    AIDS associated malignancies (ARL) is a major complication associated with AIDS patients upon immunosuppression.Chronically immunocompromised patients have a markedly increased risk of developing lymphoproliferative disease. In the era of potent antiretrovirals therapy (ARV), the malignant complications due to HIV- 1 infection have decreased in developed nations where ARV is administered, but still poses a major problem in developing countries where HIV- 1incidence is high and ARV is still not yet widely available. Even in ARV treated individuals there is a concern that the prolonged survival of many HIV- 1 carriers is likely to eventually result in an increased number of malignancies diagnosed.Malignancies that were found to have high incidence in HIV-infected individuals are Kaposi's sarcoma (KS), Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL). The incidence of NHL has increased nearly 200 fold in HIV-positive patients, and accounts for a greater percentage of AIDS defining illness in the US and Europe since the advent of HAART therapy. These AIDS related lymphomas are distinct from their counterparts seen in HIV- 1 seronegative patients.For example nearly half of all cases of ARL are associated with the presence of a gamma herpesvirus, Epstein Barr virus (EBV) or human herpesvirus-8 (HHV-8)/Kaposi's sarcoma associated herpesvirus (KSHV). The pathogenesis of ARLs is complex. B-cell proliferation driven by chronic antigenemia resulting in the induction of polyclonal and ultimately monoclonal lymphoproliferation may occur in the setting of severe immunosuppression.

    1994-09-01

    Neuroleptic malignant syndrome (NMS) has been recently described following therapy with non strictly neuroleptic drugs that alter dopaminergic function, such as sulpiride and metoclopramide, and might occur more easily in patients with functional or organic brain disorders. We observed an AIDS patient who suffered from NMS following treatment with clotiapine for insomnia and agitation. Two months later, he presented with a similar syndrome following antiemetic treatment with alizapride. On both occasions, the symptoms completely regressed after the administration of dopaminergic and muscle relaxant drugs. The patient died of pneumonia one month after the last episode. The present paper describes the clinical and pathological findings.

  10. Working memory and intelligibility of hearing-aid processed speech.

    Previous work suggested that individuals with low working memory capacity may be at a disadvantage in adverse listening environments, including situations with background noise or substantial modification of the acoustic signal. This study explored the relationship between patient factors (including working memory capacity) and intelligibility and quality of modified speech for older individuals with sensorineural hearing loss. The modification was created using a combination of hearing aid processing [wide-dynamic range compression (WDRC) and frequency compression (FC)] applied to sentences in multitalker babble. The extent of signal modification was quantified via an envelope fidelity index. We also explored the contribution of components of working memory by including measures of processing speed and executive function. We hypothesized that listeners with low working memory capacity would perform more poorly than those with high working memory capacity across all situations, and would also be differentially affected by high amounts of signal modification. Results showed a significant effect of working memory capacity for speech intelligibility, and an interaction between working memory, amount of hearing loss and signal modification. Signal modification was the major predictor of quality ratings. These data add to the literature on hearing-aid processing and working memory by suggesting that the working memory-intelligibility effects may be related to aggregate signal fidelity, rather than to the specific signal manipulation. They also suggest that for individuals with low working memory capacity, sensorineural loss may be most appropriately addressed with WDRC and/or FC parameters that maintain the fidelity of the signal envelope.

    Annie J Sasco

    relatively small number of studies warrant further epidemiological investigations, taking into account other known risk factors for these tumors. CONCLUSION: Studies conducted in sub-Saharan Africa show that HIV infection is not only strongly associated with AIDS-classifying cancers but also provided some evidence of association for other neoplasia. African countries need now to implement well designed population-based studies in order to better describe the spectrum of AIDS-associated malignancies and the most effective strategies for their prevention, screening and treatment.

  13. AIDS in Africa. ILO launches campaign on HIV / AIDS in the world of work.

    Science.gov (United States)

    1999-01-01

    This article presents the proceedings of the regional workshop on HIV/AIDS and its social and labor impact in Africa conducted by the International Labor Organization (ILO) in Pretoria. According to the Pretoria report, HIV/AIDS had become a human tragedy in Africa. It affects the health and development of the region and threatens the social and economic growth of almost all sub-Saharan African countries. It is considered to be the single most important impediment to social progress to many countries in Africa. Thus, the primary goal of the ILO, which is promoting opportunities for women and men to obtain decent and productive work in conditions of freedom, equity, security and human dignity, is threatened by the HIV/AIDS pandemic. However, several activities have taken place in response to the need for the prevention and control of the disease. In addition, the report calls for efforts to create an enabling environment for people living with the disease involving governments, employers' and workers' organizations. It noted that the ILO could provide assistance in the adoption of laws and regulations to protect the rights of these people with regards to the access of health insurance, employment, education, as well as labor administration, productivity and the informal sector.

    In the past decade, extensive research on dielectric properties of biological tissues led to characterization of dielectric property discrepancy between the malignant and healthy tissues. Such discrepancy enabled the development of microwave therapeutic and diagnostic technologies. Traditionally, dielectric property measurements of biological tissues is performed with the well-known contact probe (open-ended coaxial probe) technique. However, the technique suffers from limited accuracy and low loss resolution for permittivity and conductivity measurements, respectively. Therefore, despite the inherent dielectric property discrepancy, a rigorous measurement routine with open-ended coaxial probes is required for accurate differentiation of malignant and healthy tissues. In this paper, we propose to eliminate the need for multiple measurements with open-ended coaxial probe for malignant and healthy tissue differentiation by applying support vector machine (SVM) classification algorithm to the dielectric measurement data. To do so, first, in vivo malignant and healthy rat liver tissue dielectric property measurements are collected with open-ended coaxial probe technique between 500 MHz to 6 GHz. Cole-Cole functions are fitted to the measured dielectric properties and measurement data is verified with the literature. Malign tissue classification is realized by applying SVM to the open-ended coaxial probe measurements where as high as 99.2% accuracy (F1 Score) is obtained.

    Full Text Available Fungal malignant otitis externa (FMOE is a serious and potentially life-threatening condition that is challenging to manage. Diagnosis is often delayed due to the low sensitivity of aural swabs and many antifungal drugs have significant side effects. We present a case of FMOE, where formal tissue sampling revealed the diagnosis and the patient was successfully treated with voriconazole, in addition to an up to date review of the current literature. We would recommend tissue biopsy of the external auditory canal in all patients with suspected FMOE in addition to routine microbiology swabs.

    Background Computer-aided diagnosis (CAD) of lung cancer is the subject of many current researches. Statistical methods and artificial neural networks have been applied to more quantitatively characterize solitary pulmonary nodules (SPNs). In this study, we developed a CAD scheme based on an artificial neural network to distinguish malignant from benign SPNs on thin-section computed tomography (CT) images, and investigated how the CAD scheme can help radiologists with different levels of experience make diagnostic decisions.Methods Two hundred thin-section CT images of SPNs with proven diagnoses (135 small peripheral lung cancers and 65 benign nodules) were analyzed. Three clinical features and nine CT signs of each case were studied by radiologists,and the indices of qualitative diagnosis were quantified. One hundred and forty nodules were selected randomly to form training samples, on which the neural network model was built. The remaining 60 nodules, forming test samples, were presented to 9 radiologists with 3-20 years of clinical experience, accompanied by standard reference images. The radiologists were asked to determine whether a nodule was malignant or benign first without and then with CAD output.Diagnostic performance was evaluated by receiver operating characteristic (ROC) analysis.Results CAD outputs on test samples had higher agreement with pathological diagnoses (Kappa=0.841, P<0.001).Compared with diagnostic results without CAD output, the average area under the ROC curve with CAD output was 0.96(P<0.001) for junior radiologists, 0.94 (P=0.014) for secondary radiologists and 0.96 (P=0.221) for senior radiologists,respectively. The differences in diagnostic performance with CAD output among the three levels of radiologists were not statistically significant (P=0.584, 0.920 and 0.707, respectively).Conclusions This CAD scheme based on an artificial neural network could improve diagnostic performance and assist radiologists in distinguishing

    An automated computer-aided diagnosis system is developed to classify benign and malignant thyroid nodules using multi-stained fine needle aspiration biopsy (FNAB) cytological images. In the first phase, the image segmentation is performed to remove the background staining information and retain the appropriate foreground cell objects in cytological images using mathematical morphology and watershed transform segmentation methods. Subsequently, statistical features are extracted using two-level discrete wavelet transform (DWT) decomposition, gray level co-occurrence matrix (GLCM) and Gabor filter based methods. The classifiers k-nearest neighbor (k-NN), Elman neural network (ENN) and support vector machine (SVM) are tested for classifying benign and malignant thyroid nodules. The combination of watershed segmentation, GLCM features and k-NN classifier results a lowest diagnostic accuracy of 60 %. The highest diagnostic accuracy of 93.33 % is achieved by ENN classifier trained with the statistical features extracted by Gabor filter bank from the images segmented by morphology and watershed transform segmentation methods. It is also observed that SVM classifier results its highest diagnostic accuracy of 90 % for DWT and Gabor filter based features along with morphology and watershed transform segmentation methods. The experimental results suggest that the developed system with multi-stained thyroid FNAB images would be useful for identifying thyroid cancer irrespective of staining protocol used.

  4. Health effects of working in pulp and paper mills: malignant diseases.

    Torén, K; Persson, B; Wingren, G

    1996-02-01

    This paper reviews the available literature regarding the work environment in pulp and paper mills and the risk for malignant diseases. An increased risk for lung cancer among pulp and paper mill workers has been reported. Most studies are inconclusive with regard to considerations of etiologic agents. However, maintenance workers seem to be at an increased risk for lung cancer, as well as for malignant mesothelioma, indicating that this occupational group was (is) exposed to asbestos. Workers exposed to chlorine compounds also seem to run an increased risk for lung cancer. An increased risk for malignant lymphomas among pulp mill workers is a constant finding. The increased risk is observed both among sulfite and sulfate workers, indicating a common exposure. Such an exposure could be wood dust, terpenes, or preservatives present in the wood. An increased risk for leukemias has been found in many studies carried out on pulp and paper workers, but the studies do not permit any conclusions about etiologic factors. In some studies an increased risk for stomach cancer has been found. However, the socioeconomic status of the workers is strongly related to stomach cancer, and factors, such as dietary habits, have not been taken into account in any of the reviewed studies. Hence, no further conclusions can be drawn regarding etiologic agents.

    Various aspects must be anticipated in the planning of first aid in the massive orienteering contest Jukola-relay. Spreading of the event to a wide forest terrain area, beyond the reach of roads, poses a challenge for the evacuation of injured persons. The communication chains must be secured. In addition to the competition center, first aid points must be devised at various off-road points. Capable volunteers must be recruited in sufficient numbers. Establishing a temporary, health center standard emergency preparedness for approximately 50 000 people necessitates the acquisition of equipment and medicines for emergency care. Preparations must be made for the treatment of injuries and attacks of illness among the competitors, the audience and the volunteers.

  14. Aiding cities in their work on climate change adaptation

    Hamilton, P.

    2013-12-01

    Urban areas around the world are at the frontlines of climate change because of their enormous aggregate populations and because of their vulnerability to multiple climate change stressors. Half of our planet's 7.1 billion inhabitants currently reside in cities with six billion people projected to call cities home by 2050. In the U.S. and much of the rest of the world, cities are warming at twice the rate of the planet. Superimposed on urban climate changes driven by global warming are the regional effects of urban heat domes driven by large differences in land use, building materials, and vegetation between cities and their rural surroundings. In megacities - those with populations exceeding 10 million people - such as Tokyo - urban heat domes can contribute to daytime temperatures that soar to more than 11°C higher than their rural surroundings. In addition, the localized warming can alter patterns of precipitation in metropolitan regions and perhaps even influence the frequency and severity of severe weather. Municipal officials need to accelerate their efforts to prepare and implement climate change adaptation strategies but what are the institutions that can help enable this work? Informal science education centers can play vital roles because they are overwhelmingly in urban settings and because they can act as ';competent outsiders.' They are neither responsible for conducting climate change research nor accountable for implementing public policies to address climate change. They instead can play an essential role of ensuring that solid science informs the formulation of good practices and policies. It is incumbent, therefore, for informal science education centers to accelerate and enhance their abilities to help translate scientific insights into on-the-ground actions. This session will explore the potential roles of informal science education centers to advance climate change adaptation through a review of the urban climate change education initiatives

    Highly active antiretroviral therapy (HAART) for human immunodeficiency virus (HIV) infection has been widely available in industrialized countries since 1996; its widespread use determined a dramatic decline in acquired immunodeficiency syndrome (AIDS)-related mortality, and consequently, a significant decrease of AIDS-defining cancers. However the increased mean age of HIV-infected patients, prolonged exposure to environmental and lifestyle cancer risk factors, and coinfection with oncogenic viruses contributed to the emergence of other malignancies that are considered non-AIDS-defining cancers (NADCs) as a relevant fraction of morbidity and mortality among HIV-infected people twenty years after HAART introduction. The role of immunosuppression in the pathogenesis of NADCs is not well defined, and future researches should investigate the etiology of NADCs. In the last years there is a growing evidence that intensive chemotherapy regimens and radiotherapy could be safely administrated to HIV-positive patients while continuing HAART. This requires a multidisciplinary approach and a close co-operation of oncologists and HIV-physicians in order to best manage compliance of patients to treatment and to face drug-related side effects. Here we review the main epidemiological features, risk factors and clinical behavior of the more common NADCs, such as lung cancer, hepatocellular carcinoma, colorectal cancer and anal cancer, Hodgkin’s lymphoma and some cutaneous malignancies, focusing also on the current therapeutic approaches and preventive screening strategies.

    Full Text Available Abstract Background Nurses' aides (assistant nurses, the main providers of practical patient care in many countries, are doing both emotional and heavy physical work, and are exposed to frequent social encounters in their job. There is scarce knowledge, though, of how working conditions are related to psychological distress in this occupational group. The aim of this study was to identify work factors that predict the level of psychological distress in nurses' aides. Methods The sample of this prospective study comprised 5076 Norwegian nurses' aides, not on leave when they completed a mailed questionnaire in 1999. Of these, 4076 (80.3 % completed a second questionnaire 15 months later. A wide spectrum of physical, psychological, social, and organisational work factors were measured at baseline. Psychological distress (anxiety and depression was assessed at baseline and follow-up by the SCL-5, a short version of Hopkins Symptom Checklist-25. Results In a linear regression model of the level of psychological distress at follow-up, with baseline level of psychological distress, work factors, and background factors as independent variables, work factors explained 2 % and baseline psychological distress explained 34 % of the variance. Exposures to role conflicts, exposures to threats and violence, working in apartment units for the aged, and changes in the work situation between baseline and follow-up that were reported to result in less support and encouragement were positively associated with the level of psychological distress. Working in psychiatric departments, and changes in the work situation between baseline and follow-up that gave lower work pace were negatively associated with psychological distress. Conclusion The study suggests that work factors explain only a modest part of the psychological distress in nurses' aides. Exposures to role conflicts and threats and violence at work may contribute to psychological distress in nurses' aides

    Full Text Available Abstract Background In workplace health promotion, all potential resources needs to be taken into consideration, not only factors relating to the absence of injury and the physical health of the workers, but also psychological aspects. A dynamic balance between the resources of the individual employees and the demands of work is an important prerequisite. In the home care services, there is a noticeable trend towards increased psychosocial strain on employees at work. There are a high frequency of work-related musculoskeletal disorders and injuries, and a low prevalence of sustainable work ability. The aim of this research was to identify factors promoting work ability and self-efficacy in care aides and assistant nurses within home care services. Methods This study is based on cross-sectional data collected in a municipality in northern Sweden. Care aides (n = 58 and assistant nurses (n = 79 replied to a self-administered questionnaire (response rate 46%. Hierarchical multiple regression analyses were performed to assess the influence of several independent variables on self-efficacy (model 1 and work ability (model 2 for care aides and assistant nurses separately. Results Perceptions of personal safety, self-efficacy and musculoskeletal wellbeing contributed to work ability for assistant nurses (R2adj of 0.36, p 2adj of 0.29, p = 0.001. Self-efficacy was associated with the safety climate and the physical demands of the job in both professions (R2adj of 0.24, p = 0.003 for care aides, and also by sex and age for the assistant nurses (R2adj of 0.31, p Conclusions The intermediate factors contributed differently to work ability in the two professions. Self-efficacy, personal safety and musculoskeletal wellbeing were important for the assistant nurses, while the work ability of the care aides was associated with the safety climate, but also with the non-changeable factors age and seniority. All these factors are important to acknowledge in

    Computer aided design (CAD) in conjunction with digitised anthropometric manikins can be used for analysis and control of stressful work postures, one of the most frequently cited occupational risk factors of upper extremity cumulative trauma disorders. This paper describes the use of macros for manipulating manikins and workstation components and for designing the workplace. AutoCAD, a popular computer aided design software package, was used to demonstrate the feasibility of these concepts. Specifically, macros are used for drawing work equipment using parametric designs, manipulating manikins and analysing jobs. In comparing the macros to the use of primitive CAD commands, the macros not only decrease the amount of time needed to create workstation components, but they also make the task easier for the user and decrease the risk of errors. Despite the limitation of anthropometric data and manikins, CAD is an effective method for identifying postural stresses and redesigning the workstation to control the identified stresses.

Working memory can be envisioned as a limited-capacity system which is engaged when an input signal cannot be readily matched to a stored representation or template. This mismatch is expected to occur more frequently when the signal is degraded. Because working memory capacity varies among individuals, those with smaller capacity are expected to demonstrate poorer speech understanding when speech is degraded, such as in background noise. However, it is less clear whether (and how working memory should influence practical decisions, such as hearing treatment. Here, we consider the relationship between working memory capacity and response to specific hearing aid processing strategies. Three types of signal processing are considered, each of which will alter the acoustic signal: fast-acting wide-dynamic range compression, which smooths the amplitude envelope of the input signal; digital noise reduction, which may inadvertently remove speech signal components as it suppresses noise; and frequency compression, which alters the relationship between spectral peaks. For fast-acting wide-dynamic range compression, a growing body of data suggests that individuals with smaller working memory capacity may be more susceptible to such signal alterations, and may receive greater amplification benefit with low alteration processing. While the evidence for a relationship between wide-dynamic range compression and working memory appears robust, the effects of working memory on perceptual response to other forms of hearing aid signal processing are less clear cut. We conclude our review with a discussion of the opportunities (and challenges in translating information on individual working memory into clinical treatment, including clinically-feasible measures of working memory.

    Full Text Available The present study aimed to investigate the changing relationship between aided speech recognition and cognitive function during the first 6 months of hearing aid use. Twenty-seven first-time hearing aid users with symmetrical mild to moderate sensorineural hearing loss were recruited. Aided speech recognition thresholds in noise were obtained in the hearing aid fitting session as well as at 3 and 6 months postfitting. Cognitive abilities were assessed using a reading span test, which is a measure of working memory capacity, and a cognitive test battery. Results showed a significant correlation between reading span and speech reception threshold during the hearing aid fitting session. This relation was significantly weakened over the first 6 months of hearing aid use. Multiple regression analysis showed that reading span was the main predictor of speech recognition thresholds in noise when hearing aids were first fitted, but that the pure-tone average hearing threshold was the main predictor 6 months later. One way of explaining the results is that working memory capacity plays a more important role in speech recognition in noise initially rather than after 6 months of use. We propose that new hearing aid users engage working memory capacity to recognize unfamiliar processed speech signals because the phonological form of these signals cannot be automatically matched to phonological representations in long-term memory. As familiarization proceeds, the mismatch effect is alleviated, and the engagement of working memory capacity is reduced.

    In post-apartheid South Africa, there has been a significant rise in women's out-migration from rural areas and across its territorial borders for economic purposes resulting in gender reconfiguration of migration streams. Alongside, there has been a simultaneous increase in the participation of women in the labor force. However, this has mostly grown in the informal sector,1 which is often associated with low earnings and insecure working conditions. One consequence has been the increasing reliance of migrant women on survivalist activities such as informal sexual exchanges that increase their risk of contracting HIV infection. Insecure working environments also expose migrant women to sexual abuses. This article is based on the author's work in South Africa's major urban centers and examines the nature of the relationship between the increased migration of black African women in South Africa, the nature of their work, and their resultant vulnerability to HIV/AIDS.

    It is difficult to distinguish desmoplastic malignant mesothelioma (DMM) from fibrous pleuritis (FP). We investigated the utility of immunohistochemistry as a way of differentiating between DMM and FP. We examined 11 DMMs and 46 FPs with the aid of antibodies against 18 cytokeratin (CK) subtypes, calponin, caldesmon, desmin, and GLUT-1. The best sensitivity and specificity cut-off values in the receiver operating characteristic curves (ROC) for CKs 7, 8, 17, 18, and 19, and GLUT-1 were each above 60%. When cases with either DMM or FP were partitioned by the staining score associated with the best sensitivity and specificity cut-off values in ROC, the incidence of a positive expression for CKs 7, 8, 17, 18, and 19, and GLUT-1 was significantly higher in DMM than in FP. In conclusion, immunohistochemistry for CKs 7, 8, 17, 18, and 19, and GLUT-1 may be useful, alongside histological characteristics, for separating DMM from FP.

    Full Text Available Automated detection and diagnosis of small lesions in breast MRI represents a challenge for the traditional computer-aided diagnosis (CAD systems. The goal of the present research was to compare and determine the optimal feature sets describing the morphology and the enhancement kinetic features for a set of small lesions and to determine their diagnostic performance. For each of the small lesions, we extracted morphological and dynamical features describing both global and local shape, and kinetics behavior. In this paper, we compare the performance of each extracted feature set for the differential diagnosis of enhancing lesions in breast MRI. Based on several simulation results, we determined the optimal feature number and tested different classification techniques. The results suggest that the computerized analysis system based on spatiotemporal features has the potential to increase the diagnostic accuracy of MRI mammography for small lesions and can be used as a basis for computer-aided diagnosis of breast cancer with MR mammography.

    Purpose: To develop a semiautomated computer-aided diagnosis (CAD) system for thyroid cancer using two-dimensional ultrasound images that can be used to yield a second opinion in the clinic to differentiate malignant and benign lesions. Methods: A total of 118 ultrasound images that included axial and longitudinal images from patients with biopsy-confirmed malignant (n = 30) and benign (n = 29) nodules were collected. Thyroid CAD software was developed to extract quantitative features from these images based on thyroid nodule segmentation in which adaptive diffusion flow for active contours was used. Various features, including histogram, intensity differences, elliptical fit, gray-level co-occurrence matrixes, and gray-level run-length matrixes, were evaluated for each region imaged. Based on these imaging features, a support vector machine (SVM) classifier was used to differentiate benign and malignant nodules. Leave-one-out cross-validation with sequential forward feature selection was performed to evaluate the overall accuracy of this method. Additionally, analyses with contingency tables and receiver operating characteristic (ROC) curves were performed to compare the performance of CAD with visual inspection by expert radiologists based on established gold standards. Results: Most univariate features for this proposed CAD system attained accuracies that ranged from 78.0% to 83.1%. When optimal SVM parameters that were established using a grid search method with features that radiologists use for visual inspection were employed, the authors could attain rates of accuracy that ranged from 72.9% to 84.7%. Using leave-one-out cross-validation results in a multivariate analysis of various features, the highest accuracy achieved using the proposed CAD system was 98.3%, whereas visual inspection by radiologists reached 94.9% accuracy. To obtain the highest accuracies, “axial ratio” and “max probability” in axial images were most frequently included in the

    Full Text Available Este estudo pretende ampliar discussões sobre o trabalho dos agentes comunitários de saúde, na atenção primária, em relação ao HIV/AIDS. Para tal, o objetivo foi dar visibilidade para os sentidos construídos sobre HIV/AIDS em um grupo com agentes comunitários de saúde. Foi realizada uma entrevista com um grupo de quatro agentes, sendo a mesma gravada, transcrita e analisada na perspectiva do construcionismo social. A análise das narrativas informa como os diferentes sentidos atribuídos ao longo da história da epidemia se fazem presentes nas concepções e no trabalho com HIV/AIDS, a saber: o preconceito ancorado pelo discurso científico; as relações de gênero implicadas no trabalho; os valores contemporâneos atrelados à perfeição e juventude. Destaca-se que tais sentidos construídos conjuntamente na interação grupal, interpretam e constituem o fazer saúde. Assim, conclui-se que a criação de espaços para a troca dialógica entre os profissionais possibilita problematizar sentidos aparentemente cristalizados no que se refere a temática do HIV/AIDS.The present study intends to extend discussions about the community health agents work in the primary attention, concerning HIV/AIDS.

    An estimated 200,000-500,000 men, women, and children work in prostitution in the Philippines in a variety of venues, including brothels, nightclubs, pubs, massage parlors, and other legitimate entertainment establishments. Few, however, are voluntary prostitutes. Many people who work as prostitutes have been recruited from the provinces, kept in conditions similar to slavery, and forced to earn money from prostitution to pay for their transportation, board, and lodging. Many prostitutes work in urban centers and tourist resorts in the countryside. During the 1970s, then President Ferdinand Marcos promoted tourism as a major industry, effectively marketing attractive Filipinas to tourists. Sex tourism has flourished in the country ever since. Thousands of prostitutes are also located in Olongapo and Angeles, 2 cities north of Manila, from where they serve the sexual desires of US military personnel. The presence of US military personnel in the Philippines has always been associated with prostitution. The country's social hygiene centers, prostitutes in Manila and Davao, and AIDS education are briefly discussed.

    The purpose of this pilot study was to explore the impact of a certified nurse's aide (CNA)-led interdisciplinary teamwork and communication intervention on perceived quality of work environment and six-month job intentions. CNAs are frequently excluded from team communication and decision-making, which often leads to job dissatisfaction with high levels of staff turnover. Using a mixed quantitative and qualitative approach with pre- post-program design, the intervention utilized the strategy of debriefing from the national patient safety initiative, TeamSTEPPS. Inherent in the program design, entitled Long Term Care (LTC) Team Talk, was the involvement of the CNAs in the development of the intervention as an empowering process on two wings of a transitional care unit in a long-term care facility in upstate NY. CNAs' perceptions of work environment quality were measured using a Quality of Work Life (QWL) instrument. Additionally, job turnover intent within six months was assessed. Results indicated improved scores on nearly all QWL subscales anticipated to be impacted, and enhanced perceived empowerment of the CNAs on each wing albeit through somewhat different experiential processes. The program is highly portable and can potentially be implemented in a variety of long-term care settings.

  14. Myths or theories? Alternative beliefs about HIV and AIDS in South African working class communities.

    Despite three decades of public health promotion based on the scientific explanation of HIV/AIDS, alternative explanations of the disease continue to circulate. While these are seen as counter-productive to health education efforts, what is rarely analysed is their plurality and their tenacity. This article analyses the 'AIDS myths' collected by African HIV/AIDS workplace peer educators during an action research project. These beliefs about HIV/AIDS are organised, in this article, around core ideas that form the basis of 'folk' and 'lay theories' of HIV/AIDS. These constitute non-scientific explanations of HIV/AIDS, with folk theories drawing on bodies of knowledge that are independent of HIV/AIDS while lay theories are generated in response to the disease. A categorisation of alternative beliefs about HIV/AIDS is presented which comprises three folk theories - African traditional beliefs, Christian theology, and racial conspiracy - and three lay theories, all focused on avoiding HIV infection. Using this schema, the article describes how the plausibility of these alternative theories of HIV/AIDS lies not in their scientific validity, but in the robustness of the core idea at the heart of each folk or lay theory. Folk and lay theories of HIV/AIDS are also often highly palatable in that they provide hope and comfort in terms of prevention, cure, and the allocation of blame. This study argue that there is coherence and value to these alternative HIV/AIDS beliefs which should not be dismissed as ignorance, idle speculation or simple misunderstandings. A serious engagement with folk and lay theories of HIV/AIDS helps explain the continued circulation of alternative beliefs of HIV/AIDS and the slow uptake of behavioural change messages around the disease.

    The complexity of providing healthcare to people with HIV/Aids requires investment in comprehensive action and care, constituting a challenge for the multidisciplinary work teams to build an interdisciplinary practice. This study sought to analyze comprehensive healthcare in the Specialized Assistance Services for HIV/Aids (SAE-HIV/Aids) in Recife, in the State of Pernambuco, starting with the process and organization of team work. This is a case study developed in three SAE-HIV/Aids units, based on a qualitative approach using different research techniques. The results show that SAE-HIV/Aids have complied with most of the Brazilian Health Ministry recommendations in terms of basic infrastructure, though none of them had a team of appropriate size. These services have shown signs of fragmentation and difficulty in establishing a systematic intersectorial and interdisciplinary practice, with failings in ensuring the reference and counter-reference flow. It was seen that there was little appreciation of the role of the manager as team leader. The need to perceive the user as a whole was identified, as well as for the team to work in a coordinated manner in order to ensure communicative and relational activities.

Our aim was to establish the incidence of these malignancies at an ambulatory care center between 1997 and 2005. We describe 103 cases of malignancies, 73 out of them were ARM and 30 were non-ARM. There were no differences in terms of age, gender and proportion of patients on highly active antiretroviral treatment (HAART. Among those patients with ARM, simultaneous diagnosis of malignancy and HIV infection was more frequently seen (p <0.001 and the proportion of patients with AIDS was higher (p = 0.015. Among those patients with non-ARM the mean duration of HIV infection and HAART was higher (p = 0.038and 0.002 respectively; also was higher the mean CD4 count nadir (p = 0.009, and CD4 count at the time of malignancy diagnosis (p <0.001. The incidence of ARM was 18 cases/1000 patients-year in 1997 and dropped to 3.1 cases/1000 patients-year in 2005 (p = 0.001. The incidence of non-ARM was always lower than ARM, and similar in each year. In conclusion, ARM were more frequent than non-ARM, but their incidence dropped significantly because of massive use of HAART, while non-ARM remained stable. The high proportion of simultaneous diagnosis of ARM and HIV infection should enable much earlier HIV diagnosis.

    Full Text Available Abstract Background The Federal Ministry of Health of Ethiopia is implementing an ambitious and rapid scale-up of health care services for the prevention, care and treatment of HIV/AIDS in public facilities. With support from the United States President's Emergency Plan for AIDS Relief, 38 830 service providers were trained, from early 2005 until December 2007, in HIV-related topics. Anecdotal evidence suggested high attrition rates of providers, but reliable quantitative data have been limited. Methods With that funding, Jhpiego supports a Training Information Monitoring System, which stores training information for all HIV/AIDS training events supported by the same funding source. Data forms were developed to capture information on providers' working status and were given to eight partners who collected data during routine site visits on individual providers about working status; if not working at the facility, date of and reason for leaving; and source of information. Results Data were collected on 1744 providers (59% males in 53 hospitals and 45 health centres in 10 regional and administrative states. The project found that 32.6% of the providers were no longer at the site, 57.6% are still working on HIV/AIDS services at the same facility where they were trained and 10.4% are at the facility, but not providing HIV/AIDS services. Of the providers not at the facility, the two largest groups were those who had left for further study (27.6% and those who had gone to another public facility (17.6%. Of all physicians trained, 49.2% had left the facility. Regional and cadre variation was found, for example Gambella had the highest percent of providers no longer at the site (53.7% while Harari had the highest percentage of providers still working on HIV/AIDS (71.6%. Conclusion Overall, the project found that the information in the Training Information Monitoring System can be used to track the working status of trained providers. Data generated from

    This study aimed to evaluate the value of using 3-D breast MRI morphologic features to differentiate benign and malignant breast lesions. The 3-D morphological features extracted from breast MRI were used to analyze the malignant likelihood of tumor from ninety-five solid breast masses (44 benign and 51 malignant) of 82 patients. Each mass-like lesion was examined with regards to three categories of morphologic features, including texture-based gray-level co-occurrence matrix (GLCM) feature, shape, and ellipsoid fitting features. For obtaining a robust combination of features from different categories, the biserial correlation coefficient (|r(pb)|)≧0.4 was used as the feature selection criterion. Receiver operating characteristic (ROC) curve was used to evaluate performance and Student's t-test to verify the classification accuracy. The combination of the selected 3-D morphological features, including conventional compactness, radius, spiculation, surface ratio, volume covering ratio, number of inside angular regions, sum of number of inside and outside angular regions, showed an accuracy of 88.42% (84/95), sensitivity of 88.24% (45/51), and specificity of 88.64% (39/44), respectively. The AZ value was 0.8926 for these seven combined morphological features. In conclusion, 3-D MR morphological features specified by GLCM, tumor shape and ellipsoid fitting were useful for differentiating benign and malignant breast masses.

    2016-11-08

    Narratives of cultural stakeholders in marginalized sex worker spaces often do not find the traction to influence mainstream health discourse. Furthermore, such narratives are framed against the grain of the dominant cultural narrative; they are resistive texts, and they depict enactments of resistance to the normal order. This article, based on 12 weeks of field study in a sex worker community in India, foregrounds how sex workers communicatively frame and enact resistance, and hence formulate insurgent texts, along a continuum-from overt violence to covert negotiation on issues such as condom and alcohol use. Making note of these insurgent texts is crucial to understanding how meanings of health are locally made in a sex worker community as it is often that members of such marginalized communities take recourse to covert and ritualistic forms of resistance to work, to survive, and to stay free of HIV infection.

    Pleural malignancies, primary or metastatic, portend a grim prognosis. In addition to the serious oncologic implications of a pleural malignancy, these tumors can be highly symptomatic. A malignant pleural effusion can cause dyspnea, secondary to lung compression, or even tension physiology from a hydrothorax under pressure. The need to palliate these effusions is a seemingly straightforward clinical scenario, but with nuances that can result in disastrous complications for the patient if not attended to appropriately. Solid pleural malignancies can cause great pain from chest wall invasion or can cause a myriad of morbid symptoms because of the invasion of thoracic structures, such as the heart, lungs, or esophagus. This article reviews pleural malignancies, the purely palliative treatments, and the treatments that are performed with definitive (curative) intent.

    Thymidine kinase 1 (TK1) is a DNA precursor enzyme whose expression is closely correlated with cell proliferation and cell turnover. Sensitive serum TK1 activity assays have been used for monitoring and prognosis of hematological malignancies in both humans and dogs. Here we describe the development of a specific sandwich TK1-ELISA for the quantification of TK1 protein levels in sera from dogs with different malignancies. A combination of rabbit polyclonal anti-dog TK1 antibody and a mouse monoclonal anti-human TK1 antibody was used. Different concentrations of recombinant canine TK1 was used as standard. Clinical evaluation of the ELISA was done by using sera from 42 healthy dogs, 43 dogs with hematological tumors and 55 with solid tumors. An established [3H]-dThd phosphorylation assay was used to determine the TK1 activity levels in the same sera. The mean TK1 activities in dogs with hematological tumors were significantly higher than those found in healthy dogs. In agreement with earlier studies, no significant difference was observed in serum TK1 activities between healthy dogs and dogs with solid tumors. However, the mean TK1 protein levels determined by new TK1-ELISA were significantly higher not only in hematological tumors but also in solid tumors compared to healthy dogs (mean ± SD = 1.30 ± 1.16, 0.67 ± 0.55 and 0.27± 0.10 ng/mL, respectively). Moreover, TK1-ELISA had significantly higher ability to distinguish lymphoma cases from healthy based on receiver operating characteristic analyses (area under the curve, AUC, of 0.96) to that of the activity assay (AUC, 0.84). Furthermore, fluctuations in TK1 protein levels during the course of chemotherapy in dogs with lymphoma closely associated with clinical outcome. Overall, the TK1-ELISA showed significant linear correlation with the TK1 activity assay (rs = 0.6, p<0.0001). Thus, the new TK1-ELISA has sufficient sensitivity and specificity for routine clinical use in veterinary oncology.

    Full Text Available Catatonia is a syndrome characterized by mutism, immobility, negativism, stereotypy, mannerisms, echophenomena, perseveration and passive obedience. The underlying causes can be psychiatric or may be associated with general medical status or neurological diseases. Additionally catatonia has two subtypes as malignant and nonmalignant catatonia. Main symptoms of malignant catatonia are hyperthermia and autonomic symptoms such as tachycardia, tachypnea and hyperhidrosis. It is important to make the diagnosis as early as possible for an appropriate medical treatment. Clinicians should be aware of the fatal outcome of the disease.

    Full Text Available The aim of this review is to discuss current knowledge about pathophysiology and clinical, therapeutic and prophylactic approaches for malignant glaucoma. This type of glaucoma can occur after different surgical procedures. It can also occur in aphakic, phakic and pseudophakic eyes and develop spontaneously in individuals with no ocular surgical history, or associated with topical miotics. Currently, the ultrasound biomicroscopy has provided many interesting and useful findings for diagnosis and monitoring the treatment of malignant glaucoma. It occurs more often in short eyes in which pre operative measurements of the anterior chamber depth and axial length are extremely important for its prophylaxis and diagnosis.

    Background. Dentists have an ethical responsibility to provide treatment to HIV-infected patients, particularly because oral lesions are common among these patients. However, there are no official guidelines as to how to treat people living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) (PLWHA) or how to screen for potentially infectious people. Materials and Method. A descriptive cross-sectional questionnaire based study which assessed the knowledge and attitude of the faculty members towards the treatment of patients with HIV/AIDS was carried out in the Sudha Rustagi College of Dental Sciences, Faridabad, and Maulana Azad Institute of Dental Sciences, New Delhi. Results. The willingness to treat patients with HIV was found to be 86.0% among the faculty members in the present study. The majority (79%) of the faculty members thought that treating an HIV-positive patient is ethical responsibility of the dentist. There was a positive attitude (88.0%) among faculty members that routine dental care should be a part of the treatment of patients with HIV/AIDS. Conclusion. The level of knowledge regarding HIV and AIDS was acceptable in the present study. However, continuing dental education (CDE) programmes should be conducted on a regular basis for updating the knowledge level of the faculty members towards the dental treatment of patients with HIV/AIDS patients.

    Full Text Available Introduction. HIV/AIDS-related stigma occurs in the world towards people living with HIV/AIDS in a different form. Stigma among nurses in health care setting is one of the main challenges towards the prevention and management of HIV/AIDS in developing countries. It is one of the main reasons keeping patients from seeking health care service. Therefore assessing the magnitude of stigma and associated factors towards people living on HIV/AIDS among nurses is of paramount importance for the quality of nursing care as well as service utilization. Methods. An institutional based cross-sectional study was conducted in March 2013. Pretested and structured questionnaire via self-administration was used in the tool of HIV/AIDS Stigma Instrument-Nurse (HASI-N. Data were entered using EPI info version 3.5.3 and transferred to SPSS version 20 for further analysis. Descriptive statistics were conducted to summarize the sample characteristics. A backward stepwise logistic regression model was fitted and adjusted odds ratio with 95% confidence interval was calculated to identify associated factors. Results. A total of 386 nurses participated yielding a response rate of 97.2%. Nearly two-thirds (64.5% of them have shown stigma towards people living with HIV/AIDS in the health institution. Qualification level of diploma or certificate, lack of training, experiences of <06 years, low HIV patient caseload seen in the last six months, and the absence of guidelines/protocols about HIV/AIDS in their health institution were associated factors for stigma. Conclusions. The findings of this research showed high magnitude of stigma towards people living with HIV/AIDS among nurses. For stigma to be decreased nurses need to update their knowledge through training and experience sharing with senior staff. And it is crucial that the Ethiopian Ministry of Health, Amhara Regional Health Bureau, and the two hospitals work for decreasing stigma by creating educational development

    Many malignant tumors such as colorectal cancer or breast cancer cause liver metastases. The therapy strategy is dependent on the primary tumor. Laser induced Interstitial Thermotherapy (LITT), together with various other minimally invasive approaches, is a thermotherapy and could be applied in addition to surgery or as the exclusive method of treating isolated liver metastases. Major advantages of such an approach are the possibility of implementing an outpatient scheme, as well as a lower occurrence rate of complications. After a CT-controlled puncture of the metastases the therapy is monitored in the MRI by using thermosensitive sequences. Liver tissue absorbs energy from laser photons; heat caused by this effect leads to the destruction of tumorous tissue. As the amount of energy required to destroy the metastases varies greatly even with the volume of lesions being the same, the aim of this paper is to find out whether there is a relation between energy requirement and liver density as gauged by means of CT before treatment. For this purpose 168 patients with 279 liver metastases originating from different primaries who were treated with LITT between March 2006 and March 2007 were included in this study. 55.4 % of the patients were pretreated with TACE, which reduces the blood flow in the liver, thus reducing amount of energy required from laser photon treatment. Prior to every single LITT sequence liver density was gauged by puncture CT with the aid of Hounsfield units; also, the volume of the induced necrosis in the 24h MRI image and in the control MRI after 3, 6 and 12 months was measured. It was possible to calculate the actual energy consumption on the basis of number, running time and energy output of the laser employed. Check-up examinations showed a decrease of the mean necrosis-volumes, which indicates that absence of recurrence of the tumor in those spots that had been laser-treated.

    Activation-induced cytidine deaminase (AID) is the mutator enzyme in adaptive immunity. AID initiates the antibody diversification processes in activated B cells by deaminating cytosine to uracil in immunoglobulin genes. To some extent other genes are also targeted, which may lead to genome instability and B cell malignancy. Thus, it is crucial to understand its targeting and regulation mechanisms. AID is regulated at several levels including subcellular compartmentalization. However, the complex nuclear distribution and trafficking of AID has not been studied in detail previously. In this work, we examined the subnuclear localization of AID and its interaction partner CTNNBL1 and found that they associate with spliceosome-associated structures including Cajal bodies and nuclear speckles. Moreover, protein kinase A (PKA), which activates AID by phosphorylation at Ser38, is present together with AID in nuclear speckles. Importantly, we demonstrate that AID physically associates with the major spliceosome subunits (small nuclear ribonucleoproteins, snRNPs), as well as other essential splicing components, in addition to the transcription machinery. Based on our findings and the literature, we suggest a transcription-coupled splicing-associated model for AID targeting and activation. - Highlights: • AID and its interaction partner CTNNBL1 localize to Cajal bodies and nuclear speckles. • AID associates with its activating kinase PKA in nuclear speckles. • AID is linked to the splicing machinery in switching B-cells. • Our findings suggest a transcription-coupled splicing associated mechanism for AID targeting and activation.

    Until recently, Computer-Aided Medical Interventions (CAMI) and Medical Robotics have focused on rigid and non deformable anatomical structures. Nowadays, special attention is paid to soft tissues, raising complex issues due to their mobility and deformation. Mini-invasive digestive surgery was probably one of the first fields where soft tissues were handled through the development of simulators, tracking of anatomical structures and specific assistance robots. However, other clinical domains, for instance urology, are concerned. Indeed, laparoscopic surgery, new tumour destruction techniques (e.g. HIFU, radiofrequency, or cryoablation), increasingly early detection of cancer, and use of interventional and diagnostic imaging modalities, recently opened new challenges to the urologist and scientists involved in CAMI. This resulted in the last five years in a very significant increase of research and developments of computer-aided urology systems. In this paper, we propose a description of the main problems rel...

Todos recibieron profilaxis con trimetoprima-sulfametoxazol y azitromicina según la recomendación actual. Evaluamos el desarrollo de NIDS en los 6 meses posteriores al inicio de la terapia y su asociación con variables clínicas y epidemiológicas. Analizamos 235 historias clínicas: 118 mujeres (50.2% y 117 hombres (49.8%. Observamos 11 casos de NIDS: 3 formas pulmonares y 3 ganglionares de tuberculosis, 3 meningitis por Criptococcus neoformans, 1 chagoma cerebral y 1 linfoma no Hodgkin. Presentar recuento de células CD4 menor a 100 o 150 células/ml se asoció con riesgo de desarrollar NIDS. La media de células CD4 fue 73 en los pacientes que desarrollaron NIDS y 143 en los que no la desarrollaron. No hubo asociación con las otras variables analizadas. En pacientes con CD4 menor a 150 células/ml observamos un caso de chagoma cerebral entre 4 con serología reactiva para Chagas, y ninguno de toxoplasmosis cerebral entre 46 con serología reactiva para toxoplasmosis. Concluimos que la tasa de incidencia de NIDS fue del 4.7%, siendo tuberculosis en primer lugar y criptococosis en segundo las enfermedades más frecuentemente observadas.

    2009-03-01

    Recent public service announcements (PSAs) directed toward Black youth utilize various formats and appeals to stimulate a motivated cognitive process that engenders personal involvement in the HIV/AIDS issue. The Elaboration Likelihood Model (ELM) by Petty and Cacioppo argues that engagement with messages that consist of substantive content causes the audience member to critically analyze the message, which can produce awareness and attitude change. An efficient way to add emphasis to the message and seize the attention of the target audience is to insert the message into an entertainment context. Our study attempted to analyze the impact of the peripheral cue, character appeal, on audience members' attitude change in response to analyzing high- and low-involvement message content. A2 x 4 factorial design was used, with message involvement (high/low) and character appeal (White/Black and celebrity/noncelebrity) as independent variables. The findings showed that celebrity status is the salient factor, with source perception inducing attitude change as a main effect or in an interaction effect with high- and low message content.

    Almost three decades ago, we presented a model where theextracellular matrix (ECM) was postulated to influence gene expressionand tissue-specificity through the action of ECM receptors and thecytoskeleton. This hypothesis implied that ECM molecules could signal tothe nucleus and that the unit of function in higher organisms was not thecell alone, but the cell plus its microenvironment. We now know that ECMinvokes changes in tissue and organ architecture and that tissue, cell,nuclear, and chromatin structure are changed profoundly as a result ofand during malignant progression. Whereas some evidence has beengenerated for a link between ECM-induced alterations in tissuearchitecture and changes in both nuclear and chromatin organization, themanner by which these changes actively induce or repress gene expressionin normal and malignant cells is a topic in need of further attention.Here, we will discuss some key findings that may provide insights intomechanisms through which ECM could influence gene transcription and howtumor cells acquire the ability to overcome these levels ofcontrol.

    2005-01-01

    Background: Sexual transmission of HIV in China is rapidly increasing, in part driven by commercial sex work. Goal: This article examines variations in occupational control among one type of brothel-based prostitutes in China, and the relationship between the terms and content of this work and the risk of HIV/AIDS. Organizational factors, are discussed as part of the current political, economic, and social context of sex work in China. Study: The analysis is based on ethnographic observation and in-depth interviews conducted in south China in 2000 and 2001 involving 158 female prostitutes from 45 brothels in 4 red light districts. Qualitative analysis of interview and observational data used development of thematic codes measuring occupational control. Results: Brothel-based female sex workers in China are a heterogeneous population, displaying considerable variability in the organization of life and work, relationships with managers and clients, ability to negotiate condom use, knowledge of sexually transmitted diseases and HIV, and occupational identity, all of which may result in different risks of acquiring HIV. Conclusion: HIV prevention activities in China must focus on sociocultural aspects of sex work. Such interventions depend on detailed knowledge of its organization. The results of this study demonstrate the importance of prevention activities directed at the brothel managers and clients, as well as the sex workers.

    The paper deals with the comparison between a high-end marker-based acquisition system and a low-cost marker-less methodology for the assessment of the human posture during working tasks. The low-cost methodology is based on the use of a single Microsoft Kinect V1 device. The high-end acquisition system is the BTS SMART that requires the use of reflective markers to be placed on the subject's body. Three practical working activities involving object lifting and displacement have been investigated. The operational risk has been evaluated according to the lifting equation proposed by the American National Institute for Occupational Safety and Health. The results of the study show that the risk multipliers computed from the two acquisition methodologies are very close for all the analysed activities. In agreement to this outcome, the marker-less methodology based on the Microsoft Kinect V1 device seems very promising to promote the dissemination of computer-aided assessment of ergonomics while maintaining good accuracy and affordable costs. PRACTITIONER’S SUMMARY: The study is motivated by the increasing interest for on-site working ergonomics assessment. We compared a low-cost marker-less methodology with a high-end marker-based system. We tested them on three different working tasks, assessing the working risk of lifting loads. The two methodologies showed comparable precision in all the investigations.

  17. Malignant hyperthermia

    Full Text Available Abstract Malignant hyperthermia (MH is a pharmacogenetic disorder of skeletal muscle that presents as a hypermetabolic response to potent volatile anesthetic gases such as halothane, sevoflurane, desflurane and the depolarizing muscle relaxant succinylcholine, and rarely, in humans, to stresses such as vigorous exercise and heat. The incidence of MH reactions ranges from 1:5,000 to 1:50,000–100,000 anesthesias. However, the prevalence of the genetic abnormalities may be as great as one in 3,000 individuals. MH affects humans, certain pig breeds, dogs, horses, and probably other animals. The classic signs of MH include hyperthermia to marked degree, tachycardia, tachypnea, increased carbon dioxide production, increased oxygen consumption, acidosis, muscle rigidity, and rhabdomyolysis, all related to a hypermetabolic response. The syndrome is likely to be fatal if untreated. Early recognition of the signs of MH, specifically elevation of end-expired carbon dioxide, provides the clinical diagnostic clues. In humans the syndrome is inherited in autosomal dominant pattern, while in pigs in autosomal recessive. The pathophysiologic changes of MH are due to uncontrolled rise of myoplasmic calcium, which activates biochemical processes related to muscle activation. Due to ATP depletion, the muscle membrane integrity is compromised leading to hyperkalemia and rhabdomyolysis. In most cases, the syndrome is caused by a defect in the ryanodine receptor. Over 90 mutations have been identified in the RYR-1 gene located on chromosome 19q13.1, and at least 25 are causal for MH. Diagnostic testing relies on assessing the in vitro contracture response of biopsied muscle to halothane, caffeine, and other drugs. Elucidation of the genetic changes has led to the introduction, on a limited basis so far, of genetic testing for susceptibility to MH. As the sensitivity of genetic testing increases, molecular genetics will be used for identifying those at risk with

    2010-06-01

    Full Text Available Abstract Background Volunteer caregivers are a critical source of support for the majority of people living with HIV and AIDS in southern Africa, which has extremely high HIV/AIDS prevalence rates. While studies have shown that volunteer caregiving is associated with negative health and socio-economic outcomes, little is known about the positive experiences of volunteers in the home-based care context in South Africa. The purpose of this study is to explore the perception of rewards among volunteers working in home-based care settings. Methods This study uses a qualitative design. Qualitative interviews were conducted with a purposively selected sample of 55 volunteer caregivers using an interview schedule containing open-ended questions. Results Volunteer caregivers derived intrinsic rewards related to self-growth and personal (emotional and psychological development on the job; they also derived satisfaction from community members taking a liking for them and expressing a need for their services. Volunteers felt gratified by the improvements in their health behaviours, which were a direct consequence of the experiences of caring for terminally ill patients with AIDS. Extrinsic rewards came from appreciation and recognition shown by patients and community members. Extrinsic rewards also accrued to volunteers when the services they rendered made their patients happy. Perhaps the greatest sources of extrinsic rewards are skills and competencies acquired from training and experience while caring for their patients, and volunteers' ability to make a difference in the community. Conclusions Insights into volunteer caregiver rewards provide opportunities for policy makers and programme managers to develop a model of home-based care that facilitates the accrual of rewards to volunteers alongside volunteers' traditional duties of patient care. Programme managers could employ these insights in recruiting and assisting volunteers to identify and reflect

    The AEL (aid effectiveness literature) studies the effect of development aid using econometrics on macro data. It contains about 100 papers of which a third analyzes conditional models where aid effectiveness depends upon z, so that aid only works for a certain range of the variable. The key term...... in this family of AEL models is thus an interaction term of z times aid. The leading candidates for z are a good policy index and aid itself. In this paper, meta-analysis techniques are used (i) to determine whether the AEL has established the said interaction terms, and (ii) to identify some of the determinants...... of the differences in results between studies. Taking all available studies in consideration, we find no support for conditionality with respect to policy, while conditionality regarding aid itself is dubious. However, the results differ depending on the authors’ institutional affiliation....

    Epiluminescence microscopy (ELM) strongly improves the separation of different types of cutaneous pigmented lesions (CPL) and facilitates the early diagnosis of cutaneous melanoma (CM). ELM alone is not 100% accurate in routine diagnosis, and should not be considered the only criterion in the diagnosis of high-risk skin lesions. We have however, demonstrated close agreement between ELM classification criteria and histology in 2,731 cutaneous lesions. In the past five years, our Melanoma Cooperative Group has evaluated 61,000 skin lesions from 30,000 individuals and identified 478 cutaneous melanomas. Most newly diagnosed patients had very early stage melanoma [299 (62%) were Stage I (203 Stage IA and 96 Stage IB), by the American Joint Committee on Cancer (AJCC) criteria]. We have compared data from the patient histories and clinical evaluations with ELM-based morphological patterns to better characterize skin lesions and minimize interpretative problems. From these comparisons, we propose new guidelines for the management of CPL to provide a standard diagnostic and therapeutic approaches and to foster the early identification of lesions at risk for malignant transformation.

    This paper presents the State Department's Interagency Working Group (IWG) model for the spread of HIV. The model is fully operational for Pattern 2 (heterosexual blood transmission) and Pattern 3 (heterosexual, homosexual, and IV drug transmission) countries. This model was developed for various uses, including technical research, policy analysis, and support for decision making. Research uses include studying patterns of HIV spread, assessing the relative effect of different processes on the spread of HIV, examining the demographic impact of HIV infections, and comparing the potential impact of behavioral versus medical intervention strategies. The model will be used in workshops where policy makers and health officials can do hands-on scenario analyses, gain qualitative insights into the possible long-term-epidemiological and demographic impact of HIV, gauge the uncertainties in predictions for the future, and study the impact of HIV, gauge the uncertainties in predictions for the future, and study the impact that intervention strategies are likely to have. The computational model uses a deterministic system of differential equations and runs on a 286- or a 386-based IBM-compatible machine under Microsoft Windows. The program requires an input ASCII (text) file to run; all parameters used by the model are input through this file and, therefore, are user-accessible. The software is user-friendly, mouse-driven, and allows for interactive manipulation of input data and visualization and processing of model outputs. 15 refs., 13 figs., 1 tab.

  4. Developing a communication skills training program for pharmacists working in Southern African HIV/AIDS contexts: some notes on process and challenges.

    Science.gov (United States)

    Watermeyer, Jennifer

    2011-10-01

    In an attempt to understand why patients do not take medications, researchers are increasingly focusing on how communication processes influence adherence behaviors. Pharmacists have an important role to play in this regard. However, existing communication skills training (CST) programs for pharmacists are not necessarily sensitive to the needs of pharmacists working in specific contexts such as Southern Africa. In addition, CST programs are often poorly described in the literature, lack a theoretical background, and focus excessively on evaluation. This article describes the process of developing a CST program for pharmacists working in Southern African HIV/AIDS contexts, focusing on conceptualization and design. Some shortfalls in current approaches to CST are addressed. A number of sources were consulted during the development phase of the project, including interactional and focus group research, previously developed training models, analysis of currently available CST materials for pharmacists, and a literature review. These are discussed and some attention is also given to the challenges of implementing and evaluating the program. The project highlights the importance of providing CST that is disease- and context-specific, grounded in appropriate research and theoretical frameworks, and based on a rigorous process of development.

  5. The cytologic criteria of malignancy.

    Cytology and cell biology are two separate fields that share a focus on cancer. Cancer is still diagnosed based on morphology, and surprisingly little is known about the molecular basis of the defining structural features. Cytology uses the smallest possible biopsy for diagnosis by reducing morphologic "criteria of malignancy" to the smallest scale. To begin to develop common ground, members of the American Society of Cytopathology Cell Biology Liaison Working Group classify some of the "criteria of malignancy" and review their relation to current cell biology concepts. The criteria of malignancy are extremely varied, apparently reflecting many different pathophysiologies in specific microenvironments. Criteria in Group 1 comprise tissue-level alterations that appear to relate to resistance to anoikis, alterations in cell adhesion molecules, and loss of apical-basal polarity. Criteria in Group 2 reflect genetic instability, including chromosomal and possibly epigenetic instability. Criteria in Groups 3 are subcellular structural changes involving cytoplasmic components, nuclear lamina, chromatin and nucleoli that cannot be accounted for by genetic instability. Some distinct criteria in Group 3 are known to be induced by cancer genes, but their precise structural basis remains obscure. The criteria of malignancy are not closely related to the histogenetic classification of cancers, and they appear to provide an alternative, biologically relevant framework for establishing common ground between cytologists and cell biologists. To understand the criteria of malignancy at a molecular level would improve diagnosis, and likely point to novel cell physiologies that are not encompassed by current cell biology concepts.

    Detection of incidental malignant lesions in the breast has a significant clinical impact not only on healthy individuals but also on patients with known malignant disease. This review describes a spectrum of metastatic breast lesions incidentally detected by FDG PET-CT at staging that may be misinterpreted as second primary malignancy. The common non-mammary malignancies that metastasize to the breast include melanoma, hematopoietic malignancies and epithelial cancers. We present the FDG PET-CT features of incidental non-mammary metastases to the breast that may help distinguish primary breast cancer from metastatic disease and aid in the management of patients with a known malignancy.

  13. Catatonic Symptoms Appearing before Autonomic Symptoms Help Distinguish Neuroleptic Malignant Syndrome from Malignant Catatonia.

    Komatsu, Takayuki; Nomura, Tomohisa; Takami, Hiroki; Sakamoto, So; Mizuno, Keiko; Sekii, Hajime; Hatta, Kotaro; Sugita, Manabu

    A 42-year-old Japanese woman with a 10-year history of schizophrenia was admitted due to a disturbance in consciousness that met the diagnostic criteria for both neuroleptic malignant syndrome (NMS) and malignant catatonia. Despite systemic supportive treatments, the catatonic symptoms preceding autonomic symptoms persisted. The symptoms improved after lorazepam administration, leading to a retrospective diagnosis of malignant catatonia. Catatonia is thought to be caused by a dysfunction of ganmma-aminobutyric acid type A receptors in the cortico-cortical networks of the frontal lobes, which causes hypoactivity of the dopaminergic transmission in the subcortical areas. Identifying the catatonic symptoms preceding autonomic symptoms could aid in distinguishing malignant catatonia from NMS.

    2006-07-01

    Full Text Available Abstract Background The World Health Organization's World health report 2006: Working together for health underscores the importance of human resources for health. The shortage of trained health professionals is among the main obstacles to strengthening low-income countries' health systems and to scaling up HIV/AIDS control efforts. Traditional health practitioners are increasingly depicted as key resources to HIV/AIDS prevention and care. An appropriate and effective response to the HIV/AIDS crisis requires reconsideration of the collaboration between traditional and biomedical health providers (THPs and BHPs. The aim of this paper is to explore biomedical and traditional health practitioners' experiences of and attitudes towards collaboration and to identify obstacles and potential opportunities for them to collaborate regarding care for patients with sexually transmitted infections (STIs and HIV/AIDS. Methods We conducted a cross-sectional study in two Zambian urban sites, using structured questionnaires. We interviewed 152 biomedical health practitioners (BHPs and 144 traditional health practitioners (THPs who reported attending to patients with STIs and HIV/AIDS. Results The study showed a very low level of experience of collaboration, predominated by BHPs training THPs (mostly traditional birth attendants on issues of safe delivery. Intersectoral contacts addressing STIs and HIV/AIDS care issues were less common. However, both groups of providers overwhelmingly acknowledged the potential role of THPs in the fight against HIV/AIDS. Obstacles to collaboration were identified at the policy level in terms of legislation and logistics. Lack of trust in THPs by individual BHPs was also found to inhibit collaboration. Nevertheless, as many as 40% of BHPs expressed an interest in working more closely with THPs. Conclusion There is indication that practitioners from both sectors seem willing to strengthen collaboration with each other. However

    1993-01-01

    The National AIDS Convention in South Africa (NACOSA) in October 1992 was the first real attempt to address HIV/AIDS. In Soweto, government, the African National Congress, nongovernmental organizations, and organized industry and labor representatives worked for 2 days to develop a national plan of action, but it did not result in a united effort to fight AIDS. The highest HIV infection rates in South Africa are among the KwaZulu in Natal, yet the Inkatha Freedom Party did not attend NACOSA. This episode exemplifies the key obstacles for South Africa to prevent and control AIDS. Inequality of access to health care may explain why health workers did not diagnose the first AIDS case in blacks until 1985. Migrant labor, Bantu education, and uprooted communities affect the epidemiology of HIV infection. Further, political and social polarization between blacks and whites contributes to a mindset that AIDS is limited to the other race which only diminishes the personal and collective sense of susceptibility and the volition and aptitude to act. The Department of National Health and Population Development's voluntary register of anonymously reported cases of AIDS specifies 1517 cumulative AIDS cases (October 1992), but this number is low. Seroprevalence studies show between 400,000-450,000 HIV positive cases. Public hospitals cannot give AIDS patients AZT and DDI. Few communities provided community-based care. Not all hospitals honor confidentiality and patients' need for autonomy. Even though HIV testing is not mandatory, it is required sometimes, e.g., HIV testing of immigrants. AIDS Training, Information and Counselling Centers are in urban areas, but not in poor areas where the need is most acute. The government just recently developed in AIDS education package for schools, but too many people consider it improper, so it is not being used. The poor quality education provided blacks would make it useless anyhow. Lifting of the academic boycott will allow South African

    Nowadays, the number of cases in which malignant colorectal polyps are removed is increasing due to colorectal cancer screening programmes. Cancerous polyps are classified into non-invasive high grade neoplasia (NHGN), when the cancer has not reached the muscularis mucosa, and malignant polyps, classed as T1, when they have invaded the submucosa. NHGN is considered cured with polypectomy, while the prognosis for malignant polyps depends on various morphological and histological factors. The prognostic facto...

    Characteristics associated with familial compared with nonfamilial malignant melanoma were assessed. These data were obtained from consecutive prospectively completed questionnaires on 1169 cases of cutaneous malignant melanoma. Of these, 69 patients indicated a positive family history for this cancer. Among the various clinical and histological variables compared, those that significantly correlated with the familial occurrence of malignant melanoma include younger age at first diagnosis, smaller diameter of the lesion, lower Clark level, decreased frequency of nonmelanoma skin cancer, and reduced prevalence of noncutaneous cancer. Increased awareness of malignant melanoma among family members could account for some of these observations. Identification of the familial variety of malignant melanoma has practical implications concerning early detection and prompt intervention.

Methods: 79 patients, undergoing CT/MRI for the examination of suspected lesions and whole-body PET/CT before and after therapy, were included in the study during April 2007-January 2013. The relationship between post-treatment evaluations (CT/MRI and PET and PFS during the follow-up period was examined, using Kaplan-Meier survival analysis. The patients were grouped according to the histological type into Hodgkin’s lymphoma (HL, diffuse large B-cell lymphoma (DLBCL, and other histological types. The association between post-treatment evaluations (PET or PET combined with CT/ MRI and PFS was examined separately. Moreover, the relationship between disease recurrence and serum soluble interleukin-2 receptor, lactic dehydrogenase, and C-reactive protein levels was evaluated before and after the treatment. Results: Patients with incomplete remission on both CT/MRI and PET had a significantly shorter PFS, compared to patients with complete remission on both CT/MRI and PET and those exhibiting incomplete remission on CT/MRI and complete remission on PET (P

    The global prevention and treatment of AIDS achieved the remarkable progress, but the spread trend of AIDS epidemic has not been reversed. Health education has become the important measure for prevention of AIDS in every country. A variety of health education models in prevention of AIDS are promoted and used and the special health education activities to the every kind of AIDS high-risk groups have made certain results. At the same time, phenomenon of separation between knowledge and action has appeared in the process of health education and the health education materials can not meet the needs of the target population requirement. Solution of these problems has become the key of prevention and treatment of AIDS for the next step.%  全球艾滋病防治取得了重要的进展,但艾滋病疫情蔓延的趋势并没有得到逆转。健康教育已经成为各个国家预防艾滋病的重要手段,各种健康教育模式在预防艾滋病工作中的推广使用,对各类艾滋病高危人群的针对性健康教育活动均取得了一定成果。与此同时预防艾滋病的健康教育过程出现了“知行分离”现象,健康教育材料无法满足目标人群需求等问题。解决当前预防艾滋病健康教育中的问题,成为下一步艾滋病防治工作的关键。

    2017-01-01

    Malignant glioma is the most common and a highly aggressive cancer in the central nervous system (CNS). Cancer immunotherapy, strategies to boost the bodys anti-cancer immune responses instead of directly targeting tumor cells, recently achieved great success in treating several human solid tumors. Although once considered immune privileged and devoid of normal immunological functions, CNS is now considered a promising target for cancer immunotherapy, featuring the recent progresses in neurobiology and neuroimmunology and a highly immunosuppressive state in malignant glioma. In this review, we focus on immune checkpoint inhibitors, specifically, antagonizing monoclonal antibodies for programmed cell death protein-1 (PD-1), cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4), and indoleamine 2,3-dioxygenase (IDO). We discuss advances in the working mechanisms of these immune checkpoint molecules, their status in malignant glioma, and current preclinical and clinical trials targeting these molecules in malignant glioma.

    Full Text Available Malignancy is the second most common cause of mortality in the reproductive period and it complicates up to one out of every 1000 pregnancies. When cancer is diagnosed during pregnancy, the management approach must take into consideration both the mother and her fetus. Hematologic cancers diagnosed in pregnancy are not common, resulting in paucity of randomized controlled trials. Diagnosis of such malignancies may be missed or delayed, as their symptoms are similar to those encountered during normal pregnancy. Also, many imaging studies may be hazardous during pregnancy. Management of these malignancies during pregnancy induces many treatment-related risks for mother and baby and should consider patient’s preferences for pregnancy continuation. In this article, hematologic malignancies diagnosed in pregnant patients including acute leukemias, chronic myeloid leukemia, lymphomas, multiple myeloma and myeloproliferative neoplasms, will be reviewed, including diagnostic and management strategies and their impact on the pregnant patient and the developing fetus.

    Full Text Available Introduction: HIV-infected patients have a higher risk of developing cancer than the general population. Kaposi's sarcoma (KS, non-Hodgkin's lymphoma (NHL, primary CNS lymphoma (PCL and invasive cervical cancers are considered AIDS-defining. An increased incidence in recent years, however, has been reported also for other malignancies after the introduction of HAART. Methods: We performed a case-control study to characterize all HIV-infected patients with both AIDS and non-AIDS-defining neoplasms observed among all consecutive patients followed at the Infectious Diseases Unit of Pescara General Hospital, since 1991 through 2012. All cases were matched with equinumerous controls without neoplasia homogeneous for age, sex and AIDS diagnosis. Results: Out of 626 patients consecutively assisted since 1991, 57 cases of malignancy (9.1% were observed. Of these, 45 (79.0% occurred in males; mean age was 43.6±9.3 years; 49 (86.0% patients were diagnosed with AIDS. Tumors observed were: NHL, 17 (29.8%; SK, 13 (22.8%; HCC, 5 (8.8%; CPL, 6 (10.5%; Hodgkin's lymphoma, 4 (7.0%; solid tumors, 12 (21.1%, including 1 AIDS-defining tumor (anal cancer. Among these, 37 (66.1% patients died; of them 14 (37.8% had non-AIDS cancers. Cases were well matched with the 55 controls for sex (p=0.9, age (p=0.6 and AIDS diagnosis (p=0.6. In comparison with controls, CD4 nadirs were not different (153±151 in controls vs 136±154 cells/mmc, while CD4 at tumor diagnosis were very different between controls (463±283 cells/mmc and cases (226±209 cells/mmc, p<0.0001.

    Thirty pathological y diagnosed patients with grade III-IV primary or recurrent malignant glioma (tumor diameter 3-7 cm) were randomly divided into two groups. The control group underwent conventional radiotherapy and chemotherapy. In the hyperthermia group, primary cases received hyperthermia treatment, and patients with recurrent tumors were treated with hyperthermia in com-bination with radiotherapy and chemotherapy. Hyperthermia treatment was administered using a 13.56-MHz radio frequency hyperthermia device. Electrodes were inserted into the tumor with the aid of a CT-guided stereotactic apparatus and heat was applied for 1 hour. During 3 months after hyperthermia, patients were evaluated with head CT or MRI every month. Gliomas in the hyper-thermia group exhibited growth retardation or growth termination. Necrosis was evident in 80%of the heated tumor tissue and there was a decrease in tumor diameter. Our findings indicate that ra-dio frequency hyperthermia has a beneficial effect in the treatment of malignant glioma.

    2008-01-01

    Destructive bone lesions occurring in patients who have previously had a malignancy are generally assumed to be a metastasis from that malignancy. We reviewed 60 patients with a previous history of malignancy, who presented with a solitary bone lesion that was subsequently found to be a new and different primary sarcoma of bone. These second malignancies occurred in three distinct groups of patients: (1) patients with original tumours well known to be associated with second malignancies (5%); (2) patients whose second malignancies were likely to be due to the previous treatment of their primary malignancy (40%); (3) patients in whom there was no clearly defined association between malignancies (55%). The purpose of this study is to emphasise the necessity for caution in assuming the diagnosis of a metastasis when a solitary bone lesion is identified following a prior malignancy. Inappropriate biopsy and treatment of primary bone sarcomas compromises limb salvage surgery and can affect patient mortality. PMID:18414590

    1982-08-01

    The most frequent malignant salivary gland tumours are the mucoepidermoid tumour, adenoid cystic carcinoma and adenocarcinoma. The major salivary glands and the minor glands of the mouth and upper respiratory tract may potentially develop any of these malignant lesions. Malignant lesions most frequently present as a palpable mass and tend to enlarge more rapidly than benign neoplasms. Pain, paresthesia, muscle paralysis and fixation to surrounding tissue are all ominous signs and symptoms. The only reliable means of differential diagnosis of these lesions is biopsy and histologic analysis. Therapy involves surgery or a combination of surgery and radiation therapy. The ultimate prognosis is governed by the intrinsic biologic behaviour of the neoplasms, the extent of disease and adequate clinical therapy.

    2006-09-01

    As a subgroup of men who have sex with men (MSM), non-gay-identified (NGI) behaviorally bisexual Latino MSM are associated with heightened probabilities of HIV transmission, yet they have eluded HIV/AIDS interventionists. This exploratory study of Puerto Rican MSM drug users employed multi-session qualitative interviews to examine early life experiences related to gender identity and sexual orientation, and the place of risky drug and sexual behaviors in the process of sexual identity formation. NGI participants experienced sexual debut between ages 13 and 20, and most were recruited to prostitution as young teens by NGI age mates who were also members of drug use networks. Participants emphasized their role as insertive sexual partners and that they maintained relationships with pasivo biological males. It is feasible to recruit NGI MSM through primary male sexual partners and drug use networks. HIV/AIDS prevention based on awareness of developmental histories holds promise for intervening before NGI youth engage in male prostitution or injection drug use.

    2012-01-01

    Gastrointestinal (GI) malignancies are notorious for frequently progressing to advanced stages even in the absence of serious symptoms,thus leading to delayed diagnoses and dismal prognoses.Secondary prevention of GI malignancies through early detection and treatment of cancer-precursor/premalignant lesions,therefore,is recognized as an effective cancer prevention strategy.In order to efficiently detect these lesions,systemic application of screening tests (surveillance) is needed.However,most of the currently used non-invasive screening tests for GI malignancies (for example,serum markers such as alpha-fetoprotein for hepatocellular carcinoma,and fecal occult blood test,for colon cancer) are only modestly effective necessitating the use of highly invasive endoscopy-based procedures,such as esophagogastroduodenoscopy and colonoscopy for screening purposes.Even for hepatocellular carcinoma where non-invasive imaging (ultrasonography) has become a standard screening tool,the need for repeated liver biopsies of suspicious liver nodules for histopathological confirmation can't be avoided.The invasive nature and high-cost associated with these screening tools hinders implementation of GI cancer screening programs.Moreover,only a small fraction of general population is truly predisposed to developing GI malignancies,and indeed needs surveillance.To spare the average-risk individuals from superfluous invasive procedures and achieve an economically viable model of cancer prevention,it's important to identify cohorts in general population that are at substantially high risk of developing GI malignancies (riskstratification),and select suitable screening tests for surveillance in these cohorts.We herein provide a brief overview of such high-risk cohorts for different GI malignancies,and the screening strategies that have commonly been employed for surveillance purpose in them.

    Full Text Available There has been reported increased incidence of ovarian tuberculosis in the tropics since the advent of HIV/AIDS disease. We report a case of bilateral ovarian tuberculosis associated with a single right kidney of uncertain origin in an immunocompetent 15-year-old generally healthy-looking girl. Abdominopelvic scan was equivocal about the diagnosis of the lesion as it failed to differentiate it from malignancy. Tuberculin and histopathology were necessary to confirm the diagnosis of ovarian tuberculosis. Antituberculous medical therapy successfully resolved the disease.

    Full Text Available Most cancer patients are treated with some combination of surgery, radiation, and chemotherapy. Despite recent advances in local therapy with curative intent, chemotherapeutic treatments for metastatic disease often remain unsatisfying due to severe side effects and incomplete long-term remission. Therefore, the evaluation of novel therapeutic options is of great interest. Conventional, along with newer treatment strategies target the immune system that suppresses genitourinary (GU malignancies. Metastatic renal cell carcinoma and non-muscle-invasive bladder caner represent the most immune-responsive types of all human cancer. This review examines the rationale and emerging evidence supporting the anticancer activity of immunotherapy, against GU malignancies.

    2015-01-01

    Full Text Available Malignant gliomas (MG are the most common type of primary malignant brain tumor. Most patients diagnosed with glioblastoma (GBM, the most common and malignant glial tumor, die within 12-15 months. Moreover, conventional treatment, which includes surgery followed by radiation and chemotherapy, can be highly toxic by causing nonspecific damage to healthy brain and other tissues. The shortcomings of standard-of-care have thus created a stimulus for the development of novel therapies that can target central nervous system (CNS-based tumors specifically and efficiently, while minimizing off-target collateral damage to normal brain. Immunotherapy represents an investigational avenue with the promise of meeting this need, already having demonstrated its potential against B-cell malignancy and solid tumors in clinical trials. T-cell engineering with tumor-specific chimeric antigen receptors (CARs is one proven approach that aims to redirect autologous patient T-cells to sites of tumor. This platform has evolved dramatically over the past two decades to include an improved construct design, and these modern CARs have only recently been translated into the clinic for brain tumors. We review here emerging immunotherapeutic platforms for the treatment of MG, focusing on the development and application of a CAR-based strategy against GBM.

    Dickson, Paxton V; Davidoff, Andrew M

    2006-05-01

    Head and neck masses represent a common clinical entity in children. In general, these masses are classified as developmental, inflammatory, or neoplastic. Having a working knowledge of lesions within this region and conducting a thorough history and physical examination generally enables the clinician to facilitate an appropriate workup and establish a diagnosis. The differential diagnosis is broad, and expeditiously distinguishing benign from malignant masses is critical for instituting a timely multidisciplinary approach to the management of malignant lesions. Neoplasms of the head and neck account for approximately 5% of all childhood malignancies. A diagnosis of malignancy may represent a primary tumor or metastatic foci to cervical nodes. In this review, we discuss the general approach to evaluating suspicious masses and adenopathy in the head and neck region and summarize the most common malignant neoplasms of the head and neck with regard to their incidence, clinical presentation, diagnostic evaluation, staging, and management. Thyroid, parathyroid, and salivary gland tumors are discussed elsewhere in this issue of Seminars in Pediatric Surgery.

    Hyaluronan, a major macropolysaccharide in the extracellular matrix of connective tissues, is intimately involved in the biology of cancer. Hyaluronan accumulates into the stroma of various human tumors and modulates intracellular signaling pathways, cell proliferation, motility and invasive properties of malignant cells. Experimental and clinicopathological evidence highlights the importance of hyaluronan in tumor growth and metastasis. A high stromal hyaluronan content is associated with poorly differentiated tumors and aggressive clinical behavior in human adenocarcinomas. Instead, the squamous cell carcinomas and malignant melanomas tend to have a reduced hyaluronan content. In addition to the stroma-cancer cell interaction, hyaluronan can influence stromal cell recruitment, tumor angiogenesis and epithelial-mesenchymal transition. Hyaluronan receptors, hyaluronan synthases and hyaluronan degrading enzymes, hyaluronidases, are involved in the modulation of cancer progression, depending on the tumor type. Furthermore, intracellular signaling and angiogenesis are affected by the degradation products of hyaluronan. Hyaluronan has also therapeutic implications since it is involved in multidrug resistance.

    Full Text Available Malignant catatonia is an unusual and highly fatal neuropsychiatric condition which can present with clinical and biochemical manifestations similar to those of pheochromocytoma. Differentiating between the two diseases is essential as management options greatly diverge. We describe a case of malignant catatonia in a 20-year-old male who presented with concurrent psychotic symptoms and autonomic instability, with markedly increased 24-hour urinary levels of norepinephrine at 1752 nmol/day (normal, 89–470 nmol/day, epinephrine at 1045 nmol/day (normal, <160 nmol/day, and dopamine at 7.9 μmol/day (normal, 0.4–3.3 μmol/day. The patient was treated with multiple sessions of electroconvulsive therapy, which led to complete clinical resolution. Repeat urine collections within weeks of this presenting event revealed normalization or near normalization of his catecholamine and metanephrine levels. Malignant catatonia should be considered in the differential diagnosis of the hypercatecholamine state, particularly in a patient who also exhibits concurrent catatonic features.

    Twenty gastrointestinal lipomata in 18 patients are reviewed: 15 located in the colon, 3 in the distal ileum, one in the duodenum, and one in the stomach. They were found most frequently in European-born, elderly women and presented with variable abdominal symptomatology. Four lipomata were removed during endoscopy, the remainder at laparotomy, partial colectomy being performed in 10 cases. All, except 2 subserosal types, were located in the submucosa, and their average size was 2.7 cm diameter. Microscopically, none showed true encapsulation, and all were composed of mature fat cells without cellular atypia. In spite of nonspecific changes at endoscopy, one-half of the cases showed, on microscopic examination, atrophy of the overlying glands and a prominent eosinophilic and/or lymphoplasmocytic infiltration of the lamina propria. Two large subserosal lipomata were associated with Crohn's disease. In addition, in 39% of cases, malignant tumours, either single or double, were present in the gastrointestinal tract or elsewhere. Gastrointestinal "lipomata" are located in the sites of normal fatty infiltration in the elderly; these growths could be a local aging or reactive process of the intestinal wall rather than true neoplasms without any potential malignancy. However, coexistent malignancies should be carefully searched for in elderly patients with colonic lipoma.

    If employees have to carry out operations with mineral particulate matter or if such blends - due to processes or operations interfere with the breathing air at the work place, power plant operators have to assess and determine the hazards for employees and must introduce corresponding protection measures. Between 2006 and 2008 the Accident Prevention and Insurance Association ''Energy, Textile and Electrics'' has carried out work place measurements in coalfired power plants (lignite and bard coal) in order to provide support when determining and assessing the hazard potential. The measuring results showed that normally the limit values for work places are safely met for A and E fractions. Further dust measurements will be carried out. (orig.)

    Jin-Ha Yoon

    Full Text Available BACKGROUND: Foundry work is associated with serious occupational hazards. Although several studies have investigated the health risks associated with foundry work, the results of these studies have been inconsistent with the exception of an increased lung cancer risk. The current study evaluated the mortality of Korean foundry workers due to malignant and non-malignant diseases. METHODS: This study is part of an ongoing investigation of Korean foundry workers. To date, we have observed more than 150,000 person-years in male foundry production workers. In the current study, we stratified mortality ratios by the following job categories: melting-pouring, molding-coremaking, fettling, and uncategorized production work. We calculated standard mortality ratios (SMR of foundry workers compare to general Korean men and relative risk (RR of mortality of foundry production workers reference to non-production worker, respectively. RESULTS: Korean foundry production workers had a significantly higher risk of mortality due to malignant disease, including stomach (RR: 3.96; 95% CI: 1.41-11.06 and lung cancer (RR: 2.08; 95% CI: 1.01-4.30, compared with non-production workers. High mortality ratios were also observed for non-malignant diseases, including diseases of the circulatory (RR: 1.92; 95% CI: 1.18-3.14, respiratory (RR: 1.71; 95% CI: 1.52-21.42 for uncategorized production worker, and digestive (RR: 2.27; 95% CI: 1.22-4.24 systems, as well as for injuries (RR: 2.36; 95% CI: 1.52-3.66 including suicide (RR: 3.64; 95% CI: 1.32-10.01. CONCLUSION: This study suggests that foundry production work significantly increases the risk of mortality due to some kinds of malignant and non-malignant diseases compared with non-production work.

    Short, R V

    1989-06-01

    This article reviews a peer group Acquired Immunodeficiency Syndrome (AIDS) educational program at a university in Australia. Studies in the US have shown that most adolescents, although sexually active, do not believe they are likely to become infected with the Human Immunodeficiency Virus, and therefore do not attempt to modify their sexual behavior. A 1st step in educating students is to introduce them to condoms and impress upon them the fact that condoms should be used at the beginning of all sexual relationships, whether homosexual or heterosexual. In this program 3rd year medical students were targeted, as they are effective communicators and disseminators of information to the rest of the student body. After class members blow up condoms, giving them a chance to handle various brands and observe the varying degrees of strength, statistical evidence about the contraceptive failure rate of condoms (0.6-14.7 per 100 women-years) is discussed. Spermicides, such as nonoxynol-9 used in conjunction with condoms, are also discussed, as are condoms for women, packaging and marketing of condoms, including those made from latex and from the caecum of sheep, the latter condoms being of questionable effectiveness in preventing transmission of the virus. The care of terminal AIDS cases and current global and national statistics on AIDS are presented. The program also includes cash prizes for the best student essays on condom use, the distribution of condoms, condom key rings and T-shirts, and a student-run safe sex stand during orientation week. All of these activities are intended to involve students and attract the interest of the undergraduate community. Questionnaires administered to students at the end of the course revealed that the lectures were received favorably. Questionnaires administered to new medical and English students attending orientation week revealed that 72% of students thought the stand was a good idea and 81% and 83%, respectively found it

  5. Educating Brazilian workers about AIDS.

    Science.gov (United States)

    1991-12-01

    This article contains a the script for a slide-tape presentation entitled Working Against AIDS, a presentation developed by the Brazil Family Planning Association (BEMFAM) which is designed to debunk common misconceptions about the disease. This audio-visual, which targets Brazilian workers, can be used during talks, seminars, and meetings. A discussion of the issues involved usually follows the presentation of Working Against AIDS. The presentation contains 30 illustrated slides (these are included in the article). The presentation begins by explaining that much of the information concerning AIDS is prejudicial and misleading. The next few slides point out some of the common misconceptions about AIDS, such as claims denying the existence of the disease, or suggestions that only homosexuals and prostitutes are at risk. The presentation then goes on to explain the ways in which the virus can and cannot be transmitted. Then it discusses how the virus destroys the body's natural defenses and explains the ensuing symptoms. Slides 14 and 15 point out that no cure yet exists for AIDS, making prevention essential. Slides 16-23 explain what actions are considered to be high risk and which ones do not entail risk. Noting that AIDS can be prevented, slide 24 says that the disease should not present an obstacle to spontaneous manifestations of human relations. The next slide explains that condoms should always be used when having sex with someone who could be infected with AIDS. Finally slides 26-30 demonstrate the proper way to use and dispose of a condom.

  6. Aid Efficacy: An Institutional Approach

    José Antonio Alonso Rodríguez

    2006-01-01

    Full Text Available This work aims to explore some of the weaknesses that the international aid system presents for efficaciously operating in promoting development. For this, it adopts an institutionalapproach, attempting to investigate the problems of asymmetry in information that occur both in relationships between donor and receiver and within aid organisations. The analysis of these aspects leads the author to underscore the importance that learning processes have in enriching interventions in development; he also underscores the importance of the attitudes and aptitudes of the agents in fostering these processes of improvement in aid quality.

  7. Cell Cycle Regulates Nuclear Stability of AID and Determines the Cellular Response to AID.

    2015-09-01

    Full Text Available AID (Activation Induced Deaminase deaminates cytosines in DNA to initiate immunoglobulin gene diversification and to reprogram CpG methylation in early development. AID is potentially highly mutagenic, and it causes genomic instability evident as translocations in B cell malignancies. Here we show that AID is cell cycle regulated. By high content screening microscopy, we demonstrate that AID undergoes nuclear degradation more slowly in G1 phase than in S or G2-M phase, and that mutations that affect regulatory phosphorylation or catalytic activity can alter AID stability and abundance. We directly test the role of cell cycle regulation by fusing AID to tags that destabilize nuclear protein outside of G1 or S-G2/M phases. We show that enforced nuclear localization of AID in G1 phase accelerates somatic hypermutation and class switch recombination, and is well-tolerated; while nuclear AID compromises viability in S-G2/M phase cells. We identify AID derivatives that accelerate somatic hypermutation with minimal impact on viability, which will be useful tools for engineering genes and proteins by iterative mutagenesis and selection. Our results further suggest that use of cell cycle tags to regulate nuclear stability may be generally applicable to studying DNA repair and to engineering the genome.

    Full Text Available Gregor DresemannCenter for Neurooncology at Aerztehaus Velen, Velen, GermanyAbstract: Glioblastoma multiforme WHO grade IV (GBM is the most aggressive ­malignant glioma and the most frequent primary tumor of the central nervous system. The median ­survival of newly diagnosed GBM patients was between 9 to 12 months prior to treatment with ­temozolomide being introduced. Primary resection that is as complete as possible is recommended for malignant glioma. Conventional fractionated irradiation 55 to 60 gy with concomitant temozolomide followed by standard temozolomide 6 cycles (5/28 (EORTC/NCIC-regime published by R Stupp in 2005 is the standard of care for newly diagnosed GBM after surgery, independent of the methylation status of the MGM-T gene promoter. Age is no ­contraindication for treatment with temozolomide, although comorbidity and performance status have to be ­considered. For temozolomide naive GBM and astrocytoma grade III patients with disease progression, temozolomide is still the treatment of choice outside of clinical studies. A ­general consensus regarding the schedule of choice has not yet been achieved; so far the 5 out of 28 days regimen (5/28 is the standard of care in most countries. Patients with disease progression after standard temozolomide (5/28 are candidates for clinical studies. Outside of clinical ­studies, dose-dense (7/7, prolonged (21/28, or metronomic (28/28 temozolomide, or alternatively a nitrosourea-based regimen can be an option. The excellent toxicity profile of ­temozolomide allows for various combinations with antitumor agents. None of these ­combinations, however, have been demonstrated to be statistically significantly superior compared to temozolomide alone. The role of lower dosed, dose-dense, or continuous regimen with or without drug combination and the role of temozolomide for newly diagnosed astrocytoma grade III and low grade glioma still has to be determined.Keywords: glioblastoma

There is no optimal and effective treating consensus so far. We report three patients of MPM treated at Mackay Memorial Hospital in recent 3 years. They were two men and one woman without asbestos exposure related to their occupations. Due to failure in early diagnosis of MPM, none of them survived for more than 5 months. We make a brief review from the previous literature. These three cases were compared with the reviewing data in many aspects including the risk factor, clinical presentation, diagnostic options, and management. Besides, some latest clinical trials are introduced in this report.

The objective of this study was to investigate the profile of cases of NMS and to compare our findings with those published in similar settings. A series of 18 consecutive patients with an established diagnosis of NMS was analyzed, gathering data on demography, symptoms and signs. Two thirds of all cases involved woman with a past medical history of psychiatric disorder receiving relatively high doses of AP. The signs and symptoms of NMS episodes were similar to those reported in other series and only one case had a fatal outcome, the remaining presenting complete recovery. As expected, more than two thirds of our cases were using classic AP (68%, however the clinical profile of these in comparison with those taking newer agent was similar. Newer AP also carry the potential for NMS.

    Full Text Available Background. In 1999, An Oral Health Survey of American Indian and Alaska Native (AI/AN Dental Patients found that 79% of 2- to 5-year-olds had a history of tooth decay. The Alaska Native Tribal Health Consortium in collaboration with Alaska’s Tribal Health Organizations (THO developed a new and diverse dental workforce model to address AI/AN oral health disparities. Objectives. This paper describes the workforce model and some experience to date of the Dental Health Aide (DHA Initiative that was introduced under the federally sanctioned Community Health Aide Program in Alaska. These new dental team members work with THO dentists and hygienists to provide education, prevention and basic restorative services in a culturally appropriate manner. Results. The DHA Initiative introduced 4 new dental provider types to Alaska: the Primary Dental Health Aide, the Expanded Function Dental Health Aide, the Dental Health Aide Hygienist and the Dental Health Aide Therapist. The scope of practice between the 4 different DHA providers varies vastly along with the required training and education requirements. DHAs are certified, not licensed, providers. Recertification occurs every 2 years and requires the completion of 24 hours of continuing education and continual competency evaluation. Conclusions. Dental Health Aides provide evidence-based prevention programs and dental care that improve access to oral health care and help address well-documented oral health disparities.

    CONCLUSION: To our knowledge this is the eighth adult case of primary intrahepatic malignant mesothelioma reported in the literature. These tumors are rarely diagnosed preoperatively. Absence of previous asbestos exposure does not exclude malignant mesothelioma from the differential diagnosis. Proper surgical treatment may offer prolonged survival to the patient, without adjuvant therapy.

  4. Crawling Aid

    Science.gov (United States)

    1982-01-01

    The Institute for the Achievement of Human Potential developed a device known as the Vehicle for Initial Crawling (VIC); the acronym is a tribute to the crawler's inventor, Hubert "Vic" Vykukal; is an effective crawling aid. The VIC is used by brain injured children who are unable to crawl due to the problems of weight-bearing and friction, caused by gravity. It is a rounded plywood frame large enough to support the child's torso, leaving arms and legs free to move. On its underside are three aluminum discs through which air is pumped to create an air-bearing surface that has less friction than a film of oil. Upper side contains the connection to the air supply and a pair of straps which restrain the child and cause the device to move with him. VIC is used with the intent to recreate the normal neurological connection between brain and muscles. Over repetitive use of the device the child develops his arm and leg muscles as well as coordination. Children are given alternating therapy, with and without the VIC until eventually the device is no longer needed.

    Full Text Available Abstract The AIDS Cancer and Specimen Resource (ACSR supports scientific discovery in the area of HIV/AIDS-associated malignancies. The ACSR was established as a cooperative agreement between the NCI (Office of the Director, Division of Cancer Treatment and Diagnosis and regional consortia, University of California, San Francisco (West Coast, George Washington University (East Coast and Ohio State University (Mid-Region to collect, preserve and disperse HIV-related tissues and biologic fluids and controls along with clinical data to qualified investigators. The available biological samples with clinical data and the application process are described on the ACSR web site. The ACSR tissue bank has more than 100,000 human HIV positive specimens that represent different processing (43, specimen (15, and anatomical site (50 types. The ACSR provides special biospecimen collections and prepares speciality items, e.g., tissue microarrays (TMA, DNA libraries. Requests have been greatest for Kaposi's sarcoma (32% and non-Hodgkin's lymphoma (26%. Dispersed requests include 83% tissue (frozen and paraffin embedded, 18% plasma/serum and 9% other. ACSR also provides tissue microarrays of, e.g., Kaposi's sarcoma and non-Hodgkin's lymphoma, for biomarker assays and has developed collaborations with other groups that provide access to additional AIDS-related malignancy specimens. ACSR members and associates have completed 63 podium and poster presentations. Investigators have submitted 125 letters of intent requests. Discoveries using ACSR have been reported in 61 scientific publications in notable journals with an average impact factor of 7. The ACSR promotes the scientific exploration of the relationship between HIV/AIDS and malignancy by participation at national and international scientific meetings, contact with investigators who have productive research in this area and identifying, collecting, preserving, enhancing, and dispersing HIV/AIDS

  10. A Computer-Aided Diagnosis for Evaluating Lung Nodules on Chest CT: the Current Status and Perspective

    Energy Technology Data Exchange (ETDEWEB)

    Goo, Jin Mo [Seoul National University Medical Research Center, Seoul (Korea, Republic of)

    2011-04-15

    As the detection and characterization of lung nodules are of paramount importance in thoracic radiology, various tools for making a computer-aided diagnosis (CAD) have been developed to improve the diagnostic performance of radiologists in clinical practice. Numerous studies over the years have shown that the CAD system can effectively help readers identify more nodules. Moreover, nodule malignancy and the response of malignant lung tumors to treatment can also be assessed using nodule volumetry. CAD also has the potential to objectively analyze the morphology of nodules and enhance the work flow during the assessment of follow-up studies. Therefore, understanding the current status and limitations of CAD for evaluating lung nodules is essential to effectively apply CAD in clinical practice

    From October 1986 to June 1989, 79 patients with malignant tumors were treated by radiation therapy combined with hyperthermia at National Medical Center Hospital. Seventy two patients (male: 48, female: 23) were evaluable. Average age was 62.4 years old (ranged 20-81 years old). Irradiation was delivered twice to fifth weekly in tumor doses of 50 to 60 Gy (TDF 82-122). We used 3 types of hyperthermic equipment, Thermotron RF8, BSD 1000 System and Endoradiotherm 100A. Hyperthermia was initiated within 30 minutes following irradiation, most of the patients being treated with adequate equipment, 41-44degC, for 60-70 minutes every 72 hours. Fifteen of 71 patients (20.8%) showed a complete response and 36 patients (50%) showed a partial response, so effective rate was 70.8% of all. In superficial tumors, 4 of 21 patients (21.5%) showed a complete response and 8 of 21 patients showed a partial response, effective rate was 63.2% of all. In deep seated tumor, 10 of 46 patients (21.7%) showed a complete response and 25 of all patients showed a partial response, so effective rate was 76.1% of all. Five patients were heated following only intra-tumor injection of OK-432 and its effective rate was 75%. We think that this modality of therapy will be effective in cases which heating area had been irradiated over tolerable doses. CR rate of superficial tumors according to intra-tumor center temperature tends to higher in the cases of higher tumor temperature. In deep seated tumor, 11 patients (23.9%) had reached over 43degC, 29 patients (63.0%) heated 41-43degC, 6 patients (13.0%) heated under 41degC and CR rate of each group were 36.4%, 17.2%, 16.7%, respectively. We think that thermotherapy with irradiation is an effective therapy in the treatment of malignancies but the improvement of heating equipment will be expected. (author).

  12. Increasing Deaths Due to Malignancy in HIV+ Patients is Associated with Integrase Inhibitor Therapy

    Despite reductions in AIDS-related deaths, registries show HIV+ patients are still dying at a younger age than HIV-peers. Although overall mortality has declined in this population, a growing percent of deaths are due to malignancy. Since the data demonstrating the growing percentage of deaths due to malignancy in the HIV+ population is derived from registries, the study explores whether the subset dying from malignancy has particular characteristics that can be seen in a well-characterized cohort. In the well-characterized HIV+ cohort, the percentage of deaths due to cancer was seen to increase over four years (2010-2013) from 21% to 24% to 38% to 40%. The mean CD4-count of those who died from malignancy was 252+/-42 and 333+/-36 in patients with death from other causes. The viral load was not suppressed in 26% of patients dying from malignancy. Of patients on integrase inhibitor therapy, 48% of deaths were due to malignancy while in patients not on this therapy, 10% of deaths were due to malignancy (relative risk = 4.8). In HIV+ patients, a low CD4-count, failure to achieve viral suppression, and use of integrase inhibitors were associated with malignancy as the cause of death. The association of a specific therapy, integrase inhibition, with malignancy is seen in the study.

    Liedlgruber, Michael; Uhl, Andreas

    2011-01-01

    Today, medical endoscopy is a widely used procedure to inspect the inner cavities of the human body. The advent of endoscopic imaging techniques-allowing the acquisition of images or videos-created the possibility for the development of the whole new branch of computer-aided decision support systems. Such systems aim at helping physicians to identify possibly malignant abnormalities more accurately. At the beginning of this paper, we give a brief introduction to the history of endoscopy, followed by introducing the main types of endoscopes which emerged so far (flexible endoscope, wireless capsule endoscope, and confocal laser endomicroscope). We then give a brief introduction to computer-aided decision support systems specifically targeted at endoscopy in the gastrointestinal tract. Then we present general facts and figures concerning computer-aided decision support systems and summarize work specifically targeted at computer-aided decision support in the gastrointestinal tract. This summary is followed by a discussion of some common issues concerning the approaches reviewed and suggestions of possible ways to resolve them.

  14. Plexiform Neurofibroma of the Wrist: Imaging Features and When to Suspect Malignancy

    Directory of Open Access Journals (Sweden)

    Maria Gosein

    2013-01-01

    Full Text Available Plexiform neurofibromas are essentially pathognomonic for neurofibromatosis type 1 (NF1, occurring when there is diffuse involvement along a nerve segment and its branches. Transformation into a malignant peripheral nerve sheath tumour (MPNST is a major cause of mortality in NF1 patients. These tumours are highly aggressive and particularly difficult to diagnose in NF1 patients due to the clinical overlap between benign and malignant lesions. We present a case of a plexiform neurofibroma and discuss the typical imaging characteristics on ultrasound, CT, and MRI, including the target sign and continuity with the parent nerve. Certain imaging features should raise suspicion for malignancy however, these modalities may not always reliably differentiate between benign and malignant lesions. Recent studies show a very high negative predictive value for FDG-PET making it quite useful in excluding malignancy. In positive scans, PET/CT aids in guiding biopsy to the most metabolically active area of the tumour.

  17. Malignancy and chronic renal failure.

    Science.gov (United States)

    Peces, Ramon

    2003-01-01

    Increased incidence of cancer at various sites is observed in patients with end-stage renal disease (ESRD). Certain malignant diseases, such as lymphomas and carcinomas of the kidney, prostate, liver and uterus, show an enhanced prevalence compared with the general population. In particular, renal cell carcinoma (RCC) shows an excess incidence in ESRD patients. A multitude of factors, directly or indirectly associated with the renal disease and the treatment regimens, may contribute to the increased tumor formation in these patients. Patients undergoing renal replacement therapy (RRT) are prone to develop acquired cystic kidney disease (ACKD), which may subsequently lead to the development of RCC. In pre-dialysis patients with coexistent renal disease, as in dialysis and transplant patients, the presence of ACKD may predispose to RCC. Previous use of cytotoxic drugs (eg, cyclophosphamide) or a history of analgesic abuse, are additional risk factors for malignancy. Malignancy following renal transplantation is an important medical problem during the follow-up. The most common malignancies are lymphoproliferative disorders (early after transplantation) and skin carcinomas (late after transplantation). Another important confounder for risk of malignancy after renal transplantation is the type of immunosuppression. The type of malignancy is different in various countries and dependent on genetic and environmental factors. Finally, previous cancer treatment in a uremic patient on the transplant waiting list is of great importance in relation to waiting time and post-malignancy screening.

    Full Text Available Ewing's sarcoma (ES is a rare tumor that is most common in children and young adults. Late effects of ES therapy include second cancers, a tragic outcome for survivors of such a young age. This paper will explore the frequencies and types of malignancies that occur after ES. Additionally, it will review how second malignancies have changed with the shift in treatment from high-dose radiation to chemotherapy regimens including alkylators and epipodophyllotoxins. The risk of additional cancers in ES survivors will also be compared to survivors of other childhood cancers. Finally, the possible genetic contribution to ES and second malignancies will be discussed.

    Full Text Available Renal malignancies are common in children. While the majority of malignant renal masses are secondary to Wilms tumor, it can be challenging to distinguish from more aggressive renal masses. For suspicious renal lesions, it is crucial to ensure prompt diagnosis in order to select the appropriate surgical procedure and treatment. This review article will discuss the common differential diagnosis that can be encountered when evaluating a suspicious renal mass in the pediatric population. This includes clear cell sarcoma of the kidney, malignant rhabdoid tumor, renal medullary carcinoma and lymphoma.

    This study reviews a series of 811 malignant pleural mesothelioma cases, diagnosed at hospitals in Trieste and Monfalcone districts of north eastern Italy, a narrow coastal strip with a population of about three lakh, in the period 1968-2008. The diagnosis was based on histological examination in 801 cases, and cytological findings in 10. Necropsy was performed in 610 cases. Occupational histories were obtained directly from the patients or their relatives through personal or telephone interviews. Routine lung sections were examined for asbestos bodies in 500 cases. In 143 cases asbestos bodies were isolated and counted by chemical digestion of the lung tissue using the Smith-Naylor method. The series included 717 men and 94 women aged between 32 and 93 years (mean 69.2 years). Detailed occupational data was obtained for 732 cases.The majority of patients had marine jobs - shipbuilding (449 cases), maritime trades (56 cases), and port activities (39 cases). The nature of work of other patients included a variety of occupations, with non-shipbuilding industries being the most common. Thirty-four women cleaned the work clothes of family members occupationally exposed and hence had a history of asbestos exposure at home. Most of the patients had their first exposure to asbestos before 1960. The latency period ranged between 13 and 73 years (mean 48.2). Latency period among insulators and dock workers were shorter than other categories. Asbestos bodies were detected on routine lung sections in 343 cases (68.6%). Lung asbestos body burdens after isolation ranged between two to 10 millions bodies per gram of dried tissue. Despite some limitations in the use of asbestos in this area since the 1970s, the incidence of tumor remained high during the last years.

    Primary fallopian tube carcinoma (PFTC) is a rare malignant carcinoma among all genital tract malignancies. It occurs most commonly in postmenopausal women and is similar to ovarian malignancy historically and clinically. Because of its insidious onset and silent course, the diagnosis is made usually postoperatively. Liquid-based cytology (LBC) is a type of method for cervical cancer screening, but sometimes it may aid in making PFTC diagnosis. We report a 47-year-old woman with PFTC, whose diagnosis was made with the aid of LBC.

    Rapid regression of all symptoms was obtained after moderate chemotherapy in two women aged 69 and 77 years respectively with malignant non-Hodgkin's lymphomas. Cervico-facial locations of these tumors are discussed in relation to definition, etiology, geographic factors, genetic markers, and associated immunologic disorders. Diagnosis requires a series of explorations including, obviously as a last resort, exploratory cervicotomy. Other regions may be involved and must be investigated, but lesions not affecting lymph nodes occur in only approximately 2 p. cent of patients with cervico-facial malignant non-Hodgkin's lymphoma (approximately 10 p. cent of all malignant non-Hodgkin's lymphomas). Other localizations include the hard palate, gums, sinuses, and salivary glands. Burkitt's lymphoma represents, on the contrary, 30 p. cent of malignant non-Hodgkin's lymphoma seen in European children. The different therapeutic modalities available are discussed.

    Full Text Available Telomerase expression and telomere maintenance are critical for cell proliferation and survival, and they play important roles in development and cancer, including hematological malignancies. Transcriptional regulation of the rate-limiting subunit of human telomerase reverse transcriptase gen (hTERT is a complex process, and unveiling the mechanisms behind its reactivation is an important step for the development of diagnostic and therapeutic applications. Here, we review the main mechanisms of telomerase activation and the associated hematologic malignancies.

    Full Text Available The breast cancer detection and diagnosis is a critical and complex procedure that demands high degree of accuracy. In computer aided diagnostic systems, the breast cancer detection is a two stage procedure. First, to classify the malignant and benign mammograms, while in second stage, the type of abnormality is detected. In this paper, we have developed a novel architecture to enhance the classification of malignant and benign mammograms using multi-classification of malignant mammograms into six abnormality classes. DWT (Discrete Wavelet Transformation features are extracted from preprocessed images and passed through different classifiers. To improve accuracy, results generated by various classifiers are ensembled. The genetic algorithm is used to find optimal weights rather than assigning weights to the results of classifiers on the basis of heuristics. The mammograms declared as malignant by ensemble classifiers are divided into six classes. The ensemble classifiers are further used for multiclassification using one-against-all technique for classification. The output of all ensemble classifiers is combined by product, median and mean rule. It has been observed that the accuracy of classification of abnormalities is more than 97% in case of mean rule. The Mammographic Image Analysis Society dataset is used for experimentation.

    实践体验对于工商类本科教学至关重要。当前“90后”大学生接受的信息量大、思维快、讲求实际。针对学生的以上特点,除了选用教材案例作为间接素材运用于教学,也通过实践后提出,在一定的控制条件下,可以尝试让本科生参与部分科研辅助性工作,作为教学的实践案例,以提高整体教学效果,实现二类本科学校培养“有特色、应用型创新人才“的目标。相应地,教学环节和教师在教学中的作用也需要进行一系列的变革。%Practical experience is essential for the business undergraduate teaching. At present, college students borned in the 1990s receive a large amount of information, have fast thinking patterns, and have a practical attitude. For the above characteristics of the students, in addition to the selection of textbook cases as indirect materials used in teaching, researchers propose, through the practice of teaching reform, that teachers can try to let students participate in a part of aided work of science and research under certain controlled conditions which can be taken as the direct cases of teaching to improve the overall teaching effect. This can help realize the aim of type-two universities: cultivating characteristic innovative talents in application. Correspondingly, the procedures and the roles of teachers in the teaching need a series of reforms.

    Bone marrow oedema is associated with a wide variety of pathological processes including both benign and malignant bone tumours. This imaging finding in relation to intraosseous tumours can aid in providing a more focused differential diagnosis. In this review, we will discuss the MR imaging of bone marrow oedema surrounding intraosseous neoplasms. The different pulse sequences used in differentiating underlying tumour from surrounding oedema are discussed along with the role of dynamic contrast enhanced MRI. Benign lesions commonly associated with bone marrow oedema include osteoid osteoma, osteoblastoma, chondroblastoma and Langerhan's cell histiocytosis. Metastases and malignant primary bone tumours such as osteosarcoma, Ewing's sarcoma and chondrosarcoma may also be surrounded by bone marrow oedema. The imaging findings of these conditions are reviewed and illustrated. Finally, the importance of bone marrow oedema in assessment of post chemotherapeutic response is addressed.

    Surgery is the only potentially effective treatment of the non-small-cell lung neoplasm. Patient selection for surgery requires a rigorous protocol. In order to optimize the therapeutic strategy, the extension work-up must be designed to identify correctly locoregional spread and any contraindications as well as metastasis with assessment of mediastino-pulmonary lymph nodes. Radiology, particularly computed tomography, is highly contributive. Plain chest X-ray, ultrasound, magnetic resonance imaging (MRI) and possibly positron omission tomography (PET) may also be required. (authors)

  5. Clinical Criteria for Physician Aid in Dying.

    Science.gov (United States)

    Orentlicher, David; Pope, Thaddeus Mason; Rich, Ben A

    2016-03-01

    More than 20 years ago, even before voters in Oregon had enacted the first aid in dying (AID) statute in the United States, Timothy Quill and colleagues proposed clinical criteria AID. Their proposal was carefully considered and temperate, but there were little data on the practice of AID at the time. (With AID, a physician writes a prescription for life-ending medication for a terminally ill, mentally capacitated adult.) With the passage of time, a substantial body of data on AID has developed from the states of Oregon and Washington. For more than 17 years, physicians in Oregon have been authorized to provide a prescription for AID. Accordingly, we have updated the clinical criteria of Quill, et al., based on the many years of experience with AID. With more jurisdictions authorizing AID, it is critical that physicians can turn to reliable clinical criteria. As with any medical practice, AID must be provided in a safe and effective manner. Physicians need to know (1) how to respond to a patient's inquiry about AID, (2) how to assess patient decision making capacity, and (3) how to address a range of other issues that may arise. To ensure that physicians have the guidance they need, Compassion & Choices convened the Physician Aid-in-Dying Clinical Criteria Committee, in July 2012, to create clinical criteria for physicians who are willing to provide AID to patients who request it. The committee includes experts in medicine, law, bioethics, hospice, nursing, social work, and pharmacy. Using an iterative consensus process, the Committee drafted the criteria over a one-year period.

  6. How to perform first aid.

    Gloster, Annabella Satu; Johnson, Phillip John

    2016-01-13

    RATIONALE AND KEY POINTS: This article aims to help nurses to perform first aid in a safe, effective and patient-centred manner. First aid comprises a series of simple, potentially life-saving steps that an individual can perform with minimal equipment. Although it is not a legal requirement to respond to an emergency situation outside of work, nurses have a professional duty to respond and provide care within the limits of their competency. First aid is the provision of immediate medical assistance to an ill or injured person until definitive medical treatment can be accessed. First aid can save lives and it is essential that nurses understand the basic principles. REFLECTIVE ACTIVITY: Clinical skills articles can help update your practice and ensure it remains evidence based. Apply this article to your practice. Reflect on and write a short account of: 1. Your skill in performing first aid and any areas where you may need to extend your knowledge. 2. How reading this article will change your practice.

    1996-09-01

    Two cases of XYY male with refractory anemia with excess of blasts are reported, and previous reported XYY males with hematologic malignancy are reviewed. Altogether 26 cases were collected for analysis: acute myeloid leukemia (10), acute lymphocytic leukemia (seven), acute leukemia (two), chronic myelocytic leukemia (three), myelodysplastic syndrome (three), and essential thrombocythemia (one). The age at the time of diagnosis ranged in age from 7.5 to 81 years. In three of six XYY/XY mosaicism cases, XYY clone was associated with malignancy. However, in two cases XYY clone was not involved. The evidence presented here suggests that the event of an XYY male with hematologic malignancy is incidental rather than a genetic etiology.

    Full Text Available Deciduosis classically occurs in the context of known endometriosis in the pelvis, most commonly in the ovaries, but also in the peritoneum. However, ovarian deciduosis outside the context of endometriosis is rare and makes diagnosis difficult, especially as the sonographic appearance suggests a malignant process. We report a case of decidualized ovarian mass in a patient without prior history of endometriosis that mimicked an ovarian malignancy. MRI may be a useful imaging modality to monitor these lesions and guide management. Consultation with a multidisciplinary team accustomed to such conditions will help to tailor the management to each individual.

    2016-04-01

    With surgery for hepatic malignancy, there are poor options for chemotherapy; many patients are deemed unresectable because of vascular involvement or location of tumors. Over the past few decades, advances in surgical technique have allowed resection of these tumors with vascular reconstruction to achieve negative margins and improve chances for survival. This article reviews those reconstruction techniques and outcomes in detail, including in situ perfusion and ex vivo liver surgery, and provides a discussion of implications and operative planning for patients with hepatic malignancy in order to provide surgeons with better understanding of these complicated operations.

    Full Text Available Introduction Suicide is a conscious and intentional destruction of one’s own life, which occurs as a result of mutual influence of a person’s disposition and motives (facts inspiring the commitment of suicide. It is well known that various diseases, including malignancies, could be important and in some cases the only motive for committing suicide. Objective The purpose of the study was to analyze in detail suicides of persons whose only motive was an established malignant disease. Method The analysis was performed using the autopsy material of the Institute of Forensic Medicine, School of Medicine, University of Belgrade, during the period from 1990 to 2004. The reports on performed medico-legal autopsies were used, as well as history data obtained from the family members of suicidal persons, investigation reports and the available medical documents. Results In 1931 cases there was established suicidal nature of a violent death. Neoplasms were the suicidal motive in 37 persons (1.9%. The basic characteristics of the analyzed sample were predominance of males (26:11, ratio 2.4:1, the age of over 70 years and the highest incidence of malignant lung and breast tumors. Almost all cases were the persons who underwent treatment for malignant neoplasms over a longer period of time. During 19 autopsies (51.3% out of 37, a progressive phase of malignancy was established, i.e. metastases. The data on prior oral announcement of suicide intention were obtained for 70.3% (26 cases, and on previous suicidal attempts only for 13.5% (5 cases. In the majority of cases (78.4% the place of committed suicide was the person’s home. In 16 cases (43.2% the suicide was committed with a firearm. Hanging as a manner of destroying one’s own life was chosen by 12 persons (32.4%, while other ways were less frequently used. Conclusion Although malignancies were not present with high incidence as a suicidal motive in our analyzed sample, such cases require particular

    1991-01-01

    This article considers the epidemic proportion of AIDS in developing countries, and discusses the U.S. Agency for International Development's (USAID) reworked and intensified strategy for HIV infection and AIDS prevention and control over the next 5 years. Developing and launching over 650 HIV and AIDS activities in 74 developing countries since 1986, USAID is the world's largest supporter of anti-AIDS programs. Over $91 million in bilateral assistance for HIV and AIDS prevention and control have been committed. USAID has also been the largest supporter of the World Health Organization's Global Program on AIDS since 1986. Interventions have included training peer educators, working to change the norms of sex behavior, and condom promotion. Recognizing that the developing world will increasingly account for an ever larger share of the world's HIV-infected population, USAID announced an intensified program of estimated investment increasing to approximately $400 million over a 5-year period. Strategy include funding for long-term, intensive interventions in 10-15 priority countries, emphasizing the treatment of other sexually transmitted diseases which facilitate the spread of HIV, making AIDS-related policy dialogue an explicit component of the Agency's AIDS program, and augmenting funding to community-based programs aimed at reducing high-risk sexual behaviors. The effect of AIDS upon child survival, adult mortality, urban populations, and socioeconomic development in developing countries is discussed. Program examples are also presented.

Methods Between 2007 and 2011, 76 neoplasms ≥20 mm in 70 patients were analyzed Results The mean age of the patients was 67.4 years, and 41 were women. Mean lesion size was 24.7 mm ± 6.2 mm (range: 20 to 50 mm. Half of the neoplasms were polypoid and the other half were non-polypoid. Forty-two (55.3% lesions were located in the left colon, and 34 in the right colon. There was a high prevalence of III L (39.5% and IV (53.9% pit patterns. There were 72 adenomas and 4 adenocarcinomas. Malignancy was observed in 5.3% of the lesions. Thirty-three lesions presented advanced histology (adenomas with high-grade dysplasia or early adenocarcinoma, with no difference in morphology and site. Only one lesion (1.3% invaded the submucosa. Lesions larger than 30 mm had advanced histology (P = 0.001. The primary treatment was endoscopic resection, and invasive carcinoma was referred to surgery. Recurrence rate was 10.6%. Conclusions Large colorectal neoplasms showed a low rate of malignancy. Endoscopic treatment is an effective therapy for these lesions.

    CHINA's first HIV positive diagnosis was in 1985, the victim an ArgentineAmerican. At that time most Chinese,medical workers included, thought of AIDS as a phenomenon occurring outside of China. Twenty years later, the number of HIV/AIDS patients has risen alarmingly. In 2003, the Chinese Ministry of Health launched an AIDS Epidemiological Investigation across China with the support of the WHO and UN AIDS Program. Its results show that there are currently 840,000 HIV carriers, including 80,000 people with full-blown AIDS, in 31 Chinese provinces, municipalities and autonomous regions. This means China has the second highest number of HIV/AIDS cases in Asia and 14th highest in the world. Statistics from the Chinese Venereal Disease and AIDS Prevention Association indicate that the majority of Chinese HIV carriers are young to middle aged, more than half of them between the ages of 20 and 29.

    Full Text Available This work is aimed at identifying factors associated with primary jejunum-ileal tumors malignancy, defining a prediction model with sensitivity, specificity and accuracy to distinguish malign from benign neoplasms. These tumors are rare, have highly unspecific presentation and, frequently, are diagnosed late. We reviewed the charts of 42 patients with primary jejunum-ileal tumors treated in the Department of General Surgery of Rio de Janeiro State University Hospital, Rio de Janeiro, RJ, Brazil, from 1969 to 1998. We performed bivariate analyses, based on chi² test, searching associations between tumors malignancy and demographic and clinical variables. Then logistic regression was employed to consider the independent effect of variables previously identified on malignancy risk. The malign tumors included 11 adenocarcinomas, 7 leiomyosarcomas, 5 carcinoids and 4 lymphomas; the benign tumors included 10 leiomyomas, 2 hamartomas, and single cases of adenoma, multiple neurilemoma and choristoma. The bivariate analyses indicated the association between malignancy and palpable abdominal mass (P = 0.003, period from signs and symptoms onset to diagnosis (P = 0.016, anemia (P = 0.020, anorexia (P = 0.003, abdominal pain (P = 0.031, weight loss (P = 0.001, nausea and vomit (P = 0.094, and intestinal obstruction (P = 0.066; no association with patients demographic characteristics were found. In the final logistic regression model, weight loss, anemia and intestinal obstruction were statistically associated with the dependent variable of interest. Based only on three variables -- weight loss, anemia and intestinal obstruction -- the model defined was able to predict primary jejunum-ileal tumors malignancy with sensitivity of 85.2%, specificity of 80.0%, and accuracy of 83.3%.

    Full Text Available Malignant mesothelioma is a rare malignancy of the body cavities with dismal prognosis. It has been a diagnostic dilemma for years with many clinical and pathological mimics. Discovery of a reliable tumour marker will definitely be of value in screening individuals with a history of asbestos exposure, diagnosis, treatment and follow up of malignant mesothelioma. Many tumour markers have been studied and speculatively associated with the malignant mesothelioma, but much still needs to be proven.

    Full Text Available In the Indonesia Demographic Health Survey 1994 ever married women age 15-49 years were asked whether they have ever heard of AIDS and if so their sources of information concerning prevention and treatment of the disease, and their personal perception about the risk of getting the disease. Half of the women age 20-34 years have ever heard about AIDS and among the older women less than half of them have ever heard about it. This analysis describes information about the relationship between knowledge of ever married women 15-49 years about AIDS with various background characteristics - age, education, occupation, exposure to mass media, area, and regions. This information is required to improve the existing health education campaign about AIDS.   The results indicate that women with less than secondary education or married to husband with less than secondary education or women who do not work or working as farmers are less likely to have ever heard about AIDS. Women who are not exposed to any type of mass media or exposed to only one media are less likely to have ever heard about AIDS than those who are exposed to two or more media. The proportion of women who have ever heard about AIDS in outer Java Bali region is lower than in Java Bali region, likewise in the rural areas it is lower than in urban areas. There are significant associations between area, region, women' education, husbands' education, occupation, exposure to mass media and having ever heart about AIDS. The major source of information about AIDS are from TV and second are newspapers and radio. To control the transmission of HIV/ AIDS the role of mass media is very important and therefore it is necessary to improve the coverage and acceptability of the information considering mothers' education, region/area, and occupation. The information material should be simple and easily understood by the various social levels of community.

    Objective To review the recent studies about microRNAs and advances in malignant lymphoproliferative disorders.Data sources Published articles (2001-2006) about microRNAs and malignant iymphoproliferative disorders were selected using MEDLINE.Study selection After independent review by two observers, 43 of 421 originally identified articles were selected that specifically addressed the stated purpose.Results Two observers independently assessed studies using explicit methodological criteria for evaluating microRNAs in malignant lymphoproliferative disorders. Recent work has revealed a class of small noncoding RNA species,microRNAs, which affect various biological processes. MicroRNAs inhibit the expression of protein encoding genes at the posttranscriptional level in a variety of eukaryotic organisms. In this review, we focused on the biogenetic pathways of microRNAs (miR-15a, miR-16-1, miR-155, miR-17-92 cluster, miR-142) and discussed the implications for human malignant lymphoproliferative disorders.Conclusions microRNAs are involved in tumorigenesis and mediate gene regulation as a fundamental genetic program at the posttranscriptional level. Further study of microRNAs may lead to novel concepts in the diagnosis and treatment of malignant lymphoproliferative disorders.

    We report the case of a 60-year-old man presenting bilateral progressive proptosis with diplopia, weight loss, tachycardia, nervosity, and stomach pain. These signs seemed at first to favor a diagnosis of Graves'ophthalmopathy. Thyroid tests were negative and the initial orbital CT scan was considered normal. A new radiological investigation 4 months later in our hospital revealed typical hypertrophy of the extraocular muscles compatible with orbital metastasis. The systemic investigations demonstrated a pulmonary tumor, multiple hepatic lesions, and several pigmented nodules of gastric mucosa. The pathology of pulmonary and gastric specimens confirmed the diagnosis of malignant melanoma. The primary lesion remains unknown. The authors discuss the differential diagnoses of orbital metastasis and the radiological characteristics of orbital metastasis in malignant melanoma.

    Constitutively activated oncogenic signaling via genetic mutations such as in the EGFR/PI3K/Akt and Ras/RAF/MEK pathways has been recognized as a major driver for tumorigenesis in most cancers. Recent insights into tumor metabolism have further revealed that oncogenic signaling pathways directly promote metabolic reprogramming to upregulate biosynthesis of lipids, carbohydrates, protein, DNA and RNA, leading to enhanced growth of human tumors. Therefore, targeting cell metabolism has become a novel direction for drug development in oncology. In malignant gliomas, metabolism pathways of glucose, glutamine and lipid are significantly reprogrammed. Moreover, molecular mechanisms causing these metabolic changes are just starting to be unraveled. In this review, we will summarize recent studies revealing critical gene alterations that lead to metabolic changes in malignant gliomas, and also discuss promising therapeutic strategies via targeting the key players in metabolic regulation.

    Neuroleptic malignant syndrome (NMS) is a rare idiosyncratic reaction associated with the use of neuroleptics that has an incidence of 0.02 to 3% among patients taking these drugs. This is a very serious complication with a mortality rate that reaches 10-20%. It is therefore very important to have high clinical suspicion and use appropriate criteria to objectify this clinical picture early, stopping the medication causing the picture and to avoid the subsequent complications as much as possible that would be responsible for both its mortality and sequels. We present that case of an 81-year old woman who was admitted to the Psychiatric Hospitalization Unit (PHU) for a depressive episode with psychotic symptoms who developed a neuroleptic malignant syndrome (NMS) when Haloperidol was introduced. After its suspension and subsequent clinical recovery, antipsychotic treatment with Risperidone was reintroduced and she suffered a recurrence of NMS. Finally, significant improvement was achieved with several sessions of electroshock therapy (EST).

    The very rare benign chondroblastoma occasionally invades soft tissues and may grow beyond the epiphysis into the metaphysis. In the present case such a tumour did not show the typical radiological appearances, but presented malignant features both on plain films and on the angiogram. The importance of biopsy of tumours which cannot be identified with certainty must be stressed before radical surgery is carried out.

    Endobronchial metastases (EBM) from extrapulmonary malignant tumors are rare. The most common extrathoracic malignancies associated with EBM are breast, renal and colorectal carcinomas. In this study, we aimed to evaluate the clinical, radiographic and bronchoscopic aspects of patients with EBM who were diagnosed between 1992 and 2002. Data about patients' clinical conditions, symptoms, radiographic and endoscopic findings, and histopathological examination results were investigated. EBM was defined as bronchoscopically visible lesions histopathologically identical to the primary tumor in patients with extrapulmonary malignancies. We found 15 cases with EBM. Primary tumors included breast (3), colorectal (3), and renal (2) carcinomas; Malignant Melanoma (2); synovial sarcoma (1), ampulla of Vater adenocarcinoma (1), pheochromocytoma (1), hypernephroma (1), and Hodgkin's Disease (1). The most common symptoms were dyspnea (80%), cough (66.6%) and hemoptysis (33.3%). Multiple (40%) or single (13.3%) pulmonary nodules, mediastinal or hilar lymphadenopathy (40%), and effusion (40%) were the most common radiographic findings. The mean interval from initial diagnosis to diagnosis of EBM was 32.8 months (range, 0-96 months) and median survival time was 18 months (range, 4-84). As a conclusion, various extrapulmonary tumors can metastasize to the bronchus. Symptoms and radiographic findings are similar with those in primary lung cancer. Therefore, EBM should be discriminated from primary lung cancer histopathologically. Although mean survival time is usually short, long-term survivors were reported. Consequently, treatment must be planned according to the histology of the primary tumor, evidence of metastasis to other sites and medical status of the patient.

  16. Targeting hedgehog in hematologic malignancy.

    Irvine, David A; Copland, Mhairi

    2012-03-08

    The Hedgehog pathway is a critical mediator of embryonic patterning and organ development, including hematopoiesis. It influences stem cell fate, differentiation, proliferation, and apoptosis in responsive tissues. In adult organisms, hedgehog pathway activity is required for aspects of tissue maintenance and regeneration; however, there is increasing awareness that abnormal hedgehog signaling is associated with malignancy. Hedgehog signaling is critical for early hematopoietic development, but there is controversy over its role in normal hematopoiesis in adult organisms where it may be dispensable. Conversely, hedgehog signaling appears to be an important survival and proliferation signal for a spectrum of hematologic malignancies. Furthermore, hedgehog signaling may be critical for the maintenance and expansion of leukemic stem cells and therefore provides a possible mechanism to selectively target these primitive cell subpopulations, which are resistant to conventional chemotherapy. Indeed, phase 1 clinical trials of hedgehog pathway inhibitors are currently underway to test this hypothesis in myeloid leukemias. This review covers: (1) the hedgehog pathway and its role in normal and malignant hematopoiesis, (2) the recent development of clinical grade small molecule inhibitors of the pathway, and (3) the potential utility of hedgehog pathway inhibition as a therapeutic strategy in hemato-oncology.

    As B cells engage in the immune response they express the deaminase AID to initiate the hypermutation and recombination of immunoglobulin genes, which are crucial processes for the efficient recognition and disposal of pathogens, However, AID must be tightly controlled in B cells to minimize off-targeting mutations, which can drive chromosomal translocations and the development of B cell malignancies, such as lymphomas. Recent genomic and biochemical analyses have begun to unravel the crucial question of how AID-mediated deamination is targeted outside immunoglobulin genes. Here, we discuss the transcriptional and topological features that are emerging as key drivers of AID promiscuous activity. PMID:26898111

    The signal processing and fitting methods used for hearing aids have mainly been designed to optimize the intelligibility of speech. Little attention has been paid to the effectiveness of hearing aids for listening to music. Perhaps as a consequence, many hearing-aid users complain that they are not satisfied with their hearing aids when listening to music. This issue inspired the Internet-based survey presented here. The survey was designed to identify the nature and prevalence of problems associated with listening to live and reproduced music with hearing aids. Responses from 523 hearing-aid users to 21 multiple-choice questions are presented and analyzed, and the relationships between responses to questions regarding music and questions concerned with information about the respondents, their hearing aids, and their hearing loss are described. Large proportions of the respondents reported that they found their hearing aids to be helpful for listening to both live and reproduced music, although less so for the former. The survey also identified problems such as distortion, acoustic feedback, insufficient or excessive gain, unbalanced frequency response, and reduced tone quality. The results indicate that the enjoyment of listening to music with hearing aids could be improved by an increase of the input and output dynamic range, extension of the low-frequency response, and improvement of feedback cancellation and automatic gain control systems.

    Full Text Available Abstract Background HIV infection is reported to be associated with some malignant lymphomas (ML so called AIDS-related lymphomas (ARL, with an aggressive behavior and poor prognosis. The ML frequency, pathogenicity, clinical patterns and possible association with AIDS in Tanzania, are not well documented impeding the development of preventive and therapeutic strategies. Methods Sections of 176 archival formalin-fixed paraffin-embedded biopsies of ML patients at Muhimbili National Hospital (MNH/Muhimbili University of Health and Allied Sciences (MUHAS, Tanzania from 1996–2001 were stained for hematoxylin and eosin and selected (70 cases for expression of pan-leucocytic (CD45, B-cell (CD20, T-cell (CD3, Hodgkin/RS cell (CD30, histiocyte (CD68 and proliferation (Ki-67 antigen markers. Corresponding clinical records were also evaluated. Available sera from 38 ML patients were screened (ELISA for HIV antibodies. Results The proportion of ML out of all diagnosed tumors at MNH during the 6 year period was 4.2% (176/4200 comprising 77.84% non-Hodgkin (NHL including 19.32% Burkitt's (BL and 22.16% Hodgkin's disease (HD. The ML tumors frequency increased from 0.42% (1997 to 0.70% (2001 and 23.7% of tested sera from these patients were HIV positive. The mean age for all ML was 30, age-range 3–91 and peak age was 1–20 years. The male:female ratio was 1.8:1. Supra-diaphragmatic presentation was commonest and histological sub-types were mostly aggressive B-cell lymphomas however, no clear cases of primary effusion lymphoma (PEL and primary central nervous system lymphoma (PCNSL were diagnosed. Conclusion Malignant lymphomas apparently, increased significantly among diagnosed tumors at MNH between 1996 and 2001, predominantly among the young, HIV infected and AIDS patients. The frequent aggressive clinical and histological presentation as well as the dominant B-immunophenotype and the HIV serology indicate a pathogenic association with AIDS. Therefore

    AFP (Oct3/4, TSPY, WT-1). The management of patients with DSD is complex and evaluation of tumor risk is aided by advances in genotyping for Y-chromosomal material not evident in traditional karyotyping. More complete genetic screening for DSD patients should increasingly become the standard of care. Developments in pathologic diagnosis will further challenge our traditional understanding of the oncologic management and surveillance of these patients. Future studies utilizing more advanced histologic examination of gonads will improve our understanding of the true incidences of malignancy in this diverse population.

    Full Text Available This paper reports on the transformation that has occurred in the care of people living with HIV/AIDS in a Toronto Hospice. Casey House opened in the pre-HAART era to care exclusively for people with HIV/AIDS, an incurable disease. At the time, all patients were admitted for palliative care and all deaths were due to AIDS-defining conditions. AIDS-defining malignancies accounted for 22 percent of deaths, mainly, Kaposi sarcoma and lymphoma. In the post-HAART era, AIDS-defining malignancies dropped dramatically and non-AIDS-defining malignancies became a significant cause of death, including liver cancer, lung cancer and gastric cancers. In the post-HAART era, people living with HIV/AIDS served at Casey House have changed considerably, with increasing numbers of patients facing homelessness and mental health issues, including substance use. Casey House offers a picture of the evolving epidemic and provides insight into changes and improvements made in the care of these patients.

Accordingly, the AIDS epidemic in India continues to evolve, with the spread of HIV infection in many parts of India already reaching epidemic proportions. The long incubation period between HIV infection and the onset of AIDS, however, means that the majority of infected adults will come down with AIDS in the mid-1990s. AIDS in India will have significant adverse economic effects upon the country. Once ill with opportunistic infections as a result of HIV infection, people will require treatment. The costs of such treatment will strain resources. High levels of AIDS morbidity and mortality among individuals in their most productive years will also reduce the overall productive contributions of society to economic development. The extent of the HIV/AIDS problem in India needs to be accurately assessed, then followed by the implementation of appropriate prevention and care programs. The situation will not be able to reversed if responsible parties act only after the existence of HIV/AIDS becomes evident in large numbers of people. Policymakers and program planners working against the spread of HIV throughout India will be called upon to strike and maintain a balance in the allocation of resources for treatment and prevention. They will have to be realistic, yet humanistic, while considering individual rights in the context of more broad social welfare. The authors explain that it is cheaper to prevent AIDS than to treat and manage it, and that urgent measures are needed to protect the productive base of the economy. Sections discuss the role of epidemiology, the spread of HIV through infected needles and syringes, AIDS and HIV in Maharashtra, and the economics of AIDS.

    Forty-five life insurance companies responded to a questionnaire on insurance industry attitudes towards patients with a history of malignancy other than skin carcinoma. Although the criteria for acceptance, provisions of the policy, and philosophy about adjuvant treatment varied, all companies would underwrite such patients provided that at application there was no evidence of persistent or recurrent disease or severe complications of therapy. The concept of excess mortality (observed death rates versus standard expected death rates) is used with other factors in calculating premiums. Legal and ethical responsibilities of physicians associated with insurance applications are briefly discussed.

    Full Text Available BACKGROUND: Colorectal cancer is the most common cancer in men and in women worldwide. Incidence rates of colorectal cancer vary 10 - fold in both sexes worldwide, Within Asia, the incidence rates vary widely and are uniformly low in all south Asian countries and high i n all developed Asian countries. Fortunately, the age adjusted incidence rates of colorectal cancer in all the Indian cancer registries are very close to the lowest rates in the world. The present study is under taken to study the prevalence and types of c olorectal cancer among the patients in the rural population in and around Chidambaram. OBJECTIVES: To study the prevalence of malignant colorectal neoplasms among the speci mens received in the Department of Pathology and the gross and histomorphological pa ttern of the lesions and finally to correlate the findings with clinical data. METHOD: The materials consisted of 68 specimens who were submitted to the Department of Pathology, during the period of Jan 2008 - Dec 2012. Data collected and entered in MS - Excel and were analyzed using SPSS - 16. RESULTS : Out of 8454 colonoscopic specimens, 68(0.8% showed colorectal malignancy. A higher frequency of colorectal was seen in 6 th decade.

    The working memory plays an important role in successfully overcoming adverse listening conditions and should consequently be considered when designing and testing hearing aids. A number of studies have established the relationship between hearing in noise and working memory involvement, but with the Sentence-final Word Identification and Recall (SWIRL) test, it is possible to show that working memory is also involved in listening under favorable conditions and that noise reduction has a positive influence in situation with very little noise. Although the capacity of the working memory is a finite individual size, its involvement can differ with fatigue and other factors and individualization of hearing aids should take this into account to obtain the best performance. A way of individually adapting hearing aids is based on changes in the electrical activity of the brain (EEG). Here we present the possibilities that arise from using EEG and show that ear-mounted electrodes is able to record useful EEG that can be explored for individualization of hearing aids. Such an adaptation could be done based on changes in the electrical activity of the brain (EEG). Here we present the possibilities that arise from using EEG and show that ear-mounted electrodes is able to record useful EEG that can be explored for individualization of hearing aids.

    Full Text Available BACKGROUND: HIV-related opportunistic infections (OIs and malignancies continued to cause morbidity and mortality in Chinese HIV-infected individuals. The objective for this study is to elucidate the prevalence and spectrums of OIs and malignancies in HIV-infected patients in the Beijing Ditan Hospital. METHODS: The evaluation of the prevalence and spectrums of OIs and malignancies was conducted by using the clinical data of 834 HIV-infected patients admitted in the Beijing Ditan hospital from January 1, 2009, to November 30, 2012. RESULTS: The prevalence and spectrums of OIs and malignancies varied contingent on geographic region, transmission routes, and CD4 levels. We found that tuberculosis was most common OI and prevalence was 32.5%, followed by candidiasis(29.3%, Pneumocystis pneumonia(PCP(22.4%, cytomegalovirus(CMV infection(21.7%, other fungal infections(16.2%, mycobacterium avium complex(MAC(11.3%, cryptococcosis(8.0%, progressive multifocal leukoencephalopathy(PML(4.4%, Cerebral Toxoplasmosis(3.5% and Penicillium marneffei infection(1.4%; while Lymphoma(2.9%, Kaposi's sarcoma(0.8% and cervix carcinoma(0.3% were emerged as common AIDS-defining malignancies. Pulmonary OI infections were the most prevalent morbidity and mortality in patients in the AIDS stage including pulmonary tuberculosis (26.6% and PCP (22.4%.

    2010-01-01

    Full Text Available Background and Objectives: In vivo stains are prompt resources, which have emerged, in the recent years, to aid as clinical diagnostic tools in detecting early premalignant and malignant lesions. The aim of the study was to determine the diagnostic efficiency of toluidine blue with Lugol′s iodine in oral premalignancies and malignancies and to evaluate the reliability of in vivo staining with toluidine blue and Lugol′s iodine in the lesions at risk of malignancy. Materials and Methods: The study group comprised 30 subjects with clinically suspicious premalignant lesions and 30 subjects with clinically suspicious malignant lesions. All the lesions were stained consecutively with toluidine blue and Lugol′s iodine and the dye retention were recorded with photographs. Depending on the retention of the dyes, the biopsy site was determined. The biopsy specimens were sent for histological confirmation and results were statistically analyzed. Results: The overall diagnostic accuracy of Lugol′s iodine when used consecutively with toluidine blue stain in distinguishing premalignant lesions and malignant lesions was 90%. As the degree of differentiation of malignant lesions progressed toward more severity, they failed to show the retention of Lugol′s iodine and the result was highly significant statistically, with a P value < 0.001. Interpretation and Conclusion: Lugol′s iodine when used with toluidine blue helped in delineating the inflammatory lesions and was the mean source in determining clinically the degrees of differentiation of malignant lesions as the poorly differentiated malignant lesions without glycogen content failed to show Lugol′s iodine retention. Toluidine blue with Lugol′s iodine can be used as a pretherapeutic assessment of the biologic aggressiveness of the disease.

    2011-12-01

    Full Text Available Considering that there are some studies with autopsies from AIDS describing only malignant neoplasias and that changes can occur after the introduction of Highly Active Antiretroviral Therapy (HAART, our objectives were to analyze the frequency of benign and malignant neoplasms in AIDS patients in the periods of both pre- and post-HAART. This is a retrospective study with 261 autopsies of HIV-positive patients between 1989 and 2008 in Uberaba, Brazil. Sixty-six neoplasms were found (39 benign, 21 malignant and six premalignant in 58 patients. The most frequent malignant neoplasms were lymphoid, in 2.7% (four Non-Hodgkin lymphoma, one Hodgkin, one multiple myeloma and one plasmablastic plasmacytoma, and Kaposi's Sarcoma, in 2.3% (six cases. The most frequent benign neoplasms were hepatic hemangiomas in 11 (4.2% of 261 cases and uterine leiomyoma in 11 (15.7% of 70 woman. In the pre-HAART period eight (9.8% benign neoplasias and four (4.9% malignant occurred in 82 patients; in the post-HAART period, 29 (16.2% benign and 17 (9.5% malignant were present; however, the differences were not significant. We conclude that the introduction of HAART in our region doesn't look to have modified the frequency of neoplasms occurring in patients with HIV.

    The Ministry of Health coordinates and orients in Brazil all the activities concerning the acquired immunodeficiency syndrome which is officially designated as AIDS. The first AIDS' case registered in Brazil was, by retrospective diagnosis, in 1981 but it was in 1982 that the first two diagnosis in live patients were made. The incidence is very high in this country that is among the ones where the higher number of cases are being registered. The great majority of the Brazilian cases occurs in the cities and in direct proportion to the population index. The groups of risk are the same universally known and a comparative increase of heterosexual transmission is noted, chiefly due to the use of injectable drugs and bisexuality of the male partners. Another problem that is being increased is pediatric AIDS, with raising importance of perinatal transmission as well as the use of injectable drugs and precocious prostitution in adolescence. The transfusional and haemophilic AIDS have proportionally decreased due to the control of blood products. The control and the orientation activity of the Ministry of Health is directed to varied points such as: compulsory cases notification, cooperation between public and private sectors, preventive and sexual orientation, freely delivered medication and laboratory tests including sigilous tests, lay and technical personnel preparation, diversified informative and educational campaigns. Trial tests with anti-HIV vaccines have begun to be performed. Multiple Reference Centers were officially established by the administration. Among them is to be quoted the Hospital Universitário Gaffrée Guinle of Rio de Janeiro where the authors work. It is credited for its intensive activity and pioneerism. In this Institution special attention was due against discrimination of HIV-infected patients, to diagnosis, to anonymous and sigilous tests, to medical and psychological assistance, to myocardium involvement, to the virologic study of the

  8. Political dimensions of AIDS.

    Blewett, N

    World political aspects and the example of Australia as a national political response to AIDS are presented. Global policy on AIDS is influenced by the fact that the AIDS epidemic is the 1st to be largely predictable, that long lag times occur between intervention and measurable events, and by the prompt, professional leadership of WHO, lead by Dr. J. Mann. WHO began a Global Programme on AIDS in 1987, modelled on the responses of Canada and Australia. A world summit of Ministers of Health was convened in January 1988. These moves generated a response qualified by openness, cooperation, hope and common sense. The AIDS epidemic calls for unprecedented involvement of politicians: they must coordinate medical knowledge with community action, deal with public fear, exert strong, rational leadership and avoid quick, appealing counterproductive responses. 3 clear directions must be taken to deal with the epidemic: 1) strong research and education campaigns; 2) close contact with political colleagues, interest groups and the community; 3) a national strategy which enjoins diverse interest groups, with courage, rationality and compassion. In Australia, the AIDS response began with the unwitting infection of 3 infants by blood transfusion. A public information campaign emphasizing a penetrating TV ad campaign was instituted in 1987. Policy discussions were held in all parliamentary bodies. The AIDS epidemic demands rapid, creative responses, a break from traditions in health bureaucracy, continual scrutiny of funding procedures and administrative arrangements. In practical terms in Australia, this meant establishing a special AIDS branch within the Health Advancement Division of the Community Health Department. AIDS issues must remain depoliticized to defuse adversary politics and keep leaders in a united front.

    Computed tomography (CT) findings were assessed in 7 patients with malignant mesothelioma. CT findings were also reviewed in 9 patients with lung cancer and pleuritis carcinomatosa and in 11 patients with tuberculous pleuritis. Five patients with malignant mesothelioma underwent CT scans twice, on admission and from 1 to 7 months after admission. Tuberculous pleuritis could be distinguished from pleuritis carcinomatosa and malignant mesothelioma by the presence or absence of pleural nodularity and chest wall invasion. Although it was difficult to identify specific CT features clearly distinguishing malignant mesothelioma from pleuritis carcinomatosa, characteristic findings of malignant mesothelioma appeared to include the rapid development and progression of pleural rind and a tendency to spread directly into the chest wall. We divided the pleural into the four regions; upper anterior, upper posterior, lower anterior and lower posterior regions. Pleural changes were more frequently seen in the lower pleural regions than in the upper pleural regions in malignant mesothelioma. (author).

    Full Text Available Daniel Schneiderbanger, Stephan Johannsen, Norbert Roewer, Frank SchusterDepartment of Anaesthesia and Critical Care, University of Wuerzburg, Wuerzburg, GermanyAbstract: Malignant hyperthermia is a potentially lethal inherited disorder characterized by disturbance of calcium homeostasis in skeletal muscle. Volatile anesthetics and/or the depolarizing muscle relaxant succinylcholine may induce this hypermetabolic muscular syndrome due to uncontrolled sarcoplasmic calcium release via functionally altered calcium release receptors, resulting in hypoxemia, hypercapnia, tachycardia, muscular rigidity, acidosis, hyperkalemia, and hyperthermia in susceptible individuals. Since the clinical presentation of malignant hyperthermia is highly variable, survival of affected patients depends largely on early recognition of the symptoms characteristic of malignant hyperthermia, and immediate action on the part of the attending anesthesiologist. Clinical symptoms of malignant hyperthermia, diagnostic criteria, and current therapeutic guidelines, as well as adequate management of anesthesia in patients susceptible to malignant hyperthermia, are discussed in this review.Keywords: malignant hyperthermia, volatile anesthetics, succinylcholine, in vitro contracture test, genetics

    Konotey-Ahulu, F I

    1987-07-25

    Relying on his tour of 16 sub-Saharan countries, the author judges the extent of acquired immunodeficiency syndrome (AIDS) in Africa on a scale from grade I (not much of a problem) to grade V (a catastrophe). In his assessment, AIDS is a problem (grade II) in only 5, possibly 6, countries where it has occurred. In no country is the AIDS problem consistently grade III (a great problem), nor ever grade IV (an extremely great problem), and in none can it be called a catastrophe (grade V). In Kenya, for instance, contrary to widespread rumors, the author rates AIDS in 1987 as grade I. Journalistic hyperbole has proved very expensive in that Africans overseas have experienced racial abuse and tourism has unjustly suffered. Tension seems to have developed between white doctors working in Africa, with externally funded research in danger of being halted in several countries.

  12. An Automatic System to Discriminate Malignant from Benign Massive Lesions on Mammograms

    2007-01-01

    Mammography is widely recognized as the most reliable technique for early detection of breast cancers. Automated or semi-automated computerized classification schemes can be very useful in assisting radiologists with a second opinion about the visual diagnosis of breast lesions, thus leading to a reduction in the number of unnecessary biopsies. We present a computer-aided diagnosis (CADi) system for the characterization of massive lesions in mammograms, whose aim is to distinguish malignant from benign masses. The CADi system we realized is based on a three-stage algorithm: a) a segmentation technique extracts the contours of the massive lesion from the image; b) sixteen features based on size and shape of the lesion are computed; c) a neural classifier merges the features into an estimated likelihood of malignancy. A dataset of 226 massive lesions (109 malignant and 117 benign) has been used in this study. The system performances have been evaluated terms of the receiver-operating characteristic (ROC) analys...

  13. Oncolytic Virotherapy for Hematological Malignancies

    2012-01-01

    Full Text Available Hematological malignancies such as leukemias, lymphomas, multiple myeloma (MM, and the myelodysplastic syndromes (MDSs primarily affect adults and are difficult to treat. For high-risk disease, hematopoietic stem cell transplant (HCT can be used. However, in the setting of autologous HCT, relapse due to contamination of the autograft with cancer cells remains a major challenge. Ex vivo manipulations of the autograft to purge cancer cells using chemotherapies and toxins have been attempted. Because these past strategies lack specificity for malignant cells and often impair the normal hematopoietic stem and progenitor cells, prior efforts to ex vivo purge autografts have resulted in prolonged cytopenias and graft failure. The ideal ex vivo purging agent would selectively target the contaminating cancer cells while spare normal stem and progenitor cells and would be applied quickly without toxicities to the recipient. One agent which meets these criteria is oncolytic viruses. This paper details experimental progress with reovirus, myxoma virus, measles virus, vesicular stomatitis virus, coxsackievirus, and vaccinia virus as well as requirements for translation of these results to the clinic.

  14. Stents for malignant ureteral obstruction

    2016-07-01

    Full Text Available Malignant ureteral obstruction can result in renal dysfunction or urosepsis and can limit the physician's ability to treat the underlying cancer. There are multiple methods to deal with ureteral obstruction including regular polymeric double J stents (DJS, tandem DJS, nephrostomy tubes, and then more specialized products such as solid metal stents (e.g., Resonance Stent, Cook Medical and polyurethane stents reinforced with nickel-titanium (e.g., UVENTA stents, TaeWoong Medical. In patients who require long-term stenting, a nephrostomy tube could be transformed subcutaneously into an extra-anatomic stent that is then inserted into the bladder subcutaneously. We outline the most recent developments published since 2012 and report on identifiable risk factors that predict for failure of urinary drainage. These failures are typically a sign of cancer progression and the natural history of the disease rather than the individual type of drainage device. Factors that were identified to predict drainage failure included low serum albumin, bilateral hydronephrosis, elevated C-reactive protein, and the presence of pleural effusion. Head-to-head studies show that metal stents are superior to polymeric DJS in terms of maintaining patency. Discussions with the patient should take into consideration the frequency that exchanges will be needed, the need for externalized hardware (with nephrostomy tubes, or severe urinary symptoms in the case of internal DJS. This review will highlight the current state of diversions in the setting of malignant ureteral obstruction.

    Some recent literature in the meta-analysis category where results from a range of studies are brought together throws doubt on the ability of foreign aid to foster economic growth and development. This paper assesses what meta-analysis has to say about the effectiveness of foreign aid in terms...... of the growth impact. We re-examine key hypotheses, and find that the effect of aid on growth is positive and statistically significant. This significant effect is genuine, and not an artefact of publication selection. We also show why our results differ from those published elsewhere....

    Fifty-two patients with pulmonary complications of acquired immunodeficiency syndrome (AIDS) were studied over a 3-year period. The vast majority of the patients were homosexual; however, a significant number were intravenous drug abusers. Thirteen different organisms were noted, of which Pneumocystis carinii was by far the most common. Five patients had neoplasia. Most patients had initial abnormal chest films; however, eight patients subsequently shown to have Pneumocystis carinii pneumonia had normal chest films. A significant overlap in chest radiographic findings was noted among patients with different or multiple organisms. Lung biopsy should be an early consideration for all patients with a clinical history consistent with the pulmonary complications of AIDS. Of the 52 patients, 41 had died by the time this report was completed.

  20. Investigation of Diarrhea in AIDS

    Full Text Available Chronic diarrhea is a common problem in patients with acquired immune deficiency syndrome (AIDS, resulting in significant morbidity and potential mortality. In the early stages of immunodeficiency, human immunodeficiency virus (HIV-infected patients are susceptible to infection with the same enteric pathogens that cause diarrhea in immunocompetent hosts, but with progressive immunodeficiency, these patients become susceptible to numerous opportunistic disorders. The main factor to consider when tailoring the work-up of diarrhea in the HIV-infected patient is the immune status, which is reflected by the total CD4 lymphocyte cell count. A CD4 count of less than 100 cells/µL is significantly correlated with opportunistic disorders. For the HIV-infected patient with diarrhea, repeated stool studies to investigate for bacteria, ova and parasites should be the first step. When either upper or lower gastrointestinal tract symptoms are present and stool studies are negative, endoscopy directed to the probable organ of involvement is appropriate. If localizing symptoms are absent, the most appropriate next test is sigmoidoscopy with biopsies. Not infrequently, despite extensive evaluation, the cause of diarrhea in patients with AIDS remains unexplained. Recently, the widespread use of highly active antiretroviral therapy, including protease inhibitors, has led to a change in the epidemiology of diarrhea in AIDS patients. As their immune status improves, HIV-infected patients treated with combination therapy become less prone to opportunistic disorders. However, diarrhea appears to be frequent because several antiretroviral agents can themselves cause diarrhea.

    Chemotherapy represents the most important therapeutic option in malignant lymphomas. Low to intermediate risk Hodgkin's disease is treated by a combination of chemotherapy and radiation. The new chemotherapy protocol BEACOPP has improved the outcome of advanced stages in comparison with the internationally accepted standard protocol COPP/ABVD. Dependent on the initial staging, cure rates between 50 and 95% can be achieved. Indolent non-Hodgkin's lymphomas usually present in advanced stages of disease. Chemotherapy in these cases has palliative character and aims at improving patients'quality of life and at avoiding complications due to the disease. In aggressive and very aggressive non-Hodgkin's lymphoma chemotherapy is curative and must be initiated immediately irrespective of the staging results. The efficacy of the standard protocol CHOP (cyclophosphamide,doxorubicin, vincristine and prednisone), that was established in the 1970s, has recently been improved by shortening of the therapy interval (CHOP-14 vs.CHOP-21),addition of etoposide (CHOEP) and combination with the monoclonal antibody rituximab (R-CHOP). The value of high dose chemotherapy with stem cell transplantation has been shown unequivocally only for aggressive non-Hodgkin lymphoma and relapsed Hodgkin's disease responsive to chemotherapy. The therapeutic strategy of malignant lymphomas is likely to be improved within the next years due to the introduction of novel cytostatic agents, the broadening application of monoclonal antibodies,upcoming new transplantation procedures and the development of substances with molecular targets.To rapidly increase our current knowledge on the topic it is mandatory to include patients into the large national and international multicenter studies.

    Antipsychotic drugs are widely and increasingly prescribed for neurobehavioral disorders in elderly patients. However, the efficacy of these drugs has not been consistently demonstrated in geriatric populations and there are continuing concerns regarding adverse effects. Among the latter are severe neurological disorders, including neuroleptic malignant syndrome. Although the incidence and mortality of neuroleptic malignant syndrome may have declined with heightened awareness of this disorder and the development of newer drugs, neuroleptic malignant syndrome still occurs in association with the use of antipsychotics. To enhance patient safety and clinical vigilance among practitioners, the authors present a clinical overview of neuroleptic malignant syndrome.

    Full Text Available Malignant melanoma is a malignant neoplasia drives from melanocytes. Malignant melanoma, the most causing death, is seen in the third place at skin cancer. Malignant melanoma shows intrinsic resistance to chemotherapeutic agents and variability in the course of the disease which are distinct features separating from other solid tumors. These features prevent the development and standardization of non-surgical treatment models of malignant melanoma. Although there is a large number of chemotherapeutic agents used in the treatment of metastatic malignant melanoma, it hasn’t been demonstrated the survival advantage of adjuvant treatment with chemotherapeutic agents. Because of the different clinical course of malignant melanoma, the disease is thought to be closely associated with immune system. Therefore, immunomodulatory therapy models were developed. Mistletoe stimulates the immune system by increasing the number and activity of dendritic cells, thus it has been shown to effect on tumor growth and metastasis of malignant melanoma patient. Outlined in this review are the recent developments in the understanding the role of mistletoe as a complementary therapy for malignant melanoma. J Clin Exp Invest 2014; 5 (1: 145-152

    Ductal adenocarcinoma is the most common malignant tumor of the pancreas. Despite great efforts in basic and clinical pancreatic cancer research, the prognosis remains poor with an overall 5-year survival rate of less than 5%. Complete surgical resection represents the only curative treatment option and 5-year survival rates of 20-25% can be achieved following curative resection and adjuvant chemotherapy. Although pancreatic surgery is considered one of the most technically demanding and challenging procedures, there has been constant progress in surgical techniques and advances in perioperative care with a modern interdisciplinary approach including anesthesiology, oncology, radiology and nursing. This has reduced morbidity and especially mortality rates in high-volume centers. Among extended resection procedures multivisceral and venous resections are technically feasible and should be considered if a complete tumor resection can be achieved. Multimodal regimens have shown promising results, however, only adjuvant chemotherapy is supported by solid evidence from randomized controlled trials. (orig.) [German] Das duktale Adenokarzinom ist der haeufigste maligne Pankreastumor. Trotz intensiver Anstrengungen auf dem Gebiet der Pankreasforschung konnte die Gesamtprognose in den vergangenen Jahren nicht entscheidend verbessert werden. Die einzige potenziell kurative Therapie ist die chirurgische Resektion. In Kombination mit einer adjuvanten Chemotherapie liegen die 5-Jahres-Ueberlebensraten aktuell bei 20-25%. Dank kontinuierlicher Weiterentwicklung der chirurgischen Operationstechnik und Verbesserungen der perioperativen Versorgung der Patienten mit einer engen interdisziplinaeren Zusammenarbeit (Chirurgie, Anaesthesie, Onkologie, Radiologie und Pflege) konnten die perioperative Morbiditaets- und Mortalitaetsraten in den vergangenen Jahren deutlich gesenkt werden.

    Full Text Available HIV infection and AIDS is increasingly becoming a major public health problem in our country. Currently, the reported cases represent only the 'tip of the iceberg' of the problem. In view of the fact that no cure or vaccine for the disease has yet been found, spreading knowledge and removing misconceptions is about the only way that AIDS can be effectively tackled.This handbook, developed by Prof. Shankar Chowdhury and associates, seeks to address all levels of medical and non-medical AIDS workers, as well as the layman. It deals with topics ranging from biology of the virus, symptoms and transmission of disease, to prevention, counselling for infected persons and action plan for AIDS education.The biology of the virus and the immune system is described in simple terms, as well as methods of testing for HIV, and what these test results mean. The progression of disease in adults and children, development of symptoms, diagnostic criteria for AIDS, treatment and outcome of disease is dealt with. How AIDS spreads between people, and the health risk for health workers and families is examined. The various ways in which transmission of HIV can be prevented is looked at in detail, including public health measures, national and internatonal action, and ethical and human rights issues involved.

    The central research problem of this project is the effective representation and display of surfaces, interpolating to given information, in three or more dimensions. In a typical problem, we wish to create a surface from some discrete information. If this information is itself on another surface, the problem is to determine a surface defined on a surface,'' which is discussed below. Often, properties of an already constructed surface are desired: such geometry processing'' is described below. The Summary of Proposed Research from our original proposal describes the aims of this research project. This Summary and the Table of Contents from the original proposal are enclosed as an Appendix to this Progress Report. The broad sweep from constructive mathematics through algorithms and computer graphics displays is utilized in the research. The wide range of activity, directed in both theory and applications, makes this project unique. Last month in the first Ardent Titan delivered in the State of Arizona came to our group, funded by the DOE and Arizona State University. Although the Titan is a commercial product, its newness requires our close collaboration with Ardent to maximize results. During the past year, four faculty members and several graduate research assistants have worked on this DOE project. The gaining of new professionals is an important aspect of this project. A listing of the students and their topics is given in the Appendix. The most significant publication during the past year is the book, Curves and Surfaces for Computer Aided Geometric Design, by Dr. Gerald Farin. This 300 page volume helps fill a considerable gap in the subject and includes many new results on Bernstein-Bezier curves and surfaces.

    Full Text Available INTRODUCTION: Gastrointestinal malignancies are one of the most common malignancies encountered frequently, with rising incidence in young age due to the changing lifestyle and food habits in India. Oesophagus, stomach and colonic cancers are the commonly affected regions of the GI tract. These malignancies is known to occur in older age of fifth decade onwards. This is a study intended to highlight the rising incidence of such malignancies in the younger age in second to third decade as observed in and around Mangalore. Upper gastrointestinal malignancies are common in oesophagus and stomach, whereas lower gastrointestinal malignancies occur more commonly seen in colon. Colorectal cancer (CRC is one of the most common of all familial malignancies with peak incidence in 60 to 70 years of age, 90% of cases occur in people aged 50 or older.Risk factors include a genetic predisposition, diet and lifestyle changes in the current era. Inheritance plays a role in the pathogenesis of upto a third of CRC cases. AIMS AND OBJECTIVE: To study the prevalence of gastrointestinal malignancies in patients less than fifty years and the association of positive family history and polyps with colorectal carcinomas. MATERIAL AND METHODS: This is a retrospective study of 128 cases of gastrointestinal malignancies from June 2010 to May 2012 received in and around Mangalore. The study includes endoscopic biopsies, colonoscopic biopsies partial and total colectomy specimens with growth seen anywhere from oesophagus to rectum. Representative sections are taken, processed routinely and stained with H & E. The pathological findings are then correlated with clinical data like age and sex distribution, site, family history and presence of other malignancies. RESULTS: In this study gastrointestinal malignancies were studied as upper and lower gastrointestinal lesions. Upper gastrointestinal (GI lesions were those in oesophagus, stomach, and duodenum.

    Full Text Available During malignant melanoma (MM progression including incipient metastasis, neoplastic cells follow some specific migration paths inside the skin. In particular, they progress along the dermoepidermal basement membrane, the hair follicles, the sweat gland apparatus, nerves, and the near perivascular space. These features evoke the thigmotropism phenomenon defined as a contact-sensing growth of cells. This process is likely connected to modulation in cell tensegrity (control of the cell shape. These specifically located paucicellular aggregates of MM cells do not appear to be involved in the tumorigenic growth phase, but rather they participate in the so-called “accretive” growth model. These MM cell collections are often part of the primary neoplasm, but they may, however, correspond to MM micrometastases and predict further local overt metastasis spread.

    Approximately 10% of patients with malignant lymphoma will show neurological symptoms at some time during the course of their illness. In non-Hodgkin lymphoma, CNS involvement is more frequent than in Hodgkin's disease. Diffuse histiocytic and poorly differentiated lymphomas, bone marrow involvement, advanced tumor stage and hematogenous spread are particular risk factors. Invasion of the spinal canal is the most common type of CNS involvement. Intracranial lesions, which are comparatively rare, may present as intracerebral metastases, epi- or subdural masses or focal or diffuse leptomeningeal disease. Lymphomatous leptomeningitis usually cannot be demonstrated by CT. On the other hand, dural and cerebral parenchymal lesions are sometimes highly characteristic of lymphoma as a result of their features and location.

    The purpose of this review is to underline important advancements in the understanding of cancer risks in systemic lupus erythematosus (SLE). In SLE, there is an increased risk of specific kinds of malignancy. For example, the risk of non-Hodgkin’s lymphoma is increased several-fold in SLE versus the general population. In addition, heightened risks for lung cancer, thyroid cancer and cervical dysplasia in SLE have been found. Some have postulated that immunosuppressive drugs play a role, as well as other important mediators, such as lupus disease activity itself. One new frontier being explored is the significant finding of a decreased risk of certain nonhematologic cancers (e.g., breast, ovarian, endometrial and prostate) in SLE. The reasons for this are currently under study. PMID:19643208

    Full Text Available Malakoplakia is an unusual inflammatory disease with uncertain pathogenesis affecting any organ in the body, but predominantly genitourinary tract, with specific predilection to the bladder. We report a rare case of isolated malakoplakia of the urachus in a 29-year-old male patient who presented with lower urinary tract symptoms without any hematuria. Investigations revealed sterile pyuria with no bacterial growth in urine. Radiological investigations revealed a mass in the urachal region. The patient underwent cystoscopy with biopsy followed by pelvic lymph node dissection and partial cystectomy with excision of the urachal mass. Histopathological examination of the mass revealed malakoplakia. Postoperative course was uneventful. To the best of our knowledge, this is the first ever case report of isolated urachal malakoplakia without any concomitant malignancy or bladder involvement reported in our country and one of the very few reported worldwide.

    The spectrum of complications emerging in successfully treated HIV-infected patients has dramatically changed since the advent of HAART. Typical AIDS-defining illnesses have been substituted by new comorbid conditions that threaten even those patients who maintain virologic suppression. Proper management of cardiovascular risk, and early diagnosis of AIDS-related and, particularly, non-AIDS-related malignancies (including papilomavirus-related neoplasms) must be introduced into the routine of care. Hot areas of investigation include HIV-associated neurocognitive disorders, hepatitis B and C coinfection, non-alcoholic fatty liver disease, progressive multifocal leukoencephalopathy and tuberculosis. Bone and kidney long-term toxicities and lipoatrophy remain as issues of paramount importance. The identification and early treatment of immune reconstitution disease is also of major interest, specially in those patients starting their antiretroviral treatment with severe CD4 cell depletion. The present review focuses on these twelve areas of increasing interest for physicians currently facing successfully treated HIV+ patients.

    Sphingolipids represent a major class of lipids that are essential constituents of eukaryotic cells. They are predominantly located in plasma membrane microdomains, and play an important structural role in regulating membrane fluidity. They are also bioactive effectors involved in diverse key cellular functions such as apoptosis and proliferation. The implication of some sphingolipids in cancer is well established whereas that of some others is still a matter of intense investigation. Glucosylceramide is the backbone of more than 300 structurally different glycosphingolipids including gangliosides and sulfatides, and is essential for mammalian development. Therefore, glucosylceramidases (also named GBA1, GBA2 and GBA3 β-glucosidases), the enzymes that hydrolyse β-glucosylceramide, play important functions. GBA1 is a lysosomal hydrolase whose deficiency causes Gaucher disease, the most prevalent inherited lysosomal storage disorder. GBA2 is a ubiquitous non-lysosomal glucosylceramidase whose mutations have been associated with some forms of hereditary spastic paraplegia. GBA3 is a cytosolic β-glucosidase, mostly present in the kidney, liver, spleen, intestine and lymphocytes of mammals, the function of which is still unclear. Whereas glucosylceramide synthase is implicated in multidrug resistance, the role of glucosylceramide breakdown in cancer is not yet fully appreciated. Defective GBA1 enzyme activity in humans, i.e., Gaucher disease, is associated with an increased risk of multiple myeloma and other malignancies. Putative molecular links between Gaucher disease and cancer, which might implicate the malignant cell and/or its microenvironment, are reviewed. The functions of GBA2 and GBA3 in cancer progression are also discussed.

    Evaluation of abdominal pain requires an understanding of the possible causes(benign or malignant) and recognition of typical patterns and clinical presentation. Abdominal pain has multiple causes; associated signs and symptoms may aid in the diagnosis. Remember that some patients will not have a textbook presentation, and unusual causes for pain must be considered. Those with chronic pancreatitis with structural complications should be operated on early, whereas those with other types of chronic pancreatitis should receive medical therapy focusing on alleviating symptoms. Control of the most troublesome symptoms will provide the best management for IBS. Pharmacologic success in bowel obstruction depends on the level and degree of obstruction. Decision making is based on reasonable expectations of survival, treatment-related success, performance status, and goals of care. Quality of life will be enhanced by appropriate symptom management.

    Dermoscopy is a noninvasive technique that enables visualization of subsurface colors and structures within the skin that are imperceptible to the naked eye. The dermatoscope allows the physician to examine both the macroscopic and microscopic primary morphology of skin lesions, identify subtle clinical clues, confirm naked-eye clinical diagnoses, and monitor treatment progress while posing little threat to the young patient. Dermoscopic findings have been formulated into diagnostic criteria that assist experienced clinicians in differentiating benign and malignant neoplasms. In this review, clinical morphology of melanocytic nevi and melanoma in the pediatric population is examined and the relevant dermoscopic findings and histopathologic correlates that aid in the diagnosis and management of these lesions are described.

    Gynecologic malignancies are a leading cause of death in women worldwide. Standard treatment for many primary and recurrent gynecologic cancer cases includes a combination of external beam radiation, followed by brachytherapy. Magnetic Resonance Imaging (MRI) is benefitial in diagnostic evaluation, in mapping the tumor location to tailor radiation dose, and in monitoring the tumor response to treatment. Initial studies of MR-guidance in gynecologic brachtherapy demonstrate the ability to optimize tumor coverage and reduce radiation dose to normal tissues, resulting in improved outcomes for patients. In this article we describe a methodology to aid applicator placement and treatment planning for 3 Tesla (3T) MR-guided brachytherapy that was developed specifically for gynecologic cancers. This has been used in 18 cases to date in the Advanced Multimodality Image Guided Operating suite at Brigham and Women's Hospital. It is comprised of state of the art methods for MR imaging, image analysis, and treatment plann...

  7. Influence of nuclei segmentation on breast cancer malignancy classification

    2009-02-01

    Breast Cancer is one of the most deadly cancers affecting middle-aged women. Accurate diagnosis and prognosis are crucial to reduce the high death rate. Nowadays there are numerous diagnostic tools for breast cancer diagnosis. In this paper we discuss a role of nuclear segmentation from fine needle aspiration biopsy (FNA) slides and its influence on malignancy classification. Classification of malignancy plays a very important role during the diagnosis process of breast cancer. Out of all cancer diagnostic tools, FNA slides provide the most valuable information about the cancer malignancy grade which helps to choose an appropriate treatment. This process involves assessing numerous nuclear features and therefore precise segmentation of nuclei is very important. In this work we compare three powerful segmentation approaches and test their impact on the classification of breast cancer malignancy. The studied approaches involve level set segmentation, fuzzy c-means segmentation and textural segmentation based on co-occurrence matrix. Segmented nuclei were used to extract nuclear features for malignancy classification. For classification purposes four different classifiers were trained and tested with previously extracted features. The compared classifiers are Multilayer Perceptron (MLP), Self-Organizing Maps (SOM), Principal Component-based Neural Network (PCA) and Support Vector Machines (SVM). The presented results show that level set segmentation yields the best results over the three compared approaches and leads to a good feature extraction with a lowest average error rate of 6.51% over four different classifiers. The best performance was recorded for multilayer perceptron with an error rate of 3.07% using fuzzy c-means segmentation.

    2015-01-01

    As an important feature of financing aid work for university poor students, the moral hazard problem not only determines its success or failure but also highly affects the entire community values and ethical order. The new paradigm of ethical thinking and the pursuit of perfection of responsibility ethics provide remedial mechanism to deal with the moral hazard of financing aid work. Adding the responsibility ethics in the ethics structure of financing aid work for university poor students is an effective way for our response to the challenges of moral hazard for aiding poor students. On the one hand, we need to strengthen the subjects' responsibility ethics education, enhance their ability of responsibility awareness and ability; on the other hand, it is needed to establish the ethical rules and supervision and evaluation mechanism for supporting funding policy to stimulate the subjects to fulfill the spirit of ethical responsibility.%道德风险问题作为贫困生资助工作的重要特征,不仅影响着资助工作的成败,也冲撞着整个社会价值观念和伦理秩序。责任伦理的新型伦理思维范式和至善追求为我们应对资助工作道德风险提供了疗救机制。把责任伦理纳入贫困生资助工作的伦理构建中,是我们应对道德风险挑战的有效途径:一方面加强主体的责任伦理教育,提升责任认识与责任能力;另一方面要建立与资助政策相配套的责任伦理规则和监督评价机制,激发主体履行责任的伦理精神。

    This work proposes a simulation model involving subtraction of digital mammography images obtained at different X-ray beam levels of energy to aid the detection of breast malignant lesions. Absorption coefficients behavior of 3 main structures of clinical interest - adipose tissue, fiber glandular tissue and the typical carcinoma - as a function of the beam energy from a Mo X-ray tube was the basis to develop a computer simulation of the possible acquired images. The simulation has considered a typical compressed breast with 4.5cm in thickness, and variations of the carcinoma and glandular tissues thicknesses - 0.4 up to 2.0cm and 4.1 to 2.5cm, respectively - were evaluated as a function of the photons mean energy - 14 up to 25 keV, in the typical mammography energy range. Results have shown that: (a) if the carcinoma thickness is over 0.4cm, its detection may be feasible even masked by fiber tissue with exposures in the range of 19 to 25 keV; (b) for masked carcinoma with thickness in the range of 0.4-2.0cm, the proposed procedure can enhance it in the image resulting from the digital subtraction between images obtained at 14 and at 22 keV. Therefore such results indicate that this simulation procedure can be a useful tool in aiding the identification of possible missed malignant lesions which could not be detected in the typical exam, mainly considering dense breasts.

    Full Text Available Introduction. LeFort colpocleisis (LFC is a safe and effective obliterative surgical option for older women with advanced pelvic organ prolapse who no longer desire coital activity. A major disadvantage is the limited ability to evaluate for post-LFC gynecologic malignancies. Methods. We present the first case of endometrioid ovarian cancer diagnosed after LFC and review all reported gynecologic malignancies post-LFC in the English medical literature. Results. This is the second reported ovarian cancer post-LFC and the first of the endometrioid subtype. A total of nine other gynecologic malignancies post-LFC have been reported in the English medical literature. Conclusions. Gynecologic malignancies post-LFC are rare. We propose a simple 3-step strategy in evaluating post-LFC malignancies.

    Objective: To detect differential protein expression in malignant and normal liver cell lines in vitro using the SELDI ProteinChip platform, for investigating the pathogenesis of liver cancer. Methods: Two cell lines, human normal liver cell line L02 and hepatoma cell line SMMC-7721 were cultured routinely, harvested in good condition and lysed. After quantification, the supernatant of the lysate was tested by IMAC3 (Immobilized Mental Affinity Capture) and WCX2 (Weak Cation Exchange) chips on the SELDI-TOF-MS ProteinChip reader. Results: Protein expression differed between the malignant and normal liver cell lines. A total of 20 differentially expressed proteins were found, among which, 7 were captured by the IMAC3 chip and 14 by the WCX2 chip. Peaks at 5,419, 7,979 and 11,265 Da were higher and at 8,103, 8,492, 10,160 and 11,304 Da lower in SMMC-7721 cells by the IMAC3 chip; peaks at 7,517, 7,945 and 7,979 Da were higher and at 5,061, 5,551, 5,818, 7,439, 9,401,10,100, 10,312, 11,621, 11,662, 11,830 and 12,772 Da lower in SMMC-7721 cells by the WCX2 chip. Interestingly, both chips captured the 7,979 Da peak. In addition, the 11,081 Da peak corresponded precisely with the molecular mass of the calcium binding protein S100A10, which may participate in the formation of liver cancer in association with p36. Conclusion: Detecting differential protein expression in malignant and normal liver cell lines using the SELDI ProteinChip platform was simple, sensitive and repeatable. The results we obtained can serve as a basis for investigating the pathogenesis of liver cancer and aid the discovery of new therapeutic targets.

  20. Women and AIDS: introduction.

    Around the world, more and more women--principally poor women of color--are being diagnosed with and are dying of AIDS, the acquired immune deficiency syndrome. Yet, effective and appropriate prevention programs for women are sorely missing from the global program to control AIDS. To help us understand why this gap exists, and what we must do to close it, the three articles in this issue focus on women and AIDS. Examining the situation in such countries as Zimbabwe and South Africa, as well as in other economically underdeveloped and developed regions, the authors argue that women with the least control over their bodies and their lives are at greatest risk of acquiring AIDS. For example, the high rate of infection among women in Africa cannot be understood apart from the legacy of colonialism (including land expropriation and the forced introduction of a migrant labor system) and the insidious combination of traditional and European patriarchal values. Only by recognizing the socioeconomic and cultural determinants of both disease and sexual behavior, and only by incorporating these insights into our AIDS prevention programs, will we be able to curb the spread of this lethal disease.

  1. AIDS in Africa.

    Science.gov (United States)

    Mokhobo, D

    1989-03-01

    Numerous cultural practices and attitudes in Africa represent formidable obstacles to the prevention of the further spread of acquired immunodeficiency syndrome (AIDS). Polygamy and concubinage are still widely practiced throughout Africa. In fact, sexual promiscuity on the part of males is traditionally viewed as positive--a reflection of male supremacy and male sexual prowess. The disintegration of the rural African family, brought about by urbanization, the migrant labor system, and poverty, has resulted in widespread premarital promiscuity. Contraceptive practices are perceived by many as a white conspiracy aimed at limiting the growth of the black population and thereby diminishing its political power. Condom use is particularly in disfavor. Thus, AIDS prevention campaigns urging Africans to restrict the number of sexual partners and to use condoms are unlikely to be successful. Another problem is that most Africans cannot believe that AIDS is sexually linked in that the disease does not affect the sex organs as is the case with other sexually transmitted diseases. The degree to which African governments are able to allocate resources to AIDS education will determine whether the epidemic can be controlled. Even with a massive outpouring of resources, it may be difficult to arouse public alarm about AIDS since Africans are so acclimated to living with calamities of every kind.

    Convisser, J

    1992-01-01

    Health communicators use entertainment and mass media to prevent HIV transmission. Population Services International operates an AIDS Mass Media Project as an adjunct to its Condom Social Marketing Project. It collaborates with the Government of Zaire's National AIDS Program. Its 1st target is urban youth because most AIDS cases in Zaire were infected as teenagers, urban youth have access to television (TV), and they take part in high risk sexual behavior. The project uses various AIDS songs to reach this group. A 6-month posttest shows that the 1st song was so effective that 65% heard it and that 93% of them recalled the major AIDS messages and 85% said that they changed their behavior. The project distributes a video of the 1990 World AIDS Day concert. Research in Zaire and other African countries shows that the threat AIDS poses to children's health strongly motivates parents' behavior. Thus the 2nd target is the 20-30 year old group--young and prospective parents. The project boasts a 4-part TV series about a groom who does not reveal his AIDS status to his young bride until after their wedding night. 2 scenes stress the benefits of condoms. After its 1st airing, 66% of the 20-30 year old group in Kinshasa watched all 4 parts of the series. Of these, about 75% said they would change their behavior. Most people in Zaire change behavior by using condoms. Indeed, during the mass media campaign, condom sales grew 1000% which saved almost 7200 lives. The project also features comic strips informing working men and women and teenagers about AIDS and distributes an inexpensive notebook listening AIDS facts and myths for school children. The project uses regional radio stations to broadcast 28 AIDS feature programs, 22 radio spots, 8 AIDS radio dramas, and 2 songs to high priority rural areas. These AIDS radio efforts have indeed influenced AIDS knowledge and attitudes.

    Between January 1984 and December 1987 a total of 178 AIDS cases were reported to the Colombian Ministry of Health. The location of these cases suggests that the human immunodeficiency virus (HIV) is widely distributed in Colombia. Most of those afflicted (97%) have been adult males. HIV seroprevalence studies of selected population groups revealed the highest antibody prevalence (5.65% in females, 22.5% in males) among individuals involved in high-risk behaviors who participated in a free AIDS testing program. High prevalences (from 0.6% to 3.9% in females, and 14.6% to 15.9% in males) were also found in patients (primarily female prostitutes and male homosexuals) attending clinics for sexually transmitted diseases in several urban areas. The number of AIDS cases in Colombia has doubled or tripled annually since reporting began in 1984, a pattern similar to that observed worldwide.

    A study about mortality by AIDS had been undertaken since July 1st 1983, in the Service of Information on Medical causes of Death (INSERM SC8), which is in charge of developing mortality statistics in France. From July 1st 1983 to September 30th 1985, 243 deaths due to AIDS were recorded. Only the cases where this diagnosis was clearly mentioned were selected; more than 90% were notified by hospitals and mainly by highly specialized services. The number of deaths, which was low and varied rather irregularly at the beginning, then increased by successive stages. The first year, during which a tenth of deaths was recorded every three months, was followed by a great increase, doubling, then tripling the initial numbers. Lastly, a second and sudden rise occurred during the third trimester of 1985, the trimestrial number of deaths due to AIDS reaching 80.

    2012-01-01

    Esophageal cancer is mainly found in Asia and east Africa and is one of the deadliest cancers in the world.However,it has not garnered much attention in the Western world due to its low incidence rate.An increasing amount of data indicate that esophageal cancer,particularly esophageal adenocarcinoma,has been rising by 6-fold annually and is now becoming the fastest growing cancer in the United States.This rise has been associated with the increase of the obese population,as abdominal fat puts extra pressure on the stomach and causes gastroesophageal reflux disease (GERD).Long standing GERD can induce esophagitis and metaplasia and,ultimately,leads to adenocarcinoma.Acid suppression has been the main strategy to treat GERD; however,it has not been proven to control esophageal malignancy effectively.In fact,its side effects have triggered multiple warnings from regulatory agencies.The high mortality and fast growth of esophageal cancer demand more vigorous efforts to look into its deeper mechanisms and come up with better therapeutic options.

    2006-01-01

    Malignant mesothelioma (mesothelioma) is rare. We conducted the first systematic study of the epidemiology of mesothelioma in Hong Kong from 1988 to May 2002 by reviewing medical records. Mesothelioma patients were identified from the database of 12 out of 20 hospitals that would have admitted mesothelioma patients territory-wide. These 12 hospitals served 73% of the total hospital bed-years of the 20 hospitals. We identified 67 mesothelioma patients. The estimated annual incidence was one per million, which was similar to the background incidence of one to two per million among Caucasians. Occupational history was available in 43 subjects. Three quarters of mesothelioma patients with available occupational history had occupational asbestos exposure. Restricting analysis to 48 patients with accessible medical records and using 67 occupational asbestosis patients for comparison, the epidemiology of mesothelioma in Hong Kong shares similarities with the literature: mean age of 63 years upon diagnosis, mean latency of 46 years, median survival of 9.5 months, male predominance, selective presentation among women, high prevalence among workers in ships and dockyards, predominantly epithelioid type, lower prevalence of asbestos bodies, and negative association with pleural plaques. Asbestos consumption in Hong Kong rose in the 1970s and peaked in early 1980s and late 1990s. Hong Kong may encounter an epidemic of mesothelioma in the 2010s if effective occupational asbestos control measures are not in place.

    This research project proposes to develop novel new approaches of improving the radioimmunodetection and radioimmunotherapy of malignancies by augmenting retention of radioimmunoconjugates by tumor cells. The approaches shown to be effective in these laboratory experiments will subsequently be incorporated into out ongoing clinical trials in patients. Specific project objectives include: to study the rates of endocytosis, intracellular routing, and metabolic degradation of radiolabeled monoclonal antibodies targeting tumor-associated antigens on human leukemia and lymphoma cells; To examine the effects of lysosomotropic amines (e.g. chloroquine, amantadine), carboxylic ionophores (monensin, nigericin), and thioamides (propylthiouracil), on the retention of radiolabeled MoAbs by tumor cells; to examine the impact of newer radioiodination techniques (tyramine cellobiose, paraiodobenzoyl) on the metabolic degradation of radioiodinated antibodies; to compare the endocytosis, intracellular routing, and degradation of radioimmunoconjugates prepared with different radionuclides ({sup 131}Iodine, {sup 111}Indium, {sup 90}Yttrium, {sup 99m}Technetium, {sup 186}Rhenium); and to examine the utility of radioimmunoconjugates targeting oncogene products for the radioimmunotherapy and radioimmunoscintigraphy of cancer.

  13. Management of intestinal obstruction in advanced malignancy

    Directory of Open Access Journals (Sweden)

    Henry John Murray Ferguson

    2015-09-01

    Full Text Available Patients with incurable, advanced abdominal or pelvic malignancy often present to acute surgical departments with symptoms and signs of intestinal obstruction. It is rare for bowel strangulation to occur in these presentations, and spontaneous resolution often occurs, so the luxury of time should be afforded while decisions are made regarding surgery. Cross-sectional imaging is valuable in determining the underlying mechanism and pathology. The majority of these patients will not be suitable for an operation, and will be best managed in conjunction with a palliative medicine team. Surgeons require a good working knowledge of the mechanisms of action of anti-emetics, anti-secretories and analgesics to tailor early management to individual patients, while decisions regarding potential surgery are made. Deciding if and when to perform operative intervention in this group is complex, and fraught with both technical and emotional challenges. Surgery in this group is highly morbid, with no current evidence available concerning quality of life following surgery. The limited evidence concerning operative strategy suggests that resection and primary anastomosis results in improved survival, over bypass or stoma formation. Realistic prognostication and involvement of the patient, care-givers and the multidisciplinary team in treatment decisions is mandatory if optimum outcomes are to be achieved.

    To investigate the value of dual-energy spectral computed tomography (DESCT) for differentiating malignant vertebral tumours from non-malignancies during venous phase. This study was institutional review board-approved, and written informed consent was obtained from all patients. Thirty-seven patients were examined by DESCT during venous phase. Twenty patients had malignant vertebral tumours, 17 had non-malignant vertebral tumours. The iodine/water densities for the lesion, the lesion-to-muscle ratio, and lesion-to-artery ratio for iodine density measurements were calculated and compared between the two groups with the two-tailed Student t test. A p-value < 0.05 was considered statistically significant. Sensitivity and specificity were compared between the qualitative and quantitative studies. The iodine density, lesion-to-muscle ratio, and lesion-to-artery ratio of the iodine density measurement for malignant vertebral tumours were significantly different from the respective values for non-malignancies (all p < 0.05). Using 0.52 as the threshold value for the lesion-to-artery iodine density ratio, one could obtain sensitivity of 85 % and specificity of 100 % for differentiating malignant vertebral tumours from non-malignancies, significantly higher than the qualitative diagnosis. DESCT imaging enables analysis of a number of additional quantitative CT parameters to improve the accuracy for differentiating malignant vertebral tumours from non-malignancies during venous phase.

    Neuroleptic malignant syndrome is an uncommon but potentially fatal side effect of antipsychotic drug treatment. Several serious complications have been associated with neuroleptic malignant syndrome, such as acute renal failure, deep venous thrombosis, pulmonary embolism and aspiration pneumonia. Reports on infections other than aspiration pneumonia appear, from the literature, to be uncommon. Four cases of infection (three cases of upper respiratory tract infection and one case of urinary tract infection) which developed during the course of neuroleptic malignant syndrome are reported and pathophysiological mechanisms underlying their presentation are suggested.

    Numerous dermatological disorders have been associated with underlining malignancies of the gastrointestinal (GI) tract. Such cutaneous manifestations might have an important diagnostic value if they are the sole expressions of otherwise asymptomatic carcinomas. The recognition of some typical paraneoplastic dermatologic disorders can lead to the prompt diagnosis of the underlying malignancy, timely administration of therapy, and ultimately, better prognosis. In this review we discuss the most common paraneoplastic dermatological syndromes from the perspective of the practicing gastroenterologist. We also outline a comprehensive practical approach for the evaluation for occult malignancy in patients presenting with cutaneous findings potentially associated with GI cancers.

    During the past century, organ transplantation has delivered the miracle of life to more than 500,000 patients in need. Secondary malignancies have developed as an unforeseen consequence of intense immunosuppressive regimens. Cutaneous malignancies have been recognized as the most frequent cancer that arises post-transplantation. Among organ transplant recipients (OTRs), skin cancer is a substantial cause of morbidity and potential mortality. The authors discuss epidemiology and clinical presentation of cutaneous malignancies; associated risk factors; recommendation for the care of immunosuppressed OTRs, and emerging therapies on the horizon.

    2016-01-01

    Circulating free nucleic acids; cell free DNA and circulating micro-RNA, are found in the plasma of patients with hematologic and solid malignancies at levels higher than that of healthy individuals. In patients with hematologic malignancy cell free DNA reflects the underlying tumor mutational profile, whilst micro-RNAs reflect genetic interference mechanisms within a tumor and potentially the surrounding microenvironment and immune effector cells. These circulating nucleic acids offer a potentially simple, non-invasive, repeatable analysis that can aid in diagnosis, prognosis and therapeutic decisions in cancer treatment.

    Full Text Available Abstract Background Its a dilemma to attempt a palliative procedure to debulk the tumour and/or prevent future obstructive complications in a locally advanced intra abdominal malignancy. Case presentation A 38 year old Vietnamese man presented with a carcinoma of the colon which had invaded the gallbladder and duodenum with a sealed perforation of the second part of the duodenum. Following surgical exploration, it was evident that primary closure of the perforated duodenum was not possible due to the presence of unresectable residual tumour. Conclusion We describe a novel technique using a covered duodenal stent deployed at open surgery to aid closure of a malignant duodenal perforation.

  14. Screening for AIDS.

    Science.gov (United States)

    1985-03-29

    Tests to detect serum antibody to human T-lymphotropic virus type III (HTLV-III), based on an enzyme-linked immunosorbent assay (ELISA) that uses whole disrupted HTLV-III virus antigens, are now commercially available in the US. Recent surveys of groups at high risk for acquired immunodeficiency syndrome (AIDS) have found that 22-65% of homosexual men, 87% of active intravenous drug users, 56-72% of hemophiliacs, and 35% of women who were sexual partners of men with AIDS have had postitive ELISA tests compared with fewer than 1% of those with no known risk factors. A positive ELISA test could be due to subclinical infection, immunity, or cross-reactivity with other viral antigens. Laboratory error can also produce false positive results. Thus, it is recommended that the ELISA test be repeated at least once on all seropositive specimens before the result is reported to the patient. The western blot test appears to be more specific and less sensitive than the ELISA. Studies of asymptomatic seropositive homosexual men followed for 2-5 years have found that over 50% remain asymptomatic, 5-19% develop full blown AIDS, and 25% develop signs suggestive of the AIDS-related complex. Asymptomatic patients with positive ELISA tests should be made aware of early signs and symptoms of AIDS. Other data suggest that seropositive patients have the HTLV-III virus in their blood, semen, and/or saliva and can transmit the infection. Precautions to prevent transmission, such as the use of condoms, should be taken by such patients. Physicians should be sensitive to the fear and anxiety that a positive ELISA test will create.

    2005-08-01

    Full Text Available Introduction & Background: Breast cancer is a lead-ing cause of cancer deaths among women.Early de-tection is the most effective way to reduce mortality. Mammography is the best method for early detection. In order to improve the accuracy of interpretation of mammogram, Computer Aided Diagnosis (CAD sys-tems have been proposed. The main goal of this re-search is to implement one of the algorithms and techniques for the enhancement of mammogram for easier detection of abnormalities. Patients & Methods: In the presented algorithm, morphological methods are used first for removing artifacts. Then thresholding, labeling, and active con-tours methods are used to extract the breast region, which allow the search for abnormalities to be lim-ited to the region of the breast. Finally, Gaussian fil-ter and White Top Hat Transform is used for contrast enhancement of mammogram. This algorithm has been applied on 50 images from Mammography Im-age Analysis Society (MIAS. An expert radiologist then verified improvement on the processed images. Results and Conclusions: Implementing the presented algorithm causes easier and better interpretation of mammogram without increasing the number of false positive and false negative results. Because of the spe-cial shapes and statistical features of abnormal tex-tures, it is possible to apply pattern recognition and artificial intelligence techniques as an aid for diagnos-ing suspicious regions. Research on using some of these techniques to distinguish benign abnormalities from malignant ones is on the way.

    2015-03-26

    Il Melanoma Anorettale è una malattia rara e aggressiva ed è il terzo tipo più comune di melanoma maligno dopo quello della cute e della retina. Il sintomo più comune è il sanguinamento rettale, che è spesso scambiato per sanguinamento associato a emorroidi. La diagnosi è molto difficile, e quella iniziale può essere corretta solo in circa 80% dei casi. Il caso clinico che proponiamo riguarda un uomo di 71 anni giunto alla nostra osservazione per dolore anale, tenesmo rettale, sanguinamento. L’eplorazione rettale ci ha mostrato una neofromazione dolorosa, di colorito brunastro nel canale anale. La colonscopia e la endoscopia hanno evidenziato la presenza di una grande massa stenotica interessante il canale anale ed il retto con un diametro di circa 90 mm. La biopsia è positiva per melanoma a cellule maligne pigmentate. La TAC ha mostrato un ispessimento della parete rettale e linfonodi nel tessuto adiposo, nel distretto otturatore bilaterale e metastasi polmonari bilaterali. Il dato di laboratorio del Ca 19-9 è nei livelli normali. Il paziente è stato sottoposto a resezione addomino-perineale con dissezione linfonodale. Non ci sono studi dimostranti che la resezione radicale del melanoma primario ano-rettale è associata ad un miglioramento del controllo locale e della sopravvivenza. I pazienti con malattia localizzata dovrebbero essere sottoposti a escissione locale ogniqualvolta ciò sia tecnicamente fattibile. Il ruolo predominante del trattamento chemio radioterapico preoperatorio è quello di ridurre le recidive locoregionale e della cavità pelvica, e per ottenere un più alto tasso di conservazione dell’apparato sfinteriale. Inoltre facilita la rimozione delle potenziali micrometastasi e riduce le metastasi a distanza.

    Malignant biliary obstruction is commonly caused by gall bladder carcinoma, cholangiocarcinoma and metastatic nodes. Percutaneous interventions play an important role in managing these patients. Biliary drainage, which forms the major bulk of radiological interventions, can be pal iative in inoperable patients or pre-operative to improve liver function prior to surgery. Other interventions include cholecystostomy and radiofrequency ablation. We present here the indications, contraindications, technique and complications of the radiological interventions performed in patients with malignant biliary obstruction.

    Since it is still an open debate whether malignant tumors are mainly influenced by environmental factors, the frequency of such malignant tumors in historic populations with different living conditions is of particular interest. In the present study, we investigated the occurrence of malignant tumors affecting bone tissue in a population of mumrnies and skeletons, which had been excavated from the large necropolis of Thebes-West, Upper Egypt. Our study material comprised a series of at least 415 individuals (thereof 325 adults) dating from approx. 1500-500 B.C. All individuals had been mummified, but were severely damaged and partially broken by grave robbers, so that often only parts of the mummies/skeletons were available for investigation. The available specimens were subjected to careful macroscopic examination, while isolated findings were radiologically analyzed. Using this approach, we identified at least 4 cases showing malignant tumors affecting the skeleton. In two cases, multiple mixed osteolytic-osteoblastic lesions suggested multiple metastases from carcinomas. Two further individuals presented with multiple osteolyses (vertebra, pelvis, skull) most suggestive of multiple myeloma. The observation of at least 4 cases of malignant tumors with osseous manifestation in a series of 325 adult individuals provides clear evidence that malignant tumors were not a rare event in the ancient Egyptian study population, particularly when the limitations of a study of tumors manifested only in osseous remnants are taken into consideration. A calculation of the age- and sex-adjusted tumor frequency in our material in comparison with a recent model for such a material by Waldron (1996) indicates that the rate of malignant tumors with bone affection in our series is higher than in an English population from 1901-1905, although lower than in a comparable present day population. This clearly indicates that important factors affecting malignant tumors were effective even

    2011-05-01

    Full Text Available In this work, we are motivated by the desire to classify skin lesions as malignants or benigns from color photographic slides of the lesions. Thus, we use color images of skin lesions, image processing techniques and artificial neural network classifier to distinguish melanoma from benign pigmented lesions. As the first step of the data set analysis, a preprocessing sequence is implemented to remove noise and undesired structures from the color image. Second, an automated segmentation approach localizes suspicious lesion regions by region growing after a preliminary step based on fuzzy sets. Then, we rely on quantitative image analysis to measure a series of candidate attributes hoped to contain enough information to differentiate melanomas from benign lesions. At last, the selected features are supplied to an artificial neural network for classification of tumor lesion as malignant or benign. For a preliminary balanced training/testing set, our approach is able to obtain 79.1% of correct classification of malignant and benign lesions on real skin lesion images.

The sample consisted of 120 examinees (60 examinees from the E group and 60 examinees from the K group. The criteria for the formation of the E group were: age 8-18 years old; diagnosis of the malignant diseases confirmed with a histopathological verification (consistent tumors and malignant hemopathy; treatment on the children department for OR (hemiotherapy, radiotherapy, combined hemopathy; fine pre morbid status. The control group consisted of healthy examinees that according to the number, age, sex and the level of education were adequate to the examinees from the E group.With comparison of the average accomplishments of the examinees from groups E and K in the field of social competence we obtained a statistically significant difference between the examined groups in benefit to the examinees from group K. The social incompetence and social exclusion that follow the malignant disease represented a basic indication for special education and rehabilitation of children and young people that suffer from malignant diseases.

    Full Text Available Malignant ameloblastoma, comprising metastasizing ameloblastoma and ameloblastic carcinoma, represents 1.6-2.2% of all odontogenic tumors. Due to its rare nature, malignant ameloblastoma has only been reported in the literature in small case series or case reports. Using the Surveillance, Epidemiology and End-Results (SEER database, we have performed a population-based study to determine the incidence rate and the absolute survival of malignant ameloblastoma.Using the International Classification of Diseases for Oncology (ICD-O codes 9310/3 and 9270/3, data from the SEER database were used to calculate the incidence rate and absolute survival rate of population with malignant ameloblastoma.The overall incidence rate of malignant ameloblastoma was 1.79 per 10 million person/year. The incidence rate was higher in males than females and also higher in black versus white population. The median overall survival was 17.6 years from the time of diagnosis and increasing age was associated with a statistically significant poorer survival.To our best knowledge, we report the largest population-based series of malignant ameloblastoma. The incidence rate was 1.79 per 10 million person/year and the overall survival was 17.6 years.

  13. Endoscopic treatment of malignant biliary strictures.

    Rustagi, Tarun; Jamidar, Priya A

    2015-01-01

    Endoscopic stenting is a widely accepted strategy for providing effective drainage in both extrahepatic and intrahepatic malignant strictures. In patients with extrahepatic malignancies, uncovered self-expanding metal stents (SEMS) provide excellent palliation. Hilar malignancies are probably best palliated by placement of uncovered SEMS although some disagreement exists among experts regarding the type and number of stents for optimal palliation. Preoperative biliary drainage (PBD) is commonly performed although a higher risk of complications and the lack of clear benefit raise questions about this practice. Certain groups of patients such as those with markedly elevated bilirubin levels, and in those in whom neoadjuvant therapy is planned, are good candidates for PBD. Considerable controversy exists regarding the optimal method as well as type of stent for PBD in patients with hilar malignancies. Novel endoscopic therapies, including photodynamic therapy and radiofrequency ablation, have emerged as potential adjuvant therapies in the management of malignant bile duct strictures but need further long-term evaluation to establish survival benefit. This review focuses on the current status of endoscopic therapies for malignant biliary obstructions.

    Does perceived corruption in recipient countries reduce support for foreign aid in donor countries? This under-explored yet salient question is examined using the 2009 Eurobarometer survey for the 27 EU countries. We suggest that perceived corruption can cause aid fatigue but that this relationship...... is highly contextualized. The results show that perceptions about corruption in developing countries reduce overall support for aid among respondents in donor countries. However, this effect is mitigated by country and contextual-level effects and different understandings of what we call the “aid-corruption...... paradox,” namely that the need for foreign aid is often the greatest in corrupt environments. Three different dynamics of the aid-corruption paradox influence support for aid: moral, pragmatic, and strategic understandings. In EU-15 countries, the effect of perceived corruption in recipient states on aid...

    2015-01-01

    After highly active antiretroviral therapy (HAART) became widespread, several studies demonstrated changes in the incidence of defining and non-defining AIDS cancers among HIV/AIDS patients. We conducted a systematic review of observational studies evaluating the incidence of malignancies before and after the introduction of HAART in people with HIV/AIDS. Eligible studies were searched up to December 2012 in the following databases: Pubmed, Embase, Scielo, Cancerlit and Google Scholar. In this study, we determined the cancer risk ratio by comparing the pre- and post-HAART eras. Twenty-one relevant articles were found, involving more than 600,000 people with HIV/AIDS and 10,891 new cases of cancers. The risk for the development of an AIDS-defining cancer decreased after the introduction of HAART: Kaposi's sarcoma (RR=0.30, 95% CI: 0.28-0.33) and non-Hodgkin's lymphoma (RR=0.52, 95% CI: 0.48-0.56), in contrast to invasive cervical cancer (RR=1.46, 95% CI: 1.09-1.94). Among the non-AIDS-defining cancers, the overall risk increased after the introduction of HAART (RR=2.00, 95% CI: 1.79-2.23). The incidence of AIDS-defining cancers decreased and the incidence of non-AIDS-defining cancers increased after the early use of HAART, probably due to better control of viral replication, increased immunity and increased survival provided by new drugs.

    Full Text Available Idiopathic inflammatory myopathies (IIM are a heterogeneous group of acquired systemic diseases mainly involving skeletal muscles. The main representatives of IIM are polymyositis (PM and dermatomyositis (DM. Epidemiological surveys demonstrate that there is a relationship between PM/DM and malignant neoplasms (MNs, the detection risk of which is higher than that in the population of respective age groups. The rate of MNs in PM/DM ranges from 9 to 50%. The relationship to MNs is described in each subtype of IIM; however, these are most common in DM. The patients suffering from PM/DM associated with MNs have a worse prognosis than those without MNs. The early detection of MNs could improve the prognosis in these patients. The investigations published identify demographic, clinical, and laboratory factors increasing MN detection risks in patients with PM/DM. Just the same, they all cover small patient groups; the findings are heterogeneous and not well convincing, which calls for a further larger-scale study of this problem.Objective: to reveal and identify the specific features of paraneoplastic myositis (PnM.Subjects and methods. The investigation included 320 patients with a valid diagnosis of IIM, who had been followed up in the period of 1996 to 2016. The patients underwent laboratory tests, manual proximal muscle strength testing using a 10-point scale and electromyographic examination with needle electrodes.Results and discussion. PnM was detected in 32 (10% of the 320 patients with IIM. Among the patients with PnM, there were 6 (19% men and 26 (81% women. The mean age at the onset of PnM was 55.4 years. PnM manifested with characteristic musculocutaneous syndrome in 19 (59% patients; 18 (41% of them were found to have MNs within the first year after disease onset. The manifestation of MNs was preliminary to the picture of PM/DM in 13 (41% patients. The most commonly detected conditions were ovarian cancer (37.5%, MNs of the lung and breast

  20. Febrile neutropenia in haematological malignancies

    2005-01-01

    Full Text Available Fever is the principle sign of infection in neutropenic patient and frequently may be the only evidence of infection. The pattern of fever in neutropenia is non-specific and not pathognomonic of any type of infections or non-infectious process and can be suppressed by the antipyretic effects of drugs such as corticosteroids. Neutropenia, resulting from cytotoxic chemotherapy is the most common risk factor for severe infections in hematological malignancies. The duration of neutropenia also contributes significantly to the risk of serious infections. This risk is significantly greater a lower neutrophil counts, such that 100% patients with ANC < 100 cells/µl lasting 3 weeks or more develop documented infections. The prompt initiation of empirical antibiotics in febrile neutropenia has been the most important advance in the management of the immunocompromised host. The initial empirical antibiotic regimen started at presentation of the febrile episode frequently requires modifications especially in high-risk febrile neutropenia. Neutropenic patients who remain febrile despite 4-7 days of broad spectrum antibacterial therapy are at a high risk of invasive fungal infection. Empirical antifungal therapy with Amphotericin B in persistently febrile neutropenic patients and other high risk patients has shown to reduce the risk of invasive fungal infection by 50-80% and the risk of fungal infection related mortality by 23-45% in 1980′s. The IDSA has recommended that amphotericin B at 0.5-0.7 mg/kg/day be administered till marrow recovery. This approach is limited however by the adverse effects caused by drug infusion (fever, chills, myalgias, nausea, hypotension and bronchospasm. Lipid formulations which improve the therapeutic ratio of the traditional formulation are available. The safety and efficacy of these formulations is well established. These formulations have comparable efficacy and are less nephrotoxic than conventional amphotericin B

    Malignant melanoma of the skin is the most aggressive human cancer given that a primary tumor a few millimeters in diameter frequently has full metastatic competence. In view of that, revealing the genetic background of this potential may also help to better understand tumor dissemination in general. Genomic analyses have established the molecular classification of melanoma based on the most frequent driver oncogenic mutations (BRAF, NRAS, KIT) and have also revealed a long list of rare events, including mutations and amplifications as well as genetic microheterogeneity. At the moment, it is unclear whether any of these rare events have role in the metastasis initiation process since the major drivers do not have such a role. During lymphatic and hematogenous dissemination, the clonal selection process is evidently reflected by differences in oncogenic drivers in the metastases versus the primary tumor. Clonal selection is also evident during lymphatic progression, though the genetic background of this immunoselection is less clear. Genomic analyses of metastases identified further genetic alterations, some of which may correspond to metastasis maintenance genes. The natural genetic progression of melanoma can be modified by targeted (BRAF or MEK inhibitor) or immunotherapies. Some of the rare events in primary tumors may result in primary resistance, while further new genetic lesions develop during the acquired resistance to both targeted and immunotherapies. Only a few genetic lesions of the primary tumor are constant during natural or therapy-modulated progression. EGFR4 and NMDAR2 mutations, MITF and MET amplifications and PTEN loss can be considered as metastasis drivers. Furthermore, BRAF and MITF amplifications as well as PTEN loss are also responsible for resistance to targeted therapies, whereas NRAS mutation is the only founder genetic lesion showing any association with sensitivity to immunotherapies. Unfortunately, there are hardly any data on the

    Helicobacter pylori infection is the principal trigger of gastric carcinogenesis and gastric cancer (GC) and remains the third leading cause of cancer-related death in both sexes worldwide. In a big Japanese study, the risk of developing GC in patients with peptic ulcer disease who received H. pylori eradication therapy and annual endoscopic surveillance for a mean of 9.9 years was significantly lower after successful eradication therapy compared to the group with persistent infection (0.21%/year and 0.45%/year, respectively, p = .049). According to a recent meta-analysis, H. pylori eradication is insufficient in GC risk reduction in subjects with advanced precancerous conditions (i.e., intestinal metaplasia and dysplasia). A microsimulation model suggested screening smokers over the age of 50 in the U.S. for serum pepsinogens. This would allow to detect advanced gastric atrophy with endoscopic follow-up of subjects testing positive as a cost-effective strategy to reduce GC mortality. In a Taiwanese study, the anti-H. pylori IgG-based test-and-treat program had lower incremental cost-effectiveness ratios than that with (13)C-urea breath test in both sexes to prevent GC whereas expected years of life lost for GC were higher and the incremental cost-effectiveness ratios of test-and-treat programs were more cost-effective in young adults (30-69 years old) than in elders (>70 years old). With respect to gastrointestinal malignancies other than GC, a meta-analysis confirmed the inverse association between H. pylori infection and esophageal adenocarcinoma. In a Finnish study, H. pylori seropositivity was associated with an increased risk of biliary tract cancers (multivariate adjusted OR 2.63; 95% CI: 1.08-6.37), another meta-analysis showed a slightly increased rate of pancreatic cancer in patients with CagA-negative strains (OR: 1.30; 95% CI: 1.02-1.65), whereas current data suggest that the association between H. pylori and colorectal neoplasms may be population

    1986-02-01

    Since 1982 (Hauser and co-workers), literature has reported focal cerebral tissue charges in AIDS patients whose diagnosis was unclear at first but which could be identified finally as florid toxoplasmosis encephalitis by biopsy and autopsy. It was found that the value of otherwise reliable serological tests (KBR, Sabin-Feldmann tests, etc.) is questionable in patients with severely impaired or incompetent immune systems, and, in particular, that a negative or uncharacteristic test result may not preclude any opportunistic infection process. Furthermore, isolation of Toxoplasma gondii or specific antibodies from the cerebrospinal fluid will be successful in exceptional cases only. In patients with AIDS or lymphadenopathy syndrome, the differential diagnosis will have to include - first and foremost - reactivated toxoplasma infection (not newly acquired, as a rule) if central neurological symptoms occur.

    Full Text Available Tuberculosis (TB remains uniquely important among acquired immune deficiency syndrome (AIDS-associated opportunistic infections: it presents the greatest public health hazard worldwide, is the most readily curable, and is largely preventable with existing means. Given the expanding pool of human immunodeficiency virus (HIV seropositive persons, particularly in developing nations where Mycobacterium tuberculosis remains a leading health problem, one can expect a continued rise in TB cases during the 1990s. Global efforts to eliminate TB are now inextricably entwined with the effectiveness of measures to curtail the HIV epidemic. Mycobacterium avium complex infection, currently an intractable late complication of aids, may increase in clinical importance as success in managing other opportunistic infections and HIV disease itself improves. Understanding of the pathogenesis and management of mycobacterial diseases should increase rapidly given the renewed research spurred on by the advent of HIV.

    We retrospectively reviewed our series of 35 pulmonary mycosis in patients with AIDS, observed from 1987 to 1999, to correlate the imaging and pathologic findings. We further evaluated the frequency of fungal pneumonia before and after the use of a highly active antiretroviral therapy (HAART). Early recognition of pulmonary mycosis is imperative in these patients and improved survival can be achieved with early CT detection and prompt institution of high-dose antifungal therapy.

  14. Has aid for AIDS raised all health funding boats?

    Science.gov (United States)

    Shiffman, Jeremy; Berlan, David; Hafner, Tamara

    2009-11-01

    Global health analysts have debated whether donor prioritization of HIV/AIDS control has lifted all boats, raising attention and funding levels for health issues aside from HIV/AIDS. We investigate this question, considering donor funding for 4 historically prominent health agendas-HIV/AIDS, health systems strengthening, population and reproductive health, and infectious disease control-over the decade 1998-2007. We employ funding data from the Development Assistance Committee of the Organization for Economic Cooperation and Development, which tracks donor aid. The data indicate that HIV/AIDS may have helped to increase funding for the control of other infectious diseases; however, there is no firm evidence that other health issues beyond the control of infectious diseases have benefited. Between 1998 and 2007, funding for HIV/AIDS control rose from just 5.5% to nearly half of all aid for health. Over the same period, funding for health systems strengthening declined from 62.3% to 23.9% of total health aid and that for population and reproductive health declined from 26.4% to 12.3%. Also, even as total aid for health tripled during this decade, aid for health systems strengthening largely stagnated. Overall, the data indicate little support for the contention that donor funding for HIV/AIDS has lifted all boats.

  15. AIDS Research and Its Role in China's AIDS Prevention and Control Policies

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    By the end of 2005, the estimated number of HIV infected people in China was 650,000. The seriousness of the epidemic calls for effective control measures to tackle the problems in order to avoid the tragedy in Africa from happening in China. "Prevention First" is the cornerstone of the country's health policy. On 2003 World AIDS Day, Premier Jiabao Wen announced a new national AIDS control policy, "Four Frees and One Care". This policy clearly shows that the Chinese government has once again taken full responsibility to solve public health problems and has profound impact far beyond the AIDS field. In early 2006, the central government put scientific and technology innovation as a national priority and set the target to build an innovative China by year 2020. Since then, the government has been increasing investment in science and technology with major emphasis on both infectious diseases control and new drug research and development. For the first time, development of 100 new drugs and control of major infectious diseases (AIDS, HBV, TB and other emerging infectious diseases) have been selected as national key scientific projects. China's best minds in related fields will be pooled to work together in order to remove the technical barriers blocking efficient control of the major infectious disease in China. Knowledge on molecular epidemiology, immunology, pathogenesis, HAART, as well as HIVDR strains will certainly provide urgently needed scientific information for China's AIDS control program. Only evidence-based strategy from good research will provide long-term effective control of AIDS.

    Sub-Saharan Africa is the epicenter of the HIV/AIDS epidemic, and in this issue of the Journal, seven authors discuss the moral, social and medical implications of having 70% of those stricken living in this area. Anton A. van Niekerk considers complexities of plague in this region (poverty, denial, poor leadership, illiteracy, women's vulnerability, and disenchantment of intimacy) and the importance of finding responses that empower its people. Solomon Benatar reinforces these issues, but also discusses the role of global politics in sub-Saharan Africa, especially discrimination, imperialism and its exploitation by first world countries. Given the public health crisis, Udo Schüklenk and Richard E. Ashcroft defend compulsory licensing of essential HIV/AIDS medications on consequentialist grounds. Keymanthri Moodley discusses the importance of conducting research and the need to understand a moderate form of communitarianism, also referred to as "ubuntu" or "communalism", to help some Africans understand research as an altruistic endeavour. Godfrey B. Tangwa also defends traditional African values of empathy and ubuntu, discussing how they should be enlisted to fight this pandemic. Loretta M. Kopelman criticizes the tendency among those outside Africa to dismiss the HIV/AIDS pandemic, attributing one source to the ubiquitous and misguided punishment theory of disease. The authors conclude that good solutions must be cooperative ventures among countries within and outside of sub-Saharan Africa with far more support from wealthy countries.

    Britain has longed followed a disease-control strategy for providing aid in the health sector to developing, low-income countries. Given, however, the high level of waste upon tertiary care and specialized medicine in current health programs of low-income countries as documented by the World Bank; the poor performance of existing general government hospitals and clinics; and the poor image of Third World health systems in the eyes of Western officials and government ministers, the chief health advisor of the Overseas Development Administration has called for a drastic redirection of policy toward development aid. Specifically, a shift away from a specific-disease control approach toward an overall, sweeping reform of the health sector in developing countries is urged. The level of waste needs to be reduced and more attention given to the poor. Unless such changes result, government ministers will grow increasingly reluctant to provide tangible aid to the health sectors of countries in need. The availability of such funds invested in effective, well-managed health programs will grow more critical to health in the Third World as populations shift away from communicable disease morbidity and mortality toward illnesses which are of a more noncommunicable nature such as stroke and cancer.

    Phyllode tumor (PT) is extremely rare tumor of the breast. Distant metastasis occurs in 10-20% of patients with malignant phyllode tumor. The most common sites of metastases are the lungs and bones. Although theoretically any organ may have metastasis, an isolated duodenum metastasis has not been documented as yet in the English-language literature. We report herein a case with a isolated duodenal metastasis from PT of breast in a 31 year-old-woman who underwent right mastectomy 4 years before because of the recurrent malignant PT. She presented to our hospital with massive upper gastrointestinal bleeding. Clinical evaluation revealed a huge mass originated from duodenum. Urgent laparotomy and pancreaticoduodenectomy were carried out in order to remove the bleeding duodenal mass.The pathologic examination of the resected specimen showed a malignant spindle cell tumor consistent with metastatic malignant PT. Our case of gastrointestinal bleeding due to an isolated duodenal metastasis as a result of hematogenous spread from malignant phyllode tumor of breast is unique in the English literature and pancreaticoduodenectomy is a curative treatment for patients with isolated duodenal involvement.

It is characterized by distinctive clinical features including a change in mental status, generalized rigidity, hyperpyrexia, and dysautonomia. It can be lethal if not diagnosed and treated properly. Mortality and morbidity attributed to this syndrome have recently declined markedly due to greater awareness, earlier diagnosis, and intensive care intervention. In most cases, the syndrome occurs as a result of a rapid increase in a dose of neuroleptic, especially one of the long-acting ones. Pathophysiology behind this syndrome is attributed to a dopamine receptor blockade inside the neurons rendered by the offending drug and excessive calcium release from the sarcoplasmic reticulum of skeletal myocytes. Laboratory tests, although not diagnostic, may assist in assessing the severity of the syndrome and also the consequent complications. The syndrome has been described in all age groups and occurs more in males than in females. Genetics appears to be central regarding the etiology of the syndrome. Stopping the use of the offending agent, cold intravenous fluids, and removal of the causative agent and its possible active metabolites is the cornerstone of treatment. Periodic observation of psychotic patients recently started on antipsychotic medications, especially those being treated with depot preparations, may aid to an early diagnosis of the syndrome and lead to early treatment.

    BACKDROUND: Ovarian carcinoma is a leading cause of death in gynecological malignancy. Ovarian surface epithelial serous and mucinous tumours are classified as benign, borderline, and malignant. The identification of borderline tumours most likely to act aggressively remains an important clinical issue. AIM: This work aimed to study DNA ploidy and nuclear area in ovarian serous and mucinous; benign, borderline and malignant tumours. MATERIAL AND METHODS: This study included forty ovarian (23 serous and 17 mucinous) tumours. Paraffin blocks were sectioned; stained with haematoxylin and eosin for histopathologic and morphometric studies and with blue feulgen for DNA analysis. RESULTS: All four serous and six out of nine mucinous benign tumours were diploid. All eight serous and five mucinous malignant tumours were aneuploid. Nine of eleven (81.8%) serous and all three mucinous borderline tumours were aneuploid. There were highly significant differences in mean aneuploid cells percentage between serous benign (1.5%), borderline (45.6%) and malignant (74.5%) (p = 0.0001) and between mucinous benign (13.2%) and both borderline (63.7%) and malignant (68.4%) groups (p = 0.0001). There were significant differences in nuclear area between serous benign (26.191%), borderline (45.619%) and malignant (67.634 %) and a significant positive correlation between mean percentage aneuploid value and mean nuclear area in all serous and mucinous groups. CONCLUSION: We suggest that DNA ploidy and nuclear area combined, may be adjuncts to histopathology; in ovarian serous and mucinous benign, borderline and malignant neoplasms; identifying the aggressive borderline tumours.

    2012-02-01

    This work presents the creation of a semantic lesion database which will support research into computer-aided lesion detection (CAD) in breast screening MRI. As an adjunct to conventional X-ray mammography, MR-mammography has become a popular screening tool for women with a high risk of breast cancer because of its high sensitivity in detecting malignancy. To address the needs of research and development into CAD for breast MRI an integrated tool has been designed to collect all lesion related information, conduct quantitative analysis, and then present crucial data to clinicians and researchers. A lesion database is an essential component of this system as it provides a link between the DICOM database of MR images and the meta-information contained in the Electronic Patient Record. The patient history, radiology reports from MRI screening visits and pathology reports are all collected, dissected, and stored in a hierarchical structure in the database. Moreover, internal links between pathology specimens and the location of the corresponding lesion in the image are established allowing diagnostic information to be displayed alongside the relevant images. If "ground truth" for an imaging visit can be established either by biopsy or by 2-year follow-up, then the case is labeled as suitable for use in training and testing CAD algorithms. At present a total of 1882 lesions (benign/malignant), 200 pathology specimens over 405 subjects and 1794 screening (455 CAD studies) are included in the database. As well as providing an excellent resource for CAD development this also has potential applications in resident radiologists' training and education.

  7. Pakistan launches media blitz on AIDS.

    In March 1994, the National AIDS Prevention and Control Programme in Pakistan launched its media campaign. Staffers have had to work within Islamic principles to inform the public about the risk of HIV infection and to encourage the public to adopt behavior to prevent its transmission. The media messages are not sexually explicit. They call for Pakistanis to call a hotline for or to ask medical professionals about more detailed information on AIDS. The hotline number is memorable (123). The 2 hotlines in Islamabad receive 250-300 calls/day. These hotlines deliver a recorded message with information on the significance of condoms in AIDS prevention and allows callers an opportunity to leave a telephone number or address if they want information. Staff advise callers who are concerned that they may be infected with HIV to obtain a test at 1 of 30 sites and to attend the National Institute for Health in Islamabad for more testing and counseling if the first test is positive. The hotline system will soon expand to all other major Pakistani cities. The program receives 300-400 letters/week asking for specific information. The program had workshops for journalists as its first wave of increasing AIDS awareness. The journalists followed with thoughtful articles on AIDS. Program staff spent much energy to obtain support from Islamic leaders. More media professionals have joined efforts to disseminate information through various media forums to encourage people to seek treatment for sexually transmitted diseases. The program's goal is a 55% increase in the number of people who can name at least 2 correct ways to prevent HIV transmission and an increase in condom use from 1% to 70%. The program eventually would like to increase outreach efforts by working with nongovernmental organizations and by developing videos and short stories.

    With the rapid development of network technologies, it is necessary to make use of an aided tool (AT) to help enterprise network design (END). The AT must process many requirements qualitatively and quantitatively, and then give out the logical network guidance and preferred solution. The AT also needs to carry out a simulation program, and gives the feasibility report. This paper will introduce the authors' research work on above aspects.

    2014-09-01

    Full Text Available Thioredoxin system comprised of thiorexin and NADPH dependent thiorexin reductase, is responsible for redox regulation of cells by controlling the apoptosis, proliferation and other vital processes of cells. The efficacy of thioredoxin system has been represented in a wide range of physiological and biological reactions in bacteria, yeast, plants, mammals and etc. including DNA synthesis, regulation of transcription factors, protein repairing, regulating the photosynthesis and controlling the apoptosis and preventing oxidative stresses, filamentous phage assembly, immune-modulating, neuronal survival, pregnancy and birth and many other  physiological and biological functions. The up-regulation of thioredoxin has been observed in various malignancies, which was associated with tumor angiogenesis and development. In this regard, the thiordoxin system has become a putative target in new chemotherapeutic methods. In this study, we mentioned various features of thioredoxin system in malignant cells and reviewed the articles which have evaluated the expression rate of thioredoxin system in malignancies.

    This case report describes a 54-year-old man with bipolar I disorder who was treated with aripiprazole (ARP) and lithium. The patient was admitted to our hospital because of aggravation of depressive symptoms, and treatment with lamotrigine (LTG) was initiated. Two weeks after admission, we discontinued administration of ARP after the appearance of a tremor. Three weeks after discontinuing ARP, the patient developed a high fever, rigidity of the arms, diarrhea, dysphagia, and diaphoresis. We suspected these symptoms were consistent with neuroleptic malignant syndrome and therefore removed the application of LTG. After 2 days, most of the patient's symptoms and blood results had improved, leading us to conclude that the LTG treatment had induced neuroleptic malignant syndrome. Thus, the purpose of this case report was to warn psychiatrists against therapy with LTG, as it may be conducive to neuroleptic malignant syndrome.

    Full Text Available Malignant fibrous histiocytoma of soft part is rather common but malignant fibrous histiocytoma of the bone is rarely encountered clinically. Authors present five cases of malignant fibrous histiocytoma with skeletal involvement and discuss their clinical course, x-ray findings and histological features. This tumor has marked tendency for local recurrence and metastasis. Other bone tumors such as giant cell tumor, aneurysmal bone cyst, non ossifying fibroma, osteosarcoma, fibrosarcoma of bone and metastatic cancer can be excluded by several characteristic findings observed in x-rays as well as histopathological features. All information on the patient should be carefully analysed, because it is difficult to decide whether bone involvement is primary or secondary. Four out of five cases definitely originated within the bone.

    2011-12-01

    Full Text Available Malignant mesothelioma is a highly aggressive neoplasm. The incidence of malignant mesothelioma is increasing worldwide. Diffuse malignant peritoneal mesothelioma (DMPM represents one-fourth of all mesotheliomas. Association of asbestos exposure with DMPM has been observed, especially in males. A great majority of patients present with abdominal pain and distension, caused by accumulation of tumors and ascitic fluid. In the past, DMPM was considered a pre-terminal condition; therefore attracted little attention. Patients invariably died from their disease within a year. Recently, several prospective trials have demonstrated median survival of 40 to 90 months and 5-year survival of 30% to 60% after the combined treatment using cytoreductive surgery and perioperative intraperitoneal chemotherapy. This improvement in survival has prompted new searches into the medical science related to DMPM, a disease previously ignored as uninteresting. This review article focuses on the key advances in the epidemiology, diagnosis, staging, treatments and prognosis of DMPM that have occurred in the past decade.

  14. [Adolescence and AIDS].

    Science.gov (United States)

    1991-01-01

    The myths and prejudices that distort the reality and hide the true causes and effects of natural and social phenomena related to sexuality have a fertile ground in AIDS, given its obvious link to sex. The alarming spread of AIDS has been 1 result of these myths and prejudices. Human beings are sexual by nature; genital organs determine sex and also induce sexual behavior. It is by not fairly well accepted that an individual's sexuality exists from birth. Puberty usually begins at 12-16 years for both sexes. The physical changes of puberty terminate in the ability of the female to conceive and the male to procreate. The sexual excitation of adolescents resulting from production of various hormones can only be eliminated by some type of sexual satisfaction or sublimation. Sexuality, according to Freud, is an organizing principle of the personality. The sexual organs exist not merely for reproduction but to provide pleasure. Puberty signifies entry into active sex life. But the ideological structure of society, perpetuated by the family, schools, religion, the mass media, and other social institutions, sends confused signals to adolescents, requiring abstinence and virginity until marriage for women while encouraging sexual adventures for men. Adolescents are confronted by their new sexual feelings in the midst of a virtual bombardment of visual sexual stimuli from the mass media. It becomes impossible for adolescents to satisfy the requirements of appearances while also resolving the problems and pressures of their newly gained sexual maturity. Many adolescents become sexually active, and the problem is not to prevent sexual activity but to improve the conditions under which it occurs. Adolescents, lacking education and information about sex, begin their sex lives without protection. AIDS has now been added to the list of dire consequences that can result. A true sex education beginning in the home is needed to enable young people to develop healthy and full sex

    Full Text Available The occurrence of a second malignancy in a patient with a known malignant tumour is not uncommon. Synchronous primary malignancies are still unusual We are presenting two cases treated successfully at our centre. Case report 1-A 70 year old female presented to us with lump in right breast for two years and bleeding per vaginum for two years.Histopathology of cervix showed squamous cell carcinoma (large cell non keratinizing and clinical stage was IIIB. HPE mastectomy specimen showed infiltrating duct carcinoma and stage II. Patient was treated with external beam radiotherapy for carcinoma cervix and breast simultaneously and chemotherapy as required. Patient is on regular follow up and clinically no evidence of disease. Case Report 2 -A 40 year old female presented with mild headache off and on for one year, projectile vomiting for three months and right side facial swelling for three months. HPE brain tissue showed astrocytoma grade II and HPE parotid tumour showed low grade muco-epidermoid carcinoma. Patient was treated with surgery first then radiotherapy. Patient is in regular follow up,having no complain,clinically no neurological dysfunction and no evidence of disease at right parotid and neck region. Thus it was concluded that patients responded well to treatment. Treatment strategies in case of synchronous double malignancy depend on treating the malignancy that is more advanced first or sometimes both could be treated simultaneously. In our case we concluded that synchronous double malignancy may be treated successfully. Both sites should be treated fully as if they were occurring separately considering toxicities.

    2006-12-01

    Due to their geographical mobility and long periods of separation from intimate partners, migrant workers are at increased risk for a variety of sexually transmitted infections (STIs) including HIV/AIDS. This study sought to investigate patterns in HIV/AIDS related knowledge, attitudes and sexual behaviour in migrant workers in Croatia. In 2003, 566 male migrant workers were recruited during regular required medical examinations and surveyed at seven locations throughout the country. Each participant was asked to complete a self-administered KABP (sexual knowledge, attitudes, beliefs and practices) questionnaire. The average age of respondents was 38.2 years and the majority worked as seafarers (77.3%) and construction workers (20.5%). Only 18.5% of respondents were able to correctly answer all 13 questions assessing knowledge of HIV/AIDS. Seafarers reported higher levels of knowledge than did construction workers. The average respondent reported having had two sexual partners in the last 12 months, with slightly over half of the respondents (55.3%) reporting condom use at their last intercourse with a casual partner. One fifth of the respondents (20.3%) who reported having had intercourse with a sex worker during the last year reported not using condoms at last intercourse. The number of sexual partners was correlated with age, marital status, faith in God, and personal HIV risk assessment. Attitudes toward condom use, co-workers' HIV/AIDS concerns and the duration of migrant status (within the last two years) were shown to be significant correlates of condom use at last intercourse with a casual partner. The effect of HIV/AIDS related knowledge on analyzed behaviors did not reach statistical significance. Inadequate patterns of migrant workers' condom use, gaps in knowledge about HIV transmission and modes of protection, as well as widespread ignorance regarding available anonymous HIV testing found by this study suggest a critical need for expert intervention to

    2016-02-01

    Full Text Available Oral malignant melanoma is a rare aggressive neoplasm commonly affects males and is more frequently seen at the level of the hard palate and gingiva. In many cases, melanoma has evolved from the pre-existing pigmented lesions. These neoplasms are biologically aggressive, but they often go unnoticed since they usually present merely as a hyperpigmented patch on the gingival surface. Performing biopsies of doubtful pigmented lesions helps in early treatment and better prognosis. The surgical excision combined with the chemotherapy is the treatment of choice. Here, we report a rare case of an elderly male patient with oral malignant melanoma with metastasis to vertebral column.

    Malignant pleural mesothelioma is a highly invasive tumor arising from the mesothelial cells of serosal surfaces. Several chemotherapeutic agents have been tested for the treatment of this disease and doublet cisplatin with antifolates has been demonstrated to have significant efficacy in Phase III studies. However, the benefit of these treatments remains poor and the median survival time of patients is low, ranging between 9 and 17 months. Targeted therapies are being developed in oncology and emerging evidence suggests that they offer disease control in several tumors. This article reviews the knowledge on the malignant pleural mesothelioma molecular pathway and focuses on results of clinical trials conducted on this devastating disease.

    A 62-year-old man with left chest pain had left pleural effusion pointed out on a chest radiograph. Chest CT scans showed multiple nodules on the left parietal pleura and pleural effusion. He was referred to our hospital and we performed thoracoscopic examination. Malignant pleural mesothelioma (biphasic type) was diagnosed, based on the pathological findings of a parietal nodular mass, including immunohistological analysis. Chemotherapy using carboplatin and pemetrexed reduced the size of tumor and left pleural effusion. This is a rare case with atypical CT findings of malignant pleural mesothelioma.

    Primary malignant pericardial mesothelioma is an exceptionally rare tumor, and making an antemortem diagnosis of this disease is notoriously difficult. We herein report the case of a 61-year-old woman with pericardial mesothelioma who presented with shortness of breath and peripheral edema of the lower limbs. Chest computed tomography (CT) showed an anterior mass and thickened pericardium with multiple pericardial nodules. A biopsy of the mediastinal mass was performed using right thoracotomy, and the histological findings indicated a sarcomatoid tumor. The patient was treated with chemotherapy; however, she but died three months after diagnosis. An autopsy confirmed a final diagnosis of sarcomatoid type primary malignant pericardial mesothelioma following extensive immunohistopathological examinations.

    Full Text Available Interferons (IFNs are a family of cytokines with potent antiproliferative, antiviral, and immunomodulatory properties. Much has been learned about IFNs and IFN-activated signaling cascades over the last 50 years. Due to their potent antitumor effects in vitro and in vivo, recombinant IFNs have been used extensively over the years, alone or in combination with other drugs, for the treatment of various malignancies. This review summarizes the current knowledge on IFN signaling components and pathways that are deregulated in human malignancies. The relevance of deregulation of IFN signaling pathways in defective innate immune surveillance and tumorigenesis are discussed.

    Malignant biliary strictures often present late after the window for curative resection has elapsed. In such patients, the goal of therapy is typically focused on palliation. While historically, palliative measures were performed surgically, the advent of endoscopic intervention offers minimally invasive options to provide relief of symptoms, improve quality of life, and in some cases, increase survival of these patients. Some of these therapies, such as endoscopic biliary decompression, have become mainstays of treatment for decades, whereas newer modalities, including radiofrequency ablation, and photodynamic therapy offer additional options for patients with incurable biliary malignancies.

    2014-12-01

    Stathmin 1 is a microtubule destabilizer that plays an important role in cell cycle progression, segregation of chromosomes, clonogenicity, cell motility and survival. Stathmin 1 overexpression has been reported in malignant hematopoietic cells and Stathmin 1 inhibition reduces the highly proliferative potential of leukemia cell lines. However, during the differentiation of primary hematopoietic cells, Stathmin 1 expression decreases in parallel to decreases in the proliferative potential of early hematopoietic progenitors. The scope of the present review is to survey the current knowledge and highlight future perspectives for Stathmin 1 in normal and malignant hematopoiesis, with regard to the expression, function and clinical implications of this protein.

    Metastatic pancreatic cancer(MPC) is one of the most aggressive malignancies, known to be chemo-resistant and have been recently considered resistant to some targeted therapies(TT). Erlotinib combined to gemcitabine is the only targeted therapy that showed an overall survival benefit in MPC. New targets and therapeutic approaches, based on new-TT, are actually being evaluated in MPC going from immunotherapy, epigenetics, tumor suppressor gene and oncogenes to stromal matrix regulators. We aim in this paper to present the major causes rendering MPC an untargetable malignancy and to focus on the new therapeutic modalities based on TT in MPC.

    An autopsy case of radiation-induced intracranial malignant fibrous histiocytoma (fibroxanthosarcoma) is reported. The tumor developed in the region of the sella turcica 11 years after high dose radiotherapy of a chromophobe adenoma of the pituitary. The tumor had infiltrated the base of the brain as well as the base of the skull. Metastases were not found. The tumor was composed of an admixture of bizarre fibroblasts, histiocytes and giant cells, xanthoma cells and siderophages, with a storiform fibrous stroma. This appears to be the first documented instance of a malignant fibrous histiocytoma occurring intracranially after local x irradiation.

  12. Talking about AIDS

    Directory of Open Access Journals (Sweden)

    2003-09-01

    Full Text Available This paper explores the significance of social relationships to two important stages in the process of sexual behavioral change in response to increased HIV/AIDS risk in rural Africa: the perceived risk of becoming HIV-infected through unprotected sexual intercourse and the preferred methods of protection either through sexual fidelity, or through condom use. The empirical analyses are based on cross-sectional data from the 'Kenyan Diffusion and Ideational Change Project' (KDICP which provides information about AIDS-related, ego-centered communication networks of Kenyan men and women. The results show that perceived risks, as well as preferred methods of protection against HIV-infection, depend in general on the prevailing perceptions and favored protective methods within personal communication networks. However, different influential network properties can be found. The risk-perceptions of women are shaped by strong relationships and cohesive network structures. Male's risk perception depends more on the number of risk-perceivers in their communication networks. Heterogeneous relationships of various kinds are influential on women's and men's probability of favoring sexual faithfulness as a method of protection against HIV-infection.

    1995-08-01

    Malaysia has an estimated population of 18.8 million people. The first AIDS case of Malaysian origin was detected in December 1986. As of April 30, 1995, there were cumulatively 12,122 reported HIV infections and 228 cases of AIDS. Of the 12,122 HIV cases, 78% are attributed to IV drug use, 17% to other unknown routes, and 2% to heterosexual sex. While the Malaysian government's initial anti-AIDS campaign used fear tactics, public campaigns have recently been revised to employ a softer approach, minimizing fear tactics and referring to transmission risks as high-risk behavior. The government's main anti-AIDS strategy has concentrated upon preventing transmission through mass awareness campaigns and motivating behavioral change. Harm reduction measures such as condom distribution remain limited to specific target groups such as people already infected with HIV/AIDS. Syringe and needle exchange activities are not allowed under Malaysia's anti-drug laws. Complementing and supporting the government's anti-AIDS campaign are nongovernmental organizations working upon HIV/AIDS which are affiliated with the Malaysian AIDS Council. The majority of programs concentrate upon basic education and awareness, although some programs provide direct service-oriented activities.

    To evaluate the role of chemical shift MRI in the characterisation of indeterminate skeletal lesions of the spine as benign or malignant. Fifty-five patients (mean age 54.7 years) with 57 indeterminate skeletal lesions of the spine were included in this retrospective study. In addition to conventional MRI at 3 T which included at least sagittal T1WI and T2WI/STIR sequences, patients underwent chemical shift MRI. A cut-off value with a signal drop-out of 20 % was used to differentiate benign lesions from malignant lesions (signal drop-out <20 % being malignant). There were 45 benign lesions and 12 malignant lesions. Chemical shift imaging correctly diagnosed 33 of 45 lesions as benign and 11 of 12 lesions as malignant. In contrast, there were 12 false positive cases and 1 false negative case based on chemical shift MRI. This yielded a sensitivity of 91.7 %, a specificity of 73.3 %, a negative predictive value of 97.1 %, a positive predictive value of 47.8 % and a diagnostic accuracy of 82.5 %. Chemical shift MRI can aid in the characterisation of indeterminate skeletal lesions of the spine in view of its high sensitivity in diagnosing malignant lesions. Chemical shift MRI can potentially avoid biopsy in a considerable percentage of patients with benign skeletal lesions of the spine. (orig.)

    In response to concern over the perceived limited effectiveness of Department of Health and Social Security (UK) advertising campaigns to inform the public of the basic facts of Acquired Immunodeficiency Syndrome (AIDS), a prospective questionnaire study was undertaken in Southampton, England to test the effectiveness of government education prior to a January, 1987 government television/leaflet advertising campaign. 300 questionnaires about AIDS were mailed in December of 1986 to a sample drawn from electoral rolls. The response rate was 61%. Most of the questions were drawn from material covered in the campaign. The results seemed to indicate a small overall increase in knowledge about AIDS. Some changes from a June survey were noted, e.g.: more people were aware that AIDS is a virus for which there is no cure and that it is not readily transmitted by sharing washing, eating or drinking utensils; more people believed that the statement that women are at greater risk for catching AIDS is false. Respondents were generally favorable to the government's continued use of television, even with explicit language, and to its use of the schools, for AIDS education. Many were not aware of the dangers to intravenous drug users or of the symptoms of AIDS. Other surveys have shown an increasing knowledge of AIDS dangers. It is possible that television coverage of the problem will continue to be necessary, in order that less literate populations be reached. Further AIDS health education in general is needed.
