  1. Children's exposure to diagnostic medical radiation and cancer risk: epidemiologic and dosimetric considerations

    International Nuclear Information System (INIS)

    While the etiology of most childhood cancers is largely unknown, epidemiologic studies have consistently found an association between exposure to medical radiation during pregnancy and risk of childhood cancer in offspring. The relation between early life diagnostic radiation exposure and occurrence of pediatric cancer risks is less clear. This review summarizes current and historical estimated doses for common diagnostic radiologic procedures as well as the epidemiologic literature on the role of maternal prenatal, children's postnatal and parental preconception diagnostic radiologic procedures on subsequent risk of childhood malignancies. Risk estimates are presented according to factors such as the year of birth of the child, trimester and medical indication for the procedure, and the number of films taken. The paper also discusses limitations of the methods employed in epidemiologic studies to assess pediatric cancer risks, the effects on clinical practice of the results reported from the epidemiologic studies, and clinical and public health policy implications of the findings. Gaps in understanding and additional research needs are identified. Important research priorities include nationwide surveys to estimate fetal and childhood radiation doses from common diagnostic procedures, and epidemiologic studies to quantify pediatric and lifetime cancer risks from prenatal and early childhood exposures to diagnostic radiography, CT, and fluoroscopically guided procedures.

    Full Text Available Schistosomiasis remains a public health major problem and little is known in many areas, mainly in Sub-Saharan Africa.To assess the burden and risk factors of schistosomiasis and intestinal parasitic helminthes in the children of Cubal, Angola, and to compare different diagnostic approaches for urinary schistosomiasis under field conditions.A cross-sectional study was conducted. Urine and faeces samples of school children were microscopically studied. A random sample of children was obtained from an alphabetically arranged list of children, taking one of two children. Urine dipstick, colorimetric test and macrohaematuria were considered as indirect diagnostic methods and compared to direct urine examination. Possible risk factors for the infection were sex, age, distance to the river and previous treatment with praziquantel; the assessment was performed using Chi-square test.A total of 785 (61.18% children showed S. haematobium eggs in urine; children living within 500 meters from the river had a higher odds for infection: Odds ratio 1.97 (1.45-2.7 CI 95%; urine dipstick showed sensitivity of 96% and specificity of 61.3%, with a positive predictive value; colorimetric test showed sensitivity of 52.5%, specificity of 74.6% and a positive predictive value of 77%. Proteinuria was present in 653 (51.1% children, being more frequent in children with S. haematobium in urine (75.2%; 32 of 191 stool samples (16% showed the presence of other intestinal parasites and 8 (4% for S. haematobium.Prevalence of urinary schistosomiasis in our study area is much higher than the national average, considering it as a high-risk community. Proximity to a source of water was a risk factor for the infection. Indirect tests, as urine dipstick and colorimetric test, were useful tools for diagnosis, due to ease of use and low cost. Proteinuria was a common finding, probably showing an early structural damage due to schistosomiasis in this group of children.

    Full Text Available Malignant catarrhal fever (MCF is a frequently fatal disease, primarily of ruminants, caused by a group of gammaherpesviruses. Due to complexities of pathogenesis and epidemiology in various species, which are either clinically-susceptible or reservoir hosts, veterinary clinicians face significant challenges in laboratory diagnostics. The recent development of specific assays for viral DNA and antibodies has expanded and improved the inventory of laboratory tests and opened new opportunities for use of MCF diagnostics. Issues related to understanding and implementing appropriate assays for specific diagnostic needs must be addressed in order to take advantage of molecular diagnostics in the laboratory.

    Celiac disease is induced by the consumption of gluten containing cereals (wheat, spelt, barley, rye). With a prevalence of ~ 1 %, it is the most common non-infectious chronic inflammatory intestinal disease worldwide. It manifests in all age groups, either classically with abdominal pain, diarrhoea and growth failure or weight loss, more commonly with indirect consequences of malabsorption, such as anaemia and osteoporosis, or with associated autoimmune diseases like type 1 diabetes, autoimmune thyroiditis or dermatitis herpetiformis. The pathogenesis of celiac disease is well explored. Gluten, the cereal storage protein, is not completely digested and reaches the intestinal mucosa where it activates inflammatory T cells, which cause atrophy of the resorptive villi. This T‑cell activation requires a genetic predisposition (the molecules HLA-DQ2 or -DQ8 on antigen-presenting immune cells). Moreover, the enzyme tissue transglutaminase (TG2) which is released in the mucosa increases the immunogenicity of the gluten peptides by a deamidation reaction. The test for serum antibodies to the autoantigen TG2 is one of the best diagnostic markers in medicine, which in combination with endoscopically obtained biopsies, secures the diagnosis of celiac disease. Despite these tools celiac disease is severely underdiagnosed, with 80-90 % of those affected being undetected. The untreated condition can lead to grave complications. These include the consequences of malabsorption, cancers (especially intestinal T‑cell lymphoma), and likely also the promotion of autoimmune diseases. The therapy of celiac disease, a strict gluten-free diet, is difficult to maintain and not always effective. Alternative, supporting pharmacological therapies are urgently needed and are currently in development. PMID:27273303

  9. Evaluation of diagnostic tools for epidemiological purposes: Application to FMD

    International Nuclear Information System (INIS)

    Full text: Foot-and-mouth disease (FMD) is economically the most important disease of domestic livestock. Due to its highly infectious nature, ability to cause persistent infection and long-term effects on the animal species it affects, countries that have the disease have many trade restrictions placed upon them. The importance of laboratory information is critical for FMD control and eradication programs. In this regard and in support of the Continental Program for Eradication of FMD, implemented in 1988 in the Americas, a major challenge for the Pan American Foot-and-Mouth Disease Center (PAFMDC) as a regional OIE reference laboratory, was related to the adaptation of approaches to respond to the new demands of diagnostic precision placed to support the epidemiological transition expected in the Continent. Regions with advanced eradication campaigns needed to incorporate approaches for rapid and precise identification of the agent during an emergency, and equally important, for enabling a deeper epidemiological analysis, capable of characterizing the potential sources of infection and dissemination of the virus, either during clinical or subclinical viral circulation. Since the implementation of the eradication program there have been significant advances in the understanding of FMD epidemiology in South America. These have partly been due to the application of nucleotide sequencing methods for viral characterization and of newly developed tools for sero epidemiological monitoring of persistent viral activity, based on the use of recombinant noncapsideal antigens as serological probes to detect infection specific antibodies, regardless of vaccination condition. In the PAFMDC, a genetic sequence database of representative South American strains has been built up, which constituted the basis for the phylogenetic analysis of the viruses type O and A, responsible for the major outbreaks recorded, in regions already declared free by the OIE in the Southern Cone of

    A retrospective epidemiological and diagnostic study of visceral leishmaniasis (VL) was carried out during the period 2001-2007 and included patients suspected of VL who had been diagnosed at the Parasitological Laboratory at the Institute for Infectious and Tropical Diseases, Belgrade. Diagnosis of VL was confirmed by microscopic examination of Giemsa-stained bone marrow (BM) smears. BM smears from 134 patients were examined; 22 cases of VL were diagnosed, the majority of which involved individuals who had been on holiday at the Montenegrian sea coast. The sensitivity of the initial BM smears was inadequate; this required the application of a serological test, adapted for routine use, for the diagnosis of VL. PMID:19392902

  11. Proposed motor development assessment protocol for epidemiological studies in children.

    2009-01-01

    This paper proposes an approach to the implementation of a large-scale epidemiological study of child development. It addresses specifically how one might assess gross motor development longitudinally in a large population-based study of children, and recommends a three-phase process. Phase I, applied at key ages with the entire population, involves the use of parent-report screening tools that ask about specific age-appropriate motor skills, as well as any parental concerns about "quantity" or "quality" of their child's motor function and about any loss of motor function. In phase II, children who "fail" the screening phase (at any stage) are evaluated with specified developmental motor assessments. Those who "pass" revert to the screening stream, while those who "fail" continue to phase III. In this third component of the study, children are referred to experts in child development formally engaged in the study (including developmental paediatricians, paediatric neurologists and developmental therapists). These experts will use protocol-based evaluations to ascertain whether a child has a problem in development, what the problem might be from a diagnostic perspective, how "severe" the problem is, and what management services are or should be provided. It is argued that this is an efficient approach to the study of a population that would enable investigators to detect specific relatively common developmental motor disorders (in particular, cerebral palsy and developmental coordination disorder).

  12. Evaluation of diagnostic tools for epidemiological purposes - Application to FMD

    International Nuclear Information System (INIS)

    Since the implementation in 1988 of the foot-and-mouth disease (FMD) eradication programme in South America (PHEFA), significant advances have been made in the control of the disease. Particularly relevant has been the progress attained in one of the three subregions, the Southern Cone, where during the late 1990s most areas were recognized as FMD-free by OIE, with or without vaccination. To achieve PHEFA goals, development and implementation of diagnostic tools to trace for potential sources of infection was of utmost importance. Accordingly, priority was given to the identification of genetic links among circulating strains and, in relevant areas, to the systematic sero-epidemiological monitoring of persistent viral activity, regardless of vaccination condition. A genetic database of representative strains from South America, constructed at the Pan American Foot-and-Mouth Disease Center, constituted the basis for the phylogenetic analysis of viruses types 0 and A recorded recently in endemic regions, and during the emergencies in FMD-free areas of the Southern Cone. The genetic data placed all variants from the Southern Cone in a single lineage, which clearly differed from the evolutionary nodes that included the isolates in the Andean subregion, reflecting two independent production systems and livestock trade circuits. To complement the search for potential sources of infection, serosurveillance became an important adjunct. To this end, new tools to infer viral circulation within and between herds, irrespective of vaccination, were developed and validated. The diagnostic approach, based on an immuno-enzymatic system that detects antibodies against non-capsid proteins, was particularly useful in support of epidemiological investigations after episodes and to confirm absence of viral activity in regions to be recognized as FMD-free, being especially important prior to the suspension of vaccination.

    Orally transmitted Chagas disease has become a matter of concern due to outbreaks reported in four Latin American countries. Although several mechanisms for orally transmitted Chagas disease transmission have been proposed, food and beverages contaminated with whole infected triatomines or their faeces, which contain metacyclic trypomastigotes of Trypanosoma cruzi, seems to be the primary vehicle. In 2007, the first recognised outbreak of orally transmitted Chagas disease occurred in Venezuela and largest recorded outbreak at that time. Since then, 10 outbreaks (four in Caracas) with 249 cases (73.5% children) and 4% mortality have occurred. The absence of contact with the vector and of traditional cutaneous and Romana’s signs, together with a florid spectrum of clinical manifestations during the acute phase, confuse the diagnosis of orally transmitted Chagas disease with other infectious diseases. The simultaneous detection of IgG and IgM by ELISA and the search for parasites in all individuals at risk have been valuable diagnostic tools for detecting acute cases. Follow-up studies regarding the microepidemics primarily affecting children has resulted in 70% infection persistence six years after anti-parasitic treatment. Panstrongylus geniculatus has been the incriminating vector in most cases. As a food-borne disease, this entity requires epidemiological, clinical, diagnostic and therapeutic approaches that differ from those approaches used for traditional direct or cutaneous vector transmission.

    2004-07-01

    Brenner et al (2001) reported that estimates of the exposure to children from CT scans indicates that the exposures are both higher than from conventional radiographic studies and higher than is necessary to obtain quality examinations. utilizing the oncogenic risk data from the RERF study in Japan, Brenner et al estimated that the oncogenic risk in this population of CT exposed children exposed each year would result in an additional 500 cases of cancer. This risk estimate is supported by the RERF epidemiological data obtained from the populations exposed in Hiroshima and Nagasaki. the increased risks associated with the increased exposure from CT scans have raised concern and stimulated discussion. Although there is little doubt about the benefits of CT scans in improving the health care of children, there is concern about the estimated oncogenic risk, especially since the frequency of CT studies has been increasing. Applying the oncogenic risks of ionizing radiation from the RERF data may not be appropriate for all types of radiation exposure for accurately predicting the incidence of cancer in exposed children because of the impact of 1) partial versus whole-body irradiation, and 2) the protraction of the exposure. Other population of children who have been exposed to radiation and whose incidence of cancer has been studied will be presented and those studies indicate that the risk of cancer is much lower or not increased at all with exposures in the diagnostic range. finally, the dramatic impact of the use of CT scans in clinical pediatric practice saves lives and improves diagnostic accuracy. Therefore, it is crucial that a scholarly evaluation of the risks and benefits should be initiated. The radiology community and the manufacturers have already initiated programs to decrease the exposure significantly. But it is essential that well-planned, retrospective and prospective epidemiology studies should be initiated to study the oncogenic risks. If you want to

    International Nuclear Information System (INIS)

    Enuresis is a common symptom that leads to significant psychosocialsequalae. In this study we analyzed three surveys in three different urbanand suburban regions in Morocco in order to evaluate the epidemiologicalcharacteristics and profiles of the young patients who had enuresis and theattitudes of their parents towards this problem. There were 1520 children andadolescents in this analysis whose age ranged between 5 and 15 years. Theywere attending various outpatient surgical and medical clinics when theirparents were asked to answer a pre-prepared questionnaire. The prevalence ofenuresis was 35% with preponderance of males (54%). The cause could not bedefined (primary) in 91.5% of the patients with enuresis. There were familialfactors associated with enuresis that included history of enuresis in theparents or siblings in 56% of the cases and coercion attitude of the parentsin 23%. Enuresis was associated with impediment of learning in 23%andchastisement of children in 85.4% of the cases. Twenty-three percent ofpatients also had chronic disorders. The parents were concerned mostly whenthe children approached puberty or when enuresis was secondary to anotherproblem. Spontaneous improvement was the rule by adolescence, hence only 8.7%sought medical advice for enuresis. Treatment was conventional in 67% of thecases and confined to restriction of fluids and food items in 73% of thetreated patients. We conclude that enuresis is apparently higher in Moroccanchildren compared to reports in other countries. However, enuresis was notconsidered a major medical problem of concern to parents who rarely soughtmedical advice for it. (author)

Methods included a retrospective review of data for children birth to 18 years old from the National Electronic Injury Surveillance (NEISS system of the US consumer Product Safety Commission for the years 2005-2009. A total of 5093 cases were identified and would result in an estimated 175,000 injuries in the US. The most common type of injury was a sprain/strain to the ankle (20%. Four out of five injuries were among children between 10 and 18. Injuries occurring at school accounted for 40% of the injuries. Exercise-related injuries are common among older children and often occur in schools or recreational environments but are usually minor. School officials and athletic personnel should make efforts to provide proper instruction on exercise activities and have resources to provide emergency care for injuries.

    Carla Weiblen

    2016-05-01

    Full Text Available ABSTRACT: Conidiobolomycosis is an emerging disease caused by fungi of the cosmopolitan genus Conidiobolus . Particular strains of Conidiobolus coronatus, Conidiobolus incongruus and Conidiobolus lamprauges , mainly from tropical or sub-tropical origin, cause the mycosis in humans and animals, domestic or wild. Lesions are usually granulomatous and necrotic in character, presenting two clinical forms: rhinofacial and nasopharyngeal. This review includes the main features of the disease in sheep, with an emphasis on the epidemiology, clinical aspects, and diagnosis of infections caused by Conidiobolus spp. in Brazil. In this country, the disease is endemic in the Northeast and Midwest, affecting predominantly woolless sheep breeds and occasioning death in the majority of the studied cases. The species responsible for infections of sheep are C. coronatus and C. lamprauges and the predominant clinical presentation is nasopharyngeal. These fungal infections are very important, since they compromise the health status of the sheep flock and cause serious economic losses to the sheep industry. Thus, research is needed to investigate faster tools for diagnosis and effective methods for the control and treatment of conidiobolomycosis.

  6. Musculoskeletal tumours: Epidemiology, clinical signs and diagnostic requirements

    International Nuclear Information System (INIS)

    Muscoloskeletal neoplasms are comparatively rare and the accompanying clinical picture will mostly be rather inconclusive. The basic diagnostic measures taken are first of all aimed at a preliminary differentiation between benign and malignant changes. Should the results suggest the presence of a primary malignoma, further examinations will be needed. Unenhanced X-rays, radionuclides studies, CT and nmr imaging are currently regarded as indispensable for staging and therapy planning. The site of the tumour and its influence on adjacent anatomical structures is of particular importance as regards limb-saving procedures. Any such decision can only be made on the basis of axial as well as coronary nmr images that visualize all of the diseased bone and pertinent joints. Follow-up studies using nmr imaging are only reasonable, if the same sequences and scanning planes are examined throughout. (orig./MG)

The goal of the research was to estimate the prevalence of physical, psychological and sexual violence against children in the family as well as prevalence of feeling of neglect in children. Gender and age differences in the prevalence of violence, as well as differences with respect to geographic region and urbanicity of place of the children’s’ residence were also examined. The stratified cluster sample consisted of 4027 children attending the fifth and seventh grades of the primary school and the second grade of the high school. Data was collected by an adapted version of the questionnaire ICAST-C (ISPCAN Child Abuse Screening Tool-Chidren Version - ICAST-C. At least one experience of psychological violence in the lifetime was reported by 68,4% of children, whereas at least one experience of physical violence was reported by 69,2% of children. Feeling of neglect was experienced by 28.8% of children at least once in their lifetime. At least one experience of sexual violence was reported by 8.5% children, whereas 3,7% of them reported the experience of contact sexual violence in the past year. The results indicate that girls are more exposed to psychological violence and report more feeling of neglect. Conversely, boys report more exposure to sexual violence. The rate of severe forms of physical, psychological and sexual violence is about 0.5 to 1%.

    Leptospirosis is a systemic disease affecting humans and animals, and pigs are generally considered the reservoir host species for the serovars Pomona, Bratislava and Tarrasovi. Endemic infections in swine herds generally remain subclinical, as do the vast majority of leptospire infections. However, when a susceptible breeding herd is infected for the first time or its immunity is compromised, considerable losses can occur due to abortion, stillbirths, weakly piglets or infertility. Infections in pigs caused by other serovars tend to occur only incidentally, vary regionally, and depend on other reservoir hosts, primarily rodents. Leptospires persist in porcine kidneys, and the Bratislava serovar, in the genital tract; it is excreted in urine and genital fluids. Leptospirosis is transmitted by direct or indirect contact with an infected animal. Fundamental research on porcine leptospirosis was conducted in the 1970s and 1980s. However, despite subsequent application of the most recent molecular biological methods, the pathogenesis of porcine leptospirosis is still largely unknown, and research results from the last 25 years on its incidence are very heterogeneous, due not only to regional differences but also to differences in the evaluation of diagnostic and population studies. Serological testing of pigs showed serovar prevalences ranging between as much as 16.3% (Pomona) and generally no more than 2.9% (Tarassovi), whereas antibodies against Bratislava were found in as many as 41.8% of pigs tested during the last 20 years, as in previous studies, indicating that this remains the most prevalent serovar.

    This paper reviews current knowledge of childhood sarcoidosis with regard to the epidemiology in Danes, clinical presentation, diagnostic procedures, treatment and prognosis. Sarcoidosis is a granulomatous disease of unknown aetiology, with multiorgan involvement. The diagnosis is confirmed by the demonstration of epitheloid cell granulomas in tissue biopsy specimens. During the period 1980-92, three cases of childhood sarcoidosis were recorded in Copenhagen County, which has a total population of 610,000. The approximate incidence of clinically recognized sarcoidosis in Danish children younger than 15 y of age was 0.22-0.27/100,000 children per year, corresponding to approximately three new cases in Denmark each year. The true incidence is unknown, since the disease is often asymptomatic and resolves without a clinical diagnosis being made. In children younger than 5 y of age, the disease is characterized by involvement of skin, eyes and joints, whereas in older children involvement of lungs, lymph nodes and eyes predominate. The mainstay of treatment consists of oral corticosteroids. The risk/benefit ratio of using long-term corticosteroids needs to be evaluated in each individual patient. Some patients may benefit from additional therapy with methotrexate. The long-term prognosis is not well established, but it seems to be poorer in children younger than 5 y. Older children appear to have as favourable a prognosis as young adults. PMID:9736236

    Full Text Available In the last years, epidemiological landscape of pediatric illness is changed; we are facing a progressive raising of the number of children affected by chronic illness (children with special health care needs [CSHCN], mainly due to the amelioration in surviving and in care. These patients have become the majority of the inpatients in some specialist hospitals, like the Meyer Children’s Hospital (Florence, Italy, in 2012. One important group of CSHCN is represented by the children who are most medically fragile and have the most intensive health care needs (children with medical complexity [CMC]. In these patients, the complexity of the pathological framework frequently results in a plenty of visits and tests, with high risk of redundant and expensive cares. They also need outside support networks such as advocacy and accommodations at school, at home, in social life. The CMC needs specific skill and new strategies that could involve pediatricians in hospital as in home care. The professional competencies are ready but a clear and shared strategy is lacking. Proceedings of the 10th International Workshop on Neonatology · Cagliari (Italy · October 22nd-25th, 2014 · The last ten years, the next ten years in Neonatology Guest Editors: Vassilios Fanos, Michele Mussap, Gavino Faa, Apostolos Papageorgiou

    Tuberculosis (TB) is one of the leading causes of death worldwide. Over the last decades, TB has also emerged in the pediatric population. Epidemiologic data of childhood TB are still limited and there is an urgent need of more data on very large cohorts. A multicenter study was conducted in 27 pediatric hospitals, pediatric wards, and public health centers in Italy using a standardized form, covering the period of time between 1 January 2010 and 31 December 2012. Children with active TB, latent TB, and those recently exposed to TB or recently adopted/immigrated from a high TB incidence country were enrolled. Overall, 4234 children were included; 554 (13.1%) children had active TB, 594 (14.0%) latent TB and 3086 (72.9%) were uninfected. Among children with active TB, 481 (86.8%) patients had pulmonary TB. The treatment of active TB cases was known for 96.4% (n = 534) of the cases. Overall, 210 (39.3%) out of these 534 children were treated with three and 216 (40.4%) with four first-line drugs. Second-line drugs where used in 87 (16.3%) children with active TB. Drug-resistant strains of Mycobacterium tuberculosis were reported in 39 (7%) children. Improving the surveillance of childhood TB is important for public health care workers and pediatricians. A non-negligible proportion of children had drug-resistant TB and was treated with second-line drugs, most of which are off-label in the pediatric age. Future efforts should concentrate on improving active surveillance, diagnostic tools, and the availability of antitubercular pediatric formulations, also in low-endemic countries. PMID:27322255

    Main problems of system of epidemiologic control for cholera active in Russian Federation, as well as laboratory diagnostics and vaccine prophylaxis of this especially dangerous infection, that had emerged in the contemporary period of the ongoing 7th pandemic of cholera, are discussed. Features of the genome of natural strains of Vibrio cholerae of El Tor biovar, that possess a poten- tial epidemic threat, as well as problems, that have emerged during isolation of these strains from samples of water of surface water bodies during their monitoring, are also examined. The main direction of enhancement of the system of epidemiologic control for cholera consist in develop- ment of a new algorithm of differentiation of administrative territories of Russian Federation by types of epidemic manifestations, as well as optimization of monitoring of environment objects. Integration of modern highly informative technologies into practice, as well as development of new generation diagnostic preparations based on DNA-chips and immunechips is necessary to increase effectiveness of the conducted operative and retrospective diagnostics in the contemporary period. Creation of national cholera vaccine, ensuring simultaneous protection from cholera causative agents of both O1 and O139 serogroups, is also required. PMID:27029123

    Full Text Available Clinical practice has an effective methodology of diagnostic procedures to be followed in cases of sepsis. However, there are as yet no corresponding standards of action in post-mortem diagnostics. The scope of examinations is limited to an autopsy and histopathological tests. This situation may lead to errors in medico-legal opinions on the cause of death and in the assessment of appropriateness of medical procedures. In cases of suspected sepsis, medico-legal investigations require obtaining detailed information about the circumstances of death (including symptoms and results of intravital examinations before autopsy is performed, as well as sterile collection of specimens for microbiological tests and interpretation of their results on the basis of knowledge of epidemiology, pathophysiology and clinical progression of sepsis.

    Introduction: The finding of reduced value of immunoglobulin A (IgA) in children is frequent in daily medical practice. It is important to correctly interpret the findings as adequate further diagnostic evaluation of the patient in order to make the determination on the significance of such findings. In children younger than 4 years always consider the transient impairment of immunoglobulins, maturation of child and his immune system can lead to an improvement in the clinical picture. In older children decreased IgA may lead to serious illnesses that need to be recognize and acknowledge through the appropriate diagnostic methods. At the University Clinical Center Tuzla, children with suspected deficient immune response due to reduced values of IgA, goes through further diagnostic evaluation at the Polyclinic for Laboratory Medicine, Department of Immunology and Department of Microbiology, as well as the Clinic of Radiology. Material and methods: Our study followed 91 patients, for the year 2013, through their medical charts and made evaluation of diagnostic and screening tests. Conclusion: The significance of this paper is to draw attention to the importance of diagnostic approach to IgA deficient pediatric patient and relevance of knowledge of individual diagnostic methods as well as to the proper interpretation of the results thereof.

  20. Radioisotope diagnostics of lung pathology in children by clinical data

    International Nuclear Information System (INIS)

    Analysis of clinical data (118 patients) shows convincingly that radioisotope investigations play an important role in recognition of lung pathology in children. Diagnostic value of the method increases especially in those cases when clinical-roentgenological diagnostics of this pathology turns out to be difficult. Expressiveness of scannographic signs permits to differentiate different forms of lung pathology and alongside with this to observe dynamics of pathological processes in lungs which makes it possible to perform selective therapeutic tactics in either concrete situation

    Ebola virus disease (EVD) is a severe multisystem disease. Prehospital personnel, hospitals, and clinicians must be prepared to provide care for patients with EVD, with special attention to rigorous infection control in order to limit the spread of infection. Children with EVD are an especially challenging population, as the initial symptoms are nonspecific and difficult to differentiate from several common infections. For children presenting with a syndrome consistent with EVD, it is extremely important that healthcare workers identify epidemiologic risk factors, such as recent travel to an affected country or exposure to a patient with suspected or known EVD. Given the high morbidity and mortality of this disease, clinical efforts should focus on early diagnosis, appropriate infection control, and supportive care. PMID:27328168

    Ebola virus disease is caused by a highly contagious and pathogenic threadlike RNA virus of the Filoviridae family. The index human case is usually a zoonosis that launches human-to-human transmission interface with varying levels of sustainability of the epidemic depending on the level of public health preparedness of the affected country and the Ebola virus strain. The disease affects all age groups in the population. Clinical diagnosis is challenging in index cases especially in the early stages of the disease when the presenting features are usually nonspecific and only similar to a flu-like illness. However, in the agonal stages, hemorrhage frequently occurs in a high proportion of cases. The diagnostic gold standard is by detecting the antigen using reverse transcription-polymerase chain reaction. Mortality rates in the past 28 outbreaks since 1976 have ranged from 30% to 100% in different settings among adults, but lower mortality rates have been documented in children. This review aims to describe Ebola virus infection, clinical presentation, diagnosis and outcomes in children. PMID:25522340

    Viral respiratory infections continue to pose a major global healthcare burden. At the community level, the co-circulation of respiratory viruses is common and yet studies generally focus on single aetiologies. We conducted the first comprehensive epidemiological analysis to encompass all major respiratory viruses in a single population. Using extensive multiplex PCR diagnostic data generated by the largest NHS board in Scotland, we analysed 44230 patient episodes of respiratory illness that were simultaneously tested for 11 virus groups between 2005 and 2013, spanning the 2009 influenza A pandemic. We measured viral infection prevalence, described co-infections, and identified factors independently associated with viral infection using multivariable logistic regression. Our study provides baseline measures and reveals new insights that will direct future research into the epidemiological consequences of virus co-circulation. In particular, our study shows that (i) human coronavirus infections are more common during influenza seasons and in co-infections than previously recognized, (ii) factors associated with co-infection differ from those associated with viral infection overall, (iii) virus prevalence has increased over time especially in infants aged population that warrants further investigation.

    Although skeletal scintiscanning has yielded results allowing an early diagnosis of osteomyelitis in children already at a stage prior to detection by X-ray radiography, reports have been published showing that there is quite a number of false negative findings obtained by nuclear medicine techniques, especially in newborns. The article here therefore reports a study on clinical validation of skeletal scintigraphy in case of suspected osteomyelitis in children. The results show that scintiscanning is a very sensitive method of detecting osteomyelitis in children, and also can be a very useful diagnostic tool for examination of newborns, provided the different anatomy of the skeleton in newborns is taken into account.

    Rao, Goutham

    2016-08-01

    National guidelines for the diagnosis and management of hypertension in children have been available for nearly 40 years. Unfortunately, knowledge and recognition of the problem by clinicians remain poor. Prevalence estimates are highly variable because of differing standards, populations, and blood pressure (BP) measurement techniques. Estimates in the United States range from 0.3% to 4.5%. Risk factors for primary hypertension include overweight and obesity, male sex, older age, high sodium intake, and African American or Latino ancestry. Data relating hypertension in childhood to later cardiovascular events is currently lacking. It is known that BP in childhood is highly predictive of BP in adulthood. Compelling data about target organ damage is available, including the association of hypertension with left ventricular hypertrophy, carotid-intima media thickness, and microalbuminuria. Guidelines from both the United States and Europe include detailed recommendations for diagnosis and management. Diagnostic standards are based on clinic readings, ambulatory BP monitoring is useful in confirming diagnosis of hypertension and identifying white-coat hypertension, masked hypertension, and secondary hypertension, as well as monitoring response to therapy. Research priorities include the need for reliable prevalence estimates based on diverse populations and data about the long-term impact of childhood hypertension on cardiovascular morbidity and mortality. Priorities to improve clinical practice include more education among clinicians about diagnosis and management, clinical decision support to aid in diagnosis, and routine use of ambulatory BP monitoring to aid in diagnosis and to monitor response to treatment.

    Full Text Available Cutaneous leishmaniasis (CL is a widespread tropical infection which has a high incidence rate in Iran. Leishmania tropica, the causative agent of anthroponotic cutaneous leishmaniasis (ACL, and Leishmania major, which causes zoonotic cutaneous leishmaniasis (ZCL, are endemic in various parts of Iran with a high incidence rate. The aim of this study was to evaluate the reappraisal of the diagnosis and epidemiology of CL in Iran, by different clinical, parasitological and molecular assays among patients suspected of CL referred to the Department of Parasitology, at the Pasteur Institute of Iran during 2006-2009. Two hundred samples from patients with ulcerative skin lesions were collected, clinical analyses were applied, data questionnaire was completed and samples were examined for CL by using both direct microscopic and culture methods. Moreover, PCR assay was applied for detection of Leishmania species in CL isolates resulting from parasitological assay. Clinical observation revealed that the majority (58% of lesions was single; double lesions were observed in 22% of patients, and only 20% of CL had multiple lesions. Out of 200 patients, Leishman body was observed in 77 samples (38.5% by direct smear and 40% by cultivation assay. Most patients (21.3% had a travel history to the Isfahan province, one of the most important endemic areas of CL located in center of Iran. PCR assay by kDNA indicated 32 and 18 out of 50 isolates respectively had similar patterns with standard L. major and L. tropica. In conclusion, clinical manifestations and an appropriate diagnostic assay with a parallel molecular characterization of CL may lead to a screening evaluation of disease, prognosis, treatment and control strategies.

    Full Text Available Congenital hypothyroidism (CH being one of the most frequent thyroid disorder among children is etiologically heterogeneous. In this study various etiological forms of primary CH (ectopic thyroid gland, athyreosis, hypoplasia, dyshormonogenesis were established by diagnostical algorithm. Complex approach with estimation of thyroid ultrasonography and scintigraphy (Tc-99m data and the level of serum thyroglobulin allowed to differentiate ectopic thyroid gland and athyreosis. In the cases of eutopic gland additional examination was necessary. The most severe clinical symptoms and laboratory changes together with the lowest level of thyroglobulin were associated with agenesis. That could optimize the diagnostic approach. High occurrence of extrathyroidal congenital malformations was revealed in patients with ectopic gland and athyreosis and in their relatives. That could indicate that genetic factors influence on the forming of thyroidal dysgenesis.

    Injuries caused by accidents or violent situations in pediatric patients are a serious social problem where prevention plays a key role. The aim of this study was to describe the epidemiological situation of pediatric injuries in Spain. A prospective study of pediatric patients receiving care in the Emergency Service of the Complejo Hospitalario de Navarra due to for reasons of accidental injury was conducted. The study covered a period of 1 year and assessed a total of 16 variables. There were a total of 8,876 patients, of whom 56.4% were males. Traumatic injuries such as fractures and craniocerebral trauma were identified as the most frequent injuries, occurring as a result of injuries mainly in the home. In females, there was a decrease in the incidence of injuries related to age. There was a greater incidence at the end of the day, during the weekend, and in the months of March to October. The epidemiological profile of pediatric patients who met with accidents in Navarra, Spain, is described. The knowledge of the main areas and factors related to injuries allows us to improve preventive measures, which would contribute to better control in this region of Spain. PMID:27414146

    Chronic interstitial lung disease (ILD) in children is a heterogeneous group of rare lung disorders characterized by an inflammatory process of the alveolar wall and the pulmonary interstitium that induces gas exchange disorders. The diagnostic approach to an ILD involves three essential steps: recognizing the ILD, appreciating the impact, and identifying the cause. The spectrum of clinical findings depends to a large extent on age. In the newborn, the beginning is often abrupt (neonatal respiratory distress), whereas there is a more gradual onset in infants (failure to thrive, tachypnea, indrawing of the respiratory muscles). In older children, the onset is insidious and the diagnosis can only be made at an advanced stage of the disease. The diagnosis is based on noninvasive methods (clinical history, respiratory function tests, chest X-ray, and high-resolution CT scan) and invasive techniques (bronchoalveolar lavage, transbronchial biopsy, video-assisted thoracoscopic biopsy, and open lung biopsy). The treatment of interstitial lung disease in children depends on the nature of the underlying pathology. The most common therapeutic approach involves the use of corticosteroids and immunosuppressive agents for their anti-inflammatory and antifibrotic effects. Children with ILD also need support therapy (oxygen therapy, nutritional support, treatment of pulmonary arterial hypertension, vaccination). Lung transplantation is discussed in patients with severe respiratory failure. PMID:27021883

  13. Children's exposure to ionizing radiations linked with diagnostic procedures in 2010 in France

    International Nuclear Information System (INIS)

    The objective of this study was to characterize the medical exposure of the French pediatric population to ionizing radiations (IR) in 2010. It only includes diagnostic procedures. Data are mainly provided by the French Health Insurance (CNAM-TS), through a representative sample of about 1% of the French population (the so-called 'EGB' sample). In 2010, more than 100,000 children from 0 to 15 years old were included in this sample. About 600 examinations per 1000 children were performed: 55% are radiological examinations and 42% dental. CT examinations are rather rare (about 2%). Nuclear medicine and interventional radiology represent less than 1% of the examinations. Children from 10 to 15 years old and babies from new born to 1 year old are the most examined. Exposure of girls and boys are rather similar. From 10 to 15 years old, dental and limbs examinations are the most frequent. Chest and pelvic examinations are the most frequent examinations performed on babies. CT pediatric examinations concern mainly the head and the neck. In 2010, a third of the French children has been exposed to at least one examination using IR. The mean and median effective doses were respectively equal to 0.65 mSv and 0.025 mSv. These values were respectively 5.7 mSv and 1.7 mSv for the children exposed to at least one CT examination (about 1% of the studied population). This study brings reference data on pediatric exposure to IR, and makes them available for public health and epidemiological purposes. This analysis should be periodically carried out to assess the evolution of the pediatric exposure. (authors)

    A survey of 308,101 primary school children in Peninsular Malaysia conducted in 1979 by the School Health Services, Ministry of Health, Malaysia, revealed that 10.7% of children were infested with Pediculus humanus capitis. The prevalence rate was higher in the economically less advanced states of Terenganu (34%), Kelantan (23%), and Perlis (21%) than in the other states (4-13%). Of 14,233 school children examined in the State of Melaka, 26% of Indians, 18.7% of Malays, 6.1% of Europeans, and 0.7% of Chinese had pediculosis. The prevalence rate, which has remained unchanged over the past 5 years, does not appear to vary with age but is higher in children with long hair and those from the lower socioeconomic groups. Boys have a lower infestation rate than do girls. The higher incidence in Indians and Malays correlates well with their lower socioeconomic status in the community, and their cultural habit of maintaining longer hair than do the Chinese. The difference become less apparent in the higher socioeconomic groups. PMID:7258487

    2015-01-01

    Full Text Available Background. In view of the alarming incidence of obesity in children, insight into the epidemiology of the prediabetic state insulin resistance (IR seems important. Therefore, the aim of this systematic review was to give an overview of all population-based studies reporting on the prevalence and incidence rates of IR in childhood. Methods. PubMed, Embase, and Cochrane library were searched in order to find all available population-based studies describing the epidemiology of IR in pediatric populations. Prevalence rates together with methods and cut-off values used to determine IR were extracted and summarized with weight and sex specific prevalence rates of IR if available. Results. Eighteen population-based studies were identified, describing prevalence rates varying between 3.1 and 44%, partly explained by different definitions for IR. Overweight and obese children had higher prevalence rates than normal weight children. In seven out of thirteen studies reporting sex specific results, girls seemed to be more affected than boys. Conclusion. Prevalence rates of IR reported in children vary widely which is partly due to the variety of definitions used. Overweight and obese children had higher prevalence and girls were more insulin resistant than boys. Consensus on the definition for IR in children is needed to allow for comparisons between different studies.

    2012-05-01

    Full Text Available With the purpose of an estimation of the contribution of virus activators in the etiological structure of acute intestinal infections in children during the rise of prevalence of acute intestinal infections from 2009 to 2011 there were studied 1050 children admitted to the hospital with diarrheal diseases. It is established, that acute intestinal infections have a viral nature in 56.67% of cases. Thus the leading role belongs to rotaviruses and adenoviruses. Infectious agents of diarrheal diseases are rotaviruses in 28.1 % of cases, adenoviruses - in 17.05 %, and astroviruses - in 11.43 %. The viral monoinfections occur more often, than mixed-infections. The rise of sporadic diseases of viral diarrhea was characterized by seasonal prevalence. For intestinal infections of viral etiology the seasonal rise in a cold season with peak of the rate of diseases of rotaviral infection in April, adenoviral infection in November, and astroviral infection in December is characteristic.

    2008-07-01

    An epidemiological study published in late 2007 described an increased risk of leukaemia in children under 5 living within 5 kilometres of German nuclear power plants. A great deal of research has been carried out on this subject since the early 1980's. The aim of this report was to provide a synthesis and critical analysis of results related to the risk of leukaemia in children and young adults aged under 25 living close to nuclear facilities. The report is structured in three sections: - a reminder of the main characteristics of childhood leukaemia and a description of the methods used to conduct epidemiological studies; - the most exhaustive review possible of epidemiological studies published in the international literature describing the frequency of leukaemia close to nuclear facilities in different countries around the world. A critical analysis is made of the published results. Some results from studies not focused on nuclear facilities are also presented. The methodological limitations associated with descriptive studies are explained and discussed; - the last section discusses the possible causes of childhood leukaemia and the main hypotheses explored to explain certain clusters of cases observed locally close to some nuclear sites. Appendices at the end of the document provide additional explanations of the concepts and methods used in epidemiology and statistics, and of the classification of malignant hemopathies. (authors)

    1994-05-01

    The epidemiology, molecular structure, cell tropism, and pathophysiology of many human disease-causing viruses have been painstakingly and elegantly characterized during the past 50 years. Vaccines and antiviral drugs of varying efficacy were developed and tested. Despite the relegation of smallpox to a freezer chest and the progress in the control of measles and hepatitis B, the viruses that cause respiratory tract infections remain significant causes of illness and death in pediatric populations worldwide. This discussion surveys the virus groups that contain nearly 200 distinct viruses that cause sporadic and epidemic respiratory infections in children. The epidemiology of infection with the influenza A and B, parainfluenza, and respiratory syncytial viruses and adenoviruses and their impact on infants and children and the groups at highest risk for morbid outcomes are discussed.

The work studies clinical and epidemiological features of the disease in 53 patients with the generalized form of meningococcal infection (GFMI who were treated in the infectious disease department of the Regional Interdistrict Children’s Clinical Hospital of Krasnoyarsk for the period 2010–2014. Results: The epidemiological situation as to MI in Krasnoyarsk for the period 2000-2013 years is characterized by the signs of interepidemic period with morbidity rises in the winter-spring period. Children from 1 year to 3 years (54,7% prevail over all MI diseased. The number of children in the first year of life decreased almost two times (from 40% to 20,7%. At the same time the proportion of children older than 4 years increased. The leading serotype among laboratory-confirmed cases of MI in Krasnoyarsk Krai is still the B group meningitis (64,7%. Conclusion: On the territory of Krasnoyarsk Krai the MI morbidity is sporadic. The generalized forms of meningococcal infection are characterized by early overt symptoms which make it possible to set a diagnosis. The clinical picture of the generalized forms of the disease almost did not change significantly.

    Full Text Available A growing number of children and adolescents drinking alcohol have become a global issue. Drinking alcohol at a young age is associated with alcohol dependence in adulthood and numerous further medical and social issues. Alcohol (ethanol is the oldest drug used since the dawn of civilization, being used as food, medicine or for religious and social purposes. It was considered a gift from gods, a belief that persisted for centuries. Although it was regarded as healing and tonic for the body, its abuse was condemned. First alcoholic beverages were those fermented naturally, wine and beer, distillation appeared during the 8-9th centuries.

    Viruses, particularly syncitial respiratory virus, are the main aetiology of community-acquired lower respiratory tract infections in infants, while bacterial agents are more frequently responsible in children older than 3 years. Antimicrobial therapy must take into account the development of reduced susceptibility of penicillin to strains of Streptoccocus pneumoniae and Haemophilus influenzae with beta-lactamase, and high frequency of Mycoplasma pneumoniae and Chlamydia pneumoniae infections. Although the mortality rate has remained low in France, the morbidity appeared to increase in recent years. PMID:10223154

    The occurrence of cancer during childhood represents one of the leading causes of death within the pediatric and adolescent age group. It is estimated that approximately 8000 children will be diagnosed annually with cancer in the United States. Epidemiologic research addressing the etiology of childhood cancer has been limited because of the difficulties in identifying a sufficiently large study population. Moreover, the use of retrospectively ascertained childhood cancer cases in epidemiologic investigations has restricted the incorporation of biological and clinical parameters. The Childrens Cancer Group has developed an active program in epidemiologic research, with over a decade of experience demonstrating the feasibility and strengths of conducting analytic epidemiologic studies within a cooperative clinical trials network. The availability of detailed clinical and biologic data on cases diagnosed within the cooperative group facilitates the transfer of state-of-the-art technology to epidemiologic research.

    Full Text Available Abstract Background Diagnostic stability and illness course of chronic non-organic psychoses are complex phenomena and only few risk factors or predictors are known that can be used reliably. This study investigates the diagnostic stability during the entire course of illness in patients with non-organic psychoses and attempts to identify non-psychopathological risk factors or predictors. Method 100 patients with functional psychosis were initially characterised using the Operational Criteria Checklist for Psychotic Illness and Affective Illness (OPCRIT, medical records and health registers. To study the stability of diagnoses (i.e. shifts per time, we used registry data to define four measures of diagnostic variation that were subsequently examined in relation to four possible measures of time (i.e. observation periods or hospitalisation events. Afterwards, we identified putative co-variables and predictors of the best measures of diagnostic stability. Results All four measures of diagnostic variation are very strongly associated with numbers-of-hospitalisations and less so with duration-of-illness, duration-of-hospitalisation and with year-of-first-admission. The four measures of diagnostic variation corrected for numbers-of-hospitalisations were therefore used to study the diagnostic stability. Conventional predictors of illness course – e.g. age-of-onset and premorbid-functioning – are not significantly associated with stability. Only somatic-comorbidity is significantly associated with two measures of stability, while family-history-of-psychiatric-illness and global-assessment-of-functioning (GAF scale score show a trend. However, the traditional variables age-of-first-admission, civil-status, first-diagnosis-being-schizophrenia and somatic-comorbidity are able to explain two-fifth of the variation in numbers-of-hospitalisations. Conclusion Diagnostic stability is closely linked with the contact between patient and the healthcare system

    TBM in children. This will enhance diagnostic confidence, allow early institution of therapy and could reduce expenditure on contrast medium, scan time and radiation exposure. With the use of threshold techniques we believe that the pre-contrast hyperdensity may be detectable by a computer program that will facilitate diagnosis, and may also be modified to detect abnormal enhancement. Basal enhancement is a sensitive sign for the diagnosis of TBM and should be sought after contrast medium administration when no hyperdensity is seen in the basal cisterns or when this finding needs to be confirmed. The CT scan feature of hyperdense exudates on pre-contrast scans should be added to the inclusion criteria for the diagnosis of TBM in children. (orig.)

    International Nuclear Information System (INIS)

    Objective: To retrospectively analyze CT appearances and diagnostic value of pelvic masses in 50 children proved by operation and pathology. Methods: 50 cases of pelvic masses were performed with axial plain CT scan. 32 cases of them underwent contrast-enhanced CT scan. These were 31 girls and 19 boys. The age ranged from 2 hours to 14 years, mean 5.8 years. 47 cases were proved by surgical pathology, 2 cases by biopsy pathology, and 1 case by voiding cystourethrography. Results: The pelvic masses were : 27 germ cell tumors, 7 rhabdomyosarcomas (RMS), 4 tumors of neural origin, 2 hydrometrocolpos, 1 pelvic lipomatosis, 1 ureterocele in bladder, 1 non-Hodgkin's lymphoma(NHL), 1 ectopic hyperplasia of prostate in pelvic, 1 appendiceal abscess, 1 prostatic abscess,1 megabladder, 1 mesenteric cyst, 1 duplication of the small intestine, 1 leiomyosarcoma. 46 of 50 cases were correctly diagnosed by CT scan before surgery (92 %), 4 cases were mistaken by CT scan (8 %). 31 cases were benign masses (62%), and 19 cases were malignant masses (38% ), 17 of 19 malignant masses were solid (89.5%). 29 of 31 benign masses were mixed density masses and cystic masses(93. 5%) . Conclusion: CT scan was the best method of choices in showing the size, density, shape, and location of pelvic masses and its relationship to pelvic organs, musculature, and bones. Pelvic CT is the most recent technique utilized in the diagnosis of patients with pelvic masses

    Full Text Available OBJECTIVE: To analyze the frequency and prevalence of congenital heart defects in a tertiary care center for children with heart diseases. METHODS: We carried out an epidemiological assessment of the first medical visit of 4,538 children in a pediatric hospital from January 1995 to December 1997. All patients with congenital heart defects had their diagnoses confirmed at least on echocardiography. The frequency and prevalence of the anomalies were computed according to the classification of sequential analysis. Age, weight, and sex were compared between the groups of healthy individuals and those with congenital heart defects after distribution according to the age group. RESULTS: Of all the children assessed, 2,017 (44.4% were diagnosed with congenital heart disease, 201 (4.4% with acquired heart disease, 52 (1.2% with arrhythmias, and 2,268 (50% were healthy children. Congenital heart diseases predominated in neonates and infants, corresponding to 71.5% of the cases. Weight and age were significantly lower in children with congenital heart defects. Ventricular septal defect was the most frequent acyanotic anomaly, and tetralogy of Fallot was the most frequent cyanotic anomaly. CONCLUSION: Children with congenital heart defects are mainly referred during the neonatal period and infancy with impairment in gaining weight. Ventricular septal defect is the most frequent heart defect.

  1. A molecular epidemiology survey of respiratory adenoviruses circulating in children residing in Southern Palestine.

    Directory of Open Access Journals (Sweden)

    Lina Qurei

    Full Text Available A molecular epidemiology survey was performed in order to establish and document the respiratory adenovirus pathogen profiles among children in Southern Palestine. Three hundred and thirty-eight hospitalized pediatric cases with adenovirus-associated respiratory tract infections were analyzed. Forty four cases out of the 338 were evaluated in more detail for the adenoviruses types present. All of the children resided in Southern Palestine, that is, in city, village and refugee camp environments within the districts of Hebron and Bethlehem. Human adenoviruses circulated throughout 2005-2010, with major outbreaks occurring in the spring months. A larger percent of the children diagnosed with adenoviral infections were male infants. DNA sequence analysis of the hexon genes from 44 samples revealed that several distinct adenovirus types circulated in the region; these were HAdV-C1, HAdV-C2, HAdV-B3 and HAdV-C5. However, not all of these types were detected within each year. This is the first study ever conducted in Palestine of the genetic epidemiology of respiratory adenovirus infections.

    Respiratory tract infections are a principal cause of illness and mortality in children worldwide and mostly caused by viruses. In this study, the epidemiology of 11 respiratory RNA viruses was investigated in a cohort of hospitalized children at a tertiary referral center in Riyadh from February 2008 to March 2009 using conventional and real-time monoplex RT-PCR assays. Among 174 nasopharyngeal aspirates, respiratory syncytial virus (RSV) was detected in 39 samples (22.41%), influenza A virus in 34 (19.54%), metapneumovirus (MPV) in 19 (10.92%), coronaviruses in 14 (8.05%), and parainfluenza viruses (PIVs) in 11 (6.32%). RSV, PIVs and coronaviruses were most prevalent in infants less than 6 months old, whereas MPV and influenza A virus were more prominent in children aged 7-24 and 25-60 months, respectively. The majority of the viruses were identified during winter with two peaks observed in March 2008 and January 2009. The presented data warrants further investigation to understand the epidemiology of respiratory viruses in Saudi Arabia on spatial and temporal basis. J. Med.

    2013-02-22

    Salmonella enterica subsp. enterica serovar Dublin (S. Dublin) receives increasing attention in cattle production. It is host-adapted to cattle, and leads to unacceptable levels of morbidity, mortality and production losses in both newly and persistently infected herds. Cattle health promoting institutions in several countries are currently constructing active surveillance programmes or voluntary certification programmes, and encourage control and eradication of S. Dublin infected cattle herds. There is a need to understand the underlying pathogenesis of the infection at both animal and herd level to design successful programmes. Furthermore, knowledge about and access to diagnostic tests for use in practice including information about test accuracy and interpretation of available diagnostic test methods are requested. The aim is to synthesise the abundant literature on elements of pathogenesis and diagnosis of immediate relevance for epidemiology and control of S. Dublin at animal and herd level. Relatively few in vivo studies on S. Dublin pathogenesis in cattle included more than a few animals and often showed varying result. It makes it difficult to draw conclusions about mechanisms that affect dissemination in cattle and that might be targets for control methods directed towards improving resistance against the bacteria, e.g. new vaccines. It is recommended to perform larger studies to elucidate dose-response relationships and age- and genetic effects of immunity. Furthermore, it is recommended to attempt to develop faster and more sensitive methods for detection of S. Dublin for diagnosis of infectious animals. PMID:22925272

    The aim of this was to study generate the first epidemiological data regarding the prevalence of hymenoptera allergy among school children in Ireland. Questionnaires, including six sting-specific questions (1), were distributed to the parents of primary school children aged 6-8 and 11-13, divided equally between rural and urban backgrounds. From 110 schools, 4112 questionnaires were returned. A total of 1544 (37.5%) children had been stung in their lifetime. Among the total, 5.8% of children stung experienced a large local reaction, 3.4% had a mild (cutaneous) systemic reaction (MSR) and 0.8% experienced a moderate\\/severe systemic reaction (SSR); these figures respectively represent 2.2%, 1.3% and 0.2% of the total study group. On logistic regression analysis, older children and rural children were at a higher risk of being stung (OR 1.7; 95% CI 1.4-2.; OR 1.6; 95% CI 1.4-1.8 respectively). Rural dwellers and asthma sufferers were more likely to experience an SSR (OR 4.3; 95% CI 1.4-13.5 and OR 2.8; 95% CI 1.8-4.3, respectively). Hymenoptera stings are more common in rural than urban dwelling Irish children. Asthma imparted a greater risk of SSR in this study population. Severe reactions are unusual overall, occurring in <1% of those stung, a lower prevalence than in Israeli teenagers but in keeping with other European reports relating to young children.

    Full Text Available Background. Acute gastroenteritis is one of the major sources of morbidity and mortality among young children in developed and developing countries. The aim of this study was to determine the prevalence of human adenovirus- (HAdV- 40 and HAdV-41 in children hospitalized with gastroenteritis in five different health centers of Iran. Methods. In a cross-sectional epidemiological study, we studied 2682 fecal specimens that were collected from children under the age of 5 years in five educational and therapeutic pediatric centers in Iran from February 2012 to February 2013. Samples were tested for HAdV-40 and HAdV-41, using a specific pair of primers in polymerase chain reaction (PCR method. Results. HAdV-40 and HAdV-41 were detected in 132 (5.18% of the patients with diarrhea. A significantly higher prevalence of HAdV-40 and HAdV-41 (58.3% was observed in children under 12 months of age, compared to other age groups. The male to female ratio was 1.7. Conclusion. The results of this study demonstrated that HAdV-40 and HAdV-41 could be considered etiological agents for acute gastroenteritis among children in Iran. The PCR as a rapid test may increase the chance for a relatively mild course of the disease followed by a complete recovery and avoiding administration of unnecessary antibiotics.

    Children with human immunodeficiency virus (HIV) have an increased risk of developing Kaposi Sarcoma (KS) and non-Hodgkin lymphoma (NHL) compared to HIV-negative children. We compiled currently published epidemiologic data on KS and NHL among children in sub-Saharan Africa (SSA). Among countries with available data, the median incidence of KS was 2.05/100,000 in the general pediatric population and 67.35/100,000 among HIV-infected children. The median incidence of NHL was 1.98/100,000 among the general pediatric population, while data on NHL incidence among HIV-infected children were lacking. Larger regional studies are needed to better address the dearth of epidemiologic information on pediatric KS and NHL in SSA. PMID:27082516

    Restorative sleep is an important factor for well-being, performance and quality of life. The basic diagnostic procedure of a sleep disorder is to take a comprehensive sleep history. Sleep disorders can and must be distinguished from the physiological changes of sleep in the elderly. Insomnia (difficulty in sleeping), daytime sleepiness (hypersomnia), sleep-related breathing disorders (SRBD) and movement disorders during sleep are also common in the elderly. They must be detected because they are treatable and can dominate the clinical picture of geriatric syndromes.

  19. Wilson's disease in children: clinical and diagnostic features

    International Nuclear Information System (INIS)

    Objective: To study the clinical and diagnostic laboratory features of Wilsons disease in children and adolescents. Design: A prospective cohort study. Place and Duration of study: The study included patients diagnosed as Wilson s disease at the Department of Pediatrics Allied Hospital, Punjab medical College, Faisalabad from May 1997 to June 2001. Patients and methods: Patients presenting with liver or suggestive neurological disease were investigated. Others were diagnosed as a result of family screening. Diagnosis of neurologic disease was made if two of the following were present: Typical neurological findings, Kayser Fleischer corneal rings and low serum ceruloplasmin (100 mu gm) free serum copper (>10 mu gm/dl). In other forms and for family screening, 24 hours. Urinary copper (> 100 mu gm), free serum copper (>10 mu gm/dl), and wherever possible liver biopsy for histopathology and cytochemical staining by rubeanic acid was also done. Results: Twenty-seven patients with a mean age of 10.2 years were diagnosed as suffering from Wilson disease. Mean age for hepatic and neurological disease was 9 years and 11.5 years respectively. Youngest patient (neurologic) was 6 years old. 48% cases presented with neurological, 41% with hepatic and 4% with skeletal manifestations while 7 % were asymptomatic. Mean duration of symptoms before diagnosis was 6.1 months. Dysarthria (84.6%), tremors (69.2%), rigidity and poor school performance and hand writing (61.5%), dysphagia (46.1%) and dystonia (38.5%), were the most common neurologic findings. Chronic liver disease was seen in 73 % while acute forms were seen in 27 % cases. Two cases presented with fulminant hepatic failure. Consanguineous marriage of the parents was found in 70 % and family history of disease was present in 65 % cases. K-F (Kayser Fleischer) rings and low serum ceruloplasmin(<20 mg/dl) was found in 85% of all patients. In non neurologic types other tests of copper metabolism were done. Elevated urinary

    Introduction: The prevalence of asthma in Jaipur district of Rajasthan was reported as 0.96% in an earlier survey. It was far below the national average of 2.38%. It was reasoned then that this could be due to under diagnosis of asthma in the Jaipur population. Material and Methods: A resurvey of the symptomatics, not diagnosed as asthma at time of the original survey was, therefore, undertaken. The resurvey data were analysed and those who now fulfilled the twin criteria for diagnosis of asthma, as used in the original survey, were diagnosed as having asthma. The original data of these newly diagnosed asthma patients were reanalyzed in search for an alternative diagnostic criterion. Results: Of the 382 symptomatics, 344 (90%) could be resurveyed and of them, 85 now fulfilled the twin diagnostic criteria for asthma. The reanalysis of the original survey data of these patients revealed that presence of shortness of breath (SOB) had the highest sensitivity, the presence of allergic symptoms in self or the family had the highest specificity and the presence of wheezing had the highest odds ratio (OR) for diagnosing asthma. Further, the OR for diagnosing asthma increased further and was highest with the presence of SOB and 2 additional symptoms. With the use of the “symptom criteria” for diagnosis of asthma i.e. the presence of SOB with 2 additional symptoms, it would have been possible to diagnose majority of the missed cases at the time of the original survey itself. Conclusions: Based on this study data it can be concluded that (a) the twin criteria for diagnosing asthma as used in earlier surveys led to under diagnosis of asthma and (b) the use of symptom criteria alone effectively checks the problem of under diagnosis of asthma. The symptom criteria are being suggested as an alternative method for use in future epidemiological surveys on asthma. PMID:26933304

    Full Text Available Background and ObjectivesMorbidity and mortality of urinary tract infection is common in spite of prescription of effective new antibiotics. Chronic pyelonphritis is one of the important reasons of end stage renal failure. Our study is carried out on 167 children admitted in Fatemi koodacan Hospital due to urinary tract infection. Major goal of this study was determination of epidemiology of urinary tract infection.Methods This study was cross sectional descriptive and sampling method was census. Various Factors such as age, gender, causative pathogen, used antibiotics and required time for getting negative urine culture test were studied. data were collected by means questionnaire.ResultsAccording to the study urinary tract infection was more common in females (74.2% of all cases while in male neonates it is more common than females. Incidence peak of urinary tract infection is seen in children between 1-6 years old. The most common pathogens responsible to urinary tract infection was E. coli and Klebsiella. The most common background disease was vesicoureteral reflux. The most common prescribed antibiotic was ceftriaxone (65%. After 2 days of taking antibiotic the majority of patients (87.7% had negative urine culture.ConclusionIn our study E. coli and Klebsiella are the most common pathogen responsible to urinary tract infection. In our study the frequency of urinary tract infection with Proteus was low (only 1.1% in comparison with other studies.

    Infectious hypodermal and hematopoietic necrosis virus (IHHNV) is one of the major viral pathogens of penaeid shrimps worldwide, which has resulted in severe mortalities of up to 90 % in cultured Penaeus (Litopenaeus) stylirostris from Hawaii and hence designated Penaeus stylirostris densovirus (PstDNV). IHHNV is distributed in shrimp culture facilities worldwide. It causes large economic loss to the shrimp farming industry. Our knowledge about the natural reservoirs of IHHNV is still scarce. Recent studies suggest that there is sufficient sequence variation among the isolates from different locations in Asia, suggesting multiple geographical strains of the virus. Four complete genomes and several partial sequences of the virus are available in the GenBank. Complete genome information would be useful for assessing the specificity of diagnostics for viruses from different geographical areas. Comparisons of complete genome sequences will help us gain insights into point mutations that can affect virulence of the virus. In addition, because of unavailability of shrimp cell lines for culturing IHHNV in vitro, quantification of virus is difficult. The recent progress in research regarding clinical signs, geographical distribution, complete genome sequence and genetic variation, transmission has made it possible to obtain information on IHHNV. A comprehensive understanding of IHHNV infection process, pathogenesis, structural proteins and replication is essential for developing prevention measures. To date, no effective prophylactic measure for IHHNV infection is available for shrimp to reduce its impact. This review provides an overview of key issues regarding IHHNV infection and disease in commercially important shrimp species. PMID:23997444

    We have examined the genetic variability of Mycoplasma bovis strains submitted to the Pennsylvania Animal Diagnostics Laboratory, University Park (PA-ADL), between December 2007 and December 2008. Of 4,868 total samples submitted for Mycoplasma testing, 302 were determined to be culture positive. Mycoplasma bovis (63.6%), Mycoplasma californicum (7.3%), Mycoplasma bovirhinis (2.7%), Mycoplasma bovigenitalium (0.7%), Mycoplasma alkalescens (4.9%), Mycoplasma putrefaciens (0.3%), and Mycoplasma dispar (1.3%) and unidentified Mycoplasma sp. (19.2%) were identified using PCR. Mycoplasma bovis represented the largest portion of the positive samples submitted. Each of the 192 M. bovis isolates was examined for variations in the BglII and MfeI restriction sites of the DNA using amplified fragment length polymorphism fingerprinting and subsequently compared with the M. bovis type strain PG45 (ATCC 25523). Similarity between strains was calculated using the Dice similarity coefficient, which ranged from approximately 0.7 to 1.0. When clustering the isolates at greater than 95% similarity, it was determined that 11 distinct clusters were present. The results are consistent with the existence of at least 2 clonally distinct groups. No clear geographical, month of isolation, or source origination relationship was identified, indicating that a currently unclassified characteristic is responsible for the strain heterogeneity. These data indicate strong heterogeneity of M. bovis isolates submitted to PA-ADL. Additionally, multiple sites throughout Pennsylvania had isolates of separate clonal lineages present concomitantly, indicating the ability of multiple overlapping outbreaks to occur at a single location. Mycoplasma bovis represents the largest portion of Mycoplasma species isolated from PA-ADL samples. We propose that amplified fragment length polymorphism may serve as a valuable tool for molecular characterization of M. bovis strains from the United States. PMID:21426978

    Objectives: To assess the epidemiological profile of asthma in school going children in Srinagar, Kashmir. Study design: Cross-sectional study. Setting: Thirty-one schools with proportionate representation from both government and private schools as well as from primary, middle, and high schools. Participants: School children aged 10–16 years with equal representation of sex and all ages. Main Outcome Measure: Prevalence of current and past asthma. Methods and Results: After administering a modified pretested questionnaire, peak expiratory flow measurement was carried. Children who had asthma-like symptoms or positive family history of asthma or physician-labeled asthma were subjected to spirometry and bronchodilator reversibility. Out of 806 children, bronchial asthma was seen in 60 (prevalence of 7.4%) which included 34 boys and 26 girls. Majority of asthmatic children (78.3% [n = 47]) had probable asthma; 6.7% (n = 4) had definite asthma; and 15% (n = 9) had physician-diagnosed asthma. Majority of children had intermittent asthma (78.3% [n = 47]). Mild persistent asthma was seen in 12.7% (n = 7) and 10% (n = 6) had moderate persistent asthma. None of the children had severe persistent asthma. The prevalence of current asthma was 3.2% (n = 26). On univariate analysis, the factors found to be statistically significant were family history of asthma (odds ratio [OR] =8.174; confidence interval [CI] =4.403–15.178), seasonal cough (OR = 4.266; CI = 2.336–7.791), allergic rhinitis (OR = 2.877; CI = 1.414–5.852), atopic dermatitis (OR = 6.597; CI = 2.72–16.004), and obesity (OR = 6.074; CI = 2.308–18.034). On multivariate analysis, family history, seasonal cough, allergic rhinitis, atopic dermatitis, and obesity were found to be significant independent risk factors. Conclusions: Srinagar qualifies as a low prevalence area for bronchial asthma in the age group of 10–16 years. Majority of children had mild intermittent asthma resulting in under diagnosis and

There is no alternative to the mass immunization of children and adolescents to achieve highly efficient vaccine-resistant sporadic incidence of these infections. However, amid the successes achieved, regular "grow-up" disease causes these infections spread vaccination for adults who are at risk. In military units there are similar conditions, they increase the risk of both infection and disease, especially among conscripts. The ways to improve vaccination calendars troops are discussed, including held for epidemical indications, the need for immunization of groups at risk of chicken pox, and in the future--and against other "childhood" diseases.

Patients and Methods: This is a retrospective review of all children who were admitted with suspected FBA between July 2001 and June 2010. Patient′s characteristics, history, clinical, radiographic, bronchoscopic findings, reason for delay presentation, and complications were noted. Results: A total of 158 children admitted to the hospital with suspected FBA were included in this study. The average age was 3.28 years. Forty-eight (30.3% children were presented late (more than 14 days after FBA and 110 (69.7% children were presented early (0-14 days. The common clinical manifestations of FBA were persistent cough (100% and choking (72%. The most frequent radiological finding observed was air trapping (40% followed by atelectasis (14%. Chest radiographs were normal in 32.2% patients. Ten children in early diagnosis group and 29 children in late diagnosis group presented with complications. The diagnosis delay was mainly attributed to physician misdiagnosis (41.6%. Rigid bronchoscopy was performed in all patients. Foreign body was found in all of the cases except six. Watermelon seeds and peanuts accounted for 80% of the aspiration. Conclusion: FBA is difficult to diagnose in children. Delay in diagnosis appears to result from a failure to give serious consideration to the diagnosis. Early diagnosis and removal of foreign bodies must be achieved to avoid complications.

    2010-01-01

    Editor’s note: Bipolar disorder diagnosis has been rising dramatically in children for the past decade. In response to this increase, writes Daniel Dickstein, M.D., of Bradley Hospital and Brown University, researchers at the National Institute of Mental Health and elsewhere are reviewing the diagnostic criteria. In coming years, Dickstein argues, recognizing and diagnosing bipolar disorder in children should be based more on biological markers, such as brain structure and the use of neural c...

    Full Text Available Abstract Background The epidemiology of intussusception, including its incidence, can vary between different countries. The aim of this study was to describe the epidemiology of childhood intussusception in Japan using data from a nationwide inpatient database. Methods We screened the database for eligible cases ≤ 18 years of age, who were coded with a discharge diagnosis of intussusception (International Classification of Diseases, 10th revision: K-561 between July to December in 2007 and 2008. We then selected cases according to Level 1 of the diagnostic certainty criteria developed by the Brighton Collaboration Intussusception Working Group. We examined the demographics, management, and outcomes of cases, and estimated the incidence of intussusception. Results We identified 2,427 cases of intussusception. There were an estimated 2,000 cases of infantile intussusception annually in Japan, an incidence of 180-190 cases per 100,000 infants. The median age at diagnosis was 17 months, and two-thirds of the patients were male. Treatment with an enema was successful in 93.0% of cases (2255/2427. The remainder required surgery. Secondary cases accounted for 3.1% (76/2427. Median length of hospital stay was 3 days. Of the 2,427 cases, we found 2 fatal cases associated with intussusception. Conclusions This is currently the largest survey of childhood intussusception in Asia using a standardized case definition. Our results provide an estimate of the baseline risk of intussusception in Japan, and it is higher than the risk observed in other countries.

  8. MRI in diagnostic evaluation of osteomyelitis in children

    International Nuclear Information System (INIS)

    Several MRI investigations for detecting or excluding acute and non-post-traumatic chronic osteomyelitis were performed in 31 children, osteomyelitis was evident in 21 patients. The sensitivity of MRI for osteomyelitis was 90%, and specificity was 100%. In children with confirmed osteomyelitis 23 follow-up investigations were carried out in order to evaluate duration of the medullary edema. In uncomplicated cases only treated by antibiotics edema regression was evident after 4 weeks and completed after 12-16 weeks. In cases in whom extended concomitant soft-tissue infection was depicted regression of edema was prolonged independent of surgical intervention. The study reveals that at onset of acute osteomyelitis in children MRI can replace technetium 99m-labeled scintigraphy and reduce plain-film investigations. The results support the usefulness of MRI in discrimination of isolated soft-tissue infection and noninfectious diseases of bone. (orig.)

  11. Modern diagnostic method of microelementosis of school age children

    International Nuclear Information System (INIS)

    Full text: Human and animal pathology stipulated by deficiency of vitally important (or 'essential') microelements or their excess, has got its combined name microelementosis [1]. In connection with high biological activity of microelements in organism in different physiologic and pathologic status the quantitative determination of several metals in biomedium of organism is of great importance in the study of microelement metabolism. However, objective and representative data on estimation of school children's provision with microelements are practically absent. The objective of the study was to investigate contents of microelements connected with deficiency of biometals participating in hemopoiesis (Cu, Zn, Co, Mn) in biomedium of the organism of school children in Zarafshan region of the Republic of Uzbekistan. We have applied the method of neutron-activation analysis for determination of microelements (Fe, Zn, Cu, Co, Mn) in hair, whole blood, blood serum, urine, saliva, food-stuff samples and in more than 20 elements of other biomedia, as per designed method in Nuclear Physics Institute, Republic of Uzbekistan [4]. The study was carried out on 245 practically healthy children aged 7-17, 131 boys and 33 girls living in four different areas of Samarkand region. According to the designed method the determination of Mn, Cu was done as follows: samples together with standards were packed in polyethylene container and underwent irradiation in vertical channel of the reactor by neutron flow 5x1013 neutron cm-2 sec-1, (for 15 seconds). The measurement of direct activity was conducted in 2 hours for determining of Cu and Mn. For determining of iron, cobalt, zinc the irradiation test measurement was done within 15 hours one month after irradiation by the corresponding radionuclides. In all measurement of element contents different standards were applied: Intralaboratory data was received by fixing a certain number of elements on ashless filter paper and comparison

  14. Complication rates of diagnostic cerebral arteriography in children

    International Nuclear Information System (INIS)

    Cerebral arteriography (CA) remains the gold standard in delineating both intra- and extracranial vascular anatomy. Most data relating to the safety of CA are drawn from studies of adult patients in whom the practicalities of the procedure, range of potential pathologies and comorbid factors are different from those in children. To evaluate the current local and neurological complication rates of paediatric CA in the setting of a tertiary level children's hospital in the UK. Data from patients who had undergone CA between January 1998 and July 2003 were reviewed. The medical, anaesthetic and nursing records, and angiography reports were reviewed for all identified patients. The following parameters were extracted and entered into a proforma: gender, age, ethnicity, diagnosis, cerebrovascular diagnosis, referral source, date of CA, number of vessels catheterized and local and neurological complications. A total of 176 CA studies were undertaken in 150 patients (median age 7.3 years, range neonate to 19 years; 83 males, 67 females) during the 5.5-year study period. The majority of referrals originated from the neurology (58%) and neurosurgery services (27.8%). No neurological complications or deaths occurred. Local complications occurred in eight children (4.5%). Five children had a groin haematoma and two had bleeding at the puncture site. A single child had a reduced pedal pulse distal to the site of catheterization, but Doppler imaging was normal. CA has a continuing role in the evaluation of cerebrovascular pathologies in children. Neurological complications are rare and local complications are not uncommon (around 5%), but are not usually serious. (orig.)

    International Nuclear Information System (INIS)

    Lesions of the brain denominated as unidentified bright objects (UBOs), which are not included in the diagnostic criteria for neurofibromatosis type 1 (NF1) established by the National Institutes of Health (NIH), have been detected by MRI. The purpose of this study was to investigate the possibility of including the presence of UBOs as a diagnostic criterion for NF1 in children. The study included 88 children between the ages of 2 and 18 years. The case group consisted of 40 children diagnosed with sporadic or familial NF1 according to the criteria established by the NIH. A control group consisted of 48 individuals referred for routine MRI of the brain for other complaints not related to NF1. UBOs were identified in 70% of the NF1 patients and in none of the control group. The sensitivity of the presence of UBOs for the diagnosis of NF1 was 70% (CI 53-83%), with a false-negative rate of 30% (CI 27-47%), a specificity of 100% (CI 86-100%) and a false-positive rate of 0% (CI 0-14%). Faced with the difficulties in diagnosing NF1 in children and the high frequency and specificity of the presence UBOs identified by MRI in our series, we recommend the inclusion of the presence UBOs as a diagnostic criterion for NF1 in children.

    Full Text Available Streptococcus pneumoniae is a common pathogenic cause of pediatric infections. This study investigated the serotype distribution, antimicrobial susceptibility, and molecular epidemiology of pneumococci before the introduction of conjugate vaccines in Shanghai, China.A total of 284 clinical pneumococcal isolates (270, 5, 4,3, and 2 of which were isolated from sputum, bronchoalveolar lavage fluid, blood, cerebral spinal fluid, and ear secretions, respectively from children less than 14 years of age who had not been vaccinated with a conjugate vaccine, were collected between January and December in 2013. All isolates were serotyped by multiplex polymerase chain reaction or quellung reactions and antimicrobial susceptibility testing was performed using the broth microdilution method. The molecular epidemiology of S.pneumoniae was analyzed by multilocus sequence typing (MLST.Among the 284 pneumococcal isolates, 19F (33.5%, 19A (14.1%, 23F (12.0%, and 6A (8.8% were the most common serotypes and the coverage rates of the 7-, 10-, and 13-valent pneumococcal conjugate vaccines (PCV7, PCV10, and PCV13 were 58.6%, 59.4% and 85.1%, respectively. Antimicrobial susceptibility showed that the prevalence rates of S.pneumoniae resistance to penicillin were 11.3% (32/284. Approximately 88.0% (250/284 of the isolates exhibited multi-drug resistance. MLST analysis revealed a high level of diversity, with 65 sequence types (STs among 267 isolates. Specifically, the four predominant STs were ST271 (24.3%, 65/267, ST320 (11.2%, 30/267, ST81 (9.7%, 26/267, and ST3173 (5.2%, 14/267, which were mainly associated with serotypes 19F, 19A, 23F, and 6A, respectively.The prevalent serotypes among clinical isolates from children were 19F, 19A, 23F, and 6A and these isolates showed high resistance rates to β-lactams and macrolides. The Taiwan19F-14 clone played a predominant role in the dissemination of pneumococcal isolates in Shanghai, China. Therefore, continued and

    International Nuclear Information System (INIS)

    Objective: To evaluate X-ray and MRI features of limbs in childhood acute leukemia. Methods: Thirteen children with acute leukemia in our pediatric hematology ward were recruited. All patients were pathologically diagnosed by bone marrow aspiration and complained of bone or joint pain in the first visit. Conventional X-ray and MRI examinations of algesic sites were performed before clinical treatment and after complete remission. MR images were obtained with SE-T1WI, SE-T2WI and T2WI-fat suppressed sequences and symmetrical bilateralism was requested while scanning. X-ray and MRI manifestations were evaluated and compared. Results: All 13 patients had received X-ray examinations. Among them, 6 had normal X-ray findings, whereas the other 7 (14 sites) showed various abnormalities including radiolucent metaphyseal bands (5 sites), periosteal reaction (3 sites), osteapenia (2 sites), mixed lesions (lysis- sclerosis, 1 site), and permeative pattern (3 sites). The number of patients for MRI examinations was 8 (11 sites). Among them, 6 (9 sites) showed bone marrow infiltration and bone marrow necrosis accompanied by normal X-ray findings, another 2 (2 sites) showed bone marrow infiltration associated with radiographic abnormalities of periosteal reaction and radiolucent metaphyseal bands. Four cases were followed up within 1 week when reached complete remission by chemotherapy. MR images features included reduced sizes of bone marrow infiltration lesions associated with increased signal intensity on T1WI, and disappearance of double-line sign on bone marrow necrosis accompanied by signal homogenization. However, the radiograph before and after treatment in the same cases did not differ significantly. Conclusions: MRI was earlier and more comprehensive in showing limbs bone marrow abnormality than radiogram in acute leukemia children with chief complaint of osteoarticular pains. MRI might be one of indicators in following up therapeutic effect for AL children with

    Directory of Open Access Journals (Sweden)

    Lisa M D Archibald

    Full Text Available Dyscalculia, dyslexia, and specific language impairment (SLI are relatively specific developmental learning disabilities in math, reading, and oral language, respectively, that occur in the context of average intellectual capacity and adequate environmental opportunities. Past research has been dominated by studies focused on single impairments despite the widespread recognition that overlapping and comorbid deficits are common. The present study took an epidemiological approach to study the learning profiles of a large school age sample in language, reading, and math. Both general learning profiles reflecting good or poor performance across measures and specific learning profiles involving either weak language, weak reading, weak math, or weak math and reading were observed. These latter four profiles characterized 70% of children with some evidence of a learning disability. Low scores in phonological short-term memory characterized clusters with a language-based weakness whereas low or variable phonological awareness was associated with the reading (but not language-based weaknesses. The low math only group did not show these phonological deficits. These findings may suggest different etiologies for language-based deficits in language, reading, and math, reading-related impairments in reading and math, and isolated math disabilities.

    Full Text Available BACKGROUND: Accurate data on childhood pneumonia aetiology are essential especially from regions where mortality is high, in order to inform case-management guidelines and the potential of prevention strategies such as bacterial conjugate vaccines. Yield from blood culture is low, but lung aspirate culture provides a higher diagnostic yield. We aimed to determine if diagnostic yield could be increased further by polymerase chain reaction (PCR detection of bacteria (Streptococcus pneumoniae and Haemophilus influenzae b and viruses in lung aspirate fluid. METHODS: A total of 95 children with radiological focal, lobar or segmental consolidation had lung aspirate performed and sent for bacterial culture and for PCR for detection of bacteria, viruses and Pneumocystis jirovecii. In children with a pneumococcal aetiology, pneumococcal bacterial loads were calculated in blood and lung aspirate fluid. RESULTS: Blood culture identified a bacterial pathogen in only 8 patients (8%. With the addition of PCR on lung aspirate samples, causative pathogens (bacterial, viral, pneumocystis were identified singly or as co-infections in 59 children (62%. The commonest bacterial organism was S.pneumoniae (41%, followed by H. influenzae b (6%, and the commonest virus identified was adenovirus (16%, followed by human bocavirus (HBoV (4%, either as single or co-infection. CONCLUSIONS: In a select group of African children, lung aspirate PCR significantly improves diagnostic yield. Our study confirms a major role of S.pneumoniae and viruses in the aetiology of childhood pneumonia in Africa.

    The Autism Diagnostic Observation Schedule-Second Edition (ADOS-2) was administered to eight children who are deaf and who are native American Sign Language (ASL) users with previous autism spectrum disorder (ASD) diagnosis. Classification on two different module selection criteria was compared based on: (1) standardized administration rules (signs not counted as equivalent to words) and (2) commonly utilized clinical administration (sign language complexity treated equivalently to spoken language complexity). Differential module selection resulted in discrepant classification in five of the eight cases (63%) and suggests that ADOS-2 via standardized test administration may result in a failure to identify autism among children who are deaf with primary communication in ASL. Two of the eight children (25%) did not exceed the cutoff for an ASD classification on either module administered despite previous ASD diagnosis. Overall results suggest that caution should be used when utilizing the ADOS-2 with children who are deaf who primarily communicate using ASL. PMID:25321853

We investigated 1306 stool samples collected over two years (2008-2009 from hospitalized children under 5 years of age for the presence of rotavirus strains and its genotypic diversity in Lahore. The prevalence rate during 2008 and 2009 was found to be 34% (n = 447 out of 1306. No significant difference was found between different age groups positive for rotavirus (p>0.05. A subset of EIA positive samples was further screened for rotavirus RNA through RT-PCR and 44 (49.43% samples, out of total 89 EIA positive samples, were found positive. G and P type prevalence was found as follows: G1P [4] = 3(6.81%; G1P [6] = 9(20.45%; G1P [8] = 1(2.27%; G2P [4] = 21(47.72%; G2P [8] = 1(2.27%; G9P [4] = 1(2.27%; G9P [6] = 1(2.27% and G9P [8] = 7(15.90%. Phylogenetic analysis revealed that the VP7 and VP4 sequences clustered closely with the previously detected strains in the country as well as Belgian rotaviruses. Antigenic characterization was performed by analyzing major epitopes in the immunodominant VP7 and VP4 gene segments. Although the neutralization conferring motifs were found variable between the Pakistani strains and the two recommended vaccines strains (Rotarix™ and RotaTeq™, we validate the use of rotavirus vaccine in Pakistan based on the proven and recognized vaccine efficacy across the globe. Our findings constitute the first report on rotavirus' genotype diversity, their phylogenetic relatedness and epidemiology during the pre-vaccination era in Lahore, Pakistan and support the immediate introduction of rotavirus vaccine in the routine immunization program of the country.

    The aim of this study was to determine the feasibility, accuracy and diagnostic potential of combined static-excretory MR Urography in children with sonographically detected hydronephrosis. We prospectively evaluated 28 children (11 girls and 17 boys), mean age 8.3 years (range 2 months-16 years). Static-excretory MR Urography was performed in all cases. The results of MR Urography were compared with the results of other imaging modalities, cystoscopy and surgery. In 28 children, 61 renal units were evaluated by MR Urography (the renal unit is the kidney and its draining ureter). The final diagnoses included: normal renal units (n = 23); uretropelvic junction obstruction (n = 14); megaureter (n = 8); midureteric stricture (n = 1), complicated duplicated systems (n = 5), post ESWL non-obstructive dilation (n = 2), extrarenal pelvis (n = 4), dysplastic kidney (n = 4). Complex pathology and more than one disease entity in were found in 7 children. The MRI diagnosis correlated with the final diagnosis in 57 units, with diagnostic accuracy 93.4%. In conclusions static and excretory MRU give both morphological and functional information in a single examination without exposure to ionizing radiation and iodinated contrast agent. It is a valuable imaging technique for children with upper urinary tract dilatation; especially in cases of complex congenital pathologies and severely hydronephrotic kidney. PMID:25750748

    Full Text Available OBJECTIVE: To study the epidemiology of exogenous intoxications in children and adolescents of Barra Garças, Mato Grosso, from January 2008 to September 2013.METHOD: This was a cross-sectional, retrospective, and descriptive epidemiological study. Data were collected from the Disease Notification System (Sistema de Informação de Agravos de Notificação [SINAN] of the municipality, processed using Microsoft Excel, and evaluated through BIOESTAT statistical software. The variables included were: sex; age; toxic agent; time and place of service; route of administration; circumstance; and classification of intoxication. The age range was established according to the Brazilian Institute of Geography and Statistics, comprising children aged from 0 to 9 years old and adolescents aged from 10 to 19 years old.RESULTS: A total of 125 cases of accidental exogenous poisoning was registered, including 77 children and 48 adolescents. Food and beverages (38.4% and drugs (24.0% were the most common groups of toxic agents responsible for the poisoning. The largest age group affected by intoxication was composed of children aged from 0 to 4 years old (43.2% and adolescents aged from 10 to 14 years old (19.7%. Regarding the circumstances, intoxication occurred due to suicide attempts (16.8% and accidental events (23.2% in adolescents and children, respectively. The study revealed a higher frequency of poisoning in girls.CONCLUSION: Exogenous intoxications occurred predominantly in children up to 4 years old, through the accidental consumption of food or drinks. Thus, the adoption of educational prevention programs for children's family members and caregivers is necessary.

    The aim of this systematic review is to determine the diagnostic accuracy of clinical feeding evaluation (CFE) compared to instrumental assessments in detecting oropharyngeal aspiration (OPA) in children. This is important to support clinical decision-making and to provide safe, cost-effective, higher quality care. All published and unpublished studies in all languages assessing the diagnostic accuracy of CFE compared to videofluoroscopic swallowing study (VFSS) and/or fibre-optic endoscopic examination of swallowing (FEES) in detecting OPA in paediatric populations were sought. Databases were searched from inception to April 2015. Grey literature, citations, and references were also searched. Two independent reviewers extracted and analysed data. Accuracy estimates were calculated. Research reports were translated into English as required. Six studies examining the diagnostic accuracy of CFE using VFSS and/or FEES were eligible for inclusion. Sample sizes, populations studied, and CFE characteristics varied widely. The overall methodological quality of the studies, assessed with QUADAS-2, was considered 'low'. Results suggested that CFEs trialling liquid consistencies might provide better accuracy estimates than CFEs trialling solids exclusively. This systematic review highlights the critical lack of evidence on the accuracy of CFE in detecting OPA in children. Larger well-designed primary diagnostic test accuracy studies in this area are needed to inform dysphagia assessment in paediatrics. PMID:26862075

  1. CT for suspected appendicitis in children: an analysis of diagnostic errors

    International Nuclear Information System (INIS)

    Mistakes have been made by the use of CT in diagnosing children with suspected appendicitis. Although others have reported the frequency of diagnostic errors, we were unable to find any studies that addressed the specific situations in which diagnostic errors occurred in children with suspected appendicitis. To investigate the frequency and type of diagnostic errors resulting from CT of children with suspected appendicitis when compared to surgical and pathological diagnosis. We reviewed imaging, clinical and pathological data on 1,207 consecutive pediatric patients who underwent CT examination for suspected appendicitis. Imaging findings were categorized as false-positive, false-negative, or indeterminate. Errors were classified as interpretative, technical or unavoidable. Concordance between surgical and pathological findings was also evaluated. The imaging findings of 34 patients (2.8%) were discrepant with the pathological examination or clinical follow-up. The errors in 23 cases were classified as interpretive (68%) and 11 as unavoidable (32%), and no errors were classified as technical. There were 23 false-positive errors (68%), 6 false-negative errors (18%), and 5 indeterminate imaging studies (15%). Isolated CT findings of an enlarged (greater than 6 mm) appendix, fat stranding, thickened bowel or non-visualization of the distal appendix were the most common false-positive CT findings. Of these 34 patients, 22 underwent appendectomy, with 10 (45%) having discordant surgical and pathological findings. (orig.)

    International Nuclear Information System (INIS)

    To compare magnetic resonance imaging (MRI) and ultrasound in children with suspected appendicitis. In a single-centre diagnostic accuracy study, children with suspected appendicitis were prospectively identified at the emergency department. All underwent abdominal ultrasound and MRI within 2 h, with the reader blinded to other imaging findings. An expert panel established the final diagnosis after 3 months. We evaluated the diagnostic accuracy of three imaging strategies: ultrasound only, conditional MRI after negative or inconclusive ultrasound, and MRI only. Significance between sensitivity and specificity was calculated using McNemar's test statistic. Between April and December 2009 we included 104 consecutive children (47 male, mean age 12). According to the expert panel, 58 patients had appendicitis. The sensitivity of MRI only and conditional MRI was 100 % (95 % confidence interval 92-100), that of ultrasound was significantly lower (76 %; 63-85, P < 0.001). Specificity was comparable among the three investigated strategies; ultrasound only 89 % (77-95), conditional MRI 80 % (67-89), MRI only 89 % (77-95) (P values 0.13, 0.13 and 1.00). In children with suspected appendicitis, strategies with MRI (MRI only, conditional MRI) had a higher sensitivity for appendicitis compared with a strategy with ultrasound only, while specificity was comparable.

    1977-01-01

    A modelling exercise was carried out to examine the potential expenditure in a national incremental dental program for children aged six to 13. Using Relative Value Units (RVUs) as a proxy for dollars, the relative expenditures for care per child in fluoridated and fluoride-deficient areas were assessed. Dental treatment requirements were taken from existing data as far as possible. Arrangements for the delivery of care were based on existing pocicies of the American Dental Association, an services delivered were based on the recommendations of the American Academy of Pedodontics and the American Society of Dentistry for Children. Orthodontic care was limited to space maintainers and simple interceptive care. Children were assumed to receive initial care at age six, and annual maintenance care from ages seven to 13. The results showed that although restorative care would be 49.8 percent less expensive for children in fluoridated areas, total care would be only 11.9 percent less expensive. The major reason for this difference was the high proportion of annual maintenance-care costs that would be absorbed by diagnostic and preventive services using UCR fees. The necessity for much of this care is questioned under the conditions of this model, and some methods by which the dental profession might control the relatively high cost of diagnostic-preventive services are suggested.

  6. Diagnostic accuracy of modified kenneth jones scoring criteria (mkjsc) in confirmed cases of tuberculosis in children

    International Nuclear Information System (INIS)

    Background: Tuberculosis (TB) is a granulomatous disease caused by Mycobacterium tuberculosis. The gold standard for the diagnosis of tuberculosis is detection of Mycobacterium tubercle bacilli. However, clinical scoring systems are most widely used for the diagnosis of TB in children. Objective: To determine the diagnostic accuracy of modified Kenneth Jones scoring criteria (MKJSC) in conformed cases of tuberculosis. Methodology: This cross-sectional comparative study was conducted in the department of Paediatrics, King Edward Medical University / Mayo Hospital, Lahore from January to June 2007. One hundred children below 15 years of age were enrolled. They were diagnosed as suspected cases of TB on the basis of fever and cough for more than 15 days. MKJSC was applied and each child was subjected to confirmatory test for TB. Results: There was an overall male preponderance of 54%. The mean age of study population was 1.8 +- 0.7 years. Out of 100 children, 66% were diagnosed as TB cases (23 with confirmatory tests and 43 with MKJSC of 5 or more). Sensitivity, specificity, positive and negative predictive value of MKJSC was 73.91%, 44.16%, 28.33%, and 85% respectively. Diagnostic accuracy of MKJSC was 51%. Conclusion: Present study does not support the hypothesis that MKJSC is a good alternative to confirmatory tests to diagnose tuberculosis in children. However, MKJSC is a simple tool, which can be applied to improve the case detection rate in the absence of sophisticated tests. (author)

    2015-02-01

    Full Text Available Carpal tunnel syndrome (CTS is a frequent syndrome in adults, but is very rare in children. CTS was described in children with mucopolysaccharidoses (MPS as condition due to the deformation of carpal bones, deposition of glycosaminoglycans in tendosynovial tissue and connective tissue of flexor retinaculum. Electromyography is essential method for diagnostic CTS in children because typical symptoms of CTS (paresthesia, numbness of hand and fingers, atrophy and paresis of certain muscles seen in adults are absent or not realized by children with MPS because of cognitive deficit despite the presence of nerve involvement. EMG results from 40 children with different types of MPS (age 1 year 8 months to 18 years are presented. Neurophysiologic abnormalities related to CTS were found in every child with MPS I, in 80,9 % of cases – with MPS II and in every case – with MPS VI; no EMG signs of median nerve lesions incarpal channel were detected in patients with MPS III and MPS IV. CTS was bilateral in children with MPS I, II and VI, but usuallythere was an asymmetry of changes. We revealed CTS in one patient with MPS II as early as at the age 2 years 11 months. All children with MPS II had already CTS at the age of 4 years except one patient. Children with MPS I and MPS VI were not investigate before the age 4 years old, but one child 4 years old with MPS I had severe CTS. In children with MPS atrophy of thenar eminence muscles developed rapidly as complication of CTS. Therefore we recommend repeating of EMG regularly to identify earliest signs of median nerve disturbance in carpal channel and opportune surgical decompression of the entrapped nerve. It allows preserving normal function of hand that it is very important for adequate child development and quality of life.

    Full Text Available Abstract Background WHO guidelines for the treatment of young children with suspected malaria have recently changed from presumptive treatment to anti-malarial treatment guided by a blood slide or malaria rapid diagnostic test (RDT. However, there is limited evidence of the safety of this policy in routine outpatient settings in Africa. Methods Children 3-59 months of age with a non-severe febrile illness and no obvious cause were enrolled over a period of one year in a malaria endemic area of Tanzania. Treatment was determined by the results of a clinical examination and RDT result, and blood culture and serum lactate were also collected. RDT-negative children were followed up over 14 days. Results Over the course of one year, 965 children were enrolled; 158 (16.4% were RDT-positive and treated with artemether-lumefantrine and 807 (83.4% were RDT-negative and treated with non-anti-malarial medicines. Compared with RDT-positives, RDT-negative children were on average younger with a lower axillary temperature and more likely to have a history of cough or difficulty in breathing. Six (0.6% children became RDT-positive after enrolment, all of whom were PCR-negative for Plasmodium falciparum DNA at enrolment. In addition, 12 (1.2% children were admitted to hospital, one with possible malaria, none of whom died. A bacterial pathogen was identified in 9/965 (0.9% children, eight of whom were RDT-negative and one was RDT-positive, but slide-negative. Excluding three children with Salmonella typhi, all of the children with bacteraemia were ≤12 months of age. Compared to double-read research slide results RDTs had a sensitivity of 97.8% (95%CI 96.9-98.7 and specificity of 96.3% (95%CI 96.3-98.4. Conclusions Use of RDTs to direct the use of anti-malarial drugs in young children did not result in any missed diagnoses of malaria although new infections soon after a consultation with a negative RDT result may undermine confidence in results.

    Full Text Available During the last decade, new imaging techniques and biological probesprovided further insight into the pathogenesis and natural history ofurinary tract infection (UTI in children. Especially in newborns, UTIis a common cause of fever and probably the most common causeof renal parenchymal loss. In children aged equal or less than 2years, the symptoms of UTI are vague and non-specific - fever,irritability, poor feeding, vomiting, diarrhea and ill appearance. Inneonates, clinical symptoms or laboratory tests could not be usedto predict UTI episodes or eliminate the likelihood of a UTI even ifother sites of infections are clinically suggested. For this reason, thegoal of managing UTI in children is based on identifying and modifyingfactors that may increase the risk of renal parenchymal and functionalloss as from the onset of infection. Moreover, selective antimicrobialpressure is a major concern when treating children with UTI, asrenal parenchymal loss may occur within a short period of time, ifinadequate antimicrobial agents are utilized. OBJECTIVES: Thissystematic review assessed recent diagnostic and therapeuticaspects of severe UTI in children. We also summarized wellconductedstudies and the most important publications regardingdiagnosis and treatment of urinary sepsis in the pediatric population.SEARCH STRATEGY: Trials and reviews were searched in generaland specialized databases (MEDLINE, Cochrane Library andreferences were reviewed. SELECTION CRITERIA: All publishedtrials and reviews were eligible for inclusion provided they reportedresults for the pediatric population, included clinically significantevents resulting from urinary tract infection, and included specificaspects of diagnosis and therapy. DATA COLLECTION: One reviewerextracted Information. Diagnostic and therapeutic aspects of urinarysepsis in the pediatric age group were assessed.

    P. K. Iablonskiy

    2013-01-01

    Full Text Available Present study has revealed low diagnostic value of Mantoux test with 2 TE in detection of tuberculosis in MBT-infected children, thus requiring implementation of novel methods. Detectable activity of tuberculosis infection among observed children with low tuberculin sensitivity was found in 23.8% of cases, as revealed by Diaskin test, as compared to 42.7% cases in a group with moderate sensitivity to tuberculin. As shown by radiological data it was accompanied by enlargement of intrathoracic lymphatic nodes in 14.3% and 53.0% cases, respectively. The data obtained with Diaskin probe were confirmed by a reference QuantiFERON testing in 95% cases. Parameters of diagnostic value for Diaskin test are two-fold higher than for Mantoux test with 2 TE. Positivity for Diaskin test reflects activity of tuberculosis infection which is accompanied by clear clinical signs in 67.3% cases, and, in 80% cases, it ischaracterized by enlargement of intrathoracic lymphatic nodes as based on radiologic data, thus arranging a risk group for tuberculosis morbidity in children. Appropriate recommendations for these patients include a fullscale phthisiatric assessment and administration of well justified and adequate therapy.

    International Nuclear Information System (INIS)

    To compare the diagnostic accuracy of post-mortem magnetic resonance imaging (PMMR) specifically for non-cardiac thoracic pathology in fetuses and children, compared with conventional autopsy. Institutional ethics approval and parental consent was obtained. A total of 400 unselected fetuses and children underwent PMMR before conventional autopsy, reported blinded to the other dataset. Of 400 non-cardiac thoracic abnormalities, 113 (28 %) were found at autopsy. Overall sensitivity and specificity (95 % confidence interval) of PMMR for any thoracic pathology was poor at 39.6 % (31.0, 48.9) and 85.5 % (80.7, 89.2) respectively, with positive predictive value (PPV) 53.7 % (42.9, 64.0) and negative predictive value (NPV) 77.0 % (71.8, 81.4). Overall agreement was 71.8 % (67.1, 76.2). PMMR was most sensitive at detecting anatomical abnormalities, including pleural effusions and lung or thoracic hypoplasia, but particularly poor at detecting infection. PMMR currently has relatively poor diagnostic detection rates for the commonest intra-thoracic pathologies identified at autopsy in fetuses and children, including respiratory tract infection and diffuse alveolar haemorrhage. The reasonable NPV suggests that normal thoracic appearances at PMMR exclude the majority of important thoracic lesions at autopsy, and so could be useful in the context of minimally invasive autopsy for detecting non-cardiac thoracic abnormalities.

PMMR currently has relatively poor diagnostic detection rates for the commonest intra-thoracic pathologies identified at autopsy in fetuses and children, including respiratory tract infection and diffuse alveolar haemorrhage. The reasonable NPV suggests that normal thoracic appearances at PMMR exclude the majority of important thoracic lesions at autopsy, and so could be useful in the context of minimally invasive autopsy for detecting non-cardiac thoracic abnormalities.

    Full Text Available The aim of the present study was to identify specific markers that mirror liver fibrosis progression as an alternative to biopsy when biopsy is contraindicated, especially in children. After liver biopsies were performed, serum samples from 30 hepatitis C virus (HCV paediatric patients (8-14 years were analysed and compared with samples from 30 healthy subjects. All subjects were tested for the presence of serum anti-HCV antibodies. Direct biomarkers for liver fibrosis, including transforming growth factor-β1, tissue inhibitor of matrix metalloproteinase-1 (TIMP-1, hyaluronic acid (HA, procollagen type III amino-terminal peptide (PIIINP and osteopontin (OPN, were measured. The indirect biomarkers aspartate and alanine aminotransferases, albumin and bilirubin were also tested. The results revealed a significant increase in the serum marker levels in HCV-infected children compared with the healthy group, whereas albumin levels exhibited a significant decrease. Significantly higher levels of PIIINP, TIMP-1, OPN and HA were detected in HCV-infected children with moderate to severe fibrosis compared with children with mild fibrosis (p < 0.05. The diagnostic accuracy of these direct biomarkers, represented by sensitivity, specificity and positive predictive value, emphasises the utility of PIIINP, TIMP-1, OPN and HA as indicators of liver fibrosis among HCV-infected children.

    Full Text Available Abstract Background As childhood obesity increases in the U.S., the Metabolic Syndrome (MS can be assumed to be increasing in the pediatric population as well. To date, there is lack of information on the most prevalent risk factors of MS in children and the patterns of risk factors present in children met the criteria for MS. Methods Anthropometric and medical data of children 2–18 years old of a nationally representative data set (NHANES 1999–2002 were obtained and the diagnostic criteria of Cook et al. employed to determine MS prevalence. Three samples were examined: a Children 2–18 years old with non-missing data on at least three of the five diagnostic criteria but missing blood glucose data (n = 5,172, b a subsample of 12–18 year olds also providing fasting glucose data but who were not overweight or obese using the International Obesity Task Force (IOTF standards (n = 1,064, and c 12–18 year olds with blood glucose data who were overweight or obese (n = 641. Results Disease prevalence estimates were 2%, 0.7%, and 23% in the three populations. More than 10% of the children providing fasting blood levels had hyperglycemia. 2% of the overweight or obese 12–18 year olds with fasting blood glucose data met all five diagnostic criteria for MS. In all groups, elevated total triglycerides but low high density lipoprotein (HDL level affected a large proportion of the population. Conclusion Results indicate a reason for concern, since the prevalence of MS risk factors in children was high. Dyslipidemia (concurrent high total triglyceride levels and low HDL levels were prevalent in large portions of the population, even in the non-overweight. Thus, chronic disease prevention efforts in the pediatric population should not only encourage healthy body weight but also include dietary recommendations to consume diets moderately low in fat with emphasis on polyunsaturated and monounsaturated fats within recommended ratios of omega-6 and omega

  19. Establishment of local diagnostic reference levels in paediatric screen-film radiography at a children's hospital

    International Nuclear Information System (INIS)

    To assess the frequency of examination, image quality (IQ) and establishment of local diagnostic reference levels (LDRLs) in paediatric radiographic examinations. The X-ray device performance, film reject rate and IQ grading were assessed at Radiology Department of a referral and teaching children's hospital in Kenya. A questionnaire method was developed and used in recording the exposure factors used to indirectly calculate patient doses. The study established the first age- and technique- specific diagnostic reference levels (DRLs) for paediatric patients with respect to grid and non-grid radiographic techniques. The mean doses in most grid examinations exceeded the available international DRLs. The non-grid radiography imaging technique provided better IQ and an optimal patient dose. In this study, the preliminary age-specific paediatric DRLs, based on the mean values of the dose distribution, have been suggested for the type of examination considered. They form the preliminary LDRLs, which are lower than the few available international DRLs. (authors)

However, there are few standardized self-assessment instruments to meet this need. The Children’s Sleep Comic is an adapted version of the unpublished German questionnaire “Freiburger Kinderschlafcomic” and provides pictures for items and responses. Because the drawings were outdated and allowed only for qualitative analysis, we revised the comic, tested its applicability in a target sample, and suggest a procedure for quantitative analysis.Methods: All items were updated and pictures were newly drawn. We used a sample of 201 children aged 5–10 years to test the applicability of the Children’s Sleep Comic in young children and to run a preliminary analysis.Results: The Children’s Sleep Comic comprises 37 items covering relevant aspects of sleep disorders in children. Application took on average 30 minutes. The procedure was well accepted by the children, as reflected by the absence of any dropouts. First comparisons with established questionnaires indicated moderate correlations.Conclusion: The Children’s Sleep Comic is appropriate for screening sleep behavior and sleep problems in children. The interactive procedure can foster a good relationship between the investigator and the child, and thus establish the basis for successful intervention if necessary.Keywords: children, sleep, sleep disorders, diagnostic, assessment, self-rating

    Background Dengue virus infection causes major public health problems in tropical and subtropical areas. In many endemic areas, including the Lao PDR, inadequate access to laboratory facilities is a major obstacle to surveillance and study of dengue epidemiology. Filter paper is widely used for blood collection for subsequent laboratory testing for antibody and nucleic acid detection. For the first time, we demonstrate that dengue viral RNA can be extracted from dengue rapid diagnostic tests (RDT) and then submitted to real-time RT-PCR for serotyping. Methodology/Principal Findings We evaluated the Standard Diagnostics (SD) Bioline Dengue Duo RDT, a commonly used test in dengue endemic areas. First, using the QIAamp RNA kit, dengue RNA was purified from the sample pad of the NS1 RDT loaded with virus isolates of the four serotypes, then quantified by RT-PCR. We observed greater recovery of virus, with a mean of 27 times more RNA recovered from RDT, than from filter paper. Second, we evaluated dengue NS1 RDTs from patients at Mahosot Hospital, Vientiane, (99 patients) and from rural Salavan Provincial Hospital (362 patients). There was good agreement between dengue RT-PCR from NS1 RDT with RT-PCR performed on RNA extracted from patient sera, either using RDT loaded with blood (82.8% and 91.4%, in Vientiane and Salavan, respectively) or serum (91.9% and 93.9%). There was 100% concordance between RDT and serum RT-PCR of infecting dengue serotype. Conclusions/Significance Therefore, the collection of NS1 positive RDTs, which do not require cold storage, may be a novel approach for dengue serotyping by RT-PCR and offers promising prospects for the collection of epidemiological data from previously inaccessible tropical areas to aid surveillance and public health interventions.

  2. New insights into the molecular epidemiology and population genetics of Schistosoma mansoni in Ugandan pre-school children and mothers.

    Directory of Open Access Journals (Sweden)

    Martha Betson

    Full Text Available Significant numbers of pre-school children are infected with Schistosoma mansoni in sub-Saharan Africa and are likely to play a role in parasite transmission. However, they are currently excluded from control programmes. Molecular phylogenetic studies have provided insights into the evolutionary origins and transmission dynamics of S. mansoni, but there has been no research into schistosome molecular epidemiology in pre-school children. Here, we investigated the genetic diversity and population structure of S. mansoni in pre-school children and mothers living in lakeshore communities in Uganda and monitored for changes over time after praziquantel treatment. Parasites were sampled from children (<6 years and mothers enrolled in the longitudinal Schistosomiasis Mothers and Infants Study at baseline and at 6-, 12- and 18-month follow-up surveys. 1347 parasites from 35 mothers and 45 children were genotyped by direct sequencing of the cytochrome c oxidase (cox1 gene. The cox1 region was highly diverse with over 230 unique sequences identified. Parasite populations were genetically differentiated between lakes and non-synonymous mutations were more diverse at Lake Victoria than Lake Albert. Surprisingly, parasite populations sampled from children showed a similar genetic diversity to those sampled from mothers, pointing towards a non-linear relationship between duration of exposure and accumulation of parasite diversity. The genetic diversity six months after praziquantel treatment was similar to pre-treatment diversity. Our results confirm the substantial genetic diversity of S. mansoni in East Africa and provide significant insights into transmission dynamics within young children and mothers, important information for schistosomiasis control programmes.

    Full Text Available Abstract Background Prompt and correct diagnosis of malaria is crucial for accurate epidemiological assessment and better case management, and while the gold standard of light microscopy is often available, it requires both expertise and time. Portable fluorescent microscopy using the CyScope® offers a potentially quicker, easier and more field-applicable alternative. This article reports on the strengths, limitations of this methodology and its diagnostic performance in cross-sectional surveys on young children and women of child-bearing age. Methods 552 adults (99% women of child-bearing age and 980 children (99% ≤ 5 years of age from rural and peri-urban regions of Ugandan were examined for malaria using light microscopy (Giemsa-stain, a lateral-flow test (Paracheck-Pf® and the CyScope®. Results from the surveys were used to calculate diagnostic performance (sensitivity and specificity as well as to perform a receiver operating characteristics (ROC analyses, using light microscopy as the gold-standard. Results Fluorescent microscopy (qualitative reads showed reduced specificity (400 parasites/μL blood: sensitivity of 64.2% and specificity of 86.0%. Overall, the diagnostic performance of the CyScope was found inferior to that of Paracheck-Pf®. Discussion Fluorescent microscopy using the CyScope® is certainly a field-applicable and relatively affordable solution for malaria diagnoses especially in areas where electrical supplies may be lacking. While it is unlikely to miss higher parasitaemia, its application in cross-sectional community-based studies leads to many false positives (i.e. small fluorescent bodies of presently unknown origin mistaken as malaria parasites. Without recourse to other technologies, arbitration of these false positives is presently equivocal, which could ultimately lead to over-treatment; something that should be further explored in future investigations if the CyScope® is to be more widely implemented.

  4. Clinical diagnostic and intervention studies of children with semantic-pragmatic language disorder.

    The diagnosis of semantic-pragmatic language disorder (SPLD) has been the subject of a number of research studies over the last two decades. Classification and diagnostic debates, while illuminating, have done little to develop tools to improve services to these children. In this paper, two children whose communication difficulties are suggestive of an SPLD diagnosis but who have differing profiles are studied. Using existing models of psycholinguistics and pragmatics to guide assessment and intervention, the diversity of language and social communicative behaviours that are covered by the label SPLD are exemplified. Consideration is given to whether the term SPLD is appropriate for both children or whether Bishop's revision of the diagnosis to 'pragmatic language impairment' might be more useful. Methods of intervention and evaluation for semantic and pragmatic deficits in these two cases are described. It is argued that existing tools can enable accurate explanation and modelling of the communication of children with SPLD and that there is a role for intervention studies in helping to refine those tools, to improve therapies and to understand the nature of the condition more fully.

  5. Optimized diagnostic performance of brain magnetic resonance imaging in children with idiopathic growth hormone deficiency

    International Nuclear Information System (INIS)

    Purpose: The aim of this study was to search for correlations between anatomic changes in the pituitary gland and hormonal disturbances in children with short stature. Material and methods: Children with short stature were enrolled when criteria of pituitary growth hormone deficiency were partly or completely met. Magnetic resonance imaging was performed in 87 children and particular attention was given to the pituitary gland. Measurements were compared with pituitary dimensions accepted as normal in the literature. Contrast with GdDTPA was used to visualize the pituitary gland and associated structures (stalk, infundibulum). T1-weighted images in the sagittal and coronal planes were obtained. The results were statistically analyzed with non-parametric tests. Conclusions: 1. Magnetic resonance imaging is a very sensitive method for detecting changes in the pituitary gland and may well be recommended as a method of choice even though the percentage of changes detected with it is rather small. 2. The use of contrast agent may be abandoned to limit costs when searching for cause of growth deficit in children with idiopathic growth hormone deficiency, save for the following cases: hypoplasia or aplasia of the pituitary gland, transection of the stalk, empty sella syndrome or tumor in the central nervous system. 3. Pituitary volume and height appear to be of greatest diagnostic significance, while width (which varies little) can serve as an auxiliary parameter. (author)

  6. Fluoroscopy-guided insertion of nasojejunal tubes in children - setting local diagnostic reference levels

    International Nuclear Information System (INIS)

    Little is known about the radiation burden from fluoroscopy-guided insertions of nasojejunal tubes (NJTs) in children. There are no recommended or published standards of diagnostic reference levels (DRLs) available. To establish reference dose area product (DAP) levels for the fluoroscopy-guided insertion of nasojejunal tubes as a basis for setting DRLs for children. In addition, we wanted to assess our local practice and determine the success and complication rates associated with this procedure. Children who had NJT insertion procedures were identified retrospectively from the fluoroscopy database. The age of the child at the time of the procedure, DAP, screening time, outcome of the procedure, and any complications were recorded for each procedure. As the radiation dose depends on the size of the child, the children were assigned to three different age groups. The sample size, mean, median and third-quartile DAPs were calculated for each group. The third-quartile values were used to establish the DRLs. Of 186 procedures performed, 172 were successful on the first attempt. These were performed in a total of 43 children with 60% having multiple insertions over time. The third-quartile DAPs were as follows for each age group: 0-12 months, 2.6 cGy cm2; 1-7 years, 2.45 cGy cm2; >8 years, 14.6 cGy cm2. High DAP readings were obtained in the 0-12 months (n = 4) and >8 years (n = 2) age groups. No immediate complications were recorded. Fluoroscopy-guided insertion of NJTs is a highly successful procedure in a selected population of children and is associated with a low complication rate. The radiation dose per procedure is relatively low. (orig.)

    About 20% of children in the United States have been reported to live in rural communities, with child poverty rates higher and geographic isolation from resources greater than in urban communities. There have been surprisingly few studies of children living in rural communities, especially poor rural communities. The Family Life Project helped fill this gap by using an epidemiological design to recruit and study a representative sample of every baby born to a mother who resided in one of six poor rural counties over a 1-year period, oversampling for poverty and African American. 1,292 children were followed from birth to 36 months of age. This monograph described these children and used a cumulative risk model to examine the relation between social risk and children's executive functioning, language development, and behavioral competence at 36 months. Using both the Family Process Model of development and the Family Investment Model of development, observed parenting was examined over time in relation to child functioning at 36 months. Different aspects of observed parenting were examined as mediators/moderators of risk in predicting child outcomes. Results suggested that cumulative risk was important in predicting all three major domains of child outcomes and that positive and negative parenting and maternal language complexity were mediators of these relations. Maternal positive parenting was found to be a buffer for the most risky families in predicting behavioral competence. In a final model using both family process and investment measures, there was evidence of mediation but with little evidence of the specificity of parenting for particular outcomes. Discussion focused on the importance of cumulative risk and parenting in understanding child competence in rural poverty and the implications for possible intervention strategies that might be effective in maximizing the early development of these children.

    2015-10-01

    Interstitial cystitis/painful bladder syndrome (IC/PBS) is a chronic debilitating condition that is characterised by suprapubic pain and urinary symptoms such as urgency, nocturia and urinary frequency. The prevalence of the condition is increasing due to more inclusive diagnostic criteria. Herein, we review the evolving epidemiology of IC/PBS and investigate health seeking behaviour for the condition through Internet search activity. Study selection was performed in accordance with PRISMA. In addition, global search trends for the terms 'Interstitial Cystitis' and 'Painful Bladder Syndrome' from 2005 to 2015 were also evaluated using the 'Google Trends' search application. The mean search activity per month was recorded and mean activity at annual intervals calculated. Regional search activity by country and city was also measured. Prevalence rates for IC/PBS vary according to diagnostic criteria and range from 2% to 17.3% among the general population. Increased prevalence is associated with female gender and females with one first-degree relative affected. There has been an increase in global mean search activity for IC/PBS on an annual basis since 2005. The greatest increase in search activity was in USA, Canada, United Kingdom, Australia, Ireland and India respectively. The top five cities for search activity for IC/PBS were in the USA. As diagnostic criteria for IC/PBS continues to become more inclusive it is likely that the prevalence will continue to increase. This is particularly true for the USA and Canada as these regions have demonstrated the greatest increase in Internet search activity for IC/ PBS. PMID:26816850

    International Nuclear Information System (INIS)

    Ionizing radiation for diagnostic purposes are an indispensable tool in modern medicine. The increasing use of computed tomography (CT) in children and adolescents is of concern both from the point of view of radio-protection and public health. children are more sensitive to the carcinogenic effects of ionizing radiation than adults. Children also have a higher life expectancy to show any detrimental effect. Furthermore, because of their smaller mass, CT scans in children receiving higher doses of radiation in specific organs in adults.

    Full Text Available Purpose: To assess the presence or absence of a retinal cause of visual impairment using electroretinography (ERG in children with no obvious discernable cause on ocular examination. Design: Prospective observational case series. Materials and Methods: A prospective study was carried out involving 120 children with the mean age 4.4±3.2 years with visual dysfunction. All children underwent ERG under general anesthesia using a special handheld mini-Ganzfeld (Kurbisfeld dome. Results: Fifty-two (43.3% children were male and 68 (56.7% were female. The clinical diagnosis was as follows: Leber′s congenital amaurosis (LCA (n=47, achromatopsia (n=25, congenital stationary night blindness (CSNB (n=9 and others (unclassifiable, n=39. The visual acuity ranged from perception of light (PL to PL with projection in children with LCA. In the rest (n=73, some sort of visually guided behavior was discernable. Following ERG, a diagnostic reappraisal resulted as follows: LCA (n=49, achromatopsia (n=28, CSNB (n=4, cone-rod dystrophy (n=22, rod-cone degeneration (n=7, normal (n=8 and others (unclassifiable, n=2. Except for the two unclassifiable cases, ERG was successful in the diagnosis or exclusion of retinal dysfunction in the rest. By Pearson Chi-square test, there was a statistically significant association between the clinical and ERG diagnosis ( P < 0.001. Conclusion: LCA was the commonest cause of visual dysfunction in our series. A statistically significant correlation between clinical and electrophysiological diagnosis was seen. ERG helped in firmly establishing the presence or absence of global retinal dysfunction in the majority (118/120 of pediatric patients with visual dysfunction.

    Greenwood, B.

    1999-01-01

    Pneumonia causes about three million deaths a year in young children, nearly all of which are in developing countries. Streptococcus pneumoniae (the pneumococcus) is the most important bacterial cause of pneumonia in young children and so is likely to be responsible for a high proportion of these deaths. The pneumococcus is also responsible for a substantial proportion of the 100,000-500,000 deaths that occur from meningitis in children each year. The incidence of invasive pneumococcal diseas...

    Little attention has been paid to alcohol use by children aged 12 and younger. The present article summarizes findings on the prevalence of alcohol use from US national and statewide surveys of children in grades 6 and younger based on reports located in searches of the literature and the Internet. Four national surveys and seven statewide surveys of children's alcohol and drug use were located that present rates of lifetime sipping and tasting, lifetime experience of more than a sip, alcohol use in the past year, use in the past month, and use in the past week. Prevalence rates decrease with the level of involvement assessed. Alcohol use increases with age, doubling between grades four and six, with the largest jump in prevalence between grades five and six. At each grade level, boys are more likely to have used alcohol than girls. African-American children are nearly as likely as white and Hispanic children to have used alcohol. Over the past decade or so, the prevalence of both lifetime and current alcohol use has been declining in children. The failure to assess intensity of children's use hampers evaluation of the level of risk experienced by children. There is a need for ongoing nationwide surveillance of alcohol use in this population and for greater education of parents regarding the dangers of introducing children to alcohol use. PMID:17629790

Objective: To describe the epidemiological and clinical characteristics of severe community-acquired pneumonia in children after the introduction of the 10-valent pneumococcal conjugate vaccine (PCV10. Methods: A prospective study included children <5 years old hospitalized for pneumonia between October 2010 and September 2013 in a tertiary hospital. Newborns and children with comorbidities were excluded. Pneumonia classification followed the clinical and radiological criteria established by World Health Organization (WHO. Clinical history, nutritional status, immunizations, diagnosis, disease course, and prognosis were analyzed. Results: Among 452 children, almost 70% were <2 years, with no sex differences, and 10% had weight-for-age z score below than -2.0. Family income was up to one minimum wage in half the households, and 40% of mothers had completed high school. The suitability of both influenza and PCV10 vaccine schedules was ~50%. The first medical care happened later than 72 hours after the onset of symptoms in 42% of cases. Pneumonia was classified as severe or very severe in 83.9% of patients and for 23% as complicated. Global mortality was 1.5%. Hypoxia, diagnosed in 51.5% of children, looked like a better prognosis predictor than the WHO classification. Conclusion: New strategies for health care are necessary, such as the incorporation of peripheral saturometry as the

    In last decade suicide attempts and suicides among youngsters are increasing greatly and are one of the leading causes of mortality in this age group. Epidemiological data are pointing on more frequent trend of self-destructive behavior among youngsters in the world as well as in our country. Risk factors which influence on increasing number of suicide attempts and suicides in this age are different in etiology: interference of genetic influences, family dynamics and external environment (school, friends, social environment, peers, television, video, and internet). Croatia as a country in transition is also following trends in the world according to epidemiological data, what is for sure great challenge for all who participate in dealing with youngsters, especially psychiatric services. In the planning of treatment is very important to include family with intention to accomplish optimal therapeutic effect. Also, it is very important to warn parents on their part of responsibility in upbringing and developing of their adolescent. PMID:20698169

  1. Comparison of diagnostic accuracy of non invasive tests for helicobacter pylori infection in children

    International Nuclear Information System (INIS)

    To compare urea breath and stool antigen in children, with histological diagnosis for Helicobacter pylori (H.pylori) infection. Children between 3 and 15 years of age reporting in pediatric outpatient department with upper gastrointestinal symptoms were included. All the participating children underwent an upper gastrointestinal endoscopy and 3 tests namely: histopathological identification of H. pylori (the traditional gold standard), urea breath test and stool antigen test were carried out on each child. The sensitivity, specificity, and positive predictive values were calculated for each noninvasive test used in the study. A total of 54 patients completed the study with a mean age of 8.2 years. On histological examination, 72% (39) were positive for H. pylori infection. On gross endoscopic examination, only 9 patients had signs of gastritis as compared to 39 histological positives. The sensitivity, specificity and positive predictive value of stool antigen test were: 77%, 73% and 89% respectively whereas the same for urea breath test were: 79%, 80% and 91% respectively. Both the noninvasive tests were found to be sensitive and specific as compared with histological identification, for the diagnosis of H. pylori in our pediatric population. The accuracy of urea breath test was better than the stool antigen test but later was easier to perform and could fulfill the criteria for a rapid bedside diagnostic test. (author)

    Full Text Available Information concerning the disease burden of viral gastroenteritis has important implications for the use and monitoring the impact of public health policies. The present study, carried out in Córdoba city, Argentina, documents the epidemiology of severe viral diarrhea as well as the burden of viral gastrointestinal disease in the hospital children admission. A total of 133 stools were collected from hospitalized children (Town Childhood Hospital suffering from acute diarrhea and studied for the presence of Group A rotavirus, astrovirus and adenovirus 40/41 by enzyme-immuno assay, between November 1997 and October 1998. Enteric viruses accounted for 42.1% of the total diarrheal cases analyzed. Group A rotaviruses, astroviruses, adenoviruses 40/41 and mixed infections were found in 35.3, 4.5, 1.5, and 0.8% studied specimens respectively. We estimated that 1 in 27 children in the 0-35 month-old cohort/range would be annually hospitalized for a viral gastroenteritis illness. The major impact on viral diarrhea lies on rotaviral infection, accouting for 84.0% of the viral diarrheal cases analyzed and for approximately one third of severe diarrheas requiring hospital admission in Córdoba City, Argentina.

    Full Text Available Trichinellosis, a parasitic zoonosis caused by the ingestion of inadequately cooked pork containing Trichinella larvae, has been a serious health problem in Timis, the largest of the Romanian counties. The authors conducted a survey on trichinellosis in children from Timis County, emphasising epidemiological aspects. Medical records from 106 children who were hospitalised at the Victor Babes Infectious Diseases Hospital in Timisoara from 1990 to 2006 were investigated. Children affected by trichinellosis were predominantly in the 10- to 14-year-old age group (34.9%. Most patients (59.43% were inhabitants of urban areas and 59.43% of cases were males. Winter was the season when the number of cases peaked (76.42%. The highest prevalence of disease (18.87% was recorded in 1994. For 38.68% of the patients, eosinophilia ranged between 10% and 20%. The length of hospitalisation ranged from 8 to 14 days in 50.94% of cases. In recent years, human trichinellosis has decreased in Timis County as a result of an improvement in the implementation of hygiene measures. The highest prevalence of the disease recorded in 1994 can be explained by an economic transition period when national pig farms began to close. Winter was the season with the highest prevalence because people eat a lot of pork during the traditional holidays.

    Full Text Available Skin diseases are amongst the most frequent disease of school going-children in many developing as well as developed countries. The pattern and prevalence of these dermatoses depend on various epidemiological factors. The pattern and prevalence of these dermatoses can reflect the health, hygiene, socioeconomic status and the environmental condition prevailing in a certain community. In our country 100-150 million children are of school going age. The prevalence of paediatric dermatoses in various parts of India has ranged from 8.7% to 35% in school based surveys. So an effort has been made here to bring forth the pattern, prevalence and socio-demographic determinants of skin diseases among school going children in a town of South India. This study was conducted in students of class 1 to class x of the government schools in Amalapuram town of East Godavari district, Andhra Pradesh. Health education programme with emphasis on personal hygiene and environmental sanitation together with providing knowledge of the aetiology and spread of the disease and various treatments available would go a long way in controlling these diseases.

  6. Radiation doses originating from diagnostic procedures during the treatment and follow-up of children and adolescents with malignant lymphoma

    International Nuclear Information System (INIS)

    Children with malignant lymphoma undergo many diagnostic procedures that involve exposure to ionising radiation. In addition, many, but by no means all, undergo further exposure to ionising radiation during radiotherapy. While therapeutic radiation exposures are prescribed, the extent of radiation exposure arising from diagnostic procedures utilised in such children is largely unknown. We completed an audit of the radiation doses arising from diagnostic imaging procedures performed in a cohort of children with malignant lymphoma. The cumulative effective radiation dose associated with radiographic and radioisotopic procedures was derived for 81 children and adolescents with malignant lymphoma during their diagnosis, treatment and follow-up. Thirty-eight of the 42 patients (90%) with Hodgkin lymphoma were alive at study termination, with follow-up periods ranging from 1.9 to 11.7 years (median 5.3). Thirty-three of the 39 patients (85%) with non-Hodgkin lymphoma were alive at study termination with follow-up periods ranging from 2.4 to 12.3 years (median 7.5). The median effective dose was 518 mSv for patients with Hodgkin lymphoma and 309 mSv for those with non-Hodgkin lymphoma. The maximum effective dose was 1.7 Sv. The principal contributors to the effective dose were computed tomography (CT) and nuclear medicine imaging procedures using 67Ga. Protocols for the management of children and adolescents with malignant lymphoma should be reviewed in order to reduce the radiation detriment without loss of essential diagnostic information.

    Full Text Available Abstract Background The incidence of community-associated methicillin-resistant Staphylococcus aureus (MRSA has risen dramatically in the U.S., particularly among children. Although Streptococcus pneumoniae colonization has been inversely associated with S. aureus colonization in unvaccinated children, this and other risk factors for S. aureus carriage have not been assessed following widespread use of the heptavalent pneumococcal conjugate vaccine (PCV7. Our objectives were to (1 determine the prevalence of S. aureus and MRSA colonization in young children in the context of widespread use of PCV7; and (2 examine risk factors for S. aureus colonization in the post-PCV7 era, including the absence of vaccine-type S. pneumoniae colonization. Methods Swabs of the anterior nares (S. aureus were obtained from children enrolled in an ongoing study of nasopharyngeal pneumococcal colonization of healthy children in 8 Massachusetts communities. Children 3 months to S. aureus was identified and antibiotic susceptibility testing was performed. Epidemiologic risk factors for S. aureus colonization were collected from parent surveys and chart reviews, along with data on pneumococcal colonization. Multivariate mixed model analyses were performed to identify factors associated with S. aureus colonization. Results Among 1,968 children, the mean age (SD was 2.7 (1.8 years, 32% received an antibiotic in the past 2 months, 2% were colonized with PCV7 strains and 24% were colonized with non-PCV7 strains. The prevalence of S. aureus colonization remained stable between 2003–04 and 2006–07 (14.6% vs. 14.1%, while MRSA colonization remained low (0.2% vs. 0.9%, p = 0.09. Although absence of pneumococcal colonization was not significantly associated with S. aureus colonization, age (6–11 mo vs. ≥5 yrs, OR 0.39 [95% CI 0.24–0.64]; 1–1.99 yrs vs. ≥5 yrs, OR 0.35 [0.23–0.54]; 2–2.99 yrs vs. ≥5 yrs, OR 0.45 [0.28–0.73]; 3–3.99 yrs vs. ≥5 yrs, OR 0

    In the past 100 years, to our knowledge there have been approximately 12 events involving the intentional introduction of microbiologic agents into livestock and animal populations worldwide, of which three were World War I events in the United States. To the best of the authors' knowledge, there has been no recent intentional introduction of microbiologic agents (viruses or bacteria) into livestock and animal populations in the United States. The criminal or terrorist use of chemicals against animals and agriculture products have been more common. With the political, economic, and military new world order, however, the United States must maintain a vigilant posture. The framework for this vigilance must be an intelligence system sensitive to the needs of agriculture and a first-class animal disease diagnostic surveillance and response system. PMID:11572141

    Full Text Available Human papillomaviruses (HPVs comprise more than 180 genotypes. HPV infection is mainly diagnosed by molecular methods. The aim of our study was to review the main molecular methods used to diagnose HPV infection, underscoring their characteristics. Several methods have been developed for molecular diagnosis of Papilloma infection, such as those based on PCR technique. Another commercial non-PCR based diagnostic method is Hybrid Capture test; it is the only commercially available HPV DNA detection test approved by the FDA. Several Authors have suggested that viral load and E6/E7 transcripts could be used as surrogate markers of persistent HPV infection, being more specific predictors of progressive disease than the simple presence of HPV DNA. Validating clinical sensitivity and specificity of each technique and improving the interpretation of the results are essential; consequently, there is a clear need for well characterized international quality control panels to compare the various diagnostic methods. HPV DNA testing could be useful both as a primary screening test, alone or in combination with a Pap smear, for the early detection of cervical cancer precursors, and as triage test to select women with minor cytological abnormalities who will need further follow-up and to predict possible treatment failure in women with diagnosed high-grade intraepithelial lesions who have undergone excisional therapy. In the next future surveillance for HPV infections, based on these molecular methods, could represent an important step for the development of primary and secondary prophylactic interventions, such as new vaccines targeted to genotypes who might replace those previously prevalent.

    Fever of unknown origin (FUO) and unexplained fever during immune suppression in children are challenging medical problems. The aim of this study is to investigate the diagnostic value of fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) and FDG-PET combined with computed tomography (FDG-PET/CT) in children with FUO and in children with unexplained fever during immune suppression. All FDG-PET/(CT) scans performed in the Radboud university medical center for the evaluation of FUO or unexplained fever during immune suppression in the last 10 years were reviewed. Results were compared with the final clinical diagnosis. FDG-PET/(CT) scans were performed in 31 children with FUO. A final diagnosis was established in 16 cases (52 %). Of the total number of scans, 32 % were clinically helpful. The sensitivity and specificity of FDG-PET/CT in these patients was 80 % and 78 %, respectively. FDG-PET/(CT) scans were performed in 12 children with unexplained fever during immune suppression. A final diagnosis was established in nine patients (75 %). Of the total number of these scans, 58 % were clinically helpful. The sensitivity and specificity of FDG-PET/CT in children with unexplained fever during immune suppression was 78 % and 67 %, respectively. FDG-PET/CT appears a valuable imaging technique in the evaluation of children with FUO and in the diagnostic process of children with unexplained fever during immune suppression. Prospective studies of FDG-PET/CT as part of a structured diagnostic protocol are warranted to assess the additional diagnostic value. (orig.)

Materials and Methods: A total of 120 children in three studied groups were studied in this comparative study the IQ score, in three subsets of verbal IQ, performance IQ and full scale IQ, of children diagnosed with transient congenital hypothyroidism (TCH and permanent congenital hypothyroidism (PCH was measured using revised Wechsler pre-school and primary scale of intelligence and compared with the control group. The relation between IQ score with time of treatment initiation and screening thyroid stimulating hormone (TSH level was evaluated in all studied groups. Results: Mean of verbal IQ, performance IQ, and full scale IQ score was significantly higher in the control group than CH patients (both permanent and transient In PCH patients though it was not significant, there was a negative relationship between verbal IQ, performance IQ and full scale IQ and screening TSH and age of treatment initiation. In TCH patients, there was negative and significant relationship between verbal IQ ( r = −0.40 and full scale IQ ( r = −0.38 and age of treatment initiation ( r = −0.46. Conclusion: Mean IQ score in both PCH and TCH patients were lower than the control group, which correlates negatively with treatment initiation time. Though CH screening and early treatment has improved the prognosis of patients, but early and high dose of treatment in children with CH is recommended.

    37 children were examined for diagnostic improvement of the oral intestinal contrasting images in abdominal computed tomography with a hypodense solution of mannitol (n = 23) in comparison with a suspension of BaSO4 (n = 14). Because of the hypodense intestinal contrasting images the artifacts of the images induced by the bordering surface could be reduced, the condition of fullness of the intestine and the judgement of the intestinal wall improved. The parenchymatous organs and points of abdominal lymph nodes could be defined and judged more easily through the hypodense contrasting images. On the whole the picture quality of the computed tomography of the young child could be increased with the hypodense solution of mannitol. (orig.)

    Full Text Available Background: One of the common problems in children, especially infants, is gastroesophageal reflux (GER. Objectives:This study was performed to compare the diagnostic value of lower esophageal sonography with that of barium swallow. Patients and method: Our trial was a triple-blind, performed on 50 patients of 1 month to 15 years of age. The patients suspicious of having GER were evaluated by sonography and barium swallow. Esophageal pH monitoring was the standard test, and both the ultrasound and barium swallow were compared to it. Results: The results showed that sonography was 90% sensitive, vs. 50% for barium swallow. Both tests had the same specificity equal to 35%. Conclusion: We concluded that sonography was a better test than barium swallows, for evaluation of suspected patients with GER, and screening of the infants.

    Increasing numbers of children diagnosed and treated for autism spectrum disorders (ASDs) has impacted both neuropsychologists and educators. Though both play key evaluative and treatment roles, there is no available method or process in place enabling the translation of the neuropsychological report recommendations into a format educational teams can easily use, leading to a gap between neuropsychological recommendations and educational planning. In the following, we review the areas evaluated by a neuropsychologist when assessing a child with an ASD, discuss the domains targeted by educational teams when designing an educational plan, and then present a process that has met with some success creating a "bridge" between the diagnostic/assessment process and the subsequent academic planning. Though presented in the context of ASD, the process described can be used by neuropsychologists for various populations to facilitate partnerships with educators that result in improved care for the child.

    Rotaviruses (RV) are important causes of diarrhea in animals, especially in domestic animals. Of the 9 RV species, rotavirus A, B, and C (RVA, RVB, and RVC, respectively) had been established as important causes of diarrhea in pigs. The Minnesota Veterinary Diagnostic Laboratory receives swine stool samples from North America to determine the etiologic agents of disease. Between November 2009 and October 2011, 7,508 samples from pigs with diarrhea were submitted to determine if enteric pathogens, including RV, were present in the samples. All samples were tested for RVA, RVB, and RVC by real time RT-PCR. The majority of the samples (82%) were positive for RVA, RVB, and/or RVC. To better understand the risk factors associated with RV infections in swine diagnostic samples, three-level mixed-effects logistic regression models (3L-MLMs) were used to estimate associations among RV species, age, and geographical variability within the major swine production regions in North America. The conditional odds ratios (cORs) for RVA and RVB detection were lower for 1–3 day old pigs when compared to any other age group. However, the cOR of RVC detection in 1–3 day old pigs was significantly higher (p 55 day old age groups. Furthermore, pigs in the 21–55 day old age group had statistically higher cORs of RV co-detection compared to 1–3 day old pigs (p < 0.001). The 3L-MLMs indicated that RV status was more similar within states than among states or within each region. Our results indicated that 3L-MLMs are a powerful and adaptable tool to handle and analyze large-hierarchical datasets. In addition, our results indicated that, overall, swine RV epidemiology is complex, and RV species are associated with different age groups and vary by regions in North America. PMID:27145176

    The control of tuberculosis (TB) in cattle and farmed deer in New Zealand has been greatly influenced by the existence of a wildlife reservoir of Mycobacterium bovis infection, principally the Australian brushtail possum (Trichosurus vulpecula). The reduction in possum numbers in areas with endemic M. bovis infection through vigorous vector control operations has been a major contributor to the marked reduction in the number of infected cattle and farmed deer herds in the past two decades. Management of TB in cattle and farmed deer in New Zealand has involved a combination of vector control, regionalisation of diagnostic testing of cattle and deer herds, abattoir surveillance and movement control from vector risk areas. Accurate diagnosis of infected cattle and deer has been a crucial component in the control programme. As the control programme has evolved, test requirements have changed and new tests have been introduced or test interpretations modified. Subspecific strain typing of M. bovis isolates has proved to be a valuable component in the epidemiological investigation of herd breakdowns to identify whether the source of infection was domestic livestock or wildlife. New initiatives will include the use of improved models for analysing diagnostic test data and characterising disease outbreaks leading to faster elimination of infection from herds. The introduction of the National Animal Identification Tracing programme will allow better risk profiling of individual herds and more reliable tracing of animal movements. TB in cattle and farmed deer in New Zealand can only be controlled by eliminating the disease in both domestic livestock and the wildlife reservoir. PMID:24992203

    Full Text Available This epidemiologic survey aimed at assessing the prevalence of traumatic dental injuries in children seen at the Federal University of Rio de Janeiro, Brazil. The records of a total of 111 children (aged 0 to 6 years seen from 2004 to 2006 in the dental trauma clinic were surveyed, comprising a total of 201 traumatized primary teeth. Data pertaining to the child and to the trauma such as age, gender, etiology, teeth involved, type of traumatic injury, time elapsed between the trauma and seeking care, and the presence and kind of clinical and radiographic sequelae in the first visit were collected from the dental records. All variables studied were assessed by means of frequency analysis and the Chi-square test (p < 0.05. A higher prevalence of trauma was observed in boys (56.7% and in the age group from 0-3 years (73.8%. The most affected teeth were the central incisors (84.7% and the most common trauma etiology was a fall from the child's own height (63.0%. The supporting tissues were the most affected. Lateral luxation was the most frequent alteration observed (33.4%, followed by concussion (21.0%. Coronal discoloration (17.7% and external resorption (18.3% were, respectively, the most prevalent clinical and radiographic sequelae. Gender had no influence on the clinical (p = 0.54 and radiographic (p = 0.55 sequelae. Even though age had no influence on radiographic sequelae (p = 0.41, clinical sequelae were more prevalent in children aged 0 to 3 years (p = 0.03. In conclusion, traumatisms in primary teeth were more prevalent in boys, and in 0-3-year-old children. Luxation was the most frequent traumatic lesion, and coronal discoloration and external resorption were the most prevalent sequelae.

    2010-10-01

    The prevalence of pediatric obstructive sleep apnea syndrome (OSAS) is approximately 3% in children. Adenotonsillar hypertrophy is the most common cause of OSAS in children, and obesity, hypotonic neuromuscular diseases, and craniofacial anomalies are other major risk factors. Snoring is the most common presenting complaint in children with OSAS, but the clinical presentation varies according to age. Agitated sleep with frequent postural changes, excessive sweating, or abnormal sleep positions such as hyperextension of neck or abnormal prone position may suggest a sleep-disordered breathing. Night terror, sleepwalking, and enuresis are frequently associated, during slow-wave sleep, with sleep-disordered breathing. Excessive daytime sleepiness becomes apparent in older children, whereas hyperactivity or inattention is usually predominant in younger children. Morning headache and poor appetite may also be present. As the cortical arousal threshold is higher in children, arousals are not easily developed and their sleep architectures are usually more conserved than those of adults. Untreated OSAS in children may result in various problems such as cognitive deficits, attention deficit/hyperactivity disorder, poor academic achievement, and emotional instability. Mild pulmonary hypertension is not uncommon. Rarely, cardiovascular complications such as cor pulmonale, heart failure, and systemic hypertension may develop in untreated cases. Failure to thrive and delayed development are serious problems in younger children with OSAS. Diagnosis of pediatric OSAS should be based on snoring, relevant history of sleep disruption, findings of any narrow or collapsible portions of upper airway, and confirmed by polysomnography. Early diagnosis of pediatric OSAS is critical to prevent complications with appropriate interventions. PMID:21189956

  8. Modern radiological postoperative diagnostics of the hip joint in children and adults

    International Nuclear Information System (INIS)

    The assessment of bone healing and loosening of endoprosthesis material was long the primary indication for postoperative projection radiography and CT imaging of the hip joint following trauma and endoprosthesis implantation. With the increasing number of joint-preserving surgery, e. g. of surgical hip luxation and hip arthroscopy for the treatment of femoroacetabular impingement (FAI), high-resolution imaging of intra-articular pathologies before and after surgery has become increasingly important. In this review article, diagnostic imaging of the hip joint is presented following common trauma surgery and orthopedic surgery interventions. The imaging modalities of projection radiography, CT and MRI including direct MR-arthrography are discussed with regard to their diagnostic capability in the postoperative assessment of the hip joint. Among others topics, imaging is discussed following hip arthroplasty, following surgical hip luxation and arthroscopic interventions for the treatment of FAI, as well as following core decompression for avascular necrosis of the femoral head. Moreover, orthopedic interventions of the hip joint in children and adolescents are presented and the dedicated reporting of postoperative imaging is outlined.

  9. Diagnostic and therapeutic use of 131I-metaiodobenzylguanidine in children with neuroblastoma

    International Nuclear Information System (INIS)

    A total of 68 scintigraphies with 131I-metaiodobenzylguanidine (131I-MIBG) were performed in 35 children affected by neuriblastoma, and the results were compared with those obtained by other diagnostic procedures. In 46 studies, the results of 131I-MIBG scintigraphy were in accordance with biochemical and instrumental data (31 true positives, 15 true negative results). Whereas, in 22 instances the results of 131I-MIBG scintigraphy did not agree with those of other diagnostic procedures. In 13 studies 131I-MIBG was negative and other data positive (false negatives). In 9 studies 131I-MIBG was positive and other data negative. Further investigation, including surgical exploration in 5 cases, revealed no false positives. These individual cases are discussed. 131I-MIBG can thus play an important, albeit not exclusive, role in diagnosis, staging and follow-up of neuroblastoma. Disappointing results were on the other hand obtained in seven patients with advanced disease in whom therapeutic attempts were carried out with 131I-MIBG

    Background: In 1996, Donovan and colleagues represented a scoring system for better prediction of Hirschsprung disease (HD). Objectives: Our objective was to devise another scoring system that uses a checklist of radiologic and clinical signs to determine the probability of HD in suspicious patients. Patients and Methods: In a diagnostic accuracy study, 55 children with clinical manifestations of HD that referred to a training hospital from 1998 to 2011 were assessed. A checklist was used to evaluate the items proposed by contrast enema (CE), based on six subscales, including transitional zone, rectosigmoid index (RSI), irregular contractions in aganglionic region, cobblestone appearance, filling defect due to fecaloid materials and lack of meconium defecation during the first 48 hours after birth. The patients were classified as high score and low score. Sensitivity, specificity, positive predictive value and negative predictive value of our scoring system were calculated for identifying HD, in comparison with pathologically proved or ruled out HD. Results: Of the 55 patients, 36 (65.4%) cases had HD and 19 (34.6%) cases were without HD. In the HD group, 32 patients showed high scores and four patients had low scores. The sensitivity and specificity of our diagnostic scoring system were 88.9% (95% CI: 78.6% - 99.1%) and 84.2% (95% CI: 68.7% - 100%), respectively. Moreover, positive predictive value (PPV) and negative predictive value (NPV) were 91.4% (95% CI: 82.1% - 100%) and 80% (95% CI: 62.5% - 97.5%), respectively. Conclusions: Our new scoring system of CE is a useful diagnostic method in HD. If a patient’s score is high, that patient is highly suspicious to HD and reversely, when one’s score is low, the patient presents a reduced probability to be diagnosed with HD. PMID:25901256

  11. Noninvasive diagnostic methods for perceptual and motor disabilities in children with cerebral palsy

    2009-09-01

    Full Text Available The field of neuroorthopedics centers on chronic diseases demanding close clinical monitoring. We shall use several examples to show how the various noninvasive diagnostic instruments can be used to obtain insight into the central nervous system as well as into the musculoskeletal system and its morphology. The choice of the most appropriate method depends on the problem; that is, whether the method is to be applied for clinical use or for basic research. In this report we introduce various technical examination methods that are being used successfully in the fields of pediatrics, orthopedics, and neurology. The major examination instrument in pediatric diagnostics is sonography, which is being used in this report as a research instrument for the biomechanics of the musculoskeletal system, but which also gives insight into neurofunctional sequences. In orthopedics, pedography is used for diagnosing deformities of the feet. In neuroorthopedics for children pedography acts as a functional monitor for apraxia and thus allows, for example, a classification of the degree of neurological malfunctions in the lower extremities. The 3D bodyscan is used to minimize x-raying in patients with neurogenic scoliosis. This report introduces examples of the application of MRI and fMRI for basic research. The biometric measuring methods introduced provide precise data in the areas of diagnostics and monitoring and are highly valuable for further neuroorthopedic basic research. In future we expect the ever-evolving technical measuring methods to enable a deeper understanding of the primary neurological causes of and the implications for patients with cerebral palsy and other neuroorthopedic conditions. This may allow the development of new forms of therapy not necessarily predictable today.

    Muscoloskeletal neoplasms are comparatively rare and the accompanying clinical picture will mostly be rather inconclusive. The basic diagnostic measures taken are first of all aimed at a preliminary differentiation between benign and malignant changes. Should the results suggest the presence of a primary malignoma, further examinations will be needed. Unenhanced X-rays, radionuclides studies, CT and nmr imaging are currently regarded as indispensable for staging and therapy planning. The site of the tumour and its influence on adjacent anatomical structures is of particular importance as regards limb-saving procedures. Any such decision can only be made on the basis of axial as well as coronary nmr images that visualize all of the diseased bone and pertinent joints. Follow-up studies using nmr imaging are only reasonable, if the same sequences and scanning planes are examined throughout. (orig./MG) [Deutsch] Muskuloskelettale Neubildungen sind relativ selten, und ihre Klinik ist meist uncharakteristisch. Ziel der Basisdiagnostik ist die vorlaeufige Entscheidung zwischen gut- und boesartig. Bei Verdacht auf ein primaeres Malignom muessen weitere Untersuchungen durchgefuehrt werden. Fuer Staging und Therapieplanung sind derzeit Nativroentgenbilder, Szintigramm, CT und MRT unverzichtbar. Besonders im Hinblick auf ein extremitaetenerhaltendes Vorgehen ist die Beziehung des Tumors zu den umgebenden anatomischen Strukturen entscheidend. Dazu ist kernspintomographisch die Abbildung des befallenen Knochens in voller Laenge mit angrenzenden Gelenken sowohl axial als auch koronar zu fordern. Verlaufskontrollen sind in der MRT nur dann verwertbar, wenn Messsequenzen und Schnittebenen konstant gehalten werden. (orig./MG)

    Recently, an international consensus diagnostic criterion for cancer cachexia was proposed. The aim of the study is to assess the prevalence of cachexia in patients with advanced cancer and to assess the current status of the diagnosis and management of cancer cachexia. A total of 390 patients with advanced cancer were included. There were 140 patients with cachexia and the prevalence was 35.9%. The prevalence was highest in pancreatic cancer (88.9%), followed by gastric cancer (76.5%) and esophageal cancer (52.9%). Sixty-three patients with cancer cachexia have CT scans available for muscle mass evaluation and 98.4% were sarcopenic. Cachectic patients have a significantly lower overall quality of life and a higher symptom burden. According to oncology physicians, only 33 patients were considered to have cancer cachexia. The false negative rate amounted to 76.4%. The positive rate was related to the body mass index and Eastern Cooperative Oncology Group performance status of the patients. There were few types of pharmacological approaches for cancer cachexia and more than half of cachectic patients did not receive any anticachexia treatment. These results indicate that the prevalence of cachexia in advanced cancer patients was high. However, cancer cachexia was rarely recognized and clinical management for cancer cachexia was very inadequate. PMID:26317149

    Full Text Available Background: Bulimia nervosa (BN is a type of feeding disorder that starts in adolescence and presents a variety of symptoms, recurrent vomiting in the oral cavity that may reach down to the larynx - similarly to gastro-esophageal reflux, causing laryngeal and voice disorder alterations. Objective: These studies aimed at surveying the literature and investigate the studies that considered BN a risk factor for voice disorders and its epidemiology, complications, diagnostic criteria, and management. Materials and Methods: A review of the literature was done based on a survey of BIOMED CENTRAL and COCHRANE @ OVID databases, which are linked to the IMU ezproxy virtual library (http://ezp.imu.edu.my/menu. The keywords "bulimia nervosa", "teenage complications" and "voice changes" were used. Citations with summaries were chosen to limit the topic, for the period between 2000 and 2010, in English. Results: Of the ninety three papers we found, twenty three were used as a basis for this review. Among them, only three discuss BN as an etiology factor associated with voice changes in adult women, and we did not find any paper associating this with bulimic teenagers. Conclusion: It is necessary to observe laryngeal and vocal signs and symptoms associated with BN, especially in teenagers whose voices are going through a period of change. The contribution of this type of investigation, which should begin with a clinical history, is essential for minimizing the complications of bulimia nervosa. Thus, adolescents and adults with voice disorders should be investigated in greater detail.

    Krypton ventilation scans (VS) provide an index of peripheral lung function, and may be particularly useful in children unable to perform pulmonary function testing. This communication reports on three linked studies which investigated whether a routine VS in young children with cystic fibrosis (CF) is diagnostically or prognostically useful. Study 1: In a preliminary study in 1991, VS were compared with clinical examination and chest radiography (CXR) in 50 CF children (29 females, 21 males) aged 0.4-5.2 years (median 2.2 years). The chest was divided into six zones, and abnormalities scored from 0 (normal) to 2 (very abnormal). Clinical examination was unhelpful in predicting abnormalities on imaging. In five children (10%) with a normal CXR, VS was abnormal, and in a further eight children (16%), CXR markedly underestimated VS changes. Study 2: In order to determine the long-term prognostic significance of VS abnormalities, we followed up 27 (19 females, 8 males) of the children from study 1, who had had their first VS at presentation at median age 1.6 years (range 0.4-5.2), scoring the same six zones from 0 to 2. Follow-up was for a mean of 11.6 years (range 7.8-14.8). Spirometry at age 7 years showed a mean forced expiratory volume in 1 s (FEV{sub 1}) of 96% (range 46%-145%) and a mean forced vital capacity (FVC) of 96% (range 46%-145%). A poor VS score at presentation was correlated with percent predicted FEV{sub 1} at age 7 (r=0.4, P=0.042, 16% of variance explained). Those with a normal VS at presentation had a mean FEV{sub 1} at presentation of 99% (range 80%-129%). Whereas four patients had an abnormal VS, a normal CXR and a low FEV{sub 1} at age 7 years, no patient had a normal VS, an abnormal CXR and a low FEV{sub 1}at age 7 years. Study 3: Fifty children (29 females, 21 males) aged 0.5-6.0 years (median 3.8) were prospectively studied in 1998, to determine whether the findings in study 1 were stable over time, and to assess whether VS altered clinical

  20. Lessons we have learned from our children: cancer risks from diagnostic radiology

    International Nuclear Information System (INIS)

    The A-bomb survivors represent the best source of data for risk estimates of radiation-induced cancer. It is clear that children are ten times more sensitive than adults to the induction of cancer. The introduction of helical CT has transformed diagnostic radiology, especially in pediatric patients. The undoubted benefits carry the price tag of much higher doses, and in children, even higher effective doses. The A-bomb data have ''matured'' and we now have cancer risk estimates for a dose range which coincides with the organ doses from pediatric CT. Individuals exposed 50 years ago to doses comparable to those associated with helical CT today, show a small but statistically significant excess incidence of cancer. There are no assumptions, and no extrapolations involved. An abdominal helical CT scan in a young girl results in a risk of fatal cancer later in life that amounts to about one in a thousand. The risk to the individual is small, and readily balanced by the medical benefits. The public health problem is, however, significant when the small individual risk is multiplied by the 2.7 million of such procedures performed annually. Every effort is needed to minimize doses by an appropriate choice of peak kilovoltage (kVp) and milliampere-seconds (mAs), and at the same time to urge a more selective use of pediatric CT. (orig.)

    AIM: To determine prevalence of H pylori infection in symptomatic children in Buenos Aires, Argentina, and to investigate factors associated with H pylori positivity.METHODS: A total of 395 children with upper gastrointestinal symptoms referred to the Gastroenterology Unit of the Children Hospital "Sor Maria Ludovica"were evaluated for the presence of H pylori by the 13C-Urea Breath Test (13C-UBT). A questionnaire was applied to the recruited population.RESULTS: Prevalence of H pylori infection was 40.0% in tlis population (mean age 9.97 ± 3.1 years). The factors associated with H pylori positivity were number of siblings (P < 0.001), presence of pet cats (P = 0.03)and birds (P = 0.04) in the household, and antecedents of gastritis among family members (P = 0.01). After multivariate analysis, number of siblings [Odds ratio (OR)= 1.39; 95% CI, 1.20-1.61] and contact with pet cats (OR = 1.76; 95% CI, 1.00-3.09) remained as variables associated with H pylori infection.CONCLUSION: The prevalence of H pylori infection in children with upper gastrointestinal symptoms in Argentina was similar to that reported in developed countries. Children from families with a higher crowding index and presence of pet cats have a higher risk of being colonized with H pylori.

    The chest radiograms represent the basic radiological examinations of thorax. The basis for radiation protection especially in pediatrics is the exact determination of doses. The risk estimation of genome damages can be received in human peripheral blood lymphocytes using alkaline version of Comet Assay. The aim of this work was assessment and quantification of the level of DNA damage in peripheral blood lymphocytes of children during airways X-ray examinations of chest and to compare data to the dose of exposure. Doses were determined using thermoluminescence (TL) dosimetry and radiophotoluminescent (RPL) glass dosimetry system. Twenty children with pulmonary diseases, ages between 5 and 14 years were assessed. Dose measurements were conducted for poster-anterior (PA) projection on the forehead, thyroid gland, gonads, chest and back. We used a 150 kV Shimadzu CH-200 M X-ray unit. Peripheral blood samples were taken from children after and prior to X-ray exposure and were examined with the alkaline Comet Assay. Comet Assay is one of the standard techniques for assessing genome damage with variety applications in genotoxicity testing as well as fundamental research in DNA damage and repair. As a measure of DNA damage tail length was used, calculated from the centre of the head and presented in micrometers (μm). Mean value of group after irradiation was 14.04 ± 1.74 as opposed to mean value of group before irradiation that was 13.15 ± 1.33. Differences between mean tail lengths were statistically significant (P<0.05, ANOVA). In addition, correlation was found between doses in primary beam (measured on the back) and the ratio of tail length (DNA damage) before and after irradiation. Doses measured with TL and RPL dosimeters showed satisfactory agreement and both dosimetry methods are suitable for dosimetric measurements in X-ray diagnostics. (author)

    Malrotation is a congenital disorder of abnormal intestinal rotation and fixation that predisposes infants to potentially life-threatening midgut volvulus. Upper gastrointestinal tract (UGI) examination is sometimes equivocal and can lead to inaccurate diagnosis. To determine the diagnostic performance of UGI examinations in children who subsequently underwent a Ladd procedure for suspected malrotation or volvulus. We reviewed all children up to 21 years old who had undergone both a UGI examination and a Ladd procedure for possible malrotation across 9 years. Children were excluded if they had not undergone either a UGI examination or a Ladd procedure and if congenital abdominal wall defects were present. Of 229 patients identified, 166 (59% male, median age 67 days) were included. Excluded were 47 without a UGI series, 12 with omphalocele or gastroschisis, 1 without verifiable operative data, 1 who had not undergone a Ladd procedure, and 2 older than 21 years. Of the 166 patients, 40% were neonates and 73% were <12 months old, and 31% presented with bilious vomiting and 15% with abdominal distention. Of 163 patients with surgically verified malrotation, 156 had a positive UGI examination, a sensitivity of 96%. There were two patients with a false-positive UGI examination and seven with false-negative examination. Jejunal position was normal in six of the seven with a false-negative examination and abnormal in the two with a false-positive examination. Of 38 patients with surgically verified volvulus, 30 showed volvulus on the UGI series. Five required bowel resection and three died. Jejunal position can lead to inaccurate UGI series interpretation. Meticulous technique and periodic assessment of performance will help more accurately diagnose difficult or equivocal cases.

    Full Text Available Abstract Background Viral respiratory tract infections (RTI are relatively understudied in Southeast Asian tropical countries. In temperate countries, seasonal activity of respiratory viruses has been reported, particularly in association with temperature, while inconsistent correlation of respiratory viral activity with humidity and rain is found in tropical countries. A retrospective study was performed from 1982-2008 to investigate the viral etiology of children (≤ 5 years old admitted with RTI in a tertiary hospital in Kuala Lumpur, Malaysia. Methods A total of 10269 respiratory samples from all children ≤ 5 years old received at the hospital's diagnostic virology laboratory between 1982-2008 were included in the study. Immunofluorescence staining (for respiratory syncytial virus (RSV, influenza A and B, parainfluenza types 1-3, and adenovirus and virus isolation were performed. The yearly hospitalization rates and annual patterns of laboratory-confirmed viral RTIs were determined. Univariate ANOVA was used to analyse the demographic parameters of cases. Multiple regression and Spearman's rank correlation were used to analyse the correlation between RSV cases and meteorological parameters. Results A total of 2708 cases were laboratory-confirmed using immunofluorescence assays and viral cultures, with the most commonly detected being RSV (1913, 70.6%, parainfluenza viruses (357, 13.2%, influenza viruses (297, 11.0%, and adenovirus (141, 5.2%. Children infected with RSV were significantly younger, and children infected with influenza viruses were significantly older. The four main viruses caused disease throughout the year, with a seasonal peak observed for RSV in September-December. Monthly RSV cases were directly correlated with rain days, and inversely correlated with relative humidity and temperature. Conclusion Viral RTIs, particularly due to RSV, are commonly detected in respiratory samples from hospitalized children in Kuala Lumpur

  8. An epidemiological study of enuresis among primary school children in Isfahan, Iran

    International Nuclear Information System (INIS)

    To estimate the prevalence of enuresis in primary school children in Iran and to determine the factors associated with this disorder. A cross-sectional time-ordered study was performed at the Faculty of Medicine, Isfahan Medical University, Isfahan, Iran from September 2005 to January 2006. A total of 4500 self-administered questionnaires were distributed to parents of children aged 6-12 years attending 30 primary schools. From an overall response rate of 69.9%, enuresis was reported in 216 children (7%), comprising 6.2% for nocturnal enuresis according to ICD10 and 3.3% according to DSM IV, 0.5% for diurnal enuresis and 0.8% for combined day and night wetting. Primary nocturnal enuresis was reported in 166 children (5.3%). Seventy-one (50.7%) of the 140 children with nocturnal enuresis had ?3 wet nights per week. A positive family history in father and mother was seen in 51% and 39% of children with primary nocturnal enuresis respectively. Using logistic regression analysis, younger age (p<0.002), gender (p<0.0001) and low level of education of mother (p<0.028) were significant predictors of enuresis. Positive history of enuresis in father was a significant predictor of primary nocturnal enuresis (p<0.012). The prevalence of nocturnal enuresis in Iran is lower than those reported in western countries, however, higher percentage demonstrated severe enuresis. The prevalence of diurnal enuresis is lower than previous studies. Age, gender and the educational level of the mother are the main risk determinants of enuresis and the prevalence of primary nocturnal enuresis appears to be significantly related to positive history of enuresis in father.

    Sever, L.E.; Strassburg, M.A.

    1983-09-01

    This report considers several major epidemiologic aspects of neural tube defects (NTDs). After examining briefly the approaches and goals of epidemiology the traditional epidemiologic concepts of NTDs are reviewed and new interpretations of the epidemiology of these defects is suggested. Three major topics are addressed: (1) that much of our knowledge of the epidemiology of the NTDs comes from areas or periods of high rates of occurrence and that generalizations based on these data may not be applicable to low incidence situations; (2) that the etiology of these defects is multifactorial, involving interaction between genetic and nongenetic factors which may differ in their relative importance between populations; and (3) that anencephalus and spina bifida may be more epidemiologically and etiologically distinct than is usually appreciated. A final consideration deals with some recent contributions of epidemiology to screening and prenatal diagnosis programs.

    Full Text Available Abstract Background Bacterial meningitis remains a source of substantial morbidity and mortality in childhood. During the last decades gradual changes have been observed in the epidemiology of bacterial meningitis, related to the introduction of new polysaccharide and conjugate vaccines. The study presents an overview of the epidemiological patterns of acute bacterial meningitis in a tertiary children 's hospital during a 32-year period, using information from a disease registry. Moreover, it discusses the contribution of communicable disease registries in the study of acute infectious diseases. Methods In the early 1970s a Meningitis Registry (MR was created for patients admitted with meningitis in Aghia Sofia Children's Hospital in Athens. The MR includes demographic, clinical and laboratory data as well as treatment, complications and outcome of the patients. In 2000 a database was created and the collected data were entered, analyzed and presented in three chronological periods: A (1974–1984, B (1985–1994 and C (1995–2005. Results Of the 2,477 cases of bacterial meningitis registered in total, 1,146 cases (46.3% were classified as "probable" and 1,331 (53.7% as "confirmed" bacterial meningitis. The estimated mean annual Incidence Rate (IR was 16.9/100,000 for bacterial meningitis, 8.9/100,000 for Neisseria meningitidis, 1.3/100,000 for Streptococcus pneumoniae, 2.5/100,000 for Haemophilus influenzae type b (Hib before vaccination and 0.4/100,000 for Hib after vaccination. Neisseria meningitis constituted the leading cause of childhood bacterial meningitis for all periods and in all age groups. Hib was the second most common cause of bacterial meningitis before the introduction of Hib conjugate vaccine, in periods A and B. The incidence of bacterial meningitis due to Streptococcus pneumoniae was stable. The long-term epidemiological pattern of Neisseria meningitidis appears in cycles of approximately 10 years, confirmed by a significant

    This study evaluated the incidence, serotype distribution, and antimicrobial susceptibility of invasive pneumococcal disease (IPD) in Saudi Arabian children. This multicenter, prospective, clinical surveillance study included children under 5years of age, residents of one of the seven study health areas, who were brought to a study hospital with suspicion of IPD. Bacterial isolates from sterile site samples, collected less than 24h after hospital visit/admission, were identified, serotyped, and tested for antibiotic susceptibility. Between June 2007 and January 2009, 631 episodes of suspected IPD were recorded, and 623 were included in the analysis. One child (0.2%) had previously received one dose of a pneumococcal vaccine. Forty-seven episodes were positive for Streptococcus pneumoniae and three for Haemophilus influenzae. The incidence of confirmed IPD cases was estimated to be 2.5-21.6 per 100,000 children (Vaccination of Saudi Arabian children with expanded-coverage conjugate pneumococcal vaccines containing serotypes 1 and 5 could have a substantial impact to prevent IPD in this population.

  15. Inflammation of the Gonad in Prepubertal Healthy Children. Epidemiology, Etiology, and Management

    Full Text Available The prevalence, etiology, and proper management of acute gonadal inflammation in prepubertal children are still controversial, with some reports defining it as rare, while others have found it more prevalent. So far, there is no consensus on imaging studies or standard follow-up procedures. In the minority of the children, the inflammation is related to congenital genitourinary malformation and bacterial infection. The majority of children with gonadal inflammation are healthy and do not have any underlying malformations; in this group, the etiology is related to viral infection or torsion of the gonad appendix. Management is directed towards the etiology. Hence, when bacterial inflammation is suspected, antibiotics should be given and full evaluation of the urinary tract system should be performed. For patients with negative medical history, absence of fever, and normal urinalysis, the diagnosis of bacterial inflammation is very unlikely, and there is neither justification for antimicrobial antibiotic therapy nor for any further urinary tract imaging. Caution should be taken with nonverbal children and infants, or patients with any abnormal parameter. For these patients, we recommend initial management as for bacterial urinary tract infection, until urine cultures results are obtained. This paper provides a comprehensive review with the related medical literature.

    Full Text Available This cross-sectional study aimed to investigate the current prevalence and risk factors associated with intestinal polyparasitism (the concurrent infection with multiple intestinal parasite species among Orang Asli school children in the Lipis district of Pahang state, Malaysia.Fecal samples were collected from 498 school children (50.6% boys and 49.4% girls, and examined by using direct smear, formalin-ether sedimentation, trichrome stain, modified Ziehl Neelsen stain, Kato-Katz, and Harada Mori techniques. Demographic, socioeconomic, environmental, and personal hygiene information were collected by using a pre-tested questionnaire. Overall, 98.4% of the children were found to be infected by at least one parasite species. Of these, 71.4% had polyparasitism. The overall prevalence of Trichuris trichiura, Ascaris lumbricoides, hookworm, Giardia duodenalis, Entamoeba spp., and Cryptosporidium spp. infections were 95.6%, 47.8%, 28.3%, 28.3%, 14.1% and 5.2%, respectively. Univariate and multivariate analyses showed that using an unsafe water supply as a source for drinking water, presence of other family members infected with intestinal parasitic infections (IPI, not washing vegetables before consumption, absence of a toilet in the house, not wearing shoes when outside, not cutting nails periodically, and not washing hands before eating were significant risk factors associated with intestinal polyparasitism among these children.Intestinal polyparasitism is highly prevalent among children in the peninsular Malaysian Aboriginal communities. Hence, effective and sustainable control measures, including school-based periodic chemotherapy, providing adequate health education focused on good personal hygiene practices and proper sanitation, as well as safe drinking water supply should be implemented to reduce the prevalence and consequences of these infections in this population.

  2. Wandering spleen in children: a report of 3 cases and a brief literature review underlining the importance of diagnostic imaging

    International Nuclear Information System (INIS)

    Wandering spleen is a rare condition in children that is often caused by loss or weakening of the splenic ligaments. Its clinical presentation is variable; 64% of children with wandering spleen have splenic torsion as a complication. To provide up-to-date information on the diagnosis, clinical management and diagnostic imaging approaches for wandering spleen in infants and children and to underline the importance of color Doppler US and CT in providing important information for patient management. We report a series of three children with wandering spleen treated at our children's hospital over the last 6 years. All three underwent clinical evaluation, color Doppler US and CT and were surgically treated. We also reviewed 40 articles that included 55 patients younger than 18 years reported in the Medline database from 2002 to 2012. We correlated pathological data with imaging findings. Color Doppler US, the first imaging modality in investigating abdominal symptoms in children with suspected wandering spleen, yielded a diagnostic sensitivity of 54.9%, whereas CT achieved about 71.7%. Radiologic evaluation has a major role in confirming the diagnosis of a suspected wandering spleen and avoiding potentially life-threatening complications requiring immediate surgery. (orig.)

    Full Text Available Abstract Background Energy from liquids is one of the most important factors that could impact on the high prevalence of children and adolescents obesity around the world. There are few data on the liquid consumption in Brazil. The aim of this study is to evaluate the volume and quality of liquids consumed by Brazilian children and adolescents and to determine the proportion of their daily energy intake composed of liquids. Methods A multicenter study was conducted in five Brazilian cities; the study included 831 participants between 3 and 17 years of age. A four-day dietary record specific to fluids was completed for each individual, and the volume of and Kcal from liquid intake were evaluated. The average number of Kcal in each beverage was determined based on label information, and the daily energy intake data from liquids were compared with the recommendations of the National Health Surveillance Agency (Agência Nacional de Vigilância Sanitária– ANVISA, the Brazilian food regulation authority, according to each subject’s age. Results As the children aged, the volume of carbonated beverages that they consumed increased significantly, and their milk intake decreased significantly. For children between the ages of 3 and 10, milk and dairy products contributed the greatest daily number of Kcal from liquids. Sugar sweetened beverages which included carbonated beverages, nectars and artificial beverages, accounted for 37% and 45% of the total Kcal from liquid intake in the 3- to 6-year-old and 7- to 10- year-old groups, respectively. Among adolescents (participants 11- to 17- years old, most of the energy intake from liquids came from carbonated beverages, which accounted for an average of 207 kcal/day in this group (42% of their total energy intake from liquids. Health professionals should be attentive to the excessive consumption of sugar sweetened beverages in children and adolescents. The movement toward healthier dietary patterns at the

The present retrospective study has involved 150 cases of drug poisoning observed in the Casablanca children's hospital over a period of 7 years. Most intoxication cases are accidental (84%), (mostly in children of 1 to 5 years old 74.6%), willful (11.3%), or iatrogenic (4.7%). Happening most often at home (95%) with a high frequency between 5 and 6 p.m. (24%) and 11 a 12 p.m. (13.3%), time of strong hunger. The large majority of drugs wer psychotropic agents (56%), principally diazepins (39%). Followed by oral contraceptive (8%), antihistaminics (8%), analgesics (7%), antibiotics (4%) and others (11%). Prevention is of high importance, and must be made effective on the wildest scale. PMID:9689865

    Asthma is the most commonly reported chronic condition of childhood in developed countries, with 6.5 million children affected in the USA. A disparate burden of childhood asthma is seen among socioeconomically disadvantaged youth, often concentrated in urban areas with high poverty rates. Host factors that predispose a child to asthma include atopy, male gender, parental history of asthma, and also race, ethnicity, and genetic and epigenetic susceptibilities. Environmental factors, such as improved hygiene, ambient air pollution, and early life exposures to microbes and aeroallergens, also influence the development of asthma. With greater than 90 % of time spent indoors, home exposures (such as cockroach, rodent, and indoor air pollution) are highly relevant for urban asthma. Morbidity reduction may require focused public health initiatives for environmental intervention in high priority risk groups and the addition of immune modulatory agents in children with poorly controlled disease.

    Full Text Available Background and Objectives : Nutritional anemia is associated with impaired performance of a range of mental and physical functions in children, along with increased morbidity. Iron supplementation at a later age may not reverse the adverse effects. National Nutritional Anemia Control Program was launched in India in 1970, but it failed to make any impact. The present study was undertaken to find out prevalence of anemia and its correlates in rural Wardha in children 6-35 months of age. Materials and Methods : Seven hundred seventy-two children between 6 months and 35 months of age were studied for anemia by cluster-sampling method. The hemoglobin was estimated in the child by ′Filter paper cyanmethemoglobin method.′ Pre-designed and pre-tested questionnaire was used to collect data on socio-demographic and other variables. Data was analyzed by SPSS 12.0.1. Results : Mean hemoglobin level was 98.5 ± 12.9 gm/L. Prevalence of anemia was 80.3%. Only 1.3% children had severe anemia (hemoglobin < 70 gm/L. The univariate analysis showed that anemia is significantly associated with age of the child, education of mother and father, occupation of father, socioeconomic status, birth order and nutritional status as measured by weight for age. The final model suggested that only educational status of the mother, occupation of the father, birth order and nutritional status of the child were significantly associated with anemia. Interpretation and Conclusion : For short-term impact, appropriate nutritional interventions remain the only operational intervention as only the nutritional status (weight for age is a modifiable factor. But for long-term sustained impact, policy makers need to focus on improving maternal education and reducing family size.

    Full Text Available Abstract Background The aim of our study was to use a local (Glasgow, west of Scotland version of a Canadian injury surveillance programme (CHIRPP to investigate the relationship between the developmental stage of young (pre-school children, using age as a proxy, and the occurrence (incidence, nature, mechanism and location of injuries presenting to a Scottish hospital emergency department, in an attempt to replicate the findings of a recent study in Kingston, Canada. Methods We used the Glasgow CHIRPP data to perform two types of analyses. First, we calculated injury rates for that part of the hospital catchment area for which reasonably accurate population denominators were available. Second, we examined detailed injury patterns, in terms of the circumstances, mechanisms, location and types of injury. We compared our findings with those of the Kingston researchers. Results A total of 17,793 injury records for children aged up to 7 years were identified over the period 1997–99. For 1997–2001, 6,188 were used to calculate rates in the west of the city only. Average annual age specific rates per 1000 children were highest in both males and females aged 12–35 months. Apart from the higher rates in Glasgow, the pattern of injuries, in terms of breakdown factors, mechanism, location, context, and nature of injury, were similar in Glasgow and Kingston. Conclusion We replicated in Glasgow, UK, the findings of a Canadian study demonstrating a correlation between the pattern of childhood injuries and developmental stage. Future research should take account of the need to enhance statistical power and explore the interaction between age and potential confounding variables such as socio-economic deprivation. Our findings highlight the importance of designing injury prevention interventions that are appropriate for specific stages of development in children.

    International estimates of the incidence of non-accidental burns (NAB) in children admitted to burn centres vary from 1% to 25%. Hardly any data about Dutch figures exist. The aim of this study was to evaluate the incidence, treatment and outcome of burns due to suspected child abuse in paediatric burns. We described the process of care and outcome, including the accuracy of the SPUTOVAMO screening tool and examined child, burn and treatment characteristics related to suspicions of child abuse or neglect. A retrospective study was conducted in children aged 0-17 years with a primary admission after burn injuries to the burn centre Rotterdam in the period 2009-2013. Data on patient, injury and treatment characteristics were collected, using the Dutch Burn Repository R3. In addition, medical records were reviewed. In 498 paediatric admissions, suspected child abuse or neglect was present in 43 children (9%). 442 screening questionnaires (89%) were completed. In 52 out of 442 questionnaires (12%) the completed SPUTOVAMO had one or more positive signs. Significant independent predictors for suspected child abuse were burns in the genital area or buttocks (OR=3.29; CI: 143-7.55) and a low socio-economic status (OR=2.52; 95%CI: 1.30-4.90). The incidence of suspected child abuse indicating generation of additional support in our population is comparable to studies with a similar design in other countries. PMID:27211360

    Noroviruses are an important cause of gastroenteritis, which can be severe at the extremes of ages. Data documenting the endemic burden of norovirus among children and elderly adults are lacking. Stool specimens submitted for clinical testing were collected from elderly (≥65 years) adults and children (<18 years) with acute vomiting and/or diarrhea seeking care at several metropolitan Atlanta adult and pediatric hospitals from January 2013-June 2013. Specimens were tested for norovirus with real-time RT-PCR and sequenced if norovirus was detected. Corresponding clinical and demographic data were abstracted from retrospective chart review. Norovirus was detected in 11% (11/104) of elderly specimens and 11% (67/628) of pediatric, with GII.4 Sydney_2012 detected in 64% (7/11) of elderly norovirus-positive and 11% (8/67) of pediatric specimens, P < 0.001. In comparison to hospitalized children, hospitalized elderly with norovirus were more commonly admitted to the intensive care unit (ICU) (36% vs. 7%, P = 0.02). Norovirus in the elderly can be associated with severe illness requiring ICU admissions. The pediatric group demonstrated greater variability in genotype distribution. Ongoing surveillance of norovirus genotypes is crucial for norovirus vaccine development in understanding circulating and emerging genotypes. J. Med.

    Full Text Available Back ground: Intestinal parasitic infections are among the major public health problems in the Sub-Saharan Africa. However, surveys for intestinal parasites conducted in different areas of Ethiopia focused on school age children. Consequently, there is scarcity of data on the burden of intestinal parasites among children in Kindergartens. Material and Method: This cross-sectional study was conducted in three Kindergartens in Mekelle City, North Ethiopia from October to November 2013. A total of 400 (240 male and 160 female pre-school children were eligible to provide stool samples. Wet mount preparations and Kato Katz technique were applied to process stool samples. Results: The overall prevalence of intestinal parasitic infection was 29.3% in the study. Six protozoan and helminthic parasites were indentified and Hymenelopis nana was the predominant species (8.75% followed by Giardia lamblia (5.75, Entamoeba histolytica (5%, Enterobius vermicularis (5% and Ascaris lumbricoides (4%. Hookworms and Schistosomiasis mansoni were the least prevalent species. Conclusions: Intestinal parasitosis was high in the study area which indicates a need for provision of anti protozoan and anti helminthics, sanitation, provision of safe water supply and latrines accompanied by appropriate health education.

    Children with malignant lymphoma undergo many diagnostic procedures that involve exposure to ionising radiation. In addition, many, but by no means all, undergo further exposure to ionising radiation during radiotherapy. While therapeutic radiation exposures are prescribed, the extent of radiation exposure arising from diagnostic procedures utilised in such children is largely unknown. We completed an audit of the radiation doses arising from diagnostic imaging procedures performed in a cohort of children with malignant lymphoma. The cumulative effective radiation dose associated with radiographic and radioisotopic procedures was derived for 81 children and adolescents with malignant lymphoma during their diagnosis, treatment and follow-up. Thirty-eight of the 42 patients (90%) with Hodgkin lymphoma were alive at study termination, with follow-up periods ranging from 1.9 to 11.7 years (median 5.3). Thirty-three of the 39 patients (85%) with non-Hodgkin lymphoma were alive at study termination with follow-up periods ranging from 2.4 to 12.3 years (median 7.5). The median effective dose was 518 mSv for patients with Hodgkin lymphoma and 309 mSv for those with non-Hodgkin lymphoma. The maximum effective dose was 1.7 Sv. The principal contributors to the effective dose were computed tomography (CT) and nuclear medicine imaging procedures using {sup 67}Ga. Protocols for the management of children and adolescents with malignant lymphoma should be reviewed in order to reduce the radiation detriment without loss of essential diagnostic information.

We did this research to study epidemiology of diseases of infancy in city of Tehran. During 15 days, of 6395 deliveries in Tehran hospitals a cohort of 6267 live births entered this study. Follow up data were gathered in 1st, 3rd, 6th and 12th months of birth. In this period, 5382 occurrence of disease were reported. The most frequent were cardiopulmonary (52.3% and Gastrointestinal (26.6% diseases. Most of the events were seen in 6-12 months age group (30.5%. The lowest frequencies of infant diseases were seen in 19-35 years of maternal age (15.3%, as compared with >35 (35.4% and <19 (49.3% groups. Mortality ratio was 32/1000 live birth (198 death. The most common causes of death were cardiopulmonary (38%, infectious (21% and gastrointestinal (18% diseases. Control of infectious disease, development of educational programs for breast feeding and planning of proper age and interval of pregnancy are effective measures for reducing infant mortality and morbidity.

    For the air pollution control act of the middle of the Ruhr area (1980 until 1984) in 1979, under collaboration of four institutes, in an extended study epidemiological investigations in the form of a cadastre on men and women (age-classes 1914, 1915, 1916, totally abt. 3000) and boys and girls (age-class 1969, totally abt. 2.400) in the load area, as well as in one higher and one lower charged area of comparison, was executed. Target variables were diseases of the respiratory tracts, pulmonary function parameters and parameters of the internal pollution load. The results show that it cannot be excluded, that the air pollutions in the load areas may have an irritating influence on the organs of the respiratory system. Of special importance is the result, that in the tested persons the medium blood-lead concentration and the COHb-content varies with the immission load, and that also the phenol-output in the urine points out that corresponding air pollutions, especially benzene, have an influence on it.

    Full Text Available Abstract Background This study presents an analysis of 159 serotype 19A isolates from IPD in children before and after the general recommendation for childhood pneumococcal conjugate vaccination in Germany in July 2006. Vaccination formulations used were PCV7, PCV10 (from April 2009 and PCV13 (from Dec. 2009, replacing PCV7. Methods Isolates from invasive pneumococcal disease in children were serotyped using the Quellung reaction, tested for antibiotic susceptibility and analysed for their multi locus sequence type. Results In an analysis of 3328 isolates from invasive pneumococcal disease (IPD in children that were sent to the German National Reference Center for Streptococci between July 1997 and June 2011, we show that the proportion of 19A isolates ranged between 1.7 and 4.2% in the period 1997 to 2006. After the recommendation for pneumococcal conjugate childhood vaccination, which was issued in July 2006, the proportion of 19A isolates increased significantly to 15.0% in 2010/11. Eight clonal complexes (CC and groups accounted for 77.2% and 65.3% of all serotype 19A isolates before and after vaccination, respectively. While three CCs and several STs were not detected after vaccine introduction, four CCs and several STs first appeared after vaccination, including three ST320 isolates that could be traced to recent imports from the US, UK and India. The proportion of penicillin-nonsusceptible and of multidrug-resistant 19A isolates moderately increased after vaccine introduction. A significant increase in the use of cephalosporins and azithromycin was noted post-vaccination (p=0.00001 and p=0.0013 respectively. Conclusions The prevalence of serotype 19A in Germany has increased significantly between July 2007 and June 2011. Possible reasons for this are the introduction of pneumococcal conjugate vaccination, increased use of cephalosporins and azithromycin, import of multidrug-resistant isolates and increased reporting.

    Full Text Available Objective: This study was carried out to detect the prevalence of child abuse in three domains of physical, psychological and neglect among elementary school aged children of Qazvin Province, Iran.Methods: In this descriptive-analytic and cross-sectional study, 1028 elementary school aged children of Qazvin Province selected through multistage cluster sampling were assessed for child abuse in all domains, except for sexual abuse through a researcher-made questionnaire. The questionnaire was standardized for validity and reliability. Gathered data was statistically analyzed and P-value less than 0.05 was considered significant.Findings: Out of 1028 studied children, including 540 (52.5% boys and 488 (47.5% girls 679 (66.05% cases declared at least one type of child abuse. The number of positive cases for each domain of emotional, physical and neglect was 618 (60.1%, 360 (35% and 394 (38.3% respectively. No significance was seen regarding the gender and/or regions of living in any of the domains and total prevalence.Conclusion: Regarding the results of this study which showed a prevalence rate of 66% for child abuse; and since there are strong association between child maltreatment and its impacts in juvenile and adulthood periods in the forms of offending, mental health concerns such as suicide and homicide, substance abuse, school failure, employment difficulties, teenage pregnancy, adult attachment difficulties, family violence, intergenerational violence and so on, appropriate education to the parents, and the punishment laws for child abuse is recommended.

    Genetic variability makes influenza virus to escape the immunity and causes yearly epidemics. Monitoring those changes is necessary for vaccine selection. In addition, H3N2 viruses were considered to be seeded from Southeast Asia before spreading globally. This study described the molecular epidemiology of influenza A during the post-pandemic season 2010-2011 in Vietnam. Nasopharyngeal samples were collected from children with respiratory infections at Children's Hospital 2, Ho Chi Minh City. The HA, NA, M genes were amplified, sequenced and analyzed. Thirty-five of 1,082 (3.2%) patients were positive for influenza A, including 14 pandemic H1N1 2009 (H1N1pdm09) and 21 H3N2 infections. H3N2 was dominant in the rainy season (May-October 2010) while H1N1pdm09 was dominant in the dry season (November 2010-April 2011). Phylogenetic analysis showed that Vietnamese H1N1pdm09 sequences in 2010-2011 formed the distinct cluster, with other contemporary Asian and 2012-American sequences, suggesting a possible common ancestor. All were oseltamivir-sensitive except two strains carrying S247N and D199N in NA which reduced the neuraminidase inhibitor susceptibility. The Vietnamese H3N2 viruses in mid-2010 belonged to the emerging subclade Perth10/2010, which then spread worldwide in 2011. The Vietnamese influenza viruses were well matched with the Southern Hemisphere vaccine formulation. Mutations at antigenic sites were also identified in these viruses. Surveillance of influenza viruses in tropical countries is important not only for development of their prevention and control strategies but also for earlier identification of the newly emerged strains that may be selected for future vaccine.

    The objective of the present study is to evaluate a new diagnostic strategy using clinical findings followed by ultrasound (US) and, in selected cases, MRI. This study included 166 children presenting signs and symptoms suggesting acute appendicitis. Cases classified as suggesting appendicitis according to clinical exams had to be referred to surgery, whereas the other cases were discharged. Unclear cases were evaluated using US. If the US results were considered inconclusive, patients underwent MRI. Of the 166 patients, 78 (47%) had acute appendicitis and 88 (53%) had other diseases. The strategy under study had a sensitivity of 96 per cent, specificity of 100 per cent, positive predictive value of 100 per cent, negative predictive value of 97 per cent, and accuracy of 98 per cent. Eight patients remained undiagnosed and underwent MRI. After MRI two girls presented normal appendixes and were discharged. One girl had an enlarged appendix on MRI and appendicitis could have been confirmed by surgery. In the other five patients, no other sign of the disease was detected by MRI such as an inflammatory mass, free fluid or an abscess in the right iliac fossa. All of them were discharged after clinical observation. In the vast majority of cases the correct diagnosis was reached by clinical and US examinations. When clinical assessment and US findings were inconclusive, MRI was useful to detect normal and abnormal appendixes and valuable to rule out other abdominal pathologies that mimic appendicitis.

  6. Can a fixed measure serve as a pertinent diagnostic criterion for large vestibular aqueduct in children?

    International Nuclear Information System (INIS)

    A vestibular aqueduct midpoint width greater than 1.50 mm is currently considered to be pathognomonic for a large vestibular aqueduct syndrome. To analyse the diameter of the vestibular aqueduct in children as a function of age and consequently to determine if a fixed measure could serve as a pertinent diagnostic criterion. This was a retrospective study of 200 high-resolution CT scans of the ear in 100 patients aged 0-16 years and from various paediatric medical departments. On each CT scan, the lateral semicircular canal diameter, the vestibular aqueduct midpoint width between the external aperture and common crus, and the vestibular aqueduct external aperture diameter were measured. Spearman's rank test and the Mann-Whitney correlation test were used for an integrated statistical analysis. There was no statistically significant variability in vestibular aqueduct diameter as a function of age or sex of patients. A CT scan threshold value, fixed and independent of age and sex, is thus legitimate for the diagnosis of vestibular aqueduct dilatation. (orig.)

    After the introduction of conjugate vaccines, a strong rearrangement of pneumococcal serotypes was observed globally. Probably most concerning was the emergence of serotype 19A, which has not only high invasive disease potential, but also high antibiotic resistance. In the current study we focused on the increased prevalence of serotype 19A after the PCV vaccination rate became widely used in Hungary. A total of 2262 children aged 3-6 years were screened for pneumococcus carriage using nasal swabs. Children were divided into two groups according to the vaccination rates, low level (group 1) vs. high level (group 2). While the carriage rate did not change over time (average 32·9%), the serotype distribution differed greatly in the two groups. The prevalence of serotype 19A increased >eightfold. Almost all 19A isolates had high-level macrolide resistance and elevated penicillin minimum inhibitory concentrations. Genotyping methods revealed that these new 19A isolates are different from the previously frequent Hungary19A-6 PMEN clone. Both the carriage rate and the overall penicillin and macrolide resistance remained stable over time, but while several serotypes were represented in group 1, serotype 19A alone was clearly dominant in group 2.

    ABSTRACT OBJECTIVE To identify the prevalence of back pain among Brazilian school children and the factors associated with this pain. METHODS All 1,720 schoolchildren from the fifth to the eight grade attending schools from the city of Teutonia, RS, Southern Brazil, were invited to participate in the study. From these, 1,597 children participated. We applied the Back Pain and Body Posture Evaluation Instrument. The dependent variable was back pain, while the independent one were demographic, socioeconomic, behavior and heredity data. The prevalence ratio was estimated by multivariate analysis using the Poisson regression model (α = 0.05). RESULTS The prevalence of back pain in the last three months was 55.7% (n = 802). The multivariate analysis showed that back pain is associated with the variables: sex, parents with back pain, weekly frequency of physical activity, daily time spent watching television, studying in bed, sitting posture to write and use the computer, and way of carrying the backpack. CONCLUSIONS The prevalence of back pain in schoolchildren is high and it is associated with demographic, behavior and heredity aspects. PMID:27305406

    Background: Studies evaluating the relationship between oral health status and obesity have provided conflicting data. Therefore, there is a great need to investigate and clarify the possible connection in a comprehensive sample. Aims: To assess the relationship of obesity and oral health status among children and adolescents aged 6 to 17 years-old. Study Design: Cross-sectional study. Methods: Data were obtained from 4,534 children and adolescents (2,018 boys and 2,516 girls). Questionnaires were sent home prior to examination; afterwards, anthropometric and dental data were collected from participants. Community Periodontal Index (CPI) and number of decayed, missing, and filled teeth in the permanent dentition (DMFT), and deciduous dentition (dmft) index were used to measure oral health status. Height, body weight, body mass index (BMI), waist circumference (WC), and body fat percentage were analyzed. Results: For DMFT scores, healthy (score=0) girls and boys had significantly higher BMI and WC values than unhealthy (score>1) girls and boys (pobese) at the age of 7 (girls only), 9, 10, and 16 (boys only) years and overall (only girls) (pobesity. Obesity and dental/periodontal diseases are multifactorial diseases that follow similar risk patterns and develop from an interaction between chronic conditions originating early in life. It is important for all health professionals to educate patients at risk about the progression of periodontal and dental diseases and the importance of proper oral hygiene.

    Full Text Available From November 1996 to March 2000, a total of 884 children between 0 and 15 years, from 11 institutions including day care centres, public urban and public rural schools in Uberlândia, State of Minas Gerais, central Brazil, were examined for head louse infestation. Children's sex, race, age and some hairs characteristics were shown to be associated to parasite infestation. A prevalence rate of 35% was found and the highest rates were observed in black, female children, with long, dark, wavy hairs. Hairs density and thickness did not seem to influence significantly the distribution of this pediculosis in Uberlândia's schoolchildren. Differences observed between the prevalence rates of head lice in children from the urban institutions suggest there is a greater epidemiological heterogeneity in this group when compared to the rural schoolchildren.

    2013-05-01

    The American Psychiatric Association has revised the diagnostic criteria for their DSM-5 manual. Important changes have been made to the diagnosis of the current (DSM-IV) category of Pervasive Developmental Disorders. This category includes Autistic Disorder (autism), Asperger's Disorder, and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS). The DSM-5 deletes Asperger's Disorder and PDD-NOS as diagnostic entities. This change may have unintended consequences, including the possibility that the new diagnostic framework will adversely affect access to developmental interventions under Individuals with Disabilities Education Act (IDEA) programs, Early Intervention (for birth to 2 years olds) and preschool special education (for 3 and 4 years olds). Changing the current diagnosis of PDD-NOS to a "Social Communication Disorder" focused on language pragmatics in the DSM-5 may restrict eligibility for IDEA programs and limit the scope of services for affected children. Young children who meet current criteria for PDD-NOS require more intensive and multi-disciplinary services than would be available with a communication domain diagnosis and possible service authorization limited to speech-language therapy. Intensive behavioral interventions, inclusive group setting placements, and family support services are typically more available for children with an autism spectrum disorder than with diagnoses reflecting speech-language delay. The diagnostic distinction reflective of the higher language and social functioning between Asperger's Disorder and autism is also undermined by eliminating the former as a categorical diagnosis and subsuming it under autism. This change may adversely affect treatment planning and misinform parents about prognosis for children who meet current criteria for Asperger's Disorder. PMID:23456348

    Purpose: Non-rhabdomyosarcoma soft tissue sarcomas (NRSTS) are a heterogeneous group of sarcomas that encompass over 35 histologies. With an incidence of ∼500 cases per year in the United States in those <20 years of age, NRSTS are rare and therefore difficult to study in pediatric populations. We used the large Surveillance, Epidemiology, and End Results (SEER) database to validate the prognostic ability of the Children's Oncology Group (COG) risk classification system and to define patient, tumor, and treatment characteristics. Methods and Materials: From SEER data from 1988 to 2007, we identified patients ≤18 years of age with NRSTS. Data for age, sex, year of diagnosis, race, registry, histology, grade, primary size, primary site, stage, radiation therapy, and survival outcomes were analyzed. Patients with nonmetastatic grossly resected low-grade tumors of any size or high-grade tumors ≤5 cm were considered low risk. Cases of nonmetastatic tumors that were high grade, >5 cm, or unresectable were considered intermediate risk. Patients with nodal or distant metastases were considered high risk. Results: A total of 941 patients met the review criteria. On univariate analysis, black race, malignant peripheral nerve sheath (MPNST) histology, tumors >5 cm, nonextremity primary, lymph node involvement, radiation therapy, and higher risk group were associated with significantly worse overall survival (OS) and cancer-specific survival (CSS). On multivariate analysis, MPNST histology, chemotherapy-resistant histology, and higher risk group were significantly poor prognostic factors for OS and CSS. Compared to low-risk patients, intermediate patients showed poorer OS (hazard ratio [HR]: 6.08, 95% confidence interval [CI]: 3.53-10.47, P<.001) and CSS (HR: 6.27; 95% CI: 3.44-11.43, P<.001), and high-risk patients had the worst OS (HR: 13.35, 95% CI: 8.18-21.76, P<.001) and CSS (HR: 14.65, 95% CI: 8.49-25.28, P<.001).

    In 2013, a working group of the World Health Organization (WHO) proposed a reformulation of the posttraumatic stress disorder (PTSD) diagnostic criteria for the upcoming 11(th) edition of the International Classification of Diseases (ICD-11; Maercker, Brewin, Bryant, Cloitre, van Ommeren, et al., 2013). This study investigated the consequences of the proposed ICD-11 PTSD symptom reduction on the prevalence of PTSD in children and adolescents. Prevalence rates of PTSD in a clinical sample of 159 traumatized children and adolescents were compared applying criteria according to the 4(th) edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association, 1994), the ICD-10 (WHO, 1992), and the ICD-11. The prevalence rate was 76.1% using DSM-IV, 88.1% using ICD-10, and 61.0% using ICD-11. The use of the criteria proposed for ICD-11 resulted in 27.1% less positive cases compared with ICD-10 and 15.1% less positive cases compared with DSM-IV. Our results showed that in a clinical sample of children and adolescents the prevalence of PTSD was significantly affected by the use of different diagnostic systems. This will constitute a major challenge for research and practice because, depending on the algorithm used, different groups of patients will be included in studies and different groups of individuals will be able to access medical care and therapy.

One goal of our longitudinal study was to investigate potential risk factors for the incidence of headache (HA and back pain (BP.Methods: In the first wave (2003, questionnaires were sent to 6,400 children between the ages of 9 and 14 years. Those who answered in wave 1 were contacted again every year (four survey waves in total: 2003–2006. The data presented are based on the children's self-reports in the second wave (2004 and third wave (2005. Potential risk factors (dysfunctional stress coping, pain catastrophizing, anxiety sensitivity, and somatosensory amplification were collected in wave 2. Binary logistic regression analyses – for boys and girls – were performed to assess the predictive value of the risk factors for HA and BP in wave 3.Results: In the comprehensive model, none of the examined variables predicted the incidence of HA. Anxiety sensitivity increased the risk that boys would report BP after 1 year by 50% and dysfunctional stress coping increased the risk by 40%. For girls, somatosensory amplification increased the risk of the incidence of BP 1 year later by 80%, whereas pain catastrophizing reduced the risk by 50%.Conclusion: In this incidence sample, the amount of variance explained by the psychological variables investigated was very small. Integrating this result with existing findings from cross-sectional studies suggests that dysfunctional cognitive processing styles may develop more as a consequence or a concomitant feature of BP or HA, but play a less

    2008-11-01

    An association between birth weight weight (VLBW)) and hearing loss has been long recognised. As universal hearing screening programmes have become widely implemented and the survival rate of VLBW babies in modern intensive care units has increased, we have gained a substantially better understanding of the nature of this problem. However, many gaps in our knowledge base exist. This review describes recent data on hearing loss in the VLBW population and explains the current level of understanding about the physiological basis underlying the auditory deficits in these patients. Although VLBW alone may not have a severe impact on hearing, it is commonly associated with multiple other risk factors that can alter hearing in a synergistic fashion. Therefore, the risk of hearing loss is substantially higher than in the general newborn population. Also, it is important to perform a more comprehensive audiometric evaluation than standard otoacoustic emission screening for infants who are in the neonatal intensive care unit in order not to miss hearing loss due to retrocochlear pathology. Furthermore, children with VLBW are also at increased risk of experiencing progressive or delayed-onset hearing loss, and thus should continue to have serial hearing evaluations after discharge from the neonatal intensive care unit.

In this study we evaluated the diagnostic value of harmonin and villin autoantibodies in IPEX and IPEX-like syndromes. Harmonin and villin autoantibodies were measured by a novel Luminescent-Immuno-Precipitation-System (LIPS quantitative assay, in patients with IPEX, IPEX-like syndrome, Primary Immunodeficiencies (PID with enteropathy, all diagnosed by sequencing of the FOXP3 gene, and in type 1 diabetes (T1D, celiac disease and healthy blood donors as control groups. Harmonin and villin autoantibodies were detected in 12 (92% and 6 (46% of 13 IPEX patients, and in none of the IPEX-like, PID, T1D, celiac patients, respectively. All IPEX patients, including one case with late and atypical clinical presentation, had either harmonin and/or villin autoantibodies and tested positive for enterocyte antibodies by indirect immunofluorescence. When measured in IPEX patients in remission after immunosuppressive therapy or hematopoietic stem cell transplantation, harmonin and villin autoantibodies became undetectable or persisted at low titers in all cases but one in whom harmonin autoantibodies remained constantly high. In one patient, a peak of harmonin antibodies paralleled a relapse phase of enteropathy. Our study demonstrates that harmonin and villin autoantibodies, measured by LIPS, are sensitive and specific markers of IPEX, differentiate IPEX, including atypical cases, from other early childhood disorders associated with enteropathy, and are useful for screening and clinical monitoring of affected children.

In this work, we analyzed the characteristics of 17 common respiratory pathogens in children (≤14 years old) with ARI in Guangzhou, southern China over a 3-year period using real-time polymerase chain reaction. Pathogens were identified in 2361/4242 (55.7%) patients, and the positivity rate varied seasonally. Ten of the 17 pathogens investigated showed positivity rates of more than 5%. The most frequently detected pathogens were respiratory syncytial virus (768/2361, 32.5%), influenza A virus (428/2361, 18.1%), enterovirus (138/2361, 13.3%), Mycoplasma pneumoniae (267/2361, 11.3%) and adenovirus (213/2361, 9.0%). Co-pathogens were common and found in 503 of 2361 (21.3%) positive samples. When ranked according to frequency of occurrence, the pattern of co-pathogens was similar to that of the primary pathogens, with the exception of human bocavirus, human coronavirus and human metapneumovirus. Significant differences were found in age prevalence in 10 of the 17 pathogens (p≤0.009): four basic patterns were observed, A: detection rates increased with age, B: detection rates declined with age, C: the detection rate showed distinct peaks or D: numbers of patients were too low to detect a trend or showed no significant difference among age groups (p>0.05). These data will be useful for planning vaccine research and control strategies and for studies predicting pathogen prevalence. PMID:24797911

    Data on the economic burden of rotavirus infection in Tunisia are needed to inform the decision to include rotavirus in routine childhood immunizations. This study aimed to describe the epidemiological profile of rotavirus disease in central-east Tunisia and to estimate its hospital cost. In the first stage - the prospective collection of epidemiological data - we enrolled all patients cost data were collected retrospectively using an activity-based costing method from the medical records of the children who were positively diagnosed with rotavirus. The average cost of care per child was TD 433 (SD 134). This is a significant economic burden in Tunisia, where a safe and effective vaccine is available but not yet introduced to the immunization schedule. PMID:26446530

    In the children and adolescents of the Russian Federation, there is an increase in the incidence of a number of nosological entities, a significant prevalence of chronic diseases, and a reduction in health quality in children. According to the statistical data, in the past 5 years, the overall incidence has increased by 16% in children (aged 0-14 years) (171268 per 100,000 children in 2005) by 18% in adolescents. The incidence of diseases of blood and blood-forming organs, anemias, as well diseases of the respiratory, urogenital, and nervous systems, and congenital anomalies continues to increase. Along with socioeconomic causes, this is all due to the negative influence of environmental factors, dietary defects, and, in some cases, poor upbringing and teaching conditions, which do not comply with the hygienic standards and sanitary rules. Under the established conditions, the maintenance and improvement of children's health is the most important state task, the provision of their sanitary and epidemiological welfare being one of the major constituents in its accomplishment. In the past 3 years, the principal state sanitary inspector has issued 17 regulations on different aspects of the sanitary and epidemiological well-being of children and adolescents. The preparation of the draft "National Program for the Prevention of Adverse Health Influence of Environmental Factors for the Sake of the Future of Children and Adolescents for 2007-2010" has been currently completed. The Group of Eight Summit has noted that resolute opposition to threats of infectious diseases, the leading cause of death in the world, is vital to the global development and welfare of mankind. It has adopted the resolution that it is essential to make specific achievements in the strengthening international cooperation in the surveillance and monitoring of infectious diseases; to intensify researches; to second the efforts of appropriate international organizations, which are aimed at effectively

    Speech delay with an unknown cause is a problem among children. This diagnosis is the last differential diagnosis after observing normal findings in routine hearing tests. The present study was undertaken to determine whether auditory brainstem responses to click stimuli are different between normally developing children and children suffering from delayed speech with unknown causes. In this cross-sectional study, we compared click auditory brainstem responses between 261 children who were clinically diagnosed with delayed speech with unknown causes based on normal routine auditory test findings and neurological examinations and had >12 months of speech delay (case group) and 261 age- and sex-matched normally developing children (control group). Our results indicated that the case group exhibited significantly higher wave amplitude responses to click stimuli (waves I, III, and V) than did the control group (P=0.001). These amplitudes were significantly reduced after 1 year (P=0.001); however, they were still significantly higher than those of the control group (P=0.001). The significant differences were seen regardless of the age and the sex of the participants. There were no statistically significant differences between the 2 groups considering the latency of waves I, III, and V. In conclusion, the higher amplitudes of waves I, III, and V, which were observed in the auditory brainstem responses to click stimuli among the patients with speech delay with unknown causes, might be used as a diagnostic tool to track patients' improvement after treatment.

    Full Text Available Abstract Background Attention deficit hyperactivity disorder (ADHD is a commonly diagnosed neuropsychiatric disorder in childhood, but the frequency of the condition is not well established in many countries. The aim of the present study was to quantify the overall prevalence of ADHD among children and adolescents in Spain by means of a systematic review and meta-analysis. Methods PubMed/MEDLINE, IME, IBECS and TESEO were comprehensively searched. Original reports were selected if they provided data on prevalence estimates of ADHD among people under 18 years old in Spain and were cross-sectional, observational epidemiological studies. Information from included studies was systematically extracted and evaluated. Overall pooled-prevalence estimates of ADHD were calculated using random-effects models. Sources of heterogeneity were explored by means sub-groups analyses and univariate meta-regressions. Results Fourteen epidemiological studies (13,026 subjects were selected. The overall pooled-prevalence of ADHD was estimated at 6.8% [95% confidence interval (CI 4.9 – 8.8%] representing 361,580 (95% CI 260,550 – 467,927 children and adolescents in the community. There was significant heterogeneity (P Conclusions Our findings suggest that the prevalence of ADHD among children and adolescents in Spain is consistent with previous studies conducted in other countries and regions. This study represents a first step in estimating the national burden of ADHD that will be essential to building evidence-based programs and services.

  16. The utility of ultrasonography in the the diagnostics and monitoring of treatment of acute abdominal pain in children with neoplasms

    International Nuclear Information System (INIS)

    The aim of this study was to estimate the results of the diagnostic imaging modalities, especially ultrasonography (US) in children during the oncological therapy with the acute abdominal symptoms. Acute abdominal symptoms in children with neoplasms causing a very difficult clinical and diagnostic problems and can occur in any stage of disease. The high-resolution ultrasound has a very important role in diagnosis in all patients with acute abdominal pain and with neoplasms. The authors consider that the US should be the first imaging method in the differential diagnosis of the abdominal changes in children with neutropenia and oncological disease. Proper diagnosis should be established only with clinical information. We analyzed 249 ultrasounds examinations of the abdominal cavity in 144 girls and 105 boys aged from 1 to 18 years (mean age 10, 3 years). The more important indication for the US exam in 133 cases was acute abdominal symptoms. We took exams during pre- and postoperative chemotherapy, radiotherapy and after the hematopoietic stem cell transplantation. All the patients were under routine hematological control. Based on the clinical symptoms and the laboratory tests we analysed two groups of children with oncological disease and acute abdomen: I group - 111 children with neutropenia, II group - 22 children without neutropenia. In the patients who underwent operation procedure the final diagnosis was established on histopathology. In the other cases diagnosis was based on clinical, laboratory and radiological exams, especially ultrasonography. We analyzed clinical picture of disease, the results of therapy and the US changes in examined patients using statistic parameters as: sensitivity, specificity and efficiency. In the group of 133 children with acute abdominal symptoms the most (92- 69,1%) patients suffer from ALL (acute lymphoblastic leukaemia) and 16(12%) - from AML (acute lymphoblastic leukaemia), Ewing sarcoma-3(2,2%), osteosarcoma - 3(2,2%), NHL

    This study assessed the diagnostic approaches of Helicobacter pylori (IP)-associated iron deficiency (ID) and anemia (IDA) in children with dyspeptic symptoms and evaluated the effect of simultaneous anti-H. pylori (anti-HIP) therapy and oral iron in comparison with each of anti? HP therapy and oral iron therapy alone, on iron status as assessed by serum soluble transferrin receptor (sTfR) level. Two hundreds children with dyspeptic symptoms were subjected to clinical evaluation, stool examination, CBC, biochemical assays for serum iron parameters and measurements of serum IgG antibodies to HP and serum sTfR level by ELISA. Sixty children were found to have HP. associated ID or IDA and were randomly divided into 3 groups (20 children each). GA received 2-week anti-HP therapy plus 90-day oral iron, and GB received 2-week anti-HP therapy alone whereas group C received 90-day oral iron alone. Re-evaluation of the 3 groups was performed after 3 months of treatment initiation by repeat CBC and serum sTfR level. Children (45%) were HP-seropositive. The mean values of serum sTfR were significantly higher in HP-positive group and in HP-positive children with IDA than in HP-negative group and in HP-negative children with IDA although no significant differences were noted in hematologic variables and iron parameters between the corresponding groups and children. As regard treatment groups, there were significant improvements in the mean values of indices of IDA status (HIb, MCH, MCV, sTfR) and ID status (sTtRi) at 3 months of treatment initiation compared with their baseline values after. anti-HP triple therapy either with oral iron or without oral iron whereas the control children who were treated with oral iron alone showed insignificant changes despite oral iron administration. The improvements in these parameters were significantly greater in groups of children who received anti-HP therapy either combined with iron or alone, where compared with those who did not receive

    Full Text Available Abstract Background The clinical management of community-acquired respiratory tract infections (RTIs is complicated by the increasing worldwide prevalence of antibacterial resistance, in particular, β-lactam and macrolide resistance, among the most common causative bacterial pathogens. This study aimed to determine the mechanisms and molecular- and sero-epidemiology of antibacterial resistance among the key paediatric respiratory pathogens in Japan. Methods Isolates were collected at 18 centres in Japan during 2002 and 2003 from children with RTIs as part of the PROTEKT surveillance programme. A proportion of Haemophilus influenzae isolates was subjected to sequencing analysis of the ftsI gene; phylogenetic relatedness was assessed using multilocus sequence typing. Streptococcus pneumoniae isolates were screened for macrolide-resistance genotype by polymerase chain reaction and serotyped using the capsular swelling method. Susceptibility of isolates to selected antibacterials was performed using CLSI methodology. Results and Discussion Of the 557 H. influenzae isolates collected, 30 (5.4% were β-lactamase-positive [BL+], 115 (20.6% were BL-nonproducing ampicillin-resistant (BLNAR; MIC ≥ 4 mg/L and 79 (14.2% were BL-nonproducing ampicillin-intermediate (BLNAI; MIC 2 mg/L. Dabernat Group III penicillin binding protein 3 (PBP3 amino acid substitutions in the ftsI gene were closely correlated with BLNAR status but phylogenetic analysis indicated marked clonal diversity. PBP mutations were also found among BL+ and BL-nonproducing ampicillin-sensitive isolates. Of the antibacterials tested, azithromycin and telithromycin were the most active against H. influenzae (100% and 99.3% susceptibility, respectively. A large proportion (75.2% of the 468 S. pneumoniae isolates exhibited macrolide resistance (erythromycin MIC ≥ 1 mg/L; erm(B was the most common macrolide resistance genotype (58.8%, followed by mef(A (37.2%.

    In response to a widespread belief within the legal system that cross-examination is instrumental in uncovering the truth, we examined the effect of cross-examination questioning on the reports of children who had-and had not-been coached to lie. A group of children, aged 6-11 years (N = 65), played three computer games with one of their parents. For half of the pairs, the parents-who acted as confederates-coached their children to make lies of commission concerning the occurrence of two target activities. For the remaining pairs, these two target activities actually occurred, and there was no coaching. Immediately afterwards, children were interviewed about the two activities. Those who-correctly or incorrectly-reported that both activities occurred were retained for the final sample (n = 56); these children were then interviewed again with both neutral questions and cross-examination-style challenges. Neither style of questioning elicited responses that discriminated between liars and truth-tellers: although the accuracy of children who were lying increased in response to cross-examination questions, the accuracy of truth-telling children saw a corresponding decrease. When asked neutral questions, children's responses tended to be consistent with their earlier responses, whether or not those responses were lies. These findings raise important questions about the function that cross-examination might serve in trials involving child witnesses. Copyright © 2016 John Wiley & Sons, Ltd. PMID:27117604

    International Nuclear Information System (INIS)

    Aim: To compare the diagnostic accuracy of non-invasive cerebral post-mortem magnetic resonance imaging (PMMRI) specifically for cerebral and neurological abnormalities in a series of fetuses and children, compared to conventional autopsy. Materials and methods: Institutional ethics approval and parental consent was obtained. Pre-autopsy cerebral PMMRI was performed in a sequential prospective cohort (n = 400) of fetuses (n = 277; 185 ≤ 24 weeks and 92 > 24 weeks gestation) and children <16 years (n = 123) of age. PMMRI and conventional autopsy findings were reported blinded and independently of each other. Results: Cerebral PMMRI had sensitivities and specificities (95% confidence interval) of 88.4% (75.5 to 94.9), and 95.2% (92.1 to 97.1), respectively, for cerebral malformations; 100% (83.9 to 100), and 99.1% (97.2 to 99.7) for major intracranial bleeds; and 87.5% (80.1 to 92.4) and 74.1% (68 to 79.4) for overall brain pathology. Formal neuropathological examination was non-diagnostic due to maceration/autolysis in 43/277 (16%) fetuses; of these, cerebral PMMRI imaging provided clinically important information in 23 (53%). The sensitivity of PMMRI for detecting significant ante-mortem ischaemic injury was only 68% (48.4 to 82.8) overall. Conclusions: PMMRI is an accurate investigational technique for identifying significant neuropathology in fetuses and children, and may provide important information even in cases where autolysis prevents formal neuropathological examination; however, PMMRI is less sensitive at detecting hypoxic–ischaemic brain injury, and may not detect rarer disorders not encountered in this study. -- Highlights: •Post mortem MRI (PMMRI) has a sensitivity of >87% for detecting cerebral malformations, intracranial bleeds and neurological cause of death. •PMMRI provides important diagnostic information in >50% of fetuses where conventional brain autopsy is non-diagnostic. •PMMRI is currently poor at reliably identifying

    The Influenza Complications Alert Network (FluCAN) is a sentinel hospital-based surveillance programme operating in all states and territories in Australia. We summarise the epidemiology of children hospitalised with laboratory-confirmed influenza in 2014 and reports on the effectiveness of inactivated trivalent inactivated vaccine (TIV) in children. In this observational study, cases were defined as children admitted with acute respiratory illness (ARI) with influenza confirmed by PCR. Controls were hospitalised children with ARI testing negative for influenza. Vaccine effectiveness (VE) was estimated as 1 minus the odds ratio of vaccination in influenza positive cases compared with test-negative controls using conditional logistic regression models. From April until October 2014, 402 children were admitted with PCR-confirmed influenza. Of these, 28% were aged < 1 year, 16% were Indigenous, and 39% had underlying conditions predisposing to severe influenza. Influenza A was detected in 90% of cases of influenza; influenza A(H1N1)pdm09 was the most frequent subtype (109/141 of subtyped cases) followed by A(H3N2) (32/141). Only 15% of children with influenza received antiviral therapy. The adjusted VE of one or more doses of TIV for preventing hospitalised influenza was estimated at 55.5% (95% confidence intervals (CI): 11.6-77.6%). Effectiveness against influenza A(H1N1)pdm09 was high (91.6% , 95% CI: 36.0-98.9%) yet appeared poor against H3N2. In summary, the 2014 southern hemisphere TIV was moderately effective against severe influenza in children. Significant VE was observed against influenza A(H1N1)pdm09. PMID:27494798

    In recent years, the isolation of parasitic DNA from faecal samples and PCR techniques, have been improved and simplified. Moreover, the introduction of real-time PCR has made it possible to multiplex different targets into one reaction. These new technical possibilities make it feasible to introduce PCR with its unsurpassed sensitivity and specificity in a routine laboratory setting for the diagnosis of intestinal parasites. Detection rates of the parasitic infections included in the PCR are increased significantly compared with microscopy. Molecular diagnostics, especially in children, reveal a possible cause of the gastrointestinal complaints in many more cases compared with conventional methods. Usually in GP patients no other pathogenic parasites are detected using microscopy and in the returning travellers additional parasites are found with microscopy in a minority of cases only. Multiplex real-time PCR offers a highly sensitive and specific diagnostic alternative for labour intensive microscopy in clinical laboratory practice. Additional diagnostic methods for the detection of parasitic infections that are not included as PCR target can be limited to a selected group of patients. PMID:21859503

    Fine-needle aspiration (FNA) is commonly used to diagnose skin disease in companion animals, but its use in horses appears to be infrequent. Equine veterinarians in western Canada were surveyed to determine their opinions about FNA and 15 years of diagnostic submissions were used to compare the perceived to actual value of FNA in the diagnosis of skin disease in horses. Practitioners viewed FNA as quick, easy, economical, and minimally invasive. However, most veterinarians rarely chose to use FNA due to a perception that sample quality and diagnostic yield were poor and there was a narrow range of diseases the technique could diagnose. Analysis of the FNA cytology samples from a veterinary diagnostic laboratory showed a wide variety of equine skin disease conditions, but the frequency of non-diagnostic results was significantly higher in equine submissions compared to those from dogs and cats.

    The epidemiology of laboratory-confirmed respiratory syncytial virus (RSV) infections in young children has not recently been described in England, and is an essential step in identifying optimal target groups for future licensed RSV vaccines. We used two laboratory surveillance systems to examine the total number and number of positive RSV tests in children aged <5 years in England from 2010 to 2014. We derived odds ratios (ORs) with 95% confidence intervals (CIs) comparing children by birth month, using multivariable logistic regression models adjusted for age, season and sex. Forty-seven percent of RSV tests (29 851/63 827) and 57% (7405/13 034) of positive results in children aged <5 years were in infants aged <6 months. Moreover, 38% (4982/13 034) of positive results were in infants aged <3 months. Infants born in September, October and November had the highest odds of a positive RSV test during their first year of life compared to infants born in January (OR 2·1, 95% CI 1·7-2·7; OR 2·4, 95% CI 2·1-2·8; and OR 2·4, 95% CI 2·1-2·7, respectively). Our results highlight the importance of young age and birth month near the beginning of the RSV season to the risk of laboratory-confirmed RSV infection. Future control measures should consider protection for these groups. PMID:26916807

A monthly injection of palivizumab has been used for prophylaxis of serious RSV infections among high-risk children in 71 countries since 1998 and approval for use in the Russian Federation was obtained in February 2010. A recommendation for RSV prophylaxis in the Russian Federation would require knowledge of the prevalence and seasonality of RSV in that country.Methods: In a prospective, multicenter, epidemiological study of the prevalence, seasonality, and peak occurrence of RSV infection, children aged ≤2 years hospitalized for lower respiratory tract infections in three regions of the Russian Federation, from September 2008 through April 2009, were screened and tested for RSV using rapid immunochromatography of nasopharyngeal lavage. For subjects who were tested positive, hospitalization data were collected.Results: Of 519 children aged ≤2 years enrolled from September 11, 2008 through April 26, 2009, 197 tested positive for RSV (38.0%, 95% CI: 33.8, 42.3. The onset of the 2008–2009 RSV season in the Russian Federation occurred in late October 2008, similar to what is observed in other northern temperate zones. Peak activity occurred in early April 2009, when 62% of children enrolled tested positive for RSV.Conclusion: The prevalence

    International Nuclear Information System (INIS)

    To determine, in a systematic review, the diagnostic accuracy, acceptability and cost-effectiveness of less invasive autopsy by post-mortem MR imaging, in fetuses, children and adults. We searched Medline, Embase, the Cochrane library and reference lists to identify all studies comparing post-mortem MR imaging with conventional autopsy, published between January 1990 and March 2009. 539 abstracts were identified; 15 papers met the inclusion criteria; data from 9 studies were extracted (total: 146 fetuses, 11 children and 24 adults). In accurately identifying the final cause of death or most clinically significant abnormality, post-mortem MR imaging had a sensitivity and specificity of 69% (95% CI-56%, 80%) and 95% (95% CI-88%, 98%) in fetuses, and 28% (95% CI-13%, 47%) and 64% (95% CI-23%, 94%) in children and adults, respectively; however the published data is limited to small, heterogenous and poorly designed studies. Insufficient data is available on acceptability and economic evaluation of post-mortem MR imaging. Well designed, large, prospective studies are required to evaluate the accuracy of post-mortem MR imaging, before it can be offered as a clinical tool.

  16. Is the propagation speed of ultrasound in human organs a diagnostic parameter for tissue characterization? Evaluation using the liver parenchyma in children and adolescents as an example

    International Nuclear Information System (INIS)

    New sonographic machines permit the measurement of the propagation speed of ultrasound (PSU) in humans. The liver seems to be an appropriate organ for examining whether the PSU may be used as a diagnostic parameter for tissue characterization since the liver is easily accessible to sonography and its variable content of fat impacts the PSU. Purpose: To determine whether there is a measurable correlation between obesity and PSU in the liver. Methods: In 69 children and adolescents, the PSU in the liver was measured sonographically and correlated to BMI, age, size and weight of the children. Results: A strong correlation was found between the PSU in the liver and the BMI. The PSU was significantly lower in obese children (1507 m/s) than in children with normal body weight (1564 m/s). Conclusion: PSU seems to be promising as an additional diagnostic parameter for characterizing liver tissue. Further evaluation is necessary. (orig.)

    Although children may dislike and/or resist oral and pharyngeal examination with a tongue depressor, they enjoy lollipops on sticks, eating with spoons, forks, and chopsticks, and brushing their teeth. Many reports have noted this apparent contradiction, since paediatric patients are often treated after toothbrushes or chopsticks penetrate the pharyngeal wall. We therefore developed a novel device to observe the inside of the mouth without using a flashlight, tongue depressor or head mirror. We previously developed the AWS for tracheal intubation through the mouth for anaesthesia and emergency situations, along with a new device to observe the inside of the oral cavity simultaneously. We have developed a new attachment to the AWS for observations inside the oral cavity and pharynx. Our newly developed oral and pharyngeal examination system is a useful tool for diagnostic examinations and may also enable treatment without causing discomfort or distress to patients and their families.

    Diagnosis of intra-articular lesions in children based on clinical examination and MRI is particularly challenging. To evaluate the diagnostic performance of MRI and pre-surgical evaluation of the knee in pediatric patients relative to arthroscopic evaluation as the gold standard. We report diagnoses frequently missed or inaccurately diagnosed pre-operatively. We conducted a retrospective review of MRI and pre-surgical evaluation in children and adolescents ages 1-17 years who were treated by knee arthroscopy during a 21/2-year period. All MRIs were reviewed by a pediatric radiologist blinded to clinical findings. Pediatric orthopedic clinic notes were reviewed for pre-surgical evaluation (based on physical exam, radiograph, MR images and radiologist's MRI report). Arthroscopic findings were used as the gold standard. We calculated the percentages of diagnoses at arthroscopy missed on both MRI and pre-surgical evaluation. Diagnostic accuracy between children and adolescents and in patients with one pathological lesion vs. those with >1 lesion was analyzed. We performed a second review of MR images of the missed or over-called MRI diagnoses with knowledge of arthroscopic findings. We included 178 children and adolescents. The most common diagnoses missed on MRI or pre-surgical evaluation but found at arthroscopy were: discoid meniscus (8/30, or 26.7% of cases); lateral meniscal tears (15/80, or 18.8% of cases); intra-articular loose bodies (5/36, or 13.9% of cases), and osteochondral injuries (9/73, or 12.3% of cases). Overall diagnostic accuracy of MRI and pre-surgical evaluation was 92.7% and 95.3%, respectively. No significant difference in diagnostic accuracy between children and adolescents was observed. When multiple intra-articular lesions were present, lateral meniscal tears were more likely to be inaccurately diagnosed (missed or over-called) on both MRI (P = 0.009) and pre-surgical evaluation (P < 0.001).

  11. Diagnostic role of initial renal cortical scintigraphy in children with the first episode of acute pyelonephritis

    International Nuclear Information System (INIS)

    Assessment of the first febrile urinary tract infection (UTI) in children has been the subject of debate for many years. Diagnosis of acute pyelonephritis (APN) is usually based on clinical and biological data. The clinical usefulness of early Tc-99m dimercaptosuccinic acid (DMSA) scintigraphy remains controversial, although it may influence the type and duration of treatment. The aim of this study was to assess the role of initial cortical scintigraphy in the detection of early renal parenchymal damage in children highly suspected of having APN and to compare the scintigraphic findings with selected clinical/laboratory parameters and ultrasonography. A prospective study was conducted in 34 infants and young children (18 boys, 16 girls), aged 1.5-36 months (mean 9.8±8.7 months), hospitalized with a first episode of clinically suspected APN. Within the first 5 days after admission, Tc-99m DMSA renal scintigraphy, ultrasonography (US), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), white blood cell count (WBC) and urine analyses were performed. DMSA scintigraphy showed changes consistent with APN in 27/34 (79%) patients, with a mean age of 10.9 months, including 12 males (44%) and 15 (56%) females. Out of 9 febrile children with negative urine culture and supportive evidence of UTI, scintigraphy showed parenchymal involvement in 8 children (24% in the whole group, 30% in scintigraphically documented APN). There were no statistically significant correlations between the frequency or size of the initial scintigraphic abnormalities and age, sex, body temperature, CRP levels or ESR. A CRP level of >54 mg/L and a WBC of >13,300/mm3 had sensitivities of 56 and 59% and specificities of 86 and 71%, respectively. US showed changes consistent with APN in 7/34 (21%) in the whole group and in 7/27 (26%) patients with positive cortical scan (p<0.05). Initial DMSA renal scintigraphy is a sensitive method for the early diagnosis of APN in young children and is

    Full Text Available Objectives: Obtaining a diagnosis of an Autism Spectrum Disorder (ASD for a child is a pivotal point in developing the treatment plan for the child but can also be regarded as highly stressful by parents. The current study examined the impact of different aspects of the diagnosis process on the self-reported mental health of mothers of children undergoing a diagnosis for ASD in a cross-sectional cohort design. Methods: One-hundred-fifty-eight mothers of consequently diagnosed children with ASD participated. The severity of the children’s ASD and their intellectual functioning was assessed within twelve months of the diagnosis, and the mothers completed a psychometric assessment battery including the Hospital Anxiety and Depression Scale, General Health Questionnaire, and Questionnaire on Resources and Stress. Results: The actual time from first reporting a problem to obtaining a diagnosis, and the speed of the diagnostic process from first to last appointment, were both negatively related to patenting stress. In contrast, mothers’ perceptions of the speed and helpfulness of the process were negatively related to levels of anxiety and depression. The number of professionals involved in the process and the perceived coherence of the diagnosis were also negatively related to aspects of mothers’ functioning. Conclusions: Care is needed to help mothers through the diagnostic process with regard to their own functioning. Providing information and help sources throughout the process, while keeping the number of professionals involved to a minimum, may improve the parent perception of the process and reduce the negative impacts of the diagnosis on the family as a whole.

To provide a state of the art on diagnostics, clinical characteristics, and treatment of paediatric generalised joint hypermobility (GJH and joint hypermobility syndrome (JHS. Method. A narrative review was performed regarding diagnostics and clinical characteristics. Effectiveness of treatment was evaluated by systematic review. Searches of Medline and Central were performed and included nonsymptomatic and symptomatic forms of GJH (JHS, collagen diseases. Results. In the last decade, scientific research has accumulated on all domains of the ICF. GJH/JHS can be considered as a clinical entity, which can have serious effects during all stages of life. However research regarding the pathological mechanism has resulted in new potential opportunities for treatment. When regarding the effectiveness of current treatments, the search identified 1318 studies, from which three were included (JHS: n=2, Osteogenesis Imperfecta: n=1. According to the best evidence synthesis, there was strong evidence that enhancing physical fitness is an effective treatment for children with JHS. However this was based on only two studies. Conclusion. Based on the sparsely available knowledge on intervention studies, future longitudinal studies should focus on the effect of physical activity, fitness, and joint stabilisation. In JHS and chronic pain, the effectiveness of a multidisciplinary approach should be investigated.

    Background Illegal plasma collecting activities in mid 1990s caused a large number of human immunodeficiency virus (HIV) infections in rural areas of central-eastern China. Although most of these activities have been stopped, there were few reports on secondary transmission from infected former plasma donors to their spouses and from infected mothers to their children. This study was to determine the extent of HIV infections among young children in a rural community with a large proportion of plasma donors.Methods A survey was conducted among children aged under 7 years in a former plasma donating community in September 2000: finger blood was collected for HIV antibody testing. Another survey was repeated among children aged under 8 years and their families in the same community in April 2001: urine samples were collected for HIV testing. HIV positive children and samples of HIV negative children, whose mothers were positive based on 2001 survey, were followed up until September 2002 to investigate HIV seroconversion, disease progression and HIV strain analysis. Questionnaires were administered to collect information on children's delivery, breast feeding, medical history and their parents' commercial blood donation history and HIV status.Results Among 169 children surveyed in 2000, 10 (5.9%) were HIV positive. Of 224 children, 11 were positive in 2001. The overall prevalence rate in the two surveys was 5.0% (17/337) when counting 56 repeated children only once. Of children born to HIV positive mothers, 28.9% were infected. A seroconversion rate of 2.5 per 100 child-years was observed by following up 28 HIV negative children. No statistically significant associations were found between children's HIV infection and their histories of blood transfusion, surgery, immunization injection or medical injections. All infections were HIV-1 subtype B' strain, the average dispersion rate is 7.4%. DNA sequence analysis showed a close relationship between the seroconverted

    Full Text Available Meningitis is a formidable illness with high mortality and morbidity in India. Delay in distinguishing pyogenic meningitis from tuberculous and viral meningitis and delay in starting therapy on one hand and irrational use of antibiotics on the other hand may have irrevocable consequences, so, early diagnosis and appropriate treatment of pyogenic meningitis is very vital to prevent permanent neurological deficits. Detection of C-reative protein in CSF is a bed side rapid diagnostic test to distinguish pyogenic from tuberculous and viral meningitis. So, present study was undertaken to study the usefulness of c-reactive protein in CSF as a rapid diagnostic test in differentiating pyogenic from tuberculous and viral meningitis.This study was conducted at Smt Shardaben Hospital from Sept-2008 to Nov-2010. Total 150 cases admitted in paediatric department and neonates admitted to the sick nursery suspected of having meningitis were included. Samples of CSF were taken for bed side diagnostic test of CSF-CRP. The major advantage of this method is rapid two minute reaction time. Our study revealed that out of 150 cases of suspected meningitis 64 (42.66% patient were having meningitis out of which 18 (12% patients were diagnosed as pyogenic meningitis and CSF CRP was positive in 10 (55.55 % patients out of 18 pyogenic meningitis patients and CSF-CRP was negative in all other groups Applying chisquare test, correlation between CSF-CRP positivity and pyoganic meningitis was highly significant (x2 = 31(i.e.> 3.84

    The incidence of Kawasaki disease in Maghreb countries is apparently low, unlike those living in the province of Quebec, Canada. This retrospective study compared Maghrebi children living in Quebec to the countries of origin, Morocco, Algeria, and Tunisia. The annualized incidence rate in Quebec (18.49/year/100 000 children under 5 years of age) was 4 to 12 times higher than in Tunisia, Morocco, and Algeria (0.95, 4.52, and 3.15, respectively). The prevalence of incomplete diagnostic criteria was higher in Quebec at 39%, Morocco 43%, and Tunisia 39% compared to Algeria at 8%, with minimal delayed diagnosis (7%) only in Quebec compared to 30%, 35%, and 62%, respectively (P countries of origin seems due to underdiagnosis, which represents a public health concern in those countries.

  19. Cancer incidence rate after diagnostic X-ray exposure in 1976-2003 among patients of a university children's hospital

    International Nuclear Information System (INIS)

    Purpose: Although the carcinogenic effect of ionizing radiation is well known, knowledge gaps persist on the health effects of low-dose radiation, especially in children. The cancer incidence rate in a cohort of 92,957 children diagnosed using X-rays in the years 1976-2003 in the radiology department of a large university clinic was studied. Materials and Methods: Individual radiation doses per examination were reconstructed using an algorithm taking into account the dose area product and other exposure parameters together with conversion factors computed specifically for the equipment and protocols used in the radiology department. Incident cancer cases in the period 1980-2006 were identified via record linkage to the German Childhood Cancer Registry using pseudonymized data. Results: A total of 87 cancers occurred in the cohort between 1980 and 2006: 33 leukemia, 13 lymphoma, 10 brain tumors, and 31 other tumors. The standardized incidence ratio (SIR) for all cancers was 0.99 (95 % CI: 0.79 1.22). A dose-response relationship was not observed for all cancers, leukemia and lymphoma or solid tumors. The cancer risks for boys and girls did not differ. Conclusion: No increase in the cancer incidence risk in relation to very low doses of diagnostic ionizing radiation was observed in this study. However, the results are compatible with a broad range of risk estimates. (orig.)

    Full Text Available Problem statement: Considering high prevalence of gastrointestinal complaints in children and the important role of endoscopy in the diagnosis of such complaints, this study was designed to characterize the clinical, endoscopic and pathologic features of Iranian children undergoing upper Gastrointestinal (GI endoscopy. Approach: This prospective study was performed in an office-based setting in a private medical centre in Kerman, Iran, between December 2004 to January 2008. Three hundred forty pediatric patients who underwent upper endoscopy for dyspeptic symptoms or other reasons were enrolled into this study and data were gathered concerning age, sex, reason of endoscopy, endoscopy report and pathologic report. Upper GI endoscopy was performed using Pentax video endoscope. Results: The most prevalent reason of performing endoscopy (43.1% was abdominal pain. More than half of the cases with abdominal pain (54% were in the age range of 5-10 year old of whom 80% had an abnormal pathologic finding such as esophgitis and active chronic gastritis associated with helicobacter pylori. The most common endoscopic finding (31.2% and pathologic finding (40.3% was esophagitis. More than half of the children with esophagitis (56.6% had some degrees of hiatal hernia. In 35.5% of children with nodular gastritis, simultaneous esophagitis was observed. The rate of normal endoscopies and pathologies were respectively 10.8 and 19.4%. Conclusion: Considering low rate of normal endoscopic and pathologic reports in the studied subjects and also the variety of gastrointestinal complaints in them, it seems that proper selection of patients for undergoing upper GI endoscopy can have a significant directive role in the diagnosis of pediatric problems.

    2013-07-01

    The purpose of this study was to investigate health and annoyance reactions to change in chronic exposure to aircraft noise on a sample of South African children. It was the intention of this study to examine if effects of noise on health and annoyance can be demonstrated. If so, whether such effects persist over time, or whether such effects are reversible after the cessation of exposure to noise. A cohort of 732 children with a mean age of 11.1 (range = 8-14) participated at baseline measurements in Wave 1 (2009), and 649 (mean age = 12.3; range = 9-15) and 174 (mean age = 13.3; range = 10-16) children were reassessed in Wave 2 (2010) and Wave 3 (2011) after the relocation of the airport, respectively. The findings revealed that the children who were exposed to chronic aircraft noise continued to experience significantly higher annoyance than their counterparts in all the waves at school, and only in Wave 1 and Wave 2 at home. Aircraft noise exposure did not have adverse effects on the children's self-reported health outcomes. Taken together, these findings suggest that chronic exposure to aircraft noise may have a lasting impact on children's annoyance, but not on their subjective health rating. This is one of the first longitudinal studies of this nature in the African continent to make use of an opportunity resulting from the relocation of airport. PMID:23823713

    Full Text Available BACKGROUND: Advances in molecular diagnostics have implicated newly-discovered respiratory viruses in the pathogenesis of pneumonia. We aimed to determine the prevalence and clinical characteristics of human bocavirus (hBoV, human rhinovirus (hRV, polyomavirus-WU (WUPyV and -KI (KIPyV and human coronaviruses (CoV-OC43, -NL63, -HKU1 and -229E among children hospitalized with lower respiratory tract infections (LRTI. METHODS: Multiplex real-time reverse-transcriptase polymerase chain reaction was undertaken on archived nasopharyngeal aspirates from HIV-infected and -uninfected children (<2 years age hospitalized for LRTI, who had been previously investigated for respiratory syncytial virus, human metapneumovirus, parainfluenza I-III, adenovirus and influenza A/B. RESULTS: At least one of these viruses were identified in 274 (53.0% of 517 and in 509 (54.0% of 943 LRTI-episodes in HIV-infected and -uninfected children, respectively. Human rhinovirus was the most prevalent in HIV-infected (31.7% and -uninfected children (32.0%, followed by CoV-OC43 (12.2% and hBoV (9.5% in HIV-infected; and by hBoV (13.3% and WUPyV (11.9% in HIV-uninfected children. Polyomavirus-KI (8.9% vs. 4.8%; p = 0.002 and CoV-OC43 (12.2% vs. 3.6%; p<0.001 were more prevalent in HIV-infected than -uninfected children. Combined with previously-tested viruses, respiratory viruses were identified in 60.9% of HIV-infected and 78.3% of HIV-uninfected children. The newly tested viruses were detected at high frequency in association with other respiratory viruses, including previously-investigated viruses (22.8% in HIV-infected and 28.5% in HIV-uninfected children. CONCLUSIONS: We established that combined with previously-investigated viruses, at least one respiratory virus was identified in the majority of HIV-infected and HIV-uninfected children hospitalized for LRTI. The high frequency of viral co-infections illustrates the complexities in attributing causality to specific viruses

    Epidemiology is the study of disease distribution and factors determining or affecting it. Likewise, endodontic epidemiology can be defined as the science of studying the distribution pattern and determinants of pulp and periapical diseases; specially apical periodontitis. Although different study designs have been used in endodontics, researchers must pay more attention to study designs with higher level of evidence such as randomized clinical trials.

  12. The role of MRI in diagnostic algorithm of cervicofacial vascular anomalies in children

    International Nuclear Information System (INIS)

    Vascular anomalies are usually diagnosed through their clinical picture and history. The purpose of this study was to assess the role of MR imaging in initial assessment of cervicofacial vascular anomalies in children. Twenty pediatric patients with vascular anomalies located in the cervicofacial region underwent MRI examination in our department. Images were evaluated for lesion detectability and its signal characteristics (on T1w, T2w images with fat suppression and contrast enhanced T1w sequences); the extent of the lesions and surrounding tissue involvement were also assessed. In the studied group MR images revealed all anomalies and provided information of their anatomic extent and invasion of surrounding anatomic structures. Nine hemangiomas and six venous malformations were found among studied patients. Two children had multiloculated lesions corresponding to lymphatic malformations. One examination visualized a lesion consisting mainly of dilated vascular channels with an apparent feeding artery, which was consistent with arteriovenous malformation. Two remaining lesions were mixed malformations. Nine patients had lesions limited to subcutaneous tissue. Two masses infiltrated bone structures. There was muscle involvement found in nine cases. MR imaging is a well-established method for detection and monitoring of vascular anomalies in children. With ultrasound used mostly for initial diagnosis and additional flow assessment, angiography viewed as an invasive therapeutic method and computed tomography used only in specific situations due to its high irradiation dose, magnetic resonance is the best imaging method used in differential diagnosis and topographical characterization of vascular malformations and tumors of cervicofacial area in pediatric patients. Noninvasively and without irradiation, it enables evaluation of the extent and characteristics of lesions and planning proper therapeutic strategy

  13. Acute lymphoblastic leukemia in very young children. Diagnostic and therapeutic aspects of 43 cases

    International Nuclear Information System (INIS)

    Between 1974 and 1982, 43 children less than 2 years of age were treated in the hematology department of Hospital Saint-Louis for acute lymphoblastic leukemia (ALL). Of the patients who presented before 18 months of age, 80% had a WBC greater than 100,000 microliter and/or a great tumor bulk. As a result of our experience, treatment regimens have been changed here from conventional chemotherapy to a very intensive program with a heavy induction (vincristine, daunorubicin, cyclophosphamide, prednisone, and L-asparaginase) and monthly reinductions with the same drugs plus ArA-C, without maintenance. Prophylaxis included CNS irradiation (16-24 Gy) after 12 months of age, plus intrathecal methotrexate. Complete remission (CR) occurred in 78% before 18 months and in 100% between 18 and 24 months of age at diagnosis. In this report the probability of a prolonged CR (33% at 2 years) was the same before and after 12 months of age. However, younger patients were more intensively treated. The prognosis for children less than 1 year of age who received very intensive chemotherapy has greatly improved, with a significantly higher probability of long CR (p less than 0.02). Presently, 10 of 43 children are in CR 27 months to 8 years after diagnosis. Of 18 patients aged less than 1 year at diagnosis, four are in CR. No relapse occurred after 23 months. None of these patients presented with important sequellae, with the exception of one child who suffered from severe bacterial meningitis. An aggressive chemotherapy program is indicated in patients less than 2 years of age. The feasibility of this mode of treatment in young patients is possible only with the help of specific supportive care

    International Nuclear Information System (INIS)

    Amebiasis, infection with the protozoan Entamoeba histolytica, affects at least 10% of the world's population, with an incidence exceeding 30% in tropical and subtropical regions. Amebic liver abscess (ALA) is the most common extraintestinal form of invasive amebiasis and is a serious life-threatening disease in children. Recent experience indicates the prognosis of ALA in childhood to be improved with early identification of abscesses and prompt institution of treatment. The authors incorporate experience with a case of ALA in infancy with a review of current literature (1974-1983) to delineate clinical and radiologic features of ALA in childhood and further define the role of hepatic imaging in the diagnosis and treatment

    Khabibulla Aminov

    2015-12-01

    Full Text Available In this article the possibilities of MR tractography in symptomatic epilepsy patients have been presented. We determined the quantitative standards of numerical values of diffusion of white matter in children with symptomatic epilepsy of various etiology. In children with symptomatic epilepsy, the pathological changes of white matter were localized not only in the epileptogenic, but also in the opposite hemisphere. The regions with abnormal white matter FA and ADC values not only matched to limbic circle zones, but also to areas of intra- and interhemispheric connections uniting the frontal, temporal, parietal and occipital lobes of the brain. Determining the specific clusters of brain tracts in symptomatic epilepsy, regardless of etiology, is important to predict the prognosis of the disease and the likely possibility of cognitive impairment. The study proved that symptomatic epilepsy is characterized by a variety of changes in the white matter of the brain tracts that lead to the dissociation of certain regions of the brain, interrupting connections between cortical and subcortical regions and inhibiting the transfer of information. It can be concluded, that diffusion-weighted imaging are much more sensitive to the structural and metabolic changes occurring in the brain, in comparison with conventional MRI images.

    Full Text Available Abstract Background Urinary tract infection (UTI is common in children, and may cause serious illness and recurrent symptoms. However, obtaining a urine sample from young children in primary care is challenging and not feasible for large numbers. Evidence regarding the predictive value of symptoms, signs and urinalysis for UTI in young children is urgently needed to help primary care clinicians better identify children who should be investigated for UTI. This paper describes the protocol for the Diagnosis of Urinary Tract infection in Young children (DUTY study. The overall study aim is to derive and validate a cost-effective clinical algorithm for the diagnosis of UTI in children presenting to primary care acutely unwell. Methods/design DUTY is a multicentre, diagnostic and prospective observational study aiming to recruit at least 7,000 children aged before their fifth birthday, being assessed in primary care for any acute, non-traumatic, illness of ≤ 28 days duration. Urine samples will be obtained from eligible consented children, and data collected on medical history and presenting symptoms and signs. Urine samples will be dipstick tested in general practice and sent for microbiological analysis. All children with culture positive urines and a random sample of children with urine culture results in other, non-positive categories will be followed up to record symptom duration and healthcare resource use. A diagnostic algorithm will be constructed and validated and an economic evaluation conducted. The primary outcome will be a validated diagnostic algorithm using a reference standard of a pure/predominant growth of at least >103, but usually >105 CFU/mL of one, but no more than two uropathogens. We will use logistic regression to identify the clinical predictors (i.e. demographic, medical history, presenting signs and symptoms and urine dipstick analysis results most strongly associated with a positive urine culture result.

METHODS: The census work of knowing school-age children's eyesight status was implemented through visual inspection, conventional ophthalmic examination, optometry checks, etc. The results were compared with other domestic epidemiological data. RESULTS: Altogether 536 people with low vision were identified through survey and the rate was 21.12%. Among those people, the number of myopia patients accounted for 80.59% and the prevalence rate was 17.02%. Besides, the prevalence rate of presbyopia was 2.05%, amblyopia 2.76%, strabismus 1.02%, ocular trauma 0.95%, and congenital eye disease 0.71%. CONCLUSION: The prevalence rate of low vision was related with several factors such as gender and nationality. The rate increases with age and the myopia is the primary element that causes low vision.

  1. Blunt abdominal trauma and hollow viscus injury in children: The diagnostic value of plain radiography

    International Nuclear Information System (INIS)

    Although blunt abdominal trauma is common in children, the G-I tract is involved only rarely. However, this paper deals with a series of 24 cases in whom a hollow viscus was injured. We present the radiological and operative findings as well as the results of subsequent radiological workup in patients who had no surgery. Contrary to the recent trend which stresses early abdominal CT as critically important for guiding treatment we have retained a more conservative attitude. Our present protocol includes plain radiography frequently combined with sonographic screening of the abdomen. In patients with stable vital signs and when necessary, we follow up with scintigraphy. CT is reserved for complicated cases with obscure clinical manifestations which do not fit the plain radiological findings and also cases running an unexpected course. (orig.)

Amebic liver abscess (ALA) is the most common extraintestinal form of invasive amebiasis and is a serious life-threatening disease in children. Recent experience indicates the prognosis of ALA in childhood to be improved with early identification of abscesses and prompt institution of treatment. The authors incorporate experience with a case of ALA in infancy with a review of current literature (1974-1983) to delineate clinical and radiologic features of ALA in childhood and further define the role of hepatic imaging in the diagnosis and treatment.

    Full Text Available Structural equation modeling (SEM is an important statistical tool for evaluating complex relations in several research areas. In epidemiology, the use and discussion of SEM have been limited thus far. This article presents basic principles and concepts in SEM, including an application using epidemiological data analysis from a study on the determinants of cognitive development in young children, considering constructs related to organization of the child's home environment, parenting style, and the child's health status. The relations between the constructs and cognitive development were measured. The results showed a positive association between psychosocial stimulus at home and cognitive development in young children. The article presents the contributions by SEM to epidemiology, highlighting the need for an a priori theoretical model for improving the study of epidemiological questions from a new perspective.

    Full Text Available INTRODUCTION: Worldwide, a minority of disordered children/adolescents receives mental health assistance. In order to improve service access, it is important to investigate factors that influence the process leading to receiving care. Data on frequency and barriers for mental health service use (MHSU among Brazilian children/adolescents are extremely scarce and are needed to guide public policy. OBJECTIVES: To establish the frequency of MHSU among 6-to-16-year-old with psychiatric disorders from four Brazilian regions; and to identify structural/psychosocial/demographic barriers associated with child/adolescent MHSU. METHODS: Multicenter cross-sectional-study involving four towns from four out of five Brazilian regions. In each town, a representative sample of elementary public school students was randomly selected (sample: 1,721. Child/adolescent MHSU was defined as being seen by a psychologist/psychiatrist/neurologist in the previous 12 months. Standardized instruments measured: (1 children/adolescent characteristics [(1.1 Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS-PL-psychiatric disorders; (1.2 Ten Questions Screen-neurodevelopment problems; (1.3 two subtests of WISC-III-estimated IQ; (1.4 Academic Performance Test-school performance], (2 factors related to mothers/main caregivers (Self-Reporting Questionnaire-anxiety/depression, (3 family (Brazilian Research-Companies-Association's Questionnaire-SES. RESULTS: Only 19.8% of children/adolescents with psychiatric disorder have used mental health services in the previous 12 months. Multiple logistic regression modeling identified five factors associated with lower rates of MHSU (female gender, adequate school performance, mother/main caregiver living with a partner, lower SES, residing in deprived Brazilian regions regardless of the presence of any psychiatric disorders/neurodevelopmental problems.

    Introduction: The most common clinical sign in pediatric cardiology is a heart murmur (organic and inorganic). Organic are sign of heart disease, while inorganic (basically divided into accidental and functional) murmurs occur on anatomically healthy heart. Aim: To determine the justification of the application of the methods of cardiac treatment. Patients and methods: Study included 116 children aged from 1 to 15 years, who were referred due to cardiac treatment to Pediatric Clinic, of Sarajevo University Clinical Center. Results: The first group consisted of children with innocent heart murmur, 97 (53 males). The second group consisted of patients with organic murmur, 19 (13 males). The average age of the first group was 7.69 (1.01–15.01) years old, and of the second group 3.15 (1.01- 8.06) years old, and there is a significant difference between these two groups (p <0.001). Medical history questions about potentially harmful habits of mother in pregnancy, found significant differences in the frequency of the existence of habits between the first and second groups of subjects (14.44% vs. 85.1%, p = 0.013). The values of the pulse of patients showed statistically significant difference (p = 0.012). The most common place of the murmurs’ appearance is the second left intercostal space. In the first group, the most common were vibratory (32.3%) and ejection (31.9%) and in the second the most common were holosystolic (73.7%) murmur. Analyzing the R/S ratio of V1, a significant difference among the two groups was found (mean 0.78 vs. the values for 1.45, p = 0.003). There is a significance in terms of developed hypertrophy of the heart cavities (BVH) between the two groups. The most common accidental murmur was classic vibratory Still’s murmurs (55.43%) and the most common congenital heart defects was ASD (36.8%). Conclusions: A heart murmur itself, should not be the purpose of auscultation. One of the tasks of pediatricians, pediatric cardiologists in particular

    Although the true incidence of urinary tract infections (UTIs) in children is difficult to estimate, they are one of the most common bacterial infections seen by clinicians who care for young children. Except for the first 8 to 12 weeks of life, when infection of the urinary tact may be secondary to a haematogenous source, UTI is believed to arise by the ascending route after entry of bacteria via the urethra. Enterobacteriaceae are the most common organisms isolated from uncomplicated UTI. Infection with Staphylococcus aureus is rare in children without in-dwelling catheters or other sources of infection, and coagulase-negative staphylococci and Candida spp. are associated with infections after instrumentation of the urinary tract. The diagnosis of UTI in young children is important as it is a marker for urinary tract abnormalities and, in the newborn, may be associated with bacteraemia. Early diagnosis is critical to preserve renal function of the growing kidney. A urine specimen for culture is necessary to document a UTI in a young child. Prior to culture, urinalysis may be useful to detect findings supporting a presumptive diagnosis of UTI. The goals of the management of UTI in a young child are: (i) prompt diagnosis of concomitant bacteraemia or meningitis, particularly in the infant; (ii) prevention of progressive renal disease by prompt eradication of the bacterial pathogen, identification of abnormalities of the urinary tract and prevention of recurrent infections; and (iii) resolution of the acute symptoms of the infection. Delay in initiation of the antibacterial therapy is associated with an increased risk of renal scarring. The initial choice of antibacterial therapy is based on the knowledge of the predominant pathogens in the patient's age group, antibacterial sensitivity patterns in the practice area, the clinical status of the patient and the opportunity for close follow-up. Imaging studies to detect congenital or acquired abnormalities are

    Full Text Available This study was aimed to describe the endoscopic picture and laboratory findings in children with chronic abdominal pain and to determine the utility of nodular gastritis in diagnosing HPI in these patients. This prospective study was done between November, 2004 and May, 2007. A total of 70 patients (36 male and 34 female aged 3-14 years, underwent upper endoscopy. H-pylori infection was diagnosed when both urease test and histology were positive for the infection. Seventy percent (n = 49 of them were diagnosed to have endoscopic nodular gastritis. HPI was confirmed in 33 (47.1% of 70 patients. The endoscopic antral nodularity had a sensitivity of 100%, specificity of 56.8%, positive predictive value of 67.3%, negative predictive value of 100% and a positive LR of 2.32 for diagnosis of HPI. It may be recommended that if nodular gastritis observed in a pediatric patient with chronic abdominal pain he/she should be investigated to exclude HPI otherwise no further work up is necessary to confirm HPI.

  16. Diagnostic evaluation of chronic inflammatory intestinal diseases in children and adolescents: MRI with true-FISP as new gold standard?

    International Nuclear Information System (INIS)

    Purpose: to evaluate the impact of magnetic resonance imaging (MRI) with use of True-FISP sequences in the evaluation of inflammatory bowel-wall changes in children and adolescents with Crohn's disease. Furthermore, the diagnostic procedure in children and adolescents with chronic inflammatory bowel disease (IBD) will be discussed in light of the relevant literature. Material and methods: twenty-four children and adolescents aged between 7 and 21 years with suspected or known IBD underwent MRI on a 1.5T-scanner (Philips ACS-NT, Best, Netherlands). One hour after 11 of a 2.5% mannitol solution was given orally, MR imaging was performed using coronal HASTE-M2D, coronal fat-suppressed T2-TSE, axial dynamic T1-weighted GE-sequences before and after i.v.-contrast material injection (0.1 mmol/kg Gd-DTPA) and using a 2D-balanced-FFE-sequence (True-FISP) before and after i.v.-contrast material injection in coronal and axial planes. The MR-images were correlated with endoscopy and the clinical findings. In 14 patients, a recently performed conventional radiographic enteroclysis was available. Each performed MRI sequence was evaluated by three experienced radiologists regarding the sensitivity and specificity of each sequence in the detection of inflammatory bowel wall changes. In addition, the image quality was assessed regarding the different tissue contrasts and the susceptibility to artifacts. The distension of the bowel wall and the patients' acceptance of the MRI examination were recorded. Results: with a sensitivity in detecting inflammatory small bowel changes of 93.3% (axial pre-contrast, coronal post-contrast) and 100% (axial post-contrast, coronal pre-contrast), the True-FISP outnumbers the other performed sequences (T1 = 80%, HASTE = 13.3% and T2-TSE = 53.3%). The difference between True-FISP and contrast-enhanced T1 was not statistically significant, whereas the difference between True-FISP and HASTE and T2-TSE, respectively. (orig.)

    chain RNA molecule. It is characterised by a high degree of genomic heterogeneity, whose evolutionary consequence in the long term is the appearance of genetically different viral groups, genotypes and quasispecies. There are different diagnostic techniques for detecting hepatitis C virus infection. Serological assays: the detection of specific IgG against HCV by means of enzyme immunoassays is the most practical method for diagnosing infection by this virus. Supplementary immunblot tests are employed to confirm the specificity of the results of the EIA test. Molecular assays: qualitative and quantitative techniques have been developed for detecting RNA-HCV, based on the direct detection of the virions. The pathogeny of hepatitis C is not well understood. Its world prevalence is estimated at some 3%, which is why routine screening for its detection is not recommended. HCV transmission basically occurs through percutaneous exposure to infected blood, with higher rates observed in imprisoned persons, vagabonds, intravenous drug addicts, haemophiliacs and patients on haemodialysis. Although it can be transmitted sexually, it seems that this path is not very efficient, with a greater prevalence observed in persons with multiple sexual partners. Vertical transmission is estimated at some 2%, reaching 20% in cases of maternal coinfection with HIV.

    The worldwide incidence of malignant melanoma is increasing. The number of pigmented naevi and amount of solar exposure are important risk factors. The aim of this study was to characterize a paediatric population (from Lleida, Catalonia, Spain) in terms of phenotype, sun behaviour and naevi prevalence. Data on the numbers and distributions of acquired naevi in 369 children, aged 4, 8 and 14 years, were collected and correlated with age, sex, skin phototype and environmental factors (annual/lifetime intermittent and chronic sun exposure, sunburns and sunscreen use). The density of naevi increased with age. Boys had more naevi on the trunk and girls had more naevi on the legs. Children with light skin phototype had more naevi. A higher level of accumulated sun exposure correlated with a higher number of naevi in children with non-adequate sunscreen use. In conclusion, several risk factors associated with naevi density and distribution were found, as previously reported by others. Multivariate analysis confirmed a protective role of sunscreen in the development of acquired melanocytic naevi. PMID:26551264

    Objective. The aim of this work was to define the prevalence of back pain in children and youth aged 10–19 from the southeast of Poland. Material and Methods. The cross-sectional study included 1089 students (547 girls and 542 boys) aged 10–19. The prevalence of back pain, its intensity, location, and situations in which it occurred were assessed with a questionnaire. Results. Among 1089 respondents, 830 (76.2%) admitted that they had experienced back pain at various frequencies within the year preceding the study. Back pain was located mainly in the lumbar segment (74.8%). Mild pains were dominant, which was declared by 44.7% of the respondents. Girls experienced back pain significantly more frequently than boys (52.2% versus 47.8%, P < 0.05). Conclusions. The research revealed that back pain is a common phenomenon. The prevalence of back pain in children and youth living in southeast Poland is similar to the frequency of occurrence of such complaints occurring in peers in other countries. It seems significant to monitor the remaining regions of Poland in order to define the scale of the problem and to look for the risk factors of back pain in children and youth to undertake efficient prophylactic actions.

    Children involved with child protection services (CPS) are diagnosed and treated for attention-deficit hyperactivity disorder (ADHD) at higher rates than the general population. Children with maltreatment histories are much more likely to have other factors contributing to behavioural and attentional regulation difficulties that may overlap with or mimic ADHD-like symptoms, including language and learning problems, post-traumatic stress disorder, attachment difficulties, mood disorders and anxiety disorders. A higher number of children in the child welfare system are diagnosed with ADHD and provided with psychotropic medications under a group care setting compared with family-based, foster care and kinship care settings. However, children's behavioural trajectories change over time while in care. A reassessment in the approach to ADHD-like symptoms in children exposed to confirmed (or suspected) maltreatment (e.g. neglect, abuse) is required. Diagnosis should be conducted within a multidisciplinary team and practice guidelines regarding ADHD diagnostic and management practices for children in CPS care are warranted both in the USA and in Canada. Increased education for caregivers, teachers and child welfare staff on the effects of maltreatment and often perplexing relationship with ADHD-like symptoms and co-morbid disorders is also necessary. Increased partnerships are needed to ensure the mental well-being of children with child protection involvement. PMID:24942100

    This study reports the results of a systematic screening for respiratory viruses in pediatric outpatients from an emergency department (ED) in southern Brazil during two consecutive influenza seasons. Children eligible for enrollment in this study were aged 24-59 months and presented with acute respiratory symptoms and fever. Naso- and oropharyngeal swabs were collected and multiplex reverse transcription PCR (RT-PCR) was performed to identify the respiratory viruses involved. In total, 492 children were included in this study: 248 in 2010 and 244 in 2011. In 2010, 136 samples (55%) were found to be positive for at least one virus and the most frequently detected viruses were human rhinovirus (HRV) (18%), adenovirus (AdV) (13%), and human coronavirus (CoV) (5%). In 2011, 158 samples (65%) were found to be positive for at least one virus, and the most frequently detected were HRV (29%), AdV (12%), and enterovirus (9%). Further, the presence of asthma (OR, 3.17; 95% CI, 1.86-5.46) was independently associated with HRV infection, whereas fever was associated with AdV (OR, 3.86; 95% CI, 1.31-16.52) and influenza infections (OR, 3.74; 95% CI, 1.26-16.06). Ten patients (2%) were diagnosed with pneumonia, and six of these tested positive for viral infection (4 HRV, 1 RSV, and 1 AdV). Thus, this study identified the most common respiratory viruses found in preschool children in the study region and demonstrated their high frequency, highlighting the need for improved data collection, and case management in order to stimulate preventive measures against these infections.

    This volume is a compendium of peer-reviewed papers presented at the Symposium on Exposure Measurement and Evaluation Methods for Epidemiology, cosponsored in 1985 by the Health Effects Research Laboratory, USEPA, and the Division of Environmental Chemistry of the American Chemical Society. The book is divided into four sections: Use of Biological Monitoring to Assess Exposure, Epidemiologic Considerations for Assessing Exposure, Health and Exposure Data Bases, and Assessment of Exposure to Environmental Contaminants for Epidemiologic Studies. Both background papers and detailed reports of human studies are presented. The Biological Monitoring section contains reports of efforts to quantify adducts in blood and urine samples. In the section on Epidemiologic Considerations the feasibility of conducting epidemiologic studies of persons residing near hazardous waste sites and those exposed to arsenic in drinking water is described. The review of Data Bases includes government and industry water quality monitoring systems, the FDA Market Basket Study, major EPA air monitoring data, the National Database on Body Burden of Toxic chemicals, and the National Human Adipose Tissue Survey. Methods of assessing current exposure and estimating past exposure are detailed in the final section. Exposure to trichloroethylene in shower water, the relationship between water quality and cardiovascular disease, the contribution of environmental lead exposures to pediatric blood lead levels, and data from the TEAM study in which researchers compare indoor, outdoor, and breath analysis of air pollutant exposures are also discussed.

    The incidence of Kawasaki disease in Maghreb countries is apparently low, unlike those living in the province of Quebec, Canada. This retrospective study compared Maghrebi children living in Quebec to the countries of origin, Morocco, Algeria, and Tunisia. The annualized incidence rate in Quebec (18.49/year/100 000 children under 5 years of age) was 4 to 12 times higher than in Tunisia, Morocco, and Algeria (0.95, 4.52, and 3.15, respectively). The prevalence of incomplete diagnostic criteria was higher in Quebec at 39%, Morocco 43%, and Tunisia 39% compared to Algeria at 8%, with minimal delayed diagnosis (7%) only in Quebec compared to 30%, 35%, and 62%, respectively (P aneurysms was comparable however (11% in Quebec vs 4%, 10%, and 25%, in Tunisia, Morocco, and Algeria, respectively; P = .31). The higher incidence of Kawasaki disease in the Maghreb community in Quebec versus the countries of origin seems due to underdiagnosis, which represents a public health concern in those countries.

    Full Text Available Abstract Background As the various systems in the body are inter-connected to form a single structural unit, a pathological condition in one area can also affect other areas. There are many known correlations between the visual and motor system. The importance of visual function, particularly the paracentral peripheral field of view, in motor coordination, ambulation and the maintenance of balance has been amply demonstrated. In line with current medical principles, which are moving towards a more holistic view of the human body, this study aims to investigate, in an interdisciplinary manner, the incidence of dental malocclusions together with posture and eye convergence disorders. Methods Six hundred and five children attending at the 3rd, 4th and 5th years of seven Genoa primary schools were examined. Each child underwent the following examinations: (i dental/occlusal; (ii orthoptic; and (iii postural. Occlusal data concerned the presence of cross-bite, midline deviation with a mandibular shift, bad habits and deep or open bite. Postural assessment involved frontal and lateral inspection, investigation during trunk flexion and ambulation, and note of any asymmetry in the lower limbs. The recorded orthoptic data included those pertaining to ocular dominance, a cover test, convergence and the Brock string test. Results A prevalence of cases with an unphysiological gait was found in patients with overjet (14.70% or overbite (14.87%, while the percentage of patients with normal occlusion that showed an unphysiological gait was 13.08%. Also, about 93.8%–94.2% of children showed normal legs without dysmetry, with no difference in respect to the type of occlusion. Subjects with an open bite or deep bite showed a slightly different distribution of right or left dominant eyes. Conclusion About 13% of children showed a pathological gait and, among them, vertical anomalies of occlusion (deep bite or open bite were prevalent with respect to the other

    To evaluate the predominant human adenovirus (HAdV) species and types associated with pediatric respiratory infections, nasopharyngeal swabs were collected from otherwise healthy children attending an emergency room in Milan, Italy, due to a respiratory tract infection from January 1 to February 28 of two subsequent years, 2013 and 2014. The HAdVs were detected using a respiratory virus panel fast assay (xTAG RVP FAST v2) and with a HAdV-specific real-time polymerase chain reaction; their nucleotides were sequenced, and they were tested for positive selection. Among 307 nasopharyngeal samples, 61 (19.9%) tested positive for HAdV. HAdV was the only virus detected in 31/61 (50.8%) cases, whereas it was found in association with one other virus in 25 (41.0%) cases and with two or more viruses in 5 (8.2%) cases. Human Enterovirus/human rhinovirus and respiratory syncytial virus were the most common co-infecting viral agents and were found in 12 (19.7%) and 7 (11.5%) samples, respectively. Overall, the HAdV strain sequences analyzed were highly conserved. In comparison to HAdV-negative children, those infected with HAdV had a reduced frequency of lower respiratory tract involvement (36.1% vs 55.2%; p = 0.007), wheezing (0.0% vs 12.5%; p = 0.004), and hospitalization (27.9% vs 56.1%; p<0.001). Antibiotic therapy and white blood cell counts were more frequently prescribed (91.9% vs 57.1%; p = 0.04) and higher (17,244 ± 7,737 vs 9,565 ± 3,211 cells/μL; p = 0.04), respectively, in children infected by HAdV-C than among those infected by HAdV-B. On the contrary, those infected by HAdV-B had more frequently lower respiratory tract involvement (57.1% vs 29.7%) but difference did not reach statistical significant (p = 0.21). Children with high viral load were absent from child care attendance for a longer period of time (14.5 ± 7.5 vs 5.5 ± 3.2 days; p = 0.002) and had higher C reactive protein levels (41.3 ± 78.5 vs 5.4 ± 9.6 μg/dL; p = 0.03).

    Full Text Available Abstract Background To determine the prevalence of asthma symptoms in a sample of Greek children aged 10–12 years, and to evaluate these rates in relation to anthropometric, lifestyle characteristics and dietary habits. Methods During 2006, 700 schoolchildren (323 male and 377 female, aged 10–12 years (4th to 6th school grade, were selected from 18 schools located in the greater Athens area. The schools were randomly selected from a list provided by the regional educational offices. To achieve a representative sample the schools enrolled were selected from various region of the Athens area. For each child a questionnaire was completed that was developed for the purposes of the study to retrieve information on: age, sex, school class, other socio-demographic characteristics, anthropometric measurements, dietary habits (through a semi-quantitative Food Frequency Questionnaire and physical activity status; the presence of asthma and allergies was assessed by the standard ISAAC questionnaire. Results The prevalence of wheezing in the past was 25% in boys and 19% in girls, while the prevalence of current wheezing was 9.0% in boys and 5.8% in girls. The prevalence of any asthma symptoms was 27.6% in boys and 20.4% in girls. Multiple logistic regression analysis revealed that increased body weight and sedentary lifestyle is associated with asthma symptoms only in boys. Conclusion The present cross-sectional study cannot establish causal relationships between asthma and increased body weight of schoolchildren; however, our findings underline the associations between asthma, increased body weight, and physical activity at population level, and urge for actions that should be taken by public health policy makers in order to prevent these conditions among children.

    Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders in children. Although the mechanisms that lead to the development of ADHD remain unclear, genetic and environmental factors have been implicated. These include heavy metals and chemical exposures, nutritional and lifestyle/psychosocial factors. The aim of this review was to investigate the association between ADHD or ADHD-related symptoms and widespread environmental factors such as phthalates, bisphenol A (BPA), tobacco smoke, polycyclic aromatic hydrocarbons (PAHs), polyfluoroalkyl chemicals (PFCs) and alcohol. Medline, PubMed and Ebsco search was performed to identify the studies which analyze the association of prenatal and postnatal child exposure to environmental toxicants and lifestyle factors and ADHD or ADHD-related symptoms. The review is restricted to human studies published since 2000 in English in peer reviewed journals. Despite much research has been done on the association between environmental risk factors and ADHD or ADHD symptoms, results are not consistent. Most studies in this field, focused on exposure to tobacco smoke, found an association between that exposure and ADHD and ADHD symptoms. On the other hand, the impact of phthalates, BPA, PFCs, PAHs and alcohol is less frequently investigated and does not allow a firm conclusion regarding the association with the outcomes of interest.

    AbstractBackgroundAttention Deficit Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder characterised by the symptoms of inattention, impulsivity and hyperactivity. ADHD was once perceived as a condition of childhood only; however increasing evidence has highlighted the existence of ADHD in older adolescents and adults. Estimates for the prevalence of ADHD in adults range from 2.5–4%. Few data exist on the prescribing trends of the stimulants methylphenidate and dexamfetamine, and the non-stimulant atomoxetine in the UK. The aim of this study was to investigate the annual prevalence and incidence of pharmacologically treated ADHD in children, adolescents and adults in UK primary care.MethodsThe Health Improvement Network (THIN) database was used to identify all patients aged over 6 years with a diagnosis of ADHD\\/hyperkinetic disorder and a prescription for methylphenidate, dexamfetamine or atomoxetine from 2003–2008. Annual prevalence and incidence of pharmacologically treated ADHD were calculated by age category and sex.ResultsThe source population comprised 3,529,615 patients (48.9% male). A total of 118,929 prescriptions were recorded for the 4,530 patients in the pharmacologically treated ADHD cohort during the 6-year study. Prevalence (per 1000 persons in the mid-year THIN population) increased within each age category from 2003 to 2008 [6–12 years: from 4.8 (95% CI: 4.5–5.1) to 9.2 (95% CI: 8.8–9.6); 13–17 years: from 3.6 (95% CI: 3.3–3.9) to 7.4 (95% CI: 7.0–7.8); 18–24 years: from 0.3 (95% CI: 0.2–0.3) to 1.1 (95% CI: 1.0–1.3); 25–45 years: from 0.02 (95% CI: 0.01–0.03) to 0.08 (95% CI: 0.06–0.10); >45 years: from 0.01 (95% CI: 0.00–0.01) to 0.02 (95% CI: 0.01–0.03).

    The aim of the present study was to determine the diagnostic value of soluble urokinase plasminogen activator receptor (suPAR) in pediatric patients with febrile neutropenia. A prospective case-control study was performed. Patients included 29 children with febrile neutropenia (FN) and 27 control subjects without any infection or immunosuppressive condition. Blood samples were obtained on the day of admission and on the 4th to 7th days of the hospital stay. The median (minimum-maximum) serum levels of suPAR obtained on the first day of the admission were 2.08 (0.93-9.42) and 2.22 (1.08-5.13) ng/mL for the FN group and the control group, respectively. The median serum levels of suPAR in the FN and control groups were not significantly different (P = .053). The mean serum suPAR level was significantly higher in nonsurvivors than in survivors in the FN group (P < .05). In the FN group, the area under the receiver operating characteristics curve (AUCROC) for suPAR was 0.546, but no optimum cutoff value, sensitivity, specificity, negative predictive value (NPV), or positive predictive value (PPV) was obtained. We conclude that suPAR is not useful as a diagnostic biomarker in children with febrile neutropenia; however, persistent high serum suPAR level may predict mortality in FN in children. PMID:27057782

    The main objective of this study was to investigate the epidemiology, drug resistance and β-lactamase genotype distribution of enteropathogenic Escherichia coli (EPEC) isolated from pediatric patients with diarrhea in southern China. The prevalence of EPEC in children with diarrhea was 3.53%. The commonest serotypes were O55:K59 and O126:K71, and the typical EPEC were more prevalent than atypical EPEC (51 vs 7). Isolates from this region were most commonly found to be resistant to ampicillin and cotrimoxazole, followed by chloramphenicol, ceftriaxone, and ceftazidime. More than 96% of the strains were susceptible to cefoperazone/sulbactam and imipenem. The most common β-lactamase genotypes identified in 58 strains were blaCTX-M-1 (60.3%), blaTEM (56.9%), blaCTX-M-9 (27.6%), and blaSHV (15.5%). Among 58 isolates, 22 strains were found to harbor one β-lactamase gene, and the proportions of resistance to ampicillin, cotrimoxazole, chloramphenicol, ceftriaxone, and ceftazidime, were 81.8%, 63.6%, 40.9%, 18.2%, and 9.1%, respectively. A further 30 strains carrying multiple β-lactamase genes had increased resistance to the above antimicrobial agents (100%, 83.3%, 70.0%, 60.0%, and 30.0%, respectively). In contrast, antibiotic resistance in the last 6 strains without a detectable β-lactamase gene was substantially reduced. Drug resistance may be associated with the β-lactamase gene number, with a greater the number of β-lactamase genes resulting in higher antibiotic resistance. PMID:25672408

    Full Text Available Hepatocellular Carcinoma (HCC is among the most common of solid human malignancies, with an annual incidence of 100.000 new cases. The worldwide distribution of HCC is not uniform, the highest rates are found in Southeast Asia and Sub-Saharian Africa. The HCC imcidence in Romania varies between 4-10 cases to 100.000 inhabitants per year. HCC is more likely to develop in men than in women, the sex ratio being approximately 8:1 in high-incidence areas. Chronic hepatitis B virus and C virus have been implicated as important etiologic factors in the development of HCC, being responsable for 80% of the cases. The most of the carcinomas are developped on the cirrhotic liver. A number of other risk factors also are involved in HCC: diabetes mellitus, obesity, chronic ethilism, oral contraceptives, smoking and dietary intake of aphlatoxines. HCC is usually diagnosed at a late stage. The clinical presentation are not typical, suggesting only the basic liver pathology. Ultrasounds, CT- scan and MRI confirm the presence of a mass in the liver. Alfa-fetoprotein (AFP, alfa-fetoprotein L3 fraction and des-gammacarboxiprotrombina (also known as PIVKA II test are considered as serological markers for HCC. The indication of screening is for the patients with liver cirrhosis or chronic hepatitis B and/ or C virus. The level of AFP and liver ultrasounds are mandatory to be done as screening tests to every 6 months to the risk patients.

    Full Text Available Background: Childhood masturbation (CM is considered a variant of normal sexual behavior; however, it is commonly misdiagnosed as epilepsy and movement disorders. As the first study from Iran, we analyzed a large population of infants and children with CM in a case-control study and evaluated the value of mucus in urine analysis as an alternative diagnostic tool for CM. Methods: A total of 623 children referred to the Pediatric Neurology Clinic of Imam Khomeini Hospital for an evaluation of seizure or movement disorders were studied between 2008 and 2011. Totally, 359 children were found to have masturbatory behaviors (Group A and the rest (264 were assigned to Group B. CM was diagnosed by direct observation. Collected data comprised demographic characteristics, clinical and neurodevelopmental examinations, laboratory findings (particularly urine analysis, and electrocardiography. Results: The age of the children with CM was below 12 years old, and the girl-to-boy ratio was 7:1. Mucus in urine was positive in 357 (99.44% children in Group A and 22 (8.3% in Group B (P<0.001. A significant correlation was found between the presence of mucus in urine and masturbatory behaviors (P<0.001. Conclusion: Our findings suggest that the presence of mucus in urine can be used as an alternative laboratory test in children with CM below 12 years old and even in infants (≤24 months old. Further studies are needed to confirm the results.

    The global statistics of diabetes mellitus in year 2013 indicated, about 382 million people had this disease worldwide, with type 2 diabetes making up about 90 % of the cases. This is equal to 8.3 % of the adult population with equal rates in both women and men. In year 2012 and 2013 diabetes resulted in mortality of 1.5-5.1 million people per year, making it the 8th leading cause of death in the world. It is predicted that by year 2035 about 592 million people will die of diabetes. The economic cost of diabetes seems to have increased worldwide. An average age of onset of diabetes is 42.5 years and could be due to consumption of high sugar and high-calorie diet, low physical activity, genetic susceptibility, and lifestyle. Approximately 8 % children and about 26 % young adults have diabetes mellitus in the world. The results of epidemiological study of type 1 diabetes mellitus (T1D) are presented by demographic, geographic, biologic, cultural, and other factors in human populations. The prevalence of T1D has been increased by 2-5 % worldwide and its prevalence is approximately one in 300 in US by 18 years of age. The epidemiological studies are important to study the role, causes, clinical care, prevention, and treatment of type1 diabetes in pregnant women and their children before and after birth. In this article, causes, diagnosis, symptoms, treatment and medications, and epidemiology of diabetes will be described. PMID:25711186

    Wound sepsis is one of the main causes of death in patients with severe burn and trauma. The high incidence of burn wound sepsis in children is attributed to their imperfect immune system function, poor resistance against infection, and the weakened skin barrier function after burn. The key to reduce the mortality of pediatric patients with burn wound sepsis is to enhance the understanding of its etiology, epidemiology, pathogenesis, and diagnostic criteria, in order to improve its early diagnosis and treatment.

    2008-02-01

    Full Text Available Abstract Background Levels of pesticides and other compounds in carpet dust can be useful indicators of exposure in epidemiologic studies, particularly for young children who are in frequent contact with carpets. The high-volume surface sampler (HVS3 is often used to collect dust samples in the room in which the child had spent the most time. This method can be expensive and cumbersome, and it has been suggested that an easier method would be to remove dust that had already been collected with the household vacuum cleaner. However, the household vacuum integrates exposures over multiple rooms, some of which are not relevant to the child's exposure, and differences in vacuuming equipment and practices could affect the chemical concentration data. Here, we compare levels of pesticides and other compounds in dust from household vacuums to that collected using the HVS3. Methods Both methods were used in 45 homes in California. HVS3 samples were collected in one room, while the household vacuum had typically been used throughout the home. The samples were analyzed for 64 organic compounds, including pesticides, polycyclic aromatic hydrocarbons, and polychlorinated biphenyls (PCBs, using GC/MS in multiple ion monitoring mode; and for nine metals using conventional microwave-assisted acid digestion combined with ICP/MS. Results The methods agreed in detecting the presence of the compounds 77% to 100% of the time (median 95%. For compounds with less than 100% agreement, neither method was consistently more sensitive than the other. Median concentrations were similar for most analytes, and Spearman correlation coefficients were 0.60 or higher except for allethrin (0.15 and malathion (0.24, which were detected infrequently, and benzo(kfluoranthene (0.55, benzo(apyrene (0.55, PCB 105 (0.54, PCB 118 (0.54, and PCB 138 (0.58. Assuming that the HVS3 method is the "gold standard," the extent to which the household vacuum cleaner method yields relative risk

    Objective To explore and evaluate the diagnostic procedure for chronic cough in children.Methods One hundred and eleven patients from the First Affiliated Hospital of Guangxi Medical University with chronic cough between December 2008 and January 2010 were included in the study. Etiologic diagnostic procedure suggested for children by Pediatric Branch of Chinese Medical Association was implemented to manage the patients,and the etiological data were analyzed. Results The causes of chronic cough were identified in 109 cases (98% of the total cases). A single cause of cough was diagnosed in 60 patients (54%), multiple potential causes of cough were recognized in 49 patients (44%), including two coexisting causes in 47 patients (42%) and three in 2 patients (2%).The causes of chronic cough in children were: 45 (40%) with cough variant asthma, 34 (30%) with upper airway cough syndrome, 19 (17%) with postinfection cough, 5 (5%) with allergic cough, 4 (4%) with Tourette's syndrome, 1 (1%) with psychogenic cough and others 3 (3%). Conclusions Etiologic diagnosis of chronic cough in children could be made by integrating the current diagnostic procedures with individual and dynamic evaluation and individual treatment. Improvement of clinical symptom was a main observation point; diagnosis should be revised timely if new diagnostic clues appear. It is important to pay attention to the possibility of coexistence of multiple causes.

    Objective. To study the value of serum insulin-like growth factor binding protein-3 (IGFBP-3) levels in differential diagnosis of growth hormone deficiency (GHD). Methods. To measure serum IGFBP-3 levels by RIA in normal children and adolescents, GHD children and short-stature children without GHD. Results. Serum level of IGFBP-3 in 129 children with untreated GHD and with no pubertal development was 1.6± 0.9 mg/L, which was less than that in normal group of the same age, but overlapped with the normal children in Tanner stage I. After six -month treatment with recombinant human growth hormone (rhGH), serum level of IGFBP-3 in 59 GHD significantly increased from 1.3± 0.7 mg/L to 2.7± 0.9 mg/L, accompanied by an increase of body heights, growth velocities and serum level of IGF-1. Serum level of IGFBP-3 in 55 short-stature children without GHD was 3.3± 2.2 mg/L, which was not significantly different from that in normal group. Conclusion. Serum IGFBP-3 level can reflect the status of GH secretion in children with GHD and is a useful marker for differential diagnosis of GHD.

    Ionizing radiation for diagnostic purposes are an indispensable tool in modern medicine. The increasing use of computed tomography (CT) in children and adolescents is of concern both from the point of view of radio-protection and public health. children are more sensitive to the carcinogenic effects of ionizing radiation than adults. Children also have a higher life expectancy to show any detrimental effect. Furthermore, because of their smaller mass, CT scans in children receiving higher doses of radiation in specific organs in adults.

    Full Text Available Stroke is a huge public health problem because of its high morbidity and disability. The epidemiology of stroke is of relevance to construct practical paradigms to tackle this major health issue in the community. Recent data have shown that about 72-86% of strokes are ischemic, 9-18% are due to hemorrhage (intracerebral of subarachnoid and the rest are undefined. The risk factors for stroke are multiple and combined. At present, stroke is no more considered as unavoidable and untreatable. It is an emergency and specialized units and teams improve outcome and lower costs. Death related to stroke is declining in many countries and in both sexes. This decrease in multifactorial. The detection and more effective treatment of hypertension may play an important factor, as well as the improved medical care and improvement in diagnostic procedures. While stroke incidence appears stable and stroke mortality is slowly declining, the absolute magnitude of stroke is likely to grow over the next 30 years. as the population ages, the absolute number of stroke victims and demands on healthcare and other support systems is likely to increase substantially in the future. Keeping this in perspective, this chapter shall focus on the epidemiology of stroke in the world and in Indian, in particular.

    International Nuclear Information System (INIS)

    CT examinations were carried out in 75 high-risk and premature children: 40% of these were re-examined at a later stage in infancy. All children were also examined under the aspect of developmental neurology. The small number of cases made it impossible to make a reliable prognosis of the later development of perinatal high-risk patients, especially as the follow-up examinations were discontinued after infancy. Still, the findings have been validated by experience in the meantime. (orig.)

    Full Text Available Abstract Introduction Dehydration and malnutrition commonly occur together among ill children in developing countries. Dehydration (change in total body water is known to alter weight. Although muscle tissue has high water content, it is not known whether mid-upper arm circumference (MUAC may be altered by changes in tissue hydration. We aimed to determine whether rehydration alters MUAC, MUAC Z score (MUACz, weight-for-length Z-score (WFLz and classification of nutritional status among hospitalised Kenyan children admitted with signs of dehydration. Study procedure We enrolled children aged from 3 months to 5 years admitted to a rural Kenyan district hospital with clinical signs compatible with dehydration, and without kwashiorkor. Anthropometric measurements were taken at admission and repeated after 48 hours of treatment, which included rehydration by WHO protocols. Changes in weight observed during this period were considered to be due to changes in hydration status. Results Among 325 children (median age 11 months the median weight gain (rehydration after 48 hours was 0.21 kg, (an increase of 2.9% of admission body weight. Each 1% change in weight was associated with a 0.40 mm (95% CI: 0.30 to 0.44 mm, p Conclusion MUAC is less affected by dehydration than WFLz and is therefore more suitable for nutritional assessment of ill children. However, both WFLz and MUAC misclassify SAM among dehydrated children. Nutritional status should be re-evaluated following rehydration, and management adjusted accordingly.

    Full Text Available Purpose: Genetic factor to bitter taste perception appears to be largely mediated by the TAS2R38 gene. The insensitivity to bitter compounds like 6-n-propylthiouracil (PROP is mediated by this gene. PROP, a pharmacological drug used in treatment of Graves′ disease, proved to be useful tool in determining the genetic sensitivity levels to bitter and sweet taste. The purpose of this study is to show much simpler PROP sensitivity technique for the clinical examiner and its application as a diagnostic aid in Early Childhood Caries (ECC detection among preschool children. Materials and Methods: A total of 119 children belonging to the age group of 36 to 71 months of both sexes, were recruited from A. J. Institute of Dental Sciences, Mangalore (Karnataka. PROP sensitivity test was carried out to determine the inherent genetic ability to taste a bitter or sweet substance. This study used simpler scaling method to find out genetic sensitivity to bitter taste; one who tasted bitter as taster and one who was not able to differentiate/tasted like paper as non-taster. A questionnaire was provided to evaluate their dietary habits and caries experience was recorded. Collected data were tabulated and subjected to statistical analysis. Results: In the total of 119 children the mean dmfs was definitely higher in non-taster children compared to tasters. The tasters had a mean dmfs value of 9.5120 (S.D. 7.0543 and non-tasters had a value of 7.7250 (S.D. 8.33147, which was statistically significant. The results suggested that there was increase in caries experience among the group of non-tasters as compared to tasters. Tasters tended to be sweet dislikers and non-tasters tended to be sweet likers. On the whole, tasters had a bad dentition as compared to non tasters. Conclusion: The PROP sensitivity test (filter paper test proved to be a useful diagnostic tool in determining the genetic sensitivity levels of bitter taste. The knowledge of a child′s taste

It is caused by the soil-dwelling fungi, Coccidioides immitis and C. posadasii, which are present in diverse endemic areas. Climate changes and environmental factors affect the Coccidioides lifecycle and influence infection rates. The incidence of coccidioidomycosis has risen substantially over the past two decades. The vast majority of Coccidioides infections occur in the endemic zones, such as California, Arizona, Mexico, and Central America. Infections occurring outside those zones appear to be increasingly common, and pose unique clinical and public health challenges. It has long been known that elderly persons, pregnant women, and members of certain ethnic groups are at risk for severe or disseminated coccidioidomycosis. In recent years, it has become evident that persons with immunodeficiency diseases, diabetics, transplant recipients, and prisoners are also particularly vulnerable.Keywords: coccidioidomycosis, Coccidioides, epidemiology, incidence, risk factors, geography

    Lysosomal storage disorders (LSDs) are considered to be a rare metabolic disease for the national health forum, clinicians, and scientists. This study aimed to know the prevalence of different LSDs, their geographical variation, and burden on the society. It included 1,110 children from January 2002 to December 2012, having coarse facial features, hepatomegaly or hepatosplenomegaly, skeletal dysplasia, neuroregression, leukodystrophy, developmental delay, cerebral-cerebellar atrophy, and abnormal ophthalmic findings. All subjects were screened for I-cell disease, glycolipid storage disorders (Niemann-Pick disease A/B, Gaucher), and mucopolysaccharide disorders followed by confirmatory lysosomal enzymes study from leucocytes and/or fibroblasts. Niemann-Pick disease-C (NPC) was confirmed by fibroblasts study using filipin stain. Various storage disorders were detected in 387 children (34.8 %) with highest prevalence of glycolipid storage disorders in 48 %, followed by mucopolysaccharide disorders in 22 % and defective sulfatide degradation in 14 % of the children. Less common defects were glycogen degradation defect and protein degradation defect in 5 % each, lysosomal trafficking protein defect in 4 %, and transport defect in 3 % of the patients. This study demonstrates higher incidence of Gaucher disease (16 %) followed by GM2 gangliosidosis that includes Tay-Sachs disease (10 %) and Sandhoff disease (7.8 %) and mucopolysaccharide disorders among all LSDs. Nearly 30 % of the affected children were born to consanguineous parents and this was higher (72 %) in children with Batten disease. Our study also demonstrates two common mutations c.1277_1278insTATC in 14.28 % (4/28) and c.964G>T (p.D322Y) in 10.7 % (3/28) for Tay-Sachs disease in addition to the earlier reported c.1385A>T (p.E462V) mutation in 21.42 % (6/28).

    The assessment of bone healing and loosening of endoprosthesis material was long the primary indication for postoperative projection radiography and CT imaging of the hip joint following trauma and endoprosthesis implantation. With the increasing number of joint-preserving surgery, e. g. of surgical hip luxation and hip arthroscopy for the treatment of femoroacetabular impingement (FAI), high-resolution imaging of intra-articular pathologies before and after surgery has become increasingly important. In this review article, diagnostic imaging of the hip joint is presented following common trauma surgery and orthopedic surgery interventions. The imaging modalities of projection radiography, CT and MRI including direct MR-arthrography are discussed with regard to their diagnostic capability in the postoperative assessment of the hip joint. Among others topics, imaging is discussed following hip arthroplasty, following surgical hip luxation and arthroscopic interventions for the treatment of FAI, as well as following core decompression for avascular necrosis of the femoral head. Moreover, orthopedic interventions of the hip joint in children and adolescents are presented and the dedicated reporting of postoperative imaging is outlined.

To compare the diagnostic performance of CT and MRI for local staging of pediatric renal tumors. The study population was derived from the AREN03B2 study of the Children's Oncology Group. Baseline abdominal imaging performed with both CT and MRI within 30 days of nephrectomy was available for retrospective review in 82 renal tumor cases. Each case was evaluated for capsular penetration, lymph node metastasis, tumor thrombus, preoperative tumor rupture, and synchronous contralateral lesions. The surgical and pathological findings at central review were the reference standard. The sensitivity of CT and MRI for detecting capsular penetration was 68.6% and 62.9%, respectively (P = 0.73), while specificity was 86.5% and 83.8% (P = 1.0). The sensitivity of CT and MRI for detecting lymph node metastasis was 76.5% and 52.9% (P = 0.22), and specificity was 90.4% and 92.3% (P = 1.0). Synchronous contralateral lesions were identified by CT in 4/9 cases and by MRI in 7/9 cases. CT and MRI have similar diagnostic performance for detection of lymph node metastasis and capsular penetration. MR detected more contralateral synchronous lesions; however these were present in a very small number of cases. Either modality can be used for initial loco-regional staging of pediatric renal tumors. (orig.)

  1. Radiation epidemiology: a perspective on Fukushima

    International Nuclear Information System (INIS)

    For nearly 100 years, epidemiologic studies of human populations exposed to ionising radiation have provided quantitative information on health risks. High dose deterministic (tissue reaction) effects result when sufficient numbers of functioning cells are killed, such as in bone marrow depression that can lead to death. Lower dose stochastic effects are probabilistic in nature and include an increased risk of cancer later in life and heritable genetic defects, although genetic conditions in the children of irradiated parents have yet to be convincingly demonstrated. Radiation studies are of diverse populations and include not only the Japanese atomic bomb survivors, but also patients treated with radiation for malignant and non-malignant disease; patients exposed for diagnostic purposes; persons with intakes of radionuclides; workers occupationally exposed; and communities exposed to environmental and accidentally released sources of radiation. Much is known about radiation and its risks. The major unanswered question in radiation epidemiology, however, is not whether radiation causes cancer, but what the level of risk is following low dose (<100 mSv) or low dose rate exposures. Paracelsus is credited with first articulating that the 'poison is in the dose', which for radiation epidemiology translates as 'the lower the dose, the lower the risk' and, an important corollary, the lower the dose, the greater the difficulty in detecting any increase in the number of cancers possibly attributable to radiation. In contrast to the Chernobyl reactor accident, the Fukushima reactor accident has to date resulted in no deterministic effects and no worker deaths. Estimates to date of population doses suggest very low uptakes of radioactive iodine which was a major determinant of the epidemic of thyroid cancer following childhood exposures around Chernobyl. The estimates to date of population doses are also much lower (and the distribution much narrower) than the doses for

    The study comprised 1604 children (49.9% of boys and 50.1% of girls) of age between 6 and 13 years living in the districts of Gdańsk, Elblag, Olsztyn and Toruń. 55.5% of children were from urban area, 44.5% from rural area. This districts have been divided into 3 geographic regions. 1) Olsztyn region: 174 children and the villages near Olsztyn--178 children, 2) Seaside region: Gdańsk and Elblag--358 children and 3 villages situated in the distance less than 60 km from the sea--533 children, 3) Toruń region: Toruń--181 children and villages near Toruń--180 children. A significant relationship between the incidence of goiter and the place of living was found. The presence of goiter was observed in 9.2% of children in Gdańsk and Elblag and in 23% of children in the seaside region (with the peak in Glincz village--35%). In Olsztyn region the incidence was 18.2%, in Toruń region--12.5%. Among 1604 studied subjects in 263 (16.4%) with goiter, the nodular goiter was in 2.3% of cases. The lowest occurrence of goiter was noted in Gdańsk and Elblag. Urinary iodine concentration in children with goiter from Gdańsk and Elblag (123.1 micrograms/l) was higher than in those living in villages in the seaside region (90.8 micrograms/l). The thyroid size as measured by ultrasonography was different in children with and without goiter in each age group. In the age group of 6-8 years it was 4.8 ml in children without goiter and 6.3 ml in children with goiter, in the age group 9-10 years, 5.7 ml and 8.6 ml, in the age group 11-12 years, 6.6 ml and 10.0 ml, in children 13 years old--8.0 ml and 12.1 ml. All the children with goiter have greater body weight and height than those in the same age groups without goiter. 13.2% of studied persons consumed iodized salt. There was no difference in the incidence of goiter in children receiving and not receiving iodized salt (13.4% and 13.1% in all regions). There was also lack of relation between urinary iodine concentration and rate of

  3. Radiation dose to infants, children and adults in X-ray diagnostic radiology-in the case of plain radiography

    International Nuclear Information System (INIS)

    The objective of this study was to evaluate radiation doses to infant, child and adult patients undergoing various types of plain radiography and to compare the doses among them. The doses were measured using newborn, 6-year-child and adult anthropomorphic phantoms, in which photodiode dosimeters were implanted at various tissue and organ positions. Measured doses were used to evaluate organ and effective doses. Organ doses obtained in various types of radiography were lower than 0.7 mGy for adults, 0.3 mGy for children and 0.2 mGy for infants, excepting lens dose of approximately 1 mGy in adult head radiography, where the doses for children and infants lowered to 1/2-1/3 of the doses for adults. Effective doses in various types of head radiography for adults, children and infants were in identical levels in a range of 5-30 μSv. In chest, abdomen and hip-joint radiography, effective doses of 0.02-0.11 mSv for children and 0.02-0.08 mSv for infants were identical to or in a fraction of the doses for adults of 0.06-0.15 mSv. In adult head and spinal radiography, effective doses by International Commission of Radiological Protection (ICRP) Publication 60 lowered respectively to 1/6-1/9 and 1/3-1/9 of the doses listed in United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) 2000.

  5. Diagnostic efficacy and pitfalls of a 64-raw multislice computed tomography scan for mild head injuries in children

    International Nuclear Information System (INIS)

    The aim of this study is to analyze the usefulness of 64-raw multislice computed tomography (CT) scans and bone images of three-dimensional CT (3D-CT) scans for evaluation of mild head injuries in children. Thirteen children (9 boys and 4 girls, less than or equal to 15 years old) with mild head injury were included in the study. Head CT scans obtained within 24 hours after injury. All children had no episodes of loss of consciousness, amnesia, epilepsy, vomiting, and no neurological abnormality on arrival at hospital. We detected 9 positive findings on CT scans, which looked like fracture lines at the frontal bone in 7 cases. The bone images of CT axial views revealed a true fracture in one case in which a skull X-ray could not demonstrate a fracture line, but, other positive findings turned out to be a diploic vein surrounded by a thin bone cortex. All false positive findings were detected in the patients under the age of 6. By the 3D-reconstructive CT scan, it is easier to detect not only the intracranial lesions but also the cranial fracture. But, the diploic vein is apt to be misdiagnosed as the fracture line, especially in patients under the age of 6. (author)

    A child's body size is not accurately reflected by volume CT dose index (CTDI{sub vol}) and dose-length product (DLP). Size-specific dose estimation (SSDE) was introduced recently as a new index of radiation dose. However, it has not yet been established as a diagnostic reference level (DRL). To calculate the SSDE of abdominal/pelvic CT and compare the SSDE with CTDI{sub vol}. To calculate the DRLs of CTDI{sub vol} and SSDE. Our hypotheses are: SSDE values will be greater than CTDI{sub vol}, and our DRL will be smaller than the known DRLs of other countries. The CTDI{sub vol} and DLP of 117 children who underwent abdominal/pelvic CT were collected retrospectively. The SSDE was calculated from the sum of the lateral and anteroposterior diameters. The relationships between body weight and effective diameter and between effective diameter and CTDI{sub vol}/SSDE were compared. Further, the local DRL was compared with the DRLs of other countries. Body weight and effective diameter and effective diameter and SSDE were positively correlated. In children ages 1, 5 and 10 years, the SSDE is closer to the exposure dose of CTDI{sub vol} for the 16-cm phantom, while in children ages 15 years, the SSDE falls between CTDI{sub vol} for the 16-cm phantom and that for the 32-cm phantom. The local DRL was lower than those of other countries. With SSDE, the radiation dose increased with increasing body weight. Since SSDE takes body size into account, it proved to be a useful indicator for estimating the exposure dose. (orig.)

The epidemiology of these serotypes in carriage remains poorly studied because they are rarely detected. We aimed to gain insights into the epidemiology and population structure of serotypes 1, 5 and 7F carried by children in Portugal before PCV10 and PCV13 became widely used. Isolates obtained in cross-sectional studies carried out over a 15-year period (1996-2010 were retrospectively pooled and characterized. Of 5,123 pneumococci obtained, 70 were associated with serotypes 1 (n = 21, 5 (n = 7, and 7F (n = 42. The highest prevalence detected was 3.3% for serotype 1 in 2006, 1% for serotype 5 in 2009, and 3.3% for serotype 7F in 2006; Serotype 1 was associated with PMEN international clones Sweden(1-28(ST306 and Sweden(1-40(ST304; serotype 5 was associated with Colombia(5-19(ST289; and serotype 7F was associated with Netherlands(7F-39(ST191. All these isolates were fully susceptible. Most carriers of serotypes 1 (86%, 5 (86%, and 7F (91% were older than two years but a significant association with older age was only observed for serotype 7F (p = 0.006. Evidence for cross-transmission was obtained. In conclusion, we were able to detect and characterize the rarely carried serotypes 1, 5, and 7F among healthy children in Portugal. These data will constitute an important baseline for upcoming surveillance studies aimed to establish the impact of novel PCVs targeting these serotypes in carriage.

    Allergic respiratory disorders, in particular asthma are increasing in prevalence, which is a global phenomenon. Even though genetic predisposition is one of the factors in children for the increased prevalence - urbanisation, air pollution and environmental tobacco smoke contribute more significantly. Our hospital based study on 20,000 children under the age of 18 years from 1979,1984,1989,1994 and 1999 in the city of Bangalore showed a prevalence of 9%,10.5%,18.5%, 24.5% and 29.5% respectively. The increased prevalence correlated well with demographic changes of the city. Further to the hospital study, a school survey in 12 schools on 6550 children in the age group of 6 to 15 years was undertaken for prevalence of asthma and children were categorized into three groups depending upon the geographical situation of the school in relation to vehicular traffic and the socioeconomic group of children. Group I-Children from schools of heavy traffic area showed prevalence of 19.34%, Group II-Children from heavy traffic region and low socioeconomic population had 31.14% and Group III-Children from low traffic area school had 11.15% respectively. (P: I & II; II & III <0.001). A continuation of study in rural areas showed 5.7% in children of 6-15 years. The persistent asthma also showed an increase from 20% to 27.5% and persistent severe asthma 4% to 6.5% between 1994-99. Various epidemiological spectra of asthma in children are discussed here.

    This study investigated childhood migraine, examining the clinical characteristics of different childhood migraine types, predisposing factors, and possible medical treatments in a sample of children in Serbia. This was the first epidemiological study in Serbia using the operational diagnostic criteria of the International Headache Society. The present study examined 30 636 children between 1988 and 2006, including 15 434 (50.38%) males and 15 202 (49.62%) females, in nine towns in Vojvodina, a northern province in Serbia. Migraine was reported in 2 644 (8.63%) children aged 3 to 7 years, consisting of 1 189 (8.0%) males and 1 455 (9.6%) females. Migraine with aura accounted for 25.55%, migraine without aura for 67.21% and other migraine syndromes for 7.23% of reported migraine sufferers. The mean age of first migraine attack across groups was 5 years and 1.8 months. Migraine with aura was associated with an earlier onset than migraine without aura.Migraine was more frequent among younger groups of children who were breastfed for a shorter period of time. Child healthcare in Vojvodina has a high level of specialization, with more than half of the children reporting migraine diagnosed and treated by neuropediatricians. Socioeconomic status,duration of breastfeeding, birth order, and age of entering full-day nursery care were found to be important factors for childhood migraine. These findings suggest that healthcare providers should educate parents about these predisposing factors, so they can be identified and avoided early.

  13. Optimization of the procedure of cholecystography per os in children as a method of raising its diagnostic informative value

    International Nuclear Information System (INIS)

    Methods of performance of unified cholecystograhy per os were developed on the basis of the results of X-ray and ultrasonic investigations of the gall bladder in 168 children. A method of contrast medium dosage to raise the informative value of cholecystography was proposed. A procedure of taking pictures with a patient lying in a prone position, an X-ray tube being turned in accordance with an angle of gall bladder inclination to the anterior abdominal wall, was worked out, making it possible to detect, with a high degree of reliability, the most common development defects of the gall bladder and to define its true sizes on the basis of X-ray findings

    Full Text Available Childhood psychiatric disorders are estimated to influence about 9 to 21% of relevant age group and interest in this disorders are increasing all over the world. The growing need to child and adolescent mental health leads the task of establishing proposals and policies in this field to become a priority for governments. The first step of such proposals should be determination of prevalence of child and adolescent mental disorders in that country. However, several major methodological problems make it hard to provide accurate prevalence estimates from epidemiological studies. Most common problems are within the fields of sampling, case definition, case ascertainment and data analyses. Such issues increases the costs of studies and hinder to reach large sample sizes. To minimize these problems, investigators have to be careful on choosing the appropriate methodology and diagnostic tools in their studies. Although there are many interviews and questionnaires for screening and diagnosing in child and adolescent psychiatry, only a few of them are suitable for epidemiological research. In parallel with the improvement in all fields of child and adolescent mental health in our country, some of the major screening and diagnosing tools used in prevalence studies in literature have already been translated and validated in Turkish. Most important of this tools for screening purposes are Child Behavior Checklist and Strengths and Difficulties Questionnaire and for diagnosing purposes are Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version and Development and Well-Being Assessment. The aims of this article are to review the methodological problems of epidemiologic studies in child and adolescent psychiatry and to briefly discuss suitable diagnostic tools for extended sampled epidemiologic studies in our country.

    Aiming to describe the place that Chile has in the epidemiological transition, a descriptive study of the changes in demographic and epidemiological profiles of the country during the last 30 years is presented. The important decrease in general and child mortality rates, that has lead to an increase in life expectancy and ageing of the population, is emphasized. A 82% reduction in the proportion of deaths among less than one year old children and a 62% increase in mortality among people 65 years or older is observed. In agreement with these changes, non transmissible chronic diseases appear as the principal cause of mortality (65% of all deaths). However, regarding morbidity, an increase in digestive infectious and sexually transmitted diseases and a decrease in immuno-preventable diseases, excepting measles, is noted. It is concluded that, according to mortality, Chile is in a post transition stage, but there is persistence of some infectious diseases, typical of a pre-transition stage. PMID:8085073

    2000-01-01

    Erosion affects both dentitions but has proved difficult to measure. It has been thought to affect children who are less susceptible to caries but previous studies have been confined to countries where caries prevalence is low. The aims of this study were first, to develop and then investigate the validity of an index to measure erosion in primary teeth. Secondly, to determine the prevalence of erosion in primary incisors amongst kindergarten children in Jeddah and its relat...
