    Timely vaccinations decrease a child's risk of contracting vaccine-preventable disease and prevent disease outbreaks. Childhood immunization schedules may represent the only clinical guideline for which there is official national consensus. So an immunization clinical decision support system (CDSS) is a natural application. However, immunization schedules are complex and change frequently. Maintaining multiple CDSS's is expensive and error prone. Therefore, a practical strategy would be an immunization CDSS as a centralized web service that can be easily accessed by various electronic medical record (EMR) systems. This allows centralized maintenance of immunization guidelines. We have developed a web service, based on Miller's tabular model with modifications, which implements routine childhood immunization guidelines. This immunization web service is currently operating in the Regenstrief Institute intranet and system evaluations are ongoing. We will make this web service available on the Internet. In this paper, we describe this web service -based immunization decision support tool.

    Improving childhood vaccination coverage and timeliness is a key health policy objective in many developing countries such as Uganda. Of the many factors known to influence uptake of childhood immunizations in under resourced settings, parents' understanding and perception of childhood immunizations has largely been overlooked. The aims of this study were to survey mothers' knowledge and attitudes towards childhood immunizations and then determine if these variables correlate with the timely vaccination coverage of their children. From September to December 2013, we conducted a cross-sectional survey of 1,000 parous women in rural Sheema district in southwest Uganda. The survey collected socio-demographic data and knowledge and attitudes towards childhood immunizations. For the women with at least one child between the age of one month and five years who also had a vaccination card available for the child (N = 302), the vaccination status of this child was assessed. 88% of these children received age-appropriate, on-time immunizations. 93.5% of the women were able to state that childhood immunizations protect children from diseases. The women not able to point this out were significantly more likely to have an under-vaccinated child (PR 1.354: 95% CI 1.018-1.802). When asked why vaccination rates may be low in their community, the two most common responses were "fearful of side effects" and "ignorance/disinterest/laziness" (44% each). The factors influencing caregivers' demand for childhood immunizations vary widely between, and also within, developing countries. Research that elucidates local knowledge and attitudes, like this study, allows for decisions and policy pertaining to vaccination programs to be more effective at improving child vaccination rates.

    Immune thrombocytopenia (ITP) is an acquired hematological disorder that is developed secondary to the production of auto-antibodies against platelets leading to isolated thrombocytopenia, in the absence of other causes of thrombocytopenia such as drugs, infections, malignancy, or other autoimmune diseases [1–6]. ITP commonly affects children between one and seven years of age. Severe life threatening bleeding is rare (0.2–0.9%) [7–12]. Childhood primary ITP usually runs a benign, self-limiti...

    Full Text Available Background : The main service provider for childhood immunization in Sri Lanka is the government sector. However, utilization of private sector for childhood immunization is increasing rapidly. Existing national immunization data does not routinely include statistics on private sector immunization delivery adequately. Objective : To estimate the proportion of children immunized in the private sector; describe socio-demographic characteristics of private sector users and compare these with government sector users. Materials and Methods : A community-based crosssectional descriptive study was conducted using a pre-tested interviewer-administered structured questionnaire. This was done in the Colombo municipal council area using the WHO 30 cluster methodology. The total number of households in the sample was 553. Results : Out of the 5,028 total immunizations reported in the present study, around one-third (2,544 was obtained through the private sector. Nineteen percent (104 of children were exclusively immunized from the private sector. The distribution of usual immunization provider was - government sector 72.3% (400 and private sector 27.7% (153. Significant differences were observed (P < 0.001 between private and government sector users with regard to family income, social class, ethnicity, religion and educational level of the mother. The age-appropriate immunization among the 12- to 23-month age group was 92.3% (144 in the government sector, whereas it was 95% (38 in the private sector. Among the 24- to 35-month age group, it was 91.7% (121 and 92.7% (76 respectively. The age-adjusted immunization coverage rates were almost same among the government and private sector users except for the measles vaccine, where the private sector users had significantly (P = 0.016 higher coverage. Conclusions :Utilization of private sector immunization services is high in the Colombo municipal council area.

    While correlations between maternal education and child health have been observed in diverse parts of the world, the causal pathways explaining how maternal education improves child health remain far from clear. Using data from the nationally representative India Human Development Survey of 2004-5, this analysis examines four possible pathways that may mediate the influence of maternal education on childhood immunization: greater human, social, and cultural capitals and more autonomy within the household. Data from 5287 households in India show the familiar positive relationship between maternal education and childhood immunization even after extensive controls for socio-demographic characteristics and village- and neighborhood-fixed effects. Two pathways are important: human capital (health knowledge) is an especially important advantage for mothers with primary education, and cultural capital (communication skills) is important for mothers with some secondary education and beyond.

  9. Childhood immune thrombocytopenia: role of rituximab, recombinant thrombopoietin, and other new therapeutics.

    2012-01-01

    Childhood immune thrombocytopenia (ITP) is often considered a benign hematologic disorder. However, 30% of affected children will have a prolonged course and 5%-10% will develop chronic severe refractory disease. Until recently, the only proven therapeutic option for chronic severe ITP was splenectomy, but newer alternatives are now being studied. However, because immunosuppressive agents such as rituximab are not approved for use in ITP and the thrombopoietin receptor agonists are not yet approved in children, the decision to use alternatives to splenectomy needs to be considered carefully. This review describes the factors that should affect decisions to treat ITP at diagnosis and compares the options for the occasional child in whom ITP does not resolve within the first year.

    OBJECTIVE To analyze the sociocultural aspects involved in the decision-making process of vaccination in upper-class and highly educated families. METHODS A qualitative approach based on in-depth interviews with 15 couples from the city of Sao Paulo, Southeastern Brazil, falling into three categories: vaccinators, late or selective vaccinators, and nonvaccinators. The interpretation of produced empirical material was performed through content analysis. RESULTS The study showed diverse and particular aspects surrounding the three groups' decisions whether to vaccinate their children. The vaccinators' decision to vaccinate their children was spontaneous and raised no questions. Most late or selective vaccinators experienced a wide range of situations that were instrumental in the decision to delay or not apply certain vaccines. The nonvaccinator's decision-making process expressed a broader context of both criticism of hegemonic obstetric practices in Brazil and access to information transmitted via social networks and the internet. The data showed that the problematization of vaccines (culminating in the decision to not vaccinate their children) occurred in the context of humanized birth, was protagonized by women and was greatly influenced by health information from the internet. CONCLUSIONS Sociocultural aspects of the singular Brazilian context and the contemporary society were involved in the decision-making on children's vaccination. Understanding this process can provide a real basis for a deeper reflection on health and immunization practices in Brazil in light of the new contexts and challenges of the world today.

    2005-12-01

    Over the past 150 years, innovations in immunization practices have dramatically improved the health of children, and parents are increasingly asked to consider and accept new childhood vaccines. We present a conceptual model to frame a review of research on the role of parental attitudes and beliefs in decision making about child and adolescent immunization and describe the historical context of vaccine-related decision-making research. This review focuses on theory-based Social-environmental and parent-specific personal factors as potential influences on vaccine decision making. Relevant Social-environmental issues discussed include media coverage of vaccines, perceived social norms, and the persuasive influence of peer groups. Health care provider recommendations are presented as an exemplar of factors related to the family's interface with the health care system. Personal factors addressed include parental health beliefs, attitudes, and knowledge related to vaccine preventable diseases and immunization, as well as cognitive heuristics that are employed in the decision-making process (e.g., omission bias, protected values, framing of information). Last, promising directions for research and suggestions for clinical practice are presented.

    The associations between childhood acute lymphoblastic leukemia (ALL) and several proxies of early stimulation of the immune system, that is, day-care center attendance, birth order, maternally reported common infections in infancy, and breastfeeding, were investigated by using data from 11 case-control studies participating in the Childhood Leukemia International Consortium (enrollment period: 1980-2010). The sample included 7,399 ALL cases and 11,181 controls aged 2-14 years. The data were collected by questionnaires administered to the parents. Pooled odds ratios and 95% confidence intervals were estimated by unconditional logistic regression adjusted for age, sex, study, maternal education, and maternal age. Day-care center attendance in the first year of life was associated with a reduced risk of ALL (odds ratio = 0.77, 95% confidence interval: 0.71, 0.84), with a marked inverse trend with earlier age at start (P < 0.0001). An inverse association was also observed with breastfeeding duration of 6 months or more (odds ratio = 0.86, 95% confidence interval: 0.79, 0.94). No significant relationship with a history of common infections in infancy was observed even though the odds ratio was less than 1 for more than 3 infections. The findings of this large pooled analysis reinforce the hypothesis that day-care center attendance in infancy and prolonged breastfeeding are associated with a decreased risk of ALL.

    The association between childhood immunizations and risk of atopic diseases is unclear. No study has examined possible associations between childhood immunizations and such diseases in middle age. The Tasmanian Longitudinal Health Study (TAHS) is a population based cohort study of respiratory disease. The TAHS participants were followed from 7 to 44 yrs of age. Immunizations during childhood were examined for any association with asthma and atopic disease at age 44 yrs. Multivariable regression models were used to estimate relative risks while adjusting for confounders. Cox regression was used to estimate the association between childhood immunizations and asthma developing after the age of 7 yrs. We found no association between any childhood immunization (Diphtheria, Tetanus, Pertussis, Polio, Smallpox) and asthma (ORs ranged from 0.87 to 1.17 p > 0.05), eczema (ORs ranged from 0.99 to 1.07 p > 0.05), food allergy (ORs ranged from 0.97 to 1.11 p > 0.05), or hay fever (ORs ranged from 1.02 to 1.05 p > 0.05) at age 44. Nor did we find any association between childhood immunizations and an increased risk of incident asthma after the age of 7 yrs (Diphtheria HR = 1.06, 95% CI 0.82, 1.36; Tetanus HR = 1.13, 95% CI 0.88, 1.44; Pertussis HR = 1.03, 95% CI 0.81, 1.30; Polio HR = 1.15, 95% CI 0.86, 1.54; Smallpox HR = 1.21, 95% CI 0.99, 1.48; DTP HR = 1.05, 95% CI 0.85, 1.30). Our analysis does not support any association between common childhood immunizations and risk of asthma and atopic disease in middle-age. Our findings should provide reassurance that in terms of life time risk of asthma and atopic disease, childhood immunization is safe.

    Although it has been thought that child immunization programs may miss the children who are in greatest need, there are little published quantitative data to support this idea. We sought to characterize malnutrition and morbidity among children who are missed by the childhood immunization program in Indonesia. Vaccination and morbidity histories, anthropometry, and other data were collected for 286,500 children, aged 12-59 months, in rural Indonesia. Seventy-three point nine percent of children received complete immunizations (3 doses of diphtheria-pertussis-tetanus, 3 doses of oral poliovirus, and measles), 16.8% had partial coverage (1-6 of 7 vaccine doses), and 9.3% received no vaccines. Of children with complete, partial, and no immunization coverage, respectively, the prevalence of severe underweight (weight-for-age Z score childhood immunizations in rural Indonesia, as missed children are at higher risk of morbidity and mortality.

    Among 4380 children born in 1987-1997 of women with a diagnosis of diabetes and alive at the age of one, 10 were registered in the Swedish Cancer Registry before the end of 1998. The odds ratio for having a childhood cancer after maternal diabetes, stratified for year of birth, maternal age, parity, multiple birth, and 500 g birth weight class was 2.25 (95%CI 1.22-4.15). Among 5842 children born during the period 1973-1997 whose mothers had other auto-immune diseases (SLE, rheumatoid arthritis, Crohn, ulcerous colitis, multiple sclerosis or thyroiditis), the number of observed childhood cancers (9) was close to that expected (8.5). Maternal diabetes but not other auto-immune diseases may be a risk factor for childhood cancer.

    This study seeks to understand whether poverty very early in life is associated with early-onset adult conditions related to immune-mediated chronic diseases. It also tests the role that these immune-mediated chronic diseases may play in accounting for the associations between early poverty and adult productivity. Data (n = 1,070) come from the US Panel Study of Income Dynamics and include economic conditions in utero and throughout childhood and adolescence coupled with adult (age 30-41 y) self-reports of health and economic productivity. Results show that low income, particularly in very early childhood (between the prenatal and second year of life), is associated with increases in early-adult hypertension, arthritis, and limitations on activities of daily living. Moreover, these relationships and particularly arthritis partially account for the associations between early childhood poverty and adult productivity as measured by adult work hours and earnings. The results suggest that the associations between early childhood poverty and these adult disease states may be immune-mediated.

    OBJECTIVE To analyze the costs of vaccination regimens for introducing inactivated polio vaccine in routine immunization in Brazil. METHODS A cost analysis was conducted for vaccines in five vaccination regimens, including inactivated polio vaccine, compared with the oral polio vaccine-only regimen. The costs of the vaccines were estimated for routine use and for the "National Immunization Days", during when the oral polio vaccine is administered to children aged less than five years, independent of their vaccine status, and the strategic stock of inactivated polio vaccine. The presented estimated costs are of 2011. RESULTS The annual costs of the oral vaccine-only program (routine and two National Immunization Days) were estimated at US$19,873,170. The incremental costs of inclusion of the inactivated vaccine depended on the number of vaccine doses, presentation of the vaccine (bottles with single dose or ten doses), and number of "National Immunization Days" carried out. The cost of the regimen adopted with two doses of inactivated vaccine followed by three doses of oral vaccine and one "National Immunization Day" was estimated at US$29,653,539. The concomitant replacement of the DTPw/Hib and HepB vaccines with the pentavalent vaccine enabled the introduction of the inactivated polio without increasing the number of injections or number of visits needed to complete the vaccination. CONCLUSIONS The introduction of the inactivated vaccine increased the annual costs of the polio vaccines by 49.2% compared with the oral vaccine-only regimen. This increase represented 1.13% of the expenditure of the National Immunization Program on the purchase of vaccines in 2011.

    2003-01-01

    The diagnosis, treatment, and side effects of childhood cancer have been described as extremely stressful experiences in the life of a child. Anecdotally, children report that a sense of humor helps them cope with the daily experiences of living with cancer; however, no research has examined sense of humor and childhood cancer stressors. This study investigated the effect of sense of humor on the relationship between cancer stressors and children's psychosocial adjustment to cancer, immune function, and infection using Lazarus and Folkman's theory of stress, appraisal, and coping. A direct relationship was observed between sense of humor and psychosocial adjustment to cancer, such that children with a high sense of humor had greater psychological adjustment, regardless of the amount of cancer stressors. A moderating effect was observed for incidence of infection. As childhood cancer stressors increase, children with high coping humor scores reported fewer incidences of infection than low scorers.

    2007-12-01

    Full Text Available Abstract Background Sierra Leone has undergone a decade of civil war from 1991 to 2001. From this period few data on immunization coverage are available, and conflict-related delays in immunization according to the Expanded Programme on Immunization (EPI schedule have not been investigated. We aimed to study delays in childhood immunization in the context of civil war in a Sierra Leonean community. Methods We conducted an immunization survey in Kissy Mess-Mess in the Greater Freetown area in 1998/99 using a two-stage sampling method. Based on immunization cards and verbal history we collected data on immunization for tuberculosis, diphtheria, tetanus, pertussis, polio, and measles by age group (0–8/9–11/12–23/24–35 months. We studied differences between age groups and explored temporal associations with war-related hostilities taking place in the community. Results We included 286 children who received 1690 vaccine doses; card retention was 87%. In 243 children (85%, 95% confidence interval (CI: 80–89% immunization was up-to-date. In 161 of these children (56%, 95%CI: 50–62% full age-appropriate immunization was achieved; in 82 (29%, 95%CI: 24–34% immunization was not appropriate for age. In the remaining 43 children immunization was partial in 37 (13%, 95%CI: 9–17 and absent in 6 (2%, 95%CI: 1–5. Immunization status varied across age groups. In children aged 9–11 months the proportion with age-inappropriate (delayed immunization was higher than in other age groups suggesting an association with war-related hostilities in the community. Conclusion Only about half of children under three years received full age-appropriate immunization. In children born during a period of increased hostilities, immunization was mostly inappropriate for age, but recommended immunizations were not completely abandoned. Missing or delayed immunization represents an additional threat to the health of children living in conflict areas.

    2011-03-01

    Few researchers have studied how parents from diverse family structures cope with childhood chronic illness. We designed this study to discern the childhood cancer treatment decision-making (TDM) process in these families. Using grounded theory, we interviewed 15 custodial parents, nonresidential parents, and stepparents who had previously made a major treatment decision for their children with cancer. "Moving to place" was the central psychosocial process by which parents negotiated involvement in TDM. Parents moved toward or were moved away from involvement based on parent position in the family (custodial, nonresidential, and stepparent), prediagnosis family dynamics, and time since diagnosis. Parents used the actions of stepping up, stepping back, being pushed, and stepping away to respond to the need for TDM. Parents faced additional stressors because of their family situations, which affected the TDM process. Findings from this study provide important insight into diverse families and their unique parental TDM experiences.

  6. Use of thrombopoietin receptor agonists in childhood immune thrombocytopenia

    2015-08-01

    Full Text Available Most children with immune thrombocytopenia (ITP will have spontaneous remission regardless of therapy, while about 20% will go on to have chronic ITP. In those children with chronic ITP who need treatment, standard therapies for acute ITP may have adverse effects that complicate their long term use. Thus, alternative treatment options are needed for children with chronic ITP. Thrombopoietin receptor agonists (TPO-RA have been shown to be safe and efficacious in adults with ITP, and represent a new treatment option for children with chronic ITP. One TPO-RA, eltrombopag, is now approved for children. Clinical trials in children are ongoing and data is emerging on safety and efficacy. This review will focus on the physiology of TPO-RA, their clinical use in children, as well as the long term safety issues that need to be considered when using these agents

  7. Determinants of Childhood Immunization Uptake among Socio-Economically Disadvantaged Migrants in East China

    2013-07-01

    Full Text Available Objective: To determine the coverage of childhood immunization appropriate for age among socio-economically disadvantaged recent migrants living in East China and to identify the determinants of full immunization uptake among these migrant children. Methods: This is a cross-sectional survey of 1,426 migrant mothers with a child aged ≤24 months, who were interviewed with a pretested questionnaire. Various vaccines, migration history and some other social-demographic and income details were collected. Single-level logistic regression analyses were applied to identify the determinants of full immunization status. Results: Immunization coverage rates are lower among migrants and even lower among recent migrants. The likelihood of a child receiving full immunization rise with parents’ educational level and the frequency of mother’s utilization of health care. Higher household income also significantly increase the likelihood of full immunization, as dose post-natal visits by a health worker. Conclusions: Recent migrant status favours low immunization uptake, particularly in the vulnerability context of alienation and livelihood insecurity. Services must be delivered with a focus on recent migrants. Investments are needed in education, socio-economic development and secure livelihoods to improve and sustain equitable health care services.

    2016-11-08

    A comparative descriptive study was conducted to determine the effectiveness of text messages with pictures compared with plain text messages or verbal reminders in improving measles, mumps, and rubella immunization compliance in the rural areas of the Philippines. We found that text messaging with or without pictures is a feasible and useful tool in measles, mumps, rubella immunization compliance for childhood immunization. Texting with pictures (n = 23), however, was no more effective than plain text messaging (n = 19) or verbal reminder (n = 17) in improving measles, mumps, and rubella immunization compliance. Compared with parents who received verbal reminders alone, either type of text reminders was linked to parents bringing their child for measles, mumps, and rubella immunization on a timelier basis, as defined by the difference between the scheduled visit and the actual visit, although this was not statistically significant. Mobile technology that uses text reminders for immunization can potentially improve the communication process between parent, the public health nurse, and healthcare provider. Future studies can explore the application of plain text messages or text messages with pictures to improve compliance more broadly for maternal and child healthcare especially in rural areas of developing countries and may be a helpful tool for health promotion for this population.

    Despite high vaccine coverage in the United States in general, and in the State of Florida specifically, some children miss scheduled vaccines due to health system failures or vaccine refusal by their parents. Recent experiences with outbreaks in the United States suggest that geographic clustering of un(der)vaccinated populations represent a threat to the elimination status of some vaccine-preventable diseases. Immunization registries continue to expand and play an important role in efforts to track vaccine coverage and use. Using nearly 700,000 de-identified immunization records from the Florida Department of Health immunization information system (Florida SHOTS™) for children born during 2003-2014, we explored heterogeneity and potential clustering of un(der)vaccinated children in six counties in central Florida-Brevard, Lake, Orange, Oseola, Polk, and Seminole-that represent a high-risk area for importation due to family tourist attractions in the area. By zip code, we mapped the population density, the percent of children with religious exemptions, the percent of children on track or overdue for each vaccine series without and with exemptions, and the numbers of children with no recorded dose of each vaccine. Overall, we found some heterogeneity in coverage among the counties and zip codes, but relatively consistent and high coverage. We found that some children with an exemption in the system received the vaccines we analyzed, but exemption represents a clear risk factor for un(der)immunization. We identified many challenges associated with using immunization registry data for spatial analysis and potential opportunities to improve registries to better support future analyses.

    Modified Vaccinia virus has been shown to be a safe and immunogenic vector platform for delivery of HIV vaccines. Use of this vector is of particular importance to the military, with the implementation of a large scale smallpox vaccination campaign in 2002 in active duty and key civilian personnel in response to potential bioterrorist activities. Humoral immunity to smallpox vaccination was previously shown to be long lasting (up to 75 years) and protective. However, using vaccinia-vectored vaccine delivery for other diseases on a background of anti-vector antibodies (i.e. pre-existing immunity) may limit their use as a vaccine platform, especially in the military. In this pilot study, we examined the durability of vaccinia antibody responses in adult primary vaccinees in a healthy military population using a standard ELISA assay and a novel dendritic cell neutralization assay. We found binding and neutralizing antibody (NAb) responses to vaccinia waned after 5-10 years in a group of 475 active duty military, born after 1972, who were vaccinated as adults with Dryvax®. These responses decreased from a geometric mean titer (GMT) of 250 to baseline (vaccination. This contrasted with a comparator group of adults, ages 35-49, who were vaccinated with Dryvax® as children. In the childhood vaccinees, titers persisted for >30 years with a GMT of 210 (range 112-3234). This data suggests limited durability of antibody responses in adult vaccinees compared to those vaccinated in childhood and further that adult vaccinia recipients may benefit similarly from receipt of a vaccinia based vaccine as those who are vaccinia naïve. Our findings may have implications for the smallpox vaccination schedule and support the ongoing development of this promising viral vector in a military vaccination program.

    In vitro amplified human leukocyte antigen (HLA)-haploidentical donor immune cellinfusion (HDICI) is not commonly used in children. Therefore, our study sought to evaluate its safety for treating childhood malignancies. Between September 2011 and September 2012, 12 patients with childhood malignancies underwent HDICI in Sun Yat-sen University Cancer Center. The median patient age was 5.1 years (range, 1.7-8.4 years). Of the 12 patients, 9 had high-risk neuroblastoma (NB) [7 showed complete response (CR), 1 showed partial response (PR), and 1 had progressive disease (PD) after multi-modal therapies], and 3 had Epstein-Barr virus (EBV)-positive lymphoproliferative disease (EBV-LPD). The 12 patients underwent a total of 92 HDICIs at a mean dose of 1.6×108 immune cells/kg body weight: 71 infusions with natural kil er (NK) cells, 8 with cytokine-induced kil er (CIK) cells, and 13 with cascade primed immune cells (CAPRIs); 83 infusions with immune cells from the mothers, whereas 9 with cells from the fathers. Twenty cases (21.7%) of fever, including 6 cases (6.5%) accompanied with chil s and 1 (1.1%) with febrile convulsion, occurred during infusions and were al eviated after symptomatic treatments. Five cases (5.4%) of mild emotion changes were reported. No other adverse events occurred during and after the completion of HDIDIs. Neither acute nor chronic graft versus host disease (GVHD) was observed following HDICIs. After a median of 5.0 months (range, 1.0-11.5 months) of follow-up, the 2 NB patients with PR and PD developed PD during HDICIs. Of the other 7 NB patients in CR, 2 relapsed in the sixth month of HDICIs, and 5 maintained CR with disease-free survival (DFS) ranging from 4.5 to 11.5 months (median, 7.2 months). One EBV-LPD patient achieved PR, whereas 2 had stable disease (SD). Our results show that HDICI is a safe immunotherapy for childhood malignancies, thus warranting further studies.

    PURPOSE: In 2009, human papillomavirus (HPV) vaccination was introduced in the Danish national childhood immunization program targeting all 12-year-old girls. Previous findings suggest that 10%-13% of girls born in 1996-1997 have not initiated vaccination despite free access. This study aims...... to identify socioeconomic predictors of initiation and completion of HPV vaccination. METHODS: Girls born in 1996-1997 and their guardians were identified through the Danish Civil Registration System. Information on socioeconomic variables and HPV vaccination status was obtained by linkage to Statistics...... Denmark and the Danish National Health Insurance Service Register. Through logistic regression, we examined associations between socioeconomic variables and HPV vaccine initiation (N = 65,926) and completion (N = 61,162). RESULTS: Girls with immigrant ethnicity (odds ratio [OR] = .49; 95% confidence...

  13. The etiology of childhood immune thrombocytopenic purpura: how complex is it?

    2003-12-01

    Recent developments in genomics and basic immunology have provided a new set of tools for investigation into the etiology and treatment of childhood immune thrombocytopenia purpura (ITP). The genomic revolution is generating a catalog of germ-line common genetic variants, some of which could influence the susceptibility or outcome of ITP. Similarly, in vitro analyses and animal models have been employed to probe the basic alterations underlying ITP. The emergence of a more refined understanding of complex diseases such as ITP has important implications for prevention, therapy, and follow-up. The relative contribution of the genetic component and its interaction with the strong environmental stimulus, such as an acute, antecedent viral infection, remains to be determined.

  14. Do early childhood immunizations influence the development of atopy and do they cause allergic reactions?

    Science.gov (United States)

    Grüber, C; Nilsson, L; Björkstén, B

    2001-12-01

    Concerns about allergic side-effects of vaccines and about a possible promotion of allergic diseases contribute to incomplete vaccination rates in childhood. This article reviews the current understanding of these issues. There is evidence that pertussis and diphtheria/tetanus antigens elicit immunoglobulin E (IgE) antibody formation as part of the immune response. In murine models, pertussis toxin is an effective adjuvant for IgE formation against simultaneously administered antigens. In children, however, sensitization to unrelated antigens or development of allergic diseases do not seem to be augmented. In contrast, bacille Calmette-Guérin (BCG) and measles vaccination have been proposed as suppressors of allergy because of their T helper 1 (Th1)-fostering properties. In the murine system, BCG inhibits allergic sensitization and airway hyper-reactivity. Some epidemiological studies in humans suggest an inhibitory effect of tuberculosis on allergy. BCG vaccination in children, however, has no or merely a marginal suppressive effect on atopy. Other vaccine components such as egg proteins, gelatin, and antibiotics are a potential hazard to children with severe clinical reactions to these allergens. These rare children should be vaccinated under special precautions. In conclusion, vaccination programs do not explain the increasing prevalence of allergic diseases, but individual children may uncommonly develop an allergic reaction to a vaccine. The risks of not vaccinating children, however, far outweigh the risk for allergy. Therefore, childhood vaccination remains an essential part of child health programs and should not be withheld, even from children predisposed for allergy.

    Wu, Jun; Cheng, Yifei; Zhang, Leping

    2015-12-01

    This retrospective single-center study assessed the incidence and clinical features of immune manifestations of refractory cytopenia of childhood (RCC) and childhood aplastic anemia (AA). We evaluated 72 children with RCC and 123 with AA between February 2008 and March 2013. RCC was associated with autoimmune disease in 4 children, including 1 case each with autoimmune hemolytic anemia, rheumatoid arthritis, systemic lupus erythematosus, and anaphylactoid purpura. No children with AA were diagnosed with autoimmune diseases. Immune abnormalities were common in both RCC and AA; the most significant reductions were in the relative numbers of CD3-CD56+ subsets found in RCC. Despite the many similar immunologic abnormalities in AA and RCC, the rate of autoimmune disease was significantly lower in childhood AA than RCC (p=0.008, χ2=6.976). The relative numbers of natural killer cells were significantly lower in RCC patients than AA patients. By month 6, there was no significant difference in autoimmune manifestations between RCC and AA in relation to the response to immunosuppressive therapy (p=0.907, χ2=0.014). The large overlap of analogous immunologic abnormalities indicates that RCC and childhood AA may share the same pathogenesis.

    Full Text Available Neuroblastoma (NB is a common malignancy in children but rarely occurs during adolescence or adulthood. This subgroup is characterized by an indolent disease course, almost uniformly fatal, yet little is known about the biologic characteristics. The aim of this study was to identify differential features regarding DNA copy number alterations, α-thalassemia/mental retardation syndrome X-linked (ATRX protein expression, and the presence of tumor-associated inflammatory cells. Thirty-one NB patients older than 10 years who were included in the Spanish NB Registry were considered for the current study; seven young and middle-aged adult patients (range 18-60 years formed part of the cohort. We performed single nucleotide polymorphism arrays, immunohistochemistry for immune markers (CD4, CD8, CD20, CD11b, CD11c, and CD68, and ATRX protein expression. Assorted genetic profiles were found with a predominant presence of a segmental chromosome aberration (SCA profile. Preadolescent and adolescent NB tumors showed a higher number of SCA, including 17q gain and 11q deletion. There was also a marked infiltration of immune cells, mainly high and heterogeneous, in young and middle-aged adult tumors. ATRX negative expression was present in the tumors. The characteristics of preadolescent, adolescent, young adult, and middle-aged adult NB tumors are different, not only from childhood NB tumors but also from each other. Similar examinations of a larger number of such tumor tissues from cooperative groups should lead to a better older age–dependent tumor pattern and to innovative, individual risk-adapted therapeutic approaches for these patients.

  19. Artificial Immune Systems (AIS) - A New Paradigm for Heuristic Decision Making

    Uwe, Aickelin

    2008-01-01

    Over the last few years, more and more heuristic decision making techniques have been inspired by nature, e.g. evolutionary algorithms, ant colony optimisation and simulated annealing. More recently, a novel computational intelligence technique inspired by immunology has emerged, called Artificial Immune Systems (AIS). This immune system inspired technique has already been useful in solving some computational problems. In this keynote, we will very briefly describe the immune system metaphors that are relevant to AIS. We will then give some illustrative real-world problems suitable for AIS use and show a step-by-step algorithm walkthrough. A comparison of AIS to other well-known algorithms and areas for future work will round this keynote off. It should be noted that as AIS is still a young and evolving field, there is not yet a fixed algorithm template and hence actual implementations might differ somewhat from the examples given here.

    Recommended childhood vaccines have typically been provided through routine immunization programs. Recently, implementation of strategies that use campaign-like features for providing all the recommended childhood immunizations have been utilized to increase vaccination coverage. Between January 2006 and January 2008, Assam, India, conducted Immunization Weeks (IWs), a periodic campaign-like approach for providing the recommended childhood vaccines generally administered through the routine Universal Immunization Program (UIP). Using data from a household vaccination coverage survey conducted in 5 districts of Assam in late-2007/early-2008 among children 12-28 months of age, a secondary analysis was conducted for a subset of children with vaccination cards to assess the impacts of implementing the IW-strategy. Sixty-five percent of the 3310 surveyed children received at least one vaccine dose through an IW. Without IWs, coverage would likely have been lower for all vaccines (e.g., 75% measles vaccine coverage including IWs doses and an estimated 61% without IWs). The proportion of children receiving at least one IW dose was significantly different depending on the child's residence; 72% in hard-to-reach char areas, 66% in rural areas and 53% in urban areas (p=0.01). Overall, 2085 (63%) of children were fully vaccinated; of these 60% received a combination of IW and UIP doses, 35% received doses only through the UIP, and 5% received doses only through IWs. A delay in administration later than the recommended ages was found for both UIP doses and for IW doses (e.g., for measles vaccine, UIP doses were 6.9 weeks delayed and IW doses 13.6 weeks delayed). Among this sample of vaccinated children, IWs appeared to increase vaccination coverage and improve access to services in hard-to-reach areas. However, the UIP appeared to be a better system for ensuring that children received all doses in the recommended vaccination series.

    Full Text Available Primary immune thrombocytopenia (ITP is one of the most common blood diseases as well as the commonest acquired bleeding disorder in childhood. Although the etiology of ITP is unclear, in the pathogenesis of the disease, both environmental and genetic factors including polymorphisms of TNF-a, IL-10, and IL-4 genes have been suggested to be involved. In this study, we investigated the rs2424913 single-nucleotide polymorphism (SNP (C46359T in DNA methyltransferase 3B (DNMT3B gene promoter and the VNTR polymorphism of IL-1 receptor antagonist (IL-1 Ra intron-2 in 32 children (17 boys with the diagnosis of ITP and 64 healthy individuals. No significant differences were found in the genotype distribution of DNMT3B polymorphism between the children with ITP and the control group, whereas the frequency of allele T appeared significantly increased in children with ITP (P = 0.03, OR = 2, 95% CI: 1.06–3.94. In case of IL-1 Ra polymorphism, children with ITP had a significantly higher frequency of genotype I/II, compared to control group (P = 0.043, OR = 2.60, 95% CI: 1.02–6.50. Moreover, genotype I/I as well as allele I was overrepresented in the control group, suggesting that allele I may have a decreased risk for development of ITP. Our findings suggest that rs2424913 DNMT3B SNP as well as IL-1 Ra VNTR polymorphism may contribute to the susceptibility to ITP.

    Full Text Available Introduction: Childhood morbidities like Acute Respiratory Infections (ARI, diarrhoea and malnutrition are very common.  As per NFHS-3, only 23% children aged 12-23 months were fully immunized in Uttar Pradesh. 9% under-five children had diarrhoea and 7.1% had ARI. Objective: To assess the impact of immunization status and childhood morbidities on nutritional status of under five children. Material & Methods: A cross sectional study was carried out among under five children in slums of Kanpur, using 30 cluster sampling technique. The sample size was calculated to be 375. From each slum, 13 subjects were studied thus giving a total sample size of 390. A pre-designed and pre-tested questionnaire was used to illicit the requisite information from the mothers of study subjects. Weight was recorded using standard technique for the same. Protein Energy Malnutrition (PEM was graded using IAP classification. Analysis of data was done using percentages and Chi square test. Results: The overall prevalence of PEM was found to be 54.87%. Malnutrition was found to be significantly higher (69.23% among unimmunized study subjects (p≤0.05. Among children who reported episodes of ARI and diarrhoea within last 1 month, 67.86% and 78.52% subjects respectively were malnourished. The association between PEM and these childhood morbidities was found to be statistically significant (p≤0.05. Conclusion: Prevention of diarrhoea and ARI and complete immunization of children under five years of age through National programmes and other health measures is the need of the hour for combating malnutrition in under five.

  4. Immune algorithm for discretization of decision systems in rough set theory

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    Rough set theory plays an important role in knowledge discovery, but cannot deal with continuous attributes, thus discretization is a problem which we cannot neglect. And discretization of decision systems in rough set theory has some particular characteristics. Consistency must be satisfied and cuts for discretization is expected to be as small as possible. Consistent and minimal discretization problem is NP-complete. In this paper, an immune algorithm for the problem is proposed. The correctness and effectiveness were shown in experiments. The discretization method presented in this paper can also be used as a data pretreating step for other symbolic knowledge discovery or machine learning methods other than rough set theory.

    An immunization strategy can take advantage of various tools, among which the pediatrician and family practitioner These figures, have been assigned the role of accompanying the child and his/her family throughout development. One of the objectives of this role is also to take a major part in the support of immunization coverage of infants, especially in light of the sospension of required immunizations in the Veneto Region. For this reason it is necessary to open dialogue on immunizations together with pediatricians and family physicians. In addition, training of these professional figures, together with healtcare operators who work in the immunization clinics, has allowed the formation and standardization of the network, as the persons who attend the immunization clinics are no longer passive users but persons who require information exchange in order to make an informed choice about immunizations for their children. Surveillance of vaccination coverage is a useful tool for evaluating the trend in vaccination refusals, and in particular it takes into consideration the motivation behind the refusal to adhere to the polio vaccine recommendations even if for now the coverage is maintained above 95%. Concluding, another strong point for the immunization program is "Genitori Più" which finds its continuity with the Regional Prevention Plan.

  6. Vitamin D in Early Childhood and the Effect on Immunity to Mycobacterium tuberculosis

    Anna Jane Battersby

    2012-01-01

    Full Text Available A potential role for vitamin D as a therapeutic immunomodulator in tuberculosis (TB has been recognised for over 150 years, but has only recently returned to the centre of the research arena due to the increasing awareness of the global vitamin D deficiency epidemic. As early as birth a child is often deficient in vitamin D, which may not only affect their bone metabolism but also modulate their immune function, contributing to the increased susceptibility to many infections seen early in life. Recent studies have begun to explain the mechanisms by which vitamin D affects immunity. Antimicrobial peptides are induced in conjunction with stimulation of innate pattern recognition receptors enhancing immunity to particular infections. In contrast the role of vitamin D within the adaptive immune response appears to be more regulatory in function, perhaps as a mechanism to reduce unwanted inflammation. In this paper we focus on the effect of vitamin D on immunity to TB. Where much of the attention has been paid by past reviews to the role of vitamin D in adult TB patients, this paper, where possible, focuses on research in paediatric populations.

    Background While the pentavalent rotavirus vaccine was highly efficacious against rotavirus diarrhea in clinical trials, the vaccine’s effectiveness under field conditions in the developing world is unclear. In October, 2006, Nicaragua became the first developing nation to implement universal infant immunization with the pentavalent rotavirus vaccine. To assess the impact of the immunization program, we examined the incidence of diarrhea episodes between 2003 and 2009 among children in the state of León, Nicaragua. Methods We extracted data on diarrhea episodes from health ministry records. We used scaled Poisson regression models to estimate diarrhea incidence rate ratios (IRR) for the period following the program’s implementation to the period before implementation. Results Following implementation of the immunization program, diarrhea episodes among infants were reduced (IRR 0.85, 95% confidence interval [CI] 0.71–1.02) during the rotavirus season, but appear to have increased during other months. Conclusions While the immunization program appears effective in reducing diarrhea episodes during the rotavirus season, a large burden of diarrhea persists during the remainder of the year.

    2014-08-01

    This study investigated whether a defendant's history of childhood sexual abuse (CSA) and/or personality disorder (PD) diagnosis affected juror decision making in a child sexual abuse trial. The PDs in the study were borderline PD and antisocial PD. Participants were 385 college students, 121 men and 264 women, who read a summary of a mock criminal trial and then made various juror decisions. Trial summaries were prepared by the principal investigator and were all uniform in content, length and detail. For the trial, both the defendant's gender and victim's gender were specified. The defendant was male, and the alleged victim was female. When the verdict was assessed, the results yielded that when the defendant's CSA history was presented, juror guilt ratings were higher than when there was no history of CSA. Similarly, when the defendant had a PD diagnosis, there were higher guilt ratings than when there was no PD diagnosis. CSA history and PD diagnosis were significant predictors of guilt ratings, suggesting that jurors perceive defendants more negatively if they have either been sexually abused as a child or have borderline or antisocial PD.

    Full Text Available Abstract Background Under the Dutch national immunization program (NIP, childhood vaccination is not mandatory, but its recommendation by childhood vaccine providers (CVP is important for maintaining high vaccination coverage. We therefore examined factors related to providers' intentions to recommend vaccinations to parents of young children. Methods We conducted four focus group discussions with nurses and physicians who provide vaccines to children 0-4 years old in diverse regions of the Netherlands. Three groups represented CVPs at child welfare centers (CWCs serving the general population, with the fourth representing anthroposophical CWCs. Elements of the Theory of Planned Behaviour (TPB were used to design the groups; thematic analysis was used to structure and analyze the dataset. Results Four main themes emerged, including 1 perceived responsibility: to promote vaccines and discuss pros and cons with parents (although this was usually not done if parents readily accepted the vaccination; 2 attitudes toward the NIP: mainly positive, but doubts as to NIP plans to vaccinate against diseases with a low perceived burden; 3 organizational factors: limited time and information can hamper discussions with parents; 4 relationship with parents: crucial and based mainly on communication to establish trust. Compared to CVPs at standard CWCs, the anthroposophical CWCs spent more time communicating and were more willing to adapt the NIP to individual cases. Conclusions Our qualitative assessment provides an overview of beliefs associated with providers' intention to recommend vaccinations. They were motivated to support the NIP, but their intentions to recommend vaccinations were affected by the perceived relevance of the vaccines, practical issues like limited time and by certain types of resistant parents. These results will inform future studies to test the magnitude and relative impact of these factors.

  10. The Role of Genetic and Immune Factors for the Pathogenesis of Primary Sclerosing Cholangitis in Childhood

    2016-01-01

    Primary sclerosing cholangitis (PSC) is a rare cholestatic liver disease characterized by chronic inflammation of the biliary tree resulting in liver fibrosis. PSC is more common in male less than 40 years of age. The diagnosis of PSC is based on clinical, laboratory, image, and histological findings. A biochemical profile of mild to severe chronic cholestasis can be observed. Endoscopic retrograde cholangiography is the golden standard method for diagnosis, but magnetic resonance cholangiography is currently also considered a first-line method of investigation. Differences in clinical and laboratory findings were observed in young patients, including higher incidence of overlap syndromes, mostly with autoimmune hepatitis, higher serum levels of aminotransferases and gamma-glutamyl transferase, and lower incidence of serious complications as cholangiocarcinoma. In spite of the detection of several HLA variants as associated factors in large multicenter cohorts of adult patients, the exact role and pathways of these susceptibility genes remain to be determined in pediatric population. In addition, the literature supports a role for an altered immune response to pathogens in the pathogenesis of PSC. This phenomenon contributes to abnormal immune system activation and perpetuation of the inflammatory process. In this article, we review the role of immune and genetic factors in the pathogenesis of PSC in pediatric patients. PMID:27882046

    We examined the impact of expert witness orientation (researcher or clinical practitioner) and type of testimony (testimony for the prosecution, defense, both prosecution and defense, or no testimony) on mock jurors' decisions in a sexual abuse trial. Participants acted as mock jurors on a sexual abuse criminal trial based on recovered memory that included expert witness testimony. Results showed that expert witness testimony provided by a researcher did not impact mock jurors' guilt ratings any differently than the expert witness testimony provided by a clinical practitioner. However, type of testimony had a significant effect on jurors' guilt ratings such that jurors who read only defense or only prosecution testimony made decisions favoring the relevant side.

    We evaluated the effectiveness of the heptavalent pneumococcal conjugate vaccine (PCV7) on invasive pneumococcal disease (IPD) 1 year after PCV7's introduction in the childhood immunization programme through a nationwide cohort study based on laboratory surveillance data. There was a decline......, the incidence decreased from 54 to 23 cases per 100,000 (IRR 0.43; 95% CI [0.29-0.62]) and for vaccine-serotypes from 36.7 to 7.7 (IRR 0.20; 95% CI [0.09-0.38]). The incidence of IPD declined approximately 10% (IRR 0.90; 95% CI [0.84-0.97]) in patients aged >or=2 years. The case fatality was 17% in both periods...... in the overall incidence of IPD from 19.4 to 17.1 cases per 100,000 population (incidence rate ratios (IRR) 0.87; 95% confidence interval (CI) [0.81-0.96]), and of meningitis from 1.56 to 1.16 (IRR 0.74; 95% CI [0.57-0.97]) comparing pre-PCV7 (years 2000-2007) and PCV7 (year 2008) periods.

    The developing immune system and central nervous system in the fetus and child are extremely sensitive to both exogenous and endogenous signals. Early immune system programming, leading to changes that can persist over the life course, has been suggested, and other evidence suggests that immune dysregulation in the early developing brain may play a role in neurodevelopmental disorders such as autism spectrum disorder and schizophrenia. The timing of immune dysregulation with respect to gestational age and neurologic development of the fetus may shape the elicited response. This creates a possible sensitive window of programming or vulnerability. This review will explore the effects of maternal prenatal and infant nutritional status (from conception until early childhood) as well as maternal prenatal stress and anxiety on early programming of immune function, and how this might influence neurodevelopment. We will describe fetal immune system development and maternal-fetal immune interactions to provide a better context for understanding the influence of nutrition and stress on the immune system. Finally, we will discuss the implications for prevention of neurodevelopmental disorders, with a focus on nutrition. Although certain micronutrient supplements have shown to both reduce the risk of neurodevelopmental disorders and enhance fetal immune development, we do not know whether their impact on immune development contributes to the preventive effect on neurodevelopmental disorders. Future studies are needed to elucidate this relationship, which may contribute to a better understanding of preventative mechanisms. Integrating studies of neurodevelopmental disorders and prenatal exposures with the simultaneous evaluation of neural and immune systems will shed light on mechanisms that underlie individual vulnerability or resilience to neurodevelopmental disorders and ultimately contribute to the development of primary preventions and early interventions.

    The current 'Darwinian' synthesis of the hygiene (or 'Old Friends') hypothesis suggests that the increase in chronic inflammatory disorders that started in Europe in the mid-19th century and progressed until the late 20th century is at least partly attributable to immunodysregulation resulting from lack of exposure to microorganisms that were tasked by co-evolutionary processes with establishing the 'normal' background levels of immunoregulation, a role that they perform in concert with the normal microbiota. This is an example of 'evolved dependence'. The relevant organisms co-evolved with mammals, already accompanied early hominids in the Paleolithic era and are associated with animals, mud and faeces. These organisms often establish stable carrier states, or are encountered continuously in primitive environments as 'pseudocommensals' from mud and water. These organisms were not lost during the first epidemiological transition, which might even have resulted in increased exposure to them. However, the crucial organisms are lost progressively as populations undergo the second epidemiological transition (modern urban environment). Recently evolved sporadic 'childhood infections' are not likely to have evolved immunoregulatory roles, and epidemiology supports this contention. The consequences of the loss of the Old Friends and distortion of the microbiota are aggravated by other modern environmental changes that also lead to enhanced inflammatory responses (obesity, vitamin D deficiency, pollution (dioxins), etc.). The range of chronic inflammatory disorders affected may be larger than had been assumed (allergies, autoimmunity, inflammatory bowel disease, but also coeliac disease, food allergy, vascular disease, some cancers, and depression/anxiety when accompanied by raised inflammatory cytokines).

    Full Text Available Abstract Background Symptomatic hypogammaglobulinemia in infancy and childhood (SHIC, may be an early manifestation of a primary immunodeficiency or a maturational delay in the normal production of immunoglobulins (Ig. We aimed to evaluate the natural course of SHIC and correlate in vitro lymphoproliferative and secretory responses with recovery of immunoglobulin values and clinical resolution. Methods Children, older than 1 year of age, referred to our specialist clinic because of recurrent infections and serum immunoglobulin (Ig levels 2 SD below the mean for age, were followed for a period of 8 years. Patient with any known familial, clinical or laboratory evidence of cellular immunodeficiency or other immunodeficiency syndromes were excluded from this cohort. Evaluation at 6- to 12-months intervals continued up to 1 year after resolution of symptoms. In a subgroup of patients, in vitro lymphocyte proliferation and Ig secretion in response to mitogens was performed. Results 32 children, 24 (75% males, 8 (25% females, mean age 3.4 years fulfilled the inclusion criteria. Clinical presentation: ENT infections 69%, respiratory 81%, diarrhea 12.5%. During follow-up, 17 (53% normalized serum Ig levels and were diagnosed as transient hypogammaglobulinemia of infancy (THGI. THGI patients did not differ clinically or demographically from non-transient patients, both having a benign clinical outcome. In vitro Ig secretory responses, were lower in hypogammaglobulinemic, compared to normal children and did not normalize concomitantly with serum Ig's in THGI patients. Conclusions The majority of children with SHIC in the first decade of life have THGI. Resolution of symptoms as well as normalization of Ig values may be delayed, but overall the clinical outcome is good and the clinical course benign.

  19. How is childhood development of immunity to Plasmodium falciparum enhanced by certain antimalarial interventions?

    2007-12-01

    Full Text Available Abstract The development of acquired protective immunity to Plasmodium falciparum infection in young African children is considered in the context of three current strategies for malaria prevention: insecticide-impregnated bed nets or curtains, anti-sporozoite vaccines and intermittent preventive therapy. Evidence is presented that each of these measures may permit attenuated P. falciparum blood-stage infections, which do not cause clinical malaria but can act as an effective blood-stage "vaccine". It is proposed that the extended serum half-life, and rarely considered liver-stage prophylaxis provided by the anti-folate combination sulphadoxine-pyrimethamine frequently lead to such attenuated infections in high transmission areas, and thus contribute to the sustained protection from malaria observed among children receiving the combination as intermittent preventative therapy or for parasite clearance in vaccine trials.

    Race/ethnic disparities in utilization of children's mental health care have been well documented and are particularly concerning given the long-term risks of untreated mental health problems (Institute of Medicine, 2003; Kessler et al. Am J Psychiatry 152:10026-1032, 1995). Research investigating the higher rates of unmet need among race/ethnic minority youths has focused primarily on policy, fiscal, and individual child or family factors that can influence service access and use. Alternatively, this study examines provider behavior as a potential influence on race/ethnic disparities in mental health care. The goal of the study was to examine whether patient (family) race/ethnicity influences physician diagnostic and treatment decision-making for childhood disruptive behavior problems. The study utilized an internet-based video vignette with corresponding survey of 371 randomly selected physicians from across the USA representing specialties likely to treat these patients (pediatricians, family physicians, general and child psychiatrists). Participants viewed a video vignette in which only race/ethnicity of the mother randomly varied (non-Hispanic White, Hispanic, and African American) and then responded to questions about diagnosis and recommended treatments. Physicians assigned diagnoses such as oppositional defiant disorder (48 %) and attention deficit disorder (63 %) to the child, but there were no differences in diagnosis based on race/ethnicity. The majority of respondents recommended psychosocial treatment (98 %) and/or psychoactive medication treatment (60 %), but there were no significant differences based on race/ethnicity. Thus, in this study using mock patient stimuli and controlling for other factors, such as insurance coverage, we did not find major differences in physician diagnostic or treatment decision-making based on patient race/ethnicity.

    Full Text Available Abstract. This section of our review article deals with prevalence, genetic factors, and some immune mechanisms of chronic urticaria in children. In any form of chronic urticaria, the main pathogenetic role is ascribed to mast cells and basophiles. Increased production of cyto- and chemokines, e.g., CCL2, CХCL8, IL-1, IL-4, IL-6, IL-10, IL-13, IL-17, is observed during chronic inflammatory reactions typical to this disease. Activation of mast cells and basophiles proceeds via specific receptors on the target cell membranes. Autoimmune urticaria is of special importance. In this disorder, autoantibodies are directed against IgE or FCεRIα, thus causing histamine release, due to cross-linking of α-chains of high-affinity IgE receptor, or binding of IgE fixed on the mast cells. Degranulation of basophils is followed by occurrence of activation molecules (СD203с, CD63. Some workers presumet that association between СD203с expression and positive autologous serum skin test may be a sign of autoimmune process. Increased expression of CD40L ligand on the surface of activated T cells suggests enhanced signaling for B cell activation and production of autoantibodies.

    Full Text Available Multi-stakeholder partnerships (MSPs have become a widespread means for deploying policies in a whole of society strategy to address the complex problem of childhood obesity. However, decision-making in MSPs is fraught with challenges, as decision-makers are faced with complexity, and have to reconcile disparate conceptualizations of knowledge across multiple sectors with diverse sets of indicators and data. These challenges can be addressed by supporting MSPs with innovative tools for obtaining, organizing and using data to inform decision-making. The purpose of this paper is to describe and analyze the development of a knowledge-based infrastructure to support MSP decision-making processes. The paper emerged from a study to define specifications for a knowledge-based infrastructure to provide decision support for community-level MSPs in the Canadian province of Quebec.

  4. When, and how, should we introduce a combination measles-mumps-rubella (MMR) vaccine into the national childhood expanded immunization programme in South Africa?

    2012-09-07

    This article briefly reviews the history and epidemiology of measles, mumps and rubella disease and the case for introducing combination measles-mumps-rubella (MMR) vaccine into the national childhood immunization schedule in South Africa. Despite adopting the World Health Organization's Measles Elimination strategy in 1996 and achieving a significant decrease the incidence of measles, added effort is needed in South and southern Africa to reach the goal to eliminate endogenous spread measles. Mumps is still common disease of childhood and while there are few sequelae, even the rare complications are important in large populations. Congenital rubella syndrome is seldom reported, but it is estimated that of the million or so children born every year in South Africa over 600 infants are affected to some degree by rubella infection. The naturally acquired immunity to rubella in women of childbearing age in South Africa has been estimated at over 90%, so that introducing a rubella containing vaccine in childhood may paradoxically increase the proportion of girls reaching puberty still susceptible to rubella. The elimination of endogenous measles and rubella is being achieved in many countries in South America, and despite the recent measles epidemic, must still be seriously considered for South and southern Africa. Current constraints and potential steps needed to reach the goal in South Africa are discussed.

    Rapid assessment of platelet production would distinguish between thrombocytopenia due to decreased platelet production or increased peripheral platelet destruction. We evaluated the value of immature platelet fraction (IPF) in differentiating immune thrombocytopenia (ITP) from thrombocytopenia secondary to bone marrow failure and its potential use as a prognostic marker. Forty-one young patients with ITP were compared with 14 patients with hematological malignancies under chemotherapy, representing a control group with thrombocytopenia due to bone marrow suppression and 30 age- and sex-matched healthy controls. Patients were studied stressing on bleeding manifestations, organomegaly/lymphadenopathy and therapy. Complete blood count including IPF was performed using Sysmex XE-2100. ITP patients were classified into two subgroups: acute ITP with spontaneous resolution within 3 months from diagnosis and chronic ITP that lasted ≥ 1 year from diagnosis. Median IPF was 11.8% in patients with ITP, 7% in those with hematological malignancy and 3% in the control group (p < 0.001). ITP patients had significantly higher mean platelet volume (MPV), platelet distribution width (PDW), platelet large cell ratio (P-LCR) and IPF compared with patients with malignancy or healthy controls, while plateletcrit (PCT) was significantly lower in ITP patients than other groups (p < 0.001). IPF was increased in patients with chronic ITP compared with acute ITP group (p < 0.001). Patients with active ITP had the highest IPF followed by those in partial remission, while ITP patients in remission had the lowest IPF. IPF was positively correlated to the number of lines of treatment used, MPV, PDW and P-LCR, while negatively correlated to platelet count and PCT among ITP patients (p < 0.001). Multiple regression analysis showed that platelet count and P-LCR were independently related to IPF. ROC curve analysis revealed that the cut-off value of IPF at 9.4% could be diagnostic for ITP patients

    Full Text Available Background: Immunization coverage rates in Nigeria have remained very poor, in spite of numerous programs and strategies, specifically designed to improve coverage. This study was to assess the possible effects of greater community participation on immunization coverage, by comparing the immunization coverage in a rural community with a functional community health committee, with an urban community, with no distinct community structure. Materials and Methods: The study was carried out in Ondewari, a rural, riverine community, in Bayelsa State; and Yenagoa, the capital of Bayelsa State, south-south Nigeria; using a cross-sectional, comparative study design. The data were collected using a structured interviewer-administered questionnaire, administered on female head of households in both communities, with under-five children; and used to collect information on the socio-demographic characteristics of the respondents, the immunization status of children in the household below the age of 2 years, and reasons for none and incomplete immunization. Results: A total of 288 respondents were studied in the rural community, while 270 respondents were studied in the urban center. The respondents in the urban center were significantly younger (P<0.01, better educated (P<0.001, and had fewer number of children (P<0.01. The immunization status of children in the rural community was significantly better than those in the urban community (P<0.000. Only 11.46% of the children in the rural community were not immunized, compared to 47.04% in the urban community. However, the dropout rate in the rural community was much higher; with a DPT dropout rate of 77.34%, compared to 12.39% in the urban community. Most of the reasons given in the urban community for the incomplete immunization were linked lack of motivation, and include relocation (11.34% and the adverse rumor about childhood immunization (17.23%, while the reasons in the rural community were mostly health

    Studies have shown clearly that childhood mistreatment, abuse and neglect are associated with severe inflammatory disease in adulthood (e. g. cancer, heart disease, autoimmune disorder) and shortened life span. This review deals with the psychoneuroimmunological pathways of this connection. It shows that chronic stressors interfere very early in life with those protective mechanisms of the biological stress system that normally down-regulate potentially harmful inflammation. In the long term, serious inflammatory diseases, such as allergic asthma, can result. In this review, the pathogenetic connections between allergic asthma and early stress and stress system dysfunction are discussed. As our understanding of the dysfunctional psychophysiological mechanisms of inflammatory disease increases, psychodiagnostic and psychotherapeutic intervention in the treatment of physical disease will become more specific.

    The irremediable ageing of the world population, the aged-related increasing in the prevalence of infectious diseases the fear of any influenza pandemic rife have recently led the European Union Geriatric Medicine Society (EUGMS) et the International Association of Geriatric and Gerontology European Regions (IAGG-ER) of establishing vaccine recommendations dedicated to individuals aged of 60 years or above and promoting a life-course vaccination programme. This approach is mainly motivated by the herd immunity-associated effect on the epidemiology of infectious diseases observed within the adult and old adult population. This review (1) after a presentation of the concept and its demonstrated beneficial effects; (2) will detail that herd immunity acts with adverse effects on the epidemiology of the infectious diseases in the adult and aged individual population; (3) in order to demonstrate that maintaining a vaccine pressure in every age groups is imperative.

    This paper presents data from two studies that evaluated 5-y and 10-y persistence of antibodies against hepatitis B (HBV) surface antigen (anti-HBs) and immune response to an HBV vaccine challenge in children and adolescents who had received three doses of a HBV vaccine in infancy as part of routine clinical practice [NCT00519649/NCT00984139]. Anti-HBs antibody concentrations ≥ 10 mIU/ml persisted in 83.3% (95% confidence interval [CI]: 78.5–87.5) and 78.3% (95% CI: 73.1–83.0) of subjects aged 7–8 y and 12–13 y, respectively 5–10 y after infant vaccination. One month postchallenge dose, 98.2% (95% CI: 95.9–99.4) and 93.7% (95% CI: 90.2–96.2) of subjects in the two age groups, respectively had anti-HBs antibody concentrations ≥ 100 mIU/ml. Overall, 99.6% (95% CI: 98–100) and 97.2% (95% CI: 94.5–98.8) of subjects aged 7–8 y and 12–13 y mounted an anamnestic response to the HBV challenge dose, which was well-tolerated. Healthy children aged 7–8 y and adolescents aged 12–13 y received three doses of a monovalent pediatric HBV vaccine (10 μg of HBsAg) before 18 mo of age. Serum samples collected before and one month post-HBV vaccine challenge dose were tested for anti-HBs antibody concentrations. Safety assessments were made for the HBV vaccine challenge dose. A three-dose childhood HBV immunization regimen induced persistence of antibodies against HBV infection for 10 y, up to adolescence. This vaccination regimen also conferred long-term immune memory against HBV as evidenced by the strong anamnestic response to the HBV vaccine challenge, despite waning anti-HBs antibody levels.

    Natalie Carvalho

    Full Text Available BACKGROUND: In 2005, India established a conditional cash transfer program called Janani Suraksha Yojana (JSY, to increase institutional delivery and encourage the use of reproductive and child health-related services. OBJECTIVE: To assess the effect of maternal receipt of financial assistance from JSY on childhood immunizations, post-partum care, breastfeeding practices, and care-seeking behaviors. METHODS: We use data from the latest district-level household survey (2007-2008 to conduct a propensity score matching analysis with logistic regression. We conduct the analyses at the national level as well as separately across groups of states classified as high-focus and non-high-focus. We carry out several sensitivity analyses including a subgroup analysis stratified by possession of an immunization card. RESULTS: Receipt of financial assistance from JSY led to an increase in immunization rates ranging from 3.1 (95%CI 2.2-4.0 percentage points for one dose of polio vaccine to 9.1 (95%CI 7.5-10.7 percentage points in the proportion of fully vaccinated children. Our findings also indicate JSY led to increased post-partum check-up rates and healthy early breastfeeding practices around the time of childbirth. No effect of JSY was found on exclusive breastfeeding practices and care-seeking behaviors. Effect sizes were consistently larger in states identified as being a key focus for the program. In an analysis stratified by possession of an immunization card, there was little to no effect of JSY among those with vaccination cards, while the effect size was much larger than the base case results for those missing vaccination cards, across nearly all immunization outcomes. CONCLUSIONS: Early results suggest the JSY program led to a significant increase in childhood immunization rates and some healthy reproductive health behaviors, but the structuring of financial incentives to pregnant women and health workers warrants further review.

    Full Text Available Background: To empower patients to optimize lifestyle factors and compliance in intervention strategies, predictive personalised simulation models such as developed in the framework of the Virtual Physiological Human initiative (http://www.vph-institute.org/ are a potential important asset. Aim:The FP7 EU project MISSION-T2D aims to develop and validate a computer model incorporating genetic, metabolic, and nutritional data for the simulation and prediction of the onset and progression of T2D. The model should include immunological/inflammatory processes contributing to insulin resistance and beta cell function loss, functionally interacting with energy intake/expenditure-associated metabolic regulatory mechanisms. Methods: The overall architecture of the model interconnects and integrates an already established immune system simulator with newly developed and/or adapted discrete and continuous mathematical simulation models for relevant processes as detailed below. The model is programmed in ANSI/C. Results: Model sections are as follows: 1 GUT MICROBIOTA: predicts how different dietary components affect the relative abundance of important gut bacteria, thus influencing butyrate production, and thereby modulating TNF, IL-6 and IL-1β; 2 PANCREATIC BETA CELL employs mTOR signaling as a central mechanism and predicts the beta cell survival and –functionality as a function of concentration of macrophages, acivated macrophages, and beta cell antigenic proteins; 3 WHOLE BODY METABOLISM describes seven tissue compartments: brain, heart, liver, gastrointestinal tract, skeletal muscle, and adipose tissue, by dynamic mass balances for major cellular metabolic reactions involving glucose, lactate, pyruvate, alanine, free fatty acids, triglycerides, glycerol and ATP as driven by macronutrient meal intake and hormonal control by insulin, glucagon and epinphrine; 4 PHYSICAL ACTIVITY predicts epinephrine concentration and IL-6 as a function of exercise

    Full Text Available Background: at present, there are considered the efficient mechanisms existed by which diets high in n-3 LC PUFAs during pregnancy and early childhood may modulate the development of innative immune disorders and promote the adequate formation of immune system both on general and local levels. Early availability of n-3 LC PUFA could contribute to the normal growth and development, decrease risk factors of diseases or pathological disorders in infants. Goals: to assess the relationship between n-3 LC PUFAs intakes during pregnancy and postnatally and development, morbidity and immunity of infants in first year of life. A retrospective study was conducted using interview method of 300 women, whose children reached the age of one year. Elaborated questionnaires were filled in by pediatricians throughout their daily working hours while attending the patients. Was conducted assessment of frequency of common diseases and disorders like respiratory diseases, functional intestinal disorders and atopic diseases. Were investigated immunity of infants assessing the content of IgA, IgG and IgM by immunological methods and detected DHA, EPA (n-3 LC PUFAs and AA (n-6 LC PUFAs by gas chromatographic analysis in blood serum of children. The outcomes of the study were analysed and processed using statistical methods. Retrospective clinical findings indicate on higher incidence of acute respiratory tract and atopic diseases as well as functional disorders of the gastrointestinal tract in infants whose mothers did not use seafood in their diets during the pregnancy and in the lactating period. The research of immunity of children showed no difference in concentration of IgG and IgM in blood serum (p >> 0,05 but significant difference for IgA concentrations in plasma. In infants of n-3 LC PUFAs group IgA concentration was higher compared to opposite group. The fatty acid composition of the blood serum showed changes in the content of the main representatives of n-3

    Full Text Available Abstract Background Population-based registries have been promoted as an effective method to improve childhood immunization rates, yet rates of registry participation in the private sector are low. We sought to describe, through a national overview, the perspectives of childhood immunization providers in private practice regarding factors associated with participation or non-participation in immunization registries. Methods Two mailed surveys, one for 264 private practices identified as registry non-participants and the other for 971 identified as registry participants, from 15 of the 31 states with population-based statewide immunization registries. Frequency distributions were calculated separately for non-participants and participants regarding the physician-reported factors that influenced decisions related to registry participation. Pearson chi-square tests of independence were used to assess associations among categorical variables. Results Overall response rate was 62% (N = 756. Among non-participants, easy access to records of vaccines provided at other sites (N = 101, 68% and printable immunization records (N = 82, 55% were most often cited as "very important" potential benefits of a registry, while the most commonly cited barriers to participation were too much cost/staff time (N = 36, 38% and that the practice has its own system for recording and monitoring immunizations (N = 35, 37%. Among registry participants, most reported using the registry to input data on vaccines administered (N = 326, 87% and to review immunization records of individual patients (N = 302, 81%. A minority reported using it to assess their practice's immunization coverage (N = 110, 29% or generate reminder/recall notices (N = 54, 14%. Few participants reported experiencing "significant" problems with the registry; the most often cited was cost/staff time to use the registry (N = 71, 20%.

    Since the introduction of HPV vaccination programs in Canada in 2007, coverage has been below public health goals in many provinces and territories. This analysis investigated the determinants of HPV non-vaccination and vaccine refusal. Data from the Childhood National Immunization Coverage Survey (CNICS) 2013 were used to estimate the prevalence of HPV non-vaccination and parental vaccine refusal in girls aged 12-14 years, for Canada and the provinces and territories. Multivariate logistic regression was used to examine factors associated with non-vaccination and vaccine refusal, after adjusting for potential confounders. An estimated 27.7% of 12-14 y old girls had not been vaccinated against HPV, and 14.4% of parents reported refusing the vaccine. The magnitude of non-vaccination and vaccine refusal varied by province or territory and also by responding parent's country of birth. In addition, higher education was associated with a higher risk of refusal of the HPV vaccine. Rates of HPV non-vaccination and of refusal of the HPV vaccine differ and are influenced by different variables. These findings warrant further investigation.

  6. Effects of Treatment on IgE Responses against Parasite Allergen-Like Proteins and Immunity to Reinfection in Childhood Schistosome and Hookworm Coinfections

    Naturally occurring human immunity to both schistosomiasis and hookworm infection has been associated with IgE responses against parasite allergen-like proteins. Since the two helminths frequently coinfect the same individuals, there is growing advocacy for their concurrent treatment. However, both helminths are known to exert strong immunomodulatory effects; therefore, coinfected individuals could have immune responses different from those characteristically seen in monoinfected individuals. In this study, we measured changes in IgE, IgG1, and IgG4 responses to schistosome and hookworm antigens, including the allergen-like proteins Schistosoma mansoni tegumental-allergen-like 1 protein (SmTAL1), SmTAL2, and Necator americanus Ancylostoma-secreted protein-2 (Na-ASP-2), following concurrent treatment of schoolchildren coinfected with Schistosoma mansoni and hookworm. Antibody responses to schistosome egg (soluble egg antigen and SmTAL2) or somatic adult hookworm (AHW) antigens either decreased after treatment or were unchanged, whereas those to schistosome worm antigens (soluble worm antigen and SmTAL1) increased. The observed different effects of treatment likely reflect the different modes of drug action and sites of infection for these two helminths. Importantly, there was no evidence that the simultaneous treatment of coinfected children with praziquantel and albendazole affected schistosome- and hookworm-specific humoral responses differently from those characteristic of populations in which only one organism is endemic; schistosome- and hookworm-specific responses were not associated, and there was no evidence for cross-regulation. Posttreatment increases in the levels of IgE to schistosome worm antigens were associated with lower Schistosoma mansoni reinfection intensity, while no associations between humoral responses to AHW antigen and protection from hookworm reinfection were observed in this sample of school-aged children.

    In August 2012, the Brazilian Ministry of Health introduced inactivated polio vaccine (IPV) as part of sequential polio vaccination schedule for all infants beginning their primary vaccination series. The revised childhood immunization schedule included 2 doses of IPV at 2 and 4 months of age followed by 2 doses of oral polio vaccine (OPV) at 6 and 15 months of age. One annual national polio immunization day was maintained to provide OPV to all children aged 6 to 59 months. The decision to introduce IPV was based on preventing rare cases of vaccine-associated paralytic polio, financially sustaining IPV introduction, ensuring equitable access to IPV, and preparing for future OPV cessation following global eradication. Introducing IPV during a national multivaccination campaign led to rapid uptake, despite challenges with local vaccine supply due to high wastage rates. Continuous monitoring is required to achieve high coverage with the sequential polio vaccine schedule.

    Childhood obesity is an issue of serious medical and social concern. In developing countries including India, it is a phenomenon seen in higher socioeconomic strata due to the adoption of a western lifestyle. Consumption of high calorie food, lack of physical activity and increased screen time are major risk factors for childhood obesity apart from other genetic, prenatal factors and socio-cultural practices. Obese children and adolescents are at increased risk of medical and psychological complications. Insulin resistance is commonly present especially in those with central obesity and manifests as dyslipidemia, type 2 diabetes mellitus, impaired glucose tolerance, hypertension, polycystic ovarian syndrome and metabolic syndrome. Obese children and adolescents often present to general physicians for management. The latter play a key role in prevention and treatment of obesity as it involves lifestyle modification of the entire family. This article aims at discussing the approach to diagnosis and work-up, treatment and preventive strategies for childhood obesity from a general physician's perspective.

  10. Asthma in childhood: a complex, heterogeneous disease

    Full Text Available Asthma in childhood is a heterogeneous disease with different phenotypes and variable clinical manifestations, which depend on the age, gender, genetic background, and environmental influences of the patients. Several longitudinal studies have been conducted to classify the phenotypes of childhood asthma, on the basis of the symptoms, triggers of wheezing illness, or pathophysiological features of the disease. These studies have provided us with important information about the different wheezing phenotypes in young children and about potential mechanisms and risk factors for the development of chronic asthma. The goal of these studies was to provide a better insight into the causes and natural course of childhood asthma. It is well-known that complicated interactions between genes and environmental factors contribute to the development of asthma. Because childhood is a period of rapid growth in both the lungs and the immune system, developmental factors should be considered in the pathogenesis of childhood asthma. The pulmonary system continues to grow and develop until linear growth is completed. Longitudinal studies have reported significant age-related immune development during postnatal early life. These observations suggest that the phenotypes of childhood asthma vary among children and also in an individual child over time. Improved classification of heterogeneous conditions of the disease will help determine novel strategies for primary and secondary prevention and for the development of individualized treatment for childhood asthma.

    Approximately 10% of children are obese. Twin and adoption studies demonstrate a large genetic component to obesity, especially in adults. However, the increasing prevalence of obesity over the last 20 years can only be explained by environmental factors. In most obese individuals, no measurable differences in metabolism can be detected. Few children engage in regular physical activity. Obese children and adults uniformly underreport the amount of food they eat. Obesity is particularly related to increased consumption of high-fat foods. BMI is a quick and easy way to screen for childhood obesity. Treating childhood obesity relies on positive family support and lifestyle changes involving the whole family. Food preferences are influenced early by parental eating habits, and when developed in childhood, they tend to remain fairly constant into adulthood. Children learn to be active or inactive from their parents. In addition, physical activity (or more commonly, physical inactivity) habits that are established in childhood tend to persist into adulthood. Weight loss is usually followed by changes in appetite and metabolism, predisposing individuals to regain their weight. However, when the right family dynamics exist--a motivated child with supportive parents--long-term success is possible.

    Acute pancreatitis is a rare finding in childhood but probably more common than is generally realized. This condition should be considered in the evaluation of children with vomiting and abdominal pain, because it can cause significant morbidity and mortality. Clinical suspicion is required to make the diagnosis, especially when the serum amylase concentration is normal. Recurrent pancreatitis may be familial as a result of inherited biochemical or anatomic abnormalities. Patients with hereditary pancreatitis are at high risk for pancreatic cancer.

    In recent years, parents have become more disparaging towards childhood vaccination. One group that is critical about the National Immunization Program (NIP) and participates less comprises parents with an anthroposophical worldview. Despite the fact that various studies have identified anthroposophists as critical parents with lower vaccination coverage, no research has been done to explore the beliefs underlying their childhood vaccination decision-making. We conducted a qualitative study using three focus groups (n = 16) of parents who visit an anthroposophical child welfare center. Our findings show that participants did not refuse all vaccinations within the Dutch NIP, but mostly refused the Mumps, Measles, and Rubella (MMR) vaccination. Vaccination decisions are influenced by participants' lifestyle, perception of health, beliefs about childhood diseases, perceptions about the risks of diseases, perceptions about vaccine effectiveness and vaccine components, and trust in institutions. Parents indicated that they felt a need for more information. Sufficient references should be provided to sources containing more information about childhood vaccination, especially about the effectiveness of vaccines and vaccine components and the risks, such as possible side effects and benefits of vaccination. This may satisfy parents' information needs and enable them to make a sufficiently informed choice whether or not to vaccinate their child.

  1. Pertussis immunization in the global pertussis initiative North American region: recommended strategies and implementation considerations.

    In North America, children currently receive 5 doses of a combined diphtheria-tetanus-acellular pertussis vaccine between the ages of 2 months and 6 years. Although this schedule has reduced the incidence of childhood pertussis, it has not led to the development of herd immunity in the total population, largely because pertussis immunity wanes with time. The time course over which immunity wanes is uncertain; however, high pertussis antibody titers in adolescents and adults indicate unrecognized infection in these groups. There is evidence that this group serves as a source of infection for young infants who are not fully immunized. Therefore, of the potential strategies reviewed by the North American Global Pertussis Initiative group, universal adolescent immunization would in theory reduce the risk of pertussis in this age group and may reduce transmission to young infants. However, because immunity probably wanes at the same rate in adolescents and children, the burden of disease will likely shift to older age groups, including young adults (parents of vulnerable infants). Therefore the ideal would be immunization of adolescents and adults, particularly those who are in contact with young infants. Adolescent immunization is already recommended in Austria, France, Germany and Canada, and participants in the Global Pertussis Initiative recommend that this strategy be implemented across North America with a view to eventually extending immunization to include adults. The final decision to implement such a strategy will depend on pertussis surveillance studies and analysis of the effectiveness and tolerability of adolescent and adult pertussis immunization as well as program considerations related to feasibility and economics.

    In industrial countries, 1 child out of 500 develops a cancer before the age of 15 years, and before the age of 6 years for almost half of them. In France, incidence rates were stable over the 15 last years with around 1500 cases each year. A very small fraction of cases is attributable to known risk factors, including heritable cancers or cancers in children with heritable predisposing diseases, cancers induced by high doses of ionizing radiation of medical or accidental origin, by chemotherapeutic or immunosuppressive drugs. Responsibility of Epstein Barr virus in a fraction of Hodgkin's and Burkitt's lymphomas is also established, even though little is still known on the cofactors involved in industrial countries. Other virus could cause leukaemia, as suggested by localized increases in incidence in various conditions of population mixing. Conversely, there is some evidence that early common infections could be protective toward leukaemia risk, probably through their contribution to the maturation of the immune system. Several agents are suspected to induce chemical cancers, particularly pesticides, which are consistently reported in childhood leukaemia and brain tumours. It is more and more likely that genetic factors may modulate risk induced of environmental factors.

  6. Etiology of common childhood acute lymphoblastic leukemia: the adrenal hypothesis

    2008-01-01

    The pattern of infections in the first years of life modulates our immune system, and a low incidence of infections has been linked to an increased risk of common childhood acute lymphoblastic leukemia (ALL). We here present a new interpretation of these observations--the adrenal hypothesis......--that proposes that the risk of childhood ALL is reduced when early childhood infections induce qualitative and quantitative changes in the hypothalamus-pituitary-adrenal axis that increase plasma cortisol levels. This may directly eliminate leukemic cells as well as preleukemic cells for the ALL subsets...

    2008-08-01

    Several new vaccines for children and young adults have been introduced recently and now appear on the Advisory Committee on Immunization Practices' recommended childhood and adolescent immunization schedule (meningococcal, rotavirus, human papillomavirus). As new vaccines are introduced, states face complex decisions regarding which vaccines to fund and which vaccines to require for school or child care entry. This complexity is evidenced by the current debate surrounding the human papillomavirus vaccine. We present a critique to the approach and criteria for evaluating vaccines for inclusion in mandatory school immunization programs that have been adopted by the Washington State Board of Health by illustrating how these criteria might be applied to the human papillomavirus vaccine. We conclude that these 9 criteria can help ensure a deliberate and informed approach to important public policy decisions, but we argue that several clarifications of the review process are needed along with the addition of a 10th criterion that ensures that a new vaccine mandate relates in some manner to increasing safety in the school environment.

    The National Immunization Information Hotline (NIIH) has been providing information regarding immunizations to the public and to health care professionals since March 1997. We describe the operations of the NIIH, its experience over the first two and a half years of operation and lessons learned for other immunization hotlines. From 1998-2000, the hotline answered 246,859 calls. Calls concerning immunization information requests totaled 175,367; data about the calls were collected from 35,102. Approximately a third of the 35,102 calls were from health care providers. Of the remaining calls from the public, the greatest number of calls concerned childhood immunizations. Immunization schedule queries from the public increased 323.0% from 1998 to 2000. While the major goal of the NIIH is to provide accurate and reliable information to the public and to health care providers, data from the hotline can be used to monitor changes over time in calls concerning inquiries about the immunization schedule in addition to other variables of interest.

  13. TLR Stimulation of Bone Marrow Lymphoid Precursors from Childhood Acute Leukemia Modifies Their Differentiation Potentials

    Directory of Open Access Journals (Sweden)

    Elisa Dorantes-Acosta

    2013-01-01

    Full Text Available Acute leukemias are the most frequent childhood malignancies worldwide and remain a leading cause of morbidity and mortality of relapsed patients. While remarkable progress has been made in characterizing genetic aberrations that may control these hematological disorders, it has also become clear that abnormalities in the bone marrow microenvironment might hit precursor cells and contribute to disease. However, responses of leukemic precursor cells to inflammatory conditions or microbial components upon infection are yet unexplored. Our previous work and increasing evidence indicate that Toll-like receptors (TLRs in the earliest stages of lymphoid development in mice and humans provide an important mechanism for producing cells of the innate immune system. Using highly controlled co-culture systems, we now show that lymphoid precursors from leukemic bone marrow express TLRs and respond to their ligation by changing cell differentiation patterns. While no apparent contribution of TLR signals to tumor progression was recorded for any of the investigated diseases, the replenishment of innate cells was consistently promoted upon in vitro TLR exposure, suggesting that early recognition of pathogen-associated molecules might be implicated in the regulation of hematopoietic cell fate decisions in childhood acute leukemia.

    It is widely held that Bayesian decision theory is the final word on how a rational person should make decisions. However, Leonard Savage--the inventor of Bayesian decision theory--argued that it would be ridiculous to use his theory outside the kind of small world in which it is always possible to ""look before you leap."" If taken seriously, this view makes Bayesian decision theory inappropriate for the large worlds of scientific discovery and macroeconomic enterprise. When is it correct to use Bayesian decision theory--and when does it need to be modified? Using a minimum of mathematics,

  16. Childhood asthma and risk factors

    Directory of Open Access Journals (Sweden)

    Ljuština-Pribić Radmila

    2010-01-01

    Full Text Available Introduction. This article summarizes the contribution of epidemiology to the understanding of childhood asthma. The first task in epidemiology is to determine prevalence and incidence of any disease. Prevalence. Epidemiological investigations are aimed at evaluating hypotheses about causes of disease by defining demographic characteristics of a certain population as well as by determining possible effects of environmental factors. In spite of some limitations, data obtained by epidemiological investigations have been valuable in confirming both the increasing incidence of asthma and the differences in prevalence in certain population groups. The observance of this phenomenon has led to much speculation and a lot of attempts to identify the reasons behind the rising prevalence. Risk factors. Epidemiological studies have identified risk factors for the development of childhood asthma and provided insight into natural history of disease and prognosis. Factors ranging from increased numbers of immunizations to increased air pollution have been suggested, but subsequent analysis has failed to provide the supporting evidence to implicate most of these possibilities. The concept known as the hygiene hypothesis has gained some support from epidemiological studies. Conclusion. The development of asthma as well as its severity are affected by numerous factors and their interactions can be explained by the heterogeneous nature of this disease.

    Kaposi sarcoma (KS) is an endothelial malignancy caused by human herpes virus-8 (HHV-8) infection. The epidemic and iatrogenic forms of childhood KS result from a profound and acquired T cell deficiency. Recent studies have shown that classic KS of childhood can result from rare single-gene inborn errors of immunity, with mutations in WAS, IFNGR1, STIM1, and TNFRSF4. The pathogenesis of the endemic form of childhood KS has remained elusive. We review childhood KS pathogenesis and its relationship to inherited and acquired immunodeficiency to oncogenic HHV-8.

    Childhood brain tumors are the most common pediatric solid tumor and include several histologic subtypes. Although progress has been made in improving survival rates for some subtypes, understanding of risk factors for childhood brain tumors remains limited to a few genetic syndromes and ionizing radiation to the head and neck. In this report, we review descriptive and analytical epidemiology childhood brain tumor studies from the past decade and highlight priority areas for future epidemiology investigations and methodological work that is needed to advance our understanding of childhood brain tumor causes. Specifically, we summarize the results of a review of studies published since 2004 that have analyzed incidence and survival in different international regions and that have examined potential genetic, immune system, developmental and birth characteristics, and environmental risk factors.

    Full Text Available BACKGROUND : Immunization is the most cost effective public health intervention to reduce childhood morbidity and mortality. Thousands of children can be saved from vaccine preventable diseases each year by immunization. The knowledge of mothers’ is an important factor for better immunization coverage. Less knowledge affects decision making regarding immunization. OBJECTIVES: To assess the knowledge about immunization of under five children among mothers a ttending outpatient department of paediatrics in a tertiary care hospital in Kollam, Kerala and to find out the association of the knowledge level of mothers with some selected variables. MATERIAL AND METHODS : A Cross sectional study was done among mothers of under five children attending the OPD of pediatrics in a tertiary care hospital in Kollam, Kerala from 1 st to 30 th May, 2014. The sample size was 210 and simple random sampling was used. Statistical analysis was done and chi - square test & percentages w ere calculated. RESULT: 93.8% of mothers knew that vaccines are beneficial for their child. 58% were aware about the side effects of few vaccines. 50% of mothers believed that as polio is eradicated from India, there is no need to give polio vaccine. 35% o f mothers acquired knowledge regarding immunization through health workers. All of them had knowledge about polio vaccine but only half of them knew about rotavirus vaccine. 60% mothers believed that multiple vaccines are beneficial although 26% hold their view that it has no benefit at all. 39.5% of mothers’ had adequate knowledge about immunization. It was positively associated with education, working class and high socio - economic status of mothers. CONCLUSION: There are several loopholes in the mother’s knowledge regarding immunization. Many of them had no knowledge about optional vaccines. There is a need to improve knowledge regarding immunization among general population. Adequate information about completin g the

  19. Herd immunity: recent uses in vaccine assessment.

    Science.gov (United States)

    2008-12-01

    Human communities defend themselves against specific infectious agents in a way that extends beyond the simple sum of the immune status of its individuals. By analogy with individual immunity to specific agents, the community level of immunity may vary from complete susceptibility to full protection. Herd immunity has been used to name this community property, which is the result of evolution through natural selection, leading to relationships between two species, typical of prey-predator systems. Varying uses of the term herd immunity led to the use of other expressions, such as herd protection, herd effect and community immunity. Knowledge derived from observational studies and models on herd immunity has supported decisions on the choice of vaccines and vaccination strategies for the benefit of populations. This knowledge is most likely to be extended in the future, with far-reaching effects.

    2013-01-01

    Full Text Available One of the widely used methods for classification that is a decision-making process is artificial immune systems. Artificial immune systems based on natural immunity system can be successfully applied for classification, optimization, recognition, and learning in real-world problems. In this study, a reinforcement learning based artificial immune classifier is proposed as a new approach. This approach uses reinforcement learning to find better antibody with immune operators. The proposed new approach has many contributions according to other methods in the literature such as effectiveness, less memory cell, high accuracy, speed, and data adaptability. The performance of the proposed approach is demonstrated by simulation and experimental results using real data in Matlab and FPGA. Some benchmark data and remote image data are used for experimental results. The comparative results with supervised/unsupervised based artificial immune system, negative selection classifier, and resource limited artificial immune classifier are given to demonstrate the effectiveness of the proposed new method.

    Julian R. Naglik

    2014-01-01

    Full Text Available The human pathogenic fungus Candida albicans is the predominant cause of both superficial and invasive forms of candidiasis. C. albicans primarily infects immunocompromised individuals as a result of either immunodeficiency or intervention therapy, which highlights the importance of host immune defences in preventing fungal infections. The host defence system utilises a vast communication network of cells, proteins, and chemical signals distributed in blood and tissues, which constitute innate and adaptive immunity. Over the last decade the identity of many key molecules mediating host defence against C. albicans has been identified. This review will discuss how the host recognises this fungus, the events induced by fungal cells, and the host innate and adaptive immune defences that ultimately resolve C. albicans infections during health.

  2. Chronic Low-Grade Inflammation in Childhood Obesity Is Associated with Decreased IL-10 Expression by Monocyte Subsets

    2016-01-01

    Chronic low-grade inflammation is related to the development of comorbidities and poor prognosis in obesity. Monocytes are main sources of cytokines and play a pivotal role in inflammation. We evaluated monocyte frequency, phenotype and cytokine profile of monocyte subsets, to determine their association with the pathogenesis of childhood obesity. Children with obesity were evaluated for biochemical and anthropometric parameters. Monocyte subsets were characterized by flow cytometry, considering cytokine production and activation/recognition molecules. Correlation analysis between clinical parameters and immunological data delineated the monocytes contribution for low-grade inflammation. We observed a higher frequency of non-classical monocytes in the childhood obesity group (CO) than normal-weight group (NW). All subsets displayed higher TLR4 expression in CO, but their recognition and antigen presentation functions seem to be diminished due to lower expression of CD40, CD80/86 and HLA-DR. All subsets showed a lower expression of IL-10 in CO and correlation analyses showed changes in IL-10 expression profile. The lower expression of IL-10 may be decisive for the maintenance of the low-grade inflammation status in CO, especially for alterations in non-classical monocytes profile. These cells may contribute to supporting inflammation and loss of regulation in the immune response of children with obesity. PMID:27977792

  3. The impact of changing medicaid enrollments on New Mexico's Immunization Program.

    Directory of Open Access Journals (Sweden)

    Michael A Schillaci

    Full Text Available BACKGROUND: Immunizations are an important component to pediatric primary care. New Mexico is a relatively poor and rural state which has sometimes struggled to achieve and maintain its childhood immunization rates. We evaluated New Mexico's immunization rates between 1996 and 2006. Specifically, we examined the increase in immunization rates between 2002 and 2004, and how this increase may have been associated with Medicaid enrollment levels, as opposed to changes in government policies concerning immunization practices. METHODS AND FINDINGS: This study examines trends in childhood immunization coverage rates relative to Medicaid enrollment among those receiving Temporary Assistance for Needy Families (TANF in New Mexico. Information on health policy changes and immunization coverage was obtained from state governmental sources and the National Immunization Survey. We found statistically significant correlations varying from 0.86 to 0.93 between immunization rates and Medicaid enrollment. CONCLUSIONS: New Mexico's improvement and subsequent deterioration in immunization rates corresponded with changing Medicaid coverage, rather than the state's efforts to change immunization practices. Maintaining high Medicaid enrollment levels may be important for achieving high childhood immunization levels.

  4. Economic Evaluation of Childhood Obesity Interventions: Reflections and Suggestions.

    Science.gov (United States)

    Frew, Emma

    2016-08-01

    Rising levels of childhood obesity present a serious global public health problem amounting to 7 % of GDP in developed countries and affecting 14 % of children. As such, many countries are investing increasingly large quantities of resource towards treatment and prevention. Whilst it is important to demonstrate the clinical effectiveness of any intervention, it is equally as important to demonstrate cost effectiveness as policy makers strive to get the best value for money from increasingly limited public resources. Economic evaluation assists with making these investment decisions and whilst it can offer considerable support in many healthcare contexts, applying it to a childhood obesity context is not straightforward. Childhood obesity is a complex disease with interventions being multi-component in nature. Furthermore, the interventions are implemented in a variety of settings such as schools, the community, and the home, and have costs and benefits that fall outside the health sector. This paper provides a reflection from a UK perspective on the application of the conventional approach to economic evaluation to childhood obesity. It offers suggestions for how evaluations should be designed to fit better within this context, and to meet the needs of local decision makers. An excellent example is the need to report costs using a micro-costing format and for benefit measurement to go beyond a health focus. This is critical as the organisation and commissioning of childhood obesity services is done from a Local Authority setting and this presents further challenges for what is the most appropriate economic evaluation approach to use. Given that adult obesity is now of epidemic proportions, the accurate assessment of childhood obesity interventions to support public health decision making is critical.

    2010-09-01

    Food allergy is a frequent problem in childhood and its prevalence is increasing. In most cases food allergy is an IgE-mediated hypersensitivity response that cause skin reactions as urticaria. Subacute or chronic disorders have generally a not IgE mediated mechanism. Milk is the most common food allergen in USA and UK followed by egg, peanut and walnuts. Sensitization to milk or egg in infancy is associated with an increased risk to develop house dust mite sensitization and asthma later in childhood. Commensal gut flora play a role in induction of oral tolerance and the importance of the intestinal microbiota in the development of food allergy is essential in early ages, when the mucosal barrier and immune system are still immature. Probiotics interact with the mucosal immune system by the same pathways as commensal bacteria. Recent study show that probiotic bacteria induced in vivo increased plasma levels IL-10 and total IgA in children with allergic predisposition. Many clinical studies reporting significant benefits by probiotics supplementation in food allergy prevention and management but not everyone agree on their effectiveness. These differences are probably related to differences in selected populations and in probiotic strains used.

    Recently the Danish subway trains have begun to announce “on time” when they arrive at a station on time. This action reflects a worrying acceptance of the normality of failure. If trains were generally expected to be on time, there would be no reason to – triumphantly – announce it. This chapter...... as a controlled cost for achieving organizational goals. Decisions must fail so the organization can succeed. This chapter uses two cases to elaborate on these ideas.

    Chatterjee, Tathagata; Choudhry, V P

    2013-09-01

    Myelodysplastic syndrome (MDS) comprises of a heterogeneous group of bone marrow disorders resulting from a clonal stem cell defect characterised by cytopenias despite a relatively hypercellular marrow, ineffective hematopoiesis, morphological dysplasia in the marrow elements, no response to hematinics such as iron, B12 or folic acid and risk of progression to leukemia. Myelodysplastic syndrome in childhood is extremely rare and accounts for less than 5% of all hematopoietic neoplasms in children below the age of 14 y. The primary MDS in children, also known as de novo MDS differs from secondary MDS which generally follows congenital or acquired bone marrow (BM) failure syndromes as well as from therapy related MDS, commonly resulting from cytotoxic therapy. MDS associated with Down syndrome which accounts for approximately one-fourth of cases of childhood MDS is now considered a unique biologic entity synonymous with Down syndrome-related myeloid leukemia and is biologically distinct from other cases of childhood MDS. Refractory cytopenia of childhood (RCC) is the commonest type of MDS. Genetic changes predisposing to MDS in childhood remain largely obscure. Monosomy 7 is by-far the commonest cytogenetic abnormality associated with childhood MDS; however most cases of RCC show a normal karyotype. Complex cytogenetic abnormalities and trisomy 8 and trisomy 21 are also occasionally observed. The most effective and curative treatment is Hematopoietic stem cell transplantation and this is particularly effective in children with the monosomy 7 genetic defect as well as those displaying complex karyotype abnormalities provided it is instituted early in the course of the disease.

  14. Oral zinc and common childhood infections--An update.

    Basnet, Sudha; Mathisen, Maria; Strand, Tor A

    2015-01-01

    Zinc is an essential micronutrient important for growth and for normal function of the immune system. Many children in developing countries have inadequate zinc nutrition. Routine zinc supplementation reduces the risk of respiratory infections and diarrhea, the two leading causes of morbidity and mortality in young children worldwide. In childhood diarrhea oral zinc also reduces illness duration and risk of persistent episodes. Oral zinc is therefore recommended for the treatment of acute diarrhea in young children. The results from the studies that have measured the therapeutic effect of zinc on acute respiratory infections, however, are conflicting. Moreover, the results of therapeutic zinc for childhood malaria also are so far not promising.This paper gives a brief outline of the current evidence from clinical trials on therapeutic effect of oral zinc on childhood respiratory infections, pneumonia and malaria and also of new evidence of the effect on serious bacterial illness in young infants.

Few measures in preventive medicine are of such proven value and as easy to implement as routine immunization against infectious diseases. Prevention of infection by immunization is a lifelong process. There are a number of vaccines that all adults (¡I18 years require. There are also other vaccines that need to be tailored to meet individual variations in risk resulting from occupation, foreign travel, underlying illness, lifestyle and age.

  17. Immunization Milestones: A More Comprehensive Picture of Age-Appropriate Vaccination

    Directory of Open Access Journals (Sweden)

    Steve G. Robison

    2010-01-01

    Full Text Available A challenge facing immunization registries is developing measures of childhood immunization coverage that contain more information for setting policy than present vaccine series up-to-date (UTD rates. This study combined milestone analysis with provider encounter data to determine when children either do not receive indicated immunizations during medical encounters or fail to visit providers. Milestone analysis measures immunization status at key times between birth and age 2, when recommended immunizations first become late. The immunization status of a large population of children in the Oregon ALERT immunization registry and in the Oregon Health Plan was tracked across milestone ages. Findings indicate that the majority of children went back and forth with regard to having complete age-appropriate immunizations over time. We also found that immunization UTD rates when used alone are biased towards relating non-UTD status to a lack of visits to providers, instead of to provider visits on which recommended immunizations are not given.

  18. Psychoneuroimmunology of Early-Life Stress: The Hidden Wounds of Childhood Trauma?

    Science.gov (United States)

    Danese, Andrea; J Lewis, Stephanie

    2017-01-01

    The brain and the immune system are not fully formed at birth, but rather continue to mature in response to the postnatal environment. The two-way interaction between the brain and the immune system makes it possible for childhood psychosocial stressors to affect immune system development, which in turn can affect brain development and its long-term functioning. Drawing from experimental animal models and observational human studies, we propose that the psychoneuroimmunology of early-life stress can offer an innovative framework to understand and treat psychopathology linked to childhood trauma. Early-life stress predicts later inflammation, and there are striking analogies between the neurobiological correlates of early-life stress and of inflammation. Furthermore, there are overlapping trans-diagnostic patterns of association of childhood trauma and inflammation with clinical outcomes. These findings suggest new strategies to remediate the effect of childhood trauma before the onset of clinical symptoms, such as anti-inflammatory interventions and potentiation of adaptive immunity. Similar strategies might be used to ameliorate the unfavorable treatment response described in psychiatric patients with a history of childhood trauma.

    In the paper, authors presents a greedy algorithm for construction of exact and partial decision rules for decision tables with many-valued decisions. Exact decision rules can be \\'over-fitted\\', so instead of exact decision rules with many attributes, it is more appropriate to work with partial decision rules with smaller number of attributes. Based on results for set cover problem authors study bounds on accuracy of greedy algorithm for exact and partial decision rule construction, and complexity of the problem of minimization of decision rule length. © 2011 Springer-Verlag.

  1. Rethinking the benefits and costs of childhood vaccination: the example of the Haemophilus influenzae type b vaccine.

    Bärnighausen, Till; Bloom, David E; Canning, David; Friedman, Abigail; Levine, Orin S; O'Brien, Jennifer; Privor-Dumm, Lois; Walker, Damian

    2011-03-16

    Economic evaluations of health interventions, such as vaccinations, are important tools for informing health policy. Approaching the analysis from the appropriate perspective is critical to ensuring the validity of evaluation results for particular policy decisions. Using the example of cost-benefit analysis (CBA) of Haemophilus influenzae type b (Hib) vaccination, we demonstrate that past economic evaluations have mostly adopted narrow evaluation perspectives, focusing primarily on health gains, health-care cost savings, and reductions in the time costs of caring, while usually ignoring other important benefits including outcome-related productivity gains (improved economic productivity due to prevention of mental and physical disabilities), behavior-related productivity gains (economic growth due to fertility reductions as vaccination improves child survival), and community externalities (herd immunity and prevention of antibiotic resistance). We further show that potential cost reductions that could be attained through changes in the delivery of the Hib vaccine have also generally been ignored in economic evaluations. Future economic evaluations of childhood vaccinations should take full account of benefits and costs, so that policymakers have sufficient information to make well-informed decisions on vaccination implementation.

    The societal consensus that has supported the United States' universal childhood immunization programs for the past 50 years shows signs of eroding. This article proposes a systematic approach to evaluate immunization policy options. Through a unifying framework that combines epidemiologic, economic, and ethical concerns, this approach promotes a clearer understanding of underlying issues and inherent tradeoffs between alternative policies. Such a systematic examination of policy options could facilitate the public dialogue necessary to continually recreate a broad consensus on immunization practices and enable us to choose policies most in accord with our fundamental values.

    Kotagal, Suresh

    2009-04-01

    Common childhood parasomnias, including those occurring at sleep onset and during rapid eye movement sleep or non-rapid eye movement sleep and their ontogeny are discussed. The events may be distressing to both the patient and family members. Stereotypic movements characteristic of some parasomnias most likely arise from disinhibition of subcortical central pattern generators. Genetic predisposition, an inherent instability of non-rapid eye movement sleep and underlying sleep disturbances such as obstructive sleep apnea may predispose to the activation of confusional arousals, sleep walking or sleep terrors. Many parasomnias can be recognized by history alone, but some require nocturnal polysomnography for appropriate diagnosis and management. A scheme to distinguish non-rapid eye movement sleep parasomnias from nocturnal seizures is provided. Behavioral therapy has a role in the management of many childhood parasomnias, but evidence based recommendations are as yet unavailable.

  5. Genetics of Childhood Obesity

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Obesity is a major health problem and an immense economic burden on the health care systems both in the United States and the rest of the world. The prevalence of obesity in children and adults in the United States has increased dramatically over the past decade. Besides environmental factors, genetic factors are known to play an important role in the pathogenesis of obesity. Genome-wide association studies (GWAS have revealed strongly associated genomic variants associated with most common disorders; indeed there is general consensus on these findings from generally positive replication outcomes by independent groups. To date, there have been only a few GWAS-related reports for childhood obesity specifically, with studies primarily uncovering loci in the adult setting instead. It is clear that a number of loci previously reported from GWAS analyses of adult BMI and/or obesity also play a role in childhood obesity.

    Full Text Available Dental caries is one of the most common childhood diseases, and people continue to be susceptible to it throughout their lives. Although dental caries can be arrested and potentially even reversed in its early stages, it is often not self-limiting and progresses without proper care until the tooth is destroyed. Early childhood caries (ECC is often complicated by inappropriate feeding practices and heavy infection with mutans streptococci. Such children should be targeted with a professional preventive program that includes oral hygiene instructions for mothers or caregivers, along with fluoride and diet counseling. However, these strategies alone are not sufficient to prevent dental caries in high-risk children; prevention of ECC also requires addressing the socioeconomic factors that face many families in which ECC is endemic. The aim of this paper is to systematically review information about ECC and to describe why many children are suffering from dental caries.

    2013-10-01

    Cardiovascular disease (CVD) is the leading cause of mortality worldwide, accounting for 16.7 million deaths each year. The underlying cause of the majority of CVD is atherosclerosis. In the past, atherosclerosis was considered to be the result of passive lipid accumulation in the vessel wall. Today's picture is far more complex. Atherosclerosis is considered a chronic inflammatory disease that results in the formation of plaques in large and mid-sized arteries. Both cells of the innate and the adaptive immune system play a crucial role in its pathogenesis. By transforming immune cells into pro- and anti-inflammatory chemokine- and cytokine-producing units, and by guiding the interactions between the different immune cells, the immune system decisively influences the propensity of a given plaque to rupture and cause clinical symptoms like myocardial infarction and stroke. In this review, we give an overview on the newest insights in the role of different immune cells and subtypes in atherosclerosis.

Vertical handoffs between the WLAN and the cellular network could occur frequently, with regard to vertical handoff performance, there is a critical need for developing algorithms for connection management and optimal resource allocation for seamless mobility. In this paper, we develop a mathematical model for vertical handoff decision problem, propose an artificial simple harmonic oscillator immune algorithm-based vertical handoff decision scheme, and perform the simulation experiments to validate proposed solution. Experimental result shows that the proposed solution, compared with literature solutions, can not only balance the overall load among all networks but also increase the collective battery lifetime of mobile terminals, and has the advantage of good application value.%本文设计了垂直切换判决方案问题的数学模型,给出了一种基于简谐振子免疫优化算法的垂直切换判决方案.并与文献方案进行了对比实验实验结果表明,本文方案能够有效地平衡网络负载、增加终端电池的生存时间,具有较好的应用价值.

    Childhood obesity has increased dramatically during the past two decades. The growing incidence of childhood obesity is alarming, given the significant short and long term health problems associated with obesity. Being overweight or obese may increase the rate of non-communicable diseases such as type 2 diabetes and cardiovascular disease in adulthood. It may contribute to shortening life expectancy and adversely affects the quality of life. Therefore, it is important to prevent childhood obe...

    2014-01-01

    Probiotic organisms are claimed to offer several functional properties including stimulation of immune system. This review is presented to provide detailed informations about how probiotics stimulate our immune system. Lactobacillus rhamnosus GG, Lactobacillus casei Shirota, Bifidobacterium animalis Bb-12, Lactobacillus johnsonii La1, Bifidobacterium lactis DR10, and Saccharomyces cerevisiae boulardii are the most investigated probiotic cultures for their immunomodulation properties. Probiotics can enhance nonspecific cellular immune response characterized by activation of macrophages, natural killer (NK) cells, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in strain-specific and dose-dependent manner. Mixture and type (gram-positive and gram-negative) of probiotic organisms may induce different cytokine responses. Supplementation of probiotic organisms in infancy could help prevent immune-mediated diseases in childhood, whereas their intervention in pregnancy could affect fetal immune parameters, such as cord blood interferon (IFN)-γ levels, transforming growth factor (TGF)-β1 levels, and breast milk immunoglobulin (Ig)A. Probiotics that can be delivered via fermented milk or yogurt could improve the gut mucosal immune system by increasing the number of IgA(+) cells and cytokine-producing cells in the effector site of the intestine.

  6. Decision theory and decision behaviour

    CERN Document Server

    Rapoport, Anatol

    1998-01-01

    The book treats two approaches to decision theory: (1) the normative, purporting to determine how a 'perfectly rational' actor ought to choose among available alternatives; (2) the descriptive, based on observations of how people actually choose in real life and in laboratory experiments. The mathematical tools used in the normative approach range from elementary algebra to matrix and differential equations. Sections on different levels can be studied independently. Special emphasis is made on 'offshoots' of both theories to cognitive psychology, theoretical biology, and philosophy.

    As the average life expectancy increases, retired people want to travel. Five to 8% of travellers in tropical areas are old persons. Immune system suffers of old age as the other organs. The number and the functions of the T-lymphocytes decrease, but the B-lymphocytes are not altered. So, the response to the vaccinations is slower and lower in the elderly. Influenza is a great cause of death rate in old people. The seroconversion, after vaccine, is 50% from 60 to 70 years old, 31% from 70 to 80 years old, and only 11% after 80 years old. But in public health, the vaccination reduced the morbidity by 25%, admission to hospital by 20%, pneumonia by 50%, and mortality by 70%. Antipoliomyelitis vaccine is useful for travellers, as the vaccines against hepatitis and typhoid fever. Pneumococcal vaccine is effective in 60%. Tetanus is fatal in at last 32% of the people above 80 years, therefore this vaccine is very important.

    2012-02-01

    Subclinical hypothyroidism (SH) is defined as an elevated thyroid stimulating hormone (TSH) in association with a normal total or free thyroxine (T4) or triiodothyronine (T3). It is frequently encountered in both neonatology and general paediatric practice; however, its clinical significance is widely debated. Currently there is no broad consensus on the investigation and treatment of these patients; specifically who to treat and what cut-off level of TSH should be used. This paper reviews the available evidence regarding investigation, treatments and outcomes reported for childhood SH.

    Background Since the 2008 inception of universal childhood influenza vaccination, national rates have risen more dramatically among younger children than older children and reported rates across racial/ethnic groups are inconsistent. Interventions may be needed to address age and racial disparities to achieve the recommended childhood influenza vaccination target of 70%. Purpose To evaluate an intervention to increase childhood influenza vaccination across age and racial groups. Methods In 2011–2012, 20 primary care practices treating children were randomly assigned to Intervention and Control arms of a cluster randomized controlled trial to increase childhood influenza vaccination uptake using a toolkit and other strategies including early delivery of donated vaccine, in-service staff meetings, and publicity. Results The average vaccination differences from pre-intervention to the intervention year were significantly larger in the Intervention arm (n=10 practices) than the Control arm (n=10 practices), for children aged 2–8 years (10.2 percentage points (pct pts) Intervention vs 3.6 pct pts Control) and 9–18 years (11.1 pct pts Intervention vs 4.3 pct pts Control, p<0.05), for non-white children (16.7 pct pts Intervention vs 4.6 pct pts Control, p<0.001), and overall (9.9 pct pts Intervention vs 4.2 pct pts Control, p<0.01). In multi-level modeling that accounted for person- and practice-level variables and the interactions among age, race and intervention, the likelihood of vaccination increased with younger age group (6–23 months), white race, commercial insurance, the practice’s pre-intervention vaccination rate, and being in the Intervention arm. Estimates of the interaction terms indicated that the intervention increased the likelihood of vaccination for non-white children in all age groups and white children aged 9–18 years. Conclusions A multi-strategy intervention that includes a practice improvement toolkit can significantly improve influenza

    Prescriptive Bayesian decision making has reached a high level of maturity and is well-supported algorithmically. However, experimental data shows that real decision makers choose such Bayes-optimal decisions surprisingly infrequently, often making decisions that are badly sub-optimal. So prevalent is such imperfect decision-making that it should be accepted as an inherent feature of real decision makers living within interacting societies. To date such societies have been investigated from an economic and gametheoretic perspective, and even to a degree from a physics perspective. However, lit

  15. Management of childhood stuttering.

    2013-02-01

    Stuttering is a speech disorder that begins during the first years of life and is among the most prevalent of developmental disorders. It appears to be a problem with neural processing of speech involving genetics. Onset typically occurs during the first years of life, shortly after language development begins. Clinical presentation during childhood is interrupted and effortful speech production, often with rapid onset. If not corrected during early childhood, it becomes intractable and can cause psychological, social, educational and occupational problems. There is evidence from replicated clinical trials to support early intervention during the pre-school years. Meta-analysis of studies indicates that children who receive early intervention during the pre-school years are 7.7 times more likely to have resolution of their stuttering. Early intervention is recommended with a speech pathologist. Some children who begin to stutter will recover without such intervention. However, the number of such recoveries is currently not known, and it is not possible to predict which children are likely to recover naturally. Consequently, the current best practice is for speech pathologists to monitor children for signs of natural recovery for up to 1 year before beginning treatment.

    The results of CT in 100 patients with acute hemiplegia in childhood are reported here. The etiology was various: 2 patients had infratentorial brain tumors, 56 had cerebral vascular diseases, 3 had head injuries, 16 had intracranial infectious diseases, one had postinfectious encephalomyelitis, one had multiple sclerosis, 2 had epilepsy, and the diagnosis of 19 were unknown. Eleven patients had a normal CT and a good prognosis. As for the type of onset, there were patients of type 1 with fever and 42 with convulsions and unconsciousness; those of type 2 with convulsions and unconsciousness were 12, and those of type 3 without fever and convulsions were 46. This classification is assumed to be useful, as the type of onset is characteristic of the etiology. Six patients were diagnosed correctly by repeated examinations, although the first CT did not reveal any remarkable findings. Capsular infarction, occlusion of the posterior cerebral artery in acute hemiplegia in childhood, abnormal findings of the internal capsule, thalamus, and midbrain in a patient with postinfectious encephalomyelitis, and a diffuse low density in the CT of the unilateral hemisphere in the patients with acute encephalopathy and acute hemiplegia of an obscure origin have been found after the introduction of computerized tomography.

  17. Adult immunization in India: Importance and recommendations.

    Verma, Ramesh; Khanna, Pardeep; Chawla, Suraj

    2015-01-01

    Vaccination is recommended throughout life to prevent infectious diseases and their sequelae. Vaccines are crucial to prevent mortality in that >25% of deaths are due to infections. Vaccines are recommended for adults on the basis of a range of factors. Substantial improvement and increases in adult vaccination are needed to reduce the health consequences of vaccine-preventable diseases among adults. Incomplete and inadequate immunization in India against these communicable diseases results in substantial and unnecessary costs both in terms of hospitalization and treatment. The government of India as well as the World Health Organization (WHO) consider childhood vaccination as the first priority, but there is not yet focus on adult immunization. Adult immunization in India is the most ignored part of heath care services. The Expert Group recommended that data on infectious diseases in India should be updated, refined, and reviewed periodically and published regularly. This group suggested that the consensus guidelines about adult immunization should be reviewed every 3 years to incorporate new strategies from any emerging research from India. There is an immediate need to address the problem of adult immunization in India. Although many issues revolving around efficacy, safety, and cost of introducing vaccines for adults at the national level are yet to be resolved, there is an urgent need to sensitize the health planners as well as health care providers regarding this pertinent issue.

Taking this into consideration, the present study was based on the following question: what practical contributions to clinicians and researchers does the current literature on childhood depression have to offer? The objective of the present study was to conduct a systematic review of articles regarding childhood depression. To accomplish this purpose, a systematic review of articles on childhood depression, published from January 1, 2010 to November 24, 2012, on MEDLINE and SciELO databases was carried out. Search terms were “depression” (medical subject headings [MeSH], “child” (MeSH, and "childhood depression" (keyword. Of the 180 retrieved studies, 25 met the eligibility criteria.

    The childhood cancer experiences of stepfamilies have not been described despite the fact that nearly one third of U.S. children will live in a stepfamily household. To describe the impact of diagnosis on parental relationships in stepfamilies, we undertook a secondary analysis of data from a study of parental decision making in structurally diverse families. As described by 13 parents of six stepfamilies, the crisis of a childhood cancer diagnosis immediately changed family dynamics. Parental relationships changed, which shifted family boundaries, creating instability in families who were trying to cope with a very stressful life experience. Through increased understanding of parental relationship changes that occur after the diagnosis of childhood cancer in stepfamilies, clinicians can anticipate these changes and provide supportive interventions to reduce overall family conflict and distress. These distinctive stepfamily responses underscore the need to include structurally diverse families in future trials targeting parental coping in childhood cancer.

  1. Explaining socio-economic inequalities in immunization coverage in Nigeria.

    2016-11-01

    Globally, in 2013 over 6 million children younger than 5 years died from either an infectious cause or during the neonatal period. A large proportion of these deaths occurred in developing countries, especially in sub-Saharan Africa. Immunization is one way to reduce childhood morbidity and deaths. In Nigeria, however, although immunization is provided without a charge at public facilities, coverage remains low and deaths from vaccine preventable diseases are high. This article seeks to assess inequalities in full and partial immunization coverage in Nigeria. It also assesses inequality in the 'intensity' of immunization coverage and it explains the factors that account for disparities in child immunization coverage in the country. Using nationally representative data, this article shows that disparities exist in the coverage of immunization to the advantage of the rich. Also, factors such as mother's literacy, region and location of the child, and socio-economic status explain the disparities in immunization coverage in Nigeria. Apart from addressing these issues, the article notes the importance of addressing other social determinants of health to reduce the disparities in immunization coverage in the country. These should be in line with the social values of communities so as to ensure acceptability and compliance. We argue that any policy that addresses these issues will likely reduce disparities in immunization coverage and put Nigeria on the road to sustainable development.

    Full Text Available Abstract Background The Advisory Committee on Immunization Practices advocates that influenza immunization is the most effective method for prevention of illness due to influenza. Recommendations for vaccination of children against influenza have been revised several times since 2002, and as of 2008 include all children 6 months to 18 years of age. Nevertheless, influenza immunization rates have remained low. Methods We surveyed practicing pediatricians in Maryland in the spring of 2007 to determine their attitudes and practices toward childhood influenza immunization. Results The overall response to the survey was 21%. A total of 61% of respondents reported that immunization either is cost neutral or produces a loss, and 36.6% noted it was minimally profitable. Eighty-six percent of respondents were receptive to supporting school-based immunization programs, and 61% indicated that they would participate in such programs. Respondents reported higher rates of immunization of select patient groups than those noted by the Centers for Disease Control and Prevention Conclusion Vaccination was reported to occur at multiple types of patient encounters, as recommended. Survey respondents stated that practice-based immunization was not a profitable service. Pediatricians were supportive of school-based immunization programs, and more than half stated they would be actively involved in such programs. School-based programs may be critical to achieving high vaccination coverage in the school-aged population.

    Individual immunity is a powerful force affecting host health and pathogen evolution. Importantly, the effects of individual immunity also scale up to affect pathogen transmission dynamics and the success of vaccination campaigns for entire host populations. Population-scale immunity is often termed 'herd immunity'. Here we outline how individual immunity maps to population outcomes and discuss implications for control of infectious diseases. Particular immunological characteristics may be more or less likely to result in a population level signature of herd immunity; we detail this and also discuss other population-level outcomes that might emerge from individual-level immunity.

    Full Text Available Sexual abuse is defined as use of child or adolescent by the adults for satisfying of sexual urges and needs with forcing, threatening or tricking. Sexual abuse can be in the form of sexual abuse without touch, sexual touch, interfemoral intercourse, sexual penetration, and sexual exploitation. The prevalence of sexual abuse is reported as 10-40%. It is seen in female four times more than in males. Abusers are frequently male, only 5-15% of them are female. The abuse by females is usually towards male child. Thirty-fifty percent of abuse cases among child and adolescent are outside the family including strangers or familiar person. Some features of abusers are introvert personality, pedophilic and antisocial personality. Most of the abusers have a history of sexual abuse or aggression during childhood. Sexual intercourse between two people who are not allowed to marry by law is called as incest. Family pattern of incest is defined globally as disorganized and dysfunctional. The most commonly reported familial pattern is rigid and patriarchal family pattern with a harsh father using force quite frequently. The clinical features and impacts of the sexual abuse on the child varies according to the relation between abusers and the child, form of abuse, duration of abuse, presence of physical assault, developmental phase, child age and psychological development before the abuse. Sexual abuse history may result in psychiatric disorders including anxiety, depression, substance dependence, suicide act, borderline personality disorder, posttraumatic stress disorder. Abuse negatively affects interpersonal relationships and self esteem of abused individuals. Several studies reported close association between risky sexual behaviors in adulthood and a history of of sexual abuse during childhood. Four traumatic dynamics including traumatic sexuality with abuse, feeling of betrayal, weakness, and stigmatization exist in childhood abuse. Trauma can cause

    This review focuses on the so-called "periodic syndromes of childhood that are precursors to migraine", as included in the Second Edition of the International Classification of Headache Disorders. Three periodic syndromes of childhood are included in the Second Edition of the International Classification of Headache Disorders: abdominal migraine, cyclic vomiting syndrome and benign paroxysmal vertigo, and a fourth, benign paroxysmal torticollis is presented in the Appendix. The key clinical features of this group of disorders are the episodic pattern and intervals of complete health. Episodes of benign paroxysmal torticollis begin between 2 and 8 months of age. Attacks are characterized by an abnormal inclination and/or rotation of the head to one side, due to cervical dystonia. They usually resolve by 5 years. Benign paroxysmal vertigo presents as sudden attacks of vertigo, accompanied by inability to stand without support, and lasting seconds to minutes. Age at onset is between 2 and 4 years, and the symptoms disappear by the age of 5. Cyclic vomiting syndrome is characterized in young infants and children by repeated stereotyped episodes of pernicious vomiting, at times to the point of dehydration, and impacting quality of life. Mean age of onset is 5 years. Abdominal migraine remains a controversial issue and presents in childhood with repeated stereotyped episodes of unexplained abdominal pain, nausea and vomiting occurring in the absence of headache. Mean age of onset is 7 years. Both cyclic vomiting syndrome and abdominal migraine are noted for the absence of pathognomonic clinical features but also for the large number of other conditions to be considered in their differential diagnoses. Diagnostic criteria, such as those of the Second Edition of the International Classification of Headache Disorders and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition, have made diagnostic approach and management easier.

    rates of risk immunization for all asset and liability portfolios can be achieved by establishing functional relationships between a bank's net value changes, incremental asset and liability, and stock asset-liability duration.The first goal of this study is to minimize the deviation between the duration gaps of all asset-liability portfolios as “O. ” The second goal is to maximize interest incomes of banks' assets. Supervisory policies and regulations are constraints. We constructed an incremental asset portfolio decision-making model based on the risk immunization optimum of all asset-liability interest rates.This paper is made of 5 sections. Section I reviewed current literature on immune conditions of interest rate risks. Section 2 discussed theories on asset and liability portfolio optimization and developed immune conditions to assess interest rate risks based on a bank's net worth function and the duration of incremental stock portfolios. Section 3 discussed incremental asset portfolios based on the risk immunization of asset-liability interest rates. Section 4 modeled the decision-making process and discussed optimal results using real examples. Section 5 concluded this study with major findings and future research directions.This study made two major contributions. First, the proposed interest rate immunization conditions to maximize the return of assetliability portfolios changes the existing ways of controlling partial risks based on incremental asset-liability portfolio. Second, this study replaces duration stock asset-liability terms. Our design can better reflect both incremental asset-liability duration and stock assetliability duration, and solve risk measurement problems of mixed portfolios, including asset-liability incremental portfolio and stock portfolio.

    Full Text Available We have treated 4 cases of pyoderma gangrenosum in infancy and childhood in past 2 years. The ages at onset were 6 months, 8 months, 6 months and 11.5 years respectively. Initial lesions were papulopustular in 3 and nodular in 1 patients but later on all of them developed ulcerative lesions with erythematous, violaceous, infiltrated or undermined edges. The lesions were numerous in 3 patients but few in 1 patient. The first patient had very high leucocyte count. In the second patient skin lesions of PG followed measles vaccinations. We could not reveal any association in the other two patients. None of the patient responded to antibiotic therapy. Three patients were treated successfully with dapsone and one with a combination of dapsone and prednisolone. We conclude that pyoderma gangrenosum is not so rare in infancy and it is more likely to occur without associated systemic diseases.

    Fatty liver is a growing health problem worldwide. It might evolve to nonalcoholic steatohepatitis, cirrhosis and cause hepatocellular carcinoma. This disease, which has increased because of eating habits, changes in food content and lifestyle, affects people from childhood. The most important risk factors are obesity and insulin resistance. Besides these factors, gender, ethnicity, genetic predisposition and some medical problems are also important. Cirrhosis in children is rare but is reported. Nonalcoholic fatty liver disease(NAFLD) has no specific symptoms or signs but should be considered in obese children. NAFLD does not have a proven treatment. Weight loss with family based treatments is the most acceptable management. Exercise and an applicable diet with low glycemic index and appropriate calorie intake are preferred. Drugs are promising but not sufficient in children for today.

  13. Cell mediated immunity to fungi: a reassessment.

    Science.gov (United States)

    Romani, Luigina

    2008-09-01

    Protective immunity against fungal pathogens is achieved by the integration of two distinct arms of the immune system, the innate and adaptive responses. Innate and adaptive immune responses are intimately linked and controlled by sets of molecules and receptors that act to generate the most effective form of immunity for protection against fungal pathogens. The decision of how to respond will still be primarily determined by interactions between pathogens and cells of the innate immune system, but the actions of T cells will feed back into this dynamic equilibrium to regulate the balance between tolerogenic and inflammatory responses. In the last two decades, the immunopathogenesis of fungal infections and fungal diseases was explained primarily in terms of Th1/Th2 balance. Although Th1 responses driven by the IL-12/IFN-gamma axis are central to protection against fungi, other cytokines and T cell-dependent pathways have come of age. The newly described Th17 developmental pathway may play an inflammatory role previously attributed to uncontrolled Th1 responses and serves to accommodate the seemingly paradoxical association of chronic inflammatory responses with fungal persistence in the face of an ongoing inflammation. Regulatory T cells in their capacity to inhibit aspects of innate and adaptive antifungal immunity have become an integral component of immune resistance to fungi, and provide the host with immune defense mechanisms adequate for protection, without necessarily eliminating fungal pathogens which would impair immune memory--or causing an unacceptable level of tissue damage. The enzyme indoleamine 2,3-dioxygenase and tryptophan metabolites contribute to immune homeostasis by inducing Tregs and taming overzealous or heightened inflammatory responses.

    IgE-mediated immediate type reactions are the most common form of food allergy in childhood. Primary (often in early childhood) and secondary (often pollen-associated) allergies can be distinguished by their level of severity. Hen's egg, cow's milk and peanut are the most common elicitors of primary food allergy. Tolerance development in hen's egg and cow's milk allergy happens frequently whereas peanut allergy tends toward a lifelong disease. For the diagnostic patient history, detection of sensitization and (in many cases) oral food challenges are necessary. Especially in peanut and hazelnut allergy component-resolves diagnostic (measurement of specific IgE to individual allergens, e. g. Ara h 2) seem to be helpful. In regard to therapy elimination diet is still the only approved approach. Patient education through dieticians is extremely helpful in this regard. Patients at risk for anaphylactic reactions need to carry emergency medications including an adrenaline auto-injector. Instruction on the usage of the adrenaline auto-injector should take place and a written management plan handed to the patient. Moreover, patients or caregivers should be encouraged to attending a structured educational intervention on knowledge and emergency management. In parallel, causal therapeutic options such as oral, sublingual or epicutaneous immunotherapies are currently under development. In regard to prevention of food allergy current guidelines no longer advise to avoid highly allergenic foods. Current intervention studies are investigating wether early introduction of highly allergic foods is effective and safe to prevent food allergy. It was recently shown that peanut introduction between 4 and 11  months of age in infants with severe atopic dermatitis and/or hen's egg allergy (if they are not already peanut allergic) prevents peanut allergy in a country with high prevalence.

  15. Trends in childhood disease.

    Pallapies, Dirk

    2006-09-28

    Child mortality has declined remarkably during the last decades. While neonatal disorders, diarrhoea, pneumonia, and malaria as well as being underweight account for most of the child deaths worldwide, children's health discussions in Europe and the USA focus on other issues such as asthma, neurodevelopmental disorders, male genital malformations, and childhood cancer. There is clear evidence of increasing rates of asthma in various countries during the last decades, although rates in some countries may now have stabilised or even decline as recent UK data indicate. Although an increase in the frequency of neurodevelopmental disorders such as autism and attention deficit disorder has frequently been discussed, the limited data in this field does not justify such a conclusion. While geographic heterogeneity regarding reproductive outcomes is apparent, global trends have not been identified. Interpretation of the available information on asthma, neurodevelopmental disorders and reproductive outcomes is hampered by inconstant diagnostic criteria over place and time and the lack of good and comprehensive population-based surveillance data, which makes it impossible to ascertain trends in actual disease frequency. Data indicate that developed countries have a gradually increasing incidence in leukaemia with a corresponding drop in the incidence of lymphoma. Increases in brain tumour frequency may be related to the development and wide application of new diagnostic capabilities, rather than a true change in the incidence of malignant disease. With a better prognosis for childhood cancer survival, secondary cancers following chemotherapy appear to be increasing. A wide range of environmental factors is thought to have an impact on children's health. These factors include nutrition (protein, vitamins, antioxidants), lifestyle and behaviour choices such as tobacco and alcohol use, parental health, socio-economic status, choice of living environment (urban versus rural, etc

    Background Early childhood immunizations, although vital for preventative health, are painful and too often lead to fear of needles. Effective pain management strategies during infant immunizations include breastfeeding, sweet solutions, and upright front-to-front holding. However, it is unknown how often these strategies are used in clinical practice. We aimed to review the content of YouTube videos showing infants being immunized to ascertain parents’ and health care professionals’ use of p...

    We are able to identify the different risk factors involved in the development of the disorder from a study of the childhood of a schizophrenic patient. More specifically, we will define the perinatal risk factors: season and place of birth, viral exposure during pregnancy and obstetric complications. Developmental factors will also be discussed. Socialisation, language, psychomotor and cognitive development disorders are all developmental difficulties seen during the childhood of the schizophrenic patient. Finally we will finish by discussing a few psychosocial risk factors.

  7. Modeling collective & intelligent decision making of multi-cellular populations.

    Science.gov (United States)

    Shin, Yong-Jun; Mahrou, Bahareh

    2014-01-01

    In the presence of unpredictable disturbances and uncertainties, cells intelligently achieve their goals by sharing information via cell-cell communication and making collective decisions, which are more reliable compared to individual decisions. Inspired by adaptive sensor network algorithms studied in communication engineering, we propose that a multi-cellular adaptive network can convert unreliable decisions by individual cells into a more reliable cell-population decision. It is demonstrated using the effector T helper (a type of immune cell) population, which plays a critical role in initiating immune reactions in response to invading foreign agents (e.g., viruses, bacteria, etc.). While each individual cell follows a simple adaptation rule, it is the combined coordination among multiple cells that leads to the manifestation of "self-organizing" decision making via cell-cell communication.

  8. Informatics Perspectives on Decision Taking

    CERN Document Server

    Bergstra, J A

    2011-01-01

    A decision is an act or event of decision taking. Decision making always includes decision taking, the latter not involving significant exchanges with non-deciding agents. A decision outcome is a piece of storable information constituting the result of a decision. Decision outcomes are typed, for instance: plan, command, assertion, or boolean reply to a question. A decision effect is any consequence of putting a decision outcome into effect. Decision outcomes must be expected by the decider to lead to certain decision effects, by way of their being put into effect. The availability of a model or of a theory of the causal chain leading from a decision outcome to one or more decision effects is assumed for the decision taker, otherwise the decision outcome is merely an utterance. Decision effectiveness measures the decision effects against objectives meant to be served with the decision. Decision taking is positioned amidst many similar notions including: decision making, decision process, decision making proce...

    In October 2016, the Advisory Committee on Immunization Practices (ACIP) approved the Recommended Immunization Schedule for Children and Adolescents Aged 18 Years or Younger-United States, 2017. The 2017 child and adolescent immunization schedule summarizes ACIP recommendations, including several changes from the 2016 immunization schedules, in three figures, and footnotes for the figures. These documents can be found on the CDC immunization schedule website (https://www.cdc.gov/vaccines/schedules/index.html). These immunization schedules are approved by ACIP (https://www.cdc.gov/vaccines/acip/index.html), the American Academy of Pediatrics (https://www.aap.org), the American Academy of Family Physicians (https://www.aafp.org), and the American College of Obstetricians and Gynecologists (http://www.acog.org). Health care providers are advised to use the figures and the combined footnotes together. The full ACIP recommendations for each vaccine, including contraindications and precautions, can be found at https://www.cdc.gov/vaccines/hcp/acip-recs/index.html. Providers should be aware that changes in recommendations for specific vaccines can occur between annual updates to the childhood/adolescent immunization schedules.

  13. Efficacy of screening immune system function in at-risk newborns.

    Science.gov (United States)

    Pavlovski, Christopher J

    2014-01-01

    This paper explores the introduction of a screening test to highlight impaired immune system status for newborn infants and its efficacy as a preventative clinical measure. Moreover, it is suggested that screening of the infantile immune system has the potential to highlight susceptibility to a range of infant and childhood diseases, bestowing an opportunity to introduce early intervention to reduce the incidence of these diseases. Development of the neonatal immune system is an important health issue, implicated in many childhood problems such as allergies, infection, and autoimmunity. The neonate has a limited immune system and ability to combat bacteria. Depleted levels of the tripeptide reduced glutathione (GSH) have been linked to numerous conditions and its intracellular level is acknowledged as an indicator of immune system function. Introduction of an immune system screening programme for infants is formally reviewed and assessed. Several benefits are reported in the treatment of impaired immune systems, a trial screening programme is proposed for at-risk infants to gather further evidence as to its efficacy. Infants at risk of impaired immune system function include cystic fibrosis, premature infants, and low birth weight infants. The interventions include breastfeeding, milk banks, and appropriate formula to support the immune system.

    Erazo Torricelli, Ricardo

    2013-01-01

    Chronic ataxias are an heterogeneous group of disorders that affect the child at different ages. Thus, the congenital forms, generally non progressive are observed from first months of life and are expressed by hypotonia and motor delay long before the ataxia became evident. The cerebral magnetic resonance images (MRI) may be diagnostic in some pictures like Joubert syndrome. The group of progressive hereditary ataxias, usually begin after the infant period. The clinical signs are gait instability and ocular apraxia that can be associated with oculocutaneous telangiectasias (ataxia-telangiesctasia) or with sensory neuropathy (Friedreich ataxia). In this review are briefly described congenital ataxias and in more detailed form the progressive hereditary ataxias autosomal recessive, autosomal dominants and mitochondrials. The importance of genetic study is emphasized, because it is the key to obtain the diagnosis in the majority of these diseases. Although now there are no treatments for the majority of progressive hereditary ataxias, some they have like Refsum disease, vitamine E deficiency, Coenzyme Q10 deficiency and others, thus the diagnosis in these cases is even more important. At present the diagnosis of childhood hereditary ataxia not yet treatable is fundamental to obtain suitable handling, determine a precise outcome and to give to the family an opportune genetic counseling.

    Sledding is only rarely thought of as a potentially dangerous childhood activity. However, serious injuries and occasional deaths do occur. A review of patients 18 years old and younger admitted to a pediatric trauma center following a sledding accident from 1991 to 1997 was conducted. By design this study was expected to identify the most seriously injured patients. Twenty-five patients were identified, all but four younger than 13. Seventeen were boys. The mechanisms of injury were: collision with stationary object, 15; sled-sled collision, 1; struck by sled, 2; going off jump, 3; foot caught under sled or on ground, 3; fall off sled being towed by snowmobile, 1. The average pediatric trauma score was 10.5, and the average injury severity score 10.6. There were no deaths. The injuries were: head, 11; long bone/extremity, all lower, 10; abdomen, 5; chest, 1; facial, 2; spinal, 1. Five patients sustained multiple injuries. A surprisingly high number, 5, had pre-existing neurological conditions that could have played a contributory role in the accident. Sledding is predominantly an activity of children, and occasional serious injuries occur. Most are preventable. Obeying the simple caveat that sledding should only be done in clear areas away from stationary objects would eliminate the great majority of serious injuries.

  18. Completed suicide in childhood.

    Science.gov (United States)

    Dervic, Kanita; Brent, David A; Oquendo, Maria A

    2008-06-01

    Suicide in children and young adolescents up to 14 years of age has increased in many countries, warranting research and clinical awareness. International reported suicide rates per 100,000 in this young population vary between 3.1 and 0 (mean rate worldwide, approximately 0.6/100.000; male-female ratio, 2:1). Suicide occurs only in vulnerable children; this vulnerability begins with parental mood disorder and impulsive aggression, and family history of suicide. Childhood affective and disruptive disorders and abuse are the most often reported psychiatric risk factors. Suicide becomes increasingly common after puberty, most probably because of pubertal onset of depression and substance abuse, which substantially aggravate suicide risk. Biologic findings are scarce; however, serotonergic dysfunction is assumed. The most common precipitants are school and family problems and may include actual/anticipated transitions in these environments. Suicides in children and young adolescents up to 14 years of age often follow a brief period of stress. Cognitive immaturity/misjudgment, age-related impulsivity, and availability of suicide methods play an important role. Psychologic autopsy studies that focus on suicides in this age group are needed.

    2013-01-01

    Alternating hemiplegia of childhood (AHC) is a very rare disease characterized by recurrent attacks of loss of muscular tone resulting in hypomobility of one side of the body. The etiology of the disease due to ATP1A3 gene mutations in the majority of patients. Few familial cases have been described. AHC has an onset in the first few months of life. Hemiplegic episodes are often accompanied by other paroxysmal manifestations, such as lateral eyes and head deviation toward the hemiplegic side and a very peculiar monocular nystagmus. As the attack progresses, hemiplegia can shift to the other side of the body. Sometimes the attack can provoke bilateral paralysis, and these patients may have severe clinical impairment, with difficulty in swallowing and breathing. Hemiplegic attacks may be triggered by different stimuli, like bath in warm water, motor activity, or emotion. The frequency of attacks is high, usually several in a month or in a week. The duration is variable from a few minutes to several hours or even days. Sleep can stop the attack. Movement disorders such as dystonia and abnormal movements are frequent. Cognitive delay of variable degree is a common feature. Epilepsy has been reported in 50% of the cases, but seizure onset is usually during the third or fourth year of life. Many drugs have been used in AHC with very few results. Flunarizine has the most supportive anecdotal evidence regarding efficacy.

    2013-04-01

    In endemic regions of brucellosis, childhood brucellosis includes up to one-third of all cases of human brucellosis. The main source of infection in children is consumption of unpasteurized dairy products and traditional local foods containing dairy products. The older boys are more involved in animal care. Boys are more commonly infected than girls. Common symptoms and signs include fever, arthralgia, sweating, peripheral arthritis and splenomegaly. Peripheral arthritis especially monoarthritis is more common and the most commonly affected joints are hip and knee. All organs may involve during the course of the disease. Isolation of Brucella spp. from the blood, bone marrow or other tissue fluids is the hallmark of diagnosis. Serologic tests are the main tools of diagnosis of brucellosis in endemic regions. Standard agglutination test (SAT) with titers > 1:160 and the 2-mercaptoethanol (2ME) test ≥ 1:80 are suggestive of active infection. Children older than 8 years should be treated with doxycycline for 45 days or 8 weeks plus gentamicin for 7 or 5 days respectively or doxycycline for 45 days and streptomycin for 14 days. Also doxycycline plus rifampin or cotrimoxazole plus rifampin for 45 days may be alternative regimens. Cotrimoxazole plus rifampin for six weeks is the regimen of choice for the treatment of patients younger than 8 years old. Gentamicin for 5 days plus cotrimoxazole for six weeks may be a suitable alternative regimen. The article presented few of the patents associated with Brucellosis.

    2016-03-01

    Several topics on childhood asthma were addressed in the Paediatric Clinical Year in Review session at the 2015 European Respiratory Society International Congress. With regard to the relationship between lower respiratory tract infections and asthma, it emerges that is the number of respiratory episodes in the first years of life, but not the particular viral trigger, to be associated with later asthma development. Understanding which characteristics of individual patients are associated with an increased risk for asthma exacerbation is a critical step to implement strategies preventing these seasonal events. Recent data suggest the possibility that exhaled volatile organic compounds may qualify as biomarkers in detecting early signs of asthma. Adding information of exhaled volatile organic compounds and expression of inflammation genes to a clinical tool significantly improves asthma prediction in preschool wheezy children. Personal communication with children and adolescents is likely more important than the tools actually used for monitoring asthma. Systemic corticosteroids do not affect the long-term prognosis in children with first viral-induced wheezing episode and should be used cautiously during acute episodes. Finally, stress and a polymorphism upstream of a specific gene are both associated with reduced bronchodilator response in children with asthma.

  6. Epidemiology of childhood food allergy.

    Dyer, Ashley A; Gupta, Ruchi

    2013-06-01

    Food allergy is a public health problem that affects nearly 6 million children in the United States. The extent to which children, families, and communities live with food allergies varies as much as the range of clinical symptoms associated with the disease itself. Food allergy is defined as the reproducible adverse event that elicits a pathologic immunoglobulin E (IgE)-mediated or non-IgE-mediated reaction. Once an allergic child ingests a specific food allergen, the reaction can result in clinical symptoms ranging from mild hives to life-threatening anaphylaxis.Not surprisingly, food allergies have been shown to limit social interactions and impair children's quality of life due to the ubiquity of food where children live, learn, and play. To ensure the safety of our children, the development of sound policy, clinical practice, and health programs must be informed by current research characterizing childhood food allergy at the population level. To set the stage for understanding the current evidence base, this article reviews: 1) epidemiology of childhood food allergy; 2) severity of symptoms; 3) geographic distribution of childhood food allergy; 4) tolerance; 5) economic impact of childhood food allergy; and 6) future directions in childhood food allergy epidemiological research.

  7. Inertia and Decision Making.

    Science.gov (United States)

    Alós-Ferrer, Carlos; Hügelschäfer, Sabine; Li, Jiahui

    2016-01-01

    Decision inertia is the tendency to repeat previous choices independently of the outcome, which can give rise to perseveration in suboptimal choices. We investigate this tendency in probability-updating tasks. Study 1 shows that, whenever decision inertia conflicts with normatively optimal behavior (Bayesian updating), error rates are larger and decisions are slower. This is consistent with a dual-process view of decision inertia as an automatic process conflicting with a more rational, controlled one. We find evidence of decision inertia in both required and autonomous decisions, but the effect of inertia is more clear in the latter. Study 2 considers more complex decision situations where further conflict arises due to reinforcement processes. We find the same effects of decision inertia when reinforcement is aligned with Bayesian updating, but if the two latter processes conflict, the effects are limited to autonomous choices. Additionally, both studies show that the tendency to rely on decision inertia is positively associated with preference for consistency.

    The objective was to determine the demographic characteristics, the clinical features, the immuno-histological findings and response to treatment of childhood linear IgA bullous dermatosis (LABD) in Tunisia. We collected all the cases of auto-immune bullous diseases of childhood, diagnosed from January 1987 to December 2006. Based on clinical, histological, and immunofluorescent features, we identified 25 cases of LABD. Sixteen male and nine female children with a mean age of 7.5 years were identified. Clinical manifestations were characterized by a vesiculo-bullous eruption in all cases associated with mucous membrane involvement in two cases. Dapsone was the main therapy in 19 cases, associated with systemic corticosteroids in eight cases. Exclusive antibiotic therapy was successful in five cases. Sixteen of those patients had resolution of disease after a mean period of 15 months and eight patients had severe clinical presentation and required a prolonged follow-up. Childhood LABD is the most frequent bullous dermatosis in Tunisia. The majority of our patients responded rapidly to dapsone treatment and were stabilized for long time. Our cases were characterized by a minimal mucosal involvement and favorable outcome. Treatment with antibiotherapy was interesting. Erythromycin and oxacillin may be considered as an alternative therapy.

  12. Automation: Decision Aid or Decision Maker?

    Skitka, Linda J.

    1998-01-01

    This study clarified that automation bias is something unique to automated decision making contexts, and is not the result of a general tendency toward complacency. By comparing performance on exactly the same events on the same tasks with and without an automated decision aid, we were able to determine that at least the omission error part of automation bias is due to the unique context created by having an automated decision aid, and is not a phenomena that would occur even if people were not in an automated context. However, this study also revealed that having an automated decision aid did lead to modestly improved performance across all non-error events. Participants in the non- automated condition responded with 83.68% accuracy, whereas participants in the automated condition responded with 88.67% accuracy, across all events. Automated decision aids clearly led to better overall performance when they were accurate. People performed almost exactly at the level of reliability as the automation (which across events was 88% reliable). However, also clear, is that the presence of less than 100% accurate automated decision aids creates a context in which new kinds of errors in decision making can occur. Participants in the non-automated condition responded with 97% accuracy on the six "error" events, whereas participants in the automated condition had only a 65% accuracy rate when confronted with those same six events. In short, the presence of an AMA can lead to vigilance decrements that can lead to errors in decision making.

  13. Brucellosis in childhood.

    1975-03-01

    Brucellosis has always been an unusual disease in children and, concomitant with the control of the disease in domestic animals, reports have become sparse. The pediatrician, therefore, may not be aware of the protean clinical manifestations of childhood brucellosis. In 1973, nine cases occurred during a three-month period in El Paso, Texas. All cases were marked by spiking fevers and lethargy of four days to four weeks in duration. Tender hepatomegaly or splenomegaly was striking in seven patients. Other characteristics included epistaxis, arthralgia, myalgia, and weight loss. Leukopenia and leukemoid reaction were found in five patients. All of the patients tested had elevated liver enzymes. Febrile agglutinins were invaluable in screening for an early clue to diagnosis. When Brucella abortus antigen agglutinated serum from patients with a positive screen in dilutions greater than 1:320, a presumptive diagnosis of brucellosis was made. Brucella was isolated from the blood or bone marrow in seven patients and the time of incubation proved crucial for successful recovery. Bacterial blood cultures are usually discarded at ten days of age, as were cultures from the only two patients from whom the organism was not recovered. All of the cultures incubated for 12 to 15 days grew B. melitensis, an unusual causative species in the United States. However, several patients admitted eating cheese from the State of Chihuahua, Mexico, made from unpasteurized goat's milk, the presumed source of the infection. Within one to three days, all patients responded dramatically to antibiotics; tetracycline was given orally for 21 days and streptomycin intramuscularly for 14 days. Pediatricians caring for patients in areas where consumption of unpasteurized milk products is likely would do well to consider brucellosis in a child with obscure fever or toxic hepatosplenomegaly.

  14. Probiotic Use in Childhood

    2014-08-01

    Full Text Available Probiotics are live microorganisms that produce a benefit to host by improving microbial balance in the gut, when provided in adequate amounts from food and supplements. Probiotics, taken with foods or food supplements are bacteria or yeasts. They act by reducing the number of pathogens and harmful bacteria, by changing microbial metabolism and by improving the immune system. They are in capsule, tablet, cachet or powdered form. In randomised controlled trials with probiotics, the prevention of acute infectious diarrhea in healthy infants and children had shown moderate benefits. The effect of probiotics in acute viral diarrhea is well studied. More research is needed to determine the effect of probiotics in antibiotic associated diarrhea, irritable bowel syndrome, ulcerative colitis, Crohn’s disease, helicobacter pylori infection, constipation and extraintestinal infections. There are positive results with probiotics in atopic diseases and preventing necrotising enterocolitis in premature infants. Studies continue for the effectiveness of the probiotics in various clinical conditions in children.

    Survivors of war trauma or childhood maltreatment are at increased risk for trauma-spectrum disorders such as post-traumatic stress disorder (PTSD). In addition, traumatic stress has been associated with alterations in the neuroendocrine and the immune system, enhancing the risk for physical diseases. Traumatic experiences might even affect psychological as well as biological parameters in the next generation, i.e. traumatic stress might have transgenerational effects. This article outlines how epigenetic processes, which represent a pivotal biological mechanism for dynamic adaptation to environmental challenges, might contribute to the explanation of the long-lasting and transgenerational effects of trauma. In particular, epigenetic alterations in genes regulating the hypothalamus-pituitary-adrenal axis as well as the immune system have been observed in survivors of childhood and adult trauma. These changes could result in enduring alterations of the stress response as well as the physical health risk. Furthermore, the effects of parental trauma could be transmitted to the next generation by parental distress and the pre- and postnatal environment, as well as by epigenetic marks transmitted via the germline. While epigenetic research has a high potential of advancing our understanding of the consequences of trauma, the findings have to be interpreted with caution, as epigenetics only represent one piece of a complex puzzle of interacting biological and environmental factors.

  16. Role of food allergy in childhood atopic dermatitis.

    Science.gov (United States)

    Campbell, Dianne E

    2012-12-01

    The interplay between atopic dermatitis (AD) and food allergy is complex and subject to significant misconceptions both by the general public and the medical community. Childhood AD is a very prevalent disorder. In its moderate and severe forms, AD is a challenging disorder to manage from the perspective of the child, parent and treating doctor. As AD is one of the disease manifestations of atopy, it is unsurprising that many children with AD also have a coexisting IgE-mediated food allergy. It is a common misconception that food allergy is causal in the setting of AD. However, in a proportion of sufferers, food allergy does play a role in triggering or exacerbating pre-existing AD by immune-mediated mechanisms and potentially by non-immune mechanisms. It is, therefore, important to differentiate causality, co-existent disease and disease modifiers in this context. This paper seeks to clarify the role of food allergy in childhood AD, and to outline a rational framework for the diagnosis and approach to food allergy in the context of the management of a child with problematic AD.

    This study integrates two important developments, the concept of health lifestyles (which has focused on adults and adolescents) and the increased attention to early childhood. We introduce the concept of children's health lifestyles, identifying differences from adult health lifestyles and articulating intergenerational transmission and socialization processes shaping children's health lifestyles. Using the nationally representative Early Childhood Longitudinal Study-Birth Cohort (2001-2007; N ≈ 6,150), latent class analyses identify predominant health lifestyles among U.S. preschoolers. Five distinct empirical patterns representing health lifestyles emerge, two capturing low and medium levels of overall risk across domains and three capturing domain-specific risks. Social background predicts children's health lifestyles, but lower household resources often explain these relationships. Across kindergarten measures of cognition, behavior, and health, preschool health lifestyles predict children's development even after controlling for social disadvantage and concurrent household resources. Further research on health lifestyles throughout childhood is warranted.

    The aim of this study is to describe the childhood vasculitis hospital burden in Spain (1997-2011), considering type of disease, hospitalization rates and time trends. Data were obtained from the National Discharges Basic Minimum Data Set (National Patient Data Base). Inpatient events of children younger than 15 years of age were analyzed. Principal diagnosis of vasculitis were selected according Ninth Revision of the International Classification of Diseases: Takayasu arteritis, Polyarteritis nodosa, Kawasaki disease, Wegener`s granulomatosis, Churg-Strauss syndrome, and Henoch-Schönlein purpura. A total of 14518 children hospitalizations related to vasculitis were identified in Spain from 1997 to 2011. The average hospitalization rate for children was 13.33±1.71 per 100,000. Henoch-Schönlein purpura and Kawasaki disease were the most common type of vasculitis, hospitalization rates were 11.00 and 3.97 per 100,000 children, respectively. Other vasculitis hospitalizations are much rare in childhood. Average length of stay was 6.04 days and estimated cost per inpatient hospital care was 2,847€. Hospital case fatality rate was 0.05% for overall vasculitis. In conclusion, epidemiological data of childhood vasculitis are useful both to health decision-making and to identify research priorities.

    Food allergy is a growing public health concern in the United States that affects an estimated 8% of children. Food allergy is defined as an adverse health effect arising from a specific immune response that occurs reproducibly on exposure to a specific food. Nearly 40% of children with food allergy have a history of severe reactions that if not treated immediately with proper medication can lead to hospitalization or even death. The National Institute of Allergy and Infectious Diseases (NIAID) convened an expert panel in 2010 to develop guidelines outlining evidence-based practices in diagnosing and managing food allergy. The purpose of this review is to aid clinicians in translating the NIAID guidelines into primary care practice and includes the following content domains: (1) the definition and mechanism of childhood food allergy, (2) differences between food allergy and food intolerance, (3) the epidemiology of childhood food allergy in the United States, (4) best practices derived from the NIAID guidelines focused on primary care clinicians' management of childhood food allergy, (5) emerging food allergy treatments, and (6) future directions in food allergy research and practice. Articles focused on childhood food allergy were considered for inclusion in this review. Studies were restricted to the English language and to those published within the past 40 years. A cross-listed combination of the following words, phrases, and MeSH terms was searched in PubMed and Google Scholar to identify relevant articles: food allergy, food hypersensitivity, child, pediatric, prevalence, and epidemiology. Additional sources were identified through the bibliographies of the retrieved articles.

  1. Impact of early life exposures to geohelminth infections on the development of vaccine immunity, allergic sensitization, and allergic inflammatory diseases in children living in tropical Ecuador: the ECUAVIDA birth cohort study

    2011-06-01

    Full Text Available Abstract Background Geohelminth infections are highly prevalent infectious diseases of childhood in many regions of the Tropics, and are associated with significant morbidity especially among pre-school and school-age children. There is growing concern that geohelminth infections, particularly exposures occurring during early life in utero through maternal infections or during infancy, may affect vaccine immunogenicity in populations among whom these infections are endemic. Further, the low prevalence of allergic disease in the rural Tropics has been attributed to the immune modulatory effects of these infections and there is concern that widespread use of anthelmintic treatment in high-risk groups may be associated with an increase in the prevalence of allergic diseases. Because the most widely used vaccines are administered during the first year of life and the antecedents of allergic disease are considered to occur in early childhood, the present study has been designed to investigate the impact of early exposures to geohelminths on the development of protective immunity to vaccines, allergic sensitization, and allergic disease. Methods/Design A cohort of 2,403 neonates followed up to 8 years of age. Primary exposures are infections with geohelminth parasites during the last trimester of pregnancy and the first 2 years of life. Primary study outcomes are the development of protective immunity to common childhood vaccines (i.e. rotavirus, Haemophilus influenzae type B, Hepatitis B, tetanus toxoid, and oral poliovirus type 3 during the first 5 years of life, the development of eczema by 3 years of age, the development of allergen skin test reactivity at 5 years of age, and the development of asthma at 5 and 8 years of age. Potential immunological mechanisms by which geohelminth infections may affect the study outcomes will be investigated also. Discussion The study will provide information on the potential effects of early exposures to

    Childhood serum sickness is a rare allergic disease that follows the administration of a foreign antigenic material, most commonly caused by injecting a protein or haptenic drug. The disease is a type III hypersensitivity reaction mediated by deposits of circulating immune complexes in small vessels, which leads to complement activation and subsequent inflammation. The clinical features are fever, cutaneous eruptions, lymphadenopathy, arthralgias, albuminuria, and nephritis. Serum sickness is an acute self-limited disease. We report a 3-year-old child who presented with fever and a rash; an invasive bacterial infection was strongly suspected. He was therefore given penicillin and gentamicin and responded well. At day 4 after admission, he developed a serum sickness reaction and showed symptoms of arthralgias, generalized edema, purpura, and gross hematuria. The white blood cell count was 12 190/mm3 with 7% eosinophils. Urinalysis revealed red blood cell above 100 per high power field, white blood cell 10 to 15 per high power field, and proteinuria. The antibiotics were discontinued and hydrocortisone (20 mg/kg/d), diphenhydramine HCl (4 mg/kg/d), aspirin (66 mg/kg/d) was administered, plus 1 dose of epinephrine (0.01 mL/kg) administered intramuscularly. On day 7, the 3rd day after withholding antibiotics, his condition dramatically improved. The clinical symptoms resolved progressively and his urinalysis returned to normal.

    Full Text Available Vitamin D is an essential component of bone and mineral metabolism; its deficiency causes growth retardation and skeletal deformities in children and osteomalacia and osteoporosis in adults. Hypovi­ taminosis D (vitamin D insufficiency or deficiency is observed not only in adults but also in infants, children, and adolescents. Previous studies suggest that sufficient serum vitamin D levels should be maintained in order to enhance normal calcification of the growth plate and bone mineralization. Moreover, emerging evidence supports an association between 25­hydroxyvitamin D (25[OH]D levels and immune function, respiratory diseases, obesity, metabolic syndrome, insulin resistance, infection, allergy, cancers, and cardiovascular diseases in pediatric and adolescent populations. The risk factors for vitamin D insufficiency or deficiency in the pediatric population are season (winter, insufficient time spent outdoors, ethnicity (non­white, older age, more advanced stage of puberty, obesity, low milk consumption, low socioeconomic status, and female gender. It is recommended that all infants, children, and adolescents have a minimum daily intake of 400 IU (10 μg of vitamin D. Since the vitamin D status of the newborn is highly related to maternal vitamin D levels, optimal vitamin D levels in the mother during pregnancy should be maintained. In conclusion, given the important role of vitamin D in childhood health, more time spent in outdoor activity (for sunlight exposure and vitamin D supplementation may be necessary for optimal health in infants, children, and adolescents.

  4. Simultaneous immunization against tuberculosis.

    Full Text Available BACKGROUND: BCG, the only licensed vaccine against tuberculosis, provides some protection against disseminated disease in infants but has little effect on prevention of adult pulmonary disease. Newer parenteral immunization prime boost regimes may provide improved protection in experimental animal models but are unproven in man so that there remains a need for new and improved immunization strategies. METHODS AND FINDINGS: Mice were immunized parenterally, intranasally or simultaneously by both routes with BCG or recombinant mycobacterial antigens plus appropriate adjuvants. They were challenged with Mycobacterium tuberculosis (Mtb and the kinetics of Mtb growth in the lungs measured. We show that simultaneous immunization (SIM of mice by the intranasal and parenteral routes is highly effective in increasing protection over parenteral BCG administration alone. Intranasal immunization induces local pulmonary immunity capable of inhibiting the growth of Mtb in the early phase (the first week of infection, while parenteral immunization has a later effect on Mtb growth. Importantly, these two effects are additive and do not depend on priming and boosting the immune response. The best SIM regimes reduce lung Mtb load by up to 2 logs more than BCG given by either route alone. CONCLUSIONS: These data establish SIM as a novel and highly effective immunization strategy for Mtb that could be carried out at a single clinic visit. The efficacy of SIM does not depend on priming and boosting an immune response, but SIM is complementary to prime boost strategies and might be combined with them.

    Otitis media is a common disease in childhood. In adults, the disease is relatively rare, but more frequently associated with complications. Possible reasons for this discrepancy are age-related differences in pathogen exposure, anatomy of the Eustachian tube and immune system. The objective of this study was to analyze the relationship between age and the mucosal immune system in the middle ear. It is hypothesized that genes involved in the middle ear immune system will change with age. A comprehensive assessment of these genetic differences using the techniques of complementary DNA has not been performed. Complementary DNA microarray technology was used to identify immune-related genes differentially expressed between the normal middle ear mucosa of young (10 days old) and adult rats (80 days old). Data were analyzed using tools of bioinformatics. A total of 260 age-related genes were identified, of which 51 genes were involved in the middle ear mucosal immune system. Genes related to the innate immune system, including alpha-defensin, calcium-binding proteins S100A9 and S100A8, were upregulated in young rats, whereas genes related to the adaptive immune system, including CD3 molecules, zeta-chain T-cell receptor-associated protein kinase and linker of activated T-cells, were upregulated in the adult. This study concludes that the normal middle ear immune system changes with age. Genes related to the innate immune system are upregulated in young rats, whereas genes related to the adaptive immune system are upregulated in adults.

    A retrospective chart review was conducted to detect patients with sarcoidosis seen by pediatric rheumatology service from the period of 1992 to 2013 at Children's hospital of New Orleans. Twenty-seven patients were identified. The average duration of symptoms before diagnosis was 5 (range 1-120) months. Five patients had onset before the age of 5 years and were diagnosed with early-onset sarcoidosis. The most common manifestations at presentation were constitutional symptoms (62 %) followed by ocular (38 %). During the course of illness, 19/27 (70 %) had multiorgan involvement. Common manifestations included uveitis/iritis (77 %), fever (50 %), hilar adenopathy (42 %), arthritis (31 %), peripheral lympadenopathy (31 %), hepatosplenomegaly (31 %), parenchymal lung disease (27 %), and skin rash (19 %). Unusual manifestations included granulomatous bone marrow disease (3 cases), hypertension (2), abdominal aortic aneurysm (large vessel vasculitis; 1), granulomatous hepatitis (1), nephrocalcinosis (1), membranous nephropathy (1), refractory granulomatous interstitial nephritis with recurrence in transplanted kidney (1), CNS involvement (2), parotid gland enlargement (1), and sensorineural hearing loss (1). Biopsy specimen was obtained in 21/27 (77 %) patients, and demonstration of noncaseating granuloma associated with negative stains for mycobacteria and fungi was seen in 18 patients. Elevated angiotensin-converting enzyme level was seen in 74 % of patients. Treatment with oral prednisone was initiated in symptomatic patients with significant clinical improvement. Low-dose methotrexate (MTX) 10-15 mg/m(2)/week orally, as steroid-sparing agent, was administered in 14 patients. Other immunomodulators included cyclophosphamide (2 patients), etanercept (2), infliximab (2), mycophenolate mofetil (1), and tacrolimus (1). Childhood sarcoidosis is prevalent in Louisiana. Most of the affected children present with a multisystem disease associated with

    Full Text Available The knowledge, attitude and practice of mothers toward childhood immunization was surveyed in 2 neighborhoods in greater Bombay, India. The areas were a slum of 75,000 called Malavani, and a nearby area called Kharodi. Measles and triple (DPT or DPV vaccines were available at local health centers, 1.5 km away at the most; oral polio vaccines were given by field workers to the Malavani community to children in their homes, but only in the center for those in Kharodi. BCG tuberculosis vaccinations were available to all, but from a center 5 km away. Malavani mothers had significantly better knowledge of triple and measles vaccines, but knowledge about BCG was similar in the 2 groups. Slightly more women from Kharodi expressed negative attitudes toward immunization. Coverage of children, established from clinic records, was significantly better in the Malavani area: 91% vs. 58% for polio; 71% vs 61% for BCG (n.s.; 85% vs. 55% for triple vaccine; and 21% vs 1% for measles. Evidently, visitation by field teams with polio vaccinations affected mothers′ knowledge and practice for other immunizations available only at the center.

    2015-01-01

    Full Text Available The article analyzes the nature, types, characteristics of the phenomenon of childhood as a social phenomenon of our time. The author notes the complexity of the definition of “childhood” and its different interpretations. The author also notes that social “construction” considers not childhood itself in its entirety but childhood through the "prism of adulthood". Childhood is often seen as something natural through which goes everyone and something that everybody must have as a result of education and development. At the same time, is lost the understanding of childhood as a valuable phenomenon in itself. The author draws attention to different ways of studying childhood in psychology, literature and history and correlates concepts of childhood in psychology, history and culturology. The author considers the childhood concept by Philippe Aries in correlation with the image of childhood in the novels by Charles Dickens. This choice is determined by specific periodizations of childhood in history and culture what makes the specific development of the world of childhood dependent on the evolution of the world of grown-ups and its culture.

    2011-01-01

    Adaptive immunity, involving distinctive antibody- and cell-mediated responses to specific antigens based on "memory" of previous exposure, is a hallmark of higher vertebrates. It has been argued that adaptive immunity arose rapidly, as articulated in the "big bang theory" surrounding its origins, which stresses the importance of coincident whole-genome duplications. Through a close examination of the key molecules and molecular processes underpinning adaptive immunity, this review suggests a less-extreme model, in which adaptive immunity emerged as part of longer evolutionary journey. Clearly, whole-genome duplications provided additional raw genetic materials that were vital to the emergence of adaptive immunity, but a variety of other genetic events were also required to generate some of the key molecules, whereas others were preexisting and simply co-opted into adaptive immunity.

    2017-01-01

    The human immune system is highly variable between individuals but relatively stable over time within a given person. Recent conceptual and technological advances have enabled systems immunology analyses, which reveal the composition of immune cells and proteins in populations of healthy individuals. The range of variation and some specific influences that shape an individual's immune system is now becoming clearer. Human immune systems vary as a consequence of heritable and non-heritable influences, but symbiotic and pathogenic microbes and other non-heritable influences explain most of this variation. Understanding when and how such influences shape the human immune system is key for defining metrics of immunological health and understanding the risk of immune-mediated and infectious diseases.

    Full Text Available Insect innate immunity is both a model for vertebrate immunity as well as a key system that impactsmedically important pathogens that are transmitted by insects. Recent developments in proteomics andprotein identification techniques combined with the completion of genome sequences for Anophelesgambiae and Drosophila melanogaster provided the tools for examining insect immunity at a new level ofmolecular detail. Application of proteomics to insect immunity resulted in predictions of new roles inimmunity for proteins already known in other contexts (e.g. ferritin, transferrin, Chi-lectins and helped totarget specific members of multi-gene families that respond to different pathogens (e.g. serine proteases,thioester proteins. In addition, proteomics studies verify that post-translational modifications play a keyrole in insect immunity since many of the identified proteins are modified in some way. These studiescomplement recent work on insect transcriptomes and provide new directions for further investigation ofinnate immunity.

    2013-12-01

    Personality disorders manifest themselves in stable deviations of personality traits that especially arise in negative interactions with others. Those typical dysfunctional interactions can be observed particularly in dissocial and antisocial personality disorders: adults with severe forms of personality disorders often showed specific symptoms in childhood and adolescence. Clinical researchers therefore demand a respective diagnosis of childhood and adolescent psychopathy. There is an extensive body of research on dissocial and borderline personality disorders in children and adolescents. To date the severe form of dissocial personality disorders, psychopathy, cannot be specifically classified. The transfer of this diagnosis to childhood and adolescence is crucial: based on the assumption of persistence and the risk of stigmatisation many clinicians refuse to diagnose psychopathy at a young age. On the other hand there are positive treatment outcomes that aim at symptom reduction from a very early age. The specification of dissocial personality disorders in childhood and adolescence may encourage the development of new treatments and the de-stigmatisation as well as qualify the dogged assumption of persistence of personality disorders.

    Acute promyelocytic leukemia (APL) comprises approximately 5-10% of childhood acute myeloid leukemia (AML) cases in the US. While variation in this percentage among other populations was noted previously, global patterns of childhood APL have not been thoroughly characterized. In this comprehensive review of childhood APL, we examined its geographic pattern and the potential contribution of environmental factors to observed variation. In 142 studies (spanning >60 countries) identified, variation was apparent-de novo APL represented from 2% (Switzerland) to >50% (Nicaragua) of childhood AML in different geographic regions. Because a limited number of previous studies addressed specific environmental exposures that potentially underlie childhood APL development, we gathered 28 childhood cases of therapy-related APL, which exemplified associations between prior exposures to chemotherapeutic drugs/radiation and APL diagnosis. Future population-based studies examining childhood APL patterns and the potential association with specific environmental exposures and other risk factors are needed.

    Full Text Available People and organizations make better or get wrong as consequence of making decisions. Sometimes making decisions is just a trial and error process. Some others, decisions are good and the results profitable with a few of mistakes, most of the time because it’s considered the experience and the control of a specific field or the good intention of who makes them. Actually, all kinds of decisions bring learning. What is important is the intention, the attitude and the values considered in this process. People from different scenes face many facts and circumstances—almost always out of control—that affect the making decisions process. There is not a unique way to make decisions for all companies in many settings. The person who makes a decision should identify the problem, to solve it later using alternatives and solutions. Even though, follow all the steps it’s not easy as it seems. Looking back the conditions related to the decisions, we can mention the followings: uncertainty, risk and certainty. When people identify circumstances and facts, as well as its effects in a possible situation, they will make decisions with certainty. As long as the information decreases and it becomes ambiguous the risk becomes an important factor in the making decisions process because they are connected to probable objectives (clear or subjective (opinion judgment or intuition. To finish, uncertainty, involves people that make a decision with no or little information about circumstances or criteria with basis

    2015-10-01

    Children (0-18 years) with maltreatment histories are vulnerable to experiencing difficulties across multiple domains of functioning, including educational outcomes that encompass not only academic achievement but also mental well-being. The current literature review adopted Slade and Wissow's model to examine (1) the link between childhood maltreatment and academic achievement, (2) the link between childhood maltreatment and mental health outcomes (i.e., emotional and behavioral difficulties), and (3) the bidirectional relationship between childhood academic achievement and mental health. In addition, we reviewed variables that might influence or help explain the link between childhood maltreatment and educational outcomes, drawing on developmental perspectives and Bronfenbrenner's ecological model. Finally, whenever possible, we presented findings specific to maltreated children in out-of-home care to highlight the unique challenges experienced by this population. Results indicated that children with maltreatment histories often experience impairments in both their academic performance (e.g., special education, grade retention, lower grades) and mental well-being (e.g., anxiety, low mood, aggression, social skills deficits, poor interpersonal relationships). These impairments appeared to be particularly pronounced among maltreated children in out-of-home care. Findings, albeit sparse, also indicated that mental health difficulties are negatively associated with children's academic achievement and, similarly, that academic achievement deficits are linked with mental health problems. The link between childhood maltreatment and educational outcomes may be partly explained through the disruption of key developmental processes in children, such as attachment, emotion regulation, and sense of agency. As well, maltreatment characteristics and the functioning of various systems in which children are embedded (e.g., family, school, child welfare) can serve to positively

    2015-09-01

    Childhood Obesity is associated with a wide range of serious health complications and constitutes an increased risk of premature syndromes, including diabetes or heart diseases. Its treatment seems to be complicated. So, in order to help parents we have developed a system that will try to make easier the process of choosing foodstuff for overweight and obese children at the supermarket. To interact with the system, Near Field Communication mobile phones and tags are used. Those tags would have nutritional information such as energy or fat contain of each product. When the interaction takes place, the system will generate an alert determining if the product is adequate for the user diet or not. Decision will be influenced by specific prescript diets, which would have been previously generated by the system based on user profile parameters. At the same time the diet is established, the shopping list would be generated automatically. Therefore, the user could download and print both things at home easily by the PC application. The system also takes into account physical activity of the user. Children mobile phone includes an accelerometer that will detect and collect user activities in order to modify calorical requirements and, if necessary, to change physical activity too. In the future, it would be possible to extend this project system for adults, managing diets not just for obese and overweight, but also to diabetic or celiac people.

  18. Influence of socioeconomic status trajectories on innate immune responsiveness in children.

    Directory of Open Access Journals (Sweden)

    Meghan B Azad

    Full Text Available OBJECTIVES: Lower socioeconomic status (SES is consistently associated with poor health, yet little is known about the biological mechanisms underlying this inequality. In children, we examined the impact of early-life SES trajectories on the intensity of global innate immune activation, recognizing that excessive activation can be a precursor to inflammation and chronic disease. METHODS: Stimulated interleukin-6 production, a measure of immune responsiveness, was analyzed ex vivo for 267 Canadian schoolchildren from a 1995 birth cohort in Manitoba, Canada. Childhood SES trajectories were determined from parent-reported housing data using a longitudinal latent-class modeling technique. Multivariate regression was conducted with adjustment for potential confounders. RESULTS: SES was inversely associated with innate immune responsiveness (p=0.003, with persistently low-SES children exhibiting responses more than twice as intense as their high-SES counterparts. Despite initially lower SES, responses from children experiencing increasing SES trajectories throughout childhood were indistinguishable from high-SES children. Low-SES effects were strongest among overweight children (p<0.01. Independent of SES trajectories, immune responsiveness was increased in First Nations children (p<0.05 and urban children with atopic asthma (p<0.01. CONCLUSIONS: These results implicate differential immune activation in the association between SES and clinical outcomes, and broadly imply that SES interventions during childhood could limit or reverse the damaging biological effects of exposure to poverty during the preschool years.

    Full Text Available In 2000 the Organization of the United Nations established eight Millennium Development Goals (MDGs. The fourth objective, reducing child mortality, looks specifically for reducing two thirds of the mortality of children under five years old between 1990 and 2015. One of the specific indicators to measure progress towards this goal is the proportion of children under one year old immunized against measles.In 2001, the United Nations Development Program (UNDP estimated that over 60% of the population who lived in developing nations is far away or losing ground on achievement of the MDGs in reducing rates of infant mortality. This situation is compounded by the lack of progress in deepening the analysis of the issue, the lack of research and indicators to assess features timely coverage of care and health services.This article aims to contribute to the selection of the strategy which would improve health coverage in Misiones, using one of the tools of decision theory, the decision matrix.

    Adolescent vaccination coverage is very variable in European countries and data are scarce. The aim of this study was to assess immunization status and analyze potential variations according to sociodemographic variables in a youth clinic in Geneva, Switzerland. Immunization status was assessed retrospectively: Tetanus (number of doses or in absence of data tetanus antibodies) and measles as indicators of childhood coverage as well as hepatitis B and human papillomavirus. All new patients (N = 390) of Geneva University Hospital's youth clinic were included between January 2010 and June 2011. Vaccine coverage was low for all vaccines regardless of sex or origin. 89% of young people tested (mostly recent immigrants with no available data) had tetanus antibodies indicating adequate childhood immunization but hepatitis B and HPV coverage was low especially in recent immigrants. Systematic assessment allows better adolescent vaccine coverage and can improve safety by avoiding unnecessary dosis.

    2012-09-14

    WHO convened a meeting of around 30 experts to address the topic of aging and immunization in March 2011 in Geneva. The purpose of the meeting was to develop a global research agenda to eventually inform WHO policy recommendations regarding immunization beyond childhood and into old age. This issue is becoming more critical, since the population aged 60 and above will reach two billion people - three-quarters of whom will be in developing countries - in the next 40 years. The meeting reviewed current knowledge and gaps in information about: (1) the epidemiology of infectious diseases in the elderly in developed and developing countries and their contribution to disability in old age; (2) the deterioration of the immune system with age ("immune senescence") and possible ways to measure and counteract it; and (3) immunization approaches to maintain or improve health in older persons. These approaches include the concept of a "life-course vaccination" schedule to help sustain immunity to vaccine-preventable diseases beyond childhood and into old age; strategies to strengthen older persons' responses to vaccines (e.g., by adding adjuvants to vaccines, increasing vaccine dosage, and intradermal vaccine administration); and the possible development of new vaccines targeted specifically for older adults. Participants proposed priority research topics as well as strategies to facilitate and coordinate the research, including the establishment of networks of collaborators, with WHO playing a key coordinating role.

    2014-11-06

    Life-threatening fungal infections have risen sharply in recent years, owing to the advances and intensity of medical care that may blunt immunity in patients. This emerging crisis has created the growing need to clarify immune defense mechanisms against fungi with the ultimate goal of therapeutic intervention. We describe recent insights in understanding the mammalian immune defenses that are deployed against pathogenic fungi. We focus on adaptive immunity to the major medically important fungi and emphasize three elements that coordinate the response: (1) dendritic cells and subsets that are mobilized against fungi in various anatomical compartments; (2) fungal molecular patterns and their corresponding receptors that signal responses and shape the differentiation of T-cell subsets and B cells; and, ultimately (3) the effector and regulatory mechanisms that eliminate these invaders while constraining collateral damage to vital tissue. These insights create a foundation for the development of new, immune-based strategies for prevention or enhanced clearance of systemic fungal diseases.

  3. Behavioral Immunity in Insects

    2012-08-01

    Full Text Available Parasites can dramatically reduce the fitness of their hosts, and natural selection should favor defense mechanisms that can protect hosts against disease. Much work has focused on understanding genetic and physiological immunity against parasites, but hosts can also use behaviors to avoid infection, reduce parasite growth or alleviate disease symptoms. It is increasingly recognized that such behaviors are common in insects, providing strong protection against parasites and parasitoids. We review the current evidence for behavioral immunity in insects, present a framework for investigating such behavior, and emphasize that behavioral immunity may act through indirect rather than direct fitness benefits. We also discuss the implications for host-parasite co-evolution, local adaptation, and the evolution of non-behavioral physiological immune systems. Finally, we argue that the study of behavioral immunity in insects has much to offer for investigations in vertebrates, in which this topic has traditionally been studied.

    "Transplantation immunity in Cyclosporin era" is a special chapter in science under name transplantation immunity. Nowadays, practically all the organs can be grafted: kidney, heart, lung, liver, pancreas both as organ, and as islet cells, bone marrow from relative and unrelative donors. The broad spectrum of grafted organs gave one more surprising peculiarity of transplantation immunity: it operates with different strength after transplantation of various organs. If the decreasing gradient of transplantation immunity could be composed, then it appeared to be approximately in the following order: bone marrow - skin - kidney - heart - lung. The most complicated operating activity of transplantation immunity is occurring after bone marrow transplantation, especially from unrelative donor, because in bone marrow transplantation immunological process develops in both directions. Therefore now, bone marrow is the only organ (tissue), when the complete compatibility between donor and recipient is required after its transplantation; especially in cases with unrelative donors.

    2010-01-01

    The human immune system has numerous properties that make it ripe for exploitation in the computational domain, such as robustness and fault tolerance, and many different algorithms, collectively termed Artificial Immune Systems (AIS), have been inspired by it. Two generations of AIS are currently in use, with the first generation relying on simplified immune models and the second generation utilising interdisciplinary collaboration to develop a deeper understanding of the immune system and hence produce more complex models. Both generations of algorithms have been successfully applied to a variety of problems, including anomaly detection, pattern recognition, optimisation and robotics. In this chapter an overview of AIS is presented, its evolution is discussed, and it is shown that the diversification of the field is linked to the diversity of the immune system itself, leading to a number of algorithms as opposed to one archetypal system. Two case studies are also presented to help provide insight into the m...

    Vanha-Aho, Leena-Maija; Valanne, Susanna; Rämet, Mika

    2016-02-01

    Cytokines are a large and diverse group of small proteins that can affect many biological processes, but most commonly cytokines are known as mediators of the immune response. In the event of an infection, cytokines are produced in response to an immune stimulus, and they function as key regulators of the immune response. Cytokines come in many shapes and sizes, and although they vary greatly in structure, their functions have been well conserved in evolution. The immune signaling pathways that respond to cytokines are remarkably conserved from fly to man. Therefore, Drosophila melanogaster, provides an excellent platform for studying the biology and function of cytokines. In this review, we will describe the cytokines and cytokine-like molecules found in the fly and discuss their roles in host immunity.

    2014-10-01

    Narcolepsy with cataplexy is a severely disabling disorder very often arising in childhood. Data on neuropsychological impairment in children are scant. We administered standardized neuropsychological tests to 13 children with narcolepsy with cataplexy. Overall, our patients displayed multiple patterns of cognitive and behavioral dysfunction, and often academic failure (7 cases out of 13). All children had a normal full intelligence quotient (IQ), but 3 patients presented a significantly higher and 2 a significantly lower Verbal IQ compared to Performance IQ, respectively. Mean sleep latency was significantly correlated (P emotional symptoms and conduct problems prevailed. Childhood narcolepsy with cataplexy represents a risk factor for subtle and heterogeneous cognitive impairments potentially resulting in academic failure, despite the normal IQ. These children also have a certain psychopathological risk. All this seems to be at least partially detached from the direct effects of daytime sleepiness.

    Full Text Available Bipolar disorder is a chronic disorder in which irregular course of depressive, mania or mixed episodes or a complete recovery between episodes can be observed. The studies about the effects of traumatic events on bipolar disorder showed that they had significant and long-term effects on the symptoms of the disorder. Psychosocial stress might change the neurobiology of bipolar disorder over time. The studies revealed that the traumatic events could influence not only the onset of the disorder but also the course of the disorder and in these patients the rate of suicide attempt and comorbid substance abuse might increase. Bipolar patients who had childhood trauma had an earlier onset, higher number of episodes and comorbid disorders. In this review, the relationship between childhood trauma and bipolar disorder is reviewed. [Psikiyatride Guncel Yaklasimlar - Current Approaches in Psychiatry 2015; 7(2: 157-165

    The early childhood care is important not only for individual Greek children and families but also for Greek society at large. Furthermore, it needs to be secured that the burden of labour and the raising of child is not only a woman's duty. There is a broad recognition that a strategy for developing early childhood services and childcare to support mother's labour force participation is in the public interest and should be the primary scope of the national health and social care policy. The inadequate organization of the child welfare system has adverse effects on the well-being, and function of the family. Only the improvement of the expected protection can lead to social politics that will give a chance to mother and child to live in conditions fitting human value and dignity. Herein, we presented the regulations and services along with health care professionals that refer to the protection of child in Greece.

    Farmer, Kathleen; Dunn, David; Scott, Eric

    2010-06-01

    Recurrent headaches in children are most often migraines and are based in a genetic predisposition with a low headache threshold. As with any pain experience, there is a large emotional component associated with an attack of migraines that grows in amplitude as the headaches become more frequent and resistant to medicine, sleep, or other agents that used to work. Childhood headaches are especially complicated for 3 reasons: (1) the parents' fear (communicated to the child that serious medical pathology underlies the head pain), (2) the lack of evidence-based pharmacologic treatment, and (3) the belief that these headaches are largely psychological. This article addresses the mystery surrounding childhood headaches by delving into the influence of school, friends, and family; the impact of divorce; the coping skills required for a child to manage a migrainous nervous system; the potential secondary gain from headaches; psychiatric comorbidities and how to treat them; and the role of psychological intervention.

    Full Text Available One of the major causes of mortality in children younger than 5 years old is acute lower respiratory tract infections (ALRI. ALRI clinical features are cough, tachypnea, fever, coryza, chest retraction, crackles and wheeze. Increased white blood cell count with left shift might happen in pneumonia. C-reactive protein (CRP and erythrocyte sedimentation rate (ESR might rise in children with respiratory tract infections. Vitamin A deficiency is associated with severe childhood infections. The effect of vitamin A supplementation in childhood pneumonia depends on the prevalence and the level of vitamin A deficiency in the population. Some studies confirmed that retinol levels were significantly higher after recovery from acute pneumonia compared to acute phase. But there were no significant association between serum retinol level and the clinical manifestation.

It causes uncomfortable symptoms, impairs quality of life and can predispose to the development of comorbidities such as asthma. Etiological diagnosis is based on cutaneous prick tests, which have a high sensitivity and specificity rate and which can be easily applied to young children. Treatment initially involves avoidance measures and, when necessary, pharmacotherapy or immunotherapy. Pharmacotherapy generally involves antihistamines and/or nasal corticosteroids, but leukotriene antagonists have also demonstrated effectiveness in treating allergic rhinitis symptoms. In this article, the symptoms, diagnosis and treatment of allergic rhinitis in childhood are discussed. (Journal of Current Pediatrics 2010; 8: 105-12

    Full Text Available In this review, the relationship between very low frequency electromagnetic fields, originating from high voltage powerlines, and childhood leukemia was evaluated. Electromagnetic fields have biological effects. Whole populations are effected by different levels of electromagnetic fields but children are more sensible. In urban areas high voltage powerlines are the main sources of electromagnetic fields. The relation of electromagnetic fields due to high voltage powerlines and leukemia with consideration of dose-response and distance is investigated in several studies. There are different opinions on the effects of electromagnetic fields on general health. The relation between electromagnetic fields and childhood leukemia must be considered separately. Although there is no limit value, it is generally accepted that exposure to 0.4 µT and over doubles the risk of leukemia in children 15 years and younger.

  20. Decision Making in Action

    1994-01-01

    The importance of decision-making to safety in complex, dynamic environments like mission control centers and offshore installations has been well established. NASA-ARC has a program of research dedicated to fostering safe and effective decision-making in the manned spaceflight environment. Because access to spaceflight is limited, environments with similar characteristics, including aviation and nuclear power plants, serve as analogs from which space-relevant data can be gathered and theories developed. Analyses of aviation accidents cite crew judgement and decision making as causes or contributing factors in over half of all accidents. A similar observation has been made in nuclear power plants. Yet laboratory research on decision making has not proven especially helpful in improving the quality of decisions in these kinds of environments. One reason is that the traditional, analytic decision models are inappropriate to multidimensional, high-risk environments, and do not accurately describe what expert human decision makers do when they make decisions that have consequences. A new model of dynamic, naturalistic decision making is offered that may prove useful for improving decision making in complex, isolated, confined and high-risk environments. Based on analyses of crew performance in full-mission simulators and accident reports, features that define effective decision strategies in abnormal or emergency situations have been identified. These include accurate situation assessment (including time and risk assessment), appreciation of the complexity of the problem, sensitivity to constraints on the decision, timeliness of the response, and use of adequate information. More effective crews also manage their workload to provide themselves with time and resources to make good decisions. In brief, good decisions are appropriate to the demands of the situation. Effective crew decision making and overall performance are mediated by crew communication. Communication

    Children and adolescents are prone to avulsive injuries related to a combination of their propensity for great strength, ability to sustain extreme levels of activity, and immature growing apophyses. Appropriate interpretation of imaging studies showing chronic avulsive injuries is essential so that the irregularity and periostitis that can be associated with chronic avulsions is not misinterpreted as probable malignancy.

    Full Text Available Until recently, it has not been put much emphasis on obesity in children and the view of “obese child is healthy” is widely accepted by families. However, understanding that a close relation exists between obesity prevalence and childhood obesity, which increased in recent years both across the world and in our country, and many diseases such as hypertension, diabetes, cardiovascular diseases changed the opinion of both of health care professionals and the society about childhood obesity in Turkey, like it changed the opinion in all around the world. Although there are no studies in our country, which have been conducted to investigate obesity prevalence and affecting factors in children nationwide, it is reported in studies carried out in various cities that rate of overweight children in preschool children is between 4-13%, whereas rate of obese children is between 9-27%. In the literature, a positive correlation was found between the frequency of taking the children to fast-food restaurants, compelling children to eat foods on their dishes, one or two of the parents being obese and obesity of children in Turkey. In this review will focus on the risk factors of childhood obesity in Turkey. (Journal of Current Pediatrics 2013; 11: 27-30

  3. The dynamics of childhood poverty.

    1997-01-01

    Child poverty rates have remained high since the middle of the 1970s. While several trends, including declines in the number of children per family and increases in parental years of schooling, worked to reduce child poverty rates, several others, including show economic growth, widening economic inequality, and increases in the proportion of children living in mother-only families, had the opposite effect, pushing more children into poverty. Poverty is a common risk: One-third of all children will be poor for at least one year. For many, poverty lasts only a short while, but for a small percentage, poverty persists both throughout childhood and into the adult years. Poverty is not shared equally across different demographic groups. African-American children. Latino children, and children in mother-only families are disproportionately poor. Long-term poverty is even more concentrated than single-year poverty. In 1992, almost 90% of long-term poor children were African-American as compared to all poor children (single-year and long-term poor), of whom 60% were white. Both family structure and the labor market are implicated in long-term childhood poverty. Changes in employment of family members and changes in family composition are each strongly associated with transitions into and out of childhood poverty. Of these, changes in employment are the most important.

  9. Immunity in urogenital protozoa.

    Science.gov (United States)

    Malla, N; Goyal, K; Dhanda, R S; Yadav, M

    2014-09-01

    Innate and adaptive immunity play a significant role in urogenital infections. Innate immunity is provided by the epithelial cells and mucus lining along with acidic pH, which forms a strong physical barrier against the pathogens in female reproductive tract. Cells of innate immune system, antimicrobial peptides, cytokines, chemokines and adaptive immunity in the reproductive tract are evolved during infection, and a pro-inflammatory response is generated to fight against the invading pathogen Trichomonas vaginalis, a primary urogenital protozoa, the etiological agent of human trichomoniasis, a curable sexually transmitted infection. The involvement of the urogenital tract by other protozoal infections such as P. falciparum, Trypanosoma, Leishmania, Toxoplasma, Entamoeba histolytica and Acanthamoeba infection is rarely reported. Trichomonas induce pro-inflammatory and immunosuppressive responses in infected subjects. Multifactorial pathogenic mechanisms including parasite adherence, cysteine proteases, lipophosphoglycan, free radical, cytokine generation and Toll-like receptors appear to interplay with the induction of local and systemic immune responses that ultimately determine the outcome of the infection. However, the involvement of urogenital pathogen-specific immune mechanisms and effect of normal local resident flora on the outcome (symptomatic vs. asymptomatic) of infection are poorly understood. Moreover, immune interactions in trichomoniasis subjects co-infected with bacterial and viral pathogens need to be elucidated.

  10. Parents' help-seeking behaviours during acute childhood illness at home: A contribution to explanatory theory.

    Neill, Sarah J; Jones, Caroline H D; Lakhanpaul, Monica; Roland, Damian T; Thompson, Matthew J

    2016-03-01

    Uncertainty and anxiety surround parents' decisions to seek medical help for an acutely ill child. Consultation rates for children are rising, yet little is known about factors that influence parents' help-seeking behaviours. We used focus groups and interviews to examine how 27 parents of children under five years, from a range of socioeconomic groups in the East Midlands of England, use information to make decisions during acute childhood illness at home. This article reports findings elucidating factors that influence help-seeking behaviours. Parents reported that decision-making during acute childhood illness was influenced by a range of personal, social and health service factors. Principal among these was parents' concern to do the right thing for their child. Their ability to assess the severity of the illness was influenced by knowledge and experience of childhood illness. When parents were unable to access their general practitioner (GP), feared criticism from or had lost trust in their GP, some parents reported using services elsewhere such as Accident and Emergency. These findings contribute to explanatory theory concerning parents' help-seeking behaviours. Professional and political solutions have not reduced demand; therefore, collaborative approaches involving the public and professionals are now needed to improve parents' access to information.

  15. Safer sexual decision making in adolescent women: perspectives from the conflict theory of decision-making.

    Chambers, Kathryn B; Rew, Lynn

    2003-01-01

    Adolescent women are at risk for unintended pregnancies and sexually transmitted diseases, including human immune deficiency virus (HIV)/acquired immunodeficiency deficiency syndrome (AIDS), if they do not engage in safer sexual practices. Adolescent women are biologically, behaviorally, and socially more at risk for sexually transmitted diseases (STDs) and HIV than adolescent men. Although abstinence is the safest sexual health practice for adolescent women, once sexual activity begins, safer sexual practices involve condom and contraceptive use, and communicating with sexual partners to negotiate condom use. A number of implicit and explicit decisions are involved in these activities. A number of researchers have examined safer sexual decisions of adolescent women, some of whom have used theory models such as the Transtheoretical Model of Change. Although these findings have contributed to the knowledge base about safer sexual decision making, many questions remain unanswered about how adolescent women make safer sexual decisions. The Conflict Model of Decision Making is presented and discussed as a framework for enhanced understanding of safer sexual decision making by adolescent women.

    2009-11-01

    The visualization of the dynamic behaviour of and interactions between immune cells using time-lapse video microscopy has an important role in modern immunology. To draw robust conclusions, quantification of such cell migration is required. However, imaging experiments are associated with various artefacts that can affect the estimated positions of the immune cells under analysis, which form the basis of any subsequent analysis. Here, we describe potential artefacts that could affect the interpretation of data sets on immune cell migration. We propose how these errors can be recognized and corrected, and suggest ways to prevent the data analysis itself leading to biased results.

A number of key general properties observed in the biological innate and adaptive immune systems were highlighted, and how such properties might be instantiated in artificial systems was discussed in detail. The next logical step is to take these ideas and build a software system with which AISs with these properties can be implemented and experimentally evaluated. This paper reports on the results of that step - the libtissue system.

    Karny, Miroslav; Wolpert, David

    2013-01-01

    Decision making (DM) is ubiquitous in both natural and artificial systems. The decisions made often differ from those recommended by the axiomatically well-grounded normative Bayesian decision theory, in a large part due to limited cognitive and computational resources of decision makers (either artificial units or humans). This state of a airs is often described by saying that decision makers are imperfect and exhibit bounded rationality. The neglected influence of emotional state and personality traits is an additional reason why normative theory fails to model human DM process.   The book is a joint effort of the top researchers from different disciplines to identify sources of imperfection and ways how to decrease discrepancies between the prescriptive theory and real-life DM. The contributions consider:   ·          how a crowd of imperfect decision makers outperforms experts' decisions;   ·          how to decrease decision makers' imperfection by reducing knowledge available;   ...

    2014-01-01

    This chapter, dedicated to the memory of Mino Freund, summarizes the Quantum Decision Theory (QDT) that we have developed in a series of publications since 2008. We formulate a general mathematical scheme of how decisions are taken, using the point of view of psychological and cognitive sciences, without touching physiological aspects. The basic principles of how intelligence acts are discussed. The human brain processes involved in decisions are argued to be principally different from straightforward computer operations. The difference lies in the conscious-subconscious duality of the decision making process and the role of emotions that compete with utility optimization. The most general approach for characterizing the process of decision making, taking into account the conscious-subconscious duality, uses the framework of functional analysis in Hilbert spaces, similarly to that used in the quantum theory of measurements. This does not imply that the brain is a quantum system, but just allows for the simple...

    Doya, Kenji

    2008-04-01

    Human and animal decisions are modulated by a variety of environmental and intrinsic contexts. Here I consider computational factors that can affect decision making and review anatomical structures and neurochemical systems that are related to contextual modulation of decision making. Expectation of a high reward can motivate a subject to go for an action despite a large cost, a decision that is influenced by dopamine in the anterior cingulate cortex. Uncertainty of action outcomes can promote risk taking and exploratory choices, in which norepinephrine and the orbitofrontal cortex appear to be involved. Predictable environments should facilitate consideration of longer-delayed rewards, which depends on serotonin in the dorsal striatum and dorsal prefrontal cortex. This article aims to sort out factors that affect the process of decision making from the viewpoint of reinforcement learning theory and to bridge between such computational needs and their neurophysiological substrates.

    Immunity rules are part and parcel of the law of international organizations. It has long been accepted that international organizations and their staff need to enjoy immunity from the jurisdiction of national courts. However, it is the application of these rules in practice that increasingly causes controversy. Claims against international organizations are brought before national courts by those who allegedly suffer from their activities. These can be both natural and legal persons such as companies. National courts, in particular lower courts, have often been less willing to recognize the immunity of the organization concerned than the organization s founding fathers. Likewise, public opinion and legal writings frequently criticize international organizations for invoking their immunity and for the lack of adequate means of redress for claimants. It is against this background that an international conference was organized at Leiden University in June 2013. A number of highly qualified academics and practit...

    2011-11-01

    Although a variety of virus species can infect amphibians, diseases caused by ranaviruses ([RVs]; Iridoviridae) have become prominent, and are a major concern for biodiversity, agriculture and international trade. The relatively recent and rapid increase in prevalence of RV infections, the wide range of host species infected by RVs, the variability in host resistance among population of the same species and among different developmental stages, all suggest an important involvement of the amphibian immune system. Nevertheless, the roles of the immune system in the etiology of viral diseases in amphibians are still poorly investigated. We review here the current knowledge of antiviral immunity in amphibians, focusing on model species such as the frog Xenopus and the salamander (Ambystoma tigrinum), and on recent progress in generating tools to better understand how host immune defenses control RV infections, pathogenicity, and transmission.

Innate immune system consisting of pattern-recognition receptors, macrophages, and complement system plays a key role in CNS homeostasis following injury and infection. Here, we discuss how innate immune components can also contribute to neuroinflammation and neurodegeneration.

    Pentraxin-3 (PTX3) is a multifactorial protein involved in immunity and inflammation, which is rapidly produced and released by several cell types in response to inflammatory signals. It may be suggested that PTX3 is related to periodontal tissue inflammation. Its salivary concentrations may have a diagnostic potential.

    All organisms are connected in a complex web of relationships. Although many of these are benign, not all are, and everything alive devotes significant resources to identifying and neutralizing threats from other species. From bacteria through to primates, the presence of some kind of effective immune system has gone hand in hand with evolutionary success. This article focuses on mammalian immunity, the challenges that it faces, the mechanisms by which these are addressed, and the consequences that arise when it malfunctions.

  4. Secular trends in new childhood epidemics: insights from evolutionary medicine.

    2013-10-21

    In the last few decades, pediatric medicine has observed a dramatic increase in the prevalence of hitherto rare illnesses, among which obesity, diabetes, allergies and other autoimmune diseases stand out. In addition, secular trends towards earlier onset of puberty and sexual activity contribute to the psychological problems of youth and adolescents. All this has occurred in spite of the improved health care provision for children, yet traditional concepts of medicine have failed to explain these new "epidemics". A recent conference and science school of the European Society of Paediatric Endocrinology (ESPE) in Acre, Israel, has taken up this challenge. Experts across disciplines including medicine, anthropology and developmental psychology discussed potential causes of childhood ill-health from an evolutionary point-of-view. Seen from an evolutionary vantage point, the "epidemics" of childhood obesity, diabetes and psychological dysfunction appear, in part, to be related to a mismatch between ancestral adaptations and novel environmental contingencies. These include changing exposures to pathogens, which impact on the function of the immune system, as well as changing patterns of parenting, which influence the timing of puberty and the risk for developing psychopathology.

  5. Early influences and childhood development. Does helicobacter play a role?

    Science.gov (United States)

    Lee, Adrian

    2007-11-01

    In the late 1960s, Rene Dubos showed that a variety of nutritional stress in utero or in early infancy could have dramatic impact on childhood development that was irreversible. This included detectable changes in the brain. Since that time, iron deficiency anemia (IDA) has been identified as one of the major nutritional stresses that leads to permanent behavioral changes in both experimental animals and humans resulting in poorer cognitive, motor, and social-emotional function. It has been proposed that these changes play an important part in the inter-generational transmission of poverty. More recently, it is becoming clear that Helicobacter pylori causes IDA in populations on an iron-limiting diet. The main thesis of this article is that H. pylori infection may indeed have an impact on childhood development and that much more research is needed in this area as intervention via immunization or antimicrobial therapy in populations in the developing world may have major positive benefits via cure of IDA and prevention of brain damage in the young.

  6. [Childhood vaccines and autism--much ado about nothing?].

    Solt, Ido; Bornstein, Jacob

    2010-04-01

    The increased diagnoses of autism and developmental disorders in recent decades, together with the childhood vaccination program, has led to the hypothesis that vaccination in general, and the measles, mumps, and rubella virus live vaccine, and vaccines that contain mercury, in particular, cause autism. It has been hypothesized that intestinal infection caused by live virus vaccines change the permeability of the intestinal wall, and subsequently, the passage of peptides through the intestinal wall to the blood, and from there to the brain. It has been suggested that the accumulation of these peptides in the central nervous system causes autism. Studies that investigated this theory did not find an association between vaccine administration and between digestive system symptoms and autism. According to a second hypothesis, an organomercury compound (Thimerosal), used as a preservative in vaccines that do not include live viruses, is a cause of autism. Like the former, this hypothesis has been well researched, and refuted. Some studies have in fact found an increase in autism diagnosis among children who were vaccinated after Thimerosal was removed from the vaccine preparation. Recent studies have refuted the theory that the consecutive administration of vaccines weakens the young immune system in children, and leads to an autoimmune process that causes autism. The etiology of autism is still unknown, with research continuing from different directions. The extensive research conducted so far indicates that childhood vaccination is not a cause of the sharp increase in autism diagnoses in recent decades.

    The prevalence of food allergy in childhood increased in the last decades, especially in Westernized countries where this phenomenon has been indicated as a second wave of the allergic epidemic. In parallel, scientific interest also increased with the effort to explain the reasons of this sudden rise and to identify potential protective and risk factors. A great attention has been focused on early exposures to allergenic foods, as well as on other nutritional factors or supplements that may influence the immune system in a positive direction. Both interventions on maternal diet before birth or during breastfeeding and then directly on infant nutrition have been investigated. Furthermore, the natural history of food allergy also seems to be changing over time; IgE-mediated cow's milk allergy and egg allergy seem to be more frequently a persistent rather than a transient disease in childhood, as described in the last years. Food avoidance and the emergency drugs in case of an adverse event, such as epinephrine self-injector, are currently the first-line treatment in patients with food allergies, with a resulting impairment in the quality of life and social behaviour. During the last decade, oral immunotherapy emerged as an optional treatment with remarkable results, offering a novel perspective in the treatment for and management of food allergy.

    The biological immune system is a robust, complex, adaptive system that defends the body from foreign pathogens. It is able to categorize all cells (or molecules) within the body as self-cells or non-self cells. It does this with the help of a distributed task force that has the intelligence to take action from a local and also a global perspective using its network of chemical messengers for communication. There are two major branches of the immune system. The innate immune system is an unchanging mechanism that detects and destroys certain invading organisms, whilst the adaptive immune system responds to previously unknown foreign cells and builds a response to them that can remain in the body over a long period of time. This remarkable information processing biological system has caught the attention of computer science in recent years. A novel computational intelligence technique, inspired by immunology, has emerged, called Artificial Immune Systems. Several concepts from the immune have been extracted an...

  10. Mammalian gut immunity

    Directory of Open Access Journals (Sweden)

    Benoit Chassaing

    2014-10-01

    Full Text Available The mammalian intestinal tract is the largest immune organ in the body and comprises cells from non-hemopoietic (epithelia, Paneth cells, goblet cells and hemopoietic (macrophages, dendritic cells, T-cells origin, and is also a dwelling for trillions of microbes collectively known as the microbiota. The homeostasis of this large microbial biomass is prerequisite to maintain host health by maximizing beneficial symbiotic relationships and minimizing the risks of living in such close proximity. Both microbiota and host immune system communicate with each other to mutually maintain homeostasis in what could be called a "love-hate relationship." Further, the host innate and adaptive immune arms of the immune system cooperate and compensate each other to maintain the equilibrium of a highly complex gut ecosystem in a stable and stringent fashion. Any imbalance due to innate or adaptive immune deficiency or aberrant immune response may lead to dysbiosis and low-grade to robust gut inflammation, finally resulting in metabolic diseases.

  11. Breaking Patterns of Environmentally Influenced Disease for Health Risk Reduction: Immune Perspectives

    Dietert, Rodney R.; DeWitt, Jamie C.; Germolec, Dori R.; Zelikoff, Judith T.

    2010-01-01

    Background Diseases rarely, if ever, occur in isolation. Instead, most represent part of a more complex web or “pattern” of conditions that are connected via underlying biological mechanisms and processes, emerge across a lifetime, and have been identified with the aid of large medical databases. Objective We have described how an understanding of patterns of disease may be used to develop new strategies for reducing the prevalence and risk of major immune-based illnesses and diseases influenced by environmental stimuli. Findings Examples of recently defined patterns of diseases that begin in childhood include not only metabolic syndrome, with its characteristics of inflammatory dysregulation, but also allergic, autoimmune, recurrent infection, and other inflammatory patterns of disease. The recent identification of major immune-based disease patterns beginning in childhood suggests that the immune system may play an even more important role in determining health status and health care needs across a lifetime than was previously understood. Conclusions Focusing on patterns of disease, as opposed to individual conditions, offers two important venues for environmental health risk reduction. First, prevention of developmental immunotoxicity and pediatric immune dysfunction can be used to act against multiple diseases. Second, pattern-based treatment of entryway diseases can be tailored with the aim of disrupting the entire disease pattern and reducing the risk of later-life illnesses connected to underlying immune dysfunction. Disease-pattern–based evaluation, prevention, and treatment will require a change from the current approach for both immune safety testing and pediatric disease management. PMID:20483701

    2009-05-01

    Full Text Available Abstract Background The incidence and morbidity of wheezing illnesses and childhood asthma is especially high in poor urban areas. This paper describes the study design, methods, and population of the Urban Environment and Childhood Asthma (URECA study, which was established to investigate the immunologic causes of asthma among inner-city children. Methods and Results URECA is an observational prospective study that enrolled pregnant women in central urban areas of Baltimore, Boston, New York City, and St. Louis and is following their offspring from birth through age 7 years. The birth cohort consists of 560 inner-city children who have at least one parent with an allergic disease or asthma, and all families live in areas in which at least 20% of the population has incomes below the poverty line. In addition, 49 inner-city children with no parental history of allergies or asthma were enrolled. The primary hypothesis is that specific urban exposures in early life promote a unique pattern of immune development (impaired antiviral and increased Th2 responses that increases the risk of recurrent wheezing and allergic sensitization in early childhood, and of asthma by age 7 years. To track immune development, cytokine responses of blood mononuclear cells stimulated ex vivo are measured at birth and then annually. Environmental assessments include allergen and endotoxin levels in house dust, pre- and postnatal maternal stress, and indoor air nicotine and nitrogen dioxide. Nasal mucous samples are collected from the children during respiratory illnesses and analyzed for respiratory viruses. The complex interactions between environmental exposures and immune development will be assessed with respect to recurrent wheeze at age 3 years and asthma at age 7 years. Conclusion The overall goal of the URECA study is to develop a better understanding of how specific urban exposures affect immune development to promote wheezing illnesses and asthma.

    A revolution in the science of emotion has emerged in recent decades, with the potential to create a paradigm shift in decision theories. The research reveals that emotions constitute potent, pervasive, predictable, sometimes harmful and sometimes beneficial drivers of decision making. Across different domains, important regularities appear in the mechanisms through which emotions influence judgments and choices. We organize and analyze what has been learned from the past 35 years of work on emotion and decision making. In so doing, we propose the emotion-imbued choice model, which accounts for inputs from traditional rational choice theory and from newer emotion research, synthesizing scientific models.

    Mendez, Robert; Grissom, Maureen

    2013-07-01

    The incidence of childhood obesity in the United States is estimated at 17%, or 12 million children ages 2 to 19 years. Obesity is a multifactorial condition with syndromic and nonsyndromic variants. Genetic, social, ethnic, endocrinologic, and behavioral issues are all potential etiologic factors. Preventive efforts should begin with monitoring from birth and include breastfeeding until age 6 months, avoiding juices, and promoting fruit and vegetable consumption and adequate exercise. Childhood obesity is diagnosed based on body mass index; a child is considered overweight at the 85th to 95th percentiles and obese at or above the 95th percentile. After obesity is diagnosed, testing should include blood pressure levels, fasting lipid profile, diabetes screening, and liver function tests. The physician should obtain a detailed history of the physical activity level and food intake and assess possible complications of obesity, including depression and hypertension, annually. Lifestyle interventions with family involvement are the mainstay of management, with pharmacotherapy or bariatric surgery considered for adolescents only if intensive lifestyle modifications have failed and in the presence of comorbidities. Intervention by multiple disciplines (ie, medicine, nutrition, psychology) is recommended, and family physicians are encouraged to become more involved in encouraging physical activity and improved nutrition for children.

    JAGL differs from the Global Initiative for Asthma Guideline (GINA in that the former emphasizes long-term management of childhood asthma based on asthma severity and early diagnosis and intervention at <2 years and 2–5 years of age. However, a management method, including step-up or step-down of long-term management agents based on the status of asthma symptoms, is easy to understand and thus JAGL is suitable for routine medical treatment. JAGL also introduced treatment and management using a control test for children, recommending treatment and management aimed at complete control through avoiding exacerbation factors and appropriate use of antiinflammatory agents.

  5. Factors associated with childhood obesity.

    Science.gov (United States)

    Dietz, W

    1991-01-01

    Childhood obesity is associated with host factors that enhance susceptibility and environmental factors that increase food intake and decrease energy expenditure. Obese children underreport food intake and probably consume more food to maintain their weight at increased levels. Prevalence of obesity is related to family variables, including parental obesity, family size and age, and socioeconomic status. Television viewing is strongly associated with the prevalence of obesity through its impact on food intake and activity. How these environmental variables are behaviorally interrelated to the genesis of obesity is unclear.

    The extended immunization campaign began in the mid 1980s and contributed to immunization of 4 out of every 5 infants worldwide, or 80% by the end of the 1980s. There was a slight relaxation of effort around 1990 and 1991, and declines occurred in 28 developing countries. In developing countries, 101 countries maintained or increased immunization in 1991. Rates dropped in Brazil and Venezuela and sub-Saharan Africa. Rates remained constant in 1992, except for the declines in women's tetanus immunization. Distribution is 4-5 times a year to 100 million infants. The savings in lives amounted to 3 million 1992, and further extension could have saved another 1.7 million. The cost in low income countries is $6 to $20, with an average of $15. Five visits are required for complete immunization into one dose; costs could then be reduced by 70%. Total annual costs amount to $2.2 to $2.4 billion for the United Nations Expanded Programme on Immunization. This sum amounts to 2% of public health expenditures in developing countries. The benefits are in reduction in health care costs and expanded productive potential of people. The measles vaccine alone reduced the death rate from 2.5 million in 1980 to 900,000 in 1990. Nonfatal measles morbidity was reduced from 75 million to 25 million for the same period. From averted measles incidents, the savings in treatment costs and productive potential are immeasurable. The first smallpox vaccine was developed in 1796 by Edward Jenner, but it took nearly two for final smallpox eradication in 1979 worldwide. Over the past 10 years, polio eradication has cost $1.4 billion, but without polio vaccines, the cost would reach $500 million annually. Refrigeration and transportation to remote areas has made immunization difficult. The development of low-dose vaccines that would maintain potency in tropical temperatures would be a welcome contribution.

    There is growing concern about elevated blood pressure (BP) in children. The evidence for familial aggregation of childhood BP is substantial. Twin studies have shown that a large part of the familial aggregation of childhood BP is due to genes. The first part of this review provides the latest progress in gene finding for childhood BP, focusing on the combined effects of multiple loci identified from the genome-wide association studies on adult BP. We further review the evidence on the contribution of the genetic components of other family risk factors to the familial aggregation of childhood BP including obesity, birth weight, sleep quality, sodium intake, parental smoking, and socioeconomic status. At the end, we emphasize the promise of using genomic-relatedness-matrix restricted maximum likelihood (GREML) analysis, a method that uses genome-wide data from unrelated individuals, in answering a number of unsolved questions in the familial aggregation of childhood BP.

    Survivors of childhood cancer are at risk of long-term adverse effects and late effects of the disease and/or its treatment. In response to national recommendations to improve evidence-based follow-up care, a web-based support system for clinical decision making, the Passport for Care (PFC), was developed for use at the point of care to produce screening recommendations individualized to the survivor. To date, the PFC has been implemented in over half of the nearly 200 clinics affiliated with the Children's Oncology Group across the USA. Most clinician users report that the PFC has been integrated into clinic workflows, and that it fosters improved conversations with survivors about the potential late effects a survivor might experience and about the screening and/or behavioural interventions recommended to improve health status. Furthermore, clinicians using the PFC have indicated that they adhered more closely to follow-up care guidelines. Perspectives on the challenges encountered and lessons learned during the development and deployment of the PFC are reviewed and contrasted with other nationwide approaches to the provision of guidance on survivor follow-up care; furthermore, the implications for the care of childhood cancer survivors are discussed.

    Full Text Available RATIONALE AND OBJECTIVE: Autophagy is a cellular process directed at eliminating or recycling cellular proteins. Recently, the autophagy pathway has been implicated in immune dysfunction, the pathogenesis of inflammatory disorders, and response to viral infection. Associations between two genes in the autophagy pathway, ATG5 and ATG7, with childhood asthma were investigated. METHODS: Using genetic and experimental approaches, we examined the association of 13 HapMap-derived tagging SNPs in ATG5 and ATG7 with childhood asthma in 312 asthmatic and 246 non-allergic control children. We confirmed our findings by using independent cohorts and imputation analysis. Finally, we evaluated the functional relevance of a disease associated SNP. MEASUREMENTS AND MAIN RESULTS: We demonstrated that ATG5 single nucleotide polymorphisms rs12201458 and rs510432 were associated with asthma (p = 0.00085 and 0.0025, respectively. In three independent cohorts, additional variants in ATG5 in the same LD block were associated with asthma (p<0.05. We found that rs510432 was functionally relevant and conferred significantly increased promotor activity. Furthermore, Atg5 expression was increased in nasal epithelium of acute asthmatics compared to stable asthmatics and non-asthmatic controls. CONCLUSION: Genetic variants in ATG5, including a functional promotor variant, are associated with childhood asthma. These results provide novel evidence for a role for ATG5 in childhood asthma.

    Recent findings related to childhood leukaemia incidence near nuclear installations have raised questions which can be answered neither by current knowledge on radiation risk nor by other established risk factors. In 2012, a workshop was organised on this topic with two objectives: (a) review of results and discussion of methodological limitations of studies near nuclear installations; (b) identification of directions for future research into the causes and pathogenesis of childhood leukaemia. The workshop gathered 42 participants from different disciplines, extending widely outside of the radiation protection field. Regarding the proximity of nuclear installations, the need for continuous surveillance of childhood leukaemia incidence was highlighted, including a better characterisation of the local population. The creation of collaborative working groups was recommended for consistency in methodologies and the possibility of combining data for future analyses. Regarding the causes of childhood leukaemia, major fields of research were discussed (environmental risk factors, genetics, infections, immunity, stem cells, experimental research). The need for multidisciplinary collaboration in developing research activities was underlined, including the prevalence of potential predisposition markers and investigating further the infectious aetiology hypothesis. Animal studies and genetic/epigenetic approaches appear of great interest. Routes for future research were pointed out.

  11. Psychiatric presentation of childhood epilepsy: Case series and review

    2016-01-01

    Full Text Available Childhood-onset epilepsy has a varied presentation and may have different etiological factors. A multiaxial diagnostic approach should be used before making treatment and management decisions for any individual patient. It is widely accepted that distinction among primary psychiatric disorders, epilepsy, and nonepileptic seizures is a challenge for physicians. This case series demonstrated the identification of three atypical presentations of seizures in children on the basis of detailed history taking and electroencephalogram findings, despite having normal findings in neurological examination and magnetic resonance imaging. We report three rare cases of atypical presentation in epilepsy in patients with symptoms of episodic hallucinations, rage attacks, and secondary enuresis. Clinically, the diagnosis of epilepsy can be strengthened by paying sufficient attention to detailed history and symptom spectrum of partial epilepsy.

    Armstrong, Stuart

    2011-01-01

    This paper sets out to solve the Sleeping Beauty problem and various related anthropic problems, not through the calculation of anthropic probabilities, but through finding the correct decision to make. Given certain simple assumptions, it turns out to be possible to do so without knowing the underlying anthropic probabilities. Most common anthropic problems are underspecified from the decision perspective, and this can explain some of the differing intuitions in the subject: selfless and selfish agents, total and average utilitarians, will all reach different decisions in the same problem. These results are formalised into an anthropic decision theory, that is them used to solve many anthropic problems and paradoxes, such as the Presumptuous Philosopher, Adam and Eve, and Doomsday problems.

    The most popular models of decision making use a single criterion to evaluate projects or lotteries. However, decision makers may actually consider multiple criteria when evaluating projects. We consider a dual criteria model from psychology. This model integrates the familiar tradeoffs between...... risk and utility that economists traditionally assume, allowance for rank-dependent decision weights, and consideration of income thresholds. We examine the issues involved in full maximum likelihood estimation of the model using observed choice data. We propose a general method for integrating...... the multiple criteria, using the logic of mixture models, which we believe is attractive from a decision-theoretic and statistical perspective. The model is applied to observed choices from a major natural experiment involving intrinsically dynamic choices over highly skewed outcomes. The evidence points...

  20. Immunity to Fish Rhabdoviruses

    Directory of Open Access Journals (Sweden)

    Maureen K. Purcell

    2012-01-01

    Full Text Available Members of the family Rhabdoviridae are single-stranded RNA viruses and globally important pathogens of wild and cultured fish and thus relatively well studied in their respective hosts or other model systems. Here, we review the protective immune mechanisms that fish mount in response to rhabdovirus infections. Teleost fish possess the principal components of innate and adaptive immunity found in other vertebrates. Neutralizing antibodies are critical for long-term protection from fish rhabdoviruses, but several studies also indicate a role for cell-mediated immunity. Survival of acute rhabdoviral infection is also dependent on innate immunity, particularly the interferon (IFN system that is rapidly induced in response to infection. Paradoxically, rhabdoviruses are sensitive to the effects of IFN but virulent rhabdoviruses can continue to replicate owing to the abilities of the matrix (M protein to mediate host-cell shutoff and the non‑virion (NV protein to subvert programmed cell death and suppress functional IFN. While many basic features of the fish immune response to rhabdovirus infections are becoming better understood, much less is known about how factors in the environment affect the ecology of rhabdovirus infections in natural populations of aquatic animals.

  1. Adaptive Immunity to Fungi

    2015-01-01

    Life-threatening fungal infections have risen sharply in recent years, owing to the advances and intensity of medical care that may blunt immunity in patients. This emerging crisis has created the growing need to clarify immune defense mechanisms against fungi with the ultimate goal of therapeutic intervention. We describe recent insights in understanding the mammalian immune defenses that are deployed against pathogenic fungi. We focus on adaptive immunity to the major medically important fungi and emphasize three elements that coordinate the response: (1) dendritic cells and subsets that are mobilized against fungi in various anatomical compartments; (2) fungal molecular patterns and their corresponding receptors that signal responses and shape the differentiation of T-cell subsets and B cells; and, ultimately (3) the effector and regulatory mechanisms that eliminate these invaders while constraining collateral damage to vital tissue. These insights create a foundation for the development of new, immune-based strategies for prevention or enhanced clearance of systemic fungal diseases. PMID:25377140

  2. Iron overload and immunity

    Progress in the characterization of genes involved in the control of iron homeostasis in humans and in mice has improved the definition of iron overload and of the cells affected by it. The cell involved in iron overload with the greatest effect on immunity is the macrophage.Intriguing evidence has emerged, however, in the last 12 years indicating that parenchymal iron overload is linked to genes classically associated with the immune system. This review offers an update of the genes and proteins relevant to iron metabolism expressed in cells of the innate immune system, and addresses the question of how this system is affected in clinical situations of iron overload. The relationship between iron and the major cells of adaptive immunity, the T lymphocytes,will also be reviewed. Most studies addressing this last question in humans were performed in the clinical model of Hereditary Hemochromatosis. Data will also be reviewed demonstrating how the disruption of molecules essentially involved in adaptive immune responses result in the spontaneous development of iron overload and how they act as modifiers of iron overload.

    Age is the most important risk factor for tumorigenesis. More than 60% of new cancers and more than 70% of cancer deaths occur in elderly subjects >65 years. The immune system plays an important role in the battle of the host against cancer development. Deleterious alterations occur to the immune response with aging, termed immunosenescence. It is tempting to speculate that this waning immune response contributes to the higher incidence of cancer, but robust data on this important topic are few and far between. This review is devoted to discussing state of the art knowledge on the relationship between immunosenescence and cancer. Emerging understanding of the aging process at the molecular level is viewed from the perspective of this increased tumorigenesis. We also consider some of the most recent means to intervene in the modulation of immunosenescence to increase the ability of the immune system to fight against tumors. Future research will unravel new aspects of the immune response against tumors which will be modulable to decrease the burden of cancer in elderly individuals.

  4. Decisive Markov Chains

    Abdulla, Parosh Aziz; Mayr, Richard

    2007-01-01

    We consider qualitative and quantitative verification problems for infinite-state Markov chains. We call a Markov chain decisive w.r.t. a given set of target states F if it almost certainly eventually reaches either F or a state from which F can no longer be reached. While all finite Markov chains are trivially decisive (for every set F), this also holds for many classes of infinite Markov chains. Infinite Markov chains which contain a finite attractor are decisive w.r.t. every set F. In particular, this holds for probabilistic lossy channel systems (PLCS). Furthermore, all globally coarse Markov chains are decisive. This class includes probabilistic vector addition systems (PVASS) and probabilistic noisy Turing machines (PNTM). We consider both safety and liveness problems for decisive Markov chains, i.e., the probabilities that a given set of states F is eventually reached or reached infinitely often, respectively. 1. We express the qualitative problems in abstract terms for decisive Markov chains, and show...

  5. Geometric Decision Tree

    CERN Document Server

    Manwani, Naresh

    2010-01-01

    In this paper we present a new algorithm for learning oblique decision trees. Most of the current decision tree algorithms rely on impurity measures to assess the goodness of hyperplanes at each node while learning a decision tree in a top-down fashion. These impurity measures do not properly capture the geometric structures in the data. Motivated by this, our algorithm uses a strategy to assess the hyperplanes in such a way that the geometric structure in the data is taken into account. At each node of the decision tree, we find the clustering hyperplanes for both the classes and use their angle bisectors as the split rule at that node. We show through empirical studies that this idea leads to small decision trees and better performance. We also present some analysis to show that the angle bisectors of clustering hyperplanes that we use as the split rules at each node, are solutions of an interesting optimization problem and hence argue that this is a principled method of learning a decision tree.

  6. Childhood Pneumonia Screener: a concept

    Directory of Open Access Journals (Sweden)

    Jukka Räsänen

    2014-06-01

    Full Text Available Childhood pneumonia continues to be the number one cause of death in children under five years of age in developing countries. In addition to mortality, pneumonia constitutes an enormous economic and social burden because late diagnosis is associated with high cost of treatment and often leads to chronic health problems. There are several bottlenecks in developing countries in the case flow of a child with lung infection: 1 recognising the symptoms as a reason to seek care, 2 getting the patient to a first-tier health facility, 3 scarcity of trained healthcare personnel who can diagnose the condition and its severity, 4 access to a second-tier facility in severe cases. These factors are commonly present in rural areas but even in more urban settings, access to a physician is often delayed. The Childhood Pneumonia Screener project aims at bridging the diagnostic gap using emerging technology. Mobile “smart” phone communication with several inexpensive dedicated sensors is proposed as a rapid data-collection and transmission unit that is connected to a central location where trained personnel assisted by sophisticated signal processing algorithms, evaluate the data and determine if the child is likely to have pneumonia and what the level and urgency of care should be.

  7. Depersonalization, mindfulness, and childhood trauma.

    Depersonalization (DP), i.e., feelings of being detached from one's own mental processes or body, can be considered as a form of mental escape from the full experience of reality. This mental escape is thought to be etiologically linked with maltreatment during childhood. The detached state of consciousness in DP contrasts with certain aspects of mindfulness, a state of consciousness characterized by being in touch with the present moment. Against this background, the present article investigates potential connections between DP severity, mindfulness, and childhood trauma in a mixed sample of nonpatients and chronic nonmalignant pain patients. We found a strong inverse correlation between DP severity and mindfulness in both samples, which persisted after partialing out general psychological distress. In the nonpatient sample, we additionally found significant correlations between emotional maltreatment on the one hand and DP severity (positive) and mindfulness (negative) on the other. We conclude that the results first argue for an antithetical relationship between DP and certain aspects of mindfulness and thus encourage future studies on mindfulness-based interventions for DP and second throw light on potential developmental factors contributing to mindfulness.

  8. Catatonia in childhood and adolescence.

    2003-04-01

    Child and adolescent catatonia has been poorly investigated. A literature review was undertaken to clarify phenomenology, diagnosis, etiology, and treatment as well as ethical problems of catatonia in childhood and adolescence. Although there are no accepted standardized criteria for catatonia in childhood and adolescence, catatonic features described by child psychiatrists are similar to Diagnostic and Statistical Manual of Mental Disorders (4th edn; DSM-IV) criteria for catatonia. With respect to etiology, the motor and behavioral symptoms that are part of catatonia bear some similarities with those seen in autism. Several case reports suggest an association between catatonia and general medical conditions. Certain drugs abused by youngsters as well as prescribed medicine can induce catatonia. Regarding catatonic cases originally diagnosed as schizophrenia, it is unclear whether all of these cases should be identified as schizophrenia or whether some of them are pervasive developmental disorders that develop psychic features in adolescence. Environmental changes preceding the onset of catatonia in patients with mood disorder play a possibly important role. Examples that suggest stress-induced catatonia, although rare, also exist. A few patients exhibit features of malignant catatonia, some without taking neuroleptics and others having taken them. Benzodiazepines and electroconvulsive therapy are considered to be effective treatments for catatonic youngsters.

    2012-01-01

    Full Text Available In an immune system, dendritic cells (DCs are professional antigen-presenting cells (APCs as well as powerful sensors of danger signals. When DCs receive signals from infection and tissue stress, they immediately activate and instruct the initiation of appropriate immune responses to T cells. However, it has remained unclear how the tissue microenvironment in a steady state shapes the function of DCs. Recent many works on thymic stromal lymphopoietin (TSLP, an epithelial cell-derived cytokine that has the strong ability to activate DCs, provide evidence that TSLP mediates crosstalk between epithelial cells and DCs, involving in DC-mediated immune homeostasis. Here, we review recent progress made on how TSLP expressed within the thymus and peripheral lymphoid and non-lymphoid tissues regulates DC-mediated T-cell development in the thymus and T-cell homeostasis in the periphery.

    Huang, Yuan; Chen, Zhonge

    2016-01-01

    Inflammatory bowel disease (IBD) is a chronic nonspecific intestinal inflammatory disease, including ulcerative colitis (UC) and Crohn’s disease (CD). Its pathogenesis remains not yet clear. Current researchers believe that after environmental factors act on individuals with genetic susceptibility, an abnormal intestinal immune response is launched under stimulation of intestinal flora. However, previous studies only focused on adaptive immunity in the pathogenesis of IBD. Currently, roles of innate immune response in the pathogenesis of intestinal inflammation have also drawn much attention. In this study, IBD related innate immunity and adaptive immunity were explained, especially the immune mechanisms in the pathogenesis of IBD. PMID:27398134

    The paper is devoted to the analysis of greedy algorithms for the minimization of average depth of decision trees for decision tables such that each row is labeled with a set of decisions. The goal is to find one decision from the set of decisions. When we compare with the optimal result obtained from dynamic programming algorithm, we found some greedy algorithms produces results which are close to the optimal result for the minimization of average depth of decision trees.

    Vaccines are among most cost-effective public health strategies. Despite effective vaccines for many bacterial and viral illnesses, tens of thousands of adults and hundreds of children die each year in the United States from vaccine-preventable diseases. Underutilization of vaccines requires rethinking the approach to incorporating vaccines into practice. Arguably, immunizations could be a part all health care encounters. Shared responsibility is paramount if deaths are to be reduced.

    In vitro and some animal models have shown that quercetin, a polyphenol derived from plants, has a wide range of biological actions including anti-carcinogenic, anti-inflammatory and antiviral activities; as well as attenuating lipid peroxidation, platelet aggregation and capillary permeability. This review focuses on the physicochemical properties, dietary sources, absorption, bioavailability and metabolism of quercetin, especially main effects of quercetin on inflammation and immune function. According to the results obtained both in vitro and in vivo, good perspectives have been opened for quercetin. Nevertheless, further studies are needed to better characterize the mechanisms of action underlying the beneficial effects of quercetin on inflammation and immunity.

    Full Text Available Pentraxin-3 (PTX3 is a multifactorial protein involved in immunity and inflammation, which is rapidly produced and released by several cell types in response to inflammatory signals. It may be suggested that PTX3 is related to periodontal tissue inflammation. Its salivary concentrations may have a diagnostic potential. Pentraxin-3 (PTX3 is an ancient family of multifactorial proteins involved in immunity and inflammation. They are rapidly produced and released by various types of cells when there are indications of inflammation. PTX3 is related to inflammation in the periodontal tissue and it can be suggested that salivary concentrations may be used for diagnosing the same.

    Ageing is associated with a decline in normal functioning of the immune system described as 'immunosenescence'. This contributes to poorer vaccine response and increased incidence of infection and malignancy seen in older people. Regular exercise can enhance vaccination response, increase T-cells and boost the function of the natural killer cells in the immune system. Exercise also lowers levels of the inflammatory cytokines that cause the 'inflamm-ageing' that is thought to play a role in conditions including cardiovascular disease; type 2 diabetes; Alzheimer's disease; osteoporosis and some cancers.

    We report findings from an analysis of 234 firm boundary decisions that a manufacturing firm has made during a 10 year period. Extensive interviews with all major decision makers located both at the headquarters and subsidiaries allow us to examine (a) who was involved in each boundary decision......, and (b) how the firm arrived at a particular transactional choice in each decision. We find that decision makers extensively adapt decision structures in order to effectively make governance mode choices. They adapt hierarchy span, i.e. the number of hierarchical levels involved, and expertise span, i.......e. the number of same-level decision makers with dissimilar knowledge basis. We observe that decision makers heavily rely on varying hierarchy and expertise span in order to improve the quality of the decision outcome. Central to the adaption of decision structures is that decision makers, over time...

    Vitamin D is an essential hormone for calcium gut absorption. It is also involved in child growth, cancer prevention, immune system responses, and tooth formation. Due to inadequate vitamin D intake and/or decreased sunlight exposure, vitamin D deficiency has resurfaced in developed countries despite known inexpensive and effective preventive methods. Vitamin D deficiency is a common cause of rickets, a condition that affects bone development in children and that can have serious dental complications. Deficiency during pregnancy can cause enamel hypoplasia of primary teeth. Enamel regeneration is currently impossible; hypoplasia is therefore irreversible, and once affected, teeth are prone to fast caries development. Deficiency during early childhood can affect permanent teeth and ensuing caries can sometimes lead to tooth loss at a young age. Oral manifestations of rickets should be diagnosed early by both physicians and dentists to prevent severe dental complications. This case study presents 2 young girls with rickets in early childhood who suffered from subsequent serious tooth decay.

  3. Zinc and childhood infections: From the laboratory to new treatment recommendations

    Full Text Available Zinc is an essential nutrient particularly important for growing children and for those who experience frequent infections. Many children in developing countries have inadequate zinc nutrition that impairs their immune system. Diarrhea and pneumonia are among the leading causes of morbidity and mortality in children of low-income countries. Zinc deficiency increases the susceptibility to these infections and administration of zinc to children with diarrhea and, possibly, pneumonia speeds up recovery. Furthermore, zinc given to otherwise healthy children also reduces the incidence of diarrhea and pneumonia. Thus, thousands of lives can be saved every year by giving zinc to prevent childhood infections or by providing zinc to children with ongoing infections. This paper gives a brief outline of the history of zinc research and reviews existing evidence from clinical trials on the prophylactic and therapeutic effect of oral zinc on childhood pneumonia and diarrhea

    Childhood immunizations are invaluable in preventing contagious diseases. Nonetheless, vaccines have become increasingly controversial with growing numbers of caregivers refusing to vaccinate their children. The percentage of fully vaccinated children in Vermont is one of the lowest nationally. This study set out to determine Vermont caregivers' attitudes toward immunizations to better explain why the percentage of fully vaccinated children has fallen in Vermont. A survey regarding caregivers' health care knowledge about children, their vaccination concerns, and their children's vaccination status was sent to participants in the Vermont Women, Infants and Children's Program from two districts. In total, 83% (n = 379) of respondents reported their children received all recommended vaccinations for their age. Respondents who considered themselves highly knowledgeable regarding their children's health care and confident about the safety of vaccinations were significantly associated with reporting their children as being current on vaccinations and with their intent to continue vaccinations. Respondents indicated highest concern regarding the safety and number of vaccinations administered during one visit. Primary care providers were indicated as important resources for addressing concerns about vaccinations and health care knowledge of children. The results help to understand low vaccination rates in Vermont and can be used for targeting health campaigns to improve vaccination rates.

    Full Text Available Maternal smoking in pregnancy (MSP is a large modifiable risk factor for pregnancy related mortality and morbidity and also the most important known modifiable risk factor for asthma. This review summarises the effects of MSP throughout infancy, childhood and adolescence with regards to asthma (development and severity. Firstly, the direct damage caused by nicotine on fetal lung development, fetal growth and neuronal differentiation is discussed, as well as the indirect effects of nicotine on placental functioning. Secondly, the effects of MSP on later immune functioning resulting in increased infection rate are summarised and details are given on the effects of MSP modulating airway hyperreactivity, reducing lung function and therefore increasing asthma morbidity. Furthermore, epigenetic effects are increasingly being recognised. These can also result in transgenerational detrimental effects induced by cigarette smoke. In summary, the causal relationship between MSP and asthma development is well documented and presents a major health problem for generations to come. The high prevalence of MSP is alarming and epigenetic effects of nicotine on immune functioning potentiate this danger. A considerable part of the increase in asthma prevalence worldwide is due to MSP.

    Numerous studies find a cumulative effect of different types of childhood adversities on increasing risk for serious adult mental and medical outcomes. This study uses the National Comorbidity Survey-Replication sample to investigate the cumulative impact of 8 childhood adversities on complex adult psychopathology as indexed by (a) number of lifetime diagnoses according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed., DSM-IV; American Psychiatric Association, 1994); (b) number of 4 DSM-IV disorder categories (mood, anxiety, impulse control, and substance abuse disorders); and (c) coexistence of internalizing and externalizing disorders. Seven of the 8 childhood adversities were significantly associated with complex adult psychopathology. Individuals with 4 or more childhood adversities had an odds ratio of 7.3, 95% confidence interval [4.7, 11.7] for 4 disorder categories. Additive and multiplicative synergistic effects increasing adult psychopathology were found for specific pairwise combinations of childhood adversities. Synergistic patterns differed by gender suggesting that women are more impacted by sexual abuse and men by economic hardship. The absence of childhood adversities was protective, in that it significantly decreased an individual's risk for subsequent adult mental illness. The results support the clinical impression that increased childhood adversity is associated with more complex adult psychopathology.

    Full Text Available Objective. Suicide is one of the causes of late mortality among childhood cancer survivors. The aim of our study was to analyse the risk of suicide among childhood cancer survivors compared with that ofthe general population of Slovenia. Patients and methods. This retrospective study included patients with childhood cancer registeredat the Cancer Registry of Slovenia between 1978-2008, with an observation period of 1978-2010. Childhood cancer patients and controlsubjects from the general population of Slovenia were matched by sex,year and age at the beginning of follow-up and time of follow-up inyears. Data on the general population of Slovenia were obtained fromthe Statistical Office of the Republic of Slovenia. Results. A total of 1647 patients were recorded in the Cancer Registry as having cancerduring childhood, with 3 patients committing suicide. All three weremale. Their age at diagnosis of cancer was 12, 13 and 2 years old; their age at suicide was 19, 32 and 28 years old. The mechanism of death was asphyxiation in all three deaths. The calculation of the expected number of suicides in the group of individuals with childhood cancer from the general Slovene population revealed the number of 3.16persons. Conclusion. The comparison of the observed and expectedprobability showed that there was no statistically significant difference in the suicide rate between childhood cancer survivors and the general population of Slovenia.

  8. Decisions and desire.

    When we make decisions, we're not always in charge. One moment we hotheadedly let our emotions get the better of us; the next, we're paralyzed by uncertainty. Then we'll pull a brilliant decision out of thin air--and wonder how we did it. Though we may have no idea how decision making happens, neuroscientists peering deep into our brains are beginning to get the picture. What they're finding may not be what you want to hear, but it's worth listening. We have dog brains, basically, with human cortexes stuck on top. By watching the brain in action as it deliberates and decides, neuroscientists are finding that not a second goes by that our animal brains aren't conferring with our modern cortexes to influence their choices. Scientists have discovered, for example, that the "reward" circuits in the brain that activate in response to cocaine, chocolate, sex, and music also find pleasure in the mere anticipation of making money--or getting revenge. And the "aversion" circuits that react to the threat of physical pain also respond with disgust when we feel cheated by a partner. In this article, HBR senior editor Gardiner Morse describes the experiments that illuminate the aggressive participation of our emotion-driven animal brains in decision making. This research also shows that our emotional brains needn't always operate beneath our radar. While our dog brains sometimes hijack our higher cognitive functions to drive bad, or at least illogical, decisions, they play an important part in rational decision making as well. The more we understand about how we make decisions, the better we can manage them.

  9. Positive emotions: A psychological tool for promoting resilience process in childhood

    Carolina Greco

    2015-09-01

    Full Text Available The aim of this theoretical work is to assess the relation between the capacity to experiment positive emotions and the process of resilience throughout childhood. Our interest arises from two research works being carried out in the province of Mendoza, in Argentina (INCIHUSA-CRICYT-CONICET, directed by Dr Mirta Ison. One the so called “Assessment of resilience in childhood maltreatment”, and the other “ Positive emotions as psycological tools for fostering mental health throughout childhood within vulnerable social contexts”. Resilience is always associated to risky or vulnerable social situations. Positive emotions constitute a resource favorable to the development of resilience. This working hypothesis is based on previous studies which hold that positive emotions favor creative thinking for the solution of interpersonal problems, promote cognitive flexibility, reduce risks at decision making, promote replies to generosity and altruism, increase intelectual resources and counteract depressive tendencies among others. Other authors support the fact that the features a resilient child holds are closely connected to cognitive flexibility, to creative capacity, to the capacity for solving interpersonal problems, to self esteem and attachment links among others. Thus, positive emotions are believed to be one of the psycological resources and tools needed for the development of resilience throughout childhood

Utilizaram-se três fontes de informações: registros do Sistema Municipal de Informação em Saúde, carteira de vacinação e entrevista, mediante questionário fechado. As famílias entrevistadas estavam em fase de “maturação” de crescimento, com proles de um ou dois filhos; os cuidadores eram, na maioria, mães jovens, economicamente inativas e havia facilidade de acesso ao serviço de saúde. Cerca de 30% não receberam orientação sobre a vacina aplicada, reações e retorno da próxima vacina. Os maiores atrasos foram das vacinas contra o sarampo (6,3% e o Haemophilus influenzae tipo B (4,2%. Observa-se que o motivo do atraso vacinal e a não-vacinação parecem estar mais relacionados a características do serviço do que às da populaçãoThe aim of this study was to describe and analyze individual and family characteristics of children and those of health services, as well as their relationship with the immunization status for different kinds of vaccines and doses. Three sources of information were used: records from the Municipal Health Information System, immunization charts, and interviews using closed-ended questions. The families interviewed still had one or two growing children; caretakers were usually young unemployed mothers with easy access to health services. Around 30% of them were not instructed on the vaccine being given, its reactions or when to return for the next shot. The greatest levels of tardiness occurred with the vaccines against measles (6.3% and Haemophilus influenzae B (4.2%. It was possible to observe that tardiness or absence of vaccinations seem to have a stronger relationship with service characteristics than with population characteristics

    Acute hepatitis due to hepatitis A virus is usually a benign selflimiting disease during childhood. Although many viral infections such as hepatitis B virus, Parvovirus, and Epstein-Barr virus are associated with extrahepatic autoimmune phenomena, such manifestations are rare in patients with acute hepatitis A infection. Immune thrombocytopenia is a benign, self-limiting disease in children, responding well to treatment and generally associated with viral infections. Immune thrombocytopenic purpura is rarely reported as a manifestation of acute hepatitis A. We report a five-year-old boy with immune thrombocytopenic purpura as the sole manifestation of anicteric acute hepatitis A infection. Acute hepatitis A should be included in the differential diagnosis of immune thrombocytopenic purpura.

The present study examined the relationship between different forms of childhood adversity and laboratory measures of pain. Heat pain tolerance and perceived heat pain intensity were measured in a community-based sample of 62 women (aged 20–64 years. Participants completed the Childhood Trauma Questionnaire (CTQ, which assesses five forms of childhood adversity: physical abuse, sexual abuse, emotional abuse, physical neglect, and emotional neglect. Somatic symptoms, depressive symptoms, and pain catastrophizing were assessed as potential mediators. Bivariate analyses indicated that emotional abuse but no other forms of childhood adversity were significantly related to decreased heat pain tolerance (r=-0.27; P<0.05. Accordingly, multiple regression analyses revealed that only emotional abuse was a significant predictor of heat pain tolerance (β=-0.62; P=0.034 when entering all CTQ subscales simultaneously. Although emotional abuse was also related to somatic symptoms, depressive symptoms, and pain catastrophizing, none of these variables mediated the relationship between childhood adversity and laboratory pain (P>0.1. No significant associations were found between any forms of childhood adversity and heat pain intensity. Our findings indicate that the severity of emotional childhood abuse is associated with decreased pain tolerance, an affective component of pain, but not with heat pain intensity, which has been described as a sensory component of pain.Keywords: childhood adversity, emotional abuse, pain tolerance, pain intensity, somatic symptoms

    Full Text Available This paper presents some characteristics and dilemmas of collective decision making. Collective decision making could be presented as the process of successive crystallization of dominant alternatives under the influence of different decision contexts from primary given decision potentials. This process is presented as the many-phased process of the acting of contextually dependent “energizing factors” of the collective decision making on the “attractiveness matrix” of outcomes of collective decisions. The attractiveness matrix determines the attractiveness for each alternative of decision, and the most attractive alternative in the given situation presents the rational decision in the given situation. In the final phase of decision making holds a context which gets a simplified attractiveness matrix. It corresponds to the common decision for one of the alternatives.

    Full Text Available Abstract Childhood obesity has reached epidemic levels in developed countries. Twenty five percent of children in the US are overweight and 11% are obese. Overweight and obesity in childhood are known to have significant impact on both physical and psychological health. The mechanism of obesity development is not fully understood and it is believed to be a disorder with multiple causes. Environmental factors, lifestyle preferences, and cultural environment play pivotal roles in the rising prevalence of obesity worldwide. In general, overweight and obesity are assumed to be the results of an increase in caloric and fat intake. On the other hand, there are supporting evidence that excessive sugar intake by soft drink, increased portion size, and steady decline in physical activity have been playing major roles in the rising rates of obesity all around the world. Consequently, both over-consumption of calories and reduced physical activity are involved in childhood obesity. Almost all researchers agree that prevention could be the key strategy for controlling the current epidemic of obesity. Prevention may include primary prevention of overweight or obesity, secondary prevention or prevention of weight regains following weight loss, and avoidance of more weight increase in obese persons unable to lose weight. Until now, most approaches have focused on changing the behaviour of individuals in diet and exercise. It seems, however, that these strategies have had little impact on the growing increase of the obesity epidemic. While about 50% of the adults are overweight and obese in many countries, it is difficult to reduce excessive weight once it becomes established. Children should therefore be considered the priority population for intervention strategies. Prevention may be achieved through a variety of interventions targeting built environment, physical activity, and diet. Some of these potential strategies for intervention in children can be

    Myers, W A

    1979-01-01

    Case material is presented to illustrate the thesis that the ability to create an imaginary companion during childhood is an early expression of the special ego aptitudes found in creative individuals in adult life. Such "companions" allow these children to attempt to master creatively a variety of narcissistic mortifications suffered in reality and to displace unacceptable affects. In creative adults who had imaginary companions in childhood, the early fantasies serve as an organizing schema in memory for the childhood traumata. Stimuli in adult life which evoke the earlier traumata may revive the original imaginary companion fantasies. These then serve as nodal bases for the creation of specific adult works of art.

    Clinical decision support (CDS) systems can support vaccine forecasting and immunization reminders; however, immunization decision-making requires data from fragmented, independent systems. Interoperability and accurate data exchange between immunization information systems (IIS) is an essential factor to utilize Immunization CDS systems. Service oriented architecture (SOA) and Health Level 7 (HL7) are dominant standards for web-based exchange of clinical information. We implemented a system based on SOA and HL7 v3 to support immunization CDS in Iran. We evaluated system performance by exchanging 1500 immunization records for roughly 400 infants between two IISs. System turnaround time is less than a minute for synchronous operation calls and the retrieved immunization history of infants were always identical in different systems. CDS generated reports were accordant to immunization guidelines and the calculations for next visit times were accurate. Interoperability is rare or nonexistent between IIS. Since inter-state data exchange is rare in United States, this approach could be a good prototype to achieve interoperability of immunization information.

  3. Bayes Multiple Decision Functions

    CERN Document Server

    Wu, Wensong

    2011-01-01

    This paper deals with the problem of simultaneously making many (M) binary decisions based on one realization of a random data matrix X. M is typically large and X will usually have M rows associated with each of the M decisions to make, but for each row the data may be low dimensional. A Bayesian decision-theoretic approach for this problem is implemented with the overall loss function being a cost-weighted linear combination of Type I and Type II loss functions. The class of loss functions considered allows for the use of the false discovery rate (FDR), false nondiscovery rate (FNR), and missed discovery rate (MDR) in assessing the decision. Through this Bayesian paradigm, the Bayes multiple decision function (BMDF) is derived and an efficient algorithm to obtain the optimal Bayes action is described. In contrast to many works in the literature where the rows of the matrix X are assumed to be stochastically independent, we allow in this paper a dependent data structure with the associations obtained through...

    There is in vitro and in vivo evidence to suggest that dietary lipids play a role in modulating immune function. A review of the current literature on the interrelationships among dietary lipids, blood cholesterol levels, immunosuppression, and tumorigenesis makes for a very strong argument that (a) immunosuppression may be causally related to lymphoproliferative disorders, as well as to tumorigenesis and (b) diets high in polyunsaturated fat, relative to diets high in saturated fat, are more immunosuppressive and are better promotors of tumorigenesis. The effects of dietary fat on immune function seem to be mediated though its component parts, the unsaturated fatty acids, specially linoleic, linolenic, and arachidonic. It is not clear how these components affect immune function. Several studies suggest that one effect is mediated by altering the lipid component of the cell membrane and thus its fluidity; the more fluid the membrane, the less responsive it is. Thus, fluidity of both immune cells and those to be destroyed or protected may be affected. The effects of saturated as well as unsaturated fatty acids may be mediated by modulating serum lipoprotein levels, prostaglandin metabolism, and cholesterol concentrations and metabolism.

    Photodynamic Therapy (PDT) is accepted for treatment of superficial and lumen-occluding tumors in regions accessible to activating light and is now known to be effective in closure of choroidal neovasculature in Age Related Macular Degeneration. PDT utilizes light absorbing drugs (photosensitizers) that generate the localized formation of reactive oxygen species after light exposure. In a number of systems, PDT has immunomodulatory effects; Photodynamic Immune Modulation (PIM). Using low- intensity photodynamic regimens applied over a large body surface area, progression of mouse autoimmune disease could be inhibited. Further, this treatment strongly inhibited the immunologically- medicated contact hypersensitivity response to topically applied chemical haptens. Immune modulation appears to result from selective targeting of activated T lymphocytes and reduction in immunostimulation by antigen presenting cells. Psoriasis, an immune-mediated skin condition, exhibits heightened epidermal cell proliferation, epidermal layer thickening and plaque formation at different body sites. In a recent clinical trial, approximately one-third of patients with psoriasis and arthritis symptoms (psoriatic arthritis) displayed a significant clinical improvement in several psoriasis-related parameters after four weekly whole-body PIM treatments with verteporfin. The safety profile was favorable. The capacity of PIM to influence other human immune disorders including rheumatoid arthritis is under extensive evaluation.

    Full Text Available Introduction Immune recovery vitritis (IRV is symptomatic vitritis of > 1+ severity associated with inactive cytomegalovirus (CMV retinitis. It is an opportunistic infection of the eye, in the patients who suffer from AIDS, and is treated with a highly active antiretroviral therapy (HAART. As a result of this therapy, there is an immune reconstitution in the body and inflammation of the vitreous body. Objective The aim of the study was to show the incidence of IRV in patients treated with HAART. Method A retrospective study was conducted in patients who suffered from CMV retinitis. Twenty-one were treated with HAART and had the diagnosis of CMV retinitis, as well. All of them were examined by the same ophthalmologist who peformed slit lamp examination with mydriasis and indirect ophthalmoscopy. Results Nine of 21 patients developed IRV as a complication of HAART, two had cystoid macular edema (CMO. Conclusion CMV retinitis develops when the number of CD4+ T lymphocytes drops below 50/mm3. This results in necrotic retinitis which, if untreated, leads to complete loss of vision. With the introduction of HAART, we learned that the reconstitution of immune status was achieved as well as life expectancy, but there was a dramatic decline in the opportunistic infection, including CMV retinitis, as well. With the immune reconstitution, the inflammation develops in the eye, known as IRV. Sometimes, it is necessary to treat this condition, but in the case of our patients, the inflammation was mild, and no treatment was necessary.

    While the cellular origin of lymphoma is often characterized by chromosomal translocations and other genetic aberrations, its growth and development into a malignant neoplasm is highly dependent upon its ability to escape natural host defenses. Neoplastic cells interact with a variety of non-malignant cells in the tumor milieu to create an immunosuppressive microenvironment. The resulting functional impairment and dysregulation of tumor-associated immune cells not only allows for passive growth of the malignancy but may even provide active growth signals upon which the tumor subsequently becomes dependent. In the past decade, the success of immune checkpoint blockade and adoptive cell transfer for relapsed or refractory lymphomas has validated immunotherapy as a possible treatment cornerstone. Here, we review the mechanisms by which lymphomas have been found to evade and even reprogram the immune system, including alterations in surface molecules, recruitment of immunosuppressive subpopulations, and secretion of anti-inflammatory factors. A fundamental understanding of the immune evasion strategies utilized by lymphomas may lead to better prognostic markers and guide the development of targeted interventions that are both safer and more effective than current standards of care.

    Immune checkpoint regulators are critical modulators of the immune system, allowing the initiation of a productive immune response and preventing the onset of autoimmunity. Co-inhibitory and co-stimulatory immune checkpoint receptors are required for full T-cell activation and effector functions such as the production of cytokines. In autoimmune rheumatic diseases, impaired tolerance leads to the development of diseases such as rheumatoid arthritis, systemic lupus erythematosus, and Sjogren’s...

    Full Text Available Introduction. An adverse event after immunization is a medical incident following the administration of vaccine, which can be connected with vaccine usage. This event could be a reaction to a vaccine component or lapse in vaccine handling, transport and storage or coincidental event. The assessment of severity of this reaction and the decision about prospective permanent contraindications for futher immunization are to be made by the regional expert team for permanent contraindications. This is regulated by low. Case report. A series of adverse events after immunization in three children of a single family is reported. As regulated by law, all three children were vaccinated with different vaccines, from 2007. to 2010. Although the recorded events were diverse by their nature, way of clinical manifestation and severity they all required hospitalization. In addition to being siblings, the three children had the same atopic diseases in their personal and family anamnesis. All adverse events were explored including allergological/immunological tests. Thanks to the good cooperation of involved general practicioners, pediatricians, members of expert team for permanent contraindications and clinicians, two of three children received the full series of vaccines in optimal time. Discussion. Decision making about futher immunization of children with adverse event after vaccine administration depends on the nature and severity of developed medical condition, results of medical exploration, existing immunity and personal risk of getting disease and subsequent complications. Conclusion. Bearing in mind the significance of immunization for personal and collective immunity, good cooperation of all physicians and experts involved in each single case of adverse event is required.

  13. Maternal immune transfer in mollusc.

    Maternal immunity refers to the immunity transferred from mother to offspring via egg, playing an important role in protecting the offspring at early life stages and contributing a trans-generational effect on offspring's phenotype. Because fertilization is external in most of the molluscs, oocytes and early embryos are directly exposed to pathogens in the seawater, and thus maternal immunity could provide a better protection before full maturation of their immunological systems. Several innate immune factors including pattern recognition receptors (PRRs) like lectins, and immune effectors like lysozyme, lipopolysaccharide binding protein/bacterial permeability-increasing proteins (LBP/BPI) and antioxidant enzymes have been identified as maternally derived immune factors in mollusc eggs. Among these immune factors, some maternally derived lectins and antibacterial factors have been proved to endue mollusc eggs with effective defense ability against pathogen infection, while the roles of other factors still remain untested. The physiological condition of mollusc broodstock has a profound effect on their offspring fitness. Many other factors such as nutrients, pathogens, environment conditions and pollutants could exert considerable influence on the maternal transfer of immunity. The parent molluscs which have encountered an immune stimulation endow their offspring with a trans-generational immune capability to protect them against infections effectively. The knowledge on maternal transfer of immunity and the trans-generational immune effect could provide us with an ideal management strategy of mollusc broodstock to improve the immunity of offspring and to establish a disease-resistant family for a long-term improvement of cultured stocks.

    In France, cancer hits around 1700 children (0-14 years) each year. The age-standardized incidence rate for all cancers combined is 152 cases per million children per year, with a sex ratio of 1.2. In other terms, one child out of 440 develops a cancer before the age of 15 in industrial countries. The most frequent cancers were leukaemia (29%), embryonal tumours apart central nervous system (25%), central nervous system tumour (23%) and lymphoma (12%). The incidence varies between countries with higher overall rates in industrialized countries. These variations may reflect differences in diagnostic techniques or registration or in the distribution of possible risk factors. Five-year survival after childhood cancer has dramatically improved in the last 30 years, reaching yet 80%.

    This was a retrospective study to determine different etiologies of cerebral venous thrombosis (CVT) in childhood and to correlate extent and location of thrombosis with the etiology and the age of the child as well as the final outcome. In addition, the radiologic approach is discussed. This was a retrospective analysis of 19 children with CVT. The children were examined by contrast-enhanced dynamic CT. Radiologic findings were correlated with the etiology of CVT. Cerebral venous thrombosis is not as infrequent in children as has been thought. Cerebral venous thrombosis in children can occur due to trauma (n=9), infections (n=7), or coagulation disorders (n=3). Extent and location of thrombosis, as well as complications, final outcome, and therapy, depend on the etiology. Computed tomography remains a valuable primary imaging modality in the diagnosis of CVT in the acutely injured or diseased child. (orig.)

    The patogenesis and etiology of acute ataxia in childhood is not well known. It may occur without previous symptoms or may be the expression of specific infectious diseases. Forty patients hospitalized at the Hospital de Niños de Buenos Aires en 1972-1978, were studied. The neurological manifestations showed an acute onset, being ataxia the main sign, associate to tremor, nystagmus, dysartria, oculo-motor paresia, muscular weakness, and hyporeflexia. Most of the patients (82%) became cured within the first four weeks. It is advisable to establish a follow-up with periodic controls, mainly in those patients in whom an association with previous infectious diseases did not exist to be able to detect an association with degenerative or desmyelinizing diseases.

    Obesity in childhood is one of the major health issues in pediatric health care today. As expected, the prevalence of obesity-related comorbidities has risen in parallel with that of obesity. Consultation regarding these concomitant diseases and subsequent management by subspecialists, including pediatric gastroenterologists, is now common and has resulted in obesity being recognized as a chronic disease requiring coordination of care. Although medications and even surgery may provide effective, though often temporary, treatments for obesity and its comorbidities, behavioral interventions addressing healthy dietary and physical activity habits remain a mainstay in the obesity treatment paradigm. Therefore, the issue of weight management must be addressed by both general practitioner and subspecialist alike. In this report, we review select aspects of pediatric obesity and obesity-related management issues because it relates in particular to the field of pediatric gastroenterology and hepatology.

    Gamstorp, I

    1990-01-01

    Personal experience of 30 years work with 40-50 cases of dermatomyositis and polymyositis in childhood is reviewed, stressing the clinical findings of skin eruptions on the knuckles, elbows and knees (except in the 10 per cent of patients without any skin involvement), weakness of particularly proximal muscles and tightness of tendons. Special diagnostic procedures are reviewed as well as treatment. The basic treatment is corticosteroids, which must be started at a high dose and as soon as possible be given at intervals of 48 hours to diminish the side-effects. In many, though not all, patients the treatment must be continued for years. The parents should always know that extended treatment may be necessary. Physiotherapy should be started cautiously and be slowly increased, close co-operation between the physician and the physiotherapist being necessary. If the patient does not respond to corticosteroids, antimetabolites may be added. Most patients survive with no or only minor sequelae.

  19. Bejel: acquirable only in childhood?

    Bejel clearly has a long history in the Middle East and the Sudan, but was it transmitted to Europe? As the major manifestation of bejel is presence of periosteal reaction in 20-40% of afflicted populations, absence of significant population frequency of periosteal reaction in Europe would exclude that diagnosis. Examination of skeletal populations from continental Europe revealed no significant periosteal reaction at the time of and immediately subsequent to the Crusades. Thus, there is no evidence for bejel in Europe, in spite of clear contact (the mechanism of bejel transmission in children) between warring groups, at least during the Crusades. This supports the hypothesis that bejel is a childhood-acquired disease and apparently cannot be contracted in adulthood.
