly decreased in the group over 70 years of age (p = mass and skeletal muscle mass (p = 0.01, 0.001, respectively). Body protein mass and skeletal muscle mass were significantly lower in the group over 70 years of age (p = 0.02, 0.02) and were possible causes. Several sagittal and pelvic parameters are different in asymptomatic adults over 70 years of age. Decreased body protein mass and skeletal muscle mass are possible causes of these changes.

    2012-07-01

    Full Text Available Abstract Background Inflammation plays an important role in coronary artery disease from the initiation of endothelial dysfunction to plaque formation to final rupture of the plaque. In this study, we investigated the potential pathophysiological and clinical relevance of novel cytokines secreted from various cells including adipocytes, endothelial cells, and inflammatory cells, in predicting coronary artery disease (CAD in asymptomatic subjects with type 2 diabetes mellitus. Methods We enrolled a total of 70 asymptomatic type 2 diabetic patients without a documented history of cardiovascular disease, and determined serum levels of chemerin, omentin-1, YKL-40, and sCD26. We performed coronary computed tomographic angiography (cCTA in all subjects, and defined coronary artery stenosis ≥ 50 % as significant CAD in this study. Results Subjects were classified into two groups: patients with suspected coronary artery stenosis on cCTA (group I, n = 41 and patients without any evidence of stenosis on cCTA (group II, n = 29. Group I showed significantly higher YLK-40 levels and lower HDL-C levels than group II (p = 0.038, 0.036, respectively. Levels of chemerin, omentin-1, and sCD26 were not significantly different between the two groups. Serum YKL-40 levels were positively correlated with systolic/diastolic BP, fasting/postprandial triglyceride levels, and Framingham risk score. Furthermore, YKL-40 levels showed moderate correlation with the degree of coronary artery stenosis and the coronary artery calcium score determined from cCTA. In multivariate logistic analysis, after adjusting for age, gender, smoking history, hypertension, and LDL-cholesterol, YLK-40 levels showed only borderline significance. Conclusions YKL-40, which is secreted primarily from inflammatory cells, was associated with several CVD risk factors and was elevated in type 2 diabetic patients with suspected coronary artery stensosis on cCTA. These results suggest

    The aim of this study was to use whole body cardiovascular magnetic resonance imaging (WB CVMR) to assess the heart and arterial network in a single examination, so as to describe the burden of atherosclerosis and subclinical disease in participants with symptomatic single site vascular disease. 64 patients with a history of symptomatic single site vascular disease (38 coronary artery disease (CAD), 9 cerebrovascular disease, 17 peripheral arterial disease (PAD)) underwent whole body angiogram and cardiac MR in a 3 T scanner. The arterial tree was subdivided into 31 segments and each scored according to the degree of stenosis. From this a standardised atheroma score (SAS) was calculated. Cine and late gadolinium enhancement images of the left ventricle were obtained. Asymptomatic atherosclerotic disease with greater than 50 % stenosis in arteries other than that responsible for their presenting complain was detected in 37 % of CAD, 33 % of cerebrovascular and 47 % of PAD patients. Unrecognised myocardial infarcts were observed in 29 % of PAD patients. SAS was significantly higher in PAD patients 24 (17.5-30.5) compared to CAD 4 (2–11.25) or cerebrovascular disease patients 6 (2-10) (ANCOVA p < 0.001). Standardised atheroma score positively correlated with age (β 0.36 p = 0.002), smoking status (β 0.34 p = 0.002), and LV mass (β -0.61 p = 0.001) on multiple linear regression. WB CVMR is an effective method for the stratification of cardiovascular disease. The high prevalence of asymptomatic arterial disease, and silent myocardial infarctions, particularly in the peripheral arterial disease group, demonstrates the importance of a systematic approach to the assessment of cardiovascular disease

    To determine sexually transmitted infection (STI) prevalence, and patient characteristics associated with detection of urethritis/cervicitis pathogens, among HIV-infected individuals offered voluntary STI screening at a South African HIV treatment center. Individuals, asymptomatic for genital discharge, were screened for Neisseria gonorrhoeae (NG), Chlamydia trachomatis, Trichomonas vaginalis (TV), Mycoplasma genitalium (MG) infections (real-time polymerase chain reaction assay), for syphilis and herpes simplex type 2 (serologically), and for bacterial vaginosis and Candida (microscopy, women only). Patients' most recent CD4 and viral load results were recorded. Demographic, clinical, and behavioral data were collected by nurse-administered questionnaire. Compared with men (n = 551), women (n = 558) were younger (mean age, 35.0 vs. 37.9 years; P urethritis/cervicitis pathogens detected (21.3% vs.16.4%, P = 0.035), and were less aware of their partner's HIV status (53.1% vs. 62.3%; P = 0.007). The overall prevalence of individual urethritis/cervicitis pathogens was TV (7.6%), MG (6.1%), NG (5.4%), and C. trachomatis (2.1%). Multivariate analysis highlighted 4 significant factors associated with the detection of specific urethritis/cervicitis pathogens, namely female gender (TV, adjusted odds ratio [aOR] 2.53, 95% confidence interval [CI]: 1.47-4.37), having a regular sexual partner in the past 3 months (NG, aOR 2.26, 95% CI: 1.01-5.08), suboptimal condom use with regular partners (TV, aOR 2.07, 95% CI: 1.25-3.42), and a history of genital warts in the past year (NG, 2.25, 95% CI: 1.26-4.03). Asymptomatic urethritis/cervicitis pathogens were highly prevalent in this population. Few urethritis/cervicitis pathogen-associated patient characteristics were identified, emphasizing the need for affordable STI diagnostics to screen HIV-infected patients.

    The goal of this study was to compare heart function and arrhythmia in clinically asymptomatic patients with beta thalassemia intermedia and beta thalassemia major. In this cross-sectional study, 60 patients with beta thalassemia major and 60 patients with beta thalassemia intermedia who had clinically no symptoms of arrhythmia and clinically normal heart function were evaluated using 24-hour ambulatory electrocardiogram monitoring and echocardiography. For data analysis SPSS ver.20 software was used. A P-value of less than 0.05 was considered statistically significant. The mean age of the beta thalassemia intermedia patients was 24.18 ± 7.9 years and the mean age in beta thalassemia major was 24.38 ± 7.7 years (P>0.05). Premature atrial contractions (PACs) were observed in 14 (23.3%) patients with beta thalassemia intermedia and in 22 (36.6%) beta thalassemia major patients. Premature ventricular contractions (PVCs) were detected in 8 (13.3%) patients in the beta thalassemia intermediate group and 16 (26.6) patients in the beta thalassemia major group, respectively. The left ventricular diastolic dimension, end-diastolic volume, and stroke volume were significantly higher in beta thalassemia intermedia group (Pintermedia group. Both atrial and ventricular arrhythmias were more common in the beta thalassemia major group. Higher end-diastolic volume and stroke volume were detected in the beta thalassemia intermedia group. Pulmonary acceleration time was lower in the beta thalassemia intermedia group, which can be an indicator of higher pulmonary pressure.

    A cross-sectional observational study to determine the response distribution, internal consistency, and construct, concurrent, and discriminative validities of The Scoliosis Research Society-22 (SRS-22) Patient Questionnaire translated into Japanese as compared with the other language versions. To validate the Japanese version of SRS22. The SRS-22 was translated into several languages but yet not into Japanese. The Japanese SRS-22 and Medical Outcomes Study Short Form 36 were simultaneously administered to 114 adolescent idiopathic scoliosis patients. Exploratory factor analysis revealed a 4-factor structure, though several items were not loaded as theoretically expected. The originally constructed Japanese SRS-22 subscales and the English version showed similar response distribution. Internal consistency was fair but lower than that of the English version. The concurrent validity of the translated version, except for the self-image subscale, was supported using Medical Outcomes Study Short Form 36 subscales as a reference. The function scale differed significantly by curve angle magnitude and treatment status. The self-image score was the highest in patients under observation when curve angle was or = 40 degrees, respectively. The Japanese SRS-22 is valid and may be useful for clinical evaluation of Japanese scoliosis patients, though the self-image subscale may need further assessment.

    Cerebrovascular events are frequently associated with hemodynamic disturbance caused by internal carotid artery (ICA) stenosis. It is challenging to determine the ischemia-related carotid stenosis during the intervention only using digital subtracted angiography (DSA). Inspired by the performance of well-established FFRct technique in hemodynamic assessment of significant coronary stenosis, we introduced a pressure-based carotid arterial functional assessment (CAFA) index generated from computational fluid dynamic (CFD) simulation in DSA data, and investigated its feasibility in the assessment of hemodynamic disturbance preliminarily using pressure-wired measurement and arterial spin labeling (ASL) MRI as references. The cerebral multi-delay multi-parametric ASL-MRI and carotid DSA including trans-stenotic pressure-wired measurement were implemented on a 65-year-old man with asymptomatic unilateral (left) ICA stenosis. A CFD simulation using simplified boundary condition was performed in DSA data to calculate the CAFA index. The cerebral blood flow (CBF) and arterial transit time (ATT) of ICA territories were acquired. CFD simulation showed good correlation (r = 0.839, P = 0.001) with slight systematic overestimation (mean difference - 0.007, standard deviation 0.017) compared with pressure-wired measurement. No significant difference was observed between them (P = 0.09). Though the narrowing degree of in the involved ICA was about 70%, the simulated and measured CAFA (0.942/0.937) revealed a functionally nonsignificant stenosis which was also verified by a compensatory final CBF (fronto-temporal/fronto-parietal region: 51.58/45.62 ml/100 g/min) and slightly prolonged ATT (1.23/1.4 s) in the involved territories, together with a normal left-right percentage difference (2.1-8.85%). The DSA based CFD simulation showed good consistence with invasive approach and could be used as a cost-saving and efficient way to study the relationship between

    The purpose of this study was to evaluate the prevalence of an abnormal stress myocardial perfusion study in a cohort of truly asymptomatic patients with type 2 diabetes mellitus using myocardial perfusion imaging by means of single photon emission computed tomography (SPECT). Secondly, we determined which clinical characteristics may predict an abnormal stress myocardial perfusion study in this population. A total of 120 asymptomatic patients (mean age 53{+-}10 years) with type 2 diabetes mellitus and one or more risk factors for coronary artery disease were prospectively recruited from an outpatient diabetes clinic. All patients underwent myocardial perfusion imaging by means of adenosine {sup 99m}Tc sestamibi SPECT. Images were evaluated for the presence of perfusion abnormalities as well as other nonperfusion abnormalities that may indicate extensive ischaemia, including left ventricular dysfunction (defined as a left ventricular ejection fraction <45%), transient ischaemic dilatation and adenosine-induced ST segment depression. Multivariable analysis was performed using a backward selection strategy to identify potential predictors for an abnormal stress myocardial perfusion study. Finally, all patients were followed up for 12 months to determine the occurrence of cardiovascular events: (1) cardiac death, (2) nonfatal myocardial infarction, (3) unstable angina requiring hospitalization, (4) revascularization, or (5) stroke. Of the 120 patients, 40 (33%) had an abnormal stress study, including myocardial perfusion abnormalities in 30 patients (25%). In 10 patients (8%), indicators of extensive (possibly balanced ischaemia) were observed in the absence of abnormal perfusion. The multivariable analysis identified current smoking, duration of diabetes and the cholesterol/high-density lipoprotein (HDL) ratio as independent predictors of an abnormal stress study. During a follow-up period of 12 months six patients (5%) had a cardiovascular event. The current study

    In the United-Kingdom, ≈1 of 2,000 persons could be infected with variant Creutzfeldt-Jakob disease (vCJD). Therefore, risk of transmission of vCJD by medical procedures remains a major concern for public health authorities. In this study, we used in vitro amplification of prions by protein misfolding cyclic amplification (PMCA) to estimate distribution and level of the vCJD agent in 21 tissues from 4 patients who died of clinical vCJD and from 1 asymptomatic person with vCJD. PMCA identified major levels of vCJD prions in a range of tissues, including liver, salivary gland, kidney, lung, and bone marrow. Bioassays confirmed that the quantitative estimate of levels of vCJD prion accumulation provided by PMCA are indicative of vCJD infectivity levels in tissues. Findings provide critical data for the design of measures to minimize risk for iatrogenic transmission of vCJD.

  5. Electrophysiology testing and catheter ablation are helpful when evaluating asymptomatic patients with Wolff-Parkinson-White pattern: the pro perspective.

    Pappone, Carlo; Santinelli, Vincenzo

    2015-09-01

    Important advances in the natural history and diagnosis of, and therapy for, asymptomatic Wolff-Parkinson-White (WPW) syndrome have been made in the last decade by our group. These data have necessitated revisiting current practice guidelines to decide on the optimal management of the asymptomatic WPW population. There has also been an emphasis on identifying initially asymptomatic individuals who are at risk by nationwide screening programs using the electrocardiogram for prophylactic catheter ablation to prevent the lifetime risk of sudden cardiac death, particularly in young asymptomatic people, because only a subgroup of them is at high risk, requiring early catheter ablation.

  6. Is there a role for coronary artery calcium scoring for management of asymptomatic patients at risk for coronary artery disease?: Clinical risk scores are not sufficient to define primary prevention treatment strategies among asymptomatic patients.

    Blaha, Michael J; Silverman, Michael G; Budoff, Matthew J

    2014-03-01

    Although risk factors have proven to be useful therapeutic targets, they are poor predictors of risk. Traditional risk scores are moderately successful in predicting future CHD events and can be a starting place for general risk categorization. However, there is substantial heterogeneity between traditional risk and actual atherosclerosis burden, with event rates predominantly driven by burden of atherosclerosis. Serum biomarkers have yet to show any clinically significant incremental value to the FRS and even when combined cannot match the predictive value of atherosclerosis imaging. As clinicians, are we willing to base therapy decisions on risk models that lack optimum-achievable accuracy and limit personalization? The decision to treat a patient in primary prevention must be a careful one because the benefit of therapy in an asymptomatic patient must clearly outweigh the potential risk. CAC, in particular, provides a personalized assessment of risk and may identify patients who will be expected to derive the most, and the least, net absolute benefit from treatment. Emerging evidence hints that CAC may also promote long-term adherence to aspirin, exercise, diet, and statin therapy. When potentially lifelong treatment decisions are on the line, clinicians must arm their patients with the most accurate risk prediction tools, and subclinical atherosclerosis testing with CAC is, at the present time, superior to any combination of risk factors and serum biomarkers.

    SPECT scanning using (99)Tc-TRODAT-1, a ligand that binds to dopamine transporters, may be useful for detection of early Parkinson's disease (PD), diagnosis of presymptomatic individuals, and monitoring disease progression. Understanding whether genetic factors contribute to inter-individual variability is crucial for interpreting imaging results in the context of disease pathophysiology. We tested whether polymorphisms in the genes for catechol-O-methyltransferase (COMT), monoamine-oxidase B (MAO-B), and the dopamine transporter (DAT) influence dopamine uptake parameters in the striatum in vivo in asymptomatic volunteers and patients with PD as measured with (99)Tc-TRODAT-1. (99)Tc-TRODAT-1 binding declined with age in both asymptomatic volunteers and PD patients, and depended on disease duration in PD patients. We found no significant association between COMT, MAO-B, and DAT polymorphisms and results of (99)Tc-TRODAT-1 testing in asymptomatic volunteers or patients with PD. In PD patients, the age of disease onset and speed of progression did not differ based on these polymorphisms. These results demonstrate that these specific genetic variations do not alter the fidelity of (99)Tc-TRODAT-1 as a measure of dopaminergic function in asymptomatic volunteer individuals or patients with PD.

    A randomized, placebo-controlled trial was designed to evaluate safety and immunogenicity of an anti-cytokine vaccine in high risk HIV-positive patients. This strategy was aimed to modulate the impaired cytokine regulation in AIDS. Twelve asymptomatic patients on antiretroviral therapy for at least 1 year and with CD4 cell counts between 100-300/mm3 were randomized to receive adjuvanted formol-inactivated interferon alpha-2a (IFN alpha) and continue the current antiretroviral treatment, whatever it was, or to receive the adjuvant alone and the current antiretroviral treatment. All patients received 4 i.m. injections monthly, followed by booster injections every 3 months. Clinical status, immunology and virology were monitored. Immune response to vaccination was evaluated in term of antibody detection (ELISA) and serum anti-IFN alpha neutralizing capacity. Only local discomfort and transient fever were reported. All vaccines except one showed increased levels of anti-IFN alpha Abs and developed serum IFN alpha neutralizing capacity. Viral load did not increase in vaccinees while it remained unchanged or even increased in placebo-treated patients. None of them showed HIV-related symptoms and all had their CD4 cell counts stabilized over 18 months, whereas 2 placebo-treated patients developed full-blow AIDS. In conclusion, anti-IFN alpha vaccine was safe and immunogenic. Stable clinical and immunological status over 18 months was observed in vaccinees coupled to increased serum IFN alpha neutralizing capacity.

    Patients with symptomatic Chiari malformation Type I (CM-I) typically exhibit a chronic, slowly progressive disease course with evolution of symptoms. However, some authors have reported acute neurological deterioration in the setting of CM-I and acquired Chiari malformations. Although brainstem dysfunction has been documented in patients with CM-II and hydrocephalus or shunt malfunction, to the authors' knowledge only 1 report describing ventriculoperitoneal (VP) shunt malfunction causing neurological deterioration in a patient with CM-I exists. The authors report on their experience with the treatment of previously asymptomatic CM-I in 2 children who experienced quite different manifestations of acute neurological deterioration secondary to VP shunt malfunction. Presumably, VP shunt malfunction created a positive rostral pressure gradient across a stenotic foramen magnum, resulting in tetraparesis from foramen magnum syndrome in 1 patient and acute ataxia and cranial nerve deficits from syringobulbia in the other. Although urgent shunt revisions yielded partial recovery of neurological function in both patients, marked improvement occurred only after posterior fossa decompression.

  11. Modest elevation in BNP in asymptomatic hypertensive patients reflects sub-clinical cardiac remodeling, inflammation and extracellular matrix changes.

    Phelan, Dermot

    2012-11-01

    In asymptomatic subjects B-type natriuretic peptide (BNP) is associated with adverse cardiovascular outcomes even at levels well below contemporary thresholds used for the diagnosis of heart failure. The mechanisms behind these observations are unclear. We examined the hypothesis that in an asymptomatic hypertensive population BNP would be associated with sub-clinical evidence of cardiac remodeling, inflammation and extracellular matrix (ECM) alterations. We performed transthoracic echocardiography and sampled coronary sinus (CS) and peripheral serum from patients with low (n = 14) and high BNP (n = 27). Peripheral BNP was closely associated with CS levels (r = 0.92, p<0.001). CS BNP correlated significantly with CS levels of markers of collagen type I and III turnover including: PINP (r = 0.44, p = 0.008), CITP (r = 0.35, p = 0.03) and PIIINP (r = 0.35, p = 0.001), and with CS levels of inflammatory cytokines including: TNF-α (r = 0.49, p = 0.002), IL-6 (r = 0.35, p = 0.04), and IL-8 (r = 0.54, p<0.001). The high BNP group had greater CS expression of fibro-inflammatory biomarkers including: CITP (3.8±0.7 versus 5.1±1.9, p = 0.007), TNF-α (3.2±0.5 versus 3.7±1.1, p = 003), IL-6 (1.9±1.3 versus 3.4±2.7, p = 0.02) and hsCRP (1.2±1.1 versus 2.4±1.1, p = 0.04), and greater left ventricular mass index (97±20 versus 118±26 g\\/m(2), p = 0.03) and left atrial volume index (18±2 versus 21±4, p = 0.008). Our data provide insight into the mechanisms behind the observed negative prognostic impact of modest elevations in BNP and suggest that in an asymptomatic hypertensive cohort a peripheral BNP measurement may be a useful marker of an early, sub-clinical pathological process characterized by cardiac remodeling, inflammation and ECM alterations.

    Atherosclerosis is a systemic inflammatory disease intertwined with neovascularization. Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) enables the assessment of plaque neovascularization. This study aimed to explore the systemic nature of atherosclerosis by assessing difference in severity of neovascularization as quantified by DCE-MRI of vertebral arteries (VAs) between patients with symptomatic and asymptomatic carotid artery disease. Ten consecutive patients with asymptomatic VA stenosis and concomitant symptomatic carotid artery disease (group 1) and 10 consecutive patients with asymptomatic VA stenosis and concomitant asymptomatic carotid artery disease (group 2) underwent 3-dimensional DCE-MRI of their cervical segment of VAs. A previously validated pharmacokinetic modeling approach was used for DCE-MRI analysis. K trans was calculated in the adventitia and plaque as a measure of neovessel permeability. Both patient groups were comparable for demographics and comorbidities. Mean luminal stenosis was comparable for both groups (54.4% versus 52.27%, P = .32). Group 1 had higher adventitial K trans and plaque K trans (.08 ± .01 min -1 , .07 ± .01 min -1 ) compared with Group 2 (.06 ± .01 min -1 , .06 ± .01 min -1 ) (P = .004 and .03, respectively). Good correlation was present among the two image analysts (intraclass correlation coefficient = .78). Vertebral Artery atheroma of patients with symptomatic carotid artery disease had increased neovessel permeability compared with the patients with asymptomatic carotid artery disease. These findings are consistent with the hypothesis that atherosclerosis is a systemic inflammatory disease. The VA atherosclerosis is likely to have increased severity of neovascularization if another arterial territory is symptomatic in the same patient cohort.

  14. Population Pharmacokinetics of Hydroxychloroquine in Japanese Patients With Cutaneous or Systemic Lupus Erythematosus.

    Morita, Shigemichi; Takahashi, Toshiya; Yoshida, Yasushi; Yokota, Naohisa

    2016-04-01

    Hydroxychloroquine (HCQ) is an effective treatment for patients with cutaneous lupus erythematosus (CLE) or systemic lupus erythematosus (SLE) and has been used for these patients in more than 70 nations. However, in Japan, HCQ has not been approved for CLE or SLE. To establish an appropriate therapeutic regimen and to clarify the pharmacokinetics (PK) of HCQ in Japanese patients with CLE with or without SLE (CLE/SLE), a population pharmacokinetic (PopPK) analysis was performed. In a clinical study of Japanese patients with a diagnosis of CLE irrespective of the presence of SLE, blood and plasma drug concentration-time data receiving multiple oral doses of HCQ sulfate (200-400 mg daily) were analyzed using nonlinear mixed-effects model software. The blood and plasma concentrations of HCQ were analyzed using a high-performance liquid chromatography tandem mass spectrometry method. Model evaluation and validation were performed using goodness-of-fit (GOF) plots, visual predictive check, and a bootstrap. The PopPKs of HCQ in the blood and plasma of 90 Japanese patients with CLE/SLE were well described by a 1-compartment model with first-order absorption and absorption lag time. Body weight was a significant (P < 0.001) covariate of oral clearance of HCQ. The final model was assessed using GOF plots, a bootstrap, and visual predictive check, and this model was appropriate. Simulations based on the final model suggested that the recommended daily doses of HCQ sulfate (200-400 mg) based on the ideal body weight in Japanese patients with CLE/SLE were in the similar concentration ranges. The PopPK models derived from both blood and plasma HCQ concentrations of Japanese patients with CLE/SLE were developed and validated. Based on this study, the dosage regimens of HCQ sulfate for Japanese patients with CLE/SLE should be calculated using the individual ideal body weight.

    Background Targeting HER-2/neu with Trastuzumab has been associated with development of cardiac toxicity. Methods Twenty-seven patients with ductal carcinoma in situ (DCIS) of the breast completed an IRB approved clinical trial of a HER-2/neu targeted dendritic cell based vaccine. Four weekly vaccinations were administered prior to surgical resection. All subjects underwent pre- and post-vaccine cardiac monitoring by MUGA/ECHO scanning allowing for a comparison of cardiac function. Results In 3 of 27 vaccinated patients (11%) transient asymptomatic decrements in ejection fraction of greater than 15% were noted after vaccination. Notably, evidence of circulating anti-HER-2/neu antibody was found prior to vaccination in all three patients, but cardiac toxicity was not noted until induction of cellular mediated immune responses. Conclusions This is the first description of HER-2/neu targeted vaccination associated with an incidence of cardiac changes, and the induction of cellular immune responses combined with antibody may contribute to changes in cardiac function.

    The aim of the present study was non-invasive evaluation of the cardiovascular system in asymptomatic young adult patients with juvenile localized scleroderma (JLS) and juvenile systemic sclerosis (JSS). A group of 34 consecutive children with scleroderma were prospectively observed in the study. The control group (CG) consisted of 20 healthy subjects. In each subject 12-lead electrocardiographic, echocardiographic, ECG Holter, and ambulatory blood pressure monitoring examinations were performed at the baseline visit and after 10 years. Additionally, B-type natriuretic peptide (BNP) concentrations were measured after 10 years. Examinations were performed in 13 patients with JLS and 15 with JSS at the final visit. Two children had died (one from each group). Four patients were alive but refused the final visit. After 10 years, a higher prevalence of ventricular extrasystoles (p = 0.01) and an elevated pulmonary arterial pressure (JLS: p = 0.04, JSS: p = 0.03) were observed in both groups, but in comparison with the controls there was no significant difference at the final visit. In JLS patients more cases of left ventricle diastolic dysfunction, hypertension, and sinus tachycardia were diagnosed at the final visit (p ≤ 0.05). More atrioventricular block episodes in both groups of scleroderma patients were observed. Over the 10 years, arterial hypertension was diagnosed in three patients from the JLS group and in two with JSS. There were no significant differences in BNP concentrations at the final visit. The results of the present study show that juvenile scleroderma seems to be more benign than adult-onset disease. This observational study shows subclinical, not severe, cardiac abnormalities in adult patients with juvenile-onset disease.

    Few studies have examined ultrasound imaging of abdominal manifestations of HIV-AIDS, although these rank second only to its pleuropulmonary manifestations. Thus, this study sought to determine the features of abdominal ultrasound in HIV infection. This prospective, descriptive and analytical study took place in the radiology department of the University Hospital Campus Lomé and covered the three-year period of 2009-2011. It included all patients older than 15 years with positive HIV serology. During the study period, 566 patients met the inclusion criteria. Ultrasound examination showed the liver appeared normal in 153 patients (27.0%), but homogeneously hyperechoic and thus suggestive of hepatic steatosis in 107 (18.9%). The bile duct was dilatated in 12 patients or 2.1%. An anomaly in the corticomedullary differentiation in normal-sized kidneys was noted in 28.1% (159 patients). Diffuse homogeneous hypertrophy of the pancreas was found in 3 patients (0.53%). Splenomegaly was noted in 387 patients (68.4%); the echopattern of the spleen was diffusely micronodular in 6 patients (1.1%). Deep adenopathies were found in 29 patients (5.1%) and ascites in 46 patients (8.1%). Abdominal ultrasound is a medical imaging technique available in developing countries, less expensive than others, which can be considered an alternative to computed tomography (CT) in the countries of sub-Saharan Africa for the exploration of the abdominal manifestations of HIV.

    Differences in muscle activity patterns between patients with symptomatic and asymptomatic full-thickness rotator cuff tears have not yet been fully clarified. The purpose of this study was to investigate the muscle activity pattern by use of positron emission tomography (PET) in patients with symptomatic and asymptomatic rotator cuff tears. Ten shoulders of 9 patients with full-thickness rotator cuff tears were divided into 2 groups by a numerical pain rating scale (0-10), symptomatic (≥2) and asymptomatic (0 or 1), with 5 shoulders each. Scaption exercise of bilateral arms (200 repetitions in 10 minutes) with a weight of 0.25 kg each was performed before and after injection of fluorodeoxyglucose. After PET examination, the standardized uptake value of each muscle was calculated to quantify its activity and compared between the two groups. The activity of the anterior and middle deltoid was significantly decreased in the symptomatic group compared with the asymptomatic group (anterior deltoid, P = .02; middle deltoid, P = .03). In contrast, the activity of the superior trapezius was significantly increased in the symptomatic group compared with the asymptomatic group (P = .02). In patients with a symptomatic tear, the deltoid activity was decreased and the trapezius activity was increased. It is likely that they might have moved the painful glenohumeral joint less and instead moved the painless scapulothoracic joint more during the prescribed exercise. We conclude that patients with painful rotator cuff tears use the parascapular muscles more than those without pain do during arm elevation.

    Cranial MRI findings in four patients who had hepatic dysfunction, including one with sole hepatic form of Wilson`s disease, were reported. The MR examinations revealed bilateral, symmetric hyperintensity in the globus pallidus, subthalamic nuclei and mesencephalon on T1-weighted images with no corresponding abnormality on T2-weighted sequences. The basal ganglia were normal on CT examinations in all patients. None of the patients had the clinical findings of hepatic encephalopathy. The MR findings in our patients did not correlate with the degree or duration of hepatic dysfunction. (orig.)

  1. Asymptomatic proteinuria. Clinical significance.

    Papper, S

    1977-09-01

    Patients with asymptomatic proteinuria have varied reasons for the proteinuria and travel diverse courses. In the individual with normal renal function and no systemic cause, ie, idiopathic asymptomatic proteinuria, the outlook is generally favorable. Microscopic hematuria probably raises some degree of question about prognosis. The kidney shows normal glomeruli, subtle changes, or an identifiable lesion. The initial approach includes a clinical and laboratory search for systemic disease, repeated urinalyses, quantitative measurements of proteinuria, determination of creatinine clearance, protein electrophoresis where indicated, and intravenous pyelography. The need for regularly scheduled follow-up evaluation is emphasized. Although the initial approach need not include renal biopsy, a decline in creatinine clearance, an increase in proteinuria, or both are indications for biopsy and consideration of drug therapy.

    The study aimed to analyze the professional autonomy of Japanese nurses when caring for non-Japanese patients and to identify its contributing factors. A descriptive cross-sectional design was used. Participants included 238 clinical nurses working at 27 hospitals in Japan. The Intercultural Sensitivity Scale (Chen and Starosta), and the Scale for Professional Autonomy in Nursing (Kikuchi and Harada) were used to measure intercultural sensitivity and professional autonomy. Stepwise multiple regression analysis was used to identify the most significant factors affecting professional autonomy. Professional autonomy of Japanese nurses caring for non-Japanese patients was significantly lower than when caring for Japanese patients (142.84 vs. 172.85; p autonomy of Japanese nurses by promoting intercultural sensitivity. © The Author(s) 2015.

    Obtaining serum troponin levels in every patient with acute stroke is recommended in recent stroke guidelines, but there is no evidence that these contribute positively to clinical care. We sought to determine the clinical significance of measuring troponin levels in acute ischemic stroke patients. We reviewed 398 consecutive patients with acute ischemic stroke at a large academic institution from 2010 to 2012. Troponin levels were measured as a result of protocol in place during part of the study period. The mean age was 70 years (standard deviation ±16 years) and 197 (49.5%) were men. Chronic kidney disease was present in 78 (19.6%), coronary artery disease in 107 (26.9%), and atrial fibrillation in 107 (26.9%). Serum troponin T was measured in 246 of 398 patients (61.8%). Troponin was elevated (>.01 ng/mL) at any point in 38 of 246 patients (15.5%) and was elevated in 28 patients at all 3 measurements (11.3% of those with troponin measured). Only 4 of 246 patients (1.6%) had a significant uptrend. Two were iatrogenic in the setting of hemodynamic augmentation using vasopressors to maintain cerebral perfusion. One case was attributed to stroke and chronic kidney disease and another case to heart failure from inflammatory fibrocalcific mitral valvular heart disease. Serum troponin elevation in patients with ischemic stroke is not usually caused by clinically significant acute myocardial ischemia unless iatrogenic in the setting of vasopressor administration. Serum troponin levels should be measured judicially, based on clinical context, rather than routinely in all stroke patients. Copyright © 2016 National Stroke Association. Published by Elsevier Inc.

    2016-12-15

    Diabetes mellitus is a multisystem disease which weakens the human's immunity. Subsequently, it worsens the sequelae of apical periodontitis by raising a fierce bacterial trait due to the impaired host response. This study aimed to estimate bacterial reduction after using different irrigation techniques in systemically healthy and diabetic patients with asymptomatic apical periodontitis. Enterococcus faecalis , Peptostreptococcus micros , and Fusobacterium necleatum bacteria were chosen, as they are the most common and prevailing strains found in periodontitis. Bacterial samples were retrieved from necrotic root canals of systemically healthy and diabetic patients, before and after endodontic cleaning and shaping by using two different irrigation techniques; the conventional one and the EndoVac system. Quantitive polymerase chain reaction (qPCR) was utilised to detect the reduction in the bacterial count. The EndoVac irrigation system was effective in reducing bacteria, especially Peptostreptococcus micros in the diabetic group when compared to conventional irrigation technique with a statistically significant difference. The EndoVac can be considered as a promising tool in combination with irrigant solution to defeat the bacterial colonies living in the root canal system. Additional studies ought to be done to improve the means of bacterial clearance mainly in immune-compromised individuals.

    ABSTRACT Diabetes is a very frequent disease and it is estimated that its prevalence will continuously increase during the next two decades. The arteriosclerotic process in diabetic patients progresses earlier and more diffusely, and it is more accelerated in the diabetic patient than in the overall population. In diabetic subjects, acute myocardial infarction (AMI) and stroke are the leading causes of death, but the presence of arterial disease is not always detected before the development o...

    Patients with schizophrenia have been reported to perform worse than non-schizophrenic populations on neuropsychological tests, which may be affected by cultural factors. The aim of this study was to examine the performance of a sizable number of patients with schizophrenia on the Japanese version of the Wechsler Adult Intelligence Scale-III (WAIS-III) compared with healthy controls. Performance on the WAIS-III was evaluated in 157 Japanese patients with schizophrenia and in 264 healthy control subjects. All IQ scores and four indices from the WAIS-III were impaired for patients with schizophrenia compared with healthy controls. Processing Speed was markedly disturbed, approximately 2 SD below that of the healthy control group. Among the 13 subtests, Comprehension (z = -1.70, d = 1.55), Digit Symbol Coding (z = -1.84, d = 1.88), and Symbol Search (z = -1.85, d = 1.77) were profoundly impaired relative to the healthy controls. These results indicate that the pattern and degree of impairment, as evaluated by the WAIS-III, in Japanese patients are similar to those previously reported in English-speaking patients and that the deficits of some neuropsychological domains relevant to functional outcomes are universally characteristic of schizophrenia. © 2014 The Authors.

    Xiaofen Ma

    Full Text Available This study aimed to investigate the topological organization of intrinsic functional brain networks in patients with end-stage renal disease (ESRD.Resting-state functional MRI data were collected from 22 patients with ESRD (16 men, 18-61 years and 29 age- and gender-matched healthy controls (HCs, 19 men, 32-61 years. Whole-brain functional networks were obtained by calculating the interregional correlation of low-frequency fluctuations in spontaneous brain activity among 1,024 parcels that cover the entire cerebrum. Weighted graph-based models were then employed to topologically characterize these networks at different global, modular and nodal levels.Compared to HCs, the patients exhibited significant disruption in parallel information processing over the whole networks (P < 0.05. The disruption was present in all the functional modules (default mode, executive control, sensorimotor and visual networks although decreased functional connectivity was observed only within the default mode network. Regional analysis showed that the disease disproportionately weakened nodal efficiency of the default mode components and tended to preferentially affect central or hub-like regions. Intriguingly, the network abnormalities correlated with biochemical hemoglobin and serum calcium levels in the patients. Finally, the functional changes were substantively unchanged after correcting for gray matter atrophy in the patients.Our findings provide evidence for the disconnection nature of ESRD's brain and therefore have important implications for understanding the neuropathologic substrate of the disease from disrupted network organization perspective.

  12. T cell subtypes and reciprocal inflammatory mediator expression differentiate P. falciparum memory recall responses in asymptomatic and symptomatic malaria patients in southeastern Haiti.

    Jason S Lehmann

    Full Text Available Asymptomatic Plasmodium falciparum infection is responsible for maintaining malarial disease within human populations in low transmission countries such as Haiti. Investigating differential host immune responses to the parasite as a potential underlying mechanism could help provide insight into this highly complex phenomenon and possibly identify asymptomatic individuals. We performed a cross-sectional analysis of individuals who were diagnosed with malaria in Sud-Est, Haiti by comparing the cellular and humoral responses of both symptomatic and asymptomatic subjects. Plasma samples were analyzed with a P. falciparum protein microarray, which demonstrated serologic reactivity to 3,877 P. falciparum proteins of known serologic reactivity; however, no antigen-antibody reactions delineating asymptomatics from symptomatics were identified. In contrast, differences in cellular responses were observed. Flow cytometric analysis of patient peripheral blood mononuclear cells co-cultured with P. falciparum infected erythrocytes demonstrated a statistically significant increase in the proportion of T regulatory cells (CD4+ CD25+ CD127-, and increases in unique populations of both NKT-like cells (CD3+ CD8+ CD56+ and CD8mid T cells in asymptomatics compared to symptomatics. Also, CD38+/HLA-DR+ expression on γδ T cells, CD8mid (CD56- T cells, and CD8mid CD56+ NKT-like cells decreased upon exposure to infected erythrocytes in both groups. Cytometric bead analysis of the co-culture supernatants demonstrated an upregulation of monocyte-activating chemokines/cytokines in asymptomatics, while immunomodulatory soluble factors were elevated in symptomatics. Principal component analysis of these expression values revealed a distinct clustering of individual responses within their respective phenotypic groups. This is the first comprehensive investigation of immune responses to P. falciparum in Haiti, and describes unique cell-mediated immune repertoires that

    1995-07-01

    The aim of this prospective study was to evaluate the frequency of postoperative fluid collection after laparoscopic appendectomy in patients with normal postoperative development. Twenty-eight patients were included. The surgical technique, histological data, and postoperative development during the first postoperative month were recorded. A sonographic analysis was performed on the 5th postoperative day by a radiologist who was not aware of the histological and surgical data. Ten cases of fluid collection were found (37%). The frequency was higher in cases of suppurated appendicitis and significantly higher with associated periappendicitis. Peritoneal irrigation or retrocecal dissection did not influence the occurrence of fluid collection. Postoperative serous fluid collection occurs with a high frequency after laparoscopic appendectomies, and one must be careful in interpreting sonographic analyses in looking for deep abscesses in patients with difficult postoperative development.

    Many studies highlight that an impaired ability to communicate is one of the key clinical features of Alzheimer disease (AD). To study temporal organisation of speech in an oral reading task in patients with AD and in matched healthy controls using a semi-automatic method, and evaluate that method's ability to discriminate between the 2 groups. A test with an oral reading task was administered to 70 subjects, comprising 35 AD patients and 35 controls. Before speech samples were recorded, participants completed a battery of neuropsychological tests. There were no differences between groups with regard to age, sex, or educational level. All of the study variables showed impairment in the AD group. According to the results, AD patients' oral reading was marked by reduced speech and articulation rates, low effectiveness of phonation time, and increases in the number and proportion of pauses. Signal processing algorithms applied to reading fluency recordings were shown to be capable of differentiating between AD patients and controls with an accuracy of 80% (specificity 74.2%, sensitivity 77.1%) based on speech rate. Analysis of oral reading fluency may be useful as a tool for the objective study and quantification of speech deficits in AD. Copyright © 2012 Sociedad Española de Neurología.

    2015-09-01

    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. © 2015 Japanese Dermatological Association.

    2017-10-01

    Full Text Available Introduction: The infections of female genital tract, especially the cervix are asymptomatic in presentation and pose a diagnostic challenge. Vaginal infections can lead to cytoplasmic and nuclear abnormalities in the epithelial cells. Additionally, these infections could augur an inflammatory response of varying nature. The most common flora include Candida albicans, Gardnerella vaginalis, Trichomonas vaginalis, Human Papilloma Virus (HPV, Human Herpes Virus (HHV and Actinomyces sp. Aim: This study seeks to measure the role of Papanicolaou smear in detection of pathologic flora: Candida albicans, Gardnerella vaginalis, Trichomonas vaginalis, HPV, HHV and Actinomyces; in a rural health care set up amongst women in the reproductive and menopausal age group. Materials and Methods: A retrospective study of cervical smears by Papanicolaou method, over a 14 month period was carried out in a tertiary care centre including a total number of 150 patients. Results: Of the total of 150 samples examined, Candida species was the most frequently detected (8.7% followed by Trichomonas vaginalis (5.3% and Gardnerella vaginalis species (4.7%. HPV-induced changes were noted in a mere 2% of cases. Actinomyces species was noted in less than 1% of cases. Conclusion: The Papanicolaou test for examining cervical smear has definite uses in detecting vaginal microorganisms. Apart from detection of the usual pathogenic flora, the test has utility in defining the degree of inflammation and additional reparative changes.

    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.

    The cyclin D-CDK4/6-INK4-Rb pathway is frequently dysregulated in cancers. Ribociclib, an orally available, selective CDK4/6 inhibitor, showed preliminary clinical activity in a phase I study in the USA and Europe for patients with solid tumors and lymphomas. The present study aimed to determine the single-agent maximum tolerated dose (MTD) and recommended dose for expansion (RDE) in Japanese patients with advanced solid tumors. Ribociclib safety, tolerability, pharmacokinetic profile, and preliminary antitumor activity were also assessed. Japanese patients with solid tumors that had progressed on prior therapies received escalating doses of single-agent ribociclib on a 3-weeks-on/1-week-off schedule. Treatment continued until the development of toxicity or disease progression. A dose escalation was planned for patients with esophageal cancer. In the dose-escalation phase, 4 patients received 400 mg ribociclib and 13 patients received 600 mg ribociclib. Four patients experienced dose-limiting toxicities, 3 of whom were in the 600 mg group. The RDE was declared to be 600 mg, and the MTD was not determined. The most frequent adverse events were hematologic and gastrointestinal. Four patients achieved stable disease at the 600 mg dose; no patients achieved complete or partial response. All patients discontinued the study, the majority due to disease progression. No patients discontinued due to adverse events. Dose escalation was not pursued due to lack of observed efficacy in esophageal cancer. At the RDE of 600 mg/d on a 3-weeks-on/1-week-off schedule, ribociclib showed acceptable safety and tolerability profiles in Japanese patients with advanced solid tumors. © 2017 The Authors.

    2018-04-01

    Functional evaluation of sensorimotor function of the shoulder joint is important for guidance of sports-specific training, prevention and rehabilitation of shoulder instability. Such assessment should be multimodal and comprise all qualities of sensorimotor shoulder function. This study evaluates feasibility of such multimodal assessment of glenohumeral sensorimotor function in patients with shoulder instability and handball players. Nine patients with untreated anterior instability of their dominant shoulder and 15 asymptomatic recreational handball players performed proprioceptive joint position sense and dynamic stabilization evaluations on an isokinetic device, as well as a functional throwing performance task. Outcome measures were analysed individually and equally weighted in a Shoulder-Specific Sensorimotor Index (S-SMI). Finally, isokinetic strength evaluations were conducted. We observed comparable sensorimotor functions of unstable dominant shoulders compared to healthy, contralateral shoulders (e.g. P=0.59 for S-SMI). Handball players demonstrated superior sensorimotor function of their dominant shoulders exhibiting a significantly higher throwing performance and S-SMI (P0.22). The present study proves feasibility of multimodal assessment of shoulder sensorimotor function in overhead athletes and patients with symptomatic anterior shoulder instability. Untreated shoulder instability led to a loss of dominance-related sensorimotor superiority indicating functional internal rotation deficiency. Dominant shoulders of handball players showed a superior overall sensorimotor function but weakness of dominant internal rotation constituting a risk factor for occurrence of posterior superior impingement syndrome. The S-SMI could serve as a diagnostic tool for guidance of sports-specific training, prevention and rehabilitation of shoulder instability.

    Prognostic value of additional carotid Doppler evaluations to carotid intima-media thickness (IMT) and plaque has not been completely evaluated. A total of 1119 patients with risk factors for, but without, overt coronary artery disease (CAD), who underwent both carotid ultrasound and Doppler examination were included in the present study. Parameters of interest included peak systolic and end-diastolic velocities, resistive indices of the carotid arteries, IMT, and plaque measurements. The primary end-point was all-cause cerebro-cardiovascular events (CVEs) including acute myocardial infarction, coronary revascularization therapy, heart failure admission, stroke, and cardiovascular death. Model 1 covariates comprised age and sex; Model 2 also included hypertension, diabetes and smoking; Model 3 also had use of aspirin and statin; and Model 4 also included IMT and plaque. The mean follow-up duration was 1386±461 days and the mean age of the study population was 60±12 years. Amongst 1119 participants, 43% were women, 57% had a history of hypertension, and 23% had diabetes. During follow-up, 6.6% of patients experienced CVEs. Among carotid Doppler parameters, average common carotid artery end-diastolic velocity was the independent predictor for future CVEs after adjustments for all models variables (HR 0.95 per cm/s, 95% confident interval 0.91-0.99, p=0.034 in Model 4) and significantly increased the predictive value of Model 4 (global χ(2)=59.0 vs. 62.8, p=0.029). Carotid Doppler measurements in addition to IMT and plaque evaluation are independently associated with future CVEs in asymptomatic patients at risk for CAD.

    The radiologic findings of a single nodule from Pneumocystis jirovecii pneumonia (PJP) have been rarely reported. We described a case of granulomatous PJP manifesting as a solitary pulmonary nodule with a halo sign in a 69-year-old woman with diffuse large B cell lymphoma during chemotherapy. The radiologic appearance of the patient suggested an infectious lesion such as angioinvasive pulmonary aspergillosis or lymphoma involvement of the lung; however, clinical manifestations were not compatible with the diseases. The nodule was confirmed as granulomatous PJP by video-assisted thoracoscopic surgery biopsy.

    Full Text Available A 14-year-old boy underwent emergency debridement surgery of right foot under spinal anaesthesia. Four hours after the surgery, the patient developed symptoms of cauda equina syndrome (CES. Postoperative magnetic resonance imaging of the patient′s spine suggested underlying tubercular arachnoiditis. The boy was started on intravenous methylprednisolone and antitubercular therapy. He responded to the therapy and recovered completely in 2 weeks without any residual neurological deficits. We suggest that underlying pathological changes in the subarachnoid space due to tubercular arachnoiditis contributed to maldistribution of the local anaesthetic drug leading to CES.

    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 gastritis changed from antrum-predominant gastritis to corpus-predominant gastritis with age in both populations. CONCLUSION: Gastric cancer was located in the upper part of the stomach in half of the Mongolian patients; Mongolian patients were infected with non-East-Asian-type H. pylori. PMID:26217093

    Several reports have suggested that multilingualism has a protective effect against semantic dementia. Here, we provide further evidence for this effect. The patient was a 75-year-old right-handed Taiwanese woman who had retired after working as a tailor. She was able to speak Taiwanese, Japanese and Mandarin Chinese fluently until 5 years ago. She gradually developed symptoms of profound anomia and difficulty with word-finding. Her mother tongue was Taiwanese and she had learned Japanese as her first symbolized language. She had used Mandarin Chinese for most of her life, but depended on Japanese to read and write (such as reading a newspaper and keeping accounts). However, she could now speak only very simple Taiwanese and Japanese, and could recognize only simple Japanese characters. SECOND: The patient was a 62-year-old right-handed man who had worked as an ironworker. He could speak Taiwanese and Mandarin Chinese fluently until 5 years ago. His mother tongue was Taiwanese. After 5 years of language deterioration, he was unable to communicate with his family members or recognize any characters, including numbers. SPECT RESULTS: Brain perfusion ECD SPECT (Tc-99m-ethyl cysteinate dimer single-photon emission computed tomography) showed less perfusion in the multilingual patient (Case #1) than in the bilingual patient (Case #2). Neuropsychological tests also demonstrated a slower rate of degeneration in the multilingual patient. We speculate that reading and writing in Japanese had a greater impact on the semantic system in Case #1. Thus, this patient showed relatively less degeneration or functional inactivity, as shown by perfusion in the frontal lobe, and this might be due to the persistent activation involved in multilingualism.

    The incidence of early-onset (under 50 years of age) colorectal cancer (CRC) in the Vietnamese has been reported to be quite higher than that in the Japanese. To clarify the differences in genetic alterations between Vietnamese and Japanese CRCs, we investigated mutations in K-ras and mitochondrial DNA (mtDNA) and high-frequency microsatellite instability (MSI-H) in the CRCs of Vietnamese and Japanese patients. We enrolled 60 Vietnamese and 233 Japanese patients with invasive CRCs. DNA was extracted from formalin-fixed, paraffin-embedded tissue sections. K-ras mutations were examined with PCR-single-strand conformation polymorphism analysis. mtDNA mutations and MSI-H were examined with microsatellite analysis using D310 and BAT-26, respectively. K-ras mutations were examined in 60 Vietnamese and 45 Japanese CRCs. The frequency of the mutations in the Vietnamese CRCs was significantly higher than that in the Japanese CRCs (8 of 24 [33%] vs 5 of 45 [11%], p =0.048). MSI-H was examined in 60 Vietnamese and 130 Japanese CRCs. The frequency of MSI-H in the Vietnamese CRCs was also significantly higher than that in the Japanese CRCs (6 of 27 [22%] vs 10 of 130 [8%], p =0.030). mtDNA mutations were examined in 60 Vietnamese and 138 Japanese CRCs. The frequency of mtDNA mutations in the Vietnamese CRCs was significantly higher than that in the Japanese CRCs (19 of 44 [43%] vs 11 of 133 [9%], p Vietnamese and Japanese patients. These results indicate that the developmental pathways of CRCs in the Vietnamese may differ from those of CRCs in the Japanese.

    2006-10-01

    This prospective study was conducted to determine the flare up rate related to root canal treatment of asymptomatic non vital maxillary central incisor teeth performed in one and two appointments and the relationship, if any between pain and number of treatment visits. The frequency of postobturation pain and swelling was recorded and evaluated over an observation period of 1 week in a 120 consecutive patients undergoing root canal treatment. The patients were assigned randomly into one of two groups of 60 patients each. The canals of all teeth were prepared and filled using the step-back preparation and lateral condensation filling techniques. The data were analyzed statistically using Mann-Whitney test. Eight of the 120 patients were excluded from the analysis as they failed to attend for postoperative reviews. Out of the 112 patients involved in the study 90 patients had no pain, 9 patients had slight pain, 8 patients had moderate pain, and 5 patients had severe pain after 2 days. After 7 days 104 patients had no pain, 4 patients had slight pain, 3 patients had moderate pain and 1 patient had severe pain. No statistically significant difference in the incidence and degree of postoperative pain was found between one and two visit Endodontic procedures. The rate of post obturation flare up in asymptomatic Endodontically treated non vital maxillary centarl incisors was 11.6 and 3.6% after 2 and 7 days, respectively.

    Seizure threshold (ST) in electroconvulsive therapy (ECT) has not been reported previously in Japanese patients. We investigated ST in bilateral ECT in Japanese patients using the dose-titration method. The associations between demographic and clinical characteristics and ST were analyzed to identify the predictors of ST. Finally, the validity of the half-age method for the stimulus dose was evaluated. Fifty-four Japanese patients with mood disorder, schizophrenia, and other psychotic disorders received an acute course of bilateral ECT using a brief-pulse device. ST was determined at the first session using a fixed titration schedule. ST was correlated with age, sex, body mass index, history of previous ECT, and psychotropic drugs on multiple regression analysis. Furthermore, the rate of accomplished seizures was calculated using the half-age method. Mean ST was 136 mC. ST was influenced by age, sex, history of previous ECT, and medication with benzodiazepines. The accomplished seizure rate using the half-age method was 72%, which was significantly lower in men and subjects on benzodiazepines. ST in Japanese patients was equal to or slightly higher than that previously reported in other ethnic groups, which might be attributable, at least in part, to high prevalence of and large-dose benzodiazepine prescription. Higher age, male gender, no history of ECT, and benzodiazepines were related to higher ST. The half-age method was especially useful in female patients and subjects without benzodiazepine medication. © 2014 The Authors.

    We investigated the role of family support in glycemic control by nutritional self-care behavior of Japanese patients with type 2 diabetes. One hundred twelve Japanese out-patients with type 2 diabetes were recruited for the study at Kansai Electric Power Hospital. Interviews were conducted and HbA1c and triglyceride levels were measured. HbA1c levels were significantly related to family nutritional support. Patients under 60 years old with family nutritional support showed significantly lower HbA1c than patients without family support (p1 week) showed similar outcomes in glycemic control. Patients who appreciate the support and follow the advice showed lower HbA1c (6.88 +/- 0.22%) than (7.43 +/- 0.23%) patients who appreciate the advice but sometimes feel emotional barriers. Family nutritional support is useful in improving metabolic outcome of diabetic patients. Self-care practice in disease management should be carefully adjusted to the family setting of type 2 diabetic patients. Emotional barriers to family support may affect the metabolic consequences, especially in the Japanese elderly.

    In diet therapy for diabetes, optimal energy intake and the energy distribution of macronutrients (protein : fat : carbohydrate [PFC] energy ratio) are important. We aimed to clarify the correlation between the PFC energy ratio and metabolic parameters including glycated hemoglobin A1c (HbA1c) and triglycerides in Japanese elderly patients with type 2 diabetes mellitus aged 65 years or older. Participants were 1173 diabetic patients aged 65 years or older with serum HbA1c level of >/=7.4% enrolled in the Japanese Elderly Diabetes Intervention Trial (J-EDIT). The participants were divided into four groups by the percentage of total energy intake (%E) of carbohydrate (C1: less than 55%E, C2: 55%E or more and less than 60%E, C3: 60%E or more and less than 65%E, and C4: 65%E or more). Relations of %E of carbohydrate to HbA1c and other metabolic parameters, energy intake and nutritional intake were examined. Furthermore, the subjects were divided into four categories by HbA1c levels by quartile method (Q1: less than 7.90%, Q2: 7.90% or more and less than 8.30%, Q3: 8.30% or more and less than 8.80%, Q4: 8.80% or more). Relations of HbA1c to other metabolic parameters, energy intake and nutritional intake were examined. The mean HbA1c levels in the four groups were C1: 8.40%, C2: 8.50%, C3: 8.41% and C4: 8.36% in men, and C1: 8.51%, C2: 8.47%, C3: 8.35% and C4: 8.52% in women, respectively. There were no significant differences and linear trend in HbA1c levels across groups. The mean triglyceride levels were in the range of 122-128 mg/dL in men from C1 to C3, although it was significantly higher in C4 (177 mg/dL). The mean triglyceride levels were in the range of 128-136 mg/dL in women from C1 to C3, although it was significantly higher in Q4 (150 mg/dL). Amounts of protein and fat intakes decreased with an increase of %E of carbohydrate, although amount of carbohydrate intake did not change significantly. As a result, %E of protein and fat, and energy intake decreased

    Pathogenic germline BRCA1 , BRCA2 ( BRCA1/2 ), and several other gene variants predispose women to primary ovarian, fallopian tube, and peritoneal carcinoma (OC), although variant frequency and relevance information is scarce in Japanese women with OC. Using targeted panel sequencing, we screened 230 unselected Japanese women with OC from our hospital-based cohort for pathogenic germline variants in 75 or 79 OC-associated genes. Pathogenic variants of 11 genes were identified in 41 (17.8%) women: 19 (8.3%; BRCA1 ), 8 (3.5%; BRCA2 ), 6 (2.6%; mismatch repair genes), 3 (1.3%; RAD51D ), 2 (0.9%; ATM ), 1 (0.4%; MRE11A ), 1 ( FANCC ), and 1 ( GABRA6 ). Carriers of BRCA1/2 or any other tested gene pathogenic variants were more likely to be diagnosed younger, have first or second-degree relatives with OC, and have OC classified as high-grade serous carcinoma (HGSC). After adjustment for these variables, all 3 features were independent predictive factors for pathogenic variants in any tested genes whereas only the latter two remained for variants in BRCA1/2 . Our data indicate similar variant prevalence in Japanese patients with OC and other ethnic groups and suggest that HGSC and OC family history may facilitate genetic predisposition prediction in Japanese patients with OC and referring high-risk patients for genetic counseling and testing.

    2018-01-01

    The asthma control questionnaires used in Japan are Japanese translations of those developed outside Japan, and have some limitations; a questionnaire designed to optimally evaluate asthma control levels for Japanese may be necessary. The present study was conducted to validate the Japan Asthma Control Survey (JACS) questionnaire in Japanese asthma patients. A total of 226 adult patients with mild to severe persistent asthma were enrolled and responded to the JACS questionnaire, asthma control questionnaire (ACQ), and Mini asthma quality of life questionnaire (Mini AQLQ) at Weeks 0 and 4. The reliability, validity, and sensitivity/responsiveness of the JACS questionnaire were evaluated. The intra-class correlation coefficients (ICCs) were within the range of 0.55-0.75 for all JACS scores, indicating moderate/substantial reproducibility. For internal consistency, Cronbach's alpha coefficients ranged from 0.76 to 0.92 in total and subscale scores, which were greater than the lower limit of internal consistency. As for factor validity, the cumulative contribution ratio of four main factors was 0.66. For criterion-related validity, the correlation coefficients between the JACS total score and ACQ5, ACQ6, and Mini AQLQ scores were -0.78, -0.78, and 0.77, respectively, showing a significant correlation (p asthma control status in a higher number of patients.

  14. Incidence and predictors of asymptomatic atrial fibrillation in patients older than 70 years with complete atrioventricular block and dual chamber pacemaker implantation.

    Radeljic, Vjekoslav

    2012-01-31

    AIM: To evaluate predictors of asymptomatic atrial fibrillation in patients older than 70 years with complete atrioventricular (AV) block, normal left ventricular systolic function, and implanted dual chamber (DDD) pacemaker. METHODS: Hundred and eighty six patients with complete AV block were admitted over one year to the Sisters of Mercy University Hospital. The study recruited patients older than 70 years, with no history of atrial fibrillation, heart failure, or reduced left ventricular systolic function. All the patients were implanted with the same pacemaker. Out of 103 patients who were eligible for the study, 81 (78%) were evaluated. Among those 81 (78%) were evaluated. Eighty one (78%) patients were evaluated. Follow-up time ranged from 12 to 33 months (average +\\/-standard deviation 23 +\\/- 5 months). Primary end-point was asymptomatic atrial fibrillation occurrence recorded by the pacemaker. Atrial fibrillation occurrence was defined as atrial high rate episodes (AHRE) lasting >5 minutes. Binary logistic regression was used to identify the predictors of development of asymptomatic atrial fibrillation. Results. The 81 patients were stratified into two groups depending on the presence of AHRE lasting >5 minutes (group 1 had AHRE>5 minutes and group 2 AHRE<5 minutes). AHRE lasting >5 minutes were detected in 49 (60%) patients after 3 months and in 53 (65%) patients after 18 moths. After 3 months, only hypertension (odds ratio [OR], 17.63; P = 0.020) was identified as a predictor of asymptomatic atrial fibrillation. After 18 months, hypertension (OR, 14.0; P = 0.036), P wave duration >100 ms in 12 lead ECG (OR, 16.5; P = 0.001), and intracardial atrial electrogram signal amplitude >4 mV (OR, 4.27; P = 0.045) were identified as predictors of atrial fibrillation. CONCLUSION: In our study population, hypertension was the most robust and constant predictor of asymptomatic atrial fibrillation after 3 months, while P wave duration >100 ms in 12-lead ECG and

    Full Text Available Abstract Background Late gadolinium enhancement (LGE cardiovascular magnetic resonance (CMR enables state-of-the-art in vivo evaluations of myocardial fibrosis. Although LGE patterns have been well described in asymmetrical septal hypertrophy, conflicting results have been reported regarding the characteristics of LGE in apical hypertrophic cardiomyopathy (ApHCM. This study was undertaken to determine 1 the frequency and distribution of LGE and 2 its prognostic implication in ApHCM. Methods Forty patients with asymptomatic or minimally symptomatic pure ApHCM (age, 60.2 ± 10.4 years, 31 men were prospectively enrolled. LGE images were acquired using the inversion recovery segmented spoiled-gradient echo and phase-sensitive inversion recovery sequence, and analyzed using a 17-segment model. Summing the planimetered LGE areas in all short axis slices yielded the total volume of late enhancement, which was subsequently presented as a proportion of total LV myocardium (% LGE. Results Mean maximal apical wall thickness was 17.9±2.3mm, and mean left ventricular (LV ejection fraction was 67.7 ± 8.0%. All but one patient presented with electrocardiographic negative T wave inversion in anterolateral leads, with a mean maximum negative T wave of 7.2 ± 4.7mm. Nine patients (22.5% had giant negative T waves, defined as the amplitude of ≥10mm, in electrocardiogram. LGE was detected in 130 segments of 30 patients (75.0%, occupying 4.9 ± 5.5% of LV myocardium. LGE was mainly detected at the junction between left and right ventricles in 12 (30% and at the apex in 28 (70%, although LGE-positive areas were widely distributed, and not limited to the apex. Focal LGE at the non-hypertrophic LV segments was found in some ApHCM patients, even without LGE of hypertrophied apical segments. Over the 2-year follow-up, there was no one achieving the study end-point, defined as all-cause death, sudden cardiac death and hospitalization for heart failure

    transfer, responsibility transfer, management goals, environment and handoff system. As an overall trend, Japanese nurses indicated that both information and responsibility for the patient were transferred moderately well within the hospital. They put a higher priority on the goal of patient safety......Patient handoff is a critically important process in healthcare. However, there have been few studies investigated healthcare staff perceptions of its quality and safety. In the present paper, we seek to explore essential characteristics of patient handoff. We discuss critical factors...... and strategies contributing to effective handoffs. A questionnaire survey was conducted in 2011, collecting 1462 valid responses (74% response rate) from nurses in six Japanese hospitals. There were 17 questions, each with reply options on a five-point Likert scale, covering five main aspects: information...

    2016-08-11

    INTRODUCTION The effect of asymptomatic severe aortic stenosis (ASAS) on N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels ar rest and during exercise, as well as their relevance for clinical practice remain controversial.  OBJECTIVES The aim of this study was to test the hypothesis of whether the evaluation of NT-proBNP concentrations during exercise provides additional information about the severity of aortic stenosis and left ventricular remodeling in patients with ASAS. PATIENTS AND METHODS A total of 50 patients with ASAS (mean age, 38.4 ±18.1 years) and 21 healthy subjects (mean age, 43.4 ±10.6 years) were enrolled. Rest and exercise echocardiography was performed to evaluate maximum velocity (Vmax), mean aortic gradient (AG), and aortic valve area (AVA). The left ventricular mass index (LVMI) was calculated. NT-proBNP concentrations at rest and during exercise were assessed, and the difference between the 2 values was calculated (ΔNT-proBNP). RESULTS NT-proBNP and ΔNT-proBNP levels at rest and during exercise were significantly higher in the ASAS group compared with the control group. In the ASAS group, NT-proBNP levels at rest significantly correlated with LVMI (r = 0.432; P <0.0001), AVA (r = -0.408; P <0.0001), Vmax (r = 0.375; P = 0.002), and mean AG (r = 0.257; P = 0.03). NT-proBNP levels during exercise significantly correlated with LVMI (r = 0.432; P <0.0001), mean AG (r = 0.401; P = 0.001), and AVA (r = -0.375; P = 0.001). In the multivariate logistic regression model, the factors independently associated with NT-proBNP both at rest and during exercise were age, AVA, and LVMI. CONCLUSIONS NT-proBNP levels at rest provide valuable information for identifying patients with more advanced left ventricular hypertrophy secondary to severe aortic stenosis. NT-proBNP levels during exercise do not provide new information on the severity of AS.

    The preference for dialysis modalities is not well understood in Japan. This study explored the subjective views of Japanese patients undergoing dialysis regarding their treatments. The participants were receiving in-center hemodialysis (CHD) or continuous ambulatory peritoneal dialysis (CAPD). In Study 1, 34 participants (17 CHD and 17 CAPD) were interviewed about the advantages and disadvantages of dialysis modalities. In Study 2, 454 dialysis patients (437 CHD and 17 CAPD) rated the advantages and disadvantages of CHD and CAPD in a cross-sectional survey. Interviews showed that professional care and dialysis-free days were considered as advantages of CHD, while independence, less hospital visits, and flexibility were considered as advantages of CAPD. Disadvantages of CHD included restriction of food and fluids and unpleasant symptoms after each dialysis session. Catheter care was an additional disadvantage of CAPD. Survey showed that the highly ranked advantages were professional care in CHD and less frequent hospital visits in CAPD, while the highly ranked disadvantages were concerns about emergency and time restrictions in CHD, and catheter care and difficulty in soaking in a bath in CAPD. The total scores of advantages and disadvantages showed that CHD patients subjectively rated their own modality better CHD over CAPD, while CAPD patients had the opposite opinion. The results of this study indicate that the factors affecting the decision-making process of Japanese patients are unique to Japanese culture, namely considering the trouble caused to the people around patients (e.g., families, spouses, and/or caregivers).

    ZD0473 is new platinum agent that was rationally designed to circumvent platinum resistance and reduce the potential for nephro-and neurotoxicity. This Phase I dose-escalating study investigated the pharmacokinetics, tolerability and efficacy of ZD0473 in Japanese patients with solid, refractory tumours. ZD0473 was administered as a 1-h intravenous infusion every 3 weeks. Nine patients received a total of 16 cycles of ZD0473 (median 1 cycle/patient), with 3 patients treated at each of 3 doses (60, 90, 120 mg/m2). The maximum plasma concentration (C(max)) and the area under the concentration-time curve to infinity (AUC(0-infinity)) increased with dose in a linear fashion for both total platinum and ZD0473 in plasma ultrafiltrate, suggesting that the pharmacokinetics of ZD0473 are linear. Haematological and non-haematological toxicities such as nausea and vomiting were mild (grade 1 or 2) and transient. No clinically significant nephro-, oto- or neurotoxicity was observed. Dose-limiting toxicity (DLT) was not observed and the maximum tolerated dose (MTD) was not identified. ZD0473 treatment showed evidence of disease stabilisation in 3 patients (33%). In conclusion, ZD0473 appears to have linear pharmacokinetics, and an acceptable tolerability profile at doses up to 120 mg/m2 in Japanese patients with refractory solid malignancies. Following evaluation of the data from all the Western trials, the ZD0473 development programme changed and this Japanese trial was stopped.

  1. Asymptomatic Bacteriuria and Bacterial Interference.

    Nicolle, Lindsay E

    2015-10-01

    Asymptomatic bacteriuria is very common. In healthy women, asymptomatic bacteriuria increases with age, from women age 80 years, but is uncommon in men until after age 50 years. Individuals with underlying genitourinary abnormalities, including indwelling devices, may also have a high frequency of asymptomatic bacteriuria, irrespective of age or gender. The prevalence is very high in residents of long-term-care facilities, from 25% to 50% of women and 15% to 40% of men. Escherichia coli is the most frequent organism isolated, but a wide variety of other organisms may occur. Bacteriuria may be transient or persist for a prolonged period. Pregnant women with asymptomatic bacteriuria identified in early pregnancy and who are untreated have a risk of pyelonephritis later in pregnancy of 20% to 30%. Bacteremia is frequent in bacteriuric subjects following mucosal trauma with bleeding, with 5% to 10% of patients developing severe sepsis or septic shock. These two groups with clear evidence of negative outcomes should be screened for bacteriuria and appropriately treated. Asymptomatic bacteriuria in other populations is benign and screening and treatment are not indicated. Antimicrobial treatment has no benefits but is associated with negative outcomes including reinfection with antimicrobial resistant organisms and a short-term increased frequency of symptomatic infection post-treatment. The observation of increased symptomatic infection post-treatment, however, has led to active investigation of bacterial interference as a strategy to prevent symptomatic episodes in selected high risk patients.

    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; Pbenefit in disease management of COPD in Japan. PMID:25670894

    2014-09-01

    Conclusion: Based on our results, neither Roselle tea nor cranberry juice was able to reduce the frequency of asymptomatic bacteriuria. It is inferred that cranberry juice or Roselle tea can only be used in ordinary day health care for the urinary tract.

    Usher syndrome (USH) is an autosomal recessive disorder characterized by retinitis pigmentosa and hearing loss. USH type 2 (USH2) is the most common type of USH and is frequently caused by mutations in USH2A. In a recent mutation screening of USH2A in Japanese USH2 patients, we identified 11 novel mutations in 10 patients and found the possible frequent mutation c.8559-2A>G in 4 of 10 patients. To obtain a more precise mutation spectrum, we analyzed further nine Japanese patients in this study. We identified nine mutations, of which eight were novel. This result indicates that the mutation spectrum for USH2A among Japanese patients largely differs from Caucasian, Jewish and Palestinian patients. Meanwhile, we did not find the c.8559-2A>G in this study. Haplotype analysis of the c.8559-2G (mutated) alleles using 23 single nucleotide polymorphisms surrounding the mutation revealed an identical haplotype pattern of at least 635 kb in length, strongly suggesting that the mutation originated from a common ancestor. The fact that all patients carrying c.8559-2A>G came from western Japan suggests that the mutation is mainly distributed in that area; indeed, most of the patients involved in this study came from eastern Japan, which contributed to the absence of c.8559-2A>G.

    Shiraishi, Makoto; Watanabe, Hirofumi; Sakurai, Kenzo; Kato, Bunta; Hasegawa, Yasuhiro

    2012-01-01

    Our goal was to investigate the utility of 24-hour ambulatory blood pressure monitoring (ABPM) for the risk stratification of cardiovascular events in hypertensive patients with asymptomatic or symptomatic lacunar infarcts. A total of 175 hypertensive patients with MRI evidence of asymptomatic or symptomatic lacunar infarcts (92 men, mean age of 69±11 years old) were studied. Patients with symptomatic infarctions were included whose events occurred more than 6 months after the onset. ABPM was performed in all patients in the outpatient clinic. Parameters obtained from ABPM were related to the composite outcome which consisted of all death and fatal or non-fatal cardiovascular events by using the Cox proportional hazard model. Mean follow-up period was 4.8 years and the composite outcome was recorded in 38 patients. 34 of them (89%) had recurrence of lacunar infarcts. Significant association between sleep-time lowest systolic blood pressure and composite outcome was demonstrated by multivariate Cox hazard analyses (heart rate (HR) 1.025, 95% confidence interval (CI) 1.011-1.039, p<0.001). The risk for composite outcome in patients with the highest tertile of sleep-time lowest systolic blood pressure (≥133 mmHg) was significantly elevated when compared to the lowest tertile (<132 mmHg, HR 3.93, 95% CI 1.57-9.86, p=0.004). Sleep-time lowest systolic blood pressure in ABPM may be a useful parameter for the risk stratification of future cardiovascular events in hypertensive patients with asymptomatic or symptomatic lacunar infarcts, especially for the recurrence of these events.

    The present study investigated which cognitive characteristics, including cancer phobia, self-efficacy, pain-related catastrophizing, and anxiety sensitivity, affect burning mouth syndrome (BMS) symptoms in the Japanese population. A total of 46 BMS patients (44 women and 2 men; mean age, 59.98 +/- 9.57 years; range, 30-79 years) completed a battery of questionnaires, including measures of pain severity, oral-related quality of life (QOL), stress-response, pain-related catastrophizing, self-efficacy, anxiety sensitivity, and tongue cancer phobia. The Pain Catastrophizing Scale (PCS), General Self-Efficacy Scale (GSES), and Anxiety Sensitivity Index (ASI) scores in the BMS patients were compared with the scores of Japanese healthy participants (PCS, n = 449; GSES, n = 278; ASI, n = 9603) reported in previous studies. Catastrophizing and anxiety sensitivity were significantly higher in the BMS patients than in the healthy subjects (P disability, social disability, and handicap. Cancer phobia was significantly correlated with psychological disability and handicap. Since catastrophizing showed a higher correlation with BMS symptoms than cancer phobia, catastrophizing might be a more significant cognitive factor affecting symptoms than cancer phobia in BMS patients in the Japanese population.

  10. Asymptomatic bacteriuria in pregnancy.

    Smaill, Fiona

    2007-06-01

    Screening for asymptomatic bacteriuria is a standard of obstetrical care and is included in most antenatal guidelines. There is good evidence that treatment of asymptomatic bacteriuria will decrease the incidence of pyelonephritis. All pregnant women should be screened for asymptomatic bacteriuria, and there are no new data that would indicate otherwise. Antibiotic treatment of asymptomatic bacteriuria is associated with a decrease in the incidence of preterm delivery or low birth weight, but the methodological quality of the studies means any conclusion about the strength of this association needs to be drawn cautiously. A better understanding of the mechanism by which treatment of asymptomatic bacteriuria could prevent preterm delivery is needed. While several rapid screening tests have been evaluated, none perform adequately to replace urine culture for detecting asymptomatic bacteriuria. Until there are data from well-designed trials that establish the optimal duration of therapy for asymptomatic bacteriuria, standard treatment courses are recommended.

    Objective To assess the safety of azathioprine (AZA) in Japanese patients with antineutrophil cytoplasmic antibody-associated vasculitis (AAV). Methods We retrospectively enrolled 67 consecutive AAV patients who had initiated AZA treatment from January 2006 to August 2014 at Okayama University Hospital. We evaluated the development of severe adverse events (AEs), AZA discontinuation due to total AEs (severe AEs included) within 1 year, and AZA-associated risk factors. Results The patients' median age was 70 years old. Forty-nine women and 18 men participated at the initiation of the study. Fifty-eight (87%) patients experienced AEs, and 36 experienced severe AEs (21 hepatic and 11 cytopenic severe AEs). Thirty-one (46%) patients discontinued treatment because of AEs. Abnormal hepatic laboratory test results at the treatment initiation were more frequent in patients with hepatic severe AEs and were associated with treatment discontinuation. The leukocyte and neutrophil counts at the treatment initiation were lower in the patients who discontinued treatment because of cytopenic AEs than in those who continued treatment. Only two patients experienced flare-ups during treatment. Conclusion The AE-associated AZA discontinuation rate in Japanese AAV patients was relatively high. AZA use warrants caution in patients with abnormal hepatic laboratory test results or low leukocyte or neutrophil counts. PMID:28674351

    2009-01-01

    Recently, randomized trials revealed that trastuzumab as adjuvant treatment was effective in human epidermal growth factor receptor 2 (HER2)-positive breast cancer patients. Safety information on adjuvant trastuzumab use in Japanese patients, especially cardiac toxicity data, is needed. We retrospectively reviewed 48 patients with early-stage HER2-positive breast cancer who were treated with curative surgery and adjuvant trastuzumab at the National Cancer Center Hospital East (Kashiwa, Japan). The cardiac safety as well as the short-term efficacy of trastuzumab were evaluated. The median age of the patients was 54 years. All patients received adjuvant or neoadjuvant cytotoxic chemotherapy. Twenty-seven patients (56%) received adjuvant radiation therapy. Forty-four patients (92%) received trastuzumab without concurrent cytotoxic chemotherapy and 4 patients (8%) on taxanes received trastuzumab concurrently. Twenty-five patients completed 1 year of trastuzumab treatment and 5 patients completed 2 years of trastuzumab treatment. Nine patients discontinued trastuzumab treatment, because of progressive disease (1 patient), decrease in left ventricular ejection fraction (LVEF; 2 patients), patient's refusal (4 patients), and other reasons (2 patients). There were five cardiac events. A decrease in LVEF to less than 50% was seen in 2 patients. The relationship between trastuzumab treatment and the cardiac events was unclear in 3 patients. The median follow-up time was 21.2 months. The disease-free survival (DFS) was 97.5% at 1 year and 92.9% at 2 years. The incidence of cardiac events caused by trastuzumab treatment was low in our analysis. Adjuvant trastuzumab treatment for up to at least 1 year should be safe for Japanese breast cancer patients.

    2014-01-01

    Background The present study investigated when and how Japanese people with cleft lip and palate (CL/P) learn that their condition is congenital; the perceived effects of withholding the CL/P diagnosis on patients; and whether the resulting social experience and self-esteem are related. A questionnaire survey was conducted in 71 adults with CL/P recruited through a hospital, a patients? association, and by snowball sampling. Results The participants became aware of their physical difference i...

  15. Reliability of Ultrasound Diameter Measurements in Patients with a Small Asymptomatic Popliteal Artery Aneurysm: An Intra- and Inter-observer Agreement Study.

    Zwiers, I; Hoogland, C M T; Mackaay, A J C

    2016-03-01

    In this study the intra- and inter-observer variability of ultrasound measurements of the diameter of the popliteal artery were tested in a group of patients under surveillance for a small (diameter 10-20 mm), asymptomatic popliteal artery aneurysm (PAA). From a group of patients under ultrasound surveillance for bilateral, asymptomatic PAAs, 13 consecutive patients agreed to participate in the study and provided informed consent. The maximum diameter of the popliteal arteries was assessed by a vascular technologist. The same assessment was repeated by a second vascular technologist, unaware of the results of the first measurement. After a week, this protocol was repeated. The intra- and inter-observer reliability of this measurement was calculated using intra-class correlation coefficients (ICCs) and Bland and Altman plots. Of the 10 patients with bilateral and three patients with unilateral PAA, 12 completed the 2 week protocol. A total of 86 measurements were analyzed. The mean diameter of the popliteal arteries was 13.5 ± 3.4 mm. The ICC for the intra-observer reliability of observer 1 was 0.96 (95% CI 0.92-0.99), p .47. The absolute magnitude of the systematic error of both observers was less than 0.135 mm (median 0.00). Ultrasound measurement of the maximum diameter of the popliteal artery is reproducible; hence, it is suitable for making a clinical treatment decision. Its use for surveillance of small, asymptomatic PAAs is justified. Copyright © 2015 European Society for Vascular Surgery. Published by Elsevier Ltd. All rights reserved.

    Daptomycin is a lipopeptide antibiotic active against gram-positive organisms and recently approved for marketing in Japan. This study investigates the efficacy and safety of daptomycin in Japanese patients with skin and soft tissue infections (SSTIs) caused by methicillin-resistant Staphylococcus aureus (MRSA) for regulatory filing in Japan. Overall, 111 Japanese patients with SSTI were randomized in this open-label, randomized, active-comparator controlled, parallel-group, multicenter, phase III study. Patients received intravenous daptomycin 4 mg/kg once daily or vancomycin 1 g twice daily for 7-14 days. Efficacy was determined by a blinded Efficacy Adjudication Committee. Among patients with SSTIs caused by MRSA, 81.8 % (95 % CI, 69.1-90.9) of daptomycin recipients and 84.2 % (95 % CI, 60.4-96.6) of vancomycin recipients achieved a successful clinical response at the test-of-cure (TOC) visit. The microbiological success rate against MRSA at the TOC visit was 56.4 % (95 % CI, 42.3-69.7) with daptomycin and 47.4 % (95 % CI, 24.4-71.1) with vancomycin. Daptomycin was generally well tolerated; most adverse events were of mild to moderate severity. The measurement of daptomycin concentration in plasma revealed that patients with mild or moderate impaired renal function showed similar pharmacokinetics profiles to patients with normal renal function. Clinical and microbiological responses, stratified by baseline MRSA susceptibility, suggested that patients infected with MRSA of higher daptomycin MIC showed a trend of lower clinical success with a P value of 0.052 by Cochran-Armitage test. Daptomycin was clinically and microbiologically effective for the treatment of MRSA-associated SSTIs in Japanese patients.

    This study aimed to ascertain the current status of Japanese sperm banking for young cancer patients. During 2015, we mailed the directors of 695 institutes where sperm cryopreservation might be performed with questionnaires requesting information on the number of patients, age, precryopreservation chemotherapy, semen analyses results and diagnoses, cryopreservation success rate, and causes of unsuccessful cryopreservation. Of these 695 institutes, 92 had cryopreserved sperm before chemotherapy within the study period. In all, 820 cancer patients (237 testicular, 383 hematological, 46 bone and soft tissue, 20 brain, and 134 other malignancy) consulted the responding institutes for sperm cryopreservation. Except for testicular tumor, the number of patients whose sperm was preserved before cancer treatment was low compared to that of young cancer patients. Approximately 20% of patients with malignancies other than testicular tumor underwent chemotherapy before cryopreservation. The success rate of cryopreservation in hematological malignancy was 82.5%, significantly lower than that of both the testicular cancer (93.6%) and other malignancy groups (95.6%) (P < 0.05). The primary reasons for preservation failure were azoospermia and poor semen quality. Patients with hematological malignancies had a higher rate of unsuccessful cryopreservation compared to those in other groups, possibly due to the large number of patients requesting sperm cryopreservation after chemotherapy induction. In Japan, information regarding sperm banking prior to cancer treatment appears to be lacking. Information regarding sperm preservation before chemotherapy should be provided to all Japanese oncologists.

    This study prospectively investigated the immunohistochemical expression of interleukin-2 receptor (IL-2R) and interleukin-6 (IL-6) in patients with prostate cancer and benign prostatic hyperplasia (BPH), and a possible association of these conditions with asymptomatic inflammatory prostatitis National Institutes of Health (NIH) category IV. The study included 139 consecutive patients who underwent transurethral resection of the prostate and transvesical enucleation of the prostate (n = 82) or radical prostatectomy (n = 57). To characterize inflammatory changes the criteria proposed by Irani et al. [J Urol 1997;157:1301-3] were used. IL-2R and IL-6 expression was studied by a standard immunohistochemical method. Results were correlated with tumour, node, metastasis stage, Gleason scores, total prostate-specific antigen, International Prostate Symptom Score and body mass index. IL-2R and IL-6 expression was significantly higher in neoplastic prostate cancer tissue than in normal tissue of prostate cancer patients (p Prostate cancer patients with prostatitis showed significantly higher IL-2R expression than those without inflammation (p prostatitis than in those without (p prostate cancer tissue than in normal tissue. Patients with asymptomatic inflammatory prostatitis NIH category IV showed significantly greater activity.

    Active surveillance is important in infection control programmes, allowing the detection of patients colonised with multi-drug resistant organisms and preventing the spread of multi-drug resistant organisms. The aim of this study was to determine the rate of asymptomatic colonisation with multi-drug resistant organisms and the prevalence of each organism in patients transferred to An-Najah National University Hospital, Nablus, occupied Palestinian territory. Patients transferred from other hospitals between January and December, 2015, were screened at time of admission by taking nasal, groin, and axillary swabs. Swabs were cultured and assessed for the presence of multi-drug resistant organisms (extended spectrum β-lactamase producers, Pseudomonas aeroginosae, Acinetobacter baumannii, methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococcus, and carbapenem-resistant enterobacteriaceae. Of the 822 screened patients, 265 (32%) had infections with multi-drug resistant organisms. 394 isolates of multi-drug resistant organisms were obtained: 131 (33%) isolates were extended spectrum β-lactamase producers, 119 (30%) isolates were P aeroginosae, 26 (9%) isolates were A baumannii, 94 (24%) isolates were methicillin-resistant S aureus, 13 (3%) isolates were vancomycin-resistant enterococci, and one (<1%) isolate was carbapenem-resistant enterobacteriaceae. We identified a high prevalence of asymptomatic colonisation with multidrug-resistant bacteria in transferred patients. These findings emphasise the need for a national strategy to combat the spread of multi-drug resistant organisms in the occupied Palestinian territory. An-Najah National University.

    2010-01-01

    Biomechanical stresses play an important role in determining plaque stability. Quantification of these simulated stresses can be potentially used to assess plaque vulnerability and differentiate different patient groups. 54 asymptomatic and 45 acutely symptomatic patients underwent in vivo multicontrast magnetic resonance imaging (MRI) of the carotid arteries. Plaque geometry used for finite element analysis was derived from in vivo MRI at the sites of maximum and minimum plaque burden. In total, 198 slices were used for the computational simulations. A pre-shrink technique was used to refine the simulation. Maximum principle stress at the vulnerable plaque sites (id est (ie), critical stress) was extracted for the selected slices and a comparison was performed between the 2 groups. Critical stress in the slice with maximum plaque burden is significantly higher in acutely symptomatic patients as compared to asymptomatic patients (median, inter quartile range: 198.0 kPa (119.8-359.0 kPa) vs 138.4 kPa (83.8-242.6 kPa), P=0.04). No significant difference was found in the slice with minimum plaque burden between the 2 groups (196.7 kPa (133.3-282.7 kPa) vs 182.4 kPa (117.2-310.6 kPa), P=0.82). Acutely symptomatic carotid plaques have significantly high biomechanical stresses than asymptomatic plaques. This might be potentially useful for establishing a biomechanical risk stratification criteria based on plaque burden in future studies. (author)

    In order to evaluate impulsive compulsive behaviors (ICBs), such as pathological gambling, compulsive sexual behavior, compulsive buying, compulsive eating, punding, and dopamine dysregulation syndrome (DDS) in Japanese Parkinson's disease (PD) patients, we constructed a Japanese version of the Questionnaire for Impulsive-Compulsive Disorders in Parkinson's disease (J-QUIP) and evaluated the utility of the J-QUIP in Japanese PD patients. J-QUIP was administered to 121 PD patients. Diagnoses of ICBs were made via interview of patients or their caregivers. Subsequently, in order to evaluate risk factors related to these conditions, we evaluated demographic and clinical characteristics, clinical features, and medications utilized. We were able to administer the J-QUIP to 118 of 121 PD patients (97.5%). Sensitivity and specificity of J-QUIP were similar to that reported for the original version of QUIP. In our study, the actual prevalence of each disorder diagnosed via interview was as follows: pathological gambling (6.5%), compulsive sexual behavior (3.2%), compulsive buying (3.2%), compulsive eating (3.2%), punding (6.5%), and DDS (2.2%). Significantly risk factors for these conditions were younger age (p=0.047), earlier age of disease onset (p=0.015), longer PD duration (p=0.001), total levodopa equivalent dose (p=0.006), and dosage of levodopa (p=0.019). We evaluated the prevalence of ICBs in Japanese PD patients along with factors associated with these behaviors via J-QUIP. Copyright © 2013 Elsevier B.V. All rights reserved.

    To identify prognostic factors affecting visual outcome in Acanthamoeba keratitis (AK) treated with topical chlorhexidine gluconate (CHG). A total of 35 eyes in 34 patients with AK were treated with 0.02% topical CHG. Patients were divided into two groups according to the final visual outcome: Group 1, final visual acuity (VA) of 20/25 or greater (22 eyes); Group 2, less than 20/25 (13 eyes). We compared these groups and evaluated the effectiveness of topical CHG compared with outcomes in previous reports. Ring infiltrate was observed more often in Group 2 (4.5% vs 61.5%, OR 33.6, 95% confidence interval (CI) 3.4-333.9, PAK was significantly longer (24.9 days vs 48.4 days, OR 1.03, 95% CI 1.00-1.06, P = 0.04) and VA at initial examination (log MAR) significantly lower (0.47 vs 1.59, OR 25.5, 95% CI 3.4-186.7, PAK. Topical CHG was comparably effective to other treatments, including polyhexamethyl biguanide and propamidine isethionate.

    This study evaluated the timing of carotid endarterectomy (CEA) in the prevention of stroke in patients with asymptomatic carotid stenosis >70% receiving a coronary artery bypass graft (CABG). From January 2004 to December 2009, 185 patients with unilateral asymptomatic carotid artery stenosis >70%, candidates for CABG, were randomized into two groups. In group A, 94 patients received a CABG with previous or simultaneous CEA. In group B, 91 patients underwent CABG, followed by CEA. All patients underwent preoperative helical computed tomography scans, excluding significant atheroma of the ascending aorta or aortic arch. Baseline characteristics of the patients, type of coronary artery lesion, and preoperative myocardial function were comparable in the two groups. In group A, all patients underwent CEA under general anesthesia with the systematic use of a carotid shunt, and 79 patients had a combined procedure and 15 underwent CEA a few days before CABG. In group B, all patients underwent CEA, 1 to 3 months after CABG, also under general anesthesia and with systematic carotid shunting. Two patients (one in each group) died of cardiac failure in the postoperative period. Operative mortality was 1.0% in group A and 1.1% in group B (P = .98). No strokes occurred in group A vs seven ipsilateral ischemic strokes in group B, including three immediate postoperative strokes and four late strokes, at 39, 50, 58, and 66 days, after CABG. These late strokes occurred in patients for whom CEA was further delayed due to an incomplete sternal wound healing or because of completion of a cardiac rehabilitation program. The 90-day stroke and death rate was 1.0% (one of 94) in group A and 8.8% (eight of 91) in group B (odds ratio [OR], 0.11; 95% confidence interval [CI], 0.01-0.91; P = .02). Logistic regression analysis showed that only delayed CEA (OR, 14.2; 95% CI, 1.32-152.0; P = .03) and duration of cardiopulmonary bypass (OR, 1.06; 95% CI, 1.02-1.11; P = .004) reliably predicted

    Differing survival rates have been reported between patients having undergone surgical intervention for the treatment of gastric carcinoma in Japan and Western industrialized countries. Through the actual availability of the data compiled at a major Japanese medical center (National Cancer Center, Tokyo), it was possible, for the first time, to compare the patients and therapeutic results of a Japanese center (n = 1475) with that of a German center (Department of Surgery, Technical University of Munich, Munich; n = 453). The prognostic factors involving both groups were compared. Survival rates were analyzed in univariate and multivariate fashions. Some of the examined prognostic factors, such as sex, histologic type, tumor size, and Borrmann classification, were similarly distributed. Differences in frequency were discovered concerning pathologic tumor (pT), node (pN), and metastasis (pM) categories, localization, and age groups. Univariate analysis showed a 2-year survival rate of 88% for all Japanese patients with gastric cancer compared with 58% for German patients. The 5-year survival rates were 77% and 44%, respectively. The difference in the 2-year and 5-year survival rates for both departments may be related to differences in frequencies of several characteristics. In performing the same analysis in a multivariate fashion for the patient populations at both centers, it became clear that an important prognostic factor was the center itself. The survival curves of patients from Tokyo and Munich with the same prognostic factors demonstrate this difference. These differences, however, were small in comparison with those of univariate analysis. Using a similar classification of the tumor stage and similar prognostic characteristics, the prognosis for gastric cancer in Japan and Germany may be the same.

    To determine the prevalence of asymptomatic cryptococcal antigen (CRAG) using lateral flow assay (LFA) in hospitalised HIV-infected patients with CD4 counts 18 years old without prior cryptococcal meningitis, without clinical suspicion of cryptococcal meningitis, regardless of antiretroviral (ART) status, and with CD4 counts <200 cells/μl. Serum CRAG was tested by LFA in all patients, and whole blood CRAG was tested by LFA in positive cases. We enrolled 163 participants of whom 61% were men. The duration of HIV diagnosis was a median of 8 (range, 1-29) years. 26% were antiretroviral (ART)-naïve, and 74% were ART-experienced. The median CD4 cell count was 25 (range, 1-192) cells/μl. Five patients (3.1%; 95%CI, 1.0-7.0%) were asymptomatic CRAG-positive. Positive results cases were cross-verified by performing LFA in whole blood. 3.1% of HIV-infected inpatients with CD4 <200 cells/μl without symptomatic meningitis had cryptococcal antigenemia in São Paulo, suggesting that routine CRAG screening may be beneficial in similar settings in South America. Our study reveals another targeted population for CRAG screening: hospitalised HIV-infected patients with CD4 <200 cells/μl, regardless of ART status. Whole blood CRAG LFA screening seems to be a simple strategy to prevention of symptomatic meningitis. © 2016 John Wiley & Sons Ltd.

    Decreased circulating endothelial progenitor cells (EPCs) are considered as strong and robust biomarkers for the prediction of cardiovascular outcomes in diabetic populations. The perspectives for modulating EPCs levels in T2DM with known coronary artery disease (CAD) with different drugs, affected mechanisms of improving mobilization of EPCs from tissue, are not still understood. To evaluate an effect of angiotensin-2 receptor blocker valsartan on circulating level of EPCs in diabetic patients with asymptomatic CAD. The study population was structured retrospectively after determining the CAD by contrast-enhanced spiral computed tomography angiography in 126 asymptomatic subjects. All subjects were distributed into two cohorts depending on daily doses of valsartan given. Low (80-160 mg daily orally) and high doses (240-320 mg daily orally) of valsartan were used and they were adjusted depending on achieving BP level less than 140/80 mmHg. The change from baseline in CD34(+) subset cells (frequencies and absolute values) was not significantly different between treatment cohorts. We found a significant increase of circulating level of CD14(+)CD309(+) cells in two patient cohorts. But more prominent change of CD14(+)CD309(+) cells was verified in subjects who were given valsartan in high daily doses when compared with persons who were included into cohort with low daily doses of the drug (1.96% versus 2.59%, respectively; Pvalsartan only. We found positive influence of angiotensin-2 receptor blocker valsartan in escalation doses on bone marrow-derived EPCs phenotyped as CD14(+)CD309(+) and CD14(+)CD309(+)Tie(2+) in T2DM patients with known asymptomatic CAD.

    A solitary fibrous tumour is a rare, mainly benign spindle cell mesenchymal tumour most commonly originating from the pleura. An intrapericardial location of a solitary fibrous tumour is extremely unusual. We present a case of an asymptomatic patient with a slow-growing massive benign cardiac solitary fibrous tumour. A 37-year-old asymptomatic female patient was referred to our hospital with an enlarged cardiac silhouette found on her screening chest X-ray. The echocardiographic examination revealed pericardial effusion and an inhomogeneous mobile mass located in the pericardial sac around the left ventricle. Cardiac magnetic resonance (MRI) examination showed an intrapericardial, semilunar-shaped mass attached to the pulmonary trunk with an intermediate signal intensity on proton density-weighted images and high signal intensity on T2-weighted spectral fat saturation inversion recovery images. First-pass perfusion and early and late gadolinium-enhanced images showed a vascularized mass with septated, patchy, inhomogeneous late enhancement. Coronary computed tomography angiography revealed no invasion of the coronaries. Based on the retrospectively analysed screening chest X-rays, the mass had started to form at least 7 years earlier. Complete resection of the tumour with partial resection of the pulmonary trunk was performed. Histological evaluation of the septated, cystic mass revealed tumour cells forming an irregular patternless pattern; immunohistochemically, the cells tested positive for vimentin, CD34, CD99 and STAT6 but negative for keratin (AE1-AE3), CD31 and S100. Thus, the diagnosis of an intrapericardial solitary fibrous tumour was established. There has been no recurrence for 3 years based on the regular MRI follow-up. Intrapericardial SFTs, showing slow growth dynamics, can present with massive extent even in completely asymptomatic patients. MRI is exceedingly useful for characterizing intrapericardial masses, allowing precise surgical planning, and

    In this phase I dose-escalation study we evaluated the safety, tolerability, pharmacokinetics, and antitumor activity of ibrutinib, an oral covalent inhibitor of Bruton's tyrosine kinase (BTK, in Japanese patients with relapsed/refractory B cell malignancies (RRBCM). Fifteen patients aged 42-78 years were enrolled to one of three cohorts. Cohort 1 (n = 3) consisted of two phases, a single-dose (140 and 280 mg) phase and a multiple-dose (420 mg) phase of ibrutinib; cohort 2 (n = 6) included multiple doses of ibrutinib 560 mg; and cohort 3 (n = 6) included only patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) dosed at ibrutinib 420 mg. One patient (CLL/SLL cohort) experienced grade 3 pneumonia and sepsis, which were considered dose-limiting toxicities. No deaths were reported. The most common (≥ 20% patients) adverse events were neutropenia, anemia, nasopharyngitis, increased bilirubin, and rash. Dose-dependent increase in maximum plasma concentration and area under the concentration from 0 to the last quantifiable time was observed, while time to reach maximum plasma concentration and elimination half-life was similar between doses. The overall response rate was 73.3% (11/15) for all cohorts combined. Overall, ibrutinib (420 and 560 mg) was tolerable with acceptable safety profiles and effective for Japanese patients with RRBCM including CLL/SLL. NCT01704963.

  10. Asymptomatic aortic stenosis: An assessment of patients' and of their general practitioners' knowledge, after an indexed specialized assessment in community practice.

    Raphaëlle-Ashley Guerbaii

    Full Text Available Clinical and echocardiography follow-up is recommended in patients with aortic stenosis to detect symptom onset, thus a watchful waiting approach has to be safe and effective. For both AS patients and their general practitioners, evaluation of valvular heart disease (VHD knowledge, after the indexed specialized assessment has never been measured.To evaluate the knowledge of clinical symptoms of aortic stenosis by both patients and their general practitioner.Sixty-four patients, with moderate to severe and initially asymptomatic AS (median AVA (interquartile range 1.01(0.80-1.15 cm2 previously referred to a tertiary center and medically managed for at least 6 months after the index echocardiogram, and their primary care doctors were interviewed on the phone and asked to answer specific questions related to knowledge of aortic stenosis symptoms.Fifty-six percent of patients quoted shortness of breath as one of the aortic stenosis symptoms, and only 16% knew the 3 aortic stenosis symptoms. Fifty percent of patients reported having received sufficient information regarding aortic stenosis; only 48% remembered receiving information regarding specific symptoms. Only 14% general practitioners quoted the 3 specific symptoms. According to the initial recommendation, only 41 patients (64% benefitted from a 6-to-12 month clinical and echocardiography follow up.GPs are not sufficiently trained to safely manage AS patients in the community and to ensure adequate follow-up and monitoring. AS patients were not properly informed about their diagnosis and symptomatology. Hence, therapeutic education should be improved for patients with asymptomatic AS and continuous medical education on VHD should be reinforced, for GPs.

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

    The aims of this survey was to provide insight into treatment activity, the strategy of treatment, and risk stratification of patients with asymptomatic and symptomatic ventricular pre-excitation across Europe. Fifty-eight centres, members of the European Heart Rhythm Association EP research network, covering 20 countries answered the survey questions. All centres were high-volume ablation centres. A younger person with asymptomatic Wolff-Parkinson-White (WPW) pattern has a higher likelihood of being risk-stratified or receiving ablation therapy compared with an older subject. Two-thirds of centres report that they have observed a decline in the number of patients ablated for an accessory pathway during the last 10 years. Pre-excited atrial fibrillation is rarely seen. Discontinuation of a scheduled WPW ablation due to close vicinity of the accessory pathway to the AV node happens very rarely. Patients with a first episode of pre-excited atrial fibrillation would immediately be referred for catheter ablation to be performed within weeks by 80.4% of the centres. A significant proportion of responders (50.9%) would use electrical cardioversion to restore sinus rhythm in a patient with pre-excited atrial fibrillation. With respect to the choice of antiarrhythmic medication for a patient with pre-excited AF, the majority (80.0%) would choose class 1C antiarrhytmic drugs while waiting for a catheter ablation. A patient seen in the emergency room with a second episode of orthodromic atrioventricular reentry tachycardia would be referred for immediate ablation by 79.2-90.6% of centres depending on the presence of pre-excitation. The volume of paediatric ablations performed on children younger than 12 years was low (46.4%: 0 patients per year; 46.4%: 1-9 patients per year). The majority of responding centres (61-69%) report that their country lack national guidelines dealing with clinical strategies related to WPW. There is a need for national guidelines dealing with

    The Oxford Classification is utilized globally, but has not been fully validated. In this study, we conducted a comparative analysis between the Oxford Classification and Japanese Histologic Classification (JHC) to predict renal outcome in Japanese patients with IgA nephropathy (IgAN). A retrospective cohort study including 86 adult IgAN patients was conducted. The Oxford Classification and the JHC were evaluated by 7 independent specialists. The JHC, MEST score in the Oxford Classification, and crescents were analyzed in association with renal outcome, defined as a 50% increase in serum creatinine. In multivariate analysis without the JHC, only the T score was significantly associated with renal outcome. While, a significant association was revealed only in the JHC on multivariate analysis with JHC. The JHC and T score in the Oxford Classification were associated with renal outcome among Japanese patients with IgAN. Superiority of the JHC as a predictive index should be validated with larger study population and cohort studies in different ethnicities.

    Full text: The purpose of this study was to compare the accuracy of this new technique against the accepted ''gold standard'' of contrast venography in 36 asymptomatic high risk patients. A kit formulation has been devised in which 99m Tc is labelled to rt- PA where the plasminogen binding site has been permanently inhibited but the fibrin binding site remained active. Kit preparation prior to injection takes five minutes. Scintigraphic imaging is performed at four hours post-injection (10 min/scan for thighs and calves). The results of scintigraphic imaging were then compared to those of contrast venography. 36 consecutive asymptomatic high risk patients (17 total hip, 19 total knee replacements) underwent both a contrast venogram on the operated leg and scintigraphic scan 7-10 days following operation. For the purpose of this analysis, each venogram was divided into a proximal and a distal segment. Venograms were interpreted as being positive, negative or uninterpretable in each segment. Similar analysis of the scintigraphic scans was performed except that all segments were considered to be of diagnostic quality. Fifty seven segments were able to be analysed. Of the 13 thrombosed segments (1 proximal, 12 calf ), 12 had positive scans; in the 44 non-thrombosed segments, 40 had negative scans. In detecting lower limb DVT, scanning had a sensitivity of 92% and a specificity of 91%. Scintigraphic scanning with inhibited 99m Tc rt-PA permits accurate detection of thrombus in high risk patients

    To compare electromyographic activity in patients with symptomatic rotator cuff tears with healthy controls or to those with asymptomatic cuff tears. TYPE: Systematic review and meta-analysis. PubMed, Scopus, Ovid Medline, and Web of Science were searched from inception to August 1, 2014, and a search update was performed on June 8, 2015. Case-control studies or intervention studies that had baseline comparisons for symptomatic versus healthy shoulders or those with asymptomatic rotator cuff tear were searched. Methodological quality was assessed with a modified Critical Appraisal Skills Programme score and meta-analyses were performed when 2 or more studies explored the same outcome measures. Nine studies were included, with the quality ranging from 1 to 3 (maximum 6). Electromyographic outcomes included amplitudes and ratios thereof, activity duration, and median frequency of shoulder girdle muscles during isometric contractions (4 studies) and functional tasks (5 studies). Longer activity duration was found for upper trapezius during glenohumeral movements, and greater fatigability of anterior and middle deltoids during isometric hand gripping for patients with rotator cuff tears compared to controls. The meta-analysis (3 studies) showed that patients with rotator cuff tears had lower activation ratios for latissimus dorsi during isometric abduction contraction compared to controls (P muscle activity differences between the rotator cuff tear group and controls is thus limited.

    Personality traits were assessed by means of the Munich Personality Test (MPT) in 75 Japanese subjects, 27 patients in remission from an episode of moderate to severe primary unipolar depression, with melancholic features during one episode or more of the disorder, in 24 patients in remission from other non-organic mental disorders and in 24 healthy controls. Compared with healthy controls, unipolar depressives displayed decreased Frustration Tolerance and elevated Rigidity as well as a stronger Orientation towards Social Norms. No significant difference was found between patients in remission from either unipolar depression or other mental disorders. However, the increase in Rigidity in comparison with healthy subjects was significant in the depressives only whereas the other patients, in contrast to the depressives, had significantly lower scores in Extraversion than the healthy subjects. Our results in Japanese patients are similar to findings of previous German studies, including two high risk studies, in which the same assessment instrument was used. This suggests that, beyond cultural differences, Rigidity, possibly in combination with a strong Orientation towards Social Norms and a reduced Frustration Tolerance, is a stable vulnerability marker for at least the more severe forms of primary unipolar depression.

    Although the definitive risk factors for parastomal hernia development remain unclear, potential contributing factors have been reported from Western countries. The aim of this study was to identify the risk factors for parastomal hernia in Japanese patients with permanent colostomies. All patients who received abdominoperineal resection or total pelvic exenteration at our institution between December 2004 and December 2011 were reviewed. Patient-related, operation-related and postoperative variables were evaluated, in both univariate and multivariate analyses, to identify the risk factors for parastomal hernia formation. Of the 80 patients who underwent colostomy, 22 (27.5 %) developed a parastomal hernia during a median follow-up period of 953 days (range 15-2792 days). Hernia development was significantly associated with increasing patient age and body mass index, a laparoscopic surgical approach and the transperitoneal route of colostomy formation. In the multivariate analysis, the body mass index (p = 0.022), the laparoscopic approach (p = 0.043) and transperitoneal stoma creation (p = 0.021) retained statistical significance. Our findings in Japanese ostomates match those from Western countries: a higher body mass index, the use of a laparoscopic approach and a transperitoneal colostomy are significant independent risk factors for parastomal hernia formation. The precise role of the stoma creation route remains unclear.

  20. Group cognitive behavior therapy for Japanese patients with social anxiety disorder: preliminary outcomes and their predictors

    2007-12-01

    Full Text Available Abstract Background A number of studies have provided strong evidence for the use of cognitive behavior therapy (CBT in the treatment of social anxiety disorder (SAD. However, all of the previous reports were from Europe and North America and it is unknown whether Western psychological therapies are effective for SAD in non-Western cultures. The present pilot study aimed to evaluate CBT program for SAD which was originally developed for Western patients, among Japanese patients. Methods Fifty-seven outpatients who participated in group CBT for SAD were evaluated using eight self-reported and one clinician-administered questionnaires to measure various aspects of SAD symptomatology at the beginning and at the end of the program. Pre- and post-treatment scores were compared and the magnitude of treatment effect was quantified as well based once on the intention-to-treat (ITT and once among the completers only. We also examined baseline predictors of the CBT outcomes. Results Seven patients (12% did not complete the program. For the ITT sample, the percentage of reduction was 20% to 30% and the pre to post treatment effect sizes ranged from 0.37 to 1.01. Among the completers, the respective figures were 20% to 33% and 0.41 to 1.19. We found no significant pretreatment predictor of the outcomes. Conclusion Group CBT for SAD is acceptable and can bring about a similar degree of symptom reduction among Japanese patients with SAD as among Western patients.

    We evaluated neuropsychological function, magnetic resonance (MR) images and cerebral blood flow (CBF) in patients with unruptured asymptomatic cerebral aneurysms. Among consecutive operations (n=73) on 70 patients since 2000, direct surgery was performed in 53 operations on 50 patients, and intravascular surgery was performed in 20 operations on 20 patients. Surgical results of direct surgery were studied. Direct surgery was selected mainly for patients with small and anterior circulation aneurysms. MR imaging was conducted 1 week after surgery, and Wechsler Adult Intelligence Scale-Revised (WAIS-R) examination and CBF measurement using 133 Xe-SPECT were done before and 1 month after surgery. Abnormal neurological findings were recognized postoperatively in 26% of surgeries. Among them, visual disturbance was permanent in 4% of surgeries, all of which were surgeries for paraclinoid internal carotid artery aneurysms. WAIS-R results deteriorated in 26% of surgeries at 1 month and at least in 5% of surgeries at 1 year after surgery. MR images at 1 week after surgery revealed brain damage in 30% of surgeries and subdural fluid collection in 19% of surgeries. Patients with large brain damage or thick subdural fluid collection frequently showed neurological deficits and/or WAISR deterioration. These complications were recognized frequently in patients with ACoA aneurysms. Resting CBF decreased significantly in the area supplied by the anterior cerebral artery and anterior border zone on the operated side postoperatively. The brain damage and subdural fluid collection were observed frequently and caused neurological deficits and neuropsychological dysfunction, although these were usually transient. It may be necessary to evaluate neuropsychological function, MRI and CBF in patients with unruptured asymptomatic cerebral aneurysms to improve surgical results. (author)

    The pathophysiological mechanisms responsible for the disparity in stroke risk between asymptomatic and symptomatic carotid stenosis patients are not fully understood. The functionally important reticulated platelet fraction and reticulocytes could play a role. We performed a prospective, multi-centre, observational analytical study comparing full blood count parameters and platelet production/turnover/activation markers in patients with asymptomatic versus recently symptomatic moderate (≥ 50-69%) or severe (≥ 70-99%) carotid stenosis. Data from 34 asymptomatic patients were compared with 43 symptomatic patients in the 'early phase' (≤ 4 weeks) and 37 of these patients in the 'late phase' (≥ 3 months) after TIA/ischaemic stroke. Reticulated platelets were quantified by whole blood flow cytometry and reticulated platelets and red cell reticulocytes by 'automated assays' (Sysmex XE-2100™). Bilateral simultaneous transcranial Doppler ultrasound monitoring classified patients as micro-embolic signal (MES)+ve or MES-ve. Mean platelet count was higher in early (216 × 10 9 /L; P = 0.04) and late symptomatic (219 × 10 9 /L; P = 0.044) than asymptomatic patients (194 × 10 9 /L). Mean platelet volume was higher in early symptomatic than asymptomatic patients (10.8 vs. 10.45 fl; P = 0.045). Automated assays revealed higher % reticulated platelet fractions in early (5.78%; P < 0.001) and late symptomatic (5.11%; P = 0.01) than asymptomatic patients (3.48%). Red cell reticulocyte counts were lower in early (0.92%; P = 0.035) and late symptomatic (0.93%; P = 0.036) than asymptomatic patients (1.07%). The automated % reticulated platelet fraction was also higher in early symptomatic than asymptomatic MES-ve patients (5.7 vs. 3.55%; P = 0.001). The combination of increased platelet counts and a shift towards production of an increased population of larger, young, reticulated platelets could contribute to a higher risk of first or recurrent

    Atrial fibrillation (AF) is the most common cardiac arrhythmia, with increasing prevalence in Japan. Although prothrombin time-international normalized ratio (PT-INR) targets for monitoring warfarin therapy in patients with nonvalvular AF (NVAF) are well defined, real-world patient characteristics and PT-INR levels remain unknown among Japanese patients with NVAF who initiate and continue warfarin (warfarin maintainers) versus those who switch from warfarin to direct oral anticoagulants (DOACs; warfarin switchers). Patients with NVAF receiving oral anticoagulants between February 2013 and June 2015 were identified using a nationwide electronic medical record (EMR) database from 69 hospitals in Japan. Demographics and characteristics of patients, PT-INR, time in therapeutic range (TTR), and frequency in range (FIR) of PT-INR between warfarin maintainers and warfarin switchers were assessed. A total of 1705 patients met inclusion criteria and were examined (1501 warfarin maintainers versus 204 warfarin switchers). CHADS 2 , CHA 2 DS 2 -VASc, and HAS-BLED scores were comparable between groups. However, these scores were significantly higher among warfarin switchers at the time of switching than at the time of warfarin initiation. Furthermore, TTR and FIR of PT-INR were lower in warfarin switchers than in maintainers. Nevertheless, TTR and FIR were below 50% (PT-INR, 1.6-2.6) in both patient groups. In this EMR-based clinical study, patients who switched to DOACs had both poor or inadequate PT-INR control and higher risk factors of stroke. Many patients receiving warfarin did not achieve sufficient PT-INR therapeutic range. DOACs could be recommended in Japanese patients with NVAF with inadequate PT-INR control and increased risk of stroke. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

    Full Text Available Introduction and objective: asymptomatic hypertransaminasemia (AH is a common finding in clinical practice. We propose to determine the prevalence of AH in our environment, its epidemiology and its evolution. Material and methods: we studied a random sample of 1,136 blood tests undertaken in 2006, excluding patients with known hepatic disease or symptoms or signs of liver disease, and following the evolution of the AHs until 2009. Data was analyzed using bivariate and multivariate logistic regression. Results: the percentage of patients found with a AH was 15.24% (95% CI 13.52 to 16.96%. The rates of AST and ALT, were 6.93% (95% CI 5.71 to 8.15% and 14.31% (95% CI 12.65 to 15.97% respectively. The percentage of normalization of transaminase values in a second analytical control was a 31.81% (95% CI: 26.21 to 37.4%. An association was found between AH and BMI (OR: 1.129, 95% CI 1.062 to 1.199 and between the persistence of AH and GGT (OR: 1.011, 95% CI 1.003 to 1.018. Fundamental tests such as hepatitis serology or ultrasound were performed on only 50% of patients (with 32% of steatohepatitis. Conclusions: the prevalence found in our study of AH was relatively high (15.24%, being more frequently encountered in obese subjects. Nearly a third of the AHs is normalized in a subsequent blood test. The high GGT is associated with persistence of AH. There is great variability in terms of additional testing in patients with AH and the application of such tests is not protocol.Introducción y objetivo: la hipertransaminasemia asintomática (HA es un hallazgo frecuente en la práctica clínica diaria.

    To evaluate the clinical benefit of pancreaticoduodenectomy in a Japanese fashion for patients with pancreatic head cancer. One hundred and one patients underwent pancreatectomy for pancreatic head cancer between 1980 and 2001. Of these, 40 patients in the extended resection (ER) group had an extended lymphadenectomy and neural plexus dissection as a Japanese fashion, while 61 patients in the conventional resection (CR) group. Tumor status, morbidity, mortality, survival and pattern of recurrence were retrospectively studied. The incidence of R0 operations in the ER group was higher than that in the CR group (pJapanese fashion with an adequate extended resection might bring a survival benefit for patients with pStage IIA or IIB pancreatic head cancer.

    In this single-blind, parallel, placebo-controlled study, the pharmacokinetics, pharmacodynamics, tolerability, and safety of subcutaneous exenatide were evaluated in 40 Japanese patients with type 2 diabetes. Patients were allocated to 4 groups and randomized to receive exenatide (n = 8/group) or placebo (n = 2/group), with all receiving placebo on day 1. On day 2, patients received single-dose exenatide (2.5 microg [group A] or 5 microg [groups B, C, and D]) or placebo and then bid on days 3 to 5. On days 6 to 10, groups A and B continued on 2.5 and 5 microg bid; groups C and D received 10 and 15 microg bid, respectively. The last dose was given on the morning of day 10. All adverse events were mild or moderate in severity. Exenatide was generally well tolerated up to 10 microg. Exenatide was well absorbed with a median t(max) of 1.5 hours and mean t((1/2)) of 1.6 hours; exposure increased with dose. Up to 10 microg, exenatide reduced postprandial glucose concentrations in a dose-dependent fashion compared with placebo; decreases were similar for 10 and 15 microg. An E(max) model demonstrated that doses higher than 2.5 microg were necessary for adequate glycemic response. Based on tolerability and pharmacokinetic/pharmacodynamic relationships, 5 and 10 microg exenatide may be considered for further clinical development in Japanese patients with type 2 diabetes.

    Diabetic patients with chronic kidney disease (CKD) frequently develop cardiac events within several years of the initiation of haemodialysis. The present study assesses the prognostic significance of stress myocardial ECG-gated perfusion imaging (MPI) in patients with diabetic CKD requiring haemodialysis. Fifty-five asymptomatic patients with diabetic stage V CKD and no history of heart disease scheduled to start haemodialysis were enrolled in this study (56{+-}11 years old; 49 with type 2 diabetes mellitus). All patients underwent {sup 201}Tl stress ECG-gated MPI 1 month before or after the initiation of haemodialysis to assess myocardial involvement. We evaluated SPECT images using 17-segment defect scores graded on a 5-point scale, summed stress score (SSS) and summed difference scores (SDS). The patients were followed up for at least 2 years (42{+-}15 months) to determine coronary intervention (CI) and heart failure (HF) as soft events and acute myocardial infarction (AMI) and all causes of deaths as hard events. The frequencies of myocardial ischaemia, resting perfusion defects, low ejection fraction and left ventricular (LV) dilatation were 24,20,29 and 49%, respectively. Ten events (18%) developed during the follow-up period including four CI, one HF, one AMI and four sudden deaths. Multivariate Cox analysis selected SDS (p=0.0011) and haemoglobin A{sub 1c} (HbA{sub 1c}) (p=0.0076) as independent prognostic indicators for all events. Myocardial ischaemia, in addition to glycaemic control, is a strong prognostic marker for asymptomatic patients with diabetic CKD who are scheduled to start haemodialysis. Stress MPI is highly recommended for the management and therapeutic stratification of such patients. (orig.)

    Full Text Available 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 χ2 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.

    The purpose of this study was to examine by proton spectroscopy for any difference in cerebral metabolites in patients taking part in the Concorde study (comparing the efficacy of immediate versus deferred treatment with zidovudine on asymptomatic HIV infected individuals). Forty seven HIV positive male patients [29 immediate, 18 deferred zidovudine] were examined in the last 9 months of the therapeutic trial. Magnetic resonance imaging and proton spectroscopy were performed at 1.5 Tesla using a single voxel placed in the parieto-occipital white matter. No significant difference was found in metabolite ratios comparing immediate versus deferred zidovudine (NA/NA+Cho+Cr 0.52 vs. 0.52). High quality spectra were acquired in relatively large numbers of patients and logistically spectroscopy may be applied to clinical therapeutic studies.

    2013-01-01

    The authors report an unusual case of Rocky Mountain spotted fever that presented as an asymptomatic petechial eruption on the lower legs. Rocky Mountain spotted fever is rare in New England and, as such, is typically not on the differential diagnosis when presented with such patients. What began as an asymptomatic eruption progressed to more classic signs of the disease, including a positive Rocky Mountain spotted fever titer. The patient was successfully treated with doxycydine and within a...

    2018-06-01

    To determine the cost of depression comorbidity among Japanese adults with rheumatoid arthritis (RA). A retrospective database study of 8968 patients diagnosed with RA between 2010 and 2015 and treated with any RA medication was conducted. Health care utilization characteristics were compared between patients with and without a comorbidity of depression. Propensity score matching was applied to ensure a balanced comparison between the two cohorts. The prevalence of a depression comorbidity was found for 5% of the total RA patients. This comorbidity was associated with 62% (56%) higher total outpatient visits and 66% (163%) higher rate of emergency room visits after 6 (12) months. Burden of depression among RA patients in Japan is relatively high and awareness for depression as a comorbidity of RA needs to be reinforced. Janssen Pharmaceutical KK.

    1999-01-01

    Purpose: to report the results of a prospective randomized study concerning the role of radiotherapy in the treatment of stage III, unresectable, asymptomatic non-small cell lung cancer. Material and methods: between 1992 and 1996, 240 patients with stage III, unresectable, asymptomatic non-small cell lung cancer were enrolled in this study, and sequentially randomized to one of the three treatment arms: conventional irradiation, hypo-fractionated irradiation and control group. In the conventional irradiation arm (79 patients), a dose of 50 Gy in 25 fractions in five weeks was delivered to the primary tumor and the mediastinum. In the hypo-fractionated irradiation arm (81 patients), there were two courses of irradiation separated by an interval of four weeks. In each series, patients received 20 Gy in five fractions in five days, in the same treatment volume as the conventional irradiation group. in the control group arm, 80 patients initially did not receive radiotherapy and were only observed. Delayed palliative hypo-fractionated irradiation (20-25 Gy in four to five fractions in four to five days) was given to the primary tumor when major symptoms developed. Results: the two-year actuarial survival rates for patients in the conventional irradiation, hypo-fractionated irradiation and control group arms were 18%, 6% and 0%, with a median survival time of 12 months, nine months and six months respectively. The differences between survival rates were statistically significant at the 0.05 level. Conclusion: although irradiation provides good palliation the results are disappointing. The comparison of conventional and hypo-fractionated irradiation shows an advantage for conventional schedules. (author)

  15. Cerebrospinal fluid HIV-1 RNA levels in asymptomatic patients with early stage chronic HIV-1 infection: support for the hypothesis of local virus replication.

    1999-08-20

    To assess HIV-1 RNA levels in cerebrospinal fluid (CSF) and their potential correlation with plasma viral load and central nervous system (CNS) HIV-1 infection markers in stable asymptomatic patients with a CD4 T cell count >500x10(6) cells/l. Consecutive patients screened for two trials were eligible for lumbar puncture assessment. At day 0, simultaneous samples of CSF and plasma were obtained and levels of total proteins, albumin, IgG, antibodies against HIV-1 p24 antigen, HIV-1 RNA (using the polymerase chain technique) and white cells were measured. The integrity of the blood-brain barrier was preserved (albumin index > or =7) in 59 out of 70 patients (84%). Intrathecal production of antibodies against HIV-1 p24 antigen was demonstrated in 55 out of 70 individuals (78%). Viral load in CSF was significantly lower than plasma values (3.13+/-0.95 versus 4.53+/-0.53, P = 0.0001). HIV-1 RNA was not detected in CSF in only three of the 70 patients (4%). Overall, there was a significant correlation between plasma and CSF HIV-1 RNA levels (r = 0.43, P = 0.0001); however, in 29 patients (41%) there were significant differences (>1.5 log10 copies/ml) between the viral loads in plasma and CSF. In the multivariate analysis, a high level of protein and white cells in CSF, but not the HIV-1 RNA plasma level, were factors independently associated with a higher level of HIV-1 RNA in CSF (P = 0.0001). HIV-1 RNA can be detected almost always in CSF of asymptomatic patients in early stages of HIV-1 infection including those with a preserved integrity of the blood-brain barrier. The important discrepancies between plasma and CSF viral load, and the independent association between CSF abnormalities and CSF viral load, support the hypothesis of local production of HIV-1.

    Complications of adult spinal deformity surgery are problematic in osteoporotic individuals. We compared outcomes between Japanese patients treated perioperatively with teriparatide vs. low-dose bisphosphonates. Fifty-eight osteoporotic adult Japanese female patients were enrolled and assigned to perioperative teriparatide (33 patients) and bisphosphonate (25 patients) groups in non-blinded fashion. Pre- and post-operative X-ray and computed tomography imaging were used to assess outcome, and rates were compared between the groups and according to age. Pain scores and Oswestry Disability Indices (ODI) were calculated before and 2 years after surgery. Adjacent vertebral fractures and implant failure, fusion failure, and poor pain and ODI outcomes were significantly more common in the bisphosphonates group than the teriparatide group. Perioperative administration of teriparatide is more effective than that of low-dose bisphosphonates in preventing complications and maintaining fusion rates in osteoporotic Japanese females with spinal deformities undergoing surgery.

    2018-03-01

    This study examined the clinical significance of N-terminal pro brain natriuretic peptide level as a cardiac marker in Japanese hemodialysis patients. This was a multicenter cross-sectional study involving 1428 Japanese hemodialysis patients. Ultrasonic cardiography data at post-hemodialysis were obtained from 395 patients. We examined whether serum N-terminal pro brain natriuretic peptide levels were associated with cardiac parameters and assessed cut-off values and investigated factors associated with a reduced ratio of N-terminal pro brain natriuretic peptide levels pre- and post-hemodialysis. Multivariate logistic regression analysis showed that pre- and post-hemodialysis N-terminal pro brain natriuretic peptide levels were associated with left ventricular hypertrophy on electrocardiogram (odds ratio: 3.10; p N-terminal pro brain natriuretic peptide levels were also significantly associated with ejection fraction on urine chorionic gonadotrophin (ultrasonic cardiography; odds ratio: 35.83; p N-terminal pro brain natriuretic peptide reduction ratio during a hemodialysis session correlated with Kt/V, membrane area, membrane type, modality, body weight gain ratio, treatment time, and ultrafiltration rate with multiple linear regression ( R: 0.53; p N-terminal pro brain natriuretic peptide are associated with the presence of left ventricular hypertrophy in this population. The post-hemodialysis N-terminal pro brain natriuretic peptide level is a useful marker for systolic dysfunction.

    Full Text Available Gastroesophageal reflux (GER has been reported as a cause of chronic cough (CC in the United States. It has been reported that 5–21% of CC cases are induced by GER. In Japan, however, detailed clinical features of CC induced by GER have not been described. The present study reports on six Japanese patients with GER-induced CC. The subjects were all females, with a mean age of 72 years. The average body mass index was 37 kg/m2, indicating obesity. No abnormalities were found with regard to concentrations of C-reactive protein, peripheral eosinophil counts, serum IgE concentrations, serum titers of cold agglutinins or antibodies to Mycoplasma pneumoniae, chest radiograph findings, respiratory function tests or blood gas analyses. Bronchial biopsy was performed in three patients and showed chronic inflammation characterized by lymphocytic infiltration, squamous metaplasia and mucosal basement membrane thickening. In the study population (Japanese patients, GER-induced CC tended to occur in elderly obese women and may be attributable to airway inflammation.

  20. The Paradigm Shift to Non-Treatment of Asymptomatic Bacteriuria.

    Nicolle, Lindsay E

    2016-04-19

    Asymptomatic bacteriuria, also called asymptomatic urinary infection, is a common finding in healthy women, and in women and men with abnormalities of the genitourinary tract. The characterization and introduction of the quantitative urine culture in the 1950s first allowed the reliable recognition of asymptomatic bacteriuria. The observations that a substantial proportion of patients with chronic pyelonephritis at autopsy had no history of symptomatic urinary infection, and the high frequency of pyelonephritis observed in pregnant women with untreated asymptomatic bacteriuria, supported a conclusion that asymptomatic bacteriuria was harmful. Subsequent screening and long term follow-up programs for asymptomatic bacteriuria in schoolgirls and women reported an increased frequency of symptomatic urinary tract infection for subjects with asymptomatic bacteriuria, but no increased morbidity from renal failure or hypertension, or increased mortality. Treatment of asymptomatic bacteriuria did not decrease the frequency of symptomatic infection. Prospective, randomized, comparative trials enrolling premenopausal women, children, elderly populations, patients with long term catheters, and diabetic patients consistently report no benefits with antimicrobial treatment of asymptomatic bacteriuria, and some evidence of harm. Several studies have also reported that antimicrobial treatment of asymptomatic bacteriuria increases the short term risk of pyelonephritis. Current investigations are exploring the potential therapeutic intervention of establishing asymptomatic bacteriuria with an avirulent Escherichia coli strain to prevent symptomatic urinary tract infection for selected patients.

    Patients with gastroesophageal reflux disease (GERD) frequently have symptoms of dyspepsia in addition to reflux symptoms. Treatment options for dyspepsia are not standardized. The aim of this study was to clarify the therapeutic effect of lansoprazole on dyspepsia in Japanese patients with GERD. GERD patients with dyspepsia were enrolled and treated with lansoprazole 15 or 30 mg once daily for 4 weeks. Reflux and dyspeptic symptoms were assessed by questionnaires before treatment, and 2 and 4 weeks after the start of lansoprazole treatment. In the effectiveness analysis set (n = 12,653), heartburn was reported by 91.6 % of patients at study enrollment. Postprandial fullness was the most frequently reported dyspepsia symptom at the start of the study, reported by 79.0 % of enrolled patients. After 4 weeks of lansoprazole treatment, heartburn symptoms were improved in 75.7 % of patients and symptoms of postprandial fullness were improved in 68.7 % of patients. The therapeutic effect of low and high doses of lansoprazole on dyspepsia, as well as on reflux symptoms, was approximately 10 % higher in patients with endoscopy-confirmed erosive esophagitis (60.1-82.2 %), than in patients with non-erosive reflux diseases (53.0-73.3 %). Lansoprazole was well tolerated. In this large-scale clinical study, lansoprazole effectively relieved dyspepsia in addition to reflux symptoms in patients with GERD.

    In Japan, there are currently no reliable rating scales for the evaluation of subjective cognitive impairment in patients with bipolar disorder. We studied the relationship between the Japanese version of the Cognitive Complaints in Bipolar Disorder Rating Assessment (COBRA) and objective cognitive assessments in patients with bipolar disorder. We further assessed the reliability and validity of the COBRA. Forty-one patients, aged 16-64, in a remission period of bipolar disorder were recruited from Hokkaido University Hospital in Sapporo, Japan. The COBRA (Japanese version) and Frankfurt Complaint Questionnaire (FCQ), the gold standard in subjective cognitive assessment, were administered. A battery of neuropsychological tests was employed to measure objective cognitive impairment. Correlations among the COBRA, FCQ, and neuropsychological tests were determined using Spearman's correlation coefficient. The Japanese version of the COBRA had high internal consistency, good retest reliability, and concurrent validity-as indicated by a strong correlation with the FCQ. A significant correlation was also observed between the COBRA and objective cognitive measurements of processing speed. These findings are the first to demonstrate that the Japanese version of the COBRA may be clinically useful as a subjective cognitive impairment rating scale in Japanese patients with bipolar disorder.

    Detection of previous cerebral infarction on CT films of patients with no history of stroke is a common occurrence. The incidence of silent cerebral infarction was reported to be about 10 to 11 percent, but very few reports concerning asymptomatic cerebral hemorrhage available. However, recent clinical application of MRI has resulted in the detection of old asymptomatic hemorrhage in patients with no history known stroke-like episodes. The purpose of this study was to elucidate the incidence, the cause and the character of the asymptomatic cerebral hemorrhage among patients who had undergone MRI examinations. From September 1987 through June 1990, 2757 patients have undergone 3474 MR scans of the brain with 1.0 Tesla Siemens Magneton unit in our hospital. Seventeen patients showed no clinical signs or symptoms suggesting a stroke episode corresponding to the detected hemorrhagic lesion. The 17 patients corresponded to 0.6% of the patients who underwent MRI, 1.5% of the patients with cerebrovascular disease and 9.5% of the patients with intracerebral hemorrhage(ICH), which was rather higher than expected. Among the 17 patients, 12 were diagnosed as primary ICH and 5 as secondary ICH. Most of the primary asymptomatic hemorrhage were hypertensive ones and slit-like curvilinear lesions between the putamen and claustrum or external capsule. The secondary asymptomatic hemorrhage were due to AVM and angiomas in the frontal cortex, thalamus and pons. (author)

    In asymptomatic patients with ≥3+ mitral regurgitation and preserved left ventricular (LV) ejection fraction who underwent mitral valve surgery, we sought to discover whether baseline LV global longitudinal strain (LV-GLS) and brain natriuretic peptide provided incremental prognostic utility. Four hundred and forty-eight asymptomatic patients (61±12 years and 69% men) with ≥3+ primary mitral regurgitation and preserved left ventricular ejection fraction, who underwent mitral valve surgery (92% repair) at our center between 2005 and 2008, were studied. Baseline clinical and echocardiographic data (including LV-GLS using Velocity Vector Imaging, Siemens, PA) were recorded. The Society of Thoracic Surgeons score was calculated. The primary outcome was death. Mean Society of Thoracic Surgeons score, left ventricular ejection fraction, mitral effective regurgitant orifice, indexed LV end-diastolic volume, and right ventricular systolic pressure were 4±1%, 62±3%, 0.55±0.2 cm(2), 58±13 cc/m(2), and 37±15 mm Hg, respectively. Forty-five percent of patients had flail. Median log-transformed BNP and LV-GLS were 4.04 (absolute brain natriuretic peptide: 60 pg/dL) and -20.7%. At 7.7±2 years, death occurred in 41 patients (9%; 0% at 30 days). On Cox analysis, a higher Society of Thoracic Surgeons score (hazard ratio 1.55), higher baseline right ventricular systolic pressure (hazard ratio 1.11), more abnormal LV-GLS (hazard ratio 1.17), and higher median log-transformed BNP (hazard ratio 2.26) were associated with worse longer-term survival (all Pright ventricular systolic pressure) provided incremental prognostic utility (χ(2) for longer-term mortality increased from 31-47 to 61; Pleft ventricular ejection fraction who underwent mitral valve surgery, brain natriuretic peptide and LV-GLS provided synergistic risk stratification, independent of established factors. © 2016 American Heart Association, Inc.

    The present study was conducted to accurately determine the presence of mild cognitive impairment, which is often difficult to evaluate using only simple tests. Our approach focused on discrepancy analysis of fluid intelligence relative to crystallized intelligence using internationally recognized neuropsychological tests. One-hundred and five patients diagnosed with asymptomatic carotid artery stenosis were assessed. The neuropsychological tests included the two subtests (information and picture completion) of Wechsler Adult Intelligence Scale-Revised (WAIS-R-two-subtests): crystallized intelligence tests and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) (immediate memory, visuospatial/constructional, language, attention, delayed memory and total score) as fluid intelligence tests. Discrepancy analysis was used to assess cognitive impairment. The score for RBANS was subtracted from the score for WAIS-R-two-subtests, and if the score difference was greater than the 5% confidence limit for statistical significance, it was defined as a decline in cognitive function. The WAIS-R-two-subsets was within normal limits when compared with the standardized values. However, all RBANS domains showed significant declines. Frequencies of decline in each RBANS domain were as follows: 69 patients (66%) in immediate memory, 26 (25%) in visuospatial/constructional, 54 (51%) in language, 63 (60%) in attention, 54 (51%) in delayed memory and 78 (74%) in the total score. Moreover, 99 patients (94%) showed decline in at least one RBANS domain. Cognitive function is only preserved in a few patients with asymptomatic carotid artery stenosis. Mild cognitive impairment can be precisely detected by performing the discrepancy analysis between crystallized and fluid intelligence tests. © 2017 EAN.

    To investigate whether atherogenic dyslipidemia, a dyslipidemic profile combining elevated triglycerides and low high-density lipoprotein (HDL) cholesterol, is predictive of risk of silent myocardial ischemia (SMI) or angiographic coronary artery disease (CAD) in asymptomatic patients with type 2 diabetes. Cohort study in 1080 asymptomatic patients with type 2 diabetes with a normal resting electrocardiogram, at least one additional cardiovascular risk factor and low density lipoprotein (LDL) cholesterol dyslipidemia (triglycerides ≥2.26 mmol/L and HDL cholesterol ≤0.88 mmol/L). In multivariate analyses taking into account the parameters associated in univariate analyses with SMI and then CAD, atherogenic dyslipidemia was associated with SMI (odds ratio 1.8[1.0-3.3]), as were male gender (OR 2.1[1.5-2.9]), BMI (OR 0.97[0.94-0.997]), retinopathy (OR 1.4[1.1-1.9]), peripheral occlusive arterial disease (POAD: OR 2.5[1.6-3.8]) and mean blood pressure (OR 1.01[1.00-1.03]); atherogenic dyslipidemia was associated with CAD (OR 4.0[1.7-9.2]), as were male gender (OR 3.0[1.6-5.6]), BMI (OR 0.94[0.90-0.995]), retinopathy (OR 1.7[1.0-2.9], POAD (OR 4.0[2.1-7.4]) and mean blood pressure (OR 1.03[1.01-1.05]). In the subgroup of 584 patients with LDL cholesterol dyslipidemia was also associated with CAD (OR 3.6[1.5-9.0]). Atherogenic dyslipidemia was associated with an increased risk of SMI and silent CAD in patients with type 2 diabetes and LDL cholesterol levels dyslipidemia might help reducing the high residual burden of cardiovascular disease.

    Human T-lymphotropic virus-type 1 (HTLV-1) is the etiologic agent of the neurologic disease HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Tax viral protein plays a critical role in viral pathogenesis. Previous studies suggested that extracellular Tax might involve cytokine-like extracellular effects. We evaluated Tax secretion in 18 h-ex vivo peripheral blood mononuclear cells (PBMCs) cultures from 15 HAM/TSP patients and 15 asymptomatic carriers. Futhermore, Tax plasma level was evaluated from other 12 HAM/TSP patients and 10 asymptomatic carriers. Proviral load and mRNA encoding Tax were quantified by PCR and real-time RT-PCR, respectively. Intracellular Tax in CD4(+)CD25(+) cells occurred in 100% and 86.7% of HAM/TSP patients and asymptomatic carriers, respectively. Percentage of CD4(+)CD25(+) Tax+, proviral load and mRNA encoding Tax were significantly higher in HAM/TSP patients. Western blot analyses showed higher secretion levels of ubiquitinated Tax in HAM/TSP patients than in asymptomatic carriers. In HTLV-1-infected subjects, Western blot of plasma Tax showed higher levels in HAM/TSP patients than in asymptomatic carriers, whereas no Tax was found in non-infected subjects. Immunoprecipitated plasma Tax resolved on SDS-PAGE gave two major bands of 57 and 48 kDa allowing identification of Tax and Ubiquitin peptides by mass spectrometry. Relative percentage of either CD4(+)CD25(+) Tax+ cells, or Tax protein released from PBMCs, or plasma Tax, correlates neither with tax mRNA nor with proviral load. This fact could be explained by a complex regulation of Tax expression. Tax secreted from PBMCs or present in plasma could potentially become a biomarker to distinguish between HAM/TSP patients and asymptomatic carriers. © 2015 Wiley Periodicals, Inc.

    Full Text Available Aims: In the present study, we investigated whether apolipoprotein E (APOE polymorphisms influenced the cognitive function of Japanese patients with Alzheimer's disease (AD at certain ages. Methods: Among 200 outpatients with dementia and amnestic mild cognitive impairment, 133 Japanese patients with AD were recruited and divided into two genotypic groups: APOE ε4 carriers and noncarriers. Then, we compared several neuropsychological test scores between the two genotypic groups for two different generations: 70s (70-79 years and 80s (80-89 years. Results: The total Mini-Mental State Examination score (p Conclusion: The present results suggest that APOE may significantly influence comparatively simple memory processing in certain generations of Japanese patients with AD.

  11. Social orientation and diabetes-related distress in Japanese and American patients with type 2 diabetes.

    Kaori Ikeda

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

    The Passive Neck Flexion Test (PNFT) can diagnose meningitis and potential spinal disorders. Little evidence is available concerning the use of a modified version of the PNFT (mPNFT) in patients with chronic nonspecific neck pain (CNSNP). To assess the reliability of the mPNFT in subjects with and without CNSNP. The secondary objective was to assess the differences in the symptoms provoked by the mPNFT between these two populations. We used repeated measures concordance design for the main objective and cross-sectional design for the secondary objective. A total of 30 asymptomatic subjects and 34 patients with CNSNP were recruited. The following measures were recorded: the range of motion at the onset of symptoms (OS-mPNFT), the range of motion at the submaximal pain (SP-mPNFT), and evoked pain intensity on the mPNFT (VAS-mPNFT). Good to excellent reliability was observed for OS-mPNFT and SP-mPNFT in the asymptomatic group (intra-examiner reliability: 0.95-0.97; inter-examiner reliability: 0.86-0.90; intra-examiner test-retest reliability: 0.84-0.87). In the CNSNP group, a good to excellent reliability was obtained for the OS-mPNFT (intra-examiner reliability: 0.89-0.96; inter-examiner reliability: 0.83-0.86; intra-examiner test-retest reliability: 0.83-0.85) and the SP-PNFT (intra-examiner reliability: 0.94-0.98; inter-examiner reliability: 0.80-0.82; intra-examiner test-retest reliability: 0.88-0.91). The CNSNP group showed statistically significant differences in OS-mPNFT (t = 4.92; P reliable tool regardless of the examiner and the time factor. Patients with CNSNP have a decrease range of motion and more pain than asymptomatic subjects in the mPNFT. This exceeds the minimal detectable changes for OS-mPNFT and VAS-mPNFT.

    2017-03-01

    Full Text Available Background: Breast cancer is currently the most common type of cancer in Japanese females. Unlike most other types of cancer, breast cancer develops more frequently in middle-aged females than in elderly females. Methods: Of all Japanese female breast cancer patients aged ≥20 years whom the BioBank Japan Project originally enrolled between 2003 and 2008, 2034 were registered within 90 days after their diagnosis. We described the lifestyle and clinical characteristics of these patients at study entry. Furthermore, we examined the effect of these characteristics on all-cause mortality. Results: In the female patients registered within 90 days after diagnosis, the frequency of stage 0 or unclassified, stage I, II, III and IV were 11.4%, 47.9%, 37.0%, 2.9% and 0.8%, respectively. The proportion of histological types was 12.9% for non-invasive carcinoma (ductal carcinoma and lobular carcinoma, 81.0% for invasive carcinoma (papillotubular carcinoma, solid tubular carcinoma, scirrhous carcinoma and special types, 0.2% for Paget’s diseases and 5.8% for others. Those positive for the estrogen and progesterone receptors accounted for 75.8% and 62.1% of all patients, respectively. Among 1860 female participants registered within 90 days, 218 participants died during 144,54 person-years of follow-up. More advanced stage, elevation of serum carcinoembryonic antigen and carbohydrate antigen 15-3 levels and absence of the estrogen receptor at study entry were crudely associated with an increased risk of all-cause mortality after adjustment for age. Conclusions: This study showed the association of several clinical characteristics with all-cause mortality in female breast cancer patients.

    2001-01-01

    Pregnancy is a predisposing factor for urinary tract infection and pregnant women suffering from this pathology are exposed to dangerous risks which may condition maternal wellbeing and fetal prognosis. Asymptomatic bacteriuria is the common bacterial infection requiring medical treatment in pregnancy. Diagnosis and treatment of asymptomatic bacteriuria is important as approximately 20-40% of these women, if untreated during pregnancy, will develop a symptomatic urinary tract infection.

  15. Genetic and infectious profiles influence cerebrospinal fluid IgG abnormality in Japanese multiple sclerosis patients.

    Satoshi Yoshimura

    Full Text Available BACKGROUND: Abnormal intrathecal synthesis of IgG, reflected by cerebrospinal fluid (CSF oligoclonal IgG bands (OBs and increased IgG index, is much less frequently observed in Japanese multiple sclerosis (MS cohorts compared with Western cohorts. We aimed to clarify whether genetic and common infectious backgrounds influence CSF IgG abnormality in Japanese MS patients. METHODOLOGY: We analyzed HLA-DRB1 alleles, and IgG antibodies against Chlamydia pneumoniae, Helicobacter pylori, Epstein-Barr virus nuclear antigen (EBNA, and varicella zoster virus (VZV in 94 patients with MS and 367 unrelated healthy controls (HCs. We defined CSF IgG abnormality as the presence of CSF OBs and/or increased IgG index (>0.658. PRINCIPAL FINDINGS: CSF IgG abnormality was found in 59 of 94 (62.8% MS patients. CSF IgG abnormality-positive patients had a significantly higher frequency of brain MRI lesions meeting the Barkhof criteria compared with abnormality-negative patients. Compared with HCs, CSF IgG abnormality-positive MS patients showed a significantly higher frequency of DRB1 1501, whereas CSF IgG abnormality-negative patients had a significantly higher frequency of DRB1 0405. CSF IgG abnormality-positive MS patients had a significantly higher frequency of anti-C. pneumoniae IgG antibodies compared with CSF IgG abnormality-negative MS patients, although there was no difference in the frequency of anti-C. pneumoniae IgG antibodies between HCs and total MS patients. Compared with HCs, anti-H. pylori IgG antibodies were detected significantly less frequently in the total MS patients, especially in CSF IgG abnormality-negative MS patients. The frequencies of antibodies against EBNA and VZV did not differ significantly among the groups. CONCLUSIONS: CSF IgG abnormality is associated with Western MS-like brain MRI features. DRB1 1501 and C. pneumoniae infection confer CSF IgG abnormality, while DRB1 0405 and H. pylori infection are positively and negatively

    2011-01-01

    The aim of this study was to examine the attitudes among Japanese nurses together with their perceived need for training in relation to understanding the nature of suicidal behavior and preventive strategies. The Understanding Suicidal Patients scale together with additional questions reflecting training and the psychiatric treatment of suicide attempters were administered. A total of 323 nurses attended this study. Overall, the nurses thought patients who attempted suicide were not treated well. The nurses who worked in the psychiatric unit or had the experience in psychiatric nursing had more favorable attitudes toward suicidal patients and viewed themselves as having more relevant skill training in dealing with suicidal patients than those who did not. The nurses who worked at emergency care/intensive care unit were less likely to understand suicidal patients, and were less inclined to be sympathetic and to verbally interact with suicidal patients concerning their problems. The nurses who have confidence in the psychiatric care of suicidal patients, confidence in their own skills, and have a need for more training had the more positive attitudes. The results suggest that less favorable attitudes may to some extent be the result of lack of knowledge regarding suicidal patients. Future studies should focus on the evaluation of educational experiences on attitudes and skill acquisition of nurses. Copyright © 2011 Elsevier Inc. All rights reserved.

  17. Blastocystis Isolates from Patients with Irritable Bowel Syndrome and from Asymptomatic Carriers Exhibit Similar Parasitological Loads, but Significantly Different Generation Times and Genetic Variability across Multiple Subtypes.

    Gie-Bele Vargas-Sanchez

    Full Text Available Blastocystis spp is a common intestinal parasite of humans and animals that has been associated to the etiology of irritable bowel syndrome (IBS; however, some studies have not found this association. Furthermore, many biological features of Blastocystis are little known. The objective of present study was to assess the generation times of Blastocystis cultures, from IBS patients and from asymptomatic carriers. A total of 100 isolates were obtained from 50 IBS patients and from 50 asymptomatic carriers. Up to 50 mg of feces from each participant were cultured in Barret's and in Pavlova's media during 48 h. Initial and final parasitological load were measured by microscopy and by quantitative PCR. Amplicons were purified, sequenced and submitted to GenBank; sequences were analysed for genetic diversity and a Bayesian inference allowed identifying genetic subtypes (ST. Generation times for Blastocystis isolates in both media, based on microscopic measures and molecular assays, were calculated. The clinical symptoms of IBS patients and distribution of Blastocystis ST 1, 2 and 3 in both groups was comparable to previous reports. Interestingly, the group of cases showed scarce mean nucleotide diversity (π as compared to the control group (0.011±0.016 and 0.118±0.177, respectively, whilst high gene flow and small genetic differentiation indexes between different ST were found. Besides, Tajima's D test showed negative values for ST1-ST3. No statistical differences regarding parasitological load between cases and controls in both media, as searched by microscopy and by qPCR, were detected except that parasites grew faster in Barret's than in Pavlova's medium. Interestingly, slow growth of isolates recovered from cases in comparison to those of controls was observed (p<0.05. We propose that generation times of Blastocystis might be easily affected by intestinal environmental changes due to IBS probably because virulent strains with slow growth may be

    Full Text Available Takashi Hitsumoto,1 Kohji Shirai2 1Hitsumoto Medical Clinic, Yamaguchi, Japan; 2Department of Vascular Function (donated, Sakura Hospital, Toho University School of Medicine, Chiba, Japan Purpose: The blood concentration of cardiac troponin T (ie, high-sensitivity cardiac troponin T [hs-cTnT], measured using a highly sensitive assay, represents a useful biomarker for evaluating the pathogenesis of heart failure or predicting cardiovascular events. However, little is known about the clinical significance of hs-cTnT in metabolic syndrome. The aim of this study was to examine the factors affecting hs-cTnT elevation in Japanese metabolic syndrome patients. Patients and methods: We enrolled 258 metabolic syndrome patients who were middle-aged males without a history of cardiovascular events. We examined relationships between hs-cTnT and various clinical parameters, including diagnostic parameters of metabolic syndrome. Results: There were no significant correlations between hs-cTnT and diagnostic parameters of metabolic syndrome. However, hs-cTnT was significantly correlated with age (P<0.01, blood concentrations of brain natriuretic peptide (P<0.01, reactive oxygen metabolites (markers of oxidative stress, P<0.001, and the cardio–ankle vascular index (marker of arterial function, P<0.01. Furthermore, multiple regression analysis revealed that these factors were independent variables for hs-cTnT as a subordinate factor. Conclusion: The findings of this study indicate that in vivo oxidative stress and abnormality of arterial function are closely associated with an increase in hs-cTnT concentrations in Japanese metabolic syndrome patients. Keywords: troponin, metabolic syndrome, risk factor, oxidative stress, cardio–ankle vascular index

  19. Asymptomatic bacteriuria and urinary tract infections in special patient groups: women with diabetes mellitus and pregnant women.

    Schneeberger, Caroline; Kazemier, Brenda M; Geerlings, Suzanne E

    2014-02-01

    Asymptomatic bacteriuria (ASB) and urinary tract infections (UTIs) in women with diabetes mellitus and during pregnancy are common and can have far-reaching consequences for the woman and neonate. This review describes epidemiology, risk factors, complications and treatment of UTI and ASB according to recent developments in these two groups. Most articles addressing the epidemiology and risk factors of ASB and UTI in diabetic and pregnant women confirmed existing knowledge. New insights were obtained in the association between sodium-glucose cotransporter-2 (SGLT2) inhibitors, as medication for diabetes mellitus type 2, and a small increased risk for UTI due to glucosuria and the possible negative effects of UTI, including urosepsis,on bladder and kidney function in diabetic women. Predominantly, potential long-term effects of antibiotic treatment of ASB or UTI during pregnancy on the neonate have received attention, including antibiotic resistance and epilepsy. SGLT2 inhibitors were associated with a small increased risk for UTI, UTI in diabetic women may lead to bladder and kidney dysfunction, and antibiotic treatment of ASB and UTI during pregnancy was associated with long-term effects on the neonate. Up-to-date research on the effectiveness and long-term effects of ASB screening and treatment policies, including group B Streptococcus bacteriuria in pregnancy, is warranted to inform clinical practice.

    2014-06-01

    We studied the features of upper gastrointestinal bleeding (UGIB) in patients taking antithrombotic drugs. The records of 430 patients taking antithrombotic drugs who underwent emergency endoscopy for UGIB in Saga Medical School Hospital between 2002 and 2011 were studied. We also compared the characteristics of our cohort of 11,919 patients prescribed antithrombotic drugs in our hospital between 2002 and 2011. UBGI patients of variceal bleeding were not included in this study. 186 patients presented with UGIB in the first period (2002-2006) and 244 in the second period (2007-2011). The proportion of patients infected with Helicobacter pylori was lower in the second period, while the proportion taking antithrombotic drugs rose significantly. Peptic ulcer disease was responsible for the majority of bleeding episodes; however, bleeding from other sources is increasing. In the whole cohort, the risk of UGIB was 1.08%; however, of the 31.8% who also took an acid-secretion inhibitor only 18 (0.28%) developed bleeding. In contrast, 102 (1.87%) of those not taking an acid-secretion inhibitor developed UGIB, a statistically significant difference. Risk of UGIB in Japanese patients taking antithrombotics was 1.01% and the incidence is increasing. Acid-secretion inhibitors reduced the risk of antithrombotic drug-related UGIB.

    Full Text Available Background/Aims: Predictors including the preventive effects of antiplatelet and anticoagulant drugs on cerebral infarction (CI events have not yet been clarified in dialysis patients. The aim of the present study was to examine the risk of CI and preventive effects of these drugs in Japanese hemodialysis patients. Methods: Patients receiving maintenance hemodialysis (n=1,551, median age (interquartile range, 69.0 (59.0-78.0 years; 41.5% female were enrolled in the Miyazaki Dialysis Cohort Study and prospectively followed-up for 3 years. Kaplan-Meier and Cox's regression analyses were used to clarify the risk of CI. Results: Eighty-four patients developed CI at an incidence of 21.5/1000 patients per year. The presence of a previous history of CI, atrial fibrillation (AF, and diabetes mellitus in addition to age were also identified as predictive factors for new CI, whereas no relationship was observed between antiplatelet and/or anticoagulant usage and CI. Furthermore, no significant difference was noted in the frequency of CI events between patients with AF who received warfarin and those who did not. Conclusions: The incidence of CI was higher in dialysis patients with a previous history of CI and AF; however, the preventive effects of antiplatelet/anticoagulant drugs on the development of CI were not evident.

    The natural history of cerebral aneurysms was investigated by measuring the prevalence of incidentally found unruptured aneurysms in the general population and evaluating the characteristics including risk factors. 'De novo' formation of aneurysm was also demographically estimated. The prevalence of incidental aneurysm was evaluated among 4518 patients who underwent magnetic resonance (MR) angiography for various reasons in a neurosurgical institute. Double the number of patients were randomly selected from the remaining patients without aneurysm as the Control group so that sex and age group were matched to the Aneurysm group. One hundred twenty seven patients (2.8%) had diagnoses of aneurysm. The prevalence of asymptomatic aneurysm among middle-aged and elderly patients were predominant in women and increased with age in both sexes. Patients with aneurysms had significantly more hypertension and family history of subarachnoid hemorrhage compared to the controls. The prevalence was markedly increased in the 8th decade in men and the 7th decade in women, and new aneurysms seemed to develop predominantly around these decades. Cerebral aneurysms become detectable on MR angiography in the middle or later decades, and women tend to develop aneurysm earlier than men. Hypertension and family history of subarachnoid hemorrhage are probably risk factors for the development of aneurysm. (author)

    Full Text Available In asymptomatic Marfan syndrome (MFS patients we evaluated the relationship between the types of fibrillin-1 (FBN1 gene mutation and possible altered left ventricular (LV function as assessed by three-dimensional speckle tracking echocardiography (3D-STE.Forty-five MFS patients (mean age 24 ± 15 years and 40 age-matched healthy controls were studied. Genetic evaluation for the FBN1 gene was carried on 32 MFS patients. Gene mutation (n = 15, 47% was classified as mild when the mutation resulted in nearly normally functioning protein, while mutations resulting in abnormally function protein were considered to be severe (n = 17, 53%. All patients and controls underwent 3D-STE for evaluation of LV function by an echocardiographer blinded to the results of the genetic testing. Compared to controls, MFS patients had significantly lower 3D-STE derived LV ejection fraction (EF, 57.43 ± 7.51 vs. 62.69 ± 4.76%, p = 0.0001, global LV longitudinal strain (LS, 14.85 ± 2.89 vs. 17.90 ± 2.01%, p = 0.0001, global LV circumferential strain (CS, 13.93 ± 2.81 vs. 16.82 ± 2.17%, p = 0.0001 and global LV area strain (AS, 25.76 ± 4.43 vs. 30.51 ± 2.61%, p = 0.0001. Apart from the global LV LS all these parameters were significantly lower in patients with severe gene mutation than in those with mild mutation (p < 0.05. In the multivariate linear regression analysis only the type of mutation had a significant influence on the 3D-STE derived LVEF (p = 0.017, global CS (p = 0.005 and global AS (p = 0.03.In asymptomatic MFS patients latent LV dysfunction can be detected using 3D STE. The LV dysfunction is mainly related to the severity of gene mutation, suggesting possible primary cardiomyopathy in MFS patients.

    Ten to 15% of first-degree relatives (FDRs) of celiac disease (CeD) patients develop CeD. Although intestinal barrier functions (intestinal permeability) are abnormal in the subset of serology-negative FDRs, what leads to the abnormal barrier function is not known. To study the ultrastructure and functions of tight junctions in serology-negative FDRs of CeD patients. The intestinal permeability was measured in 97 asymptomatic and anti-tissue transglutaminase antibody (anti-tTG Ab)-negative FDRs (using the lactulose mannitol ratio) and in 75 controls. The ultrastructure of tight junctions using transmission electron microscopy, and the expression of key tight junction proteins (claudin-2, claudin-3, occludin, JAM-A, and ZO-1) and zonulin using real-time PCR and immunohistochemistry were assessed in anti-tTG Ab-negative, HLA-DQ2/-DQ8-positive FDRs having normal villi and in disease controls. In addition, the serum zonulin level was measured in 172 anti-tTG Ab-negative FDRs and 198 controls. The intestinal permeability was significantly increased in FDRs than in controls. Ultrastructural abnormalities such as dilatation of the tight junction (P=0.004) and loss of the pentalaminar structure (P=0.001) were more common in FDRs than in disease controls. There was significant underexpression of tight junction proteins ZO-1 (P=0.040) and occludin (P=0.041) in FDRs. There was no significant difference in the serum zonulin level between FDRs and controls (P=0.154). Even asymptomatic, anti-tTG-Ab-negative FDRs with a normal villous histology have both ultrastructural and functional abnormalities in tight junctions. These findings are indirect evidence of the presence of tight junction abnormalities before the onset of the disease and may have therapeutic implications.

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

  7. Asymptomatic bacteriuria: review and discussion of the IDSA guidelines.

    Nicolle, Lindsay E

    2006-08-01

    Asymptomatic bacteriuria is a common finding, but is usually benign. Screening and treatment of asymptomatic bacteriuria is only recommended for pregnant women, or for patients prior to selected invasive genitourinary procedures. Healthy women identified with asymptomatic bacteriuria on population screening subsequently experience more frequent episodes of symptomatic infection, but antimicrobial treatment of asymptomatic bacteriuria does not decrease the occurrence of these episodes. Clinical trials in spinal-cord injury patients, diabetic women, patients with indwelling urethral catheters, and elderly nursing home residents have consistently found no benefits with treatment of asymptomatic bacteriuria. Negative outcomes with antimicrobial treatment do occur, including adverse drug effects and re-infection with organisms of increasing resistance. Optimal management of asymptomatic bacteriuria requires appropriate implementation of screening strategies to promote timely identification of the selected patients for whom treatment is beneficial, and avoidance of antimicrobial therapy where no benefit has been shown.

    2009-01-01

    A nationwide survey was performed to investigate the current patterns of care for brain metastasis (BM) from breast cancer in Japan. A total of 351 survey questionnaires were sent to community or academic breast oncologists who were members of the Japanese Breast Cancer Society as of December 2005. The questionnaire consists of 40 multiple choice questions in eight categories. Of 240 institutions sent survey questionnaires, 161 (67.1%) answered; 60% of institutions answered with '<5' patients with BM every year; almost half (83 of 161) screened for BM in asymptomatic patients; surgical resection was rarely performed, as ∼75% of institutions (118 of 160 institutions) answered 'none or one case of surgery per year'; 27% (41 of 154) preferred stereotactic radiosurgery (SRS) over whole-brain radiotherapy (WBRT) as the initial treatment in all cases, although ∼70% (100 of 154) of them answered 'depend on cases'. The preference for SRS over WBRT mainly depends on the impressions of breast oncologists about both safety (late normal tissue damage and dementia in WBRT) and efficacy (better local control by SRS). Eighty-one percent (117 of 144) of institutions did not limit the number of SRS sessions as far as technically applicable. SRS is widely used as the first choice for BM from breast cancer in Japan. Considerable numbers of Japanese breast oncologists prefer SRS over WBRT as the initial treatment for BM. A randomized trial comparing SRS and WBRT is warranted. (author)

    Human papillomavirus (HPV) is a major etiologic factor for oropharyngeal squamous cell carcinoma (OPSCC). However, little is known about HPV-related OPSCC in Japan. During the study, formalin-fixed, paraffin-embedded OPSCC specimens from Japanese patients were analyzed for HPV DNA by the polymerase chain reaction (PCR) and for the surrogate marker p16 by immuno-histochemistry. For HPV DNA-positive, p16-negative specimens, the methylation status of the p16 gene promoter was examined by methylation-specific PCR. Overall survival was calculated in relation to HPV DNA and p16 status and was subjected to multivariate analysis. OPSCC cell lines were examined for sensitivity to radiation or cisplatin in vitro. The study results showed that tumor specimens from 40 (38%) of the 104 study patients contained HPV DNA, with such positivity being associated with tumors of the tonsils, lymph node metastasis, and nonsmoking. Overall survival was better for OPSCC patients with HPV DNA than for those without it (hazard ratio, 0.214; 95% confidence interval, 0.074–0.614; P = 0.002). Multivariate analysis revealed HPV DNA to be an independent prognostic factor for overall survival (P = 0.015). Expression of p16 was associated with HPV DNA positivity. However, 20% of HPV DNA-positive tumors were negative for p16, with most of these tumors manifesting DNA methylation at the p16 gene promoter. Radiation or cisplatin sensitivity did not differ between OPSCC cell lines positive or negative for HPV DNA. Thus, positivity for HPV DNA identifies a distinct clinical subset of OPSCC with a more favorable outcome in Japanese

    Many patients with chronic spontaneous/idiopathic urticaria (CSU/CIU) do not respond adequately to treatment with non-sedating H1 antihistamines (H1AH). There are limited studies on use of omalizumab as add-on therapy for treatment of CSU in an Asian population. The POLARIS study (NCT02329223), representing the first randomized, double-blind, placebo-controlled phase III trial of omalizumab for CSU in an Eastern Asian population, evaluated efficacy and safety of omalizumab as add-on therapy for treatment of CSU. This 26-week multicenter (41 Japanese/Korean sites) study enrolled patients (12-75 years) who were symptomatic despite H1AH treatment. Eligible participants (N=218) were randomized 1:1:1 to receive three subcutaneous injections of omalizumab 300mg, 150mg, or placebo every 4 weeks, followed by 12 weeks of follow-up. Primary outcome was change from baseline to Week 12 (Wk12) in weekly itch severity score (ISS7). Safety was assessed through the summary of adverse events (AEs). Baseline demographics and disease characteristics were generally well balanced across treatment groups. At Wk12, statistically significant decreases from baseline were observed in ISS7 with omalizumab vs placebo (mean changes -10.22, -8.80, and -6.51 for omalizumab 300mg, 150mg and placebo; pomalizumab 300mg, 150mg, and placebo groups, respectively); nasopharyngitis was the most frequently reported AE in all treatment arms. The POLARIS study demonstrates that omalizumab is an efficacious and well-tolerated add-on therapy in Japanese and Korean H1AH-refractory patients with CSU. Copyright © 2017 The Authors.

    To search for mutations in the Norrie disease gene (NDP) in Japanese patients with familial exudative vitreoretinopathy (FEVR) and Norrie disease (ND) and to delineate the mutation-associated clinical features. Direct sequencing after polymerase chain reaction of all exons of the NDP gene was performed on blood collected from 62 probands (31 familial and 31 simplex) with FEVR, from 3 probands with ND, and from some of their family members. The clinical symptoms and signs in the patients with mutations were assessed. X-inactivation in the female carriers was examined in three FEVR families by using leukocyte DNA. Four novel mutations-I18K, K54N, R115L, and IVS2-1G-->A-and one reported mutation, R97P, in the NDP gene were identified in six families. The severity of vitreoretinopathy varied among these patients. Three probands with either K54N or R115L had typical features of FEVR, whereas the proband with R97P had those of ND. Families with IVS2-1G-->A exhibited either ND or FEVR characteristics. A proband with I18K presented with significant phenotypic heterogeneity between the two eyes. In addition, affected female carriers in a family harboring the K54N mutation presented with different degrees of vascular abnormalities in the periphery of the retina. X-inactivation profiles indicated that the skewing was not significantly different between affected and unaffected women. These observations indicate that mutations of the NDP gene can cause ND and 6% of FEVR cases in the Japanese population. The X-inactivation assay with leukocytes may not be predictive of the presence of a mutation in affected female carriers.

    1987-01-01

    The authors reviewed the renal US clinical evaluation, and laboratory data of 78 pediatric patients referred for asymptomatic hematuria. Patients with known renal disease, trauma, mass, infection, or severe pain were excluded. Thirty-two presented with gross hematuria. Nine had abnormal findings on US (28%). Increased echogenicity was the most common abnormality. Forty-five presented with microscopic hematuria. Eight had abnormal findings on US (18%). Bladder wall thickening was the most common abnormality. All patients with renal disease or significant anatomic abnormalities presented with gross hematuria and/or associated abnormalities in history, physical examination, or urinalysis. In asymptomatic patients with microscopic hematuria, significant US abnormalities are rare

    The aim of this study was to investigate the relation between lower urinary tract symptoms (LUTS), erectile dysfunction (ED) and depression in Japanese patients with late-onset hypogonadism (LOH) symptoms. The study comprised 87 Japanese patients with LOH symptoms (>27 points on the Aging Males Symptoms Scale). Thirty-four patients were diagnosed as having depression and the remaining 53 patients were diagnosed as not having depression by the Mini International Neuropsychiatric Interview. We compared the International Index of Erectile Function (IIEF) 5, International Prostate Symptom Score (IPSS), IPSS quality-of-life (QOL) index, King's Health Questionnaire (KHQ), endocrinological data, and free uroflow study between depression and non-depression patients and performed multiple logistic regression analysis. IIEF5 scores of depression patients were significantly lower than those of non-depression patients. In KHQ, only the category of general health perceptions was significantly higher in depression patients than non-depression patients. However, IPSS, QOL index, and endocrinological and uroflowmetric data showed no significant difference between the groups. Multiple logistic regression analysis revealed moderate and severe ED to be risk factors for depression. However, LUTS are not related to depression. Moderate and severe ED is correlated with depression, whereas LUTS are not related to depression in Japanese LOH patients.

  14. Lymphoscintigraphy for sentinel lymph node mapping in Japanese patients with malignant skin neoplasms of the lower extremities. Comparison with previously investigated Japanese lymphatic anatomy

    Lymph nodes (LN) and lymphatic drainage were identified by lymphoscintigraphy using 99m Tc-phytate in order to map the sentinel lymph nodes (SLNs) in patients with malignant skin neoplasms of the lower extremities, and to compare the results with an atlas of Japanese lymphatic anatomy. Sentinel lymphoscintigraphs of 18 patients with malignant skin neoplasms of the lower extremities (9 men, 9 women; age range 45-84 years, mean age 66 years) were analyzed retrospectively, and the LNs detected were identified as SLNs or secondary nodes. The patterns of lymphatic drainage were divided into three different categories: initial drainage into inguinal LN without visualization of popliteal LNs (inguinal type), initial drainage into popliteal LNs and then into intrapelvic LNs (popliteal type), and initial drainage into both popliteal and inguinal LNs (inguinal and popliteal type). More than half of the cases were the inguinal and popliteal type, as both inguinal and popliteal LNs were identified as SLNs. In the cases in which the hallux and its surrounding area were injected, all were the inguinal type and popliteal LNs were not visualized. In one case, only dynamic images detected lymphatic drainage without visualization of popliteal LNs. In contrast to the previously published literature on Japanese lymphatic anatomy, SLN lymphatic drainage from the skin of the lower extremities was wide and overlapping in many areas. However, in agreement with currently accepted anatomy, only the great saphenous lymphatic vessel drained the skin of the hallux and its surrounding area. The present results suggest that it is important to confirm lymphatic drainage in order to identify SLNs in the lower extremities. The patterns of lymphatic drainage from the skin of the foot were divided into three different categories. In contrast to previously published Japanese lymphatic anatomy, lymphatic drainage from the skin of the lower extremities was wide and overlapping in many areas. However

    Sano, Shinichiro; Nakamura, Akie; Matsubara, Keiko; Nagasaki, Keisuke; Fukami, Maki; Kagami, Masayo

    2018-01-01

    Context: Pseudohypoparathyroidism type I (PHP-I) is divided into PHP-Ia with Albright hereditary osteodystrophy and PHP-Ib, which usually shows no Albright hereditary osteodystrophy features. Although PHP-Ia and PHP-Ib are typically caused by genetic defects involving α subunit of the stimulatory G protein (Gsα)–coding GNAS exons and methylation defects of the GNAS differentially methylated regions (DMRs) on the maternal allele, respectively, detailed phenotypic characteristics still remains to be examined. Objective: To clarify phenotypic characteristics according to underlying (epi)genetic causes. Patients and Methods: We performed (epi)genotype-phenotype analysis in 69 Japanese patients with PHP-I; that is, 28 patients with genetic defects involving Gsα-coding GNAS exons (group 1) consisting of 12 patients with missense variants (subgroup A) and 16 patients with null variants (subgroup B), as well as 41 patients with methylation defects (group 2) consisting of 21 patients with broad methylation defects of the GNAS-DMRs (subgroup C) and 20 patients with an isolated A/B-DMR methylation defect accompanied by the common STX16 microdeletion (subgroup D). Results: Although (epi)genotype-phenotype findings were grossly similar to those reported previously, several important findings were identified, including younger age at hypocalcemic symptoms and higher frequencies of hyperphosphatemia in subgroup C than in subgroup D, development of brachydactyly in four patients of subgroup C, predominant manifestation of subcutaneous ossification in subgroup B, higher frequency of thyrotropin resistance in group 1 than in group 2, and relatively low thyrotropin values in four patients with low T4 values and relatively low luteinizing hormone/follicle-stimulating hormone values in five adult females with ovarian dysfunction. Conclusion: The results imply the presence of clinical findings characteristic of each underlying cause and provide useful information on the imprinting

    Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis can increase the risk of cardiovascular disease (CVD). However, the detailed relationships of HPA axis activity with weight reduction and CVD risk factors in obese patients have not been examined. This study was designed to elucidate the associations of salivary cortisol levels with weight reduction and CVD risk factors in obese patients. As a marker of HPA axis activity, we measured the morning salivary cortisol levels of 83 obese Japanese outpatients. We also examined metabolic parameters, inflammatory markers, and indicators of arterial stiffness, that is, the pulse wave velocity and cardio-ankle vascular index. All 83 obese patients underwent 3-month weight reduction therapy with lifestyle modification. At the baseline, multivariate regression analysis revealed that only logarithmic transformation of C-reactive protein (β = 0.258, P cortisol levels. However, other metabolic parameters were not significantly associated with the salivary cortisol levels. In addition, lower salivary cortisol levels and higher body weight at the baseline were the only independent determinants of successful weight loss through the weight reduction therapy (P cortisol levels are significantly associated with the levels of an inflammatory marker, arterial stiffness, and successful weight reduction in obese patients. Therefore, salivary cortisol could be a useful marker for assessing and managing body weight and CVD risk factors in obese patients. Copyright © 2012 Elsevier Inc. All rights reserved.

  17. A clinical pharmacokinetic microdosing study of docetaxel with Japanese patients with cancer.

    Whether microdosing studies can be used to evaluate the human pharmacokinetics of new anticancer drugs remains unclear. The disposition of docetaxel in cancer patients is linear in terms of dose proportionality. We examined whether the pharmacokinetics of docetaxel in a clinically relevant therapeutic dose could be predicted from the pharmacokinetics of a microdose of docetaxel in Japanese patients with cancer. A microdose of docetaxel (100 μg/patient) was given by 5-min intravenous infusion on day 1, followed by a therapeutic dose of docetaxel (60-75 mg m(-2)), given by 1-h intravenous infusion on day 8. Plasma docetaxel was analyzed by liquid chromatography-tandem mass spectrometry. A two-compartment pharmacokinetic model was used to calculate the area under the plasma concentration-time curve from time 0 to infinity (AUC0-inf). Nine patients received both a microdose and therapeutic dose of docetaxel. The AUC0-inf after microdosing was 3640 ± 1150 ng h L(-1), while that after therapeutic dosing adjusted to 100 mg/patient was 2230 ± 757 µg h L(-1). The ratio of docetaxel clearance in therapeutic dose to that in microdose was 1.8 (P = 0.0041). Plasma α1-acid glycoprotein concentrations negatively correlated with docetaxel clearance at therapeutic dose, whereas the trend was weak at microdose. Docetaxel clearance showed marginal nonlinearity between microdose and therapeutic dose, presumably because of saturation of plasma protein binding; however, the magnitude was within twofold, allowing practically acceptable extrapolation.

  18. Relationship between plasma dabigatran concentration and activated partial thromboplastin time in Japanese patients with non-valvular atrial fibrillation

    Daiki Shimomura

    2015-08-01

    Conclusions: There was a significant correlation between plasma dabigatran concentrations and aPTT. Additionally, in daily clinical practice in Japan, plasma dabigatran concentrations and aPTT reached a peak in the 4-h post administration range. Considering the pharmacokinetics of dabigatran, aPTT can be used as an index for risk screening for excess dabigatran concentrations in Japanese patients with NVAF.

    The purpose of this study was to explore the factors related to earthquake preparedness in Japanese hemodialysis patients. We focused on three aspects of the related factors: health condition factors, social factors, and the experience of disasters. A mail survey of all the members of the Japan Association of Kidney Disease Patients in three Japanese prefectures (N = 4085) was conducted in March, 2013. We obtained 1841 valid responses for analysis. The health factors covered were: activities of daily living (ADL), mental distress, primary renal diseases, and the duration of dialysis. The social factors were: socioeconomic status, family structure, informational social support, and the provision of information regarding earthquake preparedness from dialysis facilities. The results show that the average percentage of participants that had met each criterion of earthquake preparedness in 2013 was 53%. Hemodialysis patients without disabled ADL, without mental distress, and requiring longer periods of dialysis, were likely to meet more of the earthquake preparedness criteria. Hemodialysis patients who had received informational social support from family or friends, had lived with spouse and children in comparison to living alone, and had obtained information regarding earthquake preparedness from dialysis facilities, were also likely to meet more of the earthquake preparedness criteria. © 2017 International Society for Apheresis, Japanese Society for Apheresis, and Japanese Society for Dialysis Therapy.

    Evaluation of mortality trends in dialysis patients is important for improving their prognoses. The present study aimed to examine temporal trends in deaths (all-cause, cardiovascular, noncardiovascular and the five leading causes) among Japanese dialysis patients. Mortality data were extracted from the Japanese Society of Dialysis Therapy registry. Age-standardized mortality rates were calculated by direct standardization against the 2013 dialysis population. The average annual percentage of change (APC) and the corresponding 95% confidence interval (CI) were computed for trends using joinpoint regression analysis. A total of 469 324 deaths occurred, of which 25.9% were from cardiac failure, 17.5% from infectious disease, 10.2% from cerebrovascular disorders, 8.6% from malignant tumors and 5.6% from cardiac infarction. The joinpoint trend for all-cause mortality decreased significantly, by -3.7% (95% CI -4.2 to -3.2) per year from 1988 through 2000, then decreased more gradually, by -1.4% (95% CI -1.7 to -1.2) per year during 2000-13. The improved mortality rates were mainly due to decreased deaths from cardiovascular disease, with mortality rates due to noncardiovascular disease outnumbering those of cardiovascular disease in the last decade. Among the top five causes of death, cardiac failure has shown a marked decrease in mortality rate. However, the rates due to infectious disease have remained stable during the study period [APC 0.1 (95% CI -0.2-0.3)]. Significant progress has been made, particularly with regard to the decrease in age-standardized mortality rates. The risk of cardiovascular death has decreased, while the risk of death from infection has remained unchanged for 25 years. © The Author 2016.

    Full Text Available Functional outcomes in individuals with schizophrenia suggest recovery of cognitive, everyday, and social functioning. Specifically improvement of work status is considered to be most important for their independent living and self-efficacy. The main purposes of the present study were 1 to identify which outcome factors predict occupational functioning, quantified as work hours, and 2 to provide cut-offs on the scales for those factors to attain better work status. Forty-five Japanese patients with schizophrenia and 111 healthy controls entered the study. Cognition, capacity for everyday activities, and social functioning were assessed by the Japanese versions of the MATRICS Cognitive Consensus Battery (MCCB, the UCSD Performance-based Skills Assessment-Brief (UPSA-B, and the Social Functioning Scale Individuals’ version modified for the MATRICS-PASS (Modified SFS for PASS, respectively. Potential factors for work outcome were estimated by multiple linear regression analyses (predicting work hours directly and a multiple logistic regression analyses (predicting dichotomized work status based on work hours. ROC curve analyses were performed to determine cut-off points for differentiating between the better- and poor work status. The results showed that a cognitive component, comprising visual/verbal learning and emotional management, and a social functioning component, comprising independent living and vocational functioning, were potential factors for predicting work hours/status. Cut-off points obtained in ROC analyses indicated that 60–70% achievements on the measures of those factors were expected to maintain the better work status. Our findings suggest that improvement on specific aspects of cognitive and social functioning are important for work outcome in patients with schizophrenia.

    The aim of this study was to investigate real-world treatment patterns for use of golimumab and concomitant medications in Japanese patients with rheumatoid arthritis. This study was a post hoc retrospective analysis from post-marketing surveillance data on 2350 Japanese patients with moderate/severe rheumatoid arthritis who received golimumab for 24 weeks. The study population was divided based on initiation treatment or dose adjustment patterns with golimumab, methotrexate, or oral glucocorticoids. Logistic regression analysis revealed that the baseline factors associated with administration of golimumab (100 mg) were higher body weight, failure of prior biological therapy (bio-failure), no previous methotrexate use, and respiratory disease, while previous methotrexate use and absence of renal impairment or respiratory disease were associated with concomitant methotrexate therapy, and previous glucocorticoid use was associated with concomitant glucocorticoid therapy. The following associations were identified with regard to dose adjustment during treatment: bio-failure, no previous methotrexate use, previous csDMARDs use, presence of respiratory disease, allergy history, and higher CRP for golimumab dose escalation; shorter disease duration, previous GC, and no previous methotrexate use for methotrexate dose escalation; no prior biological therapy and renal impairment for methotrexate dose reduction; no previous GC use for glucocorticoid dose escalation; and absence of Steinbrocker's stage II/III/IV, absence of Steinbrocker's class II, no bio-failure, and no previous csDMARDs use for glucocorticoid dose reduction. This study revealed that various baseline factors were associated with initiation of treatment and dose adjustment of golimumab, methotrexate, or oral glucocorticoids, reflecting both the treatment strategies of physicians for improving RA symptoms and/or reducing adverse events.

    The severity of impaired fatty acid utilization in the myocardium can predict cardiac death in asymptomatic patients on hemodialysis. However, interpretive variability and its impact on the prognostic value of myocardial fatty acid imaging are unknown. A total of 677 patients who received hemodialysis for ≥ 20 years and had one or more cardiovascular risk factors underwent (123)I-labeled β-methyl iodophenyl-pentadecanoic acid (BMIPP) single-photon emission computed tomography (SPECT) at 48 hospitals across Japan. SPECT images were interpreted by experts at the nuclear core laboratory and by readers with varying skill levels at clinical centers, based on the standard 17-segment model and 5-point scoring systems, independently. The κ values only reached fair agreement both for overall impression (κ=0.298, normal vs. abnormal) and for categorical impression (κ=0.244, normal vs. mildly abnormal vs. severely abnormal). The normalcy rate was lower in readers at the clinical centers (60.9%) than in experts (69.9%). In contrast to the results assessed by experts, a Kaplan-Meier analysis based on the interpretation by readers at the clinical centers failed to distinguish the risk of events in patients with normal scans from that of patients with mildly abnormal scans. Considerable variability and its impact on prognostic value were observed in the visual interpretation of BMIPP SPECT images between experts and readers at the clinical centers.

  5. Comparative analysis of the diagnostic and prognostic value of exercise ECG and thallium-201 scintigraphic markers of myocardial ischemia in asymptomatic and symptomatic patients

    Gibson, R.S.

    1989-01-01

    A considerable amount of data now exists that indicates that exercise ECG--due to its suboptimal sensitivity and specificity--has limited diagnostic and prognostic value in asymptomatic subjects, patients with chest pain of unclear etiology or those with chronic stable angina pectoris, and in patients recovering from acute myocardial infarction. Because of this and the well-recognized advantages of thallium-201 scintigraphy, there appears to be a strong rationale for recommending exercise perfusion imaging, rather than exercise ECG alone, as the preferred method for detecting CAD and staging its severity. This recommendation seems justified given the fact that (1) thallium-201 scintigraphy is far more sensitive and specific in detecting myocardial ischemia than exercise testing; (2) unlike stress ECG, thallium-201 scintigraphy can localize ischemia to a specific area of areas subtended by a specific coronary artery; and (3) thallium-201 scintigraphy has been shown to be more reliable to risk stratification of individual patients than exercise testing alone. The more optimal prognostic efficiency of thallium-201 scintigraphy is due, in part, to the fact that the error rate in falsely classifying patients as low-risk is substantially and significantly smaller with thallium-201 scintigraphy than with stress ECG. 52 references

    The efficiency of prophylactic antiarrhythmic treatment with amiodarone in reducing 1-year mortality in patients with reduced left ventricular ejection fraction ( < 35%) and asymptomatic ventricular arrhythmias (Lown classes 2 and 4) was investigated in a prospective, multicenter, randomized, controlled study. Among 127 patients who entered the study, 61 were assigned to no antiarrhythmic therapy (control group [CG] and 66 to amiodarone treatment (amiodarone group [AG]). Amiodarone was administered at a dosage of 800 mg/day for 2 weeks followed by 400 mg/day thereafter. A 12-month follow-up was completed for 106 patients (57 in the AG and 49 in the CG). Amiodarone reduced the overall mortality rate, which was 10.5% in the AG versus 28.6% in the CG (odds ratio [OR] 0.29; 95% confidence interval [CI] 0.10 to 0.84; log-rank test 0.02) and sudden death rate, which was 7.0% in the AG versus 20.4% in the CG (OR 0.29; 95% CI 0.08 to 1.00; log-rank test 0.04). Side effects were rare, and in only three patients did amiodarone treatment have to be discontinued.

    The objectives of this study are to assess the risk of asymptomatic cranial neuropathy among patients with systemic lupus erythematosus (SLE) and find any association with disease activity and antiribosomal P antibodies. This study is a case-control study including 60 female patients and 30 healthy female controls. Disease activity was measured with the SLE disease activity index (SLEDAI). All patients were evaluated using evoked potentials, blink reflex, and levels of antiribosomal P antibodies. Patients with abnormal electrophysiological parameters had significantly higher levels of antiribosomal P antibodies (P = 0.034) and secondary antiphospholipid syndrome (P = 0.044). Antiribosomal P antibodies (odds ratio 5.4, 95 % confidence interval 1.002-1.03, P = 0.002) and presence of anti-DNA antibodies (odds ratio 1.01, 95 % confidence interval 1.2-24.8, P = 0.032) were independent risk factors for the presence of the abnormal electrophysiological parameters. Disease duration was positively correlated with wave 1 of the auditory brain reflex (P < 0.001) and a latency of the evoked blink reflex (component R1, P = 0.013). SLEDAI scores were positively correlated with latencies of the visually evoked potential (P100, P = 0.02), wave 1 of the auditory brain reflex (P < 0.001), and a latency of the evoked blink reflex (R2c, P = 0.005). Steroid dosage was negatively correlated with P100 latencies (P = 0.042) and components of the evoked blink reflex (R1, P = 0.042; R2i, P = 0.041; R2c, P < 0.001). Because abnormalities in the visually evoked potential and blink reflex were associated with antiribosomal P antibodies, they can be useful for detecting asymptomatic cranial neuropathy. Further studies on large number of patients should be done to determine any association.

    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 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 gigantism.

    Dual oxidase 2 (DUOX2) mutations are a cause of dyshormonogenesis (DH) and have been identified in patients with permanent congenital hypothyroidism (PH) and with transient hypothyroidism (TH). We aimed to elucidate the prevalence and phenotypical variations of DUOX2 mutations. Forty-eight Japanese DH patients were enroled and analysed for sequence variants of DUOX2, DUOXA2, and TPO using polymerase chain reaction-amplified direct sequencing. Fourteen sequence variants of DUOX2, including 10 novel variants, were identified in 11 patients. DUOX2 variants were more prevalent (11/48, 22.9%) than TPO (3/48, 6.3%) (p=0.020). The prevalence of DUOX2 variants in TH was slightly, but not significantly, higher than in PH. Furthermore, one patient had digenic heterozygous sequence variants of both DUOX2 and TPO. Our results suggest that DUOX2 mutations might be the most common cause of both PH and TH, and that phenotypes of these mutations might be milder than those of other causes.

    Full Text Available 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.

    2018-05-01

    We conducted a post-marketing surveillance to evaluate the safety and efficacy of TKN732, approved as "filgrastim biosimilar 2", in Japanese patients who developed neutropenia in the course of cancer chemotherapy or hematopoietic stem cell transplantation. A total of 653 patients were registered during the 2-year enrollment period starting from May 2013, and 627 and 614 patients were eligible for safety and efficacy analyses of the G-CSF biosimilar, respectively. Forty-three adverse drug reactions were reported in 33 patients (5.26%). Back pain was most frequently observed and reported in 20 patients (3.19%), followed by pyrexia (1.28%) and bone pain (0.96%). Risk factors for adverse reactions identified by logistic regression analyses were younger age, presence of past medical history, and lower total dose at the onset of adverse reactions. Among the 576 cancer patients who developed Grade 2-4 neutropenia after chemotherapy, recovery to Grade 1/0 was reported in 553 patients (96%) following filgrastim biosimilar 2 treatment. The median duration of neutrophil counts below 1500/μL was 5 days. In addition, all 11 patients who underwent hematopoietic stem cell transplantation had good responses to filgrastim biosimilar 2. In conclusion, this study showed that filgrastim biosimilar 2 has a similar safety profile and comparable effects to the original G-CSF product in the real world clinical setting.

    Relevance of posture assessment has been reported in case of spine disorders. This study explores the interest in quantifying posture using 3D reconstruction from biplanar X-rays in free standing position and a force plate. 93 patients consulting for spine disorders were divided (‘3D deformity’, ‘sagittal imbalance’ and ‘mild deformity’) and compared with 23 asymptomatic volunteers. Registration of the gravity line (GL) in reconstruction yielded transversal position of the center of acoustic meati (CAM) T1, T4, T9, L3, S1 and hip axis (HA) with regard to GL. Transversal position of CAM and L3 appeared as relevant parameters to discriminate patients from volunteers. Sagittal inclination of the axis linking the CAM to HA was correlated with position of the CAM to GL (r = 0.92 for patients). In conclusion, observing posture in 3D with regard to GL provides clinical relevant information. CAM-HA inclination may improve postural evaluation without force plate. PMID:20035359

  15. Frequency of asymptomatic pulmonary emboli (PE) in patients with a proximal profound veinal thrombosis (PVT) of inferior limbs during the FRAXODI study

    1997-01-01

    FRAXODI, an European multi-center program (n=70), allowed to compare the efficiency of Fraxiparin (20 500 UI AXa/mL) once a day with the conventional treatment by Fraxiparin (10 250 UI AXa/mL) twice a day by sub-cutaneous injection in patients with a PVT of inferior limbs without clinical signs of PE. A pulmonary scintigraphy has been performed at registration in 622 patients (delay ≤ 48 h): a sole perfusion with at least 4 incidences of which 2 were posterior oblique incidences or coupled to a ventilation scintigraphy (Xe-133, Kr-81 or aerosols) in 379 patients. Three diagnostic categories were defined: no PE in case of normal examination or under-segmentary perfusion anomalies (≤ 3); high probability (HP) of PE if at least a defect of normally ventilated segmentary perfusion existed; non-contributing examination in all the other cases. On the ensemble of the group, 367 patients have had at least a defect of segmentary perfusion, 296 patients had two or more. One hundred and forty one patients have had solely defects of sub-segmentary perfusion; 77 patients have had 3 or less then 3. One hundred and fourteen patients have had a normal examination. In the sub-group of ventilation scintigraphy, 235 patients have had at least one defect of segmentary perfusion, 88 patients have had defects of sub-segmentary perfusion and 56 patients have had a normal examination. The diagnosis analysis showed that 42% of patients have had a HP scintigraphy, 30% a non-contributive scintigraphy and the PE could be eliminated in 27% of patients. These results: 1 - demonstrated the extreme frequency of HP aspects of PE in patients afflicted with PVT; 2 - allowed estimating in this patients, as a function of the results of the PIOPED study, the frequency of asymptomatic PE in more then 50%; 3 - allowed recommending in the systematic practice a perfusion scintigraphy in case of PVT without clinical signs of PE providing the over-estimation of secondary PE occurrence during the

  16. Providing written information increases patient satisfaction: a web-based questionnaire survey of Japanese cancer survivors.

    The Institute of Medicine (IOM) of the United States recommends that all cancer survivors be provided with a survivorship care plan (SCP), which includes a patient treatment summary and a follow-up care plan. However, SCPs have not been widely adopted in Japan. To provide basic data necessary for implementing SCPs in Japan, we aimed to investigate the forms of clinical and survivorship-related information that Japanese cancer survivors receive from their healthcare providers, and to examine whether written information increases their satisfaction. We performed a cross-sectional online survey of cancer survivors who underwent acute cancer treatment and had at least one follow-up with a physician in the past year. Cancer survivors provided the elements and forms (verbally and/or written) of information they received, as well as the degree of satisfaction with the information provided. Responses were obtained from 545 cancer survivors. Information elements such as surgical procedure (98.3%), surgical outcome (98.1%), and names of administered chemotherapy agents (97.8%) were commonly provided, whereas mental care resources and providers (29.7%), effects on marital relationship and sexual health (35.7%), and effects on fertility (43.4%) were less common. A large proportion of cancer survivors received verbal information only. For 18 of 20 elements, except for effects on fertility and duration of hormonal therapy, satisfaction was significantly higher when both forms of information were provided (P information can better meet the needs of Japanese cancer survivors. © The Author 2017.

    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.

    It has become important to standardize the methods of Ki-67 evaluation in breast cancer patients, especially those used in the interpretation and scoring of immunoreactivity. Therefore, in this study, we examined the Ki-67 immunoreactivity of breast cancer surgical specimens processed and stained in the same manner in one single Japanese institution by counting nuclear immunoreactivity in the same fashion. We examined 408 Japanese breast cancers with invasive ductal carcinoma and studied the correlation between Ki-67 labeling index and ER/HER2 status and histological grade of breast cancer. We also analyzed overall survival (OS) and disease-free survival (DFS) of these patients according to individual Ki-67 labeling index. There were statistically significant differences of Ki-67 labeling index between ER positive/HER2 negative and ER positive/HER2 positive, ER negative/HER2 positive or ER negative/HER2 negative, and ER positive/HER2 positive and ER negative/HER2 negative groups (all P < 0.001). There were also statistically significant differences of Ki-67 labeling index among each histological grade (P < 0.001, respectively). As for multivariate analyses, Ki-67 labeling index was strongly associated with OS (HR 39.12, P = 0.031) and DFS (HR 10.85, P = 0.011) in ER positive and HER2 negative breast cancer patients. In addition, a statistically significant difference was noted between classical luminal A group and "20 % luminal A" in DFS (P = 0.039) but not between classical luminal A group and "25 % luminal A" (P = 0.105). A significant positive correlation was detected between Ki-67 labeling index and ER/HER2 status and histological grades of the cases examined in our study. The suggested optimal cutoff point of Ki-67 labeling index is between 20 and 25 % in ER positive and HER2 negative breast cancer patients.

Patients with NTG who initiated tafluprost treatment were registered and prospectively observed for 2–3 years to investigate its effectiveness on visual field progression and intraocular pressure (IOP and safety in Japan. Visual field progression was evaluated using mean deviation (MD slopes in a visual field analysis set that comprised patients with reliable Humphrey visual fields taken at 5 or more time points throughout the 2–3 years.Results: Of the 1,454 patients registered from 160 medical institutions, 1,353 were set for safety analysis and 416 were set for visual field analysis. Due to insufficient effectiveness or safety reasons 194 patients discontinued tafluprost, and 388 patients discontinued tafluprost due to being lost to follow-up or another reason. The MD slopes were −0.09±0.85 dB/year in the entire visual field analysis set, -0.02±0.80 dB/year in naïve monotherapy patients, −0.07±0.68 dB/year in switching monotherapy patients, and −0.32±1.04 dB/year in concomitant therapy patients. In naïve monotherapy, a significant difference in MD slopes was observed between patients with an IOP reduction of 10% or higher (0.11±0.73 dB/year vs patients with an IOP reduction of <10% (−0.22±0.87 dB/year. Significant differences were also observed in the subset analyses when the patients were divided by both MD and IOP at baseline, and presence of vitreoretinal concomitant disease. The adverse reactions were observed in 9.53% patients without any serious

    To investigate the pathophysiology of functional heartburn (FH) in Japanese patients. A total of 111 patients with proton pump inhibitor (PPI)-refractory non-erosive gastroesophageal reflux disease underwent intraesophageal pressure testing and 24-h multichannel intraluminal impedance-pH (24MII-pH) testing. The patients also completed several questionnaires while they were receiving the PPI treatment, including the questionnaire for the diagnosis of reflux disease (QUEST), the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG), the gastrointestinal symptoms rating scale (GSRS), SF-36, and the Cornell Medical Index (CMI). The subjects were classified into FH and endoscopy-negative reflux disease (ENRD) groups based on the Rome III criteria. Thirty-three patients with esophageal motility disorder were excluded from this study, while 22 patients with abnormal esophageal acid exposure time (pH-POS) and 34 with hypersensitive esophagus (HE) were included in the ENRD group. The FH group included 22 patients with no reflux involvement. Sex, age, and body mass index did not differ significantly between the groups. The mean SF-36 values were < 50 (normal) for all scales in these groups, with no significant differences. The GSRS scores in these groups were not different and showed overlap with other gastrointestinal symptoms. The QUEST and the FSSG scores did not differ significantly between the groups. Neuroticism was diagnosed using the CMI questionnaire in 17 of the 78 included subjects within the pH-POS (n = 4), HE (n = 8), and FH (n = 5) groups, with no significant differences. Clinical characteristics of the FH and PPI-refractory ENRD groups were similar. Therefore, esophageal function should be examined via manometry and 24MII-pH testing to differentiate between them.

    In Japan, Meiji 817-B (M817-B), a powdered ketogenic milk, has been available since the ketogenic diet was introduced to infants and tube-fed children with medication-resistant epilepsy in the 1980s. We retrospectively evaluated the efficacy, tolerability, and side effects of the ketogenic diet using M817-B as the main source of daily food intake for patients with epilepsy by sending questionnaires to the members of a subcommittee of the Japan Epilepsy Society that focuses on the proper use of M817-B. A total of 42 patients were enrolled. Age at the initiation of the diet therapy ranged from 3 to 244 months (median, 32.5 months). Thirty-four patients were fed via tube, and the remaining 8 were fed orally. About 93% of patients were able to continue the diet for 1 month, 74% for 3 months, and 64% for 6 months. The median period of continuation was 16 months. One patient was able to continue as long as 7 years. The ketogenic ratio was maintained at about 3.0. The seizure-free rate and responder (>50% seizure reduction) rate were about 10% and 30-40%, respectively during the 12 months on the diet. Mean serum beta-hydroxybutyrate increased to almost 4 mM at 1 month and was maintained during the diet period. Side effects, which required discontinuation of the diet therapy, occurred in 11 of 42 patients and included hypertonia, weight loss, vomiting, hypoglycemia, metabolic acidosis, and hypokalemia. M817-B could be used long-term with demonstrated efficacy in seizure reduction, although there are some side effects that may require cessation of the diet therapy.

    Patients' high adherence to medication is indispensable for the management of skin diseases including atopic dermatitis. We previously showed poor medication adherence in Japanese dermatological patients. This study was conducted to determine the level of adherence to oral or topical medication in Japanese patients with atopic dermatitis, attempting to characterize the socioeconomic status of those patients with poor adherence. A web questionnaire survey on demographic data as well as adherence level was conducted on patients registered in the monitoring system. Adherence level was assessed with Morisky Medication Adherence Scale-8 (MMAS-8). Among a total of 3096 respondents with dermatological disorders, data of 1327 subjects with atopic dermatitis were extracted and analyzed. More than 80% of subjects felt that both oral and topical medications were safe and efficacious, while less than 60% of them were satisfied with their treatment. Levels of adherence to oral and topical treatments were evaluated with MMAS-8, giving scores of 4.6 and 4.2, respectively. Demographic factors such as gender, marital status, state of employment, alcohol consumption, frequency of hospital visits, and experience of drug effectiveness had a significant impact on the degree of adherence to treatment. Medication adherence level in Japanese subjects with atopic dermatitis was relatively low compared with that of other chronic diseases. Our survey has characterized patients with poor adherence, who are good targets for interventions to maximize potentially limited healthcare resources. Copyright © 2015 Z.

  5. 99mTc-MIBI/123I-Na subtraction scanning for localized parathyroid adenoma in patients with asymptomatic/mild primary hyperparathyroidism

    Tanaka, Yuji; Funahashi, Hiroomi; Imai, Tsuneo

    1996-01-01

    Primary hyperparathyroidism is most commonly detected as a mild elevation of the serum calcium concentration. In the present study, the utility of 99m Tc-methoxyisobutylisonitrile (MIBI) imaging before initial surgery was evaluated for localizing abnormal parathyroid glands in patients with asymptomatic and mild primary hyperparathyroidism. The results were compared with those of thallium-technetium subtraction scanning (TTSS). 99m Tc-MIBI/ 123 I-Na subtraction scanning was performed in 11 patients, and TTSS was performed in 10 of them. The sensitivity was 100% and the positive predictive value was 92% for 99m Tc-MIBI/ 123 I-Na, while the sensitivity was 50% and the positive predictive value was 100% for TTSS. The smallest gland detected weighed 85 mg in 99m Tc-MIBI/ 123 I-Na, and 570 mg in TTSS. There was a difference between the median weight of adenomas which were detected by 99m Tc-MIBI/ 123 I-Na (754 mg), and those which were detected by TTSS (1,195 mg). These results suggest that TTSS parathyroid scintigraphy could give way to 99m Tc-MIBI/ 123 I-Na parathyroid scintigraphy for improved detection of low-weight abnormal parathyroid glands. (author)

    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 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.

  9. Open Heart Surgery Does Not Increase the Incidence of Ipsilateral Ischemic Stroke in Patients with Asymptomatic Severe Carotid Stenosis.

    Castaldo, John E; Yacoub, Hussam A; Li, Yuebing; Kincaid, Hope; Jenny, Donna

    2017-10-01

    We evaluated the incidence of perioperative stroke following the institution's 2007 practice change of discontinuing combined carotid endarterectomy and open heart surgery (OHS) for patients with severe carotid stenosis. In this retrospective cohort study, we compared 113 patients undergoing coronary artery bypass grafting, aortic valve replacement, or both from 2007 to 2011 with data collected from 2001 to 2006 from a similar group of patients. Our aim was to assess whether the practice change led to a greater incidence of stroke. A total of 7350 consecutive patients undergoing OHS during the specified time period were screened. Of these, 3030 had OHS between 2007 and 2011 but none were combined with carotid artery surgery (new cohort). The remaining 4320 had OHS before 2007 and 44 had combined procedures (old cohort). Of patients undergoing OHS during the 10-year period of observation, 230 had severe (>80%) carotid stenosis. In the old cohort (before 2007), carotid stenosis was associated with perioperative stroke in 2.5% of cases. None of the 113 patients having cardiac procedures after 2007 received combined carotid artery surgery; only 1 of these patients harboring severe carotid stenosis had an ischemic stroke (.9%) during the perioperative period. The difference in stroke incidence between the 2 cohorts was statistically significant (P = .002). The incidence of stroke in patients with severe carotid artery stenosis undergoing OHS was lower after combined surgery was discontinued. Combined carotid and OHS itself seems to be an important risk factor for stroke. Copyright © 2017 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    2016-06-01

    The aim of this study was to evaluate the incidence of prostatic calcification and prostatitis NIH category IV in patients with obstructive BPH. Ninety-six patients with obstructive BPH who had undergone transurethral electroresection of the prostate gland were evaluated. In accordance with a preoperative transrectal ultrasound examination, patients were divided into one group with prostatic calcification (N.=31) and one without (N.=65). Prostatitis NIH category IV was classified according to the grading system by Irani. Correlations between the incidence of prostatic calcification, histological prostatitis, PSA, uric acid, cholesterol, triglycerides, CRP, IPSS, IIEF-25, and NIC-CPSI were analyzed. A stone analysis of prostatic calcification was performed using X-ray powder diffraction. Sixty-nine (71.9%) patients had NIH category IV prostatitis, accounting for 83.9% of those with prostatic calcification versus 66.1% of those without (Pprostatic calcification and the severity of inflammation (Pprostatic calcifications were elevated levels of uric acid. Such patients were 1.4times more likely of having calcifications in the prostate gland (OR=1.4, Pprostatic calcification. These were significantly more common in patients with NIH category IV prostatitis.

    Mendese, Gary; Grande, Donald

    2013-09-01

    The authors report an unusual case of Rocky Mountain spotted fever that presented as an asymptomatic petechial eruption on the lower legs. Rocky Mountain spotted fever is rare in New England and, as such, is typically not on the differential diagnosis when presented with such patients. What began as an asymptomatic eruption progressed to more classic signs of the disease, including a positive Rocky Mountain spotted fever titer. The patient was successfully treated with doxycydine and within a short period of time, was completely back at baseline.

    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.

    Full Text Available BACKGROUND India, with a population greater than 1.1 billion, has the dubious distinction of having a larger number of people with diabetes than any other country in the world. It was estimated in the year. 2000 that there are 32 million diabetes patients. Diabetic foot ulcers will complicate the disease in more than 15% of these people during their life time. Foot ulcers precede more than 80% of non-traumatic lower limb amputation. Individuals with diabetes had a tenfold higher overall amputation prevalence than did people without diabetes, 2.8% versus 0.29%. MATERIALS AND METHODS A Cross sectional study was done in the department of general surgery, Government Medical College Kottayam and Diabetic Clinic, Kottayam Medical College, from April 1, 2013 to October 1, 2013. RESULTS Out of 150 patients studied 83 were males and 67 were females and 95 patients (63.3% had POVD Statically significant association was found between POVD and age, history of hypertension, hyperlipidaemia, smoking, alcoholism, duration of diabetes mellitus and family history of hypertension/diabetes and hyperlipidaemia. Sensitivity and specificity of Pulse Oximetry in diagnosing POVD is 80% and 92.7% respectively. Sensitivity and specificity of ABPI in diagnosing POVD is 77.9% and 89.1% respectively. CONCLUSION Pulse Oximetry is an accurate and efficient screening tool for POVD in patients with diabetes mellitus. It can be incorporated to regular outpatient visits of Diabetes patients for early detection of POVD.

    To evaluate the safety of ramelteon, a highly selective MT₁/MT₂ melatonin receptor agonist, during 24 weeks' treatment of Japanese patients with chronic insomnia. In a single-blind, flexible-titration, multicenter study incorporating placebo run-in and run-out periods, 190 adults with chronic insomnia received ramelteon 4 or 8 mg, titrated up to 16 mg if necessary, for 24 weeks. Primary endpoints included adverse events, residual effects, rebound insomnia, withdrawal symptoms, and dependence. Secondary endpoints included subjective sleep latency and total sleep time. Drug-related adverse events occurred in 11.6% of patients. No clinically important changes occurred in biochemical, hematological or endocrine parameters. There were no signs of next-day residual effect, rebound insomnia, withdrawal symptoms or dependence. Mean subjective sleep latency decreased significantly, and total sleep time increased significantly; both reached a plateau by week 20 and were sustained thereafter (Pinsomnia and did not cause deterioration of efficacy, residual effects, rebound insomnia, withdrawal symptoms, or dependence after 24 weeks' treatment.

    1990-10-01

    The role of the distal stomach in gastric emptying was studied. Ten patients with proximal gastric vagotomy (PV) and 10 age-matched patients with Roux-en-Y gastro-jejunostomy (R-Y) were compared with 10 healthy controls. Gastric emptying of solids and liquids was determined by the use of Tc-99m SC scrambled eggs and In-111 DTPA. In PV, gastric emptying of both solids and liquids was delayed; the prolongation with solids was mainly accounted for by an abnormal lag phase. In R-Y patients, no lag phase was observed, and the solid emptying curve pattern was characterized by early rapid emptying followed by very slow emptying. Both the solid and liquid phases were prolonged. The lag phase is affected by proximal vagotomy and is mainly determined by the distal stomach, which appears to be essential for normal emptying.

    1990-01-01

    The relationship between intestinal permeability to an oral dose (100 mu Ci) of [51CR]EDTA and the inflammatory activity of Crohn's disease was studied in 63 adult patients (32 unresected and 31 resected) who underwent 162 evaluations. The results of the [51CR]EDTA test were compared with the serum levels of the acute-phase reactant proteins (APRP) and with the result of the [111In]leukocyte scanning, respectively, as an indirect and direct method to assess intestinal inflammation. In a group of healthy adult controls, the upper normal value for the 24-hr urinary [51CR]EDTA excretion was 3.61 (97.5% percentile) and the mean coefficient of variation was 21%. Sensitivity and specificity of the [51CR]EDTA test in identifying active inflammation expressed by increased serum levels of APRP were, respectively, 97% and 54% in the unresected group and 68% and 52% in the resected group of patients. The low specificity of the test was due to the presence of increased [51CR]EDTA urinary excretion in about half the cases with normal serum levels of APRP. The [111In]leukocyte scanning was performed in a subgroup of 11 patients (three unresected and eight resected) with normal serum levels of APRP, six with increased and five with normal [51CR]EDTA urinary excretion. All six patients with increased intestinal permeability had a positive 111In image of mild to moderate degree of activity. A positive 111In scan was present in two of the five patients with normal permeability; these were two resected patients

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

    Full Text Available Abstract 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

    Once lung cancer is detected due to clinical symptoms or by being visible on chest X-ray, it is usually high stage and non-operable. In order to improve mortality rates in lung cancer, low-dose CT (LDCT) screening of “high risk” individuals is gaining popularity. However, the rate of malignancy in LDCT detected sub-centimetre lung nodules is not clear. We aimed to analyze surgically resected specimens in this patient group to explore cost effectiveness and recommendations for clinical management of these nodules. Our hospital pathology database was searched for sub-centimeter lung nodules detected by LDCT screening which were resected. The patient demographics were collected and the radiologic and pathologic characteristics of those nodules were analyzed. From the records, 44 patients with 46 resected subcentimetre nodules were identified. Patients were selected for surgery based on an irregular shape, growth in size during follow up, family history of lung cancer or personal history of cancer of other sites, previous lung disease, smoking and personal anxiety. Of the 44 patients, 33 were women and the ages ranged from 43 to 76 years (56.75 ± 8.44). All nodules were equal to, or less than 10 mm with a mean diameter of 7.81 ± 1.80 mm (SD). Out of 46 nodules, the pathological diagnoses were: invasive adenocarcinoma (ACa) in 4 (8.7%); adenocarcinoma in situ (AIS) or atypical adenomatous hyperplasia (AAH) in 29 (63%); benign fibrosis/fibrotic scar with inflammation or calcification in 12 (26.1%); an intrapulmonary benign lymph node in 1 (2.2%). Of the ACa, AIS and AAH groups (a total of 31 patients), 77% were women (24 vs. 7). The cancer or pre-cancer nodules (ACa, AIS and AAH) tended to be larger than benign fibrotic scars (P = 0.039). Amongst all characteristics, significant statistical differences were found when the following radiological features were considered: reconstructed nodule shape (P = 0.011), margin (P = 0.003) and ground glass pattern (P = 0

    Full Text Available INTRODUCTION The cardiovascular changes (vascular structure changes, hypertrophy of the left ventricle contribute to both the increased cardiovascular morbidity and the mortality of essential hypertension. Therefore, modern treatment strategies should not only target blood pressure (BP reduction but also normalize cardiovascular structure and function. OBJECTIVE Aim of the study was to determine the effect of the ACE inhibitor Fosinopril on the Intima-media thickness of the common carotid artery and on the left ventricle mass after 9-month treatment of hypertensive patients. METHOD The study included 40 patients with the arterial hypertension and the left ventricle hypertrophy verified by echocardiography. The patients were randomized on A ACE-inhibitor - Fosinopril and 6 without ACE inhibitor - atenolol, and they were followed up 9 months. The groups were not different by age, sex, and metabolic status. Color Duplex ultrasonography of the carotid arteries was performed by Acuson Sequia C236 with high-frequency linear probe of 8 MHz. The Intima-media thickness of the common carotids on the left and the right was measured in diastole at 1.5. cm from the highest point of bifurcation under maximal magnification. Using the same device, the left ventricle mass and other parameters of the left ventricle were determined in M-mode and by means of 2D image. RESULTS After 9 months, BP In both groups Was reduced In similar range (group A: systolic BP from 158 to 137 mmHg, and diastolic BP from 94 to 85 mmHg, and group B; systolic BP from 164 to 137 mmHg, and diastolic BP from 87 to 84 mmHg. The thickness of the intimomedial complex in patients using Fosinopril was decreased by 0.0278 ± 0.03 mm, while in the group of patients that did not use the ACE-inhibitor, it was increased by 0.078 ±0.13 mm. The left ventricle mass in patients using Fosinopril was decreased by 5 grams (312 ± 72 g vs. 307 ± 77 g, while in group B patients, it was increased by 15

    Many radiological signs are known for the diagnosis of idiopathic normal pressure hydrocephalus (iNPH). However, there is little information about these signs in the pre-symptomatic phase. For pathophysiological investigative purposes we conducted a descriptive image analysis study on pre-symptomatic patients. Patients that had contact with either the neurological or neurosurgical department of the university hospital Tuebingen from 2010 through 2016 with magnetic resonance images > 3 years before onset of symptoms, were included. The date of onset and severity of symptoms, date of first imaging and birth date were recorded. Evan's index (EI), width of the third ventricle (3VW), tight high convexity (THC), Sylvian fissure, extent of white matter hyperintensities and aqueductal flow were assessed in images before and around symptom onset. Ten patients were included. In all ten patients the first symptom was gait disturbance. Nine of ten pre-symptomatic images showed classic signs for iNPH. EI showed a significant increase between the pre-symptomatic and symptomatic phase. 3VW showed a trend for increase without significance. THC changed back and forth over time within some patients. In accordance with the scarce literature available, radiological changes are present at least 3 years before onset of iNPH-symptoms. EI seems to be a robust measure for pre-symptomatic radiological changes. Extrapolating the data, the development of iNPH typical changes might be an insidious process and the development of THC might be a variable and non-linear process. Further studies with larger sample sizes are necessary to put these findings into the pathophysiological perspective for the development of iNPH.

    Previous reports on the results of treatment for aneurysmal subarachnoid hemorrhage (SAH) have been based only on activities of daily living after discharge, whereas resumption of work has received insufficient attention. Most Japanese work under a lifetime employment system, and it is best for those who have recovered from SAH to return to work for their previous employer. The present study was conducted to determine the extent to which discharged patients who have suffered an SAH resume their former occupations in Japan, focusing on those between 40 and 49 years of age, who usually have a strong desire to return to work. The participants consisted of 193 patients with SAH. Based on the results of telephone interviews or written questionnaires, their work status at 1 year after onset was analyzed. The work resumption rates for patients with Hunt and Kosnik neurological Grades 1 or 2 on admission were higher than for those with Grades 3 or 4 (p = 0.015) and lower for patients with basilar artery aneurysms than for those with aneurysms at other sites (p = 0.028). With regard to premorbid occupation, the work resumption rates were high (80%) for professionals and engineers, many of whom were public servants, or teachers at junior or senior high schools. The resumption rates were also high for primary industry workers (80%), but lowest (20%) for professional drivers (p = 0.04-0.001). The work resumption rate was lower for women than for men (p = 0.01). These findings indicate that resumption of work is determined not only by medical factors, but also by social factors including gender, type of occupation, employment system, and socioeconomic background.

    Arboleda et al. have recently shown that IMAGe (intra-uterine growth restriction, metaphyseal dysplasia, adrenal hypoplasia congenita and genital abnormalities) syndrome is caused by gain-of-function mutations of maternally expressed gene CDKN1C on chromosome 11p15.5. However, there is no other report describing clinical findings in patients with molecularly studied IMAGe syndrome. Here, we report clinical and molecular findings in Japanese patients. We studied a 46,XX patient aged 8·5 years (case 1) and two 46,XY patients aged 16·5 and 15·0 years (cases 2 and 3). Clinical studies revealed not only IMAGe syndrome-compatible phenotypes in cases 1-3, but also hitherto undescribed findings including relative macrocephaly and apparently normal pituitary-gonadal endocrine function in cases 1-3, familial glucocorticoid deficiency (FGD)-like adrenal phenotype and the history of oligohydramnios in case 2, and arachnodactyly in case 3. Sequence analysis of CDKN1C, pyrosequencing-based methylation analysis of KvDMR1 and high-density oligonucleotide array comparative genome hybridization analysis for chromosome 11p15.5 were performed, showing an identical de novo and maternally inherited CDKN1C gain-of-function mutation (p.Asp274Asn) in cases 1 and 2, respectively, and no demonstrable abnormality in case 3. The results of cases 1 and 2 with CDKN1C mutation would argue the following: [1] relative macrocephaly is consistent with maternal expression of CDKN1C in most tissues and biparental expression of CDKN1C in the foetal brain; [2] FGD-like phenotype can result from CDKN1C mutation; and [3] genital abnormalities may primarily be ascribed to placental dysfunction. Furthermore, lack of CDKN1C mutation in case 3 implies genetic heterogeneity in IMAGe syndrome. © 2013 John Wiley & Sons Ltd.

    The present study investigated when and how Japanese people with cleft lip and palate (CL/P) learn that their condition is congenital; the perceived effects of withholding the CL/P diagnosis on patients; and whether the resulting social experience and self-esteem are related. A questionnaire survey was conducted in 71 adults with CL/P recruited through a hospital, a patients' association, and by snowball sampling. The participants became aware of their physical difference in childhood, but many reported difficulty in understanding their condition. Participants reported that their families avoided the topic of diagnosis. Participants who understood their condition during childhood rather than in adulthood were significantly more likely to consider this scenario as positive (p self-esteem were more likely to feel that they received adequate support. It is important to explain the congenital nature of CL/P sufficiently and early. In addition, openness by the family about the diagnosis, rather than avoidance, may improve patients' self-esteem. Sufficient support from family, health care providers, and significant others is needed for patients to develop adequate self-esteem.

    Objective Everolimus, an inhibitor of the mammalian target of rapamycin, has recently demonstrated efficacy and safety in a Phase III, double-blind, randomized trial (RADIANT-3) in 410 patients with low- or intermediate-grade advanced pancreatic neuroendocrine tumours. Everolimus 10 mg/day provided a 2.4-fold improvement compared with placebo in progression-free survival, representing a 65% risk reduction for progression. The purpose of this analysis was to investigate the efficacy and safety of everolimus in the Japanese subgroup enrolled in the RADIANT-3 study. Methods Subgroup analysis of the Japanese patients was performed comparing efficacy and safety between everolimus 10 mg/day orally (n = 23) and matching placebo (n = 17). The primary endpoint was progression-free survival. Safety was evaluated on the basis of the incidence of adverse drug reactions. Results Progression-free survival was significantly prolonged with everolimus compared with placebo. The median progression-free survival was 19.45 months (95% confidence interval, 8.31–not available) with everolimus vs 2.83 months (95% confidence interval, 2.46–8.34) with placebo, resulting in an 81% risk reduction in progression (hazard ratio, 0.19; 95% confidence interval, 0.08–0.48; P< 0.001). Adverse drug reactions occurred in all 23 (100%) Japanese patients receiving everolimus and in 13 (77%) patients receiving placebo; most were grade 1/2 in severity. The most common adverse drug reactions in the everolimus group were rash (n = 20; 87%), stomatitis (n = 17; 74%), infections (n = 15; 65%), nail disorders (n = 12; 52%), epistaxis (n = 10; 44%) and pneumonitis (n = 10; 44%). Conclusions These results support the use of everolimus as a valuable treatment option for Japanese patients with advanced pancreatic neuroendocrine tumours. PMID:22859827

  9. Pneumocystis jirovecii detection in asymptomatic patients: what does its natural history tell us? [version 1; referees: 3 approved

    Alexandre Alanio

    2017-05-01

    Full Text Available Pneumocystis jirovecii is an unusual ascomycetous fungus that can be detected in the lungs of healthy individuals. Transmission from human to human is one of its main characteristics in comparison with other fungi responsible for invasive infections. P. jirovecii is transmitted through the air between healthy individuals, who are considered to be the natural reservoir, at least transiently. In immunocompromised patients, P. jirovecii multiplies, leading to subacute infections and acute life-threatening pneumonia, called Pneumocystis pneumonia [PCP]. PCP is caused by genotypically distinct mixtures of organisms in more than 90% of cases, reinforcing the hypothesis that there is constant inhalation of P. jirovecii from different contacts over time, although reactivation of latent organisms from previous exposures may be possible. Detection of P. jirovecii DNA without any symptoms or related radiological signs has been called “colonization”. This situation could be considered as the result of recent exposure to P. jirovecii that could evolve towards PCP, raising the issue of cotrimoxazole prophylaxis for at-risk quantitative polymerase chain reaction (qPCR-positive immunocompromised patients. The more accurate way to diagnose PCP is the use of real-time quantitative PCR, which prevents amplicon contamination and allows determination of the fungal load that is mandatory to interpret the qPCR results and manage the patient appropriately. The detection of P. jirovecii in respiratory samples of immunocompromised patients should be considered for potential risk of developing PCP. Many challenges still need to be addressed, including a better description of transmission, characterization of organisms present at low level, and prevention of environmental exposure during immunodepression.

  10. Cytokine profile and proviral load among Japanese immigrants and non-Japanese infected with HTLV-1 in a non-endemic area of Brazil.

    João Américo Domingos

    Full Text Available The lifetime risk of HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP development differs among ethnic groups. To better understand these differences, this prospective cohort study was conducted to investigate the cytokine profile and the HTLV-1 proviral load (PVL in Japanese and non-Japanese populations with HAM/TSP and asymptomatic carriers (ACs. The serum IL-2, IL-4, IL-6, IL-10, IL-17, TNF-α, and IFN-γ levels were quantified using the Cytometric Bead Array in 40 HTLV-1-infected patients (11 HAM/TSP and 29 ACs and 18 healthy controls (HCs in Brazil. Among ACs, 15 were Japanese descendants and 14 were non-Japanese. Of 11 patients with HAM/TSP, only one was a Japanese descendant. The HTLV-1 PVL was quantified by real-time PCR. The HTLV-1 PVL was 2.7-fold higher in HAM/TSP patients than ACs. Regardless of the clinical outcome, the PVL was significantly higher in patients younger than 60 years than older patients. The HAM/TSP and ACs had higher IL-10 serum concentrations than that of HCs. The ACs also showed higher IL-6 serum levels than those of HCs. According to age, the IL-10 and IL-6 levels were higher in ACs non-Japanese patients older than 60 years. HAM/TSP patients showed a positive correlation between IL-6 and IL-17 and a negative correlation between the PVL and IL-17 and IFN-γ. In the all ACs, a significant positive correlation was observed between IL-2 and IL-17 and a negative correlation was detected between IL-10 and TNF-α. Only 6.25% of the Japanese patients were symptomatic carriers, compared with 41.67% of the non-Japanese patients. In conclusion, this study showed that high levels of HTLV-1 PVL was intrinsicaly associated with the development of HAM/TSP. A higher HTLV-1 PVL and IL10 levels found in non-Japanese ACs over 60 years old, which compared with the Japanese group depicts that the ethnic background may interfere in the host immune status. More researches also need to be undertaken regarding the host

    The objectives of this study were to describe the frequency of and to determine predictive factors associated with Radiation Therapy Oncology Group urinary toxicity in prostate brachytherapy patients. From January 2004 to April 2011, 466 consecutive Japanese patients underwent permanent iodine-125-seed brachytherapy (median follow up 48 months). International Prostate Symptom Score and Radiation Therapy Oncology Group toxicity data were prospectively collected. Prostate volume, International Prostate Symptom Score before and after brachytherapy, and postimplant analysis were examined for an association with urinary toxicity, defined as Radiation Therapy Oncology Group urinary toxicity of Grade 1 or higher. Logistic regression analysis was used to examine the factors associated with urinary toxicity. The rate of Radiation Therapy Oncology Group urinary toxicity grade 1 or higher at 1, 6, 12, 24, 36 and 48 months was 67%, 40%, 21%, 31%, 27% and 28%, respectively. Grade 2 or higher urinary toxicity was less than 1% at each time-point. International Prostate Symptom Score was highest at 3 months and returned to normal 12 months after brachytherapy. On multivariate analysis, patients with a larger prostate size, greater baseline International Prostate Symptom Score, higher prostate V100, higher prostate V150, higher prostate D90 and a greater number of seeds had more acute urinary toxicities at 1 month and 12 months after brachytherapy. On multivariate analysis, significant predictors for urinary toxicity at 1 month and 12 months were a greater baseline International Prostate Symptom Score and prostate V100. Most urinary symptoms are tolerated and resolved within 12 months after prostate brachytherapy. Acute and late urinary toxicity after brachytherapy is strongly related to the baseline International Prostate Symptom Score and prostate V100. (author)

    Full Text Available 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.

    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). 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. 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. 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.

    The objective of this study was to evaluate acute morbidity, radiation dermatitis and pneumonitis, of Japanese patients treated with whole breast hypofractionated radiotherapy (RT) after breast-conserving surgery (BCS), compared to conventional RT. Japanese patients who received whole breast RT after BCS between October 2003 and September 2006 were retrospectively reviewed. Patients who had selected the conventional or hypofractionated schedule received whole breast irradiation of 50 Gy in 25 fractions plus boost or 40 Gy in 16 fractions plus boost. Radiation dermatitis and symptomatic pneumonitis were graded according to the Common Terminology Criteria for Adverse Events version 3.0. Of 443 consecutive patients, 377 (85%) received the conventional schedule and 66 (15%) received the hypofractionated schedule. Of patients treated with the conventional schedule, Grade 0, 1, 2 and 3 radiation dermatitis were observed in 16 (4%), 278 (74%), 77 (20%) and 6 (2%), respectively. Of patients treated with the hypofractionated schedule, Grade 0, 1, 2 and 3 dermatitis were observed in 11 (17%), 49 (74%), 5 (8%) and 1 (1%), respectively. Grade 2-3 dermatitis by the hypofractionated schedule (9%) was observed less frequently than that by the conventional schedule (22%) (chi-square test; P=0.016). Moreover, of patients treated with the conventional schedule, 4 (1%) had Grade 2 radiation pneumonitis. No patient treated with the hypofractionated schedule had symptomatic pneumonitis. Radiation dermatitis and pneumonitis in Japanese patients treated with the hypofractionated schedule is acceptable. Especially, radiation dermatitis by the hypofractionated schedule is milder than that by the conventional schedule. (author)

Analyzed subjects were 653 Japanese OSA patients (619 males and 34 females treated with CPAP at a sleep laboratory in a respiratory clinic in a Japanese city. Based on Bandura's social cognitive theory, the CPAP Self-Efficacy Questionnaire for Sleep Apnea in Japanese (CSESA-J was developed by a focus group of experts, using a group interview of OSA patients for the items of two previous self-efficacy scales for Western sleep apnea patients receiving CPAP treatment. CSESA-J has two subscales, one for self-efficacy and the other for outcome expectancy, and consists of a total of 15 items. Content validity was confirmed by the focus group. Confirmatory factor analysis showed that the factor loadings of self-efficacy and outcome expectancy were 0.47–0.76 and 0.41–0.92, respectively, for the corresponding items. CSESA-J had a significant but weak positive association with the General Self-Efficacy Scale, and a strong positive association with “Self-efficacy scale on health behavior in patients with chronic disease.” Cronbach’s alpha coefficient was 0.85 for the self-efficacy subscale and 0.89 for the outcome expectancy subscale.

    Full Text Available Abstract Background The Apo-1/Fas (CD95 molecule is an apoptosis-signaling cell surface receptor belonging to the tumor necrosis factor (TNF receptor family. Both Fas and Fas ligand (FasL are expressed in activated mature T cells, and prolonged cell activation induces susceptibility to Fas-mediated apoptosis. The Apo-1/Fas gene is located in a chromosomal region that shows linkage in multiple sclerosis (MS genome screens, and studies indicate that there is aberrant expression of the Apo-1/Fas molecule in MS. Methods Mva I polymorphism on the Apo-1/Fas promoter gene was detected by PCR-RFLP from the DNA of 114 Japanese patients with conventional MS and 121 healthy controls. We investigated the association of the Mva I polymorphism in Japanese MS patients using a case-control association study design. Results We found no evidence that the polymorphism contributes to susceptibility to MS. Furthermore, there was no association between Apo-1/Fas gene polymorphisms and clinical course (relapsing-remitting course or secondary-progressive course. No significant association was observed between Apo-1/Fas gene polymorphisms and the age at disease onset. Conclusions Overall, our findings suggest that Apo-1/Fas promoter gene polymorphisms are not conclusively related to susceptibility to MS or the clinical characteristics of Japanese patients with MS.

    Usher syndrome (USH) is an autosomal recessive disorder characterized by retinitis pigmentosa and hearing loss. USH type 1 (USH1), the second common type of USH, is frequently caused by MYO7A and CDH23 mutations, accounting for 70-80% of the cases among various ethnicities, including Caucasians, Africans and Asians. However, there have been no reports of mutation analysis for any responsible genes for USH1 in Japanese patients. This study describes the first mutation analysis of MYO7A and CDH23 in Japanese USH1 patients. Five mutations (three in MYO7A and two in CDH23) were identified in four of five unrelated patients. Of these mutations, two were novel. One of them, p.Tyr1942SerfsX23 in CDH23, was a large deletion causing the loss of 3 exons. This is the first large deletion to be found in CDH23. The incidence of the MYO7A and CDH23 mutations in the study population was 80%, which is consistent with previous findings. Therefore, mutation screening for these genes is expected to be a highly sensitive method for diagnosing USH1 among the Japanese.

    Thailand's policy to promote long-stay tourism encourages Japanese retirees to relocate to Thailand. One concern of such an influx is the impact of these elderly foreign residents on the Thai health system. This study aims to reveal the current use of and needs for health services amongst Japanese retirees residing in various locations in Thailand. In collaboration with nine Japanese self-help clubs in Bangkok, Chiang Mai, Chiang Rai, and Phuket, questionnaire surveys of Japanese long-stay retirees were conducted from January to March 2015. The inclusion criteria were being ≥ 50 years of age and staying in Thailand for ≥30 days in the previous 12 months while the main exclusion criteria included relocation by company, relocation due to marriage, or working migrants. The mean age of the 237 eligible participants was 68.8, with 79.3% of them being male, 57.8% having stayed in Thailand for ≥5 years, 63.3% having stayed in Thailand for ≥300 days in the previous 12 months and 33% suffering from chronic diseases or sequelae. Of the 143 who had health check-ups in the previous 12 months, 48.3% did so in Thailand. The top 3 diseases treated either in Thailand or Japan in the previous 12 months were dental diseases (50 patients), hypertension (44 patients), and musculoskeletal disorders (41 patients), with the rate of treatment in Thailand standing at 46.0, 47.7, and 65.9%, respectively. Of the 106 who saw a doctor in Thailand in the same period, 70.8% did so less than once a month. Only 23.2% of the participants preferred to receive medical treatment for serious conditions in Thailand. However, this number rose to 32.9% for long-term care (LTC) use. The usage of Thai health services amongst Japanese long-stay retirees is currently limited as they prefer going back to Japan for health screenings and treatment of chronic or serious diseases. However, the number of Japanese residents requiring health services including LTC and end-of-life care is expected

  19. Asymptomatic Esophageal Varices Should Be Endoscopically Treated

    Full Text Available Endoscopic treatment has generally been accepted in the management of bleeding esophageal varices. Both the control of acute variceal bleeding and elective variceal eradication to prevent recurrent bleeding can be achieved via endoscopic methods. In contrast to acute and elective treatment, the role of endoscopic therapy in asymptomatic patients who have never had variceal bleeding remains controversial because of the rather disappointing results obtained from prophylactic sclerotherapy. Most published randomized controlled trials showed that prophylactic sclerotherapy had no effect on survival. In some studies, neither survival rate nor bleeding risk was improved. In this article, the author champions the view that asymptomatic esophageal varices should be endoscopically treated.

    A protective effect of excessive body mass index (BMI) on mortality or functional outcome in patients with stroke is not well established in the Asian population. This study aimed to explore whether obese patients with stroke have advantages for functional improvement in Japanese rehabilitation wards. This retrospective cohort study included consecutive patients with stroke admitted and discharged from convalescent rehabilitation wards between 2011 and 2015. Demographic data, BMI, Functional Independence Measure (FIM) score, and nutritional status were analyzed. Participants were classified into 4 groups according to BMI (underweight stroke may have some advantages for functional recovery in rehabilitation wards. Copyright © 2015 National Stroke Association.

    We have obtained previous evidence of limbic dysfunction in middle-aged, asymptomatic offspring of late-onset Alzheimer's disease (LOAD) patients, and failure to recover from proactive semantic interference has been shown to be a sensitive cognitive test in other groups at risk for LOAD. To assess the effects of specific proactive semantic interference deficits as they relate to functional magnetic resonance imaging (fMRI) neocortical and limbic functional connectivity in middle aged offspring of individuals with LOAD (O-LOAD) and age-equivalent controls. We examined 21 O-LOAD and 20 controls without family history of neurodegenerative disorders (CS) on traditional measures of cognitive functioning and the LASSI-L, a novel semantic interference test uniquely sensitive to the failure to recover from proactive interference (frPSI). Cognitive tests then were correlated to fMRI connectivity of seeds located in entorhinal cortex and anterodorsal thalamic nuclei among O-LOAD and CS participants. Relative to CS, O-LOAD participants evidenced lower connectivity between entorhinal cortex and orbitofrontal, anterior cingulate, and anterior temporal cortex. In the offspring of LOAD patients, LASSI-L measures of frPSI were inversely associated with connectivity between anterodorsal thalamus and contralateral posterior cingulate. Intrusions on the task related to frPSI were inversely correlated with a widespread connectivity network involving hippocampal, insular, posterior cingulate, and dorsolateral prefrontal cortices, along with precunei and anterior thalamus in this group. Different patterns of connectivity associated with frPSI were observed among controls. The present results suggest that both semantic interference deficits and connectivity abnormalities might reflect limbic circuit dysfunction as a very early clinical signature of LOAD pathology, as previously demonstrated for other limbic phenotypes, such as sleep and circadian alterations.

    Inter-arm blood pressure (BP) difference has been associated with ischemic stroke. Local atherosclerosis of stroke differ among vulnerable individuals, whereas intracranial arterial stenosis (ICAS) is more frequently affected Asians, and extracranial arterial stenosis (ECAS) is more prevalent among whites. We hereby sought to explore the association of inter-arm BP difference with ICAS and ECAS in stroke-free hypertensive patients in Chinese population. All the 885 subjects were evaluated of ICAS and ECAS through computerized tomographic angiography. Both arm BP was measured simultaneously by Vascular Profiler-1000 device. In the continuous study, ICAS was significantly associated with age, male, average brachial SBP, diabetes, anti-hypertensive treatment and inter-arm DBP difference. ECAS was associated with age, inter-arm SBP and LDL. In the categorical study, subjects with the top quartile of inter-arm DBP difference (≥4 mmHg) showed significantly higher risk of ICAS (OR = 2.109; 95% CI, 1.24-3.587). And the participants with the top quartile of inter-arm SBP difference (≥6 mmHg) showed significantly higher risk of ECAS (OR = 2.288; 95% CI, 1.309-3.998). In conclusion, we reported a diverse association of inter-arm SBP/DBP difference with the ICAS/ECAS. Inter-arm DBP difference might be the early symbol of ICAS in Chinese population, which need further verification in long-term cohort study.

  5. Ultrasonography in the diagnosis of asymptomatic hyperuricemia and gout.

    Puig, J G; Beltrán, L M; Mejía-Chew, C; Tevar, D; Torres, R J

    2016-12-01

    Sonography has detected urate deposits in 34%-42% of the patients with asymptomatic hyperuricemia. This may prompt reclassification of asymptomatic hyperuricemia into "asymptomatic gout" and consideration of urate lowering therapy (ULT) to resolve urate deposits. In patients with gout and no visible tophi, sonography has detected urate deposits in half of the patients. This may allow diagnosing "tophaceous gout" and influencing the serum urate target level, prophylaxis to avoid acute gout flares during ULT, and clinical follow-up. Current accessibility to sonography may better classify patients with hyperuricemia and gout and contribute to delineate therapeutic objectives and clinical guidance.

    A nationwide survey was conducted to clarify the epidemiological features of patients with chronic pancreatitis (CP) in Japan. In the first survey, both the prevalence and the incidence of CP in 2011 were estimated. In the second survey, the clinicoepidemiological features of the patients were clarified by mailed questionnaires. Patients were diagnosed by the Japanese diagnostic criteria for chronic pancreatitis 2009. The estimated annual prevalence and incidence of CP in 2011 were 52.4/100,000 and 14.0/100,000, respectively. The sex ratio (male/female) of patients was 4.6, with a mean age of 62.3 years. Alcoholic (67.5%) was the most common and idiopathic (20.0%) was the second most common cause of CP. Comorbidity with diabetes mellitus (DM) and pancreatic calcifications (PC) occurred more frequent in ever smokers independently of their drinking status. Among patients without drinking habit, the incidences of DM and PC were significantly higher in ever smokers than in never smokers. The multiple logistic regression analysis revealed smoking was an independent factor of DM and PC in CP patients: DM, Odds ratio (OR) 1.644, 95% confidence interval (CI) 1.202 to 2.247 (P = 0.002): PC, OR 2.010, 95% CI 1.458 to 2.773 (P smoking was not identified as an independent factor for the appearance of abdominal pain by this analysis. The prevalence of Japanese patients with CP has been increasing. Smoking was identified as an independent factor related to DM and PC in Japanese CP patients. Copyright © 2014 IAP and EPC.

    Hepatitis C virus (HCV) subtype 1b, which infects approximately 70% of Japanese carriers, is likely to be more eradicable by a telaprevir regimen than subtype 1a because of the higher genetic barrier of Val36 and Arg155 substitutions. The aims of this exploratory study were to evaluate the virological response and safety of 24-week oral administration of telaprevir alone in chronic HCV subtype 1b infection. Fifteen treatment-naïve patients were treated with telaprevir 750 mg every 8 h for 24 weeks. All patients were Japanese whose median age was 58.0 years (range: 45–68), and six patients (40%) were men. Median baseline HCV RNA level was 6.80 log10 IU/mL (range: 3.55–7.10). The HCV RNA levels decreased to undetectable in five patients (33%) within 8 weeks. Three patients (20%) with negative HCV RNA by Week 4 achieved end of treatment response. One patient (7%) who achieved sustained virological response had a low baseline viraemia of 3.55 log10 IU/mL. Most of the adverse events including anaemia and skin disorders were mild to moderate. Developed variants were T54A and A156V/T/F/Y with or without secondary substitutions rather than V36M ± R155K. Telaprevir alone for 24 weeks in Japanese patients with HCV subtype 1b resulted in an sustained viral response rate of 7% (1/15) and was well tolerated for 24 weeks. These results will support the implementation of further studies on oral combination of telaprevir with other direct-acting antiviral agents in patients infected with HCV subtype 1b. PMID:23383655

    Inflammatory bowel disease (IBD) has an unknown etiology; however, accumulating evidence suggests that IBD is a multifactorial disease influenced by a combination of genetic and environmental factors. The influence of genetic variants on DNA methylation in cis and cis effects on expression have been demonstrated. We hypothesized that IBD susceptibility single-nucleotide polymorphisms (SNPs) regulate susceptibility gene expressions in cis by regulating DNA methylation around SNPs. For this, we determined cis-regulated allele-specific DNA methylation (ASM) around IBD susceptibility genes in CD4+ effector/memory T cells (Tem) in lamina propria mononuclear cells (LPMCs) in patients with IBD and examined the association between the ASM SNP genotype and neighboring susceptibility gene expressions. CD4+ effector/memory T cells (Tem) were isolated from LPMCs in 15 Japanese IBD patients (ten Crohn's disease [CD] and five ulcerative colitis [UC] patients). ASM analysis was performed by methylation-sensitive SNP array analysis. We defined ASM as a changing average relative allele score ([Formula: see text]) >0.1 after digestion by methylation-sensitive restriction enzymes. Among SNPs showing [Formula: see text] >0.1, we extracted the probes located on tag-SNPs of 200 IBD susceptibility loci and around IBD susceptibility genes as candidate ASM SNPs. To validate ASM, bisulfite-pyrosequencing was performed. Transcriptome analysis was examined in 11 IBD patients (seven CD and four UC patients). The relation between rs36221701 genotype and neighboring gene expressions were analyzed. We extracted six candidate ASM SNPs around IBD susceptibility genes. The top of [Formula: see text] (0.23) was rs1130368 located on HLA-DQB1. ASM around rs36221701 ([Formula: see text] = 0.14) located near SMAD3 was validated using bisulfite pyrosequencing. The SMAD3 expression was significantly associated with the rs36221701 genotype (p = 0.016). We confirmed the existence of cis-regulated ASM around

  11. Identification and characterization of HIV-2 strains obtained from asymptomatic patients that do not use CCR5 or CXCR4 coreceptors

    2003-01-01

    In vivo, human immunodeficiency virus type 2 (HIV-2) infection reveals several unique characteristics when compared to HIV-1 infection, the most remarkable of which is the extraordinarily long asymptomatic period. Here we describe two HIV-2 primary isolates, obtained from asymptomatic individuals, which do not infect any coreceptor-expressing cell lines tested. In those cells, we show that the absence of replication is directly related to cell entry events. Furthermore, productive infection observed in peripheral blood mononuclear cells (PBMC) was not inhibited by natural ligands and monoclonal antibodies directed to CCR5 and CXCR4. Finally, viral entry efficiency and viral progeny production of these viruses are markedly impaired in PBMC, indicating a reduced replicative fitness of both viruses. In conclusion, our data suggest that in some HIV-2 asymptomatic individuals, the circulating viruses are unable to use the major coreceptors to infect PBMC. This fact should have important implications in HIV-2 pathogenesis and transmission

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

    We investigated the disease progression and survival in 230 Japanese patients with multiple system atrophy (MSA; 131 men, 99 women; 208 probable MSA, 22 definite; mean age at onset, 55.4 years). Cerebellar dysfunction (multiple system atrophy-cerebellar; MSA-C) predominated in 155 patients, and parkinsonism (multiple system atrophy-parkinsonian; MSA-P) in 75. The median time from initial symptom to combined motor and autonomic dysfunction was 2 years (range 1-10). Median intervals from onset to aid-requiring walking, confinement to a wheelchair, a bedridden state and death were 3, 5, 8 and 9 years, respectively. Patients manifesting combined motor and autonomic involvement within 3 years of onset had a significantly increased risk of not only developing advanced disease stage but also shorter survival (P bedridden state, P bedridden state (P = 0.03) and death (P bedridden state and survival were no worse. Gender was not associated with differences in worsening of function or survival. On MRI, a hyperintense rim at the lateral edge of the dorsolateral putamen was seen in 34.5% of cases, and a 'hot cross bun' sign in the pontine basis (PB) in 63.3%. These putaminal and pontine abnormalities became more prominent as MSA-P and MSA-C features advanced. The atrophy of the cerebellar vermis and PB showed a significant correlation particularly with the interval following the appearance of cerebellar symptoms in MSA-C (r = 0.71, P r = 0.76 and P < 0.01, respectively), but the relationship between atrophy and functional status was highly variable among the individuals, suggesting that other factors influenced the functional deterioration. Atrophy of the corpus callosum was seen in a subpopulation of MSA, suggesting hemispheric involvement in a subgroup of MSA patients. The present study suggested that many factors are involved in the progression of MSA but, most importantly, the interval from initial symptom to combined motor and autonomic dysfunction can predict functional

    Home telemonitoring is becoming more important to home medical care for patients with heart failure. Since there are no data on home telemonitoring for Japanese patients with heart failure, we investigated its effect on cardiovascular outcomes. The HOMES-HF study was the first multicenter, open-label, randomized, controlled trial (RCT) to elucidate the effectiveness of home telemonitoring of physiological data, such as body weight, blood pressure, and pulse rate, for Japanese patients with heart failure (UMIN Clinical Trials Registry 000006839). The primary end-point was a composite of all-cause death or rehospitalization due to worsening heart failure. We analyzed 181 recently hospitalized patients with heart failure who were randomly assigned to a telemonitoring group (n = 90) or a usual care group (n = 91). The mean follow-up period was 15 (range 0-31) months. There was no statistically significant difference in the primary end-point between groups [hazard ratio (HR), 0.95; 95% confidence interval (CI), 0.548-1.648; p = 0.572]. Home telemonitoring for Japanese patients with heart failure was feasible; however, beneficial effects in addition to those of usual care were not demonstrated. Further investigation of more patients with severe heart failure, participation of home medical care providers, and use of a more integrated home telemonitoring system emphasizing communication as well as monitoring of symptoms and physiological data are required.

    Serum antibody against carbonic anhydrase (CA) II has been described as a serological marker for distinguishing autoimmune cholangitis (AIC) from primary biliary cirrhosis (PBC). To validate this finding in a Japanese population, we evaluated sera from patients with PBC and AIC for antibody to human CA II. An enzyme-linked immunosorbent assay was employed to quantify serum antibody against CA II in patients with PBC (n = 40), AIC (n = 23), autoimmune hepatitis (n = 10), and extrahepatic obstructive jaundice (n = 10). Compared with the finding of a 4% prevalence of anti-CAII antibody in healthy subjects (n = 24), a significantly higher prevalence of anti-CA II antibody was detected in patients with PBC (35%) and AIC (30%) (P jaundice. No significant difference was observed between PBC and AIC patients. These results showed that AIC and PBC would be indistinguishable by anti-CA II antibody testing in Japanese patients. However, the finding of serum anti-CA II antibody in patients with PBC and AIC supports the disease concept of autoimmune exocrinopathy.

    A post-marketing surveillance (PMS) program was implemented to assess the safety and effectiveness of tacrolimus (TAC) in Japanese rheumatoid arthritis (RA) patients and to identify risk factors related to adverse drug reactions (ADRs). Patients were registered centrally and monitored for all adverse events (AEs) for 24 weeks. Effectiveness was evaluated using the Disease Activity Score 28-CRP (DAS28-CRP). Data from 3,172 patients (mean age 62.2 years) were evaluated in the safety analysis. Of the safety population, 78.5 %were female and 25.9 % were in Steinbrocker's functional class 3 or 4. TAC was prescribed as monotherapy in 52.5 % and the most common concomitant disease modifying antirheumatic drug (DMARD) was methotrexate, used in 28.9 % of the patients. The incidence of AEs, serious AEs (SAEs), ADRs and serious ADRs were 41.2, 6.4, 36.0, and 4.9 %, respectively. The most frequent serious ADR category was infections and infestations. Age ≥ 65 years, concurrent renal dysfunction, and concurrent diabetes mellitus were identified as significant risk factors for ADR. Based on EULAR response criteria, 65.4 % of the patients showed moderate or good response. The results demonstrate that TAC is well tolerated by Japanese patients with active RA, including those receiving concomitant methotrexate, in the real world.

  17. Vaccination and Infection as Causative Factors in Japanese Patients With Rasmussen Syndrome: Molecular Mimicry and HLA Class I

    2006-01-01

    Full Text Available Rasmussen syndrome is an intractable epilepsy with a putative causal relation with cellular and humoral autoimmunity. Almost half of the patients have some preceding causative factors, with infections found in 38.2%, vaccinations in 5.9% and head trauma in 8.9% of Japanese patients. In a patient with seizure onset after influenza A infections, cross-reaction of the patient's lymphocytes with GluRε2 and influenza vaccine components was demonstrated by lymphocyte stimulation test. Database analyses revealed that influenza A virus hemagglutinin and GluRε2 molecules contain peptides with the patient's HLA class I binding motif (HLA ࢤ A*0201. The relative risks of HLA class I genotypes for Rasmussen syndrome are 6.1 (A*2402, 6.4 (A*0201, 6.3 (A*2601 and 11.4 (B*4601. The relative risks of HLA class I-A and B haplotypes are infinity (A*2601+B*5401, 21.1 (A*2402+B*1501, 13.3 (A*2402+B*4801 and 5.1 (A*2402+B*5201. Some alleles and haplotypes of HLA class I may be the risk factors in Japanese patients. Cross-reactivity of cytotoxic T lymphocytes may contribute to the processes leading from infection to the involvement of CNS.

    This study was undertaken to evaluate safety and pharmacokinetics and to determine treatment doses of vorinostat plus bortezomib in Japanese patients with relapsed or refractory multiple myeloma (MM). Of 9 originally enrolled patients, 2 were refractory to bortezomib, and both experienced dose-limiting toxicity (DLT), prompting a protocol amendment to exclude bortezomib-refractory individuals. Patients not considered bortezomib refractory (N = 7) received 21-day cycles of 1.3 mg/m(2) intravenous bortezomib (Days 1, 4, 8, and 11) and oral vorinostat 400 mg (Days 1 through 14) and were further evaluated. Vorinostat and bortezomib treatment doses were determined by DLT and safety, tolerability, and treatment response were assessed. Of 7 enrolled patients, 6 were evaluated, and one developed DLTs. The most common adverse events were leukopenia, neutropenia, thrombocytopenia, diarrhea, nausea, decreased appetite, and vomiting. Combination of vorinostat plus bortezomib did not increase vorinostat exposure at Day 11 [AUC0-24 h ratio (95% CI) = 1.08 (0.80, 1.45)]; geometric mean AUC0-24 h ratio for bortezomib (90% CI) was 1.96 (1.24-3.12). Objective therapeutic response occurred in 3 patients, including 1 complete response and 2 partial responses. Vorinostat 400 mg plus bortezomib 1.3 mg/m(2) was safe and well-tolerated in Japanese patients with relapsed or refractory MM not considered bortezomib refractory (NCT00858234).

    Ruxolitinib, a potent JAK1/JAK2 inhibitor, was found to be superior to the best available therapy (BAT) in controlling hematocrit, reducing splenomegaly, and improving symptoms in the phase 3 RESPONSE study of patients with polycythemia vera with splenomegaly who experienced an inadequate response to or adverse effects from hydroxyurea. We report findings from a subgroup analysis of Japanese patients in RESPONSE (n = 18). The composite response rate (hematocrit control and spleen response) was higher in patients receiving ruxolitinib (50.0%) than in those receiving BAT (8.3%). A total of 50.0% of patients randomized to ruxolitinib achieved a spleen response vs 8.3% of those receiving BAT; 100 and 33.3% of patients in the respective groups achieved hematocrit control, with mean hematocrit in ruxolitinib-treated patients remaining stable at hydroxyurea.

    High fluctuations in blood glucose are associated with various complications. The correlation between glycated hemoglobin (HbA1c) level and fluctuations in blood glucose level has not been studied in Japanese patients with type 2 diabetes. In the present study, blood glucose profile stratified by HbA1c level was evaluated by continuous glucose monitoring (CGM) in Japanese type 2 diabetes patients. Our retrospective study included 294 patients with type 2 diabetes who were divided by HbA1c level into five groups (≥6.0 to level and CGM data was analyzed. The primary end-point was the difference in blood glucose fluctuations among the HbA1c groups. The mean blood glucose level increased significantly with increasing HbA1c (P trend  levels of maximum blood glucose, minimum blood glucose, each preprandial blood glucose, each postprandial maximum blood glucose, range of increase in postprandial glucose from pre-meal to after breakfast, the area under the blood concentration-time curve >180 mg/dL and percentage of the area under the blood concentration-time curve >180 mg/dL were higher with higher HbA1c. Mean glucose level and pre-breakfast blood glucose level were significant and independent determinants of HbA1c. In Japanese patients treated for type 2 diabetes, the mean amplitude of glycemic excursions did not correlate with HbA1c, making it difficult to assess blood glucose fluctuations using HbA1c. Parameters other than HbA1c are required to evaluate fluctuations in blood glucose level in patients receiving treatment for type 2 diabetes. © 2017 The Authors.

    Massage therapy is one of the most commonly used complementary therapies for patients with Parkinson's disease (PD). The aim of this preliminary study was to evaluate the effects of traditional Japanese massage therapy on various symptoms of patients with PD. The study design was a case series study. The study was conducted at the Center for Integrative Medicine, Tsukuba University of Technology, Japan. The subjects were 10 patients with idiopathic PD (mean age, 69.6±7.7 years; range, 55-85 years) who presented for consultation with a neurologist between February and April 2009 and who desired massage therapy in conjunction with standard pharmaceutical treatment. The intervention comprised a 30-minute session of traditional Japanese massage in conjunction with standard conventional medication. The outcome measures were as follows: Gait speed in the 20-m walk test (10-m walk and return) for gait disturbance, angular range of shoulder joint motion for frozen shoulder, and a visual analogue scale (VAS) for assessing the severity of each of various symptoms (hypophonia, shoulder stiffness, muscle pain, heaviness or lassitude of a body part, and fatigue), as determined before and after the massage session. (1) Patients with gait disturbance showed improved gait speed, (2) those with frozen shoulder showed improved range of motion of the shoulder joint, and (3) VAS scores for assessing the severity of other subjective symptoms were improved. These results suggest that traditional Japanese massage therapy used in combination with medication is effective for alleviating various symptoms in patients with PD and may contribute to enhancing their health-related quality of life. Larger studies with a control group are required to verify these findings.

    Retinitis pigmentosa (RP), a major cause of blindness in developed countries, has multiple causative genes; its prevalence differs by ethnicity. Usher syndrome is the most common form of syndromic RP and is accompanied by hearing impairment. Although molecular diagnosis is challenging, recent technological advances such as targeted high-throughput resequencing are efficient screening tools. We performed comprehensive molecular testing in 329 Japanese RP and Usher syndrome patients by using a custom capture panel that covered the coding exons and exon/intron boundaries of all 193 known inherited eye disease genes combined with Illumina HiSequation 2500. Candidate variants were screened using systematic data analyses, and their potential pathogenicity was assessed according to the frequency of the variants in normal populations, in silico prediction tools, and compatibility with known phenotypes or inheritance patterns. Molecular diagnoses were made in 115/317 RP patients (36.3%) and 6/12 Usher syndrome patients (50%). We identified 104 distinct mutations, including 66 novel mutations. EYS, USH2A, and RHO were common causative genes. In particular, mutations in EYS accounted for 15.0% of the autosomal recessive/simplex RP patients or 10.7% of the entire RP cohort. Among the 189 previously reported mutations detected in the current study, 55 (29.1%) were found commonly in Japanese or other public databases and were excluded from molecular diagnoses. By screening a large cohort of patients, this study catalogued the genetic variations involved in RP and Usher syndrome in a Japanese population and highlighted the different distribution of causative genes among populations.

    To find the real incidence and risk factors in asymptomatic cerebral infarction, a retrospective review was made on magnetic resonance (MR) images, which were obtained from 713 outpatients seen at the Geriatrics Research Institute Hospital between March and November of 1990. The criteria for asymptomatic cerebral infarction are: high signal intensity areas larger than 3 mm in diameter on T2-weighted image; no history of stroke; no neurological and psychological signs or symptoms with or without subjective symptoms. Symptomatic cerebral stroke was defined as stroke episodes associated with neurological signs and infarction lesions on CT or MR imaging. Of a total of 713 patients, 215 (30.2%) had symtomatic cerebral infarction and 384 (53.9%) had no cerebral lesions. The incidence of asymptomatic cerebral infarction increased with aging. Cerebral risk factors, i.e. hypertension, atrial fibrillation, and diabetes mellitus, were more significantly common in both symptomatic and asymptomatic groups than the normal control group. In the group of asymptomatic patients, T2-weighted images showed hyperintensity in the corona radiata in 60.9%, in the frontal lobe in 32.1%, in the semioval center in 28.8%, and in the basal ganglia in 23.7%. Periventricular hyperintensity was present in 124 of all 713 patients (17.4%). Common complaints in asymptomatic patients were headache (40.0%), dizziness (14.4%), and neck muscle contraction (9.8%). In conclusion, MR imaging may contribute to manage asymptomatic patients. (N.K.).

    Psychological factors have been suspected to be associated with the development of systemic lupus erythematosus (SLE) and patient's health status. However, psychological profiles among Japanese patients with SLE have been poorly understood. We started a prospective study of female patients with SLE in 1995. Using the baseline data from 279 patients in this prospective study, we cross-sectionally analyzed the relations of clinical factors and social factors to psychological factors, and the association between psychological factors and mental and physical health status. We used the Japanese notion ikigai as an indicator of mental health, and ambulatory activity as an indicator of their physical health, respectively. To measure psychological factors, the short-form of the Eysenck Personality Questionnaire-Revised (short EPQ-R) and the Multidimensional Health Locus of Control (HLOC) scale were used. Active phase of the disease was significantly related to the neuroticism score in the short EPQ-R. Educational level was inversely related to the scores of powerful others and chance HLOC belief. As for health status, the internal HLOC belief was significantly associated with ikigai, and the chance HLOC belief was inversely associated with ambulatory activity. The scores on the short EPQ-R (Extraversion/Introversion and Neuroticism) were exclusively related to ikigai. This study suggests that psychological factors may have effects on both the development of SLE and patient's health status.

    Evidence of characteristics of Japanese patients with diabetes from a large-scale population is necessary. Few studies have compared glycaemic controls, complications and comorbidities between type 1 and 2 diabetic patients. This paper focuses on illustrating a clinical picture of Japanese diabetic patients and comparing glycaemic control and prognoses between type 1 and 2 diabetes using multi-institutional data. The BioBank Japan Project enrolled adult type 1 and 2 diabetic patients between fiscal years 2003 and 2007. We have presented characteristics, controls of serum glucose, cholesterol and blood pressure, prevalence of complications and comorbidities and survival curves. We have also shown glycaemic controls according to various individual profiles of diabetic patients. A total of 558 type 1 diabetic patients and 30,834 type 2 diabetic patients participated in this study. The mean glycated haemoglobin A1c was higher in type 1 diabetes than in type 2 diabetes. In the type 1 diabetic patients, the glycated haemoglobin A1c had no consistent trend according to age and body mass index. The Kaplan-Meier estimates represented a longer survival time from baseline with type 1 diabetes than with type 2 diabetes. Compared with type 1 diabetic patients, type 2 diabetic patients had double the prevalence of macrovascular complications. This work has revealed detailed plasma glucose levels of type 1 and 2 diabetic patients according to age, body mass index, blood pressure, serum cholesterol levels and smoking and drinking habits. Our data have also shown that the prognosis is worse for type 2 diabetes than for type 1 diabetes in Japan. Copyright © 2017 The Authors. Production and hosting by Elsevier B.V. All rights reserved.

  7. Asymptomatic bacteriuria. Clinical significance and management.

    Raz, Raul

    2003-10-01

    The clinical significance and management of asymptomatic bacteriuria (ASB) differs according to different groups of patients. ASB requires antibiotic treatment in pregnant women, children aged 5-6 years and prior to invasive genitourinary procedures. However, there is a consensus that ASB in the elderly, healthy school girls and young women, diabetic women and patients with indwelling catheters or intermittent catheterization has no clinical significance and antibiotic prescription is not indicated.

    The clinicopathological profiles of 419 patients with asymptomatic gastric cancer (AGC) first detected by gastric screening, were reviewed and compared with those of the 1727 patients with symptomatic gastric cancer (SGC). The incidence of AGC increased gradually and has amounted to 30% of the total resected cases in recent years. About 75% of AGC cases were of early cancer and 84% were negative for lymph node metastases. In contrast, only 33% of SGC cases were of early cancer and 57% were no...

    Chronic kidney disease (CKD) eventually progresses to end-stage renal disease (ESRD). However, risk factors associated with CKD progression have not been well characterized in Japanese patients with CKD who are less affected with coronary disease than Westerners. A large-scale, multicenter, prospective, cohort study was conducted in patients with CKD and under nephrology care, who met the eligibility criteria [Japanese; age 20-75 years; and estimated glomerular filtration rate (eGFR): 10-59 mL/min/1.73 m 2 ]. The primary endpoint was a composite of time to a 50 % decline in eGFR from baseline or time to the initiation of renal replacement therapy (RRT). The secondary endpoints were the rate of decline in eGFR from baseline, time to a 50 % decline in eGFR from baseline, time to the initiation of RRT, and time to doubling of serum creatinine (Cre) concentration. 2966 patients (female, 38.9 %; age, 60. 3 ± 11.6 years) were enrolled. The incidence of the primary endpoint increased significantly (P < 0.0001) in concert with CKD stage at baseline. The multivariate Cox proportional hazards models revealed that elevated systolic blood pressure (SBP) [hazard ratio (HR) 1.203, 95 % confidence interval (CI) 1.099-1.318)] and increased albumin-to-creatinine ratio (UACR ≥ 1000 mg/g Cre; HR: 4.523; 95 % CI 3.098-6.604) at baseline were significantly associated (P < 0.0001, respectively) with the primary endpoint. Elevated SBP and increased UACR were risk factors that were significantly associated with CKD progression to ESRD in Japanese patients under nephrology care.

    To investigate the molecular and clinical characteristics of the largest series of Japanese patients with glucokinase maturity-onset diabetes of the young (GCK-MODY), and to find any features specific to Asian people. We enrolled 78 Japanese patients with GCK-MODY from 41 families (55 probands diagnosed at the age of 0-14 years and their 23 adult family members). Mutations were identified by direct sequencing or multiplex ligation-dependent probe amplification of all exons of the GCK gene. Detailed clinical and laboratory data were collected on the probands using questionnaires, which were sent to the treating physicians. Data on current clinical status and HbA1c levels were also collected from adult patients. A total of 35 different mutations were identified, of which seven were novel. Fasting blood glucose and HbA1c levels of the probands were ≤9.3 mmol/l and ≤56 mmol/mol (7.3%), respectively, and there was considerable variation in their BMI percentiles (0.4-96.2). In total, 25% of the probands had elevated homeostatic assessment of insulin resistance values, and 58.3% of these had evidence of concomitant Type 2 diabetes in their family. The HbA1c levels for adults were slightly higher, up to 61 mmol/mol (7.8%). The incidence of microvascular complications was low. Out of these 78 people with GCK-MODY and 40 additional family members with hyperglycaemia whose genetic status was unknown, only one had diabetic nephropathy. The molecular and clinical features of GCK-MODY in Japanese people are similar to those of other ethnic populations; however, making a diagnosis of GCK-MODY was more challenging in patients with signs of insulin resistance. © 2014 The Authors.

    Obtaining an adequate number of patients to conduct a natural history study for rare diseases such as Becker muscular dystrophy (BMD) is difficult. The present study used data from Remudy, a national registry for neuromuscular diseases in Japan, to conduct a phenotypic analysis of BMD. We analyzed Remudy data of participants with dystrophinopathy. All participants who were aged 17 and older and were ambulant at age 13 were included in this study. Participants were divided into two groups: those with BMD who were ambulant at age 17, and those with intermediate muscular dystrophy (IMD) who lost ambulation by age 17. Frequent mutations were analyzed by age at ambulation, cardiopulmonary function, and genotype. For clinical comparisons, participants who were administered steroids were excluded. From July 2009 through September 2015, 192 participants had registered with Remudy. Mean participant age was 34.80±13.3 (range, 17-78) years, and 52.1% of participants were ambulant. Of the entire study population, 50.5% had cardiomyopathy and 35.9% had respiratory failure. Three participants required invasive ventilation and 30 required non-invasive ventilation. Nineteen of the 30 non-invasive ventilator users were part-time users. In total, 138 (71.9%) had BMD and 54 (28.1%) had IMD. The most frequent mutation was ex45_ex47del (36 participants). Among participants with frequent in-frame mutations, those with the ex45-49del mutation lost their ambulation earlier than those with the ex45_ex47del mutation. A total of 67 different exon deletions and duplications were identified in the study population. We clarified the clinical phenotypes of Japanese patients with BMD/IMD using data from Remudy. Our results suggest that not only IMD but also BMD are associated with risk of respiratory dysfunction.

  12. Japanese language and Japanese science

    Tanikawa, Kiyotaka

    2003-08-01

    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.

    Full Text Available This cross-sectional study is conducted to determine the prevalence of asymptomatic cervical spine subluxation in rheumatoid arthritis patients by plain radiographs and its relation to demographic and clinical characteristics, disease activity measures and medications. 100 rheumatoid arthritis patients (18 male and 82 female were selected randomly, according to the American college of Rheumatology Criteria, who were under follow up in the rheumatology clinic. A complete history was taken, and physical examination has been done with focus on the cervical spine to determine their demographic data, disease duration, age of disease onset, drug history, swollen and tender joint counts, and ESR, Hb, CRP, RF levels. The disease activity of patients with rheumatoid arthritis was measured using the disease activity score 28. Radiographs of the cervical spine included lateral views taken in flexion, extension, neutral position of the neck and anterioposterior and odontoid projection view. Asymptomatic cervical spine subluxation was found in 17 of the 100 patients (17%. The prevalence of, anterior atlantoaxial subluxation, atlantoaxial impaction and subaxial subluxation was 10(10%, 5(5% and 6(6%, respectively. Posterior subluxation was not detected. The only characteristic that showed meaningful relationship with cervical spine subluxation was CRP (P=0.036. Our results showed that patients with RA, who have cervical spine subluxation cannot be distinguished on the basis of symptoms. Cervical spine involvement is common and may be asymptomatic, indicating routine cervical spine imaging is needed in patients with RA.

    We aimed to validate the reliability of the Medical Outcomes Study Short Form-36 (SF-36) among Japanese patients with systemic lupus erythematosus (SLE). Japanese patients with SLE ( n = 233) completed the SF-36 and other related demographic questionnaires, and physicians simultaneously completed the SLE Disease Activity Index 2000 (SLEDAI-2K) and the Systemic Lupus International Collaborating Clinics Damage Index (SDI). Patients were prospectively followed for a repeat assessment the following year. The SF-36 subscales demonstrated acceptable internal consistency (Cronbach's α of 0.85-0.89), and an overall good test-retest reliability (intraclass correlation coefficient >0.70). The average baseline SF-36 subscale/summary scores except for "bodily pain" were significantly lower than those of the Japanese general population ( p 36 subscale/summary scores except for "vitality" and "mental component summary" at baseline, whereas the SLEDAI-2K did not. In the second year, "social functioning" and "mental component summary" of the SF-36 deteriorated among patients whose SDI or SLEDAI-2K score increased (effect sizes 36 demonstrated acceptable reliability among Japanese patients with SLE. Health-related quality of life measured by the SF-36 was reduced in Japanese patients with SLE and associated with disease damage, rather than disease activity.

  15. A Retrospective Study of G-Tube Use in Japanese Patients Treated with Concurrent Chemoradiotherapy for Hypopharyngeal Cancer.

    Akihiro Homma

    Full Text Available Late toxicity after concurrent chemoradiotherapy (CCRT, such as dysphagia, in patients with squamous cell carcinoma of the head and neck has received a good deal of attention recently. The gastrostomy tube (G-tube dependence rate 1 year after CCRT was reported to be 16.7-42.9% in Western countries. We evaluated swallowing outcomes after CCRT in patients with hypopharyngeal cancer (HPC treated in our hospital and compared them with previous reports.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.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.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.

  16. No correlation between PNPLA3 rs738409 genotype and fatty liver and hepatic cirrhosis in Japanese patients with HCV.

    Masato Nakamura

    Full Text Available BACKGROUND: Hepatitis C virus (HCV infection is associated with the development of cirrhosis and hepatocellular carcinoma and is also related to fatty change of the liver. Variation in patatin-like phospholipase domain-containing 3 (PNPLA3 gene is associated with disease progression in nonalcoholic fatty liver disease (NAFLD. Recent reports have suggested that PNPLA3, IL28B and TLR4-associated single nucleotide polymorphisms (SNPs may have an impact on hepatic steatosis or fibrosis in patients with chronic HCV infection. METHODS AND FINDINGS: Four SNPs (PNPLA3 rs738409, TLR4 rs4986790, TLR4 rs4986791, IL28B rs8099917 were identified in Japanese patients infected with HCV. We examined the association between the distribution of these SNP alleles and fatty change of the liver or existence of hepatic cirrhosis diagnosed by ultrasonography, one of the widely accessible and easy-to-use methods. PNPLA3 rs738409 G-allele and IL28B rs 8099917 minor allele were found in 70.0% and 31.1%, respectively. These two TLR4 SNPs were uniform in Japanese. Fatty change of the liver developed independent of the abscence of hepatic cirrhosis on sonographic findings and younger age. Hepatic cirrhosis was associated with a higher aspartate aminotransferase/platelet ratio index (APRI, no fatty change of the liver, higher BMI and higher AFP levels. No association between PNPLA3 rs738409/IL28B rs8099917 genotypes and hepatic steatosis or liver fibrosis was observed. CONCLUSIONS: According to ultrasound examinations, no association between PNPLA3 rs738409 genotype and fatty change of the liver or hepatic cirrhosis was found in Japanese patients infected with HCV. Together, our results suggested that the mechanism of hepatic steatosis underlying HCV infection might differ from that of NAFLD and should be explored.

    Background/Aim The definition of muscle atrophy (pre-sarcopenia) and its diagnostic criteria have not been well reported. To elucidate the frequency of pre-sarcopenia in chronic liver disease (CLD), we examined clinical features of Japanese CLD patients using abdominal computed tomography (CT) findings. Methods We enrolled 988 CLD (736 with na?ve hepatocellular carcinoma) and 372 normal control subjects (NCs). The psoas muscle area index [PI, psoas muscle area at the mid-L3 level in CT (cm2)/...

    Mandibular hypoplasia, deafness, progeroid features and lipodystrophy (MDPL) syndrome is a rare autosomal dominant disorder caused by heterozygous POLD1 mutations. To date, 13 patients affected by POLD1 mutation-caused MDPL have been described. We report a clinically undiagnosed 11-year-old male who noted joint contractures at 6 years of age. Targeted exome sequencing identified a known POLD1 mutation [NM_002691.3:c.1812_1814del, p.(Ser605del)] that diagnosed him as the first Japanese/East Asian MDPL case.

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

    Before this work a Japanese version of the Toronto Extremity Salvage Score (TESS), a disease-specific patient-completed questionnaire widely used to assess the physical function of patients with musculoskeletal tumors, had not been developed. The purpose of this study was cross-cultural adaptation and validation of the English-language version of the TESS to facilitate international comparisons of treatment results. The TESS was translated into Japanese, back-translated into English, and reviewed by a committee to develop a consensus Japanese version of the TESS. One hundred and two patients were assessed by use of this Japanese version to examine its reliability and validity. Test-retest reliability and internal consistency determined by using the intraclass correlation coefficient (0.941) and Cronbach's alpha test (0.978), respectively, were excellent. Factor analysis showed that the structure consisted of a three-item cluster; the Akaike information criterion (AIC) network also demonstrated that the items could be divided into three domains in accordance with their content. The Japanese version of the TESS correlated with the Musculoskeletal Tumor Society rating scale (r = 0.811; P TESS is a reliable and valid instrument for measuring patient-reported functional outcome for patients with lower extremity sarcoma, and that it enables international comparisons of treatment results. The spatial association of each item demonstrated by using the AIC network also suggested that the underlying structure of the TESS reflected its coverage of a wide range of physical functions.

    The aim of this study was to explore the most suitable religious care for Japanese terminally ill patients with cancer based on the opinions of bereaved family members. A multicenter questionnaire survey on palliative care service was sent to 592 bereaved family members of patients with cancer who were admitted to palliative care units in Japan, and 430 responded by mail. In the section of the questionnaire about religious care, 382 responses were used for quantitative analysis, and 71 responses about religious care for qualitative analysis. In the current study, the 71 responses were grouped into families with and without a religion and were analyzed qualitatively. Families with a religion (N = 28) chose answers such as ''Instrumental care'' such as music or a religious event, ''Freedom of choice of kinds for religious care,'' ''Staff involvement of religious care,'' ''Meeting with a pastoral care workers,'' and ''Burden of offering a different kind of personal religion.'' In contrast, families without a religion (N = 44) chose answers such as ''Instrumental care,'' ''Freedom of choice whether patients receive religious care or not,'' ''Spiritual care,'' ''Not being able to accept religious care,'' and ''Burden of thinking about a religion and nuisance.'' These findings suggest that Japanese bereaved families with a religion generally regard religious care positively and prefer care through their own religion, whereas some families without a religion require religious care but some do not prefer it.

    Mounting evidence indicates that the gut microbiota are an important modifier of obesity and diabetes. However, so far there is no information on gut microbiota and "live gut bacteria" in the systemic circulation of Japanese patients with type 2 diabetes. Using a sensitive reverse transcription-quantitative PCR (RT-qPCR) method, we determined the composition of fecal gut microbiota in 50 Japanese patients with type 2 diabetes and 50 control subjects, and its association with various clinical parameters, including inflammatory markers. We also analyzed the presence of gut bacteria in blood samples. The counts of the Clostridium coccoides group, Atopobium cluster, and Prevotella (obligate anaerobes) were significantly lower (P blood at a significantly higher rate in diabetic patients than in control subjects (28% vs. 4%, P type 2 diabetes as assessed by RT-qPCR. The high rate of gut bacteria in the circulation suggests translocation of bacteria from the gut to the bloodstream. © 2014 by the American Diabetes Association.

    Full Text Available BACKGROUND: The avoidance of inhaled allergens or tobacco smoke has been known to have favorable effects on asthma control. However, it remains unclear whether other lifestyle-related factors are also related to asthma control. Therefore, a comprehensive study to examine the associations between various lifestyle factors and asthma control was conducted in Japanese asthmatic patients. METHODS: The study subjects included 437 stable asthmatic patients recruited from our outpatient clinic over a one-year period. A written, informed consent was obtained from each participant. Asthma control was assessed using the asthma control test (ACT, and a structured questionnaire was administered to obtain information regarding lifestyle factors, including tobacco smoking, alcohol drinking, physical exercise, and diet. Both bivariate and multivariate analyses were conducted. RESULTS: The proportions of total control (ACT = 25, well controlled (ACT = 20-24, and poorly controlled (ACT 3 metabolic equivalents-h/week, and raw vegetable intake (> 5 units/week were significantly associated with good asthma control by bivariate analysis. Younger age, periodical exercise, and raw vegetable intake were significantly associated with good asthma control by multiple linear regression analysis. CONCLUSIONS: Periodical exercise and raw vegetable intake are associated with good asthma control in Japanese patients.

Both bivariate and multivariate analyses were conducted. The proportions of total control (ACT = 25), well controlled (ACT = 20-24), and poorly controlled (ACT smoking status and alcohol drinking were not associated with asthma control. On the other hand, younger age (smoking, periodical exercise (> 3 metabolic equivalents-h/week), and raw vegetable intake (> 5 units/week) were significantly associated with good asthma control by bivariate analysis. Younger age, periodical exercise, and raw vegetable intake were significantly associated with good asthma control by multiple linear regression analysis. Periodical exercise and raw vegetable intake are associated with good asthma control in Japanese patients.

    Full Text Available Background: Percutaneous renal biopsy (PRB is essential for the diagnosis, prognosis, and management of children with unknown kidney disease. In this study, the safety and efficacy of PRB is investigated, and also the common etiologies of childhood kidney disease, based on histological findings. In addition, we explored the role of PRBs in the diagnosis of children who presented with persistent asymptomatic hematuria. Methods: By chart review, from July 2005 to July 2009, a total of 99 PRBs were performed on 91 children (43 girls and 48 boys; mean age, 10.9 ± 4.4 years under ultrasound (US guidance, by a doctor, using an automated 18-gauge biopsy needle following the same protocol, at a medical center in northern Taiwan. Results: The accuracy of the histological diagnosis was excellent. The most common post-biopsy complications were perirenal hematoma (11.1% and asymptomatic gross hematuria (3.0%, respectively. Nevertheless, these complications resolved spontaneously, and none had major bleeding episodes. Histological results showed that lupus nephritis, minimal change disease, and IgA nephropathy (IgAN could be the current leading causes of childhood kidney diseases in Taiwan. Conclusions: Automated ultrasound (US-guided PRB is a safe and reliable method of assessing childhood renal disease. A recent study shows that the presence of persistent asymptomatic isolated microhematuria in adolescents is a predictive marker of future end-stage renal disease. Hence, the emphasis of renal biopsy on children with persistent asymptomatic hematuria is beneficial for the early diagnosis of IgAN or other glomerulonephritis (GN, which tends toward progressive kidney disease in adulthood without prompt therapeutic intervention.

    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

    There is evidence that the stigma surrounding mental illness may be greater in Japan than elsewhere. However, few Japanese studies have focused on self-stigma (the internalization of social stigma), and few interventions to reduce self-stigma exist. To remedy this deficiency, we evaluated the efficacy of group cognitive-behavioral therapy (CBT) in reducing self-stigma and examined the relationship between cognitive restructuring and self-stigma. We administered a 10-session group CBT program to 46 Japanese outpatients with anxiety and depressive symptoms (36 men, 10 women; mean age=38.57 years, SD=8.33; 20 diagnosed with mood disorders; 24 with neurotic, stress-related, or somatoform disorders; and 2 with other disorders). A pretest-posttest design was used to examine the relationship between cognitive restructuring and self-stigma. Outcomes were measured using the Japanese versions of the Devaluation-Discrimination Scale, Dysfunctional Attitude Scale, Beck Depression Inventory-II, State-Trait Anxiety Inventory State-Form, and Rosenberg's Self Esteem Scale. Participants exhibited significant improvements in depression, anxiety, and maladjusted cognitive bias and reductions in self-stigma. Cognitive bias was significantly correlated with self-stigma. Group CBT is effective in improving both emotional symptoms and self-stigma in outpatients with anxiety and depressive symptoms. Reduction in self-stigma plays a mediating role in alleviating em
