    OBJECTIVES: A6 is a novel peptide that interferes with single-chain urokinase plasminogen activator activity and has shown anti-angiogenic, anti-migratory, and anti-invasive properties. We evaluated clinical efficacy and safety of subcutaneously administered A6 in women with epithelial ovarian...... cancer. METHODS: Women with epithelial ovarian, fallopian tube, or primary peritoneal cancer in clinical remission after first-line chemotherapy with 2 consecutive increases of CA125 values above normal but with no disease on physical examination or imaging studies were randomly assigned to receive daily...

    Over three decades have passed since the first report on the expression of CA125 by ovarian tumors. Since that time our understanding of ovarian cancer biology has changed significantly to the point that these tumors are now classified based on molecular phenotype and not purely on histological attributes. However, CA125 continues to be, with the recent exception of HE4, the only clinically reliable diagnostic marker for ovarian cancer. Many large-scale clinical trials have been conducted or are underway to determine potential use of serum CA125 levels as a screening modality or to distinguish between benign and malignant pelvic masses. CA125 is a peptide epitope of a 3-5 million Da mucin, MUC16. Here we provide an in-depth review of the literature to highlight the importance of CA125 as a prognostic and diagnostic marker for ovarian cancer. We focus on the increasing body of literature describing the biological role of MUC16 in the progression and metastasis of ovarian tumors. Finally, we consider previous and on-going efforts to develop therapeutic approaches to eradicate ovarian tumors by targeting MUC16. Even though CA125 is a crucial marker for ovarian cancer, the exact structural definition of this antigen continues to be elusive. The importance of MUC16/CA125 in the diagnosis, progression and therapy of ovarian cancer warrants the need for in-depth research on the biochemistry and biology of this mucin. A renewed focus on MUC16 is likely to culminate in novel and more efficient strategies for the detection and treatment of ovarian cancer.

    value in the detection of early ovarian cancer. At present, therefore, CA125, either alone or in combination with other modalities, cannot be recommended for screening for ovarian cancer in asymptomatic women outside the context of a randomized controlled trial. Preoperative levels in postmenopausal...... women, however, may aid the differentiation of benign and malignant pelvic masses. Serial levels during chemotherapy for ovarian cancer are useful for assessing response to treatment. Although serial monitoring following initial chemotherapy can lead to the early detection of recurrent disease......CA125 is currently the most widely used tumor marker for ovarian epithelial cancer. The aim of this article is to provide guidelines for the routine clinical use of CA125 in patients with ovarian cancer. Due to lack of sensitivity for stage I disease and lack of specificity, CA125 is of little...

  4. Meigs' syndrome with elevated CA 125: case report

    Full Text Available CONTEXT: Meigs' syndrome consists of a benign ovarian tumor accompanied by ascites and hydrothorax. Elevated serum CA 125 levels in postmenopausal women with solid adnexal masses, ascites and pleural effusion are highly suggestive for malignant ovarian tumor. However, patients with Meigs' syndrome can also have elevated serum CA 125 levels. The authors report a case of Meigs' syndrome with elevated CA 125 level. OBJECTIVE: This is a case report of Meigs' syndrome with elevated CA 125 level. CASE REPORT: A 65-year-old Brazilian woman had presented progressive dyspnea, weight loss and decline in general condition over the 7 months preceding admission to our service. In another hospital, the patient had been submitted to thoracic drainage due to pleural effusion. With recurrence of the pleural effusion and increase in abdominal volume due to ascites and a pelvic mass, the patient sought our service. Transvaginal ultrasound showed an extensive adnexal solid mass of 16.4 x 10.8 cm located in the pelvis without exact limits, and the serum CA 125 level was elevated. With a preoperative diagnosis of ovarian carcinoma, the patient was submitted to exploratory laparotomy, which revealed a left ovarian tumor. The frozen section diagnosis was thecoma. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed. The histology of the specimen confirmed the diagnosis of thecoma. The patient was asymptomatic with a normal serum CA 125 level 20 months after the operation.

However, the publications did not include detailed definitions, nor were they written to accommodate the new version of Response Evaluation Criteria In Solid Tumors (RECIST) criteria (version 1.1) now available....... Thus, we recommend that the definitions described later in detail are incorporated into clinical trial protocols to maintain consistency. The criteria for defining progression are now acceptable in clinical trials of recurrent disease as they have since been validated (Pujade-Lauraine, personal...... communication, 2010). The GCIG requests that data from all clinical trials using these definitions are made available to GCIG trial centers so that continual validation and improvement can be accomplished. These definitions were developed from analyzing patients receiving cytotoxic chemotherapy and have not yet...

    Purpose This trial was undertaken to 1) determine the feasibility of enrolling asymptomatic ovarian cancer patients with Ca-125 elevation to a trial with the PKCι inhibitor, auranofin, and 2) understand patients’ perceptions of Ca-125 monitoring. Methods Asymptomatic ovarian cancer patients with Ca-125 elevation received auranofin 3 mg orally twice/day and were evaluated. Patients participated in interviews about Ca-125 monitoring. Results Ten patients were enrolled in slightly over 6 months, exceeding our anticipated rate. Four manifested stable Ca-125 levels for 1 month or longer. The median progression-free survival was 2.8 months (95% confidence interval: 1.3, 3.8 months); auranofin was well tolerated. One patient had baseline and monthly Ca-125 levels of 5570, 6085, 3511, and 2230 units/mL, respectively, stopped auranofin because of radiographic progression at 3 months, and manifested an increase in Ca-125 to 7168 units/mL approximately 3 months later. Patient interviews revealed: 1) the important role of Ca-125 in cancer monitoring; 2) ardent advocacy for Ca-125 testing; and 3) evolution toward the Ca-125 assuming a life of its own. Conclusions This study showed feasibility; and patients favored Ca-125 monitoring. One patient had a decline in Ca-125, suggesting that PKCι inhibition merits further study in ovarian cancer.

    Full Text Available Introduction CA 125 determination started in 1981, when Bast et al. discovered monoclonal antibody OC-125 belonging to immunoglobulin G class (IgG1 using Köhler and Milstein's technique of hybridization. CA 125 antigen is produced in amniotic cells of the 7 week-old embryo, while in adults it can be detected in epithelium of most organs which originate from Müller ducts. The upper level of referent values for CA 125 in serum is 35 U/mL and can be seen in about 99% of healthy people. Application of tumor marker CA 125 in gynecological oncology More than 83% of patients with epithelial ovarian carcinoma have elevated values of CA 125 higher than 35 U/mL at the moment of diagnosing the disease. In cases of ovarian carcinoma, preoperatively determined values of CA 125 in serum are correlated with the extent of the expansion of the disease , histological type of tumor and degree of differentiation of malignant cells. Elevated values up to 65 U/mL in serum can also be found in other malignant tumors (pancreas, breast, colon, bladder, lungs, liver and in different benign diseases. The level of serum CA 125 after the surgery can indicate regression or progression of ovarian carcinoma in more than 90% of the patients who had had elevated values of CA125 prior to the surgery. Postoperative levels of CA 125 >35 U/mL in patients with no residual tumor and values >65 U/mL in those with residual tumor implants represent a separate prognostic factor in further course of the disease. Conclusion The importance of continuous determination of CA 125 tumor marker has to be adjusted to each single case.

    The presence of the tumor marker CA 125 was studied in different compartments of the human placenta. Levels of CA 125 in the cytosol of chorionic villi ranged from 27-17100 U/g (median 560 U/g). In the placental amnion and chorion concentrations ranged from 175-29000 U/g, median 1060 U/g and were not statistically different. In the umbilical cord values were significantly lower (range 44-7600 U/g; median 180 U/g). Maternal serum probes were above the upper limit of normal in all cases (range 48-500 U/ml; median 131 U/ml). Immunohistochemistry detected CA 125 exclusively within the amniotic cells of the placenta and the umbilical cord. This might be because CA 125 fixes more to insoluble structures in the amnion or because of contamination of chorionic villi with the underlying decidua.

    Objectives The present study investigated the clinical implications of pretreatment carbohydrate antigen 125 (CA-125) levels and CA-125 normalization in patients with ovarian clear cell carcinoma (CCC), and it provides useful information for the improvement of monitoring strategies for this lethal disease. Methods The medical records of patients with ovarian CCC who had undergone primary staging surgery or cytoreductive surgery followed by systemic chemotherapy were retrospectively reviewed. A range of clinico-pathological parameters were collected and examined. Results A total of 375 women were included in the analysis. FIGO stage (p < 0.001) was identified as the only significant prognostic factor for relapse. Residual tumor and advanced stage (p = 0.001 and p < 0.001, respectively) were identified as independent adverse factors for survival. The potential risk factors associated with elevated pretreatment CA-125 levels included advanced-stage disease, positive residual tumors and negative endometriosis (p < 0.001, p = 0.001 and p <0.001, respectively). Pretreatment CA-125 levels were not associated with relapse-free survival (RFS) or overall survival (OS) (p = 0.060 and p = 0.176, respectively). CA-125 normalization after chemotherapy exhibited a positive linear correlation with advanced stage (r = 0.97, p = 0.001) and residual tumor (r = 0.81, p = 0.027) and a negative relationship with 5-year RFS (r = −0.97, p = 0.002) and 5-year OS (r = −0.97, p= 0.001). Patients with CA-125 levels that normalized before cycle 2 of chemotherapy had a similar prognosis as patients whose CA-125 levels normalized prior to chemotherapy (RFS: p = 0.327; OS: p = 0.654). By contrast, patients with CA-125 levels that normalized after cycle 2 of chemotherapy or never normalized were significantly more likely to experience disease progression. Conclusions Pretreatment CA-125 levels are not very useful for predicting clinical outcome. CA-125 levels following treatment are a valid

    Inadequacy of collateral arterial flow is the major risk factor for hemispheric infarction in association with spontaneous occlusion of the ipsilateral carotid artery. This prospective study was designed to measure the adaptation of collateral cerebral circulation through the circle of Willis in patients in whom a unilateral carotid stenosis of hemodynamic consequence develops asymptomatically. The collateral cerebral potential is assessed by ocular pneumoplethysmography (OPG) during proximal common carotid artery compression, measuring the collateral ophthalmic artery pressure (COAP). During an average follow-up of almost 3 years (maximum more than 7 years), 45 patients showed asymptomatic development of a unilateral hemodynamically significant carotid stenosis according to OPG evidence. In these patients the mean index COAP/brachial artery pressure did not change on the side of stenosis progression (p greater than 0.05). The developed carotid stenosis had only reduced collateral circulation to the contralateral hemisphere. The risk of inadequate collateral cerebral circulation remained during progression of asymptomatic extracranial arterial obstructive disease.

    We evaluated the utility of a single CA 125 measurement in combination with transvaginal sonography for early detection of ovarian and endometrial cancer in asymptomatic postmenopausal women. A sample of peripheral blood was taken from 1291 apparently healthy postmenopausal women, who were examined by conventional and color Doppler ultrasound for early detection of ovarian and endometrial cancer. Serum CA 125 was determined in all samples 3 years later by the IMx CA 125 assay (Abbott Laboratories, Abbott Park, IL). The cutoff level based on the 99th percentile was 30 U/ml. Elevated values were controlled by repeat sonography and an additional determination of CA 125. Record linkage with the files of the Finnish Cancer Registry was performed 3 1/2 years after the primary sonographic screening. The mean CA 125 concentration was 8.1 U/ml (range 0-1410 U/ml). Fourteen of the 1291 women had a CA 125 level greater than 30 U/ml. None of these had signs of either endometrial or ovarian malignancy in the primary sonography screening. Among the other women three cases of endometrial carcinoma (all stage Ib) and one ovarian carcinoma (stage Ia with borderline malignancy) were detected by sonography. All these patients had a CA 125 value <30 U/ml, the mean value being 11.4 U/ml (range 7.5-16.7 U/ml). During follow-up of 3.5 years, one stage Ia ovarian carcinoma, one abdominal carcinomatosis, and two endometrial carcinomas (both stage Ib) were diagnosed. In these patients the mean value for CA 125 was 12.7 U/ml (range 2.5-30.9 U/ml) at the primary sonography screening. A single CA 125 measurement provides no advantage in the early detection of ovarian and endometrial cancer in asymptomatic postmenopausal women compared with transvaginal sonography. The vast majority of women with an elevated CA 125 value have some reason other than an ovarian or endometrial malignancy for this finding.

    In a study of 71 patients with malignant ovarian tumors serum levels of CA-125, C-reactive protein (CRP), alpha-1-antitrypsin and coeruloplasmin were analysed. In contrast to the tumor-free group significantly higher values of CA-125, CRP and alpha-1-antitrypsin were found in the group with recurrent disease. However, the serum-concentrations of coeruloplasmin remained unchanged in both groups. In the group with progressive disease the median values of CA-125 were greater than 65 U/ml and of CRP greater than 12 micron/ml, respectively. The median serum concentrations of alpha-1-antitrypsin (2 to 4 mg/ml) and coeruloplasmin (150 to 600 ng/ml) did not reach their cut-off levels. Beside CA-125 the analysis of CRP and alpha-1-antitrypsin is an additional helpful procedure for the monitoring of patients with malignant ovarian tumors.

    Full Text Available An elevated serum CA125 level in association with a pelvic mass, pleural effusion, and massive ascites usually signifies a dismal prognosis in a postmenopausal woman. However, surgery and histopathological examination are required for the correct diagnosis and treatment, since an elevated CA125 level can be falsely positive for ovarian malignancy. We present a case of Meigs’ syndrome due to right ovarian fibroma with elevated CA125 level in a postmenopausal woman.

    The monoclonal antibody (mAb) OC 125 reacts with an antigen on human ovarian carcinoma (OVCA) cells that is also shed into the body fluids and can be detected in patients' sera and/or ascites with a radioimmunometric assay. For the present study, serum CA 125 levels of patients (n = 36) with different stages of OVCA were investigated. Serum levels seem to correlate with tumor burden. In stages I and II (n = 12), 33% of patients were CA 125 positive, whereas 70% of stage III and IV patients (n = 24) were CA 125 positive. Mean serum levels were in 93 U/ml (stages I, II) and 279 U/ml (stages III, IV). CA 125 levels in ascites and in pleural effusions were manyfold higher than serum levels of the same patients (P less than 0.0001). Immunohistochemical investigations of CA 125 in different ovarian tumors (n = 91) revealed that 85% of malignant and 75% of borderline serous cystadenocarcinomas had detectable CA 125 surface expression. Furthermore, 71% of benign tumors showed the CA 125 epitope, whereas mucinous tumors were negative for this marker. One of six ovarian cancer cell lines was CA 125 positive, whereas in 6 of 11 patients, ascites-derived ovarian cancer cells (fresh and gradient isolated) were positive for this marker. The proportion of positive cells ranged from 10 to 90% in these samples. Intraperitoneal recombinant interferon-gamma (rIFN-gamma) therapy resulted in an increase in the number of cells reacting with CA 125. The results of monitoring in patients receiving different therapeutic regimens and/or agents demonstrate the usefulness of this marker.

    Three hundred and ninety-five CA 125 serum values of 72 patients with ovarian cancer were correlated with the clinical status. With a threshold value of 35 U/ml we found true negative values in 85% and true positive values in 93%. No correlation between preoperative CA 125 values and tumor stage was noted at primary surgery. During follow-up, 17 women had marker values between 35 and 65 U/ml. Three out of 7 women in clinical remission showed a value greater than 65 U/ml at subsequent follow-up and developed recurrent disease. In 8 patients out of 20 re-laparotomies, tumors with a maximum diameter of greater than 2 cm were confirmed with a preoperative serum CA 125 concentration greater than 65 U/ml. Two out of 3 patients with a tumor diameter less than 2 cm at re-laparotomy revealed CA 125 serum concentrations less than 35 U/ml. A false positive CA 125 value was found in one patient without demonstrable active disease. The calculated doubling time of the CA 125 values ranged between 23 and 173 days; the median value was 67 +/- 47 days. After 6.2 +/- 1.3 doubling times death ensued.

    The prognostic significance of preoperative serum CA125, CA19-9 and CEA in gastric carcinoma (GC) has been widely reported and is still under debate. Here, we evaluated the prognostic significance of preoperative serum CA125, CA19-9 and CEA in patients with GC. 1692 patients with GC who underwent gastrectomy were divided into the training (from January 2005 to December 2011, n = 1024) and the validation (from January 2012 to December 2013, n = 668) cohorts. Positive groups of CA125 (> 13.72 U/ml), CA19-9 (> 23.36 U/ml) and CEA (> 4.28 ng/ml) were significantly associated with more advanced clinicopathological traits and worse outcomes than that of negative groups (all P < 0.01). In Cox regression analysis, tumor size (P < 0.001, P = 0.005), pTNM stage (P < 0.001, P < 0.001) and CA125 (P = 0.026, P = 0.005) were independent prognostic factors both in two cohorts. Nomograms of these two cohorts based on the number of positive serum tumor markers (NPTM) were more accurate in prognostic prediction than TNM stage alone. Our findings suggested that elevated preoperative serum CA125, CA19-9 and CEA were associated with more advanced clinicopathological traits and less favorable outcomes. In addition, CA125 as an independent prognostic factor should be further investigated. Nomogram based on NPTM could accurately predict the prognosis of GC patients. PMID:27097114

    The CA125 biomarker assay plays an important role in the diagnosis and management of primary invasive epithelial ovarian/tubal cancer (iEOC). However, a fundamental problem with CA125 is that it is not cancer-specific and may be elevated in benign gynecological conditions such as benign ovarian...... for profiling specific aberrant glycoforms, such as Neu5Aca2,6GalNAc (STn) and GalNAc (Tn), present on CA125 (MUC16) and CA15-3 (MUC1). In a blinded cohort study of patients with an elevated CA125 levels (30-500 kU/L) and a pelvic mass from the UK Ovarian Cancer Population Study (UKOPS), we measured STn-CA125......, ST-CA125 and STn-CA15-3. The combined glycoform profile was able to distinguish benign ovarian neoplasms from invasive epithelial ovarian/tubule cancer (iEOCs) with a specificity of 61.1% at 90% sensitivity. The findings suggest that microarray glycoprofiling could improve differential diagnosis...

    Objective: To explore clinical and laboratory features and significance of detecting serum carbohydrate antigen 125 (CA125) in immunoglobulin E (IgE) multiple myeloma. Methods: We reported the clinical findings of a male patient with IgE myeloma and elevated level of serum CA125 and reviewed the literature. Results: Laboratory tests of this patient on admission showed extremely high serum IgE and CA125, a bone marrow aspirate revealed abnormal plasma cells (38.4% of nucleated cells: 16.4% mature and 22% atypical), and in bone marrow biopsy, immunoperoxidase staining showed positive cytoplasmic staining for IgE and κ light chain within the vast majority of plasma cells. Computed tomography (CT) bone scans indicated wedge shape change and compressive fracture of thoracic vertebrae, and emission computed tomography (ECT) discovered multiple punctiform aggregation of radiation in both cervical ribs and spine. The serum IgE and CA125 gradually decreased to normal limits after eight cycles of chemotherapy. This patient is alive well with an 18-month complete remission. Conclusion: We reported the first case of IgE myeloma with elevated level of serum CA125. To further evaluate clinical characteristics and significance of CA125 in IgE myeloma, more cases are needed.

    The purpose of this study is to evaluate whether fluorodeoxyglucose (FDG) uptake of the large arteries can predict coronary artery calcium (CAC) progression in asymptomatic individuals. Ninety-six asymptomatic individuals who underwent FDG positron emission tomography (PET) and CAC scoring on the same day for health screening and follow-up CAC scoring ≥1 year after baseline studies (mean 4.3 years) were included. Vascular FDG uptake was measured and corrected for blood pool activity to obtain peak and average target-to-blood pool ratios (TBRpeak and TBRavg, respectively) for the carotid arteries, and ascending and abdominal aorta. CAC scores at baseline and follow-up of each individual were measured and absolute CAC change (ΔCAC), annual CAC change (ΔCAC/year), and annual CAC change rate (ΔCAC%/year) were calculated. CAC progression was defined as ΔCAC >0 for individuals with negative baseline CAC; ΔCAC/year ≥10 for those with baseline CAC of 0progression. Thirty-one subjects showed CAC progression. CAC-progressors showed significantly higher TBRpeak and TBRavg as compared to non-CAC-progressors for all three arteries. TBRpeak of the abdominal aorta was significantly associated with CAC progression in multivariate analysis, with age and baseline CAC. A higher TBRpeak of the abdominal aorta (≥2.11) was associated with CAC progression among subjects with negative baseline CAC only. In subjects with positive baseline CAC, only the amount of baseline CAC was significantly associated with CAC progression. However, the positive predictive value of the TBRpeak of the abdominal aorta was <40 % when age was <58 or baseline CAC was negative. Higher FDG uptake of the large arteries is

    Full Text Available Introduction: Primary ovarian neoplasms exhibit a wide range of histopathological aspects, and tumors with epithelial differentiation are the most frequent. Among the malignant tumors, the most common histological type corresponds to serous adenocarcinoma, whose diagnosis is established in advanced stages of the disease in approximately 75% of the patients. Tumor marker CA 125 represents a glycoprotein synthesized mainly by neoplastic cells with epithelial differentiation, and its serum level seems to be associated with the biological potential of these lesions. Objective: To estimate the association between serum levels of CA 125 and the degree of differentiation in primary ovarian neoplasms. Method: Sixty distinct cases of primary ovarian tumors were selected, previously analyzed at the Laboratory of Pathology of the Hospital Complex of Universidade Luterana do Brasil (Ulbra, between 2005 and 2010, from patients undergoing concomitant analysis of CA 125. In each case, age, tumor size, histological type, degree of differentiation, presence of necrosis and tumor invasion of the albuginea or extraovarian tissues, pathological stage and serum CA 125 were determined. Results: A statistically significant relationship between CA 125 levels and histological grade (p = 0.001, age (p = 0.009, biological behavior of the tumor (malignant or benign - p = 0.002 and extraovarian invasion (p = 0.005 was found. No relationship between CA 125 levels and tumor size (p = 0.1006 and pathologic stage (p = 0.1 was determined. Histologic grade was associated with the presence of necrosis (p = 0.001, extraovarian invasion (p = 0.009 and tumor size (p = 0.008. Conclusion: In the present study, serum levels of CA 125 were associated with histological grade in primary ovarian neoplasms, especially in high-grade malignant tumors, suggesting that high levels of this glycoprotein are associated with lesions of more aggressive biological behavior.

    Full Text Available Objective. This study assesses the role of preoperative serum CA125 levels in the planning treatment options for women diagnosed with uterine cancer. Material and Method. Ninety five consecutive patients diagnosed with uterine cancer during a four-year period were identified. Age ranged from 35 to 89 years with a mean age of 69 years. The preoperative CA125 levels were dichotomised at 28 U/mL (using ROC analysis to identify the best discriminating threshold for 5-year survival. This level was then correlated with preoperative prognostic indicators: patient age, tumour grade, and histopathological tumour cell type. Survival data was plotted using Kaplan-Meier curves and analysed using the log-rank test. Univariate and multivariate analysis were performed to identify the predictors of overall survival. Results. The mean age of patients was 69 years (range: 35–89. On univariate analysis, the use of preoperative CA125 levels of greater or less than 28 U/mL correlated significantly with age (P=0.01, the grade of disease (P=0.02 and unfavourable tissue type (P=0.03. This threshold CA125 level had a sensitivity of 75%, specificity of 76%, positive predictive value of 35% and negative predicative value of 96.25%, and a likelihood ratio of 3.12 for predicting nodal disease. Using a threshold of preoperative CA125 level of 28 U/mL (area under curve: 0.60 was also a significant predictor of 5-year survival (log-rank test, P=0.01. Using Cox multivariate survival analysis to identify predictive preoperative factors overall, unfavourable cell type was the strongest predictor of survival (Chi square = 36.5, df = 4, and P=0.001, followed by preoperative CA125 level (CA125 > 28 U/mL, P=0.011 and unfavourable preoperative grade (P=0.017. Amongst patients with a favourable histological tissue type (endometrioid, preoperative CA125 levels predicted overall survival (Chi square = 6.039, df = 2, P=0.02; however unfavourable preoperative

    A mucin-like carcinoma associated antigen (MCA), which is recognized by the monoclonal antibody b-12, was found to be elevated in sera of breast cancer patients. Since an immunohistochemical reaction of the monoclonal antibody b-12 was found in epithelial tumors of the ovary we investigated MCA serum levels in 50 patients with ovarian cancer (mean age 59 years, range 31-81 years). In addition, CA 125, CA 19-9 and CEA were determined to compare sensitivity, specificity and the predictive value of the positive test of each parameter used in this study. Blood samples were obtained in 20 patients with progressive disease and in 30 patients during disease free intervals. The MCA serum levels of patients with progressive ovarian cancer (mean +/- SD: 14.7 +/- 14.6 U/ml) did not differ significantly from those of patients in remission (mean +/- SD: 8.2 +/- 5.3 U/ml) or from values of a healthy control group (mean +/- SD: 7.7 +/- 3.8 U/ml, n = 70). Women with progressive disease displayed significantly higher CA 125 (p less than 0.0001) and CEA (p less than 0.0063) serum levels than patients in remission. No significant difference was found for CA 19-9 in patients with ovarian cancer, irrespective of the clinical status. Considering marker surge and tumor progression, the highest sensitivity was found for CA 125 (75%). Sensitivities of the other markers were significantly lower and reached only 25-35%. The predictive value of elevated marker levels as well as specificity of the marker substances were similar. Sensitivity could be extended to 90% if elevation of CA 125, CA 19-9, CEA and MCA were taken into consideration, however specificity was lowered by using this marker combination.

    During the postmenopausal years, the ovaries become atrophic. The incidence ovarian neoplasm increases with age. A suspicious or persistent complex mass and increased tumor marker like CA125 and OVA1 in post-menopausal woman requires surgical evaluation. The traditional diagnostic tools for ovarian tumors are bimanual examination, pelvic ultrasound and measuring serum biomarker like CA125 level, but these methods have low specificity and sensitivity. Now-a-days the role of some tumor marker such as OVA1in the management of ovarian tumor has been approved by FDA. [Int J Reprod Contracept Obstet Gynecol 2014; 3(1.000: 236-238

    We report a case of ovarian fibroma with marked ascites and elevated serum CA-125 levels in a young girl. Ovarian fibromas are rare in children. They usually present as a solid mass and may be associated with ascites and elevated serum CA-125 levels. Because of their solid nature and these associations, they can be mistaken for a malignant tumor, resulting in unnecessary oophorectomy. Ovarian fibromas are benign neoplasms, and the prognosis is extremely good. Surgical management should be an ovarian-sparing tumor excision. Although uncommon in pediatric patients, ovarian fibromas should be included in the differential diagnosis of ovarian mass in children.

    The presence of a pelvic mass in a patient with an elevated serum CA-125 suggests the possibility of a gynecologic malignancy. However, an increasing number of nonneoplastic causes of elevated serum CA-125 have been reported. This is the first report of a pelvic hematoma associated with elevated serum CA-125. Two weeks following cardiac catheterization at time of myocardial infarction a patient was noted to have a complex pelvic mass on ultrasound and serum CA-125 of 53 units per milliliter. Abdominal-pelvic CT-scan showed a small left pleural effusion, minimal ascites, left lower quadrant abdominal wall masses consistent with omental metastases, and a 9.4 x 10.3 x 9.0-cm complex left adnexal mass. At exploratory laparotomy a large organized hematoma in the left paravesical space was adherent to both the left external iliac artery and the left bladder wall. This mass could have been managed expectantly with percutaneous aspiration if a nonmalignant diagnosis had been more strongly considered.

    We aimed to estimate the prevalence of combined pulmonary fibrosis and emphysema (CPFE) and describe the follow-up CT results of CPFE in asymptomatic smokers. This study was retrospective, and approved by an institutional review board. CT images of 2,016 current or previous male smokers who underwent low-dose chest CT at our healthcare centre were reviewed. Quantitative CT analysis was used to assess the extent of emphysema, and two radiologists visually analyzed the extent of fibrosis. Changes in fibrosis (no change, improvement, or progression) were evaluated on follow-up CT imaging (n = 42). Kaplan-Meier survival analysis, multivariate logistic regression and its ROC curve were used for survival and progression analysis. The prevalence of CPFE among asymptomatic male smokers was 3.1 % (63/2,016). The median follow-up period was 50.4 months, and 72.7 % (16/22) of continued smoker had progressing fibrosis on follow-up CT. CPFE progressed more rapidly in continuous smokers than in former smokers (p = 0.002). The 3.5-year follow-up period after initial CPFE diagnosis maximized the sum of sensitivity and specificity of CPFE progression prediction in continuous smokers. The prevalence of CPFE turned out not to be inconsiderable in asymptomatic male smokers, but serial CT follow-up would be helpful in recognizing disease progression. (orig.)

    Full Text Available CA125 is a mucin glycoprotein whose concentration in serum correlates with a woman’s risk of developing ovarian cancer and also indicates response to therapy in diagnosed patients. Accurate detection of this large, complex protein in patient samples is of great clinical relevance. We suggest that powerful new diagnostic tools may be enabled by the development of nucleic acid aptamers with affinity for CA125. Here, we report on our use of One-Pot SELEX to isolate single-stranded DNA aptamers with affinity for CA125, followed by high-throughput sequencing of the selected oligonucleotides. This data-rich approach, combined with bioinformatics tools, enabled the entire selection process to be characterized. Using fluorescence anisotropy and affinity probe capillary electrophoresis, the binding affinities of four aptamer candidates were evaluated. Two aptamers, CA125_1 and CA125_12, both without primers, were found to bind to clinically relevant concentrations of the protein target. Binding was differently influenced by the presence of Mg2+ ions, being required for binding of CA125_1 and abrogating binding of CA125_12. In conclusion, One-Pot SELEX was found to be a promising selection method that yielded DNA aptamers to a clinically important protein target.

    Full Text Available OBJECTIVE: Dialysate concentrations of CA-125 reflect the mesothelial cell mass. In patients with peritoneal dialysis ultrafiltration failure, low concentrations of CA-125 have been demonstrated. Statins have anti-inflammatory properties which may be of value in modulating responses to injury. In this study, the lipid-lowering effect of atorvastatin and its effects on the CA-125 levels were evaluated. MATERIALS and METHODS: The 100 patients included in the study were followed with CRF in the CAPD program. The patients were divided into two groups as those who used atorvastatin (group 1, n=60 and the control group (group 2, n=40. All patients were evaluated before treatment and 6 months later for serum total cholesterol, LDL, HDL, TG, CRP, and peritoneal effluent was analyzed for interleukin-6, and CA-125 levels. RESULTS: In group 1 patients, serum CRP and dialysate IL-6 values decreased and the dialysate CA- 125 level increased (p<0.001, whereas there was no change in the group 2 control patients. CONCLUSION: Atorvastatin use in patients with markers of inflammation caused decreased levels of CRP and IL-6, and the anti-inflammatory effects of statins may have played a role. The increased CA-125 levels in patients in group 1 may also be related to the anti-inflammatory effects in addition to the antihyperlipidemic effects.

    Effective treatment of ovarian cancer depends upon the early detection of the malignancy. Here, we report on the development of a new nanostructured immunosensor for early detection of cancer antigen 125 (CA-125). A gold electrode was modified with mercaptopropionic acid (MPA), and then consecutively conjugated with silica coated gold nanoparticles (AuNP@SiO2), CdSe quantum dots (QDs) and anti-CA-125 monoclonal antibody (mAb). The engineered MPA|AuNP@SiO2|QD|mAb immunosensor was characterised using transmission electron microscopy (TEM), atomic force microscopy (AFM), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Successive conjugation of AuNP@SiO2, CdSe QD and anti-CA-125 mAb onto the gold electrode resulted in sensitive detection of CA-125 with a limit of detection (LOD) of 0.0016 U mL-1 and a linear detection range (LDR) of 0-0.1 U mL-1. Based on the high sensitivity and specificity of the immunosensor, we propose this highly stable and reproducible biosensor for the early detection of CA-125.Effective treatment of ovarian cancer depends upon the early detection of the malignancy.

    In medicine, Meigs' syndrome is the triad of ascites, pleural effusion, and benign ovarian tumor (fibroma, Brenner tumour, and occasionally granulosa cell tumour). It resolves after the resection of the tumor. Because the transdiaphragmatic lymphatic channels are larger in diameter on the right, the pleural effusion is classically on the right side. The etiologies of the ascites and pleural effusion are poorly understood. Atypical Meigs' syndrome,characterized by a benign pelvic mass with right-sided pleural effusion but without ascites, can also occur. As in Meigs syndrome, pleural effusion resolves after removal of the pelvic mass. The authors would like to share their own experience of a case of Meigs' syndrome associated with an enormous ovarian fibroma and elevated Ca-125.

    Full Text Available The aim of this study was to assess the diagnostic values of three breast tumor markers (i.e., CEA, CA153 and CA125 in milk and nipple discharge in the prediction of different breast diseases diagnoses.Three hundred thirty-six patients (96 breast cancer and 240 benign disease patients with nipple discharge and a control group of 56 healthy parturient participants were enrolled in the present study. Nipple discharge samples were preoperatively collected from the patients, and milk was collected from the colostrum of the parturient participants. The samples were assayed for the CEA, CA153 and CA125 levels. Cutoff values were determined for the detection of breast diseases using ROC curves.The levels of CEA, CA153 and CA125 were significantly different between the nipple discharge and the milk (all ps < 0.001. In the nipple discharge, the CEA and CA153 levels in the breast cancer group were significantly greater than those in the benign group (all ps < 0.001, and cutoff values of 263.3 ng/mL and 1235.3 U/mL, respectively, were established. However, the expression of CA125 did not differ significantly between the breast cancer and benign groups.Differences in the apparent expression levels of CEA, CA153 and CA125 in patients with nipple discharge and healthy persons were validated. The present data suggest that CEA and CA153 might potentially be useful in the differential diagnoses of benign tumors and breast cancer. CA125 did not seem to be useful for breast cancer detection.

    Background The aim of this study was to evaluate the relationship between ultrasonographic findings and serum progesterone and cancer antigen-125 (CA-125) levels in threatened miscarriage and to predict pregnancy outcome. Materials and Methods In a prospective comparative case-control study, serum CA-125 and progesterone levels were measured for 100 pregnant women with threatened miscarriage who attended the outpatient clinic or the causality department of Obstetrics and Gynecology at Kasr El-Aini Hospital, Giza, Egypt, during the period from March 2013 to October 2013. Ultrasound was performed for fetal viability, crown-rump length (CRL), gestational sac diameter (GSD) and fetal heart rate (FHR). The patients were followed up and divided into two groups based on the outcome: 20 women who miscarried (group 1), and 80 women who continued pregnancy (group 2). The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall accuracy were tested for CA-125 and progesterone levels in prediction of the pregnancy outcome. Correlation of these chemical markers with the ultrasound markers was also examined. Results In the group that miscarried, CA-125 level was significantly higher (P<0.001) and serum progesterone level was significantly lower (P<0.001). For prediction of the outcome of pregnancy, the cut-off limit of 31.2 IU/ml for CA-125 level yielded sensitivity, specificity and an overall accuracy of 96.2, 100 and 99.4% respectively. The cut-off limit of 11.5 ng/ml for progesterone level yielded sensitivity, specificity and an overall accuracy of 97.5, 100 and 99.8% respectively. CA-125 level had a negative correlation with progesterone level and FHR levels (r=-0.716, P<0.001) and (r=-0.414, P<0.001) respectively. Serum progesterone level correlated with GSD (r=0.521, P<0.001) and with CRL (r=0.407, P<0.001) and FHR (r=0.363, P<0.001). CA-125 level was significantly higher in the group that showed hematoma as compared with the

    Tumor markers CA 125, CA 19-9, and carcinoembryonic antigen (CEA) were detected by immunohistochemistry in paraffin embedded tissue samples obtained from two different locations in 35 ovarian tumors. In addition, serum concentrations of these tumor markers were measured before cytoreductive surgery. The staining reaction was heterogeneous in different parts of the tumor as well as within the parenchyma. Of the marker positive tumors, a staining reaction was observed in both tissue samples in only 10 of 22 cases for CA 125, in eight of 13 cases for CEA, and in three of eight cases for CA 19-9. Eighty-one percent of the patients whose tumor was positive for CA 125 also showed elevated serum levels of this marker. A poor correlation was found between tissue and circulating CA 19-9 levels. CEA was detected in 28% of the tumors and seemed to be valuable only for monitoring in rare cases of ovarian cancer. For purposes of selecting a marker for monitoring of patients with ovarian carcinoma, immunohistochemistry has a predictive value for CA 125 only. In order to better define the marker expressed in a tumor, it is necessary to examine at least two samples of different parts of the malignant tissue.

    Semiconductor quantum dots (QDs) offer several advantages over organic dyes in fluorescence-imaging applications, such as higher quantum yield, exceptional photostability, and a narrow, tunable,and symmetric emission spectrum. To explore whether QDs could specifically and effectively label tumor markers and be used in immunohistochemistry as a novel type of fluorescent probe, we used quantum dots with maximum emission wavelength 605 nm (QD605) to detect the ovarian carcinoma marker CA125 in specimens of different types (fixed cells, tissue sections, and xenograft piece). Additionally, we compared the photostability of QD signals with that of a conventional organic dye, FITC. All labeling signals of QDs were found to be more specific and brighter than those of FITC. Moreover, the QDs exhibited exceptional photostability during continuous illumination for 1 h by a high-intensity laser (Ar laser power 100 mW) at 488 nm, while the FITC signals faded very quickly and became undetectable after 24 min of illumination. These results indicate that QD-based probes can offer substantial advantages over existing fluorophores in many applications, and can be used effectively in immunohistochemistry as a novel class of fluorescent probes.

    One concept for immune therapy of cancer involves induction of antigen mimic antibodies to trigger the immune response against tumor cells. Anti-idiotypic antibodies directed against the antigen-binding site of antibodies specific for tumor antigen may functionally and even structurally mimic antigen and induce anti-anti-idiotypic immune response. Monoclonal antibody WJ02 is one of such anti-idiotypic antibodies, which contains internal image of CA125. In order to improve the immunospecificity of mAb WJ02, we constructed a single chain of mAb WJ02 in Vl-linker-Vh orientation. The scFv-WJ02 could be expressed and secreted in the recombinant Pichia pastoris system. The secreted scFv protein with a molecular weight of 30 kD retained the biological activity of mAb WJ02, which was proved by a direct binding assay and inhibition experiment. Our results indicated that the scFv-WJ02 could be used as a possible tool for idiotypic therapy against ovarian cancer, which might enhance the possibility of eliminating nonspecific responses induced by mAb WJ02.

    CA 125 and cancer-associated serum antigen (CASA) were measured prior to second-look laparotomy (SLL) to investigate their predictive and prognostic values in 93 patients treated for epithelial ovarian cancer FIGO stage II, III, or IV. Residual tumor was diagnosed at the SLL in 58 patients (62%). The optimal cutoff level was 15 U/ml for CA 125 and 8 U/ml for CASA. Using these levels, the sensitivity for detection of residual tumor was 40% for CA 125 and 22% for CASA. The combined use of the markers resulted in a sensitivity of 47% (diagnostic gain 6.9%; 95% confidence interval (CI), 0.14-13.44%). Microscopic tumor volumes were equally diagnosed by CASA and CA 125. The independent prognostic value of CA 125 (RR = 2.6; 95% CI, 2.0-3.2) and CASA (RR = 2.2; CI, 1.5-2.9) was established by means of Cox regression analysis of the covariation between survival, age, FIGO stage, histopathology, tumor grade, and bulk of residual tumor at the primary operation and CA 125 and CASA before the SLL. In conclusion, we found that CASA could supplement CA 125 measurement prior to SLL and reduce the number of SLLs. Furthermore, CASA had an independent prognostic value for survival which may be used together with other information in the planning of further treatment of the individual patient.

  6. Preoperative CA125 and fibrinogen in patients with endometrial cancer: a risk model for predicting lymphovascular space invasion

    Science.gov (United States)

    2017-01-01

    Objective The aim of this study was to build a model to predict the risk of lymphovascular space invasion (LVSI) in women with endometrial cancer (EC). Methods From December 2010 to June 2013, 211 patients with EC undergoing surgery at Shanghai First Maternity and Infant Hospital were enrolled in this retrospective study. Those patients were divided into a positive LVSI group and a negative LVSI group. The clinical and pathological characteristics were compared between the two groups; logistic regression was used to explore risk factors associated with LVSI occurrence. The threshold values of significant factors were calculated to build a risk model and predict LVSI. Results There were 190 patients who were negative for LVSI and 21 patients were positive for LVSI out of 211 patients with EC. It was found that tumor grade, depth of myometrial invasion, number of pelvic lymph nodes, and International Federation of Gynecology and Obstetrics (FIGO) stage (p0.05) were not associated with LVSI. Receiver operating characteristic (ROC) curves revealed that the threshold values of the following factors were correlated with positive LVSI: 28.1 U/mL of CA19-9, 21.2 U/mL of CA125, 2.58 mg/dL of fibrinogen (Fn), 1.84 U/mL of carcinoembryonic antigen (CEA) and (6.35×109)/L of white blood cell (WBC). Logistic regression analysis indicated that CA125 ≥21.2 (p=0.032) and Fn ≥2.58 mg/dL (p=0.014) were significantly associated with LVSI. Conclusion Positive LVSI could be predicted by CA125 ≥21.2 U/mL and Fn ≥2.58 mg/dL in women with EC. It could help gynecologists better adapt surgical staging and adjuvant therapies. PMID:27894164

    Full Text Available Abstract Objectives The ovarian tumor marker CA125 is expressed on human MUC16, a cell surface bound mucin that is also shed by proteolytic cleavage. Human MUC16 is overexpressed by ovarian cancer cells. MUC16 facilitates the binding of ovarian tumor cells to mesothelial cells lining the peritoneal cavity. Additionally, MUC16 also is a potent inhibitor of natural killer cell mediated anti-tumor cytotoxic responses. Extensive studies using human as well as murine ovarian tumor cell models are required to clearly define the function of MUC16 in the progression of ovarian tumors. The major objective of this study was to determine if the murine ovarian tumor cells, MOVCAR, express Muc16 and to characterize antibodies that recognize this mucin. Methods RT-PCR analysis was used for detecting the Muc16 message and size exclusion column chromatography for isolating Muc16 produced by MOVCAR cells. Soluble and cell-associated murine Muc16 were analyzed, respectively, by Western blotting and flow cytometry assays using a new panel of antibodies. The presence of N-linked oligosaccharides on murine Muc16 was determined by ConA chromatography. Results We demonstrate that murine Muc16 is expressed by mouse ovarian cancer cells as an ~250 kDa glycoprotein that carries both O-linked and N-linked oligosaccharides. In contrast to human MUC16, the murine ortholog is primarily released from the cells and cannot be detected on the cell surface. Since the released murine Muc16 is not detected by conventional anti-CA125 assays, we have for the first time identified a panel of anti-human MUC16 antibodies that also recognizes the murine counterpart. Conclusion The antibodies identified in this study can be used in future purification of murine Muc16 and exhaustive study of its properties. Furthermore, the initial identification and characterization of murine Muc16 is a vital preliminary step in the development of effective murine models of human ovarian cancer. These

    Objective:To explore the clinical value of serum β-HCG, P, CA125, and color Doppler ultrasound in the early diagnosis of ectopic pregnancy (EP). Methods:A total of 50 patients with EP who were admitted in our hospital from September, 2014 to September, 2015 were included in the study and served as the observation group, while 50 normal pregnant women were served as the control group. A volume of 5 mL of fasting elbow venous blood the day on admission in the two groups was extracted, and then was centrifuged for serum. The chemiluminescence immunoassay was used to detect the levels of serum β-HCG, P, and CA125. After 48h,β-HCG level was detected again. The vaginal color Doppler diasonograph was used to detect the changes of RI and PSV. The blood supply of LH was observed. Results:The levels of serumβ-HCG, P, and CA125 in the observation group were significantly lower than those in the control group (P<0.05). When β-HCG<2 000 IU/L, after 48 h, β-HCG level was doubled in 3 cases (6.0%) in the observation group, while in 49 cases (98.0%) in the control group, and the differences between the two groups were not statistically significant (P<0.05). RI in the observation group was significantly higher than that in the control group, while PSV was significantly lower than that in the control group (P<0.05). Blood supply in the observation group was in a half ring shape, accounting for 58.0%;in the control group was in a ring shape, accounting for 70.0%, and the difference was statistically significant (P<0.05). Conclusions:Determination of the levels of serumβ-HCG, P, and CA125 in the pregnant women, in combined with the vaginal color Doppler ultrasound detection of RI and PSV, can contribute to distinguish the normal intrauterine pregnancy with EP and prevent the misdiagnosis, which can provide an accurate reference value for the early diagnosis and timely treatment of EP, and can be used as an ideal method for the diagnosis of EP.

    Full Text Available The purpose of this analysis was to evaluate if serum levels of potential tumor markers for the diagnosis of malignant mesothelioma and lung cancer are affected by confounding factors in a surveillance cohort of workers formerly exposed to asbestos. SMRP, CA125, and CYFRA21-1 concentrations were determined in about 1,700 serum samples from 627 workers formerly exposed to asbestos. The impact of factors that could modify the concentrations of the tumor markers was examined with linear mixed models. SMRP values increased with age 1.02-fold (95% CI 1.01–1.03 and serum creatinine concentration 1.32-fold (95% CI 1.20–1.45. Levels differed by study centers and were higher after 40 years of asbestos exposure. CA125 levels increased with longer storage of the samples. CYFRA21-1 values correlated with age 1.02-fold (95% CI 1.01–1.02, serum creatinine 1.21-fold (95% CI 1.14–1.30 and varied by study centers due to differences in sample handling. Tumor marker concentrations are influenced by subject-related factors, sample handling, and storage. These factors need to be taken into account in screening routine.

    Previous screening trials for early detection of ovarian cancer in postmenopausal women have used the standard CA125 cut-point of 35 U/mL, the 98th percentile in this population yielding a 2% false positive rate, whereas the same cut-point in trials of premenopausal women results in substantially higher false positive rates. We investigated demographic and clinical factors predicting CA125 distributions, including 98th percentiles, in a large population of high-risk women participating in two ovarian cancer screening studies with common eligibility criteria and screening protocols. Baseline CA125 values and clinical and demographic data from 3,692 women participating in screening studies conducted by the National Cancer Institute-sponsored Cancer Genetics Network and Gynecologic Oncology Group were combined for this preplanned analysis. Because of the large effect of menopausal status on CA125 levels, statistical analyses were conducted separately in pre- and postmenopausal subjects to determine the impact of other baseline factors on predicted CA125 cut-points on the basis of 98th percentile. The primary clinical factor affecting CA125 cut-points was menopausal status, with premenopausal women having a significantly higher cut-point of 50 U/mL, while in postmenopausal subjects the standard cut-point of 35 U/mL was recapitulated. In premenopausal women, current oral contraceptive (OC) users had a cut-point of 40 U/mL. To achieve a 2% false positive rate in ovarian cancer screening trials and in high-risk women choosing to be screened, the cut-point for initial CA125 testing should be personalized primarily for menopausal status (50 for premenopausal women, 40 for premenopausal on OC, and 35 for postmenopausal women).

    Full Text Available In this case report, a ruptured ovarian endometrioma with a very high CA-125 level, moderately elevated CA 19-9, and CA 15-3 levels is presented. A 20 years old patient, complaining from pelvic pain, 5 cm adnexial mass was detected on left side. Biochemical examination was revealed very high CA-125 value (2556IU/ml, moderately elevated CA 19-9 (134IU/ml, and CA 15-3 (65IU/ml values. Laparoscopy was done and a ruptured ovarian endometrioma of 5 cm was seen during operation. After the total excision of the cyst, tumor markers fell rapidly. Very high CA-125 value, moderately elevated CA19-9, and CA 15-3 values can be seen in cases with ruptured endometrioma. In young patients, endometrioma must be considered firstly and laparoscopy should be applied instead of more invasive methods unless there was any finding or strong suspicion about malignancy.

    A 4-year-old girl was referred for evaluation for a mild but persistent serum aspartate aminotransferase (AST) elevation detected incidentally during routine blood screening for a skin infection. Serum creatine kinase activity was found to be increased. Immuno-histochemical study for dystrophin in her muscle biopsy showed results consistent with a carrier state for muscular dystrophy. Molecular work-up showed the proposita to be a carrier of a deletion mutation of exon 48 of the dystrophin gene. Four male relatives also had the deletion mutation, yet showed no clinical symptoms of muscular dystrophy (age range 8-58 yrs). Linkage analysis of the dystrophin gene in the family showed a spontaneous change of an STR45 allele, which could be due to either an intragenic double recombination event, or CA repeat length mutation leading to identical size alleles. To our knowledge, this is the first documentation of an asymptomatic dystrophinopathy in multiple males of advanced age. Based on molecular findings, this family would be given a diagnosis of Becker muscular dystrophy. This diagnosis implies the development of clinical symptoms, even though this family is clearly asymptomatic. This report underscores the caution which must be exercised when giving presymptomatic diagnoses based on molecular studies. 28 refs., 4 figs., 1 tab.

    Full Text Available OBJECTIVE: Differentiation between benign and malignant ovarian neoplasms is essential for creating a system for patient referrals. Therefore, the contributions of the tumor markers CA125 and human epididymis protein 4 (HE4 as well as the risk ovarian malignancy algorithm (ROMA and risk malignancy index (RMI values were considered individually and in combination to evaluate their utility for establishing this type of patient referral system. METHODS: Patients who had been diagnosed with ovarian masses through imaging analyses (n = 128 were assessed for their expression of the tumor markers CA125 and HE4. The ROMA and RMI values were also determined. The sensitivity and specificity of each parameter were calculated using receiver operating characteristic curves according to the area under the curve (AUC for each method. RESULTS: The sensitivities associated with the ability of CA125, HE4, ROMA, or RMI to distinguish between malignant versus benign ovarian masses were 70.4%, 79.6%, 74.1%, and 63%, respectively. Among carcinomas, the sensitivities of CA125, HE4, ROMA (pre-and post-menopausal, and RMI were 93.5%, 87.1%, 80%, 95.2%, and 87.1%, respectively. The most accurate numerical values were obtained with RMI, although the four parameters were shown to be statistically equivalent. CONCLUSION: There were no differences in accuracy between CA125, HE4, ROMA, and RMI for differentiating between types of ovarian masses. RMI had the lowest sensitivity but was the most numerically accurate method. HE4 demonstrated the best overall sensitivity for the evaluation of malignant ovarian tumors and the differential diagnosis of endometriosis. All of the parameters demonstrated increased sensitivity when tumors with low malignancy potential were considered low-risk, which may be used as an acceptable assessment method for referring patients to reference centers.

The medical records of 370 patients with endometrial endometrioid adenocarcinoma who underwent surgical staging in the Obstetrics & Gynecology Hospital of Fudan University were collected and retrospectively reviewed. Immunohistochemical markers were screened. A model using serum cancer antigen 125 (CA125 level, the immunohistochemical markers progesterone receptor (PR and Ki67 was created for prediction of LNM. A predicted probability of 4% among these patients was defined as low risk. The developed model was externally validated in 200 patients from Shanghai Cancer Center. The efficiency of the model was compared with three other reported prediction models. Patients with serum CA125 50% and Ki67 < 40% in cancer lesion were defined as low risk for LNM. The model showed good discrimination with an area under the receiver operating characteristic curve of 0.82. The model classified 61.9% (229/370 of patients as being at low risk for LNM. Among these 229 patients, 6 patients (2.6% had LNM and the negative predictive value was 97.4% (223/229. The sensitivity and specificity of the model were 84.6% and 67.4% respectively. In the validation cohort, the model classified 59.5% (119/200 of patients as low-risk, 3 out of these 119 patients (2.5% has LNM. Our model showed a predictive power similar to those of two previously reported prediction models. The prediction model using serum CA125 and the immunohistochemical markers PR and Ki67 is useful to predict patients with a low risk of LNM and has the potential to provide valuable guidance to clinicians in the treatment of patients with endometrioid endometrial cancer.

    Objective:Biomarkers associated with cancer screening (CA125, CA15‐3, CA72‐4, total prostate specific antigen [tPSA]) and the monitoring of pregnancy (pregnancy associated plasma protein‐A [PAPP‐A]) were measured during natural and stimulated ovarian cycles in disease‐free non-pregnant women to determine if they could reflect normal events relating to ovulation and/or endometrial changes. Methods: A total of 73 blood samples (10 women) collected throughout the natural menstrual cycle, and 64 blood samples (11 women) taken during stimulated ovarian cycles, were analysed on the Roche Cobas e411 automated analyser. Results:Detectable levels of tPSA were measured in at least one point in the cycle in 6/10 of women in the natural cycle and 10/11 of women in stimulated cycles, and CA72-4 was detected in only 12/21 women tested. Concentrations of CA125, tPSA, CA15‐3 and CA72‐4 showed no significant difference between the natural and stimulated ovarian cycle groups. On average the mean PAPP‐A of the natural group was (2.41±0.58) mIU/L higher than the stimulated group (t=4.10, P< 0.001). CA125 and CA15‐3 results were both significantly influenced by the stage of the cycle (P<0.0001), whereas tPSA and PAPP‐A concentrations revealed no significant changes (P≥0.65). CA72‐4 was not affected by the stage of the cycle nor ovarian stimulation. Conclusion:Ovarian stimulation reduced serum PAPP‐A levels, CA125 and CA15‐3 levels were generally unaffected by ovarian stimulation but displayed cyclical changes throughout both natural and stimulated cycles, whilst tPSA and CA72-4 were not affected by the stage of the cycle or ovarian stimulation.

    Objective: To identify the clinical significance of the changes of serum and dialysate C-reactive protein (CRP) and CA125 levels in the frequency peritoneal dialysis-related peritonitis. Method:Serum and dialysate CRP and CA125 levels of peritoneal dialysis-related peritonitis patients were detected in emission immunization and using the automatic biochemistry meter before or after anti-infection treatment.15 patients with two or more onsets in one year were induced into group A, the frequency peritoneal dialysis -related peritonitis group, and the other 44 patients were induced into group B, the pure peritonitis group,served as the control group. The clinical and laboratory data of the two groups were compared and analyzed.Result: Compared with those in the control group, after anti-infection treatment the patients in group A had significantly higher serum and dialysate CRP levels ( P<0. 05 ) than that in group B , but the similarly reduced dialysate CA125 levels. During the infection, dialysate CA125 levels in two groups were both increased, but non-statistics significance ( P>0.05 ). And at the the first time of anti-infection treatment, dialysate CA125 levels in group A were the same as group B( P>0. 05 ), but at the the last time were lower than that in group B( P<0. 05 ). Conclusion: Detecting the change of serum and dialysate CRP and CA125 levels in the frequency peritoneal dialysis-related peritonitis patients is instructive to estimate the prognosis of peritonitis and the function of peritoneum.%目的:探讨频发腹膜透析相关性腹膜炎患者血清及透出液C反应蛋白(CRP)和癌抗原125(CA125)浓度变化的临床意义.方法:采用放射免疫法及自动生化仪检测腹膜透析相关性腹膜炎患者抗感染治疗前后血清及透出液CRP和CA125浓度.1年内发生2次及以上腹膜炎的患者归入频发腹膜炎组(A组)共15例,其余44例归入单纯腹膜炎组(B组),对照分析两组间数据.结果:治疗后血

    Full Text Available Mucin 16 (MUC16 is a type I transmembrane protein, the extracellular portion of which is shed after proteolytic degradation and is denoted as CA125 antigen, a well known tumor marker for ovarian cancer. Regarding its polypeptide and glycan structures, as yet there is no detailed insight into their heterogeneity and ligand properties, which may greatly influence its function and biomarker potential. This study was aimed at obtaining further insight into the biological capacity of MUC16/CA125, using in silico analysis of corresponding mucin sequences, including similarity searches as well as GO (gene ontology-based function prediction. The results obtained pointed to the similarities within extracellular serine/threonine rich regions of MUC16 to sequences of proteins expressed in evolutionary distant taxa, all having in common an annotated role in adhesion-related processes. Specifically, a homology to conserved domains from the family of herpesvirus major outer envelope protein (BLLF1 was found. In addition, the possible involvement of MUC16/CA125 in carbohydrate-binding interactions or cellular transport of protein/ion was suggested.

    Preoperative levels of the trace elements copper and zinc, in addition to the level of the known marker CA 125, were studied in sera of 32 patients undergoing exploratory laparotomy for suspicion of ovarian cancer and in sera of 49 patients with the diagnosis of ovarian cancer prior to second-look operation. Most patients (63/81) had stage III or IV disease. CA 125 levels greater than 35 U/ml, copper levels greater than 1.5 mg/liter, and zinc levels less than 0.9 mg/liter were considered pathologic. An immunochemical panel composed of CA 125 serum level and ratio of copper to zinc (Cu/Zn) (normal less than 1.65) was found to be most sensitive (98%) in predicting the existence of ovarian cancer before laparotomy, and its overall predictability was 89%. In 14 of 14 patients (100%) who had complete primary surgery for ovarian cancer, the panel was correct in predicting no tumor at second-look operation. In 13 of 14 patients (93%) who had incomplete primary surgery but had no clinical evidence of disease prior to second-look operation, the panel was correct in predicting ovarian cancer. In these two groups of patients, second-look operation could have been replaced by the results of the immunochemical panel.

    Metastatic breast carcinoma to the ovary is sometimes difficult to differentiate from primary ovarian carcinoma. This problem is often encountered in breast carcinoma patients who develop adnexal masses. ER and PR can be positive in a high percentage of breast and ovarian carcinomas, and therefore cannot be used in the differential diagnosis of these entities. WT1 and CA125 have been identified as possible markers for ovarian cancer. However, no studies have been done that specifically compare the immunophenotype of breast carcinoma metastatic to ovary with that of primary ovarian cancer. Thirty-nine cases of metastatic breast carcinoma to the ovary, 36 primary breast carcinomas, and 42 primary ovarian carcinomas were examined immunohistochemically for the expression of WT1, CA125, carcinoembryonic antigen, MUC2, MUC1, and GCDFP. The percentage of cells stained and the intensity of staining were recorded. Thirty-two ovarian carcinomas (76%) were positive for WT1, including 31 of 33 (94%) serous carcinomas. Most of them had strong and diffuse staining. None of the breast cancers either primary or metastatic to the ovary expressed WT1. Thirty-eight (90%) ovarian carcinomas were positive for CA125, most of them with strong and diffuse staining. Most breast carcinomas were negative for CA125, with only 6 (16%) of the primary ones and 5 (12%) of the metastatic showing weak and focal positivity. All ovarian carcinomas were negative for GCDFP. Five primary breast cancers (14%) and 17 (43%) metastatic to the ovary were positive for GCDFP. Nine (21%) ovarian carcinomas, 8 (22%) primary breast carcinomas, and 13 (33%) metastatic to the ovary were positive for carcinoembryonic antigen. Almost all tumors examined were positive for MUC1 (100% ovarian carcinomas, 100% primary breast carcinomas, and 95% metastatic breast carcinomas to ovary). MUC2 was positive in 10 (24%) ovarian carcinomas, 3 (8%) primary breast cancers, and 12 (30%) metastases to the ovary. The presence of

    Point-of-care (POC) implementation of early detection and screening methodologies for ovarian cancer may enable improved survival rates through early intervention. Current laboratory-confined immunoanalyzers have long turnaround times and are often incompatible with multiplexing and POC implementation. Rapid, sensitive, and multiplexable POC diagnostic platforms compatible with promising early detection approaches for ovarian cancer are needed. To this end, we report the adaptation of the programmable bio-nano-chip (p-BNC), an integrated, microfluidic, and modular (programmable) platform for CA125 serum quantitation, a biomarker prominently implicated in multimodal and multimarker screening approaches. In the p-BNCs, CA125 from diseased sera (Bio) is sequestered and assessed with a fluorescence-based sandwich immunoassay, completed in the nano-nets (Nano) of sensitized agarose microbeads localized in individually addressable wells (Chip), housed in a microfluidic module, capable of integrating multiple sample, reagent and biowaste processing, and handling steps. Antibody pairs that bind to distinct epitopes on CA125 were screened. To permit efficient biomarker sequestration in a three-dimensional microfluidic environment, the p-BNC operating variables (incubation times, flow rates, and reagent concentrations) were tuned to deliver optimal analytical performance under 45 minutes. With short analysis times, competitive analytical performance (inter- and intra-assay precision of 1.2% and 1.9% and limit of detection of 1.0 U/mL) was achieved on this minisensor ensemble. Furthermore, validation with sera of patients with ovarian cancer (n = 20) showed excellent correlation (R(2) = 0.97) with gold-standard ELISA. Building on the integration capabilities of novel microfluidic systems programmed for ovarian cancer, the rapid, precise, and sensitive miniaturized p-BNC system shows strong promise for ovarian cancer diagnostics.

    Full Text Available Information on menstrual cycle dependent variation of tumor markers in healthy women is a subject of diagnostic efficiency and has an impact in elucidating the normal function of these markers. In this study midfollicular and midluteal concentrations of serum CEA, AFP, CA 19-9, CA 125, CA 15-3 and their relations with LH, FSH, prolactin, estradiol and progesterone were evaluated during ovulatory cycles in a group of 23 healthy female individuals. Samples were collected on the 7th and 21st day of the same menstrual cycle. Tumor marker and hormone concentrations were determined with chemiluminescence or electrochemiluminescence EIA methods. A significant phase-dependent difference was observed for CA 15-3, midluteal concentrations (mean ± SEM; 26.33 ± 1.56 U/ml higher than the midfollicular (mean ± SEM; 19.27 ± 1.49 U/ml concentrations (p < 0.001. But an obvious difference for other tumor markers investigated did not exist. Significant correlations of follicular and luteal CA 125 levels with body mass index of the subjects were observed (r:0.52, p < 0.05 and r:0.57, p < 0.005, respectively.

    Pelvic and peritoneal tuberculosis may resemble advanced ovarian cancer due to the presence of ascites, complex adnexal masses, peritoneal deposits and raised CA-125 level, especially in peri- and postmenopausal women. Other common features among women with these two conditions are abdominal pain and distension, weight loss and reduced appetite. As the treatment of pelvic-peritoneal tuberculosis is completely different from that of ovarian cancer, it is important to reach a correct diagnosis. Sometimes women with pelvic-peritoneal tuberculosis may be subjected to a laparotomy for suspected ovarian cancer which is likely to increase their morbidity. In the present article, we report ten women in the peri- and post-menopausal age group where this diagnostic dilemma arose of whom seven were diagnosed only after a laparotomy had been performed for suspected ovarian cancer due to adnexal masses with ascites and raised CA-125 level. Ascitic fluid showing lymphocytic predominance, raised ADA level and absence of malignant cells are pointers to consider the possibility of pelvic- peritoneal tuberculosis, especially in endemic countries like India. In such situations, an effort should be made to obtain a cytological or histopathological diagnosis of either condition by ultrasound guided needle biopsy or laparoscopically obtained biopsy rather that proceeding with laparotomy for suspected ovarian cancer.

    A multiplexed MNPs-Abs based fluorescence spectroscopic system in analysis of serum biomarkers; CA-125, β2-M and ApoA1 for the early detection of ovarian cancer was first time proposed. The lowest detection limits measured in multiplexed setup were 0.26 U/mL, 0.55 ng/mL and 7.7 ng/mL respectively for CA-125, β2-M and ApoA1. A comparative real sample analysis of healthy normal (Control), benign and ovarian cancer patients with SPR has also been done to validate the process. Moreover CA-125 detection only confirms 50-60% of early stage disease. This multiplexed system achieved sensitivity and specificity up to 94% and 98% respectively to distinguish early stage ovarian cancer patients from healthy individuals.

    The natural history of asymptomatic seroconversion to Borrelia burgdorferi has been unclear. We report here, on the basis of a post hoc assessment, the frequency and outcome of asymptomatic seroconversion to B. burgdorferi in participants of a large Lyme disease vaccine trial. We show that infection with B. burgdorferi may be asymptomatic but that asymptomatic infection is unusual in the United States.

    2001-10-01

    Little is known about the natural history of asymptomatic Borrelia burgdorferi infection. Our analysis of the asymptomatic infections diagnosed serologically in a recent OspA vaccine trial conducted in the United States (N Engl J Med 1998;339: 209-215), suggests that the natural history of this event is more benign than that reported for untreated patients with erythema migrans (Ann Intern Med 1987;107: 725-731). We hypothesize that this is due either to incorrect diagnosis since the specificity of the serologic criteria used to diagnose asymptomatic infection in the vaccine study is unknown, or to infection with non-pathogenic strains of B. burgdorferi. Increasing evidence indicates that the invasive potential of strains of B. burgdorferi varies according to the specific subtype. Theoretically, a serologic testing method could be devised which would distinguish infection with invasive versus non-invasive strains of B. burgdorferi, and allow testing of the second hypothesis.

    肝硬化时肿瘤标记物的升高往往是非特异性的,目前尚无将其应用于鉴别肝纤维化程度的相关报道。该文旨在探讨肿瘤标记物是否能用于预测重度肝纤维化。研究选取125例接受过肝活检的酒精性肝炎、乙型肝炎或丙型肝炎患者,采用常规的实验室方法检测其肿瘤标记物CA19—9、CA15—3、CA125水平,并分析其与肝纤维化程度之间的相关性。其中,肝纤维化1~2级被定义为轻度纤维化,而3~4级则定义为重度纤维化。研究表明,肿瘤标记物CA19—9、CA15—3、CA125的水平随肝纤维化的程度而升高。应用于鉴别轻度(F1+F2)或重度肝纤维化(F3+F4)时,CA19—9、CA125、CA15—3的敏感度与特异度分别为70.5%、38.1%、19.0%与88.6%、89.7%、93.0%。CA19—9和CA125联合评分的logistic回归分析表明,CA19—9/CA125评分每升高1分,重度肝纤维化的可能性就增加1。6倍。与目前广泛应用的肝硬化Bonacini判断评分相比,CA19—9/CA125评分有相似特异度(97.1%vs100%),而敏感度更高(42.9%vs33.3%)。CA19—9与CA125的协同升高由:于二检测相对简便,因此除了可获得相似的特异度(98.5%)之外,亦能达到最佳的阳性预测值(92.9%),

    The aim of the study is to examine the cancer-predictive values of SMRP (soluble mesothelin-related peptides), CA125, and CYFRA21-1 as potential tumor markers for lung cancer and malignant mesothelioma in a cohort of workers formerly exposed to asbestos. A voluntary surveillance program has been established for German workers with former asbestos exposure. A subgroup of 626 subjects with a mean age of 63 years (range 53-70 years) at baseline was enrolled in an extended health examination program with high-resolution computer tomography (HRCT) of the chest and blood drawing between 1993 and 1997. Serum concentrations of SMRP, CA125, and CYFRA21-1 were measured in archived serum samples in 2005 and 2006. A mortality follow-up was conducted through 2007. So far, 12 cases with lung cancer and 20 cases with malignant mesothelioma have been observed in this cohort. The average time between sample collection and diagnosis was 4.7 years. Analyzed biomarkers showed low sensitivities (5-25%) and positive predictive values (4-30%) for both cancer sites. Marker combinations resulted in sensitivities between 5 and 50% and positive predictive values ranging from 3 to 14%. Even in those cases, where biomarker concentrations were available within 36 months before diagnosis, no trend for increasing biomarker levels was observed. The analyzed tumor markers were characterized by high specificities, but low sensitivities. SMRP, CA125, and CYFRA21-1 alone or in combination were less suitable to serve as predictors for the diagnosis of lung cancer or malignant mesothelioma. However, a prospective study with annual sampling might reveal a better predictive value of these markers. (orig.)

    Objective To analyze the progression of asymptomatic osteonecrosis of the femoral head by evaluating its lesion size and location.Methods From January 2008 to June 2009, 24 cases or hips were available for outcome analysis.There were 16 males and 8 females with a mean age of 36.4 (22-46) years and a mean body mass index of 25.4 ( 17.5-35 ).The stages were Ⅰa ( n=2 ) , b ( n=4 ) , Ⅱa (n=6), Ⅱb (n =8) and Ⅱc (n =4) according to ARCO staging system.The etiologies included corticosteroids ( n=16 ) , alcohol abuse ( n =4 ) and idiopathic disease ( n =4 ).Magnetic resonance imaging ( MRI) was used to measure lesion sizes with necrotic index method.And lesion locations were classified as medial , central and lateral.Results The mean follow-up period was 40.3 (32-60) months.Among 7 painful hips, there were corticosteroids (n=5) and alcohol abuse (n=2).And 5 hips (20.8%) collapsed.The mean interval between diagnosis and symptom was 40 (36-48) months.The lesion locations were lateral-central ( n =4 ) lateral-central-medial ( n =3 ).Significant difference existed between the average necrotic index of symptomatic and asymptomatic hips (45.4%vs 32.7%).Conclusion There is a high risk of progression into symptomatic disease when the necrotic lesion occurs on the lateral and lateral -central or lateral-central-medial zone of the femoral head.Asymptomatic small and medially located lesions may be managed conservatively with close medical imaging observations.%目的:分析非症状性骨坏死未经手术治疗的早期病情转归及病灶大小、位置与病情进展的关系。方法自2008年1月至2009年6月,大连大学附属中山医院骨科收治的股骨头坏死患者病例中选取24例髋纳入本研究,男16例,女8例,年龄平均36.4(22~46)岁,体质指数平均25.4(17.5~35.0)。按照ARCO分期标准分为,Ⅰa期2髋,Ⅰb期4髋,Ⅱa期6髋,Ⅱb期8髋,Ⅱc期4髋。病因为激素性16例,酒精性4例,特发性4

  14. Immunohistochemical distinction of renal cell carcinoma from other carcinomas with clear-cell histomorphology: utility of CD10 and CA-125 in addition to PAX-2, PAX-8, RCCma, and adipophilin.

    Clear-cell renal cell carcinoma (CC-RCC) is the most common primary kidney malignancy, yet this morphology is not unique to renal primary tumors, as clear-cell variants of numerous nonrenal carcinomas of varying lineages exist. Therefore, because of CC-RCC's ability to metastasize to nearly any anatomic location, ancillary studies such as immunohistochemistry are often needed to establish the diagnosis. Despite CD10 and renal cell carcinoma monoclonal antibody (RCCma) being touted as sensitive and specific markers, some have suggested that more recent stains including PAX-2, PAX-8, or adipophilin (ADP) are more robust markers of CC-RCC. In this study, 26 cases of CC-RCC, and 51 nonrenal carcinomas with clear-cell histomorphology (CCM) were stained with CD10, RCCma, PAX-2, PAX-8, and ADP. CA-125 was also included to help distinguish CC-RCC from Müllerian clear-cell carcinomas, due the known expression of PAX-2 and PAX-8 in both these entities. RCCma highlighted 77% of CC-RCC and 27% of the CCM group, whereas CD10 was positive in 85% and 25%, respectively. ADP highlighted all CC-RCC and 45% of CCMs. PAX-2 was positive in 81% of CC-RCC and 24% of CCM, whereas PAX-8 stained 100% of CC-RCC and 39% of CCM. Müllerian-derived tumors (clear-cell carcinomas of the ovary, vagina, and cervix) were positive with PAX-2 and PAX-8 in 69% and 100% of cases, respectively. No cases of CC-RCC stained with CA-125, whereas 88% of the Müllerian-derived tumors were positive. In summary, although new markers such as PAX-2 and PAX-8 tend to be more sensitive markers of CC-RCC, they lose specificity when Müllerian tumors are included. Inclusion of a classic renal marker such as CD10 or RCCma in the immunohistochemical panel, as well as CA-125 obviates this difficulty.

    Mesonephric adenocarcinomas are rare neoplasms that most commonly arise in the uterine cervix and exceptionally rarely in the uterine corpus. Although the morphologic features of these neoplasms are well described, there has been relatively limited investigation of the immunoprofile. We report a series of 8 mesonephric adenocarcinomas arising in the uterine cervix (7 cases) and corpus (1 case) and undertake a comprehensive immunohistochemical analysis. This includes markers that have not been investigated previously in mesonephric adenocarcinomas but that are commonly used in gynecologic pathology and may be undertaken when other, mainly Mullerian, adenocarcinomas are considered in the differential diagnosis. Linear array human papillomavirus (HPV) genotyping was also performed. Our results broadly confirm the immunohistochemical profile demonstrated in previous studies with the majority of mesonephric adenocarcinomas staining positively with CD10 (6 of 8), epithelial membrane antigen (8 of 8), vimentin (8 of 8), and calretinin (7 of 8). Estrogen receptor was positive in 2, carcinoembryonic antigen in 3, and inhibin in 4 cases. p16 was positive in 5 cases (1 diffuse and strong), despite all being HPV negative (in 1 case, there was insufficient DNA for HPV analysis). Novel findings in our study were the demonstration of nuclear positivity with PAX8 and HMGA2 in 7 cases, CA125 immunoreactivity in all 8 cases, and TTF1 and hepatocyte nuclear factor 1-β staining in 3 cases. As PAX8, CA125, HMGA2, and hepatocyte nuclear factor 1-β are commonly positive in a variety of Mullerian adenocarcinomas arising in the female genital tract, this may result in diagnostic confusion. All cases were WT1 negative.

    2006-01-01

    ViRexx Medical Corp is developing the murine monoclonal antibody oregovomab [OvaRex, MAb B43.13] for the treatment of ovarian cancer. Oregovomab targets the circulating tumour-associated antigen CA 125, which is shed from the surface of human ovarian cancer cells; the antibodies induce broad cellular and humoral immune responses against CA 125 via complex formation. Unlike free CA 125, CA 125-oregovomab complexes can prime dendritic cells, leading to downstream activation of T cells. The antibody is undergoing advanced clinical development. AltaRex, the originator of oregovomab, was acquired by, and merged into, ViRexx Medical Corp in December 2004. AltaRex (now ViRexx Medical Corp) has established several strategic corporate alliances for the development and/or commercialisation of oregovomab. Unither Pharmaceuticals, a subsidiary of United Therapeutics Corporation, entered into a licensing agreement with ViRexx in April 2002. The agreement covers most territories worldwide, except Europe and the Middle East, which are covered by other agreements (see below); ViRexx did retain the rights to most member nations of the EU and certain other countries. In August 2003, the agreement was extended, granting United Therapeutics Corporation development rights for Germany. AltaRex and Dompe entered into a distribution agreement for oregovomab in July 2004. Territories included in the agreement are Italy, Spain, Portugal, Hungary, Poland, Czech Republic, Switzerland, Austria and certain other Eastern European countries. Under the terms of the agreement, ViRexx retains responsibility for product development and registration of the antibody, upon commercialisation in the agreed territory. The two companies will work closely to achieve product registration throughout Europe. In June 2001, Dompe entered into a sublicensing agreement with FAES for the commercialisation of oregovomab in Spain and Portugal. ViRexx is also seeking collaboration partners for Northern European markets

    Ovarian cancer is a lethal gynecologic malignancy with greater than 70% of women presenting with advanced stage disease. Despite new treatments, long term outcomes have not significantly changed in the past 30 years with the five-year overall survival remaining between 20% and 40% for stage Ⅲ and Ⅳ disease. In contrast patients with stage Ⅰ disease have a greater than 90% five-year overall survival. Detection of ovarian cancer at an early stage would likely have significant impact on mortality rate. Screening biomarkers discovered at the bench have not translated to success in clinical trials. Existing screening modalities have not demonstrated survival benefit in completed prospective trials. Advances in high throughput screening are making it possible to evaluate the development of ovarian cancer in ways never before imagined. Data in the form of human "-omes" including the proteome, genome, metabolome, and transcriptome are now available in various packaged forms. With the correct pooling of resources including prospective collection of patient specimens, integration of high throughput screening, and use of molecular heterogeneity in biomarker discovery, we are poised to make progress in ovarian cancer screening. This review will summarize current biomarkers, imaging, and multimodality screening strategies in the context of emerging technologies.

    2010-06-01

    Full Text Available Background: Asymptomatic bacteriuria is the significant presence of bacteria in the urine of an individual without symptoms. In pregnancy, the apparent reduction in immunity of pregnant women tends to encourage the growth of pathogens. Aim: This study was carried out to determine the prevalence of asymptomatic bacteriuria in pregnant women attending a primary health centre in Benin City, Nigeria. Materials and Methods: A total of 1,228 pregnant women were recruited for this study. All subjects were clinically identified to have no signs and symptoms of UTI. Clean catch midstream urine sample was collected from each patient into sterile universal container. The urine samples were examined microscopically and by cultural method. Identification of isolates was by standard microbiological technique. Result: A total of 556 (45.3% were positive for significant bacteriuria. There was a significant difference in the prevalence of asymptomatic bacteriuria with respect to age (P < 0.0001. Trimester did not show any significant difference (P = 0.2006 in the prevalence of asymptomatic bacteriuria. Escherichia coli was the most predominant organism followed closely by Staphylococcus aureus. Ciprofloxacin, Ceftriaxone and Augmentin were found to be the most effective antibiotics against the urinary isolates. Conclusion: Asymptomatic bacteriuria is not uncommon among antenatal patients in the population studied. Routine urine cultural test should be carried out on all antenatal patients in order to identify any unsuspecting infection. This measure will go a long way in reducing maternal and obstetric complications associated with pregnancy.

    2016-01-01

    Aortic stenosis(AS) is a disease that progresses slowly for years without symptoms, so patients need to be carefully managed with appropriate follow up and referred for aortic valve replacement in a timely manner. Development of symptoms is a clear indication for aortic valve intervention in patients with severe AS. The decision for early surgery in patients with asymptomatic severe AS is more complex. In this review, we discuss how to identify high-risk patients with asymptomatic severe AS who may benefit from early surgery.

    Full Text Available Background: Urinary tract infections (UTIs are the most common bacterial infections during pregnancy. Asymptomatic bacteriuria (ASB is a major risk factor for the development of urinary tract infections during pregnancy and with further risk of preterm birth & pyelonephritis if untreated. Aims & Objectives: This study was carried out to determine the prevalence of asymptomatic bacteriuria (ASB in pregnant women & to isolate, identify and establish antimicrobial susceptibility of pathogens. Methods: A total of 500 pregnant women were studied over a period of one year. Clean catch midstream urine sample was collected into a sterile container & then subjected to culture method. Results: Significant bacteriuria was noted in 45 patients (9%. 3% patients had insignificant bacteriuria. Growth of contaminants was noted in 8%. 80% samples were sterile with no growth. E. coli was the most common etiological agent, followed by Staphylococcus aureus. Conclusions: Asymptomatic bacteriuria is not uncommon in antenatal patients. All pregnant women should be screened by urine culture to detect asymptomatic bacteriuria at their first visit to prevent overt UTI & other complications in both mother & fetus.

    Full Text Available Asymptomatic bacteriuria and urinary tract infection are common complications after kidney transplantation. In this population, if urinary tract infection occurred in the first six months post procedure, it carries a grave impact on both graft and patient survival. Renal transplant recipients with urinary tract infection are often clinically asymptomatic as a consequence of immunosuppression. Urinary tract infection, however, may progress to acute pyelonephritis, bacteremia and the full blown picture of urosepsis. PubMed and Cochrane databases were searched. The purpose of this review is to discuss the screening and treatment of urinary tract infection and asymptomatic bacteriuria in renal transplant recipients and to evaluate the guidelines on the basis of a review of published evidence.

    Asymptomatic bacteriuria is one of the most common and important bacterial infections during pregnancy and can result in progressive infections and endanger maternal as well as fetal health. In this study, we assessed the relationship between asymptomatic bacteriuria and pre-eclampsia. In this case-control study, pregnant women who presented to Imam Reza Hospital in Kermanshah in 2013-14 were studied. The minimum sample size was calculated as 125 pregnant women in each group with a total of 250 subjects. There were 125 women with pre-eclampsia and 125 women without pre-eclampsia (control group). Matching was done for age, gestational age, and parity between case and control groups. Matching was verified by a P value of 0.061 for maternal age and gestational age and 0.77 for parity. The statistical analyses were done by applying the chi-squared test and determining odds ratio (OR) for having bacteriuria in univariate logistic regression as well as multivariate regression with adjusting the effect of maternal age, gestational age, and parity. Pyuria and bacteriuria were significantly more common in pre-eclampsia group than in control group. The results showed that a significant association existed between asymptomatic bacteriuria and pre-eclampsia. The rate of asymptomatic bacteriuria was 6.8 times higher in women with pre-eclampsia compared to those without pre-eclampsia. Further studies are required for better clarification of association between asymptomatic bacteriuria and pre-eclampsia.

    Full Text Available In this article, we present the case of a 52-year-old male with a history of parotid carcinosarcoma with initial diagnosis being 18 months prior. Initial treatment included a combination of gamma knife surgery coupled with high dosage chemotherapy and X-ray radiation therapy. At the time of follow-up, the patient presented with no complaints and had a nearly normal physical exam with the exception of some facial nerve weakness on the same side as the initial surgery. Despite being asymptomatic, the patient had a significant progression of disease that was manifested with intracranial lesions, multiple pathologic fractures, and a dramatic increase in overall tumor burden. Ultimately, the patient decided to pursue comfort measures only and succumbed to the disease peacefully soon thereafter.

    Asymptomatic leishmaniasis may drive the epidemic and an important challenge to reach the goal of joint Visceral Leishmaniasis (VL) elimination initiative taken by three Asian countries. The role of these asymptomatic carriers in disease transmission, prognosis at individual level and rate of transformation to symptomatic VL/Post Kala-azar Dermal Leishmaniasis (PKDL) needs to be evaluated. Asymptomatic cases were diagnosed by active mass survey in eight tribal villages by detecting antileishmanial antibody using rK39 based rapid diagnostic kits and followed up for three years to observe the pattern of sero-conversion and disease transformation. Out of 2890 total population, 2603 were screened. Antileishmanial antibody was detected in 185 individuals of them 96 had a history of VL/PKDL and 89 without such history. Seventy nine such individuals were classified as asymptomatic leishmaniasis and ten as active VL with a ratio of 7.9:1. Out of 79 asymptomatic cases 2 were lost to follow up as they moved to other places. Amongst asymptomatically infected persons, disease transformation in 8/77 (10.39%) and sero-conversion in 62/77 (80.52%) cases were noted. Seven (9.09%) remained sero-positive even after three years. Progression to clinical disease among asymptomatic individuals was taking place at any time up to three years after the baseline survey. If there are no VL /PKDL cases for two or more years, it does not mean that the area is free from leishmaniasis as symptomatic VL or PKDL may appear even after three years, if there are such asymptomatic cases. So, asymptomatic infected individuals need much attention for VL elimination programme that has been initiated by three adjoining endemic countries. PMID:28187202

    Full Text Available "nPregnant women are at increased risk for urinary tract infection (UTI but in many cases infection is asymptomatic. This study was performed to determine the incidence of asymptomatic bacteriuria and pyuria in pregnant women. A total of 86 pregnant women during first trimester and 56 nonpregnant women were evaluated. All subjects were clinically identified to have no signs and symptoms of UTI. Clean catch midstream urine samples were collected for both groups. Urine samples were examined microscopically and were cultured. Bacteriological examination revealed asymptomatic bacteriuria in 25 (29.1% and 3 (5.4% of the study group and controls, respectively (P < 0.05. Microscopic analysis of urine revealed pyuria in 18 (20.9% and 3 (5.4% of the study group and controls, respectively (P < 0.05. In study group, Escherichia coli were found in 20%, Staphylococcus epidermidis in 36%, Staphylococcus haemolyticus in 12%, streptococcus group D in 12%, Staphylococcus saprophyticus in 12% and Proteus mirabilis in 8%. In control group, E. coli were found in 33.3% and S. epidermidis in 66.7%. Our results show that the incidence of asymptomatic bacteriuria is significantly higher in pregnant women than nonpregnant women. The main finding in the present study was that 29.1% of the pregnant women who were in first trimester had asymptomatic bacteriuria which is much higher than figures reported from other countries. The use of microscopic urinanalysis was not an effective method of detecting asymptomatic bacteriuria and urine culture is necessary for screening these pregnant women.

  13. Asymptomatic Esophageal Varices Should Be Endoscopically Treated

    Directory of Open Access Journals (Sweden)

    1998-01-01

    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.

    2016-09-01

    Transthyretin familial amyloid polyneuropathy (TTR-FAP) is a rare, severe, and irreversible, adult-onset, hereditary disorder caused by autosomal-dominant mutations in the TTR gene that increase the intrinsic propensity of transthyretin protein to misfold and deposit systemically as insoluble amyloid fibrils in nerve tissues, the heart, and other organs. TTR-FAP is characterized by relentless, progressively debilitating polyneuropathy, and leads to death, on average, within 10 years of symptom onset without treatment. With increased availability of disease-modifying treatment options for a wider spectrum of patients with TTR-FAP, timely detection of the disease may offer substantial clinical benefits. This review discusses mutation-specific predictive genetic testing in first-degree relatives of index patients diagnosed with TTR-FAP and the structured clinical follow-up of asymptomatic gene carriers for prompt diagnosis and early therapeutic intervention before accumulation of substantial damage.

    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.

    Asymptomatic hepatitis E virus (HEV) infections have been found in blood donors from various European countries, but the natural course is rarely specified. Here, we compared the progression of HEV viraemia, serostatus and liver-specific enzymes in 10 blood donors with clinically asymptomatic genotype 3 HEV infection, measuring HEV RNA concentrations, plasma concentrations of alanine/aspartate aminotransferase, glutamate dehydrogenase and bilirubin and anti-HEV IgA, IgM and IgG antibodies. RNA concentrations ranged from 77.2 to 2.19×105 IU/mL, with viraemia lasting from less than 10 to 52 days. Donors showed a typical progression of a recent HEV infection but differed in the first detection of anti-HEV IgA, IgM and IgG and seropositivity of the antibody classes. The diagnostic window between HEV RNA detection and first occurrence of anti-HEV antibodies ranged from eight to 48 days, depending on the serological assay used. The progression of laboratory parameters of asymptomatic HEV infection was largely comparable to the progression of symptomatic HEV infection, but only four of 10 donors showed elevated liver-specific parameters. Our results help elucidate the risk of transfusion-associated HEV infection and provide a basis for development of screening strategies. The diagnostic window illustrates that infectious blood donors can be efficiently identified only by RNA screening. PMID:27608433

    This study investigated sensory and motor nerve excitability properties to elucidate the development of diabetic neuropathy. A total of 109 type 2 diabetes patients were recruited, and 106 were analyzed. According to neuropathy severity, patients were categorized into G0, G1, and G2+3 groups using the total neuropathy score-reduced (TNSr). Patients in the G0 group were asymptomatic and had a TNSr score of 0. Sensory and motor nerve excitability data from diabetic patients were compared with data from 33 healthy controls. Clinical assessment, nerve conduction studies, and sensory and motor nerve excitability testing data were analyzed to determine axonal dysfunction in diabetic neuropathy. In the G0 group, sensory excitability testing revealed increased stimulus for the 50% sensory nerve action potential (P<0.05), shortened strength-duration time constant (P<0.01), increased superexcitability (P<0.01), decreased subexcitability (P<0.05), decreased accommodation to depolarizing current (P<0.01), and a trend of decreased accommodation to hyperpolarizing current in threshold electrotonus. All the changes progressed into G1 (TNSr 1–8) and G2+3 (TNSr 9–24) groups. In contrast, motor excitability only had significantly increased stimulus for the 50% compound motor nerve action potential (P<0.01) in the G0 group. This study revealed that the development of axonal dysfunction in sensory axons occurred prior to and in a different fashion from motor axons. Additionally, sensory nerve excitability tests can detect axonal dysfunction even in asymptomatic patients. These insights further our understanding of diabetic neuropathy and enable the early detection of sensory axonal abnormalities, which may provide a basis for neuroprotective therapeutic approaches.

    Asymptomatic spontaneous pneumothorax (ASPT) is an uncommon condition. Between January 1, 1989 and December 31, 1997, 269 patients were admitted to our department with spontaneous pneumothorax. Of the 269 patients, 5 had no symptoms at the time of discovery. Their ages ranged from 15 to 61 years (mean, 37.8 years), and all of them were male. Of the 5 patients with no complaints, 2 had bilateral metachronous pneumothoraces and 3 had hemilateral pneumothorax. All of these ASPTs were revealed by chest roentgenographs taken during medical examinations or follow-up studies relating to other diseases. The mean value of body mass index (BMI) was 19.96 +/- 1.4 (range 18.7 - 22.1). Two of the 5 patients underwent bilateral partial lung resection. Histopathological examination of the resected specimens showed elastofibrosis, scar formation, and an interruption of the elastic fiber of the pleura. In these 5 cases, clinical courses were uneventful, and relapse of the pneumothorax did not occur. Clinical physicians should be aware of the possibility of asymptomatic pneumothorax, as well as the optimal radiographic techniques for revealing small pneumothoraces.

    2017-01-01

    Asymptomatic spontaneous nephrocutaneous fistula is a rare and severe complication of chronic urolithiasis. We report a case of 56-year-old woman with a nephrocutaneous fistula (NFC) which developed from a superinfected urinoma following calyceal rupture due to an obstructing calculus in the left ureter. The patient was clinically asymptomatic and came to the emergency department for a painless left flank fluctuating mass. This urinoma was superinfected, with a delayed development of renal abscesses and perirenal phlegmon found on contrast-enhanced uro-computed tomography (CT), responsible for left renal vein thrombophlebitis and left psoas abscess. Thereafter, a 99 mTc dimercaptosuccinic acid (DMSA) scintigraphy revealed a nonfunctional left kidney, leading to the decision of left nephrectomy. Chronic urolithiasis complications are rare and only few cases are reported in medical literature. A systematic medical approach helped selecting the best imaging modality to help diagnosis and treatment. Indeed, uro-CT scan and renal scintigraphy with 99 mTc-DMSA are the most sensitive imaging modalities to investigate morphological and functional urinary tract consequences of NFC, secondary to chronic urolithiasis.

    Human brucellosis is mainly caused by contact with Brucella-infected animals and their secretions and carcasses. Individuals who are continuously in contact with animals are considered to be at a high risk but only some show symptoms and are diagnosed as cases of brucellosis. Here, we showed that asymptomatic brucellosis infections occur among humans. Asymptomatic infections mainly result from less frequent contact with Brucella and/or contact with low-virulence Brucella. In our study, patients with asymptomatic infection had low antibody titres and different contact patterns. Awareness of asymptomatic infection is important for early diagnosis of brucellosis and prevention of chronic infection.

    Full Text Available Intracranial lipomas are rarely observed, and accepted as the congenital lesion of central nervous system. Intracranial lipomas are usually based centrally and have benign character. In the brain, it is mostly localized in pericallosal region, quadrigeminal system, and suprasellar region and cerebellopontine angles. As being mostly asymptomatic, the patients occasionally constitute clinical symptoms according to localization area. These symptoms are systemic symptoms such as cephalalgia, drowsiness, crisis and ataxy. In this article, we aimed to present the intracranial lipomas phenomenon which was diagnosed to have caused ptosis and upper lateral sight problem, namely causing localized neurological symptom, situated in mesencephalon and having pressure effect, regarding a 57-year old male patient brought to the emergency service with the nausea, throwing up and cephalalgia ailments.

    Danon disease is a rare, codominant X-linked genetic disorder characterized by the triad of left ventricular hypertrophy, mental retardation, and peripheral myopathy. This disease is caused by mutations in the gene that encodes lysosomal associated membrane protein 2 (LAMP2), a deficiency of which results in the accumulation of autophagic granular débris within the vacuoles of muscle cells. This is a report of an asymptomatic 19-year-old man with Danon disease in the absence of mental retardation or clinically significant skeletal myopathy. This case underscores the importance of accurate diagnosis of unexplained left ventricular hypertrophy, in order to establish an appropriate treatment plan and to advise genetic counseling.

    Three-quarters of the estimated 390 million dengue virus (DENV) infections each year are clinically inapparent. People with inapparent dengue virus infections are generally considered dead-end hosts for transmission because they do not reach sufficiently high viremia levels to infect mosquitoes. Here, we show that, despite their lower average level of viremia, asymptomatic people can be infectious to mosquitoes. Moreover, at a given level of viremia, DENV-infected people with no detectable symptoms or before the onset of symptoms are significantly more infectious to mosquitoes than people with symptomatic infections. Because DENV viremic people without clinical symptoms may be exposed to more mosquitoes through their undisrupted daily routines than sick people and represent the bulk of DENV infections, our data indicate that they have the potential to contribute significantly more to virus transmission to mosquitoes than previously recognized.

    2016-06-26

    A 78-year-old asymptomatic woman was referred to our clinic for a second opinion regarding indication for mitral valve surgery. An echocardiogram showed a moderate mitral stenosis with a concomitant severe regurgitation. The most striking feature, however, was a giant left atrium with a parasternal anteroposterior diameter of 79 mm and a left atrial volume index of 364 mL/m². There are various echocardiographic definitions of a giant left atrium, which are mainly based on measurements of the anteroposterior diameter of the left atrium using M-mode in the parasternal long axis view. Since the commonly accepted method for echocardiographic evaluation of left atrial size is left atrial volume index, we propose a cut-off value of 140 mL/m(2) for the definition of a "giant left atrium".

    Adenoid hypertrophy is the most common cause of pediatric upper airway obstruction, and it can lead to cardiopulmonary complications such as pulmonary hypertension, cor pulmonale, and even heart failure. The aim of this study was to detect the asymptomatic cardiopulmonary changes that could happen in children with adenoid hypertrophy.Eighty children with adenoid hypertrophy were included in this study. Chest x-ray was used to assess the cardiothoracic ratio, whereas echocardiography was used for measuring the pulmonary arterial pressures, right ventricular diastolic filling parameters, and right ventricular end-diastolic diameters. All patients underwent adenoidectomy with or without tonsillectomy, and they were subjected again to echocardiographic assessment 6 months after the operation. No patient showed an increase in the cardiothoracic ratio on x-ray. Preoperative echocardiography showed an increase in pulmonary artery pressure (22.7 [SD, 3.8] mm Hg), a decrease in right ventricular diastolic filling parameters (E/A = 1.03 [SD, 0.17]), and an increase in right ventricular end-diastolic diameters (1.89 [SD, 0.19] cm). Postoperatively, pulmonary artery pressure decreased to 17.2 [SD, 2.1] mm Hg, right ventricular diastolic filling (E/A) increased to 1.25 [SD, 0.11], and right ventricular end-diastolic diameters decreased to 1.68 [SD, 0.12] cm. The comparison between preoperative and postoperative results for each individual parameter was statistically significant. Clinically asymptomatic cardiopulmonary changes due to adenoid hypertrophy are not rare. Early diagnosis and treatment of upper airway obstruction can prevent these serious complications. Echocardiographic examination should be recommended for these patients as a part of preoperative preparation to avoid anesthetic complications.

    Recent development of a non-invasive magnetic resonance examination has increased the opportunity to identify asymptomatic patients with moyamoya disease who have experienced no cerebrovascular events. However, their clinical features, prognosis, and treatment strategy are still unclear because of small number of subjects and short follow-up periods. Therefore, we have designed Asymptomatic Moyamoya Registry (AMORE) study in Japan. The objectives of this nation-wide, multi-center prospective study are to clarify long-term prognosis of asymptomatic patients with moyamoya disease and to determine the risk factors that cause ischemic and hemorrhagic stroke in them. In this article, we review the published data on asymptomatic moyamoya disease and report the on-going multi-center prospective cohort study, AMORE study. We would like to emphasize the importance to determine the clinical features, prognosis, and treatment strategies of asymptomatic moyamoya disease in very near future.

    Brain abscess commonly occurs secondary to an adjacent infection (mostly in the middle ear or paranasal sinuses) or due to hematogenous spread from a distant infection or trauma. Pulmonary arteriovenous fistulas (AVFs) are abnormal direct communications between the pulmonary artery and vein. We present two cases of brain abscess associated with asymptomatic pulmonary AVF. A 65-year-old woman was admitted with a headache and cognitive impairment that aggravated 10 days prior. An magnetic resonance (MR) imaging revealed a brain abscess with severe edema in the right frontal lobe. We performed a craniotomy and abscess removal. Bacteriological culture proved negative. Her chest computed tomography (CT) showed multiple AVFs. Therapeutic embolization of multiple pulmonary AVFs was performed and antibiotics were administered for 8 weeks. A 45-year-old woman presented with a 7-day history of progressive left hemiparesis. She had no remarkable past medical history or family history. On admission, blood examination showed a white blood cell count of 6290 cells/uL and a high sensitive C-reactive protein of 2.62 mg/L. CT and MR imaging with MR spectroscopy revealed an enhancing lesion involving the right motor and sensory cortex with marked perilesional edema that suggested a brain abscess. A chest CT revealed a pulmonary AVF in the right upper lung. The pulmonary AVF was obliterated with embolization. There needs to consider pulmonary AVF as an etiology of cerebral abscess when routine investigations fail to detect a source. PMID:28061502

  2. Management of Asymptomatic Renal Stones in Astronauts

    2016-01-01

    Introduction: Management guidelines were created to screen and manage asymptomatic renal stones in U.S. astronauts. The risks for renal stone formation in astronauts due to bone loss and hypercalcuria are unknown. Astronauts have a stone risk which is about the same as commercial aviation pilots, which is about half that of the general population. However, proper management of this condition is still crucial to mitigate health and mission risks in the spaceflight environment. Methods: An extensive review of the literature and current aeromedical standards for the monitoring and management of renal stones was done. The NASA Flight Medicine Clinic's electronic medical record and Longitudinal Survey of Astronaut Health were also reviewed. Using this work, a screening and management algorithm was created that takes into consideration the unique operational environment of spaceflight. Results: Renal stone screening and management guidelines for astronauts were created based on accepted standards of care, with consideration to the environment of spaceflight. In the proposed algorithm, all astronauts will receive a yearly screening ultrasound for renal calcifications, or mineralized renal material (MRM). Any areas of MRM, 3 millimeters or larger, are considered a positive finding. Three millimeters approaches the detection limit of standard ultrasound, and several studies have shown that any stone that is 3 millimeters or less has an approximately 95 percent chance of spontaneous passage. For mission-assigned astronauts, any positive ultrasound study is followed by low-dose renal computed tomography (CT) scan, and flexible ureteroscopy if CT is positive. Other specific guidelines were also created. Discussion: The term "MRM" is used to account for small areas of calcification that may be outside the renal collecting system, and allows objectivity without otherwise constraining the diagnostic and treatment process for potentially very small calcifications of uncertain

    2012-05-01

    Catecholaminergic polymorphic ventricular tachycardia is a rare genetic disorder caused by mutations in genes involved in the intracellular calcium homeostasis of cardiac cells. Affected patients typically present with life-threatening ventricular arrhythmias precipitated by emotional/physical stress. The diagnosis is based on the demonstration of polymorphic or bidirectional ventricular tachycardia associated with adrenergic stress. Genetic testing can be confirmatory in some patients. Treatment for catecholaminergic polymorphic ventricular tachycardia includes medical and surgical efforts to suppress the effects of epinephrine at the myocardial level and/or modulation of calcium homeostasis. Mortality is high when untreated and sudden cardiac death may be the first manifestation of the disease. First-degree relatives of a proband should be offered genetic testing if the causal mutation is known. If the family mutation is not known, relatives should be clinically evaluated with provocative testing. In the absence of rigorous trials, prophylactic treatment of the asymptomatic catecholaminergic polymorphic ventricular tachycardia patient appears to reduce morbidity and mortality.

    Background. Obesity has reached epidemic proportions in dogs and, as in humans, cost of care has increased due to associated comorbidities. In humans, asymptomatic urinary tract infections (UTI) may be more prevalent in the obese. Asymptomatic bacteriuria (AB) is the term used when UTI are asymptomatic. We hypothesized that morbidly obese dogs are similarly more likely to have asymptomatic bacteriuria than lean, overweight, and moderately obese dogs. Methods. A retrospective study was undertaken to explore a possible association between obesity and asymptomatic bacteriuria. Records from lean, overweight, and obese dogs receiving both a dual energy absorptiometry (DXA) scan and urine culture were included. Results. Six positive urine cultures were identified among 46 dogs fulfilling search criteria. All six positive cultures were found in dogs with body fat percentage of >45%. In dogs with body fat percentage of <45%, there were no positive urine cultures. Discussion. There was an increased prevalence of asymptomatic bacteriuria in the morbidly obese dogs in this study compared to those that were lean, overweight, or moderately obese. Whether antibiotic therapy is necessary in such cases is still being debated, but because asymptomatic bacteriuria may be associated with ascending infections, uroliths, or other complications, the data reported herein support the screening of obese patients for bacteriuria.

    Background Chronic obstructive pulmonary disease (COPD) has a variable natural history and not all individuals follow the same course. This study aimed to identify the prevalence and characteristics of asymptomatic COPD patients from a population-based survey in China.Methods A multistage cluster sampling strategy was used in a population from seven different provinces/cities. All residents (over 40 years old) were interviewed with a standardized questionnaire and spirometry.Post-bronchodilator forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) of less than 70% was defined as the diagnostic criterion of COPD. All COPD patients screened were divided into symptomatic group and asymptomatic group according to the presence or absence of chronic respiratory symptoms. Socio-demographic,personal and exposure variables were collected and analyzed.Results Among the 1668 patients who were diagnosed with COPD from the 25 627 sampling subjects, 589 (35.3%)were asymptomatic. The age, sex, body mass index (BMI),rural and urban distributions, smoking habit and education levels were similar in the two groups. A total of 64.7% of the asymptomatic patients had no comorbidities. Cardiovascular diseases and lung cancer were more common among symptomatic COPD patients than asymptomatic group.Asymptomatic COPD group were less likely to present with poor ventilation in the kitchen, a family history of respiratory disease and recurrent childhood cough. Asymptomatic COPD patients had significantly higher FEV1 (73.1% vs. 61.0%), FVC (91.9% vs. 82.0%), and a higher ratio of FEV1/FVC (62.9% vs.58.7%) (all P <0.001) than symptomatic group. More asymptomatic patients were underdiagnosed (91.9% vs.54.3%, P<0.001) than symptomatic patients.Conclusions This large population-based survey confirmed a high prevalence of asymptomatic COPD patients in China. More use of spirometry screening test may be important to the early detection of COPD.

    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.

    ABI were not correlated with the distance covered on the 6MWT. Conclusion: Asymptomatic PAD is not associated with walking endurance in patients with COPD. Therefore, it is important to detect and treat asymptomatic PAD early so that COPD patients do not progress to become exercise intolerant. Limited by the small sample size and predominantly male (99% population in the study, further large-scale prospective studies are needed to verify the results.

    Dent disease is an X-linked proximal tubulopathy that typically presents with hypercalciuria, low-molecular-weight proteinuria and slow progression to endstage renal disease. We report the case of a 5-year-old boy who presented with asymptomatic nephrotic range proteinuria and was later diagnosed with Dent disease. Absence of specific glomerular pathology in the first kidney biopsy led to erroneous treatment for presumably unsampled primary focal segmental glomerulosclerosis. Aggressive angiotensin blockade and immunosuppression resulted in significant side effects with marginal benefit. The continued nonspecific findings after a second kidney biopsy 2 years later led to the suspicion of a congenital tubulopathy. We detected a novel CLCN5 gene mutation, c.1396G > C, that creates a G466R missense change in the ClC-5 protein. Dent disease should be considered in the differential diagnosis of asymptomatic proteinuria for male patients. Profiling proteinuria in these patients by spot urine albumin/creatinine ratio may give the first clue to a tubulopathy. Determining the extent to which the clinical work-up should proceed for females with Dent phenotype or asymptomatic proteinuria remains to be a challenging clinical dilemma.

    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 CONTEXT: Alcoholism may interfere with nutritional status, but reports are often troubled by uncertainties about ingested diet and organ function, as well as by ongoing abuse and associated conditions. OBJECTIVE: To identify nutritional and body compartment changes in stable alcoholics without confounding clinical and dietetic variables, a prospective observational pilot study was designed. Three well-matched populations were considered: subjects with chronic alcoholic pancreatitis, alcoholics without visceral disease, and healthy never-drinking adults (controls. METHODS: Subjects (n = 60 were asymptomatic males with adequate diet, no superimposed disease or complication, and alcohol-free for at least 6 months. After exclusions, 48 patients were compared. Variables encompassed dietary recall, bioimpedance analysis, biochemical profile and inflammatory markers. Main outcome measures were body fat, lean body mass, serum lipids, C-reactive protein, and selected minerals and vitamins. RESULTS: Both alcoholic populations suffered from reduced lean body mass (P = 0.001, with well-maintained body fat.Magnesium was depleted, and values of vitamin D and B12 correlated with alcohol abuse. LDL and total cholesterol was increased in alcoholics without pancreatitis (P = 0.04, but not in those with visceral damage. C-reactive protein and serum amyloid A correlated with duration of excessive drinking (P = 0.01. CONCLUSIONS: Undernutrition (diminished lean body mass, risk of magnesium and vitamin deficiencies contrasted with dyslipidemia and increased cardiovascular risk. This second danger was masked during chronic pancreatitis but not in alcoholics without visceral disease. Further studies should focus special requirements of this population.

    The role played by vessel disease in stroke-related cognition dysfunction is unclear. We assessed the impact of significant atherosclerotic disease on cognition—even in patients asymptomatic for stroke. We hypothesized that patients would perform poorly relative to controls, but that symptomatic/asymptomatic status (history of stroke/transient ischemic attack) would have no effect. Fifty-two carotid endarterectomy candidates with >60% carotid stenosis and 17 controls underwent a 60-min neuropsychological test protocol. Symptomatic and asymptomatic patients showed deficits in executive function, delayed verbal recall, and general knowledge. Patients symptomatic for stroke also performed worse on tests of language and motor/visuomotor ability. Symptomatic and asymptomatic patients differed in working memory and language task performance. Although all patients showed deficits in executive function and memory, only symptomatic patients showed additional deficits in language and motor function. Cognitive abnormalities in patients viewed as “asymptomatic” for stroke underscore the need for early identification and treatment. PMID:26663810

    We compared clinical and arteriographic features in 106 patients with symptomatic unilateral carotid territory occlusive disease to determine the frequency and distribution of occlusive arterial lesions in asymptomatic vessels. Among black patients who were predominantly from Chicago, young, and female, there were fewer transient ischemic attacks and myocardial infarcts, less claudication, and more asymptomatic lesions of the supraclinoid internal carotid artery, anterior cerebral artery stem, and the middle cerebral artery stem. Among white patients predominantly from New England, elderly, and male, there was more frequent and severe occlusive asymptomatic disease at extracranial carotid and vertebral artery sites. Knowledge of the distribution of asymptomatic lesions will help guide evaluation and treatment strategies for patients with occlusive cerebrovascular disease.

    American cutaneous leishmaniasis (ACL) is a major public health problem caused by vector-borne protozoan intracellular parasites from the genus Leishmania, subgenera Viannia and Leishmania. Asymptomatic infection is the most common outcome after Leishmania inoculation. There is incomplete knowledge of the biological processes explaining the absence of signs or symptoms in most cases while other cases present a variety of clinical findings. Most studies of asymptomatic infection have been conducted in areas of endemic visceral leishmaniasis. In contrast, asymptomatic ACL infection has been neglected. This review is focused on the following: (1) epidemiological studies supporting the existence of asymptomatic ACL infection and (2) immunological studies conducted to understand the mechanisms responsible for controlling the parasite and avoiding tissue damage.

    Full Text Available Urinary Tract Infection (UTI refers to both microbial colonization of the urine and tissue invasion of any structure of the urinary tract. Pregnancy enhances the progression from asymptomatic to symptomatic bacteriuria which could lead to pyelonephritis and adverse obstetric outcomes such as prematurity, low-birth weight, and higher fetal mortality rates. This study was undertaken to determine the prevalence of asymptomatic bacteriuria in pregnancy; its causative agents and their antimicrobial susceptibility pattern, and also to determine the relationship between asymptomatic bacteriuria and pyuria. The total number of participants who finished the study was 392. The mean age of the participants was 29.76 ± 6.71(range, 21-37 years. Of the 392 urine specimens processed, 102 (26.0% showed significant bacteriuria. The commonest organism causing bacteriuria was Escherichia coli. The sensitivity pattern of the isolated organisms revealed that all were sensitive to ciprofloxacin and gentamicin at very high percentage. 200 (51.5% women had more than 5 pus cells in urine specimens from which 50 (12.75% had positive cultures. Women with higher number of pus cells in urine specimen had significantly higher asymptomatic bacteriuria (p < 0.0001.In conclusion, screening of bacteriuria in pregnancy and proper treatment must be considered as an essential part of antenatal care in Nepalese community. To prevent asymptomatic bacteriuria complications, all pregnant women should be screened at the first antenatal visit. A negative test for pyuria is not a reliable indicator of the absence of asymptomatic bacteriuria in pregnant women.

  5. [Is there a role for asymptomatic carotid artery stenosis screening?].

    2014-08-01

    Screening for asymptomatic carotid artery stenosis (CAS) is highly controversial Many surgeons routinely screen their patients for carotid disease prior to major operations, yet the benefit of such practice was never demonstrated. The treatment of symptomatic patients has not changed much during the last twenty years, since the publication of the North American Symptomatic Carotid Endarterectomy Trial (NASCET). However, in contrast, the Asymptomatic Carotid Atherosclerosis Study (ACAS) and the Asymptomatic Carotid Surgery Trial (ACST) failed to get the same acceptance among the multidisciplinary group treating CAS.The prevalence of asymptomatic 60-99% carotid artery stenosis among the general population is about 1%. Neither ACAS nor ACST showed that stenosis severity was associated with increasing stroke risk. The 'realpolitik' is that mass interventions in asymptomatic patients will probably only ever prevent about 1% of all strokes. This is even truer regarding patients scheduLed for major operation, in which the incidence of stroke is less than 1%. Moreover the current evidence in the literature suggests that the best medicaL treatment (BMT) results in 0.5% strokes per year, better than resuLts which can be offered by surgery. According to the current evidence, it seems that asymptomatic carotid artery screening should be discontinued, since it is a major waste of resources.

    Background. Obesity has reached epidemic proportions in dogs and, as in humans, cost of care has increased due to associated comorbidities. In humans, asymptomatic urinary tract infections (UTI) may be more prevalent in the obese. Asymptomatic bacteriuria (AB) is the term used when UTI are asymptomatic. We hypothesized that morbidly obese dogs are similarly more likely to have asymptomatic bacteriuria than lean, overweight, and moderately obese dogs. Methods. A retrospective study was undertaken to explore a possible association between obesity and asymptomatic bacteriuria. Records from lean, overweight, and obese dogs receiving both a dual energy absorptiometry (DXA) scan and urine culture were included. Results. Six positive urine cultures were identified among 46 dogs fulfilling search criteria. All six positive cultures were found in dogs with body fat percentage of >45%. In dogs with body fat percentage of obese dogs in this study compared to those that were lean, overweight, or moderately obese. Whether antibiotic therapy is necessary in such cases is still being debated, but because asymptomatic bacteriuria may be associated with ascending infections, uroliths, or other complications, the data reported herein support the screening of obese patients for bacteriuria.

  7. Prevalence and outcome of asymptomatic bacteriuria in early pregnancy

    2016-12-01

    Full Text Available Background: Bacteriuria is a major risk factor for developing symptomatic urinary tract infection which is associated with significant maternal and fetal risks. Various studies have put a prevalence of asymptomatic bacteriuria between 2-10% in pregnancy. Maternal and fetal complications like gestational hypertension, anaemia, premature delivery, IUGR, and low birth weight are commonly associated with pyelonephritis which occurs as a result of undiagnosed or inadequately treated infections of the urinary tract. The primary objective was to find out the prevalence of asymptomatic bacteriuria in pregnancies less than 28 weeks gestation in our hospital and to study the various adverse pregnancy outcomes in the study group. Methods: This was a cross sectional study done over a period of 12 months at this tertiary care centre in Government sector in Trivandrum, Kerala. A sample size was calculated statistically and 400 women with gestational age less than 28 weeks attending the outpatient department were included in this study. A structured proforma, urine microscopy and urine culture and sensitivity were the study tools. Results: Prevalence of asymptomatic bacteriuria in our study population was 8.25%. Commonest pathogen isolated was E.coli in 57.14% cases. Maternal morbidity was higher in women with asymptomatic bacteriuria (24.2% than those without (12.5%. Fetal morbidity in women with asymptomatic bacteriuria was 24% whereas it was 12.5% in those without it. Preterm labour, preeclampsia and prematurity were the common morbidities noted. Conclusions: Since pregnant women with asymptomatic bacteriuria were at an increased risk of adverse maternal and fetal outcome, routine screening for asymptomatic bacteriuria preferably in the first trimester is highly recommended.

    Full Text Available The best hope of controlling the herpes simplex virus type 1 and type 2 (HSV-1 and HSV-2 pandemic is the development of an effective vaccine. However, in spite of several clinical trials, starting as early as 1920s, no vaccine has been proven sufficiently safe and efficient to warrant commercial development. In recent years, great strides in cellular and molecular immunology have stimulated creative efforts in controlling herpes infection and disease. However, before moving towards new vaccine strategy, it is necessary to answer two fundamental questions: (i why past herpes vaccines have failed? (ii Why the majority of HSV seropositive individuals (i.e., asymptomatic individuals are naturally “protected” exhibiting few or no recurrent clinical disease, while other HSV seropositive individuals (i.e., symptomatic individuals have frequent ocular, orofacial, and/or genital herpes clinical episodes? We recently discovered several discrete sets of HSV-1 symptomatic and asymptomatic epitopes recognized by CD4+ and CD8+ T cells from seropositive symptomatic versus asymptomatic individuals. These asymptomatic epitopes will provide a solid foundation for the development of novel herpes epitope-based vaccine strategy. Here we provide a brief overview of past clinical vaccine trials, outline current progress towards developing a new generation “asymptomatic” clinical herpes vaccines, and discuss future mucosal “asymptomatic” prime-boost vaccines that could optimize local protective immunity.

    The objective of this study was to evaluate the behavior of different tests used for the diagnosis of visceral leishmaniasis (VL) in asymptomatic subjects living in an endemic area. No gold standard is available for the diagnosis of asymptomatic infection with Leishmania. In continuation of a previous study, 1,017 subjects living in a VL-endemic area were clinically reevaluated. Of these, 576 had at least one positive serological test in a first assessment. About 3 years after the first evaluation, none of the subjects had progressed to clinical VL. Among this group, 246 subjects were selected, and five serological tests (enzyme-linked immunosorbent assay p [ELISAp], ELISArK39, ELISArK26, indirect immunofluorescence test [IIFT] using L. amazonensis promastigote antigen, and an immunochromatographic test using rK39 antigen [TRALd]) and the Montenegro skin test (MST) were repeated. There was a significant increase in the number of subjects who tested positive in the MST, IIFT, ELISAp, and ELISArK39 in the second evaluation. For all tests, there were subjects who tested positive in the first evaluation and negative in the second evaluation. A positive result in the serological tests and MST in subjects from the endemic area studied did not indicate a risk of progression to VL and may only be temporary. PMID:21292896

    Full Text Available Asymptomatic bacteriuria is prevalent during pregnancy. It can lead to pyelonephritis, premature pregnancy and low birth weight. In this prospective study, to determine prevalence and risk factors of asymptomatic bacteriuria, 205 consecutive pregnant women who visited our prenatal care clinic in Mirza-Koochakkhan Hospital and had no urinary symptom were entered. Patients data were recorded using a questionnaire and urine samples were obtained for urinalysis and urine culture. We analysed data by using fisher exact and chi-squared test. 14 cases had positive urine culture (6.8%. Significant correlation was seen between asymptomatic bacteriuria and age, parity, past history of kidney stone, pyelonephritis, urinary tract infection, preterm delivery and pyuria pvalue <0.05. We suggest routine urine culture in first visit of high risk and 16th week of low risk pregnancies.

An evaluation of efficacy of the management of urinary tract infections by using local forms of Estriol in postmenopausal women with type II diabetes and asymptomatic bacteriuria.Material and methods. The study was conducted in two stages. The first stage: a prospective cross–sectional study to identify patients with asymptomatic bacteriuria. During this stage, 414 postmenopausal women with type II diabetes, but without clinical symptoms of urinary tract infection, were investigated. In the second stage, women with asymptomatic bacteriuria (87 women were randomized to two groups: the first group was the main group receiving 0.5 mg of Estriol as a vaginal cream, the second group was the control group. The study lasted 12 months.Results. After 12 months of the study, asymptomatic bacteriuria was revealed in 19.4% of women in the group 1 and 68.4% of women in the group 2 (р <0.001, and symptomatic urinary tract infection in 8.3% of women in the group 1 and 18.4% of women in the group 2 (р <0.001. There was no connection revealed between asymptomatic bacteriuria and НвА1с. Using Estriol in group 1 led to an increase in VHI, the appearance of lactobacilli in the vaginal smear, and the decrease of symptom frequency in atrophic vaginitis. In group 2, there were no significant changes revealed.Conclusions. Usage of local forms of Estriol effectively prevents and decreases the frequency of asymptomatic bacteriuria and urinary tract infection in postmenopausal women suffering with diabetesmellitus.

    Many clinical and research findings converge to indicate that frontal lobe, basal ganglia, and related neuronal connections are primarily involved in human immunodeficiency virus (HIV) infection; frontal lobe, mainly the prefrontal cortex, has a specialized role in working memory processes. This study focused on neuropsychological evaluation of the spatial component of working memory in a sample of 34 asymptomatic HIV-infected subjects as compared with 34 age- and sex-matched seronegative control subjects. A computer-administered test assessing spatial working memory was used for the neuropsychological evaluation. The findings did not show any spatial working memory impairment during the asymptomatic phase of HIV infection.

    This article discusses the merits of electrophysiology study (EPS) and/or ablation for asymptomatic preexcitation Wolff-Parkinson-White (WPW) ECG pattern. Sudden deaths in asymptomatic patients are too few to merit broad screening and aggressive intervention. It also discusses the risks of ablation and the low predictive accuracy of EPS. When WPW is an incidental finding, the decision to proceed with investigation and ablation can be made considering patients' situations and preferences. An invasive strategy is targeted at patients concerned about the low risk of life-threatening arrhythmia as a first presentation after a discussion of the risks and benefits.

    In this study we investigated the bone scan pattern in a homogeneous group of asymptomatic patients implanted with the same type of total knee arthroplasty (TKA) and with a minimum follow-up of 2 years. Twenty-nine patients (21 females, 8 males, mean age 62 years), with a total of 30 uncemented Hofmann TKAs, were entered in the study. The time interval from surgery to scintigraphic evaluation ranged from 2 to 4 years. Bone scan was performed using the three-phase technique and images were interpreted by visual analysis using a three-point scale for the dynamic and blood pool phases and a five-point scale for the bone phase. Areas of increased periprosthetic technetium-99m methylene diphosphonate (MDP) uptake were observed until 4 years after surgery. However, comparing the TKAs implanted 2, 3 and 4 years previously, a decreasing pattern in tracer uptake intensity was noted this being more evident in the femoral and lateral tibial components. In some cases, a persistently elevated tracer uptake, not exceeding a moderate grade, was found in the medial tibial component. In conclusion, increased periprosthetic {sup 99m}TC-MDP uptake is a common finding in asymptomatic uncemented Hofmann TKAs for a prolonged period after surgery, but the uptake intensity is generally mild or moderate and shows a characteristic decreasing pattern over time. Furthermore, in contrast with other types of asymptomatic knee implants previously investigated, no case of high or very high bone uptake was recorded with this type of implant. We may speculate that scintigraphic parameters of normality, and pathology, should be determined for each type of TKA. It is likely that, with the uncemented Hofmann TKA, a high or very high tracer uptake or a progressive increase in the uptake intensity is suggestive of the presence of complications. (orig.)

    Full Text Available Abstract Background Postoperative asymptomatic deep venous thromboses (ADVT can give rise to posttthrombotic syndrome (PTS, but there are still many unresolved issues in this context. For example, there is a lack of knowledge regarding the fate of small ADVT following minor orthopedic surgery. This follow-up study evaluates postthrombotic changes and clinical manifestations of PTS in a group of patients with asymptomatic calf vein DVT after surgery for Achilles tendon rupture. Methods Forty-six consecutive patients with distal ADVT were contacted and enrolled in a follow-up consisting of a single visit at the hospital at a mean time of 5 years postoperatively, including clinical examination and scoring, ultrasonography and venous plethysmography. All patients had participated in DVT-screening with colour duplex ultrasound (CDU 3 and 6 weeks postoperatively and 80% of them were treated with anticoagulation. Results With CDU postthrombotic changes and deep venous reflux were detected at follow-up in more than 50% of the patients, more commonly in somewhat larger calf DVT:s initially affecting more than one vessel. However, only about 10% of the patients had significant venous reflux according to venous plethysmography. No patient had plethysmographic evidence of remaining outflow obstruction, but presence of postthrombotic changes shown with CDU negatively influenced venous outflow capacity measured with plethysmography. A clinical entity of PTS was rarely found and occurred only in two patients (4% and then classified by Villalta scoring as of mild degree with few clinical signs of disease. Distal ADVT:s detected in the early postoperative period (3 weeks showed DVT-progression in 75% of the limbs that were still immobilized and without anticoagulation. Conclusions Asymptomatic postoperative distal DVT:s following surgery for Achilles tendon rupture have a good prognosis and a favourable clinical outcome. In our material of 46 patients the

    Parasitic diseases suppose an important health problem in people from high endemic areas, so these must be discarded properly. Usually, these infections develop asymptomatically but, in propitious situations, are likely to reactivate themselves and can cause clinical symptoms and/or complications in the receiving country. Moreover, in some cases it is possible local transmission. Early diagnosis of these parasitic diseases made by appropriate parasitological techniques and its specific treatment will benefit both, the individual and the community. These techniques must be selected according to geoepidemiological criteria, patient's origin, migration route or time spent outside the endemic area; but other factors must also be considered as its sensitivity and specificity, implementation experience and availability. Given the high prevalence of intestinal parasites on asymptomatic immigrants, it is recommended to conduct a study by coproparasitological techniques. Because of its potential severity, the screening of asymptomatic malaria with sensitive techniques such as PCR (polymerase chain reaction) is also advisable. Serological screening for Chagas disease should be performed on all Latin American immigrants, except for people from the Caribbean islands. Other important parasites, which should be excluded, are filariasis and urinary schistosomiasis, by using microscopic examination. The aim of this paper is to review the different techniques for the screening of parasitic diseases and its advices within the care protocols for asymptomatic immigrants.

    2012-06-01

    Full Text Available The endoscopic finding of ileal ulcers, alone or in small number, is not usual, but when it occurs in asymptomatic patients, an impasse may be generated regarding the action to be taken, since the medical literature is unclear as to how to proceed in this situation. OBJECTIVE: Evaluate patients with ileal ulcers, single or in a small number, asymptomatic, and their follow-up. METHODS: The author reports a series of asymptomatic cases (23 patients of ulcers - single or in small number - found in colonoscopy exams performed for other reasons than typical clinical manifestations of Crohn's disease. RESULTS: Most patients were not treated and remained asymptomatic during the follow-up period. CONCLUSIONS: The patients remained asymptomatic and without treatment in most cases, and, considering the small number of cases and the short observation time, this study does not allow to conclude that this is the best practice in case of asymptomatic patients with ileal ulcer.O achado endoscópico de úlceras ileais, isoladas ou em pequeno número, não é frequente, mas quando ocorre em pacientes assintomáticos pode gerar um impasse quanto à conduta a ser tomada, já que a literatura médica não é clara quanto a como se proceder nessa situação. OBJETIVO: Avaliar pacientes que apresentaram úlceras ileais solitárias ou em pequena quantidade, assintomáticos e a evolução clínica dos mesmos. MÉTODOS: O autor relata uma série de casos (23 pacientes assintomáticos que apresentaram úlceras ileais únicas ou em pequeno número em colonoscopias realizadas por outros motivos que não manifestações clínicas típicas de doença de Crohn. RESULTADOS: A maioria dos pacientes não foi tratada e permaneceu assintomática pelo período de acompanhamento. CONCLUSÕES: Os pacientes permaneceram assintomáticos e sem tratamento em sua maioria, salientando-se o reduzido número de casos e o curto tempo de observação, de modo a não permitirem a este estudo

    2013-08-01

    A 40 year-old woman presented to hospital with 12h of progressive shortness of breath. She was 11 days postpartum, having delivered a full-term male infant. She was discharged on antibiotics for presumed pneumonia, but represented two days later with NYHA class IV symptoms and in acute decompensated heart failure confirmed on clinical examination and chest X-ray. Echocardiography showed a left ventricular ejection fraction (LVEF) of 20%. She was treated for peripartum cardiomyopathy (PPCM) with angiotensin converting enzyme inhibitors (ACEi), beta-blockers and diuretics with normalisation of her cardiac function within six months. Four years later, her son was diagnosed with Duchenne muscular dystrophy (DMD) and she tested positive as a carrier of the mutant gene. It is unclear whether the DMD carrier state alone is associated with increased susceptibility to PPCM or if this is merely the first expression of cardiomyopathy in a previously asymptomatic carrier.

    Throughout the history of the HIV epidemic, HIV-positive patients with relatively high CD4 counts and no clinical features of opportunistic infections have been classified as "asymptomatic" by definition and treatment guidelines. This classification, however, does not take into consideration the array of symptoms that an HIV-positive person can experience long before progressing to AIDS. This short report describes two international multi-site studies conducted in 2003-2005 and 2005-2007. The results from the studies show that HIV-positive people may experience symptoms throughout the trajectory of their disease, regardless of CD4 count or classification. Providers should discuss symptoms and symptom management with their clients at all stages of the disease.

    Full Text Available Congenital sternal defects are rare deformities frequently associated with other anomalies of the chest wall and other organ systems. Although pectus excavatum, pectus carinatum, and cleft sternum can present as isolated deformity, in most cases they are associated with heart and inner organs anomalies and described as symptoms of syndromes like Marfan syndrome, Noonan syndrome, Poland anomaly, and Cantrell pentalogy. In contrast, the etiology of an isolated defect is not well understood. We observed a short sternum (dysmorphic manubrium, hypoplastic body, and complete absence of the xiphoid process in a completely asymptomatic 13-year-old woman. A comprehensive instrumental exams panel was performed to exclude associated anomalies of the heart and of the other organ systems. The patient was completely asymptomatic and she did not need any medical or surgical treatment. To our knowledge, this is the first case of isolated short sternum reported in literature.

  1. Advanced Asymptomatic Carotid Disease and Cognitive Impairment: An Understated Link?

    Directory of Open Access Journals (Sweden)

    Irena Martinić-Popović

    2012-01-01

    Full Text Available Advanced carotid disease is known to be associated with symptomatic cerebrovascular diseases, such as stroke or transient ischemic attack (TIA, as well as with poststroke cognitive impairment. However, cognitive decline often occurs in patients with advanced carotid stenosis without clinically evident stroke or TIA, so it is also suspected to be an independent risk factor for dementia. Neurosonological methods enable simple and noninvasive assessment of carotid stenosis in patients at risk of advanced atherosclerosis. Cognitive status in patients diagnosed with advanced carotid stenosis is routinely not taken into consideration, although if cognitive impairment is present, such patients should probably be called symptomatic. In this paper, we discuss results of some most important studies that investigated cognitive status of patients with asymptomatic advanced carotid disease and possible mechanisms involved in the causal relationship between asymptomatic advanced carotid disease and cognitive decline.

    Full Text Available The aortopulmonary window (APW is an abnormal communication between the ascending aorta and the pulmonary trunk in the presence of two separate semilunar valves. It is a rare congenital malformation which represents 0.1% of all congenital cardiac diseases. Herein, we report a very rare case of 27-year-old patient with unrepaired APW causing Eisenmenger syndrome and pulmonary hypertension who was asymptomatic until her first pregnancy. The median survival of uncorrected APW is 33 years. Aortopulmonary window is a very rare congenital anomaly. To our knowledge, asymptomatic adult case has not been reported until now. APW should be considered in the differential diagnosis of the severe pulmonary hypertension also in adult patients.

    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 objective of this survey was to describe life insurance underwriting practices concerning children with asymptomatic hematuria and proteinuria. A questionnaire was sent to 200 companies licensed to issue life insurance policies in the state of New York. The medical director of each company was asked to respond to the insurability of children with asymptomatic hematuria and proteinuria. Two case summaries were provided with the questionnaire. Of 97 companies, 66 would offer insurance to the patient with hematuria, although 38 (58%) would charge additional premiums. In response to the problem of proteinuria, 61 companies would offer life insurance, although 50 (82%) would require higher premium charges (P life insurance, although often at higher cost. Invasive diagnostic tests are not necessary for insurers to offer insurance.

    Background. Cysts in the larynx are rare and generally asymptomatic. However, large cysts in adults can be symptomatic. If they are symptomatic, they typically present with respiratory and feeding difficulties. They are usually benign in terms of pathology. Several surgical techniques may be used for treatment. Case Report. A 56-year-old man presented to our clinic with hoarseness. Routine laryngeal examination revealed a giant mass and the larynx could not be visualized. At magnetic resonance imaging (MRI), a cystic mass originating from the vallecula was detected. There was no pathology at the glottic level. We planned tracheotomy for the airway and endoscopic surgery for excision. The mass was excised using CO2 laser and was reported as benign. Conclusion. An asymptomatic vallecular cyst may cause difficult intubation in any operation. It may also cause respiratory or other complications. Airway management should be led by an ear, nose, and throat surgeon, since tracheotomy may be required. Endoscopic excision with CO2 laser is a good choice for treatment in elective cases. In this report, we discuss the diagnosis and treatment of a patient with an asymptomatic giant vallecular cyst. PMID:26688767

    To evaluate the spectrum and frequency of MR findings of the first metatarsophalangeal joint (MTPJ) in asymptomatic volunteers. MR imaging of 30 asymptomatic forefeet was performed with a dedicated extremity 1.5-Tesla system. Participants were between 20 and 49 years of age (mean ± SD: 35.5 ± 8.4 years). Two radiologists assessed cartilage, bone, capsuloligamentous structures, and tendons of first MTPJs on MR images. Cartilage defects were observed in 27 % (n = 8) of first MTPJs, most frequently located at the base of the proximal phalanx (23 %, n = 7), whereas cartilage defects of the metatarsal head (13 %, n = 4) and the metatarsosesamoid compartment were rare (0 %-3 %, n = 0-1). Bone marrow oedema-like signal changes were present in 37 % (n = 11) and subchondral cysts in 20 % (n = 6) of first MTPJs. Hyperintense areas on intermediate-weighted sequences (range: 30-43 %, n = 9-13) and on fluid-sensitive sequences with fat suppression (range: 33-60 %, n = 10-18) within the medial and lateral collateral ligament complex were common. Plantar recesses (77 %, n = 23) and distal dorsal recesses (87 %, n = 26) were frequently observed. Cartilage defects, bone marrow oedema-like signal changes, subchondral cysts, plantar recesses, and distal dorsal recesses were common findings on MRI of first MTPJs in asymptomatic volunteers. The collateral ligaments were often heterogeneous in structure and showed increased signal intensity. (orig.)

    Despite great efforts in experimental and clinical research,the prognosis of pancreatic cancer (PC) has not changed significantly for decades.Detection of pre-invasive lesions or early-stage PC with small resectable cancers in asymptomatic individuals remains one of the most promising approaches to substantially improve the overall outcome of PC.Therefore,screening programs have been proposed to identify curable lesions especially in individuals with a familial or genetic predisposition for PC.In this regard,Canto et al recently contributed an important article comparing computed tomography,magnetic resonance imaging,and endoscopic ultrasound for the screening of 216 asymptomatic high-risk individuals (HRI).Pancreatic lesions were detected in 92 of 216 asymptomatic HRI (42.6%).The high diagnostic yield in this study raises several questions that need to be answered of which two will be discussed in detail in this commentary:First:which imaging test should be performed? Second and most importantly:what are we doing with incidentally detected pancreatic lesions? Which ones can be observed and which ones need to be resected?

    Full Text Available Abstract Background In July 2005 an outbreak of acute gastroenteritis occurred on a residential summer camp in the province of Barcelona (northeast of Spain. Forty-four people were affected among residents and employees. All of them had in common a meal at lunch time on 13 July (paella, round of beef and fruit. The aim of this study was to investigate a foodborne norovirus outbreak that occurred in the residential summer camp and in which the implication of a food handler was demonstrated by laboratory tests. Methods A retrospective cohort study was designed. Personal or telephone interview was carried out to collect demographic, clinical and microbiological data of the exposed people, as well as food consumption in the suspected lunch. Food handlers of the mentioned summer camp were interviewed. Ten stool samples were requested from symptomatic exposed residents and the three food handlers that prepared the suspected food. Stools were tested for bacteries and noroviruses. Norovirus was detected using RT-PCR and sequence analysis. Attack rate, relative risks (RR and its 95% confidence intervals (CI were calculated to assess the association between food consumption and disease. Results The global attack rate of the outbreak was 55%. The main symptoms were abdominal pain (90%, nausea (85%, vomiting (70% and diarrhoea (42.5%. The disease remitted in 24-48 hours. Norovirus was detected in seven faecal samples, one of them was from an asymptomatic food handler who had not eaten the suspected food (round of beef, but cooked and served the lunch. Analysis of the two suspected foods isolated no pathogenic bacteria and detected no viruses. Molecular analysis showed that the viral strain was the same in ill patients and in the asymptomatic food handler (genotype GII.2 Melksham-like. Conclusions In outbreaks of foodborne disease, the search for viruses in affected patients and all food handlers, even in those that are asymptomatic, is essential. Health

  10. Education, individual time preferences, and asymptomatic disease detection.

    Asymptomatic conditions such as hypertension are generally hard to diagnose, absent routine medical examinations. This is especially problematic in developing countries, where most citizens do not engage in routine examinations due to limited economic resources. We study the roles of education and individual time preferences in asymptomatic disease detection and management. Using discrete choice models on a sample of 4209 hypertensive Indonesian adults surveyed between November 2007 and April 2008, we find that both education and individual time preferences play important roles. However, the effects are different for people in good health than they are for people in bad health. Education does not seem to matter for disease detection when respondents are in good general health, and its effects on disease management vary largely in magnitudes between these groups. In terms of disease detection, more educated respondents have a higher probability of being diagnosed, but only conditional on being in poor general health. Time preferences, on the other hand, matter for respondents in good general health, but the effect is not significant for those in bad health. More impatient respondents that are in good health have a higher probability of being under-diagnosed because they are more likely to forgo routine physicals. The findings point to two distinct channels through which education can affect health, and suggest that different types of policies need to be implemented, in order to reach the entire population. Traditional programs that stimulate education and improve the socio-economic status of individuals in developing countries are helpful, but they do not address the whole problem. Besides its more usual positive effects, education can also negatively affect the health of asymptomatic patients, because it reflects a higher opportunity cost of engaging in preventative health screenings.

    AIM: To investigate the presence of M2 antibodies specific for pdmary biliary cirrhosis (PBC) in asymptomatic Chinese and identify patients with early PBC.METHODS: Enzyme-linked immunosorbent assay (ElISA)tests for M2 antibodies to recombinant protein were performed in 5 011 subjects (age range, 26-85 years; mean age: 45.81±15.02 years) who took an annual physical examination. M2-positive subjects were further analyzed for immunoglobulin (Ig) classes and subclasses of M2 antibodies.Clinical, biochemical and immunological data were obtained for M2-positive subjects. In addition, ultrasonography (US)or endoscopic retrograde cholangio-pancreatography (ERCP)was performed to exclude any disorders other than PBC.RESULTS: M2 antibodies were detected in 8 (0.16%) of the 5 0LL subjects studied. Of the 8 subjects, 7 were female and 1 was male (age range: 40-74 years). An unexplained increase of serum alkaline phosphatase (ALP) and gamma glutamyl transpeptidase (γ-GT) values, often to striking levels,was detected in 4 M2-positive subjects, 3 of them accorded with the diagnostic criteria recommended by the American Association for the Study of Liver Diseases, even though they had no symptoms of PBC (such as fatigue, pruritus or jaundice).Liver biopsy was performed in two M2-positive subjects and the histology was compatible with PBC in both cases.CONCLUSION: Our data, while not assessing the true prevalence of asymptomatic PBC in the general population,suggest that asymptomatic PBC is much more common in China than has been supposed.

    Full Text Available Granuloma annulare (GA is a benign inflammatory dermatosis of unknown cause, characterized by necrobiotic dermal papules. Several morphologic forms of GA including localized, disseminated, linear, nodular, perforating, subcutaneous, pustular and arcuate dermal erythema have been reported in the literature. Disseminated GA, a rarely seen form, has been reported in association with some hematopoietic and solid malignancies; however, it has been suggested that the exact causative relationship between malignancy and GA is unclear. We present here a 66-year-old female patient with disseminated GA associated with asymptomatic multipl myeloma.

    MRI of the cervical spine for evaluation concerning degenerative lesions was performed on asymptomatic experienced military high performance aircraft pilots (mean age 42 yr with mean accumulated flying time of 2600 h), and for comparison on age-matched controls without military flying experience. Young military high performance aircraft pilots (mean age 23 yr with 220 h of flying per person) were also examined. There were significantly more osteophytes, disk protrusions, compressions of the spinal cord and foraminal stenoses in the experienced pilots than in the age-matched controls. Low frequency of low grade degenerative lesions was found in the young and inexperienced pilots.

    Primary cardiac tumors are very rare, atrial myxoma being the most common benign tumor of the heart. They may present with a great variety of incidental asymptomatic masses to severe life-threatening cardiovascular complications necessitating emergency surgery. Here we report the diagnostic evaluation and successful surgical resection of such a giant cardiac tumor which was found on a routine medical check-up in a 62-year-old patient. Histology confirmed diagnosis of unusually huge myxoma. This article demonstrates it’s necessary to include cardiac tumors in the differential diagnosis of subtle and non-specific cardiothoracic symptoms. PMID:25120848

    Spinal arachnoiditis is one of the common and disabling complication of tuberculous meningitis (TBM). We focused on early diagnosis of spinal arachnoiditis by spinal MRI in asymptomatic patients in whom neurological examination was normal. We studied 16 patients with a diagnosis of probable or highly probable TBM with symptoms for less than 1 month; three had radiological evidence of spinal arachnoiditis. High cerebrospinal fluid protein appeared to be a risk factor for development of spinal arachnoiditis. MRI is sensitive to detect early spinal arachnoiditis. Earlier diagnosis may be helpful in management of spinal arachnoiditis in TBM. (orig.)

    Pancreatic infiltration of leukemic cells is a very rare manifestation at the onset of acute lymphoblastic leukemia (ALL) in childhood. Pancreatic enlargement in this situation is unusual and pancreatic involvement is often associated with biliary obstruction, cholestasis and pancreatitis. We report a 3-month-old girl who presented with asymptomatic leukemic infiltration of the pancreas, demonstrated by US with heterogeneous pancreatic enlargement associated with multiple hypoechogenic lesions, without cholestasis. Although these manifestations are rare, ALL should be considered a cause of pancreatic enlargement.

    Full Text Available BACKGROUND UTI is the most frequent medical complication. It may be asymptomatic or symptomatic. Asymptomatic bacteriuria if left untreated might result in symptomatic UTI and adverse pregnancy outcomes. AIM This prospective study was aimed to determine the prevalence of Asymptomatic bacteriuria of pregnancy among antenatal women attending the antenatal clinic in the Department of Obstetrics and Gynaecology, Maharajah’s Institute of Medical Sciences, Nellimarla, Vizianagaram District, Andhra Pradesh. MATERIAL AND METHODS After taking approval from Institutional Ethics Committee and informed written consent from patients, urine samples were collected from antenatal women in their first antenatal visit. A clean catch midstream specimen of urine was collected and inoculated on blood agar and MacConkey’s agar. It was incubated aerobically at 37 degrees centigrade overnight. Isolates were identified up to species level using standard protocol and sensitivity to different antibiotics is tested. Results were analysed statistically and a P value of less than 0.05 was taken as significant. RESULTS A total of 173 samples were screened; 154 women showed no growth on culture; 19 women had significant bacteriuria with a prevalence rate of 10.98%; 15 women in the age group of 18-25 years and 4 women in the age group of 26-35 years had significant bacteriuria; 83 women were multiparous and 11 (57.89% women in this group had significant bacteriuria, while only 8 (42.1% out of 90 women in the nulliparous group had significant bacteriuria. With respect to trimester, 10 (52.63% out of 19 culture positive cases were in second trimester. In our study, the organisms isolated were Escherichia coli, Staphylococcus aureus and Klebsiella pneumoniae. The bacteria grown were most sensitive to Ampicillin+Sulbactam (68%, Nitrofurantoin (73%, Amikacin (84% and Meropenem (100%. CONCLUSION It is therefore essential to screen every antenatal women for asymptomatic

    Of patients diagnosed with prostate cancer, 0% to 20% experience disease progression to metastatic castration-resistant prostate cancer (mCRPC). Recently, 4 novel therapies have been introduced for the treatment of mCRPC; of these, abiraterone and sipuleucel-T have been studied in the asymptomatic, pre-docetaxel population. Both have shown clinical benefits compared with placebo. This study evaluated the cost-effectiveness of abiraterone acetate and sipuleucel-T compared with prednisone in asymptomatic, pre-docetaxel mCRPC from a US societal perspective. A Markov model was constructed to simulate stable disease, progressed disease, and death. Survival and event rates were derived from published clinical trial data. Costs were derived from the literature and government reimbursement schedules. Outcomes were measured as average cost-effectiveness ratios (ACERs), incremental cost-effectiveness ratios (ICERs), and net monetary benefits (NMBs). One-way and probabilistic sensitivity analyses were conducted to test the robustness of the model. The base-case ACER was $114K/quality-adjusted life-years (QALY) for abiraterone, $85K/QALY for sipuleucel-T, and $31K/QALY for prednisone. The base-case ICER was $389K/QALY for abiraterone and $547K/QALY for sipuleucel-T. Prednisone dominates both abiraterone and sipuleucel-T in terms of NMB at willingness-to-pay (WTP) thresholds of $400K or less. One-way sensitivity analyses revealed that the model was most sensitive to overall survival and utility inputs. Probabilistic sensitivity analyses showed abiraterone to be cost-effective 50% or more of the time at a WTP of greater than $400K, whereas sipuleucel-T was cost-effective 50% or more of the time at a WTP of greater than $270K. Neither abiraterone nor sipuleucel-T was found to be cost-effective compared with prednisone in the treatment of asymptomatic, pre-docetaxel mCRPC.

    Cryptococcus neoformans is the third most common cause of invasive fungal infections in solid organ transplantation. The infection generally presents as disseminated disease, involving multiple sites including the central nervous system, lungs, and skin. An increase in the incidence of primary pulmonary cryptococcal infections has been reported recently in solid organ recipients; these infections were generally symptomatic with an accelerated clinical course. We report four cases of asymptomatic pulmonary cryptococcosis in solid organ recipients (kidney, n=2, heart, n=2). In each case, an incidental finding on a routine chest radiograph led to the microbiological or histopathological diagnosis of invasive pulmonary C. neoformans infection. In these patients, cryptococcosis occurred a median of 25 months (range 7-36 months) after organ transplantation. All patients had a calcineurin inhibitor, prednisone, and azathioprine or mycophenolate mofetil as part of their immunosuppressive therapy at the time of diagnosis. Serum cryptococcal antigen was available and positive in the three patients studied; assessment of cerebrospinal fluid (CSF) of all four patients revealed no organisms by smear or culture. Therapy consisted of oral fluconazole in all cases, with flucytosine in one case, combined with resection of lung tissue in two individuals. All patients have remained free of cryptococcal disease (follow-up median 42 months, from 18 to 88 months). Cryptococcal disease in solid organ recipients may present as asymptomatic, localized pulmonary disease. The natural history of such infections is unknown. New pulmonary radiographic findings should prompt an aggressive diagnostic evaluation including serum and CSF cryptococcal antigen assays, and a biopsy of pulmonary lesions. Prolonged therapy may be used to reduce the risk of progression and dissemination during periods of intensified immune suppression.

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.

    Dental instrumentation has long provided insight into the mechanism of musculo-skeletal function of the gnathic system. While large population studies associate dental arch displacement (DAD), especially laterally, with symptoms, mandibular condyle displacement (CD) resulting from DAD has not been targeted as possibly etiologic in the production of common muscle contraction headache (CMCH) and temporo-mandibular dysfunction (TMD). The objective was to evaluate the three-dimensional nature of DAD and CD between the seated condylar position (SCP) and the intercuspal position (ICP) and to compare results derived from large deprogrammed asymptomatic and symptomatic populations. A total of 1 192 sets of dental casts collected from asymptomatic and symptomatic populations were articulated in the SCP. The initial occlusal contact, DAD, and condylar displacement were evaluated for frequency, direction, and magnitude of displacement between the SCP and ICP. The data revealed significant displacement between the SCP and ICP of the condyles (displaced most frequently inferior (down) and posterior (distal)) and substantially increased frequency and magnitude of displacement of the dental arches (with posterior premature occlusal contacts, increased overjet, decreased overbite, midline differences, and occlusal classification changes) in symptomatic subjects. These discrepancies were statistically significant and clinically significant. The data support the concept of increased DAD and CD with dysfunction. Transverse condylar displacement, commonly presenting with dental cross bite, may be associated with CMCH and TMD. Displacement of the mandibular condyle may be an etiologic factor in CMCH and dysfunction of the temporo-mandibular joint. PMID:27357324

    This study investigated sensory and motor nerve excitability properties to elucidate the development of diabetic neuropathy. A total of 109 type 2 diabetes patients were recruited, and 106 were analyzed. According to neuropathy severity, patients were categorized into G0, G1, and G2+3 groups using the total neuropathy score-reduced (TNSr). Patients in the G0 group were asymptomatic and had a TNSr score of 0. Sensory and motor nerve excitability data from diabetic patients were compared with data from 33 healthy controls. Clinical assessment, nerve conduction studies, and sensory and motor nerve excitability testing data were analyzed to determine axonal dysfunction in diabetic neuropathy. In the G0 group, sensory excitability testing revealed increased stimulus for the 50% sensory nerve action potential (Pmotor excitability only had significantly increased stimulus for the 50% compound motor nerve action potential (Pdevelopment of axonal dysfunction in sensory axons occurred prior to and in a different fashion from motor axons. Additionally, sensory nerve excitability tests can detect axonal dysfunction even in asymptomatic patients. These insights further our understanding of diabetic neuropathy and enable the early detection of sensory axonal abnormalities, which may provide a basis for neuroprotective therapeutic approaches.

    Presence of monoclonal immunoglobulin in serum or urine is a relatively common event affecting about 3.2 % of people over 50. Isolated increase of only one type of free light chain, either κ or λ, is detected in 0.7-0.8 % of people over 50. Most people with monoclonal immunoglobulin meet the criteria of the so-called "mono-clonal gammopathy of undetermined significance (MGUS)". MGUS is defined by concentration of monoclonal immunoglobulin in serum < 30 g/l, number of plasma cells in the bone marrow < 10 % and the absence of symptoms of multiple myeloma and other lymphoproliferative diseases. A proportion of people with MGUS gradually progresses from asymptomatic into symptomatic myeloma or other malignant lymphoproliferative disease requiring treatment. Therefore, MGUS is considered to be one of the most common premalignant conditions with an average risk of transformation into malignant disease of 1 % per year. Monoclonal gammopathy of IgG and IgA subtype can develop into multiple myeloma. Light chain monoclonal gammopathy can develop not only into light chain multiple myeloma but also into AL-amyloidosis and light chain deposition disease (amorphous deposits of light chains damaging organs). IgM monoclonal gammopathy may develop into Waldenstrom macroglobulinemia or other lymphoproliferative disorder, or into rare IgM subtype of multiple myeloma. Unfortunately, people with MGUS are threatened by more than an increased risk of transformation into multiple myeloma or other severe hematologic disease. Pre-malignant clone of plasma cells in the bone marrow causes changes in the bone marrow that directly affect the person. For people with MGUS, there is an increased incidence of osteoporosis and increased fracture risk when compared to the general population. People with MGUS also have an increased risk of bacterial infections and thromboembolic complications compared with the same age population without MGUS. Clonal plasma cells, which are the basis of MGUS, may in

    Objective: The purpose of our study was to describe the magnetic resonance imaging (MRI) features of bipartite patella in asymptomatic patients. Materials and methods: The study was prospective in type and performed following institutional ethical committees approval. In total, 25 subjects were recruited into the study and informed consent obtained in each case. The local radiology database was utilised in conjunction with a clinical questionnaire to identify patients who had asymptomatic bipartite patella. Any patient with a history of trauma or symptomatic disease was excluded from the study. MRI imaging was performed in each case on a 1.5 T system using a dedicated knee coil and a standardised knee protocol. The images obtained were then analysed by two musculoskeletal radiologists in consensus. Results: Of the 25 subjects, there were 8 females and 17 males. The mean age was 34.6 years. All but one of the bipartite fragments were located on the superolateral aspect of the patella. In 23 cases, one fragment was identified. The average transverse diameter of the fragment was 12.8 mm. The average distance between the fragment and the adjacent patella in the axial plane was 1.46 mm. In addition, the cartilage overlying the patella and accessory fragment was intact in all cases. The average thickness of the patella cartilage at its border to the fragment was 2.4 mm with an average ratio of the cartilage thickness of the fragment as compared with the cartilage thickness of the patella of 0.72. There was no evidence of high signal or bone marrow oedema on fluid sensitive sequences within either the patella or the fragment in any of the patients. Fluid was identified in the cleft between the patella and the fragment in the majority of cases. Conclusions: Asymptomatic bipartite patella is characterised by intact but thinned cartilage along the border between the patella and the fragment, fluid between the cleft and a lack of any bone marrow oedema or high signal within

    2016-03-01

    Full Text Available Esophagogastroduodenoscopy (EGD is regarded as a relatively safe procedure; however, it carries a very low incidence of severe adverse events. Perforation is a rare complication of EGD, and it may further lead to pneumoperitoneum or pneumoretroperitoneum. The occurrence of large bowel perforation after EGD is extremely rare, and it has never been reported in the international literature. Herein, we present a case of concurrence of pneumoperitoneum and pneumoretroperitoneum as a result of sigmoid perforation after EGD. In our case, the probable mechanism of the perforation may have stemmed from the excessive inflation of air that passed through the gastrointestinal tract to the sigmoid colon, causing the increased intraluminal pressure, and then prompting a healed asymptomatic diverticulitis leak again.

    2008-01-01

    Occlusion is a predisposing factor for Temporomandibular Dysfunctions (TMD) of the joint, whose first sign and/or symptom is usually joint sound. To verify the effect of occlusion on joint sounds, temporomandibular joints (TMJ) were analyzed in 78 asymptomatic individuals with various dental conditions. Electrosonography was used to determine the intensity of the vibration in the temporomandibular joint (TMJ) on opening and closing the mouth. Transducers (piezoelectric accelerometer) were placed on the right and left joints. Results were tabled and analyzed using the Kruskal-Wallis test (a=0.05). It was concluded that TMJ vibration in partly edentulous individuals from Kennedy classes I, II and III is statistically higher than in dentate and fully edentulous subjects.

    Full Text Available Thyroid carcinoma is rare comprising 1% of all malignancies and commonly presents as a neck lump. Papillary thyroid carcinoma unlike follicular thyroid carcinoma tends not to metastasise to distant sites.We present a case of papillary thyroid carcinoma presenting as a solitary asymptomatic pelvic bone metastases and highlight current management of bone metastases. A 59-year old female was found on abdominal computerised tomography to have an incidental finding of a 4.5 cm soft tissue mass in the right iliac bone. Biopsy of the lesion confirmed metastatic thyroid carcinoma. There was no history of a neck lump, head and neck examination was normal. Further imaging confirmed focal activity in the right lobe of the thyroid. A total thyroidectomy and level VI neck dissection was performed and histology confirmed follicular variant of papillary carcinoma.Early detection of bone metastases have been shown to improve prognosis and thyroid carcinoma should be considered as a potential primary malignancy.

    2007-02-01

    X-linked spinal and bulbar muscular atrophy (SBMA or Kennedy's disease) has a variable prognosis. Most male carriers are affected by their fourth or fifth decade of life, while some remain asymptomatic lifelong. Elevations of serum creatine kinase are well known to occur in clinically manifesting SBMA patients. Elevations prior to the onset of the clinical syndrome have not been reported. Here we report two cases of SBMA presenting with 'idiopathic' elevations of serum transaminases and creatine kinase a decade in advance of their symptomatic onset. These cases emphasize the need to consider SBMA and genetic testing for the androgen receptor trinucleotide CAG expansion in males otherwise healthy with 'idiopathic' elevated creatinine kinase.

    Brain check-up was performed in 4000 healthy subjects who underwent medical and radiological examinations for possible brain diseases in our hospital from April 1996 to March 2000. Magnetic resonance imaging revealed 11 brain tumors which consisted of six meningiomas, three pituitary adenomas, one astrocytoma, and one epidermoid cyst. The detection rate of incidental brain tumor in our hospital was 0.3%. Nine patients underwent surgery, with one case of morbidity due to postoperative transient oculomotor nerve paresis. The widespread use of brain check-up may increasingly detect asymptomatic brain tumors. Surgical indications for such lesions remain unclear, and the strategy for treatment should be determined with consideration of the patient's wishes. (author)

    Many papers in the medical literature analyze the cost-effectiveness of screening for diseases by comparing a limited number of a priori testing policies under estimated problem parameters. However, this may be insufficient to determine the best timing of the tests or incorporate changes over time. In this paper, we develop and solve a Markov Decision Process (MDP) model for a simple class of asymptomatic diseases in order to provide the building blocks for analysis of a more general class of diseases. We provide a computationally efficient method for determining a cost-effective dynamic intervention strategy that takes into account (i) the results of the previous test for each individual and (ii) the change in the individual’s behavior based on awareness of the disease. We demonstrate the usefulness of the approach by applying the results to screening decisions for Hepatitis C (HCV) using medical data, and compare our findings to current HCV screening recommendations.

    Full Text Available Bladder leiomyomas are rare benign mesenchymal tumors, which account for less than 0.43% of all bladder tumors with approximately 200 cases described in the literature. These tumors may be classified into 3 different locations: endovesical, intramural and extravesical. Endovesical is the most common form, accounting for 63-86% of the cases, while intramural occurs in 3-7% and extravesical in 11-30%. The intramural form, especially small tumors, may not produce symptoms hardening detection. We report two cases of intramural bladder leiomyomas in asymptomatic men observed incidentally by transabdominal ultrasonography during the follow-up of benign prostatic hyperplasia. We discuss the diagnosis and management of these lesions.

    Full Text Available Abstract Objective Behcet's is an idiopathic multi-organ syndrome, which may have onset during childhood. Vascular involvement is uncommon, with rarely reported coronary aneurysm formation. We present a case report of a teenager girl who developed recalcitrant life-threatening Behcet's vasculitis, involving both small and large venous and arterial systems including a giant coronary aneurysm. Case report De-identified data were collected retrospectively in case report format. Although our sixteen year old female with Behcet's vasculitis had resolution of many arterial aneurysms, she had persistent venous thrombosis of large vessels, as well as persistent, giant arterial aneurysms requiring intra-arterial coiling of a lumbar artery and coronary bypass grafting despite intensive immunosuppression including glucocorticoids, cyclophosphamide, infliximab, methotrexate, azathioprine and intravenous immunoglobulin. Conclusions Vascular manifestations may be seen in Behcet's syndrome, including asymptomatic coronary aneurysm, which may be refractory to immunosuppression and ultimately require surgical intervention. Increased awareness is essential for prompt diagnosis and management.

    A 53-year old previously healthy male underwent a screening colonoscopy for detection of a potential colorectal neoplasm. The terminal ileum was intubated and a mass was noted. Examination of the colon was normal. The biopsy of the ileal mass was consistent with an adenocarcinoma arising from the terminal ileum. His father who had never been previously ill from gastrointestinal disease died of natural causes,but was found to have Crohn's disease postmortem.The patient underwent exploratory laparotomy and aright hemicolectomy with a 30 cm section of terminal ileum in continuity. Findings were consistent with ileal adenocarcinoma in the setting of Crohn's disease. Thepatient made an uneventful recovery. The pathology was stage 1 adenocarcinoma. This is a unique case in that on a screening colonoscopy, a favorable ileal adenocarcinoma was discovered in the setting of asymptomatic, undiagnosed ileal Crohn's disease in a patient whose father had Crohn's disease diagnosed postmortem.

    Full Text Available Cholecystocolonic fistulas (CCF are rare complications of gallstones with a variable clinical presentation. Despite modern diagnostic tools, cholecystocolonic fistulas are often asymptomatic and it is difficult to diagnose them preoperatively. Biliary-enteric fistulae have been found in 0.9% of patients undergoing biliary tract surgery. The most common site of communication of the fistula is the cholecystoduodenal (70%, followed by the cholecystocolic (10–20%, and the least common is the cholecystogastric fistula. Herein, we report a case of female patient with multiple episodes of acute recurrent cholangitis due to common bile duct and gallbladder stones in which preoperative imaging studies were negative for cholecystocolonic fistula that was incidentally discovered and treated during surgery and was appropriately treated. A review of the literature is reported too.

    Background: Because of growing body of interest on the association between fibrosing idiopathic interstitial pneumonias (f-IIP) and ischaemic heart disease, we initiated this prospective study to evaluate the prevalence of asymptomatic coronary artery disease (CAD) in patients with f-IIP. Methods: Forty-two patients with f-IIP underwent noninvasive screening for CAD that included (a) a chest CT examination enabling calculation of the coronary artery calcium (CAC) score, then depiction of coronary artery stenosis; and (b) stress myocardial perfusion scintigraphy (MPS). Patients with significant coronary abnormalities, defined by a CAC score >400 or coronary artery stenosis >50% at CT and/or perfusion defect >5% at MPS, were referred to the cardiologist. Coronary angiography was indicated in presence of a perfusion defect >10% at MPS or significant left main or proximal left anterior descending stenosis whatever MPS findings. Results: Combining CT and MPS, significant abnormalities were detected in 32/42 patients (76%). The cardiologist: (a) did not consider further investigation in 21 patients (CT abnormalities but no ischaemia at MPS: 12/21; false-positive findings at MPS: 3/21; poor respiratory condition: 6/21); (b) proceeded to coronary angiography in 11 patients which confirmed significant stenoses in 5 patients (5/42; 12%). In the worst-case-scenario (i.e., inclusion of 6 patients with significant coronary artery abnormalities who were not investigated due to poor respiratory condition), the prevalence of CAD reached 26% (11/42). Conclusion: In the studied population of patients with f-IIP, asymptomatic CAD ranged between 12% and 26%.

    The aim of this study is to use transthoracic echocardiographic (TTE) imaging methods to identify cardiac dysfunction in asymptomatic systemic lupus erythematosus (SLE) patients and to determine the association between echocardiographic findings and serology. This is a prospective cross-sectional study where 50 patients with confirmed diagnoses of SLE were recruited from rheumatology outpatient clinics. Clinical and serological evaluation to confirm the diagnosis of lupus was done in all patients. Fifty SLE patients, 46 (92%) females and 4 (8%) males, were recruited. Anti-double-stranded DNA (Anti-dsDNA), anticardiolipin, lupus anticoagulant, and anti-β2-glycoproteins were positive in 52.1, 32.6, 13.3, and 15.6%, respectively. Transthoracic echocardiogram revealed mitral regurgitation in 16 patients (32%), pericardial effusion in16 patients (32%), aortic regurgitation in five patients (10%), and tricuspid regurgitation in 10 patients (20%). Eleven patients had left ventricular hypertrophy (22%), and eight patients had ventricular systolic dysfunction (16%). Only four patients had ventricular diastolic dysfunction (8%). A significant association between mitral and tricuspid valve regurgitation and positive anti-dsDNA (p lupus anticoagulant, and anti-β 2 glycoprotein antibodies were also associated with mitral valve regurgitation (p values 0.044, 0.006, and 0.023), respectively. Active disease assessed by Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) was found to be associated with increased risk of mitral valvular leaflet thickening (p value 0.028). Performing regular transthoracic echocardiogram in asymptomatic SLE patients is important for early detection and appropriate treatment of cardiac lesions. Clinically quiescent but serologically active disease and presence of antiphospholipid antibodies were associated with structural heart abnormalities.

    Full Text Available Background/Aim: The objective of this study was to estimate the incidence of the Meckel′s diverticulum (MD and to study its clinical profile and surgical outcome, as well as to check whether diverticulectomy is indicated for asymptomatic MD in adults. Materials and Methods: This is a prospective study of 1332 patients who were operated upon for acute abdomen during the period August 1999 to July 2009 in a single surgical unit. Preoperative abdominal ultrasonography and plain x-ray abdomen (erect were done depending on the necessity. These patients were subjected to laparotomy/ appendicectomy depending on the case. A search for MD was done, and if found, surgical resection and analysis by histopathological confirmation of the resected MD were performed. Results: During the operation, this study detected 15 (1.13% patients with MD. In none of these cases, preoperative diagnosis of Meckel′s diverticulitis was made. The age of the patients ranged from 18 to 68 years (mean age, 32.9 years. Out of 15 patients, 9 (60% were males; 6 (40% were females. Seven (46.7% cases were symptomatic due to MD and 8 (53.3% were asymptomatic. One patient presented with hematochezia; 2, with intestinal obstruction due to gangrene of the MD; and 4, with Meckel′s diverticulitis. One patient had duplication of (double Meckel′s diverticulum without any inflammation in both the diverticulae. Histopathological examination of these specimens confirmed 4 cases with inflammation; 2, with gangrene; and 1, with ulcerated gastric mucosa in the MD. Among these, in 2 (13.3% cases there was heterotopic epithelium (ulcerated gastric mucosa- 1, colonic mucosa- 1. Conclusion: We recommend that a search for MD in every case of appendicectomy/ laparotomy done for acute abdomen should be conducted, and if found, Meckel′s diverticulectomy or resection should be performed to avoid secondary complications arising from it.

    Management guidelines were created to screen and manage asymptomatic renal stones in U.S. astronauts. The true risk for renal stone formation in astronauts due to the space flight environment is unknown. Proper management of this condition is crucial to mitigate health and mission risks. The NASA Flight Medicine Clinic electronic medical record and the Lifetime Surveillance of Astronaut Health databases were reviewed. An extensive review of the literature and current aeromedical standards for the monitoring and management of renal stones was also done. This work was used to develop a screening and management protocol for renal stones in astronauts that is relevant to the spaceflight operational environment. In the proposed guidelines all astronauts receive a yearly screening and post-flight renal ultrasound using a novel ultrasound protocol. The ultrasound protocol uses a combination of factors, including: size, position, shadow, twinkle and dispersion properties to confirm the presence of a renal calcification. For mission-assigned astronauts, any positive ultrasound study is followed by a low-dose renal computed tomography scan and urologic consult. Other specific guidelines were also created. A small asymptomatic renal stone within the renal collecting system may become symptomatic at any time, and therefore affect launch and flight schedules, or cause incapacitation during a mission. Astronauts in need of definitive care can be evacuated from the International Space Station, but for deep space missions evacuation is impossible. The new screening and management algorithm has been implemented and the initial round of screening ultrasounds is under way. Data from these exams will better define the incidence of renal stones in U.S. astronauts, and will be used to inform risk mitigation for both short and long duration spaceflights.

    AIM: To evaluate the prevalence and clinical characteristics of Nonalcoholic fatty liver disease (NAFLD) among asymptomatic Brazilian adolescents.METHODS: Transversal observational study included asymptomatic adolescents with central obesity from private and public schools in Salvador-Bahia, northeastern Brazil. The children answered a questionnaire that included age, gender, race, and medical history, and were submitted to a complete physical exam and abdominal ultrasound. Biochemical exams included: ALT, AST, GGT,C reactive protein (CRP), fasting glucose, insulin, cholesterol and triglycerides. Criteria for NAFLD included: the presence of steatosis in ultrasound and/or high level of ALT, negative or occasional historic of intake of alcohol (≤ 140 g/wk), negative investigation for hepatitis A, B, C,auto-immune hepatitis, Wilson disease and hemochromatosis.RESULTS: From October, 2005 to October, 2006, the study included 1801 subjects between 11 and 18 years of age and a mean age of 13.7±2.0 years.One hundred ninety-nine had central obesity. The prevalence of NAFLD was 2.3%, most of whom were male and white. Insulin resistance (IR) was observed in 22.9% of them and had positive correlations with ALT and GGT ( P < 0.05). Elevated CRP was observed in 6.9% of the cases; however, it was not associated with WC,IR or liver enzymes.CONCLUSION: The prevalence of NAFLD in Brazilian adolescents was low. The ethnicity may have influence this frequency in the population studied, which had a large proportion of African descendents.

    Clostridium difficile is well recognized as the common pathogen of nosocomial diarrhea, meanwhile, asymptomatic colonization with C. difficile in part of the population has also drawn public attention. Although gut microbiota is known to play an important role in the pathogenesis of C. difficile infection (CDI), whether there is any alteration of gut microbial composition in asymptomatic C. difficile carriers hasn't been clearly described. The purpose of this study was to explore the differences in gut microbiome among CDI patients, asymptomatic C. difficile carriers and healthy individuals. We performed fecal microbiota analysis on the samples of eight CDI patients, eight asymptomatic C. difficile carriers and nine healthy subjects using 16S rRNA gene pyrosequencing. CDI patients and asymptomatic carriers showed reduced microbial richness and diversity compared with healthy subjects, accompanied with a paucity of phylum Bacteroidetes and Firmicutes as well as an overabundance of Proteobacteria. Some normally commensal bacteria, especially butyrate producers, were significantly depleted in CDI patients and asymptomatic carriers. Furthermore, the differences observed in microbial community structure between CDI patients and asymptomatic carriers suggested that the gut microbiota may be a potential factor of disease state for CDI. Our study demonstrates the characterization and diversity of gut microbiota in CDI and asymptomatic C. difficile colonization, which will provide new ideas for surveillance of the disease state and development of microbiota-targeted agents for CDI prevention and treatment.

    Full Text Available A malaria survey was conducted in an area of high transmission (Costa Marques, Rondonia, Brazil to determine the prevalence of asymptomatic parasitemia and its clinical significance. Most of the people surveyed were immigrants who had lived in the endemic area 2 days, 4 had only gametocytes, 1 had taken inadequate anti-malarial treatment, 3 were under treatment and 2 moved. Six asymptomatic patients denied the use of anti-malarial drugs and they developed malaria 3-6 days after the initial parasitological diagnosis. The final patient remained asymptomatic during the 7 day observation period. He had a history of > 40 malaria attacks and denied the use of antimalarial treatment. With the exception of the latter all of the other asymptomatic patients, were either in the incubation period or had been treated It is concluded that asymptomatic malaria is rare in the Costa Marques area and that it is necessary to treat all individuals with plasmodial parasitemia.

    Full Text Available Multiple lymphomatous polyposis (MLP as an extranodal manifestation of mantle cell lymphoma (MCL in the gastrointestinal tract is rare and not often reported in the literature. We describe the case of a 63-year-old female with asymptomatic MLP found during staging bidirectional endoscopy of MCL. The patient presented only with dyspnea, but was found on physical exam to have diffuse lymphadenopathy, and subsequent positron emission tomography (PET CT showed extensive lymph node adenopathy consistent with lymphoma. Excisional lymph node biopsy revealed high-risk MCL. Prior to therapy, staging bidirectional endoscopy was performed, which revealed duodenal bulb polyps and diffuse polyposis in the colon. Biopsies showed atypical lymphoid infiltrate identical to the initial excisional lymph node biopsy. The patient underwent aggressive induction therapy, chemotherapy and bone marrow transplantation. Four months later, repeat colonoscopy and biopsies showed normal mucosa, and repeat PET CT showed no evidence of systemic disease. Eight months later, the patient began having symptoms consistent with cauda equina syndrome, and she was found to have leptomeningeal recurrence of MCL. In spite of other medical treatment, the patient’s MCL progressed and she passed away 3 years after the initial presentation.

    Full Text Available A quantitative real time polymerase chain reaction (PCR revealed canine distemper virus presence in peripheral blood samples from asymptomatic and non vaccinated dogs. Samples from eleven domestic dogs with no signs of canine distemper and not vaccinated at the month of collection were used. Canine distemper virus vaccine samples in VERO cells were used as positive controls. RNA was isolated with Trizol®, and treated with a TURBO DNA-free kit. Primers were designed for canine distemper virus nucleocapsid protein coding region fragment amplification (84 bp. Canine b-actin (93 bp was utilized as the endogenous control for normalization. Quantitative results of real time PCR generated by ABI Prism 7000 SDS Software showed that 54.5% of dogs with asymptomatic canine distemper were positive for canine distemper virus. Dissociation curves confirmed the specificity of the real time PCR fragments. This technique could detect even a few copies of viral RNA and identificate subclinically infected dogs providing accurate diagnosis of this disease at an early stage.A reação em cadeia da polimerase (PCR em tempo real revelou a presença do vírus da cinomose canina em amostra de sangue de cães assintomáticos e não vacinados.

    K Abigail Andrews

    Full Text Available There is considerable interest in designing therapeutic studies of individuals at risk of Alzheimer disease (AD to prevent the onset of symptoms. Cortical β-amyloid plaques, the first stage of AD pathology, can be detected in vivo using positron emission tomography (PET, and several studies have shown that ~1/3 of healthy elderly have significant β-amyloid deposition. Here we assessed whether asymptomatic amyloid-PET-positive controls have increased rates of brain atrophy, which could be harnessed as an outcome measure for AD prevention trials. We assessed 66 control subjects (age = 73.5±7.3 yrs; MMSE = 29±1.3 from the Australian Imaging Biomarkers & Lifestyle study who had a baseline Pittsburgh Compound B (PiB PET scan and two 3T MRI scans ~18-months apart. We calculated PET standard uptake value ratios (SUVR, and classified individuals as amyloid-positive/negative. Baseline and 18-month MRI scans were registered, and brain, hippocampal, and ventricular volumes and annualized volume changes calculated. Increasing baseline PiB-PET measures of β-amyloid load correlated with hippocampal atrophy rate independent of age (p = 0.014. Twenty-two (1/3 were PiB-positive (SUVR>1.40, the remaining 44 PiB-negative (SUVR≤1.31. Compared to PiB-negatives, PiB-positive individuals were older (76.8±7.5 vs. 71.7±7.5, p<0.05 and more were APOE4 positive (63.6% vs. 19.2%, p<0.01 but there were no differences in baseline brain, ventricle or hippocampal volumes, either with or without correction for total intracranial volume, once age and gender were accounted for. The PiB-positive group had greater total hippocampal loss (0.06±0.08 vs. 0.02±0.05 ml/yr, p = 0.02, independent of age and gender, with non-significantly higher rates of whole brain (7.1±9.4 vs. 4.7±5.5 ml/yr and ventricular (2.0±3.0 vs. 1.1±1.0 ml/yr change. Based on the observed effect size, recruiting 384 (95%CI 195-1080 amyloid-positive subjects/arm will provide 80% power to detect 25

    Objective: While HIV-associated neurocognitive disorders (HAND) remain prevalent despite combination antiretroviral therapy (CART), the clinical relevance of asymptomatic neurocognitive impairment (ANI), the most common HAND diagnosis, remains unclear. We investigated whether HIV-infected persons with ANI were more likely than those who were neurocognitively normal (NCN) to experience a decline in everyday functioning (symptomatic decline). Methods: A total of 347 human participants from the CNS HIV Anti-Retroviral Therapy Effects Research (CHARTER) cohort were NCN (n = 226) or had ANI (n = 121) at baseline. Neurocognitive assessments occurred approximately every 6 months, with median (interquartile range) follow-up of 45.2 (28.7–63.7) months. Symptomatic decline was based on self-report (SR) or objective, performance-based (PB) problems in everyday functioning. Proportional hazards modeling was used to generate risk ratios for progression to symptomatic HAND after adjusting for baseline and time-dependent covariates, including CD4+ T-lymphocyte count (CD4), virologic suppression, CART, and mood. Results: The ANI group had a shorter time to symptomatic HAND than the NCN after adjusting for baseline predictors: adjusted risk ratios for symptomatic HAND were 2.0 (confidence interval [CI] 1.1–3.6; p = 0.02) for SR, 5.8 (CI 3.2–10.7; p < 0.0001) for PB, and 3.2 (CI 2.0–5.0; p < 0.0001) for either SR or PB. Current CD4 and depression were significant time-dependent covariates, but antiretroviral regimen, virologic suppression, and substance abuse or dependence were not. Conclusions: This longitudinal study demonstrates that ANI conveys a 2-fold to 6-fold increase in risk for earlier development of symptomatic HAND, supporting the prognostic value of the ANI diagnosis in clinical settings. Identifying those at highest risk for symptomatic decline may offer an opportunity to modify treatment to delay progression. PMID:24814848

    Gluten-containing cereals are a main food staple present in the daily human diet, including wheat, barley, and rye. Gluten intake is associated with the development of celiac disease (CD) and related disorders such as diabetes mellitus type I, depression, and schizophrenia. However, until now, there is no consent about the possible deleterious effects of gluten intake because of often failing symptoms even in persons with proven CD. Asymptomatic CD (ACD) is present in the majority of affected patients and is characterized by the absence of classical gluten-intolerance signs, such as diarrhea, bloating, and abdominal pain. Nevertheless, these individuals very often develop diseases that can be related with gluten intake. Gluten can be degraded into several morphine-like substances, named gluten exorphins. These compounds have proven opioid effects and could mask the deleterious effects of gluten protein on gastrointestinal lining and function. Here we describe a putative mechanism, explaining how gluten could "mask" its own toxicity by exorphins that are produced through gluten protein digestion.

    Objective. To determine the postoperative appearance of the plantar fascia on MR imaging after a fasciotomy has been performed, and to compare the postsurgical appearance of the fascia after an open and endoscopic procedure.< rate at head-abs-p1.lf>Design and patients. Fifteen asymptomatic volunteers (12 women, 3 men; age range 22-49 years, mean age 33 years) with prior fasciotomies for treatment of longstanding plantar fasciitis were studied. Fourteen volunteers had a unilateral release and one volunteer had bilateral releases, allowing for assessment of 16 ankles. Eight fasciotomies were performed through an open incision and eight were performed endoscopically. The average time between surgery and imaging was 24 months (range 11-46 months). The site of surgery was established from the operative reports. Proton density (PD)-weighted and T2-weighted images in three orthogonal planes were obtained on a 1.5-T magnet. In eight studies, T1-weighted sagittal and STIR sagittal images were included. The fascia in each ankle was assessed for morphology and signal intensity. Perifascial soft tissues and bone marrow were assessed for edema. Preoperative MR studies were available in five volunteers.< rate at head-abs-p1.lf>Results. There was no apparent difference in the postoperative appearance of the ankle after an open or endoscopic procedure except for scar formation in the subcutaneous fat which was common after an open procedure (P<0.05). Three ankles had a gap in the fascia (one open, two endoscopic). The plantar fascia measured a mean of 7.0 mm (range 5-10 mm) at the fasciotomy, and 8.3 mm (range 6-12 mm) at the enthesis. At the fasciotomy, 11 of 13 ankles had an indistinct deep contour and 9 of 13 had an indistinct superficial contour. At the enthesis, 13 of 16 ankles had an indistinct deep contour and 6 of 16 had an indistinct superficial contour. Compared with preoperative MR studies there was an average reduction in the fascial thickness at the enthesis of 14

    AIM: Primary biliary cirrhosis (PBC) is a chronic, cholestatic disease of autoimmune etiology, the histology of which shows a destruction of the intrahepatic bile duct and portal inflammation. Ursodeoxycholic acid (UDCA) is now used as a first-line drug for asymptomatic PBC (aPBC) because it is reported that UDCA decreases mortality and prolongs the time of liver transplantation. However, only 20-30% of patients respond fully to UDCA. Recently, lipoproteinlowering agents have been found to be effective for PBC. The aim of this study was to examine the safety and efficacy of fenofibrate, a member of the fibrate class of hypolipidemic and anti-inflammatory agent via peroxysome proliferatory activated receptor α, in patients with aPBC. METHODS: Fenofibrate was administered for twelve weeks in nine patients with aPBC who failed to respond to UDCA. UDCA was used along with fenofibrate during the study. The data from aPBC patients were analyzed to assess the biochemical effect of fenofibrate during the study. RESULTS: The serum levels of alkaline phosphatase (ALP) (285±114.8 IU/L) and immunoglobulin M (IgM) (255.8±85.9 mg/dl) significantly decreased to 186.9±76.2 IU/L and 192.9±67.5 mg/dL respectively, after fenofibrate treatment in patients with aPBC (P<0.05). Moreover, the titer of antimitochondrial antibody (AMA) also decreased in 4 of 9 patients with aPBC. No adverse reactions were observed in any patients.CONCLUSION: Fenofibrate appears to be significantly effective in treating patients with aPBC who respond incompletely to UDCA alone. Although the mechanism of fenofibrate on aPBC has not yet been fully clarified, combination therapy using fenofibrate and UDCA might be related to the anti-immunological effects, such as the suppression of AMA production as well as its anti inflammatory effect.

    Full Text Available As human life expectancy continues to increase, developing countries are reporting higher percentages of elderly in their respective populations. The defense mechanisms of the elderly are reduced due to several factors, such as increased susceptibility to infection, specifically urinary tract infection (UTI. A randomised, placebo-controlled, double-blind trial was conducted to assess whether multimicronutrient supplementation is effective in reducing UTIs in older people in the community. A total of 261 elderly who lived in Mampang Prapatan district, South Jakarta, were randomised to daily multimicronutrient supplementation or control groups. The primary outcomes were the incidence of asymptomatic UTI, the organisms responsible for UTIs and the results of sensitivity tests on UTI microorganisms. UTI was defined as culture-positive urine yielding a single species of organisms in numbers greater than 104 cfu/mL urine specimen. At base-line 19.5% of the elderly had UTI, namely 23.7% patients in the MMN group and 16.7% in the control group, but the difference was not statistically significant (p=0.158. Escherichia coli was the most common microorganism, isolated in 20.7% of the MMN group and 17.5% of the control group. After six months of supplementation, UTI in the MMN group decreased by 40.6% compared with only 14.4% in the control group. The numbers of E. coli also declined by 64.3% in the MMN group compared to 37.8% in the control group. This study has confirmed the beneficial effect of multimicronutrient supplementation on UTI in the elderly.

    Some authors claim that occlusal appliances can enhance athletic performance. Therefore, this study investigated the influence of dental occlusion on knee muscle strength performance. Twelve healthy female subjects (mean age, 24.1 ± 3.1 years) without temporomandibular joint dysfunction participated in this study. Isokinetic quadriceps and hamstring strength were assessed in relation to 3 randomized jaw conditions: mouth closed in maximum intercuspidation without splint, mouth closed on a balanced splint which optimized contact over the dental arch, mouth closed on a piece of resin of 1 mm which created an imbalanced occlusion. Tests were performed at 60 and 240°·s in concentric and 30°·s in eccentric exertions. Concentric performances did not show any significant difference between the 3 jaw conditions (p > 0.05). In contrast, in the eccentric trials related to quadriceps performance, significant differences (p ≤ 0.05) were observed between the resin condition and the 2 other modalities (without splint or with a balanced splint). The imbalanced occlusion created by the resin component corresponded to an average decrease of 9% in eccentric peak torque. The eccentric hamstring peak torques also showed a significant difference (p ≤ 0.05) between measurements with splint and with resin (7% decrease when occlusion was imbalanced). In conclusion, among asymptomatic females, artificial imbalanced occlusion induces immediate and significant alteration of knee eccentric muscle performances. Therefore, occlusion examination should be undertaken on a regular and frequent basis for high-level athletes. Moreover, for athletes using mouthguards, muscular performance assessments should be planned with and without the dental protection.

    Intradialytic hypotension (IDH) remains an important cause of morbidity and mortality in chronic hemodialysis (HD) patients and can be ameliorated by cool temperature HD. The baroreflex arc is under autonomic control and is essential in the short-term regulation of blood pressure (BP). This study aimed to investigate if the baroreflex sensitivity (BRS) response to HD differed between standard and cool-temperature dialysate. Ten patients (mean age 67+/-2 years) prone to IDH were recruited into a randomized, crossover study to compare BRS variation at dialysate temperatures of 37 degrees C (HD(37)) and 35 degrees C (HD(35)). Each patient underwent continuous beat-to-beat BP monitoring during a dialysis session of HD(37) and HD(35). During HD(37) 2 patients developed symptomatic IDH, as opposed to 1 with HD(35). However, asymptomatic IDH occurred with a frequency of 0.4 episodes per session with HD(35) and 6.2 episodes per session during HD(37) (odds ratio15.5; 95%CI 5.6-14.2). Although absolute BRS measurements did not differ between the 2 modalities, BRS variability increased during HD(35). Our study has demonstrated that in IDH-prone patients, cool HD resulted in a reduction in heart rate and a greater reduction in cardiac output and stroke volume. Mean arterial pressure was maintained through a significantly greater increase in total peripheral resistance. Furthermore, although absolute BRS values during HD were not significantly altered by a reduction in dialysate temperature, there was a greater percentage increase in BRS values during cool HD. Understanding the varied causes of, and categorizing impaired hemodynamic responses to HD will enable further individualization of HD prescriptions according to patient need.

    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.

    Abstract The aim of this study was to evaluate sex difference in the prevalence and risk factors for asymptomatic cholelithiasis in Korean health screening examinees. Examinees who underwent examination through health promotion center at 5 hospitals of Daegu-Gyeongbuk province in 2014 were analyzed retrospectively. All examinees were checked for height, weight, waist circumference, and blood pressure, and underwent laboratory tests and abdominal ultrasound. Diagnosis of cholelithiasis was made by ultrasound. Of the total of 30,544 examinees, mean age was 47.3 ± 10.9 years and male to female ratio was 1.4:1. Asymptomatic cholelithiasis was diagnosed in 1268 examinees with overall prevalence of 4.2%. In age below 40 years, females showed higher prevalence of asymptomatic cholelithiasis than males (2.7% vs. 1.9%, P = 0.020), whereas prevalence of asymptomatic cholelithiasis was higher in males than females older than 50 years (6.2% vs. 5.1%, P = 0.012). Multiple logistic regression analysis revealed age (≥50 years), obesity, and high blood pressure as risk factors for asymptomatic cholelithiasis in males and age, obesity, hypertriglyceridemia, and chronic hepatitis B infection in females (P < 0.05). Overall prevalence of asymptomatic cholelithiasis was 4.2% in Korean health screening examinees. Females showed higher prevalence of asymptomatic cholelithiasis than males younger than 40 years, whereas it was higher in males older than 50 years. Age and obesity were risk factors for asymptomatic cholelithiasis in both sexes. Males had additional risk factors of high blood pressure and females had hypertriglyceridemia and chronic hepatitis B infection. PMID:28353587

    Background Percutaneous coronary intervention (PCI) is indicated for angina with coronary stenosis.However,PCI for asymptomatic coronary stenosis remains controversial.We prospectively followed a group of patients for four years who underwent coronary computed tomography angiography (CCTA) for major adverse cardiac events (MACE).We hypothesized that the results of this trial would reliably reflect the natural outcome of the coronary disease.Methods Consecutive patients who underwent CCTA from June 2008 to May 2009 were selected.Those who could not be reached by telephone,had significant angina,had CT images that were not interpretable,or poor kidney and left ventricular (LV) function were excluded.The patients were divided into five groups:group A normal CCTA without stenosis,group B mild stenosis (1%-49%),group C moderate stenosis (50%-74%),group D severe stenosis (≥75%) and they were treated with optimal medical therapy (OMT) or PCI.The group E had PCI before the CCTA examination.The patients were then followed for MACE after different treatments.MACE included acute myocardial infarction (MI),heart failure (HF) and death.Results The patient population consisted of 419 patients.The follow-up time was (51±5) months.The age was (60±31)years.Male made up 67.78% of the population (n=284).A total of 51 cases of MACE occurred including 25 MI,eight HF and 18 all-cause deaths.There was no MACE in group A.Although MACE occurred in two patients in group B,they were not attributed to cardiac death.We further compared the MACE in groups C-E and no significant difference was found (P >0.05).However,a difference was detected among patients with unstable angina pectoris (UAP),stable angina pectoris (SAP),re-hospitalization,and cerebrovascular events from groups A-E (P <0.05).The plaque scores were used to predict MACE.The scores progressively increased significantly with lesion severity (P <0.05).Receiver operating curve (ROC) was performed to determine the

    Full Text Available Background & objectives: In malaria endemic areas, continuous exposure to Plasmodium parasites leads to asymptomatic carriers that provide a reservoir, contributing to the persistence of malaria transmission. Thus, a study of the degree of prevalence of asymptomatic parasitaemias will help in assessing the level of reservoir of infection. Methods: All the consented participants without any signs and symptoms, suggestive of malaria were interviewed and thick blood smears were made to detect malaria parasites. The children presenting with malaria or any other severe illness, and those declining to give consent were excluded from the study. Results: A total of 118 (59.6% children out of 198 apparently healthy children were positive for malaria parasites while 80 (40.4% children were negative for malaria parasites. Prevalence of asymptomatic malaria was higher in males 75 (63.6% compared to females 43 (36.4%, but the difference was not statistically significant. Incidence of asymptomatic malaria was highest with 76.1% in the children aged 6– 10 yr. There was statistically significant association of the use of bednet on prevalence of asymptomatic malaria. Interpretation & conclusion: High prevalence of asymptomatic malaria detected in this study is a big challenge and can be a threat to the present malaria control programme. Thus, it should be considered in assessing and reorganising more effective malaria elimination strategies to achieve the desired goal of malaria control.

    Neurocysticercosis (NCC) is the most frequent parasitic infection of the central nervous system caused by the larvae of Taenia solium. The prevalence of NCC is obscured due to variations in the methods used for epidemiological studies and often asymptomatic manifestation. The present study was conducted on 595 apparently healthy individuals belonging to the pig farming community of northern India to estimate the prevalence of asymptomatic NCC and to evaluate risk factors based on questionnaires. Diagnosis of NCC was based on neuroimaging, immunological and epidemiological criteria. Asymptomatic NCC was detected in 90 (15.1%) of 595 individuals. The evaluation of risk factors showed that age >15 years (P=0.001), intake of raw vegetables (P=0.025) and undercooked pork (P=0.005), lack of safe drinking water (P=0.003), inadequate drainage system (P=0.049), no separate place for pigs (P≤0.001), NCC related active epilepsy in the family (P≤0.001) were significantly associated with asymptomatic NCC. The present study shows high prevalence of asymptomatic NCC in pig farming community of northern India. Further, asymptomatic NCC is associated with most variables of poor socio-economic parameters.

    Full Text Available Stroke remains an exceedingly incident and prevalent public health burden across the globe, with an estimated 16 million new strokes per annum and prevalence over 60 million, and extracranial internal carotid artery atherosclerotic disease is an important risk factor for stroke. Randomized trials of surgical treatment were conducted (North American Symptomatic Carotid Endarterectomy Trial, European Carotid Surgery Trial and demonstrated efficacy of carotid endarterectomy for secondary prevention of stroke in patients with cerebrovascular events (e.g. ipsilateral stroke, transient ischemic attack, and/or amaurosis fugax attributable to a diseased artery with 50–99% stenosis. Therapeutic clarity, however, proved elusive with asymptomatic carotid artery disease. Asymptomatic Carotid Atherosclerosis Study (ACAS, Asymptomatic Carotid Surgery Trial, and Veterans Affairs Cooperative Study (VACS suggested only modest benefit from surgical intervention for primary stroke prevention and the best medical therapy at the time of these trials is not comparable to modern medical therapy. ACT-1, Asymptomatic Carotid Surgery Trial-2, Stent-Protected Angioplasty in asymptomatic Carotid artery stenosis versus Endarterectomy Trial-2, European Carotid Surgery Trial-2, Carotid Revascularization Endarterectomy Versus Stenting Trial-2 are trials that are recent, ongoing, or in development that include diverse populations across Europe and North America, complementary trial designs, and a collaborative spirit that should provide clinicians with evidence that informs best clinical practice for asymptomatic carotid artery disease.

    Streptococcus agalactiae causes both symptomatic cystitis and asymptomatic bacteriuria (ABU); however, growth characteristics of S. agalactiae in human urine have not previously been reported. Here, we describe a phenotype of robust growth in human urine observed in ABU-causing S. agalactiae (ABSA) that was not seen among uropathogenic S. agalactiae (UPSA) strains isolated from patients with acute cystitis. In direct competition assays using pooled human urine inoculated with equal numbers of a prototype ABSA strain, designated ABSA 1014, and any one of several UPSA strains, measurement of the percentage of each strain recovered over time showed a markedly superior fitness of ABSA 1014 for urine growth. Comparative phenotype profiling of ABSA 1014 and UPSA strain 807, isolated from a patient with acute cystitis, using metabolic arrays of >2,500 substrates and conditions revealed unique and specific l-malic acid catabolism in ABSA 1014 that was absent in UPSA 807. Whole-genome sequencing also revealed divergence in malic enzyme-encoding genes between the strains predicted to impact the activity of the malate metabolic pathway. Comparative growth assays in urine comparing wild-type ABSA and gene-deficient mutants that were functionally inactivated for the malic enzyme metabolic pathway by targeted disruption of the maeE or maeK gene in ABSA demonstrated attenuated growth of the mutants in normal human urine as well as synthetic human urine containing malic acid. We conclude that some S. agalactiae strains can grow in human urine, and this relates in part to malic acid metabolism, which may affect the persistence or progression of S. agalactiae ABU.

    AIM: To investigate the prevalence of advanced polyps in asymptomatic Chinese and to determine the risk of proximal advanced colonic polyps in subjects with and without polyps in the distal colon.METHODS: Data were collected prospectively during colonoscopic examinations performed in 5 973 subjects as part of health evaluation at our unit from December 1997 to December 2003. Polyps were considered advanced, if they were larger than 10 mm or were tubovillous, villous or malignant. Proximal colon was defined as the splenic flexure and more proximal portions of the colon.RESULTS: Colon polyps were detected in 971 (16.3%)subjects (613 males and 358 females) with their mean age being 56.6±10.7 years. Advanced polyps were noted in 199 (3.3%) individuals. Subjects were sub-classified according to the location of polyps into three groups: distal (569, 58.6%), proximal (284, 29.2%), and combined proximal and distal (118, 12.2%) groups. Subjects with advanced polyps in these three groups were 95 (9.8%),56 (5.8%), and 48 (4.9%) respectively. In the 48 subjects with advanced combined polyps, 13 advanced polyps were distributed at the distal colon, 17 at the proximal colon,and 18 at both. Eighteen colon cancers including 12 at sigmoid and 6 at ascending colon were confirmed by final pathology. The relative risk for advanced proximal polyp according to distal findings was 3.1 (95%CI: 1.3-7.4) for hyperplastic polyp, 2.7 (95%CI: 1.4-5.3) for tubular polyp and 13.5 (95%CI: 5.1-35.4) for advanced polyp as compared to that for no polyp. However, 56 (28.2%) of 199 subjects with advanced polyps had no index polyps at the distal colon and might go undetected under sigmoidoscopic screening.CONCLUSION: Although distal lesions can predict the risk of advanced proximal polyps, a substantial portion of Chinese with advanced proximal polyps is not associated with any distal sentinel lesions. These data have implications for screening policy of colon cancers in Taiwanese Chinese.

    The aim of this work is to use quantitative magnetic resonance imaging (MRI) to identify patients at risk for symptomatic osteoarthritis (OA) progression. We hypothesized that classification of signal variation on T2 maps might predict symptomatic OA progression. Patients were selected from the Osteoarthritis Initiative (OAI), a prospective cohort. Two groups were identified: a symptomatic OA progression group and a control group. At baseline, both groups were asymptomatic (Western Ontario and McMaster Universities Arthritis [WOMAC] pain score total <10) with no radiographic evidence of OA (Kellgren-Lawrence [KL] score ≤ 1). The OA progression group (n = 103) had a change in total WOMAC score greater than 10 by the 3-year follow-up. The control group (n = 79) remained asymptomatic, with a change in total WOMAC score less than 10 at the 3-year follow-up. A classifier was designed to predict OA progression in an independent population based on T2 map cartilage signal variation. The classifier was designed using a nearest neighbor classification based on a Gaussian Mixture Model log-likelihood fit of T2 map cartilage voxel intensities. The use of T2 map signal variation to predict symptomatic OA progression in asymptomatic individuals achieved a specificity of 89.3 %, a sensitivity of 77.2 %, and an overall accuracy rate of 84.2 %. T2 map signal variation can predict symptomatic knee OA progression in asymptomatic individuals, serving as a possible early OA imaging biomarker. (orig.)

    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

    PURPOSE: To search for anti-retina antibodies that serve as markers for eye disease in uveitis. MATERIALS AND METHODS: Stored sera from patients with uveitis, ocular toxoplasmosis (n = 30) and non-infectious, immune-mediated uveitis (n = 50) and from asymptomatic individuals who were positive (n = 250) and negative (n = 250) for anti-Toxoplasma antibodies were tested. Serum anti-retina IgG was detected by an optimized ELISA using a solid-phase whole human retina extract, bovine S-antigen or interphotoreceptor retinoid-binding protein. RESULTS: Uveitis patients showed a higher mean reactivity to whole human retina extract, interphotoreceptor retinoid-binding protein and S-antigen in comparison to the asymptomatic population. These findings were independent of the uveitis origin and allowed the determination of the lower anti-retina antibody cut-off for the three antigens. Asymptomatic anti-Toxoplasma serum-positive individuals showed a higher frequency of anti-human whole retina extract antibodies in comparison to asymptomatic anti-Toxoplasma serum-negative patients. The bovine S-antigen and interphotoreceptor retinoid-binding protein ELISAs also showed a higher mean reactivity in the uveitis groups compared to the asymptomatic group, but the observed reactivities were lower and overlapped without discrimination. CONCLUSION: We detected higher levels of anti-retina antibodies in uveitis patients and in a small fraction of asymptomatic patients with chronic toxoplasmosis. The presence of anti-retina antibodies in sera might be a marker of eye disease in asymptomatic patients, especially when whole human retina extract is used in a solid-phase ELISA. PMID:21120306

    AIM: To investigate the prevalence and risk factors of asymptomatic peptic ulcer disease (PUD) in a general Taiwanese population. METHODS: From January to August 2008, consecu-tive asymptomatic subjects undergoing a routine health check-up were evaluated by upper gastrointestinal en-doscopy. Gastroduodenal mucosal breaks were carefully assessed, and a complete medical history and demo-graphic data were obtained from each patient. Logistic regression analysis was conducted to identify indepen-dent risk factors for asymptomatic PUD. RESULTS: Of the 572 asymptomatic subjects, 54 (9.4%) were diagnosed as having PUD. The prevalence of gas-tric ulcer, duodenal ulcer and both gastric and duode-nal ulcers were 4.7%, 3.9%, and 0.9%, respectively. Multivariate analysis revealed that prior history of PUD [odds ratio (OR), 2.0, 95% CI: 1.3-2.9], high body mass index [body mass index (BMI) 25-30: OR, 1.5, 95% CI: 1.0-2.2; BMI > 30 kg/m2: OR, 3.6, 95% CI: 1.5-8.7] and current smoker (OR, 2.6, 95% CI: 1.6-4.4) were in-dependent predictors of asymptomatic PUD. In contrast, high education level was a negative predictor of PUD (years of education 10-12: OR, 0.5, 95% CI: 0.3-0.8; years of education > 12: OR, 0.6, 95% CI: 0.3-0.9).CONCLUSION: The prevalence of PUD in asymptom-atic subjects is 9.4% in Taiwan. Prior history of PUD, low education level, a high BMI and current smoker are independent risk factors for developing asymptomatic PUD.

    Human rhinovirus (HRV) infections are common but poorly characterized in university students. Thus, we characterized asymptomatic and symptomatic HRV infections by incidence, species diversity, and viral load of 502 university students during September and October of 2010 and 2011 from nasal swabs and electronically submitted symptom questionnaires. We tested all symptomatic students and randomly sampled participants who remained asymptomatic (n=25/week, over 8 weeks each study year) on a weekly basis by real-time PCR and sequenced HRV positives. HRV was identified in 33/400 (8.3%) and 85/92 (92.4%) of the asymptomatic and symptomatic students, respectively. We identified a higher than previously reported rate of HRV-B in both groups, although the distribution of HRV species was similar (P=0.37). Asymptomatic viral load averaged 1.2 log10 copies/mL lower than symptomatic HRV (P<0.001). In conclusion, asymptomatic HRV activity preceded peak symptomatic activity in September and October and was associated with lower viral load.

    Dengue virus infection is a common tropical disease which often occurs without being detected. These asymptomatic cases provide information in relation to the manifestation of immunological aspects. In this study, we developed an ELISA method to compare neutralizing effects of dengue prM and E antibodies between dengue patients and their asymptomatic household members. Recombinant D2 premembrane (prM) was constructed, cloned, and tested for antigenicity. The recombinant protein was purified and tested with controls by using an indirect ELISA method. Positive dengue serum samples with their asymptomatic pair were then carried out onto the developed ELISA. In addition, commercially available recombinant envelope (E) protein was used to develop an ELISA which was tested with the same set of serum samples in the prM ELISA. Asymptomatic individuals showed preexisting heterotypic neutralizing antibodies. The recombinant prM was antigenically reactive in the developed ELISA. Dengue patients had higher prM and E antibodies compared to their household members. Our study highlights the neutralizing antibodies levels with respect to dengue prM and E between dengue patients and asymptomatic individuals.

    Temporal cortex abnormalities are common in patients with mesial temporal lobe epilepsy due to hippocampal sclerosis (MTLE+HS) and believed to be relevant to the underlying mechanisms. In the present study, we set out to determine the familiarity of temporal cortex morphologic alterations in a cohort of MTLE+HS patients and their asymptomatic siblings. A surface-based morphometry (SBM) method was applied to process MRI data acquired from 140 individuals (50 patients with unilateral MTLE+HS, 50 asymptomatic siblings of patients, and 40 healthy controls). Using a region-of-interest approach, alterations in temporal cortex morphology were determined in patients and their asymptomatic siblings by comparing with the controls. Alterations in temporal cortex morphology were identified in MTLE+HS patients ipsilaterally within the anterio-medial regions, including the entorhinal cortex, parahippocampal gyrus, and temporal pole. Subtle but similar pattern of morphology changes with a medium effect size were also noted in the asymptomatic siblings. These localized alterations were related to volume loss that appeared driven by shared contractions in cerebral cortex surface area. These findings indicate that temporal cortex morphologic alterations are common to patients and their asymptomatic siblings and suggest that such localized traits are possibly heritable.

    To make normative width measurements of the ischiofemoral (IF) space in an asymptomatic population and to record soft tissue MRI signal variations within the IF space in order to determine whether such variations are associated with IF space dimensions. Normative width measurements of the IF space were prospectively made in 418 hips on 1.5 T MR images of 209 asymptomatic volunteers. Quantitative and qualitative assessments of the IF soft tissues including the quadratus femoris (QF) muscle were also made. The mean IF space width was 2.56 ± 0.75 cm (right, 2.60 ± 0.75 cm; left, 2.53 ± 0.75 cm). Soft tissue MRI signal abnormalities were present within the IF space in 19 (9.1 %) of 209 volunteers. Soft tissue abnormalities within the IF space included oedema (3/209, 1.4 %) of the QF and/or surrounding soft tissue, and only fatty infiltration (16/209, 7.7 %) of the QF. Bilateral IF spaces are asymmetrical in asymptomatic persons. There is ≥10 % of width difference between right and left IF spaces in approximately half of asymptomatic individuals. Fatty infiltration and oedema can be present at the IF space in a small portion of the asymptomatic population, who also have narrower IF spaces than those without soft tissue MRI signal abnormalities.

    To identify asymptomatic patients is the challenging task and the essential first step in diagnosis. Findings of dental panoramic radiographs include not only dental conditions but also radiographic signs that are suggestive of possible systemic diseases such as osteoporosis, arteriosclerosis, and maxillary sinusitis. Detection of such signs on panoramic radiographs has a potential to provide supplemental benefits for patients. However, it is not easy for general dental practitioners to pay careful attention to such signs. We addressed the development of a computer-aided detection (CAD) system that detects radiographic signs of pathology on panoramic images, and the design of the framework of new screening pathway by cooperation of dentists and our CAD system. The performance evaluation of our CAD system showed the sensitivity and specificity in the identification of osteoporotic patients were 92.6 % and 100 %, respectively, and those of the maxillary sinus abnormality were 89.6 % and 73.6 %, respectively. The detection rate of carotid artery calcifications that suggests the need for further medical evaluation was approximately 93.6 % with 4.4 false-positives per image. To validate the utility of the new screening pathway, preliminary clinical trials by using our CAD system were conducted. To date, 223 panoramic images were processed and 4 asymptomatic patients with suspected osteoporosis, 7 asymptomatic patients with suspected calcifications, and 40 asymptomatic patients with suspected maxillary sinusitis were detected in our initial trial. It was suggested that our new screening pathway could be useful to identify asymptomatic patients with systemic diseases.

    Full Text Available Sub-Saharan Africa records each year about thirty-two million pregnant women living in areas of high transmission of Plasmodium falciparum causing malaria. The aim of this study was to carve out the prevalence of asymptomatic malaria among pregnant women and to emphasize its influence on haematological markers. The prevalence of Plasmodium falciparum asymptomatic infection among pregnant women was 30% and 24% with rapid detection test (RDT and microscopy, respectively. The prevalence of P. falciparum asymptomatic malaria was reduced among pregnant women using sulfadoxine-pyrimethamine's intermittent preventive treatment and 61% of them were anaemic. Anaemia was significantly more common in women infected with P. falciparum compared with the uninfected pregnant women. Most of the women had normal levels of homocysteine and low levels of folate, respectively. Therefore, the systematic diagnosis of malaria should be introduced to pregnant women as a part of the antenatal care.

    Full Text Available Leishmaniosis caused by Leishmania infantum is vector-born severe enzootic disease in dogs. It includes a wide spectrum of clinical symptoms, but the most characteristic are alterations in the hematopoetic system and renal failure. Also, infected animals could be asymptomatic, so the manifestation of L. infantum infection depends on many factors, including host’s immunological status. The aim of this survey was to find parameters related with hematopoetic and renal failure (hematology, biochemical parameters – urea, creatinine, serum proteins in symptomatic and asymptomatic dogs seropositive for canine leishmaniosis. Within the hematological parameters, we found signifi cant differences between symptomatic and asymptomatic dogs in the erythrogram and platelet count, but not in the leukogram. Significant differences between the two groups were found also for urea, creatinine, serum albumin and globulin, but not in serum total protein and A/G ratio. These findings indicate individual variability of the host’s response to infection with L. infantum.

  18. A reservoir of drug-resistant pathogenic bacteria in asymptomatic hosts.

    Gabriel G Perron

    Full Text Available The population genetics of pathogenic bacteria has been intensively studied in order to understand the spread of disease and the evolution of virulence and drug resistance. However, much less attention has been paid to bacterial carriage populations, which inhabit hosts without producing disease. Since new virulent strains that cause disease can be recruited from the carriage population of bacteria, our understanding of infectious disease is seriously incomplete without knowledge on the population structure of pathogenic bacteria living in an asymptomatic host. We report the first extensive survey of the abundance and diversity of a human pathogen in asymptomatic animal hosts. We have found that asymptomatic swine from livestock productions frequently carry populations of Salmonella enterica with a broad range of drug-resistant strains and genetic diversity greatly exceeding that previously described. This study shows how agricultural practice and human intervention may lead and influence the evolution of a hidden reservoir of pathogens, with important implications for human health.

    BACKGROUND: Assessment of myocardial longitudinal function has proved to be a sensitive marker of deteriorating myocardial function in aortic stenosis, demonstrated by both color Doppler tissue imaging and recently by two-dimensional speckle-tracking echocardiography. The aim of this study...... was to compare velocity (color Doppler tissue imaging) and deformation (two-dimensional speckle-tracking echocardiography) in relation to global and regional longitudinal function in asymptomatic and severe symptomatic aortic stenosis. METHODS: In a cross-sectional design, 231 patients with aortic stenosis were...... divided into four groups: asymptomatic moderate aortic stenosis (aortic valve area, 1.0-1.5 cm(2); n = 38), asymptomatic severe aortic stenosis (aortic valve area aortic stenosis with preserved (n = 68) and reduced (

    Full Text Available Introduction. Although intervention in patients with symptomatic carotid disease is generally accepted as beneficial, the management of asymptomatic disease is still controversial. We wanted to introduce and discuss treatment options in a patient with asymptomatic carotid stenosis and high embolic potential lesions of common and internal carotid artery detected by multidetector computed tomography (MDCT. Case Outline. A 78-year-old female patient was admitted to our institution for diagnostics and surgical treatment of asymptomatic high-grade carotid stenosis. Upon admission, color duplex ultrasonography of the carotid arteries revealed the left common carotid artery (CCA stenosis of 50% and the ipsilateral internal carotid artery (ICA stenosis of 60%, while the right CCA was narrowed by 60% and the ipsilateral ICA by 80%. Because of the left subclavian artery (LSA occlusion, also described by ultrasonography, MDCT angiography was performed to assess arterial morphology for possible angioplasty. In addition to LSA occlusion, MDCT angiography surprisingly revealed significant left CCA (>80% and ICA (>70% narrowing by ulcerated plaques with high embolic potential. Surgical treatment of the left CCA and ICA was indicated and Dacron® tubular graft interposition was performed. The postoperative course was uneventful and the patient was discharged from the Institute on the third postoperative day. After the six-month follow-up the patient was doing well with well-preserved graft patency. Conclusion. Although color duplex ultrasonography is reliable and safe imaging modality in carotid stenosis diagnosis, MDCT angiography plays a significant role in patients with asymptomatic carotid stenosis since plaques with high embolic potential could be detected, which, if left untreated, could have severe neurological ischemic consequences.

    Full Text Available Background: Malaria infestation during pregnancy is mostly asymptomatic and untreated especially in unbooked pregnancies. It presents with almost all the fetal complications of overt malaria in pregnancy. The aim of this study was to determine the effect of asymptomatic malaria parasitaemia on the neonates of unbooked parturients delivered at term at the Federal Teaching Hospital, Abakaliki. Materials and Methods: This study was conducted in the labour ward complex of the Federal Teaching Hospital, Abakaliki from March to May 2012. Unbooked pregnant women who fulfilled the inclusion criteria and gave consent were consecutively recruited. Cord blood and placenta tissue were collected for haemoglobin concentration determination and histology, respectively. Birth weights were determined with an electronic weighing machine. Statistical Analysis was done with 2008 Epi Info™ software and level of significant was set at P-value <0.05. Results: A total of 250 unbooked parturients were recruited, of which 194 (77.6% had asymptomatic malaria parasitaemia while 227 (90.8% had placental parasitisation. The prevalence of low birth weight in the study was 16.4%. There was significant relationship between asymptomatic malaria parasitemia and birth weight (X [2] = 43.70, P-value < 0.001. There were no low-birth-weight deliveries among paturients without placental parasitemia. No neonate, however, had anaemia in the study. Conclusion: Asymptomatic malaria parasitemia and placental parasitisation by malaria parasites contribute to the outcome of the foetal birth weight. Asymptomatic malaria parasitaemia and placental parasitaemia did not result in a corresponding foetal anaemia on babies delivered.

    Full Text Available Abstract Echocardiography represents an invaluable diagnostic tool for the detection of intracardiac masses while simultaneously provides information about their size, location, mobility and attachment site as well as the presence and extent of any consequent hemodynamic derangement. A 29-year-old asymptomatic young woman with incidental transthoracic echocardiographic (TTE discovery of an aortic valve mass is presented. The 2-dimensional TTE showed a mobile, pedunculated mass, attached by a thin stalk to the aortic surface of the right coronary aortic cusp at the junction of its base with the anterior aortic wall. The importance of valve sparing tumour resection even in asymptomatic patients is emphasised.

    Full Text Available Renal stones are a common affliction presenting in an acute setting. We report a case of asymptomatic renal stone in an elderly gentleman presenting initially as a discharging lumbar sinus managed by subcapsular nephrectomy and radical excision of the fistula tract. Nephrocutaneous fistula is most commonly associated with tuberculosis, xanthogranulomatous pyelonephritis, and rarely with complicated calyceal stones, and its occurrence with asymptomatic pelvic stones is rare. We present the points in favor of radical open surgery in the management of such patients.

    Full Text Available Abstract Background Increased investment and commitment to malaria prevention and treatment strategies across Africa has produced impressive reductions in the incidence of this disease. Nevertheless, it is clear that further interventions will be necessary to meet the international target of a reversal in the incidence of malaria by 2015. This article discusses the prospective role of an innovative malaria control strategy - the community-based treatment of asymptomatic carriers of Plasmodium falciparum, with artemisinin-based combination therapy (ACT. The potential of this intervention was considered by key scientists in the field at an Advisory Board meeting held in Basel, in April 2009. This article summarizes the discussions that took place among the participants. Presentation of the hypothesis Asymptomatic carriers do not seek treatment for their infection and, therefore, constitute a reservoir of parasites and thus a real public-health risk. The systematic identification and treatment of individuals with asymptomatic P. falciparum as part of a surveillance intervention strategy should reduce the parasite reservoir, and if this pool is greatly reduced, it will impact disease transmission. Testing the hypothesis This article considers the populations that could benefit from such a strategy and examines the ethical issues associated with the treatment of apparently healthy individuals, who represent a neglected public health risk. The potential for the treatment of asymptomatic carriers to impair the development of protective immunity, resulting in a 'rebound' and age escalation of malaria incidence, is also discussed. For policymakers to consider the treatment of asymptomatic carriers with ACT as a new tool in their malaria control programmes, it will be important to demonstrate that such a strategy can produce significant benefits, without having a negative impact on the efficacy of ACT and the health of the target population.

    Benign multicystic mesothelioma is a rare tumour that originates from the abdominal peritoneum with a predisposition to the pelvic peritoneum. It typically affects women of reproductive age. There have been less than 200 cases of this rare neoplasia reported to date. We present the case of a 35-year-old woman who was referred to our centre because of the detection of a peritoneal carcinomatosis during a gynaecological exam. A diagnostic laparoscopy was performed. The findings included multiple cysts appearing as 'a bunch of grapes' occupying the omentum. Biopsies were taken during the surgery and the results showed benign multicystic peritoneal mesothelioma. Benign multicystic mesothelioma can simulate other conditions, such as malignant ovarian tumours or cystic lymphangioma. It is often diagnosed accidentally during surgery performed for another reason. The diagnosis is interoperative, observing multicystic structures grouped as a 'bunch of grapes' containing clear fluid with thin walls made of connective tissue. Immunohistochemistry confirmed mesothelial origin. Surgery is considered the treatment of choice and is based on the removal of the cysts from the abdominal cavity. Hyperthermic intraperitoneal chemotherapy can be considered as a primary treatment in patients with recurrences or even as a part of primary treatment associated with surgery. Survival at 5 years is 100% and invasive or malignant progression is extraordinary. The treatment approach should be multidisciplinary, and the patient should be referred to a referral centre.

    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"?

    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.

    Infection by human papillomavirus (HPV) is a necessary cause of cervical cancer. The purpose of this study was to investigate the prevalence and genotype distribution of HPV infection in Chinese women who were asymptomatic for cervical diseases. Cervical cytology samples were collected from 6479 asymptomatic Chinese women of Liaoning province, and tested for various HPV genotypes using a chip hybridization assay. HPV was found in 10.3% of all the asymptomatic women studied, with the prevalence of high risk HPV (HR HPV) and low risk HPV (LR HPV) being 9.5% and 1.1%, respectively. HPV genotypes 16, 52, and 58 were found the most frequently genotypes in the HR HPV positive women, and were present in 26.2%, 19.4% and 13.8%, respectively. A graph of HR HPV positive infection rates as a function of age is U-shaped, with a peak in women less than 30 years old and a second peak among women older than 50 years. Nearly half of the women infected with either HR HPV or LR HPV presented a normal looking cervix upon visual examination. The current study demonstrates that the epidemiology of HPV infection in asymptomatic Chinese women in Liaoning province is different from that in women from other regions, even from patients with cervical lesions in the same region. These findings could be used to guide the generation and design of an HPV vaccine for this population.

    Ataxia-telangiectasia is a recessive genetic disorder (ATM is the mutated gene) of childhood with severe motor impairments and whereas homozygotes manifest the disorder, heterozygotes are asymptomatic. Structural brain imaging and post-mortem studies in individuals with ataxia-telangiectasia have reported cerebellar atrophy; but abnormalities of motor control characteristic of extrapyramidal dysfunction suggest impairment of broader motor networks. Here, we investigated possible dysfunction in other brain areas in individuals with ataxia-telangiectasia and tested for brain changes in asymptomatic relatives to assess if heterozygocity affects brain function. We used positron emission tomography and (18)F-fluorodeoxyglucose to measure brain glucose metabolism (quantified as µmol/100 g/min), which serves as a marker of brain function, in 10 adults with ataxia-telangiectasia, 19 non-affected adult relatives (12 siblings, seven parents) and 29 age-matched healthy controls. Statistical parametric mapping and region of interest analyses were used to compare individuals with ataxia-telangiectasia, asymptomatic relatives, and unrelated controls. We found that participants with ataxia-telangiectasia had lower metabolism in cerebellar hemispheres (14%, P brain stimulation. Our finding of decreased metabolism in vermis and hippocampus of asymptomatic relatives suggests that heterozygocity influences the function of these brain regions.

    Asymptomatic carriage of gastrointestinal zoonoses is more common in people whose profession involves them working directly with domesticated animals. Subclinical infections (defined as an infection in which symptoms are either asymptomatic or sufficiently mild to escape diagnosis) are important within a community as unknowing (asymptomatic) carriers of pathogens do not change their behaviour to prevent the spread of disease; therefore the public health significance of asymptomatic human excretion of zoonoses should not be underestimated. However, optimal strategies for managing diseases where asymptomatic carriage instigates further infection remain unresolved, and the impact on disease management is unclear. In this review we consider the environmental pathways associated with prolonged antigenic exposure and critically assess the significance of asymptomatic carriage in disease outbreaks. Although screening high-risk groups for occupationally acquired diseases would be logistically problematical, there may be an economic case for identifying and treating asymptomatic carriage if the costs of screening and treatment are less than the costs of identifying and treating those individuals infected by asymptomatic hosts.

    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.

    Fragile X-associated tremor/ataxia syndrome (FXTAS), a late-onset movement disorder affecting FMR1 premutation carriers, is associated with cerebral and cerebellar lesions. The aim of this study was to test whether computational anatomy can detect similar patterns in asymptomatic FMR1 premutation carriers (mean age 46.7 years) with qualitatively normal -appearing grey and white matter on brain MRI. We used a multimodal imaging protocol to characterize brain anatomy by automated assessment of gray matter volume and white matter properties. Structural changes in the hippocampus and in the cerebellar motor network with decreased gray matter volume in lobule VI and white matter alterations of the corresponding afferent projections through the middle cerebellar peduncles are demonstrated. Diffuse subcortical white matter changes in both hemispheres, without corresponding gray matter alterations, are only identified through age × group interactions. We interpret the hippocampal fimbria and cerebellar changes as early alterations with a possible neurodevelopmental origin. In contrast, progression of the diffuse cerebral hemispheric white matter changes suggests a neurodegenerative process, leading to late-onset lesions, which may mark the imminent onset of FXTAS.

    The primary goal when devising strategies to define the start of therapy in HIV infected individuals is to avoid HIV disease progression and toxicity from antiretroviral therapy (ART). Intermediate goals includes, avoiding resistance by suppressing HIV replication, reducing transmission, limiting spread and diversity of HIV within the body and protecting the immune system from harm. The question of how early or late to start ART and achieve both primary and intermediate goals has dominated HIV research. The distinction between early and late treatment of HIV infection is currently a matter of CD4+ T cells count, a marker of immune status, rather than on viral load, a marker of virus replication. Discussions about respective benefits of early or delayed therapy, as well as the best CD4+ T cell threshold during the course of HIV infection at which ART is initiated remains inconclusive. Guidelines issued by various agencies, provide different initiation recommendations. This can be confusing for clinicians and policy-makers when determining the best time to initiate therapy. Optimizing ART initiation strategies are clearly complex and must be balanced between individual and broader public health needs. This review assesses available data that contributes to the debate on optimal time to initiate therapy in HIV-infected asymptomatic individuals. We also review reports on CD4+ T cell threshold to guide initiation of ART and finally discuss arguments for and against early or late initiation of ART.

    Full Text Available Allopurinol is used to treat hyperuricemia (HU in a patient of gout. It is also used to prevent HU in a patient of hematological malignancies who are about to undergo chemotherapy. Allopurinol is usually well-tolerated but it occasionally induces hypersensitivity reactions that manifest after few months of therapy. Cutaneous reactions are pruritic, erythematous, or maculopapular eruptions. Rarely fatal toxic epidermal necrolysis or Stevens-Johnson syndrome may occur. Transient leukopenia or leukocytosis, eosinophilia and elevated transaminases may also occur. HU is not a disease in itself. Its level is highly variable in the general population. Uric acid level is influenced by many factors such as dietary intake of proteins, hypertension, and obesity. Only very rarely patients of AHU may progress to gout and renal stones. Not much data is available that support HU alone in an asymptomatic patient in later life shows the diseases which are associated with HU. Sometimes only lifestyle changes, diet restrictions, alcohol restrictions, and treatment of underlying acquired cause may correct HU. Here, we are presenting a rare case of allopurinol hypersensitivity syndrome in an AHU patient. Our aim is to raise awareness among physicians so that they avoid using unnecessarily allopurinol in AHU patients and also titrate the dose of allopurinol in patients of renal failure. Risk-benefit ratio must be considered in these patients before starting allopurinol. [Int J Basic Clin Pharmacol 2015; 4(6.000: 1302-1304

    Inherited prion diseases are caused by mutations in the gene which codes for prion protein (PrP), leading to proliferation of abnormal PrP isomers in the brain and neurodegeneration; they include Gerstmann-Straeussler-Scheinker disease (GSS), fatal familial insomnia (FFI) and familial Creutzfeldt-Jakob disease (fCJD). We studied two patients with symptomatic inherited prion disease (P102L) and two pre-symptomatic P102L gene carriers using quantitative magnetic resonance spectroscopy (MRS). Short echo time spectra were acquired from the thalamus, caudate region and frontal white matter, metabolite levels and ratios were measured and z-scores calculated for individual patients relative to age-matched normal controls. MRS data were compared with structural magnetic resonance imaging. One fCJD case had generalised atrophy and showed increased levels of myo-inositol (MI) in the thalamus (z=3.7). The other had decreased levels of N-acetylaspartate (z=4) and diffuse signal abnormality in the frontal white matter. Both asymptomatic gene carriers had normal imaging, but increased frontal white matter MI (z=4.3, 4.1), and one also had increased MI in the caudate (z=5.3). Isolated MI abnormalities in asymptomatic gene carriers are a novel finding and may reflect early glial proliferation, prior to significant neuronal damage. MRS provides potential non-invasive surrogate markers of early disease and progression in inherited prion disease. (orig.)

    Full Text Available La úlcera penetrante de aorta (UPA es la ulceración de una placa aterosclerótica que afecta a la lámina elástica interna de la aorta, y que puede evolucionar hacia un hematoma de pared o una disección aórtica si se produce el paso de sangre hacia la capa media. A pesar de que se localiza más frecuentemente en la aorta descendente, puede presentar una alta mortalidad en caso de situarse en la aorta ascendente, donde la cirugía está indicada aunque el paciente se encuentre asintomático. Presentamos el caso de un paciente sin sintomatología con úlcera penetrante de aorta ascendente (UPAA ascendente sometido a sustitución de aorta ascendente por una prótesis vascular.Penetrating aortic ulcer (PAU has been defined as an atherosclerotic plaque ulceration that breaks the internal elastic lamina of the aorta, which may progress to a wall hematoma or aortic dissection in case of blood seeping into the middle layer. Although PAU is commonly located in the descending aorta, the involvement of the ascending aorta can be fatal. Therefore, surgery is indicated even in asymptomatic patients presenting an ascending PAU. We report on an asymptomatic patient with ascending PAU referred for replacement of the ascending aorta with a composite prosthetic graft.

    Gastroesophageal reflux (GER) is very common in pre-term infants. The diagnosis based on symptoms is always questionable. The incidence of GER in symptomatic babies varies from 22% to 85%, but literature regarding the incidence of reflux in asymptomatic pre-term infants is lacking. We used radionuclide scintigraphy to evaluate the incidence of GER in symptomatic as well as asymptomatic pre-term neonates and to assess whether symptoms have any relation with positive scintigraphy. We studied 106 pre-term infants (52 symptomatic, 54 asymptomatic) of less than 34 weeks of gestation, who fulfilled the eligibility criteria. Babies were considered symptomatic in the presence of vomiting, regurgitation, apnea, de-saturations, unexplained bradycardia and recurrent lung collapses. Radionuclide scintigraphy was conducted at post-conceptional age of 32-34 weeks when they were clinically stable for 72 h. Feeding was avoided for 2 h preceding the study. {sup 99m}Tc sulphur colloid was administered in a dose of 1.85 MBq (0.05 mCi) in 1 ml, followed by milk (full feed) through an orogastric tube, prior to imaging under a gamma camera. Reflux was graded as low or high, and reflux episodes during the study were counted. The incidence of GER in the symptomatic group was 71.2% and in asymptomatic babies 61.1% (p=0.275). High-grade reflux was more common (71.4%) than low-grade (28.6%) in both groups (p=0.449). Mean number of reflux episodes in 20 min was 4.4{+-}2.4 in symptomatic babies and 4.9 {+-}2.2 in asymptomatic babies (p=0.321). Babies with positive scintigraphy were similar in birth weight, gestation, time to achieve full feeds, weight and age at discharge to those with negative scintigraphy. GER is common in pre-term infants of less than 34 weeks gestation. The incidence of positive scintigraphy and grade of reflux is not significantly different in symptomatic vs. asymptomatic babies. Though radionuclide scintigraphy is a simple, quick and non-invasive investigation in

    In this paper we formulate a model of dengue fever transmission by considering the presence of asymptomatic and symptomatic compartments. The model takes the form as a system of differential equations representing a host-vector SIR (Susceptible - Infective -Recovered) disease transmission. It is assumed that both host and vector populations are constant. It is also assumed that reinfection of recovered hosts by the disease is possible due to a wanning immunity in human body. We analyze the model to determine the qualitative behavior of the model solution and use the concept of effective basic reproduction number (fraktur Rp) as a control criteria of the disease transmission. The effect of mosquito biting protection (e.g. by using insect repellent) is also considered. We compute the long-term ratio of the asymptomatic and symptomatic classes and show a condition for which the iceberg phenomenon could appear.

    Escherichia coli is the most common organism associated with asymptomatic bacteriuria (ABU). In contrast to uropathogenic E. coli (UPEC), which causes symptomatic urinary tract infections (UTI), very little is known about the mechanisms by which these strains colonize the human urinary tract....... The prototype ABU E. coli strain 83972 was originally isolated from a girl who had carried it asymptomatically for 3 years. Deliberate colonization of UTI-susceptible individuals with E. coli 83972 has been used successfully as an alternative approach for the treatment of patients who are refractory...... to conventional therapy. Colonization with strain 83972 appears to prevent infection with UPEC strains in such patients despite the fact that this strain is unable to express the primary adhesins involved in UTI, viz. P and type 1 fimbriae. Here we investigated the growth characteristics of E. coli 83972 in human...

    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.

    Objective: To investigate the presence of Microsporum canis in pelage of asymptomatic cats for dermatophytosis, in south region of Rio Grande do Sul, Brazil, and evaluate its importance in epidemiology of dermatophytosis in the study area. Methods: A total of 60 domestic cats were evaluated for the presence of Microsporum canis. The animals were divided into three groups of 20 felines. Each group consisted of exclusively domiciled, semi-domiciled and rural animals. Samples were collected following the carpet-square technique. The microorganisms were cultivated under laminar flow in mycosel agar and grown in a greenhouse. Results: All the cats of the three groups analysed had negative cultures for dermatophytes. In 85% of the dishes, there was a growth of environmental saprophytic fungi such as Aspergillus sp., Fusarium sp. and Penicillium sp. Conclusions: Thus, asymptomatic cats for dermatophytes did not show importance in the transmission and maintenance of the disease in southern of Rio Grande do Sul, Brazil.

    2005-01-01

    Summary: To further investigate the vertical transmission route of human papillomavirus (HPV) and the indication for the choice of mode of delivery, the infective status of 152 asymptomatic pregnant wemen and the maternal-fetal transmission were studied. By using general primers in polymerase chain reaction (GP-PCR) combined with restriction fragment length polymorphism analysis, HPV DNA positive rate in cervical secretions and venous blood in asymptomatic pregnant women was 36.21 % and 52.78 %, respectively, and the identified genotypes were mainly HPV16 and 18. The maternal-fetal transmission rate of HPV via genital tract as well as blood was 40.91 % and 57.89 %, respectively. It was concluded that besides the transmission route of genital tract and amniotic fluid, there was also transplacental transmission of HPV in utero. Therefore,in our opinion, it is not an absolut indication to perform a cesarean delivery for the pregnant women with HPV asymtomatic genital infection.

    AIM: To prospectively assess the prevalence of paraurethral cystic structures in asymptomatic adult women. PATIENTS AND METHODS: One hundred and forty consecutive women undergoing endovaginal sonography with no history of lower urinary tract symptoms. RESULTS: Paraurethral cystic structures were identified in 4/140 subjects (2.9%). Ultrasound assessment allowed rapid definition of the site, size and vascularity of these lesions and was well tolerated by the patient. CONCLUSION: This is the first prospective ultrasound study to determine the prevalence of paraurethral cystic structures in a large consecutive cohort of asymptomatic women. Our findings are in accordance with previously published post-mortem data and surgical series which have estimated the prevalence of paraurethral cystic structures to be between 1 and 6%.

    Enterotoxigenic Escherichia coli (ETEC) is one of the major causes of diarrhea in children and travelers in developing countries. ETEC colonization factors (CFs) are virulence determinants considered as protective antigens and major targets for vaccine development against ETEC infections. One of the most prevalent CFs, coli surface antigen 6 (CS6), a non-fimbrial polymeric protein consisting of two major subunits, CssA and CssB, is produced by approximately 25-35% of ETEC worldwide. We could isolate only CS6-producing ETEC strains from two diarrheal patients and one asymptomatic carrier, but we could not detect CssA- or CssB-specific antibodies in the feces and blood of two patients convalescing from natural ETEC infection and of an asymptomatic carrier using western blotting. Therefore, in order to protect against infection with CS6-producing ETEC, protective levels of CS6 immunity should be incorporated in any future vaccines against ETEC.

    Objective: To determine the prevalence and clinical impact of rotator cuff tears in asymptomatic volunteers. Materials and Methods: Sonographic examinations of the shoulder of 212 asymptomatic individuals between 18 and 85 years old were performed by a single experienced operator. The prevalence and location of complete rotator cuff tears were evaluated. The clinical assessment was based on the Constant Score. Magnetic resonance imaging (MRI) of the shoulder was obtained in those patients where US showed rotator cuff pathology. Results: Ultrasound showed a complete rupture of the supraspinatus tendon in 6% of 212 patients from 56 to 83 years of age (mean: 67 years). MRI confirmed a complete rupture of the supraspinatus tendon in 90%. All patients reported no functional deficits, although strength was significantly lower in the patient group with complete supraspinatus tendon tear (P<0.01). Conclusion: There is a higher prevalence in older individuals of rotator cuff tendon tears that cause no pain or decrease in activities of daily living.

    Full Text Available Abstract Background Asymptomatic malaria can be observed in both stable endemic areas and unstable transmission areas. However, although much attention has been given to acute malaria infections, relatively little attention has been paid to asymptomatic malaria. Nonetheless, because the asymptomatic host serves as a reservoir for the malaria parasite, asymptomatic malaria is now recognized as an important obstacle to malaria elimination. Asymptomatic malaria is also associated with anaemia, a global public health problem with serious consequences on human health as well as social and economic development. In Lao People’s Democratic Republic (Lao PDR, malaria, anaemia, and malnutrition are serious public health concerns. However, few studies have focused on the relationship between these variables. Therefore, this study investigated the relationship between asymptomatic malaria, growth status, and the prevalence of anaemia among children aged 120 months old or younger in rural villages in Lao PDR. Methods In December 2010 and March 2011, data were collected from five villages in Savannakhet province. Anthropometric measurements, blood samples, and malaria rapid diagnostic tests were conducted. The presence of malaria was confirmed with polymerase chain reaction assays for Plasmodium falciparum. Underweight status, stunting, and anaemia were defined according to World Health Organization standards. Results The mean age of participants (n = 319 was 88.3 months old (Standard Deviation: 20.6, ranged from 30–119 months old, and 20 participants (6.3 % had an asymptomatic malaria infection, 92 (28.8 % were anaemic, 123 (38.6 % were underweight, and 137 (42.9 % were stunted. Stunted children were more likely to be infected with asymptomatic malaria [odds ratio (OR 3.34, 95 % confidence interval (CI 1.25–8.93], and asymptomatic malaria was associated with anaemia [OR 5.17, 95 % CI 1.99–13.43].

    This study was performed to determine the prevalence of bifid mandibular condyles (BMCs) in asymptomatic and symptomatic temporomandibular joint (TMJ) subjects with no traumatic history, and to assess their impact on clinical and radiographic manifestations of TMJ. A total of 3,046 asymptomatic and 4,378 symptomatic patients were included in the study. Cone-beam computed tomography (CBCT) images were reviewed for bifid condyles. T-tests were used to compare the frequency of BMCs when stratified by symptom, gender, and side. In BMC patients, the clinical features of pain and noise, osseous changes, and parasagittal positioning of the condyles were compared between the normally shaped condyle side and the BMC side using chi-squared tests. Fifteen (0.49%) asymptomatic and 22 (0.50%) symptomatic patients were found to have BMCs. Among the bilateral cases, the number of condyles were 19 (0.31%) and 25 (0.29%), respectively. No statistically significant differences were found between asymptomatic and symptomatic patients, between female and male patients, or between the right and left sides (p>0.05). Compared with the normally shaped condyle side, the BMC side showed no statistically significant differences in the distribution of pain and noise, parasagittal condylar position, or condylar osseous changes, with the exception of osteophytes. In the symptomatic group, osteophytes were found more frequently on the normally shaped condyle side than the BMC side (p<0.05). BMCs tended to be identified as an incidental finding. The presence of BMC would not lead to any TMJ symptoms or cause osseous changes.

    Full Text Available Background: Asymptomatic bacteriuria is common in women with prevalence of 4-7% in pregnancy. The traditional reference test for bacteriuria is quantitative culture of urine which is relatively expensive time consuming and laborious. The aim of this study was to know the prevalence of asymptomatic bacteriuria in pregnancy, to identify pathogens and their antibiotic susceptibility patterns and to device a single or combined rapid screening method as an acceptable alternative to urine culture. Methods: Clean catch mid-stream urine were collected from 250 pregnant women aged between 18-45 years attending antenatal clinic, for a period of one year (November 2008-2009. Screening tests such as gram staining of uncentrifuged urine, pus cell count, nitrite test and leukocyte esterase test were done. Identification of organisms and antibiotic sensitivity tests were performed as per standard methods. Results: Out of the 250 pregnant women, 21 (8.4% had significant bacteriuria. High percentage of asymptomatic bacteriuria was seen in 2nd trimester (42.86% and in primigravidas (52.38%. E. coli (57.14% was the most common organism. Among screening tests gram staining of uncentrifuged urine had a sensitivity of 85.71%. Nitrite and leukocyte esterase tests alone showed sensitivity of 71.42%. However, the combination of these two tests, either tests positive, showed sensitivity and negative predictive value of 90.47% and 99.09% respectively. Conclusion: Asymptomatic bacteriuria in pregnancy can be identified by simple and combined rapid screening methods and urine culture along with antibiogram so that early treatment can be started thereby preventing complications.

    Background Most European and North American clinical practice guidelines recommend screening for asymptomatic bacteriuria (ASB) as a routine pregnancy test. Antibiotic treatment of ASB in pregnant women is supposed to reduce maternal upper urinary tract infections (upper UTIs) and preterm labour. However, most studies supporting the treatment of ASB were conducted in the 1950s to 1980s. Because of subsequent changes in treatment options for ASB and UTI, the applicability of findings from thes...

    Ultrasound (US) specifically looking for asymptomatic renal calcifications that may be renal stones is typically not done in the terrestrial setting. Standard abdominal US without a renal focus may discover incidental, mineralized renal material (MRM); however punctate solid areas of MRM is less than 3 mm are usually considered subclinical. Detecting these early calcifications before they become symptomatic renal stones is critical to prevent adverse medical and mission outcomes during spaceflight.

    Assess extensor carpi ulnaris (ECU) tendon position in the ulnar groove, determine the frequency of tendon ''dislocation'' with the forearm prone, neutral, and supine, and determine if an association exists between ulnar groove morphology and tendon position in asymptomatic volunteers. Axial proton density-weighted MR was performed through the distal radioulnar joint with the forearm prone, neutral, and supine in 38 asymptomatic wrists. The percentage of the tendon located beyond the ulnar-most border of the ulnar groove was recorded. Ulnar groove depth and length was measured and ECU tendon signal was assessed. 15.8 % of tendons remained within the groove in all forearm positions. In 76.3 %, the tendon translated medially from prone to supine. The tendon ''dislocated'' in 0, 10.5, and 39.5 % with the forearm prone, neutral and supine, respectively. In 7.9 % prone, 5.3 % neutral, and 10.5 % supine exams, the tendon was 51-99 % beyond the ulnar border of the ulnar groove. Mean ulnar groove depth and length were 1.6 and 7.7 mm, respectively, with an overall trend towards greater degrees of tendon translation in shorter, shallower ulnar grooves. The ECU tendon shifts in a medial direction when the forearm is supine; however, tendon ''dislocation'' has not been previously documented in asymptomatic volunteers. The ECU tendon medially translated or frankly dislocated from the ulnar groove in the majority of our asymptomatic volunteers, particularly when the forearm is supine. Overall greater degrees of tendon translation were observed in shorter and shallower ulnar grooves. (orig.)

    Giant prostatic hyperplasia is a rare condition characterized by very high volume benign prostatic enlargement (>500g). Few cases have been reported so far and most of them are associated with severe lower urinary symptoms. We report the first case of asymptomatic giant prostatic hyperplasia in an elderly man who had a 720g prostate adenoma, sudden gross hematuria and hypovolemic shock. The patient was successfully treated with open transvesical prostatectomy and had an uneventful postoperative recovery.

  15. Frequency of Chlamydia Trachomatis in Symptomatic and Asymptomatic Non-pregnant Women in Golestan Province

    Samira Okhli (MSc

    2016-06-01

    Full Text Available Background and Objective: Chlamydia trachomatis is one of the most common causes of genital infection in men and women. Genital chlamydial infections in women are clinically asymptomatic in 70-80% of the cases; therefore, the lack of timely diagnosis and treatment leads to complications such as infertility and ectopic pregnancy. The aim of this study was to evaluate the frequency of chlamydial infection in symptomatic and asymptomatic women in the Golestan province. Methods: This cross-sectional study was conducted on 150 cervical swab samples obtained from 150 women referred to the clinic, after obtaining written consent and completion of questionnaires. The swab samples were transferred to laboratory in phosphate-buffered saline solution and DNA extraction was carried out using phenol-chloroform and boiling methods. The frequency of chlamydial infection was evaluated by PCR. Results: None of the tested samples were found as Chlamydia-positive. Conclusion: The findings require that some more extensive research with larger sample sizes and dispersed population be performed to determine the true prevalence. Considering the serious complications of chlamydial infections and its asymptomatic nature, a highly sensitive and specific method such as PCR should be used to detect Chlamydia. It is suggested that this method be used along with a complementary test to obtain the results that are more accurate. Furthermore, conducting simultaneous studies on other populations at risk will be very helpful in obtaining representable national data.

    Full Text Available Asymmetric dimethylarginine (ADMA is an endogenous nitric oxide synthase (NOS inhibitor known as a mediator of endothelial dysfunction and atherosclerosis. Circulating ADMA levels are correlated with cardiovascular risk factors such as hypercholesterolemia, arterial hypertension, diabetes mellitus, hyperhomocysteinemia, age and smoking. We assessed the relationship between ADMA values and site-specific association of asymptomatic carotid atherosclerosis (intima-media thickness (CIMT and plaque in elderly subjects. One hundred and eighty subjects underwent a complete history and physical examination, determination of serum chemistries and ADMA levels, and carotid ultrasound investigation (CUI. All subjects had no acute or chronic symptoms of carotid atherosclerosis. Statistical analyses showed that high plasma levels of ADMA/SDMA were positively correlated to carotid atherosclerosis (CIMT and plaque (p < 0.001, with significant site-specific association. Total cholesterol, low density lipoprotein cholesterol, triglycerides and C-reactive protein plasma concentrations were significantly associated with asymptomatic carotid atherosclerosis (p < 0.001. High serum concentrations of ADMA and SDMA were associated with carotid atherosclerotic lesions as measured by CIMT ad plaque and may represent a new marker of asymptomatic carotid atherosclerosis in elderly subjects.

    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.) With 3 figs., 1 tab., 24 refs.

    To describe magnetic resonance (MR) imaging findings in the wrists of asymptomatic subjects that might be confused with pathologic findings. MR examination of the dominant wrist was performed in 30 asymptomatic volunteers aged 22-49 years using pre-contrast and post-contrast sequences in the coronal and axial planes. The bases of the metacarpals, the carpus and the distal radius and ulna were evaluated by two musculoskeletal radiologists for lesions, notches, blood vessels and synovial enhancement. There were 24 bright osseous lesions (erosions, intraosseous ganglia, oedema or cysts) in 14 subjects. Intraosseous blood vessels were seen in all but one wrist examined, most commonly in the capitate and lunate bones. Enhancement was present in 26 of 27 notches identified at the base of the second metacarpal and less commonly in the capitate, hamate and triquetral notches. A small joint effusion was present in 14 subjects. Joint or soft-tissue enhancement was identified in 16 wrists. Many MR abnormalities and variants may be detected in the wrists of asymptomatic subjects. Many of these could be confused with pathologic findings usually associated with inflammatory arthritis.

The aim of this cross-sectional study is to prospectively detect the prevalence of chlamydia trachomatis (CT, neisseria gonorrhoeae (NG, mycoplasma genitalium (MG, and high risk human papillomavirus (HR-HPV, and syphilis in a population of asymptomatic sexually active MSM. Methods: Rectal, pharyngeal, and urine samples for CT, NG, MG, and HR-HPV were analyzed in 116 MSM patients attending the clinic for their routine follow-up during the period the study was conducted: 99 patients were issued from the clinic routine follow-up for their HIV infection, and 17 attended the clinic because they were sexual partners of an HIV infected male. Results: An STI was found in 16% of the patients (19/116, with at least one bacterial strain (CT, NG, or MG found in one site (the pharynx, rectum, or urine. Conclusions: In this study, 16% of the MSM reporting recent RAI were asymptomatic carriers of rectal CT, NG, or MG. According to the high prevalence of asymptomatic STIs found in our MSM population and in other studies, prevention efforts in the form of counseling about the risk of STI need to be done in the population of MSM.

    The aim of this study was to assess the clinical usefulness of sonographic endometrium thickness measurement in asymptomatic postmenopausal women with endometrial fluid collection. Fifty-two asymptomatic postmenopausal women with endometrial fluid, who underwent endometrial sampling were evaluated. Histopathological findings revealed that 25 (48.1%) women had insufficient tissue, 20 (38.4%) had atrophic endometrium and 7 (13.5%) had endometrial polyps. No case of malignancy was found. There was no statistically significant difference between the various histopathological categories (insufficient tissue, atrophic endometrium and polyp) with regard to the mean single-layer endometrial thickness (1.54 ± 0.87, 2.04 ± 1.76 and 1.79 ± 0.69 mm, respectively, p = 0.436). Out of 44 patients with endometrial thickness of less than 3 mm, 38 (86.4%) had atrophic changes or insufficient tissue and 6 (13.6%) had endometrial polyps. In conclusion, if the endometrial thickness is 3 mm or less, endometrial sampling is not necessary in asymptomatic postmenopausal women with endometrial fluid.

    The athletic activity of the adult U.S. population has increased markedly in the last 20 years. To evaluate the possible long-term effects of such activity on the cervical and lumbar spine, we studied a group of asymptomatic currently very active lifelong male athletes over age 40 (41-69 years old, av. age 53). Nineteen active, lifelong male athletes were studied with MRI and the results compared with previous imaging studies of other populations. An athletic history and a spine history were also taken. Evidence of asymptomatic degenerative spine disease was similar to that seen in published series of other populations. Degenerative changes including disk protrusion and herniation, spondylosis, and spinal stenosis were present and increased in incidence with increasing patient age. In this group, all MRI findings proved to be asymptomatic and did not limit athletic activity. The incidence of lumbar degenerative changes in our study population of older male athletes was similar to those seen in other populations. 14 refs., 8 figs., 1 tab.

    AIM: To evaluate the infection and genotype distribution of hepatitis B virus (HBV) in ethnic groups in Yunnan, China. METHODS: Two thousand five hundred and eighty-four asymptomatic local people from 10 ethnic groups were investigated in Yunnan, China. Infection and genotype distribution were evaluated by serological and genetic methods. Genotyping was verified by sequencing. Ethnic genotype distribution was compared by proportion test. RESULTS: Four types of infection model based on HBV serum markers were identified, and the average HBV infection rate was 5.7% in those asymptomatic local people. The genotype prevalence was 59.6% for B, 21.1% for C and 19.3% BC; subgenotypes Ba, Cs and Ce were identified in this study. Hepatitis B surface antigen-positive rate and the proportion of genotype B were significantly lower in ethnic groups with a northern origin compared to those with a southern origin (50% vs 73.9%, P = 0.037; 4.2% vs 10.5%, P = 0.000). CONCLUSION: Genotype B is dominant and genotype BC has high occurrence in asymptomatic local ethnic groups in Yunnan. HBV infection status and genotype distribution may associate with ethnic origin.

    Specific patterns of developmental adaptation of the proximal femur have been recognized in some sports. Gymnastics are characterized by repetitive axial loading and hip rotations in combination with extreme hip positions. It is unknown how and if these forces can affect an immature skeleton in the long term. We sought to evaluate this, by means of magnetic resonance imaging of the hip and groin of such elite asymptomatic athletes. We performed a case-control comparative MR imaging study of both hips and groin of 12 (7 male, 5 female) skeletally mature young (mean age 18.6 years) asymptomatic international level gymnasts with a minimum of 10 years' training with age-matched non-athletes. At the time of recruitment, none of the athletes had a recorded musculoskeletal complaint or injury in the anatomical area around the hip. The study showed that elite gymnasts share four common morphological characteristics on MRI that deviate from normal and are considered to be the result of adaptational changes to the specific sport: high centre-column-diaphysis angle (coxa valga140 on average), ligamentum teres hypertrophy, friction of the iliotibial band with oedema surrounding the greater trochanter, and a high incidence (62.5 %) of radiological appearances of ischiofemoral impingement. Our study showed that elite gymnasts share four common morphological characteristics on MRI that deviate from normal. These findings were in asymptomatic subjects; hence, radiologists and sports physicians should be aware of them in order to avoid unnecessary treatment. (orig.)

    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)

    AIM:To identify the prevalence,risk factors and manifestations of asymptomatic hepatitis C virus (HCV) infection in Egyptian children.METHODS:Children at the age of 1-9 years were screened for HCV antibodies and alanine aminotransferase (ALT) levels. Every child with elevated ALT and/or detectable HCV antibodies was tested for HCV RNA by RT-PCR and compared with two negative controls for risk factors and signs and symptoms of liver disease.RESULTS:We screened 1042 children,six of them had elevated ALT,negative HCV antibody and positive RNA,likely representing acute hepatitis C cases. Fifteen children were HCV seropositive,5 of them were HCV RNA positive. Asymptomatic HCV infection was present in 2.02% (positive results for either HCV antibodies or HCV-RNA or both). Symptoms such as diarrhea,abdominal pain,history of fatigue and school absence because of illness and risk factors such as dental care were significantly more common among HCV positive cases than among controls. None of the HCV positive children was diagnosed as having signs of advanced liver disease upon clinical or ultrasonographic examination.CONCLUSION:Asymptomatic HCV infection is detectable in 2.02% Egyptian children.

    The purpose of this prospective investigation was to determine whether an alteration in urine pH, either by itself or in combination with other rapid screening tests, could be used to identify asymptomatic bacteriuria in pregnant women. Clean catch urine specimen was used to evaluate 510 asymptomatic obstetric patients. Urine specimens were tested for pH, leukocyte esterase activity, and the presence of nitrites. The pH, leukocyte esterase activity, and nitrite reaction were evaluated singly and in combination to determine if these variables could be used to predict significant bacteriuria. Twenty-four (4.8%) patients had positive cultures for E. coli. The mean pH of the infected population was not significantly different from that of the uninfected population. The performance parameters of pH, singly and in combination with the leukocyte esteras and nitrite status, were poor. We concluded that the identification of urine pH is not of value in detecting asymptomatic bacteriuria.

    Published descriptions of nonseptic arthritis of the equine temporomandibular joint (TMJ) are rare and large studies investigating variations in the TMJ for asymptomatic horses are lacking. The objectives of this cross-sectional, retrospective, multi-institutional study were to describe anatomical variations in the TMJ detected using computed tomography (CT) in an equid population asymptomatic for TMJ disease and determine whether these variations were associated with patient signalment, reason for CT examination, or CT slice width. Medical records at eight hospitals were searched for horses that had head/neck CT scans and no clinical signs of TMJ disease. Age, breed, sex, clinical presentation, and CT slice width data were recorded. Alterations in CT contour and density of the mandibular condyles, mandibular fossae, and TMJ intra-articular discs were described for each horse. Generalized logistic regression was used to test associations between anatomical variations and horse age. A total of 1018 horses were sampled. Anatomical variations were found in TMJ CT images for 40% of horses and 29% of joints. These were dichotomous with regard to age. Horses horses commonly had spherical hypodensities within the mandibular condyles consistent with bone cysts; and hyperdense regions of the intra-articular disc consistent with dystrophic mineralization. Findings indicated that TMJ anatomic variations were common in CT images of younger and older horses asymptomatic for TMJ disease. Future studies are needed to more definitively characterize these CT variations using gross pathology and histopathology.

    Full Text Available We have examined by gelatin-SDS-PAGE the protease activity in cell lysates of Giardia duodenalis trophozoites of two axenic strains isolated in Brazil from a symptomatic patient (BTU-11 and an asymptomatic carrier (BTU-10, and the reference strain Portland 1 (P1. The proteolysis band patterns showed differences among strains isolated from asymptomatic and symptomatic individuals. The lysate of the strain BTU-10, showed only five hydrolysis bands, while a greater number of bands (10-11 bands was seen in strains BTU-11 and P1. The protease activity in all lysates was inhibited by cysteine (E-64 and iodoacetamide and serine proteases (TPCK and TLCK inhibitors, but not by PMSF and EDTA. In general, the results revealed protease activities in G. duodenalis trophozoites of Brazilian axenic strains and the predominance of cysteine proteinases. It should be stressed the inter-strain difference in hydrolysis band patterns observed between strains isolated from symptomatic patients and the strain obtained from an asymptomatic carrier.

    Full Text Available Prion transmission can occur by blood transfusion in human variant Creutzfeldt-Jakob disease and in experimental animal models, including sheep. Screening of blood and its derivatives for the presence of prions became therefore a major public health issue. As infectious titer in blood is reportedly low, highly sensitive and robust methods are required to detect prions in blood and blood derived products. The objectives of this study were to compare different methods--in vitro, ex vivo and in vivo assays--to detect prion infectivity in cells prepared from blood samples obtained from scrapie infected sheep at different time points of the disease. Protein misfolding cyclic amplification (PMCA and bioassays in transgenic mice expressing the ovine prion protein were the most efficient methods to identify infected animals at any time of the disease (asymptomatic to terminally-ill stages. However scrapie cell and cerebellar organotypic slice culture assays designed to replicate ovine prions in culture also allowed detection of prion infectivity in blood cells from asymptomatic sheep. These findings confirm that white blood cells are appropriate targets for preclinical detection and introduce ex vivo tools to detect blood infectivity during the asymptomatic stage of the disease.

    This is a study of 189 women attending a family planning clinic in rural South Africa to determine the prevalence of asymptomatic and unrecognized genital tract infections. Genital samples were taken from these women to diagnose infection with Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, Candida albicans, Treponema pallidum, and HIV, and to diagnose bacterial vaginosis. Among the 189 women, 41 (22%) reported having had an STD treated in the preceding 12 months. By direct questioning, 74 women stated the following symptoms: genital itch -- 38 (20%); vaginal discharge -- 56 (30%); dysuria -- 33 (18%); dyspareunia -- 22 (12%); and genital ulcers -- 4 (2%). 45 (24%) women had more than one symptom. 119 (63%) women had at least one genital infection, and 49 (26%) had multiple infections. Most of the infections were asymptomatic; while those that were symptomatic, were unrecognized or not reported. Results showed a high prevalence of genital tract infection among the participating women, with most of their infections remaining asymptomatic or unrecognized. Thus, strategies to detect and treat genital tract infections in rural South Africa need to be developed.

The aim of this study was to evaluate the prevalence of silent myocardial ischemia in a group of patients with asymptomatic carotid stenosis.Methods: A total of 37 patients with asymptomatic carotid plaques, without chest pain or dyspnea, was investigated. These patients were studied for age, sex, hypertension, diabetes, dyslipidemia, smoking, and family history of cardiac disease, and underwent technetium-99 m sestamibi myocardial stress-rest scintigraphy and echo-color Doppler examination of carotid arteries.Results: A statistically significant relationship (P = 0.023 was shown between positive responders and negative responders to scintigraphy test when both were tested for degree of stenosis. This relationship is surprising in view of the small number of patients in our sample. Individuals who had a positive scintigraphy test had a mean stenosis degree of 35% ± 7% compared with a mean of 44% ± 13% for those with a negative test. Specificity of our detection was 81%, with positive and negative predictive values of 60% and 63%, respectively.Conclusion: The present study confirms that carotid atherosclerosis is associated with coronary atherosclerosis and highlights the importance of screening for ischemic heart disease in

    Full Text Available During the last decade much progress has been made in reducing malaria transmission in Macha, Southern Province, Zambia. Introduction of artemisinin combination therapies as well as mass screenings of asymptomatic carriers is believed to have contributed the most. When an endemic malaria situation is moving towards a non-endemic situation the resident population loses acquired immunity and therefore active case detection and efficient surveillance is crucial to prevent epidemic outbreaks. Our purpose was to evaluate the impact of cell phone surveillance and geographical information systems on malaria control in Macha. Furthermore, it evaluates what screening and treatment of asymptomatic carriers and implementation of rapid diagnostic tests in rural health care has led to. Ten in-depth semistructured interviews, field observations and data collection were performed at the Macha Research Trust and at surrounding rural health centers. This qualitative method was inspired by rapid assessment procedure. The cell phone surveillance has been easily integrated in health care, and its integration with Geographical Information Systems has provided the ability to follow malaria transmission on a weekly basis. In addition, active case detection of asymptomatic carriers has been fruitful, which is reflected in it soon being applied nationwide. Furthermore, rapid diagnostic tests have provided rural health centers with reliable malaria diagnostics, thereby decreasing excessive malaria treatments and selection for drug resistance. This report reflects the importance of asymptomatic carriers in targeting malaria elimination, as well as development of effective surveillance systems when transmission decreases. Such an approach would be cost-efficient in the long run through positive effects in reduced child mortality and relief in health care.

    BACKGROUND: Soccer players are commonly affected by long-standing adductor-related groin pain (ARGP), but the clinical significance of MRI findings in these athletes is largely unknown. Our aims were (1) to evaluate whether MRI findings are associated with long-standing ARGP in soccer players, (2......) to assess MRI findings in asymptomatic soccer players and non-soccer playing controls. METHODS: This cross-sectional study included 28 male soccer players with long-standing ARGP, 17 male asymptomatic soccer players and 20 male asymptomatic non-soccer playing athletes of matching age and athletic exposure...... soccer players displayed different positive MRI findings, and asymptomatic soccer players had significantly higher odds (OR ranging from 6.3 to 13.3) for BMO, adductor tendinopathy and degenerative changes than non-soccer players. CONCLUSIONS: ARGP in soccer players was associated with central disc...

    Purpose: To evaluate the utility of carotid ultrasound in patients with asymptomatic Hollenhorst plaques. Methods: Retrospective chart review of 237 patients diagnosed with Hollenhorst plaques between 1996 and 2004. The baseline cardiovascular risk profile, medications, and carotid ultrasound findings were documented. Retinal ischemia, myocardial ischemia, and cerebrovascular events during follow-up were noted. Results: There was no statistically significant difference in the proportion of patients with carotid stenosis >40% between symptomatic (n=60) and asymptomatic (n=177) patients (32.7% vs 22.7%; P=.192, one-way ANOVA). However, symptomatic patients were statistically more likely to have stenosis >69% (25% compared with 9.2% in the asymptomatic group; P=.008, one-way ANOVA). Among asymptomatic patients, those with carotid bruit (27.1%) were more likely to have moderate carotid stenosis >40% (55.6% vs 18.6% in patients without bruit; P=.0008, one-way ANOVA) and significant stenosis >69% (37% vs 4.3% in patients without bruit; P=.0001, one-way ANOVA). Follow-up data was obtained from 32 symptomatic patients (39.6 ± 22.9 months) and 100 asymptomatic patients (41.3 ± 21.8 months). Vascular and neurologic event rates were similar between the two groups. Conclusions: Hollenhorst plaques are a marker of significant carotid disease irrespective of retinal symptoms. Carotid auscultation remains important in the examination of patients with Hollenhorst plaques and increases the yield of asymptomatic patients diagnosed with carotid stenosis. The presence of visual symptoms on presentation did not correlate with an increased risk of death or stroke compared to asymptomatic patients during follow-up. Therefore all patients with asymptomatic plaques should have a medical workup, including carotid ultrasonography. PMID:24072943

    Full Text Available Background: Sexually transmitted diseases (STD are a major health problem affecting mostly young people in both developing and developed countries. STD in women causes both acute morbidity and complications such as infertility, ectopic pregnancy, low-birth weight, and prematurity. Aims: The aim of the study is to assess the prevalence of bacterial vaginosis, vaginal candidiasis, and trichomoniasis among asymptomatic females attending STD outpatient department in a tertiary care hospital in South India. Materials and Methods: A retrospective analysis of data collected from clinical records of 3000 female patients of age 18 to 49 over a period of 12 months (July 2014 to June 2015 was carried out at the Institute of Venereology, Madras Medical College. Complete epidemiological, clinical, and investigational data were recorded and analyzed for the prevalence of bacterial vaginosis, vaginal candidiasis, and trichomoniasis among asymptomatic patients. Results: About 48.37% (228/470 of bacterial vaginosis patients were asymptomatic. Nearly 45.38% (116/235 of vaginal candidiasis patients were asymptomatic and 30.35% (26/87 of trichomoniasis patients were asymptomatic. The above infections were common in the age group 25–35. Conclusion: Holistic screening protocol was incorporated for all female patients attending STD clinic even if asymptomatic and should be treated accordingly to prevent the acquisition of other serious sexually transmitted infections.

    Full Text Available Abstract Background Urinary tract infection (UTI is a common cause of childhood morbidity and mortality in the tropics. Children with sickle cell anemia (SCA may have compromised kidney function arising from repeated vaso-occlusive episodes and recurrent symptomatic or asymptomatic UTI. Objectives This study aims at determining the prevalence of asymptomatic bacteriuria and sensitivity pattern in children with homozygous sickle haemoglobin compared to children with normal haemoglobin. Methods One hundred children with SCA in stable state and 100 children with normal haemoglobin aged 2-12 years were screened for asymptomatic bacteriuria using midstream urine samples. The samples were incubated aerobically at 37°C for 24 hours within one hour of collection. Children whose urine samples yielded significant bacteriuria (≥105cfu/ml on two consecutive cultures were regarded as having asymptomatic bacteriuria. Results Asymptomatic bacteriuria was noted in 6% of children with SCA and occurred more in females than males (F: M = 5:1 when compared to 2% in children with normal haemoglobin. Escherichia coli was the commonest organism isolated (33.3%. All the organisms were resistant to co-trimoxazole and ampicillin while most were sensitive to gentamicin, ceftriaxone and the quinolones. Conclusion The risk of asymptomatic bacteriuria is three times more common in children with sickle cell anemia than in children with normal haemoglobin. It is therefore important to screen SCA patients, especially the females for UTI and should be treated according to the sensitivity result of the cultured organisms.

    Full Text Available Abstract Background The role of asymptomatic carriers of toxigenic Clostridium difficile (TCD in nosocomial cross-transmission remains debatable. Moreover, its relevance in the elderly has been sparsely studied. Objectives To assess asymptomatic TCD carriage in an acute care geriatric population. Methods We performed a prospective cohort study at the 296-bed geriatric hospital of the Geneva University Hospitals. We consecutively recruited all patients admitted to two 15-bed acute-care wards. Patients with C. difficile infection (CDI or diarrhoea at admission were excluded. First bowel movement after admission and every two weeks thereafter were sampled. C. difficile toxin B gene was identified using real-time polymerase chain-reaction (BD MAXTMCdiff. Asymptomatic TCD carriage was defined by the presence of the C. difficile toxin B gene without diarrhoea. Results A total of 102 patients were admitted between March and June 2015. Two patients were excluded. Among the 100 patients included in the study, 63 were hospitalized and 1 had CDI in the previous year, and 36 were exposed to systemic antibiotics within 90 days prior to admission. Overall, 199 stool samples were collected (median 2 per patient, IQR 1-3. Asymptomatic TCD carriage was identified in two patients (2 %. Conclusions We found a low prevalence of asymptomatic TCD carriage in a geriatric population frequently exposed to antibiotics and healthcare. Our findings suggest that asymptomatic TCD carriage might contribute only marginally to nosocomial TCD cross-transmission in our and similar healthcare settings.

    We aimed to investigate the frequency of asymptomatic acute brain MRI abnormalities accompanying optic neuritis (ON) or myelitis in neuromyelitis optica spectrum disorder (NMOSD) patients with aquaporin-4 antibodies (AQP4-Ab). We reviewed 324 brain MRI scans that were obtained during acute attacks of ON or myelitis, in 165 NMOSD patients with AQP4-Ab. We observed that acute asymptomatic NMOSD-typical brain lesions accompanied 27 (8%) acute attacks of ON or myelitis in 24 (15%) patients. The most common asymptomatic brain abnormalities included edematous corpus callosum lesions (n = 17), followed by lesions on the internal capsule and/or cerebral peduncle lesions (n = 9), periependymal surfaces of the fourth ventricle (n = 5), large deep white matter lesions (n = 4), periependymal cerebral lesions surrounding the lateral ventricles (n = 3), and hypothalamic lesions (n = 1). If asymptomatic NMOSD-typical brain abnormalities were considered as evidence for DIS, while also assuming that the AQP4-IgG status was unknown, the median time to diagnosis using the 2015 diagnosis criteria for NMOSD was shortened from 28 months to 6 months (p = 0.008). Asymptomatic acute NMOSD-typical brain lesions can be accompanied by an acute attack of ON or myelitis. Identifying these asymptomatic brain lesions may help facilitate earlier diagnosis of NMOSD.

    The aim of this study was to establish the natural course of unrevised asymptomatic pseudotumours after metal-on-metal (MoM) hip resurfacing during a six- to 12-month follow-up period. We used repeated metal artefact reduction sequence (MARS)-magnetic resonance imaging (MRI), serum metal ion analysis and clinical examination to study 14 unrevised hips (mean patient age 52.7 years, 46 to 68, 5 female, 7 male) with a pseudotumour and 23 hips (mean patient age 52.8 years, 38 to 69, 7 female, 16 male) without a pseudotumour. The mean post-operative time to the first MARS-MRI scan was 4.3 years (2.2 to 8.3), and mean time between the first and second MARS-MRI scan was eight months (6 to 12). At the second MRI scan, the grade of severity of the pseudotumour had not changed in 35 hips. One new pseudotumour (Anderson C2 score, moderate) was observed, and one pseudotumour was downgraded from C2 (moderate) to C1 (mild). In general, the characteristics of the pseudotumours hardly changed. Repeated MARS-MRI scans within one year in patients with asymptomatic pseudotumours after MoM hip resurfacing showed little or no variation. In 23 patients without pseudotumour, one new asymptomatic pseudotumour was detected. This is the first longitudinal study on the natural history of pseudotumours using MARS-MRI scans in hip resurfacing, and mirrors recent results for 28 mm diameter MoM total hip replacement.

    Objective Asymptomatic erosive esophagitis (AEE) is commonly found in men, and might be a risk factor of developing esophageal adenocarcinoma. We aimed to determine if specific dietary habits increase the risk of AEE in asymptomatic Taiwanese men. Methods We recruited male adults undergoing upper gastrointestinal endoscopy for health check. We excluded subjects with reflux symptoms, or taking anti-reflux medications or drugs that potentially impair lower esophageal sphincter function or cause mucosal injury. The frequency of consuming reflux-provoking diets including alcohol, tea, coffee, tomato/citric juice, chocolate, sweet food, and spicy food was assessed. The erosive esophagitis was diagnosed based on the Los Angeles Classification after endoscopy. Frequent consumption of a specific diet was defined as ≥4 days/week of consuming that diet. Results A total of 1256 participants were recruited. After excluding 424 ineligible subjects, AEE was identified in 180 (22%) among 832 asymptomatic subjects. The risk of AEE increased with the number of days per week of consuming alcohol or tea: nondrinkers (19%, 17%), occasional drinkers (<1 day/week; 19%, 15%), regular drinkers (1–3 days/week; 26%, 21%), frequent drinkers (4–6 days/week; 32%, 22%), and daily drinkers (42%, 28%), respectively (trend test P < 0.001 for both). Multivariate analysis showed that hiatus hernia (adjusted odds ratio (aOR) 5.0, 95% confidence interval (CI) 2.6–9.6), drinking alcohol ≥4 days/week (aOR 2.3, 95% CI 1.3–4.0), and drinking tea ≥4 days/week (aOR 1.6, 95% CI 1.1–2.3) are independent risk factors of AEE. The risk of AEE was 3.8 times greater for those drinking both alcohol and tea ≥4 days/week than the non-drinkers. Conclusions Frequent alcohol and tea consumption increased the risk of AEE in Taiwanese men. PMID:28264069

    Full Text Available BACKGROUND: Asymptomatic malaria infection in refugees is both a threat to the lives of the individuals and the public in the host country. Although South Africa has been experiencing an unprecedented influx of refugees since 1994, data on malaria infection among refugees is lacking. Such information is critical since South Africa is among the countries that have planned to eliminate malaria. The objective of this study was to determine prevalence of asymptomatic malaria infection among a refugee population living in a city of KwaZulu-Natal province, South Africa. METHODS AND FINDINGS: A survey was conducted on adult refugee participants who attended a faith-based facility offering social services in a city of KwaZulu-Natal province, South Africa. The participants were screened for the presence of malaria using rapid diagnostic tests and microscopy. Demographic data for the participants were obtained using a closed ended questionnaire. Data was obtained for 303 participants consisting of 51.5% females and 47.5% males, ranging from 19 to 64 years old. More than 95% of them originated from sub-Saharan African countries. Two hundred and ninety participants provided a blood sample for screening of malaria. Of these, 3.8% tested positive for rapid diagnostic test and 5.9% for microscopy. The majority of malaria infections were due to Plasmodium falciparum. CONCLUSIONS: The study confirms the presence of asymptomatic malaria infections among a refugee population residing in a city of KwaZulu-Natal province that is not endemic for malaria. The results have important implications for both public health and malaria control in South Africa, particularly since the country has decided to eliminate malaria by 2018. To achieve this goal, South Africa needs to expand research, surveillance and elimination activities to include non-endemic areas, particularly with high refugee populations. We further recommend use of powerful diagnostic tests such as PCR for

    The application of high-throughput sequencing methods has raised doubt in the concept of the uniform healthy vaginal microbiota consisting predominantly of lactobacilli by revealing the existence of more variable bacterial community composition. As this needs to be analyzed more extensively and there is little straightforward data regarding the vaginal mycobiome of asymptomatic women we aimed to define bacterial and fungal communities in vaginal samples from 494 asymptomatic, reproductive-age Estonian women. The composition of the vaginal microbiota was determined by amplifying bacterial 16S rRNA and fungal internal transcribed spacer-1 (ITS-1) regions and subsequently sequencing them using 454 Life Sciences pyrosequencing. We delineated five major bacterial community groups with distinctive diversity and species composition. Lactobacilli were among the most abundant bacteria in all groups, but also members of genus Gardnerella had high relative abundance in some of the groups. Microbial diversity increased with higher vaginal pH values, and was also higher when a malodorous discharge was present, indicating that some of the women who consider themselves healthy may potentially have asymptomatic bacterial vaginosis (BV). Our study is the first of its kind to analyze the mycobiome that colonizes the healthy vaginal environment using barcoded pyrosequencing technology. We observed 196 fungal operational taxonomic units (OTUs), including 16 OTUs of Candida spp., which is more diverse than previously recognized. However, assessing true fungal diversity was complicated because of the problems regarding the possible air-borne contamination and bioinformatics used for identification of fungal taxons as significant proportion of fungal sequences were assigned to unspecified OTUs.

    Phenotypic and genetic characteristics of Shigella spp. isolated from diarrhoeal and asymptomatic children aged up to 5 years were analysed in this study. In total, 91 and 17 isolates were identified from diarrhoeal (case) and asymptomatic (control) children, respectively. All the isolates were tested for antimicrobial resistance, the presence of integrons, plasmid-mediated quinolone resistance (PMQR), virulence-associated genes and Shigella pathogenicity island (SH-PAI). The majority of the Shigella spp. from cases (68.1%) and controls (82.3%) were found to be resistant to fluoroquinolones. Integron carriage was detected more in cases (76.9%) than in controls (35.5%). Atypical class 1 integron was detected exclusively in Shigella flexneri from cases but not from the controls. PMQR genes such as aac(6')-Ib-cr and qnrS1 were detected in 82.4 and 14.3% of the isolates from cases and in 53 and 17.6% in controls, respectively. Shigella isolates from cases as well as from controls were positive for the invasive plasmid antigen H-encoding gene ipaH. The other virulence genes such as virF, sat, setA, setB, sen and ial were detected in Shigella isolates in 80.2, 49.4, 27.4, 27.4, 80.2 and 79.1% of cases and in 64.7, 52.9, 17.6, 17.6, 64.7 and 64.7% of controls, respectively. The entire SH-PAI was detected in S. flexneri serotype 2a from cases and controls. In an isolate from a control child, the SH-PAI was truncated. Integrons, PMQR and virulence-encoding genes were detected more frequently in cases than in controls. In diarrhoea endemic areas, asymptomatic carriers may play a crucial role in the transmission of multidrug-resistant Shigella spp. with all the putative virulence genes.

    Objectives Symptomatic neurological complications (NC) are a major cause of mortality in infective endocarditis (IE) but the impact of asymptomatic complications is unknown. We aimed to assess the impact of asymptomatic NC (AsNC) on the management and prognosis of IE. Methods From the database of cases collected for a population-based study on IE, we selected 283 patients with definite left-sided IE who had undergone at least one neuroimaging procedure (cerebral CT scan and/or MRI) performed as part of initial evaluation. Results Among those 283 patients, 100 had symptomatic neurological complications (SNC) prior to the investigation, 35 had an asymptomatic neurological complications (AsNC), and 148 had a normal cerebral imaging (NoNC). The rate of valve surgery was 43% in the 100 patients with SNC, 77% in the 35 with AsNC, and 54% in the 148 with NoNC (p<0.001). In-hospital mortality was 42% in patients with SNC, 8.6% in patients with AsNC, and 16.9% in patients with NoNC (p<0.001). Among the 135 patients with NC, 95 had an indication for valve surgery (71%), which was performed in 70 of them (mortality 20%) and not performed in 25 (mortality 68%). In a multivariate adjusted analysis of the 135 patients with NC, age, renal failure, septic shock, and IE caused by S. aureus were independently associated with in-hospital and 1-year mortality. In addition SNC was an independent predictor of 1-year mortality. Conclusions The presence of NC was associated with a poorer prognosis when symptomatic. Patients with AsNC had the highest rate of valve surgery and the lowest mortality rate, which suggests a protective role of surgery guided by systematic neuroimaging results. PMID:27400273

    Study Design Cross-sectional study. Objective Sacropelvic parameters in various spine and hip disorders have been published in various studies. We aimed to study the normal sacropelvic parameters and curvatures of the spine and their correlation in asymptomatic Indian adults in relation to variations in sex and age. Methods The study included 101 asymptomatic adults (50 men and 51 women with an average age of 47.16 and 48.59 years, respectively). For each subject, the thoracic kyphosis (TK), lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), and sacral slope (SS) were measured from standing lateral radiographs. After stratification of the group by sex and age with a cutoff of 50 years, descriptive, correlation, and regression analysis were performed using SPSS software. Results The average PI, SS, PT, LL, and TK values were 55.48 (±5.31), 35.99 (±7.53), 17.97 (±7.16), 48.84 (±9.82), and 32.55 (±10.92), respectively. No statistically significant difference was observed in these values with regards to sex and age  50 years but the pelvic incidence was found to be higher in women. A positive correlation between the PI and SS and a negative correlation between the SS and PT was observed. A positive correlation between the TK and LL was found in subjects > 50 years. Simple and multiple regression analyses were also performed for different groups. Conclusion The current study is the first of asymptomatic Indian adults and provides invaluable information to the clinicians about the normal range of sacropelvic and spinopelvic parameters, which is useful to plan spinal deformity corrections and to evaluate pathologic conditions associated with abnormal angular values.

    Full Text Available BACKGROUND: Although several studies suggest that genetic factors are associated with human UTI susceptibility, the role of DNA variation in regulating early in vivo urine inflammatory responses has not been fully examined. We examined whether candidate gene polymorphisms were associated with altered urine inflammatory profiles in asymptomatic women with or without bacteriuria. METHODOLOGY: We conducted a cross-sectional analysis of asymptomatic bacteriuria (ASB in 1,261 asymptomatic women ages 18-49 years originally enrolled as participants in a population-based case-control study of recurrent UTI and pyelonephritis. We genotyped polymorphisms in CXCR1, CXCR2, TLR1, TLR2, TLR4, TLR5, and TIRAP in women with and without ASB. We collected urine samples and measured levels of uropathogenic bacteria, neutrophils, and chemokines. PRINCIPAL FINDINGS: Polymorphism TLR2_G2258A, a variant associated with decreased lipopeptide-induced signaling, was associated with increased ASB risk (odds ratio 3.44, 95%CI; 1.65-7.17. Three CXCR1 polymorphisms were associated with ASB caused by gram-positive organisms. ASB was associated with urinary CXCL-8 levels, but not CXCL-5, CXCL-6, or sICAM-1 (P< or =0.0001. Urinary levels of CXCL-8 and CXCL-6, but not ICAM-1, were associated with higher neutrophil levels (P< or =0.0001. In addition, polymorphism CXCR1_G827C was associated with increased CXCL-8 levels in women with ASB (P = 0.004. CONCLUSIONS: TLR2 and CXCR1 polymorphisms were associated with ASB and a CXCR1 variant was associated with urine CXCL-8 levels. These results suggest that genetic factors are associated with early in vivo human bladder immune responses prior to the development of symptomatic UTIs.

    To evaluate the MRI findings in the lumbar spines of asymptomatic elite junior tennis players. The lumbar spine MRI studies of 98 asymptomatic junior elite tennis players (51 male, 47 female) with a mean age of 18 years (age range 11.2-26.3 years; standard deviation 3.1) was reviewed by two consultant musculoskeletal radiologists using consensus opinion. Images were assessed using accepted classification systems. Four players (4 %) had no abnormality. Facet joint arthropathy occurred in 89.7 % of the players, being mild in 84.5 % of cases. There were 41 synovial cysts in 22.4 % of the cohort all occurring in the presence of facet arthropathy. Disc degeneration was noted in 62.2 % of players, being mild in 76.2 % of those affected. Disc herniation was noted in 30.6 % of players, with 86.1 % of these being broad based and 13.9 % being focal. There was nerve root compression in 2 %. There were 41 pars interarticularis abnormalities in 29.6 % of patients, 63.4 % of these being grades 1-3. There was grade 1 spondylolisthesis in 5.1 % of players. The prevalence of facet joint arthropathy, disc degeneration, disc herniation and pars interarticularis fracture was lower in female players than in male and lower in the under 16-year-olds compared with the over 20-year-olds. There is a significant amount of underlying pathology that would normally go undetected in this group of asymptomatic elite athletes. Whilst these findings cannot be detected clinically, their relevance is in facilitating appropriate prehabilitation to prevent loss of playing time and potentially career-ending injuries. (orig.)

    The interleukin (IL)-12 family, composed of heterodimeric cytokines including IL-12 (formed by IL-12p35 and IL-12p40 subunits), IL-23 (formed by IL-23p19 and IL-12p40 subunits), IL-27 (formed by IL-27p28 and EBI3 subunits) and IL-35 (formed by IL-12p35 and EBI3 subunits), establishes a link between innate and adaptive immunity that involves different immune effector cells and cytokines to tumors. However, the role of IL-12 family in breast cancer (BC) progression and prognosis remains unclear. In the present study, we demonstrated evidence indicating that EBI3, IL-12p35 and IL-12p40 but not IL-23p19 or IL-27p28 were highly expressed in BC tissues, suggested that tumor derived EBI3, IL-12p35 and IL-12p40 were associated with tumor progression. Circulating IL-12 and IL-23 low expressed, but IL-27 and IL-35 high expressed in BC patients, especially circulating IL-23 associated with IL-35 to mediate BC tumor resection. Ki-67, p53 and EGFR expression on BC tissues, as well as CA125, CA153 and CA199 levels on BC bloods increased when circulating IL-23: IL-35 ratio decreased. Together, for the first time, our data suggest that circulating IL-23: IL-35 ratio may be an important indicator association with BC progression and prognosis. However, further research should be carried out to assess the implications of circulating IL-23: IL-35 ratio in a larger sample size.

    Full Text Available T-cell large granular lymphocyte (T-LGL leukemia represents a clonal proliferation of cytotoxic T-cells which etiology has not been entirely elucidated. However, CD4+, CD4–,CD8–, CD4+, CD8+ cases have been described. The disease is usually characterized by cytopenias and a modest lymphocytosis. The majority of patients with T-LGL leukemia remains asymptomatic for a long period and will require treatment later during the course of their disease. Hereby we describe a case of T-LGL leukemia diagnosed by flow cytometry, which presented indolent course and required no treatment so far.

    2005-01-01

    Colonoscopic diagnosis of asymptomatic early acute appendicitis is exceedingly rare. Although obstruction of the lumen due to various causes is believed to be the most common physiologic mechanism of acute appendicitis, all of the previously documented cases in the literature have only shown a patent appendiceal lumen with pus flowing into the cecum. We present the case of a patient undergoing colonoscopy for colorectal cancer evaluation with no abdominal symptoms. An obstructed, swollen appendix was seen. The process was probably initiated during the colonoscopy, documenting perhaps the earliest stage of acute appendicitis for the first time. Endoscopic, CT and microscopic documentation of the case is also presented.

    VIANEY MARÍN-CEVADA

    Full Text Available ABSTRACT Pink disease is an asymptomatic pineapple disease in the field and is evidenced with a reddark coloration when the infected fruit is processed to obtain products such as juice, jam, and preservatives. Tatumella morbirosei and T. ptyseos (formerly Pantoea citrea have been demonstrated as causal agents. Although T. morbirosei and T. ptyseos have been well studied, there are currently no cost effective control methods in pineapple cultivation. The purpose of this review is to summarize the significant and updated research on the role of pink disease in pineapple.

    Cytauxzoon spp. DNA was detected for the first time in blood samples from asymptomatic Brazilian wild captive felids. In 2006, 72 EDTA blood samples from seven wild felids species: Puma concolor (puma), Leopardus pardalis (ocelot), Puma yagouaroundi (jaguarundi), Leopardus wiedii (margay), Leopardus tigrinus (little spotted cat), Oncifelis colocolo (pampas cat) and Panthera onca (jaguar) were analyzed using polymerase chain reaction to amplify the 18S rRNA gene segment in order to verify the presence of Cytauxzoon spp. DNA. Nine samples were positive: six ocelots, two pumas, and one jaguar. In Brazil, wild felids may be natural reservoirs for Cytauxzoon spp.

    The congenital intrapericardial hernia is a rare kind of diaphragmatic hernia. It is due to an embryologic defect of the central tendon of the diaphragm, often accompanied by other congenital malformations. This work presents a unique case report in the literature of the congenital association between intrapericardial diaphragmatic hernia and epigastric hernia in an adult woman. In spite of herniation of the colon and omentum the patient was completely asymptomatic, requesting surgery for an epigastric hernia for aesthetic reasons. The defect of the diaphragm was sutured and the abdominal wall was repaired with a prosthetic mesh.

    Diagnosis of Wilson's disease (WD) still remains a challenge since no single test has an accuracy of 100%. Molecular testing for ATP7B gene mutations can help reach the diagnosis when routine testing is equivocal. We herein report an asymptomatic WD patient diagnosed accidentally by genetic analysis. Th is case suggests that WD is a challenge even in particular contexts such as family screening. Genetic testing of ATP7B gene should be recommended in the family members of WD patients with minimal alterations of specific tests such as ceruloplasmin, and presence of steatosis or increased body mass index.

    Escherichia coli is the most common organism associated with asymptomatic bacteriuria (ABU) in humans. In contrast to uropathogenic E. coli (UPEC) that cause symptomatic urinary tract infection, very little is known about the mechanisms by which these strains colonize the urinary tract. Here, we...... have investigated the biofilm-forming capacity on abiotic surfaces of groups of ABU strains and UPEC strains in human urine. We found that there is a strong bias; ABU strains were significantly better biofilm formers than UPEC strains. Our data suggest that biofilm formation in urinary tract infectious...

    QT prolongation on resting electrocardiography (ECG) is common, and the clinician is often challenged by the dilemma of excluding acquired causes and recognizing potential congenital long QT syndrome (LQTS). The hallmark of LQTS is an abnormally long QT interval. However, a normal or borderline long QT interval may be observed in up to 50% of patients with LQTS because of the intermittent nature of QT prolongation. This review presents an approach to evaluating the asymptomatic patient with a borderline long QT interval, which incorporates a comprehensive clinical assessment, rest and provocative ECG testing, and genetic testing when appropriate.

    The authors have analyzed the cases of diagnosis of asymptomatic tumors of the parathyroid gland made during 8814 operations on the thyroid in the period from 1995 through 2004. The probability of detecting parathyroid incidentalomas in different forms of goiter was calculated which reaches 0.4%. A precision technique of operating allows the parathyroid tumors to be detected at the preclinical stage in all patients apart from a removal of the necessary volume of the thyroid tissue, guaranteed preservation of the laryngeal nerves and parathyroid glands.

  7. Massive gastrointestinal bleeding:An unusual case of asymptomatic extrarenal,visceral,fibromuscular dysplasia

    2007-01-01

    Extrarenal fibromuscular dysplasia causing gastrointestinal bleeding without other manifestations and especially sparing renal vasculature is uncommon. The diagnosis of this entity is usually made by radiographic appearance and the treatment is controversial. To our knowledge only seven cases of visceral fibromuscular dysplasia as a primary manifestation of the disease have been described, symptoms range from abdominal pain to gangrene. This is the first case of visceral fibromuscular dysplasia presenting with otherwise asymptomatic gastrointestinal bleeding, without bowel necrosis or ischemic changes. We provide a review of the literature.

    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.

    The presence of Chlamydia trachomatis antigen was examined in 400 endocervical samples collected from an equal number of asymptomatic sexually active women. The overall prevalence was found to be 4%, using the enzyme-linked immunosorbent assay. Chlamydia infection was correlated with younger age (5.8%, p 0.05), condom (0%, p Chlamydia trachomatis infection is associated with younger age, intense sexual life, and use of oral contraceptives. Given that the majority of infected women revealed cervical pathology, the detection of chlamydia in the high-risk female population with cervical changes seems to be essential.

    Sarcina ventriculi is a gram-positive coccus that grows in a tetrad arrangement in the stomach. In the past 35 years, less than 20 cases have been reported in the literature, and it has been associated with life-threatening complications such as emphysematous gastritis and perforation. Treatment of S ventriculi generally consists of proton pump inhibitors with or without adjuvant antibiotic therapy. We report the first ever case of S ventriculi, including the morphological and immunohistochemical features, occurring in an asymptomatic patient with a history of Helicobacter pylori gastric ulcers.

    Full Text Available Infection with genital herpes simplex virus (HSV remains a common viral sexually transmitted disease, often subclinical and a major worldwide problem of women of reproductive age group. Herpes cervicitis is an unusual presentation of Herpes simplex virus infection in females. The finding of herpes cervicitis on routine pap smear of an asymptomatic woman on Intrauterine contraceptive device still further supports the need for increased awareness on the possibility of Herpes simplex virus infection among women, particularly those on Intrauterine contraceptive device. The index case is a 28 years old Nigerian female who was referred to our Special Treatment Clinic on account of an abnormal pap smear cytology which was in keeping with Herpes cervicitis. There was no history of genital ulcer in this patient; however ELISA for HSV 2 IgM was positive in her. We therefore describe a case of herpes cervicitis in an asymptomatic woman on intrauterine contraceptive device. This case highlights to clinicians the need to be aware of the possibility of this association and to carry out relevant investigations so as to identify and treat these patients appropriately. Therefore, there is a need to put in place adequate public health intervention strategy to prevent genital herpes in women of reproductive age group with a view to preventing the possibility of congenital herpes in subsequent pregnancy.

    The aim of this study was to analyse factors indicating prophylactic removal of impacted lower third molars, and how they, and possibly surgeon experience, influence the therapeutic decision-making process. A descriptive observational study was made of 40 asymptomatic impacted lower third molars. Orthopantomographs were scanned and presented to four professionals with different degrees of surgical experience. The examiners received information relating to patient age and sex, molar inclination and degree of impaction, and expressed their opinion on the necessity for teeth removal. There was a statistically significant relationship between examiner decision and the estimated probability of pathology if the molars were not removed (Pmolar, age, degree of impaction and patient sex. No statistically significant differences (P>0.05) were observed between residents and trainers in terms of the decision to remove or estimated risk of complications. The management approach adopted by oral surgeons regarding the removal of asymptomatic impacted lower third molars depends upon the perceived risk of complications if such teeth are not removed, other factors being secondary. The surgical experience of the professional does not seem to influence treatment decision.

    Full Text Available Abstract Background To report the rare association of peripheral retinal ischemia in a patient with Waldenström's macroglobulinemia. Case Presentation A 39-year old man with a recent diagnosis of asymptomatic Waldenström's macroglobulinemia (WM was referred from his physician for ocular evaluation. The fundus examination in his right eye (RE revealed very mild central vein dilation, while retinal hemorrhages associated with microaneurismal alterations of the vascular plexus were detected at the temporal periphery. Fluoroscein angiography of his RE revealed an extended area of capillary dropout distal to the microaneurismal lesions. In our patient with WM an extensive area of capillary non-perfusion, in the absence of severe involvement of the posterior pole was documented; this association to the best of our knowledge has never been reported before. Conclusion Although the incidence of the disease is rare, meticulous examination of the retinal periphery should be performed in all patients with WM and vice versa the differential diagnosis of peripheral retinal ischemia of unknown origin should include an investigation to rule out asymptomatic Waldenström's macroglobulinemia.

    Aims: To determine when a bone scan investigation is appropriate in asymptomatic men diagnosed with prostate cancer. Methods: Between November 2005 and July 2006, 317 men with prostate cancer underwent a bone scan study; 176 men fulfilled the inclusion criteria. Prostate-specific antigen (PSA) cut-offs as well as univariate and multivariate logistic regression analyses using digital rectal examination finding, biopsy Gleason scores and age were performed to determine when a bone scan study is likely to be of value. Results: Only 1/61 men (1.6%) with a serum PSA ≤ 20 ng/mL had a positive bone scan. However, 2/38 men (4.7%) with a serum PSA 20.1-40.0 ng/mL, 3/20 men (15%) with a serum PSA 40.1-60.0 ng/mL, 7/19 men (36.8%) with a serum PSA 60.1-100.0 ng/mL and 19/38 men (50%) with a serum PSA > 100.0 ng/mL had positive bone scans. Univariate and multivariate logistic regression analyses were uninformative in these groups. Conclusion: Based on our findings, a bone scan is of limited value in asymptomatic prostate cancer patients presenting PSA ≤ 20 ng/mL. Therefore, this investigation can be eliminated unless a curative treatment is contemplated. Furthermore, digital rectal examination finding, biopsy Gleason score and age are unhelpful in predicting those who might harbor bone metastasis.
