    Parfitt, Sheryl E; Bogat, Mary L; Roth, Cheryl

    Sepsis during pregnancy is one of the five leading causes of maternal mortality worldwide. Early recognition and prompt treatment of maternal sepsis is necessary to improve patient outcomes. Patient education on practices that reduce infections may be helpful in decreasing rates of sepsis. Education of nurses about early signs and symptoms of sepsis in pregnancy and use of obstetric-specific tools can assist in timely identification and better outcomes. Although the Surviving Sepsis Campaign (SSC) criteria for diagnosis of sepsis in the general population are not pertinent for obstetric patients, their treatment bundles (guidelines) are applicable and can be used to guide care of obstetric patients who develop sepsis.This article is the third in a series of three that discuss the importance of sepsis and septic shock in pregnancy. This article includes case studies, treatment, prognosis, education, and prevention of maternal sepsis.

    Diagnosis and prognosis are components of the Patient Client Management Model of the Guide to Physical Therapist Practice. The purpose of this study is to determine how pediatric physical therapists (PPTs) define and use diagnosis and prognosis in their practice. This article reports the themes revealed in answers to open-ended questions on diagnosis and prognosis (n = 7 to n = 68) in an electronic survey that was sent to PPTs who are members of the American Physical Therapy Association (APTA) Section on Pediatrics, and non-Section members of the APTA who identify themselves as PPTs. In this sample, PPTs lack consistency in their definition and use of the terms diagnosis and prognosis. Many respondents reported a level of discomfort with the relevance, utility, and usefulness of diagnosis and prognosis. Despite literature on diagnosis and prognosis, PPTs continue to struggle with using these concepts in their practice.

Most cases of POH are caused by heterozygous inactivating mutations of GNAS, the gene encoding the alpha subunit of the G-stimulatory protein of adenylyl cyclase. POH is part of a spectrum of related genetic disorders, including Albright hereditary osteodystrophy, pseudohypoparathyroidism, and primary osteoma cutis, that share common features of superficial ossification and association with inactivating mutations of GNAS. The genetics, diagnostic criteria, supporting clinical features, current management, and prognosis of POH are reviewed here, and emerging therapeutic strategies are discussed.

    To assess bilateral breast cancer patients, initially diagnosed with stage II unilateral breast cancer. 113 patients with stage 0-II breast cancer diagnosed between 1983 and 2011 were assessed. Of these, 8 patients had bilateral breast cancer: 7 patients with metachronous bilateral breast cancer and 1 patient with synchronous breast cancer. Breast ultrasound, mammography, computed tomography and magnetic resonance imaging were used to diagnose recurrence, loco regional and distant metastasis. Age at diagnosis ranged from 37 to 59 years, with a maximum age incidence in the 4th decade (age between: 31-40 years). The average time interval between the two breast cancers was 8.125 years. The most common histological type was invasive ductal carcinoma. All eight patients with bilateral breast cancer had at least one type of recurrence/metastasis, mostly in the liver, and statistically the pleuropulmonary and liver metastases were the most frequent causes of death. Patients in the 4th decade diagnosed with unilateral breast cancer are at risk of developing bilateral breast cancer. In metachronous breast cancer, the time interval between the detection of the second breast cancer and death is directly proportional to the time interval between the two breast cancers.

    To the clinician, alcoholism can appear as an amorphous entity that is confusing with respect to diagnosis, treatment prognosis, and the role of the health professional, despite its high incidence and associated morbidities and mortality when unrecognized or untreated. This chapter focuses on the clinical application of current knowledge, with the aim of being useful to the practitioner in working directly with patients for whom alcoholism may or may not be an already identified problem. It briefly reviews large-scale studies and then focuses on diagnosis and prognosis assessment and decision making. Also considered are current controversies in nomenclature and the chapter ends with an economic perspective with respect to healthcare and cost to society. As the introductory chapter, the goal is to provide a context of the scope of alcoholism and attendant problems for the rest of the chapters. © 2014 Elsevier B.V. All rights reserved.

  13. Saliva as a tool for oral cancer diagnosis and prognosis.

    Science.gov (United States)

    Nagler, Rafael M

    2009-12-01

    Saliva testing, a non-invasive alternative to serum testing, may be an effective modality for diagnosis and for prognosis prediction of oral cancer, as well as for monitoring post therapy status, by measuring specific salivary macromolecules, examining proteomic or genomic targets such as enzymes, cytokines, growth factors, metalloproteinases, endothelin, telomerase, cytokeratines, mRNA's and DNA transcripts. Salivary analysis has been shown to be a useful diagnostic tool also for distant malignancies such as breast cancer. In recent years, significant alterations have been demonstrated in the saliva of oral cancer patients in the epithelial tumor markers--Cyfra 21-1, TPS and CA12, various oxidative stress-related salivary parameters as ROS and RNS, biochemical and immunological parameters as IGF and MMP's and RNA transcripts of IL8, IL-1B, DUSP1, HA3, OAZ1, S100P, and SAT. Collectively these accumulated data are predicted to alter the field of oral cancer diagnosis by employing highly sensitive new tools which will enable both medical professionals and the patients themselves to monitor their saliva for diagnosis and prognosis prediction, as they relate to oral cancer. At this point however, the aim of salivary analysis is mainly for screening which may be helpful in the future.

    Delirium is a common acute neuropsychiatric syndrome. It is characterized by concurrent disturbances of consciousness and attention, perception, reasoning, memory, emotionality, the sleep-wake cycle as well as psychomotor symptoms. Delirium caused by alcohol or medication withdrawal is not the subject of the current review. Specific predisposing and precipitating factors have been identified in delirium which converge in a common final pathway of global brain dysfunction. The major predisposing factors are older age, cognitive impairment or dementia, sensory deficits, multimorbidity and polypharmacy. Delirium is always caused by one or more underlying pathologies which need to be identified. In neurology both primary triggers of delirium, such as stroke or epileptic seizures and also secondary triggers, such as metabolic factors or medication side effects play a major role. Nonpharmacological interventions are important in the prevention of delirium and lead to an improvement in prognosis. Delirium is associated with increased mortality and in the long term the development of cognitive deficits and functional impairment.

    Full Text Available Acute kidney injury (AKI is a common problem highly associated with hospitalisation. AKI is the cause of harmful short-term consequences: longer hospital stays, greater disability after discharge, and greater risk of in-hospital mortality, as well as adverse long-term outcomes, such as progression to chronic kidney disease, development of cardiovascular disease, and increased risk of long-term mortality. The concept of AKI has changed since the introduction of the ‘Risk, Injury, Failure, Loss of kidney function, End-stage kidney disease’ (RIFLE classification. More recently, the ‘Kidney Disease Improving Global Outcomes’ (KDIGO classification appears to have provided increased diagnostic sensitivity and outcome-prediction capability. Novel biomarkers and further research on the role of the immune system in AKI may help improve the diagnosis, severity, outcome evaluation, and treatment of the condition. In this review we describe the epidemiology, diagnosis, and prognosis of AKI, as well as possible future directions for its clinical management.

    2007-01-01

    In antiquity the visual examination of urine (uroscopy) is well documented. Uroscopy gradually evolved from a prognostic indicator to a diagnostic tool. Comparison of the uses of uroscopy by Hippocrates (400 BC) and Theophilus (700 AD) illustrates this transformation. We reviewed medical and historical literature as well as the translated works of Hippocrates. Although Hippocrates was one of the first physicians to use urine to interpret human body functioning, urine was mainly used as a means for prognosis and prediction of outcomes of illness. In his text De Urinis Theophilus introduced an innovative doctrine and used uroscopy for diagnosis of illnesses. In this respect uroscopy became a paradigm for later diagnostic strategies and is considered an important milestone in the history of clinical diagnosis. Hippocrates' writings displayed uroscopy used in examination of illness. However, he considered it in the context for accurate prognoses. Theophilus treated uroscopy in a sophisticated objective manner and attempted to use uroscopy in an orderly, systemic method to accurately diagnose illness. It was through these approaches to uroscopy that Theophilus became one of the physicians who contributed to the birth of medieval medical studies.

    Full Text Available Laura D Garrett Department of Veterinary Clinical Medicine, University of Illinois College of Veterinary Medicine, Urbana, IL, USA Abstract: Mast cell tumors (MCTs are the most common malignant skin cancer in dogs, and significant variability exists in their biological behavior. Most MCTs are cured with appropriate local therapy, but a subset shows malignant behavior with the potential to spread to lymph nodes, liver, spleen, and other areas and to thus become a systemic cancer. Because of this variable behavior, it is difficult to predict how any individual tumor is going to behave. The variability thus creates uncertainty in deciding what a particular dog's prognosis is, whether staging tests to assess for metastasis are needed, and even what treatments will be necessary for best outcome. In addition to controversies over the potential for development of systemic disease, or diffuse metastasis, controversies also exist over what treatment is needed to best attain local control of these tumors. This article will briefly discuss the diagnosis of MCTs in dogs and will summarize the literature in regards to the controversial topics surrounding the more aggressive form of this disease, with recommendations made based on published studies. Keywords: mitotic index, mastocytosis, tyrosine kinase inhibitor, histologic grade

    2013-11-01

    Obesity combined with breast cancer is a public health problem, given the high incidence and prevalence of both diseases. The aim of this review is to determine the current status of research on the relationship between the body weight of breast cancer patients and their prognosis. Overweight and obesity at the time of diagnosis are associated with a worse prognosis in breast cancer survivors. Observational studies show that breast cancer mortality is 33% higher in obese than in non-obese survivors. Furthermore, weight gain after diagnosis is common in these patients and is even greater in those receiving chemotherapy. Weight gains of 2-8 kg are observed in 68% of patients 3 years after diagnosis. Each 5 kg increase in body weight is associated with a 13% increase in breast cancer specific mortality. The mechanisms that cause this weight gain are not totally known. A higher weight gain is also associated with higher the risk of co-morbid cardiometabolic diseases, which worsen the quality of life and shorten overall survival. On the other hand, excess adipose tissue is an indirect promoter of tumor cell proliferation and releases circulating estrogens. Hence, preventing excess weight is important in these patients. An important limitation is the small number of randomised controlled trials investigating the type of diet that could be recommended specifically to breast cancer survivors. The evidence from current studies suggests that a healthy diet, low in fat and simple sugars and with a high proportion of fruit, vegetables and wholegrain products, has the potential to reduce morbidity and the risk of recurrence significantly, thus improving prognosis and quality of life in the long term.

    2011-01-01

    Monoclonal gammopathy of unknown significance (MGUS) as one of the most common premalignant disorders and smoldering multiple myeloma (sMM) are both caused by a proliferation of monoclonal plasma cells leading to a detectable serum monoclonal protein and/or excess of plasma cells in the bone marrow. Prerequisite for the diagnosis is that plasma cell disease does not cause clinical symptoms. Cytogenetic aberrations are detectable in the majority of patient in the clonally expanded plasma cells. MGUS consistently proceeds symptomatic MM. The lifetime risk of progression into symptomatic multiple myeloma lies between 15% and 59% for patients with MGUS or sMM. Prognostic parameters for development of symptomatic multiple myeloma from MGUS or sMM are concentration of monoclonal protein, bone marrow plasmocytosis, a non- IgG subtype and an abnormal free-light chain ratio. Detection of more than 1 focal lesion in whole body MRI, 95% or more of bone marrow plasma cells displaying an aberrant phenotype in flow cytometry and an evolving clinical course in two consecutive follow-up visits are additional prognostic parameters for sMM. Currently there is no accepted secondary prevention strategy available for sMM and MGUS progression. Future studies are required to combine increasing knowledge on risk factors and molecular pathogenesis with targeted agents to prevent progression.

  2. Breaking bad news: Effects of forecasting diagnosis and framing prognosis.

    Science.gov (United States)

    Porensky, Emily K; Carpenter, Brian D

    2016-01-01

    Research to support guidelines for breaking bad news is lacking. This study used an experimental paradigm to test two communication strategies, forecasting bad news and framing prognosis, in the context of cancer. In a 2×2 design, 128 participants received bad news in a hypothetical consultation. A videotaped physician presented diagnostic and prognostic information, varying warning (warning shot vs. no warning), and framing (positive vs. negative). Effects on psychological distress, recall accuracy, and subjective interpretations of the news were assessed. Warning was not associated with lower psychological distress or improved recall. Individuals who heard a positively-framed prognosis had significantly less psychological distress, rated their prognosis better, and were more hopeful than those who heard a negatively-framed prognosis. However, they also showed a trend toward reduced accuracy in recalling prognostic statistics. Results contribute to a growing body of literature exploring optimal approaches for communicating bad news in health care. Although research in clinical settings is needed to bolster results, findings suggest that when providers use positive framing to reduce distress about prognosis, they should also consider ways to overcome potential reductions in recall accuracy, such as repeating statistical information or supplementing with written information.

    The year 2001 saw unveiling of anatomy of the human genome with sequencing of 90% of the euchromatic region. But the ultimate goal of the Human Genome Project to delineate the positions of all genes is yet to be achieved. In Situ Hybridization (ISH) is one of the methods that help in localizing genes on chromosomes. The present study aimed to use radioactive- and fluorescent-labeled probes for screening various congenital anomalies (sex chromosomal and autosomal), for prenatal diagnosis and cancer genetics. Standard techniques were used for hybridization with radioactively and fluorescent labeled probes. Sex chromosome aneuploidies (XXY, XO, XXX, XYY etc.) were analyzed using centromeric probes for chromosomes X and Y. The cases with ambiguous genitalia were further analyzed using probe specific for the sex-determining region (SRY) on the Y chromosome. Suspected cases of Down syndrome were analyzed using probe specific for centromeric region of chromosome 21 to confirm trisomy 21. Prenatal diagnosis included screening aneuploidies of chromosomes 13, 18, 21, X and Y on uncultured cells and metaphases obtained from amniotic fluid and chorionic villi samplings. Gene alterations were also studied in Retinoblastoma patients, Chronic Myeloid Leukemia (CML) and Acute Promyelocytic Leukemia (APML) using probes specific for Rb1, bcr/abl and PML/RARα genes respectively. Response to therapy was assessed by evaluating minimal residual disease (MRD) in leukemia patients. Attempts were also made to analyze cells obtained from buccal mucosa and bladder epithelium that could facilitate rapid screening of sex chromosome anomalies and bladder cancer without painful invasive techniques. Prenatal diagnosis using ISH on uncultured cells could provide an accurate and rapid result. These results of prenatal diagnosis were in conformation with results of conventional cytogenetics obtained after long-term cultures. Molecular rearrangements that could not be detected with conventional

    Alzheimer's disease (AD) is a neurodegenerative disease that inhibits cognitive functions and has no cure. This report reviews the current diagnostic standards for AD with an emphasis on early diagnosis using the cerebrospinal fluid (CSF) biomarkers amyloid-beta, t-tau, and p-tau and fluorodeoxyglucose positron emission tomography imaging. Abnormal levels of these CSF biomarkers and decreased cerebral uptake of glucose have recently been used in the early diagnosis of AD in experimental studies. These promising biomarkers can be measured using immunoassays performed in singleplex or multiplex formats. Although presently, there are no Food and Drug Administration-approved in vitro diagnostics (IVDs) for early detection of AD, a multiplex immunoassay measuring a panel of promising AD biomarkers in CSF may be a likely IVD candidate for the clinical AD diagnostic market. Specifically, the INNO-BIA AlzBio3 immunoassay kit, performed using bead arrays on the xMAP Luminex analyzer, allows simultaneous quantification of amyloid-beta, t-tau, and p-tau biomarkers. AD biomarkers can also be screened using enzyme-linked immunosorbent assays that are offered as laboratory-developed tests. © 2014 Society for Laboratory Automation and Screening.

    Triple X syndrome is a relatively common sex chromosomal abnormality occurring in 0,1% of live-born female infants. Most of these infants have a normal phenotype and only a few cases with 47, XXX karyotype have congenital malformations. We report three cases of triple X syndrome that were diagnosed prenatally by genetic amniocentesis for advanced maternal age and have been observed from birth to age of 3 to 12 years. A description of their growth and development is presented. The birth weight was normal in all patients and one of them had facial dysmorphism with right microphtalmia and auricular septal defect. During the first 2 years of life, the neuromotor development of these infants was not distinguishable from chromosomally normal children. By 3 years of age, two patients have a moderate developmental delay in speech and language. One girl 12-year-old had normal schooling. The diagnosis of the triple X syndrome can be never made because clinical demonstrations are not rather important to arouse the demand of a karyotype. Prenatal diagnosis is often made in front of the advanced maternal age. Expectant parents must be counseled as to the significance of this 47, XXX karyotype and prognostic information must be given.

    Full Text Available Twin-twin transfusion syndrome is a serious complication of monozygotic, monochorionic, diamniotic twins resulting from transplacental vascular communications. In this syndrome blood is thought to be shunted from one twin - donor,who develops anaemia,growth retardation and oligoamnios, to the other twin - recipient,who becomes plethoric,macrosomic and develops polyhydroamnios. The incidence of twin-twin transfusion syndrome ranges from 5-15% of all twin pregnancies. If this condition develops in the second trimester, it is usually associated with spontaneous abortion and death of one or both fetuses before viability. Developing the syndrome in the third trimester has better perinatal outcome. Mortality rates ranging from 56%-100%, depending on gestational age and severity of the syndrome. The ultrasound criterias for diagnosis, in this study,were the presence of twins of the same sex with discordant growth, with oligohydroamnios in one twin sac and polyhydroamnios in the other one, one placenta and thin membrane between twins. The present study shows clinical course of 14 cases and value of Doppler ultrasound to analyze the usefulness of umbilical artery blood flow velocimetry for predicting the risk of twin-twin transfusion syndrome. 14 twin pregnancies with twin-twin transfusion syndrome were diagnosed during the last four years period and prospectivelly followed. 9 cases were diagnosed before the completion od 28 weeks of gestation.The mean gestational age was 21,6_+4,2 weeks at diagnosis and 23,2+_3,6 weeks at delivery. 5 cases were diagnosed after 28 weeks of gestation. The mean gestational age in this group was 29,6+_2,1 weeks at diagnosis and 33+_3,3 weeks at delivery. The survival rate in this study was 29%(8/28.9 cases ended in spontaneous abortion between 18th and 27th weeks of pregnancy (table 1 and 5 in premature labor (table 2.There were 7 intrauterine death (5 at admission and 2 few days after admission and 13 neonatal deaths

    The scheduled update to the German S3 guidelines on fibromyalgia syndrome (FMS) by the Association of the Scientific Medical Societies ("Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften", AWMF; registration number 041/004) was planned starting in March 2011. The development of the guidelines was coordinated by the German Interdisciplinary Association for Pain Therapy ("Deutsche Interdisziplinären Vereinigung für Schmerztherapie", DIVS), 9 scientific medical societies and 2 patient self-help organizations. Eight working groups with a total of 50 members were evenly balanced in terms of gender, medical field, potential conflicts of interest and hierarchical position in the medical and scientific fields. Literature searches were performed using the Medline, PsycInfo, Scopus and Cochrane Library databases (until December 2010). The grading of the strength of the evidence followed the scheme of the Oxford Centre for Evidence-Based Medicine. The formulation and grading of recommendations was accomplished using a multi-step, formal consensus process. The guidelines were reviewed by the boards of the participating scientific medical societies. The clinical diagnosis of FMS can be established by the American College of Rheumatology (ACR) 1990 classification criteria (with tender point examination), by the modified preliminary diagnostic ACR 2010 criteria or by the diagnostic criteria of the German interdisciplinary guideline (AWMF) on FMS.

    Metabolomics is a tool that has been used for the diagnosis and prognosis of specific diseases. The purpose of this study was to examine if metabolomics could be used as a potential diagnostic and prognostic tool for H1N1 pneumonia. Our hypothesis was that metabolomics can potentially be used early for the diagnosis and prognosis of H1N1 influenza pneumonia. 1 H nuclear magnetic resonance spectroscopy and gas chromatography-mass spectrometry were used to profile the metabolome in 42 patients with H1N1 pneumonia, 31 ventilated control subjects in the intensive care unit (ICU), and 30 culture-positive plasma samples from patients with bacterial community-acquired pneumonia drawn within the first 24 h of hospital admission for diagnosis and prognosis of disease. We found that plasma-based metabolomics from samples taken within 24 h of hospital admission can be used to discriminate H1N1 pneumonia from bacterial pneumonia and nonsurvivors from survivors of H1N1 pneumonia. Moreover, metabolomics is a highly sensitive and specific tool for the 90-day prognosis of mortality in H1N1 pneumonia. This study demonstrates that H1N1 pneumonia can create a quite different plasma metabolic profile from bacterial culture-positive pneumonia and ventilated control subjects in the ICU on the basis of plasma samples taken within 24 h of hospital/ICU admission, early in the course of disease.

    This research is seeking to develop a probabilistic framework for health diagnosis and prognosis of aging concrete structures in nuclear power plants that are subjected to physical, chemical, environment, and mechanical degradation. The proposed framework consists of four elements: monitoring, data analytics, uncertainty quantification, and prognosis. The current work focuses on degradation caused by ASR (alkali-silica reaction). Controlled concrete specimens with reactive aggregate are prepared to develop accelerated ASR degradation. Different monitoring techniques — infrared thermography, digital image correlation (DIC), mechanical deformation measurements, nonlinear impact resonance acoustic spectroscopy (NIRAS), and vibro-acoustic modulation (VAM) — are studied for ASR diagnosis of the specimens. Both DIC and mechanical measurements record the specimen deformation caused by ASR gel expansion. Thermography is used to compare the thermal response of pristine and damaged concrete specimens and generate a 2-D map of the damage (i.e., ASR gel and cracked area), thus facilitating localization and quantification of damage. NIRAS and VAM are two separate vibration-based techniques that detect nonlinear changes in dynamic properties caused by the damage. The diagnosis results from multiple techniques are then fused using a Bayesian network, which also helps to quantify the uncertainty in the diagnosis. Prognosis of ASR degradation is then performed based on the current state of degradation obtained from diagnosis, by using a coupled thermo-hydro-mechanical-chemical (THMC) model for ASR degradation. This comprehensive approach of monitoring, data analytics, and uncertainty-quantified diagnosis and prognosis will facilitate the development of a quantitative, risk informed framework that will support continuous assessment and risk management of structural health and performance.

    2011-11-01

    Full Text Available MicroRNAs (miRNAs are a class of non-coding small RNAs with critical regulatory functions as post-transcriptional regulators. Due to the fundamental importance and broad impact of miRNAs on multiple genes and pathways, dysregulated miRNAs have been associated with human diseases, including cancer. Colorectal cancer (CRC is among the most deadly diseases, and miRNAs offer a new frontier for target discovery and novel biomarkers for both diagnosis and prognosis. In this review, we summarize the recent advancement of miRNA research in CRC, in particular, the roles of miRNAs in colorectal cancer stem cells, EMT, chemoresistance, therapeutics, diagnosis and prognosis.

    An effective blood-based method for the diagnosis and prognosis of hepatocellular carcinoma (HCC) has not yet been developed. Circulating tumour DNA (ctDNA) carrying cancer-specific genetic and epigenetic aberrations may enable a noninvasive `liquid biopsy' for diagnosis and monitoring of cancer. Here, we identified an HCC-specific methylation marker panel by comparing HCC tissue and normal blood leukocytes and showed that methylation profiles of HCC tumour DNA and matched plasma ctDNA are highly correlated. Using cfDNA samples from a large cohort of 1,098 HCC patients and 835 normal controls, we constructed a diagnostic prediction model that showed high diagnostic specificity and sensitivity (P < 0.001) and was highly correlated with tumour burden, treatment response, and stage. Additionally, we constructed a prognostic prediction model that effectively predicted prognosis and survival (P < 0.001). Together, these findings demonstrate in a large clinical cohort the utility of ctDNA methylation markers in the diagnosis, surveillance, and prognosis of HCC.

  16. Fuzzy Evidential Network and Its Application as Medical Prognosis and Diagnosis Models.

    2017-08-01

    Uncertainty is one of the important facts of the medical knowledge. Medical prognosis and diagnosis, as the essential parts of medical knowledge, is affected by different aspects of uncertainty, which must be managed. In the previous studies, different theories such as Bayesian probability theory, evidence theory, and fuzzy set theory have been developed to represent and manage different aspects of uncertainty. Recently, hybrid frameworks are suggested to deal with various types of uncertainty in a single framework. Evidential networks are general frameworks for dealing explicitly with total and partial ignorance and offer powerful combination rule of contradictory evidence. In this framework, the fuzziness of linguistic variables is neglected while these variables commonly appear in the medical domain knowledge and different sources of medical information. In addition, the evidential network parameters are determined based on the experts' knowledge and no data-driven algorithm is provided to learn these parameters. In this study, a novel hybrid framework called fuzzy evidential network was suggested to manage the imprecision and epistemic uncertainty of medical prognosis and diagnosis. Also, a data-driven algorithm based on the fuzzy set theory and the fuzzy maximum likelihood is provided to learn the network parameters from clinical databases. The performance of the proposed framework as various prognosis and diagnosis models, compared with well-known machine learning algorithms and the results showed its superiority. Also, an evidential method is suggested to handle the missing values and its results were compared with KNN imputation method. Copyright © 2017 Elsevier Inc. All rights reserved.

    1990-01-01

    The objective of this study is to determine the discriminant accuracy of exercise thallium-201 myocardial perfusion scintigraphy for the diagnosis and prognosis of patients with known or suspected coronary artery disease. This is a survey of the National Library of Medicine MEDLINE database. The key medical subject headings used were coronary disease, myocardial infarction, radionuclide imaging, and thallium. A total of 122 retrieved studies were considered relevant and were reviewed in depth. Only studies reporting both the sensitivity and specificity of thallium scintigraphy were analyzed. Discriminant accuracy for diagnosis and prognosis was summarized in terms of pooled sensitivity and specificity. Exercise thallium scintigraphy is useful in the noninvasive diagnosis of coronary artery disease, especially in patients with abnormal resting electrocardiograms, restricted exercise tolerance, and intermediate probability of having disease at the time of testing as well as of defining the prognosis of patients with known or suspected coronary artery disease, especially in those with previous myocardial infarction. Because of various shortcomings in the published record, however, the marginal discriminant accuracy and cost effectiveness of thallium scintigraphy compared with conventional clinical assessment and exercise electrocardiography remain controversial. 193 references

  18. A Bayesian least squares support vector machines based framework for fault diagnosis and failure prognosis

    Science.gov (United States)

    Khawaja, Taimoor Saleem

    A high-belief low-overhead Prognostics and Health Management (PHM) system is desired for online real-time monitoring of complex non-linear systems operating in a complex (possibly non-Gaussian) noise environment. This thesis presents a Bayesian Least Squares Support Vector Machine (LS-SVM) based framework for fault diagnosis and failure prognosis in nonlinear non-Gaussian systems. The methodology assumes the availability of real-time process measurements, definition of a set of fault indicators and the existence of empirical knowledge (or historical data) to characterize both nominal and abnormal operating conditions. An efficient yet powerful Least Squares Support Vector Machine (LS-SVM) algorithm, set within a Bayesian Inference framework, not only allows for the development of real-time algorithms for diagnosis and prognosis but also provides a solid theoretical framework to address key concepts related to classification for diagnosis and regression modeling for prognosis. SVM machines are founded on the principle of Structural Risk Minimization (SRM) which tends to find a good trade-off between low empirical risk and small capacity. The key features in SVM are the use of non-linear kernels, the absence of local minima, the sparseness of the solution and the capacity control obtained by optimizing the margin. The Bayesian Inference framework linked with LS-SVMs allows a probabilistic interpretation of the results for diagnosis and prognosis. Additional levels of inference provide the much coveted features of adaptability and tunability of the modeling parameters. The two main modules considered in this research are fault diagnosis and failure prognosis. With the goal of designing an efficient and reliable fault diagnosis scheme, a novel Anomaly Detector is suggested based on the LS-SVM machines. The proposed scheme uses only baseline data to construct a 1-class LS-SVM machine which, when presented with online data is able to distinguish between normal behavior

    2016-06-01

    Because of the substantial increase in population ageing, age-related processes, such as dementia and Alzheimer disease (AD), are becoming highly prevalent. The course of this disease, including preprodromic phases, lasts at least 20 years. The presence of comorbidities, especially those of vascular origin, can trigger and aggravate disease progression. On the other hand, cognitive reserve, the absence or control of comorbid factors and healthy lifestyles can protect or modify -in the sense of slow down- disease progression. Knowledge of the phases of AD and their functional impact on affected individuals helps to identify the average prognosis and, in particular, to establish and predict care plans based on the individual's needs.

    2013-01-01

    Gastric cancer is an aggressive disease with nonspecific early symptoms. Its incidence and prognosis in young patients has shown considerable variability. Our objective was to retrospectively study patients from our institution aged <30 years with gastric carcinoma. The study was undertaken to describe the experience of gastric cancer in this population, and to demonstrate its specific clinical and pathological characteristics. We reviewed the cases of histologically confirmed gastric cancer between 1985 and 2006 at the Instituto Nacional de Cancerología of Mexico (INCan); emphasis in our review was placed on clinical presentation, diagnostic and therapeutic intervention, pathology, and the results. Thirty cases of gastric carcinoma were reviewed. The patients’ median age was 27 years (range, 18–30 years) and the male:female ratio was 1:1. Gastric cancer exhibits different behavior in patients aged, 30 years, but delay in diagnosis and the tumor’s behavior appear to be the most important factors in prognosis of the disease

    The aim of this review is to present a general overview about the importance of micro RNAs (miRNAs) in colorectal carcinoma. First, we focused on the mechanisms whereby the miRNAs regulate the expression of target genes, and how an altered regulation of them is associated with several types of cancer, including colorectal carcinoma. Later, examples of some miRNAs that have been associated with cancer development and how the expression patterns of specific miRNAs can be used as potential biomarkers for prognosis, diagnosis and therapeutic outcome in colorectal carcinoma are addressed. Finally, several polymorphisms presents in the miRNAs that have been associated to risk and prognosis in colorectal carcinoma are described.

    2017-07-01

    An interpretive analysis of 38 state dementia plans compares similarities and differences in diagnostic framing (problem identification/trends/issues), prognosis framing (addressing the problem), and motivational framing (calls for action) across plans. In framing diagnosis, only 6 plans used dementia alone in their titles. In framing prognosis and the subsequent call to action, state plans were consistent in their dire prognostications about the progressive and fatal consequences of the disease with a primary focus on the cost. Motivational language mirrored that of the Alzheimer's Disease (AD) Movement, from raising awareness to using inflammatory words to incite action. The language used set up the frame for clinical interventions that may not distinguish between types of dementia and could undercut the provision of person-centered care, shifts the victimization focus from persons with AD to caregivers and ultimately the state, and may subintentionally reflect cultural biases.

    Full Text Available Sepsis represents a severe pathology that requires both rapid and precise positive and differential diagnosis to identify patients who need immediate antimicrobial therapy. Monitoring septic patients′ outcome leads to prolonged hospitalisation and antibacterial therapy, often accompanied by substantial side effects, complications and a high mortality risk. Septic patients present with complex pathophysiological and immunological disorders and with a predominance of pro-inflammatory or anti-inflammatory mediators which are heterogeneous with respect to the infectious focus, the aetiology of sepsis or patients′ immune status or comorbidities. Previous studies performed have analysed inflammatory biomarkers, but a test or combinations of tests that can quickly and precisely establish a diagnosis or prognosis of septic patients has yet to be discovered. Recent research has focused on re-analysing older accessible parameters found in the complete blood count to determine the sensitivity, specificity, positive and negative predictive values for the diagnosis and prognosis of sepsis. The neutrophil/lymphocyte count ratio (NLCR, mean platelet volume (MPV and red blood cells distribution width (RDW are haemogram indicators which have been evaluated and which are of proven use in septic patients′ management.

    This study shows a first application of Raman microspectroscopy to the study of thyroid tissue samples classified as carcinomas, adenomas and nodules. Treatment of the Raman data using statistical methods show that it is possible to classify most of the samples in accord with the pathological examinations. Furthermore, Raman spectral image based on specific bands or frequencies defined as 'functional descriptors' allow to construct maps of micro- zones of such tissues. Such maps can be useful as complementary tools for tissue diagnosis and prognosis, since they carry molecular information important to such ends.

    Full Text Available The present study was conducted on 5 cows diagnosed with late-stage pericarditis based on a combination of clinical, radiographic, ultrasonographic, and postmortem examinations. On clinical examination, all the cows were found to be depressed, dyspnoeic, and moderately to severely tachycardic. The main radiographic findings were poor thoracic details and indistinguishable cardiophrenic silhouette. Ultrasonographically, the pericardial sac contained varying quantities of hypoechogenic exudate and echogenic fibrin shreds, which had caused physical compression of the cardiac chambers. The clinical and radiographic findings did not allow a definitive diagnosis of pericarditis, because all of the characteristic signs were not present in every case. Thoracic and abdominal ultrasonography played an important role in the early diagnosis and prognosis of the disease.

    Full Text Available Serum tumor markers (TM are widely used for diagnosis and monitoring of treatment of cancer. Carcinoembryonic Antigen (CEA is one of the most widely investigated tumor markers in gastrointestinal (GI cancers. Estimation of circulating tumor markers is a non- invasive quantitative method. Serum levels of CEA were studied for diagnosis and prognosis of gastrointestinal malignancies. 140 subjects were undertaken out of which 35 normal and remaining 105 were GI cancer patients. Serum levels of CEA were analyzed by Enzyme Linked Immunosorbent Assay (ELISA. Result of serum CEA levels of the GI cancer patients and normal subjects were analyzed statistically. It was observed that there was significant increase in (P <0.01 in CEA levels of oesophagus, stomach and colon cancer patients as compared to normal subjects. The levels of CEA decreased significantly after the surgery but the decrease in levels of CEA was not up to the levels as normal control subjects.

  9. Dreams as an aid in determining diagnosis, prognosis, and attitude towards treatment.

    Sabini, M

    1981-01-01

    The are certain types of dreams, in both psychosomatic and general medical patients, that address themselves directly - in undisguised form - to illness. From a collection of 60 such dreams, examples are presented which illustrate the objective value dreams can have in determining diagnosis, prognosis, and patient's attitude towards treatment. These dreams bring to light crucial factors that could affect treatment, such as the unconscious need for symptoms, the purposive function of symptoms, and unconscious resistances to treatment. Dreams may also reveal an unconscious knowledge of impending death in terminal patients. Although it is usually the patient who has dreams relevant to an existing illness, family members or the physician or therapist may also have them. This study makes a link with ancient Greek medical tradition in which dreams had a central role in both diagnosis and treatment. The possibility of revitalizing this tradition is noted, and the need for systematic research into dreams associated with illness is emphasized.

    Roychoudhury, I.; Hafiychuk, V.; Goebel, K.

    A water recycling system (WRS) deployed at NASA Ames Research Center's Sustainability Base (an energy efficient office building that integrates some novel technologies developed for space applications) will serve as a testbed for long duration testing of next generation spacecraft water recycling systems for future human spaceflight missions. This system cleans graywater (waste water collected from sinks and showers) and recycles it into clean water. Like all engineered systems, the WRS is prone to standard degradation due to regular use, as well as other faults. Diagnostic and prognostic applications will be deployed on the WRS to ensure its safe, efficient, and correct operation. The diagnostic and prognostic results can be used to enable condition-based maintenance to avoid unplanned outages, and perhaps extend the useful life of the WRS. Diagnosis involves detecting when a fault occurs, isolating the root cause of the fault, and identifying the extent of damage. Prognosis involves predicting when the system will reach its end of life irrespective of whether an abnormal condition is present or not. In this paper, first, we develop a physics model of both nominal and faulty system behavior of the WRS. Then, we apply an integrated model-based diagnosis and prognosis framework to the simulation model of the WRS for several different fault scenarios to detect, isolate, and identify faults, and predict the end of life in each fault scenario, and present the experimental results.

    RNA-based diagnosis and prognosis of squamous cell carcinoma has been slow to come to the clinic. Improvements in RNA measurement, statistical evaluation, and sample preservation, along with increased sample numbers, have not made these methods reproducible enough to be used clinically. We propose that, in the case of squamous cell carcinoma of the oral cavity, a chief source of variability is sample dissection, which leads to variable amounts of stroma mixed in with tumor epithelium. This heterogeneity of the samples, which requires great care to avoid, makes it difficult to see changes in RNA levels specific to tumor cells. An evaluation of the data suggests that, paradoxically, brush biopsy samples of oral lesions may provide a more reproducible method than surgical acquisition of samples for miRNA measurement. The evidence also indicates that body fluid samples can show similar changes in miRNAs with oral squamous cell carcinoma (OSCC) as those seen in tumor brush biopsy samples - suggesting much of the miRNA in these samples is coming from the same source: tumor epithelium. We conclude that brush biopsy or body fluid samples may be superior to surgical samples in allowing miRNA-based diagnosis and prognosis of OSCC in that they feature a rapid method to obtain homogeneous tumor cells and/or RNA.

    2014-12-01

    Although thermal performance tests implemented using industrial codes and standards can provide officially trustworthy results, they are essentially resource-consuming and maybe even a hind-sighted technique rather than a foresighted one, considering their periodicity. Therefore, if more accurate performance monitoring can be achieved using advanced data analysis techniques, we can expect more optimized operations and maintenance. This paper proposes a framework and describes associated methodologies for in-situ thermal performance analysis, which differs from conventional performance monitoring. The methodologies are effective for monitoring, diagnosis, and prognosis in pursuit of CBM. Our enabling techniques cover the intelligent removal of random and systematic errors, deviation detection between a best condition and a currently measured condition, degradation diagnosis using a structured knowledge base, and prognosis for decision-making about maintenance tasks. We also discuss how our new methods can be incorporated with existing performance tests. We provide guidance and directions for developers and end-users interested in in-situ thermal performance management, particularly in NPPs with large steam turbines.

    2001-07-01

    Many systems are comprised of components equipped with self-testing capability; however, if the system is complex involving feedback and the self-testing itself may occasionally be faulty, tracing faults to a single or multiple causes is difficult. Moreover, many sensors are incapable of reliable decision-making on their own. In such cases, a signal processing front-end that can match inference needs will be very helpful. The work is concerned with providing an object-oriented simulation environment for signal processing and neural network-based fault diagnosis and prognosis. In the toolbox, we implemented a wide range of spectral and statistical manipulation methods such as filters, harmonic analyzers, transient detectors, and multi-resolution decomposition to extract features for failure events from data collected by data sensors. Then we evaluated multiple learning paradigms for general classification, diagnosis and prognosis. The network models evaluated include Restricted Coulomb Energy (RCE) Neural Network, Learning Vector Quantization (LVQ), Decision Trees (C4.5), Fuzzy Adaptive Resonance Theory (FuzzyArtmap), Linear Discriminant Rule (LDR), Quadratic Discriminant Rule (QDR), Radial Basis Functions (RBF), Multiple Layer Perceptrons (MLP) and Single Layer Perceptrons (SLP). Validation techniques, such as N-fold cross-validation and bootstrap techniques, are employed for evaluating the robustness of network models. The trained networks are evaluated for their performance using test data on the basis of percent error rates obtained via cross-validation, time efficiency, generalization ability to unseen faults. Finally, the usage of neural networks for the prediction of residual life of turbine blades with thermal barrier coatings is described and the results are shown. The neural network toolbox has also been applied to fault diagnosis in mixed-signal circuits.

    To assess the prevalence and describe the clinical, laboratory and radiological findings, treatment and outcome of children with cancer initially referred to a tertiary outpatient pediatric rheumatology clinic. Retrospective analysis of medical records from patients identified in a list of 250 new patients attending the tertiary Pediatric Rheumatology Clinic, Ribeirão Preto Medical School hospital, University of São Paulo, from July 2013 to July 2015, whose final diagnosis was cancer. Of 250 patients seen during the study period, 5 (2%) had a cancer diagnosis. Among them, 80% had constitutional symptoms, especially weight loss and asthenia, and 60% had arthritis. Initially, all patients had at least one alteration in their blood count, lactate dehydrogenase was increased in 80% and a bone marrow smear was conclusive in 60% of patients. Bone and intestine biopsies were necessary for the diagnosis in 2 patients. JIA was the most common initial diagnosis. The definitive diagnosis was acute lymphoblastic leukemia (2 patients), M3 acute myeloid leukemia, lymphoma, and neuroblastoma (one case each). Of 5 patients studied, 3 (60%) are in remission and 2 (40%) died, one of them with prior use of steroids. The constitutional and musculoskeletal symptoms common to rheumatic and neoplastic diseases can delay the diagnosis and consequently worsen the prognosis of neoplasms. Initial blood count and bone marrow smear may be normal in the initial framework of neoplasms. Thus, the clinical follow-up of these cases becomes imperative and the treatment, mainly with corticosteroids, should be delayed until diagnostic definition. Copyright © 2017 Elsevier Editora Ltda.

    Selective immunoglobulin A deficiency (SIgAD) is the most common primary antibody deficiency. Although more patients with SIgAD are asymptomatic, selected patients suffer from different clinical complications such as pulmonary infections, allergies, autoimmune diseases, gastrointestinal disorders and malignancy. Pathogenesis of SIgAD is still unknown; however, a defective terminal differentiation of B cells and defect in switching to IgA-producing plasma cells are presumed to be responsible. Furthermore, some cytogenic defects and monogenic mutations are associated with SIgAD. There is no specific treatment for patients with symptomatic IgA deficiency, although prophylactic antibiotic therapy along with circumstantial immunoglobulin replacement with justification and supportive care (using a product that contains minimal IgA) could be helpful for patients with a severe phenotype. The epidemiology, pathogenesis, clinical phenotype, diagnosis, prognosis, management and treatment in patients with SIgAD have been reviewed. © 2016 The Foundation for the Scandinavian Journal of Immunology.

    In this paper, the synchronous signal average of gear mesh vibration signals is modelled with the multiple modulated sinusoidal representations. The signal model parameters are optimised against the measured signal averages by using the batch learning of the least squares technique. With the optimal signal model, all components of a gear mesh vibration signal, including the amplitude modulations, the phase modulations and the impulse vibration component induced by gear tooth cracking, are identified and analysed with insight of the gear tooth crack development and propagation. In particular, the energy distribution of the impulse vibration signal, extracted from the optimal signal model, provides sufficient information for monitoring and diagnosing the evolution of the tooth cracking process, leading to the prognosis of gear tooth cracking. The new methodologies for gear mesh signal modelling and the diagnosis of the gear tooth fault development and propagation are validated with a set of rig test data, which has shown excellent performance.

    Reading and spelling disorder (dyslexia) is one of the more common specific developmental disorders, with a prevalence of approximately 5%. It is characterized by severe impairment of learning to read and spell. We discuss major aspects of the diagnosis, treatment, and prevention of dyslexia on the basis of a selective literature review and the guidelines of the German Society of Child and Adolescent Psychiatry, Psychosomatics and Psychotherapy. 40% to 60% of dyslexic children have psychological manifestations, including anxiety, depression, and attention deficit. The diagnostic assessment of dyslexia consists of a battery of standardized reading and spelling tests and an evaluation of the child's psychological state, including additional information obtained from parents and teachers. The treatment of dyslexia is based on two main strategies: specific assistance with the impaired learning areas (reading and spelling) and psychotherapy for any coexisting psychological disturbance that may be present. Evaluated preventive strategies are available for use in kindergarten and at home. The diagnosis of dyslexia should be established with the aid of the multiaxial classification system. The benefit of specific treatment strategies for dyslexia has not yet been demonstrated empirically. Nonetheless, evaluated prevention programs are available in kindergarten that have been found to promote children's ability to acquire reading and spelling skills in school.

    To evaluate the value of combined detection of serum CEA, CA19-9, CA24-2, AFP, CA72-4, SCC, TPA and TPS for the clinical diagnosis of upper gastrointestinal tract (GIT) cancer and to analyze the efficacy of these tumor markers (TMs) in evaluating curative effects and prognosis. A total of 573 patients with upper GIT cancer between January 2004 and December 2007 were enrolled in this study. Serum levels of CEA, CA19-9, CA24-2, AFP, CA72-4, SCC, TPA and TPS were examined preoperatively and every 3 months postoperatively by ELISA. The sensitivity of CEA, CA19-9, CA24-2, AFP, CA72-4, SCC, TPA and TPS were 26.8%, 36.2%, 42.9%, 2.84%, 25.4%, 34.6%, 34.2% and 30.9%, respectively. The combined detection of CEA+CA199+CA242+CA724 had higher sensitivity and specificity in gastric cancer (GC) and cardiac cancer, while CEA+CA199+CA242+SCC was the best combination of diagnosis for esophageal cancer (EC). Elevation of preoperative CEA, CA19-9 and CA24-2, SCC and CA72-4 was significantly associated with pathological types (pCEA, CA19-9, CA24-2, CA72-4 and SCC decreased obviously 3 months after operations. When metastasis and recurrence occurred, the levels of TMs significantly increased. On multivariate analysis, high preoperative CA72-4, CA24-2 and SCC served as prognostic factors for cardiac carcinoma, GC and EC, respectively. combined detection of CEA+CA199+CA242+SCC proved to be the most economic and practical strategy in diagnosis of EC; CEA+CA199+CA242+CA724 proved to be a better evaluation indicator for cardiac cancer and GC. CEA and CA19-9, CA24-2, CA72-4 and SCC, examined postoperatively during follow-up, were useful to find early tumor recurrence and metastasis, and evaluate prognosis. AFP, TPA and TPS have no significant value in diagnosis of patients with upper GIT cancer.

  6. Novel Biomarker Proteins in Chronic Lymphocytic Leukemia: Impact on Diagnosis, Prognosis and Treatment.

    Full Text Available In many cancers, cells undergo re-programming of metabolism, cell survival and anti-apoptotic defense strategies, with the proteins mediating this reprogramming representing potential biomarkers. Here, we searched for novel biomarker proteins in chronic lymphocytic leukemia (CLL that can impact diagnosis, treatment and prognosis by comparing the protein expression profiles of peripheral blood mononuclear cells from CLL patients and healthy donors using specific antibodies, mass spectrometry and binary logistic regression analyses and other bioinformatics tools. Mass spectrometry (LC-HR-MS/MS analysis identified 1,360 proteins whose expression levels were modified in CLL-derived lymphocytes. Some of these proteins were previously connected to different cancer types, including CLL, while four other highly expressed proteins were not previously reported to be associated with cancer, and here, for the first time, DDX46 and AK3 are linked to CLL. Down-regulation expression of two of these proteins resulted in cell growth inhibition. High DDX46 expression levels were associated with shorter survival of CLL patients and thus can serve as a prognosis marker. The proteins with modified expression include proteins involved in RNA splicing and translation and particularly mitochondrial proteins involved in apoptosis and metabolism. Thus, we focused on several metabolism- and apoptosis-modulating proteins, particularly on the voltage-dependent anion channel 1 (VDAC1, regulating both metabolism and apoptosis. Expression levels of Bcl-2, VDAC1, MAVS, AIF and SMAC/Diablo were markedly increased in CLL-derived lymphocytes. VDAC1 levels were highly correlated with the amount of CLL-cancerous CD19+/CD5+ cells and with the levels of all other apoptosis-modulating proteins tested. Binary logistic regression analysis demonstrated the ability to predict probability of disease with over 90% accuracy. Finally, based on the changes in the levels of several proteins in

    This paper aims to address the ethical issues regarding prenatal diagnosis and preimplantation genetic diagnosis (PGD) of mitochondrial disorders. Owing to the absence of effective treatment, the prevention of the transmission of mitochondrial disorders is considered to be of key importance. The characteristics of mtDNA, such as heteroplasmy and the genetic bottleneck, make it difficult to estimate recurrence risks correctly and to provide an accurate prognosis for many mtDNA mutations. A limited number of mtDNA mutations allow reliable predictions, though results in the 'grey zone' are problematic. Both prenatal diagnosis and PGD for mtDNA disorders are complicated by the interpretation of the test results. As a consequence, these applications confront both clinical practice and society at large with several ethical questions and issues for further debate, among which the acceptability of suboptimal genetic testing, the value and research use of embryos, the evaluation of late abortion, the ethics of PGD for disorders with an incomplete penetrance and variable expression, the possible transfer of embryos with residual health risks, the acceptability of risks and drawbacks of genetic reproductive technology in general, and the scope and limits of reproductive autonomy and professional responsibility.

    Full Text Available Neurodegenerative diseases present a current challenge for accurate diagnosis and for providing precise prognostic information. Developing imaging biomarkers for multiple sclerosis (MS, Parkinson disease (PD, and Alzheimer’s disease (AD will improve the clinical management of these patients and may be useful for monitoring treatment effectiveness. Recent research using optical coherence tomography (OCT has demonstrated that parameters provided by this technology may be used as potential biomarkers for MS, PD, and AD. Retinal thinning has been observed in these patients and new segmentation software for the analysis of the different retinal layers may provide accurate information on disease progression and prognosis. In this review we analyze the application of retinal evaluation using OCT technology to provide better understanding of the possible role of the retinal layers thickness as biomarker for the detection of these neurodegenerative pathologies. Current OCT analysis of the retinal nerve fiber layer and, specially, the ganglion cell layer thickness may be considered as a good biomarker for disease diagnosis, severity, and progression.

    Numerous studies have examined the association between body weight, nutritional factors, physical activity and the risk for primary breast cancer. Relatively few studies, however, have examined the associations between these issues and the recurrence of the disease and cure of the primary tumor. Today, three areas of focus are actively being researched for breast cancer survivors: body weight, diet composition and physical activity with specific emphasis on the risk for recurrence, survival and quality of life. Increased body weight or BMI (Body Mass Index) at diagnosis was found to be a significant risk factor for recurrent disease, decreased survival, or both. Overall obesity has been shown to adversely affect prognosis. Appropriate weight control may be particularly beneficial for breast cancer survivors. Breast cancer survivors should be encouraged to achieve and maintain a healthy weight. Limiting fat intake can reduce the risk of breast cancer recurrence. Increasing consumption of vegetables and fruits seems to have possible beneficial effects during and after treatments. To date physical activity after breast cancer diagnosis has been found to reduce the risk of death. The greatest benefit occurred in women who performed the equivalent of walking 3-5 hours per week at an average pace. Safe weight loss via increased physical activity and healthful food choices should be encouraged for normal, overweight or obese breast cancer survivors in order to improve survival and life quality.

    In low- and middle-income countries, the association between delay to treatment and prognosis for Kaposi's sarcoma (KS) patients is yet to be studied. This is a prospective study of HIV-infected adults with histologically-confirmed KS treated at the Uganda Cancer Institute (UCI). Standardized interviews were conducted in English or Luganda. Medical records were abstracted for KS stage at admission to UCI. Multivariable logistic regression assessed relationships between diagnostic delay and stage at diagnosis. Of 161 patients (90% response rate), 69% were men, and the mean age was 34.0 years (SD 7.7). 26% had been seen in an HIV clinic within 3 months, 72% were on antiretroviral therapy, and 26% had visited a traditional healer prior to diagnosis. 45% delayed seeking care at UCI for ≥3 months from symptom onset. Among those who delayed, 36% waited 6 months, and 25% waited 12 months. Common reasons for delay were lack of pain (48%), no money (32%), and distance to UCI (8%). In adjusted analysis patients who experienced diagnostic delay were more likely than those who did not delay to have poor-risk KS stage (OR 3.41, p = 0.002, 95% CI: 1.46-7.45). In adjusted analyses visiting a traditional healer was the only variable associated with greater likelihood of delay (OR 2.69, p = 0.020, 95% CI: 1.17-6.17). Diagnostic delay was associated with poor-risk stage at diagnosis, and visiting a traditional healer was associated with higher odds of delay. The relationship between traditional and Western medicine presents a critical intervention point to improve KS-related outcomes in Uganda.

    Prediction models are developed to aid health care providers in estimating the probability or risk that a specific disease or condition is present (diagnostic models) or that a specific event will occur in the future (prognostic models), to inform their decision making. However, the overwhelming evidence shows that the quality of reporting of prediction model studies is poor. Only with full and clear reporting of information on all aspects of a prediction model can risk of bias and potential usefulness of prediction models be adequately assessed. The Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis (TRIPOD) Initiative developed a set of recommendations for the reporting of studies developing, validating, or updating a prediction model, whether for diagnostic or prognostic purposes. This article describes how the TRIPOD Statement was developed. An extensive list of items based on a review of the literature was created, which was reduced after a Web-based survey and revised during a 3-day meeting in June 2011 with methodologists, health care professionals, and journal editors. The list was refined during several meetings of the steering group and in e-mail discussions with the wider group of TRIPOD contributors. The resulting TRIPOD Statement is a checklist of 22 items, deemed essential for transparent reporting of a prediction model study. The TRIPOD Statement aims to improve the transparency of the reporting of a prediction model study regardless of the study methods used. The TRIPOD Statement is best used in conjunction with the TRIPOD explanation and elaboration document. To aid the editorial process and readers of prediction model studies, it is recommended that authors include a completed checklist in their submission (also available at www.tripod-statement.org).

    Milk fistula is an uncommon condition which occurs when there is an abnormal connection that forms between the skin surface and the duct in the breast of a lactating woman, resulting in spontaneous and often constant drainage of milk from this path of least resistance. A milk fistula is usually a complication that results from a needle biopsy or surgical intervention in a lactating patient. Here, the authors present an unusual case of a spontaneous milk fistula which developed from an abscess in the breast of a lactating woman. The patient initially presented to the office with a large open wound on her breast, formed from skin breakdown, within which milk was pooling. She was treated with local wound care and cessation of breastfeeding, with appropriate healing of the wound and closure of the fistula with 6 weeks. Diagnosis, prevention, and treatment of milk fistula were reviewed. © 2015 Wiley Periodicals, Inc.

    Recent advances in functional neuroimaging have demonstrated novel potential for informing diagnosis and prognosis in the unresponsive wakeful syndrome and minimally conscious states. However, these technologies come with considerable expense and difficulty, limiting the possibility of wider clinical application in patients. Here, we show that high density electroencephalography, collected from 104 patients measured at rest, can provide valuable information about brain connectivity that correlates with behaviour and functional neuroimaging. Using graph theory, we visualize and quantify spectral connectivity estimated from electroencephalography as a dense brain network. Our findings demonstrate that key quantitative metrics of these networks correlate with the continuum of behavioural recovery in patients, ranging from those diagnosed as unresponsive, through those who have emerged from minimally conscious, to the fully conscious locked-in syndrome. In particular, a network metric indexing the presence of densely interconnected central hubs of connectivity discriminated behavioural consciousness with accuracy comparable to that achieved by expert assessment with positron emission tomography. We also show that this metric correlates strongly with brain metabolism. Further, with classification analysis, we predict the behavioural diagnosis, brain metabolism and 1-year clinical outcome of individual patients. Finally, we demonstrate that assessments of brain networks show robust connectivity in patients diagnosed as unresponsive by clinical consensus, but later rediagnosed as minimally conscious with the Coma Recovery Scale-Revised. Classification analysis of their brain network identified each of these misdiagnosed patients as minimally conscious, corroborating their behavioural diagnoses. If deployed at the bedside in the clinical context, such network measurements could complement systematic behavioural assessment and help reduce the high misdiagnosis rate reported

    The lack of knowledge regarding polycystic hydatid disease results in delayed or even incorrect diagnosis. The lack of systematic information regarding treatment also makes it difficult to assess the results and prognosis in patients with peritoneal and hepatic lesions caused by Echinococcus vogeli. Here we describe the clinical features of patients, propose a radiological classification protocol and describe a therapeutic option for the treatment of hydatid disease that previously had only been used for cases of cystic echinococcosis (Echinococcus granulosus). A prospective cohort study was initiated in 1999 and by 2009 the study included 60 patients. These patients were classified according to the PNM classification (parasite lesion, neighbouring organ invasion and metastases) and placed in one of three therapeutic modalities: (i) chemotherapy with albendazole at a dose of 10 mg/kg/day, (ii) surgical removal of cysts or (iii) percutaneous puncture of the cysts via puncture, aspiration, injection and re-aspiration (PAIR). The results were stratified according to therapeutic outcome: "cure", "clinical improvement", "no improvement", "death" or "no information". The PNM classification was useful in indicating the appropriate therapy in cases of polycystic hydatid disease. In conclusion, surgical therapy produced the best clinical results of all the therapies studied based on "cure" and "clinical improvement" outcomes. The use of PAIR for treatment requires additional study. PMID:23903966

    Full Text Available Introduction. This study aimed to investigate the currency of computerized tomography pulmonary angiography-based parameters as pulmonary artery obstruction index (PAOI, as well as right ventricular diameters for pulmonary embolism (PE risk evaluation and prediction of mortality and intensive care unit (ICU requirement. Materials and Methods. The study retrospectively enrolled 203 patients hospitalized with acute PE. PAOI was calculated according to Qanadli score. Results. Forty-three patients (23.9% were hospitalized in the ICU. Nineteen patients (10.6% died during the 30-day follow-up period. The optimal cutoff value of PAOI for PE 30th day mortality and ICU requirement were found as 36.5% in ROC curve analysis. The pulmonary artery systolic pressure had a significant positive correlation with right/left ventricular diameter ratio (r=0.531, P<0.001, PAOI (r=0.296, P<0.001, and pulmonary artery diameter (r=0.659, P<0.001. The patients with PAOI values higher than 36.5% have a 5.7-times increased risk of death. Conclusion. PAOI is a fast and promising parameter for risk assessment in patients with acute PE. With greater education of clinicians in this radiological scoring, a rapid assessment for diagnosis, clinical risk evaluation, and prognosis may be possible in emergency services without the need for echocardiography.

    Autism is defined as a neurologic developmental disorder affecting brain and behavior, becoming usually apparent before 3 years of age, with stable evolution and no remission. No neurologic morphologic abnormality was associated with the disease. Several types of disease being described, autism is part of a larger spectrum known as autism spectrum disorders (ASD), or pervasive developmental disorders (PDD). The disease was first described long before it was defined and it has received its modern name. Main cause in the development of autism is considered to be genetic, up to 90 %. However, environmental factors could be incriminated, sometimes. The five types included in ASD are: Asperger syndrome, pervasive developmental disorder-not otherwise specified (PDD-NOS), typical autism, Rett syndrome and childhood disintegrative disorder (CDD). The classical triad of symptoms includes: social interaction impairments, communication impairments and repetitive, stereotype behavior. Diagnosis is based on interview of the parents and specialized observation of the suspected children. Main tools used in therapy are the family and the educational system. Well established, specialized programs of therapy were developed in time. Prognosis of autism is severe, since no cure is possible; nevertheless spontaneous recoveries do occur, in some cases.

    Full Text Available PURPOSE: To compare a commercially available Latex agglutination test and an in house co-agglutination test for the detection of cryptococcal antigen in cases of chronic meningitis. METHODS: One hundred and fifty cerebrospinal fluid (CSF samples from 150 cases of chronic meningitis were tested for the presence of Cryptococcus neoformans by modified India ink, culture and antigen detection by latex agglutination test (LAT and co-agglutination (Co-A test. RESULTS: Thirty-nine cases were positive by one or more tests employed. Antigen detection in CSF by LAT and Co-A was found to be most sensitive (94.9% while culture was the least (25.6%. Of the two antigen detection methods, Co-A was found to be more sensitive than the LAT, the difference being statistically significant. Initial CSF antigen titres did not have any prognostic significance. CONCLUSIONS: Co-A for antigen detection is an inexpensive and useful adjunct to direct microscopy and culture for the diagnosis of cryptococcal meningitis, though its usefulness in prognosis needs to be evaluated further.

    The aim of this longitudinal study is to describe the different intralabyrinthine lesions yielding high signal intensity on T1-weighted (T1W) images after intravenous gadolinium and then to analyze the follow-up of these patients. Thirty-seven patients were included and followed clinically and radiologically. A precise analysis of MR labyrinthine signals allowed exact depiction of the different lesions. Special interest is focused on the intralabyrinthine fluid signal on 3D high-resolution T2W images. The enhanced T1W labyrinthine hyperintensities correspond to two different categories: intralabyrinthine enhancement (15 intralabyrinthine schwannomas, 13 labyrinthitis, 1 inflammatory granuloma) and spontaneous T1W hyperintensities (8 intralabyrinthine hemorrhages). Hemorrhagic lesions show a substantial decrease of the intralabyrinthine fluid signal on the 3D HRT2 that evolves to ossification. In labyrinthitis, the importance of the initial labyrinthine fluid signal decrease on the 3D HRT2 is well correlated with the hearing prognosis. A meticulous analysis of inner ear lesions allows various intralabyrinthine lesions, in particular schwannomas, to be differentiated from labyrinthitis. T1W imaging without gadolinium is essential for the correct diagnosis of rapidly evolving hearing loss. In labyrinthitis and intralabyrinthine hemorrhage, 3D HRT2 brings an interesting prognostic factor for the chance of hearing recovery. (orig.)

    The authors underline the importance of dreams in the initial phases of psychoanalysis as an instrument of diagnosis and prognosis. In these first phases of explorative analysis or of consultation the dreams will show the structures and the deep mental dynamics of the patient, they will also show the expectations that the patient has with regard to the therapeutic prospects, and also the effectiveness of the encounter between patient and therapist. The authors underline the significance of the moment in which the dreams are told to the analyst: it is possible, therefore, to speak about anamnestic dreams, about dreams that are a consequence of the decision to start an analysis, about dreams that referred to the first contact between the patient and the analyst, about dreams that concern the consultation phase broadly. The authors, moreover, describe several examples of patients' dreams in the first phases of explorative analysis and they supply them with an interpretation and with a diagnostic and prognostic use, and they also propose indications on how and in what way and if it is the case to continue the therapy.

These patients were classified according to the PNM classification (parasite lesion, neighbouring organ invasion and metastases and placed in one of three therapeutic modalities: (i chemotherapy with albendazole at a dose of 10 mg/kg/day, (ii surgical removal of cysts or (iii percutaneous puncture of the cysts via puncture, aspiration, injection and re-aspiration (PAIR. The results were stratified according to therapeutic outcome: "cure", "clinical improvement", "no improvement", "death" or "no information". The PNM classification was useful in indicating the appropriate therapy in cases of polycystic hydatid disease. In conclusion, surgical therapy produced the best clinical results of all the therapies studied based on "cure" and "clinical improvement" outcomes. The use of PAIR for treatment requires additional study.

    Considering epidemiological, genetic and immunological data, we can conclude that the inflammatory bowel diseases are heterogeneous disorders of multifactorial etiology in which hereditability and environment interact to produce the disease. It is probable that patients have a genetic predisposition for the development of the disease coupled with disturbances in immunoregulation. Several genes have been so far related to the diagnosis of Crohn’s disease. Those genes are related to innate pattern recognition receptors, to epithelial barrier homeostasis and maintenance of epithelial barrier integrity, to autophagy and to lymphocyte differentiation. So far, the most strong and replicated associations with Crohn’s disease have been done with NOD2, IL23R and ATG16L1 genes. Many genes have so far been implicated in prognosis of Crohn’s disease and many attempts have been made to classify genetic profiles in Crohn’s disease. CARD15 seems not only a susceptibility gene, but also a disease-modifier gene for Crohn’s disease. Enriching our understanding on Crohn’s disease genetics is important but when combining genetic data with functional data the outcome could be of major importance to clinicians. PMID:22253516

    Glycoprotein 2 (GP2), the pancreatic major zymogen granule membrane glycoprotein, was reported to be elevated in acute pancreatitis in animal models. Enzyme-linked immunosorbent assays (ELISAs) were developed to evaluate human glycoprotein 2 isoform alpha (GP2a) and total GP2 (GP2t) as specific markers for acute pancreatitis in sera of 153 patients with acute pancreatitis, 26 with chronic pancreatitis, 125 with pancreatic neoplasms, 324 with non-pancreatic neoplasms, 109 patients with liver/biliary disease, 67 with gastrointestinal disease, and 101 healthy subjects. GP2a and GP2t levels were correlated with procalcitonin and C-reactive protein in 152 and 146 follow-up samples of acute pancreatitis patients, respectively. The GP2a ELISA revealed a significantly higher assay accuracy in contrast to the GP2t assay (sensitivity ≤3 disease days: 91.7%, specificity: 96.7%, positive likelihood ratio [LR+]: 24.6, LR-: 0.09). GP2a and GP2t levels as well as prevalences were significantly elevated in early acute pancreatitis (≤3 disease days) compared to all control cohorts (ppancreatitis at admission compared with mild cases (ppancreatitis with lethal outcome was 7.8 on admission (p=0.0222). GP2a and GP2t levels were significantly correlated with procalcitonin [Spearman's rank coefficient of correlation (ρ)=0.21, 0.26; p=0.0110, 0.0012; respectively] and C-reactive protein (ρ=0.37, 0.40; ppancreatitis and analysis of GP2a can aid in the differential diagnosis of acute upper abdominal pain and prognosis of severe acute pancreatitis.

    This review summarizes present evidence for the role of YKL-40 in the diagnosis, prognosis and cause of cardiovascular and alcoholic liver disease. The question of whether YKL-40 is merely a marker or a causal factor in the development of cardiovascular and liver disease is addressed, with emphasis...... also hepatic stellate cells. Observational studies show that plasma YKL-40 levels are elevated in patients with cardiovascular and liver disease and are associated with disease severity and prognosis. Furthermore, elevated plasma YKL-40 levels in apparently healthy individuals are associated with a 2...... of cardiovascular and alcoholic liver disease, thus suggesting that plasma YKL-40 does not play a causal role in the development of these diseases. Despite this, plasma YKL-40 levels may play a role in disease progression after diagnosis, and inhibition of YKL-40 activity might be a novel therapy in some...

    While the plethora of information from multiple imaging and non-imaging data streams presents an opportunity for discovery of fused multimodal, multiscale biomarkers, they also introduce multiple independent sources of noise that hinder their collective utility. The goal of this work is to create fused predictors of disease diagnosis and prognosis by combining multiple data streams, which we hypothesize will provide improved performance as compared to predictors from individual data streams. To achieve this goal, we introduce supervised multiview canonical correlation analysis (sMVCCA), a novel data fusion method that attempts to find a common representation for multiscale, multimodal data where class separation is maximized while noise is minimized. In doing so, sMVCCA assumes that the different sources of information are complementary and thereby act synergistically when combined. Although this method can be applied to any number of modalities and to any disease domain, we demonstrate its utility using three datasets. We fuse (i) 1.5 Tesla (T) magnetic resonance imaging (MRI) features with cerbrospinal fluid (CSF) proteomic measurements for early diagnosis of Alzheimer's disease (n = 30), (ii) 3T Dynamic Contrast Enhanced (DCE) MRI and T2w MRI for in vivo prediction of prostate cancer grade on a per slice basis (n = 33) and (iii) quantitative histomorphometric features of glands and proteomic measurements from mass spectrometry for prediction of 5 year biochemical recurrence postradical prostatectomy (n = 40). Random Forest classifier applied to the sMVCCA fused subspace, as compared to that of MVCCA, PCA and LDA, yielded the highest classification AUC of 0.82 +/- 0.05, 0.76 +/- 0.01, 0.70 +/- 0.07, respectively for the aforementioned datasets. In addition, sMVCCA fused subspace provided 13.6%, 7.6% and 15.3% increase in AUC as compared with that of the best performing individual view in each of the three datasets, respectively. For the biochemical recurrence

    Alzheimer's disease (AD) is a major neurodegenerative disease and the most common cause of dementia. Currently, no treatment exists to slow down or stop the progression of AD. There is converging belief that disease-modifying treatments should focus on early stages of the disease, that is, the mild cognitive impairment (MCI) and preclinical stages. Making a diagnosis of AD and offering a prognosis (likelihood of converting to AD) at these early stages are challenging tasks but possible with the help of multimodality imaging, such as magnetic resonance imaging (MRI), fluorodeoxyglucose (FDG)-positron emission topography (PET), amyloid-PET, and recently introduced tau-PET, which provides different but complementary information. This article is a focused review of existing research in the recent decade that used statistical machine learning and artificial intelligence methods to perform quantitative analysis of multimodality image data for diagnosis and prognosis of AD at the MCI or preclinical stages. We review the existing work in 3 subareas: diagnosis, prognosis, and methods for handling modality-wise missing data-a commonly encountered problem when using multimodality imaging for prediction or classification. Factors contributing to missing data include lack of imaging equipment, cost, difficulty of obtaining patient consent, and patient drop-off (in longitudinal studies). Finally, we summarize our major findings and provide some recommendations for potential future research directions. Copyright © 2018 Elsevier Inc. All rights reserved.

    2017-10-01

    Full Text Available During the past century, our understanding of cancer diagnosis and treatment has been based on a monogenic approach, and as a consequence our knowledge of the clinical genetic underpinnings of cancer is incomplete. Since the completion of the human genome in 2003, it has steered us into therapeutic target discovery, enabling us to mine the genome using cutting edge proteogenomics tools. A number of novel and promising cancer targets have emerged from the genome project for diagnostics, therapeutics, and prognostic markers, which are being used to monitor response to cancer treatment. The heterogeneous nature of cancer has hindered progress in understanding the underlying mechanisms that lead to abnormal cellular growth. Since, the start of The Cancer Genome Atlas (TCGA, and the International Genome consortium projects, there has been tremendous progress in genome sequencing and immense numbers of cancer genomes have been completed, and this approach has transformed our understanding of the diagnosis and treatment of different types of cancers. By employing Genomics and proteomics technologies, an immense amount of genomic data is being generated on clinical tumors, which has transformed the cancer landscape and has the potential to transform cancer diagnosis and prognosis. A complete molecular view of the cancer landscape is necessary for understanding the underlying mechanisms of cancer initiation to improve diagnosis and prognosis, which ultimately will lead to personalized treatment. Interestingly, cancer proteome analysis has also allowed us to identify biomarkers to monitor drug and radiation resistance in patients undergoing cancer treatment. Further, TCGA-funded studies have allowed for the genomic and transcriptomic characterization of targeted cancers, this analysis aiding the development of targeted therapies for highly lethal malignancy. High-throughput technologies, such as complete proteome, epigenome, protein–protein interaction

    Musculoskeletal conditions are highly prevalent in our ageing society and are therefore incurring substantial increases in population levels of years lived with disability (YLD). An evidence-based approach to the prognosis, prevention, and treatment of those disorders can allow an overall improvement in the quality of life of patients, while also softening the burden on national health care systems. In this Masterclass article, we provide an overview of the most relevant twin study designs, their advantages, limitations and major contributions to the investigation of traits related to the domain of musculoskeletal physical therapy. Twin studies can be an important scientific tool to address issues related to musculoskeletal conditions. They allow researchers to understand how genes and environment combine to influence human health and disease. Twin registries and international collaboration through existing networks can provide resources for achieving large sample sizes and access to expertise in study design and analysis of twin data.

    2011-09-01

    Sudden sensorineural hearing loss (SSNHL) is commonly encountered in audiologic and otolaryngologic practice. SSNHL is most commonly defined as sensorineural hearing loss of 30 dB or greater over at least three contiguous audiometric frequencies occurring within a 72-hr period. Although the differential for SSNHL is vast, for the majority of patients an etiologic factor is not identified. Treatment for SSNHL of known etiology is directed toward that agent, with poor hearing outcomes characteristic for discoverable etiologies that cause inner ear hair cell loss. Steroid therapy is the current mainstay of treatment of idiopathic SSNHL in the United States. The prognosis for hearing recovery for idiopathic SSNHL is dependent on a number of factors including the severity of hearing loss, age, presence of vertigo, and shape of the audiogram.

    Gastric cancer continues to be an important healthcare problem from a global perspective. Most of the cases in the Western world are diagnosed at late stages when the treatment is largely ineffective. Helicobacter pylori (H. pylori) infection is a well-established carcinogen for gastric cancer. While lifestyle factors are important, the efficacy of interventions in their modification, as in the use of antioxidant supplements, is unconvincing. No organized screening programs can be found outside Asia (Japan and South Korea). Although several screening approaches have been proposed, including indirect atrophy detection by measuring pepsinogen in the circulation, none of them have so far been implemented, and more study data is required to justify any implementation. Mass eradication of H. pylori in high-risk areas tends to be cost-effective, but its adverse effects and resistance remain a concern. Searches for new screening biomarkers, including microRNA and cancer-autoantibody panels, as well as detection of volatile organic compounds in the breath, are in progress. Endoscopy with a proper biopsy follow-up remains the standard for early detection of cancer and related premalignant lesions. At the same time, new advanced high-resolution endoscopic technologies are showing promising results with respect to diagnosing mucosal lesions visually and targeting each biopsy. New histological risk stratifications (classifications), including OLGA and OLGIM, have recently been developed. This review addresses the current means for gastric cancer primary and secondary prevention, the available and emerging methods for screening, and new developments in endoscopic detection of early lesions of the stomach.

  7. Human voltage-gated proton channel hv1: a new potential biomarker for diagnosis and prognosis of colorectal cancer.

    Directory of Open Access Journals (Sweden)

    Yifan Wang

    Full Text Available Solid tumors exist in a hypoxic microenvironment, and possess high-glycolytic metabolites. To avoid the acidosis, tumor cells must exhibit a dynamic cytosolic pH regulation mechanism(s. The voltage-gated proton channel Hv1 mediates NADPH oxidase function by compensating cellular loss of electrons with protons. Here, we showed for the first time, that Hv1 expression is increased in colorectal tumor tissues and cell lines, associated with poor prognosis. Immunohistochemistry showed that Hv1 is strongly expressed in adenocarcinomas but not or lowly expressed in normal colorectal or hyperplastic polyps. Hv1 expression in colorectal cancer is significantly associated with the tumor size, tumor classification, lymph node status, clinical stage and p53 status. High Hv1 expression is associated significantly with shorter overall and recurrence-free survival. Furthermore, real-time RT-PCR and immunocytochemistry showed that Hv1 is highly expressed in colorectal cancer cell lines, SW620, HT29, LS174T and Colo205, but not in SW480. Inhibitions of Hv1 expression and activity in the highly metastatic SW620 cells by small interfering RNA (siRNA and Zn(2+ respectively, markedly decrease the cell invasion and migration, restraint proton extrusion and the intracellular pH recovery. Our results suggest that Hv1 may be used as a potential biomarker for diagnosis and prognosis of colorectal carcinoma, and a potential target for anticancer drugs in colorectal cancer therapy.

    Objective: To study the X-ray manifestations of alimentary tract perforation in neonates and investigate the pathogenesis and the prognosis. Methods: In total 65 cases of alimentary tract perforation in neonates were retrospectively studied, including the X-ray manifestations and the pathology. Results: Pneumo-peritoneum was revealed in 59 cases out of 65, including sever pneumo-peritoneum in 19 cases, moderate in 20 cases and mild in 20 cases. Free air was revealed in the sub-diaphragmatic regions in 55 cases. The following manifestations indicated pneumo-peritoneum: football sign (25 cases), falciform ligament sign (36 cases) and pencil-drawing sign (27 cases). Other findings included the absence of the gastric bulb revealed in 11 cases, increased distance between the bowel loops in 28, widen separation of the intestinal wall and the adjacent air filled loop in 34, air-containing bowel wall in 11, and feces air mixture within peripheral loops in 8 case. The primary affection included: defects of gastric musculature (11 cases), congenital malformation of small intestine (11 cases), Hirschsprung disease (8 cases), atresia of the anus (2 cases), meconium peritonitis (5 cases), NEC (24 cases), and other causes (4 cases). Conclusion: In the diagnosis of alimentary tract's perforation in neonates, Roentgenography is still the most important examination and the first choice of imaging. It also helps evaluating the pathogenesis and the prognosis of those disorders

  9. Serum tumor markers in chronic kidney disease: as clinical tool in diagnosis, treatment and prognosis of cancers.

    2016-01-01

    Cancer is singled out as the biggest cause of death in the world, predicted to reach 13.1 million cancer-related deaths by the year 2030. Although there are no specific tumor markers used in cancer screening, some markers can be used to assist in making a diagnosis and determining a prognosis. They can be used to follow in cases where the diagnosis is cancer through monitoring of the disease recurrence and/or evaluating the response to therapy. These markers are not specific as the number increases in multiple cases of cancer. Some markers are positive in a single type of cancer; others are detectable in more than one type. An ideal tumor marker should be highly sensitive, specific, and reliable with high prognostic value. Other characteristics of an ideal tumor marker are organ specificity and correlation of it with tumor stages. However, none of the tumor markers reported to date has all these characteristics. Influence of different stages of chronic kidney function on serum tumor markers is variable. Furthermore, hemodialysis, peritoneal dialysis, and kidney transplantation affect on tumor markers differently. Sometimes, no study has been found in the literature review. Combined serum tumor markers may also be valuable. This literature review points the role of serum tumor markers in screening, diagnosis, and follow-up of cancer patients in chronic kidney disease patients and renal allograft recipients. In addition, impact of chronic kidney disease and kidney transplantation on different serum tumor markers is briefly explored.

    Tang, Liang; Kang, Kyung A.

    A fiber-optic biosensing system for the simultaneous quantification of four cardiac markers is currently under development, in our research group, for rapid coronary disease diagnosis and prognosis. As an initial effort, four individual BNP, cTnI, MG, and CRP sensors were developed. The sensors showed excellent performance in quantifying these cardiac markers in their clinically significant ranges within 15 minutes, at a S/N ratio of 25-50. The cross-reactivity of the four sensors was also found to be negligible. A mixture of four AF647-2o Mabs has shown only a slight interference to the four sensors, indicating that the mixture can be applied through a multi-sensing unit for simultaneous detection with an easier operation.

    2017-06-01

    Full Text Available We provide a critical outlook of the evolution of Industrial Process Monitoring (IPM since its introduction almost 100 years ago. Several evolution trends that have been structuring IPM developments over this extended period of time are briefly referred, with more focus on data-driven approaches. We also argue that, besides such trends, the research focus has also evolved. The initial period was centred on optimizing IPM detection performance. More recently, root cause analysis and diagnosis gained importance and a variety of approaches were proposed to expand IPM with this new and important monitoring dimension. We believe that, in the future, the emphasis will be to bring yet another dimension to IPM: prognosis. Some perspectives are put forward in this regard, including the strong interplay of the Process and Maintenance departments, hitherto managed as separated silos.

    Renal cell tumours have a heterogeneous morphology, which may also be changed during tumour progression. Through the use of molecular cytogenetic techniques, it has become possible to divide renal cell tumours into genetically well-defined entities. Papillary renal cell tumours are characterized by loss of the Y chromosome and trisomy of chromosomes 3q, 7, 8, 12, 16, 17 and 20. Non-papillary renal cell carcinomas show a specific loss of chromosome 3p and trisomy of chromosome 5q sequences and frequent loss of chromosome 6q, 8p, 9 and 14q sequences. Chromophobe renal cell carcinomas are marked by a highly specific combination of loss of chromosomes 1, 2, 6, 10, 13, 17 and 21 and gross rearrangement of mitochondrial DNA. Subsets of renal oncocytomas show minimal karyotype alterations or translocation 11q13;? or loss of the Y chromosome and chromosome 1. There are some data suggesting that molecular genetic markers may be used not only for diagnosing of renal cell tumours but also for predicting the prognosis of tumour subtypes. Trisomy of chromosomes 7 and 17 and loss of the Y chromosome marks papillary renal cell adenomas, whereas additional trisomies such as those of chromosomes 3q, 8, 12, 16 and 20 are associated with papillary renal cell carcinomas. Although non-papillary renal cell tumours develop as a carcinoma, their clinical behaviour is in strong correlation with secondary karyotype changes such as loss of chromosomes 6q, 8p, 9 and 14q.

    GLUT-1 has been found to have an important role in the upregulation of various cellular pathways and implicated in neoplastic transformation correlating with biological behavior in malignancies. However, literature regarding the significance of GLUT-1 expression in pancreatic neoplasia has been limited and controversial. Immunohistochemical expression of GLUT-1 was tested in a variety of pancreatic neoplasia including ductal adenocarcinomas (DAs), pancreatic intraepithelial neoplasms (PanINs), intraductal papillary mucinous neoplasms (IPMNs), and serous cystadenomas. There was a progressive increase in the expression of GLUT-1 from low- to higher-grade dysplastic lesions: All higher-grade PanINs/IPMNs (the ones with moderate/high-grade dysplasia) revealed noticeable GLUT-1 expression. Among the 94 DAs analyzed, there were minimal/moderate expression in 46 and significant expression in 24 DAs. However, all 4 clear-cell variants of DAs revealed significant GLUT-1 immunolabeling, as did areas of clear-cell change seen in other DAs. Moreover, all 12 serous cystadenomas expressed significant GLUT-1. GLUT-1 expression was also directly correlated with DA histological grade (P = 0.016) and tumor size (P = 0.03). GLUT-1 may give rise to the distinctive clear-cell appearance of these tumors by inducing the accumulation of glycogen in the cytoplasm. Additionally, because GLUT-1 expression was related to histological grade and tumor size of DA, further studies are warranted to investigate the association of GLUT-1 with prognosis and tumor progression.

    The present work critically analyzes the probabilistic definition of dynamic state-space models subject to Bayesian filters used for monitoring and predicting monotonic degradation processes. The study focuses on the selection of the random process, often called process noise, which is a key perturbation source in the evolution equation of particle filtering. Despite the large number of applications of particle filtering predicting structural degradation, the adequacy of the picked process noise has not been investigated. This paper reviews existing process noise models that are typically embedded in particle filters dedicated to monitoring and predicting structural damage caused by fatigue, which is monotonic in nature. The analysis emphasizes that existing formulations of the process noise can jeopardize the performance of the filter in terms of state estimation and remaining life prediction (i.e., damage prognosis). This paper subsequently proposes an optimal and unbiased process noise model and a list of requirements that the stochastic model must satisfy to guarantee high prognostic performance. These requirements are useful for future and further implementations of particle filtering for monotonic system dynamics. The validity of the new process noise formulation is assessed against experimental fatigue crack growth data from a full-scale aeronautical structure using dedicated performance metrics.

    Recently, technological advances have greatly increased, generating the development of nanotechnology, which is responsible for the design of structures and materials in the nanometer scale. This creates one of the most important cutting-edge sciences, integrating physics, chemistry, engineering and biology sciences. Specifically the integration with biology results in a new science called nanobiotechnology, specifically nanomedicine, which has the goal of mainly looking for more precise molecular diagnostic and prognostic processes, as well as the new design of drugs in the personalized medicine field. On the other hand, at molecular level in medical research, the nanoparticles are most commonly used as tools. Molecular diagnostics uses gold nanoparticles, paramagnetic nanoparticles and quantum dots, which can be used for the diagnosis and treatment of several diseases, including cancer. Quantum dots are the most promising tools for diagnosis and therapy in cancer research.

Despite widespread research and greater public awareness, ASD has an unclear etiology and no known cure, making it difficult to acquire accurate and timely diagnoses. In addition, once an ASD diagnosis is made, parents find it challenging to navigate the healthcare system and determine which interventions are most effective and appropriate for their child. A growing body of evidence supports the value of early diagnosis and treatment with evidence-based interventions, which can significantly improve the quality of life of individuals with ASD as well as of their carers and families. Particularly noteworthy are early interventions that occur in natural surroundings and can be modified to address age-related goals throughout the lifespan. Therefore, the purpose of this review is to: 1 provide readers with a brief background related to ASD; 2 describe commonly used screening instruments and tools for early diagnosis; 3 describe early interventions that have empirical support; and 4 discuss how the parent–child and family relationships can be affected through this process. This information can provide professionals with information they can use to assist families who make critical and potentially life-changing decisions for children with ASD.

    Early detection and treatment is critically important for lung cancer patients. Inflammatory mediators such as IL-6, IL-10, and MCP-1 participate in lung cancer regulation. CEA, CA125, and ProGRP are commonly used serum tumor markers for lung cancer. In this study, we assessed the sensitivity and specificity of CEA, CA125, and ProGRP when used in combination with IL-6, IL-10, and MCP in lung cancer diagnosis. Serum from three different groups (healthy controls, individuals with high risk for lung cancer, and lung cancer patients) was collected. Electrochemiluminescence was used to detect expressions of CEA, CA125, and ProGRP; ELISA was used to examine serum levels of IL-6, IL-10, and MCP-1. Specificity and sensitivity of single as well as combination markers in lung cancer diagnosis were determined. Results indicated that CEA, CA125, ProGRP, and MCP-1 were significantly up-regulated in lung cancer patients as compared to those in controls and high risk individuals. Higher IL-6 and IL-10 levels were observed in both lung cancer patients and high-risk individuals as compared to those in controls. Highest sensitivity (95.2%) in cancer diagnosis was achieved when all six markers were used. This was followed by a combination of IL-6, IL-10, CEA, CA125, and ProGRP (92.6%). The most sensitive (88.6%). Four-marker combination was composed of IL-6, CEA, CA125, and ProGRP. As the combined usage of CEA, CA125, ProGRP, IL-6, IL-10, and MCP-1 significantly improved sensitivity of lung cancer detection; this biomarker arrangement may be beneficial for early diagnosis, treatment, and prognosis of lung cancer.

    Grade II diffuse gliomas (DGs) with isocitrate dehydrogenase (IDH) mutations are associated with better prognosis than their IDH wild-type counterparts. We sought to determine the MRI characteristics associated with IDH mutational status and ascertain whether MRI considered in combination with IDH mutational status can better predict the clinical outcomes of grade II DGs. Preoperative MRI examinations were retrospectively studied for qualitative tumor characteristics, including location, extent, cortical involvement, margin sharpness, cystic component, mineralization or hemorrhage, and contrast enhancement. Quantitative diffusion and perfusion metrics were also assessed. Logistic regression and ROC analyses were used to evaluate the relationship between MRI features and IDH mutational status. The association between IDH mutational status, 1p19q codeletion, MRI features, extent of resection, and clinical outcomes was assessed by Kaplan-Meier and Cox proportional hazards models. Of 100 grade II DGs, 78 were IDH mutant and 22 were IDH wild type. IDH wild-type tumors were associated with older age, multifocality, brainstem involvement, lack of cystic change, and a lower apparent diffusion coefficient (ADC). Multivariable regression showed that age older than 45 years as well as low minimum ADC (ADC min ), mean ADC, and maximum ADC values were independently associated with IDH mutational status. Of these, an ADC min threshold of 0.9 × 10 -3 mm 2 /s or less provided the greatest sensitivity and specificity (91% and 76%, respectively) in defining IDH wild-type grade II DGs. Combining low ADC min with IDH wild-type status conferred worse outcomes than did IDH wild-type status alone. IDH wild-type grade II DGs are associated with a lower ADC and poor clinical outcomes. Combining IDH mutational status and ADC may allow more accurate prediction of clinical outcomes for patients with grade II DGs.

    Full Text Available Abstract Objective Glioblastoma multiforme (GBM is a highly malignant brain tumor with a poor prognosis. MicroRNAs (miRNAs are a class of small non-coding RNAs, approximately 21–25 nucleotides in length. Recently, some researchers have demonstrated that plasma miRNAs are sensitive and specific biomarkers of various cancers. The primary aim of the study is to investigate whether miRNAs present in the plasma of GBM patients can be used as diagnostic biomarkers and are associated with glioma classification and clinical treatment. Materials and Methods Plasma samples were attained by venipuncture from 50 patients and 10 healthy donors. Plasma levels of miRNAs were determined by real-time quantitative polymerase chain reaction. Results The plasma levels of miR-21, miR-128 and miR-342-3p were significantly altered in GBM patients compared to normal controls and could discriminate glioma from healthy controls with high specificity and sensitivity. However, these three miRNAs were not significantly changed in patients with other brain tumors such as meningioma or pituitary adenoma. Furthermore, the plasma levels of these three miRNAs in GBM patients treated by operation and chemo-radiation almost revived to normal levels. Finally, we also demonstrated that miR-128 and miR-342-3p were positively correlated with histopathological grades of glioma. Conclusions These findings suggest that plasma specific miRNAs have potential use as novel biomarkers of glioma and may be useful in clinical management for glioma patients.

    Full Text Available Brucella spp. are facultative intracellular Gram negative bacteria with specific tropism for monocytes/macrophages. Clinical manifestations of brucellosis are primarily immune-mediated and not thought to be due to bacterial virulence factors. Acquired immunity to brucellosis has been studied through observations of naturally infected hosts (cattle, goats, laboratory mouse models, and human infection. Cell-mediated immunity drives the clinical manifestations of human disease after exposure to Brucella species but high antibody responses are not associated with protective immunity. The precise mechanisms by which cell-mediated immune responses confer protection or lead to disease manifestations remain poorly understood. Descriptive studies of immune responses in human brucellosis show that TH1 (interferon-gamma are associated with dominant immune responses, findings consistent with animal studies. Whether these T cell responses are protective, or determine the different clinical responses associated with brucellosis is unknown, especially with regard to undulant fever manifestations, relapsing disease, or are associated with responses to distinct sets of Brucella spp. antigens are unknown. Few data regarding T cell responses in terms of specific recognition of Brucella spp. protein antigens and peptidic epitopes, either by CD4+ or CD8+ T cells, have been identified in human brucellosis patients. Additionally because current attenuated Brucella vaccines used in animals cause human disease, there is a true need for a recombinant protein subunit vaccine for human brucellosis, as well as for improved diagnostics in terms of prognosis and identification of unusual forms of brucellosis. This review will focus on current understandings of antigen-specific immune responses induced by Brucella protein antigens that has promise for yielding new insights into vaccine and diagnostics development, and for understanding pathogenetic mechanisms of human

  7. Preclinical diagnosis of Alzheimer's disease: Prevention or prediction?

    Directory of Open Access Journals (Sweden)

    Ricardo Nitrini

    Full Text Available Abstract The diagnosis of Alzheimer's disease (AD for cases with dementia may be too late to allow effective treatment. Criteria for diagnosis of preclinical AD suggested by the Alzheimer's Association include the use of molecular and structural biomarkers. Preclinical diagnosis will enable testing of new drugs and forms of treatment toward achieving successful preventive treatment. But what are the advantages for the individual? To know that someone who is cognitively normal is probably going to develop AD's dementia when there is no effective preventive treatment is definitely not good news. A research method whereby volunteers are assigned to receive treatment or placebo without knowing whether they are in the control or at-risk arm of a trial would overcome this potential problem. If these new criteria are used wisely they may represent a relevant milestone in the search for a definitive treatment for AD.

    Congenital cytomegalovirus infection is a major cause of central nervous system and sensory impairments that affect cognition, motor function, hearing, language development, vestibular function, and vision. Although the importance of congenital cytomegalovirus infection is readily evident, the vast majority of maternal and fetal infections are not identified, even in developed countries. Multiple studies of prenatal cytomegalovirus infections have produced a body of knowledge that can inform the clinical approach to suspected or proven maternal and fetal infection. Reliable diagnosis of cytomegalovirus infection during pregnancy and accurate diagnosis of fetal infection are a reality. Approaches to preventing the transmission of cytomegalovirus from mother to fetus and to the treatment of fetal infection are being studied. There is evidence that public health approaches based on hygiene can dramatically reduce the rate of primary maternal cytomegalovirus infections during pregnancy. This review will consider the epidemiology of congenital cytomegalovirus infection, the diagnosis and management of primary infection during pregnancy, and approaches to preventing maternal infection.

A reduction in mortality was achieved by low-dose computed tomography screening of high-risk patients. However, the benefit was later challenged by the high false positive rate, resulting in unnecessary follow-ups, thus entailing a burden on both the health care system and the individual. The diagnostic dilemma imposed by imaging modalities has created a need for the development of biomarkers capable of differentiating benign nodules from malignant ones. In the past decade, with the advancements in high-throughput profiling technologies, a huge amount of work has been done to derive biomarkers to supplement clinical diagnosis. However, only a few of them have efficient sensitivity and specificity to be utilized in clinical settings. Therefore, there is an urgent need for the development of sensitive and specific means to detect and diagnose lung cancers at an early stage, when curative interventions are still possible. Due to the invasiveness of tissue biopsies and inability to capture tumor heterogeneity, nowadays enormous efforts have been invested in the development of technologies and biomarkers that enable sensitive and cost-effective testing using substrates that can be obtained in a noninvasive manner. This review, primarily focusing on liquid biopsy, summarizes all documented potential biomarkers for diagnosis, monitoring recurrence treatment response. Keywords

  12. Bone metastases of differentiated thyroid cancer: the importance of early diagnosis and 131I therapy on prognosis

    2008-01-01

    Complete text of publication follows: Distant metastases are found at diagnosis or during follow-up in 10%-15% of patients with differentiated thyroid cancer. Bone is the second most commonly involved site. Patients with bone metastases, whether isolated or associated with lung metastases, have a markedly poor prognosis. Ten-year survival rates range from 13% to 21%. Given such poor prognosis, the use of 131 I therapy has been questioned. However, it might well be that poor prognosis of bone metastases can be overcome if 131 I therapy is delivered at an early stage, when tumor burden is small, as previously demonstrated for pulmonary metastases. A review of a large series of patients showed that only rarely were bone metastases diagnosed at an early stage. Among 109 patients with bone metastases reported by Bernier et al., only 4 had both radioiodine uptake and a negative standard radiography examination. Similarly, Durante et al. reported that only 8 of 115 patients had negative radiography findings at presentation. Prognosis may improve if bone metastases are detected earlier. In a recent study, bone metastases were first detected by 131 I scanning in 8 of 16 patients, when complementary radiologic studies were negative. Six of these patients showed an excellent response to 131 I therapy. Today, the nuclear medicine community is well armed for this challenge toward earlier diagnosis. Postsurgery thyroid remnant ablation is more widely used. The 131 I whole body scan associated with thyroid remnant ablation after thyroidectomy has a major role in early diagnosis of functioning distant metastases at a time when complementary imaging techniques (CT, MRI, bone scanning) are often still showing negative findings. Early diagnosis of specific 131 I-avid bone foci will be improved with the advent and generalization of SPECT/CT. When early diagnosis is achieved, repeated 131 I therapy can be effective by targeting not only visible metastases but also those still too small

    Alzheimer's disease (AD) is the most common form of dementia affecting seniors age 65 and over. When AD is suspected, the diagnosis is usually confirmed with behavioural assessments and cognitive tests, often followed by a brain scan. Advanced medical imaging is a good tool to predict conversion from prodromal stages (mild cognitive impairment) to Alzheimer's disease. Since volumetric MRI can detect changes in the size of brain regions, measuring those regions that atrophy during the progress of Alzheimer's disease can help the neurologist in his diagnostic. In the present investigation, we present an automatic tool that reads volumetric MRI and performs 2-dimensional (volume slices) and volumetric segmentation methods in order to segment gray matter, white matter and cerebrospinal fluid (CSF). We used the MRI data sets database from the Open Access Series of Imaging Studies (OASIS).

    2014-06-01

    In Western society and increasingly elsewhere, death has become medicalised and 'hospitalised' even when people are enduring deteriorating terminal conditions such as dementia and heart failure. In an attempt to rationalise and dignify the place and manner of death, evidence is emerging that the adoption of end-of-life care pathways and models can improve the experience of the end-of-life care across a range of care settings. Each of these demands skills and knowledge in the assessment and prediction of the dying trajectory. In this study, we report complexities facing relatives, residents and nursing home staff in the awareness, diagnosis and prediction of the dying trajectory. Data were collected and analysed within a broadly qualitative methodology. The contexts were two nursing homes in the Greater Manchester area, each at different stages of implementing 'Gold Standards Framework' approaches to planning end-of-life care with residents and their relatives. From 2008 to 2011 and with appropriate consent, data were collected by a mixture of interviews and participant observation with residents, relatives and staff. Appropriate ethics approvals were sought and given. Key emerging themes were diagnosis and awareness of dying in which there is no substitute for experience. Significant resource is needed to engage staff, residents and relatives/carers with the idea of advance care planning. Talking to residents and relatives about their feelings and wishes for care at the end of life remains especially difficult, but education and training in key skills and knowledge can engender confidence. Challenges include diagnosing and predicting dying trajectories. Advance care planning can reduce the distress from and number of inappropriate hospital admissions, but requires determination and consistent application of the approach. This can be very challenging in the face of staff rotation and the unpredictability both of the dying trajectory and the decision-making of some

    Current blood biomarkers are suboptimal in detecting drug-induced liver injury (DILI) and predicting its outcome. We sought to characterize the natural variabilty and performance characteristics of fourteen promising DILI biomarker candidates. Serum or plasma from multiple cohorts of healthy volunteers (n=192 and =81), subjects who safely took potentially hepatotoxic drugs without adverse effects (n=55 and =92) and DILI patients (n=98, =28, and =143) were assayed for microRNA-122 (miR-122), glutamate dehydrogenase (GLDH), total keratin 18 (K18), caspase cleaved K18 (ccK18), glutathione S-transferase alpha (GSTα), alpha fetoprotein (AFP), arginase-1 (ARG1), osteopontin (OPN), sorbitol dehydrogenase (SDH), fatty acid binding protein (FABP1), cadherin-5 (CDH5), macrophage colony stimulating factor receptor (MCSFR), paraoxonase 1 (PON1, normalized to prothrombin protein), and leucocyte cell-derived chemotaxin-2 (LECT2). Most candidate biomarkers were significantly altered in DILI cases compared to healthy volunteers. GLDH correlated more closely with gold standard alanine aminotransferase (ALT) than miR-122 and there was a surprisingly wide inter- and intra-individual variability of miR-122 levels among the healthy volunteers. Serum K18, OPN, and MCSFR levels were most strongly associated with liver-related death or transplant within 6 months of DILI-onset. Prediction of prognosis among DILI patients using Model for End-stage Liver Disease (MELD) was improved by incorporation of K18 and MCSFR levels. GLDH appears to be more useful than miR-122 in identifying DILI patients. K18, OPN and MCSFR are promising candidates for prediction of prognosis during an acute DILI event. Serial assessment of these biomarkers in large prospective studies will help further delineate their role in DILI diagnosis and management. This article is protected by copyright.

    Full Text Available The article presents the literature data on the incidence, the main clinical manifestations, modern methods for early neonatal and postnatal diagnosis and treatment of ventricular septal defect in children, as well as the prognosis of this disease. According to the International Classification of Diseases, 10th revision, ventricular septal defect is classified as Q21.0 Ventricular septal defect. Incidence. In the overall structure of congenital malformations of the cardiovascular system, ventricular septal defect has about 20 %. Diagnosis. Moderate ventricular septal defect is manifested by shortness of breath, rapid fatigability during feeding, delay in physical development. Significant arterial-venous shunt in the first month of life is accompanied by a transient mild cyanosis when the baby is fed and cries. Infants develop high pulmonary hypertension, circulatory failure, malnutrition. Small noise intensity is typical for newborns in the first weeks or even months of life, which is due to physiologically increased intravascular pulmonary resistance. Systolic murmur is extended to the entire systole with maximum amplitude at the left edge of the sternum at the level of III–IV intercostal spaces. Sclerotic phase of pulmonary hypertension with ventricular septal defect is defined as Eisenmenger reaction. The clinical picture of this disorder depends on the degree of hemodynamic instability caused by the defect parameters, the pressure level in the pulmonary artery, vascular pulmonary resistance, the magnitude and direction of the shunt through the defect. Diagnosis is confirmed by characteristic changes in the electrocardiogram, echocardiography and chest radiograph. Treatment. Small muscular ventricular septal defects often close spontaneously during the first 2 years of life. Drug correction is needed in the development of congestive heart failure. The optimum age for surgery — 5–9 years.

    Full Text Available Accurate diagnosis of Takotsubo Cardiomyopathy has substantial prognostic implications in an intensive care unit, given its increased mortality risk and association with life-threatening complications. This report seeks to discuss diagnostic modalities that can be useful in accurately differentiating Takotsubo Cardiomyopathy from Acute Coronary Syndrome, and also briefly discuss prevention and management of this cardiomyopathy in an intensive care unit. For critically ill Takotsubo patients, intensive clinicians can consider establishment of diagnosis by specific electrocardiograph changes, distinctive marked release of cardiac enzymes, characteristic echocardiograph findings, as well as invasive coronary angiography or noninvasive cardiac magnetic imaging.

    Melanotic Schwannoma (MS) is rarely seen and potentially malignant neoplasm that is categorized as a variant of Schwannoma. MS most frequently involves intracranial structures followed by posterior nerve roots in the spinal canal. Approximately 50% of the cases with MS have psammomatous calcifications and this type of MS is related to Carney complex with autosomal dominant inheritance. Most cases of MS are benign, though 10% of them are malignant with metastatic potential. MS mimics melanoma and the differential diagnosis should be made excluding other melanin producing neoplasms especially melanoma. Case 1 . A 42-year-old hypertensive male presented for checkup. He had a well-defined extraspinal oval lesion measuring 3.5 × 2.5 cm near right adrenal. Case 2 . A 22-year-old female presented with neurofibromatosis-2, bilateral acoustic schwannomas and café au lait lesions on sacrococcygeal region. She had an intradural extramedullary lesion measuring 6.1 × 2.0 cm at L1-2 level. MS is a rare neoplasm composed of Schwann cells and melanin pigment. These tumors are usually benign but they may become aggressive. The biologic behavior of MS is difficult to predict; the patients have to be followed up for a longer period due to its malignant potential.

    Cervical spine injuries are a common occurrence in multi-trauma patients and should be taken into account when planning further clinical management. This review describes in detail upper and lower cervical spine injuries and introduces the sub-axial injury classification (SLIC) that is based on three components: injury morphology, integrity of the discoligamentous complex and the neurologic status of the patient. If the total SLIC score is <3, non-surgical treatment is recommended. If the total is {>=}5, operative treatment is indicated as such a score is associated with instability and probably neurologic deficits. The precise diagnosis of the radiologist, which would include the SLIC classification, should facilitate clinical decision-making about further management. (orig.) [German] Halswirbelsaeulenverletzungen sind bei polytraumatisierten Patienten haeufig und sollten beim klinischen Management des Patienten beruecksichtigt werden. Verletzungen der oberen Halswirbelsaeule werden als Sonderformen eingeteilt. Die subaxialen Verletzungen koennen nach der SLIC-Klassifikation ('sub-axial injury classification') gescort werden, die auf der Morphologie der Verletzung, dem diskoligamentaeren Komplex und dem neurologischen Status basiert. Bei einem Score <3 wird ein konservatives Management empfohlen. Bei einem Score {>=}5 sollte eine operative Versorgung der Halswirbelsaeule vorgenommen werden, da die Verletzung eine Instabilitaet und moeglicherweise auch ein neurologisches Defizit verursacht. Anhand einer praezisen Diagnose des Radiologen unter Beruecksichtigung der SLIC-Klassifikation sollte dem Kliniker die Entscheidung fuer das weitere Management erleichtert werden. (orig.)

    There is an urgent need for further studies evaluating the role of imaging modalities in the management of left ventricular assist device (LVAD) thrombosis. This study reviews the role of computed tomography (CT) in the diagnosis of suspected LVAD thrombosis. All contrast chest CTs performed in patients with suspected LVAD thrombosis at the University of Minnesota between January 2008 and April 2014 were reviewed. Significant CT findings were identified, operative notes were reviewed, and patient outcomes were reported. A total of 32 contrast chest CT examinations were performed in 24 patients with suspected LVAD thrombosis. LVAD thrombus was identified on CT in two patients (one in the outflow graft and one in the inflow cannula), and complications were found in two patients (one with inflow cannula malposition and one with outflow graft stenosis at aortic anastomosis site). Thirteen patients (67%) underwent LVAD explantation for clinically presumed LVAD thrombosis (LVAD exchange in seven, orthotopic heart transplant in six). LVAD thrombus was confirmed at the time of surgery in eight patients (62%; six in the motor, two in the outflow graft). CT has a low sensitivity but high specificity for detecting LVAD thrombus. The sensitivity is higher, but still modest for the detection of thrombus in the outflow cannula. © 2017 Wiley Periodicals, Inc.

    Treatment and outcome of infant acute leukemia (IAL) in developed countries have been well documented. However, reports summarizing diagnosis and outcome of IAL in developing countries are limited. Five hundred ninety seven pediatric patients were diagnosed with acute leukemia in our hospital between January 1997 and June 2008, of which 19 were younger than 12 months. Data from our 19 cases and the Chinese literature were analyzed. Of the 19 cases, 14 had acute lymphoblastic leukemia (ALL) and 5 had acute myeloid leukemia (AML) based on FAB classification. Immunophenotyping and molecular genetic analysis were performed in only 6 cases. Only 16% (3/19) of the infants received treatment. Two infants with immunophenotypic AML who abandoned treatment achieved spontaneous remission without chemotherapy within 2 and 4 months respectively. Combining our data with those from Chinese literature, less than one third of the infants had immunophenotypic and genetic verification of leukemia and 29% (18/63) of them received treatment. Family financial difficulties and physicians' lack of confidence in treatment outcome in IAL contributed to a high treatment abandonment rate and poor outcome. Public health insurance as well as physician education on current IAL treatment strategies may decrease treatment abandonment in China.

    Lichen planus (LP) is a chronic inflammatory disorder that most often affects middle-aged adults. LP can involve the skin or mucous membranes including the oral, vulvovaginal, esophageal, laryngeal, and conjunctival mucosa. It has different variants based on the morphology of the lesions and the site of involvement. The literature suggests that certain presentations of the disease such as esophageal or ophthalmological involvement are underdiagnosed. The burden of the disease is higher in some variants including hypertrophic LP and erosive oral LP, which may have a more chronic pattern. LP can significantly affect the quality of life of patients as well. Drugs or contact allergens can cause lichenoid reactions as the main differential diagnosis of LP. LP is a T-cell mediated immunologic disease but the responsible antigen remains unidentified. In this paper, we review the history, epidemiology, and clinical subtypes of LP. We also review the histopathologic aspects of the disease, differential diagnoses, immunopathogenesis, and the clinical and genetic correlations. PMID:24672362

    Abstract Lung carcinogenesis is a complex process requiring the acquisition of genetic mutations that confer the malignant phenotype as well as epigenetic alterations that may be both manipulated in the course of therapy. Aberrant gene function and transcriptional silencing by CpG island hypermethylation has become a critical component in the initiation and progression of lung cancer. Growing evidence shows that acquired epigenetic abnormalities participate with genetic alterations to cause this dysregulation. Human and animal studies have fostered significant advances in elucidating the role of gene-specific methylation in cancer initiation and progression, the modulation of DNA methylation by carcinogen exposure and the ability of pharmacologic agents to reverse promoter hypermethylation, making it an attractive target to pursue for prevention of lung cancer. This review focuses on how lung cancer predisposing factors participate in epigenetic alterations of lung neoplasia, and discusses the growing implications of these alterations for strategies to control cancer.

    Cytomegalovirus is the most common congenital infection causing serious disease in infants. It is the leading infectious cause of sensorineural hearing loss and neurodevelopmental disability in developed countries. Despite the clinical importance of congenital cytomegalovirus, surveys show there is limited awareness and knowledge in the medical and general community about congenital cytomegalovirus infection. This article reviews the clinical features, global epidemiology, transmission and risk factors for cytomegalovirus infections. It also highlights several major advances made in recent years in the diagnosis and prevention of cytomegalovirus infection during pregnancy. Although research is ongoing, no therapy is currently proven to prevent or treat maternal, fetal or neonatal cytomegalovirus infection. Education of women regarding hygiene measures can help prevent cytomegalovirus infection and are currently the best strategy to prevent congenital cytomegalovirus disease.

    Aim: The objective of this investigation was to establish the usefulness of ECD-99mTc brain perfusion SPECT in the evaluation of the diagnosis of functional alterations of Vascular Headaches of migrainous origin and to determine the changes in regional cerebral blood flow (FSCr) during the headache phase. Material and Methods: A population of 21 female patients, 5 controls, of the same age and sex, aged between 20 and 76 years, with clinical evidence of headache with or without aura, with a duration of 8 to 72 hours, pulsating pain, associated to nausea, photophobia, phonophobia, that does not resolve with common analgesics and characterized by increase of the pain with physical activity. Brain perfusion SPECT was practiced on them at the moment of crisis, independent of the presence of aura or pain, and without crisis. ECD-99mTc was administered at a dose of 925 to 1110 MBq. Images were analyzed by the semi quantification method. Results: SPECT detected 13 hypo-captures on the 16 patients studied. With an 81% sensitivity and 100% specificity, with a precision value of 86%. Analysis through X Binomial Aleatory Variable showed a precision of 90% (p= < 0,023) for the isotopic test, with a significance level of 5%. Conclusions: The results of this study confirm that brain SPECT is a neuroimaging technique capable of identifying migrainous patients, being able to reevaluate the type of hypo perfusion that each patient has, during crisis or out of crisis, and correlate the cortical perfusion deficits and the deterioration of neuropsychological functions

    The relationship between depressive symptoms and other symptom categories in schizophrenia have been studied by many authors. According to the existing studies depression in schizophrenic patients is related to the presense of positive symptoms, especifically delusions and hallucinations.As far as negative symptoms concerns it seems that there coexist with the depressive symptoms in any phase of the disease at least in a subgroup of schizophrenic patients. In addition, according to the pyramidal model of Kay, when positive and depressive symptoms coexist, they create theclinical picture of the paranoid subtype of schizophrenia. The same holds for the combination of negative and depressive symptoms, which most frequently describe the residual subtype of the disease. Extrapyramidal symptoms are side effects of antipsychotic drugs (especially the classicalones). According to the existing literature it seems that antipyramidal side effects appear more often in schizophrenic patients with depressive symptoms. The differential diagnosis of depressive symptoms in schizophrenic patients should start with the evaluation of possible presence of organiccauses like somatic disease, medication induced extrapyramidal symptoms, substance abuse. Yet, symptoms of depression need to be differentiated from the negative symptoms of schizophrenia. Psychiatric syndromes like schizoaffective disorder, bipolar disorder and depression with psychotic features need to be also considered. In this case is very important to identify accurately the duration of depressive symptoms as well as the succession of appearance of the depressive vs. psychotic symptoms. Depressive symptoms appear to be bad prognostic sign for the long-term outcome of schizophrenia, because of the increased risk for suicide but also because of the worsening of the quality of life and the general wellbeing of the schizophrenic patient. Depressive symptoms during the acute phase of the disease usually respond to

    Full Text Available Small bowel volvulus is a rare disease, which is also challenging to diagnose. The aims of this study were to characterize the clinical and radiological features associated with small bowel volvulus and treatment and to identify risk factors for associated small bowel necrosis.Patients with small bowel volvulus who underwent operations from January 2001 to December 2015 at the First Affiliated Hospital of China Medical University (Shenyang, China were reviewed. Clinical, surgical and postsurgical data were registered and analyzed.Thirty-one patients were included for analysis. Fifteen patients were female (48.4%, with an average age of 47.7 years (18-79 years. The clinical signs and symptoms were unspecific and resembled intestinal obstruction. Clinical examination revealed abdominal distension and/or diffuse tenderness with or without signs of peritonitis. The use of CT scans, X-rays or ultrasound did not differ significantly between patients. In 9 of 20 patients that received abdominal CT scans, "whirlpool sign" on the CT scan was present. Secondary small bowel volvulus was present in 58.1% of patients, and causes included bands (3, adhesion (7, congenital anomalies (7 and stromal tumor (1. Out of the 31 patients, 15 with gangrenous small bowel had to undergo intestinal resection. Intestinal gangrene was present with higher neutrophils count (p<0.0001 and the presence of bloody ascites (p = 0.004. Three patients died of septic shock (9.68%, and the recurrence rate was 3.23%.To complete an early and accurate diagnosis, a CT scan plus physical exam seems to be the best plan. After diagnosis, an urgent laparotomy must be performed to avoid intestinal necrosis and perforation. After surgery, more than 90% of the patients can expect to have a favorable prognosis.

    Cancer cells secrete factors that influence adjacent cell behavior and can lead to enhanced proliferation and metastasis. To better understand the role of these factors in oncogenesis and disease progression, estrogen and progesterone receptor positive MCF-7 cells, triple negative breast cancer MDA-MB-231, DT22, and DT28 cells, and MCF-10A non-transformed mammary epithelial cells were grown in 3D cultures. A special emphasis was placed on triple negative breast cancer since these tumors are highly aggressive and no targeted treatments are currently available. The breast cancer cells secreted factors of variable potency that stimulated proliferation of the relatively quiescent MCF-10A cells. The conditioned medium from each cell line was subjected to mass spectrometry analysis and a variety of secreted proteins were identified including glycolytic enzymes, proteases, protease inhibitors, extracellular matrix proteins, and insulin-like growth factor binding proteins. An investigation of the secretome from each cell line yielded clues about strategies used for breast cancer proliferation and metastasis. Some of the proteins we identified may be useful in the development of a serum-based test for breast cancer detection, diagnosis, prognosis, and monitoring.

    The psychological and behavioural symptoms of dementia (BPSD) [corrected] give rise to personal suffering, are the cause of added deterioration and worsen the economic and social cost of dementias. To offer a systematic approach to the prevention, diagnosis and treatment of BPSD. [corrected]. The study adopts a global perspective that takes into account biological, psychological and social factors in an attempt to avoid both excessive medicalisation and a purely psychology-based attitude. Satisfying basic needs, treating medical and psychiatric comorbidity, the adaptation of the setting, and the specific pharmacological treatment of dementia, as well as offering patients and their caregivers the counselling and support they need, all contribute to prevent the onset of BPSD. [corrected]. The diagnosis of BPSD [corrected] is based on the patient's medical history and on observation. It is useful to identify a primary or destabilising BPSD [corrected] on which to deploy hypotheses and specific treatments based on modifying the environment, drugs, non-pharmacological therapies and continuous assessment. Any action taken must be integrated within a person-focused care plan aimed at accomplishing the patients' and their caregivers' welfare and quality of life. BPSD [corrected] are the result of biological, psychological and social factors. In the present scenario, in which there are no curative treatments in most cases of dementia, a systematic and multidisciplinary approach aimed at preventing and treating BPSD [corrected] is a highly cost-effective therapeutic opportunity in both personal and social terms.

    Candidiasis is the most common opportunistic yeast infection. Candida species and other microorganisms are involved in this complicated fungal infection, but Candida albicans continues to be the most prevalent. In the past two decades, it has been observed an abnormal overgrowth in the gastrointestinal, urinary and respiratory tracts, not only in immunocompromised patients, but also related to nosocomial infections and even in healthy individuals. There is a widely variety of causal factors that contribute to yeast infection which means that candidiasis is a good example of a multifactorial syndrome. Due to rapid increase in the incidence in these infections, this is the subject of numerous studies. Recently, the focus of attention is the treatment and, above all, the prevention of those complications. The diagnosis of candidiasis could become quite complicated. Prevention is the most effective "treatment," much more than eradication of the yeast with antifungal agents. There are several aspects to consider in the daily routine that can provide a strength protection. However, a therapeutic approach is necessary when the infection is established, and therefore, other alternatives should be explored. This review provides an overview on predisposition factors, prevention and diagnosis of candidiasis, highlighting alternative approaches for candidiasis treatment.

    Prediction models are developed to aid health care providers in estimating the probability or risk that a specific disease or condition is present (diagnostic models) or that a specific event will occur in the future (prognostic models), to inform their decision making. However, the overwhelming evidence shows that the quality of reporting of prediction model studies is poor. Only with full and clear reporting of information on all aspects of a prediction model can risk of bias and potential usefulness of prediction models be adequately assessed. The Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis (TRIPOD) Initiative developed a set of recommendations for the reporting of studies developing, validating, or updating a prediction model, whether for diagnostic or prognostic purposes. This article describes how the TRIPOD Statement was developed. An extensive list of items based on a review of the literature was created, which was reduced after a Web-based survey and revised during a 3-day meeting in June 2011 with methodologists, health care professionals, and journal editors. The list was refined during several meetings of the steering group and in e-mail discussions with the wider group of TRIPOD contributors. The resulting TRIPOD Statement is a checklist of 22 items, deemed essential for transparent reporting of a prediction model study. The TRIPOD Statement aims to improve the transparency of the reporting of a prediction model study regardless of the study methods used. The TRIPOD Statement is best used in conjunction with the TRIPOD explanation and elaboration document. To aid the editorial process and readers of prediction model studies, it is recommended that authors include a completed checklist in their submission (also available at www.tripod-statement.org). © 2015 The Authors.

    Point-of-care tools are needed in sub-Saharan Africa (SSA) to improve pediatric Burkitt lymphoma (BL) diagnosis and treatment. We evaluated plasma Epstein-Barr virus (pEBV) DNA as a pediatric BL biomarker in Malawi. Prospectively enrolled children with BL were compared to classical Hodgkin lymphoma (cHL) and nonlymphoma diagnoses. Pediatric BL patients received standardized chemotherapy and supportive care. pEBV DNA was measured at baseline, mid-treatment, and treatment completion. Of 121 assessed children, pEBV DNA was detected in 76/88 (86%) with BL, 16/17 (94%) with cHL, and 2/16 (12%) with nonlymphoma, with proportions higher in BL versus nonlymphoma (p < 0.001) and similar in BL versus cHL (p = 0.69). If detected, median pEBV DNA was 6.1 log 10 copies/mL for BL, 4.8 log 10 copies/mL for cHL, and 3.4 log 10 copies/mL for nonlymphoma, with higher levels in BL versus cHL (p = 0.029), and a trend toward higher levels in BL versus nonlymphoma (p = 0.062). pEBV DNA declined during treatment in the cohort overall and increased in several children before clinical relapse. Twelve-month overall survival was 40% in the cohort overall, and for children with baseline pEBV detected, survival was worse if baseline pEBV DNA was ≥6 log 10 copies/mL versus <6 log 10 copies/mL (p = 0.0002), and also if pEBV DNA was persistently detectable at mid-treatment versus undetectable (p = 0.041). Among children with baseline pEBV DNA detected, viremia was the only significant risk factor for death by 12 months in multivariate analyses (adjusted hazard ratio 1.35 per log 10 copies/mL, 95% CI 1.04-1.75, p = 0.023). Quantitative pEBV DNA has potential utility for diagnosis, prognosis, and response assessment for pediatric BL in SSA. © 2017 UICC.

    Postoperative pulmonary edema is a well-known postoperative complication caused as a result of numerous etiological factors which can be easily detected by a careful surveillance during postoperative period. However, there are no preoperative and intraoperative criteria which can successfully establish the possibilities for development of postoperative pulmonary edema. The aims were to review the possible etiologic and diagnostic challenges in timely detection of postoperative pulmonary edema and to discuss the various management strategies for prevention of this postoperative complication so as to decrease morbidity and mortality. The various search engines for preparation of this manuscript were used which included Entrez (including Pubmed and Pubmed Central), NIH.gov, Medknow.com, Medscape.com, WebMD.com, Scopus, Science Direct, MedHelp.org, yahoo.com and google.com. Manual search was carried out and various text books and journals of anesthesia and critical care medicine were also searched. From the information gathered, it was observed that postoperative cardiogenic pulmonary edema in patients with serious cardiovascular diseases is most common followed by noncardiogenic pulmonary edema which can be due to fluid overload in the postoperative period or it can be negative pressure pulmonary edema (NPPE). NPPE is an important clinical entity in immediate post-extubation period and occurs due to acute upper airway obstruction and creation of acute negative intrathoracic pressure. NPPE carries a good prognosis if promptly diagnosed and appropriately treated with or without mechanical ventilation.

The initial onset of 10 children was at night, whereas 2 began with absence seizure in lucid interval, and they gradually appeared comprehensive brain function decline, meanwhile, ECG was characterized by continuous discharge during slow wave sleep. After 3 months of treatment with valproic acid, clonazepam, lamotrigine and hormones, the clinical symptoms and ECG of 10 children improved significantly, in which 3 ones recurred after 6 months of comprehensive treatment. Conclusion: The early manifestation of CSWS is untypical, and hence, early diagnosis and treatment can ameliorate the epileptic seizures of children, effectively inhibit epileptic electrical activity and has favorable prognosis.

    Full Text Available Angela Di Cesare, Donato Traversa Faculty of Veterinary Medicine, University of Teramo, Teramo, Italy Abstract: Angiostrongylus vasorum is a parasitic nematode affecting the heart and pulmonary arteries of wild (eg, foxes and domestic canids. The parasite has an indirect life cycle in which slugs and snails act as intermediate hosts. In the last few years the parasite has spread outside the traditional endemic foci, and there is a rise of documented cases of canine angiostrongylosis across Europe. Angiostrongylus vasorum causes cardiopulmonary disorders and coagulopathies, along with different nonspecific clinical signs. Fatal infections are frequently reported. Given the severity of the infection and the recent geographic spreading of the parasite, this article reviews and discusses the current knowledge of A. vasorum, with a special focus on recent insights on diagnosis, prevention, and treatment of dog angiostrongylosis. Keywords: Angiostrongylus vasorum, dog, epidemiology, diagnostic approaches, control, therapy

    Full Text Available The aim of this study is to assess the psychosocial risks of university teachers and identify enhancement areas for a healthy organization in a sample of 621 teachers from the University of A Coruña, Spain. To achieve this aim, the Copenhagen Psychosocial Questionnaire (CoPsoQ adapted to the Spanish population (ISTAS21 Method was applied. The results showed an unfavorable situation for psychosocial health in five dimensions: high psychological demands, low esteem, high double presence, low social support, and high job insecurity. In contrast, a favorable situation for health is the dimension active work and development opportunities. It was also found that there is not a single profile of university teacher in psychosocial risk. To conclude, a diagnosis of psychosocial risks of university teachers is made and, in that scenario, some risk prevention strategies at university level are proposed.

    Full Text Available to improve treatment results in premature infants with neonatal respiratory distress syndrome (NRDS, by establishing developmental mechanisms and elaborating methods for its early diagnosis, treatment, and prevention. Material and methods. The paper analyzes the results of a clinical observation and laboratory, instrumental, immunological, morphological, and radiological studies of 320 premature neonates at 26—35 weeks gestational age. The following groups of neonates were identified: 1 40 premature neonatal infants without NRDS and with the physiological course of an early neonatal period (a comparison group; 2 190 premature neonates with severe NRDS in whom the efficiency of therapy with exogenous surfactants, such as surfactant BL versus curosurf, was evaluated; 3 90 premature newborn infants who had died from NRDS at its different stages. Results. The poor maternal somatic, obstetric, and gynecological histories in the early periods of the current pregnancy create prerequisites for its termination, favor the development of severe acute gestosis, and cause abnormal placental changes. Each gestational age is marked by certain placental changes that promote impaired uterineplacentalfetal blood flow and premature birth. Alveolar and bronchial epithelial damages, including those ante and intranatally, microcircula tory disorders play a leading role in the tanatogenesis of NRDS. Intranatal hypoxia and amniotic fluid aspiration are one of the important factors contributing to alveolar epithelial damage and NRDS in premature neonates. Exogenous surfactants prevent the development of hyaline membranes and are useful in the normalization of ventilation-perfusion relationships and lung biomechanical properties. Conclusion. This study could improve the diagnosis and treatment of NRDS, which assisted in reducing the duration of mechanical ventilation from 130±7.6 to 65±11.6 hours, the number of complications (the incidence of intragastric

    Deafness is a global problem. In India deafness ranges from 4 % in urban to 11 % in rural and slum areas, out of which 50 % is conductive hearing loss hence curable. Genetic transmission accounts for 50 % of the cases of congenital deafness, and of these, around 30 % are syndromic and 70 % are non-syndromic. Genetic counseling is going to make aware the parents of all appropriate treatments. Preimplantation genetic diagnosis can help to have a baby free from genetic deafness. Procedure is almost safe, harmless, non-invasive and ethically acceptable. While Amniocentesis is a non-invasive method, prenatal genetic testing through Chorionic villous sampling is invasive. The connexin 26 (CX26W 24X) mutations are the most common cause of non-syndromic hearing loss and easy to identify by polymerase chain reaction. There is always co-morbidity after cochlear implantation and the person remains handicapped while baby after PGD shall be having healthy normal life and person prone to environmental factors may be counseled and guided to prevent deafness in next generation. Public must be made aware of noise pollution, tobacco toxicity and consanguinity. The Obstetrician and Pediatrician apart from ENT surgeon should be involved to prevent antenatal or neonatal deafness.

    We conducted this study is to investigate the clinical application value of Cyclin E, p27kip1 and Ki67 protein expression in colorectal cancer tissues for diagnosis, treatment, and prognosis of this disease. The positive expression of Cyclin E, p27kip1 and Ki-67 in tissues of 200 patients with colorectal cancer and 200 patients with benign colorectal tumor or inflammation were detected by immunohistochemistry PowerVision two-step method. RT-PCR was used to detect the expression level of the corresponding mRNA, as well as to analyze the association with TNM staging, pathology type, free progression survival and median survival. The sensitivity, specificity, and accuracy of diagnosis were analyzed by ROC. The positive expression rate and positive degree of Cyclin E and Ki-67 of observation group were higher than those of the control group, while positive expression rate and positive degree of p27kipl was lower than that of the control group; the differences were statistically significant (pcolorectal cancer tissues was upregulated and p27kipl protein expression was downregulated, which were closely related to the TNM and pathological differentiation degree. These values were also closely associated with free progression survival and median survival of prognosis. Therefore, the above indexes can be used as highly sensitive, specific and accurate markers for the diagnosis of colorectal cancer.

    Prune-belly syndrome (PBS) is a rare congenital syndrome characterized by deficient abdominal muscles, urinary tract malformation, and in males, cryptorchidism and has an estimated incidence of 1 in 35,000 to 1 in 50,000 live births. The syndrome might be due to severe bladder outlet obstruction or to abdominal muscle deficiency secondary to a migrational defect of the lateral mesoblast between weeks 6 and 7 of pregnancy. The current review of the medical record reports a special focus on epidemiology, genetic factors, early prenatal diagnosis clusters, treatment, and prognosis of PBS.

  11. Diagnosis, injury and prevention of internal radiation exposure

    2012-01-01

    Radiation exposure is classified into three categories: external exposure, surface contamination, and internal exposure (also called internal contamination). Internal exposure is an exposure by the ionizing radiation emitted from radioactive materials taken into a human body. Uptake of radioactive materials can go through inhalation, ingestion, or wound contamination. Not like external exposure, alpha ray or beta ray, which has a limited penetration, is also important in internal exposure. Diagnosis of internal exposure is based on measurement and dose assessment in addition to the history taking. Two methods, direct measurement and/or bioassay (indirect measurement), are used for the measurement. These measurements provide information of radioactive materials in the body at the time of the measurement. The exposure dose to the body needs to be calculated in a process of dose assessment, based on the results of these measurements and history of intake, either acute intake or chronic intake. Another method, measurement of environmental samples or food stuff, is also used for dose assessment. For internal exposure, radiation dose to the body is expressed as committed effective dose or committed equivalent dose, which are accumulation of dose over a defined period. Radioactive materials taken into body are transferred among many body components depending on the type of radionuclide or chemicals etc. Some radioactive materials concentrate in a specific organ. Symptoms and signs depend on the distribution of the radioactive materials in the body. Monitoring the concentration in air or foods is conducted in order to control human activities and foods and consequently reduce the amount of intake to human bodies as a preventive measure. Prevention of internal exposure is also conducted by protective gears such as full face masks. Iodine prophylaxis could be used against radioactive iodine intake. Stable iodine, mostly potassium iodide, could be taken into the thyroid and

    Objective: To investigate the value of determination of blood cardiac troponin T (cTnT), IL-8 and TNF-α contents for the diagnosis and prognosis assessment in patients with viral myocarditis (VMC). Methods: Plasma cTnT (with immuno-infiltration method) and serum IL - 8, TNF ( with ELISA) contents were measured in 86 patients with VMC at different stages ( 1 months, 6 months), and 30 controls. Results: The positive rates of blood cTnT, IL-8 and TNF-α in acute VMC patients were significantly higher than those in patients with history less than 6 months as well as with history more than 6 months and the controls group (P 0.05). The cure rate in patients with positive cTnT was significantly lower than that in patients with negative cTnT both at 1 months and 6 months (P<0.005). Conclusion: Blood cTnT, IL-8 and TNF-α are sensitive and specific predictors for diagnosis and prognosis assessment in patients with VMC. (authors)

    Full Text Available Anam Tariq,1 Kevin Westra,2 Arben Santo3 1Department of Internal Medicine, Pinnacle Health Internal Medicine, 2Department of Gastroenterology, Harrisburg Gastroenterology, Harrisburg, PA, 3Department of Pathology, Virginia College of Osteopathic Medicine-Virginia Tech, Blacksburg, VA, USA Background: While blood transfusions are commonly used for prophylaxis and treatment for acute chest syndromes and strokes in sickle cell patients, accumulation of excess iron resulting in secondary hemochromatosis remains a rare disease. Chelation is the mainstay for preventing and treating iron overload to deter potential end-organ damages; it is rare when therapy fails. Case report: A 52-year-old African American woman with chronic anemia secondary to sickle cell anemia and history of multiple blood transfusions presented with elevated serum ferritin (8000 ng/mL and bilirubin (16.8 mg/dL. She had no previous personal or family history of liver disease. A magnetic resonance cholangiopancreatography (MRCP and a liver biopsy confirmed the secondary hemochromatosis with marked fibrosis and 4+ iron deposits, but since she was therapeutically on deferasirox, her treatment regimen involved only closer monitoring. Her hemochromatosis led to readmission within a year for rapid progression of cardiac and hepatic failure. Conclusion: Since chronically transfused sickle cell patients are at a significantly higher risk of mortality due to the secondary hemochromatosis and end-stage organ damage, knowledge of prophylactic iron chelation is important. Minimizing unnecessary transfusions should be strongly emphasized to reduce the sequelae as iron burden remains a threat. The effectiveness of iron-chelating therapy is best monitored via periodic magnetic resonance imaging, liver transaminases, bilirubin, creatinine, ferritin, and cardiac function tests. Despite the prophylactic treatment and quarterly blood work, in this case the initial presentation did not correlate with

  15. Corneal allograft rejection: Risk factors, diagnosis, prevention, and treatment

    Full Text Available Recent advances in corneal graft technology, including donor tissue retrieval, storage and surgical techniques, have greatly improved the clinical outcome of corneal grafts. Despite these advances, immune mediated corneal graft rejection remains the single most important cause of corneal graft failure. Several host factors have been identified as conferring a "high risk" status to the host. These include: more than two quadrant vascularisation, with associated lymphatics, which augment the afferent and efferent arc of the immune response; herpes simplex keratitis; uveitis; silicone oil keratopathy; previous failed (rejected grafts; "hot eyes"; young recipient age; and multiple surgical procedures at the time of grafting. Large grafts, by virtue of being closer to the host limbus, with its complement of vessels and antigen-presenting Langerhans cells, also are more susceptible to rejection. The diagnosis of graft rejection is entirely clinical and in its early stages the clinical signs could be subtle. Graft rejection is largely mediated by the major histocompatibility antigens, minor antigens and perhaps blood group ABO antigens and some cornea-specific antigens. Just as rejection is mediated by active immune mediated events, the lack of rejection (tolerance is also sustained by active immune regulatory mechanisms. The anterior chamber associated immune deviation (ACAID and probably, conjunctiva associated lymphoid tissue (CALT induced mucosal tolerance, besides others, play an important role. Although graft rejection can lead to graft failure, most rejections can be readily controlled if appropriate management is commenced at the proper time. Topical steroids are the mainstay of graft rejection management. In the high-risk situations however, systemic steroids, and other immunosuppressive drugs such as cyclosporin and tacrolimus (FK506 are of proven benefit, both for treatment and prevention of rejection.

  16. Measurements of CFTR-mediated Cl- secretion in human rectal biopsies constitute a robust biomarker for Cystic Fibrosis diagnosis and prognosis.

    Marisa Sousa

    Full Text Available Cystic Fibrosis (CF is caused by ∼1,900 mutations in the CF transmembrane conductance regulator (CFTR gene encoding for a cAMP-regulated chloride (Cl(- channel expressed in several epithelia. Clinical features are dominated by respiratory symptoms, but there is variable organ involvement thus causing diagnostic dilemmas, especially for non-classic cases.To further establish measurement of CFTR function as a sensitive and robust biomarker for diagnosis and prognosis of CF, we herein assessed cholinergic and cAMP-CFTR-mediated Cl(- secretion in 524 freshly excised rectal biopsies from 118 individuals, including patients with confirmed CF clinical diagnosis (n=51, individuals with clinical CF suspicion (n=49 and age-matched non-CF controls (n=18. Conclusive measurements were obtained for 96% of cases. Patients with "Classic CF", presenting earlier onset of symptoms, pancreatic insufficiency, severe lung disease and low Shwachman-Kulczycki scores were found to lack CFTR-mediated Cl(- secretion (<5%. Individuals with milder CF disease presented residual CFTR-mediated Cl(- secretion (10-57% and non-CF controls show CFTR-mediated Cl(- secretion ≥ 30-35% and data evidenced good correlations with various clinical parameters. Finally, comparison of these values with those in "CF suspicion" individuals allowed to confirm CF in 16/49 individuals (33% and exclude it in 28/49 (57%. Statistical discriminant analyses showed that colonic measurements of CFTR-mediated Cl(- secretion are the best discriminator among Classic/Non-Classic CF and non-CF groups.Determination of CFTR-mediated Cl(- secretion in rectal biopsies is demonstrated here to be a sensitive, reproducible and robust predictive biomarker for the diagnosis and prognosis of CF. The method also has very high potential for (pre-clinical trials of CFTR-modulator therapies.

    Seventy-seven patients with large-focal myocardial infarction (MI), admitted to the intensive-care ward within 5 hours after the attack, were studied. Their serum myoglobin (MG) levels and MB CPK activity were monitored through 3 or 4 days of the disease. All MI patients showed a considerable rise in their serum MG within the first hours of infarction. In addition to its high diagnostic value, the measurement of serum MG can be helpful in assessing the severity and prognosis of the disease. The obtained evidence of a high linear dependence between cumulative MB CPK activity and the area under the MG curve, as well as a high correlation coefficient between the areas under serum MG and MB CPK curves, point in favor of using MG levels as a measure of the extent of the necrotic focus

    2018-02-13

    Neonatal herpes simplex virus infections are rare, but are associated with significant morbidity and mortality. Most newborns acquire herpes simplex virus infection in the peripartum period. For peripartum transmission to occur, women must be shedding the virus in their genital tracts symptomatically or asymptomatically around the time of delivery. There are evidence-based interventions in pregnancy to prevent the transmission to the newborn. Caesarean section should be performed in the presence of herpetic lesions, and antiviral prophylaxis in the last weeks of pregnancy is recommended to suppress genital tract herpes simplex virus at the time of delivery. The diagnosis and early treatment of neonatal herpes simplex virus infections require a high index of suspicion, especially in the absence of skin lesions. It is recommended to rule out herpes simplex virus infections in those newborns with mucocutaneous lesions, central nervous system involvement, or septic appearance. The prognosis of newborns with skin, eye, and/or mouth disease in the high-dose acyclovir era is very good. Antiviral treatment not only improves mortality rates in disseminated and central nervous system disease, but also improves the rates of long-term neurodevelopmental impairment in the cases of disseminated disease. Interestingly, a 6-month suppressive course of oral acyclovir following the acute infection has improved the neurodevelopmental prognosis in patients with CNS involvement. Copyright © 2018.

    We hypothesized that preceding zoonotic Salmonella or Campylobacter gastroenteritis aggravated the prognosis in cancer patients. Exposed patients comprised all of those diagnosed with first-time Salmonella/Campylobacter gastroenteritis from 1991 and with first-time cancer diagnosis thereafter (through 2003) in two Danish counties. These patients were matched for main cancer type, gender, age and calendar period to unexposed cancer patients, i.e. those without Salmonella/Campylobacter gastroenteritis. We compared cancer stage by age- and comorbidity-adjusted logistic regression analysis, survival by comorbidity-adjusted Cox's regression analysis and mortality dependent on the time period between Salmonella/Campylobacter gastroenteritis and cancer by spline regression curves. The study cohort comprised 272 Salmonella/Campylobacter-exposed cancer patients and 2681 unexposed cancer patients. Prevalence odds ratios [95% confidence intervals (CI)] in exposed as compared with unexposed patients were 0.96 (0.74-1.25) for localized tumours, 1.15 (0.87-1.54) for regional spread and 1.14 (0.84-1.55) for metastases. Adjusted mortality rate ratios (95% CI) were 0.93 (0.75-1.16) for 0-1 year, 1.08 (0.84-1.39) for 2-5 years and 1.02 (0.60-1.73) for the remaining period. Mortality estimates did not change in relation to the time period between gastroenteritis and cancer. Salmonella/Campylobacter gastroenteritis prior to cancer was associated with neither the cancer stage nor a poorer prognosis.

    IPSN in conjunction with EDF has been developing for the last years an approach for the diagnosis and prognosis of the Source Term during an accident on a PWR. Intended for the off-site emergency teams, this methodology is implemented with dedicated manual and computerized tools within the frame of the SESAME project. It is necessary to have access during the accident to various information dealing with the state of the plant. These information needs and the various means available to pick up data from the plant are described in this paper. Emphasis is given on the analysis of data that is needed to avoid any failure in the assessment of the state of the safety barriers and functions. This analysis deals with: the quality of the information depending on the environmental conditions and on the availability of the supply systems, the cross-check between measurements of same type, the cross-check between measurements of different types

    The aim of this study was to evaluate the supportive role of molecular and structural biomarkers (CSF protein levels, FDG PET and MRI) in the early differential diagnosis of dementia in a large sample of patients with neurodegenerative dementia, and in determining the risk of disease progression in subjects with mild cognitive impairment (MCI). We evaluated the supportive role of CSF Aβ{sub 42}, t-Tau, p-Tau levels, conventional brain MRI and visual assessment of FDG PET SPM t-maps in the early diagnosis of dementia and the evaluation of MCI progression. Diagnosis based on molecular biomarkers showed the best fit with the final diagnosis at a long follow-up. FDG PET SPM t-maps had the highest diagnostic accuracy in Alzheimer's disease and in the differential diagnosis of non-Alzheimer's disease dementias. The p-tau/Aβ{sub 42} ratio was the only CSF biomarker providing a significant classification rate for Alzheimer's disease. An Alzheimer's disease-positive metabolic pattern as shown by FDG PET SPM in MCI was the best predictor of conversion to Alzheimer's disease. In this clinical setting, FDG PET SPM t-maps and the p-tau/Aβ{sub 42} ratio improved clinical diagnostic accuracy, supporting the importance of these biomarkers in the emerging diagnostic criteria for Alzheimer's disease dementia. FDG PET using SPM t-maps had the highest predictive value by identifying hypometabolic patterns in different neurodegenerative dementias and normal brain metabolism in MCI, confirming its additional crucial exclusionary role.

    Full Text Available Long intergenic noncoding RNAs (lincRNAs are a relatively new class of non-coding RNAs that have the potential as cancer biomarkers. To seek a panel of lincRNAs as pan-cancer biomarkers, we have analyzed transcriptomes from over 3300 cancer samples with clinical information. Compared to mRNA, lincRNAs exhibit significantly higher tissue specificities that are then diminished in cancer tissues. Moreover, lincRNA clustering results accurately classify tumor subtypes. Using RNA-Seq data from thousands of paired tumor and adjacent normal samples in The Cancer Genome Atlas (TCGA, we identify six lincRNAs as potential pan-cancer diagnostic biomarkers (PCAN-1 to PCAN-6. These lincRNAs are robustly validated using cancer samples from four independent RNA-Seq data sets, and are verified by qPCR in both primary breast cancers and MCF-7 cell line. Interestingly, the expression levels of these six lincRNAs are also associated with prognosis in various cancers. We further experimentally explored the growth and migration dependence of breast and colon cancer cell lines on two of the identified lncRNAs. In summary, our study highlights the emerging role of lincRNAs as potentially powerful and biologically functional pan-cancer biomarkers and represents a significant leap forward in understanding the biological and clinical functions of lincRNAs in cancers.

    The increased expression of PDZ binding kinase/lymphokine-activated killer T-cell-originated protein kinase (PBK/TOPK) is associated with some human malignant tumors. In this study, we analyzed PBK/TOPK expression in hepatic primary tumor and explored its role in cholangiocarcinoma biology. Seventy-four cholangiocarcinomas, 33 hepatocellular carcinomas, and 10 normal liver tissues were prepared from paraffin-embedded specimens. PBK/TOPK protein was assessed by immunohistochemical staining, and the survival time was analyzed with the Kaplan-Meier method. The protein, mRNA of PBK/TOPK, and cell cycle of cholangiocarcinoma cell line after PBK/TOPK suppression with small interfere RNA were studied by Western blot, semiquantitative reverse transcriptase-polymerase chain reaction, and flow cytometry, respectively. PBK/TOPK was usually expressed in normal bile duct epithelial cells and much more frequently expressed in cholangiocarcinoma (68/74) but never expressed in hepatocytes and hepatocellular carcinomas (0/33). PBK/TOPK down-regulation was related to the poor prognosis of patients with cholangiocarcinoma (P = .013). Epidermal growth factor can enhance PBK/TOPK expression in cholangiocarcinoma QBC 939 cells, but suppression of PBK/TOPK in the cells did not affect their proliferation. PBK/TOPK protein could serve as a useful indicator for histopathologic differentiation between cholangiocarcinoma and hepatocellular carcinomas and the low expression of PBK/TOPK is predicative of poor survival in cholangiocarcinoma patients.

    Neurodegeneration and neurodegenerative disorders have been a global health issue affecting the aging population worldwide. Recent advances in stem cell biology have changed the current face of neurodegenerative disease modeling, diagnosis, and transplantation therapeutics. Stem cells also serve the purpose of a simple in-vitro tool for screening therapeutic drugs and chemicals. We present the application of stem cells and induced pluripotent stem cells (iPSCs) in the field of neurodegeneration and address the issues of diagnosis, modeling, and therapeutic transplantation strategies for the most prevalent neurodegenerative disorders. We have discussed the progress made in the last decade and have largely focused on the various applications of stem cells in the neurodegenerative research arena.

    The fucose-mannose ligand (FML)-ELISA assay showed a sensitivity of 100% and a specificity of 100% in diagnosis of canine visceral leishmaniasis (CVL) (kala-azar) in sera from naturally infected dogs from São Gonçalo do Amaranto, Rio Grande de Norte, Brazil. The overall prevalence of antibodies to Leishmania in the endemic area was 23% (79 of 343). Seroreactivity detected by a Leishmania chagasi immunofluorescent (IF) assay was much lower (2.9%) and similar to the percentage of dogs with kala-azar symptoms (2.6%). Twenty-one of 21 asymptomatic, FML-seropositive animals died of kala-azar in a period ranging from 0 to 6 months after diagnosis. The predictive value was 100% for the FML-ELISA, 43% for an L. mexicana ELISA, and 24% for the L. mexicana and L. chagasi IF assays, respectively. In experimentally infected dogs, all assays detected seropositivity between 90 and 120 days after infection. Since the current strategy for control of CVL is based on detection and destruction of infected dogs, the highly predictive, sensitive, and specific FML-ELISA represents a useful tool for field control of the disease.

    A prototype of a fiber-optic, multi-analyte, immunobiosensing system was developed to simultaneously quantify disease-representing biomarkers in blood plasma. This system was for simultaneous quantification of two different groups of multi-biomarkers related to cardiovascular diseases (CVD): anticoagulants (protein C, protein S, antithrombin III, and plasminogen) for deficiency diagnosis; and cardiac markers (B-type natriuretic peptide, cardiac troponin I, myoglobin, and C-reactive protein) for coronary heart disease diagnosis. As an initial effort towards the development of a disposable and easy-to-use sensing cartridge as a rapid diagnostic tool for CVD related diseases, a prototype of a flow control system was also developed to automatically perform simultaneous four-analyte quantification. Currently, the system is capable of quantifying the multiple anticoagulants in their clinically significant sensing ranges within 5 minutes, at an average signal-to-noise (S/N) ratio of 25. A simultaneous assay of the four cardiac markers can be performed within 10 min, at an average S/N ratio of 20. When this highly portable multi-analyte sensing system is completed and successfully tested for CVD patient's plasma, it can provide rapid (<10 min) and reliable diagnostic and prognostic information at a patient's bedside.

    To evaluate the early diagnostic value of matrix metalloproteinase-9 (MMP-9) level on admission for ST-segment elevation myocardial infarction (STEMI), explore the relationship between MMP-9 and global registry of acute coronary events (GRACE) scores and determine the values of MMP-9 in short-term prognosis of STEMI. A total of 55 STEMI patients admitted into our hospital between September 2011 and February 2012 were recruited. There were early STEMI (≤ 4h of onset, n = 22) and late STEMI (> 4 h after onset, n = 33). Fifty subjects of coronary artery without significant stenosis after angiography were enrolled into a control group. The plasma levels of MMP-9 in venous blood were detected with enzyme-linked immunosorbent assay (ELISA). And the GRACE risk score was used for risk assessment. The incidence of new or recurrent myocardial infarction, target vessel revascularization, cardiac death, heart failure (MACE) was recorded during a follow-up period of 6 months. The MMP-9 levels were significantly higher in patients with STEMI (P 0.05). The level of MMP-9 was positively correlated with the GRACE risk score. MACE occurred in 8 [14.5% (8/55)] patients during hospitalization and 17 [30.9% (17/55)] patients during follow-up. Receiver operating characteristic (ROC) curve analysis showed area under the curve (AUC) of on admission GRACE risk score and MMP-9 levels were 0.848 (95%CI 0.706 - 0.991, P = 0.002) and 0.766 (95%CI 0.575 - 0.957, P = 0.017) respectively. ROC curve analysis showed AUC of hospital discharge GRACE risk score and MMP-9 levels were 0.737 (95%CI 0.601 - 0.873, P = 0.005) and 0.711 (95%CI 0.565 - 0.856, P = 0.013) respectively. No statistical differences existed between GRACE risk score and MMP-9 levels for predicting the short-term risk of MACE (P > 0.05). The plasma level of MMP-9 has a higher diagnostic value for early STEMI. Positively correlated with the GRACE risk score, it is a predicator of short-term risk of MACE.

    2011-06-01

    Full Text Available The guidelines for the osteoporosis management were first drafted by a working group and then critically evaluated by the board of SIOMMMS. The most relevant points are: Definition: Osteoporosis is defined as a quantitative and qualitative deterioration of bone tissue leading to increased risk of fracture. Postmenopausal and senile osteoporosis are defined as primitive. Diagnosis: The cornerstone for the diagnosis of osteoporosis is the measurement of bone mineral density (BMD by DXA (dual-energy X-ray absortiometry at the femoral neck with T-score values -2.5 is usually not justified. Pharmacological intervention: The use of drugs registered for the treatment of osteoporosis are recommended when the benefits overcome the risk. This is the case only when the risk of fracture is rather high. FRAX™ is recognized as a useful tool for easily estimate the long-term fracture risk. SIOMMMS with these guidelines is committed to validate and further develop this diagnostic tool.

    Full Text Available The aim of the study – determining of changes in peripheral blood (PB in patients with secondary erythrocytosis (SE and polycythemia vera (PV, detection of discriminatory parameters levels of PB indicators and analyzing of their operating characteristics for differentiation of erythrocytosis and predicting of thrombotic events in patients with PV. Materials and methods. The material for the study was the results of clinical trials of 210 patients with erythrocytosis who underwent differential diagnosis between PV and SE. Results and discussion. The optimal threshold for differential diagnosis of red blood cells content between PV and SE is >6.08•1012/ L, the diagnostic value of the marker equals to the level of a good diagnostic marker (AUC=0.82; 95% CI=0.77-0.87, p 57.5% with its capacity – 0.72 (0.66-0.78, p 8.9•109/L, and the boundary of marker is consistent with a good level of efficiency (AUC=0.79, 95% CI=0.72-0.84, p287•109 /L" to differentiate erythrocytosis is 0.90 (0.86-0.94, p 55%" and "WBC >12.3•109 /L", according to the AUC (AUC=0.65; 95% CI=0.52-0.79, p=0.021 and AUC=0.66; 95% CI=0.55-0.77, p=0.003, respectively, corresponds to the average power level. Conclusion. Hemoglobin has not confirmed its value for the differential diagnosis between PV and SE. Using other parameters of PB with the aim of differentiating PV and SE is rational, but their discriminatory power levels greatly depend on the group erythrocytosis. In our cohort were obtained the following most appropriate criteria for inclusion of patients in the group of patients with PV: "WBC >8.9•109/L", "red blood cells >6.08•1012/L" and "hematocrit >57.5%". The most significant marker of general clinical blood test to differentiate between PV and SE is "platelets >287•109/L". Hematocrit over 55% and WBC over 12.3•109/L are valuable prognostic markers of thrombosis in PV patients, but their use is appropriate only in a cohort of patients with PV without

    A retrospective cohort study of 2321 patients consecutively admitted to one center and diagnosed with acute symptoms of metastatic spinal cord compression (MSCC). To assess the possible change in 1-year survival for patients with MSCC from year 2005 through 2010 with respect to the primary cancer diagnosis. An increasing number of patients are offered surgical treatment for MSCC. Among the reasons for this development are high evidence clinical studies, improved surgical techniques, and an increasing number of patients being treated for an oncological condition. Preoperative scoring systems are routinely used in the evaluation of these patients, and the primary oncological diagnosis is an important variable in all these systems. To our knowledge, no studies in a large group of patients have assessed the change in survival in these patients. This is of relevance because such changes in survival could have implications on the scoring systems used in the preoperative evaluation. All patients referred to the university hospital, Rigshospitalet, suspected of acute symptoms caused by spinal metastases and diagnosed with MSCC from January 1, 2005, to December 31, 2010, were included in a retrospective cohort, n = 2321. For all patients primary tumor, treatment, and 1-year survival was registered. The overall 1-year survival did not change significantly from 2005 to 2010, but there was a significant increase in 1-year survival for the subgroups of patients with lung cancer hazard ratio = 0.93 (P = 0.008, 95% CI: 0.83-0.98) and renal cancer hazard ratio = 0.77 (P = 0.004, 95% CI: 0.56-0.92). Patients with MSCC from pulmonary and renal cancers experienced improved survival in the study period. No improvement was seen for patients with other oncological diagnoses. This corresponds to reports from oncological studies and could affect preoperative scoring systems.

    To investigate the significance of the related indexes of three-dimensional color power angiography (3D-CPA) combined with SonoVue angiography in the diagnosis and prognosis evaluation of intrauterine adhesion (IUA). The accuracy, sensitivity, and specificity were evaluated between 3D-TVS and hysteroscopy. Endometrial thickness, volume (V), mean gray value (MG), vascularization index (VI), flow index (FI), vascularization flow index (VFI), and other related indexes before and after the angiography were compared. According to the hysteroscopy findings, the patients were divided into three groups: mild, medium, and severe. The endometrial thickness at 3 months postoperatively and the pregnancy rates at 1 year postoperatively were compared. Compared with the hysteroscopy, sensitivity: 0.970 (0.021), specificity: 0.667 (0.086), (the values inside the bracket were the standard error), positive likelihood ratio: 2.909, negative likelihood ratio: 0.045. There was a significant difference in endometrial thickness and V between the three groups (P0.05). During intravenous injection of SonoVue, the blood flow of each group increased (P<0.001), and the VI, FI, and VFI of each group were significantly different (P<0.05). Compared with the preoperative values, the endometrial thickness, V, MG, VI, FI, and VFI significantly changed at 3 months postoperatively (P<0.05). The mild group and high VI group had a higher pregnancy success rate at one year postoperatively. 3D-CPA can indirectly diagnose IUA, and may play an important role in prognosis assessment.

    2013-04-01

    Full Text Available Background In Côte d’Ivoire, acute leukemias account for 12.5% of hematological malignancies. Acute leukemias are due to an anomaly of the stem cell characterized among other things by the expression of CD34+ CD38- surface markers. This CD34+ CD38- phenotype as well as other factors such as tumor syndrome, high leukocytosis and blasts are considered as important factors of poor prognosis. We therefore proposed to investigate the prognostic value of the expression of CD34+ CD38- markers in acute leukemias in Abidjan. Methods We selected 23 patients aged 33 years on whom we performed Complete Blood Count, bone marrow aspiration and immunophenotyping. To search for myeloperoxydase, smears of blood or bone marrow were stained with benzidine and revealed by the use of Hydrogen peroxide. Acute leukemias were then identified and distributed using the score proposed by the European Group for the Immunological characterization of Leukemias. The definitive diagnosis was made by combining morphological characters that serve as the basis for the French-American-British classification as well as cytochemical and immunophenotypic characters. Results According to the cytological and immunophenotypic classifications, the acute lymphoid leukemia 2 and B IV predominated. 52.2% (12/33 of patients were CD34+ CD38-. This phenotype was found in almost all cytological immunophenotypic types. The medullary invasion by blasts (reflection of the tumor mass of the total sample of CD34+ , CD34+ CD38- patients and those not expressing CD34+ was respectively 79.4%, 81.25%, 83.3% and 74.8%. Conclusion There was therefore no correlation between medullary blasts and the expression of CD34+ CD38-. To the factors we selected it would have been necessary to associate the study ofcytogenetic and molecular anomalies to better understand the role of CD34+ CD38- phenotype, concerning prognosis.

    Full Text Available Abstract Background: International studies have reported the value of the clinical profile and laboratory findings in the diagnosis of constrictive pericarditis. However, Brazilian population data are scarce. Objective: To assess the clinical characteristics, sensitivity of imaging tests and factors related to the death of patients with constrictive pericarditis undergoing pericardiectomy. Methods: Patients with constrictive pericarditis surgically confirmed were retrospectively assessed regarding their clinical and laboratory variables. Two methods were used: transthoracic echocardiography and cardiac magnetic resonance imaging. Mortality predictors were determined by use of univariate analysis with Cox proportional hazards model and hazard ratio. All tests were two-tailed, and an alpha error ≤ 5% was considered statically significant. Results: We studied 84 patients (mean age, 44 ± 17.9 years; 67% male. Signs and symptoms of predominantly right heart failure were present with jugular venous distention, edema and ascites in 89%, 89% and 62% of the cases, respectively. Idiopathic etiology was present in 69.1%, followed by tuberculosis (21%. Despite the advanced heart failure degree, low BNP levels (median, 157 pg/mL were found. The diagnostic sensitivities for constriction of echocardiography and magnetic resonance imaging were 53.6% and 95.9%, respectively. There were 9 deaths (10.7%, and the risk factors were: anemia, BNP and C reactive protein levels, pulmonary hypertension >55 mm Hg, and atrial fibrillation. Conclusions: Magnetic resonance imaging had better diagnostic sensitivity. Clinical, laboratory and imaging markers were associated with death.

    Full Text Available Necrotizing enterocolitis (NEC is a major source of neonatal morbidity and mortality. Since there is no specific diagnostic test or risk of progression model available for NEC, the diagnosis and outcome prediction of NEC is made on clinical grounds. The objective in this study was to develop and validate new NEC scoring systems for automated staging and prognostic forecasting.A six-center consortium of university based pediatric teaching hospitals prospectively collected data on infants under suspicion of having NEC over a 7-year period. A database comprised of 520 infants was utilized to develop the NEC diagnostic and prognostic models by dividing the entire dataset into training and testing cohorts of demographically matched subjects. Developed on the training cohort and validated on the blind testing cohort, our multivariate analyses led to NEC scoring metrics integrating clinical data.Machine learning using clinical and laboratory results at the time of clinical presentation led to two nec models: (1 an automated diagnostic classification scheme; (2 a dynamic prognostic method for risk-stratifying patients into low, intermediate and high NEC scores to determine the risk for disease progression. We submit that dynamic risk stratification of infants with NEC will assist clinicians in determining the need for additional diagnostic testing and guide potential therapies in a dynamic manner.http://translationalmedicine.stanford.edu/cgi-bin/NEC/index.pl and smartphone application upon request.

    2017-06-01

    The regular update of the guidelines on fibromyalgia syndrome, AWMF number 145/004, was scheduled for April 2017. The guidelines were developed by 13 scientific societies and 2 patient self-help organizations coordinated by the German Pain Society. Working groups (n =8) with a total of 42 members were formed balanced with respect to gender, medical expertise, position in the medical or scientific hierarchy and potential conflicts of interest. A systematic search of the literature from December 2010 to May 2016 was performed in the Cochrane library, MEDLINE, PsycINFO and Scopus databases. Levels of evidence were assigned according to the classification system of the Oxford Centre for Evidence-Based Medicine version 2009. The strength of recommendations was achieved by multiple step formalized procedures to reach a consensus. The guidelines were reviewed and approved by the board of directors of the societies engaged in the development of the guidelines. The clinical diagnosis of fibromyalgia syndrome can be established by the American College of Rheumatology (ACR) 1990 classification criteria (with examination of tender points) or without the examination of tender points by the modified preliminary diagnostic ACR 2010 or 2011 criteria.

  5. Beyond HbA1c and glucose: the role of nontraditional glycemic markers in diabetes diagnosis, prognosis, and management

    Parrinello, Christina M.; Selvin, Elizabeth

    2014-01-01

    Fasting glucose and hemoglobin A1c (HbA1c) are the standard measures for diagnosis and monitoring of diabetes. There has been recent interest in nontraditional markers of hyperglycemia, including fructosamine, glycated albumin and 1,5-anhydroglucitol (1,5-AG), as alternatives or adjuncts to standard measures. There is a growing literature linking these nontraditional markers with microvascular and macrovascular complications. Fructosamine and glycated albumin have also been shown to improve identification of persons with diabetes. However, long-term prospective studies with clinical outcomes are lacking. Some modern laboratory assays for fructosamine, glycated albumin and 1,5-AG have excellent performance. Expanded use of these tests has the potential to improve diabetes care as these measures may overcome limitations of HbA1c in certain patients, complement traditional measures by providing additional information on shorter-term glycemic control, and improve risk stratification for diabetes and its complications. Nonetheless, studies are needed to demonstrate if their routine use will benefit patients and improve outcomes. PMID:25249070

    Gingivitis and chronic periodontitis are highly prevalent chronic inflammatory diseases. Gingivitis affects the majority of people, and advanced periodontitis is estimated to affect 5-15% of adults. The detection and diagnosis of these common diseases is a fundamentally important component of oral health care. All patients should undergo periodontal assessment as part of routine oral examination. Periodontal screening using methods such as the Basic Periodontal Examination/Community Periodontal Index or Periodontal Screening Record should be performed for all new patients, and also on a regular basis as part of ongoing oral health care. If periodontitis is identified, full periodontal assessment is required, involving recording of full mouth probing and bleeding data, together with assessment of other relevant parameters such as plaque levels, furcation involvement, recession and tooth mobility. Radiographic assessment of alveolar bone levels is driven by the clinical situation, and is required to assess bone destruction in patients with periodontitis. Risk assessment (such as assessing diabetes status and smoking) and risk management (such as promoting smoking cessation) should form a central component of periodontal therapy. This article provides guidance to the oral health care team regarding methods and frequencies of appropriate clinical and radiographic examinations to assess periodontal status, to enable appropriate detection and diagnosis of periodontal conditions.

    2003-06-01

    Many morphologic, physical, and iatrogenic factors, such as deep grooves, pronounced intraoral temperature fluctuation, poor cavity preparation design, and wrong selection of restorative materials, may predispose posterior teeth to an incomplete fracture. The resulting cracked tooth syndrome is frequently associated with bizarre symptoms that may complicate diagnosis and can persist for many years. Epidemiologic data reveal that splits or fractures are the third most common cause of tooth loss in industrialized countries, primarily affecting maxillary molars and premolars and mandibular molars. This finding indicates that the cracked tooth syndrome is of high clinical importance. Thus, at-risk teeth should be reinforced early, for instance by castings with cusp coverage or by internal splinting with adhesive ceramic restorations.

    Full Text Available Emma R Schachner, Mandi J Lopez Department of Veterinary Clinical Sciences, School of Veterinary Medicine, Louisiana State University, Baton Rouge, LA, USA Abstract: Canine hip dysplasia (CHD is a polygenic and multifactorial developmental disorder characterized by coxofemoral (hip joint laxity, degeneration, and osteoarthritis (OA. Current diagnostic techniques are largely subjective measures of joint conformation performed at different stages of development. Recently, measures on three-dimensional images generated from computed tomography scans predicted the development of OA associated with CHD. Continued refinement of similar imaging methods may improve diagnostic imaging techniques to identify dogs predisposed to degenerative hip joint changes. By current consensus, joint changes consistent with CHD are influenced by genetic predisposition as well as environmental and biomechanical factors; however, despite decades of work, the relative contributions of each to the development and extent of CHD signs remain elusive. Similarly, despite considerable effort to decipher the genetic underpinnings of CHD for selective breeding programs, relevant genetic loci remain equivocal. As such, prevention of CHD within domestic canine populations is marginally successful. Conservative management is often employed to manage signs of CHD, with lifelong maintenance of body mass as one of the most promising methods. Surgical intervention is often employed to prevent joint changes or restore joint function, but there are no gold standards for either goal. To date, all CHD phenotypes are considered as a single entity in spite of recognized differences in expression and response to environmental conditions and treatment. Identification of distinct CHD phenotypes and targeting evidence-based conservative and invasive treatments for each may significantly advance prevention and management of a prevalent, debilitating condition in canine companions.

    Hostility towards relationships is one prominent characteristic symptom for disorders of sexual preference (ICD-10) and paraphilias (DSM-IV). Paraphilic symptoms sometimes progress to obsessive or addictive- like forms leading to a loss of self-control but can occur also as single incidents or as episodic events. Besides constitutional aspects, problems in the development of close relationships to primary caregivers (attachment) play an important role in the development of these disorders. Actual relationship- and self-confidence problems often trigger the severity of disturbance, especially in the episodic forms of paraphilia. For patients who are in conflict with the law, cognitive-behavioral therapeutic approaches with the aim to minimize self-deception regarding the effects of the paraphilic behavior have become more and more relevant. Regarding the medical treatment, anti-hormonal therapy plays an important role, but also treatment with serotonergic agents and naltrexone are used. Only little can be advised in terms of prevention; general psycho-hygiene (regarding the parent-child relationship) is recommended. Beside these general measures, institutions which offer special treatment for people in danger to become delinquents may be able to prevent serious harm for possible victims of abuse.

    Full Text Available  Colorectal cancer is the most common cancer of the gastrointestinal tract. It is considered as a biological model of a certain type of cancerogenesis process in which progression from an early to late stage adenoma and cancer is accompanied by distinct genetic alterations.Clinical and pathological parameters commonly used in clinical practice are often insufficient to determine groups of patients suitable for personalized treatment. Moreover, reliable molecular markers with high prognostic value have not yet been determined. Molecular studies using DNA-based microarrays have identified numerous genes involved in cell proliferation and differentiation during the process of cancerogenesis. Assessment of the genetic profile of colorectal cancer using the microarray technique might be a useful tool in determining the groups of patients with different clinical outcomes who would benefit from additional personalized treatment.The main objective of this study was to present the current state of knowledge on the practical application of gene profiling techniques using microarrays for determining diagnosis, prognosis and response to treatment in colorectal cancer.

    Diagnosing impingement syndrome without rotator cuff tear usually depends on the physical examination and roentgenography, and obtaining objective evidence for this condition is at best difficult. The purpose of this study was to ascertain whether quantitatively assessing this condition with using single photon emission computerized tomography (SPECT) can diagnose impingement syndrome and predict the postoperative results. Before executing arthroscopic or open treatment, SPECT was performed on 73 patients and 24 volunteers and these people were followed up for 2 years. Any increased uptake on SPECT was investigated by using the axial view, which demonstrated the greatest uptake for the acromion, distal clavicle, greater tuberosity, lesser tuberosity and the coracoid process of the operated and non-operated sides. The patients who were diagnosed as having impingement syndrome with or without rotator cuff tear showed increased uptake on the operative side compared to the non-operated side in the assessed locations. The greater tuberosity of the humerus could be used for quantitative measurement as a postoperative prognostic factor. The bone SPECT method is useful for making the diagnosis of patients with impingement syndrome, and the results of quantitative assessment at the greater tuberosity can be used for evaluating the prognosis following the operation.

    Kashin-Beck Disease (KBD) is a chronic deforming osteoarthritis starting in early childhood and affecting the cartilage metabolism and endochondral ossification. Selenium (Se) deficiency has been postulated as the major environmental etiological factor for KBD by many studies. Other minerals such as the Manganese (Mn) and calcium (Ca) which don't have uniform distribution in environment are also important elements involved in bone and cartilage formation but their regulation in KBD has been rarely reported. The study was done to investigate the role of Mn and Ca in addition to Se in KBD. In this study, the Se, Mn and Calevels were investigated in children from different groups (KBD group, Healthy group from KBD endemic areas (inner control group), Healthy group (outer control group) from Non KBD areas and KBD group with selenium supplementation). The contents of Mn, S and Ca in serum and hair were analyzed by inductively coupled plasma mass spectrometry. The increased Mn levels of. serum and hair in KBD children were observed compared with normal groups. The Mn and Ca have similar trends in different groups but Se and Mn displayed reversed trends. The Mn and Ca contributed to KBD pathogenesis combined with se in regulation of growth and development. The relative ratio of Mn to Se can be a potential clinical index in early diagnosis, monitoring and prognosis of KBD in children.

    In the Netherlands last year two important policy changes were introduced to prevent haemolytic disease of the newborn: antenatal administration of anti RhD immunoglobulin and screening for antibodies against irregular erythrocyte antigens in all pregnant women. As the predictive value of such antibodies for the detection of hemolytic disease of the newborn is limited, it is uncertain if this measure is really cost-effective. Because blood transfusion is the most important probable cause of the immunization, and because of the clinical severity of anti-K antibodies, it is advised to give exclusively K negative blood to girls and women under the age of 45 years. In addition there is a need for a uniform protocol to deal with women who have been exposed to immunization.

    Full Text Available Despite widespread vaccination, pertussis remains an important cause of infant morbidity and mortality. About 16 million people are ill with this disease and approximately 195 thousand children die worldwide every year. However, only 5—10% of all pertussis cases are diagnosed and notified. In spite of wide immunization coverage, there is really a pertussis epidemic in many countries of the world now; moreover, vaccinated children constitute a high proportion of disease cases. Adolescents and adults are a major reservoir for cyclic outbreaks of pertussis; however, they are rarely diagnosed with the disease. The review gives scientists' opinion on the causes of this phenomenon and proposed measures to reduce morbidity in different age groups. The severe and complicated forms of pertussis and fatal outcomes occur in babies during the first months of life and therefore current vaccination strategies should be aimed at preventing the infection just in this age group of children.

    2010-11-01

    The number of people suffering from surgery and obesity in the western world is constantly growing. In 1997 the World Health Organization (WHO) defined obesity as a plague and one of greatest public health hazards of our time. The National Institution of Health (NIH) declared that surgery is the only long-term solution for obesity. Today there are four different types of bariatric surgery. Each variation has different implications on the nutritional status of bariatric surgery patients. Bariatric surgery candidates are at risk of developing vitamin and mineral nutritional deficiencies in the post-operative stage, due to vomiting, decrease in food intake, food intolerance, diminution of gastric secretions and bypass of absorption area. It is easier and more efficient to treat nutritional deficiencies in the preoperative stage. Therefore, preoperative detection and correction are crucial. Blood tests before surgery to detect and treat nutritional deficiencies are crucial. In the postoperative period, blood tests should be conducted every 3 months in the first year after operation, every six months in the second year and annually thereafter. Multivitamin is recommended to prevent nutritional deficiencies in all bariatric surgery patients. Furthermore, iron, calcium, Vitamin D and B12 are additionally recommended for Roux-en-Y Gastric Bypass patients. Patients with Biliopancreatic diversion and Duodenal Switch should also take fat soluble vitamins.

    Full Text Available Intestinal infections caused by rod-shaped bacteria of the [i]Enterobacteriaceae[/i] genus are one of the major health hazards in countries where sanitation standards are low. [i]Strains[/i] of [i]Shigella,[/i] [i]Salmonella, Escherichia[/i] and [i]Yersinia [/i]are responsible for diarrhea, severe bacillary dysentery, typhoid, other intestinal diseases, as well as genitourinary tract and blood infections. According to the WHO there are 4.5 billion cases every year, of which 1.9 million end in death. This makes intestinal infections third in terms of human disease mortality. In this work we discuss methods of pathogen identification, the mechanism of host-pathogen interaction, and the nature of the ¬host’s immunological response. Due to rising drug resistance we discuss the importance of better pathogen detection, vaccine design and the use of vaccines as a preventive measure against intestinal infections. Special attention is paid to OMP38, a protein isolated from [i]S. flexneri[/i] 3a outer membrane. Since it is known that this protein has good immunogenic properties, it can be used as an antigen or carrier for conjugate vaccines.

    The epithelial ovarian cancer (EOC) has been underdiagnosed because it does not have a specific clinical presentation, and the signs and symptoms are similar to the irritable bowel syndrome and pelvic inflammatory disease. EOC is less common than breast and cervical cancer, but it is more lethal. On the whole, EOC has an early dissemination to peritoneal cavity, which delays a timely diagnosis and increases the rate of advanced diagnosed disease. The diagnosis usually surprises the women and the primary care physician. Therefore, it is necessary to count on prevention and early diagnosis programs. EOC has 80% response to surgical treatment, but nearly 70% of the patients may relapse in five years. The objectives of this document are presenting a summary of the EOC epidemiology and comment about advancements in prevention, diagnosis, and treatment of this cancer. That will raise awareness about the importance of this disease.

    To evaluate the application value of serum CA19-9, CEA, CA125 and CA242 in diagnosis and prognosis of pancreatic cancer cases treated with concurrent chemotherapy. 52 patients with pancreatic cancer, 40 with benign pancreatic diseases and 40 healthy people were selected. The electrochemiluminescence immunoassay method was used for detecting levels of CA19-9, CEA and CA125, and a CanAg CA242 enzyme linked immunoassay kit for assessing the level of CA242. The Kaplan-Meier method was used for analyzing the prognostic factors of patients with pancreatic cancer. The Cox proportional hazard model was applied for analyzing the hazard ratio (HR) and 95% confidential interval (CI) for survival time of patients with pancreatic cancer. The levels of serum CA19-9, CEA, CA125 and CA242 in patients with pancreatic cancer were significantly higher than those in patients with benign pancreatic diseases and healthy people (PCEA. The specificity of CA242 is the highest, followed by CA125, CEA and CA19-9. The sensitivity and specificity of joint detection of serum CA19-9, CEA, CA125and CA242 were 90.4% and 93.8%, obviously higher than single detection of those markers in diagnosis of pancreatic cancer. The median survival time of 52 patients with pancreatic cancer was 10 months (95% CI7.389~12.611).. Patients with the increasing level of serum CA19-9, CEA, CA125, CA242 had shorter survival times (P=0.047. 0.043, 0.0041, 0.029). COX regression analysis showed that CA19-9 was an independent prognostic factor for patients with pancreatic cancer (P=0.001, 95%CI 2.591~38.243). The detection of serum tumor markers (CA19.9, CEA, CA125 and CA242) is conducive to the early diagnosis of pancreatic cancer and joint detection of tumor markers helps improve the diagnostic efficiency. Moreover, CA19-9 is an independent prognostic factor for patients with pancreatic cancer.

    Full Text Available Preimplantation Genetic Diagnosis (PGD is currently an alternative for couples with high risk of pregnancies with genetic anomalies; it offers the possibility of avoiding the need to terminate affected pregnancies, since it allows the selection of unaffected embryos for transfer. PGD for inherited disorders has become extremely accurate (99.5%, and may currently be performed for any single gene disorders in which mutation is identified. PGD has been performed for more than 100 different conditions resulting in the birth of at least 1000 healthy children free of genetic disorder. PGD is presently also used together with preimplantation HLA typing for treatment of affected sibling with genetic and acquired disorders requiring HLA matched stem cell transplantation. This is not only to allow couples to have an unaffected child but also to select a potential donor progeny for stem cell transplantation. In Turkey, thalassemia is the most commonly seen genetic disorder the rate of thalassemia carriers is about 3 - 4% in Turkey. The majority of our PGD cases are thalassemia carriers. They do not only require thalassemia mutation analysis but also HLA typing for their affected child. In this study PGD results of 236 Turkish couples with or without HLA typing will be presented and discussed. A full diagnosis was achieved in 91.0% of the biopsied samples. In Group I, 17.8% of the analyzed embryos were found to be HLA compatible. HLA compatible and disease free embryos were 12.9% of all diagnosed embryos. In group II, 17.2% of embryos were found to be HLA matched and 71.4% HLA non-matched. The majority of our HLA typing combined with PGD cases were β-Thalassemia carriers (87.9%. The mutations analyzed have high heterogeneity, the most frequent mutation was IVS-I-110 G-A and comprised 46.2% of all mutations. To date, 70 healthy and HLA compatible children have been born. Twenty-five sick children have already been cured with cord blood cell and/or bone

    Full Text Available Etiology and classification: Causal factors related with cognitive disability are multiples and can be classified as follows: Genetic, acquired (congenital and developmental, environmental and sociocultural. Likewise, in relation to the classification, cognitive disability has as a common denominator a subnormal intellectual functioning level; nevertheless, the extent to which an individual is unable to face the demands established by society for the individual’s age group has brought about four degrees of severity: Mild, moderate, severe and profound. Diagnostic: The clinical history must put an emphasis on healthcare during the prenatal, perinatal and postnatal period and include the results of all previous studies, including a genealogical tree for at least three generations and an intentional search for family antecedents of mental delay, psychiatric illnesses and congenital abnormalities. The physical exam should focus on secondary abnormalities and congenital malformations, somatometric measurements and neurological and behavioral phenotype evaluations. If it is not feasible to establish a clinical diagnosis, it is necessary to conduct high-resolution cytogenetic studies in addition to metabolic clinical evaluations. In the next step, if no abnormal data are identified, submicroscopic chromosomal disorders are evaluated. Prognosis: Intellectual disability is not curable; and yet, the prognostic in general terms is good when using the emotional wellbeing of the individual as a parameter. Conclusions: Intellectual disability should be treated in a comprehensive manner. Nevertheless, currently, the fundamental task and perhaps the only one that applies is the detection of the limitation and abilities as a function of subjects’ age and expectations for the future, with the only goal being to provide the support necessary for each one of the dimensions or areas in which the person’s life is expressed and exposed.Etiología y clasificaci

    Full Text Available Background and objective Increased macrophage inhibitory cytokine-1 (MIC-1, member of transforming growth factor-β (TGF-β superfamily, was found in patients serum with epithelial tumors. Therefore, our aim was to delineate the diagnostic and prognostic value of serum MIC-1 in patients with stage I-II non-small cell lung cancer (NSCLC. Methods A total of 152 consecutive patients with stage I–II NSCLC were prospectively enrolled and underwent follow up after total resection of tumor. Serum MIC-1 level was detected in lung cancer patients by ELISA, 48 benign pulmonary disease patients and 105 healthy controls, and was correlated with clinical features and prognosis of patients. Results The level of MIC-1 of NSCLC patients was significantly higher than that of controls (P<0.001 and benign pulmonary disease patients (P<0.001. A threshold of 1,000 pg/mL could be used to diagnose early-stage NSCLC with 70.4% sensitivity and 99.0% specificity. The level of MIC-1 was associated with elder age (P=0.001, female (P=0.03 and T2 (P=0.022. A threshold of 1,465 pg/mL could identify patients with early poor outcome with 72.2% sensitivity and 66.1% specificity. The overall 3-year survival rate in patients with high level of MIC-1 (≥1,465 pg/mL was significantly lower than that of patients with low MIC-1 level (77.6% vs 94.8%. Multivariable Cox regression revealed that a high level of MIC-1 was an independent risk factor for compromised overall survival (HR=3.37, 95%CI: 1.09-10.42, P=0.035. Conclusion High level of serum MIC-1 could be served as a potential biomarker for diagnosis and poorer outcome in patients with early-stage NSCLC.

    Overtraining syndrome is a condition of maladapted physiology in the setting of excessive exercise without adequate rest. The exact etiology and pathogenesis are unknown and being investigated. Symptoms are multisystem in nature and often representative of underlying hormonal, immunologic, neurologic, and psychologic disturbances. Unfortunately, systematic review of the literature does not clearly direct diagnosis, management, or prevention. However, given the severity of symptoms and impairment to quality of life, prevention of overtraining syndrome should be considered by all who interact with endurance athletes. This article will provide suggestions for management of at-risk athletes despite absence of validated diagnostic tests and preventative measures.

    Recent evidences indicate that circulating microRNAs (miRNAs) exhibit aberrant expression in the plasma of patients suffering from cancer compared to normal individuals, suggesting that it may be a useful noninvasion diagnostic method. MiR-21 plays crucial roles in carcinogenesis and can be served as a biomarker for the detection of various cancers. Therefore, the aim of this meta-analysis is to assess the potential role of miR-21 for digestive system cancer. By searching the PubMed, Embase, and Web of Science for publications concerning the diagnostic value of miR-21 for digestive system cancer, total of 23 publications were included in this meta-analysis. Receiver operating characteristic curves (ROC) were used to check the overall test performance. For prognostic meta-analysis, pooled hazard ratios (HRs) of circulating miR-21 for survival were calculated. Totally 23 eligible publications were included in this meta-analysis (15 articles for diagnosis and 8 articles for prognosis). For diagnostic meta-analysis, the summary estimates revealed that the pooled sensitivity and specificity were 0.76 (95% CI = 0.70-0.82) and 0.84 (95% CI = 0.78-0.89). Besides, the area under the summary ROC curve (AUC) is 0.87. For prognostic meta-analysis, the pooled HR of higher miR-21 expression in circulation was 1.94 (95% CI = 0.99-3.82, P = 0.055), which indicated higher miR-21 expression could be likely to predict poorer survival in digestive system cancer. The subgroup analysis implied the higher expression of miR-21 was correlated with worse overall survival in the Asian population in digestive system cancer (HR = 2.41, 95% CI = 1.21-4.77, P = 0.012). The current evidence suggests circulating miR-21 may be suitable to be a diagnostic and prognostic biomarker for digestive system cancer in the Asians.

A total of 500 adults aged≥18years who presented to a primary care physiotherapist. Participants were recruited from 10 private practices within the Sydney metropolitan area. Participants completed a survey assessing how important five aspects of physiotherapy care were in their initial decision to present to a primary care physiotherapist. These aspects were: diagnosis; information and education; treatment for pain relief; treatment to improve function; and prevention. The survey also collected characteristics of the patients and information about their presentation to the physiotherapist, to assess whether these factors were associated with the aspects of physiotherapy care that they considered most important. A total of 500 surveys were completed, with a response rate of 94%. All five aspects of physiotherapy care were considered either 'quite important' or 'extremely important' by most participants (diagnosis 65%; information and education 68%; pain relief 89%; improved function 93%; prevention 90%). Patient factors were associated with the participants' ratings of importance. Female participants and those with spinal pain more commonly rated pain relief as highly important. Participants with lower educational levels were more likely to rate diagnosis and information and education as important. This study demonstrated that most patients presenting to primary care physiotherapists value all aspects of physiotherapy care and do not simply want treatment for pain. Patient characteristics were associated with what individual patients considered the most important reason for presenting to a private primary care physiotherapist. [McRae M, Hancock MJ (2017

    Full Text Available Background: Stroke is the third common cause of disability and death. Diagnosis of stroke is based on its clinical manifestations and/or observation of infarct in the neuroimaging. Standard battery of diagnostic investigations and classification criteria is required for detection of stroke etiology. Materials and Method: This review article deals with the diagnosis and management of brain infarction particularly in our country and is provided for non-neurologists. Using online scientific search engines and in some parts referring to laboratory archives constituted base of this review article.Results: Acute stroke management is almost similar in its various etiologies. Neuroprotective drugs have little value in acute stroke management. At present time, a few Iranian medical centers have infrastructure of thrombolysis therapy. Prevention of stroke is based on the detection and control of its risk factors. Aspirin, 80 mg per day is the most common drug for stroke prevention. Co-administration of aspirin 80 mg/d and Dipyridamole 200-400 mg/d increases the preventive effects of aspirin. Clopidogrel 75 mg/d is the stroke preventive drug of choice in patients with peptic ulcer and coronary artery disease. Co-administration of aspirin and clopidogrel is more effective in stroke prevention but has more hemorrhagic complications. Using warfarin for stroke prevention is suggested only in patients who have facilities for repetitive coagulation tests. Carotid endarterectomy is indicated in symptomatic patients with more than 70% stenosis of extracranial internal carotid artery, if performed only by vascular surgeons experienced in carotid surgery.Conclusion: Many stroke patients are managed by general practitioners and non-neurologists, e.g. internists, cardiologists and neurosurgeons.

    Full Text Available Congenital cytomegalovirus infection is a major cause of central nervous system and sensory impairments that affect cognition, motor function, hearing, language development, vestibular function, and vision. Although the importance of congenital cytomegalovirus infection is readily evident, the vast majority of maternal and fetal infections are not identified, even in developed countries. Multiple studies of prenatal cytomegalovirus infections have produced a body of knowledge that can inform the clinical approach to suspected or proven maternal and fetal infection. Reliable diagnosis of cytomegalovirus infection during pregnancy and accurate diagnosis of fetal infection are a reality. Approaches to preventing the transmission of cytomegalovirus from mother to fetus and to the treatment of fetal infection are being studied. There is evidence that public health approaches based on hygiene can dramatically reduce the rate of primary maternal cytomegalovirus infections during pregnancy. This review will consider the epidemiology of congenital cytomegalovirus infection, the diagnosis and management of primary infection during pregnancy, and approaches to preventing maternal infection.

    Full Text Available Aim: Diabetic retinopathy (DR and glaucoma are two most common retinal disorders that are major causes of blindness in diabetic patients. DR caused in retinal images due to the damage in retinal blood vessels, which leads to the formation of hemorrhages spread over the entire region of retina. Glaucoma is caused due to hypertension in diabetic patients. Both DR and glaucoma affects the vision loss in diabetic patients. Hence, a computer aided development of diagnosis system for Diabetic retinopathy and Glaucoma screening is proposed in this paper to prevent vision loss. Method: The diagnosis system of DR consists of two stages namely detection and segmentation of fovea and hemorrhages. The diagnosis system of glaucoma screening consists of three stages namely blood vessel segmentation, Extraction of optic disc (OD and optic cup (OC region and determination of rim area between OD and OC. Results: The specificity and accuracy for hemorrhages detection is found to be 98.47% and 98.09% respectively. The accuracy for OD detection is found to be 99.3%. This outperforms state-of-the-art methods. Conclusion: In this paper, the diagnosis system is developed to classify the DR and glaucoma screening in to mild, moderate and severe respectively.

    In Vietnam, no systematic prenatal toxoplasmosis screening is in place, and only few studies have assessed the prevalence and importance of this zoonotic parasite infection. In addition, no studies have been conducted to assess the risk factors associated with toxoplasmosis. This study protocol was developed to determine the seroprevalence of toxoplasmosis in pregnant women in Hanoi and Thai Binh, Northern Vietnam, and to evaluate the association with risk factors and congenital toxoplasmosis. The protocol was developed in a way that it could potentially evolve into a countrywide prenatal diagnosis and prevention program, with the main focus on primary prevention. The collaborating gynaecologists will invite eligible pregnant women attending antenatal care for the first time to participate in the study. At first consult, information about toxoplasmosis and its prevention will be provided. All participants will be asked to fill in a questionnaire, which is designed to analyse socio-demographic and biologically plausible risk factors associated with toxoplasmosis, and blood samples will be collected to determine the seroprevalence of toxoplasmosis in pregnant women. In case there is suspicion of a primary infection during pregnancy, the concerned women will be followed-up by the gynaecologists according to a predefined protocol. Every participant will be informed on her serological status, risk factors and prevention measures and is offered appropriate medical information and medical follow-up if required. The hypothesis is that congenital toxoplasmosis is an important but currently under-diagnosed public health problem in Vietnam. This study can strengthen sustainable control of toxoplasmosis in Vietnam, provide a protocol for prenatal diagnosis, boost overall awareness, improve the knowledge about toxoplasmosis prevention and can be essential for evidence-based health policy.

  4. Diagnosis, prevention and treatment of urinary tract infections in older people.

    2017-02-28

    Urinary tract infections (UTIs) are common in older people, with the prevalence increasing with age in both sexes. UTI is a frequent reason for emergency admission to hospital. There are many conditions that contribute to older people being more at risk of UTI and the main preventive strategy is to avoid the use of indwelling urethral catheters. Where an indwelling catheter is inserted its continued use should be regularly reviewed and the catheter removed, especially if the reason for insertion is incontinence and the person becomes additionally incontinent of faeces. Diagnosis of UTI can be complex because older people do not always exhibit the signs and symptoms commonly associated with UTI. Diagnosis can be further complicated by a person's inability to provide a comprehensive history and by difficulties obtaining an uncontaminated, 'clean catch' urine specimen. Antibiotic therapy should not be used routinely for people with asymptomatic bacteriuria and, where antibiotics are required, healthcare professionals should follow local prescribing guidelines.

    In subjects who present a first fasting plasma glucose (FPG 1 ) ≥7.0mmol/l without classic symptoms of diabetes, diagnosis of diabetes will likely be missed without an additional oral glucose tolerance test (OGTT) in the Chinese population. Recent studies have shown that glycated albumin (GA) has advantages in reflecting postprandial hyperglycemia. Therefore, the present study evaluated whether additional measurement of GA could reduce the rate of missed diagnosis of diabetes. A total of 1287 participants (711 men, 576 women) with a FPG 1 ≥7.0mmol/l without classic symptoms of diabetes were enrolled and underwent a 75-g OGTT. Serum GA was measured by a liquid enzyme method. Diabetes was diagnosed based on the 2010 American Diabetes Association (ADA) criteria. A total of 992 (77.08%) participants were diagnosed diabetes by OGTT and glycated hemoglobin A 1c (HbA 1c ). The diagnostic validity of 2-h postload plasma glucose (2hPG) was superior to other glycemic index (the diagnostic sensitivity of 2hPG, HbA 1c , the second FPG (FPG 2 ) was 87.50%, 73.99%, 63.21%, respectively). Without 2hPG after OGTT, repeat testing of FPG 2 alone would result in missed diagnosis of 36.79% of diabetic participants, whereas testing FPG 2 with HbA 1c was associated with a missed diagnosis rate of 14.31%. While using the combined criteria of FPG 2 ≥7.0mmol/l and/or HbA 1c ≥6.5% and/or GA≥17.1%, the rate of missed diagnosis was merely 9.48%. That is, the rate of missed diagnosis was reduced by 33.75% with the addition of GA measurement. The k value reflecting the consistency of diagnosis between the FPG 2 and/or HbA 1c and/or GA criteria and the 2010 ADA criteria was 0.788. For subjects with FPG 1 ≥7.0mmol/l without classic symptoms of diabetes, additional measurement of GA can help prevent missed diagnosis of diabetes in Chinese population.

    2018-02-01

    Full Text Available This paper reports the outcomes of a series of two Concussion Research Workshops held in Lowell, MA, USA. The workshop examined the state-of-the-art in concussion research, research challenges and the future directions of research within the following three core topic areas: (A Concussion Prevention Techniques & Technology, (B Concussion Diagnosis, and (C Treatment of Concussions. Concussions are a form of traumatic brain injury caused by an impact and are a growing concern among athletes and those who are involved with sports. Recent years have led to increasing awareness and research related to concussions with limited definitive understanding of the specific mechanism and pathology. Technology is beginning to take on an important role in the prevention, diagnosis and treatment of concussions. Currently, sensors provide data about the impact and the athlete. However, sensors and better protective equipment can enable an effective monitoring and thus protection of athletes. Only when a more definitive understanding of the injury mechanism is achieved, can sensors and protective equipment design contribute to effective monitoring and protection of athletes.

  11. Management of delayed hemolytic transfusion reaction in sickle cell disease: Prevention, diagnosis, treatment.

    Transfusion remains a key treatment of sickle cell disease complications. However, delayed hemolytic transfusion reaction, the most serious complication of transfusion, may be life-threatening if hyperhemolysis develops. This syndrome is generally underdiagnosed because its biological and clinical features resemble those of vaso-occlusive crisis, and red blood cell antibodies are frequently absent. Further transfusions may aggravate the symptoms, leading to severe multiple organ failure and death. It is therefore essential to prevent, diagnose and treat this syndrome efficiently. Prevention is based principally on the attenuation of allo-immunization through the provision of extended-matched RBCs or the use of rituximab. However, such treatment may be insufficient. Early diagnosis might make it possible to implement specific treatments in some cases, thereby avoiding the need for secondary transfusion. Diagnosis is dependent on the knowledge of the medical staff. Finally, many treatments, including steroids, immunoglobulins, erythropoietin and eculizumab, have been used to improve outcome. Improvements in our knowledge of the specific features of DHTR in SCD should facilitate management of this syndrome. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Congenital cytomegalovirus is the most frequent, yet under-recognised, infectious cause of newborn malformation in developed countries. Despite its clinical and public health importance, questions remain regarding the best diagnostic methods for identifying maternal and neonatal infection, and regarding optimal prevention and therapeutic strategies for infected mothers and neonates. The absence of guidelines impairs global efforts to decrease the effect of congenital cytomegalovirus. Data in the literature suggest that congenital cytomegalovirus infection remains a research priority, but data are yet to be translated into clinical practice. An informal International Congenital Cytomegalovirus Recommendations Group was convened in 2015 to address these questions and to provide recommendations for prevention, diagnosis, and treatment. On the basis of consensus discussions and a review of the literature, we do not support universal screening of mothers and the routine use of cytomegalovirus immunoglobulin for prophylaxis or treatment of infected mothers. However, treatment guidelines for infected neonates were recommended. Consideration must be given to universal neonatal screening for cytomegalovirus to facilitate early detection and intervention for sensorineural hearing loss and developmental delay, where appropriate. The group agreed that education and prevention strategies for mothers were beneficial, and that recommendations will need continual updating as further data become available.

    Sodium-glucose cotransporter 2 (SGLT2) inhibitors are the newest class of antihyperglycemic agents available on the market. Regulator warnings and concerns regarding the risk of developing diabetic ketoacidosis (DKA), however, have dampened enthusiasm for the class despite the combined glycemic, blood pressure, and occasional weight benefits of SGLT2 inhibitors. With the goal of improving patient safety, a cross-Canada expert panel and writing group were convened to review the evidence to-date on reported SGLT2 inhibitor-related DKA incidents and to offer recommendations for preventing and recognizing patients with SGLT2 inhibitor-associated DKA. Reports covering DKA events in subjects taking SGLT2 inhibitors that were published in PubMed, presented at professional conferences, or in the public domain from January 2013 to mid-August 2016 were reviewed by the group independently and collectively. Practical recommendations for diagnosis and prevention were established by the panel. DKA is rarely associated with SGLT2 inhibitor therapy. Patients with SGLT2 inhibitor-associated DKA may be euglycemic (plasma glucose level diabetes, including those with type 2 diabetes, and is typically precipitated by insulin omission or dose reduction, severe acute illness, dehydration, extensive exercise, surgery, low-carbohydrate diets, or excessive alcohol intake. SGLT2 inhibitor-associated DKA may be prevented by withholding SGLT2 inhibitors when precipitants develop, avoiding insulin omission or inappropriate insulin dose reduction, and by following sick day protocols as recommended. Preventive strategies should help avoid SGLT2 inhibitor-associated DKA. All SGLT2 inhibitor-treated patients presenting with signs or symptoms of DKA should be suspected to have DKA and be investigated for DKA, especially euglycemic patients. If DKA is diagnosed, SGLT2 inhibitor treatment should be stopped, and the DKA should be treated with a traditional treatment protocol. Copyright © 2016 Elsevier

    One third of the earths population is infected with Mycobacterium tuberculosis (Mtb), but only 5-10% of the infected individuals develop active tuberculosis (TB) over their lifetime. The remaining 90-95% stay healthy and are called latently infected individuals. They are the biggest reservoir of the tubercle bacilli and identifying the cases of latent TB is a part of the global plan of TB control. From the clinical point of view detection of latent TB infections (LTBI) in individuals with the highest active TB risk including cases of HIV infection, autoimmune inflammatory diseases or cancer, is a priority. This review summarizes the recent findings in the pathogenesis of latent TB, its diagnosis, treatment and prevention.

    The purpose of this literature review is to provide a better understanding of the impact that environmental design can have on the process of cancer prevention, diagnosis, treatment, and survivorship. Cancer is considered a chronic disease in the United States, and more than 1.6 million new cases are diagnosed annually. New strategies of cancer care propose patient-centered services to achieve the best outcome, and researchers have found that environmental design can be an important part of improving this care. Searches were conducted in the PubMed and Google Scholar databases as well as in specific healthcare design journals such as Health Environments Research & Design, Environmental Psychology, and Environment and Behavior. The criteria for articles included in the review were (a) English-language articles related to facility design, which addressed (b) the topics of built environment in relation to cancer diagnosis, treatment, and survivorship, and were (c) published in peer-reviewed journals between 2000 and 2017. Finally, 10 articles were selected, and the contents were analyzed. The selected articles demonstrate that environmental design is one of the critical factors for success throughout the whole continuum of cancer care from diagnosis to end-of-treatment. Some of the specific conclusions from the review are that "neighborhood-oriented" design strategies can be beneficial (by providing accessibility to all facilities along the patient's path), that access to nature for patients, staff, and visitors alike is associated with better outcomes, and that provisions for natural lighting and noise reduction are associated with cancer patients' well-being.

    Hypertension Canada provides annually updated, evidence-based guidelines for the diagnosis, assessment, prevention, and treatment of hypertension. This year, we introduce 10 new guidelines. Three previous guidelines have been revised and 5 have been removed. Previous age and frailty distinctions have been removed as considerations for when to initiate antihypertensive therapy. In the presence of macrovascular target organ damage, or in those with independent cardiovascular risk factors, antihypertensive therapy should be considered for all individuals with elevated average systolic nonautomated office blood pressure (non-AOBP) readings ≥ 140 mm Hg. For individuals with diastolic hypertension (with or without systolic hypertension), fixed-dose single-pill combinations are now recommended as an initial treatment option. Preference is given to pills containing an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker in combination with either a calcium channel blocker or diuretic. Whenever a diuretic is selected as monotherapy, longer-acting agents are preferred. In patients with established ischemic heart disease, caution should be exercised in lowering diastolic non-AOBP to ≤ 60 mm Hg, especially in the presence of left ventricular hypertrophy. After a hemorrhagic stroke, in the first 24 hours, systolic non-AOBP lowering to < 140 mm Hg is not recommended. Finally, guidance is now provided for screening, initial diagnosis, assessment, and treatment of renovascular hypertension arising from fibromuscular dysplasia. The specific evidence and rationale underlying each of these guidelines are discussed. Copyright © 2017 Canadian Cardiovascular Society. Published by Elsevier Inc. All rights reserved.

    Full Text Available Hemoglobinopathies (HBP are the most common genetic disorder in Oman and are in need of prevention programs due to the high incidence of β-thalassemia major and sickle cell disease. Prenatal diagnosis (PD and selective pregnancy termination is shown to be the most effective prevention tool for the control of HBP. However, PD is not available in Oman thus far because abortion is subject to religious, cultural and ethical issues. We have examined the attitude of a number of Omani HBP carrier couples towards prenatal diagnosis and selective abortion. We have interviewed 35 couples at risk visiting the main premarital clinic in Muscat between Jan 2011 and Jan 2012. Couples were interviewed using a pre-structured questionnaire. The majority would have accepted prenatal diagnosis (94% if the service would be available in the country but pregnancy termination was greatly influenced by religious values. 血红蛋白病(HBP)是一种在阿曼最常见的遗传性疾病,由于其高发的B型地中海贫血症及镰状细胞症,相关的预防措施对于这一国家来说,相当重要。产前诊断(PD)和选择性终止妊娠被证实是针对管控血红蛋白病(HBP)的最有效方法。然而,由于受到宗教、文化和伦理抵制堕胎的影响,产前诊断(PD)并不能在该国得以应用。我们对该国一部分血红蛋白病患夫妇做了一项关于产前诊断的意向调查。2011年一月至2012年一月,我们在马斯喀特(阿曼首都)的一家婚前诊所对35对夫妇做了相关的采访调查。调查的问卷是事先设置好的。大部分(94%)夫妇表示接受产前诊断如果相应的措施能得到广泛的普及,但是他们对于选择性终止妊娠的态度受到了其宗教价值观的极大影响。

    Full Text Available Background. We aim to provide useful evidence about the association of neutrophil-to-lymphocyte ratio (NLR and platelet-to-lymphocyte ratio (PLR with idiopathic sudden sensorineural hearing loss (ISSNHL and its possibility of emerging as a cheap, reliable, and independent prognostic marker of ISSNHL. Methods. 348 patients diagnosed with ISSNHL were included in our retrospective data analysis. Blood samples and the hearing assessments of the patients were carried out. Then, the patients were divided into 2 groups as “recovered” and “unrecovered” according to their response to the treatment. Results. Both mean NLR and PLR values of the ISSNHL patients were significantly higher than the control group (both P<0.001. The NLR value was 5.98±4.22 in the unrecovered group and 3.50±3.38 in the recovered group (P<0.001. After adjustment in a binary logistic regression model, only NLR value was associated with the recovery of ISSNHL (P=0.001. Discussion. We demonstrated for the first time that NLR and PLR values were significantly high in ISSNHL patients. Also the NLR level might be taken into account as a novel potential marker to predict the patients’ prognosis in terms of recovery.

    To evaluate the sensitivity and specificity of conventional CT of abdomen in the detection of esophageal varices, and to correlate CT grade of esophageal varices with prognosis and risk for bleeding. Both CT and endoscopy were performed in 100 patients. Endoscopy revealed that while 54 patients had varices, 46 did not. CT criteria of variceal grading were follows;(1) wallthickening of more than 5 mm or irregular wall contour(grade 1):(2) intraluminal protruding tubular structures with contrast enhancement(grade II);(3) confluent varices in the wall of esophagus or multiplied paraesophageal collaterals(gradeIII). CT were reviewed by three radiologists without reference to clinical and endoscopic data. Sensitivity and specificity of CT in the detection of esophageal varices were 80%, retrospectively. CT and endoscopic grades agreed with each other in 68% of patients, and there was high correlation between CT and endoscopy. (Gamma statistics, p=0.828). No history or endoscopic evidence of variceal bleeding was present on grade I, but there was a high incidence on grade II(35%) and on grade III(50%)(MH Chi-Square, Ridit scores=50.561, p=0.000). Abdominal CT is useful in the detection of esophageal varices, and can predict the risk factors of bleeding in patients with chronic liver diseases

    Scientific advances in cariology in the past 150 years have led to the understanding that dental caries is a chronic, dietomicrobial, site-specific disease caused by a shift from protective factors favoring tooth remineralization to destructive factors leading to demineralization. Epidemiologic data indicate that caries has changed in the last century; it now is distributed unequally in the U.S. population. People who are minorities, homeless, migrants, children with disabilities and of lower socioeconomic status suffer from the highest prevalence and severity of dental caries. Scientific advances have led to improvements in the prevention, diagnosis and treatment of dental caries, but there is a need for new diagnostic tools and treatment methods. and Future management of dental caries requires early detection and risk assessment if the profession is to achieve timely and cost-effective prevention and treatment for those who need it most. Dental professionals look forward to the day when people of all ages and backgrounds view dental caries as a disease of the past.

    Hepatocellular carcinoma (HCC) has been one of the most fatal malignant tumors worldwide and its associated morbidity and mortality remain of significant concern. Based on in-depth reviews of serological diagnosis of HCC, in addition to AFP, there are other biomarkers: Lens culinaris agglutinin-reactive AFP (AFP-L3), des- carboxyprothrombin (DCP), tyrosine kinase with Ig and eprdermal growth factor (EGF) homology domains 2 (TIE2)-espressing monocytes (TEMs), glypican-3 (GPC3), Golgi protein 73 (GP73), interleukin-6 (IL-6), and squamous cell carcinoma antigen (SCCA) have been proposed as biomarkers for the early detection of HCC. The diagnosis of HCC is primarily based on noninvasive standard imaging methods, such as ultrasound (US), dynamic multiphasic multidetector-row CT (MDCT) and magnetic resonance imaging (MRI). Some experts advocate gadolinium diethyl-enetriamine pentaacetic acid (Gd-EOB-DTPA) MRI and contrast-enhanced US as the promising imaging madalities of choice. With regard to recent advancements in tissue markers, many cuting-edge technologies using genome-wide DNA microarrays, qRT-PCR, and proteomic and inmunostaining studies have been implemented in an attempt to identify markers for early diagnosis of HCC. Only less than half of HCC patients at initial diagnosis are at an early stage treatable with curative options: local ablation, surgical resection, or liver transplant. Transarterial chemoembolization (TACE) is considered the standard of care with palliation for intermediate stage HCC. Recent innovative procedures using drug-eluting-beads and radioembolization using Yttrium-90 may exhibit beneficial effects in HCC treatment. During the past few years, several molecular targeted agents have been evaluated in clinical trials in advanced HCC. Sorafenib is currently the only approved systemic treatment for HCC. It has been approved for the therapy of asymptomatic HCC patients with well-preserved liver function who are not candidates for potentially

    Human cytomegalovirus (CMV) is under-recognised, despite being the leading infectious cause of congenital malformation, affecting ~0.3% of Australian live births. Approximately 11% of infants born with congenital CMV infection are symptomatic, resulting in clinical manifestations, including jaundice, hepatosplenomegaly, petechiae, microcephaly, intrauterine growth restriction and death. Congenital CMV infection may cause severe long-term sequelae, including progressive sensorineural hearing loss and developmental delay in 40-58% of symptomatic neonates, and ~14% of initially asymptomatic infected neonates. Up to 50% of maternal CMV infections have nonspecific clinical manifestations, and most remain undetected unless specific serological testing is undertaken. The combination of serology tests for CMV-specific IgM, IgG and IgG avidity provide improved distinction between primary and secondary maternal infections. In pregnancies with confirmed primary maternal CMV infection, amniocentesis with CMV-PCR performed on amniotic fluid, undertaken after 21-22 weeks gestation, may determine whether maternofetal virus transmission has occurred. Ultrasound and, to a lesser extent, magnetic resonance imaging are valuable tools to assess fetal structural and growth abnormalities, although the absence of fetal abnormalities does not exclude fetal damage. Diagnosis of congenital CMV infection at birth or in the first 3 weeks of an infant's life is crucial, as this should prompt interventions for prevention of delayed-onset hearing loss and neurodevelopmental delay in affected infants. Prevention strategies should also target mothers because increased awareness and hygiene measures may reduce maternal infection. Recognition of the importance of CMV in pregnancy and in neonates is increasingly needed, particularly as therapeutic and preventive interventions expand for this serious problem. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    A patient with a history of chronic alcohol abuse and metal disorders developed a coma due to Marchiafava-Bignami disease. A computed tomography study of the brain was normal, whereas magnetic resonance imaging disclosed a solitary circumscribed lesion in the middle part of the corpus callosum, generating a hypointense signal on T1 images and a hyperintense signal on T2 images. The outcome was favorable. A previous magnetic resonance imaging study done after the onset of the mental disorders was normal, supporting a diagnosis of acute regressive rather than mixed Marchiafava-Bignami disease.

    Full Text Available Aim. To reveal peculiarities of arterial hypertension (AH diagnosis and therapy and their matching with international and national guidelines on AH. Material and Methods. An interview among Moscow physicians dealing with hypertensive patients was conducted in April-June 2005. Interview was taken with specially worked out forms containing 15 questions about hypertensive patient management. 102 physicians took part in interviewing, among them 65 internists and 37 cardiologists. Among interviewed physicians 56 ones were from outpatient clinics, 19 - from diagnostic centers, 14 - from hospitals, 5 - from commercial medical centers, 4 - from research center and 3 physicians had private practice.  Results. 80,4% of interviewed physicians correctly determined the main goals of AH therapy. 16% of doctors did not indicate blood pressure level below 140/90 mm Hg as target level of secondary prevention. Mainly antihypertensive therapy was presented by four classes of medicines, their shares were as follow: ACE inhibitors - 35%, beta-blockers – 28%, diuretics – 26% and calcium antagonists – 10%. Other classes of antihypertensive medicines (antagonists of angiotensin-II receptors, central acting medicines made about 1% of share. When choosing original medicine among several suggested trade marks, only 22% of doctors defined the medicine correctly. Original medicines made only 29,4% prescriptions in real medical practice. Conclusion. Real practice of AH diagnosis and therapy considerably differs from international and national guidelines on AH. It is possibly related with lack of appropriate knowledge among physicians as well as problems in public health service.

    Full Text Available OBJECTIVE: To assess the prognostic and diagnostic value of whole blood impedance aggregometry in patients with sepsis and SIRS and to compare with whole blood parameters (platelet count, haemoglobin, haematocrit and white cell count. METHODS: We performed an observational, prospective study in the acute setting. Platelet function was determined using whole blood impedance aggregometry (multiplate on admission to the Emergency Department or Intensive Care Unit and at 6 and 24 hours post admission. Platelet count, haemoglobin, haematocrit and white cell count were also determined. RESULTS: 106 adult patients that met SIRS and sepsis criteria were included. Platelet aggregation was significantly reduced in patients with severe sepsis/septic shock when compared to SIRS/uncomplicated sepsis (ADP: 90.7±37.6 vs 61.4±40.6; p<0.001, Arachadonic Acid 99.9±48.3 vs 66.3±50.2; p = 0.001, Collagen 102.6±33.0 vs 79.1±38.8; p = 0.001; SD ± mean. Furthermore platelet aggregation was significantly reduced in the 28 day mortality group when compared with the survival group (Arachadonic Acid 58.8±47.7 vs 91.1±50.9; p<0.05, Collagen 36.6±36.6 vs 98.0±35.1; p = 0.001; SD ± mean. However haemoglobin, haematocrit and platelet count were more effective at distinguishing between subgroups and were equally effective indicators of prognosis. Significant positive correlations were observed between whole blood impedance aggregometry and platelet count (ADP 0.588 p<0.0001, Arachadonic Acid 0.611 p<0.0001, Collagen 0.599 p<0.0001 (Pearson correlation. CONCLUSIONS: Reduced platelet aggregometry responses were not only significantly associated with morbidity and mortality in sepsis and SIRS patients, but also correlated with the different pathological groups. Whole blood aggregometry significantly correlated with platelet count, however, when we adjust for the different groups we investigated, the effect of platelet count appears to be non-significant.

    Study Design Retrospective review with telephone follow-up. Background Acute spondylolytic injuries have a dramatic impact on the young athlete. Excellent short-term clinical outcomes have been observed, but not enough is known about long-term clinical outcomes. Objectives (1) To report long-term clinical outcomes for patients diagnosed with acute spondylolysis, and (2) to assess the prognostic ability of retrospective variables for long-term outcomes. Methods Patients from 2010 through 2013 were retrospectively reviewed to identify patients and to obtain demographic, baseline, and short-term outcomes. Long-term follow-up data were collected by telephone from patients diagnosed with acute spondylolysis to assess recurrence rate of low back pain, perceived outcome, pain, and functional ability. Patients were categorized as having a good or poor long-term outcome based on these measures. Logistic regression analysis was performed to assess the prognostic ability of the retrospective variables for long-term outcomes 3.4 years (range, 1.5-5.6 years) after treatment. Results One hundred twenty-one (71.6%) patients completed the follow-up questionnaire (48 female; mean age at baseline, 14.4 years). At follow-up, 81 (66.9%) patients were able to maintain their same or a higher level of sport. Recurrence of significant symptoms was reported by 55 (45.5%) patients, with 41 (33.9%) requiring medical treatment. The final logistic regression model revealed that female sex, adverse reaction during care, and multilevel injury were significant predictors of poor long-term outcome (R 2 = 0.22). Conclusion Although excellent short-term outcomes were noted, 42% of patients reported a poor outcome at long-term follow-up. Female sex, multilevel injury, and experiencing an adverse reaction during care were significant predictors of poor long-term clinical outcome for patients diagnosed with acute spondylolysis.

    Full Text Available OBJETIVO: Avaliar a postura de médicos frente à informação do diagnóstico e prognóstico de câncer aos pacientes, familiares ou ambos, incluindo uma análise bioética do conflito verificado entre beneficência, respeito à autonomia do paciente e paternalismo. MÉTODOS: Foram entrevistados 38 médicos responsáveis por pacientes com neoplasias malignas em um hospital terciário. O questionário foi dividido em duas partes. Uma com dados gerais do entrevistado e outra com perguntas específicas sobre a transmissão das informações ao paciente e também avaliação da compreensão do médico sobre beneficência. RESULTADOS: Embora 97,4% dos médicos em geral informem o diagnóstico aos seus pacientes, nos casos de doença terminal, 50% se valem da família como apoio. Com relação à informação sobre prognóstico fatal, os que comunicam somente à família foram 63,1%, enquanto 31,6% preferem passar a informação diretamente ao paciente. O estudo mostrou que os profissionais confundem beneficência com paternalismo. CONCLUSÃO: Os médicos têm o hábito de informar o diagnóstico aos seus pacientes. Na impossibilidade de recursos curativos, as atitudes tornam-se conflitantes no que concerne aos princípios da beneficência e autonomia. O número de médicos que acreditam no paternalismo como forma de beneficência é ainda significativo. A atitude paternalista emerge principalmente quando os recursos terapêuticos tornam-se não resolutivos.Biotechnological scientific progress has brought about some misunderstanding between advances and ethical decisions. The relationship physician-patient when facing seriously ill patients has been altered.

    Lipids have important functions in the human body, but high serum cholesterol level is an important risk factor for cardiovascular and cerebrovascular diseases. Prevention of stroke includes modifying risk factors, like dyslipidemias. Based on this theory, we examined in practice the possible role of a public care neurology and stroke department with a large patient turnover in vascular risk screening with regard to the diagnosis of hyperlipidemia. We reviewed all the medical records (irrespective of disease group;) of patients hospitalized in 2007 at Department of Neurclogy and Stroke Center of Szent János Hospital of the Municipality of the City of Budapest. Patients included in the study were classified into three groups: (1) those admitted with acute stroke; (2) those with a history of acute stroke, but without evidence of a novel cerebrovascular event; (3) no history and evidence of cerebrovascular disease during hospitalization. Our data show that 17.6% of patients was diagnosed with hyperlipidemia during hospital care, and another 18.5% was known to have elevated cholesterol levels. Altogether, 36.1% of the 1438 patients evaluated had hyper ipidemia. Known hypercholesterolemia was 18.4% in patierts admitted for acute stroke, 26.9% in patients formerly (but not currently) treated for cerebrovascular disease, and 13.6% in the third group. Newly diagnosed elevated cholesterol levels had highest rate (22.6%) in former stroke patierts (currently treated for other diseases); 20.4% in patients with acute stroke, and 13.2% in the third group. In the first two groups, the number of patients newly diagnosed with elevated serum cholesterol almost equaled to those with already known hypercholesterolemia. Based on our data, neurology departments have an important role in diagnosing hyperlipidemia and vascular prevention.

  14. Early diagnosis of the urofacial syndrome is essential to prevent irreversible renal failure

    Full Text Available INTRODUCTION: The urofacial or Ochoa syndrome is a rare disease characterized by the presence of functional obstructive uropathy associated with peculiar facial features when patients attempt to smile or laugh. Unfortunately, many of these patients remain without proper diagnosis or adequate treatment due to lack of recognition of the disease. This can ultimately result in upper tract deterioration and eventual renal failure. We present our experience with this rare syndrome. MATERIALS AND METHODS: We identified 3 patients who presented initially with acute renal failure, urinary tract infection (UTI and severe dysfunctional elimination. All patients were thoroughly evaluated, including screening for spinal cord anomalies, and were subsequently diagnosed with urofacial syndrome. RESULTS: At the outset, the two older patients (aged 4 and 9 years presented with the typical facial features when attempting to smile or laugh. One patient in the newborn period presented with urinary and fecal retention and septicemia and, to our knowledge, represents the youngest case of urofacial syndrome reported so far. All patients were evaluated with ultrasonography, renal scan, voiding cystourethrogram (VCUG and urodynamics. Findings included hydronephrosis and a thick-walled, trabeculated bladder with poor compliance and detrusor hypereflexia respectively in each patient. All were subsequently treated with clean intermittent catheterization (CIC, antibiotic prophylaxis and anticholinergic therapy. One patient required appendicovesicostomy for CIC due to discomfort secondary to a sensate urethra. CONCLUSIONS: Our series demonstrates that early recognition of this rare syndrome is necessary to adequately treat and prevent upper tract deterioration in these unique individuals. Although the urofacial is difficult to diagnose in infants, cognizance must be maintained in order to prevent severe subsequent sequalae.

    Neuroendocrine tumors (NETs) are rare neoplasms that emerge mainly from the GI tract, pancreas and respiratory tract. The incidence of NETs has increased more than sixfold in the last decades. NETs typically express somatostatin receptors on their cell surface, which can be targeted by 'cold' somatostatin analogs for therapy or by 'hot' radiolabeled somatostatin analogs for tumor localization and treatment. 68-Gallium-DOTA peptides (DOTATATE, DOTATOC, DOTANOC) positron emission tomography/computed tomography is a highly accurate imaging modality for NETs that has been found to be more sensitive for NET detection than other imaging modalities. In the current review, we will discuss the clinical utility of 68-Gallium-DOTATATE positron emission tomography/computed tomography for the diagnosis and management of patients with NETs.

    Full Text Available Background: The macro-aggregated albumin lung perfusion scan (99mTc-MAA is a diagnostic method for hepatopulmonary syndrome (HPS. Aim: To determine the sensitivity of 99mTc-MAA in diagnosing HPS, to establish the utility of 99mTc-MAA in determining the influence of HPS on hypoxemia in patients with concomitant pulmonary disease and to determine the correlation between 99mTc-MAA values and other respiratory parameters. Methods: Data from 115 cirrhotic patients who were eligible for liver transplantation (LT were prospectively analyzed. A transthoracic contrast echocardiography and 99mTc-MAA were performed in 85 patients, and 74 patients were diagnosed with HPS. Results: The overall sensitivity of 99mTc-MAA for the diagnosis of HPS was 18.9% (14/74 in all of the HPS cases and 66.7% (4/6 in the severe to very severe cases. In HPS patients who did not have lung disease, the degree of brain uptake of 99mTc-MAA was correlated with the alveolar-arterial oxygen gradient (A-a PO2 (r = 0.32, p < 0.05 and estimated oxygen shunt (r = 0.41, p < 0.05 and inversely correlated with partial pressure of arterial oxygen (PaO2 while breathing 100% O2 (r = -0.43, p < 0.05. The 99mTc-MAA was positive in 20.6% (7/36 of the patients with HPS and lung disease. The brain uptake of 99mTc-MAA was not associated with mortality and normalized in all cases six months after LT. Conclusions: The 99mTc-MAA is a low sensitivity test for the diagnosis of HPS that can be useful in patients who have concomitant lung disease and in severe to very severe cases of HPS. It was not related to mortality, and brain uptake normalized after LT.

    The soluble Fms-like tyrosine kinase 1 (sFlt-1)/placental growth factor (PlGF) ratio has been introduced as a biomarker for diagnosing preeclampsia (PE) and the prediction of adverse pregnancy outcome. In a cohort of pregnant women with PE or at high risk of PE, the additive value of the sFlt-1/PlGF ratio for diagnosing PE and prediction of adverse pregnancy outcomes was investigated. From September 2011 until August 2013 patients with suspected or confirmed clinical PE were recruited at the Erasmus MC. At time of admission, blood for measurement of sFlt-1 and PlGF was obtained. A sFlt-1/PlGF ratio of >85 was considered suggestive for PE. Clinical characteristics and pregnancy outcomes were retrieved from medical records. The clinical diagnosis of PE was made based on the ISSHP criteria, whereas the fullPIERS definition was used for the rating of adverse pregnancy outcomes. A total of 96 patients were included. Of the patients, 53 (55%) met the clinical criteria of PE at time of blood sampling. In 11% of these patients (n = 6) the ratio was 85 (false positive), resulting in positive and negative predictive values of 89% and 86% respectively. Three patients without clinical PE, but with a positive ratio, developed superimposed PE and 2 developed an adverse pregnancy outcome. In 2 of the 6 patients with clinical PE but a negative ratio, an adverse pregnancy outcome was encountered. Using a binary regression model with adjustment for gestational age < 34 weeks, clinical PE was associated with a 9 times increased risk for an adverse outcome, while this was 29 times for an elevated ratio (P = 0.036). The additive value of an increased ratio for diagnosing PE is limited since most patients with clinical PE also have a positive ratio. An elevated ratio is superior to the clinical diagnosis of PE for predicting an adverse pregnancy outcome.

    Cancer patients pose an increased risk of infectious complications due to their underlying disease and its treatment. The present guidelines, developed by the Commission of Infections in the Immunocompromised Host of the Argentine Society of Infectious Diseases are an updated version of those published in 2008. For the elaboration of these guidelines, both the scientific evidence and the local experience were thoroughly evaluated. This Consensus includes an overview of the risk factors and the epidemiology of infections in both adult and pediatric cancer patients. It deals with the management of the febrile neutropenic patient, the risk categorization, the initial empirical therapy in the multiresistant era and its subsequent management. It includes a section dedicated to the antifungal empirical and directed therapy as well as the diagnosis and treatment of the most frequent fungal infections. Prevention strategies, both general and for high-risk patients, including those receiving biologic response modifiers, are herein shown. These guidelines should be applied in conjunction with a careful clinical evaluation and taking into account local epidemiological factors. Copyright © 2014 Asociación Colombiana de Psiquiatría.

    Human leukocyte antigen-G (HLA-G) is a non-classical HLA class I molecule that differs from classical HLA class I molecules by low polymorphism and tissue distribution. HLA-G is a tolerogenic molecule with an immune-modulatory and anti-inflammatory function on both innate and adaptative immunity. This peculiar characteristic of HLA-G has led to investigations of its role in pathological conditions in order to define possible uses in diagnosis, prevention and treatment. In recent years, HLA-G has been shown to have an important implication in different inflammatory and autoimmune diseases, pregnancy complications, tumor development and aggressiveness, and susceptibility to viral infections. In fact, HLA-G molecules have been reported to alternate at both genetic and protein level in different disease situations, supporting its crucial role in pathological conditions. Specific pathologies show altered levels of soluble (s)HLA-G and different HLA-G gene polymorphisms seem to correlate with disease. This review aims to update scientific knowledge on the contribution of HLA-G in managing pathological conditions. PMID:25237627

    Preimplantation genetic diagnosis (PGD) allows birth of unaffected children for couples at risk for a genetic disorder. We present the strategy and outcome of PGD for four lysosomal storage disorders (LSD): Tay-Sachs disease (TSD), Gaucher disease (GD), Fabry disease (FD), and Hunter syndrome (HS), and subsequent development of stem cell lines. For each disease, we developed a family-specific fluorescent multiplex single-cell PCR protocol that included the familial mutation and informative markers surrounding the mutation. Embryo biopsy and PGD analysis were performed on either oocytes (polar bodies one and two) or on single blastomeres from a six-cell embryo. We treated twenty families carrying mutations in these lysosomal storage disorders, including 3 couples requiring simultaneous analysis for two disorders (TSD/GD, TSD/balanced Robertsonian translocation 45XYder(21;14), and HS/oculocutaneus albinism). These analyses led to an overall pregnancy rate/embryo transfer of 38% and the birth of 20 unaffected children from 17 families. We have found that PGD for lysosomal disorders is a safe and effective method to prevent birth of affected children. In addition, by using mutant embryos for the derivation of stem cell lines, we have successfully established GD and HS hESC lines for use as valuable models in LSD research.

  2. Utility of ketone measurement in the prevention, diagnosis and management of diabetic ketoacidosis.

    2015-01-01

    Ketone measurement is advocated for the diagnosis of diabetic ketoacidosis and assessment of its severity. Assessing the evidence base for ketone measurement in clinical practice is challenging because multiple methods are available but there is a lack of consensus about which is preferable. Evaluating the utility of ketone measurement is additionally problematic because of variability in the biochemical definition of ketoacidosis internationally and in the proposed thresholds for ketone measures. This has led to conflicting guidance from expert bodies on how ketone measurement should be used in the management of ketoacidosis. The development of point-of-care devices that can reliably measure the capillary blood ketone β-hydroxybutyrate (BOHB) has widened the spectrum of applications of ketone measurement, but whether the evidence base supporting these applications is robust enough to warrant their incorporation into routine clinical practice remains unclear. The imprecision of capillary blood ketone measures at higher values, the lack of availability of routine laboratory-based assays for BOHB and the continued cost-effectiveness of urine ketone assessment prompt further discussion on the role of capillary blood ketone assessment in ketoacidosis. In the present article, we review the various existing methods of ketone measurement, the precision of capillary blood ketone as compared with other measures, its diagnostic accuracy in predicting ketoacidosis and other clinical applications including prevention, assessment of severity and resolution of ketoacidosis. © 2014 The Authors.

    Primary biliary cirrhosis (PBC) may be associated with various rheumatological disorders. To investigate the frequency and significance of 'rheumatological' antinuclear antibodies in the field of autoimmune chronic liver disease, with special regard to PBC. We studied 105 patients with PBC, 162 autoimmune liver disease controls (type 1 and 2 autoimmune hepatitis, primary sclerosing cholangitis), 30 systemic lupus erythematosus and 50 blood donors. Sera were tested for the presence of antibodies to extractable nuclear antigens (anti-ENA) by counterimmunoelectrophoresis, enzyme-linked and immunoblot (IB) assay, and for the presence of anti-centromere antibodies (ACA) by indirect immunofluorescence on HEp-2 cells and IB. The overall prevalence of IB-detected anti-ENA in PBC (30%) was higher than in type 1 autoimmune hepatitis (2.5%, P < 0.0001), type 2 autoimmune hepatitis (0%, P < 0.0001) and primary sclerosing cholangitis (11.5%, P = 0.006) and lower than in systemic lupus erythematosus (53%, P = 0.03). The most frequent anti-ENA reactivity in PBC was anti-SSA/Ro-52kD (28%). ACA were detected by IB in 21% PBC patients and never in the other subjects (P < 0.0001). Anti-SS-A/Ro/52kD positive PBC patients had at the time of diagnosis a more advanced histological stage (P = 0.01) and higher serum levels of bilirubin (P = 0.01) and IgM (P = 0.03) compared with negative ones. In the autoimmune liver disease setting, anti-SS-A/Ro-52kD and ACA have a high specificity for PBC and can thus be of diagnostic relevance in anti-mitochondrial antibodies negative cases. If confirmed in further studies with adequate follow-up, anti-SS-A/Ro-52kD antibodies might identify PBC patients with a more advanced and active disease.

  6. Obesity as a risk factor for development and poor prognosis of breast cancer.

    Carmichael, A R

    2006-10-01

    The evidence that obesity adversely affects women's health is overwhelming and indisputable. The risk of postmenopausal breast cancer increases with obesity; measured as weight gain, body mass index, waist-hip ratio or percent body fat. It is also established that obesity is associated with poor prognosis of breast cancer. This review examines in detail the possible mechanisms by which obesity causes poor prognosis of breast cancer such as estrogenic activity, advanced or more aggressive disease at diagnosis and high likelihood of both local and systemic treatment failure. After careful consideration of the available evidence, the author concludes that obesity contributes towards development and poor prognosis of breast cancer; therefore, weight management should be an integral part of any strategy to prevent and improve the outcome of breast cancer.

    Curcumin derived from turmeric is well documented for its anti-carcinogenic, antioxidant and anti-inflammatory properties. Recent studies show that curcumin also possesses neuroprotective and cognitive-enhancing properties that may help delay or prevent neurodegenerative diseases, including Alzheimer's disease (AD). Currently, clinical diagnosis of AD is onerous, and it is primarily based on the exclusion of other causes of dementia. In addition, phase III clinical trials of potential treatments have mostly failed, leaving disease-modifying interventions elusive. AD can be characterised neuropathologically by the deposition of extracellular β amyloid (Aβ) plaques and intracellular accumulation of tau-containing neurofibrillary tangles. Disruptions in Aβ metabolism/clearance contribute to AD pathogenesis. In vitro studies have shown that Aβ metabolism is altered by curcumin, and animal studies report that curcumin may influence brain function and the development of dementia, because of its antioxidant and anti-inflammatory properties, as well as its ability to influence Aβ metabolism. However, clinical studies of curcumin have revealed limited effects to date, most likely because of curcumin's relatively low solubility and bioavailability, and because of selection of cohorts with diagnosed AD, in whom there is already major neuropathology. However, the fresh approach of targeting early AD pathology (by treating healthy, pre-clinical and mild cognitive impairment-stage cohorts) combined with new curcumin formulations that increase bioavailability is renewing optimism concerning curcumin-based therapy. The aim of this paper is to review the current evidence supporting an association between curcumin and modulation of AD pathology, including in vitro and in vivo studies. We also review the use of curcumin in emerging retinal imaging technology, as a fluorochrome for AD diagnostics.

  8. ACE-I Angioedema: Accurate Clinical Diagnosis May Prevent Epinephrine-Induced Harm

    Directory of Open Access Journals (Sweden)

    R. Mason Curtis

    2016-06-01

    Full Text Available Introduction: Upper airway angioedema is a life-threatening emergency department (ED presentation with increasing incidence. Angiotensin-converting enzyme inhibitor induced angioedema (AAE is a non-mast cell mediated etiology of angioedema. Accurate diagnosis by clinical examination can optimize patient management and reduce morbidity from inappropriate treatment with epinephrine. The aim of this study is to describe the incidence of angioedema subtypes and the management of AAE. We evaluate the appropriateness of treatments and highlight preventable iatrogenic morbidity. Methods: We conducted a retrospective chart review of consecutive angioedema patients presenting to two tertiary care EDs between July 2007 and March 2012. Results: Of 1,702 medical records screened, 527 were included. The cause of angioedema was identified in 48.8% (n=257 of cases. The most common identifiable etiology was AAE (33.1%, n=85, with a 60.0% male predominance. The most common AAE management strategies included diphenhydramine (63.5%, n=54, corticosteroids (50.6%, n=43 and ranitidine (31.8%, n=27. Epinephrine was administered in 21.2% (n=18 of AAE patients, five of whom received repeated doses. Four AAE patients required admission (4.7% and one required endotracheal intubation. Epinephrine induced morbidity in two patients, causing myocardial ischemia or dysrhythmia shortly after administration. Conclusion: AAE is the most common identifiable etiology of angioedema and can be accurately diagnosed by physical examination. It is easily confused with anaphylaxis and mismanaged with antihistamines, corticosteroids and epinephrine. There is little physiologic rationale for epinephrine use in AAE and much risk. Improved clinical differentiation of mast cell and non-mast cell mediated angioedema can optimize patient management.

    Gastrointestinal stromal tumors (GIST) are mesenquimal tumors derived from cell precursors. They have the capacity for myogenic and neurogenic differentiation and are characterized by expression of KIT protein /tyrosine kinase growth factor). Clinically, they exhibit various biological behaviors. We present 8 cases of GIST, describing both their radiological manifestation through computerized tomography (CT) and most accepted criteria for benignity and malignancy. We also describe the response of one meta statically diagnosed tumor to tyrosine kinase inhibitor. (Author) 9 refs

  2. Herpes simplex virus infection in pregnancy and in neonate: status of art of epidemiology, diagnosis, therapy and prevention

    Directory of Open Access Journals (Sweden)

    2009-04-01

    Full Text Available Abstract Herpes simplex virus (HSV infection is one of the most common viral sexually transmitted diseases worldwide. The first time infection of the mother may lead to severe illness in pregnancy and may be associated with virus transmission from mother to foetus/newborn. Since the incidence of this sexually transmitted infection continues to rise and because the greatest incidence of herpes simplex virus infections occur in women of reproductive age, the risk of maternal transmission of the virus to the foetus or neonate has become a major health concern. On these purposes the Authors of this review looked for the medical literature and pertinent publications to define the status of art regarding the epidemiology, the diagnosis, the therapy and the prevention of HSV in pregnant women and neonate. Special emphasis is placed upon the importance of genital herpes simplex virus infection in pregnancy and on the its prevention to avoid neonatal HSV infections.

  3. Systemic and Disease-Specific Risk Factors in Vascular Dementia: Diagnosis and Prevention

    Directory of Open Access Journals (Sweden)

    Efraim Jaul

    2017-10-01

    Full Text Available In order to prevent the onset of vascular dementia (VaD in aging individuals, it is critical to detect clinically relevant vascular and systemic pathophysiological changes to signal the onset of its preceding prodromal stages. Identifying behavioral and neurobiological markers that are highly sensitive to VaD classification vs. other dementias is likely to assist in developing novel preventive treatment strategies that could delay the onset of disruptive psychomotor symptoms, decrease hospitalizations, and increase the quality of life in clinically-high-risk aging individuals. In light of empirical diagnostic and clinical findings associated with VaD pathophysiology, the current investigation will suggest a few clinically-validated biomarker measures of prodromal VaD cognitive impairments that are correlated with vascular symptomology, and VaD endophenotypes in non-demented aging people. In prodromal VaD individuals, distinguishing VaD from other dementias (e.g., Alzheimer's disease could facilitate specific early preventive interventions that significantly delay more severe cognitive deterioration or indirectly suppress the onset of dementia with vascular etiology. Importantly, the authors conclude that primary prevention strategies should examine aging individuals by employing comprehensive geriatric assessment approach, taking into account their medical history, and longitudinally noting their vascular, systemic, cognitive, behavioral, and clinical functional status. Secondary prevention strategies may include monitoring chronic medication as well as promoting programs that facilitate social interaction and every-day activities.

    Idiopathic osteoporosis mainly affects postmenopausal women. The normal trabecular volume of the lumbar vertebrae in a sample of healthy perimenopausal women was established by monoenergetic computed tomography. Early diagnosis of diminished bone mass is crucial for the identification of women at risk for involutionary osteoporosis following climacteric estrogen depletion. Body weight, endogenous levels of sex steroids, renal calcium and hydroxyproline excretions are not related to individual bone mass in the lumbar spine.

    2012-05-15

    Tuberculosis affected an estimated 8.8 million people and caused 1.4 million deaths globally in 2010, including a half-million women and at least 64 000 children. It also results in nearly 10 million cumulative orphans due to parental deaths. Moreover, it causes 6%-15% of all maternal mortality, which increases to 15%-34% if only indirect causes are considered. Increasingly, more women with tuberculosis are notified than men in settings with a high prevalence of human immunodeficiency virus (HIV), and maternal tuberculosis increases the vertical transmission of HIV. Tuberculosis prevention, diagnosis, and treatment services should be included as key interventions in the integrated management of pregnancy and child health. Tuberculosis screening using a simple clinical algorithm that relies on the absence of current cough, fever, weight loss, and night sweats should be used to identify eligible pregnant women living with HIV for isoniazid preventive therapy or for further investigation for tuberculosis disease as part of services for prevention of vertical HIV transmission. While implementing these simple, low-cost, effective interventions as part of maternal, neonatal, and child health services, the unmet basic and operational tuberculosis research needs of children, pregnant, and breastfeeding women should be addressed. National policy makers, program managers, and international stakeholders (eg, United Nations bodies, donors, and implementers) working on maternal, neonatal, and child health, especially in HIV-prevalent settings, should give due attention and include tuberculosis prevention, diagnosis, and treatment services as part of their core functions and address the public health impacts of tuberculosis in their programs and services.

  8. Modern aspects of diagnosis, treatment and prevention of obesity in children

    Directory of Open Access Journals (Sweden)

    S.D. Saltanova

    2017-09-01

    Full Text Available Obesity is a topical medical and social problem. Prevalence of obesity is increasing among children. The number of children under 5 years of age with overweight and obesity in the world is 44 millions. Obesity in childhood is a risk factor for the development of severe concomitant pathologies. Childhood obesity is an important prognostic factor for obesity in adults. Measures to prevent and treat childhood obesity should be directed not only to the child, but also to the whole family. To prevent obesity, excessive calorie intake should be limited. To increase the effectiveness of preventing obesity among children, we should combine reduction of energy intake with an increased physical activity. Lifestyle modification (correction of nutrition, exercise and behavioral therapy is the main method of treating children’s obesity. Introduction of school programs that increase physical activity and optimize the nutrition improve the effectiveness of treatment for childhood obesity. In case of ineffectiveness of lifestyle modification, pharmacotherapy may be prescribed. Orlistat is a medication for the treatment of obesity in children. The effectiveness of pharmacotherapy is enhanced when it is combined with integrated programs of lifestyle modification. Bariatric surgery should be used in cases of morbid obesity or failure of non-surgical treatment. Surgical treatment leads to body mass index decrease, improvement of concomitant diseases and quality of life. Bariatric surgery also has a risk of side effects, which requires continuous monitoring of complications. For the treatment and prevention of obesity, children need a multidisciplinary approach involving different specialists.

  11. [The new concept of osteoporosis. Early diagnosis, prevention and therapy are possible today].

    Science.gov (United States)

    Hesch, R D; Harms, H; Rittinghaus, E F; Brabant, G

    1990-04-15

    A paradigma of osteoporosis pathology is discussed, at the center of which is the hormone-related disturbance of the osteoblast/osteoclast functional unit. A liberal replacement of estrogen-gestagen in post-menopausal women is advocated. Early diagnosis with the aid of quantitative computed tomography makes it possible to establish the indication for timely hormonal treatment in the future, which can result in a measureable increase in bone mass. Late therapy, that is, treatment initiated after the occurrence of fractures, has proven largely ineffective.

  12. Uveal melanoma: estimating prognosis.

    Science.gov (United States)

    Kaliki, Swathi; Shields, Carol L; Shields, Jerry A

    2015-02-01

    Uveal melanoma is the most common primary malignant tumor of the eye in adults, predominantly found in Caucasians. Local tumor control of uveal melanoma is excellent, yet this malignancy is associated with relatively high mortality secondary to metastasis. Various clinical, histopathological, cytogenetic features and gene expression features help in estimating the prognosis of uveal melanoma. The clinical features associated with poor prognosis in patients with uveal melanoma include older age at presentation, male gender, larger tumor basal diameter and thickness, ciliary body location, diffuse tumor configuration, association with ocular/oculodermal melanocytosis, extraocular tumor extension, and advanced tumor staging by American Joint Committee on Cancer classification. Histopathological features suggestive of poor prognosis include epithelioid cell type, high mitotic activity, higher values of mean diameter of ten largest nucleoli, higher microvascular density, extravascular matrix patterns, tumor-infiltrating lymphocytes, tumor-infiltrating macrophages, higher expression of insulin-like growth factor-1 receptor, and higher expression of human leukocyte antigen Class I and II. Monosomy 3, 1p loss, 6q loss, and 8q and those classified as Class II by gene expression are predictive of poor prognosis of uveal melanoma. In this review, we discuss the prognostic factors of uveal melanoma. A database search was performed on PubMed, using the terms "uvea," "iris," "ciliary body," "choroid," "melanoma," "uveal melanoma" and "prognosis," "metastasis," "genetic testing," "gene expression profiling." Relevant English language articles were extracted, reviewed, and referenced appropriately.

Histopathological features suggestive of poor prognosis include epithelioid cell type, high mitotic activity, higher values of mean diameter of ten largest nucleoli, higher microvascular density, extravascular matrix patterns, tumor-infiltrating lymphocytes, tumor-infiltrating macrophages, higher expression of insulin-like growth factor-1 receptor, and higher expression of human leukocyte antigen Class I and II. Monosomy 3, 1p loss, 6q loss, and 8q and those classified as Class II by gene expression are predictive of poor prognosis of uveal melanoma. In this review, we discuss the prognostic factors of uveal melanoma. A database search was performed on PubMed, using the terms "uvea," "iris," "ciliary body," "choroid," "melanoma," "uveal melanoma" and "prognosis," "metastasis," "genetic testing," "gene expression profiling." Relevant English language articles were extracted, reviewed, and referenced appropriately.

    2016-01-01

    Full Text Available The paper deals with a rare monogenic connective tissue disease from a group of fibrillinopathies with autosomal dominant inheritance — Beals syndrome caused by a mutation in the FBN2 gene. Attention is drawn to the high phenotypic similarity of this disease and Marfan syndrome (FBN1 gene mutation, which is associated with the almost complete identity of two proteins: fibrillin 1 and fibrillin 2.The paper describes a clinical case of a child with Beals syndrome and the typical manifestations of the disease: asthenic constitution, arachnodactyly of the hands and feet, congenital contractures of the large and small joints, chest deformity, kyphoscoliosis, talpes, and crushed ears. The investigators made a differential diagnosis with other connective tissue diseases, such as Marfan syndrome, Stickler syndrome, Ehlers–Danlos syndrome, homocystenuria, and arthrogryposis. DNA diagnosis verified the Beals syndrome in the proband. Exon 28 in the FBN2 gene showed the previously undescribed missense mutation of c.3719G>A, resulting in the amino acid substitution of cysteine for tyrosine (p.Cys1240Tyr in the structure of the protein fibrillin 2. A de novo mutation occurred. There is evidence for its pathogenicity in the development of the clinical symptoms of the disease. The problems of effective medical genetic counseling in this family are discussed.

    2017-09-01

    Full Text Available Glaucoma is a common degenerative disease affecting retinal ganglion cells (RGC and optic nerve axons, with progressive and chronic course. It is one of the most important reasons of social blindness in industrialized countries. Glaucoma can lead to the development of irreversible visual field loss, if not treated. Diagnosis may be difficult due to lack of symptoms in early stages of disease. In many cases, when patients arrive at clinical evaluation, a severe neuronal damage may have already occurred. In recent years, newer perspective in glaucoma treatment have emerged. The current research is focusing on finding newer drugs and associations or better delivery systems in order to improve the pharmacological treatment and patient compliance. Moreover, the application of various stem cell types with restorative and neuroprotective intent may be found appealing (intravitreal autologous cellular therapy. Advances are made also in terms of parasurgical treatment, characterized by various laser types and techniques. Moreover, recent research has led to the development of central and peripheral retinal rehabilitation (featuring residing cells reactivation and replacement of defective elements, as well as innovations in diagnosis through more specific and refined methods and inexpensive tests.

  18. Venous thromboses and thromboembolism in acute stroke: risk factors, diagnosis, treatment, and prevention

    Directory of Open Access Journals (Sweden)

    Andrei Viktorovich Fonyakin

    2013-01-01

    Full Text Available Stroke patients among all patients with somatic diseases are at one of the highest risks for venous thromboembolism (VTE. The proven risk factors for venous thrombosis in stroke are prolonged immobilization, elderly age, obesity, diabetes mellitus, and inherited coagulopathies. If no drug prevention is done, the course of stroke is complicated by deep vein thrombosis (DVT in 75% of the immobilized patients and pulmonary thromboembolism develops in 20%. At present there are mechanical, pharmacological, and combined DVT prevention strategies that may considerably lower the rate of pulmonary embolism. In stroke patients, the use of low-molecular-weight heparins (LMWH reduces therisk of DVT, without increasing the risk of hemorrhagic complications. Novel oral anticoagulants used to treat venous thrombosis and VTE in stroke patients are an equivalent alternative to LMWH therapy. Treatment with novel oral anticoagulants to prevent recurrent VTE is effective and safe and may be continued up to 1–2 years.

  19. Risk of breast cancer after a diagnosis of ovarian cancer in BRCA mutation carriers: Is preventive mastectomy warranted?

    Preventive breast surgery and MRI screening are offered to unaffected BRCA mutation carriers. The clinical benefit of these two modalities has not been evaluated among mutation carriers with a history of ovarian cancer. Thus, we sought to determine whether or not BRCA mutation carriers with ovarian cancer would benefit from preventive mastectomy or from MRI screening. First, the annual mortality rate for ovarian cancer patients was estimated for a cohort of 178 BRCA mutation carriers from Ontario, Canada. Next, the actuarial risk of developing breast cancer was estimated using an international registry of 509 BRCA mutation carriers with ovarian cancer. A series of simulations was conducted to evaluate the reduction in the probability of death (from all causes) associated with mastectomy and with MRI-based breast surveillance. Cox proportional hazards models were used to evaluate the impacts of mastectomy and MRI screening on breast cancer incidence as well as on all-cause mortality. Twenty (3.9%) of the 509 patients developed breast cancer within ten years following ovarian cancer diagnosis. The actuarial risk of developing breast cancer at ten years post-diagnosis, conditional on survival from ovarian cancer and other causes of mortality was 7.8%. Based on our simulation results, among all BRCA mutation-carrying patients diagnosed with stage III/IV ovarian cancer at age 50, the chance of dying before age 80 was reduced by less than 1% with MRI and by less than 2% with mastectomy. Greater improvements in survival with MRI or mastectomy were observed for women who had already survived 10years after ovarian cancer, and for women with stage I or II ovarian cancer. Among BRCA mutation-carrying ovarian cancer patients without a personal history of breast cancer, neither preventive mastectomy nor MRI screening is warranted, except for those who have survived ovarian cancer without recurrence for ten years and for those with early stage ovarian cancer.

    -year revision of the GOLD document that has implemented some of the vast knowledge about COPD accumulated over the last years. Today, GOLD recommends that spirometry is required for the clinical diagnosis of COPD in order to avoid misdiagnosis and to ensure proper evaluation of severity of airflow...... limitation. The document highlights that the assessment of the COPD patient should always include assessment of 1) symptoms, 2) severity of airflow limitation, 3) history of exacerbations, and 4) comorbidities. The first three points can be used to evaluate level of symptoms and risk of future exacerbations...... and this is done in a way that split COPD patients into 4 categories - A, B, C and D. Non-pharmacologic and pharmacologic management of COPD match this assessment in an evidence-based attempt to relieve symptoms and reduce risk of exacerbations.

    Noise induced hearing loss is a slowly developing hearing impairment, caused by occupational exposure to excessive noise levels, constitutes a lesion of the auditory analyzer and clinically manifested as chronic bilateral sensorineural hearing loss. Currently, there is not a treatment that provide a cure of sensorineural hearing loss. Regular, individually tailored treatment should be directed to the pathogenic mechanisms and specific clinical symptoms of hearing loss, as well as the prevention of complications. We recommend using non-drug therapies that can improve blood flow in labyrinth, tissue and cellular metabolism.

  7. Ascaris lumbricoides: challenges in diagnosis, treatment and prevention strategies in a European refugee camp.

    Science.gov (United States)

    Claus, Paul-Emile; Ceuppens, Anne-Sophie; Cool, Mike; Alliet, Gudrun

    2018-02-19

     The roundworm Ascaris lumbricoides is one of the most prevalent parasites belonging to the class of the soil-transmitted helminths. Infections are most common in developing countries with a tropical climate where sanitation and hygiene are poor. However, prevalence of ascariasis in industrialized countries is increasing because of immigration and increasing number of refugees.  We report a case of ascariasis in a female patient who was admitted to our hospital after she had left the informal refugee camp of Calais in the north of France.  After colonoscopic removal of the worm and treatment with mebendazole during three days the patient's symptoms had completely resolved. Medical treatment with benzimidazole derivatives is easy and inexpensive. To prevent parasitic infections in larger populations, mass drug administration should be repeated periodically and must be implemented along with additional measures such as improvements to water, sanitation and hygiene (WASH). These WASH programs have been proven to be highly effective, but access and follow-up are expensive and very difficult to organize in refugee camps, even in wealthy, industrialized countries. Despite being an old, well-known parasitic disease, ascariasis might reappear in certain populations at risk in industrialized countries. Detection, treatment and follow-up of these patients, and the organization of preventive measures remain challenging.

    2017-04-17

    Cytomegalovirus (CMV) is the most frequent cause of congenital infection worldwide, with an estimated incidence in developing countries of 0.6-0.7% of all live births. The burden of disease related to congenital CMV in substantial, as it is the leading non-genetic cause of sensorineural hearing loss and an important cause of neurodevelopmental disabilities in children. Despite its clinical significance, congenital CMV infection often goes undetected because the majority of infected infants are asymptomatic at birth and screening programs have not been substantially implemented. Other than behavioral measures, effective interventions aimed at the prevention of maternal infection and of mother-to-child transmission are lacking. Due to a convergence of recent advances in both diagnostic and therapeutic strategies in infants with congenital CMV, though, the field likely will be changing rapidly over just the next few years. Specifically, a highly-sensitive screening test with high throughput potential has been developed, and treatment of infants symptomatically infected with congenital CMV has proven to be well-tolerated and effective in improving long-term hearing and neurodevelopmental outcomes.This review highlights the clinical importance of congenital CMV infection, the developments in laboratory diagnostics, and the benefits of antiviral therapy. It also identifies the global efforts still required in the prevention of maternal infection and in the optimization of antiviral therapy to further reduce the burden of congenital CMV disease.

    Trichotillomania is a disorder characterised by inability to control over pulling own hair from various parts of a body resulting in noticeable hair loss. Due to its long-term, progressive course, untreated trichotillomania can lead to disturbances in the functioning of patients and complications which are dangerous to life and health. Due to the ambiguous nature of the symptoms, they often remain unrecognised by clinicians. Most patients are afraid of revealing symptoms and reluctantly seek for professional help. In our opinion, it is necessary to increase the awareness of the disorder of physicians of different specialties to improve the detection, treatment efficacy and to prevent dangerous complications of trichotillomania. This paper summarises the current state of knowledge on the epidemiology, aetiology, clinical presentation, and treatment of trichotillomania. It is also an attempt to create guidelines in all cases of suspected trichotillomania - adapted to Polish conditions. It also highlights the importance of a multidisciplinary treatment as a condition of effectiveness of the therapy and prevention of relapse.

    Surgical operation in treating obesity and type 2 diabetes is popularizing rapidly in China. Correct prevention and recognition of perioperation-related operative complications is the premise of ensuring surgical safety. Familiar complications of the operation include deep venous thrombosis, pulmonary artery embolism, anastomotic bleeding, anastomotic fistula and marginal ulcer. The prevention of deep venous thrombosis is better than treatment. The concrete measures contain physical prophylaxis (graduated compression stocking and intermittent pneumatic compression leg sleeves) and drug prophylaxis (unfractionated heparin and low molecular heparin), and the treatment is mainly thrombolysis or operative thrombectomy. The treatment of pulmonary artery embolism includes remittance of pulmonary arterial hypertension, anticoagulation, thrombolysis, operative thrombectomy, interventional therapy and extracorporeal membrane oxygenation (ECMO). Hemorrhage is a rarely occurred but relatively serious complication after bariatric surgery. The primary cause of anastomotic bleeding after laparoscopic gastric bypass is incomplete hemostasis or weak laparoscopic repair. The common bleeding site in laparoscopic sleeve gastrectomy is gastric stump and close to partes pylorica, and the bleeding may be induced by malformation and weak repair technique. Patients with hemodynamic instability caused by active bleeding or excessive bleeding should timely received surgical treatment. Anastomotic fistula in gastric bypass can be divided into gastrointestinal anastomotic fistula and jejunum-jejunum anastomotic fistula. The treatment of postoperative anastomotic fistula should vary with each individual, and conservative treatment or operative treatment should be adopted. Anastomotic stenosis is mainly related to the operative techniques. Stenosis after sleeve gastrectomy often occurs in gastric angle, and the treatment methods include balloon dilatation and stent implantation, and surgical

    To estimate the utilization patterns of cancer prevention programs in women during the period 2000-2012 in Mexican women who participated in three national surveys. We analyzed data from the ENSA 2000, ENSANUT 2006 and ENSANUT 2012 that are representative of the Mexican population. Prevalences were obtained, trend tests and Poisson regression were used to determine the possibility of having more coverage. The coverage of Papanicolaou use in the last 12 months in 2012 was 45.5%, HPV testing in the last four years was 11.9% and mammography use in the past two years was 29.4% and 17.2% in women aged 50-69 years and 40-49 years, respectively. Although there was an increase in the coverage of screening programs, there should be a boost in the service quality and universal coverage.

    To determine the most adequate strategies for the prevention and treatment of the acute adverse effects of the use of antipsychotics. A clinical practice guideline was elaborated under the parameters of the Methodological Guide of the Ministerio de Salud y Protección Social to identify, synthesize and evaluate the evidence and make recommendations about the treatment and follow-up of adult patients with schizophrenia. A systematic literature search was carried out. The evidence was presented to the Guideline Developing Group and recommendations, employing the GRADE system, were produced. The non-pharmacological interventions such as nutritional counseling by a nutritionist, exercise and psychotherapy are effective in preventing weight gain with the use of antipsychotics. (Kg Weight reduction in DM of -3.05 (-4.16, -1.94)). The antipsychotic change from olanzapine to aripiprazole showed weight loss and decreased BMI (decreased weight in KG DM -3.21 (-9.03, -2.61). The use of beta blockers was ineffective in reducing akathisia induced by antipsychotic; using as outcome the 50% reduction of symptoms of akathisia comparing beta-blockers with placebo RR was 1.4 (0.59, 1.83). It is recommended to make psychotherapeutic accompaniment and nutrition management of overweight for patients with weight gain. If these alternatives are ineffective is suggested to change the antipsychotic or consider starting metformin. For the management of drug-induced akathisia it is recommended to decrease the dose of the drug and the addition of lorazepam. It is recommended using 5mg biperiden IM or trihexyphenidyl 5mg orally in case of secondary acute dystonia and for the treatment of antipsychotic-induced parkinsonism to decrease the dose of antipsychotic or consider using 2 - 4mg/day of biperiden or diphenhydramine 50mg once daily.

  20. Role of Brush Biopsy and DNA Cytometry for Prevention, Diagnosis, Therapy, and Followup Care of Oral Cancer

    Directory of Open Access Journals (Sweden)

    Alfred Böcking

    2011-01-01

    Full Text Available Late diagnosis resulting in late treatment and locoregional failure after surgery are the main causes of death in patients with oral squamous cell carcinomas (SCCs. Actually, exfoliative cytology is increasingly used for early detection of oral cancer and has been the subject of intense research over the last five years. Significant advances have been made both in relation to screening and evaluation of precursor lesions. As this noninvasive procedure is well tolerated by patients, more lesions may be screened and thus more oral cancers may be found in early, curable stages. Moreover, the additional use of DNA image cytometry is a reasonable tool for the assessment of the resection margins of SCC. DNA image cytometry could help to find the appropriate treatment option for the patients. Finally, diagnostic DNA image cytometry is an accurate method and has internationally been standardized. In conclusion, DNA image cytometry has increasing impact on the prevention, diagnostic, and therapeutical considerations in head and neck SCC.

    To study the incidence, diagnosis, prevention and treatment of peripherally inserted central catheter (PICC)-related upper extremity deep vein thrombosis (DVT) in breast cancer patients using a PICC catheter for chemotherapy. The data of the incidence, diagnosis and treatment of PICC-related upper extremity DVT in 187 breast cancer patients using a PICC catheter for chemotherapy, from August 2009 to July 2011 were retrospectively analyzed. In total 188 PICC were inserted between August 2009 and July 2011 and followed up for a total of 14 399 catheter-days (median placement, 76.6 days; range, 1 to 170 days). Four (2.1%) of 188 PICC were removed as a result of PICC-related upper extremity DVT in 14 to 112 catheter-days, at a rate of 0.28/1000 catheter-days. The use of PICCs in breast cancer patients for chemotherapy is safe and effective. However, some patients may develop catheter-related upper extremity DVT. In order to minimize complications, we should pay attention to its early symptoms and signs, as well as the timely removal of the catheter and appropriate anti-coagulant treatment. © 2012 Wiley Publishing Asia Pty Ltd.

  3. Adverse events during and after per-oral endoscopic myotomy: prevention, diagnosis, and management.

    Science.gov (United States)

    Nabi, Zaheer; Reddy, D Nageshwar; Ramchandani, Mohan

    2018-01-01

    Per-oral endoscopic myotomy (POEM) has surfaced as an effective endoscopic treatment modality for achalasia cardia (AC). Promising results in short- and mid-term follow-up studies have increased the use of POEM for the management of AC. POEM can be safely performed in an endoscopy suit, and major adverse events (AEs) are uncommon. AEs encountered during POEM or during the perioperative period principally include insufflation-related AEs, mucosal injuries, bleeding, pain, and aspiration pneumonia. Most insufflation-related AEs do not require an active intervention and therefore should not be considered as AEs in the true sense. When management of AEs is required, most intraoperative AEs can be managed at the same time without untoward consequences. Occurrences of AEs lessen after completion of the learning curve. However, experience alone does not ensure "zero" incidence of AEs, and early recognition remains essential. Postoperative AEs, like leaks, delayed bleeding, and delayed mucosal perforations, may pose special challenges for diagnosis and management. There is no standardized classification system for grading the severity of AEs associated with POEM, resulting in wide variation in their reported occurrences. Uniform reporting of AEs is not only crucial to comprehensively analyze the safety of POEM but also for comparison with other established treatment modalities like Heller's myotomy. GERD is an important long-term AE after POEM. Unlike the perioperative AEs, little is known regarding the intraoperative or patient-related factors that influence the occurrence of post-POEM GERD. Large prospective studies with long-term follow-up are required to determine the procedural factors associated with GERD after POEM. Copyright © 2018. Published by Elsevier Inc.

    2015-10-01

    Regorafenib is an orally available, small-molecule multikinase inhibitor with international marketing authorizations for use in colorectal cancer and gastrointestinal stromal tumors. In clinical trials, regorafenib showed a consistent and predictable adverse-event profile, with hand-foot skin reaction (HFSR) among the most clinically significant toxicities. This review summarizes the clinical characteristics of regorafenib-related HFSR and provides practical advice on HFSR management to enable health care professionals to recognize, pre-empt, and effectively manage the symptoms, thereby allowing patients to remain on active therapy for as long as possible. This review is based on a systematic literature search of the PubMed database (using synonyms of HFSR, regorafenib, and skin toxicities associated with targeted therapies or cytotoxic chemotherapy). However, as this search identified very few articles, the authors also use their clinical experience as oncologists and dermatologists managing patients with treatment-related HFSR to provide recommendations on recognition and management of HFSR in regorafenib-treated patients. Regorafenib-related HFSR is similar to that seen with other multikinase inhibitors (e.g. sorafenib, sunitinib, cabozantinib, axitinib, and pazopanib) but differs from the hand-foot syndrome seen with cytotoxic chemotherapies (e.g. fluoropyrimidines, anthracyclines, and taxanes). There have been no controlled trials of symptomatic management of regorafenib-related HFSR, and limited good-quality evidence from randomized clinical trials of effective interventions for HFSR associated with other targeted therapies. Recommendations on prevention and management of regorafenib-related HFSR in this review are therefore based on the expert opinion of the authors (dermatologists and oncologists with expertise in the management of treatment-related skin toxicities and oncologists involved in clinical trials of regorafenib) and tried-and-tested empirical

Design This review is based on a systematic literature search of the PubMed database (using synonyms of HFSR, regorafenib, and skin toxicities associated with targeted therapies or cytotoxic chemotherapy). However, as this search identified very few articles, the authors also use their clinical experience as oncologists and dermatologists managing patients with treatment-related HFSR to provide recommendations on recognition and management of HFSR in regorafenib-treated patients. Results Regorafenib-related HFSR is similar to that seen with other multikinase inhibitors (e.g. sorafenib, sunitinib, cabozantinib, axitinib, and pazopanib) but differs from the hand–foot syndrome seen with cytotoxic chemotherapies (e.g. fluoropyrimidines, anthracyclines, and taxanes). There have been no controlled trials of symptomatic management of regorafenib-related HFSR, and limited good-quality evidence from randomized clinical trials of effective interventions for HFSR associated with other targeted therapies. Recommendations on prevention and management of regorafenib-related HFSR in this review are therefore based on the expert opinion of the authors (dermatologists and oncologists with expertise in the management of treatment-related skin toxicities and oncologists involved in clinical trials of regorafenib) and

    Online gaming has greatly increased in popularity in recent years, and with this has come a multiplicity of problems due to excessive involvement in gaming. Gaming disorder, both online and offline, has been defined for the first time in the draft of 11th revision of the International Classification of Diseases (ICD-11). National surveys have shown prevalence rates of gaming disorder/addiction of 10%-15% among young people in several Asian countries and of 1%-10% in their counterparts in some Western countries. Several diseases related to excessive gaming are now recognized, and clinics are being established to respond to individual, family, and community concerns, but many cases remain hidden. Gaming disorder shares many features with addictions due to psychoactive substances and with gambling disorder, and functional neuroimaging shows that similar areas of the brain are activated. Governments and health agencies worldwide are seeking for the effects of online gaming to be addressed, and for preventive approaches to be developed. Central to this effort is a need to delineate the nature of the problem, which is the purpose of the definitions in the draft of ICD-11.

    A retrospective survey of the prevalence of TORCH infections among pregnant women was performed in the perinatal center, M. A. Tverye Military Sanitary Unit Nine (Perm), in June 2010 to December 2013. The survey covered 2060 women: they were all examined for cytomegalovirus, herpes simplex virus, and Toxoplasma. Antibodies to Toxoplasma gondii were detected in 28.68% (591/2060); 98.62% were found to have antibodies to herpes simplex; antibodies to cytomegalovirus were identified in 87.13% (1795/2060). Acute maternal toxoplasmosis was diagnosed by seroconversion or determination of IgM anti-Toxoplasma gondii antibodies, in the presence of a low avidity index and a four-fold increase in antibody titers, by simultaneously studying paired serum samples obtained at a 2-week interval. To confirm fetal infection, amniotic fluid PCR examination should be performed after 18 weeks' gestation. No consensus of opinion as to the principles of treatment for toxoplasmosis in pregnant women makes relevant the long-term results of antibacterial and antiprotozoal treatment cycles varying in duration and intensity. The prevention of acute toxoplasmosis in pregnant women ensures the principle of a mother's personal responsibility for infection safety of a newborn infant, which is informationally provided in health and safety fundamentals course and pregravid preparation schools.

    The purpose of this study was to determine the prevalence of burnout in chairs of academic departments of obstetrics and gynecology, identify important stressors, and develop strategies to treat and prevent burnout. We performed a cross-sectional study of 131 chairs in the United States and Puerto Rico. We used a 6-part questionnaire focusing on demographics, potential stressors, satisfaction with personal and professional life, self-efficacy, burnout as measured by the Maslach Burnout Inventory-Human Services Survey (MBI-HSS), and support from the spouse/partner and family. Statistical analyses were performed with the chi(2) test for categorical variables and t test or analysis of variance for continuous variables. Questionnaires were returned from 119 chairs, 110 men and 9 women, a response rate of 91%. Chairs had served an average of 7.2 years. They worked an average of 67.4 hours each week, spending 45% of their time in administrative duties, 31% in patient care, 15% in teaching, and 8% in research. Female chairs worked significantly more hours per week than male chairs, 76.9 versus 66.7 hours (P =.005). Chairs who had served >10 years worked significantly fewer hours each week than did those who had been chairs budget deficits, Medicare/Medicaid billing audits, loss of key faculty, union disputes, and faculty, resident, and staff dismissals. To deal with stress, chairs most often spent time with family and friends. Twenty-two percent of chairs were somewhat-very dissatisfied with their positions. The MBI-HSS revealed a high subscale score for emotional exhaustion, moderate-high for depersonalization, and high for personal accomplishment. High emotional exhaustion was observed in younger chairs, those who worked nearly 70 hours each week, and those with less spouse/partner support. Burnout was more common in new chairs. Burnout in chairs of obstetrics and gynecology is characterized by a high level of emotional exhaustion, moderate-high depersonalization, and

    The premise of disease-related phenotypes is the definition of the counterpart normality in medical sciences. Contrary to clinical practices that can be carefully planned according to clinical needs, heterogeneity and uncontrollability is the essence of humans in carrying out health studies. Full characterization of consistent phenotypes that define the general population is the basis to individual difference normalization in personalized medicine. Self-claimed normal status may not represent health because asymptomatic subjects may carry chronic diseases at their early stage, such as cancer, diabetes mellitus and atherosclerosis. Currently, treatments for non-communicable chronic diseases (NCD) are implemented after disease onset, which is a very much delayed approach from the perspective of predictive, preventive and personalized medicine (PPPM). A NCD pandemic will develop and be accompanied by increased global economic burden for healthcare systems throughout both developed and developing countries. This paper examples the characterization of the suboptimal health status (SHS) which represents a new PPPM challenge in a population with ambiguous health complaints such as general weakness, unexplained medical syndrome (UMS), chronic fatigue syndrome (CFS), myalgic encephalomyelitis (ME), post-viral fatigue syndrome (PVFS) and chronic fatigue immune dysfunction syndrome (CFIDS). We applied clinical informatic approaches and developed a questionnaire-suboptimal health status questionnaire-25 (SHSQ-25) for measuring SHS. The validity and reliability of this approach were evaluated in a small pilot study and then in a cross-sectional study of 3,405 participants in China. We found a correlation between SHS and systolic blood pressure, diastolic blood pressure, plasma glucose, total cholesterol and high-density lipoprotein (HDL) cholesterol among men, and a correlation between SHS and systolic blood pressure, diastolic blood pressure, total cholesterol, triglycerides

    The major increase in the prevalence of diabetes mellitus (DM) has led to the study of social inequalities in health-care. The aim of this study is to establish the possible existence of social inequalities in the prevention, diagnosis, treatment, control and monitoring of diabetes in Organisation for Economic Co-operation and Development (OECD) countries which have universal healthcare systems. We searched MEDLINE, EMBASE and the Cochrane Database of Systematic Reviews for all relevant articles published up to 15 December 2007. We included observational studies carried out in OECD countries with universal healthcare systems in place that investigate social inequalities in the provision of health-care to diabetes patients. Two independent reviewers carried out the critical assessment using the STROBE tool items considered most adequate for the evaluation of the methodological quality. We selected 41 articles from which we critically assessed 25 (18 cross-sectional, 6 cohorts, 1 case-control). Consistency among the article results was found regarding the existence of ethnic inequalities in treatment, metabolic control and use of healthcare services. Socioeconomic inequalities were also found in the diagnosis and control of the disease, but no evidence of any gender inequalities was found. In general, the methodological quality of the articles was moderate with insufficient information in the majority of cases to rule out bias. This review shows that even in countries with a significant level of economic development and which have universal healthcare systems in place which endeavour to provide medical care to the entire population, socioeconomic and ethnic inequalities can be identified in the provision of health-care to DM sufferers. However, higher quality and follow-up articles are needed to confirm these results. © 2010 Blackwell Publishing Ltd.

    Sri Lanka is currently in the prevention of re-introduction phase of malaria. The engagement of the private sector health care institutions in malaria surveillance is important. The purpose of the study was to determine the number of diagnostic tests carried out, the number of positive cases identified and the referral system for diagnosis in the private sector and to estimate the costs involved. This prospective study of private sector laboratories within the Colombo District of Sri Lanka was carried out over a 6-month period in 2015. The management of registered private sector laboratories was contacted individually and the purpose of the study was explained. A reporting format was developed and introduced for monthly reporting. Forty-one laboratories were eligible to be included in the study and 28 participated by reporting data on a monthly basis. Excluding blood bank samples and routine testing for foreign employment, malaria diagnostic tests were carried out on 973 individuals during the 6-month period and nine malaria cases were identified. In 2015, a total of 36 malaria cases were reported from Sri Lanka. Of these, 24 (67 %) were diagnosed in the Colombo District and 50 % of them were diagnosed in private hospitals. An equal number of cases were diagnosed from the private sector and government sector in the Colombo District in 2015. The private sector being a major contributor in the detection of imported malaria cases in the country should be actively engaged in the national malaria surveillance system.

    2014-01-01

    Syncope is a common medical problem, with a frequency between 15% and 39%. In the general population, the annual number episodes are 18.1–39.7 per 1000 patients, with similar incidence between genders. The first report of the incidence of syncope is 6.2 per 1000 person-years. However, there is a significant increase in the incidence of syncope after 70 years of age with rate annual 19.5 per thousand individuals after 80 years. It presents a recurrence rate of 35% and 29% of physical injury. Among the causes of syncope, the mediated neural reflex, known as neurocardiogenic or vasovagal syncope, is the most frequent. The others are of cardiac origin, orthostatic hypotension, carotid sinus hypersensitivity, neurological and endocrinological causes and psychiatric disorders. The diagnosis of syncope can be made by clinical method associated with the electrocardiogram in up 50% of patients. Its prognosis is determined by the underlying etiology specifically the presence and severity of cardiac disease. The annual mortality can reach between 18 and 33% if cardiac cause, and between 0 and 12% if the non-cardiac cause. Thus, it is imperative to identify its cause and risk stratification for positive impact in reducing morbidity and mortality. PMID:25538626

The annual mortality can reach between 18 and 33% if cardiac cause, and between 0 and 12% if the noncardiac cause. Thus, it is imperative to identify its cause and risk stratification for positive impact in reducing morbidity and mortality.

    To develop clinical practice guidelines (CPGs) for prevention, diagnosis, treatment and follow-up of ocular injuries caused by exposure to mustard gas. The clinical questions were designed by the guideline team. Websites and databases including National Guidelines Clearinghouse, National Institute for Clinical Excellence, Cochrane, and PubMed were searched to find related CPGs and explore possible answers to the clinical questions. Since there were no relevant CPGs in the literature, related articles in Persian and English languages were extracted. Each article along with its level of evidence was summarized. Additionally, hand search was performed by looking the reference list of each article. Consequently, recommendations were developed considering the clinical benefits and side effects of each therapeutic modality. The recommendations were re-evaluated in terms of customization criteria. All recommendations along with the related evidence were scored from 1 to 9 by experts from all medical universities of Iran. The level of agreement among the experts was evaluated by analyzing the given scores. The agreement was achieved for all recommendations. The experts suggested a number of minor modifications which were applied to the recommendations. Finally, CPGs were developed with 98 recommendations under three major domains including prevention of injury, diagnosis and management of the acute and delayed-onset mustard gas ocular injuries. Considering the lack of CPGs for the prevention, diagnosis, and management of mustard gas-induced keratitis, these recommendations would be useful to prevent the serious ocular complications of mustard gas and standardize eye care services to the affected individuals.

    Syphilis is an infectious disease caused by the bacterium Treponema pallidum. Syphilis has three clinical stages and may present various oral manifestations, mainly at the secondary stage. The disease mimics other more common oral mucosa lesions, going undiagnosed and with no proper treatment. Despite the advancements in medicine toward prevention, diagnosis, and treatment syphilis remains a public health problem worldwide. In this sense, dental surgeons should be able to identify the most common manifestations of the disease in the oral cavity, pointing to the role of this professional in prevention and diagnosis. This study describes a case series of seven patients with secondary syphilis presenting different oral manifestations. Copyright © 2016 Elsevier Editora Ltda. All rights reserved.

    , the emerging electromagnetic hypersensitivity (EHS) is more and more recognized by health authorities, disability administrators and case workers, politicians, as well as courts of law. We recommend treating EHS clinically as part of the group of chronic multisystem illnesses (CMI), but still recognizing that the underlying cause remains the environment. In the beginning, EHS symptoms occur only occasionally, but over time they may increase in frequency and severity. Common EHS symptoms include headaches, concentration difficulties, sleep problems, depression, a lack of energy, fatigue, and flu-like symptoms. A comprehensive medical history, which should include all symptoms and their occurrences in spatial and temporal terms and in the context of EMF exposures, is the key to making the diagnosis. The EMF exposure is usually assessed by EMF measurements at home and at work. Certain types of EMF exposure can be assessed by asking about common EMF sources. It is very important to take the individual susceptibility into account. The primary method of treatment should mainly focus on the prevention or reduction of EMF exposure, that is, reducing or eliminating all sources of high EMF exposure at home and at the workplace. The reduction of EMF exposure should also be extended to public spaces such as schools, hospitals, public transport, and libraries to enable persons with EHS an unhindered use (accessibility measure). If a detrimental EMF exposure is reduced sufficiently, the body has a chance to recover and EHS symptoms will be reduced or even disappear. Many examples have shown that such measures can prove effective. To increase the effectiveness of the treatment, the broad range of other environmental factors that contribute to the total body burden should also be addressed. Anything that supports homeostasis will increase a person's resilience against disease and thus against the adverse effects of EMF exposure. There is increasing evidence that EMF exposure has a

A comprehensive medical history, which should include all symptoms and their occurrences in spatial and temporal terms and in the context of EMF exposures, is the key to the diagnosis. The EMF exposure can be assessed by asking for typical sources like Wi-Fi access points, routers and clients, cordless and mobile phones and measurements at home and at work. It is very important to take the individual susceptibility into account.

If a detrimental EMF exposure is reduced sufficiently, the body has a chance to recover and EHS symptoms will be reduced or even disappear. Many examples have shown that such measures can prove effective. Also the survival rate of children with leukemia depends on ELF magnetic field exposure at home. To increase the effectiveness of the treatment, the broad range of other environmental factors that contribute to the total body burden should also be addressed. Anything that supports a balanced homeostasis will increase a person's resilience against disease and thus against the adverse effects of EMF exposure. There is increasing evidence that EMF exposure has a major impact on the oxidative and nitrosative regulation capacity in affected individuals. This concept also may explain why the level of susceptibility to EMF can change and why the number of symptoms reported in the context of EMF exposures is

    Full Text Available La nefropatía producida por el virus BK puede llevar a la pérdida del trasplante renal. El diagnóstico etiológico es importante debido a que la clínica no permite diferenciar entre nefropatía por virus BK y rechazo agudo, en donde los tratamientos de estas dos entidades son diametralmente opuestos. El desarrollo reciente de métodos moleculares muy sensibles y específicos como PCR y PCR en tiempo real para virus BK permiten un diagnóstico de certeza en forma rápida y cuantificar la carga viral presente. El diagnóstico de nefropatía por virus BK se realiza por inmunohistoquímica en una biopsia renal, pero dada la naturaleza multifocal de las lesiones, la sensibilidad no siempre es del 100%. Los nuevos métodos de PCR para detectar virus BK en sangre y orina contribuyen al diagnóstico de nefropatía de una manera más normatizada y menos invasiva. Más aún, la cuantificación del virus BK en sangre por PCR en tiempo real, ha demostrado ser útil en el diagnóstico y monitoreo de esta enfermedad. En este trabajo se presenta el caso de una paciente transplantada renal con nefropatía por virus BK y el desarrollo de un método de PCR en tiempo real para la detección de virus BK en sangre y orina. Esta nueva metodología confirmó el diagnóstico de nefropatía por virus BK lo que permitió un cambio en el esquema de inmunosupresión y la instauración de un tratamiento que pudo ser monitorizado utilizando la carga viral.BK virus nephropathy may lead to kidney transplant failure. BK infection and acute rejection are clinically undistinguishable, therefore diagnosis of these entities is critical to establish the correct treatment.

    Polyhydramnios is defined as a pathological increase of amniotic fluid volume in pregnancy and is associated with increased perinatal morbidity and mortality. Common causes of polyhydramnios include gestational diabetes, fetal anomalies with disturbed fetal swallowing of amniotic fluid, fetal infections and other, rarer causes. The diagnosis is obtained by ultrasound. The prognosis of polyhydramnios depends on its cause and severity. Typical symptoms of polyhydramnios include maternal dyspnea, preterm labor, premature rupture of membranes (PPROM), abnormal fetal presentation, cord prolapse and postpartum hemorrhage. Due to its common etiology with gestational diabetes, polyhydramnios is often associated with fetal macrosomia. To prevent the above complications, there are two methods of prenatal treatment: amnioreduction and pharmacological treatment with non-steroidal anti-inflammatory drugs (NSAIDs). However, prenatal administration of NSAIDs to reduce amniotic fluid volumes has not been approved in Germany. In addition to conventional management, experimental therapies which would alter fetal diuresis are being considered.

    Early diagnosis of HIV is important for the prognosis of individual patients, because antiretroviral treatment can be started at the appropriate time, and for public health, because transmission can be prevented. Data were collected from 767 HIV patients who were diagnosed in Sweden during 2003-2010 and were infected in Sweden or born in Sweden and infected abroad. A recent infection testing algorithm (RITA) was applied to BED-EIA test results (OD-n Sweden or abroad). Early diagnosis was observed in 271 patients (35%). There was no statistically significant time trend in the yearly percentage of patients with early diagnosis in the entire study group (p = 0.836) or in subgroups. Early diagnosis was significantly more common in men who have sex men (MSM) (45%) than in heterosexuals (21%) and injecting drug users (27%) (p Sweden, which does not appear to diminish.

    The aim of this study was to analyze the influence of effective preconceptional testing for carrier status in women at risk for Duchenne and Becker muscular dystrophies (D/BMD) on the prenatal diagnosis. A retrospective analysis of 201 prenatal tests was performed in 169 Polish women at risk, in regard to time of testing for carrier status (prior to conception or during pregnancy) and carrier status of tested women, including confirmed D/BMD carriers (n = 78; 46.2%), D/BMD non-carriers - tested for germline mosaicism risk (n = 23; 13.6%), and women at risk with uncertain carrier status (n = 68; 40.2%). Only 52.7% of women were tested for D/BMD carrier status prior to conception and in these women prenatal diagnosis was carried out more frequently in the first trimester of pregnancy (64.7% vs 47.8%; P = 0.035). The results of prenatal testing in male fetuses in pregnancies of confirmed D/BMD carriers and D/BMD non-carriers - tested for germline mosaicism risk were conclusive in all cases, whereas in women with uncertain carrier status, only 60.0% of results were conclusive. Eighty-five of 103 female fetuses (82.5%) were tested prenatally and in 31.8% of them fetal carrier status was confirmed. Carrier status testing in women prior to conception has a positive impact on the frequency of first-trimester prenatal diagnosis and known D/BMD carrier status on the effectiveness of prenatal diagnosis. Due to the low percentage of women tested effectively prior to conception, carrier status testing in the families at risk should be propagated (including possibility of prenatal diagnosis of female fetuses). © 2017 Japan Society of Obstetrics and Gynecology.

    Cancers constitute a significant public health problem in Nigeria. Breast, cervix and prostate cancers are leading causes of cancer-related deaths. Changing diets, lifestyles, HIV/AIDS and macro-structural factors contribute to cancer morbidity and mortality. Poor health information linking cancer risk to individual behaviors, environmental pollutants and structural barriers undermine prevention/control efforts. Studies suggest increasing health literacy and empowering individuals to take preventive action will improve outcomes and mitigate impact on a weak health system. We obtained qualitative data from 80 men, women, and young adults in 11 focus groups to assess beliefs, risk-perceptions, preventive behaviors and perceptions of barriers and facilitators to cancer control in Ibadan, Nigeria and conducted thematic analysis. Participants demonstrated awareness of cancers and mentioned several risk factors related to individual behaviors and the environment. Nonetheless, myths and misconceptions as well as micro, meso and macro level barriers impede prevention and control efforts. Developing and implementing comprehensive context-relevant health literacy interventions in community settings are urgently needed.Copyright © 2016 John Wiley & Sons, Ltd.

The period of time since HIV diagnosis should therefore be taken into account when initiating IPT. Our results also suggest that smokers and alcohol drinkers should be identified and targeted for adherence interventions when implementing IPT on a wider scale.

    To evaluate whether anthropometric parameters add to PSA measurements in middle-aged men for risk assessment of prostate cancer (PCa) diagnosis and death. After adjusting for PSA, both BMI and weight were significantly associated with an increased risk of PCa death with the odds of a death corresponding to a 10 kg/m2 or 10 kg increase being 1.58 (95% CI 1.10, 2.28; p = 0.013) and 1.14 (95% CI 1.02, 1.26; p = 0.016) times greater, respectively. AUCs did not meaningfully increase with the addition of weight or BMI to prediction models including PSA. In 1974 to 1986, 22,444 Swedish men aged 44 to 50 enrolled in Malmö Preventive Project, Sweden, and provided blood samples and anthropometric data. Rates of PSA screening in the cohort were very low. Documentation of PCa diagnosis and disease-specific death up to 2014 was retrieved through national registries. Among men with anthropometric measurements available at baseline, a total of 1692 men diagnosed with PCa were matched to 4190 controls, and 464 men who died of disease were matched to 1390 controls. Multivariable conditional logistic regression was used to determine whether diagnosis or death from PCa were associated with weight and body mass index (BMI) at adulthood after adjusting for PSA. Men with higher BMI and weight at early middle age have an increased risk of PCa diagnosis and death after adjusting for PSA. However, in a multi-variable numerical statistical model, BMI and weight do not importantly improve the predictive accuracy of PSA. Risk-stratification of screening should be based on PSA without reference to anthropometrics.

    2011-11-01

    Breast cancer is the most common cancer in women. Body weight and nutrition are known to play an important role in its pathogenesis. The question thus arises whether lifestyle factors might influence the prognosis of breast cancer, potentially offering new approaches for secondary prevention. We selectively searched the Medline database for all studies and meta-analyses on this topic that were published from 1966 to June 2010. We evaluated the cohort studies, interventional trials, and meta-analyses with respect to three target variables: tumor recurrence, tumor-specific mortality, and overall mortality. A high body-mass index (BMI) at the time of diagnosis of breast cancer is associated with higher overall mortality, as is weight gain at later times. A low-fat diet rich in fruit, vegetables, and fiber seems to be weakly associated with a better prognosis. On other hand, there is no evidence for any benefit from micronutrients, supplements, or antioxidant foods. Alcohol consumption does not affect the outcome in breast cancer. Two intervention trials of reduced fat intake showed no effect on survival, but the target of the intervention was not met in either trial. The intervention trials yielded negative results. Nevertheless, in view of the methodological difficulties in this area of research and the overall life situation of women with breast cancer, the authors recommend a health-promoting lifestyle with avoidance of overweight and a low-fat diet rich in fruit, vegetables, and fiber.

    Hepatitis C virus (HCV) infection is a major public health problem recognised by the UK National Strategy that proposes that a care pathway for assessment, diagnosis, and treatment be established in all prisons, integrated within managed clinical networks. A prison sentence provides the opportunity to focus on traditionally hard to reach patients. To evaluate the prevalence of HCV infection in a UK prison cluster and to assess the effectiveness of a prison outreach service for hepatitis C. Male prisoners. A nurse specialist led clinic within a cluster of adult prisons was established, offering health education on hepatitis C, advice on harm minimisation, and HCV testing. Infected prisoners were offered access to a care pathway leading to treatment. Outcome measures were uptake of the service, and diagnosis and treatment of hepatitis C. A total of 8.5% of 1618 prisoners accepted testing: 30% had active infection with HCV. Most were ineligible for treatment due to psychiatric illness or did not receive treatment for logistic reasons. Injecting drug use was the major risk factor in all cases. Only 7% of HCV polymerase chain amplification positive inmates received treatment in prison. There is a large pool of HCV infected prisoners at risk of complications, constituting a source of infection during their sentence and after discharge. A prison outreach clinic and care pathway was perceived as effective in delivering health education, reducing the burden on prison and hospital services. It provided an opportunity for intervention but had a limited effect in eradicating HCV in prisoners and it remains unclear how this might be achieved.

    Full Text Available Knowledge of anthracycline antibiotics’ (AAs pathogenesis and main risk factors allowed to develop various methods of prevention and early detection of cardiotoxicity as well as to create several guidelines on decreasing the risk of its development. Traditional AAs are a crucial option in treatment of metastatic breast cancer including their repeated prescription. However, their application is significantly limited by various manifestations of toxicity, especially cumulative cardiotoxicity. The most promising is use of pegylated liposomal pharmaceutical formulations of AAs. Among these formulations, pegylated liposomal doxorubicin almost fully lacks anthracycline cardiotoxicity because due to its unique formulation it accumulates almost exclusively in tumor tissue.

    Osteoporosis is a frequent disease in many populations. The hallmark is fragility fractures, which are harbingers of future fractures, disability, mortality and cost on society. The occurrence increases with age, low vitamin D level and smoking. Smoking rates are high, vitamin D is low and life expectancy is rising steeply in Greenland, as is the need for focus on osteoporosis. We report a case that uses a simple and readily available tool to diagnose osteoporosis at the hospital in Sisimiut, a town of 5000 inhabitants on the west coast of Greenland. A 51-year-old Inuit woman was seen due to lower back pain. No trauma could be recalled. Laboratory results showed a low vitamin D level and normal S-calcium, S-phosphate, S-parathyroid hormone, S-thyrotropin, erythrocyte sedimentation rate, S-creatinine and hemoglobin. The lateral chest radiograph demonstrated a reduction of anterior height of the seventh and ninth thoracic vertebral bodies of 50% and 40% respectively. Chest radiographs are frequently done in the towns along the vast coastline of Greenland, the world's largest island. They are transferred to the hospital in the capital city Nuuk using existing tele-technology, and specialist evaluations are given in electronic records available at the coastal hospitals. Effective therapies for osteoporosis are available and the identification of vertebral fractures that merit treatment may prevent future fractures, morbidity and mortality. Fragility fractures are frequent in old age and the steep rise in life expectancy and in the number of old people in Greenland emphasize the need for a focus on management of osteoporosis. Geography provides a diagnostic challenge to rural and remote areas that can be overcome by the use of lateral chest radiographs as it relies on facilities readily available. Clinical risk assessment tools with high specificity may support further osteoporosis risk prediction in remote Arctic societies.

    Full Text Available BACKGROUND: Xeroderma pigmentosum group G (XPG plays a critical role in preventing cells from oxidative DNA damage. This study aimed to investigate XPG protein expression in different gastric tissues and in patients with diverse prognoses, thus providing insights into its role in the development, progression and prognosis of gastric cancer (GC. METHODS: A total of 176 GC, 131 adjacent non-tumour tissues, 53 atrophic gastritis (AG and 49 superficial gastritis (SG samples were included. Immunohistochemical staining was used to detect XPG protein expression. RESULTS: XPG expression was significantly higher in GC tissues compared with adjacent non-tumour tissues. In the progressive disease sequence SG→AG→GC, XPG expression was significantly higher in AG and GC compared with SG. Analysis of clinicopathological parameters and survival in GC patients demonstrated a significant association between XPG expression level and depth of tumour invasion, macroscopic type, Lauren's classification, smoking, Helicobacter pylori infection and family history. Cox multivariate survival analysis indicated that patients with positive XPG expression had significantly longer overall survival (P = 0.020, HR = 0.394, 95%CI 0.179-0.866, especially in aged younger than 60 years (P = 0.027, HR = 0.361, 95%CI 0.147-0.888 and male patients (P = 0.002, HR = 0.209, 95%CI 0.077-0.571. CONCLUSIONS: This study demonstrated that XPG protein expression was related to the development, progression and prognosis of GC, and might thus serve as a potential biomarker for its diagnosis and prognosis.

    Abstract Background and objective: Idiopathic pulmonary fibrosis (IPF) has a poor prognosis in general; however, it is heterogeneous to detect relative biomarkers for predicting the disease progression. Serum biomarkers can be conveniently collected to detect and help to differentially diagnose IPF and predict IPF prognosis. This meta-analysis aimed to evaluate the use of serum surfactant proteins A and D (SP-A and SP-D) for differential diagnosis and prognosis of IPF. Methods: Relevant artic...

    HIV pre-exposure prophylaxis (PrEP) is becoming a pivotal strategy for HIV prevention. Understanding the impact of risk factors for HIV transmission to identify those at highest risk would favour the implementation of PrEP, currently limited by costs. In this service evaluation, we estimated the incidence of bacterial STIs in men who have sex with men (MSM) diagnosed with early syphilis attending a London sexual health clinic according to their HIV status. In addition, we estimated the incidence of HIV infection in HIV-negative MSM, following a diagnosis of early syphilis. We undertook a retrospective case note review of all MSM patients diagnosed with early syphilis between January and June 2014. A number of sexual health screens and diagnoses of chlamydia, gonorrhoea and HIV were prospectively analysed following the syphilis diagnosis. 206 MSM were diagnosed with early syphilis. 110 (53%) were HIV-negative at baseline, 96 (47%) were HIV-positive. Only age (37 vs 32 years, p=0.0005) was significantly different according to HIV status of MSM at baseline. In HIV-negative versus HIV-positive MSM, incidence of rectal chlamydia infection at follow-up was 27 cases vs 50/100 person-years of follow-up (PYFU) (p=0.0039), 33 vs 66/100 PYFU (p=0.0044) for rectal gonorrhoea and 10 vs 26/100 PYFU (p=0.0044) for syphilis reinfection, respectively. Total follow-up for 110 HIV-negative MSM was 144 person-years. HIV incidence was 8.3/100 PYFU (CI 4.2 to 14). A diagnosis of early syphilis carries a high risk of consequent HIV seroconversion and should warrant prioritised access to prevention measures such as PrEP and regular STI screening to prevent HIV transmission.

    Full Text Available Despite access to antiretroviral therapy, mortality from cryptococcal meningitis (CM is high among persons with advanced HIV infection in sub-Saharan Africa. Cryptococcal antigen (CrAg is present several weeks to months before the onset of symptoms of meningitis and can be screened to prevent life threatening meningitis. Recently, the World Health Organisation recommended that a new rapid CrAg lateral flow ‘‘dipstick’’ assay (LFA is to be used to screen HIV-infected persons with CD4 counts of less than 100 cells/µL. In this paper, we describe two cases of cryptococcosis with differing outcomes. In the first case, the new CrAg LFA was used as part of a screen and preemptive treatment strategy to prevent CM. In the second case, our patient had no access to the CrAg LFA and subsequently developed life threatening meningitis. To the best of our knowledge, this is the first case report of cryptococcosis diagnosed using this novel assay.

    Prospective cohort study. To report the clinical course of patients with MRI-confirmed lumbar disc herniation-related radicular noncentralizing pain who received transforaminal epidural steroid injections (TESIs) and mechanical diagnosis and therapy (MDT). Noncentralizing symptoms in patients with lumbar disc herniation are associated with poor outcome. Commonly used treatments for these patients include TESIs and MDT. No study has evaluated the outcome of combining both strategies. Consecutive candidates for herniated lumbar disc surgery with noncentralizing chronic pain were eligible. Patients received TESIs followed by MDT. The primary outcomes were pain severity in the leg, disability (Roland-Morris Disability Questionnaire for Sciatica), and global perceived effect (GPE). Outcomes were measured at baseline, discharge, and 12 months. Linear mixed-models and McNemar's tests were used to analyze outcome data. Sixty-nine patients receive TESIs. After TESIs, symptoms were resolved completely in 11 patients (16%). In these patients, symptom resolution was maintained at 12 months. A second subgroup of 32 patients (46%) reported significantly less pain after TESIs and showed centralization with MDT reassessment (significant reductions in leg pain and disability [P TESIs but still showed noncentralization with MDT reassessment (significant reductions in leg pain and disability [P TESIs and received an operative intervention. The results indicate that a course of TESIs followed by MDT may be able to avoid surgery in a substantial proportion of candidates for herniated lumbar disc surgery. Wiley Periodicals, Inc.

    Low back pain (LBP) is a common pain syndrome in athletes, responsible for 28% of missed training days/year. Psychosocial factors contribute to chronic pain development. This study aims to investigate the transferability of psychosocial screening tools developed in the general population to athletes and to define athlete-specific thresholds. Data from a prospective multicentre study on LBP were collected at baseline and 1-year follow-up (n=52 athletes, n=289 recreational athletes and n=246 non-athletes). Pain was assessed using the Chronic Pain Grade questionnaire. The psychosocial Risk Stratification Index (RSI) was used to obtain prognostic information regarding the risk of chronic LBP (CLBP). Individual psychosocial risk profile was gained with the Risk Prevention Index - Social (RPI-S). Differences between groups were calculated using general linear models and planned contrasts. Discrimination thresholds for athletes were defined with receiver operating characteristics (ROC) curves. Athletes and recreational athletes showed significantly lower psychosocial risk profiles and prognostic risk for CLBP than non-athletes. ROC curves suggested discrimination thresholds for athletes were different compared with non-athletes. Both screenings demonstrated very good sensitivity (RSI=100%; RPI-S: 75%-100%) and specificity (RSI: 76%-93%; RPI-S: 71%-93%). RSI revealed two risk classes for pain intensity (area under the curve (AUC) 0.92(95% CI 0.85 to 1.0)) and pain disability (AUC 0.88(95% CI 0.71 to 1.0)). Both screening tools can be used for athletes. Athlete-specific thresholds will improve physicians' decision making and allow stratified treatment and prevention.

    2015-09-01

    Huntington disease (HD) is a late-onset, fatal neurodegenerative disorder caused by a (CAG) triplet repeat expansion in the Huntingtin gene that enlarges during male meiosis. In 1996 in this journal, one of us (J. D. S.) presented a methodology to perform pre-implantation genetic diagnosis in families at-risk for HD without revealing the genetic status of the at-risk parent. Despite the introduction of accurate prenatal and pre-implantation genetic testing which can prevent transmission of the abnormal HD gene in the family permanently, utilization of these options is extremely low. In this article, we examine the decision-making process regarding genetic testing in families with HD and discuss the possible reasons for the low uptake among this group. © 2014 John Wiley & Sons A/S.

    1975-01-01

    Prognosis depends on establishing a relationship between the patient's state in the early stages and the ultimate outcome. Both the severity of the initial damage (including early complications) and the degree of recovery need to be defined, but practical and statistical considerations impose a limit on the number of variables which can be manipulated. Variables chosen should be those likely to be relevant, and pilot studies are more reliable than intuition in indicating which items should be included. Data chosen should be of a kind likely to be readily available for most patients and should not therefore depend on complex laboratory investigation. The most reliable indicant of initial severity appears to be the depth and duration of coma or altered consciousness, and a scale has been devised for measuring these. Measures of outcome should include separate assessment of mental and physical disability as well as the overall social consequence of the brain damage. Prognosis should be expressed as the probability (mathematically expressed) that a patient will reach certain defined outcome categories, five of which are recognized in the present study. Predictions should begin only after initial resuscitative measures are complete (say six hours after ictus); they need not be limited to the early stages but can include estimates of the degree of further improvement expected in the light of progress in the early weeks after injuries. New methods of management cannot be critically assessed unless factors influencing prognosis are reliably identified and can be matched in comparative patient groups. An estimate of prognosis is also required for the selection of patients for intensive treatment, both in the acute and in the rehabilitation stage. Without such data there is a tendency to deploy an unduly high proportion of scarce resources on patients who have little prospect of recovery; this may deny the best chance of recovery to patients with severe, but less

    Full Text Available Klippel–Trénaunay syndrome is a rare congenital condition characterised by a triad of symptoms: capillary-lymphatic-venous malformations, varicose veins and venous malformations as well as soft tissue and skeletal hypertrophy of the affected limb. In this article, we present a case of a 5-year-old boy with extensive vascular malformations of the lower limbs and the buttock region. In this case, manifestation of all three symptoms was gradual. At the age of 4 years, the patient was admitted to the Department of Imaging Diagnostics for further diagnosis, where the triad characteristic for Klippel–Trénaunay syndrome and popliteal vein agenesis were diagnosed. Currently, a multidisciplinary team takes care of the boy in the Children’s Memorial Health Institute. Early and accurate diagnosis allows for rapid prevention of complications associated with Klippel–Trénaunay syndrome and enables patient-tailored treatment.

    Submandibular gland function was tested with sup(99m)Tc-pertechnetate scan 10 days and 3-4 weeks after the onset Bell's palsy, and the results and prognoses were correlated. In the first report we divided the cases into groups A, B and C, and this time group D classified in S.S.R. was poor. Groups A and D can be differentiated by submandibular gland scan within 10 days after the onset; that is to say, the prognosis of more than half the cases can be determined in this early phase. Especially, it is noticeable that group D showing the poor prognosis is differentiated within 10 days after the onset. This method was compared with other tests of facial palsy. Four to five weeks after the onset all tests were of equal accuracy in predicting the prognosis of each group. Within 10 days after the onset, however, submandibular gland scan seems to be more useful than the other tests. (author)

    The Three Mile Island accident occurred on March 29, 1979. The decision to hold a symposium on the TMI accident aftermath was reached when it was realized that enough information had been gathered during the past 6 years to provide a fairly complete picture of the damage and of the activities required for eventual recovery. The symposium was organized into three sessions: the first dealt with a description of the accident, the second focused on the chemical aspects involved, and the third addressed the strategy and progress made toward recovery. The symposium was intended to focus on these three subjects and leave the environmental considerations to future meetings and reports. Although it might appear shortsighted to exclude the environmental impact, the exclusion was considered necessary in order to maintain the focus we sought

    Full Text Available Objective. To identify, evaluate, and synthesize evidence on the predictive power of circulating endothelial progenitor cells (EPCs in cardiovascular disease, through a systematic review of quantitative studies. Data Sources. MEDLINE was searched using keywords related to “endothelial progenitor cells” and “endothelium” and, for the different categories, respectively, “smoking”; “blood pressure”; “diabetes mellitus” or “insulin resistance”; “dyslipidemia”; “aging” or “elderly”; “angina pectoris” or “myocardial infarction”; “stroke” or “cerebrovascular disease”; “homocysteine”; “C-reactive protein”; “vitamin D”. Study Selection. Database hits were evaluated against explicit inclusion criteria. From 927 database hits, 43 quantitative studies were included. Data Syntheses. EPC count has been suggested for cardiovascular risk estimation in the clinical practice, since it is currently accepted that EPCs can work as proangiogenic support cells, maintaining their importance as regenerative/reparative potential, and also as prognostic markers. Conclusions. EPCs showed an important role in identifying cardiovascular risk conditions, and to suggest their evaluation as predictor of outcomes appears to be reasonable in different defined clinical settings. Due to their capability of proliferation, circulation, and the development of functional progeny, great interest has been directed to therapeutic use of progenitor cells in atherosclerotic diseases.

    2006-01-01

    Most patients with erythema migrans, the pathognomonic rash of Lyme disease, do not recall a deer tick bite. The rash is classically 5 to 68 cm of annular homogenous erythema (59%), central erythema (30%), central clearing (9%), or central purpura (2%). Serologic testing is not indicated for patients with erythema migrans, because initially, the result is usually negative. Successful treatment of a patient with erythema migrans can be accomplished with 20 days of oral doxycycline, amoxicillin, or cefuroxime axetil. Patients with Lyme arthritis usually present with a mildly painful swollen knee. Patients with Lyme arthritis have markedly positive serology and can usually be successfully treated with 28 days of oral doxycycline or amoxicillin. Some patients may have persistent effusion despite 4 to 8 weeks of antibiotics and may need synovectomy. Persistent effusion is not due to persistent infection. Antibiotic therapy for more than 8 weeks for patients with Lyme disease is not indicated. Chronic Lyme disease due to antibiotic resistant infection has not been demonstrated.

    Patients with chronic low back pain can present a treatment dilemma for the family physician. Low back pain is one of the most common symptoms bringing patients to physicians. Despite its high prevalence, low back pain is often difficult to treat. In most patients, the pain cannot be pinpointed at a specific anatomic lesion, and plain radiographs, computed tomographic scans and magnetic resonance imaging studies are not useful. While most people with low back pain improve regardless of the type of intervention, some evidence shows that McKenzie exercises, manipulation and injection therapy are helpful for patients who do not recover spontaneously.

    Fears of sexually harming children are fairly common among clients suffering from obsessive-compulsive disorder (OCD), yet these symptoms are largely unrecognized and frequently misdiagnosed by mental health professionals. Specifically, clients with pedophilia-themed OCD (P-OCD) experience excessive worries and distressing intrusive thoughts about being sexually attracted to, and sexually violating, children. Expressing these concerns may provoke misjudgments from uninformed mental health professionals that a client is presenting instead with pedophilic disorder. This misdiagnosis and subsequent improper interventions can then contribute to increased fear, anxiety, and in many cases, depression, in affected clients. Therefore, it is imperative that mental health professionals first possess a good understanding of this common manifestation of OCD. As such, in this article, we described obsessions and compulsions typical of P-OCD, in order to inform the reader of the distinctive differences between P-OCD and pedophilic disorder. Information about how to assess for P-OCD symptoms is then provided, followed by suggestions on how to tailor aspects of exposure and response prevention to treat this specific form of OCD.

    Endoscopic invasive procedures in 70th and 80th years leaded to decrease reoperations on biliary tree. Iatrogenic injury of the biliary tract have increased in incidence in the first decade with the introduction of laparoscopic cholecystectomy. Athough a number of factors have been identified with a high risk of injury ( and number of technical steps have been emphasized to avoid these injury, the incidence of the bile duct injury has reached at least double the rate observed with open cholecystectomy. Cholecystectomy is most frequently performed abdominal operation and the most serious complication associated with this procedure is accidental injury to the common bile duct (0.3-0.4%). This preventable technical error has tradicionally been thought to occur in one or more of three situations: 1. When the operator attempts to clip or ligate a bleeding cystic artery and also clips the common hepatic duct (Fig. 3a). 2. When too much traction has been exerted on the gallbladder so that the common bile duct has tented up into an albow, which was either tied off with ligature or clipped (Fig. 3b). 3. When anatomic anomalies were not recognized and the wrong structure is divided, for example, when the cystic duct winds anterior to the common bile duct and enters on the left side, or when the cystic duct joins the right hepatic duct rather than the junction of the common hepatic and the common bile ducts (Fig. 1, 2, 3cd). In anatomical incertain cases is discussed about cholangiography and cholecystocholangiography during laparoscopy cholecystectomy. Most patients sustained a bile duct injury are recognized in the weeks folloving laparoscopic cholecystectomy. Careful preoperative preparation should include control of sepsis by draining any bile collections or fistulas and komplete cholangiography. Long-term results are best achieved in specialized hepatobiliary centres performing biliary reconstruction with a Roux-Y hepaticojejunostomy. Success rates over 90% have been

    Any intervention involving child victims of intrafamilial abuse must take the alleged underlying motives for the abuse into account. The aim of this study is to further our understanding of intrafamilial physical abuse of children, by comparing its various aspects while considering the alleged underlying motives. A preliminary sample of 1656 cases of alleged physical abuse in the northern region of Portugal was analysed, with two main motives being identified: corporal punishment (CP) (G1 = 927) and exposure to violence between caregivers (EVC) (G2 = 308). Statistically significant differences were found between the two motives (p < 0.05) for the following variables: (1) age of the alleged victims, (2) sex of the alleged abuser, (3) risk factors affecting the alleged abuser, (4) abuser/victim relationship, (5) injury-producing mechanism, (6) time between last abuse and forensic medical examination and (7) location of injuries. Evidence-based knowledge of these differences may help in accurate diagnosis by doctors (particularly forensic physicians) and prevention of this type of violence through support strategies (including tertiary prevention strategies).

    2015-05-01

    The objective of our study was to compare treatment-based obstetrical outcomes in women with either thrombotic or obstetrical antiphospholipid syndrome (APS). This was a historical cohort study conducted between 1998 and 2009 in 23 patients who had a total of 83 pregnancies. The syndrome was diagnosed using the 2006 Sapporo criteria. Thirty-one of these 83 pregnancies were valid before the diagnosis was made. A live infant was born in 22% of them, the infant being small for gestational age in 26% of cases. The fetus died in utero in a further 26% of cases. Pregnancies were subdivided into 2 groups depending on whether the initial event leading to APS diagnosis was obstetrical or thrombotic. Treatment (aspirin and low molecular weight heparin) was based on this classification: the latter was given in a curative dose for thrombotic events, in a preventive dose for obstetrical events. No fetal loss was observed when treatment was administered according to the protocol. Nevertheless, 20% of the pregnancies with obstetrical APS were complicated by smallness for gestational age and only 38% of the infants were live births. More than 87% of the thrombotic forms treated were free of complications and led to birth of a living child. Appropriate treatment appears to improve the prognosis for pregnancies in patients with APS. These patients are nevertheless at increased risk of an obstetrical event and require close monitoring, especially in obstetrical manifestations, which appear to have a poorer prognosis. Multidisciplinary follow-up by an experienced team is essential. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Rheumatic heart disease (RHD) remains an important cause of cardiovascular morbidity and mortality globally due to weak health systems in many countries. RHD can be effectively prevented and managed; however, RHD-related interventions have not been widely adopted in countries with severe human resource constraints. Task sharing is a recognised approach to personnel shortages that could prove effective for RHD and has, anecdotally, been attempted in a few settings. We propose a systematic review and meta-analysis protocol to assess models that use non-physician workers to expand access to, and quality of, RHD-related healthcare. We will include randomised controlled trials (RCT), cluster RCTs, quasi-experimental and controlled before and after studies providing information on the effectiveness of non-physician workers in providing care for streptoccocal pharyngitis, rheumatic fever and RHD. We will search relevant electronic databases and grey literature using medical subject headings. Standardised data extraction forms will be used to collect effect sizes that will be pooled in random-effects models. We will also conduct subgroup analyses and note other important quantitative findings, such as cost reduction, and qualitative findings, such as patient satisfaction. We will also assess study quality and risk of bias and metabias. Ethics approval is not required for this systematic review of previously published literature. The results of the systematic review will be broadly disseminated via conference presentations, multidisciplinary workshops and peer-reviewed publications.

  7. Potential of the Antibody Against cis-Phosphorylated Tau in the Early Diagnosis, Treatment, and Prevention of Alzheimer Disease and Brain Injury.

    Alzheimer disease (AD) and chronic traumatic encephalopathy (CTE) share a common neuropathologic signature-neurofibrillary tangles made of phosphorylated tau-but do not have the same pathogenesis or symptoms. Although whether traumatic brain injury (TBI) could cause AD has not been established, CTE is shown to be associated with TBI. Until recently, whether and how TBI leads to tau-mediated neurodegeneration was unknown. The unique prolyl isomerase Pin1 protects against the development of tau-mediated neurodegeneration in AD by converting the phosphorylated Thr231-Pro motif in tau (ptau) from the pathogenic cis conformation to the physiologic trans conformation, thereby restoring ptau function. The recent development of antibodies able to distinguish and eliminate both conformations specifically has led to the discovery of cis-ptau as a precursor of tau-induced pathologic change and an early driver of neurodegeneration that directly links TBI to CTE and possibly to AD. Within hours of TBI in mice or neuronal stress in vitro, neurons prominently produce cis-ptau, which causes and spreads cis-ptau pathologic changes, termed cistauosis. Cistauosis eventually leads to widespread tau-mediated neurodegeneration and brain atrophy. Cistauosis is effectively blocked by the cis-ptau antibody, which targets intracellular cis-ptau for proteasome-mediated degradation and prevents extracellular cis-ptau from spreading to other neurons. Treating TBI mice with cis-ptau antibody not only blocks early cistauosis but also prevents development and spreading of tau-mediated neurodegeneration and brain atrophy and restores brain histopathologic features and functional outcomes. Thus, cistauosis is a common early disease mechanism for AD, TBI, and CTE, and cis-ptau and its antibody may be useful for early diagnosis, treatment, and prevention of these devastating diseases.

    There is limited information about long-term prognosis of ischemic stroke in young adults. Giving the potentially negative impact in physical, social, and emotional aspects of an ischemic stroke in young people, providing early accurate long-term prognostic information is very important in this clinical setting. Moreover, detection of factors associated with bad outcomes (death, recurrence, moderate-to-severe disability) help physicians in optimizing secondary prevention strategies. The prese...

    Quantifying the uncertainty in model parameters for the purpose of damage prognosis can be accomplished utilizing Bayesian inference and damage diagnosis data from sources such as non-destructive evaluation or structural health monitoring. The number of samples required to solve the Bayesian inverse problem through common sampling techniques (e.g., Markov chain Monte Carlo) renders high-fidelity finite element-based damage growth models unusable due to prohibitive computation times. However, these types of models are often the only option when attempting to model complex damage growth in real-world structures. Here, a recently developed high-fidelity crack growth model is used which, when compared to finite element-based modeling, has demonstrated reductions in computation times of three orders of magnitude through the use of surrogate models and machine learning. The model is flexible in that only the expensive computation of the crack driving forces is replaced by the surrogate models, leaving the remaining parameters accessible for uncertainty quantification. A probabilistic prognosis framework incorporating this model is developed and demonstrated for non-planar crack growth in a modified, edge-notched, aluminum tensile specimen. Predictions of remaining useful life are made over time for five updates of the damage diagnosis data, and prognostic metrics are utilized to evaluate the performance of the prognostic framework. Challenges specific to the probabilistic prognosis of non-planar fatigue crack growth are highlighted and discussed in the context of the experimental results.

    The Kidney Disease: Improving Global Outcomes (KDIGO) 2017 Clinical Practice Guideline Update for the Diagnosis, Evaluation, Prevention, and Treatment of Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD) is a selective update of the prior CKD-MBD guideline published in 2009. The guideline update and the original publication are intended to assist practitioners caring for adults with CKD and those receiving long-term dialysis. Development of the guideline update followed an explicit process of evidence review and appraisal. The approach adopted by the Work Group and the evidence review team was based on systematic reviews of relevant trials, appraisal of the quality of the evidence, and rating of the strength of recommendations according to the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach. Searches of the English-language literature were conducted through September 2015 and were supplemented with targeted searches through February 2017. Final modification of the guidelines was informed by a public review process involving numerous stakeholders, including patients, subject matter experts, and industry and national organizations. The update process resulted in the revision of 15 recommendations. This synopsis focuses primarily on recommendations for diagnosis of and testing for CKD-MBD and treatment of CKD-MBD that emphasizes decreasing phosphate levels, maintaining calcium levels, and addressing elevated parathyroid hormone levels in adults with CKD stage G3a to G5 and those receiving dialysis. Key elements include basing treatment on trends in laboratory values rather than a single abnormal result and being cautious to avoid hypercalcemia when treating secondary hyperparathyroidism.

    Due to the implementation of the International Bank for Reconstruction and Development (IBRD) loan project "Prevention, diagnosis, treatment of tuberculosis and AIDS", a "Tuberculosis" component that is an addition to the national tuberculosis control program in 15 subjects of the Russian Federation, followed up by the Central Research Institute of Tuberculosis, Russian Academy of Medical Sciences, the 2005-2008 measures stipulated by the Project have caused substantial changes in the organization of tuberculosis control: implementation of Orders Nos. 109, 50, and 690 and supervision of their implementation; modernization of the laboratories of the general medical network and antituberbulosis service (404 kits have been delivered for clinical diagnostic laboratories and 12 for bacteriological laboratories, including BACTEC 960 that has been provided in 6 areas); 91 training seminars have been held at the federal and regional levels; 1492 medical workers have been trained in the detection, diagnosis, and treatment of patients with tuberculosis; 8 manuals and guidelines have been prepared and sent to all areas. In the period 2005-2008, the tuberculosis morbidity and mortality rates in the followed-up areas reduced by 1.2 and 18.6%, respectively. The analysis of patient cohorts in 2007 and 2005 revealed that the therapeutic efficiency evaluated from sputum smear microscopy increased by 16.3%; there were reductions in the proportion of patients having ineffective chemotherapy (from 16.1 to 11.1%), patients who died from tuberculosis (from 11.6 to 9.9%), and those who interrupted therapy ahead of time (from 11.8 to 7.8%). Implementation of the IBR project has contributed to the improvement of the national strategy and the enhancement of the efficiency of tuberculosis control.

    Today we can state that in spite of a considerable number of cervical osteochondrosis studies, there is a lack of research devoted to analysis of its course. There is no correlation between initial expert evaluations of cervical osteo-chondrosis cases and further course of pathological process. Goal of the research is to develop system of course prognosis of cervical osteochondrosis taking into account environmental infuence, heredity, living conditions, psychological profle of patient’s personality. Materials and methods. Dynamics of degenerative-dystrophic changes progressing of cervical vertebrae in 236 patients was analyzed. Results. Received data demonstrated that probability of stage I changing to stage II, III and IV depended on patients’ sex, age and type of labour activity, frequent supercooling and stress. Probability of fast progression of cervical osteochondrosis (5-year cycle of stage I changing to stage III and IV was to a great extent associated with heredity, urban living, presence of endocrine system diseases, syndrome of nonspecifc dysplasia of connective tissue and low indices of quality of life. Conclusion. Proposed system allows making prognosis of morphologic changes in spinal cord, and is based on radiation methods of verifcation without taking into consideration dynamics of neurological symptomatology.

    Full Text Available Background The potential of genetic programming (GP on various fields has been attained in recent years. In bio-medical field, many researches in GP are focused on the recognition of cancerous cells and also on gene expression profiling data. In this research, the aim is to study the performance of GP on the survival prediction of a small sample size of oral cancer prognosis dataset, which is the first study in the field of oral cancer prognosis. Method GP is applied on an oral cancer dataset that contains 31 cases collected from the Malaysia Oral Cancer Database and Tissue Bank System (MOCDTBS. The feature subsets that is automatically selected through GP were noted and the influences of this subset on the results of GP were recorded. In addition, a comparison between the GP performance and that of the Support Vector Machine (SVM and logistic regression (LR are also done in order to verify the predictive capabilities of the GP. Result The result shows that GP performed the best (average accuracy of 83.87% and average AUROC of 0.8341 when the features selected are smoking, drinking, chewing, histological differentiation of SCC, and oncogene p63. In addition, based on the comparison results, we found that the GP outperformed the SVM and LR in oral cancer prognosis. Discussion Some of the features in the dataset are found to be statistically co-related. This is because the accuracy of the GP prediction drops when one of the feature in the best feature subset is excluded. Thus, GP provides an automatic feature selection function, which chooses features that are highly correlated to the prognosis of oral cancer. This makes GP an ideal prediction model for cancer clinical and genomic data that can be used to aid physicians in their decision making stage of diagnosis or prognosis.

    2017-08-01

    Thyroid hormone has important physiologic functions in nearly every organ system. The critical role of thyroid hormone in growth and in physical and neurologic development lends particular importance to the prompt diagnosis and appropriate treatment of hypothyroidism in infants and children. Congenital hypothyroidism is common and has potentially devastating neurologic consequences. While the approach to diagnosis and treatment of severe congenital hypothyroidism is well established, data continue to emerge about the genetic causes, clinical significance, and prognosis of the milder forms of congenital hypothyroidism that are increasingly being diagnosed by newborn screening. Similarly, the diagnosis and treatment of severe acquired hypothyroidism is straightforward and clearly of clinical benefit, but uncertainty remains about the optimal management of mild subclinical hypothyroidism. This review summarizes current knowledge of the causes, clinical manifestations, diagnosis, treatment, and prognosis of hypothyroidism in infants and children, with a focus on recent developments and areas of uncertainty in this field.

    Full Text Available Cerebrovasculer disease are the most frequent disease of the brain. Cerebellar infarct remains % 1.5-4.2 of these diseases. Etiological factors, lesion localization, symptoms and findings and relationship with prognosis of our patients with cerebellar infarct were investigated in our study. For this purpose, 32 patients were evaluated who were admitted to the Dicle University Medical School Department of Neurology in 1995-2001 hospitalized with the diagnosis of clinically and radiological confirmed cerebellar infarction.All of patients in the study group, 21 (%65.6 were male and 11 (%34.3 female. Age of overall patients ranged between 40 and 75 years with a mean of 57.8±10.2 years. Atherothrombotic infarct was the most frequent reason at the etiologic clinical classification. The most frequently found localization was the posterior inferior cerebellar artery infarct (%50. The leading two risk factors were hypertension (%78.1 and cigarette smoking (%50. The most common sign and symptoms were vertigo (%93.7, vomiting (%75, headache (%68.7 and cerebellar dysfunction findings (%50. The mean duration of hospitalization was 16.3±7.6 days. Overall mortality rate was found to be % 6.2. Finally, the most remarkable risk factors at cerebellar infarct patients are hypertension and atherosclerosis at etiology. We are considering that, controlling of these factors will reduce the appearance frequency of cerebellar infarcts.

    This guide aims at providing practitioners taking into care patients presenting a cutaneous cancer with recommendations based on scientific evidences or expert agreements. More precisely, the objectives are to clarify the terminology used to describe the different forms of cutaneous epidermoid carcinoma (CEC) and of their precursors (actinic keratosis, Bowen's disease), to propose a prognosis classification of CECs adapted to the previously identified prognosis factors, to optimise the diagnosis and therapy of actinic keratosis and Bowen's disease according to recent publications, and to recall the principles of a primary prevention of CECs and of their precursors, and of screening of high risk individuals. Thus, the different parts of this report address the following issues: anatomic-clinical forms and epidemiology of CECs and of their precursors, prognosis factors of CECs, means of treatment of CECs and of their precursors (medical, physical, surgical, radiation-based, and chemical treatments). Radiotherapy notably comprises external radiotherapy and interstitial brachytherapy. Indications for radiotherapy are discussed with respect to existing guides and to the clinical situation. The authors address the care of CECs and of their precursors (prevention, screening and clinical diagnosis, care of invasive CECs, keratoacanthoma treatment). They finally discuss quality criteria aimed at practice improvement, and perspectives regarding the evolution of this guide and studies to be performed

    The review summarizes new observations of key roles for circulating angiogenic factors in diagnosing, managing, and treating preeclampsia. Alterations in circulating angiogenic factors (soluble fms-like tyrosine kinase-1 and placental growth factor) in preeclampsia correlate with the diagnosis and adverse outcomes, particularly when the disease presents prematurely (preeclampsia and its complications from other disorders that present with similar clinical profiles. A ratio of soluble fms-like tyrosine kinase-1/placental growth factor greater than 85 appears ideal as the cut-off for both diagnosis and prognosis. There is also evidence that modulating these factors has therapeutic effects, suggesting a future role for angiogenic factors in treatment and prevention of preeclampsia. Circulating angiogenic biomarkers help in diagnostic and prognostic profiling of preeclampsia and may facilitate better management of these patients.

    An increase in the incidence of breast cancer in women aged breast cancer in women of childbearing age has significantly improved, they are often concerned whether subsequent pregnancy will alter their risk of disease recurrence. In the modern era, the prognosis of pregnancy-associated breast cancer is comparable to non-pregnancy-associated breast cancer and women can bear children after breast cancer treatment without compromising their survival. Therefore, they should not be discouraged from becoming pregnant, and currently the usual waiting time of at least 2 years after the diagnosis of breast cancer is recommended. However, a small, nonsignificant adverse effect of pregnancy on breast carcinoma prognosis among women who conceive within 12 months of breast cancer diagnosis and a higher risk of relapse in women younger than 35 up to 5 years of the diagnosis may be found. Fortunately, for women with localized disease, earlier conception up to six months after completing their treatment seems unlikely to reduce their survival. Ongoing and future prospective studies evaluating the risks associated with pregnancy in young breast cancer survivors are required.

    BACKGROUND We previously reported that both intraprostatic inflammation and SNPs in genes involved in the immune response are associated with prostate cancer risk and disease grade. In the present study, we evaluated the association between these SNPs and intraprostatic inflammation in men without a prostate cancer diagnosis. METHODS Included in this cross-sectional study were 205 white controls from a case-control study nested in the placebo arm of the Prostate Cancer Prevention Trial. We analyzed inflammation data from the review of H&E-stained prostate tissue sections from biopsies performed per protocol at the end of the trial irrespective of clinical indication, and data for 16 SNPs in key genes involved in the immune response (IL1β, IL2, IL4, IL6, IL8, IL10, IL12(p40), IFNG, MSR1, RNASEL, TLR4, TNFA; 7 tagSNPs in IL10). Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI) for the association between carrying at least one minor allele and having at least one biopsy core (of a mean of 3 reviewed) with inflammation. RESULTS None of the SNPs evaluated was statistically significantly associated with having at least one core with inflammation. However, possible inverse associations were present for carrying the minor allele of rs2069762 (G) in IL2 (OR=0.51, 95% CI 0.25–1.02); carrying two copies of the minor allele of rs1800871 (T) of IL10 (OR=0.29, 95% CI 0.08–1.00); and carrying the minor allele of rs486907 (A) in RNASEL (OR=0.52, 95% CI 0.26–1.06). After creating a genetic risk score from the 3 SNPs possibly associated with inflammation, the odds of inflammation increased with increasing number of risk alleles (P-trend=0.008). CONCLUSION While our findings do not generally support a cross-sectional link between individual SNPs in key genes involved in the immune response and intraprostatic inflammation in men without a prostate cancer diagnosis, they do suggest that some of these variants when in combination may be

    Full Text Available Ampullary tumors mainly manifest as obstructive jaundice and ampullary mass in clinical practice and are difficult to be identified in early stage due to a complex structure of the anatomical site, a deep location, and hidden symptoms. Sometimes a qualitative diagnosis cannot be made. Based on the experience in the treatment of ampullary tumors for many years in our center, this article summarizes the features of ampullary tumors from the aspects of clinical manifestations, diagnosis, treatment, and prognosis, especially the issues regarding imaging evaluation of ampullary tumors, selection of surgical procedure, and prognosis. An early diagnosis is the key to the treatment of ampullary tumors, and early identification and treatment of lesions have great impacts on patients′ prognosis. Accurate preoperative imaging evaluation, a professional diagnosis and treatment team, accurate preoperative and intraoperative pathological analysis, and implementation of reasonable therapeutic strategy are the key to patients′ recovery.

    Full Text Available Background and objective: Pulmonary embolism (PE is a common disease with variable symptoms and high overall mortality. The clinical relevance of the extent of PE is still debatable, and the role of anticoagulation in patients with subsegmental involvement has been contested. Our objective is to describe the clinical details of patients with PE in our hospital and to analyze their prognosis based on the extent of the disease. Materials and methods: Retrospective study of 313 patients diagnosed with PE by chest computed tomography (CT scan at the Hospital Complex of Pontevedra in Spain for six years. Predictors of mortality were determined by multivariate analysis. Results: Women accounted for 56% of patients, and patient median age was 70 years (interquartile range 53–78 years. Subsegmental PE accounted for 7% of all cases; these patients were younger and had lower comorbidity; they reported chest pain more often, performed better in blood gas analysis and none of them had proximal deep vein thrombosis (DVT. Patients with subsegmental PE had a higher survival rate. Factors independently associated with mortality were cancer diagnosis and higher comorbidity. Conclusions: Patients with subsegmental PE clinically differ from those with more proximal PE. Underlying diseases have more influence on the prognosis than the extent of the disease. Resumo: Contexto e objectivo: A embolia pulmonar (PE é uma doença comum com sintomas variáveis e uma elevada taxa de mortalidade global.

Despite the recent decline in incidence, it continues to be the deadliest form of skin cancer in children and adolescents. Pediatric melanoma presents differently from adult melanoma; thus, the traditional asymmetry, border irregularity, color variegation, diameter >6 mm, and evolution (ABCDE criteria have been modified to include features unique to pediatric melanoma (amelanotic, bleeding/bump, color uniformity, de novo/any diameter, evolution of mole. Surgical and medical management of pediatric melanoma continues to derive guidelines from adult melanoma treatment. However, more drug trials are being conducted to determine the specific impact of drug combinations on pediatric patients. Alongside medical and surgical treatment, prevention is a central component of battling the incidence, as ultraviolet (UV-related mutations play a central role in the vast majority of pediatric melanoma cases. Aggressive prevention measures targeting sun safety and tanning bed usage have shown positive sun-safety behavior trends, as well as the potential to decrease melanomas that manifest later in life. As research into the field of pediatric melanoma continues to expand, a prevention paradigm needs to continue on a community-wide level. Keywords: melanoma, pediatric, adolescent, childhood

    .Since morbidity, mortality and socioeconomic costs from Chronic Obstructive Pulmonary Disease (COPD are widely increasing, a group of respiratory medicine specialists was summoned by the AAMR to update basic knowledge on COPD and to issue recommendations for its prevention, diagnosis and treatment. The authors review the definition of COPD together with current knowledge on pathophysiology. Clinical presentation, functional evaluation and imaging are summarized. Early diagnosis through pulmonary function tests -mainly spirometry- and the role of smoking cessation are stressed. Smoking cessation strategies are described as well as pharmacological and non-pharmacological treatment. Long acting bronchodilators are considered the first pharmacological option for treatment due to its effectiveness and patient compliance. Inhaled corticosteroids are indicated in combination with long-acting bronchodilators in patients who present persistent airway obstruction associated with frequent exacerbations since they reduce their number although further studies are needed to confirm their cost/benefit. Annual influenza vaccination is recommended in all patients. In the non-pharmacological section, surgery for emphysema is suggested in very specific cases. Respiratory rehabilitation is a useful tool for patients with daily activities limitation. Long-term oxygen therapy at home improves survival in patients with severe chronic hypoxemia. Non-invasive home ventilation in chronic patients has limited indications in specific subgroups. Acute exacerbations should be aggressively treated with bronchodilators, oxygen, antibiotics, corticosteroids and eventually mechanical ventilation, as invasive as not invasive respiratory support. The importance of public education as well as of individual patients and their families is deemed essential in the prevention and treatment of the disease.

    Despite improvement in HIV prevention of mother-to-child transmission (PMTCT), there are still over 1,500 African infants newly infected daily. PMTCT elimination requires antiretroviral therapy (ART) throughout pregnancy and breastfeeding periods, while early infant diagnosis (EID) of HIV implies early treatment for those infected. Our study aimed at assessing the utility of EID program data in evaluating the implementation of PMTCT program in Cameroon, and in identifying the efficacy of existing PMTCT interventions and breastfeeding options on the events of HIV vertical transmission. A study was conducted from 2010-2011 using PMTCT data from EID sites of six regions of Cameroon. PMTCT ARV regimens, breastfeeding options, and the child's HIV DNA-polymerase chain reaction (PCR) results were recorded. Statistical analyses were performed using Mann Whitney U and Fisher exact tests, with pvertical transmission, against 31.3% (284/906) among mother-child pairs without exposure to any PMTCT intervention; pvertical transmission was recorded versus 19.9% (48/241) for mother-child pairs without intervention; pTransmission rates were similar across infant age range [2.7% (10/376) for age ≤6 weeks, versus 2.5% (43/1807) for age >6 weeks-6 months]. Interestingly, babies aged 6 weeks receiving FF showed a significantly lower transmission rate (3.2%, 9/277) as compared to their counterparts with EBF (7.7%, 12/156); pHIV MTCT may be achievable through access to ARV (option B+) and adequate infant feeding option (especially FF) in Cameroon. EID programme is therefore an effective routine approach for PMTCT programme evaluation in resource-limited settings.

  16. Quantifying prognosis with risk predictions.

    Science.gov (United States)

    Pace, Nathan L; Eberhart, Leopold H J; Kranke, Peter R

    2012-01-01

    Prognosis is a forecast, based on present observations in a patient, of their probable outcome from disease, surgery and so on. Research methods for the development of risk probabilities may not be familiar to some anaesthesiologists. We briefly describe methods for identifying risk factors and risk scores. A probability prediction rule assigns a risk probability to a patient for the occurrence of a specific event. Probability reflects the continuum between absolute certainty (Pi = 1) and certified impossibility (Pi = 0). Biomarkers and clinical covariates that modify risk are known as risk factors. The Pi as modified by risk factors can be estimated by identifying the risk factors and their weighting; these are usually obtained by stepwise logistic regression. The accuracy of probabilistic predictors can be separated into the concepts of 'overall performance', 'discrimination' and 'calibration'. Overall performance is the mathematical distance between predictions and outcomes. Discrimination is the ability of the predictor to rank order observations with different outcomes. Calibration is the correctness of prediction probabilities on an absolute scale. Statistical methods include the Brier score, coefficient of determination (Nagelkerke R2), C-statistic and regression calibration. External validation is the comparison of the actual outcomes to the predicted outcomes in a new and independent patient sample. External validation uses the statistical methods of overall performance, discrimination and calibration and is uniformly recommended before acceptance of the prediction model. Evidence from randomised controlled clinical trials should be obtained to show the effectiveness of risk scores for altering patient management and patient outcomes.

    CT of 74 patients with cerebral infarction (M : F = 42 : 32, 61 +- 12 y.o.) was investigated and a relationship between the prognosis and CT findings was analysed. CT scan was done parallel to the orbitomeatal line with 10 mm thickness, using the EMI 1010 scanner (160 x 160 matrix). In all cases CT was performed within a week from onset. Low density area was measured by planimeter on X-ray film picture. The ratio of minimum lateral ventricular transverse width to diameter of the cerebrum in 3B image was called the cerebroventricular index (CVI). Cortical atrophy was classified into four classes by visual observation. Prognosis was judged by ADL one month after onset and the ADL was classified into five degrees. Cases with larger low density area in the middle cerebral artery area showed poorer prognosis (p < 0.001). The prognosis tended to be poor if low density area was more than 20 cm/sup 2/. In the perforating artery area, no correlation was observed between size of low density area and prognosis. All cases low density area in posterior portion of the posterior limb of the internal capsule had poor prognosis. Cases with no definite low density area had rather poor prognosis compared to cases with definite low density area in the perforating artery area. The lesion in the former cases might be in either the posterior limb of the internal capsule or the brainstem. Anatomical diagnosis and prognosis of cases with no low density area should, therefore, be carefully judged. Prognosis tended to be poor in cases with CVI over 20% (p < 0.025). Although cases under 60 years old had poor ADL on admission, ADL after one month improved significantly (p < 0.025).

    Genital melanoma is a rare pathology. We present the experience of two comprehensive cancer centers in Lyon (France) in the management of genital melanoma in order to identify prognostic factors and optimal treatments. Between April 1992 and Mars 2014, 16 patients with a primary genital melanoma were referred to our department. Nine patients presented a vaginal melanoma, six vulvar melanomas and only one cervical melanoma. The median dimension of the lesion was 33.7 mm (5-100 mm). The AJCC stage ranged from IB to IIIC. 12 cases were the classic dark-blue flat melanoma and the other 4 cases were an atypical amelanotic tumor. Wide local surgery was performed in nine patients. A radical surgery was performed in six patients. In the large cervical melanoma, radiotherapy was performed as first-line treatment. In all the patients regional lymph node staging was performed. Adjuvant treatment was realized in nine patients. Two patients are alive without recurrence. Only one patient was lost to the first follow-up. The other 13 patients experienced a rapid recurrence. The median disease-free survival and the median overall survival were 11.8 months (2-49 m) and of 30.4 m (11-144 m), respectively. The disease-free survival and overall survival could be linked to a clinical presentation (Breslow thickness and morphology of lesion) associated to the early diagnosis. In our small series, the most important prognosis factor remains the tumor thickness. These rare lesions should be treated in experienced centers in order to improve their prognostic.

    Choroidal melanoma is the most common primary intraocular malignant tumor. We present the case of a 62 year old patient who was diagnosed with intraocular tumor in his right eye, for about three years. Regarding the fact that the patient refused any kind of treatment during this period, we just had the opportunity to monitor this case. Finally, the diagnosis was choroidal melanoma, confirmed by the histopathological exam.

    Full Text Available Breast cancer continues to be a disease with tremendous public health significance. Primary prevention of breast cancer is still not available, so efforts to promote early detection continue to be the major focus in fighting breast cancer. Since early detection is associated with decreased mortality, one would think that it is important to minimize delays in detection and diagnosis. There are two major types of delay. Patient delay is delay in seeking medical attention after self-discovering a potential breast cancer symptom. System delay is delay within the health care system in getting appointments, scheduling diagnostic tests, receiving a definitive diagnosis, and initiating therapy. Earlier studies of the consequences of delay on prognosis tended to show that increased delay is associated with more advanced stage cancers at diagnosis, thus resulting in poorer chances for survival. More recent studies have had mixed results, with some studies showing increased survival with longer delays. One hypothesis is that diagnostic difficulties could perhaps account for this survival paradox. A rapidly growing lump may suggest cancer to both doctors and patients, while a slow growing lump or other symptom could be less obvious to them. If this is the case, then the shorter delays would be seen with the more aggressive tumors for which the prognosis is worse leading to reduced survival. It seems logical that a tumor that is more advanced at diagnosis would lead to shorter survival; but the several counter-intuitive studies in this review show that it is dangerous to make assumptions.

    Prolactinoma is a rare pituitary adenoma secreting prolactin. Studies on diagnostics, treatment, and prognosis in pediatric prolactinoma patients are rare. We analyzed clinical presentation, response to treatment, and prognosis of 27 pediatric prolactinoma patients (10 m/17 f. based on patients' records. Tumors included 6 microadenomas (tumor volume: median 0.2 cm 3 , range 0.01-0.4 cm 3 ; serum prolactin at diagnosis: median 101 ng/ml, range 33-177 ng/ml), 15 macroadenomas (volume: median 3.3 cm 3 , range 0.4-25.8 cm 3 ; prolactin: median 890 ng/ml, range 87-8624), and 3 giant adenomas (volume: median 44.5 cm 3 , range 38.6-93.5 cm 3 ; prolactin: median 4720 ng/ml, range 317-10,400); data for 3 patients were not available. Dopamine agonist treatment (n = 22) was safe and effective, leading to reductions in tumor size (p effective and safe. Overall survival and functional capacity as a measure of quality of survival were not impaired, indicating an optimistic prognosis. Surgery should be considered only in emergency situations of threatened visual function, not presenting a fast response to dopamine agonist treatment. Severe side effects of medication and lack of efficacy should be considered as contraindications. What is Known: • In pediatric prolactinoma-a very rare pediatric neuroendocrinological disease-gender-related differences in terms of clinical presentation at initial diagnosis are known. • Due to the rareness of the disease, reports on long-term outcome and prognosis after childhood-onset prolactinoma based on prospective follow-up are not published. What is New: • Dopamine agonist treatment is efficient and safe for tumor volume reduction in pediatric prolactinoma and surgical interventions are recommended only for decompression of the optic chiasm in case of threat to vision. In case of inefficient response to medication, side effects or parental refuse, alternative therapeutic options should be considered. • Quality of life in

    Computerized tomographies (CT) were repeatedly scanned on 70 patients with cerebral infarction in the middle cerebral artery. Low density area (LDA) was measured with HounFsfield's Unit (HU) and studied on the progressive changes. Classification of LDA was attempted and studied on correlation with mass effect, contrast enhancement, angiographical findings, clinical symptoms and prognosis. It was considered that important points of diagnosis of cerebral infarction were timing of examination of CT and determination of LDA with HUF. It was also thought that CT classification of LDA was usefull to estimate prognosis of the patients with cerebral infarction. (author)

    To describe the clinical course and prognosis of ocular syphilis in patients infected with HIV-1 in the antiretroviral therapy (ART) era. We conducted a single-centre retrospective chart review of ocular syphilis in patients infected with HIV-1 diagnosed between August 1997 and July 2015. The prognosis of best-corrected visual acuity (BCVA) was analysed. The study subjects were 30 eyes of 20 men who had sex with men (MSM) (median age, 41). Loss of vision and posterior uveitis were the most common ocular clinical features (43%) and location of inflammation at presentation (50%), respectively. The median baseline BCVA was 0.4 (IQR 0.2-1.2), including three eyes with hand motion. BCVA≤0.4 at diagnosis was significantly associated with posterior uveitis or panuveitis (p=0.044). Seventy-five per cent were treated with intravenous benzylpenicillin and 53% were diagnosed with neurosyphilis. After treatment (median follow-up: 21 months), BCVA improved in 89% of the eyes, including all eyes with hand motion, to a median BCVA of 1.2 (IQR 0.8-1.2). Kaplan-Meier analysis showed that >28 days of ocular symptoms before diagnosis was the only factor associated with poor prognosis of BCVA. Three patients (15%) developed recurrence after treatment. The prognosis of BCVA in HIV-infected patients with ocular syphilis in the ART era was favourable after proper treatment. Having >28 days of ocular symptoms before diagnosis was associated with poor prognosis. Changes in visual acuity in HIV-infected MSM should prompt an immediate assessment for ocular syphilis as delays in diagnosis and therapy can lead to irreversible visual loss.

    Skeletal muscle channelopathies are rare disorders of muscle membrane excitability. Their episodic nature may result in diagnostic difficulty and delays in diagnosis. Advances in diagnostic clinical electrophysiology combined with DNA-based diagnosis have improved diagnostic accuracy and efficiency. Ascribing pathogenic status to identified genetic variants in muscle channel genes may be complex and functional analysis, including molecular expression, may help with this. Accurate clinical and genetic diagnosis enables genetic counselling, advice regarding prognosis and aids treatment selection. An approach to accurate and efficient diagnosis is outlined. The importance of detailed clinical evaluation including careful history, examination and family history is emphasised. The role of specialised electrodiagnostics combined with DNA testing and molecular expression is considered. New potential biomarkers including muscle MRI using MRC Centre protocols are discussed. A combined diagnostic approach using careful clinical assessment, specialised neurophysiology and DNA testing will now achieve a clear diagnosis in most patients with muscle channelopathies. An accurate diagnosis enables genetic counselling and provides information regarding prognosis and treatment selection. Genetic analysis often identifies new variants of uncertain significance. In this situation, functional expression studies as part of a diagnostic service will enable determination of pathogenic status of novel genetic variants.

    Full Text Available The objective of this article is to perform a critical analysis and guide veterinarians in the management of canine Leishmaniosis. A systematic literature review was performed between 2005 and 2014 including scientific papers which take into account experiences and reports of: pathogenesis, diagnosis, clinical presentation, treatment, vaccination, prevention and control strategies. We discuss the different aspects of VL management and aspects that should be taken into account depending on the country, after a patient is suspected or confirmed as positive, including the possibility of euthanasia. We describe the different clinical manifestations of the disease, diagnosis, signs and treatment of canine leishmaniosis. Canine leishmaniosis is present in different parts of the country, therefore it must be considered as a possible differential diagnosis in the veterinary clinic, in patients with dermatological and systemic signs that are compatible with various diseases. In Colombia, the patients diagnosed with cutaneous leishmaniasis could be treated and have a favorable prognosis, whereas in canines with diagnosis of visceral leishmaniasis euthanasia should be considered because of the public health implications.

    Treatment-related immunosuppression in organ transplant recipients has been linked to increased incidence and risk of progression for several malignancies. Using a population-based cancer cohort, we evaluated whether organ transplantation was associated with worse prognosis in elderly patients with non-small cell lung cancer (NSCLC). Using the Surveillance, Epidemiology, and End Results Registry linked to Medicare claims, we identified 597 patients aged 65 years or older with NSCLC who had received organ transplants (kidney, liver, heart, or lung) before cancer diagnosis. These cases were compared to 114,410 untransplanted NSCLC patients. We compared overall survival (OS) by transplant status using Kaplan-Meier methods and Cox regression. To account for an increased risk of non-lung cancer death (competing risks) in transplant recipients, we used conditional probability function (CPF) analyses. Multiple CPF regression was used to evaluate lung cancer prognosis in organ transplant recipients while adjusting for confounders. Transplant recipients presented with earlier stage lung cancer (P = 0.002) and were more likely to have squamous cell carcinoma (P = 0.02). Cox regression analyses showed that having received a non-lung organ transplant was associated with poorer OS (P transplantation was associated with no difference in prognosis. After accounting for competing risks of death using CPF regression, no differences in cancer-specific survival were noted between non-lung transplant recipients and nontransplant patients. Non-lung solid organ transplant recipients who developed NSCLC had worse OS than nontransplant recipients due to competing risks of death. Lung cancer-specific survival analyses suggest that NSCLC tumor behavior may be similar in these 2 groups.

    To assess breast cancer (BC) risk after Hodgkin's lymphoma (HL) and compare characteristics, risk of second BC, and prognosis of patients with these BCs with patients with first primary BC. We considered all 9,620 women with HL recorded in the Surveillance, Epidemiology and End Results dataset in 1973-2007. We calculated age-period standardized incidence ratios of BC. We compared patient, tumor, and treatment characteristics, risk of second BC, and prognosis between patients with BC after HL (n = 316) and patients with other BCs occurring during the same period (n = 450,413) using logistic regression and Cox models adjusted for confounders. HL patients had a 2.4-fold higher risk for developing BC (95% confidence interval [CI], 2.2-2.7) than the general population. Age at HL diagnosis and radiation therapy influenced this risk. Compared with first primary BCs, BCs after HL were diagnosed at a younger age, at an earlier stage, were less frequently hormone receptor positive, were located more frequently in external quadrants, and were less frequently treated using radiotherapy. These patients had a higher risk (adjusted hazard ratio [HR], 2.85; 95% CI, 1.79-4.53) for developing a second BC and had a higher BC mortality risk (adjusted HR, 1.36; 95% CI, 1.05-1.76). The higher mortality risk was only partly explained by the higher occurrence rate of a second BC. HL survivors have a higher risk for developing BC, their BCs are more aggressive, they have a higher risk for a second BC occurrence, and they have a poorer prognosis. Guidelines of care should be adapted to decrease the impact of BC in these high-risk patients.

    Ovarian cancer (OvCa) is among the most common types of cancer and is the leading cause of death from gynecological malignancies in western countries. Cancer biomarkers have a potential for improving the management of OvCa patients at every point from screening and detection, diagnosis, prognosis, follow up, response to therapy and outcome. The literature search has indicated a number of candidate biomarkers have recently emerged that could facilitate the molecular definition of OvCa, providing information about prognosis and predicting response to therapy. These potentially promising biomarkers include immune cells and their products, tumor-derived exosomes, nucleic acids and epigenetic biomarkers. Expert commentary: Although most of the biomarkers available today require prospective validation, the development of noninvasive liquid biopsy-based monitoring promises to improve their utility for evaluations of prognosis, response to therapy and outcome in OvCa.

    1982-01-01

    A brief survey is given of the present knowledge of the problems, based on literary data. Pyrophosphate myocardial scan is an important examination in establishing the diagnosis of acute myocardial infarction and some other myocardial diseases. Apart from this, it is of great importance in determining the prognosis. In the early phase of the disease, an apparently worse prognosis is found in patients with extensive lesion, and in those with an infarction intensively cumulating the radiopharmaceutical. In a certain number of infarctions, scintigraphic examination is positive over several months; usually the radiopharmaceutical disappears within two weeks. Patients with long-persisting positivity have a markedly worse prognosis. On the basis of early and late heart scan, it is thus possible to estimate the future fate of patients w+th ischemic heart disease. Large and long-persisting lesions serve as a warning for the physician. (author)

    Diffuse alveolar hemorrhage (DAH) of unknown cause has been characterized as idiopathic pulmonary hemosiderosis (IPH). IPH is a rare disease, which has a high prevalence in children and shows a poor prognosis. However, in adults, since there are few reports about collective cases, the details remain to be determined. Between January 2003 and June 2008, consecutive adult patients strictly defined as unknown cause DAH by chest images, fiberoptic bronchoscopy, autoantibody testing, and exclusion of systemic disease were enrolled. We investigated the clinical characterization and course of the enrolled patients. Nine patients were included. All patients were middle-aged men (56.1 ± 4.2 year-old) with sudden onset. They did not present with anemia (the hemoglobin level was 13.9 ± 0.5 g/dL) despite the quantity of bleeding. In bronchoalveolar-lavage fluid analysis, the cell count was increased (7.6 ± 1.6×10(5) cells/mL) with neutorophilia (33.3 ± 13.3%). The illness resolved within 2 weeks with or without corticosteroid therapy. All of the patients were alive without recurrence during the follow-up period (45.2 ± 6.2 months) after diagnosis. Adult IPH patients showed good prognosis. However, the present patients are clinically slightly different from the previously characterized IPH.
