Transient Leukaemia: Leukaemia or Leukaemoid? A Diagnostic Dilemma

We report a case of a newborn male who had mongoloid slant and was hypotonic at birth. Routine investigations revealed leucocytosis (WBC > 70,000/cmm) with 50% blasts in peripheral blood film. Marrow examination confirmed the excess of blasts. Karyotyping revealed 47, XY + 21 chromosomes. Due to absence of clinical symptoms, the baby was kept on follow-up without treatment. Within 7 weeks, PBF and bone marrow findings returned to normal, and the child was diagnosed as having Transient leukaemia with Down syndrome.     

Vascular Endothelial Growth Factor Levels in Childhood Acute Lymphoblastic and Myeloblastic Leukemia

Angiogenesis has been associated with the growth, dissemination and metastasis and has been shown to be a prognostic. Although there are some data suggesting that angiogenesis may have a role in the pathophysiology of leukemia, its role in patient prognosis is yet to be defined. We analyzed the expression level of vascular endothelial growth factor (VEGF), an angiogenesis promoter and its possible- prognostic value in bone marrow samples at the time of diagnosis and remission of acute childhood leukemia patients. Besides 46 patients diagnosed as ALL or AML, 16 children were also included as a control group in the study. Our data have demonstrated that VEGF levels of AML patients were found higher than the control group statistically (P = 0.022). However we could not find any significant difference between VEGF levels of diagnosis and remission in both AML and ALL groups by blastic VEGF expression (P > 0.05). In this study the higher levels of VEGF in AML patients is one of the main findings although we were not able to assess any role of VEGF in predicting prognosis in pediatric leukemia patients by evaluating blastic cell VEGF expression. These results have demonstrated that the relationship between angiogenesis or angiogenesis promoters and hematological malignancies is not clear and simple as different methods or different cells beside different angiogenesis promotors are involved to these studies. So that not only tumor cells and their cytokines but also surrounding cells and their cytokines must be taken into consideration with the standardized study methods in the further studies to obtain a promising treatment approach.     

Therapeutic algorithms for chronic hepatitis C in the DAA era during the current economic crisis: whom to treat? How to treat? When to treat?

The advent of triple therapy (TT) with first-generation protease inhibitors boceprevir (BOC) and telaprevir (TVR) in addition to pegylated interferon and ribavirin resulted in a significant gain in terms of sustained virological response (SVR) when treating naive or previous treated patients with genotype 1 (G1) chronic hepatitis C (CHC). This gain is partly balanced by the increased complexity of treatment and by the raised costs and risks of therapy, making necessary to optimize the indication to TT.Specifically, the identification of patient needing to TT over DT, the choice of the more correct therapeutic approach according to baseline and on treatment SVR predictors, and the timing of antiviral treatment, appear key issues to evaluate when considering TVR or BOC-based therapies.Along this line, further efforts aimed to optimize the current TT regimens are still needed, especially in under-represented groups of patients in phase 3 studies such as those with cirrhosis, where post-marketing data are giving interesting evidences.     

A quick and cost effective method for the diagnosis of <Emphasis Type=Italic>Mycobacterium ulcerans</Emphasis> infection

Background  

Buruli ulcer (BU), a neglected tropical skin disease caused by Mycobacterium ulcerans, has been reported in over 30 countries worldwide and is highly endemic in rural West and Central Africa. The mode of transmission remains unknown and treatment is the only alternative to disease control. Early and effective treatment to prevent the morbid effects of the disease depends on early diagnosis; however, current diagnosis based on clinical presentation and microscopy has to be confirmed by PCR and other tests in reference laboratories. As such confirmed BU diagnosis is either late, inefficient, time consuming or very expensive, and there is the need for an early diagnosis tool at point of care facilities. In this paper we report on a simple, quick and inexpensive diagnostic test that could be used at point of care facilities, in resource-poor settings.     

Campagne de vaccination hors centre contre la rougeole des populations précaires en période de pic épidémique,Marseille 2011

BackgroundFrom 2008 to the end of 2011, Europe experienced a major outbreak of measles. The outbreak hit France especially hard, with measles hotspots in the South-East of France. It is known that people living in precarious socio-economic conditions are more exposed to infectious diseases. Regarding the local situation, the NGO “MdM-Marseille” decided to conduct a vaccination campaign among the Roma community living in camps.MethodsThe campaign was planned with two injections of a combined measles, mumps and rubella vaccine (MMR) in a one month interval for all young people born since 1980 and over the age of one year, regardless of antecedents. Twenty-four camps were selected. The target population was estimated at 720 people. Each site was the subject of an information visit. A letter was sent to the Prefecture to inform them and ask for a moratorium on evictions for the identified camps.ResultsBetween May 15th and September 15th 2011, 326 primary immunizations were performed during 34 visits (covering 45.3% of the target population). Over the same period, almost all the camps were evacuated, forcing teams to stop the vaccination campaign. The second injection campaign covered only 37 persons.ConclusionThe vaccination campaign among Roma populations in Marseilles was organized in a context of a major national outbreak of measles in the general population. Although the Prefecture was informed, camp evictions were not interrupted. This highlights the discrepancy between public health policy and security policy. In the context of an epidemic, innovative actions should be focused on vulnerable populations in partnership with health authorities. The main objective is to find procedures that can protect populations at risk in the event of a health crisis but which are also useful for routine prevention.     

Transitional Care Coordination in New York City Jails: Facilitating Linkages to Care for People with HIV Returning Home from Rikers Island

New York City (NYC) jails are the epicenter of an epidemic that overwhelmingly affects Black and Hispanic men and offer a significant opportunity for public health intervention. The NYC Department of Health and Mental Hygiene instituted population based approaches to identify the HIV-infected, initiate discharge planning at jail admission, and facilitate post-release linkages to primary care. Using a caring and supportive ‘warm transitions’ approach, transitional care services are integral to continuity of care. Since 2010, over three-quarters of known HIV-infected inmates admitted to jails received discharge plans; 74 % of those released were linked to primary care. The EnhanceLink initiative’s new Health Liaison, a lynchpin role, facilitated 250 court-led placements in medical alternatives to incarceration. Transitional care coordination programs are critical to facilitate continuity of care for people with chronic health conditions including the HIV-infected returning home from jail and for the public health of the communities to which they return.     

Why MSM in Rural South African Communities Should be an HIV Prevention Research Priority

Research into HIV and men who have sex with men’s (MSM) health in South Africa has been largely confined to the metropolitan centres. Only two studies were located making reference to MSM in rural contexts or same-sex behaviors among men in the same. There is growing recognition in South Africa that MSM are not only disproportionately affected by HIV and have been underserved by the country’s national response, but that they contribute significantly to sustaining the high number of new infections recorded each year. We argue that to meet the objectives of the country’s national strategic plan for HIV, STI and TB it is important we know how these behaviours may be contributing to the sustained rural HIV epidemic in the youngest age groups and determine what constitutes appropriate and feasible programmatic response that can be implemented in the country’s public sector health services.     

Functional asymmetries in early learning during right,left, and bimanual performance in right‐handed subjects

Purpose:

To elucidate differences in activity and connectivity during early learning due to the performing hand.

Materials and Methods:

Twenty right‐handed subjects were recruited. The neural correlates of explicit visuospatial learning executed with the right, the left hand, and bimanually were investigated using functional magnetic resonance imaging. Connectivity analyses were carried out using the psychophysiological interactions model, considering right and left anterior putamen as index regions.

Results:

A common neural network was found for the three tasks during learning. Main activity increases were located in posterior cingulate cortex, supplementary motor area, parietal cortex, anterior putamen, and cerebellum (IV–V), whereas activity decrements were observed in prefrontal regions. However, the left hand task showed a greater recruitment of left hippocampal areas when compared with the other tasks. In addition, enhanced connectivity between the right anterior putamen and motor cortical and cerebellar regions was found for the left hand when compared with the right hand task.

Conclusion:

An additional recruitment of brain regions and increased striato‐cortical and striato‐cerebellar functional connections is needed when early learning is performed with the nondominant hand. In addition, access to brain resources during learning may be directed by the dominant hand in the bimanual task. J. Magn. Reson. Imaging 2013;37:619–631. © 2012 Wiley Periodicals, Inc.     

The HPV Vaccine: A Comparison of Focus Groups Conducted in South Africa and Ohio Appalachia

Worldwide, cervical cancer is one of the leading causes of morbidity and mortality among women. Even though women in developing countries account for approximately 85 % of the cervical cancer cases and deaths, disparities in cervical cancer rates are also documented in developed countries like the United States (U.S.). Recently, formative research conducted in the U.S. and developing countries like South Africa have sought to gain a better understanding of the knowledge, beliefs, and attitudes about cervical cancer prevention, HPV, and the acceptance of the HPV vaccine. This study compares findings from two independent focus group studies. One study was conducted in a segregated township in Johannesburg, South Africa (n = 24) and the other study was conducted in Ohio Appalachia (n = 19). The following seven themes emerged during the discussions from both studies: HPV and cervical cancer; health decision making; parent–child communication; healthy children; HPV vaccine costs; sexual abuse; and HPV vaccine education. Findings from both studies indicate the importance of the role of mothers and grandmothers in the health care decision-making process for children and a lack of awareness of HPV and its association with cervical cancer. While there was interest in the HPV vaccine, participants voiced concern about the vaccine’s cost and side effects. Some participants expressed concern that receipt of the HPV vaccine may initiate adolescent sexual behavior. However, other participants suggested that the HPV vaccine may protect young women who may experience sexual abuse. The importance of developing culturally appropriate educational materials and programs about cervical cancer prevention and the HPV vaccine were expressed by participants in both countries.     

Urban Health Challenges in Europe

This article synthesizes diverse official reports, statistics, and scientific papers that present demographic, economic, environmental, and social trends impacting on the health and quality of life of citizens living in European cities. A literature review led to the identification of some key challenges including an aging society, migration flows, inequalities in health, global change, and risk behaviors that should be addressed in order to promote urban health. Other challenges, such as food production and consumption, are also relevant, but not included. Cities that have participated in one or more of the phases of the WHO European Healthy Cities Network have implemented a number of policies, programs, and measures to deal with the challenges discussed in this article. Some contributions are presented to illustrate how health and quality of life in urban areas can be promoted by local authorities.
